Comunicação em saúde : teorias sobre persuasão
(2023-12-21) Nogueira, Adinan; Pereira, Letícia Magalhães; Damásio, Manuel José; Escola de Comunicação, Arquitetura, Artes e Tecnologias da Informação
A saúde tem tido grande atenção dos governos e os investimentos em comunicação para a promoção de saúde com usos adequados de mensagens são cada vez mais necessários. Há a necessidade de investimentos para a prevenção e a diminuição dos valores investidos ao final da vida dos pacientes quando acontecem os maiores gastos devido à falta de prevenção. Porém a comunicação nesse setor é específica e requer cuidados, ainda mais em um cenário digital. Para a transmissão eficaz de mensagens relacionadas à promoção de saúde, com o objetivo de que o receptor da mensagem tome uma atitude em relação à própria saúde, é preciso que a mensagem seja persuasiva e tenha certos cuidados. Assim foi feita uma revisão bibliográfica e análise das teorias de comunicação e saúde e das pesquisas sobre persuasão a partir dos anos 60, bem como a abordagem de aspetos digitais e teorias da comunicação.
The Impact of Fermentation on the Antioxidant Activity of Food Products

From ancient times to the present day, fermentation has been utilized not only for food preservation but also for enhancing the nutritional and functional properties of foods. This process is influenced by numerous factors, including the type of microorganisms used, substrate composition, pH, time, and temperature, all of which can significantly alter the characteristics of the final product. Depending on the parameters, fermentation enhances the bioactive content of the products and imparts the necessary properties, such as antioxidant characteristics, for the products to be considered functional. The enhancement of these properties, particularly antioxidant activity, enriches foods with bioactive compounds and functional attributes, contributing to improved health benefits. Through a review of recent research, this study elucidates how different fermentation processes can enhance the bioavailability and efficacy of antioxidants, thereby improving the nutritional and functional qualities of foods. This study investigated the multifaceted effects of fermentation on antioxidant properties by exploring various types and conditions of fermentation. It highlights specific examples from dairy products and other food categories as well as the valorization of food waste and byproducts. The findings underscore the potential of fermentation as a sustainable method to produce health-promoting foods with elevated antioxidant activities, offering new perspectives for food science and technology.
An international study on psychological coping during COVID-19 : towards a meaning-centered coping style

Background/Objective: This study examined the role of different psychological coping mechanisms in mental and physical health during the initial phases of the COVID-19 crisis with an emphasis on meaning-centered coping. Method: A total of 11,227 people from 30 countries across all continents participated in the study and completed measures of psychological distress (depression, stress, and anxiety), loneliness, well-being, and physical health, together with measures of problem-focused and emotion-focused coping, and a measure called the Meaning-centered Coping Scale (MCCS) that was developed in the present study. Validation analyses of the MCCS were performed in all countries, and data were assessed by multilevel modeling (MLM). Results: The MCCS showed a robust one-factor structure in 30 countries with good test-retest, concurrent and divergent validity results. MLM analyses showed mixed results regarding emotion and problem-focused coping strategies. However, the MCCS was the strongest positive predictor of physical and mental health among all coping strategies, independently of demographic characteristics and country-level variables. Conclusions: The findings suggest that the MCCS is a valid measure to assess meaning-centered coping. The results also call for policies promoting effective coping to mitigate collective suffering during the pandemic.
Top-down Design of a CS Curriculum for a Computer Games BA
(25th ACM Conference on Innovation and Technology in Computer Science Education, ITiCSE 2020, 2020-06-15) Fachada, Nuno; Códices, Nélio; Escola de Comunicação, Arquitetura, Artes e Tecnologias da Informação; HEI-LAB (FCT) - Digital Laboratories for Environments and Human Interactions
Computer games are complex products incorporating software, design and art. Consequently, their development is a multidisciplinary effort, requiring professionals from several fields, who should nonetheless be knowledgeable across disciplines. Due to the variety of skills required, and in order to train these professionals, computer game development (GD) degrees have been appearing in North America and Europe since the late 1990s. Following this trend, several GD degrees have emerged in Portugal. Given the lack of specialized academic staff, not uncommon in younger scientific areas, some of these degrees "borrowed" computer science (CS) programs and faculty within the same institution, leading in some cases to a disconnect between CS theory and practice and the requirements of GD classes. In this paper, we discuss our experience in adapting the CS curriculum of a three-year computer games BA in accordance with GD requirements. We used a top-down approach, where the game engine used for GD informs the choice of CS topics and programming languages lectured in the CS curriculum. The discussion is centered around the choices taken and the theoretical and empirical rationale behind our decisions. Preliminary empirical results indicate a substantial increase in GD project quality and a clear improvement in the students' technical skills, as well as in their experimentation and adaptation capabilities.
Programming the logic of space : a new approach to space syntax
(Edições Universitárias Lusófonas, 2023-09) Fernandes, Pedro Afonso; Costa, Carlos Smaniotto; Aragão, Nagayamma; Costa, Carlos Smaniotto; Aragão, Nagayamma; CeIED (FCT) - Centro de Estudos Interdisciplinares em Educação e Desenvolvimento; Escola de Comunicação, Arquitetura, Artes e Tecnologias da Informação
Space syntax is a set of theories and techniques for analysing urban settlements and buildings. It is a relevant approach for spatial studies concerned with the scientific understanding of and intervention in public open spaces. It requires a previous convex/line/segment map of the area in question designed with the aid of CAD or GIS. Such preparatory task may be laborious and more difficult for social researchers than for architects or urban planners. A new approach to syntactic analyses is proposed here; it requires only setting the connections between axial lines or convex spaces in a computer program. We performed a settlement (alpha) analysis of the Areeiro neighbourhood in Lisbon by computing connectivity, control, depth, integration, ringiness and other syntactic measures, using Prolog predicates. Prolog is a logic programming language used in Artificial Intelligence and a powerful tool to describe the patterns of urban systems as socially knowable due to its declarative nature. In fact, a Prolog program represents a certain amount of knowledge, in this case, of an urban settlement such Areeiro, which is used to answer queries about the social and economic consequences of the spatial design. This approach revealed the intelligibility but also the weaknesses of Areeiro, a remarkable milestone for Portuguese urbanism from the mid-20th century.
