Linking bioaccessibility and carotenoids to antioxidant activity in diatoms
Publication . Rocha, Helena R.; Coelho, Marta; Coelho, Natacha; Morais, Rui M. S. C.; Pintado, Manuela; Gomes, Ana M.
Diatoms are photosynthetic microalgae with a siliceous cell wall and remarkable adaptability, making them a sustainable and renewable resource for high-value bioactive compounds (1,2). Their rapid growth, efficient carbon fixation, and minimal land and freshwater requirements (1,2) position them as attractive candidates for the development of eco-friendly products in the nutraceutical, pharmaceutical, and cosmetic industries. Among their most relevant metabolites are carotenoids and phenolic compounds, which exhibit strong antioxidant properties (3,4,5). This study explores the carotenoid profile of Chaetoceros calcitrans, Nannofrustulum shiloi, and Cylindrotheca fusiformis, and evaluates their antioxidant capacity using ABTS and DPPH assays. Furthermore, the natural bioaccessibility of carotenoids was assessed using the INFOGEST in vitro digestion model, highlighting the relevance of these compounds under physiological conditions and their potential for sustainable functional applications.
Revisiting normativity for a post-cognitivist view of linguistic feeling
Publication . Batisti, Filippo; Vidal, Marcos G.; Silva, Augusto Soares da
This article reconsiders the role of affectivity in defining normativity in a situated sense. Traditional approaches have often construed language solely as a rule-governed system and cognition as a disembodied, mechanistic process. By contrast, we advance a view of language as a contextual and dynamical activity and situate cognition within affective life. Central to this reframing is the notion of linguistic feeling, understood as the affective attunement through which speakers experience and navigate norms. Rather than conceiving norms as only pertaining to convention and public criteria, we defend their function as conditions for rational experience: norms become intelligible through felt sensibilities of rightness, appropriateness, and variation. This approach overcomes internalist accounts that isolate linguistic intuitions from social and embodied contexts, showing instead how linguistic feeling is an affective manifestation of the same conceptual capacities that render us responsive to reasons. By integrating the affective and linguistic sciences, the philosophy of the space of reasons, and post-cognitivism, the paper offers a reconceptualization of normativity as rooted in sensibility. The conclusion highlights implications for linguistics, philosophy, and cognitive science, urging a shift from formalist and conventionalist models toward approaches that acknowledge the constitutive role of affect in language and rationality.
Overarching values: the pivotal tole of organizational values in navigating uncertainty
Publication . Fioravante, Rosa; Vaccaro, Antonino
This chapter introduces the construct of overarching value in organizations, a subset of core values that act as universal guiding principles, providing coherence, legitimacy, and ethical direction during times of uncertainty. These values are non-negotiable, enduring over time, yet performative, enabling organizations to navigate and overcome challenging periods by anchoring their actions to these foundational principles. Overarching values align with an organization’s rationale, mission, and cohesion, fostering a shared sense of purpose and adherence among its members. The chapter critically examines debates surrounding organizational moral values, particularly their connection to humanistic values, and the role of values work practices with special attention devoted to hybrid organizations, where values often emerge and evolve dynamically through practice. Drawing on the case of Addiopizzo—a Sicilian grassroots movement that transformed into a hybrid organization blending activism and business—this chapter demonstrates how overarching values develop through organizational processes, shaping strategic decisions and stakeholder engagement. By analyzing the emergence and application of overarching values, the chapter enhances understanding of the relative ordering of values and their function as critical drivers in overcoming turbulence, ensuring organizational resilience, and fostering ethical coherence in complex and uncertain environments.
Sustainable development strategies for national intangible cultural heritage bases: a Strengths, Weaknesses, Opportunities, and Treats–analytical hierarchy process approach to the qingshen bamboo weaving base
Publication . Su, Lijuan; Jiang, Yu; Wang, Qin; Zhu, Lin; Zhao, Can; Xia, Enlong; Li, Ge
Bamboo weaving, as a unique form of natural resource utilization and cultural exploration, is intricately linked to the livelihoods of millions worldwide. Qingshen bamboo weaving, recognized as national intangible cultural heritage in China, is the sole bamboo weaving–themed base among the latest batch of 99 national productive protection demonstration bases. This study employs a hybrid SWOT–AHP framework to empirically analyze the sustainable development pathway of the Qingshen Bamboo Weaving Base, identifying 18 key factors and calculating their relative importance through hierarchical judgment matrices. The findings reveal three primary conclusions. First, the base exhibits a predominant Strength-Opportunity (SO) strategic orientation: internal strengths (S' = 1.0012) and external opportunities (O' = 0.9530) substantially outweigh weaknesses (W' = -0.4859) and threats (T' = -0.5112), with strategic centroid P.(0.1288, 0.1105) situated in the first quadrant ((oid P(0.1288, 0.1105)) favorable window for growth-oriented strategy. Second, critical success factors exhibit significant divergence: national policy support (O1) and strategic educational partnerships (O3) emerge as paramount external drivers, while local employment enhancement and rural revitalization (S3) constitute the most significant internal strength; conversely, inadequate product design capabilities (W4) and intensified market competition (T2) represent pressing constraints, revealing a systemic deficiency in translating cultural heritage into market competitiveness. Third, sustainable development necessitates a multidimensional integrated approach—a strategic transition from a resource-dependent model toward a design-driven, brand-oriented industrial ecosystem that synergizes policy support, design innovation, digital empowerment, and community engagement. This study provides valuable insights for preserving and sustainably developing intangible cultural heritage, offering a replicable analytical framework for similar cultural heritage bases worldwide.
Boas práticas na administração de injeções intravítreas: uma revisão
Publication . Duarte, Cátia Marranita; Mesquita, Isabel; Cabral, Diogo
Este estudo teve como objetivo identificar e analisar as evidências científicas mais recentes sobre as boas práticas na administração de injeções intravítreas, com particular enfoque no contexto (consultório versus bloco operatório), na administração bilateral no mesmo dia e na estratégia de prevenção de complicações. Foi realizada uma revisão da literatura nas bases de dados MEDLINE® Complete, Scopus, Web of Science e Google Scholar, entre 2015 e 2025, com recurso a três estratégias de pesquisa distintas. Foram incluídos estudos que abordassem diretrizes e protocolos, contexto de administração e bilateralidade. A seleção e a análise dos dados foram realizadas com o apoio dos softwares Rayyan e NVivo. Nas pesquisas realizadas, 14 artigos cumpriram critérios de inclusão. Os resultados sugerem que, quando seguidas as práticas asséticas recomendadas, uso de máscara/restrição de conversa, desinfeção com iodopovidona 5% no local da punção por 30 segundos e uso de luvas, a administração em consultório e a bilateralidade são seguras. A padronização de protocolos mostrou-se essencial para a prevenção de complicações.
