- Aprendizado por transferência para correção automática de redaçãoPublication . Silveira, Igor Cataneo; Ribeiro, Eugénio; Mamede, Nuno; Baptista, JorgeA tarefa de Correção Automática de Redação tem despertado crescente interesse na ´área de processamento de texto em português. Entre os conjuntos de dados disponíveis, destaca-se um corpus de redações narrativas produzidas por alunos do 5º ao 9º ano do ensino fundamental no Brasil. Essas redações são avaliadas segundo quatro competências: registro formal, coerência temática, estrutura retórica narrativa e coesão textual. Este trabalho explora a criação de um sistema baseado em conhecimentos derivados de outro dataste (desenvolvido com base em textos produzidos para o ENEM) e de outras tarefas (cálculo de complexidade textual e análise de legibilidade). O sistema desenvolvido combina modelos neurais, características (features) curadas calculadas por programas de análise textual e seleção de fatures em um modelo de Aprendizado em Dois Estágios. Com isso, foi possível elevar a performance em relação ao estado da-arte, nomeadamente, em 9% para a primeira competência, 5,5% para a terceira e 8,9% para a quarta.
- Brand hate semiotics: hate as a story theory. Netnographic approach during the war on GazaPublication . Assoud, Mohamed; Berbou, Lahoucine; Vieira, Luís SérgioPurpose – This study aims to investigate brand hate semiotics among Muslim and Arabic-speaking consumers during the 2023 war on Gaza, exploring traits associated with hated and boycotted brands within a sociopolitical context. Design/methodology/approach – The research uses semiotic analysis and a netnographic approach to examine 3,000 public consumer-generated content linked to the hashtag # عطاق) boycott in Arabic) from Instagram and Facebook. Findings – Brands such as McDonald’s, KFC, Coca-Cola and Starbucks, which were subjected to hate and boycotts, are linked to negative associations and narratives, including The Stranger, The Faceless Foe, The Enemy of God and The Criminal. User-generated content significantly influences brand boycotts among Muslim and Arabic-speaking consumers. Research limitations/implications – Future research should explore additional sociopolitical contexts and demographics to generalize the findings further. Practical implications – Understanding the semiotic drivers of brand hate can help marketers develop effective crisis management and brand recovery strategies tailored to specific cultural contexts. Social implications – The findings highlight the impact of sociopolitical events on consumer behavior, emphasizing the need for brands to be aware of their cultural and ethical stances in global markets. Originality/value – This research contributes to brand hate theory by using the “hate as a story” lens, offering a unique theoretical perspective. It systematically explores the semiotic aspects of brand hate and pioneers’ semiotic analysis and netnography in this field. The study also addresses the underrepresentation of Muslim and Arabic-speaking consumers in brand hate literature.

- Gamification on mathematics engagement and motivation in secondary school and higher education: a systematic review and meta-analysisPublication . Ratinho, Elias; Figueiredo, Mauro; Estêvão, Maria Dulce da Mota Antunes de Oliveira ; Faísca, Luís; Martins, CátiaThis systematic review and meta-analysis examined the effects of gamification on students’ motivation and engagement in mathematics at the secondary and higher education levels. A literature search (April 2025) followed by an updated search (November 2025) across ten databases identified 45 studies for qualitative synthesis and 11 for meta-analysis. The review followed PRISMA 2020 guidelines with a pre-registered protocol, and study quality was appraised with the Mixed Methods Appraisal Tool. Meta-analytic results using a three-level Correlated and Hierarchical Effects model with robust variance estimation showed a significant small-to-moderate positive effect on motivation (g = .383, 95% CI [.11, .66], p = .0218). Motivation was assessed more consistently than engagement that could not be included in the meta-analysis due to the lack of validated measures. The systematic review indicates that gamification supports motivation and engagement, with only four studies reporting negative effects. Most interventions used digital platforms (e.g., Kahoot!; Classcraft) and common game elements such as points, leaderboards and instant feedback. Overall, gamification appears promising for enhancing motivation and engagement in mathematics when designs are aligned with students’ needs, balancing competition with mastery and cooperation. Therefore, educators should limit excessive competition and prioritize personal progress and cooperative tasks that foster social interaction. Future studies should employ validated measures, larger samples, and examine both motivation and engagement to strengthen the evidence base and guide effective implementation in education.

