Reading readiness varies as a function of family and environmental variables. This study of 11-year-old children (N = 39) was designed to determine if there was an additional or interactive contribution of brain structure. Evidence is presented that both environmental and biological variables predict phonological development. Temporal lobe (planar) asymmetry, hand preference, family history of reading disability, and SES explained over half of the variance in phonological and verbal performance. The results demonstrate a linear association between cerebral organization and phonological skill within socioeconomic groups. These data provide concrete evidence to support the commonly held assumption that both environmental and biological factors are independent determinants of a child's ability to process linguistic information. 相似文献

The objectives of this study were to determine nurses' use of electronic databases to inform practice. A questionnaire survey of 114 nurses working on five acute wards in a large inner city teaching hospital investigated their general use of computers and the three databases, CINAHL, MEDLINE and the Cochrane Library. Eighty-two qualified nurses responded (response rate 72%). The results show limited confidence and low frequency in using the databases. Thirty-four per cent expressed low confidence using CINAHL. Twenty-seven per cent used CINAHL on a regular basis. Twenty-two per cent never used it. Eighteen per cent were unaware that it was available locally. Knowledge and use of MEDLINE was even lower with only 18% using it regularly. Knowledge of the Cochrane Library was extremely limited, with 75% unaware of its existence. Use of a home computer and higher education were associated with higher frequency of use of CINAHL and MEDLINE. If nurses are to make use of electronic resources to contribute to evidence-based practice, effort needs to be put into ensuring that already qualified nurses have basic computer skills and specific knowledge of available resources. More emphasis should be placed on 'evidence-based' resources, such as the Cochrane library, as sources of information for practice. 相似文献
