The purpose of the present study was to determine the value of DRL schedules in reducing the behavior of a group of behaviorally disordered children. During the DRL procedure, reinforcement was made available for inappropriate language that was less than a prescribed limit for each day. When the DRL limit was successively decreased across weeks, the behavior of the students systematically decreased. Data indicated that reinforcing low rates of behavior may be an effective alternative to the use of aversive contingencies to reduce the misbehavior of such children. 相似文献

The purpose of this study is to review 10 NCES databases that can be used for researching postsecondary issues and provide lesser‐known facts to using the datasets that are important but may not be widely understood. Issues addressed include: (1) access; (2) statistical issues; (3) database nuances; and (4) database training opportunities. A concise review of each database is also provided which includes: (1) a general overview of the survey; (2) formats in which the dataset is available; and (3) research areas (which include key variables that can be used as a basis for research themes along with examples of how the dataset has been used to answer research questions). The databases provide rich sources of information for national as well as international comparative analysis studies. 相似文献

This article is the third in a series in this regular feature. The intention of the series is to look at important global developments in health science libraries. These articles will serve as a road map, describing the key changes in the field and exploring factors driving these changes. The present article by the current president of the Medical Library Association outlines two important developments in the United States. The topics chosen for consideration are national initiatives in the United States impacting health sciences libraries and librarians and enhanced roles for U.S. health sciences librarians in providing support for research.

Marrying the psychometric paradigm with the community structure theory, this paper examines the coverage of a superbug (NDM-1) in newspapers in India, the UK, and the USA. It identifies several community structure characteristics: level of vested economic interest, level of health care available, and size of health care stakeholders as factors influencing how risks of NDM-1 are portrayed in terms of the level of dread, controllability, familiarity, and uncertainty. The finding provides baseline data for the scientific community and public health professionals in creating more effective messages to inform the public about the risks of superbugs. 相似文献
