Abstract
Purpose
The purpose of this paper is to optimize system redundancy and maintenance intervals of a propane pre-cooled mixed refrigerant (C3MR) liquefaction process on floating liquefied natural gas (FLNG) export platforms.
Design/methodology/approach
The reliability modeling is based on the time-dependent Markov approach. Four different system options are studied, with various degree of redundancy. Failures in the liquefaction system usually lead to shutdown the whole LNG production plant. The associated shutdown cost is compared with the cost of introducing redundancy and the cost of onboard maintenance. To ensure a high profitability, a model for maintenance optimization is utilized and applied to the main unit of the C3MR liquefaction system to minimize the onboard maintenance cost.
Findings
The results indicated that the introduction of a second liquefaction system (as a standby unit) is the best option for liquefaction plant in terms of reliability and cost. This will substantially reduce the unavailability from 14.7 to 2.19 percent of the total operational hours. Based on the presented system configuration, the annual system profit will increase by 180 million USD if the redundancy is implemented on FLNG export ships. The optimum maintenance intervals of major process components are also calculated to minimize the total cost of maintenance.
Originality/value
The originality of this paper lies within the context in investigating the reliability of the C3MR liquefaction system on LNG floating export terminals using Markov modeling for the first time.

Abstract
Purpose
The purpose of this paper is to make a numerical analysis on unsteady analysis of natural convection heat and mass transfer to obtain flow field, temperature distribution, and concentration distribution.
Design/methodology/approach
A finite element method is applied to solve governing equations of natural convection in curvilinear-shaped system for different parameters as thermal Rayleigh numbers (103=RaT=106), inclination angle (0°=φ=60°) and Hartmann numbers (0=Ha=100).
Findings
Both magnetic field and inclination angle can be used as control parameter on heat and mass transfer. Flow strength decreases almost 100 percent between Ha=0 and Ha=100 on behalf of the higher values of thermal Rayleigh number.
Originality/value
The originality of this work is to application of magnetic field on time-dependent natural convection flow, heat and mass transfer for curvilinear geometry.

Abstract
Purpose
Due to augmented reality (AR) technology improvements, the retail industry has embraced smart retailing as its primary business model. Therefore, organizations must comprehend the intricacies of AR adoption to persuade clients to adopt this revolutionary technology effectively. Thus, the current study proposes and evaluates a comprehensive model that includes unified theory of acceptance and use of technology (UTAUT2), privacy concerns, physical risks and technological anxiety to predict customers’ intention to use AR apps in the retail industry in the Egyptian context.
Design/methodology/approach
The current study examines 398 responses from Egyptian shoppers using partial least squares structural equation modeling (PLS-SEM). Snowball sampling was employed in the existing study. The participants were selected using a “self-selection” strategy, which is an excellent method for research investigations in which the participants freely participate.
Findings
Consumers’ intentions to use AR apps in retail settings are positively impacted by task-technology fit, performance expectation, effort expectancy, social influence, facilitating conditions and hedonic motivation. Conversely, privacy and physical risks negatively affect customers’ intention to use AR apps in retail. Furthermore, technological anxiety serves as a moderator factor in these connections.
Originality/value
To the best of our knowledge, the current study is considered the first to test the role of UTAUT2, privacy and physical risks on users' behavioral intentions toward adopting AR apps in retail. It also examines technological anxiety as a moderator in the retail setting.

Abstract
Sustainability performance of the global trade as well as of the traded products are affected by the trade policies and trade tariffs. Trade tariffs and policies can either encourage or discourage trade among the countries affecting feasibility of trade. In other words, the scope and amount of these trade tariffs have impact on the trade globally. Based on an in-depth literature review, this chapter aims to examine impacts of the trade policies and trade tariffs on the environmental footprint of the global trade. With this aim, recent trade policies and trade tariffs as well as roles of the trade policies, trade tariffs in reducing environmental footprint of the global trade are examined. It arrives at the conclusion that trade tariffs can affect environmental footprint of the global trade as well as of the traded products. They can have impact on the feasibility of the trading activities influencing their profit margins and costs. Based on these findings, recommendations for trade policies and trade tariffs are thereby provided to enhance sustainability performance of the global trade.

