Right-wing politicians sometimes can implement policies that left-wing politicians cannot, and vice versa. Contemporary wisdom has it that only Nixon could have gone to China. We develop a model to explain this phenomenon. A policy issue could depend on information, on which every one could potentially agree on policy, or on values, on which agreement is impossible. Politicians, who value both reelection and policy outcomes, realize the nature of the issue, whereas voters do not. Only a right-wing president can credibly signal the desirability of a left-wing course of action. The Nixon paradox can hold then if citizens vote retrospectively on the issue. 相似文献

Fluorescence Imaging of Posterior Spiracles from Second and Third Instars of Forensically Important Chrysomya rufifacies (Diptera: Calliphoridae), 下载免费PDF全文
Danielle Flores M.S. Amy L. Miller M.S. Angelique Showman M.S. Caitlyn Tobita Lori M. N. Shimoda B.S. Carl Sung B.S. Alexander J. Stokes Ph.D. Jeffrey K. Tomberlin Ph.D. David O. Carter Ph.D. Helen Turner Ph.D. 《Journal of forensic sciences》2016,61(6):1578-1587
Entomological protocols for aging blowfly (Diptera: Calliphoridae) larvae to estimate the time of colonization (TOC) are commonly used to assist in death investigations. While the methodologies for analyzing fly larvae differ, most rely on light microscopy, genetic analysis, or, more rarely, electron microscopy. This pilot study sought to improve resolution of larval stage in the forensically important blowfly Chrysomya rufifacies using high‐content fluorescence microscopy and biochemical measures of developmental marker proteins. We established fixation and mounting protocols, defined a set of measurable morphometric criteria and captured developmental transitions of 2nd instar to 3rd instar using both fluorescence microscopy and anti‐ecdysone receptor Western blot analysis. The data show that these instars can be distinguished on the basis of robust, nonbleaching, autofluorescence of larval posterior spiracles. High‐content imaging techniques using confocal microscopy, combined with morphometric and biochemical techniques, may therefore aid forensic entomologists in estimating TOC. 相似文献

A key problem in trying to manage diverse societies is finding social policies that will be acceptable to all individuals and groups. Studies suggest that this problem may not be as intractable as is often believed, since people's acceptance of policies is shaped to an important degree by the fairness of the procedures used by authorities to make policy. When policies are fairly made, they gain widespread support, even among those who may feel that the consequences of the policy for them or their group are undesirable or even unfair. These findings support an optimistic view of the ability of authorities to manage diverse societies. On the other hand, research suggests that the ability of procedural justice to bridge differences among individuals and groups may not be equally strong under all conditions. People's willingness to accept policies is more influenced by procedural justice judgments when they identify with the society that the authorities represent and view them as representing a group of which they are members. They are less influenced by procedural justice judgments when they identify more strongly with subgroups than with society and/or view the authorities as representatives of a group to which they do not belong. 相似文献

There is widespread criticism of the behaviour of junior officials in post-communist Europe where they are often accused of treating citizens unfairly and soliciting presents or bribes to solve citizens' problems. To get the perspective of officials themselves we interviewed 1307 junior officials and state employees in Ukraine, Bulgaria, Slovakia and the Czech Republic. This paper focuses on their willingness to accept gifts from clients, their confessions to having done so, and the factors that lead some officials to accept gifts while others do not – factors such as occupational bargaining power and the (related) frequency of offers from clients, economic pressures, national and institutional cultures, fear of punishment, and moral perspectives on charging clients for favours. Economic pressures make officials more inclined to feel that they 'could not afford to refuse' gifts, but this motivation is only weakly related to actual behaviour. Occupational bargaining power and the frequency of offers from clients make them more likely to 'welcome' gifts or accept them 'out of politeness'– and these less excusable motivations are more strongly related to actual gift-taking. 相似文献

We propose a framework for understanding how the Internet has affected the U.S. political news market. The framework is driven by the lower cost of production for online news and consumers' tendency to seek out media that conform to their own beliefs. The framework predicts that consumers of Internet news sources should hold more extreme political views and be interested in more diverse political issues than those who solely consume mainstream television news. We test these predictions using two large datasets with questions about news exposure and political views. Generally speaking, we find that consumers of generally left‐of‐center (right‐of‐center) cable news sources who combine their cable news viewing with online sources are more liberal (conservative) than those who do not. We also find that those who use online news content are more likely than those who consume only television news content to be interested in niche political issues. 相似文献

TrueAllele® Genotype Identification on DNA Mixtures Containing up to Five Unknown Contributors 下载免费PDF全文
Mark W. Perlin Ph.D. M.D. Jennifer M. Hornyak M.S. Garett Sugimoto M.S. Kevin W.P. Miller Ph.D. 《Journal of forensic sciences》2015,60(4):857-868
Computer methods have been developed for mathematically interpreting mixed and low‐template DNA. The genotype modeling approach computationally separates out the contributors to a mixture, with uncertainty represented through probability. Comparison of inferred genotypes calculates a likelihood ratio (LR), which measures identification information. This study statistically examined the genotype modeling performance of Cybergenetics TrueAllele® computer system. High‐ and low‐template DNA mixtures of known randomized composition containing 2, 3, 4, and 5 contributors were tested. Sensitivity, specificity, and reproducibility were established through LR quantification in each of these eight groups. Covariance analysis found LR behavior to be relatively invariant to DNA amount or contributor number. Analysis of variance found that consistent solutions were produced, once a sufficient number of contributors were considered. This study demonstrates the reliability of TrueAllele interpretation on complex DNA mixtures of representative casework composition. The results can help predict an information outcome for a DNA mixture analysis. 相似文献
