The accuracy of the machining process is significantly impacted by the performance of hydrostatic bearings. This paper aims to analyze the influence of micro-textured on the performance of the hydrostatic bearing, and the performance of the bearing is improved by designing the arrangement of micro-textured.

Different designs have been used while creating micro-textured bearings. The finite element models of bearing with smooth and micro-textured were established and solved using the computational fluid dynamics method. The arrangement scheme of the micro-textured was evaluated by comparing the influence of the distribution position and arrangement of the micro-textured on the bearing performance.

To improve the performance of the bearing, the bearing capacity was significantly increased, and the friction coefficient of the bearing was decreased when the micro-textured was distributed in the form of an obtuse angle arrangement in the maximum pressure area of the bearing. The experimental findings validate the analysis method.

In this paper, the effect of irregularly arranged micro-textured on bearing performance is investigated to improve the bearing capacity and lubrication status.

The rampant toxic gaming environment in most major esports games has become a challenge in maintaining gamers’ loyalty to the game. Guided by the theory of stress and coping, this study aims to investigate how and under what condition esports gamers’ perceived risk of toxicity may affect game brand loyalty through the moderated mediation effects of game brand identification, self-efficacy, and perceived support from game brand.

The moderated mediation model was tested using the conditional process analysis (N = 311). The moderating effects of game brand identification on the mediated processes were tested in the model.

The authors found that self-efficacy and perceived support from game brand were critical mediators between the perceived risk of toxicity and game brand loyalty. However, these mediating effects varied depending on the level of game brand identification.

This study took the step forward by theorizing and empirically examining the relationship between perceived risk of toxicity and consumption outcome by considering both internal and social coping resources and game brand identification, among Generation Z and Millennial gamers in the esports context.

The shape of a product plays a crucial role in shaping consumer behavior. Despite the voluminous research on factors influencing consumers’ shape preferences, there remains a limited understanding of how the busy mindset, a mentality increasingly emphasized by marketing campaigns, works. This study aims to fill this gap by exploring the relationship between a busy mindset and the preference for angular-shaped versus circular-shaped products and brand logos.

This research consists of seven experimental studies using various shape stimuli, distinct manipulations of busy mindset, different assessments of shape preference and samples drawn from multiple countries.

The findings reveal that a busy mindset leads to a preference for angular shapes over circular ones by amplifying the need for uniqueness. In addition, these effects are attenuated when products are scarce.

This research represents one of the pioneering efforts to study the role of a busy mindset on consumers’ aesthetic preferences. Beyond yielding insights for practitioners into visual marketing, this research contributes to the theories on the busy mindset and shape preference.

Despite the negative effects of toxicity on various aspects of esports communities, gamers continue to enthusiastically show their pride and engage with the game. Based on the stress and coping theory, the current study aims to shed light on how esports gamers cope with toxicity to develop toxicity tolerance by the mediation effect of positive reappraisal coping strategy.

A total of 456 gamers were included in the analysis. Structural equation modeling was performed to evaluate the hypothesized model. Gender differences in the toxicity-coping process were investigated using multi-group analysis.

The findings revealed the full mediation effect of positive reappraisal on the relationship between toxicity and toxicity tolerance, especially for male gamers. The empirical evidence of this study contributes to theorizing the transformative role of positive reappraisal in developing positive consumption outcomes when esports gamers experience toxicity in the game. The multi-group analysis provided further insights into differentiating the applicability and effectiveness of positive reappraisal based on gender.

The findings contributed to sport management and communication literature by allowing researchers and practitioners to move beyond a preventive coping mindset by facilitating a positive coping environment that encourages gamers to interpret the conversation and messages in a more positive manner.

This paper is about equity crowdfunding syndicates as a form of entrepreneurial finance and looks specifically at the lead investors' human capital and their ability to raise funds.

The authors develop regressions on a unique hand-collected dataset of 178 lead investors taken from the US-based platform AngelList.

Results indicate that lead investors' specialized human capital has a positive effect on their syndicate fundraising performance. However, it does not find a significant effect of general human capital. It also finds that specialized human capital is mediated by the reputation of the lead investor on the platform.

