Authors: Zhou Bingping , Li Ye , Tang Yun , Cao Wentao
Published: May 2021

Student cyberloafing is a relatively new educational phenomenon and is getting to be an outstanding issue that educators have to face. It is necessary to find out important factors that aggravate cyberloafing. Using an experience sampling method, this study examined the relationship between academic stressors and cyberloafing. Once a week for five consecutive weeks (T1–T5), 134 undergraduate students assessed the extent of academic stressors and cyberloafing of that week through an electronic questionnaire. Additionally, participants completed a trait self-control scale at Time 2. Results of two-level regression analysis showed that academic stressors were negatively associated with cyberloafing at the within-person level (i.e., week-to-week changes), but not at the between-person level. Furthermore, this relationship pattern was only observed in students with low trait self-control, while those with high trait self-control were less likely to cyberloaf regardless of academic stressors. These findings suggest that cyberloafing can fluctuate over periods, especially for individuals who lack self-control. Future research should consider cyberloafing from a dynamic perspective of individual-context interaction. Several practical implications are also discussed.
Does the Internet Expand the Educational Gap Among Different Social Classes? The Protective Role of Future Orientation
Authors: Chen Jing-Jing , Liu Ming Fei
Published: May 2021

Amid the social background of China where the Internet has penetrated into every corner of an adolescent’s life, we were concerned of the role of Internet usage in influencing the educational gap among social classes. We investigated the mediating role of Internet usage preference for entertainment in the relationship between the family socioeconomic status (SES) and the adolescent’s academic achievement and explored the moderating role of future orientation in the relationship. A total of 614 junior high school students were recruited to complete a questionnaire survey, including questionnaires for family SES, Internet usage preference, and adolescent future orientation. The results showed that (1) the relationship between family SES and academic achievement was mediated by Internet usage preference for entertainment; (2) the indirect effect was moderated by future orientation, such that the negative association between family SES and Internet usage preference for entertainment was only indicated in adolescents with low future orientation; and (3) the direct association between family SES and Internet usage preference for entertainment was moderated by future orientation.
Affective Voice Interaction and Artificial Intelligence: A Research Study on the Acoustic Features of Gender and the Emotional States of the PAD Model

Published: May 2021

New types of artificial intelligence products are gradually transferring to voice interaction modes with the demand for intelligent products expanding from communication to recognizing users' emotions and instantaneous feedback. At present, affective acoustic models are constructed through deep learning and abstracted into a mathematical model, making computers learn from data and equipping them with prediction abilities. Although this method can result in accurate predictions, it has a limitation in that it lacks explanatory capability; there is an urgent need for an empirical study of the connection between acoustic features and psychology as the theoretical basis for the adjustment of model parameters. Accordingly, this study focuses on exploring the differences between seven major “acoustic features” and their physical characteristics during voice interaction with the recognition and expression of “gender” and “emotional states of the pleasure-arousal-dominance (PAD) model.” In this study, 31 females and 31 males aged between 21 and 60 were invited using the stratified random sampling method for the audio recording of different emotions. Subsequently, parameter values of acoustic features were extracted using Praat voice software. Finally, parameter values were analyzed using a Two-way ANOVA, mixed-design analysis in SPSS software. Results show that gender and emotional states of the PAD model vary among seven major acoustic features. Moreover, their difference values and rankings also vary. The research conclusions lay a theoretical foundation for AI emotional voice interaction and solve deep learning's current dilemma in emotional recognition and parameter optimization of the emotional synthesis model due to the lack of explanatory power.
Using First Principles for Deep Learning and Model-Based Control of Soft Robots

Published: May 2021

Model-based optimal control of soft robots may enable compliant, underdamped platforms to operate in a repeatable fashion and effectively accomplish tasks that are otherwise impossible for soft robots. Unfortunately, developing accurate analytical dynamic models for soft robots is time-consuming, difficult, and error-prone. Deep learning presents an alternative modeling approach that only requires a time history of system inputs and system states, which can be easily measured or estimated. However, fully relying on empirical or learned models involves collecting large amounts of representative data from a soft robot in order to model the complex state space–a task which may not be feasible in many situations. Furthermore, the exclusive use of empirical models for model-based control can be dangerous if the model does not generalize well. To address these challenges, we propose a hybrid modeling approach that combines machine learning methods with an existing first-principles model in order to improve overall performance for a sampling-based non-linear model predictive controller. We validate this approach on a soft robot platform and demonstrate that performance improves by 52% on average when employing the combined model.
Three-Dimensional in vitro Models of Healthy and Tumor Brain Microvasculature for Drug and Toxicity Screening
Authors: Piantino Marie , Figarol Agathe , Matsusaki Michiya
Published: May 2021

