The design and testing of a wire velocimeter     

J Witters  G Heremans  W Bohets  V Stijnen  H Van Coppenolle 《Journal of sports sciences》1985,3(3):197-206

The basic principles underlying the design of a velocimeter based on an unwinding wire, for use in athletics research, are discussed. It is shown by theoretical analysis that, in order to avoid runaway effects, the tension on the wire should be either high or low but not of intermediate strength. The low tension regime is shown to be theoretically the most favourable as it combines high accuracy of speed measurements in decelerated motion with insensitivity to resonance oscillations of the wire. Practical considerations concerning the ruggedness of the apparatus, however, favour the high tension regime. A modern apparatus incorporating microprocessors and working with thin nylon wire stretched by a force of the order of 1 N, i.e. in the high tension regime, has been constructed and tested. The test results show that the velocity of decelerated motions (up to decelerations of the order of 10 m s-2) can be faithfully recorded in the velocity range 0-15 m s-1. The relative error for the measurement of constant speed up to 15 m s-1 is about one in a thousand, which is very small and practically unattainable by other methods. An application to the study of the long jump is demonstrated and validated by the use of film analysis.  相似文献

ACOGQUEST: the model phase of the IAIMS project of the American College of Obstetricians and Gynecologists.     

K M DeGeorges  P Van Hine  W H Pearse 《Bulletin of the Medical Library Association》1992,80(3):276-280

In 1990, the American College of Obstetricians and Gynecologists (ACOG) became the first national organization to receive a model phase Integrated Academic Information Management System (IAIMS) grant from the National Library of Medicine. The goal of the ACOG model phase project is to develop and test a prototype for an integrated system that will meet the needs of ACOG and NAACOG members in patient care, research, education, and administrative information. The model phase goal will be accomplished primarily through ACOGQUEST, an integrated approach to providing accurate, current, quality-filtered information to ACOG and NAACOG members in a variety of formats. Another method of information dissemination now being tested is a heuristic-based patient management database, which will include a concise, interactive display of ACOG-reviewed information that can be incorporated into patient records.  相似文献

Problematical aspects of expatriate educational research with and in developing countries     

Wout Van Den Bor 《International Journal of Educational Development》1985,5(3):167-181

Discussions of the problems of expatriate educational research with and in developing countries are at the core of this paper. How should a research project be set up? Who should initiate it and finance it? How does it fit into an overall development strategy? These and other questions are analysed sensitively and with understanding. The paper also examines how research questions should be formulated and how the research should be designed. Inevitably there are hidden objectives which do not appear explicit in the early stages. There are yet others which should be made explicit. Problems also arise over collecting and disseminating data, especially when the time comes to publish a report. So often political and other considerations influence the final report. Ultimately, however, the success or failure and the value or otherwise of any research depends on an intricate web of relationships, at the heart of which must be mutual trust.  相似文献   

The underarm throw for accuracy in children     

J H Van Rossum  R J Bootsma 《Journal of sports sciences》1989,7(2):101-112

Forty boys and girls of two age groups (mean ages 52 and 70 months, respectively) performed 35 trials on a throwing task demanding accuracy. As might be expected, the older children were significantly more accurate than the younger ones but there were no sex differences. Film analysis of the throws showed that, although both age groups attempted to employ the adult strategy of varying velocity while keeping ball-release angle constant, the younger group was less successful in the latter aspect. The manner in which consistent release angles were arrived at by the older group was through the use of a movement pattern in which the elbow angle did not change during the forward swing. Such a movement pattern appeared less frequently in the younger age group. The results of this study provide support for a mode of research identifying functionally relevant kinematic variables that can subsequently be shown to follow from distinctive execution categories. In such a way, changes in outcome measures with increasing age and/or skill level can be functionally understood and identified.  相似文献   

Getting started with electronic mail     

D D Van Vuren  D E Johnson 《Bulletin of the Medical Library Association》1985,73(3):267-270

This paper gives suggestions to librarians on how to get started with electronic mail. It discusses the cost- and time-saving advantages of using electronic mail rather than TWX, United States mail, or telephones for communicating ILL requests and messages. For instance, preliminary cost data show that electronic mail is often half as expensive as TWX and costs no more than a 22 stamp. Key management concerns that must be considered when setting up electronic mail are discussed, including the need for subscribers to agree on one system. Also covered are the types of equipment that can be used with electronic mail, including print terminals.  相似文献   

Negative incentive steering in a policy network     

Frans A. Van Vught 《Higher Education》1985,14(6):593-616

In this article the process of developing a policy for the recent comprehensive retrenchment operation in the Dutch university system is analysed from a theoretical point of view on decisionmaking. The article especially addresses the question whether some empirical evidence can be found for the rationalist view of collective decision-making, which states that a process of social communication should eventually lead to a unanimous and rational consensus concerning the selection of the optimal policy.The actual analysis concerns the way a retrenchment policy has been developed in a process of social communication between the most important actors: the Minister of Education and Science and the thirteen Dutch universities. It is assumed that the various communicative linkages between these actors can be interpreted as a policy network in which both governmental and non-governmental actors operate.The article concludes that in the Dutch university policy-network a complicated balance of interdependencies exists and that several sub-networks can be distinguished. It is also concluded that the Minister, while recognizing the interdependencies in the network, was able to use a special kind of (negative) incentive, inducing the universities to act as he wished.This negative incentive steering, however, also persuaded the universities to go to the utmost in their consultation efforts, thus trying to reach the rationalist ideal of collective decision-making. The final conclusion therefore is that the rationalist view of collective decision-making does not appear to be unrealistic. The article ends with a warning against a common mistake made regarding the normative appearance of the rationalist perspective.The case of the policy development process concerning the retrenchment operation in the Dutch university system in 1982 and 1983.  相似文献
