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
Stroke mortality in Minas Gerais: spatial-temporal patterns and association with social
No full textAs doenças cardiovasculares são a principal causa de morte no Brasil e no mundo e representa um problema de saúde pública. Dentre elas, o acidente vascular cerebral (AVC) corresponde à terceira principal causa de morte no Brasil. Parte dessas mortes poderia ser evitada abordando-se os fatores de risco. O presente estudo tem como objetivo analisar o padrão espaço-temporal da mortalidade por AVC em Minas Gerais, de 1980 a 2021, e sua respectiva associação com indicadores sociais. O presente estudo tem duas hipóteses. A primeira supõe a existência de conglomerados de taxas altas de mortalidade por AVC na região norte e nordeste de Minas Gerais, área com piores condições socioeconômicas; e conglomerados de taxas baixas na região sul e sudoeste do estado. A segunda hipótese supõe a identificação de associação negativa da mortalidade por AVC com indicadores que representam o nível socioeconômico da população. A identificação de conglomerados e indicadores associados podem auxiliar os gestores na formulação de políticas públicas intersetoriais. Trata-se de um estudo de base populacional, com dados secundários agrupados por municípios e microrregiões. As estatísticas vitais foram coletadas no DATASUS, os indicadores sociais foram as cinco dimensões do Índice Mineiro de Responsabilidade Social: saúde, educação, segurança, vulnerabilidade e saneamento. Na análise de tendência temporal foi utilizada regressão linear segmentada. Foram consideradas as taxas bruta, ajustada por idade e sexo, específicas por faixas etárias. A análise espaço-temporal foi conduzida em duas escalas de agregação espacial, sendo a primeira com as 66 microrregiões de Minas Gerais. Foram usados mapas coropléticos com taxas quinquenais e teste de varredura espacial, de 1980 a 2021. Na segunda análise foram considerados os 853 municípios de Minas Gerais, de 2014 a 2022. Foi utilizado o teste de varredura espacial e a associação da mortalidade por AVC com os indicadores sociais foi estimada pela regressão espacial (spatial lag). De 1980 a 2021 ocorreram 392.521 mortes por AVC (taxa de 52,6/100 mil habitantes-ano). Todas as taxas (bruta, ajustada, por faixas etárias) apresentaram tendência de diminuição significativa, com velocidade menor na taxa bruta (variação percentual anual [VPA] = -0,70) e maior na faixa etária de 20 a 39 anos (VPA = -4,48). Na análise por microrregiões, identificou-se um conglomerado no sul/sudeste de taxas altas (1980-1999; risco relativo [RR] = 2,06), e no norte/noroeste, com taxas baixas (2008-2021; RR = 0,59). A diminuição foi mais intensa no sul/sudeste (VPA = -3,64). A análise municipal, puramente espacial, identificou 13 conglomerados dispersos, sendo oito de taxas altas (risco relativo [RR] = 1,08 a 1,31) cinco de taxas baixas (RR = 0,80 a 0,89). A análise espaço-temporal identificou quatro conglomerados de taxas altas (2014-2017; RR = 1,18 a 1,48) e três de taxas baixas (2018-2022; RR = 0,66 a 0,87) dispersos no estado. Dado que foram identificados conglomerados de taxas altas e baixas dispersos pelo estado, a primeira hipótese foi refutada. Foi identificada associação negativa da mortalidade por AVC com os indicadores saúde (? = 7,64), educação (? = -7,21), segurança (? = -3,43) e R2 de 0,41, portanto a segunda hipótese foi confirmada. Este estudo pode subsidiar a formulação de políticas públicas intersetoriais, visando a redução das desigualdades sociaisCardiovascular diseases are the leading cause of death in Brazil and worldwide and represent a public health problem. Among them, stroke is the third leading cause of death in Brazil. Some of these deaths could be prevented by addressing risk factors. This study aims to analyze the spatial-temporal pattern of stroke mortality in Minas Gerais, from 1980 to 2021, and its respective association with social indicators. This study has two hypotheses. The first assumes the existence of clusters of high stroke mortality rates in the north and northeast regions of Minas Gerais, areas with the worst socioeconomic conditions; and clusters of low rates in the south and southwest regions of the state. The second hypothesis assumes the identification of a negative association between stroke mortality and indicators that represent the socioeconomic level of the population. The identification of clusters and associated indicators can assist managers in formulating intersectoral public policies. This is a population-based study with secondary data grouped by municipalities and microregions. Vital statistics were collected from DATASUS, and social indicators were the five dimensions of the Minas Gerais Social Responsibility Index: health, education, safety, vulnerability, and sanitation. Segmented linear regression was used in the temporal trend analysis. Crude rates, adjusted for age and sex, and specific to age groups were considered. The spatiotemporal analysis was conducted on two spatial aggregation scales, the first with the 66 microregions of Minas Gerais. Choropleth maps with five-year rates and a spatial scanning test were used, from 1980 to 2021. The second analysis considered the 853 municipalities of Minas Gerais, from 2014 to 2022. The spatial scanning test was used and the association of stroke mortality with social indicators was estimated by spatial regression (spatial lag). From 1980 to 2021, 392,521 deaths from stroke occurred (rate of 52.6/100,000 population-years). All rates (crude, adjusted, by age group) showed a significant downward trend, with a slower speed in the crude rate (annual percentage change [APC] = -0.70) and a faster rate in the 20 to 39 age group (APC = -4.48). In the analysis by microregions, a cluster was identified in the south/southeast with high rates (1980-1999; relative risk [RR] = 2.06), and in the north/northwest, with low rates (2008-2021; RR = 0.59). The decrease was more intense in the south/southeast (APC = 3.64). The municipal analysis, purely spatial, identified 13 dispersed clusters, eight with high rates (relative risk [RR] = 1.08 to 1.31) and five with low rates (RR = 0.80 to 0.89). The spatiotemporal analysis identified four clusters with high rates (2014-2017; RR = 1.18 to 1.48) and three with low rates (2018-2022; RR = 0.66 to 0.87) dispersed throughout the state. Given that clusters with high and low rates were identified throughout the state, the first hypothesis was refuted. A negative association between stroke mortality and the indicators health (? = 7.64), education (? = -7.21), and safety (? = -3.43) was identified, with an R2 of 0.41, therefore the second hypothesis was confirmed. This study can support the formulation of intersectoral public policies, aiming at reducing social inequalitie
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.
