Abstract
Purpose
Although there are several established frameworks for health and safety in construction, there are inadequate health and safety conditions at informal construction sites, and no framework has been designed to address this problem. The purpose of this paper is to develop a validated framework for health and safety risk management (HSRM) in informal construction sites with the aim of supporting Sustainable Development Goals 3, 8 and 11 of the 2030 Agenda, which are to ensure everyone enjoys a healthy life and to create inclusive, secure, robust and sustainable cities and human settlements, respectively.
Design/methodology/approach
The study is based on HSRM questionnaire survey and interviews with construction workers working on informal construction sites in Tanzania. A total of 13 health and safety specialists in construction were specifically chosen to validate the proposed framework for HSRM in informal construction to determine its applicability, efficacy and adaptation.
Findings
The validation results demonstrated that all of the suggested metrics within the framework for HSRM in informal construction scored higher than the test value, proving the framework’s feasibility
Originality/value
This research adds to the body of knowledge on the issue in a never-before-seen setting. To the best of the authors’ knowledge, this study is the first empirical study in Tanzania to develop and validate a framework for HSRM in informal construction.

Abstract
Purpose
This paper reviews the recent collapse of two cryptocurrency enterprises, FTX and Celsius. These two cases of institutional bankruptcy have generated criminal charges and other civil complaints, mainly alleging fraud against the CEOs of the companies. This paper aims to analyse the fraud leading to these bankruptcies, drawing on key concepts from the research literature on economic crime to provide explanations for what happened.
Design/methodology/approach
This paper uses a case study approach to the question of how large financial institutions can go off the rails. Two theoretical perspectives are applied to the cases of the FTX and Celsius collapses. These are the “normalisation of deviance” theory and the “cult of personality”.
Findings
In these two case studies, there is an interaction between the “normalisation of deviance” on the institutional level and the “cult of personality” at the level of individual leadership. The CEOs of the two companies promoted themselves as eccentric but successful examples of the visionary tech finance genius. This fostered the normalisation of deviance within their organisations. Employees, investors and regulators allowed criminal and highly financially risky practices to become normalised as they were caught up in the attractive story of the trailblazing entrepreneur making millions in the new cryptoeconomy.
Originality/value
This paper makes a contribution both to the case study literature on economic crime and to the development of general theory in economic criminology.

Abstract
Purpose
This study aims to propose a research model that emphasizes the moderating influence of ethical leadership (ELS) and the link between socially responsible human resource management (SRHRM) and leaders’ eco-helping behavior (LEH) in the aviation industry.
Design/methodology/approach
The authors used a time-lag research design. Data were gathered from 397 respondents working for aviation companies in Vietnam and analyzed using SmartPLS 4.0.
Findings
The findings show that SRHRM has a beneficial effect on LEH through employees’ voluntary workplace green behavior (EVB). Based on social cognitive theory, this study developed a theoretical model of how SRHRM influences LEH through EVB. The authors discovered that SRHRM increased LEH and that EVB mediated this favorable relationship. Furthermore, the results demonstrate that ELS mitigates the indirect impact of SRHRM on LEH via EVB.
Research limitations/implications
Future studies should assess constructs with numerous observations across time, with a larger sample size and in different industrial settings.
Practical implications
Volunteerism is one of the most important values in the aviation industry given that it is vulnerable to practices such as overbooking, delaying, postponing flights and pressure weather.
Originality/value
This study emphasized the impact of SRHRM and ELS on LEH while fulfilling their professional obligations. EVB may be best positioned to mediate the relationship between SRHRM and LEH.

