Abstract

Purpose

Drawing on social exchange theory and a cultural perspective, this study examines the relationship between workplace ostracism and job engagement by focusing on the mediating role of felt obligation and the moderating role of collectivism.

Design/methodology/approach

A two-wave survey was conducted over four months in a private service business in China. The participants comprised 108 Chinese employees.

Findings

The results indicate that workplace ostracism has a negative relationship with job engagement through a reduced sense of felt obligation. Collectivism strengthens the main effect of workplace ostracism on felt obligation and its indirect effect on job engagement via felt obligation.

Research limitations/implications

This study contributes to understanding of the internal mechanism of the workplace ostracism–job engagement model by identifying the mediating role of felt obligation. It also emphasizes that collectivist cultures can enhance the effects of workplace ostracism. However, the generalizability of our findings may be limited due to this cultural factor.

Practical implications

Our findings show that workplace ostracism plays a significant role in reducing job engagement. Therefore, it is essential to reduce the incidence of ostracism in the workplace.

Originality/value

By addressing the previously unexplored mechanism that mediates the relationship between workplace ostracism and job engagement, this study provides new directions for research on workplace ostracism and job engagement.

Abstract

Purpose

The purpose of this study is to explore how government subsidies influence technology innovation in new-energy enterprises in the new era of Industry 4.0. Specifically, this study investigates the mediating effect of digital transformation and the moderating effect of a top management team (TMT) with digital experience.

Design/methodology/approach

Using a sample of 225 listed new-energy companies, with annual information, patent data, and financial data for the years 2010–2020, this study employs panel fixed effect regression models to obtain the results.

Findings

This study finds strong evidence that government subsidies promote the technology innovation of new-energy enterprises, and digital transformation partially mediates the effect of government subsidies on technology innovation. In addition, a TMT's digital experience moderates the effect of government subsidies on digital transformation, but has no significant moderating effect on the relationship between digital transformation and technology innovation. Further analysis shows that subsidies make a sustained contribution to both digital transformation and technological innovation over the next two years. The digital subsidies have a stronger role in promoting digital transformation and further technological innovation through digital transformation.

Practical implications

The Chinese government needs to continue to intermittently increase subsidies for new-energy enterprises, and focus on guiding enterprises' digital transformation. Chinese new-energy enterprises should pay attention to the importance of having TMTs with digital experience, make full use of government subsidies, actively implement digital transformation, and improve their innovation levels.

Originality/value

A new conceptual framework is proposed to examine the relationships between government subsidies, digital transformation, a TMT's digital experience, and technology innovation. This paper provides an important theoretical basis and practical reference for improving the technology innovation ability of Chinese new-energy enterprises, and the high-quality development of renewable energy in the context of Industry 4.0.

Abstract

Purpose

Previous research has examined the effects of discrete affects on voice; however, the role of trait and state affects in voice literature has received little attention. This study aims to address this important issue from a conservation of resources perspective, by exploring the influence of daily positive affect and emotional resistance to change on the voice of employees and their resulting work outcomes.

Design/methodology/approach

The study collected data about 285 daily episodes from 57 employees over five consecutive days, using an experience sampling method (ESM) through mobile surveys. The study found that emotional resistance to change was negatively related to employee voice and in-role performance.

Findings

Voice mediated the negative relationship between emotional resistance to change and in-role performance. The study also found that daily positive affect buffered the negative effects of emotional resistance to change on voice.

Originality/value

These findings extend the research concerning affect and voice; the study provides integrative insight into how affect dynamically influences organizations.

Abstract

Purpose

Thermal performances are key factors impacting the operation of angular contact ball bearings. Heat generation and transfer about angular contact ball bearings, however, have not been addressed thoroughly. So far, most researchers only considered the convection effect between bearing housings and air, whereas the cooling/lubrication operation parameters and configuration effect were not taken into account when analyzing the thermal behaviors of bearings. This paper aims to analyze the structural constraints of high-speed spindle, structural features of bearing, heat conduction and convection to study the heat generation and transfer of high-speed angular contact ball bearings.

Design/methodology/approach

Based on the generalized Ohm’s law, the thermal grid model of angular contact ball bearing of high-speed spindle was first established. Next Gauss–Seidel method was used to solve the equations group by Matlab, and the nodes temperature was calculated. Finally, the bearing temperature rise was tested, and the comparative analysis was made with the simulation results.

Findings

The results indicate that the simulation results of bearing temperature rise for the proposed model are in better agreement with the test values. So, the thermal grid model established is verified.

Originality/value

This paper shows an improved model on forecasting temperature rise of high-speed angular contact ball bearings. In modeling, the cooling/lubrication operation parameters and structural constraints are integrated. As a result, the bearing temperature variation can be forecasted more accurately, which may be beneficial to improve bearing operating accuracy and bearing service life.

