Usability and Digital Accessibility for Older Adults: A Comparative Study between Moodle and Coursera
This study investigates the usability and accessibility of online learning platforms used by older adults through a comparative analysis of Moodle and Coursera. Eleven participants from the Open University for Senior Citizens (UNATI) performed structured tasks and answered questionnaires based on Nielsen’s heuristics and WCAG 2.0 guidelines, complemented by direct observation. Rather than merely comparing the platforms, this work validates a practical method for evaluating usability and accessibility, with a focus on older adults. The results indicate that, although both platforms received positive evaluations, Coursera presented significant barriers, such as navigation difficulties and inconsistent localization, whereas Moodle was perceived as more accessible and intuitive. The findings provide insights to support the development of more inclusive educational environments and the adoption of replicable assessment methodologies in diverse digital-learning contexts
Tonsillar Squamous Cell Carcinoma in a Dog: Therapeutic Effects of Carboplatin Alone and Adjuvant Piroxicam
Background: Primary tonsillar neoplasia in dogs is rare, and among these tumors, tonsillar squamous cell carcinoma (SCC) is of particular concern because of its aggressive biological behavior, high metastatic rate, and generally poor prognosis. Reported treatment strategies for this include surgery, chemotherapy, radiation therapy, and non-steroidal anti-inflammatory drugs (NSAIDs). However, the optimal therapeutic approach remains undefined, and data regarding the efficacy of systemic chemotherapy as a single modality are limited. This report describes the clinical course and outcome of a dog with advanced tonsillar SCC managed with carboplatin in combination with adjuvant piroxicam.
Case: A 14-year-old castrated male Mongrel dog was evaluated for anorexia, lethargy, and bilateral cervical masses. Physical examination and ultrasonography identified marked enlargement of the bilateral medial retropharyngeal and right submandibular lymph nodes (LNs), as well as a hypoechoic nodule in the spleen. Fine needle aspiration of both the lymph nodes and the splenic lesion revealed malignant epithelial cells. Computed tomography further demonstrated a right tonsillar mass consistent with a primary tumor, supporting a diagnosis of tonsillar SCC with concurrent lymph node and splenic metastases. The patient underwent 7 cycles of carboplatin chemotherapy (179.4-207 mg/m2, intravenous, every 3 weeks) administered concurrently with oral piroxicam (0.3 mg/kg, once, daily). Following the initial cycle, the dog exhibited rapid improvement in clinical signs, including resolution of anorexia, lethargy, and weight loss. Serial physical examination and imaging demonstrated a partial response, characterized by substantial reduction in the cumulative size of metastatic lymph nodes and complete resolution of splenic metastasis although the primary tonsillar lesion remained stable in size. After the 7th carboplatin cycle, the dog developed severe neutropenia accompanied by gastrointestinal signs, prompting discontinuation of chemotherapy at the owner’s request. Palliative management with piroxicam alone was continued, but progressive lymphadenopathy and worsening clinical symptoms ensued. The patient was transitioned to hospice care and died at home 53 days after cessation of chemotherapy, surviving 208 days from the time of diagnosis.
Discussion: This case highlights several important clinical considerations in the management of canine tonsillar SCC. Although regional lymph node involvement is common, the occurrence of splenic metastasis is rare, underscoring the importance of comprehensive diagnostic staging in patients with suspected primary tonsillar tumors. While multiple treatment modalities are available, including surgery and radiation therapy, no single strategy has been shown to consistently improve long-term outcomes, particularly in cases with advanced local invasion or metastasis where local therapies are of limited benefit. In this patient, the combination of carboplatin and piroxicam achieved meaningful clinical improvement, prolonged survival, and control of metastatic lesions in the absence of surgery or radiotherapy. These findings suggest that carboplatin, when administered alongside NSAID therapy, may provide therapeutic benefit in selected cases of advanced canine tonsillar SCC. Further studies are warranted to establish the efficacy, safety, and optimal role of chemotherapy and adjunctive agents in the management of this aggressive neoplasm.