Tissue vascularization is essential for its oxygenation and the homogenous diffusion of nutrients. Cutting-edge studies are focusing on the vascularization of three-dimensional (3D) in vitro models of human tissues. The reproduction of the brain vasculature is particularly challenging as numerous cell types are involved. Moreover, the blood-brain barrier, which acts as a selective filter between the vascular system and the brain, is a complex structure to replicate. Nevertheless, tremendous advances have been made in recent years, and several works have proposed promising 3D in vitro models of the brain microvasculature. They incorporate cell co-cultures organized in 3D scaffolds, often consisting of components of the native extracellular matrix (ECM), to obtain a micro-environment similar to the in vivo physiological state. These models are particularly useful for studying adverse effects on the healthy brain vasculature. They provide insights into the molecular and cellular events involved in the pathological evolutions of this vasculature, such as those supporting the appearance of brain cancers. Glioblastoma multiform (GBM) is the most common form of brain cancer and one of the most vascularized solid tumors. It is characterized by a high aggressiveness and therapy resistance. Current conventional therapies are unable to prevent the high risk of recurrence of the disease. Most of the new drug candidates fail to pass clinical trials, despite the promising results shown in vitro. The conventional in vitro models are unable to efficiently reproduce the specific features of GBM tumors. Recent studies have indeed suggested a high heterogeneity of the tumor brain vasculature, with the coexistence of intact and leaky regions resulting from the constant remodeling of the ECM by glioma cells. In this review paper, after summarizing the advances in 3D in vitro brain vasculature models, we focus on the latest achievements in vascularized GBM modeling, and the potential applications for both healthy and pathological models as platforms for drug screening and toxicological assays. Particular attention will be paid to discuss the relevance of these models in terms of cell-cell, cell-ECM interactions, vascularization and permeability properties, which are crucial parameters for improving in vitro testing accuracy.

Published: May 2021

Infecting large portions of the global poultry populations, the avian infectious bronchitis virus (IBV) remains a major economic burden in North America. With more than 30 serotypes globally distributed, Arkansas, Connecticut, Delaware, Georgia, and Massachusetts are among the most predominant serotypes in the United States. Even though vaccination is widely used, the high mutation rate exhibited by IBV is continuously triggering the emergence of new viral strains and hindering control and prevention measures. For that reason, targeted strategies based on constantly updated information on the IBV circulation are necessary. Here, we sampled IBV-infected farms from one US state and collected and analyzed 65 genetic sequences coming from three different lineages along with the immunization information of each sampled farm. Phylodynamic analyses showed that IBV dispersal velocity was 12.3 km/year. The majority of IBV infections appeared to have derived from the introduction of the Arkansas DPI serotype, and the Arkansas DPI and Georgia 13 were the predominant serotypes. When analyzed against IBV sequences collected across the United States and deposited in the GenBank database, the most likely viral origin of our sequences was from the states of Alabama, Georgia, and Delaware. Information about vaccination showed that the MILDVAC-MASS+ARK vaccine was applied on 26% of the farms. Using a publicly accessible open-source tool for real-time interactive tracking of pathogen spread and evolution, we analyzed the spatiotemporal spread of IBV and developed an online reporting dashboard. Overall, our work demonstrates how the combination of genetic and spatial information could be used to track the spread and evolution of poultry diseases, providing timely information to the industry. Our results could allow producers and veterinarians to monitor in near-real time the current IBV strain circulating, making it more informative, for example, in vaccination-related decisions.

