Explaining Cooperation: How Resource Interdependence, Goal Congruence, and Trust Affect Joint Actions in Policy Implementation 总被引:1,自引:0,他引:1
A perennial problem when political decisions are to be implementedis how to make authorities work together. Previous researchshows that resource interdependence, goal congruence, and mutualtrust increase interorganizational cooperation. In this article,it is argued that interaction effects must also be consideredin order to fully understand how these variables affect cooperation.The study is based on 203 dyads of Swedish Public EmploymentService offices and municipalities in 2003. I find that mutualtrust is necessary if goal congruence is to increase cooperationbetween these agencies. Furthermore, mutual trust only has apositive effect if organizations have similar objectives. However,trust is not required for resource interdependence to affectcooperation, and the effect of trust is not dependent on theorganizations' mutual dependence. The results imply that trustand goal congruence must exist simultaneously in order to promotejoint actions. Thus, if a management strategy aimed at increasingcooperation only focuses on the organizations' objectives orthe level of trust between them, it will fail. An importantlesson for future research is that including interaction termsin the analysis improves our understanding of interorganizationalcooperation. 相似文献

In order to assess the effectiveness of government programs designed to reduce disparities in the health care minority groups receive relative to the majority white population, a proper statistical measure should be used. This article proposes a measure of and its accompanying graph, which is readily interpretable and is not affected by the number of minority subgroups examined. 相似文献

This study examined the emergence of affect specificity in infancy. In this study, infants received verbal and facial signals of 2 different, negatively valenced emotions (fear and sadness) as well as neutral affect via a television monitor to determine if they could make qualitative distinctions among emotions of the same valence. Twenty 12‐ to 14‐month‐olds and 20 16‐ to 18‐month‐olds were examined. Results suggested that younger infants showed no evidence of referential specificity, as they responded similarly to both the target and distracter toys, and showed no evidence of affect specificity, showing no difference in play between affect conditions. Older infants, in contrast, showed evidence both of referential and affect specificity. With respect to affect specificity, 16‐ to 18‐month‐olds touched the target toy less in the fear condition than in the sad condition and showed a larger proportion of negative facial expressions in the sad condition versus the fear condition. These findings suggest a developmental emergence after 15 months of age for affect specificity in relating emotional messages to objects. 相似文献

This study examined the processes that underlie the association between trait expressiveness and marital satisfaction. A total of 168 newlywed couples participated in a four‐wave, 13‐year longitudinal study of marriage. Cross‐sectional and longitudinal path analyses suggested that expressiveness promotes satisfaction by leading spouses to engage in affectionate behavior and by leading them to idealize their partner. Expressive people formed idealized images of their partner because they brought out the best in their partner's behavior and because they interpreted their partner's behavior in a favorable light. The study extends previous research by showing that the benefits of trait expressiveness extend into the second decade of marriage and by providing a plausible explanation of the connections between trait expressiveness and marital satisfaction. 相似文献

Consider a website and the surfers visiting its pages. A typical issue of interest, for example while monitoring an advertising campaign, concerns whether a specific page has been designed successfully, i.e. is able to attract surfers or address them to other pages within the site. We assume that the surfing behaviour is fully described by the transition probabilities from one page to another, so that a clickstream (sequence of consecutively visited pages) can be viewed as a finite-state-space Markov chain. We then implement a variety of hierarchical prior distributions on the multivariate logits of the transition probabilities and define, for each page, a content effect and a link effect. The former measures the attractiveness of the page due to its contents, while the latter signals its ability to suggest further interesting links within the site. Moreover, we define an additional effect, representing overall page success, which incorporates both effects previously described. Using WinBUGS, we provide estimates and credible intervals for each of the above effects and rank pages accordingly. 相似文献

Recently, we developed a GIS-Integrated Integral Risk Index (IRI) to assess human health risks in areas with presence of environmental pollutants. Contaminants were previously ranked by applying a self-organizing map (SOM) to their characteristics of persistence, bioaccumulation, and toxicity in order to obtain the Hazard Index (HI). In the present study, the original IRI was substantially improved by allowing the entrance of probabilistic data. A neuroprobabilistic HI was developed by combining SOM and Monte Carlo analysis. In general terms, the deterministic and probabilistic HIs followed a similar pattern: polychlorinated biphenyls (PCBs) and light polycyclic aromatic hydrocarbons (PAHs) were the pollutants showing the highest and lowest values of HI, respectively. However, the bioaccumulation value of heavy metals notably increased after considering a probability density function to explain the bioaccumulation factor. To check its applicability, a case study was investigated. The probabilistic integral risk was calculated in the chemical/petrochemical industrial area of Tarragona (Catalonia, Spain), where an environmental program has been carried out since 2002. The risk change between 2002 and 2005 was evaluated on the basis of probabilistic data of the levels of various pollutants in soils. The results indicated that the risk of the chemicals under study did not follow a homogeneous tendency. However, the current levels of pollution do not mean a relevant source of health risks for the local population. Moreover, the neuroprobabilistic HI seems to be an adequate tool to be taken into account in risk assessment processes. 相似文献

Drug treatment courts (DTCs), an alternative to traditional criminal courts, provide an innovative way to legally process some drug offenders. The origin and recent growth of the drug court system in the USA can be explained as an unintended consequence of a failing 'war on drugs'. In this article, we discuss the spread of adult DTCs throughout the USA, the main components of drug courts, controversies surrounding DTCs, and some criticisms of drug courts. We summarize the recent evaluations of adult DTCs, and highlight various DTC factors that have been found to reduce individual drug use and criminal activity. We also offer suggestions for future research on DTCs and conclude with policy recommendations. 相似文献

Some observations on the history of large philanthropic foundations in Britain and the United States
Martin Bulmer 《Voluntas: International Journal of Voluntary and Nonprofit Organizations》1995,6(3):275-291
Large philanthropic foundations such as those which first developed in the United States in the late nineteenth and early
twentieth century had four characteristics: (a) the aim of contributing to the public good; (b) applying science and scientific
method to human affairs, interpreting science broadly; (c) using great wealth to pursue these purposes; and (d) seeking public
recognition of their charitable status in doing so. Between 1870 and 1930 the large foundation emerged as a major social institution,
and under the influence of their officers began to be major patrons of applied social science for public policy purposes.
Critics of foundations have charged that they were private bodies without external accountability; they were secretive, undemocratic,
unrepresentative and indeed pillars of the ruling class. Nevertheless, foundations have exercised a disproportionate influence
upon public policy research and have sought to apply fundamental knowledge to tackling social problems. They represent the
institutionalisation of knowledge-based social engineering. 相似文献
