Threat relates to right‐wing ideological attitudes at the individual level. The present study aims to extend this relationship to the national level. More specifically, in a sample of 91 nations, we collected country‐level indicators of threat (including inflation, unemployment, gross national product, homicide rate, and life expectancy). Moreover, we analyzed data from the European and World Value Survey (total N = 134,516) to obtain aggregated country‐level indicators for social‐cultural and economic‐hierarchical right‐wing attitudes for each of these countries. In accordance with previous findings based on the individual level, a positive relationship between threat indicators and right‐wing attitudes emerged. This relationship was stronger than what was usually reported at the individual level. In the discussion, we focus on the mutually reinforcing influence at the individual and national levels in terms of right‐wing attitudes. 相似文献

Abstract Urinary incontinence is a common problem in psychiatric settings, particularly among psychogeriatric patients. In view of the known diuretic action of caffeine, the present study assessed the effect of tea and coffee consumption on level of incontinence in selected psychogeriatric inpatients. A total of 14 patients participated in the study which employed a combined “withdrawal” and “multiple-baseline across subjects” design to examine the effect of alternating phases of caffeine exposure and abstinence on frequency of daytime and nighttime incontinence. Incontinence levels were significantly reduced during periods of caffeine abstinence relative to periods of chronic caffeine exposure. The hypothesis that observed reductions in incontinence may have been due to accompanying reductions in fluid intake was examined but not supported. 相似文献

Abstract In order to identify relevant determinants of organ donor registration among Dutch adolescents, a school-based cross-sectional survey was conducted among 145 high school students. Fifty-one percent of respondents indicated they were willing to register as organ donors and 80% reported a positive general attitude towards registration. Various misconceptions about the registration and donation procedure were identified. On average only moderate knowledge levels related to organ donation were found. In order of strongest association, negative outcome expectancies, past behaviour and experience, positive outcome expectancies, and social outcome expectancies proved to be significant predictors of willingness to register as organ donors. Self-efficacy was indirectly associated with willingness via outcome expectancies. Knowledge about organ donation was not significantly associated with willingness. The results suggest that in order to persuade adolescents to register as organ donors, refutational messages will have to be developed to counterargue the prevailing negative outcome expectancies related to organ donation and registration as an organ donor. 相似文献

Evidence from a number of investigations suggests a considerable overlap between reading disability (RD) and attention deficit-hyperactivity disorder (ADHD). We investigate the relationship between RD and ADHD in a cohort of 186 children 7.5–9.5 years of age, recruited explicitly to address classification and definitional issues in these disorders. Using multivariate methods, we examine the hypothesis that RD and ADHD represent separate diagnostic entities that frequently co-occur in the same individual. The results suggest that RD is characterized by deficits within the language system, in particular a subcomponent within that system, phonological processing; in contrast, such linguistic deficits are not characteristic of ADHD unless ADHD is associated with RD. When children with both RD and ADHD are examined, both the linguistic deficits associated with RD and the behavioral characteristics associated with ADHD are apparent, but these deficits are not synergistic. We conclude that RD and ADHD represent separate disorders that frequently co-occur. 相似文献

Previous studies among the four largest immigrant groups in the Netherlands suggest that higher-educated immigrants, who are more apt to integrate, actually experience more discrimination than lower-educated immigrants, which is referred to as the integration paradox. In this study, we first investigate whether this paradox also exists among smaller immigrant groups (i.e. Afghani, Iraqi, Irani, Somali, Polish and Chinese) in the Netherlands. Second, we aim to explain the educational effect on perceived personal discrimination. We derive hypotheses from a theory of exposure and a theory of rising expectations. Data are drawn from a large-scale survey (SING2009) and include close to 1,000 face-to-face interviews for each of the small ethnic minority groups. Our study supports the existence of an integration paradox for small immigrant groups in the Netherlands. Our results show that higher-educated immigrants perceive more personal discrimination, which can be attributed to their exposure to Dutch politics, their experience of relative deprivation regarding their work and education and their participation in associations. 相似文献

Referral of patients with endometrial (EC) and/or ovarian cancer (OC) for genetic counseling is based on age at diagnosis and family history. Many patients with hereditary cancers are missed by following this strategy. We determined acceptance and mutation detection rate of offering genetic counseling and testing to unselected EC and OC patients. Therefore, in 2007, EC and OC patients were invited for genetic counseling and testing. Patients were asked for their reasons to accept or decline. Nineteen out of fifty-two EC patients (36 %) and twenty-two out of thirty-five OC patients (63 %) accepted genetic counseling, mainly to receive risk assessment for themselves and relatives. Counseling was declined mainly because patients did not want more tests or had no relatives for whom it was relevant. Eighteen out of nineteen EC patients (95 %) and twenty out of twenty-two OC patients (91 %) underwent genetic testing. One EC patient carried an MSH6 mutation (mutation detection rate: 6 %). BRCA1/2 mutations were found in two out of twenty OC patients (10 %). Eleven patients (29 %) received surveillance recommendations for themselves and their relatives. Finally, family history recorded by the gynecologist was compared to that taken by the clinical geneticist. Gynecologists reported family history in ten out of forty-one participants (24 %). In conclusion, genetic counseling and testing are acceptable to patients with OC and/or EC. The 10 % BRCA1/2 mutation detection rate and underreporting of family history by gynecologists warrant referral for genetic counseling for all OC patients, followed by BRCA1/2 testing if indicated. We recommend that microsatellite instability and immunohistochemical analysis be performed in all EC patients, followed by genetic counseling if appropriate. These strategies will lead to better cancer prevention in gynecological cancer patients and their relatives. 相似文献

Increasing evidence suggests that people may cognitively represent themselves and others just like any other, nonsocial event. Here, we provide evidence that the degree of self–other integration (as reflected by the joint Simon effect; JSE) is systematically affected by the control characteristics of temporally overlapping but unrelated and nonsocial creativity tasks. In particular, the JSE was found to be larger in the context of a divergent-thinking task (alternate uses task) than in the context of a convergent-thinking task (remote association task). This suggests that self–other integration and action corepresentation are controlled by domain-general cognitive-control parameters that regulate the integrativeness (strong vs. weak top-down control and a resulting narrow vs. broad attentional focus) of information processing irrespective of its social implications. 相似文献

Abstract The attention paid to problems related to mental health of employees in organizations is growing. Although the stress literature is huge and varied, most of the empirical studies are done in traditional work environments in which information technology and computers are of little importance. The recent increasing use of information technology has created a growing number of information processing work environments. The work in those work environments is typically done with data and can be characterized as “mental” work. The general hypothesis in this paper is that people doing mental work relate the perception of their work to mental health. More specifically, this paper describes the relationship between work-related factors and mental health among employees in a typical information processing environment: an insurance company. First, we discuss the concept of mental health. Next, we summarize the results of a number of studies on the determinants of mental health in information work. The results of our study indicate that work and health perception has a greater impact on mental health than work characteristics, personality, and activities outside work. Work perception, health perception, and mental health can be considered as one factor, although there are minor differences between subgroups in the population. In the discussion we try to integrate the findings into a general model of mental health related to work. 相似文献