Development of Composite Indicators of Cyclical Response in Business Surveys
Authors: Kitrar L. A. , Lipkind T. M.
Published: May 2021

The article proposes a new set of composite indicators-predictors in business tendency surveys, which allow identifying early information signals of a cyclical nature in the economic behavior of business agents. The main criterion for the efficiency of such indicators is their sensitivity to a cyclical pattern and changes in the dynamics of statistical referents. Property such as a statistically significant lead in time series or earlier publication allows them to be combined into indicators of early response. The composite Business Activity Indicator (BAI) in the basic sectors of the Russian economy is calculated by the authors for the first time based on the results of regular (monthly and quarterly) business surveys of Rosstat for 1998–2020 with a large-scale coverage of sampling units. In 2020, the number of survey respondents averaged about 20,000 organizations of all sizes. The index reflects the «common» profile in the dynamics of short-term fluctuations of the key parameters of the economic environment, which consists of the «balances of opinions» of respondents to the questions unified for all sectoral surveys and connected with the reference quantitative statistics with cross-correlation coefficients that are statistically significantly different from zero, with a lead at least one quarter. This is its main difference from the well-known indices of economic sentiment and entrepreneurial confidence. The main components of the BAI are the new composite indices of real demand, current output, real employment, total profits and economic situation. They aggregate the relevant «order» statistics for the basic sectors of the national economy, including the main kinds of industrial activities, retail trade, construction, and services.The article provides a methodological substantiation and an extended procedure for identifying the BAI components; their composition is formed for the entire set of retrospective results of business tendency monitoring in Russia. A new Aggregate Economic Vulnerability Indicator with a counterdirectional profile and varying degrees of symmetry of its dynamics relative to the short-term movement of the BAI is being introduced as the main limitation of business activity. Proactive monitoring of emerging vulnerabilities in the business environment is necessary to warn their large-scale accumulation, prevent the risks of economic downturns and ensure the highest possible macroeconomic stability. This integrated approach makes it possible to determine the novelty of the proposed measurements of short-term cyclical fluctuations in economic development.
Trends in Dissolution of First Partnerships in Russia
Authors: Churilova E. V. , Zakharov S. V.
Published: May 2021

The article scrutinizes one of the most acute problems in Russian society – the continued high level of separations among first unions.According to the official statistics data, Russia has consistently held a leading position in terms of divorce rates among European countries.Recent estimates of period total divorce rates suggest that 30–40% of marriages contracted in the 1970-1980s and 50–60% of marriages contracted in the last two decades have a chance of being dissolved.The authors use materials from the panel part of the sample survey «Parents and children, men and women in the family and society» to examine the stability of first unions formed in 1945–2010 – either direct marriage, marriage after cohabitation or cohabitation in partnership cohorts. The results suggest an increase in the proportion of dissolved marriages from 14% in the marital cohorts of 1945–1954 to 30% in marital cohorts of 1980–1989. In these cohorts, «direct» marriages were more stable than marriages, which followed cohabitations. However, it is not so obvious for marriages preceded by cohabitations in the 1990s.Authors conclude that the average duration of a dissolved marriage and the average age of women at the time of the dissolution of the marriage have decreased. Cohabitation remains the least stable form of union with an average duration of 4–5 years. Childless unions break up 2 times more often both among marriages and cohabitations. There has been also a decrease in the average number of children in all types of broken unions with children.Based on results formulated at the final part of the article the authors suggest that the «direct» marriage without prior cohabitation become a less attractive form of union that might positively affect the stability of Russian marriages by reducing the probability of divorce due to such grounds of divorce as incompatibility in characters, views and beliefs, especially in the initial years of joint life.

Antecedents of Knowledge Sharing Behaviour in the Public Sector
Authors: Turyahikayo Everest , Pillay Venitha , Muhenda Mary B.
Published: May 2021

This qualitative study investigated antecedents of knowledge sharing in the public sector. Basing on the theory of planned behaviour and literature review, three antecedents guided the conceptualization of the study namely; employee attitudes, subjective or social norms and perceived behaviour control. Data from the 19 in-depth interviews were thematically analyzed. Findings revealed that employee attitudes towards knowledge sharing in the public sector were both positive and negative. While the theory of planned behaviour focuses on the attitudes of knowledge givers, it emerged that the knowledge seekers’ attitudes mattered as well. Subjective norms were prevalent in meetings, teams, job rotation as well as in the Communities of Practice (CoP). The finding that Communities of Practice were disconnected in terms of knowledge sharing emerged surprising because we had not envisaged it since previous studies have not investigated it. Perceived behaviour control was modified by scanty organizational resources as well as incentives and policies. The study proposes knowledge sharing model for both practitioners and researchers.

