Abstract

Purpose

This study aims to develop a new method to treat the numerical singularity at the critical nodes of two skew coordinates, and optimize the leakage of micro herringbone grooved journal bearings (MHGJBs) with this method.

Design/methodology/approach

A side leakage numerical algorithm is proposed by using the skew meshes with a virtual node (SMVN) method to evaluate the effects of groove angle, bank/groove ratio, groove depth and groove number on load capacity, friction and side leakage of MHGJB.

Findings

The SMVN method is effective in treating the numerical singularity at the critical nodes of two skew coordinates. Besides, a group of optimized parameters of micro herringbone groove is obtained which can not only minimize the side leakage but also improve the load capacity and friction force.

Originality/value

A virtual node method was proposed, which can significantly improve the calculation accuracy in the side leakage model.

Abstract

Purpose

The tribological behavior, i.e. friction coefficient and wear rate, and vibration characteristics of the water-lubricated bearing was investigated. The water-lubricated bearing is made of three different materials, i.e. polyether-ether-ketone (PEEK), polyimide (PI) and nitrile-butadiene rubber (NBR).

Design/methodology/approach

The tribological behavior was investigated experimentally on a specially designed test rig. Three vibration sensors were used to record the vibration of the bearing.

Findings

The results indicated that the variation of friction coefficient with rotation speed agrees well with the trend of Stribeck curve. The tested friction coefficient of rubber bearing is higher than that of the other two bearings whether it is in the state of mixed-lubrication or hydrodynamic lubrication, and which causing a larger wear rate in rubber bearing. The PEEK bearing exhibits the best tribological properties due to it has smaller friction coefficient and wear rate. However, it can be found that the rubber bearing gives the minimum vibration acceleration, which means that the rubber bearing has the most potential to improve the stability of water-lubricated bearing rotor system.

Originality/value

In this study, a group of experiment studies conducted on a specially designed test rig. The comprehensive performance, including friction coefficient, vibration acceleration and wear rate, of water-lubricated bearing with three different materials, i.e. PEEK, PI and NBR, was compared systematically. The experiment research may offer a reference for the selection of material in water-lubricated bearing in specific operating conditions.

Abstract

Purpose

This article examines curatorial practices, both traditional and digital, in the Guizhou Provincial Museum’s ethnic exhibition to assess their effectiveness in representing ethnic minority cultures, fostering learning and inspiring curiosity about ethnic textiles and costumes and associated cultures. It also explores audience expectations concerning digital technology use in future exhibitions.

Design/methodology/approach

A mixed-methods approach was employed, where visitor data were collected through questionnaires, together with interviews with expert, museum professionals and ethnic minority textile practitioners. Their expertise proved instrumental in shaping the design of the study and enhancing the overall visitor experience, and thus fostering a deeper appreciation and understanding of ethnic minority cultures.

Findings

Visitors were generally satisfied with the exhibition, valuing their educational experience on ethnic textiles and cultures. There is a notable demand for more immersive digital technologies in museum exhibitions. The study underscores the importance of participatory design with stakeholders, especially ethnic minority groups, for genuine and compelling cultural representation.

Originality/value

This study delves into the potentials of digital technologies in the curation of ethnic minority textiles, particularly for enhancing education and cultural communication. Ethnic textiles and costumes provide rich sensory experience, and they carry deep cultural significance, especially during festive occasions. Our findings bridge this gap; they offer insights for museums aiming to deepen the visitor experiences and understanding of ethnic cultures through the use of digital technologies.

Abstract

Purpose

This paper aims to describe a method for efficient frequency domain model order reduction. The method attempts to combine the desirable attributes of Krylov reduction and proper orthogonal decomposition (POD) and is entitled Krylov enhanced POD (KPOD).

Design/methodology/approach

The KPOD method couples Krylov’s moment-matching property with POD’s data generalization ability to construct reduced models capable of maintaining accuracy over wide frequency ranges. The method is based on generating a sequence of state- and frequency-dependent Krylov subspaces and then applying POD to extract a single basis that generalizes the sequence of Krylov bases.

Findings

The frequency response of a pre-stressed microelectromechanical system resonator is used as an example to demonstrate KPOD’s ability in frequency domain model reduction, with KPOD exhibiting a 44 per cent efficiency improvement over POD.

Originality/value

The results indicate that KPOD greatly outperforms POD in accuracy and efficiency, making the proposed method a potential asset in the design of frequency-selective applications.

Abstract

Purpose

This study aims to investigate the predictive role of team personality composition in facilitating shared leadership through team member exchange (TMX), while also to examine the moderating effect of organizational culture.

Design/methodology/approach

The authors conducted a two-stage online survey and selected the customer service teams, claims teams and financial teams of 26 Chinese insurance companies as the research samples. The authors finally obtained validated questionnaires from 107 teams with 457 members. The hypothesized relationships were tested using SPSS 25.0 and Mplus.

Findings

The results indicate that both team relationship-oriented and task-oriented personality composition have significant positive effects on shared leadership with team-member exchange serving as a full mediator for both paths. As a boundary condition, organizational culture (i.e. including internal integration values and external adaptation values) has a moderating effect on the influence of TMX on shared leadership.

