The purpose of this study aims to simulate the long-period fiber grating sensor pulse peak position against the transmission range. The long-period fiber grating sensor pulse peak position against the transmission range is simulated clearly where the pulse peak value at zero position is 0.972655 with the ripple factor of unity. It is demonstrated that the long-period fiber grating sensor bandwidth can be estimated to be 50 µm. Wavelength shift of the long-period grating sensor (LPGS) is reported against grating wavelength, applied temperatures and applied micro strain.

This work has reported the numerical simulation of LPGS transmission spectrum behavior characteristics under the strain and temperature effects by using OptiGrating simulation software. The sensor fabrication material is silica-doped germanium. The transmittivity/reflectivity and input spectrum pulse intensity of long-period Bragg sensor variations are simulated against the grating wavelength variations. Input/output pulse intensity of LPGS variations is simulated against the timespan variations with the Gaussian input pulse from 100 to 500 km link length.

Temperature variation and strain variation of the LPGS are outlined against both applied temperatures and micro-strain variations at the central grating wavelength of 1,550 nm.

Drawing on the reasoned action theory, this study aims to examine the impact of environmental knowledge (EK) and environmental sustainability performance (EP) on environmental behavior (EB) mediated by environmental attitude (ATT). Furthermore, to examine the moderating effect of environmental advertising (ADD) on the indirect relationship between EP and EB, mediated by ATT on the one hand, and EK on EB, on the other hand, mediated by ATT.

The data were gathered within an international context for passengers from North African countries (NAC) (Egypt, Algeria, Tunisia, Libya, Morocco and Sudan) using primary quantitative data from online and self-administered questionnaires. A total of 1,052 questionnaires were collected from passengers who traveled through Egyptian airports. The collected data were analyzed through covariance-based structural equation modeling.

The findings indicated that ATT moderates the relationship between environmental knowledge and behavior. In addition, ATT mediates the airports' environmental behavior and environmental sustainability performance. Moreover, ADD moderates the indirect association between EP and individuals' environmental knowledge and behavior through the mediated effect of ATT.

This research output will help extend the theory’s scope by conceptualizing its abstract ideas using research variables and applying them in NAC countries. This can be a milestone for altering individuals' behavior toward the environment in airports.

This study aims to assist airport authorities in the development of standards for enhancing environmental performance. Enhancing environmental issues is of utmost importance, especially in the context of airports, which have been a subject of significant environmental concern. This study examined the environmental practices of airport passengers in NAC, given their significant role as the primary source of greenhouse gas emissions on the African continent. The present approach has the potential to be utilized in modifying airport conduct and enhancing stakeholder engagement, specifically within the context of NAC.

The objective of this study is to enhance the relationship between nature and humans by endeavoring to modify human attitudes toward the environment. The objective of this initiative is to bridge the current disparity in the socio-environmental connection by fostering environmental consciousness among individuals who utilize airport facilities. The objective will be accomplished by the construction of a theoretical framework that integrates crucial elements acknowledged for their substantial influence on altering human attitudes, thus fostering a greater sense of environmental consciousness and ultimately improving societal well-being.

Since the global supply chain prioritizes environmental transportation systems, this study provides a conceptual framework for airport authorities to develop and create policies to push air passengers' behavior toward environmental practices in NAC.

The purpose of this paper is to empirically investigate the mediating effect of social capital (SC) on knowledge management (KM) and intellectual capital (IC).

A conceptual model of the connections between IC, KM, and SC was developed and the posited hypotheses were tested using a survey data set of 281 questionnaires collected from knowledge workers working in 72 information and communications technology companies operating in Jordan.

The findings show that knowledge documentation and knowledge transfer emerged as having the strongest effects on IC, followed by knowledge acquisition and knowledge creation, while knowledge application was found to have an insignificant effect. Also, knowledge transfer and knowledge acquisition emerged as the only two significant processes for the development of SC. Moreover, SC was found to partially and significantly mediate the effects of all processes on IC.

