This book provides an example of the capitalization of computer and wiki technology to support collaborative writing among Mainland Chinese upper primary school students. It presents the results of a study showing the application of the Design-Based Research (DBR) methodology to design a Wiki-based Collaborative Process Writing Pedagogy (WCPWP) to help students with their writing in the Chinese context. The WCPWP is designed and developed based on social constructivist theory and the social view of writing process theory, as well as in consideration of the Technological, Pedagogical, and Content Knowledge (TPACK) framework.Primarily aimed at researchers and practitioners in the fields of collaborative learning, TPACK, and Chinese writing, as well as Chinese language educators, this book will also deepen primary educators' understanding of the links among technology, pedagogy and content, and guide educators in the integration of social media, as well as the design of effective matching pedagogic strategies, in their teaching of writing.

Technology transfer studies are usually framed through Economics and Management Sciences, but this volume Geography of Technology Transfer in China seeks to reveal the mechanism of technology transfer from the geographical perspective. It not only depicts the spatial evolution laws of glocal technology transfer networks, but also uses regression models to uncover the two-way effects between the networks and innovative capacity. In addition, this book highlights the integration and interaction of networks on both the global and local scales. A theoretical framework on glocal networks of technology transfer is established based on a series of economic geography bases in order to depict the spatial differences and coupling mechanism among multi-scaled networks in China.This book consists of 5 parts and 10 chapters, which illustrate the background, theoretical basis, spatial evolution, dual-way influences, and policy implications of technology transfer in China, presenting a clear structure both theoretically and empirically. The book begins with the 'what', 'why', and 'how' questions behind geographical studies on technology transfer to clarify the purpose of the book and its differentiation from present technology transfer studies. Thereafter, it discusses the 'holy trinity' framework of glocal technology transfer networks consisting of cultural, territorial, and networked subsystems. To this end, the spatial evolution of the technology transfer is highlighted through soical network analysis, which aims at depicting the geographical rules of China's technology transfer networks at global, domestic, and regional scales. Based on these discoveries, the next part of the book further analyzes, through a series of regression models such as ERGM and NBRM, the kinds of determinants which have influenced the network size and how the network has in turn affected local innovation capacity . Lastly, the policy implications connect the findings of empirical studies with the operability of the national innovation system. On the whole, this book extensively covers the theoretical, empirical, and practical applications of the geography of technology transfer in China.

As mobile devices continue becoming a larger part of our lives, the development of location acquisition technologies to track moving objects have focused the minds of researchers on issues ranging from longitude and latitude coordinates, speed, direction, and timestamping, as part of parameters needed to calculate the positional information and locations of objects, in terms of time and position in the form of trajectory streams. Recently, recent advances have facilitated various urban applications such as smart transportation and mobile delivery services.Unlike other books on spatial databases, mobile computing, data mining, or computing with spatial trajectories, this book is focused on smart transportation applications.This book is a good reference for advanced undergraduates, graduate students, researchers, and system developers working on transportation systems.

This dissertation delves into the emerging trend of database migration to the cloud, focusing on the evolution, challenges, and innovations in cloud-native Online Transaction Processing (OLTP) systems. With the increasing shift of businesses towards cloud databases, driven by benefits like cost efficiency, scalability, and advanced features like fault tolerance and security, there is a growing preference for Database as a Service (DBaaS). Initially, cloud providers deployed traditional database software such as PostgreSQL and MySQL in the cloud. To enhance their competitive edge in terms of cost and elasticity, they introduced cloud-native databases designed specifically for cloud environments. A key design principle in these cloud-native databases is disaggregation, which involves separating components into distinct sub-services for independent scaling and billing. This approach improves resource utilization, reduces operational costs, and supports cloud deployment by reusing existing sub-services. Compute-storage disaggregation, or storage disaggregation, is a prominent architecture in modern cloud-native OLTP systems, connecting compute and storage clusters via a network. This storage-disaggregation architecture presents new opportunities and challenges. It allows for leveraging Storage as a Service (STaaS) in the cloud, offered by major providers with diverse interfaces and features. However, it also introduces increased latency in I/O operations. This necessitates a revision of traditional database designs to exploit new opportunities and address these challenges. This dissertation focuses on three key aspects of transaction processing: index, atomic commit, and concurrency control. We first explore index designs in the context of storage disaggregation. Introducing Bonsai, a two-fold index design which maintains an index in compute-side memory optimized for hot data accesses while offloading cold data accesses to the index embedded in nowadays storage services. Bonsai reduces network traffic and improves throughput. Next, we reevaluate atomic commit protocols in a partitioned database, specifically the two-phase commit (2PC), in a storage disaggregation architecture. We propose Cornus, an optimized 2PC protocol tailored for STaaS, addressing its inherent latency and blocking issues. Lastly, we address the challenge of concurrency control in high-contention scenarios, a significant concern as databases migrate to the cloud. We present Bamboo, a pessimistic concurrency control protocol, which enhances parallelism under high contention while maintaining correctness. This research aims to inspire database developers to rethink traditional designs in the context of evolving cloud-native OLTP databases, potentially establishing new principles for next-generation cloud-native database systems.
