 This paper attempts to provide a unified account of the rationalization of possibly non-binary choice-functions by “Extended Preference Relations” (relations between sets and elements). The analysis focuses on transitive EPRs for which three choice-functional characterizations are given, two of them based on novel axioms. Transitive EPRs are shown to be rationalizable by sets of orderings that are “closed under compromise”; this novel requirement is argued to be the key to establish a canonical relationship between sets of orderings and choice-functions. The traditional assumption of “binariness” on preference relations or choice functions is shown to be analytically unhelpful and normatively unfounded; non-binariness may arise from “unresolvedness of preference”, a previously unrecognized aspect of preference incompleteness.

This paper introduces the “Extended Pareto” axiom on Social Welfare Functions and gives a characterization of the axiom when it is assumed that the Social Welfare Functions that satisfy it in a framework of preferences over lotteries also satisfy the restrictions (on the domain and range of preferences) implied by the von-Neumann Morgenstern axioms. With the addition of 2 other axioms: “Anonymity” and a weak version of Arrow's Independence of Irrelevant Alternatives axiom: “Weak IIA” it is shown that there is a unique Social Welfare Function called “Relative Utilitarianism” that consists of normalising individual utilities between 0 and 1 and adding them.

Passed in 1966, The Freedom of Information Act (FOIA) has provided nearly thirty years of access to government information virtually unmatched throughout the world. Used heavily by the media, it has been virtually ignored by sociologists. Nonetheless, it promises access to a potential wealth of data for sociological research. Following a brief discussion of the history of federal information policy and the FOIA, some suggestions for possible research applications are made. Implications for further research are presented, including the emergence of two new classes, information “haves” and information “have-nots,” indicating a new dimension for stratification research in contemporary society.  相似文献

Previous research demonstrated that viewers’ judgments of an interviewee are influenced by the nonverbal behavior of the interviewer. In studies of this media bias effect, judges view a short political interview with a friendly or a hostile interviewer, and then rate their impressions of the interviewee, whose behavior remains identical in all conditions. The present research utilizes the same design and materials to explore potential cognitive remedies, to investigate the effect of attitude similarity on media bias, and to meta-analyze seven replications of the media bias effect. In Study 1, a cognitive remedy in the form of an instruction to ignore the interviewer neutralized and even reversed the media bias effect. In Study 2, insertion of a brief segment depicting a “beaming” and relaxed interviewee also reversed the media bias effect. Study 3 demonstrated that negative ratings of the interviewee due to interviewer’s hostility were intensified when respondents considered the interviewee as “one of them” politically, and disappeared when he was perceived as “one of us”. Study 4 demonstrated the consistency of the media bias effect by meta-analyzing seven replications in different countries. Implications for nonverbal research and for media research concerning the consistency of the media bias effect and its amenability to remedy are discussed.  相似文献

A number of researchers have recently challenged the long-held notion among criminologists that rape, along with most other violent crimes, is an intraracial crime. Based on analysis of survey data they concluded that black rapists “prefer” or “seek out” white victims and that the likelihood of a black offender selecting a white victim has been increasing during recent years. Data presented here (1977–88 National Crime Surveys) refute the notion that black rapists “prefer” white victims. Moreover these same data fail to support the contention that rapes involving black offenders and white victims have been increasing. According to National Crime Survey estimates, the proportion of black offenders that victimize whites has been declining. An earlier version of this paper was presented at the annual meetings of the American Society of Criminology, November 1991.  相似文献

In the last decade, under the pressing processes of immigration and globalisation, many Western constitutional democracies have moved from a number of religions sharing a common culture to today’s age of diversity. What current democracies are facing is the lack of overlapping consensus over basic constitutional “values”. The nature, scope and force of such values are likely to be affected by competing and, sometimes, contested fundamental reasons and worldviews. From here stems the dilemma between “unity” and “diversity”. This essay starts with a broad consideration on the principle of religious freedom, strictly related to the separation as well as collaboration between secular States and Churches; then the author analyses two case-studies (France and Canada), pointing out some specific legal approaches. In particular he focuses the analyses over the French “droit commun” and the Canadian arbitral tribunals that, especially in family law, allow disputes to be arbitrated using religious jurisdictions.  相似文献

