The purpose of this study is to explore experiences of social devaluation among people living in poverty. Twenty-five long-standing recipients of social security payments living in a city in Norway were interviewed. Most felt that people in their environment held low opinions of them regarding issues related to personality and moral integrity. Several factors play a role in the formation of such beliefs or assumptions: (a) impressions of prevailing views of the social category "the poor" and observations concerning devaluation of that category; (b) knowledge others are assumed to possess of the respondents' financial predicament; (c) perception of own social situation; (d) undesired behavior that signals low social status and low esteem; (e) actions by others that signal devaluation. Social devaluation is also experienced at the affective level: the sense of shame and guilt is widespread.  相似文献

A transformative decision rule alters the representation of a decision problem, either by changing the set of alternative acts or the set of states of the world taken into consideration, or by modifying the probability or value assignments. A set of transformative decision rules is order-independent in case the order in which the rules are applied is irrelevant. The main result of this paper is an axiomatic characterization of order-independent transformative decision rules, based on a single axiom. It is shown that the proposed axiomatization resolves a problem observed by Teddy Seidenfeld in a previous axiomatization by Peterson.  相似文献

Selective Revision   总被引:1,自引:0,他引:1  
We introduce a constructive model of selective belief revision in which it is possible to accept only a part of the input information. A selective revision operator ο is defined by the equality K ο α = K * f(α), where * is an AGM revision operator and f a function, typically with the property ⊢ α → f(α). Axiomatic characterizations are provided for three variants of selective revision. This revised version was published online in June 2006 with corrections to the Cover Date.  相似文献

We prove that four theses commonly associated with coherentism are incompatible with the representation of a belief state as a logically closed set of sentences. The result is applied to the conventional coherence interpretation of the AGM theory of belief revision, which appears not to be tenable. Our argument also counts against the coherentistic acceptability of a certain form of propositional holism. We argue that the problems arise as an effect of ignoring the distinction between derived and non-derived beliefs, and we suggest that the kind of coherence relevant to epistemic justification is the coherence of non-derived beliefs. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

In 30-min free-operant tests, the dopamine receptor blockers pimozide (.125, .25, and .50 mg/kg) and (+)-butaclamol (.1, .2, and .4 mg/kg) attenuated lever pressing for lateral hypothalamic brain stimulation. When discrete self-stimulation trials were offered in a straight alleyway, pimozide increased start box latencies, slowed running speeds, and reduced lever-pressing rates. However, performance early in both lever-pressing and runway sessions was normal; performance deteriorated as testing progressed, following patterns that paralleled those seen when animals were tested with reductions in the amplitude of stimulating current. Spontaneous recovery was obtained in both situations; experimenter-imposed 10-min time-outs caused renewed lever pressing and running. In contrast, alpha-noradrenergic receptor blockade by phenoxybenzamine (5, 10, and 20 mg/kg) failed to produce extinction-like response patterns. These data support the view that central dopaminergic systems are important components of the neural mechanisms mediating reward.  相似文献

A field experiment using the "Lost Letter Technique" tested the hypothesis that altruism would be higher in small towns than in cities, unless the person needing help was a social deviant. The hypothesis was derived from Milgram's (1970) overload theory, in which city dwellers are expected to become generally indifferent to, and make fewer differentiations between, unimportant others. A total of 216 letters to one of three addressees (control, somewhat deviant, highly deviant) were "lost", one-half in Tulsa, Oklahoma (population: 347,600) and one-half among 51 small, Oklahoma towns (× population: 2,002). Return rates supported the hypothesis. The data also suggest that a greater intolerance in small towns for social deviance might systematically overwhelm their generally higher levels of social responsibility. Implications are drawn regarding the danger of overgeneralizing negative attributions to urban centers.  相似文献

The AGM (Alchourrón-GÄrdenfors-Makinson) model of belief change is extended to cover changes on sets of beliefs that arenot closed under logical consequence (belief bases). Three major types of change operations, namely contraction, internal revision, and external revision are axiomatically characterized, and their interrelations are studied. In external revision, the Levi identity is reversed in the sense that onefirst adds the new belief to the belief base, and afterwards contracts its negation. It is argued that external revision represents an intuitively plausible way of revising one's beliefs. Since it typically involves the temporary acceptance of an inconsistent set of beliefs, it can only be used in belief representations that distinguish between different inconsistent sets of belief.  相似文献

Assessing the social components of retirement anxiety   总被引:1,自引:0,他引:1  
In 4 studies involving 308 men and 384 women aged 25-76, a reliable instrument, the Social Components of Retirement Anxiety Scale (SCRAS), was developed to assess retirement anxiety. The 23-item SCRAS measures 4 factors:Social Integration and Identity, Social Adjustment/Hardiness, Anticipated Social Exclusion, and Lost Friendships. The scale strongly predicts fear of retirement and negative attitudes toward retirement. However, it seems not to be measuring simply a generalized emotional state, exhibiting only minimal correlations with more general measures of anxiety and depression. Elevated scores were observed particularly in persons for whom major social transitions are quite difficult--for example, those who were shy, lonely, had fewer instrumental or communal traits, or expected to have little personal control over their lives after retirement.  相似文献

The purpose of the present study was to evaluate the efficiency of temperature variations as a measure against drivers' drowsiness. A system for regulation of the air temperature in the cab was installed in two trucks. Irregular temperature reductions of about 8 degrees C were introduced. The periods between the temperature reductions varied among 5, 6, 7, and 8 min. The periods for the temperature reductions varied between 2, 4, 6, and 8 min. The system was tested with 6 drivers on 54 trips. The system was applied for periods varying between 30 to 300 min. Changes in wakefulness were analysed using subjective ratings by the lorry drivers. The application of the system significantly improved subjectively rated wakefulness. The wakefulness was rated with a questionnaire completed after 10 min. use of a cooling system and at the end of its use. Analysis showed individual differences in the usefulness of the system: 3 of the 6 truck drivers reported positive reactions to the use of the temperature cooling system.  相似文献

The SF-36 Health Survey and the WHO Quality of Life Index—BREF (WHOQOL-BREF) were used to study quality of life among women who had experienced intimate partner violence (IPV). The aim was to determine how these instruments correlated with each other and with physical and psychological IPV, in order to find the best instrument to use. IPV was measured using the Severity of Violence against Women Scale (SVAWS) and the Psychological Maltreatment of Women Index (PMWI). A self-administrated questionnaire was given to women able to understand Norwegian who were staying at a women’s shelter in Norway for more than 1 week. 87 of 212 women asked to participate completed the questionnaire. The physical acts of violence in SVAWS correlated significantly (P<0.001) with both the general health and bodily pain dimensions in SF-36 and global overall health (OH) in WHOQOL-BREF. Most correlations between WHOQOL-BREF and SF-36 were moderate. The WHOQOL-BREF domains explained 46% of the variance in OH and 40% of the variance in the global overall quality of life (OQOL). The SF-36 domains explained 66% of the variance in OH and 27% of OQOL. The mean WHOQOL-BREF and SF-36 scores were all low. The SF-36 correlated better with physical and psychological IPV in this population than the WHOQOL-BREF. The significant correlations between the OH, general health and bodily pain domains and acts of violence show the importance of including questions concerning bodily symptoms in determining the quality of life in a population of abused women.  相似文献
