Abstract This article traces the history of one community's efforts to coordinate services to address family violence. The current mazeof organizations in communities is overwhelming to the professionals who work in them, the political leaders who authorize them, the foundations and United Ways who fund them, and, most assuredly, to the persons for whom the various organizations were established. A review of the literature on coordination and collaboration is included as well as a discussion of leadership challenges during the various stages in the evolutionary process to provide confidential, culturally sensitive, comprehensive, accountable, and user-friendly community social service systems. 相似文献

AbstractThere is no doubt that knowledge management is now a very dominant theme in modern enterprises. To survive and compete in a knowledge-based economy, companies must learn to manage and sustain their intellectual assets. As a number of practitioners have noted, human resources play an important role in the transition process to the knowledge-based economy. This transition process is characterized by participant-driven integrative teamwork for dealing with various tasks and issues in organizations. This article presents a case study of the development of human resources in the context of knowledge management, which is based on systems thinking, exploring the process of problematization. It is based on a Foucauldian approach to expose the social relationship of power, knowledge and subjectivization in the problem-solving practice. 相似文献

AbstractDuring 2009, the Hilton M. Briggs Library, South Dakota State University, went live with MetaLib, a federated search engine from Ex Libris. This paper presents the implementation process, addresses resource accessibility issues, and suggests a number of resources that can be consulted about these issues. Readers can apply similar strategies to projects involving federated search systems, as many implementation projects involve the same basic considerations presented here. The author did not find any studies specifically focused on configurations of MetaLib resources, so this content should be singularly useful. 相似文献

ABSTRACT In this paper we study the classification of the generalized mixtures of two or three exponential distributions, in the ILR and DLR classes, and consequently in the IFR and DFR classes. We apply these results to classify the aging of the series and parallel systems, in accord with some common bivariate exponential models of their components. 相似文献

Data from two Maryland AFDC quality control samples (n=2376) are joined with data from two surveys of local administrative practices to examine administrative correlates of error. Less error exists among cases processed by agencies that: 1) use checklists to simplify agency procedures, 2) use follow-up controls in conjunction with tickler files, 3) have in-house training to deal with earned income procedures, 4) provide training on reducing earned income errors, and 5) have less staff turnover. Surprisingly, the findings show client error to be more influenced by administrative practices than agency error, suggesting the distinction between the two may be misleading. 相似文献

Large initial investment in advanced manufacturing systems (AMS) makes it imperative to develop economic justification methods. Once the new system has been properly justified, a critical issue facing the firm is the optimal timing of the installation in an industry. In this paper we use a game-theoretic model by which the optimal timing of the investments in AMSs is analysed. The existence of timing equilibria is demonstrated and simple decision rules of optimal strategy are provided. Economic interpretations of the decision rules are subsequently made clear. Finally, illustrative examples are used to demonstrate the correctness and usefulness of the analysis. 相似文献

A probabilistic method is presented to evaluate the economic value of fire monitoring by closed circuit TV camera in petroleum refineries. The proposed model is restricted to the analysis of risk reduction in an area where fires can be caused either by pump failure or by failure of valves and lines. The benefits come from reducing the time during which the fire grows undetected. Fire growth and expected values of losses are analyzed by a Markov model that includes five phases: (1) active undetected growth, (2) detection, (3) fire growth at the beginning of the firemen's intervention, (4) fire control, and (5) fire extinction. The results (e.g., the expected net present value of the investment) show that the proposed monitoring investment is attractive for an illustrative example. 相似文献
