This two-volume set constitutes the revised selected papers of the 18th CCF Conference on Computer Supported Cooperative Work and Social Computing, ChineseCSCW 2023 held in Harbin, China, in August 2023. The 54 full papers and 28 short papers presented in these proceedings were carefully reviewed and selected from 221 submissions. The papers are organized in the following topical sections: Social Media and Online Communities; Collaborative Mechanisms, Models, Approaches, Algorithms and Systems; Crowd Intelligence and Crowd Cooperative Computing; Cooperative Evolutionary Computation and Human-like Intelligent Collaboration; Domain-Specific Collaborative Applications.

Driven by the advent of two-dimensional materials, valleytronics is emerging as the next hot field of research in materials science. While the use of charge or spin degrees of freedom in electronic materials as information carriers is familiar and well-appreciated, employment of the valley degree of freedom as an information carrier has remained elusive for many decades. Shortly following the discovery of isolated graphene, 2D semiconductors such as transition metal dichalcogenides were also isolated and investigated. We now understand that these materials can have separately addressable valleys because each valley can be uniquely coupled to a spin state. This imparts the ability to address different valleys (like pseudospins) with electric field, magnetic field, or light, and there is now a real possibility to engineer practical devices based on using valley as the information carrier.Valleytronics in 2D Materials is the first book in the world on the topic of valleytronics. The reader is introduced to the concept via a brief history emphasizing the challenges that impeded its development for so long. We then dive into the valley physics of 2D semiconductors to explain the recent excitement in 2D valleytronics, the scientific investigations to confirm the addressable valleys, and the attempts to engineer valley devices for practical purposes. The text takes on a decidedly practical approach towards the subject, seeking to bring the reader quickly into the field by presenting the minimum theoretical basis for understanding the use of the valley degree of freedom in devices. A selection of key works establishing the scientific underpinnings of valley addressability and control are described to help the reader grasp the current stage of understanding, the technical foundations established, and the open questions. The renewal in valleytronics is yet unfinished, but with more than a decade of research and engineering efforts devoted in recent times, this book seeks to provide a timely reference for students, scientists and engineers to join this exciting journey and perhaps help to create the next disruption in information technology.

Despite globalizing forces, whether economic, political, or cultural, there remain conspicuous differences that divide scholarly communities. How should we understand and respond to those discursive gaps among different traditions and systems of knowledge production? Critical Zone is a book series in cultural and literary studies that is concerned with current critical debates and intellectual preoccupations in the humanities. The series aims to improve understanding across cultures, traditions, discourses, and disciplines, and to produce international critical knowledge. Critical Zone is an expression of timely collaboration among scholars from Hong Kong, mainland China, the United States, and Europe, and conceived as an intellectual bridge between China and the rest of the world. The second volume of Critical Zone, as does its predecessor, consists of two parts. The first part includes original essays that deal with the concept and practice of “empire,” as a collective response to the question of how imperial formations and operations, in the past and at present, should be examined in a larger context of international politics and how historical imperialism may be considered in relation to the conditions of our time. Part II includes two sets of translations of essays, first published in Chinese, about two recent debates in China: one on the canonicity of Lu Xun and the other on the problem of how to reform Peking University in the context of globalization. These two groups of translations are led by review essays that contextualize the debates.

Amid the globalizing forces, whether economic, political, or cultural, there remain conspicuous differences and divergences that divide and antagonize scholarly communities. How should we understand and respond to those discursive gaps among different traditions and systems of knowledge production? Critical Zone is a book series that is envisaged as a forum where communities of critical scholarship can come together to share ideas and participate in the debates that preoccupy the humanities today. The series aims to improve understanding across cultures, traditions, discourses, and disciplines and to produce international critical knowledge. Critical Zone is an expression and an embodiment of timely collaboration among scholars in Hong Kong, mainland China, the United States and Europe and is conceived as an intellectual bridge between China and the rest of the world. Each volume in the series has two sections. The first section contains original articles on a set of related topics by scholars from around the world; the second section includes review essays highlighting one or two issues in regional critical scholarship and translations that reflect intellectual trends and concerns in the region, in particular in China.

This volume is a collection of refereed papers based on the presentations made at the Third Conference on East Asia and Western Pacific Meteorology and Climate. The topics discussed at the Conference included the East Asian monsoon and climate, typhoons, and air-sea interactions. The majority of the papers were contributed by scientists from mainland China, Taiwan and Hong Kong, the rest were invited papers from leading non-Chinese meteorologists in the field. This set of proceedings, the third in the series, is an important update of the two previous volumes and serves as a valuable reference on the latest research into the meteorology and climate of the East Asia and Western Pacific region.
