Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
Politólogos na imprensa escrita
No full textNeste capítulo apresenta-se uma sistematização da participação
de politólogos na imprensa escrita portuguesa, durante o ano de
2022. Trata-se de um exercício, em formato de relatório, que reflete
o aumento da procura e, por consequência, da confiança da sociedade
civil na Ciência Política enquanto conhecimento especializado
e de interesse para a opinião pública. Neste breve resumo apontamos
as principais tendências de uma análise realizada a 622 artigos
de opinião identificados ao longo do ano. A análise revela conclusões
importantes, contudo o estudo deve ser encarado como ponto de
partida para uma análise anual da produção, seja pelo seu número
como pela escolha de temática em que os politólogos são chamados
a intervir desta forma. Em especial, esta análise pretendeu entender o
papel das várias facetas da qualidade da democracia na participação
dos académicos na imprensa.info:eu-repo/semantics/publishedVersio
Identidade Marítima Portuguesa: Onda Ou Maré? Estudo Comparativo entre o Estado Novo e a Democracia
Full text linkA presente investigação pretende compreender se a narrativa de uma identidade marítima no discurso político português se altera entre os regimes do Estado Novo e o atual período democrático. Embora a própria designação tenha sido utilizada na última década pelos partidos políticos, o imaginário é apresentado como uma visão duradoura e permanente da história portuguesa, cuja promoção se encontra de forma recorrente em toda a sociedade, incluindo trabalhos académicos. O estudo investiga o que se pode designar como as componentes da identidade marítima, assim como avalia se o discurso dos regimes em causa deteve alguma semelhança, tendo em especial consideração a revolução social que marcou a fase de transição. A partir dos principais estudos académicos sobre a identidade e a narrativa, a operacionalização da investigação adota uma veia construtivista. A metodologia do trabalho segue, nessa linha, a prática de análise de discurso, identificando os atores, o contexto e as principais categorias discursivas que compõem a identidade marítima. O papel do mar é contextualizado em ambos regimes para categorizar os principais imaginários a que o discurso político se pode referir. De seguida, o principal contributo do trabalho é analisar, no prisma de uma abordagem do quotidiano do discurso, as intervenções parlamentares em ambos os regimes sobre o mar. Os três períodos de análise representam momentos cruciais para os regimes em estudo e são a VII legislatura da Assembleia Nacional do Estado Novo (1957-1961), a fase de transição (1974-1976, através das Assembleias Nacional, Constituinte e da República) e a XXI legislatura do período democrático (2015-2019). Através de sete palavras-chave – mar; marítimo; marinha, ultramar; ultramarinos; oceano; Atlântico – e seis contextos – político, economia, identidade, defesa, investigação e diversos – identifica-se a evolução do discurso, comparando os três períodos e os dois regimes. As principais conclusões do trabalho identificam o foco da identidade marítima do Estado Novo na legitimação e exploração colonial, enquanto no período democrático o discurso se alastra por mais temáticas, principalmente tentando desenvolver o potencial económico do mar. Enquanto alguns conceitos, como o ultramar, acabaram por desaparecer do discurso, e outros ganharam outros contextos, como o oceano, muitos permaneceram, contudo, na mesma narrativa de uma visão historicista da grandiosidade de Portugal, reforçando o imaginário do mar como metáfora da versão nacional da história. De facto, independentemente de o discurso identificado em democracia ter variado no seu pendor de justificação, as bases narrativas da identidade marítima permaneceram no seu papel de diferenciação da identidade nacional. Embora o estudo tenha as suas limitações, principalmente pelos períodos de análise e contextos abordados, esta conclusão propõe à academia discutir a possibilidade de mecanismos de alteração de narrativas nacionais no futuro. A investigação permite identificar um discurso transformado entre os dois regimes, em que, todavia, a narrativa da identidade marítima permanece e serve como um traço contínuo do contexto português.The goal of this research is to understand if the narrative on the so-called maritime identity in the Portuguese political discourse changes between the regime of the Estado Novo and the current democratic period. Although the expression has been used by political parties in the last decade, the imaginary is presented as an enduring and permanent vision of Portuguese history, whose promotion is easily found in the whole of society, including academic works. The research investigates what this maritime identity may entail as its core components and analyses the discourse of each regime to investigate similarities, giving special attention to the social revolution that marked the phase of transition. Following major works in the fields of identity and narrative, the operationalisation of the analysis adopts a constructive perspective, building on the methodology of discourse analysis. The main actors, the context and the discursive categories of the maritime identity are framed, and both regimes are also contextualized to identify the imaginaries to which political discourse refers. Embracing an analysis of the mundane discourse of everyday politics, this work analyses the parliamentary speeches of three distinct periods, that together shape the picture of both regimes’ perspective on maritime identity. The first period is the VII legislature of the Assembleia Nacional of the Estado Novo (1957-1961), the second is the phase of transition (1974-1976) and spans the Assembleia Nacional, the Constitutional Assembly as well as the start of the Assembleia da República, and the third phase is the last completed legislature of the current democratic period, (XXI, 2015-2019). Seven key words in Portuguese – mar; marítimo; marinha, ultramar; ultramarinos; oceano; Atlântico (roughly sea, maritime, navy, oversea, overseas, ocean, Atlantic) – and six contexts – politics, economy, identity, defence, research, and others – collectively identity the evolution of the political discourse and allow for a qualitative comparison between the periods and regimes. The main conclusions identify that during the Estado Novo the focus of the maritime identity was in justifying the colonial empire, both in terms of exploitation and legitimacy, while the democratic regime focusses its discourse on a larger array of themes, mostly in regard to the potential economic development of the sea and its resources. While some concepts, like ultramar, cease to exist in the discourse, and others gained thematic relevance, like oceano, many remained in the same historicist narrative on the greatness of Portugal, reinforcing the sea as a metaphor for Portuguese national history. Even though the discourse changed in the sense of justification to appeal to the democratic regime, the base narrative remained as a factor of identitarian differentiation. While this study has some limitations, in its period of analysis and categorisations, the conclusion proposes that future research may discuss the possibility for mechanisms of change in national narratives in the future. The research therefore identifies a transformed discourse between the two regimes but confirms the that the narrative on maritime identity remained a feature of continuity in the Portuguese context
