A growing body of literature suggests that the platformization of the public sphere is eroding the public debate, thus potentially leading to the fragmentation of the public sphere. While there exists mounting evidences supporting this perspective there also exists a substantial body of literature that suggests otherwise. Within this realm of mixed evidence, studies on climate change visibility play a prominent role, presenting findings that both weaken and reinforce the fragmentation hypothesis. To investigate this matter in a context conducive for a fragmented public sphere, we collected a longitudinal (2014-2022) and cross-platform (Instagram, Facebook and Twitter) dataset (n=794.281) and correlated it with a secondary database on the press coverage of climate change in Brazil (n=3.490). Our analysis reveals a robust positive correlation between these datasets, indicating that the Brazilian public sphere retains the capacity to interconnect various arenas of visibility. We argue that this finding is particularly significant, given that it emanates from a case characterized by circumstances favoring a high degree of public sphere fragmentation. Consequently, our discovery lends support to a less pessimistic assessment of the influence of platformization on political communication within the deliberative system. debate otherwise evidence role hypothesis 20142022 2014 2022 (2014-2022 crossplatform cross platform Instagram, Instagram (Instagram Twitter n=794.281 n794281 n 794 281 (n=794.281 n=3.490. n3490 n=3.490 . 3 490 (n=3.490) datasets significant Consequently system 2014202 201 202 (2014-202 n=794.28 n79428 79 28 (n=794.28 n349 n=3.49 49 (n=3.490 201420 20 (2014-20 n=794.2 n7942 7 2 (n=794.2 n34 n=3.4 4 (n=3.49 20142 (2014-2 n=794. n794 (n=794. n3 n=3.

ABSTRACT Purpose: We reported, as a referral center in prostate cancer, our perspectives and experience performing Telesurgery using robotic surgery and 5G network. Material and methods: We described and illustrated the Telesurgery applications and outcomes to treat a patient with prostate cancer located 1300 kilometers away from the surgeon (Beijing-Harbin) in China. We used the Edge Medical Robot (MP1000) in November 2023 in a 71-year-old patient with Gleason 6 (ISUP 1) in 8 cores from 13, PSA of 14 ng/dL, and clinical stage cT2a. MRI described a PIRADS 5 nodule on the left peripheral zone at the base, and 20gr prostate. We described details about the connection between centers, perioperative outcomes, and our perspectives as a referral center in prostate cancer. Results: We had no delays, or problems with network connection between the centers. The procedure was performed in 60 minutes, with no intra- or postoperative complications. Estimated blood loss was 100 mL. The patient was ambulating soon after anesthesia recovery. Final pathology described a Gleason 6 (ISUP 1) involving the left base and left seminal vesicle, negative surgical margins, and no lymph node involvement (pT3bN0). The patient was continent soon after catheter removal (7 days). Conclusion: As technological progress introduced novel robotic platforms and high-speed networks, the concept of Telesurgery became a tangible reality while 5G technology solved latency and transmission concerns. However, with these advancements, ethical considerations and regulatory frameworks should underline the importance of transparency and patient safety with responsible innovation in the field.

Abstract This article endeavours to examine how Brazilian television has responded to technological trends in the context of media convergence within the realm of Brazilian television, with a specific focus on the streaming platform of Globo Group, the largest media conglomerate in Latin America, known as Globoplay. The central argument of this paper revolves around the various forms of engagement employed by the organisation as it seeks to adapt to the changing landscape of media. Using the case study method (Yin, 2015), this research correlates the theoretical framework with three central points aimed at discussing engagement in the era of media convergence as a foundation for television’s relationships with its advertisers, the creation of audiovisual products and projects, and, most importantly, its relationship with the contemporary audience. The analysis underscores the use of techniques such as artificial intelligence and machine learning, which aid the platform in reshaping its strategies and decision-making processes. In light of the findings and subsequent discussion, it can be inferred that the primary goal of these initiatives is to foster engagement among both its audience and advertisers.

Resumo Este artigo visa examinar como a televisão brasileira tem respondido às tendências tecnológicas no contexto da convergência mediática, com foco específico na plataforma de streaming do Grupo Globo, o maior conglomerado de média da América Latina, conhecida como Globoplay. O argumento central deste artigo gira em torno das várias formas de engajamento empregues pela organização enquanto procura adaptar-se ao cenário de constante mudança dos média. Utilizando o método de estudo de caso (Yin, 2015), esta pesquisa correlaciona o quadro teórico com três pontos centrais destinados a discutir as noções de engajamento na era da convergência dos média como base para as relações da televisão com os seus anunciantes, a criação de produtos e projetos audiovisuais e, sobretudo, a sua relação com a audiência. A análise destaca o uso de técnicas como inteligência artificial e aprendizagem automática, que ajudam a plataforma a remodelar as suas estratégias e processos de tomada de decisão. À luz dos resultados e discussão subsequentes, pode-se inferir que o objetivo principal dessas iniciativas consiste em adaptar-se ao contexto hipertelevisivo e ampliar o modo como o Grupo Globo se relaciona tanto com o seu público como com os seus anunciantes.

