Elacestrant (RAD1901) is a novel, non steroidal oral SERD that has demonstrated single agent activity in heavily pre treated patients with ER+ advanced breast cancer (Bardia et al. J Clin Oncol 35, 2017: suppl; abstr 1014) The primary objective of this study was the visualization and quantification of residual ER binding with FES PET after treatment with elacestrant. Methods: In the RAD1901 106 phase 1 study (NCT02650817) patients with advanced ER+/HER2 breast cancer were treated with elacestrant at two dose levels (200 mg or 400 mg qd orally) for the first 14 days. Tumoral FES uptake was measured at baseline and day 14. After FES PET scan at day 14, all patients received elacestrant 400 mg qd until disease progression or discontinuation due to another cause. Key inclusion criteria included postmenopausal women with advanced ER+/HER2 breast cancer, who have progressed after =6 months of at least 1 line of endocrine treatment in the metastatic setting, with measurable disease according to RECIST criteria v1.1 or clinically evaluable disease. The PET scan was performed 60 min after intravenous injection of 200 MBq FES. Maximum standardized uptake values (SUVmax) were calculated and corrected for background activity. FES positive lesions had a SUVmax >1.5. FES response was defined as a 75% median decrease of SUVmax between the two scans. ESR1 mutation status was determined from circulating tumor DNA collected at multiple time points. Results: Twenty four patients were screened and 16 patients were enrolled (8 at each dose level) Median lines of prior therapy were 3, with 6 (38% patients having previously received fulvestrant and 8 (50% patients harboring at least 1 ESR1 mutation at baseline. Elacestrant demonstrated a median of 88% (range 59 97.1% reduction in tumorFES uptake following 14 days of treatment. Eleven out of 16 patients had >75% reduction in FES uptake at day 14. At the data cutoff date of 2 May 2017, median treatment duration was 8.1 weeks and 8 (50% patients remained on study. Elacestrant was generally well tolerated, with the most common treatment related adverse events (CTCAE v4.03) being low grade nausea gr1 50% gr2 =19% gr3/4 0% dyspepsia (gr1= 25% gr2 19% gr3/4 0% and dysphagia (gr1 19% gr2 =12% gr3/4 0% Updated analyses with mature data on correlation of FES uptake reduction and tumor response, treatment duration, safety and ESR1 mutation will be presented. Conclusions: Elacestrant significantly reduced FES uptake at both 200 mg and 400 mg doses after 14 days of treatment in heavily pre treated patients with advanced ER+/HER2 breast cancer, including those harboring ESR1 mutations.

However, its intramuscular route of administration may be painful and limits systemic exposure. G1T48 is a highly potent and efficacious oral SERD in both mutant and WT ESR1 preclinical models with the potential to achieve higher exposure and provide clinical benefit in patients with ER+ ABC. Methods Postmenopausal women with ER+/HER2 ABC following progression on endocrine therapy are eligible for this 3 3 dose escalation and expansion study. Patients receive G1T48 QD until disease progression or unacceptable toxicity. The objectives are to evaluate DLTs, safety, tolerability, PK, ER target engagement via [18F] FES PET, and anti tumor efficacy, and to determine the recommended phase 2 dose. Results Currently, 11 patients (mean age 64 years) have received G1T48 doses ranging from 200 800 mg QD for up to 7 months. Prior lines (median of 3) included chemotherapy in 45% fulvestrant in 91% and CDK4/6i in 54% of patients.

ER expression and proliferation index Ki 67 were assessed by immunohistochemistry (IHC) The combination of palbociclib CDK 4/6 inhibitor with SAR439859 was tested for its potential synergistic effect on anti tumor activity. Results After repeated SAR439859 oral administration over 4 days, FES tumoral uptake (SUVmean) decreases compared to baseline by 35, 57, and 55% for the 25 mg/kg qd, 12.5 mg/kg bid and 5 mg/kg bid treatment groups, respectively. FES tumor uptake following SAR439859 treatment at different doses correlates with immunohistochemical scoring for ERa expression. No significant difference in FDG uptake is observed after SAR439859 treatments over 3 days. FLT accumulation in tumor is significantly decreased when palbociclib is combined to SAR439859 64% but not different from the group dosed with palbociclib alone 46% The impact on proliferation is corroborated by Ki 67 IHC data for both groups of treatment. Conclusions In our preclinical studies, dose dependent inhibition of FES tumoral uptake confirmed target engagement of SAR439859 to ERa. FES PET thus appears as a relevant imaging biomarker for measuring non invasively the impact of SAR439859 on tumor estrogen receptor occupancy.

The LSZ102 single agent data are presented below; combination data are not discussed. Methods: In the dose escalation phase evaluating single agent LSZ102 (Arm A) pts (age =18 years; ECOG PS 0 1) with histologically confirmed ER+ ABC and progression on endocrine therapy (ET) received LSZ102. The starting dose was 200 mg once daily. The primary objective of Arm A was to characterize the safety and tolerability of LSZ102 and identify a recommended dose for expansion (RDE) Secondary objectives included preliminary antitumor activity and pharmacokinetics (PK) Results: As of January 22, 2018, 57 pts were enrolled to Arm A (LSZ102 200 mg, n=4; 400 mg, n=6; 450 mg fasted, n=15; 450 mg with food, n=6; 600 mg, n=20; 900 mg, n=6) Median age was 60 years, 75% (n=43) of pts had an ECOG PS of 0, 56% (n=32) had received prior fulvestrant, and 58% (n=33) had received prior CDK4/6 inhibitors; median number of prior lines of therapy (all settings) was 6. At data cut off, 48 pts had discontinued treatment, most (n=45, 94% due to disease progression. Dose limiting toxicities across treatment groups included diarrhea (2 pts in the 900 mg group) vomiting (1 pt in the 600 mg group) and AST and ALT elevation (1 pt in the 450 mg with food group) The most common treatment related adverse events (AEs) in the treatment period were diarrhea (60% nausea (56% and vomiting (30% In the treatment period, treatment related grade 3 AEs (12% were infrequent, and there were no such grade 4 events. Six pts (11% required dose reduction due to AEs (nausea, vomiting or diarrhea) 4/6 of the dose reductions occurred at 900 mg. Preliminary PK assessment showed rapid absorption and dose proportional increases in LSZ102 exposure; trough concentrations were above the predicted tumorostatic concentrations at doses of =400 mg. Based on PK results for the 450 mg fasted and fed cohorts, LSZ102 exposure does not appear to be affected by dosing with a regular meal. Evidence of ER modulation by immunohistochemistry was observed in paired baseline and on treatment biopsies. 18F fluoroestradiol positron emission tomography (FES PET) analysis (n=6) demonstrated abrogation of FES PET signal for pts in the 450 mg and 600 mg dose groups. Seventeen pts (29.8% had a best response of stable disease, and 1 pt, who happened to be in the 600 mg group, achieved a partial response. Conclusion: In heavily pretreated pts, LSZ102 was well tolerated, demonstrated antitumor activity, and achieved effective exposure levels based on PK and pharmacodynamics. Food intake did not appear to significantly alter the PK profile of LSZ102. Dose escalation for LSZ102 in combination with ribociclib or alpelisib is ongoing and will be reported in a future analysis.

In response, corporate social responsibility has emerged as an inescapable priority for business leaders in every country. Frequently, though, CSR efforts are counterproductive, for two reasons. First, they pit business against society, when in reality the two are interdependent. Second, they pressure companies to think of corporate social responsibility in generic ways instead of in the way most appropriate to their individual strategies. The fact is, the prevailing approaches to CSR are so disconnected from strategy as to obscure many great opportunities for companies to benefit society. What a terrible waste. If corporations were to analyze their opportunities for social responsibility using the same frameworks that guide their core business choices, they would discover, as Whole Foods Market, Toyota, and Volvo have done, that CSR can be much more than a cost, a constraint, or a charitable deed it can be a potent source of innovation and competitive advantage. In this article, Michael Porter and Mark Kramer propose a fundamentally new way to look at the relationship between business and society that does not treat corporate growth and social welfare as a zero sum game. They introduce a framework that individual companies can use to identify the social consequences of their actions; to discover opportunities to benefit society and themselves by strengthening the competitive context in which they operate; to determine which CSR initiatives they should address; and to find the most effective ways of doing so.

This broader pedagogical approach is constructivism, which provides students with opportunities for 'constructing' their own knowledge and skills through practical experience in real life or modeled activities. In this case, students acquire their knowledge and skills (including skills of communicating in the target language) as a by product of their real life or modeled activities, thus internalizing (appropriating) the knowledge and skills and not just learning them.

Yet, this also becomes a challenge in scholarly literature on English for Specific Purposes (ESP) since research in this field has been somewhat limited, i.e. most commonly it investigates collaborative writing as a way of developing collaboration.

Also neglected in this field of research are the challenges and opportunities that students experience while learning to collaborate during ESP classes. The paper aims at acquiring more in depth insights into the phenomenon of collaboration during ESP classes to facilitate the practice of language educators who can no longer neglect the urgent need to develop collaboration through their classes. The authors of the paper, who were also the designers of ESP tasks, sought to develop collaboration skills by both engaging learners in collaborative tasks and integrating additional measures to address this skill.

Design/methodology/approach Which aspects of modern payment systems could contribute to improve the way of functioning of today's globalized economy? And, which might even threaten the above mentioned instable equilibrium? This survey paper aims, precisely, at giving some preliminary answers to a complex therefore, ongoing debate at scientific as well as banking and political levels. Findings The coexistence of State's money (i.e. \"legal tender\" and cryptocurrencies can have a disciplining effect on central banks. Nevertheless, there are still high risks connected to the introduction of central bank digital currency, which should be by far not considered to be a perfect substitute of current cash. At the same time, cryptocurrencies issued by central banks might be exposed to the drawbacks of cryptocurrencies without benefiting from correspondingly strong advantages. A well governed two tier system to be achieved through innovation in payment infrastructures might be, in turn, more preferable. Regulated competition by new players combined with \"traditional\" deposits and central bank elements remains essential, although central banks should embrace the technologies underlying cryptocurrencies, because risk payment service providers could move to other currency areas considered to be more appealing for buyers and sellers. Research limitations/implications We do not see specific limitations besides the fact that the following is for sure a broad field of scientific research to be covered, which is at the same time at the origin of ongoing developments and findings. Originality and implications of the paper are, instead, not only represented by its conclusions (which highlight the role of traditional payment instruments and stress why the concept of \"money\" still has to have specific features) but also by its approach of recent literature's review combined with equally strong logical analytical insights. Practical implications In the light of these considerations, even the role of traditional payment systems like paper money is by far not outdated or cannot be at this point, at least replaced by central bank digital currencies (whose features based on dematerialization despite being issued and guaranteed by a public authority are very different) Social implications No matter which form it might assume is what differentiates economic from barter transactions. This conclusion is by far not tautological or self evident since the notion of money has historically been a great object of scientific discussion. In the light of increasingly modern payment instruments, there is no question that money and the effectiveness of related monetary policies have to be also explored from a social perspective according to different monetary scenarios, ranging from central bank digital currencies to private currencies and cash restrictions/abolition.

Medical researchers provide the \"mining\" necessary to secure and sustain the authentication log on a private, Ethereum network, in return for privacypreserving, medical metadata in the form of \"transaction fees.\" Our Motivation Approach From fragmented access to comprehensive access Patients interact with a staggering number of health care providers through the course of their lives from pediatrician, to university physician, dentist, employer health plan provider, specialists, and more. At each stage, they leave data scattered across a particular jurisdiction's system [1] This leads to a fragmented data trail and decaying ease of access, as providers often retain primary data stewardship (either via default practices or explicit legal provisions in over 21 states) [2] Our MedRec prototype enables patients with one stop shop access to their medical history across multiple providers: smart contracts on an Ethereum blockchain [2] aggregate data pointers (references to medical records that are stored elsewhere) into \"patient provider relationships.\" These contract data structures 2/27/2017 MedRec: Medical Data Management on the Blockchain PubPub https:/www.pubpub.org/pub/medrec 3/16 are stored on the blockchain and associate references to disparate medical data with ownership and viewership permissions and record retrieval location. This provides an immutable data lifecycle log, enabling later auditing. We include a cryptographic hash of the record in the smart contract to establish a baseline of the original content and thus provide a check against content tampering. The raw medical record content is never stored on the blockchain, but rather kept securely in providers' existing data storage infrastructure. MedRec facilitates reviewing, sharing and posting of new records via a exible user interface, designed to reect best practices from the Blue Button health record competition [1] We abstract away the blockchain technology to focus on usability for the medical record use case. The interface includes a notications system to alert users when a new record has been posted on their behalf or shared with them. From data rigidity to data sharing Interoperability challenges between dierent provider systems pose signicant barriers to eective data sharing. Patients face hurdles in authorizing data exchange (with other consulting physicians or even family members) due to the lack of a common interface or standard system that orchestrates record access across databases [1] MedRec provides streamlined data sharing functionality by updating viewership 2/27/2017 MedRec: Medical Data Management on the Blockchain PubPub https:/www.pubpub.org/pub/medrec 4/16 permissions on the relevant data pointers. With pointers to patient data aggregated in smart contracts on the blockchain, we can oer a single, common interface where patients chose when, and with whom, they share their data. From obscurity to clarity While most valuable to the patient and provider, medical records also prove critical for research. A recent report from the Oce of the National Coordinator for Health Information Technology emphasizes that biomedical and public health researchers \"require the ability to analyze information from many sources in order to identify public health risks, develop new treatments and cures, and enable precision medicine\" [1] Though some data trickles through to researchers from clinical studies, surveys and teaching hospitals, we note a growing interest among patients, care providers and regulatory bodies to responsibly share more data, and thus enable better care for others [1] With MedRec, we incentivize medical researchers and other healthcare stakeholders to participate in the blockchain network as \"miners\" (see Appendix: Bitcoin Basics for more on mining and the fundamentals of blockchain) These researchers can now obtain greater clarity in their investigations by earning census level, anonymized metadata in return for contributing the computational resources that sustain the network. MedRec enables the emergence of data economics between data consumer and data producer, as 2/27/2017 MedRec: Medical Data Management on the Blockchain PubPub https:/www.pubpub.org/pub/medrec 5/16 the system supplies big data to empower researchers while engaging patients and providers in the choice of how much metadata to release. Designing for patient agency When designing new systems to overcome current EMR challenges, we must prioritize patient agency. Patients benet from a holistic, transparent view of their medical history, and in the age of online banking and social media, patients are increasingly willing, able and desirous of managing their data on the web and on the go [4] MedRec restores patient agency by empowering users with a focal point for access and review of their medical history, and an easy mechanism for sharing their data across medical jurisdictions. Patients can authorize a new doctor to review their record and obtain a second opinion, or grant viewership rights to a guardian they trust. Grandparents can seamlessly share medical data with their families, to reduce the mystery of family health history. Furthermore, the authorization log persists in the distributed network, providing crucial back up and restore functionality. Patients can leave and rejoin the system multiple times, for arbitrary periods, and regain access to their history by downloading the latest blockchain from the network.

No standardized surgical treatment guideline was available, and the performance varies for each patient. INTERVENTIONS We performed a robotic assisted reconstruction of the cervix and vagina using an SIS graft (Cook Medical, Bloomington, IN) and fusion of the hemiuterus for a 12 year old girl from China diagnosed with congenital vaginal and cervical atresia (U4C4V4) She complained of severe abdominal periodic pain for 2 months. Mammary development and her serum sex hormone were within normal range. The patient has a single kidney. The diagnosis was made according to clinical characteristics, physical examination, and magnetic resonance imaging and classified using the European Society of Human Reproduction and Embryology /European Society for Gynaecological Endoscopy (ESHRE/ESGE) system. There was a hematometra of 7 cm diameter in her pelvis. We constructed a novel vagina by sharp and blunt separation and connected it to the uterine cavity. With the SIS graft, we reconstructed her cervix and vagina, and we fused the hemiuterus to make the uterine cavity spacious. The operating time was 260 minutes, and blood loss was 300 mL. She recovered well after the operation without any complications. After surgery, the patient has had normal menstruation without pain. She insists on wearing the vaginal mold 24 hours per day.

OBJECTIVES To examine three methods to assess occurrence of a goals of care discussion patient report, clinician report, and documentation in the electronic health record (EHR) at a clinic visit for seriously ill patients and determine whether each method is associated with patient reported receipt of goal concordant care. METHODS We conducted a secondary analysis of a multicenter cluster randomized trial, with 494 patients and 124 clinicians caring for them. Self reported surveys collected from patients and clinicians two weeks after a clinic visit assessed occurrence of a goals of care discussion. Documentation of a goals of care discussion was abstracted from the EHR. Patient reported receipt of goal concordant care was assessed by survey two weeks after the visit. RESULTS Fifty two percent of patients reported occurrence of a goals of care discussion at the clinic visit; clinicians reported occurrence of a discussion at 66% of visits. EHR documentation occurred in 42% of visits (P 0.001 for each compared with other two) Patients who reported occurrence of a goals of care discussion at the visit were more likely to report receipt of goal concordant care than patients who reported no discussion (b 0.441, 95% CI 0.190 0.692; P 0.001) Neither occurrence of a discussion by clinician report nor by EHR documentation was associated with goal concordant care.

It is unclear how goals of care discussions should occur. The objective of the study was to determine which patients could benefit, requirements, content, documentation, and harms and benefits of emergency medicine goals of care discussions. We sought primary evidence on goals of care discussions in EDs with adult patients nearing end of life, published in English after 1989. Data sources included Medline, Embase, PsycINFO, CINAHL, Web of Science and reference lists of included articles. One thousand nine hundred and twenty abstracts were screened, five articles selected. There was no consensus on the meaning of goals of care, which is often confused with advanced care planning and treatment limitation. Emergency clinicians can identify most patients needing discussions following training. There was no evidence for how to involve stakeholders, nor how to adapt conversations to meet cultural and linguistically diverse needs. Expert panels have suggested requirements and content for conversations with little supporting evidence. There was no evidence for how emergency conversations differ to those in other settings, nor for harms or benefits for holding goals of care conversations in EDs. Increased ED goals of care conversations increased hospice referral and reduced in patient admissions.

The phrase is of particular importance when it is used to refer to a certain kind of conversation between a clinician and patient (or family) often called a \"goals of care discussion.\" Sometimes the need for such a discussion is a clinician's shorthand way of indicating it is time to clarify a patient's code status or shift the focus of care to palliation. At other times, goals of care discussions refer to the need for a specific approach to conversation about a more general plan of care. For instance, one task force recommends that goals of care discussions in serious illness should address not only prognosis and goals, but also decision making preferences, family involvement, fears, function, and tradeoffs. Others suggest that goals of care discussions should help patients' establish \"agreed on, desired health expectations that are appropriate, documented and communicated,\" that these conversations should clarify patients' values, goals, and priorities in light of information about their diagnosis, prognosis, and treatment options, or that these conversations should include a leading emphasis on the decision that needs to be made and the likelihoods of different possible outcomes regarding survival, symptoms, and functional ability. Such differences in approach are reflected in another recent review that assessed elements of goals of care discussions and their operationalization and concluded that consensus is lacking on the question of content. Moreover, some authors suggest these discussions may be less about goals directed at treatment decisions, and more about emotional issues, management of symptoms, and rapport building. In defense of such diversity, we can accept the need for flexibility in the content of goals of care discussions given the many differences among patients, their conditions, and their circumstances. But we also do well to consider the content that should form the consistent core of these conversations when significant clinical decisions need to be made especially when we are trying to explain and model for trainees practices that are clinically meaningful and feasible within the demands of clinical practice. To this end, based on literature and experience, I suggest the core content of goals of care discussions should include diagnosis, prognosis, goals of care, treatment or test, burdens of treatment or test, and probabilities of outcomeswith or without treatment or test (Fig. 1) These are key dimensions of decision making we need to comprehend and remember to communicate so that shared decision making with patients is facilitated by shared understanding. Not surprisingly, these dimensions have much in common with elements of informed consent. By making the patient's most important goals of care the conversational focal point, decision making is patient centered, purpose oriented, and premised on the patient's beliefs, values, priorities, preferences, and circumstances. Specific goals of care can be elicited by open ended and closedended questions regarding goals, expectations, or hopes. For many patients, preferred goals of care will fall within one of the following categories: cure, live longer, improve or maintain function, comfort, achieve life goals, or provide support for family. The core content I suggest endeavors to capture what is most essential and feasible in other approaches, and to keep goals at the center of goals of care discussions. This content is fundamental enough to be consistent with the risks, benefits, and likelihoods of informed consent discussions. As a clinician and teacher, I believe this approach satisfies the need for a clinically practical way to articulate (and sometimes even diagram in front of patients) the dimensions that guide reasoning about decisions, and to communicate that these different dimensions are inter related and therefore need to be taken together. One of the hallmarks of a successful goals of care discussion is that it allows everyone to take a step back from the intense focus on a specific intervention (such as cardiopulmonary resuscitation) by considering the broader purpose and context of that intervention. While interventionoriented decision making tends to focus on the most readily available means of addressing the most immediate medical problem, goal oriented discussions take a larger, longer view. Framed by goals of care, conversation about decision making moves the question from \"Would you like us to do this, or not?\" to \"Will this help us achieve your goals of care, or not?\" In this way, goal oriented decision making draws our attention Received September 20, 2019 Accepted October 25, 2019 35(3):913 5", "corpus_id": 207948802, "venue": "Journal of General Internal Medicine", "year": 2019, "author_names": [ "Lauris C Kaldjian" ], "n_citations": 2, "n_key_citations": 0, "score": 3 }, { "doc_id": "44107351", "title": "Effect of a Patient and Clinician Communication Priming Intervention on Patient Reported Goals of Care Discussions Between Patients With Serious Illness and Clinicians: A Randomized Clinical Trial", "abstract": "Importance Clinician communication about goals of care is associated with improved patient outcomes and reduced intensity of end of life care, but it is unclear whether interventions can improve this communication. Objective To evaluate the efficacy of a patient specific preconversation communication priming intervention (Jumpstart Tips) targeting both patients and clinicians and designed to increase goals of care conversations compared with usual care. Design, Setting, and Participants Multicenter cluster randomized trial in outpatient clinics with physicians or nurse practitioners and patients with serious illness. The study was conducted between 2012 and 2016. Interventions Clinicians were randomized to the bilateral, preconversation, communication priming intervention (n 65) or usual care (n 67) with 249 patients assigned to the intervention and 288 to usual care. Main Outcomes and Measures The primary outcome was patient reported occurrence of a goals of care conversation during a target outpatient visit. Secondary outcomes included clinician documentation of a goals of care conversation in the medical record and patient reported quality of communication (Quality of Communication questionnaire [QOC] 4 indicator latent construct) at 2 weeks, as well as patient assessments of goal concordant care at 3 months and patient reported symptoms of depression (8 item Patient Health Questionnaire; PHQ 8) and anxiety (7 item Generalized Anxiety Disorder survey; GAD 7) at 3 and 6 months.

OBJECTIVES To describe the development of the 3 Act Model curriculum and to assess its impact on the GOC communication skills of IM interns. METHODS The curriculum was developed with input from multidisciplinary experts, IM residents, and patient/family representative. Notable elements included instrument development with validity evidence established, determination of proficiency standards, and creation of role play scenarios. In two 3 hour workshops, interns participated in role plays as both providers and patients, before and after teaching (which included narrative reflection, didactics, and video demonstration) RESULTS 22 interns played the role of provider in 5 unique scenarios; 106 proficiency ratings were analyzable. Interns objectively rated as proficient increased from 30% (pre test) to 100% (final role play) By the end of the training, 96% of interns strongly agreed or agreed that they felt ready to independently lead basic GOC discussions, and the percentage who strongly agreed increased with successive role plays.

However, since little attention has been given to the impact of GaaP on public value creation more research is needed to analyse whether the GaaP is effective to help the government to deliver public services that fulfil social expectations and, hence, public value. Indeed, efficiency does not guarantee public value. Besides efficiency, public value incorporates citizens' variegated expectations and needs that change over time and that are sometimes rival. For these reasons, the delivery of public value is often challenging for public agencies. The aim of this paper is to explain how the GaaP configuration can help public administration to deliver public value better. The paper finds that the modularity of the platform configuration and different ecosystems that support public agencies need to be orchestrated to support the effective creation of public value.

However, drawbacks of conditioning with Fenton's reagent are requirement of acidic conditions to prevent iron precipitation and subsequent neutralization with alkaline additive to obtain the pH of the filtrate close to neutrality. In this study, roles of pH were thoroughly investigated in the acidification pretreatment, Fenton reaction, and the final filtrate after conditioning. Through the response surface methodology (RSM) the optimal dosages of H2SO4, Fe(2+ H2O2, and lime acted as a neutralizer were found to be 0 (no acidification) 47.9, 34.3 and 43.2 mg/g DS (dry solids) With those optimal doses, water content of the dewatered sludge cakes could be reduced to 55.8 0.6 wt% and pH of the final filtrate was 6.6 0.2. Fenton conditioning without initial acidification can simplify the conditioning process and reduce the usage of lime. The Fe(3+ content in the sludge cakes showed a close correlation with the dewaterability of conditioned sludge, i.e. the water content of sludge cakes, SRF (specific resistance to filtration) CST (capillary suction time) bound water content, and specific surface area. It indicated that the coagulation by Fe(3+ species in Fenton reaction could play an important role, compared to traditional Fenton oxidation effect on sludge conditioning. Thus, a two step mechanism of Fenton oxidation and Fe(III) coagulation was proposed in sewage sludge conditioning. The mechanisms include the following: (1) extracellular polymeric substances (EPS) were firstly degraded into dissolved organics by Fenton oxidation; (2) bound water was converted to free water due to degradation of EPS; (3) the sludge particles were disintegrated into small ones by oxidation; (4) Fe(3+ generated from Fenton reaction acted as a coagulant to agglomerate smaller sludge particles into larger dense particles with less bond water; (5) finally, the dewatered sludge cakes were obtained, with less small pores (1 10 nm) that contributed to water affinity, but with more large pores >10 nm) that contributed to a permeable, rigid lattice structure.

Bukhvalov Description of the goal, tasks and main results In this paper, the author pays special attention to the model developed by Mayers (1972) who challenged the assumption of marketability of all assets by introducing the effect of 5 nonmarketable assets. Mayers examined the role of returns to human capital as a proxy for nonmarketable asset. Mayers' extended model suggests that since any individual investor's human capital is unique, the covariance between the market portfolio and payoffs to human capital will have an impact on the optimal weight of the market portfolio, therefore, the covariance explains why investors hold different portfolios in reality. This research aims to understand whether the CAPM with nonmarketable assets has meaningful implications in the Russian market. The following objectives are met to realize the ultimate goal of the paper: 1. Theoretical and empirical background of the traditional Capital Asset Pricing Model are covered; 2. Theoretical and empirical background of the CAPM model with nonmarketable assets are covered; 3. Methodologies for the calculation of differences between the Mayers and SLM risk measures are derived; 4. The data on 50 most liquid stocks of Russia's largest companies is obtained. The companies are further segmented into 10 different sectors of economy to precisely evaluate the effect of returns to human capital on different classes of assets; 5. Regressions are run to estimate risk measures for respective classes of assets; 6. Differences between the Mayers and SLM risk measures are calculated to check whether this differences lead to significant deviations in final estimations of the required returns on risky assets in Russia; 7. Interpretation of results and limitations of the approach are elaborated. Contrary to the SLM model, the expanded model implies that not all maximizing investors hold the identical (except for scale) portfolio of marketable assets. It implies that each investor holds a portfolio of marketable assets that solves his personal (and possibly unique) portfolio problem and, therefore, allows investors to maintain unique portfolios. Empirical analysis of the CAPM with nonmarketable assets has shown significant difference of the estimates of the models for Innovations sectors. The beta predicted by extended model is 9.2% higher than the SLM 6 beta. Unfortunately, the research has failed to prove the validity of the model for other sectors of companies and for the market in general, which may be attributable to the limitations stated in the paper. These limitations include: 1) the quarrels about the way to define human capital, 2) the controversy of using human capital as a proxy, and 3) the imperfection of data on Russian stock market.", "corpus_id": 55474410, "venue": "", "year": 2016, "author_names": [ "Bokuchava Lasha Zurabovich", "Bokuchava Lasha" ], "n_citations": 69, "n_key_citations": 6, "score": 0 }, { "doc_id": "154027593", "title": "Does Integrated Reporting Matter to the Capital Market?", "abstract": "Integrated reporting (IR) is an emerging international corporate reporting initiative arising to address, inter alia, the limitations of the current corporate reporting suite which are commonly criticized for being both voluminous and disjointed.

Immune activation may direct the immune response, thus conferring tolerance to allergens such as animal dander or tree and grass pollen. METHODS Parents of children who were 6 to 13 years of age and were living in rural areas of Germany, Austria, or Switzerland where there were both farming and nonfarming households completed a standardized questionnaire on asthma and hay fever. Blood samples were obtained from the children and tested for atopic sensitization; peripheral blood leukocytes were also harvested from the samples for testing. The levels of endotoxin in the bedding used by these children were examined in relation to clinical findings and to the cytokine production profiles of peripheral blood leukocytes that had been stimulated with lipopolysaccharide and staphylococcal enterotoxin B. Complete data were available for 812 children. RESULTS Endotoxin levels in samples of dust from the child's mattress were inversely related to the occurrence of hay fever, atopic asthma, and atopic sensitization. Nonatopic wheeze was not significantly associated with the endotoxin level. Cytokine production by leukocytes (production of tumor necrosis factor alpha, interferon gamma, interleukin 10, and interleukin 12) was inversely related to the endotoxin level in the bedding, indicating a marked down regulation of immune responses in exposed children.

Methods Patients with COVID 19 admitted to Tongji Hospital from January 26, 2020 to February 5, 2020 were retrospectively enrolled and followed up until March 3, 2020. Potential risk factors for severe COVID 19 were analyzed by a multivariable binary logistic model. Cox proportional hazard regression model was used for survival analysis in severe patients. Results We identified 269 (49.1% of 548 patients as severe cases on admission. Elder age, underlying hypertension, high cytokine levels (IL 2R, IL 6, IL 10, and TNF a) and high LDH level were significantly associated with severe COVID 19 on admission. The prevalence of asthma in COVID 19 patients was 0.9% markedly lower than that in the adult population of Wuhan. The estimated mortality was 1.1% in nonsevere patients and 32.5% in severe cases during the average 32 days of follow up period.

