Governance theory raises conceptual and theoretical questions about the coordination of complex social systems and the evolving role of the state within that process. A central aspect of the governance debate focuses on the ability of national governments to address salient social issues. This article examines the British Labour governments' attempts to facilitate cross-departmental inter-organizational collaboration within Whitehall in an attempt to develop innovative responses to seemingly intractable social problems. The government's desire and strategy to increase its capacity to orchestrate 'joined-up' government can be interpreted as both an acceptance and a response to the challenges of modern governance. The article locates the structural, procedural and cultural responses to this challenge within the theoretical and analytical framework of governance theory. It concludes by suggesting that meaningful change in the way public policy is designed and implemented may well demand a more deep seated reappraisal of the structure of Whitehall and the dominant values of the British political elite than is currently anticipated.  相似文献

While some commentators believe that the Enron and Arthur Andersen affair that came to light in 2001 is responsible for the demise of multidisciplinary practices (MDPs), the notion of law firms engaging in MDPs lost most of its momentum during the American Bar Association (ABA) debate of 1999 and 2000. Enron and Andersen weakened whatever support remained for MDPs after the ABA defeat, during which MDP opponents raised legitimate concerns. But Enron and Andersen did not derail all models in which law firms successfully provide nonlegal services. In fact, the law-related services ancillary business model (as referred to by the ABA's Commission on Multidisciplinary Practice) is much more relevant post-Enron. Ancillary businesses, or subsidiary businesses as they are referred to at the authors' law firm of Bingham McCutchen LLP, are not MDPs. When structured and managed in compliance with fundamental principles and regulations, subsidiary businesses give progressive law firms the ability to deliver a comprehensive bundle of integrated services in response to client needs .  相似文献

While information regarding the doctoral programs in any discipline is of obvious and considerable relevance both to those in the discipline and to those seeking access to the best possible sites for graduate training, our knowledge about the quality of doctoral programs continues to be based on little more than speculation and highly ambiguous measures of institutional or departmental prestige. This study attempts to fill this gap for those who have special interests in the related fields of deviance, criminology, and criminal justice by ranking the thirty-six most significant doctoral programs in the nation by means of data derived from the Social Science Citation Index. Perhaps the most striking of our findings—and certainly to us the most distressing finding—is that those departments ranked by our measures as being the highest quality are consistently those which exist within the broader structure of departments of sociology. Given our firm conviction that the discipline of criminology is far, far more than that aspect of it which is closely related to issues of substantive significance to the field of sociology, we can only speculate that those in leadership positions in the growing number of independent schools or departments of criminology or criminal justice are not meeting their obligations to the discipline whose vitality and prospects depend so heavily on the quality of their judgment.  相似文献

Levels of magnesium, potassium, sodium and calcium in post-mortem vitreous humour from human controls, fire fatalities and drowning victims have been determined. The effects of time-related internal changes, external environmental parameters and different causes of death are evaluated. Despite the positive correlation and marked increase of potassium and, to a lesser extent, of magnesium and calcium with the length of the post-mortem interval, individual biological variability severely limits the usefulness of predictions of post-mortem interval based on electrolyte metal data. At best, there is only a 2/3 chance of a prediction being within 12 h of the true value. Vitreous humour metal concentrations are affected by external influences, such as the elevated temperatures of fires which increase the rate of release of intracellular magnesium and potassium. In cases where drowning is suspected, establishment or exclusion of this cause of death is not possible on the basis of vitreous humour electrolyte metal data because of possible post-immersion diffusion across the permeable membrane of the eyeball. It appears, however, that magnesium in salt-water cases and sodium in fresh-water cases are related, albeit erratically, to the length of the immersion period.  相似文献

Purpose

Naturally-occurring social support is underutilized in interventions with former prisoners with substance use disorders. This paper proposes a conceptual framework followed by a program model to inform the development of naturally-occurring social support interventions with former prisoners with substance use disorders.

Methods

We reviewed all published social support interventions designed for former prisoners and people with substance use disorders over a ten year period. Building on the implications of this review, empirical literature, professional experience, and theory, we propose a conceptual framework for naturally-occurring social support programs.

Results

Few published programs exist that actively incorporate social support providers into the program model. Of these, even fewer use naturally-occurring support. Expanding on gaps in theory and program approaches, the conceptual model posits that it is the appropriate match of support needs and provision that reinforces emotions, cognitions, and behaviors, that in turn, promote adaptive outcomes.

Conclusions

With mounting pressure to identify interventions that will reduce high re-incarceration rates, this paper draws attention to a neglected, potentially effective, and low cost resource - naturally-occurring social support. The described program, Support Matters, illustrates how social support interventions can be used with former prisoners to promote reduced relapse to substance misuse and crime.  相似文献

PURPOSE: Whether lifetime abstainer's antisocial behavior are maladjusted or well-adjusted is unresolved. The aim of this study was to compare abstainers (defined as persons with no lifetime use of alcohol and other drugs and non-engagement in antisocial or delinquent behavior) with non-abstainers across a range of sociodemographic and mental health characteristics in the United States. METHODS: Data were derived from the National Epidemiologic Survey on Alcohol and Related Conditions, a nationally representative sample of U.S. adults. Structured psychiatric interviews (N = 43,093) using the Alcohol Use Disorder and Associated Disabilities Interview Schedule - DSM-IV version (AUDADIS-IV) were completed by trained lay interviewers between 2001 and 2002. RESULTS: The prevalence of abstaining was 11%. Abstainers were significantly more likely to be female, Asian and African-American, born outside the U.S., and less likely to be unemployed. Multivariate logistic regression analyses revealed that abstainers were significantly less likely to evidence lifetime mood, anxiety, or personality disorder compared to non-abstainers. CONCLUSIONS: Findings indicate that abstainers are not maladapted and are comparatively more functional than non-abstainers.  相似文献

Though the poverty encountered by many rural youth encompasses numerous developmental challenges and substantially increases the chances for educational problems, the school context is central to promoting and constraining their development. Therefore, the purpose of this study was to investigate the relationship of school characteristics and schooling experiences to the educational achievement and aspirations of youth from high-poverty rural communities. Differences in the relationship of school characteristics and schooling experiences to the educational outcomes of students from high- versus low-poverty rural communities were also examined. Participants included 6,247 high school students from 43 low-poverty and 21 high-poverty rural communities. Approximately 51.7% of participants were female and the sample was racially/ethnically diverse (66.4% White, 9.2% African American, 8.1% Hispanic/Latino(a), 4.4% Native American, and 11.8% Multiracial). After controlling for student and family background, school characteristics (e.g., lower student–teacher ratio) were predictive of achievement for rural youth from high-poverty communities. Schooling experiences (e.g., positive perceptions of their ability, a sense of school valuing and belonging, and preparation for postsecondary education) were predictive of educational achievement and aspirations for rural youth from high- and low-poverty communities. Overall, the study highlights unique ways schools can positively shape the educational outcomes for rural youth despite community poverty.  相似文献
