Research indicates that voters are not particularly effective at removing corrupt politicians from office, in part because voters make decisions on the basis of many competing factors. Party leaders are much more single-minded than voters and will choose to deselect implicated legislators if it means maintaining a positive party reputation and improving the odds of winning a legislative majority. We examine renominations to Italy’s legislature in two periods marked by corruption. We compare these renomination patterns with those from the prior legislature, when corruption lacked political salience. Our analysis shows that incumbent renominations are negatively associated with the number of press mentions that link the incumbent to corruption—but only when corruption is salient to the public. Our study highlights the importance of party leaders in forcing malfeasant legislators out of office—and reducing corruption—and redirects attention from voters to political elites as a critical channel in enforcing democratic accountability. 相似文献

Indigenous Australians continue to experience entrenched disadvantage. Despite billions being spent, ‘Closing the Gap’ indicators remain resistant to change. It has become increasingly apparent that progress has been hindered by persistent administration and implementation issues in Indigenous Affairs, especially with the funding modalities deployed. This study uses the remote Queensland Indigenous community of Aurukun as a case study to examine the effectiveness and evaluation problems arising from overlapping programmes delivered to Aurukun children and youth (5–18 years of age). It documents programmatic crowding occurring in Aurukun, which has the potential to place considerable demands on the intended participants, and results in hybridised effects that are not understood. Within this context, robust evaluation – even through the use of sophisticated methods – is near impossible. 相似文献

A Pretext for Regression? The Gendered Institutional Response to COVID-19 in the Country of Football
This article considers the gendered institutional response to COVID-19 in Brazilian football. It is argued that the asymmetries of power which shaped policy are rooted in the historical marginalisation of women's sports in the country along with socially constructed notions of hegemonic masculinity. The COVID-19 pandemic has served to accentuate deeply embedded social and economic inequalities and may serve as a pretext for eroding precarious gains made in recent times. 相似文献

Microbial communities have potential evidential utility for forensic applications. However, bioinformatic analysis of high-throughput sequencing data varies widely among laboratories. These differences can potentially affect microbial community composition and downstream analyses. To illustrate the importance of standardizing methodology, we compared analyses of postmortem microbiome samples using several bioinformatic pipelines, varying minimum library size or minimum number of sequences per sample, and sample size. Using the same input sequence data, we found that three open-source bioinformatic pipelines, MG-RAST, mothur, and QIIME2, had significant differences in relative abundance, alpha-diversity, and beta-diversity, despite the same input data. Increasing minimum library size and sample size increased the number of low-abundant and infrequent taxa detected. Our results show that bioinformatic pipeline and parameter choice affect results in important ways. Given the growing potential application of forensic microbiology to the criminal justice system, continued research on standardizing computational methodology will be important for downstream applications. 相似文献

This study describes the performance of handheld Raman devices for determining whether suspect pharmaceutical tablets declared to contain controlled substances were consistent with authentic (CWA) or not consistent with authentic (NCWA) tablets using a simple, rapid, field-friendly method capable of being used by nonexperts. Twenty-five authentic products and 84 known NCWA tablets were examined using three “parent” devices for a total of 327 analyses. On average, the parent devices yielded a true pass rate of 100%, a true fail rate of 98.4%, a false pass rate of 1.6%, and a false fail rate of 0%. The methods/libraries were then transferred to 13 identical “daughter” devices, which were used to examine 10 suspect finished dosage forms in duplicate (six known NCWA tablets and four authentic tablets) for a total of 260 measurements. On average, the daughter devices had a true pass rate of 100%, a true fail rate of 95.5%, a false pass rate of 4.5%, and a false fail rate of 0.0%. These data demonstrate that the parent–daughter electronic transfer method was successful, which permits the ability to develop methods in the laboratory that can be seamlessly pushed out to field devices. The methods can then be used to (i) prioritize samples for additional testing using other more time-consuming laboratory-based techniques needed to detect and quantify active ingredients and (ii) help support the interdiction of dangerous tablets at ports of entry, thereby preventing them from reaching the supply chain. 相似文献

China stands as a paradigmatic sign of deep angst for the United States in late stage capitalism, a menacing spectre of foreignness and otherness that organises Western popular anxieties at a time where nothing is fixed within international markets. Focusing on the so called “currency wars” debate that erupted in the early twenty-first century, when the PRC was accused of devaluating its currency, this article contends that PRC’s representation as a prime currency manipulator and cheater can be conceptualised through what I am calling monetary Orientalism or the ways imperialising thoughts circulate around monetary flows in relation to a rising Asiatic superpower. This framework serves as a prime lens for situating US nationalist sentiment and its sense of an exceptional global self against what it perceives as a global other. 相似文献

Both leadership and public value are increasingly seen as concepts highly relevant to public administration, not only because of complex societal challenges but also as ways to address pluralistic interests in society. This article explores in detail the varied conceptualizations of public value and of public leadership. Furthermore, we argue that political astuteness provides an important conceptual linkage between leadership and public value, enabling actors to read, understand and foster coalitions around diverse and sometimes competing interests. In this introduction to the symposium, we analyse the different conceptualizations of public value, of leadership, and also show how the six articles explicitly or implicitly draw on the linking concept of political astuteness. The article assesses how the six articles of the symposium contribute to each of these three concepts. 相似文献
