- Adaptation and validation of the perceived restorativeness scale (PRS) for the portuguese population: a study on the assessment of the restorative effect of environmentsPublication . Sousa, Cátia; Silva Fernandes, Maria Jacinta; Encarnação, Tiago; Gonçalves, GabrielaThe relationship between natural environments and psychological well-being has gained increasing attention in environmental and health sciences. However, there is still a lack of robust quantitative instruments to assess the restorative potential of different environments. This study aimed to adapt and validate the Portuguese version of the Perceived Restorativeness Scale (PRS), an instrument based on Attention Restoration Theory that evaluates the perceived restorative qualities of environments. In Study 1, exploratory and confirmatory factor analyses were conducted on data from 410 participants. The results supported a refined 20-item version of the scale, comprising four factors—being away, fascination, compatibility, and legibility—with good internal consistency and acceptable model fit. Measurement invariance analysis confirmed configural, metric, and scalar invariance across gender. In Study 2, a separate sample of 212 participants completed the PRS along with additional validated measures: the Sublime Emotion toward Nature Scale (SEN), an aesthetic evaluation of landscapes, and the Positive and Negative Affect Schedule (PANAS). The PRS showed strong convergent and discriminant validity and significantly predicted restorative outcomes. These findings support the psychometric adequacy of the Portuguese PRS and its relevance as a valid tool for assessing perceived restorativeness in both natural and built environments. The scale may inform future research and public policies aimed at designing spaces that promote psychological restoration and mental well-being.
- Applying remote sensing technologies in urban landscapes of the mediterraneanPublication . Pedras, Celestina; Maria Neto Paixão Vazquez Fernandez Martins, Helena; Lança, Rui; Granja Martins, Fernando MiguelThere has been increasing pressure on water resources in cities due to the proliferation of urban green areas. In the Mediterranean climate, only a small part of the plants’ water needs is supplied by rainfall during the winter months. Thus, in Algarve (Portugal) irrigation of the urban landscapes is required almost all year round. The aims of this study were to evaluate the maintenance of the urban landscapes of São Brás de Alportel (Algarve) during a year, based on the characterization of the vegetation of the urban gardens, the climate data, the analysis of the irrigation systems, the calculation of the plants water requirements and the normalized difference vegetation index (NDVI). By crossing all this information, it was possible to understand if the current maintenance level is the most suitable for sustainable irrigated urban landscapes. In most of the gardens, it was possible to establish a relationship between the gross irrigation water requirements and NDVI. In general, the NDVI allowed us to study the urban landscape, through the monthly observation of the differences in the appearance and development of the vegetation.
- Cognitive, affective and behavioural repercussions of perceived quality in tourism vocational education: insights from self-determination theoryPublication . Silva, Rejane Santana da; Quiroga Souki, Gustavo; Oliveira, Alessandro Silva de; Vieira, Luís Sérgio; Dionísio Serra, Manuel AntónioPurpose – This study aimed to investigate the influence of the perceived quality by students regarding their experiences in vocational schools in tourism, hospitality and food service on cognitive and affective responses (satisfaction, self-efficacy expectations and self-regulation strategies of motivation for learning - SRSML) and commitment (behavioural response). Design/methodology/approach – A cross-sectional survey was conducted with 454 students from twelve Turismo de Portugal IP-affiliated schools. The theoretical framework was rooted in Self-Determination Theory (SDT) and PLS-SEM, using ADANCO 2.3 software to test the proposed model. Findings – Perceived quality by students concerning their school experiences are socio-contextual factors that directly influence their satisfaction and self-efficacy expectations (cognitive and affective responses). Satisfaction and self-efficacy expectations positively affected SRSML. Finally, satisfaction and the SRSML positively impacted the students` commitment to schools (behavioural response). Originality/value – This study contributes to academia by comprehensively addressing 16 perceived quality dimensions within vocational education. It aligns with SDT, revealing that socio-contextual factors affect students’ cognitive, affective, and behavioural responses. Additionally, it demonstrates positive relationships between student satisfaction, self-efficacy expectations, SRSML, and students’ commitment to vocational education institutions. This study emphasises the multidimensional nature of perceived quality, urging educational institutions to address tangible and intangible dimensions to develop strategies to provide high-quality experiences, increasing students` satisfaction, self-efficacy expectations, motivation, and commitment.
- Design, environment, energy, and comfort in buildings equipped with a PMV-controlled HVAC systemPublication . Conceição, Eusébio; Conceição, Margarida; Conceição, Maria Inês; Lúcio, Maria Manuela Jacinto do Rosário; Awbi, HazimThis work presents a study about the design, environment, energy, and comfort in buildings equipped with a Predicted Mean Vote (PMV)-controlled HVAC system. The control system, based on the three categories of the international standard ISO 7730 uses the level of thermal comfort instead of the traditional control of the air temperature. In this type of control, using the PMV index, the air temperature (Tair), air relative humidity (RHair), Mean Radiant Temperature (MRT), air velocity (Vair), level of clothing (CL), and level of physical activity (AL) are considered. The initial four parameters are associated with environmental ones, and the last two are associated with personal ones. The simulation is carried out using a simulator of the dynamic thermal response of buildings and the thermophysiology of the occupants. The simulator considers energy and mass balance integral equations, based on the building’s design. This equation system is generated by the simulator. In this study, three cases are performed: Categories A, B, and C. According to the results obtained, it is possible to verify that it takes some time to achieve acceptable comfort conditions when the HVAC system is connected. However, after the conditions are achieved, the system guarantees acceptable conditions during the occupancy time. Category A provides higher levels of energy consumption than Categories B and C.
