Abstract

Purpose

Based on self-determination theory, this research paper aims to explore the implication of exploitative leadership for hospitality employees’ proactive customer service performance (PCSP) via harmonious passion for work (HPFW) and the moderating mechanism of power distance.

Design/methodology/approach

The authors’ sample included a total of 207 leader–follower dyads from three Chinese hotels. Hierarchical multiple regression and the PROCESS macro were used to analyze the data.

Findings

The results indicated that exploitative leadership has a negative indirect relationship with hospitality employees’ PCSP through decreased HPFW, and power distance plays a protective role of alleviating the negative implications of exploitative leadership for hospitality employees’ HPFW and PCSP.

Practical implications

Hotels are suggested to develop strict codes of conduct and adopt zero-tolerance policies for exploitative leadership. Additionally, hotels should also act to improve employees’ HPFW and pay attention to low-power-distance employees.

Originality/value

This research enriches exploitative leadership literature by investigating its effect on PCSP. Further, this research investigates HPFW as a mechanism linking exploitative leadership to PCSP. Finally, this research establishes the relationships among exploitative leadership, HPFW and PCSP by investigating the contingent impact of power distance.

Abstract

Purpose

Knowledge-based organizations is a new paradigm for business. Knowledge management (KM) is important for supporting core business processes. This paper aims to define an open innovation (OI)-driven KM implementation for effectively executing the support.

Design/methodology/approach

KM is important for supporting organizational innovation. OI plays a critical determinant role in defining the design of KM for effectively supporting OI. Further, the final goal of KM is to reach the success of OI-based KM implementation. A model is thus proposed for connecting OI as a driver to a design of KM and, in turn, KM implementation. Survey is conducted to collect data. Partial least squares is used for analysis.

Findings

The three processes of OI partially present significant impact on the design of KM process and, in turn, a noticeable achievement of KM implementation. The two KM processes indicate an interaction effect for reinforcement mutually. The findings provide rich evidence into the argument that OI-based KM implementation through the mediator of the design of KM process is important for a successful KM in organizations.

Practical/implications

While OI is a phenomenon that has increasingly become critical for the contemporary business, the design of KM mechanism needs to be adapted from the choice of OI process for guaranteeing the success of KM implementation.

Originality/value

Extant theories did not provide such an approach to develop an effective KM implementation in terms of the important management concept, OI, in organizations. This model empirically demonstrates its capability to work on this issue.

Abstract

Purpose

By investigating trust in the organization as a mediator and traditionality as a moderator, this study aims to examine the effect perceived organizational exploitation poses on frontline hotel employees’ service performance.

Design/methodology/approach

A three-wave survey that targets 219 supervisor–subordinate dyads from four Chinese hotels was conducted to test the hypotheses. The authors used SPSS 20.0 and AMOS 21.0 to analyze the data and verify the theoretical model.

Findings

This study found that perceived organizational exploitation exerts a destructive impact on frontline hotel employees’ service performance. Trust in the organization is a full mediator of the link connecting perceived organizational exploitation to service performance. Furthermore, traditionality weakens perceived organizational exploitation’s impact on trust in the organization and subsequent service performance.

Practical implications

The authors’ findings remind hotels to cease exploiting their employees to avoid compromising service performance. Hotels should also endeavor to instill trust among employees toward the hotel and allocate more attention to employees with lower levels of traditionality.

Originality/value

First, to the best of the authors’ knowledge, this study is among the first to explore the impact of perceived organizational exploitation on frontline hotel employees’ service performance. Second, this study reveals a novel mechanism underlying the connection between perceived organizational exploitation and service performance. Finally, this study identifies frontline hotel employees’ traditionality as a vital moderator that mitigates the negative relationships among perceived organizational exploitation, trust in the organization and service performance.

Abstract

Purpose

Drawing from self-determination theory, this study aims to examine the effect of leader humor on frontline hospitality employees’ service performance and proactive customer service performance (PCSP) via harmonious passion (HP) for work with employee neuroticism as the moderating mechanism.

Design/methodology/approach

This study controlled for the nested effect and tested all the hypotheses with Mplus 7.0 using a time-lagged three-wave survey of 232 Chinese supervisor–subordinate dyads.

Findings

The results indicated that leader humor promotes frontline hospitality employees’ service performance and PCSP by enhancing their HP. Furthermore, neuroticism was shown to strengthen the direct impact of leader humor on employee HP and its indirect impact on employee service performance and employee PCSP through HP.

