The purpose of this paper is to investigate masculinity in Chinese social media marketing for global luxury fashion brands through two studies.

Study 1 compares physical characteristics of males in visually oriented US (Instagram) and Chinese (Weibo) social media posts promoting global luxury fashion magazine brands (e.g. Vogue, Cosmopolitan, GQ and Esquire). Study 2 examines the prevalence of and Chinese consumers’ responses (reposts, comments and likes) to different masculinities depicted in luxury fashion brand-sponsored Weibo posts.

Male portrayals for Chinese audiences feature more characteristics associated with emerging East Asian hybrid masculinities – “Little Fresh Meat” (LFM) and “Old Grilled Meat” (OGM) – than associated with global or regional hegemonic masculinity (i.e. the scholarly Wén and action-oriented Wu). Wén remains common in social media posts for luxury fashion goods, but LFM and OGM engender more consumer responses.

Chinese luxury fashion marketing depicts masculinity more similarly to other East Asian marketing than to Western marketing. Some luxury fashion brands are struggling for acceptance among Chinese youth. Luxury fashion marketers should incorporate hybrid rather than hegemonic masculinities to prompt more favorable responses among Chinese consumers, especially younger female target markets.

Growing female occupational and consumer power and shifting male employment from blue-collar to white-collar jobs have influenced media portrayals of masculinity. Social media marketing for luxury fashion brands demonstrates the prevalence and appeal of hybrid masculinities in China.

This review aims to give a critical view of the wheel/rail high frequency vibration-induced vibration fatigue in railway bogie.

Vibration fatigue of railway bogie arising from the wheel/rail high frequency vibration has become the main concern of railway operators. Previous reviews usually focused on the formation mechanism of wheel/rail high frequency vibration. This paper thus gives a critical review of the vibration fatigue of railway bogie owing to the short-pitch irregularities-induced high frequency vibration, including a brief introduction of short-pitch irregularities, associated high frequency vibration in railway bogie, typical vibration fatigue failure cases of railway bogie and methodologies used for the assessment of vibration fatigue and research gaps.

The results showed that the resulting excitation frequencies of short-pitch irregularity vary substantially due to different track types and formation mechanisms. The axle box-mounted components are much more vulnerable to vibration fatigue compared with other components. The wheel polygonal wear and rail corrugation-induced high frequency vibration is the main driving force of fatigue failure, and the fatigue crack usually initiates from the defect of the weld seam. Vibration spectrum for attachments of railway bogie defined in the standard underestimates the vibration level arising from the short-pitch irregularities. The current investigations on vibration fatigue mainly focus on the methods to improve the accuracy of fatigue damage assessment, and a systematical design method for vibration fatigue remains a huge gap to improve the survival probability when the rail vehicle is subjected to vibration fatigue.

The research can facilitate the development of a new methodology to improve the fatigue life of railway vehicles when subjected to wheel/rail high frequency vibration.

The aim of this paper is to demonstrate the application of optimal globalization grey relational analysis (GGRA) as a workable decision-making tool to prioritize emotional intelligence (EI) training needs of specific groups of academic leaders.

The study involved administrating the emotional skills assessment process to 50 academic leaders in the USA and 50 in Taiwan. Optimal GGRA was utilized to prioritize EI training needs of the two distinct groups of academic leaders.

Results of the optimal GGRA suggest that context-specific EI interventions focusing on enhancing weak areas of emotional competency are made possible through optimal globalization grey analysis.

Optimal GGRA is introduced as a valid decision-making technique for planning effective EI interventions. The results have implications for designing training courses targeting on enhancing weak areas of emotional competency.

The utility of optimal GGRA as a decision-making tool to prioritizing training needs for the two cultural groups of academic leaders in the study aims at going beyond the narrow psychometric perspectives of measurements on leadership potentials and reaching out to practical approaches to leadership development and training.

The large volume of big data makes it impractical for traditional clustering algorithms which are usually designed for entire data set. The purpose of this paper is to focus on incremental clustering which divides data into series of data chunks and only a small amount of data need to be clustered at each time. Few researches on incremental clustering algorithm address the problem of optimizing cluster center initialization for each data chunk and selecting multiple passing points for each cluster.

Through optimizing initial cluster centers, quality of clustering results is improved for each data chunk and then quality of final clustering results is enhanced. Moreover, through selecting multiple passing points, more accurate information is passed down to improve the final clustering results. The method has been proposed to solve those two problems and is applied in the proposed algorithm based on streaming kernel fuzzy c-means (stKFCM) algorithm.

Experimental results show that the proposed algorithm demonstrates more accuracy and better performance than streaming kernel stKFCM algorithm.

This paper addresses the problem of improving the performance of increment clustering through optimizing cluster center initialization and selecting multiple passing points. The paper analyzed the performance of the proposed scheme and proved its effectiveness.

