We consider an extension of Tullock's (1980) N-player contest under which prize valuations may vary across players. We show that the pure-strategy equilibrium of this contest is unique. We also establish the following results: rent dissipation increases, individual winning probabilities decrease, and individual spending either increases or decreases with the addition of a player. 相似文献

This study examined the cultural and developmental significance of maternal and paternal parenting processes (closeness, support, monitoring, communication, conflict, and peer approval) for measures of anxiety and depression symptoms in adolescents from Hungary, the Netherlands, Switzerland, and the United States (N=6,935). Across all cultural contexts, measures of maternal and paternal support and conflict were most consistently associated with measures of internalizing behaviors. Few differences were observed in the importance of individual parenting processes for anxiety or depression symptoms across cultures. Additionally, with the exception of maternal conflict for anxiety and depression symptoms and paternal closeness for depression symptoms, none of the parenting process dimensions differed in importance for internalizing behaviors across developmental periods (middle versus late adolescence). The investigation provides evidence of great similarity in developmental processes, both across cultural contexts and developmental periods.

Private-public partnerships are increasingly seen as an important mechanism for improving community health. Despite their popularity, traditional evaluations of these efforts have produced negative or mixed results. This is often attributed to weak interventions or an insufficient period of time to observe an impact. This study examines two additional possibilities--the need for a well-articulated shared vision and the governance and management capabilities of the partnership itself. We conducted a midstream process evaluation of twenty-five community partnerships associated with the Community Care Network (CCN) Demonstration Program. We examined how the roles of a common shared vision, strong governance, and effective management influence a partnership's ability to achieve its objectives. The findings, based on both qualitative and quantitative analyses, underscore the importance of membership organizations' perceived benefits and costs of participation and management capabilities to the partnership's progress toward a vision. Based on the qualitative data, six key governance and management characteristics are identified that separate the top performing partnerships from the lowest performing ones. We explore the implications of this research for future evaluations of public-private community health partnerships. 相似文献

The article deals with the problem of suicidal behavior in the Ukraine military environment and gives an example of the successful prevention approach. The model of prevention is based on (1) education of the responsible officers, (2) training of the representatives of the most vulnerable risk groups, and (3) follow-up procedures based on distribution of pocket books for soldiers, educational booklets, and sets of helpful materials for officers. One of the main conclusions is that the prevention activity must be organized as a continuum of actions, seminars, consultations, and materials distribution. 相似文献

The 4- Aminophenol (4-AP) colorimetric test is a fast, easy-to-use, and cost-effective presumptive assay of cannabis plant material producing different chromophores with THC-rich cannabis (blue color) and with CBD-rich cannabis (pink color). The main drawback of the 4-AP test is a brief observation window where the color rapidly changes to black, limiting the utility of the test. We now report for the first time, the identification of the product chromophores between 4-AP and CBD/THC as well as propose an explanation and a solution for the color degradation of the chromophores. The identification of the chromophores is provided by spectroscopic (UV–Vis), chromatography, and mass spectrometry (TLC and LC-QToF-MS). Oxidation of excess 4-AP (Reagent A) in the presence of NaOH (Reagent B) produces the black color observed for the previously reported 4-AP tests and reported in the literature. The adjustment of reactants concentrations and volumes of 4-AP:THC/CBD to a 1:1 ratio significantly reduces the black oxidation by-product and increases the observation window up to 2 h instead of the previously reported 5–10 min. For the first time, mass spectrometry and chromatography confirmed that the reaction of THC and CBD with 4-AP produced chromophores with m/z (M + H) = 420, consistent with proposed indophenol structures. The TLC method developed confirmed the separation between CBD and THC chromophores. The specificity of the test is also reported, showing false positive results for the presence of THC (blue color) for samples of thyme and oregano. LDA and SIMCA models showed that the optimized 4-AP procedure performs better than the previously reported 4-AP color test. 相似文献

Although many EU‐countries have reduced corporate taxes in the recent years, there is still a substantial variance between the 12 oldest EU‐member states. This contribution revisits this variation and analyses the determinants of corporate tax reforms and their magnitude from a perspective which is new in two respects: First, we combine logistic panel regression and fsQCA analysis allowing for an integration of qualitative assessments of tax reforms in the QCA analysis. This adds to the existing studies on tax reform which almost exclusively rely on regression techniques. Second, we focus on the time period 1998‐2011 where we expect tax competition to be especially intense. The results of our analyses confirm the major impact of tax competition on national corporate tax policies. This relationship dominates the regression analyses as well as the fsQCA. Furthermore, our findings allow nuancing the existing results on the influence of institutional constraints and partisan politics. 相似文献

In light of the reforms undertaken for the sake of the Euro, the article revisits the concept authoritarian liberalism that was introduced in 1933 by the German public law scholar Hermann Heller. This notion seeks to capture the liaison between the ‘strong state’ and economic liberalism. The article suggests that this notion can be fruitfully used to designate the new governance of economic and monetary union. It argues, particularly, that it makes sense to speak of an authoritarian style of governance even if the latter does not wear vestiges of outright repression. Two different faces of authoritarian liberalism can be distinguished: one that looks more towards authoritarianism and another one that views authoritarian rule as a managerial strategy that is good for the economy. The article then speculates whether the EU has been, indeed, successful because it shifts between the two. Disturbingly, there may be something deeply as well as more accidentally authoritarian about European integration. 相似文献
