Mediação Intercultural em Contexto Escolar
No full textA sociedade e a escola contemporânea são cada vez mais complexas e multiculturais (Vieira e Vieira, 2017), logo, impõe-se hoje à escola novos desafios para responder à crescente diversidade e multiplicidade de divergências. Para tal, são imprescindíveis lideranças capazes que saibam dirigir as instituições educativas com sabedoria e que estejam capacitadas para construir estratégias para que professores e alunos convivam de forma natural com as diferenças sociais, culturais e pessoais.
Apresenta-se, no âmbito desta investigação, um estudo que procura perceber a influência do tipo de liderança e quais a(s) prática(s) de mediação intercultural, desenvolvidas na Escola Básica 2,3 ciclos de Gualtar. Como ocorrem, a forma como são percebidas e o seu impacto no desempenho dos alunos e da organização escolar foram alguns dos aspetos que procurámos entender.
Considerando a liderança e a mediação como conceitos chave deste trabalho, torna-se fundamental a análise do contexto e da comunicação organizacional, no que concerne à estrutura, às relações de trabalho existentes, ao clima, à cultura organizacional desenvolvida, ao tipo de liderança exercida e às práticas de mediação existentes.
Em termos metodológicos, assumiu-se como fundamental o paradigma interpretativo, compreensivo/fenomenológico, cujo objetivo é a compreensão da realidade em estudo, tal como ela é vivida pelos sujeitos. A recolha de dados foi realizada através da observação direta e das entrevistas individuais semiestruturadas à Direção da Escola, aos professores e psicóloga que assumem o papel de mediadores.
Esta investigação permite concluir, que ainda há um longo caminho a percorrer no que concerne à implementação de práticas de mediação em contexto escolar, e que a existência da inclusão da figura do mediador intercultural é notória, constituindo-se uma mais valia não apenas nos alunos, mas também nas famílias, escola e comunidade, na medida em que adota práticas diferenciadas, transformadoras e empoderadoras da diversidade que habita atualmente na escola.
Reconheceu-se, que a diversidade na escola aumentou, testemunhando que a interculturalidade é uma porta aberta para a criação de laços e pontes entre os alunos, comungando da cultura do “outro”, numa oportunidade de conhecimento e de novas aprendizagens sociais e culturais. Percebeu-se ainda, que os professores, a Direção e psicóloga são mediadores interculturais que trabalham em rede, adotando estratégias diferenciadas e recorrendo às diferentes formas de comunicação para diminuir a tensão, o conflito e a indisciplina
Renewable Energy and Socio-Economic Transformation: Three Case Studies
No full textThis article belongs to the Special Issue Achieving Carbon Neutrality: Recent Progress of Sustainable Energy Economic, Energy Policy and Energy Transition.Portugal’s renewable energy transition plays a pivotal role in addressing climate change, enhancing energy security, and promoting sustainable development. This study examines the socio-economic impacts of renewable energy policies in Portugal from 2014 to 2022, with a focus on financial performance, employment trends, and gender equity. Utilizing financial assessments from the Orbis database and input–output analysis, the research examines three companies—EDP, E-Redes, and Logical Gravity—classified under NACE Rev. 2 code 3513. The study finds that investments in renewable energy improved profitability and solvency, especially during recovery phases, reflecting the sector’s financial resilience. Larger firms like EDP experienced employment growth, while smaller firms faced more volatility, highlighting the need for targeted support. Despite progress, gender disparities and pay gaps persist, underscoring the need for gender-sensitive policies. This research provides valuable insights for policymakers seeking to ensure a just and sustainable energy transition, emphasizing strategic investments, workforce adaptation, and inclusivity.This research is financed by National Funds of the FCT—Portuguese Foundation for Science and Technology within the project «UIDB/04928/2020» and, under the Scientific Employment Stimulus—Institutional Call CEECINST/00051/2018
Algoritmos de Classificação Multiclasse via SVM para Apoio ao Diagnóstico a partir de Dados do Teste de Esforço Cardiopulmonar (CPET)
No full textO Teste de Esforço Cardiopulmonar (CPET) é uma ferramenta vital para o diagnóstico
funcional, mas a aplicação de modelos de aprendizagem automática é frequentemente
limitada pela escassez de séries temporais completas para diversas condições clínicas.
Esta dissertação aborda esta lacuna, partindo de um framework de classificação baseado
em Support Vector Machines (SVM) e na Transformada Wavelet Discreta (DWT),
originalmente desenvolvido para três classes (Insuficiência Cardíaca (IC), Síndrome
Metabólica (SM) e Saudáveis (S)).
