We show that Bayesian ex post aggregation is unstable with respect to refinements. Suppose a group of Bayesians use ex post
aggregation. Since it is a joint problem, each agent's problem is captured by the same model, but probabilities and utilities
may vary. If they analyze the same situation in more detail, their refined analysis should preserve their preferences among
acts. However, ex post aggregation could bring about a preference reversal on the group level. Ex post aggregation thus depends
on how much information is used and may keep oscillating (“flipping”) as one keeps adding more information.

Because of the close connection between culture and language, a number of writers have suggested that bilinguals will differ in their behavior because of differences in the degree of assimilation of different cultures in the same individual. We tested this notion by obtaining data from bilingual (English and Hindi) college students in India using a well-studied cross-cultural research paradigm involving emotional perception. Subjects judged universal facial expressions of emotion in two separate sessions, one conducted entirely in English, the other in Hindi. In each session, they judged which emotion was being portrayed, and how intensely. Subjects recognized anger, fear, and sadness more accurately in English than in Hindi. They also attributed greater intensity to female photos of anger when rating in Hindi, but attributed greater intensity to female photos of sadness when rating in English. These findings were discussed in relation to the theoretical connection between culture and language. 相似文献

This paper, the third in a series concerned with family therapy in cases involving children at risk of abuse, describes an approach to maximising parents' interest and commitment to therapy. After overviewing the difficulties faced by therapists in working with parents who are notorious for their ‘resistance’, we provide guidelines for minimising the negative consequences of notification and for constructing therapeutic leverage in order to elicit and maintain parents' motivation throughout the course of therapy. 相似文献

For two-parameter exponential populations with the same scale parameter (known or unknown) comparisons are made between the location parameters. This is done by constructing confidence intervals, which can then be used for selection procedures. Comparisons are made with a control, and with the (unknown) “best” or “worst” population. Emphasis is laid on finding approximations to the confidence so that calculations are simple and tables are not necessary. (Since we consider unequal sample sizes, tables for exact values would need to be extensive.) 相似文献