Large scale is a trend of the ball mill, so the loads on their bearings become very large, bearing operating conditions turn into more severe. The moment of inertia to their pivot of the pad increase significantly, so it leads to the difficult of the pad attitude adjustment and makes the pad tilting angles time response slow, the key factor to effects attitude adjustment is the oil film moment to the pad pivot at unbalance position. the oil film moment and its effect factors must be studied in the design of the bearing used in ball mill.

Design/methodology/approach

Models about the lubrication of multi-pocket pivoted pad hydrostatic bearing is established, the complicated relationship of the oil flow rate between the oil pockets are taken into account. Finite differential method is used to solv the model, and theroy of finite element method is use to calculate the oil flow rate out of the pocket edges. Newton’s methods are used to determine the pressure of pockets.The pad tilting moment to its pivot is numerically analyzed.

Findings

The tilting moment to its pivot is set as an indicator of the ability for a pad to adjust its attitude. The effects of the diameter of throttling capillary and the pocket area on the attitude adjusting capacity is studied. Relations between the attitude adjustment capacity for a pad and there effects factors are presented.

Practical implications

The methods and results have the special reference to the design and operation of multiple pockets tilted pad hydrostatic journal bearing.

Originality/value

Abstract

Drawing on the social cognitive theory, this study investigated the effect of mentors' drinking norms on their protégés' alcohol misuse by focusing on the mediating role of conformity drinking motives and the moderating role of moral disengagement. We conducted a three-wave survey of 148 mentor–protégé dyads and found that mentors' drinking norms were positively related to their protégés' alcohol misuse and that this relationship was fully mediated by conformity drinking motives. Moreover, the moderated mediation model revealed that moral engagement strengthens the main effects of mentors' drinking norms on conformity drinking motives and the indirect effects of mentors' drinking norms on protégés' alcohol misuse via enhanced conformity drinking motives. The theoretical and practical implications are discussed.

Abstract

Research on mentorship has been dominated by the West and little is known about the cultural variations of the mentoring phenomenon in Asian countries. A richer understanding of the cultural context that is more attuned to mentoring experience in Asia can help to improve workplace experience, in general, for those working in and for those who intend to work in the region. This chapter captures the important theoretical lenses in the mentoring literature, and also provides a clear demarcation between negative mentoring and dysfunctional mentoring. This is followed by contextualizing mentoring as per four of Hofstede's six cultural dimensions by dwelling on mentoring experience in countries such as China, India, Pakistan, Japan, South Korea and Taiwan. It is hoped that this chapter will pave the way for further research, which may be a precursor for theory development.

Abstract

Purpose

The purpose of the study is to evaluate the severity of public events in real time from the perspective of social media and to construct the early warning mechanism of public events.

Design/methodology/approach

This study constructed the severity assessment system of public events from the dimensions of the netizens' role, the Internet media's role, the spread of public events and the attitudes and feelings of netizens. The method of analyzing the influence tendency of the public event severity indicators was proposed. A total of 1,107,308 microblogging entries regarding four public events were investigated. The severity of public events was divided into four levels.

Findings

It is found that serious public events have higher indicator values than medium level events on the microblogging platform. A quantitative severity classification standard for public events was established and the early warning mechanism of public events was built.

Research limitations/implications

Microblogging and other social media platforms provide rich clues for the real-time study and judgment of public events. This study only investigated the Weibo platform as the data source. Other social media platforms can also be considered in future.

Originality/value

Different from the ex-post evaluation method of judging the severity of public events based on their physical loss, this study constructed a quantitative method to dynamically determine the severity of public events according to the clues reflected by social media. The results can help the emergency management departments judge the severity of public events objectively and reduce the subjective negligence and misjudgment.

Abstract

Purpose

Based on the organizational learning theory, this study regards market orientation as market-based learning and seeks to advance insight into how proactive and responsive market orientations affect two kinds of open innovation strategies, sourcing and selling. A firm’s information and communication technology (ICT) capability is considered an essential moderator in these relationships.

Design/methodology/approach

This study adopted a quantitative design and used the questionnaire survey method to collect data. The authors finally collected data on samples in China. Multiple regression analysis was used to test the hypotheses.

Findings

The results show that proactive and responsive market orientations act as antecedents of open innovation, showing linear and curvilinear relationships between them. Specifically, responsive market orientation positively affects selling, and proactive market orientation positively affects sourcing. Responsive market orientation has an inverted U-shaped relationship with sourcing, and proactive market orientation has a U-shaped relationship with selling. In addition, ICT capability strengthens the positive effects of market orientation on open innovation and weakens the negative effects.

Originality/value

Drawing on organizational learning theory, this study provides a novel perspective to explain the complex mechanism between market orientation and open innovation. This study also explores the moderating role of ICT capability in this process, which advances research on how to select open innovation strategies under different conditions.
