Complete solid-state amorphization has been realized in elemental Se by means of mechanical milling of crystalline Se powder. Quantitative X-ray diffraction and thermal analyses were employed to characterize the amorphization process and indicated that the amorphization onset corresponds to a critical crystallite size and a drop in microstrain. During the major amorphization process, the remaining crystallite size remains unchanged with a constant lattice expansion. A new kinetics model of crystallite destabilization is proposed for the solid-state amorphization which satisfactorily explains the experimental observations.  相似文献

The theory of planned behavior has been applied to sports and exercise behaviors. According to this theory, human intention to take action in a specific context is guided by three antecedents: attitude, subjective norm, and perceived behavioral control. Behavioral intention mediates the relationships between these three considerations and its ultimate performance. However, this theory has seldom been applied to the behaviors of spectators of sporting events. A sample of 269 volleyball spectators in Taiwan was studied to examine whether people's intention mediated their attitudes, subjective norms, and perceived behavioral control toward a given behavior, watching the 2010 Fédération Internationale de Volleyball World Grand Prix in Taipei. Regression analyses did not support behavioral intention as a mediator. This result is discussed in the context of planned behavior.  相似文献

Fibromyalgia is a syndrome characterized by the presence of diffuse and chronic musculoskeletal pain of unknown etiology. Clinical diagnosis and the merely palliative treatments considerably affect the patient's experience and the chronic course of the disease. Therefore, several authors have emphasized the need to explore issues related to self in these patients. The repertory grid technique (RGT), derived from personal construct theory, is a method designed to assess the patient's construction of self and others. A group of women with fibromyalgia (n = 30) and a control group (n = 30) were assessed using RGT. Women with fibromyalgia also completed the Fibromyalgia Impact Questionnaire and a visualanalogue scale for pain, and painful tender points were explored. Results suggest that these women had a higher present self-ideal self discrepancy and a lower perceived adequacy of others, and it was more likely to find implicative dilemmas among them compared to controls. These dilemmas are a type of cognitive conflict in which the symptom is construed as "enmeshed" with positive characteristics of the self. Finally, implications of these results for the psychological treatment of fibromyalgia are suggested to give a more central role to self-identity issues and to the related cognitive conflicts.  相似文献

Consumer ethics is the moral principles and standards that guide consumers to determine the certain consumption behaviors are ethically right or wrong. Whereas cultural and personal dimensions are crucial constructs affecting individual ethical attitudes and behaviors, few studies consider Confucian dynamism and the role of money in consumer ethics. Confucian dynamism, a cultural dimension based on Confucianism, has played a central role in guiding moral obligations and ethics in human relations in several East Asian countries. Thus, this study tested its hypotheses using a sample of 521 respondents obtained via a systematic random sampling technique. The authors find that individuals with a higher tendency to Confucian dynamism are less tolerant of unethical practices. These findings also show that the role of money partially influences consumer ethical beliefs. Finally, we examine the impact of demographic variables and find age and education affect consideration of ethical values.  相似文献

医学伦理学教育中长期存在的一些问题尚未很好解决.由于较多强调课程的道德教育功能,对其作为独立学科存在的性质和意义仍重视不够,医学伦理学是进行道德分析、准则与价值评判的理论体系,通过医学伦理学的学习和训练,应使学生能够对有关问题在广阔的背景中进行深层次思考并做出独立判断.我们应在进一步更新观念的基础上,改进哲学、伦理学基础教育,以促进医学伦理学教育的发展,而其意义已远超出医学伦理学之外.  相似文献

While prior studies have focused on the effect of leader–member exchange (LMX), representing a dyadic differentiated exchange relationship between a leader and followers, on employees’ job-related outcomes, how LMX at the group level influences one’s life domain has been ignored. The present study shifted attention to the relationship between LMX mean and employee life satisfaction as well as the boundary conditions. Using a sample of 471 employees from 53 groups and hierarchical linear modeling, we examined the cross-level main effect of LMX mean on life satisfaction and the moderation of group power distance and individual political skill. The results revealed that LMX mean had a work-to-life spillover effect on employee life satisfaction. Employee political skill positively moderated the relationship between LMX mean and life satisfaction, whereas group power distance negatively moderated the relation. Theoretical and practical implications were further discussed.  相似文献
