This paper aims to analyze high-quality papers on the research of electronic word-of-mouth (eWOM) for product and service quality improvement from 2009 to 2022, in order to fully understand their historical progress, current situation and future development trend.

This paper adopts the bibliometrics method to analyze the relevant literature, including publishing trend and citation status, regional and discipline area distribution, and influential publications. Secondly, the VOSviewer is used for literature co-citation analysis and keyword co-occurrence analysis to obtain the basic literature and research hotspots in this research field.

Firstly, the study finds that the number of publications basically shows an increasing trend, and those publications are mainly published in tourism journals. In addition, among these papers, China has the largest number of publications, followed by the USA and South Korea. Through co-citation analysis of literature and keyword co-occurrence analysis, 22 foundational papers and six main research topics are obtained in this paper. Finally, this paper elaborates on the development trend of the research topic and future research directions in detail.

This is the first paper that uses bibliometrics to analyze and review relevant researches on eWOM for product and service quality improvement, which is helpful for researchers to quickly understand its development status and trend. This review also provides some future research directions and provides a reference for further research.

The purpose of this paper is to examine the impact of social media sharing on tourists’ willingness to pay more (WPM) at destinations. The moderating effects of tourists’ preferred route in decision-making or obtaining information (i.e. central or peripheral routes) were also examined.

A theoretical model was developed and tested using partial least squares structural equation modeling (PLS-SEM). Moderating effects of central and peripheral routes were tested using PLS multi-group analysis. Data were collected from 478 tourists in Antalya, Turkey, a sea, sun and sand tourist destination.

Findings indicate that importance attached to participant sharing (IPS) and importance attached to non-participant sharing (INPS) are significant antecedents of tourists’ WPM intentions. Moderating effects of tourists’ preferred route in decision-making reveal that the effect of IPS on WPM intention is more influential for those with high central route preferences than those with low central route preferences. While the effects of INPS and IPS on WPM intention is more determinative for those with higher peripheral route preferences.

Although it is known by the practitioners that consumer-generated contents are important, this research suggests and supports that these contents trigger tourists to pay higher prices.

How WPM is motivated by others’ social media sharing was not very clear in the literature. Therefore, this research gap was addressed in part by examining the social media sharing structure in terms of whether others posted on organization-related sites or on personal sites.

标题探索可能性路线在用户生成内容和支付意愿关系中的作用

本研究旨在探讨社交媒体分享对旅游者在目的地的支付意愿（WPM）的影响。还考察了旅游者在决策或获取信息时偏好路线（即中心或外围路线）的调节效应。

本文利用偏最小二乘结构方程模型（PLS-SEM）建立了理论模型并进行了验证, 使用PLS多组分析法检验了中心和外围路线的调节作用。从土耳其安塔利亚的478名游客中收集了数据。安塔利亚是一个拥有海洋、阳光和沙滩的旅游胜地。

结果表明, 游客对参与式分享（IPS）的重视程度和对非参与式分享（INPS）的重视程度是游客支付意愿 (WPM) 的显著前因。旅游者偏好路线在决策中的调节效应表明, IPS对WPM意图的影响, 对中心路线偏好高的游客比中心路线偏好低的游客更为显著。而INPS和IPS对WPM意图的影响对周边路线偏好较高者更具决定性。

尽管用户生成内容的重要性广为从业人员了解, 但本研究表明, 这些内容还能促使游客支付更高的价格。

在现有文献中, 他人的社交媒体分享是如何激励产生WPM的还不是很清楚。因此, 本文通过考察社交媒体分享的结构来填补这一研究空白, 即考察他人的内容是发布在组织相关的网站上还是个人网站上。

El papel de las rutas ELM (modelo de probabilidad de elección) en la relación entre el contenido generado por usuarios y la disposición a pagar

El propósito de esta investigación es examinar el impacto de la compartición en redes sociales con la disposición de los turistas a pagar más (willness pay more: WPM) en los destinos. También se examinaron los efectos moderadores de la ruta preferida de los turistas en la toma de decisiones u obtención de información (es decir, rutas centrales o periféricas).

Se desarrolló y probó un modelo teórico utilizando modelos de ecuaciones estructurales de mínimos cuadrados parciales (PLS-SEM). Los efectos moderadores de las rutas centrales y periféricas se probaron mediante análisis multigrupo de PLS. Se recopilaron datos de 478 turistas en Antalya, Turquía, un destino turístico de mar, sol y arena.

Los resultados indican que la importancia atribuida a la compartición de los participantes (importance participant sharing: IPS) y la importancia atribuida al la compartición de los no participantes (importance no participant saharing: INPS) son antecedentes importantes de las intenciones de los WPM de los turistas. Los efectos moderadores de la ruta preferida de los turistas en la toma de decisiones revelan que el efecto de IPS en la intención de WPM es más influyente para aquellos con altas preferencias de ruta central que aquellos con bajas preferencias de ruta central. Mientras que los efectos de INPS e IPS en la intención de WPM son más determinantes para aquellos con mayores preferencias de ruta periférica.

