- The 15-minute city in Porto, Portugal: accessibility for the elderlyPublication . Guerreiro, Maria; Dinis, Maria Alzira Pimenta; Sucena, Sara; Pereira, Madalena Sofia Araujo; Silva, Isabel; Ferreira, Diogo; Silva Moreira, RuiThe concept of the 15-Minute City aims to enhance urban accessibility by ensuring that essential services are within a short walking distance. This study evaluates the accessibility of Porto, Portugal, particularly for the elderly, by assessing urban density, permeability, and walkability, with a specific focus on crossings and ramps. A five-step methodology was employed, including spatial analysis using QGIS and Place Syntax Tool, proximity assessments, and an in-situ survey of crossings and ramps in the CHP. The results indicate that while the city of Porto offers a dense and walkable urban environment, significant accessibility challenges remain due to inadequate ramp distribution. The data collection identified 80 crossings, of which only 60 were listed in OpenStreetMap, highlighting data inconsistencies. Additionally, 18 crossings lacked curb ramps, posing mobility barriers for elderly residents. These findings highlight the need of infrastructure improvements to support inclusive urban mobility. The study also proposes an automated method to enhance ramp data collection for broader applications. Addressing these gaps is crucial for achieving the equity and sustainability goals of the 15-Minute City model, ensuring that aging populations can navigate urban spaces safely and efficiently.

- Adaptation of the Bergen Facebook Addiction Scale for a sample of portuguese populationPublication . Leite, Ângela; Souto, Teresa; e Sousa, Hélder Fernando Pedrosa; de Moura, Andreia; Dinis, Maria Alzira Pimenta; Cunha, Lígia; Lira, Vitor; Vidal, Diogo GuedesThe aim of this study is to adapt a Portuguese version of the original 18 items of the Bergen Facebook Addiction Scale (BFAS), via a translation / back translation process, using Confirmatory Factor Analysis (CFA) in a Portuguese sample. The sample comprised 232 respondents from the general population. The modified BFAS acquires a different factor structure from the original, keeping 4 of the main theoretical elements (subscales) and 10 of the 18 original items. The results indicate that the Portuguese version of the original BFAS presents good psychometric qualities. The statistical techniques used in the study allowed assessing the reliability and validity of the modified BFAS. Nevertheless, further uses of this scale with other samples from the Portuguese population are necessary to confirm the obtained results.
- Adaptation of the phubbing scale and of the generic scale of being phubbed for the portuguese populationPublication . Mendes, Letícia; Silva, Beatriz Reis; Vidal, Diogo Guedes; e Sousa, Hélder Fernando Pedrosa; Dinis, Maria Alzira Pimenta; Leite, ÂngelaExcessive, abusive, or inappropriate use of mobile phones can have a negative effect on interpersonal relationships. This study aims to adapt the Phubbing Scale (PS) and the Generic Scale of Being Phubbed (GSBP) for the Portuguese population, establishing the convergent validity of the instruments with others that assess approximate constructs, such as the Partner Phubbing Scale (PPS) and the Nomophobia Questionnaire (NMP-Q), and investigate the differences and/or relationships between sociodemographic variables, mobile phone usage variables and the PS and the GSBP. This is a cross sectional study, including 641 participants, aged between 18-71 (M=27.91; SD=10.60). The Portuguese version of the PS kept the number of items and factors, however, distributed differently from the original version. The Portuguese version of the GSBP kept the structure proposed by the authors of the original version. The correlations obtained by both scales with other instruments ensured convergent validity. Differences were found in the values of the scales according to some sociodemographic variables and some variables regarding mobile phone use. The findings provide culturally adapted and validated two instruments and are helpful to researchers to assess this phenomenon and intervene in a timely manner.
- Addressing climate change education: relevant contributions from universitiesPublication . Leal Filho, Walter; Sow, Baba Libasse; Perlin, Ana Paula; Mbah, Marcellus Forh; Costa, Cristina Amaro da; Azam, Fardous Mohammad Safiul; Dinis, Maria Alzira PimentaPurpose: This study aims to identify and describe the nature of higher education institutions’ (HEIs) engagement with climate change (CC) education, exploring their contributions to addressing the multifaceted challenges associated with the phenomenon. Design/methodology/approach: By using a dual methodological approach consisting of an expert-driven literature review with supporting cases, the study provides a novel perspective of university involvement in CC education, emphasising theoretical insights and practical applications. Findings: The study asserts that universities contribute significantly to CC education through the development of specialised teaching programmes, innovative research initiatives and the establishment of interdisciplinary collaborations. However, challenges abound, including limited financial resources, institutional inertia and the complexity of integrating CC topics across diverse academic disciplines. By fostering partnerships with external stakeholders, implementing innovative teaching methodologies and strengthening governance frameworks, universities can further enhance the effectiveness and reach of CC education initiatives. Research limitations/implications: While the study offers valuable insights, it acknowledges potential limitations, including the scope of example studies and the specificity of findings to certain institutional contexts, which impedes generalisation. Avenues for further research to understand university contributions to CC education have been advanced. Practical implications: The paper provides practical insights for universities to optimise their engagement in CC education, emphasising the mobilisation of student involvement and the promotion of transdisciplinary approaches, amongst others. Social implications: While emphasising the role of universities in CC education, the study underscores the broader societal impact of informed and engaged HEIs to drive positive change by instilling awareness and promoting sustainable practices. Originality/value: The findings offer original perspectives on the importance of university engagement in CC education and provide practical measures for optimising their contribution to a sustainable future via pedagogical, programme and strategic/whole institutional levels.

