    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

    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

    Microempresas e empresas de pequeno porte sob o enfoque da análise econômica do direito e da função social do Estado

    As microempresas e empresas de pequeno porte correspondem a 99% do número de estabelecimentos empresariais no Brasil, e são responsáveis por 52% de todos os empregos formais no país. Diante da posição protagonista deste setor empresarial na geração de empregos, renda e para o desenvolvimento econômico nacional, este artigo tem por objetivo analisar as microempresas e empresas de pequeno porte sob duplo enfoque: da Análise Econômica do Direito e da Função Social do Estado. Por meio desta dupla perspectiva torna possível aferir a imprescindibilidade de uma atuação assertiva do Estado, mediante efetivas políticas públicas de auxílio e incentivo a este segmento empresarial. Trata-se de um imperativo de sobrevivência econômica e condição fundamental para garantia do pleno emprego e do desenvolvimento econômico do país. E mais, constitui um comando constitucional de caráter conformador e impositivo, que justifica a reivindicação pela realização de políticas públicas por parte do Estado, indo ao encontro da sua função social prevista constitucionalmente. Para tanto, utilizou-se, no desenvolvimento da presente pesquisa, o método indutivo, operacionalizado pelas técnicas da pesquisa bibliográfica, com a utilização de indicadores econômicos, além dos estudos econômicos e também marcos normativos

    Inteligência Artificial e Direitos Fundamentais no Brasil: Uma Análise sobre Vieses Algorítmicos, Transparência Decisória e o Projeto de Lei 2338/2023: Inteligência Artificial e Direitos Fundamentais no Brasil

    The general objective of this article is to critically analyze the impacts of the implementation of artificial intelligence systems in the sphere of fundamental rights in Brazil, focusing on algorithmic biases, the transparency of decision-making processes and the adequacy of Brazilian Bill nº. 2338/2023. The following specific objectives were listed: a) mapping some AI models used in Brazil and around the world, and which have the potential to interferewith fundamental rights, such as privacy, equality, and due legal process; b) examine cases of algorithmic biases identified in AI systems, illustrating their consequences on vulnerable groups; c) evaluate the Brazilian regulatory - Bill2338/2023, and its possibility of guaranteeing a safe and ethical environment for the use of these technologies in Brazil. The present study is justified given the accelerated growth in the use of AI in various spheres of social,  economic and legal life in Brazil. The lack of robust regulation and the risk of perpetuating discrimination through algorithmic systems require an in-depth and criticalanalysis to ensure that fundamental rights are protected. The methodology used is exploratory and descriptive in nature, addressing practical cases and, also, as a technical procedure, bibliographic research was used. O presente artigo tem por objetivo geral analisar criticamente os impactos da implementação de sistemas de inteligência artificial na esfera dos direitos fundamentais no Brasil, com foco nos vieses algorítmicos, na transparência dos processos decisórios e na adequação do Projeto de Lei brasileiro nº 2338/2023. Foram elencados como objetivos específicos os seguintes: a)mapear alguns modelos de IA utilizados no Brasil e no mundo, e que têm potencial de interferir em direitos fundamentais, como a privacidade, igualdade, e o devido processo legal; b) examinar os casos de vieses algorítmicos identificados em sistemas de IA, ilustrando suas consequências sobre  grupos vulneráveis; c) avaliar o projeto de regulamentação brasileiro – o Projeto de Lei 2338/2023, e sua possibilidade de garantir um ambiente seguro e ético para o uso dessas tecnologias no Brasil. O presente estudo se justifica diante do crescimento acelerado do uso de IA em diversas esferas da vida social, econômica e jurídica no Brasil. A ausência de regulamentação robusta e o risco de perpetuação de discriminações, através de sistemas algorítmicos, demandam uma análise aprofundada e crítica para garantir que os direitos fundamentais sejam protegidos. A metodologia utilizada tem natureza exploratória e descritiva,  abordando casos práticos e, também, como procedimento técnico, utilizou-se de pesquisa bibliográfica.
