Book Description
A famed political scientist's classic argument for a more cooperative world We assume that, in a world ruled by natural selection, selfishness pays. So why cooperate? In The Evolution of Cooperation, political scientist Robert Axelrod seeks to answer this question. In 1980, he organized the famed Computer Prisoners Dilemma Tournament, which sought to find the optimal strategy for survival in a particular game. Over and over, the simplest strategy, a cooperative program called Tit for Tat, shut out the competition. In other words, cooperation, not unfettered competition, turns out to be our best chance for survival. A vital book for leaders and decision makers, The Evolution of Cooperation reveals how cooperative principles help us think better about everything from military strategy, to political elections, to family dynamics.

Creationism USA
Author: Adam Laats
Publisher: Oxford University Press
ISBN: 0197516610
Category : Religion
Languages : en
Pages : 256
Book Description
Who are America's creationists? What do they want? Do they truly believe Jesus rode around on dinosaurs, as sometimes depicted? Creationism USA reveals how common misconceptions about creationism have led Americans into a century of unnecessary culture-war histrionics about evolution education and creationism. Adam Laats argues that Americans do not have deep, fundamental disagreements about evolution - not about the actual science behind it and not in ways that truly matter to public policy. Laats asserts that Americans do, however, have significant disagreements about creationism. By describing the history of creationism and its many variations, Laats demonstrates that the real conflict about evolution is not between creationists and evolution. The true landscape of American creationism is far more complicated than headlines suggest. Creationism USA digs beyond those headlines to prove two fundamental facts about American creationism. First, almost all Americans can be classified as creationists of one type or another. Second, nearly all Americans (including self-identified creationists) want their children to learn mainstream evolutionary science. Taken together, these truths about American creationism point to a large and productive middle ground, a widely shared public vision of the proper relationship between schools, science, and religion. Creationism USA both explains the current state of America's battles over creationism and offers a nuanced yet straight-forward prescription to solve them.

Teaching & Researching Big History: Exploring a New Scholarly Field
Author: Leonid Grinin
Publisher: ООО "Издательство "Учитель"
ISBN: 5705740271
Category : Human evolution
Languages : en
Pages : 368
Book Description
According to the working definition of the International Big History Association, ‘Big History seeks to understand the integrated history of the Cosmos, Earth, Life and Humanity, using the best available empirical evidence and scholarly methods.’ In recent years Big History has been developing very fast indeed. Big History courses are taught in the schools and universities of several dozen countries. Hundreds of researchers are involved in studying and teaching Big History. The unique approach of Big History, the interdisciplinary genre of history that deals with the grand narrative of 13.8 billion years, has opened up a vast amount of research agendas. Big History brings together constantly updated information from the scientific disciplines and merges it with the contemplative realms of philosophy and the humanities. It also provides a connection between the past, present, and future. Big History is a colossal and extremely heterogeneous field of research encompassing all the forms of existence and all timescales. Unsurprisingly, Big History may be presented in very different aspects and facets. In this volume the Big History is presented and discussed in three different ways. In its first part, Big History is explored in terms of methodology, theories of knowledge, as well as showcasing the personal approach of scholars to Big History. The second section comprises such articles that could clarify Big History's main trends and laws. The third part of this book explores the nature of teaching Big History as well as profiling a number of educational methods. This volume will be useful both for those who study interdisciplinary macroproblems and for specialists working in focused directions, as well as for those who are interested in evolutionary issues of Astrophysics, Geology, Biology, History, Anthropology, Linguistics and other areas of study. More than that, this edition will challenge and excite your vision of your own life and the exciting new discoveries going on around us!

