Abstract
Purpose
This study aims to find out how pomposia fruit powder (Syzygium cumini L.) mixed with roasted coffee (RCO) affected antioxidants, phytochemicals, lipid peroxidation inhibition and sensory attributes.
Design/methodology/approach
Pomposia fruits (Syzygium cumini L.) powder (PFP) was integrated with RCO at levels of 0.0%, 5.0%, 10.0%, 15.0% and 20.0%. RCO, PFP and binary mixtures containing RCO: PFP were evaluated for their total phenolics (TP), total flavonoids (TF), anthocyanin content (AC), antioxidant activity and phenolic compounds fractionation. The oxidative indices of coffee oil samples were measured throughout different storage intervals. Additionally, sensory characteristics of RCO enriched with different PFP doses were evaluated.
Findings
PFP samples exhibited the greatest TP content (1910 mg/100 g), whereas RCO samples had the lowest concentration (1090 mg/100 g). As more PFP was added, the corresponding coffee blends’ concentrations of TP, TF and AC were improved significantly. PFP possesses a radical-scavenging activity that is about 1.20 times more than RCO’s. DPPH (2,2-diphenyl-1-picrylhydrazyl) radical-scavenging activity jumped significantly from 74.13% in control (untreated) samples to 77.64%, 78.39% and 80.15% for samples enriched with 10.0%, 15.0% and 20% PFP, respectively. Significant increases in gallic acid, hesperidine, benzoic acid, chlorogenic acid, hispertin, catechol, quercetin, pyrogallol and rutin were detected when RCO was mixed with different quantities of PFP. At the end of storage trial, the coffee oil treated with 20% PFP had AV, PV and TBA values that were about 1.70, 1.95 and 1.66 times lower, respectively, than those of the control sample that had not had PFP addition. The RCO with 5.0% PFP achieved the greatest over acceptability grades.
Originality/value
To the best of the authors’ knowledge, this study was the first study to evaluate the effect of incorporating various level of pomposia fruit powder into RCO. The findings shows that adding different concentrations of pomposia fruit powder into RCO can indeed enhance the radical-scavenging activity of the coffee and potentially extend its shelf life.

Abstract
Purpose
This study aims to explore the tower crane safety factors (TCSFs) that influence tower crane safe operations (TCSOs) in modular integrated construction (MiC). It evaluates how the adoption of these factors contributes to achieving TCSOs and promoting sustainable practices (SPs) within MiC.
Design/methodology/approach
To achieve this aim, the study employed a systematic search to ensure a comprehensive collection of variables. Additionally, it conducted a questionnaire survey involving professionals and utilized a brainstorming technique to categorize the different variables. Finally, partial least squares structural equation modeling (PLS-SEM) was employed to test the relationship between TCSOs and SPs.
Findings
The results of measurement models indicated strong convergent and discriminant validity, with each observed variable correlating well with its latent variable. Moreover, a significant positive correlation between TCSOs and SPs was evidenced by a path coefficient (β = 0.755) and a p-value of <0.05. Lastly, the structural model revealed that the independent variables strongly influence the dependent variable (i.e. SPs) by 57%, underscoring safety's pivotal role in advancing sustainability within MiC projects. These findings provide empirical evidence that improving tower crane safety can directly enhance sustainable practices, offering a dual benefit of increased safety and sustainability for the construction sector.
Originality/value
This study makes a unique and previously undiscovered contribution to the field by identifying the TCSFs in MiC and employing a novel approach by utilizing PLS-SEM to create a unique mathematical model. It offers valuable insights into the relationship between TCSFs, TCSOs and SPs, thus contributing to methodological advancements within Safety Science and providing a foundation for future research and practical implementation in the construction industry.

Abstract
Nowadays, the main challenge in the higher education is the daunting task of transforming universities into digital era institutions. Improving HE students' competence to meet the flow of technological innovations through DT has been the focus of many countries. This task has imposed the restraint that HE institutions should implement the most effective strategies of DT. This chapter is focusing on how DT strategies play their role in making the transformation itself become germane and give its fruits. Therefore, this chapter presents the most effective DT strategies that can be implemented by HE institutions in order to prepare their students for the existing professional roles in their societies. A good DT strategy is one that connects the organization's current level of digital maturity with its future ambition. The well-known strategies in the DT field are as follows: the strategy of electronic projects, strategy of smart electronic platforms, integrated training strategy, participatory e-learning strategy, smart learning strategy, pervasive learning strategy, microlearning strategy and e-design thinking strategy, in addition to the strategy in which traditional learning methods are combined with e-learning methods. It is worth noting here that the chapter is not an attempt to favor a strategy over another or compare and contrast them to uncover their differences at any level. On the contrary, the writer will work on displaying how each strategy can be implemented in order to accomplish DT in HE instructional practices. Also, this chapter will show how complementary these strategies can be once they are utilized to reach DT.

