Abstract
Purpose
This study explored students’ variations of insightful academic and career motivation variations of learning and working on defense manufacturing engineering (DME) before and after a project-based program (PBL).
Design/methodology/approach
Interview was adopted to collect students’ insights. The first-round interview was completed within the first week of this summer internship, and the second-round interview was conducted during the final week of this summer internship. Thematic and content analysis were used to explore the factors that affect students’ perception, understanding and attitude to DME before and after the summer internship.
Findings
This paper discloses the improved level of learning and working motivation at the beginning of the project, but with a decrease in the motivation level of working in the DME area at the end of the program. These students showed a continued motivation of interests in pursuing more knowledge in the field. This PBL didn’t bring significant improvement on students’ career motivation for working in the field of DME. However, it demonstrated a highly positive effect on enhance students’ academic motivation (AM) for learning knowledge in the field. Moreover, the students’ concerns and perspectives on this PBL were also explored, which is displayed in the study.

Abstract
Purpose
In light of the burgeoning interest in the Metaverse within educational contexts, this study provides a comprehensive review to address the knowledge gap prevalent among K-12 and higher education teachers and educators. The increasing integration of the Metaverse into classroom settings necessitates a systematic exploration of its impact on subject-specific pedagogy, assessment methods, research methodologies and overall learning outcomes.
Design/methodology/approach
The research design involves a systematic review of 34 selected studies published between 2009 and 2023. The inclusion criteria prioritize investigations into Metaverse applications in classroom teaching, with a focus on subject disciplines, pedagogical approaches, measurement metrics and research methodologies. The selected studies undergo a detailed analysis and synthesis to extract meaningful patterns and trends.
Findings
The analysis reveals a predominant concentration on higher education, encompassing both science, technology, engineering, and mathematics (STEM) and non-STEM disciplines. However, few studies adopt comprehensive experimental designs. This suggests a gap in the methodological rigor of current research on Metaverse integration in education. While the Metaverse's impact on higher education is evident, the study underscores the need for more robust experimental designs and comprehensive research methodologies.
Research limitations/implications
The limited exploration of students' experiences with the Metaverse in educational settings highlights a nascent research area that warrants further investigation. Future research should prioritize measuring students' perceptions and performance through indicators such as test grades to enhance our understanding of the Metaverse's efficacy in educational contexts.
Originality/value
The study aims to offer insights into the current state of Metaverse integration in education and identify areas for further research and development.

This paper aims to introduce a two-dimensional smoothed particle hydrodynamics (SPH) framework for simulating the evaporation and combustion process of fuel droplets.
Abstract
Purpose
This paper aims to introduce a two-dimensional smoothed particle hydrodynamics (SPH) framework for simulating the evaporation and combustion process of fuel droplets.
Design/methodology/approach
To solve the gas–liquid two-phase flow problem, a multiphase SPH method capable of handling high density-ratio problems is established. Based on the Fourier heat conduction equation and Fick’s law of diffusion, the SPH discrete equations are derived. To effectively characterize the phase transition problem, inspired by volume of fluid method, the concept of liquid phase mass fraction of the SPH particles is proposed. The one-step global reaction model of n-hexane is used for the vapor combustion.
Findings
The evaporation and combustion process of single droplet conforms to the law. The framework works out well when the evaporation of multiple droplets involves coalescence process. Three different kinds of flames are observed in succession in the combustion process of a single droplet at different inflow velocity, which agree well with the results of the experiment.
Originality/value
To the best of the authors’ knowledge, this is the first computational framework that has the capability to simulate evaporation and combustion with SPH method. Based on the particle nature of SPH method, the framework has natural advantages in interface tracking.