- Measuring parental school involvement: a systematic reviewPublication . Belém, Helena Sofia Mocho Alcaparra; Martins, Cátia; dos Santos, Rita Alexandra Mendes; Ratinho, Elias; Nunes, CristinaAbstract: Parental school involvement (PSI) is a multidimensional construct that significantly influences children’s academic adjustment and overall development. However, inconsistencies persist in its definition and measurement, with researchers operationalizing PSI through a varied of parental activities. This study aimed to (1) identify PSI instruments and their theoretical models and (2) evaluate their psychometric properties. Following PRISMA guidelines (PROSPERO ID CRD42023451091, registered August 2023), this systematic review examined six databases (Web of Science, ERIC, MEDLINE, Psychology and Behavioral Sciences Collection, PsycArticles, and PsycInfo), analyzing quantitative studies from 2000 to 2024. Inclusion criteria encompassed instruments designed for parents, teachers, or children aged 6–15 and published in peer-reviewed journals in English, Portuguese, Spanish, or French. From an initial pool of 490 records, 38 studies were included, yielding 43 instruments: 23 for parents, 15 for children, and 5 for teachers. Seven instruments followed Epstein’s model, while nine followed the Hoover-Dempsey and Sandler framework, underscoring the prominence of these theoretical approaches. The study quality, assessed with MMAT, was generally moderate to high. Despite an exhaustive search effort, it is possible that some relevant instruments were not identified. Nevertheless, this review advances the understanding of PSI operationalization, promotes more consistent and replicable assessments, enhances alignment between instruments and study objectives, and strengths the validity of findings derived from these tools.
- Multilingual realities and language policyPublication . Conceição, Manuel CélioThe growing complexity of linguistic environments in the twenty-first century reflects global processes such as urbanisation, migration, political transformation and educational reform. In an increasingly interconnected and linguistically diverse world, language functions not merely as a tool for communication but as a complex and contested site of identity, governance and global participation; language has become both a mirror and a driver of change.
- Noticias da homenaxe a Rosalía de Castro no Porto (1954)Publication . Novoa Fernández, OliviaTranscorridos 70 anos, a escultura de Rosalía resiste como lugar de memoria nun entorno que hoxe dista de ser o locus amoenus descrito nos discursos do acto inaugural celebrado en 1954 na Praza da Galiza. A perennidade da pedra, en granito rosa, parece simbolizar, alén dunha paisaxe compartida polo noroeste peninsular, a fortaleza dos lazos que unen o Norte de Portugal e Galicia. Un vínculo, moitas veces vencellado ao ámbito cultural, ao lingüístico e ao literario, mais tamén ao político e as súas consecuentes instrumentalizacións. Este texto propón un ollar ao pasado a través das noticias da inauguración do monumento publicadas nos principais xornais galegos e nos portugueses Jornal de Notícias e O Comércio do Porto. Seguindo algúns parámetros da análise de contido, comparouse a importancia e relevancia dada ao acontecemento nun total de 18 noticias. Esta primeira abordaxe complementouse aínda co estudo do discurso en relación co contexto político a fin de investigar a proxección da imaxe da poeta e o adoutrinamento da fraternidade peninsular.
- Positive residential care integration scale: Portuguese adaptation and validationPublication . Simão, Ana; Martins, Cátia; Ratinho, Elias; Kothari, Brianne H.; Nunes, CristinaYoung people in residential care settings hold distinct preferences regarding their relationships with key adults, including caseworkers and caregivers. However, their perspectives are not consistently assessed or effectively integrated into case planning. Evaluating this integration is essential for fostering positive adjustment and placement stability. Given that residential care represents the predominant child welfare intervention in Portugal, this study adapts and validates an existing instrument for use with youth in residential care institutions, providing evidence of its validity and reliability. Self-report questionnaires-the Positive Residential Care Integration (PRCI) scale (an adapted Positive Home Integration scale) and Strengths and Difficulties Questionnaire-were administered to 511 youth (279 girls and 232 boys), aged 12 to 24 years, across 46 Portuguese residential care institutions. The study examined the face validity, discriminant validity, and reliability of the PRCI scale. Confirmatory factor analysis indicated good model fit, supporting a unidimensional six-item structure. Correlation analyses demonstrated associations with psychological adjustment and sociodemographic variables. The PRCI scale showed satisfactory psychometric properties, confirming its reliability for assessing youth integration in residential care. Cross-gender measurement invariance was also confirmed. These findings underscore the instrument's relevance and validity for evaluating integration within residential settings and provide valuable guidance for caregivers, professionals, and caseworkers in child welfare services.
- Psychological profile of adolescents living in residential care: implications for evidence-based interventionsPublication . Simão, Ana; Martins, Cátia; Nunes, CristinaPsychological adjustment in adolescents living in residential care settings is a multidetermined process. This study explores the psychological adjustment of adolescents living in residential care, aiming to identify distinct psychosocial profiles. The sample comprised 433 adolescents (196 boys and 237 girls), aged 12 to 18 years, from 46 Portuguese institutions. Participants self-reported on key variables, including social support, coping strategies, emotion regulation, Dark Triad traits, attachment, and institutional integration. Hierarchical cluster analysis revealed three theoretically coherent profiles, differentiated by number of close friends, duration of institutionalization, substance use, and psychiatric medication. These profiles reflect varying levels of psychological, emotional, behavioral, and social adjustment and align with international literature. This study offers a novel contribution by identifying specific adjustment patterns among adolescents in care, providing valuable insights to inform more tailored intervention and prevention strategies aimed at fostering healthier development and well-being in this vulnerable group.
