The strain-hardening behaviour of metals and alloys are significantly affected by the dynamic recovery process, the rate of which can be increased by increases in deformation temperature and/or stacking fault energy (SFE). In the present work, the decay slope of the strain-hardening rate with flow stress as a function of both temperature and stacking fault energy is quantitatively evaluated for several face-centered cubic metals and alloys. A universal and quantitative approach to the scaling of the effects of temperature and stacking fault energy on strain-hardening behaviour is developed, which could be useful for predicting deformation behaviour or for material design.  相似文献

The use of a visual analogue scale (VAS) for the assessment of stress during occupational health examination could be an useful tool. However, psychometrics features of the VAS have to be assessed. The aim of this study is to test the inter judge reliability of the VAS in a psychological dimension assessment. Two occupational physician have used the VAS in a worker group. There is no significant difference in the distribution of VAS values. This result supports the hypothesis of a satisfactory inter judge reliability of the VAS in stress measurement.  相似文献

When trauma enters into the reality of the analyst and of the analysand, when it attacks the setting, what becomes of the analyst’s role? How can transformations be brought about? With reference to three clinical situations, the author attempts to explore how the articulation between transference and countertransference – the inter‐relation – structures the situation; the analyst must remain in his or her role as analyst through managing to create and to reflect upon the clinical aspects of that situation when faced with the unpredictability of what war brings in its wake. It then becomes possible to see how the work of the negative can be confined to the outer limits of the setting.  相似文献

The unit-decade compatibility effect is interpreted to reflect processes of place value integration in two-digit number magnitude comparisons. The current study aimed at elucidating the influence of language properties on the compatibility effect of Arabic two-digit numbers in Austrian, Italian, and Czech first graders. The number word systems of the three countries differ with respect to their correspondence between name and place value systems; the German language is characterized by its inversion of the order of tens and units in number words as compared with digital notations, whereas Italian number words are generally not inverted and there are both forms for Czech number words. Interestingly, the German-speaking children showed the most pronounced compatibility effect with respect to both accuracy and speed. We interpret our results as evidence for a detrimental influence of an intransparent number word system place value processing. The data corroborate a weak Whorfian hypothesis in children, with even nonverbal Arabic number processing seeming to be influenced by linguistic properties in children.  相似文献

新近出现的绩效结构理论认为员工绩效包括角色内行为、组织公民行为和工作越轨行为三种类型。然而在后两种行为的关系上,当前研究者还未达成一致意见。文章综合采用三种方式证实了组织公民行为和工作越轨行为是两种完全不同的行为类型,而不是一种行为的两种性质不同的表现,从而为三维绩效模型的合理性提供了间接支持。在此基础上,研究还证实了工作越轨行为中两种成分(组织越轨和人际越轨)的不同。文章最后对研究结果进行了讨论,并指出了未来研究方向。  相似文献

This research reports about asymmetrical relations in self-other ratings of attachment style. Specifically, results showed that romantic partners hold relatively accurate perceptions of each other’s attachment styles with one exception: women’s ability to judge their male partner’s level of attachment-related anxiety was compromised compared with the other agreement indices measured. The effect was not moderated by acquaintanceship length or relationship satisfaction, but it was affected by men’s interpersonally oriented self-control. The findings appear to reflect men’s reluctance from appearing anxious to their female partners and from the nature of the anxiety dimension of attachment. Anxiety (as compared with avoidance) has a less consistent interpersonal behavioral manifestation and thus is more concealable among those motivated and capable of doing so.  相似文献

Recent ERP findings challenge the widespread assumption that syntactic and semantic processes are tightly coupled. Syntactically well-formed sentences that are semantically anomalous due to thematic mismatches elicit a P600, the component standardly associated with syntactic anomaly. This ‘thematic P600’ effect has been attributed to detection of semantically plausible thematic relations that conflict with the surface syntactic structure of the sentence, implying a processing architecture with an independent semantic analyzer. A key finding is that the P600 is selectively sensitive to the presence of plausible verb-argument relations, and that otherwise an N400 is elicited (The hearty meal was devouring … vs. The dusty tabletop was devouring …: Kim & Osterhout, 2005). The current study investigates in Spanish whether the evidence for an independent semantic analyzer is better explained by a standard architecture that rapidly integrates multiple sources of lexical, syntactic, and semantic information. The study manipulated the presence of plausible thematic relations, and varied the choice of auxiliary between passive-biased fue and active-progressive biased estaba. Results show a late positivity that appeared as soon as comprehenders detected an improbable combination of subject animacy, auxiliary bias, or verb voice morphology. This effect appeared at the lexical verb in the fue conditions and at the auxiliary in the estaba conditions. The late positivity elicited by surface thematic anomalies was the same, regardless of the presence of a plausible non-surface interpretation, and no N400 effects were elicited. These findings do not implicate an independent semantic analyzer, and are compatible with standard language processing architectures.  相似文献

