How has Item Response Theory helped solve problems in the development and use of computer-adaptive tests? Do we need to balance item content with computer-adaptive tests? Could we use IRT to evaluate unusual responses to computer-delivered tests?  相似文献

The role of the literary agent and the reception granted agents by publishers have changed markedly over the course of the twentieth century. Henry Holt’s views of agents, written in the first decade of the century, help define the status and activities of agents at that time. These are compared with the role of agents today, using archival sources, the book trade literature, and interviews. Thomas L. Bonn, review editor of this journal, is a librarian, Library at State University College at Cortland. He is the author ofUnder Cover: An Illustrated History of American Mass Market Paperbacks andHeavy Traffic and High Culture: The New American Library as Literary Gatekeeper. He is working on a study of American literary agents.  相似文献

The study examined the social‐information‐processing skills of kindergarten children with developmental learning disabilities (LD) utilizing Crick and Dodge's (1994) model of children's social adjustment as a theoretical framework. Participants consisted of 20 kindergarten children with developmental LD who attended three integrated kindergartens and 20 children without developmental LD from the same kindergartens. Participants were assessed on social‐information‐processing skills, feelings of loneliness, sense of coherence, and teachers' ratings of behavioral problems and positive resources. The results indicated that girls with developmental LD performed significantly lower on two information‐processing steps—the response decision and the enactment steps—than did girls without LD. Such differences were not found for boys. The results also showed that the social‐information‐processing skills of children with developmental LD were correlated with teachers' ratings.  相似文献

The article sets off with a brief summary of the history of appraisal and disposal of records as processed at the National Archives of Iceland (NAI) since its establishment in 1882 to present times. Rules on appraisal and disposal of records introduced in 1900, 1911, and 1916 were ignored and all records were kept. Status quo remained until 1985 when a new National Archives Act was passed. The appraisal and disposal process adopted then is described and explained. It included the publication of instructions on records management as well as forms relating to records management. The influence of acts of law on the appraisal and disposal process is explained. Finally the experience with the arrangement of organised appraisal in Iceland is described.  相似文献

The 1991 Janet Doe lecturer describes the vision held by the founders of the Medical Library Association of medical information being readily accessible to health professionals no matter how far they were located from major medical centers, and traces the pursuit of this vision to current outreach activities.  相似文献
