Objective. Taking an institutional approach to the determinants of outcomes for women in science and engineering, we examine the effects on women's percentages among undergraduate majors and among degree recipients of four basic factors: (1) the percentage of faculty who are women in the students' major science/engineering area; (2) the students' disciplines (biology, physical sciences, and engineering); (3) the type of institution in which students are enrolled (“Research I” vs. others); and (4) a time trend (1984–2000). Method. We use longitudinal, multivariate, and multi‐institutional data from the Integrated Postsecondary Data System (IPEDS) and from a mail survey of registrars. Results. Over the observation period, the women's percentages have risen steadily. The effects of disciplines and departments are stronger than those of institutions. Especially notable is that the percentages of women among undergraduate science/engineering majors and degree recipients are associated with the percentages of women among the faculty in these fields. Conclusion. The findings contribute empirically to the discussion about the effects of “role models” for the participation and performance of women in science and engineering—and point to the strong effects of departments, compared to institutions, in accounting for degrees awarded to undergraduate women. 相似文献

Fledgling therapists who graduate from family therapy traning programs will have to navigate the world of managed care. In this article, faculty of University of San Diego share changes in its accredited training program that prepare students for practice in an increasingly multidisciplinary world where health maintenence organizations and other versions of managed care predominate. The paper touches on contextual issues, provides a detailed outline of coursework presenting basic knowledge and skills involved in clinical pracice in a managed care environment, and comments on clinical placements and the challenge of helping the next generation of clinicans "fit" into the future of health care delivery while maintaining their unique identity as family therapists. 相似文献

In the literature on M&A and social justice, equality is regarded as an important principle to facilitate social integration. This article debates what happens when the equality principle is operationalized; from intentions in the pre‐merger process to the distribution of resources and decision‐making rules in the post‐merger process. In a merger between two state‐owned telecoms corporations in the Scandinavian countries, we found that the principle of equality had the reverse effects on social integration to that predicted in the literature. Instead of facilitating the social integration process, the equality principle led to perceptual and structural fallacies negatively influencing social integration. We suggest that these disintegrating effects were particularly strong because this was an international merger between two state‐owned firms of unequal size. 相似文献

We argue that regional comparison of East Asian and European ethnic return migration policy offers important new perspectives on nationhood, nondiscrimination norms, and trans‐nationality. We find that despite international nondiscrimination norms, preferential ethnic return policy is common in both regions. These policies at least implicitly define the nation as existing across borders. However, there are significant regional differences. East Asian states use co‐ethnic preferences instrumentally for economic goals and also offer preferential treatment of co‐ethnic foreign investors. European states offer preferences to coethnics to protect these populations or express symbolic ties, sometimes at great expense. Thus, in Europe the state has an obligation to assist coethnics abroad, but in Asia, foreign coethnics assist the state. 相似文献

Diesel Engine Exhaust and Lung Cancer Mortality: Time‐Related Factors in Exposure and Risk 下载免费PDF全文
Suresh H. Moolgavkar Ellen T. Chang Georg Luebeck Edmund C. Lau Heather N. Watson Kenny S. Crump Paolo Boffetta Roger McClellan 《Risk analysis》2015,35(4):663-675
To develop a quantitative exposure‐response relationship between concentrations and durations of inhaled diesel engine exhaust (DEE) and increases in lung cancer risks, we examined the role of temporal factors in modifying the estimated effects of exposure to DEE on lung cancer mortality and characterized risk by mine type in the Diesel Exhaust in Miners Study (DEMS) cohort, which followed 12,315 workers through December 1997. We analyzed the data using parametric functions based on concepts of multistage carcinogenesis to directly estimate the hazard functions associated with estimated exposure to a surrogate marker of DEE, respirable elemental carbon (REC). The REC‐associated risk of lung cancer mortality in DEMS is driven by increased risk in only one of four mine types (limestone), with statistically significant heterogeneity by mine type and no significant exposure‐response relationship after removal of the limestone mine workers. Temporal factors, such as duration of exposure, play an important role in determining the risk of lung cancer mortality following exposure to REC, and the relative risk declines after exposure to REC stops. There is evidence of effect modification of risk by attained age. The modifying impact of temporal factors and effect modification by age should be addressed in any quantitative risk assessment (QRA) of DEE. Until there is a better understanding of why the risk appears to be confined to a single mine type, data from DEMS cannot reliably be used for QRA. 相似文献

Manager Characteristics and Employee Job Insecurity around a Merger Announcement: The Role of Status and Crossover 下载免费PDF全文
Jack Lam Kimberly Fox Wen Fan Phyllis Moen Erin Kelly Leslie Hammer Ellen Ernst Kossek 《The Sociological quarterly》2015,56(3):558-580
Most existing research theorizes individual factors as predictors of perceived job insecurity. Incorporating contextual and organizational factors at an information technology organization where a merger was announced during data collection, we draw on status expectations and crossover theories to investigate whether managers' characteristics and insecurity shape their employees' job insecurity. We find having an Asian as opposed to a White manager is associated with lower job insecurity, whereas managers' own insecurity positively predicts employees' insecurity. Also contingent on the organizational climate, managers' own tenure buffers, and managers' perceived job insecurity magnifies insecurity of employees interviewed after a merger announcement, further specifying status expectations theory by considering context. 相似文献

This article outlines briefly the development of matrimonial property law from earliest times to the present day. The issue of central concern throughout is the changing status of women and the bearing that this has had on development of the law. A historical, social and economic perspective is adopted in an effort to explain why particular developments occurred when they did. Finally, attention is drawn to the inadequacies of legal solutions to what is perceived as basically an economic issue. 相似文献
