Localization and Orientation in Biology and Engineering


Book Description

The German Society of Cybernetics organizes international conferences on selected interdisciplinary topics in regular 3-year intervals. The aim of these meetings is to bring together scientists who work in quite different disciplines, but are confronted with related problems and use the same or similar approaches. The topic of the 1983 conference which was held on March 23-25 at the University of Tiibingen came from a typical field of research in which engineers, biologists, and phYSicists share a common interest. We do not want to discuss here in detail the common principles which are used by nature and by engineers to solve the problems associated with localization and orientation, since the reader will find enough examples in this volume. The question, however, whether the participants of such meetings can really profit from each other, deserves some further consid eration. First, there is the difficulty of finding a common language. This still seems to be a problem, although in some fields the language of engineers and biologists has become very similar over the years, an impression we also gained during the conference. Most of the authors made a great ef fort to use a vocabulary which is understandable to people outside their own field of research, but, admittedly, not all succeeded.




What Causes Sexual Orientation? Genetics, Biology, Psychology


Book Description

The debate over "nature versus nature" continues over the causes of homosexuality. Is there a gay gene? Is there something about the way a child is raised that can "turn" her gay? Or is being gay simply a "choice"? Taking a look at the major genetic, biological, and psychological theories of the origins of homosexuality, this book asks questions about gender, gender identity, and sexual orientation that are at the center of gay people's sense of identity and their struggle for civil rights and acceptance by society. While for centuries homosexuality was considered a mental illness, a moral failure, or a biological disorder, gay people in the twenty-first century have the evidence of scientific research and their authentic experiences of happy and fulfilling lives to support the pride and sense of community that is their rightful place in the modern world.




Nature's Choice


Book Description

The true role of biology in determining sexual orientation is an oft-debated issue in both the popular media and scientific communities, and evaluating the literature on the topic can be daunting. Nature’s Choice: What Science Reveals About the Biological Origins of Sexual Orientation offers both a comprehensive review of the scientific literature and a fresh perspective on this complex and politically charged subject. Respected researcher, speaker, and author Dr. Cheryl Weill offers readers of all backgrounds an enlightening analysis of findings from over twenty years of research on the factor of biology in the determination of sexual orientation. Nature’s Choice: What Science Reveals About the Biological Origins of Sexual Orientation brilliantly distills complicated studies and research findings dealing with brain anatomy, genetics, sex-typical behavior in children, auditory, startle reflex, and many other areas. Spanning a wide range of important topics including human sexual development and the effects of hormones, Ellis and Ames’ Gestational Neurohormonal Theory, the ins, outs, and implications of how scientific research is funded, and model of the role of testosterone in determining human sexuality, Nature’s Choice: What Science Reveals About the Biological Origins of Sexual Orientation is an exciting book to educate and inspire readers from scientific and non-scientific backgrounds equally.




Sexual Orientation in Child and Adolescent Health Care


Book Description

Sexual Orientation in Child and Adolescent Health Care serves as a resource for child health care professionals including pediatricians, family physicians, nurses, pediatric psychologists, child and adolescent psychiatrists, and social workers. The issues of sexuality and sexual orientation now generate great interest among those who treat children. This volume describes the effects of stigmatization on non-heterosexual physicians, patients, and students, and discusses a variety of clinically relevant topics including the development of sexual orientations, children of gay or lesbian parents, young children with gender atypical behavior, and the healthcare needs of gay and lesbian adolescents. The last two chapters describe methods for improvement in medical education and medical care, and provide extensive resources available to professionals and consumers.




Ethics, Sexual Orientation, and Choices about Children


Book Description

A critical review of the debate over the still-hypothetical possibility of prenatal intervention by parents to select the sexual orientation of their children. Parents routinely turn to prenatal testing to screen for genetic or chromosomal disorders or to learn their child's sex. What if they could use similar prenatal interventions to learn (or change) their child's sexual orientation? Bioethicists have debated the moral implications of this still-hypothetical possibility for several decades. Some commentators fear that any scientific efforts to understand the origins of homosexuality could mean the end of gay and lesbian people, if parents shy away from having homosexual children. Others defend parents' rights to choose the traits of their children in general and see no reason to treat sexual orientation differently. In this book, Timothy Murphy traces the controversy over prenatal selection of sexual orientation, offering a critical review of the literature and presenting his own argument in favor of parents' reproductive liberty. Arguing against commentators who want to restrict the scientific study of sexual orientation or technologies that emerge from that study, Murphy proposes a defense of parents' right to choose. This, he argues, is the only view that helps protect children from hurtful family environments, that is consistent with the increasing powers of prenatal interventions, and that respects human futures as something other than accidents of the genetic lottery.

Advances in Cell Biology


Book Description

Advances in Cell Biology has been initiated as a continuing, multi-volume series to report on the progress of a wide spectrum of problems of cell structure and cell function. Jn arranging these volumes individual contributors are asked not only to review the major new information, but especially to present the state of a given problem or area by discussing the current central issues, speculations, concepts, hypotheses, and technical problems. We intend, in addition, that these volumes will not be concerned with comprehensive reviews of the recent literature but will consist rather of presentations of an interpretive and integrative nature, based on selection of major research advances. It is our aim that these volumes should provide the means whereby cell biologists may keep themselves reasonably well informed about the current progress in research areas in cell biology in which they are not immediately or directly involved themselves. The articles, nevertheless, are expected to bring into focus the experimental objectives of the specialists in a given research area. D. M.P. L. G. E.M. vii Contents Contributors v Preface vii 1 1.

Cause and Correlation in Biology


Book Description

This book goes beyond the truism that 'correlation does not imply causation' and explores the logical and methodological relationships between correlation and causation. It presents a series of statistical methods that can test, and potentially discover, cause-effect relationships between variables in situations in which it is not possible to conduct randomised or experimentally controlled experiments. Many of these methods are quite new and most are generally unknown to biologists. In addition to describing how to conduct these statistical tests, the book also puts the methods into historical context and explains when they can and cannot justifiably be used to test or discover causal claims. Written in a conversational style that minimises technical jargon, the book is aimed at practising biologists and advanced students, and assumes only a very basic knowledge of introductory statistics.




Sustaining and Improving Learning Communities


Book Description

Sustaining and Improving Learning Communities is the long awaited follow-up to the groundbreaking book Creating Learning Communities. The authors continue their exploration of the concept of learning communities as an innovation in undergraduate curricular instruction that allow students to actively participate in their own education, and deepen and diversify their college experience. Jodi Levine Laufgraben and Nancy S. Shapiro address a wide range of topics such as campus culture for sustaining learning communities, learning communities and the curriculum, pedagogies, and faculty development.
