Abstract
Purpose
Business environment, which is described by being volatile, uncertain, complex and ambiguous, forces organisations to innovate their products, processes and services to stay competitive. Employees’ innovative behaviours play a critical role in enhancing business environment. Therefore, this study aims to investigate the impact of supervisor’s practices on employee’s innovative behaviour and the mediating role of employee engagement on the relationship.
Design/methodology/approach
A quantitative research design was used. Data is collected from 163 employees from Ministry of Education in Oman by using an online questionnaire. SmartPLS-based structural equation modelling and process macro by Hayes are used for data analysis.
Findings
Results revealed significant relationships between supervisor’s practices (recognition, empowerment and development), employee engagement and innovative behaviour. It also revealed a significant relationship between supervisor’s practices (recognition, empowerment and development) and employee engagement. Furthermore, the results supported the hypotheses that supervisor’s practices affect innovative behaviour through employee engagement.
Originality/value
Although the literature reveals that supervisor’s practices foster innovative behaviour, the mediating role of employee engagement has rarely been empirically investigated. To the best of the authors’ knowledge, this paper is one of the first papers that asserts the importance of employee engagement in mediating the relationship between supervisor’s practices and employee innovative behaviour. It also investigates a hybrid of organisational (supervisor’s practices) and individual level factors (employee’s engagement) in predicting innovative behaviours. It contributes to a more comprehensive understanding of the ways to achieve a business strategy of innovation.

Abstract
Purpose
This study aims is to investigate the correlation between tribological and mechanical properties of the fused filament fabrication 3D-printed acrylonitrile butadiene styrene (ABS) pin with different internal geometries.
Design/methodology/approach
The tribological properties were determined by a dry sliding test with constant test parameters, while the hardness and modulus of elasticity were determined by microhardness and compression tests.
Findings
Although the internal geometry of the pin sample slightly affects the coefficient of friction (COF) and the wear rate of the 3D-printed ABS, it was important to design a lightweight tribo-component by reducing the material used to save energy without compromising the strength of the component. The COF and wear rate values are relatively dependent on the elastic modulus. A 3D-printed ABS pin with an internal triangular flip structure was found to have the shortest run-in period and the lowest COF with high wear resistance. Abrasive wear and delamination are the predominant wear mechanisms involved.
Research limitations/implications
The findings are the subject of future research under various sliding conditions by investigating the synergistic effect of sliding speeds and applied loads to validate the results of this study.
Originality/value
The internal structure affects the mechanical properties and release stress concentration at the contact point, resulting in hypothetically low friction and wear. This approach may also reduce the weight of the parts without scarifying or at least preserving their preceding tribological performance. Therefore, based on our knowledge, limited studies have been conducted for the application of 3D printing in tribology, and most studies focused on improving their mechanical properties rather than correlating them with tribological properties that would benefit longer product lifespans.
