The purpose of this study is to compare the spatial distribution of different types of Airbnb hosts – based on a novel typology – and to investigate their association with neighbourhood characteristics in Brussels.

This study describes the location of Airbnb dwellings across the types of hosts and use spatial tests to compare their distributions to the traditional hospitality industry. With regression models, this study examines the relationship between the provision of Airbnb listings and neighbourhood indicators.

While different types of hosts offer their listings in the same urban space, they also cover different areas and exhibit different clustering processes. Their locations are associated with structural, socio-economic and demographic neighbourhood characteristics that vary across the types and provide support for the new typology.

This study focuses on the type of Airbnb hosts and their listings in one year, 2019. It would be worthwhile to apply the typology to other cities and to observe how the distributions change over time, including the period of the COVID-19 pandemic.

To the best of the authors’ knowledge, this paper is the first to suggest a finer typology of Airbnb hosts than the regular distinction into professional and non-professional types and reveals how hosts differ in the location of their Airbnbs.

We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

This paper aims to identify if there is an impact of the rating announcements issued by the agencies on the returns of the stocks of Brazilian companies listed on Brasil Bolsa Balcão, from August 2002 to August 2018, identifying which types of announcement (upgrade, downgrade or the same initial classification) cause variations in prices around the date of disclosure of the rating.

The event study methodology was applied to verify the market reaction around the announcement dates in a 21-day event window (−10, +10). The market model was used to calculate the abnormal returns (ARs), and subsequently, the accumulated ARs.

The hypotheses tests allowed to verify that the accumulated ARs are different, before and after the three types of rating announcements (upgrades, downgrades and the same classification); in upgrades, the mean of accumulated ARs increases in the days before the event, while in downgrades, this increase occurs after the event. This paper concluded that the rating announcements have an impact on the return of stock of the Brazilian market and that the market reaction occurs most of the time before the event happens, which indicates that the market can anticipate the information contained in the changes in credit ratings.

The results have considerable implications for portfolio managers, institutional investors and traders. It facilitates investment decision-making in the face of rating classification announcements. Market participants can pay more attention to their investment strategies and asset allocation during periods of risk rating announcements. Additionally, traders can understand the form of investment strategy for superior earnings.

The importance of the study is related to the fact that the results may explain the causes of specific movements in the Brazilian financial market related to a source of information that may or may not be able to influence the decisions of the financial agents that operate in this market. The justification is centred on the idea that, for investors who somehow react to the announcements, it is relevant to understand the impact of rating classifications on companies, as access to such information allows for more conscious decision-making.

The purpose of this paper is to offer instructors a real managerial dilemma faced by a prestigious Brazilian jewelry company as it decides how it should expand into two Asian countries: China and South Korea.

The authors followed guidelines for developing teaching cases as those suggested by Gill's (2011) seminal contribution, Informing with the Case Method.

Since this is a teaching case, there are no “findings” in the usual sense of the word related to traditional empirical studies.

Data for the case came mainly from the stated visions and opinions of the firm's spokesperson and may reflect his own particular (though influential) views. The authors also used public secondary data from consulting companies, market research firms and business magazines. Although these accounts may be partial, this is not a severe limitation since a teaching case is expected to provide some information, but not a full set of information, in order to better reflect real managerial situations.

This case study may help students understand and “live trough” a real managerial dilemma, related to international expansion to a rather distinct environment from those the firm has been accustomed to.

This teaching case brings relevant material for in-class discussion of a successful emerging market firm that has successfully paved its way into developed Western markets and now seeks to expand into Eastern lands. Decisions related to strategic positioning and international marketing make the core of the managerial dilemmas that the firm has to face.

The purpose of this paper is to present a simple and effective method to search the optimal turn-on and turn-off angles on-line for the control of the switched reluctance motor (SRM). The optimal turn-on and turn-off angles are defined as the ones that can meet torque production requirements with minimum copper loss.

The optimal turn-on and turn-off angles are first defined based on the analysis of the SRM losses and torque production principles. Then the algorithm for optimal angles searching is developed, and the searching parameters are determined through analytical computation. The optimal angles are approached on-line with iterative process. Simulation and experiments are finally performed to verify the proposed method.

