In the final scene of Raiders of the Lost Ark, a crate containing the object of Indiana Jones' quest is wheeled into an immense warehouse for indefinite storage and questionable research access. Unfortunately, this fate is not all that far from reality. Collections of archaeological and ethnographic materials ranging from stone axes, broken potsherds, and carved monuments to baskets, ceremonial masks, and skin canoes have been held by museums collections since the Renaissance. However, their inestimable value and unique conservation and curatorial requirements often conspire to remove them from the reach of all but the most diligent scholars. The potential of the Web to enhance the quality of research on archaeological and ethnographic collections is enormous. This paper will examine ways that one can use the Web to enhance research and improve access to a variety of materials; while there are many other resources for archaeology available on the Web, this paper focusses on museum-related sites. It will also explore the potential of the Web for innovative research strategies. Digitization of catalogs, associated documents, and images to help one locate and study collections and specific artifacts are just one approach. Others include the connection of devices to the Web, such as cameras and microscopes, the creation of virtual reference collections, and the establishment of research networks that will enhance the identification and analysis of material culture. This paper will also consider the role the Web could play in issues of cultural property, contributing to and in many ways intensifying ongoing debates of ownership, curation, conservation, and repatriation of sensitive materials. 相似文献

Chinese Studies Librarianship in North America 总被引:1,自引:0,他引:1
KarenT.Wei 《图书情报工作》2004,48(12):31-34
Although American libraries had begun collecting Chinese language materials in the 19th century, notably the United States Library of Congress in 1869, Yale in 1878, Harvard in 1879, and Berkeley in 1896, East Asian studies librarianship in North America, including China studies librarianship, was not fully developed until the 1960s. There was no formal organization that represented the interest of Chinese studies librarians because there were few of them and most of them were China scholars rather than trained librarians. More than 100 years later, the number of Chinese studies librarians in North America has increased considerably, primarily in response to the demand in the field of China studies and more recently to the needs of immigrant population and the general public who has an interest in China.This paper traces the history and growth of Chinese studies librarianship in North America, documents the development of the professional organization that represents Chinese studies librarians, and exami. 相似文献

This study examines mistreatment through the perspectives of employees with different cultural backgrounds and positions in order to understand the ways in which some voices are muted and others are privileged. Mistreatment is interactional, distributive, procedural, or systemic abuse of employees taking place at both interpersonal and institutional levels on the basis of cultural diversity. Narrative analysis of semi-structured interviews with employees of a large research and development organization revealed three types of muted narratives used to respond to mistreatment (muted-but-engaged, angrily disengaged, and resigned) as well as one type of privileged response. The narratives provided evidence of two processes by which voices became muted: repeated silencing over time and silencing through ambiguity of policies. 相似文献

OBJECTIVE: This article presents the results of complementary research studies on the behaviors of hospital clinicians in asking clinical questions and the relationship between asking of questions, outcome of information searches, and success in problem solving. METHODS: Triangulation in research methods--a combination of mailed questionnaires, interviews, and a randomized controlled study--was employed to provide complementary views of the research problems under study. RESULTS: The survey and interviews found that clinical problems (concerned mainly with therapy and equipment or technology) were expressed as statements rather than questions (average number of concepts = 1.7), that only slightly more than half (higher for doctors) of problems could be solved, and that the majority of clinical questions were not well formed. An educational workshop however improved clinicians' formulation of questions, but the use of structured prompting was found to improve building of hypotheses in the doctors' group without training. The workshop also improved satisfaction with the obtained information and success in problem solving. Nonetheless, for both the experimental and control groups, more structured and complete questions or statements did not mean higher success rates in problem solving or higher satisfaction with obtained information. CONCLUSION: The triangulation methods have gathered complementary evidence to reject the hypothesis that building well-structured clinical questions would mean higher satisfaction with obtained information and higher success in problem solving. 相似文献

This paper addresses several misunderstandings about the nature of the FBI's Central Records System. Although depicted in popular culture and much of FBI historiography as a tool for the Cold War suppression of American radicals, the FBI's records system grew out of Department of Justice systems already in place before J. Edgar Hoover became Director in 1924. The system grew in size and complexity according to the demands placed on it by the changing priorities of the FBI's criminal and intelligence missions, guided by a “progressive” drive for efficiency through centralization. 相似文献
