Online data bases might be more valuable to users if their structures more closely matched those of the disciplines represented by the data bases. To explore this concept, a structure for the field of tropical medicine was derived from the interrelationships of signs and symptoms of 37 tropical diseases. A similar structure was derived for the interrelationships of sign and symptom index terms applied to articles on these topical diseases in the MEDLINE data base. The poor correlation of the two structures led to the suggestion that rigorous indexing of articles with sign and symptom index terms or check tags would enhance the usefulness of the data base. Similar studies could be envisioned for other disciplines and data bases.  相似文献

Over the past decade, education reform and teacher training projects have spent a great deal of effort to create and support sustainable, scalable online communities of education professionals. For the most part, those communities have been created in isolation from the existing local professional communities within which the teachers practice. We argue that focusing on online technology solely as a mechanism to deliver training and/or create online networks places the cart before the horse by ignoring the Internet's even greater potential to help support and strengthen local communities of practice within which teachers work. In this article we seek guideposts to help education technologists understand the nature of local K-12 education communities of practice--specifically their reciprocal relationship with teacher professional development and instructional improvement interventions--as a prerequisite to designing online sociotechnical infrastructure that supports the professional growth of education professionals.  相似文献

Abstract

From its beginnings, the Program for Cooperative Cataloging (PCC) has been an international leader of change in bibliographic and authority control and maintenance, and metadata creation and distribution. This article highlights some PCC achievements in these areas.  相似文献

Community-based health and human services professionals can play an important role in bolstering wellness through offering education to elderly residents and healthcare providers on how to address the unique needs of this population. The purpose of this study was to examine the healthcare needs of the elderly living in two metropolitan counties in Georgia that have experienced an increase in the number of elderly residents. Utilizing qualitative data garnered through focus groups, two main themes were identified: the role of exercise as a means of personal power and feelings of powerlessness. Participants’ narratives reflected opportunities and situations fostering good health through exerting their personal power to alter or improve individual health. On the other hand, negative pathways leading away from optimal health were realized when participants felt powerless to change their health status. For health and human services professionals working with the elderly, these findings should be considered as population, personal well-being, and power changes overtime.  相似文献

Depressive symptomatology was assessed in a sample of 246 male juvenile sex offenders using the Beck Depression Inventory. Of these participants, the racial composition was black = 147, Hispanic = 62, Caucasian = 34. Three adolescents elected not to identify their racial origin. Subjects were divided according to their self-reports of having been sexually or physically abused. The mean Beck score across all subjects was 14.3, a value markedly higher than published norms and indicative of mild depression. Forty-two percent of subjects attained scores indicative of appreciable depressive symptomatology. A history of sexual or physical abuse was significantly related to high Beck scores; abused subjects had a mean Beck score of 16.4, as contrasted to 12.3 for nonabused subjects (Wilcoxon test: z = 2.82; p less than .005). This relationship was apparent across all racial groups. While Hispanic subjects tended to have higher Beck scores and Caucasians lower scores, racial differences were not statistically significant. Results indicate that juveniles who have committed sexual crimes, particularly those with a history of abuse, should be evaluated for depression.  相似文献

In the past 20 years, the landscape of Higher Education in the United Kingdom has changed considerably. With the prospect of tuition fees spiralling above £9,000 per year, per student, it is important to explore the impact this has upon the student experience. In spite of the vast financial investment current students make towards their education, student attendance and engagement remain low. The present study therefore adopted a qualitative approach using focus groups to explore reasons for non-attendance at university teaching sessions. Four key themes emerged; these surrounded issues about a sense of belonging to university, views of the teaching (material taught and the personality and method of the tutor), perceptions of being a consumer and external pressures. This research suggests that universities should pay particular attention to the reasons why students do not attend and possibly change practice, providing more support where appropriate.  相似文献

This paper reports a research project developed in partnership with the Principal and Leadership Team of an Australian secondary school. It monitored a school-based initiative designed to address the underachievement of male students. Students in Year 9 selected single-gender or coeducational classes in mathematics and English during the second half of a school year. Student scores in standardized tests and school-based assessment in these subjects were obtained before and after the establishment of the initiative. Results indicate no significant difference in mathematics achievement that can be attributed to gender or class composition. However, scores in school-based English improved for students in single-gender classes. Improvement for girls in single-gender classes was greater than that for boys in single-gender classes.  相似文献
