PurposeThis study investigates how downward envy affects interpersonal conflict, workplace ostracism and displaced aggression in the mentoring context. It seeks to deepen our understanding of how these dynamics influence a mentor–protégé relationship.Design/methodology/approachEmploying a three-wave research design, this study uses a sample of 176 participants in mentoring relationships to test our proposed moderated mediation model.FindingsDownward envy can increase interpersonal conflict, workplace ostracism and displaced aggression. A mentor's social comparison orientation moderates these effects by amplifying the negative impacts of downward envy.Research limitations/implicationsThese findings have practical implications for both mentors and protégés.Practical implicationsThese findings have practical implications for both mentors and protégés.Originality/valueThis study contributes to the literature by focusing on downward envy within the mentoring context, yielding valuable insights to navigate mentoring experiences at work.

This longitudinal study explored how the relationship-building behavior of new employees induces career success. First, we proposed and tested a model based on mentoring and social capital theories, using mentor tie strength as a mediator to explain the association between relationship-building behavior and career success (career satisfaction and promotion). Next, we examined the moderating role of social network density and the moderated mediation effect. Survey data were collected at two time points from 252 new employees of a Chinese company. The results indicate that mentor tie strength mediated the association between relationship-building behavior and subjective career success (career satisfaction), and that social network density moderated the relationship between mentor tie strength and career satisfaction. Further, mentor tie strength mediated the association between relationship-building behavior and subjective career success (career satisfaction) when social network density was low; however, the mediation effect was nonsignificant when social network density was high. We discuss the theoretical and practical implications.

Based on the network embedding theory, cluster enterprises embedded in a social network can be divided into those based either on relational or structural embeddings. We use different indicators to measure how the characteristics of embeddedness in networks affect the interregional industry transfer stickiness and choice of transfer mode in China. We measure an enterprise's network and structure characteristics, and adopt a multiple linear regression using survey data to test the hypotheses. The results indicate that the greater the relationship strength and relationship stability, the stronger the transfer stickiness and the more inclined enterprises are to choosing the partial transfer mode. Similarly, the greater the network density and network centrality, the stronger the transfer stickiness and the more inclined enterprises are to choosing partial transfers. Conversely, the higher the network heterogeneity, the weaker the transfer stickiness, meaning that enterprises tend to choose the overall transfer mode.

PurposeDrawing 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/approachA two-wave survey was conducted over four months in a private service business in China. The participants comprised 108 Chinese employees.FindingsThe 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/implicationsThis 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 implicationsOur 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/valueBy 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.

AbstractIn the digital era, digital platforms are gradually changing the ways of life and social production and are becoming the centre of digital services in various industries. Additionally, they break the established institutional framework of social recognition and promote technological change and innovation. Thus, examining the quality of innovation facilitated by digital platforms has become an important area of research. This paper utilises China's 2011–2021 provincial panel data and examines digital platforms, resource mismatches and innovation quality within the same research framework. The direct, indirect and nonlinear effects of digital platforms on innovation quality are explored using the fixed effects model, intermediary effect model and dynamic threshold regression model. The findings indicate that digital platforms have a significant positive direct effect on innovative quality, and resource mismatches play intermediary and threshold roles in the process. These findings offer policy guidance for constructing robust digital platform ecosystems and enhancing innovation quality.

Wheat beer would be a desirable source of quality soluble dietary fibre (SDF). The effects of wort preparing parameters on SDF in wheat beer were investigated in the present work. Non-starch polysaccharides and polyphenols were greatly influenced by wheat malt percentage (WMP), while resistant protein (RP) was augmented by extending resting at 63°C. By verification test, the optimised parameters for high SDF wheat beer were WMP 55%, resting for 20 min at 43°C, 20 min at 50°C, and 20 min at 63°C, in which SDF was 2,178 mg/L. Most of SDF in wheat wort were retained in beer during fermentation and maturation (R = 0.561*). And SDF of wheat beer contained more RP and polyphenols. The present work contributes in controlling SDF content in wheat beer. It also has important guiding significance for beer brewing enterprises to develop new products rich in SDF.

<b><i>Objective:</i></b> Accumulated evidence suggests that ATP-binding cassette A1 transporter (ABCA1) contributes to secreting insulin in pancreatic β-cells and amyloid beta formation. This study aimed to investigate the association between three single nucleotide polymorphisms (SNPs) of ABCA1 and susceptibility to type 2 diabetes mellitus (T2DM) in a Han Chinese population. <b><i>Methods:</i></b> A total of 996 T2DM patients and 1,002 controls were included in the study. Three SNPs in the <i>ABCA1</i> gene, i.e., rs2230806 (R219K), rs1800977 (C69T), and rs9282541 (R230C), were genotyped by SNaPshot. A genotype model, an allele model, a dominant model, and a recessive model were used to assess susceptibility to T2DM. <b><i>Results:</i></b> There were significant associations between rs1800977 and T2DM in different genetic models (TT vs. CC, OR = 0.591 [0.446–0.793], <i>p</i> &#x3c; 0.001; T vs. C, OR = 0.835 [0.735–0.949], <i>p</i> = 0.006; recessive model, OR = 0.583 [0.449–0.756], <i>p</i> &#x3c; 0.001). There were also significant associations between rs9282541 and T2DM in different genetic models (CT vs. CC, OR = 1.690 [0.807–1.005], <i>p</i> = 0.048; T vs. C, OR = 1.756 [0.694–1.060], <i>p</i> = 0.029; dominant model, OR = 1.735 [0.715–1.034], <i>p</i> = 0.037). <b><i>Conclusion:</i></b> Our case-control study showed that the two SNPs rs1800977 and rs9282541 in the <i>ABCA1</i> gene are significantly associated with susceptibility to T2DM in our Han Chinese population. Study of further mechanisms should be performed before application to clinical therapy.