We evaluated the safety and efficacy of SB010, a novel DNA enzyme (DNAzyme) that is able to cleave and inactivate GATA3 messenger RNA (mRNA) METHODS We conducted a randomized, double blind, placebo controlled, multicenter clinical trial of SB010 involving patients who had allergic asthma with sputum eosinophilia and who also had biphasic early and late asthmatic responses after laboratory based allergen provocation. A total of 40 patients could be evaluated; 21 were assigned to receive 10 mg of SB010, and 19 were assigned to receive placebo, with each study drug administered by means of inhalation once daily for 28 days. An allergen challenge was performed before and after the 28 day period. The primary end point was the late asthmatic response as quantified by the change in the area under the curve (AUC) for forced expiratory volume in 1 second (FEV1) RESULTS After 28 days, SB010 attenuated the mean late asthmatic response by 34% as compared with the baseline response, according to the AUC for FEV1, whereas placebo was associated with a 1% increase in the AUC for FEV1 (P=0.02) The early asthmatic response with SB010 was attenuated by 11% as measured by the AUC for FEV1, whereas the early response with placebo was increased by 10% (P=0.03) Inhibition of the late asthmatic response by SB010 was associated with attenuation of allergen induced sputum eosinophilia and with lower levels of tryptase in sputum and lower plasma levels of interleukin 5. Allergen induced levels of fractional exhaled nitric oxide and airway hyperresponsiveness to methacholine were not affected by either SB010 or placebo.

This paper focuses on interfacial resistance between the cathode layer (CL) and the current collector (CC) observed at high frequencies, which is generally attributed to a resistance of surface film like SEI. To investigate the interfacial resistance systematically, different interfaces between the CL and the CC were prepared by controlling the press rate for the cathode preparation, or by introducing a carbon under coating layer (CUL) followed by electrochemical impedance spectroscopy (EIS) The interfacial resistance between the CL and the CC prepared with an insufficient press rate or without a CUL was extremely high for the entire cathode. From the cathode cross sectional observation, it was observed that this high interfacial resistance was caused by low contact rate at the interface. Using a pouch type symmetric cell, EIS revealed that the interfacial resistance is attributed to electric resistance, that is, contact resistance at the interface.

Indeed, many commentators interpret the steep upward trend during the late 1990s and early 2000s in accounting misstatements by companies with Big Five auditors as almost conclusive evidence that their assurance services have deteriorated over time (e.g. Coffee 2002; Imhoff 2003; Zeff 2003) Measuring trends in absolute audit quality is typically infeasible, so we more narrowly focus on discriminating between the relative performance of the Big Five and non Big Five audit firms in preventing companies from orchestrating accounting fraud.

Lessons from the Credit Card Wars", "abstract": "Partisans on one side of the class action debates argue that the class device is a critical enforcement tool that increases much needed access to justice. Combatants on the other side scoff that class actions are tools for shaking down corporations for settlement payments and attorneys' fees in unmeritorious cases. In his most recent book, Entrepreneurial Litigation: Its Rise, Fall and Future, John C. Coffee puts both sides in their place, providing an account that, he aptly tells us, \"has long been missing in the literature, in large part because academics writing in this area either have been so ideologically committed to the private attorney general concept or so implacably opposed to it\" that they've failed to fully examine its consequences. If it is a virtue of the class device that it can aggregate a large number of small interests and that surely is a virtue for Coffee then a corresponding detriment is that the named plaintiffs' interests are too small to warrant any substantial investment in monitoring the lawyers. And for Coffee, the predictable result is what he terms \"abusive litigation\" the attempt by lawyers to leverage the scale of class cases to coerce unwarranted settlements. Reform, according to Coffee, \"requires that the merits need to matter more.\" To ensure that plaintiffs' counsel make investment decisions based on case merit, rather than exploitable cost asymmetries, Coffee would have lawyers assume a measure of financial responsibility for the fees and expenses incurred in unmeritorious actions. This book review assumes that Professor Coffee's proposals would solve the \"abusive litigation problem,\" and then examines, in this hypothetical post reform world, how we really regard the private attorney general model that is at the core of class actions. The inquiry focuses on consequential class cases that seek structural institutional reform through injunctive relief, because it is mandatory non opt out class claims under Rule 23(b)(2) that bring into starkest relief concerns about the assumption of power by private actors. And the ongoing Payment Card class actions brought by merchants against Visa, MasterCard and American Express (the author's extraordinary personal connection to which is disclosed in the essay) form an almost perfect laboratory for examining these issues. This essay explores concerns with self nominated class counsel assuming public functions including, for example, the negotiation of rules that bind entire industries and the prosecution of cases that public enforcers have affirmatively elected not to pursue. And centrally, this essay investigates the unease that the traditional bar and commentariat feel with the on the ground, actual practice of complex class litigation. We are afforded a rare backstage pass to observe these practices because of the extraordinary fact that a Willkie Farr partner was arrested for perpetrating an unrelated fraud upon her client, MasterCard, leading to the disclosure of thousands of emails, including many with plaintiffs' lead counsel in the Amex case. And the reactions of all concerned to those unvarnished communications illustrate a high impact collision of realism and formalism. The realist, emblemized by John Coffee, asks what the entrepreneurial lawyer actually does and why and, in this case, would find a lawyer intent on achieving industrial reform for his clients, practicing all the politics and diplomacy necessary to get there. The formalist, embodied here by the district judge in the Amex case, relies on ex ante rules and precepts regarding proper lawyer comportment, in order to obviate nettlesome ex post inquiry into whether the attorney has indeed rendered loyal and able service to his principal. Professor Coffee may yet solve the abusive litigation problem. But even so, deep skepticism of the private attorney general model born of long experience with abusive litigation will surely persist, vestigial, like a phantom limb.", "corpus_id": 73669245, "venue": "", "year": 2015, "author_names": [ "Myriam E Gilles" ], "n_citations": 0, "n_key_citations": 0, "score": 0 }, { "doc_id": "154644137", "title": "A Theory of Corporate Scandals: Why the U.S. And Europe Differ", "abstract": "A wave of financial irregularity in the USA in 2001 2 culminated in the Sarbanes Oxley Act. A worldwide stockmarket bubble burst over this same period, with the actual market decline being proportionately more severe in Europe. Yet, no corresponding wave of financial scandals involving a similar level of companies occurred in Europe. Given the higher level of public and private enforcement in the USA for securities fraud, this contrast seems perplexing. This paper submits that different kinds of scandals characterize different systems of corporate governance. In particular, dispersed ownership systems of governance are prone to the forms of earnings management that erupted in the USA, but concentrated ownership systems are much less vulnerable. Instead, the characteristic scandal in such systems is the appropriation of private benefits of control. This paper suggests that this difference in the likely source of, and motive for, financial misconduct has implications both for the utility of gatekeepers as reputational intermediaries and for design of legal controls to protect public shareholders. The difficulty in achieving auditor independence in a corporation with a controlling shareholder may also imply that minority shareholders in concentrated ownership economies should directly select their own gatekeepers.

Conclusions were made through discussion within the group. Introduction The story of WorldCom started with a plan on how to create a long distance telephone service provider, sketched on a napkin in a coffee shop back in 1983. The company started out as Long Distance Discount Service (LDDS) the following year, and grew through acquisitions and mergers into United State's second largest long distance telephone company by the end of the 20th century. With a worldwide presence it seemed poised to become one of the world largest telecommunications corporations. Instead, it filed the largest bankruptcy, of some $79.5bn, in the U.S. history at the time. The question is then how could this happen and why did it happen? There are of course several key factors leading up to the huge amount of money filed in the bankruptcy, and these will be discussed here. From Nothing to Everything It all started back in 1984 when the LDDS was founded, in the following year, the CEO up to the bankruptcy, Mr Bernhard Ebbers was appointed. [1] Described as likable and colorful by supporters and greedy and incompetent by others [2] he will play part of the upcoming ruin of WorldCom. But at the time he helped LDDS grow into a huge worldwide renowned company, renamed to WorldCom in the early 1990's. He managed this by pursuing an aggressive policy of mergers and acquisitions. The 1990's were a time of growth and immense expansion in many areas, but especially the telephone and internet traffic, which were the main areas of focus for WorldCom. A capacity planner at WorldCom, Tom Stluka, created a model to predict the growth of the traffic handled by WorldCom. However, his model was a best case scenario, which suggested that the total internet traffic would double every 100 days. For reasons unknown, this model ended up at top of the company, and they chose to believe in the model. Therefore WorldCom went through with not less than 65 acquisitions and mergers during a seven year period from 1991 to 1997. These deals cost WorldCom almost $60 billion, and at the same time, accumulating a debt of $41 billion. [3] These sums are huge, and in order to live through these kinds of investments there has to be a good coordination and integration between new parts and old parts of the company this was not the case at WorldCom. Instead of actually integrating the assets, so expensively purchased, profit was created through sketchy bookkeeping and accounting fraud. This will be covered more extensively shortly, but first a short digression about the relation between Mr. Ebbers and a telecommunication analyst at the brokerage Solomon Smith Barney,", "corpus_id": 14586491, "venue": "", "year": 2012, "author_names": [ "Daniel Pettersson", "Zoran Maracic" ], "n_citations": 0, "n_key_citations": 0, "score": 0 }, { "doc_id": "167451728", "title": "Reforming the Securities Class Action: An Essay on Deterrence and its Implementation", "abstract": "The securities class action cannot be justified in terms of compensation, but only in terms of deterrence. Currently, the damages recovered through private enforcement dwarf the financial penalties levied by public enforcement. Yet, the evidence is clear that corporate officers and insiders rarely contribute to securities class action settlements, with the settlement funds coming instead from the corporation and its insurers. As a result, the cost of such actions in the aggregate falls on largely diversified shareholders. Such a system is akin to punishing the victims of burglary for their negligence in suffering a burglary and does little to deter corporate officials who have private motives for engaging in securities fraud. The present structure of securities class actions benefits a trio of interest groups corporate officials, plaintiff's attorneys, and insurers but not shareholders. To reform the securities class action and give it a true deterrent orientation, this article proposes a variety of steps none requiring legislation or the reversal of well established precedents to shift the costs of the securities class action to the culpable. These steps proceed from the twin premises that (1) the settlement of a securities class action is a conflict of interest transaction requiring independent directors to exercise oversight over the allocation process, and (2) enterprise liability is an ineffective approach for misconduct that is privately motivated and easily concealed.

Despite its potential advantageous effects on learning, little is known about its actual effects on students' learning from students' and educators' perspectives. OBJECTIVES To understand students' learning through small group work from the perspectives of students and educators. DESIGN A qualitative study with focus group interviews was carried out. METHODS Semi structured interviews with open ended questions were performed with 13 undergraduate nursing students and 10 educators. RESULTS Four main themes, \"initiative learning\" \"empowerment of interactive group dynamics\" \"factors for creating effective learning environment\" and \"barriers influencing students' learning\" were derived regarding students' learning in small group work based on the perspectives of the participants. The results showed the importance of learning attitudes of students in individual and group learning. Factors for creating an effective learning environment, including preference for forming groups, effective group size, and adequacy of discussion, facilitate students' learning with the enhancement of learning engagement in small group work. The identified barriers, such as \"excessive group work\" \"conflicts\" and \"passive team members\" can reduce students' motivation and enjoyment of learning. CONCLUSION Small group work is recognized as an effective teaching method for knowledge enhancement and skill development in nursing education. All identified themes are important to understand the initiatives of students and group learning, factors influencing an effective learning environment, and barriers hindering students' learning.

To address this knowledge gap, we collected data on three design features thought to be distinctive of CUREs (discovery, iteration, collaboration) and on students' levels of ownership and career intentions from ~800 undergraduates who had completed CURE or inquiry courses, including courses from the Freshman Research Initiative (FRI) which has a demonstrated positive effect on student retention in college and in science, technology, engineering, and mathematics. We used structural equation modeling to test relationships among the design features and student ownership and career intentions. We found that discovery, iteration, and collaboration had small but significant effects on students' intentions; these effects were fully mediated by student ownership. Students in FRI courses reported significantly higher levels of discovery, iteration, and ownership than students in other CUREs.

Findings regarding the influence of student interactions on learning were derived using a variety of data collection methodologies, including quantitative data used to test the effectiveness of various interactive procedures and qualitative analyses of verbal protocols to better understand the interactive dynamics involved in such learning devices. The ISA work highlights the complementary value of both of these methodological approaches for studying group work effects. ISA findings suggest that PE teachers prepare students for functional interaction group work by taking into consideration the students' characteristics (like gender or desire for control) in the constitution of dyads and then effectively training the tutors to deliver the expected content.

Methods In this retrospective, multicentre cohort study, we included all adult inpatients =18 years old) with laboratory confirmed COVID 19 from Jinyintan Hospital and Wuhan Pulmonary Hospital (Wuhan, China) who had been discharged or had died by Jan 31, 2020. Demographic, clinical, treatment, and laboratory data, including serial samples for viral RNA detection, were extracted from electronic medical records and compared between survivors and non survivors. We used univariable and multivariable logistic regression methods to explore the risk factors associated with in hospital death. Findings 191 patients (135 from Jinyintan Hospital and 56 from Wuhan Pulmonary Hospital) were included in this study, of whom 137 were discharged and 54 died in hospital. 91 (48% patients had a comorbidity, with hypertension being the most common (58 [30% patients) followed by diabetes (36 [19% patients) and coronary heart disease (15 [8% patients) Multivariable regression showed increasing odds of in hospital death associated with older age (odds ratio 1*10, 95% CI 1*03 1*17, per year increase; p=0*0043) higher Sequential Organ Failure Assessment (SOFA) score (5*65, 2*61 12*23; p<0*0001) and d dimer greater than 1 mg/mL (18*42, 2*64 128*55; p=0*0033) on admission. Median duration of viral shedding was 20*0 days (IQR 17*0 24*0) in survivors, but SARS CoV 2 was detectable until death in non survivors. The longest observed duration of viral shedding in survivors was 37 days. Interpretation The potential risk factors of older age, high SOFA score, and d dimer greater than 1 mg/mL could help clinicians to identify patients with poor prognosis at an early stage. Prolonged viral shedding provides the rationale for a strategy of isolation of infected patients and optimal antiviral interventions in the future.

The data will be used for future reference. Methods: From 31 January to 2 February 2020, we conducted an online survey using snowball sampling techniques. The online survey collected information on demographic data, physical symptoms in the past 14 days, contact history with COVID 19, knowledge and concerns about COVID 19, precautionary measures against COVID 19, and additional information required with respect to COVID 19. Psychological impact was assessed by the Impact of Event Scale Revised (IES R) and mental health status was assessed by the Depression, Anxiety and Stress Scale (DASS 21) Results: This study included 1210 respondents from 194 cities in China. In total, 53.8% of respondents rated the psychological impact of the outbreak as moderate or severe; 16.5% reported moderate to severe depressive symptoms; 28.8% reported moderate to severe anxiety symptoms; and 8.1% reported moderate to severe stress levels.

There is limited support for many of its key epidemiologic features, including the incubation period for clinical disease (coronavirus disease 2019 [COVID 19] which has important implications for surveillance and control activities. Objective: To estimate the length of the incubation period of COVID 19 and describe its public health implications. Design: Pooled analysis of confirmed COVID 19 cases reported between 4 January 2020 and 24 February 2020. Setting: News reports and press releases from 50 provinces, regions, and countries outside Wuhan, Hubei province, China. Participants: Persons with confirmed SARS CoV 2 infection outside Hubei province, China. Measurements: Patient demographic characteristics and dates and times of possible exposure, symptom onset, fever onset, and hospitalization. Results: There were 181 confirmed cases with identifiable exposure and symptom onset windows to estimate the incubation period of COVID 19. The median incubation period was estimated to be 5.1 days (95% CI, 4.5 to 5.8 days) and 97.5% of those who develop symptoms will do so within 11.5 days (CI, 8.2 to 15.6 days) of infection. These estimates imply that, under conservative assumptions, 101 out of every 10 000 cases (99th percentile, 482) will develop symptoms after 14 days of active monitoring or quarantine. Limitation: Publicly reported cases may overrepresent severe cases, the incubation period for which may differ from that of mild cases. Conclusion: This work provides additional evidence for a median incubation period for COVID 19 of approximately 5 days, similar to SARS. Our results support current proposals for the length of quarantine or active monitoring of persons potentially exposed to SARS CoV 2, although longer monitoring periods might be justified in extreme cases.

The fundamental reason for a Muslim to be radical is because of feelings of isolation from politics and a feeling of gaining great injustice committed by the West. This caused hatred towards the West. It is also important to note that Indonesia's radical movement originated from the reform movement in the Middle East. The fall of Suharto in 1998 continued with the Reformation period which did not imply further political restrictions on the establishment of radically inspired Muslim organizations. Even so, radical Islamic based political parties did not get a significant number of votes, thus forcing radicals to use extreme tactics to try to make a difference. Extreme actions by radicals are carried out with bomb terror to achieve their political goals. This paper uses a descriptive qualitative approach as the main writing approach, and uses the soft power theory approach by Joseph Nye, that the most common forms of soft power employed daily include basic diplomacy, information efforts (including public diplomacy) and intelligence (Forest, 2007) The results of this study are: (1) Government policy makers need to understand the boundaries of public diplomacy, use efficient feedback mechanisms to assess the impact of certain policies, build and encourage forums to interact with community groups, frame important issues about radicalism in a more constructive way, and carry out reforms in the education sector especially where networks of radicalism are rooted; (2) An effective public diplomacy agenda requires a commitment to educate the public to understand radicalism and responsible communication, and to motivate grassroots community campaigns to develop and disseminate effective anti radicalism messages; and (3) It is very clear that intelligence plays an important role in effective strategies and tactics to determine where, when and how to apply hard power and soft power in responding to terrorist threats, and accurate and strong international cooperation in intelligence collection and analysis is needed to deal with the movement of radical clandestine groups that have global networks.

We aimed to identify patterns of cannabis use with the strongest effect on odds of psychotic disorder across Europe and explore whether differences in such patterns contribute to variations in the incidence rates of psychotic disorder. Methods We included patients aged 18 64 years who presented to psychiatric services in 11 sites across Europe and Brazil with first episode psychosis and recruited controls representative of the local populations. We applied adjusted logistic regression models to the data to estimate which patterns of cannabis use carried the highest odds for psychotic disorder. Using Europe wide and national data on the expected concentration of D9 tetrahydrocannabinol (THC) in the different types of cannabis available across the sites, we divided the types of cannabis used by participants into two categories: low potency (THC <10% and high potency (THC =10% Assuming causality, we calculated the population attributable fractions (PAFs) for the patterns of cannabis use associated with the highest odds of psychosis and the correlation between such patterns and the incidence rates for psychotic disorder across the study sites. Findings Between May 1, 2010, and April 1, 2015, we obtained data from 901 patients with first episode psychosis across 11 sites and 1237 population controls from those same sites. Daily cannabis use was associated with increased odds of psychotic disorder compared with never users (adjusted odds ratio [OR] 3*2, 95% CI 2*2 4*1) increasing to nearly five times increased odds for daily use of high potency types of cannabis (4*8, 2*5 6*3) The PAFs calculated indicated that if high potency cannabis were no longer available, 12*2% (95% CI 3*0 16*1) of cases of first episode psychosis could be prevented across the 11 sites, rising to 30*3% (15*2 40*0) in London and 50*3% (27*4 66*0) in Amsterdam. The adjusted incident rates for psychotic disorder were positively correlated with the prevalence in controls across the 11 sites of use of high potency cannabis (r 0*7; p=0*0286) and daily use (r 0*8; p=0*0109) Interpretation Differences in frequency of daily cannabis use and in use of high potency cannabis contributed to the striking variation in the incidence of psychotic disorder across the 11 studied sites. Given the increasing availability of high potency cannabis, this has important implications for public health.

While the impact of adolescent cannabis use on the development of psychosis has been investigated in depth, little is known about the impact of cannabis use on mood and suicidality in young adulthood. Objective To provide a summary estimate of the extent to which cannabis use during adolescence is associated with the risk of developing subsequent major depression, anxiety, and suicidal behavior. Data Sources Medline, Embase, CINAHL, PsycInfo, and Proquest Dissertations and Theses were searched from inception to January 2017. Study Selection Longitudinal and prospective studies, assessing cannabis use in adolescents younger than 18 years (at least 1 assessment point) and then ascertaining development of depression in young adulthood (age 18 to 32 years) were selected, and odds ratios (OR) adjusted for the presence of baseline depression and/or anxiety and/or suicidality were extracted. Data Extraction and Synthesis Study quality was assessed using the Research Triangle Institute item bank on risk of bias and precision of observational studies. Two reviewers conducted all review stages independently. Selected data were pooled using random effects meta analysis. Main Outcomes and Measures The studies assessing cannabis use and depression at different points from adolescence to young adulthood and reporting the corresponding OR were included. In the studies selected, depression was diagnosed according to the third or fourth editions of Diagnostic and Statistical Manual of Mental Disorders or by using scales with predetermined cutoff points. Results After screening 3142 articles, 269 articles were selected for full text review, 35 were selected for further review, and 11 studies comprising 23 317 individuals were included in the quantitative analysis. The OR of developing depression for cannabis users in young adulthood compared with nonusers was 1.37 (95% CI, 1.16 1.62; I2 0% The pooled OR for anxiety was not statistically significant: 1.18 (95% CI, 0.84 1.67; I2 42% The pooled OR for suicidal ideation was 1.50 (95% CI, 1.11 2.03; I2 0% and for suicidal attempt was 3.46 (95% CI, 1.53 7.84, I2 61.3% Conclusions and Relevance Although individual level risk remains moderate to low and results from this study should be confirmed in future adequately powered prospective studies, the high prevalence of adolescents consuming cannabis generates a large number of young people who could develop depression and suicidality attributable to cannabis.

Because all Cannabis types are eminently capable of cross breeding to produce fertile progeny, it is unlikely that any clear winner will emerge between the \"lumpers\" vs. \"splitters\" in this taxonomical debate. This is compounded by the profusion of Cannabis varieties available through the black market and even the developing legal market. While labeled \"strains\" in common parlance, this term is acceptable with respect to bacteria and viruses, but not among Plantae. Given that such factors as plant height and leaflet width do not distinguish one Cannabis plant from another and similar difficulties in defining terms in Cannabis, the only reasonable solution is to characterize them by their biochemical/pharmacological characteristics. Thus, it is best to refer to Cannabis types as chemical varieties, or \"chemovars.\" The current wave of excitement in Cannabis commerce has translated into a flurry of research on alternative sources, particularly yeasts, and complex systems for laboratory production have emerged, but these presuppose that single compounds are a desirable goal.

These include effects on executive, emotional, reward and memory processing via direct interactions with the endocannabinoid system and indirect effects on the glutamatergic, GABAergic and dopaminergic systems.

After critiquing previous conceptions of romanticism and discussing its first European manifestations, Lowy and Sayre propose a typology of the sociopolitical positions held by romantic writers from \"restitutionist\" to various revolutionary/utopian forms. In subsequent chapters, they give extended treatment to writers as diverse as Coleridge and Ruskin, Charles Peguy, Ernst Bloch and Christa Wolf. Among other topics, they discuss the complex relationship between Marxism and romanticism before closing with a reflection on more contemporary manifestations of romanticism (for example, surrealism, the events of May 1968, and the ecological movement) as well as its future.

At the same time, certain leading descriptions of the older canon, dominated by poetry and a handful of male writers, remained current, especially the notion that Romantic poetry sought transcendence and an ideal realm at the price of denying the body and material nature. This essay looks at a variety of new work on Romanticism and the body that challenges and revises that description, eliciting a pronounced materialist tendency found in a number of Romantic era discourses, authors, and texts. The new emphasis on the body and on the embodiment of mind brings together several subfields within Romantic scholarship, including literature and medicine, literature and scientific psychology, ecocriticism, environmental and diet studies, recent developments in colonial discourse studies and feminist criticism, and cognitive and neuroscientific approaches to reading Romanticism. Two of the most exciting developments in British Romantic scholarship during the 1990s not only contributed to new critical and theoretical perspectives on the field, but have changed the very way that the field is constituted: what \"counts\" as a Romantic text, what gets anthologized, what gets taught. The recovery and revaluation of Romantic era texts written by women, growing out of the feminist critique of canonical, male authored texts in the 1980s, effectively transformed and rejuvenated the field: dozens of authors barely mentioned for over a century came back into focus not to mention into print in ways that challenged reigning descriptions of Romanticism and threw \"Romanticism\" itself as a descriptive term into crisis. Even authors who had long remained available, most notably Jane Austen and Mary Shelley, became newly central to the field: for the first time, a young Romanticist might be expected to know and teach Emma as well as The Prelude Alongside of (and overlapping with) the new scholarship on women writers, came an unprecedented attention to the relation of Romantic era culture to matters of empire and colonialism, nation and ethnicity, slavery, and \"race.\" This newly globalized", "corpus_id": 55434103, "venue": "", "year": 2004, "author_names": [ "Alan Francis F Richardson" ], "n_citations": 8, "n_key_citations": 1, "score": 0 }, { "doc_id": "171014231", "title": "The Ethics of Romanticism", "abstract": "Acknowledgments Editions and abbreviations Introduction Part I.

He stresses that Romanticism was produced only by Western Christian civilization, with its unique view of humankind's relationship to God. The Romantic's frantic and heroic striving after unreachable goals mirrors Christian beliefs in human inability to adequately address God, speak to God, or praise God.

Objective The objective of this systematic review was to identify research on health professionals' perceived usability and practice behavior change of information and communication technologies for the dissemination of clinical practice guidelines. Methods We used a systematic approach to retrieve and extract data about relevant studies. We identified 2248 citations, of which 21 studies met criteria for inclusion; 20 studies were randomized controlled trials, and 1 was a controlled clinical trial. The following information and communication technologies were evaluated: websites (5 studies) computer software (3 studies) Web based workshops (2 studies) computerized decision support systems (2 studies) electronic educational game (1 study) email (2 studies) and multifaceted interventions that consisted of at least one information and communication technology component (6 studies) Results Website studies demonstrated significant improvements in perceived usefulness and perceived ease of use, but not for knowledge, reducing barriers, and intention to use clinical practice guidelines. Computer software studies demonstrated significant improvements in perceived usefulness, but not for knowledge and skills. Web based workshop and email studies demonstrated significant improvements in knowledge, perceived usefulness, and skills. An electronic educational game intervention demonstrated a significant improvement from baseline in knowledge after 12 and 24 weeks. Computerized decision support system studies demonstrated variable findings for improvement in skills. Multifaceted interventions demonstrated significant improvements in beliefs about capabilities, perceived usefulness, and intention to use clinical practice guidelines, but variable findings for improvements in skills. Most multifaceted studies demonstrated significant improvements in knowledge. Conclusions The findings suggest that health professionals' perceived usability and practice behavior change vary by type of information and communication technology.

They are at risk for adverse outcomes such as delirium, infection, and iatrogenic complications, and these complications, in turn, contribute to the risk of functional decline, nursing home admission, and death. Whether preoperative and perioperative comanagement by a geriatrician reduces the incidence of in hospital complications and length of in hospital stay after elective lumbar spine surgery remains unknown. METHODS A unique model of comanagement for elderly patients undergoing lumbar fusion surgery was implemented at a major academic medical center. The Perioperative Optimization of Senior Health (POSH) program was launched with the aim of improving outcomes in elderly patients 65 years old) undergoing complex lumbar spine surgery. In this model, a geriatrician evaluates elderly patients preoperatively, in addition to performing routine preoperative anesthesia surgical screening, and comanages them daily throughout the course of their hospital stay to manage medical comorbid conditions and coordinate multidisciplinary rehabilitation along with the neurosurgical team. The first 100 cases were retrospectively reviewed after initiation of the POSH protocol and compared with the immediately preceding 25 cases to assess the incidence of perioperative complications and clinical outcomes. RESULTS One hundred twenty five patients undergoing lumbar decompression and fusion were enrolled in this pilot program. Baseline characteristics were similar between both cohorts. The mean length of in hospital stay was 30% shorter in the POSH cohort (6.13 vs 8.72 days; p 0.06) The mean duration of time between surgery and patient mobilization was significantly shorter in the POSH cohort compared with the non POSH cohort (1.57 days vs 2.77 days; p 0.02) and the number of steps ambulated on day of discharge was 2 fold higher in the POSH cohort (p 0.04) Compared with the non POSH cohort, the majority of patients in the POSH cohort were discharged to home (24% vs 54% p 0.01) CONCLUSIONS Geriatric comanagement reduces the incidence of postoperative complications, shortens the duration of in hospital stay, and contributes to improved perioperative functional status in elderly patients undergoing elective spinal surgery for the correction of adult degenerative scoliosis.", "corpus_id": 25215315, "venue": "Journal of neurosurgery.

The Student t test was used for continuous variables, and Pearson's chi square test was used for categorical variables. RESULTS Of the 2698 of patients identified with traumatic cervical spine injuries, 103 patients demonstrated evidence of TVAI. Of these patients, 69 were 65 and 34 were 65 years old at the time of their trauma. There was no difference in the incidence of TVAIs between the 2 groups. The ICU length of stay (4.71 vs 4.32 days, p 0.05) hospital length of stay (10.71 vs 10.72 days, p 0.05) and the ISS (21.50 vs 21.32, p 0.05) did not differ significantly between the 2 groups. Mortality was significantly higher in the geriatric group, occurring in 9 of 34 patients (26.5% compared with only 3 of 69 patients (4.4% in the adult group (p 0.001) Ground level falls were the most common inciting event in the geriatric group (44% vs 14.5% p 0.001) whereas motor vehicle accidents were the most common etiology in the younger population (72.5% vs 38.2% p 0.001) Incidence of ischemic stroke did not vary significantly between the 2 groups (p 0.05) CONCLUSIONS TVAI in the older adult population is associated with a significantly greater risk of mortality than in the younger adult population, despite the 2 groups having similar ISSs. Additionally, low velocity mechanisms of injury, such as ground level falls, are a greater risk factor for acquired TVAI in older adults than in younger adults, in whom it is a significantly less common etiology.", "corpus_id": 210709463, "venue": "Journal of neurosurgery.

