Understanding the Information Needs of Academic Scholars in Agricultural and Biological Sciences 总被引:4,自引:0,他引:4
This study investigates the information needs of faculty and graduate students in agricultural and biological sciences. Qualitative research methods, interviews and focus groups, were used to examine what types of information these scholars need for their research, teaching and learning, how they seek that information, and perceptions. The implications for library service are discussed. 相似文献

This article chronicles the rapid expansion since 1990 of research within archival science and characterizes contemporary
archival research culture. It examines the role and state of key factors that have led to the development of the existing
research infrastructure, such as growth in doctoral education, forums for presenting and publishing research, the numbers
and size of graduate archival education programs, availability of diverse funding for research, transdisciplinary and international
research collaborations, and application of innovative research methods and tools appropriate for investigating increasingly
complex and wide-ranging research questions. An Appendix articulates and names archival research methods, including those
derived and adapted from other disciplines, with a view to adding to the “literary warrant” for archival research methods,
promoting the rigorous application of research design and methods, and providing sources for the teaching of research methods
for professional and research careers. The article concludes with recommendations about how to sustain and extend the emerging
research front. 相似文献

The Standards Committee of the Veterinary Medical Libraries Section was appointed in May 2000 and charged to create standards for the ideal academic veterinary medical library, written from the perspective of veterinary medical librarians. The resulting Standards for the Academic Veterinary Medical Library were approved by members of the Veterinary Medical Libraries Section during MLA '03 in San Diego, California. The standards were approved by Section Council in April 2005 and received final approval from the Board of Directors of the Medical Library Association during MLA '04 in Washington, DC. 相似文献

Inconsistency is often considered an indication of deceit. The conceptualization of consistency used in deception research, however, has not made a clear distinction between two concepts long differentiated by philosophers: coherence and correspondence. The existing literature suggests that coherence is not generally useful for deception detection. Correspondence, however, appears to be quite useful. The present research developed a model of how correspondence is utilized to make judgments, and this article reports on four studies designed to elaborate on the model. The results suggest that judges attend strongly to correspondence and that they do so in an additive fashion. As noncorrespondent information accumulates, an increasingly smaller proportion of judges make truthful assessments of guilty suspects. This work provides a basic framework for examining how information is utilized to make deception judgments and forms the correspondence and coherence module of truth-default theory. 相似文献
