Scalable and accurate variational Bayes for high-dimensional binary regression models

Modern methods for Bayesian regression beyond the Gaussian response setting are often computationally impractical or inaccurate in high dimensions. In fact, as discussed in recent literature, bypassing such a trade-off is still an open problem even in routine binary regression models, and there is limited theory on the quality of variational approximations in high-dimensional settings. To address this gap, we study the approximation accuracy of routinely-used mean-field variational Bayes solutions in high-dimensional probit regression with Gaussian priors, obtaining novel and practically relevant results on the pathological behaviour of such strategies in uncertainty quantification, point estimation and prediction. Motivated by these results, we further develop a new partially-factorized variational approximation for the posterior distribution of the probit coefficients which leverages a representation with global and local variables but, unlike for classical mean-field assumptions, it avoids a fully factorized approximation, and instead assumes a factorization only for the local variables. We prove that the resulting approximation belongs to a tractable class of unified skew-normal densities that crucially incorporates skewness and, unlike for state-of-the-art mean-field solutions, converges to the exact posterior density as p →∞. To solve the variational optimization problem, we derive a tractable coordinate ascent variational inference algorithm that easily scales to p in the tens of thousands, and provably requires a number of iterations converging to 1 as p →∞. Such findings are also illustrated in extensive empirical studies where our novel solution is shown to improve the approximation accuracy of mean-field variational Bayes for any n and p, with the magnitude of these gains being remarkable in those high-dimensional p > n settings where state-of-the-art methods are computationally impractical.
Challenges in maintaining satisfactory documentation routines and evidence-based diabetes management in nursing homes

Introduction: The increasing prevalence of diabetes worldwide entails an expected rise in the number of older individuals with diabetes needing nursing home placement. Internationally, a consistent lack of adherence to clinical guidelines has been identified in the care of older people. In this study, we therefore investigated whether diabetes management in a sample of nursing homes in Norway and Iceland was in accordance with clinical guideline recommendations. Methods: We used a descriptive cross-sectional study design to assess diabetes management in 12 nursing homes: eight in Norway and four in Iceland. Results: We identified 162 residents with diabetes. The diagnosis of diabetes was available for 100% of the residents in the nursing homes in Iceland and respectively for 81 and 51% of the residents in southwestern and northern Norway. Totally, 3% of the residents with diabetes had a treatment goal for blood glucose regulation (HbA1c) documented in their medical record, 48% had agreed individualized routines for blood glucose measurements and 37% had a HbA1c value measured within the past 6 months available in their medical record. Conclusion: This study has shown a significant discrepancy between diabetes guideline recommendations and clinical diabetes practice related to documenting the diagnosis and type of diabetes, the establishment of individualized treatment goals for HbA1c and the establishment of routines for blood glucose and HbA1c measurements in nursing homes in Norway and Iceland. The results indicate a potential for improvement and a need for more nurses with advanced competence within diabetes in nursing homes.

DIGITAL MORTGAGE BANKING ACCEPTABILITY IN PHILIPPINE UNIVERSAL BANKS: EVIDENCE FROM UTAUT MODEL

The changing consumer behaviour all over the world has resulted in the shift of businesses into becoming client-centric. Clients nowadays want convenience, faster processes, seamless transactions, and instant service. The banking sector is not excused with these changes. In fact, bank clients want the same; bank services at the tip of their fingertips. So how should banks respond to these growing demands of clients? Involving technology in bank operations will ensure faster, more convenient, and more seamless transactions as this allows clients to access bank services anytime and anywhere. This study particularly paid attention to the digitization of mortgage banking using the UTAUT model to better understand its acceptability among its clients. The empirical results found that the determinants of behavioural intention to accept digital mortgage device among mortgage clients were facilitating conditions, performance expectancy and effort expectancy. Furthermore, results revealed that performance expectancy is directly related to internet time, frequency of product purchase using a mobile device and use of mobile banking.
Too central to fail? Terror networks and leadership decapitation

ABSTRACT Leadership decapitation, as a means of hindering the operations and hastening the demise of terrorist organizations, has been the subject of a growing body of research. However, these studies have not examined how an organization’s position in a broader network impacts its ability to weather decapitation. We argue that highly networked organizations possess characteristics that make decapitation less effective. To test this argument, we combine data on leadership decapitation with network data on terrorist organizations and find that well-networked organizations are resilience to leadership decapitation. Our study has implications for our understanding of how terrorist organizations respond to counterterrorism efforts.
The Needs of Caregivers of People with COPD: A Study

The purpose of this research was to replicate a study undertaken with different cohorts of clients and their caregivers in both Australia and the United States of America (USA). The researcher wanted to establish better local information, through the use of a survey, about the needs of informal caregivers who provide physical and emotional care, rehabilitation and supervision of treatments for patients with Chronic Obstructive Pulmonary Disease (COPD), at home. Contemporary feedback about what caregivers perceive as critical to their ability to provide care in the home environment was identified. Health services, particularly professionals such as nurses within those services, need to respond appropriately to these needs.
Compact quasi-elliptic waveguide filters on contoured resonant diaphragms

