IFRS – Ten Years Later

A decade ago, the near-simultaneous adoption of IFRS in over one hundred countries could fairly have been described as a “brave new world” in financial reporting. Any systems innovation, and especially an innovation of such importance and magnitude, thrusts those involved (companies, users and accountants) into the unknown. There was good reason to expect success, based largely on widespread enthusiasm for international standards and, behind that, recognition of the strong forces of globalization. Nevertheless, there were risks involved and there was limited a priori evidence to guide the decision makers. A decade later, this is still the case. Globalization remains a potent economic and political force, and drives the demand for globalization in accounting. Nevertheless, most political and commercial activity remains local, so adoption of uniform rules does not by itself lead to uniform reporting behavior around the world. For many of the claimed benefits of IFRS adoption to be realized, uniform implementation would have to occur in a wide range of countries, which seems unlikely and requires more than simply creating regulatory enforcement mechanisms. Some evidence of actual outcomes from IFRS adoption has come to light but, as will be argued below, by and large the evidence to date is not very useful. The IASB’s valuation-centric Conceptual Framework leads it to pay little or no heed to the use of accounting information in contracting, despite the lip service recent amendments pay to even the narrower notion of stewardship. So IFRS adoption is an innovation of historical proportions whose worldwide effects remain somewhat uncertain. The essay concludes with comments on the status of China and the US.
Volatilization of trichloroethylene from trees and soil: measurement and scaling approaches.

Trichloroethylene (TCE) volatilization from leaves, trunk, and soil was measured to assess the significance of these pathways from phytoremediation sites at Travis and Fairchild Air Force Bases. Measurements were scaled temporally and spatially to estimate the annual volatilization of TCE at the Travis (0.82 ± 0.51 kg/yr) and Fairchild sites (0.014 ± 0.008 kg/yr). Volatilization was primarily through the leaf (0.34 ± 0.16 kg/yr at Travis and 0.01 ± 0.06 kg/yr at Fairchild) and soil (0.48 ± 0.36 kg/yr at Travis, 0.003 ± 0.002 kg/yr at Fairchild) pathways. The larger volatilization estimate at Travis was expected because of the site’s higher TCE groundwater concentrations. Using groundwater data collected in 2004 and 2009, calculations show that over the 5 year period, 1.7 and 0.015 kg of TCE were removed each year at the Travis and Fairchild sites, respectively. On the basis of the scaled field measurements, volatilization from the leaves and soil may play a significant role in TCE removal at both sites. D...
The Phaeogenes Sensu Stricto of North America

A new species, Phaeogenes gilvilabris , and a new sub-species, P. ophthalmicus americanus , are described. Three species are redescribed and keys to both sexes of the known Nearctic species of the genus Phaeogenes sensu stricto are given.
Crystal Growth Simulations To Establish Physically Relevant Kinetic Parameters from the Empirical Kolmogorov-Johnson-Mehl-Avrami Model

A series of simulations was performed to enable interpretation of the material and physical significance of the parameters defined in the Kolmogorov, Johnson and Mehl, and Avrami (KJMA) rate expression commonly used to describe phase boundary controlled reactions of condensed matter. The parameters k, n, and t0 are shown to be highly correlated, which if unaccounted for seriously challenge mechanistic interpretation. It is demonstrated that rate measurements exhibit an intrinsic uncertainty without precise knowledge of the location and orientation of nucleation with respect to the free volume into which it grows. More significantly, it is demonstrated that the KJMA rate constant k is highly dependent on sample size. However, under the simulated conditions of slow nucleation relative to crystal growth, sample volume and sample anisotropy correction affords a means to eliminate the experimental condition dependence of the KJMA rate constant, k, producing the material-specific parameter, the velocity of the ...

Broad Bandwidth Microwave Measurements of Materials Using Photoconductively-Pulsed Antennas

Accurate measurement of the microwave dielectric properties of materials is an important issue because of the continued advances in high-speed electronic and optoelectronic devices. In packaging conventional electronics, materials such as polymers or ceramics are used as dielectric interlayer spacers. The complex microwave dielectric properties of these surrounding media determine the delay, attenuation, and dispersion of fast electrical signals between devices. Because at present the fastest electrical devices have risetimes of less than 10 picoseconds,1 it is important to be able to measure the properties of dielectric packaging materials to frequencies greater than 100 GHz. Similarly a knowledge of the dielectric properties of polymers and crystalline materials are required in optoelectronics because these materials are being used in high-speed electro-optic modulators and switches. The optical response of these materials is generally very fast so that the ultimate performance of the electro-optic device is determined by the switching time which depends on the capacitative time constant and the microwave group velocity.2
Intracranial Oligodendrogliomas: Imaging Findings in 35 Untreated Cases

