Changes of hardness and electronic work function of Zr41.2Ti13.8Cu12.5Ni10Be22.5 bulk metallic glass on annealing

The hardness and electronic work function (EWF) of a bulk metallic glass, namely Zr_41.2Ti_13.8Cu_12.5Ni₁₀Be_22.5, have been studied experimentally, with an emphasis on the effect of heat treatments. The glass was annealed at different time and temperatures, and its hardness and EWF measured using the Rockwell indentation technique and a scanning Kelvin probe system, respectively. It is found that the EWF decreases with annealing time and temperature, whereas the hardness increases. This study shows a close relationship between hardness and EWF, indicating that the EWF could be a sensitive parameter for characterising and investigating the mechanical behaviour of BMG at the electronic level.     

上下级沟通对工作应激源-应激的调节作用研究

本研究旨在考察上下级沟通对工作应激源-心理及生理应激的调节作用。研究结果表明:上下级沟通的两个维度及时告知和指导、积极表达对应激源-应激有不稳定的、不强烈的调节作用,既表现为及时告知与指导对工作-家庭冲突与心理应激、对工作负荷-生理应激有缓冲作用(负向作用),也表现为积极表达对工作-家庭冲突-生理应激、及时告知和指导对攻击行为-心理应激有增强作用(正向作用)。     

Crossover between work and home in dyadic partner relationships

This study aimed at providing insight into the processes underlying crossover between "work" and "home" in dyadic partner relationships. Specifically, we examined to what extent husbands' work demands (work load and overtime hours) and psychological health (fatigue and depressive symptoms) "cross over" to their wives' home demands (home load) and psychological health. These associations were investigated among three couple groups, based on wives' working hours (i.e., more than 20 hours per week, from 1 to 20 hours per week, and not engaged in paid work) (253 couples in total). All husbands worked for at least 35 hours a week. Three possible crossover mechanisms were hypothesized: (i) time-based, (ii) strain-based, and (iii) empathy-based crossover. The results partially supported mechanisms (i) and (ii): when husbands reported higher work load (mechanism i) and more psychological health complaints (mechanism ii), their wives experienced higher home load. The results further supported mechanism (iii) that wives' and husbands' psychological health were associated. It is concluded that crossover from husbands to wives may occur through various mechanisms.     

Dynamique des valeurs culturelles au travail en contexte gabonais : influence de la culture nationale et de la culture d’entreprise occidentale

More and more Western organizations settle in Africa and import their corporate culture. This contrasts strongly with local national culture. The present study examines the direct links and the interactive effect of Gabonese culture and Western corporate culture on workplace cultural values. A total of 650 Gabonese employees working in Western organizations answered a questionnaire. The results indicate that Gabonese national culture and Western corporate culture are differentially linked with collectivism at work, given that the former is positively associated whereas the latter is negatively associated. Moreover, an additive effect of both cultures on the distance to power. Thus, the cohabitation between Gabonese national culture and Western corporate culture leads to a mismatch of cultural values at workplace.     

Disruptive pandemic effects on telecommuters: A longitudinal study of work–family balance and well-being during COVID-19

We examined the disruptive influence of COVID-19 pandemic rates in the community on telecommuters' satisfaction with balancing their work and family roles and consequently their well-being. Utilizing event system theory and adaptation theory, we proposed that the rate of increase in proportion of confirmed COVID-19 cases in telecommuters' residential communities would predict a lower rate of increase in their satisfaction with work–family balance over time, thereby indirectly influencing two key aspects of well-being—emotional exhaustion and life satisfaction. Results from latent growth curve modeling using objective community data, as well as survey responses from a three-wave (N = 349) panel study of telecommuters in the United States, indicated that rate of increase in the proportion of confirmed COVID-19 cases in communities was negatively associated with the rate of increase in satisfaction with work–family balance, which translated into decreasing levels of well-being over time. We discuss the theoretical and practical implications of these findings.
