- Exploring biosensors’ scientific production and research patterns: a bibliometric analysisPublication . Valente, Bernardo; Pinto, Hugo; Pereira, Tiago Santos; Campos, RitaMore sustainable biosensor production is growing in importance, allowing for the development of technological solutions for several industries, such as those in the health, chemical, and food sectors. Tracking the latest advancements in biosensors’ scientific production is fundamental to determining the opportunities for the future of the biosensing field. This article aims to map scientific production in the biosensors field by running a bibliometric analysis of journal articles registered in the Web of Science database under biosensor-related vital concepts. The key concepts were selected by researchers and biosensor technology developers working on the Bio Assembler Horizon project. The findings lead to identifying the scientific and technological knowledge base on biosensing devices and tracking the main scientific organizations developing this technology throughout the COVID-19 period (2019–2023). The institutional origin of the publications characterized the global distribution of related knowledge competencies and research partnerships. These results are discussed, shedding light on the scientific, economic, political, and structural factors that contribute to the formation of a scientific knowledge-based focus on the performance and design of these sensors. Moreover, the lack of scientific ties between the three axes of organizations producing expertise in this area (China, USA, and Russia) points towards the need to find synergies through new mechanisms of co-authorship and collaboration.
- Variability in the effect of climate variables on the reproductive outputs of sea turtles that share nesting groundsPublication . Garcia, Olivia; Fuentes, Mariana; Castilho, RitaClimate change is expected to impact animals whose life history traits are reliant on environmental parameters. This is the case for sea turtles, who lay their eggs at temperate and tropical beaches and have the development of their embryos dependent on environmental conditions at their nesting grounds. Understanding how sea turtles reproduction will be impacted by climate change is crucial to guide effective management and help maintaining sea turtle populations. Studies that have explored the effects of local climate variables on sea turtles reproductive outputs have focused on individual species, with no research to date comparing effects across species that nest at the same location and under similar conditions. We address this knowledge gap by comparing the effects of climate variables on nests from different species at shared nesting grounds. We used Generalized Additive Models (GAMs) to explore how air temperature, sand temperature, precipitation and humidity affect reproductive outputs of in situ nests of loggerhead (Caretta caretta), leatherback (Dermochelys coriacea), hawksbill (Eretmochelys imbricata) and olive ridley (Lepidochelys olivacea) sea turtles. Our results show variability in the response of species that nest at the same location with the same seasonality. We conclude that embryos response to local climate is also species specific and therefore, conservation efforts at nesting grounds should take into consideration not only the conditions at each site but also the requirements of each species.
- O boreout nos profissionais do setor da saúde: o caso dos agrupamentos de centros de saúde do Algarve (ACeS)Publication . Faria, Olinda Margarida Paiva; Brás, Maria; Viegas, MargaridaEsta dissertação investiga a Síndrome de Boreout entre os profissionais de saúde dos Agrupamentos de Centros de Saúde (ACeS) do Algarve com o objetivo de identificar a sua prevalência e explorar a sua relação com o stress ocupacional. A pesquisa utilizou uma amostra de 268 profissionais e aplicou a Work Boreout Scale (WBOS), a qual foi adaptada e validada para o contexto português. Os resultados revelaram uma elevada prevalência de Boreout, ainda que em níveis de severidade considerados moderados na maioria dos casos. Além disso, foi constatada a existência de diferenças significativas nos níveis de Boreout e de stress ocupacional entre diferentes categorias de profissionais de saúde. Foi também verificada uma correlação significativa, embora fraca, entre os níveis de Boreout e de stress ocupacional. Este estudo evidencia a necessidade de intervenções organizacionais sistemáticas que mitiguem os efeitos do Boreout e que promovam um ambiente de trabalho salutar e alinhado com as expetativas profissionais dos funcionários.
- Políticas educativas na Guiné-Bissau, acesso à educação e sucesso escolar: estudo de caso no Liceu Padre António Grillo-BambadincaPublication . Mendes, Diogo Francisco; Guerreiro, António Manuel da Conceição; Nunes, Sofia Helena GagoA presente investigação tem por tema as políticas educativas guineenses, especificamente as políticas educativas na Guiné-Bissau, acesso à educação e sucesso escolar, um estudo de caso no liceu Padre António Grillo-Bambadinca, realizado no âmbito de mestrado em Gestão e Administração Escolar da Escola Superior de Educação e Comunicação da Universidade do Algarve. No quadro teórico do estudo realça-se o percurso político da República da Guiné-Bissau, após a proclamação da independência, a base legislativa do sistema educativo guineense, bem como um olhar sobre as questões relacionadas com o acesso e o sucesso escolar no contexto educativo, com enfoque particular na realidade guineense. A investigação tem como objetivo geral conhecer e analisar as políticas educativas na Guiné-Bissau e o seu contributo para o acesso e o sucesso escolar na perspetiva de professores com experiência educativa no liceu em estudo. Procura-se, por meio dos testemunhos dos professores participantes, indagar sobre o tema das políticas educativas e do acesso e sucesso escolar, na realidade guineense, através uma metodologia qualitativa no paradigma interpretativo. Para inquirição dos respondentes recorreu-se a uma entrevista estruturada com questões abertas, respondida por escrito. Após a análise dos dados conclui-se que, devido ao sucessivo incumprimento e adiamento da efetivação das políticas educativas, motivada por constantes crises políticas e institucionais, o acesso à educação não é universal e o sucesso escolar é deficitário, prevalecendo mais o insucesso entre as crianças e jovens guineenses. Os resultados evidenciam também o contributo das organizações internacionais no acesso e na promoção do sucesso escolar.

- Destination image: A comparative study between Obudu Mountain Resort and Tinapa, NigeriaPublication . Ivongbe, Jude Rukevwe; Agapito, Dora; Guerreiro, Maria ManuelaTourism is one of the socio-economic and cultural activities involving the movement of people within a country. This research focuses on a comparative study of the destination image of Obudu Mountain Resort and Tinapa Resort from the perspective of visitors. Destination image is a key element influencing the decision-making process and satisfaction, which can contribute to destination competitiveness. Destination image incorporates elements related to cognitive, affective, and conative components, shaping tourists' perceptions. Landscapes and cultural heritage diversity place Nigeria high in terms of tourism development potential, but comparative studies between specific destinations in the country are missing. Following a quantitative approach, an online questionnaire was implemented among visitors to Obudu Mountain Resort and Tinapa Resort. The findings indicate that whereas the two places are valued for their natural beauty, Tinapa would attract more repeat visitors because of recreational activities and facilities. Obudu would attract those who desired to enjoy a serene environment with rich cultural displays. Cognitive images were more related to modern infrastructural facilities and activities regarding Tinapa, while Obudu was more associated with quiet scenery. The affective images related to Tinapa include feelings of excitement and pleasure, while those related to Obudu encompass emotions of tranquillity and relaxation. Conative components results show that there is a higher revisit intention for Tinapa. Some tourism management recommendations for decision-makers are related to enhancing safety, diversifying activities, and exploiting cultural and natural features. For sustainable tourism to be a reality, a collaborative effort has to be made by the government, communities, and stakeholders. It improves destination image, hence attracting more visitors promoting sustainable tourism development by understanding tourist perceptions.
