Abstract
The exponential rise of digital payments has underscored the critical importance of digital payment security, particularly in payment gateway systems. This chapter delves into the vulnerabilities within these systems and proposes a comprehensive security enhancement framework to address them. Recent security breaches, such as those at SONY and Ontario’s birth registry, have emphasised the urgent need for improved protective measures. The proposed framework integrates advanced technologies like data encryption, next-generation firewalls (NGFWs), unified threat management (UTM), network traffic analysis, and multi-factor authentication (MFA). It aims not only to defend against current cyber threats but also to remain adaptable to future vulnerabilities, ensuring the integrity, confidentiality, and availability of transactional data. Moreover, aligning with regulatory standards such as the Payment Card Industry Data Security Standard (PCI DSS) and the General Data Protection Regulation (GDPR) is crucial for building trust and ensuring security in the digital transaction ecosystem. This chapter also highlights the importance of balancing security measures with user experience and advocates for user education and user-centric security solutions. Emerging technologies like artificial intelligence (AI) and blockchain are proposed for real-time fraud detection and maintaining immutable transaction records, offering innovative solutions to contemporary security challenges. Empirical analysis supports the efficacy of the proposed framework, showing improvements in data loss prevention, user satisfaction, and fraud mitigation. This framework, termed ‘Guardians of Trust’, represents a paradigm shift in payment gateway security, providing a scalable and forward-looking model that balances robust security protocols with user experience and compliance considerations. This chapter contributes significantly to the academic discourse on digital payment security.

This paper aims to investigate the prepared modified alkyd and poly(ester-amide) (PEA) resins as antimicrobial and insecticide binders for surface coating applications.
Abstract
Purpose
This paper aims to investigate the prepared modified alkyd and poly(ester-amide) (PEA) resins as antimicrobial and insecticide binders for surface coating applications.
Design/methodology/approach
Salicylic diethanolamine and 4-(N, N-dimethylamino) benzylidene glutamic acid were prepared and used as new sources of polyol and dibasic acid for PEA and alkyd resins, then confirmed by: acid value, FT-IR and 1H-NMR. The coating performance of the resins was determined using measurements of physico-mechanical properties. The biological and insecticide activities of the prepared resins were investigated.
Findings
The tests carried out revealed that the modified PEA and alkyd enhanced both phyisco-mechanical and chemical properties in addition to the biological and insecticide activities. The results of this paper illustrate that the introduction of salicylic diethanolamine and 4-(N, N-dimethylamino) benzylidene glutamic acid within the resin structure improved the film performance and enhanced the antimicrobial activity performance of PEA and alkyd resins.
Research limitations/implications
The modified alkyd and PEA organic resins can be used as biocidal binders when incorporated into paint formulations for multiple surface applications, especially those that are exposed to several organisms.
Originality/value
Modified alkyd and PEA resins based on newly synthesized modifiers have a significant potential to be promising in the production and development of antimicrobial and insecticide paints, allowing them to function to restrict the spread of insects and microbial infection.

Abstract
Supply chain management (SCM) has evolved to fulfill the demands of the dynamic global business environment. The development of the Internet of Things (IoT), which offers unmatched connectivity and real-time data insights, has further transformed SCM. This chapter provides an overview of SCM development and its integration with IoTs. This integration led to improved inventory control, supply chain optimization (SCO), and visibility which further enhances the conventional SCM and provides benefits, such as more accurate real-time tracking and monitoring, improved data analytics, more efficient logistics and transportation management, and reduced costs and wastages. However, despite these benefits, there are various associated challenges and concerns, like privacy and data security, compatibility and interoperability, implementation costs, returns on investment, trained workforce, and training requirements, which are required to be addressed. Additionally, the outcomes of this study and managerial implications are provided along with the future research scope. Overall, this chapter provides valuable insight into the transformative potential of IoT in SCM and practical suggestions on how managers can successfully navigate difficulties and get benefits from the IoT-SCM integration. Organizations can enhance their supply chain operations, efficiency, and innovation by actively confronting challenges and taking advantage of the opportunities provided by IoT technologies. This will ultimately result in the delivery of greater value to both stakeholders and customers.