To promote the development of IC, particularly, in a knowledge-intensive business service (KIBS) sector, documentation, transfer, acquisition, and creation of knowledge are especially effective processes. Furthermore, SC can be significantly enhanced through ensuring effective internal knowledge transfer and acquisition practices. Nurturing IC in a knowledge-intensive context can also be significantly enhanced through looking at the firm as a cooperative knowledge-sharing entity, i.e. investing in SC.

This is the first empirical study that has examined the links among KM processes, SC, and IC in a KIBS sector within an “oil-poor,” “human resource-rich” Arab developing country context.

Having Middle Eastern tourism industry as the context, this study aims to examine the impact of the four main dimensions within service innovation (i.e. product, process, organizational and marketing innovations) on tourist satisfaction; subsequently, towards the development of destination loyalty. Realized that religiosity prevails as an important social force that shapes individual behaviours, this study, hence, placed further assessment upon its moderating role, specifically in the relationships between tourist satisfaction and destination loyalty.

With adopting the approach of self-structured questionnaire, 214 usable responses had been collected for this study. Obtained data was then analyzed by conducting exploratory factor analysis, confirmatory factor analysis and multiple linear regression analysis through the usage of structural equation modelling.

Analysis of obtained data has revealed all the investigated dimensions within service innovation as active predictors to tourist satisfaction, with the exception of product innovation, while having marketing innovation being of highest significance. In turn, tourist satisfaction is found to greatly influence the formation of destination loyalty. Findings then provide notable indication on religiosity as a moderating factor to the proposed relationships within the investigated framework, between service innovation and tourist satisfaction, as well as tourist satisfaction and destination loyalty.

This study, thus, revealed the level of religiosity, particularly from the standpoint of Islamic perspectives, in playing a critical role towards predicting capability of service innovation on tourist satisfaction, and further, destination loyalty. Contributions hereby lie on theoretical and pragmatic insights concerning aspects of service and Islamic marketing within today’s tourism front.

The recent Middle East war and the subsequent strengthening of political ties between the United States and Middle Eastern countries have opened the doors to attractive business opportunities and increased the chance for the transferability of Western business practices more than ever before. The objectives of this study were to examine marketing practices among Egyptian firms. The results from 51 firms operating in various sectors of the Egyptian economy indicate a massive neglect and absence of modern marketing practices among the surveyed firms. Foreign firms that adapt their strategies to cultural and structural impediments to marketing in that country will prove most profitable.

In recent years, the global focus has increasingly shifted toward the adoption of electric vehicles (EVs) due to growing concerns about environmental sustainability and the imperative of reducing greenhouse gas emissions. The transportation sector, a significant contributor to air pollution and climate change, faces increasing pressure to embrace EVs as a solution. However, the resistance exhibited by customers toward adopting new technology poses a substantial obstacle to the widespread adoption of EVs. Drawing on the link between theory of reasoned action (TRA) and self-congruity theory, this research aims to determine the factors that affect the customer intention toward EV.

The research conducts a questionnaire collecting 950 respondents from the Egyptian market. The research used primary quantitative data from online and self-administered questionnaires.

The findings indicated that green trust, price sensitivity and reliability have a positive impact on customer’s intention. However, self-image congruence was not affecting customer intention. For the moderating role of financial self-efficacy, it is affecting the relationship between price sensitivity and customer’s purchase intentions toward EV.

This research will expand the theory by conceptualizing its abstract notions through research variables and implementing them in the Egyptian market. Furthermore, it links the two distinct theories. This knowledge can be utilized by policymakers and stakeholders to expedite the adoption of EVs in the Egyptian market.

This study presents a conceptual framework for managers and policymakers about the factors that affect the customer to buy EVs, since the international organizations emphasize eco-friendly transportation systems.

This paper sought to examine the factors that influence intention to recommend, focussing on the extension of the theory of planned behaviour in halal tourism, with additional instruments such as halal safety and security, and trustworthiness of halal information.

Guided by a quantitative approach, cross-sectional data were collected using 394 Muslim diaspora tourists. The analysis technique used in this study is the partial least square structural equation modelling (PLS-SEM).

