Abstract
Purpose
The purpose of this study is to use the individual blade pitch control (IBC), reduce actively both the rotor hub vibratory loads and airframe vibration responses for the lift-offset compound helicopter at a high-speed flight condition.
Design/methodology/approach
The Sikorsky X2 technology demonstrator (X2TD) is used as the lift-offset compound helicopter. The X2TD lift-offset rotor is modelled and its rotor hub vibratory loads at a flight speed of 250 knots are predicted using a rotorcraft comprehensive analysis code, CAMRAD II, and the airframe structural dynamics is represented with a finite element analysis code, MSC.NASTRAN. When the propulsive trim methodology is applied for rotor trim, the best input condition for IBC using multiple harmonic inputs is searched to reduce the rotor vibration, while the rotor aerodynamic performance (the rotor effective lift-to-drag ratio) is improved or maintained at least. Finally, the reduction in airframe vibration responses is investigated when the best input condition for IBC with multiple harmonics is applied to the lift-offset rotor.
Findings
When the IBC with the single harmonic input using the 2/rev actuation frequency, amplitude of 2° and control phase angle of 120° (2P/2°/120°) is considered for X2TD rotor, the rotor vibration is reduced by about 26.37% only and the rotor effective lift-to-drag ratio increases slightly by 0.98%. When X2TD rotor uses the IBC with multiple harmonic inputs (2P/2°/45° + 5P/1°/90°), the rotor hub vibratory loads and airframe vibration responses are reduced by 44.69% and from 0.48 to 79.10%, respectively, while rotor effective lift-to-drag ratio is improved by 0.77%, as compared to the baseline without IBC.
Originality/value
This study is the first study to use the 2/rev actuation for IBC to the four-bladed lift-offset coaxial rotor and to investigate to obtain simultaneously the rotor vibration reduction, rotor performance improvement and airframe vibration reduction, using IBC with multiple harmonic inputs.

Abstract
Purpose
Consumers often communicate with other consumers and perform impulse buying behavior on social commerce websites. Based on stimulus-organism-response framework and dual systems theory, the present study examines the effects of social interactions and self-control on consumers' impulse purchase.
Design/methodology/approach
An online survey consisting of 315 participants on social commerce websites was recruited to empirically examine the proposed research model. Partial Least Squares (PLS) was employed to analyze the research model.
Findings
Our main findings indicate that (1) source credibility, observational learning and review quality are important antecedents of perceived usefulness of online reviews, (2) source credibility, observational learning and perceived usefulness positively affect positive affect, which further results in urge to buy and impulse buying, (3) self-control weakens the effect of positive affect on urge to buy impulsively and also weakens the effect of urge to buy impulsively on impulse buying behavior.
Originality/value
The present study will bring more attention to social interactions in social networks in practice and encourage scholars to pay more attention to the reflective system in online impulse buying.

Abstract
Purpose
The purpose of this paper is to examine the underlying mechanism through which high-performance work system (HPWS) influences employee creativity. In addition, this paper aims to examine contingent factors in the relationship between perceived organisational support and employee creativity.
Design/methodology/approach
The sample of the study included 268 employees and matched supervisors from two pesticide chemical companies in China. Hypotheses were tested with linear regressions.
Findings
The study shows that HPWS enhances perceived organisational support, which in turn promotes employee creativity. Moreover, the results also indicate that devolved management positively moderates the relationship between perceived organisational support and employee creativity.
Research limitations/implications
The unique environment of China may limit the generalisability of the findings. Future studies can extend these findings by conducting studies in other societal contexts.
Practical implications
When trying to inspire employee creativity, organisations need to pay attention to employees’ perception of organisational support. One way of enhancing perceived organisational support is to implement HPWS. In addition, organisations need to encourage devolved management in order to inspire more creative behaviours.
Originality/value
This is the first study that explores the mediating role of perceived organisational support in the HPWS-employee creativity linkage. In addition, the study provides what is believed to be the first test of the moderating role of devolved management.

