Discontinuous precipitation in a two-phase Zn-rich Zn-6.3at.%Ag alloy has been studied. It has been shown that the eta/epsilon interphase boundaries have the ability to initiate discontinuous precipitation as do the eta/eta grain boundaries. The back-polishing method is used to show the interconnection between a discontinuous precipitate colony and the eta/epsilon interphase boundary. The reaction front velocity of discontinuous precipitation initiated at the eta/eta grain boundary is 12-90% higher than that of discontinuous precipitation initiated at the eta/epsilon interphase boundary under various ageing temperatures.  相似文献

Abstract

The aim of the article is to look at the process of ‘reconfiguration’ of Jehovah's Witnesses' identity in the area which comprises the former German Democratic Republic (GDR) and societal and state responses to it. Over 20 years after the fall of the Berlin Wall Jehovah's Witnesses are one of the largest minority religions in eastern Germany. Being a religious minority in a region that is both stigmatised by the socialist past and considered the most secular part of Europe raises a number of issues. Among these, the question of the identity of the movement and its societal reception plays a crucial role. During the time of the GDR Witnesses built their identity against the state and its functionaries. Persecutions not only destroyed or changed the lives of many members but also strengthened them. Moreover, being a victim of the socialist system provided a basis to build upon after the Unification. A 16-year struggle for the status of public law corporation in the ‘new’ state – accomplished in 2006 – only reinforced such identification. Nowadays, however, Witnesses in the former GDR have to face a new challenge: building a reliable identity not in opposition to the state or upon their role as victims, but only on the basis of their religion.  相似文献

ABSTRACT

Exposure to negative life stress has been associated with difficulty retrieving memories for specific autobiographical events, with important consequences for the emergence of emotional disorders. We examined whether social support can protect against the effects of negative events on memory specificity. University students (N?=?143) were assigned to groups based on whether or not they experienced a negative stressor, operationalised as whether or not their recent exam performance was in line with their expectations. After receiving their exam results (T1), and one month later (T2), participants completed measures of memory specificity, their attitudes towards themselves and the occurrence of other stress-related events. Participants also completed a general measure of perceived social support from friends, family, and significant others, and an equivalent measure for social support related to performance. For participants who experienced an exam-related stressor, reduced performance-specific social support from friends was associated with reduced memory specificity at T2, even when accounting for T1 memory specificity, individual differences in attitudes towards self, the experience of additional stressors, and gender. No such relation was present for participants who did not experience a stressor. These findings provide new understanding of the influence of social variables on autobiographical memory specificity.  相似文献

Terror management theory (TMT) proposes that self-esteem serves as a defense against the fear of death. Previous research has suggested that independent self-esteem is more salient in individualist cultures, whereas interdependent self-esteem is more salient in collectivist cultures. Thus, we hypothesized that in collectivist cultures, independent self-esteem would play a lesser role and interdependent self-esteem a greater role in terror management, compared to individualist cultures. The results support this prediction. In Study 1, personal self-esteem was negatively associated with death anxiety in samples from a Western (Austria) and Eastern (China) culture. However, both self-liking and self-competence were negatively associated with death anxiety among Austrian participants, but only self-liking (and not self-competence) was so among Chinese participants. Surprisingly, collective self-esteem was not significantly correlated with death anxiety. Yet, Study 2 showed that among Chinese participants, relational self-esteem was negatively associated with death anxiety. Study 3 examined the roles of relational versus personal self-esteem in moderating the effects of mortality salience on worldview defense. Among Chinese participants, relational rather than personal self-esteem increased the defense of worldviews centered on collectivist-Chinese values following mortality salience (Study 3a). In contrast, among Austrian participants, personal rather than relational self-esteem attenuated the effect of mortality salience on the defense of individualist-Austrian worldviews (Study 3b). Self-esteem serves a terror management function in both collectivist and individualist cultures; however, the differences between cultural worldviews determine the type of self-esteem that is more relevant to terror management processes.  相似文献

The present study explored the validity of constriction as an indicator of depression. Twenty-five patients displaying constriction in their Bender records and 25 patients not showing this indicator were compared with regard to MMPI Depression scores. A significant difference was found between D scores of these two groups (p<.05), supporting the validity of the indicator as an index of depression. Constriction was found to be infrequent, occurring in only 5.5% of the patient records. Although the indicator seems to be of some value as an indicator of depression its utility is lessened due its low rate of occurrence.  相似文献

Previous studies documented that butches showed a masculine profile and femmes showed a feminine profile in gender roles. This study examines the association between butch or femme lesbian identity and empathizing–systemizing (E–S) cognitive styles among 588 lesbian and bisexual women from multiple cities in China. Empathizing and systemizing were assessed using two different abbreviated 8-item scales drawn from longer original scales. There were significant differences in systemizing among butch–femme identity, with butches scoring higher than femmes, but no significant differences in empathizing. The discrepancy in empathizing–systemizing scores reflects individual differences in dispositional cognitive style. A higher proportion of femmes exhibited an E > S cognitive profile, while a higher proportion of butches exhibited an S > E cognitive profile. Sexual stereotyping based on masculinity/femininity, or biology, may be related to butch–femme difference in cognitive style. In studies on sexual orientation, researchers should pay more attention to butch–femme subgroup differences among lesbians.  相似文献

Resumen

El trabajo examina el efecto de cambios internos atribuibles al ciclo menstrual en la responsividad y condicionamiento psicofisiológico de un grupo de mujeres normales con ciclos naturales. Los sujetos fueron examinados Premenstrualmente (PM) o Intermenstrualmente (IM), utilizando como variables dependientes medidas psicofisiológicas (Conductancia de la Piel y Tasa Cardíaca) y cuestionarios. Los sujetos IM mostraron mayor responsividad y habituación en la actividad cardíaca y menores latencies de recuperación en la conductancia de la piel ante estimulación auditiva intensa, así como mayor condicionamiento en la conductancia de la piel (respuestas al segundo intervalo) que los sujetos PM. Las medidas actuales y retrospectivas de estados emocionales mostraron mayor afecto negativo (fatiga y tensión) en los sujetos PM y en l a fase premenstrual. Estos resultados son comparados con los de estudios similares realizados con pacientes fóbicas y son discutidos en términos de diferentes estados emocionales y de activación fisiológica asociados a las fases menstruales examinadas.  相似文献
