- Identificação de manchas de óleo no mar através da deteção remotaPublication . Ruggeri, Janaina de Paula; Fernandez, Helena; Martins, FernandoAo longo dos anos, a exploração de reservas de petróleo em plataformas continentais em águas mais profundas tem aumentado. Como consequência o transporte do petróleo bruto e dos seus derivados por navios e oleodutos tem tido também um crescimento, o que acarreta um risco de derrame provocando impactos negativos no ambiente e na população das regiões afetadas. Estes efeitos merecem mais atenção quando ocorrem em áreas de reserva natural e em zonas balneares. Em virtude das limitações de técnicas convencionais de fiscalização e monitorização da poluição do mar, a Deteção Remota junto com as imagens de satélites são utilizadas para identificação de manchas de óleo sobre a superfície do mar. Por vezes essa identificação torna-se difícil, devido à existência de outros tipos de manchas escuras que não são de óleo, chamadas de falsos alvos. Por isso, é indispensável a aplicação de técnicas de Deteção Remota para discriminar estas manchas. O objeto de estudo foi um acidente ligado a um derrame de óleo ocorrido em 2019, na região litorânea do nordeste do Brasil, onde o óleo atingiu mais de 130 cidades. O estudo foi desenvolvido a partir da aquisição, processamento e análise de imagens de RADAR do satélite Sentinel- 1 e aplicando as técnicas de Deteção Remota com ferramentas automáticas e semiautomáticas para extração da mancha de óleo. Propõe-se neste trabalho de investigação identificar manchas de óleo, distinguir estas em face de outras manchas escuras resultantes de fenómenos naturais ou outros.
- The customer experience at the destination and behavioural intentions: exploring the role of tourists´ emotionsPublication . Piedade, David Alberto Encarnação; Guerreiro, Manuela; Valle, Patrícia Oom doCustomer experience, and its effects on tourism development, has been the focus of many researchers over recent decades. The continuous demand to increase customer experience levels has been the driving factor for businesses and marketing practitioners to understand how to implement added value to their regions as to obtain sustainable growth and competitive advantage. This challenge has led to researchers exploring the critical post-visit stage of the tourist visit, particularly focusing on the effect of emotions on customer experience. The experience of the visit has a direct effect on tourist’s emotions, and a successful impact at this stage leads not only to tourist loyalty, but also in tourist recommendation of the destination. The primary goal of this study was to address whether customer experience had a positive effect on loyalty, and on positive and negative emotions. Afterwards, we aimed to determine whether these positive and negative emotions themselves had an effect on tourist loyalty. A conceptual model was created to understand the correlations between four latent variables: touristic experience, positive emotions, negative emotions, and destination loyalty. The model was tested through by questionnaire data immediately retrieved post-experience from tourists in the Algarve, between 15th July and 15th September 2021 under the TurExperience project. The data was then analysed under descriptive statistics and utilized to validate the relationships between the constructs proposed in the conceptual model. All hypotheses were supported and validated, indicating that customer experience directly affects tourist’s loyalty at the destination, the Algarve. These results also show that positive and negative emotions with customer experience strongly influence tourist loyalty. Our findings highlight the importance to consider not only customer experience as a valuable tool in creating customer experiences at the tourism level, but also the role of positive emotions in creating experiences by introducing positive emotional stimuli to create memorability, leading to the sharing of these experiences and tourist retention.
- Mediterranean Diet: a multidisciplinary approach to develop a new territorial strategy.Publication . de Freitas, Ana; Dias Azinheira Rebelo Braz, Nídia Maria; BERNARDES, João Pedro; Cruz, Ana Lúcia; Quintas, Célia; Rodrigues Gonçalves, Alexandra; Romano, Anabela; Palma Mateus, MariaMediterranean Diet (MD) integrates territorial diversities, economic and lifestyle changes. These characteristics represent an enormous potential, for a sustainable food pattern and healthy lifestyles, biodiversity and to valorisation of local products. In 2013 Portugal joined the UNESCO MD application for Intangible Cultural Heritage. The University of Algarve, in a partnership with the Competence Centre for the Mediterranean Diet, 4 Regional Agriculture Directorates of mainland Portugal, Tavira City Council (Representative Community) and the Higher Education Institutions’ Network for MD Safe-guard, developed a set of activities with the aim of strengthening the national strategy for MD promotion and safeguard. The activities aimed to raise awareness of the MD characteristics in each territory and to enable effective articulation within the main stakeholders, in a quadruple helix – Agriculture, Health, Heritage and Tour-ism. It was possible to gather a wide range of actors with responsibility in preservation and promotion of MD in each Region. The created working groups are developing further work leading to a safeguard strategy for MD in each Region and the set-up of Regional Commissions for MD (CRDMs). Results point out the relevance of geographical indications (GI) registration of regional characteristic products as a key factor for MD safeguard.
