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
Modelo lógico para análise de políticas públicas em perspectiva histórica
No full textThis paper proposes a hypothetical representation of a policy seen in historical perspective. The modernization of the city of Porto Alegre, in the south of Brazil, from the end of the 1920s until 1937 was the empirical object of the author's PhD thesis in Urban and Regional Planning. Here we highlight its methodological framework, namely a logical model developed at the Institute for Applied Economic Research (Ipea), here applied for the outline of an urban circulation problem/program. Such configuration includes the three components of the logical model: an explanation of the problem and the program's basic references; the program's structuration towards the achievement of desired outcomes; and the identification of relevant factors of context. We sought evidence for the representation of the three components in historical sources, which have also supported a vulnerability analysis of the program's logical model. Such analysis permits to explain why the program's structuration would not have allocated the most adequate treatment to the problem's causes. We finally present considerations on retrospective uses of the logical model, which may aggregate knowledge on concrete acts of policy implementation in the past, in order to provide more robust explanations of problems that persist and must be tackled by new programs in the present
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
Transferências Voluntárias da União: uma análise dos convênios celebrados pelo Ministério da Saúde na região Norte de 2009 a 2022
Get PDFEssa pesquisa tem como objetivo estudar as Transferências Voluntárias da União – TVUs, por meio de uma análise dos convênios celebrados entre os entes subnacionais situados na região Norte do Brasil com o Ministério da Saúde - MS, no período de 2009 a 2022. A região Norte ocupa uma vasta área do território brasileiro, apresenta a maior hidrografia do mundo, contudo, a região é a menos povoada no Brasil e apresenta o pior índice na universalização do saneamento e abastecimento de água do país. É nesse cenário que se buscou responder como os convênios celebrados pelo Ministério da Saúde contribuíram para o acesso equitativo à água potável e o saneamento. Como metodologia foi utilizada a análise de conteúdo dos convênios, quanto à natureza é qualitativa, de caráter descritivo, com delineamento em pesquisa documental, com recorte para o ano de 2009 a 2022, apoiada na Plataforma Mais Brasil, hoje Transferegov. Assim, a partir de uma abordagem da saúde no âmbito internacional e nacional se fez uma apresentação da relação da saúde e o saneamento básico e do uso equitativo da água para, posteriormente, apresentar uma caracterização dos convênios por estado a partir da sua relação com os municípios, população e o empenho de recursos acumulados por Emenda Parlamentar e Programa/Ação por estados e municípios agrupados por IDHM. A pesquisa evidenciou o papel importante dos serviços de Melhorias Sanitárias Domiciliares em conjunto com os serviços de Abastecimento de Água no âmbito dos convênios celebrados. Portanto, as TVUs instrumentalizadas por meio dos convênios analisados, em conjunto, se caracterizam como um esforço que visa a promoção da política pública destinada à mobilização da universalização do saneamento e do abastecimento de água na região Norte.This research aims to study the Union Voluntary Transfers - TVUs, through an analysis of the agreements signed with the Ministry of Health - MS, from 2009 to 2022, in the North region of Brazil. The North region occupies a vast area of the Brazilian territory, has the largest hydrography in the world, however, the region is the least populated in Brazil and has the worst index in the universalization of sanitation and water supply in the country. It is in this scenario that we sought to answer how the agreements signed by the Ministry of Health contributed to equitable access to drinking water and sanitation. As a methodology, the analysis of the content of the agreements was used, in terms of nature, it is qualitative, descriptive in nature, based on documentary research, with a cut for the year 2009 to 2022, supported by the Mais Brasil Platform, today Transferegov. Thus, from an approach to health at the international and national levels, a presentation was made of the relationship between health and basic sanitation and the equitable use of water, in order to subsequently present a characterization of the agreements by state based on their relationship with the municipalities, population and commitment of accumulated resources. The research showed the important role of Home Sanitary Improvement services in conjunction with Water Supply services within the scope of the agreements entered into. Therefore, the TVUs instrumentalized through the agreements analyzed, together, are characterized as an effort aimed at promoting public policy aimed at mobilizing the universalization of sanitation and water supply in the North region
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
Produção social da moradia: um olhar sobre o planejamento da Habitação de Interesse Social no Brasil
Get PDFEste artigo examina a produção social da moradia no Brasil em distintos períodos, ao longo dos últimos cinquenta anos. A partir do enunciado do conceito, verifica-se que a produção social da moradia passou a ganhar espaço e reconhecimento do Estado, estando claros seu planejamento e institucionalização no último período, em que diversos programas habitacionais vieram a financiar esta forma de produção. Uma análise da execução desses programas mostra situações de demanda reprimida, dificuldades operacionais e restrições de fundos, em que os programas sucedem-se, passando o programa Minha Casa Minha Vida, por fim, a concentrar a produção habitacional, inclusive na modalidade voltada às entidades privadas sem fins lucrativos (cooperativas e associações). Enquanto isso, outros instrumentos públicos de planejamento, gestão e financiamento da habitação, incluídos no Sistema Nacional de Habitação de Interesse Social, também criado no período mais recente, e que poderiam ratificar a produção social da moradia, caem em desuso
