QCD and strongly coupled gauge theories : challenges and perspectives

We highlight the progress, current status, and open challenges of QCD-driven physics, in theory and in experiment. We discuss how the strong interaction is intimately connected to a broad sweep of physical problems, in settings ranging from astrophysics and cosmology to strongly coupled, complex systems in particle and condensed-matter physics, as well as to searches for physics beyond the Standard Model. We also discuss how success in describing the strong interaction impacts other fields, and, in turn, how such subjects can impact studies of the strong interaction. In the course of the work we offer a perspective on the many research streams which flow into and out of QCD, as well as a vision for future developments.Peer reviewe

Transition and trade perspectives on Eastern European agriculture

In the economic and political restructuring of Eastern Europe, a new agricultural structure is taking shape, based upon private ownership, genuine cooperatives, and a market economy. Agricultural trade policy in six Eastern European nations will be characterized by the aim of self-sufficiency, but privatized and centered around market methods, improvement in agricultural systems will occur slowly, and over the long term may achieve self-sufficiency and greater exports. Meanwhile, Eastern European agriculture will provide investment and market opportunities for countries of the developed world
