Age Factors in Biometric Processing

Michael Fairhurst

The Institution of Engineering and Technology, 2013

As biometrics-based identification and identity authentication become increasingly widespread in their deployment, it becomes correspondingly important to consider more carefully issues relating to reliability, usability and inclusion. One factor which is particularly important in this context is that of the relationship between the nature of the measurements extracted from a particular biometric modality and the age of the sample donor, and the effect which age has on physiological and behavioural characteristics invoked in a biometric transaction.

Grandmotherhood

The Evolutionary Significance of the Second Half of Female Life

Voland, Eckart

Rutgers University Press, 2014

By the year 2030, the average life expectancy of women in industrialized countries could reach ninety—exceeding that of men by about ten years. At the present time, postmenopausal women represent more than fifteen percent of the world’s population and this figure is likely to grow.

From an evolutionary perspective, these demographic numbers pose some intriguing questions. Darwinian theory holds that a successful life is measured in terms of reproduction. How is it, then, that a woman’s lifespan can greatly exceed her childbearing and childrearing years? Is this phenomenon simply a byproduct of improved standards of living, or do older women—grandmothers in particular—play a measurable role in increasing their family members’ biological success?

Until now, these questions have not been examined in a thorough and comprehensive manner. Bringing togethertheoretical and empirical work byinternationally recognized scholars in anthropology, psychology, ethnography, and the social sciences, Grandmotherhood explores the evolutionary purpose and possibilities of female post-generative life. Students and scholars of human evolution, anthropology, and even gerontology will look to this volume as a major contribution to the current literature in evolutionary studies.

How Healthy Are We?

A National Study of Well-Being at Midlife

Edited by Orville Gilbert Brim, Carol D. Ryff, and Ronald C. Kessler

University of Chicago Press, 2003

Childhood, adolescence, even the "twilight years" have been extensively researched and documented. But the vast terrain known as midlife—the longest segment of the life course—has remained uncharted. How physically and psychologically healthy are Americans at midlife? And why do some experience greater well-being than others?

The MacArthur Foundation addressed these questions head-on by funding a landmark study known as "Midlife in the U.S.," or MIDUS. For the first time in a single study, researchers were able to integrate epidemiological, sociological, and psychological assessments, as well as innovative new measures to evaluate how work and family life influence each other.

How Healthy Are We? presents the key findings from the survey in three sections: physical health, quality of life and psychological well-being, and the contexts (family, work) of the midlife. The topics covered by almost forty scholars in a wide variety of fields are vast, including everything from how health and well-being vary with socioeconomic standing, gender, race, or region of the country to how middle-aged people differ from younger or older adults in their emotional experience and quality of life. This health—the study measures not only health-the absence of illness—but also reports on the presence of wellness in middle-aged Americans.

The culmination of a decade and a half of research by leading scholars, How Healthy Are We? will dramatically alter the way we think about health in middle age and the factors that influence it. Researchers, policymakers, and others concerned about the quality of midlife in contemporary America will welcome its insights.

* Having a good life means having good relationships with others to almost 70% of those surveyed. Less than 40% mentioned their careers.

* Reports of disruptive daily stressors vary by age, with young adults and those in midlife experiencing more than those in later adulthood.

* Men have higher assessments of their physical and mental health than woman until the age of 60.

Profiles in Cognitive Aging

Douglas Powell

Harvard University Press, 1994

After the age of 40, we may notice occasional lapses—a forgotten phone number, a friend's name, or a word that was right on the tip of our tongue. By 60, we may find ourselves wondering who called this morning, why we came into the kitchen, where we parked the car. In an aging nation, where one citizen in seven will be 65 when the next century arrives, these little difficulties raise a larger question: What precisely happens to our thinking as we grow older? What is normal, what is not, and how are we to know the signs?

Douglas Powell offers a comprehensive account of cognitive aging, of how our mental functions change as we mature. Defining patterns of normal decline, as well as severe forms of cognitive impairment, this book will help us understand and address the needs of an aging population. Powell integrates the latest literature on aging with the findings of his recent study of 1,000 physicians and 600 other subjects ranging in age from 25 to 92. His work reveals patterns of cognitive aging throughout the life cycle, particularly the way in which variability among individuals outpaces the decline of overall ability. Tackling an issue of growing interest in the field of gerontology, he notes the effect of certain factors such as gender, diet, health, and physical and mental exercise on changes in cognitive functioning over time.

Along with the criteria for mild cognitive impairment and normal cognitive aging, this book addresses the question of optimal cognitive aging, identifying its characteristics and searching out their implications for the maintenance of intellectual abilities in the post-retirement years.

Women among Women

Anthropological Perspectives on Female Age Hierarchies

Edited by Jeanette Dickerson-Putman and Judith K. Brown: Foreword by Nancy Foner

University of Illinois Press, 1994

Are the prerogatives of age universal? This first-ever anthropological exploration of relationships between older and younger women suggests that this may be the case. Cross-cultural in nature, the volume looks at relationships between women of different age groups in a village in Taiwan, a town in central Sudan, a rural setting in western Kenya, an Andean peasant community, a horticultural village in Melanesia, and an Aboriginal community in Australia. Adding an interspecies perspective is a study of two age groups of Japanese Macaques. Included is an ethnographic bibliography that lists books with a wealth of information on women in sixty societies. The volume will appeal not only to anthropologists but also to readers interested in women's issues, gender studies, life course studies, gerontology, and intergenerational relations.
