Does partisan conflict damage citizens’ perceptions of Congress? If so, why has polarization increased in Congress since the 1970s? To address these questions, we unpack the “electoral connection” by exploring the mass public's attitudes toward partisan conflict via two survey experiments in which we manipulated characteristics of members and Congress. We find that party conflict reduces confidence in Congress among citizens across the partisan spectrum. However, there exists heterogeneity by strength of party identification with respect to evaluations of members. Independents and weak partisans are more supportive of members who espouse a bipartisan image, whereas strong partisans are less supportive. People with strong attachments to a political party disavow conflict in the aggregate but approve of individual members behaving in a partisan manner. This pattern helps us understand why members in safely partisan districts engage in partisan conflict even though partisanship damages the collective reputation of the institution. 相似文献

C.E.R.A. (Continuous Erythropoietin Receptor Activator) is a new third-generation erythropoiesis-stimulating agent that has recently been linked with abuse in endurance sports. The anti-doping community rapidly reacted by releasing a high-throughput screening ELISA allowing the detection of C.E.R.A. doping in athletes' blood. In order to return adverse analytical findings, anti-doping laboratories, however, need, as far as possible, to confirm the presence of the drug in athletes' samples through orthogonal methods. This article focuses on the comparison of 2 proposed confirmation assays based on gel electrophoresis that were coupled with a new sample immunopurification method. IEF, the classical method used to target erythropoietin (EPO) and its recombinant analogues in athletes' samples, and SARKOSYL-PAGE were applied to the plasma samples of subjects having received a single injection of C.E.R.A. It was demonstrated that SARKOSYL-PAGE was at least 6 times more sensitive than IEF, with comparable specificity. A longer detection window coupled with easier interpretation criteria led us to recommend the use of SARKOSYL-PAGE to confirm C.E.R.A. presence in athletes' blood. 相似文献

We argue that an ‘electoral democracy’ is not sufficient to reduce corruption. Our contention is that the institutions associated with mature democracy are crucial to successfully deterring corrupt behaviour. At the core of our argument is the idea that with well-functioning institutions, the probability of detection and punishment is sufficiently high to deter most decision makers from choosing to act corruptly. The empirical evidence we present supports this idea. The nonlinearity of democracy variables is tested to confirm that an advanced stage of democracy is crucial for combating corruption. 相似文献
