Abstract
Purpose
This paper aims to compare the possible environmental impacts of different rehabilitation solutions proposed to a case study of a Portuguese vernacular building, bearing in mind the need to search for less impactful practices in accordance with global agendas and, simultaneously, the importance of preserving heritage assets.
Design/methodology/approach
The two proposed solutions differ from each other in the selection of materials, varying from the exclusive use of conventional contemporary materials to the use of locally sourced and natural-based materials, considering the Portuguese and local scenario. Results obtained from Life Cycle Assessment procedures are the basis of comparison, which were developed using a Building Information Model (BIM)-integrated analytical plugin.
Findings
Producing Heritage Building Information Model (HBIM) models was essential to the analysis, and therefore is a vital part of the used methodology; nevertheless, the modelling of heritage buildings itself plays an important part in preserving heritage assets once it provides precise documenting and managing tools. The results depict variation in values for different indicators in both cases, whose interpretation might need further development to get to deeper conclusions. It has been found that the software tools are still not well adapted to analyse heritage or historic buildings, and therefore adaptations had to take place to overcome these limitations.
Originality/value
The study distinguishes itself by involving the production of HBIM models and the use of BIM-integrated Life Cycle Assessment plugins as well as its analyses, to validate this approach.

Abstract
Purpose
Explore the role of traditional cafés in Lisbon and botequins in Rio de Janeiro in the history and culture of their respective cities, based on an analysis of the comments published on TripAdvisor.
Design/methodology/approach
Using a mixed methodology, 7,430 evaluations were analyzed, of which 5,473 were for Portuguese cafés and 1,957 for Brazilian botequins. A content analysis and statistical treatment were carried out. A line-by-line analysis was also conducted to code the emotions reported in the customer reviews.
Findings
The analysis categorized the comments into Gastronomy, Nostalgia, History and Heritage, and Quality of Service. Nostalgia garnered the highest percentage of positive comments for both Portuguese cafés and Brazilian botequins. These results emphasize the importance attached to sentimental connections and historical narratives, particularly those associated with notable individuals who frequented these places. Furthermore, no statistically significant differences were identified according to the type of establishment, which suggests a consistent pattern between cafés and traditional botequins.
Practical implications
Draws attention to the importance of a collaborative partnership between restaurant owners and tourism authorities. This strategic alliance not only serves to raise the cultural profile of cities, but also generates substantial economic benefits. It also ensures the lasting legacy of these historic establishments, celebrating the past, enriching the present and safeguarding the future.
Originality/value
Studying the cafés of Lisbon and the botequins of Brazil is important not only for understanding the history and culture of these countries but also for analyzing issues related to socialization, identity, artistic expression and urban transformations.

Abstract
Purpose
This study aims to explore the role of socially responsible human resource management (SRHRM) as a key driver of employee voice behaviour. The hypotheses included that these human resources management (HRM) practices strengthen employees’ motivation to voice their opinions by increasing their work engagement (WE), thereby encouraging them to share their ideas and concerns about their organization more actively. The hypotheses also proposed that this effect is especially pronounced when employees experience a heightened sense of psychological safety.
Design/methodology/approach
A survey-based correlational study was conducted with a sample of 289 participants to analyse the proposed relationships between the selected variables.
Findings
The results indicate that SRHRM and WE are significantly associated with both promotive and prohibitive voice behaviour among employees. In addition, the moderated mediation model revealed that employees who perceive their organization as adopting SRHRM practices display higher levels of WE, which in turn increases these individuals’ likelihood of engaging in both types of voice behaviour. This relationship is particularly strong for promotive voice when employees experience high levels of organizational psychological safety.
Research limitations/implications
The findings are limited by the cross-sectional research design, which restricts causal inference.
Practical implications
By adopting people-centred HRM practices, organizations can foster psychologically safe environments that enhance employees’ willingness to engage in behaviour beneficial to their organization, such as WE and voice behaviours.
Originality/value
The results highlight the critical role of SRHRM and offer evidence-based insights into how interventions can foster positive employee behaviours and attitudes, including WE and voice behaviour.

