In this book, we consider the problem of achieving the maximum throughput and utility in a class of networks with resource-sharing constraints. This is a classical problem of great importance. In the context of wireless networks, we first propose a fully distributed scheduling algorithm that achieves the maximum throughput. Inspired by CSMA (Carrier Sense Multiple Access), which is widely deployed in today's wireless networks, our algorithm is simple, asynchronous, and easy to implement. Second, using a novel maximal-entropy technique, we combine the CSMA scheduling algorithm with congestion control to approach the maximum utility. Also, we further show that CSMA scheduling is a modular MAC-layer algorithm that can work with other protocols in the transport layer and network layer. Third, for wireless networks where packet collisions are unavoidable, we establish a general analytical model and extend the above algorithms to that case. Stochastic Processing Networks (SPNs) model manufacturing, communication, and service systems. In manufacturing networks, for example, tasks require parts and resources to produce other parts. SPNs are more general than queueing networks and pose novel challenges to throughput-optimum scheduling. We proposes a "deficit maximum weight" (DMW) algorithm to achieve throughput optimality and maximize the net utility of the production in SPNs.

This book aims to provide theoretical and empirical interpretations of certain phenomena in the development of China's cultural industry. Using the film and television industries as the major cases, the author proposes suggestions on China's ongoing development of foreign cultural trade. The author argues that China is well positioned to take full advantage of the opportunities of globalization, to develop its cultural industry in a leapfrog manner. China's rapid economic growth drives the country's development from a small cultural market to a large one. Since it is a middle-income country, its cultural industry still has a relatively large potential to grow. The study on China's foreign cultural trade strategy can contribute to the growing needs of people for a better life and enhance China's "cultural confidence". With an explanation of existing practices, this book also aims to make recommendations on China's strategy for developing foreign cultural trade in the era of globalization. This book will be a good read for students, researchers and scholars of Chinese studies, East Asian studies and culture economics, and those interested in China's film and television industries.
