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
Étude des adaptations spécifiques à la pratique des activités d’armer : facteurs de risque et prévention des pathologies de l’épaule
No full textCette thèse a été réalisée en co-tutelle entre l'université Claude Bernard Lyon 1 et l'Université de Montréal. Ce projet a été soutenu par les programmes explora'doc de la région Rhône-Alpes et globalink de Mitacs.Le complexe articulaire de l’épaule est extrêmement sollicité au cours de la pratique du tennis. Le service, notamment, impose des contraintes mécaniques importantes et requiert des positions articulaires extrêmes plaçant l’épaule dans des situations à risque de blessures. La pratique intensive du tennis conduit à des adaptations musculo-squelettiques et fonctionnelles qui seraient bénéfiques à la performance. Cependant, il est difficile de savoir quand elles deviennent excessives ou déséquilibrées ce qui augmenterait les risques de blessures. Alors que la détection des futurs talents commence dès 5-6 ans, peu d’informations sur les caractéristiques de leur épaule, des facteurs de risque de blessures et de la pathomécanique spécifique sont actuellement disponibles. De telles connaissances seraient utiles pour optimiser leur prise en charge par les entraîneurs. L’objectif de ce travail de thèse était de caractériser l’épaule du jeune joueur de tennis, d’identifier des facteurs de risque de blessures et décrire la pathomécanique de l’épaule en lien avec le service du tennis.
Afin de caractériser l’épaule du jeune joueur de tennis, 67 joueurs de tennis asymptomatiques âgés de 7 à 13 ans ont été répartis en trois groupes en fonction de leur âge biologique. En comparant les amplitudes articulaires et les forces des muscles de l’épaule, il a été observé que ces caractéristiques musculo-squelettiques s’adaptaient dès le plus jeune. Par la suite, afin d’identifier des facteurs de risque de blessures à l’épaule, ces mêmes caractéristiques ont été comparées entre 31 joueurs avec antécédent de douleur et 60 joueurs asymptomatiques. Les joueurs avec antécédent de douleur présentaient une plus grande amplitude de rotation de l’articulation glénohumérale ainsi qu’une faiblesse des muscles rotateurs externes de l’articulation glénohumérale et des muscles fixateurs de la scapula. Cependant, il restait difficile de savoir si ces maladaptations étaient la cause ou la conséquence de la blessure à l’épaule. Un suivi longitudinal par les analyses de transitions des profils latents a été réalisé pour apporter un éclairage. Par ailleurs, afin de mieux décrire la pathomécanique de l’épaule en lien avec le service, la cinématique des articulations glénohumérale et scapulothoracique enregistrée lors du service a été comparée entre 13 joueurs sans antécédent de douleur et 15 avec antécédent de douleur. Ces joueurs avec antécédent de douleur modifiaient leur cinématique glénohumérale et scapulothoracique à la fin de la phase d’armer du service afin probablement d’éviter la douleur et de poursuivre leur pratique du tennis. Enfin, l’étude précédente a été complétée par une analyse biomécanique du service avant et après affaiblissement du trapèze inférieur par fatigue avec électrostimulation. La faiblesse des fixateurs de la scapula, décrite chez des joueurs avec antécédent de douleur, conduisait à une cinématique scapulaire inappropriée et une diminution d’activation des muscles antérieurs de l’épaule pouvant mettre en péril les structures anatomiques du complexe articulaire de l’épaule.
Ces résultats apportent des informations essentielles pour améliorer la qualité des entraînements et la prévention des blessures à l’épaule chez les jeunes joueurs de tennis. Ils soulignent notamment l’importance d’un travail de renforcement des muscles stabilisateurs de l’épaule (muscles rotateurs de l’articulation glénohumérale et stabilisateurs de la scapula).The shoulder joint complex is largely involved in the tennis strokes. Particularly, the tennis serve applies high mechanical constraints and requires extreme joint positions making the shoulder vulnerable to injuries. Intensive tennis practice leads to musculoskeletal and functional adaptations that are thought to be beneficial to performance. However, it remains unclear when they become unbalanced or excessive that increases the risk of injury. The prospects are scouted from 5 years old, but little is known on their specific shoulder characteristics, risk factors for injury and pathomechanics. Such knowledge would be useful to optimize their monitoring by coaches. This thesis aimed to characterize the young tennis player's shoulder, identify risk factors for injury and describe the shoulder pathomechanisms related to the tennis serve.
To characterize the young tennis player’s shoulder, 67 asymptomatic tennis players aged 7 to 13 years old were divided into three groups according to their biological age. The comparison between our three groups highlighted that the glenohumeral ranges of motion and the shoulder muscle strength adaptions occurred from an early age. Then to bring risk factor for shoulder injuries to light, these parameters were also compared between 31 players with a history of shoulder pain and 60 asymptomatic players. Players with a history of shoulder pain presented a larger glenohumeral joint total rotation range of motion as well as a weakness of the glenohumeral external rotator muscles and the scapular stabilizer muscles. A longitudinal study, using a latent profile transition analysis, was conducted to determine whether the factors previously identified were the cause or consequence of the shoulder injury. Furthermore, in the aim to describe the shoulder pathomechanisms related to the tennis serve motion, the glenohumeral and scapulothoracic kinematics of the tennis serve were compared between 13 players without and 15 with a history of shoulder pain. Players with a history of shoulder pain adapted their glenohumeral and scapulothoracic kinematics at the end of the cocking phase to probably preserve the sub-acromial space and the rotator cuff tendons during the tennis serve. Finally, the previous study was completed by a study analyzing the shoulder biomechanics of a tennis serve before and after the fatigue of the lower trapezius. The weakness of the scapular stabilizer muscles impaired the scapular kinematics and decreased the activation of the anterior shoulder muscles that may jeopardize the shoulder joint anatomical structures.
These findings bring new knowledge to improve the young players monitoring and the injury prevention. Particularly, it highlights the importance to strengthen the stabilizer muscles (glenohumeral external rotator muscles and scapular stabilizer muscles)
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