The results suggest that halal planned behaviour may account for the intention to recommend. Halal attitude, subjective norm, halal image, halal value, halal safety and security, and trustworthiness of halal information positively and significantly affect intention to recommend.

Muslim diaspora tourists are identified to have halal planned behaviour on intention to recommend. Hence, destination managers and practitioners are suggested to develop proactive halal products and services that appeal to tourists' intention to recommend.

This study has developed two new constructs: halal safety and security, and the trustworthiness of halal information grounded on the theory of planned behaviour in halal tourism. Specifically, the focus is on Muslim diasporic tourists' perspective in a non-Islamic context.

Reverse logistics (RL) activities are becoming crucial in today’s business environment because of their ability to enhance organizational capabilities to manage waste and resources effectively and efficiently as an approach for achieving sustainability. These capabilities can eventually create sustainable competitive advantage (SCA). Drawing on resource-based view (RBV), this study posits RL as a tool to develop capabilities gained from high performance (financial and nonfinancial) to enhance SCA.

Covariance-based structural equation modeling (SEM) was used to analyze 1,207 responses collected from manufacturing organizations operating in Egypt. Data were gathered through an online survey sent via email to manufacturing organizations operating in Egypt, particularly Cairo, Giza and Alexandria, as these governorates contain most business activities in Egypt and hence high a percentage of waste.

Results indicated that RL activities (recycling, remanufacturing, repair, recondition and disposal) can fully mediate the relationship between organizational performance (financial and nonfinancial) and SCA. However, the remanufacturing and recycling mediating roles between financial performance and SCA were not significant.

Applying this research in a developing country (Egypt) will help extend RBV and incentivize organizations to apply RL activities, which can potentially solve several environmental issues such as decreasing waste.

Using the research variables in combination will help in filling the literature gap as previous research focused on RL and only organizational operational performance, where RL was used as an independent variable with no illustration of how its dimensions affect performance or its mediating role between performance and SCA.

Due to the rapid increase in environmental degradation and depletion of natural resources, there has been a recent shift in global focus from economic concerns to environmental ones. The purpose of this research is to examine the relevant literature on the use of blockchain technology to promote environmental sustainability through customer integration.

The proposed framework is based on the theoretical lens of systems theory (ST) and knowledge-based view (KBV) theory, and is developed by conducting a systematic literature review of 51 articles, (16) from 2022, (17) from 2021, (10) 2020, (5) 2019, (2) 2018 and (1) from 2017 on blockchain technology (BCT), environmental supply chain performance (ESCP) and customer integration.

Three main propositions are formulated and demonstrated using the developed framework, which shows that BCT has the potential to revolutionize the supply chain from an environmental sustainability perspective through facilitating waste management, reduction of energy consumption and reduction of carbon emissions/pollution. The technology will not only enhance the environmental sustainability but also facilitate customer integration through resolving transparency issues, protecting data/enhancing security, database decentralization, promoting trust and immutability.

The effects of blockchain on supply chain performance has been studied in the past; however, no studies were found which shed light on how BCT can affect ESCP through the mediation of customer integration.

This paper aims to examine the moderated mediation effect of the lack of students’ socialization (as one of the COVID-19 consequences) and the university reputation on the relationship between the service innovation and students satisfaction. The relationship between students satisfaction and their loyalty is also examined.

This study adopts a quantitative research approach, whereas the study population consists of all universities’ students in Lebanon. Data were collected from 201 students, elected depending on snowballing sample technique. A questionnaire was used to gather data, whereby partial least squares structural equation modeling was used to check the proposed scales validity and the relationships between the study variables.

The findings reveal a significant direct effect for university’s service innovation on students satisfaction and an indirect effect through the mediation role for university reputation. Moreover, an evidence for weak negative significant effect for lack of socialization on students satisfaction exists. Whereby, lack of socialization does not moderate the relationship between university service innovation and students satisfaction. Finally, students satisfaction has a significant positive effect on their loyalty.

This paper advances the service innovation literature in the higher education sector. In addition, the paper might be the first paper to address the influence of lack of socialization as one of the COVID-19 consequences on students satisfaction. Furthermore, areas for future research are suggested.
