How long can humans live? This open access book documents, verifies and brings to life the advance of the frontier of human survival. It carefully validates data on supercentenarians, aged 110+, and semi-supercentenarians, aged 105-109, stored in the International Database on Longevity (IDL). The chapters in this book contribute substantial advances in rigorously checked facts about exceptional lifespans and in the application of state-of-the-art analytical strategies to understand trends and patterns in these rare lifespans. The book includes detailed accounts of extreme long-livers and how their long lifespans were documented, as well as reports on the causes of death at the oldest ages. Its key finding, based on the analysis of 1,219 validated supercentenarians, is that the annual probability of death is constant at 50% after age 110. In contrast to previous assertions about a ceiling on the human lifespan, evidence presented in this book suggests that lifespan records in specific countries and globally will be broken again and again as more people survive to become supercentenarians. ​

Offers readers a fresh view of the varied and rich areas of lifespan communication research. In this book, top scholars across several disciplines have contributed to chapters within their domains of expertise, highlighting significant horizons that will guide researchers for years to come. The Handbook of Lifespan Communication is the foundational scholarly text that offers readers a state of the art view of the varied and rich areas of lifespan communication research. The fundamental assumptions of lifespan communication are that the very nature of human communication is developmental, and, to truly understand communication, change across time must be incorporated into existing theory and research. Beginning with chapters on lifespan communication theory and methodologies, chapters are then organized into the various phases of life: early childhood, adolescence, emerging adulthood, middle adulthood, and older adulthood. Top scholars across several disciplines have contributed to chapters within their domains of expertise, highlighting significant horizons that will guide researchers for years to come.

"This innovative collection examines key questions on language diversity and multilingualism running through contemporary debates in psycholinguistics and sociolinguistics. Reinforcing interdisciplinary conversations on these themes, each chapter is co-authored by two different researchers, often those who have not written together before. The combined effect is a volume showcasing unique and dynamic perspectives on such topics as multilingualism across the lifespan, bilingual acquisition, family language policy, language and aging, language shift, language and identity, and multilingualism and language impairment. The book builds on Elizabeth Lanza's pioneering work on multilingualism across the lifespan, bringing together cutting-edge research exploring multilingualism as an evolving phenomenon at landmarks in individuals', families' and communities' lives. Taken together, the book offers a rich portrait of the different facets of multilingualism as lived reality for individuals, families, and communities. This groundbreaking volume will be of particular interest to students and scholars in multilingualism, applied linguistics, sociolinguistics, and psycholinguistics"--

As demographic changes impact the workplace, governments, organizations and workers are looking for ways to sustain optimal working lives at higher ages. Workplace flexibility has been introduced as a potential way workers can have more satisfying working lives until their retirement ages. This paper presents a critical review of the literature on workplace flexibility across the lifespan. It discusses how flexibility has been conceptualized across different disciplines, and postulates a definition that captures the joint roles of employer and employee in negotiating workplace flexibility that contributes to both employee and organization benefits. Moreover, it reviews how flexibility has been theorized and investigated in relation to older workers. The paper ends with a future research agenda for advancing understanding of how workplace flexibility may enhance working experiences of older workers, and in particular focuses on the critical investigation of uses of flexibility in relation to older workers.

Language Development over the Lifespan, compiled by Kees de Bot and Robert W. Schrauf, is a collection of articles that explore language development—both language acquisition and language attrition—from a lifespan perspective. This volume of articles was, first of all, intended as a reference resource for research on language development and the aging process and as a text for MA courses in applied linguistics/bilingualism programs. More importantly, this book establishes a new and exciting perspective on language acquisition by considering developmental language phenomena, that is, "developmental" changes in language that occur over the span of a lifetime. This volume thus opens up new windows to research language acquisition from a developmental perspective. Language development becomes a function of the interaction of timescales both within the lifespan of the individual and at a larger "biocultural" (i.e., historical) level of language development. Historical events like the adoption of an official language by a government, for example, generate changes in language use at a macro-level, which in turn produce "cohort effects" that affect language development within the individual. A key concept to this lifespan perspective is that language is a dynamic system involving multiple components and subsystems. This book provides a comprehensive overview of the impact of cognitive and psychological factors, as well as social and cultural factors like the role of life events in the dynamic development of language.

Middle adulthood is a critical period of the life course. How we develop in middle age-the central period of our lives-can influence how well we cope in our later years. Middle Adulthood: A Lifespan Perspective explores these issues by bringing together a distinguished group of international contributors associated with a range of prestigious longitudinal studies.  

Personal Relationships Across the Lifespan presents a comprehensive and up-to-date account of the role of personal relationships in people's lives.Highlighting areas of special significance and research interest at each major life-stage, Patricia Noller, Judith A. Feeney and Candida Peterson, examine how close relationships develop over time and influence individual adjustment. They explore a wide range of relationships, including some that are often neglected, such as those with siblings, adult children and elderly parents. They also look at alternative family forms, such as sing
