Situational Victimization Cues Strengthen Implicit and Explicit Self-Victim Associations: An Experiment With College-Aged Adults
Authors: Sachs Nicole M. , Veysey Bonita M. , Rivera Luis M.
Published: May 2020

Contextually salient social identities are those that individuals may not think of often but that may be temporarily activated by relevant situational cues. We hypothesized that victim, one of many identities people may possess, is a contextually salient identity that operates both implicitly and explicitly. To test this hypothesis, the present research tests the effect of a situational victimization cue on implicit and explicit self-victim associations. We utilized an experiment with a 2 (Victimization salience: yes vs. no) × 2 (Past victimization experience: yes vs. no) between-participants design. One hundred eighty-one undergraduate student participants were recruited and randomized into one of two conditions: (a) an experimental condition reminding them of a previous victimization experience or (b) a control condition whereby they did not receive a reminder. All participants then completed one Single-Category Implicit Association Test, and self-report measures of explicit self-victim associations and victimization experience. Between-participants analyses of variance were used to analyze data. Results indicated that individuals who were reminded of a previous victimization exhibited stronger explicit and implicit self-victim associations compared to those who were not reminded. This research provides initial evidence that victim is a contextually salient identity, which has implications for the factors and processes underlying identity formation, revictimization, and the prevention of repeat victimization.
Solidarity Reasoning and Citizenship Agendas: From Socialist Yugoslavia to Neoliberal Serbia
Authors: Vasiljević Jelena
Published: May 2020

Solidarity and citizenship are intertwined in a very complex manner, where the former usually operates as the “social glue” for the latter, holding together its formal components such as rights, duties, and membership criteria. The “we” that sets the parameters for membership and equality is not only legally defined but also discursively produced and maintained. Here, the rhetoric of solidarity plays an important yet ambiguous role, as it can advocate for interdependence and full inclusion while at the same time solidifying the exclusionary “we.” The aim of this article is to show how solidarity reasoning—the question of with whom we should be solidary and why—plays a functional role in maintaining citizenship agendas, and how this reasoning changes to support and enable shifts in these agendas. The dominant solidarity narratives that have supported prevailing citizenship agendas in Serbia (and across the post-Yugoslav space) over the last couple of decades will be discussed, as will counter-narratives that have served to destabilize hegemonic agendas by envisioning citizenship communities differently. Today, the ambiguous role solidarity can play within a citizenship agenda becomes especially obvious in neoliberal regimes, where, as I will show in the case of contemporary Serbia, calls for solidarity can be deployed to foster very distinct, arguably mutually opposing, kinds of political subjectivities and citizen activism.

Published: May 2020

In order to meet the design requirements of friction stir welding equipment, a three-degree-of-freedom rigid-flexible 3UPS-UP-3Cable-Driven (3UPS-UP-3CD) parallel manipulator was applied to the main feed mechanism of the friction stir welding robot. The kinematics analysis of the new parallel manipulator was carried out, and the complete homogeneous dimensional Jacobian matrix of the 3UPS-UP-3CD manipulator was solved. Through kinematic performance analysis, the carrying capacity, dexterity and stiffness of 3UPS-UP-3CD manipulator are obviously better than 3UPS-UP mechanism, and the impact of cables on the workspace can also be eliminated by adjusting the dimension parameter. The composite quality workspace map of the manipulator was drawn, and the composite kinematic performance index was proposed. Multiobjective optimization was completed for 3UPS-UP-3CD manipulator, and its performance was improved. The dynamic analysis of the manipulator was carried out, and the driving forces of two mechanisms were calculated under two trajectories. The results showed that the maximum driving force of 3UPS-UP-3CD manipulator was lower than 3UPS-UP mechanism, which proved that 3UPS-UP-3CD manipulator was more suitable for heavy-duty conditions.
Valuation Analysis of Initial Public Offer (IPO): The Case of India
Authors: Manu K. S. , Saini Chhavi
Published: May 2020

In today’s fast moving and dynamic world, short-term investors face difficulty while choosing which avenue to invest in. Investors view investment in securities as a highly risky avenue due to VUCA (Volatility, Uncertainty, Complexity and Ambiguity) pertaining to future movement of security prices. The study has been carried out to analyse the post-Initial Public Officer (IPO) performance of various companies that have gone public in 2017 using event study methodology. The study also tries to determine whether these IPOs were underpriced in short run and identifies various factors that influence the movement of such IPOs in the short run. The study found that about 70 per cent of the selected IPOs are underpriced in short run and the movement of these IPOs in short run is not influenced by the age of the company, issue size of the IPO, ownership sector and the promoter’s holdings after the issue.
Emerging Pharmacotherapy and Health Care Needs of Patients in the Age of Artificial Intelligence and Digitalization
Authors: Zarowitz Barbara J.
Published: May 2020