Delirium is a syndrome that causes serious consequences, increasing mortality and morbidity rates and extending the length of hospital stay. The aim of this study was to evaluate the validity and reliability of the Turkish version of the Nursing Delirium Screening Scale (Nu DESC) Method: One hundred twelve patients who were hospitalized for a surgical operation in the orthopedics, neurosurgery, and general surgery clinic of a state hospital for 3 months were evaluated concurrently (and independently for delirium) Patients were observed by clinical nurses 3 times over a 24 h period. The presence of delirium was diagnosed by 2 neurologists according to DSM IV criteria. Student's t test, the kh2 test, and the Mann Whitney U test were used, and construct validity, intrascale factor analysis, interrater reliability, and specificity and sensitivity (ROC) analyses were performed for descriptive analysis. SPSS 25.0 and MedCalc18.6 were used for statistical analysis. Results: Delirium was detected in 28 patients according to the Nu DESC. The ICC (intraclass correlation) is 0.97 in the 95% confidence interval from 0.96 to 0.98 for agreement between nurses and neurologists for the total Nu DESC score. Weighted k rates were between 0.78 and 0.92.

An analysis was made on variables such as: age, pathology, length of stay, comorbidity, performance status, re admissions and mortality. RESULTS Similar numbers of patients were admitted during the two periods: 409 and 413. However, there was an increase of 77.5% in patients older than 70 years: 80 versus 142.

We measure the depth/diameter ratio of approximately 2,000 simple craters near the north pole of Mercury using Mercury Laser Altimeter data. We find that these craters become distinctly shallower at higher latitudes, where ice is known to have accumulated on their floors. This shallowing corresponds to a maximum infill of around 50 m, consistent with previous estimates. A parallel investigation of approximately 12,000 lunar craters using Lunar Reconnaissance Orbiter data reveals a similar morphological trend near the south pole of the Moon, which we conclude is also due to the presence of thick ice deposits.

To date, however, there have only been very few laboratory oblique impact experiments for analogue targets relevant to the surfaces of extraterrestrial bodies. In particular, there is a lack of laboratory oblique impact experiments into brittle targets with a material strength on the order of 1 MPa, with the exception of ice. A strength on the order of 1 MPa is considered to be the corresponding material strength for the formation of craters in the 100 m size range on the Moon. Impact craters are elliptical if the meteoroid's trajectory is below a certain threshold angle of incidence, and it is known that the threshold angle depends largely on the material strength. Therefore, we examined the threshold angle required to produce elliptical craters in laboratory impact experiments into brittle targets. This work aims to constrain current interpretations of lunar elliptical craters and pit craters with sizes below a hundred meters. We produced mortar targets with compressive strength of 3.2 MPa. A spherical nylon projectile (diameter 7.14 mm) was shot into the target surface at a nominal velocity of 2.3 km/s, with an impact angle of 5deg 90deg from horizontal. The threshold angle of this experiment ranges from 15deg to 20deg. We confirmed that our experimental data agree with previous empirical equations in terms of the cratering efficiency and the threshold impact angle. In addition, in order to simulate the relatively large lunar pit craters related to underground cavities, we conducted a second series of experiments under similar impact conditions using targets with an underground rectangular cavity. Size and outline of craters that created a hole are similar to those of craters without a hole. Moreover, when observed from an oblique angle, a crater with a hole has a topography that resembles the lunar pit craters. The relation between the impact velocity of meteoroids on the Moon and the probability of elliptical crater formation was investigated based on our experimental results and an existing empirical equation.

The most numerous and significant landforms belong to a size morphology series of simple craters, complex craters, and ringed basins that were formed by impacts. Each crater and basin is the source of primary ejecta and secondary craters that, collectively, cover the entire terra. The largest impacts thinned, weakened, and redistributed feldspathic terracrustal material averaging about 75 km in thickness. Relatively small volumes of basalt, generated by partial remelting of mantle material, were erupted through the thin subbasin and subcrater crust to form the maria that cover 16 percent of the lunar surface. Tectonism has modified the various stratigraphic deposits relatively little; most structures are confined to basins and large craters. This general geologic style, basically simple though complex in detail, has persisted longer than 4 aeons (1 aeon 109 yr) Impacts began to leave a visible record about 4.2 aeons ago, after the crust and mantle had differentiated and the crust had solidified.

Although theoretical spallation models were developed about three decades ago, only limited geological observations have been made so far to test these models. The 3.8 km Censorinus crater on the Moon provides an excellent opportunity for studying the impact spallation processes associated with a fresh simple crater formed by oblique impact. Using the Lunar Reconnaissance Orbiter Narrow Angle Camera images, we prepared the ejecta boulder distribution map of Censorinus crater and measured the boulder sizes and shapes. Mapping of about 242,000 ejecta boulders enabled us to document the size distribution of boulders both radial and concentric to the impact crater. Larger size boulders dominate the crater rim areas, while they become smaller away from the crater. The boulder distribution exhibits a radial asymmetry suggesting Censorinus is a oblique impact, in which the uprange ejecta have smaller ranges with larger concentration of boulders near the southwestern crater rim, while the downrange ejecta are in general characterized by smaller boulders with high spatial dispersion. The cumulative size frequency distribution (CSFD) of boulders shows a highly variable fragmentation history in which the uprange boulders suffered more complex fragmentation. The ejecta boulders also exhibit a variety of shapes that are gleaned from their axial ratios and edge angle characteristics. There is a general decrease of axial ratios away from the crater rim. Rectangular boulders dominate the crater rim and they become more equant away from the crater. In addition to the boulder sizes, the boulder shape distribution also exhibits a mild asymmetry in response to the oblique impact. Small size fresh impact craters (84,000 craters) are abundant on the Censorinus ejecta and post date Censorinus. These craters are found in two morphologic types in which a large majority of craters have subdued ejecta (rayless craters) while some possess bright rayed ejecta (bright rayed craters) The CSFD of rayless craters show a steep power law slope with a b value of 4.0, similar to the secondary craters produced by the impact of ejecta from primary craters. We therefore interpret the rayless craters as the secondary craters of Censorinus. On the other hand, the CSFD of bright rayed craters have smaller power law slope b value 2.7) which is a characteristic of primary craters, and thus provide 3 Ma age for Censorinus crater. When the characteristics of Censorinus boulders are compared with the theoretical spallation models that are sensitive to the petrophysical properties of the target (lunar highland) the models generally agree with the Censorinus boulders.

Given the similarities between the two bodies it is probable that similar processes control this spatial association on both. However, the precise morphology and localization of the activity differs on the two bodies, indicating that the nature of structures beneath impact craters and/or volcanic activity may also be different. To explore this, we analyze sites of explosive volcanism within complex impact craters on the Moon and Mercury, comparing the scale and localization of volcanic activity and evidence for post formation modification of the host crater. We show that the scale of vents and deposits is consistently greater on Mercury than on the Moon, indicating greater eruption energy, powered by a higher concentration of volatiles. Additionally, while the floors of lunar craters hosting explosive volcanism are commonly fractured, those on Mercury are not. The most probable explanation for these differences is that the state of regional compression acting on Mercury's crust through most of the planet's history results in deeper magma storage beneath craters on Mercury than on the Moon. The probable role of the regional stress regime in dictating the depth of intrusion on Mercury suggests that it may also play a role in the depth of sub crater intrusion on the Moon and on other planetary bodies. Examples on the Moon (and also on Mars) commonly occur at locations where flexural extension may facilitate shallower intrusion than would be driven by the buoyancy of the magma alone.", "corpus_id": 14608607, "venue": "", "year": 2015, "author_names": [ "Rebecca J Thomas", "David A Rothery", "Susan J Conway", "Mahesh Anand" ], "n_citations": 21, "n_key_citations": 3, "score": 0 }, { "doc_id": "16012295", "title": "Comparisons of fresh complex impact craters on Mercury and the Moon: Implications for controlling factors in impact excavation processes", "abstract": "The impact cratering process is usually divided into the coupling, excavation, and modification stages, where each stage is controlled by a combination of different factors. Although recognized as the main factors governing impact processes on airless bodies, the relative importance of gravity, target and projectile properties, and impact velocity in each stage is not well understood. We focus on the excavation stage to place better constraints on its controlling factors by comparing the morphology and scale of crater exterior structures for similar sized fresh complex craters on the Moon and Mercury. We find that the ratios of continuous ejecta deposits, continuous secondaries facies, and the largest secondary craters on the continuous secondaries facies between same sized mercurian and lunar craters are consistent with predictions from gravity regime crater scaling laws. Our observations support that gravity is a major controlling factor on the excavation stage of the formation of complex impact craters on the Moon and Mercury. On the other hand, similar sized craters with identical background terrains on Mercury have different spatial densities of secondaries on the continuous secondaries facies, suggesting that impactor velocity may also be important during the excavation stage as larger impactor velocity may also cause greater ejection velocities. Moreover, some craters on Mercury have more circular and less clustered secondaries on the continuous secondaries facies than other craters on Mercury or the Moon. This morphological difference appears not to have been caused by the larger surface gravity or the larger median impact velocity on Mercury. A possible interpretation is that at some places on Mercury, the target material might have unique properties causing larger ejection angles during the impact excavation stage.

Accurate diagnosis of asthma is the first step to managing occupational asthma, which can be sensitizer induced or irritant induced asthma. While latency has traditionally been recognized as a hallmark of sensitizer induced asthma and rapid onset a defining feature of irritant induced asthma (as in Reactive Airway Dysfunction Syndrome) there is epidemiological evidence for irritant induced asthma with latency from chronic moderate exposure. Diagnostic testing while the patient is still in the workplace significantly improves sensitivity. While specific inhalational challenges remain the gold standard for the diagnosis of occupational asthma, they are not available outside of specialized centers. Commonly available tests including bronchoprovocation challenges and peak flow monitoring are important tools for practicing clinicians. Management of sensitizer induced occupational asthma is notable for the central importance of removal from the causative agent: ideally, removal of the culprit agent; but if not feasible, this may require changes in the work process or ultimately, removal of the worker from the workplace. While workers' compensation programs may reduce income loss, these are not universal and there can be significant socio economic impact from work related asthma.

The present study investigated differences between two ethnic groups studying in New Zealand (Asian and European) with respect to their disclosures of academic dishonesty and engagement with ethical learning experiences (ELE) Responses from 312 pharmacy and medical students were analysed in this study. A questionnaire was designed to elicit responses about engagement in academic dishonesty and ELEs.

The findings showed small but significant differences between Asian and European students with respect to disclosure in the areas of copying and collusion. Subtle interactions were also noted for ethnicity and year of study, and ethnicity and gender, indicating that later year students diverged more than earlier year students and differences were more apparent amongst male students.

METHODS All tertiary institutions providing training for medicine, nursing, midwifery, dentistry, pharmacy, physiotherapy, dietetics and 11 other allied health professions in New Zealand were contacted and a person with relevant curriculum knowledge was invited to participate. Interviews were conducted using a semi structured interview guide to explore nine quality and safety domains; improvement science, patient safety, quality and safety culture, evidence based practice, patient centred care, teamwork and communication, leadership for change, systems thinking and use of information technology (IT) Transcribed data were extracted and categorised by discipline and domain. Two researchers independently identified and categorised themes within each domain, using a general inductive approach. RESULTS Forty nine institutions were contacted and 43 (88% people were interviewed. The inclusion and extent of quality and safety teaching was variable. Evidence based practice, patient centred care and teamwork and communication were the strongest domains and well embedded in programmes, while leadership, systems thinking and the role of IT were less explicitly included. Except for two institutions, improvement science was absent from pre registration curricula. Patient safety teaching was focused mainly around incident reporting, and to a lesser extent learning from adverse events. Although a 'no blame' culture was articulated as important, the theme of individual accountability was still apparent. While participants agreed that all domains were important, the main barriers to incorporating improvement science and patient safety concepts into existing programmes included an 'already stretched curriculum' and having faculty with limited expertise in these areas.

As primary care providers pharmacists are at the forefront, providing information and guidance to patients about safe and effective use of all medicines, including complementary medicines. Surveys of Australian community pharmacists show that their CAM training does not meet their professional needs and that their lack of suitable training prevents information provision on CAM. Similarly, student surveys mostly show that graduates don't feel comfortable with CAM counselling. Although most pharmacy Schools in Australia and New Zealand offer some form of CAM training, the extent to which CAM is taught and integrated varies widely due to the fact that its integration is not a unifying requirement and is handled quite differently at amongst institutions. This study evaluates the scope of CAM teaching in pharmacy programs in Australia and New Zealand's Schools of Pharmacy. Methods: All 18 Schools/Departments offering Pharmacy programs in New Zealand and Australia were invited to participate in a 30 item cross sectional survey in 2010. Ethical clearance for the study was obtained through Griffith University's Human Research Ethics Committee. Survey Data analysis was performed using SPSS version 18.0. Descriptive statistics such as frequencies, means standard deviations and ranges were used to summarise the data. For the Likert responses, all responses with any degree of agreement were grouped together as positive responses, and all responses with any degree of disagreement were grouped together as negative response. T tests and chi square were used to analyse differences as appropriate. Results were considered significant when the p value was less than 0.05. Results: Ten Schools responded, 9 from Australia and 1 from a New Zealand. All except 1 reported integrating CAM teaching into the curriculum. Three Schools stated that they will be changing content, but no school was going to decrease the CAM content. During the whole pharmacy degree on average only 22h (including lectures, workshops, tutorials etc. were taught on CAM with a larger proportion of Schools (67% offering less than 22h of CAM content. Similarly, in the majority of Schools CAM content was included in less than 50% of assessment items. Only 5 Schools included CAM tasks into placement exercises. A thorough content analysis showed that the CAM content varied significantly between Schools in some areas, and that content currently taught was quite different from what the participating academics thought was essential. As CAM information sources the majority of Schools recommended professional pharmacy reference books and general websites rather than specific evidence based CAM websites. Academics responsible for CAM teaching had very different levels of employment and expertise with only one School reporting on a dedicated chair in the CAM discipline. Participating academics did not agree on the necessity of preceptor and school staff CAM training. Conclusion: The findings in this study suggest that more consideration should be given to appropriate and comprehensive CAM content in pharmacy curricula across Australia and New Zealand to meet the professional and care needs of pharmacists and their patients, respectively.

Functional inference of identified taxa was performed using PICRUSt.ResultsWe report a significant difference in alpha diversity in GI microbiota among men with versus without a prostate cancer diagnosis.

Current research focuses on various sources of text based information, including social media where enormous amounts of user posted data is available, which have the potential for use in pharmacovigilance if collected and filtered accurately. The aims of this study are: (i) to explore natural language processing (NLP) approaches for generating useful features from text, and utilizing them in optimized machine learning algorithms for automatic classification of ADR assertive text segments; (ii) to present two data sets that we prepared for the task of ADR detection from user posted internet data; and (iii) to investigate if combining training data from distinct corpora can improve automatic classification accuracies. METHODS One of our three data sets contains annotated sentences from clinical reports, and the two other data sets, built in house, consist of annotated posts from social media. Our text classification approach relies on generating a large set of features, representing semantic properties (e.g. sentiment, polarity, and topic) from short text nuggets. Importantly, using our expanded feature sets, we combine training data from different corpora in attempts to boost classification accuracies. RESULTS Our feature rich classification approach performs significantly better than previously published approaches with ADR class F scores of 0.812 (previously reported best: 0.770) 0.538 and 0.678 for the three data sets. Combining training data from multiple compatible corpora further improves the ADR F scores for the in house data sets to 0.597 (improvement of 5.9 units) and 0.704 (improvement of 2.6 units) respectively.

Are they the result of lower intakes of harmful dietary components, in particular meat? and Are they the result of higher intakes of beneficial dietary components that tend to replace meat in the diet? Current evidence suggests that the answer to all 3 questions is \"Yes.\" Low smoking rates contribute importantly to the low rates of cardiovascular disease and many cancers, probably including colon cancer, in Seventh day Adventists and other vegetarian populations. Also, avoidance of red meat is likely to account in part for low rates of cardiovascular disease and colon cancer, but this does not appear to be the primary reason for general good health in these populations.

The review considered the philosophy of science and focussed on the concept of value as a point of synthesis among the disciplines of LCA, economics and ethics. An example from the ELCC Code of Practice was reviewed to highlight the challenges and alternative approaches explored.Results and discussion'Value choices' and the role of decision makers have been a long standing and largely unresolved discussion in LCA. Over the past two decades, LCA has been dominated by a utilitarian concept of ethics and valuation based on willingness to pay. This has a number of limitations which are further exacerbated in ELCC and its accounting definition of cost. ELCC struggles to address social costs, and the focus on the decision maker may define values that are not compatible with sustainability. John Rawls' 'justice as fairness' and Amartya Sen's capability approach were considered to reappraise the use of UN Conventions considered in early LCA literature on values. It was argued that there is an ethical basis to prioritise minimum standards in LCSA to address primary social goods as well as uncertainty in evaluations.ConclusionsThis paper questioned the reliance of LCA on utilitarianism and valuation using willingness to pay and, in particular, the claim of ELCC as the economic pillar of LCSA. Concepts of fairness and capability may overcome some of these limitations and provide a basis for integration of social, economic and environmental pillars of sustainability. Although the ethical justification of prescriptive values may only reach agreement on minimum conditions for social and economic cooperation, it was argued that this may provide a reasonable starting point given the global sustainability challenges over the coming decades.

Much ink has been spilled over this debate and for good reasons. The global prevalence of obesity has more than doubled since the 1980s and is now of pandemic proportions. Whether obesity is a disease has consequences for what kind of treatments are appropriate, as well as how we ought to allocate funding and access to healthcare resources. In most cases, there is no dispute over the medical facts, yet disagreement persists. This is because whether obesity is a disease is not determined by medical facts alone; the issue is, in part, conceptual. Science relies on careful argumentation and conceptual analysis as part of its armamentarium. In this review, we will examine the two concepts of disease most often employed in the philosophy of medicine: the naturalistic and constructivist.

Such review is necessary but certainly not suffi cient given the complexity of the tasks ahead. We will need more than the quantitative language of outcome measures to talk about values and not numbers, patient care and not effi ciency, and the balance between access and quality. Although policymakers have enveloped themselves in jargon that purports to answer such questions, the language of the clinic and health policy is often ill equipped to deal with these themes. Philosophy, history, literature, and the arts already offer a discourse instrumental to refl ective practice. These disciplines encourage introspection and a deeper understanding of how medicine operates within society. Such refl ection has a \"transformative power,\" enabling practitioners to, in John Dewey's words, \"reconstruct\" the world. 1 In order to learn from the humanities, as profound organizational changes in the healthcare system begin, we must take several steps to sustain these disciplines in the healthcare setting. First, we must remind our medical and academic colleagues of the importance of the humanities writ large. Regaining a proper place for the humanities in medical school poses a signifi cant challenge, as some think it is achieved by displacing the sciences or by being oppositional to them. This is an unfortunate misinterpretation, and it must be stressed that the additional perspective offered by the humanities is not a zero sum gain. It enriches, and grows from, scientifi c discovery. A deeper perspective on our shared work is achieved not by denigrating the sciences but by responding to them and by adopting a more inclusive approach that engenders support from our friends and colleagues in the sciences.

A second aim is to shift the current debate on methodologies to an epistemological level, presenting the first results of an ongoing critical review about which underlying paradigms have been applied in sLCA literature.MethodsThis paper moves from the hypothesis that the diversity of positions in philosophy of science and the \"multiparadigmatic\" character of social sciences have had repercussions on sLCA literature since its beginnings, probably in an unconscious manner. Therefore, a discriminating reflection on the scientific and disciplinary inheritance that can represent the roots of sLCA has been conducted. The philosophy of science and the role of different research paradigms in social sciences have been deepened to provide an overview of the main elements of a paradigm (in terms of ontology, epistemology, and methodology) Finally, a brief but critical review of 133 selected scientific contributions on sLCA has been conducted to highlight which paradigms have been applied in sLCA studies.Results and discussionRecognizing that boundaries between paradigms are subtle and that researchers are rarely conscious of which paradigm underpins their works, a distinction between the interpretivist and post positivist approaches used by the studies has been carried out on the basis of a text analysis conducted by identifying the main \"literal\" criteria. From an initial population of 209 studies, we excluded those concerning reviews of sLCA literature and those with selected criteria that were insufficient to catch the epistemological viewpoint of the authors. Among the remaining papers (133) 73 has been ascribed to the group of interpretivism oriented paradigms and only 24 could be ascribed to the post positivist one; the remaining 3 is represented by studies with both characteristics. This data deserves some attention because, since the beginnings of sLCA methodologies, most sLCA publications explicitly suggest having the same underlying perspectives as environmental life cycle assessment (eLCA).ConclusionsIn light of the reflections carried out, we argue that it is important, before going into methodological questioning issues, to be aware of which paradigm is underlying. Indeed, in this phase of sLCA development, scholars should go beyond the simple methodological debate and recognize the \"multilayered\" nature of social phenomena and the multiparadigmatic characteristics of social and management sciences.", "corpus_id": 113827413, "venue": "The International Journal of Life Cycle Assessment", "year": 2016, "author_names": [ "Nathalie Iofrida", "Anna Irene De Luca", "Alfio Strano", "Giovanni Gulisano" ], "n_citations": 36, "n_key_citations": 3, "score": 0 }, { "doc_id": "12088823", "title": "A confusion of tongues between psychoanalysis and philosophy: Is the controversy over drive versus relational theory a philosophical one?", "abstract": "In recent years the controversy over Drive versus Relational models of the psyche has become entangled in a philosophical controversy over epistemology.

The mentioned progress, together with interesting applications, increased the number of research monographs dedicated to the subject of soliton equations. The variety of approaches used in these monographs reflects the variety of the methods used in the study of the soliton equations. In general however, most of them are dedicated to the development of one particular approach and the interrelations with other approaches and ideas frequently remains obscure. The book under review is one of the few exceptions. It develops in parallel spectral and geometric methods to the topic and also encompasses many algebraic ideas related to these fields. The fist edition has been published in 2008, by the same publisher. The appearance of this soft cover reprint shows that the readers appreciated the integral approach of the book and that the topic itself remains popular. The book has two parts: I) Spectral Theory of the Recursion Operators and II) Geometry of the Recursion Operators, treating the so called Recursion Operators (also known as generating operators or L operators) from spectral and geometric viewpoint respectively.

The discipline concerned with the application of computational methods and devices to these ends is called computational mechanics, and it has emerged as a key area of research, education, and application throughout the world. The international group of scholars and practitioners of this new discipline founded the international Association of Computational Mechanics (IACM) to promote advances in computational mechanics. To establish the breadth of this activity IACM defines in its constitution the field of Computational Mechanics as follows: \"For the purposes of the Association we define the subject of Computational Mechanics as the development and application of numerical methods and digital computers to the solution of problems posed by Engineering and Applied Science with the objectives of understanding and harnessing the resources of nature. While Computational Solid Mechanics (CSM) and Computational Fluid Dynamics (CFD) are at the core of our activity, such subjects as Thermodynamics, Electro Magnetism, Rigid Body Mechanics, Control Systems and some aspects of Particle Physics fall naturally within the scope of the definition. Indeed the provision of a common forum for discussion, education and research information transfer between the diverse disciplines represented is the main \"raison d'etre\" of the Association.\" The first attempt to bring together this community followed a letter from three leading scientists working in this field, R.H. Gallagher, J.T. Oden and O.C. Zienkiewicz who called a meeting of 12 persons at Georgia Institute of Technology, Atlanta, Georgia, U.S.A. in April 1981 to form a group of International Centers of Computational Mechanics. This led to the formal announcement of IACM and the establishment of a Founding Council and a Constitution. IACM was formally established, the General and Executive Councils confirmed and the Constitution approved. With the Constitution giving equal emphasis to the three geographical Regions of Americas, Euro Africa and Australia Asia a rotation of such World Congresses between the regions on a four year cycle was established. The International Association of Computational Mechanics (IACM) was founded to promote advances in computational mechanics by the international group of scholars and practitioners of this new discipline.

In the past two decades, extensive experimental, theoretical and numerical research had been conducted to reveal their importance in RF discharge. However, obvious contradictions, which cannot be easily accommodated for different discharge conditions, are found between experiments and theories/simulations and between simulations using different models as well. This clearly indicates an insufficient understanding of physical processes involving metastables in RF discharge. To shed new light on the role of metastables on RF discharge, the present work employs combined PIC/MCC and Direct Simulation Monte Carlo (DSMC) methods to study the dynamics of metastables in RF discharge. Both plasmas (ions and electrons) and metastables are treated as particles in the simulation and are coupled though various collision processes, such as metastable excitation, pooling, electron quenching, step ionization, metastable wall secondary electron emission, neutral metastable elastic collisions, in addition to those included in typical PIC/MCC simulation, such as direct ionization and excitation.

They can advertise products or services with free items or discounts to spread positive opinions to other consumers (i.e. word of mouth) However, main research on choosing the best influentials to target is single objective and mainly focused on maximizing sales revenue. In this paper we propose a multiobjective approach to the influence maximization problem with the aim of increasing the revenue of viral marketing campaigns while reducing the costs. By using local social network metrics to locate influentials, we apply two evolutionary multiobjective optimization algorithms, NSGA II and MOEA/D, a multiobjective adaptation of a single objective genetic algorithm, and a greedy algorithm. Our proposal uses a realistic agent based market framework to evaluate the fitness of the chromosomes by simulating the viral campaigns. The framework also generates, in a single run, a set of non dominated solutions that allows marketers to consider multiple targeting options The algorithms are evaluated on five network topologies and a real data generated social network, showing that both MOEA/D and NSGA II outperform the single objective and the greedy approaches.

However, almost all prior work focused on cardinality constraint or considers only simple comparative products model. They neglected that composite complementary products (CCP) are widespread. In other words, when a customer adopts products <inline formula> <tex math notation=\"LaTeX\"$A$ /tex math>/inline formula> and <inline formula> <tex math notation=\"LaTeX\"$B$ /tex math>/inline formula> at the same time, it is possible for him to adopt product <inline formula> <tex math notation=\"LaTeX\"$C$ /tex math>/inline formula> Therefore, we design a multi layer network model under independent cascade (IC) model to adapt to multiple complementary products and define the seed selection problem for complementary products model [IM for complementary products (IMCP) and CCP model (IMCCP) under knapsack constraint.

Despite its apparent effectiveness, prediction of whether such advertising will be highly shared is a poorly understood area of marketing. Advances in brain imaging techniques may allow researchers to forecast aggregate consumer behavior beyond subjective reports. Using neuroimaging techniques, previous research has established models showing that expectations of self related outcomes (potential for self enhancement) and the social impact of sharing (potential for social approval) contribute to the likelihood of users sharing non commercial static content (i.e. text based health news) However, whether this finding can be applied to forecasting the virality of dynamic commercial stimuli, which is more relevant to interactive marketing (i.e. video ads) remains unknown. Combining brain imaging techniques, cross validation methods, and real world data regarding sharing on social media, the present study investigated whether brain data can be used to forecast the viral marketing success of video ads. We used neuroimaging (functional magnetic resonance imaging: fMRI) to measure neural activity during three sets of theory driven neural measures implicated in value, self, and social (mentalizing) processes while 40 participants viewed video ads that brands had posted on Facebook. Contrary to previous findings regarding value related virality in non commercial static content, our results indicate that social related neural activity contributes significantly to forecasting the virality of dynamic marketing related content. The model that included both social related neural measures and subjective intentions to share forecasted viral marketing success better than the model that included only social related neural measures. The model that included only subjective intention to share did not forecast viral marketing success.

The identification of the elements of the model has been performed through a sectoral review of air cargo, an analysis of the entire logistics chain including the physical flow, the documentary flow, and all the agents involved in it. The analysis of the logistics chain has been carried out from the operational, technological, socio economic and environmental standpoint, considering all the factors that influence the competitiveness of the logistics chain. Specifically, the operational characteristics that an air cargo transport requires both at the airport infrastructure and the logistics operators level, the technologies for the handling of freight and its control (on land and on board) have been examined. Other characteristics include the different types of products transported according to their characteristics, the associated supply chains considering locations and routes with their origins and destinations, and the existing markets with the main demands of each type of merchandise. The model has been developed by using the Analytic Hierarchy Process methodology with absolute measurements. This methodology considers the judgements of experts in terms of the weightings of the different factors and attributes that constitute the model. The Zaragoza airport has been used for the model assessment. Furthermore, minimum thresholds were established for the attributes.

Inheritance and the kinship system are of fundamental importance in Jewish law. Thus it is crucial to protect the integrity of the kinship system, to preserve clarity about parentage and all matters of ancestry, and to preserve liceity, that is, fidelity to law, in kinship. Surrogacy, gamete donation, and other assisted reproduction techniques present new genealogical issues that demand consideration in the context of Jewish tradition. Incest is seen as repugnant today, as it was in ancient times. Incest can have devastating medical consequences for children whose parents are close relatives.

I was left wanting a more formal conclusion in its wake, especially since here her reasons for rejecting the alleged interpolation identify wider assumptions and problems affecting the field of ancient Jewish literature (e.g. the Damascus Document) more broadly. By relegating these points mostly to footnotes and providing no concluding reflections on their broader implications, Halpern Amaru undersells the significance of her work. Halpern Amaru's meticulous footnotes thoroughly engage the manuscript evidence, acknowledging when she must (propose and) rely on a reconstruction of the Hebrew based on a particular medieval Ethiopic reading. She transliterates and translates the Ge'ez, but often leaves Hebrew untranslated, a logical and handy approach for most scholars of ancient Judaism. Halpern Amaru juggles so much linguistic, literary, and exegetical data that her arguments would be obscured (and her book too lengthy) if she consistently rendered things intelligible for those who cannot read Hebrew. But this obviously limits accessibility for scholars more skilled in New Testament literature that, like Jubilees, is similarly saturated with representative allusions and implicit exegesis. Halpern Amaru's willingness to engage and consider Jubilees as \"a unitary text that may reflect the work of a single author or the hand of a final editor\" (21) allows her to see and account for nuanced details of biblical exegesis, theology, and literary expression that the source critical approaches of other scholars have missed. This holistic \"literary approach\" to the text (20) provides a model not only for future work in Jubilees, but, in the eyes of this reviewer, for study of 1 2 Chronicles, the Damascus Document, and other works of Second Temple literature. In both substance of argument and method of approach, Halpern Amaru consistently and convincingly conveys what the author of Jubilees is doing (that is, what goes into and is conveyed by the composition) and how we, as scholars, should talk about it at the micro level of a particular passage of narrative or legislation, at the macro level of the more prolonged literary efforts sustained across the book as a unity, and at so many intervening loci where such micro and macro efforts converge.", "corpus_id": 165632476, "venue": "AJS Review", "year": 2018, "author_names": [ "Shaye J D Cohen" ], "n_citations": 0, "n_key_citations": 0, "score": 0 }, { "doc_id": "144233122", "title": "Inheriting the Crown in Jewish Law: The Struggle for Rabbinic Compensation, Tenure and Inheritance Rights By Jeffrey I.

