The purpose of this study is to develop a 3D wheel-rail adhesion model under wet condition, which considers the generated surface roughness topography and the traditional braking procedure for high-speed trains.

Wheel-rail adhesion has an important effect on the braking ability of railway vehicle. Based on the deterministic mixed lubrication approach, the model was solved to get the adhesion characteristics of the train during braking. The elastic deformation was calculated with the discrete convolution and fast Fourier transform method. The simulation results of adhesion coefficient were compared with the experimental values. The wheel-rail adhesion characteristics of train braking at several different initial speeds were investigated. The effects of the time-step length and roughness orientation on the contact load ratio were also discussed.

The results show that the adhesion coefficient of the numerical model is in good agreement with the experimental results. At the instant of braking, the adhesion coefficient drops to a lower adhesion level, the value of adhesion coefficient is lower than 0.06, especially at a higher speed (200, 300 and 400 km/h).

It can provide a better understanding of the low adhesion phenomenon of train braking under wet condition.

The purpose of this paper is to explore and examine the relative impact of product and channel attributes on luxury product shopping in the multi-channel environment.

A D-optimal discrete choice conjoint design was used. The data were analysed using a multinomial logit model and desirability indices.

Findings indicate that low price was the most important factor that influenced young consumers' preferences. After price, young luxury consumers placed a greater importance on channel attributes such as human-assisted service and virtual fitting rooms.

The sample consisted of young consumers in their 20s and 30s, who utilise both online and offline channels. Hence, the income level was relatively low. Also, the results cannot be generalised to all luxury consumers.

Providing preferable channel attributes is more crucial to young luxury fashion shoppers than focusing on improving product attributes, with the exception of price.

The paper proposes the optimal combination of key product and channel attributes that is most preferable to young luxury fashion consumers in the multi-channel environment.

For the past years, the population of firms in China has increased fast. However, the financial research has always fallen behind the financial practice. Also, the Western financial theory may not be completely consistent with China’s context. In addition, appearing internet technology with big data and its applications to business bring some challenges not only to financial practice but also to the financial literature. Thus, the purpose of this paper is to review historical development of research in corporate finance, discuss the current issues and propose 16 key research topics in China context.

This paper surveys Western classical literature and some important literature by Chinese scholars in the field of corporate finance. On this basis, the authors point out the shortcomings of existing research and opportunities for future research.

The authors propose 16 key research topics in the near future considering the current reforms on economic development strategy, financial and taxation system and SOE’s property right under the institutional background in China.

This paper makes a contribution to corporate finance research by exploring frontier topics for future research according to the China context and the global trend. These topics represent the demand from enterprises in China and are challenges for the academic world. It is of practical significance and great theoretical value to implement these studies. It will help the management to solve their financial problems and provide a fundamental basis for constructing the financial management theory with Chinese characteristics.

This study seeks to address three research questions: how technology capability impact business performance? Does the linkage between technology capability and business performance depend on specific contexts? Why do some high‐tech firms of strong technological capability fail?

The paper draws on various theoretical perspectives to develop hypotheses that propose a direct relationship between technological capability and business performance (both new product development and overall business performance), the mediating role of customer value, the possible moderating effects of business environment and other important contingent factors such as learning orientation. A conceptual framework is devised and tested that examines these relationships in general and in various contexts, which is believed more important and useful for firms to manage their technological capability more effectively.

Findings from high‐tech firms in China confirm the validity of the framework and afford various insights on the role of various contingent factors in the proposed relationships.

The paper provides a framework that examines companies' technological capability relationships.

To find a successful human action recognition system (HAR) for the unmanned environments.

This paper describes the key technology of an efficient HAR system. In this paper, the advancements for three key steps of the HAR system are presented to improve the accuracy of the existing HAR systems. The key steps are feature extraction, feature descriptor and action classification, which are implemented and analyzed. The usage of the implemented HAR system in the self-driving car is summarized. Finally, the results of the HAR system and other existing action recognition systems are compared.

This paper exhibits the proposed modification and improvements in the HAR system, namely the skeleton-based spatiotemporal interest points (STIP) feature and the improved discriminative sparse descriptor for the identified feature and the linear action classification.

The experiments are carried out on captured benchmark data sets and need to be analyzed in a real-time environment.

The middleware support between the proposed HAR system and the self-driven car system provides several other challenging opportunities in research.

The authors’ work provides the way to go a step ahead in machine vision especially in self-driving cars.

The method for extracting the new feature and constructing an improved discriminative sparse feature descriptor has been introduced.

