Part-time employment and worker health in the United States

A growing body of research has highlighted the consequences of part-time employment for workers’ health and well-being. However, these studies have yielded inconsistent results and relied on cross-sectional data. In addition, relatively little empirical research has explored whether the effect of working part-time on health varies by gender, particularly in the United States. Using longitudinal data from three waves of the General Social Survey panel (2010–2012–2014), our study examined the association between part-time employment and perceived health among U.S employees, and whether this association varied by gender. The results showed that part-time workers were less likely to report poor self-rated health than full-time workers, especially among males. The pattern of results was consistent across empirical approaches—including generalized estimating equations and random effects models, with an extensive set of covariates. Taken together, these findings suggest that for U.S. employees, working part-time appears to be beneficial or at least not detrimental to perceived health, which warrants further investigation.     

Heterogeneity in treatment effects across diverse populations

Differences in patient characteristics, including age, sex, and race influence the safety and effectiveness of drugs, biologic products, and medical devices. Here we provide a summary of the topics discussed during the opening panel at the 2018 Johns Hopkins Center for Excellence in Regulatory Science and Innovation symposium on Assessing and Communicating Heterogeneity of Treatment Effects for Patient Subpopulations: Challenges and Opportunities. The goal of this session was to provide a brief overview of FDA-regulated therapeutics, including drugs, biologics and medical devices, and some of the major sources of heterogeneity of treatment effects (HTE) related to patient demographics, such as age, sex and race. The panel discussed the US Food and Drug Administration's role in reviewing and regulating drugs, devices, and biologic products and the challenges associated with ensuring that diverse patient populations benefit from these therapeutics. Ultimately, ensuring diverse demographic inclusion in clinical trials, and designing basic and clinical research studies to account for the intended patient population's age, sex, race, and genetic factors among other characteristics, will lead to better, safer therapies for diverse patient populations.     

基于高校学生工作视角下微信自我呈现的性别研究

自我呈现是指策略性的表现自我以寻求社会认同的方式，主要形式包括微信个人信息和朋友圈的自我呈现。作为高校学生工作管理者，通过关注和解读学生的微信信息，可获取一手的学生动态，及时掌握学生的情况，进行深入细致的研判。本文通过抽样调查发现：大学生群体中，男同学自我呈现的学业和社会导向较高，女同学自我呈现的情感和生活导向较高；女同学整体自我呈现程度高于男同学。     

Does the Role of Student Factors with Adolescent Substance Use Vary by Geography?

This study assesses the association of 12th-grade student factors (e.g., grades, classroom misbehaviors) with substance use (i.e., binge drinking, cigarette smoking, marijuana) across large, medium-sized, and nonmetropolitan areas. Based on a sample of 2,189 students from the 2013 Monitoring the Future data set, logistic regression analyses showed that poor student academic and behavioral factors were associated with higher substance use after controlling for gender, race, and socioeconomic status. Interaction analyses further showed no significant differences in the influence of student factors on substance use across locales. Results suggest that prevention efforts against substance use should target student factors regardless of area of residency.

Gender differences in risk behavior and the link to household effects and individual wealth

This study examined the differences in risk behavior between men and women using a household survey that captured the risk preferences of two members in a household and recorded wealth at the individual level instead of the usual approach of representing wealth at the household level. After controlling for commonly used explanatory variables, such as gender, education, age, and wealth, household fixed effects explain about 15% of the variation in risk behavior. This highlights the magnitude of household effects in shaping one’s risk behavior. In general, females in the study area are more risk averse than males based on a risk game with real payout. The gender differences disappear when focusing on only the top land owners. However, even in those cases, females consider themselves more risk averse, supporting results from previous studies that link culture and societal norms to the gender differences in risk behavior.     

Rebuilding Relationships in a Transgender Family: The Stories of Parents of Japanese Transgender Children

This study considers the process by which parents accept their transgender children through an analysis of the stories of parents in Japan. The study also considers how the gender identity of parents is affected by their child and the discourses related to queer identities. The mothers were strongly motivated to understand their child and reconstructed the image and life stories of the child. Through these processes, the mothers came to reconsider their own gender identities in queer ways. In contrast, the fathers had a lack of motivation to understand their child, and their masculinity was not significantly influenced by deessentialism.     

Vicarious ostracism and control in young children

After observing ostracism or social exclusion, older children, adolescents and adults report decreased satisfaction of the need for control. Attempting to regain control can motivate aggression in ostracized adults. Research has shown that the onset of ostracism’s harmful effects on children’s behavior is at preschool age. We investigated whether preschoolers would exert more control after witnessing ostracism. A sample of 53 children (Mage = 5 years, 5 months) first watched priming videos either showing ostracism or not. Subsequently, they participated in two ball games. In both of the games (order counterbalanced), children could control the flow of a ball’s motion, either live between two people (i.e., social control) or between two bars on a laptop screen (i.e., non‐social control). Overall, children understood social exclusion when it was displayed in the videos. We found an effect of observed ostracism only on social control. Four‐ to five‐year‐old boys who witnessed ostracism stopped a ball game between two persons longer than boys who did not witness ostracism. Our results suggest that observing social exclusion elevates young boys’ need for control over a social situation. Girls showed a different pattern but their responses did not differ significantly between ostracism and non‐ostracism conditions.
