The symposium editors review key issues concerning the relationship between risk communication and public participation
Topological Censorship
All three-manifolds are known to occur as Cauchy surfaces of asymptotically
flat vacuum spacetimes and of spacetimes with positive-energy sources. We prove
here the conjecture that general relativity does not allow an observer to probe
the topology of spacetime: any topological structure collapses too quickly to
allow light to traverse it. More precisely, in a globally hyperbolic,
asymptotically flat spacetime satisfying the null energy condition, every
causal curve from \scri^- to {\scri}^+ is homotopic to a topologically
trivial curve from \scri^- to {\scri}^+. (If the Poincar\'e conjecture is
false, the theorem does not prevent one from probing fake 3-spheres).Comment: 12 pages, REVTEX; 1 postscript figure in a separate uuencoded file.
Our earlier version (PRL 71, 1486 (1993)) contained a secondary result,
mistakenly attributed to Schoen and Yau, regarding ``passive topological
censorship'' of a certain class of topologies. As Gregory Burnett has pointed
out (gr-qc/9504012), this secondary result is false. The main topological
censorship theorem is unaffected by the erro

The Evolution of State Supreme Courts
Part I of this Article describes in broad quantitative terms the changing relationship between the caseload of supreme courts and the population of the states in which these courts sit. Part II examines the various means states used to control supreme court caseloads, the political problems involved, and the types of courts that have resulted. Part III presents evidence that changes in court organization in response to caseload pressure are accompanied by changes in the kinds of cases state supreme courts hear, the style of their opinions, and the results of the cases
