China has achieved remarkable economic success in the past three decades and has become the second-largest economy in the world after the United States. However, accompanying this rapid economic growth is an increasing income inequality. In recent years, China's income disparity has reached an alarming level, making it one of the countries with the most unequal income distribution in the world.The widening income gap is the root cause of many issues in contemporary China. How should China step up distribution system reform? How should China deepen the reforms to its fiscal and tax systems? Should the government increase wages to achieve the income multiplication plan? What is the fundamental measure to tackle income disparity issues in China? With in-depth analysis and empirical studies on these questions, this book provides comprehensive perspectives on China's income disparity issues that most international scholars are concerned about.

This book gives an account of the necessary background for group algebras and crossed products for actions of a group or a semigroup on a space and reports on some very recently developed techniques with applications to particular examples. Much of the material is available here for the first time in book form. The topics discussed are among the most classical and intensely studied C*-algebras. They are important for applications in fields as diverse as the theory of unitary group representations, index theory, the topology of manifolds or ergodic theory of group actions. Part of the most basic structural information for such a C*-algebra is contained in its K-theory. The determination of the K-groups of C*-algebras constructed from group or semigroup actions is a particularly challenging problem. Paul Baum and Alain Connes proposed a formula for the K-theory of the reduced crossed product for a group action that would permit, in principle, its computation. By work of many hands, the formula has by now been verified for very large classes of groups and this work has led to the development of a host of new techniques. An important ingredient is Kasparov's bivariant K-theory. More recently, also the C*-algebras generated by the regular representation of a semigroup as well as the crossed products for actions of semigroups by endomorphisms have been studied in more detail. Intriguing examples of actions of such semigroups come from ergodic theory as well as from algebraic number theory. The computation of the K-theory of the corresponding crossed products needs new techniques. In cases of interest the K-theory of the algebras reflects ergodic theoretic or number theoretic properties of the action.
The authors of this book - teachers of foundation courses to pre-service and in-service teachers in Canada, Israel, and the United States - use culturally heterogeneous settings as points of departure for inquiry and cross-cultural encounters of difference, and illuminate how, among people of differing ethnic, religious, socio-economic, political, ideological, and gendered backgrounds, the telling of experiential stories can shift personally and culturally polarized positions. Key in the work documented here is the encouragement of narrative rather than argumentative modes of expression: the instructors found inquiry more likely to stay alive when they were able to access and incorporate both the mutual interest of and the personal tensions between their students. The book illustrates how personal dynamics can subtly move individual inquiry forward, and help alleviate animosity and polarization.
In recent years, unemployment rates in some ECCU countries have been among the highest globally. This paper evaluates several factors that could explain them, finding that high unit labor costs, in a context of strong unionization, are significantly associated with high structural unemployment, while the global crisis added a cyclical component. Our analysis also suggests that high-paid jobs in the public and tourism sectors, which have been growing considerably in recent decades, could have increased the reservation wage and lowered labor force participation. We find no indication that high structural unemployment is related to the phase out of EU preferences on bananas/sugar exports or to a skills mismatch. As expected, unemployment has been substantially, but only temporarily fueled by large natural disasters.
This book reports on the findings of a series of studies on the development of zero-to-three-year-old Chinese children supported by the Fundamental Research Funds for the Central Universities. The studies were conducted by a research group at the Institute of Early Childhood Education, Beijing Normal University. In the first part of the book, findings concerning the developmental trajectory are presented, including physical and motor development, cognitive development, language development, social and emotional development. The focus of the second part is on the effect of family environment and practices. Specifically, the authors provide empirical evidence allowing readers to better understand how the home environment and educational practice in the family impact the psychological development of children in their early years. In the last part, culture-specific issues like the new universal two-child policy in China are discussed. Most of the parts are based on large-scale investigations and analysis of the status quo, complemented by small-sample studies and case studies. The findings presented here will promote theory building and public understanding of early care and education in China. Moreover, the behavior observation scales and assessment tools developed by the research group are cultural appropriate and may serve as a foundation for further studies on early care and education in the Chinese cultural context.
This paper documents the two debt restructurings that Grenada undertook in 2004–06 and 2013–15.Both restructurings emerged as a consequence of weak fiscal and debt situations, whichbecame unsustainable soon after external shocks hit the island economy. The two restructurings provided liquidity relief, with the second one involving a principal haircut. However, the first restructuring was not able to secure long-term debt sustainability. Grenada’s restructuring experience shows the importance of (1) establishing appropriate debt restructuring objectives; (2) committing to policy reforms and maintaining ownership of the restructuring goals; and (3) engaging closely and having clear communications with creditors.

Carbon nanotubes (CNTs) possess the unique combination of extreme mechanical and physical properties at the level of the individual tube. They are often considered one of the best candidates for the reinforcement of the next generation of multifunctional composite materials. It is essential to assemble the CNTs into macroscopic assemblies resembling traditional fiber-reinforced composites to begin to realize their potential and make them a serious candidate for commercial composite structures. This chapter presents a general introduction to aligned and high-volume fraction CNT composites and then explores two recent promising approaches for fabricating strong, stiff and multifunctional aligned CNT/polymer composite prepregs at satisfactory processing rates. One approach involves incorporating drawable superaligned CNT sheets into high-volume fraction composites through spraying or spray-stretching and winding. The other approach is based on directly shear pressing vertically aligned CNT arrays into horizontally aligned sheets with subsequent polymer infiltration. Both approaches produced CNT composite prepregs with desirable structural features and excellent properties. Aligned CNT/bismaleimide composites produced by stretch winding exhibited a combined tensile strength and elastic modulus exceeding carbon fiber composites. The exceptional mechanical performance coupled with unique electrical and thermal properties makes these materials promising for a wide range of applications, such as multifunctional composite structures, lightweight and flexible conductors, thermal interface materials, and sensors.
