Desigualdades digitais entre adolescentes: uma comparação entre Equador e Grécia
Get PDFThe objective of this study is to compare access to and usage of Information and Communication Technologies (ICT) among adolescents aged 12 to 14 in Ecuador and Greece, identifying inequalities driven by technological infrastructure, educational policies, and socioeconomic context. This research employed a cross-sectional descriptive design using data from Ecuador\u27s National Survey of Employment, Unemployment, and Underemployment (ENEMDU) and surveys conducted in three schools in Greece. Statistical analysis was performed using GNU PSPP software. Key findings reveal that Greek adolescents have greater access to devices such as computers and mobile phones, while Ecuadorian adolescents show intensive use of social media and mobile internet. Differences in internet access locations and device usage highlight significant disparities in infrastructure and digital practices. This study is useful for designing public policies aimed at reducing digital inequalities and promoting equitable use of ICT in education. Its novelty lies in providing a comparative analysis between countries with contrasting contexts, contributing to the understanding of how national factors influence digital inclusion.El objetivo de este estudio es comparar el acceso y uso de Tecnologías de la Información y Comunicación (TIC) entre adolescentes de 12 a 14 años en Ecuador y Grecia, identificando las desigualdades generadas por infraestructura tecnológica, políticas educativas y contexto socioeconómico.

Acesso e uso das tic entre estudantes do ensino médio no Equador e na Grécia: uma análise comparativa
Get PDFThis study examines access to and use of Information and Communication Technologies (ICT) among adolescents aged 15 to 17 enrolled in high school in Ecuador and Greece, with the aim of identifying differences and similarities linked to their educational and social contexts. The research adopted a comparative and descriptive approach, based on two main sources of information. In Ecuador, secondary data from the National Institute of Statistics and Censuses (INEC) were used, while in Greece a survey specifically designed for this study was applied in two high schools on the island of Rhodes. The findings reveal significant contrasts: in Greece, there is greater availability of computers, tablets, and laptops, whereas in Ecuador mobile phones are the main means of connection, with intensive use of the internet and social networks. Differences are also observed in the spaces of access: in Ecuador, the home predominates, while in Greece the places of connection are more diverse. The study highlights the influence of structural factors on adolescents’ digital practices and provides relevant insights for guiding educational policies that promote a more equitable integration of ICTEste estudio examina el acceso y uso de Tecnologías de la Información y Comunicación (TIC) en adolescentes de 15 a 17 años que cursan el bachillerato en Ecuador y Grecia, con el propósito de identificar diferencias y similitudes asociadas a sus contextos educativos y sociales.

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
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
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
