This study investigated relationships among factors hypothesized as related to job loss grief. A summary grief score correlated positively with time since job loss and number of dependents, and negatively with length of notice. Perceived reemployment prospects and income loss related positively to some grief index subscales, as did the condition of living on one's own. Job duration correlated negatively with some grief responses. Implications for counseling and avenues for future research are discussed.  相似文献

Timing of first fatherhood was examined in a sample of 206 at-risk, predominantly White men, followed prospectively for 17 years. An event history analysis was used to test a model wherein antisocial behavior, the contextual and familial factors that may contribute to the development of antisocial behavior, and common correlates of such behavior, including academic failure, substance use, and early initiation of sexual behaviors, lead both directly and indirectly to an early transition to fatherhood. Having a mother who was younger at first birth, low family SES, poor academic skills, failure to use condoms, and being in a cohabitating or marital relationship predicted entry into fatherhood. Implications of the findings for prevention of and intervention with early fathering are discussed.  相似文献

Data on cause of death are deficient for most developing countries. Nevertheless, it is important for policy makers to have access to such information to plan the use of resources and to evaluate health programs. In this study, deaths among women of reproductive age (15 to 49) in two areas in developing countries were located, and family members were interviewed. Local physicians reviewed the completed interviews and determined the cause of death.Complications of pregnancy and childbirth were the cause of 23% of the deaths in Menoufia, Egypt and Bali, Indonesia. In Egypt, the first cause of death was circulatory system disease (28%), followed by complications of pregnancy and childbirth (23%), and trauma (14%, primarily burns). In Indonesia, complications of pregnancy and childbirth was the first cause of death, followed by infectious disease (22%, primarily tuberculosis), and circulatory system disease (13%).Although the method of data collection was unorthodox, findings for Menoufia are comparable to data from other sources for the country as a whole. There are few data with which to compare our findings for Bali, but their similarity to the data from the Egyptian study lends credence to their quality.  相似文献

Gambling in young adolescents   总被引:1,自引:1,他引:0  
A questionnaire was used to investigate gambling in British adolescents. Responses from fifty 13- to 14-year-olds were analyzed. Gambling was found to be very pervasive (90% of subjects reported at least some gambling activity). Males gambled more than females, both in absolute terms and as a proportion of income. Income was found to have some influence on gambling behavior, but the effects of intelligence and social class were nonsignificant. Slot machines were the commonest form of gambling in both sexes.The willing cooperation of the teacher and students concerned is gratefully acknowledged. This paper is based on a report submitted by the first author in partial fulfillment of the requirements for the BSc degree at the University of Exeter. Some of the data were presented to the conference of the British Psychological Society Developmental Section, held in Exeter in September 1986, and to the colloquium of the International Association for Research in Economic Psychology, held at Aarhus, Denmark, in September 1987.  相似文献

A framework for analyzing the determinants of state labor relations policies is developed using the notion of tactics. Unions and management have various tactical options, at both the state and local levels, for influencing employment outcomes. The framework explicitly recognizes those options, and thus incorporates actions, such as bringing cases to courts, which have received little attention in previous research. Consideration of local-level tactics reveals additional factors that may influence interest group incentives to seek state-level policy changes. The author thanks Paul Jarley, John Delaney, Jim Bennett, and George Neumann for helpful comments on earlier drafts of this paper. This paper was partially supported by a University of Iowa Old Gold Summer Research Fellowship and a College of Business Administration Summer Research Grant.  相似文献