Aunque los profesionales saben que los contenidos generados por los consumidores son importantes, esta investigación sugiere y respalda que estos contenidos provocan que los turistas paguen precios más altos.

Al no estar clara en la literatura la relación de la WPM con la compartición en redes sociales y existir una brecha de investigación en este aspecto, este trabajo pretende abordar este tema, examinando la estructura de la compartición en redes sociales en términos de si otros publicaron en sitios relacionados con la organización o en sitios personales.

This paper aims to get an in-depth understanding of the fuel spray characteristics to further improve the emission performance of a lean premixed prevaporized (LPP) combustor with staged lean combustion.

In this paper, the fuel spray characteristics in the LPP combustor are experimentally studied by using particle image velocimetry (PIV), and raw data are processed by image-processing technologies for different inlet conditions. The effects of the fuel allocation and pilot atomizer position on fuel spray characteristics are investigated.

Experiment results show that when only the pilot atomizer is operated, the fuel spray characteristics is worsened by increasing fuel flow rate. The fuel spray fields generated by the pilot atomizer are better at the throat than that at the pilot swirler outlet; when the pilot atomizer and primary injector are operated at the same time with the same inlet fuel air ratio, the spray characteristics are improved by increasing the primary fuel flow rate and decreasing the pilot fuel flow rate. Meanwhile, fuel spray fields generated by the pilot atomizer are better at the throat than that at the pilot swirler outlet.

The present results are useful for further development of the LPP combustor.

An LPP combustor with staged lean combustion technology was proposed; to obtain fuel spray characteristics, image-processing program was compiled; the fuel spray characteristics in the LPP combustor were investigated, especially the effects of the fuel allocation and pilot atomizer position.

Mobile health service (MHS) can provide users with convenient health services and information to reduce their medical costs from aging or other health issues. Previous studies confirm the underdevelopment of the Chinese MHS. The purpose of this paper is to analyze the factors that affect the intention to use MHS.

This paper develops a research model that integrates personal health differences with theory of planned behavior (TPB) and protection motivation theory (PMT). This model is empirically tested using data from 494 valid questionnaires. Structural equation modeling is used to test the hypotheses.

Perceived vulnerability to disease, perceived severity of disease, response efficacy and self-efficacy positively affect attitude, thereby exerting a positive influence on the behavioral intention to use MHS. Subjective norms also influence users’ behavioral intention. Personal health status and personal health value have quasi-moderating effects on the relationship between attitude and behavioral intention.

This paper presents an early attempt to conceptualize and validate a research model of MHS acceptance by integrating TPB and PMT in a complementary manner. The integrated model provides a holistic view of people’s intention to use MHS by considering health threat beliefs, individual role (i.e. attitude and self-efficacy) and social influences (i.e. subjective norms). Furthermore, this research highlights the role of two individual health characteristics (i.e. personal health status and personal health value) in MHS adoption. These new findings are beneficial toward an in-depth understanding of technology adoption in the MHS context.

The image of the construction industry in China, as in many other countries, is tarnished by its poor safety record. With the rapid development of subway systems in Chinese urban areas, construction workers are being exposed to new risks which are poorly understood and managed. Subway construction projects are large scale and scattered over many construction sites, and involve numerous stakeholders and sophisticated technologies in challenging underground environments. Accident rates are high and have significant economic and social consequences for the firms and people involved. Addressing the gap in research about the safety risk in these projects, the purpose of this paper is to advance understanding of the factors influencing the safety of Chinese subway construction projects with the overall objective of reducing accident rates.

A survey was conducted with 399 subway construction professionals across five stakeholder groups. Follow-up interviews were also conducted with five experienced experts in safety management on subway projects to validate the results.

It was found that the eight most critical factors perceived by stakeholders to influence safety risks on Chinese subway projects are: project management team; contractor-related factors; site underground environment; safety protection during the use of machines; safety management investment; site construction monitoring and measurement; hazard identification and communication; and use of machines in all stages. This indicates that in allocating limited project resources to improve the safety of subway projects, managers should focus on: developing safety knowledge and positive attitudes in leadership teams; formulating effective risk management systems to identify, assess, mitigate, measure and monitor safety risks on site; improving communications with stakeholders about these risks and effectively managing plant, equipment and machinery.

This research contributes a new multi-stakeholder perspective to the lack of safety research in Chinese subway construction projects. The research findings provide important new insights for policymakers and managers in improving safety outcomes on these major projects, producing potentially significant social and economic benefits for society and the construction industry.

The investigations provide a basis for the optimization of the alloy 6061-T6 friction stir welding (FSW) process to improve the mechanical properties of welded joints.

