Abstract Migration is on the rise globally, and education is a major cause of cross-border movements. In the realm of the long-standing cultural differences among international students, the existing research by most western scholars shows the neglect of study on cultural adaptability of African students, particularly on the dual identity of being both foreigners and students. This research focuses on the cross-cultural adaptation of Cameroonian students, adopting both qualitative and quantitative research methods, emphasizing on the following three aspects: First, the current status of Cameroonian students in China, including their psychological adaptability to cross culture, academic achievement and social life. Second, the factors influencing cross-cultural adaptation of Cameroonian students in China. Third, the coping strategies for Cameroonian students’ cross-cultural conflicts. The research contributes to work on Sino-African experiences and more broadly to responses to China’s globalizing strategy.

Nowadays it is common for women to serve as university presidents and other high-level officials. Many women undertake leadership of universities, shouldering the important responsibilities of managing universities and promoting the construction and development of these institutions. This article investigates the female leaders in 38 leading universities in China. Leaders in the study are defined as presidents, vice-presidents, party secretaries and deputy party secretaries, as executive leaders and party leaders have similar ranks and authority within universities in China. By investigating their personal characteristics, this article draws an overall portrait of female leaders in leading universities in China. They are on average 54 years old, have high educational and academic achievement, are promoted principally from internal channels, most of them are deputies, and women on higher positions are more likely on the party track rather than the executive track. This article also discusses the role of female leaders in the field of higher education.

The construction of lunar bases is a critical part of the in-depth implementation of lunar exploration missions, which poses great challenges due to the complex environment of the lunar surface and the high consumption of human resources. It is highly promising to employ multiple autonomous robots as the main body to execute construction-related complex tasks, such as inspection, transportation, building and so on, which requires the collaborative path planning for the robot team to meet the inherent temporal requirements of those tasks. This paper develops a controller synthesis method to plan obstacle-avoidance paths that not only satisfies temporal constraints of construction tasks, but also ensures the long-term autonomy of each robot in the team from the perspective of energy consumption. Firstly, linear temporal logic and model checking tools are used to generate reachability sequences that satisfy the specification regarding to the robot team’s global task. Secondly, this reachability sequence is formulated as a set of quadratic programming problems. By encoding the safety and reachability constraints into the controller through the control barrier function, trajectories that are both safe and satisfying temporal constraints are planned for multiple robots. In addition, our controller synthesis approach can also successfully solve the path planning problem of multiple robots subject to survival constraints. By the dedicated design of the energy-constrained barrier functions, we obtain a control strategy that guarantees long-term autonomy. Finally, in our simulation four robots are employed to accomplish the lunar base construction tasks described through LTL in two different obstacle environments, and the team performs the task for more than half an hour where every fully-charged robot can only work about forty-five seconds. The trajectories in the simulation results verify the feasibility and effectiveness of our proposed methods. • For the multi-robot path planning in complex tasks, we propose a global framework combining control barrier functions and linear temporal logic. • To address the energy optimization problem, we transform the robot recharging constraint into an linear temporal logic formulation. • In the context of lunar base construction, this paper verifies the effectiveness of the framework through experimental simulation.

The tourism economy is inseparably linked to the ecological environment, serving as a “green engine” in the promotion of the low-carbon transition of cities and the realization of high-quality economic development. Taking the implementation of a low-carbon city pilot (LCCP) policy as a quasinatural experiment, we assess the impact of a low-carbon transition on the urban tourism economy using a time-varying difference-in-differences identification strategy based on the panel data of 279 Chinese cities covering the period from 2007 to 2019. The results indicate that LCCPs have a favorable effect on the development of the tourism economy. Compared to non-pilot cities, the implementation of LCCPs has led to an average increase of approximately CNY 1918 in tourism receipts per inhabitant in pilot cities. The mechanism analysis reveals that the implementation of LCCPs promotes the tourism economy by energizing the tourism market and accumulating ecological wealth. Specifically, LCCPs have not only optimized the supply of tourism products and related services but have also improved the competitiveness of regional tourism by energizing the tourism market. Meanwhile, LCCPs have improved the ecological environment and enriched natural resources through the accumulation of urban ecological wealth, thereby enhancing urban tourism attractiveness and environmental carrying capacity. The heterogeneity results show that the impact of LCCPs on the tourism economy varies significantly by tourism resource endowment, border-crossing status, and ecological landscape division. Our findings provide empirical evidence that can be used to promote the tourism economy in other countries and facilitate the industrial transformation during the process of a low-carbon transition.

This paper discussed the control strategy after cross-border acquisition of Chinese enterprises from the perspective of institutional theory. Isomorphic behavior of organization driven by external legitimacy influence the control strategy after cross-border acquisition of Chinese enterprises; while path dependent behavior driven by internal legitimacy influence the control strategy after cross-border acquisition of Chinese enterprises; institutional distance under the action of legitimacy has a moderating effect on the relationship between control strategy and acquisition performance. On this basis,this paper proposes the model of relationship between control strategy and performance after cross border acquisition of Chinese enterprises.