Among others, the term “problem” plays a major role in the various attempts to characterize interdisciplinarity or transdisciplinarity, as used synonymously in this paper. Interdisciplinarity (ID) is regarded as “problem solving among science, technology and society” and as “problem orientation beyond disciplinary constraints” (cf. Frodeman et al.: The Oxford Handbook of Interdisciplinarity. Oxford University Press, Oxford, 2010). The point of departure of this paper is that the discourse and practice of ID have problems with the “problem”. The objective here is to shed some light on the vague notion of “problem” in order to advocate a specific type of interdisciplinarity: problem-oriented interdisciplinarity. The outline is as follows: Taking an ex negativo approach, I will show what problem-oriented ID does not mean. Using references to well-established distinctions in philosophy of science, I will show three other types of ID that should not be placed under the umbrella term “problem-oriented ID”: object-oriented ID (“ontology”), theory-oriented ID (epistemology), and method-oriented ID (methodology). Different philosophical thought traditions can be related to these distinguishable meanings. I will then clarify the notion of “problem” by looking at three systematic elements: an undesired (initial) state, a desired (goal) state, and the barriers in getting from the one to the other. These three elements include three related kinds of knowledge: systems, target, and transformation knowledge. This paper elaborates further methodological and epistemological elements of problem-oriented ID. It concludes by stressing that problem-oriented ID is the most needed as well as the most challenging type of ID.  相似文献

Conclusion Mills wrote to his Oxford publisher in 1955. “One book grows out of another; the trouble is not only is there no end to it, but after the second is pressing upon you before you can finish the first, for planning is more fun than working.” 78 Indeed, this mode of working was common to all of Mills’ projects. He worked fast and furiously and always juggled a number of different ideas in various stages of formation. This certainly was the case with The Cultural Apparatus. In a 1955 letter to his publisher Mills enthusiastically said of the book “I'm into it.” He predicted, optimistically, that unlike his other books, this book would be easy, a natural for him that “writing it will not involve the anguish that White Collar and Elites have provided.” By 1959, however, Mills had to admit that this optimism was premature. In “The Personal Note to the Reader” he confessed that “I've never had so much trouble writing a book as I have with this one, and I’ve never taken so much pain with the writing of it as I’ve taken to heart the criticism of being repetitious, verbose and prone to jargon.” 79 Mills never completed the project. By the late 1950's he became preoccupied with the political issues of “war and peace” and American foreign policy in Cuba, the latter in particular. His health was poor as a result of a heart attack he suffered in December of 1959 on the eve of a televised debate with an American advisor in Latin America, A.A. Berle. He became embroiled in what he understood as necessary public work from within the media and he remained adamant about the personal significance of The Cultural Apparatus in 1959.  相似文献

Richard Freeman and James Medoff have asserted that labor unions have two “faces,” a “good” face and a “bad” face. This contribution critically examines their arguments to expose serious flaws in their conceptual analysis.  相似文献

Factor scores on a gambling expectancy questionnaire (GEQ) were used to subtype 132 university students who gamble regularly (37.9% male; M age = 22.6 years, SD = 6.04) as: Reward Expectancy Gamblers (Reward EGs)—have strong expectations that gambling augments positive mood, Relief Expectancy Gamblers (Relief EGs)—have strong expectations that gambling relieves negative affect, and Non-Expectancy Gamblers (Non-EGs)—have neither strong expectation. Gambling on a high-low card game was compared across subtypes following priming for either “relief” or “reward” affect-regulation expectancies with the Scrambled Sentence Test (SST). The hypothesized Prime type × GEQ subtype interaction was not significant. When a more stringent set of criteria for GEQ subtyping was imposed, the “purified” sub-sample (n = 54) resulted in the hypothesized statistically significant Prime type × GEQ subtype interaction. Relief EGs gambled more after being primed with the construct “relief of negative emotions” compared to after being primed with the construct “augmentation of positive emotion.” Planned orthogonal contrasts showed a significant linear increase in number of bets made across GEQ subtypes when prime type corresponded to GEQ subtype. The results suggest a need for components in gambling treatment programs that address clients’ expectancies that gambling can provide a specific desirable emotional outcome.  相似文献

Despite the many angles from which the biological phenomenon now known as “the menstrual cycle” has been addressed, no work explicitly focuses on how social groups actually draw lines around and mentally partition these complex biological processes into discrete temporal units. This paper examines not the meaning of “the menstrual cycle,” per se, but hegemonic Western culture's intersubjective notions of how to carve up this inherently unstructured phenomenon in the first place. Although sociologists of cognition have still to consider this sociomental structuring of “the menstrual cycle” as a case of mental cartography, and sociologists of time have still to consider “menstrual time” as a case of sociotemporality, I conclude that the mental mapping out of what constitutes the elements of this rhythm is a highly social act with serious implications for women's lives.  相似文献

