- Análise crítica do discurso: proposta didática de abordagem com estudantes do ensino superiorPublication . Macário, Maria João; Silva, Ana IsabelA análise crítica dos discursos mediatizados permite compreender os textos para além dos próprios textos, através da análise das estratégias discursivas e da construção de significados dos atores sociais. A compreensão sobre os contextos sociais no funcionamento (social) dos discursos justifica-se no ensino da Pragmática com estudantes do ensino superior. Tal é o caso dos alunos que frequentam cursos de Comunicação Social, na medida em que a transformação dos discursos para serem difundidos através dos meios de comunicação de massas (quer sejam os tradicionais ou os novos média) será certamente objeto de trabalho nas suas práticas profissionais futuras. Exemplificando como o ensino da Pragmática poderá ser mobilizado para a vida profissional destes estudantes, este artigo centra-se nos resultados de uma proposta didática de análise crítica de discursos mediatizados por estudantes finalistas de Comunicação Social. Esta investigação de abordagem qualitativa foi desenvolvida no ano letivo de 2021/2022 e envolveu uma análise de conteúdo a partir das práticas de análise discursiva dos estudantes, que dispunham de um guião didático para apoiar o seu trabalho de análise. Este estudo de caso, envolvendo 60 participantes, revelou-nos a oportunidade desta proposta para os estudantes compreenderem os discursos como práticas sociais, que resultam e dão origem (simultaneamente) a fenómenos sociais, que importa conhecer. Ao mesmo tempo, esta proposta permitiu contribuir para o desenvolvimento de capacidades analítico-críticas e reflexivo-interpretativas, importantes para a ação profissional futura destes participantes.
- Cultural Indicators as a Tool for Assessing Sustainable Development in the Alto Douro Wine RegionPublication . Mota, Miguel Ângelo Sousa Dias Ferreira da; Silva, Andreia; Vieira, Isabel; Fernandes, Didiana; Rodrigues, AnaCulture has been particularly emphasised over the years in discussions about sustainable development, being considered as one of its fundamental pillars alongside the environmental, economic, and social dimensions. The measurement of the impact of culture on sustainable development is still very incipient, so the purpose of this study is to study how culture can influence the sustainable development of the Alto Douro Wine Region, using the tool designed by UNESCO, the UNESCO Thematic Indicators for Culture in the 2030 Agenda. The methodology adopted was based on the collection of secondary, qualitative, and quantitative data. It was intended to propose a specific methodological tool, by selecting a set of 6 indicators, among the 22 proposed by the UNESCO tool, which were considered the most relevant considering the effort and cost of obtaining them. The results obtained revealed that there was a positive evolution of the cultural sector in the territory, after its integration by UNESCO in the World Heritage List, capable of promoting

- Strategic Management of Cultural Projects—CIM DOURO TrainingPublication . Mota, Miguel; Carvalho, Ana; Fonseca, SMSR; Guia, AnaConsidering the implementation of new forms of strategic management in organizations and the development of competencies, training in the area of cultural heritage has become a priority in the CIM (Inter-municipal Communities). The SMART methodologies and Start Up tools allow creating a commitment to the organization in a holistic vision, which is essential for local development. The 19 municipalities of the Douro region, part of the territorial structure of Intermunicipalities Community (CIMDOURO) have invested in the training of their employees with the aim of equipping them for the new technological realities in the strategic management of cultural projects. This training is based on simplification of processes and improvement of procedures, using digital platforms. The e-learning training took place from January to June 2023. Through online training, our goal is to identify the needs of organizations, particularly municipalities, and their territorial identities, developing strategies for managing cultural projects and creating their own action plans. Currently, employees of various municipalities have the task of developing action plans to study or explore new locations or create networks based on the cultural heritage of these places, promoting sustainability and diversity. This study aims to identify what strategic management of cultural projects is and the need for various territories to use different types of action plans to improve their performance. The case study is limited to the training of employees in the 19 municipalities of the Douro region. The case study was limited to the training of employees in the 19 municipalities of the Douro region. To achieve this objective, a non-probabilistic convenience sample of 16 employees was directly involved, representing various municipalities working in the field of heritage and culture.
