This work studies the personal experience of volunteering and several antecedent and consequent variables. We studied the effect of the amount of time dedicated to the organization, motivation, social support, integration in the organization, self‐efficacy, and characteristics of the work on a consequent variable of the volunteering experience; that is, burnout, with its 3 components of efficacy, cynicism, and exhaustion. The statistical analysis shows that the time dedicated to volunteering and the extrinsic motivations (i.e., social and career) predicts higher levels of burnout, whereas intrinsic motivations (i.e., values and understanding), life satisfaction, and integration in the organization are negatively related to burnout. 相似文献

In the context of a U.S. dominant masculinity ideology, which devalues men who are not heterosexually identified, many gay, bisexual and questioning (GBQ) adolescent males must develop their own affirming and health-promoting sense of masculinity. In order to promote the well-being of GBQ young men, exploration of their reactions and responses to dominant images of masculinity is needed. We qualitatively analyzed interviews with 39 GBQ African American, Latino, and European American male adolescents (15–23 years old). Participants reported a range of responses to traditional masculinity ideologies, most of which centered on balancing presentations of masculine and feminine characteristics. Negotiation strategies served a variety of functions, including avoiding anti-gay violence, living up to expected images of masculinity, and creating unique images of personhood free of gender role expectations. These data suggest a complex picture of GBQ male adolescents’ management of masculinity expectations and serve as a basis for culturally and developmentally specific HIV prevention programs. 相似文献

Given that a key function of tests is to serve as evaluation instruments and for decision making in the fields of psychology and education, the possibility that some of their items may show differential behaviour is a major concern for psychometricians. In recent decades, important progress has been made as regards the efficacy of techniques designed to detect this differential item functioning (DIF). However, the findings are scant when it comes to explaining its causes. The present study addresses this problem from the perspective of multilevel analysis. Starting from a case study in the area of transcultural comparisons, multilevel logistic regression is used: 1) to identify the item characteristics associated with the presence of DIF; 2) to estimate the proportion of variation in the DIF coefficients that is explained by these characteristics; and 3) to evaluate alternative explanations of the DIF by comparing the explanatory power or fit of different sequential models. The comparison of these models confirmed one of the two alternatives (familiarity with the stimulus) and rejected the other (the topic area) as being a cause of differential functioning with respect to the compared groups. 相似文献

An important trend in contemporary epistemology centers on elaborating an old idea of pragmatist pedigree: theory selection
(and in general the process of changing view and fixing beliefs) presupposes epistemic values. This article focuses on analyzing
the case where epistemic values are indeterminate or when the sources of valuation are multiple (epistemic values like coherence
and simplicity need not order options in compatible ways). According to the theory that thus arises epistemic alternatives
need not be fully ordered by an underlying notion of information-value and therefore the usual economic techniques of optimization cannot be applied in order to compute optimal contractions. But in cases of this sort it is still rational to maximize, i.e. to deem an option as choosable when it is not known to be worse that any other. We present here basic results about
a notion of liberal contraction based on maximizing quasi-orderings. This requires the previous solution of some open problems in the theory of rational
choice functions, namely a full characterization of choice functions rationalizable in terms of maximization of quasi-transitive
relations. We conclude by discussing the problem of what is the adequate feasible set for calculating maximizing solutions
for contraction problems and by considering the epistemological roots of some counterexamples against the most fundamental
axioms on choice functions (like α). While the first part of the paper shows how economic insights can be used to improve our understanding of the principles
of belief formation and change, this final section reverses this strategy by showing the utility of epistemological insights
and techniques for providing invariance conditions capable of regulating the applicability of the pure principles of choice. 相似文献

