Explores the social and cultural significance of Chinese communist legal practice in constructing marriage and gender relations in the turbulent period from 1940 to 1960.

Since the mid-1990s, the Internet has revolutionized popular expression in China, enabling users to organize, protest, and influence public opinion in unprecedented ways. Guobin Yang's pioneering study maps an innovative range of contentious forms and practices linked to Chinese cyberspace, delineating a nuanced and dynamic image of the Chinese Internet as an arena for creativity, community, conflict, and control. Like many other contemporary protest forms in China and the world, Yang argues, Chinese online activism derives its methods and vitality from multiple and intersecting forces, and state efforts to constrain it have only led to more creative acts of subversion. Transnationalism and the tradition of protest in China's incipient civil society provide cultural and social resources to online activism. Even Internet businesses have encouraged contentious activities, generating an unusual synergy between commerce and activism. Yang's book weaves these strands together to create a vivid story of immense social change, indicating a new era of informational politics.

This reference book originates from the interdisciplinary research cooperation between academia and industry. In three distinct parts, latest results from basic research on stable enzymes are explained and brought into context with possible industrial applications. Downstream processing technology as well as biocatalytic and biotechnological production processes from global players display the enormous potential of biocatalysts. Application of "extreme" reaction conditions (i.e. unconventional, such as high temperature, pressure, and pH value) - biocatalysts are normally used within a well defined process window - leads to novel synthetic effects. Both novel enzyme systems and the synthetic routes in which they can be applied are made accessible to the reader. In addition, the complementary innovative process technology under unconventional conditions is highlighted by latest examples from biotech industry.

This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Find out more on how to host your own Frontiers Research Topic or contribute to one as an author by contacting the Frontiers Editorial Office: frontiersin.org/about/contact.

Winner of the 2020 PROSE Award for Earth Science! Exploring environmental changes through Earth’s geological history using chemostratigraphy Chemostratigraphy is the study of the chemical characteristics of different rock layers. Decoding this geochemical record across chronostratigraphic boundaries can provide insights into geological history, past climates, and sedimentary processes. Chemostratigraphy Across Major Chronological Boundaries presents state-of-the-art applications of chemostratigraphic methods and demonstrates how chemical signatures can decipher past environmental conditions. Volume highlights include: Presents a global perspective on chronostratigraphic boundaries Describes how different proxies can reveal distinct elemental and isotopic events in the geologic past Examines the Archaean-Paleoproterozoic, Proterozoic-Paleozoic, Paleozoic-Mesozoic, and Mesozoic-Paleogene boundaries Explores cause-and-effect through major, trace, PGE, and REE elemental, stable, and radiogenic isotopes Offers solutions to persistent chemostratigraphic problems on a micro-global scale Geared toward academic and researchgeoscientists, particularly in the fields of sedimentary petrology, stratigraphy, isotope geology, geochemistry, petroleum geology, atmospheric science, oceanography, climate change and environmental science, Chemostratigraphy Across Major Chronological Boundaries offers invaluable insights into environmental evolution and climatic change.

In recent years there has been an outpouring of work at the intersection of social movement thoery, organizational theory, economic, and political sociology. The problems at the core of these areas, Fligstein and McAdam argue, have a similar analytic and theoretical structure. Synthesizing much of this work, A Theory of Fields offers a general perspective on how to understand the problems related to understanding change and instability in modern, complex societies through a theory of strategic action fields.
