In this paper, we compare the results from a randomized clinical trial to the results from a regression discontinuity quasi-experiment when both designs are implemented in the same setting. We find that the results from the two approaches are effectively identical. We attribute the comparability in part to recent statistical developments that make the model required for the analysis of data from a regression discontinuity design easier to determine. These developments make an already strong quasi-experimental design even stronger.  相似文献

This article examines the impact of structural reforms and industrial relations changes on the employment security and decision behaviors of middle-level managers in the Australian Taxation Office (ATO). This article is based on an empirical study using focus group and survey data that investigated how structural change and public-sector reforms substantially altered the employment environment. This research reveals that the ATO environment can be characterized by low morale, risk aversion, fear, and distrust brought about, in part, by employment insecurity. Where middle managers perceived organizational threats to their employment security, they engaged in self-protective “survivor” behaviors even when no such threats to their employment security existed. The article concludes that a substantial number of middle-level managers, survivors of years of restructuring, downsizing, and organizational change, were unlikely to display high-quality decision-making behaviors.  相似文献

Though mentoring has emerged as a promising and low-cost intervention for at-risk youth in recent years, the scientific knowledge base on the topic remains under-developed. The current study augments the knowledge base on youth mentoring by analyzing programmatic elements of mentoring programs situated in or adjacent to the juvenile justice system that are predictive of participant success. Poisson regression was utilized to analyze data collected through a national mentoring community saturation survey. Findings indicated that mentoring programs that require more frequent interaction and sustain relationships for longer timeframes realize higher success rates. Similarly, the use of formal mentor training was also observed as indicative of the use of evidence based practices and higher success rates, though likely beyond the logistical and fiscal reach of some local mentoring initiatives. The implications for further research and the mentoring community are discussed.  相似文献

Purpose

The current study seeks to examine the relationship between low self-control and cigarette smoking, alcohol use, and marijuana use in adolescence and adulthood using behavioral genetic methodology.

Methods

Using a subsample of twin pairs from the National Longitudinal Study of Adolescent Health (Add Health), the current study estimates the genetic and environmental overlap between low self-control and substance use (or problems associated with substance use) across four waves of data collection.

Results

The overall pattern of results suggests that genetic factors explain a moderate proportion of the variance in low self-control and substance use in both adolescence and adulthood. Furthermore, bivariate genetic analyses reveal that the correlation between low self-control and substance use is due, for the most part, to common genetic and nonshared environmental factors.

Conclusions

The current study adds to a growing body of biosocial research on self-control and its relationship to criminal and analogous behaviors. The implications of our findings for the general theory of crime are discussed.  相似文献

Little is known about the transition to adulthood for adolescent females and young women who are impoverished and homeless. Co-occurrence of drug use and abuse, HIV risk, and victimization is notable among homeless women, highlighting the need for comprehensive interventions. Unfortunately, evidence-based prevention approaches addressing these inter-related problems among impoverished women transitioning into adulthood are lacking. To address this gap, we designed an innovative prevention program by utilizing open- and closed-ended interview data from impoverished women (n = 20), focus groups with community experts and providers (2 groups; n = 9), and a theoretical framework to direct the research. Information provided by our focus groups and interviews with women supported our theoretical framework and highlighted the importance of addressing normative information, providing skills training, and utilizing a non-confrontational approach when discussing these sensitive issues.  相似文献

In this paper we use evidence from the recent trajectories of mining industry associations in the Australian federation to argue for the significance of institutional explanations for the formation and maintenance of interest groups. We argue that the recent lack of consultation by the Commonwealth government with the Minerals Council of Australia over resources rent taxation proposals reflected a weakness that resulted from the shifting basis of associability stemming from institutional changes.  相似文献

Several years ago, a legislator spoke clearly of the wishful unawareness we often confront in public health. After a session of frank exchange in his committee about teen pregnancy in Arkansas, he said, "Dr. Elders, until you became the health department director, we didn't have this problem." The facts paint a startling scenario for such people. We have not provided an environment in which our children can flourish. Instead, we have allowed the number of children who are economically, educationally, and medically disadvantaged to grow. Called "at-risk," their existence is an affront to democratic ideals, especially the belief that all have an equal chance for prosperity. It is time for true reform, but before that can happen, we must face the state of our children's health. After this, we must set to work at effective strategies.  相似文献

The present analysis uses data from 1974 and 1981 U. S. cross sections, which incorporate a panel, to compare the standard NES measure of party identification (ID) with a measure of partisanship derived from a party closeness question widely employed in cross-national research. Important features of the two scales are examined by transforming the closeness measure into a scale of very close, fairly close, not very close, and no preference corresponding to the seven-point ID scale. The scales are highly correlated and are similar in their reliability. More than 75% of the independents in the ID scale choose a party in the closeness version, and over half of these select the fairly close category. Respondents do not volunteer that they are independents when that alternative is not stated in the question.  相似文献