The radiographic findings in 35 cases of untreated intracranial oligodendrogliomas were reviewed. The mean age of the patients was 34.6 years, and seizure disorder and headache were the most frequent presenting symptoms. Slightly less than two-thirds of the tumors were histologically pure and almost half were low-grade. Most lesions were cerebral and peripheral in location, and the majority were in the frontal lobes. On CT the tumors were usually hypo- or isodense. Contrast enhancement of tumor occurred in nearly half the cases, and was usually mild and poorly defined. Tumor calcification often occurred, and hemorrhage or cystic formation was not infrequent. Occasionally, calvarial erosion was associated with the tumors because of their peripheral location and slow-growing nature. The lesions were usually sharply demarcated and without edema. MR most frequently revealed hypointense lesions on T1-weighted images and abnormal hyperintensity on T2-weighted scans. In regard to grading or purity of oligodendrogliomas, no significant correlations were found except for a suggestion that higher-grade and mixed tumors tend to enhance more often on CT. The radiographic features of oligodendroglioma are quite characteristic but not pathognomic. A high preoperative suspicion might lead to more appropriate tumor management. MR, although less sensitive in detecting tumor calcification, is superior to CT in defining the tumor extent, which is beneficial for surgical and postsurgical radiotherapy planning.
Approaches to the Diagnosis and Treatment of OCD with Comorbid Tic Disorders

Bidirectional overlap has long been described between obsessive–compulsive disorder (OCD) and tic disorders. Similar features, including underlying neurobiological genesis in frontal-striatal circuitry, familiality, relatively early onset, waxing and waning course, and overlapping phenomenology in repetitive behaviors, suggest different variations of the same disorder. Nevertheless, some differences have been described between OCD and tic disorders: tics begin early in childhood and typically attenuate or remit by late adolescence, whereas OCD tends to onset later and persist, and tic disorders are far more common in males than is the case in OCD. Individuals with OCD plus comorbid tics may represent a specific sub-type of OCD or tic disorders, and possess some important phenomenological differences from those with OCD without tics; for example, tic-related OCD tends to have earlier onset, higher prevalence in males, prominent symmetry, evening-up, counting, and “just-right” phenomenology, when compared with non-tic-related OCD. Recent DSM-5 classification changes now recognize presence of tics as a specifier in diagnosis of OCD; despite a 40 % prevalence rate of comorbid tics in childhood-onset OCD, there is still little data regarding risk factors, validated distinguishing features, course and treatment of this diagnostic group. Prominence of premonitory sensory phenomena, urges or sensations experienced prior to the repetitive behaviors, is no longer thought to distinguish complex motor tics from compulsions. Well established treatments of OCD include cognitive behavioral interventions and pharmacotherapy, specifically the serotonin re-uptake inhibitors (SRIs); although these treatments are also beneficial in tic-related OCD, some studies suggest that at least for pharmacotherapy, SRIs may not be as effective in OCD patients with comorbid tics. Given the frequent overlap of OCD and tics, and the recent designation of tic-related OCD as an OCD specifier, more investigation of the comorbid subtype is clearly needed.
Thwarted belongingness, perceived burdensomeness, and depression among asian americans: A longitudinal study of interpersonal shame as a mediator and perfectionistic family discrepancy as a moderator

This short-term longitudinal study applied Joiner's (2005) Interpersonal-Psychological Theory of Suicide to Asian Americans' experiences with depression. Interpersonal shame (i.e., the experience of inadequacy arising from interpersonal concerns) was hypothesized to mediate the effects of (a) thwarted belongingness and (b) perceived burdensomeness on future depression. Furthermore, the positive associations between (a) thwarted belongingness and (b) perceived burdensomeness on future depression were hypothesized to vary depending on students' experiences with perfectionistic family discrepancy (PFD; their perceived gap between their actual performance and what their parents expect of them). A total of 605 Asian Americans attending predominantly White, Midwestern universities completed 3 online surveys. Conditional process modeling via Hayes's (2013) PROCESS was used to analyze the data. Results demonstrated that (a) thwarted belongingness and (b) perceived burdensomeness contributed to higher interpersonal shame, which influenced students' future depression. Furthermore, the effect of thwarted belongingness on future depression was significantly positive for those with PFD levels greater than the 12th percentile, after taking into account students' initial level of depression. The effect of perceived burdensomeness on future depression was not significant for those with PFD levels greater than the 3.5th percentile. This study identified that students with perfectionistic family discrepancy may be at higher risk for depression while experiencing thwarted belongingness. Overall, findings supported using Joiner's (2005) theory to understand Asian American students' risk for future depression. Future studies may gather data across Asian American students' years in college. Counselors can apply these findings to increase students' awareness about possible risk factors for depression.

CRT-300.03 Role of Transthoracic Echocardiography in the Preoperative Evaluation of Patients with Critical Limb Ischemia Undergoing Surgical Bypass

Peripheral surgical bypass for treatment of critical limb ischemia (CLI) is associated with an increased 30-day cardiovascular event rate (8.8% MACE, 1.5% cardiac arrest, 4.7% myocardial infarction, 1.4% stroke and 2.7% death). The purpose of this study is to evaluate 30-day cardiac outcomes in CLI
Sociocultural and therapeutic perspectives on violence.

