The purpose of the study was to compare young sprint and distance runners for changes in their cardiac dimensions with increased age (10–17 years) or body surface area (1–2 m2). Echocardiographic dimensions were obtained on 73 male track athletes competing in the 1983 National Age Group Track and Field Association championships. Each group of athletes was also compared with a hypothetical normal population (matched for weight and age) generated from prediction equations derived by Henry, Gardin, & Ware (1980). The cardiac dimensions examined were: Left ventricular internal diameter, left ventricular posterior wall thickness, and interventricular septum thickness. The male distance runners (n = 38) had a significantly greater increase in left ventricular posterior wall thickness and interventricular septum thickness with increasing age or increasing body surface area compared to the sprinters (n = 35) or compared to the predicted normal population. The left ventricular internal diameter was not significantly different between the groups. These results indicate that the hearts of male distance runners are undergoing a training hypertrophy whereas the hearts of sprinters are no different than hearts in a normal population. The changes in cardiac dimensions of these young athletes run counter to the generalizations stated for adult athletes: That endurance training enlarges the left ventricular internal diameter, but does not increase the left ventricular posterior wall or interventricular septum thickness. 相似文献

This study argues for the integration of African oral traditions and other elements of traditional learning into the modern school curriculum. It thus contributes to supporting the increased relevance of education to local communities. In particular, using the example of riddles collected from one of the main ethnic groups in Northwestern Tanzania, the Haya people, the present study challenges the views of those social and cultural anthropologists who hold that African riddles have no substantially meaningful educational value. Instead, it is maintained that riddles make an important contribution to children’s full participation in the social, cultural, political, and economic life of African communities, especially by fostering critical thinking and transmitting indigenous knowledge.
Zusammenfassung MÜNDLICHE TRADITIONEN IN AFRIKA: DER ERZIEHERISCHE WERT VON RÄTSELN BEI DEN HAYA IM NORDWESTLICHEN TANSANIA – Diese Studie argumentiert für die Einbeziehung afrikanischer mündlicher Traditionen und anderer Elemente traditionellen Lernens in den modernen schulischen Lehrplan. Sie fördert somit die gestiegene Bedeutung der Bildung für die örtlichen Gemeinschaften. Insbesondere begegnet die vorliegende Studie, indem sie das Beispiel von Rätseln gebraucht, die bei einer der Hauptvolksgruppen im nordwestlichen Tansania, dem Volk der Haya, gesammelt wurden, den Ansichten derjenigen Sozial- und Kulturanthropologen, die behaupten, dass afrikanische Rätsel keinen wesentlich bedeutungsvollen erzieherischen Wert haben. Stattdessen wird die These aufgestellt, dass Rätsel einen wichtigen Beitrag zur vollständigen Teilnahme von Kindern am gesellschaftlichen, kulturellen, politischen sowie wirtschaftlichen Leben afrikanischer Gemeinschaften leisten, besonders durch die Förderung von kritischem Denken und die Weitergabe des Wissens der Eingeborenen.
Resumen TRADICIONES ORALES AFRICANAS: EL VALOR EDUCATIVO DE LAS ADIVINANZAS PARA EL PUEBLO DE LOS HAYA EN EL NOROESTE DE TANZANÍA – Con este trabajo, el autor aboga por una integración de tradiciones orales africanas y de otros elementos de aprendizaje tradicional en los actuales planes de estudios de las escuelas. Al mismo tiempo, hace énfasis en la creciente relevancia que la educación tiene para las comunidades locales. Con este estudio, el autor desafía la posición de aquellos antropólogos sociales y culturales que sostienen que las adivinanzas africanas no tienen ningún valor educativo digno de mención, ante todo presentando el ejemplo de adivinanzas que ha recopilado entre los miembros del pueblo de los haya, uno de los principales grupos étnicos del noroeste de Tanzanía. Por lo contrario, el autor afirma que las adivinanzas promueven en gran medida la participación plena de los niños en la vida social, cultural, política y económica de las comunidades africanas, ante todo porque incentivan el pensamiento crítico y transmiten conocimientos indígenas.
Résumé TRADITIONS ORALES AFRICAINES : LA VALEUR ÉDUCATIVE DES ÉNIGMES CHEZ LES HAYAS DE LA TANZANIE DU NORD-OUEST – Cette étude argumente en faveur de l’intégration des traditions orales africaines et autres éléments de l’apprentissage traditionnel dans le programme d’étude de l’école moderne. Elle contribue ainsi à soutenir la pertinance accrue de l’éducation au sein des communautés locales. En particulier, utilisant l’exemple des énigmes recueillies chez l’un des principaux groupes ethniques de la Tanzanie du Nord-Ouest, le peuple Haya, l’étude présente conteste les vues de ces anthropologues sociaux et culturels qui soutiennent que les énigmes africaines n’ont pas de valeur éducative substantiellement significative. Au lieu de cela, on maintient que les énigmes apportent une contribution importante à la pleine participation des enfants à la vie sociale, culturelle, politique et économique des communautés africaines, spécialement en ce qu’elles favorisent la pensée critique et transmettent les connaissances indigènes.相似文献

