Download or read book The Descent of Human Sex Ratio at Birth written by Éric Brian and published by Springer Science & Business Media. This book was released on 2007-07-24 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an attempt to renew our links with the oldest traditions of scholarly thinking, but is also a well-tempered reflection on today’s work in objectivization. After a deconstruction of the past and present conditions of scientific understanding of human sex-ratio at birth, the authors propose a reconstruction of the dynamics of the phenomenon based on stochastics. Appendices provide information on the first expression of sex ratio trends, as well as a comparison of Darwin’s treatments of the subject.
Book Synopsis Exploring the Biological Contributions to Human Health by : Institute of Medicine
Download or read book Exploring the Biological Contributions to Human Health written by Institute of Medicine and published by National Academies Press. This book was released on 2001-07-02 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Choosing Sexes by : Kristen J. Navara
Download or read book Choosing Sexes written by Kristen J. Navara and published by Springer. This book was released on 2018-02-01 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is extensive evidence that vertebrates of all classes have the ability to control the sexes of the offspring they produce. Despite dramatic differences in the mechanisms by which different taxa determine the initial sex of offspring, each group has found its own way of adjusting offspring sex ratios in response to social and environmental cues. For example, stress is a well-known modulator of offspring sex in members of all groups studied to date. Food availability, and limitation in particular, is another common cue that stimulates biases in offspring sex ratios in a wide variety of species. Offspring sex can be adjusted at the primary level, which occurs prior to conception, or at the secondary level, during embryonic development. While the mechanistic pathways that ultimately result in sex ratio biases and the developmental time-points sensitive to those mechanisms likely differ among taxa, the key involvement of steroid hormones in the process of sex ratio adjustment appears to be pervasive throughout. This book reviews the systems of sex determination at play in different vertebrate groups, summarizes the evidence that members of all vertebrate taxa can facultatively adjust offspring sex, and discusses when and how these adjustments can take place.
Book Synopsis The Theory of Sex Allocation. (MPB-18), Volume 18 by : Eric L. Charnov
Download or read book The Theory of Sex Allocation. (MPB-18), Volume 18 written by Eric L. Charnov and published by Princeton University Press. This book was released on 2020-03-31 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first comprehensive treatment of sex allocation from the standpoint of modern evolutionary theory. It shows how the determination of sex ratio, resource allocation to sperm versus egg within simultaneous hermaphroditism, and the evolution of sex reversal can he explained as examples of a single process. The genetical theory, developed mostly with graphical arguments, also specifies when hermaphroditism and dioecy are themselves evolutionary stable. The work balances theory with field and laboratory research, providing critical tests of the theory by empirical studies of sex ratio in parasitoid wasps and mites, sex reversal in shrimp and coral reef fish, and allocation of resources to pollen versus seeds in higher plants. In addition, the author oilers an encyclopedic review of the field and laboratory work of other scientists, reviews many as yet untested hypotheses in sex allocation, and points toward numerous plant and animal systems that hold promise for future tests.
Book Synopsis Theoretical Studies on Sex Ratio Evolution. (MPB-22), Volume 22 by : Samuel Karlin
Download or read book Theoretical Studies on Sex Ratio Evolution. (MPB-22), Volume 22 written by Samuel Karlin and published by Princeton University Press. This book was released on 2020-03-31 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with a key area of population genetics: the ratio of the sexes in a population, or the allocation of resources to male versus female reproductive function. Samuel Karlin and Sabin Lessard establish the formal theoretical aspects of the evolution of sex ratio within the constraints of genetic mechanisms of sex determination. Their results generalize and unify existing work on the topic, strengthening previous conceptions in some cases and, in other instances, offering new directions of research. There are two main approaches to understanding the causes and effects of sex ratio. One approach focuses on the optimization and adaptive functions of sex allocation, while the other emphasizes the consequences of genetic sex determination mechanisms. In discussing the utility of these two approaches, Professors Karlin and Lessard examine the principal sex-determining mechanisms and facts involved in sex ratio representations, the various genetic and environmental factors that contribute to adaptive sex expression, and the evolution of sex determining systems and controls. From a population genetic perspective, the authors derive evolutionary properties in support of the high incidence of 1:1 sex ratio in natural populations and investigate the conditions that can explain the occurrence of biased sex ratio.

