Bridging the gap in teacher SEL training: Designing and piloting an online SEL intervention with and for teachers
Get PDFThis study depicts the development of an online SEL intervention for Portuguese elementary-school teachers (A+), through an exploratory sequential design. First, to ensure the relevance and applicability of the A+ , ten focus group were conducted with 66 elementary-school teachers (90.9 % female, Mage=45.56 years, SDage=5.57). Results indicated strong interest and perceived relevance among teachers regarding SEL interventions. Based on Phase 1’s identified needs and the SEL theoretical framework, a pilot version of the A+ was designed. To evaluate the efficacy and validity of the A+ pilot version, a pre-posttest mixed-methods design with 21 teachers (90.5 % female, Mage=49.00 years, SDage=6.44) was conducted. Data were collected through self-report questionnaires and analyzed using Robust Linear Mixed Models. Results suggested positive effects of the A+ program on teachers’ positive affect, responsible decision-making skills, and well-being. Additionally, teachers expressed high levels of interest and satisfaction with the proposed content and procedures. Despite its limitations, this study presents promising indicators of the A+ program’s potential effectiveness and suitability.info:eu-repo/semantics/publishedVersio
The new fado of the students: Proximity between utopia and architecture education
Get PDFAcademia is in crisis, and the reflection on its repositioning highlights the urgency of a paradigm shift. Today, the unexpected (re)emergence of countercultural practices in Portugal raises doubts about whether Architecture education is truly fulfilling its mission. This chapter examines ancient processes of reflection and action on the city and society, aiming to understand their influence. It recalls the importance of utopian thinking as a driving force for change and the practice of radical pedagogies as a response to new social desires. In an attempt to recognize the power of these mechanisms—utopian thinking and radical pedagogies in Architecture education—historical events that shaped both Portugal and the world are described here through the connections between concepts such as revolution, people, and radical thinking, and agents like schools, students, and education, all of which share utopia as the central figure in the narrative of social change in Portugal. In conclusion, contemporary utopianism, though real and teachable, remains distant from the academic curriculum. The absence of this methodology and these practices in Portugal makes this a unique issue in Portuguese Architecture education, highlighting the urgency of their revival.info:eu-repo/semantics/publishedVersio
Mongolia mining: Licensed tenure or commons grabbing
Get PDFKey to pastoralism, communal land in Mongolia is buffeted by expanding resource extraction with limited government oversight. Herders continue seasonal movement according to environmental conditions, particularly pasture quality, drought and extreme cold. Recently mobility and pastoral commons have been affected by the increase in mineral licenses and subsequent mine exclusionary zones. The process is often framed by development discourses and claims of adhering to global standards such as the Sustainable Development Goals (SDGs). Using remote sensing and interviews our study examined mining impact on pastures and the role of global initiatives in addressing herder concerns. The study documented significant mining expansion at three mega-mines, a process that removes land from what was the community commons. Amongst herders there was limited awareness of the SDGs or relevance to their daily lives. The SDG agenda, embraced in the capital, was not considered beneficial to herders. The rural challenge is to maintain open pasture access with the development of mining. Social and political engagement is essential for herders’ continued viability in the country.info:eu-repo/semantics/publishedVersio
Entrepreneurial passion: A key driver of social innovations for tourism firms