This study aims to examine the impact of agency cost, Islamic board characteristics and corporate governance on the performance of Islamic institutions.
Abstract
Purpose
This study aims to examine the impact of agency cost, Islamic board characteristics and corporate governance on the performance of Islamic institutions.
Design/methodology/approach
Based on the selected criteria, 92 Islamic banks (IBs) from 20 countries were selected for further research. The authors used generalized method moments (GMM) estimation method. The agency cost and Shariah board characteristics are the explanatory variables. The author uses the age of the bank and the size of the bank for variable control.
Findings
Empirical results indicate that first, agency costs represented by cast/total assets negatively affect IBs’ return on equity and net income. As agency costs rise, IBs’ financial performance declines. Second, Shariah supervisory board (SSB) size and board independence affect IB performance. The study found that SSB size positively affects IB performance.
Research limitations/implications
This research contributes to the literature on IBs in different countries, which policymakers and practitioners can use to improve agency cost functions and Shariah board characteristics. Second, this analysis shows that IBs require specific attention for agency charges, given their operations and business structures. This study contributes to agency theory, which requires Islamic banking information and practices. Finally, the author has aided regulators and IBs by identifying the sources of agency cost practices that can be resolved. The other bank governance contribution is twofold. First, the author studied dual board governance in IBs (SSB and ordinary boards of directors). Second, the author examines how SSB and traditional board governance affect IB performance. This research focuses on banks listed on stock exchanges in the 20 countries analysed.
Practical implications
The research has policy and practical implications for central banks and IBs. By outlining appropriate regulatory guidelines and reporting systems, regulatory authorities can ensure Sharia compliance and protect the independence of IB Shariah department officers. Regulators and relevant stakeholders must ensure Sharia compliance, audits, inspections, reporting and accurate disclosure for IBs.
Originality/value
This paper offers original contributions to professionals in the field of IBs and stakeholders investigating the relationship between agency costs, governance of IBs, characteristics of Islamic supervisory boards and the performance of IBs.

Abstract
Purpose
This paper aims to prepare alkyd protective paint by using modified alkyd with 3,6-dichloro benzo[b]thiophene-2-carbonyl glutamic acid (DCBTGA) as a source of dicarboxylic acid and evaluating their anticorrosive properties compared with those of unmodified alkyd coatings for steel protection.
Design/methodology/approach
Short, medium and long oil alkyds, which represented as (0, 10, 20 and 30% excess-OH) according to the resin constants (Patton, 1962), were prepared through a condensation polymerization reaction via a solvent process in a one-step reaction. The modification of alkyd was carried out by using DCBTGA as a source of dicarboxylic acid. The prepared modified alkyd was confirmed by IR and NMR spectral analysis. The physicochemical, mechanical and anticorrosion performance properties of the considered modified coating formulations against unmodified blank coating were studied to confirm their application efficiency.
Findings
The best results in terms of physicochemical, mechanical and anticorrosion performance properties were found according to the following of this order activity: 30 replacements of the modifier (DCBTGA) for each hydroxyl continent were 30% Ex-OH > 20% Ex-OH > 10% Ex-OH > 0% Ex-OH, compared with that formulation containing unmodified alkyd, especially with increasing the modifier percent.
Originality/value
The prepared DCBTGA-modified resins can be used for different applications based on the type of alkyd and application.

Abstract
Purpose
The present study aims to examine the households’ attitudes and intentions to adopt an indoor air purifier against the smog crisis in India by using a comprehensive theoretical framework based on the combination of the Protective Action Decision Model (PADM) and the Theory of Planned Behavior (TPB). The United Nations Sustainable Development Goals (SDGs) 2030 also emphasized ensuring a healthy and safe life, especially by achieving SDG-3, SDG-11 and SDG-13.
Design/methodology/approach
Using purposive sampling, the data were collected through a survey questionnaire distributed to 382 households, and study hypotheses were assessed by using partial least squares structural equation modeling employing SmartPLS.
Findings
The results revealed that mental health risk perception (MHRP) was the most influential determinant of households’ attitudes toward adopting air purifiers, followed by smog knowledge, physical health risk perception (PHRP), information seeking and product knowledge. Notably, results revealed that households’ attitude is a leading determinant of their adoption intention toward the air purifier compared to subjective norms (SN) and perceived behavioral control (PBC).
Originality/value
To the best of the authors’ knowledge, the present study is the first to provide new insights into an individual’s protective behavior response toward ecological hazards by examining the households’ adoption intention toward the air purifier against the smog crisis using PADM and TPB model inclusively. In addition, the present study analyzes the impact of both PHRP and MHRP on individuals’ protective behavior separately. Also, this study provides theoretical contributions and important practical implications for the government, manufacturers and air purifier sellers.

Abstract
Purpose
The gradual expansion of the tourism sector is raising concerns about whether tourism-based economies are conducive to supporting green growth. Hence, the current study aims to analyze the direct impact of tourism motives on green growth along with the indirect impact of tourism-based economic expansion while controlling for country risk and renewable energy.
Design/methodology/approach
An unbalanced panel data for a sample of 21 countries comprising OECD and non-OECD economies are employed for the analysis.
Findings
Regression results reveal that leisure tourism (LT) significantly and positively influences CO2 intensity compared to business tourism (BT). Propensity score matching results show that the most traveled tourist destinations contribute more to CO2 intensity than those less traveled. Mediation analysis by employing Baron and Kenny’s three-step regression, Sobel’s test and Monte Carlo test shows that tourism-based economic expansion significantly mediates between the nexus of LT and CO2 intensity.
Practical implications
Results of the study provide useful practical implications for sustainable economy and green growth. It recommends to mitigate the challenges of LT, reducing the negative impact and to harness the potential of BT, enhancing the positive influence, through various policies and practices.
Originality/value
This study is the first to examine the impact of LT and BT on green growth, to explore the role of destination popularity and the mediating role of tourism-based economic expansion in this relationship.

