ITV Programmes for Schools: any future?     

J. Weltman 《Learning, Media and Technology》1991,17(1):5-14

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 of knowledge of results effects during motor skill acquisition     

J R Blackwell  R W Simmons  J A Spray 《Research quarterly for exercise and sport》1991,62(1):10-17

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 standards work: the next frontier     

Tseng SC  Arcand JL  Brugger JM  Finn M  Olson AJ  Somers S 《Library resources & technical services》1990,34(2):139-157

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   

Risk management information for HIV infection     

Edwards AJ 《Medical reference services quarterly》1990,9(4):27-42

This article discusses HIV infection in terms of the risk manager's information needs in the health care environment. The malpractice problem, increasing workman's compensation suits, the greater role of the ombudsman, implementation of the National Practitioner Data Bank, and the Joint Commission on Accreditation of Health Care Organizations' (JCAHO) emphasis on clinical excellence are conditions which have given greater importance to the risk manager's position. Included in this article are hedges to retrieve various components of risk management and a select bibliography from AIDSLINE.  相似文献

Hans-Jürgen Siegert 《Informatik - Forschung und Entwicklung》2008,22(4):237-266

Zusammenfassung  Zusammen mit drei weiteren Artikeln, die den übergang vom Batch- zum Timesharing-Betrieb, das Unternehmen und die Hardware des TR440 beschreiben, gibt dieser Text einen Rückblick auf Entwicklung und Realisierung des deutschen Gro?rechners TR440 bei AEG-Telefunken und den Nachfolgefirmen. Dieser Teil des Rückblicks besch?ftigt sich mit der Software und der Software-Entwicklung für den TR440, insbesondere in den Jahren 1965 bis 1974. Es werden technische Highlights der Software behandelt und Einblicke in die Software-Entwicklung selbst gegeben, insbesondere auch Hintergrundinformationen zu Einflüssen, Verantwortungen und Entscheidungen. Der Artikel beginnt mit dem TR4, dem Vorg?nger des TR440, und endet mit den Aktivit?ten für einen TR440-Nachfolger. CR subject classification  K.1 ; K.2 ; K.6 ; D.2 ; D.3 ; D.4 ; D.2.9  相似文献