The local deformation of the FSW joint in tension and fatigue test were experimentally investigated by digital image correlation (DIC) technique.

The local stress-strain behaviors of the sub-regions show that the plastic strain always concentrated at the heat affected zone (HAZ) on the advancing side both in tension and high cycle fatigue and eventually leads to the final fracture. The evolution of the plastic strain at very low stress is extremely slow and accounts for most of the total fatigue life. However, the local deformation exhibits a sudden increase just before the fatigue failure.

Based on the experimental data, the result indicates that the HAZ is the weakest zone across the weld and the strain localization in high cycle fatigue is very harmful and unpredictable for the FSW joints.

The purpose of this paper is to determine (1) the relationship between microstructure and fatigue cracking behavior and (2) effect of rolling on the process of crack initiation and propagation in FeCrAl alloys.

The qualitative and quantitative fracture studies were performed using scanning electron microscopy and the non-contact optical measurement system (IFMG5).

The results show that the formation of facets, rough facets and parallel stripes in the crack initiation and early crack propagation zones are closely related to the sensitivity of crack behavior to the microstructure of the material. Besides, the rolling process has a significant influence on the small crack initiation and propagation behavior. Quantitative analysis demonstrates that the size of the stress intensity factor and plastic zone size in the rough zone is associated with the rolling process.

The findings of this study have the potential to enhance the understanding of the microstructural crack formation mechanisms in FeCrAl alloys and shed light on the impact of rolling on the long-term and ultra-long fatigue behavior of these alloys. This new knowledge is vital for improving manufacturing processes and ensuring the safety and reliability of FeCrAl alloys used in nuclear industry applications.

The substantial cost of employee cyberloafing to organizations calls for research into exploring the factors that influence such behavior. Drawing upon social cognitive theory, the authors develop a theoretical model that unpacks when and why leader forgiveness induces employee cyberloafing. Specifically, the authors identify moral disengagement as a linking mechanism and employee empathic concern as a key boundary condition in the association between leader forgiveness and employee cyberloafing behaviors.

The authors conducted multilevel analyses to examine the authors' hypotheses by utilizing a sample of 71 supervisors and 306 direct reports.

Results showed that leader forgiveness encouraged employee cyberloafing via moral disengagement among employees with low empathic concern, whereas the indirect effect was not present among those with high empathic concern.

The authors contribute to the literature on cyberloafing and leader forgiveness. First, this study extends the cyberloafing research by considering leader forgiveness as an enabler, challenging the dominant notion that positive leader behaviors (e.g. leader mindfulness) constrain employee cyberloafing while negative leader behaviors (e.g. abusive supervision) elicit it. Second, although past studies have predominantly concentrated on the positive outcomes of forgiveness, the current research contributes to the balanced and comprehensive understanding of leader forgiveness by linking leader forgiveness with employee cyberloafing.

Scholars have examined the possible relationship between information technology (IT) and organizational agility. Although the general-level effect of IT is undisputed, empirical research on how different types of IT contribute to various aspects of organizational agility remains scarce. Therefore, this study aims to propose an integrated framework of internal capability and external environment to address this research gap.

This study investigates the potential mediating effects of absorptive capacity and the moderating effects of information intensity in the IT‒agility relationship. With a dataset comprising 165 organizations in China, this work provides empirical evidence that the effects of absorptive capacity and information intensity are multifaceted and nuanced, thereby revealing the latent mechanisms of IT competency and organizational agility.

Absorptive capacity partially mediates the effects of IT knowledge and IT operations on market capitalizing agility and fully mediates their effects on operational adjustment agility. However, no direct or indirect effects of IT objects are found on both types of organizational agility. Information intensity also positively moderates the effects of IT operations and IT objects on absorptive capacity. However, no significant moderation is found with regard to IT operations.

This study provides novel insights by demonstrating clearly the different mediating roles of absorptive capacity in the relationship among various types of IT competency and diverse aspects of organizational agility. This work also underscores the moderating role of information intensity in shaping absorptive capacity through IT competency.

The purpose of this study is to simulate the temperature distribution during an electron beam freeform fabrication (EBF³) process based on a fully threaded tree (FTT) technique in various scales and to analyze the temperature variation with time in different regions of the part.

This study presented a revised model for the temperature simulation in the EBF³ process. The FTT technique was then adopted as an adaptive grid strategy in the simulation. Based on the simulation results, an analysis regarding the temperature distribution of a circular deposit and substrate was performed.

The FTT technique was successfully adopted in the simulation of the temperature field during the EBF³ process. The temperature bands and oscillating temperature curves appeared in the deposit and substrate.

The FTT technique was introduced into the numerical simulation of an additive manufacturing process. The efficiency of the process was improved, and the FTT technique was convenient for the 3D simulations and multi-pass deposits.