Abstract
Purpose
This study examines the impact of various macroeconomic, financial and institutional factors, including foreign direct investment (FDI), financial development (FD), freedom dimensions and institutional sub-systems on CO2 emissions across 30 countries over 23 years (2002–2023). The research aims to uncover both the short-term and long-term effects of these variables on environmental sustainability.
Design/methodology/approach
A Pooled Mean Group – Autoregressive Distributed Lag (PMG-ARDL) model is employed to analyze panel data from 30 countries over the period 2002–2023. The model was selected using the Akaike Information Criterion (AIC) to account for both long-term and short-term dynamics in the relationship between the studied variables and CO2 emissions.
Findings
The results reveal that in the long term, most variables, including FDI, financial development and economic freedom, have significant impacts on CO2 emissions, with varying directions. In contrast, short-term effects are largely insignificant, indicating that the environmental impacts of economic and institutional factors are more pronounced over extended periods.
Research limitations/implications
The findings suggest that policymakers need to consider the long-term environmental consequences of economic and financial policies. For instance, while financial development and economic freedom may drive growth, they also contribute to higher CO2 emissions, necessitating a comprehensive and inclusive approach to sustainable development.
Originality/value
This study provides a comprehensive analysis of the interplay between financial, institutional and freedom dynamics and their impact on CO2 emissions, offering valuable insights for policymakers focused on achieving sustainable economic development. Using the PMG-ARDL model adds robustness to the findings by capturing both short-term and long-term effects.

Abstract
Purpose
The research identifies the factors influencing the satisfaction of clearing and forwarding (C&F) agents in Shuwaikh Port, Kuwait, based on port service quality (PSQ). The research is based on the ROPMIS model to study PSQ. This research adds value to PSQ studies and the need to explore this concept further in the context of Kuwait Shuwaikh port.
Design/methodology/approach
Data were collected from 49 C&F agents using a survey method. A self-administered questionnaire was designed using extant literature. The data are analyzed using SPSS to carry out the validity and reliability, followed by correlation and regression analyses to study the ROPMIS factors on C&F satisfaction.
Findings
The findings indicate that as per correlation analysis, all five PSQ factors are significant with C&F satisfaction. However, the regression results indicate that out of the five PSQ factors, only resources-related PSQ and management-related PSQ are significant towards C&F satisfaction.
Research limitations/implications
This research implies a policy review need for current port operations and emphasizes understanding customer (C&F) expectations. PSQ improvements lead to economic benefits for the country by enhancing the effectiveness of logistics and port management.
Practical implications
The findings promote the need to use technology for improved management, which could enhance Shuwaikh port’s service quality in Kuwait, meet C&F agents' needs and maintain industry competitiveness.
Originality/value
This paper fulfills an identified need to study PSQ in Kuwait government-operated ports to provide better end-user experience and satisfaction.

Abstract
Purpose
Nanofluids are used in technology, engineering processes and thermal exchanges. In thermal transfer processing, these are used for the smooth transportation of heat and mass through various mechanisms. In the current investigation, we have examined multiple effects like activation energy thermal radiation, magnetic field, external heat source and especially slippery effects on a bioconvective Casson nanofluid flow through a stretching cylinder.
Design/methodology/approach
Several studies used non-Newtonian fluid models to study blood flow in the cardiovascular system. In our research, Lewis numbers for bioconvection and the influence of important parameters, such as Brownian diffusion and thermophoresis effects, are also considered. This system is developed as a partial differential equation for the mathematical treatment. Well-defined similarity transformations convert partial differential equation systems into ordinary differential equations. The resultant system is then numerically solved using the bvp4c built-in function of MATLAB.
Findings
After utilizing the numerical approach to the system of ordinary differential equations (ODEs), the results are generated in the form of graphs and tables. These generated results show a suitable accuracy rate compared to the previous results. The consequence of various parameters under the assumed boundary conditions on the temperature, motile microorganisms, concentration and velocity profiles are discussed in detail. The velocity profile decreases as the Magnetic and Reynolds number increases. The temperature profile exhibits increasing behavior for the Brownian motion and thermal radiation count augmentation. The concentration profile decreased on greater inputs of the Schmidt number and magnetic effect. The density of motile microorganisms decreases for the increased value of the bio-convective Lewis number.
Originality/value
The numerical analysis of the flow problem is addressed using graphical results and tabular data; our reported results are refined and novel based on available literature. This method is useful for addressing such fluidic flow efficiently.
