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
L’âge de début de consommation de cannabis et les problèmes associés : le rôle médiateur des différents profils de consommation
Full text linkContexte. Il est bien établi dans la littérature qu’un âge de début de consommation de cannabis (ADCC) précoce est associé à un risque accru de développer des problèmes liés à la consommation de cannabis (CC). Toutefois, les mécanismes sous-jacents à cette relation demeurent peu étudiés. Objectifs. C’est dans cette optique que le présent projet vise à examiner les différents profils individuels et les facteurs contextuels associés à la CC à l’adolescence et au début de l’âge adulte, en tenant compte de la fréquence, de la quantité, des motifs et des contextes sociaux de CC. De plus, l’étude cherche à mieux comprendre le lien entre l’ADCC et le développement de problèmes liés à la CC en explorant le rôle médiateur des profils de CC. Méthodes. L’échantillon est composé de 215 enfants nés en 1996-1997, suivis jusqu’à l’âge adulte (26 ans). Il provient de la première cohorte de l’Étude longitudinale du développement des enfants du Québec (ELDEQ-CI; En 2001… j’avais 5 ans!). Pour la présente étude, les données longitudinales des participants âgés de 13 à 25 ans ont été analysées. Des analyses de profils latents ont d’abord permis d’identifier les profils de CC à partir de la fréquence, de la quantité, des motifs et du contexte social. Ensuite, des analyses de trajectoires (effets directs) ont été réalisées pour évaluer les associations entre l’ADCC et les problèmes liés à la CC. Finalement, des analyses de médiation (effets indirects) ont été conduites afin d’examiner le rôle médiateur des profils de CC dans la relation entre l’ADCC et les problèmes liés à la CC. Résultats. Quatre profils distincts ont été identifiés : 1)non-utilisateurs (n=91), 2)Haute fréquence + Faible quantité + Partenaire (n=24), 3)Normatif + Social (n=45), 4)Haute CC + Solitaire (n=27). Les résultats indiquent que l’ADCC est significativement et négativement associé aux problèmes liés à la CC, suggérant qu’un début plus tardif est lié à une CC moins problématique. De plus, le 4e profil de consommation (Haute CC + Solitaire) médie partiellement cette relation, expliquant environ 70 % de l’association observée. Conclusion. En plus de répliquer les résultats d’études antérieures démontrant qu’un ADCC précoce accroît les risques de développer des problèmes liés à la CC, les analyses réalisées dans le cadre de cette étude ont permis d’identifier des profils présentant des niveaux de risque différents. Les résultats de notre étude soulignent ainsi l’importance de développer des activités de prévention qui misent sur le retardement de l’ADCC, mais également d’implanter des interventions adaptées aux profils et aux risques qui y sont associés.Context. It is well established in the literature that an early age of onset of cannabis use (AOCU) is associated with an increased risk of developing cannabis use (CU) problems. However, the mechanisms underlying this association remain not yet well understood. Objectives. This project aims to examine the individual profiles and contextual factors associated with CU during adolescence and early adulthood, taking into account frequency, quantity, motives, and social contexts of CU. Additionally, the study seeks to better understand the link between AOCU and the development of CU problems by exploring the mediating role of CU profiles. Methods. The sample consists of 215 children born in 1996–1997, followed into adulthood (age 26), and drawn from the first cohort of the Quebec Longitudinal Study of Child Development (QLSCD-CI; In 2001… I was 5 years old!). Longitudinal data spanning ages 13 to 25 were analyzed. Latent profile analyses were first conducted to identify CU profiles based on frequency, quantity, motives, and social context. Trajectory analyses (direct effects) were then performed to assess associations between AOCU and CU problems. Finally, mediation analyses (indirect effects) were conducted to examine the mediating role of CU profiles in the relationship between AOCU and CU problems. Results. Four distinct profiles were identified: non-users (n=91), High freq + Low quan + Partner (n=24), Normative + Social (n=45), and High CU + Alone (n=27). Results indicate that AOCU is significantly and negatively associated with CU problems, suggesting that later initiation is linked to less problematic use. Furthermore, the High CU + Alone profile partially mediates this relationship, accounting for approximately 70% of the observed association. Conclusion. In addition to replicating previous findings that early AOCU increases the risk of developing CU problems, this study identified profiles with varying levels of risk. Our results highlight the importance of developing prevention strategies that focus on delaying AOCU, as well as implementing interventions tailored to specific CU profiles and associated risks
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
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.