Women of reproductive age are suffering from severe hormonal imbalance due to polycystic ovarian syndrome (PCOS).Clinical manifestations of PCOS are diverse including hyperandrogenism, anovulation, infertility and increased risk of metabolic diseases besides psychosocial dysfunction.Additionally, PCOS leads to various other disturbances such as glucose tolerance, cardiovascular disease, dyslipidemia, obesity and metabolic disturbances. Environmental pollutants and Xenobiotic compounds cause changes in gut microbiota, which further affects metabolism causing metabolic disturbances may lead to PCOS.Various metabolic anomalies resulting from interaction with xenobiotic compounds and environmental pollutants contribute for hormonal imbalance. It is an interlinked vicious circle affected by epigenetic and environmental parameters.Epigenetic approach and molecular analysis of genes involved in PCOS is essential for specific treatment.Biochemical markers like assessment of hormones(hyperandrogenism)and ultrasound (in patients above twenty years of age)used as diagnostic parameters for detection of PCOS. Adaptinga healthy lifestyle and minimal exposure to xenobiotic compounds and resetting the disturbed sleep cycle will benefit the patient. Study of molecular markers will help in treating the PCOS in a better manner. This review focuses on important parameters of pathophysiology, which will help in understanding andcreating awarenesson PCOS.

Performance Analysis of Burst Traffic Awareness Based Mobile Sink Routing Technique for Wireless Sensor Networks
Authors: YALÇIN Sercan , ERDEM Ebubekir
Published: May 2021

In wireless sensor networks (WSNs), it is vital to adopt a suitable mobile routing algorithm between sensor nodes and mobile sinks (MSs) for data gathering efficiently. In WSNs, random mobility of the MSs increases the mobile path length in the network when data traffic bursts. Therefore, the focus of this study is to overcome burst traffic in an energy-efficient way using the MSs in the network. In this study, a new burst traffic awareness adaptive mobile routing scheme based on heterogeneous WSNs has been developed. The network area is divided into two cluster groups in the proposed scheme, each with a certain number of clusters. In the network, a MS of each cluster group acts. The MSs gather all data in a single-hop attitude as soon as they arrive at the clusters. In this way, the energy load is distributed evenly among the network. Once a burst data is detected in the routing model, a MS updates its trajectory to the cluster head (CH) where the burst occurs. The performance results validate that the proposed methodology outperforms recent studies based on the network lifetime, average energy consumption, and average mobile path length. Also, the effect of the burst traffic situations on network efficiency is analyzed with simulation.

La emergencia de las nanociencias y las nanotecnologías —una nueva tecnología de amplio espectro—, ofrece oportunidades de desarrollo que requieren de agentes informados y participativos para aprovecharlas como motor para mejorar las condiciones de vida de la población. La divulgación científica cobra un papel relevante en las primeras instancias de la construcción social de los procesos de desarrollo y de formación y participación de los agentes económicos, políticos, sociales y educativos.
Agrupaciones estelares y la estructura del segundo cuadrante galáctico

