This book provides an account of modern aspects relating far infrared radiation to properties of solids; it encompasses both theoretical and experimental considerations. Written at the gradu- ate level, it attempts a threefold purpose; an indication of the breadth of the subject, an in-depth examination of important areas, and reference material to complement a text for a course. The treatment and organization of material here is compatible with a preceding volume of this series on "Optical Properties of Solids." Chapters 1-6 present material concerned principally with experimental...

This book is an account of the manner in which the optical phenomena observed from solids relate to their fundamental properties. Written at the graduate level, it attempts a threefold purpose: an indication of the breadth of the subject, an in-depth examination of important areas, and a text for a two-semester course. The first two chapters present introductory theory as a foundation for subsequent reading. The following ten chapters broadly concern electronic properties associated with semiconductors ranging from narrow to wide energy gap materials. Lattice properties are examined in the...

This open access book introduces the human development model to define disability and map its links with health and wellbeing, based on Sen's capability approach. The author uses panel survey data with internationally comparable questions on disability for Ethiopia, Malawi, Tanzania and Uganda. It presents evidence on the prevalence of disability and its strong and consistent association with multidimensional poverty, mortality, economic insecurity and deprivations in education, morbidity and employment. It shows that disability needs to be considered from multiple angles including aging,...
