Abstract
Purpose
This study aims to investigate the design and optimization of landing gear buffers to improve the landing-phase comfort of civil aircraft.
Design/methodology/approach
The vibration comfort during the landing and taxiing phases is calculated and evaluated based on the flight-testing data for a type of civil aircraft. The calculation and evaluation are under the guidance of the vibration comfort standard of GB/T13441.1-2007 and related files. The authors establish here a rigid-flexible coupled multibody dynamics finite element model of one full-size aircraft. Furthermore, the authors also implement a dynamic simulation for the landing and taxiing processes. Also, an analysis of how the main parameters of the buffers affect the vibration comfort is presented. Finally, the optimization of the single-chamber and double-chamber buffers in the landing gear is performed considering vibration comfort.
Findings
The double-chamber buffer with optimized parameters in landing gear can improve the vibration comfort of the aircraft during the landing and taxiing phases. Moreover, the comfort index can be increased by 25.6% more than that of a single-chamber type.
Originality/value
To the best of the authors’ knowledge, this study first investigates the evaluation methods and evaluation indexes on the aircraft vibration comfort, then further conducts the optimization of the parameters of landing gear buffer with different structures, so as to improve the comfort of aircraft passengers during landing process. Most of the current studies on aircraft landing gear have focused on the strength and safety of the landing gear, with very limited research on cabin vibration comfort during landing and subsequent taxiing because of the coupling of runway surface unevenness and airframe vibration.

Abstract
Purpose
Studies addressing rural residents’ understanding of global warming and their willingness to pay higher prices to mitigate it are very limited. The purpose of this study is to examine the general understanding and attitudes of rural residents in China regarding global warming and their willingness to pay higher prices to mitigate it.
Design/methodology/approach
This study surveyed 1,185 rural residents in three counties of coastal, middle and western China. Multivariate regression analysis was conducted to reveal the relationships between the willingness to pay higher prices to mitigate global warming and influencing factors.
Findings
The majority of respondents had heard of global warming; however, their knowledge of the phenomenon and its causes was very limited. Most respondents admitted the likelihood of risks from global warming. Although most respondents thought they had an obligation to mitigate global warming, only a small percentage of them were willing to pay higher prices to address the problem; the unwillingness of respondents to pay higher prices to mitigate global warming may have been associated with their low income and perceived inability to handle the cost, externalisation of responsibility and causes and lack of knowledge of how to affect it.
Originality/value
This study examines the general understanding and attitudes of rural residents in China regarding global warming and their willingness to pay higher prices to mitigate it. The research is conducive to climate change communications and the implementation of climate policies in China’s rural areas.

Abstract
In 2020, the logistics market in Malaysia was valued at USD 37.60 billion, and it is projected to grow to more than USD 55.0 billion by 2026 at a compound annual growth rate (CAGR) of more than 4%. However, more information is needed about the impact of green logistic practice determinants by the local SMEs on the market share. This study serves as a focal point by examining the factors involved by offering a conceptual framework of determinants and their potential outcomes. This study contributes by demonstrating a conceptual, theoretical framework derived from the synthesis of two theory such as the Resource-Based View theory and the Diffusion of Innovation Theory. At the same time, it offers a holistic approach with an in-depth understanding of the Technological and Organizational factors of SMEs. The relationship between the implementation of green practices and organizational performance is also explored.