Abstract
Purpose
In the background of the post-financial crisis era and the transition of China’s economic development, the frequent occurrence of workplace deviant behavior in the economic field, such as stealing and bribery, caused a huge impact on the enterprise. In recent years, the deviant behavior of employees has been increased noticeably. The purpose of this study is to explore the influence of paternalistic leadership on employee deviant behavior in workplace. To have a deep understanding of the relationship between paternalistic leadership and employee deviant behavior, the author’s design rule-oriented ethical climate and self-interest-oriented ethical climate as two mediators in this research model.
Design/methodology/approach
Based on social learning theory and stressor-emotion model, this study conducts an investigation of influence mechanism between paternalistic leadership and workplace deviant behavior. Time-lagged data was collected from 226 employees from six cities in China. To test the hypothesis that the authors developed in this paper, the authors use empirical models from the existing literature about paternalistic leadership on employee deviant behavior. They establish multiple linear regressions to test the hypotheses.
Findings
This study reveals the direct effect of authoritarian leadership on employee deviant behavior and the moderated roles of benevolent leadership and moral leadership, also analysis the mediated mechanism of self-interest-oriented ethical climate and rule-oriented ethical climate. The results show that the higher the degree of authority leaders show in the organization, the easier to stimulate workplace deviance of employee, self-interest-oriented ethical climate and rule-oriented ethical climate play mediated role between authoritarian leadership and workplace deviant behavior. The interaction of benevolent leadership and moral leadership with authoritarian leadership can weaken the self-interest-oriented ethical climate but has nothing to do with rule-oriented ethical climate.
Originality/value
This study has three main contributions to the previous literature. First, this study explores the relationship between authoritarian leadership and employee workplace deviance, which could enrich the research on these negative behaviors in the Chinese context. Second, this study unpacks the “black box” in which authoritarian leadership influences employee workplace deviant behavior. Third, this study further examines the impacts of different combinations of the three factors of paternalistic leadership.

Abstract
Purpose
The purpose of this paper is to present special nine‐node quadrilateral elements to discretize the un‐cracked boundary and the inclined surface crack in a transversely isotropic cuboid under a uniform vertical traction along its top and bottom surfaces by a three‐dimensional (3D) boundary element method (BEM) formulation. The mixed‐mode stress intensity factors (SIFs), KI, KII and KIII, are calculated.
Design/methodology/approach
A 3D dual‐BEM or single‐domain BEM is employed to solve the fracture problems in a linear anisotropic elastic cuboid. The transversely isotropic plane has an arbitrary orientation, and the crack surface is along an inclined plane. The mixed 3D SIFs are evaluated by using the asymptotical relation between the SIFs and the relative crack opening displacements.
Findings
Numerical results show clearly the influence of the material and crack orientations on the mixed‐mode SIFs. For comparison, the mode‐I SIF when a horizontal rectangular crack is embedded entirely within the cuboid is calculated also. It is observed that the SIF values along the crack front are larger when the crack is closer to the surface of the cuboid than those when the crack is far away from the surface.
Research limitations/implications
The FORTRAN program developed is limited to regular surface cracks which can be discretized by the quadrilateral shape function; it is not very efficient and suitable for irregular crack shapes.
Practical implications
The evaluation of the 3D mixed‐mode SIFs in the transversely isotropic material may have direct practical applications. The SIFs have been used in engineering design to obtain the safety factor of the elastic structures.
Originality/value
This is the first time that the special nine‐node quadrilateral shape function has been applied to the boundary containing the crack mouth. The numerical method developed can be applied to the SIF calculation in a finite transversely isotropic cuboid within an inclined surface crack. The computational approach and the results of SIFs are of great value for the modeling and design of anisotropic elastic structures.

Propose a model that reports ethnocentrism, animosity, perceived quality and purchase intention in the evaluation of the country-of-origin effect for wine.
Abstract
Purpose
Propose a model that reports ethnocentrism, animosity, perceived quality and purchase intention in the evaluation of the country-of-origin effect for wine.
Design/methodology/approach
The sample for this study consisted of 154 students from the University of São Paulo Campus Ribeirão Preto and Piracicaba. Using scales already validated in the literature, a survey was carried out with 27 questions in the seven-point Likert format. The structural model was estimated using the partial least squares method.
Findings
It was verified that the country of origin positively influenced the purchase intention of wines, ethnocentrism positively influenced perceived quality, ethnocentrism positively influenced animosity, animosity negatively influenced the purchase intention and the country of origin positively influenced the perceived quality of the wine. It was verified that ethnocentrism did not influence purchase intention and the country of origin did not influence animosity.
Practical implications
As a managerial contribution, it helps managers to devise more effective strategies for the wine market.
Originality/value
An innovative model was proposed to investigate the role of animosity, ethnocentrism, perceived quality and purchase intention in evaluating the country-of-origin effect for wine.

