Large scale statewide library cooperation using information technology and wide area networks dates back to the early 1980s with efforts such as the Florida Center for Library Automation and, more recently, the LOUIS Project in Louisiana (see JAL January 1994) and OhioLink (see JAL September 1995). Early efforts were usually focused on the implementation of library information management systems and the provision of shared access to locally held collections, and they often still are. In the 1990s, though, we are witnessing a shift in statewide cooperative use of networks to provide principally access to bibliographic and full-text resources not held locally and usually provided by commercial vendors for use by libraries. As the case studies in this column illustrate the development of funding sources, the technical implementations and support, and the management organization differ from state to state. They reflect, though, the incremental shift in the information landscape towards “electronic libraries”. I choose the word incremental intentionally to reflect that this change has not (at least so far) been anywhere near as rapid or revolutionary as many expected. Nevertheless, what has happened in about 15 years is quite dramatic. It portends a different kind of academic library.—CBL, University of Maryland, College Park. 相似文献

During the second year of life, babies actively play with sounds they produce. Their sound-play often has musical qualities such as pitch, rhythm, and melodic contour, but it is not the same as singing. Singing is a complex activity, one requiring skills that usually take the entire preschool years to develop.Lyle Davidson is a professor at the New England Conservatory of Music, Boston, MA. W. George Scarlett is a professor of child psychology at Assumption College, Worcester, MA. The research reported on in this article is based on work done at Project Zero, Harvard School of Education, Cambridge, MA.The research reported here was part of a larger study of early symbolization carried out at Project Zero, Harvard School of Education, and funded by the Spencer and Carnegie foundations.

This paper explores some of the issues and benefits surrounding the process of accreditation of prior experiential learning (APEL) as one key institutional 'building block' for meeting the needs of adults who wish access to UK higher education institutions (HEIs) course provision. Arguments are advanced whereby APEL could help to 'unlock doors' to HEIs for those (mostly part-time students), who have traditionally been denied access or advanced standing to HE courses because of personal, socio-economic or institutional constraints. The paper also provides a basis for APEL based on educational grounds. Reference to a three year study/project in a Canadian institution, where criteria were evolved that eventually led to the establishment of APEL policy and procedures along with the evolution of the necessary infrastructure, is also made. APEL is also presented as a human resource/career development process that can gather momentum, gain commitment and support from the private sector. 相似文献

With technology increasingly being introduced into classrooms worldwide, stakeholders are asking whether ICT provides educational value. It is not simply having access to technology but how teachers use it that will determine its worth to education. Thirty-three teacher-designed technology-based tasks from eight subject areas were analysed for their effective use of ICT, and their potential to involve students in constructivist learning. Few of the tasks made effective use of ICT for meaningful learning, for reasons associated with teachers’ beliefs, attitudes, and missing TPACK components or competencies. These factors provide the basis for a model of areas to target when structuring professional development courses to help teachers better utilize educational ICT to design meaningful learning tasks. 相似文献

Thrombotic risk factors may contribute to premature coronary artery disease (CAD), in addition to the conventional risk factors. There is paucity of data on studies evaluating the role of thrombotic factors in premature CAD in Indian patients. Thus a case–control study was performed to evaluate the role of thrombotic and atherogenic factors in young patients with angiographically proven CAD who are on treatment with statins and anti-platelet drugs. 152 patients (≤55 years) with angiographically proven CAD and 102 asymptomatic controls were recruited. Clinical and biochemical data were obtained in both groups. Blood levels of thrombotic factors-fibrinogen, antithrombin-III, tissue-plasminogen activator (t-PA), plasminogen activator inhibitor-1 (PAI-1), von-Willebrand factor (v-WF), lipoprotein(a) [Lp(a)] and homocysteine were analyzed. Patients had high levels of conventional CAD risk factors (diabetes mellitus, smoking, hypertension, dyslipidemia and positive family history) compared to controls. Logistic regression analysis revealed that low antithrombin-III (odds ratio/OR 11.2; 95 % confidence interval/CI 2.29–54.01), high fibrinogen (OR 6.04; 95 % CI 1.09–33.21) and high Lp(a) (OR 4.54; 95 % CI 0.92–22.56), as important, independent risk factors in patients. PAI-1(OR 0.15; 95 % CI 0.03–0.69) levels were significantly lower in patients. But other thrombotic risk factors studied (t-PA, v-WF and homocysteine) were comparable among patients and controls. The treatment using statins and anti-platelet drugs might be contributing to the control of some of the thrombotic risk factors. The strategies aiming at lowering the levels of thrombotic risk factors along with conventional risk factors may be useful in primary and secondary prevention of CAD. 相似文献

In the United States, Congress has had a long-standing interest in consumer privacy and the extent to which company practices are based on fair information practices. Previously, public policy was largely informed by anecdotal evidence about the effectiveness of industry self-regulatory programs. However, the Internet has made it possible to unobtrusively sample web sites and their privacy disclosures in a way that is not feasible in the offline world. Beginning in 1998, the Federal Trade Commission relied upon a series of three surveys of web sites to assess whether organizations post online privacy disclosures and whether these disclosures represent the U.S. definition of fair information practices. While each year's survey has provided an important snapshot of U.S. web-site practices, there has been no longitudinal analysis of the multiyear trends. This study compares a subset of equivalent individual-level web-site data for the 1998, 1999, 2000, and 2001 web surveys. Implications for using this type of research to inform public policy are discussed. 相似文献
