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
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

A química dos plásticos: impactos e conscientização na educação básica
No full textIn chemistry teaching, the aim is to mediate the learning of concepts and theories, using students' previous knowledge as a basis for developing scientific knowledge, giving it concreteness and intelligibility. The use of synthetic polymers, especially plastic materials, is very important in this context because, as they are part of everyday life, these materials permeate students' knowledge and make it possible to contextualize various contents. In addition, these materials have properties such as Iightness, water resistance and malleability, which are indispensable in contemporary life. However, excessive consumption and improper disposal result in serious environmental problems, since they require a long time to degrade in nature. Thus, this research aims to identify what contributions a didactic practice using recyclable plastics, to be carried out with students from two secondary school classes in a state school in the municipality of São Mateus-ES, can bring to the understanding of chemistry content and to the development of environmental awareness about the impacts caused by the inappropriate disposal of these materials. To this end, the methodology of this research is based on a qualitative analysis, initially of an exploratory nature, through the application of a questionnaire, analyzed mainly through the method of descriptive statistical analysis, then with the execution of a Didactic Sequence, described and analyzed through the reports of the researcher's Iogbook, and finally with a semi-structured interview, analyzed through the method of content analysis proposed by Bardin (2011). The results indicated that, after the Didactic Sequence, the participants began to better understand the different types of plastics and their environmental impacts, as well as establishing connections between the chemistry content and its use in everyday life. In short, the didactic practice was effective in broadening the students' knowledge and promoting critical awareness of the importance of recycling and the proper disposal of plastic materials.No ensino de Química, busca-se mediar o aprendizado de conceitos e teorias, utilizando-se os conhecimentos prévios dos estudantes como base para o desenvolvimento de saberes científicos, conferindo-lhes concretude e inteligibilidade. O emprego de polímeros sintéticos, especialmente dos materiais plásticos, apresenta grande relevância nesse contexto, pois, por integrarem o cotidiano, esses materiais permeiam os saberes dos estudantes e possibilitam a contextualização de diversos conteúdos. Além disso, esses materiais possuem propriedades, como leveza, resistência à água e maleabilidade, que são indispensáveis na vida contemporânea. Contudo, o consumo excessivo e o descarte inadequado resultam em graves problemas ambientais, uma vez que exigem um longo tempo para serem degradados na natureza. Assim, esta pesquisa objetiva identificar quais contribuições uma prática didática utilizando os plásticos recicláveis, a ser realizada com estudantes de duas turmas da segunda série do Ensino Médio, de uma escola estadual do municipio de São Mateus-ES, pode trazer para compreensão de conteúdos de Química e para o desenvolvimento da percepção ambiental acerca dos impactos causados pelo descarte inapropriado destes materiais. Para isso, a metodologia desta pesquisa parte de uma análise qualitativa, inicialmente, de cunho exploratório, por meio da aplicação de um questionário, analisado majoritariamente por meio do método de análise estatística descritiva, em seguida, com a execução de uma Sequência Didática, descrita e analisada por meio dos relatos do diário de bordo da pesquisadora, e, por fim, com uma entrevista semiestruturada, analisada por meio do método de análise de conteúdo proposto por Bardin (2011). Os resultados indicam que, após a Sequência Didática os participantes passaram a compreender melhor os diferentes tipos de plásticos e seus impactos ambientais, além de estabelecerem conexões entre os conteúdos de Química e o seu uso no cotidiano. Em suma, a prática didática foi eficaz para ampliar o conhecimento dos estudantes e promover conscientização crítica sobre a importância da reciclagem e do descarte adequado de materiais plásticos
Caminhos para a gestão escolar: uma análise das práticas e desafios no contexto educacional público
No full textHis study addresses the challenges and perspectives of school management in public schools, highlighting the essential role of managers in the organization and functioning of educational institutions. Based on the analysis of data collected through questionnaires applied to ten principals of public schools in São Mateus/ES, the work investigates how managers face the main obstacles in their roles and identifies practices that can contribute to school management, promoting quality education based on the principles of democratic management. The results show that although managers play a central role in coordinating teaching staff, students and the school community, they face significant challenges, such as a lack of financial resources, an overload of administrative tasks and resistance to change. These factors limit the autonomy of managers and hinder the implementation of innovative and effective practices. Despite this, the responses obtained highlight positive aspects, such as the possibility of promoting collaborative actions, training teachers and engaging the community. The conclusion is that balance in the choices made by managers, combined with ethical and collaborative leadership, is essential to overcome challenges and promote an inclusive and transformative educational environment. Furthermore, an analysis of the responses shows that there is a need for greater autonomy and support for managers so that they can carry out their role more effectively and in line with the contemporary demands of education.Este estudo aborda os desafios e as perspectivas da gestão escolar em escolas públicas, destacando o papel essencial dos gestores na organização e funcionamento das instituições educacionais. A partir da análise de dados coletados por meio de questionários, aplicados a dez diretores de escolas públicas em São Mateus/ES, o trabalho investiga como os gestores enfrentam os principais obstáculos de suas funções e identifica práticas que podem contribuir com a gestão escolar, promovendo uma educação de qualidade e fundamentada nos princípios da gestão democrática. Os resultados apontam que, embora os gestores desempenhem um papel central na articulação entre equipe pedagógica, estudantes e comunidade escolar, enfrentam desafios significativos, como a falta de recursos financeiros, a sobrecarga de tarefas administrativas e a resistência às mudanças. Esses fatores limitam a autonomia dos gestores e dificultam a implantação de práticas inovadoras e eficazes. Apesar disso, nas respostas obtidas, destacam-se aspectos positivos, como a possibilidade de promover ações colaborativas, capacitar professores e engajar a comunidade. Conclui-se que o equilíbrio nas escolhas feitas pelos gestores, aliado a uma liderança ética e colaborativa, é essencial para superar os desafios e promover um ambiente educacional inclusivo e transformador. Além disso, a partir da análise das respostas, compreende-se que há a necessidade de maior autonomia e suporte aos gestores para que possam exercer sua função de forma mais eficaz e alinhada às demandas contemporâneas da educação
