AIM: In 2002, a discussion in the United Kingdom (UK) between South-west Information for Clinical Effectiveness (SWICE) librarians and a member of the South Australian Department of Human Services Libraries' Consortium (SAHSLC) raised the possibility of developing an after-hours virtual reference service between the two consortium groups. The aim of the service is to put medical practitioners in contact with a librarian when urgent help is required in finding clinical medical information after hours. METHODS: A trial project has begun and has been given the name 'Chasing the Sun'. The service will make use of time-zone differences between the UK and Australia, so that librarians at work in another country will be able to answer urgent patient-related queries that cannot wait until normal office hours. RESULTS: This paper looks at the development of 'Chasing the Sun' from initial concept, funding proposal and trial project stage to implementation. It includes details of the groundwork, software evaluation, trials, outcomes, cost and benefits, future directions and potential problems yet to be experienced or overcome. CONCLUSION: This service is the first of its kind between health libraries in the world and offers potential for future worldwide expansion. 相似文献

Despite the laudable intent of various educational initiatives in raising the achievement level of all children, limited progress
has been made. In an effort to diminish the achievement gap of students of color, some researchers have examined the cultural
relevancy of the curriculum in promoting student achievement. The purpose of this mixed methods study was to explore the preferences
of African American children toward culturally relevant and non-culturally relevant lessons, through a six-week series of
lessons in an American History classroom. Critical Race Theory and Racial Identity Development provided the theoretical underpinnings
of this study. This study takes place in an ethnically diverse high school in Colorado. Culturally relevant lessons were rich
in oral traditions, music, historical connections, and a structured culturally relevant field trip. Non-culturally relevant
lessons were administered devoid of cultural referents, and utilized the existing curriculum guide. Study results revealed
statistically significant findings for African American children’s preferences for culturally relevant lessons. These lessons
were found relevant to their culture when administered by a culturally responsive and caring teacher. Recommendations are
made for educators and administrators in promoting achievement through culturally relevant lessons and curriculum. 相似文献

In a previous simulation study of methods for assessing differential item functioning (DIF) in computer-adaptive tests (Zwick, Thayer, & Wingersky, 1993, 1994), modified versions of the Mantel-Haenszel and standardization methods were found to perform well. In that study, data were generated using the 3-parameter logistic (3PL) model and this same model was assumed in obtaining item parameter estimates. In the current study, the 3PL data were used but the Rasch model was assumed in obtaining the item parameter estimates, which determined the information table used for item selection. Although the obtained DIF statistics were highly correlated with the generating DIF values, they tended to be smaller in magnitude than in the 3PL analysis, resulting in a lower probability of DIF detection. This reduced sensitivity appeared to be related to a degradation in the accuracy of matching. Expected true scores from the Rasch-based computer-adaptive test tended to be biased downward, particularly for lower-ability examinees 相似文献

Two experiments are reported in which children's study behaviour was manipulated systematically within a behavioural paradigm. Both studies were carried out in the remedial department of a large, modern Secondary school in England by a woman teacher. The first involved an individual, a boy whose study behaviour was controlled using self‐recording in a reversal design. On‐task behaviour increased whilst maladaptive responses were reduced and there was a pronounced improvement in the boy's attitude to school work. The second study was a group intervention employing self‐recording which was again successful in improving the on‐task behaviour rate. At the same time it proved possible to gain measures which show clear evidence of improvement in both the quality and quantity of written work produced by the group. In both studies there was some evidence of generalisation of effects. 相似文献
