C.T.Patrick Diamond 《Int J Intercult Relat》1982,6(4):395-420
This article discusses Kelly's theory of personal constructs and its Repertory grid technique as means of revealing the nature of cultural differences and similarities. It shows how Kelly's theory relates to cognitive theory, implicit personality theory and subjective culture theory. According to Kelly, people and groups are best understood in terms of the ways they anticipate events. People are all psychologists since they employ constructs. These bases of discrimination are bipolar in nature and open to revision. A group's culture is summarized by its members' shared superordinate constructs. Kelly's Commonality Corollary explains that members of a group are similar because they use the same constructs to order events. Kelly's Sociality Corollary states that, in order to enter into a relationship with others, people need first to subsume the others' personal constructs. His custom-built Repertory grid elicits constructs by having a person decide how in a matrix other people, for example, are similar and different. In the rated grid form, each person or element is rated from most to least on the positive pole of each construct. Either principal components or cluster analysis or multidimensional scaling can reveal the interviewed person's superordinate dimensions of appraisal. As an emic technique, the grid is contrasted with the semantic differential and other fixed-format tests. A review of the personal construct literature shows that many individuals and cultural groups have been explained in their own terms. In this research, difference is construed as interesting and others are understood by construing their construction processes as a first step towards approval. 相似文献

Maximal-intensity isometric and dynamic exercise performance after eccentric muscle actions 总被引:3,自引:2,他引:1
A well-documented observation after eccentric exercise is a reduction in maximal voluntary force. However, little is known about the ability to maintain maximal isometric force or generate and maintain dynamic peak power. These aspects of muscle function were studied in seven participants (5 males, 2 females). Knee extensor isometric strength and rate of fatigue were assessed by a sustained 60 s maximal voluntary contraction at 80 degrees and 40 degrees knee flexion, corresponding to an optimal and a shortened muscle length, respectively. Dynamic peak power and rate of fatigue were assessed during a 30 s Wingate cycle test. Plasma creatine kinase was measured from a fingertip blood sample. These variables were measured before, 1 h after and 1, 2, 3 and 7 days after 100 repetitions of the eccentric phase of the barbell squat exercise (10 sets x 10 reps at 80% concentric one-repetition maximum). Eccentric exercise resulted in elevations in creatine kinase activity above baseline (274+/-109 U x l(-1); mean +/- s(x)) after 1 h (506+/-116 U x l(-1), P < 0.05) and 1 day (808+/-117 U x l(-1), P < 0.05). Isometric strength was reduced (P < 0.05) for 7 days (35% at 1 h, 5% at day 7) and the rate of fatigue was lower (P < 0.05) for 3 days at 80 degrees and for 1 day at 40 degrees. Wingate peak power was reduced to a lesser extent (P < 0.05) than isometric strength at 1 h (13%) and, although the time course of recovery was equal, the two variables differed in their pattern of recovery. Eccentrically exercised muscle was characterized by an inability to generate high force and power, but an improved ability to maintain force and power. Such functional outcomes are consistent with the proposition that type II fibres are selectively recruited or damaged during eccentric exercise. 相似文献

Patrick Coldstream 《Higher Education Quarterly》1989,43(2):99-107
This paper explores the concept of matching the activities of higher education institutions to the needs of a wider society. The author recognises that universities and polytechnics have absolute loyalties beyond the market-place. Nevertheless, now as never before there is an environment in which mututally advantageous relationships between higher education and the world of industry can be developed. 相似文献
