Among the factors which will influence the emerging roles of medical libraries will be the changing needs of the medical scholars who use them. The effectiveness of the medical practitioner will be determined to an increasing extent by his capacity to mobilize information with a rapidity sufficient to permit its application in day-to-day decision-making. The practice of medicine is becoming an increasingly academic pursuit. The library and the librarian will, therefore, become more directly involved in the practice of medicine, and the library will be a more crucial resource in providing superior patient-care. Changes in undergraduate and continuing medical education will make new demands on the library. These and other related developments will create new functions, new problems, and new opportunities for the librarian.  相似文献

ABSTRACT

The Deep Dive into KBART preconference workshop provided a comprehensive overview of the National Information Standards Organization Knowledge Bases and Related Tools (KBART) Phase II Recommended Practice (http://www.niso.org/publications/rp/rp-9–2014/). The workshop was divided into four sections. The first provided an overview of the background, purpose, and value of KBART to all members of the information supply chain. The next section focused on the basic guidelines for effective exchange of metadata with knowledgebases, including method of exchange, data format, file naming conventions, and frequency of exchange. The remaining two sections of the workshop addressed the correct use of KBART data fields, first in relation to serials and then to monographs. Through classroom instruction, interactive quizzes, and hands-on exercises, the workshop provided in-depth coverage of all KBART data elements, with special focus on many of the most frequently asked questions about the recommended practice.  相似文献

社会规范学习是个体品德形成的基础。由于忽视了社会规范学习的特点,社会规范学习成了令人厌烦的灌输与说教。内隐学习理论对社会规范学习的启示在于:社会规范学习中,必须激发学生内隐学习潜能;在各个学科教学中,渗透积极人生观;个体在无意识中形成内在品质;以外显可量化行为间接考察内隐的观念。在社会规范学习中运用内隐学习理论应注意:正确处理社会规范学习中内隐学习和外显学习的关系;选用符合学生认知发展规律的内隐学习材料;懂得内隐学习不是一蹴而就的。  相似文献

This study investigated the construction and evaluation of an instrument called the Perceptions of Success Inventory for Beginning Teachers (PSI-BT) intended to measure factors documented in research that contribute to beginning teachers’ perceptions of success. The PSI-BT was found to assess the following factors using exploratory factor analysis: (1) Administrative Support, (2) Classroom Climate, (3) Mentor Support, (4) Colleague and Instructional Resource Support, (5) Commitment, and (6) Assignment and Workload. Internal reliability, content validity, and concurrent validity were also measured in the validation process. Our findings suggest that the PSI-BT provides a reliable and valid instrument that can provide schools with valuable feedback to ensure the success of their beginning teachers.  相似文献

This study tested the degree to which the uncertainty management process that emerging adults go through following an adverse event predicts their perceptions of posttraumatic growth. Participants included 215 emerging adults who had experienced an adverse life event within the past year. Overall, the results largely supported the theory of motivated information management, as uncertainty discrepancies positively predicted negative emotions about the adverse event, which in turn predicted outcome expectancies, but not efficacy assessments. Outcome expectancies were predictive of efficacy assessments, which in turn were predictive of a willingness to seek information about the event from a parent. Collectively, uncertainty management behaviors predicted posttraumatic growth and included significant indirect effects for uncertainty discrepancies through communication and target efficacy, respectively.  相似文献

PURPOSE: Chest radiographs (CXR) are the standard method for evaluating rib fractures in abused infants. Computed tomography (CT) is a sensitive method to detect rib fractures. The purpose of this study was to compare CT and CXR in the evaluation of rib fractures in abused infants. METHODS: This retrospective study included all 12 abused infants identified from 1999 to 2004 who had rib fractures and both CXR and CT (8 abdomen CTs, 4 chest CTs). CT exams had been performed for clinical indications, and were obtained within one day of the CXR. Studies were reviewed by two pediatric radiologists to determine the number, locations, and approximate ages of the rib fractures. A total of 225 ribs were completely (192) or partially (33) seen by CT, and the matched ribs on CXR were used for the analysis. RESULTS: The mean patient age was 2.5 months (1.2-5.6), with seven females and five males. While 131 fractures were visualized by CT, only 79 were seen by CXR (p<.001). One patient had fractures only seen by CT. There were significantly (p<.05) more early subacute (24 vs. 4), subacute (47 vs. 26), and old fractures (4 vs. 0) seen by CT than by CXR. Anterior (42 vs. 11), anterolateral (21 vs. 12), posterolateral (9 vs. 3) and posterior (39 vs. 24) fractures were better seen by CT than by CXR (p<.01). Bilateral fractures were detected more often by CT (11) than by CXR (6). CONCLUSIONS: While this study group is small, these findings suggest that CT is better than CXR in visualizing rib fractures in abused infants.  相似文献
