The current mission statement of the Medical Library Association states that it is "dedicated to improving health through professional excellence and leadership of its members in the ... provision of information services and educational programs ..." With this goal in mind, retractions offer medical librarians a professional challenge to become involved in the scientific process. Through results of a survey conducted among the consortium of South Central Academic Medical Libraries (SCAMeL), this paper reveals opinions on the importance of retraction awareness and who is responsible for disseminating this knowledge. The paper also reports what the Louisiana State University Medical Center at Shreveport Library and other SCAMeL member libraries are doing to promote awareness. 相似文献

Genetics is an area of science that causes problems for children. This paper reviews initial findings from research into children's
views of how inheritance works and the role this plays in their overall view of genetics. The implications these results have
for the traditional approach to genetics education are outlined. An alternative approach is proposed.
Specializations: teacher development, science and technology curriculum development. 相似文献

ABSTRACTThis study sought to provide a framework for evaluating machine score-ability of items using a new score-ability rating scale, and to determine the extent to which ratings were predictive of observed automated scoring performance. The study listed and described a set of factors that are thought to influence machine score-ability; these factors informed the score-ability rating applied by expert raters. Five Reading items, six Science items, and 10 Math items were examined. Experts in automated scoring served as reviewers, providing independent ratings of score-ability before engine calibration. Following the rating, engines were calibrated and their performances were evaluated using common industry criteria. Three derived criteria from the engine evaluations were computed: the score-ability value in the rating scale based on the empirical results, the number of industry evaluation criteria met by the engine, the approval status of the engine based on the number of criteria met. The results indicated that the score-ability ratings were moderately correlated with Science score-ability, the ratings were weakly correlated with Math score-ability, and were not correlated with Reading score-ability. 相似文献

Statistical analysis and comparison of library print and online holdings are used to reduce shelf area and inform index back-file purchases. Nikki DeMoville of California Polytechnic State University’s Robert E. Kennedy Library combined Counting Online Usage of Networked Electronic Resources (COUNTER) JR2 Access Denied usage reports, holdings information, and print circulation data to identify journals exhibiting a high desirability for online access and low print circulation. In this presentation, DeMoville shared how further combination of this data with ScienceDirect quote lists for back-file journal packages and Web of Science metrics could be used to support the efficient de-selection of print journals, allowing the library to recover the maximum amount of physical space while also acquiring backfile access to those titles most frequently needed in electronic format. The presentation detailed the workflows and comparative methodology used to reach collection management and development decisions for journal coverage, with an emphasis on before and after metrics. 相似文献

OBJECTIVE: The primary objective was to examine the long-term impact of mother-son incest and positive initial perceptions of sexual abuse experiences on adult male psychosocial functioning. METHOD: Sixty-seven clinic-referred men with a history of sexual abuse participated. The participants completed self-report measures regarding their current psychosocial functioning and described the nature of their sexual and physical abuse experiences during childhood. RESULTS: Seventeen men reported mother-son incest, and these men endorsed more trauma symptoms than did other sexually abused men, even after controlling for a history of multiple perpetrators and physical abuse. Mother-son incest was likely to be subtle, involving behaviors that may be difficult to distinguish from normal caregiving (e.g., genital touching), despite the potentially serious long-term consequences. Twenty-seven men recalled positive or mixed initial perceptions of the abuse, including about half of the men who had been abused by their mothers. These men reported more adjustment problems than did men who recalled purely negative initial perceptions. CONCLUSIONS: Mother-son incest and positive initial perceptions of sexual abuse experiences both appear to be risk factors for more severe psychosocial adjustment problems among clinic-referred men. 相似文献

A modified system of least intrusive prompting was used to teach middle school students with moderate intellectual disability who were emergent readers to comprehend short passages of text. Text passages were summaries of the chapters of age-appropriate novels rewritten for a beginning reading level. Time delay was used to teach the participants to pair WH words to their definition. A modified system of least intrusive prompting was used to teach strategies for answering comprehension questions. All participants improved the number of correct responses for both rules definitions and comprehension responses from baseline to intervention. Additionally, probes collected during the session prior to the introduction of a new book indicated comprehension skills generalized to new untaught books. 相似文献
