在中国国家图书馆建馆100周年庆祝大会上的致辞

各位嘉宾、各位朋友： 下午好。 非常荣幸受邀参加此次中国国家图书馆百年馆庆的盛大活动。很高兴能够来到这里,这也是我担任国际图联主席以来的首次正式访问。中国国家图书馆是亚洲乃至世界上最大的图书馆之一。它也是世界上最大的中文文献藏家。众所周知,     

Parent Involvement,Influence, and Satisfaction in Magnet Schools: Do Reasons for Choice Matter?

This paper explores the relationships between parents' reasons for choosing a magnet school and their levels of satisfaction, involvement, and influence with the school. Data are reported from over a thousand magnet school parents in two urban districts. The results suggest three general findings: (1) As reported in previous research, magnet school parents choose schools for a wide array of reasons and are highly satisfied with their chosen school; (2) parents' reasons for choice are important predictors of their levels of satisfaction, influence, and involvement with the school; and (3) parents who choose for values reasons, as compared to other reasons, are more likely to be involved in and satisfied with their school of choice and report that parents have influence over school decisions.     

The TREC-5 Confusion Track: Comparing Retrieval Methods for Scanned Text

A known-item search is a particular information retrieval task in which the system is asked to find a single target document in a large document set. The TREC-5 confusion track used a set of 49 known-item tasks to study the impact of data corruption on retrieval system performance. Two corrupted versions of a 55,600 document corpus whose true content was known were created by applying OCR techniques to page images. The first version of the corpus used the page images as scanned, resulting in an estimated character error rate of approximately 5%. The second version used page images that had been down-sampled, resulting in an estimated character error rate of approximately 20%. The true text and each of the corrupted versions were then searched using the same set of 49 questions. In general, retrieval methods that attempted a probabilistic reconstruction of the original clean text fared better than methods that simply accepted corrupted versions of the query text.     

A Task-Oriented Non-Interactive Evaluation Methodology for Information Retrieval Systems

Past research has identified many different types of relevance in information retrieval (IR). So far, however, most evaluation of IR systems has been through batch experiments conducted with test collections containing only expert, topical relevance judgements. Recently, there has been some movement away from this traditional approach towards interactive, more user-centred methods of evaluation. However, these are expensive for evaluators in terms both of time and of resources. This paper describes a new evaluation methodology, using a task-oriented test collection, which combines the advantages of traditional non-interactive testing with a more user-centred emphasis. The main features of a task-oriented test collection are the adoption of the task, rather than the query, as the primary unit of evaluation and the naturalistic character of the relevance judgements.     

Environmental Education Research as Profession,as Science,as Art and as Craft: Implications for guidelines in qualitative research

The view taken by any particular educational researcher of the desirability and potential usefulness of guidelines for qualitative research seems likely to depend upon the way in which the activity of 'doing educational research' is itself conceptualised. The implications of a number of possible positions on this question are examined. It is argued that the existence of such a range of positions is likely to continue, but that there may be, nevertheless, a limited role for generally applicable research guidelines if their purpose is appropriately defined.     

University of California Peer Review System and Post-tenure Evaluation

The peer review system at all campuses of the University of California is a long standing program of pre- and post-tenure evaluation. All faculty are reviewed on a schedule of 2 to 4 years by department colleagues, the dean, and a campus faculty committee which normally results in a merit increase. This system of pre- and post-tenure review throughout a faculty members' career poses a substantial workload for faculty, departments, and the campus; but it is regarded by faculty and campus administrators as crucial to maintaining a faculty of very high quality. This article describes the well-established review process, which may provide ideas for those institutions planning on enhancing their approaches to peer review .     

From Positive Reinforcement to Positive Behaviors: An Everyday Guide for the Practitioner

There are various opinions concerning the value of positive reinforcement when discussing modifying behaviors of young children. In some cases, individuals considered positive reinforcement difficult to implement and, in extreme cases, even felt it to be detrimental. Educators often use praise interchangeably with positive reinforcement when indeed an important distinction exists between the two. This paper discusses the differences between positive reinforcement and praise and demonstrates how to effectively apply positive reinforcement to help manage behavior of young children.