Los cúmulos estelares y las regiones de formación estelar son considerados importantes objetos para la investigación astrofísica (p.e. Portegies Zwart et al. 2010). Sus características particulares los hacen muy útiles en diversos aspectos. Aproximadamente el 80 % de las estrellas de las regiones de formación estelar se encuentran en cúmulos por lo tanto son ideales para estudiar las primeras etapas de formación y evolución estelar (Lada & Lada 2003; Porras et al. 2003). Están formados por estrellas de aproximadamente la misma edad con un rango de masas estelares amplio lo cual permite derivar sus parámetros fundamentales: tamaños, excesos de color, distancias y edades. Debido a que los cúmulos jóvenes son importantes trazadores de los brazos espirales (Baume et al. 2006; Sung et al. 2013) desempeñan un papel fundamental en la comprensión de la estructura Galáctica. En este trabajo de tesis estudiamos un conjunto de 19 agrupaciones estelares jóvenes ubicadas en el segundo cuadrante Galáctico. Para ello, utilizamos fotometría en el óptico e infrarrojo: SDSS (Ahn et al. 2012) y APASS (Henden et al. 2016), 2MASS (Cutri et al. 2003) y WISE (Cutri & et al. 2013), respectivamente. Teniendo en cuenta que para las regiones de los cúmulos la fotometría en el relevamiento SDSS se encuentra incompleta, hicimos uso de las imágenes FITS y realizamos fotometría de apertura. A su vez, empleamos datos espectroscópicos e información astrom´etrica del satélite Gaia (Lindegren et al. 2018). Las agrupaciones estelares fueron abordadas de manera sistemática, uniforme y homogénea, y seleccionadas a partir de un análisis preliminar realizado sobre 250 cúmulos listados en los catálogos “Milky Way global Survey of Star Clusters” (Kharchenko et al. 2013) y “New infrared star clusters in the Northern and Equatorial Milky Way with 2MASS” Bica et al. (2003b) . El estudio fotométrico, espectro–fotométrico y astrometría detallado nos permitió estimar y calcular sus parámetros fundamentales haciendo uso de tres técnicas de análisis distintas. De la construcción de los diagramas fotométricos multi–banda estimamos los parámetros fundamentales de las 19 agrupaciones estelares. Para 11 de ellas obtuvimos datos espectroscópicos propios del observatorio Gemini, y en conjunto con la espectroscopia recopilada de la bibliografía, realizamos un análisis espectro–fotométrico estableciendo excesos de color y distancias para 17 de los 19 cúmulos estelares. Adicionalmente, para 14 de las agrupaciones estelares derivamos resultados en distancia mediante datos Gaia Data Release 2. A partir de estos resultados investigamos la vinculación de las agrupaciones a la estructura y subestructura de la Vía Láctea redefiniendo su pertenencia a los diferentes brazos espirales, en particular, al denominado Nuevo Brazo más allá del Brazo Exterior introduciendo, a su vez, la presencia de una ramificación entre dos de los brazos principales.
Service Quality of Traditional and Islamic Commercial Banks in Bangladesh
Authors: Rana Shohel , Shakeer Imran Ahmed
Published: May 2021

Purpose: This study aims to know the service quality of the different private commercial banks operating in Bangladesh with the rapid advancement in information technology and provide some guidelines to improve their service qualities.
Methodology: The study used both primary and secondary data to support the objective. Primary data were collected from 240 customers, of whom 120 customers are from traditional private commercial banks and the rest from private Islamic commercial banks operating in Bangladesh using a structured interview schedule, naming SERVQUAL. The study used a convenience sampling method to select respondents. Secondary data were collected from different journals, newspaper articles, books, and various published sources. An independent samples t-test was conducted in the test of the hypothesis.
Findings: This study found a significant difference between the traditional and Islamic commercial banks’ service quality and added that the study area’s customers/clients are not fully satisfied with either traditional private commercial banks or Islamic banks. However, Islamic commercial banks are showing a relatively better picture.
Research Limitations: The Study is limited to Bangladesh’s small marginal market and a small sample size of only 240 respondents, which cannot sufficiently reflect the large population’s actual scenario.
Practical Implications: The Study will help manage the traditional and Islamic commercial banks and policymakers to improve their service quality and improve monitoring efficiency.
Originality/value: The Study extensively identified some factors to improve the traditional and Islamic commercial banks’ service quality for both the banks’ and policymakers’ management. In this regard, the critical factors can be the number of employees and the number of counters, increasing ATM services, ensuring faster services, flexible loan disbursement policy, sufficient floor space, suitable sitting arrangements, and improved online services.
Measurement of Financial Soundness of Life Insurance Companies in Bangladesh: An Empirical Study
Authors: Ahmed Dr. Razu
Published: May 2021

Purpose: The study strives to measure insurance companies’ financial soundness in Bangladesh with reference to private sector life insurance companies listed in the Dhaka Stock Exchange (DSE).
Methods: CARAMELS ratio analysis and multiple discriminate analysis (MDA) have been employed to determine the results using secondary data sources collected from annual reports for ten-year DSE listed companies.
Findings: The study identified a satisfactory capital adequacy ratio (CAR) with a decreasing trend. Reinsurance and actuarial ratio indicate that companies hardly participate in reinsurance. In most cases, all selected companies’ expense ratio during the study period is more than the standard (20 %) of the Insurance Development and Regulatory Authority (IDRA). All the selected insurance companies hold more liquid assets than the necessity. Z scores depicted that all the selected companies are potentially sick position in terms of financial health.
Originality/Value: This study measured the financial soundness of life insurance companies in Bangladesh. No in-depth study was conducted in Bangladesh, particularly on measuring the financial soundness of life insurance companies.
