Abstract

Purpose

Drawing on the conservation of resources (COR) theory, this study aims to examine the influence of abusive supervision on hospitality employees’ helping behaviors, especially, the joint moderating effects of proactive personality and ability to manage resources (i.e. RMA) in the hypothesized relationship.

Design/methodology/approach

Using a two-phase design, this study gathered data from 353 employees of ten hotels located in China. To test the hypotheses, the study conducted a series of hierarchical multiple regression analyses.

Findings

Findings demonstrated that abusive supervision was negatively related to hotel employees’ helping behaviors. Moreover, both proactive personality and RMA jointly moderated the abusive supervision–helping behavior relationship. Specifically, when both proactive personality and RMA had high degrees, the abusive supervision–employees’ helping behaviors linkage was weakest. Conversely, the strongest impact of abusive supervision on employees’ helping behaviors occurred when both proactive personality and RMA were low.

Practical implications

Hotel managers should reduce mistreatment and cultivate employees’ both proactive personality and RMA, to inhibit the decline of helping behavior resulting from abusive supervision.

Originality/value

First, the current study provides a novel theoretical underpinning of the COR theory to explain the abusive supervision–helping behavior association, particularly in the hospitality context. Second, this study contributes to the boundary effects of abusive supervision on helping behavior by investigating the moderating roles of individual differences (i.e. proactive personality and RMA).

Abstract

Purpose

Drawing on conservation of resources (COR) theory, this study aims to explore the influencing mechanism of exploitative leadership on knowledge hiding. Specifically, this study focuses on the mediating role of psychological distress and the moderating role of hostile attribution bias in affecting the mediation.

Design/methodology/approach

Data were collected from 324 employees of a high-technology company in China by a three-wave questionnaire survey. Hierarchical regression analysis and bootstrapping approach were employed to test hypotheses.

Findings

This study found that exploitative leadership was positively related to knowledge hiding and that psychological distress mediated this relationship. Moreover, the results revealed that the positive relationship between exploitative leadership and psychological distress and the indirect effect of exploitative leadership on knowledge hiding via psychological distress were stronger when hostile attribution was high rather than low.

Practical implications

The findings of this study offer guidance for managers to better undermine the negative effects of exploitative leadership.

Originality/value

First, this study extends the literature on exploitative leadership by verifying the positive effect of exploitative leadership on knowledge hiding. Second, this study enriches one’s understanding of the “black box” underlying the link between exploitative leadership and its consequences by demonstrating the mediating role of psychological distress. Third, by verifying the moderating role of hostile attribution bias, this study provides insights into the boundary conditions of the impact of exploitative leadership.

Abstract

Purpose

Based on social exchange theory and research on proactive personality, this study aims to explore the relationship between abusive supervision and unethical pro-organizational behavior (UPB), taking proactive personality as a boundary condition.

Design/methodology/approach

This study conducted a two-wave questionnaire survey and used data from 353 Chinese employees of a diversified company to test the research hypotheses.

Findings

The relationship between abusive supervision and UPB varied with proactive personality. Specifically, abusive supervision had an inverted U-shaped effect on UPB when proactive personality was high, while abusive supervision was negatively related to UPB when proactive personality was low.

Research limitations/implications

More research are encouraged to replicate our study in different cultural contexts. Besides, future research can gather data from dyads (e.g. supervisor–subordinate dyad and coworker–subordinate dyad) so as to increase the objectivity and validity of the data.

Practical implications

Managers should reduce abusive supervision and elevate proactive employees' moral awareness.

Social implications

This study hopes that the authors’ findings will help practitioners to devote greater attention to managing proactive personality, abusive supervision and UPB in the organization.

Originality/value

First, this study enriches the abusive supervision literature by identifying UPB as a consequence of abusive supervision. Second, this study provides a better understanding of the coping tactics used to combat abusive supervision. Third, this study uncovers a dark side of proactive personality by verifying the moderating effect of proactive personality.

Abstract

Purpose

This study aims to examine the moderating effects of psychological entitlement and perceived organizational support (POS) on the relationship between work connectivity behavior after-hours (WCBA) and job satisfaction.

Design/methodology/approach

Data were collected from 217 full-time employees of an Internet company in China at two points in time separated by about one month. Hierarchical regression and simple slope analyses were conducted to test hypotheses.

Findings

The results showed that WCBA was negatively related to job satisfaction and that this relationship could be mitigated by POS. Moreover, psychological entitlement aggravated this relationship, and this aggravating effect was stronger when POS was at low levels.

Practical implications

Managers should avoid intervening employees' nonwork domains too much. If this is unavoidable, managers should provide adequate organizational support to help employees cope with the challenges brought by WCBA. Besides, managers need to pay close attention to highly entitled employees and take measures to modify their expectations.

Originality/value

First, this study enriches the understanding of what WCBA is and how WCBA works by investigating the influencing mechanism of WCBA from the perspectives of effort–reward imbalance and job demands–resources. Second, by verifying the moderating effects of psychological entitlement and POS, this study provides insights into the boundaries of the WCBA–job satisfaction relationship. Third, this study contributes to the literature on psychological entitlement by identifying its one applicable condition.

Purpose

The purpose of this paper is to study the flow patterns and particle-particle collisions during the sedimentation of multiple circular particles under gravity at intermediate Reynolds numbers through direct numerical simulations (DNS).

