Parental involvement with children at home, in school, and in the community is one of the most important factors in educational success. Yet we know very little about the most effective approaches to parental intervention. Moreover, not all parents have the same resources or opportunities to act on the educational expectations they have for their c

"There is in modem society a structural change that underlies many of the social changes with which the conference was concerned. My argument here will be that this is a qualitative change in the way society is organized, a change with many implications. I will call this a change from primordial and spontaneous social organization to constructed social organization (see Coleman 1990, Chapters 2, 3, and 24 for an extended examination of this change). The common definitions of these terms contain some hint of what I mean, but I will describe the change more fully to ensure that it is clearly understood. By primordial social organization I mean social organization that has its origins in the relationships established by childbirth. Not all these relations are activated in all cultures, but some subset of these relations forms the basis for all primitive and traditional social organization. From these relations, more complex structures unfold. For example, from these relations come families; from families come clans; from clans, villages; and from villages, tribes, ethnicities, or societies."

This book presents a major report that has evoked extensive controversy and initiated extensive policy debate on equality and achievement in education. It examines the concept of equality of educational opportunity and the relations between equality and achievement and between families and schools.

This landmark collection brings leading scholars in the field of political communication to debate one of the most important questions of our age: Can the media serve democracy? For the media to be democratic, they must enter into a positive relationship with their readers, viewers and listeners as citizens rather than consumers who buy things, audiences who gaze upon spectacles or isolated egos, obsessed with themselves. The media's first task is to remind people that they are inhabitants of a world in which they can make a difference. By enabling citizens to encounter and make sense of events, relationships and cultures of which they have no direct experience, the media constitute a public arena in which members of the public come together as more than passing strangers.

The purpose of this four volume series is to make available for college teachers and students samples of important and realistic applications of mathematics which can be covered in undergraduate programs. The goal is to provide illustrations of how modem mathematics is actually employed to solve relevant contemporary problems. Although these independent chapters were prepared primarily for teachers in the general mathematical sciences, they should prove valuable to students, teachers, and research scientists in many of the fields of application as well. Prerequisites for each chapter and suggestions for the teacher are provided. Several of these chapters have been tested in a variety of classroom settings, and all have undergone extensive peer review and revision. Illustrations and exercises are included in most chapters. Some units can be covered in one class, whereas others provide sufficient material for a few weeks of class time. Volume 1 contains 23 chapters and deals with differential equations and, in the last four chapters, problems leading to partial differential equations. Applications are taken from medicine, biology, traffic systems and several other fields. The 14 chapters in Volume 2 are devoted mostly to problems arising in political science, but they also address questions appearing in sociology and ecology. Topics covered include voting systems, weighted voting, proportional representation, coalitional values, and committees. The 14 chapters in Volume 3 emphasize discrete mathematical methods such as those which arise in graph theory, combinatorics, and networks.

All ruminants are dependent on the microorganisms that live in their forestomach - the rumen - to break down ingested feed constituents into a form that the host animal can utilize. Protozoa are part of this complex ruminal population and are essential for the nutritional well-being and productivity of the host ruminant. Over 30 different genera (nearly 300 species) of protozoa from the rumen ecosystem have been described since their initial discovery nearly 150 years ago. This book brings together, for the first time, the available information on these protozoa. It comprehensively describes the characteristic anatomical features of value for their identification and includes detailed sections on techniques and methodologies for the isolation and cultivation of these fastidious, oxygen-sensitive microorganisms. Their occurrence, biochemistry, physiology, and role in the ruminal ecosystem are fully reviewed. Particular emphasis is given to potential improvement of the nutrition and productivity of the host ruminant through manipulation of the protozoal population and its activities.

The method of normal forms is usually attributed to Poincare although some of the basic ideas of the method can be found in earlier works of Jacobi, Briot and Bouquet. In this book, A.D.Bruno gives an account of the work of these mathematicians and further developments as well as the results of his own extensive investigations on the subject. The book begins with a thorough presentation of the analytical techniques necessary for the implementation of the theory as well as an extensive description of the geometry of the Newton polygon. It then proceeds to discuss the normal form of systems of ordinary differential equations giving many specific applications of the theory. An underlying theme of the book is the unifying nature of the method of normal forms regarding techniques for the study of the local properties of ordinary differential equations. In the second part of the book it is shown, for a special class of equations, how the method of normal forms yields classical results of Lyapunov concerning families of periodic orbits in the neighborhood of equilibrium points of Hamiltonian systems as well as the more modern results concerning families of quasiperiodic orbits obtained by Kolmogorov, Arnold and Moser. The book is intended for mathematicians, theoretical mechanicians, and physicists. It is suitable for advanced undergraduate and graduate students.

From its inception as a public communication network, the Internet was regarded by many people as a potential means of escaping from the stranglehold of top-down, stage-managed politics. If hundreds of millions of people could be the producers as well as receivers of political messages, could that invigorate democracy? If political elites fail to respond to such energy, where will it leave them? In this short book, internationally renowned scholar of political communication, Stephen Coleman, argues that the best way to strengthen democracy is to re-invent it for the twenty-first century. Governments and global institutions have failed to seize the opportunity to democratise their ways of operating, but online citizens are ahead of them, developing practices that could revolutionise the exercise of political power.

This book examines the present and future of televised election debates, from the Nixon-Kennedy presidential debate of 1960 to the age of digital interactive multimedia. A number of contributors, from various perspectives - debate producers, participants and pundits - and from a variety of countries - Australia, New Zealand, Canada, USA, UK, Israel - discuss the significance of TV debates in what is the first international study of this important political phenomenon.

Parental involvement with children at home, in school, and in the community is one of the most important factors in educational success. Yet we know very little about the most effective approaches to parental intervention. Moreover, not all parents have the same resources or opportunities to act on the educational expectations they have for their children.This book examines the resources available to parents and the actions parents can take to further their children's education. It is the first study of the subject based on major survey data, drawing from the National Education Longitudinal Study of 1988--a national survey of 26,000 eighth graders, their parents, teachers, and school administrators. The authors explore several important debates, including the extent to which parental involvement can mitigate the constraints of poverty for minorities and disadvantaged students, school choice and equality of educational opportunity, and the effects that school-sponsored activities involving parents have on educational performance.Certain to change the thinking of educators and policymakers, this book is essential reading for scholars and parents as well.

The Media and the Public explores the ways a range of media, from the press to television to the Internet, have constructed and represented the public. Provides a new synthesis of recent research exploring the relationship between media and their publics Identifies ways in which different publics are subverting the gatekeeping of mainstream media in order to find a voice and communicate with others Situates contemporary media-public discourse and relationships in an historical context in order to show the origin of contemporary public/political engagement Creates a theoretical expansion on the role of the media in accessing or denying the articulation of public voices, and the ways in which publics are harnessing new media formats to produce richer and more complex forms of political engagement

Progressive multifocal leukoencephalopathy (PML) is a rare, disabling and potentially fatal brain infection of the central nervous system (CNS) caused by reactivation of the John Cunningham virus (JCV). The most important risk factor for PML is immunosuppression associated with HIV/AIDS or therapy. Approximately 60 to 80% of the adult population has JC antibodies, but PML is rarely diagnosed. The chapters in this book include research on the pathologic features of PML, the diagnosis, risk factors, pathogenesis, and management strategies.
