Abstract

Purpose

The purpose of the present study is to examine the relationship between spiritual leadership and employees' alienative commitment to the organization, both directly and indirectly, via employee social capital. We also test the role of employee political skill as a boundary condition of the indirect spiritual leadership–alienative commitment link.

Design/methodology/approach

Time-lagged data were collected from 491 employees in various manufacturing and service organizations. Data were analyzed using structural modeling equation in Mplus (8.6).

Findings

Spiritual leadership was negatively associated with alienative commitment, both directly and indirectly, via social capital. Employee political skill moderated the indirect relationship between spiritual leadership and alienative commitment, such that the relationship was stronger when employee political skill was high (vs low).

Practical implications

The demonstration of spiritual leadership's behaviors by both managers and employees can develop employees' social capital at work, which in turn can reduce employees' negative commitment to the organization. Likewise, improving employees' political skills can help leadership diminish alienative commitment.

Originality/value

The present work contributes to the literature on spiritual leadership by foregrounding how and why spiritual leadership undermines employee alienative commitment to the organization. By doing so, the study also enhances the nomological networks of the antecedents and outcomes of social capital and contributes to the scant literature on negative alienative commitment. Given the prevalence and negative repercussions of alienative commitment for employees' and organizations' productivity and performance, our findings are timely and relevant.

Abstract

Purpose

This study aims to investigate direct and indirect (via perceived caring climate) links between spiritual leadership and hazing at work in the hospitality context. The authors also test the role of employee interpersonal justice values as a boundary condition.

Design/methodology/approach

The authors collected time-lagged data from 441 newcomers and their 441 peers (existing hotel employees) and analyzed the data using structural modeling equation in Mplus (8.6).

Findings

The authors found a negative relationship between spiritual leadership and hazing behaviors. Further, perceived caring climate mediated the relationship between spiritual leadership and hazing behaviors. The results also provided support for employee interpersonal justice values as the boundary condition on both the direct relationship between spiritual leadership and perceived caring climate and the indirect relationship between spiritual leadership and workplace hazing.

Practical implications

The authors suggest that there is a value in having organizational leaders who demonstrate spiritual leadership behaviors. This will enhance hospitality employees’ perceptions of a caring climate and undermine their engagement in hazing behaviors.

Originality/value

This study makes an important contribution to the nascent literature on workplace hazing behaviors and spiritual leadership in the hospitality context. The study is also noteworthy because it provides important insights into the antecedents and outcomes of perceived caring climate, an important contextual resource that has imperative implications for hospitality employees’ hazing behaviors.

Abstract

Purpose

This paper aims to improve the computational efficiency of higher-order accurate Noye–Hayman [NH (9,9)] implicit finite difference scheme for the solution of electromagnetic scattering problems in tunnel environments.

Design/methodology/approach

The proposed method consists of two major steps: First, the higher-order NH (9,9) scheme is numerically discretized using the finite-difference method. The second step is to use an algorithm based on hierarchical interpolative factorization (HIF) to accelerate the solution of this scheme.

Findings

It is observed that the simulation results obtained from the numerical tests illustrate very high accuracy of the NH (9,9) method in typical tunnel environments. HIF algorithm makes the NH (9,9) method computationally efficient for two-dimensional (2D) or three-dimensional (3D) problems. The proposed method could help in reducing the computational cost of the NH (9,9) method very close to O(n) usual O(n3) for a full matrix.

Research limitations/implications

For simplicity, in this study, perfect electric conductor boundary conditions are considered. Future research may also include the utilization of meteorological techniques, including the effects of backward traveling waves, and make comparisons with the experimental data.

Originality/value

This study is directly applicable to typical problems in the field of tunnel propagation modeling for both national commercial and military applications.

Abstract

Purpose

Continuous fiber thermoplastics are recyclable and have excellent specific strength and stiffness, making them desirable materials for use in structural components. Recent advancements in continuous fiber additive manufacturing processes allow designers to make notches or perforations during printing, eliminating the need for labor-intensive and long drilling processes, which cause delaminations and premature failure. The purpose of this study is to evaluate the potential of continuous fiber 3D printing in creating notches for structural composites.

