Book Description
The main problem with regard to alloplastic joints is the loosening of the implant. Twenty years ago, Charnley first introduced bone cement to hip surgery, enabling total hip replacement to be practised on a larger scale. There is no question, however, that new approaches must be found to solving the problems of implant loosening, either by developing a new type of cement or by directly anchoring the implant without using ce ment. Much research has been done in this direction in recent years. The methods which have already been tested or are currently being tested were presented and discussed at a symposium on Cementless Fixation of Endoprostheses organized by the Orthopaedic Clinic of the University of Basel and held on 24-26 June 1982. Various possible ap proaches which might be realized in practice were discussed in a relaxed atmosphere. In addition to the biomechanical bases of cementless fixa tion of endoprostheses, the various models were discussed, with special regard to their biocompatibility, physical characteristics, design, clinical applicability, and previous clinical experience. This book contains the papers delivered at this symposium.

Book Description
America's position as the source of much of the world's global innovation has been the foundation of its economic vitality and military power in the post-war. No longer is U.S. pre-eminence assured as a place to turn laboratory discoveries into new commercial products, companies, industries, and high-paying jobs. As the pillars of the U.S. innovation system erode through wavering financial and policy support, the rest of the world is racing to improve its capacity to generate new technologies and products, attract and grow existing industries, and build positions in the high technology industries of tomorrow. Rising to the Challenge: U.S. Innovation Policy for Global Economy emphasizes the importance of sustaining global leadership in the commercialization of innovation which is vital to America's security, its role as a world power, and the welfare of its people. The second decade of the 21st century is witnessing the rise of a global competition that is based on innovative advantage. To this end, both advanced as well as emerging nations are developing and pursuing policies and programs that are in many cases less constrained by ideological limitations on the role of government and the concept of free market economics. The rapid transformation of the global innovation landscape presents tremendous challenges as well as important opportunities for the United States. This report argues that far more vigorous attention be paid to capturing the outputs of innovation - the commercial products, the industries, and particularly high-quality jobs to restore full employment. America's economic and national security future depends on our succeeding in this endeavor.
Socratic Citizenship

Book Description
Many critics bemoan the lack of civic engagement in America. Tocqueville's ''nation of joiners'' seems to have become a nation of alienated individuals, disinclined to fulfill the obligations of citizenship or the responsibilities of self-government. In response, the critics urge community involvement and renewed education in the civic virtues. But what kind of civic engagement do we want, and what sort of citizenship should we encourage? In Socratic Citizenship, Dana Villa takes issue with those who would reduce citizenship to community involvement or to political participation for its own sake. He argues that we need to place more value on a form of conscientious, moderately alienated citizenship invented by Socrates, one that is critical in orientation and dissident in practice. Taking Plato's Apology of Socrates as his starting point, Villa argues that Socrates was the first to show, in his words and deeds, how moral and intellectual integrity can go hand in hand, and how they can constitute importantly civic--and not just philosophical or moral--virtues. More specifically, Socrates urged that good citizens should value this sort of integrity more highly than such apparent virtues as patriotism, political participation, piety, and unwavering obedience to the law. Yet Socrates' radical redefinition of citizenship has had relatively little influence on Western political thought. Villa considers how the Socratic idea of the thinking citizen is treated by five of the most influential political thinkers of the past two centuries--John Stuart Mill, Friedrich Nietzsche, Max Weber, Hannah Arendt, and Leo Strauss. In doing so, he not only deepens our understanding of these thinkers' work and of modern ideas of citizenship, he also shows how the fragile Socratic idea of citizenship has been lost through a persistent devaluation of independent thought and action in public life. Engaging current debates among political and social theorists, this insightful book shows how we must reconceive the idea of good citizenship if we are to begin to address the shaky fundamentals of civic culture in America today.
Affine and Projective Geometry

ISBN: 1118030826
Category : Mathematics
Languages : en
Pages : 251
Book Description
An important new perspective on AFFINE AND PROJECTIVEGEOMETRY This innovative book treats math majors and math education studentsto a fresh look at affine and projective geometry from algebraic,synthetic, and lattice theoretic points of view. Affine and Projective Geometry comes complete with ninetyillustrations, and numerous examples and exercises, coveringmaterial for two semesters of upper-level undergraduatemathematics. The first part of the book deals with the correlationbetween synthetic geometry and linear algebra. In the second part,geometry is used to introduce lattice theory, and the bookculminates with the fundamental theorem of projectivegeometry. While emphasizing affine geometry and its basis in Euclideanconcepts, the book: * Builds an appreciation of the geometric nature of linear algebra * Expands students' understanding of abstract algebra with itsnontraditional, geometry-driven approach * Demonstrates how one branch of mathematics can be used to provetheorems in another * Provides opportunities for further investigation of mathematicsby various means, including historical references at the ends ofchapters Throughout, the text explores geometry's correlation to algebra inways that are meant to foster inquiry and develop mathematicalinsights whether or not one has a background in algebra. Theinsight offered is particularly important for prospective secondaryteachers who must major in the subject they teach to fulfill thelicensing requirements of many states. Affine and ProjectiveGeometry's broad scope and its communicative tone make it an idealchoice for all students and professionals who would like to furthertheir understanding of things mathematical.

Book Description
This volume contains the lecture notes prepared for the AMS Short Course on Matrix Theory and Applications, held in Phoenix in January, 1989. Matrix theory continues to enjoy a renaissance that has accelerated in the past decade, in part because of stimulation from a variety of applications and considerable interplay with other parts of mathematics. In addition, the great increase in the number and vitality of specialists in the field has dispelled the popular misconception that the subject has been fully researched.
