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
Impacto da têmpera pós-soldagem na microestrutura e nas propriedades mecânicas de aços de alta resistência e baixa liga
Full text linkShielded Metal Arc Welding (SMAW) is the most widely used welding technique in engineering industries. Compared to other arc welding techniques like TIG, SMAW is less heat-concentrating. However, welding thick jobs using SMAW can result in serious issues such as structural distortion due to non-uniform input heat distribution. High thermal stresses and distortions can degrade mechanical properties, similar to high input heat. Fast heat removal may prevent such defects, and different quenching media like sand, water, and oil were used to investigate variations in mechanical properties. High-strength low-alloy steel was selected due to its good weldability and easy availability, which makes it suitable for many industrial applications, such as in the space and defense industries. The tensile testing results showed that oil quenching was superior to other quenching techniques because oil-cooled joints had the highest tensile strength and ductility. However, water-cooled joints showed the highest yield strength, but oil-quenched joints had the highest welding efficiency. The hardness of water-cooled joints in the heat-affected zone and weld zone was greater due to rapid cooling in water. The impact energy of oil-cooled joints in the heat-affected zone was superior to that of other joints. Overall, the mechanical properties of oil-cooled joints were superior and showed better geometric configuration, such as minimal distortions.La soldadura por arco metálico protegido (SMAW) es la técnica de soldadura más utilizada en las industrias de ingeniería. En comparación con otras técnicas de soldadura por arco como TIG, SMAW concentra menos calor. Sin embargo, soldar trabajos gruesos utilizando SMAW puede provocar problemas graves, como distorsión estructural debido a una distribución no uniforme del calor de entrada. Las altas tensiones y distorsiones térmicas pueden degradar las propiedades mecánicas, de forma similar al calor de entrada elevado. La eliminación rápida del calor puede prevenir tales defectos, y se utilizaron diferentes medios de enfriamiento como arena, agua y aceite para investigar las variaciones en las propiedades mecánicas. Se seleccionó acero de alta resistencia y baja aleación debido a su buena soldabilidad y fácil disponibilidad, lo que lo hace adecuado para muchas aplicaciones industriales, como en las industrias espacial y de defensa. Los resultados de las pruebas de tracción mostraron que el enfriamiento con aceite fue superior a otras técnicas de enfriamiento porque las juntas enfriadas por aceite tenían la mayor resistencia a la tracción y ductilidad. Sin embargo, las uniones enfriadas por agua mostraron el límite elástico más alto, pero las uniones enfriadas con aceite tuvieron la mayor eficiencia de soldadura. La dureza de las uniones enfriadas por agua en la zona afectada por el calor y en la zona de soldadura fue mayor debido al rápido enfriamiento en agua. La energía de impacto de las juntas enfriadas por aceite en la zona afectada por el calor fue superior a la de otras juntas. En general, las propiedades mecánicas de las juntas enfriadas por aceite fueron superiores y mostraron una mejor configuración geométrica, como distorsiones mínimas.A soldagem por arco metálico blindado (SMAW) é a técnica de soldagem mais amplamente utilizada nas indústrias de engenharia.

O aço de alta resistência e baixa liga foi selecionado devido à sua boa soldabilidade e fácil disponibilidade, o que o torna adequado para muitas aplicações industriais, como nas indústrias espacial e de defesa. Os resultados dos testes de tração mostraram que a têmpera em óleo foi superior a outras técnicas de têmpera porque as juntas resfriadas a óleo apresentaram maior resistência à tração e ductilidade. No entanto, as juntas resfriadas a água apresentaram o maior limite de escoamento, mas as juntas temperadas a óleo tiveram a maior eficiência de soldagem. A dureza das juntas resfriadas a água na zona afetada pelo calor e na zona de solda foi maior devido ao rápido resfriamento em água. A energia de impacto das juntas resfriadas a óleo na zona afetada pelo calor foi superior à das outras juntas. No geral, as propriedades mecânicas das juntas resfriadas a óleo foram superiores e apresentaram melhor configuração geométrica, como distorções mínimas
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.
