Empirical analysis of data drawn from the European Social Survey reveals that—after individual characteristics are controlled for—women engaging in market work and housework have similar life satisfaction levels. Complementing the micro-level data from the survey with country-level variables, namely GDP per capita and gender inequality (measured by the World Economic Forum’s Global Gender Gap Index, GGGI), we estimate a multilevel regression model to shed light on the contextual factors of the life satisfaction of women in Europe. We find that working women’s well-being relative to housewives is greater in countries where the GGGI indicates a smaller gender gap, i.e. where women are in a better position in terms of equality with men in the public domains. We interpret this finding to mean that the so-called ‘paradox of declining female happiness’ is in part due to persistent gender roles which appear to have a larger impact on the well-being of working women.  相似文献

Emerging adults share the positive events in their lives with their friends, a process that is related to higher levels of happiness when they perceive their friends’ responses as more positive and less negative. What might explain this association? The four studies (N = 2997) in this research tested the proposal that positive friendship experiences mediate the relationship between perceived responses to capitalization attempts (PRCA) and happiness. Study 1 showed that same-sex friendship quality mediated the relationship between PRCA and happiness. Study 2 supported the model for cross-sex friendships. Study 3 tested the generalizability of the model for the immediate social network of emerging adults and showed that the model was only applicable to best friendships. Study 4 documented that satisfaction of basic psychological needs in a same-sex friendship was another mediator of the PRCA-happiness link. Although the friendship experiences and PRCA scores of women were higher compared to men in every study, the associations of PRCA with friendship experiences and happiness were generally similar and the model was supported for both men and women. The implications of the findings were discussed and suggestions for future research were provided.  相似文献

A recent study found that guppies (Poecilia reticulata) can be trained to discriminate 4 versus 5 objects, a numerical discrimination typically achieved only by some mammals and birds. In that study, guppies were required to discriminate between two patches of small objects on the bottom of the tank that they could remove to find a food reward. It is not clear whether this species possesses exceptional numerical accuracy compared with the other ectothermic vertebrates or whether its remarkable performance was due to a specific predisposition to discriminate between differences in the quality of patches while foraging. To disentangle these possibilities, we trained guppies to the same numerical discriminations with a more conventional two-choice discrimination task. Stimuli were sets of dots presented on a computer screen, and the subjects received a food reward upon approaching the set with the larger numerosity. Though the cognitive problem was identical in the two experiments, the change in the experimental setting led to a much poorer performance as most fish failed even the 2 versus 3 discrimination. In four additional experiments, we varied the duration of the decision time, the type of stimuli, the length of training, and whether correction was allowed in order to identify the factors responsible for the difference. None of these parameters succeeded in increasing the performance to the level of the previous study, although the group trained with three-dimensional stimuli learned the easiest numerical task. We suggest that the different results with the two experimental settings might be due to constraints on learning and that guppies might be prepared to accurately estimate patch quality during foraging but not to learn an abstract stimulus–reward association.  相似文献

Seat belts are effective safety devices for protecting car occupants from injuries and fatalities in road vehicle accidents. Seat belt use has been reported to be related to some health and driving-related behaviors. The aim of the present study was to investigate to what degree seat belt use can be seen as health behavior or driver behavior. Participants were 252 licensed Turkish drivers (180 males, 72 females) with the mean age of 30.8 (SD = 12.15). A questionnaire including questions related to health-related behaviors, driver behaviors and seat belt use was used. Results of factor analysis showed that seat belt use in front seat grouped with driver behaviors (e.g., driving errors and violations) but not with health-related behaviors (e.g., healthy diet and sports participation). Regression analyses showed that seat belt use in back seat; and, regular walking and adequate sleep were positively related to seat belt use in front seat, whereas being male, driving errors and smoking frequency were negatively related to seat belt use in front seat. The present findings suggest that seat belt use can be considered in the context of driver behaviors such as driving errors and violations.  相似文献

The aim of this study was to evaluate the relationship between three perceived parental attitudes and shyness, testing self-esteem and fear of negative evaluation as mediators. The study used a total of 492 undergraduate students in Turkey. Data was collected through measures of shyness, fear of negative evaluation, self-esteem, and perceived parental attitudes. The proposed model was estimated using path analysis. Goodness of fit statistics showed that the model fit the data well. Results indicated that parental acceptance/involvement predicted self-esteem; perceived parental strictness/supervision predicted fear of negative evaluation; and perceived parental psychological autonomy predicted self-esteem. Self-esteem partially mediated the relationship between parental acceptance/involvement and shyness, whereas it fully mediated the relationship between parental psychological autonomy and shyness. Fear of negative evaluation fully mediated the relationship between parental strictness/supervision and shyness. In addition, the relationship between self-esteem and shyness was partially mediated by fear of negative evaluation. The findings provided evidence for the propositions that parental attitudes are important in the development of self-image and fears of rejection which result in the experience of shyness.  相似文献