Originality/value

First, this research contributes to the leader humor literature through exploring its impact on the service performance and PCSP of frontline hospitality employees. Second, this research develops a new framework to explain the leader humor-employee service outcomes relationship using self-determination theory. Finally, the focus on the moderating role of neuroticism helps to explain the “when” question of leader humor.

Abstract

Purpose

The change rules of the shielding effectiveness (SE) of the sleeve has not been clarified, which leads to the lack of the basis for the design, manufacture and evaluation of the electromagnetic shielding (EMS) clothing.

Design/methodology/approach

According to a simplified analysis model, a series of sleeve samples with different fabrics and styles are designed and manufactured. The SE of the sleeve is tested with the proposed special test method in a semi-anechoic chamber to analyze the influence of different factors on the SE of the sleeve.

Findings

The SE is greatly reduced about 60–90% after the fabric is manufactured into the sleeve. The larger the sleeve length is, the higher the peak value of the SE is. When the sleeve length is low, the SE value is easy to appear negative. As the cuff circumference increases, the SE of the sleeve will change with the frequency band. The influence of the cuff style on the SE of the sleeve mainly depends on the cuff width and style. The larger the cuff width is, the lower the overall SE of the sleeve is. The more wrinkles there are at the cuff, the better the SE of the sleeve is.

Originality/value

Our results provide a reference for the design, production and evaluation of the sleeve and the whole EMS clothing.

Abstract

Purpose

One of the crucial steps in the molded bra production is the process of developing the mold head. The purpose of this paper is to determine the final cups style and size. Compared with traditional development process of the mold head, less time-consuming and a more quantitative method is needed for the design and modification of the mold head.

Design/methodology/approach

A three-dimensional (3D) numerical model for the simulation of large compressive deformation was built in this paper to research the foam bra cup molding process. Since the head cones have more representative than the mold heads, the male and female head cones were used in the simulation. All of the solid shapes are modeled by using 3D Solid 164 elements as well as an automatic surface-to-surface contact between head cones.

Findings

Simulation of the foam cup molding process is conducted by inputting different properties of the foam material and stress-strain curves under different molding temperatures.

Research limitations/implications

In order to simulate the laminated foam moulding process, heat transfer through a layered textile assembly can be studied by using the thermo-mechanical coupled FE model.

Practical implications

According to the different foam performance parameters under different temperatures along with different head cone shapes, distribution and variation in the stress field can be obtained as well as the ultimate capacity of foam materials.

Social implications

A computer-aided parametric design system for the mold heads provides an effective solution to improving the development process of mold heads.

Originality/value

The distribution and variation in the stress fields can be analyzed through simulation, providing a reference for the mold head design.

Abstract

Purpose

The purpose of this paper is to analyze numerically the blowup in finite time of the solutions to a one-dimensional, bidirectional, nonlinear wave model equation for the propagation of small-amplitude waves in shallow water, as a function of the relaxation time, linear and nonlinear drift, power of the nonlinear advection flux, viscosity coefficient, viscous attenuation, and amplitude, smoothness and width of three types of initial conditions.

Design/methodology/approach

An implicit, first-order accurate in time, finite difference method valid for semipositive relaxation times has been used to solve the equation in a truncated domain for three different initial conditions, a first-order time derivative initially equal to zero and several constant wave speeds.

Findings

The numerical experiments show a very rapid transient from the initial conditions to the formation of a leading propagating wave, whose duration depends strongly on the shape, amplitude and width of the initial data as well as on the coefficients of the bidirectional equation. The blowup times for the triangular conditions have been found to be larger than those for the Gaussian ones, and the latter are larger than those for rectangular conditions, thus indicating that the blowup time decreases as the smoothness of the initial conditions decreases. The blowup time has also been found to decrease as the relaxation time, degree of nonlinearity, linear drift coefficient and amplitude of the initial conditions are increased, and as the width of the initial condition is decreased, but it increases as the viscosity coefficient is increased. No blowup has been observed for relaxation times smaller than one-hundredth, viscosity coefficients larger than ten-thousandths, quadratic and cubic nonlinearities, and initial Gaussian, triangular and rectangular conditions of unity amplitude.

