Abstract Lester and Perez1 have suggested that student behavior can be usefully construed in terms of a traditional-hedonic, implicit value system. They demonstrated that drug use and sexual activity provide simple behavioral anchors for this dimension, and observed an increasingly hedonic orientation among students. Ten years after their initial study, the student population at the same institution was again sampled using an anonymous questionnaire. The 1980 sample included 208 subjects, and these were compared with 688 subjects who responded to the 1970 survey. This comparison was supplemented by an intensive week-long study of 53 students within one campus living unit. Significant increases in pre-college sexual activity were noted for both men and women. Marijuana use in high school also increased for both men and women during this period, while alcohol use increased only among women. Previously observed differences between male and female pre-college sexual activity and marijuana use had largely disappeared by 1980. Significant increases in sexual activity while in college were found for women but not for men. For men, overall marijuana and alcohol use in college did not change during the study period, but there was an increase in the frequent use of these drugs. Increases in all categories of marijuana use were noted among women, along with overall increases in their alcohol use. The significant differences between male and female marijuana use noted in the 1970 study were absent in 1980. The intensive week-long study revealed that alcohol use was part of the daily lives of one-third to two-thirds of the students sampled, although they reported interpersonal conflicts, absences from class, accidents, and injuries among the consequences of their drinking. A significant inverse relationship between sleep and alcohol use was observed among women, but not among men. These data suggest that student behavior has become increasingly hedonic during the past ten years, with women in particular closing the gap which previously differentiated their behavior from that of their male peers. Institutions of higher learning must take these changes into account in the planning of academic programs, residential life, and health services. 相似文献

The study describes an evaluation of a 48‐week physical activity and nutritional education programme for overweight/obese school‐age children using quantitative and qualitative methods. The majority of participants were obese or severely obese when enrolled, and while some improvements in body mass index, self‐esteem and engagement in a range of physical activities were noted, difficulties in evaluating a complex community‐based intervention were highlighted. Children, parents and health professionals described a range of benefits from attending the programme but more intensive services are likely to be needed for the most seriously obese children and for those families resisting intervention. 相似文献

David Lewis 《Voluntas: International Journal of Voluntary and Nonprofit Organizations》2014,25(5):1132-1150
Since third sector research emerged as a full-fledged interdisciplinary academic field during the late 1980s, a separation has usually been maintained—in common with many other social science disciplines—between communities of researchers who are primarily concerned with the study of the third sector in rich Western countries and those who work on the third sector in the so-called developing world. Whilst internationally focused researchers tend to use the language of ‘non-governmental organizations’, those in domestic settings usually prefer the terms ‘non-profit organization’ or ‘voluntary organization’, even though both subsectors share common principles and are equally internally diverse in terms of organisations and activities. Whilst there has long been common-sense logic to distinguishing between wealthier and poorer regions of the world based on differences in the scale of human need, the ‘developed’ versus ‘developing’ category can also be criticised as being rather simplistic and unhelpfully ideological. As the categories of ‘developing’ and ‘developed’ countries become less clear-cut, and global interconnectedness between third sectors and their ideas grows, this paper argues that we need to reconsider the value of maintaining these parallel worlds of research, and instead develop a more unified approach. 相似文献

Gail Lewis 《Cultural Studies》2013,27(6):866-886
This article engages a discussion of Raymond Williams claim that culture is ordinary to explore some of the ways in which racializing culture is embedded in everyday interactions and processes of identification that found subjectivity. It argues that there is a pressing need for social policy analysts to come to grips with the mechanisms through which ‘culture’ comes to be racialized and an object/subject of governance and suggests that current, high-profile articulations of the ‘problems’ of multiculturalism, profoundly hinder such a development. 相似文献

In robust parameter design, variance effects and mean effects in a factorial experiment are modelled simultaneously. If variance effects are present in a model, correlations are induced among the naive estimators of the mean effects. A simple normal quantile plot of the mean effects may be misleading because the mean effects are no longer iid under the null hypothesis that they are zero. Adjusted quantiles are computed for the case when one variance effect is significant and examples of 8-run and 16-run fractional factorial designs are examined in detail. We find that the usual normal quantiles are similar to adjusted quantiles for all but the largest and smallest ordered effects for which they are conservative. Graphically, the qualitative difference between the two sets of quantiles is negligible (even in the presence of large variance effects) and we conclude that normal probability plots are robust in the presence of variance effects. 相似文献

This study examined whether variation on the cultural constructs of individualism–collectivism in a sample of predominantly majority culture (i.e., Anglo American) college students accounts for significant amounts of variance in their occupational choices, career plans, and work values. Participants (135 women, 55 men) responded to the “I am” sentence completion method (Kuhn & McPartland, 1954), the Occupational Plans Questionnaire (Hershenson, 1967), and the Work Values Inventory (Super, 1970). Overall, results indicated no significant relationships between level of collectivism and the career-related variables. 相似文献

Nearly ten years have passed since the publication in August 1974 of the draft Reactor Safety Study (WASH 1400), the first detailed attempt to apply probabilistic risk assessment (PRA) techniques to estimate the public risks posed by commercial nuclear power plants. Now is an opportune time to look back and see how PRA has fared over these ten years. We will not attempt to pass judgement on how the Reactor Safety Study report itself has withstood the test of time, as that task is best left to others less directly involved in preparing the report. Instead, we will examine advances in the understanding, acceptance, and utilization of PRA techniques, as well as technical advances in PRA methods. Some of the significant insights gained from PRAs will be discussed. Finally, some observations on the future of PRA will be offered. 相似文献