Abstract
Geotechnologies have a long tradition in several areas of society and research. The recent development of the ‘Internet of Everything’ (IoE) and Geographic Information Systems (GIS) technologies opened several doors to the contribution of tourism. Emergent technologies contributions to tourism and planning such as web mapping, augmented reality (AR), crowdsourcing and crowdsensing are relatively recent, and there is a lack of research around their potential for Creative Tourism enhancement. For example, combining web mapping with AR or storytelling can be an excellent contribution to operators, planners and tourists. For research purposes, new opportunities are open, particularly by integrating community-shared data. It is well known for the popularity of social networks, the exponential growth of photo sharing, but few studies have been implemented to understand their contribution to research. This chapter focuses on emerging geotechnologies concerning cultural mapping, Creative Tourism and sustainability. Since it is a new growing niche, more research is needed to develop and understand the potential of new approaches. Besides traditional techniques such as quantitative (e.g. surveys) and qualitative ones (e.g. interviews, focus groups and world café), it revises the role of geotechnologies on Creative Tourism development and growing activities. Results from case studies from Europe are analysed.

Abstract
Purpose
The existing literature indicates that the ultimate purpose of green human resource management (GHRM) practices is to enhance sustainable corporate performance by shaping employees’ green behaviors. In this vein, we argue that green organizational culture and employee existing pro-environmental behaviors are the important factors or channels through which GHRM practices shape green employee behaviors for sustainable corporate performance. Consequently, we draw on the ability, motivation, and opportunity (AMO) framework to examine how firms’ GHRM practices indirectly shape employee green behavior for sustainable corporate performance by cultivating and reinforcing green organizational culture under the boundary condition of high employee pro-environmental behavior.
Design/methodology/approach
This study uses multi-source, dyadic, and time-lagged data collected from green HR managers and employees in 242 ISO-14001-certified green firms in the Kingdom of Saudi Arabia. The study applies structural equation modeling through LISREL 12 software for testing of hypotheses.
Findings
The findings support the postulation that GHRM practices, directly and indirectly, shape employee green behaviors for sustainable performance. GHRM practices indirectly enhance employee green behaviors for sustainable performance by cultivating and fostering the green organizational culture in the presence of high pro-environmental behavior.
Practical implications
This study outlines theoretical and practical implications on how HRM managers require an established green organizational culture and employee pro-environmental behaviors to effectively direct GHRM for enhanced sustainable corporate performance. HRM managers should make use of appropriate interventions, including but not limited to GHRM practices, to foster a green organizational culture and employee pro-environmental behaviors.
Originality/value
This is an original study that outlines the importance of alignment between Green HRM practices and employee pro-environmental behaviors towards shaping green organizational culture and employee behaviors for corporate sustainability. The study demonstrates how GHRM practices enhance sustainable corporate performance through sequential mediations of green organizational culture and employee green behaviors, and under the boundary condition of pro-environmental behavior.

