The purpose of this article is to analyse ethnoracial differences in income attainment, as well as differences in earnings that can be attributed to social capital. The data set is the Ethnic Diversity Survey, a large survey of Canadians conducted by Statistics Canada in 2002. Bivariate and multivariate analyses show that ethnoracial minorities are disadvantaged when compared with the British or whites in general. This disparity remains even after controlling for a host of theoretically relevant variables. The brunt of this disadvantage is experienced by male visible-minority immigrants. Although social capital is shown to exert an independent effect on earnings, its benefit varies by social origins, types of social capital, birth, and gender. Trust is important for females’ earnings but not for males’. Family contact and religious participation benefits British males’ earnings more than those of visible-minority males. Religious participation also benefits those born in Canada more than those who immigrated to Canada. In contrast, female immigrants benefit from their associational participation more than females born in Canada. 相似文献

Most of research on fostering ethical behavior among students has taken place in US and Europe. This paper seeks to provide
additional information to both educators and organizations about the ethical perceptions of Iranian students by investigating
the effect of gender on students’ ethical behavior. The authors developed and administered a quantitative questionnaire to
a sample of 203 individuals currently pursuing accredited degrees at one of the public universities in Iran. Statistical analysis
revealed that male students have a significantly less ethical behavior in three factors (selfishness, academic cheating and
computer ethics) than female students. While the topic of students’ ethical behavior and its relationship with gender has
been extensively studied before, there have been contrasting findings by different researchers. This paper is among the very
few first researches conducted among Iranian university students to investigate the effects of gender on students’ ethical
behavior under the four categories of violation of school regulations, selfishness, academic cheating, and computer ethics,
hence making an important contribution to the ethics literature on the developing countries, since the study was conducted
in Iran. 相似文献

The present study examined the influences of marital status on different episodic and semantic memory tasks. A total of 1882 adult men and women participated in a longitudinal project (Betula) on memory, health and aging. The participants were grouped into two age cohorts, 35-60 and 65-85, and studied over a period of 5 years. Episodic memory tasks concerned recognition and recall, whereas semantic memory tasks concerned knowledge and fluency. The results showed, after controlling for education, some diseases, chronological age and leisure activity as covariates, that there were significant differences between married and single individuals in episodic memory, but not in semantic memory. Married people showed significantly better memory performances than singles in both subsystems of episodic memory, that is, recall and recognition. Also, the rate of decline in episodic memory was significantly larger for singles and widowed than other groups over the 5-year time period in both age groups. The findings demonstrate that the positive relation found between marriage and health can be extended to the relation between marriage and cognitive performance. This effect might be explained by the role played by cognitive stimulation in memory and cognition. 相似文献

This study investigated the novel associations between intrinsic and extrinsic aspirations and internal and external domains of contingent self-worth among a sample of 502 Iranian university students. We found a meaningful pattern showing that intrinsic aspirations were positively associated with internal domains, whereas extrinsic aspirations were positively associated with external domains. Our survey data also suggested that the factor structure of the Aspiration Index, as well as the factor structure of the Contingencies of Self-Worth Scale in our Iranian sample were consistent with factor structures of foreign samples. Finally, the types of aspirations and domains of contingencies of self-worth meaningfully predicted variables related to well-being, confirming previous research. We discuss the nature of the associations between the aspirations and the domains of contingent self-worth. 相似文献

In this article, we argue that although Bohr's version of the Copenhagen interpretation is in line with several key elements of logical positivism, pragmatism is the closest approximation to a classification of the Copenhagen interpretation, whether or not pragmatists directly influenced the key figures of the interpretation. Pragmatism already encompasses important elements of operationalism and logical positivism, especially the liberalized Carnapian reading of logical positivism. We suggest that some elements of the Copenhagen interpretation, which are in line with logical positivism, are also supported by pragmatism. Some of these elements are empirical realism, fallibilism, holism, and instrumentalism. However, pragmatism goes beyond logical positivism in espousing some other key elements of the Copenhagen interpretation, though imperfectly, such as the correspondence principle, complementarity, and indeterminism. 相似文献

Scientific study of dreams requires the most objective methods to reliably analyze dream content. In this context, artificial intelligence should prove useful for an automatic and non subjective scoring technique. Past research has utilized word search and emotional affiliation methods, to model and automatically match human judges’ scoring of dream report’s negative emotional tone. The current study added word associations to improve the model’s accuracy. Word associations were established using words’ frequency of co-occurrence with their defining words as found in a dictionary and an encyclopedia. It was hypothesized that this addition would facilitate the machine learning model and improve its predictability beyond those of previous models. With a sample of 458 dreams, this model demonstrated an improvement in accuracy from 59% to 63% (kappa = .485) on the negative emotional tone scale, and for the first time reached an accuracy of 77% (kappa = .520) on the positive scale. 相似文献

In the present study, we investigated the influence of bilateral intra-central amygdala (intra-CeA) microinjections of N-methyl-d-aspartate (NMDA) receptor agents on amnesia induced by a cannabinoid CB1 receptor agonist, arachydonilcyclopropylamide (ACPA). This study used a step-through inhibitory (passive) avoidance task to assess memory in adult male Wistar rats. The results showed that intra-CeA administration of ACPA (2 ng/rat) immediately after training decreased inhibitory avoidance (IA) memory consolidation as evidenced by a decrease in step-through latency on the test day, which was suggestive of drug-induced amnesia. Post-training intra-CeA microinjections of NMDA (0.0001, 0.001 and 0.01 μg/rat) did not affect IA memory consolidation. However co-administration of NMDA with ACPA (2 ng/rat) prevented the impairment of IA memory consolidation that was induced by ACPA. Although post-training intra-CeA administration of the NMDA receptor antagonist, d-(−)-2-amino-5-phosphonopentanoic acid (d-AP5; 0.01, 0.05 and 0.1 μg/rat) alone had no effect, its co-administration with an ineffective dose of ACPA (1 ng/rat) impaired IA memory consolidation. Post-training intra-CeA microinjection of an ineffective dose of d-AP5 (0.01 μg/rat) prevented an NMDA response to the impaired effect of ACPA. These results suggest that amnesia induced by intra-CeA administration of ACPA is at least partly mediated through an NMDA receptor mechanism in the Ce-A. 相似文献
