- Surviving the culture shock syndrome: the role of responsible leadership and emotional intelligence in enhancing expatriates’ performancePublication . Marques, Tânia M. G.; Miska, Christof; Crespo, Cátia Fernandes; Jesus, JoãoExpatriates are increasingly being challenged to execute their roles with a higher sense of responsibility. However, there is a lack of studies that have empirically examined the impact of the recent responsible leadership (RL) approach on expatriates’ performance. Using Anxiety and Uncertainty Management Theory, this study examines the relationship between RL and expatriates’ performance (EP) and the influence of the culture shock (CS) on the relationship. In addition, the moderation effect of both emotional intelligence (EI) and cultural intelligence (CQ) are also examined. A web-based survey was administered to collect data from a sample of 204 expatriates and PLS-SEM was used to analyse the data. The results show that RL is negatively associated with culture shock and culture shock is negatively associated with expatriate performance. Moreover, RL is positively associated with expatriate performance and the results show that this relationship is moderated by the expatriate’s emotional intelligence. Overall, we emphasize the reducing anxiety and uncertainty ability of expatriates’ supervisors when supervisors demonstrate RL. Moreover, although cultural intelligence has been emphasized considerably in extant research, it seems less relevant than emotional intelligence when RL is concerned in the expatriation setting. Thus, we provide a different perspective for studying leadership complexities in the expatriation context. Our study contributes to illustrate that responsible leadership can reduce psychological complexities and increase performance in international assignments, highlighting the reinforcement role of expatriates’ EI for the success.

- Do conhecimentos tácito ao conhecimento explícito: evidências da Newsletter #2 do Grupo Projeto CrechePublication . Dias, Isabel SimõesEste capítulo visa refletir sobre a transformação do conhecimento (do conhecimento tácito ao conhecimento explícito) no contexto da formação contínua de educadores de infância, no Grupo Projeto Creche (GPC), uma comunidade de prática da Escola Superior de Educação e Ciências Sociais/Politécnico de Leiria (ESECS/PL). Assumindo-se como um estudo exploratório de índole qualitativo, recorre à análise documental para aceder aos dados. Os resultados advindos da análise de conteúdo da newsletter #2 “A criança em contexto de Creche”, são interpretados de acordo com os focos da newsletter (a criança dos 0 aos 3 anos; a creche enquanto contexto educacional; o papel do educador na creche), à luz das ideias de Nonaka e Takeuchi (1997) sobre a espiral do conhecimento e dos estudos já realizados sobre o GPC (e.g., Grupo Projeto Creche, 2022). Os resultados permitem identificar saberes no âmbito da Educação de Infância advindos de experiências vivenciadas em contexto de creche. Infere-se que este conhecimento tácito, não formalizado, quando socializado, externalizado, debatido e combinado no seio do GPC terá sido internalizado e transformado em conhecimento explícito. Acredita-se que estes resultados possam contribuir para uma reflexão sustentada sobre o papel das comunidades de prática na construção de conhecimento e desenvolvimento profissional docente.
- PrefácioPublication . Nobre, CristinaA propósito de Afonso Lopes Vieira (1878-1946) e do livro de homenagem - IN MEMORIAM - que lhe foi consagrado logo em 1947, e do qual se fez uma edição fac-similada em 2023, faz-se uma reflexão necessária sobre os remanescentes culturais do passado que transitam para o presente e futuro e como se constroem eles na ‘bolsa de valores’ da cultura deste novo século.

- Quaternion Hyperbolic Fourier Transforms and Uncertainty PrinciplesPublication . Ferreira, M.; Morais, J.The present study introduces the two-sided and right-sided Quaternion Hyperbolic Fourier Transforms (QHFTs) for analyzing two-dimensional quaternion-valued signals defined in an open rectangle of the Euclidean plane endowed with a hyperbolic measure. The different forms of these transforms are defined by replacing the Euclidean plane waves with the corresponding hyperbolic plane waves in one dimension, giving the hyperbolic counterpart of the corresponding Euclidean Quaternion Fourier Transforms. Using hyperbolic geometry tools, we study the main operational and mapping properties of the QHFTs, such as linearity, shift, modulation, dilation, symmetry, inversion, and derivatives. Emphasis is placed on novel hyperbolic derivative and hyperbolic primitive concepts, which lead to the differentiation and integration properties of the QHFTs. We further prove the Riemann–Lebesgue Lemma and Parseval’s identity for the two-sided QHFT. Besides, we establish the Logarithmic, Heisenberg–Weyl, Donoho–Stark, and Benedicks’ uncertainty principles associated with the two-sided QHFT by invoking hyperbolic counterparts of the convolution, Pitt’s inequality, and the Poisson summation formula. This work is motivated by the potential applications of the QHFTs and the analysis of the corresponding hyperbolic quaternionic signals.
