Análise da implantação do Parque Aquícola da UHE do Lajeado através de métodos multicritérios de decisão – Uma abordagem socioambiental e dos fatores de risco
This study is derived from the policy of the Brazilian government to increase fish production through the promotion of fish farming in network ponds in aquaculture parks. This project aims to explore the implementation and operation of the Sucupira Aquaculture Park (PAS) of the Lajeado Hydroelectric Power Plant (Palmas / TO) through the use of multicriteria decision methods, aiming at a socioenvironmental approach of the risk factors of the implementation of this project through the proposition of sustainability indicators. Scientometry has demonstrated that the production of knowledge related to fish culture in net tanks and artisanal fishing in reservoirs is indexed and has a multidisciplinary character. The articles are technicist and productivist, with little regard for environmental and socioeconomic factors, nor the public policies for the development and promotion of fishery and fishery activities, which in a way explains the dissatisfaction with the activity by the fish farmers of the Bom Peixe Association , as well as the inefficiency of the public policy of transforming the artisanal fisherman into an entrepreneur. The Social Network Analysis (ARS) makes clear that there is interconnection among all actors, but the protagonism of this network is dominated by public institutions and the process of communication between the various institutional actors is two-way, while between fish farmers and fishermen is of a unidirectional character, making them only subjects of actions. The Trophic State Index (EIT) was used as a monitoring tool for aquaculture activities in PAS. Limnological variables, with the exception of total phosphorus, despite small variations of oxygen and total solids, are in accordance with the recommendations of CONAMA Resolution 357/05. The data allow us to conclude that the aquaculture area presented a predominance of supereutrophic trophic state and that the trophic state of the reservoir in the vicinity of the tanks is strongly influenced by anthropic activities, mainly in the rainy season. In the dry season, there is an increase in the phosphorus concentration in the water, leading to a hypereutrophic state. It is not possible to say that aquaculture is an impactful activity and its effects are difficult to predict in the long term, as well as the behavior of the reservoir through increased production in the parks, however, if there is no monitoring and efficient control over water quality , fish farming may promote degradation of the aquatic ecosystem. The analysis of the technical, economic and financial feasibility of investment in aquaculture projects of tambaqui production in network tanks used the economic indicators Effective Operational Cost (COE), Total Operating Cost (COT), Total Gross Income (RBT), Gross Margin (MB), Net Margin (ML), Profit (L) and Return Rate of Capital (TRC). The analysis of TRC presented negative results and the system of production in excavated nurseries proved to be more efficient. The system of production in network tanks is an alternative of lower cost and time of implantation, but with uncertain return. The socioeconomic profile of the producers is considered to be incompatible with the business and technological activity of aquaculture in network tanks. In the producers' view, the activity is still a future promise and the public policy of turning fishermen into fish farmers proved ineffective. According to TRC, the activity is unsustainable and has been showing negative results, which indicates its low competitiveness. Sustainability and governance indicators were developed for the development of fish farming in the PAS, which, through social, economic and environmental subindices, generated a Sustainability Index (ISUS) of the enterprise. The data allowed to conclude that the ISUS was classified as not very sustainable (0.37), mainly in the economic and social dimensions. The analysis of governance was identified in interviews with the main agents of the productive chain, making it clear that the lack of governance structures was noticeable in all segments analyzed, which portrays the real stage of disorganization and inefficiency of the productive chain of fish farming in PAS.Este estudo deriva da política do governo brasileiro para incremento da produção de pescado por meio do fomento à piscicultura em tanques rede nos parques aquícolas. Este projeto visa explorar a implantação e operação do Parque Aquícola Sucupira (PAS) da UHE Lajeado (Palmas/TO) através do uso de métodos multicritérios de decisão, com objetivo de realizar uma abordagem socioambiental dos fatores de risco da implantação deste empreendimento através da proposição de indicadores de sustentabilidade. A cienciometria, demonstrou que a produção de conhecimento relacionado ao cultivo de peixes em tanques rede e a pesca artesanal em reservatórios está indexada e é de caráter multidisciplinar. Os artigos possuem caráter tecnicista e produtivista, pouco considerando os fatores ambientais e sócio econômicos, nem tampouco as políticas públicas de desenvolvimento e fomento às atividades piscícolas e ou pesqueiras, o que de certa forma explica a insatisfação com a atividade pelos piscicultores da Associação Bom Peixe, bem como a ineficiência da política pública de transformar o pescador artesanal em empreendedor. A Análise de Redes Sociais (ARS) deixa claro que há interligação entre todos os atores, porém o protagonismo dessa rede está dominado por instituições públicas e o processo de comunicação entre os diversos atores institucionais é de caráter bidirecional, enquanto que entre os piscicultores e pescadores é de caráter unidirecional, tornando-os apenas sujeitos das ações. O Índice de Estado Trófico (IET) foi utilizado como ferramenta de monitoramento de atividades aquícolas no PAS. As variáveis limnológicas, com exceção do fósforo total, apesar das pequenas variações de oxigênio e sólidos totais, estão de acordo com as recomendações da Resolução CONAMA 357/05. Os dados permitem concluir que a área aquícola apresentou predominância de estado trófico supereutrófico e que o estado trófico do reservatório nas proximidades dos tanques rede sofre forte influência externa de atividades antrópicas, principalmente no período chuvoso. No período da seca, ocorre aumento na concentração de fósforo na água, levando a um estado hipereutrófico. Não é possível afirmar que a aquicultura seja uma atividade impactante e seus efeitos são difíceis de serem previstos em longo prazo, bem como o comportamento do reservatório mediante aumento de produção nos parques, porém, caso não haja monitoramento e controle eficiente sobre a qualidade da água, a piscicultura pode vir a promover degradação do ecossistema aquático. A análise da viabilidade técnica, econômica e financeira de investimento em projetos aquícolas de produção de tambaqui em tanques rede utilizou os indicadores econômicos Custo Operacional Efetivo (COE), Custo Operacional Total (COT), Renda Bruta Total (RBT), Margem Bruta (MB), Margem Líquida (ML), Lucro (L) e Taxa de Retorno do Capital (TRC). A análise da TRC apresentou resultados negativos e o sistema de produção em viveiros escavados se mostrou mais eficiente. O sistema de produção em tanques rede é uma alternativa de menor custo e tempo de implantação, porém com retorno incerto. O perfil socioeconômico dos produtores é considerado incompatível com a atividade empresarial e tecnificada de aquicultura em tanques rede. Na visão dos produtores a atividade ainda é uma promessa futura e a política pública de transformar pescadores em piscicultores se mostrou ineficaz. De acordo com a TRC, a atividade é insustentável e vem apresentando resultados negativos, o que denota sua baixa competitividade. Foram elaborados indicadores de sustentabilidade e governança para o desenvolvimento da piscicultura no PAS, que através de subíndices sociais, econômicos e ambientais geraram um Índice de Sustentabilidade (ISUS) do empreendimento. Os dados permitiram concluir que o ISUS foi classificado como pouco sustentável (0,37), principalmente nas dimensões econômicas e sociais. A análise de governança foi identificada em entrevistas aos principais agentes da cadeia produtiva, ficando claro que a falta de estruturas de governança foi perceptível em todos os segmentos analisados, o que retrata o real estagio de desorganização e ineficiência da cadeia produtiva da piscicultura no PAS
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
We 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

Author Under Sail The Imagination of Jack London, 1893-1902
In Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
