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
Residual dizziness after successful repositioning maneuvers for idiopathic benign paroxysmal positional vertigo.
No full textTo establish a possible causal factor for residual dizziness (RD) after successful repositioning maneuvers in patients with benign paroxysmal positional vertigo (BPPV).Ninety consecutive patients with idiopathic BPPV were treated with repositioning maneuvers, and the rate of RD was assessed as well as clinical data. Posturography and assessment of anxiety levels were performed on patients reporting RD. Results were compared with a control group of BPPV patients of the sample after repositioning maneuvers and without RD.Twenty-eight subjects (31.1\%) reported RD on the second day after successful repositioning maneuvers. The mean duration of RD was 11.6 ± 3.9 days. Patients with RD presented a higher duration of BPPV (14.1 vs. 10.9 days, p = 0.01). A correlation was demonstrated between the duration of BPPV and duration of RD (p < 0.01). Subjects with RD presented increased body sways, above all in eyes-closed conditions.RD is mainly correlated with duration of vertigo in BPPV patients. Anxiety was demonstrated to play a role in increased body sways
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
Conclusion: lessons learned from and for adult education policy research
No full textThis concluding chapter brings to synthesis and reflects on the contribution of this handbook. First, it discusses what has been learned from adult education policy research on the swing between policy continuity and change in adult learning and education. Next, it considers the challenges that adult education and learning still face worldwide in the Global North and Global South. Then, it discusses what lessons have been learned for adult education policy research in terms of theoretical and methodological advances. It concludes by pointing at three avenues for further research: 1) the interaction between political regimes and the use of adult education policy; 2) the interest on adult education policy beyond direct stakeholders; and 3) the under-researched policy actors that act as intermediary organisations or appropriate, re-interpret and/or resist adult education polic
Introduction: politics, policy and the governance of adult learning and education
No full textThis chapter sets the boundaries of the handbook in terms of the definition of key concepts such as adult learning and education, policy, policy actors and contexts. It also discusses major policy and governance trends at transnational and global levels, and how these resonate with national and local adult education and policy. Attention is paid to the constellation of actors involved in policy work in adult learning and education policy. The chapter presents the critical approach generally followed in the book, confronting and investigating important policy challenges and developments, drawing on empirical research, and using and developing meaningful and conceptual and theoretical frameworks. In addition, the chapter introduces the structure of the book, and briefly summarizes the individual chapters
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
