The objectives of this research were to explore patterns of heterosexual activity in early adolescence and to examine the differential pathways to light and heavy heterosexuality. We utilized the National Longitudinal Survey of Canadian Children and Youth (NLSCY) in which heterosexual behaviors, as well as puberty, parenting processes, peer self‐concept, and problem behaviors were examined. The heterosexual activities of the majority of 12‐ and 13‐year‐old adolescents were largely confined to light activities of hugging, holding hands, and kissing. Heavy activities such as petting and sexual intercourse were reported less often. Using predictor variables from Cycle 1 of the NLSCY when participants were 10‐ and 11‐year‐olds, SEM analyses indicated that puberty and higher peer self‐concept shared significant direct pathways to both light and heavy heterosexuality. Heavy sexual activity, however, was uniquely associated with the risk factors of adolescent problem behaviors. Positive and hostile parenting styles were indirectly associated with light sexual activity through peer self‐concept. Positive and hostile parenting styles were also indirectly associated with heavy sexual activity through both peer‐oriented self‐concept and problem behaviors. Results support differential patterns and predictors of light and heavy sexuality in early adolescence. 相似文献

This study attempts to identify stimuli that produce changes in death penalty opinions and to determine whether public commitment to a death penalty opinion has an effect on that opinion. Consistent with previously reported findings, the results of this study suggest that public commitment has a substantial inhibitory effect on opinion change. Reasons for both changing and maintaining death penalty opinions are provided, and the implications of the research are discussed. 相似文献

Industrial/organizational researchers have reported that realistic job previews diminish prospective workers' expectations but promote the satisfaction and persistence of those who ultimately accept a job assignment. The authors applied this strategy to the context of school‐to‐college transition; 354 Italian high school students were provided with a 2‐hour lecture designed to simulate exposure to a college major of their choice. Students showed moderate pre‐post increases in subject matter knowledge but reported small decreases in interests and outcome expectations (but not self‐efficacy) related to the academic major to which they were exposed. 相似文献

Analysis reported here examined youth in residential group home placements in order to better understand how sexual behaviors,
drug use, and environmental experiences differ by race and gender subgroups. Data were collected from 336 youth aged 14–21
residing in one of 41 group homes in Maryland. Chi square and logistic regression analyses were done to determine differences
on study variables among the race-gender groupings. Results demonstrate not only significant health concerns overall but notable
differences were also found between race-gender subgroups. Findings suggest that found race-gender subgroup differences might
be informative for tailoring programming for youth of residential group home settings. 相似文献

This paper provides a review and synthesis of research literature on the effects of shift work on workers’ physical health,
mental health/well-being, and family life. The focus is on current knowledge, unanswered questions, and new directions for
future research. The selection of research literature is guided by a general conceptual framework that identifies predictor
variables, moderating variables, and outcome variables. The paper concludes with a discussion of the variables that should
be incorporated into an agenda for future research. 相似文献

This article employs two previously neglected indicators of racial prejudice from the British Social Attitudes surveys to examine the social distribution of prejudices against black and Asian Britons. Three hypotheses are proposed and tested: that racial prejudice is declining in Britain; that this decline is principally generational in nature; and that greater prejudice is shown towards more culturally distinct Asian minorities than black minorities. Strong evidence is found for the first two hypotheses, with evidence of an overall decline in prejudice and of a sharp decline in prejudices among generations who have grown up since mass black and Asian immigration began in the 1950s. Little evidence is found for the third hypothesis: British reactions towards black and Asian minorities are broadly similar suggesting racial differences may still be the main factor prompting white hostility to British minorities. 相似文献

This paper considers the difficulties associated with evaluating the expected value of additional information when the outcomes of various decision alternatives may be correlated. Such correlation is explained in terms of dependence of outcomes on common exogenous factors and it is argued that decisions regarding what, if any, additional information to collect should take such dependencies into account. A model-based ‘fixed-parameter’ approach to evaluating EVPI in such a context is developed and compared to the traditional ‘fixed-correlation’ approach. The results suggest that different assumptions about the issue of correlation can produce different, sometimes contradictory, conclusions about the expected value of additional information and bence, should be explicitly stated as part of any pre-posterior analysis. A hybrid model encompassing both approaches and rooted in the theory of psychology of inference is then proposed and illustrated. 相似文献

We describe the analysis of some matched-pair binary data arising from a study designed to investigate whether cellular-telephone use is associated with motor-vehicle collisions. Conditional and random effects approaches to the problem are derived and compared. Driving intermittency is a potential confounder whose effect is assessed by strategic choices of the control period and by application of the bootstrap. The marked discrepancy between the conditional and random approaches merits further study. 相似文献
