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
Door lezen de wereld ontdekken: Natuur & Techniek als functionele context voor tekststructuuronderwijs
No full textWhat are the ingredients of effective reading instruction? And how can students be encouraged to apply their newly acquired reading skills in contexts outside language arts? These and other questions are at the heart of current debates about reading instruction in Dutch primary education. Schools increasingly take a thematic approach, or take a functional approach to reading comprehension instruction by integrated it into content area lessons. Still, focused instruction remains important, especially about the structure of informational texts. In the Netherlands, text structure instruction receives little attention, while it is known that insight into the coherence of texts is crucial for deep text comprehension.
This study provides insight into the viability of integrating text structure instruction with science education. Through a materials analysis, we first investigated the extent to which current teaching materials from science teaching programs are usable for text structure instruction. This analysis shows that many science topics certainly offer starting points for text structure instruction. However, the range of clearly structured texts that can serve as model texts is not sufficient for this purpose. This also holds for the science assignments that help students understand these text structures.
During design-based research, conducted in collaboration with primary school teachers, several lesson series were designed and tested in which such an integrated approach was applied. These lesson series proved to be easy to implement, and also ensured that students engaged enthusiastically. The application of the underlying design principles, however, requires professionalization of teachers, including an increase in their knowledge of text structure.
The fact that teachers show a lack of knowledge about text structure, is not surprising. An analysis of the Dutch Language Knowledge Base for students in teacher training for primary education shows that prospective teachers are provided with little theory on text structure, and that this theory is also offered in a fragmented and incomplete way.
From a quasi-experimental effect study in which working with the developed teaching materials (with attention to text structure) was compared to an integrated approach without attention to text structure, no difference in effect on reading and writing skills could be established. However, this was a relatively short intervention, in which the quality of implementation was not always optimal, and teachers in the control condition sometimes allocated more time to reading instruction than teachers in the text structure condition.
Finally, a series of educational videos on text structure and text comprehension were developed and tested among second year pre-service students. Unfortunately, a lockdown during the corona pandemic caused unforeseen circumstances during the intervention. We could show no effect of students' video viewing time on scores on a knowledge test on text structure and text comprehension, but students who had watched the videos were found to be better able to determine the structure of a self-selected reading text
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