Get PDFSmall and medium tourism enterprises (SMTEs) play a vital role in the sustainability and innovation of tourism destinations. Although their role in the sustainability of destinations has received much attention, research focusing on the antecedents of their social innovation practices remains limited. Drawing on theories on entrepreneurship and social innovation, this study contributes to the body knowledge through an empirical analysis of the factors that drive the social innovations of tourism entrepreneurs. For this purpose, a mixed method approach is conducted which includes an e-survey of tourism entrepreneurs (analysed using PLS-SEM, NCA and IPMA) followed by in-depth interviews to gain additional insights. The results showed that 68 % of the SMTEs pursue social development objectives, and 44 % seek opportunities to improve the social conditions of the community in which the firm operates. The results also reveal that entrepreneurial self-efficacy, community attachment and entrepreneurial passion positively influence social innovations, however, entrepreneurial passion is a ‘necessary condition’ for achieving social innovation outcomes. Research also found that ‘opportunity perception’ has an indirect effect on social innovations that is mediated by entrepreneurial self-efficacy. The results provide important insights for the development of social innovation in the context of tourism entrepreneurs, with practical implications for local governments and destination authorities in supporting entrepreneurship and sustainability.info:eu-repo/semantics/acceptedVersio

Neural hierarchical interpolation time series for reservoir level multi-horizon forecasting in hydroelectric power plants
Get PDFEnergy planning in systems heavily influenced by hydroelectric power is based on assessing the availability of water in the future. In Brazil, based on the soil moisture active passive, the National Electricity System Operator defines electricity dispatch concerning a stochastic optimization problem. Currently, machine learning models are an alternative for improving forecasts, and could be a promising solution for predicting reservoir levels at hydroelectric dams. In this paper, neural hierarchical interpolation for time series (NHITS) is applied to improve forecasts and thus help decision-making in the management of electric power systems. The NHITS model achieved a root mean square error of 4.64×10−4 for a 1-hour forecast horizon, and 1.03×10−3 for a 10-hour forecast horizon, being superior to multilayer perceptron (MLP) neural network, long short-term memory (LSTM), convolutional neural network with long shortterm memory (CNN-LSTM), recurrent neural network (RNN), Dilated RNN, temporal convolutional neural (TCN), neural basis expansion analysis for interpretable time series forecasting (N-BEATS), and deep nonparametric time series forecaster (DeepNPTS) deep learning approaches.info:eu-repo/semantics/publishedVersio
The effect of Artificial Intelligence technology on carbon emissions
Get PDFAs the new wave of technological revolution and industrial transformation advances, artificial intelligence technology plays a crucial role in addressing climate change and empowering the achievement of “peak carbon emissions” and “carbon neutrality” goals.
This study conducts a systematic review of four key variables: AI orientation, green technology innovation, environmental regulation, and carbon emissions. Drawing upon strategic management theory, technological innovation theory, and low-carbon economic theory, it proposes research hypotheses and constructs corresponding theoretical models. Descriptive statistics and correlation analysis are employed to validate the relationships among these variables, yielding significant empirical findings. Firstly, both enterprise artificial intelligence orientation and green technology innovation exert substantial suppressive effects on carbon emissions. Secondly, AI orientation effectively stimulates the enhancement of green technology innovation. Thirdly, AI orientation impacts carbon emissions through its influence on green technology innovation. Furthermore, environmental regulation is identified as a positive moderator of the relationship between green technology innovation and carbon emissions.
In conclusion, based on the empirical analysis, this study identifies theoretical contributions and managerial insights while outlining research limitations and future directions. In light of the “dual carbon” objectives, prioritizing green and low-carbon development is crucial. Developing AI technologies aligned with these goals and guiding their application in carbon emission reduction are essential strategies. Additionally, tailoring development policies to the unique contexts of different regions is imperative for effective implementation.À medida que a nova onda de revolução tecnológica e transformação industrial avança, a tecnologia de inteligência artificial desempenha um papel crucial no enfrentamento das mudanças climáticas e empoderamento da consecução dos objetivos de "pico de emissões de carbono" e "neutralidade de carbono".
