Abstract Purpose: Screen-based sedentary behavior (SSB) has been identified as risk factor for mental disorders in most of adolescents. However, there is little literature pertaining to the specific kinds of SSB and its connections with depressive symptoms in most of adolescents. In the present study, we are going to find out the connections between specific types of SSB and depressive symptoms in Chinese adolescents. Methods: A cross-sectional data based on 996 study participants of middle school students in Guangdong Province. SSB was evaluated by distributing the questionnaire of Health Behavior in School-aged Children, while depressive symptoms were evaluated using Chinese version… More >

Abstract To clarify the mechanism of blocking-stressors, psychological contracts, and negative emotions on post-90s employees’ occupational mobility, based on the literature study, a hypothetical model of the relationship was established. Using the blocking-stressor, psychological contract, negative emotion, and occupational mobility scales, 317 post-90s employees were selected to investigate their status. It used correlation analysis and intermediary effect tests to verify the hypothesis model. The results showed that: first, there were significant positive correlations between blocking-stressors, negative emotions, and occupational mobility, while indicating a significant negative correlation with the psychological contract; second, blocking-stressors can directly and significantly predict occupational mobility; and third,… More >

Abstract The current study measures the influence of multitasking behavior and self-efficacy for self-regulated learning (SESRL) on perceptions of academic performance and views in university students during the COVID-19 pandemic in Mexico. 264 university students fulfilled an online questionnaire. It was observed that multitasking behavior negatively influences SESRL (−0.203), while SESRL showed a positive influence of 0.537 on perceptions of academic performance, and multitasking behavior had an influence of −0.097 on the perception of academic performance. Cronbach’s alpha and Average Variance Extracted values were 0.809 and 0.577 (multitasking behavior), 0.819 and 0.626 (SESRL), 0.873 and 0.725 (perceptions of academic performance), respectively.… More >

Abstract The general objective of this article is to show the relationship that exists in the COVID-19 pandemic, the mental health of people and the propensity for work-related accidents in companies. Various results are shown that detail how COVID-19 has generated and is generating mental alterations in people such as post-traumatic stress disorder, PTSD for its acronym in English. Likewise, data are presented that report the influence of mental health as a precursor to workplace accidents in different industries, with which it can be concluded that COVID-19 needs a comprehensive approach in companies to prevent it from negatively impacting workers and… More >

Abstract Therapeutic horseback riding (THR) as an animal-assisted intervention is one of the innovative approaches emerging in the treatment for children with autism spectrum disorder (ASD). The current study was designed to investigate the effects of a 12-week, twice a week THR program on motor skills in sixty-eight children with ASD aged 5–10 years old. All participants selected met the DSM-V criteria for ASD, and a total of fifty-three participants completed the study. A randomized controlled trial design was utilized for the study. Data was collected via a pre-THR test, interim-THR test, and post-THR test to investigate the possible changes in… More >

Abstract Counseling people, particularly those in the military engaged in group living, who are in quarantine during the COVID-19 pandemic is a challenge. Therefore, supporting the people in quarantine who are experiencing psychological and interpersonal problems has become a new challenge in military mental health. This study’s primary concern was how to overcome the problems caused by physical quarantine. The study subject was a virtual counseling network and its operating experience during the quarantine period in Taiwan amidst the global COVID-19 pandemic. For soldiers who mainly live in groups, this study discussed how the virtual counseling network combined with the existing… More >

Abstract The reduction of the hygroscopicity of wood fibers was investigated through a Thermal Treatment (TT) on wood chips performed before the defibering process. The TT and defibering tests were both carried out on a continuous pilot at semi-industrial scale. The thermal treatment study of wood chips, equivalent to a low temperature pyrolysis, was achieved for four conditions (280°C–320°C) for a duration of 10 min. Mass quantification of solids, condensables and gases (FTIR) at the outcome of the thermal treatment allowed to achieve the mass balances for each condition. The increase of the reactor temperature from 280°C to 320°C leads to… More >

Abstract The operating temperature is a critical factor affecting the performances of photovoltaic (PV) modules. In this work, relevant models are proposed for the prediction of this operating temperature using data (ambient temperature and solar irradiance) based on real measurements conducted in the tropical region. For each weather condition (categorized according to irradiance and temperature levels), the temperatures of the PV modules obtained using the proposed approach is compared with the corresponding experimentally measured value. The results show that the proposed models have a smaller Root Mean Squared Error than other models developed in the literature for all weather conditions, which… More >

Abstract Plant-based concretes are produced from plant aggregates and a binder. Plant fibers are mainly composed of saccharides (sugars) and these sugars can decrease the concentration of Ca²⁺ ions in the cement pore solution and delay the formation of hydration products. To improve the interfacial bond between fibers and matrix a chemical treatment is widely used. This study investigates the effect of sodium hydroxide treatment on physical and hygroscopic properties of Typha aggregates. In particular, a 5% sodium hydroxide solution is used to treat these aggregates and their bulk and absolute densities, porosity, water content and water absorption are evaluated accordingly.… More > Graphic Abstract

Abstract This paper is devoted to the analysis of the heat transfer and Navier’s slip effects in a non-Newtonian Jeffrey fluid flowing past a stretching/shrinking sheet. The nanoparticles, namely, Cu and Al₂O₃ are used with a water-based fluid with Prandtl number 6.272. Velocity slip flow is assumed to occur when the characteristic size of the flow system is small or the flow pressure is very small. By using the similarity transformations, the governing nonlinear PDEs are turned into ordinary differential equations (ODE’s). Analytical results are presented and analyzed for various values of physical parameters: Prandtl number, Radiation parameter, stretching/shrinking parameter and… More >