ABSTRACT We present a new type of waveguide bandpass quasi-elliptic filter whose resonators are implemented by thin transverse resonant diaphragms with an aperture in the form of a rectangular window with two metal L-shaped ridges. It is shown that the amplitude–frequency characteristics of such contoured diaphragms demonstrate the frequencies of parallel and series resonances simultaneously. We also construct equivalent circuits of the third and fifth-order elliptic filters and provide a computer simulation of the diaphragms satisfying the amplitude–frequency characteristics of each resonator. It is shown that for waveguide elliptic filters, some resonators can be located on one resonant diaphragm, which further reduces the length of the filter. The synthesis results of compact quasi-elliptic filters for WR137 rectangular waveguide with the central frequency of 6.5 GHz and bandwidth of 7.5% are presented. The total length of the filters is 34 mm for third order and 64 mm for fifth order, respectively.
High‐quality tweet generation for online behavior security management based on semantics measurement

Behavior security management refers to monitoring and guiding the user's opinions in online social networks to reduce their harmful influence to social public security. Pushing designed tweets with specific contains to them is one of the promising ways to solve this problem. In this paper, we developed a new method for high‐quality supervision tweet generation, which not only considers the semantics of the tweets but also includes the supervision requirement of different aspects. Firstly, we collect millions of tweets of six typical events. Following, we construct a sentiment lexicon suitable for online behavior analysis, and we also construct a lexicon for tweet preprocessing and emotional score calculation. Secondly, to include the semantics during sentence similarity calculation, we employ the tweets collected to train the word2vec model and employ the sum of the word vectors in specific sentences to form the sentence vector. Finally, we employ the TextRank to generate the supervision tweet. Experimental results based on data collected showed that the proposed methods outperform other related traditional methods, which can be used for effective social security management.
Comparison of Leadership Styles of University Students in Terms of their Demographic Characteristics

The primary purpose of this study was to determine the Kurt Lewin’s leadership styles of college students and also to determine whether their leadership styles differ with their demographic characteristics or not. The participants were 384 students sampled from the total student population of Ondokuz Mayis University in Turkey, based on Cochran’s sample size determination formula for categorical data collection instruments. Overall, 49.2% of the respondents were democratic leaders 34.9% were autocratic, and 15.9% were laissez-faire style leaders. The Chi-square test, conducted on the variables of leadership style and demographic characteristics of students, revealed significant effects of gender and parents' place of residence but was independent of other factors. Female respondents and respondents coming mostly from rural and suburban areas tended to be more democratic leaders in comparison with male respondents and respondents coming from more densely populated or metropolitan areas. The study suggests that similar researches should be conducted to determine the influence of leadership style on the performance of workers employed in different businesses in Turkey.

How to Establish Talented Employees in Slovak Companies

In this paper, we examine HRM processes and procedures in Slovak companies and their impact on the development and retention of talented individuals. The paper presents expert opinions on talented employees and talent management with the emphasis on talent pools. These are compared from several points of views and critical evaluating judgements are adopted. We find that talented employees, in comparison to other employees, tend to consider a better job offer from another company as a reason to change their employer. Moreover, they understand the feeling of recognition and being valued as an important stabilizer. These axioms are linked together with various managers' opinions on how to attract and retain employees with required potential and performance. The theoretical basis is supported by a survey undertaken in 2017 in 381 Slovak companies which were selected on the basis of their international scope and long-term performance. The survey respondents were human resources managers and/ or personnel responsible for HRM. The Delphi method was used to question experts about the importance of supporting talented employees in enterprises.
Teacher Effectiveness by Enhancing the Self-Concept and Interpersonal Relations: Strategies and Techniques

The connection between teacher effectiveness, the self-concept and interpersonal relations is seldom reflected in research literature today. A search of selected databases reveals that there was a plethora of research and writings addressing this topic during the 60s and 70s. The purpose of this study is to report the results of an examination of forty-one publications predominantly from the 1970s which addressed techniques for enhancing the personal and interpersonal relations of preservice teachers. This study will examine this literature for answers to the following questions: What is the impact of teacher education programs on teacher attitudes toward self and others? What do teachers need in order to develop as fully functioning persons? What are the structured group experiences known to impact the self-concept and interpersonal relations?
Collaborative approach in developing regulations for mobile money in Sri Lanka

