Drawing on archival as well as rich interview material, John F. Lyons examines the role of Chicago public schoolteachers and their union, the Chicago Teachers Union (CTU), in shaping the policies and practices of public education in Chicago from 1937 to 1970. From the union's formation in 1937 until the 1960s, the CTU was the largest and most influential teachers' union in the country, operating in the nation's second largest school system. Although all Chicago public schoolteachers were committed to such bread-and-butter demands as higher salaries, many teachers also sought a more rigorous reform of the school system through calls for better working conditions, greater classroom autonomy, more funding for education, and the end of political control of the schools. Using political action, public relations campaigns, and community alliances, the CTU successfully raised members' salaries and benefits, increased school budgets, influenced school curricula, and campaigned for greater equality for women within the Chicago public education system. Examining teachers' unions and public education from the bottom up, Lyons shows how teachers' unions helped to shape one of the largest public education systems in the nation. Taking into consideration the larger political context, such as World War II, the McCarthy era, and the civil rights movements of the 1960s, this study analyzes how the teachers' attempts to improve their working lives and the quality of the Chicago public school system were constrained by internal divisions over race and gender as well as external disputes between the CTU and the school administration, state and local politicians, and powerful business and civic organizations. Because of the obstacles they faced and the decisions they made, unionized teachers left many problems unresolved, but they effected changes to public education and to local politics that still benefit Chicago teachers and the public today.

The past few years have seen considerable advances in our understanding of the molecular basis underlying cutaneous cell adhesion mechanisms. Co-authored by a number of leading experts in the field ^Cell Adhesion and Migration in Skin Disease provides a comprehensive overview of the critical role played by cell adhesion in determining the structure and function of both healthy and diseased human skin. The book is divided into three main sections, with each one addressing a principal function of adhesion molecules. The first part focuses on the epidermis, which as the skin's outermost layer, acts as the human body's primary barrier of defence. Roles played by cytoskeletal intermediate filaments and junctional complexes in cutaneous cell adhesion are emphasised with descriptions of blistering skin diseases that can arise if these molecules malfunction. The second part describes the macromolecular interactions responsible for the anchorage of cells to the underlying extracellular basement membrane. The experimental approaches detailed in the text not only reveal how the molecular components of the dermal-epidermal junction have been elucidated, but also highlight how mutations in the genes which encode these molecules are responsible for many heritable skin diseases. Leukocytes continually infiltrate the skin and patrol it for potentially harmful pathogens. Control of leukocyte adhesion to resident cells within the skin and to the extracellular matrix plays a key role in controlling these processes. These mechanisms constitute the primary focus of the final section. The pivotal role of leukocytes is examined in conjunction with the chronic inflammatory diseases which arise when components of the skin's finely tuned defence strategy go awry and the potential for these anomalies to be pinpointed as important immunotherapeutic targets for skin diseases.

SiGe HBT BiCMOS technology is the obvious groundbreaker of the Si heterostructures application space. To date virtually every major player in the communications electronics market either has SiGe up and running in-house or is using someone else’s SiGe fab as foundry for their designers. Key to this success lies in successful integration of the SiGe HBT and Si CMOS, with no loss of performance from either device. Filled with contributions from leading experts, Fabrication of SiGe HBT BiCMOS Technologies brings together a complete discussion of these topics into a single resource. Drawn from the comprehensive and well-reviewed Silicon Heterostructure Handbook, this volume examines the design, fabrication, and application of silicon heterostructure transistors. A novel aspect of this book the inclusion of numerous snapshot views of the industrial state-of-the-art for SiGe HBT BiCMOS technology. It has been carefully designed to provide a useful basis of comparison for the current status and future course of the global industry. In addition to the copious technical material and the numerous references contained in each chapter, the book includes easy-to-reference appendices on the properties of Si and Ge, the generalized Moll-Ross relations, integral charge-control relations, and sample SiGe HBT compact model parameters.
