BPST instanton and Spin from inequivalent quantizations

We present a simple alternative to Mackey's account of the (infinite) inequivalent quantizations possible on a coset space G/H. Our reformulation is based on the reduction ${\rm G \rightarrow G/H}$ and employs a generalized form of Dirac's approach to the quantization of constrained systems. When applied to the four-sphere $S^4 \simeq {\rm Spin(5)/Spin(4)}$, the inequivalent quantizations induce relativistic spin and a background BPST instanton; thus they might provide a natural account of both of these physical entities.Comment: 11 pages, plain TeX, PLY-MS-93-04, DIAS-STP-93-21 (This version should now TeX

Foreign and Religious Family Law: Comity, Contract, and the Constitution

The article focuses on role of the U.S. courts in confronting religious laws in dispute resolution of various cases of domestic relations, contracts, and torts. Topics discussed include role of secular courts in maintaining constitutional balance between the free exercise and establishment clauses, constitutional challenges faced by religious adherents, and importance of legal pluralism in the U.S

Family Governance in the Age of Divorce

In the age of divorce, the traditional picture of family governance has been substantially altered. The most striking aspects of this change are the result of new norms of family behavior. With large increases in the number of divorced and nonmarital families, many more families now find themselves before the courts disputing financial, child-rearing, and other questions. Within this context, the old rule of deference to private family governance is often not workable. These families are necessarily subject to a greater level of public intervention and regulation. But the forms of this regulation have also changed, reflecting a new and different understanding of privacy. In divorce, individuals are encouraged to resolve their differences through negotiation, with the courts acting as default decision-makers in cases of extreme conflict. Courts have moved toward greater protection of individual autonomy and privacy in matters of family life
