Abstract

Purpose

The purpose of this paper is to propose a DC-port voltage balance strategy realizing it by logic combination modulation (LCM). This voltage balance strategy is brief and high efficient, which can be used in many power electronic devices adopting the cascaded H-bridge rectifier (CHBR) such as power electronic transformer (PET).

Design/methodology/approach

The CHBR is typically as a core component in the power electronic devices to implement the voltage or current conversion. The modulation method presented here is aiming to solve the voltage imbalance problem occurred in the CHBR with more stable work station and higher reliability in ordinary operating conditions. In particular, by changing the switch states smoothly and quickly, the DC-port voltage can be controlled as the ideal value even one of the modules in CHBR is facing the load-removed problem.

Findings

By using the voltage balance strategy of LCM, the problem of voltage imbalance occurring in three-phase cascaded rectifiers has been solved properly. With the lower modulation depth, the efficiency of the strategy is shown to be better and stronger. The strategy can work reliably and quickly no matter facing the problem as load-removed change or the ordinary operating conditions.

Research limitations/implications

The limitation of the proposed DC-port voltage balance strategy is calculated and proved, in a three-module CHBR, the LCM could balance the DC-port voltage while one module facing the load-removed situation under 0.83 modulation depth.

Originality/value

This paper provides a useful and particular voltage balance strategy which can be used in the topology of three-phase cascaded rectifier. The value of the strategy is that a brief and reliable voltage balance method in the power electronic devices can be achieved. What is more, facing the problem, such as load-removed, in outport, the strategy can response quickly with no switch jump and switch frequency rising.

Abstract

Purpose

The study examines the potential moderating effects of repeating purchase cues and product knowledge on the relationship between the varying consistency of the review set and causal attribution. This study also investigates how causal attribution correlates with the perceived misleadingness of the review set.

Design/methodology/approach

A scenario-based experiment was conducted with 170 participants to explore the relationship between the consistency of the review set and causal attribution and how repeating purchase cues and product knowledge moderates this relationship.

Findings

Findings suggest that inconsistent review sets lead to more product (vs reviewer) attribution than consistent review sets. The repeating purchase cues mitigate the negative relationship between the consistency of the review set and product attribution, whereas product knowledge mitigates the positive relationship between the consistency of the review set and reviewer attribution. Furthermore, the results indicate that high product attribution and low reviewer attribution are associated with low perceived misleadingness.

Originality/value

This study is novel because it examines the moderating effects of repeating purchase cues and product knowledge on the relationship between the consistency of the review set and causal attribution. It adds to the literature by shedding light on the causal attribution process underlying the formation of perceived misleadingness of online reviews. The findings of this study provide valuable insights for managers on how to enhance the positive effects of consistent review sets and mitigate the negative effects of inconsistent review sets.

Abstract

Purpose

Social media commerce provides a convenient way for users to share information and interact with each other. Few studies, however, have examined the effect of marketing messages and consumer engagement behaviors on the economic performance of marketing. This study, therefore, explored the economic performance of social media in terms of marketing messages and consumer engagement.

Design/methodology/approach

Using ordinary least squares regression and data collected from Weibo and Maoyan, this study analyzed the effects among marketing messages, consumer engagement and movie ticket sales.

Findings

The results indicated that marketing messages on Weibo had a positive effect on box office revenues, while consumer engagement behavior (whether personal or interactive) did not affect box office revenues. The results suggested that marketing messages on social media have more salient effects for predicting economic performance than consumer engagement behaviors.

Originality/value

This study underscores the importance of social media in consumer purchasing behavior. The findings also extend the literature related to commerce and product message design on social media platforms.

Abstract

Purpose

Teacher well-being has been a concern, but there has been a lack of research on how teacher leadership can contribute to teacher well-being in a high-accountability context and a hierarchical education system such as that of China, particularly through the meditating roles of trust in the leader and teacher efficacy. Therefore, the purpose of this study was to understand the relationship between teacher leadership and teacher well-being while exploring the mediating roles of trust in leaders and teacher efficacy in this relationship.

Design/methodology/approach

Using structural equation modeling (SEM) and bootstrap methods with valid answers from 1,144 teachers in 25 primary schools in 1 Chinese city, this study mainly answered three questions: Is there a significant relationship between teacher leadership and teacher well-being? Is there a significant mediating effect of trust in leaders on the relationship between teacher leadership and teacher well-being? Is there a significant mediating effect of teacher efficacy on the relationship between teacher leadership and teacher well-being?

Findings

This study reported a positive relationship between teacher leadership and teacher well-being. This study also found positive mediating roles for trust in leaders and teacher efficacy in the relationship between teacher leadership and teacher well-being in a high-accountability and hierarchical system like that of China.

Originality/value

This study provides an understanding of the transferability of teacher leadership theories across cultures and has practical significance for educational practice in high-accountability and hierarchical education contexts similar to that of China.

Abstract

Purpose

Drawing upon the social identity approach, this research examines whether and how leader–subordinate congruence at high levels of proactive personality facilitates subordinate creativity.