- 2ARTs – Decision Support System for Exercise and Diet Prescriptions in Cardiac Recovery PatientsPublication . Pereira, Andreia Alexandra Sousa; Martinho, Ricardo Filipe Gonçalves; Rijo, Rui Pedro Charters Lopes; Grilo, Carlos Fernando de AlmeidaThe global health care system is faced with a variety of complicated challenges, ranging from limited access and increasing expenses to an aging population causing increased pressure on healthcare systems. Healthcare professionals are seeking alternative approaches to provide fair access and sustain high-quality care for everyone as a result of these challenges. Patients have historically been restricted from accessing essential healthcare services due to traditional barriers like geographic distance, financial and resource limitations. Innovative solutions to these problems are starting to take shape, thanks to the growth of eHealth platforms that use technology to improve patient care. Through a comprehensive study of existing solutions in the healthcare domain, particularly in cardiology, we identified the need for a Decision Support System (DSS) that would empower physicians with valuable insights and facilitate informed physical and diet prescribing practices into Cardiac Rehabilitation Programmes (CRPs). The major goal of 2ARTs’ project is to create and implement a cardiac rehabilitation platform into a hospital's infrastructure. A key aspect of this platform is the integration of a decision support system designed to provide physicians with valuable information when prescribing individualized treatment prescriptions for each patient, minimizing the potential of human error. The DSS uses algorithms and predictive models to classify patients into distinct groups based on their features and medical history. This classification provides critical insights and additional knowledge to doctors, allowing them to make informed judgments regarding the most effective treatment options for each patient's cardiac rehabilitation journey. By using the power of data-driven analytics and machine learning, the DSS enables doctors to better understand each patient's needs and personalize treatment actions accordingly. In order to achieve the best possible results aligned with the goals of the project, a variety of approaches based on comprehensive studies were explored, specifically feature selection and feature reduction methods, where their performance metrics were evaluated, seeking the most effective solution. It was through this thorough analysis that Principal Component Analysis (PCA) emerged as the standout choice. PCA not only demonstrated superior outcomes in evaluation metrics, but also showcased excellent compatibility with the selected clustering algorithm along with the best results after an expert analysis. Moreover, with the analysis of the data types and features the dataset had, the K-Means algorithm produced the best results and was more adaptable to our dataset. We were able to identify useful insights and patterns within the data by employing both PCA and K-Means, opening the way for more accurate and informed decision-making in the 2ARTs project.

The COVID-19 pandemic has highlighted the consequences of environmental mismanagement, underscoring the urgency of sustainable practices. This study explores the potential for building environmentally sustainable and regenerative foundations for society, fostering green growth. New ocean farming technologies and algae research hold immense promise across various domains, including health, biomaterials, medicine, ecosystem services, food production, circular economies, global industries, and design applications to name a few. By sequestering carbon dioxide from the atmosphere, the oceans mitigate climate change, supply food, and support vital economic sectors like tourism and fishing, while nurturing diverse ecosystems. In the pursuit of environmental sustainability, the world needs eco-friendly and sustainable industries like regenerative ocean farming and land-based sustainable agriculture. Additionally, the oceans’ economic value, stemming from their rich biodiversity, underscores their importance. This thesis addresses a critical need for an accessible online platform that consolidates information on ocean-related innovations. The platform aims to inspire individuals to develop solutions, fostering innovation in environmental recovery, healthcare, design, food production, industry, and the ocean economy. By providing an Open Educational Resource (OER) integrated with crowdfunding capabilities, users can learn, share, fund, and innovate, thereby advancing sustainable economic and environmental solutions. Blockchain technology and cryptocurrencies offer the potential for decentralized governance, increasing user engagement and trust within the platform. The envisioned platform seeks to empower individuals to drive sustainable change and contribute to a healthier planet.
