Discovering Time-Varying Public Interest for COVID-19 Case Prediction in South Korea Using Search Engine Queries: Infodemiology Study
Authors: Ahn Seong-Ho , Yim Kwangil , Won Hyun-Sik , Kim Kang-Min , Jeong Dong-Hwa 
Published: October 2024

Background
The number of confirmed COVID-19 cases is a crucial indicator of policies and lifestyles. Previous studies have attempted to forecast cases using machine learning techniques that use a previous number of case counts and search engine queries predetermined by experts. However, they have limitations in reflecting temporal variations in queries associated with pandemic dynamics.

Objective
This study aims to propose a novel framework to extract keywords highly associated with COVID-19, considering their temporal occurrence. We aim to extract relevant keywords based on pandemic variations using query expansion. Additionally, we examine time-delayed web-based search behavior related to public interest in COVID-19 and adjust for better prediction performance.

Methods
To capture temporal semantics regarding COVID-19, word embedding models were trained on a news corpus, and the top 100 words related to “Corona” were extracted over 4-month windows. Time-lagged cross-correlation was applied to select optimal time lags correlated to confirmed cases from the expanded queries. Subsequently, ElasticNet regression models were trained after reducing the feature dimensions using principal component analysis of the time-lagged features to predict future daily case counts.

Results
Our approach successfully extracted relevant keywords depending on the pandemic phase, encompassing keywords directly related to COVID-19, such as its symptoms, and its societal impact. Specifically, during the first outbreak, keywords directly linked to COVID-19 and past infectious disease outbreaks similar to those of COVID-19 exhibited a high positive correlation. In the second phase of the pandemic, as community infections emerged, keywords related to the government’s pandemic control policies were frequently observed with a high positive correlation. In the third phase of the pandemic, during the delta variant outbreak, keywords such as “economic crisis” and “anxiety” appeared, reflecting public fatigue. Consequently, prediction models trained by the extracted queries over 4-month windows outperformed previous methods for most predictions 1-14 days ahead. Notably, our approach showed significantly higher Pearson correlation coefficients than models based solely on the number of past cases for predictions 9-11 days ahead (P=.02, P<.01, and P<.01), in contrast to heuristic- and symptom-based query sets.

Conclusions
This study proposes a novel COVID-19 case-prediction model that automatically extracts relevant queries over time using word embedding. The model outperformed previous methods that relied on static symptom-based or heuristic queries, even without prior expert knowledge. The results demonstrate the capability of our approach to track temporal shifts in public interest regarding changes in the pandemic.
Representações femininas na mídia: entre rupturas e continuidades em canções pop
Authors: Rebouças Marcela Aianne , Braga Nayara Nicoly , Tavares Lúcia Helena Medeiros da Cunha 
Published: October 2024

Partindo da premissa de que as mulheres, com o avanço das pautas femininas e a conquista de direitos sociais e políticos, adentraram a esfera pública, criando e falando sobre si mesmas nos mais variados suportes, este artigo ambiciona investigar as produções discursivas femininas na contemporaneidade. Com o intuito de observar a mulher descrevendo a si própria, objetivamos analisar os modos de subjetivação dos sujeitos femininos no discurso midiático por meio de canções do gênero pop internacional. Para tanto, nosso corpus é constituído por duas canções: Ain’t Your Mama, de Jennifer Lopez e positions, de Ariana Grande, que são analisadas à luz dos Estudos Discursivos Foucaultianos e dos estudos feministas, pautados por autoras como bell hooks (2019; 2020), Michelle Perrot (2020), dentre outras, por meio do método arqueogenealógico. Os resultados indicam a predominância de duas representações femininas que circulam na atualidade: uma, alinhada à resistência dos sujeitos femininos aos padrões e, outra, em conformidade aos moldes patriarcais, moralistas e conservadores.
Ethé discursivos de Getulio Vargas nas marchinhas Gê-Gê (1931) e O Retrato do Velho (1951)
Authors: Da Silva Davi Costa , Abreu-Aoki Raquel 
Published: October 2024

