Are risk preferences stable? Comparing an experimental measure with a validated survey-based measure 总被引:2,自引:0,他引:2
We examine the stability of risk preference within subjects by comparing measures obtained from two elicitation methods, an
economics experiment with real monetary rewards and a survey with questions on hypothetical gambles. The survey questions
have been validated by numerous empirical studies of investment, insurance demand, smoking and alcohol use, and recent studies
have shown the experimental measure is associated with several real-world risky behaviors. For the majority of subjects, we
find that risk preferences are not stable across elicitation methods. In interval regression models subjects’ risk preference
classifications from survey questions on job-based gambles are not associated with risk preference estimates from the experiment.
However, we find that risk classifications from inheritance-based gambles are significantly associated with the experimental
measure. We identify some subjects for whom risk preference estimates are more strongly correlated across elicitation methods,
suggesting that unobserved subject traits like comprehension or effort influence risk preference stability. 相似文献

Determining the distribution of psychiatric disorders and developing sound preventive and intervention practices are pressing public health issues. Since at present mental disorders lack biological markers, psychiatric taxonomies must grapple with how best to address issues of validity and reliability. With the increasing congruence between the International Classification of Diseases (ICD-11) and the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) (American Psychiatric Association, 2010), it is imperative that decisions regarding the inclusion of new disorders be research-based and not unduly influenced by industry. The first draft of DSM-V, recently made public, has created a firestorm of controversy, for the DSM's nomenclature of disease or other pathology not only affects such disparate domains as jurisprudence and insurance claims but is also an instrument designed to facilitate research on psychopathology. 相似文献

From the mid 1980s onwards HIV/AIDS became a new subject of work reform, with a range of experts producing new knowledges on work and the worker in regard to HIV/AIDS and workplace organizations putting in place workplace HIV/AIDS policies and programmes. To date, much of the discussion in sociology in regard to such policies and programmes has focused on the issue of effectiveness and has been concerned with making such policy 'better'. In this article however, and with particular reference to sexuality, I suggest that such approaches fail to register that workplace HIV/AIDS policies concern new conceptualizations of worker identities. Specifically, I suggest that such policies may be viewed as part of an assemblage of work reforms which are reworking worker identities as risk identities. Thus I argue that workplace HIV/AIDS policies and programmes are best understood as risk rationalities. Further, I consider the alignment between such rationalities and neo-liberal modes of rule, and in particular consider the ways in which workplace HIV/AIDS policies render both HIV/AIDS and sexuality calculable and governable in terms of notions of risk, self-responsibility and self-management. 相似文献

Youth conferences can be effective means for engaging youth in the life of their schools, communities, and nation, bringing benefits not only to youth themselves but also to the community, which gains through the energy, ideas, and values that youth contribute. 相似文献

We evaluated the interactive influences of attentional state and attentional inertia on infants' level of attentional engagement. We assessed infants' distraction latencies longitudinally at 6.5 and 9 months as they explored toys, and we coded both their attentional state (focused vs. casual) and how long they had been looking at the toy at each distractor onset. Consistent with previous results, both attentional state and attentional inertia contributed to differences in distraction latency. Importantly, the level of attentional engagement was interactively determined by attentional state and attentional inertia. Infants were most resistant to distraction when they were judged to be in a state of focused attention following relatively long looks to the toy, and they were equivalently less resistant to distraction under all other conditions. These results are consistent with a general conceptualization of attentional engagement resulting from the interaction of multiple processes. 相似文献

A procedure for improving children's skill in decoding facial expressions of emotion was studied in this experiment. In the first phase of the study, thirty-six fifth and sixth grade children watched video segments showing facial expressions of stimulus persons experiencing happiness, sadness, or fear and tried to identify each stimulus person's emotion. Subjects assigned to the feedback condition were given the correct answer for each segment, and subjects assigned to the no feedback condition received no information. Results for the second phase of the experiment, in which subjects' decoding skills were assessed, showed that the feedback method was effective in improving general decoding abilities. Furthermore, differences between subjects in the feedback and no feedback conditions were affected by subjects' sex and the specific emotion being decoded.Portions of this study were presented at the annual meeting of the Eastern Psychological Association, Boston, April, 1989. This study was funded by a grant from the Marks Meadow Research Foundation, as well as through ongoing support from the National Institute of Disability and Rehabilitation Research, U.S. Department of Education, to the second author. 相似文献

Although a number of studies have investigated the consequences of leader-member similarity in the United States, there has been a dearth of research on its effects in other countries. Using a sample of 135 Mexican workers and their managers, this study assessed the effects of leader-member demographic similarity on members' organizational attachment (absence and organizational commitment) in a North Mexican manufacturing facility. Results showed that leader-member gender similarity was negatively associated with absence, and this effect was stronger for dyads with female leaders than for dyads with male leaders. Age similarity had mixed effects on attachment. While it had a negative association with absence (an indicator of lack of attachment), it also had a negative association with organizational commitment (an indicator of attachment). These findings are interpreted in the context of social psychological phenomena and elements of Mexican culture. 相似文献

Task Interdependence as a Moderator of the Relation Between Group Control and Performance 总被引:4,自引:0,他引:4
Data were collected from the managers of 77groups in a large service organization and a largemanufacturing organization. The results revealed thatthe relation between group control over decision making and group performance became more positive withincreased levels of task interdependence. The mainimplication of the findings is that increasing groupcontrol over decisions may result in high performance only for groups that are highly taskinterdependent. The performance of groups that are lowin task interdependence may suffer when provided withgroup-level control of decisions. 相似文献

This study examined the relationship between personal characteristics (gender, acculturation, belief in gender stereotypes, recent dating experiences), and attitudes and knowledge about dating violence in urban Latino youth (N = 678). All participants completed self-administered surveys at school. Relative to girls, boys held more problematic (proviolence) attitudes about dating violence and reported less knowledge about dating violence and its consequences. Teens who were more traditional (less acculturated), those who endorsed gender stereotypes, and those who reported recent fearful dating experiences tended to report less knowledge about abuse and lower endorsement of nonviolent attitudes. Multivariate analyses revealed that all four personal variables predicted dating violence knowledge. By contrast, attitudes were predicted by endorsement of gender stereotypes only, or gender stereotypes and gender. Implications for dating violence interventions and future directions for research are explored. 相似文献
