We evaluate author impact indicators and ranking algorithms on two publication databases using large test data sets of well-established researchers. The test data consists of (1) ACM fellowship and (2) various life-time achievement awards. We also evaluate different approaches of dividing credit of papers among co-authors and analyse the impact of self-citations. Furthermore, we evaluate different graph normalisation approaches for when PageRank is computed on author citation graphs.We find that PageRank outperforms citation counts in identifying well-established researchers. This holds true when PageRank is computed on author citation graphs but also when PageRank is computed on paper graphs and paper scores are divided among co-authors. In general, the best results are obtained when co-authors receive an equal share of a paper's score, independent of which impact indicator is used to compute paper scores. The results also show that removing author self-citations improves the results of most ranking metrics. Lastly, we find that it is more important to personalise the PageRank algorithm appropriately on the paper level than deciding whether to include or exclude self-citations. However, on the author level, we find that author graph normalisation is more important than personalisation. 相似文献

Faced with the growing number of case studies in contemporary art, philosophy provides conservators with a series of conceptual tools that allow to theorize their practice. The notion of intentionality and attentionality borrowed from Genette enables a better understanding of the problems that Dirty Corner by Anish Kapoor (a work vandalized on many occasions) poses. I will show that the conservator deals with the issue of the identity of a contemporary work in a different way from the art historian, and that philosophy is a practical tool to understand the specificity of the former's approach and intervention. 相似文献

The clinical use of motivational messages: an inquiry into the validity of the ARCS model of motivational design 总被引:2,自引:0,他引:2
Instruction, even when prepared according to sound instructional design principles, often does not stimulate students' motivation to learn. A motivational intervention, developed according to the processes outlined inthe ARCS model of motivational design, was implemented and tested following the conventions of an embedded single-case study. It was tested with a group of 15 adults participating in a staff development course conducted within the Mozambique Ministry of Education. Results, based on concurrent and discriminant analysis of both quantitative and qualitative data, indicated that the primary treatment, motivational messages, had positive effects on student attitude and performance. It may be concluded that the specific intervention and the ARCS model which provided the basis for designing it provide a sound basis for positively influencing student motivation to learn. 相似文献

Lifelong Debt: Rates of Return to Mature Study 总被引:2,自引:0,他引:2
High rates of return to first degrees have been used to justify increased student financial contributions to higher education. However, no discrete study of rates of return to mature graduates has been carried out although mature graduates now form a significant proportion of the student population. The General Household Survey 1983–1992 was used to examine the earnings of mature graduates compared with those of matriculates. The GHS yielded 616 mature graduate men in full-time work and 296 mature graduate women who were in full-time employment. It was found that the rate of return to mature male graduates was just above one per cent. With recent added costs, new male mature graduates can be forecast to make a sizeable loss on their study. Rates of return to women mature graduates were higher, between five and six per cent, and, based on these figures, the recent increased cost of mature graduate study should be covered by increased earnings. However, these calculations are based on average earnings for the modal age cohort of mature graduates. Those who are older when they complete or earn below the average (a large percentage) will not recoup the costs of study. 相似文献

Abstract Using an experiential case approach, this study explores the conventional wisdom that distance education courses require greater faculty work effort and time commitment than traditionally taught courses. The study's basis for analysis is an instructor's time and effort in developing and delivering a graduate‐level course in public administration, for both a distance course (a modality with which he had no previous experience) and his traditional classroom courses. The study finds support for the conventional wisdom. But it also suggests hypotheses for future comparative analysis that development and delivery time and effort may partially depend on the accumulation of instructor experience and the level of institutional support. This article also identifies some implications for future research and faculty participation in distance education. 相似文献