Abstract
Purpose
Using passive techniques like twisted tapes and corrugated surface is an efficient method of heat transfer improvement, since the referred manners break the boundary layer and improve the heat exchange. This paper aims to present an improved dual-flow parabolic trough collector (PTC). For this purpose, the effect of an absorber roof, a type of turbulator and a grooved absorber tube in the presence of nanofluid is investigated separately and simultaneously.
Design/methodology/approach
The FLUENT was used for solution of governing equation using control volume scheme. The control volume scheme has been used for solving the governing equations using the finite volume method. The standard k–e turbulence model has been chosen.
Findings
Fluid flow and heat transfer features, as friction factor, performance evaluation criteria (PEC) and Nusselt number have been calculated and analyzed. It is showed that absorber roof intensifies the heat transfer ratio in PTCs. Also, the combination of inserting the turbulator, outer corrugated and inner grooved absorber tube surface can enhance the PEC of PTCs considerably.
Originality/value
Results of the current study show that the PTC with two heat transfer fluids, outer and inner surface corrugated absorber tube, inserting the twisted tape and absorber roof have the maximum Nusselt number ratio equal to 5, and PEC higher than 2.5 between all proposed arrangements for investigated Reynolds numbers (from 10,000 to 20,000) and nanoparticles [Boehmite alumina (“λ-AlOOH)”] volume fractions (from 0.005 to 0.03). Maximum Nusselt number and PEC correspond to nanoparticle volume fraction and Reynolds number equal to 0.03 and 20,000, respectively. Besides, it was found that the performance evaluation criteria index values continuously grow by an intensification of nanoparticle volume concentrations.

Abstract
Corporate governance is one of the most important topics available in the literature related to large-sized companies. However, the topic has rarely been discussed in the case of SMEs. However, the importance of the topic and mechanism has been in the limelight for more than one and a half decades. Although lack of knowledge especially regarding theoretical implications, literature and implications is still required to optimize the mechanism as well as its implications for SMEs. Therefore, this chapter has been formulated specifically concerning corporate governance mechanisms and their implications for SMEs. Hence, the scope of this study is much broader than those studies that focused on quantitative examination of variables of interest. Thus, the significance of this study has multiple folds as it is not only important for academicians and researchers but also for managers, entrepreneurs and policymakers.

Abstract
The chapters emphasise the importance of data management from the perspective of the business management process, where big data is the most crucial and pressing technical and business issue in the modern realm of technology. The same data has a significant influence on the current financial environment. Organisations are facing challenges in explicating complicated financial data manually and using it to drive their decision-making processes. Data-driven decision-making is a dominant tool for any professional. It enhances precision, alleviates risk, improves efficacy, aids financial management, offers customer insights, provides a competitive edge, supports strategic planning, enables performance tracking, fosters innovation and has predictive capabilities. The power of data makes the organisation more prosperous and resilient in the face of change. By making informed decisions based on data and analytics, organisations can unlock their full potential and achieve sustainable growth. The chapter suggests a data-driven culture in the organisation with the help of strategising in terms of data collection, analytics and data management by establishing governance and regulatory practices to ensure data security and integrity. The latter part covers the forecasting and transformative ability of data by integrating machine learning and deep learning models. The chapter also covers the visualisation perspective of the data by transforming the information into a visual setting, illuminating the hidden insights and making them tangible and relatable. The chapter closes with a suggestion for managers to stay competitive, make more reasoned and sound decisions and adapt to the evolving business environment.

Abstract
Purpose
Leadership’s dark side has been on the rise, negatively affecting organizations. The phenomenon, however, is not as simple as it seems. Based on social exchange and conservation of resource theories, current research aims to explore the impact of psychological entitlement on despotic leadership, ultimately leading to instigated workplace incivility. Moreover, emotional exhaustion was tested as a mediator and Islamic work ethics as a moderator.
Design/methodology/approach
This study aims to examine the effect of dark side of leadership and for this, the survey approach was used to collect data from 402 bankers from Pakistan’s twin cities (Islamabad and Rawalpindi).
Findings
The results showed that psychological entitlement leads to despotism and despotic leaders become a reason for instigated workplace incivility. Results also showed that emotional exhaustion mediated, and Islamic work ethics moderated the relationship.
Practical implications
Bankers have a demanding job which is further exacerbated by despotic leaders feeling psychologically entitled and instigating employees toward uncivil behaviors as they experience emotional exhaustion. Despotic leaders need to be dealt with to reduce instigated incivility and Islamic work ethics can also aid in improving employee behavior.
Originality/value
Literature available on both antecedents and effects of the leadership’s dark side is limited, and this study strives to contribute by extending the literature available on psychological entitlement, despotic leadership and instigated workplace incivility relationships.

Abstract
Purpose
The purpose of this research is to support the green movement and improve corporate performance by focusing on green intellectual capital and its various components (e.g. green human capital, green structural capital and green relational capital). Furthermore, this study looks into the impact of business reputation in mediating the link between green intellectual capital qualities and business performance.
Design/methodology/approach
To obtain data from the target population, this study employed quantitative techniques and a survey approach for data collection from respondents (managers and employees) of firms. The final sample size was 255.
Findings
According to structural equation modeling green human capital, green structural capital and green relational capital all have a positive and statistically significant impact on organizational performance. Furthermore, the study shows that a company’s reputation plays an important role in mediating the relationship between the green intellectual capital component and business performance. These findings are confirmed by the natural resource-based perspective theory. This shows that developing green intellectual capital and promoting a green environment increases a company’s reputation among stakeholders, which promotes organizational performance.
Research limitations/implications
The study’s findings will help policymakers and administrators better understand the role of green intellectual capital in business reputation and performance. Based on empirical data, the study would contribute to the management, environmental science and performance literature.
Originality/value
To the best of the researcher's knowledge, this is the first study to apply the natural resource-based view theory and to consider corporate reputation as a mediator between green intellectual capital and business success.
