Abstract We investigated the transituational coherence of coping strategy use by collecting coping data on multiple occasions, and assessing the effects of aggregation over varying numbers of occasions. Study 1 examined the effects of aggregating daily coping reports over three- and six-day periods. Study 2 extended the results of Study 1 by assessing the extent to which aggregation increased the correlation between a dispositional coping measure and daily coping reports. Both studies strongly supported the hypothesis that aggregation would enhance the consistency of coping preferences, suggesting some degree of coherence within the domain of coping strategy used. Aggregated coping reports correlated with each other at significantly higher levels (ranging from 0.46 to 0.77 in Study 1 and from 0.65 to 0.95 in Study 2), than unaggregated coping reports (ranging from ?0.12 to 0.30 in Study 1 and from 0.12 to 0.53 in Study 2). Study 2 also showed that aggregated daily reports were better predictors of subsequent coping than scores derived from a standard dispositional coping survey. 相似文献

What is it to “value” something, in the semi‐technical sense of the term that Gary Watson establishes? I argue that valuing something consists in caring about it. Caring involves not only emotional dispositions of the sort that Agnieszka Jaworska has elaborated, but also a distinctive cognitive disposition – namely, a (defeasible) disposition to believe the object cared about to be a source of agent‐relative reasons for action and for emotion. Understood in this way, an agent's carings have a stronger claim to “speak for” her as her values than do other attitudes that have been proposed for this role. In particular, an agent's carings establish more robust psychological continuities and cross‐temporal connections than do self‐governing policies of the sort that Michael Bratman has described; and they forge diachronic coherence not just in her deliberation and action, as self‐governing policies do, but also in her cognitive and emotional life. An agent's carings thus help to constitute her identity as a temporally persisting subject. Self‐governing policies are at best ersatz‐values, which an agent may choose to adopt when she finds that her proper values – her cares – leave her course underdetermined. 相似文献

Subjects judged the disutility of health conditions (e.g. blindness) using one of them (e.g. blindness+deafness) as a standard, using three elicitation methods: analog scale (AS, how bad is blindness compared to blindness+deafness?); magnitude estimation (ME, blindness+deafness is how many times as bad as blindness?); and person trade‐off (PTO, how many people cured of blindness is as good as 10 people cured of blindness+deafness?). ME disutilities of the less bad condition were smallest, and AS was highest. Interleaving PTO with ME made PTO more like ME. AS disutilities were inconsistent with direct judgments of differences between pairs of conditions. ME and PTO judgments were internally inconsistent: e.g. the disutility of one‐eye‐blindness relative to blindness+deafness was larger than predicted from comparison of each to blindness. Consistency training reduced inconsistency, increased agreement between AS and PTO, and transferred from one method to the other. The results support the use of consistency checks in utility elicitation. Copyright © 2001 John Wiley & Sons, Ltd. 相似文献

Previous research within a dual‐process cognitive‐motivational theory of ideology and prejudice has indicated that dimensions of generalized prejudice are structured around attitudes towards dangerous, derogated and dissident groups, and that these prejudice dimensions are differentially predicted by the ideological attitudes of Right‐Wing Authoritarianism (RWA) and Social Dominance Orientation (SDO). However, to date, these findings have been restricted to New Zealand samples. We describe two studies examining whether the structure of prejudiced attitudes and the differential prediction by RWA and SDO replicate in the Brazilian context, incorporating context‐relevant examples of each group—politicians, those from the northeast region of Brazil, and environmentalists. Results broadly supported the three‐factor structure of dangerous, derogated, and dissident groups. Consistent with previous research, regression and structural equation analyses showed that RWA explained prejudice against dangerous groups, SDO explained prejudice against derogated groups, and both RWA and SDO explained prejudice against dissident groups. This research provides some evidence for the generalizability of the three‐dimensional structure of generalized prejudice and differential prediction by RWA and SDO.

The vast amount of information that must be considered to solve inherently ill‐structured and complex strategic problems creates a need for tools to help decision makers (DMs) recognize the complexity of this process and develop a rational model for strategy evaluation. Over the last several decades, a philosophy and a body of intuitive and analytical methods have been developed to assist DMs in the evaluation of strategic alternatives. However, the intuitive methods lack a structured framework for the systematic evaluation of strategic alternatives while the analytical methods are not intended to capture intuitive preferences. Euclid is a simple and yet sophisticated multiobjective value analysis model that attempts to uncover some of the complexities inherent in the evaluation of strategic alternatives. The proposed model uses a series of intuitive and analytical methods including environmental scanning, the analytic hierarchy process (AHP), subjective probabilities, and the theory of displaced ideal, to plot strategic alternatives on a matrix based on their Euclidean distance from the ideal alternative. Euclid is further compared to the quantitative strategic planning matrix (QSPM) in a real world application. The information provided by the users shows that Euclid can significantly enhance decision quality and the DM's confidence. Euclid is not intended to replace the DMs, rather, it provides a systematic approach to support, supplement, and ensure the internal consistency of their judgments through a series of logically sound techniques.

The generalized logit–linear item response model (GLLIRM) is a linearly constrained nominal categories model (NCM) that computes the scale and intercept parameters for categories as a weighted sum of basic parameters. This paper addresses the problems of the identifiability of the basic parameters and the equivalence between different GLLIRM models. It is shown that the identifiability of the basic parameters depends on the size and rank of the coefficient matrix of the linear functions. Moreover, two models are observationally equivalent if the product of the respective coefficient matrices has full column rank. Finally, the paper also explores the relations between the parameters of nested models. I would like to express my gratitude to the editor and three anonymous reviewers for their helpful suggestions on earlier versions of the paper.

This research explored the relative contributions of subjective perceptions of body weight and body shape/proportion, as well as objective measures of body mass index (BMI) and waist-to-hip ratio (WHR) to disordered eating, exercise involvement, and body image. One hundred and fifty-eight female university students completed questionnaires and provided body measurements for this study. Although an interaction between BMI and WHR was found for some measures (i.e., Eating Disorder Examination Questionnaire total and subscale scores), results indicated that BMI was consistently the better objective predictor of disordered eating and body image. Subjective perceptions of body weight and, to a lesser extent, body shape, were found to account for the greatest proportion of variance in the dependent measures (disordered eating, body esteem, and body dissatisfaction). Overall, these results offer more support for sociocultural theories emphasizing the importance of thinness for women, than evolutionary theories emphasizing the role of WHR. 相似文献