In his legal history of the rabbinic profession from biblical to modern times, Jeffrey I. Roth traces the development of principles governing compensation and related benefits for rabbis, scholars, teachers, and judges under Jewish law. Roth focuses on the disconnect that evolved as rabbis wished to serve God and their communities yet needed to provide for the material needs of their families. He charts the shift from the Talmudic ideal of uncompensated service and follows the development of four material advantages sought by the rabbinic profession compensation, protection against competition, principles of tenure in office, and inheritance rights. Roth assesses how Jewish legal authorities dealt with seemingly conflicting material and spiritual requirements. Analyzing two millennia of legal and intellectual history, he depicts the struggle of rabbinical authorities and scholars of the Torah to answer questions about their profession in a way that allowed the rabbinate to survive while limiting compromises with received standards. Through vivid historical vignettes, Roth tells a story of legal ingenuity and religious courage, of flexibility in Jewish law, and of a responsiveness to changing circumstances that ultimately, although often hesitantly, laid the foundation for the modern rabbinate. In one of the few studies of the rabbinate cutting across countries and movements, Roth places rabbis in the social and economic contexts of their times and depicts them not just as religious leaders but as wage earners, providers for their dependents, and competitors in the provision of fee based services for the more lucrative and prestigious positions.

However, GANs have a fixed output size, so creating levels of arbitrary size for a dungeon crawling game is difficult. GANs also have trouble encoding semantic requirements that make levels interesting and playable. This paper combines a GAN approach to generating individual rooms with a graph grammar approach to combining rooms into a dungeon. The GAN captures design principles of individual rooms, but the graph grammar organizes rooms into a global layout with a sequence of obstacles determined by a designer. Room data from The Legend of Zelda is used to train the GAN.

On the one hand, \"The Legendary Hero\" peritext of The Wind Waker mirrors the game's reception history as one of departure from a Zelda tradition established by Ocarina of Time, which caused controversy initially yet gained acceptance in the long term. The audiovisual components of \"The Legendary Hero\" all position gamers to consider the events of Ocarina of Time as old, submerged under the Great Sea. Textual references to \"legend\" and \"myth,\" visual cues of antique art and runes, and musical cues harkening to medieval, Renaissance, and Baroque tropes within Western music all these serve to depart from Zelda tropes. On the other hand, the title screen peritext of Twilight Princess restores the legacy of Ocarina of Time. Reception of the former always includes its nostalgic, intimately connected relationship to the latter. Consequently, Twilight Princess garnered immediate praise but became problematic in the long term. The audiovisual components of the title screen peritext position gamers to reestablish continuity with Zelda tropes. Visual and musical cues reach across several previous games and as far back as the original The Legend of Zelda game, all of which orient players back to traditions from which the franchise had departed for years. Thus the music of the peritext enables players to engage in Zelda's potential for self reference more apparently than its adoption of Western music tropes, as in Wind Waker.

Bubble Entropy is based on permutation entropy, where the vectors in the embedding space are ranked. We use the bubble sort algorithm for the ordering procedure and count instead the number of swaps performed for each vector. Doing so, we create a more coarse grained distribution and then compute the entropy of this distribution. Results: Experimental results with both real and synthetic HRV signals showed that bubble entropy presents remarkable stability and exhibits increased descriptive and discriminating power compared to all other definitions, including the most popular ones. Conclusion: The definition proposed is almost free of parameters. The most common ones are the scale factor r and the embedding dimension m In our definition, the scale factor is totally eliminated and the importance of m is significantly reduced.

In this work, we report the crystallization processes of oiling out droplets on surfaces during solvent exchange. Our model ternary solution is beta alanine dissolved in isopropanol and water mixture. As the antisolvent isopropanol displaced the alanine solution pre filled in a microchamber, liquid liquid phase separation occurred at the mixing front. The alanine rich subphase formed surface microdroplets that subsequently crystallized with progression of solvent exchange. We find that the flow rates have significant influence on the droplet size, crystallization process, and growth rate, and final morphology of the crystals. At fast flow rates the droplets solidified rapidly and formed spherical cap structures resembling the shape of droplets, in contrast to crystal microdomains or thin films formed at slow flow rates. On a highly hydrophilic surface, the crystals formed thin film without droplets formed on the surface. We further demonstrated that by the solvent exchange crystals can be formed by using a stock solution with a very low concentration of the precursor, and the as prepared crystals can be used as seeds to trigger crystallization in bulk solution.

With the analysis of cost compared with increased performance given the range of dosages and length of supplementation in the various studies it would cost approximately $12.16 to $25.20 a month to see an increase in performance.", "corpus_id": 229116827, "venue": "", "year": 2020, "author_names": [ "William Hall" ], "n_citations": 0, "n_key_citations": 0, "score": 0 }, { "doc_id": "221724950", "title": "Beta alanine supplementation in patients with COPD receiving non linear periodised exercise training or neuromuscular electrical stimulation: protocol of two randomised, double blind, placebo controlled trials", "abstract": "Introduction Exercise intolerance is common in patients with chronic obstructive pulmonary disease (COPD) and, although multifactorial, it is largely caused by lower limb muscle dysfunction. Research has shown that patients with severe to very severe COPD have significantly lower levels of muscle carnosine, which acts as a pH buffer and antioxidant. Beta alanine (BA) supplementation has been shown to consistently elevate muscle carnosine in a variety of populations and may therefore improve exercise tolerance and lower limb muscle function. The primary objective of the current studies is to assess the beneficial effects of BA supplementation in enhancing exercise tolerance on top of two types of exercise training (non linear periodised exercise (NLPE) training or neuromuscular electrical stimulation (NMES) in patients with COPD. Methods and analysis Two randomised, double blind, placebo controlled trials have been designed. Patients will routinely receive either NLPE (BASE TRAIN trial) or NMES (BASE ELECTRIC trial) as part of standard exercise based care during their 8 to 10 week pulmonary rehabilitation (PR) programme. A total of 222 patients with COPD (2x77 154 patients in the BASE TRAIN trial and 2x34 68 patients in the BASE ELECTRIC trial) will be recruited from two specialised PR centres in The Netherlands.

The theory fell naturally out of the non Walrasian treatment there of the labor \"market\" as operating imperfectly because of the scarcity of information about the existence and characteristics of workers and jobs. A paradigm for the theory is the traveller in a strange town faced with choosing between dinner at the hotel and dinner somewhere in the town. If he makes it a rule to dine outside the hotel without any prior investigation, he is said to be discriminating against the hotel. Though there will be instances where the hotel cuisine would have been preferable, the rule represents rational behavior it maximizes expected utilityif the cost of acquiring evaluations of restaurants is sufficiently high and if the hotel restaurant is believed to be inferior at least half the time. In the same way, the employer who seeks to maximize expected profit will discriminate against blacks or women if he believes them to be less qualified, reliable, long term, etc. on the average than whites and men, respectively, and if the cost of gaining information about the individual applicants is excessive. Skin color or sex is taken as a proxy for relevant data not sampled. The a priori belief in the probable preferability of a white or a male over a black or female candidate who is not known to differ in other respects might stem from the employer's previous statistical experience with the two groups (members from the less favored groups might have been, and continue to be, hired at less favorable terms) or it might stem from prevailing sociological beliefs that blacks and women grow up disadvantaged due to racial hostility or at least prejudices toward them in the society (in which latter case the discrimination is self perpetuating) The theory is applicable to the class of \"liberal\" employers and workers who have no distaste for hiring and working alongside black or female workers. By contrast, the theory of discrimination originated by Gary Becker is based on the factor of racial taste. The pioneering work of Gunnar Myrdal et al. also appears to center on racial (and, in an appendix, sexual) antagonism. Some indications of interest in the new theory, and the independent discovery of the same statistical theoryby Kenneth Arrow, convince me that it is time for a formalization of the theory in terms of an exact statistical model. Though what follows is very simple, it may be useful to those who like exact models and it may stimulate others to develop the theory further. An employer samples from a population of job applicants. The employer is able to measure the performance of each applicant in some kind of test, yi, which, after suitable scaling, may be said to measure the applicant's promise or degree of qualification, qi, plus an error term, ps.", "corpus_id": 38504493, "venue": "", "year": 1972, "author_names": [ "Edmund S Phelps" ], "n_citations": 3120, "n_key_citations": 146, "score": 1 }, { "doc_id": "4817774", "title": "Racism as a stressor for African Americans.

We have collected cash flow data for the companies in all of the major industries of the FTSE Global All Cap index, the basis for the strategic index of the Norwegian Government Pension Fund Global.

Norway has reinvested part of the resource rent from its share of North Sea oil notably from the Ekofisk oil field (discovered in 1969) The sovereign wealth fund (Government Pension Fund Global GPFG) reached 10 000 billion NOK in 2019 [4] The fund is exclusively invested outside Norway, mainly to avoid overheating the Norwegian economy but also not to interfere with the state pension fund (Government Pension Fund Norway GPFN) Currently GPFG adheres to a policy of investing up to 70 percent of the fund in equity, up to 30 percent in fixed income and up to 7 percent in unlisted landholdings. The GPFN is invested within the country (85 percent) and the Nordic region (15 percent) [5] In 2019, the GPFN was worth 254.8 billion NOK, with 60.3 percent of the Fund invested in equities and the balance invested in fixed income securities [6] The current value of the GPFG is 7.3X government expenditure as Norway spends money at a rate of 1 377.1 billion NOK pa according to its 2019 budget [7] The GPFG is to be used by the present generation as well as to save for future generations in Norway [4] At present, Norway uses the interest and dividends generated by the GPFG to pay for the budget deficit. For 2019 'The non oil deficit is projected at NOK 232.5 billion. This deficit is fully financed through a transfer from the Government Pension Fund Global' [7] By financing the budget deficit, earnings from the CPFG enable the government to expand the economy. As the Norwegian Minister of Finance has stated, 'By cutting taxes and duties, we provide businesses and families with more economic leeway. In addition, lower taxes encourage job creation and make work more attractive.

For example, tax revenues can be large and highly volatile, and the stream of revenues is finite. An increasing number of countries now view resource funds and/or fiscal rules for resource revenues as the answer to these challenges. In this paper, we explore the consequences for the UK if past revenues arising from the depletion of subsoil assets had been channelled into a sovereign wealth fund. We show that had a decision been made to establish such a fund in 1975, this could have been substantial in size by 2018 (about GBP 354 billion) and, moreover, would have had a number of benefits such as a reduction in volatility of resource revenues flowing to the Treasury. Crucially, the fund's value would have substantially boosted the size of the government balance sheet, yielding corresponding fiscal benefits. We argue this missed opportunity is underlined further by considering the current debate about shale gas development in the UK. Notwithstanding considerable uncertainties, favourable and optimistic projections for key parameters are required for any shale based fund to match what we simulate based on past experience for conventional subsoil assets.", "corpus_id": 216298052, "venue": "", "year": 2020, "author_names": [ "Giles Atkinson", "Kirk Hamilton" ], "n_citations": 1, "n_key_citations": 0, "score": 0 }, { "doc_id": "216457985", "title": "Regulating the State Capitalism: Is There an Optimal Regulatory Model for Sovereign Wealth Fund Investment?", "abstract": "", "corpus_id": 216457985, "venue": "", "year": 2020, "author_names": [ "Wei Yin" ], "n_citations": 0, "n_key_citations": 0, "score": 1 }, { "doc_id": "230675312", "title": "Sovereign Wealth Fund (SWF) A Tool for Diversifying Nigeria's Emerging Economy", "abstract": "", "corpus_id": 230675312, "venue": "", "year": 2020, "author_names": [ "Iloanya Kenneth Okechukwu", "Nduka Christopher Ndidi" ], "n_citations": 0, "n_key_citations": 0, "score": 0 }, { "doc_id": "226557503", "title": "Investing in Sustainability: Ethics Guidelines and the Norwegian Sovereign Wealth Fund", "abstract": "", "corpus_id": 226557503, "venue": "", "year": 2020, "author_names": [ "Anita Margrethe Halvorssen", "Cody D Eldredge" ], "n_citations": 0, "n_key_citations": 0, "score": 1 }, { "doc_id": "226168190", "title": "Sovereign Wealth Fund or State Capitalism: Nigeria's Search for a Stable Economic Order", "abstract": "For quite some time now, the Sovereign Wealth Fund (SWF) has become an issue in the front burner of Nigeria's national debate.

To Melanie, who had forgotten her travelling clock who had forgotten everything the hands might have stood anywhere By the cover of Le Soleil, the Orleanist morning paper, it was 24 July 1913. Louis Philippe Robert, duc d'Orleans, was the current Pretender. Certain quarters of Paris raved under the heat of Sirius Melanie l'Heuremaudit was driven away down the rue La Fayette in a noisy auto taxi. Historical stresses underlying much twentieth century fiction are to be found in Chapter 14 of Thomas Pynchon's V. not least in the strange chronology described in its opening, quoted above, and echoed in Melanie's second name, which translates as 'the accursed hour'[1] Typically of Pynchon's fiction, those clocks seem odd but have a firm historical basis. In A la recherche du temps perdu, Proust also refers to the survival of mid European time, and even the Eastern calendar, into the early decades of the twentieth century. Within France, to help tardy travellers catch their trains, station clocks in 1913 still kept 'l'heure de la gare' five minutes slower, as Pynchon suggests, than the 'Paris time' shown on all the capital's other clocks. Belgian trains, on the other hand, still ran exactly on Brussels time, which differed from that of Paris in the early years of the century. Melanie's loss of her travelling clock at least saves her the irritation of having to reset it in the course of her journey from Belgium, a task often necessary for railway travellers in the nineteenth century and, as Pynchon shows, into the early part of the twentieth, at least on the Continent. Travelling clocks of a different sort had already ended this problem within Britain. Railway companies in the mid nineteenth century sent officials with accurate chronometers up and down the country, resetting station clocks to eliminate local times in favour of a national standard, Railway Time, established more or less throughout the land by 1848. It was further institutionalized as part of the new global standards set up by the International Meridian Conference of 1884, which answered the needs of travel, shipping, telegraphy, and other commercial interests by placing the Prime Meridian at Greenwich Observatory, also established as the centre of a world wide system of time zones and Mean Time. Contemporary public interest in the new arrangements is evident in Arthur Wing Pinero's The Magistrate, first performed the year after the Conference: when asked about the time, its hero cheerfully replies 'Hurray! Just half past ten. Greenwich mean, eh Guv? Ulysses (1922) shows Bloom pondering in 1904 the technology through which the new standard time was disseminated throughout the British Isles when he notices a Dublin time signal 'that falls at Greenwich time. It's the clock is worked by an electric wire from Dunsink'[2] Ireland, however, did not fully accept Greenwich Mean Time until 1916, and other countries were similarly tardy, France particularly. For patriotic reasons, France had always favoured Paris over Greenwich as the location of the Prime Meridian, and was consequently dilatory and eventually devious in implementing the new arrangements. GMT was legally accepted as the time of France in 1896, but it was not until fifteen years later that much was done to implement it, and even then only by referring to it as 'Paris time minus nine minutes and twenty one seconds' hence that nine minute difference from Brussels, working on GMT since 1892, which Pynchon identifies.[3] Indeed, France's official time continued to be defined in this way until 1978, when it moved to Co ordinated Universal Time, a measure (now generally accepted as the world standard at the end of the twentieth century) originally owing less to British efforts than to further conferences on time initiated by the French in Paris in 1912 and 1913.", "corpus_id": 96477296, "venue": "", "year": 2000, "author_names": [ "Randall Stevenson" ], "n_citations": 7, "n_key_citations": 0, "score": 0 }, { "doc_id": "109274421", "title": "The social dimension of the urban village: A comparison of models for sustainable urban development", "abstract": "The paper explores the social dimension of the urban village debate, by examining recent ideas on the desirable social characteristics of sustainable urban development.

Our data show decreasing magma crystallization ages both from south to north along the eastern margin of the east Himalayan syntaxis and from east to west along the Gangdese belt. We suggest that such variations resulted from the diachronous breakoff of the subducted Indian continental slab. Beneath the east Himalayan syntaxis, the breakoff of the subducted Indian continental slab was initiated in the south and propagated towards north probably due to the thermal impact of a widening window opened by slab breakoff.

The batholith dominantly consists of calc alkaline I type granitoids which are ferromagnetic in nature with the presence of magnetite as the principal carrier of magnetic susceptibility. The mesoscopic and magnetic fabric are concordant and generally vary from WNW ESE to ENE WSW for different intrusions of ferromagnetic granites in different parts of the batholith. Strike of magnetic fabric is roughly parallel with the regional trend of the Ladakh batholith in the present study area and is orthogonal to the direction of India Eurasia collision. In Khardungla and Changla section, the magnetic fabric is distributed in a sigmoidal manner. It is inferred that this sigmoidal pattern is caused by shearing due to transpression induced by oblique convergence between the two plates. U Pb zircon geochronology of a rhyolite from the southern parts of the batholith gives a crystallization age of 71.7 0.6 Ma, coeval with ~68 Ma magmatism in the northern parts of the batholith.

The magnetic fabric of these two mica granites is at a high angle to the regional trend of the batholith.

La filmografia de Disney esta basada en cuentos infantiles tradicionales, donde a traves de unos personajes cargados de actitudes estereotipadas, aparecen representados los valores, jerarquias y creencias consideradas adecuadas socialmente para los ninos y para las ninas. El proposito de este trabajo es investigar la ideologfa sexista inserta en las peliculas infantiles de la multinacional Disney para conocer como se difunden los estereotipos que construyen y condicionan la personalidad adulta y asi poner de manifiesto la intencionalidad domesticadora que tienen los medios de comunicacion, en general, y las peliculas infantiles, en particular. El estudio de los estereotipos que aparecen en los medios es una manera de visibilizar el nexo que existe entre la imagen y la ideologia; por tanto, realizando un estudio longitudinal de las representaciones femeninas de las princesas, se puede comprobar como se perpetua el orden establecido, como las relaciones de dominacion, los atropellos, los privilegios, etc. aparecen como \"condiciones de existencia\" no solo aceptables, sino desde cualquier punto de vista, naturales. Sin duda, este escenario situa a las ninas y a las mujeres en una posicion de desigualdad respecto a los ninos y a los hombres, que inevitablemente conduce a la discriminacion y que, culturalmente, se ha ido construyendo a partir de mitos, cuentos y leyendas como \"La Cenicienta\" o \"La Bella durmiente\" que, a fin de cuenta, son los que sustentan los principios de los actuales estereotipos de genero.

Motivation For over 70 years, researchers have been attempting to unravel the complexities associated with enhancing student success in higher education 1 Student success research has resulted in a better understanding of why some students decide to leave, and to some extent, why students decide to persist on to graduation. In spite of all the research that has been conducted, little work has been devoted to translating the various theoretical findings into specific strategies that will guide institutions in improving student success outcomes 2, 3 This paper is a part of a larger research effort to develop a Student Success Oriented System Design (S 2 OSD pronounced \"SAWS D\" methodology, which will integrate student success research with a growing body of knowledge on customer oriented systems approaches in order to address the following pressing need: How can institutional leaders in higher education translate the needs of their students into actionable solutions that will foster student success? In order to provide a concrete course of action for institutional leaders to design practices that meaningfully facilitate student success, institutional leaders must first have an understanding of the needs of their students. Therefore, this paper presents a framework that describes the development and the results of a pilot study to test the Student Success Oriented Needs Analysis (S 2 ONA pronounced \"SAWNA\" framework. Specifically, this paper will provide: a framework that is guided by student success theoretical perspectives; a participatory method to elicit, identify, and document student success needs; a mapping process to develop precise need statements that holistically capture a comprehensive set of engineering student needs of students; and a questionnaire to evaluate the SONA framework II.

MSA is well suited to address the rising demand for cloud applications as well as shorter and more agile development cycles [3] However, this comes at the cost of more complexity in certain areas, e.g. distributed data models or the need to prepare well defined endpoints for each service to consider possible choreography based calls from other services.

However, the influence of low level laser on polarization of macrophage/microglia following spinal cord injury remains unknown. The present study applied low level laser therapy on a crush spinal cord injury rat model. Using immunofluorescence, flow cytometry, RT qPCR, and western blot assays, we found that low level laser therapy altered the polarization state to a M2 tendency. A greater number of neurons survived in the pare injury site, which was accompanied by higher BBB scores in the LLLT group. Furthermore, low level laser therapy elevated expression of interleukin 4 (IL 4) and interleukin 13 (IL 13) Results from this study show that low level laser therapy has the potential for reducing inflammation, regulating macrophage/microglia polarization, and promoting neuronal survival.

Also, given the increasing availability and use of genetically modified animals in basic science research, it has become essential to develop clinically related models for SCI for use in mice. Methods Forty eight C57BL/6 mice were divided into three groups (injured/sham/uninjured) We determined the scar range made by the first crush injury by specimen observation, hematoxylin and eosin (HE) staining, and immunofluorescence staining. Transection to completely remove a 2 mm spinal cord segment centered on the lesion core was completed 6 weeks after the first injury in injured groups, whereas the sham group only underwent re exposure of the spinal cord without transection injury. The characteristics of this SCI model were fully ascertained by specimen observation, HE staining, immunofluorescence staining, and quantitative real time polymerase chain reaction (qRT PCR) Results No mice died after the first injury. Histopathological findings suggested a scar range of 2 mm. After the second operation, 2 mice of the injured group and 1 mouse of the sham group died. The Basso Mouse Scale (BMS) score and motor evoked potential (MEP) results showed that the neurological function of mice did not recover. Immunostaining showed that there were no neurons or neurofilament residues in the lesion core 4 weeks after the second injury. Astrocytes encapsulated immune cells to form dense glial scars. Most immune cells were confined to the core of the lesion and formed fibrous scars with the fibroblasts. At the same time, there was considerable angiogenesis in the lesion core and around the injury. The results of qRT PCR showed that Ptprc was highly expressed in the lesion core, while Gfap, nestin, Cnp, and Sv2b were highly expressed in the adjacent region. This suggests that the lesion core is a highly inflammatory zone, but there may be spontaneous neurogenesis adjacent to the lesion core.

It has been proved that the crucial factor in triggering this upregulation is proinflammatory cytokines. Moreover, scar formation is an important barrier to axonal regeneration through the lesion area. Melatonin plays an important role in reducing inflammation, but its effects on scar formation in the injured spinal cord remain unknown. Hence, we used the model of severe crush injury in mice to investigate the effects of melatonin on scar formation. Mice were randomly separated into four groups; SCI, SCI+Melatonin 1 (single dose) SCI+Melatonin 14 (14 daily doses) and control. Melatonin was administered by intraperitoneal injection (10 mg/kg) after injury. Immunohistochemical analysis, Western blot, and behavioral evaluation were used to explore the effects of melatonin after SCI for 14 days. The melatonin treated mice presented higher expression of neuronal markers (P 0.001) Remarkably, the inflammatory response appeared to be greatly reduced in the SCI+Melatonin 14 group (P 0.001) which also displayed less scar formation (P 0.05) These findings suggest that melatonin inhibits scar formation by acting on inflammatory cytokines after SCI.

This process, which actively involves glial cells, is influenced by the expression of immune related molecules. Since toll like receptors (TLRs) are upregulated by astrocytes and microglia following lesions, they might be involved in synaptic plasticity processes. Therefore, we administered lipopolysaccharide (LPS) to enhance TLR4 expression in mice and studied retrograde changes in the spinal cord ventral horn following sciatic nerve crush. To this end, adult C57BL/6 J male mice were subjected to unilateral sciatic nerve crush at the mid thigh level and, after a survival time of seven and forty days (acute and chronic phases, respectively) the spinal cords were paraformaldehyde fixed and dissected out for immunolabeling for synaptophysin, glial fibrillary acidic protein (GFAP) and ionized calcium binding adapter molecule 1 (Iba1) The results show that TLR4 upregulation leads to synaptophysin downregulation close to spinal motoneuron cell bodies, indicating increased synaptic elimination. LPS exposure also further increases astrogliosis and microglial reactions in the both ventral and dorsal horns, especially ipsilateral to nerve axotomy, compared to those in untreated mice. Notably, LPS administration to TLR4 mice produces results similar to those observed in untreated wild type counterparts, reinforcing the role of this receptor in the glial response to injury. Therefore, our results suggest that the overexpression of the TLR4 receptor results in augmented astrogliosis/microglial reactions and the excessive loss of synapses postinjury, which may, in turn, affect the motoneuronal regenerative response and functionality. Additionally, treatment with LPS increases the expression of b2 microglobulin, a subcomponent of MHC I. Importantly, the absence of TLR4 results in imbalanced axonal regeneration, inducing subsequent improvements and setbacks.

Briefly, each mouse was subjected to laminectomy of T5 T7, 15 second spinal cord crush using one of those forceps, behavioral assessments, and post mortem neuroanatomical analyses. There were significant differences among the three injury severity groups on behavioral measures (Basso Mouse Score, footprint, and ladder analyses) demonstrating an increase in neurological deficits for groups with greater injury severity. Quantitative analysis of the lesion demonstrated that as injury severity increased, lesion size and GFAP negative area increased, and spared tissue, spinal cord cross sectional area, spared grey matter and spared white matter decreased. These measures strongly correlated with the behavioral outcomes.

Previous infections cleared in all infants, and all continued to grow normally. IgM levels normalized in seven of the eight infants, of whom four discontinued intravenous immune globulin supplementation; three of these four infants had a response to vaccines. Vector insertion site analysis was performed in seven infants and showed polyclonal patterns without clonal dominance in all seven. CONCLUSIONS Lentiviral vector gene therapy combined with low exposure, targeted busulfan conditioning in infants with newly diagnosed SCID X1 had low grade acute toxic effects and resulted in multilineage engraftment of transduced cells, reconstitution of functional T cells and B cells, and normalization of NK cell counts during a median follow up of 16 months.

METHODS The primary objective of the study was to compare progression free survival with conditioning of busulfan plus melphalan with melphalan alone in patients with multiple myeloma. Patients with newly diagnosed multiple myeloma who were eligible for cell transplantation, aged 70 years or younger, with at least stable disease, were randomly assigned (1:1) to treatment. Patients received either busulfan plus melphalan, with a test dose of busulfan 32 mg/m2 followed by pharmacokinetically adjusted doses on days 7, 6, 5, and 4 to achieve a target daily area under the curve (AUC) of 5000 mmol minute and melphalan 70 mg/m2 per day on days 2 and 1 (total melphalan dose 140 mg/m2) or a melphalan dose of 200 mg/m2 on day 2. Randomisation was performed via a Clinical Trial Conduct Website at the University of Texas MD Anderson Cancer Center. The accrual is complete and final results are presented here. The study is registered with ClinicalTrials.gov, number NCT01413178. FINDINGS Between Oct 12, 2011, and March 22, 2017, 205 patients were assessed for eligibility and randomly assigned to treatment. The primary analysis of progression free survival was measured in 202 patients who received treatment: 104 patients in the busulfan plus melphalan group and 98 patients in the melphalan alone group. 90 days after auto HCT, 102 (98% of 104 patients given busulfan plus melphalan and 95 (97% of 98 patients given melphalan alone achieved partial response or better. The median follow up in the busulfan plus melphalan group was 22*6 months (IQR 15*2 47*1) and 20*2 months (IQR 8*8 46*6) in the melphalan alone group. Median progression free survival was 64*7 months (32*9 64*7) with busulfan plus melphalan versus 43*5 months (19*9 not estimated) with melphalan alone (hazard ratio 0*53 [95% CI 0*30 0*91] p=0*022) There were no treatment related deaths by day 100 in either group. Grade 2 3 mucositis was observed in 77 (74% of 104 patients in the busulfan plus melphalan group versus 14 (14% of 98 patients in the melphalan alone group. INTERPRETATION These findings, if confirmed in other ongoing studies, suggest that busulfan plus melphalan could replace melphalan alone as the conditioning regimen for auto HCT in patients with newly diagnosed myeloma.

METHODS We did an open label, randomised, non inferiority, phase 3 trial in 31 transplantation centres in France, Germany, Hungary, Italy, and Poland. Eligible patients were 18 70 years, had acute myeloid leukaemia in first or consecutive complete haematological remission (blast counts <5% in bone marrow) or myelodysplastic syndrome (blast counts <20% in bone marrow) Karnofsky index of 60% or higher, and were indicated for allogeneic HSCT but considered at an increased risk for standard myeloablative preparative regimens based on age =50 years) an HSCT specific comorbidity index of more than 2, or both. Patients were randomly assigned (1:1) to receive either intravenous 10 g/m2 treosulfan daily applied as a 2 h infusion for 3 days (days 4 to 2) or 0*8 mg/kg busulfan applied as a 2 h infusion at 6 h intervals on days 4 and 3. Both groups received 30 mg/m2 intravenous fludarabine daily for 5 days (days 6 to 2) The primary outcome was event free survival 2 years after HSCT. The non inferiority margin was a hazard ratio (HR) of 1*3. Efficacy was assessed in all patients who received treatment and completed transplantation, and safety in all patients who received treatment. The study is registered with EudraCT (2008 002356 18) and ClinicalTrials.gov (NCT00822393) FINDINGS Between June 13, 2013, and May 3, 2016, 476 patients were enrolled (240 in the busulfan group received treatment and transplantation, and in the treosulfan group 221 received treatment and 220 transplanation) At the second preplanned interim analysis (Nov 9, 2016) the primary endpoint was met and trial was stopped. Here we present the final confirmatory analysis (data cutoff May 31, 2017) Median follow up was 15*4 months (IQR 8*8 23*6) for patients treated with treosulfan and 17*4 months (6*3 23*4) for those treated with busulfan. 2 year event free survival was 64*0% (95% CI 56*0 70*9) in the treosulfan group and 50*4% (42*8 57*5) in the busulfan group (HR 0*65 [95% CI 0*47 0*90] p<0*0001 for non inferiority, p=0*0051 for superiority) The most frequently reported grade 3 or higher adverse events were abnormal blood chemistry results (33 [15% of 221 patients in the treosulfan group vs 35 [15% of 240 patients in the busulfan group) and gastrointestinal disorders (24 [11% patients vs 39 [16% patients) Serious adverse events were reported for 18 (8% patients in the treosulfan group and 17 (7% patients in the busulfan group.