Advances in the application of artificial intelligence, digitization, technology, iCloud computing, and wearable devices in health care predict an exciting future for health care professionals and our patients. Projections suggest an older, generally healthier, better-informed but financially less secure patient population of wider cultural and ethnic diversity that live throughout the United States. A pragmatic yet structured approach is recommended to prepare health care professionals and patients for emerging pharmacotherapy needs. Clinician training should include genomics, cloud computing, use of large data sets, implementation science, and cultural competence. Patients will need support for wearable devices and reassurance regarding digital medicine.
Factors Associated With Caregiver–Child Symptom Concordance Among Trauma-Exposed Children
Authors: Wamser-Nanney Rachel , Campbell Claudia L.
Published: May 2020

Concordance in caregivers’ and children’s reports of children’s trauma-related symptoms is often low, and symptom discrepancies are associated with negative clinical implications. The aim of the current study was to examine the degree of concordance between children’s and caregivers’ reports of trauma-related difficulties and determine whether any child or family characteristics were associated with symptom agreement. Three hundred thirteen trauma-exposed children ( M = 9.55, SD = 1.77; 65.2% girls, 51.3% Black) and their nonoffending caregivers seeking treatment were included in the study. Children’s and caregivers’ reports of trauma-related difficulties were related, but low intraclass correlation coefficients indicated poor concordance across symptoms. Child’s gender was associated with levels of concordance for several trauma-related difficulties (e.g., anxiety, depression, anger, dissociation, and sexual concerns), with lower symptom agreement for girls. Child’s age, minority status, and relationship to caregiver emerged as factors related to levels of concordance for certain trauma-related symptoms. Child’s gender, age, minority status, and relationship to caregiver may predict symptom discordance for select trauma-related difficulties, whereas other family factors such as caregiver marital status and income may be unrelated. Given the importance of caregiver–child concordance in treatment success, additional research should investigate other factors that may influence trauma-related symptom agreement.

Published: May 2020

Introduction. The Health Education Specialist Practice Analysis II 2020 (HESPA II 2020) described the contemporary practice of health education specialists across work settings at entry and advanced levels. The purpose of the HESPA II 2020 manuscript was to report the research process and resulting data associated with the HESPA II 2020 and to provide recommendations for future practice analyses in health education. Method. Two data collection instruments were developed with the assistance of a 17-member Health Education Practice Panel to survey practicing health education specialists on the knowledge and skills needed in their ongoing roles. The instruments were designed to assess the degree to which the elements of the model had importance to practice ( Importance), how often health education specialists performed the elements of the model ( Frequency), and the point in time that health education specialists were expected to perform the various elements of the model ( Performance Expectation). Composite scores for Sub-Competencies were calculated and subgroup comparisons were conducted to distinguish between levels of practice. Results. A total of 3,851 health education specialists provided usable responses. The final validated hierarchical model included eight Areas of Responsibility, 35 Competencies, and 193 Sub-Competencies. Of the Sub-Competencies, 114 were Entry level, 59 Advanced 1 level, and 20 Advanced 2 level. In addition, 145 knowledge items were verified. Discussion. HESPA II 2020 produced a validated hierarchical model descriptive of current practice of health education specialists across work settings. The results have implications for professional preparation, professional development, and certification.

Authors: Vargas Veronica , Alio Jorge L , Oliveira Renan F. , Renna Antonio , Yebana Pilar
Published: May 2020

Objective

To evaluate and compare the objective and subjective outcomes after the bilateral implantation of a diffractive bifocal and trifocal intraocular lens.

Methods

This is a case–control, single-center observational study which included 27 patients; 16 patients were implanted bilaterally with the bifocal AcrySof IQ ReSTOR+3.0D and 11 patients with the trifocal AT LISA tri 839MP. Uncorrected visual acuity at distance, intermediate, and near under mesopic and photopic conditions using ETDRS charts with 10% and 100% contrast, corrected distance visual acuity, and binocular defocus curve in photopic conditions; binocular contrast sensitivity under mesopic and photopic conditions for far and near distances were assessed. The Visual Function Questionnaire-25 questionnaire was used to assess patients' satisfaction. All the measurements were performed 6–24 months after cataract surgery.

Results

The ReSTOR group had better binocular uncorrected near visual acuity in photopic conditions with low and high contrast charts ( p = 0.040 and p = 0.033, respectively), as well as in far contrast sensitivity measurement under mesopic conditions with a spatial frequency of 3 cycles per degree ( p = 0.034). There was not a significant difference between the two study groups in uncorrected near, intermediate or distance vision under mesopic conditions. The AT LISA tri study group had better subjective outcomes.

