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
Contraintes ventilatoires à l'exercice chez l'obèse (effets de l'entraînement)
No full textLes principales complications respiratoires de l obésité sont une demande accrue de ventilation, une augmentation du travail respiratoire, l inefficacité des muscles respiratoires et une diminution de la compliance respiratoire. Ces personnes présentent également une aggravation de la dyspnée et une diminution de la capacité d effort, éléments essentiels à la qualité de vie. Notre étude montre une que l exercice physique induit l installation de contraintes ventilatoires caractérisé par une augmentation du travail respiratoire, diminution de la force des muscles inspiratoires, altération de la performance des muscles inspiratoire, une dyspnée d effort et une distension pulmonaire dynamique à l exercice physique. Ces résultats sont donc en faveur de l existence d un cercle vicieux du déconditionnement chez ces sujets et ce d autant plus que leur activité physique était corrélé à leur tolérance à l effort. Ces observations justifient ainsi la prescription d un réentraînement pour améliorer la tolérance à l effort et la qualité de vie des sujets obèses. Nous avons montrés que le réentraînement à l effort améliore la tolérance à l effort, la performance des muscles inspiratoires et diminue la dyspnée d effort. En conclusion, les sujets obèses présentent des contraintes ventilatoires à l exercice constituant un facteur limitant à l exercice, le réentraînement à l effort chez les obèses constitue un traitement pertinent pour améliorer la tolérance à l effort et la qualité de vie des sujets obèses et permettre ainsi de freiner l évolution de la maladie vers l invalidité et le handicap psychosocialThe major respiratory complications of obesity include a heightened demand for ventilation, elevated work of breathing, respiratory muscle inefficiency and diminished respiratory compliance. Obese patients have increased dyspnoea and decreased exercise capacity, which are vital to quality of life. Our study shows that physical exercise is accompanied by an increased work of breathing, weakness of the inspiratory muscles, alteration of the inspiratory muscle performance, dyspnea of and a dynamic hyperinflation. Thus, these results are in favor of the existence of a vicious circle of deconditioning in these subjects and particularly as their physical activity were correlated with their exercise tolerance. These observations justify the prescription of endurance training to obese subjects to improve the exercise tolerance and the quality of life. Our results demonstrate that training improves exercise tolerance, performance of the inspiratory muscles and decrease dyspnoea. In conclusion, the obese subject present ventilatory constraints during exercise constituting a limitant factor to exercise, training improve exercise tolerance and the quality of life inducing a possible slow down to the evolution of the disease towards disability and psychosocial handicap in obese subjectsAMIENS-BU Lettres (800212104) / SudocSudocFranceF
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
