Sommario/riassunto |
|
This book presents a modern view of anomalies in quantum field theories. It is divided into six parts. The first part is preparatory covering an introduction to fermions, a description of the classical symmetries, and a short introduction to conformal symmetry. The second part of the book is devoted to the relation between anomalies |

and cohomology. The third part deals with perturbative methods to compute gauge, diffeomorphism and trace anomalies. In the fourth part the same anomalies are calculated with non-perturbative heat-kernel-like methods. Part five is devoted to the family's index theorem and its application to chiral anomalies, and to the differential characters and their applications to global anomalies. Part six is devoted to special topics including a complete calculation of trace and diffeomorphism anomalies of a Dirac fermion in a MAT background in two dimensions, Wess-Zumino terms in field theories, sigma models, their local and global anomalies and their cancelation, and finally the analysis of the worldsheet, sigma model, and target space anomalies of string and superstring theories. The book is targeted to researchers and graduate students. |

Sommario/riassunto |
|
Informed by the social-ecological framework, this book focuses on the development of Home and Community Based Services (HCBS) in urban China. Bringing a timely discussion around HCBS development in Shanghai, it presents an interplay of formal caregiving relationships, evolving caregiving culture, and the trajectory of long-term care in China. Drawing on surveys, in-depth interviews, and government archives, this book explores the emergence of one of the most developed HCBS programs in Shanghai, its development over the past decade, its administration and services, resource allocation, staff |

members' work experiences, older adults' service experiences, as well as service evaluation and improvements. Offering fresh insight into new forms of caregiving in community settings, and shaping a new discourse on caregiving policy, this book is a key read for both students and practitioners in the fields of long-term care, gerontology, geriatrics, health care, and health policy. |