Resenha do livro “Uma teoria do poder global”
In the book "Teoria do Poder Global" (Theory of Global Power), José Luís Fiori revisits his published work, integrating his knowledge as a sociologist, economist and political scientist to unveil a celebrated interpretation of the transformations of power in international relations. A thorough analytical review of Fiori's work (2024) was conducted, with the central objective of presenting the redefinitions of global power and shifting the conjunctural interpretation of the search for balance to an assessment that there is a logic, inherent in international power relations, of permanent conflict and management of uncertainties, both in wars and in market dynamics. The review under scrutiny here highlights the author's rejection of economicist or evolutionist interpretations of capitalism, emphasising political decisions and structural hierarchies as key factors. By examining the historical trajectory of United States hegemony and the limits of its military interventions, the work highlights the contradictory nature of the unipolar order and the emergence of new powers, especially China and Russia. The conclusion drawn therein asserts that Fiori's theory of global power synthesises a substantial bibliography, thereby facilitating the articulation of a foundational theoretical proposition for interpreting the relationships between power, historical time, and development in the interstate capitalist system.No livro “Teoria do Poder Global”, José Luís Fiori revisita sua obra acadêmica, escrita e oral, articulando seu conhecimento como sociólogo, economista e cientista político para sistematizar sua interpretação das transformações do poder nas relações internacionais. Realizamos uma resenha crítica da obra de Fiori (2024), cujo objetivo central é apresentar as redefinições do poder global, deslocando a interpretação conjuntural de busca por equilíbrios para a avaliação de que há uma lógica, inerente às relações internacionais de poder, de conflito permanente e gestão das incertezas, tanto nas guerras quanto na dinâmica de mercado. A resenha destaca como o autor rejeita interpretações economicistas ou evolucionistas do capitalismo, enfatizando decisões políticas e hierarquias estruturais. Ao reconstruir a trajetória hegemônica estadunidense e examinar os limites de suas intervenções militares, a obra evidencia o caráter contraditório da ordem unipolar e a emergência de potências emergentes, sobretudo China e Rússia. Conclui-se que a teoria do poder global de Fiori reúne uma vasta bibliografia que permite articular uma proposta teórica fundamental para interpretar as relações entre poder, tempo histórico e desenvolvimento no sistema capitalista interestatal

PADRÕES DE TRANSFORMAÇÃO URBANA E DE USO E COBERTURA DA TERRA NO LITORAL NORTE: O CASO DE OSÓRIO, TRAMANDAÍ E IMBÉ
The article investigates the patterns of urban transformation and land use and cover in the North Coast of Rio Grande do Sul (Litoral Norte do Rio Grande do Sul), focusing on the municipalities of Osório, Tramandaí, and Imbé. Located in the North Coast Urban Agglomeration (Aglomeração Urbana do Litoral Norte - AULINOR), these municipalities illustrate different dynamics of population growth, urban expansion, and land use and cover between 1985 and 2023. The North Coast region of Rio Grande do Sul stands out for having the highest population growth in the state, registering an increase of 25.8% between 2010 and 2022. Using data from IBGE and MapBiomas, the analysis reveals an intense process of urbanization driven by tourist attraction and permanent migration. The total urbanized area of AULINOR expanded by 60% during this period (increasing from 112 km2 in 1985 to 180 km2 in 2023), resulting in densification, sprawl, and conurbation. Osório stands out as a regional center with sprawling urban growth, while Tramandaí is a consolidated tourist center with dense and continuous urbanization. Imbé, a seasonal tourist center, presented the most accelerated population growth, multiplying its population by 3.6 times between 1991 and 2022, with occupation advancing over sensitive ecosystems, such as dunes and restingas (coastal scrub/dune vegetation). The study reinforces the need for integrated territorial and environmental management policies, with regionalized solutions, especially in conurbated contexts. Spatial modeling and the use of open data prove to be strategic tools to support sustainable urban planning, strengthening governance and public action regarding the impacts of coastal urbanization.El artículo investiga los patrones de transformación urbana y de uso y cobertura del suelo en el Litoral Norte de Rio Grande do Sul, centrándose en los municipios de Osório, Tramandaí e Imbé.

Going with the Flow:: tracing the Theatre Laboratory in the Brazilian Journal on Presence Studies
This article proposes a dialogical reflection on the legacy of the theatre laboratory, drawing on the experiences of Jerzy Grotowski, Eugenio Barba’s Odin Teatret, and Lume Teatro. Based on special issues of the Revista Brasileira de Estudos da Presença (particularly the editions dedicated to Grotowski, Odin Teatret, and LUME Teatro and Laboratories in Flux), we discuss how these practices emphasise encounters with the self, with others, and with cultural otherness. We also reflect on the contemporary relevance of these approaches in light of current urgencies and the challenge of sustaining such processes in the face of the immediacy imposed by neoliberal logics
Ethnic-Racial Relations in the Brazilian Journal on Presence Studies:: advances, erasures, and silencings
This text presents an analysis on the theme of ethnic-racial relations and some of its crossings, such as racism, identity, exclusion, Black culture and arts, based on the texts published by the Brazilian Journal on Presence Studies over its 15 years of publication. The discussion aimed to highlight how the journal has addressed this task in connection with contemporary debates, theorization, confrontations, and struggles on the topic. The problematization was developed from the concepts of identity and racism through the thought of Sueli Carneiro, Grada Kilomba, Achille Mbembe, and Frantz Fanon. It is inferred that academic productions that address ethnic-racial relations can play a crucial role in both the reproduction and the combat against racism
