An experimental cancer information service using AIM-TWX     

N G Blase  C J Stock 《Bulletin of the Medical Library Association》1972,60(1):115-120

The Pacific Northwest Regional Health Sciences Library and the Washington/Alaska Regional Medical Program jointly conducted a service to provide photocopies of articles on cancer topics within twenty-four hours after receiving telephone requests for information from Central Washington physicians. AIM-TWX was utilized as the initial source of references whenever possible, and its benefit as such was evaluated. In the three-month experimental period, twenty-seven requesters made fifty-six requests and received photocopies of 185 articles; the estimated total cost was $1,000, less than $18 per request.A sample of requests showed AIM-TWX to have reduced the total work time per search; moreover, when it was used, AIM-TWX retrieved more than 70% of the articles selected to be sent. Physician response indicated that the service was both needed and appreciated. Further investigation by a similar information service is suggested.  相似文献   

Cross-cultural adaptation of Chinese students in the Netherlands     

LONG Jian-hua YAN Wen-hua YANG Hua-dong Jan Pieter van Oudenhoven 《美中教育评论》2009,6(9):1-8,51

This study investigates the influence of demographic and academic variables, intercultural communication self-efficacy, and multicultural personality dimensions on cross-cultural adaptation of Chinese students （N=168） who have stayed for a couple of months in the Netherlands. The results indicate that different personality dimensions have more or less predictive power depending on the aspects of cross-cultural adaptation. Specifically, emotional stability appears to be a positive predictor for academic performance, psychological well-being, and a negative predictor for experienced difficulties, whereas cultural empathy, open-mindedness and social initiative are more important predictors for indicators of social adjustment, such as having friends and receiving social support. Intercultural communication self-efficacy is related to higher academic performance, fewer experienced difficulties, and more satisfaction with life. In addition, a remarkable finding is that women do better than men do on academic performance, receive more social support and are more satisfied with their lives.  相似文献   

The Contribution of Trade Books to Early Science Literacy: In and Out of School     

Meadow Schroeder  Anne Mckeough  Susan Graham  Hayli Stock  Gay Bisanz 《Research in Science Education》2009,39(2):231-250

Lifelong science literacy begins with attitudes and interests established early in childhood. The use of trade books (i.e., a literary work intended for sale to the general public) in North American school classrooms to support the development of science literacy invites an examination of the quality of science content disseminated to students. A total of 116 trade books were examined to: (a) determine the degree to which science trade books complement expected science knowledge outcomes outlined in school curricula, and (b) compare trade book content to the goals of scientific literacy. Analysis across four science topics, Dinosaurs, Space, Inheritance, and Growth and Life Properties, revealed that this body of children’s literature is inconsistent in its coverage of curricular goals and elements of scientific literacy. Because trade books represent children’s first exposure to science, these shortcomings should be addressed if these books are to be maximally effective in promoting science literacy. Implications for using trade books in the classroom are discussed.

The effects of contingent feedback on perceived control and performance     

Frans Siero  Jan Pieter van Oudenhoven 《European Journal of Psychology of Education - EJPE》1995,10(1):13-24

The purpose of this study was to examine the impact on students’ performance of three contingent feedback strategies used by teachers. Contigency means that the feedback strongly corresponds with task behaviour that can be controlled by the students. Elementary school students (N=296) received individualized feedback about their performance during a series of five lessons. Within this contingent feedback structure, three strategies were applied which were assumed to enhance the perceived controllability of the task situation: (1) enhancing the perceptibility of the contingency between feedback and task behavior; (2) explicit reference to effort as part of the feedback, and (3) setting of goals. As predicted, the three contingent feedback strategies had a significant positive effect on perceived controllability, and led to better task performance.  相似文献

Showing results? An analysis of the perceptions of internal and external stakeholders of the public performance communication by the Belgian and Dutch Railways     

Dave Gelders  Mirjam Galetzka  Jan Pieter Verckens  Erwin Seydel 《Government Information Quarterly》2008

Performance measurement and communicating about it with the broader public is not self-evident if one looks at public services organizations (Hernon, P., 1998. The government performance and results act. Government Information Quarterly, 15: 153–156). In Belgium and the Netherlands, one organization that has been under constant surveillance from its stakeholders is the railroad company. Originally a national public service, it has changed through a European directive to operate in a liberalized transportation market. In this paper, we present the results of a qualitative study into what the Belgian and Dutch railway companies measure about their performance towards travelers, how they measure it, and specifically how they communicate it to their employees and stakeholders. Although we might expect the Dutch railway company (NS) to be more transparent than the Belgian railway company (NMBS/SNCB), in reality the two organizations do not differ that much from each other.  相似文献   

Identification of visual dimensions in photographs using multidimensional scaling techniques     

Marina Stock Mclsaac  Mary Lou Mosley  Naomi Story 《Educational technology research and development : ETR & D》1984,32(3):169-179

An examination of underlying visual dimensions commonly perceived in photographs was conducted using multidimensional scaling techniques. Fifteen male and female university graduate students individually examined 34 photographs chosen to represent a broad range of visual topics. Similarity judgments between photographs were used for multidimensional scaling, while subject interview data were used to describe meaningful visual concepts. Results indicate that pictures were grouped in clusters along three observable dimensions. Life, nature, and culture emerged as the dimensions of primary importance to viewers. This suggests the existence of universal meaning systems in visuals for communicating denotative and connotative meaning and presents experimental variables for future hypothesis testing. We gratefully acknowledge David Lancy’s inspiration and Ed Greenberg’s significant contribution to this work.  相似文献