Originality/value

The blowup of a one-dimensional, bidirectional equation that is a model for the propagation of waves in shallow water, longitudinal displacement in homogeneous viscoelastic bars, nerve conduction, nonlinear acoustics and heat transfer in very small devices and/or at very high transfer rates has been determined numerically as a function of the linear and nonlinear drift coefficients, power of the nonlinear drift, viscosity coefficient, viscous attenuation, and amplitude, smoothness and width of the initial conditions for nonzero relaxation times.

Abstract

Purpose

Industrial simulations of turbulent flows often rely on Reynolds-averaged Navier-Stokes (RANS) turbulence models, which contain numerous closure coefficients that need to be calibrated. This paper aims to address this issue by proposing a semi-automated calibration of these coefficients using a new framework (referred to as turbo-RANS) based on Bayesian optimization.

Design/methodology/approach

The authors introduce the generalized error and default coefficient preference (GEDCP) objective function, which can be used with integral, sparse or dense reference data for the purpose of calibrating RANS turbulence closure model coefficients. Then, the authors describe a Bayesian optimization-based algorithm for conducting the calibration of these model coefficients. An in-depth hyperparameter tuning study is conducted to recommend efficient settings for the turbo-RANS optimization procedure.

Findings

The authors demonstrate that the performance of the k-ω shear stress transport (SST) and generalized k-ω (GEKO) turbulence models can be efficiently improved via turbo-RANS, for three example cases: predicting the lift coefficient of an airfoil; predicting the velocity and turbulent kinetic energy fields for a separated flow; and, predicting the wall pressure coefficient distribution for flow through a converging-diverging channel.

Originality/value

To the best of the authors’ knowledge, this work is the first to propose and provide an open-source black-box calibration procedure for turbulence model coefficients based on Bayesian optimization. The authors propose a data-flexible objective function for the calibration target. The open-source implementation of the turbo-RANS framework includes OpenFOAM, Ansys Fluent, STAR-CCM+ and solver-agnostic templates for user application.

Abstract

Purpose

The purpose of this paper is to examine the pricing efficiency of the Malaysian crude palm oil (CPO) market before and after the structural break. This study uses the daily closing price of CPO and CPO futures (CPO-F) for the period ranging from June 2009 to August 2016 while taking structural breaks into account.

Design/methodology/approach

In this study, symmetric and asymmetric long-run relationship model are employed, such as the Johansen cointegration, VECM, TAR and M-TAR models, to examine the impact of structural breaks on the pricing efficiency of the Malaysian CPO market.

Findings

This finding establish that Malaysian CPO price is efficient before and after the structural break. The consistent efficiency of the Malaysian CPO market supports the trading of the CPO-F in Globex and the use of Malaysian CPO pricing as the reference price. This study establishes that a structural break in the Malaysian CPO price series does not affect the pricing efficiency of the market.

Research limitations/implications

This study shows that using Malaysian CPO price as a reference price is sustainable even in the event of a structural break. Therefore, market participants in the Malaysian CPO market have less to worry about the CPO price as it supports the weak form of efficiency. Price deviation in the short run may not lead to arbitrage profit as transaction cost may not be covered.

Practical implications

This study implies that if there is distortion in the price due to shocks, both manufacturers and producers need to hedge their positions in the futures market (subject to their positions in the underlying market). By entering into the futures market, pricing is locked in advance; hence, price risk is eliminated. Such a distortion could also affect the efficiency of the CPO price, therefore this study also addresses the issue of efficiency of the local CPO market.

Originality/value

Previous studies on Malaysian CPO pricing efficiency did not take the effect of structural break into consideration, making it difficult for these studies to show consistency in the efficiency of the Malaysian CPO market.

Abstract

Purpose

The purpose of this paper is to investigate women managers’ work values in the Chinese sociocultural context and to explain how these work values affect their career success. This paper also explores how social and cultural factors affect Chinese women’s work value formation process.

Design/methodology/approach

Using a grounded theory approach, the authors collected and analyzed data through in-depth interviews with 12 women managers in the banking industry in northeast China.

Findings

The analysis identified eight dimensions of Chinese women’s work values and how they affect women’s career success in the Chinese context. The authors also found that although both social and cultural factors affect women’s work values, the effect of traditional Chinese culture is still profound.

Originality/value

The study extends the literature on Chinese women’s work values and provides a better understanding of traditional Chinese culture’s effect on contemporary Chinese women, particularly in developing cities.
