Scotland’s future within the European Union (EU) played a prominent role in the 2014 independence referendum. The story goes that latent supporters of independence voted to stay within the UK to maintain EU access. Defeated, Scottish leaders declared the referendum a once-in-a-life-time event only repeated if conditions substantially changed. With the UK now facing a chaotic exit from the EU, proponents of Scottish independence have suggested that a second referendum may occur after Brexit negotiations are completed. Faced with a consensus among Scottish party leaders in supporting EU membership, those hoping for a second independence referendum, we argue, looked to alternate sources of information that saw Brexit as an opportunity to create the conditions that would spur a second referendum. Using panel data from the British Election Study, we examine whether Scottish voters voted tactically to leave the EU. We argue that Scottish National Party voters were likely to interpret statements on the conditions for a second independence referendum as an implicit signal to vote “Leave.” The results have important implications for the role of referendums in representative democracy, strategic voting, and the importance of intra-party division on individual vote choices.  相似文献

A comparative analysis of Islamic extremism post-9/11 to 2015 and the effectiveness of the counterterrorism (CT) authorities to counter it in both Western Europe and the United States was conducted. Four measures of effectiveness revealed that 2010–2015 saw a gradual increase in jihadi attacks and in casualties emanating from these attacks, and more jihadists, foreign fighters, and material supporters. Additionally, 2013–2015 saw a 22 percent reduction both in Western Europe and the U.S. CT agencies' ability to counter Islamic extremism. We are losing the War on Terror and our citizens are less safe than they were six years ago. Further analysis revealed that singleton jihadists: (1) were much harder than group-based jihadists to uncover, (2) have been increasing since 2009, and (3) have generated over 70 percent of all jihadi violence. Finally, numerous similarities exist between Western Europe and the United States with respect to jihadism in their homelands and their respective CT effectiveness, indicating close cross-Atlantic CT collaboration since 9/11. This in-depth analysis provides essential threat/hazard information to security, law enforcement, intelligence, and policymaking personnel and the greater homeland security communities.  相似文献

Abstract

Politicians, diplomats and analysts commonly assume that commitment to multilateralism and liberal norms is part of the EU’s very DNA. Increasingly, however, the EU’s commitment to the liberal global order is more selective. We demonstrate the shift to a more contingent liberalism by examining the EU’s recent record in relation to four different challenges: international trade; US leadership; Russian actions in the eastern neighbourhood; and security in the Middle East. We speculate on what this may portend for the EU’s self-identity, European interests and the integrity of the prevailing global order.  相似文献

In Weimar Germany, the Catholic Church vehemently warned ordinary parishioners about the dangers of extremist parties. We establish that constituencies' religious composition is a key empirical predictor of Nazi vote shares—dwarfing the explanatory power of any other demographic or socioeconomic variable. Even after carefully accounting for observational differences, Catholics were far less likely to vote for the NSDAP than their Protestant counterparts. The evidence suggests that this disparity was, in large part, due to the sway of the Catholic Church and its dignitaries. At the same time, we show that attempts to immunize Catholics against the radical left failed to achieve the desired result. To explain the puzzling asymmetry in the Church's influence at the ballot box, we develop a simple theoretical framework of elite influence in electoral politics.  相似文献

No book is more exemplary in identifying the continuity of democratic statesmanship in the United States than Richard Hofstadter's second book. Its scope is long—from the Framers through the New Deal. The author's insights are brilliant, expressed with literary brio. No other book manages to convey the basic homogeneity of American politics with such persuasiveness, in blending that tradition with the defense of enterprise and property (and in sprinkling the portraits with such acerbic wit). The unifying thread nevertheless needs to be modified in the light of greater sensitivity to the ordeal of race, and in evaluating how the heritage of the New Deal has tempered the commitment to an unbridled capitalism.  相似文献

The Laboratory for Analytic Sciences (LAS) at North Carolina State University, funded by the National Security Agency, is a collaborative, long-term research enterprise focused on improving intelligence analysis using Big Data. In its work, LAS has recently begun dealing with the trade-off between the collection, storage, and use of large unclassified data-sets and analyst privacy. We discuss particular privacy challenges at LAS, analyze privacy principles in the life cycle of LAS unclassified data-sets, what intelligence analysts themselves think about these privacy concerns, and recommend possible best practices potentially applicable to LAS, as well as future Big Data laboratories and research centers that collaborate with intelligence communities.  相似文献

Structured analytic techniques (SATs) are intended to improve intelligence analysis by checking the two canonical sources of error: systematic biases and random noise. Although both goals are achievable, no one knows how close the current generation of SATs comes to achieving either of them. We identify two root problems: (1) SATs treat bipolar biases as unipolar. As a result, we lack metrics for gauging possible over-shooting—and have no way of knowing when SATs that focus on suppressing one bias (e.g., over-confidence) are triggering the opposing bias (e.g., under-confidence); (2) SATs tacitly assume that problem decomposition (e.g., breaking reasoning into rows and columns of matrices corresponding to hypotheses and evidence) is a sound means of reducing noise in assessments. But no one has ever actually tested whether decomposition is adding or subtracting noise from the analytic process—and there are good reasons for suspecting that decomposition will, on balance, degrade the reliability of analytic judgment. The central shortcoming is that SATs have not been subject to sustained scientific of the sort that could reveal when they are helping or harming the cause of delivering accurate assessments of the world to the policy community.  相似文献

Supreme Court confirmation hearings have been famously called a “vapid and hollow charade” by Elena Kagan. Indeed, perceptions of nominees’ refusal to answer questions about pending cases, prominent political issues, or give any hint of their ideological leanings have become a cornerstone of the modern confirmation process. We investigate the extent to which this reticence to speak of their ideological views, or candor, influences how individuals evaluate the nominee. To this end, we present the results of a survey experiment which examines how support for a hypothetical Supreme Court nominee is affected by information, especially when a nominee is presented to be very forthright or very reticent in answering ideological questions during the confirmation hearings. We find that while partisan compatibility with the president is the main determinant of support for a nominee, nominees who refuse to answer ideological questions can bolster support from respondents who would not support them on partisan grounds. We supplement these findings with observational state-level support data from real nominees over the last 40 years.  相似文献
