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
Modelagem fuzzy para avaliação de desempenho ambiental do gerenciamento de resíduos sólidos industriais
No full textEsta Tese desenvolveu um instrumento para avaliação de desempenho ambiental no gerenciamento de resíduos sólidos industriais. A verificação das práticas considera o transcurso do ciclo de vida do produto por meio de indicadores e índices tendo como parâmetros alicerçadores a Política Nacional de Resíduos Sólidos e conceitos afins, como a logística reversa, a Produção mais Limpa e o Ecodesign, além de normas da série ISO 14000 tais como Sistemas de Gestão Ambiental, Integração de aspectos ambientais no projeto e desenvolvimento de produtos, Rotulagem ambiental e Avaliação de Desempenho Ambiental. O objetivo central da Tese, que foi desenvolver um modelo para avaliação de desempenho ambiental, esta contido neste panorama, o qual recorreu aos recursos da modelagem fuzzy a fim de assessorar as organizações na tomada de decisões. A metodologia, de natureza qualitativa e quantitativa, embasou a construção do instrumento denominado Índice de Desempenho Ambiental da Gestão de Resíduos Sólidos Industriais (IDEA PNRS+L). Este se constitui de 26 indicadores e 23 índices, concebido na forma top-down soft decision tree. O cálculo dos índices, compostos de regras fuzzy, variáveis e suas inferências, incluiu a visão de um grupo de especialistas, em pesquisa de opinião, para ajustar os graus de influência das variáveis de cada índice. Nas simulações, testes e aplicação do instrumento em uma indústria para avaliar as suas potencialidades, o IDEA PNRS+L mostrou-se sensível, mesmo para pequenas variações dos dados de entrada, plausível e confiável, ao reproduzir o comportamento estabelecido em sua concepção. Os parâmetros alicerçadores que constituíram o corpo teórico, concluindo, foram assaz abrangentes e permitiram a construção do instrumento de avaliação de desempenho ambiental IDEA PNRS+L, considerado adequado para a arbitragem das organizações. Concomitantemente, foram recuperadas as normas, concepções de iniciativas governamentais e atitudes profissionais ambientalmente corretas apoiadas em conceitos vanguardistas de produtos e serviços.This Thesis develops an instrument for evaluating environmental performance in management of industrial solid waste. The practices verification consider the industrial product life-cycle through indicators and indices based on the National Policy on Solid Waste parameters and related concepts such as reverse logistics, Cleaner Production and Ecodesign, and standards like ISO 14000 series such as environmental management systems, integrating environmental aspects in product design and development, environmental labels and Environmental Performance Evaluation. The central Thesis’ aim, that was to develop an environmental evaluating model, contains this panorama, which calls on a fuzzy modeling tool to assist organizations in making decisions. Two methodological research groups covered the dicussions and the instrument construction called Environmental Performance Index of Industrial Solid Waste Management (IDEA PNRS+L): qualitative and quantitative. This fuzzy modeling is composed of 26 indicators and 23 index, conceived in top- down soft decision tree form. The index calculation - composed of fuzzy rules, variables and their inferences - included a group of specialists respondents view, through a survey, to adjust the variables influence degrees of each index. In the simulations, testing and application of the created instrument in an industry to assess their potential, IDEA PNRS+L was sensitive even to small variations of the input data, plausible and reliable, to reproduce the behavior established in the initial configuration. Concluding, the fundamental parameters that formed the theoretical framework were quite comprehensive and allowed the construction of Environmental Performance Evaluation called IDEA PNRS+L, appropriated for industrial arbitration. Simultaneously, the rules, government initiatives concepts and accurated environmentally professional attitudes supported by avant-garde products and services concepts were recuperated
Mapping of the foundry green sand management in the Paraná state from the cleaner production perspective: a contribution to the establishment of strategies
