Canadian university teachers have long recognized the importance of establishing procedures for dealing with conflict of interest. More recently, they have recognized the importance of dealing with cases of academic fraud; however, compared to occurrences in universities in the United States, there seem to be few examples in Canada. Canadian academics have taken the lead in this area, securing procedures for dealing fairly with conflict of interest in the context of the needs of academic freedom through collective bargaining by faculty associations and unions under the leadership of their national organization, the Canadian Association of University Teachers (CAUT). 相似文献

Few works serve as solid a framework for the field of health sciences librarianship or provide as many insights and detailed knowledge as Introduction to Reference Sources in the Health Sciences. Now in its fourth edition, the book's editors and contributors represent an impressive range of experience, expertise, and subject knowledge appreciated by practicing librarians in a variety of settings and by students of health sciences librarianship. Jo Anne Boorkman, Jeffrey T. Huber, and Fred W. Roper answered a series of questions about the latest edition of this seminal work, and offered opinions about reference works, services, and librarians. 相似文献

Product-market planning is an inherently difficult practice. It aims at a match between consumer preference and institutional behavior. Unfortunately, consumer reactions to changes in institutional behavior are more often than not highly uncertain. This paper assumes that institutional planners should neither ignore uncertainty nor seek to avoid all actions with uncertain outcomes. This means that institutional researchers need conceptual tools that will help them deal with situations where data are sparse and time is short—where the key question that must be faced is: how much uncertainty is too much (or, how much information is enough)? This paper describes some simple, easily understood and easily used concepts that can increase the likelihood of getting good answers to this question. 相似文献

Computer-based educational assessments often include items that involve drag-and-drop responses. There are different ways that drag-and-drop items can be laid out and different choices that test developers can make when designing these items. Currently, these decisions are based on experts’ professional judgments and design constraints, rather than empirical research, which might threaten the validity of interpretations of test outcomes. To this end, we investigated the effect of drag-and-drop item features on test-taker performance and response strategies with a cognition-centered approach. Four hundred and seventy-six adult participants solved content-equivalent drag-and-drop mathematics items under five design variants. Results showed that: (a) test takers’ performance and response strategies were affected by the experimental manipulations, and (b) test takers mostly used cognitively efficient response strategies regardless of the manipulated item features. Implications of the findings are provided to support test developers’ design decisions. 相似文献