- Motivations of Youth Tourism: The Case of University Students in the Porto and North RegionPublication . Soeiro De Carvalho, Ana Branca; Guia, Ana; Duarte, Filipe A P; Flores, Ventura Enrique Mota; Fonseca, Susana Maria Salgueiro Rebelo daTourism nowadays allows for the development and enhancement of many places and countries, leading to improvements in economic, social, cultural, and environmental aspects. It is considered to provide unique experiences to both tourists and the local population through the interaction of different cultures. With various tourism products available, it is essential to identify the motivations and attributes that tourists, especially young tourists, seek and possess regarding a destination. Therefore, we aim to identify and understand the profile and motivations of young tourists/visitors, particularly university students. The World Tourism Organization (WTO) classifies motivations for tourism into two main categories: the first is called Rational Type, which includes concepts such as trust, security, savings, tradition, and modernism. The other is called Affective Type, encompassing curiosity, novelty, sympathy, freedom, and friendship. Currently, young people travel to visit friends and family, for studying or exploring new places, and for the cultural heritage of the destinations. Regardless of the various reasons presented, cultural motivations (such as visiting historical monuments) and motivations to explore new places stand out in most of their visits. The present study aims to identify the profile of youth tourism in Portugal, specifically focusing on young individuals attending higher education, who engage in cultural tourism based on their motivations, behaviours, activities, travel data, and accommodation choices. To achieve this objective, a non-probabilistic convenience sample was used, and a questionnaire survey was developed, resulting in 94 completed questionnaires within the time frame defined between October 1 and December 31, 2022.
- Residents’ Perceptions of Sustainable Tourism Development in an Emerging Destination: A Factor-Cluster ApproachPublication . Mota, Miguel Ângelo Sousa Dias Ferreira da; Vieira, Isabel; Rodrigues, Ana; Alén, ElisaDespite extensive research into the residents’ perceptions of sustainable tourism development (STD) over the past few decades, there has been little exploration of emerging destinations in low-density regions. This study uses a bidirectional analysis to segment the residents of a historic town in the north of Portugal (Lamego), which is part of the Douro World Heritage delimitation. This study applies a factor-cluster analysis to a sample of 250 residents of this historic town on their perceptions of community involvement, local government management of tourism (LGMT), perceived risk, community attachment, tourism impacts, economic dependence, and support for STD. Residents were clustered according to their community involvement and their perceptions of the effectiveness of LGMT. The findings reveal that three clusters of residents were identified: ‘Advocates,’ ‘Disinterested,’ and ‘Conditional supporters.’ The findings support that these groups exhibit dissimilar levels of community attachment, perceived tourism benefits, economic dependence, and support for STD. The three clusters had no significant differences regarding perceived costs and perceived risk. Furthermore, there are significant differences between the three clusters based on almost every socio-demographic variable used. The results reinforce the importance of analyzing the residents’ perceptions in the planning and decision-making policies for STD. Contributions of these findings to the body of knowledge and managerial implications are discussed.

- Identification, readiness and potencial of technology domains for decarbonisation and role of the eletric power systemPublication . Duarte, António Francisco Costa; Costa, Paulo Moisés Almeida da; Tomé, Paulo Rogério PerfeitoThe intensive use of fossil fuels in recent years has led to a significant increase in carbon dioxide (CO2) levels in the atmosphere, contributing to global warming and its harmful effects on the climate. Global warming has become one of humanity’s most urgent challenges. As a result, there is increasing pressure to reduce carbon emissions and take measures to limit the extent of climate change and its severe consequences. This dissertation, developed under the research project “Sustainable Transformative Transitions - reconcile the acceleration of low carbon transitions with system transformations” – (PTDC/GES-AMB/0934/2020), funded by the Foundation for Science and Technology, focuses on the decarbonisation theme. Its content can be subdivided into two main parts. In the first part, a methodology based on two text-mining tools was developed and applied to identify the domains of innovative decarbonisation technologies and instruments that have received significant attention from the scientific community in recent years. To achieve this, documents from databases of scientific publications (Scopus and Web of Science), research projects (Cordis), and patents (Patstat) were examined. Computational software was developed and used to process the outputs of the text-mining software and obtain a relevant set of terms related to decarbonisation technologies/instruments. Those terms were then consolidated based on their characteristics to establish a set of 41 domains of technology/instruments that emerged as the most relevant to support the decarbonisation process. Analyses were carried out to assess the significance of these domains in scientific production by examining their relevance and occurrence, both in absolute and relative terms. The readiness of the domains was assessed by calculating the average technology readiness level (TRL) for a specific set of innovative technologies associated with each domain. This process was supported by information from a database provided by the International Energy Agency, which contained data on 368 distinct technology designs and components related to achieving net-zero emissions. The technologies of that database were categorised into specific domains based on their unique characteristics. The domains were then intersected with six literature-derived decarbonisation pathways (defined elsewhere). This analysis revealed that twelve domains emerged as the more crucial in supporting these pathways. In addition, the risk levels for each pathway were determined based on the