Group decision making is very significant in a broad variety of settings. This paper deals with committees that make binary decisions and addresses the question of whether informative decisions can be assumed within this framework. We show that when using the optimal decision rule, informative decision making is a Nash equilibrium. Thus we justify the assumption of informative decision making and provide support for the relevance of assumptions such as independent decision making, when using the optimal decision rule. 相似文献

The present study was designed to examine the correlation between attachment patterns of adults and reactions to separations from their significant others on both a phenomenological and a representational level. Cluster analysis technique was used to classify 137 college students into four attachment pattern categories: secure, avoidant, ambivalent, and controlling (compulsive care giver). On the phenomenological level, the current relationships of the subjects with their parents and romantic partner were assessed, in order to explore how they manage the developmental task of separation from one's parents. On the representational level we assessed, using a projective test (the SAT) subjects' responses to mild and severe separations. As expected, subjects with different attachment patterns coped with separations according to their attachment style. For example, secure subjects coped well with this developmental task. They tended to live outside the parental home and to attribute the highest significance to their romantic partner while sustaining close communication with their mother. Ambivalent subjects also tended to live outside their parental home but were all single and reported less committed and close relationships with romantic partners. On a representational level they reacted with strong anxiety, rejection, and self-blame to separations and even mild separations elicited strong attachment reactions. Avoidant subjects tended to refrain from dealing with the developmental task of separation, while controlling subjects were characterized by their use of mechanisms of reaction formation. Overall the results underscore the importance of considering attachment patterns of adults in our attempts to understand coping with the developmental task of separation.Received Ph.D from Tel-Aviv University, Israel.

Variation in the timing of pubertal maturation may result in behavioral differences among early, mid-, and late maturers. Using data from the National Health Examination Survey, a national probability sample of children and youth aged 12–17, we investigated the relationships between maturational timing and body image, school behavior, and deviance. In terms of body image, the early maturing boys were the group most satisfied with height and weight. The early maturing girls were most dissatisfied with weight, with 69% wishing to be thinner. This great dissatisfaction with weight reported by early maturing girls is probably not an affect of early maturation, but a concomitant of maturation in general. The majority of girls became dissatisfied with their weight as they matured, and females from the higher social groups were more likely to want to be thinner than females from lower groups. Thus, a normal developmental process is being viewed negatively by females and positively by males. Male early maturers more often had deviant behavior, but there were no consistent findings for girls. There was no effect of maturational timing on teacher reports of school absence, adjustment, popularity, need for discipline, or grade repetition.This research was supported by the Stanford Center for the Study of Youth Development and by the Robert Wood Johnson Foundation.Received M.D. from The Medical College of Pennsylvania.Received Ph.D. in anthropology from Stanford University.Received Ph.D. in sociology from the University of Chicago.Received M.D. from Columbia College of Physicians and Surgeons.Received Ph.D. in psychology from Harvard University. 相似文献

For some years now, the phenomenon known as The New Right has been developing in the United States, and although there is growing recognition of its destructiveness, there is little understanding of its real nature.At first examination The New Right seems to hold contradictory or incongruous beliefs and values, but placed within the context of fascism, authoritarianism, and ultimately masculism, the whole system of doctrine begins to make sense.While ostensibly supporting traditionalist principles of Christianity, American patriotism, and free enterprise economics, The New Right really encompasses groups of individuals unable to negotiate the uncertainties of lived existence and the fear of death and non-being. Drawn, therefore, to the consciousness of authoritarian rigidity, they seek to reinforce a flimsy structure of salvation by insisting upon absolute agreement with their perspective.The entire system of thought and behavior rests upon an alienation from nature lodged in patriarchal, masculist consciousness.Understanding this structure helps us to deal more effectively with The New Right and reinforces our will to oppose it. 相似文献

Research evidence concerning product characteristics, consumer characteristics and product purchase situations is examined. Assumptions underlying consumer policy strategies directed at enhancing the ability of consumers to protect themselves and those strategies aimed at product quality control are analyzed in light of the evidence. Alternative policy strategies are analyzed for consumer incentives and with respect to product characteristics, consumer characteristics and product purchase situations. Recommendations regarding consumer protection policy strategies and for research concerning alternative policy strategies are provided. Illustrative policy strategies are included. 相似文献

This article aims to assess why technology such as improved crop varieties has not taken off in Tanzania in spite of substantial efforts, and to consider what role policy plays in that regard. Few farmers use improved varieties due to reasons such as affordability in relation to the low profitability of farming; high risk, including fake seed in the market; and unpredictable policies and marketing opportunities. Effective governance is needed for agriculture to be transformed in the direction stated in national policy documents, but weak institutions and the collective interests of farmers not being sufficiently recognised hinder the likelihood of necessary technological changes happening. 相似文献
