Fehr and Schmidt (FS) introduced an influential social utility function for individuals in interpersonal contexts that captures self-centered inequity aversion. The value of this social utility function lies in its exceptionally good balance between parsimony and fit. This paper provides a preference foundation for exactly the model of FS with preference conditions that exactly capture the exceptionally good balance of FS. Remarkably, FS is a special case of Schmeidler’s rank-dependent utility for decision under uncertainty.  相似文献

Many experiments have demonstrated that when evaluating payoffs, people take not only their own payoffs into account, but also the payoffs of others in their social environment. Most of this evidence is found in settings where payoffs are riskless. It is plausible that if people care about the payoffs of others, they do so not only in a riskless context, but also in a risky one. This suggests that an individual’s decision making under risk depends on the risks others in his or her environment face. This paper is the first to test whether individuals’ risk attitudes are affected by the risks others face. The results show that risk attitudes appear to be less affected by others’ risks than expected, even though the same subjects do show concerns for inequality in a riskless setting. Interestingly, we find that people prefer risks to be independent across individuals in society rather than correlated.  相似文献

Background

Muscular strength is associated with functional ability in elderly, and older adults are recommended to perform muscle-strengthening exercise. Understanding how improved muscle strength and -mass influence general and specific domains of quality of life is important when planning health promotion efforts targeting older adults. The aims of the present study were to describe changes in health-related quality of life (HRQOL) in older men participating in 12 weeks of systematic strength training, and to investigate whether improvements in muscle strength and muscle mass are associated with enhancements in HRQOL.

Methods

We recruited 49 men aged 60–81 years to participate in an intervention study with pre-post assessment. The participants completed a 12-week strength training program consisting of three sessions per week. Tests and measurements aimed at assessing change in HRQOL, and changes in physical performance (maximal strength) and physiological characteristics. HRQOL was measured using the 12-item short-form survey (SF-12). Muscle mass was assessed based on changes in lean mass (leg, trunk, arm, and total), and strength was measured as one-repetition maximum in leg extension, leg press, and biceps curl.

Results

Two of the eight HRQOL SF-12 scores, role physical and general health, and the physical component summary scores, increased significantly during the intervention period. Small significant positive correlations were identified between improvements in muscle strength, and better physical and social function. Moreover, a significant increase in total muscle mass was seen during the intervention period.

Conclusions

The positive, findings from this study would suggest that systematic strength training seems to be a beneficial intervention to improve HRQOL, muscle strength and muscle mass in older men.

The objectives of the study are: (a) to provide the first prevalence estimates of pathological gambling among Brazilian adolescents using an age-specific instrument in a nationally representative sample; (b) to investigate the extent to which adolescents participate in gambling activities in a developing country; and (c) to correlate different levels of gambling behavior with demographic variables. Multistage cluster sampling selected 3,007 individuals over 14 years of age from Brazilian household population. A total of 661 participants were between 14 and 17 years old. The Lie/Bet Questionnaire and the DSM-IV-MR-J were used for assessing problem and pathological gambling. 2.8% scored positive on the screening questionnaire, while 1.6% were classified as problem and pathological gamblers. Factors associated with problem and pathological gambling were male sex, not currently studying and considering religion as not important. Less than 4 months elapsed between the age of regular gambling involvement and the first gambling problem. Prevalence rates were quite similar from recent studies which used nationally representative samples. The association of problem and pathological gambling with male sex, school drop-out and low religiosity supports the Problem Behavior Theory. The fast progression to problem gambling adds evidence that adolescents may be more vulnerable to the effects of gambling.  相似文献

This paper measures racial inequalities in the US using a multidimensional ‘wellbeing’ approach that simultaneously considers the distributions of income, health and education. The primary objective is to examine trends in US wellbeing inequality with an emphasis on changes in racial composition. Data is taken from 1990 to 2007 and we observe increases in income inequality, a decline in education inequality and unchanged health inequality over the period. Taken together, these results show a slight increase in the dispersion in multidimensional wellbeing. Stratifying by racial groups shows that this increase is due to widening intra-racial inequalities while inter-racial differences remained unchanged. The method is also used to evaluate wellbeing across groups and we estimate black wellbeing to average around 76 % of whites, while persons from other races average approximately 93 %. Some other changes in composition occur through time and the results are shown to be robust to a number of changes in parametric weightings.  相似文献

Abstract

Contextualized in the critical pedagogies of universal design for learning (UDL) and social justice education, our study aimed to equip teacher candidates (TCs) to provide students with equitable access to learning social studies content knowledge, skills, and processes as a way to equally empower all students to be civically engaged, and thus to disrupt the social reproduction of empowering privileged students and disempowering marginalized ones in the public schools. An earlier study indicated that our TCs did not transfer or generalize the UDL framework from foundation courses to subsequent classes or in practice. This case study describes how and in what ways elementary education faculty used a transdisciplinary approach, integrating the UDL framework taught in the foundation’s course into a social studies methods course to facilitate TCs’ continued learning and application of theory into practice. The results of this case study suggest that TCs that TCs had not yet internalized the UDL framework or critical consciousness and that these must be intentionally transferred and generalized to new coursework by the faculty on a consistent, ongoing basis.  相似文献

The group manager, who has close contact with his employees, is especially adequate to support these according to their interests and abilities. In this study we identified 12 leadership behaviors that enhance employees?? competencies and career advancement by analyzing 36 interviews with (potential) managers from companies operating in the fields of science and technology. These behaviors contain both ways of supporting through direct contact (feedback, training measures, promotion, trust, instrumental and informational support, management by objectives, emotional support and appraisal, recognizing potential, role model behavior) as well as ways of supporting by providing a competence and career enhancing job design (delegation of challenging tasks, job control, person-job-fit). The outcome shows that that job design is a key factor. In addition, the company??s role turned out to be another major factor influencing the employee??s professional progress. Practical recommendations for enhancing employee??s motivation and empowerment are given. These can also be the base for future related additional research.  相似文献
