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
El fenómeno de segundas víctimas en enfermeras de Unidades de Cuidado Intensivo Adulto en Hospitales Públicos de Chile: un abordaje mixto
Get PDFPrograma de Doctorat en Infermeria i Salut[spa] INTRODUCCIÓN: Los eventos adversos en hospitales son un problema de relevancia global debido a la morbilidad y mortalidad, así como a los costos que generan para la salud pública. En un evento adverso, la primera víctima es el paciente y su familia, la segunda víctima es el profesional de la salud y la tercera víctima es la institución. El fenómeno de la segunda víctima puede tener graves repercusiones emocionales y físicas para el profesional e influir negativamente en la cultura de calidad y seguridad de la institución.
OBJETIVOS: Determinar el nivel de experiencia y apoyo para las segundas víctimas en enfermeras que trabajan en unidades de cuidados intensivos en hospitales públicos en Chile, y describir la trayectoria natural de recuperación de afrontamiento de las segundas víctimas en enfermeras que laboran en estas unidades.[eng] INTRODUCTION: Adverse events in hospitals are a globally significant problem due to the morbidity and mortality they cause, as well as the costs they generate for public health. In an adverse event, the first victim is the patient and their family, the second victim is the healthcare professional, and the third victim is the institution. The phenomenon of the second victim can have serious emotional and physical repercussions for the professional and can negatively influence the institution's culture of quality and safety.
AIM: To determine the level of experience and support for second victims among nurses working in intensive care units in public hospitals in Chile and to describe the natural recovery trajectory of second victims among nurses working in these units

Persistencia microbiana de importancia intrahospitalaria en uniformes clínicos a raíz de la pandemia de COVID-19
No full textIntroduction: Hand washing is the measure that has the greatest impact on the prevention of infections associated with health care. There is little evidence of the role of clinical uniforms as a vector in cross-transmission of infections in hospitals.
Method: A rapid review was carried out with Cochrane criteria and PRISMA check list with access to Pubmed, Ovid, ProQuest and Google Academic databases in Spanish and English from 2010-2020. The objective of the review was to search for evidence of the persistence of microorganisms of intra-hospital importance in clinical uniforms, in light of the current Covid-19 pandemic. The critical analysis of the articles was carried out with tools from the Joanna Briggs Institute (checklist analytical studies, case series, text and opinion, controlled clinical trials and systematic reviews)
Results: The initial search yielded 1703 articles, of which 8 articles were selected. Evidence of persistence of microorganisms is found in clinical uniforms. The most contaminated areas are pockets and sleeves. MERS-COV and SARS-COV, have shown persistence in aluminum up to 48 hours, wood 4 days, paper 24 hours. In genus, SARS-COV 2 has shown a persistence of 2 days.
Conclusions: There is evidence of persistence of bacterial and viral microorganisms in clinical uniforms. The most contaminated places are pockets and sleeves. After the position, hours later there is evidence of the presence of microorganisms in clinical uniforms.Introdução: A lavagem das mãos é a medida de maior impacto na prevenção de infecções associadas aos cuidados de saúde. Existem poucas evidências sobre o papel que desempenham os uniformes clínicos como vetor na transmissão cruzada de infecções em hospitais.
Método: Foi realizada uma revisão rápida com os critérios Cochrane e checklist PRISMA com acesso às bases de dados PubMed, Ovid, ProQuest e Google Académico em espanhol e inglês de 2010-2020. O objetivo estabelecido foi buscar evidência sobre a persistência de microrganismos de importância intra-hospitalar em uniformes clínicos, como resultado da atual pandemia de COVID-19. A análise crítica dos artigos foi realizada com ferramenta do Joanna Briggs Institute (checklist de estudos analíticos, série de casos, texto e opinião, ensaios clínicos controlados e revisões sistemáticas).
Resultados: A busca inicial resultou em 1703 artigos, dos quais foram selecionados 8. Foram encontradas evidências de persistência de microrganismos em uniformes clínicos. As áreas mais contaminadas são os bolsos e as mangas. MERS-COV e SARS-COV mostraram persistência em alumínio até 48 horas, madeira 4 dias, papel até 24 horas. No gênero, o SARS-COV-2 mostrou uma persistência de 2 dias.
Conclusões: Existe evidência da persistência de microrganismos bacterianos e virais em uniformes clínicos. Os locais mais contaminados são os bolsos e as mangas. Uma vez colocado, é demonstrada a presença de microrganismos em uniformes clínicos horas depois. Devem ser implementadas medidas que tomem em conta o papel potencial de transmissão de patógenos de uniformes clínicos em hospitais.Introducción: El lavado de manos es la medida que más impacta en la prevención de infecciones asociadas a la atención en salud.

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