Abstract
Purpose
The purpose of this study is to address the global COVID-19 pandemic related to its sustainability, such as environmental, economic and social concerns. The short study also examined how various innovative approaches can help promote sustainable production.
Design/methodology/approach
The methodology examines hypothetical scenarios of the current pandemic and tries to describe the quality of evidence to facilitate careful, critical engagement by readers. Secondary data is used to identify sustainability challenges, such as environmental, social and economic viability challenges. The information in this report was gathered from numerous media outlets, research agencies, policy papers, newspapers and other sources to gain a better knowledge of the issue.
Findings
As a result, most industry executives and policymakers are looking for appropriate strategies and policies to improve their practices and meet consumer demand. The outcomes explore that the COVID-19 pandemic is a central factor in changes in people’s behavior, reflecting sustainability such as environmental, social and economic responsibility. The COVID-19 outbreak, surprisingly, had a bigger effect on sustainable consumption, accompanied by environmental sustainability, and, to a lesser extent, social and economic viability.
Research limitations/implications
Limited secondary evidence and data could not scrutinize the study’s actual problem statements. Hence, it is recommended that the gap in research be fulfilled by conducting a primary survey among various groups of economists, environmentalists and industrialists using the cluster sampling technique by validating the questionnaire of the total sustainable production system. Proposing frameworks for improving the resilience of production and a systematic possible upgraded manufacturing system by using the Industry 4.0 technology during operational processes could advance market demand.
Practical implications
The COVID-19 scenario has compelled manufacturing firms to put their production systems on hold for an extended period while they seek long-term solutions to assure simple delivery and cooperation from both business and consumer standpoints. Various aspects of supply and demand are discussed in the referendum, as well as production and consumption challenges during the COVID-19 era. There is a need to restore the production system and find the right source of raw materials. This work focuses on commodity inventory management systems due to mass production, but due to pandemics, it is not in demand and vice versa. The researcher made comprehensible remarks on the use of digitization in the pandemic, which improves social distancing and social well-being and promotes the production system as well. Besides, manufacturing plants should switch to digital manufacturing to reduce the number of workplaces and hence the risk of an outbreak. Therefore, a better supply chain network is needed to supply more manufacturing units.
Social implications
There is a bright side of coronavirus that the public health crisis raised worldwide has brought many opportunities for governments and society to make eternal reforms in the public health sector door. During restricted movements for fulfilling market demand, the Industry 4.0 technologies for automation, mechanization and digitalization can help significantly advance a company. This technological advancement and computer digitization for the perspective people may improve the environment, economic and social sustainability also increase social media adoption, which can be crucial for agri-businesses to evaluate customers’ behavior and consumption trends.
Originality/value
The paper also instructed to identify critical success factors, barriers and drivers for dealing with the pandemic situation and to develop a strategic policy framework to improve production and process flexibility through the remarkable introduction of digital manufacturing. Before it is too late to stop the spread, producers and consumers must grasp the limits to which suppliers might drive nature.

Abstract
Purpose
This study aims to investigate the influence of requirement engineering (RE) on project performance (PP) in the context of NEOM* in Saudi Arabia. The study also aims to examine the relationship between three components of RE, evolving market needs (ECN), market changes (MC) and technological advancements (TA), on PP, through the mediating influence of effective communication (EC), change readiness (CR) and stakeholder engagement (SE). Further, the study aims to examine the moderating effect of team cohesion (TC) on the RE–PP relationships.
Design/methodology/approach
A research framework is developed by drawing on the resource-based theory and with the support of empirical evidence and rational arguments to propose a set of hypotheses relating to the constructs in the framework. The hypotheses are tested through survey data collected from individual employees working on different projects across NEOM. A total of 336 useable responses were collected that were analyzed through covariance-based structural equation modeling using AMOS v.28.
Findings
The results show although ECN and TA both have a positive impact on PP, MC had no significant relationship with PP. In terms of the mediation hypotheses, EC, CR and SE all partially mediate the relationships between ECN and TA with PP. However, there was no mediating effect in the relationship between MC and PP. Moreover, EC, CR and SE themselves have a significant positive influence on PP. Finally, TC proved to be a significant moderator between ECN and PP and TA and PP, but not in the case of MC and PP.
Originality/value
This study makes three novel contributions. First, most prior empirical studies examined the overall impact of RE on PP; however, the current study provides a more nuanced insight into the relationships between the three components of RE (i.e. ECN, MC and TA) and PP. Second, the mediating roles of EC, CR and SE between components of RE and PP present a finer-grained understanding of how project resources are linked to project success goals through features of the project team. Third, moderating influence of TC with regard to a higher possibility of success for projects are highlighted through this discovery.
