Beyond Lesson Studies and Design Experiments: Using theoretical tools in practice and finding out how they work
Full text linkThis paper aims to illustrate how fruitful insights into the link between school teaching practice and student learning outcomes can be theoretically grounded by the variation theory from the field of phenomenography; and from this framework demonstrate how a 'pedagogy of awareness' can be implemented in the classroom. In this study, five teachers and 162 students at Primary Four level of school education in Hong Kong participated and the practice of the 'learning study' was adopted. By comparing the results of pre- and posttests, a significant gain was observed in the students learning outcomes.
3D Modeling of Real Artistic Objects with Limited Computer Resources
No full textModeling real life objects, although at reach of current technology, is confined to a niche of sophisticated industrial applications
because the high equipment costs involved. The costs of 3D imaging devices are substantially coming down, furthermore 3D
modeling, within certain object complexities, is becoming feasible with limited (and inexpensive) computer resources.
This work reports on modeling complex real life objects with small computer resources. Practical provisions and clear examples of
the object complexity at reach of the resources of this league are presented. Our considerations hold general validity but are
demonstrated by examples pertaining to the field of artistic objects. This area is representative of both the typical difficulties
encountered in practical 3D modeling and of the great opportunities offered by these techniques once production costs will be
substantially lowered
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Problems with competence assessment as it applies to student nurses
Full text linkNursing has enthusiastically embraced the concept of continuing competence as the key means of reassuring the public of the overall quality of the profession. There are many definitions of competence and a number of nursing regulatory bodies have put into operation, a definition which is reductionist rather then holistic in nature. Not surprisingly, and as a consequence many nurses, including nurse educators, think competence comprises a number of key competencies which can be isolated, accumulated and tallied. It is clear that both philosophically and practically these notions of competence have influenced the way that student nurses are currently educated. More specifically it is in preparation for their initial entry to practice that the approach to competence assessment of student nurses becomes problematic. In this paper it will be argued that the principles of continuing competence assessment, associated with the on going competence of experienced registered nurses, do not readily translate to students who are still in the process of learning. We suggest that solutions to this problem are three-fold and can be found by replicating for the student the conditions that apply to the assessment of continuing competence for registered nurses
