• Sommario/riassunto: Quantum chromodynamics is the fundamental theory of strong interactions. It is a physical theory describing Nature. <i>Lectures on Quantum Chromodynamics</i> concentrates, however, not on the phenomenological aspect of QCD; books with comprehensive coverage of phenomenological issues have been written. What the reader will find in this book is a profound discussion on the theoretical foundations of QCD with emphasis on the nonperturbative formulation of the theory: What is gauge symmetry on the classical and on the quantum level? What is the path integral in field theory? How to define the pa

• Sommario/riassunto: There is constant pressure on hospitals to improve health care delivery and increase cost effectiveness. New initiatives are the order of the day in the dramatically different health care systems of the United States and Great Britain. Often, as we know all too well, these efforts are not successful. In The Challenge to Change, Rebecca Kolins Givan analyzes the successes and failures of efforts to improve hospitals and explains what factors make it likely that the implementation of reforms will be ; rewarded by positive transformation in a particular institution's day-to-day operation. Givan's in-depth qualitative case studies of both top-down initiatives and changes first suggested by staff on the front lines of care point clearly to the importance of all hospital workers in effecting change and even influencing national policy.Givan illuminates the critical role of workers, managers, and unions in enabling or constraining changes in policies and procedures and ensuring their implementation. Givan spotlights an Anglo-American model of hospital care and work organization, even while these countries retain their differences in access and payment. Entrenched professional roles, hierarchical workplace organization, and the sometimes-detached view of policymakers all shape the prospects for change in hospitals. Givan provides important examples of how the dedication and imagination of the people who work in hospitals can make all the difference when it comes to providing quality health care even in a challenging economic environment.
