- Coagglomeration patterns in portuguese labour-intensive industries: complementarity and specialisation dynamicsPublication . Cesário, MarisaThe aim of this paper is to analyse the patterns of industrial agglomeration in Portugal in order to understand their underlying dynamics. Industries tend to be concentrated geographically, rather than due to random causes, natural advantages or Marshallian forces. Empirically, industry pairwise coagglomeration is measured using the Ellison and Glaeser (1997) metric, with the goal of understanding the complementarity versus specialisation dynamics behind the industrial geographic concentration in Portugal. It is concluded that the most prominent industrial clusters in Portugal are as follows: textiles and clothing, footwear and transport, each one having a different agglomeration dynamic. While some sectors tend to benefit more from the interdependencies along the value chain (meaning vertical industrial relationships, related to complementary dynamics), others are more vulnerable to labour pooling (more to do with horizontal industrial relationships and specialisation dynamics), and others to both. For policymakers, for instance, it is of great use to know exactly the right triggers as the success of any programme results from the suitability of the initiatives being financially supported.
- Delays in the stroke care pathway in a low-income setting: an audit study from MozambiquePublication . Buque, Helena Agostinho; Smith, Lee; Lopes, Dino; Pizzol, Damiano; Lorenzo, Elder; Arroz, Nachan; Bacallau, Lazara; Sidat, Mohsin; Bauaze, Evangelina Namburete; Nzwalo, HipólitoBackground: The burden of stroke is on the rise in low-income countries (LICs). Organized stroke care (OSC) is crucial for improving outcomes in LICs and is the very first step to reducing delays in diagnosis and treatment. We aim to evaluate delay times (DT) in accessing OSC at the national reference hospital of Mozambique, a LIC from southern Africa. Methods: An observational study based on consecutive case series of 59 stroke patients confirmed by computed tomography (CT) scans over a period of 3 months (May–July 2023). The total DT (from stroke onset to inward hospitalization) was the main outcome. Other specific DTs were analyzed including initial symptoms to arrival and admission (DT0), arrival to CT scans (DT1), arrival of laboratory results (DT2), and arrival to inward hospitalization (DT3). Results: The mean age was 61.9 (min 30–max 90) and 45.8% were female. The median total DT was 20 h. The median time DT0 was 10.6 h (interquartile range (IQR): 16.48). The median DT1 and DT2 were 4 h (IQR: 3.5) and 5 h (IQR: 2.6), respectively. The median DT3 was 10 h (IQR: 4). None of the patients were treated under a stroke code. Conclusions: This study reveals an unacceptable prehospital and in-hospital DT. Waiting for the CT scan contributed to a large proportion of the total DT, which among other factors can be explained by the absence of a stroke code and limited imaging capacity. These findings mirror disparities in stroke care seen in other LICs, where late presentation, scarce imaging, and limited specialized protocols are common. The urgent implementation of organized prehospital and in-hospital stroke pathways is needed in Maputo to improve outcomes.

- “E-migrantes” y las redes sociales digitales en la construcción de un espacio transnacional: el caso de los peruanos en PortugalPublication . Marques, João Filipe; Calla Jesús de Sousa, YeseniaEste artículo busca comprender la influencia de las redes sociales digitales (RSD) en la vida cotidiana de los inmigrantes. Se pretende entender de qué manera estas prácticas contribuyen a la construcción de un espacio transnacional, considerando que esta expresión se refiere al mantenimiento de lazos entre los inmigrantes y su país de origen, así como a la formación de vínculos con sus compatriotas que también viven en el extranjero. El artículo recurre al concepto de “e-migrantes” para designar a aquellos que, mediante el uso de tecnologías de la información y la comunicación (TIC), permanecen conectados entre sí y con su país de origen. Como caso empírico, se estudia a los inmigrantes peruanos residentes en Portugal. La pregunta de investigación fue la siguiente: ¿de qué forma la comunidad peruana que vive en Portugal utiliza las RSD? El artículo se centra en las prácticas que emergen de la apropiación de las plataformas digitales — en particular, la construcción de “comunidades virtuales” — a través de una metodología mixta que incluye el análisis de un conjunto de entrevistas semiestructuradas, una encuesta en línea y datos estadísticos sobre el uso de las RSD.