The article focuses on representing different forms of non-adjunctive inference as sub-Kripkean systems of classical modal logic, where the inference from □A and □B to □A∧B fails. In particular we prove a completeness result showing that the modal system that Schotch and Jennings derive from a
form of non-adjunctive inference in (Schotch and Jennings, 1980) is a classical system strictly stronger than EMN and weaker than K (following the notation for classical modalities presented in Chellas, 1980). The unified semantical characterization in
terms of neighborhoods permits comparisons between different forms of non-adjunctive inference. For example, we show that
the non-adjunctive logic proposed in (Schotch and Jennings, 1980) is not adequate in general for representing the logic of
high probability operators. An alternative interpretation of the forcing relation of Schotch and Jennings is derived from
the proposed unified semantics and utilized in order to propose a more fine-grained measure of epistemic coherence than the
one presented in (Schotch and Jennings, 1980). Finally we propose a syntactic translation of the purely implicative part of
Jaśkowski's system D2 into a classical system preserving all the theorems (and non-theorems) explicilty mentioned in (Jaśkowski, 1969). The translation
method can be used in order to develop epistemic semantics for a larger class of non-adjunctive (discursive) logics than the
ones historically investigated by Jaśkowski. 相似文献

Linking organizational resources and work engagement to employee performance and customer loyalty: the mediation of service climate 总被引:9,自引:0,他引:9
This study examined the mediating role of service climate in the prediction of employee performance and customer loyalty. Contact employees (N=342) from 114 service units (58 hotel front desks and 56 restaurants) provided information about organizational resources, engagement, and service climate. Furthermore, customers (N=1,140) from these units provided information on employee performance and customer loyalty. Structural equation modeling analyses were consistent with a full mediation model in which organizational resources and work engagement predict service climate, which in turn predicts employee performance and then customer loyalty. Further analyses revealed a potential reciprocal effect between service climate and customer loyalty. Implications of the study are discussed, together with limitations and suggestions for future research. 相似文献

Memory consists of several phases or processes that can be influenced by many factors, including the individual's circadian rhythm and the time of day at which tests are performed. The present objective was to evaluate the performance on memory tests of different chronotypes during the morning and the evening shifts. Subjects (21 men and 26 women, between the ages of 20 and 35 yr.) were evaluated for memory and metamemory differences in the morning and in the afternoon, using a battery of neuropsychological tests composed of the Word List with Emotional Content, Visual Memory, Scale-Semantic Memory, Digit Span, Word-Pairs Associated, Verbal Fluency Test, and Metamemory questionnaire. In the evening shift, there was a statistical difference among chronotypes on the Word List with Neutral Content and on the Verbal Fluency Test. In the morning, there were no statistically significant differences; however, the morning-type subjects had higher scores on the metamemory tests (p<.01), while the evening-type subjects had higher scores in the afternoon (p<.01). In spite of their perception, on Word-Pairs Associated and Word List with Emotional Content, the subjects, independently of their chronotype, showed better performance by the evening than by the morning shift. These results highlight the importance of controlling the shift of day and chronotype in studies with the objective of exploration of human performance. 相似文献

This study analyzes how dispositional goal orientations and perception of different motivational climates are related to the students' perception of sex-related egalitarian treatment and the appearance of disciplined or undisciplined behaviors in physical education classes. Analyses showed that ego orientation is a predictor of undisciplined behavior. Task orientation was positively associated to discipline. The perception of task-involving motivational climate is related to the students' perception of equal treatment. On the contrary, the perception of ego-involving climate has been linked positively to the prediction of the perception of sex discrimination in physical education classes and negatively to the perception of equality and the appearance of disciplined behavior. This study discusses the implications of these results related to teaching instructional actions in physical education classes. 相似文献

In a non-clinical group of 130 children (65 boys and 65 girls), we evaluated the relationships between psychological problems using the Child Behavior Checklist (CBCL) reported by parents, the Inattention Overactivity With Aggression (IOWA) scale reported by teachers, individual factors (Intellectual quotient [IQ], temperament and heart rate) and environmental factors (stress events, mother's profession and being or not being an only child). We found no differences between the sexes in the prevalence of total psychological problems in the clinical range, but girls had significantly more borderline total problems than boys. Girls tended to have more externalizing problems than boys. In boys, there were more links between individual and environmental factors and psychological problems, especially externalizing problems. A high score in psychological problems assessed by the CBCL affected the school performance of boys and the social performance of girls. For boys, IQ was significantly lower when the score for total behavioral problems was higher, and for girls IQ was significantly lower when the score for externalizing problems was higher. Understanding the different levels of vulnerability of the sexes at different periods of development may help to improve the treatment children in this age group receive. 相似文献
