Os desafios do jornalismo online a luz das tecnologias de inteligencia artificial: The challenges of electronic journalism in light of artificial intelligence technologies
No full textThe objective of this study was to analyze the main challenges facing online journalism with the increasing integration of artificial intelligence technologies, as well as their professional, ethical, and future implications. The work seeks to understand how these technologies are transforming journalistic practices, news production models, and the relationship between journalists, audiences, and content. The methodology employed was theoretical-analytical, based on a critical review of specialized literature on artificial intelligence, digital journalism, and communication studies. Fundamental concepts, characteristics, and areas of application of artificial intelligence were analyzed, as well as its benefits and risks in the field of online journalism, drawing on previous studies and conceptual approaches. The results demonstrate that artificial intelligence offers significant benefits to online journalism, such as increased efficiency, automation of routine tasks, content personalization, and improved analysis of large volumes of data. However, significant challenges were also identified, including the spread of fake news, algorithmic bias, job losses, privacy risks, and a decline in journalistic creativity. The study concludes that artificial intelligence does not completely replace journalists but rather redefines their role, demanding new technological and ethical skills. The future of online journalism will depend on the balance between leveraging these technologies and preserving the profession\u27s core values, especially credibility, social responsibility, and journalistic ethics.El objetivo del estudio fue analizar los principales desafíos que enfrenta el periodismo electrónico ante la incorporación creciente de las tecnologías de inteligencia artificial, así como sus implicaciones profesionales, éticas y futuras. El trabajo busca comprender cómo estas tecnologías están transformando las prácticas periodísticas, los modelos de producción informativa y la relación entre periodistas, audiencias y contenidos. La metodología empleada fue de tipo teórica–analítica, basada en la revisión crítica de literatura especializada en inteligencia artificial, periodismo digital y estudios de comunicación. Se analizaron conceptos fundamentales, características y áreas de aplicación de la inteligencia artificial, así como sus beneficios y riesgos en el ámbito del periodismo electrónico, apoyándose en estudios previos y enfoques conceptuales. Los resultados evidencian que la inteligencia artificial aporta importantes beneficios al periodismo electrónico, como el aumento de la eficiencia, la automatización de tareas rutinarias, la personalización de contenidos y la mejora en el análisis de grandes volúmenes de datos. No obstante, también se identificaron desafíos relevantes, entre ellos la propagación de noticias falsas, los sesgos algorítmicos, la pérdida de empleos, los riesgos para la privacidad y la disminución de la creatividad periodística. Se concluye que la inteligencia artificial no sustituye completamente al periodista, sino que redefine su rol, exigiendo nuevas competencias tecnológicas y éticas. El futuro del periodismo electrónico dependerá del equilibrio entre el aprovechamiento de estas tecnologías y la preservación de los valores fundamentales de la profesión, especialmente la credibilidad, la responsabilidad social y la ética informativa.O objetivo deste estudo foi analisar os principais desafios enfrentados pelo jornalismo online com a crescente integração das tecnologias de inteligência artificial, bem como as suas implicações profissionais, éticas e futuras.

Comunicação política via redes sociais eletrônicas (Facebook) e seu impacto na participação eleitoral dos jovens na Argélia
Get PDFThis research paper aims to understand the political communication process via electronic social networks in general, and Facebook in particular, and its impact on electoral participation. The extensive and widespread use of social media has allowed election candidates to articulate their ideas, principles, and goals by promoting their election campaigns via Facebook. This has significantly impacted the target audience and, consequently, the level of electoral participation among youth. The importance of employing political communication to promote positive political participation is highlighted, particularly in the electoral process, which typically witnesses intense competition among candidates to win seats. Thus, candidates are able to professionally use social media tools to promote their electoral platform and reach the largest possible segment of voters.Este documento de investigación tiene como objetivo comprender el proceso de comunicación política a través de las redes sociales electrónicas en general, y Facebook en particular, y su impacto sobre la participación electoral. El uso extenso y generalizado de los medios sociales ha permitido que los candidatos electorales articulen sus ideas, principios y objetivos mediante la promoción de sus campañas electorales a través de Facebook. Esto ha afectado considerablemente al público destinatario y, en consecuencia, al nivel de participación electoral entre los jóvenes. Se destaca la importancia de emplear la comunicación política para promover una participación política positiva, en particular en el proceso electoral, que suele ser testigo de una intensa competencia entre los candidatos para obtener escaños. Por lo tanto, los candidatos son capaces de utilizar profesionalmente las herramientas de medios sociales para promover su plataforma electoral y llegar al mayor segmento posible de votantes.Este artigo de investigação tem como objetivo compreender o processo de comunicação política através das redes sociais eletrónicas em geral, e do Facebook em particular, e o seu impacto na participação eleitoral. O uso extensivo e disseminado das redes sociais permitiu aos candidatos às eleições articular as suas ideias, princípios e objetivos, promovendo as suas campanhas eleitorais através do Facebook. Isto impactou significativamente o público-alvo e, consequentemente, o nível de participação eleitoral entre os jovens. Salienta-se a importância do emprego da comunicação política para promover a participação política positiva, particularmente no processo eleitoral, que normalmente testemunha uma intensa competição entre os candidatos pela conquista de lugares. Assim, os candidatos podem utilizar profissionalmente as ferramentas das redes sociais para promover a sua plataforma eleitoral e alcançar o maior segmento possível de eleitores
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
