This study used data from the Head Start Family and Child Experiences Survey (FACES) 2009 4-year-old cohort to examine associations among family characteristics, home and classroom environments, and the emergent literacy skills of Head Start children. Results from hierarchical linear models suggest that both family and classroom contexts play a unique and interactive role in supporting Head Start children's development of different sets of emergent literacy skills. Parental warmth was positively related to children's oral language skills (i.e., receptive and expressive vocabulary knowledge), and teachers' educational level and the quality of instructional support in the classroom were significantly associated with children's code-related skills (i.e., letter-name and letter-sound knowledge). Further, high-quality instructional support in the classroom buffered the negative influence of low maternal education on children's oral language skills. Interventions focusing on enhancing the quality of parent-child interactions, in addition to professional development for teachers designed to improve the quality of instructional support, may contribute to promoting the development of emergent literacy skills of young children from low-income families. 相似文献

This study examines the experiences of nonnative English-speaking faculty instructors teaching subject courses in English-medium instruction (EMI) at a Korean university and reveals the perceived roles of the local language in the context. The data consist of questionnaire responses of 91 Korean professors and qualitative interviews with 15 who had answered the questionnaires. Findings showed that the participants perceived the local students’ performances and the amount of interaction between local and international students negatively. Their perceived need for the local, Korean language correlated negatively with the interaction between Korean and international students. In the qualitative interviews, the local language in the EMI context, despite the full-fledged EMI policy being implemented top down, was represented as crucial for social and instructional purposes and for their own time management. These perceived roles were found to be associated with their multiple identities, as instructors and researchers, required and practiced in the context. The findings are discussed to provide information on how to support an EMI policy for internationalization of higher education, especially in non-English-speaking societies. 相似文献

The current study was designed to investigate how the quality of stimulation and support available to children in the home interacts with participation in Early Head Start to determine children's development. Data were obtained as part of the national evaluation of Early Head Start (EHSRE), a randomized trial involving 3,001 children and families from 17 program sites. Hierarchical linear regression analyses were used to examine the interaction of EHS with (a) early maternal emotional warmth and (b) provision of a stimulating home environment on children's development at ages 3 and 5. Findings showed EHS sometimes differentially benefited children who came from households where the levels of warmth and stimulation were lowest. However, there was evidence of other forms of moderation as well. 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.

Medic and colleagues (Medic, Starkes, & Young, 2007) found that relatively younger cohorts of Masters athletes had higher participation rates and achieved higher performances compared with a relatively older cohort. Considering that Medic and colleagues' (2007) study was cross-sectional in nature, the purpose of this investigation was to employ a retrospective longitudinal study design to examine the participation rates of Masters swimmers as a function of an individual's constituent year within any 5-year age category over a period of 6 years. Using archived data from the 2003 to 2009 US Masters Short Course National Championships, swimmers' attendance was followed for a period of six consecutive years. Results indicated that a participation-related relative age effect was observed among swimmers who, over a period of 6 years, competed in either at least one championship (N = 2596; Cochran's Q? = 64.16, r(s) = -0.92, both P < 0.0001) or at least three championships (N = 441; Cochran's Q? = 47.51, r(s) = -0.91, both P < 0.0001). Overall, effect size analyses indicated that the odds of a Masters swimmer participating in the championship during the first constituent year of any 5-year age category was more than two times greater than the odds of that athlete participating during the fifth constituent year. 相似文献

Our study explored the contribution of gender role stress (GRS) and sociocultural appearance demands to symptoms of muscle dysmorphia (MD) in a college sample of 219 women and 154 men. For women, five GRS subscales, sociocultural appearance demands, age, and frequency of aerobic exercise predicted MD symptoms (model R2 = .33; F(8,210) = 12.81, p < . 001); for men, only one GRS subscale, age, and sociocultural appearance demands predicted MD symptoms (model R2 = .40; F(3,150) = 9.52, p < .001). Post hoc analyses revealed that a small number of items explained a substantial portion of the variation, suggesting that MD may be more related to specific perceptions of pressure to attain an attractive body than to global gender role stress. 相似文献
