利用都柏林元数据应用包管理多样化的元数据开发

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。     

Why accessibility is hard and how to make it easier: Lessons from publishers

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.     

Using pig die and simulation to explore probability and expected values

We present a variant of the Game of Pig to introduce the concepts of probability, simulation and expected value.     

Combined individual scrummaging kinetics and muscular power predict competitive team scrum success

Scrummaging is a major component of Rugby Union gameplay. Successful scrummaging is dependent on the coordination of the forward players and the strength of the eight individuals. The study aim was to determine whether individual scrummaging kinetics and other candidate factors associated with scrummaging performance discriminate team scrum performances. Sixteen club-level forwards (stature: 1.80?±?0.1?m; mass: 99.0?±?18.2?kg) were initially divided into two scrummaging packs. A total of 10 various scrum permutations were tested, where players were randomly swapped between the two packs. Winning scrums were determined by two observers on opposite sides of the scrum. Fatigue (100?mm visual analogue scale (VAS)) and scrummaging effort (6–20 rating of perceived exertion (RPE)) were assessed following each scrum contest. Individual scrummaging kinetics were acquired through an instrumented scrum ergometer and muscular power indicated through vertical jump heights. Student’s t-tests were used to differentiate between winning and losing scrum packs. VAS and RPE were assessed using repeated measures ANOVAs. Winning scrum packs had significantly larger combined force magnitudes (p?<?.002), regardless of the player contribution calculations. Additionally, winning packs had less individual movement (p?=?.033) and higher combined vertical jump heights (p?<?.001) but were not significantly heavier (p?=?.759) than losing scrum packs. While perceived VAS and RPE values progressively increased (p?<?.001), no differences in the individual scrum magnitudes were observed between the 1st and 10th scrum (p?=?.418). The results indicated that the combination of individual forces, variation in movement and factors related to scrummaging performance, such as vertical jump height, were associated with team scrummaging success.     

Rural and suburban cluster grouping: Reflections on staff development as a component of program success

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.     

Early Literacy and the Public Library: An Opportunity of a Lifetime (of Reading)

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.     

Channel One Revisited: Prospective Teachers and the Role of American Higher Education

This study examined perceptions of college of education students and their experiences with Channel One, a privately-owned news service used in public education. Given that about one-third of middle and high schoolers in the US view the broadcast every school day, the authors surveyed 172 freshmen to discern their views and attitudes toward Channel One programming and commercials and the role colleges and universities might play in relation to this media service. While most studies on Channel One have been conducted from a K-12 point of view, the goal of this study was to reconsider the topic from the perspective of prospective teachers and post-secondary education.
