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
Efeitos de um programa de treinamento físico multicomponente em parâmetros da composição corporal, ângulo de fase e qualidade muscular em sobreviventes da Covid-19: um recorte do COvid-19 and REhabilitation Study (CORE-Study)
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Desportos, Programa de Pós-Graduação em Educação Física, Florianópolis, 2024.Alterações de composição corporal, como a obesidade e a sarcopenia, ou baixos valores de ângulo de fase, estão associadas com um mal prognóstico da COVID-19, bem como podem ser consequências da doença, já que pode desencadear um quadro inflamatório persistente após a fase aguda da infecção, propiciando uma resistência anabólica e um possível acúmulo de gordura subcutânea e visceral. Umas das formas mais eficazes para reabilitação e melhora dos parâmetros da composição corporal é a prática de exercício físico, especialmente o aeróbio e o de força. Porém, poucos ensaios clínicos foram realizados nesse cenário, e as informações até o momento advém de estudos com menor rigor metodológico, como estudos observacionais ou sem grupo controle. Portanto, este trabalho teve como objetivo analisar o efeito de 24 semanas de um programa de treinamento físico multicomponente sobre a composição corporal, ângulo de fase e qualidade muscular em sobreviventes da COVID-19. O estudo caracteriza-se como ensaio clínico randomizado, controlado, de superioridade, unicêntrico, conduzido em paralelo, com cegamento de avaliadores dos desfechos e aninhado a um projeto maior chamado Covid-19 and Rehabilitation Study (CORE- Study), que foi realizado na Universidade Federal de Santa Catarina. Os participantes, selecionados de modo não probabilístico, e que desenvolveram quadros severos à críticos na fase aguda da doença, foram divididos em dois grupos: treinamento multicomponte (GI) e grupo controle (GC), que recebeu orientações sobre a prática de atividade física. A intervenção foi composta por duas fases, objetivando primeiramente progressão de volume (fase 1), e posteriormente de intensidade (fase 2). A composição corporal foi avaliada através da densitometria computadorizada por absorciometria radiológica de dupla energia e o ângulo de fase calculado a partir dos valores brutos de resistência e reatância obtidos por bioimpedância. A qualidade muscular foi avaliada através da razão entre a força isométrica máxima de membros superiores e inferiores e suas respectivas massas magras. A análise dos dados foi realizada por intenção de tratar (ITT) e por protocolo (PP), através da utilização de equações de estimativa generalizada, adotando-se o post-hoc de Bonferroni. Adicionalmente, o tamanho de efeito (TE) entre grupos foi calculado. Quarenta participantes (18 mulheres, 52,25 ± 13,00 anos) foram randomizados em GI (n=21) e GC (n=19). A análise ITT não evidenciou nenhuma alteração nos parâmetros analisados. A análise PP identificou que o GC apresentou aumento no IMC (0,58 kg/m2; p = 0,018; TE: -0,15), na massa gorda (1,46 kg; p = 0,004; TE: -0,22) e na quantidade de gordura visceral (68,81 g; p = 0,036; TE: -0,32). Para a variável percentual de gordura, o GI apresentou redução (-0,53%; p = 0,030; TE: -0,16). Portanto, podemos concluir que o programa de treinamento multicompontente, aqui proposto, não foi superior às orientações de atividade física, com o objetivo de gerar modificações de parâmetros de composição corporal, ângulo de fase e qualidade muscular em sobreviventes da COVID-19. Porém, parece que nos participantes que cumpriram um mínimo de 70% das sessões propostas, existe um pequeno efeito no que tange aspectos de proteção em relação ao aumento da gordura corporal, especialmente a gordura visceral.Abstract: Changes in body composition, such as obesity and sarcopenia, or low phase angle values, are associated with a poor prognosis of COVID-19, and may be consequences of the disease, as it can trigger a persistent inflammatory condition after the phase acute infection, providing anabolic resistance and a possible accumulation of subcutaneous and visceral fat. One of the most effective ways to rehabilitate and improve body composition parameters is physical exercise, especially aerobic and strength training. However, few clinical trials have been carried out in this scenario, and the information to date comes from studies with less methodological rigor, such as observational studies or studies without a control group. Therefore, this work aims to analyze the effect of 24 weeks of a multicomponent physical training program on body composition, phase angle and muscle quality in COVID-19 survivors. The study is characterized as a randomized, controlled, superiority, single-center clinical trial, conducted in parallel, with blinding of outcome assessors and nested within a larger project called Covid-19 and Rehabilitation Study (CORE-Study), which was carried out at Federal University of Santa Catarina. The participants, selected in a non- probabilistic way, and who developed severe to critical conditions in the acute phase of the disease, were divided into two groups: multicomponent training (IG) and control group (CG), which received guidance on the practice of physical activity. The intervention consisted of two phases, aiming first at volume progression (phase 1), and subsequently at intensity (phase 2). Body composition was assessed using whole- body dual-energy X-ray absorptiometry scan and the phase angle was calculated from the raw values of resistance and reactance obtained by bioimpedance. Muscle quality was assessed through the ratio between the maximum isometric strength of the upper and lower limbs and their respective lean mass. Data analysis was carried out by intention to treat (ITT) and by per protocol (PP), by generalized estimating equations, adopting the Bonferroni post-hoc. Additionally, the effect size (ES) between groups was calculated. Forty participants (18 women, 52.25 ± 13.00 years) were randomized into IG (n=21) and CG (n=19). The ITT analysis did not show any changes in the analyzed parameters. The PP analysis identified that the CG showed an increase in BMI (0.58 kg/m2; p = 0.018; ES: -0.15), in fat mass (1.46 kg; p = 0.004; ES: -0.22) and the amount of visceral fat (68.81 g; p = 0.036; ES: -0.32). For the fat percentage variable, the IG showed a reduction (-0.53%; p = 0.030; ES: -0.16). Therefore, we can conclude that the multicomponent training program proposed here was not superior to physical activity guidelines, with the aim of generating changes in body composition parameters, phase angle and muscle quality in COVID-19 survivors. However, it appears that in participants who completed a minimum of 70% of the proposed sessions, there is a small effect in terms of protective aspects in relation to the increase in body fat, especially visceral fat
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

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.
