Abstract
This paper assesses Brazil's real convergence (1822-2019) through unit root tests and Markov Regime-Switching (MS) models in three different scenarios: towards (i) other six Latin American countries (LA6); (ii) Portugal; and (iii) the technological frontier country, the US. The extended unit root test results favour Brazil's very long-run real convergence towards LA6 and Portugal, but not the US. The estimated MS models, involving two different regimes, real convergence and real non-convergence/divergence, capture institutional quality's positive effect in promoting Brazil's real convergence.

Abstract
The thermal SPA sector is currently experiencing a stable growth trend, which according to the World Tourism Organization (WTO) is expected to continue over the upcoming years. In Portugal, the sector has a very significant profile, with the existence of almost a hundred SPAs and thermal SPAs that generate a business volume (direct and indirect) of over 30 M€ per year. Although the beginning of the process of digital transformation of the sector is already visible, there is no holistic view of the sector which means that the currently existing information systems (IS) do not present a useful response to the needs faced by the sector. Therefore, an architecture proposal was conceived and described for an IS that provides a useful, efficient, and agile response to the needs of the entire thermalism sector and its stakeholders. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Abstract
The growing use of technology and social media has resulted in the emergence of digital influencers, a new profession capable of changing the mentalities and behaviours of those who follow them. This study arises to better understand the potential impact digital influencers might have on the Portuguese population’s purchase behaviour and patterns, and for this purpose, seven hypotheses were formulated. An online questionnaire was conducted to respond to these theoretical assumptions and collected data from 175 respondents. A total of 129 valid answers were considered. It was possible to conclude that purchase intention does not necessarily translate into a purchase action. It was also concluded that the relationship between social network use and the purchase of products/services recommended by influencers is only significant for Instagram. Furthermore, individuals’ Generation is not significantly linked with purchasing a product/service recommended by influencers. Furthermore, a small percentage of respondents have also identified themselves as impulsive shoppers and perceived Instagram as their favourite social network. With the results of this study, it is also possible to state that the influencer’s opinion was classified as the last factor considered in the purchase decision process. Additionally, there is a weak negative association between purchasing a product/service recommended by influencers with sponsorship disclosure and remunerated partnership, which decreases credibility and discourages purchasing.

Abstract
The pursuit of happiness is a fundamental human goal that has been studied by philosophers, theologians, and scientists for centuries. Despite its universal importance, the definition and means of achieving happiness vary greatly across cultures and individual experiences (Uchida, Norasakkunkit and Kitayama, 2004). Cultures have different beliefs, values, and customs that shape their understanding of happiness. For example, some cultures may place a higher value on material wealth and success, while others may prioritize spiritual fulfilment or strong relationships (Joshanloo and Weijers, 2014). In this autoethnographic paper, I reflect on my own personal journey towards happiness during a one-year travel across 22 countries within southern Africa, southeast Asia, and south America, focusing on the first part of the trip – southern Africa. Autoethnography is a qualitative research method that involves the researcher reflecting on their personal experiences and cultural positionality in order to understand and analyse cultural phenomena (Bunyan, 2021). It combines elements of autobiography and ethnography, as the researcher uses their own experiences as a way to explore and understand the cultural context in which they participate (Hamilton, Smith and Worthington, 2008). Through the use of personal narrative and cultural analysis, I delve into the ways in which my own cultural background and societal expectations shaped my understanding of happiness. I also explore the ways in which immersing myself in a new culture and community impacted my pursuit of happiness and well-being. By reflecting on my own experiences and observations, I aim to shed light on the complexities of the pursuit of happiness and the potential for personal and cultural growth that can result from stepping outside of one's comfort zone. Through this autoethnographic lens, we hope to offer a unique and personal perspective on the pursuit of happiness, and to encourage readers to consider the cultural and individual factors that influence their own pursuit of this universal goal. We also reflect on how innovation and technology, essential to business, may not be as important to achieve happiness in certain contexts. This essay is a call for reflection on what truly matters in life.