Getting a good and relevant education is difficult enough to achieve within a context where social and economic needs are constantly unsettled by political policy. The public funding of the education sector has become a contested arena irrespective of a government’s ideology. Recent graduates from various disciplines from Town Planning to Philosophy report in university destination surveys that they have only found employment in areas unrelated to their academic training – for instance, in supermarkets, restaurants and other low-level service industries. How has it happened that the universalisation of mass higher education has contributed to a disconnect between the individual’s social aspirations and their economic status? What happened to the tacit promise that an extended period of intellectual development would prepare the individual for a life of valuable social contribution and financial security? Part of the answer lies in the success of higher education itself. Its popularity has changed its transformative capacity and allowed operational efficiencies to overrule academic quality. The university, ideally seen as a repository of intellectual intuition, has been remade into yet another modern corporation concerned with the bottom line and financial security. Why has it been necessary to remake the university in the image of the department store, supermarket or bank, and how has it been achieved without more critique? 相似文献

Videos of classroom lectures have proven to be a popular and versatile learning resource. A key shortcoming of the lecture video format is accessing the content of interest hidden in a video. This work meets this challenge with an advanced video framework featuring topical indexing, search, and captioning (ICS videos). Standard optical character recognition (OCR) technology was enhanced with image transformations for extraction of text from video frames to support indexing and search. The images and text on video frames is analyzed to divide lecture videos into topical segments. The ICS video player integrates indexing, search, and captioning in video playback providing instant access to the content of interest. This video framework has been used by more than 70 courses in a variety of STEM disciplines and assessed by more than 4000 students. Results presented from the surveys demonstrate the value of the videos as a learning resource and the role played by videos in a students learning process. Survey results also establish the value of indexing and search features in a video platform for education. This paper reports on the development and evaluation of ICS videos framework and over 5 years of usage experience in several STEM courses. 相似文献

Medical students at the Schulich School of Medicine and Dentistry at The University of Western Ontario in London, Ontario, Canada, learn clinical facts about the hepatobiliary system as transplant surgeon Dr. Vivian McAlister (at the far right) demonstrates Whipple's procedure in the anatomy laboratory. In this issue of ASE, Ullah and colleagues describe an extracurricular student initiative known as the Surgically Oriented Anatomy Program (SOAP), which aims to deliver anatomy teaching from a surgical perspective through the philosophy of “education through recreation”. 相似文献

This study aimed to assess the impact of pre-professional education on students' knowledge and attitudes about aging, including the option of a simulated learning activity. Using a mixed design, groups of nursing and nutrition students (n = 127) were randomly assigned to experience the Aging Game. Pre- and posttest observations included measures of anxiety, attitude and empathy. In the Aging Game, students played the role of an elderly adult with common physical disabilities during various scenarios and then reflected on the experience. As a result, students became more familiar with what being an older adult felt like, and increased understanding and empathy. 相似文献

非形式逻辑出现于上个世纪70年代,它首先是一种寻求更好的大学逻辑教学方式的努力.进而,非形式逻辑学者们逐渐开始触及和探讨越来越多的理论议题,即发展不依赖于形式逻辑的关于论证以及好论证的理解方式.在1998年世界哲学大会上,布莱尔和我阐释了非形式逻辑为哲学所带来的理论后果,其中一点我们称之为"演绎主义的终结".那时我们并未给出演绎主义的定义,而只是把它等同于麦金泰尔的那个精炼的说法:"任何推理,不是演绎的,就是有缺陷的."但现在看来,我们在当时就作出"演绎主义的终结"这一论断,显然是有点为时过早了.因为演绎主义似乎至今都还很有生命力,甚至在那些倾向于非形式逻辑的学者那里它也能得到支持:恩尼斯长期以来都辩护演绎主义是一种论证重构策略,格罗尔克更是致力于辩护它是一种论证评价理论.在本文中我将论证,非形式逻辑最好被理解为一种不诉诸于演绎技巧和演绎规范的逻辑研究.当我们意识到演绎和演绎主义已经如何深深地扎根于我们的哲学发展史中,并且牢牢地控制了我们关于逻辑研究的理解,我们就能明白非形式逻辑这一理论努力是多么的困难和重要.我将首先澄清"演绎主义"的意思,然后再分别考察那些赞成和反对演绎主义的论证,最后,我将表明非形式逻辑是从演绎主义中挽救逻辑的理论尝试. 相似文献

In two experiments using a radial-arm maze, pairs of rats made choices among eight maze locations, each containing a large
quantity of one of two food types. The choices made by 1 rat affected the choices made by the other rat. Under most conditions,
visits by 1 rat increased the tendency of the other rat to subsequently choose that maze location. However, the effect depended
on the quality of the food available in a particular location. When it was possible for the rats to observe each other on
the maze arms and a rat had experienced that a location contained the less preferred food type, a previous visit to that location
by the foraging partner decreased the tendency to visit that location. These effects are attributed to working memory for
the spatial choices of another rat, and they indicate that memory produced by a rat’s own visit to a maze location is integrated
with memory for the behavior of another rat to determine spatial choice 相似文献
