This article expands understanding of gender and advancement in academic science by going into a new dimension of inquiry: Focusing on women associate professors in computing, it assesses the relationship between perceived chances for promotion to full professor and indicators of entrepreneurship, as part of key sets of individual and departmental independent variables that are also addressed. Data from a national survey of women in academic computing indicate that time spent in entrepreneurial activity does not predict excellent/good (compared to fair/poor) chances for promotion perceived by these women faculty, nor does the quantity/quality of entrepreneurial activity that they report for their home units. Departmental reward structures reported as favoring entrepreneurial activity negatively predict perceived chances for promotion. Other key individual and departmental characteristics also predict chances for promotion: faculty members’ age, collaboration, family characteristics, departmental climate, and US (compared to Canadian) location. Findings from interviews with a small subset of respondents to the survey illuminate the survey findings on the role of entrepreneurial factors in perceived chances for advancement. 相似文献

This study investigated whether maternal employment would be associated with teenage sexual attitudes and behaviors likely to increase the probability of teenage pregnancy. Female subjects whose mothers were employed outside the home during the high school years (a) had a greater tendency to begin sexual relations before age 19, (b) expressed less concern regarding the risk of unintended pregnancy, and (c) scored lower on an objective test of their practical knowledge about contraception.Received Ph.D. in social psychology from the University of Washington.

While parents may not be recognized as disseminators of sexual information, positive and negative sexual messages are communicated by parents to their children, both verbally and nonverbally. The results of this study indicate that the impact of parental messages upon the sexuality of youth appears relatively straightforward for males, but quite complex for females. This article suggests educational approaches that can be used to recycle early parental sexual messages.This study was funded by the National Institute of Child Health and Human Development, #HD 10689-02. David J. Kallen, Department of Pediatrics/Human Development, College of Human Medicine, Michigan State University was the principal investigator.Received Ph.D. from Michigan State University. Current research interest is Human sexuality.Received Ph.D. from Pennsylvania State University. Current research interest is Relationships. 相似文献