Mobile money brought bank‐like facilities through low‐cost operations and extensive agent networks to unbanked communities. Regulatory responses and support are essential, requiring significant changes to current regulatory practices. Due to their limited technical knowledge and financial technology resources, regulators worked with industry to overcome these challenges. Such collaborations are scarce. This study proposes a model for mobile money collaborative regulatory development. Actual practices were mapped with negotiated rulemaking theory to derive variations and extensions to the original theory. Regulators appointed a discussion committee with broader representation for objective decisions. Throughout the negotiation process, the central bank maintained close control; participants are motivated to compromise their interests to achieve joint gains. Findings reveal that collaboration gave participants the necessary knowledge and information to develop effective regulation. The central bank composed the executable rule through collaboration. Subsequent revisions are also key to regulatory development. These revisions were developed with stakeholder involvement as suggestions and comments. Mobility regulation also observes collaborative testing and benchmarking. Specialized subcommittees will further improve the negotiation process.
Immunological Responses in Female Rats Model with Anemia Treated with Snake Fruit Seed Flour Extract

Natural substances become popular for alternative treatment of human diseases including anemia. A recent study has reported that administration of snake fruit seed flour (SSF) is able to increase hemoglobin level in rat model with anemia but it needs higher amount of SSF. In addition, SSF contains 3.71% protein/100g that potentially results in hypersensitivity. The aim of this study was to evaluate the side effects of SSF extract on leucocytes number and its differential account (granulocytes, lymphocytes, and monocytes) in rat model with anemia. We used 14 female rats model with anemia, aged 8-10 weeks, and had ± 200 g body weight (BW). After rats model with iron deficiency anemia (IDA) has been established, female rats were randomly divided into 2 groups: control (C) group only received a low iron diet, and treatment (T) group received a low iron diet and 1.75g/kg BW/day SSF extract for 14 days. Leucocytes number was measured using a veterinary haematology analyzer. Collected data were analyzed using the independent T-test with p value <0.05. Female rats in the C group had the mean leucocytes number higher than the T group, but not statistically different (p=0.073). From differential count, greater numbers of granulocytes and monocytes were observed in the C group, compared to the T group (p=0.301;p=0.34). In contrast to granulocyte and monocytes number, the mean lymphocytes number in the C group were statistically different than the T group (p=0.046). Overall, administration of SSF extract was able to decrease leucocytes number and differential count. Administration of 0.175g/100g BW/day SSF extract does not increase immunological responses in female rats model with anemia.
The Need to Increase Physical Activity During the Elementary and Middle School Years

Despite evidence linking physical activity during childhood to later health outcomes, physical education programs in elementary and middle schools have slowly been eroded during the past two decades. Many educators and parents believe that the time and money spent on physical activity during school hours might be better spent on academic pursuits. This Brief provides a summary of three relevant longitudinal studies, and a recent study by Tremblay, Inman, and Willms (in press) which examined the relationships among children’s self-esteem, levels of physical activity, body-mass index, and academic achievement. The data were collected from the full population of grade 6 students in New Brunswick in 1996, as part of the Elementary School Climate Study. The findings indicate that the concern that physical activity has a deleterious effect on achievement is not well founded. Moreover, increased physical activity has important positive effects on self-esteem and physical health, which in the longer term may contribute to academic success. ▸ The leading cause of death in Canada is heart disease. Three of the most important modifiable risk factors for heart disease are poor nutrition, smoking, and a lack of physical activity. The evidence linking physical activity and health is stronger for adults than for children; however, the likelihood of being active as an adult is influenced by habits established during childhood.
Modeling route choice behavior using the concepts of regret and rejoice

Although the classic multinomial logit model has been widely applied in a variety of choice contexts, its strict IIA property makes it difficult to apply to route choice behavior because alternative routes overlap. Several models have therefore been proposed to resolve the issue. Contributing to the vast literature on route choice modeling, this paper explores reference dependent effects of route overlap based on the concepts of regret and rejoice. Route choice models based on these concepts that include the effects of route overlap are estimated. The models are estimated on route choice data extracted from GPS-data, collected in Rotterdam, the Netherlands. Results show evidence of reference-dependent behavior in the sense that the effects of route overlap differ between regret and rejoice. These effects are significantly affected by travel distance.
Topological insulator overlayer to enhance the sensitivity and detection limit of surface plasmon resonance sensor

Abstract Surface plasmon resonance (SPR) sensors have been applied in a wide range of applications for real-time and label-free detection. In this article, by covering the topological insulators nanosheets on the surface of the noble metal (Au), the sensitivity of the SPR sensor is greatly enhanced because of the strong interaction of light with Au–bismuth selenide (Bi2Se3) heterostructure. It is shown that the sensitivity of proposed SPR sensors depends on the concentration of Bi2Se3 solution or the thickness of the coated Bi2Se3 film. The optimised sensitivity (2929.1 nm/RIU) and figure of merit (33.45 RIU−1) have been obtained after three times drop-casting, and the enhancement sensitivity of proposed sensors is up to 51.97% compared to the traditional Au–SPR sensors. Meanwhile, the reflection spectrum is simulated by using the method of effective refractive index, and the reason for the increase of sensitivity is analysed theoretically. For researching the application of modified SPR sensor, heavy metal detection is employed to detect in the last part. Our proposed SPR sensors have potential applications in heavy metal detections and biosensing.