Abstract
Purpose
The main goal of this study is to investigate the impact of total quality management (TQM) on the three pillars (economic, environmental and social) of sustainable performance in the Palestinian construction industry. More specifically, it first assesses the current implementation levels of TQM practices and the socio-economic and environmental sustainable performance metrics in the industry. Then, it specifies the correlational relationship between the implementation of the TQM practices and the sustainable performance in the construction industry in Palestine.
Design/methodology/approach
To this end, a quantitative research approach via a self-administered questionnaire approach was adopted, where six TQM practices have been obtained from the Malcolm Baldrige National Quality Award (MBNQA), with some adjustments made in accordance with their importance in the literature review. The targeted population is the construction firms in Palestine, where the data have been obtained from a sample of 66 supervisor engineers working in these firms through a quantitative questionnaire. Regarding the analysis of the conceptual framework and testing the proposed hypotheses, the structural equation modeling (SEM) has been adopted through Smart-PLS software.
Findings
The results indicate a positive and significant relationship between TQM practices and sustainable performance. More specifically, it has been found the levels of implementation of TQM practices and sustainable performance metrics were moderate. Also, it has been revealed that TQM practices positively impact the economic, environmental and social sustainable performance in the Palestinian construction industry.
Practical implications
Investigating the impact of TQM on sustainable performance in this unique challenging context provides a set of valuable implications that extend existing theories and practical guidelines for practitioners and policy makers in the construction industry. More specifically, the study highlights the TQM theory by proving its applicability and effectiveness in conflict-influenced and resource-limited contexts. It also contributes to the sustainable performance theory by integrating the three pillars of sustainable performance in the construction industry in a developing country. Practically, the study offers different stakeholders in this industry with practical actions and insights to facilitate the implementation of TQM to enhance sustainable performance.
Originality/value
This research bridges the gap between TQM and the three pillars of sustainable performance, especially in the construction industry in a developing country context with a unique particularity represented by complicated political instability, never-ending conflict and constrained-resources scarcity and access. This research also supports the TQM advocate’s argument that effective TQM deployment can dramatically improve sustainable organizational performance. Additionally, to the best of the authors' knowledge, this is the first study that addresses the impact of TQM and sustainable performance in the Palestinian construction industry and the one that adopted the PLS-SEM approach for analysis.

Abstract
Purpose
The purpose of this study is to investigate the corrosion inhibition of mild steel alloy in 2 M H3PO4 solution by the pomegranate peel extract as a friendly inhibitor was studied at various temperatures, inhibitor concentrations and immersion times.
Design/methodology/approach
A weight loss method was used to evaluate the corrosion rate. The experimental Taguchi design method was used for the distribution of experiments. The experimental design gave results which were impossible to show graphically. However, this problem was solved effectively with the aid of regression analysis.
Findings
Corrosion rate increased with temperature according to Arrhenius equation. It was found that the efficiency of inhibition was increased with an increase in the concentration of inhibitor and immersion time. However, this diminishes with increased temperature. According to Langmuir isotherm, the inhibitor was adsorbed physically on steel surface. The negative sign of estimated heat of adsorption suggests a stable spontaneous inhibition process. Combination of mathematical and statistical analysis was proposed to demonstrate the results of corrosion rate with high correlation coefficients. In addition, Fourier transform infrared spectrometer examinations confirmed that the organic inhibitor consists of phenolic components as main materials.
Originality/value
Using unconventional approach for evaluation of environmentally friendly inhibitor for corrosion of mild steel in phosphoric acid solution.

Abstract
Purpose
The research investigates the relationship between halal credence, awareness, certification, need for cognition (NC), effort, health consciousness, and satisfaction towards halal food (STHF). In addition, observe the influence of STHF on purchase intention explored. Finally, religiosity is examined as a moderator between STHF and halal purchase intention.
Design/methodology/approach
The data was collected from Muslim participants in Guangzhou and Shenzhen, China. A total of 476 respondents take part in this research. The data was collected from Muslims who eat food from halal food hotels. A purposive sampling technique is used to collect data from respondents. PLS-SEM is followed to test the proposed hypotheses.
Findings
The results reveal that halal credence, awareness, certification, effort, and health consciousness increase STHF. Conversely, NC does not influence STHF. Moreover, STHF significantly determines halal purchase intention. Finally, religiosity strengthens the positive association between STHF and purchase intention.
Practical implications
Food marketers and policy decision-makers can use research findings to enhance halal purchase intention. In China, Muslim customers usually search for halal food by putting in extra effort and seeing halal certification. They trust halal food because religiosity is their priority.
Originality/value
This initial research incorporates halal credence, halal awareness, certification, NC, effort, health consciousness, STHF, and religiosity to examine halal purchase intention using the theory of planned behavior (TPB).

