Prior research found that lower sexual frequency and satisfaction were associated with higher rates of divorce, but little research had examined the role of sexual activity in the dissolution of cohabiting unions. We drew upon social exchange theory to hypothesize why sexual frequency is more important in cohabitation: (a) cohabitors' lower costs of finding sexual alternatives, (b) cohabitors' lower barriers to ending the relationship in the form of union‐specific economic and noneconomic capital, and (c) cohabitors' higher expectations for sexual activity. Using the National Survey of Families and Households (N = 5,902), we examined the relationship between sexual frequency and union dissolution. Results indicated that low sexual frequency was associated with significantly higher rates of union dissolution among cohabitors than married couples. 相似文献

This study uses a modified health belief model (HBM) within a socio-economic framework to evaluate the influence of awareness and knowledge on actions to reduce aflatoxin (AF) contamination in groundnuts (peanuts). Data were collected in 2002 through a self-administered questionnaire from a sample of 367 individuals. Socio-economic factors affecting perceptions, awareness, knowledge, and action were examined using structural equation modeling. The perceived benefits of good quality groundnuts and/or groundnut products were the most important determinants of awareness and knowledge of AF among agricultural and health professionals in Ghana. Awareness, in turn, had a significant causal effect on the professionals’ decisions to take actions to increase the level of awareness of AF in the society. Demographic factors, such as gender and level of education significantly influenced knowledge of AF and the perception of the benefits of good quality groundnut. Type of profession had a significant influence on awareness and perceived seriousness of the AF problem. Education was a significant determinant of awareness of AF in groundnuts. The study generates important information for policy decision making when considering resource allocation to reduce food contamination in developing economies. 相似文献

A multilevel model is offered proposing that organizational learning is an interdependent system where effective leaders enact intervention strategies at the individual (micro), network (meso), and systems (macro) levels. We suggest that leaders approach organizational learning by setting the conditions and structure for learning to occur, while limiting direct interference in the actual creative processes. First, leaders may increase the level of developmental readiness of individual followers, thereby increasing their motivation and ability to approach learning experiences and adapt their mental models. These individuals then serve as catalysts of learning within and between social networks. Second, leaders may promote the diffusion of knowledge between these knowledge catalysts within and across social networks through influencing both the structure and functioning of knowledge networks. Finally, leaders may target actions at the systems level to improve the diffusion to, and institutionalization of, knowledge to the larger organization. 相似文献

This article discusses a longitudinal study of firms selected for their expertise in environmental analysis. It is primarily designed to test two general propositions. The first, that environmental analysis is increasing in importance over time— both within and between firms; and the second, that environmental analysis is most viable as a separate, freestanding function within the organization. 相似文献

The authors of this article describe a study of European companies the aim of which was to review the extent of multiple scenario analysis in company planning. They describe the differences in planning between users and non-users of the system, and analyse the benefits and drawbacks of using the system. 相似文献

Laura Bragg, a member of the first graduating class at Simmons College, journeyed to Charleston as a New Woman in 1909. As the first woman director of a major scientific museum in the United States, Bragg transformed the Charleston Museum into a public education institution and became an innovative leader in museum education. This article documents Bragg's contributions within the context of antebellum culture where the Southern Belle was placed on a Victorian pedestal and Boston marriages were an unknown phenomenon. Using extensive and hitherto unpublished correspondence, the authors detail Bragg's lesbian relationships and describe her network within the homosexual male community during the era of the Charleston Renaissance. 相似文献

Stalking has been relatively understudied compared to other dimensions of intimate partner violence. The purpose of this article was to examine concurrent and subsequent intimate partner abuse, strategic responses and symptomatic consequences of severe stalking experienced by battered women. Thirty-five battered women classified as "relentlessly stalked" and 31 infrequently stalked battered women were compared. Compared to infrequently stalked battered women, relentlessly stalked battered women reported: (a) more severe concurrent physical violence, sexual assault and emotional abuse: (b) increased post-separation assault and stalking; (c) increased rates of depression and PTSD; and (d) more extensive use of strategic responses to abuse. Results underscore the scope and magnitude of stalking faced by battered women and have implications for assessment and intervention strategies. 相似文献

Younger women, relative to older women, incur elevated risk of uxoricide-being murdered by their husbands. Some evolutionary theorists attribute this pattern to men's evolved sexual proprietariness, which inclines them to use violence to control women, especially those high in reproductive value. Other evolutionary theorists propose an evolved homicide module for wife killing. An alternative to both explanations is that young women experience elevated uxoricide risk as an incidental byproduct of marriage to younger men who commit the majority of acts of violence. We used a sample of 13,670 uxoricides to test these alternative explanations. Findings show that (a) reproductive-age women incur an elevated risk of uxoricide relative to older women; (b) younger men are overrepresented among uxoricide perpetrators; and (c) younger women, even when married to older men, still incur excess risk of uxoricide. Discussion examines competing explanations for uxoricide in light of these findings. 相似文献
