    The 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” 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

    We 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

    We 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

    We 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

    Streets trees in the city of Viçosa, MG: phytosociological and socioeconomic parameters

    O intenso processo de urbanização tem gerado diversos impactos negativos nas cidades, acarretando em prejuízos para a população que reside nesses locais. Uma das formas de alcançar a mitigação de alguns desses impactos é através da presença de vegetação nas áreas urbanas, que promovem uma série de benefícios. Toda a vegetação presente na cidade, compreendendo as praças, fragmentos remanescentes de mata nativa, bosques, jardins, arborização de ruas, dentre outros, formam a floresta urbana. Dessa forma, é necessário que haja planejamento e adequação dos ambientes urbanos para potencialização dos benefícios advindos da presença de vegetação. Com isso, o objetivo desse estudo foi realizar um diagnóstico quali-quantitativo da arborização de ruas da cidade de Viçosa-MG, para subsidiar o planejamento e gestão da floresta urbana. Para isto, foi realizado um inventario florestal urbano do tipo censo, entre outubro/2020 e julho/2021, onde parâmetros quali-quantitativos foram obtidos em campo para caracterizar a estrutura física das ruas e dos indivíduos que compõe a arborização. Com os dados obtidos, foi determinada a composição e distribuição florística, a caracterização dendrométrica das espécies, a qualidade da arborização e a relação com o meio físico da cidade como um todo e das suas regiões e a relação entre a distribuição da arborização viária com os fatores socioeconômicos de cada região. Foram mensurados 2381 indivíduos nas ruas da cidade, distribuídos em 78 espécies, predominantemente nativas do Brasil. A maioria dos indivíduos foram espécies de pequeno a médio porte (cerca de 87%), com boas condições de copa (78%), tronco (86%) e raiz (60%), sem problemas fitossanitários (92%) e que não necessitavam de práticas de manejo (81%). Em média, 19% das árvores ofereceram obstáculo à passagem de pedestres e 38% não possuem área livre de canteiro disponível. A análise fitossociológica indicou que as espécies com maior valor de importância para a arborização viária da cidade foram Pleroma granulosum, seguida por Moquilea tomentosa e Cenostigma pluviosum. De acordo com o cálculo dos índices espaciais, Viçosa tem baixo grau de arborização, com média de 21,5 árvores por quilômetro de calçada, sendo necessário plantar mais de 17 mil árvores para atingir o número ideal. Porém, por meio da caracterização do meio físico, foi constatado que isso não é simples, devido a cidade apresentar ruas e calçadas estreitas, com média de 9,8m e 1,5m, respectivamente. Foi observado que regiões menos populosas e com maior renda tendem a apresentar mais árvores na cidade de Viçosa. Por fim, foi possível concluir que a arborização viária da cidade de Viçosa tem boa qualidade, mas necessita de incremento quantitativo e melhor distribuição espacial. Porém, para que isso ocorra, é necessário a adequação da infraestrutura urbana, de modo a priorizar a existência de árvores nas ruas, impulsionando o fornecimento de benefícios diretos à população de toda a cidade.

Censo florestal.The intense urbanization process has generated several negative impacts on cities, causing damage to the population that resides in these places. One of the ways to achieve the mitigation of some of these impacts is through the presence of vegetation in urban areas, which promotes a series of benefits. All the vegetation present in the city, including squares, remaining fragments of native forest, woods, gardens, street trees, among others, form the urban forest. Thus, it is necessary to have planning and adaptation of urban environments to maximize the benefits arising from the presence of vegetation. With that, the objective of this study was to carry out a qualitative-quantitative diagnosis of the afforestation of streets in the city of Viçosa- MG, to subsidize the planning and management of the urban forest. For this, an urban forest inventory of the census type was carried out, between October/2020 and July/2021, where quali-quantitative parameters were obtained in the field to characterize the physical structure of the streets and the individuals that make up the afforestation. With the data obtained, the floristic composition and distribution, the dendrometric characterization of the species, the quality of the afforestation and the relationship with the physical environment of the city as a whole and its regions and the relationship between the distribution of street afforestation with the socioeconomic factors in each region. A total of 2381 individuals were measured in the streets of the city, distributed in 78 species, predominantly native to Brazil. Most individuals were small to medium-sized species (about 87%), with good canopy conditions (78%), trunk (86%) and root (60%), without phytosanitary problems (92%) and not needed management practices (81%). On average, 19% of the trees provided an obstacle to pedestrians' passage and 38% did not have a free area of flowerbeds available. The phytosociological analysis indicated that the species with the highest value of importance for the urban afforestation were Pleroma granulosum, followed by Moquilea tomentosa and Cenostigma pluviosum. According to the calculation of spatial indexes, Viçosa has a low degree of afforestation, with an average of 21.5 trees per kilometer of sidewalk, and it is necessary to plant more than 17 thousand trees to reach the ideal number. However, through the characterization of the physical environment, it was found that this is not simple, because the city has narrow streets and sidewalks, with an average of 9.8 m and 1.5 m, respectively. It was observed that less populated regions with higher income tend to have more trees in the city of Viçosa. Finally, it was possible to conclude that the street afforestation in the city of Viçosa has good quality, but needs quantitative increment and better spatial distribution. However, for this to occur, it is necessary to adapt the urban infrastructure, in order to prioritize the existence of trees on the streets, boosting the provision of direct benefits to the population of the entire city.

    Author Under Sail The Imagination of Jack London, 1893-1902

    No full text
    In 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.
