Abstract
One of the current trends in the luxury market is the development of offers targeted to the millennial generation. In fact, this generation is seen as a potentiator of market growth, considering that the future of the luxury sector will depend on the capacity to reach this generation. This topic is particularly relevant for the marketing area, namely for the tourism sector. Another of the major trends for the tourism sector is the sustainability issue, with an emphasis on ecotourism. In this work we discuss the main contributions of the literature that allow to interlink the domains of luxury marketing, millennial generation, and ecotourism, proposing a set of hypotheses for future research. © 2019 AISTI.

Abstract
This article studies the economic crisis' impact on consumers' behavior, and aims to help defining green marketing strategies appropriate for these periods. We conducted a survey to 412 Portuguese individuals. The majority of the respondents shows a medium or high green consumer behavior, and demonstrates reduced consumption during crisis. The purchase of green products is more present in products whose use cost is lower than the use cost of the alternative products. The crisis may have a bipolar effect on green consumption, encouraging certain practices and reducing others.

Abstract
This article addresses the zone of tolerance (ZOT) as a diagnosis tool for managing the quality of information systems' (IS) service delivered to internal customers. It aims to contribute to a better understanding of internal customers' ZOT by considering the frequency of use and skills in IS as explanatory factors. A survey was administered to the internal users of one company's IS department. 276 valid questionnaires were obtained, representing a response rate of 70%. The results show that internal customers have narrow zone of tolerance, which differ according to the users' IS skills and how frequently they use the IS support service; occasional users and skilled users are the least susceptible to heterogeneity in the service delivery. This approach enables IS management to focus on users' expectations, making service delivery more efficient by allocating the resources where they are most needed.

Abstract
This paper aims to provide a closer look at consumers' attitude toward Facebook advertising by providing a comparison between attitude toward brand posts and ads, a topic that has been disregarded in the extant literature. It also considers the relationship with the users' ad avoidance and electronic word-of-mouth communication. An exploratory quantitative analysis was performed by means of a structured self-administered questionnaire. 385 individuals aged between 18 and 44 participated in the study. The results include evidence on respondents' more favourable attitude toward brand posts than toward Facebook ads. Moreover, ads are considered more annoying by those who spend more time on Facebook. These results help shed the light on how Facebook users handle ads and brand posts, offering some clues for a more effective social media marketing strategy.
