Ethno/racial affiliation,trust, and identification in higher education: the mediating role of perceived injustice in the classroom

Social Psychology of Education - The present study contributes to a vast body of empirical research on the importance of the sense of justice in education. It examines the mediating role of...     

Group heterogeneity and tolerance: The moderating role of conservation values

Does diversity promote tolerance? We propose that reactions to group heterogeneity depend on individual value priorities. In three studies we investigate how values moderate the effect of raising the salience of group heterogeneity (versus homogeneity) on tolerance. As hypothesized, the findings indicate that conservation values moderate the effects of the saliency of the group's heterogeneity. People high on conservation values were more tolerant when the group's homogeneity was made salient than when its heterogeneity was made salient. People low on conservation were either insensitive to information on the group's heterogeneity (Studies 1 and 2), or were more tolerant when the group's heterogeneity was made salient than when its homogeneity was made salient (Study 3). Values are also directly associated with tolerance: conservation values (as well as SDO and RWA in Study 3) were negatively associated whereas openness-to-change and self-transcendence values were positively associated with tolerance. These findings indicate the importance of integrating individual and contextual variables in theories of group processes.     

Immigrant identity of Israeli adolescents from Ethiopia and the former USSR: culture‐specific principles of organization

The study examines how a sample of 210 high‐school immigrant students (ages 14–15) from Ethiopia and the former USSR socially represent their notion of what klitat aliyah (successful adaptation to Israel) means. Prevalent relevant theories—Berry's model of Acculturation Tendencies (BAT), Social Identity Theory (SIT) and Social Comparison Theory (SCT)—suggest three kinds of patterns by which minority or socially weak groups deal with these kinds of situations. These underlying patterns were tested by a 47‐item questionnaire (with a 4‐point Likert‐like scale), constructed from immigrant narratives regarding their klitat aliyah according to SIT, SCT and BAT categories of adaptation strategies. A Guttman non‐parametric Similarity Structure Analysis (SSA) revealed four‐facet organization of items for both males and females in both sub‐samples. These facets, which reflected social representations of Israeli society, were dubbed: Extended Identity, Rivalry Identity, Secluded Identity and Identity Loss. Results did not confirm the underlying categorization of strategies suggested by SIT and SCT, and partially replicated those suggested by BAT. Copyright © 2002 John Wiley & Sons, Ltd.     

An analytic tableau calculus for a temporalised belief logic

A tableau is a refutation-based decision procedure for a related logic, and is among the most popular proof procedures for modal logics. In this paper, we present a labelled tableau calculus for a temporalised belief logic called TML⁺, which is obtained by adding a linear-time temporal logic onto a belief logic by the temporalisation method of Finger and Gabbay. We first establish the soundness and the completeness of the labelled tableau calculus based on the soundness and completeness results of its constituent logics. We then sketch a resolution-type proof procedure that complements the tableau calculus and also propose a model checking algorithm for TML⁺ based on the recent results for model checking procedures for temporalised logics. TML⁺ is suitable for formalising trust and agent beliefs and reasoning about their evolution for agent-based systems. Based on the logic TML⁺, the proposed labelled tableau calculus could be used for analysis, design and verification of agent-based systems operating in dynamic environments.     

Internet access and use among homeless and indigent drug users in Long Beach, California.

There has been a growing interest in using the Internet to access a variety of populations for prevention education and health care. It is not clear that this is viable for homeless and other marginalized populations. The purpose of this study was to describe Internet access and use among a sample of homeless and indigent drug users. A brief questionnaire was developed to assess computer ownership, use, email, and Internet access and use. Participants were recruited through a community-based human immunodeficiency virus (HIV) prevention program. 265 participants completed the questionnaire. While 55% had ever used a computer in their lifetime, only 25% had ever owned a computer, 24% had ever had their own email account, 33% had access to a working computer in the last 30 days, 10% had sent or received email in the last 30 days, and 19% had surfed or accessed information on the Internet in the last 30 days. Logistic regression predicting lifetime use of a computer showed predictive factors of having completed high school (Odds Ratio [OR] = 4.5; 95% Confidence Interval [CI] = 2.41, 8.38) and number of days used amphetamines in the last 30 days, per 5 days of use (OR = 1.64; 95% CI = 1.18, 2.27). Inversely related were age, per 5 years of age (OR = 0.78; 95% CI = 0.65, 0.93) and number of days used marijuana in the last 30 days, per 5 days of use (OR = 0.97; 95% CI = 0.76, 0.99). Very low access and usage suggest that Internet-based public health education models be reexamined for this population. The association with amphetamine use may indicate a facilitating effect of amphetamine by heightening awareness and increasing wakefulness.     

Parental Support and Adolescent Motivation for Dieting: The Self-Determination Theory Perspective

This article focuses on parents’ role in overweight adolescents’ motivation to diet and successful weight loss. The study employed Self-Determination Theory (SDT) as the theoretical framework (Deci & Ryan, 2000, 2011). Ninety-nine participants (ages 20–30) who had been overweight during adolescence according to their Body Mass Index (BMI mean = 25, SD = 1.6), completed retrospective questionnaires about their motivation to diet and their parents’ behavior in the context of dieting. Findings from a structural equation modeling analysis suggested that participants who viewed their parents’ as more need-supportive demonstrated more autonomous motivation to diet, which, in turn, contributed to their successful weight loss. The findings highlight the importance of parental support of adolescents’ psychological needs in the quality of their motivation to diet. This is an important insight for parents and professionals who aim to encourage more constructive parent involvement in adolescents’ dieting and well-being.     

The factor structure of the Social Axioms Survey II (SASII) in the South African context

The objective of this study was to validate the new Social Axioms Survey II (SASII). The study sample comprised university students (n = 793) as well as their family members and friends (n = 645). Confirmatory factor analysis (CFA) following an initial exploratory factor analysis yielded a five-factor model: social cynicism, social complexity, reward for application, religiosity, and fate control. The findings of this study support the use of the new SASII in South Africa for research purposes.