We aimed to assess event free survival after high dose chemotherapy with busulfan and melphalan compared with carboplatin, etoposide, and melphalan. METHODS We did an international, randomised, multi arm, open label, phase 3 cooperative group clinical trial of patients with high risk neuroblastoma at 128 institutions in 18 countries that included an open label randomised arm in which high dose chemotherapy regimens were compared. Patients (age 1 20 years) with neuroblastoma were eligible to be randomly assigned if they had completed a multidrug induction regimen (cisplatin, carboplatin, cyclophosphamide, vincristine, and etoposide with or without topotecan, vincristine, and doxorubicin) and achieved an adequate disease response. Patients were randomly assigned (1:1) to busulfan and melphalan or to carboplatin, etoposide, and melphalan by minimisation, balancing age at diagnosis, stage, MYCN amplification, and national cooperative clinical group between groups.

Based on previous theoretical considerations and empirical findings, we suggest an Interaction of Person Affect Cognition Execution (I PACE) model of specific Internet use disorders. The I PACE model is a theoretical framework for the processes underlying the development and maintenance of an addictive use of certain Internet applications or sites promoting gaming, gambling, pornography viewing, shopping, or communication. The model is composed as a process model. Specific Internet use disorders are considered to be the consequence of interactions between predisposing factors, such as neurobiological and psychological constitutions, moderators, such as coping styles and Internet related cognitive biases, and mediators, such as affective and cognitive responses to situational triggers in combination with reduced executive functioning.

Drawing conclusions about the impact of the digital world on loneliness is difficult because there are contradictory findings, and cross sectional studies dominate the literature, making causation difficult to establish. In this review, we present our theoretical model and propose that there is a bidirectional and dynamic relationship between loneliness and social Internet use. When the Internet is used as a way station on the route to enhancing existing relationships and forging new social connections, it is a useful tool for reducing loneliness. But when social technologies are used to escape the social world and withdraw from the \"social pain\" of interaction, feelings of loneliness are increased. We propose that loneliness is also a determinant of how people interact with the digital world. Lonely people express a preference for using the Internet for social interaction and are more likely to use the Internet in a way that displaces time spent in offline social activities. This suggests that lonely people may need support with their social Internet use so that they employ it in a way that enhances existing friendships and/or to forge new ones.", "corpus_id": 10175734, "venue": "Perspectives on psychological science a journal of the Association for Psychological Science", "year": 2018, "author_names": [ "Rebecca Nowland", "Elizabeth A Necka", "John T Cacioppo" ], "n_citations": 173, "n_key_citations": 4, "score": 1 }, { "doc_id": "52986097", "title": "A review of Internet use among older adults", "abstract": "As the world population ages and older adults comprise a growing proportion of current and potential Internet users, understanding the state of Internet use among older adults as well as the ways their use has evolved may clarify how best to support digital media use within this population.

Thus, the internet has become a great resource for supporting youth self care and health related services. However, few studies have explored adolescents' internet use for health related matters. Objective The objective of this systematic literature review was to examine the phenomenon of children and adolescents' health related internet use and to identify gaps in the research. Methods A total of 19 studies were selected from a search of major electronic databases: PubMed, Cumulative Index of Nursing and Allied Health Literature, and PsycINFO using the following search terms: \"health related internet use,\" \"eHealth,\" \"Internet use for health related purpose,\" \"Web based resource,\" \"health information seeking,\" and \"online resource,\" combined with \"child,\" \"adolescent,\" \"student,\" \"youth,\" and \"teen.\" The children's and adolescents' ages were limited to 24 years and younger.

Studies were excluded if they explored the role of the internet as a modality for surveys, recruitment, or searching for relevant literature without specifically aiming to study participants' health related internet use; focused solely on quality assurance for specific websites; or were designed to test a specific internet based intervention. Results Interesting patterns in adolescents' health related internet use, such as seeking preventative health care and specific information about medical issues, were identified. Quantitative studies reported rates of the internet use and access among youth, and the purpose and patterns of health related internet use among youth were identified. A major objective of health related internet use is to gain information, but there are inconsistencies in adolescents' perceptions of health related internet use.

We aimed to systematically review evidence regarding the potential influence of the internet on self harm/suicidal behaviour in young people. Methods We conducted a systematic review based on an electronic search for articles published between 01/01/2011 and 26/01/2015 across databases including Medline, Cochrane and PsychInfo. Articles were included if: the study examined internet use by individuals who engaged in self harm/ suicidal behaviour, or internet use clearly related to self harm content; reported primary empirical data; participants were aged under 25 years. New studies were combined with those identified in a previous review and subject to data extraction, quality rating and narrative synthesis. Results Forty six independent studies (51 articles) of varying quality were included. Perceived influences were: positive for 11 studies (38191 participants) negative for 18 studies (119524 participants) and mixed for 17 studies (35235 participants) In contrast to previous reviews on this topic studies focused on a wide range of internet mediums: general internet use; internet addiction; online intervention/treatment; social media; dedicated self harm websites; forums; video/image sharing and blogs. A relationship between internet use and self harm/suicidal behaviour was particularly associated with internet addiction, high levels of internet use, and websites with self harm or suicide content. While there are negative aspects of internet use the potential for isolation reduction, outreach and as a source of help and therapy were also identified. Conclusions There is significant potential for harm from online behaviour (normalisation, triggering, competition, contagion) but also the potential to exploit its benefits (crisis support, reduction of social isolation, delivery of therapy, outreach) Young people appear to be increasingly using social media to communicate distress, particularly to peers. The focus should now be on how specific mediums' (social media, video/image sharing) might be used in therapy and recovery. Clinicians working with young people who self harm or have mental health issues should engage in discussion about internet use. This should be a standard item during assessment.

METHODS Over the last 15 years, the number of Internet users has increased by 1000% and at the same time, research on addictive Internet use has proliferated. Internet addiction has not yet been understood very well, and research on its etiology and natural history is still in its infancy. In 2013, the American Psychiatric Association included Internet Gaming Disorder in the appendix of the updated version of the Diagnostic and Statistical Manual for Mental Disorders (DSM 5) as condition that requires further research prior to official inclusion in the main manual, with important repercussions for research and treatment. To date, reviews have focused on clinical and treatment studies of Internet addiction and Internet Gaming Disorder. This arguably limits the analysis to a specific diagnosis of a potential disorder that has not yet been officially recognised in the Western world, rather than a comprehensive and inclusive investigation of Internet use related addictions (including problematic Internet use) more generally. RESULTS The systematic literature review identified a total of 46 relevant studies. The included studies used clinical samples, and focused on characteristics of treatment seekers and online addiction treatment. Four main types of clinical research studies were identified, namely research involving (1) treatment seeker characteristics; (2) psychopharmacotherapy; (3) psychological therapy; and (4) combined treatment.

This study examines whether the Dating Matters comprehensive prevention model, compared with a standard of care intervention, prevented negative relationship behaviors and promoted positive relationship behaviors. Study design: This longitudinal, cluster RCT compared the effectiveness of Dating Matters with standard of care across middle school. Standard of care was an evidence based teen dating violence prevention curriculum (Safe Dates) implemented in eighth grade. Setting/participants: Forty six middle schools in high risk urban neighborhoods in four U.S. cities were randomized. Schools lost to follow up were replaced with new schools, which were independently randomized (71% school retention) Students were surveyed in fall and spring of sixth, seventh, and eighth grades (2012 2016) The analysis sample includes students from schools implementing Dating Matters or standard of care for >2 years who started sixth grade in the fall of 2012 or 2013 and had dated (N=2,349 students, mean age 12 years, 49% female, and 55% black, non Hispanic, 28% Hispanic, 17% other) Intervention: Dating Matters is a comprehensive, multicomponent prevention model including classroom delivered programs for sixth to eighth graders, training for parents of sixth to eighth graders, educator training, a youth communications program, and local health department activities to assess capacity and track teen dating violence related policy and data. Main outcome measures: Self reported teen dating violence perpetration and victimization, use of negative conflict resolution strategies, and positive relationship skills were examined as outcomes. Imputation and analyses were conducted in 2017. Results: Latent panel models demonstrated significant program effects for three of four outcomes; Dating Matters students reported 8.43% lower teen dating violence perpetration, 9.78% lower teen dating violence victimization, and 5.52% lower use of negative conflict resolution strategies, on average across time points and cohorts, than standard of care students. There were no significant effects on positive relationship behaviors. Conclusions: Dating Matters demonstrates comparative effectiveness, through middle school, for reducing unhealthy relationship behaviors, such as teen dating violence and use of negative conflict resolution strategies, relative to the standard of care intervention.

From an initial sample of 1,038 Spanish adolescents, those who had or had had in the past 12 months a dating relationship (647 adolescents; 49.1% boys, M 14.38, SD 1.43) were included in this study. Multigroup structural equation modeling was used to test a double mediation model simultaneously for boys and girls, testing the invariance of the relationships among variables across genders. The same technique was used to test the model simultaneously for early and middle adolescence, testing the invariance of the relationships among variables across age groups. Results revealed a positive direct relationship between peer victimization and dating violence victimization, as well as the partial mediating role of loneliness and life satisfaction in this relationship. The mediator role of depressed mood was not supported. The same mediational model was confirmed in boys and girls, and in early and middle adolescence. These results highlight the important role of loneliness and life satisfaction to explain the link between peer victimization and dating violence victimization in adolescence. These findings may be useful for developing intervention programs aimed at preventing situations of multiple victimization during adolescence.", "corpus_id": 3878034, "venue": "Journal of interpersonal violence", "year": 2018, "author_names": [ "Maria-Jesus Cava", "Sofia Buelga", "Ines Tomas" ], "n_citations": 24, "n_key_citations": 0, "score": 0 } ]

Generally, heart diseases are considered life style associated diseases but many other factors are also found associated with cardiovascular diseases. OBJECTIVE The aim of this review is to provide the till date information regarding local and circulatory disorders, role of different vitamin and herbs on heart diseases. METHODS This review article contains a detailed survey of literature about cardiovascular diseases which was available in different online databases such as; PubMed, Web of Science, Science Direct, Elsevier, and Google Scholar etc. In this review, authors have focused on description of cardiovascular disorders, their pathophysiological properties and importance of micronutrients, vitamins and herbs in management of cardiovascular diseases. RESULTS Cardiovascular diseases are considered the responsible approximately for 17.9 million deaths annually at global level. Surprisingly, low and middle income countries counts for 75% of CVD deaths. These diseases represents disorders related circulatory systems specially heart and coronary arteries. Many life style associated factors such as; high cholesterol consumption, smoking, alcohol consumption, tobacco use, metabolic disorders, stress, and other factors such as; family history, age, gender and genetic factors etc have been found involved in establishment of CVDs. That's why management of diet, management of tobacco and alcohol consumption, management of stress, increased physical activities are considered population wide strategies for control cardiovascular diseases. On the basis of pathophysiology, heart diseases are of many types and out of them acute myocardial infarction (AMI) and sudden cardiac death (SCD) are considered serious and catastrophic cardiac disorders. Intake of vitamins, micronutrients, lycopene, omega 3 fatty acid and many herbs like Crataegus oxyacantha (Hawthron) Allium sativum (garlic) Salvia miltiorrhiza (Danshen) Ganoderma lucidum (lingzhi) Ginkgo biloba have been identified good for cardiovascular diseases management and treatment. CONCLUSION Cardiovascular dieseases are considered one of the fatal clinical conditions as many of them are asymptomatic. The regulation of diet, increased physical activities, and health life style are recommened to control development of cardiovascular problems.

In response to the COVID 19 situation, Jordan announced the emergency state on the 19th of March, followed by the curfew on 21 March. All educational institutions have been closed as well as educational activities including clinical medical education have been suspended on the 15th of March. As a result, Distance E learning emerged as a new method of teaching to maintain the continuity of medical education during the COVID 19 pandemic related closure of educational institutions. Distance E Learning is defined as using computer technology to deliver training, including technology supported learning either online, offline, or both. Before this period, distance learning was not considered in Jordanian universities as a modality for education. This study aims to explore the situation of distance E learning among medical students during their clinical years and to identify possible challenges, limitations, satisfaction as well as perspectives for this approach to learning. Methods This cross sectional study is based on a questionnaire that was designed and delivered to medical students in their clinical years. For this study, the estimated sample size n 588) is derived from the online Raosoft sample size calculator. Results A total of 652 students have completed the questionnaire, among them, 538 students (82.5% have participated in distance learning in their medical schools amid COVID 19 pandemic. The overall satisfaction rate in medical distance learning was 26.8% and it was significantly higher in students with previous experience in distance learning in their medical schools as well as when instructors were actively participating in learning sessions, using multimedia and devoting adequate time for their sessions. The delivery of educational material using synchronous live streaming sessions represented the major modality of teaching and Internet streaming quality and coverage was the main challenge that was reported by 69.1% of students. Conclusion With advances in technologies and social media, distance learning is a new and rapidly growing approach for undergraduate, postgraduate, and health care providers. It may represent an optimal solution to maintain learning processes in exceptional and emergency situations such as COVID 19 pandemic.

The Ministry of Education and Culture (MOEC) and the Ministry of Religious Affairs (MORA) need to consider distance learning approaches that are adjusted to regional characteristics. Distance learning exacerbates barriers of vulnerable students to access education, so diversification of the delivery medium beyond the Internet should be considered. Options may include radio programs or postal services for regions with low connectivity. Local governments need to take on a more active role in aiding the schools than initiatives by the central government. In addition to using existing School Operational Assistance (Bantuan Operasional Sekolah/BOS) funds, local education authorities need to provide schools with further financial support and technical assistance, such as access to recording studios and equipment, to accelerate their adoption of distance learning. Such assistance should not neglect private community schools. Indonesia needs to embark on a large scale capacity building program to better execute distance learning across regions. This requires updating the strategy and supervision on BOS utilization, upgrading capacities of school principals and allowing them to assume greater autonomy at schools, and equipping teachers with hard and soft skills for distance learning.

A validated questionnaire was developed to collect the relevant data for this study. The initial reliability test obtained 8.9 Cronbach's alpha. Data gathering procedure was done through Google forms, which, after validation from the respective DepEd divisions and universities, were subsequently sent to the teachers via email. The results show that the teachers were highly aware of the presence and consequences caused by the COVID 19 pandemic. The correlation between teacher's demographic profiles and awareness to COVID 19 shows no relationship at all. Nevertheless, the length of teaching experience and specialization is very strongly correlated to readiness to distance learning education. Simultaneously, the teachers' geographic location is strongly correlated to readiness to adapt to distance learning education. Furthermore, only the teachers' gender has a significant difference in their awareness of the COVID 19 pandemic. In contrast, teachers' gender, length of teaching experience, and geographic location have significant differences with their readiness to distance learning education.

Using the common middleware, we conducted experiments to study the performance of MQTT and CoAP in terms of end to end delay and bandwidth consumption. Experimental results reveal that MQTT messages have lower delay than CoAP messages at lower packet loss rates and higher delay than CoAP messages at higher loss rates.

IoT services are a key solution for providing smart environments in homes, buildings, and cities. In the era of massive number of connected things and objects with high growth rate, several challenges have been raised, such as management, aggregation, and storage for big produced data. To address some of these issues, cloud computing emerged to the IoT as Cloud of Things (CoT) which provides virtually unlimited cloud services to enhance the large scale IoT platforms. There are several factors to be considered in the design and implementation of a CoT platform. One of the most important and challenging problems is the heterogeneity of different objects. This problem can be addressed by deploying a suitable \"middleware\" which sits between things and applications as a reliable platform for communication among things with different interfaces, operating systems, and architectures. The main aim of this paper is to study the middleware technologies for CoT. Toward this end, we first present the main features and characteristics of middlewares.

It is asserted that the existing methodologies (DEMO Design and Engineering Methodology for Organizations, BORM Business Object Relation Modeling and OntoUML) provide tools for analysis of the organization and its business processes through different ways. They lead to different results and make the process of organization modeling complicated. There is no software to support work with these methodologies together. The purpose of this research is to create a unified meta model (within the Eclipse EMF technology) for a new methodology based on the existing ones and to analyze the completeness of these methodologies for describing enterprise architecture. It will serve as a basis for a new open software platform for multifaceted modeling of the organization. In this research, we have compared the above mentioned methodologies and concluded that despite the fact that these methodologies provide an analysis of different aspects of organizational structure, they have a common basic set of concepts. This study demonstrates the implementation of the Ecore model that is built on the basis of the selected group of common elements of these methodologies. We have also found that the combination of the considered methodologies contains all the concepts inherent in the systematic approach to the modeling of organizational structure. Furthermore, we have demonstrated the aspects of the organization that can be modeled by the methodologies considered. Using the Zachman framework, it was shown that: the DEMO, BORM and OntoUML methodologies allow us to describe in detail the business processes that take place at different levels of the organization, from the ontological to the datalogical, and therefore provide comprehensive information for the multifaceted modeling of an organization.

Participants consisted of 113 undergraduate students (45 male, 68 female) with ages ranging from 18 33 (M= 21.12, SD= 1.81) A quantitative survey design was chosen, with cross sectional and correlational components. Participants completed an online questionnaire containing four questionnaires including Bergen Social Media Usage Scale, Body Shape Questionnaire, Godin Leisure Scale and the Adult Eating Behaviours Questionnaire. The analysis revealed males were found to have higher body image satisfaction than their female counterparts. There was a significant positive correlation between body image satisfaction and exercise, and between body image satisfaction and positive eating habits. Body image satisfaction was significantly positively correlated social media usage. Body image satisfaction was found to significantly predict social media usage. 6 Introduction It is difficult to believe that a little over a decade ago social media was in its early years and had not yet gained traction. While a couple of decades ago vast sums of money would be spent on phone calls, and months would be spent waiting for letters, this has all changed partially due to social media. Social media has completely changed the way in which people communicate with one another; it has erased geographical boundaries that were once present. It has not only changed the way in which people communicate, it has also changed what and how much information can be accessed. This may not always be a good thing, as being exposed to all this information can lead to unrealistic expectations and notions of what is the norm. Advertising in recent years has been portraying what the media believe to be the ideal in many different aspects of life, i.e. the ideal car, the ideal home, the ideal body type. The ideal body type is an aspect of advertising on social media that can have extremely harmful effects on the public. In recent years substantial levels of body dissatisfaction have been reported (Levine Smolak, 2000) Research in the US suggests approximately 40% of adolescent girls are dissatisfied with their bodies (Presnell, Bearman, Stice, 2004) Similarly amongst UK samples, 48% reported to be dissatisfied with their shape, with 22% reporting that they were too fat (Sands Wardle, 2003) and these figures only increase with age, as 50% of 11 16 reported being dissatisfied (White Halliwell, 2010) Although the vast majority of research has focused on females; the attention on male body image has seen a steady increase (Pope, Phillips and Olivardia, 2000) In a society, which places heavy emphasis on physical appearance, could the presence of social media be to blame for these recent increases? Research has shown convincing evidence that the unrealistic body image ideals displayed in the media can lead to body dissatisfaction (Grabe, Ward, Hyde, 2008) 7 The Media's portrayal of men and women In recent decades the media has been the primary source of what the public see, in the past this content was conveyed through mediums such as television, newspapers and magazines, these forms are a slightly less prevalent due to the launch of the Internet. The media is now more reliant on the Internet and information technology for conveying its message to the public. The Internet has changed what and how much is seen; it is responsible for vast amounts of information. Social media is highly visual and interactive; many social media platforms are based on a currency of likes and followers. Sherman et al, (2016) conducted a study using a social media platform similar to the photo sharing app Instagram, in which 32 adolescents between 11 16 were asked to take part. Upon receiving high numbers of likes on their photos, there was a high level of activity seen across a wide variety of regions of the brain. A part of the striatum (nucleus accumbens) which is part of the brain's reward circuitry, was especially active, this shows that likes from a social media platform translate to a level of achievement in the brain. This study also reported that when shown the exact same photo with a lot of likes to half the participants and a just a few likes to the other half, they were significantly more likely to like it themselves in the photo with more likes. Teens react differently to information when they believe many endorse it. Social media networking is the primary way young people connect and communicate, it can be considered their main channel to the outside world. It has been previously reported that greater usage of sexually objectifying media may be associated with higher levels of self objectification (Aubrey Frisby, 2011; Baker, 2005) Social media allows its user to see the world through a filter rather than real life. It is largely responsible for what the public sees as the ideal man and 8 woman (McCabe et al. 2007) Many of the advertisements that use social media as a medium to convey their message put heavy emphasis on physical appearance and the importance of being considered physically attractive, this in turn puts pressure on men and women to conform to these unattainable standards that have been set. McCabe et al, (2007) reported that these advertisements might have unfavourable effects on both men and women, noting that women are more susceptible to these effects. From a young age unattainable standards are constantly presented, beginning with every young girls beloved Barbie. An eating awareness campaign by Slayen (2011) constructed a life size Barbie according to her doll size measurements. The life size Barbie showed shocking dimensions, including an 18inch waist. If this Barbie were a real person it was reported that she would walk on all fours, with a BMI of 16.24 which would be considered anorexic, putting her at high risk of osteoporosis, amenorrhea (not being able to menstruate) and low heart rate. In the 1940's the ideal for women was to have a large bust and small waist, at the time Marilyn Monroe was the pinnacle of sexiness and her measurements now would be ones that would be fat shamed. This quickly changed in the 1960s, curves were no longer important and the look to have was one that could be considered an emaciated look. Between the years of 1960 and 1980 research has shown that the female body shown in the media has become smaller and smaller (Grogan, 2008) In the past there was not as much pressure on men as there was on women, but in recent years this has changed. As women are gaining financial power, which they did not have in the past, men now have to bring more to the table. In 2012 CNN (Strickland, 2012) reported 'in addition to being financially successful, they need to be well groomed, in good shape, emotionally skilled in relationships and 9 the emphasis on looking good is just part of the bigger packagethe stakes have been raised' (Stickland, 2012) Over centuries there has been a drastic change in what has been the ideal male body, in roman times 800 BC the ideal was considered to be a body that would now be considered overweight, this was the ideal at the time as it showed that the male had substantial means to feed himself. Recent empirical research shows a man's desire to increase muscularity (Morrison Morrison, 2006) From an evolutionary perspective humans develop psychological mechanisms to find a potential mating partner who is reproductively fit (Cosmides Tooby, 1992) For men their physique conveys information about their reproductive fitness, a male who is muscular, strong and large is deemed to have the most vigorous set of genes (Singh, 1995) Those who process these preferences are more successful in their reproductive goals. This places great emphasize on being physically fit and muscular. This importance has only increased in recent years, with popular films such as 'Rocky' and 'Rambo' having their protagonist as an extremely muscular man. Social Media Since the launch of MySpace in 2003, as one of the world first social networking sites, they (Social networking sites) have only become more plentiful. Following MySpace, Facebook, YouTube, Instagram, Twitter and Snapchat have emerged. Millions of new people are joining every year; between 2012 and 2017 Facebook's users grew from 1 billion to 2 billion users. (Constine, 2017) Recent figures have shown that monthly rates for social networking sites are at an all time high, with Facebook, YouTube, Instagram, Twitter and Snapchat being the leaders, with users' monthly presence at 2 billion, 1.5 billion, 700 million, 328 million and 255 million, respectively.

Despite the numerous studies on the effect traditional media has on body image, very few have focused on the effect of newer forms of media (e.g. online media) And almost none have looked at the relationship between time spent online and body image. Aim To study the associations between time spent on the internet, body image satisfaction and eating behaviors of students grades 7 to 12 in the Thai educational system. Methods The sample group included 620 students, who were selected using simple random sampling from 6 secondary schools in Bangkok. Data were collected using the Media and Internet use behavior questionnaires, The Body Esteem Scale for Adolescents and Adults: Thai version (BESAA) Drive for Muscularity Scale (DMS: males only) The Rosenberg Self Esteem Scale: Thai version, Eating Attitude Test 26: Thai version (EAT 26) and the eating behaviors at risk of obesity questionnaire.

Most of this past research has been conducted on traditional media formats (e.g. magazines, television) but much less is known about the impact that social media has on women's body image. This program of research used a mixed methods approach to examine the relationship between social media usage (particularly Facebook) and body image concerns among young women, as well as the role of appearance comparisons in that relationship. Correlational studies found that Facebook usage was positively associated with body image concerns (in Study 1) and self objectification (in Study 2) and that these relationships were mediated by young women's tendency to make appearance comparisons, particularly to peers on Facebook. In an experimental study (Study 3) brief exposure to Facebook had no impact on women's appearance concerns. However, spending even a brief amount of time on Facebook put women in a more negative mood, and for women who were high on appearance comparison tendency, spending time on Facebook made them more concerned about certain aspects of their face, hair, or skin. Study 4 used ecological momentary assessments to examine the frequency and impact of appearance comparisons through social media and other mediums (e.g. traditional media, in person) in women's everyday lives. Women reported more appearance comparisons through social media than any other media type (e.g. magazines, television) and the majority of comparisons made through social media were upward in direction. Furthermore, upward comparisons through social media were associated with the most negative mood, and were associated with less appearance satisfaction and more thoughts of dieting and exercising than were comparisons made in person. These findings highlight the important role of appearance comparisons through social media on young women's body image. Given the popularity of social media, and the potential negative impact it has on its users, it will be important for future research to identify ways to minimise any negative influence of social media usage.", "corpus_id": 148759185, "venue": "", "year": 2016, "author_names": [ "Jasmine Fardouly" ], "n_citations": 0, "n_key_citations": 0, "score": 0 }, { "doc_id": "222107483", "title": "Facebook's Effect on Relationships and Self Esteem", "abstract": "Much research has shown a pattern between low satisfaction within relationships and low self esteem due to Facebook usage, but there is little research done on how Facebook affects romantic relationships in terms of self esteem and negative emotions. This study examined these constructs. La Salle undergraduates between the ages of 18 21, both male and female, who are in committed relationships, were recruited. Measurements presented via Qualtrics included Facebook usage levels, relationship satisfaction, relationship conflicts, and self esteem assessments. The findings indicated that Facebook usage has no impact on the romantic relationship satisfaction levels or self esteem scores, but associations between negative impacts on Facebook and relational issues were significant. Facebook's effect on relationships and self esteem Ortiz 3 Facebook's effect on relationships and self esteem Relationships are constantly changing in ways that not many of us realize and our selfesteem levels are impacted as well. What if social media is one of the causes of these changes? The online world is extremely prevalent in our lives in variety of ways. We use social media for jobs, school, personal uses, and it has become part of our daily activities. Romantic relationships are an example of social media's compelling influence. Facebook is just one out of the many social networking sites that we use as a platform to create, develop, and keep our relationships together. Romantic relationships can become an issue when Facebook engagement is relatively high. There can be some potential negative outcomes on a romantic relationship in many ways (Kerkhof, Finkenauer, Muusses, 2011) Breakups, communication, jealousy, and Facebook intrusion are examples of some potential outcomes from someone's involvement in Facebook. There have been numerous studies done to measure Facebook's impact on romantic relationships, as well as studies that focused on Facebook's effects on self esteem. What we know from previous studies is that high social media usage can be problematic to psychological well being (Naeemia, Tamam Hassan, Bolong, 2014) Studies have shown that satisfaction levels for relationships are more likely to be negative when engaging into Facebook specific conflicts that can damage the relationship. Some concerns that arise from this issue could be: Are our relationships satisfaction decreasing from our media usage? Does Facebook related activities influence our romantic relationships? This can create a barrier between a healthy and unhealthy relationship with a significant other. Facebook can also cause some negative emotional responses. Jealousy and self consciousness can erupt from the pressures of social media (Elphinston Noller, 2011) Facebook's effect on relationships and self esteem Ortiz 4 A study was done by Clayton and his colleagues (2013) to examine if Facebook is to blame for relationship breakups. In their research, they measured the usage of Facebook from 205 users of an 18 82 year population. In their study, it was concluded that the majority of their sample use Facebook extensively. Their survey questioned if there was any relationship conflicts that occurred while Facebook was actively being used. The results consisted of communication issues and jealousy that came from monitoring their partner online. These Facebook related conflicts in their study mediated the negative relationships outcomes and Facebook usage. It is safe to conclude that in this study, negative impacts on relationships resulted from Facebook usage (Clayton. Nagurney, Smith, 2013) Negative impacts might include trust in partner or jealousy. Social media can affect our relationships as an active user and high usage can lead into a person into engaging in inappropriate activities. These negative outcomes included cheating, separation, and divorce. (Clayton, Nagurney, Smith, 2013) Facebook usage has also been affecting many people's own behaviors and emotions as well as their partner's. The amount of time a person spends on Facebook can be causing behavioral issues like intrusion and distraction. In Elphinston and Noller's (2011) study, they \"speculate that individuals who are seriously affected by Facebook intrusion may also experience jealousy in their current romantic relationship because of the propensity of Facebook to disrupt their personal lives and interpersonal relationships\" (3) It can be essential for studies such as this one to measure the amount of time spent online and the satisfaction level of the relationship. The habit of getting on the Facebook page and scrolling pass hundreds of post can become addictive and intrusive to the relationship due to the lack of attention given in person contrary to the attention spent online (Elphinston Noller 2011) This study will be able to examine if Facebook usage is affecting college students' romantic relationships today. Issues in the Facebook's effect on relationships and self esteem Ortiz 5 relationship can result into jealousy or feelings of neglectfulness, which then can lead into lowering self esteem. Self esteem and Facebook has been repeatedly measured in many research studies. (e.g. Kim, LaRose Peng 2011; de Vries Kuhne, 2015; Anderson, Fagan, Woodnutt and ChamorrPremuzic's 2012) There are various ways to affect someone without having to touch or hear their voice. Someone can simply write a comment that can positively or negatively affect another person's self esteem. (de Vries Kuhne, 2015) In de Vries and Kuhne's (2015) study, they measured how Facebook can be detrimental to a person's well being. In addition, Anderson, Fagan, Woodnutt and Chamorr Premuzic's (2012) study indicates that issues with self esteem might create a barrier between authentic relationships with a significant other and maintaining good mental health. Because of the power Facebook has on a person's self esteem, can that be providing us an effective way to express our emotions to one another? This study further indicates Facebook affects self esteem because of the person's emotional response from disclosing online. The lower self esteem levels are from those who disclose online in order to get acceptance from others and popularity. (Anderson, Fagan, Woodnutt Chamorr Premuzic, 2012) Also, if someone has low self esteem and sees a post where another person appears to be happy or doing something enjoyable, it can make them question their own lifestyles and develop an emotion of envy. In Raymer's (2015) study, along with those emotions, \"more exposure on Facebook leads to lower body image satisfaction and a greater drive for thinness\" (2) These results can decrease a person's self confidence and higher expectations to look a certain way can be a factor towards that low score of self esteem. Moreover, in previous studies, one could hypothesize that high Facebook usage can lead to low satisfaction levels on romantic relationships and self esteem. There has been many Facebook's effect on relationships and self esteem Ortiz 6 research and supported theories that reveal how Facebook related issues and usage can be impactful on our romantic relationships. (Elphinston Noller 2011) Research on self esteem exposes negative emotions outcomes that can come from Facebook usage. (Clayton, Nagurney, Smith, 2013) Considering that, there are consequences for excessively using Facebook on relationships and self esteem, research on these two topics would be valuable.", "corpus_id": 222107483, "venue": "", "year": 2020, "author_names": [ "Janeyshka Ortiz", "" ], "n_citations": 0, "n_key_citations": 0, "score": 0 } ]

While edge computing has advantages in the latency due to the short distance to end users, a variety of business applications have exploded, which has placed higher demands on the basic functions and service performance of the edge servers. This book will analyze these two trends in detail. This chapter introduces the research background, content summary, key contributions, and arrangements of the remaining chapters. 1.1 Research Background The rapid growth of service chains is changing the landscape of cloud based applications. Different stand alone components are now handled by cloud servers, providing cost efficient and reliable services to Internet users. It is known that the workloads from service chains are more complex than the traditional noninteractive (or batch) workloads: for non interactive workloads, such as scientific computing and image processing, they can be processed on one specific server and do not need interactions from other servers. Being not strictly time sensitive, they can be scheduled to run anytime as long as the work could finish before a soft deadline. But for the interactive workloads from service chains, they should go through multiple stand alone components to apply corresponding functions, and this unavoidably introduces additional latency. Meanwhile these interactive chained services typically process real time user requests, such as business transactional and complex gaming control. Therefore, the performance for service chains is in urgent need to be ensured. Nowadays, data centers have become the cornerstones of modern computing infrastructure and one dominating paradigm in the externalization of IT resources. The data center tasks always consist of rich and complex flows which traverse different parts of the network at potentially different times. To minimize the network contention among different tasks, task serialization was widely suggested. This (c) Springer Nature Singapore Pte Ltd. 2020 Y. Zhang, K.

