Objective:A growing volume of studies address methods for performing systematic reviews of qualitative studies. One such methodological aspect is the conceptual framework used to structure the review question and plan the search strategy for locating relevant studies. The purpose of this case study was to evaluate the retrieval potential of each element of conceptual frameworks in qualitative systematic reviews in the health sciences.Methods:The presence of elements from conceptual frameworks in publication titles, abstracts, and controlled vocabulary in CINAHL and PubMed was analyzed using a set of qualitative reviews and their included studies as a gold standard. Using a sample of 101 publications, we determined whether particular publications could be retrieved if a specific element from the conceptual framework was used in the search strategy.Results:We found that the relative recall of conceptual framework elements varied considerably, with higher recall for patient/population (99%) and research type (97%) and lower recall for intervention/phenomenon of interest (74%), outcome (79%), and context (61%).Conclusion:The use of patient/population and research type elements had high relative recall for qualitative studies. However, other elements should be used with great care due to lower relative recall. 相似文献

An unexpected and remarkable preference for second language reading among some dyslexics has been noted, presenting a challenge to accepted theory on dyslexia and the capacity for second language learning. The current study was designed to examine this phenomenon by systematically looking at the differential reading scores in the first and second languages of reading-disabled young Swedish adults who claimed to prefer reading in their second language (English). Three groups were selected for study: a group of 10 reading-disabled young adults who prefer to read English; a second group of 10 reading-disabled with no special preference for second language reading, matched on word recognition efficiency, age group, gender and educational level and a group of 10 normal readers matched on age group and educational level. The test battery was designed to compare overall reading efficiency in English and Swedish and therefore encompassed both speed and accuracy measures. The battery covered seven phonological measures, four orthographic measures,three isolated word reading measures, two continuous text reading measures, a comprehension task and an author recognition task. All tasks were carried out in both English and Swedish. The results showed that two dyslexic groups differed significantly in the degree to which task performance, including reading efficiency, was impeded by the English format. A tentative hypothesis was forwarded as to how the exceptional and unexpected facility with English might be explained. 相似文献

This study tested implications of new genetic discoveries for understanding the association between parental investment and children’s educational attainment. A novel design matched genetic data from 860 British mothers and their children with home-visit measures of parenting: the E-Risk Study. Three findings emerged. First, both mothers’ and children’s education-associated genetics, summarized in a genome-wide polygenic score, were associated with parenting—a gene–environment correlation. Second, accounting for genetic influences slightly reduced associations between parenting and children’s attainment—indicating some genetic confounding. Third, mothers’ genetics were associated with children’s attainment over and above children's own genetics, via cognitively stimulating parenting—an environmentally mediated effect. Findings imply that, when interpreting parents’ effects on children, environmentalists must consider genetic transmission, but geneticists must also consider environmental transmission. 相似文献

After living outside Japan for one to ten years, the college students I interviewed reflected on how they have been transformed. Some transformations are short-lived physical changes in hair and clothing; some are visible behavioral changes in how they walk or move their arms or faces. The more serious changes are in interpersonal styles and expressions, changes that make them seem “un-Japanese.” The returnees are ambivalent about the latter changes; they recognize the problems but they are reluctant to suppress or give up entirely the newly acquired aspects of themselves. 相似文献

This article offers an overview and analysis of recent early childhood education reforms in Great Britain. It examines the
national mandates to grant Universal Preschool Education to all three and four year olds as well as recent strides to provide
for infants and toddlers in model centers throughout the country. Attention is given to British practices and policies, research
findings and international implications. 相似文献
