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
Borréliose de Lyme : de l’exposition aux formes graves en France : quelles données pour appréhender l’épidémiologie de la Borréliose de Lyme en France ?
No full textLyne Borreliosis (LB) is the most common vector-borne infectious disease in France. Specific knowledge about the risk of transmission to humans of agents carried by ticks are still needed. Epidemiological data at each stage of the infection cycle (tick exposure, tick bites, infection, disease...) are needed to accurately estimate its incidence, assess trends, identify geographical areas and at risk populations and guide the prioritization of public health resources for LB prevention and control.The aim of this thesis will be to quantify the exposure to tick bites and tick-borne pathogens and to evaluate the validity of the PMSI as surveillance system for hospitalized LB cases.A third of the population residing in metropolitan France stated that they had already been bitten by a tick during their lifetime and a quarter felt exposed to tick bites In rural and high incidence areas of BL, these proportions were higher.. An increase knowledge and application of preventive measures was observed between 2016 and 2019. High Borrelia burgdorferi sl seroprevalence among forestry workers of the northern half of France, particularly in the east, has been estimated. Data from PMSI have been shown to be useful for surveillance of disseminated LB cases.This thesis work bring new knowledge for operational purposes in public health, or to deepen it, on the epidemiology of Lyme borreliosis in France.La borréliose de Lyme (BL) est la plus fréquente des maladies à transmission vectorielle en France. Le besoin de connaissances précises sur le risque de transmission à l’homme des agents transportés par les tiques soulève toujours de nombreuses questions. Des données épidémiologiques à chaque étape du cycle de l’infection (exposition aux tiques, piqures, infection, maladie clinique…) sont nécessaires pour estimer précisément son incidence, évaluer les tendances, identifier les zones géographiques et les populations à risque et orienter la priorisation des ressources de santé publique pour la prévention et le contrôle de la BL. L’objectif de cette thèse est de quantifier l’exposition aux piqures de tiques, et aux agents pathogènes transmis par des tiques et d’évaluer la validité du système de surveillance des cas hospitalisés pour la borréliose de Lyme.Près d’un tiers de la population résidant en France métropolitaine déclarait avoir déjà été piquée par une tique au cours de la vie et un quart se sentait exposé aux piqûres de tiques. Dans les zones rurales et de haute incidence de la BL, ces proportions étaient plus élevées. Une augmentation des connaissances et de l’application des mesures de prévention a été observée entre 2016 et 2019. Une séroprévalence à Borrelia burgdorferi sl importante parmi les travailleurs forestiers de la moitié nord de la France, notamment dans l’Est, a été estimée. Les données issues du PMSI, ont été montrées comme utile pour la surveillance des cas BL présentant des formes disséminéesCe travail de thèse a permis d’amener des connaissances nouvelles à visée opérationnelle en santé publique, ou de les approfondir, sur l’épidémiologie de la Borréliose de Lyme en France
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