Design/methodology/approach

Two different data sets (Study 1: N = 205; Study 2: N = 222) were collected from leader–subordinate dyads in China to provide stronger empirical evidence regarding our hypotheses. Polynomial regression and response surface analyses were used to test our predictions.

Findings

Subordinate creativity in the scenario in which the leader and subordinate shared a highly proactive personality (i.e. high–high congruence) was higher than that in the incongruence or low–low congruence scenario. The subordinate's identification with the leader mediated the above relationships such that the indirect relationship between leader–subordinate proactive personality and subordinate creativity via identification with the leader was maximized in the high–high congruence scenario.

Practical implications

The findings suggest that organizations should consider selecting both highly proactive leaders and highly proactive subordinates to facilitate the subordinates' identification and subsequent creativity.

Originality/value

This research highlights the crucial role of leader–subordinate congruence in strong proactive personality for the promotion of creativity and reveals that identification with the leader accounts for the above relationship.

Abstract

Purpose

Consumers’ motivations for purchasing counterfeit branded luxuries are a topic of heated discussion amongst academics and practitioners. Drawing on self-discrepancy theory, the purpose of this paper is to examine the effects of actual-ideal self-discrepancy on consumers’ attitudes towards counterfeit branded luxuries. It investigates how self-monitoring and perceived social risk moderate this effect. Furthermore, it explores cross-cultural differences in the impact of actual-ideal self-discrepancy.

Design/methodology/approach

A pilot study provides preliminary evidence that highlights the importance of actual-ideal self-discrepancy in counterfeit consumption. Based upon a large-scale survey across Hong Kong, the USA and Australia, the principal study explores the moderating effect of self-monitoring and perceived social risk as well as cross-cultural differences.

Findings

The results indicate that self-discrepancy increases consumers’ tendency to engage in symbolic consumption, and that consumption of counterfeit branded luxuries can serve the social function of self-expression to reduce the discomfort induced by self-discrepancy. Self-monitoring and perceived social risk have significant moderating effects, with the former strengthening and the latter attenuating this effect. Moreover, the effect of self-discrepancy is more pronounced amongst individualistic consumers than collectivistic consumers.

Originality/value

This is the first study to highlight the significance of self-discrepancy in the consumption of counterfeit branded luxuries. It examines the important moderating effects of self-monitoring and perceived social risk. Consumers from collectivistic and individualistic cultures define their self-concept differently, thus the findings provide meaningful cross-cultural information on the impact of self-discrepancy in counterfeit consumption.

Abstract

This study explains the international opportunity development of SMEs from emerging economies during institutional transition. This research enriches our understanding of how these firms adopt different approaches to developing international opportunities when they confront the turbulent institutional environment. We develop a phase-based framework for the evolution of transitional institution for SMEs’ internationalization and the SMEs’ internationalization process in that framework. By providing an empirical case study of a privately owned SME from China, the main finding is that SMEs from emerging economies become more entrepreneurial and proactive in developing the international opportunity during the institutional transition.

Abstract

Purpose

The purpose of this paper is to describe a simulation and experimental research concerning the effect of recess depth on the lubrication performance of a hydrostatic thrust bearing by constant rate flow.

Design/methodology/approach

The computational fluid dynamics and finite volume method have been used to compute the lubrication characteristics of an annular recess hydrostatic thrust bearing with different recess depths. The performances are oil recess pressure, oil recess temperature and oil film velocity. The recess depth has been optimized. A test rig is established for testing the pressure field of the structure of hydrostatic thrust bearing after recess depth optimization, and experimental results show that experimental data are basically identical with the simulation results, which demonstrates the validity of the proposed numerical simulation method.

Findings

The results demonstrate that the oil film temperature decreases and the oil film pressure first increases and then decreases with an increase in the recess depth, but oil film velocity is constant. To sum up comprehensive lubrication performance, the recess depth of 3.5 mm is its optimal value for the annular recess hydrostatic thrust bearing.

Originality/value

The computed results indicate that to get an improved performance from a constant flow hydrostatic thrust bearing, a proper selection of the recess depth is essential.

Abstract

Purpose

Based on the random aggregate model of recycled aggregate concrete (RAC), this paper aims to focus on the effect of loading rate on the failure pattern and the macroscopic mechanical properties.

Design/methodology/approach

RAC is regarded as a five-phase inhomogeneous composite material at the mesoscopic level. The number and position of the aggregates are modeled by the Walraven formula and Monte–Carlo stochastic method, respectively. The RAC specimen is divided by the finite-element mesh to establish the dynamic base force element model. In this model, the element mechanical parameters of each material phase satisfy Weibull distribution. To simulate and analyze the dynamic mechanical behavior of RAC under axial tension, flexural tension and shear tension, the dynamic tensile modes of the double-notched specimens, the simply supported beam and the L specimens are modeled, respectively. In addition, the different concrete samples are numerically investigated under different loading rates.

Findings

The failure strength and failure pattern of RAC have strong rate-dependent characteristics because of the inhomogeneity and the inertial effect of the material.

Originality/value

The dynamic base force element method has been successfully applied to the study of recycled concrete.
