To date, field experiments on campaign tactics have focused overwhelmingly on mobilization and voter turnout, with far more limited attention to persuasion and vote choice. In this paper, we analyze a field experiment with 56,000 Wisconsin voters designed to measure the persuasive effects of canvassing, phone calls, and mailings during the 2008 presidential election. Focusing on the canvassing treatment, we find that persuasive appeals had two unintended consequences. First, they reduced responsiveness to a follow-up survey among infrequent voters, a substantively meaningful behavioral response that has the potential to induce bias in estimates of persuasion effects as well. Second, the persuasive appeals possibly reduced candidate support and almost certainly did not increase it. This counterintuitive finding is reinforced by multiple statistical methods and suggests that contact by a political campaign may engender a backlash. 相似文献

AbstractDespite an overall decrease in residential mobility after the 2007 housing crisis, many households, particularly those that are low income, continue to move in pursuit of a better life. Traditional theories of residential mobility suggest that mobility will occur when housing and transportation costs are cumulatively greater than the cost of moving to a new location. At the same time, the influence of these factors is not likely to be uniform across geographic contexts or for moves up or down the metropolitan hierarchy. Our analysis examines how well affordability measures explain patterns of county-level residential mobility. Specifically, we contrast conventional measures of affordability focused on the ratio of income to housing expense with measures of location affordability that factor in both housing and transportation costs. We find that whereas households tend to move from lower to higher cost locations, transit affordability at the destination plays an important role in mobility decisions. 相似文献

Public management is a domain of research that is now roughly three decades old. Researchers in this area have made important advances in understanding about the performance of public organizations. But questions have been raised about the scope and methods of public management research (PMR). Does it neglect important questions about the development of major institutions of the modern state? Has it focused unduly on problems of the advanced democracies? Has it made itself irrelevant to public debates about the role and design of government, and the capacity of public institutions to deal with emerging challenges? This set of eight short essays were prepared for a roundtable held at the research conference of the PMR Association at the University of Aarhus in June 2016. Contributors were asked to consider the question: Is PMR neglecting the state? 相似文献

ABSTRACTThis contribution reflects upon the nexus between transitional justice and peacebuilding through a study of how transitional justice practices in post-Qadhafi Libya interacted with broader efforts to establish governance institutions in the aftermath of Libya’s 2011 armed conflict. It argues that dominant practices of transitional justice, promoted by external actors, prescribed narrow state-centric justice interventions that were ill-suited for a polity in which the state was highly contested. In fact, transitional justice proved divisive in Libya because attempts to project state-centric liberal justice practices were limited by their targeting of weak institutions that lacked local legitimacy and their inability to reconcile alternative normative frameworks that challenge the modern state. In addition, the weakness of Libya’s state institutions allowed thuwwar, or revolutionary armed groups, to dictate an exclusionary form of justice known as political isolation. Drawn from fieldwork conducted in Libya, this contribution provides lessons for both peacebuilding and transitional justice practice that call for a rethinking of teleological notions of transition and greater engagement with notions and concepts that fall outside dominant practices. 相似文献

To understand why some international institutions have stronger dispute settlement mechanisms (DSMs) than others, we investigate the dispute settlement provisions of nearly 600 preferential trade agreements (PTAs), which possess several desirable case-selection features and are evoked more than is realized. We broaden the study of dispute settlement design beyond “legalization” and instead reorient theorizing around a multi-faceted conceptualization of the strength of DSMs. We posit that strong DSMs are first and foremost a rational response to features of agreements that require stronger dispute settlement, such as depth and large memberships. Multivariate empirical tests using a new data set on PTA design confirm these expectations and reveal that depth – the amount of policy change specified in an agreement – is the most powerful and consistent predictor of DSM strength, providing empirical support to a long-posited but controversial conjecture. Yet power also plays a sizeable role, since agreements among asymmetric members are more likely to have strong DSMs due to their mutual appeal, as are those involving the United States. Important regional differences also emerge, as PTAs across the Americas are designed with strong dispute settlement, as are Asian PTAs, which contradicts the conventional wisdom about Asian values and legalization. Our findings demonstrate that rationalism explains much of international institutional design, yet it can be enhanced by also incorporating power-based and regional explanations. 相似文献

Sachil Kumar M.Sc. Wahid Ali Ph.D. Uma S. Singh M.D. Ashutosh Kumar M.D. Sandeep Bhattacharya M.D. Anoop K. Verma M.D. Raja Rupani M.D. 《Journal of forensic sciences》2016,61(Z1):S241-S245
Estimation of time of death is an indispensible requirement of every medico‐legal autopsy, but unfortunately, there is not a single method by which it could be determined accurately. This study focused on the temperature‐dependent postmortem degradation of cardiac troponin‐T and its association with postmortem interval (PMI) in human. The analysis involved extraction of the protein, separation by denaturing gel electrophoresis (SDS‐PAGE), and visualization by Western blot using cTnT‐specific monoclonal antibodies. The area of the bands within a lane was quantified by scanning and digitizing the image using Gel Doc (Universal Hood). The results indicate a characteristic banding pattern among human cadavers (n = 6) and a pseudo‐linear relationship between percentage of cTnT degradation and the log of the time since death (r > 0.95), which can be used to estimate the postmortem interval. The data presented demonstrate that this technique can provide an extended time range during which PMI can be more accurately estimated. 相似文献

Michael C. Taylor Ph.D. Terry L. Laber B.S. Paul E. Kish M.Sc. Glynn Owens Ph.D. Nikola K. P. Osborne Ph.D. 《Journal of forensic sciences》2016,61(4):922-927
This study was designed to produce the first baseline measure of reliability in bloodstain pattern classification. A panel of experienced bloodstain pattern analysts examined over 400 spatter patterns on three rigid non‐absorbent surfaces. The patterns varied in spatter type and extent. A case summary accompanied each pattern that either contained neutral information, information to suggest the correct pattern (i.e., was positively biasing), or information to suggest an incorrect pattern (i.e., was negatively biasing). Across the variables under examination, 13% of classifications were erroneous. Generally speaking, where the pattern was more difficult to recognize (e.g., limited staining extent or a patterned substrate), analysts became more conservative in their judgment, opting to be inconclusive. Incorrect classifications increased as a function of the negatively biasing contextual information. The implications of the findings for practice are discussed. 相似文献
