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
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
Worldwide organic food consumption has registered a consistent rise in recent years. Despite the relevant body of literature on the topic, it is necessary to further understand the antecedents of purchase intention. This article aims to identify the factors that influence the consumer's intention to purchase organic food. It extends the theory of planned behavior model by including environmental concerns, health concerns, and perceived quality as determinants of attitude toward organic food products. Additionally, it considers the effect of product availability on consumers' perceived behavioral control. This article includes a quantitative study that was conducted in Portugal in 2020 (n = 206). Structural equation modeling was used to test the proposed set of research hypotheses. In line with extant literature, this study confirmed that attitude toward organic food is the main determinant of purchase intention. Additionally, it demonstrates that health concerns and perceived quality have a significant impact on attitude toward organic food. The impact of environmental concerns on attitude was not confirmed by this study. Based on these findings, it is recommended that managers stress health benefits and quality of organic food in order to foster positive attitudes and consequently leverage purchase intention.

Abstract
Despite the current importance of international retirement migration for both academics and practitioners, the extant literature on the topic is still scarce and mostly focused on short-period migration flows from wealthy and northern countries to cheaper and warm-weather destinations. This article aims at shedding light on the role of tourism in prospective migrants' decision-making process, considering the framework provided by the push-pull model, which is often used to explain both migration and tourism. A qualitative study was conducted, comprising ten in-depth interviews with 45+ year-old Brazilian citizens who intend to move to Europe after retirement. Results show that tourism is important for prospective migrants to evaluate possible migration destinations, as some of the most relevant migration pull factors (e.g., safety) are easily assessed during tourism experiences. Participants in this study also carefully plan tourism activities prior to their decision to migrate in order to get a more realistic notion of what the destination is like for residents. Overall, this study demonstrates that tourism is particularly important for several stages of migrants' decision-making process.

Abstract
The main aim of this article is to explore the relationship between tourism experience and international retirement migration. Despite the current trends in international tourism and the marketing efforts of some destinations to attract retired foreigners, contributions in the literature about prospective migrants' decision process are still rare, particularly regarding long-term migration and beyond the traditional north-south flows from the wealthy countries to warmer and more affordable destinations. Building on migration theories and models, including the recently proposed push-pull plus model, this article includes a qualitative study with 12 Brazilian citizens with varying degrees of intention to migrate to Europe after retirement. Results show that tourism acts as an important facilitator of prospective migrants' decision process, functioning as a mediating driver of future migration, by enabling to gather information and to experience the living conditions in the destination. Overall, this article demonstrates that the push-pull plus model is particularly interesting to capture prospective migrants' dynamic decision process. Implications for managers and future research suggestions are also provided.

Abstract
Social media are transforming relationships with customers for all sectors, including tourism. Since the search for information is a critical aspect of tourist purchase decision process, the importance of social media for tourism is evident. However, the presence of tourism brands in social media is not enough to have an impact on tourist purchase decisions: it is necessary to generate engagement. This chapter aims to conceptualize tourist engagement on social media and identify tourist engagement indicators. Tourist engagement was conceptualized through a literature review that identified four dimensions of engagement: popularity, commitment, virality, and post engagement. A set of indicators is proposed to measure tourist engagement in each of these dimensions. The proposed TSM engagement framework was validated through a mixed-method approach, using secondary data and interviews carried out with Brazilian tourist destinations.