With the adventure of the Internet of Things, more and more visual sensors are connected to the network, which makes the emotion analysis available through the recognition of images. It is necessary to response quickly when negative emotions of children are recognized, which means the processing of images containing negative emotions is delay sensitive. The processing of an enormous amount of images brings challenge for emotion recognition based on traditional cloud computing. Cloud computing is of high scalability and sufficient capability, but cannot meet the need of real time detection due to the time delay of transmission and computing of large amounts of images. Emerging edge computing can help to solve the problem by offloading computing from cloud center to edge nodes. However, because the resource of edge nodes is limited, only part of the computing can be placed at the edge nodes. In our work, an emotion recognition system combined with edge computing and cloud computing is proposed to apply in the kindergarten. Due to delay sensitive negative emotions in this case, a priority scheduling algorithm is also proposed to improve the computing effectiveness of the edge. In this way, the low latency of the edge and the high scalability of the cloud are utilized to reduce the time delay and improve the capacity of the emotion recognition system.

In contrast to prior work focusing only on the placement of applications, this paper addresses the problem of jointly placing IoT applications and the pub/sub brokers on a set of network nodes, considering an application provider who aims at minimizing total end to end delays of all its subscribers. More specifically, we devise two heuristics for joint deployment of brokers and applications and analyze their performance in comparison to the current cloud based IoT solutions wherein both the IoT applications and the brokers are located solely in the cloud. As an application provider should consider not only the location of the application users but also how they are distributed across different network components, we use von Mises distributions to model the degree of clustering of the users of an IoT application. Our simulations show that superior performance of our heuristics in comparison to cloud based IoT operation is most pronounced under a high degree of clustering.

Perhaps more frequent use of EOFs in recent studies is in conjunction with the development of the signal detection and estimation methods of the background uctuations of a detection variable serve as an orthogonal basis set and are used to design optimal techniques for detecting and estimating signals. A detection and prediction approach is to design a lter or optimal weights for the signal to be detected. It has been reported that weighted averaging of data over the surface of the Earth improved the detectability of climatic changes (Hasselmann 1979; Stefanick 1981; Bell 1982) Since the signal to noise ratio (SNR) varies geographically, there exists an optimal geographical weighting of the signal which maximizes the SNR. The design of an optimal weighting function may require detailed knowledge on the natural uctuation of the climate system. A conceptually similar approach is to employ a particular pattern (or patterns) of climatic change for detection and prediction (e.g. Barnett and Hasselmann 1979; Hasselmann 1979) The patterns of interest (also called the predictors) may include the principal components (empirical orthogonal functions) (e. von Storch 1990) among others. This approach also requires complete knowledge of the natural variability of the climate system. To test and improve the detection and prediction techniques addressed above, a complete cross spectral covariance matrix, or similarly, a complete set of the principal components of natural uctuations of the climate system for each frequency band of the spectrum is necessary. In reality, a reliable spectrum of observational covariance matrix is not available because observations are not suuciently long and sampling errors contaminate the observational records (Preisendorfer and Barnett 1977; North et al. 1982) Further, inadequate spatial coverage of observations may introduce bias. Therefore, the covariance matrix of the noise response is often estimated from a simple stochastic model. Kim and North (1991, 1992) examined the covariance matrix in terms of various second moment statistics earlier.

Specifically, arbitrarily small perturbations in a model may cause a change in the dimensions of the associated subspaces. This situation is manifested in computational difficulties which arise in attempts to apply textbook algorithms for computing a minimal realization. Structural instability associated with geometric theories is not unique to control; it arises in the theory of linear equations as well. In this setting, the computational problems have been studied for decades and excellent tools have been developed for coping with the situation. One of the main goals of this paper is to call attention to principal component analysis (Hotelling, 1933) and an algorithm (Golub and Reinsch, 1970) for computing the singular value decompositon of a matrix. Together they form a powerful tool for coping with structural instability in dynamic systems. As developed in this paper, principal component analysis is a technique for analyzing signals. (Singular value decomposition provides the computational machinery. For this reason, Kalman's minimal realization theory is recast in terms of responses to injected signals.

Essentially, we convert tunnel axis extraction into an iterative fitting optimization problem.

First, a calculation method for a closed critical rock body is proposed. Second, block theory and point cloud technology are combined.

However, few studies distinguish among workdays, inherently assuming that the employee experience is uniform across the workweek. In the current study, we examined the trajectories of employees' experiences of job satisfaction and job stressors across the workweek. We proposed two competing theoretical perspectives that result in opposite predictions as to whether job dissatisfaction and perceived job stressors will be higher \"Monday blues\" or lower \"rested and recharged\" at the beginning of the workweek rather than later in the week. Employing a daily diary design with 139 employees (681 matched daily observations) working the traditional workweek, we found that employees reported experiencing lower levels of job satisfaction and perceived more job stressors (i.e. incivility and organizational constraints) at the beginning of the workweek as opposed to later in the week. Additionally, the relationship between perceived incivility and job satisfaction was stronger at the beginning of the workweek.

The reason for this premature distress and deterioration points towards corrosion of steel reinforcement bars used in these structures due to weakening of concrete. The enormous number of structures that needs immediate repair and renovation opens up a huge potential for research in this area. The repair work done in a conventional way using normal cement composite did not work. Whereas repair work done with scientific approach using high and technically competent materials (like epoxies) leads to uneconomical solutions and not durable to withstand our tropical climatic conditions. India being a flourished nation with infinite resources giving us a numerous number of bio polymers that were used in ancient times in ancient construction, if these bio polymers are identified experimentally for their benefits it would give way to eco friendly economical and long lasting structures. The use of corrosion inhibitor is one of the most widely used countermeasures, because of their simplicity in applications and is relatively less expensive. The natural bio polymers are organic materials available from selected plants, seeds, fruit extracts. Plant extracts corrosion inhibitors are cheap, non toxic and environmental friendly. Organic inhibitors offer protection by adsorbing and forming a protective film on the steel surface. Turmeric, Neem extracts in concrete as corrosion inhibitor in different ratio and as a combination are to be studied at depth, as they are commonly available and there is no constraint in getting these resources throughout the year.

Subject headings: Composite structures, steel structure framed structure, seismic design, ETABS v18 1.INTRODUCTION In the past for the construction, the choice was normally between a concrete structure and a masonary structure. Failure of many masonary buildings and multistoried RCC buildings due to earthquake have necessitate structural engineers to look for the different method of construction. Due to significant potential in improving the overall performance through rather modest changes in construction technology, use of composite frame structure is of particular intrest. There is great potential for increasing the volume of steel in construction. Especially the current development need in India. Use of steel, reinforced concrete, and composite steel concrete members which are functioning together such composite systems make use of each type of member in most efficient manner to maximize the structural and economical benefit. 2. ELEMENTS OF COMPOSITE STRUCTURE 2.1 Shear connector Mechanical shear connectors are required at the steelconcrete interface. These connectors are designed to (a) transmit longitudinal shear along the interface and (b) prevent separation of steel beam and concrete slab at the interface. There are three types of shear connectors as, (a) Rigid type (b) Bond or anchorage type (c) Flexible type 2.2 composite deck slab Composite deck slab consist of composite column(encased hot rolled I section) steel beam, steel jacketing. 2.3 composite beam The steel beams are connected to the concrete slab in such a way that the two act as one unit, the beam is called as composite beam. Composite beams are similar to concrete Tbeams where the flange of the T beam is made of concrete slab and the web of the T beam is made of the steel section. 2.4 Composite column It is a compression member consisting either concrete encased hot rolled steel section embedded in concrete. At present there is no Indian standard code covering the design of composite column. The design method largely follows Euro code 4, which provides latest research on composite construction. IS 11384 1985 does not make any specific provisions to composite columns. 3. METHODOLOGY RCC and steel concrete frame models are analyzed. Seismic analysis of both RCC frame structure and composite frame structure are carried out using software tool ETAB v18. Different parameters such as shear force, storey stiffness, storey displacement, storey drift are discussed 3.1 Structural details A typical plan of building is selected for comparative study of RCC and RC steel composite having plan dimensions 25m x 16m as shown in figure. 3 D model is being prepared for the frame analysis of building in ETABS.

Models simulating two different conditions: namely soil structure interaction, and fixed base behavior are considered. The influence of the soil structure interaction in the dynamic behavior of the structure is reflected in an increase in the vibration period as well as increase in the system damping in comparison with the fixed base model, which does not consider the supporting soil. Conventional fixed base analysis ignoring the effect of soil flexibility carried out for the seismic design of buildings may result in unsafe design. Therefore, the effect of SSI is an important issue from the viewpoint of design considerations. Thus to evaluate the realistic behavior of structure the soil structure interaction (SSI) effect shall be incorporated in the analysis. In seismic analysis provision of bracing system is one of the important option for the structure to have sufficient strength with adequate stiffness to resist lateral forces. The different configuration of these bracing systems alters the response of buildings, and therefore, it is important to evaluate the most effective type and location of the bracing systems in view point of stability against SSI effect. In present study, two RC building frames, G+10 and G+15 with six different combinations of steel bracing system at alternate locations incorporating the effect of soil flexibility is considered in order to investigate the effectiveness of bracing system to control SSI.

A CFT column consists of a steel tube and inner filled concrete, where the steel tube is used as a form and confinement of the concrete, with the concrete being the core that prevents buckling of the tube. Due to the development of concrete technology, high performance concrete (HPC) is increasingly used as the internal material of CFT. However, CFT columns are susceptible to local buckling and constant confining stress after yielding of the steel tube. This is why concrete filled carbon fiber reinforced polymer steel composite tubes (CFCT) have been considered. The key parameter, which determines load carrying capacity, and axial and transverse deformation is the number of CFRP layers. The test results showed that local buckling of the steel tube can be effectively eliminated and that the compressive strength of CFCT is enhanced by the external confinement. It has been shown that the stress strain characteristic depends on confinement pressure.

So for new construction of high rise building and apartments, steel concrete composite can be used to replace the traditional RCC section because of their excellent strength, ductility, better economy, better energy absorption capacity and performance during earthquake.

[ { "doc_id": "201640412", "title": "Deaf Characters in Young Adult Literature", "abstract": "The multicultural literature movement has its roots in civil rights and the desire to give voice and representation to marginalized cultures. Literature is a societal artifact that can inform and influence the development of cultural identity. Deaf culture is a unique culture that is underrepresented in young adult literature. This underrepresentation places more importance on accurate representations of Deaf culture since young adult fiction may be the only exposure to Deaf culture that both hearing and deaf teenagers may have. Accurate representation in literature is necessary for deaf to see themselves in what they read and for hearing to better understand this unique culture. This study analyzed 20 young adult novels published between 2000 and 2017. Each novel featured a deaf or hard of hearing teenager. A phenomenography approach with a qualitative content analysis method was utilized to inform a better understanding of the representation of deaf characters and Deaf culture within current young adult literature. Models of disability as established by Clogston (1990, 1991, 1993) and Haller (1995) were used to focus the coding analysis. Two research questions were addressed. What model of disability do these books represent? What aspects of Deaf culture, communication issues, and societal issues are represented in young adult fiction? Results of the study determined the most prevalent model of disability represented was the traditional medical model. The coding also revealed themes surrounding Deaf culture, the issues in communication that deaf face, and societal issues surrounding the deaf. Stories have power. From the oral tradition of telling stories, through today's modern methods of storytelling, stories have passed on knowledge from generation to generation. Stories can document the history of a culture and can shape and impact an individual's cultural identity and understanding of self. Since adolescence is a time of discovery when young adults learn more about the world and their place in it, young adult literature can impact the cultural identity development of adolescents. Reading about cultures and characters can help adolescents form connections to and understandings of not only their cultural identity, but also that of others (Koss, 2015, Louie, 2005) The power of literature means that how a culture is portrayed in literature impacts how young adults learn about not only themselves, but society as well. Because of the impact literary representations have on cultural identity, the representation of cultures needs to be authentic. Therefore, it is important to understand stereotypes in literature and how they impact the view of a culture; otherwise these representations can reinforce negative stereotypes and lead to misunderstandings concerning the culture (Gopalakrishnan, 2011, pg. 214) Without accurate representation of a culture in literature, a method of learning about cultures in an authentic way is lost. It is also important that authentic cultural representation be easily accessible and available. The social power of cultural groups is also represented in literature and those who lack cultural power tend to be excluded from literature and other important forms of cultural representation (Taxel, 1994) The publication and selection of books assigns value to the book and its contents. If the literature is not published or cannot be found, then the opportunity for learning about the culture and its inherent value is missed. Deaf culture is found in few modern, young adult literary works. This makes access to Deaf culture in literature limited and makes it even more important that the representation of Deaf culture in those young adult books be authentic. Because of the impact of literature on the development of cultural identity, it is important to know if Deaf culture is not only represented in young adult literature, but represented accurately. The purpose of this study was to investigate how deaf characters were represented in young adult fiction published between 2000 and 2017. The study applied a phenomenography approach with a qualitative content analysis method to inform a better understanding of the representation of deaf characters and Deaf culture within current young adult literature. 1 Gangwish: Deaf in Young Adult Literature Published by DigitalCommons@UNO, 2019 What Defines Deaf Culture? Deaf culture is not defined by a region or a shared ethnic background, but rather by a language and shared experience. Deaf culture is comprised of many variables and its members may encounter various obstacles and frustrations because of misunderstanding or lack of knowledge by those outside of Deaf culture (Padden Humphries, 2005) While many people may believe Deaf culture is defined by a lack of hearing, it is not. Rather it is defined by a focus on the beliefs and practices among deaf and the visual nature of their language. Padden Humphries (2005) stated: As a community made up of some individuals who do not speak and some who do, some who do not hear at all and some who hear some, and all of whom draw the label of \"disabled\" by the larger community, Deaf people are seen as clearly not like anyone else. We often feel besieged, controlled, and patronized, even as our remarkable sign language is celebrated and admired in public (p. 7) Those who associate with Deaf culture may be deaf, hard of hearing, or hearing. They may have grown up in deaf or hearing households. They may have attended deaf or hearing schools. The culture is defined by a personal decision to become a part of the culture because of the shared values and beliefs. This study will utilize the common convention of the capitalized word, Deaf, in reference to the cultural group and its practices, and the lowercase word, deaf, in reference to the medical condition of hearing loss. For the purposes of this study, Deaf culture is defined by a focus on beliefs and practices among the Deaf, especially the primary role that sign language plays in their community (Padden Humphries, 2005) It is because of the many variances within Deaf culture, that learning about it and becoming a part of it may be difficult. For instance, a deaf person who grows up in a hearing household and attends a hearing school may not have the opportunity to learn about Deaf culture. In many cases, Deaf culture is learned through interaction with the Deaf. If that interaction is not available, a deaf person may not have the opportunity to learn about a culture that could have great impact on their life. Mainstream society may view hearing loss as a disability, but Deaf culture rejects this concept and instead self identifies as a unique cultural group brought about by the visual nature of their language (Bailes, 2002) Willard (1998) addressed the perception of disability as portrayed in the media. He stated: If anyone has anything to overcome, I would say it's the people in the media. They are the ones who keep feeding the misconception that people with disabilities are not happy or whole until they have overcome their disability. Instead, why not recognize that a disability is often a part of our lives, something that makes us who we are? Our ears may not work as well as we'd like, but we have nothing to be ashamed of and certainly nothing that needs to be overcome (p. 274) In the United States, American Sign Language (ASL) is the primary language of the Deaf. This language is very visual in nature and is one of the core components of Deaf culture. Ariella Dramin, a current student at Gallaudet remarks, \"We're a community, we're fine. We have a language\" (Shah, 2017) The unique nature of ASL makes it a pathway towards bringing Deaf culture together and has become an avenue of pride for the community. Although many deaf individuals can read lips and voice, Deaf culture acknowledges that ASL is their language. It is important to remember that being born deaf does not make a person automatically a member of Deaf culture. Since Lane, Hoffmeister and Bahan (1996) found that \"Nine out of ten deaf people come from hearing homes where deaf language and culture are rarely to be found,\" many deaf may not have the opportunity to interact with and learn about the larger Deaf culture. This can lead to a struggle during adolescence in the development of cultural identity with Deaf because many deaf children in these circumstances will not learn about Deaf cultural heritage from their hearing parents (Lane, Hoffmeister Bahan, 1996, p. 160) Lane, Hoffmeister and Bahan (1996) discussed the impact of having culturally different parents on deaf children. This situation can lead to a loss of connection with their Deaf identity. It can delay the acquisition of ASL. In many cases, deaf children born to hearing parents are faced with cochlear implants and speech drills in order to make them more acceptable in hearing society. But these choices can lead to lack of acceptance by Deaf culture. An anomaly exists in these situations though, because deaf children may seek out Deaf culture in order to identify with their language, find role models, and develop an understanding of the unique Deaf culture. 2 Journal of Curriculum, Teaching, Learning and Leadership in Education, Vol. 4, Iss. 1 [2019] Art. 1 https:/digitalcommons.unomaha.edu/ctlle/vol4/iss1/1 Media and Cultural Identity Media, and for the focus of this study, literature in particular, as a societal artifact can impact not only view of self, but also influence how a culture is viewed by those outside of that culture. Fiction is a way of reflecting reality and can represent the concerns of that culture as well as how those concerns are addressed. It is a type of cultural artifact that reflects the perceptions and attitudes of society at the time, and as such it can inform and shape understanding about the values of a specific culture (Fairclough, 1989; Guella, 1983; Harris Baskin, 1987; Taxel, 1994) Accordin", "corpus_id": 201640412, "venue": "", "year": 2019, "author_names": [ "Kim Gangwish" ], "n_citations": 0, "n_key_citations": 0, "score": 1 }, { "doc_id": "148799212", "title": "Disabling Characters: Representations of Disability in Young Adult Literature", "abstract": "Disabling Characters: Representations of Disability in Young Adult Literature Patricia A.

George, and J.L. Schatz, is the follow up collection to an earlier anthology edited by Nocella II, Judy Bentley and Janet Duncan. Published in 2012, Earth, Animal, and Disability Liberation: The Rise of the Eco Ability Movement was visionary in illuminating entanglements of the struggles that people with disabilities share with environmental and nonhuman animal oppression (similar to the realization of the shared oppression of women, animals and the environment that sparked ecofeminism) This connection is termed 'eco ability. Major themes from Earth, Animal, and Disability Liberation were that those not considered normal either physically, mentally, or emotionally are not disabled but merely differently abled, and that the underlying presumption of normalcy is itself a flawed social construction, not a well defined criterion for judging one's suitability for inclusion into moral and social consideration. Intersectionality proceeds through seven chapters that build on these foundational themes while making new connections. Contributors have backgrounds in special education or disability studies, and/or environmental science or education. Thus the expertise in this volume is admirable. With case studies and experiences from the U.S. and Canada, on the whole, Intersectionality focuses on inclusion of the disabled person into activism and liberation discourse, FROM DISABILITY TO ECO ABILITY 331 and not marginalizing individuals deemed 'others' or outside the norm, within social justice struggles. As a case in point, in her contribution, Judy K.C. Bentley describes going to a conference on disability studies as someone studying special education and feeling marginalized by other attendees. Disability studies scholars overgeneralized special education teachers as oppressive and an overall hindrance to students with disabilities and disability liberation because teachers uncritically followed unhelpful school and federal mandates. This constructed a scholarteacher dichotomous hierarchy, and came from those whom Bentley viewed as allies in proclaiming inclusion and speaking against 'Othering. Sarah Conrad addresses this theme further by stressing the point that the focus on in person, physically related activism as the hallmark of environmental and animal advocates marginalizes people with disabilities who may wish to participate but whose physical, emotional, and/or mental stresses impede the possibility. Other themes include: emphasising that Western education reinforces dualisms that value one category at the expense of another (such as able versus disabled, human versus animal) we must learn to be interdependent, not independent (value our diversity) not to work for those with needs, but work with everyone in community building; and that if we do not rethink and re practice the anthropocentric and ableist outlook, we will reconstruct the same oppressive web of circumstances we are in now. What is of invaluable importance about Intersectionality is that it alerts readers to the possibility that while we may proclaim inclusion, at the same time we may perpetuate potentially prejudicial oversights that exclude certain groups. Although a focused volume, Intersectionality does not limit itself to the intersections of animal, disability or environmental activism and liberation. It also encourages reflection on what other implicit biases might exist within individuals or organizations. Sarah Conrad gives examples of how racist, sexist, and ableist notions can contribute to a lack of professional care for those who need it. Only when such injustices are realized and exposed can we then take steps to begin to remedy them. Intersectionality powerfully argues that society generally views disabled people as holding back progress. The authors maintain that what needs to change is to instead view society as holding back the differently abled, and that this is what actually precludes progress. Disability is FROM DISABILITY TO ECO ABILITY 332 not a flaw in the individual that needs to be 'cured. However, the struggles faced by those with disabilities reflect an institutional flaw in mainstream Western culture and society that does need to be addressed. Disability liberation is not helping a person to 'overcome' their disability, but involves working with the disabled to include them in a holistic community and resist the tendency of society to enforce oppressive norms of ability, beauty, and health. We are continually reminded about the role capitalism plays in this with its focus on appealing to such norms to sell commodities through its construction of the 'desirable. In the first essay, by Scott Hurley, on 'the dog fancy' which is the promotion, breeding, and showing of dogs, the connection between capitalism, disability and nonhuman animals is drawn. Dogbreeding for competition is done to enhance and continue the breed, which has resulted in physical disabilities in many individual animals. Each breed has its own standard set by the American Kennel Club (AKC) These imposed ideals are often more akin to deformities and can create significant levels of discomfort and pain such as breathing problems or hip and back pain. If genetics do not cooperate with human desires, two outcomes arise. One is that surgical measures may be used to enhance a dog's look; another is that a dog may be deemed unsuitable for competition, in which case they are considered useless and somehow dispensed with. Dogs that fall outside the norms set by the AKC are considered disabled because they are not desirable for breeding, which recalls the human eugenics movement. Similar results are found in other animal breeding competitions. For instance, pigeon breeding creates body types that would have difficulty performing many essential life functions such as walking or flying in order to win awards (see the photo stream, Australian National Pigeon Association, n.d. Outside of prize competitions, these birds' bodies would be considered grotesquely deformed by most. Sarah Roberts Cady examines two ways in which animal, environmental, and disability studies intersect: reason and normalcy. Reason is the vastly favored quality in granting moral considerations to either living or nonliving beings. Normalcy is a social construction that upholds the status quo which is hurtful to those with disabilities. Roberts Cady argues that on the basis of having an impaired reasoning ability, society excludes people with disabilities from being able to participate which thereby creates the erroneous idea that people with disabilities cannot participate. This reinforces the stigmatized image of the disabled as a hindrance. Such FROM DISABILITY TO ECO ABILITY 333 discrimination has become so normalized that it is rendered invisible: most of us simply do not look at a set of stairs as a quiet but profound act of discrimination towards those in wheelchairs. While both The Intersectionality of Critical Animal, Disability, and Environmental Studies as well as its predecessor Earth, Animal, and Disability Liberation are explicitly intersectional in scope, they tend to focus slightly more on the (human) disability and environmental aspects. Animals are far from ignored, however. In addition to examples mentioned above, Bentley draws parallels between animals in factory farms and the elderly in nursing homes, based on both institutions being profit driven at the expense of the welfare of their occupants, and Amber E. George examines messages of queerness, speciesism, and disability in Looney Toons characters. George gives many examples of episodes where cartoons depict animals, the disabled, and nonheterosexuals as sources for entertainment. The reality of this portrayal creates and helps perpetuate the marginalization and violence towards these vulnerable groups. Altogether, Intersectionality provides a much needed voice that links humans, nonhuman animals, and the environment.

Bobet", "abstract": "Bobet, Leah. Above New York: Arthur A. Levine Books Scholastic, 2012. Print This Young Adult urban fantasy novel takes place in present day Toronto, Canada. The main character is Matthew, a teenager growing up in an underground, secret community known as Safe. This community was founded by Matthew's guardian, Atticus, for disabled outcasts and people with abnormalities. For example, Atticus has claws for hands, and Matthew has scales. In this underground community, Matthew is Teller, which means that he collects and remembers the stories of different individuals living in Safe. Matthew is in love with the traumatized girl Ariel, who can shape shift into a bee and has wings. Ariel came to the Safe as a teenager, and lived in the city before then, but she is slow to trust others, including Matthew, and runs away frequently. Safe is threatened by an exile, known as Corner, who works with an army of shadows. Eventually, Corner invades Safe by following Ariel home after one of the times she ran away. This causes the community to disperse Above, which is actually downtown Toronto. Once there, with the help of Ariel, Matthew has to reunite his community, and reclaim Safe. In order to do this, Matthew must discover the history of Corner, and its connection to Safe. He learns that there are two sides to every story, and not everything is black and white. Good people can make mistakes, and love and relationships are complex and defining elements of what it means to be human. Above has important messages about themes of \"good\" and \"evil\" and the gray areas in between. By blurring the lines between fantasy, magic, and medicine, these themes are easy to bridge into the real world. The focus on outcasts and disabled people gives the book a unique perspective, and the setting takes readers to both well known and often passed over areas of downtown Toronto. The book suffers from poor setup, however, and slow character development. Leah Bobet uses a stilted writing style, meant to reflect the main character's education and state of mind. Often this style makes the plotline difficult to follow, and undercuts some of the more intriguing descriptions of Toronto. Readers are also launched into the world without explanation, which can make it difficult to figure out what is going on for the first half of the book. The story can be even more confusing as it is told in patchworks. Outside of Matthew's main storyline, the narratives of other characters are interwoven into the book, so not all events are chronological. Above has a good premise that will appeal to the right group of young adults, but with the difficult writing level and the lack of setup, some of the target audience might lose interest before finishing the novel. It is worth nothing that some of the content deals with difficult topics, including mental illness, abuse, disability, poverty, gender identification, people of different and mixed ethnicities, experimentation on people, and death.

In this well written book by Professor Bruneau, the theme is illustrated by fictional characters who are accompanied by scenes of an earthquake disaster and the surreal level of incompetence and pettiness with which they respond to it. Most earthquake engineers write their books with dry, third person diction. Bruneau wrote this book with a combination of blunt first person language spoken by the novel's characters and well crafted narrative sentences that include such picturesque metaphors as \"violent trespasser\" (the earthquake that suddenly enters your house and trashes it) or the way a warehouse littered with debris looks like \"the bedroom of some giant teenager.\" He portrays the perception of a person undergoing the earthquake in a way that you will recognize as quite accurate, if you have ever undergone one: \"seconds and inches became minutes and feet.\" The magnitude 7 earthquake that sets the plot in motion hits Montreal with bull's eye accuracy right under the city, disabling all the bridges across the rivers that surround and divide it. Over 3.5 million people live in that urban region. Without giving away any of the plot, we can say that by the end of the book, the population is reduced by over 1,000 a plausible loss estimate for this scenario and one that certainly isn't sensationalist.