Book Synopsis Sex Differences in Social Behavior by : Alice H. Eagly
Download or read book Sex Differences in Social Behavior written by Alice H. Eagly and published by Psychology Press. This book was released on 2013-05-13 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Joseph Smith’s Polygamy, Volume 3: Theology by : Brian C. Hales
Download or read book Joseph Smith’s Polygamy, Volume 3: Theology written by Brian C. Hales and published by Greg Kofford Books. This book was released on 2013-02-26 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: Americans of Joseph Smith’s day, steeped in the stories and prophecies of the King James Bible, certainly knew about plural marriage; but it was a curiosity relegated to the misty past of patriarchs Abraham and Jacob, who never gave reasons for their polygamy. It was long abandoned, Christians understood, by the time Jesus set forth the dominating law of the New Testament. But how did Joseph Smith understand it? Where did it fit in the “restitution of all things” (Acts 3:21) predicted in the New Testament? What part did it play in the global ideology declared by this modern prophet who produced new scripture, new revelation, and new theology? During Joseph Smith’s lifetime, polygamy was taught and practiced in intense secrecy, with the result that he never fully explained its doctrinal underpinnings or systematized its practice. As a result, reconstructing Joseph Smith’s theology of plurality is a task that has seldom been undertaken. Most theological examinations have either focused on its development during Brigham Young’s Utah period, with its need to resist increasing federal legislative and judicial pressures, or the efforts of twentieth-century and contemporary “fundamentalists” who continue to marry a plurality of wives. Volume 3 of this three-volume work builds on the carefully reconstructed history of the development of Mormon polygamy during Joseph Smith’s lifetime, then assembles the doctrinal principles from his recorded addresses, the diary entries of those closely associated with him, and his broader teachings on the related topics of obedience to God’s will, marriage and family relations, and the mechanics of eternal progression, salvation, and exaltation. The revelation he dictated in July 1843 that authorized the practice of eternal and plural marriage receives unprecedented examination and careful interpretation that illuminate this significant document and its underlying doctrines. Attempts to explain the history of Joseph Smith’s polygamy without comprehending the theological principles undergirding its practice will always be incomplete and skewed. This volume, which takes those principles and evidences with the utmost seriousness, has produced the most important explanation of “why” this ancient practice reemerged among the Latter-day Saints on the shores of the Mississippi in the early 1840s.
Book Synopsis Child Abuse and Neglect by : Jane B. Lancaster
Download or read book Child Abuse and Neglect written by Jane B. Lancaster and published by Routledge. This book was released on 2017-09-04 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Child Abuse and Neglect is the third volume sponsored by the Social Science Research Council. The goals of these volumes include the development of a biosocial perspective and its application to the interface between biological and social phenomena in order to advance the understanding of human behavior.Child Abuse and Neglect applies the biosocial perspective to child maltreatment and maladaptation in parent-child relations. The biosocial perspective is particularly appropriate for investigating parent behavior since the family is the universal social institution in which children are born and reared, in which cultural traditions and values are transmitted, and in which individuals fulfill their biological potential for reproduction, growth, and development. The volume examines biological substrates and social and environmental contexts as determinants of parent behavior. By identifying areas in which contemporary human parent behaviors conform with and depart from evolutionary and historical patterns and assessing the overall costs and benefits, it permits their objective assessment in terms of modern circumstances. In analyzing evolutionary and historical variations in parent behavior and assessing their costs and benefits, the book makes possible an objective assessment of contemporary variations. Its analysis of the occurrence of child abuse in past history and in other cultures and species advances our ability to predict the probability of child abuse and neglect in various social and ecological contexts.

Book Synopsis Probability and Social Science by : Daniel Courgeau
Download or read book Probability and Social Science written by Daniel Courgeau and published by Springer Science & Business Media. This book was released on 2012-02-23 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work examines in depth the methodological relationships that probability and statistics have maintained with the social sciences from their emergence. It covers both the history of thought and current methods. First it examines in detail the history of the different paradigms and axioms for probability, from their emergence in the seventeenth century up to the most recent developments of the three major concepts: objective, subjective and logicist probability. It shows the statistical inference they permit, different applications to social sciences and the main problems they encounter. On the other side, from social sciences—particularly population sciences—to probability, it shows the different uses they made of probabilistic concepts during their history, from the seventeenth century, according to their paradigms: cross-sectional, longitudinal, hierarchical, contextual and multilevel approaches. While the ties may have seemed loose at times, they have more often been very close: some advances in probability were driven by the search for answers to questions raised by the social sciences; conversely, the latter have made progress thanks to advances in probability. This dual approach sheds new light on the historical development of the social sciences and probability, and on the enduring relevance of their links. It permits also to solve a number of methodological problems encountered all along their history.
Book Synopsis An Anthropology of Biomedicine by : Margaret M. Lock
Download or read book An Anthropology of Biomedicine written by Margaret M. Lock and published by John Wiley & Sons. This book was released on 2018-01-09 with total page 563 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this fully revised and updated second edition of An Anthropology of Biomedicine, authors Lock and Nguyen introduce biomedicine from an anthropological perspective, exploring the entanglement of material bodies with history, environment, culture, and politics. Drawing on historical and ethnographic work, the book critiques the assumption made by the biological sciences of a universal human body that can be uniformly standardized. It focuses on the ways in which the application of biomedical technologies brings about radical changes to societies at large based on socioeconomic inequalities and ethical disputes, and develops and integrates the theory that the human body in health and illness is not an ontological given but a moveable, malleable entity. This second edition includes new chapters on: microbiology and the microbiome; global health; and, the self as a socio-technical system. In addition, all chapters have been comprehensively revised to take account of developments from within this fast-paced field, in the intervening years between publications. References and figures have also been updated throughout. This highly-regarded and award-winning textbook (Winner of the 2010 Prose Award for Archaeology and Anthropology) retains the character and features of the previous edition. Its coverage remains broad, including discussion of: biomedical technologies in practice; anthropologies of medicine; biology and human experiments; infertility and assisted reproduction; genomics, epigenomics, and uncertain futures; and molecularizing racial difference, ensuring it remains the essential text for students of anthropology, medical anthropology as well as public and global health.
