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
A escravidão contemporânea no sistema capitalista: um instrumento econômico.
Get PDFA utilização de mão de obra escrava é algo que ocorre no Brasil desde o início de sua colonização. A Lei Áurea, sancionada em 1888, embora represente um grande marco na abolição da escravidão no país, não acabou com todas as formas de escravidão e exploração de mão de obra no Brasil. Apesar de não ter sido reconhecida por lei durante muito tempo, a escravidão contemporânea é presente de maneira muito forte em diversos países do mundo, incluindo o Brasil. Isso não significa, no entanto, que a escravidão contemporânea pode ser resumida como a herança da escravidão colonial. Dentro do contexto capitalista atual, muitas empresas se abstêm da transparência e da fiscalização de onde suas matérias primas vêm e possibilitam a existência da escravidão contemporânea em suas cadeias produtivas. Além disso, o combate à escravidão contemporânea na governança global raramente trata deste problema como algo inerente ao modelo econômico capitalista contemporâneo, o que resulta em um combate altamente ineficienteThe use of slave labour happens in Brazil ever since the beginning of the country’s colonization. The ‘Lei Áurea’, sanctioned in 1888, though it represents a huge milestone in slavery abolition in the country, didn’t finish all forms of slavery and labour exploitation in Brazil. Even though it was not recognized formally for a long time, modern slavery is strongly present in a lot of different countries in the world, including Brazil. That does not mean, though, that modern slavery can be referred to as just a legacy from the old colonial slavery system. In the current capitalist context, a lot of companies refrain themselves from transparency and inspection of where their materials come from and make the existence of modern slavery on their supply chains possible. Adding to that, modern slavery combat in global governance rarely treats this problem as something inherent to the contemporary capitalist economic system, which results in a highly inefficient comba
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
Entrave mexicano: ciclo de violações contra mulheres migrantes do Triângulo Norte
Get PDFEsta pesquisa tem como propósito analisar o ciclo de violações que vivenciam mulheres provenientes do Triângulo Norte no território mexicano, cujos entraves têm influenciado o surgimento e atuação de diversos atores legais e ilegais no que tange esta travessia, dificultando-a para que não ocorra de forma consentida. Ao fazer isso, o efeito não se traduz no interrompimento das migrações, mas faz com que elas ocorram às margens, de forma precária, envoltas por inúmeros riscos e com custos muito altos. Este cenário atinge de forma particular as mulheres, já que ao longo da trajetória elas experienciam diversas formas de violência. A pesquisa baseou-se em uma extensa revisão bibliográfica e tem como recorte temporal meados dos anos 2000 e a década de 2010, período no qual observa-se um aumento na militarização das fronteiras. Ao longo da pesquisa, o argumento central é de que estas forças, tanto lícitas quanto ilícitas, atuam de forma paralela com o objetivo de frear os deslocamentosThis paper aims to analyze the cycle of violations which women from the Northern Triangle experience in Mexican territory, whose hindrances have influenced the emergence and action of several legal and illegal actors regarding this crossing, making it difficult in order to not let it occur in a consensual way. By doing so, the effect is not translated into the interruption of migrations, but causes them to occur on the margins, in a precarious way, surrounded by countless risks and taking very high costs. This scenario affects women in a very particular manner, as they experience different forms of violence along the path. The research took basis on an extensive bibliographic review and has as a time frame the mid-2000s and the 2010s, a period in which an increase in the militarization of borders is observed. Throughout the research, the main argument is that these forces, both licit and illicit, act in parallel with the aim of curbing displacement
Bitcoin como política monetária e de desenvolvimento nacional: O caso de El Salvador
No full textEm setembro de 2021, El Salvador, um país da américa latina, dá oficialmente curso legal à criptomoeda mais famosa do mundo, o Bitcoin, tornando nacionalmente legal a utilização da criptomoeda como método de pagamentos e transações financeiras. O caso de El Salvador é o primeiro experimento da funcionalidade do sistema Bitcoin na vida cotidiana e seu sucesso influenciará sua futura difusão e adoção global. O Bitcoin pode funcionar como método de pagamento assim como outras moedas fiduciárias como o dólar ou o euro? Neste trabalho é analisado através de pesquisas e desenvolvimento teórico a funcionalidade da criptomoeda até os dias atuais, assim como a capacidade dela de agregar efetivamente partes da sociedade que estão a margem da inclusão econômica no país. É discutido também o papel da criptomoeda na atual situação do país frente o Sistema Internacional, tal qual a postura das grandes instituições internacionais e das grandes potências globais frente a mudança aderida pelo paísIn September 2021, El Salvador, a country in Latin America, officially gives legal tender to the most famous cryptocurrency in the world, Bitcoin, making the use of cryptocurrency as a method of payments and financial transactions nationally legal. The case of El Salvador is the first experiment of the functionality of the Bitcoin system in everyday life and its success will influence its future diffusion and global adoption. Can Bitcoin work as a payment method like other fiat currencies like the dollar or the euro? This work analyzes, through research and theoretical development, the functionality of cryptocurrency up to the present day, as well as its ability to effectively aggregate parts of society that are on the margins of economic inclusion in the country. The role of cryptocurrency in the current situation of the country in relation to the International System is also discussed, as well as the position of the great international institutions and the great global powers in the face of the change adhered to by the countr
A diplomacia cultural do Japão como um instrumento anti-memória: um estudo de caso sobre os filmes “Meu amigo totoro” e “Túmulo dos vagalumes”
Get PDFA exportação dos produtos culturais japoneses, sobretudo os filmes, a fim de alterar a percepção do país dá corpo à diplomacia cultural. Esse tipo de diplomacia para atingir seu objetivo de transmitir uma imagem positiva diante da comunidade internacional, contribui para o efeito de amnésia em relação ao passado imperialista do Japão. O caso do soft power japonês revela os desafios em projetá-lo uma vez que as memórias de guerra são contestadas no âmbito doméstico. Sendo a memória ligada à identidade nacional, o Japão se encontra na ambiguidade. Ainda assim, as imagens projetadas pelos filmes criam um imaginário capaz de induzir a admiração e modelar as percepções de uma naçãoThe export of Japanese cultural products, especially films, in order to change the perception of the country embodies cultural diplomacy. This kind of diplomacy as a means to achieve its goal of conveying a positive image towards the international community contributes to the effect of amnesia regarding Japan's imperialist past. The case of Japanese soft power unveils the challenges in projecting it, considering that war memories are contested domestically. Since memory is linked to national identity, Japan finds itself trapped in ambiguity. Even so, the images projected by the films create an imaginary capable of inducing admiration and shaping the perceptions of a natio