In the ensuing four years, I studied a number of articles concerning different subjects in biology and was struck by the key vocabulary that was used for the description of the essential activities of cellular life, such as \"genetic code,\" \"genetic information,\" \"cell cell communication,\" \"nucleotide sequences,\" \"protein coding sequences,\" \"self/nonself recognition\" all of which connote themes of communication and exchange of information, similar to the themes I had encountered in my studies of philosophy and action theory. Of particular influence on my thinking were the articles and books of Karl von Frisch, who received the Nobel Prize for his work on the language of bees; and a book by Manfred Eigen, in which he developed a profound argument for the idea that the genetic code functions not only as an analogue of natural human language but that both the evolution of life and the evolution of the mind crucially depend on the characteristic features of languages. According to these and many other results of the discourse in the philosophy of science in the 20th century (especially between 1920 and 1980) it was clear that if the genetic code functions like a natural language then a variety of consequences follow because several preconditions must have been met. First, considering the genetic code as a natural language requires there to be a repertoire of signs (indices, icons, symbols)a that can be combinatorially arranged according to syntactic rules, similar to words composed of the characters of the alphabet, to generate information. Without syntactic rules to determine correct sequence order, the combination of signs could not carry informational content, that is, meaning (similarly, if our natural language had no syntactic rules, meaning could not be ascribed to randomly generated collections of words) In other words, a coherent syntax excludes randomly derived mixtures of characters of an alphabet; and for humans, coherent syntax is generated by humans who are competent with the syntactic rules. This book, for example, could contain the same characters but in a random order; such a book would be meaningless. Without competent authors who combine the characters according to a set of coherent syntactic and semantic rules, meaning does not exist.

The author touches upon a variety of issues emerging from the practice of its organization: the difficulties, sometimes reluctance of HR managers to confront racism, their quest for tools, the blockings around equality data collection, the ambivalent role of trade unions as well as post modern tensions between standardization and individualization which lie at the heart of diversity management.", "corpus_id": 201323168, "venue": "International Perspectives on Equality, Diversity and Inclusion", "year": 2019, "author_names": [ "Michael Privot" ], "n_citations": 0, "n_key_citations": 0, "score": 1 }, { "doc_id": "158266897", "title": "Race Discrimination at Work: The Moderating Role of Trade Unionism in English Local Government", "abstract": "Workplace racism remains a serious issue despite over forty years of legislation alongside a raft of HRM policies.

To achieve the objective of this paper is to examine the socio economic determinants of urban youth unemployment logistic model was used. A simple random sampling technique employed to select 395 youth were used. Both quantitative and qualitative data were collected from sampled youth unemployed persons through questionnaire and interview. Both descriptive and econometric data analyses techniques were applied. From the econometrics result revealed that confidence ,education status access to information human related factor, institutional factors ,socioeconomic and demographic factors were significantly affect the youth unemployment status in the study area The result also indicates that the higher months spent on searching, the higher the probability of getting job. This shows the cost of job search is positively related with employment status of the youth, as cost of search increases the higher the probability of being employed. The result also indicates that educational level of the youth's household head has a negative and statistically significant effect on employment status of the youth at 10 percent level of significance. This finding is inconsistent with the general fact and the hypotheses of this study. Since confidence level of the youth matters for employment status of the youth, the concerned bodies should develop the confidence level of the youth by providing different trainings for the youth. The concerned body, especially the government should provide facilities related with information access like mass media and magazines in the study area.

All parts of the UK will be differently affected by the decision to leave the European Union (EU) (i.e. Brexit) after 29 March 2019, particularly by the creation of an independent trade policy. As a member of the EU customs union and of the single market, the UK does not at present have an independent trade policy. Instead, trade policy is \"largely determined by the EU\"2, a position that will change upon the UK's departure from the EU. While trade is a reserved matter, areas of devolved competence such as agriculture will need to be taken account of in any future UK trade policy. The devolved administrations will require to be involved in what Dr Fox identified as \"a once in a lifetime opportunity to build a stronger, fairer and more prosperous United Kingdom that is more open and outward looking than ever before.\"3 Indeed, the Policy Paper mentioned above further recognised that, \"(t)he devolved administrations will have a direct interest in our future trade agreements,\"4 with this recognition accompanied by a commitment, \"to seek the input of the devolved administrations to ensure they influence the UK's future trade policy, recognising the role they will have in developing and delivering it.\"5 In this present paper, we critically review the UK government's current approach to involving the devolved administrations in post Brexit trade policy development. We demonstrate that there is a significant lack of clarity on the future role of the devolved administrations in the development of trade policy. The Scottish government is particularly concerned in this respect given that its extensive devolution settlement includes areas with significant trade dimensions such as agriculture, fisheries and environmental policy.

The question many are asking is, have county governments initiated strategies in place to improve food security and ultimately contribute to the economy. Agriculture is the major contributor of our economy today. Kenya needs to be a self sufficient country and feed its people. County governments have a huge role in ensuring this objective achieved. Based on this, a research title is proposed \"Understanding the influence and effects of devolution on agricultural development: A case study of Garissa county, Kenya\" The research seeks to clarify to the public and the other stakeholders concerned if actually devolved units have done anything to improve the agricultural sector since its inception.

At a glance, devolution has come with both benefits and downsides, which are unique to the service/function that has been devolved. Agriculture was previously a function of the National government, under the Ministry of Agriculture. It is currently a devolved ministry, no longer under the sole control of the National government. Same as other devolved functions, it was expected that devolving the ministry of Agriculture would lead to better agricultural production at county level. Devolution Agricultural functions was expected to enhance agricultural production in the counties. The study thus sought to establish the effect of devolution of the agricultural sector on the livelihoods in Wajir County. This study was guided by the following objectives; to establish the effects of devolution of agricultural sector on the empowerment of small scale farmers, to determine the effects of devolution of agricultural sector on incomes of households and to examine the effects of devolution of agricultural sector on food security of households in Wajir County. The study is hinged on the Sustainable Livelihood Approach. The study adopted a descriptive survey that helped in determining and reports the way things are and attempts to describe such things as possible behavior, attitudes, values, and characteristics. The study targeted5273 small scale farmers and agricultural officers across all Wajir sub counties. The study sampled 372 farmers from all the Sub Counties in Wajir. Therefore, 372 farmers and 6 agricultural officers were used making a total sample size of 378 respondents. The researcher purposively selected six agricultural officers one from each sub county. In identifying the farmers from each sub county, the study used simple random sampling. The study will adopt both qualitative and quantitative data. The study used questionnaires for collecting data from 372 farmers, which will be constructed based on the research objectives. The questionnaires were administered using drop and pick method; this provided farmers with enough time to answer the questions. Quantitative data was analysed using descriptive statistics such as mean, mode, percentages and standard deviation. The study used Chi Square to establish the relationship between the variables. The study findings indicated that the effect of devolution of agricultural activities in Wajir County has significantly affected the level of food security, sources of income and empowerment among the households in the county. Due to devolution of the agricultural activities, the county government now provides extension services, funds, inputs such as fertilizers and credits for agricultural activities and that has led to an increase in food production which has greatly improved food security and enhanced income generation. The small scale farmers no longer rely on livestock farming but also crop farming. Since the study findings present a significant effect of devolution of the agricultural activities to the county level in Wajir, it recommends that the county government should invest more in some of the agricultural activities such as access to agricultural services like Plough and tractor, Borehole and dam for irrigation, Extension services, Livestock vaccination and Disease surveillance, control, and awareness. There should also be an increase in the provision of services such as the provision of farm inputs and marketing of farm products on behalf of farmers in order to encourage more participation in agriculture by the households.

The findings show a number of positive benefits of the transition for DDAs, including more opportunities for employment mobility and the chance to engage more with local citizens in designing agricultural projects. Yet, financial constraints are the main complaint, with low and uncertain funding a common hindrance to delivering services and adequately staffing offices. Budget data reveals that the share of funding budgeted for agriculture has changed only marginally since 2012 while agricultural expenditures in absolute terms and as a proportion of agricultural households has declined, even in comparison to other devolved sectors. Political incentives may be partially responsible for these trends in budgeting as elected Assembly members tend to prioritize other sectors with more visible outcomes.

Among those applications, the automatic classification of biomedical literature stands out as an important application for automatic document classification strategies. Biomedical staff and researchers have to deal with a lot of literature in their daily activities, so it would be useful a system that allows for accessing to documents of interest in a simple and effective way; thus, it is necessary that these documents are sorted based on some criteria that is to say, they have to be classified. Documents to classify are usually represented following the bag of words (BoW) paradigm. Features are words in the text thus suffering from synonymy and polysemy and their weights are just based on their frequency of occurrence. This paper presents an empirical study of the efficiency of a classifier that leverages encyclopedic background knowledge concretely Wikipedia in order to create bag of concepts (BoC) representations of documents, understanding concept as \"unit of meaning\" and thus tackling synonymy and polysemy. Besides, the weighting of concepts is based on their semantic relevance in the text. For the evaluation of the proposal, empirical experiments have been conducted with one of the commonly used corpora for evaluating classification and retrieval of biomedical information, OHSUMED, and also with a purpose built corpus of MEDLINE biomedical abstracts, UVigoMED. Results obtained show that the Wikipedia based bag of concepts representation outperforms the classical bag of words representation up to 157% in the single label classification problem and up to 100% in the multi label problem for OHSUMED corpus, and up to 122% in the single label classification problem and up to 155% in the multi label problem for UVigoMED corpus.", "corpus_id": 17166290, "venue": "PeerJ", "year": 2015, "author_names": [ "Marcos Antonio Mourino Garcia", "Roberto Perez Rodriguez", "Luis Anido Rifon" ], "n_citations": 3, "n_key_citations": 0, "score": 0 }, { "doc_id": "49293359", "title": "A Bag of Concepts Approach for Biomedical Document Classification Using Wikipedia Knowledge* Spanish English Cross language Case Study.", "abstract": "OBJECTIVES The ability to efficiently review the existing literature is essential for the rapid progress of research. This paper describes a classifier of text documents, represented as vectors in spaces of Wikipedia concepts, and analyses its suitability for classification of Spanish biomedical documents when only English documents are available for training. We propose the cross language concept matching (CLCM) technique, which relies on Wikipedia interlanguage links to convert concept vectors from the Spanish to the English space. METHODS The performance of the classifier is compared to several baselines: a classifier based on machine translation, a classifier that represents documents after performing Explicit Semantic Analysis (ESA) and a classifier that uses a domain specific semantic annotator (MetaMap) The corpus used for the experiments (Cross Language UVigoMED) was purpose built for this study, and it is composed of 12,832 English and 2,184 Spanish MEDLINE abstracts. RESULTS The performance of our approach is superior to any other state of the art classifier in the benchmark, with performance increases up to: 124% over classical machine translation, 332% over MetaMap, and 60 times over the classifier based on ESA. The results have statistical significance, showing p values 0.0001.

The WTO presides over a rule based trading system based on norms that are almost universally accepted and respected by its 163 members.

During the last 15 years, most WTO members have massively lowered barriers to trade, investment, and services bilaterally, regionally, and unilaterally indeed, everywhere except through the WTO.

It is stated that the deadlock situation during the negotiations forced the members of the WTO to step back from the batch method of decision making and the principle \"everything is compulsory for all\" This opened the way for the progress in reduction of trade barriers with the help of agreements between limited number of the participants (selective liberalization) and preferential regional trade agreements of the new type \"liberalization for those who care\" A fear is expressed that the current trade conflict between the US and China may lead to the opening of wide scale trade war between the two countries and may give an impetus for the outbreak of similar \"wars\" between other participants in the world trade and, at worst, for the collapse of the multilateral trading system that has been built during the past seventy years.

To provide a thorough understanding of the current status of research on this new phenomenon and stimulate more scholarly interest, we conducted a systematic review of existing spiritual leadership literature. By analyzing 59 empirical studies published in peer reviewed journals, we unraveled how the concept of spiritual leadership was defined, developed, utilized and validated by researchers across disciplines. This article also provides some directions for future research by highlighting knowledge gaps and critical issues identified in previous studies, such as definitions, methodologies, construct measurements, research contexts, and nomological relationships of spiritual leadership. For scholars who are interested in pursuing spiritual leadership research, this review can serve as a useful reference guide.", "corpus_id": 213523455, "venue": "Journal of Management, Spirituality Religion", "year": 2020, "author_names": [ "Jihye Oh", "Jia Wang" ], "n_citations": 9, "n_key_citations": 2, "score": 0 }, { "doc_id": "210480338", "title": "Do organizational citizenship behavior and work satisfaction mediate the relationship between spiritual leadership and employee performance?", "abstract": "Article history: Received: July 4 2019 Received in revised format: September 14 2019 Accepted: October 30, 2019 Available online: October 30, 2019 This study aims to analyze the role of organizational citizenship behavior (OCB) and work satisfaction to mediate the effect of spiritual leadership of employee performance at Bank BRI shariah Malang.

AIM This study examines how and why spiritual leadership may have a positive influence on nurses' subjective well being. METHOD A total of 339 registered nurses from five public hospitals in mainland China participated in this study. Hypotheses were tested using the PROCESS macro developed by Hayes (2017) RESULTS Spiritual leadership influenced subjective well being indirectly through workplace spirituality. The interaction of spiritual leadership and power distance orientation on workplace spirituality was significant. Power distance orientation moderates the indirect effect of spiritual leadership on subjective well being through workplace spirituality and this indirect effect is more positive for nurse with lower power distance orientation. CONCLUSIONS Spiritual leadership is a significant contextual factor in the workplace that may influence the nurses' workplace spirituality and subjective well being. Based on their power distance orientation, nurses may have different responses to spiritual leadership, resulting in differing levels of workplace spirituality.

Much of this research is focused on explicitly explaining decisions or actions to a human observer, and it should not be controversial to say that looking at how humans explain to each other can serve as a useful starting point for explanation in artificial intelligence. However, it is fair to say that most work in explainable artificial intelligence uses only the researchers' intuition of what constitutes a `good' explanation. There exists vast and valuable bodies of research in philosophy, psychology, and cognitive science of how people define, generate, select, evaluate, and present explanations, which argues that people employ certain cognitive biases and social expectations towards the explanation process. This paper argues that the field of explainable artificial intelligence should build on this existing research, and reviews relevant papers from philosophy, cognitive psychology/science, and social psychology, which study these topics. It draws out some important findings, and discusses ways that these can be infused with work on explainable artificial intelligence.", "corpus_id": 36024272, "venue": "Artif.

For this to occur, the entire community stands in front of the barrier of explainability, an inherent problem of AI techniques brought by sub symbolism (e.g. ensembles or Deep Neural Networks) that were not present in the last hype of AI. Paradigms underlying this problem fall within the so called eXplainable AI (XAI) field, which is acknowledged as a crucial feature for the practical deployment of AI models. This overview examines the existing literature in the field of XAI, including a prospect toward what is yet to be reached. We summarize previous efforts to define explainability in Machine Learning, establishing a novel definition that covers prior conceptual propositions with a major focus on the audience for which explainability is sought. We then propose and discuss about a taxonomy of recent contributions related to the explainability of different Machine Learning models, including those aimed at Deep Learning methods for which a second taxonomy is built. This literature analysis serves as the background for a series of challenges faced by XAI, such as the crossroads between data fusion and explainability. Our prospects lead toward the concept of Responsible Artificial Intelligence, namely, a methodology for the large scale implementation of AI methods in real organizations with fairness, model explainability and accountability at its core.

METHODS We developed a modified stacked auto encoder for modeling the transmission dynamics of the epidemics. We applied this model to real time forecasting the confirmed cases of Covid 19 across China. The data were collected from January 11 to February 27, 2020 by WHO. We used the latent variables in the auto encoder and clustering algorithms to group the provinces/cities for investigating the transmission structure. RESULTS We forecasted curves of cumulative confirmed cases of Covid 19 across China from Jan 20, 2020 to April 20, 2020. Using the multiple step forecasting, the estimated average errors of 6 step, 7 step, 8 step, 9 step and 10 step forecasting were 1.64% 2.27% 2.14% 2.08% 0.73% respectively. We predicted that the time points of the provinces/cities entering the plateau of the forecasted transmission dynamic curves varied, ranging from Jan 21 to April 19, 2020.

These weaknesses are caused by the limited exposure millennials in South Africa have to digital devices and Internet connectivity. In spite of these impediments, their future careers in an increasingly globalised world require them to behave like, transact and engage with full fledged digital citizens from the global north. Digital citizenship is the ability to use technology safely, responsibly, critically, productively and civically. This raises intellectual curiosity about the extent to which the African millennial is prepared for a world that expects them to be digital citizens. This article, therefore, investigates the challenges faced by the South African millennial as they navigate an unusual route to digital citizenship. We adopted the activity theory for a mixed methods study that consists of a survey of 148 questionnaires and 15 in depth interviews. The findings show that while university going millennials acquire digital literacy, their development of digital citizenship is affected by lack of mentors and access (i.e. connectivity and devices) at home and lack of soft skills training (i.e. online safety, digital etiquette and inadequate information literacy) at the university.", "corpus_id": 150304205, "venue": "", "year": 2018, "author_names": [ "Sam Takavarasha", "Liezel Cilliers", "Willie Tafadzwa Chinyamurindi" ], "n_citations": 2, "n_key_citations": 0, "score": 0 }, { "doc_id": "199873554", "title": "A study on the digital citizenship level of preservice teachers according to diverse variables", "abstract": "The purpose of this study is to identify and examine the digital citizenship levels of preservice teachers according to diverse variables.

The network takes a face video or face image set of a person with a variable number of face images as its input, and produces a compact, fixed dimension feature representation for recognition. The whole network is composed of two modules. The feature embedding module is a deep Convolutional Neural Network (CNN) which maps each face image to a feature vector. The aggregation module consists of two attention blocks which adaptively aggregate the feature vectors to form a single feature inside the convex hull spanned by them. Due to the attention mechanism, the aggregation is invariant to the image order. Our NAN is trained with a standard classification or verification loss without any extra supervision signal, and we found that it automatically learns to advocate high quality face images while repelling low quality ones such as blurred, occluded and improperly exposed faces.

Compared with previous systems for scene text recognition, the proposed architecture possesses four distinctive properties: (1) It is end to end trainable, in contrast to most of the existing algorithms whose components are separately trained and tuned. (2) It naturally handles sequences in arbitrary lengths, involving no character segmentation or horizontal scale normalization. (3) It is not confined to any predefined lexicon and achieves remarkable performances in both lexicon free and lexicon based scene text recognition tasks.

Regularized iterative algorithms have emerged as the standard approach to ill posed inverse problems in the past few decades. These methods produce excellent results, but can be challenging to deploy in practice due to factors including the high computational cost of the forward and adjoint operators and the difficulty of hyperparameter selection. The starting point of this paper is the observation that unrolled iterative methods have the form of a CNN (filtering followed by pointwise non linearity) when the normal operator <inline formula> <tex math notation=\"LaTeX\"$H^}H$ /tex math>/inline formula> where <inline formula> <tex math notation=\"LaTeX\"$H^ /tex math>/inline formula> is the adjoint of the forward imaging operator, <inline formula> <tex math notation=\"LaTeX\"$H$ /tex math>/inline formula> of the forward model is a convolution. Based on this observation, we propose using direct inversion followed by a CNN to solve normal convolutional inverse problems. The direct inversion encapsulates the physical model of the system, but leads to artifacts when the problem is ill posed; the CNN combines multiresolution decomposition and residual learning in order to learn to remove these artifacts while preserving image structure. We demonstrate the performance of the proposed network in sparse view reconstruction (down to 50 views) on parallel beam X ray computed tomography in synthetic phantoms as well as in real experimental sinograms.

Moreover, recent machine learning based methods also depend on synthetic blur datasets generated under these assumptions. This makes conventional deblurring methods fail to remove blurs where blur kernel is difficult to approximate or parameterize (e.g. object motion boundaries) In this work, we propose a multi scale convolutional neural network that restores sharp images in an end to end manner where blur is caused by various sources.

Mittlerweile stehen zahlreiche Substanzen im Fokus der Forschung, darunter bereits verfugbare Medikamente ebenso wie experimentelle Substanzen, die sich moglicherweise fur diesen Zweck eignen. In dieser Arbeit wurden Koffein, Methylphenidat, Modafinil und Ghrelin hinsichtlich ihrer Wirkungen auf verschiedene kognitive Domanen gesunder Probanden (Logik, Aufmerksamkeit, Arbeitsgedachtnis, Informationsverarbeitung, Kreativitat und Lernen bzw. Gedachtnisbildung) untersucht. Zu diesem Zweck wurden zwei Studien an der Klinik fur Psychiatrie und Psychotherapie der Charite Berlin (Stimulanzienstudie) und dem Max Planck Institut fur Psychiatrie Munchen (GHREEN Studie) durchgefuhrt, wobei meine personliche Leistung zum einen in der Betreuung und Durchfuhrung sowie der Auswertung der kognitiven Ergebnisse der GHREEN Studie bestand, zum anderen in der anschliesenden Gegenuberstellung der vier Testsubstanzen untereinander hinsichtlich Kognition. Beide Studien basierten auf einem randomisierten, doppelt verblindeten, intraindividuellen Studiendesign. Wahrend im Rahmen der Berliner Stimulanzienstudie in einem dreiarmigen Studiendesign mit je 16 Probanden pro Testarm Koffein, Methylphenidat und Modafinil untersucht wurden, beschaftigte sich die GHREEN Studie in Munchen mit einer Fallzahl von 21 Probanden isoliert mit dem Einfluss von Ghrelin auf Kognition. Koffein ist eine im Alltag ubiquitar anzutreffende Substanz, welche aufgrund ihrer Wirkung als Adenosin Antagonist im ZNS eine allgemein wachsamkeitsfordernde Wirkung entfaltet. Methylphenidat wirkt als amphetamin verwandte Substanz im ZNS vorrangig durch eine indirekte Konzentrationserhohung von Dopamin und Noradrenalinspiegeln und wird therapeutisch bei ADHS Patienten zur Verbesserung der Konzentrationsfahigkeit und bei Narkolepsie zur Behandlung von Schlafanfallen wahrend des Tages eingesetzt (Fachinformation Ritalin (Novartis) 2018) Modafinil entfaltet im ZNS komplexe Wechselwirkungen mit verschiedenen Neurotransmittersystemen, einerseits katecholaminassoziiert vergleichbar mit Methylphenidat, andererseits auch hinsichtlich Serotonin, Glutamat und Histamin. Modafinil wird zur Behandlung der exzessiven Schlafrigkeit bei Narkolepsie eingesetzt, da die Substanz die Wachheit bei verschiedenen Spezies einschlieslich des Menschen erhoht (Fachinformation Vigil (TEVA) 2015) Ghrelin entfaltet als orexigenes Neuropeptid, welches masgeblich an der Hunger und Stoffwechselregulation des menschlichen Organismus beteiligt ist, auch in mehreren ZNS Regionen wie Hippocampus und Amygdala seine Wirkung, wobei die exakten Signalwege diesbezuglich noch nicht im Detail bekannt sind. Ghrelin stellte damit unter den vier getesteten Substanzen den am starksten experimentell gepragten Ansatz dar. Fur alle vier Testsubstanzen konnten in fruheren Studien bereits Effekte auf dem Gebiet Kognition nachgewiesen werden, allerdings gelangten diese zu teils kontraren und inkonsistenten Ergebnissen, welche bisher keine eindeutigen Aussagen uber das kognitive Wirkprofil der Testsubstanzen, v.a. hinsichtlich gesunder Probanden, erlaubten: Fur Koffein lag bisher am meisten Evidenz fur einen Effekt in den Bereichen Aufmerksamkeit und Reaktionszeit vor, wahrend Methylphenidat in fruheren Studien die schlussigsten Ergebnisse im Bereich Arbeitsgedachntis und Informationsverarbeitung zeigte. Fur Modafinil konnte in mehreren Studien ein positiver Effekt hinsichtlich komplexer kognitiver Aufgabenstellungen wie z.B. Planungsfahigkeit und Lernvorgange nachgewiesen werden. Ghrelin zeigte im Tiermodell positive Wirkungen im Bereich Gedachtnisformation, wahrend fur den Menschen hinsichtlich Ghrelin und Kognition bis dato kaum Studienergebnisse vorlagen. Auf Grundlage dieses Forschungsstands wurden im Rahmen der beiden Studien in Berlin und Munchen die Auswirkungen der einzelnen Testsubstanzen auf verschiedene kognitive Bereiche anhand einer gemeinsamen kognitiven Testbatterie verglichen. Dem intraindividuellen Studiendesign folgend durchliefen samtliche Probanden zwei identisch aufgebaute Testblocke, davon in randomisierter Zuordnung einmal unter Einfluss eines Placebos und einmal unter Einfluss der jeweiligen Testsubstanz. In die beiden Studien wurden ausschlieslich gesunde, mannliche Probanden im Alter von 20 bis 35 Jahren eingeschlossen. Die Verabreichung der jeweiligen Testsubstanz erfolgte im Falle der Stimulanzienstudie als einmalige, oral applizierte Dosis von 20 mg unretardiert wirkendem Methylphenidat, 200 mg Modafinil bzw. 200 mg Koffein. Im Rahmen der GHREEN Studien hingegen erfolgte die Verabreichung der Testsubstanz aufgrund der kurzen Halbwertszeit von Ghrelin aufgeteilt auf zwei Dosen 100 mg Acyl Ghrelin gelost in 5 ml Aqua ad injectabilia, welche im Abstand von ca. 30 Minuten jeweils in Form eines intravenos applizierten Semibolus uber 2 3 Minuten verabreicht wurden, sodass jeder Proband am Tag der Ghrelin Verumbedingung 200 mg Acyl Ghrelin verabreicht bekam. Die kognitive Testung umfasste zum einen eine Lern bzw. Gedachtnisaufgabe mit nur visuellen (GHREEN) bzw. visuellen und auditiven (Stimulanzienstudie) Lerninhalten, welche zu einem spateren Zeitpunkt im Rahmen eines sog. Recalls erneut abgefragt wurden. Zum anderen eine gemeinsame kognitive Testbatterie bestehend aus funf neuropsychologischen Tests (Bochumer Matrizentest, Psychomotorischer Vigilanztest, Zahlen Verbindungs Test, Reverse Digit Span Test, Alternative uses Test) welche die Wirkung auf verschiedene kognitive Domanen abbilden sollten. Die Ergebnisse der Stimulanzienstudie zeigten fur Koffein einen signifikanten Effekt im Bereich Aufmerksamkeit und Reaktionszeit sowie beim Lernen auditiver Lerninhalte im sog. direkten Free Recall, also einer unmittelbaren Abfrage der Lerninhalte direkt im Anschluss an die eigentliche Lernaufgabe, bei der die Probanden ohne Vorgaben alle Begriffe nennen sollten, welche sie noch erinnern konnten. Methylphenidat fuhrte einerseits zu einem positiven Effekt im Bereich Kreativitat, andererseits hinsichtlich dem Lernen visueller und auditiver Inhalte sowohl im direkten Free Recall als auch im Rahmen des zeitversetzten Free Recalls 24 Stunden spater. Unter Modafinileinfluss kam es zu einem isolierten Effekt auf die Prazision des Lernens im Rahmen des unmittelbaren Free Recalls auditiver Lerninhalte. Im Rahmen der GHREEN Studie zeigten sich unter Ghrelineinfluss keinerlei Effekte hinsichtlich der getestenen kognitiven Domanen. Auf Basis dieser Ergebnisse liesen sich fur Koffein, Methylphenidat und Modafinil selektive Wirkungen, primar in den Bereichen Lernen, Aufmerksamkeit und Kreativitat, nachweisen. Dies scheint von besonderem Interesse, da die vier Testsubstanzen im Rahmen dieser Arbeit erstmals direkt hinsichtlich ihrer Wirkung auf kognitive Domanen gegenubergestellt wurden. Bezuglich Ghrelin war GHREEN die erste systematische Studie, welche den Ansatz verfolgte, die aus tierexperimentellen Modellen gewonnenen Erkenntnisse im Bereich Kognition, auf menschliche Probanden zu ubertragen, sodass auch das Fehlen signifikanter Ergebnisse unter Ghrelineinfluss eine wichtige Erkenntnis darstellt. Die Frage nach dem kognitiven Wirkprofil der vier Testsubstanzen und deren Qualitaten als Kognitive Enhancer muss differenziert beantwortet werden. In Zusammenschau mit dem bisherigen Forschungsstand deuten die erhobenen Ergebnisse darauf hin, dass Koffein, Methylphenidat, Modafinil und Ghrelin wohl keine globalen Kognitiven Enhancer im Sinne von Substanzen, welche allgemein das kognitive Leistungsniveau steigern, darstellen, sondern passend zu den spezifischen Effekten der beiden Studien selektiv auf einzelne kognitive Teildomanen wirken.

Complementology had known difficult moments like the suicide of Louis Pillemer by swallowing the reagents of his laboratory following the criticisms of his discovery by Robert A.

This alternative complement pathway continues to revolutionize medicine by its implications as the principal component of immunosurveillance and as an amplification loop for plasma proteolytic cascades. Moreover, the drug designed in pathologies related to this pathway, eculizumab, was the most expensive drug in the world at the beginning of its marketing. Complementology promises great hopes in inflammatory and degenerative diseases, regenerative medicine, transplantation, and vector nanotechnology and as a diagnostic tool primarily in transplantation and inflammatory imaging.

This can not only reduce the scanning cost and ease patient burden, but also potentially reduce motion artefacts and the effect of contrast washout, thus yielding better image quality. Different from parallel imaging based fast MRI, which utilizes multiple coils to simultaneously receive MR signals, CS MRI breaks the Nyquist Shannon sampling barrier to reconstruct MRI images with much less required raw data. This paper provides a deep learning based strategy for reconstruction of CS MRI, and bridges a substantial gap between conventional non learning methods working only on data from a single image, and prior knowledge from large training data sets. In particular, a novel conditional Generative Adversarial Networks based model (DAGAN) based model is proposed to reconstruct CS MRI. In our DAGAN architecture, we have designed a refinement learning method to stabilize our U Net based generator, which provides an end to end network to reduce aliasing artefacts. To better preserve texture and edges in the reconstruction, we have coupled the adversarial loss with an innovative content loss. In addition, we incorporate frequency domain information to enforce similarity in both the image and frequency domains.

The downside of multishot MRI is that it is very sensitive to subject motion and even small levels of motion during the scan can produce artifacts in the final magnetic resonance (MR) image, which may result in a misdiagnosis. Numerous efforts have focused on addressing this issue; however, all of these proposals are limited in terms of how much motion they can correct and require excessive computational time. In this paper, we propose a novel generative adversarial network (GAN) based conjugate gradient SENSE (CG SENSE) reconstruction framework for motion correction in multishot MRI. First CG SENSE reconstruction is employed to reconstruct an image from the motion corrupted k space data and then the GAN based proposed framework is applied to correct the motion artifacts. The proposed method has been rigorously evaluated on synthetically corrupted data on varying degrees of motion, numbers of shots, and encoding trajectories.

