The dissemination of social program innovations that have been demonstrated to be effective through rigorous evaluation is an important issue. The classical dissemination framework emphasizes the position that programs implemented with fidelity to the original model are most likely to produce the positive outcomes demonstrated in the model's evaluation phase. However, critics suggest that local programs that are extensively modified are more likely to meet local goals and, therefore, are more likely to be sustained within the organization. The present research examined the implementation, effectiveness, and routinization of seven innovations replicated in a nationwide sample of organizations. The innovations were diverse in both content and implementing context and were located in a variety of sites, including schools, courts, prisons, police departments, and social service agencies. The results suggest that the innovations were replicated with acceptable levels of fidelity to the disseminated program models, and that higher-fidelity implementations tended to be more effective than those implemented with lower fidelity. The implications of the findings for social program dissemination policy are discussed and the authors propose an expansion of Berman's contingency model of innovation dissemination.  相似文献

Anfang Februar 2012 unterzeichneten die 17 Euro-Staaten den Vertrag über die Einrichtung eines permanenten Europ?ischen Stabilit?tsmechanismus ("ESM-Vertrag"). Einen Monat sp?ter wurde von 25 der 27 EU-Mitgliedstaaten der Vertrag über Stabilit?t, Koordinierung und Steuerung in der Wirtschafts- und W?hrungsunion ("VSKS") zum Abschluss gebracht. Beide Vertr?ge sind Teil des Krisenbew?ltigungsprogramms in der Union, stehen aber au?erhalb des EU-Vertragswerks. Aufgrund der Ausgestaltung als rein zwischenstaatliche Vereinbarungen werfen die beiden Vertr?ge hinsichtlich ihres Verh?ltnisses zu und ihrer Vereinbarkeit mit dem Recht der Europ?ischen Union einige interessante Fragen auf, die der vorliegende Beitrag n?her untersuchen will.  相似文献

To explain the existence of large lobbying groups, Olsonproposes a `by-product theory': large lobbies are by-productsof industry associations that operate as monopolists inprivate goods markets. This paper explicitly formulatesOlson's by-product theory of lobby funding and examines itsefficiency as a funding method. Lobbying efficiency isenhanced by the association's ability to price-discriminate.Price discrimination, in turn, is facilitated by theassociation's superior knowledge of its members'characteristics. The paper also examines the relationshipbetween lobby strength and industry size, as well as thequestion of `who exploits whom' under by-product lobbying.  相似文献

The diagnosis of death as a result of starvation is established on anthropological measurements, visual appearance of the deceased on external and internal examination, microscopic analysis, laboratory testing, and exclusion of other causes of death. Herein, we present our findings on a case of 95‐year‐old man who died of starvation. After the diagnosis of starvation was established by traditional forensic medicine methods, we have conducted retrospective segmental analysis of stable carbon (δ13C) and nitrogen (δ15N) isotope ratios in hair sample. This method reveals periods of starvation through decrease in δ13C and increase in δ15N along the strand of hair. Our analysis revealed the decrease of 0.6 ‰ in δ13C during the last 10–12 weeks prior to death, similar as reported in other investigations. Also, a decrease of 0.7 ‰ in δ15N during the last 8–10 weeks prior to death was determined that was different than observed in previous studies.  相似文献
