This paper aims to synthesize the existing literature on virtual reality (VR) in the luxury fashion industry, discuss the current practical applications of VR technologies and review previous research undertaken in the luxury fashion field.

This paper conducts a systematic review and thematic analysis of existing literature to evaluate current research concerning VR and the luxury fashion industry. This search initially returned a total of 1,131 sources. After establishing and applying criteria of exclusion and inclusion, a total of 46 articles were selected for the thematic analysis.

Five major themes were identified, including virtual luxury fashion consumption, VR in marketing communication, virtual try-on, VR retail (including virtual fashion retail spaces) and virtual worlds (including customers’ virtual representation as avatars). The importance of these themes for the study of VR in luxury fashion is supported by relevant studies in the literature.

Whilst research into VR use within luxury fashion has increased recently, it remains fragmented. Given the absence of a comprehensive review addressing this topic within the literature, this paper will help scholars and fashion brands better understand the effects of VR on the luxury fashion industry. By integrating current practice and existing research, this paper contributes to a better understanding of how and where VR is used in luxury fashion contexts.

Supervisor incivility and organizational gossip are two examples of dark organizational behaviors. Norm of reciprocity theory suggests that employees may develop revenge intentions after exposure to such behaviors while attributing blame to others. This study aims to empirically investigate the mediating effect of blaming others on the impact of supervisor incivility and negative organizational gossip on revenge intention.

Confirmatory factor analysis (CFA) was performed to test the measurement model. Structural equation model was used to test the research hypotheses based on data gathered in Turkey from restaurant employees in Mersin Marina selected by convenience sampling. Data set that consists of 239 questionnaires was subjected to CFA.

The findings show that negative organizational gossip and supervisor incivility increase to employees’ revenge intentions, and blaming others mediates the impact of supervisor incivility and negative organizational gossip no employees’ revenge intentions. In addition, blaming others mediates the impact of supervisor incivility and negative organizational gossip on employees’ revenge intentions.

Empirical study has not been encountered related to dark behaviors of (especially gossip, incivility, blame and revenge intention) restaurant managers and employees as a holistic model. Therefore, this paper contributes to organizational behavior literature. Moreover, this paper suggests to restaurant managers for supply to organizational peace.

This study aims at proposing an approach for optimizing the shape of the top piston ring face for minimum friction force using an inverse method. The shape of the top piston ring face determines the amount of oil distribution in the interface of the ring and liner. Therefore, the shape has a significant impact on the tribological performance of this interface.

The shape of the ring face is represented by a polynomial function and is based on the load analysis of the ring. The optimization of the shape was performed using the Sequential Quadratic Programming method. The minimizing of the friction parameter at the interface was considered during the solving process to obtain an optimum ring shape.

The optimized high degree of the shape of the ring face could lead to a reduced friction parameter. The proposed method could be applied for the tribological design and optimization of the piston rings.

There still need effort to investigate the effect of design parameters (e.g. property of lubricant)on the optimization of the ring face.

The subject matter is important and the method has practical value.

The contact and lubrication performances, which were previously estimated assuming a Gaussian surface, are insufficient due to the non-Gaussian surface characteristics of the honing liner. The purpose of this study is to analyze the liner honing surface and examine its effects on the contact and flow performance.

The fast Fourier transform (FFT) method was used to generate the liner honing texture. Subsequently, an elastoplastic contact model based on boundary element theory was constructed and simulated for the honing surface. The results were compared with those obtained using a Gaussian surface. In addition, flow factors of the honing surfaces were also compared.

The contact pressure and flow factors demonstrate significant disparities when dealing with non-Gaussian surfaces. In the deterministic model, the pressure exhibits considerably diminished magnitudes and a more evenly distribution. Moreover, when the gap between surfaces is narrow, the discrepancy in flow factor across different directions on the real honing surface becomes more prominent compared with the Gaussian surface.

The model incorporates the influence of the non-Gaussian honing surface, thereby enabling more accurate prediction.

Friction and wear are very important factors in predicting the performance of journal bearings, particularly under heavy load in start-up processes. However, there are few relevant studies on the numerical model. This study aims to establish a transient-mixed lubrication model to predict the performance of journal bearings, focusing on the friction and wear behavior under heavy load during start-up.

The average Reynold equation, three-dimensional energy equation, shear stress model for friction and Archard model for wear are coupled in the transient model by finite difference method. The linear wear simulation method is bought out to reduce the update times and the calculation time.

The different start-up accelerations and linear wear times set are compared and discussed, which indicates a reasonable start-up acceleration is necessary for journal bearings under heavy load during start-up, and setting linear wear times is an effective method to reduce the simulation time significantly. Furthermore, the wear profile in the start-up process spreads in both the clearance and circumferential directions, but mainly in the clearance direction, which increases the minimum film thickness and affects the friction performance.

This study is of great significance for the numerical prediction of the transient performance of journal bearings during start-up considering friction and wear.

Drawing on knowledge-based view, social exchange theory and leader-member exchange, this study examines how exploitative leadership (EL) influences knowledge management (KM), its processes, and further investigates the moderating role of organisational citizenship behaviours (OCB) on the relationship between EL and KM.

Using a quantitative approach, survey data were collected from 356 faculty members in Iraqi public universities, and the direct and moderating relationships were assessed through Hierarchical regression by PROCESS v.3.3 macros in SPSS.

