This paper offers graphic illustration of so-called “valence” models of candidates responding to their perceptions of voter location in a two-party system. Models by Groseclose and others show how the combination of candidate uncertainty about the median voter location, nonzero candidate valence, and policy motivated candidates leads to departures from the median voter prediction. With one policy dimension, either there exists an equilibrium where the candidates do not converge to the median (or any other common position) or there exists no equilibrium. We offer illustrations based on plausible conditions. Under some conditions we show an equilibrium where candidates locate at separate policy positions. Under others, we illustrate the absence of equilibrium.  相似文献

The long‐term budget prospects of the United States are grim. Projected spending greatly exceeds projected revenue over the next few decades. Projected growth of health care spending accounts for more than all of the anticipated gap. Without action to narrow the gap, accumulating deficits will drive up the ratio of debt to GDP. Interest payments will rise correspondingly. At some point, domestic and foreign holders of U.S. debt will come to doubt the capacity of the government to service this debt. At that point, they will demand sharply higher interest rates. The combination of increasing debt and rising interest rates will cause debt service costs to explode. What follows would be some combination of collapsing investment, declining production, debt default, and inflation—in brief, a calamitous mess. That such a mess will occur is certain if budget deficits as large as those currently anticipated are realized. Precisely when is impossible to forecast accurately.  相似文献

Given that parenting practices have been linked to suicidal behavior in adolescence, examining the moderating effect of parenting styles on suicidal behavior early in development could offer potential insight into possible buffers as well as directions for suicide prevention and intervention later in adolescence. Hence, the moderating effects of parenting styles, including authoritarian, permissive, and features of authoritative parenting, on depressed and aggressive children’s suicidal behavior, including ideation and attempts, were evaluated with young children (N = 172; 72% male, 28% female) ranging from 6 to 12 years of age. African American (69%) and Caucasian (31%) children admitted for acute psychiatric inpatient care completed standardized measures of suicidal behavior, depressive symptoms, and proactive and reaction aggression. Their parents also completed standardized measures of parental distress and parenting style. Hierarchical regression analyses revealed that, while statistically controlling for age and gender, children who endorsed more depressive symptoms or reactive aggression reported more current and past suicidal behavior than children who endorsed fewer depressive or aggressive symptoms. The significant positive relationship observed between depressive symptoms and childhood suicidal behavior, however, was attenuated by parental use of authoritarian parenting practices for African-American and older children but not for younger and Caucasian children. The ethnic/racial difference observed for the buffering effect of authoritarian parenting practices offers potential theoretical and clinical implications for conceptualizing the moderating effects of parenting styles on African-American and Caucasian children’s suicidal behavior.  相似文献

Existing typological frameworks do not adequately categorize terrorist groups by their operational characteristics. We propose a new framework which compares terrorist groups to business firms. In our framework, terrorist groups are mapped on two axes: centralization of resources and centralization of operations. We separate terrorist groups into four typologies echoing familiar business arrangements: Hierarchy, Venture Capital, Franchise, and Brand. Responses to each typology are briefly sketched out. We conclude by analyzing the changes in Al Qaeda over the last two decades in the context of our framework. We close by proposing appropriate policy responses to combat Al Qaeda in light of its current Brand typology.  相似文献

This article compares the design and implementation of density for benefit agreements (DBAs), a form of density “bonusing” in Toronto and Vancouver. The cities identify many of the same priorities for benefits secured from developers, but in practice they prioritize widely different benefits. By comparing practice in Toronto and Vancouver, this article demonstrates how institutional differences and the decentralization of policy decision‐making in major cities can affect urban planning decision‐making.  相似文献

The purpose of this article is to provide an example of recent public administration reform in Afghanistan. In 2003, the Afghan Ministry of Public Health (MoPH) established the Basic Package of Health Services (BPHS) and other health services. To date, service delivery has been conducted largely by NGOs, funded by the main international donors, and managed by the Grant and Contracts Management Unit (GCMU) of the MoPH. Despite these advancements, Afghanistan continues to face significant challenges in health service provision and policy. In 2009, the GCMU was restructured into the Health Economics and Financing Directorate (HEFD), which broadened the scope of the Unit to conduct important economic analyses. This article examines the MoPH's role in health financing as a developing institution engaged in applied health economics and policy analysis. This development will allow the MoPH to build evidence for policy-making and further establish its stewardship role in the health sector.  相似文献
