Abstract
Purpose
The purpose of this paper is to present the development of a cost-effective acrylonitrile butadiene styrene (ABS)-rice straw (RS) composite filament for use in fused deposition modelling (FDM) and the effect of RS content on the mechanical properties of the developed filament.
Design/methodology/approach
RS and ABS were processed and mixed at varying fibre content (5-15 per cent). Filament using each mixture was produced using a single screw extruder. Tensile, flexural and water absorption specimens were prepared using a FDM machine. The mechanical properties were then tested following ASTM standards. Scanning electron microscope images of the specimens were also taken.
Findings
Tensile properties decreased as the RS content increased. However, specimens with a 0° raster angle showed better tensile properties than the 45° raster angle specimens, indicating that tensile properties of FDM parts are anisotropic. Flexural properties decreased as fibre content increased but increased at 15 per cent fibre content. Water absorption of the composite increased as the fibre content increased.
Originality/value
This paper highlights a new method of disposing of rice straw waste, by producing an ABS-RS filament for FDM. The resultant filament is cost-effective and can be used to produce cheap prototypes. This paper is the first that studies ABS-RS composites in FDM.

Abstract
Purpose
The purpose of this study is to investigate individuals’ perceptions and behavior when dealing with misinformation on social media platforms. While misinformation is not a new phenomenon, the COVID-19 outbreak has accelerated its spread through social media outlets, leading to widespread exposure to false or misleading information. This exposure can have serious consequences on individuals’ decision-making and behavior, especially when it comes to critical decisions related to education or healthcare. The use of social media as a source of information makes it essential to understand how people perceive and respond to misinformation to develop effective strategies for mitigating its harmful effects.
Design/methodology/approach
This large-scale study explores the Omani individuals’ perceptions and behaviour of misinformation on the social Web in a series of studies that seek to enhance the authorities’ response to misinformation. The study adopted a quantitative approach to collect data. Using WhatsApp as a social networking platform, a survey was disseminated to capture participants’ perceptions and behaviour among different segments of citizens in Oman.
Findings
The findings showed that Omani participants have high verification skills, implying high information literacy skills among them. Additionally, results indicated that misinformation had created doubt and anxiety among the participants. Moreover, it hindered many participants’ ability to take countermeasures and obtain reliable data.
Originality/value
This study was a large-scale study conducted in Oman, making it one of a few studies conducted in the region about perceptions and behaviour towards misinformation. The findings help to understand how different cultures interacted with COVID-19 misinformation. In addition, these findings offer useful insight that can help health information professionals to design preventive resources that help people to obtain accurate information during crises.

Abstract
Purpose
In the present era, the achievement of employee Islamic performance has become a significant challenge for organizations. The purpose of the study is to examine the effect of Islamic leadership on employee Islamic performance directly and indirectly by bridging the connections between employees’ Islamic organizational values, Islamic organizational culture, and Islamic work motivation among the employees of Egyptian banks.
Design/methodology/approach
The authors used quantitative methods in this study and based its findings on the data received from 312 respondents in response to a questionnaire.
Findings
By using SmartPLS 4, this study’s findings demonstrate that Islamic leadership has a positive and significant effect on Islamic organizational values, culture, employee Islamic performance and work motivation. While Islamic organizational values and Islamic organizational culture do not significantly impact employee Islamic performance, Islamic work motivation is a significant predictor of employee Islamic performance. On the one hand, Islamic organizational values and Islamic organizational culture do not mediate the relationship between Islamic leadership and employee Islamic performance. On the other hand, Islamic work motivation is a mediating variable that significantly develops the relationship between Islamic leadership and employee Islamic performance.
Practical implications
The study’s findings support policymakers and human resource management practitioners to develop plans and strategies which enhance the Islamic performance of organizations’ employees. In addition, this study’s findings provide insights for researchers and academicians in developing Islamic leadership within their organizations so that they operate by Islamic values and codes.
Originality/value
Finally, by offering an integrated model of Islamic leadership, Islamic organizational values, Islamic organizational culture and employee Islamic performance, this study’s findings fill the gaps in the context of bank employees in a developing country, namely, Egypt.

