Debates about the form and nature of changes in the management of public systems have for some time now been articulated under the theme of governance. All definitions of governance are related to the problems of securing convergence among a diversity of actors and organizations, of redistributing power in an organizational or social field characterized by a high level of heterogeneity and of gaining sufficient legitimacy to act in the name of the collectivity. This paper concentrates on the dynamics involved in the emergence of new governing capabilities in public systems. More precisely we study the implementation of regionalization policies in the health care field (in this case of Canada) conceived as one major attempt to renew the governance structures in a large public system. Our study draws on the comparative analysis of empirical regulation in three health regions as contrasted with three ideal type models of governance in regionalized systems. The first model is inspired by an economic approach to organizational behaviour and focuses on mandate‐giving, execution and control. The second model is based on a political interpretation of behaviours and focuses on negotiation processes between actors. Finally, the third model is based on the theory of deliberation as well as the institutional school of policy analysis and focuses on direct public participation in public affairs. Evidence for this article is primarily derived from interviews with key informants and documentary analysis. Our analysis shows that none of the three models is sufficient in itself to grant regional structures the authority and legitimacy they need to create added value in terms of regulation that could ensure their survival. Regional Boards are thus forced by environmental constraints to conceive and implement original mixes of these models. The two predominant logics in regional action are inspired by the first two models although the last one also has an influence. Overall, our study also suggests that the implementation of new sources of governing authorities in a public system is rather fragile because of dependence on existing institutions. Clearly, the attempt to modify the dynamics of governance in a given system must be conceived as a political exercise and not just as a technical problem consisting of the rational adjustment of policy instruments.  相似文献

Although a growing literature documents the benefits of industry–university research centers, most centers experience a significant amount of turnover among their industrial members. In order to gain a better understanding of this phenomenon, the current study attempts to identify factors that predict member renewal (DV). Questionnaire data were collected from industrial respondents (N=249) participating in 39 centers funded by the NSF IUCRC program. Structural, member benefits and administrative process variables were used to predict the dependent variable. Logistic regression analyses identified three significant predictors: professional networking benefits, research relevance and administrative operations. Implications of these findings for public policy, cooperative research management and future research are discussed.  相似文献

Preparation of a ytterbium‐tagged gunshot residue (GSR) reference standard for scanning electron microscopy and energy dispersive X‐ray spectroscopic (SEM‐EDS) microanalysis is reported. Two different chemical markers, ytterbium and neodymium, were evaluated by spiking the primers of 38 Special ammunition cartridges (no propellant, no projectile) and discharging them onto 12.7 mm diameter aluminum SEM pin stubs. Following SEM‐EDS microanalysis, the majority of tri‐component particles containing lead, barium, and antimony (PbBaSb) were successfully tagged with the chemical marker. Results demonstrate a primer spiked with 0.75% weight percent of ytterbium nitrate affords PbBaSb particles characteristic of GSR with a ytterbium inclusion efficiency of between 77% and 100%. Reproducibility of the method was verified, and durability of the ytterbium‐tagged tri‐component particles under repeated SEM‐EDS analysis was also tested. The ytterbium‐tagged PbBaSb particles impart synthetic traceability to a GSR reference standard and are suitable for analysis alongside case work samples, as a positive control for quality assurance purposes.  相似文献

Objectives

Examine the long-term effects of two childhood universal prevention programs on adolescent delinquency, substance use, and antisocial behavior.

Methods

The cluster randomized controlled trial involved 56 schools and 1,675 children in Zurich, Switzerland. Two evidence-based interventions, namely the social-emotional skills program Promoting Alternative Thinking Strategies (PATHS) and the cognitive-behavioral parenting program Triple P, were implemented during the first two years of primary school, at ages 7 and 8 years. Outcomes were measured at ages 13 and 15 years, and included youth self-reports and teacher assessments. Multilevel models were used to account for the clustered nature of the interventions. Effects were estimated with the inclusion of baseline covariates.

Results

Across 13 outcomes related to delinquency, substance use, and antisocial behavior at ages 13 and 15 years, only two non-negligible effects were found. The first was a reduced prevalence of police contacts in the PATHS condition [effect size (ES)?=??0.225). The second was a difference in competent conflict resolution skills in the combined PATHS?+?Triple P condition compared to the context (ES?=?0.259), but in the unexpected direction: participants in the combined treatment appeared to be less competent than their control group peers. All other effects were either statistically non-significant or negligible in size (i.e., ES?<?|0.200|).

Conclusions

Even “evidence-based” interventions may have few long-term effects on delinquency, substance use, and antisocial behavior. Our findings add to the small literature on the long-term effectiveness of early universal prevention in field settings.
