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
Avaliação do desenvolvimento e seguimento do bebé pré-termo
Full text linkRevista de Psicologia da Criança e do Adolescente. - ISSN 1647-4120. - V. 10, n. 2 (2019). - p. 51-65.The diagnostic and therapeutic advances in the Neonatology area have resulted in a significant decrease in the mortality rate of preterm newborns and, consequently, an increase in the morbidity of these babies. The concern with the evaluation of its evolution has become increasingly evident, requiring strategies to reduce the repercussion of possible compromises and to increase the quality of life of these children. This study aims to investigate about the main instrument for assessing the development and follow-up of preterm babies. A systematic search was conducted in the main databases, consulting articles and books that provide detail on studies, evaluations and instruments. It was found that developmental assessment and follow-up are performed through screening and developmental diagnosis tests that examine the most relevant aspects in the various age groups. Twenty-one evaluation instruments for preterm development and follow-up were identified, which can be divided into three categories: the comprehensive, the specifics and the neurological and neurobehavioral exams. Studies show that the Bayley Scales of Infant Development - Bayley III (BSID III) are the most widely used scales for assessing the preterm. It is a comprehensive assessment tool that points out the strengths and weaknesses as well as the baby’s competencies. The scales are most indicated for early identification of risk for development, elaboration of intervention projects and to provide guidance and information to parents about the evolution of the child, whose follow-up should be continuous and systematic, carried out by an interdisciplinary team.Os avanços diagnósticos e terapêuticos na área da Neonatologia resultaram numa diminuição expressiva da taxa de mortalidade de recém-nascidos pré-termo e, consequentemente, num aumento da morbilidade desses bebés. A preocupação com a avaliação do desenvolvimento foi-se tornando cada vez mais evidente, necessitando de estratégias para reduzir a repercussão de possíveis compromissos e potencializar a qualidade de vida dessas crianças. Este trabalho tem o objetivo de investigar o principal instrumento para a avaliação do desenvolvimento e o seguimento do bebé pré-termo. Foi realizada uma pesquisa sistemática nas principais bases de dados, consulta aos artigos e aos livros que fornecem detalhes sobre estudos, avaliações e instrumentos. Verificou-se que a avaliação do desenvolvimento e o seguimento de bebés pré-termo são realizados por meio de testes de triagem e diagnóstico que examinam os aspectos mais relevantes nas diversas faixas etárias. Foram identificados 21 instrumentos que podem ser divididos em três categorias: os completos, os específicos e os exames neurológicos e de neuro comportamento. Os estudos revelam que as Bayley Scales of Infant Development - Bayley III (BSID III) são as escalas mais utilizadas para avaliar o bebé pré-termo. É um instrumento de avaliação com alcance abrangente que aponta os pontos fortes e fracos bem como as competências do bebé. São as escalas mais indicadas para a identificação precoce de risco para o desenvolvimento, elaboração de projetos interventivos e para fornecer orientações e informações aos pais sobre a evolução da criança, cujo seguimento deve ser contínuo e sistemático, realizado por uma equipa interdisciplinar
Autoeficácia materna na amamentação de recém-nascidos pré-termo
No full textEste estudo insere-se no domínio da psicologia clínica da gravidez e da maternidade, focando-se na amamentação segundo uma visão interaccionista e transdisciplinar, e debruçando-se, como objecto de estudo, sobre o constructo da autoeficácia materna na amamentação de bebés pré-termo e ou doentes. Partindo da importância da amamentação para todo o ciclo de vida humano e com base na revisão de literatura, esta investigação teve como objectivos: investigar a perceção materna da autoeficácia na amamentação de recém-nascidos pré-termo e ou doentes no segundo dia após o parto, contribuir para a adaptação e validação da Breastfeeding Self-Efficacy Scale (Short Form) for Mothers of Ill or Preterm Infants (Wheeler & Dennis, 2013) para a língua Portuguesa, avaliar o poder explicativo dos fatores sociodemográficos e clínicos relativamente à perceção materna da autoeficácia na amamentação e oferecer uma proposta de um programa de intervenção clínica para assessoria às mães e aos bebés pré-termo em amamentação. A amostra incluiu 98 mães de bebés pré-termo e sete mães de bebés doentes (N = 105). Foi aplicado um Questionário Sociodemográfico e Clínico, seguido da BSES-SF for Mothers of Ill or Preterm Infants (Wheeler & Dennis, 2013) na versão para a língua Portuguesa (BSES-SF-VP) no segundo dia após o parto. Os resultados obtidos na análise de consistência interna da BSES-SF-VP mostraram um coeficiente alfa de Cronbach de .92 e as pontuações totais da escala identificaram uma média de 71.23. Uma percentagem importante da variância da autoeficácia materna na amamentação foi explicada pela experiência anterior na amamentação, pelos aspetos sociodemográficos maternos (escolaridade e nacionalidade) e pela história clínica da última gestação (ajuda médica para engravidar, problemas de saúde física na gravidez e tipo de gravidez). Supomos que a BSES-SF-VP seja um instrumento importante que possibilita reconhecer as expetativas em relação à amamentação, permitindo a elaboração de estratégias individuais para um trabalho de assessoria e apoio nesta prática.This study falls within the field of clinical psychology of pregnancy and motherhood, focusing on breastfeeding according to an interactionist and transdisciplinary vision, and focusing, as an object of study, on the construct of maternal self-efficacy in breastfeeding of preterm and/or sick infants. Starting from the importance of breastfeeding for the entire human life cycle and based on the literature review, this research aimed to investigate the maternal perception of self-efficacy in breastfeeding preterm newborns and/or patients on the second day after birth,
contribute to the adaptation and validation of the Breastfeeding Self-Efficacy Scale (Short Form) for Mothers of Ill or Preterm Infants (Wheeler & Dennis, 2013) for the Portuguese language (BSES-SF-VP), to evaluate the explanatory power of the sociodemographic and clinical factors relative to maternal perception of breastfeeding self-efficacy and to offer a proposal for a clinical intervention program to provide advice to mothers and preterm infants while breastfeeding. The sample included 98 mothers of preterm infants and seven mothers of sick infants (N = 105). A Sociodemographic and Clinical Questionnaire was applied, followed by the BSES-SF for Mothers of Sick or Preterm Infants (Wheeler & Dennis, 2013) in the Portuguese version (BSES-SF-VP) on the second day after birth. The results obtained in the internal consistency analysis of the BSES-SF-VP showed a Cronbach's alpha coefficient of .92 and the total scale scores identified an average of 71.23. An important percentage of the variance of maternal self-efficacy in breastfeeding was explained by previous breastfeeding experience, maternal sociodemographic aspects (education and nationality) and clinical history of the last pregnancy (medical help to get pregnant, physical health problems during pregnancy and type of pregnancy). We assume that the BSES-SF-VP is an important instrument that makes it possible to recognize expectations regarding breastfeeding, allowing the development of individual strategies for advisory and support work in this practice
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
