Purpose
The purpose of this study is to reveal the mechanism of peer abusive supervision on bystander behavior based on the perspective of bystander from two different paths of bystander empathy and bystander hostility toward supervisor. At the same time, it discusses the moderation effect of bystander traditionality on the two paths.
Design/methodology/approach
This study conducted a three-wave longitudinal survey. The data were collected from 454 employees and their coworkers in several Chinese enterprises. The authors used Mplus 7.4 and adopted a bootstrapping technique in the data analysis.
Findings
Peer abusive supervision leads bystanders to empathize with the abused colleague and thus exhibit more organizational citizenship behaviors, and peer abusive supervision also induces bystanders to develop hostility toward the abusive supervisor and thus produce more workplace negative gossip behaviors. In addition, it is found that bystander traditionality has a moderation effect in the process by which peer perceptions of abusive supervision influence bystander empathy and bystander hostility.
Originality/value
Based on Affective Events Theory, this study explores the mechanism of colleague perception of abusive supervision on bystander behavior from a bystander perspective. The results of this study not only provide a more comprehensive expansion of the weighting factors in the influence mechanism of abusive supervision but also provide new ideas for organizations to reduce the negative effects of workplace abusive behaviors.

Abstract
Purpose
The purpose of this research is to investigate how generalisable the public service motivation (PSM) observed in Western society is to China and to examine the effects of public service motivation on job satisfaction.
Design/methodology/approach
Exploratory factor analysis and confirmatory factor analysis techniques are applied to survey data of 191 public servants in China to investigate the generalisability of Western PSM. Using hierarchical regression analysis, the paper examines the effects of the dimensions of PSM on job satisfaction.
Findings
The results show that the public service motivation observed in the West exists in China, but the generalisability of the construct is limited. Three of the four dimensions of public service motivation (attraction to public policy making, commitment to the public interest, and self‐sacrifice) exist in China, but the fourth dimension (compassion) is unconfirmed.
Originality/value
The paper is the first to examine the generalisability and instrumentality of PSM as observed in Western society to China. The results indicate that the public service motivation observed in the West also exists in China, but that the generalisability is limited. Public service motivation emerges from the results as a positively significant predictor of job satisfaction in the public sector of China. It enhances the applicability and meaningfulness of the concept of public service motivation across political and cultural environments.

– The purpose of this study is to empirically test and extend knowledge of the effects of emotional labor of frontline service employee.
Abstract
Purpose
The purpose of this study is to empirically test and extend knowledge of the effects of emotional labor of frontline service employee.
Design/methodology/approach
The authors examined the effects of emotional labor (surface acting and deep acting) on frontline employee creativity, as well as the mediating effects of different kinds of job stress (hindrance stress and challenge stress) on the relationship between emotional labor and creativity. The research hypotheses were tested using data collected from 416 service employee–supervisor dyads in 82 Chinese local restaurants.
Findings
Results show that surface acting is negatively related to and deep acting is positively related to frontline employee creativity; surface acting is positively related to hindrance stress, while deep acting is positively related to challenge stress; and hindrance stress mediates the relationship between surface acting and creativity.
Originality/value
This study extends the consequences of emotional labor to frontline employee creativity from a cognitive perspective. It also advances knowledge about the effects of emotional labor on stress by classifying different kinds of job stress caused by different cognitive appraisals of surfacing acting and deep acting, and revealing the role of hindrance stress as psychological mechanism through which surface acting affects creativity.

Abstract
Purpose
The purpose of this paper is to provide an accurate dynamic model for the flexible cable capture mechanism and to analyze the dynamic characteristics in the capturing process.
Design/methodology/approach
The absolute nodal coordinate formulation (ANCF) that based on the continuum mechanics approach is applied in the capture task using flexible cables. An ANCF cable element in which axial and bending strain energy are taken into account is presented to model the flexible cables. The generalized coordinates of ANCF are absolute displacements and slopes and make no small deformation assumptions; therefore, this element has a remarkable superiority in the large rotation and deformation analysis of flexible cables compared to the conventional floating frame of reference formulation (FFRF). The mass matrix of the cable element is constant, which will reduce the degree of non-linearity of the dynamic equations. The contact force between the steel cables and capture rod is calculated by the non-linear contact dynamic model, in which material and geometry properties of contact bodies are considered.
Findings
The stress distribution of steel cables is investigated in the numerical studies which show that the closer to the ends of the cable, the larger axial forces and smaller bending moments they will be. The reduction of grasping velocity will lead to a decrease in the contact force and the oversize peak value of contact force is more likely to be avoided when reducing the elastic modulus of steel cables to obtain a greater soft capture capability.
Practical implications
The work shows a practical possibility to improve modeling accuracy of the capture mechanism. Results of the analyses can provide references for the design and analysis of the capture task.
Originality/value
The ANCF is first used in the analysis of the capture task with flexible cables, and some useful results which have not been published before are obtained.

