Detective stories take place mainly in two settings, constantly changing, many faceted big cities filled with strangers, and stable, fairly homogeneous, innocent small towns whose members know one another. The differences in each clarify the qualities of the other. In solving the mystery of the small town, the detective provides moral instruction and restores the town’s innocence. In solving the mystery in the big city the detective reveals the city as part of the mystery and provides the reader with temporary orientation to the city. Mysteries have grown with the growth of the cities and now appear in every country of the world. Harold J. Bershady is an emeritus Professor of Sociology at the University of Pennsylvania. His most recent book, edited with Renée Fox and Victor Lidz, is After Parson: A Theory of Action for the 21st Century, published by Russell Sage Press, 2005.  相似文献

Political science has paid a great deal of attention to sources of intergroup conflict, but the discipline has focused less on forces that bring people together and lead them to transcend group boundaries. This study presents evidence that attachment to a shared superordinate identity can improve intergroup relations by reducing the social distance between people of different racial groups. Using a survey experiment, this research shows that making a superordinate identity salient increased support for a tax increase. The effects of the identity salience treatment are compared to a policy particularism treatment in terms of effect size and their interaction with each other. The size and direction of the identity salience effect is affected by the degree of respondents' acceptance of the proffered identity. Implications for social identity theory, racial policy attitudes, and American national identity are discussed.  相似文献

Almost all legislators are subordinate to party leadership within their assemblies. Institutional factors shape whether, and to what degree, legislators are also subject to pressure from other principals whose demands may conflict with those of party leaders. This article presents a set of hypotheses on the nature of competing pressures driven by formal political institutions and tests the hypotheses against a new dataset of legislative votes from across 19 different countries. Voting unity is lower where legislators are elected under rules that provide for intraparty competition than where party lists are closed, marginally lower in federal than unitary systems, and the effects on party unity of being in government differ in parliamentary versus presidential systems. In the former, governing parties are more unified than the opposition, win more, and suffer fewer losses due to disunity. In systems with elected presidents, governing parties experience no such boosts in floor unity, and their legislative losses are more apt to result from cross-voting.  相似文献

Campaigns rely upon both paid and volunteer phone calls to mobilize voters. Past field experiments show calls from volunteers to increase turnout and paid calls to be wholly ineffective. This article argues that the quality of phone calls rather than the presence or absence of a payroll explains this regularity. Three aspects of quality are considered: monitoring pace and interactivity, timing, and message. A fully randomized field experiment with over 100,000 subjects comparing professional and volunteer phone banks simultaneously was conducted during the 2002 congressional elections to test this hypothesis. The experiment discovers precisely the opposite relationship of prior research: effective professional phone banks and inefficient volunteer phone calls. The experiment also finds substantial temporal decay. The specific messages appear less important than tone or timing. The implications for the role of campaign consultants, replacing social capital, voter psychology, and the capacities of civic organizations are discussed.  相似文献

An Experimental Template for Case Study Research   总被引:1,自引:0,他引:1  
Methods are usually classified as either "experimental" or "observational," a dichotomy that has governed social science research for centuries. By implication, this dichotomization precludes a consideration of experimental strategies in case study work. Yet, we argue that one gains purchase on the tasks of research design by integrating the criteria traditionally applied to experimental work to all research in the social sciences—including case study work, the focus of this article. Experimental research designs aim to achieve variation through time and across space while maintaining ceteris paribus assumptions, thus maximizing leverage into the fundamental problem of causal inference. We propose to capture these multiple criteria in a four-fold typology: (1) A Dynamic comparison mirrors laboratory experimentation through the use of both temporal and spatial variation; (2) A Longitudinal comparison employs temporal variation; (3) A Spatial comparison exploits variation through space; and (4) A Counterfactual comparison relies on imagined comparison. All comparison case study research designs can be slotted into one of these four categories. Moreover, the typology illustrates in a concise fashion the ways in which case study research designs attempt to mimic the virtues of experimental design and the degree to which they succeed. The classic experiment, with manipulated treatment and randomized control, thus provides a useful template for discussion about methodological issues in experimental and observational contexts.  相似文献

We investigate how aspects of "civil service" systems of personnel management interact with bureaucratic discretion to create expert bureaucracies populated by policy-motivated agents. We construct a dynamic model in which bureaucrats may invest in (relationship-specific) policy expertise and may or may not be interested in policy choices per se. The legislature makes sequentially rational grants of discretion, which serve as incentives for expertise investment and continued service only for policy-motivated bureaucrats. Bureaucratic policy preferences and the legislature's agency problem vis-à-vis bureaucracies develop endogenously in the model. Bureaucratic expertise can be supported in equilibrium only at a cost of its politicization; "neutral competence" is inconsistent with strategic incentives of bureaucrats. We identify several conditions that support the development of an expert bureaucracy in equilibrium, including security of job tenure and control over policy issues for policy-motivated bureaucrats.  相似文献

Some scholars argue that the author of the majority opinion exercises the most influence over the Court's opinion-writing process and so can determine what becomes Court policy, at least within the limits of what some Court majority finds acceptable. Other students of the Court have suggested that the Court's median justice effectively dictates the content of the majority opinion: whatever policy the median justice most wants, she can get. We test these competing models with data on Supreme Court decision making during the Burger Court (1969–86). While we find substantial evidence for both models, the agenda control model gains greater support. This suggests that opinions on the Court on each case are driven, in general, by the interaction of three key variables: the policy preferences of the majority opinion author, the policy preferences of the median justice, and the location of the legal status quo .  相似文献

Public agencies use surveys to solicit feedback from citizens and targeted customer groups, but many experts question whether the results of these surveys are valuable. This paper explores how a recent innovation in citizen surveys—asking public administrators to predict how citizens will respond to survey questions—may be used to increase that value and, at the same time, provide additional data of interest on its own account. The innovation is explored through two surveys: (1) a public opinion poll of Georgia residents conducted by the authors for the Georgia Department of Transportation in January 2004, and (2) a brief survey of that agency's administrators asking for their predictions of public opinion. The prediction process appeared to increase the agency's interest in the resident survey. The findings document the frequent superiority of groups—what Surowiecki terms "the wisdom of crowds"—over individuals in predicting public opinion.  相似文献

A key to the success of public organizations is their ability to identify and build capacity, particularly their distinctive competencies, in order to produce the greatest value for key stakeholders. This article grounds this proposition in the resource-based view of organizations and presents a method for identifying and making use of distinctive competencies in the form of a "livelihood scheme"—a business model appropriate for the public sector—that links distinctive competencies to organizational aspirations and goals. The case of a major public sector training and consultancy unit that is part of the United Kingdom's National Health Service is used as illustration. A number of conclusions are offered in the form of a set of propositions tied to the resource-based view and related research issues. The results contribute to both public strategic management theory and practice.  相似文献
