- Coccolithophores as potential marine resource for sustainable aquaculturePublication . Vicente, Bernardo; Santos, Tamára; São João, Ricardo; Rodrigues, Luísa; Pereira, Hugo; Varela, João; Tenreiro, AnaCoccolithus braarudii (holococcolith) and Emiliana huxleyi (heterococcolith) were isolated from Portuguese coastal waters and domesticated under laboratory conditions with the objective of providing strains with high potential for the production of high value products for aquaculture and biotechnology. The growth patterns and photophysiology of the two species were investigated under controlled conditions, (19±1°C, 12:12 Light: Dark, 115 µmol photons m-2 s-1) using pulse amplitude modulated fluorometry (PAM), and the different growth phases characterized by flow cytometry (cell size, complexity, chlorophyll a autofluorescence and lipid content). The biochemical and nutritional profile of the studied species was assessed by elemental analyses, gravimetric quantification of total lipids and the fatty acid profile determined by gas chromatography coupled with mass spectrometry. The growth rate of C. braarudii was on average 69.5% higher (0.76d-1) when compared with E. huxleyi (0.44d-1) (P=0.005). Results from biochemical analyses revealed that this strain of C. braarudii has high protein and lipid content, 34.6% and 22.1% of total dry weight, respectively. The fatty acid (FA) profile was mainly composed of ω-3 PUFA, 64.1% total FA, with high levels of DHA and EPA. E. huxleyi revealed lower (P<0.001) protein and lipid contents and a fatty acid profile rich in DHA but poor in EPA. Finding alternative sources to ω-3 PUFA from wild fish is currently a major challenge for aquaculture. Given the cell size, high growth rate and nutritional quality, C. braarudii is a promising candidate for microalgae-based diets in aquaculture, particularly of larval stages, thus contributing to sustainable aquaculture practices.
- Learning during emergency remote teaching in Portugal: higher education students' emotional snapshotPublication . Cardoso, Paula; Morgado, Lina; Paiva, Ana; Paz, João; Mendes, Elisabete; Loureiro, Ana; Messias, Inês; Oliveira, Nuno Ricardo; Runa, Ana Isabel; Seco, Carlos; Pereira, Hugo; Vieira, Márcia de FreitasThis chapter will address results of LE@D’s project “Teaching in Times of Emergency: Digital Transition,” which focused on the experience of rapid digital transition to an “emergency teaching,” a scenario quite different from distance education. Through a mixed methods approach, data was collected through an online questionnaire applied to students and videoconference interviews conducted with both higher education faculty and students. Participants in this research are students and faculty from eight Portuguese higher education institutions, four from universities (three public and one private) and four from polytechnic institutes (three public and one private), covering the regions of Lisbon and Tagus Valley, Alentejo and Algarve (Central and Southern Portugal). In this chapter, the authors present a preliminary analysis of the results obtained related to the psychological aspects experienced during this period, aiming at understanding the impact this shift has had on students’ cognitive adaptation and social and emotional processes.
- Online communication and assessment practices during the Covid Pandemic: a study of the portuguese higher education students’ perceptionsPublication . Morgado, Lina; Paz, João; Pereira, Hugo; Loureiro, Ana; Messias, Inês; Cardoso, Paula; Paiva, Ana; Runa, Ana; Seco, C.; Mendes, Elisabete; Vieira, M. F.; Oliveira, Nuno RicardoThis proposal is part of an ongoing research and presents the results on the perceptions and pedagogical practices experienced by students from various higher education degrees in Portuguese higher education institutions, during the period of social confinement determined by the Portuguese Government, due to the COVID-19 pandemic. The main objective of the general research was to understand how Higher Education faculty and students experienced the digital transition to emergency education and the pedagogical practices adopted during the period. The research was based on a mixed methods approach and, in order to address the research objectives and describe the pedagogical practices implemented, specific instruments were developed for data collection. A questionnaire was developed, aimed at students, and interviews aimed at both students and faculty, focusing on technological and pedagogical dimensions, as well as the assessment of the experience. Data collection was carried out after the first lockdown, at the end of the first semester of 2020, and took place in eight higher education institutions. In this paper we will present a preliminary analysis of Questionnaire results related to two dimensions: online communication and assessment.
- Treino personalizado: recomendações para a elevação da qualidade do serviço prestadoPublication . Teixeira, Diogo; Pereira, Hugo; Sousa, Ana; Chaves, César; Ruivo, Rodrigo; Asseisseira, Pedro; Dias, Amândio; Monteiro, Diogo; Cid, LuisA intervenção individualizada estruturada através do treino personalizado é uma ferramenta importante para os profissionais de exercício físico e um serviço de potencial relevo na saúde e bem-estar dos praticantes. O treino personalizado é uma prática desenvolvida nacionalmente por milhares de profissionais e relativamente comum em vários contextos, onde os ginásios e health clubs se destacam em particular. Considerando a reduzida produção nacional de literatura neste tópico, e assumindo a importância e relevância da emissão de recomendações atualizadas e que derivem de limitações concretas observadas em contexto de prática, este artigo apresenta como objetivo principal emitir orientações e recomendações operacionais que permitam uma aferição e regulação do trabalho implementado neste contexto, visando uma reflexão crítica e melhoria do serviço prestado. As recomendações emitidas também procuram, em acréscimo ao apoio associado ao desempenho da função profissional, ajudar na clarificação do que deverá constituir e delimitar a prestação deste serviço perante a visão de um praticante, apontando um caminho que vise uma uniformização de comportamentos e ações ética e profissionalmente recomendáveis, que possam e devam ser assumidas na prestação do treino personalizado, e permitam criar uma imagem social mais clara, objetiva e delimitada deste serviço individualizado