The purpose of this paper is to fill important gaps by using the attachment theory and examining the effects of supervisors’ early family environment on their behaviors toward subordinates and subordinates’ responses.

The authors used samples of 334 supervisor–subordinate pairs from a manufacturing company.

The study finds that supervisors’ harmonious family environment has a positive influence on subordinates’ responses (job satisfaction, work-to-family enrichment and task performance) through the effect of supervisors’ positive working model and caregiving behavior. On the contrast, supervisors’ conflicting family environment has a negative influence on subordinates’ responses through the effect of supervisors’ negative working model and aggressive behavior.

Existing studies mainly explore the influence of organizational environment on supervisors’ treatment of their subordinates. However, few have examined the relationship between supervisors’ early family environment and their treatment of their subordinates.

The purpose of this paper is to fill important gaps by using the belongingness theory and examining the effects of individual-level workplace ostracism on members’ voice behavior and the effects of group-level workplace ostracism.

The authors used samples of 77 groups from a high-technological company.

Individual-level workplace ostracism is detrimental to group members’ promotive and prohibitive voice behavior, and group members’ belongingness mediates such effect; and group-level workplace ostracism is negatively related to group cohesion. The influence of group members’ perception of ostracism on their voice behavior is contingent on overall level of ostracism.

Despite of a growing body of studies on workplace ostracism “the extent to which an individual perceives that he or she is ignored or excluded by others at workplace”, the effects of workplace ostracism on individual’s voice behavior in group settings have received scant attention.

The extant literature mainly focuses on the antecedents and outcomes of envy at the individual level. Workgroups have become ideal units for research on envy given the ubiquitous teamwork in organizations. This study aims to examine whether, how and when envy climate can influence group performance.

The authors analyzed data collected in three waves from a sample of 72 groups with 475 team members in full-service hotels in China.

Envy climate was negatively associated with group performance via intragroup relationship conflict. Furthermore, competitive climate moderated the effect of envy climate on intragroup relationship conflict and the indirect effect of envy climate on group performance through intragroup relationship conflict.

The present research offers organizations valuable insights into how to minimize the climate of envy and competition within a group and relieve the relationship conflict that may damage group performance.

Drawing on a social functional perspective of emotions, this study enriches the envy research by conceptualizing envy climate as a collective perception and clarifying its effect on group performance. The authors extend the understanding of envy climate by showing how a climate of envy embedded in a group influences group performance and also explain when group members may be more likely to act in a destructive way to respond to such a climate.

This study aims to explore how a buyer's perceived buyer-seller (B-S) guanxi facets (i.e. ganqing, renqing and mianzi) and guanxi positions (i.e. zi-ji-ren, shou-ren and sheng-ren) affect the seller's influence effectiveness (SIE) and purchase intention (PI) in social commerce.

This study conducted an online survey in three cities of Taiwan and collected a total of 364 data. The structural equation modeling and cluster analysis were used to test research hypotheses.

The results indicate that (1) each guanxi facet exerts a different and positive impact on SIE, but only one guanxi facet – renqing – helps improve PI, (2) guanxi facets can be used to predict the buyer's perceived guanxi position toward the seller, (3) the effect of guanxi facets on SIE and PI varies across B-S guanxi positions and (4) the SIE positively mediates effects of guanxi facets on the PI.

This study demonstrates the individual effect of each guanxi facet on SIE and PI and affirms the implicit guanxi position features guanxi facets and determines the buyer's perceived SIE and PI as well. To the best of our knowledge, these findings are rarely proposed in previous research and are beneficial for understanding the guanxi mechanism in social commerce.

The purpose of this study is to promote laminar heat transfer from the channel heated through a slab with slits and inclined ribs protruding across.

The novel design of this study is performed through making the slits in the slab (C1–C3: with slits; C4–C6: without slits) and changing the vertical location of this slab (1/4, 1/2 and 3/4 channel height). The thermal fluid characteristics of all cases are analyzed for various Reynolds numbers (500, 1,000, 1,500 and 2,000) by the SIMPLE-C algorithm.

The results display that the ribbed slab effectively improves the heat transfer. The slits can modify the flow field in the vortexes around the inclined ribs and remove more heat from this zone to promote the heat transfer. As compared with C0 (without a slab), C2 (the slab with slits and inclined ribs protruding across located vertically on the 3/4 channel height) raises the averaged Nusselt number up to 27.7% at Re = 2,000. As compared with C4 (without slits), C1 (with slits) gains the maximum increase in the averaged Nusselt number by 5.07% at Re = 1,000.

The constant thermo-physical properties of incompressible fluid and the steady flow are considered in this study.

The numerical results will profit the design of heated passageway using a slab with slits and inclined ribs protruding across to acquire better heat transfer promotion.

This slab with slits and inclined ribs protruding across can be applied to the heat transfer promotion and thus be viewed as a useful cooling mechanism in the thermal engineering.
