Abstract
Purpose
The purpose of this paper is to study the stability analysis and optical solitary wave solutions of a (2 + 1)-dimensional nonlinear Schrödinger equation, which are derived from a multicomponent plasma with nonextensive distribution.
Design Methodology Approach
Based on the ansatz and sub-equation theories, the authors use a direct method to find stability analysis and optical solitary wave solutions of the (2 + 1)-dimensional equation.
Findings
By considering the ansatz method, the authors successfully construct the bright and dark soliton solutions of the equation. The sub-equation method is also extended to find its complexitons solutions. Moreover, the explicit power series solution is also derived with its convergence analysis. Finally, the influences of each parameter on these solutions are discussed via graphical analysis.
Originality Value
The dynamics of these solutions are analyzed to enrich the diversity of the dynamics of high-dimensional nonlinear Schrödinger equation type nonlinear wave fields.

Abstract
A research stream known as prospect theory describes how decision biases lead to results that differ from those predicted by classical utility theory (Kahneman and Tversky, 1979). Prospect theory hypothesizes that individuals will experience potential losses more intensely than potential gains, and will be more risk‐seeking in loss situations, while more risk‐avoiding in gain situations. This study includes 948 participants from the PRC and 318 students from the USA. All of our attempts to replicate these findings in the Peoples’ Republic of China have revealed a different pattern. Chinese subjects consistently demonstrated risk‐seeking preferences, both in gain and loss situations.

Abstract
Purpose
The purpose of this paper is to apply analysis of public discourses on Ze Xiao to explore and interpret the power relationships shaping inequality in admission to public junior high schools in urban China.
Design/methodology/approach
This study first introduces the rise of Ze Xiao as an educational phenomenon in China. It then elucidates power relationships in public school admission by analyzing continuities and changes in stakeholders’ interaction in public school admission. It concludes by discussing educational reform for equal public school admission in urban China. Data were collected from written and spoken texts about public school admission, including newspaper articles from the 1980s to the 2000s, policy documents and interviews with relevant stakeholders.
Findings
Findings demonstrate that multi-layered power relationships caused diverse inequalities in admission to public secondary education in urban China. These are represented by political and institutional privileges and an imbalance in education development during the social transition from a profit-driven approach in the 1990s to a balance-centered one after 2000. Arguably, there is a necessity to further promote a systematic reform to terminate the privileges and imbalance for an equal and balanced public secondary education in urban China post-2015.
Originality/value
This study attempts to make a contribution toward reconstructing the meaning of inequality in admission to public junior high schools in urban areas by revealing the power relationships among stakeholders constituted through their interactions in public education during the different stages of socio-economic development in urban China.

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
This paper aims to report on the China‐North America Library Conference held in Beijing, China. The conference theme is Sharing Digital Resources: Challenges and Opportunities. Six sub‐themes are also intertwined with the conference theme: Resource sharing policies and perspectives; Digital infrastructure and repository technology; Research data sharing; Sharing digital preservation methods; and Shared digital access, retrieval and use.
Design/methodology/approach
The paper summarizes several important presentations at the conference.
Findings
The shared projects in this report include: National Cultural Information Resource Sharing Project; Multicultural Canada Project; Data Conservancy; National Library Digital Exchange Services; and Digital Museum Platform.
Originality/value
This is an original conference report which would help those who are interested in sharing digital resources on a global scale to understand the challenges, issues, and opportunities on that aspect.

Abstract
Purpose
The purpose of this paper is to document earnings management of Chinese firms.
Design/methodology/approach
The paper takes advantage of the introduction of stringent delisting requirements around 2000 that non-cross-listed firms with consecutive earnings losses for more than two years would be delisted from the mainland Chinese exchanges. The paper examines whether listed firms in Chinese market manage earnings to avoid listings. The paper also examines whether mainland Chinese firms cross-listed in Hong Kong exchanges manage earnings the same way. The measure for earnings management is derived from a kernel density estimate for the return on equity distribution, following Bollen and Pool (2009).
Findings
The paper finds that the new delisting threats induce rampant earnings management on mainland markets, and cross-listing in Hong Kong has a curbing effect on earnings management. The paper also finds that prices became less value relevant after the implementation of delisting regulations, and investors rationally discounted the reliability of earnings announcements in China. Such market responses were absent for cross-listed firms in Hong Kong.
Originality/value
There is little conclusive evidence about whether cross-listing in a non-US market has a curbing effect on earnings management. The paper contributes to this literature by using this unique exogenous policy change in China and following a difference-in-difference approach in identifying the potential curbing effect. The particular measure adapted from Bollen and Pool (2009) utilizes information of the whole distribution of return on equity, thus extends earlier crude comparison of nearest two bars around zero and partially deals with the potential endogeneity problem.

Abstract
China represents around 20% of the world's population, and her economy is still performing well under economic crisis. Historical events have shaped different parts of China with different economic developments and cultural encounters. The most prominent difference is between Hong Kong and the Mainland. This chapter would like to examine the development and issues of fashion retailing in China. For better understanding, this chapter starts with a brief discussion on apparel industry development and fashion culture in Hong Kong and the Mainland, follows by historical development and then presents systems of fashion retailing in both Hong Kong and the Mainland. Desktop research and exploratory research techniques were employed. Stores of international fashion luxury brands in Hong Kong, Shanghai and Beijing were visited. Comparison of branding issues, particularly for luxury market in Hong Kong and the Mainland are discussed, so are future directions of fashion retailing in these places.
