The personal traits of expatriates influence their work performance in a subsidiary. Nevertheless, organizations tend to hire candidates who are suitable from the technological dimension but ignore personal and family factors. Expatriates might not be familiar with a foreign place, and most organizations do not provide the so-called cultural adjustment training. The selected expatriates often accept the job without knowing the future prospects of their career, which can result in individual and family turmoil initially. Moreover, the unknown future career prospects and concern over when they will return to the parent company can affect expatriates’ work. Cross-cultural competence refers to the ability of individuals to work effectively and live normally in different cultural contexts, and this ability requires expatriate employees to adopt adaptive thinking patterns and behaviors in the host country. To explore the effect of expatriates’ cross-culture adjustment on their work stress and job involvement, this study therefore uses an empirical approach in which data are collected with a questionnaire survey and proposes specific suggestions, according to the results, to aid expatriates in their personal psychological adjustment. The results show that the challenges faced by expatriate employees are derived from assigned tasks, unknown environments, language barriers, and cultural differences. Excessive pressure will impose ideological and psychological burdens upon the expatriates and even lead to physical symptoms, however, the appropriate amount of pressure can play a driving role and promote the smooth progress of the work. High-tech industry employees who can adapt to the customs and cultures of foreign countries have higher work participation and are more likely to find ways to alleviate work stress. It has also been found that the stronger the cross-cultural competence of employees, the better their adjustment to the host country and the higher their corresponding job performance.

The market competitiveness and sustainable operation of an enterprise are closely correlated with the support of high-tech core technologies in the enterprise. This study first discusses the basic knowledge of core competitiveness, introduces the components and evaluation methods of core competitiveness, and builds an evaluation index system for core competitiveness of high-tech enterprises. Then, the Analytic Hierarchy Process (AHP) is fully discussed, during which the steps, advantages, and disadvantages of the AHP evaluation method are introduced. Finally, the Fujian Province of China is taken as an example, the relevant data are collected and processed, the impact of indicators are analyzed, and a high-tech industry core technological capability analysis indicator system is built based on the AHP method. Thus, the influence of the core technological capabilities of the high-tech industry on the sustainable competitive advantage of the enterprise is obtained. This study puts forward suggestions for maintaining the competitiveness of high-tech industries, thereby improving the competitive advantage of enterprises and achieving the sustainable management of enterprises. The result finds that if the high-tech industries continue to carry out innovation and scientific research, enterprises will maintain their competitive advantages. In summary, exploring the impact of the core technological capabilities of high-tech industries on the sustainable competitive advantages of enterprises is greatly significant for improving their competitiveness and industrial status, which enables them to be invincible in a complex environment.

Purpose: This study aims to propose the corresponding ways and methods to strengthen the environmental moral education based on scientific research methods, rigorous scientific theory and the specific content of environmental moral education. Design/methodology/approach: In this study, taking 360 volunteers of Yangtze University, Hubei, as the research samples, the 32-week (3 h per week) experimental research was preceded in this study. Among the 360 distributed copies of questionnaires, 289 copies are valid, with the retrieval rate 80 per cent. Findings: The research results show significant correlations between environmental education and environmental ethics; environmental ethics and environmental literacy; and environmental education and environmental literacy. Research limitations/implications: The research on the environmental moral education in China was still in the primary stage, and there were few results that can be used for reference. As a result, there was a lack of empirical research in this paper, which needed to be further expanded and improved. Practical implications: This study put forward a series of new judgments and new views to solve the problems, which provided a good theoretical basis for the current education and teaching work of the majority of educators and valuable reference for future research on related topics. This study was helpful to further enhance the environmental moral awareness and environmental moral level. Aiming at the problems existing in environmental moral education, this study proposed a series of solutions to make the whole society, schools and families work together for the improvement and development of environmental moral education. Originality/value: This study was helpful to promote environmental moral quality and level, promote the harmony between man and nature and form a good habit of environmental protection in the whole society.

This study aims to examine the effect of perceived environmental dynamism on entrepreneurial team member’s innovation. Based on the uncertainty reduction theory, this study constructs a multilevel moderated mediation model of the relationship between perceived environmental dynamism and entrepreneurial team member’s innovation. By collecting questionnaires from 117 entrepreneurial team leaders and 479 team members in China, this research found that perceived environmental dynamism could stimulate entrepreneurial team members’ innovation via triggering their information exchange behavior. In addition, entrepreneurial team members’ intolerance for uncertainty and team cooperative climate can moderate the indirect positive relationship between perceived environmental dynamism and individual innovation. Our findings contribute to a better understanding of entrepreneurial team members’ responses to dynamic environment and their innovation behavior.

Energy, economy and ecological environment complement each other. The coupling and coordination development of them would provide basis for the rational use of energy, economic development, and the protection and restoration of the ecological environment. In this study, the coupling and coordination development of the Australian energy, economy, and ecological environment from 2007 to 2016 were quantitatively investigated by constructing a coupling coordination model based on coupling theory. Results showed that: (1) Australia’s comprehensive evaluation index of energy, economy, and ecological environment exhibited an increasing trend. The rising trend of the energy index was obvious, the economy was relatively stable, and the comprehensive evaluation index of the ecological environment strongly fluctuated. (2) The development of energy and the economy, and that of energy and the ecological environment were gradually coordinated, and many unbalanced development patterns were found between the economy and the ecological environment. (3) Four types of coordination were observed in the three subsystems, among them, the barely coordinated categories repeated most often and the coordination degree of the three subsystems tended to grow from the global perspective. Energy, economy, and ecological environment interacted, limited, and promoted one another to form a complex system, through proper coordination, these three subsystems can jointly promote the sustainable development of society in Australia.

Blockchain technology is the most cutting-edge technology in the field of financial technology, which has attracted extensive attention from governments, financial institutions and investors of various countries. Blockchain and finance, as an interdisciplinary, cross-technology and cross-field topic, has certain limitations in both theory and application. Based on the bibliometrics data of Web of Science, this paper conducts data mining on 759 papers related to blockchain technology in the financial field by means of co-word analysis, bi-clustering algorithm and strategic coordinate analysis, so as to explore hot topics in this field and predict the future development trend. The experimental results found ten research topics in the field of blockchain combined with finance, including blockchain crowdfunding, Fintech, encryption currency, consensus mechanism, the Internet of Things, digital financial, medical insurance, supply chain finance, intelligent contract and financial innovation. Among them, blockchain crowdfunding, Fintech, encryption currency and supply chain finance are the key research directions in this research field. Finally, this paper also analyzes the opportunities and risks of blockchain development in the financial field and puts forward targeted suggestions for the government and financial institutions.
