Agnew's (1985) revised strain theory argues that delinquency results from the inability to escape legally from painful or aversive situations. There is much indirect support for the theory, with experimental and survey data indicating that delinquency is associated with a wide variety of aversive situations. The experimental data, however, are of questionable generalizability and the survey data are primarily cross sectional in nature, leaving unresolved the issue of causal direction. This study examines the relationship between environmental adversity and delinquency using longitudinal data from a nationally representative sample of adolescent boys. A distribution-free method (arbitrary generalized least squares) is used to estimate a covariance structure model depicting a reciprocal relationship between adversity and delinquency. The results support the revised strain theory: environmental adversity has a causal effect on delinquency, but delinquency does not have an effect on adversity.  相似文献

Unemployment insurance (UI) laws have recently come under considerable criticism for fostering employment disincentives. Imperfections in the experience rating tax schedule has been the primary causal factor behind most of these allegations. In particular, the insurance subsidies created by the tax schedule have been blamed for distorted labor markets and for increased layoffs.This article proposes that a property rights system be established for UI reserves which would enable a firm with an unemployment insurance reserve surplus to lend voluntarily to a firm in need of reserves. Such a system would allocate reserves more efficiently and eliminate some of the disincentives effects of the current unemployment insurance scheme. A property rights system would be a second best solution to perfecting the present unemployment insurance system and making it actuarially sound. However, assigning rights to UI reserves can be implemented without challenging the special interests of the politically dominant industries that have been responsible for maintaining the imperfections in the UI system for 50 years.  相似文献

Time/flow is a decisive variable when proposing public health interventions in jail populations and settings. The present paper argues that jail flow affects the types of public health interventions achievable in ways not acknowledged generally by public health/medical researchers. The paper explores how public health interventions vary among jail populations in terms of “flow” and how they are affected by a “period” effect. Interventions that will be effective and reach a substantial portion of the jail population are dependent upon the point in the jail processing process. In turn, the variables that affect the speed of population flow through the jail setting also influence who will be served by public health interventions.  相似文献

This case study illustrates the use of the date function on an automatic wristwatch to help identify a Vietnam War helicopter crash site. The location of a crash incident can sometimes be uncertain because of inadequate or inaccurate wartime records and the passage of time. Artifacts recovered from a prospective crash scene are regularly used to correlate the loss incident. In this case study, a recovered automatic watch displayed a date 2 days later than the reported loss incident. Although the date conflicts with the aircraft crash incident report, it is observed that a fully wound automatic watch continues to work for c. 2 days after movement of the watch ceases. Thus, the watch's date in fact correlates with the aircraft crash incident report. It is noted that automatic watches may also be used to date scenes of crime.  相似文献

In the era of re-entry, a great deal of attention has been paid to the ‘risk-need-responsivity’ model. Most attention to the utilization of services designed to meet need has focused on post-release behaviors. However, little attention has been paid to the pre-incarceration utilization of services that might influence receptivity to post-release utilization. Using constructs borrowed from health services utilization, the current paper examines the associations among CJ-involvement, social and health services utilization, and health status in a cohort of CJ-involved men living in the community. Results from the current cohort, combined with those of previous research, suggest that follow-through on services by released individuals’ remains problematic. Suggestions for future research and questions about the role of criminal justice agencies in improving follow-through are raised.  相似文献

An emerging parameter to define the effectiveness of new therapeutic agents in clinical trials,and by extension,for use in day-to-day clinical practice has been labeled mucosal healing.It has been hypothesized that complete healing of the intestinal mucosa in inflammatory bowel diseases should result in reduced disease complications,reduced hospitalization and reduced surgical treatment.By implication,the natural history of inflammatory bowel disease might then be altered. Measurement of mucosal healing,how...  相似文献

Successive Australian Defence Ministers have been frustrated and occasionally embarrassed by the quality of advice and information provided to them by the Defence organisation. Decades of reviews and reorganisations have failed to find solutions to the special difficulties that Defence faces in providing accurate, timely information and advice to ministers across the broad spectrum of their responsibilities. This article argues that there are multiple explanations for the concerns that are frequently expressed about its policy advisory capacity – most of which are inherent to Defence organisations around the world. While the Defence culture of secrecy is partly responsible, other factors such as the scale of Defence's operations, the multiple cultures that exist within it (military, civilian, and intelligence) that make coherence harder than in more homogenous departments, the long‐time horizons of defence planning as well as the high costs of procurement, must also be considered. The erosion of trust between the organisation and minister has been exacerbated by the intense scrutiny of the media that overburdens ministers and adds another layer of complexity to their role. As history shows, there are push and pull factors that continue to embroil ministers in the minutiae of defence difficulties, while the complexity and scale of operations will undoubtedly continue to impact on the timeliness of advice.  相似文献
