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

The discussion of universities anddemocracy has conventionally dealt first andforemost with the curriculum, or with thespirit of openness and tolerance whichcharacterises the scientific inquiry. In thisarticle I have added a discussion of thesituatedness of knowledge and knowledgeproduction, and, consequently, a discussion ofthe situated character of other roles of theuniversity, including the democratic role. Inthe light of the regress of political partiesand traditional popular movements – phenomenawhich seem to be true both as regardsmembership numbers and as regards level ofactivity – the role as a locally andregionally situated meeting place for avitalisation and defence of democracy seems apromising one for the contemporary university.The article has also emphasised the linksbetween culture, social capital (``the socialfabric') in the surrounding society, and theeconomic growth and welfare of the city andregion. With concepts such as Bildung (oreducation), civic competence (or civility), andculture, and I have tried to draw our attentionto the actual ``places of knowledge,' whoseimportance will certainly grow in the years tocome. The care, the cultivation, and thequalification of these places into supportinginfrastructures for cultural life, creativity,industry, and democracy should be seen as acoherent, holistic mission. It needsrecognition, and articulation, by all those whoare interested in the university as asignificant social factor: politicians,industry, the cultural sector, localcommunities, and, obviously, the academiccommunity itself. 相似文献

We examined recollective experience in odor memory as a function of age, intention to learn, and familiarity. Young and older adults studied a set of familiar and unfamiliar odors with incidental or intentional encoding instructions. At recognition, participants indicated whether their response was based on explicit recollection (remembering), a feeling of familiarity (knowing), or guessing. The results indicated no age-related differences in the distribution of experiential responses for unfamiliar odors. By contrast, for familiar odors the young demonstrated more explicit recollection than the older adults, who produced more know and guess responses. Intention to learn was unrelated to recollective experience. In addition, the observed age differences in remember responses for familiar odors were eliminated when odor naming was statistically controlled. This suggests that age-related deficits in activating specific odor knowledge (i.e., odor names) play an important role for age differences in recollective experience of olfactory information. 相似文献