- Adverse childhood experiences and delinquent behaviour: predictors and mediating variablesPublication . Martins, Joana; Dinis, Maria Alzira Pimenta; Caridade, Sónia; Sousa, Hélder; De Moura, AndreiaAdverse childhood experiences (ACEs) have been identified as a risk factor for the development of mental health and behavioural outcomes throughout life, including delinquent behaviours. This article focuses on the relationship between ACEs and delinquent behaviour (DB), seeking to identify predictors and mediating variables. Methods: The quantitative study comprised 175 Portuguese adolescents, aged 12 and 17 years of age (M = 14.99, SD = 2.26). Results: ACEs and exposure to traumatic events (ETE) are predictive of DB. Antisocial traits (AT) was found to be mediating the relationship between ACEs and DB, as well as the relation between ETE and DB. Conclusion: The results indicate that it is necessary that professionals in health behaviour field prevent and intervene in ACEs and in ETE, both predictors of DB. The results of this study allow to understand the role of ACEs in DB and its mediating variables, which must be considered to mitigate the harmful impact of ACEs in DB.

- Alexitimia, Psicopatia e Sintomatologia Psicopatológica em estudantes universitários: preditores e mediadores de adição ao álcoolPublication . Andrade, Bruna; Sousa, Hélder Fernando Pedrosa e; Dinis, Maria Alzira Pimenta; Ferros, Lígia; Negreiros, Jorge; Moura, Andreia Paiva deNo presente artigo pretendeu-se encontrar e explorar relações entre psicopatia, alexitimia e sintomatologia psicopatológica na amostra em estudo (estudantes universitários) e a adição química (álcool). Pretendue-se também compreender se a psicopatia, alexitimia e sintomatologia psicopatologica constituem fatores preditores e/ou mediadores da adição ao álcool. A amostra em estudo é constituída por 260 participantes (estudantes universitários). A idade média é de 20.54, ou seja, 21 anos e, varia entre os 18 e os 51 anos. Relativamente ao sexo, 32 (12.5%) são do sexo masculino e 224(87.5%) do sexo feminino (N=258). A psicopatia avaliada através da LSRPS, alexitimia através da TAS-20, e a sintomatologia psicopatológica pelo BSI. A adição ao álcool pelo AUDIT. Os resultados mostraram evidência empírica sobre a relação entre a psicopatia, alexitimia e sintomatologia psicopatológica com a adição ao álcool. Alexitimia e psicopatia não medeiam a relação entre sintomatologia psicopatológica e adição álcool. Além disso, a psicopatia não medeia a relação entre alexitimia e a adição ao álcool.
- An assessment of priorities in handling climate change impacts on infrastructuresPublication . Leal Filho, Walter; Abeldaño Zuñiga, Roberto Ariel; Sierra, Javier; Dinis, Maria Alzira Pimenta; Corazza, Laura; Nagy, Gustavo J.; Aina, Yusuf A.Climate change (CC) will likely significantly impact the world’s infrastructure significantly. Rising temperatures, increased precipitation, and rising sea levels are all likely to stress critical infrastructures (CI). Rising temperatures can lead to infrastructure damage from extreme heat events. This can cause roads and bridges to buckle or crack, leading to costly repairs and potential traffic disruptions. In addition, heat waves can damage vital electrical infrastructure, leading to widespread power outages. In light of this context, this article reports on a study which examined the connections and impacts of CC on infrastructure. The study employed a mixed-method approach, combining bibliometric analysis for the period 1997–2022 with a series of relevant case studies from the five continents to offer insight into the impact of CC on infrastructure. The article fills a research gap in respect of assessments of the extent to which climate change (CC) negative influences the infrastructure, with a special focus on developing countries. It also showcases CI projects and adaptation measures being currently deployed, to address CC. The results show that the current infrastructure is vulnerable to CC. The selected case studies on CI adaptation show that in developing and industrialised countries, there is a perceived need to understand better the connections and potential impacts of CC on critical areas such as transport, settlements, and coastal infrastructure. In order to protect infrastructure from CC impacts, governments need to invest in measures such as flood control, early warning systems, and improved building codes. Additionally, they need to work to reduce greenhouse gas emissions more actively, which are the primary cause of CC.