The level of violence in American society has become an important political and public health concern. Violence encompasses a wide range of behaviors that involve the exertion of physical or psychological force in order to injure or abuse. It is a complex behavior and, like all behaviors, it occurs in the context of culture. The causes of violence and the various ways in which it becomes manifest are influenced by the prevailing attitudes of society and society's perspective on the aims and legitimacy of particular forms of violence. The article addresses the various theories of aggression and violence, diagnostic issues related to victimization by violence, and therapeutic concerns in treating both victims and perpetrators of violence. Biologic, psychological, and sociocultural perspectives on violence may contribute to conceptual distinctions such as nonhostile aggression versus hostile destructiveness. Violence affects the same racial and cultural groups most likely to have limited access to medical care or who are more resistant to using mental health services. The therapeutic approach to these problems is influenced by the nature of the trauma and the wishes of the patient requiring the commitment and expertise of care providers. Those who act violently need clinicians willing to explore the meaning of the violent act and to respond with understanding rather than with a judgmental attitude.
News sources and the same sex marriage issue: Through the lens of the agenda-setting theory

Using agenda-setting theory, this study explores the effects of news sources on public opinion on the issue of the same-sex marriage over 10 years. It examines immediate substantive salience, immediate affective salience, cumulative substantive salience and cumulative affective salience of the news sources cited in news articles from The New York Times from 2003 to 2013 and compares the coverage to public opinion polls. Four findings merit notice. First, news sources with a clear standpoint had counter effects on public opinion. Second, the salience of news sources is as influential as the affective attribute salience of news sources on public opinion. Official sources had the power to influence public opinion the most. Thirdly, the influence of the media is stronger than the influence of news sources on influencing public opinion. Fourth, LGBTQ sources were the least used sources in the same-sex marriage coverage.
Thyrotoxic Valvulopathy: Case Report and Review of the Literature

We report a 42-year-old female who was admitted for abdominal pain, and also endorsed dyspnea, fatigue and chronic palpitations. Past medical history included asthma, patent ductus arteriosus repaired in childhood and ill-defined thyroid disease. Physical examination revealed blood pressure of 136/88 mm Hg and heart rate of 149 beats per minute. Cardiovascular exam revealed an irregularly irregular rhythm, and pulmonary exam revealed mild expiratory wheezing. Abdomen was tender. Electrocardiogram revealed atrial fibrillation with rapid ventricular response which responded to intravenous diltiazem. Labs revealed TSH of < 0.1 mU/L and free T4 of 2.82 ng/dL, a positive TSH-receptor and thyroid peroxidase antibodies suggesting Grave's thyrotoxicosis. A transthoracic echocardiogram reported an ejection fraction of 55-60%, with mild to moderate mitral regurgitation (MR) and moderate to severe tricuspid regurgitation (TR) and dilated right heart chambers. Pulmonary artery systolic pressure was 52 mm Hg. Transesophageal echocardiogram revealed a myxomatous tricuspid valve with thickening and malcoaptation of the leaflets and moderate to severe TR, mild to moderate MR with mild thickening of the mitral valve leaflets. Abdominal ultrasound revealed wall thickening of the gall bladder concerning for acute cholecystitis. She underwent laparoscopic cholecystectomy and was discharged in stable condition on methimazole for her thyroid disease, and on oral diltiazem for rate control and anticoagulation for atrial fibrillation. Follow-up visit with her cardiologist few months later documented absence of cardiac symptoms, and no murmurs were reported on physical examination. This case underscores the importance of maintaining a high index of suspicion for hyperthyroidism when faced with significant newly diagnosed pulmonary hypertension and TR, as treatment of the thyroid abnormalities can reverse these cardiac findings.

Building on bedrock: William Steel Creighton and the reformation of ant systematics, 1925-1970.

Ideas about the natural world are intertwined with the personalities, practices, and the workplaces of scientists. The relationships between these categories are explored in the life of the taxonomist William Steel Creighton. Creighton studied taxonomy under William Morton Wheeler at Harvard University. He took the rules he learned from Wheeler out of the museum and into the field. In testing the rules against a new situation, Creighton found them wanting. He sought a new set of taxonomic principles, one he eventually found in Ernst Mayr's Systematics and the Origin of Species. Mayr's ideas tied together a number of themes running through Creighton's life: the need for a revised taxonomy, the emphasis on fieldwork, and the search for a new power center for ant taxonomy after Wheeler died. Creighton's adoption of Mayr's ideas as part of his professional identity also had very real implications for his career path: field studies required long and intensive studies, and Creighton would always be a slow worker. His method of taxonomy contrasted sharply not only with Wheeler's but also with two of his younger colleagues, William L. Brown and E. O. Wilson, who took over Wheeler's spot at Harvard in 1950. The disputes between these men over ant taxonomy involved, in addition to questions of technical interest, questions about where and how best to do taxonomy and who could speak withthe most authority. Creighton's story reveals how these questions are interrelated. The story also reveals the importance of Mayr's book for changes occurring in taxonomy in the middle of the twentieth century.
Organizational Culture: An Object-Oriented Framework

