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
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
Geological evolution of the Bodsjö area, Central-Sweden
No full textThe area studied is situated in the Bodsjö region, 80 km south of Ostersund, central Sweden, and is part of the Svecokarelian belt of Proterozoic age.
The geology of the area (approximately 250 square kilometres) which were mapped at a scale of 1/50,000 reveals the following main rock groupes:
Meta-sediments, which include meta-arkoses, meta-quartzites, meta-pelites, meta-sub-pelites wich subordinate amounts of tuffaceous rocks, represent a shallow water sedimentation at the transition between a marine and terrestrial environment. The stratigraphic relationship between the various meta-sedimentary units as well as the original sedimentary features are completely obliterated by high grade metamorphism, migmatization and polyphased deformations. A model for the evolution of the sedimentary sequence, based on lithology, is presented and probably stratigraphic correlations with the surrounding areas are proposed.
Basic and acid metavolcanics are represented by amphibolitic and quartzo-feldspathic rocks, respectively. Their chemistry suggests that they originated in an island arc environment, basic metavolcanics being possibly an early tholeiitic series and acid metavolcanics a subsequent calc-alkaline series.
Early orogenic intrusives are composed of gabbros, granodiorites, and granites. Within this group deformed granites (augen gneiss) are the most abundant.
Late-kinematic granites form small intrusions throughout the whole area. These granites have an eutectic normative composition and may be anatectic.
The Revsund granite is represented by a typical coarse-grained porphyritic type in the northern part of the area and by numerous small intrusions and dykes of varied composition throughout the central part.
Granitic intrusions of the Bodsjö area are classified as I- or S-types. These rocks are discussed in the context of Wilson's (1980) classification of Swedish granites.
Two distinct types of dolerite are the youngest intrusive bodies of the area. The Turinge (2-pyroxenes) dolerite, forming a flat lying sheeted intrusion elongated along the main structural trend of the area, and the Jotnian (1-pyroxene) dolerite mainly represented by scattered dykes and sills.
Various contact phenomena near the Turinge dolerite are observed, producing a variety of remobilized unfoliated granites particularly within the early granites.
The type and degree of metamorphism was studied in detail within the metasedimentary rocks by petrographic and microprobe methods. It was found that the main mineralogical assemblages are :
-Cordierite-biotite-andalusite-sillimanite
-Cordierite-garnet-sillimanite-biotite
-Sillimanite-biotite
-Andalusite-biotite
Microprobe date show that the petrographic observations and calculated Fe-Mg repartition (KD value) between cordierite and biotite are closely correlated.
The sequence of prograde reactions and textural relationships observed reflects the progressive decrease in pH20 (dehydration) and the relative increase in oxygen fugacity.
The highest possible P-T conditions are deduced from the composition of cordierite at the equilibrium of the reaction :
Cordierite+K-feldspar+H20 <-> sillimanite+biotite.
The cordierite composition, within the Bodsjö area, varies between Fe 35 and Fe 40. (...)La région étudiée est située à 80 km au sud de la ville d'0stersund dans les environs du lac de "Bodsjö" (Suède centrale). Elle fait partie de la province Svécokarélienne d'âge protérozoique. Son étude fut motivée par la découverte de minéralisations d'uranium dans les roches d'origine sédimentaire.
La géologie de cette région (qui couvre environ 250 Km2) cartée à l'échelle 1: 50.000, est dominée par les roches suivantes :
Les roches métasédimentaires, comprenant: des méta-arkoses, des métaquartzites, des métapélites, des méta-subpélites avec en quantité moindre des roches épiclastiques, représentant une sédimentation de faible profondeur formant la transition entre deux environnements, marin au nord et terrestre au sud. Les relations stratigraphiques et les caractéristiques originelles des roches sédimentaires ont été complétement oblitérées par un métamorphisme de haut degré et une tectonique active.
La signification des différentes lithologies permet de proposer une évolution du paléoenvironnement qui débute par la déposition de graywackes, associés à la subsidence du bassin inter-arc, suivie de mouvements ascendants aboutissant à la formation d'arkoses dans les grabens. Finalement un environnement tectonique plus stable a permis la déposition de quartzites.
Les roches métavolcanigues, de type basique et acide, sont représentées respectivement par des amphibolites et par des gneiss quartzo-feldspathiques. Leur composition chimique indique qu'elles se sont formées dans un environnement d'arc d'îles. Ainsi les termes basiques sont supposées être l'équivalent d'une série tholéïtique primitive tandis que les termes acides représenteraient probablement une série calco-alcaline ultérieure.
Les roches primorogéniques sont composées de gabbros, de granodiorites et de granites. Des granites fortement déformés (gneiss oeillés) dont la composition normative est proche des termes potassiques de la série granitique de Hietanen, constituent la majeur partie de ce groupe.
Les granites tardi-orogéniques forment de petites intrusions réparties sur toute la région étudiée. Ces granites ont une composition normative eutectique et sont vraisemblablement d'origine anatectique.
Dans la partie nord de la région étudiée, le Revsund granite est de type porphyrique à grain grossier; au centre, on trouve de nombreuses petites intrusions et "dykes" de composition variable.
Les intrusions granitiques de la région de Bodsjö ont été réparties en types I et S. La classification des granites de Suède selon Wilson, est utilisée dans le cadre de la présente étude et permet de relier les différentes intrusions granitiques de la région à un modèle de tectonique des plaques. Ce modèle est caractérisé par deux périodes de subduction : la première a donné naissance aux granites primorogéniques, la seconde au Rätan granite. Les granites tardi-orogéniques et le Revsund granite représentent, pour leur part, la transition entre une orogenès Andinotype et une orogenèse Hercynotype à la fin de la première période de subduction.

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.
