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

Considerable research has documented that successful performance in interceptive tasks (such as return of serve in tennis) is based on the performers’ capability to capture appropriate anticipatory information prior to the flight path of the approaching object. Athletes of higher skill tend to fixate on different locations in the playing environment prior to initiation of a skill than their lesser skilled counterparts. The purpose of this study was to examine visual search behaviour strategies of elite (world ranked) tennis players and non-ranked competitive tennis players (n = 43) utilising cluster analysis. The results of hierarchical (Ward’s method) and nonhierarchical (k means) cluster analyses revealed three different clusters. The clustering method distinguished visual behaviour of high, middle-and low-ranked players. Specifically, high-ranked players demonstrated longer mean fixation duration and lower variation of visual search than middle-and low-ranked players. In conclusion, the results demonstrated that cluster analysis is a useful tool for detecting and analysing the areas of interest for use in experimental analysis of expertise and to distinguish visual search variables among participants’. 相似文献

Abstract Students develop robust mental models of teaching and learning during their school years, and as such, often teach as they were taught—possibly perpetuating practices that limit intellectual inquiry in classrooms. This paper reports on an analysis, using a conceptual framework and NUD?1ST software, of a cohort of 3rd‐year teacher education students' reflections on changes in their mental models following their experiences in a problem‐based learning (PBL) topic. Results provide evidence that students do report changing mental models in areas such as (a) the value of case studies for engaging with subject content, motivating learning, and connecting theory with practice; (b) self‐reflection and peer collaboration for cognitive and professional growth; and (c) processes of inquiry for developing self‐regulated learning practices. 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 is designed to identify the underlying satisfaction dimensions gained through engagement in target shooting as a serious leisure pastime. The instrument design was based on the Leisure Satisfaction Scale. A total of 5502 useable surveys were collected through the Internet and a website related to target shooting and gun ownership. The results revealed eight dimensions: self-actualization, social interaction, location aesthetic, respite, physical benefit, connection and hedonic pleasure, which supplied the primary satisfiers of engaging in target shooting as a serious leisure activity. The demographic profile and dimensions of satisfaction may serve to dispel commonly held stereotypes of shooting hobbyists and those involved in gun ownership. The findings have important implications for leisure researchers and practitioners, to industry, both leisure and firearm related, and the target shooting community at large. This study adds to the literature of both target shooting and serious leisure. 相似文献
