Abstract Despite the fact that women engineering students perform as well as their male classmates during college, women engineers report lower salaries and supervisory responsibility levels after about five years in the labour force. Several hypotheses concerning the reasons for the differences in career advancement of men and women engineers were investigated in a national survey of engineers in the United States. The gender differences in career advancement could not be explained by differences in education level or in self-perceptions of ability. The fact that women were more likely to have taken a career break than were men did decrease their salaries and supervisory levels. However, gender differences were still apparent even when this factor was controlled. The careers of both men and women were affected by conflicts arising from the multiple roles of worker, spouse, and parent, but many women engineers avoided such conflicts by remaining single and childless. These results challenge several popular explanations for the differential advancement of men and women, but the actual causes remain unknown. 相似文献

This article, based on documents from a Kyiv archive, explores the preconditions of famine in Ukraine through the 3rd All-Ukrainian Party Conference of July 1932, convened to discuss the grain crisis in the republic. It discusses recent historiography on the subject and the findings of Ukrainian historians. It argues that the causes of the famine may need to be broadened and that the argument that the famine should be regarded as genocide based on ethnic cleansing of Ukrainians is too narrow. Other factors that need to be considered are ignorance of local conditions, based in part on administrative restructuring during the time of the grain procurements campaign, lack of farming experience on the part of plenipotentiaries sent to the villages, overuse and misuse of land, a dramatic drop in livestock prior to 1932–1933 linked to collectivization, and above all the incompetence of Soviet party and government leaders at all levels. 相似文献

AbstractObjective: This study was conducted to determine the impact of dietary acculturation on the health status of newly arrived international students at Virginia Tech in Fall 2010. Participants: Thirty-five international students, 18–36 years of age, completed the study. Methods: Data were collected at 3 different time periods (V1, V2, and V3) approximately 6 weeks apart. A food frequency– and dietary pattern–related questionnaire was administered and numerically coded responses were analyzed. Twenty-four-hour dietary recall data were also collected at V1, V2, and V3. Body weight, fasting blood glucose level, and blood pressure of study participants were also determined at each time period. Results: Total sample population (TSP) had a significant increase in mean weight of 2.79 lb from visit 1 (V1) to visit 3 (V3) (p = .0082). Ten participants gained an average of 9.0 lb (participants who gained weight; n = 10). There was also an increase in the frequency of consumption of high-calorie American food items from V1 to V3. However, there were no significant changes in mean systolic blood pressure and mean fasting blood glucose was significantly lower at V3 than at V1. Conclusions: There was a gradual shift in the dietary patterns of international students towards the American diet. Dietary acculturation led to weight gain among some of the students, which may potentially have a negative impact on their health status if continued for longer time periods. 相似文献

I review the recent literature on the determinants and effects of right-to-work (RTW) laws. The focus is primarily on the
econometric studies published since the early 1980s. Five major areas of impact are assessed: unionization, free riding, union
organizing activities and successes in NLRB elections, wage structure, and state industrial development. While individual
findings are quite sensitive to model specification, the accumulated evidence indicates that RTW laws have at least a significant
short-run impact on all of these areas except perhaps wages. 相似文献

Based on research showing that alcohol expectancy and gender both play a role in sexual perceptions, we factorially crossed the apparent drinking status of yoked pairs consisting of a participant and a target person (a confederate posing as co‐participant). Alcohol expectancy interacted with gender in complex ways to influence sexual perceptions. We also found behavioral effects: men showed more erotic material to both male and female targets than women did. Men perceived the target as more sexually aroused by erotic material than women did. Men also showed more erotic material to drinking targets than to non‐drinking targets. Sexual perceptions and erotica‐showing behavior were correlated significantly and positively. We discuss these findings in terms of implications for postdrinking heterosexual encounters. 相似文献

In an effort to clarify alternative approaches to organizational analysis, this paper is concerned to stimulate the debate on how an inquiry into organizational phenomena, in general, and organizational learning, in particular, can be accomplished. Encouraging attention to different aspects of various paradigmatic approaches, the paper focuses on critical theory, postmodernism and social constructionism and how these paradigms have contributed and can contribute to the research in the subject domain of organizational learning. To this end, a paradigmatic review of the literature on organizational learning is offered in this paper. Organizational learning, as the study of learning processes of, and within, organizations, has attracted significant attention in academe since the early 1980s. There is a plethora of studies on organizational learning, which offer rich material for a paradigmatic review. This study highlights the need for further development of the field from alternative paradigmatic perspectives, with a view to generating more insights into the multifaceted, complex and changing nature of learning in contemporary organizations. 相似文献
