Local public services are produced through various overlapping jurisdictions. This study examines how the issuance of municipal general obligation bonds is affected by the tax policies of overlapping local governments. The findings challenge the hypothesis that the shared tax base would be overused in a common-pool resource scenario. Instead, the empirical results show that the issuance of general obligation bonds is more likely in jurisdictions where counties and school districts make more intensive use of the property tax. These findings highlight the importance of the signals local governments receive from their overlapping neighbors regarding voters’ demand for additional public spending. 相似文献

This paper suggests the future direction in which public affairs practice is developing and advances a number of propositions about public affairs and political systems which provide the context in which public affairs practitioners operate. The paper examines the changing nature of the political systems in which public affairs functions and argues that, by inference, public affairs practice is culturally specific. The paper explores these contextual issues from both a European and a global perspective. The paper argues that an understanding of public affairs should be recognised as an essential element on management teaching syllabi and laments the fact that this is far from the case.

Some commentators claim that white Americans put prejudice behind them when evaluating presidential candidates in 2008. Previous
research examining whether white racism hurts black candidates has yielded mixed results. Fortunately, the presidential candidacy
of Barack Obama provides an opportunity to examine more rigorously whether prejudice disadvantages black candidates. I also
make use of an innovation in the measurement of racial stereotypes in the 2008 American National Election Studies survey,
which yields higher levels of reporting of racial stereotypes among white respondents. I find that negative stereotypes about
blacks significantly eroded white support for Barack Obama. Further, racial stereotypes do not predict support for previous
Democratic presidential candidates or current prominent Democrats, indicating that white voters punished Obama for his race
rather than his party affiliation. Finally, prejudice had a particularly large impact on the voting decisions of Independents
and a substantial impact on Democrats but very little influence on Republicans. 相似文献

Rejection sensitivity (RS) refers to the tendency to anxiously expect, readily perceive, and overreact to experiences of possible rejection. RS is a clear risk factor for psychological maladaptation during early adolescence. However, there is growing evidence of significant heterogeneity in the psychological correlates of RS. To investigate when RS poses the greatest psychological risk during early adolescence, this study examines mutual best friendship involvement (or lack thereof) and the best friends?? RS as potential moderators of the associations between RS and psychological difficulties. Participants were 150 7th grade students (58 boys; M age = 13.05 years) who nominated their best friends, and reported on their RS, social anxiety, and self-esteem. Results from a series of hierarchical multiple regression analyses indicated that mutual best friendship involvement and best friends?? RS were both significant moderators when fear of negative evaluation (a type of social anxiety) served as the dependent variable. The association between RS and fear of negative evaluation was stronger for adolescents without mutual best friends than adolescents with mutual best friends. In addition, the association between RS and fear of negative evaluation was the strongest for adolescents whose best friends were highly rejection sensitive (relative to adolescents whose best friends were moderately or low in RS). Findings highlight the importance of considering best friendships in studies of RS and strongly suggest that, although having mutual best friendships may be protective for rejection sensitive adolescents, having a rejection sensitive best friend may exacerbate difficulties. The significance of friends in the lives of rejection sensitive adolescents is discussed as well as possible applied implications of the findings and study limitations. 相似文献

Abstract: DNA mixtures with two or more contributors are a prevalent form of biological evidence. Mixture interpretation is complicated by the possibility of different genotype combinations that can explain the short tandem repeat (STR) data. Current human review simplifies this interpretation by applying thresholds to qualitatively treat STR data peaks as all‐or‐none events and assigning allele pairs equal likelihood. Computer review, however, can work instead with all the quantitative data to preserve more identification information. The present study examined the extent to which quantitative computer interpretation could elicit more identification information than human review from the same adjudicated two‐person mixture data. The base 10 logarithm of a DNA match statistic is a standard information measure that permits such a comparison. On eight mixtures having two unknown contributors, we found that quantitative computer interpretation gave an average information increase of 6.24 log units (min = 2.32, max = 10.49) over qualitative human review. On eight other mixtures with a known victim reference and one unknown contributor, quantitative interpretation averaged a 4.67 log factor increase (min = 1.00, max = 11.31) over qualitative review. This study provides a general treatment of DNA interpretation methods (including mixtures) that encompasses both quantitative and qualitative review. Validation methods are introduced that can assess the efficacy and reproducibility of any DNA interpretation method. An in‐depth case example highlights 10 reasons (at 10 different loci) why quantitative probability modeling preserves more identification information than qualitative threshold methods. The results validate TrueAllele® DNA mixture interpretation and establish a significant information improvement over human review. 相似文献

Abstract The literature on intelligence little describes or comparatively analyzes the intelligence services of insurgent groups. This article partially fills the gap by assessing the intelligence activities of FARC – the Revolutionary Armed Forces of Colombia. FARC intelligence displays similarities to, as well as sharp differences from, the intelligence activities of other insurgent groups and established states. Like FARC as a whole, FARC intelligence is decentralized. Its strength is its focus on tactical military intelligence. Collection on strategic political issues, analysis, and counterintelligence are relatively weak. FARC's intelligence weaknesses limit its prospects for strategic success and its intelligence-related vulnerabilities offer the Colombian government opportunities to exploit. 相似文献
