Abstract
Purpose
Drawing on identity theory and the symbolic interactionism perspective of identity theory, this study aims to construct a moderated mediation framework to test the effects of perceived overqualification (POQ) on knowledge sharing (KS) through professional identity threat (PIT) and the moderating role of coworkers' help-seeking behavior (CHSB).
Design/methodology/approach
This paper uses a quantitative multistudy research design with a combination of a scenario experiment (Study 1) and a two-wave field study among 220 supervisor-subordinate dyads at a power company in China. Using analysis of variance, confirmatory factor analysis (CFA) and bootstrapping method, the authors validated the research hypothesis.
Findings
In the scenario experiment study (study 1), the authors find that POQ is positively related to PIT and that CHSB negatively moderates the positive impact of POQ on PIT. The field study (study 2) replicated the above findings and found that PIT mediates the negative effect of POQ on KS. In addition, CHSB negatively moderates the mediating role of PIT between POQ and KS.
Originality/value
First, the current study extended the nomological network of POQ research by examining its influence on employees' KS. Second, this study empirically investigated the mediating role of PIT, which provided a new explanatory mechanism for the influence of POQ. Finally, this study demonstrates the moderating role of CHSB—a situational factor that has been ignored in previous studies.

Abstract
Purpose
The present study was conducted to investigate the relationship between team-level inclusive leadership perceptions, team thriving, and team proactivity as well as the moderating effect of team power distance on these relationships.
Design/methodology/approach
A two-wave survey study of 365 manufacturing employees comprising 85 teams in an organization in Eastern China was used to test the hypotheses.
Findings
The findings indicate that inclusive leadership stimulates collective thriving, which then promotes team proactivity. In addition, team power distance negatively moderates the relationship between inclusive leadership and collective thriving, as well as the indirect effect of inclusive leadership on team proactivity via collective thriving.
Originality/value
This study is one of the first to investigate the effects of inclusive leadership at the team level, and answers recent calls to investigate the mechanisms linking leadership-related constructs to team-level proactivity. The authors also identify an important boundary condition to the effects of inclusive leadership in team power distance.

Abstract
Purpose
This study aims to report the development and experimental evaluation of two kinds of PANI@semiconductor based photocathodic anti-corrosion coating, for application on stainless steel substrates.
Design/methodology/approach
PANI was in situ chemical polymerized on TiO2 and BiVO4 particles, and FT-IR and SEM/EDS were used to understand the characteristics and elemental distribution of the composite particles. Composite coatings, which consisted of epoxy, PANI@TiO2 or PANI@BiVO4 and graphene, were prepared on the 304L stainless steel. Photoelectrochemical response measurement, electrochemical tests and immersion tests were used to assess the anti-corrosion performance of the prepared coatings in 45°C 3.5 wt.% NaCl solution. And the corrosion protection mechanism was further explained by combining with surface observation.
Findings
The photoelectrochemical response tests revealed the good photocathodic effect of the coatings, and the reversible oxidation-reduction properties of PANI (pseudocapacitive effect) leading to the repeated usage of the coatings. Consequently, the anti-corrosion mechanism of the composite coating is attributed to the physical barrier effect of the coating, the anodic protection effect of PANI and the photocathodic and energy store effect.
Originality/value
These kind coatings could prevent corrosion from day to night for stainless steel, which has great engineering application prospects on stainless steel corrosion protection.

Abstract
Purpose
The purpose of this paper is to study the relationship between high temperature oxidation and temperature rise rate of engine oil attempted to explore a new indicator to evaluate oil degradation.
Design/methodology/approach
Accelerated oxidation test combined with molecular simulation and road test is carried out in this paper. The temperature rise characteristics of mineral oil and synthetic oil under different oxidation temperatures (140°C, 155°C and 170°C) and time (50 h, 100 h, 150 h and 200 h) were determined by accelerated oxidation. The mechanism of temperature change characteristics of used oils was analyzed with molecular simulation. Two experimental vehicles carried six road tests with synthetic and mineral oil.
Findings
The results of this study show that the temperature rise rate of oxidized mineral and synthetic oil is higher than the new oil. The temperature rise rate is proportional to the oxidation time and oxidation temperature. The synthetic engine oil temperature rise rate is lower than that of the mineral engine oil. The same result was obtained in road tests. Molecular simulation verifies that small molecules were generated after oil oxidation which results in intermolecular friction and increased heat generation.
Originality/value
This paper indicates that temperature rise rate has potential to be taken as an indicator to evaluate oil oxidation which provides a new way for engine oil analysis.