Abstract In view of the economic, political, and technological changes in the world of work within the urban territory, nowadays we are facing new informalities that increase the precariousness of work relationships and conditions in a global level. This essay aims to reflect critically on new subjectivations and on psychosocial risks related to the uberization of work, analyzing their impacts on territorial dynamics. We highlight platform companies that offer taxi and delivery services, and we provide a panorama that shifts from the international to the national scenario. Uberized workers face unique episodes of violence committed by platform companies and urban violence, which intensify psychosocial risks and harm workers' dignity, health, and quality of life. The practices of platform companies, as well as their management and contradictions, reveal a deprivation of the right to the city and the capture of workers' subjectivity. economic political territory level dynamics services scenario dignity health life contradictions subjectivity

ABSTRACT In this study, a mixture of estradiol benzoate, progesterone, and testosterone propionate was injected into Diannan small-ear sows to induce estrus. The 16S rRNA technology was used to comparatively analyze the differences in fecal microbial composition and diversity between induced and spontaneous estrus in Diannan small-ear sows. The most abundant phylum in the sows in estrus were Firmicutes, Bacteroidetes, Actinobacteria, and Proteobacteria. There was a significant negative correlation between Firmicutes and Bacteroide and a significant positive correlation between Bacteroides and Bifidobacterium. The relative abundance of Stenotrophomonas, Neisseria, Anaerofustis, and Terrisporobacter in the sows during induced estrus was significantly higher than that during spontaneous estrus. Taken together, induced estrus affects the relative abundance of specific microbes in the feces of Diannan small-ear sows, but it does not affect the overall composition and diversity. These results provide fundamental knowledge about the gut microbiota of sows with induced estrus. study benzoate progesterone smallear small ear S Bacteroidetes Actinobacteria Proteobacteria Bifidobacterium Stenotrophomonas Neisseria Anaerofustis together

Abstract Objective: To revise the impact of telehealth on the quality of life, reduction in pulmonary exacerbations, number of days using antibiotics, adherence to treatment, pulmonary function, emergency visits, hospitalizations, and the nutritional status of individuals with asthma and cystic fibrosis. Data source: Four databases were used, MEDLINE, LILACS, Web of Science and Cochrane, as well as manual searches in English, Portuguese and Spanish. Randomized clinical trials, published between January 2010 and December 2020, with participants aged 0 to 20 years, were included. Data synthesis: Seventy-one records were identified after the removal of duplicates; however, twelve trials were eligible for synthesis. Included trials utilized: mobile phone applications (n=5), web platforms (n= 4), mobile telemedicine unit (n=1), software with an electronic record (n=1), remote spirometer (n=1), and active video games platform (n=1). Three trials used two tools, including telephone calls. Among the different types of interventions, improvement in adherence, quality of life, and physiologic variables were observed for mobile application interventions and game platforms compared to usual care. Visits to the emergency department, unscheduled medical appointments, and hospitalizations were not reduced. There was considerable heterogeneity among studies. Conclusions: The findings suggest that better control of symptoms, quality of life, and adherence to treatment can be attributed to the technological interventions used. Nevertheless, further research is needed to compare telehealth with face-to-face care and to indicate the most effective tools in the routine care of children with chronic lung diseases.

Abstract Technological advancement has had a significant impact on written production, especially in Additional Languages (ALs). Although technology has brought new opportunities for AL teaching, it also poses challenges, including concerns about the complexity of writing and the authenticity of students’ work. One such tool is ChatGPT, an artificial intelligence (AI) platform that has been the subject of debate since its popularization in 2022. This study analyses a corpus consisting of six tasks produced by ChatGPT in five languages (German, Spanish, French, Italian, and Portuguese), considering the proficiency levels proposed by the Common European Framework of Reference for Languages (CEFR), totalling 2991 texts and 706,401 words. The data were generated by students in a computer lab at a British university from 100 different profiles on the ChatGPT platform, following the researchers’ instructions. Data analysis employs Systemic Functional Linguistics (SFL) and the concept of lexical density ( Halliday, 1985, 1987, 1993; Halliday; Matthiessen, 2014) to investigate the complexity of the produced texts, as lexical complexity is related to proficiency in writing, where more advanced texts proportionally use more “content words” (nouns, verbs, adjectives, and some adverbs of manner). The results reveal that ChatGPT does not adhere to task instructions regarding the requested word count, thereby impacting the calculation of lexical density, nor does it produce texts that show significant differences in lexical density among additional languages and proficiency levels. production ALs.