Este estudo realiza uma revisão sistemática de quatro variáveis-chave: orientação para IA, inovação em tecnologia verde, regulação ambiental e emissões de carbono. Baseando-se na teoria da gestão estratégica, teoria da inovação tecnológica e teoria econômica de baixo carbono, propõe hipóteses de pesquisa e constrói modelos teóricos correspondentes. A estatística descritiva e a análise de correlação são empregadas para validar as relações entre essas variáveis, produzindo achados empíricos significativos. Em primeiro lugar, tanto a orientação de inteligência artificial empresarial quanto a inovação em tecnologia verde exercem efeitos supressores substanciais sobre as emissões de carbono. Em segundo lugar, a orientação da IA estimula efetivamente o aprimoramento da inovação tecnológica verde. Em terceiro lugar, a orientação da IA impacta as emissões de carbono através de sua influência na inovação tecnológica verde. Além disso, a regulação ambiental é identificada como um moderador positivo da relação entre inovação tecnológica verde e emissões de carbono.
Em conclusão, com base na análise empírica, este estudo identifica contribuições teóricas e insights gerenciais, delineando limitações de pesquisa e direções futuras. À luz dos objetivos de "duplo carbono", priorizar o desenvolvimento verde e baixo carbono é crucial. Desenvolver tecnologias de IA alinhadas a esses objetivos e orientar sua aplicação na redução de emissões de carbono são estratégias essenciais. Além disso, adaptar as políticas de desenvolvimento aos contextos únicos das diferentes regiões é imperativo para uma implementação eficaz
Producción de recursos educativos para la educación mediática en la escuela: Percepciones y necesidades de los profesores
Get PDFA relevância da educação mediática tem sido crescentemente reconhecida no contexto internacional e também em Portugal. Às crianças e aos jovens é atribuída particular atenção, o que faz recair sobre a escola e os professores enorme responsabilidade, no sentido de contribuírem, desde cedo, para a formação de cidadãos informados, comunicadores eficazes e participantes ativos na cultura digital. A investigação realizada teve como principal objetivo conhecer as perceções dos professores do ensino básico e secundário sobre a educação mediática e sobre o seu papel e o da escola na promoção da literacia digital e mediática dos alunos, conhecer a sua formação e necessidades e, desta forma, reunir informação útil para orientar a elaboração de recursos educativos. Seguindo uma metodologia não experimental e descritiva, com base em dados obtidos a partir de um questionário online, elaborado pela equipa de investigadores, foi possível concluir que os professores atribuem grande relevância à educação mediática, reconhecem a importância da escola e de si próprios na formação dos alunos, mas revelam também uma formação deficitária neste domínio. Com base nestes resultados, foram elaborados dois recursos educativos, um livro e uma aplicação móvel, pensados para apoiar os professores na resposta ao desafio da implementação da educação mediática na escola.info:eu-repo/semantics/publishedVersio
Decommissioned Places of Worship: A project in Salerno
Get PDFDecommissioned ecclesiastical heritage represents a growing challenge for historic European cities, where the abandonment and disuse of churches reflect profound cultural and demographic shifts. These buildings, once centres of community life and guardians of historical, artistic, and identity significance, now risk decay, potentially undermining the surrounding urban fabric. Repurposing disused churches offers significant opportunities for urban regeneration, with interventions aimed at integrating new functions compatible with the original identity of these sacred spaces. This study exemplifies an integrated reuse strategy designed to create a network of ecological and accessible public spaces, connecting decommissioned churches and enhancing their historical role within the city of Salerno in southern Italy.publicad
Are morally courageous leaders more effective?
Get PDFDetecting, interpreting, assuming responsibility, and being driven to act upon situations with potential ethical implications requires morally courageous leaders to be continuously ‘tuned’ to the environment. We argue that this ‘tuning’ facilitates leader respect for employees and greater receptiveness to their inputs, and that it is through these mechanisms that leader moral courage is positively related to leader effectiveness. In a multi-source study involving 102 team leaders (assessed by peers, subordinates, and supervisors), we found that leaders with higher levels of moral courage convey greater respect for team members and are more receptive to relational transparency from them, and that such respect and receptiveness enhance leader effectiveness. We also hypothesized and found that leaders who overestimate their moral courage (i.e., who self-describe as being morally courageous while others perceive them as not being so) are particularly less respectful toward team members, and thus are less effective.info:eu-repo/semantics/publishedVersio