Abstract
Purpose
The purpose of this study is to understand the development of social capital in an Arab business environment, and provide an in-depth description of the nature and role of three key Arabic business relationship characteristics (ehsan, et-moone and wasta), their impact on each other and key influencing factors.
Design/methodology/approach
A qualitative research design was used, in which face-to-face semi-structured interviews were conducted with innovation teams (22 team members) at six industrial small and medium-sized enterprises in Saudi Arabia. The interviews were recorded and transcribed, then analyzed (thematic coding) through NVivo.
Findings
The findings suggest that wasta, ehsan and et-moone align closely with the three social capital dimensions (structural, cognitive and relational); thus, developing these three relationship characteristics most likely results in developing social capital. The findings also expand the description of the three business relationship characteristics. Moreover, ehsan, et-moone and wasta appear to influence each other, and are affected by other factors such as an individual’s age and position, and the duration of the relationship. Ehsan has a positive influence on the development of et-moone, while the existence of et-moone appears to be necessary for the establishment of wasta-capital. A high level of ehsan might influence the relationship between et-moone and wasta-use and limit the negative usage of wasta.
Practical implications
International managers can improve the level of ehsan in their organizational and business relationships through assigning incentives and playing the role of moral champion to encourage ehsan behavior. Managers aiming to increase et-moone may choose team members with a high level of ehsan, emphasizing the development of personal relationships, and providing opportunities for socialization both inside and outside the workplace. A high level of ehsan and et-moone will assist managers to develop and use wasta.
Originality/value
This study makes a threefold contribution to the literature. First, it provides an expanded description of the three Arabic business relationship characteristics and how they align closely with the dimensions of social capital. Wasta aligns with the structural dimension and ehsan aligns with the cognitive dimension, while et-moone aligns closely with the relational dimension. Second, it suggests and shows how the three relationship characteristics might interact with each other. Ehsan appears to influence et-moone, and also the relationship between et-moone and wasta. Et-moone appears to have a positive influence on wasta use. Third, the findings also indicate that there might be other factors (e.g. age and position) that influence the interactions between the three business relationship characteristics.

Abstract
Purpose
This paper aims to propose a research model that explores perceived green organizational support (OS) as a mediator of the effect of green human resource management (GHRM) on job performance (JP) and organizational citizenship behavior toward the organization (OCB-O).
Design/methodology/approach
This paper used data obtained from small- and medium-sized hotels in Palestine. The associations given above were tested using structural equation modeling.
Findings
The findings reveal that GHRM boosts hotel employees’ perceptions of green OS. That is, the effective implementation of GHRM is a sign of perceived green OS. Congruent with the study predictions, employees’ perceptions of green OS activate their JP and OCB-O. Finally, perceived green OS mediates the impact of GHRM on JP and OCB-O.
Practical implications
Management should take advantage of green human resource practices to acquire and retain talented employees whose environmental goals and values fit those of the company. Employees should be involved in problem-solving on environmental sustainability and green management. They should also participate in continuous training programs and enhance their awareness of environmental sustainability and green management.
Originality/value
There is a lack of evidence appertaining to the effects of GHRM and perceived green OS on non-green positive workplace performance outcomes. More importantly, there is a scarcity of evidence about the mechanism linking GHRM to these performance outcomes.

Abstract
Purpose
The main objective of this study is to identify the variables influencing consumers' perceptions of sustainable purchasing intentions and the effects such perceptions have on actual sustainable purchasing behavior. This paper aims to develop an understanding of the postmillennial generation's consumption of sustainable products.
Design/methodology/approach
A structured questionnaire was used to collect data for quantitative analysis. It involved sampling a total of 251 respondents, which were postmillennials belonging to the twin cities of Pakistan. A series of tests were applied through Smart PLS4 for all the variables, including descriptive statistics and structural equation modeling.
Findings
The results revealed that there is a significant relationship of social value and electronic word of mouth with digital media usage (DMU). Whereas, link of functional and emotional value with DMU was insignificant. The results also portrayed that there exists a positive link between DMU and sustainable consumption behavior (SCB). Moreover, green purchase intention moderated the relationship between DMU and SCB.
Originality/value
There exists a research gap on the role of postmillennial behavioral regulation and digital media use, as potential influences on their purchase behavior. Despite the fact that digital media has been shown to influence millennials' purchasing decisions in the past, there is still a reluctance among postmillennials to engage in environmentally friendly practices. Consequently, research is necessary to comprehend sustainable consumer behaviors; especially from an unaddressed Pakistani perspective.

