Adverse environmental factors can impose stress on plants and influence the expression of the full genetic potential for growth and reproduction. The capability of plants to develop plastic response reactions, to adapt to environmental stress situations, is unique in the biological world. A goal of the research described in this volume is to increase crop productivity, particular in regions where the environment imposes stress. An understanding of the principles involved in plant adaptation to environmental stress will enable optimisation of practices to improve agronomic production and minimise damaging environmental impact. The aim of this volume is to link the rapidly advancing and increa...

How do schools and public history influence each other? Cases studies focusing on school and public history around the world shed light on the intricate relationships between schools, students, teachers, policy makers and public historians. From why Robben Island is not included in South African curriculum to how German schools shape Holocaust memory, the case studies offered in this book sheds light on a current topic.
Lay prophets in Lutheran Europe (c. 1550–1700) is the first transnational study of the phenomenon of angelic apparitions in all Lutheran cultures of early modern Europe. Jürgen Beyer provides evidence for more than 350 cases and analyses the material in various ways: tracing the medieval origins, studying the spread of news about prophets, looking at the performances legitimising their calling, noting their comments on local politics, following the theological debates about prophets, and interpreting the early modern notions of holiness within which prophets operated. A full chronology and bibliography of all cases concludes the volume. Beyer demonstrates that lay prophets were an accepted part of Lutheran culture and places them in their social, political and confessional contexts.
While information on the roles and regulation of transporters for all major nutrients and metabolites in plants has increased significantly, a synthesis of this research has been lacking. Based on current research in genomics and proteomics, this book cla
The ability to control the rates of metabolic processes in response to changes in the internal or external environment is an indispensable attribute of living cells that must have arisen with life’s origin. This adaptability is necessary for conserving the stability of the intracellular environment which is, in turn, essential for maintaining an efficient functional state. The advent of genomics, proteomics, and metabolomics has revolutionised the study of plant development and is now having a significant impact on the study of plant metabolism and its control. In the last few years, significant advances have been made, with the elucidation of enzyme gene families and the identification of...
The growing body of literature on ethnic businesses has emphasized the importance of small family-based businesses as a key form of immigrant adaptation. Although there have been numerous references to the importance of "family labor" as a key ethnic resource, few studies have examined the work roles and family dynamics entailed in various kinds of ethnic businesses. Helping Out addresses the centrality of children's labor participation in such family enterprises. Discussing the case of Chinese families running take-out food shops in Britain, Miri Song examines the ways in which children contribute their labor and the context in which children come to understand and believe in "helping out" as part of a "family work contract." Song explores the implications of these children's labor participation for family relationships, cultural identity, and the future of the Chinese community in Britain. While doing so, she argues that the practical importance and the broader meanings of children's work must be understood in the context of immigrant families' experiences of migration and ethnic minority status in Western, white-majority societies.
The assimilation of sulfur in higher plants and its reduction in metabolically important sulfur compounds are crucial factors determining plant growth and vigor and resistance to stresses. The present book discusses the aspects of sustainable crop production with sulfur, the importance of sulfur metabolites and sulfur metabolizing enzymes in abiotic stress management in plants. The book provides the most up-to-date reference on sulfur assimilation in plants.
