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 gestão ambiental e a zona costeira: como operar nesta área complexa, onde se sobrepõem tantos usos e conflitos
Get PDFA Zona Costeira, área de transição, é a interface entre os meios aquático, terrestre e aéreo. Compreende ecossistemas interligados, exibindo elevada produtividade. Como conseqüência, exerce forte atratividade às sociedades humanas do planeta, o que condicionou intensa ocupação e explotação dos recursos. Os fatores de pressão são numerosos, com diferentes setores sociais disputando seus recursos. Como estes estão distribuídos assimetricamente na natureza e na sociedade, apenas grupos hegemônicos usufruem do fácil acesso a esses bens e serviços. É fato que atividades humanas promovem impactos de dimensões variadas, com conseqüências que afetam comunidades locais e remotas, gerando problemas ambientais. A gestão ambiental desponta como estratégia de mediação entre diferentes atores em conflito, buscando conciliar interesses, democratizar direitos sociais e sensibilizar grupos quanto aos limites naturais da sustentabilidade ecológica e econômica. Para operá-la, o gestor emprega mecanismos que viabilizam procedimentos fundamentais do direito público e privado. A Educação Ambiental enfoca princípios humanísticos, holísticos, democráticos e participativos. Considera o pluralismo de idéias, vincula ética, educação, trabalho e práticas sociais, caracterizando-se como ferramenta fundamental do processo de gestão. Trabalha não apenas como transmissora do conhecimento, mas promovendo mobilização social, incorporando valores éticos na relação com o Meio Ambiente, para que todos tenham direito a usufruir de plena cidadania
Diagnóstico da malacocultura catarinense em apoio à gestão costeira: subsídios ao zoneamento da atividade, ordenamento pesqueiro, licenciamento ambiental e a autorização de uso do espaço físico marinho em àguas de domínio da união
Get PDFTese (doutorado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-Graduação em Engenharia AmbientalNeste estudo procurou-se diagnosticar a situação do cultivo de moluscos bivalves marinhos (malacocultura) no litoral catarinense, em apoio à gestão costeira. A pesquisa considerou as relações entre a malacocultura e a ocupação do espaço marinho-costeiro, os impactos ambientais que promove e sofre, as oportunidades sócio-econômicas que proporciona, as questões relacionadas à saúde pública e aos conflitos resultantes de sua expansão. Os seguintes objetivos foram estabelecidos: (a) obter e analisar parâmetros físico-químicos e biológicos da água do litoral catarinense para disponibilizá-los como indicadores de qualidade ambiental; (b) descrever a evolução do processo de planejamento e expansão da malacocultura catarinense entre 1995 e 2005 e dimensionar a área total operacionalizada pela atividade até 2005; (c) definir o percentual de ocupação superficial das baías e enseadas catarinenses em 2005; (d) localizar e analisar a situação legal das áreas aqüícolas marinho-estuarinas catarinenses; (e) identificar as principais legislações internacionais e nacionais que têm relação com a atividade de malacocultura e; (f) descrever o processo histórico do ordenamento da atividade e os passos para sua regularização no Brasil. A metodologia utilizada empregou dados de monitoramento ambiental, a análise histórica do desenvolvimento da atividade e da legislação correlata, bem como comparou os dados de áreas aqüícolas vistoriadas em relação àqueles declarados ao Termo de Ajustamento de Conduta. Os resultados demonstraram haver localidades inadequadas à atividade, devido ao descumprimento da legislação ou por condições ambientais indesejáveis. Em 2005, cerca de 506 hectares encontravam-se efetivamente utilizados. O setor Centro foi o de maior concentração, com 49,63% do espaço marinho ocupado (aproximadamente 251,47 hectares), seguido pelo Centro-Norte, com 43,68% do total (cerca de 221,31 hectares). A análise da evolução do processo de expansão da atividade apontou problemas relacionados à falta de planejamento, com conseqüências ao meio ambiente, riscos à saúde pública, prejuízos aos maricultores e outros segmentos, como navegação, pesca, Unidades de Conservação e o turismo. In this study we tried to diagnose the situation of the cultivation of sea bivalve mollusks (mollusks culture) along Santa Catarina's coast, in support to the coastal administration. The research considered the relationships between the mollusks culture and the occupation of the marine-coastal space, the environmental impacts that it promotes and it suffers, the socioeconomic opportunities that it provides, the subjects related to the public health and to the resulting conflicts of this expansion. The following objectives were established: (a) to obtain and to analyze physiochemical and biological parameters of the coastal catarinense's water to make available them as indicators of environmental quality; (b) to describe the evolution of the planning process and expansion of the malacocultura in Santa Catarina between 1995 and 2005 and to measure the total area used for the activity up to 2005; (c) to define the percentile of superficial occupation of the estuaries in 2005; (d) to locate and to analyze the legal situation of the cultivation of mollusks areas along Santa Catarina's coast; (e) to identify the main international and national legislations that they have relationship with the mollusks culture and; (f) to describe the historical legal process of the activity and the steps to solve the legal problems in Brazil. The methodology used data of environmental conditions, the historical analysis of the development of the activity and of the legislation it correlates, as well as it compared data of the sea areas inspected in relation to the declared to the Term of Adjustment of Conduct. The results demonstrated there to be inadequate places to the activity, due to the noncompliance of the legislation or for undesirable environmental conditions. In 2005, about 506 hectares they were indeed used. The section Center was it of larger concentration, with 49,63% of the busy sea space (about 251,47 hectares), following for the Center-north, with 43,68% of the total (about 221,31 hectares). The analysis of the evolution of the process of expansion of the activity pointed problems related to the planning lack, with consequences to the environment, risks to the public health, damages to the workers of the sea and other segments, as navigation, Units of Conservation and the tourism