This paper proposes a rigorous model for organizational culture. Culture has always been described rather vaguely, often with psychological jargon. It is argued that organizational success depends on the fit between culture and other organizational elements, including information technology. Understanding fit and culture requires a precise specification. Culture itself has many dimensions, each of which may be specified and integrated into a composite contract describing the cultural behavior of the organization. The utility of the proposed model is tested against current organizational research on innovative culture.
Lifetime Psychiatric Diagnoses

Clinicians and researchers often have occasion to classify individuals as ever or as never having had a particular psychiatric disorder. Because of the recurring nature of many disorders, information on an individual patient’s lifetime diagnoses is obviously useful for assessing the present constellation of symptoms and for planning treatment. For research on the etiology of disorders, pragmatic considerations often dictate the use of lifetime diagnoses. The proportion developing a particular psychiatric disorder over a restricted time period is small, even in high risk populations. Consequently, despite conceptual difficulties, potential biases, and the likely inferior quality of information, the cumulative experience of study subjects typically is examined for the occurrence of diagnosable psychiatric disorders.

Intelligent and privacy-preserving medication adherence system

Abstract We present a novel privacy-preserving pillbox system for helping patients improve medication adherence while maintaining privacy and security. In the proposed system, we protect data that needs to be reported to the doctor by ensuring that the data can only be decrypted by the doctor, authorized by a face-to-face key exchange process through out-of-band communication channels. Our system also gives patients fine-grained control over how their information is transmitted and shared, which is a major privacy concern for many patients. Also, for helping physicians to acquire their patients’ data efficiently and safely, we designed a web interface for physicians. In addition to privacy and security issues, current smart pillboxes typically either use open/close sensors, which do not accurately detect whether pills have been removed, or use weight sensors, which are prone to sensing errors if the pillbox is mobile. The proposed system verifies patient pill intake or medication adherence by using a light-based pill detection mechanism that achieves greater than 98% accuracy. Our user study shows that the system is simple to use and alleviates users’ privacy concerns.

The Element of Surprise: A Study of Children’s Book Subscription Boxes in the USA

Through a series of semi-structured interviews with nine owner/managers of children’s book subscription boxes, this article examines the rise of book subscription boxes in the United States, contextualized within the historical precedent for the subscription model in book publishing as seen in circulating libraries, door-to-door subscription sales, and ebook and audiobook subscription services. In light of Amazon’s 2018 founding of their own children’s subscription book box, this article investigates what makes children’s book subscription boxes succeed and why they appeal to readers. Findings suggest that surprise is key to children’s book subscription box appeal and value.
Rollocopter: An Energy-Aware Hybrid Aerial-Ground Mobility for Extreme Terrains

In this work, we design and model a new hybrid aerial-ground mobility system concept for extreme terrains referred to as Rollocopter. The platform would uses common multi-rotor propellers enclosed in a spherical shell to produce the necessary forces to roll on the ground and fly. The proposed platform would be able to achieve (a) multi-modal locomotion (fly and roll) for increased energy efficiency, (b) collision resiliency due to its impact-resistant structure, and (c) high-level of controllability due to three-dimensional actuation. This work focuses on the preliminary design trade-offs, analysis and feasibility assessment of the platform. First, a dynamic model of the robot that considers interaction with the ground is developed. Second, a control architecture for flying and rolling is proposed and evaluated in simulation. Finally, a discussion on the energy efficiency of the flying and rolling mobility modes via leveraging a derived dynamic model of the power consumption is provided.
Effects of fertilization, plant species, and intra-specific diversity on soil carbon and nitrogen in biofuel cropping systems after five growing seasons.

Abstract Land-use change for bioenergy production can release greenhouse gases (GHG) through disturbance of soil carbon (C) pools, but use of native species with extensive root systems as bioenergy crops may help mitigate GHG emissions by enhancing soil C sequestration. Here, we investigated how (1) fertilization, (2) plant species and cultivars, and (3) inter- and intra-specific diversity affect soil C and N accumulation five growing seasons after conversion of an old-field dominated by C3 grasses to a grassland dominated by C4 perennial grasses managed for biofuel production. We manipulated diversity at both the species- and cultivar level, and applied nitrogen (N) at two levels (0 and 67 kg ha−1). Establishment of C4 grass treatments on soils that supported C3 pasture grasses for 36 years enabled us to use the natural abundance C isotope ratio technique to estimate the contribution of new C4 plant-derived C to soil organic matter pools. Our study yielded three main results: 1) annual fertilization did not significantly affect soil C and N concentrations after five growing seasons; 2) increasing inter- and intra-specific diversity did not significantly increase soil C and N concentrations; 3) cultivar- and species identity influenced C4-derived C and total soil C concentrations: big bluestem dominated stands exhibited greater soil C accrual relative to stands dominated by switchgrass and mixed-species treatments. Future research is needed to further assess how big bluestem can aid in the sustainable provisioning of second generation biofuel feedstocks.
Fitness-related benefits: land-based versus aqua-base.