The presented method can meet torque production requirements while copper loss is minimized. The optimal turn-on and turn-off angles are generally approached within five phase cycles for most of the SRM operation modes. Furthermore, the SRM drive system using the presented method exhibits good dynamics during starting and sudden load operations.

The presented method is simple, and implementation of it is easy. It is an eligible candidate for industrial applications where energy conversion efficiency is crucial.

The optimal turn-off angle definition that considers both torque production and copper loss minimization is proposed. The turn-on and turn-off angles are searched independently on-line with little SRM geometrical information. The searching steps are derived through analytical computation and qualitative analysis so that both the searching speed and algorithm convergence are balanced.

Primary and secondary data were used to prepare this case. For primary data, the company’s owner was interviewed on multiple occasions. The authors also used Vino Mundo company materials, websites and internal reports in developing the case. Other secondary data sources were used to obtain information on the external environment, industry, demographics and market. Secondary data sources included the World Bank, INEC and Urban and Cities Platform data sets.

Vino Mundo was a restaurant and event space in a beautiful mountain villa outside of San Jose, Costa Rica. It offered international cuisine and wine. The founder and owner, Guillermo Aguilar, faced challenges with sustaining and growing his business in the wake of the global pandemic in 2022. Although he had a strong vision for Vino Mundo, he needed to revisit his strategic plan, especially in marketing. He had many decisions to make in 2023.

The case is primarily designed for upper-level undergraduate and graduate marketing courses. It is well-suited for subjects such as marketing management, entrepreneurial marketing, marketing in emerging markets, family and small business marketing and global marketing. It covers topics including marketing strategy and tactics, new product development, segmentation, targeting, positioning, strategic marketing management, family businesses and emerging markets.

The purpose of this research is to explore how text-emoji mismatch impacts consumers’ perceptions of authenticity and helpfulness in online reviews, examining the mediating effect of processing fluency and the moderating effects of response type and social distance.

Three between-subject experiments were conducted on Credamo and Wenjuanxing to test the hypotheses proposed in this research. The primary data analysis methods used were ANOVA and bootstrap analysis.

Study 1 found that consumers’ perceived helpfulness and authenticity of online reviews decline when the text and emojis do not match, with processing fluency mediating this effect. Study 2 revealed that humorous responses from firms to reviews with text-emoji mismatches enhance consumers’ perceived authenticity and helpfulness. Study 3 demonstrated that when potential consumers perceive a greater social distance from the reviewers, the negative impact of text-emoji mismatch is mitigated.

This study contributes to the fields of consumer reviews and emoji usage by examining how the relationship between emojis and text in online reviews (match vs. mismatch) affects consumers’ perceived authenticity and helpfulness. We also propose strategies for how firms can mitigate the negative impact of text-emoji mismatch.

In the twenty-first century, the family has been turning towards a greater plurality of training paths, situations, family and parental arrangements. However, despite changes in legislation, values, representations and practices, the word family remains inexorably associated with the heterosexual bi-parental model. This paper aims to contribute to the knowledge of the family dynamics of non-heterosexual people, mainly concerning the process of transition to parenting, in relation to family changes in Portuguese society. To do so this study aims to analyze four in-depth interviews¹ with young adults, women and men who have a homoconjugality relationship and a project of parenting in mind.

Based on a qualitative methodology the study intends to discuss issues related to the challenge of heteronormativity, equality within the couple, projects and gender representations of parenthood and in particular what it means for the men and women interviewed, to be a father and to be a mother in a same sex couple and how they project themselves as fathers and mothers.

The study discusses all these issues always in relation to the biographical trajectories, the history and life as a couple and the structural and individual resources, such as school and professional qualifications. It also analyzes the main difficulties experienced in revealing their sexuality to the significant others and the difficulties / strategies they anticipate in relation to the parenting project.

The authors conclude that female interviewees show greater independence of a male figure in relation to their parental projects and anticipate less difficulty in their parental skills compared with the gay man interviewed.

To analyze the dynamics of parenting in same-sex couples, this study also points out to the need to construct a model of analysis capable of articulating structural factors, such as job insecurity and heteronormativity, biographies and individual resources and profiles of conjugal interactions.
