Thierry Mauban 《对外大传播》2008,(4):62-63
"双语视窗"栏目从2006年开办至今,已经走过了2年的历程,这些由在华外国友人撰写的小文章,以他们在华所见所闻为切入点,生动具体地反映出东西方观念、习俗的异同,也向我们提出了一个个既有趣又值得深思的问题。栏目一再连载得益于读者反馈中的正面回应。"不识庐山真面目,只缘身在此山中",换一个角度,从外国友人目光的折射中审视一下自己,更有助于全面地了解我们自身。同时,本栏目采用英汉对照形式,这些原汁原味的英文不仅有助于加深对作者原意的理解,也是一本学习现代英语的鲜活教材。 相似文献

Donato Tamblé 《Archival Science》2001,1(1):83-100
Archival theory in Italy has a long tradition, going back as far as the second half of the nineteenth century, and with roots
in the 17th and 18th centuries. Central theme in the theory is themetodo storico, the principle of provenance, for the first time expressed in the late 19th century by Bonaini and Bongi. In the following
decades archivists like Casanova and Cencetti were among the leading authors. Elio Lodolini assigned himself the task to synthesize
ideas and notions, within a clear distinctions between records (registratura) and archives. One of the overall characteristics
of the rich Italian literature is the stressing of the cultural value of archives.
I have twice treated before the theme of archival theory in Italy from the fifties up to the nineties. The first time on the
occasion of the 25th anniversary of theScuola speciale per Archivisti e Bibliotecari dell'Università degli Studi “La Sapienza” di Roma in 1989, when there was an international round table on archival science in the State Archives of Rome. My essay,Italian archival science today, has been published in the proceedings of the meeting (cfr. Donato Tamblé,L'archivistica in Italia oggi, inStudi sull'archivistica, by Roma: Elio Lodolini, 1992). Some years later, in 1993, I published a book on contemporary Italian archival theory (Donato
Tamblé,La teoria archivistica italiana contemporanea (1950–1990). Profilo storico-critico (Roma, 1993) which was the sequel to the volume of Elio Lodolini on Italian archival history — (Lineamenti di storia dell'archivistica italiana (Roma, 1991). The purpose of my book was that of locating and identifying the scientific object of archival science as it
developed and was clarified in the thinking and in the lucubration of the contemporary Italian Archivists. 相似文献

Characteristics of early adopters of end-user online searching in the health professions 总被引:1,自引:0,他引:1
J G Marshall 《Bulletin of the Medical Library Association》1989,77(1):48-55
This paper examines end-user, online searching using data from a questionnaire mailed to 150 Canadian health professionals in practice settings. The response rate was 83% (n = 124). The data provide a demographic profile of early adopters of end-user searching in the health care community. Positive correlations with the user's level of implementation of end-user searching were found for the following variables: amount of time spent in research activities, amount of system training received, and use of Medical Subject Headings (MeSH). There was a negative association between the amount of time spent in patient care and implementation level. General practitioners and family physicians had lower implementation levels than physicians in other specialties. Successful implementers were more likely to be computer literate and to place a high value on formal information sources such as books, journals, and libraries. Health professionals using so-called "user-friendly" or menu-based software had lower levels of personal commitment to using online databases, as measured by a combination of continuance of use, willingness to pay personally, type of recommendations made to colleagues, and hardware ownership. 相似文献

This study was designed to examine children's attitudes toward the role of sports in determining social status, as well as the activities in which children prefer to participate. A total of 227 boys and 251 girls in Grades 4, 5, and 6 completed a questionnaire to determine which criteria were most important in determining personal, female, and male popularity. Personal popularity was answered by the girls and boys according to "what would make you well liked by your classmates." Female and male popularity was determined by asking both girls and boys to decide "what would make (girls, for female subjects, and boys, for male subjects) well liked by your classmates." A comparison of results from the Buchanan, Blankenbaker, and Cotten (1976) investigation and the present study indicated that, in the last 15 years, appearance has become more important and academic achievement less important in determining personal popularity for girls. For boys, the comparison revealed that sports have become more important and academic achievement less important in determining personal popularity. Boys reported sports to be the most important determinant of personal and male popularity and appearance as the most important determinant of female popularity. Sports and appearance became more important for boys with each higher grade level. Girls reported appearance to be the most important determinant of personal, male, and female popularity. For girls, appearance became more important with each higher grade level. A comparison of results from the Buchanan et al. (1976) and the present study indicated that the activities in which girls and boys preferred to participate have changed.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

The Alfred Taubman Medical Library at the University of Michigan has offered instruction in online literature searching to third-year pharmacy students as a component of the course "Drug Information and Scientific Literature Evaluation" since 1983. In the spring of 1989, a follow-up study was conducted to assess the impact of instruction on four classes of graduates. Of a pool of 151 graduates, 90 (60%) responded to a mailed questionnaire on their use of information and computerized literature searching. The respondents were divided into four subgroups: end-user searchers, users of intermediaries, end users who used intermediaries, and those who did not use computerized literature search systems. Seventy-two percent of the respondents used some type of computerized literature searching, and 42% performed their own searches. The four subgroups differed in general computer use, familiarity with MEDLINE search terminology, information use, reasons for using or not using literature searching, and characteristics of searches (i.e., type, time frame, amount, and frequency). Training in end-user search systems appears to have had an impact on the continued use of computerized literature searching several years after the formal educational program. 相似文献

Since a sizeable hospital must have a library, it must have a library committee. Like all hospital committees, this one is to help maintain standards of medical care and to mediate between staff and administration. Unlike others, it clusters around one elected member (the chairman) and one employee (the librarian). A dynamic librarian can, and should, influence and inspire the committee's deliberations; and must be able to depend upon the support of the physician members of the committee. 相似文献
