This essay analyzes the ways in which Kent State, the made‐for‐TV docudrama, purified the image of William Knox Schroeder‐one of the four students killed on May 4, 1970, by Ohio National Guardsmen on the Kent State University campus. The author was a boyhood friend of Schroeder, his roommate at Kent State University at the time of his death, and an observer of many of the major events of the Kent State affair. This essay views the making of a docudrama as a complex problem to be solved and characterizes a docudramatist as a less‐than‐perfect decision maker. Also, this essay views Kent State as a real‐fiction through which the act of rhetorical purification was accomplished. The paper discusses the docudrama's efforts in this regard by analyzing important scenes in which inaccuracies are presented in order to achieve the purification of Schroeder's image. 相似文献

Over the last decade universities across the world have been grappling with quality and quality assurance issues. In several countries national policies on higher education quality assurance have been evolving, mostly with the purpose of putting external systems of quality assurance in place. In many instances, these policies and systems had less effect on the quality of teaching and learning than had been expected. This paper serves as a comparison of national quality policy developments in two countries, Australia and South Africa, and goes on to investigate the emerging tensions in quality policy processes in these countries. Whereas a number of similarities were discerned, differences were as evident, verifying the underlying assumption of the authors that notions of quality, and quality policies and their implementation are very much dependent on the particular localised contexts in which they exist. 相似文献

The study of childhood stress provides a useful perspective for assessing children's emotional status. Thematic projective techniques, like the Children's Apperception Test (CAT), may be useful in exploring children's perception of stress. For this purpose, a need-threat analysis is recommended to identify those underlying needs and threats that are likely to make a particular event or situation important, and hence potentially stressful, to an individual child. This paper introduces a scoring system for the CAT based on the analysis of thematic data in terms of five need-threat binaries, which serve as scoring categories. Preliminary data on reliability are presented. 相似文献

Body position is known to alter power production and affect cycling performance. The aim of this study was to compare mechanical power output in two riding positions, and to calculate the effects on critical power (CP) and W′ estimates. Seven trained cyclists completed three peak power output efforts and three fixed-duration trial (3-, 5- and 12-min) riding with their hands on the brake lever hoods (BLH), or in a time trial position (TTP). A repeated-measures analysis of variance showed that mean power output during the 5-min trial was significantly different between BLH and TTP positions, resulting in a significantly lower estimate of CP, but not W′, for the TTP trial. In addition, TTP decreased the performance during each trial and increased the percentage difference between BLH and TTP with greater trial duration. There were no differences in pedal cadence or heart rate during the 3-min trial; however, TTP results for the 12-min trial showed a significant fall in pedal cadence and a significant rise in heart rate. The findings suggest that cycling position affects power output and influences consequent CP values. Therefore, cyclists and coaches should consider the cycling position used when calculating CP. 相似文献

The forward skating start is a fundamental skill for male and female ice hockey players. However, performance differences by athlete’s sex cannot be fully explained by physiological variables; hence, other factors such as skating technique warrant examination. Therefore, the purpose of this study was to evaluate the body movement kinematics of ice hockey skating starts between elite male and female ice hockey participants. Male (n = 9) and female (n = 10) elite ice hockey players performed five forward skating start accelerations. An 18-camera motion capture system placed on the arena ice surface captured full-body kinematics during the first seven skating start steps within 15 meters. Males’ maximum skating speeds were greater than females. Skating technique sex differences were noted: in particular, females presented ~10° lower hip abduction throughout skating stance as well as ~10° greater knee extension at initial ice stance contact, conspicuously followed by a brief cessation in knee extension at the moment of ice contact, not evident in male skaters. Further study is warranted to explain why these skating technique differences exist in relation to factors such as differences in training, equipment, performance level, and anthropometrics. 相似文献