Abstract
Purpose
This study sought to determine the role of green human resource management (GHRM) in fostering employees' environmental performance (ENVP). This study aims to advance knowledge related to the role of firms’ GHRM activities in cultivating eco-responsible behaviors among employees, considering green innovation (GI) as a mediator.
Design/methodology/approach
For this study, data of 579 respondents were collected from employees working in the manufacturing industry in India. In all, 579 employees from the manufacturing sector in India participated in the study. The proposed model was tested using SMART PLS 3.3.
Findings
The findings of this study stated that GHRM was found significantly to predict ENVP in the Indian manufacturing industry, and GI exhibited partial mediation. This study emphasizes that GHRM activities carried out by firms encourage employees to engage in innovation to develop green products and find novel green operation processes to improve firms’ ENVP.
Research limitations/implications
As this study is limited to manufacturing organizations in India, the results of this study cannot be generalized; future studies may examine the proposed model in different contexts to generalize findings.
Originality/value
This study encourages policymakers to devise laws to enable organizations to implement GHRM practices. This study contributes to the existing literature on the environmental aspects of corporate social responsibility and environmental management. This study is one of the few attempts that seek to assess the relationship between GHRM, ENVP and GI in the Indian manufacturing industry. The contribution of this paper is significant to limit GHRM literature, as it empirically investigates the association between GHRM and ENVP.

Abstract
Purpose
Traditional algorithms require at least two complete vector observations to estimate orientation parameters. However, sensor faults and disturbances may cause some components of vector observations unavailable. This paper aims to propose algorithms to realize orientation estimation using vector observations with one or two components lost.
Design/methodology/approach
The fundamental of the proposed method is using norm equation and dot product equation to estimate the lost components, then, using an improved TRIAD to calculate attitude matrix. Specific algorithms for one and two lost components cases are constructed respectively, and the nonuniqueness of orientation estimation is analyzed from a geometric point of view. At last, experiments are performed to test the proposed algorithms.
Findings
The loss of components results in the loss of orientation information. The introduction of the norm equation and dot product equation can partially compensate for the loss of information. Experiment results and analysis show that the proposed algorithms can provide effective orientation estimation, and in vast majority of applications, the proposed algorithms can provide a unique solution in one lost component case and double solutions in two lost components case.
Originality/value
The proposed method addresses the problem of orientation estimation when one or two components of vector observations are unavailable. The introduction of the norm equation and dot product equation makes the calculation cost low, while the analyses from a geometric point of view makes the study of nonuniqueness more intuitive.

This paper aims to present a simplified solution method for the elasto-plastic consolidation problem under different stress paths.
Abstract
Purpose
This paper aims to present a simplified solution method for the elasto-plastic consolidation problem under different stress paths.
Design/methodology/approach
First, a double-yield-surface model is introduced as the constitutive model framework, and a partial derivative coefficient sequence is obtained by using numerical approximation using Gauss nuclear function to construct a discretization constitutive model which can reflect the influence of different stress paths. Then, the model is introduced to Biot’s consolidation theory. Volumetric strain of each step as the right-hand term, the continuity equation is simplified as a Poisson equation and the fundamental solution is derived by the variable separation method. Based on it, a semi-analytical and semi-numerical method is presented and implemented in a finite element program.
Findings
The method is a simplified solution that is more convenient than traditional coupling stiffness matrix method. Moreover, the consolidation of the semi-infinite foundation model is analyzed. It is shown that the numerical method is sufficiently stable and can reflect the influence of stress path, loading distribution width and some other factors on the deformation of soil skeleton and pore water pressure.
Originality/value
Original features of this research include semi-numerical semi-analytical consolidation method; pore water pressure and settlements of different stress paths are different; maximum surface uplift at 3.5a; and stress path is the main influence factor for settlement when loading width a > 10 m.
