Abstract
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.

Abstract
Purpose
Research on showrooming has focused on investigating its antecedents, motivators and characteristics, leaving a gap regarding its consequences. Our study intends to build a comprehensive framework to examine the role of showrooming behaviour on showrooming satisfaction and customer loyalty while exploring its antecedents.
Design/methodology/approach
Data collection took place in Brazil through an electronic form distributed on social media, reaching 393 people. After eliminating responses from those who had no showrooming experience, the final sample consisted of 310 respondents. The questions captured the costs and benefits of showrooming, internet savviness, showrooming behaviour, satisfaction with showrooming and customer loyalty (i.e. repurchase intention and positive word-of-mouth). We performed partial least squares data analysis by means of the statistical package Smart PLS 4.
Findings
The results show that showrooming behaviour is positively influenced by internet savviness and the perceived benefits of showrooming but not by the perceived costs of showrooming. In addition, showrooming behaviour positively influences satisfaction with showrooming and customer loyalty (i.e. repurchase intention and positive word-of-mouth). Finally, we identify satisfaction with showrooming as a mediator between showrooming behaviour and customer loyalty.
Originality/value
Given that the implications of showrooming behaviour on customer loyalty remain understudied, this work contributes to the marketing literature by demonstrating the influence of showrooming behaviour on satisfaction with showrooming and its consequential effect on customer loyalty. Moreover, we confirmed the mediating role of customer satisfaction in the relationship between showrooming behaviour and customer loyalty.

Abstract
Purpose
Despite the growing competition between higher education institutions and the empirical evidence that the brand is a relevant determinant of consumer preference, research studies on negative consumer–brand relationships (CBRs) are still scarce. Thus, this research intends to fill this gap, determining the antecedents of brand hate in educational institutions and identifying gender differences regarding the determinants of brand hate.
Design/methodology/approach
A survey was carried out with 450 current students from higher education institutions. The proposed model was tested using partial least squares structural equation modeling (PLS-SEM) in SmartPLS3.
Findings
According to the results, previous negative experiences are the most significant driver of brand hate, with higher emphasis on male students. In this sense, investment in customer experience management (CXM) consists of a relevant strategy for higher education institutions. It was also observed that female students develop hate for ideological incongruity (ethical/moral behavior) and symbolic incongruence (lack of brand identity), revealing unprecedented facets of the phenomenon.
Originality/value
This research extends the studies’ negative CBRs to educational institutions. It explores gender differences related to brand hate; a topic not explored before, but that enables a targeted approach of brand strategies. Finally, it provides managerial implications allowing the strategy to reduce negative CBRs and their consequences in educational institutions.

Abstract
Purpose
This study aims to assess the online presence of three Portuguese low-density territories and analyze the communication strategies employed by public and private entities within each municipality. The alignment between public and private entities within each municipality is also examined as a potential factor that could impact the effectiveness of digital communication strategies.
Design/methodology/approach
A qualitative methodology that employed content analysis and interviews to gather data from selected public and private entities in each of the municipalities under study was used.
Findings
Despite the widespread availability of digital communication tools, the municipalities under study are yet to fully exploit their potential to promote and publicize their offerings. This could be attributed to several factors such as a lack of knowledge and/or resources and a defective strategic approach to digital communication.
Practical implications
The major obstacle in maximizing the potential of digital communication tools in low-density destinations was not solely a result of restricted access. Rather, it was largely due to insufficient knowledge and resources required for their effective utilization, coupled with a lack of aligned vision among various stakeholders.
Originality/value
The competitive landscape in which tourist actors operate has transformed significantly because of the widespread adoption of digital communication led by social networks. However, studies exploring digital communication in low-density territories are still scarce. This study adds new insights into the main factors that hinder the efficient use of digital communication in these regions.

Abstract
Purpose
This study aims to investigate the existence of delimitations more suited to the emergence of generations in Brazil, and to assess generational perceptions on constructs of the work environment and their influences on organizational commitment.
Design/methodology/approach
The perceptions of 102,540 respondents employed by 394 organizations were classified into nine constructs. The methodology used entailed an initial confirmatory factorial analysis, which was undertaken to investigate the validity of the proposed measurement model. Regression analyses were applied to test the relationship between work environment and commitment.
Findings
The results highlight that the Baby Boomer generation attributed more value to the meaning of work and corporate social responsibility. Meaning of work, learning and development were given a high level of importance in the results for Generation X. Generation Y values learning and development, relationships with co-workers and Work-life balance more than the other two generations.
Research limitations/implications
This research is classified as a cross-sectional study that does not allow us to substantiate whether differences between the groups were caused by influence of generations or the age of respondents. Therefore, nationwide surveys capable of offsetting the age effect on generational differences are still necessary. Another constraint is related to the fact that only data from the survey that annually elects the “Best Companies to Work for in Brazil” were used for undertaking this study. Moreover, because all variables were collected simultaneously from the same source, the authors recognize that the results could have problems related to common method biases.
Practical implications
The authors believe that the identification of critical dimensions of workers’ perception regarding the work environment equips human resources professionals with the ability to implement policies and practices that align people management with the differing desires of each generation, effectively ensuring commitment from these professionals.
Social implications
This study may contribute to researchers by highlighting the need for temporal outlines suited to the Brazilian reality, which might also inspire further research on the country’s generations, even associating them with other themes, such as values, personality and professional motivation.
Originality/value
As the main contributions, the authors have sought to highlight that generational differences may be related to specific periods in each country’s historical context. The authors also show the determining factors influencing each generation’s affective commitment and justify each of their choices.