Abstract
Purpose
The study aims to evaluate how different types of assurors and investors’ Big Five personality traits affect the relationship between levels of assurance for Greenhouse Gas (GHG) reporting and individual investors' decision-making in social responsible investment (SRI).
Design/methodology/approach
This study adopted an experimental approach with 315 individual investors as participants.
Findings
The results show that there are some differences in the individual investors’ decision-making. Accountants are the preferred assuror. Type of assuror and level of assurance for GHG reporting affect investors’ decision-making, in the presence of different levels of investors’ personality traits, extraversion, openness, conscientiousness and neuroticism. However, individual investors with different levels of agreeableness do not have similar influence.
Originality/value
This study extends the literature on individual investors’ decision-making in socially responsible investment by examining the combination of the type of assuror, level of assurance and investors’ personality traits. This study also observes three different assurors, accountants, engineers and specialists and four different assurance levels – reasonable, hybrid, limited and not specified.

Abstract
Purpose
Individual happiness at the workplace allows hospitality organizations to foster an optimistic work environment and endorse the well-being of their employees, which is essential for achieving long-term success. While ethical leadership has been verified as an interpreter of happiness, however, enhancing employee happiness at work remains a gap. The current study seeks to fill this gap by utilizing a multilevel model of the direct and indirect relationship between ethical leadership and happiness at work and also the mediation of group diversity in this relationship.
Design/methodology/approach
The study involved a cross-sectional study with a quantitative methodology. The authors collected data from 36 Jordanian hospitality teams. A total number of 960 participants were selected using the convenience sampling method. The model of the study was validated by multilevel structural equation modeling, and the hypothesized relationships were tested using SPSS 26.
Findings
Results showed that ethical leadership directly promoted happiness and indirectly through group diversity. Moreover, group diversity was found to mediate this relationship.
Practical implications
Findings propose that leaders within hospitality organizations can attain happiness at work by showing more ethical leadership. Practitioners within the hospitality industry likewise ought to recognize that promoting altruistic attitudes among followers is capable of guiding ethical leadership into happiness at work. Moreover, building a developmental culture is crucial for hospitality teams to reinforce the impact of ethical leadership on happiness at work.
Originality/value
The current study magnifies the leadership-happiness research by unlocking both the direct as well as indirect links, the mediation effect, between ethical leadership and happiness at work.

Abstract
Purpose
Achieving sustainable construction is immensely challenging in developing economies due to their inadequate technical support system(s) (TSS). Hence, this article develops a TSS framework for sustainable construction indicators for Zimbabwe, a developing country.
Design/methodology/approach
A post-positivist philosophical stance and deductive reasoning were adopted to test pertinent theory. Construction professionals in consultancy, construction companies, government bodies and academic institutions participated in an online questionnaire survey. Primary data was analysed using a reliability test, Shapiro Wilks test, Kruskal–Wallis H test, mean score ranking, normalisation value, factor analysis and fuzzy synthetic evaluation (FSE).
Findings
FSE revealed a framework with six critical technical support subgroups, in order of importance viz: innovation for construction sustainability; adequate sustainability expenditure and skills training support; adequate project economic assessment and governance support; adequate circularity and environmental technical support; climate change literacy and supplier assessment support; and adequate decent work support. Existing sustainable construction initiatives can be buttressed by strengthening the six identified TSS through related policy initiatives.
Originality/value
The framework developed constitutes an innovative TSS for Zimbabwe to achieve sustainable construction.

Abstract
Purpose
This study aims to develop a proprietary indicator to measure the digital presence of the institutions: the digital presence index.
Design/methodology/approach
This research delves into how nonprofit institutions, specifically business interest associations (BIAs), have developed their internet presence by applying essential digital marketing techniques. To this end, and using big data mining tools, this study analyzes the tracking by internet users of 102 BIAs, with their respective websites in 36 countries in Europe and the USA. In addition, the presence and activity of the institutions included in this study on social networks are considered.
Findings
This research serves as a basis for discussing the current gap between social reality and the digitalization of institutions. In this sense, conclusions are drawn on the importance of managerial profiles in decision-making on digitization and the necessary knowledge that, together with Web and social network managers, they must have to articulate the means and techniques that promote the internet presence of the organizations they manage.
Originality/value
Conclusions are drawn according to the geographical scope of the BIAs, and an argument is made about the difficulties of connection and loss of prominence of this type of institutions among their different target audiences, especially among the youngest and most digitized.