Evolution's Rainbow
Author: Joan Roughgarden
Publisher: Univ of California Press
ISBN: 0520957970
Category : Science
Languages : en
Pages : 491
Book Description
In this innovative celebration of diversity and affirmation of individuality in animals and humans, Joan Roughgarden challenges accepted wisdom about gender identity and sexual orientation. A distinguished evolutionary biologist, Roughgarden takes on the medical establishment, the Bible, social science—and even Darwin himself. She leads the reader through a fascinating discussion of diversity in gender and sexuality among fish, reptiles, amphibians, birds, and mammals, including primates. Evolution's Rainbow explains how this diversity develops from the action of genes and hormones and how people come to differ from each other in all aspects of body and behavior. Roughgarden reconstructs primary science in light of feminist, gay, and transgender criticism and redefines our understanding of sex, gender, and sexuality. Witty, playful, and daring, this book will revolutionize our understanding of sexuality. Roughgarden argues that principal elements of Darwinian sexual selection theory are false and suggests a new theory that emphasizes social inclusion and control of access to resources and mating opportunity. She disputes a range of scientific and medical concepts, including Wilson's genetic determinism of behavior, evolutionary psychology, the existence of a gay gene, the role of parenting in determining gender identity, and Dawkins's "selfish gene" as the driver of natural selection. She dares social science to respect the agency and rationality of diverse people; shows that many cultures across the world and throughout history accommodate people we label today as lesbian, gay, and transgendered; and calls on the Christian religion to acknowledge the Bible's many passages endorsing diversity in gender and sexuality. Evolution's Rainbow concludes with bold recommendations for improving education in biology, psychology, and medicine; for democratizing genetic engineering and medical practice; and for building a public monument to affirm diversity as one of our nation's defining principles.

The Evolution of the Costumed Avenger
Author: Jess Nevins
Publisher: Bloomsbury Publishing USA
ISBN: 144085484X
Category : Comics & Graphic Novels
Languages : en
Pages : 420
Book Description
Using a broad array of historical and literary sources, this book presents an unprecedented detailed history of the superhero and its development across the course of human history. How has the concept of the superhero developed over time? How has humanity's idealization of heroes with superhuman powers changed across millennia—and what superhero themes remain constant? Why does the idea of a superhero remain so powerful and relevant in the modern context, when our real-life technological capabilities arguably surpass the imagined superpowers of superheroes of the past? The Evolution of the Costumed Avenger: The 4,000-Year History of the Superhero is the first complete history of superheroes that thoroughly traces the development of superheroes, from their beginning in 2100 B.C.E. with the Epic of Gilgamesh to their fully entrenched status in modern pop culture and the comic book and graphic novel worlds. The book documents how the two modern superhero archetypes—the Costumed Avengers and the superhuman Supermen—can be traced back more than two centuries; turns a critical, evaluative eye upon the post-Superman history of the superhero; and shows how modern superheroes were created and influenced by sources as various as Egyptian poems, biblical heroes, medieval epics, Elizabethan urban legends, Jacobean masques, Gothic novels, dime novels, the Molly Maguires, the Ku Klux Klan, and pulp magazines. This work serves undergraduate or graduate students writing papers, professors or independent scholars, and anyone interested in learning about superheroes.

The Hospitable Canon
Author: Virgil Nemoianu
Publisher: John Benjamins Publishing
ISBN: 9027242372
Category : Literary Criticism
Languages : en
Pages : 280
Book Description
The papers in this book respond to the public debate over literary canons, in the United States, and elsewhere, by placing the political-ideological aspects of the conflict inside perspectives derived from comparative literature. Canons are seen by most of the contributors as based on democratic and communal intentions or choices inevitable filtered through and colored by historical experiences and social biases.An examination of the canonical process over many centuries reveals both the impressive durability of its elements and the amazing flexibility of its outlines. The careful individual analyses, as well as the thought-provoking general contributions in this volume agree that the democracy of play is one of the strongest bonds uniting the human race. Canons or canons, the contributors argue, are based on it and reflect the intimate interdependence of cultural and intellectual matters with the workings of society as a whole. Contributors Charles Altieri, Lilian R. Furst, Michael G. Cooke, Robert Royal, Roger Shattuck, Rosa E.M.D. Penna, Glen M. Johnson, Yves Chevrel, Raymond A. Prier, Peter Walker, Christopher Clausen, Virgil Nemoianu.

