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
Dispnéia, nível de atividade física e fatores emocionais e sociais em gestantes em contexto de pandemia por COVID-19 em Portugal
Get PDFIntroduction: Pregnancy is a period in which several multimodal changes occur in women. This study aims to characterize dyspnea, the level of physical activity and emotional and social aspects in pregnant women in the context of COVID-19 in Portugal.
Methods: An observational and cross-sectional study was carried out in 2020, in Portugal. Given the context of restrictions on personal contact in force in the country at the time, a self-completion questionnaire was prepared for online dissemination on Portuguese social networks aimed at pregnant women. The questionnaire included questions for sample characterization, as well as the m Medical Research Council (MRC) to assess dyspnea. The Portuguese version of the International Physical Activity Questionnaire for Pregnant Women (PPAQ) was also integrated to characterize the level of physical activity, the Anxiety, Depression and Stress Scale (DASS-21) to assess emotional factors and the Social Support Satisfaction Scale (ESSS) to assess the person's satisfaction with social support.
Results: Ten pregnant women participated in this study. Only one reported grade 1 dyspnea – “no problems with shortness of breath, except in case of intense exercise”, in the 3rd trimester (T), age between 34-37 years, adequate weight, greater energy expenditure in moderate activities, and presenting strong evidence of emotional changes and satisfaction with social support below average. Four pregnant women reported grade 2 dyspnea – “shortness of breath when rushing or climbing slopes”, being in the 2nd or 3rd T, aged between 30-33 years, presenting low weight, adequate weight or overweight, referring to greater energy expenditure in sedentary or light activities. Their satisfaction with social support was median and only one pregnant woman reported emotional changes (moderate anxiety and depression). Five pregnant women reported grade 3 dyspnea – “walking slower than other people due to shortness of breath or needing to stop for breath when walking at their normal pace”. Of these, 4 were in the 3rd T, aged between 26-37 years, with adequate or excess weight, with greater energy expenditure in light or moderate activities. Satisfaction with social support was average and one pregnant woman showed emotional changes (severe anxiety and moderate depression and stress). One of the pregnant women with grade 3 dyspnea was in the 1st T and reported similar energy expenditure in activities at all levels, showing no emotional changes and reporting low satisfaction with social support.
Conclusion: In the small sample of this study, there is a high prevalence of dyspnea in pregnant women (9 out of 10), with greater energy expenditure in sedentary or light activities (7 out of 10). In general, satisfaction with social support seems to be medium or low, with indicators of anxiety, depression and stress in some pregnant women (1-2 out of 10). Given the low sample size, it was not possible to establish a correlation between the variables, and it is important to carry out future studies in this sense.Introdução: A gestação é um período em que ocorrem várias alterações multimodais na mulher. Este estudo pretende caracterizar a dispneia, o nível de atividade física e aspetos emocionais e sociais em gestantes em contexto de COVID-19 em Portugal. Métodos: Realizou-se um estudo observacional e transversal em 2020, em Portugal. Mediante o contexto de restrições de contacto pessoal vigente no país à data, foi elaborado um questionário de autopreenchimento para divulgação online, em redes sociais portuguesas destinadas a gestantes. O questionário incluiu questões para caracterização da amostra, assim como a Medical Research Council (MRC) para avaliar a dispneia. Foi também integrada a versão portuguesa do Questionário Internacional de Atividade Física para Gestantes (PPAQ) para caracterizar o nível de atividade física, a Escala de Ansiedade, Depressão e Stress (DASS-21) para avaliar fatores emocionais e Escala de Satisfação com Suporte Social (ESSS) para avaliar o satisfação da pessoa com o suporte social. Resultados: Participaram neste estudo 10 gestantes. Apenas uma reportou dispneia grau 1 – “sem problemas de falta de ar, exceto em caso de exercício intenso”, no 3º trimestre (T), idade entre o 34-37 anos, peso adequado, maior dispêndio energético em atividades moderadas, e apresentando fortes indícios de alterações emocionais e satisfação com suporte social abaixo da média. Quatro gestantes referiram dispneia grau 2 – “falta de ar quando se apressa ou sobe inclinações”, estando no 2º ou 3ºT, tendo idades compreendidas entre 30-33 anos, apresentando baixo peso, peso adequado ou excesso de peso, referindo maior dispêndio energético em atividades sedentárias ou leves. A sua satisfação com o suporte social foi mediana e apenas uma gestante reportou alterações emocionais (ansiedade e depressão moderadas). Cinco gestantes referiram dispneia grau 3 – “andar mais devagar do que outras pessoas devido à falta de ar, ou precisar parar para respirar ao caminhar ao seu ritmo normal”. Destas, 4 estavam no 3ºT, tinham idades compreendidas entre 26-37 anos, com peso adequado ou em excesso, com maior dispêndio energético em atividades leves ou moderadas. A satisfação com o suporte social foi mediano e uma gestante evidenciou alterações emocionais (ansiedade severa e depressão e stress moderados). Uma das gestantes com dispneia grau 3 estava no 1ºT e reportou dispêndio energético semelhante em atividades de todos os níveis, não evidenciando alterações emocionais e referindo ter uma baixa satisfação com suporte social. Conclusão: Na pequena amostra deste estudo, conclui-se uma prevalência elevada de dispneia em gestantes (9 em 10), com maior dispêndio energético em atividades sedentárias ou leves (7 em 10). Na generalidade, a satisfação com o suporte social parece ser mediano ou baixo, existindo indicadores de ansiedade, depressão e stress em algumas gestantes (1-2 em 10). Perante o baixo nº amostral, não foi possível estabelecer uma correlação entre as variáveis, sendo importante realizar estudos futuros nesse sentido.Mestrado em Fisioterapi
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

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.