Abstract
Purpose
This study investigates the influence of knowledge hiding in organizations (KHOs), knowledge sharing in organizations (KSOs) and big data knowledge management (BDKM) on knowledge management success. Monitoring (MNT) is used as a moderator between KHO and knowledge management success. Besides, knowledge management success and digital business intensity (DBI) are used to attain competitive advantage (CA). Finally, digital business intensity is used as a moderator between knowledge management success and competitive advantage.
Design/methodology/approach
Data were collected through questionnaires using simple random sampling, and a total of 433 questionnaires were used in the final analysis. Partial least squares structural equation modeling is used to test study hypotheses.
Findings
Results indicate that KSO, BDKM and monitoring are positive, but KHO is negatively related to knowledge management success. Monitoring moderates the relationship between KHO and knowledge management success. Knowledge management success and digital business intensity significantly attain competitive advantage. Digital business intensity significantly moderates the relationship between knowledge management success and competitive advantage.
Practical implications
Top managers can use study findings in decision-making if they want to attain a competitive advantage. KHO has a negative influence on knowledge management success, but this relationship can be changed by monitoring the employees. KSO, BDKM, knowledge management success and digital business intensity play a vital role in determining competitive advantage.
Originality/value
By building knowledge culture using the knowledge-based view, this study contributes to KHO, KSO, BDKM, monitoring, digital business intensity and competitive advantage literature.

Abstract
Purpose
There is currently a lack of comprehensive examination in the research field exploring the relationship between digitalization and environmental performance (EP) in manufacturing small and medium-sized enterprises (SMEs). This study investigates the relationship between digital technologies, digital organizational culture (DOC), environmental dynamism and EP through the mediation of innovation capacity (IC) and moderation of perceived environmental volatility and green strategic intent (GSI).
Design/methodology/approach
The data were gathered from 473 managers of manufacturing SMEs in Pakistan. Partial least square structural equation modeling (PLS-SEM) was applied to examine the mediation and moderation effects. Multiple regression analysis was used to see the influence of digital technologies, DOC, environmental dynamism, innovation capacity, perceived environmental volatility and GSI on SMEs environmental performance.
Findings
Results indicate a statistically significant direct relationship between digital technologies, environmental dynamism and EP. While there is an insignificant direct relationship between DOC and EP. Furthermore, the results reported a significant result between digital technologies, DOC, environmental dynamism and IC. Similarly, IC significantly mediated the relationship between digital technologies, DOC, environmental dynamism and EP. Moreover, results reported that perceived environmental volatility does not moderate the relationship between IC and EP, while GSI significantly moderates between IC and EP.
Practical implications
Policymakers must emphasize advancing digital integration to enhance manufacturing SMEs’ efficiency and environmental effectiveness.
Originality/value
This is the first research that incorporates digital technologies, environmental factors and innovation capacity to measure environmental performance in line of natural resource orchestration theory (natural ROT). All the variables significantly measure environmental performance instead of digital organizational culture. Perceived environmental volatility also does not moderate.

Abstract
Purpose
While there has been a great deal of research to distinguish the factors that promote the adoption of sustainable consumption, however there has been a very little attention given to the contribution of justice, coping appraisal, and psychological distance. The purpose of this paper is to explore the potential role of deontic justice, protection motivation, and construal level theories to elucidate the green purchase intention.
Design/methodology/approach
Data were collected from 471 participants in a laboratory experiment. Then, structural equation modeling was carried out to analyze the data.
Findings
Protection motivation theory is valuable to apply specifically since it introduces the concept of coping appraisal. The findings demonstrate that deontic justice theory (DJT) is a suitable framework that can be employed to shed more light on sustainable consumption. The study shows that consumer can conceptualize a green product at different levels of concreteness or abstraction.
Originality/value
This study is a pioneering effort to look at sustainable consumption within the context of DJT. It departs from the more traditional research by repositioning moral obligation as the primary driver of green purchase intention and by elucidating when green purchase intention is elevated in investigating the moderating role of mindset.
