Exposure to Engineered Nanomaterials in the Environment provide a new, holistic framework for testing and evaluating the potential benefits and risks of engineered nanomaterials (ENMs), including their potential socioeconomic impacts, ethical issues and consumers' expectations and fears. The book covers nanomaterial presence in various environments, agroecosystems and other areas within the human sphere of actions. The book includes sections on (i) Chemical, physical and biological properties, (ii) Presence and diffusion of ENMs in human environments, agriculture, food and drug products, (iii) ENMs as a pillar in biological and medical research, and (iv) Social and regulatory issues emerging from years of application. The book is designed to increase awareness to key end-users and stakeholders, including food producers and processors, industry, representatives of society and consumers, and those looking to implement an accurate and effective risk analysis procedure that promotes the sustainable use of nanotechnology.

This monograph presents a comprehensive treatment of important new ideas on Dirac operators and Dirac cohomology. Dirac operators are widely used in physics, differential geometry, and group-theoretic settings (particularly, the geometric construction of discrete series representations). The related concept of Dirac cohomology, which is defined using Dirac operators, is a far-reaching generalization that connects index theory in differential geometry to representation theory. Using Dirac operators as a unifying theme, the authors demonstrate how some of the most important results in representation theory fit together when viewed from this perspective. An excellent contribution to the mathematical literature of representation theory, this self-contained exposition offers a systematic examination and panoramic view of the subject. The material will be of interest to researchers and graduate students in representation theory, differential geometry, and physics.

With China's rapid advancements in urbanization and industrialization, there has been significant labor movement away from agriculture in the rural regions. Using four village case studies, Song examines how this restructuring process affects the rural population. Much of her research is centered on their various perceptions and reactions towards the market reforms. How are their lives reshaped through the employment transition? Along with the changes of family life and the diversification of development models, how do an individual's gender and background play a role in determining employment? These are the broad questions that Song addresses through detailed analysis of four different villages, in light of China's move towards decentralization of its rural economy.
