Much of the attention surrounding local climate protection in the United States is associated with two networks: ICLEI Local Governments for Sustainability's Cities for Climate Protection and the U.S. Conference of Mayors’ Climate Protection Agreement (MCPA). However, the impact of these networks on member‐city actions has not been clearly established. This paper examines whether, and to what extent, participation in climate networks leads to the implementation of greenhouse gas (GHG)‐reducing policies, above and beyond what would have been done in their absence. To account for the possibility that cities which join climate networks are systematically different from those that do not and control for self‐selection induced bias, three statistical techniques—propensity score matching, Heckman full information maximum likelihood, and instrumental variables—are employed to estimate the “treatment effect” of participation. Results suggest that impact is network specific: ICLEI membership causes small to moderate increases in cities’ GHG‐relevant activity, whereas the MCPA has no such effect. The characteristics of each network are evaluated in light of these findings.  相似文献

This article examines the application of organizational reputation to public administration. Organizational reputation is defined as a set of beliefs about an organization’s capacities, intentions, history, and mission that are embedded in a network of multiple audiences. The authors assert that the way in which organizational reputations are formed and subsequently cultivated is fundamental to understanding the role of public administration in a democracy. A review of the basic assumptions and empirical work on organizational reputation in the public sector identifies a series of stylized facts that extends our understanding of the functioning of public agencies. In particular, the authors examine the relationship between organizational reputation and bureaucratic autonomy.  相似文献

With the large and growing number of persons with mental illnesses under probation supervision, a form of specialized probation called specialized mental health caseload (SMHC) has been implemented. This study explores the effectiveness of a prototypic SMHC implemented statewide. A quasi-experimental design was used to compare criminal justice, mental health, and community engagement outcomes among three caseloads: a newly established SMHC supervising no more than 30 clients per officer (N = 1367); an established SMHC supervising roughly 50 clients per officer (N = 495); and a traditional caseload of clients receiving mental health treatment and supervised by officers with average caseloads of over 130 clients (N = 5453). Using a mixed methods approach, we found that the SMHC was implemented with high adherence to fidelity, and comparisons based on different caseload samples generally support the effectiveness of the specialized mental health caseload, particularly on criminal justice outcomes. Future studies using random assignment are needed to examine the connection among mental health symptoms, compliance with treatment and probation supervision, and recidivism.  相似文献

Trans‐municipal networks (TMNs) have reshaped the landscape around local government action on global climate policy. Past research has focused on why cities join TMNs and the impact that membership has on local action. This study considers a potential reverse effect: namely, that cities' membership choices position them to influence TMNs' overall priorities. In considering this, we emphasize the role of network administrative organizations (NAOs) and posit that the multiple climate‐related networks, which share members and operate in overlapping geographic and issue spaces, are bound together as part of a meta‐network. We utilize social network analysis and data on membership in four climate‐related TMNs to examine the factors that shape how cities can influence meta‐network priorities. We find that cities with local vulnerabilities tend to be located in network positions that enable them to influence the meta‐network's overall priorities.  相似文献

The climate of school classrooms, shaped by a combination of teacher practices and peer processes, is an important determinant for children's psychosocial functioning and is a primary factor affecting bullying and victimization. Given that there are relatively few theoretically-grounded and validated assessment tools designed to measure the social climate of classrooms, our research team developed an observation tool through participatory action research (PAR). This article details how the assessment tool was designed and preliminarily validated in 18 third-, fourth-, and fifth-grade classrooms in a large urban public school district. The goals of this study are to illustrate the feasibility of a PAR paradigm in measurement development, ascertain the psychometric properties of the assessment tool, and determine associations with different indices of classroom levels of relational and physical aggression.  相似文献

States in the same region are bound together by the ways in which the world imagines them as a collective. One distinguishing feature of post-Cold War regionalism is its outward orientation – the importance of the external dimension of regional cooperation. By and large, though, existing analysis of regional institutional development in the Global South does not explicitly conceptualise and theorise collective image consciousness and management. This paper works to address this conceptual gap. Making use of two cases of regional image crisis – post-1980s Africa and post-1997 Southeast Asia – it draws out two primary logics of regional image consciousness: the logic of influence and the logic of resources. A region’s ‘brand’ with respect to (dys)function and international norm (non-)compliance matters to regional actors because it affects the region’s political influence in international arenas and the region’s ability to attract resources from donors and investors.  相似文献

The efficiency of conventional polarized light microscopy (PLM) methods for analyzing synthetic fiber evidence analyses is improved. Historically, using PLM for fiber identification relied on measuring refractive index. This prior PLM technology is reliable, but it is not efficient. Most fibers are optically anisotropic, having two principal refractive index values, N(High) and N(Low). When the fiber is mounted in intermediate refractive index medium, efficiency is improved by observing the change in contrast while the polarized light’s vector is rotated relative to the fiber’s axis. Minimum contrast occurs when the refractive indices of the mounting medium and fiber are equal. This angle of equality is determined by orienting the fiber’s highest refractive index parallel to the polarized light’s electric field vector, rotating the fiber or polarizing element, observing minimum contrast and measuring the angle of equality. This method is rapid, reduces remounting fibers in different mounting media and provides a quantitative measure for fiber comparisons.  相似文献

The presence of methadone was investigated in 24-h perspiration samples obtained from patients receiving daily maintenance doses of the drug. The samples were collected from the axillary region. The concentrations measured by radioimmunoassay ranged from 8.3 ng/cm2 per 24 h up to 25.3 ng/cm2 per 24 h. The concentrations determined by RIA are the sum of methadone and its metabolites. The presence of the drug in the perspiration samples were also revealed by GC/MS.  相似文献