Resumo O avanço tecnológico tem tido um grande impacto na produção escrita, especialmente em Línguas Adicionais (LAs). Embora a tecnologia tenha trazido novas oportunidades para o ensino de LAs, ela também apresenta desafios, incluindo preocupações sobre a complexidade da escrita e a autenticidade dos trabalhos dos alunos. Uma dessas ferramentas é o ChatGPT, plataforma de inteligência artificial (IA) que tem sido objeto de debates desde sua popularização em 2022. Este estudo analisa um corpus composto por seis tarefas produzidas pelo ChatGPT em cinco idiomas (alemão, espanhol, francês, italiano e português), considerando os níveis de proficiência propostos pelo Quadro Comum Europeu de Referência para Línguas (CEFR), que totalizou 2991 textos e 706,401 palavras. Os dados foram gerados por alunos em um laboratório de informática em uma universidade britânica a partir de 100 diferentes perfis na plataforma do ChatGPT, seguindo instruções dos pesquisadores. A análise dos dados utiliza a linguística sistêmico-funcional (LSF) e o conceito de densidade lexical ( Halliday, 1985, 1987, 1993; Halliday; Matthiessen, 2014) para investigar a complexidade dos textos produzidos, dado que a complexidade lexical está relacionada à proficiência na escrita, na qual textos mais avançados usam proporcionalmente mais “palavras de conteúdo” (nomes, verbos, adjetivos e alguns advérbios de modo). Os resultados revelam que o ChatGPT não segue as instruções das tarefas quanto ao número de palavras solicitadas, impactando, assim, no cálculo da densidade lexical, nem produz textos que mostram diferenças significativas da densidade lexical entre as línguas adicionais e níveis de proficiência.

ABSTRACT Objective: comprehend the challenges and solutions faced by a non-technological and non-profit organization, acting within a coopetitive environment, in the construction of a multisided platform business model. Method: utilizing a qualitative case study approach, we investigated FEBRAFAR, a multisided platform of drugstore retailers, manufacturers, and service providers. Data collection and analysis was based on the following categories: (a) the methods through which the platform generates value for its diverse customer segments, (b) the intricate contours of its value configuration endeavor, and (c) its strategies for value appropriation to ensure both sustainability and growth. Results: the challenges in establishing an efficiently functioning multisided platform business model included: getting resources; member's attraction; and resistance to adopting best management practices. The solutions contained the development of value creation techniques for its varied customer segments by reducing transactional friction with customers and suppliers, a comprehensive value configuration process, and value appropriation that promote sustainability and growth to these drugstore chains. Conclusion: the paper shows how FEBRAFAR got the solution of value creation and appropriation of the platform business model by orchestrating the interactions of competing entities within the stakeholder ecosystem that engage in collaboration. By establishing clear rules and interaction protocols, a multisided platform can facilitate coordination among competing entities, thereby enabling collaborative value co-creation for all involved stakeholders. This finding contributes to the broader understanding of strategic management in multisided platforms, particularly in non-technology contexts.

PURPOSE OF THE STUDY: By including advertisements in VLEs, both academically and commercially, HEIs can potentially reduce the significant financial costs associated with the implementation, utilisation and maintenance required for their chosen VLEs, without decreasing the value of the service provided, while simultaneously providing a source of long-term sustainable revenue for HEIs. Consequently, the primary objective of this study was to determine whether gender differences exist among students' attitudes towards the use of a VLE with the presence of advertisements at a South African university of technology DESIGN/METHODOLOGY/APPROACH: The sampling frame for this study comprised a public registered South African university of technology. A non-probability convenience sample of 379 students was used. A hand-delivered, self-administered questionnaire was distributed to full-time students during class time at the chosen HEI FINDINGS: There was a statistically significant difference found between male and female students at the chosen South African university of technology in terms of the perceived usefulness of VLEs. There is no statistically significant difference between male and female students' self-efficacy, technology experience, satisfaction, perceived ease of use, perceived usefulness, attitudes towards the use of a vLe without the presence of advertisements and attitudes towards the use of a VLE with the presence of advertisements RECOMMENDATIONS/VALUE: Not only do VLEs, being web-based, provide a means for HEIs to generate long-term revenue, but they have the capacity to become open digital platforms for marketers to take advantage of. With the use of these VLEs, marketers may find it easier to reach their target audiences in a more focused approach when placing advertisements on this platform, while HEIs can use the income generated to cover the cost of any technological advancements that may be required, without having to increase student fees MANAGERIAL IMPLICATIONS: The management of HEIs need to decide if they would like to consider this means of revenue generation and see if it will indeed be as beneficial as what the theory suggests. In order to avoid any potential financial risks associated with the implementation of advertisements on VLEs, HEIs can engage in trial run projects with a willing organisation to analyse the viability of this proposed initiative JEL CLASSIFICATION: M31, M37

