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
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
Characterization of decision-making under fluctuating time pressure in an ecological context : mixed methods and decision approaches applied in competitive esports context.
No full textCe travail étudie l’influence d’une pression temporelle (PT) fluctuante sur les processus décisionnels lors de situations écologiques de compétition esportives (i.e. jeu vidéo compétitif). Ce projet nécessite d’opérationnaliser le contexte spatio-temporel (ST) de décision au regard de la PT et d’associer les processus cognitifs à des configurations ST typiques.L’étude s’appuie sur trois variables indépendantes (i.e. niveau d’expertise, type de séquence de jeu, processus décisionnel Recognition-Primed Decision-Making (Klein, 2008)) et onze variables dépendantes relatives à des données ST (i.e. durée de séquence, instants de décision, densité spatiale), d’encéphalographie (i.e. densités spectrales cérébrales), de variabilité cardiaque et de conductance dermale.Les meneurs de jeu de quatre équipes esportives ont été étudiés au cours de 24 parties suivies d’entretiens d’autoconfrontation. Au total, 474 décisions sont identifiées et associées à 148 séquences typiques de jeu.Deux séquences ST typiques de jeu sont caractérisées et opérationnalisées au regard de la PT. L’indicateur de densité spatiale est proposé pour mesurer la PT.Les résultats suggèrent que les séquences de forte PT engagent chez les joueurs une proportion supérieure de décisions rapides, intuitives, réalisées sans étudier d’alternative, une augmentation du recours aux ressources cognitives, un rappel volontaire d’informations stockées en mémoire et un filtrage d’informations perçues. Les séquences de faible PT sont associées à une activité visuo-spatiale accrue.Les joueurs au niveau de pratique le plus élevé montrent une allocation de ressources cognitives supérieure dédiée au calcul mental, à l’utilisation de la mémoire de travail ainsi qu’à l’attention visuo-spatiale. Ils semblent adopter une stratégie d’approche face aux situations stressantes et témoignent d’un niveau d’activation physiologique plus élevé et plus tôt avant l’immersion en situations de forte PT.This work investigates the influence of fluctuating time pressure (TP) on decision-making processes during ecological situations of esports competition (i.e., competitive video gaming). This project requires operationalizing the spatio-temporal (ST) decision context with regard to TP and associating cognitive processes with typical ST configurations.The study is based on three independent variables (i.e., level of expertise, type of game sequence, Recognition-Primed Decision-Making process (Klein, 2008)) and eleven dependent variables relating to ST data (i.e., sequence, instants of decision, spatial density), encephalography (i.e., cerebral spectral densities), cardiac variability and dermal conductance. The playmakers of four esports teams were studied during 24 games followed by self-confrontation interviews. A total of 474 decisions are identified and associated with 148 typical game sequences.Two typical ST sequences are characterized and operationalized with regard to PT. Spatial density indicator is proposed to measure PT. The results suggest that high PT sequences induce a higher proportion of quick, intuitive decisions made without studying any alternative, an increase in the use of cognitive resources, a voluntary recall of information stored in memory and a filtering of perceived information. Low PT sequences are associated with increased visuospatial activity.The most skilled group of players showed a higher allocation of cognitive resources dedicated to mental computation, the use of working memory as well as visuospatial attention. They seem to adopt an approach strategy in the face of stressful situations and show a higher and earlier level of physiological activation before immersion in high PT situations
Development of sportsmen's successful career of top-level : between decision-making transitional dynamics and adaptation.
No full textLes sportifs de haut niveau traversent tous des phases de transitions plus ou moins bien négociées dans leur carrière sportive, que cela soit des transitions normatives ou non normatives. Cette thèse examine la portée de ces transitions sur les processus décisionnels et adaptatifs du sportif de haut niveau qui le conduisent à effectuer un choix plutôt qu'un autre lors d'un moment clef de sa carrière (e.g. sportif, professionnel, social). Les trois études de cette thèse s'inscrivent principalement dans le cadre d'une approche développementale du déroulement de carrière des sportifs de haut niveau (Wylleman, Lavallee & Alfermann, 1999) et reposent sur le modèle du Push-Pull, Anti Push, Anti Pull (Schutz, Mullet et al, 1998). La première partie de cette thèse s'est intéressée au prolongement depuis une dizaine d'années des carrières des sportifs de haut niveau se poursuivant au-delà de l'âge de trente ans, ainsi qu'aux mécanismes sous jacents au maintien et à la protection du bien-être subjectif lié à ce phénomène. Des éléments de similarité liés à leurs caractéristiques personnelles et à leur parcours ainsi que des éléments de singularité liés au découpage et à la durée des étapes de leur carrière sont apparus. La seconde étude de cette thèse porte sur le parcours de vie des sportives d'élite et le choix de la maternité en cours de carrière sportive et/ou post carrière sportive. Les parcours se construisent au regard des significations accordées aux évènements contextuels et circonstanciels, aux aspirations et idéaux personnels, aux priorités de vie. Le choix de la maternité oscille entre le désir d'un épanouissement personnel à travers à la fois un épanouissement sportif et un épanouissement de mère et la primauté accordée à sa vie sportive de l'autre avec l'absence d'envie de procréer. La troisième étude s'est intéressée à l'entrée en pôle d'entraînement, et plus particulièrement aux éléments facilitants ou perturbants qui ont accompagné la décision des sportifs de haut niveau d'entrer ou non en pôle et qui ont participé à une adaptation plus ou moins bien réussie Les éléments qui se sont révélés importants qu'ils soient plutôt positifs ou négatifs gravitent autour du cadre de vie, du double projet, et du projet sportif.The high-level sportsmen cross all phases of transitions more or less good negotiated in their sporting career, that it's normative or not normative transitions. This thesis examines the impact of these transitions on the decision-making and adaptive processes of the high-level sportsman which lead him to make a choice rather than the other one during a key moment of its career (e.g. sportsman, professional, social). Three studies of this thesis join mainly within the framework of a développementale approach of the career development of high-level sportsmen (Wylleman, Lavallee & Alfermann, 1999) and rest on the model of Push-Pull, Anti Push, Anti Pull (Schultz, Mullet and al, 1998). The first part of this thesis was interested in the continuation since around ten years of the careers of high-level sportsmen continuing beyond the age of thirty years, as well as in mechanisms under jacents in the preservation and in the protection of the subjective well-being. Elements of similarity bound to their personal characteristics and to their route as well as elements of peculiarity bound to the cutting and to the duration of the stages of their career appeared. The second study of this thesis concerns the route of life of the sportswomen of elite and the choice of the maternity in course of career sports and/or comment sporting career. Routes build themselves towards the meanings granted to contextual and incidental events, to aspiration and ideal staffs, in the priorities of life. The choice of the maternity oscillates between desire of a self-fulfillment through at the same time a sports blooming and a blooming of mother and superiority granted to its sports life of the other one with the absence of envy to procreate. The third study was interested in entrance to pole of training, and more particularly in facilitating or disrupting elements which accompanied the decision of the high-level sportsmen to enter or not pole and which participated in a more or less good made a success adaptation The elements which showed themselves important that they are rather positive or more negative revolve around living environment, double project, and sports project