Background It is well documented that individuals participating in land-based aerobic activities receive several fitness-related benefits. Given its virtual weightlessness, thermoregulatory comfort, and ease of movements, aqua-based aerobic activities are commonly perceived as a simpler form of exercise, therefore, lacking the fitness-related benefits equivalent to that of land-based aerobic activities. The purpose of this study was to compare fitness-related benefits between land-based (LAND) versus aqua-based (AQUA) aerobic activity classes within a 15-week period. Methods One hundred and fifty-four volunteers participating in LAND (N.=76) and AQUA (N.=78) exercise groups were required to exercise 2 days per week, 50 minutes per day, for 15 weeks. Pre- and post-fitness assessments obtained were body composition, muscular endurance, muscular strength, cardiorespiratory endurance, and flexibility. Results Mixed ANOVA showed a main effect and interaction for body composition in which, overall, participants decreased more body fat percentage in the land group. A main effect for both muscular strength and muscular endurance was revealed, but no interactions. There were no significant main effects or interactions for neither cardiorespiratory endurance nor flexibility. Conclusions Individuals participating in land-based aerobic activities displayed greater decreases in percent body fat when compared to aqua-based aerobic activities, whereas both land- and aqua-based displayed improvements in muscular strength and muscular endurance. There were no changes in cardiorespiratory endurance and flexibility within both groups.
Insights from new cestodes of the crocodile shark, Pseudocarcharias kamoharai (Lamniformes: Pseudocarchariidae), prompt expansion of Scyphyophyllidum and formal synonymization of seven phyllobothriidean genera – at last!

Three new cestode species are described from the crocodile shark (Pseudocarcharias kamoharai) in Ecuador. All three were examined with light and scanning electron microscopy. The unique combination of morphological features in one of the new species prompted formal investigation of the non-monophyly of Paraorygmatobothrium relative to the morphologically similar genera Doliobothrium, Guidus, Marsupiobothrium, Nandocestus, Orectolobicestus, Ruhnkecestus and Scyphophyllidium. Sequence data generated for part of the 28S rDNA gene were subjected to maximum likelihood (ML) analysis. The resulting tree led to the synonymization of six of these seven genera with Scyphophyllidium, and transfer of their species to the latter genus. With the new species, the number of described members of Scyphophyllidium is now 45. The diagnosis of Scyphophyllidium is revised to accommodate these species. In addition, to expedite future descriptions, eight categories of Scyphophyllidium species are circumscribed, based largely on bothridial features. Scyphophyllidium timvickiorum n. sp. is a category 1 species. Beyond being the smallest category 1 species, it bears, rather than lacks, apical suckers and lacks, rather than bears, strobilar scutes. The two other new species are members of Clistobothrium. Clistobothrium amyae n. sp. differs from its congeners in bothridial shape, elongate cephalic peduncle and tiny size. Clistobothrium gabywalterorum n. sp. differs from the two of its congeners that also possess foliose bothridia in overall size and testis number. Despite their substantial morphological differences, the ML tree indicates they are sister taxa. Both are unique among their congeners in possessing cephalic peduncle spinitriches. The diagnosis of Clistobothrium is revised accordingly.
Inszenierung des Wandels. Funktion von Multimodalität in der Veränderungskommunikation am Beispiel des Imagefilms der Commerzbank 2012/13

Der Beitrag untersucht am Beispiel der Imagekampagne der Commerzbank von 2012/2013, inwieweit der Film als multimodales Medium eine externe Veranderungskommunikation unterstutzen kann. Im Zentrum der Analyse steht der Imagefilm „Der erste Schritt“, in dem die Commerzbank ihre fruheren Geschaftspraktiken kritisch reflektiert, eine Haltungsanderung kommuniziert und die Veranderung hin zu einer verantwortungsvoll handelnden Bank als noch bevorstehenden Weg inszeniert. Mittels einer sozialsemiotischen Filmanalyse untersucht der Beitrag die einzelnen Modi in Bezug auf ihre Funktion innerhalb des im Film dargestellten Change-Prozesses. Die Verfasserinnen zeigen auf, wie es der Bank gelingt, die Haltungsanderung nachvollziehbar und glaubwurdig zu vermitteln, obwohl noch keine sichtbaren Taten den Sinneswandel belegen konnen. Die Autorinnen kommen zum Schluss, dass Multimodalitat im Imagefilm der Commerzbank dazu eingesetzt wird, die idealtypischen Phasen, die in Change-Prozessen durchlaufen werden mussen („Unfreeze“, „Move“ und „Refreeze“), fur die Betrachter zu illustrieren. Damit kann Akzeptanz und Glaubwurdigkeit fur die neue Position der Bank geschaffen werden.
Lupus-associated protein losing enteropathy (LUPLE) complicated by a hypercoagulable state and successfully treated with belimumab.