Abstract
Purpose
In today’s Taiwan, sha-cha sauce is an indispensable ingredient for beef hot pot and stir-fried dishes. The purpose of this paper contextualizes the history of sha-cha sauce in Tainan, the oldest city in Taiwan, and argues that sha-cha sauce, introduced by Chaoshan immigrants, has contributed to new styles and habits of beef consumption tastes and habits in the post-1949 Tainan and beyond.
Design/methodology/approach
This paper uses documentary materials, oral interviews and diaries to explore the relationship between beef consumption and sha-cha sauce. It begins with an historical overview of Taiwan’s beef consumption during the Japanese colonial era (1895-1945). Then, it focuses on two Chaoshan business enterprises: the Bull-Head, which makes the world’s largest “canned sha-cha sauce,” and the Xiao Haozhou, a Tainan restaurant specializing in sha-cha beef hot pot. Finally, this study analyzes Xinrong Wu, a Tainan gentry whose diary entries from 1933 to 1967 documented the changing dietary habits of beef consumption among Taiwanese.
Findings
The Chaoshan migrants played an important role in introducing the sha-cha sauce to postcolonial Tainan, and this input bolstered the beef consumption among Taiwanese. The production of sha-cha provided a reliable source of income for these migrants in Tainan, and major businesses like the Bull-Head became the international brands of Taiwanese food products.
Research limitations/implications
The study, though limited to Tainan, reveals the symbiosis between popularization of sha-cha sauce and widespread beef consumption in Taiwan.
Practical implications
This study helps researchers examine the connection between Chinese migrations and food culture.
Originality/value
This paper is an original scholarly investigation of the relationship between food diet and Chaoshan migration in postcolonial Tainan.

Abstract
In recent years, three key topics under the big umbrella of business process improvement (BPI) have been continuous process improvement (CPI), business process reengineering (BPR), and business process benchmarking (BPB). Each has received much attention and has been supported by a considerable amount of literature and empirical research and findings from business consultants and academics. Within the manufacturing domain, these three topics have been accepted by many manufacturing process analysts striving to improve productivity and efficiency of companies. However, organization structures in manufacturing enterprises are complex and involve many different processes. Their needs may be quite different. One process may require an incremental improvement in critical areas or technology updating in its existing operation while others may need a total enterprise‐wide process revamp. In other words, CPI, BPR, and BPB’s usefulness and applicability may not be universal; one or a combination of the two or three may be more appropriate, depending on the process, organization and its environment. An improvement framework which incorporates the characteristics of the three approaches has been developed. This paper describes the methodology, SUPER, and its use in a real case study.

Abstract
The spectral boundary element method for solving two‐dimensional transient heat conduction problems is developed. This method is combined with the fast Fourier transform (FFT) to convert the solution between the time and frequency domains. The fundamental solutions in the frequency domain, required for the present method, are discussed. The resulting line integrations in the frequency domain are discretized using constant boundary elements and used in a Fortran boundary element program. Three examples are used to illustrate the accuracy and effectiveness of the method in both the frequency and time domains. First, the frequency domain solution procedure is verified using the steady‐state example of a semi‐infinite half space with a heat flux applied to a patch of the surface. This spectral boundary element method is then applied to the problem of a circular hole in an infinite solid subjected to a time‐varying heat flux, and solutions in both the frequency and time domains are presented. Finally, the method is used to solve the circular hole problem with a convection boundary condition. The accurary of these results leads to the conclusion that the spectral boundary element method in conjunction with the FFT is a viable option for transient problems. In addition, this spectral approach naturally produces frequence domain information which is itself of interest.
