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
Erosion of flysch seacliffs in the French Basque Country : benefits of a typological approach of gravitational instabilities
No full textL'érosion des falaises constitue un risque pour la pérennité des populations et des infrastructures côtières. Les falaises du Pays Basque, situées dans les Pyrénées-Atlantiques (64), s'érodent à des vitesses variant du mm.an-1 au m.an-1, selon les secteurs. Actuellement, les facteurs et les instabilités prépondérants qui régissent la variabilité temporelle et spatiale du recul des falaises sont mal connus. Cette thèse considère un aspect rarement abordé dans cette thématique : les types d'instabilités gravitaires participant à l'érosion. Ce travail a entrepris de hiérarchiser les vitesses de recul des falaises en fonction des types d'instabilités gravitaires et de leurs facteurs contributifs.Dans ce but, une démarche naturaliste et quantifiée de caractérisation géologique et géomorphologique a été déployée à deux échelles spatiales. A l'échelle régionale (1 : 25 000ème), la vitesse moyenne de recul du sommet de falaise a été quantifiée par analyse de photographies aériennes (1938-2018) : elle diffère de 0.01 à 0.16 m.an- 1 selon les morphotypes de falaises, classés en fonction de leur structure et couverture géologique. L'inventaire a été actualisé par analyse du MNT et d'orthophotographies de 2018, avec 290 évènements catégorisés en 5 types d'instabilités. Environ 75% d'entre eux n'a pas contribué au recul du sommet de falaise. A l'échelle du site (1 : 2 500ème), les volumes érodés (2019-2022) ont été quantifiés par différence de surfaces issues de données lidar. Les périodes de retour ont été évaluées de 30 à plus de 80 ans par analyse de photographies aériennes et associées à différentes combinaisons d'instabilités gravitaires successives. Les facteurs géologiques et géomorphologiques contribuant aux types d'instabilités ont été hiérarchisés à partir d'observations de terrain. Ainsi, la période de retour et la vitesse de recul des falaises basques sont associées à des combinaisons d'instabilités gravitaires et de facteurs géologiques et géomorphologiques.Seacliff retreat is a hazard that threatens people and infrastructure safety in coastal areas. Basque Country seacliffs, located in Pyrénées-Atlantiques (64), France, retreats at rates varying from mm.yr-1 up to m.yr-1 according to spatial areas. Presently, the factors and phenomena controlling the temporal and spatial variability of seacliff erosion are not well known. This PhD considers an angle that is seldom approached in this field: the different instability types contributing to erosion. Thus, this work aimed to hierarchize seacliff retreat rates according to instability types and their contributing factors.For this purpose, a naturalistic and quantified approach has been applied on two spatial scales, to characterize geology and geomorphology. At regional scale (1:25 000 m), the mean top cliff retreat rate was assessed by analysing aerial photographs (1938-2018): it varies from 0.01 up to 0.16 m.yr-1 depending on the seacliffs morphotypes classified according to their geological structure and cover. The inventory was updated by analysing DEM and orthophotographs from 2018, with 290 events categorized in 5 instability types. About 75% of these phenomena did not contribute to the top cliff retreat. At site scale (1:2 500 m), the volumes eroded (2019-2022) were quantified by the difference of surfaces produced by lidar point clouds. Analysis of archival and recent aerial photographs revealed return periods of top cliff retreat range from 30 to over 80 years and are attributable to combinations of different instability types triggered successively. Geological and geomorphological factors contributing to instability types were hierarchized, based on field observations. Therefore, return period and retreat rates of Basque seacliffs are linked to combinations of gravitational instabilities and geological and geomorphological factors
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.
