This paper reports on an exploratory study examining women's views about and experiences of retirement. It has long been recognized that women's careers often follow a different path than men's due to the differential impact of family and domestic responsibilities and their relative underrepresentation at higher levels of organizations. However, many studies of retirement have implicitly assumed a conventional male career as the norm, where retirement is seen as marking a neat ending to continuous employment. This paper aims to present a richer understanding of women's retirement, utilizing contextual national data and qualitative analysis. The paper begins with a brief summary of literature looking at women's career development. We then explore the concept of retirement and consider current literature with regard to women's retirement. Following a brief discussion of our research approach, we provide some national context using quantitative data. We then discuss the qualitative findings, examining the areas of continuity and change that women experienced in retirement and exploring the factors that they felt enabled and constrained them.  相似文献

This article examines the relationship between indigenous sovereignty and identification as instanced by the legal and political debates informing the Human Genome Diversity Project. The HGDP proposes to map the history of human origins and migrations by the identification and measurement of populations. I analyze the impact of the criticisms of this agenda and methodology by indigenous nations, organizations, and advocacy groups, focusing on the incommensurability of populations with indigenous identifications as peoples. My argument is that the work of identification is the mediation of the terms and conditions of indigenous sovereignty in the very real places where their intellectual property rights and the ethics of scientific research are negotiated.  相似文献

The main theme of this paper is improving project schedules by integrating the scheduling of project jobs and labour resources. An ILP model is presented of the integrated project operations and personnel scheduling problem with multiple labour categories. Traditionally, this problem is solved in two steps: first, operations are scheduled by solving the resource-constrained project scheduling problem; then, labour categories are scheduled by solving the personnel days-off scheduling problem. The proposed model combines the two stages into an integrated problem, which is solved in one step. Using 48 test problems, the two methods were compared in terms of total cost, labour cost and scheduling efficiency. The results clearly indicate that the integrated model outperforms the traditional two-step method.  相似文献

To determine whether eye contact elicits blushing due to anxiety, forehead blood flow was measured during a stressful quiz and self-disclosure. The investigator maintained eye contact with 19 participants whereas, in another 40 cases, the investigator and/or participant wore sunglasses or the investigator left the room (the control group). Anxiety, embarrassment, and forehead blood flow increased in both groups during the quiz, consistent with anxiety-evoked blushing. However, during self-disclosure, increases in forehead blood flow were greater in the eye contact than control group despite reductions in embarrassment and anxiety. These findings suggest that eye contact augments blushing over and above any influence of anxiety or general scrutiny during self-disclosure.  相似文献

In order to learn about the behaviours and health experiences of people who gamble on the Internet, we conducted an international online survey with respondents recruited via gambling and gambling-related websites. The mean (SD) age of the 4,125 respondents completing the survey was 35.5 (11.8) years, with 79.1% being male and 68.8% UK residents. Respondents provided demographic details and completed validated psychometric screening instruments for problem gambling, mood disturbances, as well as alcohol and substance misuse, and history of deliberate self harm. We applied latent class analysis to respondents’ patterns of regular online gambling activities, and identified subgroups of individuals who used the Internet to gamble in different ways (L 2 = 44.27, bootstrap P = 0.07). We termed the characteristic profiles as ‘non-to-minimal gamblers’; ‘sports bettors’; ‘casino & sports gamblers’; ‘lottery players’; and ‘multi-activity gamblers’. Furthermore, these subgroups of respondents differed on other demographic and psychological dimensions, with significant inter-cluster differences in proportion of individuals scoring above threshold for problem gambling, mood disorders and substance misuse, and history of deliberate self harm (all Χ 2s > 23.4, all P-values <0.001). The ‘casino & sports’ and ‘multi-activity-gamblers’ clusters had the highest prevalence of mental disorder. Internet gamblers appear to be heterogeneous but composed of several subgroups, differing markedly on both demographic and clinical characteristics.  相似文献

This study of a particular district of a Massachusetts town indicates how, over the space of some 70 years, patterns of work have changed dramatically. Making particular use of oral history methodology, the study identifies the changing significance of economic shifts over three generations and focuses on the ethnic composition of the workforce. It notes the differential experiences for the various groups and the processes whereby cultural values and family ties were gradually eroded as a more homogeneous ‘American’ economic and social pattern was imposed on the locality.  相似文献

Runaway and homeless youth are at high risk for substance abuse and unsafe sexual behavior. Our study describes the personal social networks of these youth and examines network characteristics associated with risky behaviors. In 1995 and 1996, we interviewed a purposive sample of youth aged 14 through 21 who were living in Washington, DC and were identified on the streets or through shelters or other service agencies (N = 327). Although we found that most youth reported current social relationships, a significant minority (26%) did not. Youth without a social network were significantly more likely to report current illicit drug use, multiple sex partners, and survival sex than youth with a network. For youth with a network, the networks were small, strong in affective and supportive qualities, comprised primarily of friends, typically included an alcohol or illicit drug user, and usually were not a source of pressure for risky behaviors. Our results indicate that networks had risk-enhancing and risk-decreasing properties in that network characteristics were associated in both positive and negative directions with risky behaviors.  相似文献
