Abstract
This article studies the influence of digital marketing in consumers' making process regarding plant-based diet. The investigation was exploratory, and adopted a descriptive method, consisting of 11 face-to-face interviews and four focus groups with plant-based diet adopters and supporters. A non-probabilistic convenience sampling method was used to recruit participants. This study found that supporters differ from adopters of a plant-based diet regarding their concerns with certification and the difficulty in understanding labels.

Abstract
In this paper, we address a subtopic of the broad domain of audio enhancement, namely musical audio bandwidth extension. We formulate the bandwidth extension problem using deep neural networks, where a band-limited signal is provided as input to the network, with the goal of reconstructing a full-bandwidth output. Our main contribution centers on the impact of the choice of low-pass filter when training and subsequently testing the network. For two different state-of-the-art deep architectures, ResNet and U-Net, we demonstrate that when the training and testing filters are matched, improvements in signal-to-noise ratio (SNR) of up to 7 dB can be obtained. However, when these filters differ, the improvement falls considerably and under some training conditions results in a lower SNR than the band-limited input. To circumvent this apparent overfitting to filter shape, we propose a data augmentation strategy which utilizes multiple low-pass filters during training and leads to improved generalization to unseen filtering conditions at test time.

Abstract
This chapter builds on the main contributions in the literature that associate tourism with student mobility, particularly in Europe, positioning tourism both as a motivator and an enhancer of mobility’s success, namely by developing transversal skills and loyalty to the host destination (e.g. intention to return to the host destination for tourism or work and its recommendation to peers). A qualitative study was conducted with 32 exchange students that spent one or two semesters at the same Portuguese University by using focus groups for collecting participants’ views and experiences. Data was subject to thematic content analysis. Participants in this study agreed that they travel as much as they can during their mobility, being an essential part of their intercultural experience. Their narratives and dialogues evidenced that travelling contributes to developing transversal skills important for their self-awareness and for their future professional careers, such as time management, money management, and intercultural communication. © 2021, Springer Nature Switzerland AG.

Abstract
Physical and cognitive rehabilitation based on natural interaction and VR has been on our horizon for several years, and we have been conducting experimentation towards that goal through several exploratory research initiatives.This article addresses some aspects of the state-of-the-art of VR in healthcare and well-being, with opportunities in the domain of rehabilitation based on natural interaction and VR being analyzed and put in perspective with the SmartAL ecosystem roadmap.
