A longitudinal study was conducted on 398 athletes and 369 nonathletes who were born before 1920 and attended Michigan State University. The subjects were compared to determine if intercollegiate athletic competition accounts for significant variation in longevity when considered with somatotype. Because some of the subjects were still alive at the time of the study, the BMDP Statistical Software was used to do a survival analysis with covariates. Preliminary comparisons considered the differences in somatotype between athletes and nonathletes. Two sample t-tests indicated that athletes were more mesomorphic and less ectomorphic (p less than .05) than nonathletes. When comparing the relationship between somatotype and longevity, the pooled data of athletes and nonathletes indicated that endomorphs were shorter lived than the other three comparison groups. When only the athletes were considered, similar results were found. However, the nonathlete group exhibited differences only between the mesomorphic and endomorphic groups. The endomorphs were shorter lived. Longevity was examined by using the Cox proportional hazards regression method with somatotype and athlete/nonathlete status as covariates. Somatotype, by itself, was found to be significantly related to longevity, (p less than .001). Athletic status was not significantly related to longevity, either by itself or when entered into the model with somatotype.  相似文献   

Predicting multicultural effectiveness of international students: the Multicultural Personality Questionnaire     

Jan Pieter Van Oudenhoven  Karen I. Van der Zee 《Int J Intercult Relat》2002,26(6)

The present study considered the reliability and validity of the 78-item revised version of the Multicultural Personality Questionnaire, a multidimensional instrument aimed at measuring multicultural effectiveness of expatriate employees and students. The questionnaire includes scales for cultural empathy, open-mindedness, emotional stability, social initiative and flexibility. Participants were native and foreign students of an international business school (N=171) in the Netherlands. The MPQ scales appeared to be more strongly predictive of adjustment of international students as compared to native students. Moreover, the instrument was able to explain variance in students’ adjustment beyond self-efficacy.  相似文献

The library's role in the continuing education of health professionals     

D D Van Vuren  R Adelson  R Caplan 《Bulletin of the Medical Library Association》1987,75(4):366-369

Health sciences librarians have historically viewed disseminating information to health professionals as a major role. Typically, they have provided individualized services and are among the professions that help health professionals further their education after finishing formal education. Another group directly involved in health professional continuing education is continuing education (CE) providers who offer ongoing learning through group activities. These two professions often reached the same audiences in the past, and their different approaches--individual and group--were complementary. Health professionals who needed information immediately or who wished individual learning used the library while those who wanted to hear eminent colleagues tended to use CE meetings or seminars; some did both. The librarians and CE providers rarely interacted, but this is now changing. With the introduction of personal computers, medical librarians have expanded their responsibilities to include formalized classroom instruction. At the same time, CE providers have increased their scope beyond formalized group instruction into individualized education. Librarians and CE providers can either collaborate and share their expertise or they can compete against each other.  相似文献

Client value models provide a framework for rational library planning (or, phrasing the answer in the form of a question)     

Van Moorsel G 《Medical reference services quarterly》2005,24(2):25-40

Libraries often do not know how clients value their product/ service offerings. Yet at a time when the mounting costs for library support are increasingly difficult to justify to the parent institution, the library's ability to gauge the value of its offerings to clients has never been more critical. Client Value Models (CVMs) establish a common definition of value elements-or a "value vocabulary"-for libraries and their clients, thereby providing a basis upon which to make rational planning decisions regarding product/service acquisition and development. The CVM concept is borrowed from business and industry, but its application has a natural fit in libraries. This article offers a theoretical consideration and practical illustration of CVM application in libraries.  相似文献   

A longitudinal evaluative study of student difficulties with engineering graphics   总被引：1，自引：1，他引：0  

Charles Potter  Errol Van Der Merwe  Wendy Kaufman  Julie Delacour 《European Journal of Engineering Education》2006,31(2):201-214

We have previously reported in this journal that spatial ability influences academic performance in engineering. We have also reported that spatial ability is trainable, and can be increased through instruction focused on using perception and mental imagery in three-dimensional representation. In this article, we present the results of a longitudinal evaluative study of student difficulties with engineering graphics at our university, involving research over a 24-year period. Prior to our intervention, the first-year engineering graphics course at our university had a failure rate of 36% for all engineering students, and failure rates of 80% for African students studying at our university. In terms of outcomes, our study indicates that changed teaching practices have been associated with increased pass rates, which currently average 88% for all students. There is clear evidence that African students no longer experience major difficulties in passing the course. This can be attributed both to changes in teaching methodology, as well as broader contextual changes occurring in South Africa over the period reviewed.

Despite evidence of increased pass rates, our data suggest that there is a continuing relationship between three-dimensional spatial perception and academic performance in engineering graphics, as well as with aggregated first-year engineering marks. For this reason, many students still require academic support. There is also evidence that female students experience difficulties with engineering graphics due to lack of previous technical experience, and use a variety of strategies to overcome their study problems. The most effective appear to be use of peers and friends, and in particular students who had previously taken the course, as mediators of the course content and materials. Those female students who have not taken technical drawing at school level, and female students who do not network with other engineering students, are those at greatest disadvantage.  相似文献   

Cognitive Aging and Computer-Based Instructional Design: Where Do We Go From Here?   总被引：1，自引：0，他引：1  

Pascal W. M. Van Gerven  Fred Paas  Huib K. Tabbers 《Educational Psychology Review》2006,18(2):141-157

In this article, themost relevant literature on cognitive aging and instructional design is merged to formulate recommendations for designing computer-based training material aimed at elderly learners. The core message is that researchers and instructional designers do not need to develop special computerized instruction for older adults. Rather, existing principles of general instructional and multimedia design can be evaluated and used to accommodate the needs of elderly learners. Particular attention is given to John Sweller’s Cognitive Load Theory (CLT) and Richard Mayer’s Cognitive Theory of Multimedia Learning (CTML). It is argued that these instructional theories bear important benefits for older learners because they support an efficient use of available cognitive resources. New research directions are suggested to test the implications of these theories for learning in old age.

A System of Student Feedback: Considerations of Academic Staff Taken into Account     

Veerle Hulpiau  Evelien Masschelein  Luc Van Der Stockt  Piet Verhesschen  Kim Waeytens 《Tertiary Education and Management》2013,19(1):35-45

As a consequence of the suspension of a system of yearly evaluations of individual courses with student questionnaires, the University of Leuven organised a broad consultation of the academic community focussing on what they expect from a system based on student feedback. The study revealed that this community attaches great importance to a clear definition of the goals of student feedback, improvement and accountability, and a logical translation of these goals into a concrete approach. The study also confirmed the need of academic staff for a concrete response to the importance they give to quality improvement and enhancement besides accountability.  相似文献
