Regional health library service in northern Ireland     

D S Crawford 《Bulletin of the Medical Library Association》1990,78(4):364-369

The regional medical library service provided to physicians, hospitals, nurses, social workers, and health care administrators throughout Northern Ireland by the Queen's University of Belfast is described. A brief outline of the National Health Service in the United Kingdom is given, and the library service is described in terms of collections, cataloging, interlibrary loan, and reference.  相似文献   

Exercise and inflammation in coronary artery disease: A systematic review and meta-analysis of randomised trials     

Gareth Thompson  Gareth W. Davison  Jacqui Crawford 《Journal of sports sciences》2020,38(7):814-826

ABSTRACT

Current evidence suggests that chronic inflammation contributes to the development of coronary artery disease (CAD). Interestingly, exercise may constitute a method of reducing inflammation in this patient population. As such, this systematic review and meta-analysis examined the evidence generated by randomised studies that investigated the effect of exercise on inflammatory biomarkers in CAD. Literature was sought from various sources. Outcomes were pooled in a random-effects model to calculate standardised mean differences (SMD) with 95% confidence intervals (CI). Twenty-five studies were reviewed; post-intervention C-reactive protein (SMD: ?0.55 (95% CI: ?0.93, ?0.16), P = 0.005), fibrinogen (SMD: ?0.52 (95% CI: ?0.74, ?0.29, P = <0.00001)), and von Willebrand factor (SMD: ?1.57 (95% CI: ?2.23, ?0.92), P = <0.00001) values were significantly lower in exercise groups compared to controls. In addition, qualitative analyses identified evidence that supports a beneficial effect of exercise on these acute-phase reactants. However, the impact of exercise on anti–inflammatory cytokines, adhesion molecules, and chemokines is equivocal, which may be attributed to a paucity of research. Nevertheless, the findings of this review suggest that exercise induces an anti–inflammatory effect in CAD patients. Although, the quality of evidence needs to be improved by further randomised studies with high methodological qualities and large sample sizes.  相似文献

"I Follow the Blue..." A Primary Teacher and the Impact of Packaged Curricula     

Patricia A. Crawford 《Early Childhood Education Journal》2004,32(3):205-210

In the primary grades, literacy teachers often face dual and competing challenges. On one hand, they are expected to provide developmentally appropriate practice in a contextually-sensitive manner. On the other hand, they are often charged with using packaged literacy curricula that contains components that are developmentally inappropriate for young learners. This piece provides a case study of the impact of mandated packaged curricula on one such teacher's beliefs and pedagogy.  相似文献

Factors affecting treatment acceptability for psychostimulant medication versus psychoeducational intervention     

Terry A. Stinnett  Stephanie A. Crawford  Marci D. Gillespie  Michael K. Cruce  Courtney A. Langford 《Psychology in the schools》2001,38(6):585-591

Future teachers' judgments of acceptability for two common treatments for children with the Attention Deficit Hyperactivity Disorder (ADHD) label were examined. One hundred forty‐four pre‐service teachers were grouped according to their high school location at graduation (urban vs. rural) and were randomly assigned to read one of four vignettes. The content of the vignettes was held constant but label (ADHD vs no label) and treatments (special education placement vs. Ritalin) were varied. Results indicated a significant main effect on treatment acceptability for High School Location, a Label × Treatment interaction on the attention problems variable, a main effect for Label on the social problems variable, and a High School Location × Treatment interaction on the social problems variable. A number of implications can be made. Observer characteristics such as urban or rural high school experiences may influence judgments about a labeled child more than the characteristics of the child being observed. In this study, the ADHD label evoked greater expectations of attentional difficulties even when the pattern of functioning was similar to nonlabeled children. On the other hand, children with the ADHD label were judged as having better social functioning, which suggests that the ADHD label allows observers to attribute behavioral difficulties or the social problems displayed by these children to some factor that is outside the control of the child, or for which the child does not have personal responsibility. © 2001 John Wiley & Sons, Inc.  相似文献   

When and why do initially high-achieving poor children fall behind?     

Claire Crawford  Anna Vignoles 《牛津教育评论》2017,43(1):88-108

In this paper, we examine the trajectories of initially higher- and lower-achieving children from lower and higher socio-economic status families from primary school through to university in England for the first time. We also explore what explains these trajectories. This enables us to provide new insights into when and why the performance of children with similar initial achievement diverges on the basis of their socio-economic background. Our results indicate that pupils from poor backgrounds who are higher achievers in primary school fall behind their better-off but lower-achieving peers during secondary school. This suggests that secondary school may be a critical period to intervene to prevent poor children from falling behind their richer peers. Our analysis suggests that there is less divergence in performance between pupils from different socio-economic backgrounds who attend the same schools. This result is particularly strong for children with low initial achievement. While we remain cautious about the implications of these findings, they provide suggestive evidence that schools (or the sorting of pupils into schools) play an important role in explaining why the test scores of richer and poorer children diverge over time.  相似文献

Measurements of drag and lift on tennis balls in flight     

Rod Cross  Crawford Lindsey 《Sports Engineering》2014,17(2):89-96

Measurements are presented of drag and lift on new tennis balls in flight. Two video cameras were used to measure the velocity and height of the balls at two positions separated horizontally by 6.4 m. The balls were fired from a ball launcher at speeds between 15 and 30 m/s and with topspin or backspin at rates up to 2,500 rpm. Significant shot-to-shot variations were found in both the drag and lift coefficients. The average drag coefficient was 0.507 ± 0.024, independent of ball speed or spin, and lower than the value usually observed in wind tunnel experiments. The lift coefficient increased with ball spin, on average, but significant lift was observed even at very low spin. The latter effect can be attributed to a side force arising from asymmetries in the ball surface, analogous to the side force responsible for the erratic path of a knuckleball in baseball.  相似文献
