This study examines whether Big Five personality traits affect the extent to which a socially anxious child will be victimized. A total of 1814 children participated in the study (mean age = 11.99 years). Children completed self‐reports and peer reports of victimization, which were aggregated, and self‐reports of social anxiety and Big Five personality traits. A regression analysis was performed to study the moderating effect of personality traits on the relation between social anxiety and victimization. Socially anxious children scoring high on extraversion are less at risk for victimization than socially anxious children scoring low on extraversion. In addition, socially anxious boys scoring high on agreeableness were less at risk for victimization than socially anxious boys scoring low on agreeableness. Conscientiousness, neuroticism, and openness to experience did not moderate the relation between social anxiety and victimization. 相似文献

A prevalence of heavy-tailed, peaked and skewed uncertainty phenomena have been cited in literature dealing with economic,
physics, and engineering data. This fact has invigorated the search for continuous distributions of this nature. In this paper
we shall generalize the two-sided framework presented in Kotz and van Dorp (Beyond beta: other continuous families of distributions
with bounded support and applications. World Scientific Press, Singapore, 2004) for the construction of families of distributions with bounded support via a mixture technique utilizing two generating
densities instead of one. The family of Elevated Two-Sided Power (ETSP) distributions is studied as an instance of this generalized
framework. Through a moment ratio diagram comparison, we demonstrate that the ETSP family allows for a remarkable flexibility
when modeling heavy-tailed and peaked, but skewed, uncertainty phenomena. We shall demonstrate its applicability via an illustrative
example utilizing 2008 US income data. 相似文献

National identity, macro and micro economic expectations affect the attitude toward the euro. In a study in The Netherlands, data were collected and relationships between the latent concepts were modelled with LISREL. In the best fitting model, national identity has a direct and an indirect effect on attitude, respectively, an unstructured and a structured effect. The indirect effect is mediated by macro and micro expectations. Macro expectations also have a direct and an indirect effect. The indirect effect is mediated by micro expectations. On one hand, macro expectations form a strong link between national identity and attitude. On the other hand, macro expectations have a strong direct effect on attitudes. The euro is mainly perceived and evaluated in a macro-economic perspective.PsycINFO classification: 2229; 3920 相似文献

Public relations is often studied from a managerial, instrumental perspective or a psychological, behavioral perspective. To understand the role of public relations in building trust or mistrust and to develop – or destroy – a license to operate, it needs also to be studied as a social phenomenon. 相似文献

We derive an identity for nonparametric maximum likelihood estimators (NPMLE) and regularized MLEs in censored data models
which expresses the standardized maximum likelihood estimator in terms of the standardized empirical process. This identity
provides an effective starting point in proving both consistency and efficiency of NPMLE and regularized MLE. The identity
and corresponding method for proving efficiency is illustrated for the NPMLE in the univariate right-censored data model,
the regularized MLE in the current status data model and for an implicit NPMLE based on a mixture of right-censored and current
status data. Furthermore, a general algorithm for estimation of the limiting variance of the NPMLE is provided.

Children's tattling on their siblings was observed in 39 families when children were 2- and 4- and 4- and 6-years of age. Tattling was more frequent among older siblings, and increased across time, despite a corresponding decrease in sibling transgressions against one another and an increase in parents' negative reactions to tattling. Tattling was largely truthful, implicit in form, and more likely to concern transgressions of what parents also regarded as more important standards. Among 4- and 6-year-olds, tattling was related to children's negative behaviour to one another and equally likely when children faced ongoing conflict issues and when they merely wished to inform parents of sibling wrongdoing. Parents generally allowed their children to tattle on one another, rarely reprimanded tattlers, but responded to the information contained in the tattlers' reports. The parents' responses were related to the quality of their children's tattling, but the children's tattling was unrelated to the likelihood that parents would react either positively or negatively to it. Results are discussed in terms of the place of tattling within the family system, with emphasis on the children's understanding of the implications of their parents' involvement in their own disputes. 相似文献

Five years of the annual Health Interview Survey, conducted by the National Center for Health Statistics, are used to estimate the effects of air pollution, smoking, and environmental tobacco smoke on respiratory restrictions in activity for adults, and bed disability for children. After adjusting for several socioeconomic factors, the multiple regression estimates indicate that an independent and statistically significant association exists between these three forms of air pollution and respiratory morbidity. The comparative risks of these exposures are computed and the plausibility of the relative risks is examined by comparing the equivalent doses with actual measurements of exposure taken in the homes of smokers. The results indicate that: (1) smokers will have a 55-75% excess in days with respiratory conditions severe enough to cause reductions in normal activity; (2) a 1 microgram increase in fine particulate matter air pollution is associated with a 3% excess in acute respiratory disease; and (3) a pack-a-day smoker will increase respiratory restricted days for a nonsmoking spouse by 20% and increase the number of bed disability days for young children living in the household by 20%. The results also indicate that the estimates of the effects of secondhand smoking on children are improved when the mother's work status is known and incorporated into the exposure estimate. 相似文献

Effect of Sociocultural Context and Parenting Style on Scholastic Achievement among Iranian Adolescents 总被引:1,自引:0,他引:1

School grades, family demographics and responses to the parental authority questionnaire were assessed in 240 eighth‐grade students in the southern, central and northern parts of Tehran, Iran's capital. The result showed that poorer families with traditional values had more authoritarian attitudes toward parenting than richer families with more modern values. In contrast to the studies conducted in East Asian societies, the current study found that authoritative parenting was the style associated with the highest academic outcome. Tests of mediation and moderation effects showed that the relation between parenting style and academic outcome was independent of sociocultural context. 相似文献
