对体操运动员自我时机控制能力某些因素的探讨

在跳台上,用自制“全圆弹性跳台开关”和记时器对国家体操少年优秀选手17人和儿童体操初学者20人的复制跳跃腾时的准确性、左右转体的均称性、复制腾时的迁移与干扰、运动节奏、快转90°和慢转90°的腾时时距和角度误差进行测定,根据公式: 慢转体腾时-快转体腾时(即时距)×(1-角误均数/100)=时空指数,求得每位被试的“时空指数”。以探讨体操运动员自我时机控制能力的某些因素中,哪些是潜在的,哪些是习得的,二者又如何协同发展。明确它,以便帮助运动员养成与发展自我时机控制能力问题。     

少年赛中情绪影响运动成绩的研究

实验以46名少年为对象,以400m跑为内容,在被试者不知道的情况下,把他们分为鼓励(表扬)组和挫折(批评)组。预先测得他们400m跑的平时成绩,做为实验后被试自己与自己成绩比较的出发点。具体实验之前,告诉被试者,这次测验400m跑,既看“达标”如何?也看“技评”如何? 实验是在400m跑途中,于100m,200m,300m处各设数人为“技评”鉴别者。每两个人一起跑,一个人受“表扬”,一个人挨“批评”。 结果,接受积极刺激的少年,多数唤起增力情绪,并做出积极的反应,但也有少数人出现了减力情绪,做出消极的反应。而接受消极刺激者,正与此相反。 表扬比批评具有更大的动力性质,教师在教学中宜多用表扬,对少年的表扬与批评,要注意年龄与性别特点。

Traditional Confucianism in modern China: Ma Yifu’s ethical thought

Modern neo-Confucianism is studied at two levels, one is at the historical level and the other at the academic level. Modern neo-Confucianism at the historical level was developed in the modern context, but its basic content belongs to the traditional Confucianism or the study of Confucian classics. Modern neo-Confucianism at the academic level recognizes both the deficiencies of the traditional Confucianism and rationality of western learning, and dedicates itself to the modernization of Confucianism. Though Ma Yifu’s moral philosophy is developed in the context of modern Chinese culture, it fails to deal with the problem of modern transformation of Confucian ethical values and its content still belongs to the traditional Confucianism. So it should be labeled as the modern neo-Confucianism in the historical sense. In this paper, the author makes a systematic exploration and an evaluation of Ma Yifu’s ethical thought. __________ Translated from Lunlixue Yanjiu 伦理学研究 (Studies in Ethics), Vol. 18, 2005 (4) by Yang Xu     

Learning and Living Systemic: Exploring the Personal Effects of Family Therapy Training

Despite growing recognition that systemic family therapists need to be adept at personal reflection and managing the therapeutic relationship, little research has explored the effects of training beyond the development of skills. This article provides a report on a qualitative study focussed on the personal effects of family therapy training, with particular reference to the aspects of training that foster personal reflection and growth. Twenty three trainees from three training institutions were interviewed, utilizing the practices of grounded theory. Trainees reported a deepening relational awareness, which applied to both personal and professional domains and included shifts in perspectives on relationships with loved ones. Five aspects of training were identified as responsible: (1) personally challenging experiences with clients; (2) supervisors who live the paradigm; (3) the demystification of theory; (4) a safe supervisory space; and (5) the development of trusting peer relationships. Interns also described, in turn, how their personal development affected their clinical work, particularly in the development of compassion and empathy. This study serves to highlight training practices that support reflective practice in systemic family therapy.     

Gene knockout of insulin-regulated aminopeptidase: Loss of the specific binding site for angiotensin IV and age-related deficit in spatial memory

The AT₄ ligands, angiotensin IV and LVV-hemorphin 7, elicit robust effects on facilitating memory by binding to a specific site in the brain historically termed the angiotensin AT₄ receptor. The identification of the AT₄ receptor as insulin-regulated aminopeptidase (IRAP) is controversial, with other proteins speculated to be the target(s) of these peptides. In this study we have utilized IRAP knockout mice to investigate IRAP in the brain. We demonstrate that the high-affinity binding site for angiotensin IV is absent in IRAP knockout mice brain sections in parallel with the loss of IRAP immunostaining, providing irrefutable proof that IRAP is the specific high-affinity binding site for AT₄ ligands. However, our characterization of the behavioural phenotype of the IRAP knockout mice revealed a totally unexpected finding. In contrast to the acute effects of IRAP inhibitors in enhancing memory, deletion of the IRAP gene resulted in mice with an accelerated, age-related decline in spatial memory that was only detected in the Y maze paradigm. Moreover, no alterations in behaviour of the IRAP knockout mice were observed that could assist in elucidating the endogenous substrate(s). Our results highlight the importance of analysing the behavioural phenotype of knockout mice across different ages and in distinct memory paradigms.     

Synthesized views can improve face recognition

It is well known that a new face studied from one view is often difficult to identify from another. This viewpoint dependence has detrimental implications for forensic practice. To compensate for this problem, we employed synthesized face images in the training session of a standard old/new recognition task. Observers in the experimental conditions learned one or more synthesized face images along with an original photograph of the face in a different view, whereas observers in the control conditions learned only the original photograph of the face. It was found that the experimental conditions consistently produced better recognition accuracy than the control conditions. We conclude that synthesized face views can be used to facilitate person identification in forensic applications. Copyright © 2008 John Wiley & Sons, Ltd.     

Career Choice Barriers, Supports, and Coping Strategies: College Students' Experiences

This study used qualitative methods to examine the perceived influences on college students' selection and implementation of career choices. Students at two universities participated in a structured interview examining (a) factors that had affected their choice of occupational field, (b) supports and barriers to pursuing their choices, and (c) methods they had used to cope with choice barriers. Across both samples, person factors (e.g., interests) and work-relevant experiences were frequently cited bases for choice selection, although contextual factors (e.g., financial constraints, social supports) were among the most salient barriers and supports to choice implementation. Each sample also reported choice selection and implementation influences and coping strategies that may have been linked to their particular environmental and developmental contexts. Implications of these findings for career theory, research, and practice are considered.
