The study examined differences in job search intensity, attitudes toward unemployment, and related responses among four age groups of jobless women in Israel, all of whom were married: Post-adolescence (up to age 21); young adulthood (age 22–35), mid-life (age 36–49); and late adulthood (50–62). The findings revealed differences in job search intensity for the four age groups. The youngest group spent more time seeking employment per week than did the other groups. At the same time, women in the late adulthood group were least likely to reject job offers owing to financial considerations, whereas those in the young adult and mid-life groups tended to reject job offers either due to conflict with family obligations or to work conditions. Moreover, the older respondents reported a sharper decline in health following unemployment than did their younger counterparts. In the same vein, members of the late adulthood group reported less financial strain as a result of unemployment than did the rest of the groups.  相似文献

This article is concerned with men and women's experience of elite positions and with the extent to which such positions are seen as places for women, so as to provide an insight into their commitment to continuing in them. Senior management in universities are elite positions in terms of income; those who occupy them are relatively powerful internally, although relatively powerless in relation to the state and the market. Drawing on a purposive study of those at the top three levels (i.e. presidential, vice-presidential, and dean) in public universities, it finds little difference between men and women's perceptions of the advantages/disadvantages of these positions. However, in a context where roughly four-fifths of those in university senior management are men [O'Connor, P. 2014. Management and Gender in Higher Education. Manchester: Manchester University Press.], at the level of organisational narratives and at the interactional level, gender differences persist. These differences are reflected in variation in commitment to continuing in senior management positions.  相似文献

Although gender gaps have been a major concern in male-dominated science, technology, engineering, and mathematics disciplines such as physics and engineering, the numerical dominance of female students in biology has supported the assumption that gender disparities do not exist at the undergraduate level in life sciences. Using data from 23 large introductory biology classes for majors, we examine two measures of gender disparity in biology: academic achievement and participation in whole-class discussions. We found that females consistently underperform on exams compared with males with similar overall college grade point averages. In addition, although females on average represent 60% of the students in these courses, their voices make up less than 40% of those heard responding to instructor-posed questions to the class, one of the most common ways of engaging students in large lectures. Based on these data, we propose that, despite numerical dominance of females, gender disparities remain an issue in introductory biology classrooms. For student retention and achievement in biology to be truly merit based, we need to develop strategies to equalize the opportunities for students of different genders to practice the skills they need to excel.  相似文献

In this paper, using the energy concept, the control of traffic flow by traffic lights on an over-saturated single intersection is addressed. By regarding the flow entry of vehicles as the energy stored in the system, we show that the dissipative system theory can be applied. As a result, a state feedback control law is found in terms of the solution of an associated dissipation equation that renders the system non-accumulative, i.e., to get out of the over-saturation situation. The results of the simulations indicate that our control strategy guarantees a high degree of control benefit.  相似文献
