The Gang Resistance Education and Training (G.R.E.A.T.) program is a school-based gang prevention initiative developed in 1991 through the collaborative efforts of the Bureau of Alcohol, Tobacco, and Firearms, the Federal Law Enforcement Training Center, and the Phoenix Police Department. Uniformed law enforcement officers, certified as G.R.E.A.T. instructors, teach the 9-week curriculum to middle students. In 1994, the National Institute of Justice funded a national evaluation of the G.R.E.A.T. program. The process evaluation component of this larger study is reported. First, results of on-site observations of the G.R.E.A.T. Officer Training program, including an overview of the training activities, and the authors' assessment of the training process are reported. Second, observations of the implementation of the program by officers at six sites are reported. Of primary concern was whether the program delivered to students was similar to the program taught to the officers during the G.R.E.A.T. Officer Training. 相似文献

To date, most school-based research has used passive parental consent. However, the Family Privacy Protection Act of 1995 aims to change these requirements. The proposed legislation requires written parental consent if minors are to be asked "sensitive" questions as part of any program or activity funded in whole or in part by the federal government. This act is representative of a growing trend toward restricting research involving minors. Whether or not this act is passed by Congress, two lines of concern are highlighted by this legislation. The first deals with ethical issues surrounding consent procedures. For instance, are parental rights compromised when active consent is not mandated? A second line of inquiry pertains to the effect of active consent procedures on response rates and sample bias. In this article, the authors discuss ethical issues surrounding passive and active consent procedures and then report response rates from two projects in which active consent procedures were implemented. 相似文献

Jacob Taarup‐Esbensen 《Risk analysis》2019,39(4):749-760
This article describes how risk has been conceptualized in the business and organizational literature through four distinct transformations: from the techno‐scientific perspective to the cognitive, the social‐cultural, and, finally, to the constructionist perspective. Each domain conceptualizes risk in different ways, as organizations have found it difficult to understand and mitigate using the risk management tools available. Conceptualizing risk as sensemaking becomes relevant due to the complexity of information available to the risk manager, and, coupled with time constraints, this means that risk managers increasingly rely on making sense of possible threats rather than on the accuracy of the information received. This shift presents four contributions to the current literature. First, it suggests that the role of risk management is shifting from being technical in nature to being about risk sensemaking, where the manager engages with the social and physical environment with the aim of acquiring cues that could indicate how future events will unfold. Second, a sensemaking perspective implies a shift in the use of risk management systems from being “containers” of knowledge about past risk events to lending legitimacy to the plausibility of the success of future decisions. Third, the role of the risk manager in managing individual risks changes and becomes one of managing everything using the social networks and systems available as indicators of future risk events. Finally, the risk manager and the systems he or she relies upon are regarded as a source of risk in themselves as both act as gatekeepers for organizational risk decision making. 相似文献

The increased risk of violent victimization for adolescents relative to other age groups has recently become a major public health concern. The current study uses data from a multisite study of eighth grade youths attending public schools in 11 cities to determine the extent and nature of youth general and serious violent victimization among both sexes and five racial/ethnic groups in 11 diverse communities. This study explores differences in sex, race/ethnicity, and community independently and explores interactions between sex and community and race/ethnicity and community. Our findings suggest important differences in victimization prevalence and individual victimization rates by sex and community of residence. Racial differences were found to be closely tied to community. Policy implications resulting from our findings are discussed. 相似文献

Active parental consent in survey research poses ethical and practical concerns. One common argument against the requirement of active consent procedures is its effect on participation rates. There is additional concern that higher risk groups may be underrepresented in the final sample. Empirical support of differential attrition, however, is lacking. In the current multisite longitudinal study, passive consent procedures were approved for the collection of pretest data. For subsequent years of data collection, active parental consent procedures were required. In this article, we use the pretest data to examine demographic, attitudinal, and behavioral differences between those students for whom active consent was provided and those for whom active consent was either denied or for whom no response was received. The results indicate that active consent procedures produce deleterious effects on participation rates and lead to an underrepresentation of at-risk youth in the sample. 相似文献
