This study examines the features of effective school-based prevention of crime, substance use, dropout/nonattendance, and other conduct problems. It summarizes, using meta-analytic techniques, results from 165 studies of school-based prevention activities that ranged from individual counseling or behavior modification programs through efforts to change the way schools are managed. The results highlight several inadequacies in the existing research for guiding policy and practice, the most notable of which is that many popular school-based prevention approaches have not been well studied to date. The study shows, however, that school-based prevention practices appear to be effective in reducing alcohol and drug use, dropout and nonattendance, and other conduct problems. The size of the average effect for each of the four outcomes was small and there was considerable heterogeneity across studies in the magnitude of effects, even within program type after adjusting for measured method and population differences. Non-cognitive-behavioral counseling, social work, and other therapeutic interventions show consistently negative effects, whereas self-control or social competency promotion instruction that makes use of cognitive-behavioral and behavioral instructional methods show consistently positive effects. Also effective are noninstructional cognitive-behavioral and behavioral methods programs. Environmentally focused interventions appear to be particularly effective for reducing delinquency and drug use.  相似文献

This paper explores the appropriate organisational structures for government lawyers. Professionals may require different arrangements than are applicable to others, particularly if professional skills and culture are to be maintained. These arrangements may include working within a professional group; line management by fellow professionalis of accepted professional competence; collegiate decision‐making processes. The same principles would seem to be applicable to other professional groups.  相似文献

Abstract: Canine biological specimens are often part of the physical evidence from crime scenes. Until now, there have been no validated canine‐specific forensic reagent kits available. A multiplex genotyping system, comprising 18 short tandem repeats (STRs) and a sex‐linked zinc finger locus for gender determination, was developed for generating population genetic data assessing the weight of canine forensic DNA profiles. Allele frequencies were estimated for 236 pedigreed and 431 mixed breed dogs residing in the U.S. Average random match probability is 1 in 2 × 1033 using the regional database and 1 in 4 × 1039 using the breed dataset. Each pedigreed population was genetically distinct and could be differentiated from the mixed breed dog population but genetic variation was not significantly correlated with geographic transition. Results herein support the use of the allele frequency data with the canine STR multiplex for conveying the significance of identity testing for forensic casework, parentage testing, and breed assignments.  相似文献

Research suggests that differences exist in the criminal justice ideology of Black and White Americans. For example, adult African Americans are more likely than their White counterparts to support criminal justice measures that address the root causes of crime. There has, however, been limited interest in exploring the criminal justice ideology of juveniles. Using survey data collected from 1,398 rural and suburban public high school students, the present study examined the influence of race on the criminal justice ideology of juveniles. The findings suggested that while Black teenagers are significantly more likely to hold a liberal crime control ideology and White teenagers are significantly more likely to hold a conservative ideology, confidence in the justice system to be fair strongly influences the beliefs of both groups.  相似文献

This study examined the ability of jury-eligible community members (N = 248) to detect internal validity threats in psychological science presented during a trial. Participants read a case summary in which an expert testified about a study that varied in internal validity (valid, missing control group, confound, and experimenter bias) and ecological validity (high, low). Ratings of expert evidence quality and expert credibility were higher for the valid versus missing control group versions only. Internal validity did not influence verdict or ratings of plaintiff credibility and no differences emerged as a function of ecological validity. Expert evidence quality, expert credibility, and plaintiff credibility were positively correlated with verdict. Implications for the scientific reasoning literature and for trials containing psychological science are discussed.  相似文献

Abstract:  Santeria and Palo Mayombe are syncretic religions created in the New World based upon African religious beliefs combined with Christianity. The main worship of Palo Mayombe involves religious receptacles that may contain earth, sticks, varied artifacts, and animal and human remains. Due to the use of human and nonhuman remains, discovery of these items often leads to involvement by the police due to a concern of homicide. We review in detail the medical examiner records of two of these ritualistic cases including the autopsy, anthropology, police, and investigators' reports. For the human remains, careful consideration of the context in which the remains were recovered, their state of preservation, and the associated artifacts (e.g., beads and mercury) are important in determining the appropriate level of forensic significance. Anthropological examination with particular attention to taphonomic characteristics also may help determine the origin and forensic significance.  相似文献

The effect of intimate partner violence (IPV) on mental health remains understudied in the Arab world. Using data from 608 ever-married women in rural Minya, Egypt who took part in the 2005 Egypt Demographic Health Survey (EDHS) and a 2012 follow-up survey, we assessed how a woman’s enabling resources and risk factors influenced the association of her exposure to IPV with her generalized anxiety. Results from multivariate regression models showed that proximity to natal kin, prior schooling, and engagement in market work 12 months before marriage had protective effects on generalized anxiety associated with IPV. Childhood abuse from mother also had a protective effect on this relationship. Similar abuse from the brother exacerbated the effects of anxiety when a woman was exposed to IPV. Empowerment programs can encourage women to attend school and engage in market or subsistence work, while suggesting strategies to improve the relationship of women with natal kin.  相似文献

Police agencies in the U.S. are currently facing a major legitimacy crisis resulting from a spate of high-profile use of force incidents, many involving minority citizens. Recent headlines emphasize that there is now a “war on cops” and that police officers are facing increasing levels of hostility and violence fueled by a growing anti-police sentiment. In the aftermath of events in Ferguson, Missouri in August 2014, some commentators claim that the number of police officers feloniously assaulted and killed in the line of duty has increased sharply. Using time series analysis of data from the Officer Down Memorial Page, we test whether events in Ferguson were associated with an increase in the number of police officers murdered in the line of duty. Our results provide no evidence for a “Ferguson Effect” on the number of U.S. police officers murdered in the line of duty as of March 2016.  相似文献

This study examines the relationships between negotiators' attitudes toward competitive and unethical tactics, their actual use of those tactics, and their subsequent perceptions of performance and reputation in two‐party, e‐mail‐based negotiations. The results indicate several predictors of competitive‐unethical behavior, including a negotiator's attitude toward competitive‐unethical tactics, early use of competitive‐unethical tactics, and the behavior of a negotiating counterpart. Furthermore, it was the perceived honesty of one's counterpart rather than the actual use of competitive‐unethical behaviors that was associated with a negotiator's perceptions of the collective or joint outcome. The implications of these findings are discussed, along with suggestions for future research.  相似文献

The Australian Federation is unique. Like all federations there is a division of powers between the various levels of government. However, unlike almost all other federations, the Australian Federation requires the cooperation of the states and the Commonwealth in order to achieve their institutional functions. This federal system can properly be described as 'cooperative federalism'. An understanding of the role of the states within this federal system suggests an urgent need for major constitutional reform at the state level.  相似文献
