大英图书馆长期大规模的资源数字化产生了大量的声像资源,这些项目由于大部分是由外来资金资助并与外单位合作,其产生的资源和元数据往往散藏在各个不同部门,元数据的有无及其结构格式区别很大,这给检索和使用带来极大的不便,因此跨库检索势在必行。在推行标准化的同时,大英图书馆考虑到各个特藏的功能和服务特点,允许足够的灵活性。他们遵循的一个主要原则是,如果数据是在大英图书馆系统之外建立的,该系统应该具有生成和输出基本元数据记录的功能,其格式应该与至少一种大英图书馆所支持的标准兼容,对元数据记录的最低要求是要与大英图书馆元数据应用纲要(BL Application Profile,B-LAP)一致。B-LAP是用XML标注、以都柏林元数据核心元素为基础的应用纲要。本文特别讨论了利用都柏林核心元数据应用纲要来支持检索的策略,以及如何应用纳要来控制在数字化资源过程中产生的多样化的元数据格式,并为各种早期的系统之间在高层次上提供互操作性。本义还描述了该系统的构建及如何支持横跨各种不同数据库之间的检索。  相似文献

The requirements for providing publications in an accessible form have recently become much clearer and easier to comply with. They are based on standard web accessibility guidelines that are commonly used globally, and the format for interchange is EPUB, a format many publishers already produce in their normal production process. Nevertheless, accessibility still proves difficult to accomplish for most publishers. This article refers to informal interviews and the author's own experiences to examine the issues that are challenging to publishers and their suppliers, assessing the level of effort required to address them, discussing the factors that make them difficult, and suggesting strategies for reducing the effort required. The article concludes that the best solution is to build accessibility into the publication workflow upfront as this can dramatically reduce the cost and effort required to make publications accessible.  相似文献

The purpose of this investigation was to examine the efficacy of a new preschool oral language and early literacy curriculum package (Teaching Early Literacy and Language [TELL]) for children with developmental speech and/or language impairment (DSLI) either as a primary (e.g., specific to speech and/or language) or secondary impairment (e.g., developmental delay that includes DSLI). Participants included 118 children (30 females, 88 males, M age = 53.58 months) with DLSI and their 29 preschool teachers. The design was a randomized controlled trial (RCT) with assignment to experimental versus contrast conditions at the classroom level. Teachers in TELL classes received formal training, in-class support, and mentoring to implement the curriculum. Dependent measures for the children included scores on the Clinical Evaluation of Language Fundamentals-Preschool 2nd edition (CELF-P2), the Phonological Awareness Literacy Screening for Preschool (PALS-PreK), the Renfrew Bus Story (BUS), and a receptive and expressive vocabulary measure developed for this investigation (VOCAB). Results indicated that when compared to the contrast group, children in the TELL condition demonstrated greater gains on the phonological awareness subtest of the CELF-P2, the sentence length score of the BUS, the letter sounds, beginning sound awareness, and rhyme awareness subtests of the PALS-PreK, and VOCAB. Results suggest that the TELL curriculum package has promise for promoting gains in early literacy and oral language skills in preschool children with DLSI.  相似文献

This paper reports on research into the operation of English further/higher education, with a focus on the role of partnerships in supporting the massification of higher education. The research draws on the bottom‐up policy implementation tradition to provide analysis of the effects on partnerships of a quasi‐marketised environment. The rationale and effects of market orientated policy are discussed with reference to empirical data from college staff and partnership managers. In employing the concept of the ‘street‐level bureaucrat’ as an agent of policy implementation, this research contributes to the interpretation of policy and partnership which has previously been unexplored within the further/higher education context. Conclusions are drawn with implications for the development of college higher education delivered in partnership.  相似文献

Staff development practices that successfully implemented long‐term applications of cluster grouping in two districts are analyzed, compared, and reviewed. Parallel practices and differences are discussed concerning program beginning, implementation, and maintenance. Conclusions are drawn and six steps for use and consideration by others engaged in gifted program development and implementation are suggested. These steps are: (1) conversations, (2) research, (3) choosing a course of action, (4) implementation, (5) supporting the new program initiative, and (6) maintenance and growth.  相似文献

In this article, author Bill Ptacek says that the future is now, and, at least from the 1970s through today, in the field of early childhood work, the future has come so fast that it is constantly upon us. That reality means that those concerned about young children in libraries have been about adaptation on a continuing basis. In this world of rapid change, innovation is constant: City firefighters come to the libraries in uniform to read stories to children, library outreach specialists take programs to daycare centers in their communities, and staff members create a space in a library devoted to early childhood reading. This tradition of rapid change means that the early childhood staff of most large public libraries in North America is changing for the future on a regular basis. The work unit should be considered seriously as one model for 21st century public library reform.  相似文献

This study investigated the effects of a brief meditation intervention on perceived stress, mindfulness, and sleep quality for college freshmen who have aged out of foster care. Thirty-six youth who had aged out of foster care and enrolled at a large midwestern 4-year university (n?=?16 experimental group, n?=?20 control group) participated in a study in which they were assessed three times on the dependent variables. Students also participated in a focus group after the intervention ended. Four sessions of the brief mindfulness intervention resulted in significant short-term reductions in stress levels and increases in sleep quality. Finding effective personal interventions to increase chances for college success for students with histories in foster care can also offer potential insight toward the development of educational models and resources for other vulnerable college student populations.  相似文献