Protein-losing enteropathy (PLE) is a condition characterized by gut mucosal injury that typically manifests with edema and hypoalbuminemia due to protein loss in the GI tract. We present a rare case of lupus-associated PLE (LUPLE) manifested by profound edema, diarrhea, and thrombotic complications. Through our case report, we discuss the typical clinical presentation, diagnostic studies available, and treatment options for these patients. Our patient’s clinical picture and laboratory markers improved with the initiation of corticosteroids and belimumab, which is a novel treatment regimen for LUPLE. Moreover, our patient was found to have a clinically significant hypercoagulable state that was ultimately attributed to PLE in the setting of systemic lupus erythematosus (SLE). We highlight the increased thrombotic risk in these patients and the subsequent management implications with regard to anticoagulation. Gastroenterologists are likely to be involved in the care of these patients, and may be the first to recognize the constellation of findings in PLE, leading to potentially very effective treatment.
A Comprehensive Analysis on Undergraduate Student Academic Performance using Feature Selection Techniques on Classification Algorithms

Educational Data Mining (EDM) is a growing research field that is applied to analyze and predict student's academic performance and makes intervention approaches to elevate that performance. It is a field of study, which is related to various attributes for analysis student's details such as name, attendance, class test, lab test, spot test, assignment and result in the educational institution. In this study, we mainly focus on calculating the academic performance of undergraduate students with a predictive data mining model by using feature selection techniques with classification algorithms. Feature selection techniques are introduced on the data preprocessing process to find the most inherent and important attributes so that we analyze and evaluate the student's better performance by using classifiers with those selected attributes. For this purpose, we collected 800 student's records of the final year, studying at the undergraduate level of the department of Computer Science and Engineering from North Western University, Khulna. Here, we used and evaluated the performance of four feature selection methods: genetic algorithms, gain ratio, relief, and information gain and five classification algorithms: K-Nearest Neighbor, Naive Bayes, Bagging, Random forest, and J48 Decision Tree. The experimental results depict that Genetic algorithms method provides the best accuracy 91.37% with KNN classifier.
The Effect of Nonspherical Pores and Multiple Scattering on the Ultrasonic Characterization of Porosity

Recently, several papers have dealt with the use of the frequency dependent ultrasonic attenuation to characterize gas porosity in structural solids such as cast aluminum [1–4]. The methods proposed provide an estimate of the volume fraction of pores and the average pore size. The estimate of the volume fraction for laboratory samples has been sufficiently accurate that it encourages thoughts of routine industrial use. In the past year, we have considered several corrections which may be of use in transferring the laboratory methods to industrial samples. Three corrections have been developed. The first is a simple way of accounting for the effects of as-cast surface roughness on the inference of ultrasonic attenuation from phase-sensitive scattering measurements. This topic will be dealt with in the companion paper by Nagy et al. [5]. The second correction deals with the effects of nonspherical pores on the inference of the volume fraction. This effect can be very substantial (e. g., a distribution of microcracks may lead to a large ultrasonic attenuation while having zero volume fraction). Finally, the third correction deals with the effects of multiple scattering. That is, the methods used up until now have relied on the scattering being uncorrelated (which is reasonable for low density gas porosity, i. e., volume fractions <2%). However, at higher volume fractions this assumption begins to breakdown. We propose a strategy based on the Kramers-Kronig relations for including multiple scattering effects. The last two corrections are the subject of this paper.
Deceiving Eavesdroppers by Real Time Persistent Spoofing of Android Users’ Location Coordinates for Privacy Enhancement

Location-based services have exponentially escalated in the past few decades. They appear to be very practical, however, the location of user is constantly being tracked, hoarded, and monitored by tech giants without user knowledge and consent. Google keeps an eye on every motion of its users, irrespective of their security settings. For this study, various Android smartphones were carried through different places for one week without the availability of internet and location services. Later, thorough network traffic analysis revealed that the archived data collected by Google apps and services, contained location data as well. This data is transferred to Google as soon as the internet connection becomes available. Moreover, a detailed performance analysis of existing fake GPS location applications was conducted that revealed a plethora of weaknesses in their performance and none of them aimed to secure users’ real location coordinates. In this paper, we present an interesting solution to obfuscate Android users’ real location coordinates, even in off-line mode, thereby, guaranteeing location privacy.
Assessment of Disparities Associated With a Crisis Standards of Care Resource Allocation Algorithm for Patients in 2 US Hospitals During the COVID-19 Pandemic.