O objetivo deste trabalho é analisar discursivamente as marchinhas Gê-Gê (Seu Getulio), de Lamartine Babo, e O Retrato do Velho, de Haroldo Lobo e Marino Pinto, identificando e demonstrando os ethé, imagens projetadas para Getulio Vargas (GV) nessas canções. Compostas em 1931 e 1951, respectivamente, as marchinhas se inserem em contextos políticos distintos, os quais ensejaram construções de ethé para Getulio Vargas adequados à necessidade histórico-discursiva de cada momento. Do ponto de vista teórico, este trabalho dialoga, sobretudo, com a Teoria Semiolinguística do Discurso e o ethos político de Patrick Charaudeau (1994; 2004; 2014; 2018). Nesses trabalhos, o autor situa o ethos como uma estratégia de persuasão que condiciona a adesão do público à figura e aos ideais de um dado político, o que coloca o ethos em posição de centralidade no discurso político. A análise discursiva do corpus apontou que foram traçados os ethé de moderno, patriota e revolucionário na marchinha Gê-Gê (Seu Getulio), e os ethé de chefe, popular, carismático e experiente na marchinha O Retrato do Velho. Embora produzidos em uma instância cidadã, esses discursos reiteram ideias normalmente advindas de uma instância política, uma vez que incorporam o discurso oficial da época e delineiam ethé positivos e elogiosos para o presidente Getulio Vargas.
A mulher negra heroína: análise do cordel “Maria Felipa”
Authors: Queiroz Eduardo Prachedes 
Published: October 2024

Neste artigo, examinamos a constituição temática e figurativa de mulheres negras no texto Maria Felipa, um dos cordéis que compõem o livro de Jarid Arraes denominado Heroínas negras brasileiras em 15 cordéis (2020). Com a análise de tal texto, temos o propósito de compreender e evidenciar tanto o processo como o resultado da construção da imagem dessas mulheres negras, comparando os resultados encontrados a partir do exame com estereótipos comuns na representação das mulheres em parte das produções culturais brasileiras. Para a análise, servimo-nos do ferramental da Semiótica Discursiva para explorar questões relacionadas à narratividade e à discursividade no texto de Arraes, utilizando conceitos como os de isotopia, sujeito e objeto (Greimas; Courtés, 2016). Percebem-se, no cordel analisado, figuras como as guerreiras, as lutadoras e o fogo ateado a embarcações que, junto de temas como o da batalha e o da liderança, ressaltam a heroicidade das mulheres negras. Também são notadas estratégias narrativas que destacam sua agência e protagonismo, como a ocupação do papel actancial de sujeito e a sanção positiva sobre Maria Felipa.
Da banalidade à repressão: uma análise estilística de “Cotidiano”, de Chico Buarque
Authors: Mendes Beatriz Farias 
Published: October 2024

Este trabalho busca oferecer uma análise estilístico-discursiva da letra da canção “Cotidiano”, de Chico Buarque, observando os efeitos de sentido causados pela repetição. Propõe-se analisar a letra da canção, presente no álbum Construção (1971), segundo a Estilística do Discurso (HENRIQUES, 2011) e com o auxílio de formulações teóricas e de trabalhos da Semiótica Discursiva (FIORIN, 1996), a fim de considerar não apenas os recursos estilísticos textuais e a imbricação das camadas discursivas na construção de sentido, mas também o contexto de produção e o meio no qual a canção está inserida. A partir de Henriques (2011), analisa-se a letra da canção ao longo deste artigo observando as diversas camadas da linguagem verbal orquestradas no gênero em questão, depreendendo a expressividade de cada camada e sua relação com o conteúdo à medida em que se torna relevante para a argumentação. Por meio deste percurso, demonstra-se como a repetição de diversos recursos expressivos, a coesão semântica responsável por formar diferentes isotopias e o contexto de lançamento da obra são responsáveis por construir a ambiguidade do texto por meio da repetição. Conclui-se então que a letra da canção transita entre a banalidade do dia a dia de um casal e a repressão da Ditadura Militar por meio da atualização de sentido do próprio texto, construindo assim, também, uma crítica social ao regime.
Da iconicidade em "Asa Branca"
Authors: Fonseca Alef James 
Published: October 2024

Este artigo apresenta uma análise semiótica da canção “Asa Branca”, gravada por Luiz Gonzaga em 1975 pela RCA Camden, com o propósito de investigar os procedimentos enunciativos do cantor pernambucano que produzem na canção um efeito particular de iconicidade apontado pelo professor e músico baiano Paulo Costa Lima. Esse efeito já foi descrito por Greimas e Courtés como ilusão referencial (2013), e por Jacques Fontanille como um processo de estabilização dos formantes figurativos da linguagem (2005). Em “Asa Branca”, os procedimentos de iconização parecem alcançar também um caráter sinestésico em razão do sincretismo de melodia e letra, conforme apontamentos de Jean-Marie Floch (1986). Para dar conta dessa análise, que demanda um exame integral do sincretismo cancional, adotamos o método hipotético-dedutivo da Semiótica Discursiva de Aljirdas Julien Greimas (2014), além de sua vertente tensiva conduzida por Claude Zilberberg (2006, 2011), e da Semiótica da Canção de Luiz Tatit (1997, 2012, 2014). Também recorremos às formulações de Fontanille e Zilberberg sobre o devir (2001), e aos estudos de Hans-Joachim Koellreutter sobre harmonia funcional (2018) para descrever o modo como a estrutura harmônica contribui para a construção de efeitos iconizantes e sinestésicos na canção.

