Cities across America look for management strategies useful for accomplishing their responsibilities and programs. While some cities include privatization strategies in their management portfolios, others do not, and the underlying reasons are not readily apparent. This study seeks to gain some insight into this disparity through several questions: Why do some cities use more privatization than others? Are privatization levels higher in fiscally healthy or fiscally stressed cities? Where are the cities that use privatization located? This study attributes municipal privatization levels in medium-sized cities, in part, to degree of wealth, fiscal stress, and location. The findings suggest that privatization levels are higher in wealthy, fiscally healthy, suburban cities. 相似文献

In the last two decades, many states established rail promotion programs in an effort to limit the contraction of their railroad networks. Now federal funds for rail projects are nearly exhausted, and states must decide whether to expand considerably their levels of internal funding for short line investments. Such a decision requires a careful articulation of policy goals, combined with sound cost-benefit techniques. Research shows, however, that states often fail to evaluate the full range of costs and benefits when considering rail investments. Instead, the economic development benefits of local rail service frequently are overstated, while the potential for rail investments to meet broader transportation planning needs is neglected. This paper evaluates the rationale behind state intervention in the rail industry, discusses the tendency of states to focus on economic development to the exclusion of other benefit categories, and presents summary results from an analysis of an investment project in North Carolina. The paper suggests that state funding for rail projects is more likely to be justified based on intermodal substitution benefits generated by local rail service, rather than the railroads' potential to increase jobs. 相似文献

There is no doubt that medical semiotics are having a revival at the moment. Different aspects of yesterday's and today's interest in semiotics and in the historical interpretation of signs of disease in the context of theory and history of medicine can be illuminated: their deciphering as the history of the sign in medicine by historic science, their overestimation by philosophy during the Age of Enlightenment, their reduction to a phenomenology of medicine and natural science during the first half of the 19th century and their transformation to medical diagnostics since the middle of the 19th century and recently even their functionalization as methodical instrument within the history of science. The following will show the change in meaning of medical semiotics. Modern development and especially the transition to medicine, based on natural science, will be emphasized. 相似文献

The characterization of the products of international cooperation as public goods has been severely challenged, undermining a central pillar of theories of international cooperation. I review the criticism of public goods assumptions, identifying the need to account for both exclusion and rival consumption in international cooperative arrangements. Drawing on the recent debate of states as relative versus absolute gains maximizers, I offer a characterization of international cooperative arrangements as discriminatory clubs. I develop a refined relative gains model, which focuses on relative net gains, and apply it to a hypothetical situation to illustrate its usefulness in predicting patterns of exclusion and distribution in international trade. 相似文献

The Campania was a fertile area, with a growing population during the eleventh and twelfth centuries, and was economically more advanced than most of the rest of southern Italy. This essay examines the impact of the Norman conquest of the south upon this region, with special reference to the settlement pattern and the aristocracy. It concludes that the role of incastellamento in changing the pattern of settlement was relatively limited, and the extensive incastellamento of the Montecassino lands (a product of Norman pressure upon the abbey) cannot be taken as typical. Furthermore, while the Norman conquest led to colonisation by French aristocrats, this did not entirely displace existing Lombard families, and widespread intermarriage led to a blurring of the distinction between Lombards and Normans. The impact of political crises during the twelfth century was also more limited than might be supposed, and continuity rather than change characterised the nobility of the Norman period. 相似文献
