- How can design thinking improve food sustainability in the Minho region (eno)gastronomy? A multi-actor perspectivePublication . Oliveira, Rafael; Campos, Susana; Rodrigues, Ana Sofia; Vaz-Velho, Manuela; Correia, Ricardo JorgePurpose | This study has the following main goals: i) to define barriers and present specific solutions associated with the food ecosystem, common to the various actors in the territory; ii) to explore the present and future of Minho's (eno)gastronomy and iii) provide innovative responses that meet contemporary consumer demands in terms of health and sustainability. Methodology/Approach | Trough Design Thinking, we pursued a collaborative approach that melds gastronomic traditions with health and sustainability imperatives, ensuring holistic solutions that valorize Minho’s heritage. The process involved iterative workshops, engaging diverse stakeholders to analyze the historical and current state of Minho’s (eno) gastronomy, focusing on the transition to healthier and more sustainable practices. This multi-actor approach enabled integrated solutions, enhancing the food system while considering climate change impacts and modern health trends. Expected Results | The topics addressed by the region's players associated with the agri-food sector and the solutions proposed highlighted the intrinsic relationship between local production and sustainability, emphasising that the proximity between producer and consumer translates not only into a smaller carbon footprint, but also into the socioeconomic and cultural enhancement of the region. These results will enable policymakers to apply a multi-actor approach, taking into account the needs of the various stakeholders in the region and implementing concerted actions that jointly respond to the challenges and needs we have identified.
- How can Design Thinking improve food sustainability in the Minho Region? A multi-actor perspectivePublication . Campos, Susana; Oliveira, Rafael; Correia, Ricardo Jorge; Oliveira, Ana Teresa; Rodrigues, Ana Sofia; Velho, Manuela VazUsing the Design Thinking methodology and the multi-actor approach, the aim was to find an innovative and collaborative perspective that reconciles gastronomic traditions with health and sus-tainability criteria. To this end, two workshops were held, bringing together 12 participants from the agri-food ecosystem in the Minho region. We concluded that the topics discussed and the solutions proposed highlighted the intrinsic relationship between local production and sustainability, empha-sizing that the proximity between producer and consumer translates not only into a lower carbon footprint but also into the socio-economic and cultural enhancement of the region. The richness of Minho products, from their flavors, textures, and stories, deserves to be celebrated but also protected and adapted to the new challenges of today's society.This study has a very original and multidisci-plinary approach. Integrating different actors, specialties, and perspectives has promoted a rich ex-change of knowledge and experience, materialized in convergent ideas. To improve the future of enogastronomy, the design thinking approach is used for the first time in literature to promote inte-grated solutions in the Minho food system.
- Partial occlusion in facial expression recognition: a systematic literature reviewPublication . Rodrigues, Ana Sofia; Lopes, Júlio Castro; Vieira, João; Lopes, Rui PedroThis study presents a Systematic Literature Review (SLR) examining Facial Expression Recognition (FER) under partial occlusion conditions. Analyzing a diverse array of studies, it identifies prevalent methodologies and challenges within the field. The review reveals a significant use of Gabor filters for feature extraction and classification, highlighting their efficiency in FER research. Additionally, black patches emerge as the primary method for simulating occlusions, which reflects the scarcity of datasets containing such occlusions. The complexity of FER under occlusion conditions is highlighted by the inconclusive findings on the relative importance of facial regions like the mouth and eyes in expression recognition. The results point to the need for more research to comprehend the complex role of different facial regions in conveying emotions. Furthermore, the review emphasizes the importance of developing larger and more diverse datasets, that encompass a broader range of facial expressions and occlusion types, to advance the development and evaluation of FER systems in real-world scenarios.
- Willingness to pay for ecolabel in food products: mapping publications over the past twenty yearsPublication . Campos, Susana; Borges, Eduardo; Correia, Ricardo Jorge; Ferreira-Oliveira, Ana Teresa; Rodrigues, Ana Sofia; Teixeira, Mário SérgioEcolabels can be a tool to promote and support more sustainable products, providing information that allows consumers to select products with better environmental performance. Ecolabels can help create ecological awareness around sustainable consumption, promote environmentally friendly attitudes, and contribute to responsible consumption habits. This article reviews the lit-erature on willingness to pay for ecolabels on food products and identifies four main knowledge gaps: (1) the effect of variables that signal quality, safety, or health benefits on willingness to pay for ecolabels; (2) the impact of ecolabels on the environment from a regulatory point of view; (3) the lack of a measurement instrument that serves general application with various stakeholders; and (4) how ecolabels contribute to green innovation. Our re-sults contribute to the literature and define and implement more efficient and effective public policies that facilitate communication between producers and consumers. Based on 31 articles selected and analyzed in a systematic literature review, we found that the variables related to consumers' willing-ness to pay vary according to the level of education, income, age, marital sta-tus, family size, attitude, previous experience and knowledge, among others. We conclude that consumers are willing to pay more for environmentally sustainable products and that the ecolabel is particularly important in their choice.