Public integrity, transparency and accountability have been identified as part of the founding principles of the public sector which should be enacted in legislation and applied consistently in practice. Effective implementation of the accountability principle shall underpin integrity of public service and its legal, professional and transparent operation.The purpose of the paper is to analyze conceptual issues of public officials' accounta­bility, focusing on disciplinary responsibility and application in practice. The paper also presents the results of the research conducted in 30 local self government units in the Re­public of Serbia. The results point out the (non)efficient implementation of legal and ethi­cal rules and values concerning disciplinary procedures, sanctions, performance appraisal system in the context of possible improvements and capacity building. In order to enhance public integrity, appropriate legislative and institutional frameworks must be in place to enable public-sector organizations to take responsibility for effectively managing the integ­rity of their activities, as well as that of the public officials who carry out those activities.
La Disponibilidad de cuarzo apto para la talla en las Sierras Pampeanas Australes
Authors: Caminoa José María , Cattáneo Roxana , Carignano Claudio 
Published: October 2024

This paper presents the results of the study on the availability and use of quartz suitable for flintknapping in the Ongamira Valley (Córdoba, Argentina. At the archaeological sites studied—which correspond to late Holocene hunter-gatherer groups (ca. 1900-3600 BP)—more than 90% of the lithic assemblages were quartz. Researchers articulated different analysis techniques (remote sensing, prospecting, XRF, XRD and petrographic analyses) to understand the origin and local availability of this raw material. The results reveal the location and abundance of the primary quartz sources, estimate the material quality, and help us comprehend the variability between sources. Based on the data, the paper proposes a methodological model for discussing quartz use in the mountainous regions of Central Argentina and its integration into interpretations of human mobility circuits.

Adjectives ‘otdalyonnyy’ [distant], ‘priblizitelnyy’ [approximate], and ‘neulovimyy’ [elusive] as Means of Expressing Semantics of Implicit Similarity
Authors: Kalinina L. V. 
Published: October 2024

This article is dedicated to linguistic means that denote implicit similarity between one object and another. The author aims to identify common patterns in constructing contexts that describe situations of implicit similarity. The study focuses on the specific usage of the adjectives ‘otdalyonnyy’ [distant], ‘priblizitelnyy’ [approximate], and ‘neulovimyy’ [elusive], along with their derived adverbs, as tools for expressing implicit similarity. The research employs definitional, componential, distributional, and contextual analysis methods, utilizing data from linguistic dictionaries and the Russian National Corpus. The analysis of corpus data reveals that situations of implicit similarity can be characterized by four criteria: “semantic class,” “basis for comparison,” “degree of similarity,” and “presence of explanations.” It is demonstrated that the contextual synonyms ‘otdalyonnyy (-o)’ [distant (-ly)], ‘priblizitelnyy (-o)’ [approximate (-ly)], and ‘neulovimyy (-o)’ [elusive (-ly)] exhibit several distinctions in their functioning across various criteria: frequency of use, collocational compatibility, semantic class of the compared objects, basis for comparison, and degree of expressed implicit similarity. In most cases, implicit similarity between objects is not thoroughly motivated but is presented as a ready result of perception, comparison, and interpretation carried out by the speaker.

Māori leadership and early childhood educational leadership in Aotearoa: A critical literature review
Authors: Dayman Tracy , Warren Alison , Tuhakaraina Sandra , Robinson Lesley , Haruru Emma 
Published: October 2024

