The felge, or undersomersault, on parallel bars has become an important skill in men's artistic gymnastics as it forms the basis of many complex variations. To receive no deductions from the judges, the felge must be performed without demonstrating the use of strength to achieve the final handstand position. Two male gymnasts each performed nine trials of the felge from handstand to handstand while data were recorded using an automatic motion capture system. The highest and lowest scoring trials of each gymnast, as determined by four international judges, were chosen for further analysis. The technique used by each gymnast was optimized using a computer simulation model so that the final handstand position could be achieved with straight arms. Two separate optimizations found different techniques identified in the coaching literature that are used by gymnasts. Optimum simulations resulted in improved performances through a combination of increased vertical velocity and height of the mass centre at release. Although the optimum technique found close to the gymnasts' own technique was more demanding in terms of the strength required, it offered the potential for more consistent performance and future developments in skill complexity. 相似文献

This case is about Major League Baseball and the Dominican Republic. We explore how Major League Baseball has used this Caribbean island as an inexpensive labor market and the social problems of the situation. Specifically, we examine Corporate Social Responsibility, the leadership of Sandy Alderson, ethics and the various stakeholders involved. We also look into possible reform alternatives while addressing the central question: What is in the best interest of the players? 相似文献

Teaching and learning in digital environments: The resurgence of resource-based learning 总被引:4,自引:0,他引:4
Janette R. Hill Michael J. Hannafin 《Educational technology research and development : ETR & D》2001,49(3):37-52
The digital age has not simply changed the nature of resources and information; it has transformed several basic social and
economic enterprises. Contemporary society—the settings where we live, work, and learn—has likewise changed dramatically.
Both the amount of information and access to it have grown exponentially; a significant potential for using varied resources
in numerous ways for instruction and learning has emerged. However, several issues related to the educational uses of varied
resources (e.g., people, place, things, ideas) must be addressed if we are successfully to implement resource-based learning
environments. In this paper, we trace the changing nature of resources and perspectives in their use for learning in the digital
age, describe the overarching structures of resource-based learning environments, and identify key challenges to be addressed. 相似文献

Since Grossman’s seminal paper in 1972, there have been a number of studies concerning the effect of education on health and health care demand. Though several studies have distinguished between preventive and curative care, no study has investigated the effects of general education on the utilization of unnecessary emergency department use. We test whether general education reduces “potentially unnecessary” emergency department utilization and provide a measure of the resulting private benefits associated with increased education. Our results partially confirm our hypothesis regarding “potentially unnecessary” emergency department use. We find that moving from a high school to greater than high school education appears to reduce “potentially unnecessary” emergency department use, with the impact being greater among the insured. However, though reducing the education level from high school to less than high school increases “potentially unnecessary” emergency department use among the insured as predicted, it has the opposite impact on the uninsured. 相似文献

This article summarizes a reformulation of the main findings and perspectives from a cross-sectional and longitudinal qualitative study of the development of 100 counselors and therapists. The results are presented as a phase model and as a formulation of 14 themes of counselor/therapist development. The following six phases are described: The phases of the lay helper, the beginning student, the advanced student, the novice professional, the experienced professional, and the senior professional. The themes describe central processes of counselor/therapist development. The themes are addressing different issues such as shifts in attentional focus and emotional functioning, the importance of continuous reflection for professional growth, and a life-long personal/profession integration process. Sources of influence for professional functioning and development are described. The results show consistently that interpersonal experiences in the personal life domain (early family life and adult personal life) and the professional life domain (interacting with clients, professional elders, and peers) are significant sources of influence for professional development. 相似文献

Interest in career development and career counseling is growing in Korea. Nevertheless, neither the research nor the literature
adequately address the question as to what applications can be cross-culturally transferred from career counseling centers
in the United States to Korea. This study qualitatively examines the practice of career counseling in seven university career
counseling centers in the United States in a search for concepts and methods that may be cross-culturally applied to Korean
universities. Nine categories of data emerged in our qualitative analysis of information gathered: (a) types of systems; (b)
staff; (c) services provided; (d) career assessments; (e) alumni networks; (f) workshops and outreach; (g) publicity; (h)
information technology; and (i) facilities. Applications and ideas for the Korean context, limitations, and suggestions for
future research are discussed. 相似文献

Notetaking is a universal activity in college lecture courses, but little research has been done to examine students' perceptions of this study strategy as it relates to their overall study routine. In the current study, students in a large lecture course in introductory macroeconomics were asked to complete the Notetaking Perceptions Survey (NPS), an instrument that assesses students' perceptions of the worth or value of notetaking, their perceived level of notetaking activity, and their degree of confidence about their own notetaking skill. Additionally, students' learning style, as assessed by the Learning Style Inventory (Smith and Kolb, 1986), gender, high school rank, and year of high school graduation were included as predictor variables within a multiple regression analysis to predict scores on the there notetaking perception factors. Notetaking perceptions were predicted by one of the learning style dimensions and by gender. The relationships of final course grades with the three notetaking factors from the NPS and the other learner characteristics were also determined. Grades were predicted by one of the notetaking perception factors and by high school rank. 相似文献