Abstract
Purpose
This paper aims to conceptualize impacts of higher education institutions (HEIs) on sustainable development (SD), complementing previous literature reviews by broadening the perspective from what HEIs do in pursuit of SD to how these activities impact society, the environment and the economy.
Design/methodology/approach
The paper provides a systematic literature review of peer-reviewed journal articles published between 2005 and 2017. Inductive content analysis was applied to identify major themes and impact areas addressed in the literature to develop a conceptual framework detailing the relationship between HEIs’ activities and their impacts on SD.
Findings
The paper identifies six impact areas where direct and indirect impacts of HEIs on SD may occur. The findings indicate a strong focus on case studies dealing with specific projects and a lack of studies analyzing impacts from a more holistic perspective.
Practical implications
This systematic literature review enables decision-makers in HEIs, researchers and educators to better understand how their activities may affect society, the environment and the economy, and it provides a solid foundation to tackle these impacts.
Social implications
The review highlights that HEIs have an inherent responsibility to make societies more sustainable. HEIs must embed SD into their systems while considering their impacts on society.
Originality/value
This paper provides a holistic conceptualization of HEIs’ impacts on SD. The conceptual framework can be useful for future research that attempts to analyze HEIs’ impacts on SD from a holistic perspective.

Abstract
Purpose
This study aims to estimate the overall SARS-CoV-2 seroprevalence and evaluate the accuracy of an antibody rapid test compared to a reference serological assay during a COVID-19 outbreak in a prison complex housing over 13,000 prisoners in Brasília.
Design/methodology/approach
The authors obtained a randomized, stratified representative sample of each prison unit and conducted a repeated serosurvey among prisoners between June and July 2020, using a lateral-flow immunochromatographic assay (LFIA). Samples were also retested using a chemiluminescence enzyme immunoassay (CLIA) to compare SARS-CoV-2 seroprevalence and 21-days incidence, as well as to estimate the overall infection fatality rate (IFR) and determine the diagnostic accuracy of the LFIA test.
Findings
This study identified 485 eligible individuals and enrolled 460 participants. Baseline and 21-days follow-up seroprevalence were estimated at 52.0% (95% CI 44.9–59.0) and 56.7% (95% CI 48.2–65.3) with LFIA; and 80.7% (95% CI 74.1–87.3) and 81.1% (95% CI 74.4–87.8) with CLIA, with an overall IFR of 0.02%. There were 78.2% (95% CI 66.7–89.7) symptomatic individuals among the positive cases. Sensitivity and specificity of LFIA were estimated at 43.4% and 83.3% for IgM; 46.5% and 91.5% for IgG; and 59.1% and 77.3% for combined tests.
Originality/value
The authors found high seroprevalence of anti-SARS-CoV-2 antibodies within the prison complex. The occurrence of asymptomatic infection highlights the importance of periodic mass testing in addition to case-finding of symptomatic individuals; however, the field performance of LFIA tests should be validated. This study recommends that vaccination strategies consider the inclusion of prisoners and prison staff in priority groups.

Abstract
Purpose
The purpose of this paper is to propose a new typology to leverage the different knowledge gaps existing between universities and industries. This new typology classifies interactions into training-oriented, diffusion-oriented, service-oriented, development-oriented, and research-oriented.
Design/methodology/approach
The Brazilian 2010 Census data available from the CNPq Research Group Directory were used to test the typology.
Findings
It was found that, among the five types of interactions proposed, the most frequent were the development-oriented (39 per cent), diffusion-oriented (23 per cent), and research-oriented (16 per cent) ones. These findings indicate that it is likely that university-industry (U-I) interactions have improved in terms of quality in an attempt to attain a joint higher technological development.
Originality/value
The paper provides the U-I interaction debate with a new perspective about the kinds of interactions that could effectively bridge the knowledge gaps between universities and industries, especially in a developing country context.
