Normative deliberative theory has contributed much to an understanding of ideal procedural standards, but there is considerable uncertainty regarding the appropriate nature of desired deliberative outcomes. In this paper we identify two inter‐related concepts of meta‐consensus and inter‐subjective rationality as outcomes that an authentic deliberative process ought to produce. Importantly, these deliberative ends are consistent with ideal deliberative procedure. They are also empirically tractable, where preference transformation can be described in terms of underlying values, and judgments. Methods for assessing deliberative ends are provided and demonstrated using a case study.  相似文献

Interdisciplinary deliberative research has grown tremendously over the last decade. Theorists are attending more carefully to the findings of empirical research. And empiricists are framing their research in ways that are tailored to track normative‐theoretical concerns. The recent surge in empirical work on deliberation, however, has led to a huge proliferation of research designs, general measurement strategies, operational criteria, and even definitions of the phenomenon. The diversity in these approaches has become sufficiently great that it seems worthwhile to step back and take stock lest the expanding deliberative research community dissipate its energies in an ironic lack of effective communication across theoretical and methodological approaches. I survey the main sources of theoretical diversity among normative theories of deliberation, along with the diversity of basic strategies for measuring deliberation that follow from them.  相似文献

Appraisals about the implications of stressful events that are evaluated as involving a threat to self (negative self-evaluation, negative evaluation from others, rejection by others) have been shown to place youth at risk for the development of mental health problems. This longitudinal study tested a protective-stabilizing interactive model, in which high maternal acceptance was predicted to mitigate the prospective relation between threat to self appraisals and change in adolescents’ mental health problems six months later. Participants were 89 adolescents from divorced families ages 10–12 and residential mothers. Adolescents reported on threat to self appraisals from the most stressful event experienced in the past month. Mothers and youth reported on maternal acceptance and mental health problems. Multiple regression analyses provided support for the protective effects of maternal acceptance on adolescents’ mental health problems. Intervention implications are discussed. Ana Brown is a pre-doctoral fellow in prevention research (NIMH 2 T32 MH18387–19) and doctoral student in the Department of Psychology at Arizona State University, Tempe, AZ. Research interests include the study of children’s appraisals and responses to stressful events in the prevention of mental health problems. Sharlene Wolchik is a clinical psychologist and professor in the Department of Psychology at Arizona State University, Tempe, AZ. Her research focuses on identifying risk and protective factors for children whose parents have divorced. She also has designed and evaluated the efficacy of preventive interventions for children from divorced families and children who have experienced parental bereavement. Jenn-Yun Tein is a research associate professor and Co-Director of the Research Methodology Core of the Prevention Research Center at Arizona State University, Tempe, AZ. Her research interests include analyses of mediation and moderation of preventive interventions as well as applications of methodology and statistics in prevention research. Irwin Sandler is a Regents’ Professor in the Department of Psychology and Director of the Prevention Research Center at Arizona State University, Tempe, AZ. His research interests focus on understanding resilience for children exposed to stress and on the development, evaluation and dissemination of programs to promote resilience and prevent mental health problems for children in stress.  相似文献

This paper empirically analyzes whether government size is conducive or detrimental to life satisfaction in a cross-section of 74 countries. We thus provide a test of the longstanding dispute between standard neoclassical economic theory and public choice theory. According to the neoclassical view, governments play unambiguously positive roles for individuals' quality of life, while the theory of public choice has been developed to understand why governments often choose excessive involvement in – and regulation of – the economy, thereby harming their citizens' quality of life. Our results show that life satisfaction decreases with higher government consumption. For low, middle income, and male people, this result is stronger when the government is leftwing, while government consumption appears to be less harmful for women when the government is perceived to be effective. Government capital formation and social spending have no significant impact on life satisfaction.  相似文献

Where does history education fit into transitional justice andhow can it contribute to the goals of transitional justice?The contemporary understanding of transitional justice has broadenedto encompass more than just prosecutions, reparations, preventingimpunity, and building rule of law. Transitional justice goalsnow extend to truth telling, restoring the dignity and preservingthe memory of victims, building peace, creating respect forhuman rights and democracy, and to reconciliation. Tools forachieving these goals now include truth commissions and commemorations.But this list has not until now included how the historicalnarrative of the group(s) involved in conflict must change asa part of transition; and education, while often invoked whenthe topic of ‘never again’ is raised, has been largelyabsent from the transitional justice discourse. Neither thelarger education system nor the teaching of history –both what is taught and how – has been considered by theinstitutions transitional justice has aimed to reform. Thisarticle considers why history education matters, what conditionscomplicate its reform and what recommendations can begin tobe offered with regard to the relationship between history educationand transitional justice.  相似文献

Use of Force     
Waddington  P. A. J. 《Policing》2007,1(3):249-251
This issue of Policing: A Journal of Policy and Practice, isdevoted principally to the use of force, a topic that has dominatedacademic debate and preoccupied practitioners. For academics,the question is: what distinguishes police officers and theorganisations in which they operate from others, particularlythose growing legions of private security operatives, un-swornpolice auxiliaries, and sundry officials with law enforcementpowers? The orthodox answer is that the police enjoy a ‘monopolyof legitimate force’ over their fellow citizens (a viewthat has its origins in the pioneering work of Bittner, 1970).That orthodoxy has increasingly been criticised in the faceof the obvious fact that bouncers, store detectives, securityguards of all kinds, and many others also exercise ‘legitimateforce’ in ejecting drunken customers from pubs and clubs,apprehending shoplifters, and defending  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

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
