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
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
Além do plantio de árvores : mobilização de redes de produção de restauração do Cerrado
Full text linkDissertação (mestrado) — Universidade de Brasília, Instituto de Ciências Biológicas, Programa de Pós-Graduação em Ecologia, 2023.Um diverso e robusto suprimento de produtos e serviços é essencial para restaurar milhões de
hectares de ecossistemas abertos degradados a fim de cumprir compromissos globais de
restauração. No entanto, as práticas de restauração são notavelmente limitadas pela inclusão
inadequada de biodiversidade nativa e restrição de participação social nas decisões. Neste
estudo, nós analisamos como os desenvolvimentos institucionais, operações de mercado e
sistemas de suprimento configuram a rede de produção de restauração do Cerrado. Nossas
análises revelam assimetrias de poder entre os múltiplos atores, levando a uma distribuição
desigual de investimentos, demandas de mercado e recursos tecnológicos ao longo das escalas.
As políticas e regulamentações vigentes continuam a priorizar princípios centrados em
florestas, desconsiderando os requisitos únicos de ecossistemas savânicos. Em meio a esses
desafios, nós identificamos o cumprimento de legislações ambientais nacionais como o
mercado de restauração mais influente no Cerrado, embora com demandas regionais que
permanecem instáveis e voláteis. Entretanto, comunidades locais, que fornecem produtos e
serviços, desencadeiam inovações baseadas no território para co-criar a organização coletiva e
as técnicas adequadas ao local, avançando no desenvolvimento de práticas para restauração de
savanas. Nossa pesquisa ressalta a importância de promover procedimentos participativos de
modo a reconfigurar como as instituições e mercados priorizam engajamentos locais para
incorporar plenamente considerações acerca da biodiversidade e garantir a distribuição
equitativa dos benefícios da restauração.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)A diverse and robust supply of products and services is essential for restoring millions of
hectares of degraded open-canopy ecosystems to meet global restoration pledges. Yet
restoration practices are notably constrained by the inadequate inclusion of native biodiversity
and limited social participation in decisions. Here, we analyze how institutional developments,
market operations, and supply systems configure the Brazilian Savanna restoration production
network. Our analyses reveal power asymmetries between multiple stakeholders, leading to an
uneven distribution of investments, market demands, and technological resources across scales.
Prevailing policies and regulations continue to prioritize forest-centric principles, disregarding
the unique requirements of savanna ecosystems. Amidst these challenges, we identify
compliance as the most influential restoration market in the Brazilian Savanna, albeit with
regional demands that remain unstable and volatile. Nevertheless, community suppliers spark
place-based innovations to co-create collective organization and situated techniques, advancing
savanna restoration practices. Our research underscores the significance of promoting
participatory procedures to reshape how institutions and markets prioritize local engagements
to fully incorporate biodiversity considerations and ensure equitable sharing of restoration
benefits.Instituto de Ciências Biológicas (IB)Programa de Pós-Graduação em Ecologi

Seeding tropical ecosystems: Governance of landscape restoration in the Brazilian Amazon
Full text linkLandscape restoration has evolved to recover large areas of degraded ecosystems through a globally coordinated governance system to connect economic development with local livelihood improvements. The Brazilian government set an ambitious target to restore 12 million hectares of degraded land by 2030. This thesis examines how stakeholders manage multi-scalar relations of governance and institutional systems for restoration in the Brazilian Amazon in order to explore how performance and outcomes are socially and geographically embedded in hybrid power dynamics. I demonstrate these processes across the diverse roles of state, market actors, communities, and individuals, through the application of global production networks, feminist political ecology, and forest landscape restoration frameworks to advance the environmental governance literature. As an empirical representation, the research focuses on case studies in the southeastern Amazon. The governance of the restoration network in Brazil is formed by a myriad of forces connecting disparate stakeholders, involving regulations, global funding, actor-specific decision-making, community participation, and technological developments. Formal institutions commonly take a highly technical approach, and excessive bureaucratization has decentralized responsibility, but not authority, from the governments. However, the dispersed nature of restoration networks across multiple stakeholders illustrates alternative levels of engagement, beyond the state’s power. Innovative seed supply and direct seeding have initiated approaches based on local knowledge in the Amazon. Diverse community groups are adapting local institutions for restoration with significant livelihood improvements, including indigenous and women's participation in seed collection. Community-based models are feasible for matching the plant material sources required to achieve Brazil's restoration pledge with considerable and positive socioeconomic outcomes