Design/methodology/approach

This study evaluates the notching process in nylon-based continuous-glass fiber thermoplastic composites through mechanical drilling and three-dimensional (3D) printing. Three different sample configurations were tested for tensile and fracture characteristics: Un-notched; with notches drilled mechanically; and with notches printed using a 3D printer, with the fibers routed around the notch. Further, finite element models were used to understand the stress concentration around the notches.

Findings

The tensile strength of notched samples was lower than that of unnotched samples in both 3D-printed and mechanically drilled cases. The presence of substantial delamination in mechanically drilled samples led to a 15% decrease in strength compared to 3D-printed samples. The increase in notch size resulted in a decrease in strength, as anticipated.

Practical implications

The techniques developed in this study may be easily applied to comparable situations involving several types of continuous fiber thermoplastic composites.

Originality/value

Both experimental and computational modeling results indicate that delamination because of the drilling process is the prime factor responsible for the significant decrease in residual strength. Furthermore, it also showed that the steering of the fiber around the notch had a minimal impact, and augmenting the stiffness in proximity to the notch can alleviate stress concentration.

Abstract

Purpose

The purpose of this paper is to provide a brief introduction of the finite difference based parabolic equation (PE) modeling to the advanced engineering students and academic researchers.

Design/methodology/approach

A three-dimensional parabolic equation (3DPE) model is developed from the ground up for modeling wave propagation in the tunnel via a rectangular waveguide structure. A discussion of vector wave equations from Maxwell’s equations followed by the paraxial approximations and finite difference implementation is presented for the beginners. The obtained simulation results are compared with the analytical solution.

Findings

It is shown that the alternating direction implicit finite difference method (FDM) is more efficient in terms of accuracy, computational time and memory than the explicit FDM. The reader interested in maximum details of individual contributions such as the latest achievements in PE modeling until 2021, basic PE derivation, PE formulation’s approximations, finite difference discretization and implementation of 3DPE, can learn from this paper.

Research limitations/implications

For the purpose of this paper, a simple 3DPE formulation is presented. For simplicity, a rectangular waveguide structure is discretized with the finite difference approach as a design problem. Future work could use the PE based FDM to study the possibility of utilization of meteorological techniques, including the effects of backward traveling waves as well as making comparisons with the experimental data.

Originality/value

The proposed work is directly applicable to typical problems in the field of tunnel propagation modeling for both national commercial and military applications.

Abstract

Purpose

This study aims to investigate the potential positive correlation between inclusive leadership and hotel frontline employees’ (FLEs) customer stewardship (CS) behavior, using the conservation of resource theory as its foundation. It hypothesizes that role breadth self-efficacy (RBSE) acts as a mediating factor in this relationship, with employee conscientiousness serving as a significant moderating variable.

Design/methodology/approach

A time-lagged survey design was used, spanning over three rounds to collect data from 348 hotel FLEs and 42 managers. The analysis was conducted using structural equation modeling in Mplus version 8.6.

Findings

The study revealed a positive association between inclusive leadership and FLE CS, both directly and indirectly through RBSE. The results also showed that FLE conscientiousness moderated the direct link between inclusive leadership and RBSE, as well as the indirect link between inclusive leadership and FLE CS.

Practical implications

The evidence suggests that inclusive leadership behaviors among hospitality managers may elevate FLE CS behaviors, implying significant benefits for the success of hospitality organizations. Managers should focus on enhancing FLEs’ RBSE to further improve CS behaviors. In addition, by considering FLE conscientiousness, managers can craft targeted strategies to maximize the impact of inclusive leadership on CS behaviors.

Originality/value

This research contributes to the limited body of knowledge on the precursors of CS behavior by explaining both direct and indirect connections with inclusive leadership. Furthermore, it broadens the understanding of the conditions under which leadership most effectively shapes such behaviors.

Abstract

Purpose

Drawing on the conservation of resources theory, this study aims to apply a mixed-method to enrich the literature by investigating interrelationships among training, environmental triggers (environmental knowledge, awareness and concern) and employees' intention to carry out environmental activities.

Design/methodology/approach

This research applied a mixed-method carried out in Vietnam. By using the time-lagged data, Study 1 (quantitative research) was employed to test hypotheses. With Study 2 (qualitative research), four in-depth interviews were conducted to gain insight into a few unexpected findings from Study 1.

