In ferromagnets with a non-uniform magnetocrystalline and/or magnetoelastic anisotropy, such as nanocrystalline or cold-worked polycrystalline materials, the static magnetic microstructure gives rise to elastic magnetic small-angle neutron scattering (SANS). The paper explores a method for determining the exchange-stiffness constant A by analysis of the dependence of the elastic SANS cross-section on the applied magnetic field. Experimental results for A and for the spin-wave stiffness constant D in cold-worked or nanocrystalline Ni and Co are found to agree with literature data obtained by inelastic neutron scattering on single-crystal specimens.  相似文献

Within Australia, divisive debates regarding the processing of asylum seekers have delivered increasing polarisation rather than convergence on an evidence‐based, humane approach. In order to investigate the role of motivated reasoning (the idea that our judgment is based on our motivations) with respect to attributions of warmth and competence, 186 participants indicated the extent to which they accepted false beliefs regarding asylum seekers. They read an article rebutting such false beliefs and then reported their attitudes towards the author and the extent to which the author possessed warmth and competence traits. They then reported whether they agreed with the information in the article before completing a test of recall. Participants who disagreed with the article recalled less accurate information and rated authors significantly lower on warmth and competence. These findings suggest that motivated reasoning plays an important role in the way stereotypes are applied and in the way information is processed.  相似文献

The aim of this study was to test the hypothesis that male assistant nurses, representing a small gender minority in their profession and in the work organizations they inhabit, are more often exposed to bullying at work than their female colleagues. In 1999, a random sample of the assistant nurses organized in the Norwegian Union of Health and Social Workers were mailed a questionnaire; 7478 out of 12,000 (62.3%) completed the questionnaire. The sample of the present study comprised the 6485 respondents who were vocationally active and not on leave. 3.8% (n?=?247) of the respondents were men; 10.2% (n?=?25) of the men and 4.3% (n?=?265) of the women reported that they had been exposed to bullying at work during the previous 6 months, χ2?=?19.12, df?=?1, p?<?.0001. The association between gender and exposure to bullying at work remained strong and significant (odds ratio?=?2.29; 95% confidence interval?=?1.39?-?3.78; p?=?.001) even after adjustment for a series of background factors. The study supports the hypothesis that male assistant nurses are more often exposed to bullying at work than their female colleagues.  相似文献

We examined the relationship between type 2 diabetes mellitus and cognitive function in a population-based sample of very old people. The sample comprised 338 persons, aged 80-93 years (mean age 83.5 years), of whom 70 persons had type 2 diabetes mellitus. Measures of cognitive functioning included tests of perceptual speed, visuo-spatial ability, inductive reasoning, short-term memory, semantic memory, episodic memory, and the Mini-Mental State Examination. Regression analyses showed that type 2 diabetes mellitus duration was related to test performance across all cognitive domains, with the exception of short-term memory, such that longer duration was associated with lower test performance. When cases with dementia were excluded from the sample, further analyses showed that diabetes duration was not associated with cognitive test performance. This indicates that diabetes is not related to lower cognitive function in the general population of non-demented old people. Diabetes, however, increases the risk for cerebrovascular incidents, like stroke, that may contribute to vascular dementia.  相似文献

Intelligence/personality associations were studied in four large datasets. Correlations between general ability (g) and major personality traits were generally consistent with previous findings. For other traits, an interpretation of the correlation patterning is that traits classifiable as adaptive in terms of personal and social adjustment have positive correlations with g, whilst maladaptive traits have negative correlations. Regression modelling confirmed these associations and structural equation modelling of selected traits showed that Neuroticism acts as a mediator of g on the outcome. Non-linear relationships between intelligence and personality were not found. In two of the datasets the correlation between Neuroticism and Psychoticism decreased with ability level, and the correlation between fluid and crystallised ability increased with level of Neuroticism.  相似文献

Since the demise of the Association for Intercollegiate Athletics for Women (AIAW), female sport administrators have continued their struggle to reestablish their place as athletic directors. The purpose of this study was to assess the rate of advancement (success ratio) of intercollegiate athletic directors, with a primary focus on gender. Athletic directors from 157 NCAA (National Collegiate Athletics Association) member institutions participated in the study. The preliminary results confirmed the expected findings that hegemonic masculinity was entrenched within intercollegiate athletics. The success ratio of male athletic directors differed from that of female athletic directors, and the difference was significant (p ≤ .05). The success ratio for men was higher than the ratio for women. Further analyses, however, showed that female athletic directors had higher success ratios than their male peers at lower level institutions. Although parity in numbers has not yet been achieved across the NCAA, the glass ceiling at Division I institutions may begin to crack as more women achieve success at the lower level institutions.  相似文献

Changes in the contemporary labour market have resulted in an increasing demand for flexibility in the work context. The present research examines the associations between unemployed individuals' work values and their attitudes towards job flexibility. Consistent with Expectancy‐Value Theory, results showed that the general concept of employment value was positively related to all measured types of flexibility, that is, training flexibility, pay flexibility, the flexibility to accept an undemanding job, and the flexibility to accept a job for which one is over‐qualified. In line with Self‐Determination Theory, holding an intrinsic work value orientation related positively to training and pay flexibility, whereas extrinsic work value orientation was negatively related to these two types of flexibility. Overall, these results indicate that not only the degree of employment value but also the content of unemployed individuals' work value orientations matter in understanding their job flexibility. L'évolution actuelle du marché de l'emploi a provoqué une demande croissante de flexibilité dans le domaine du travail. On étudie dans cette recherche les liens qui existent entre les valeurs professionnelles de chômeurs et leurs attitudes envers la flexibilité. Dans la ligne de la théorie expectation‐valence, les résultats montrent que le concept général de valence de l'emploi est relié positivement à toutes les mesures de la flexibilité, c'est‐à‐dire la flexibilité de la formation, du salaire et de l'acceptation d'un poste sans intérêt ou sous‐qualifié. En accord avec la théorie de l'autodétermination, le fait d'accorder une valeur intrinsèque au travail entretient une corrélation positive avec la flexibilité de la formation et du salaire, tandis que la valeur extrinsèque est en relation négative avec ces deux aspects de la flexibilité. En somme, ces résultats indiquent que chez les chômeurs non seulement le niveau de la valence de l'emploi, mais aussi le contenu des valeurs relatives au travail permettent de comprendre leur flexibilité.  相似文献

This essay discusses three recent books which each offer an integrative account of religious ethics and the environment. Religious environmental ethics is an area of inquiry within the larger field of religion and ecology. After a narrative that contextualizes the development of religious environmental ethics in relation to the environmental social movement, I describe the formation of the field including its focus on worldview, the “cosmological turn,” and its engagement with science, the “cosmic turn.” Elizabeth Johnson exemplifies the cosmic turn by developing a Christian theology of life in nature which explicitly accepts Darwin's theory of evolution. Willis Jenkins advocates a prophetic pragmatism and critiques a focus on worldview that is abstracted from practice and defers moral responsibility. Larry Rasmussen joins analysis of worldview with reflection on cross‐cultural resources for “anticipatory communities” of moral formation to catalyze change. I argue with Rasmussen that religious environmental ethics needs multiple approaches and should allow room for methodological pluralism.  相似文献
