Projections de mortalité par cause de décès : Extrapolation tendancielle ou modèle âge-période-cohorte
No full textBurgio (Alessandra), Frova (Luisa). - Mortality Projections by Causes of Death, Extrapolation of Trends, or Age-Period-Cohort Models An age-cohort model is used to project mortality from specific causes and the results are compared with those from a more determinist method of analyzing times series, based on an adjustment of period data by analytic functions. This method is applied to Italian statistics for those aged 60 and older. In this population neoplasms and cardio-vascular disease are important causes of death. The mortality rates used for five-year groups based on age, sex, and cause of death were supplied by WHO for 1951-1986. First, results from a projection for 1971-1986 based on death rates between 1951 and 1986 were compared with actual data. The death rate was then projected to 2020, on the basis of rates for the period 1951-1986. The results and theoritical considerations clearly show the strengths and weaknesses of the two methods of projection used.Burgio (Alessandra), Frova (Luisa). - Projections de mortalité par cause de décès : extrapolation tendancielle ou modèle âge-période-cohorte Un modèle âge-cohorte-période est utilisé pour projeter la mortalité par cause. Il est confronté à une méthode plus classique d'analyse des séries chronologiques, de type déterministe, fondée sur l'ajustement des données transversales par des fonctions analytiques. La méthode est appliquée à la mortalité en Italie au-delà de 60 ans ; les causes de décès retenues sont celles caractéristiques de ces âges cancers et maladies cardio-vascualires. On utilise les taux de mortalité par groupe quinquennal d'âge, sexe et cause de décès fournis par l'OMS pour la période 1951-1986. On a d'abord confronté à la réalité une projection pour la période 1971-1986 s'ap- puyant sur la connaissance de la mortalité des années 1951-1970. On a ensuite projeté la mortalité jusqu'en 2020 sur la base des taux de 1951-1986. Les résultats empiriques et les considérations théoriques permettent de mettre en lumière les forces et faiblesses des deux méthodes de projection.Burgio (Alessandra), Frova (Luisa). - Proyecciones de mortalidad por causa: extrapo- lación de tendencias o modelo edad-período-cohorte El articulo présenta un modelo edad-período-cohorte para proyectar la mortalidad por causa. Este modelo se compara con un método más clásico y determinista de análisis de series cronológicas, basado en el ajuste de datos transversales a través de funciones analiti- cas. El método se aplica a la mortalidad después de los 60 aňos en Italia; las causas de mortalidad consideradas son las caracteristicas de estas edades: cancer y enfermedades cardio-vasculares. El análisis se basa en las tasas de mortalidad por grupos quinquenales de edad, por sexo y por causa proporcionados por la OMS para el periodo 1951-1986. En primer lugar, las proyecciones elaboradas para el periodo 1971-1986 se comparan con la evolución observada. A continuación, en base a las tasas observadas para 1951-1986, las proyecciones se extienden hasta 2020. Los resultados empiricos y las consideraciones teóricas ponen en evidencia las venta- jas y desventajas de ambos métodos de proyección.Burgio Alessandra, Frova Luisa.

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

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.