The purpose of this study is to examine the impact of chief executive officer (CEO) hometown identity on company audit fees in the Chinese setting.

This study uses data from Chinese public companies in the Shanghai Stock Exchange and the Shenzhen Stock Exchange for the period 2008–2019. This study investigates the impact path of CEO hometown identity on company audit fees and further examines the moderating role of internal and external governance level.

This study finds that CEO hometown identity is significantly and negatively related to company audit fees. In addition, CEO hometown identity can reduce audit fees by alleviating agency risk and litigation risk. Moreover, the negative effect of CEO hometown identity on audit fees is more pronounced in companies with a higher percentage of institutional investors shareholding and more analysts tracking quantity.

This study may provide new references for executives’ selection, auditors’ optimization decisions and regulators’ information disclosure system.

This study contributes to the literature by exploring the effect of CEO hometown identity on audit fees in the context of China.

This study aims to explore the gap between information needs and services for autism in China.

The gap is revealed by investigating the status quo of autism information needs and services. The authors extracted categories and subcategories of information needs through content analysis of academic documents and then supplemented the subcategories through text mining of an online forum. Meanwhile, categories and subcategories of information services were extracted through content analysis of autism websites. Finally, the authors matched the two to explore the gap and designed a quantitative index to measure it.

A total of eight and ten categories of information needs and services are extracted, respectively. In total, six categories of information needs can be partly matched, but nearly half of the subcategories failed. Huge gaps in economic support, sociality and policy mechanisms categories are observed through the quantitative index and medium gaps in social resource services and employment categories while almost no gaps in psychological/emotional counseling, rehabilitation skills training and professional knowledge/information categories.

This study takes a deep insight into the gap between autism information needs and services in China, providing evidences and suggestions for information providers to improve their services. Academic documents and online forum data are adopted to avoid the impact of stigmatization, which provides a multi-source data analysis approach for the information needs of special groups.

From the perspective of top management heterogeneity, this paper aims to study the impact of the psychological traits of executive pay bandwagon on earnings management in the listed companies of China.

This paper applies the ratio of executive pay to the median pay level of executives in firms of similar size and industry, namely, the comparing coefficient, as an alternative variable of executive pay bandwagon, and earnings management as the behavior choice of executive pay bandwagon, to examine whether executives in the listed companies of China have comparing mentality, and whether the result is influenced by executive heterogeneity by using the multiple linear regression models.

The lower the executives’ compensation is than the median pay level of executives in firms of similar size and industry, the stronger the incentive the executives have to compare with others whose pay is higher, increasing the extent of earnings management in the future, and executives tend to use real activities manipulation rather than accrual-based earnings management to increase their performance-based compensation. As pay bandwagon is a kind of executives’ individual psychological reaction, in a large extent, its behavioral performance is likely to be affected by executive heterogeneity. Specifically, when the proportion of male executives, young executives or low educated executives is relatively high, or executives are located in remote cities, there will breed more earnings management behaviors induced by pay bandwagon. Further study shows that pay bandwagon is positively correlated with rigging compensation based on real earnings management and pay bandwagon also has significantly negative effects on the firms’ future value creation.

Pay bandwagon is an important inducement of executives’ earnings management, with implication that for executives with different characteristics, one should pay attention to the subjective psychological perception and expectation of their pay in the future studies related to executives’ compensation incentives.

This study introduces the research within sociology, psychology and experimental economics, and considers the executives’ subjective perception of their pay, to explore the internal mechanism that executives affect firm performance via a specific earnings management method and to implement self-interested behavior due to pay bandwagon. And this is the first study to select several typical executive individual characteristics to investigate the influence of executive heterogeneity on pay bandwagon and its economic consequences.

The 2008 global financial crisis stimulated the research interest in stock price crash risk. However, the determinants of stock price crash risk remain unclear, especially in transitional economies. The purpose of this paper is to investigate the association between corporate social responsibility (CSR) and stock price crash risk, as well as the moderating effects under different contexts.

Using firm-level data of listed firms in China from 2010 to 2019, this paper estimates with correlation analysis and multiple regression analysis.

This paper’s empirical results show that the constraint of CSR on bad news hoarding behavior can reduce stock price crash risk. Further research shows that internal CSR has a significant effect on crash risks, while external CSR has not. Additionally, CSR has a relatively weak impact on crash risk in state-owned enterprises, enterprises with higher internal control quality and enterprises with better regional financial development.

This paper contributes to the stock price crash risks literature by examining the CSR-stock price crash risk linkage in a Chinese context, revealing collective explanations under different contexts with important implications for the application of CSR in business practice.