Abstract
Purpose
This paper aims to shed some new light on the mixed findings of previous empirical studies on the effect of knowledge search breadth (SB) on firms’ 2019 innovation performance (IP).
Design/methodology/approach
The paper adopts a contingent approach that examines the two organizational factors in determining the shape of the SB-IP curve. The empirical study is based on survey data gathered from 414 Chinese firms. In dealing with concerns on simultaneity and reverse causality, perceived time-lag between outcome variable and explanatory variables was introduced.
Findings
This study reveals that knowledge novelty and absorptive capacity are two functions underlying the SB-IP relationship. The results also indicate that innovation orientation and firm age moderate the SB-IP relationship in different ways: the more innovation-oriented the firm, the steeper the inverted U-shaped SB-IP relationship will be, while the older the firm, the flatter the SB-IP relationship will be. Interestingly, there is strong evidence for the shape-flip phenomenon of the SB-IP curve: SB has an inverted U-shaped effect on IP when a firm is young; however, SB has a U-shaped effect when the firm is older than 37 years.
Originality/value
By revealing two underlying functions and two moderators of the association between SB and IP at the firm level, this paper contributes to shed some new light to the mixed results reported by previous empirical studies that have examined the effect of knowledge search on firm innovation.

Abstract
Purpose
Virtual reality (VR), as a new type of media technology, significantly improves the audience experience with product presentation in the marketing communication field. The apartment rental market, particularly in China, has no exception in adopting VR technology in its communication strategy. VR usage has been boosted since the outbreak of COVID-19 and has become a widespread application in the global apartment rental market. Although extant studies have analyzed how real estate companies use VR technology to enhance customer experience, few studies have been made to explore the power of VR in apartment rental advertising, particularly in targeting the youth in China market. To fill this research gap, this study aims to figure out how young consumers perceive VR advertising and characteristics of VR used in apartment rental advertisements, and how VR advertising affects young consumers’ intentions to rent an apartment.
Design/methodology/approach
A cross-sectional survey was conducted in 2021 with 301 Chinese university students aged 18 to 23. All respondents were invited offline and guided to watch one selected rental advertisement with VR technology featuring an apartment of about 50 square meters and then complete a questionnaire.
Findings
VR’s media richness in the apartment rental advertising increases its sense of presence perceived by the survey respondents. Both VR’s media richness and sense of presence positively influence respondents’ attitudes toward the advertised apartment. If respondents evaluate the advertised apartment positively, they are more willing to rent the advertised apartment.
Research limitations/implications
The sample size is not large enough to represent all Generation Z consumers in China. The use of the nonprobability sampling method also limits the generalizability of the study results.
Practical implications
To counter the challenges created by COVID-19, apartment rental service providers and apartment owners/landlords are suggested to enhance the application of VR technology to the apartment rental advertisements to grow young consumers’ interest in the advertised apartments and even their renting intention.
Originality/value
To the best of the authors’ knowledge, this is the first quantitative study to assess young consumers’ responses to VR apartment rental advertising in China.

Abstract
Purpose
This study aims to examine how virtual influencers (VIs) affect purchase intentions in tourism and hospitality e-commerce live streaming (THCLS) by focusing on the roles of VIs’ source credibility, trust in products, trust in VIs, emotional engagement, parasocial relationships and influencer–product congruence.
Design/methodology/approach
Survey data from 416 active viewers of VIs in THCLS were analysed using partial least squares structural equation modelling.
Findings
This study highlights the importance of the VIs’ source credibility, which positively affects trust in the product, trust in VIs and emotional engagement. However, source credibility does not have a positive impact on parasocial relationships. Trust in products positively influences trust in VIs. Emotional engagement and trust in VIs significantly influence parasocial relationships, which, positively affects purchase intentions. Influencer–product congruence strengthens the link between parasocial relationships and purchase intentions but does not moderate the relationship between trust in VIs and purchase intentions. No significant gender differences were observed, although minor discrepancies were noted in the effect of trust in products on trust in VIs. The importance–performance map analysis revealed that parasocial relationships are the most important factor influencing purchase intentions, while influencer–product congruence has the highest performance, trust in products is the least important and VIs’ source credibility has the lowest performance.
Practical implications
This study provides actionable insights for marketers leveraging VIs in the THCLS sector, emphasizing strategies to enhance VI credibility, foster parasocial relationships, ensure influencer–product congruence and adopt gender-neutral marketing approaches to effectively influence purchase intentions.
Originality/value
This study offers theoretical and practical insights into the role of VIs in THCLS, illuminating their impact on consumer behaviour and purchase intentions.