- Pathways to progress: unveiling structural change in Africa through economic transformation, technology, talent, and tourismPublication . Pinto, Hugo; Odoi, Evans; Nogueira, Carla; Viana, Luiz Fernando CâmaraAfrican economies are undergoing significant structural transformation, transitioning from agriculture to manufacturing, services, and technology-driven industries. Driven by urbanization, technological innovation, and global trade, this shift offers opportunities for sustainable growth but faces challenges such as infrastructure gaps and institutional hurdles. This paper examines the dynamics of structural change in 54 African countries, focusing on the roles of technology, talent, and tourism. Using World Bank data, factor and cluster analyses reveal five latent components: structural conditions, public sector capacities, dynamic conditions, urbanization, and growth. The analysis categorizes countries into six clusters, from Developing Economies to African Powerhouses. The findings emphasize the critical role of technology in boosting productivity, the importance of talent development through education and workforce integration, and the potential of sustainable tourism to drive transformation. This research provides a comprehensive framework for understanding Africa’s structural transformation, offering actionable insights to address disparities and promote equitable development across the continent.
- Resident empowerment in all-inclusive context: cost–benefit perception and support for sustainable tourism development in a small island destinationPublication . Santos, Edson Redy Moreira dos; Nobre Pereira, Luis; Pinto, Patrícia; Ribeiro, Manuel AlectorThis study examines the relationships among resident empowerment, perceptions of tourism costs and benefits, and support for sustainable tourism development (SSTD) in a small island destination dominated by all-inclusive resorts. Using survey data from 341 residents in Cape Verde and employing PLS-SEM analysis, results reveal significant relationships between empowerment, benefits, and SSTD. The perception of all-inclusive resorts' positive impacts moderates the relationship between empowerment and SSTD, while the perception of all-inclusive resorts' costs does not moderate any relationships. The study contributes to understanding how all-inclusive tourism development influences resident attitudes and support for sustainability in small island contexts. The findings underscore the importance of empowering residents and managing perceptions of tourism impacts to foster SSTD. Practical implications include the need for policies that promote local empowerment, equitable benefit distribution, and mitigation of negative impacts to ensure long-term sustainability of small island destinations and beyond.
- Unraveling the potential of gasotransmitters as neurogenic and neuroprotective molecules: focus on Alzheimer's and Parkinson's diseases.Publication . Simao, Sonia; Filipa Santos, Daniela; Teixeira, Mariana; Ribeiro Agostinho, Rafaela; Rodrigues, Joana; Vitorino, Marta; Pombinho de Araújo, Inês MariaAlzheimer's disease and Parkinson's disease are the two most prevalent neurodegenerative disorders worldwide, both characterized by progressive neuronal loss. Despite distinct pathophysiological features, they share cellular dysfunctions such as abnormal protein aggregation, oxidative stress, and neuroinflammation, research into which might be beneficial for developing novel therapeutic strategies that could tackle both conditions. This review highlights the emerging role of the gasotransmitters nitric oxide, carbon monoxide and hydrogen sulfide as modulators of adult neurogenesis and neuroprotection in Alzheimer's disease and Parkinson's disease. We have gathered recent evidence demonstrating that these endogenous gases exert anti-inflammatory, antioxidant, and anti-apoptotic effects, and, critically, promote neurogenesis - suggesting a dual neuroprotective and neuroregenerative therapeutic potential. The unique physicochemical features of these gasotransmitters, including their ability to cross the blood-brain barrier and diffuse rapidly throughout the neural tissue, further support their suitability as candidates for innovative neuroregenerative treatments. While clinical translation remains challenging, harnessing the neurogenic and neuroprotective actions of these gasotransmitters may offer transformative avenues for addressing the increasing burden of Alzheimer's disease and Parkinson's disease.