Abstract
Five early childhood teacher educators in Aotearoa New Zealand explored a range of literature to respond to the question: What does literature tell us about Māori leadership and how are our findings relevant to leadership in early childhood education (ECE) in Aotearoa? The process of finding and reviewing literature sources about Māori leadership led us to think critically about how Māori values, concepts, and customs have been diminished or sustained in fields such as education and business. ECE in Aotearoa is shaped by the bicultural curriculum Te Whāriki and underpinned by obligations to Te Tiriti o Waitangi. Although education and leadership structures and processes in Aotearoa are overwhelmingly produced within Westernised perspectives, ECE curriculum and practice foregrounds Māori ways of knowing, being, and doing. Through the literature review process, we shared insights and critical discussions that enriched our perceptions of leadership by and for Māori, and of relevance to ECE leadership through shared values. The literature reviewed provided examples from education and business settings where Māori leadership grounded in values of whanaungatanga/reciprocal relationality originating in Māori traditional beliefs and societal structures has been sustained, remembered, and reclaimed through processes of navigating and negotiating present-day colonised contexts. Literature also provided examples of official programmes and policies that seek to acknowledge and enhance Māori leadership in education.
Sintered Clays: Application in the Removal of Arsenic from Water by Filter Beds

Objectives: The main objective of the research was to build a ceramic filter bed, using red clay and diatomite, for the removal of arsenic in aqueous media and to propose an environmentally friendly and low-cost technique for rural communities in Peru that consume water contaminated with arsenic.

Theoretical framework: Arsenic is a common contaminant in the drinking water of many rural communities in Peru, exceeding the limits allowed by the WHO. Prolonged exposure to arsenic can cause serious health problems. The use of low-cost non-metallic materials, such as thermally activated clay and diatomite, is proposed for its adsorption.

Method: A filter bed composed of 5 cm layers of red clay and diatomite with particle sizes of 0.81, 0.31 and 0.20 mm was used. Both materials were thermally activated at 900°C and placed on a stainless steel support. The arsenic removal process was evaluated by passing a synthetic solution with 13.99 ppm of arsenic through the bed. Material characterization analyses were performed before and after the adsorption process, using techniques such as ICP-OES, SEM, FTIR, among others.

Results and discussion: The filter bed composed of diatomite (83.31% SiO2) and red clay (8.23% Fe2O3) achieved an arsenic removal of up to 99.99%, highlighting the efficiency of particles with a size of 0.20 mm. This shows that the combination of these materials can be highly effective in removing arsenic in water, which is promising for its implementation in rural areas.

Research implications: This research has important implications for water treatment in rural communities facing arsenic contamination problems. The technique developed is low-cost and uses abundant resources, which facilitates its application at the local level and promotes sustainable solutions for access to safe drinking water.
Originality/Value: The research provides a novel approach through the use of red clay and diatomite, accessible resources, thermally activated for the removal of arsenic in water. In addition, the high removal effectiveness achieved provides a potentially scalable and replicable solution in other rural communities with similar problems.
Problems and prospects of scientific and technological cooperation between Russia and India in modern conditions: international legal dimension
Authors: Shugurov Mark Vladimirovich , Pechatnova Yuliya Vadimovna 
Published: October 2024

The subject of the study is the intensification of cooperation between Russia and India in the field of science, technology and innovation in the context of responding to anti-Russian sanctions against Russian science. The purpose of the article is to identify the initiative directions of scientific and technological cooperation between the two countries in modern conditions, which will effectively implement the provisions that form a systemic legal framework for bilateral cooperation. The article shows that Russia is the initiator of the intensification of cooperation, intending to compensate for the damage caused by the loss of institutional ties with some of the main partner states in the scientific field. The authors elaborate on the characteristics of the mechanism of legal regulation of Russian-Indian scientific and technological cooperation both from the point of view of its historical formation and through the prism of its compliance with the modern needs of intensifying bilateral cooperation. In the process of achieving the research goal and solving the tasks set, the authors used the following methods and approaches: historical and legal method, forecasting method, formal dogmatic method, systematic approach, modeling method. The authors of the article came to the conclusion that the operation of the developed international legal mechanism for regulating the ISTC of the two countries has become the basis for the successes achieved in long-term cooperation. This mechanism combines the implementation of the provisions of intergovernmental bilateral agreements (vertical level), as well as the provisions of agreements concluded between Russian and Indian institutions of the scientific and educational sphere (horizontal level). The directions of cooperation and the prospects for its regulation are set by political and legal documents of a strategic nature (declarations, statements, memoranda). All this is complemented by the use of a programmatic method that creates conditions for the implementation of relevant international legal obligations. The organizational mechanism is represented by intergovernmental structures. At the same time, currently this cooperation is not so significant in its scope, and the provisions of political and legal documents sometimes have the character of declarative intentions, which are not yet embodied in a wide range of specific scientific projects. The novelty of the article lies in understanding the prospects of the Russian-Indian ISTC through the prism of solving the problem of enhancing Russia's participation in cooperation in geographical areas not complicated by sanctions.
