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
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
Trois essais empiriques sur l’identification de l’aléa moral en assurance
No full textL’aléa moral est une source de distorsion économique. La prédiction classique dans un cadre simple est qu’une meilleure couverture conduit à un effort moindre. Cette thèse étudie dans quelle mesure cette prédiction est ou non vérifiée empiriquement dans des cadres plus complexes. Le premier chapitre s’intéresse aux absences pour raison de santé. La politique étudiée est le jour de carence pour arrêt maladie dans la fonction publique de l’Etat en France. Cette politique de remboursement moins généreuse a notamment pour but de réduire l’absentéisme. Elle conduit à une baisse de la prévalence des absences de courte durée. Mais elle conduit aussi à une hausse de la prévalence des absences de longue durée. En conséquence, la prévalence de l’ensemble des absences pour raison de santé reste inchangée. Les deux chapitres suivants s’intéressent aux systèmes de bonus-malus d’un assureur automobile irlandais. Le deuxième chapitre s’intéresse à l’introduction d’un état très protecteur : la protection à vie du bonus. Cette protection est octroyée automatiquement et gratuitement aux assurés sous des conditions restrictives d’historique de sinistre et d’ancienneté. Comparé à la situation dans laquelle cet état protecteur n’existe pas, le taux de sinistre des assurés protégés augmente, tandis que le taux de sinistre des agents non protégés diminue, dans l’espoir d’être récompensés par la protection. L’existence de la protection est à l’origine d’un transfert intertemporel. Les assurés renoncent à de l’utilité présente en exerçant un effort supérieur, afin d’être récompensés par la protection et de profiter d’une utilité future plus élevée due à un effort moindre. Le troisième chapitre étudie la réaction juste après que l’assuré est récompensé par la protection à vie du bonus. Le taux de sinistre augmente immédiatement, mais seulement quand la protection existe depuis quelque temps. Cela suggère que l'effet d'un changement incitatif dépend de sa nature, mais aussi de son contexte.Moral hazard is a source of economic distortion. The classical prediction in a simple framework is that a better coverage leads to a lower effort. This thesis studies the extent to which this prediction is empirically verified in more complex settings. The first chapter focuses on health-related absences. The policy under study is the one-day waiting period for sick leave in the French central civil service. This less generous reimbursement policy notably aims at reducing absenteeism. It leads to a decrease in the prevalence of short-term absences. But it also leads to an increase in the prevalence of long-term absences. As a result, the prevalence of all health-related absences stay unchanged. The two following chapters focus on bonus-malus systems used by an Irish car insurer. The second chapter focuses of the introduction on a highly protecting state: the lifetime bonus protection. This protection is granted automatically and freely to insurees under restrictive conditions on past claims and seniority. Compared to the situation in which this protecting state does not exist, the claims rate of protected insurees increases, but the claims rate of unprotected insurees decreases, in the hope of being rewarded with the protection. The existence of the protection induces an intertemporal transfer. Insurees waive present utility by exerting more effort, so as to be rewarded with the protection and to enjoy more future utility due to lower future effort. The third chapter studies the reaction just after the insuree is rewarded with the lifetime bonus protection. The claims rate increases immediately, but only when the protection exists for some time. This suggests that the effect of an incentive change depends on its nature, but also on its context

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.