Conclusion

Both intraocular lenses restore visual acuity after cataract surgery. The ReSTOR intraocular lens provides better objective outcomes than the AT LISA tri, although the latter provides better subjective outcomes. The relevance of this study is the evaluation of both objective and subjective outcomes.
Predicting Self-Interacting Proteins Using a Recurrent Neural Network and Protein Evolutionary Information
Authors: An Ji-Yong , Zhou Yong , Yan Zi-Ji , Zhao Yu-Jun
Published: May 2020

Self-interacting proteins (SIPs) play crucial roles in biological activities of organisms. Many high-throughput methods can be used to identify SIPs. However, these methods are both time-consuming and expensive. How to develop effective computational approaches for identifying SIPs is a challenging task. In the article, we present a novel computational method called RRN-SIFT, which combines the recurrent neural network (RNN) with scale invariant feature transform (SIFT) to predict SIPs based on protein evolutionary information. The main advantage of the proposed RNN-SIFT model is that it uses SIFT for extracting key feature by exploring the evolutionary information embedded in Position-Specific Iterated BLAST–constructed position-specific scoring matrix and employs an RNN classifier to perform classification based on extracted features. Extensive experiments show that the RRN-SIFT obtained average accuracy of 94.34% and 97.12% on the yeast and human dataset, respectively. We also compared our performance with the back propagation neural network (BPNN), the state-of-the-art support vector machine (SVM), and other existing methods. By comparing with experimental results, the performance of RNN-SIFT is significantly better than that of the BPNN, SVM, and other previous methods in the domain. Therefore, we conclude that the proposed RNN-SIFT model is a useful tool for predicting SIPs, as well to solve other bioinformatics tasks. To facilitate widely studies and encourage future proteomics research, a freely available web server called RNN-SIFT-SIPs was developed at http://219.219.62.123:8888/RNNSIFT/ including the source code and the SIP datasets.

Authors: Kariyawasam PN , Pathirana KD , Hewage DC , Dissanayake RDA
Published: May 2020

Background:

Health-related quality of life (HRQOL) is an important measure that enables evaluation of rehabilitation outcomes. Stroke and Aphasia Quality of Life Generic Scale–39 (SAQOL-39g) is a disease-specific questionnaire that measures HRQOL of patients with stroke. This study was conducted to adapt the preliminary version of proxy-rated Sinhala version of the SAQOL-39g.

Methods:

The study was conducted with the participation of 115 proxies of the patients with stroke. The SAQOL-39g was translated and back translated, and culturally adapted by evaluating the items of the questionnaire. The culturally adapted scale was evaluated for its internal consistency, test-retest reliability, and validity.

Results:

The mean age of the patients with stroke was 67.07 (standard deviation [SD] = 11.2) years; males comprising two-thirds of the study sample (67% [n = 77]). The proxy-rated Sinhala version of the SAQOL-39g showed excellent internal consistency (α = 0.98 [overall score]), 0.97, 0.96, and 0.95 for physical, communication, and psychosocial domains, respectively. The intraclass correlation coefficient (ICC) was 0.92 for overall, and 0.93, 0.92, and 0.91 for physical, communication, and psychosocial domains, respectively. Factor analysis extracted 3 factors with 72.4% of the variance.

Conclusions:

Proxy-rated Sinhala version of the SAQOL-39g is a psychometrically sound, reliable, and valid tool to assess the post-stroke quality of life of Sinhala-speaking patients with stroke and aphasia.
A novel approach in developing environment-friendly bio-lubricant from coconut oil, mustard oil and its methyl esters
Authors: Akshai B , Visakh R , Kamath Krishnanand J , Riyas Mohammed R , Joy ML
Published: May 2020

The environmental issues caused by synthetic lubricant oils necessitate the need for an environment-friendly lubricant. In this study, a novel approach is proposed for developing an environment-friendly bio-lubricant by blending mustard oil, coconut oil and its methyl esters. Properties of the bio-lubricant are studied and compared with commercial ISO VG 32 oil. The best among various blends prepared are selected based on a decision matrix. The results revealed that this method helps in pour point depression and also in achieving excellent oxidative stability as compared to the base vegetable oil. The newly formulated oil has a pour point lower than that of commercial oil and is found to be highly biodegradable. The anti-wear characteristics of the oil are improved using boric acid, and the viscosity of the oil is improved using ethyl vinyl acetate for meeting the industrial standards. The newly formulated oil complies with industrial standards and can be used as biodegradable lubricant oil.
From language mixing to fused lects: The process and its outcomes
Authors: Auer Peter , Hakimov Nikolay
Published: May 2020

Objectives:

In this introductory article, we advance a unified framework for analysis and interpretation of transfer of overt linguistic structure in language contact situations. Our goal is to demonstrate that fusion, a process whereby results of bilingual practices become grammaticized and conventionalized (see Auer 1999, 2014), is a gradient phenomenon, which applies to a large spectrum of language contact phenomena. Our additional objective is to situate the contributions to this special issue in the context of this approach.

