The development of peak performances is a main research focus in sports science. It is unclear how many former top junior athletes achieve success in the elite class later. The aim of the present study was to examine the careers of athletes who participated in major junior or adult/elite cycling events using prospective and retrospective analysis of competition results. The official results of major junior (age < or = 18 years) and elite (age > 18 years) cycling races from 1980 to 2004 were analysed. Age-related aspects, career lengths, and success were compared between riders who presented results in both junior and elite races (JUNIOR ELITE) and riders who had no junior race results (ELITE ONLY). Altogether, 27,454 results of 8004 athletes from 108 countries were collected. We found that 29.4% of the elite athletes had participated in junior World Championships, and that 34% of the participants in junior World Championships later participated in major elite competitions. JUNIOR ELITE athletes are significantly more successful in several cycling disciplines and have their first and last elite result at a younger age than ELITE ONLY athletes. No difference was found in career lengths. The data presented here emphasize the importance of long-term training programmes in the development of peak performance in cycling. 相似文献
Strategic planning is a common practice at higher education institutions. Furthermore, it is assumed that identifying organizational values is an essential part of the planning process. Values are often construed as foundational elements of strategic thinking that serve to ‘drive the plan’. However, there is little conceptual or applied evidence to support the effectiveness of coupling organizational values articulation with strategic planning processes. The author reports on a study that was designed to effectively conceptualize organizational values, and foster a deeper understanding of organizational values application in higher education administration. This research involved a textual analysis of strategic planning documents pertaining to organizational values from Canadian universities. Research results offer concrete ways to conceptualize and apply organizational values within university settings. The results serve as a foundation to explore small-group-focused approaches to both policy creation and evaluation pertaining to the articulation of organizational values in university administration.
The development of declarative knowledge was examined within the parameters of movement-based curricula. Declarative knowledge represents factual or foundational knowledge frequently articulated as curriculum content. A semantic ordered tree technique was used to investigate the knowledge structures of three groups of teacher preparation subjects (novice, coursework, student teacher) and one group of elementary physical education teachers (experts). Structures were examined based on frequency and coherence criteria. ANOVA was used to examine differences between groups. Results suggested that declarative knowledge appeared to develop in complexity from novice to expert within the parameters of concept-based movement curricula. The Active Structural Networks Theory was used to interpret structural development through the accretion, tuning, and restructuring phases. Knowledge structures of the novice and coursework groups seemed to represent accretion, whereas those of student teachers and experts represented tuning and restructuring. 相似文献
The University of Minnesota Medical School has an innovative curriculum, called Didactic/Selective, which provides third- and fourth-year medical students with multidisciplinary and multispecialty courses. Within this framework, the Bio-Medical Library planned a course to teach the knowledge and skills necessary for library research and information management. It included (1) searching case-related topics in print indexes, (2) formulating and processing MEDLINE searches on BRS Colleague, (3) building a personal file with PC-File or Notebook, and (4) exploring various methods for current awareness. Students' evaluations were positive, with the majority indicating that they found the course interesting and the knowledge gained substantial. 相似文献
Questionnaire data from 137 panel chairs at the 2003 Academy of Criminal Justice Sciences meeting in Boston reveal respondent perceptions of the conference site, overall impressions of the conference, as well as panelist attendance, and the quality of information presented by panelists. The findings reveal high marks for the conference space, hotel rooms, and the city of Boston itself, resulting in an overall positive conference experience, but responses also highlight several areas of concern, including panelist attendance problems and presentation etiquette. Recommendations are provided, which may foster positive, incremental change at future ACJS annual meetings. 相似文献
This article, which offers a critical reassessment of the underlying rationale for universal service policies, argues that public policies designed to promote universal telecommunications access are simply a form of wealth redistribution. By reconceptualizing universal service subsidies in this way, one can obtain a more realistic assessment of the proper scope and limits of universal service policies. Universal service policies, at best, can play a supplementary role. Economic reforms that encourage investment and promote robust competition are more fundamental to the development of an ubiquitous infrastructure than government subsidies. The redistribution of wealth via telecommunications can ameliorate inequalities, but it cannot eliminate their causes, and advocates should stop pretending that it can. Furthermore, universal service advocates must become more aware of the political and economic risks and pitfalls that are inherent in the process of wealth redistribution. 相似文献
