Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Towards Digital Psychiatry in Adult Attention-Deficit/Hyperactivity Disorder : A Series of Clinical Intervention Studies using Mobile Health Applications and Virtual Reality
Get PDFThe field of digital psychiatry and psychotherapy has generated increasing interest given its potential to improve mental health care, for instance, by enhancing accessibility, scalability, and cost-effectiveness. In particular for heterogeneous disorders such as adult attention-deficit/hyperactivity disorder (ADHD), providing a large number of affected individuals early access to treatments with high personalization potential holds promise. In this project, digital psychoeducation and a novel attention training based on eye-tracking in virtual reality were evaluated in three separate clinical trials to determine their efficacy for the treatment of adult ADHD. The first study aimed to evaluate a newly developed psychoeducation smartphone application (app) in a randomized controlled trial. To this end, 60 adults with ADHD were assigned to psychoeducation groups supported by either the smartphone app or traditional paper-based brochures. After eight weekly one-hour group sessions and additional homework, a significant reduction in the primary outcome measure, observer-rated ADHD symptom severity, was demonstrated. In addition, smartphone-based psychoeducation was found to be more effective in improving ADHD symptoms and showed higher homework compliance than brochure-based psychoeducation. The second study examined digital, self-guided psychoeducation over a three-week period in 40 participants randomized to use either an interactive chatbot or the psychoeducation app employed in the first study. Results showed significant reductions in observer- and patient-rated ADHD symptoms but no interaction effects, thereby suggesting similar efficacy. The third study investigated a novel gaze-based attention refocusing training in virtual reality in 18 adults with ADHD and 18 healthy controls under three different feedback conditions: gaze-based feedback, sham feedback, or no feedback. Although patients with ADHD showed more omission errors, higher reaction times, longer distractor-related gaze dwell times, and more head movements than healthy controls, the gaze-based feedback did not improve task performance. In conclusion, the psychoeducation studies provided initial clinical evidence for the efficacy of digital psychoeducation and revealed no safety concerns. Specifically, the finding from the first study that a psychoeducation app is superior to traditional paper-based materials in supporting clinical psychoeducation indicate the applicability of the digital format. Despite symptom improvements under both intervention types in the second study, further research is needed on the use of self-guided digital psychoeducation, particularly in the case of patient interaction with a chatbot. Regarding the use of virtual reality for the potential treatment of adults with ADHD, a single-session investigation of a novel gaze-based attention refocusing training in virtual reality did not result in immediate improvements in attention performance, but showed potential in the multimodal registration of ADHD symptoms. Results suggest that further refinement of the system could lead to improved outcomes in a future multisession treatment trial

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