This paper aims to elucidate how humorous prompts affect tourists’ heritage responsible behaviors (THRBs).

Three scenario-based experiments were conducted through Credamo (an online survey platform). Studies 1 and 2 used a single-factor (language style: humorous vs serious) between-subject design to test the direct and indirect effects of humorous prompts. Study 3 used a 2 (environmental quality: high vs low) × 2 (language style: humorous vs serious) between-subject design to further reveal the boundary condition (environmental quality) of the humor effect.

The results revealed that humorous (vs serious) prompts better persuade tourists to engage in heritage responsible behaviors (HRBs). Content liking mediates the relationship between humorous prompts and THRBs. Moreover, environmental quality significantly moderates the effect of humorous prompts on THRBs, whereby the persuasive effect of humorous prompts is greater in high environmental quality conditions than in low environmental quality conditions.

Destination management organizations can use humor to reduce tourists’ reactance against prompts for behavioral persuasion. Moreover, it is also important to adapt humorous prompts to changes in environmental quality in a timely manner.

Based on psychological reactance theory, the research confirmed the dominant effect of humorous prompts by using content liking as a mediating variable, providing a new research perspective for research on the regulation of THRBs. Moreover, the authors clarified a boundary condition for the persuasiveness of humorous prompts, which helps reinforce the comprehension of humor persuasion.

本研究旨在厘清幽默提示语如何影响游客遗产责任行为的差异效应与过程机制。

本研究利用见数平台开展了三个情景实验。实验1与实验2采用单因素（语言风格：幽默 vs. 严肃）组间实验设计, 验证了幽默提示语对遗产责任行为的直接与间接效应。实验3采用2（语言风格：幽默 vs. 严肃）×2（环境质量：高 vs. 低）组间实验设计进一步揭示环境质量对幽默提示语效果的调节效应。

相较于严肃提示语, 幽默提示语可更好地说服游客产生遗产责任行为。内容喜爱在幽默提示语与遗产责任行为过程中发挥完全中介作用。此外, 环境质量调节了幽默提示语对遗产责任行为的影响, 即幽默提示语（较严肃提示语）仅在环境质量较高的遗产地中具备优势。

遗产地管理组织可使用幽默来降低游客对提示语的心理逆反程度, 从而达到行为说服的目的。与此同时, 管理者也要根据目的地环境质量及时调整幽默提示语的使用策略。

基于心理逆反理论, 本研究以内容喜爱为中介变量, 证实了幽默提示语的优势说服作用, 为游客遗产责任行为管理的相关研究提供了一个新的理论视角。同时, 本研究厘清了幽默提示语在遗产旅游地中的应用边界, 并强化了对幽默说服的理解。

Esta investigación pretende aclarar cómo afecta el humor al efecto persuasivo de la señalización sobre el comportamiento responsable de los turistas respecto al patrimonio.

Se realizaron tres experimentos basados en escenarios a través de Credamo (una plataforma de encuestas en línea). En los estudios 1 y 2 se utilizó un diseño entre sujetos de un solo factor (estilo de lenguaje: humorístico frente a serio) para comprobar los efectos directos e indirectos de los señalización humorísticos. El estudio 3 utilizó un diseño entre sujetos de 2 (calidad del entorno: alta frente a baja) × 2 (estilo lingüístico: humorístico frente a serio) para revelar con más detalle la condición límite (calidad del entorno) del efecto del humor.

Los resultados revelaron que las señalización humorísticas (frente a las serias) persuaden mejor a los turistas a participar en las HRB. El gusto por el contenido influye en la relación entre los señalización humorísticos y las HRB. Además, la calidad del entorno modera de forma significativa el efecto de los señalización humorísticos sobre los THRB, de modo que el efecto persuasivo de los señalización humorísticos es mayor en condiciones de alta calidad del entorno que en condiciones de baja calidad del entorno.

Las organizaciones de gestión de destinos pueden utilizar el humor para reducir la reacción de los turistas ante las señalización a la persuasión conductual. Además, también es importante adaptar oportunamente las señalización humorísticas a los cambios en la calidad del entorno.

Basándonos en la teoría de la reactancia psicológica, nuestra investigación confirmó el efecto dominante de las señalización humorísticas empleando el gusto por el contenido como variable mediadora, proporcionando una nueva perspectiva para la investigación sobre la regulación de las THRB. Además, aclaramos una condición límite para la persuasión de los señalización humorísticos, lo que ayuda a reforzar la comprensión de la persuasión humorística.
