The librarians at four hospital libraries describe the electronic reference service, "Ask A Librarian," offered at their institutions. The hospitals are vastly different in size and in number of library staff, and offer the "Ask A Librarian" service to different clientele. The article illustrates that both large hospitals with a large library staff and small hospitals with a solo librarian and some volunteers can offer this type of service. 相似文献

Previous research has confirmed peers and parents as significant agents of socialisation with respect to young people’s sexuality. The aim of this cross-sectional cohort study was to examine how parental and peer variables predict young women’s sexual behaviour and sexuality-related thoughts and emotions, and whether perceived peer influences mediate the relationship between parental variables and young person sexuality. A total of 560 female high school students of 1st (mean age 15.56 years) and 3rd grade (mean age 17.55 years), selected by means of two-stage stratified probability sampling participated in the research. Results confirmed that peer variables explained considerably more variance in participant sexuality than parental variables. Indirect parental communication about sexuality was a significant positive predictor of sexual behaviour and sexuality-related thoughts and emotions in both subsamples. The strength of direct and indirect influences of parents and peers on young people’s sexuality is determined by the age of the young person and specific aspects of adolescent sexuality. Perceived percentage of sexually active peers was the only mediator in older participants, while in the younger subsample, additional peer variables mediated the association between some parental and sexuality variables. In the discussion, special attention is given to implications of these results for planning future forms of comprehensive sexual education. 相似文献

The purpose of this study was to investigate the hypothesis that the manner in which a reading disability is defined will influence the conclusions that are made about the characteristics of the disability. To test this hypothesis, learning disabled and normally achieving children, aged 6 to 14, were administered tasks measuring grammatical, shortterm memory, phonological, reading, and visual-spatial skills. The poor readers were divided into groups of poor readers with
These children were compared with children who had normal reading scores. Children with deficits in phonics and/or word recognition scored significantly below normal on all the cognitive tests, except some of the visual-spatial tasks. Reading comprehension difficulties were characterized by average phonics, word recognition, and language skills but below average scores on some memory tasks. Slow readers had cognitive profiles similar to the normal children. The presence of a deficit in phonics and/or word recognition constituted the basis of the most serious impairment of language and memory functioning. Reading disabled children, defined in this manner, appear to be reasonably homogeneous in regard to the presence of language and memory problem. There does not appear to be evidence for a distinctive non-language impaired subtype within this type of reading disability. Children with low comprehension scores and/or slow readers did not have language problems. The definition of a reading disability appears to determine the subtypes and characteristics of reading disability that will emerge. 相似文献

Mergers are common phenomena in higher education institutions. Improving educational quality is typically one of the stated goals of university mergers. Yet, little information exists about how merging institutions approach this goal. This paper presents results from a study of planning documents created prior to four mergers in the Finnish higher education system. These documents show that there was little concrete attention given to the educational issues related to the mergers. Most attention was placed on administrative issues and issues related to research. When educational issues were mentioned, it was almost always in the form of vague goals with few details provided about how the goals were to be reached. We conclude that this lack of attention to the educational aspect of mergers is a significant weakness of the planning process in these mergers. 相似文献