Design:

The article defines fusion as a central concept underlying the proposed framework, identifies the basic dimensions of fusion and showcases its various outcomes by reviewing extensive contact linguistics literature and the contributions to this special issue.

Data and Analysis:

In our analysis of contact linguistic phenomena, we draw on available linguistic descriptions of pertinent contact varieties and bilingual practices. We examine these phenomena in terms of fusion and in relation to its three basic dimensions.

Findings:

This article shows that fusion, being a gradient multifaceted phenomenon, should be analyzed along the following dimensions: (a) the amount of structure affecting the receiving language, (b) the degree of sedimentation of bilingual patterns, (c) the degree of fusional compartmentalization.

Significance:

The present article identifies and describes manifold outcomes of fusion in terms of three basis dimensions. These dimensions enable one to distinguish fused lects from language mixing and other bilingual phenomena and need therefore be incorporated in future linguistic descriptions and analyses of fused lects.
Recurring ideas: Searching for the roots of right-wing populism in Eastern Europe
Authors: Szelewa Dorota
Published: May 2020

The main sets of ideas that dominated discourses on market-making and democratization in Eastern Europe during the 1990s concerned: first, the superiority of market-led mechanisms of exchange and distribution with individual responsibility and entrepreneurship; and second, the conservative gender order, with women disappearing from the public domain, now being responsible for domestic sphere and the biological reproduction of the nation. Suppressed when these countries were on the path for joining the European Union, the ideas have been now recurring in a new form, representing the basis for the right-wing populist turn in several of the post-communist countries.
Investigation on the mechanical properties of press-hardened boron steel sheets using the conductive heating technique
Authors: Kocar O , Livatyalı H
Published: May 2020

An aluminized 22MnB5 (Boron) steel sheet, used for structural parts in the automotive industry, was subjected to press-hardening followed by austenitizing, both in a conventional furnace and via the conductive (electric resistance) heating method, an innovative technique based on the Joule’s principle for fast heating of the sheet metal. Conductive heating presents a number of advantages over the in-furnace heating method. These include a more efficient use of energy, as well as the requirement of less time and space for heating, thus lowering costs. After press-hardening was performed using both methods, the microstructural and mechanical characterizations of both specimens were examined for optical microscopy, hardness, tensile strength, and high-speed impact tests. The results showed that the press-hardening process transformed the ferritic–pearlitic microstructure in the as-received state into martensite after die quenching and caused a substantial increase in hardness and strength at the expense of ductility and impact toughness. On the other hand, no significant difference was observed in either the microstructure or mechanical properties with respect to the heating method used. The results obtained in the present investigation concur with the findings of current literature.
The role of shopping mission in retail customer segmentation
Authors: Sokol Ondřej , Holý Vladimír
Published: May 2020

In retailing, it is important to understand customer behavior and determine customer value. A useful tool to achieve such goals is the cluster analysis of transaction data. Typically, a customer segmentation is based on the recency, frequency, and monetary value of shopping or the structure of purchased products. We take a different approach and base our segmentation on the shopping mission—reason why a customer visits the shop. Shopping missions include focused purchases of specific product categories and general purchases of various sizes. In an application to a Czech drugstore chain, we show that the proposed segmentation brings unique information about customers and should be used alongside the traditional methods.
Resilience in older people living with dementia – A narrative analysis
Authors: Buggins Sarah-Louise , Clarke Christopher , Wolverson Emma
Published: May 2020

Dominant discourses surrounding dementia tend to focus on narratives of loss and decline. Simultaneously, individuals living with dementia are vulnerable to being dispossessed of personal narratives supportive of identity and well-being. How older people with dementia story their experiences of resilience in this context has not previously been investigated. In response, this qualitative study utilised a narrative approach to understand lived experiences of resilience shared by eight older people living with dementia. Structural analyses indicated that participants’ personal narratives regarding resilience in living with dementia contained distinct and common phases (The Diagnosis, Initial Tasks, 'The High Point', Reflecting on Limitations and Focusing on Today) as well as a variety of dynamic characters. Overarching themes within participants’ narratives included sense of self/identity, being connected to others, sense of agency and having positive attitudes. Participants narrated richer, more active personal stories than those typically represented in dominant social discourses surrounding dementia. As such, their narratives depict lived experiences of resilience that unfolded over time in response to adversity and uncertainty and involved a dialectical process in relation to adjustment and well-being. The findings have important implications for the way resilience in living with dementia is framed and supported.
A model for predicting electromagnetic shielding effectiveness of conductive fiber plain fabric
Authors: Yin Jianjun , Ma Wensuo , Huang Zhaohua , Liu Kui , Leng Zhuang
Published: May 2020

