Much of the existing literature on student engagement focuses on what happens within the higher education environment or what the institution has direct control over, restricting understanding of how issues outside of the institution affect engagement. This paper argues that efforts to improve student engagement should be broadened to incorporate issues relating to the family. It employed a case study design in order to develop a broad and more in-depth understanding of how family influences the amount of time and effort students invest in their learning in a large public university in Ghana. It was established that engagement is influenced by family expectation, financial and social support, as well as monitoring of students’ academic performance. The unique contribution of the study is that it broadens current understandings of engagement because it adds an aspect that has not been highlighted in current work on engagement, making a case for institutions to work more with families to get a broader understanding of challenges students face in order to provide comprehensive support. 相似文献

Both classical and contemporary interpersonal theories have identified the social networks surrounding a couple as integral players in relational development and maintenance. The current project extends this line of research by designing (Study 1) and implementing (Study 2) a measurement of social network interdependence. Scales of network interference and facilitation are developed and probed using exploratory and confirmatory factor analysis. Results support distinct measures of network interference and facilitation. Invariance between differencing samples is tested for using multi-factor CFA. Results showed that measures of network interference and facilitation significantly vary between married and dating couples. Finally, convergent, divergent, and concurrent validity is tested for subscales using variables in relational turbulence theory. Results demonstrate that network interference and facilitation uniquely impact outcome variables above and beyond experiences of partner interference and facilitation. Results are discussed in terms of theory development. 相似文献

Objective:
The objective of this study was to validate an assessment instrument for MEDLINE search strategies at an academic medical center.Method:
Two approaches were used to investigate if the search assessment tool could capture performance differences in search strategy construction. First, data from an evaluation of MEDLINE searches from a pediatric resident''s longitudinal assessment were investigated. Second, a cross-section of search strategies from residents in one incoming class was compared with strategies of residents graduating a year later. MEDLINE search strategies formulated by faculty who had been identified as having search expertise were used as a gold standard comparison. Participants were presented with a clinical scenario and asked to identify the search question and conduct a MEDLINE search. Two librarians rated the blinded search strategies.Results:
Search strategy scores were significantly higher for residents who received training than the comparison group with no training. There was no significant difference in search strategy scores between senior residents who received training and faculty experts.Conclusion:
The results provide evidence for the validity of the instrument to evaluate MEDLINE search strategies. This assessment tool can measure improvements in information-seeking skills and provide data to fulfill Accreditation Council for Graduate Medical Education competencies.Highlights
- The University of Michigan MEDLINE Search Assessment tool can be used to assess search skills in residency education.
- Five elements were identified as critical elements in the development of an effective MEDLINE search strategy: inclusion of all search concepts, appropriate use of Medical Subject Headings, appropriate use of search limits, successful combination of all concepts, and search efficiency.
Implications
- This validated assessment tool can serve as an effective means to measure improvements in residents'' information-seeking skills and provide data to fulfill Accreditation Council for Graduate Medical Education competencies.

The public's growing interest in health information and the health professions' increasing need to locate health education materials can be answered in part by the new Combined Health Information Database (CHID). This unique database focuses on materials and programs in professional and patient education, general health education, and community risk reduction. Accessible through BRS, CHID suggests sources for procuring brochures, pamphlets, articles, and films on community services, programs at HMOs and hospitals, aspects of coping, and more. CHID is a joint project of six federally funded agencies in the Public Health Service. CHID provides citations with abstracts to major health journals, books, reports, pamphlets, hard-to-find information resources, and to health education programs under way in state and local health departments and other locations. 相似文献
