Abstract

Purpose

Because unethical behaviour pervades in organisations, how to inhibit the interpersonal influence of unethical behaviour has become increasingly important. This study aims to integrate the deontic justice theory and affective events theory to examine the relationship between an individual’s unethical behaviour and his or her peers’ vicarious learning by highlighting the mediating effect of peers’ moral anger and the moderating effect of task interdependence on this relationship.

Design/methodology/approach

Data were collected in two waves from 254 employees of a large manufacturing company in the People’s Republic of China.

Findings

The hypothesised moderated mediation model was supported. Specifically, as expected, peers’ moral anger mediated the negative relationship between an individual’s unethical behaviour and peers’ vicarious learning. Task interdependence moderated the direct relationship between the individual’s unethical behaviour and his or her peers’ moral anger and the indirect relationship between an individual’s unethical behaviour and his or her peers’ vicarious learning via the peers’ moral anger such that these relationships were stronger when the level of task interdependence was higher.

Originality/value

This study argues that the deontic justice theory is a supplement for the social learning theory in explaining the interpersonal influence of unethical behaviour. Drawing on the deontic justice theory, this study demonstrates that an individual’s unethical behaviours are unlikely to be rewarded or accepted, and by integrating the theories of deontic justice and affective events, offers a rationale for the emotional mechanism that underlies the interpersonal influence of unethical behaviour.

Abstract

Purpose

This paper aims to report the conductivity measurement of ten different surfactant-free microemulsions (SFMEs)

Design/methodology/approach

The variations of electrical conductivity as a function of water volume fraction are examined at one constant alcohol (or DMF, ethyl lactate, γ-valerolactone)/water, alcohol (or DMF, ethyl lactate, γ-valerolactone)/oil volume ratios for each sample.

Findings

Most of the results are consistent with percolation character. The conductive mechanism of these SFMEs is discussed by the percolation model, and it is found that it might be described with the static percolation model below the percolation threshold.

Originality/value

Our report gives a systematic research on the percolation mechanism of as many species of SFMEs as possible by the theoretical models

Abstract

Purpose

The purpose of this paper is to improve the hydraulic efficiency without changing the overall dimension. The blade profile optimization design of the aero-centrifugal pump based on the biharmonic equation surrogate model has been studied.

Design/methodology/approach

First of all, Bezier curves and linear function are used to control the annular angle distribution and the stacking angle of blade profile under the MATLAB platform. Grid independence analysis has been studied to find the finest mesh scheme. After the precision comparison of test data and computation fluid dynamics 15 sets of design parameters are carried out as the boundary condition of the biharmonic equation. The efficiency surrogate model of the biharmonic equation is constructed via iteratively solving of a discrete difference equation. The other two surrogate models of response surface model (RSM) and radial basis function neural network surrogate model (RBFNNSM) are compared with the biharmonic equation surrogate model by the standard of modified complex correlation coefficient R2 and root mean square deviation (RSME). Finally, the artificial fish swarm algorithm has been used to find the global optimal design parameters with the objective function of highest efficiency.

Findings

The results show that the design parameters code conversion method can reduce the number of optimization parameters from five to three, makes the design space become a cube, and compared with RSM and RBFNNSM, the biharmonic equation surrogate model has higher precision with R2 is 0.8958, RSME is 0.1382. The final optimum result of AFSA is at the point of [1 −1 −1]. The internal flow field analysis shows that after optimization the outlet relative velocity becomes more uniform and the wake effect has been significantly decreased. The hydraulic efficiency of the optimized pump is about 59.45 per cent increasing 5.4 per cent compared with a prototype pump.

Originality/value

This study developed a new method to optimize the design parameters of aero-centrifugal pump impeller based on biharmonic equation surrogate model, which had a good agreement with experimental values within just 15 sets of the original design. The optimization results shows that the method can improve the hydraulic efficiency significantly.
