This study discusses the results of a survey of 1,800 articles published in American medical journals from 1985--1996. The study finds 9% of these articles reported research that uses only male subjects to examine medical conditions that affect both sexes; the ratio of research on female to male conditions among these articles was greater than 5:1; but 76.5% of the articles reported research that includes both male and female subjects. The study also discusses evidence that sex biases against women (and men) are decreasing. This study also offers some possible psychological, institutional, medical, and economic explanations of the sex biases in medical research published in American journals, and discusses some policy implications of sex biases in medical research. The study concludes by urging others to conduct more empirical research on sex biases in medical research.  相似文献

This study implemented a multiple‐phase, contrast, single‐case research design to examine the effectiveness of the 4 core dialectical behavior therapy skills group modules in reducing emotion dysregulation. Three participants completed four 6‐week skills modules over 9 months. Examination of calculated estimates of treatment effect indicated that 2 out of the 3 participants experienced meaningful changes in their degree of emotion dysregulation over the course of treatment. Implications for counseling practice are discussed.  相似文献

This study focused on the extent to which religion, spirituality, and political beliefs predicted counseling students' perceptions of psychological safety and appreciation of differences in their programs. The authors used hierarchical regression models to analyze data from 264 students from 4 different institutions. Results indicated that student age, political conservatism, extrinsic religiosity, and intrinsic spirituality were significant predictors of perceived psychological safety and appreciation of differences. The authors discuss implications of these findings.  相似文献

This research uses a combination of text mining, co-word analysis, and social network analysis (SNA) to review 132 international sales and sales management (ISSM) articles published between 1980 and 2017. The study provides a unique view of the past and future of ISSM research and provides three principal contributions. First, from a social network–analytic perspective, it offers a unique examination of the ways ISSM research topics are interconnected, as reflected by keyword network structure. Second, by conducting SNA across two periods (1980–1999 and 2000–2017) and examining the changes in network centrality measures, the study offers initial insights into the evolving nature of the ISSM literature. Third, the study reports keyword network disconnections (i.e., structural holes) to propose a fruitful agenda for future ISSM research. Taken together, this research offers a current perspective of the ISSM research domain's evolving nature.  相似文献
