The economic study of politics: Insights and reflections
Félix, Laura Adão; Pereira, Francisco; Duarte, António Portugal; Bação, PedroEconomic and political phenomena coexist in society, but are often seen as divergent spheres of human action and interaction. A theoretical manifestation of this separation is the assumption that while economic agents act in their own self-interest, political agents are motivated by the public interest. Additionally, it is commonly assumed – if only implic-itly – that political agents possess all the necessary ...
On the survival of a flawed theory of capital: Mainstream economics and the Cam...
Pereira, Francisco; Moura, Mário GraçaThe Cambridge controversies on capital theory opposed heterodox economists, mainly from the University of Cambridge, UK, to mainstream economists, mostly based at the Massachusetts Institute of Technology, Cambridge, USA. The controversies started in the 1950s and occupied the pages of some of the most influential journals. Their primary outcome was the broad acknowledgement of flaws, which we retrieve, in the ...
Economics and ideology, historically and ontologically discussed [Comunicação o...
Pereira, Francisco; Moura, Mário GraçaIn this paper, we focus on the significance and semantics of ideology, starting from the history of economic thought. Our conclusion, drawing on the contributions of Marx, Schumpeter, and Lawson, is that ideology, correctly conceived, is a distinct, irreplaceable category, unavoidable in economics. This conception of ideology also explains why ontology matters to distinguish science and ideology.
Political Survival in the AI Era: a Political Economy Inquiry [Comunicação oral]
Félix, Laura; Portugal, António; Bação, Pedro; Pereira, FranciscoThe role that artificial intelligence (AI) may play on the stability of democracies and autocracies or in fostering regime transitions has attracted significant attention in recent years. Empirical evidence shows that public expenditures on AI are on the rise in autocracies and a correlation between the deployment of AI and a decrease in social unrest has been documented. [...]
The Portuguese Economy: The challenge of low growth and high debt
Araújo, Isabel; Lourenço, Diogo; Pereira, FranciscoIn the report entitled Global Trends 2030 – citizens in an interconnected and polycentric world, edited by Álvaro Vasconcelos, three mega-trends were identified for the evolution of global society until 2030: the empowerment of individuals, greater human development with rising inequality, climate change and scarcity of natural resources, and, finally, the emergence of a polycentric world with concomitant regul...
Estudantes Nacionais no Acesso ao Ensino Superior: Quem são, que escolhas fazem...
Sá, Carla; Sin, Cristina; Pereira, Francisco; Aguiar, Joyce; Tavares, OrlandaEste estudo foi desenvolvido no âmbito do projeto de investigação Estudantes nacionais e internacionais no acesso ao ensino superior, do Centro de Investigação de Políticas do Ensino Superior (CIPES). As opiniões expressas nesta publicação refletem o posicionamento dos seus autores e não vinculam necessariamente o EDULOG.
AI, docking, and molecular dynamics to track the binding of structural peptides...
Ferreira, Tiago; Pereira, Francisco; Gonçalves, Filipa; Costa, André da; Cavaco-Paulo, Artur; Castro, Tarsila GabrielThe present work shows a computational approach to assess the interactions of different nature-inspired peptides with hair keratin models. An updated keratin model was validated, and comparisons with previous models were traced, thereby highlighting the time-evolution of both the model and the in silico methods. Importantly, the computational methodology presented here allows for the study of peptide-protein in...
Influence of plasmonic thin-film-coated photobioreactors on microalgal biomass ...
Pereira, Francisco; Vicente, A. A.; Vaz, Filipe; Borges, Joel; Geada, Pedro Miguel MacedoMicroalgae emerge as an eco-friendly solution for food, feed, pharmaceutical, energy, and environmental remediation, providing a diverse range of valuable biocompounds to address the growing global demand. However, light conditions pose substantial challenges, limiting their photosynthetic efficiency and productivity. Light concentration and manipulation provided by plasmonic effects, coupled with photobioreact...
Insights on microalgae-based technologies with potential impact on global metha...
Madureira, Leandro Filipe Feiteira; Soares, Ana Sofia Maciel; Duarte, Maria Salomé Lira; Pereira, Francisco; Francisco, DiogoThe European Unions Methane Action Plan outlined policies and targets supporting the Global Methane Pledge to cut CH4 emissions by 30% by 2030, yet urgent implementation is needed to treat medium and diluted CH4 streams. Microalgae-based technologies offer a groundbreaking solution, merging CH4 mitigation with biomass valorization to drive sustainable industrial practices. This review examines three key applica...
Peptide-keratin interactions for enhanced hair properties
Carvalho, José; Rodrigues, Ana Rita O.; Ferreira, Tiago; Gomes, Vânia; Pereira, Francisco; Martins, Cátia D. F.; Martins, MadalenaSummary Fusion peptides inspired by natural elastomeric proteins are fused to a keratin peptide (KP) and tested on damaged hair. Here, we report thermal and mechanical tests conducted on treated damaged hair in conjunction with the peptides physicochemical properties, resulting in a statistical multiparametric analysis. Among the parameters, the Youngs modulus and the keratin helix denaturation temperature show...