- Digital technologies and public policies applied to green citiesPublication . Sousa, Maria JoséDigital technologies and public policies are fundamental for cities in defining their urban greening strategies, and the main goal of this research is to identify the applied digital technologies and the public policy dimensions implemented at the national level by the member states to promote urban greening in the literature and official documents. The methodology used is a systematic literature review (based on international studies), a Delphi study with experts, and a policy analysis, aiming to understand how the Portuguese government has implemented policies and identify the main technologies applied to urban greening. The main findings regard (i) the focus on the interaction between actors in policymaking; (ii) interpretive approaches used to examine the application of technologies in urban greening problems; and (iii) how policies reflect the social construction of ‘problems’. The research focuses on how policy analysis provides a powerful tool that can be used to understand the technologies, actions, interests, and political contexts underpinning policy decisions. The main lessons learned from this research are that urban greening can benefit urban centers together with the non-urban environment on which they have a functional impact, such as agricultural hinterland areas, forest spaces around the cities, and the rural–urban interfaces. Initiatives for urban greening are designed to enhance cross-border coordination, complementarities, flexibility, productivity, and access to the main international markets and territories.
- Empowering maritime spatial planning and marine conservation efforts through digital engagement: the role of online platformsPublication . Gutierrez, Débora; Calado, Helena; Toor, Femke van; Moreira, Mariana; Paramio, Maria Luz; Martins, Francisco; Santos, Natali; Melo, Neuza; Newton, AliceThis study addresses the performance of digital platforms in enhancing ocean governance by improving communication and collaboration among stakeholders. It analyses several platforms based on their collaborative initiatives, digital tools, and ability to function as networks of knowledge. The findings show that these platforms bridge gaps between regional, national, and non-governmental organisations, promoting informed decision making. Their online presence enhances transparency and engagement, especially postCOVID-19. This study highlights the need for hybrid platforms combining informative and interactive elements to better serve both experts and the public. From this analysis, some recommendations are drawn to provide rules and design for the cooperation and co-design of a platform to foster better communication, collaboration, and sustainable ocean management practices.

- Factors influencing the choice of the Algarve region as a tourist destination: does season matter?Publication . Barreira, Ana Paula; Cesário, MarisaThe dissimilar ways in which tourists assess the attributes of a tourism destination in different seasons is an issue scarcely addressed in the literature. Here, we show that the characteristics of a tourism destination (the Algarve region, Portugal) are rated differently in peak (summer) and off‐peak (autumn/winter) seasons. Nationality is decisive in explaining the different assessments between seasons of the factors that group subsets of 17 attributes of the tourism destination. In general, the factors that are rated higher by domestic tourists during the summer are the same as those that are rated higher by foreign tourists in the autumn/winter.
- From destination attributes to tourist satisfaction: novelty-seeking as a bridge between liminality and place attachmentPublication . Lança, Milene; Nobre Pereira, Luis; Silva, joão; Andraz, Jorge; Cunha Sousa Nunes, Rui JoséThis study analyses how destination attributes influence tourist satisfaction via perceived quality, price, and safety, and how these relationships differ by novelty-seeking orientation. Framed at the intersection of liminality and place attachment, novelty-seeking is conceptualised as the behavioural mechanism linking extraordinary experiences to emotional bonds with place, offering the first empirical integration of these frameworks in tourism research. Using data from 1,488 tourists visiting the Algarve (Portugal) in 2022–2023 and Partial Least Squares Multigroup Analysis (PLS-MGA), the results show that for conservative tourists, destination attributes enhance perceived quality, lower perceived prices and safety concerns, and increase satisfaction. For adventurous tourists, satisfaction is driven mainly by perceived price and is negatively affected by in situ safety concerns, indicating that novelty-seekers do not uniformly discount risk. The findings highlight how novelty-seeking conditions cognitive pathways to satisfaction and inform market segmentation strategies aligned with distinct motivational orientations.
- HVAC systems applied in university buildings with control based on PMV and aPMV indexesPublication . Conceição, Eusébio; Sousa, António F. M.; Gomes, João; Ruano, AntonioIn this work, HVAC (Heating, Ventilation and Air Conditioning) systems applied in university buildings with control based on PMV (Predicted Mean Vote) and aPMV (adaptive Predicted Mean Vote) indexes are discussed. The building’s thermal behavior with complex topology, in transient thermal conditions, for summer and winter conditions is simulated by software. The university building is divided into 124 spaces, on two levels with an area of 5931 m2 , and is composed of 201 transparent surfaces and 1740 opaque surfaces. There are 86 compartments equipped with HVAC systems. The simulation considers the actual occupation and ventilation cycles, the external environmental variables, the internal HVAC system and the occupants’ and building’s characteristics. In this work, a new HVAC control system, designed to simultaneously obtain better occupants’ thermal comfort levels according to category C of ISO 7730 with less energy consumption, is presented. This new HVAC system with aPMV index control is numerically implemented, and its performance is compared with the performance of the same HVAC system with the usual PMV index control. Both HVAC control systems turn on only when the PMV index or the aPMV index reaches values below −0.7, in winter conditions, and when the PMV index or the aPMV index reaches values above +0.7, in summer conditions. In accordance with the results obtained, the HVAC system guarantees negative PMV and aPMV indexes in winter conditions and positive PMV and aPMV indexes in summer conditions. The energy consumption level is higher in winter conditions than in summer conditions for compartments with shading, and it is lower in winter conditions than in summer conditions for compartments exposed to direct solar radiation. The consumption level is higher using the PMV control than with the aPMV control. Air temperature, in accordance with Portuguese standards, is higher than 20 ◦C in winter conditions and lower than 27 ◦C in summer conditions. In Mediterranean climates, the HVAC systems with aPMV control provide better occupants’ thermal comfort levels and less energy consumption than the HVAC system with PMV control.
