Why social status matters for understanding the interrelationships between testosterone,economic risk‐taking,and gender

We conduct an extensive review of the literature on testosterone and economic risk‐taking behavior. In sum, there is evidence of a positive association between testosterone and economic risk taking, although it is unlikely to be a strong association given the abundance of null results. However, we argue that the existing literature may overstate the causal effects of testosterone on economic risk taking (or even report a spurious correlation) because this research has not considered the potentially confounding role of social status. Status could concurrently influence both testosterone and economic risk taking, given that testosterone is a social hormone with a reciprocal relationship with social status, and social status has been found to drive risk‐taking behavior. We also argue against using findings from this literature to make gender essentialist claims, primarily because social phenomena influence the size—and existence—of gender differences in economic risk‐taking behavior. We conclude with suggestions for future research.     

A Method to Handle Zero Counts in the Multinomial Model

In the context of an objective Bayesian approach to the multinomial model, Dirichlet(a, …, a) priors with a < 1 have previously been shown to be inadequate in the presence of zero counts, suggesting that the uniform prior (a = 1) is the preferred candidate. In the presence of many zero counts, however, this prior may not be satisfactory either. A model selection approach is proposed, allowing for the possibility of zero parameters corresponding to zero count categories. This approach results in a posterior mixture of Dirichlet distributions and marginal mixtures of beta distributions, which seem to avoid the problems that potentially result from the various proposed Dirichlet priors, in particular in the context of extreme data with zero counts.     

Cash Transfers and Children's Education and Labour among Malawi's Poor

This article examines the impact on children's education and labour of monthly cash grants targeted on ultra‐poor households and designed to reduce poverty and enable families to invest in human development. It conducts a randomised community trial, with baseline and endline surveys of intervention and control households; verifies school enrolment; and completes key‐informant interviews and focus‐group discussions. Compared with non‐beneficiaries, intervention children experienced a 5 percentage point difference in enrolment, higher educational expenditures, fewer absences, and a 10 percentage point decrease in labour outside the home. Qualitative data confirm the quantitative findings. Transfers to poor households had a positive impact. However, the Malawian educational system needs to be improved for short‐term impacts to lead to long‐term development in human capital.     

American High School Students’ Perceptions of Determinants of Life Satisfaction

Life satisfaction can be assessed either globally or with regard to satisfaction with specific domains of life. The latter multidimensional approach presumes science has delineated with confidence the specific domains most relevant to evaluating whether the criteria for a good life have been met. This paper shares results of a qualitative study of the perceived determinants of life satisfaction among 30 high school students who were diverse in terms of mental health; 6–10 participants were classified as complete mental health, vulnerable, symptomatic but content, or troubled at two time points separated by a year. Thematic analyses of transcribed individual interviews suggested eight themes that capture the domains of life adolescents perceive influence their happiness. These themes are compared and contrasted to domains included in existing multi-dimensional measures of youth life satisfaction. The factors likely to be particularly salient to students with different levels of mental health are noted.

     

Warum und wodurch Coaching wirkt

The contribution reviews the state oft the art of the research on general success factors in the coaching process. Research in the field of psychotherapy on basic variables of client centered counseling and general therapeutic change mechanisms set an example. Results of first studies on these and modified factors show that the coaching outcome depends on observed esteem and emotional support by the coach, resource activation and support of transfer into practice. Process analysis of nonverbal interactions between coach and client demonstrate that goal attainment influence goal attainment. Finally, the paper focuses on limitations, of the studies, scientific and practical conclusions as well as future perspectives.     

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.     

Humility,Forgiveness, and Emerging Adult Female Romantic Relationships

Among a sample of emerging adult females (N = 152) we empirically examined the role of humility and forgiveness in romantic relationships. We specifically tested a model linking perceived humility to relationship satisfaction with self‐forgiveness and partner‐forgiveness. Participants in a romantic relationship completed measures of self‐reported humility, self‐forgiveness, partner‐forgiveness, and relationship satisfaction. Serial mediation analyses were conducted using path analysis to test the following sequence, humility self‐forgiveness partner‐forgiveness relationship satisfaction. Findings indicate that humility was related to relationship satisfaction via a serially mediated path of self‐forgiveness and partner‐forgiveness, which was not reducible to impression management. We consider implications for research and clinical practice.     

Education,Skills, and Wage Gaps in Canada and the United States

We analyse data from the Programme for the International Assessment of Adult Competencies to reveal that immigrants in Canada and the United States make over $200 less per month than native‐born workers. In the United States, immigrants disproportionately work in low‐wage occupations, leading to large mean national differences between immigrants and native workers. The wage differential disappears after accounting for education and cognitive skills, indicating policies must focus on reducing education and skill gaps in the United States. In Canada, an immigrant wage gap persists in nearly all occupational fields, suggesting that the better skilled and educated immigrants in Canada are not receiving the same wage premium as native workers. We close with implications for policy and future research.
