An k -phase Mn-Al-C single crystal was grown and annealed to obtain an intermediate stage of the k M transformation. The crystal was analysed by transmission electron microscopy, and direct evidence for the operation of the shear mode was obtained. The transformation occurs in two steps from the hcp structure ( k ) over the orthorhombic structure ( k ' phase) to the tetragonal phase. The study reveals the morphologies of k ' and , the necessity for reordering during the second transformation step ( k ' M ) which is not a purely martensitic transformation, and the selection of variants which is controlled by stresses through the selection of one k ' variant. 相似文献

Abstract The local translational order of the icosahedral quasicrystalline phase in rapidly solidified V41Ni36Si23 has been investigated by means of selected-area electron diffraction and high-resolution electron microscopy. Experimental results show that translational order always occurs in the twofold direction and can be observed when the quasicrystal is examined along its fivefold and threefold as well as twofold axes. Sometimes it occurs in two or three coplanar twofold directions simultaneously. In these cases some crystalline islands exist in the icosahedral quasicrystal and this corresponds to the initial stage of transformation from a quasicrystal to the stable crystalline phase. 相似文献

This contribution examines the emotional engagement of men and women when reading narrative texts, aiming to see under which textual conditions men and women turn out to be different from or similar to each other in what they think and feel during reception. As part of an experimental mixed-methods study, male and female readers are asked to read either experience-type texts (focusing on inner experiences of characters) or action-type texts (focusing on actions as part of a suspenseful plot) and report their engagement on questionnaire scales and in written protocols. Results show that men and women differ in their engagement when reading action texts and in their emotional affinity to plots. They are highly similar when reading the experience texts, however, and in their affinity to characters. This study underlines that the emotional responses of males and females during reading are highly dependent on (con)textual cues. 相似文献

Two experiments were conducted among Turkish students to explore the effects of team or personally oriented expressions of pride or shame for joint success or failure on evaluations of the outcome, team, and partner; causal attributions were also explored. In the second experiment, complying with a partner's choice of task and influencing the preference for future partners under high or low pressure were examined. Results indicated that for success outcomes, team expressions (relative to personal ones) caused more favorable evaluations of the outcome, team harmony, and the partner, and more causal attributions to the team as a unit. Nonsignificant but consistent opposite tendencies were observed for failure outcomes. The results of the second experiment further indicated that low pressure was more effective than high in increasing preference for personally oriented partners and was marginally effective in increasing agreement for future tasks under the personal expression condition. 相似文献

In this study, we assessed cross-cultural differences in the extent to which general emotional intelligence is linked to life satisfaction and analyzed mediators of this relationship. We used data from an individualistic culture (Germany) and a collectivistic culture (India) and had university students respond to self-report measures of life satisfaction, positive and negative affect, emotional intelligence, perceived social support, and independent and interdependent self-construals. In line with our hypotheses, we found that Indian students reported less subjective well-being and emotional intelligence than German students. Emotional intelligence was associated with life satisfaction to a higher degree in Germany than in India. In Germany, independent but not interdependent self-construal was related to emotional intelligence; in India, both independent and interdependent self-construals were significantly associated with emotional intelligence. Results of structural equation modeling provided support for our hypotheses regarding mediational models in that the effect of emotional intelligence on life satisfaction was fully mediated by affect balance in Germany and by perceived social support in India. 相似文献

A cross sectional study of 60 student teams examined the impact of team diversity, team interaction processes (planning/organizing) and intrateam conflict on team creativity in a Web site design task. An input–process–output model was used as a theoretical background and it was predicted that team diversity has an indirect impact on team creativity, mediated by planning/organizing and intrateam conflict, as well as a direct impact, with team variety being beneficial for team creativity, and team disparity being detrimental for team creativity. The results support the overall path model and show that the impact of team diversity on team creativity in Web site design is mediated by the team processes and intrateam conflict. 相似文献

This study investigated gender differences in anxiety and coping styles under the stress of intense military training. We surveyed Chinese female (n = 470) and male (n = 379) military officers who were surveyed during the third month of a 10-month intensive training program. Results indicated that state and trait anxiety were highly correlated in both women and men. In general, female officers had higher levels of anxiety, greater negative coping tendencies, and less perceived self-efficacy than their male counterparts. When compared with the norm, both women and men had significantly more positive coping strategies. A hierarchical multiple regression analysis showed factors that influenced male and female state anxiety. Avoidance, which was chosen by women more often than men, in general was less useful for female officers. The most common positive coping style for female officers was problem solving, whereas for men it was help seeking. We suggested that even female officers with lower mental health levels than their male counterparts made active cognitive changes to their coping styles when undergoing intense military training. 相似文献

Discrepancies between one's own beliefs, standards and practices and the standards expected by others are associated with increased vulnerability to depression and anxiety. Perhaps the most important personal standard is morality, one's standard of acceptable behaviour. We therefore reason that perceived discrepancies between one's own moral standards and those of society predict anxious and depressed moods. We tested this hypothesis, for the first time, in a sample of 99 female Turkish students. Moral discrepancies were assessed using an adapted moral foundations scale: participants were asked how much payment they would require to perform a series of potentially immoral acts, and how much payment they thought the average person in society would require. Participants also completed standard questionnaire measures of depression and trait anxiety. Results show that perceived self‐society moral discrepancies were significantly related to depression scores, but not to anxiety scores. Furthermore, only discrepancies related to the moral dimensions of respect for ingroups and avoiding harm were related to depression. We argue that perceiving a discrepancy between one's own standards of behaviour and those of society can increase vulnerability to depression, much as other kinds of self‐other discrepancies can; however, the specific moral standards which predict depression may vary with culture and the characteristics of the sample. 相似文献

We suggest that a consideration of consumer self-evaluations is fundamental to understanding the conditions under which it is more advantageous to present person or product pictures in print advertisements. We build on the basic human motives of self-enhancement and self-verification to propose that the specific self-esteem level of consumers, in the domain relevant for the category, differentially affects their responses to picture type. Specifically, for consumers with low (high) domain-specific self-esteem, depicting a product (person) in the advertisement enhances attitudes toward the advertisement more than depicting a person (product). In two studies, we demonstrate the proposed matching relationships using two different domains of consumer self-evaluation: appearance self-esteem and academic self-esteem. We also show that increased and more fluent generation of self-related mental imagery drives the observed improvement in attitudes toward the advertisement. Our findings suggest direct implications for advertising design. 相似文献
