In the essays that follow, Fred Berger argues for freedom of expression, civil disobedience, affirmative action and what he calls liberal judicial activism and against sex-role stereotyping, paternalism and the censorship of pornography. Underlying his liberalism is a unified theory. That theory consists of a conception of rights, a theory of value and a theory of government. The conception of a right that Berger defends derives from J ohn Stuart Mill and is captured by what he calls "the rights- formula": to have a right is to have important interests that society ought to protect as a...

The Annual Beltsville Symposium provides a forum for interaction among scientists involved in research that has vital impact on agriculture and on the agricultural sciences. The 10th Symposium in the series, Biotechnology for Solving Agricultural Problems, focuses on the use of a revolutionary new set of tools, biotechnology, and attempts to define the set in terms of its applications in agriculture. Biotechnology has already contributed to the genetic improvement of agricultural products. Procedures that were impossible to test or to implement in the past because of technological limitations...

The Annual Beltsville Symposium serves as a forum for presenting recent developments in basic research that contribute solutions to agricultural problems. The eleventh in this series focuses on instrumentation tech niques which provide powerful new research tools. These tools will provide information that can lead to a better understanding of biological and physical processes critical to the solution of today's agricultural problems. The tools discussed include isotope technology, separation techniques, microscopy, electro-magnetic spectroscopy, resonance and mass spectrometry and...

Papers Presented at a Symposium held May 8--11, 1989, at the Beltsville Agricultural Research Center (BARC), Beltsville, Maryland, U.S.A.

Topics for the Beltsville Symposia are selected to highlight specific areas of research and science policy that are of concern to scientists in the Beltsville Area as well as to the general scientific community. Each sympo- sium in the series is structured to provide a realistic appraisal of current findings, research progress, and relevant policy issues within the constraints established by the organizing committee. Thus, the presentations and dis- cussions that have marked these symposia have had a strong appeal to the broad community of scientists. Knowledge of the diversity of living...