average Technology Readiness Level (TRL) and relevance-occurrence rank ratios. Furthermore, the potential for decarbonisation of each pathway was assessed using information from the Intergovernmental Panel on Climate Change (IPCC) on the potential for reducing net carbon dioxide emissions (CO2) by 2030. The “Electrification of uses” pathway has emerged as the most promising for decarbonisation, demonstrating the highest readiness and average potential for CO2 emissions reduction and a low-risk value. Furthermore, the “Decarbonisation of electricity” pathway ranks as the fourth most promising option. Consequently, the electrical sector plays a crucial role in achieving decarbonisation goals. Based on these findings, the second part of this work concentrates on developing and applying a model to forecast avoided CO2 emissions for the Portuguese power system until 2050. The model relies on predictions from reliable documents regarding electricity consumption and renewable electricity generation. Hence, four main scenarios were formulated to incorporate electricity consumption and production forecasts. Furthermore, these four scenarios were further categorised to include sub-scenarios related to different charging options for electric vehicles. It is essential to mention that these charging alternatives can significantly impact consumption patterns. The study also examined the effects on emissions due to incorporating storage systems into the electrical system. Additionally, it investigated how the distribution of renewable electricity production and storage systems across different networks within the electrical system influences emissions. The results indicate that, in the base case study, significant values of avoided emissions can be expected from 2023 onwards. Depending on the scenario, the estimated avoided emissions for the 2023-2050 period ranges from 214.2 MtonCO2 (low increase in electricity consumption and conservative growth in non-conventional generation scenario) to 266.5 MtonCO2 (high increase in electricity consumption and ambitious increase in non-conventional generation scenario). The change in the consumption pattern due to the concentration of electric vehicle charging in specific periods (peak or night empty hours) revealed a reduction in the value of avoided emissions, which, in the most unfavourable scenario (represented by a high increase in electricity consumption and ambitious increase in non-conventional generation scenario), reaches 90.4% of the value obtained for the base scenario. Integrating storage systems in the electric networks can potentially enhance the value of avoided emissions. The magnitude of this potential depends on various factors, including the specific scenario considered (in terms of consumption and generation), the indirect emissions associated with storage system manufacturing, and the changes in the load profile due to EV charging. Moreover, the proper planning for storage capacity installation over the years and its location assumes a significant relevance on the value of avoided emissions, namely when considering the indirect emissions from manufacturing the storage systems. The results highlight that storage systems can increase the expected avoided emissions by up to 32.4%, depending on the scenario. Furthermore, the results show that the distribution of the non-conventional generation across various networks directly impacts the expected avoided emissions.
- Conceções dos alunos e dos professores do 2.º Ciclo do Ensino Básico sobre o desenvolvimento de atividades práticas investigativas em Ciências NaturaisPublication . Tenreiro, José Francisco Baltazar; Novais, AnabelaO presente Relatório Final de Estágio intitulado Conceções dos alunos e dos professores do 2.º Ciclo do Ensino Básico sobre o desenvolvimento de atividades práticas investigativas em Ciências Naturais foi realizado no âmbito do Mestrado em Ensino do 1.º Ciclo do Ensino Básico e de Matemática e Ciências Naturais no 2.º Ciclo do Ensino Básico. A nível estrutural, este relatório, encontra-se dividido em duas partes: a primeira abrange uma reflexão crítica acerca das práticas pedagógicas desenvolvidas em contexto de estágio no âmbito da Prática de Ensino Supervisionada no 1.º Ciclo do Ensino Básico e em Matemática e Ciências Naturais no 2.º CEB; a segunda parte contempla um trabalho de investigação que pretende perceber quais as conceções, tanto dos alunos como dos professores do 2.º Ciclo do Ensino Básico, sobre o desenvolvimento de atividades práticas investigativas na área disciplinar de Ciências Naturais. Quanto à metodologia, esta investigação empírica aglomerou-se numa investigação de carácter qualitativo e, para tal, recorreu-se à conceção e implementação de entrevistas, quer para professores como para alunos do 2.º Ciclo do Ensino Básico, com vista a dar resposta à questão-problema: “Quais as perspetivas dos alunos e dos professores do 2.º Ciclo do Ensino Básico sobre a importância das atividades práticas investigativas em Ciências Naturais?”. Os objetivos desta investigação são: identificar as conceções dos alunos sobre as atividades práticas investigativas; identificar as conceções dos professores sobre as atividades práticas investigativas; comparar as perspetivas dos alunos e dos professores face às atividades práticas investigativas; percecionar a relevância das atividades práticas investigativas no ensino das Ciências Naturais; verificar as razões subjacentes à frequência do uso das atividades práticas investigativas em sala de aula. Através deste estudo podemos constatar que as conceções dos professores e dos alunos inquiridos sobre as atividades práticas investigativas são convergentes no sentido em que ambos afirmam que são uma mais-valia quando desenvolvidas nas aulas de Ciências Naturais. Também percebemos que, segundo os indagados, as atividades práticas investigativas são de enorme relevância no ensino das Ciências Naturais, uma vez que potenciam a construção de múltiplas aprendizagens e podem ser mote para que os alunos se sintam mais motivados, pois há em geral um gosto em realizar este tipo de atividades. Ainda podemos retirar deste estudo que as atividades práticas investigativas estão longe de ser implementadas com a regularidade desejada, porque existem diversos fatores condicionantes, derivados da falta de investimento na educação, como é o caso da inexistência de espaços adequados para o seu desenvolvimento para todas as turmas, como por exemplo de laboratórios, e da falta de recursos