This study extends human capital theory in the crowdfunding context by providing a more comprehensive portrait of human capital and in doing so, shifts the focus from an entrepreneur to an investor perspective, an approach much neglected in the crowdfunding literature.

This study advances the current knowledge on crowdfunding as it is one of the first to understand syndicate investment as an innovative and alternative platform-based financial channel. It also contributes to the current debate on the role of human capital in crowdfunding and more generally to entrepreneurial finance.

First, spot check the trial production impellers and obtain three indexes that reflect the assembly quality of the impellers. Then, analyze the parameters that affect the assembly quality of the impeller using grey relational analysis (GRA), establish a model for the assembly quality of the range hood impeller based on the generalized grey relational degree and identify the main parameters. After that, analyze the transmission structure of automation assembly workstation, identify the reasons that affect parameters and propose improvement plans. Finally, a trial production is conducted on the automation assembly workstation after adopting the improved plan to verify the quality model of impeller automation assembly.

The research shows that compared to manual assembly, the automation assembly quality of the impeller using GRA model has been improved, shortening the debugging cycle of the newly developed assembly workstation.

The newly developed automation equipment will have some problems in the trial production stage, which often rely on the experience of engineers for debugging. In this paper, the automation assembly quality model of range hood impeller based on GRA is established, which can not only ensure the quality of finished impeller but also shorten the debugging cycle of the equipment. In addition, GRA can be widely used in the commissioning of other automation equipment.

This study has developed a set of impeller automation assembly workstation. The debugging method in the trial production stage is beneficial to shorten the trial production time and improve the economic benefits.

The main purpose of this study is to explore the effect of three dimensions of “home feeling” – home-as-practical, home-as-social and home-as-attachment – on the online rating of homestays and additionally considers the accommodation’s attribute performance and level of sharing.

To achieve the research aims, more than 9,738,335 items of user-generated content concerning 743,953 Airbnb listings covering 35 cities were collected as the study data. These data are analyzed through hierarchical regression.

The results show that all three dimensions of home feeling positively affect the online rating; all three dimensions negatively moderate the relationship between attribute performance and online rating; the size of the moderating effect of each dimension on the relationship between attribute performance and online rating gradually increases in the order home-as-practical, home-as-social and home-as-attachment; and as the level of sharing increases, the moderating effect of home feeling on the relationship between attribute performance and online rating diminishes.

This study contributes to the literatures on the role of home feeling in homestays, the online rating of homestays and the motivations of guests who choose different room types. The findings of this study can help hosts better understand the formation of online rating of homestays, make targeted improvements in rooms and services and create a home feeling for specific degrees of sharing. This in turn will help them to improve the online rating of their homestays, establish an excellent online reputation and, ultimately, increase sales.

This study advances knowledge by confirming three dimensions of home feeling not only have direct positive impacts on online rating but also mitigate the impact of attribute performance on online rating. This effect differs significantly in magnitude with the degree of sharing.

The purpose of this study was to test the mediating effect of psychological entitlement in the relationship between perceived overqualification (POQ) and workplace ostracism. In addition, the authors posited that POQ would interact with task interdependence to influence psychological entitlement and indirectly affect workplace ostracism.

Using data collected in three waves from 450 workers in a state-owned enterprise, the authors tested the proposed moderated mediation model.

POQ increased workplace ostracism through the mediation of psychological entitlement. Moreover, task interdependence buffered the positive effect of POQ on psychological entitlement.

When recruiting, managers should be careful about hiring employees who are too above the job requirements to lessen employees' POQ and lower its negative impact. In addition, they could reduce the feeling of being ostracized for overqualified employees through increasing task interdependence.

Existing research on antecedents of workplace ostracism had mainly focused on the ostracizers, while largely ignoring the victims. Moreover, of the few studies on the victims of ostracism, most focused on inherent employee characteristics or external environmental factors, while little research attention has been given to employees' subjective perceptions. The present study is among the first to examine whether employees' POQ and individuals' self-perception that their skills, knowledge and abilities exceed the job requirements would lead to being ostracized and if so, how and when.