Abstract
Purpose
This study aims to critically evaluate the competitiveness of Transformer-based models in financial forecasting, specifically in the context of stock realized volatility forecasting. It seeks to challenge and extend upon the assertions of Zeng et al. (2023) regarding the purported limitations of these models in handling temporal information in financial time series.
Design/methodology/approach
Employing a robust methodological framework, the study systematically compares a range of Transformer models, including first-generation and advanced iterations like Informer, Autoformer, and PatchTST, against benchmark models (HAR, NBEATSx, NHITS, and TimesNet). The evaluation encompasses 80 different stocks, four error metrics, four statistical tests, and three robustness tests designed to reflect diverse market conditions and data availability scenarios.
Findings
The research uncovers that while first-generation Transformer models, like TFT, underperform in financial forecasting, second-generation models like Informer, Autoformer, and PatchTST demonstrate remarkable efficacy, especially in scenarios characterized by limited historical data and market volatility. The study also highlights the nuanced performance of these models across different forecasting horizons and error metrics, showcasing their potential as robust tools in financial forecasting, which contradicts the findings of Zeng et al. (2023)
Originality/value
This paper contributes to the financial forecasting literature by providing a comprehensive analysis of the applicability of Transformer-based models in this domain. It offers new insights into the capabilities of these models, especially their adaptability to different market conditions and forecasting requirements, challenging the existing skepticism created by Zeng et al. (2023) about their utility in financial forecasting.

Abstract
Purpose
The study aims to evaluate and compare the quantity and quality levels of corporate social responsibility disclosure (CSRD) practices on the websites of the largest Islamic and conventional banks worldwide.
Design/methodology/approach
Two indices were developed: the quantity index, consisting of seven categories, and the quality index, which includes eight characteristics, to adopt the quantitative content analysis of the global leading 94 Islamic and 100 conventional banks’ websites.
Findings
The results show that conventional banks have higher levels of CSRD quantity and quality on their websites than those of Islamic banks. The study found that the products and services category is the most disclosed by largest Islamic and conventional banks worldwide, while environment and energy information is the lowest for Islamic banks and employee and human resource information is less common for conventional ones. The analysis reveals low levels of CSRD quantity and quality on Islamic banks’ websites (43.69% and 54.56%) and high levels on conventional banks’ websites (70.84% and 73.26%).
Research limitations/implications
The study focuses on analyzing the quantity and quality of CSRD on English-accessible websites of the largest Islamic and conventional banks in 2022, focusing on English as a uniform language for data collection because it analyzed 194 websites from 48 countries with over 20 languages.
Practical implications
The results of this study are likely to be valuable to many interested parties because they inform investors about the status of CSRD practices on the largest Islamic and conventional banks’ websites worldwide and how they disclose such information. To ensure investor satisfaction and accurate investment decisions, these global banks should provide comprehensive and high-quality CSR information on their websites to show how they contribute to CSR activities. For scholars, its limitations may be helpful in their future research.
Originality/value
The originality of this paper derives from its focus on largest-world Islamic and non-Islamic banks, collecting primary data directly from their websites, and offering valuable theoretical, methodological and practical insights.

Abstract
Purpose
The study aims to analyze the effect of the previous preparation and the work carried out in the field during a study trip on the development of competencies in agribusiness students.
Design/methodology/approach
The destination was the pineapple area of the Papaloapan Lower Basin in Mexico, and 42 students from 6 different semester levels participated. The students answered a test prior to the trip, received an evaluation for their activities in the field and prepared reports and posters as products of the experience. The relationship between the scores obtained was examined through a comparative analysis.
Findings
The findings are framed in the cyclical model of experiential learning with four stages (feeling, watching, thinking and doing) by Kolb (1984). It is found that the acquisition of specific knowledge about what the experience will entail leads to better preparation, motivation and confidence to live the experience (potentiation of feeling and watching). In turn, specific knowledge and better use of experience promote the development of problem solving, interpersonal and communication skills (potentiation of thinking and doing).
Research limitations/implications
Statistical representativeness is not a quality of the study since it is based on a comparative analysis.
Originality/value
The study analyzes an educational component of great value in the business area, about which little is known in the agribusiness subarea.
