This unique volume focuses on the development of Chinese as a Second Language (CSL) teachers in the global context. It addresses the specific issues and challenges faced by CSL teachers and demonstrates international practices in the field. It also provides a comprehensive examination of their multifaceted professionalism from diverse perspectives.With the rise of China as a political and economic power, learning CSL has increasingly gained its popularity in a global context. According to the Chinese International Education Foundation, by 2023, the number of registered Chinese language learners exceeded 12.5 million. Due to the shortage of teachers, the Ministry of Education in China launched the International Chinese Language Teachers Volunteer Program in 2004. By 2021, more than 61,000 volunteer Chinese language teachers had been dispatched to more than 151 regions and countries. Many more overseas universities, colleges, and higher institutes now have established CSL programmes at both undergraduate and postgraduate levels to cultivate local CSL teachers. However as the number of CSL learners continues to grow, the need for high-quality Chinese language teachers has become more urgent than ever. Responding to CSL teachers’ challenges of delivering Chinese language and culture to learners from diverse language and cultural backgrounds, this book explores four interrelated themes: 1) CSL teachers’ professional development in the global context, 2) CSL teachers’ motivation, agency, and identity, 3) CSL teachers’ knowledge and practice in multicultural and multilingual contexts, and 4) CSL teachers’ technological literacy and agency in the digital era.With its focus on both the internal and external complexities of CSL teacher development, the book offers timely insights and practical guidance for researchers, educators, policymakers, and frontline teachers working in this rapidly expanding field.

However, the openness and weak communication characteristics of USNs make underwater localization much more challenging in comparison to terrestrial sensor networks. In this book, we focus on the localization problem in USNs, taking into account the unique characteristics of the underwater environment.

Autonomous underwater vehicles (AUVs) are emerging as a promising solution to help us explore and understand the ocean. The global market for AUVs is predicted to grow from 638 million dollars in 2020 to 1,638 million dollars by 2025 – a compound annual growth rate of 20.8 percent. To make AUVs suitable for a wider range of application-specific missions, it is necessary to deploy multiple AUVs to cooperatively perform the localization, tracking and formation tasks. However, weak underwater acoustic communication and the model uncertainty of AUVs make achieving this challenging. This book presents cutting-edge results regarding localization, tracking and formation for AUVs, highlighting the latest research on commonly encountered AUV systems. It also showcases several joint localization and tracking solutions for AUVs. Lastly, it discusses future research directions and provides guidance on the design of future localization, tracking and formation schemes for AUVs. Representing a substantial contribution to nonlinear system theory, robotic control theory, and underwater acoustic communication system, this book will appeal to university researchers, scientists, engineers, and graduate students in control theory and control engineering who wish to learn about the core principles, methods, algorithms, and applications of AUVs. Moreover, the practical localization, tracking and formation schemes presented provide guidance on exploring the ocean. The book is intended for those with an understanding of nonlinear system theory, robotic control theory, and underwater acoustic communication systems.

With the rapid development of robotics and communication technologies, maritime unmanned systems (MUSs) have emerged as a critical research domain due to their unprecedented capabilities in oceanographic data collection, environmental monitoring, and marine ecosystem studies. Specifically, MUSs refer to interoperable robotic systems operating synergistically in aerial, surface and underwater environments. At present, MUSs exhibit the characteristics of diversified sensing resources, decentralized architectures, and systematic coordination, making the detection-communication-control crucial for efficient operations and multi-mission adaptability. However, the traditional research predominantly adopts separate design approaches for detection, communication and control in MUSs. The separate design creates dual constraints: the detection-communication interactions lack effective feedback mechanisms while the control commands become vulnerable to information incompleteness. To address the above issue, it is urgent to co-design the detection, communication and control for MUSs. This research direction has profound strategic significance and long-term value for the future development and application of marine technology.This book is devoted to present the cutting-edge results on the integrated design of detection, communication, and control for MUSs. It first elaborates on the basic concepts of detection, communication and control in maritime environment. After that, it presents several integrated design solutions for the detection, communication, and control in MUSs, including detection-communication integration, detection-control integration, communication-control integration, and detection-communication-control integration. Finally, this book concludes with practical applications of these integrated design methodologies in modern port monitoring systems, demonstrating their effectiveness in real-world maritime scenarios.The book provides actionable insights of developing next-generation MUSs for the researchers, engineers, and practitioners in maritime robotics, autonomous systems, and networked control. A background in control theory, signal processing, or wireless communication is recommended to fully grasp the advanced techniques. Whether you're advancing academic research or optimizing industrial systems, this book equips you with cutting-edge tools to push the boundaries of maritime autonomy.
