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
Impactos ambientais da pedreira no município de Caraúbas-RN
Get PDFThe mining is a propulsive activity of the economic development of the country, as well in the touching to social factors, once that is significant source of employment and income; however, resuling in significative impacts to envinromental, affecting the physical, biotic and anthropic environment, these impacts can have beneficial and adverse character. Thereby, it was aimed to identify the main environmental impacts caused by quarry localized in the county of Caraúbas – RN. The search was accompleshed by means of a case study. The methodology consists in two stages, the first one together to population that lives in the area of the surroundings of the quarry, in that was applied 88 questionnaires, with the intent of detecting the envinromental impacts caused by mineral extraction in the region. In the second stage, it was applied 13 questionnaires together to employees, in a way to evaluate the impacts sensed by workers of the enterprise. Still in the scope, it was elaborated quantitative and qualitative matrices for helping in the identification of the impacts genered by activity in
question. As results, among the various identified impacts, those who most stood out were vibrations and noises, with 19,32% and 7,95%, respectively. Stand out yet the problems caused by detonations and explosions coming of the mining activity because in 53,41% of the residences sampled present some kind of damage the its structures. Being that the impacts sensed are contributing directly for the damage in the structure of the residences and the water reservoirs (split and cracks). Besides that, it was verified that 92,31% of the employees think good the security in the enterprise, what contributes for the development of its activities. However, it was found that 23,08% already suffered some kind of work accidente. Thus, it can claim that the mining activity brings social and environmental consequences, such as: noises, vibrations, discomfort and structure damages, and that its execution cause significant
impact to environmental.A mineração é uma atividade propulsora do desenvolvimento econômico do país, como também no tocante aos fatores sociais, uma vez que é significativa fonte de emprego e renda, porém, acarretam impactos significativos ao meio ambiente, afetando o meio físico, biótico e antrópico, estes impactos podem ter caráter benéfico ou adverso. Com isso, objetivou-se identificar os principais impactos ambientais causados pela pedreira localizada no município de Caraúbas- RN. A pesquisa foi realizada por meio de um estudo de caso. A metodologia consiste em duas etapas, a primeira junto à população que vive na área do entorno da Pedreira, em que foram aplicados 88 questionários, com o intuito de detectar os impactos ambientais causados pela extração de minérios na região. Na segunda etapa, aplicou-se 13 questionários junto aos funcionários, de maneira a avaliar os impactos sentidos pelos
trabalhadores do empreendimento. Ainda neste âmbito, elaborou-se matrizes quanti e qualitativas para auxiliar na identificação dos impactos gerados pela atividade em questão. Como resultados, dentre os diversos impactos identificados, os que mais se destacaram foram vibrações e ruídos, com 19,32% e 7,95%, respectivamente. Destacam-se ainda os problemas causados pelas detonações e explosões advindas da atividade mineradora, pois em 53,41 % das residências amostradas apresentam algum tipo de dano as suas estruturas. Sendo que os impactos sentidos estão contribuindo diretamente para os danos na estrutura das residências e aos reservatórios d’água (trincas e rachaduras). Além disso, verificou-se que 92,31% dos funcionários acham boa a segurança na empresa, o que contribui para o desenvolvimento de suas atividades. Entretanto, constatou-se que 23, 08% já sofreram alguém tipo de acidente de trabalho. Desta forma, pode-se afirmar que a atividade mineradora traz consigo consequências socioambientais, como: ruídos, vibrações, desconforto e danos estruturais, e que sua execução causa impacto significativo ao meio ambiente.Trabalho não financiado por agência de fomento, ou autofinanciad
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
Viabilidade ambiental na indústria de envase de água mineral
Get PDFThe extraction of mineral water has been leveraged in recent years due to the properties present in its composition and the benefits associated with human health. With this, the objective of this work was to verify the environmental viability of the implantation of a mineral water container industry in Icapuí/CE. The study was carried out based on the identification of environmental impacts. A matrix cell was used to classify the impacts arising from the installation and operation phase of the enterprise in terms of character, order, magnitude and duration, and thus propose mitigating measures to mitigate the environmental impacts listed and then apply good environmental practices within the stages of the company's production process. Therefore, from the survey, we listed 26 impacts, among which we have: decharacterization of the landscape, suppression of the vegetation cover, removal of some specimens of the fauna, besides the use of local labor and the generation of employment and income. In order to mitigate these adverse effects, it was possible to present some mitigating measures such as: to elaborate the monitoring and management program of the fauna, to carry out deforestation only in the useful area for the project, as well as training and skills that enhance the activities developed by the company. Already as an application of good environmental practices it was possible to suggest the following techniques: partnerships with recycling cooperatives, supplying the bottles as raw material for other productive processes, such as using the water for irrigation of the green area and supplying the boxes of the bathrooms
. Therefore, the environmental feasibility studies of an enterprise are of fundamental importance, since it was possible to predict the adverse effects of the activity in the environmental compartments and consequently to expose mitigating measures and good environmental practices that make possible the installation and operation of the water container industry mineral.A extração de água mineral tem alavancado nos últimos anos em virtude das propriedades presentes em sua composição e os benefícios associados a saúde humana. Com isso, o objetivo deste trabalho foi verificar a viabilidade ambiental da implantação de uma indústria de envase de água mineral em Icapuí/CE. O estudo foi realizado a partir da identificação dos impactos ambientais. Foi preenchida uma célula da matriz buscando classificar os impactos decorrentes da fase de instalação e operação do empreendimento quanto ao caráter, ordem, magnitude e duração, e assim propor medidas mitigadoras para atenuar os impactos ambientais elencados e em seguida aplicar boas práticas ambientais dentro das etapas do processo produtivo da empresa. Portanto, a partir do levantamento foram listados 26 impactos, dentre os quais temos: descaracterização da paisagem, supressão da cobertura vegetal, afastamento de alguns espécimes da fauna, além do aproveitamento de mão-de-obra local e a geração de emprego e renda. Visando amenizar esses efeitos adversos, foi possível apresentar algumas medidas mitigadoras como: elaborar o programa de monitoramento e manejo da fauna, realizar o desmatamento somente na área útil para o empreendimento, além de treinamento e capacitações que potencializem as atividades desenvolvidas pela empresa. Já como aplicação de boas práticas ambientais foi possível sugerir as seguintes técnicas: parcerias com cooperativas de reciclagem, fornecimento dos garrafões como matéria-prima para outros processos produtivos, como por exemplo, utilizar a água para irrigação da área verde e abastecer as caixas dos banheiros. Por isso, os estudos de viabilidade ambiental de um empreendimento são de fundamental importância, pois assim foi possível prever os efeitos adversos da atividade nos compartimentos ambientais e consequentemente expor medidas mitigadoras e boas práticas ambientais que viabilizem a instalação e operação da indústria de envase de água mineral.Trabalho não financiado por agência de fomento, ou autofinanciad
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