Abstract
Purpose
People’s economic behaviors are often embedded in their social networks. Based on social embeddedness theory, this study investigates how customers’ social network embeddedness (structural and relational embeddedness) affects their online referral intentions through four studies.
Design/methodology/approach
This study adopted a vignette experimental design and used both offline and online channels to collect data. The respondents were undergraduate students and consumers, covering different age groups and occupation types. We used the ANOVA and bootstrap methods of SPSS to conduct data processing and hypothesis testing.
Findings
We found that when fewer (vs more) people in a customer’s social network participated in reward referral programs (RRPs), the customer’s online referral intention was also lower because of higher perceived social costs and lower perceived control. However, when the tie strength, reciprocity and normative influence between customers and people who have participated in RRPs were high, customers’ online referral intention also increased, ignoring the influence of participants’ network size. In these relationships, perceived social costs and perceived control played important mediating roles.
Practical implications
The results provide practical implications for enterprises to develop efficient RRPs in the context of the increasing popularity of the mobile Internet and intelligent terminals.
Originality/value
This study offers insights into the influence mechanism of social network embeddedness on referral likelihood, contributing to the field of RRPs and social embeddedness theory.

Abstract
Purpose
Considering the rapid adoption of social media among consumers and organizations, this study intends to examine the impact of online bundle promotions and contextual interactions on impulse buying as consumers encounter them synchronously. Hence, a research model is proposed with the integration of perceived transaction value, perceived acquisition values, top reviews information, impulse buying tendency and emotional intelligence following the stimulus-organism-response framework, promotional framing effect, and theory of selective attention.
Design/methodology/approach
Data were collected from the active social media members of organization pages and selling groups by utilizing the self-administered questionnaire. This study employed the partial least squares structural equation modeling to evaluate the data of 358 individuals.
Findings
Results reveal the positive impact of targeted constructs on the urge to buy impulsively with complementary partial mediation of impulse buying tendency. Besides, emotional intelligence dissuades users' impulse buying tendencies, but unexpectedly, its moderating effect is insignificant. Further, importance-performance map analysis highlights the highest importance of impulse buying tendency and better performance of perceived transaction value for the urge to buy impulsively.
Originality/value
This research is one of the early studies to explore the influence of social media advertising and contextual social factors (e.g. bundle offers and top reviews information) on impulse buying with the moderation of emotional intelligence and mediation of impulse buying tendency. This research is imperative for scholars and managers with pertinent suggestions to arouse impulse buying.

Abstract
Purpose
Based on social identity theory and parasocial interaction theory, this paper investigates the psychological influence mechanism of social media green influencers (GIs) on users' green consumption intention (GCI). It also examines the effects of users' environmental concern (EC), follow status (follower/non-follower), and nationality (Chinese/Pakistani).
Design/methodology/approach
This study uses convenience and exponential non-discriminatory snowball sampling to collect 393 valid data from China and Pakistan. Research hypotheses are tested using Smart-PLS 4.0.
Findings
The results confirm that parasocial relationships (PRs) and interactions (PIs) significantly influence green influencers' identification (GII) and green self-identification (GSI), which then positively affect green life attitudes (GLA) and ultimately promote GCI. Unsurprisingly, it proves EC moderates the relationship between GLA and GCI. Additionally, users' follow status (follower/non-follower) and nationality (Chinese/Pakistani) do not significantly moderate the hypotheses proposed in the study.
Originality/value
This study enriches the research on GIs and the psychological influence mechanism of GCI by combining media communication and consumer behavior. Furthermore, it provides new insights into the moderating role of social media users’ follow status and nationality.

Abstract
Although multiple effective vaccines against the COVID-19 pandemic have been discovered, produced and deployed worldwide at exceptional rates, multiple countries have been left out due to numerous reasons, and the vaccination rates among these countries have been dismally low, while at the other end, some nations were able to inoculate almost all of their people. There have been studies concerning this issue, trying to understand the factors causing such inequity, and most of them look at socio-economic conditions like income and the behavioural factor of vaccine acceptance. This chapter, however, emphasises the role of trade and the global value chains (GVCs) in providing countries access to vaccines, which are being manufactured in a distributed system of production stages. The main concerned variables are vaccination rates and the GVC participation measure. Such analysis could help us understand whether being part of the production chain gives the countries an advantage in accessing the vaccine stocks, and the results suggest that the GVC participation rate does have an effect on the vaccination rate of a country.
