This provocative, intellectually charged treatise serves as a concise introduction to emancipatory gerontology, examining multiple dimensions of persistent and hotly debated topics around aging, the life course, the roles of power, politics and partisanship, culture, economics, and communications. Critical perspectives are presented as definitions for reader understanding, with links to concepts of identity, knowledge construction, social networks, social movements, and inequalities. With today's intensifying concentration of wealth and corporatization, precarity is the fate for growing numbers of the world's population. Intersectionality as an analytic concept offers a new appreciation of how social advantage and disadvantage accumulate, and how constructions of race, ethnicity, class, ability, and gender influence aging. The book's entries offer a bibliographic compendium, crediting the salience of early pioneering theorists and locating these within the cutting-edge of research (social, behavioral, policy, and gene-environment sciences) that currently advances our understandings of human development, trauma, and resilience. Accompanying these foundations are theories of resistance for advancing human rights and the dignity of marginalized populations.
