Political-economic classics of different schools agreed that capitalism inherently and inevitably leads to a decline of market principles. We analyze indicators of liberalization policies for 21 OECD-countries in five economic and social policy fields and demonstrate that western industrialized countries are subject of a convergent trend towards market-creating policies??in stark contrast to the theoretical expectations of several political economy authors. At the latest during the first half of the eighties, the western democracies entered a new phase of economic liberalization, which continues up to the present. A methodological implication of our findings suggests that the methods of causal analysis of convergent liberalization policies may not be the same as those who have been applied for the analysis of development and consolidation of the varieties of capitalism in the postwar era.  相似文献

In this note we present a variant of the improved algebraic method (IAM) using a duality analysis to solve linear programming (LP) problems where more insights to the method are presented. When the coordinates of all vertices are computed, any feasible point can be expressed as a linear combination of the vertices. The objective function is expressed as a weighted sum of its evaluation at the feasible vertices and the optimal point is associated with the highest/lowest coefficient of the weighted sum.  相似文献

Abstract

In this installment of Serial conversations, MIT cataloger Benjamin Abrahamse talks with Fran§oise Pell©, head of the International ISSN Centre, about the role played by International Standard Serial Numbers (ISSN) in facilitating the identification and collocation of serial publications in a networked environment.  相似文献

Numerous studies suggest spirituality and subjective well-being (SWB) are positively associated. However, critics argue that popular spirituality instruments—including the Daily Spiritual Experiences Scale (DSES)—contain items that conflate religiosity/spirituality (R/S), prosociality and SWB. Advocates of the DSES retort that, despite this concern, the available evidence confirms a single underlying factor. The current paper evaluates the DSES’s development, factor structure, reliability and convergent and predictive validity using a community sample. Despite the full DSES scale’s excellent internal reliability, two related factors—theism and civility—are identified. Both scales are reliable and converge meaningfully with related R/S measures. As expected, given previous findings, the full DSES scale predicts higher SWB yet the two subscales display divergent associations. This finding offers new insights into the DSES and raises questions about the claimed belief-as-benefit effect.  相似文献

The Rate of Return on Investment in Wine   总被引:1,自引:0,他引:1  
Is wine an investment alternative to stocks and bonds? First, we review prior studies regarding the pecuniary rate of return to wine and other alternatives to financial assets. Next, we calculate the rate of return to holding red Bordeaux wine from 1986 to 1996 using a repeat‐sale regression. Finally, we contrast the financial performance of wine, both on an aggregate basis and for various portfolios, to that of other asset classes. We conclude that wine does not yield greater returns than financial assets, especially when the volatility of returns and transaction costs are taken into account.  相似文献

Millions of workers suffer from upper extremity (musculoskeletal) disorders. Many of these workers are predisposed to upper extremity musculoskeletal disorders because of early exposure to ergonomic risks as students. Computer usage for four or more hours remains the greatest risk for upper extremity musculoskeletal disorders for workers and students alike. Developing preventative methods to reduce student exposure, and thus protect future workers from upper extremity musculoskeletal disorders later in life, requires an appropriate measure for upper extremity musculoskeletal disorder prevalence and related limitations for student functioning. Item response theory analysis was used to evaluate and further develop a upper extremity functioning scale for the student role.  相似文献

We consider a life testing situation in which systems are subject to failure from independent competing risks. Following a failure, immediate (stage-1) procedures are used in an attempt to reach a definitive diagnosis. If these procedures fail to result in a diagnosis, this phenomenon is called masking. Stage-2 procedures, such as failure analysis or autopsy, provide definitive diagnosis for a sample of the masked cases. We show how stage-1 and stage-2 information can be combined to provide statistical inference about (a) survival functions of the individual risks, (b) the proportions of failures associated with individual risks and (c) probability, for a specified masked case, that each of the masked competing risks is responsible for the failure. Our development is based on parametric distributional assumptions and the special case for which the failure times for the competing risks have a Weibull distribution is discussed in detail.  相似文献

Crafting the budget is an annual process that Congress and the administration use to define the national policy agenda. It is a massive undertaking to decide how more than two trillion dollars is spent by the federal government. Over 20 percent of the budget is used for health care. The budget is a political document that defines the priorities of the federal government and directly influences overall health policy. Its construction deserves to be followed and influenced by physicians to ensure the health of the public.  相似文献
