On the measurement of market-oriented reforms

This paper presents policy- and outcome-based ways of measuring the progress of market-oriented reforms in both traditional areas of first-generation reform and the areas of institutional reform that have been emphasized lately. These policy areas are the domestic financial system; international financial markets; international trade; the labor market; the tax system; public infrastructure and public firms; the legal and regulatory framework; and governance. For each of them, first, we discuss the general principles underlying market-oriented reform; second, we present various indicators of the policy stance in the area in question; and third, we present various outcome indicators of the policy stance.Banks&Banking Reform,Economic Theory&Research,Payment Systems&Infrastructure,Environmental Economics&Policies,Labor Policies,Economic Theory&Research,Environmental Economics&Policies,Banks&Banking Reform,Financial Intermediation,TF054105-DONOR FUNDED OPERATION ADMINISTRATION FEE INCOME AND EXPENSE ACCOUNT

Three different approaches to the same interaction: the Yukawa model in nuclear physics

After a brief discussion of the meaning of the potential in quantum mechanics, we examine the results of the Yukawa model (scalar meson exchange) for the nucleon-nucleon interaction in three different dynamical frameworks: the non-relativistic dynamics of the Schrodinger equation, the relativistic quantum mechanics of the Bethe-Salpeter and Light-Front equations and the lattice solution of the Quantum Field Theory, obtained in the quenched approximation.Comment: 17 pages, 9 figures.

Taking dibaryon fields seriously

We propose a low energy effective field theory of QCD at the scale of pion mass for the $N_B=2$ sector, $N_B$ being the baryon number, which contains two dibaryon fields in addition to the nucleons and pions. It has a well defined counting, is renormalizable and the nucleon-nucleon scattering amplitudes are manifestly unitary at leading order. We work out a lower energy effective theory for nucleons with energy much lower than the pion mass and three momentum comparable to it, which also has a well defined counting and is renormalizable. The dibaryon fields must also be kept as explicit degrees of freedom in this theory. We calculate the scattering amplitudes at next-to-leading order for the $^1S_0$ and $^3S_1$ channels in this framework and obtain an excellent description of the phase shifts for center of mass energies in the $0-50 MeV$ range.Comment: 20 pages, 5 figures; misprints corrected, explanations enlarged, references added.

Model Independent Results for Heavy Quarkonium

We review a number of results for the spectrum and inclusive decays of heavy quarkonium systems which can be derived from QCD under well controlled approximations. They essentially follow from the hierarchy of scales in these systems, which can be efficiently exploited using non-relativistic effective field theories. In particular, we discuss under which conditions non-relativistic potential models emerge as effective theories of QCD.Comment: 15 pages. Invited brief revie

Geographical extrapolation domain analysis: Scaling up watershed management research projects, a toolkit to guide implementation

Funding agencies, research programs, and organizations involved in the implementation of research need to know the potential worldwide impact and applicability of their efforts and investments. The extrapolation domain analysis method (EDA) was developed to produce information about the location, areas, and population potentially influenced by research outputs. This working paper presents detailed steps how to implement an EDA. For a particular research project, it starts with establishing a baseline assessment of the project, and proceeds through data collection, preparation, and similarity modeling concluding with reporting and validation. The guide is designed for users with intermediate knowledge of GIS and Bayesian statistics for a smooth and easy implementation of the method. It also requires the participation of the members of the research project for proper identification of key variables to be used in the process