Conductive fiber plain fabric can be used for manufacturing electromagnetic protective products, due to the capacity of electromagnetic shielding effectiveness and deformability. A model was established to predict the shielding effectiveness of conductive fiber plain fabric. The curved surface of fabric can be decomposed into countless ideal planes. The vertical incidence of electromagnetic waves on plain fabric surface can be regarded as the oblique incidence on the ideal plane. The transmission coefficients of transverse electric and transverse magnetic polarized waves were different in each point of fabric surface through the surface equation. The weight factor was supposed as the value of small area at each incident point, and the weighted average of transmission coefficients was deduced. The results showed that, the values of shielding effectiveness increased with the decrease of the pitch of conductive fiber plain fabric and increased with the increase of frequency in the range of 0.1–2 GHz. The trends of theoretical prediction values were consistent with the simulation and experimental values, which proved the rationality of the model.
Mesenchymal Stem Cell–Derived Exosomes Improve Functional Recovery in Rats After Traumatic Brain Injury: A Dose-Response and Therapeutic Window Study
Authors: Zhang Yanlu , Zhang Yi , Chopp Michael , Zhang Zheng Gang , Mahmood Asim , Xiong Ye
Published: May 2020

Background. Mesenchymal stem cell (MSC)-derived exosomes play a critical role in regenerative medicine. Objective. To determine the dose- and time-dependent efficacy of exosomes for treatment of traumatic brain injury (TBI). Methods. Male rats were subjected to a unilateral moderate cortical contusion. In the dose-response study, animals received a single intravenous injection of exosomes (50, 100, 200 µg per rat) or vehicle, with treatment initiated at 1 day after injury. In the therapeutic window study, animals received a single intravenous injection of 100 µg exosomes or vehicle starting at 1, 4, or 7 days after injury. Neurological functional tests were performed weekly after TBI for 5 weeks. Spatial learning was measured on days 31 to 35 after TBI using the Morris water maze test. Results. Compared with the vehicle, regardless of the dose and delay in treatment, exosome treatment significantly improved sensorimotor and cognitive function, reduced hippocampal neuronal cell loss, promoted angiogenesis and neurogenesis, and reduced neuroinflammation. Exosome treatment at 100 µg per rat exhibited a significant therapeutic effect compared with the 50- or 200-µg exosome groups. The time-dependent exosome treatment data demonstrated that exosome treatment starting at 1 day post-TBI provided a significantly greater improvement in functional and histological outcomes than exosome treatments at the other 2 delayed treatments. Conclusions. These results indicate that exosomes have a wide range of effective doses for treatment of TBI with a therapeutic window of at least 7 days postinjury. Exosomes may provide a novel therapeutic intervention in TBI.
Should Interpretative Phenomenological Analysis (IPA) be Used With Focus Groups? Navigating the Bumpy Road of “Iterative Loops,” Idiographic Journeys, and “Phenomenological Bridges”
Authors: Love Beverly , Vetere Arlene , Davis Paul
Published: May 2020

Interpretative phenomenological analysis (IPA) is a qualitative thematic approach developed within psychology underpinned by an idiographic philosophy, thereby focusing on the subjective lived experiences of individuals. However, it has been used in focus groups of which some have been critical because of the difficulties of extrapolating the individual voice which is more embedded within the group dynamics and the added complexity of multiple hermeneutics occurring. Some have adapted IPA for use with focus groups, while others provide scant regard to these philosophical tensions. This raises the question whether IPA should be used with focus group data. To address these concerns, this article will set out a step-by-step guide of how IPA was adapted for use with focus groups involving drug using offenders (including illustrative examples with participants’ quotes). A rationale of why it was important to use both focus groups and an IPA approach will be covered including the value, merits, and challenges this presented. An overview of how participants’ idiographic accounts of their drug use, relapse, and recovery were developed will be provided. This article will conclude with a suggested way forward to satisfy the theoretical tensions and address the question raised in the title.
Effect of multiple warm rolling on microstructure and mechanical properties of 304 stainless steel prepared by aluminothermic reaction
Authors: Abdelrahim H , Mohamed HB , La Peiqing , Fuma Wei , Ma Fuling , Li Zhengning
Published: May 2020

304 stainless steels were prepared by aluminothermic reaction method; first steels are annealed at 1000°C and then rolled at 700°C for different deformation. The microstructures evolution and mechanical properties were distinguished in details. It was found that the steel contains nanocrystalline/submicrocrystalline/microcrystalline austenite and submicrocrystalline ferrite. After rolling to a thickness reduction of 30%, 50%, and 70%, the mechanical properties of the rolled steels were substantially increased, as the deformation increased from 30% to 50%, the tensile strength increased from 650 to 1110 MPa, the yield strength increased from 400 to 665 MPa, and the elongation increased from 8% to 8.5%.
Investigations into the ligand steric and electronic effects of Ru-catalyzed C–H bond arylation directed by 8-aminoquinoline as a bidentate-directing group
Authors: Al Mamari Hamad H. , Al Lawati Yousuf
Published: May 2020

