The successful delivery of health care involves a commitment to improved communication both with regard to health professionals and the public. The need for innovative educational patterns is implicit in the recommendations of the latest Carnegie Commission Report, Higher Education and the Nation's Health.The new technology of videorecording permits the learner to learn at a time and place of his own choosing. Information is transmitted through the cathode ray tube-a television set-the medium of our time. The videorecord is of significant value in the basic and clinical sciences, in training personnel for allied health professions, and in continuing education. It is thoroughly compatible with the new concept of the open university, an institution without walls.In addition to its unquestioned value in educational programs in the health sciences, the videorecord has major implications for the curriculum in librarianship and for increasing the professional competence of medical librarians and their ancillaries. The medical librarian has a major stake in its imaginative use for overcoming some of the barriers to individual and community health. 相似文献

Science Citation Index is one of a number of indexes based on the assumption that the papers cited by one author refer to work which is relevant to the subject discussed by the author citing them. Cleverdon, however, has questioned that assumption, and it was to test the assumption that this research was undertaken. An attempt was made to determine what percent of articles cited were related to the citing article. The conclusion reached was that in the field of medicine approximately 72 percent of the cited papers were considered related to the original paper by the authors of the original, thus apparently bearing out the assumption for citation indexing. 相似文献

The immediate circumstances of the new Broadcasting Act are discussed. The impact of this legislation on schools broadcasting is then considered in relation to the history of earlier legislation in the UK, and the early responses to the Television Act of 1954. The importance of the personnel involved in television production and their commitment to the values of public service is stressed, and placed against the gloomier forebodings of the pessimists of the past‐‐and of today. The article concludes with the assertion that it is the people in the television industry itself, and the values they hold, that will ensure the continued survival of good schools television. 相似文献

Time series analysis was used to investigate the hypothesis that during acquisition of a motor skill, knowledge of results (KR) information is used to generate a stable internal referent about which response errors are randomly distributed. Sixteen subjects completed 50 acquisition trials of each of three movements whose spatial-temporal characteristics differed. Acquisition trials were either blocked, with each movement being presented in series, or randomized, with the presentation of movements occurring in random order. Analysis of movement time data indicated the contextual interference effect reported in previous studies was replicated in the present experiment. Time series analysis of the acquisition trial data revealed the majority of individual subject response patterns during blocked trials were best described by a model with a temporarily stationary, internal reference of the criterion and systematic, trial-to-trial variation of response errors. During random trial conditions, response patterns were usually best described by a "White-noise" model. This model predicts a permanently stationary, internal reference associated with randomly distributed response errors that are unaffected by KR information. These results are not consistent with previous work using time series analysis to describe motor behavior (Spray & Newell, 1986). 相似文献

Serials, one of the more complicated areas of library technical endeavors, has lacked the benefit of standards for a long time. Even now, with standards beginning to be available, the majority of institutions are not working within standard serials formats. A survey to determine the use of serials standards in libraries was conducted in 1988 by the American Library Association, Resources and Technical Services Division, Serials Section, Committee to Study Serials Standards. In the spring of 1988 a survey was sent to a group encompassing the Association of Research Libraries members, CONSER participants, United States Newspaper Program participants, Microform Project libraries, and some vendors and librarians who attended the Committee meetings on a regular basis. The survey questionnaire assessed the current level of serials standards awareness of librarians and vendors. Topics included the type of serials systems used, standards relevant to serials control and union listing and whether or not they are implemented, types and levels of training staff received in the application of standards, benefits of the standards, and areas where standards are most needed. 相似文献
