Quantification of the influence of rolling stock failures on track deterioration
Authors: Ye Yun-guang , Shi Da-chuan , Poveda-Reyes Sara , Hecht Markus 
Published: October 2020

AbstractThis study focuses on the quantification of the influence of rolling stock failures (RSFs) on railway infrastructure. Taking the wheel flat, a common RSF, as an example, we introduce four quantification indexes to evaluate the influence on the following four deterioration mechanisms: track settlement (TS), track component fatigue (TCF), abrasive wear (AW), and rolling contact fatigue (RCF). Our results indicate that TS, TCF, and AW increase sharply with the increase of the wheel flat length and the vehicle speed, and this increasing trend becomes more acute with the increase of the wheel flat length and the vehicle speed. At low speeds, RCF increases gradually as the wheel flat length increases; at high speeds, it increases sharply at first and then decreases gradually. The influence of the wheel flat on TCF and AW is the most obvious, followed by TS and RCF. These findings can help infrastructure managers (IMs) to better understand infrastructure conditions related to RSFs and can aid them in managing problems with vehicle abnormality in track access charging.

Published: October 2020

Significance Statement
Transformed cultured cell lines are widely used for research on the physiology, pathophysiology, toxicology, and pharmacology of the renal proximal tubule. The lines most appropriate for a given use depend upon the set of expressed genes. The authors have used RNA-sequencing techniques to identify the gene expression profiles of 14 different cell lines, representing six species, plus primary cultures of mouse proximal tubule and compared them with transcriptomes of native mouse kidney proximal tubule. None of the cell lines fully matched transcriptomes of native proximal tubule cells, but all expressed certain gene groups that make them suitable for studying specific cellular processes that occur in the proximal tubule. An online resource allows researchers to identify optimal cell lines to address specific experimental goals.

Background
Cultured cell lines are widely used for research in the physiology, pathophysiology, toxicology, and pharmacology of the renal proximal tubule. The lines that are most appropriate for a given use depend upon the genes expressed. New tools for transcriptomic profiling using RNA sequencing (RNA-Seq) make it possible to catalog expressed genes in each cell line.

Methods
Fourteen different proximal tubule cell lines, representing six species, were grown on permeable supports under conditions specific for the respective lines. RNA-Seq followed standard procedures.

Results
Transcripts expressed in cell lines variably matched transcripts selectively expressed in native proximal tubule. Opossum kidney (OK) cells displayed the highest percentage match (45% of proximal marker genes [TPM threshold =15]), with pig kidney cells (LLC-PK1) close behind (39%). Lower-percentage matches were seen for various human lines, including HK-2 (26%), and lines from rodent kidneys, such as NRK-52E (23%). Nominally, identical OK cells from different sources differed substantially in expression of proximal tubule markers. Mapping cell line transcriptomes to gene sets for various proximal tubule functions (sodium and water transport, protein transport, metabolic functions, endocrine functions) showed that different lines may be optimal for experimentally modeling each function. An online resource (https://esbl.nhlbi.nih.gov/JBrowse/KCT/) has been created to interrogate cell line transcriptome data. Proteomic analysis of NRK-52E cells confirmed low expression of many proximal tubule marker proteins.

Conclusions
No cell line fully matched the transcriptome of native proximal tubule cells. However, some of the lines tested are suitable for the study of particular metabolic and transport processes seen in the proximal tubule.

Authors: Singh Prem , Rathi Harsh , Mishra Anjali 
Published: October 2020

Background: Psychiatric morbidity occurs more frequently in patients with substance abuse than in the general population. Routine evaluation and treatment of psychiatric morbidity can be helpful in improving care of substance abusing population but such data are relatively meager from developing countries.Methods: This study was conducted in the Out-patient facility of the Department of Psychiatry, Veer Chandra Singh Garhwali Government Institute of Medical Science & Research, Srinagar (Uttarakhand), starting from 23 September 2015. One hundred consecutive treatment seeking subjects fulfilling international classification of diseases and related health problems, 10th Revision (ICD-10), criteria for mental and behavioral disorders due to psychoactive substance use were included in the study. All the participants were required to sign an informed consent approved by the institutional ethical committee before being enrolled in the study. All the subjects included in the study were administered a semi-structured Proforma to elicit the clinical and socio-demographic variables. Results: One hundred patients consisting of 95 men (95%) and 05 women (05%) were included. The average age of the sample was 39.68 years (SD=11.97). As for the socio-demographic variables other than age, 87% of the patients were married, 62% patients were living in nuclear families and 66% belonged to the rural areas. 79% patients were educated up to high school and above and only 06% were illiterate. 36 % of the subjects screened positive for psychiatric morbidity. Psychiatric morbidity was significant higher in unmarried people with less education (primary or less) and those living in nuclear families. Conclusions: Psychiatric comorbidity was found in 36% of the study subjects.

