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
Análise de sistemas integrados e desafios à transição energética global
Full text linkDissertação (mestrado) — Universidade de Brasília, Centro de Desenvolvimento Sustentável, Programa de Pós-Graduação em Desenvolvimento Sustentável, 2024.Esta dissertação trata da transição energética global e seus impactos na redução das
emissões de gases de efeito estufa (GEE) até 2050, com base na aplicação de modelos de
dinâmica de sistemas (system dynamics), como as Calculadoras 2050. A transição
energética é essencial para mitigar as mudanças climáticas e está diretamente ligada à
evolução histórica da matriz energética, caracterizada por uma dependência crescente de
combustíveis fósseis, desde a Revolução Industrial. O Acordo de Paris e as Contribuições
Nacionalmente Determinadas (NDCs) representam os principais compromissos
internacionais para enfrentar essa crise climática. O objetivo geral da dissertação é
analisar cenários de transição energética em níveis global, regional e nacional,
identificando riscos e oportunidades para uma redução acelerada das emissões de GEE,
por meio de modelagem integrada de sistemas. Além disso, são propostas recomendações
ao aprimoramento desses modelos e ao planejamento energético voltado à mitigação das
mudanças climáticas. Utilizou-se como método, revisão de literatura e análise
internacional comparada, com base nos seguintes modelos dinâmicos (Calculadoras
2050): SINAPSE (Brasil), IESS (Índia), GAIN Energy Calculator (Estados Unidos),
EUCalc (Europa) e Global Calculator (mundial). Foram simulados cenários energéticos
que integram diferentes trajetórias de descarbonização e tecnologias energéticas, levando;se em conta fatores socioeconômicos e políticos. Os resultados revelam que, embora os
países apresentem esforços ambiciosos em suas NDCs, esses ainda são insuficientes para
atingir as metas globais do Acordo de Paris. Ao analisar as NDCs à luz dos modelos
utilizados, demonstra-se que, sem políticas mais ambiciosas, a concentração de GEE
continuará a aumentar, colocando em risco os limites de aquecimento global
estabelecidos pelo IPCC. Os modelos também permitem identificar os setores mais
críticos para uma mitigação mais profunda das respectivas matrizes energéticas. A União
Europeia tem avançado em direção a metas mais ambiciosas, enquanto países como o
Brasil e a Índia enfrentam desafios socioeconômicos que dificultam o cumprimento de
suas metas climáticas. Os Estados Unidos ainda apresentam elevadas emissões per capita
de GEE, provenientes de combustíveis fósseis. Globalmente, nota-se um descompasso
entre os discursos políticos de mitigação e as simulações realizadas. Conclui-se que a
governança climática eficaz e a cooperação internacional são essenciais para promover
uma transição energética justa e eficaz. Para acelerar a descarbonização em escala global,
é necessário aprimorar as políticas de mitigação, fortalecer os mecanismos de
financiamento e alinhar as ações globais com os potenciais identificados, por meio da
modelagem integrada de sistemas energéticos.This dissertation addresses the global energy transition and its impacts on reducing
greenhouse gas (GHG) emissions by 2050, based on the application of system dynamics
models, such as the 2050 Calculators. The energy transition is essential for mitigating
climate change and is directly linked to the historical evolution of the energy mix,
characterized by a growing dependence on fossil fuels since the Industrial Revolution.
The Paris Agreement and the Nationally Determined Contributions (NDCs) represent the
main international commitments to tackle this climate crisis. The general objective of this
dissertation is to analyze energy transition scenarios at the global, regional and national
levels, identifying risks and opportunities for an accelerated reduction in GHG emissions
through integrated systems modeling. It also proposes recommendations for improving
these models and for energy planning aimed at mitigating climate change. The method
used was a literature review and international comparative analysis, based on the
following dynamic models (Calculadoras 2050): SINAPSE (Brazil), IESS (India), GAIN
Energy Calculator (United States), EUCalc (Europe) and Global Calculator (worldwide).
Energy scenarios were simulated that integrate different decarbonization trajectories and
energy technologies, considering socio-economic and political factors. The results show
that although countries are making ambitious efforts in their NDCs, these are still
insufficient to achieve the global goals of the Paris Agreement. Analysing the NDCs in
the light of the models used shows that, without more ambitious policies, the
concentration of GHGs will continue to increase, putting the global warming limits set
by the IPCC at risk. The models also make it possible to identify the most critical sectors
for deeper mitigation of the respective energy mixes. The European Union has made
progress towards more ambitious targets, while countries such as Brazil and India face
socio-economic challenges that make it difficult to meet their climate targets. The USA
still presents a high per capita GHG emission, based on fossil fuels. Globally, there is a
mismatch between the political discourse on carbon mitigation and the simulations. It is
concluded that effective climate governance and international cooperation are essential
to promote a just and effective energy transition. To accelerate decarbonization on a
global scale, it is necessary to improve mitigation policies, strengthen financing
mechanisms and align global actions with identified potentials through integrated energy
system modelling.Centro de Desenvolvimento Sustentável (CDS)Programa de Pós-Graduação em Desenvolvimento Sustentáve
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn 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.