Findings

Study 1 indicates that environmental training is critical to directly boost not only the three environmental triggers but also employees' intention to engage in environmental activities. The findings further point out that environmental concern and awareness mediate the relationship between environmental training and employees' intention to engage in environmental activities. Unexpectedly, connections from environmental concern and awareness to employees' intentions were not moderated by environmental knowledge. The findings of Study 2 shed light on the role of environmental knowledge.

Originality/value

Based on the conservation of resources and social exchange theories, the research contributes to the existing literature by providing a better understanding of how environmental training stimulates employees' intention to implement environmental activities. The findings may be helpful for managers to encourage employees to contribute to organizations' green objectives.

Abstract

Purpose

The present study aimed to test the hypothesis that ethical leadership positively contributes to exploitative learning and explorative learning simultaneously and then examine the moderating role of work centrality in the relationships of ethical leadership with exploitative learning and explorative learning.

Design/methodology/approach

Time-lagged survey data were collected from 257 middle managers and their 257 immediate supervisors in 76 firms in China. Data were analyzed using structural equation modeling and Hayes' PROCESS macro for SPSS.

Findings

The results revealed that ethical leadership positively contributed to exploitative learning and explorative learning simultaneously. Importantly, the authors found that work centrality strengthened the positive relationships of ethical leadership with both exploitative learning and explorative learning.

Practical implications

The findings can help organizations enhance exploitative learning and explorative learning simultaneously and enable them to gain a sustainable competitive advantage.

Originality/value

Although explorative learning and exploitative learning together constitute fundamental resources for organizations' long-term success, prior research has not looked into whether and when leader behaviors facilitate explorative learning and exploitative learning simultaneously. The study contributed to fill this gap by introducing ethical leadership, signifying its positive role in enhancing both explorative learning and exploitative learning, and establishing work centrality as a moderator to reinforce these two positive relationships.

Abstract

Purpose

Using the conservation of resources (COR) theory, the present study aims to examine the role of participative leadership in frontline service employees (FLEs)’ service recovery performance. The present study also tests FLEs’ role breadth self-efficacy (RBSE) as a theoretically relevant mediator and FLE trait mindfulness as an important moderator.

Design/methodology/approach

Data were collected using time-lagged (three rounds, two weeks apart) from two sources (193 FLEs and 772 customers, who experienced a service failure). Structural equation modeling (Mplus, 8.6) was employed to analyze the data.

Findings

The results revealed that participative leadership was positively associated with FLEs service recovery performance, both directly and indirectly, via RBSE. The results also showed that FLE trait mindfulness moderated the link of participative leadership with RBSE and the indirect association of participative leadership with service recovery performance, via RBSE.

Practical implications

This study suggests that organizational leaders who exhibit participative leadership behavior are valuable for organizations. By demonstrating such behaviors, they boost FLEs' RBSE, which in turn improves their service recovery performance.

Originality/value

The present work makes important contributions to the literature on service recovery performance by foregrounding two important yet overlooked antecedents (participative leadership and RBSE) of FLE service recovery performance. The present work also contributes to the nascent literature on the antecedents and outcomes of RBSE in service contexts.

Abstract

Purpose

Prior research demonstrated that China's Outward FDI (OFDI) is aimed at sustaining long-term economic growth by promoting industrialization and technological upgrading in the country. However, empirical evidence on the effectiveness of this strategy remains scarce. This study intends to fill this gap by exploiting endogenous changes in industrial productivity stemming from OFDI to examine if China's new strategy to spur OFDI is economically beneficial for the industries involved.

Design/methodology/approach

The authors employed the two-step system-GMM and pooled mean group approaches on a panel dataset of 18 Chinese industries over the 2004–2017 period. The industrial sectors are further classified into the state dominated and non-state dominated ones to evaluate whether the productivity growth impact of OFDI varies by the level of ownership structure. Besides, the dataset is further decomposed into the ex ante and ex-post BRI era to test if this initiative has altered the underlying relationship.

Findings

The results provide robust evidence that China's OFDI through reverse spillover effects promotes productivity growth in the domestic industries, and such productivity gains are greater for the non-state dominated industries, and the OFDI in the BRI era. The findings suggest that OFDI can act as a catch-up strategy to release excess capacity and acquire technology and smart business practices.

Originality/value

This study is the first attempt to highlight the reverse productivity spillovers associated with OFDI at the industrial level. The study's findings guide the government officials and the practitioners of foreign investment to better understand the implications of their investment projects in terms of technology improvements and to optimize market opportunities.
