Gerontology in the Era of the Third Age


Book Description

The "third age" is described as the period in the life course that occurs after retirement but prior to the onset of disability, revealing a period in which individuals have the capacity to remain actively engaged. This book serves as a comprehensive discussion about how the emergence of the third age has changed the way we think about and examine traditional frameworks regarding aging issues and the life course. It introduces the discussion of the unique challenges and opportunities that older adults face while moving through this early phase of later life, proposing new frameworks, concepts, and methods to re-examine later life in the context of the era of the third age. This book proposes new ways of thinking about how we conceptualize the life course, think about the role of the welfare state in the lives of older people, negotiate social roles in later life, make meaning of our lives as we age, and cultivate relationships with others during later life. It brings together theoretical concepts and frameworks, methodological advances, and emerging themes and controversies that are redefining gerontology in the era of the Third Age. Highlighting important issues that warrant further exploration and discussion, this book advances our understanding of the Third Age and focuses attention on critical issues that should be addressed in future Third Age research and scholarly development. Key Features: Includes up-to-date description and analysis of the third age as a concept, life phase, and social status Addresses multiple perspectives to illustrate the impact of the third age on the way we examine later life Uses disciplinary perspectives such as social policy, demography, gerontology, sociology, social work, anthropology, and social psychology Examines mechanisms that stratify the older population in the context of the third age




Differential Rotation in Sun-like Stars from Surface Variability and Asteroseismology


Book Description

In his PhD dissertation Martin Bo Nielsen performs observational studies of rotation in stars like the Sun. The interior rotation in stars is thought to be one of the driving mechanisms of stellar magnetic activity, but until now this mechanism was unconstrained by observational data. NASA’s Kepler space mission provides high-precision observations of Sun-like stars which allow rotation to be inferred using two independent methods: asteroseismology measures the rotation of the stellar interior, while the brightness variability caused by features on the stellar surface trace the rotation of its outermost layers. By combining these two techniques Martin Bo Nielsen was able to place upper limits on the variation of rotation with depth in five Sun-like stars. These results suggest that the interior of other Sun-like stars also rotate in much the same way as our own Sun.