O objetivo central foi expandir esta metodologia para um cenário mais complexo de
cinco classes, através da geração de Dados Semi-Sintéticos para os grupos de Limitação
Pulmonar (LP) e Limitação Musculoesquelética (LM), guiada por parâmetros estatísticos
de pacientes reais. Subsequentemente, para validar a eficácia da Transformada
Wavelet Discreta (Discrete Wavelet Transform) (DWT) neste novo contexto, foi conduzida
uma análise comparativa, avaliando o desempenho do modelo contra três métodos
alternativos de extração de características: a Transformada de Fourier de Curto Tempo
(Short-Time Fourier Transform) (STFT), a Transformada Wavelet por Pacotes (Wavelet
Packet Transform) (WPT) e a Decomposição por Modos Empíricos (Empirical Mode Decomposition)
(EMD). Todos os modelos foram avaliados sob um protocolo experimental
consistente para garantir uma comparação justa.
Os resultados da análise comparativa foram consistentes. O modelo SVM-Linear-MW5,
que utiliza a DWT, alcançou uma acurácia de 93.60% e um F1-Score de 84.14%, um
desempenho que se destacou em relação ao das outras transformadas. A análise demonstrou
que a STFT foi a alternativa mais competitiva (F1-Score de 74.25%), enquanto
a WPT e a EMD não se mostraram tão eficazes para este problema.
Este trabalho conclui que a combinação de dados semi-sintéticos com a extração
de características via DWT é uma abordagem viável para a expansão de modelos de
diagnóstico. A metodologia de referência foi expandida para cinco classes e, na análise
comparativa realizada, a sua abordagem de processamento de sinal obteve o desempenho
mais elevado entre as técnicas testadas, o que estabelece um baseline sólido para
futuras investigações na área, incluindo a otimização de Hiperparâmetros.Cardiopulmonary Exercise Testing (CPET) is a vital tool for functional diagnosis, yet
the application of machine learning models is often limited by the scarcity of complete
time-series across clinical conditions. This dissertation addresses that gap by extending
a classification framework based on Support Vector Machines (SVM) and the Discrete
Wavelet Transform (DWT), originally developed for three classes (Heart Failure, Metabolic
Syndrome, and Healthy).
The central goal was to scale this methodology to a five-class scenario by generating
semi-synthetic data for Pulmonary Limitation and Musculoskeletal Limitation, guided
by summary statistics from real patients. To assess the effectiveness of DWT in this
expanded setting, a comparative study was conducted against three alternative featureextraction
methods: Short-Time Fourier Transform (STFT), Wavelet Packet Transform
(WPT), and Empirical Mode Decomposition (EMD). All models were evaluated under
a consistent experimental protocol to ensure fair comparison.
Results were consistent: the SVM-Linear-MW5 model, using DWT-based features,
achieved 93.60% accuracy and an F1-score of 84.14%, outperforming the alternatives.
STFT was the most competitive contender (F1-score of 74.25%), while WPT and EMD
were less effective for this problem.
This work concludes that combining semi-synthetic data with DWT-based feature
extraction is a viable path to expand diagnostic models. The reference methodology
was successfully extended to five classes and set a strong baseline for future research,
including hyperparameter optimisation
Passion, Motivation, and Well-Being in Young Footballers: A Systematic Review
No full textBackground: Psychological well-being is crucial for the development and performance of young athletes. This systematic review aims to synthesize the available scientific evidence on the relationship between passion (harmonious and obsessive), basic psychological needs (BPNs), motivation, affect (positive and negative), and life satisfaction in young football (soccer) players. Methods: A systematic literature review was performed, following the PRISMA 2020 (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The search was conducted in the Web of Science, Scopus, ERIC, and SportDiscus databases, using a comprehensive strategy that combined keywords related to football, youth, passion, motivation, and well-being. Two independent reviewers performed article screening, eligibility assessment, and data extraction. The methodological quality of the included studies was determined using two different tools. Results: Nine studies met the inclusion criteria and were analyzed in detail. The results consistently indicate that harmonious passion is associated with greater fulfillment of BPNs, positive affect, and overall life satisfaction. In contrast, obsessive passion was linked to negative outcomes such as burnout and emotional dysregulation. The available evidence suggests a positive association of harmonious passion with motivation and well-being, and an association of obsessive passion with psychological distress. Conclusions: Within the delimited scope, the evidence suggests that harmonious passion is an important construct positively associated with the well-being and motivation of young footballers, while obsessive passion is associated with adverse outcomes. Research in this area is scarce, showing methodological diversity and heterogeneous samples, which limits the generalizability of the findings. Future research should prioritize longitudinal designs and interventions to promote harmonious passion and the satisfaction of BPNs.This work was funded by National Funds by FCT—Foundation for Science and Technology under the following project UID/04045: Research Center in Sports Sciences, Health Sciences, and Human Development.info:eu-repo/semantics/publishedVersio
