During the last decade, numerous local government reforms influenced by New Public Management (NPM) ideology have taken place throughout Scandinavia. Based on case studies in three Scandinavian municipalities, the article discusses the effects of introducing strategic political management on the role of councillors. We observe a conflict between NPM‐inspired management ideas and a deeply institutionalised, traditional view of councillors as representatives of the citizens, advocating peoples’ interest, defining needs, setting priorities and controlling implementation. Across national and local contexts, councillors find that the reforms challenge their traditional role and have strengthened administrative influence. Historical institutionalism seems to be a fruitful concept to understand resistance towards taking on new role models.  相似文献

Vacuum metal deposition (VMD) involves the thermal evaporation of metal (silver) in a vacuum, resulting in a uniform layer being deposited on the specimen being treated. This paper examines the use of silver on dark fabrics, thus offering a simpler operation and more obvious colouration to that of the traditional use of gold and zinc metals which must be evaporated separately. The aim of this study was to investigate the effect of fabric type, donor, mark age and method of fingermark deposition on the quality of marks visualised using silver VMD. This was achieved by collecting fingermark deposits from fifteen donors, of both sexes and various ages, by a grab or a press method. Four different fabrics: satin, polyester, polycotton and cotton were studied over a 10 day timeline of 1, 2, 3, 4, 5, 6, 7, 14, 21 and 28 + days. It was found that satin and polyester gave the most positive results, with polyester often producing excellent ridge detail. Cotton and polycotton were less successful with no ridge detail being observed. The donors also had an observable effect on the results obtained probably due to variations in secretions produced or pressures applied during specimen collection. The age of the mark or the method of mark deposition had little influence on the results obtained. Silver VMD is a viable process for visualising marks on certain dark fabrics and has the advantage over gold/zinc VMD in that the marks visualised are light in colour which contrasts well against the dark background.  相似文献

Abstract

Previous estimates of the size and composition of the U.S. homeless population have been based on cross‐sectional survey methodologies. National enumeration efforts have yielded point‐prevalence estimates ranging from 0.11 to 0.25 percent of the population. This study reports data from shelter databases in Philadelphia and New York City that record identifiers for all persons admitted and so make possible unduplicated counts of users.

Unduplicated counts of shelter users yield annual rates for 1992 of about 1 percent for both cities and rates near 3 percent over three years in Philadelphia (1990–92) and over five years (1988–92) in New York City. The annual rates are three times greater than rates documented by point‐prevalence studies. Shelter bed turnover rates are reported, as are average monthly first admission and readmission counts over a two‐year period. Implications for future research and public policy are discussed.  相似文献

Based on analysis of Brazilian-Spanish cooperation in Latin America, this article aims to contribute to the discussion on whether South–South Cooperation (SSC) represents an alternative model with specific and differentiated objectives, or if it largely reproduces the constraints and interests traditionally associated with the North–South model, but with new institutions and actors. We start by analysing the main criticisms levelled at cooperation in the literature, emphasising the identification, review and comparison of the mechanisms of domination and dependency that derive from the bilateral and multilateral practices of traditional development cooperation. We then construct a synthetic dependency index to measure the ability of Spain and Brazil – as representative cases of North–South Cooperation (NSC) and SSC with Latin America – to influence the foreign trade, investment and foreign policy decisions of aid recipients, and to empirically contrast the lower level of verticality that much of the available literature assumes about SSC schemes. The empirical analysis suggests significant differences between NSC and SSC in terms of their ability to reproduce dependency patterns and validate the discourse that tends to identify the latter as an alternative cooperation model.  相似文献

The several Jewish communities discussed are those in Kaifengand in Shanghai. The presence of the earlier and the later settlersraises several questions. How did the Kaifeng Jews retain theiridentity as Jews for several centuries while becoming part ofChinese society? Whereas the initial group of arrivals in Shanghaiconsisted of traders, the twentieth-century groups were refugees.Why were large numbers of Central European Jews able to landin Shanghai when most countries closed their doors to them?  相似文献