Resumo O artigo é fruto de uma investigação que objetivou compreender narrativas de 15 estudantes dos Anos Finais do Ensino Fundamental sobre seus territórios vividos no bairro Santa Helena, no município de Governador Valadares, Minas Gerais, quando eles/elas mobilizam práticas de numeramento nessas narrativas. Assume as contribuições teóricas de estudos sobre práticas de numeramento, reconhecendo que elas se inserem nas tessituras das práticas de letramento, em diálogo com Henri Lefebvre sobre a produção do espaço e sua tríade analítica – espaço concebido, vivido e percebido. O material empírico foi produzido durante uma oficina na qual os/as estudantes foram convidados/as a traçar, em um mapa, o itinerário que realizam de casa até a escola. Para isso, eles/as utilizaram os recursos disponibilizados pela plataforma on-line Google My Maps. Durante a oficina, identificou-se o evento O mapa do Adriano, selecionado para análise e discussão, em que o estudante, mediado pela tela de um computador, apropria-se da linguagem tecnológica própria da plataforma My Maps, acolhendo e tensionando o espaço concebido pelos criadores da plataforma com os espaços vividos/percebidos por ele no bairro. Desse modo, o estudante produz significados próprios para a produção e leitura de mapas na tela de um computador, tornando-se protagonista das práticas vividas e narradas por ele. Destaca-se que o uso da plataforma My Maps se mostra uma ferramenta potente para a produção de cartografias, para estudos que operam com os conceitos de território e práticas de numeramento e, de modo geral, para o campo da Educação Matemática. 1 Helena Valadares Gerais eleselas eles letramento percebido osas convidadosas convidados traçar escola isso elesas online on line identificouse identificou Adriano discussão computador apropriase apropria vividospercebidos percebidos tornandose tornando Destacase Destaca cartografias geral Matemática

Abstract This article results from a study aimed to understand the mobilization of numeracy practices in the narratives of fifteen middle school students about their lived spaces in the Santa Helena neighborhood, in the city of Governador Valadares, Minas Gerais, Brazil. It assumes the theoretical contributions of studies on numeracy practices, recognizing that they are inserted in the fabric of literacy practices, dialoguing with Henri Lefebvre on the production of space and his analytical triad – conceived, lived, and perceived space. The empirical material was produced during a workshop in which students drew the way they take from home to school on a map, using the resources provided by the online platform Google My Maps. During the workshop, we identified the event ‘Adriano's map’. We selected it for analysis and discussion. Mediated by the computer screen, the student appropriates the technological language, typical of the My Maps platform, welcoming and tensioning the space conceived by the platform creators with the spaces lived/perceived by him in the neighborhood. Thus, the student produces his own meanings for producing and reading maps on a computer screen, becoming the protagonist of the practices he lived and narrated. My maps platform stands out as a powerful tool to produce cartography in studies that operate with the concepts of territory and numeracy practices and for the field of Mathematics Education in general. neighborhood Valadares Gerais Brazil map ‘Adrianos Adrianos ‘Adriano s Adriano map. . map’ discussion screen language livedperceived Thus narrated general

Abstract Housing rental relationships have changed due to technological innovations and critical situations that have exacerbated their conflictual nature and their importance to social wellbeing. This article analyzes the conflictive nature of these relationships, the possible growth of the problem as a result of the pandemic caused by COVID-19, as well as the challenges to introduce legal reforms in Mexico aimed at regulating the housing rental market. A review of situations of tension or confrontation between tenants and owners, as well as national and state legislation, was carried out. These reviews made it possible to identify common problems and market regulation options aimed at reducing transaction costs and expanding the population’s freedom of choice of housing and the right to the city. Reforms are explored to develop local government capacities to monitor and inspect the quality of housing and to operate a digital platform for the conclusion of lease contracts that are recognized in courts.

Resumen Las relaciones de arrendamiento de vivienda han cambiado debido a innovaciones tecnológicas y situaciones críticas que han exacerbado su naturaleza conflictiva y su importancia para el bienestar social. Este artículo analiza el carácter conflictivo de dichas relaciones y el posible crecimiento de este problema a raíz de la pandemia provocada por el COVID-19, así como los retos para introducir en México reformas legales dirigidas a regular el mercado de renta de viviendas. Se realizó una revisión de situaciones de tensión o confrontación entre inquilinos y propietarios, así como de legislación nacional y estatal. Estas revisiones permitieron identificar problemas comunes y opciones de regulación del mercado dirigidas a reducir los costos de transacción y a expandir las libertades de elección de vivienda de la población y el derecho a la ciudad. Se exploran reformas para desarrollar capacidades del gobierno local para monitorear e inspeccionar la calidad de la vivienda y para operar una plataforma digital para la celebración de contratos de arrendamiento que sean reconocidos en juzgados.