Published: October 2020

Purpose: bullying among students with disabilities, especially hearing impairment adolescents is a neglected problem in most Arab countries, including Saudi Arabia.
Objective: This study aimed to investigate the prevalence of cyberbullying and traditional bullying and their relationship to self‐esteem in adolescent students in southern Saudi Arabia.
Methods: Three questionnaires (cyberbullying, traditional bullying, and self‐esteem) were used to assess the studied parameters. They were distributed to 81 students with hearing impairment (10th and 12th grade), (M = 18.64, SD = 1.06).
Main Findings: Findings indicated that 56.4% were exposed to traditional victimization, 52.9% bullied others at school, 44.6% were not exposed to victimization, while 47.1% had not participated. Concerning cyberbullying, 90.5% were not exposed to cyber-victimization, and 94.2% had not participated in cyber-bullying. Males were more exposed to traditional and cyber-victimization than females; besides, they were significantly higher in self-esteem than females. We found a statistically significant correlation between traditional victimization and traditional bully. We also found a statistically significant correlation between self-esteem and both traditional victimization and bully, while no significant correlation between self-esteem and cyber-bully/victims.
Novelty/Originality of this study: Additional studies are needed to compare the traditional bullying and cyberbullying, and its relationship to psychological variables among Saudi children with disability and typically developing peers. Moreover, there is an urgent need for evolving prevention and intervention programs to overcome bullying and its negative effects among individual and society.

Published: October 2020

Purpose: Cloud computing has opened new opportunities in disastrous natural early warning. The scientific community has recognized the significance of the geo-analytic approach in complex decision-making processes for critical situations due to natural events such as coastal erosion and landslides. The paper describes the progress in the development of ITC dissemination systems for the population to promote the preparedness toward the coastal risk.
Methodology: To achieve these goals an information system based on an Open Source Cloud Computing platform following a PaaS (Platform as a Service) and SaaS (Software as a Service) approaches has been used.
Main Findings: The southern coast of Sicily (Italy) and the islands of the archipelagos of Malta are highly exposed to risks coming from the sea. Such coasts are subjected to fast erosion due to natural and anthropic causes which involve the failure of cliffs, the triggering of localized erosions, and the possibility of flooding.
Implications/Applications: The research effort aims to build an interconnected framework through the implementation of smart technology, which involves surveillance, early warning, and reduction of coastal threats, with a specific goal to educate citizens regarding flood hazards, coastal waters, and degradation, cliff collapses and safety steps.
Novelty/Originality of this study: The study expresses a different perspective on cloud computing to prevent the effects of disastrous natural events and to provide indications of areas susceptible to risk.

Authors: Nugraha Michelle Adi , Banglali Nadhia Prili , Abraham Juneman , Ali Moondore Madalina , Andangsari Esther Widhi 
Published: October 2020

Effective learning in the current 4.0 Industrial Revolution era may not happen if a learner is insensitive to two types of social engineering, namely phishing and tailgating. This study aims at investigating the predictors of vulnerability to phishing and tailgating from the psychological perspective. The study was conducted on a sample of Indonesians (125 males, 137 females; Mage = 28 years old, SDage = 8.319 years); considered as the ‘millennial’ age group. Multiple linear regression analyses covering seven predictors of the vulnerabilities, i.e. insufficient knowledge/media literacy, excitement of victory, fear of authority, desire to be helpful, fear of loss, laziness, and appeal to ego, showed that the psychological models predicting vulnerability of experiencing phishing and tailgating were confirmed, with an effect size range between 18.5% to 19%. Media literacy alone was proven to be inadequate in managing/deterring the variables that embrace vulnerability to the two social engineering techniques. The relevance of this study to lifelong learning gravity is discussed throughout this article.

The implementation of virtual choir recordings during distance learning
Authors: Eren Hakki Cengiz , Öztuğ Emine Kıvanç 
Published: October 2020

This study investigates the implementation of virtual choir recordings in a choir class during distance learning. In this particular study, a virtual choir is defined to be a computer-generated sound recording that emulates a realistic choir sound. Students practiced their parts using virtual choir recordings for a period of eight weeks; each student received a recording that excluded his/her own part but included the rest of the parts. After eight weeks of progressive study, students recorded their own voices on top of the virtual choir recordings and submitted them as final projects. Student opinions regarding the virtual choir recordings were obtained through a 12-question survey. In addition, two experts evaluated the final submissions turned in by the students. The data suggests that virtual choir recordings can be helpful to students with efficiency of practice and can provide a suitable audio environment to foster conscious-listening, accurate intonation and perception of pacing. Improvements are suggested to make the virtual choir recordings also more encouraging of musicality, highlighting its future potential not only as a reliable distance education tool, but also as a supplementary device for real-life choir classes, when in-person learning resumes.

Authors: Ramírez Tulio , Torres Cruz Dóris Lilia 
Published: October 2020

El objetivo de esta investigación es comparar los niveles de satisfacción laboral de una muestra de docentes venezolanos de educación primaria y bachillerato del sector oficial, entre los años de 1996 y 2006. Originalidad: Se evidenciaron altos niveles de insatisfacción laboral en los siete factores que cargan la escala aplicada, cuyos resultados se compararon con los obtenidos entre 1996 y 2006 y se observó una profundización del estado de insatisfacción que hace 24 años ya se percibía, sobre todo en los factores extrínsecos al oficio, como remuneraciones, ambiente de trabajo y sus condiciones, así como con los beneficios. Método: se consideró la investigación de enfoque mixto, con la cual se utiliza la estrategia de la escala de satisfacción laboral, administrada de manera on line y construida desde la Teoría Bifactorial elaborada por Herzberg, Mausner y Snyderman en 1959. La conclusión resalta que los factores intrínsecos o motivadores que tienen que ver con la naturaleza misma del trabajo (reconocimiento de la labor, autonomía profesional y trabajo en sí mismo)presentan niveles de satisfacción muy por debajo de los encontrados en los estudios previos referidos.
