Abstract

In this paper, we present Dynamic Re‐keying with Key Hopping (DRKH) encryption protocol that uses RC4 encryption technique to ensure a strong security level with the advantage of low execution cost compared to other IEEE 802.11 security schemes. Low computational complexity makes DRKH suitable for solar‐ and battery‐powered handheld devices such as nodes in Solar ESS (Extended Service Set) and wireless sensor networks. Our design goal is to eventually integrate DRKH with different emerging wireless technologies. However, in this paper, we will focus on the integration of DRKH with 802.11 standard since it is the most widely deployed wireless technology. The results and analysis show that DRKH overcomes all the security threats with Wired Equivalent Privacy (WEP) protocol while consuming a much lower power than WEP, Wi‐Fi Protected Access (WPA) 1.0 and WPA 2.0.

Abstract

Purpose

This study aims to explore the pandemic's opportunities for enhancing the environmental practices of the food and beverages green supply chains and its effect on the supply chains' viability by exploring the relationship between fear and uncertainty of COVID-19, food and beverages green supply chain management (F&B-GSCM) and supply chains’ viability based on the two dimensions (robustness and resilience) and examine the moderating effect of innovative technology adoption like big data analysis (BDA) capabilities and blockchain technologies (BCT) on this relationship.

Design/methodology/approach

This study adopted partial least squares structural equation modeling (PLS-SEM) on a sample of 362 F&B small and medium enterprises (SMEs)’ managers in the Egyptian market for data analysis and hypothesis testing.

Findings

The empirical results show that the fear and uncertainty of the pandemic have a significant positive effect on green supply chain management (GSCM). Also, BDA moderates the relationship between fear and uncertainty of COVID-19 and GSCM. However, BCT do not moderate that relationship. Similarly, GSCM positively affects supply chain viability dimensions (robustness and resilience). In addition, F&B-GSCM significantly mediates the relationship between fear and uncertainty of COVID-19 and supply chain viability dimensions (robustness and resilience).

Practical implications

Food and beverages (F&B) managers could develop a consistent strategy for applying BCT and BDA to provide clear information and focus on their procedures to meet their stakeholders' needs during COVID-19. Governments and managers should develop a consistent strategy to apply food and beverages supply chains (F&B SCs)' green practices to achieve F&B SCs' resilience and robustness, especially during the pandemic.

Originality/value

The Egyptian F&B SCs have been linked directly with many European countries as a main source of many basic food and agriculture products, which have been affected lately by the pandemic. Based on the “social-cognitive,” “stakeholder” and “resource-based view” theories, this study sheds light on the optimistic side of the COVID-19 pandemic, as it also brings the concepts of F&B-GSCM, SC resilience, SC robustness and innovative technologies back into the light, which helps in solving F&B SC issues and helps to achieve their viability.

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

This paper analyses the role of green human resources management (GHRM) practices on the application of logistics social responsibility (LSR) practices and examines the moderating effect of big data analytics (BDA) utilisation levels within these relationships.

Design/methodology/approach

Based on quantitative research methodology using survey data from 404 managers in the logistics service providers (LSPs) industry in the Philippines, PLS-SEM technique was used to test hypotheses formulated in this research.

Findings

Empirical results achieved suggest that GHRM practices have a significant positive impact on LSR. Among all individual GHRM practices, green training and development did not have any influence on LSR. While the results also revealed that BDA assimilation acts as a moderator of the relationship between GHRM and LSR, no support was found for the moderation effect of BDA acceptance or adoption on this relationship.

Originality/value

The study fills a gap in the logistics literature by introducing dynamic capabilities theory to the nexus between GHRM and SLR for the first time, which reveals previously unknown answers on effects of GHRM practices on LSR. The study also introduces BDA assimilation as an important moderator that can strengthen positive impact of GHRM on LSR.

Abstract

Purpose

The purpose of this research is to determine how supply chain management (SCM) might be less affected by COVID-19 by using innovative technologies such as the Internet of Things (IoT), eco-friendly corporate practices and other digital advancements. It strongly emphasizes the use of technology to improve supply networks’ and Omani firms’ performance.

Design/methodology/approach

Using a mixed-methods research strategy, this study integrates both qualitative and quantitative approaches. It involves a survey and interviews with supply chain and IT managers from various industries in Oman to gather data and evaluate the impact of technology on SCM.

Findings

This study finds that IoT capabilities, smart technologies (STs) and green practices significantly mitigate COVID-19 impacts on SCM. The performance of the supply chain and the business are both improved by these technologies’ positive effects on integrating various supply chain elements, such as suppliers, internal processes and customer relations.

Research limitations/implications

The main constraint of this study is its concentration on businesses in Oman, potentially restricting the applicability of its findings to broader contexts. Future studies could investigate similar frameworks across various geographic and industry settings.

Practical implications

The findings suggest that incorporating STs into SCM is crucial for enhancing operational efficiency and resilience against disruptions such as COVID-19. This offers valuable insights for managers and policymakers in adopting technology-driven strategies for SCM.

Social implications

This study highlights the significant role of technology in sustaining supply chains during pandemics, thereby supporting economic stability and societal well-being. It underscores the importance of technological advancements in maintaining supply chain continuity in challenging times.

Originality/value

By empirically examining the effect of emerging technologies on enhancing SCM in the context of the COVID-19 pandemic, specifically in the Oman market, this research makes a unique contribution to the body of knowledge.