Assessing High-Value Bioproducts from Seaweed Biomass: A Comparative Study of Wild, Cultivated and Residual Pulp Sources
No full textThis study aimed to evaluate the biochemical composition and bioactivities of biomass derived from wild (Laminaria ochroleuca and Saccorhiza polyschides) and cultivated (Macrocystis pyrifera) kelps, as well as industrially extracted residual pulp from M. pyrifera, to assess the potential production of high value bioproducts. All samples had a low lipid content, with M. pyrifera having the lowest (1.3% dw) and S. polyschides showing the highest value (3.3%). Fatty acids such as palmitic acid (C16:0), oleic acid (C18:1n-9 cis), alpha-linolenic acid (ALA, C18:3n-3), and eicosapentaenoic acid (EPA, C20:5n-3) were present, with the residual pulp having a distinctive n-6/n-3 ratio of less than one. The protein content was around 9% dry weight (dw) in all samples. The residual pulp and S. polyschides had the highest polyphenol content, with 4.86 and 4.94 mg GAE·g−1 extract, respectively. Hydroethanolic extracts (30–70%) confirmed Fe3+ reducing activity (FRAP) in all samples. These findings offer valuable insights on the biochemical composition and bioactivity of the kelp species under study and the residual kelp biomass (pulp), underlining their significant potential for applications in the field of Blue Biotechnology.This work had the support of national funds through Fundação para a Ciência e Tecnologia (FCT), within the scope of the projects UID/04292/MARE-Centro de Ciências do Mar e do Ambiente and LA/P/0069/2020 (ARNET Associate Laboratory) (https://doi.org/10.54499/LA/P/0069/2020), and also the doctoral grant awarded to Marta V.

[Lideranças Intermédias e Educação Inclusiva – Um estudo de caso]
No full textO sistema educativo está em constante mudança, impulsionado por transformações políticas, demográficas e económicas. Nesse contexto, as escolas têm recebido cada vez mais autonomia, permitindo-lhes oferecer a melhor educação possível para Todos. Para que essa autonomia se traduza em sucesso, o papel dos líderes intermédios torna-se essencial, garantindo o bom funcionamento da organização. São eles os responsáveis por motivar, envolver e mobilizar os liderados dentro de uma filosofia inclusiva, capaz de promover o sucesso educativo de cada aluno. O presente relatório parte de uma questão inicial “Como estava a ser interiorizada e operacionalizada, por diferentes níveis de liderança na escola, a perspetiva subjacente de Educação Inclusiva?”. Na tentativa de responder a esta questão definiram-se como objetivos da investigação: i) identificar práticas inclusivas desenvolvidas na promoção da EI no AE, ii) analisar a perceção que os líderes intermédios têm do seu papel na implementação de práticas inclusivas promotoras de EI e iii) refletir sobre o contributo das práticas de EI desenvolvidas no AE. A análise dos dados recolhidos, através de entrevistas, evidenciou que a resposta a uma política educativa inclusiva, que pretende a construção de uma escola para Todos, deve preconizar práticas pedagógicas que valorizem um trabalho mais colaborativo, diversificar os recursos metodológicos, flexibilizar os currículos e investir na formação docente para valorizar a autonomia do aluno na construção do seu processo educativo

Is the light at the end of the tunnel bright? Associations between preference and tolerance of the intensity, basic psychological needs and behaviour in exercise context
No full textIn recent years, sedentary behaviour and physical inactivity have seen an evident increase. Many individuals who embark on an exercise regimen end up leaving it within the first three to six months, often citing barriers such as a lack of time or motivation. Research shows that the pleasure and enjoyment derived from exercise play a crucial role in preventing people from giving up. This suggests that theories related to the emotional aspects of exercise, including an individual’s exercise intensity preference and tolerance, should be integrated into broader motivation theories such as Self-Determination Theory (SDT). This chapter aims to provide a theoretical framework for these theories, emphasised by empirical evidence and proposes potential avenues for future research.info:eu-repo/semantics/publishedVersio
