The Mobility Case for Regionalism
In the discourse of local government law, the idea that a mobile populace can “vote with its feet” has long served as a justification for devolution and decentralization. Tracing to Charles Tiebout’s seminal work in public finance, the legal-structural prescription that follows is that a diversity of independent and empowered local governments can best satisfy the varied preferences of residents metaphorically shopping for bundles of public services, regulatory environment, and tax burden. This localist paradigm generally presumes that fragmented governments are competing for residents within a given metropolitan area. Contemporary patterns of mobility, however, call into question this foundational assumption. People today move between — and not just within — metropolitan regions, domestically and even internationally. This is particularly so for a subset of residents — high human-capital knowledge workers and the so-called “creative class” — that is prominently coveted in this interregional competition. These modern mobile residents tend to evaluate the policy bundles that drive their locational decisions on a regional scale, weighing the comparative merits of metropolitan areas against each other. And local governments are increasingly recognizing that they need to work together at a regional scale to compete for these residents.This Article argues that this intermetropolitan mobility provides a novel justification for regionalism that counterbalances the strong localist tendency of the traditional Tieboutian view of local governance. Contrary to the predominant assumption in the legal literature, competition for mobile residents is as much an argument for regionalism as it has been for devolution and decentralization. In an era of global cities vying for talent, the mobility case for regionalism has significant doctrinal consequences for debates in local government law and public finance, including the scope of local authority, the nature of regional equity, and the structure of metropolitan collaboration
Parton Distributions Functions of Pion, Kaon and Eta pseudoscalar mesons in the NJL model
Parton distributions of pseudoscalar pi,K and eta mesons obtained within the
NJL model using the Pauli-Villars regularization method are analyzed in terms
of LO and NLO evolution, and the valence sea quark and gluon parton
distributions for the pion are obtained at Q^2 = 4 GeV^2 and compared to
existing parametrizations at that scale. Surprisingly, the NLO order effects
turn out to be small compared to the LO ones. The valence distributions are in
good agreement with experimental analyses, but the gluon and sea distributions
come out to be softer in the high-x region and harder in the low-x region than
the experimental analyses suggest.Comment: (Latex, epsfig) 17 pages, 7 figure

Analysis of the Low-Energy Theorem for \gamma p \to p \pi^0
The derivation of the `classical' low-energy theorem (LET) for \gamma p
\rightarrow p\pi^0 is re-examined and compared to chiral perturbation theory.
Both results are correct and are not contradictory; they differ because
different expansions of the same quantity are involved. Possible modifications
of the extended partially conserved axial-vector current relation, one of the
starting points in the derivation of the LET, are discussed. An alternate, more
transparent form of the LET is presented.Comment: 5 pages, Revtex, no figures, no table