Conrad Aiken
Author: Edward Butscher
Publisher: University of Georgia Press
ISBN: 0820336203
Category : Biography & Autobiography
Languages : en
Pages : 546
Book Description
The first of a planned two-volume biography, Conrad Aiken: Poet of White Horse Vale follows Aiken's early life from his birth in 1889 to 1925 when he stood on the threshold of both nervous breakdown and poetic success. It was then that Aiken began to face his paradoxically idyllic and tragic Savannah childhood and to confront the events of February 27, 1901. On that day, the eleven-year-old Aiken heard gunshots punctuate a nightlong argument between his mother and father. Running into the next room, he discovered his mother murdered and his father dead by suicide. Sounding the deep reverberations of those events in Aiken's mind, Edward Butscher follows the poet's life and work as he sought to regain, in some permanent form, the idyll he had lost as a child. Butscher tells of Aiken's determined efforts to gain recognition for his verse in the fevered cultural circuits of the early twentieth century—from his friendship, begun at Harvard, with T. S. Eliot, through frustrating excursions into the literary society of England and repeated trips on the poetic “trade route” from his home in Boston to Chicago and New York, to often sharp encounters with such powerful cultural barons as Ezra Pound, Amy Lowell, and Harriet Monroe. Hoping to build his reputation on a series of detached poetic “symphonies,” to keep depression from boiling over into madness and suicide, Aiken skirted the border of his deepest memories and fears—a border he would cross in the works that lay ahead.

The Evolution of Library and Museum Partnerships

ISBN: 0313058857
Category : Language Arts & Disciplines
Languages : en
Pages : 260
Book Description
These authors examine the unique social roles of libraries and museums, review historical precedents as well as library-museum partnerships funded in recent years through IMLS grants, and forge an exciting vision of a new library-museum hybrid. The juxtaposition of library collections and museum artifacts, they assert, has the potential to create authentic, interactive experiences for community members, and it can help establish a distinct, meaningful, and sustainable role for libraries. In the authors' words, libraries can then reassert themselves as places devoted to contemplation, wonder, knowledge acquisition, and critical inquiry. Commercialization, edutainment, and the library as a learning community are just some of the fascinating topics addressed as the authors explore the future's terrain, and suggest how libraries might situate themselves upon it. Libraries, museums, and the ways in which they are used by patrons have drastically changed in past decades. Digitization projects, infotainment, and the Internet are redefining the library's and the museum's roles in the community. What are the implications for the future of these institutions?

The Evolution of Political Knowledge
Author: American Political Science Association. Meeting
Publisher: Ohio State University Press
ISBN: 0814209335
Category : Political Science
Languages : en
Pages : 380
Book Description
Over the course of the last century, political scientists have been moved by two principal purposes. First, they have sought to understand and explain political phenomena in a way that is both theoretically and empirically grounded. Second, they have analyzed matters of enduring public interest, whether in terms of public policy and political action, fidelity between principle and practice in the organization and conduct of government, or the conditions of freedom, whether of citizens or of states. Many of the central advances made in the field have been prompted by a desire to improve both the quality and our understanding of political life. Nowhere is this tendency more apparent than in research on American politics, a field in which concerns for the public interest have stimulated various important insights. This volume systematically analyzes the major developments within the broad field of American politics over the past three decades. Each chapter is composed of a core paper that addresses the major puzzles, conversations, and debates that have attended major areas of concern and inquiry within the discipline. These papers examine and evaluate the intellectual evolution and "natural history" of major areas of political inquiry and chart particularly promising trajectories, puzzles, and concerns for future work Each core paper is accompanied by a set of shorter commentaries that engage the issues it takes up, thus contributing to an ongoing and lively dialogue among key figures in the field.
