坐标变换的推广     

李冬萍 《鄂州大学学报》2005,12(6):56-58

研究表明，物理学中最普遍的坐标变换并不是洛伦兹变换，洛伦兹变换的不变性原理没有普遍意义。该文对加速系统、亚光速和超光速系统研究分析了一个普遍适用的统一的新的坐标变换——“梁氏变换”。  相似文献

Becoming a ‘good coach’     

Frank Jacobs  Inge Claringbould  Annelies Knoppers 《Sport, Education and Society》2016,21(3):411-430

The purpose of this paper was to gain insight into how coaches problematized their coaching practices and the process in which they engaged to become what they perceived to be better coaches using a course based on critical reflective practice. We assumed that constant critical self-reflection would enable coaches to move closer to their individual idea of a ‘good coach.’ Scholars and coaches collaborated to develop course content. The course was built on principles of rational-emotive education. We drew on Foucault's conceptualization of self-constitution or modes of subjectivation and confessional practice and Knaus' approach to teaching for our analytical framework. Thirty-five coaches participated in this study. The data consisted of semistructured interviews, field notes, open-ended questionnaires and focus group. The results are presented per mode of change or transformation. We explored how coaches wanted to transform their coaching practice (ethical substance), how they defined a good coach (mode of subjection), how they worked on change (ethical work) and how they transformed themselves (telos). To gain further insight into this process, we also examined narratives of three coaches as they described why and how they changed. The practice of critical reflection seemed to meet the needs of the coaches involved in the study. They used it to continually examine their behavior and their normalized taken-for-granted beliefs and to transform themselves in the direction of their idea of a ‘good coach.’ Ontological reflection was seen as a tool and a process that requires continual practice.  相似文献

传统思维方式与文艺经验批评方法的形成     

董希文  杜捷  梁亮  徐加美 《牡丹江教育学院学报》2008,(6)

中国传统思维重视类比?和谐整体?辩证、妙悟等方式方法,对文艺经验批评方法的形成具有重要的影响。随着现代性的不断深入,中国文艺批评逐渐失去了传统文化的根脉。把中国传统文艺批评方法注入到现代文艺批评中,通过扬弃,实现古代文艺经验批评的现代转换,才能形成和发展具有民族特点的当代文艺经验批评方式。  相似文献
