The size of the Pareto set in the issue space of spatialvoting models is a function of the tax prices that voters arecharged. When all voters pay Lindahl prices for all goods, thePareto set collapses to a single point. The Pareto set can beenlarged by altering tax shares so they are further fromLindahl prices, and can be reduced by moving toward Lindahlpricing. A smaller Pareto set moves voters closer to consensuson issues, so reduces political decisionmaking costs and makesthe political system more stable. 相似文献

This article provides an overview of recent trends in imprisonment rates in America and introduces the articles in this issue of The Review of Policy Research. Incarceration rates have increased by more than 500 percent since the early 1970s and have now reached a rate of almost 700, higher than anywhere else in the world. The impact has been particularly hard on racial minorities, especially women (whose incarceration rate went from around 8 in 1975 to 59 in 2001). The “war on drugs” has been one of the main reasons behind the increases in imprisonment, along with the more general “get tough on crime” movement that began in the late 1970s. The articles in this issue center around how this recent trend in incarceration impacts the entire society, but especially poor communities. Several of the articles focus on race, age and gender as important variables, in addition to the tendency of the parole system to sort of “recycle” released prisoners back into the prison system. 相似文献

The International Monetary Fund: A review of the recent evidence 总被引:1,自引:1,他引:0
A review of recent quantitative studies on the International Monetary Fund reveals that much of the conventional wisdom is
incorrect. Recent studies have demonstrated a new degree of methodological rigor, have drawn more heavily upon insights from
political science, and have asked a number of new questions. We review studies of participation in IMF programs, design of
IMF conditionality, implementation and enforcement of IMF conditions, conventional program effects and catalytic effects.
At every stage, we find substantial evidence of the influence of major IMF shareholders, of the Fund’s own organizational
imperatives, and of domestic politics within borrowing countries. We conclude that very little is known with certainty about
the effects of IMF lending, but that a great deal has been learned about the mechanics of IMF programs that will have to be
taken into account in order to obtain unbiased estimates of those effects.

The existing literature on economic sanctions has rarely addressed the key question of comparing the effectiveness of positive and negative sanctions. It is the contention of this study that positive sanctions can potentially be more effective, even in cases where contentious "high politics" issues are being negotiated, relations between the states concerned are tense and militarized, and the state being targeted with sanctions has substantial military power. This assertion will be tested in a set of case studies drawn from German-Polish and German-Russian/Soviet relations from the nineteenth century to the present. It will be shown that positive sanctions can be used effectively, both as "specific" sanctions to influence a target state on one particular issue, and as "general" sanctions, which aim to change the state's behavior as a whole in a more slow and subtle process. 相似文献

Dermestid beetles (Dermestes maculatus De Geer 1774) are small carrion insects characterized by a rounded or oval-shaped body and white abdomen with black markings. Given their natural propensity to consume soft tissue throughout various stages of decomposition, biological anthropologists have sought to use dermestids as a forensic processing method in addition to traditional chemical tissue removal techniques. Although useful, most of the existing academic literature regarding the upkeep of dermestid colonies for skeletal remains processing either lack specificity or are outdated. Additionally, nonacademic sources that contain information regarding dermestid maintenance are often disjointed, resulting in a difficulty to replicate habitat construction and ideal environmental conditions. Therefore, this technical note presents recommendations for anthropologists interested in establishing and maintaining a D. maculatus population. These recommendations are based on our experiences using several dermestid colonies to process five unembalmed human heads, procured from an anatomical gift company for a larger study on gunshot trauma. Aspects of the dermestids’ environment that are crucial for the management of a healthy colony include the type of bedding, food, water, and containment method used, in addition to maintaining appropriate temperature ranges (24–27°C) and humidity levels (35–73%). Although habitat construction and dermestid maintenance involve materials that are relatively inexpensive and readily available, setting up and maintaining a D. maculatus colony can be laborious and time consuming and should only be undertaken when the volume of casework is such that this investment would be offset. 相似文献

The current cross-sectional study investigated the links between various dimensions of organized activity involvement and
depressive symptoms, loneliness, and peer victimization in an ethnically and economically diverse sample of adolescents (N = 152; 58% female). Results indicate that adolescents who were involved in organized activities for more years also reported
lower levels of loneliness. There was evidence of diminishing returns when adolescents were very highly involved in organized
activities; those who were either under- or over-involved reported the highest levels of depressive symptoms. Conversely,
findings indicate that adolescents who participated in a narrow or wide range of activity contexts reported the lowest levels
of depressive symptoms. In addition, results suggested that the relation between organized activity involvement and adjustment
differs among adolescents from diverse ethnic and socioeconomic backgrounds. Findings from the current study also underscore
the importance of considering multiple indices of activity involvement when assessing its association with adjustment.
