This study sought to determine if exposure to two communication-oriented activities, videotapes and public service announcements, accounts for changes in substance use among adolescents participating in the Drug Resistance Strategies Project's keepin' it REAL adolescent substance use prevention curriculum. Middle-school students (4,734, 72% Latino) responded to questionnaires related to these analyses. An analysis of covariance (ANCOVA) model was fit separately to six substance use outcomes. The results suggested that intervention students who saw four or five videos engaged in less substance use in the past month than did students who saw fewer videos. Having seen the PSAs one or more times did not predict the reported change in substance use.  相似文献

DC词表的维护:实践、策略与模型   总被引：2，自引：1，他引：2  

托马斯·贝克  夏翠娟  刘炜 《图书馆杂志》2004,23(5):48-54,60

DCMI维护着一个包含众多元数据术语的词表，其中最主要的是包括15个元素的都柏林核心。然而，DCMI所关注和讨论的并不只是这个核心集，以及围绕这个核心集的实践、策略和模型，DC元数据模型已经由最初的单一模型进化成一个完整的框架，可以通过这个框架对应用DC元数据的各种实践进行评估。这些术语及其以前的版本现在都由统一资源标识符(URI)来标识，并建立了网页和形式化的schema文档，在注册系统中被编成索引，在具体的应用纲要(application profiles)中被引用。DCMI正在寻求一种简单易行的维护机制，一方面推荐使用不断变化和增长的核心标准，另一方面承认和重用其它的词表作为必要的补充，这两者之间需要建立一种平衡。  相似文献

The use of personal digital assistants in the health sciences: results of a survey.     

Sandra L De Groote  Marceline Doranski 《Journal of the Medical Library Association》2004,92(3):341-348

OBJECTIVES: The purpose of this study is to determine how personal digital assistants (PDAs) are used on an academic health sciences campus to define the level of training and support the library can provide to the students and faculty. METHOD: A Web-based questionnaire was developed. A total of 1,538 health sciences faculty and residents were sent an email message requesting participation. Data from the returned surveys were analyzed with SPSS. RESULTS: Sixty-one percent of survey respondents used PDAs. The address book, date book, and calculator were the most common uses reported for PDAs. Residents also reported a high use of drug databases on their PDAs. Most survey respondents indicated they would like to learn more about clinical resources for PDAs. CONCLUSIONS: Many opportunities exist for librarians to provide training and support for PDAs, in addition to evaluation and promotion of clinical software for PDAs.  相似文献   

Grundlagen des Burrows-Wheeler-Kompressionsalgorithmus     

Jürgen Abel 《Informatik - Forschung und Entwicklung》2004,39(1):80-87

Der Burrows-Wheeler-Kompressionsalgorithmus hat als ein universelles Kompressionsverfahren in den letzten Jahren aufgrund seiner hervorragenden Kompressionsraten und hohen Verarbeitungsgeschwindigkeiten eine bemerkenswerte Beachtung erfahren. Das Herzstück des Algorithmus stellt die sogenannte Burrows-Wheeler-Transformation dar. Es handelt sich bei dieser Transformation um eine Permutation der Eingabedaten, welche Zeichen mit ähnlichem Kontext nahe beieinander anordnet. Die Transformation sowie die zugehörige Rücktransformation werden zusammen mit den weiteren Stufen des Algorithmus in einer gegenüber der Standardversion verbesserten Variante vorgestellt und die Ergebnisse mit denen anderer Datenkompressionsalgorithmen verglichen.  相似文献

Setting the Students’ Bearings and Balance in Appraisal     

Barbara L. Craig 《Archival Science》2005,5(2-4):391-402

The author, a professor at the University of Toronto, touches briefly on the extensive and rich archival literature that supports the teaching of macroappraisal, but notes that this is not the only educational material she offers her students when teaching appraisal theory. She discusses the usefulness to archivists of literature from the fields of ethnography, organizational knowing, records in history, personal documentary behaviour, memory, and communications, noting that the use of texts from these fields can encourage students to reflect on their own presumptions and to develop a taste for the wide reading and research that must support appraisal.  相似文献
