The problem of adolescent substance use has been examined extensively. Beyond simple prevalence estimates, however, little research has been conducted on substance use in the school context. The present investigation was an in‐depth study of students' attitudes and behaviors regarding alcohol and marijuana use during the school day. Based on a representative sample of 1123 high school students, this study assessed the frequency of alcohol and marijuana use at school among demographic subgroups, the accessibility of drugs in school, and students' perceived consequences of being caught using drugs in school. The results showed that male and Hispanic students had higher levels of drug use at school than female and white students, respectively; that school drug use increased with age, and that alcohol and marijuana were easily obtained and used on school grounds. A large percentage of students were not aware of the specific actions taken in their schools to punish drug use. The need for additional research on school‐related drug use is emphasized. 相似文献

Today, many countries spend a great deal of money and effort on programs for expert-guided parenting support to be carried out in face-to-face groups. One goal of such support is to target, help, and educate “risky” groups of parents, such as young parents. It is striking, however, that young parents have a conspicuously low degree of participation in this type of parenting support. Drawing on the assumption that many young parents go online to seek, give, and receive peer parenting support, this paper presents a case study of activities within three Facebook groups. Using a combination of social network analysis, online ethnography, and interviews, we analyze how social network relationships and discussions differ depending on whether the analyzed Facebook group in question is administrated by professionals or peers, what the role of professional experts is, and how young parents might use social media to take control of their own support needs. Our results indicate that some of the affordances provided by Facebook might contribute to a challenging of the roles of “skilled” professionals versus “risky” young parents. 相似文献

This paper presents the results of a survey on the use of computer-based models in the broad areas of planning and strategy formulation in UK companies. This survey updates and complements other recent surveys, which exclusively considered the use of corporate models, and shows a continued increase in the numbers of these models in use. In particular, models in the following broad categories were examined: forecasting, marketing, personnel, production and models of ‘one-off’ situations, as well as corporate and financial models. For such models the paper includes details of: frequencies of occurrence and relationship to company size; professional roles of the model-builders and users respectively; frequencies of use. In these and more subjective ways, the survey attempts to assess the place and value of computers in planning. 相似文献

There are marked differentials in mortality risks across regions in Finland. No exhaustive explanation to this variation has been provided, however. The aim of this paper is to analyse how geographic ancestry, as proxied by persons’ birth region and population group, interrelates with cause-specific mortality risks. Focusing on people aged between their mid-thirties and late-forties, we use longitudinal population register data that offer opportunities to account for variables that represent both persons’ social background and their own social status at young adult age. Results of Cox proportional hazard models say that these variables have substantial effects on mortality of different causes, but only a marginal impact on the variation in death rates by birth region and population group. The geographic mortality pattern is found to be specifically prominent for causes of death that are fairly unrelated to persons’ lifestyles. Our findings suggest that genetic predisposal as expressed in terms of geographic ancestry might play a relevant role in understanding mortality variation within the population of Finland. 相似文献

We construct demographic models of retirement and death in office of U.S. Supreme Court justices, a group that has gained demographic notice, evaded demographic analysis, and is said to diverge from expected retirement patterns. Models build on prior multistate labor force status studies, and data permit an unusually clear distinction between voluntary and “induced” retirement. Using data on every justice from 1789 through 2006, with robust, cluster-corrected, discrete-time, censored, event-history methods, we (1) estimate retirement effects of pension eligibility, age, health, and tenure on the timing of justices’ retirements and deaths in office, (2) resolve decades of debate over the politicized departure hypothesis that justices tend to alter the timing of their retirements for the political benefit or detriment of the incumbent president, (3) reconsider the nature of rationality in retirement decisions, and (4) consider the relevance of organizational conditions as well as personal circumstances to retirement decisions. Methodological issues are addressed. 相似文献

This paper assesses the contribution of South African nongovernmental organizations (NGOs) to the process of democratic consolidation. By drawing on a 1998 survey conducted among 270 NGOs, on several expert interviews, and on an analysis of the structures and programmes of the umbrella body of South African NGOs (Sangoco), the author presents a multi-faceted picture of the activities of the South African NGO sector. The focus is on the NGOs' role as (1) schools of democracy, (2) in bridging societal cleavages, and (3) in providing channels of interest representation for the most marginalized sections of the population. The paper concludes that the contribution of South African NGOs to the process of democratic consolidation is significant, but highly dependent on an enabling external environment. 相似文献