Abstract
Purpose
The purpose of this paper is to investigate the diffusion patterns of knowledge in inspiring technological innovations and to enable monitoring development trends of technological innovations based on patent data analysis, thus, to manage knowledge wisely to innovate.
Design/methodology/approach
The notion of knowledge innovation potential (KIP) is proposed to measure the innovativeness of knowledge by the cumulative number of patents originated from its inspiration. KIP calculating formula is regressed in forms of two specific diffusion models by conducting a series of empirical studies with the patent-based indicators involving forward and backward citation numbers to reveal knowledge managing strategies regarding innovative activities.
Findings
Two specific diffusion models for regressing KIP formula are compared by empirical studies with the result indicating the Gompertz model has higher accuracy than the Logistic model to describe the developing curve of technological innovations. Moreover, the analysis of patent-based indicators over diffusion stages also revealed that patents applied at earlier diffusion stages normally has higher forward citation numbers indicating higher innovativeness meanwhile the patents applied at the latter stages usually requiring more knowledge inflows observed by their larger non-patent citation and backward citation amounts.
Originality/value
Although there is a large body of literature concerning knowledge-based technological innovation, there still room for discussing the mechanism of how knowledge diffuses and inspired knowledge. To the best of authors' knowledge, this study is the first attempt to quantitate the innovativeness of knowledge in technological innovation from the knowledge diffusion perspective with findings to support rational knowledge management related to innovation activities.

Abstract
Purpose
The problematic use of social media progressively worsens among a large proportion of users. However, the theory-driven investigation into social media addiction behavior remains far from adequate. Among the countable information system studies on the dark side of social media, the focus lies on users' subjective feelings and perceived value. The technical features of the social media platform have been ignored. Accordingly, this study explores the formation of social media addiction considering the perspectives of users and social media per se on the basis of extended motivational framework and attachment theory.
Design/methodology/approach
This study investigates the formation of social media addiction with particular focus on WeChat. A field survey with 505 subjects of WeChat users was conducted to investigate the research model.
Findings
Results demonstrate that social media addiction is determined by individuals' emotional and functional attachment to the platform. These attachments are in turn influenced by motivational (perceived enjoyment and social interaction) and technical (informational support, system quality and personalization) factors.
Originality/value
First, this study explains the underlying mechanism of how users develop social media addiction. Second, it highlights the importance of users' motivations and emotional dependence at this point. It also focuses on the technical system of the platform that plays a key role in the formation of addictive usage behavior. Third, it extends attachment theory to the context of social media addictive behavior.

Abstract
Quality-Oriented Education (su zhi jiao yu) is a national education reform initiative that presents ongoing opportunities and challenges to schools, local bureaus of education, and the overall educational system in China today. This chapter seeks to gain insight into if and how Quality-Oriented Education, 10 years into its enactment, has taken root in practice. We posit that a reform agenda is best manifested through well-aligned and operable standards for school effectiveness. We introduce the policy-driven definition for school effectiveness and an evaluation framework depicting the intended focus of Quality-Oriented Education. Using an iterative and inductive process for content analysis, we compare the policy-driven framework with the coding results of a 2009 national inventory of actual school evaluation schemes in 91 Chinese school districts. Our review points out that the new mission of Quality-Oriented Education advocates educational equity, curriculum reform, and systemic support for school-based management. However, at the operational level, there are great variations in terms of content domain, focus, and function among school evaluation schemes with notable regional differences. Furthermore, schools are still caught between the existing system that measures school performance by achievement and the intended accountability scheme that calls for enhanced student ability. This chapter adds to the empirical foundation for the development of a new framework that not only captures the spirit of the national educational reform but also is informed of the developmental needs of schools in drastically different geo-economical and social conditions.
