This book was released on 1990-10-26 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The seven articles in this volume are based on lectures presented at the annual symposium, Some Mathematical Questions in Biology, held in conjunction with the American Institute of Biological Sciences meeting in Toronto, Ontario in August 1989. Sexual selection, sex determination, and sex allocation have been at the center of evolutionary ecology since its inception and have played an important role in the development of many concepts. As this volume demonstrates, many key questions remain to be investigated through a combination of empirical and theoretical work. In addition, questions of sex provide a natural mechanism for crossing the great taxonomic divide by allowing plant and animal researchers to focus on similar kinds of questions using a wide variety of organisms.

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.

Download or read book Cell Biology written by Byron Goldstein and published by American Mathematical Soc.. This book was released on 1994-01-01 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the techniques of modern molecular biology continue to revolutionize experimental design in cell biology, mathematical modeling and analysis become increasingly necessary and feasible. The papers in this collection expand on invited lectures presented at the Symposium on Some Mathematical Questions in Biology: Cell Biology, held in November 1992 in Denver, Colorado. The work reviewed in the papers demonstrates the power of combining mathematics and experiment to study a number of cell processes, including: protein transport in nerve axons, formation of transport vesicles at the Golgi, molecular motion in cell membranes, cell adhesion, T lymphocyte activation, and cellular responses to receptor aggregation. The volume is an important contribution to the literature, as it introduces mathematicians to a growing application area and cell biologists to new tools and results. The individual articles can be used as readings in a course on mathematical modeling.

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.

Available in PDF, EPUB and Kindle. Book excerpt: We are experiencing an anthropological revolution. We see it in the #MeToo movement, in the denunciation of femicide and in an increasingly vociferous critique of patriarchal domination. Why this sudden rise of an antagonistic conception of the relationship between men and women, at the very moment when progress is accelerating and when the goals of first- and second-wave feminism seem on the verge of being achieved? In this book, the anthropologist and historian Emmanuel Todd, while not underestimating the importance of crucial inequalities that remain, argues that the emancipation of women has essentially already taken place but that it has given rise to new tensions and contradictions. As women gain more freedom, they also gain access to traditional male social pathologies: economic anxiety, the disorientation of anomie, and individual and class resentment. But because they remain women, with the ability to bear children, their burden as human beings, although richer, is now more difficult to bear than that of men. In order to understand our current condition, Todd retraces the evolution of the male/female relationship through the long history of the human species, from the emergence of Homo sapiens a hundred thousand years ago to the present. He also conducts a broad empirical study of the convergence between men and women today and of the differences that still separate them – in education, in employment and in relation to longevity, suicide and homicide, electoral behaviour and racism. He explores the relations between women’s liberation and other changes in contemporary societies such as the collapse of religion, the decline of industry, the decline of homophobia, the rise of bisexuality and the transgender phenomenon, and the decline in a sense of the collective life. And he shows how and why Western countries – and especially the Anglo-American world, Scandinavia and France – are, in their new feminist revolution, perhaps less universal than they think.