Originality/value

The study investigates the predictive role of team personality composition on shared leadership, which complements the empirical studies of shared leadership antecedents in the literature. Drawing on social exchange perspective, the authors find out that TMX serves as a mediator between team personality composition and shared leadership. The authors also identify the moderating effect of organizational culture on the emergence of shared leadership. The research emphasizes the contextual boundary condition in this process.

Abstract

Purpose

This systematic review synthesizes the recent literature (2010–2020) on hospitality employees’ emotions, affect and moods. This study has three objectives: to clarify the definitions of emotions, affect and moods; to explain how theories are integrated into understanding hospitality employees’ emotions, affect and moods; and to assess how emotions, affect and moods are measured.

Design/methodology/approach

Using seven major databases, the authors selected 61 peer-reviewed academic journal articles published in hospitality outlets for review. We based our study on five stages of conducting a systematic review: scoping, planning, identification, screening and eligibility.

Findings

Affect is an umbrella term encompassing moods and emotions. Emotions are distinct from emotion-laden constructs, such as emotional labor and emotional intelligence. Theories on conservation of resources, emotional labor and social exchange have been most frequently used to understand hospitality employees’ emotions. However, they overlooked the dynamic nature of emotions when using these theories. Hospitality researchers often used a subset of the positive and negative affect scale and did not discuss back-translation.

Practical implications

Hospitality employees’ emotions lead to far-reaching consequences in attitudes, intentions and behaviors in work and non-work domains. Effective practices (e.g. creating a supportive climate) that help evoke positive employee emotions and reduce negative employee emotions are thus desirable.

Originality/value

Our findings crystallize the understanding of emotions, affect and moods of hospitality employees. We further provide a roadmap for future research on hospitality employees’ emotions. Data triangulation, cross-cultural research and mixed emotions are novel opportunities for future research.

Abstract

Purpose

The Chinese construction industry is experiencing a rapid growth these days. Due to the requirements of energy conservation, emission reduction and construction waste management, the development of prefabricated buildings (PBs) has attracted much attention in the Chinese construction industry. However, the development of PBs are still in their infancy in China, which have been negatively impacted by many obstacles. It is of great significance to clarify and analyze these obstacles for the purpose of promoting the development of PBs in China. Due to the wideness and complex features of obstacles, the existing literature exploring the research topic lacks comprehensiveness. The purpose of this paper is to systematically identify and discuss the obstacles that hinder the development of PBs in China.

Design/methodology/approach

This paper adopts the method of news report analysis based on the news reports retrieved from China National Knowledge Infrastructure (CNKI) and nine major portals in China. The Term Frequency-Inverse Document Frequency (TF-IDF) method of content analysis was used to rank the obstacles according to their importance.

Findings

A total of 79 obstacles to the development of PBs in China are identified, and the 79 obstacles are divided into 8 dimensions. Among the Top 20 obstacles, the government dimension accounted for the highest number of 5, the market and consumer dimension and development organization dimension were 4, Manufacturing Enterprise of Prefabricated Components (PCs) dimension, construction organization dimension and design organization dimension were 2, logistics enterprise dimension was 1, and industry association dimension was 0. Among them, the biggest obstacle is the high transportation costs.

Research limitations/implications

First, data collection may not be very comprehensive. Second, this paper is only based on the obstacles in the development of PBs in China, and the universality of the management conclusions needs to be further strengthened.

Practical implications

The research results help the stakeholders in the Chinese PBs industry to better understand the barriers hindering the industry development in a systemic way, which will help propose appropriate strategies to address these barriers.

Originality/value

This paper clarifies the obstacles of China's PBs and makes an analysis, which is of great value to the development of China's PBs.

Abstract

Purpose

The purpose of this study is to examine how knowledge integration influences entrepreneurial firms’ frugal innovation in the service industry. This study builds a moderated mediation framework to investigate the effect of knowledge integration on frugal innovation via entrepreneurial bricolage and under moderations of competitive intensity and government support.

Design/methodology/approach

This study uses a two-wave survey study among 278 entrepreneurial firms from the service industry in China.

Findings

The findings reveal that knowledge integration positively influences entrepreneurial firms’ frugal innovation via entrepreneurial bricolage. Competitive intensity strengthens both the direct effect of knowledge integration on entrepreneurial bricolage and the indirect effects of knowledge integration on frugal innovation via entrepreneurial bricolage. Government support buffers the effect of entrepreneurial bricolage on frugal innovation but does not influence the indirect effect of knowledge integration on frugal innovation.

Practical implications

This study advocates for managers in entrepreneurial firms to cultivate knowledge integration to improve frugal innovation through activating entrepreneurial bricolage strategy and to pay attention to competitive intensity and government support in the transformation process from knowledge integration to frugal innovation.

Originality/value

While the link between knowledge integration and frugal innovation of entrepreneurial firms in the service industry remains unexplored in the fields of knowledge and innovation management, this study contributes to the knowledge and innovation management literature by exploring the mediating role of entrepreneurial bricolage based on a knowledge-based view and the moderation roles of competitive intensity and government support in this relationship.