In this study, we report an investigation into the steric (cone angle, θ) and electronic properties of ligands in Ru-catalyzed C–H arylation of aromatic benzamides bearing 8-aminoquinoline as an N,N’-bidentate-directing group. The study employs [RuCl2( p-cymene)]2 as a precatalyst, and a ligand, under study, as a cocatalyst. Various electronically and sterically different monodentate and bidentate phosphine ligands were examined. Other ligands such as phosphites and amines were also tested. The study reveals that while bidentate phosphines, phosphites, and aryl and alkyl amines were found to be ineffective, monodentate triarylphosphines represented by triphenylphosphine were found to be the most effective ligands in the Ru-catalyzed C–H arylation under the conditions specified. In addition, the study reveals that there is a correlation between the steric effects, cone angle (θ) and the reaction efficiency. Thus, for symmetrical phosphine ligands, as the cone angle increases, the yield of the CH arylation product gradually decreased. Moreover, the electronic properties of triarylphosphine ligands influenced the reaction as demonstrated by the decreased ability of electron-poor ligands to promote the reaction. The study also reveals a correlation between the electronic parameter, υCO, of the triarylphosphine ligand and the reaction efficiency. As the carbonyl stretching frequency increases, the reaction yield gradually decreased.

Published: May 2020

Background

Patients are increasingly turning to the internet for health education. Due to the complex pathophysiology, clinic-diagnostic profile, and management spectrum of pituitary tumors, an evaluation of the readability of printed online education materials (POEMs) regarding this entity is warranted.

Objective

(1) To apply established readability assessment tools to internet search results on the topic of pituitary tumors. (2) To identify sources of complexity in order to guide the creation POEMs that are in line with the reading level of the target audience. Methodology: After independent, neutral internet search for the phrase “pituitary tumor,” the first 100 results were subjected to inclusion criteria matching. Analysis was performed using 5 readability assessment tools including Flesch Reading Ease (FRE), Flesch–Kincaid Grade Level (FKGL), Gunning-Fog Score (GFS), Coleman–Liau Index (CLI), and Simple Measure of Gobbledygook (SMOG).

Results

A total of 82 websites met inclusion criteria. All websites were found to be at a higher reading level ( P < .01) than the United States Department of Health and Human Services (USDHHS) recommended sixth-grade level. Mean readability scores were as follows: FRE, 38.79; FKGL, 11.27; GFS, 12.83; CLI, 17.31; SMOG, 12.12. Intergroup comparison between FKGL, GFS, CLI, and SMOG yielded that CLI was significantly higher ( P < .03). No significant differences in readability were noted between academic and other websites.

Conclusion

There is a significant misalignment between the reading level of patients and the readability of pituitary tumor POEMs. This may lead patients to misconceive their diagnoses, management options, and prognosis.

Published: May 2020

Tourist congestion is a significant issue in Jiuzhai Valley World Heritage Site (JVWH). The “demand-driven” approach of alternative transportation system (ATS) has led to the issues related to visitor crowding, visitor safety, and visitor experience quality. JVWH requires a more efficient approach to achieve a suitable tourist distribution while preserving the quality of visitors’ experiences. Accordingly, this study examines descriptive data, which are collected in 2015 regarding visitor use of the ATS in JVWH to spatially model current and future distribution scenarios. Researchers developed four theoretical scenarios by using the computational model which imitate the current ATS system. Imitation results indicate Scenarios 3 and 4, which adjust spot combination and tourist duration are the two most effective methods for balancing tourist distribution, and are, therefore, the most effectively ways to optimize the current ATS system. This research provides a glimpse into potential management strategies for the tourist distribution of JVWH and possibly other parks in China.
Can Text Messages Identify Suicide Risk in Real Time? A Within-Subjects Pilot Examination of Temporally Sensitive Markers of Suicide Risk
Authors: Glenn Jeffrey J. , Nobles Alicia L. , Barnes Laura E. , Teachman Bethany A.
Published: May 2020