Importance Significant concern has been raised that crisis standards of care policies aimed at guiding resource allocation may be biased against people based on race/ethnicity. Objective To evaluate whether unanticipated disparities by race or ethnicity arise from a single institution’s resource allocation policy. Design, Setting, and Participants This cohort study included adults (aged ≥18 years) who were cared for on a coronavirus disease 2019 (COVID-19) ward or in a monitored unit requiring invasive or noninvasive ventilation or high-flow nasal cannula between May 26 and July 14, 2020, at 2 academic hospitals in Miami, Florida. Exposures Race (ie, White, Black, Asian, multiracial) and ethnicity (ie, non-Hispanic, Hispanic). Main Outcomes and Measures The primary outcome was based on a resource allocation priority score (range, 1-8, with 1 indicating highest and 8 indicating lowest priority) that was assigned daily based on both estimated short-term (using Sequential Organ Failure Assessment score) and longer-term (using comorbidities) mortality. There were 2 coprimary outcomes: maximum and minimum score for each patient over all eligible patient-days. Standard summary statistics were used to describe the cohort, and multivariable Poisson regression was used to identify associations of race and ethnicity with each outcome. Results The cohort consisted of 5613 patient-days of data from 1127 patients (median [interquartile range {IQR}] age, 62.7 [51.7-73.7]; 607 [53.9%] men). Of these, 711 (63.1%) were White patients, 323 (28.7%) were Black patients, 8 (0.7%) were Asian patients, and 31 (2.8%) were multiracial patients; 480 (42.6%) were non-Hispanic patients, and 611 (54.2%) were Hispanic patients. The median (IQR) maximum priority score for the cohort was 3 (1-4); the median (IQR) minimum score was 2 (1-3). After adjustment, there was no association of race with maximum priority score using White patients as the reference group (Black patients: incidence rate ratio [IRR], 1.00; 95% CI, 0.89-1.12; Asian patients: IRR, 0.95; 95% CI. 0.62-1.45; multiracial patients: IRR, 0.93; 95% CI, 0.72-1.19) or of ethnicity using non-Hispanic patients as the reference group (Hispanic patients: IRR, 0.98; 95% CI, 0.88-1.10); similarly, no association was found with minimum score for race, again with White patients as the reference group (Black patients: IRR, 1.01; 95% CI, 0.90-1.14; Asian patients: IRR, 0.96; 95% CI, 0.62-1.49; multiracial patients: IRR, 0.81; 95% CI, 0.61-1.07) or ethnicity, again with non-Hispanic patients as the reference group (Hispanic patients: IRR, 1.00; 95% CI, 0.89-1.13). Conclusions and Relevance In this cohort study of adult patients admitted to a COVID-19 unit at 2 US hospitals, there was no association of race or ethnicity with the priority score underpinning the resource allocation policy. Despite this finding, any policy to guide altered standards of care during a crisis should be monitored to ensure equitable distribution of resources.
Carbohydrate loading and fluid management within enhanced recovery

Abstract Enhanced recovery pathways (ERP) are focused on improving perioperative patient care to reduce postoperative complications and improve outcomes. ERP includes elements of preoperative preparation, fluid management, anesthesia and analgesia, and perioperative nutrition and mobilization. Significant evidence suggests that traditional non-evidence-based perioperative nutritional and fluid management dogmas that prolong fasting and promote fluid overload should be abandoned. Carbohydrate loading has been shown to be safe in non-diabetic patients while also reducing postoperative insulin resistance. Evidence suggest that perioperative fluid overload and restriction should be avoided, and near-zero homeostasis should be the goal of perioperative fluid management. Goal-directed fluid therapy (GDFT) has shown to be safe in most patients and could be beneficial in high-risk patients.
Quasimarket failure

The efficiency of “quasimarkets”—decentralized public goods provision subjected to Tiebout competition—is a staple of public choice conventional wisdom. Yet in the 1990s a countermovement called “neoconsolidationism” began to challenge this wisdom. The neoconsolidationists use the logic of government failure to argue that quasimarkets fail and that jurisdictional consolidation is a superior way to supply public goods and services in metropolitan areas. Public choice scholars have largely ignored the neoconsolidationists’ challenge. This paper brings that challenge to public choice scholars’ attention with the hope of encouraging responses. It also offers some thoughts about the directions such responses might take.
Recognizing and Analyzing Chinese Stone Drugs

Historically, mineral medicines (“stone drugs”) have been widely used in traditional Chinese medicine. In archaeological excavations of Chinese sites in North America containers with remnants of stone drugs are often recovered, but not always recognized and identified. Distinguishing these medicines from soil-derived contaminants can be challenging because of overlapping chemical features, and it is essential that the investigator has access to lists compiled for minerals that have been used for medicinal purposes through the ages. Most stone drugs are of geological origin, but some, such as “dragon’s bone” and charcoal, are usually included among this suite of materials, although they are not minerals. Chemically speaking, stone drugs can be analyzed through a series of common experimental techniques, including spectroscopy (infrared, ultraviolet-visible, atomic absorption, X-ray, plasma), microscopy, spot tests, solubility tests, and examination of sundry colligative properties. Ever-present contamination issues with archaeological samples, however, rarely allow conclusions to be reached that do not include the word “probably.”

