Arrow's axioms for social welfare functions are shown to be inconsistent when the set of alternatives is the nonnegative orthant in a multidimensional Euclidean space and preferences are assumed to be either the set of analytic classical economic preferences or the set of Euclidean spatial preferences. When either of these preference domains is combined with an agenda domain consisting of compact sets with nonempty interiors, strengthened versions of the Arrovian social choice correspondence axioms are shown to be consistent. To help establish the economic possibility theorem, an ordinal version of the Analytic Continuation Principle is developed. Received: 4 July 2000/Accepted: 2 April 2001  相似文献

Studies on immigrants' residential concentration have reported mixed findings. Some have argued that immigrants' residential concentration is a necessary step in the process of their social integration because there the newcomers find housing and employment opportunities as well as social support. As they learn the language and improve their socioeconomic status, they move to neighborhoods where they share space with the native population. Others have argued that the ethnic neighborhood delays the process of social integration in the new society because it nurtures informal ethnic social networks that provide incomplete information and retard the process of language acquisition. The study reported here investigated the effect of motivations, perceptions of attitudes of the host society, acculturation and socioeconomic factors on immigrants' residential concentration. It also sought to expand previous research by examining the relationship between immigrants'residential concentration and social relationships with nonimmigrants. Data for the study were collected in 1999 through a survey of immigrants from the FSU who had settled in one northern city in Israel after 1989. The results show a negative relationship of socioeconomic status and fluency in Hebrew with the percentage of immigrants residing in a given neighborhood. The higher the socioeconomic status and the more fluent the immigrant in Hebrew, the lower the percentage of immigrants in his or her neighborhood. Immigrants who expressed a proactive motivation for migration resided in neighborhoods with a low percentage of immigrants. Immigrants' residential concentration was not found to be related to the development of social relationships with the local population. The implications of the findings are discussed.  相似文献

Une perspective de la construction sociale sert de cadre a l'analyse des controverses sur la gestion des risques qui ont été provoquées à la suite d'un incendie majeur dans une usine de recyclage de matières plastiques à Hamilton, en Ontario. En mettant l'accent sur les processus de réclamation au c?ur de l'interaction entre les représen‐tants du gouvernement, les acteurs environnementaux, les experts techniques et les résidants, il a été révélé qu'un accent trop limité aux questions d'ordre technique avait mené a l'exclusion des préoccupations fondées sur la rationalité culturelle ayant ainsi entraine un cadre d'interaction très litigieux divisant profondément. Les conséquences des conclusions empiriques de la thése de la société des risques ainsi que de la théorie sur la communication des risques sont explorées. A social construction perspective is applied in the analysis of the risk management controversies that arose in response to a large toxic fire that occurred at a Hamilton, Ontario plastics recycling facility. By focussing on the claimsmaking processes involved in the interaction of government officials, environmental movement actors, technical experts, and residents, it was found that an overly narrow focus on technical matters led to the exclusion of lay concerns based on cultural rationality, thereby resulting in a very contentious and divisive setting for interaction. Implications of the empirical findings for the risk society thesis and risk communication theory are explored.  相似文献

Basic values, attitudes toward the homeless, and specific beliefs about a proposed facility were examined, along with the NIMBY (Not In My BackYard) phenomenon, to explore if, and to what degree, these factors affect community acceptance or rejection of a facility for the homeless. Previously designed Protestant ethic (PE) and Humanitarian-Egalitarian (HE) scales were used to measure two basic values (Katz & Hass, 1988). Scales to measure attitudes toward the homeless and beliefs about a planned facility were developed. As predicted, values, attitudes, and beliefs correlated with each other and were related to plan acceptance, so that HE, pro-homeless attitudes, and positive beliefs about the plan were positively related to acceptance, and PE, anti-homeless attitudes, and negative beliefs about the plan were positively related to rejection. Also as predicted, four proximity measures were all related to acceptance of the plan.  相似文献

Betrayal by a significant object is seen as primary in causing behavioral and emotional disturbances in incest victims, leading to a pervasive identification with the aggressor and disturbances in object relations development. Identification with the aggressor is understood not as a uniform defense mobilized against a specific affect but as a complex compromise formation which defends against anxiety, while also providing libidinal, aggressive and superego gratifications. Far from simply attempting to overcome the past, identifications thus preserve affects that have become pleasurable and self-defining. Two case studies of adolescent girls illustrate how treatment can help victims recognize and begin to forego the sadomasochistic pleasure derived from these identifications, a relinquishment necessary for true mastery.  相似文献

The extent of carcinogen regulation under existing U.S. environmental statutes is assessed by developing measures of the scope and stringency of regulation. While concern about cancer risk has played an important political role in obtaining support for pollution control programs, it has not provided the predominant rationale for most regulatory actions taken to date. Less than 20% of all standards established to limit concentrations of chemicals in various media address carcinogens. Restrictions on chemical use are more frequently based on concerns about noncancer human health or ecological effects. Of the chemicals in commercial use which have been identified as potential human carcinogens on the basis of rodent bioassays, only a small proportion are regulated. There is an inverse relationship between the scope of regulatory coverage and the stringency of regulatory requirements: the largest percentages of identified carcinogens are affected by the least stringent requirements, such as information disclosure. Standards based on de minimis cancer risk levels have been established for only 10% of identified carcinogens and are restricted to one medium: water. Complete bans on use have affected very few chemicals. The general role that carcinogenicity now plays in the regulatory process is not dramatically different from that of other adverse human health effects: if a substance is identified as a hazard, it may eventually be subject to economically achievable and technically feasible restrictions.  相似文献

This paper deals with parents' perspectives and experiences of bringing up children with a variety of impairments in Iceland, and how they impact the young disabled adults' approach to the status of adulthood. The paper is based on a qualitative study that explored perspectives and experiences of 36 young disabled adults (16-24 years old), their parents, friends and teachers. The purpose of this paper is to share themes related to patterns of parents' reactions and choices when coming to terms with parenting a disabled child, the support they found from their social network and professionals, and their sons or daughters' subsequent views of themselves and their prospects as young adults. The paper includes different perspectives on adulthood and the extent to which the young disabled people expect to reach that status or remain as 'eternal youth' enmeshed in segregated services. Findings show that the type and nature of early support for parents of disabled children is critical for the young adults' approaching adulthood in regular society or expecting to remain in the limbo of 'eternal youth' within segregated settings. Early 'betrayals' may, however, be revisited at each subsequent transition point. Furthermore, parents and their disabled children who struggled for social inclusion could obtain full active membership in society, even against social and physical barriers, and medically defined disability labels.  相似文献

In this paper, with the use of linear regressions to investigate how relationship dissolution affects sexual attitudes and behaviors, the authors address the stereotype that newly single people seek multiple sexual partners. Although the newly single people surveyed did obtain new sexual partners, the rate at which they acquired new partners did not support the stereotype. Specifically, men with custody of their children seemed oriented toward finding a steady partner. Additionally, men and women with low incomes reported relatively high rates of partner acquisition after relationship dissolution. The high rates reported by disadvantaged groups may be more directly related to familial instability accompanying poverty than to cultural characteristics associated with income or race. We argue that a life stage model with categorical stages in a rigid, anachronistic progression provides insufficient means to gain an understanding of newly single people.  相似文献
