Concentrations of unemployment and crime are promoting a slow crisis in the lives of unskilled young men, and obstruct the successful re-integration and resettlement of offenders. At the same time, criminal justice system programmes for offenders are seeking a new balance between treatment approaches and the creation of opportunities. In this article the author reflects on the policy frameworks which give rise to these approaches, and considers the danger that criminal justice systems may place emphasis on diverting people from crime without directing them towards opportunities for re-integration. The author considers the needs of offenders in relation to housing and employment in particular.  相似文献

新公共行政学在公共行政领域具有重要的地位,对公共行政理论与实务的发展,产生了重要而持续的影响。作为对20世纪60年代美国动荡不安的社会现状的回应,新公共行政学者们对主流行政学研究方法进行了质疑与批判,并对当时的主流价值提出抗衡性观点。新公共行政学的理论意涵经由三次明诺布鲁克会议(1968年、1988年和2008年)而延续,尽管三次会议的背景与主题各不相同。然而,在其发展过程中,新公共行政的影响力仍然无法扩展至整个学科领域。  相似文献

This study measured and assessed facial soft tissue depths (FSTDs) in adult female Chinese and New Zealand (NZ) Europeans (Caucasoids). Ultrasound was used to obtain depths at nine landmarks on 108 healthy subjects (51 Chinese, 57 NZ European), erect positioned, of same age group (18–29 years). Height and weight were also recorded. Statistical analysis focused on comparison of tissue depth between the two ancestry groups and the influence of Body Mass Index (BMI) (kg/m2). Results showed mean depth differences at Supra M2 and Infra M2 landmarks significantly greater for Chinese than Caucasoid women for all three BMI Classes (BMI <20, 20 ≤ BMI < 25, 25 ≤ BMI < 30), even BMI <20. For both groups BMI positively correlated with FSTD values at all landmarks except Labrale superius. This study enabled ancestry and BMI influence on FSTDs to be observed and compared for two distinct groups. Results add to knowledge about facial tissue depth variation.  相似文献

Brief case histories involving incest were presented to police officers, child welfare workers, and community mental health practitioners in a rural area in Canada. Intervention priorities involving “treatment versus punishment” were assessed across the three professional groups for each specific case vignette. Attitudes were assessed on three factors: perpetrator mentally ill rather than criminal, view regarding treatment of victims and mothers, and support for court mandated treatment. Police and community mental health practitioners had significantly different attitudes as to whether perpetrators of child sexual abuse should be viewed more as criminals or as mentally disturbed. Both mental health and child welfare staff differed significantly from police with a less punitive view towards victims and their mothers. All three profressional groups showed no difference in their modest endorsement of the use of mandated treatment by the courts. Gender was not found to influence response to case vignettes.  相似文献

Mexico's crime-ridden southern frontier has become a veritable third U.S. border, as a constant flow of Central Americans and others cross into Mexico, often en route to the United States. As the number of unlawful migrants surges, their characteristics are changing: recent apprehensions include nationals of Caribbean, Middle Eastern, and Asian nations, and foreigners linked to terrorism are using Mexico as a thoroughfare to the United States. Mexico's immigration department is hindered by a number of factors in stanching this flow, and Mexican officials have only begun to publicly recognize the severity of the problem. Washington, too, must wake up to the security threat posed by Mexico's soft underbelly.  相似文献

Wildland fires constitute a major crisis in American environmental policy, a crisis created by a longstanding policy failure. This article explores the political processes that generated and reinforced this policy failure over time. The concepts of bounded rationality, punctuated equilibria, and self- reinforcing mechanisms are applied to study the evolution of American wildfire policy between 1905 and the present. This study finds that a self-defeating wildfire suppression policy was established in the period 1905 through 1911, and subsequently reinforced for more than five decades. This policy did not include a complementary program to counteract the gradual accumulation of flammable organic materials (fuels) that occurred in many ecosystems when fires were suppressed. The resulting fuel accumulations have greatly increased the risk of damaging, high-intensity wildfires in a range of American wildlands. A combination of fire suppression and fuel reduction programs will be needed to manage this risk in the future.  相似文献