The author investigated the contribution of perfectionism to life satisfaction among Turkish adolescents. The analyses revealed that high standards and orderliness/organization were positive predictors of life satisfaction, whereas the discrepancy between one's standards and one's actual performance was a negative predictor of life satisfaction. El autor investigó la contribución del perfeccionismo a la satisfacción vital entre adolescentes turcos. Los análisis revelaron que las expectativas elevadas y el orden/organización fueron indicadores de predicción positivos de la satisfacción vital, mientras que la discrepancia entre las expectativas propias y el rendimiento real fue un indicador de predicción negativo de la satisfacción vital.  相似文献

Purpose  The aim of this study was to systematize findings in role stress research into original and conceptually important abstract higher-order constructs and to develop and test a comprehensive structural equation model that examined such expanded conceptualizations of antecedents and consequences to entrepreneur role stress. Design/Methodology/Approach  Model tests were performed on data from a sample of 282 Swedish entrepreneurs (a usable rate of 22.5%) engaged in their first-year of venture activities. We used structural equation modeling, mediation tests and tests for common method bias to test the appropriateness of the model. Findings  We found that role stress can be explained by expansions of lower-ranked, less abstract constructs embedded in a multiple-indicator model of venture technology, venture environment, and entrepreneur personality. The analysis confirmed that role stress is an important mediator and that it has pronounced relationships to expanded conceptualizations of role-related rewards and exhaustion. Implications  This study advance role stress theory and existing knowledge about entrepreneurs and entrepreneurship when it introduces role stress and suggests it mediates the effects from personality traits, organizational and environmental characteristics, on higher-order conceptualizations of rewards and exhaustion. Originality/Value  With contributions from several distinct disciplines over a half decade, prior research has not paid much attention to show how role stress research can benefit from more abstract conceptualizations and empirical evaluation. By synthesizing and developing expanded higher-level conceptualizations that link diversities, we show that expanded conceptualizations effectively enable to introduce role stress to entrepreneurs and entrepreneurship.  相似文献

This study reports three experiments which demonstrate path dependency in risky intertemporal choice. Consider a lottery to be resolved and paid in a future time period. One can obtain the present value of this lottery in three different ways: (1) eliciting directly the present certainty equivalent (CE) of the future lottery (direct path); (2) eliciting the future CE and then discounting this amount to the present (risk‐time path); and (3) eliciting the present value of the risky prospect and then determining the CE of this current lottery (time‐risk path). Standard rational choice models such as the discounted expected utility model, assume a multiplicative model, where all three methods mentioned above would yield the same value. We conducted three studies to examine if this is the case: Experiments 1 and 2 were based on a set of matching‐task questions and Experiment 3 used a process‐tracing design to analyze the natural sequence of decision making by the subjects. These three studies show that the evaluation of future gambles is path‐dependent. The present values elicited under the time‐risk and direct paths are, on average, higher than those reported under the risk‐time path. In addition, we found evidence for a two‐stage evaluation of risky future prospects: When evaluating a future gamble, individuals first assess the present value of the gamble (time discounting) and then they determine a certainty equivalent (probability discounting).

Decision makers and forecasters often receive advice from different sources including human experts and statistical methods. This research examines, in the context of stock price forecasting, how the apparent source of the advice affects the attention that is paid to it when the mode of delivery of the advice is identical for both sources. In Study 1, two groups of participants were given the same advised point and interval forecasts. One group was told that these were the advice of a human expert and the other that they were generated by a statistical forecasting method. The participants were then asked to adjust forecasts they had previously made in light of this advice. While in both cases the advice led to improved point forecast accuracy and better calibration of the prediction intervals, the advice which apparently emanated from a statistical method was discounted much more severely. In Study 2, participants were provided with advice from two sources. When the participants were told that both sources were either human experts or both were statistical methods, the apparent statistical‐based advice had the same influence on the adjusted estimates as the advice that appeared to come from a human expert. However when the apparent sources of advice were different, much greater attention was paid to the advice that apparently came from a human expert. Theories of advice utilization are used to identify why the advice of a human expert is likely to be preferred to advice from a statistical method. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献