Abstract
Purpose
This study aims to explore the determinants that impact state Islamic University/Perguruan Tinggi Keagamaan Islam Negeri students’ intention to adopt online cash waqfs. In doing so, this study integrates knowledge of cash waqf and trust variables within the theory of planned behavior (TPB), allowing an examination of the mediating role of TPB variables and trust within the relationship between knowledge of cash waqf and intention for online cash waqf behavior.
Design/methodology/approach
To carry out an empirical analysis, the authors developed a well-structured questionnaire and distributed it to a group of students currently enrolled in PTKIN, obtaining 443 usable responses. The partial least squares-structural equation modeling (PLS-SEM) technique was used for the dual purposes of data analysis and hypothesis testing.
Findings
This study demonstrates that factors such as attitude, subjective norms, perceived behavioral control, trust and knowledge of cash waqf have a significant and favorable influence on the intention to donate through e-cash waqf. Knowledge of cash waqf impacts attitudes, subjective norms, perceived behavioral control and trust. The final analysis shows that attitude, subjective norms, perceived behavioral control and trust partially mediate the relationship between knowledge and intention in the online cash waqf context.
Practical implications
The aforementioned elucidates the paramount importance of trust in shaping individuals’ tendencies to engage in cash waqfs. The insights mentioned have the potential to be used by cash waqf establishments to promote transparency and accountability, ultimately bolstering the confidence of potential donors.
Originality/value
The concepts of waqf and the use of online cash waqf as a means of donation in developing countries are relatively new. In this study, the intention of students to adopt online cash waqf was predicted for the first time by considering their knowledge of cash waqf and their trust in online cash waqf transactions.

Abstract
Purpose
The purpose of this paper is to examine the direct and indirect effects of demographic factors on employee compensation, job satisfaction and organizational commitment in private higher educational institutes in Bangladesh. Specifically, how do compensation structure and job satisfaction mediate in the link between demographic factors and organizational commitment? To answer this question, a theoretical framework using the theory of employee retention provided by Martin and Kaufman, as its basis was established.
Design/methodology/approach
Data (n = 515) were collected from faculty members of the private universities in Bangladesh. Structural equation modeling was used to analyze the data.
Findings
Findings indicate that though demographic factors have no direct impact on organizational commitment, they have indirect impacts on organizational commitment through the mediation of compensation structure and faculty job satisfaction. Besides, compensation structure also has a significant mediating role in the link between demographic structure and faculty job satisfaction.
Research limitations/implications
One possible drawback is the number of private universities from which the data were collected. In the sample used here, only 20 private universities were selected to conduct the survey. Besides, the study could not include public universities that are also a significant part and parcel of higher education in the country. So, if more private and public universities were taken into consideration to collect the data, the results might be improved. Thus, the usual cautions about overgeneralizing findings from this sample, to populations for which it is not strictly representative, apply.
Practical implications
From a practical perspective, as a cumulative body of work on organizational commitment, we will be better able to advise policymakers and educators on the elements they need to address to increase the longer engagement of the faculty members in their institutes. In this study, the one area of findings that may help policymakers and educators the most concerns compensation package that affects job satisfaction and organizational commitment. We found that demographic factors and compensation packages are the most important factors for the faculty members to impact on organizational commitment in this study.
Social implications
The social implication is that policymakers of the private universities can focus on fair justice in terms of demographic factors and compensation package for job satisfaction, motivation and organizational commitment of the faculty members in their universities.
Originality/value
The findings of the study are important for the policymakers of the higher education institutes.