- CASE ID DETECTION IN UNLABEL LED EVENT LOGS FOR PROCESS MININGPublication . Vicente, André Alexandre dos Santos; Rijo, Rui Pedro Charters Lopes; Martinho, Ricardo Filipe Gonçalves; Grilo, Carlos Fernando de AlmeidaIn the realm of data science, event logs serve as valuable sources of information, capturing sequences of events or activities in various processes. However, when dealing with unlabelled event logs, the absence of a designated Case ID column poses a critical challenge, hindering the understanding of relationships and dependencies among events within a case or process. Motivated by the increasing adoption of data-driven decision-making and the need for efficient data analysis techniques, this master’s project presents the "Case ID Column Identification Library" project. This library aims to streamline data preprocessing and enhance the efficiency of subsequent data analysis tasks by automatically identifying the Case ID column in unlabelled event logs. The project’s objective is to develop a versatile and user-friendly library that incorporates multiple methods, including a Convolutional Neural Network (CNN) and a parameterizable heuristic approach, to accurately identify the Case ID column. By offering flexibility to users, they can choose individual methods or a combination of methods based on their specific requirements, along with adjusting heuristic-based formula coefficients and settings for fine-tuning the identification process. This report presents a comprehensive exploration of related work, methodology, data understanding, methods for Case ID column identification, software library development, and experimental results. The results demonstrate the effectiveness of the proposed methods and their implications for decision support systems.
- A Resposta Social: Acolhimento Familiar de Pessoas Idosas Famílias de AcolhimentoPublication . Henriques, Joana Ferreira Gonçalves de Oliveira; Margarido, Emanuel João Fonseca Franco RibeiroO Acolhimento Familiar de Pessoas Idosas é uma resposta social, prevista na lei para acolher pessoas idosas de forma temporária ou permanente e a tempo completo ou a tempo parcial. Assim, apesar de se tratar de uma resposta há já algum tempo implementada, ainda é pouco divulgada e explorada a fim de funcionar na plenitude como previsto legislativamente. É uma resposta que, por enquanto, tem pouco impacto na sociedade, pese embora, num futuro próximo, se acredite que será vista como uma alterativa fundamental e pertinente para colmatar as dificuldades sentidas pelos nossos idosos e suas famílias, nomeadamente no que diz respeito ao fraco poder económico e à inexistência de vagas nas restantes respostas institucionais. Fruto do processo de envelhecimento, surgem necessidades e vulnerabilidades a ter em conta, e nesse sentido é fulcral que os apoios e respostas sociais se adaptem a essa faixa etária, ao longo dos tempos. Nesse sentido, o presente estudo pretende perceber o funcionamento e a respetiva necessidade e importância da existência desta resposta social. A metodologia assenta numa abordagem qualitativa, sendo um estudo de caso, em que foram aplicados métodos de investigação: pesquisa documental relativamente à informação disponibilizada que rege a resposta social; entrevista semiestruturada à diretora técnica de uma Instituição Particular de Solidariedade Social- IPSS (instituição de enquadramento); inquérito por questionário a famílias de acolhimento e a idosos. De seguida, procedeu-se ao tratamento dos dados através de uma análise de conteúdo, estruturada em categorias de análise (entrevista) e através da interpretação de gráficos e tabelas extraídos dos resultados dos inquéritos por questionário. Os resultados evidenciam que há um longo caminho a percorrer no sentido de divulgar, rever legislação e apelar ao apoio, à criação e readaptação das casas de acolhimento, integrando-as em instituições de enquadramento, de forma que possam dotar as famílias de conhecimentos, acautelando assim as necessidades dos idosos, apostando num meio familiar e personalizado. As conclusões revelam que a intervenção relativa às Famílias de Acolhimento se divide em duas perspetivas: uma atribui grande importância e necessidade da existência desta resposta social, tendo sido a escolha/preferência da população idosa. A outra intervém no sentido inverso, pelo facto de apesar de haver a necessidade desta resposta social, esta ainda não consegue satisfazer profissionalmente as famílias que acolhe, perdendo o interesse em se enquadrar legalmente, alegando não ser aliciante do ponto de vista do mercado de trabalho.
