This article applies strain theory to a high-risk sample of homeless street youth, with a particular focus upon labor market strain to predict violent and property crime and substance use. Data were collected through interviews with 200 street youth in a western Canadian city. Labor market strain was found to be related to the frequency of the youth's property, violent, and total crimes. Criminal peers and norms were also related to these crimes, as well as to drug use. Results also revealed a significant interaction effect between labor market strain and criminal norms predicting property, violent, and total crime. Interactions between strain and criminal peers, and external attributions also predicted property crime. Contrary to predictions, emotions were unrelated to crime and drug use. The results are discussed in light of Agnew's revised strain theory and suggestions are offered for future research on this topic. 相似文献

This study examines the relationship between vulnerability factors and recidivism by testing the hypothesis that first offenders who repeat delinquencies display more high-risk factors than those who do not repeat delinquencies. Four factors are identified which distinguish recidivists from nonrecidivists in a sample of first offenders matched by age and sex. Results are discussed from an epidemiological and early-intervention perspective.Data collected in 1980 were supported by the Research Associates, Clarke Institute of Psychiatry, University of Toronto, Toronto, Ontario, Canada.Received MSW from University of Michigan, 1972. Major research interests are juvenile delinquency and early intervention.Received Ph.D. in psychology from Washington University, St. Louis, Missouri, 1957.

Evaluation of technology transfer is an important part of the total transfer process. Sound results require a practical approach, which avoids use of the research model. The evaluation process is often expensive and time consuming. However, good evaluation will improve:motivation,knowledge,decisions, andaccountability. Evaluation must be based on use of reliable data. Technology transfer evaluation data can be classified — based on accuracy — aslow,medium, orhigh order — data. Evaluation problems can be designated — according to origin — as being related tonew information,human elements, orinstitutional structure. In each area, the more common evaluation problems can be solved with careful attention to detail. Technology transfer evaluation can be a complicated, but rewarding process. There is nosingle, correct way for Technology Transfer evaluation, but rather there is a wide variety of techniques which all have merit, depending on local circumstances. 相似文献

Survey data are presented and discussed as they relate to juvenile involvement in serious and violent delinquency. Juveniles
confined in two detention centers were administered self-report questionnaires (n=127). An integrated model that combines
social structural variables (i.e., neighborhood disorganization and strain) with social process variables (i.e., parental
control, social bond, and delinquent peer associations) was tested by way of path analysis. The data generally support the
integrated model, explaining as much as 44% of the variance. Two variables, delinquent peer associations and an overall social
bond indicator, directly and significantly predict serious delinquent behavior. Delinquent peer associations are significantly
related to neighborhood disorganization, while the social bond is significantly related to parental control and strain. Thus,
the data support a systems approach to explaining delinquent behavior, where social structural variables affect social process
variables.

Studies demonstrate that technology owned by US corporations is a highly valued commodity in the international arena. The Economic Espionage Act of 1996 was signed into law to help protect against misappropriations of that technology. This article chronicles some of the recent prosecutions under that law and some emerging issues of enforcement. 相似文献

Family aggression patterns and behavior problems of children, aged 6-12, recruited from shelters for battered women (shelter group) were contrasted with three comparison groups of currently nonviolent families: two-parent, single-mother, and homeless. Girls who had been exposed to recent interparental wife abuse were predicted to show more internalizing and externalizing behavior problems than similarly exposed boys, based on recent literature. Homeless and shelter mothers reported the highest rates of parent-child aggression. Shelter girls obtained significantly higher total, internalizing and externalizing behavior problem ratings than shelter boys, and than two-parent and single-mother girls. Shelter boys obtained significantly higher internalizing ratings than two-parent boys. Shelter and homeless children were rated as having equivalent levels of behaviour problems. Across all groups, mothers' psychological adjustment was a better predictor of daughters' adjustment than that of sons. The study concluded that the assumption that preadolescent girls have greater immunity to psychosocial risk is unfounded. 相似文献

Ronald Reagan has made revitalizing federalism a central componentof his domestic agenda. Although this goal has sometimes complementedhis other policy aims, this article focuses on cases where conflictshave arisen between the president's devolutionary goals andother primary objectives of his administration, such as deregulatingthe private sector and reducing domestic expenditures. Judgedfrom this perspective, policies supportive of federalism, asdefined by the president, have fared less well in his administration.After a series of brief case studies analyzing such policy decisions,the implications for the future of federalism are discussed. 相似文献
