- Product ideation in the age of artificial intelligence: insights on design process through shape coding social robotsPublication . Chakraborty, Shujoy; Loyens, Dirk; Aston, JeremyThis research explores the impact of generative artificial intelligence (GenAI) on ideation and concept design of social robots capable of undertaking sustained long-duration human–robot interaction. The work reported here was developed between 2021 and 2024 through classroom teaching executed in four editions of 3-day project workshops involving 36 product design master students producing 27 concept design proposals in a European Higher Education Institute (HEI). The first two workshop editions used only classical methods utilising semantic moodboarding, sketching, virtual 3D modelling, and rendering. The last two editions employed mixed methods blending classical methods with computational methods using text-to-image and sketch-to-image GenAI tools, like Midjourney, DALL-E, and Vizcom. The findings suggest that using mixed methods, which co-creates by combining organic and synthetic creativity, enhances the concepts’ numeric quantity, although the concepts’ creative quality remains questionable. The advantage of the computationally enhanced mixed methods over the traditional classical methods is the greater potential to overcome creative blockages in novice designers with weak ideation skills. Increasing the volume of concept exploration increases the serendipitous probability of arriving at successful outcomes. This research is a case study of GenAI implementation in classroom teaching, highlighting its benefits and limitations for design courses in HEIs.
- Estudos Culturais – Estudos Inter-Multi-Trans-Pan-Anti-In-DisciplinaresPublication . Sarmento, Clara; Diniz, Bruna SaadéEstudos Culturais: Estudos Inter-Multi-Trans-Pan-Anti-In-Disciplinares explora as diversas vertentes dos Estudos Culturais à luz da interdisciplinaridade, numa afirmação da constante irreverência, pertinência e vitalidade da área. Pensar e praticar os Estudos Culturais enquanto área inter-, multi, trans- e pan- disciplinar não significa trilhar um caminho vago e indefinido, numa anti-/in-disciplina aleatória, árida, alheada dos contextos que condicionam a academia contemporânea. Bem pelo contrário, os ensaios coligidos neste volume desafiam as fronteiras disciplinares que mais não fazem do que perpetuar as hierarquias do poder e reproduzir os discursos ideologicamente orientados sobre a vulnerabilidade das Ciências Sociais e Humanas. Essas fronteiras disciplinares anacrónicas contaminam a capacidade de intervenção intelectual, política e social dos Estudos Culturais. Por essa razão, a intervenção anti- e in-disciplinar dos Estudos Culturais torna-se ela própria num projeto académico orientado para a defesa de uma academia contemporânea e inclusiva, ciente das mudanças exigidas pela decolonização, pelos feminismos, por todas as identidades situadas algures no espectro inter-, multi-, trans- e pan-. Nesse sentido, os Estudos Culturais discutidos ao longo destas páginas são inter-, multi-, trans- e pan- disciplinares para se poderem anti- encerrar face aos confinamentos intelectuais e in-disciplinar face aos poderes hegemónicos, honrando o legado dos Estudos Culturais do Centre for Contemporary Cultural Studies de Birmingham e de Stuart Hall. Porque: [Cultural studies] does have some stake in the choices it makes. It does matter whether cultural studies is this or that. It can’t be just any old thing which chooses to march under a particular banner. It is a serious enterprise, or project, and that is inscribed in what is sometimes called the ‘political’ aspect of cultural studies. Not that there’s one politics already inscribed in it. But there is something at stake in cultural studies, in a way that I think, and hope, is not exactly true of many other very important intellectual and critical practices. Here one registers the tension between a refusal to close the field, to police it and, at the same time, a determination to stake out some positions within it and argue for them. Stuart Hall, “Cultural Studies and its Theoretical Legacies”, 1992. Os capítulos aqui compilados provêm de uma seleção dos trabalhos apresentados ao III Congresso da RNEC – Rede Nacional em Estudos Culturais, organizado pelo Centro de Estudos Interculturais (CEI) do Politécnico do Porto, nos dias 11 e 12 de julho de 2024, no ISCAP – Instituto Superior de Contabilidade e Administração do Porto. A Rede Nacional em Estudos Culturais representa uma comunidade de centros de investigação, instituições de ensino superior, licenciaturas, mestrados, doutoramentos e pós-graduações que tem vindo a expandir-se de forma assinalável ao longo dos últimos anos em Portugal. O seu III Congresso promoveu, uma vez mais, o reconhecimento desta comunidade construída em torno dos Estudos Culturais e potenciou diálogos articulados e densos por parte de académicos, investigadores e instituições nacionais e...
- Evaluation of the potential of annatto seed powder to reduce the formation of heterocyclic amines in charcoal-grilled and pan-fried beef pattiesPublication . Gonçalves, Thaís de Moura Neves; Braga, Anna Rafaela Cavalcante; Pinto, Edgar; Viegas, Olga; Mesquita, Leonardo M. de Souza; Ferreira, Isabel Maria Pinto Leite Viegas Oliveira; García-Jares, Carmen; De Rosso, Veridiana Vera; Domene, Semíramis Martins Álvares; Pinto, EdgarVarious strategies are being explored to reduce the formation of undesirable compounds during the thermal processing of foods. This study investigates the impact of incorporating annatto seed powder (Bixa orellana L.) into beef patties to reduce the formation of heterocyclic amines (HAs) during charcoal-grilling and pan-frying. A three-level full factorial design was used to assess the effect of both annatto seed powder concentration and cooking times on HAs formation. The results showed that HA formation increased with longer cooking times and decreased with higher concentrations of annatto seed powder. A significant reduction in HA content was observed in both charcoal-grilled and pan-fried beef patties when annatto seed powder was added, with a particularly notable 91 % reduction at the 1 % addition level. These findings demonstrate that the addition of annatto seed powder is a highly effective strategy for reducing HA formation in beef patties.
