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
Exploración del conocimiento matemático de los pescadores de la bahía de Puerto Montt, Chile
No full textThe potential of recognizing and using the mathematics of different cultural practices from each country has been highlighted in the Ethnomathematics Program, in order to strengthen their teaching and learning. In countries such as Chile, many inhabitants are dedicated to fishing. However, the potential of this practice to address the mathematical learning proposedin the national curriculum has not been studied. With the aim of exploring the mathematical knowledge of fishermen in the bay of Puerto Montt, Chile, and following a qualitative methodology with an ethnographic approach, semi-structured interviews were conducted with seven fishermen from this area. Data were analyzed according to a thematic analysis. The results show that fishermen have mathematical knowledge associated with most of the axes that integrate the national curriculum of mathematics in basic education in terms of the study ofmeasurement (conventional and non-conventional), localization (spatial orientation), counting, modeling (ratios between variables and conversions), and estimation (of measurements and ofquantity), among others. Lastly, some guidelines are proposed on how to link this knowledge to the national curriculum.O potencial de reconhecer e utilizar a matemática de diferentes práticas culturais de cada país é destacado no Programa Etnomatemática, a fim de fortalecer seu ensino e aprendizagem.

Visando a explorar os conhecimentos matemáticos dos pescadores da baía de PuertoMontt, Chile, e seguindo uma metodologia qualitativa com uma abordagem etnográfica, foram realizadas entrevistas semiestruturadas a sete pescadores desta área. Os dados foram analisados segundo uma análise temática. Os resultados mostram que os pescadores possuemconhecimentos matemáticos associados à maioria dos eixos que integram o currículonacional de matemática na educação básica quanto ao estudo da medição (convencional e não convencional), localização (orientação espacial), contagem, modelagem (relações entre variáveis e conversões), e estimação (de medidas e quantidade), entre outros. Finalmente,algumas diretrizes são propostas sobre como vincular este conhecimento ao currículo nacional.Desde el Programa Etnomatemática se ha destacado el potencial de reconocer y utilizar las matemáticas presentes en diversas prácticas culturales propias de cada país para fortalecer su enseñanza y aprendizaje.

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
Voice-Controlled Robotics in Early Education: Implementing and Validating Child-Directed Interactions Using a Collaborative Robot and Artificial Intelligence
No full textPublisher Copyright: © 2024 by the authors.This article introduces a voice-controlled robotic system for early education, enabling children as young as four to interact with robots using natural voice commands. Recognizing the challenges posed by programming languages and robot theory for young learners, this study leverages recent advancements in artificial intelligence, such as large language models, to make robots more intelligent and easier to use. This innovative approach fosters a natural and intuitive interaction between the child and the robot, effectively removing barriers to access and expanding the educational possibilities of robotics in the classroom. In this context, a software pipeline is proposed that translates voice commands into robot actions. Each component is tested using different deep learning models and cloud services to determine their suitability, with the best ones being selected. Finally, the chosen setup is validated through an integration test involving children aged 4 to 6 years. Preliminary results demonstrate the system’s capability to accurately recognize and execute voice commands, highlighting its potential as a valuable educational tool for early education