Objective tools to assess suicide risk are needed to determine when someone is at imminent risk. In this pilot laboratory investigation, we used a within-subjects design to identify patterns in text messaging (short message service) unique to high-risk periods preceding suicide attempts. Individuals reporting a history of suicide attempt ( N = 33) retrospectively identified past attempts and periods of lower risk (e.g., suicide ideation). Language analysis software scored 189,478 text messages to capture three psychological constructs: self-focus, sentiment, and social engagement. Mixed-effects models tested whether these constructs differed in general (means) and over time (slopes) 2 weeks before a suicide attempt relative to lower-risk periods. Regarding mean differences, no language features uniquely differentiated suicide attempts from other episodes. However, when examining patterns over time, anger increased and positive emotion decreased to a greater extent as participants approached a suicide attempt. Results suggest private electronic communication has the potential to provide real-time digital markers of suicide risk.
Acute Eosinophilic Pneumonia Secondary to Menthol Cigarette Use: A Rare Phenomenon With a Review of Literature
Authors: Harne Prateek Suresh , Rao Suman , Malik Muhammad , Shepherd Zachary
Published: May 2020

Idiopathic acute eosinophilic pneumonia (AEP) is a very rare disease with fewer than 200 cases reported. It has been hypothesized to be a hypersensitivity reaction to an unidentified antigen. The clinical presentation typically involves fever, nonproductive cough, shortness of breath, and bibasilar inspiratory crackles within the first week of antigen exposure. Chest imaging usually reveals bilateral reticular and/or ground-glass opacities. Bronchoalveolar lavage demonstrates >25% eosinophils. Corticosteroids are the mainstay of treatment with good results; however, optimum dose and length of treatment are unclear. We present a case of a 31-year-old male who presented with 2 days of shortness of breath, cough, pleuritic chest pain, fevers, chills, nausea, and poor appetite in the setting of initiation of menthol-flavored cigarettes 2 weeks before presentation. He rapidly progressed to respiratory failure requiring intubation despite broad antibiotic coverage. His course was complicated by severe acute respiratory distress syndrome, circulatory shock, and renal failure. He underwent bronchoalveolar lavage testing that revealed 60% eosinophils. He was treated with steroids and was subsequently extubated and discharged. Eosinophilic counts in the blood peaked on the 10th day of admission to 34%. One week later, the patient was completely free of symptoms. The initiation of menthol cigarette use in this patient is the likely reason for ensuing acute eosinophilic pneumonia, hence adding to the sporadic reports on the role of menthol-flavored cigarettes. This case emphasizes a greater reliance on risk factors, as opposed to eosinophilic markers, for the diagnosis and treatment of acute eosinophilic pneumonia to prevent subsequent respiratory failure and intubation in such patients.

Sustaining and increasing participation in secondary music classes has been a regular topic of discourse within the field of music education. Music researchers and professionals have recently addressed specific issues related to music participation such as access to music classes, policy initiatives, and student interest in the music curriculum. This review of literature is an exploration of student enrollment trends in secondary music classes and a broad examination of the many factors that influence student enrollment decisions. In this review of literature, I frame music participation as a complex issue where multiple factors influence enrollment in secondary music classes. Next, research on the structural, interpersonal, and intrapersonal factors that affect music participation are presented. Finally, I address how music teachers and advocacy leaders might direct their efforts to support and increase music participation.

Tremblay and colleagues asked whether patients receiving either routine anticoagulation or antiplatelet therapy for existing conditions prior to becoming ill with COVID-19 have different outcomes from patients receiving neither therapy. After matching for existing comorbidities, this retrospective observational study finds no evidence for an effect of prediagnosis anticoagulation on mortality.

Apixaban in patients with impaired renal function is supported by limited data. Landmark clinical trials evaluating apixaban in patients with atrial fibrillation and/or acute venous thromboembolism excluded patients with creatinine clearance (CrCl) <25 mL/min. This multicenter, retrospective chart review was conducted to evaluate the safety and effectiveness of apixaban compared with warfarin in patients with CrCl <25 mL/min. Included patients were newly initiated on apixaban or warfarin for at least 45 days with a CrCl <25 mL/min. Patients were evaluated for thrombosis and bleeding outcomes 6 months following initiation of anticoagulation. The primary outcome was the time to first bleeding or thrombosis event. A total of 128 patients met inclusion criteria in the apixaban group and 733 patients in the warfarin group. Time to first bleeding or thrombosis event was significantly different between the apixaban and warfarin groups. Cox proportional hazards model was conducted to control for potential confounding factors for the primary outcome. After controlling for atrial fibrillation and coronary artery bypass grafting, risk of thrombotic and bleeding events was lower in the apixaban group (hazard ratio, 0.47; 95% confidence interval, 0.25-0.92). There was not a statistical difference between time to thrombosis (83 days vs 54 days, P = .648), rate of thrombosis (5.5% vs 10.3%, P = .08), time to bleeding (46 days vs 54 days, P = .886), or rate of bleeding (5.5% vs 10.9%, P = .06). The severity of bleeding and thrombotic events was not different between groups. Apixaban may serve as a reasonable alternative compared with warfarin in patients with severe renal dysfunction.
Creative Chinese Countryside? Township-Village Enterprises as Incubators