However, it has several fundamental limitations that call into question its accuracy in many applications. Therefore, there has been intense interest in defining and mitigating the intrinsic limitations of the method. Recent studies have reported that tractography is inherently limited in its ability to accurately reconstruct the connections of the brain, when based on voxel averaged estimates of local fiber orientation alone. Several validation studies have confirmed that tractography techniques are plagued by both false positive and false negative connections. However, these validation studies which quantify sensitivity and specificity, particularly in animal models, have not utilized prior anatomical knowledge, as is done in the human literature, for virtual dissection of white matter pathways, instead assessing tractography implemented in a relatively unconstrained manner. Thus, they represent a worse case scenario for bundle segmentation techniques and may not be indicative of the anatomical accuracy in the process of bundle segmentation, where streamline filtering using inclusion and exclusion regions of interest is common. With this in mind, the aim of the current study is to investigate and quantify the upper bounds of accuracy using current tractography methods. Making use of the same dataset utilized in two seminal validation papers, we show that prior anatomical knowledge in the form of manually placed or template driven constraints can significantly improve the anatomical accuracy of estimated brain connections. Thus, we show that it is possible to achieve a high sensitivity and high specificity simultaneously, and conclude that current tractography algorithms, in combination with anatomically driven constraints, can result in reconstructions which very accurately reflect the ground truth white matter connections.", "corpus_id": 221200131, "venue": "Brain Structure and Function", "year": 2020, "author_names": [ "Kurt G Schilling", "Laurent Petit", "Francois Rheault", "Samuel W Remedios", "Carlo Pierpaoli", "Adam W Anderson", "Bennett A Landman", "Maxime Descoteaux" ], "n_citations": 19, "n_key_citations": 0, "score": 0 }, { "doc_id": "216033877", "title": "Deep variational network for rapid 4D flow MRI reconstruction", "abstract": "Phase contrast magnetic resonance imaging (MRI) provides time resolved quantification of blood flow dynamics that can aid clinical diagnosis.

In this paper we introduce a general framework that preserves the spectral information from spatially resolved multidimensional data. Equal weight is given to significant spectral components at the single voxel level, resulting in a summarized image spectrum. This spectrum is then used to define spectral regions of interest that are utilized to reconstruct images of sub voxel components.

A time efficient strategy to acquire high quality multi contrast images is to accelerate individual sequences and then reconstruct undersampled data with joint regularization terms that leverage common information across contrasts.

Such leakage of features may appear as artificial tissues, thereby misleading diagnosis. The goal of this study is to develop a compressive sensing method for multi channel multi contrast magnetic resonance imaging (MRI) that optimally utilizes shared information while preventing feature leakage. Joint regularization terms group sparsity and colour total variation are used to exploit common features across images while individual sparsity and total variation are also used to prevent leakage of distinct features across contrasts. The multi channel multi contrast reconstruction problem is solved via a fast algorithm based on Alternating Direction Method of Multipliers. The proposed method is compared against using only individual and only joint regularization terms in reconstruction. Comparisons were performed on single channel simulated and multi channel in vivo datasets in terms of reconstruction quality and neuroradiologist reader scores. The proposed method demonstrates rapid convergence and improved image quality for both simulated and in vivo datasets.

The two types of muscles are arranged to act antagonistically and this means that by raising the pressure in all of the pneumatic muscles, the stiffness of the system can be increased without a resulting change in finger position.

In this paper, we demonstrated a two dimensional mechanical model for a tendon actuated, notched DCM with compliant joints. The model predicted deformation of the DCM accurately in the presence of tendon force, friction force, and external force. A partition approach was proposed to describe the DCM as a series of interconnected rigid and flexible links. Beam mechanics, taking into consideration tendon interaction and external force on the tip and the body, was applied to obtain the deformation of each flexible link of the DCM. The model results were compared with experiments for free bending as well as bending in the presence of external forces acting at either the tip or body of the DCM. The overall mean error of tip position between model predictions and all of the experimental results was 0.62 0.41 mm. The results suggest that the proposed model can effectively predict the shape of the DCM.", "corpus_id": 6185920, "venue": "IEEE/ASME Transactions on Mechatronics", "year": 2017, "author_names": [ "Anzhu Gao", "Ryan J Murphy", "Hao Liu", "Iulian Iordachita", "Mehran Armand" ], "n_citations": 42, "n_key_citations": 0, "score": 0 }, { "doc_id": "27889360", "title": "The SSSA MyHand: A Dexterous Lightweight Myoelectric Hand Prosthesis", "abstract": "The replacement of a missing hand by a prosthesis is one of the most fascinating challenges in rehabilitation engineering.

BACKGROUND TO THE STUDY he use of drug is as old as man himself. In itself, the use of drugs does not cause any harm. They are for curing and healing, thus promoting better health condition. In order word drugs properly used have been a medical blessing (Maithya, 2009) Over the past few decades, the use of illegal drugs has increased at higher rate in almost every part of the world. According to a United Nations Office on Drugs and Crime Report (2005) reveals that some 200 million people, or 5 percent of the total world`s population age 15 64 have used drugs at least once in the last 12 months and implied 15 million people more than the 2004 estimate. Every country in the world experienced substantial costs as a result of damages caused by substance abuse (World Drug Report, 2005) Despite numerous efforts and sensitizations campaigns to curtail drug abuse in Africa, the region remains a major supplier of some drugs such as cannabis, which is regarded as one of the most widely abused drugs in the world (Maithya, 2009) The World Drug Report by UNODC (2005) reveals that there were about 141 million drug abusers globally including 8 million heroin addicts, 30 million amphetamine users and 13 million cocaine users. The report further indicates that in USA and Canada about 360,000 were heroin users in 1991, and 600,000 in the year 2000. This shows that there was a serious increase of drug abusers worldwide. A reports by Kadiri in 2012 clearly reveals that, in UK, Ireland, Denmark and Italy, 2 percent of 16 and 17 years old had use abuse drugs, while 6 percent of America young people including students of secondary schools had used cocaine. Drug abuse is regarded as one of the current issues of our time threatening peace, stability, good citizenship and human development not only in Nigeria, Africa but also globally. The abuse of drugs can devastate not only the individual, family but the society at large. Since society needs effective citizen who can participate and contribute to its growth, abuse of drugs negates this purpose and rather puts a burden on society that deflates its values resources and creates a measure. Drug abuse does not only mean the abuse of ordinary every day prescribed drugs in the hospital. It specifically refers to the illegal use of such dangerous substance as Marijuana, LSD, heroin, cocaine, opium and other socially disapproved drugs (Kadiri, 2012) Addiction to these drugs has been the major challenge in the society. It has been identified that the large number of psychiatric patients in our hospitals and those on streets and rehabilitation centers has to a large extent resulted from drug addiction (Olley, 2009) For example, a single dose of Indian hemp has been found to produce severe psychological responses. These include anxiety which may lead to panic, depressed mood, sense of unreality pertaining to one self or to surroundings, illusions, hallucinations, paranoid ideas and delirium (Obot, 2005).This unfortunate situation has become a serious concern in Nigeria. It is in line with this, that United Nations Organization has urged member countries to co operate and take appropriate local measures to check the increasing wave of drug abuse. The Nigerian government has accordingly established agencies and other institutions to deal with the drug abuse issue. Those experiencing drugs problem live with disruption in their lives. Drug abuse has a negative impact on the education of secondary school students. T International Journal of Research and Innovation in Social Science (IJRISS) |Volume III, Issue I, January 2019|ISSN 2454 6186 www.rsisinternational.org Page 72 The overall health of the user is affected negatively and behaviours associated with drug abuse predispose the abuser to crime and contagious diseases including HIV/AIDS (Cookson,H 1992) They often experience physical illnesses, such as damage to important organs of the body like brain, liver and lungs, hypertension, cardiovascular disease, damage to un born child when drugs are used during pregnancy. Abusers of drugs experience psychological traumas, such as sleeplessness, anxiety, loss of memory, hallucinations, depression and psychosis. Many social problems are associated with drug abuse and drug users experience problems which disrupt their personal, social and economic life. These include loss of job, family disintegration, expulsion from school, delinquency, criminal offence which includes stealing, rape, murder, prostitution among others. Report had shown that drugs are found in almost all cities in Nigeria, motor parks, street corners, joints on campuses, uncompleted buildings and under flyovers. A nationwide survey of secondary school students reveals that 65 percent of the students in Nigeria used drugs to have good time with their friends, 54 percent wanted to experiment to see what it like, 20 percent to 40 percent used it to alter their moods, to feel good, to relax, to relive tension and to overcome boredom and problem (Obot, 2005) Majority of secondary schools students ignorantly depend on one form of drug or the other from various daily activities, social, educational, political, moral etc. Such drugs include: Tobacco, Indian hemp, Cocaine, Morphine, Heroine, Alcohol, Ephedrine, Glue, Barbiturates and Amphetamines. Recent statistics in Nigeria indicates that one in every three secondary school students consumes alcohol while 8.3 percent smoke cigarettes and almost one in every ten chew Miraa, About 3 percent smoke bhang, and use hard drugs like Cocaine. According to Olley (2009) use of alcohol contributes 25% of the total explanatory power of sexual risky behavior among adolescent which expose them a high risk of HIV/AIDS and other infectious diseases (WHO) II. STATEMENT OF THE PROBLEM Drugs abuse in our schools and colleges has today become a very serious menace in Nigerian system of education despite the various measures that are being taken to remedy the incidence .In some secondary schools; drugs abuse has remained a tradition by students despite all effort by the management of the schools to curtail/eradicate the act. Drugs free club and parents' teachers association (PTA) have also been carrying out lectures/mobilization on the dangers of abusing drugs, yet students fall victims of drugs abuse at all times. The Nigerian government has established agencies such as drugs law enforcement agency and other agencies to deal with drugs problems but unfortunately the menace is still increasing day in day out hence, the need to carry out the study. The purpose of the study was to investigate school principals' perceived effects of drugs abuse among students of day secondary schools in the study area. The following objectives were formulated for the study: To identify the causes of drugs abuse among students of day secondary schools. To examine the extent to which drugs abuse affects students of day secondary schools in the study area To propose strategies that would be adopted to minimize drug abuse in day secondary schools. III. RESEARCH METHODOLOGY Descriptive survey design was used. The descriptive survey design is the most frequent used method for collecting information about people`s opinion, habits, or any of the variety of education or social science issues (Kombo Tromp 2006).This design is preferred since the study aims at sampling secondary schools principals as participant of the study. According Orodho (2004) a descriptive survey design is a method of collecting information by administrating a questionnaire to a sample of individuals. This design aimed at obtaining pertinent and precise information concerning the current status of a phenomenon and whatever possible to draw a valid general conclusion from the facts discovered (Gay 1976, Kombo &Tromp 2006) A descriptive survey design was chosen because the researcher sought to describe the effects of drugs abuse on students of day secondary schools in Bauchi Senatorial District. The target populations for the study were all the 120 principals of day secondary schools in Bauchi Senatorial District. The sample size consisted of 40 school principals.

In the rural community of Kano State, Nigeria, information on haematological changes in human malaria was scanty in spite of their role in the pathophysiology of malaria. This cross sectional study was undertaken to determine blood cell profiles in malaria patients attending a rural hospital in malariaendemic region. Methods: Blood samples (3 ml each) were collected in EDTA containers from 150 randomly selected outpatients attending Gaya General Hospital, screened for malaria using RDT kit (CareStart Malaria HRP 2, Access Bio Inc. USA) based on Histidine rich protein 2 (PfHRP 2) and blood cell profiles determined using automated Sysmex haematologic analyser.

Platelet counts recorded 179.24x109/L and 230.47x109/L (P<0.05) Sociodemographic factors such as level of education, occupation and marital status did not significantly influence malaria prevalence. Interpretation: Low PCV and Hb in malaria patients indicate mild anaemia due to malaria related haemolysis. The occurrence of thrombocytopenia may be due to other underlying pathology as further studies with larger sample size are needed to ascertain the cause of low platelet counts in malaria patients in the study area.", "corpus_id": 214389041, "venue": "", "year": 2019, "author_names": [ "M U Ali", "Ankeet Panda", "Sani Mohammed Yahaya", "Umar Aliyu Umar", "M S Inuwa", "Ya'u Sabo Ajingi", "S Idris" ], "n_citations": 0, "n_key_citations": 0, "score": 0 }, { "doc_id": "4874580", "title": "Adolescent depressive symptoms in India, Australia and USA: Exploratory Structural Equation Modelling of cross national invariance and predictions by gender and age.", "abstract": "BACKGROUND The present study compares depressive symptoms in adolescents from three countries: Mumbai, India; Seattle, United States; and Melbourne, Australia measured using the Short Moods and Feelings Questionnaire (SMFQ) The study cross nationally compares SMFQ depressive symptom responses by age and gender. METHODS Data from a cross nationally matched survey were used to compare factorial and measurement characteristics from samples of students from Grade 7 and 9 in Mumbai, India (n=3268) with the equivalent cohorts in the Washington State, USA (n=1907) and Victoria, Australia (n=1900) Exploratory Structural Equation Modelling (ESEM) was used to cross nationally examine factor structure and measurement invariance. RESULTS A number of reports suggesting that SMFQ is uni dimensional were not supported in findings from any country. A model with two factors was a better fit and suggested a first factor clustering symptoms that were affective and physiologically based symptoms and a second factor of self critical, cognitive symptoms. The two factor model showed convincing cross national configural invariance and acceptable measurement invariance. The present findings revealed that adolescents in Mumbai, India, reported substantially higher depressive symptoms in both factors, but particularly for the self critical dimension, as compared to their peers in Australia and the USA and that males in Mumbai report high levels of depressive symptoms than females in Mumbai.

Because worry is an important component of anxiety, the accurate measurement of worry is crucial to studying the etiology, prevention and treatment of anxiety disorders. Assessment of the trait worry has emerged as the most widely used strategy to establish the presence and extent of pathological worry. However, the Penn State Worry Questionnaire (PSWQ) the most widely used measure of the trait worry, has not been validated cross culturally in groups outside of the U.S.A. METHODS We tested the psychometric properties and measurement invariance of an 8 item abbreviated version of the PSWQ (PSWQ A) in American (N 206) and Spanish (N 137) older adult samples. RESULTS Internal consistency was high and analyses supported a unidimensional solution in both samples. Measurement invariance was tested using confirmatory factor analysis (CFA) and Rasch models. Results of the CFA suggest that measurement invariance between the samples can be assumed for women but not for men. Rasch modeling results by gender suggested that three items have different endorsability levels in the two samples, suggesting that certain items may more closely represent the construct of the trait worry in American and Spanish older adults.

The impact of musical interests on the ability to distinguish between emotions or valence (on an axis positivity neutrality negativity) from voice samples was studied. Listening tests were conducted on location in five countries: Estonia, Finland, Russia, Sweden, and the USA with 50 randomly chosen participants (25 males and 25 females) in each country. The participants (total N 250) completed a questionnaire eliciting their background information and musical interests. The responses in the listening test and the questionnaires were statistically analyzed. Voice quality parameters and the share of the emotions and valence identified correlated significantly with each other for both genders. The percentage of emotions and valence identified was clearly above the chance level in each of the five countries studied, however, the countries differed significantly from each other for the identified emotions and the gender of the speaker. The samples produced by females were identified significantly better than those produced by males. Listener's age was a significant variable. Only minor gender differences were found for the identification. Perceptual confusion in the listening test between emotions seemed to be dependent on their similar voice production types.

This study was guided by role theory. The research was explanatory and follows a cross sectional survey design. The total population for this study was 4,465 employees and managers of five star rated hotels in Nairobi City County. The desired sample size was 196 respondents. The study used structured questionnaires as the main instruments for collecting primary data from respondents and in some instances document analysis was used as source of secondary data. The researcher used drop and pick method while administering questionnaires to the respondents. The data was analyzed quantitatively using the Statistical Package for Social Scientists (SPSS) to obtain descriptive statistics and inferential statistics. Data collected was first edited, formatted and organized for coding into the SPSS data viable table. The study hypothesis was tested using multiple linear regression analysis. This study revealed that work life balance significantly influenced career salience in five star hotels in Kenya. The study concluded that employees working in organisations where priority is also given to their other aspects of life other than work commitments feel more satisfied and engaged in their work. Therefore work life balance is an essential component in ensuring career salience among employees. The study recommended that companies should have adequate work life balance policy that include leave days, provision for maternity leave that would go a long way in ensuring people continues with their normal life besides work. The best work life balance is different for each of employees because we all have different priorities and different lives therefore work life balance should in a manner that accommodates everyone.

In this conceptual paper, we explore the implications of digital transformation on enterprise architecture.

There are just too many threats. This article presents seven practical steps to achieving cyber resilience. Cyber resilience is not a traditional defensive stance. It requires a change in the way organizations approach security of its information and communication technology (ICT) asset base. Cyber resilience is integrated into the \"bones\" of the organization and requires the organization to develop a well defined, explicit architecture of controls to ensure cyber resiliency. The controls assure provable protection of critical ICT assets and their various interdependencies from every form of electronic, human and physical threat; inside and outside the enterprise's eco system. Cyber resilient architectures make attacks less likely to succeed, minimize the consequences when they do, increase the work factor cost and uncertainty for the adversary, and possibly act as a deterrent against future attacks. Cyber resilience is enforced as an organizational condition rather than a deployed set of explicit countermeasures. This goal requires that a robust set of concrete controls are embedded in the enterprise architecture. Effective implementation of a cyber resilient enterprise architecture requires strategic vision. It also requires day to day engagement across the enterprise to ensure that the controls that enable cyber resilience are effective.", "corpus_id": 62985006, "venue": "", "year": 2017, "author_names": [ "William Arthur Conklin", "Dan Shoemaker" ], "n_citations": 1, "n_key_citations": 0, "score": 0 }, { "doc_id": "199448594", "title": "Selected Topics on Business Informatics: Editorial Introduction to Issue 19 of CSIMQ", "abstract": "The objective of this thematic issue was twofold.

This article offers a framework for evaluating the long run economic consequences of various possible scenarios: it uses an overlappinggenerations, general equilibrium model of the French economy. After the description of the model, we present the results of two demographic variants, which clearly show that the current system would be sustainable in the long run only if population growth is positive. Finally the comparison of macroeconomic outcomes and the individual and social welfare analysis suggest that, if the forecast of a stagnating French population comes true, raising the legal retirement age would clearly dominate other alternatives such as curtailing benefits or switching to a pure capitalization scheme. Key words: computable overlapping generations models, public pensions, ageing. JEL classification: D58, H55. Some recent French studies (INSEE, 1990; Cornilleau and Sterdyniak, 1991; Liv re blanc 1991) have evaluated the prospective financial requirements of the French pension system. These studies rely on the official demographic projections (Dinh and Lab at, 1986) and strong assumptions about the future values of many macroeconomic variables. The increase in social contribution rates ensuring the financial equilibrium of the public pension fund is then calculated, but feedbacks from these institutional prospects to the economic equilibrium are ignored.

France, and other French speaking countries, very quickly adhered to the approach of the founding fathers of regional science. French language research developed for several years without maintaining major relations with the main streams that flow through regional science. However, the years 2000 and 2010 saw the emergence of streams of thought that strongly irrigate at the international level. The authors of this paper are part of this movement. Here we trace the origins and development of the French speaking contribution to regional sciences, while highlighting the originality of the French language approach. First, the question of academic and institutional contexts is discussed, with the role of the founders and the peculiar place of Journals and public institutions. Further sections analyse the main contributions coming from economics (local systems of production and innovation, innovative milieus and proximity analysis) and geography (regional development at a global scale, and urban systems and complexity) We conclude with crossdisciplinary contributions including intra urban organization and mobility, territorial governance and territorial development, as well as other approaches to the social sciences, in the contemporary issues of city and territorial governance.", "corpus_id": 213855769, "venue": "", "year": 2020, "author_names": [ "Denise Pumain", "Andre Torre" ], "n_citations": 3, "n_key_citations": 0, "score": 0 }, { "doc_id": "230668029", "title": "The Belle Epoque of the railways: the Freycinet plan and its effects on the French population and economy", "abstract": "In this paper, I study the impact of the Freycinet plan (1879 1914) on the French population and economy,in the short run.The Freycinet plan was one of the major public works programmes launched by the young Third Republic in 1878 1879, which aimed to massively develop rail way connections across the French territory.

Online help seeking may offer an additional domain where young people can seek aid for mental health difficulties, yet our current understanding of how young people seek help online is limited. Objective This was an exploratory study which aimed to investigate the online help seeking behaviors and preferences of young people. Methods This study made use of an anonymous online survey. Young people aged 18 25, living in Ireland, were recruited through social media ads on Twitter and Facebook and participated in the survey. Results A total of 1308 respondents completed the survey. Many of the respondents (80.66% 1055/1308) indicated that they would use their mobile phone to look online for help for a personal or emotional concern. When looking for help online, 82.57% (1080/1308) of participants made use of an Internet search, while 57.03% (746/1308) made use of a health website. When asked about their satisfaction with these resources, 36.94% (399/1080) indicated that they were satisfied or very satisfied with an Internet search while 49.33% (368/746) indicated that they were satisfied or very satisfied with a health website. When asked about credibility, health websites were found to be the most trustworthy, with 39.45% (516/1308) indicating that they found them to be trustworthy or very trustworthy. Most of the respondents (82.95% 1085/1308) indicated that a health service logo was an important indicator of credibility, as was an endorsement by schools and colleges (54.97% 719/1308) Important facilitators of online help seeking included the anonymity and confidentiality offered by the Internet, with 80% (1046/1308) of the sample indicating that it influenced their decision a lot or quite a lot. A noted barrier was being uncertain whether information on an online resource was reliable, with 55.96% (732/1308) of the respondents indicating that this influenced their decision a lot or quite a lot. Conclusions Findings from this survey suggest that young people are engaging with web based mental health resources to assist them with their mental health concerns.

To assist secondary schools, the Black Dog Institute has developed an online, school based, mental health service (Smooth Sailing) Delivered in the classroom, Smooth Sailing uses a website to screen, assess, allocate, and deliver care for depression and anxiety. The service is based on the principles of stepped care, offering treatments with varied intensity and follow up by a school counselor when necessary. The current study aimed to evaluate the feasibility, acceptability, and safety of this new type of service among secondary school students. Methods: Between February and June 2017, a single arm, pre post, pilot study was conducted among students from four NSW secondary schools. Schools were given access to the service for 6 weeks. Feasibility measures (consent rates and step allocations) acceptability measures (service use and satisfaction) and safety measures (deterioration in help seeking intention scores and mental health symptoms) were assessed at baseline and completion of the 6 week trial period. Results: A total of 59 students took part in the service pilot (mean age, 14.57 years; SD, 0.89 years; range, 13 16 years) At baseline, 18.64% of students were found to require follow up from the school counselor, and 80% of these were new cases. Although completion of the online modules was low, service satisfaction was high. At 6 weeks, the mean scores for help seeking, depression, and anxiety remained relatively stable or improved. Conclusions: The current study presents important findings for the development and implementation of an online mental health service that screens students' mental health and allocates care accordingly, all within the school setting. Although the findings provide some support for the feasibility, acceptability, and safety, service improvements are needed.

RESULTS The nonpsychotic relatives showed no impairment on the forward digit span task, a measure of general attention, but did show impairment on the backward digit span task, a measure of verbal working memory. Schizophrenia patients showed impairment on both the forward and backward digit span tasks.

PAF also varies within individuals across developmental stages, among different cognitive tasks, and among physiological states induced by administration of various substances. The present study suggests that, among other things, PAF reflects a trait or state of cognitive preparedness. METHODS Experiment 1 involved 19 channel EEG recordings from 10 individuals with traumatic brain injury (TBI) and 12 healthy matched controls, before, during, and after tasks of visual and auditory attention. Experiment 2 involved EEG recordings from 19 healthy young adults before and after a working memory task (WAIS R Digit Span) repeated on 2 different days to measure within individual differences. RESULTS Experiment 1 showed significantly lower PAF in individuals with TBI, mostly during post task rest. Experiment 2 showed PAF during pre task baseline to be significantly correlated with Digit Span performance of the same day but not with Digit Span performance of another day. Moreover, PAF was significantly increased after Digit Span for those participants whose PAF was lower than the sample median before the task, but not for those who had it higher. Finally, both PAF and Digit Span performance were increased during the second day. CONCLUSIONS PAF was shown to detect both trait and state differences in cognitive preparedness, as well as to be affected by cognitive tasks.

A formal test of curvilinear relationships for P300 latency/amplitude and age was performed. Principal component factor analyses were performed for P300 latency and amplitude separately in order to check for possible superordinate structures in the distribution of the electrical activity measured at the scalp. In addition, each of the electrodes and each of the factors were correlated with the different neuropsychological measures, and the contribution of age to the observed relationships is discussed. The main conclusion drawn is that the activity generated from different brain areas change at different rates with age. While the posterior area shows a clear reduction of P300 amplitude and a delay of P300 latency with age, the amplitude does not decrease at the same rate in the fronto central areas, and there is at the same time a marked hemispheric asymmetry in the age dependent change of activation. Based on our data, it may be concluded that a curvilinear expression generally does not explain the aging effect on the ERP component P300. Correlations between neuropsychological measures and P300 did, as expected, vary with area of activation, and the strongest correlations were generally found between matrices, block design and digit span, and the midline and left fronto temporal electrodes.

In NF1 patients, neurological issues may result from damaged myelin, and mice with a neurofibromin gene (Nf1) mutation show white matter (WM) defects including myelin decompaction. Using mouse genetics, we find that altered Nf1 gene dose in mature oligodendrocytes results in progressive myelin defects and behavioral abnormalities mediated by aberrant Notch activation. Blocking Notch, upstream mitogen activated protein kinase (MAPK) or nitric oxide signaling rescues myelin defects in hemizygous Nf1 mutants, and pharmacological gamma secretase inhibition rescues aberrant behavior with no effects in wild type (WT) mice. Concomitant pathway inhibition rescues myelin abnormalities in homozygous mutants. Notch activation is also observed in Nf1+ mouse brains, and cells containing active Notch are increased in NF1 patient WM. We thus identify Notch as an Nf1 effector regulating myelin structure and behavior in a RASopathy and suggest that inhibition of Notch signaling may be a therapeutic strategy for NF1.", "corpus_id": 4904615, "venue": "Cell reports", "year": 2017, "author_names": [ "Alejandro Lopez-Juarez", "Haley E Titus", "Sadiq H Silbak", "Joshua W Pressler", "Tilat A Rizvi", "Madeleine Bogard", "Michael R Bennett", "Georgianne M Ciraolo", "MichaelT Williams", "Charles V Vorhees", "Nancy Ratner" ], "n_citations": 22, "n_key_citations": 1, "score": 1 }, { "doc_id": "46797229", "title": "Oligodendrocyte RasG12V expressed in its endogenous locus disrupts myelin structure through increased MAPK, nitric oxide, and notch signaling", "abstract": "Costello syndrome (CS) is a gain of function Rasopathy caused by heterozygous activating mutations in the HRAS gene.

Here, we studied a mouse model in which the endogenous HRas gene is conditionally replaced by mutant HRasG12V in mature oligodendrocytes, to separate effects in mature myelinating cells from developmental events. Increased myelin thickness due to decompaction was detectable within one month of HRasG12V expression in the corpus callosum of adult mice. Increases in active ERK and Nitric Oxide (NO) were present in HRas mutants and inhibition of NO synthase (NOS) or MEK each partially rescued myelin decompaction. In addition, genetic or pharmacologic inhibition of Notch signaling improved myelin compaction.

Several neurological diseases, such as multiple sclerosis, are characterized by myelin damage, which is responsible of severe functional impairment. Myelin repair requires the timely recruitment of adult oligodendrocyte precursor cells (OPCs) at the lesion sites, their differentiation and maturation into myelinating oligodendrocytes. As a consequence, OPCs undergo profound changes in their morphology, functions, and interactions with other cells and extracellular environment, thus requiring the reorganization of both their lipid metabolism and their membrane composition, which is substantially different compared to other plasma membranes. Despite the growing knowledge in oligodendroglia biology and in the mechanisms involved in OPC mediated regeneration, the identification of strategies to promote remyelination still remains a challenge. Here, we describe how altered lipid metabolism in oligodendrocytes influences the pathogenesis of demyelination, and we show that several FDA approved drugs with a previously unknown remyelination potential do act on cholesterol and lipid biosynthetic pathways.

These phenomena triggered an increasing number of studies over the functions lipid exert to shape and maintain myelin, and brought to the finding that lipids are more than only structural building blocks. They act as signaling molecules to drive proliferation and differentiation of oligodendrocyte progenitor cells, as well as proliferation of premyelinating oligodendrocytes, and their maturation into myelinating ones.

Among all reported nodal ECM components, the antiserum exhibited strong cross reactivity against versican V2 isoform, a chondroitin sulfate proteoglycan. Furthermore, the OMgp antiserum labeled OMgp null nodes, but not nodes from versican V2 deficient mice, and preadsorption of the OMgp antiserum with recombinant versican V2 blocked nodal labeling. Analysis of CNS nodes in OMgp null mice failed to reveal any nodal or paranodal defects, or increased nodal collateral sprouting, indicating that OMgp does not participate in CNS node of Ranvier assembly or maintenance. We successfully identified a highly specific anti OMgp antibody and observed OMgp staining in white matter only after initiation of myelination.

Finally, during calcium overload induced pathology, as occurs in ischemia, mitochondria may buffer calcium or induce apoptosis. Despite their important functions, very little is known of the properties of oligodendrocyte mitochondria, and mitochondria have never been observed in the myelin sheaths. We have now used targeted expression of fluorescent mitochondrial markers to characterize the location and movement of mitochondria within oligodendrocytes. We show for the first time that mitochondria are able to enter and move within the myelin sheath. Within the myelin sheath the highest number of mitochondria was in the cytoplasmic ridges along the sheath. Mitochondria moved more slowly than in neurons and, in contrast to their behavior in neurons and astrocytes, their movement was increased rather than inhibited by glutamate activating NMDA receptors. By electron microscopy we show that myelin sheath mitochondria have a low surface area of cristae, which suggests a low ATP production.
