A meta-analysis of the California school-based risk reduction program   总被引:4,自引:0,他引:4  
Prominent nonquantitative reviews of research evaluating school-based interventions designed to deter adolescents from the use of tobacco, alcohol and other drugs found the methodology to be flawed and thus little evidence existed that the interventions had the desired impact. Recent meta-analytic reviews indicate that information-focused interventions have more impact upon knowledge but less upon attitudes and behavior whereas alternative interventions have less impact upon knowledge but more upon attitudes and behavior. This result is replicated by the current meta-analysis performed upon eight risk-reduction programs meeting six standard methodological requirements for evaluation research.  相似文献

Using the concepts of ‘social capital deficit’ and ‘return deficit’, this study considers the social network aspects of social disadvantage among Malays in Singapore, as compared to Singaporean Chinese. Analysing a 2005 representative survey, we find Malays have less social capital than Chinese, a social capital deficit partly explained by their lower educational attainment. We find no return deficit in earnings: that is, every additional unit of social capital increases earnings equally for Chinese and Malays. However, we find return deficits in education: every additional unit of social capital (e.g. ties to educated parents) increases educational attainment more for Chinese than Malays. In all, this study offers a social capital explanation for Malay ‘plight’, complementing the more conventional explanations of human and economic capital.  相似文献

Social mobility is now a matter of greater political concern in Britain than at any time previously. However, the data available for the determination of mobility trends are less adequate today than two or three decades ago. It is widely believed in political and in media circles that social mobility is in decline. But the evidence so far available from sociological research, focused on intergenerational class mobility, is not supportive of this view. We present results based on a newly‐constructed dataset covering four birth cohorts that provides improved data for the study of trends in class mobility and that also allows analyses to move from the twentieth into the twenty‐first century. These results confirm that there has been no decline in mobility, whether considered in absolute or relative terms. In the case of women, there is in fact evidence of mobility increasing. However, the better quality and extended range of our data enable us to identify other ‘mobility problems’ than the supposed decline. Among the members of successive cohorts, the experience of absolute upward mobility is becoming less common and that of absolute downward mobility more common; and class‐linked inequalities in relative chances of mobility and immobility appear wider than previously thought.  相似文献

Although field experiments have documented the contemporary relevance of discrimination in employment, theories developed to explain the dynamics of differential treatment cannot account for differences across organizational and institutional contexts. In this article, I address this shortcoming by presenting the main empirical findings from a multi‐method research project, in which a field experiment of ethnic discrimination in the Norwegian labour market was complemented with forty‐two in‐depth interviews with employers who were observed in the first stage of the study. While the experimental data support earlier findings in documenting that ethnic discrimination indeed takes place, the qualitative material suggests that theorizing in the field experiment literature have been too concerned with individual and intra‐psychic explanations. Discriminatory outcomes in employment processes seems to be more dependent on contextual factors such as the number of applications received, whether requirements are specified, and the degree to which recruitment procedures are formalized. I argue that different contexts of employment provide different opportunity structures for discrimination, a finding with important theoretical and methodological implications.  相似文献

Prior to 2007, two systems of bus driver compensation coexisted in Santiago, Chile: one paid drivers per passenger transported, while the other paid a fixed wage. Per‐passenger drivers engaged in “The War for the Fare,” altering their driving patterns to compete for passengers. Examining these systems on similar routes in Santiago, we observed two key findings. Compared with the fixed‐wage system, the per‐passenger system leads to (1) 13% shorter passenger wait times, via reduced bunching of buses and (2) 67% more accidents per kilometer driven, via more aggressive driving. We discuss implications for the design of incentives in public transit. (JEL L92, M52, R41)  相似文献

Preferential trade agreements (PTAs) have proliferated over the past 60 years. While a small number of recent studies have examined empirically the economic determinants of the likelihood of a pair of countries having a PTA, this study explains empirically the timing of all PTA formations and enlargements from 1950 through 2006 using duration analysis. Our main and novel goal is to predict (in‐ and out‐of‐sample) a substantive share of these 1,560 PTA events using a parsimonious model with mainly economic variables, taking selection dynamics into account. Our analysis reveals that we can predict correctly in‐sample the actual year of entry into force for 26% of the 1,560 bilateral PTA formations/enlargements in the period 1950–2006 among 10,518 pairings of 146 countries using only a few economic and political variables. Moreover, we can predict correctly in‐sample 57% of these PTA events within a 10‐year window leading up to the event using this model. The model also performs well out‐of‐sample for the near term (82%), but not if the out‐of‐sample period is very long. We conclude with an evaluation of the model's ability to predict the timing of the North American Free Trade Agreement, the European Union's formation and enlargements, and the model's ten most likely post‐2006 PTA events.

For over 20 years, family therapist Karl Tomm has been engaging families and couples with a therapeutic intervention he calls Internalized Other Interviewing (IOI). The IOI (cf. Emmerson‐Whyte, 2010; Hurley, 2006) entails interviewing clients, from the personal experiences of partners and family members as an internalized other. The IOI is based on the idea that through dialogues over time, one can internalize a sense of one's conversational partner responsiveness in reliably anticipated ways. Anyone who has thought in a conversation with a family member or partner, “Oh there s/he goes again,” or anticipates next words before they leave the other's mouth, has a sense of what we are calling an internalized other. For Tomm, the internalized anticipations partners and family members may have offers entry points into new dialogues with therapeutic potential—particularly, when their actual dialogues get stuck in dispreferred patterns.  相似文献

Rural custodial grandparents have been understudied. As the grandparent caregiving population increases, more attention is needed to understand custodial grandparents in rural settings. This article explores the state of knowledge of the experiences of rural grandparents. A systematic review of the caregiving literature is conducted to understand the issues affecting this caregiving population. The results suggest that rural grandparents often are minority grandmothers with limited resources who provide care to older grandchildren in isolated environments. Attention is given to the social ecological framework as one model that can help to inform how social workers intervene with this population. Recommendations are offered for social work research, practice, and policy.  相似文献

Over half of the people who become disabled whilst employed are thought to be pressured into leaving their job. This study investigates the experience of involuntary retirement/redundancy due to disability. Three researchers who had all experienced such involuntary job loss were trained to conduct the research. Semi-structured interviews were designed and conducted by disabled researchers. The training of the researchers enabled them to successfully conduct a research project. The results of the project show the impact of involuntary job loss due to disability to be considerable. This study would suggest that government reforms to create new opportunities for disabled people of a working age are well overdue. Although there were some problems experienced with the amount of training required and the lack of objectivity, training disabled researchers to conduct research proved to be a valuable experience for both the researchers and the facilitators.  相似文献
