In this paper, we consider various ways in which aesthetic value bears on, if not serves as evidence for, the truth of independent statements in set theory.

... the aesthetic issue, which in practice will also for me be the decisive factor—John von Neumann, letter to Carnap, 1931  相似文献

Two studies addressed the role of Black meta‐perception of acculturation attitudes on the relation between minority acculturation attitudes and their social adjustment (school achievement and perceived quality of intergroup relations). Participants in both studies were Black Lusophone adolescents living in Portugal. Study 1 (N = 140) indicated that participants' attitude regarding the host culture was positively correlated with their school achievement and to their evaluation of intergroup relations. It also indicated that participants' meta‐perception of majority attitude add to the explained variance of participants' social adjustment. Study 2 (N = 62) manipulated the perceived majority high/low support of immigrants' learning the host culture. The dependent variable (DV) was perceived quality of intergroup relations. Only in the low support condition were participants' attitudes towards the host culture positively related to perceived quality of Black–White relationships. These results suggest that perceived social context is central to understand the relationship between minority adolescents' acculturation attitudes and key dimensions of their adjustment to host societies.  相似文献

Recent evidence regarding the relationship between social support and depression in elderly people shows the important role of ethnicity. This research describes the characteristics of social support in a sample of elderly people aged 60 and above living in northern Chile (n = 493), and analyzes the differences in the relationship between social support and depression between an indigenous group (Aymara population, n = 147) and a nonindigenous group (white, Caucasian, mestizo, n = 346). Various dimensions of social support were considered: structural elements, functional social support according to source, and community participation. The results show the existence of significant differences in the characteristics and dimensions of social support depending on sex, ethnicity, and marital status. Further, the central role of the family group is observed for both Aymara and nonindigenous elderly people. The hierarchical regression models obtained result in notable differences in the role of the structural, functional, and community elements of support in explaining depression for the ethnic groups considered.  相似文献

The Yale–Brown Obsessive–Compulsive Scale for children and adolescents (CY–BOCS) is a frequently applied test to assess obsessive–compulsive symptoms. We conducted a reliability generalization meta-analysis on the CY–BOCS to estimate the average reliability, search for reliability moderators, and propose a predictive model that researchers and clinicians can use to estimate the expected reliability of the CY–BOCS scores. A total of 47 studies reporting a reliability coefficient with the data at hand were included in the meta-analysis. The results showed good reliability and a large variability associated to the standard deviation of total scores and sample size.  相似文献

Well-being is one of the keys to successful and optimal development across the lifespan. Based on the idea that development involves changes in individuals’ adaptive capacity to meet their needs over time, the changes that occur in the second half of life require effort to adapt to the new reality. This study used a structural model to test the effects of coping strategies and resilience on well-being in a sample of 305 mid-life adults. Several constructs were measured: coping strategies, resilience, and well-being. A final model was obtained with good fit indices; psychological well-being was positively predicted by resilience and negatively by emotional coping. Moreover, positive reappraisal and avoidance form part of both coping strategies (problem-focused and emotion-focused). Considering the characteristics of the model, educational intervention programs could be developed to promote skills that favor good adaptation at this stage in the life cycle and contribute to promoting successful aging.  相似文献

Social‐perception dimensions may explain human‐animal relationships because animals show intent toward humans (social perception's warmth dimension) and, consequently, their potential effect on humans is relevant (competence dimension). After reviewing current literature about perceptions of animals’ ascribed intentions and abilities, three studies tested the Stereotype Content Model (SCM) (Fiske, Cuddy, Glick, & Xu, 2002) and the Behaviors from Intergroup Affect and Stereotypes Map (Cuddy, Fiske, & Glick, 2007) regarding animal targets. Study 1 found a four‐cluster SCM structure. Warmth and competence judgments predicted specific emotions and behavioral tendencies toward animals (Study 2). Study 3 supported associations between animals and social groups based on their respective perceived warmth and competence. Taken together, results showed the relevance of SCM dimensions for social perception of animals.  相似文献
