Children with spelling deficits demonstrate significant difficulty using inflectional morphology in their writing. This study investigated whether phonological deficits account for these pronounced difficulties or if they are more accurately explained by limitations in morphological or orthographic awareness. Twenty–six 11—13–year–old children with spelling deficits, 31 younger spelling–level–matched children, and 31 age–matched children were asked to spell a series of verbs with past tense and progressive markers in dictated sentences and in list form. Performance on spelling tasks was compared to performance on phonological, morphological, and orthographic awareness tasks. Results suggest that children with spelling deficits have significant difficulty including inflections as well as spelling inflections and base words. Difficulty was most pronounced in a sentence context. Ability to spell inflectional forms was related to variation in morphological awareness in children with spelling deficits and to variation in orthographic awareness in spelling–level–matched children. 相似文献

ABSTRACT This article elucidates the dynamics of Muslim family life and the role of family values in shaping the present experiences and future aspirations of adolescent British Muslim girls. A group of Muslim girls in three schools, their parents and some of their teachers were interviewed. The research shows the dynamism of family values and the way British Muslims are socialising their daughters to construct a British Muslim identity by adopting and rejecting aspects of their Asian and British ethnicities and through a combination of freedom and control. It also argues that British Muslim young women are getting ambiguous messages about freedom and they feel ambivalent about various features of their Asian and British ethnicities. Furthermore, the research notes the stereotypical notions held by some of the teachers, which are apparently based on assumptions regarding the lives of British Muslim girls. 相似文献

The health care environment of the 1990s demands that hospital libraries develop creative strategies for providing consumer health information (CHI). Librarians at the Reuben L. Sharp Health Sciences Library at Cooper Hospital/University Medical Center have developed a multifaceted approach to the problem. Using a combination of institutional resources, private funding, and cooperative arrangements with public libraries, the Sharp Library helps to serve the consumer health information needs of the southern New Jersey community. 相似文献

Among the huge maze of resources available on the Internet, UnCoverWeb stands out as a valuable tool for medical libraries. This up-to-date, free-access, multidisciplinary database of periodical references is searched through an easy-to-learn graphical user interface that is a welcome improvement over the telnet version. This article reviews the basic and advanced search techniques for UnCoverWeb, as well as providing information on the document delivery functions and table of contents alerting service called Reveal. UnCover's currency is evaluated and compared with other current awareness resources. System deficiencies are discussed, with the conclusion that although UnCoverWeb lacks the sophisticated features of many commercial database search services, it is nonetheless a useful addition to the repertoire of information sources available in a library. 相似文献
