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

This study examines how programs sponsored through the National Institute of Standards and Technology's Manufacturing Extension
Partnership (MEP) have influenced the organization and delivery of industrial modernization services to small and medium-sized
manufacturers in regions in the United States. The study found that increased service coordination has occurred and that this,
in turn, has mostly improved the quality and comprehensiveness of assistance delivered to firms. But there are also some costs
and drawbacks associated with multi-partner service delivery approaches. The study identifies and examines best practices
that can help MEP centers increase the effectiveness of service coordination.
This paper draws upon research supported by the U.S. Department of Commerce, National Institute of Standards and Technology

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

Fatal Fentanyl Patch Misuse in a Hospitalized Patient with a Postmortem Increase in Fentanyl Blood Concentration 下载免费PDF全文

Opioid‐related mortality happens, even in healthcare settings. We describe serial postmortem fentanyl blood concentrations in a hospital inpatient who fatally abused transdermal fentanyl. This is a single‐patient case report. A 42‐year‐old man with lymphoma was started on transdermal fentanyl therapy while hospitalized for chronic abdominal pain. The patient was last seen awake 1.3 h prior to being found apneic and cyanotic. During the resuscitation attempt, a small square‐shaped film was removed from the patient's oropharynx. Femoral blood was collected 0.5 and 2 h postmortem, and the measured fentanyl concentration increased from 1.6 to 14 ng/mL. Study limitations include potential laboratory or collection errors and missing data. (i) Providers must be vigilant for signs of fentanyl patch abuse. (ii) Postmortem blood concentrations are not static postmortem, likely secondary to decreasing pH, increased aqueous solubility, and tissue redistribution, and are therefore unlikely to accurately represent antemortem blood concentrations. 相似文献

Ancestry and BMI Influences on Facial Soft Tissue Depths for A Cohort of Chinese and Caucasoid Women in Dunedin,New Zealand 下载免费PDF全文
Louisa J. Baillie B.H.Sc. B.F.A. Seyed Ali Mirijali M.S. Ph.D. Brian E. Niven B.Sc. M.Sc. Phil Blyth B.H.B. M.B.Ch.B. Ph.D. George J. Dias B.B.S. M.S. Ph.D. 《Journal of forensic sciences》2015,60(5):1146-1154
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
