Quantification of and Gender Differences in Human Loudness Adaptation


Book Description

Introduction. Previous studies report gender differences in the auditory system; however, none reports gender differences in auditory adaptation, the decrease in perceived loudness to protracted auditory stimulation. Experiments. We applied a 6-min tone to a participant's adapting ear. Each minute on the minute, participants adjusted the intensity of an iso-frequency tone in the contralateral control ear until both tones sounded equally loud. We calculated adaptation as the intensity difference between a reference level and that registered at later time points. Results. At each time pint, the magnitude of femaile adaptation was greater than that of males. Adaptation was found to oscillate with time. Model. We created a model of loudness for each ear, and used it to obtain values of a psychophysical parameter. Hypothesis. The magnitude of loudness adaptation will differ between genders when we administer pure tones of constant intensity and frequency to participants.




Hearing Loss


Book Description

Millions of Americans experience some degree of hearing loss. The Social Security Administration (SSA) operates programs that provide cash disability benefits to people with permanent impairments like hearing loss, if they can show that their impairments meet stringent SSA criteria and their earnings are below an SSA threshold. The National Research Council convened an expert committee at the request of the SSA to study the issues related to disability determination for people with hearing loss. This volume is the product of that study. Hearing Loss: Determining Eligibility for Social Security Benefits reviews current knowledge about hearing loss and its measurement and treatment, and provides an evaluation of the strengths and weaknesses of the current processes and criteria. It recommends changes to strengthen the disability determination process and ensure its reliability and fairness. The book addresses criteria for selection of pure tone and speech tests, guidelines for test administration, testing of hearing in noise, special issues related to testing children, and the difficulty of predicting work capacity from clinical hearing test results. It should be useful to audiologists, otolaryngologists, disability advocates, and others who are concerned with people who have hearing loss.




Exploring the Biological Contributions to Human Health


Book Description

It's obvious why only men develop prostate cancer and why only women get ovarian cancer. But it is not obvious why women are more likely to recover language ability after a stroke than men or why women are more apt to develop autoimmune diseases such as lupus. Sex differences in health throughout the lifespan have been documented. Exploring the Biological Contributions to Human Health begins to snap the pieces of the puzzle into place so that this knowledge can be used to improve health for both sexes. From behavior and cognition to metabolism and response to chemicals and infectious organisms, this book explores the health impact of sex (being male or female, according to reproductive organs and chromosomes) and gender (one's sense of self as male or female in society). Exploring the Biological Contributions to Human Health discusses basic biochemical differences in the cells of males and females and health variability between the sexes from conception throughout life. The book identifies key research needs and opportunities and addresses barriers to research. Exploring the Biological Contributions to Human Health will be important to health policy makers, basic, applied, and clinical researchers, educators, providers, and journalists-while being very accessible to interested lay readers.




The Oxford Handbook of Women and the Economy


Book Description

The transformation of women's lives over the past century is among the most significant and far-reaching of social and economic phenomena, affecting not only women but also their partners, children, and indeed nearly every person on the planet. In developed and developing countries alike, women are acquiring more education, marrying later, having fewer children, and spending a far greater amount of their adult lives in the labor force. Yet, because women remain the primary caregivers of children, issues such as work-life balance and the glass ceiling have given rise to critical policy discussions in the developed world. In developing countries, many women lack access to reproductive technology and are often relegated to jobs in the informal sector, where pay is variable and job security is weak. Considerable occupational segregation and stubborn gender pay gaps persist around the world. The Oxford Handbook of Women and the Economy is the first comprehensive collection of scholarly essays to address these issues using the powerful framework of economics. Each chapter, written by an acknowledged expert or team of experts, reviews the key trends, surveys the relevant economic theory, and summarizes and critiques the empirical research literature. By providing a clear-eyed view of what we know, what we do not know, and what the critical unanswered questions are, this Handbook provides an invaluable and wide-ranging examination of the many changes that have occurred in women's economic lives.

Urban Evolutionary Biology


Book Description

Urban Evolutionary Biology fills an important knowledge gap on wild organismal evolution in the urban environment, whilst offering a novel exploration of the fast-growing new field of evolutionary research. The growing rate of urbanization and the maturation of urban study systems worldwide means interest in the urban environment as an agent of evolutionary change is rapidly increasing. We are presently witnessing the emergence of a new field of research in evolutionary biology. Despite its rapid global expansion, the urban environment has until now been a largely neglected study site among evolutionary biologists. With its conspicuously altered ecological dynamics, it stands in stark contrast to the natural environments traditionally used as cornerstones for evolutionary ecology research. Urbanization can offer a great range of new opportunities to test for rapid evolutionary processes as a consequence of human activity, both because of replicate contexts for hypothesis testing, but also because cities are characterized by an array of easily quantifiable environmental axes of variation and thus testable agents of selection. Thanks to a wide possible breadth of inference (in terms of taxa) that may be studied, and a great variety of analytical methods, urban evolution has the potential to stand at a fascinating multi-disciplinary crossroad, enriching the field of evolutionary biology with emergent yet incredibly potent new research themes where the urban habitat is key. Urban Evolutionary Biology is an advanced textbook suitable for graduate level students as well as professional researchers studying the genetics, evolutionary biology, and ecology of urban environments. It is also highly relevant to urban ecologists and urban wildlife practitioners.




The World Color Survey


Book Description

The 1969 publication of Brent Berlin and Paul Kay's Basic Color Terms proved explosive and controversial. Contrary to the then-popular doctrine of random language variation, Berlin and Kay's multilingual study of color nomenclature indicated a cross-cultural and almost universal pattern in the selection of colors that received abstract names in each language. The ensuing debate helped reform the views of anthropologists, linguists, and psychologists alike. After four decades in print, Basic Color Terms now has a sequel: in this book, the authors authoritatively extend the original survey, studying 110 additional unwritten languages in detail and in situ. The results are presented with charts showing the overall palette of color terms within each language as well as the levels of agreement among speakers.




Sex Differences in Social Behavior


Book Description

In presenting an innovative theory of sex differences in the social context, this volume applies social-role theory and meta-analytic techniques to research in aggression, social influence, helping, nonverbal, and group behavior. Eagly's findings show that gender stereotypic behavior results from different male and female role expectations, and that the disparity between these gender stereotypes and actual sex differences is not as great as is often believed.




Quantifying Quality Aspects of Multimodal Interactive Systems


Book Description

This book systematically addresses the quantification of quality aspects of multimodal interactive systems. The conceptual structure is based on a schematic view on human-computer interaction where the user interacts with the system and perceives it via input and output interfaces. Thus, aspects of multimodal interaction are analyzed first, followed by a discussion of the evaluation of output and input and concluding with a view on the evaluation of a complete system.




The Promise of Adolescence


Book Description

Adolescenceâ€"beginning with the onset of puberty and ending in the mid-20sâ€"is a critical period of development during which key areas of the brain mature and develop. These changes in brain structure, function, and connectivity mark adolescence as a period of opportunity to discover new vistas, to form relationships with peers and adults, and to explore one's developing identity. It is also a period of resilience that can ameliorate childhood setbacks and set the stage for a thriving trajectory over the life course. Because adolescents comprise nearly one-fourth of the entire U.S. population, the nation needs policies and practices that will better leverage these developmental opportunities to harness the promise of adolescenceâ€"rather than focusing myopically on containing its risks. This report examines the neurobiological and socio-behavioral science of adolescent development and outlines how this knowledge can be applied, both to promote adolescent well-being, resilience, and development, and to rectify structural barriers and inequalities in opportunity, enabling all adolescents to flourish.
