An influential analysis by Przeworski and Limongi (1997) argued that a pro-democratic culture may help existing democracies survive, but political culture does not contribute to the process of democratization, which is entirely done by elites. We challenge this conclusion, arguing that it neglects the very nature of democratization. For (as Human Development theory argues), democratization is a liberating process that maximizes human freedom by establishing civil and political rights. Consequently, the aspect of political culture that is most relevant to democratization is mass aspirations for freedom – and if a given public emphasizes these values relatively strongly, democratization is likely to occur. To test this thesis, we use data from the Values Surveys, demonstrating that a specific component of postmaterialism (‘liberty aspirations’) had a major impact on the extent to which societies gained or lost freedom during the Third Wave of democratization. This effect holds up in tests of Granger causality, remaining strong when we control for prior levels of freedom. No other indicator, including GDP/capita and social capital, can explain away the impact of liberty aspirations on democratization. Mass liberty aspirations play a role in democratization that has been greatly underestimated. 相似文献

Will life expectancy in the United States rise or fall in this century? The implications of either scenario are far reaching. We contend that the rise of childhood obesity in the United States in the past three decades has been so dramatic that it will soon lead to higher than expected death rates at middle ages and a possible decline in life expectancy by midcentury. The most detrimental health and longevity effects will not be seen for decades--a phenomenon that cannot be detected by current methods used to forecast life expectancy or estimate the number of deaths currently attributable to obesity. This scenario contrasts sharply with the views of mathematical demographers who generate forecasts by relying on the assumption that the U.S. pattern of longevity will follow that of other longer lived nations and on the extrapolation of historical trends in life expectancy into the future. 相似文献

A theory is proposed that explains where interlocking corporate directorates should appear between sectors of an economy, where they should not appear, and the profitability of efficient corporate interlocking. Taking the sector of an economy as the unit of analysis, interlocking directorates are cast as strategically created constraints on those sectors of the economy most “problematic” for obtaining profits in a given industry of firms. The extent to which each sector of the American economy is problematic for obtaining profits in two-digit and four-digit manufacturing industries is estimated from research linking industry profits with the form of the pattern of relations defining the industry as a position in the network of dollar flow transactions given in the 1967 Input-Output Study for the United States. A two-stage process is described for sampling firms representative of large corporations involved in American manufacturing. Measures of alternative strategies for interlocking across sectors are described. Two classes of hypotheses are derived: (1) Firms in an industry should interlock with firms in some other sector in proportion to the extent to which the sector constrains the industry's profits. (2) Controlling for production and market differences, the ability of firms in an industry to obtain unusually high profits reflects their success in creating interlocks with those sectors most problematic for their industry's profits. 相似文献

The elevated rates of HIV/AIDS among inmates are due in part to the high concentration of incarcerated persons with behavioral risk factors for HIV infection. Corrections, public health, and community-based organizations should partner to take full advantage of the opportunity to maximize effectiveness and efficiency in addressing HIV/AIDS in inmate populations. The purpose of this study is to document issues inhibiting collaboration, service delivery, and multisite evaluation as identified by members of the U.S. Centers for Disease Control and Prevention/Health Resources and Services Administration Corrections Demonstration Project (CDP). Examining the barriers (and identifying ways to resolve them) is important in developing and maintaining successful programs that ultimately benefit HIV-infected inmates and the communities to which they return. 相似文献

An empirical study is described in which the feasibility of employing multidimensional scaling to obtain perceived measures of public projects is investigated. Data concerning eight possible muncipal projects were gathered from city officials and citizens of Kingston, Canada. Response problems are identified and the limitations for implementing the methods are discussed. 相似文献

An Investigation of Uncertainty and Sensitivity Analysis Techniques for Computer Models 总被引:12,自引:0,他引:12
Many different techniques have been proposed for performing uncertainty and sensitivity analyses on computer models for complex processes. The objective of the present study is to investigate the applicability of three widely used techniques to three computer models having large uncertainties and varying degrees of complexity in order to highlight some of the problem areas that must be addressed in actual applications. The following approaches to uncertainty and sensitivity analysis are considered: (1) response surface methodology based on input determined from a fractional factorial design; (2) Latin hypercube sampling with and without regression analysis; and (3) differential analysis. These techniques are investigated with respect to (1) ease of implementation, (2) flexibility, (3) estimation of the cumulative distribution function of the output, and (4) adaptability to different methods of sensitivity analysis. With respect to these criteria, the technique using Latin hypercube sampling and regression analysis had the best overall performance. The models used in the investigation are well documented, thus making it possible for researchers to make comparisons of other techniques with the results in this study. 相似文献

Discussions of the firm's relationships with its environment have usually concluded that the firm should make adaptive decisions to non-market areas, and proactive or strategic decisions in market areas. Predicating strategic responses upon the differences between market and non-market relationships is inappropriate and misleading, reduces the capacity of the firm to respond effectively to its environment, and distorts the process of environmental scanning. When the firm's relationships with its environment are examined as inter-organizational relationships, market and non-market relationships are structurally similar, and the same types of strategic responses can be selected for both areas. The strategic responses available to the firm in inter-organizational terms are: adaptation; pre-emption, co-optation; interpenetration; conflict and withdrawal. These processes and choices are structurally similar to traditional market related strategic options and can be used to respond to market and non-market factors. The manager scans the environment not only to identify opportunities for adaptation, but to identify groups which affect the integrity of the firm, the processes for interaction, the character of relationships, and occasions for strategic choice. The strategic decision process under a framework of inter-organizational transactions is illustrated by the cases of Sun Life Insurance Co., and the pulp and paper industry in Quebec. 相似文献
