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
Conserving and restoring biodiversity and ecosystem services in African tropical rainforest
No full textAfrican tropical rainforests, hotspots of species biodiversity and endemism, are often reduced to forest islands within a sea of some of the world’s poorest, fastest growing, and most resource-dependent human populations. Logging and clearing land for agriculture destroy or degrade extensive areas of tropical rainforest, threatening flora, fauna, and the ecosystem services on which people depend. Natural resource managers are challenged to maintain multi-functional landscapes while balancing conflicting demands for resources, biodiversity conservation, and ecosystem services. Working in Kibale National Park, Uganda, I studied the legacies of land-use histories and restoration on spatial and temporal variation in rainforest tree communities, as well as on animal habitat suitability and the provision of ecosystem services. I compared unlogged forests with forests regenerating after logging, plantations of exotic timber, fire, and subsistence farming. I investigate the potential to restore native forest on abandoned farmland via remnant, exotic “legacy” trees that attract frugivorous seed-dispersers. Fruit legacy trees recruited large-seeded, late-successional forest tree species. I caution against removing legacy trees without weighing the risk of invasion against the benefit of restoring native forest. I also investigated spatial and temporal change in logged and unlogged forest over a 24 year period, finding that variation in tree assemblages was greater within than across years. Spatial heterogeneity in unlogged forest can be partially attributed to past disturbance factors, and in harvested forests had more to do with pre-logging conditions than logging intensity. Finally, I compared synergies and trade-offs among tree diversity, animal habitat suitability, and ecosystem services in areas with different land-use histories. I found consistent, positive relationships among tree diversity, primate and elephant foods, and provisioning, regulating, and cultural services. My results demonstrate that managing forest landscapes to maximize tree diversity can also maximize stocks of animal foods and ecosystem services. My results can be used to inform current policies in Kibale with respect to managing exotic species, tree planting, preventing fire, and resource access agreements with local communities.Les forêts tropicales africaines sont un lieu de biodiversité et d'endémisme extrêmement élevés. Cependant, elles sont souvent fragmentées et réduites à de petits îlots au sein d’une mer humaine considérée comme étant une population des plus pauvres du monde, au taux de croissance le plus rapide, et aux dépendances les plus élevées aux les ressources naturelles. La coupe forestière et le défrichement des terres pour l'agriculture détruisent ou dégradent les vastes étendues de forêt tropicale, menaçant ainsi la flore, la faune et les services liés aux écosystèmes dont dépendent les gens. Les gestionnaires des ressources naturelles sont donc mis au défi de maintenir des zones à usage multiple qui doivent non seulement accommoder l’exploitation des ressources naturelles, mais aussi la conservation de la biodiversité et le maintien des services liés aux écosystèmes. Dans le Parc National de Kibale en Ouganda, j'ai étudié l’effet de l'aménagement et de la restauration sur la diversité des communautés d'arbres tropicaux, sur la qualité de l'habitat pour les animaux, et sur le maintien des services liés aux écosystèmes. J'ai comparé des forêts non-exploitées avec des forêts post-exploitation, des plantations de bois exotique, des forêts affectées par le feu et des aires d’agriculture de subsistance. J'ai étudié le potentiel de restauration de terres agricoles abandonnées en utilisant des arbres exotiques qui attirent les animaux frugivores qui dispersent des semences d’arbres. Mes résultats démontrent que ces anciens arbres fruitiers attirent des animaux porteurs d’essences forestières à grosse graine, qui arrivent tard dans le processus de succession. Je mets en garde contre la coupe des tels arbres sans évaluer les conséquences que pourraient entraîner leur disparition: l’invasion d’autres espèces d’arbres plutôt que la restauration d’une forêt naturelle. J'ai aussi étudié, sur une période de 24 ans, les changements au sein de forêts exploitées et non-exploitées sur une échelle temporelle et spatiale, démontrant que la variation au niveau de l’assemblage des arbres était supérieure au sein d’une même année plutôt qu’entre les années. L'hétérogénéité spatiale dans une forêt non-exploitée peut être partiellement attribuée à une perturbation antérieure et, dans les forêts exploitées, à l’état de la forêt avant exploitation plutôt qu’à l'intensité des activités d'exploitation forestière. Finalement, j'ai comparé les synergies et les compromis entre différentes espèces d’arbres, la qualité des habitats pour les animaux et les services liés aux écosystèmes dans des zones ayant des historiques d'utilisation des sols différents. J'ai trouvé des relations positives et constantes entre la diversité des arbres, les aliments utilisés par les primates et les éléphants et l’approvisionnement, la régulation et les services culturels. Mes résultats démontrent que la gestion des forêts afin de maximiser la diversité des arbres peut également maximiser les stocks d'aliments pour les animaux sauvages ainsi que les services liés aux écosystèmes. Mes résultats peuvent aussi servir à informer les politiques actuelles du parc de Kibale en ce qui concerne la gestion des espèces exotiques, la reforestation, la prévention des feux de forêt, ainsi que les ententes avec les communautés locales afin qu’elles aient accès aux ressources naturelles

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.
