Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
No full textWe 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
PAT Science : getting good assessment down pat
No full textA new school assessment resource in science from the Australian Council for Educational Research (ACER) has just been launched, following more than two years of development and trial testing. Called PAT Science, the new addition to the Progressive Achievement Tests series complements PAT Reading and PAT Maths, which are now widely used in Australian schools. PAT Science fills an identified need for better classroom information about the progress students make in their science learning between Year 3 and Year 10. By the time they reach 15 years of age, 13 percent of Australian students are classified as \u27at risk\u27 of not having the basic levels of scientific understanding required to function in adult society, according to PISA 2006. Australia also has fewer high-achieving students than many other countries in our region, according to TIMSS 2007. PAT Science provides teachers and schools with information about students\u27 levels of achievement of the concepts, skills and processes of science and a basis for monitoring individual progress. There are eight science tests of increasing difficulty for use in Years 3 to 10 and the tests have no common items. Each test is appropriate for and normed on, two or three year levels. Although the first edition of PAT Science predates the introduction of the national curriculum, it has been informed by the National Curriculum Board\u27s 2008 \u27National Science Curriculum Framing Paper\u27.

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
Assessment: Getting to the Essence
No full textThe author argues that assessment in education has become over-conceptualised and overcomplicated, and assessment concepts and terminology introduced over the past half century sometimes now function as impediments to clear thinking and good practice. The one fundamental purpose of assessment in education, he says, is to establish and understand where learners are in an aspect of their learning at the time of assessment. When this is recognised, many supposedly important distinctions become less significant. Currently, however, such distinctions tend to result in fragmentation of the field, with proponents championing one assessment purpose or method while denigrating others. He explains why advances in assessment theory and practice require a more unified conceptualisation