No full textThe environmental issue has been occupying more space on the national scene. The increasing stringency of the laws makes this thematic focus of great attention. In this context, the foundry appears as a great recycler to use recycled material as raw material in their processes, but at the same time has a low environmental performance because it is a huge consumer of mineral resources and also because of the waste it generates. Among this waste, the foundry sand waste is one of the biggest problems concerning the management of waste from the foundry industry. Beyond the theoretical base on foundry, the approach of this study involved aspects of environmental legislation, development of standards specific to the foundry sand through the ABNT CB-59, concepts and environmental management systems (ISO 14001, Industrial Ecology and Cleaner Poduction) searching to analyze the foundry green sand management in the state of Paraná, with a view to establishing future strategies for the sector. To achieve this goal we carried out a survey of the foundry sector across the Parana and identified the companies using the foundry green sand, was diagnosed on the basis of Cleaner Production, the current situation of management of these materials and projected a future scenario of using the technique of molding sand green. The study showed that the management practices of the green sands encompassed three levels of action of Cleaner Production, the use of this material is still interesting to the foundries under the economic aspect and it probably won't be completely replaced. The main goals of the foundries are the expansion of productive capacity and improving product quality. Difficulties have been identified and highlighted the points where there is need for investment and improvements involving organizational and technological levels of companies surveyed. The study also revealed conflicting data between the total generation of discarded foundry sands informed by companies and the estimative based on the input data, leaving it unclear as to the fate of a large part of this material. Therefore, the approach and results of survey showed its relevance to the foundry industry in the State of Paraná, contributing to a better understanding of the green sand management and giving subsidies to the establishment of future strategies.A questão ambiental vem ocupando espaço cada vez maior no cenário nacional, crescente aumento no rigor das legislações torna essa temática foco de grande atenção. Nesse ínterim, a indústria da fundição surge como grande recicladora, por utilizar material reciclado como matéria-prima em seus processos, mas ao mesmo tempo apresenta baixo desempenho ambiental, por ser grande consumidora de recursos minerais e também pelos resíduos que gera. Dentre os resíduos gerados, o de areia de fundição se destaca, constituindo-se num dos maiores problemas no tocante ao gerenciamento de resíduos da indústria de fundição. Além do embasamento sobre fundição, a abordagem deste trabalho envolveu aspectos da legislação ambiental, elaboração de normas específicas para as areias de fundição através da ABNT CB-59, conceitos e sistemas de gerenciamento ambiental (ISSO 14001, Ecologia Industrial e Produção mais limpa), buscando analisar o gerenciamento das areias a verde de fundição no Estado do Paraná com vistas ao estabelecimento de futuras estratégias para o setor. Para atingir esse objetivo realizou-se um levantamento do setor de fundição em todo o Paraná e identificaram-se as empresas utilizadoras de areias à verde de fundição; diagnosticou-se, com base na Produção mais limpa, a atual situação do gerenciamento desses materiais e projetou-se um cenário futuro da utilização da técnica de moldagem por areias a verde. O estudo mostrou que as práticas de gerenciamento das areias a verde englobaram os três níveis de ação da Produção mais limpa, que o uso desse material continua sendo interessante para as fundições sob o aspecto econômico e que dificilmente será substituído totalmente. Como principais metas das fundidoras foram apontadas a expansão da capacidade produtiva e a melhoria na qualidade dos produtos. Foram identificadas as dificuldades enfrentadas e evidenciados pontos em que há necessidade de investimentos e melhorias envolvendo o nível organizacional e tecnológico das empresas pesquisadas. O estudo também revelou dados conflitantes entre a geração total de areias descartadas de fundição informada pelas empresas e a geração estimada com base nos dados de entrada, deixando dúvidas quanto ao destino de grande parcela desse material. Portanto, a abordagem e os resultados obtidos na pesquisa evidenciaram sua relevância para o setor de fundição no Estado do Paraná, contribuindo para um melhor conhecimento sobre o gerenciamento das areias a verde e dando subsídios ao estabelecimento de futuras estratégias
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
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
