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
Inflammatory markers, physical fitness, and pain in children
No full textThe current pediatric obesity epidemic is associated with increased clinical pain; the relation between pain and obesity is not clear but a potential mechanism is inflammation. Obesity is a chronic pro-inflammatory state associated with risk for metabolic syndrome, diabetes and cardiovascular disease. Furthermore, inflammatory markers contribute to the development and modulation of pain. Exercise, a hallmark of obesity interventions, is often prescribed for pain management. Pain relief after exercise, exercise induced hypoalgesia (EIH), may be a critical pain management strategy for overweight/obese adolescents, but it is unknown if EIH exists in adolescents. Moreover, mechanisms for EIH are not established; the concept of conditioned pain modulation (CPM), ‘pain inhibits pain,’ is a possible central component of pain relief after exercise through endogenous pain inhibition. In adolescents across weight status, experimental pain was assessed at baseline, in a CPM protocol, and pre/post maximal aerobic exercise (EIH). Clinical pain, psychosocial parameters, physical fitness, physical activity levels, body composition, and health status were also measured. In this community sample, normal weight and overweight/obese adolescents did not report clinically significant differences in clinical/experimental pain. Adolescents with higher BMI and central adiposity demonstrated elevated inflammation and metabolic syndrome severity but decreased quality of life. Fit overweight/obese adolescents demonstrated higher quality of life and decreased metabolic syndrome severity but similar inflammation and pain. Adolescents experienced EIH regardless of weight status, physical activity, and physical fitness; EIH was positively associated with lean mass. CPM was similar between weight status and sex; lean mass uniquely predicted the CPM magnitude. CPM and EIH are mildly associated but further pediatric research is warranted. These results suggest that adolescents of overweight/obese status experienced increased metabolic syndrome severity but not necessarily clinical pain; physical fitness circumvented metabolic syndrome severity. Aerobic exercise may be utilized for pain relief in adolescents across weight status. Endogenous pain modulation may be a possible mechanism of pain relief after exercise, but pain with exercise is not required for pain relief after exercise. Assessment of EIH and CPM in pediatric populations may help guide and tailor unique interventions to assist with pain management across the weight spectrum
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
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