Curves That Fill Space

A space-filling curve completely fills up part of space by passing through every point in that part. It does that by changing direction repeatedly. We will only discuss curves that fill up part of the two-dimensional plane, but the concept of a space-filling curve exists for any number of dimensions.
Nursing research related to infants and young children.

There is a timeliness to the publication of an annual review in nursing. This review was focused on nursing research about children under 5 years of age. The review included the nursing identified publications reviewed by Medlars for the five-year period, 1977 to 1981; it was not possible to retrieve all nursing-authored studies in publications if they were not identified as nursing. The review was challenging for several reasons. With the exception of Nursing Research, Research in Nursing and Health, and the Maternal Child Nursing Journal, most nursing publications do not have a standard research reporting style. In addition, there are studies about isolated topics or issues that are hard to fit into a thematic whole.
Natural Language Sales Assistant - A Web-Based Dialog System for Online Sales

This paper describes a web-based dialog system – Natural Language Sales Assistant (NLSA) – that helps users find relevant information about products and services in ecommerce sites. The system leverages technologies in natural language processing and human computer interaction to create a faster and more intuitive way of interacting with websites. By combining traditional AI rulebased technology with taxonomy mapping, the system is able to accommodate both customer and business requirements. Our user studies have demonstrated that, in the context of e-commerce, users preferred the natural language enabled navigation over menu-driven navigation (79% to 21% users). In addition, compared to a menu driven system, the average number of clicks used in the natural language system was reduced by 63.2% and the average time was reduced by 33.3%. The NLSA system is currently deployed by IBM as a live pilot and we are collecting real user feedback. We believe that conversational interfaces like that of NLSA offer the ultimate personalization and can greatly enhance the user experience for websites.
Under New Management: What the Arab Spring Tells Us About Leadership Needs in the Middle East and North Africa

Leadership analysis examines how political heads and managers of public sector organizations can employ styles that will dovetail with the aspirations and energy of their country's inhabitants. Uncovering leadership models capable of channeling growth and productivity in this manner within Arab Middle East and North Africa (MENA) settings is essential to the stability of the region. Turbulent change in a globalizing environment continues to deepen this realization. And the ongoing effects of the Arab Spring highlight the importance of such an undertaking. Clearing a path toward establishing the necessary cultural congruence among administrative processes, tools, solutions, and people is a prerequisite to success that rests on identifying indigenously acceptable approaches to change. Engaging authentic leadership to guide successful achievement of new public management and new public governance goals offers one way to both envision and construct ongoing balance in the future.
Decomposition algorithm for moving a ladder among rectangular obstacles

In this paper we consider the problem of moving a ladder amidst n rectangular obstacles. The problem of moving the ladder between two different placements is solved approximately, by decomposing it into several "local motion planning" problems We give an O(n log n) time algorithm to construct and solve all the local problems. A weighted graph MG, called the motion graph with O(n) vertices and O(n) edges, is constructed from the solutions of the various local sub-problems. The vertices of MG correspond to the placements of the ladder and edges correspond to motions between these placements. The weight on its edges represents the length of the longest ladder moveable between the two placements corresponding to the two end vertices. We give an O(n) algorithm to construct collision-free paths for a given ladder between a pair of free placements by searching the graph MG. Furthermore, using an algorithm like Dijkstra's shortest path algorithm we estimate the length of the longest ladder moveable between any two free placements, in O(n log n) time.
Pyridoxine uptake by rat renal proximal tubular cells

Uptake of [3H]pyridoxine by freshly isolated rat renal proximal tubular cells was temperature dependent and exhibited saturation kinetics, with estimated Kt and Vmax of 1.3 microM and 14 pmol/(10(6) cells.0.5 min), respectively. Pyridoxamine, 4'-deoxypyridoxine and 5'-deoxypyridoxal were as effective as unlabeled pyridoxine in inhibiting tracer uptake, whereas pyridoxamine-5'-phosphate, pyridoxal and 4'-pyridoxic acid had no effect, and other vitameric forms and structural analogs caused intermediate inhibition of cellular vitamin uptake. After 30 min, 88% of accumulated radioactive vitamin B-6 in cell extracts had been metabolized to phosphorylated forms and pyridoxal, which supports metabolic trapping as a mechanism responsible for the cellular accumulation observed. Initial uptake was significantly decreased in the presence of ethionine and ouabain; however, carbonylcyanide-p-trifluoromethoxyphenylhydrazone had no effect. Partial to complete substitution of NH4Cl and LiCl for NaCl had no effect, while partial substitution with RbCl caused significant dose-related inhibition of initial pyridoxine uptake. Amiloride also significantly decreased initial uptake. These data are consistent with a facilitated uptake process for pyridoxine that has substrate specificity and may be modulated by sodium-hydrogen exchange and/or pH gradient effects. Cellular uptake is followed by intracellular metabolic trapping catalyzed by pyridoxal kinase.