The study found a significant negative impact of EL on KM, including its processes, especially on knowledge utilisation. The assessment also revealed that OCB has a significant moderating impact on EL, particularly its effect on knowledge creation.

The empirical insights of the study are valuable and precious for policymakers, managers and academics in education sectors of developing countries, to enrich their managerial and scientific performance through addressing EL behaviours while considering the moderating effect of OCB.

The relevance of the study stems from the scarcity of research on EL, while studies on the negative behaviours of leaders as a predictor of KM process failures are significantly limited. Additionally, studies on the moderating impact of OCB on the linkage between EL and KM processes remain limited. This study is one of the earliest studies that investigate these inter-relationships amongst EL, OCB and KM processes.

Due to customers' extensive avoidance behavior, social commerce may be less successful than anticipated. This study investigates the underlying mechanism and antecedents that influence customers' avoidance of peer-generated advertisements.

Based on the general framework of avoidance behavior, we propose a theoretical model for the context of a mobile social network, with tie strength as the user-related factor and violation of shared language, advertisement relevance and information overload as contextual variables. Using survey data collected from 334 customers on WeChat, we empirically examine the research model and hypotheses.

Tie strength and advertisement relevance are negatively associated with avoidance behavior, whereas information overload and violation of shared language have significantly positive effects. Furthermore, tie strength weakens the negative relationship between violation of shared language and avoidance behavior but strengthens the positive relationship between advertisement relevance and avoidance behavior.

The findings extend understanding of advertisement avoidance behavior and can guide practitioners' improvement of advertising efficiency in mobile social networks.

The research goal is to understand what factors affect users' knowledge and information learning and sharing on social media platforms. This study focuses on the impact of platform characteristics on users' behavior. Specifically, the purpose of this study is to investigate (1) what factors affect users' learning and dissemination of knowledge and information on social media platforms, (2) whether knowledge and information learning behavior will have a positive effect on sharing behavior and (3) try to establish an impact model of users' learning and sharing behavior about knowledge and information.

This study proposes an impact mechanism model to test these hypotheses. To achieve this, the authors collected data from 430 users who have used the social media platforms to acquire and share knowledge and information to test the hypothesis. The tools SPSS 26.0 and AMOS 23.0 were used to analyze the reliability, validity, model fits and structural equation modeling.

The results show that the learning of knowledge and information can influence the sharing behavior on social media platforms. Users' platform-based trust and platform-based satisfaction affect their knowledge and information learning and sharing on the platform. Factors affecting users' trust in social platforms include privacy protection effectiveness and network effects. And, perceived usefulness and perceived ease of use are related to users' satisfaction with social media platforms.

This study constructs an impact model on the learning and sharing of knowledge and information. The model takes the information system continuance model as the theoretical framework and integrates other factors, including the network effect, the effectiveness of privacy protection and trust. Most of the hypotheses of this research were confirmed. The conclusions provide practical guidance for the dissemination of knowledge information and platform management.

The purpose of this study is to investigate the effects of the axial piston pin motion on the tribological performances of the piston skirt and cylinder liner vibration for an internal combustion engine (ICE) under different operation conditions.

The dynamic equation for the piston incorporating into axial piston pin motion is derived first. Then, the proposed equation and associated lubrication equations are solved using the Broyden algorithm and difference method, respectively. Moreover, the axial motion of the piston pin and its slap on the cylinder liner are studied under different operation conditions.

The axial piston pin motion leads to an overall increase in the friction power consumption. Increments in the ICE speed and lubricant viscosity can augment the axial pin motion and cylinder liner vibration, especially in the power stroke. The said increments cause the instability of the piston motion in the cylinder. The axial motion of piston pin can be restrained through the eccentricity of the piston pin close to the thrust side of the cylinder liner.

This study conducts detailed discussions of the effect of axial piston pin motion on tribological and dynamic performances for piston skirt-cylinder liner system of an internal combustion engine and gives a helpful reference to analyses and designs of internal combustion engines.

This study aims to examine how cultural tightness at the national level and individual level influences consumer attitudes toward a brand's wrongdoing depending on the brand's country of origin and severity of the transgression.

Employing data from two tight-culture countries (China and South Korea) and a loose-culture country (the USA), two experiments were conducted to examine the proposed hypotheses.

The authors found that although consumers across cultures universally punish strong (vs weak) transgressions more severely, consumers in a tight-culture country, China, are more forgiving of a local (vs foreign) brand in both strong and weak transgression conditions, and forgiveness is higher for the strong transgression. Moreover, this buffering effect observed for Chinese consumers is stronger for those with high personal cultural tightness in the strong transgression condition. However, it emerges only in the weak transgression condition for South Korea, another tight-culture country. As hypothesized, no buffering effect for a local brand was found in a loose-culture country, the USA. Consumers from a loose culture assess transgression severity independently, and the punishment is harsher for strong transgressions than for weak transgressions.

This study fills a research gap by revealing that consumers from tight (vs loose) cultures would react differently to brands following a transgression depending on the brand's country of origin. It provides implications by examining how national-level and individual-level cultural tightness jointly affect post-transgression attitudes. It also presents a more nuanced perspective that the local brand's buffering effect is contingent on the degree of tightness and severity of transgression, even in similar culturally tight countries.
