The aim of this study was to investigate different trajectories of education, based on annual attendance in postcomprehensive and higher education between ages 15 and 42, and their correlates and antecedents. A special focus was on education that occurred after spending several years in the labor market (i.e., off-time education). Analyses were based on the Finnish Jyväskylä Longitudinal Study of Personality and Social Development in which the same participants have been followed from age 8 to 42. Four trajectories were obtained: no or early, off-time, on-time, and continuing education. Through adulthood, career stability, and occupational status were lower among off-time and no or early education participants than among the others. Women on the off-time education trajectory showed an increased level of optimism and achieved identity from age 27 to 42. Both off-time and no or early education participants came from a low socioeconomic (SES) family and had problems in their social behavior at age 8 and school adjustment at age 14. Different types of, and reasons for attending, adult education should be better understood, and adult education should be individually targeted .  相似文献

Although concerns have frequently been raised recently regarding the quality of life of intercollegiate athletes, information is seldom available on which college and university administrators can base policy decisions. Particularly lacking are studies that provide administrators with assessments of their own athletics programs relative to athletics programs at other institutions. We describe here a method we used in conducting a comparative evaluation of the status of student-athletes at a large public university, involving comparisons of student-athletes at this university to student-athletes at a subset of the institutions that participated in the 1987–88 National Study of Intercollegiate Athletes. By utilizing existing data sets to construct comparison samples, relative assessments of the status of student-athletes at a given institution can be performed without the excessive costs of gathering data on student-athletes at comparison institutions. Techniques employed in data collection and analysis are discussed as well as the format of the report in which the findings of the study were presented.  相似文献

Abstract

This paper discusses participatory research with young people who are leaving public care in Finland to begin independent lives. The aim of the research, organised by SOS Children's Villages International, was to bring about change in alternative care arrangements, particularly those involving young people's transition to independence. The project used a participatory research design based on employing care-leaving peers as co-researchers. This paper adheres to the methodological principles of empowerment in analysing the personal experiences of young people leaving alternative care with the goal of informing good practice. The findings suggest that the peer research method can be an effective means of empowering young people to develop research skills and to be involved in knowledge production, as well as serving as a means of promoting improved services for “care-leavers”, those young people who are leaving either foster care or institutional care. The participatory and peer research method challenges the traditional understandings of expertise and knowledge production. Although the hierarchy between adult researchers and young people as co-researchers is still evident, the method provides possibilities for better understanding the social- and health-service systems and their challenges and pitfalls from a user's perspective.  相似文献

Although attachment security has been associated with children's rule‐compatible conduct, the mechanism through which attachment influences early regard for rules is not well established. We hypothesized that effortful control would mediate the link between security and indicators of children's emerging regard for rules (discomfort following rule violations, internalization of parents’ and experimenter's rules, few externalizing behaviors). In a longitudinal study, the Attachment Q‐Set was completed by parents, effortful control was observed, and Regard for Rules was observed and rated by parents. The proposed model fit the data well: Children's security to mothers predicted their effortful control, which in turn had a direct link to a greater Regard for Rules. Children's security with fathers did not predict effortful control. The mother‐child relationship appears particularly important for positive developmental cascades of self‐regulation and socialization.  相似文献

The aim of this study is to analyze the effect of fiscal policy by race, disaggregating to consider Uruguayans with primarily European, African and indigenous ancestry. We perform an incidence analysis, an estimation of the effect of fiscal policy on the poverty exit rate and an assessment of the impact on the average ethno-racial gaps. The findings support the idea that fiscal policy reduces (but does not eliminate) ethnic gaps. This result is led by health care and educational transfers, and to a lesser degree by direct transfers. We do not consider quality issues with public services, which may affect the estimated narrowing of gaps. Finally, we find that Afro-descendants and indigenous individuals do not capture the full potential of education transfers because of their high drop-out rate.  相似文献

This article considers in-sample prediction and out-of-sample forecasting in regressions with many exogenous predictors. We consider four dimension-reduction devices: principal components, ridge, Landweber Fridman, and partial least squares. We derive rates of convergence for two representative models: an ill-posed model and an approximate factor model. The theory is developed for a large cross-section and a large time-series. As all these methods depend on a tuning parameter to be selected, we also propose data-driven selection methods based on cross-validation and establish their optimality. Monte Carlo simulations and an empirical application to forecasting inflation and output growth in the U.S. show that data-reduction methods outperform conventional methods in several relevant settings, and might effectively guard against instabilities in predictors’ forecasting ability.  相似文献

In recent years, the lesbian and gay “scene” of bars, nightclubs, and dance parties has been undergoing a structural decline in many Western cities. This article aimed to examine the relevance of the scene to same-sex attracted young adults amid these changes. An online survey was conducted with 572 same-sex attracted young women and men in Sydney. Only a minority of respondents participated in the scene at least weekly (16%), and the majority did not regard the scene as important to their leisure time (60%). However, respondents valued the scene as a space to connect with other same-sex attracted people and display same-sex affection without fear of hostility. Lesbian and gay identified respondents tended to be more socially engaged with the scene compared to other same-sex attracted respondents. The findings suggest that while the scene continues to be valued by many same-sex attracted young people, improved social attitudes have made participating in the scene less of an imperative.  相似文献

Despite more than thirty years of debate, disagreement persists among research ethicists about the most appropriate way to interpret the U.S. regulations on pediatric research, specifically the categories of “minimal risk” and a “minor increase over minimal risk.” Focusing primarily on the definition of “minimal risk,” we argue in this article that the continued debate about the pediatric risk categories is at least partly because their conceptual status is seldom considered directly. Once this is done, it becomes clear that the most popular strategy for interpreting “minimal risk”—defining it as a specific set of risks—is indefensible and, from a pragmatic perspective, unlikely to resolve disagreement. Primarily this is because judgments about minimal risk are both normative and heavily intuitive in nature and thus cannot easily be captured by reductions to a given set of risks. We suggest instead that a more defensible approach to evaluating risk should incorporate room for reflection and deliberation. This dispositional, deliberative framework can nonetheless accommodate a number of intellectual resources for reducing reliance on sheer intuition and improving the quality of risk evaluations.  相似文献
