In this study a method for determining elbow extension and elbow abduction for a cricket bowling delivery was developed and assessed for Jenny Gunn who has hypermobility in both elbows and whose bowling action has been repeatedly queried by umpires. Bowling is a dynamic activity which is assessed visually in real time in a cricket match by an umpire. When the legality of a bowler's action is questioned by an umpire a quantitative analysis is undertaken using a marker based motion analysis system. This method of quantifying elbow extension should agree with a visual assessment of when the arm is "straight" and should minimise the effects of marker movement. A set of six markers on the bowling arm were used to calculate elbow angles. Differences of up to 1° for elbow extension and up to 2° for elbow abduction were found when angles calculated from the marker set for static straight arm trials were compared with measurements taken by a chartered sports physiotherapist. In addition comparison of elbow extension angles at ball release calculated from the markers during bowling trials with those measured from high speed video also showed good agreement with mean differences of 0°±2°. 相似文献

Background: In 2007 the University Health Sciences Librarians Group (UHSL) merged with the University Medical Schools Librarians Group (UMSLG) to form the University Health and Medical Librarians Group (UHMLG). This paper traces the course of health librarianship in the UK which led to this event, from the perspective of the UHSL. Methods: The narrative has been developed from the Executive Committee minutes, newsletters and reports of events organized by the UHSL. Summary: The UHSL evolved from the Council of Polytechnic Librarians (COPOL) Health Sciences Group and the Standing Conference of National and University Librarians (SCONUL) Health Sciences Group. It sought to represent the views of health librarians working in the university sector. It also provided, through newsletters and study days, information, networking opportunities and professional development. UHSL collaborated with other relevant organizations to further its aims. Conclusion: The structure of professional support groups within health librarianship reflects the evolving nature of the health service, higher education and the social changes driven by technological developments. 相似文献

Rats that were given nonreinforced preexposure to either a warning signal or a safety signal were significantly retarded in the subsequent learning of a two-way shock-avoidance response compared to rats that were not preexposed. These results are consistent with Mackintosh’s “learned-irrelevance” formulation of latent inhibition. They do not support a prediction derived from an extension of Kalat and Rozin’s “learned-safety” hypothesis. These findings suggest that preexposures in the total absence of aversive events do not endow a stimulus with safety properties. 相似文献

Individualized instruction is aphylum rather than aspecies of approaches to teaching. Problems of definition, usage, and shifting point of view contribute to the increasingly indiscriminate use of the term. One way of analyzing the collection of individualized programs, practices, and materials is to sort outfamilies of approaches and to organize them into a simple classification system according to their distinguishing characteristics. The differentspecies within families can be more precisely described in profiles that outline the treatment given to each major element of instruction. The ideal implicit in the programs seems to be separate, appropriate instruction for each student, but the ideal program has yet to be developed.
This article is based on a monograph in preparation at Teachers College Press, Teachers College, Columbia University. It will appear in the seriesTheory and Research in Teaching, A. A. Bellack, general editor. 相似文献
Résumé L'Instruction individualisée est unphylum plûtot qu'uneespèce d'approche à l'enseignement. Les problèmes de définition, d'usage, et de point de vue changeant contribuent au fait qu'on emploie ce terme de plus en plus sans discrimination. Une méthode d'analyser la collection des programmes et des matériaux individuels est de classer par catégories desfamilles d'approches selon leurs caractéristiques spécifiques. On peut décrire les divers genres dans les familles de façon plus précise en esquissant la méthode de traiter chaque élément d'instruction. II semble que l'idéal implicite des programmes est l'instruction séparée et propre à chaque étudiant, mais on n'a pas encore développé le programme idéal.