Work–family conflict and enrichment are experiences that occur daily and have substantial consequences for employees, their families, and the organizations that employ them. The aim of the current review is to make a link between life and career stage, work and family conditions, and the work–family interface. The basic proposition is that life stages partly determine career development, and consequently the specific working conditions (job demands and job resources) and family conditions (family demands and family resources) that individuals are exposed to. As a result, the specific demands and resources in the work and family domains determine to what extent individuals experience that work and family are conflicting or enriching life domains. In this review we suggest that individuals in early adulthood will experience high inter‐role conflict and low facilitation due to high demands and low resources in both life domains, while individuals in late adulthood will experience the opposite pattern; that is, low conflict and high facilitation due to low demands and high resources in both domains. Individuals in middle adulthood will experience high work–family conflict but also high family–work facilitation due to the presence of high job demands and resources in both life domains. Integrating life and career stage perspectives and the experience of work–family interface is of notable practical utility because it provides a mechanism to make more informed decisions about the relative need for and corresponding benefits of work–family programs.  相似文献

Self‐serving biases in attribution, while found with relative consistency in research with Western samples, have rarely been found in Japanese samples typically recruited for research. However, research conducted with Japanese participants to date has tended to use forced‐choice and/or reactive paradigms, with school or university students, focusing mainly on academic performance or arbitrary and/or researcher‐selected tasks. This archival study explored whether self‐serving attributional biases would be shown in the real‐life attributions for sporting performance made by elite Olympic athletes from Japan and Australia. Attributions (N = 216) were extracted from the sports pages of Japanese and Australian newspapers and rated by Australian judges for locus and controllability. It was hypothesized that Australian, but not Japanese, athletes would show self‐serving biases such that they attributed wins to causes more internal and controllable than the causes to which they attributed losses. Contrary to predictions, self‐serving biases were shown to at least some extent by athletes of both nationalities. Both Australian and Japanese men attributed wins to causes more internal than those to which they attributed losses. Women, however, attributed wins and losses to causes that did not differ significantly in terms of locus. All athletes tended to attribute wins to causes that were more controllable than the causes to which losses were attributed. Results are inconsistent with a large body of research suggesting that Japanese do not show self‐serving biases in attribution, and are discussed in the light of differences in methodology, context, and participants that may have contributed to these effects.  相似文献

For many years, it has been suggested that drugs that interfere with dopamine (DA) transmission alter the "rewarding" impact of primary reinforcers such as food. Research and theory related to the functions of mesolimbic DA are undergoing a substantial conceptual restructuring, with the traditional emphasis on hedonia and primary reward yielding to other concepts and lines of inquiry. The present review is focused upon the involvement of nucleus accumbens DA in effort-related choice behavior. Viewed from the framework of behavioral economics, the effects of accumbens DA depletions and antagonism on food-reinforced behavior are highly dependent upon the work requirements of the instrumental task, and DA-depleted rats show a heightened sensitivity to response costs, especially ratio requirements. Moreover, interference with accumbens DA transmission exerts a powerful influence over effort-related choice behavior. Rats with accumbens DA depletions or antagonism reallocate their instrumental behavior away from food-reinforced tasks that have high response requirements, and show increased selection of low reinforcement/low cost options. Nucleus accumbens DA and adenosine interact in the regulation of effort-related functions, and other brain structures (anterior cingulate cortex, amygdala, ventral pallidum) also are involved. Studies of the brain systems regulating effort-based processes may have implications for understanding drug abuse, as well as symptoms such as psychomotor slowing, fatigue or anergia in depression and other neurological disorders.  相似文献
