Language is a symbolic system of meanings evoked by linguistic forms. The choice of forms in communication is non-arbitrary. Rather, speakers pick those forms whose meanings best convey their discourse intention. The meaning of the Mandarin ba-construction, argues Jing-Schmidt, is discourse dramaticity, a concept that includes high conceptual salience and subjectivity. The ba-construction and its "syntactic variations" are never interchangeable because contrast in their meanings determines difference in their functions. Quantitative analyses based on authentic data validate the postulation of discourse dramaticity. By taking discourse pragmatics seriously, the dramaticity hypothesis enables a unitary explanation that transcends sentence grammar. The diachronic treatment reveals the syntactic change of the ba-construction as an adaptive process of pragmatization, which raises the issue of linguistic evolution as a result of socio-cultural development. This book will be of particular value to readers interested in the interaction between grammar and pragmatics and to teachers confronting the controversy of the ba-construction in foreign language pedagogy.

This book highlights the intrinsic structures of all kinds of energetic compounds and some structure–property relationships therein. Energetic materials are a class of energy materials that can transiently release a large amount of gases and heat by self-redox after stimulated and usually refer to explosives, propellants and pyrotechnics. Nowadays, in combination with various theories and simulation-aided material design technologies, many new kinds of energetic materials like energetic extended solids, energetic ionic salts, energetic metal organic frames, energetic co-crystals and energetic perovskites have been created, in addition to traditional energetic molecular crystals. It is somewhat dazzling, and an issue of how we can understand these new types of energetic materials is raised. In the past about 20 years, we were immersed in the computational energetic materials. By means of defining a concept of intrinsic structures of energetic materials, which refers to the crystal packing structure of energetic materials, as well as molecule for molecular solid specially, the microscopic structures have been mostly clarified, and related with many macroscopic properties and performances, with molecular simulations. This book presents our understanding about it. Thereby, a simply and new way to readily understand energetic materials is expected to be paved, based on this book. It contains energetic molecular crystals, energetic ionic crystals, energetic atomic crystals, energetic metallic crystals and energetic mixed-type crystals and the substructures closest to crystal packing. Meanwhile, the common intermolecular interactions in energetic crystals will be introduced. In addition, theoretical and simulation methods for treating the intrinsic structures will be briefed, as they are the main tools to reveal the molecules and crystals. Besides, the polymorphism as a level of intrinsic structures will be briefly discussed. In the final of this book, we introduce the crystal engineering of energetic materials. This book features the first proposal of intrinsic structure and crystal engineering of energetic materials and the understanding of the properties and performances of energetic materials by maintaining a concept that structure determines property. It helps to promote the rationality in creating new energetic materials, rather than increase experience.

With the increasing complexity of and dependency on software, software products may suffer from low quality, high prices, be hard to maintain, etc. Software defects usually produce incorrect or unexpected results and behaviors. Accordingly, software defect prediction (SDP) is one of the most active research fields in software engineering and plays an important role in software quality assurance. Based on the results of SDP analyses, developers can subsequently conduct defect localization and repair on the basis of reasonable resource allocation, which helps to reduce their maintenance costs. This book offers a comprehensive picture of the current state of SDP research. More specifically, it introduces a range of machine-learning-based SDP approaches proposed for different scenarios (i.e., WPDP, CPDP, and HDP). In addition, the book shares in-depth insights into current SDP approaches’ performance and lessons learned for future SDP research efforts. We believe these theoretical analyses and emerging challenges will be of considerable interest to all researchers, graduate students, and practitioners who want to gain deeper insights into and/or find new research directions in SDP. It offers a comprehensive introduction to the current state of SDP and detailed descriptions of representative SDP approaches.

Why investment and financial reform are essential to China's continued economic well-being Although China's economy has grown spectacularly over the last twenty-five years, economists disagree about how the Chinese economy is likely to fare in the short- and long-term future. Is China's growth sustainable, or has China relied too much on investment, which is subject to diminishing returns, and not enough on technological change? The first book on the relation between investment, finance, and growth in China, How China Grows dismisses this concern. James Riedel, Jing Jin, and Jian Gao argue that investment has not only been the engine of growth, but also the main source of technological progress and structural change in China. What threatens future growth instead, the authors argue, are the weaknesses of China's financial system that undermine efficiency in investment allocation. Financial-sector reform and development are necessary, not only for sustaining long-term growth, but also for maintaining macroeconomic stability. Although it includes some technical economic analysis, How China Grows is accessible to noneconomists and will benefit anyone who is interested in development finance in general and in China's economic growth in particular—whether economists, political scientists, bankers, or business people.

This book represents one of the first attempts by a multidisciplinary research team, encompassing the social sciences, business, architecture and planning, engineering, and finance and economics, to help rural communities discover sustainable and self-reliant paths to development and transformation. The opening chapter outlines the background of the research, its importance in the context of China and other countries, the rationale for choosing the case study communities in rural China, and the composition of the research team. Chapter 2 explores key issues in the role of social entrepreneurship and leadership in rural community development. Chapter 3 analyses a green platform for a pilot transaction of China forest carbon sinks led by the Huadong Forestry Exchange. The fourth chapter examines carbon trade, forestry land rights, and the livelihoods of farmers in rural Chinese communities. Chapter 5 explores alternative energy development in rural Chinese communities, where the poor are often disproportionately dependent on fuel wood and solid biomass, causing environmental degradation, reduced productivity and the decline of income generating opportunities. Chapter 6 examines and tests the proposition that stronger communities will result from ‘connected up’, holistic, synergistic and inclusive planning of services and supporting infrastructure. Chapter 7 analyzes information and communications technology (ICT) based service innovations for supporting rural community enterprises. Chapter 8 highlights key elements of stronger rural communities, drawing together the themes and proposals of preceding chapters and constructing an integrated model. The authors demonstrate that interconnected community enterprises based on clean forest products, forest carbon and ecotourism can be underpinned by local infrastructure enterprises such as renewable energy, water, waste management, ICT and transport, and financial mechanisms like carbon finance, all involving skills development, leadership and social entrepreneurship coupled with corporate and investment partnerships. Such interconnected approaches are expected to generate increased employment and prosperity, improve social livelihoods, and benefit the environment.