This article focuses on the Urban Area Security Initiative (UASI) controversy as a case study in the politics of risk assessment. It examines struggles among diverse actors–think tank experts, journalists, politicians, and government officials–engaged in the contentious process of establishing a legitimate definition of risk. In the field of homeland security, the means of conducting rational risk assessment have not yet been settled, and entrepreneurial officials from urban and regional governments use different techniques to identify local risks and vulnerabilities. In this contentious process, federal bureaucrats are responsible for determining how to allocate resources fairly and rationally to different cities and metropolitan regions, given that local officials have clear incentives to request funds and little cause to refrain. Although “rationality” is supposed to replace “politics” in making bureaucratic decisions over the allocation of resources, what we find instead is a political struggle over how to define, measure, and manage risk. For political actors, victory in debates over urban security comes from codifying one’s interests within the technical practice of risk assessment.  相似文献

Consistent judgement aggregation: the truth-functional case   总被引:1,自引:1,他引:0  
Generalizing the celebrated “discursive dilemma”, we analyze judgement aggregation problems in which a group of agents independently votes on a set of complex propositions (the “conclusions”) and on a set of “premises” by which the conclusions are truth-functionally determined. We show that for conclusion- and premise-based aggregation rules to be mutually consistent, the aggregation must always be “oligarchic”, that is: unanimous within a subset of agents, and typically even be dictatorial. We characterize exactly when consistent non-dictatorial (or anonymous) aggregation rules exist, allowing for arbitrary conclusions and arbitrary interdependencies among premises.  相似文献

Juvenile delinquency and high risk behaviors have been linked to disturbances in attachment. The present study examined parent and peer attachment in 67 African American males and 97 Latinos (ages 12–17, M = 14.7 ± 1.3) attending an alternative school. The Inventory of Parent and Peer Attachment was used to identify 3 attachment style groups: “Isolated,” “Disconnected,” and “Connected.” Controlling for age, attachment group membership predicted differences in delinquent behaviors, as did ethnicity. Further, on the Youth Self-Report of the Child Behavior Checklist, attachment group membership predicted differences in both the Internalizing and Externalizing Scales. Implications for interventions with each identified attachment group are discussed.  相似文献

Much recent literature plumbs the question of the origins and trajectories of “place,” or the cultural development of space-specific repertoires of action and meaning. This article examines divergence in two “places” that were once quite similar but are now quite far apart, culturally and politically speaking. Vermont, once considered the “most Republican” state in the United States, is now generally considered one of its most politically and culturally liberal. New Hampshire, by contrast, has remained politically and socially quite conservative. Contrasting legacies of tourist promotion, political mobilization, and public policy help explain the divergence between states. We hypothesize that emerging stereotypes about a “place” serve to draw sympathetic residents and visitors to that place, thus reinforcing the salience of those stereotypes and contributing to their reality over time. We term this latter process idio-cultural migration and argue its centrality to ongoing debates about the accomplishment of place. We also elaborate on several means by which such place “reputations” are created, transmitted, and maintained.  相似文献

This article focuses on Malawian sex workers’ understandings of exchange and intimacy, showing how multiple historically emergent categories and specific work pragmatics produce specific patterns of relational meanings. As we show, sex workers make sense of their relationships with clients through two categories. The first is sex work; the second is the chibwenzi, an intimate premarital relational category that emerged from pre-colonial transformations in courtship practices. These categories, in turn, are also shaped differently in different work settings. We use narratives from in-depth interviews with 45 sex workers and bar managers in southern Malawi to describe how the everyday pragmatics of two forms of sex work—performed by “bargirls” and “freelancers”—foster distinct understandings of relationships between them and men they have sex with. Bargirls, who work and live in bars, blurred the boundaries between “regulars” and chibwenzi; freelancers, who are not tethered to a specific work environment, often subverted the meanings of the chibwenzi, presenting these relationships as both intimate and emotionally distant. Through this comparison, we thus refine an approach to the study of the intimacy-exchange nexus, and use it to capture the complexities of gender relations in post-colonial Malawi.  相似文献

The “finesse point” introduced here extends the notion of a core; it is a position that minimizes what a candidate needs to do to counter moves that are made by an opponent. The definition, which is motivated by the “chaos theorem” as well as by the dynamics of positive and negative political campaigning, is also used to define a “malicious point,” which is an optimal location from which a candidate can engage in “negative campaigning.”  相似文献