Since the turn of the century, creative industries have displayed considerable power in transforming the social and economic landscapes of most global metropolises, including such Chinese mega-cities as Beijing and Shanghai. However, the story of creative industries does not end there. Recent studies have focused on the role of creative sector in the countryside. It has been argued that the creative sector can effectively contribute to diversifying socio-economic development in rural areas by increasing employment, enhancing the quality of life, and promoting social inclusion and community development. With the aim to chart new paths for China’s rural revitalisation and address the country’s ‘three rural issues’ (i.e. agriculture, rural areas and farmers), this paper examines the potentials and challenges to developing the creative sector in rural China. It first reviews the academic debate about expanding the development of creative industries from urban to rural areas. Drawing on the research and classification of creative industries in rural Western Ireland, this study identifies industries characterised by ‘content creation and production’ and ‘creative design services’, which would have potential in rural China. The major impediments to and crucial factors for developing rural creative industries in China are investigated and appraised within the framework of ‘creative people, creative place, and creative support’. After analysing emerging practices in Jiangsu Province, this paper highlights the potential of abandoned industrial complexes in rural parts of China’s coastal regions, which can act as incubators for creative industries. Those former manufacturing plants are the remains of township-village enterprises (TVEs), which constituted part of China’s flagship policy for rural regeneration in the 1980s. Not only do they have special architectural attributes favourable for creative production, but also represent the socio-economic entity of the village collective and are the carriers of cultural meanings and memories. This paper concludes with a set of recommendations for both public and private sectors. It calls for a more proactive stance from governments to promote the creative sector in rural areas and revitalise rural economies and communities through the reuse or regeneration of former TVEs.
Grimy Heritage: Organic Bar Streets in Shanghai and Tokyo
Authors: Farrer James
Published: May 2020

Every city has built environments that are largely regarded as eyesores, for aesthetic, social, or moral reasons. Urban nightlife streets are examples of such ‘grimy heritage’. Not only shabby and disorderly, they harbour forms of commercial sex, drinking cultures, and ephemeral nightlife cultures that many city residents and government officials consider undesirable. Sometimes their built forms are regarded as the enemy of genuine heritage architecture, since they obscure more solid, carefully designed structures around them. However, in many cities, organic nightlife streets—developing in such spaces precisely because they were derelict or poorly regulated—serve important social functions as spaces of creativity and community formation. This paper examines the ways that such ‘grimy heritage’ has developed in Shanghai and Tokyo, using examples from ethnographic research and historical sources, and addressing the question of the contribution of the ‘grimy heritage’ to authentic, urban social life.
Temporal expression patterns of fruit-specific α- EXPANSINS during cell expansion in bell pepper (Capsicum annuum L.)
Authors: Mayorga-Gómez Andrés , Nambeesan Savithri U.
Published: May 2020

Background

Expansins (EXPs) facilitate non-enzymatic cell wall loosening during several phases of plant growth and development including fruit growth, internode expansion, pollen tube growth, leaf and root development, and during abiotic stress responses. In this study, the spatial and temporal expression patterns of C. annuum α- EXPANSIN (CaEXPA) genes were characterized. Additionally, fruit-specific CaEXPA expression was correlated with the rate of cell expansion during bell pepper fruit development.

Results

Spatial expression patterns revealed that CaEXPA13 was up-regulated in vegetative tissues and flowers, with the most abundant expression in mature leaves. Expression of CaEXPA4 was associated with stems and roots. CaEXPA3 was expressed abundantly in flower at anthesis suggesting a role for CaEXPA3 in flower development. Temporal expression analysis revealed that 9 out of the 21 genes were highly expressed during fruit development. Of these, expression of six genes, CaEXPA5, CaEXPA7, CaEXPA12, CaEXPA14 CaEXPA17 and CaEXPA19 were abundant 7 to 21 days after anthesis (DAA), whereas CaEXPA6 was strongly expressed between 14 and 28 DAA. Further, this study revealed that fruit growth and cell expansion occur throughout bell pepper development until ripening, with highest rates of fruit growth and cell expansion occurring between 7 and 14 DAA. The expression of CaEXPA14 and CaEXPA19 positively correlated with the rate of cell expansion, suggesting their role in post-mitotic cell expansion-mediated growth of the bell pepper fruit. In this study, a ripening specific EXP transcript, CaEXPA9 was identified, suggesting its role in cell wall disassembly during ripening.

Conclusions

This is the first genome-wide study of CaEXPA expression during fruit growth and development. Identification of fruit-specific EXPAs suggest their importance in facilitating cell expansion during growth and cell wall loosening during ripening in bell pepper. These EXPA genes could be important targets for future manipulation of fruit size and ripening characteristics.