Design/methodology/approach

The previously developed lattice Boltzmann-direct forcing/fictitious domain (LB-DF/FD) method is adopted in this work to conduct DNS.

Findings

It is found that the number of particle-particle collisions display a linear growth at long times after an initial evolution, resulting in a constant collision rate, which also depends the initial arrangement.

Originality/value

The problem of particle-particle collisions during sedimentation with two kinds of particle density has not been considered before and it is of special importance in various industries.

Abstract

Purpose

The purpose of this paper is to test the relationship between external auditor selection and charity donation, that is, whether the governance role of external audit is effective and how it plays in China's charitable market.

Design/methodology/approach

Using data from 2005 to 2009 of China's national charity, the paper applies empirical regression method to test the hypothesis.

Findings

Empirical evidence suggests that, when charities select national Big 100 as the auditors, the governance role of audit plays effectively, thus attracts more donators. When charities select successful bidders of Civil Affairs Bureau as the auditors, the governance role of audit cannot play effectively, thus will not increase donation significantly.

Research limitations/implications

Charities' annual report disclosure is not ample, so research samples could not include the regional charities, and in self‐selection model, independent variables do not include audit fee which could affect the results of self‐selection.

Practical implications

To some extent, the above conclusion suggests governance effect of external audit exist in the charitable market, and the effects depend on high quality audit. In view of the governance effect of high quality audit, the paper's conclusion could provide reference for the current non‐profits governance mechanism construction, at the same time, Civil Affairs Bureau should further improve the tender evaluation content and make them more objective and quantification when they bid the financial auditor, also, they should not be restricted charity choose auditor such as high quality outside the bidding scope.

Originality/value

First, previous literature of external audit research mainly gathered in capital market, but charity market different from the capital market, it is significance for whole non‐profit organization. Second, the paper's conclusion could provide some empirical evidence available for the perfection of charity governance mechanisms.

Abstract

Purpose

Fault diagnosis methods based on blind source separation (BSS) for rolling element bearings are necessary tools to prevent any unexpected accidents. In the field application, the actual signal acquisition is usually hindered by certain restrictions, such as the limited number of signal channels. The purpose of this study is to fulfill the weakness of the existed BSS method.

Design/methodology/approach

To deal with this problem, this paper proposes a blind source extraction (BSE) method for bearing fault diagnosis based on empirical mode decomposition (EMD) and temporal correlation. First, a single-channel undetermined BSS problem is transformed into a determined BSS problem using the EMD algorithm. Then, the desired fault signal is extracted from selected intrinsic mode functions with a multi-shift correlation method.

Findings

Experimental results prove the extracted fault signal can be easily identified through the envelope spectrum. The application of the proposed method is validated using simulated signals and rolling element bearing signals of the train axle.

Originality/value

This paper proposes an underdetermined BSE method based on the EMD and the temporal correlation method for rolling element bearings. A simulated signal and two bearing fault signal from the train rolling element bearings show that the proposed method can well extract the bearing fault signal. Note that the proposed method can extract the periodic fault signal for bearing fault diagnosis. Thus, it should be helpful in the diagnosis of other rotating machinery, such as gears or blades.

Abstract

Purpose

In this study the aim was to investigate under-deposit corrosion (UDC) behavior and the action effects of amino trimethylene phosphonic acid (ATMP) in the oxygen-contained solution.

Design/methodology/approach

Electrochemical methods and wire beam electrode techniques were used for the study of ATMP action effect for X65 steel under silica sand and CaCO3 particle deposit. Electronic coupon technique was used for the study of galvanic effect caused by the deposits and the action effect of ATMP.

Findings

ATMP would cause localized corrosion for the silica sand-covered steel. However, it could inhibit the localized corrosion of the steel beneath CaCO3 particle deposit. Galvanic effect test showed that the galvanic effect caused by the deposits was an important factor for the acceleration of UDC. ATMP had an obvious promotion effect for the galvanic current between bare coupon and silica sand covered coupon and different degrees of localized corrosion were observed beneath both deposits.

Originality/value

The authors believe that the paper may be of particular interest to the readers of the journal as the measurement methods for the UDC of X65 pipeline steel. The experiment they did in the laboratory found that the inhibitor ATMP has a good inhibition effect for bare steel, but it would accelerate the UDC. Different kinds of deposits would have different influences for the UDC behavior with inhibitor added.

Abstract

Purpose

The purpose of this paper is to investigate the gas flow characteristics in near wall region and the velocity slip phenomenon on the wall in nano-channels based on the molecular dynamics simulation.

Design/methodology/approach

An external gravity force was employed to drive the flow. The density and velocity profiles across the channel, and the velocity slip on the wall were studied, considering different gas temperatures and gas-solid interaction strengths.

Findings

The simulation results demonstrate that a single layer of gas molecules is adsorbed on wall surface. The density of adsorption layer increases with the decrease of gas temperature and with increase of interaction strength. The near wall region extents several molecular diameters away from the wall. The density profile is flatter at higher temperature and the velocity profile has the traditional parabolic shape. The velocity slip on the wall increases with the increase of temperature and with decrease of interaction strength linearly. The average velocity decreases with the increase of gas-solid interaction strength.

Originality/value

This research presents gas flow characteristics in near wall region and the velocity slip phenomenon on the wall in nano-channels. Some interesting results in nano-scale channels are obtained.
