Designing Administrative Organizations for Health Reform
Describes proposals to create new entities to research comparative effectiveness, make coverage decisions, manage health insurance markets, or offer a public health insurance plan. Discusses types of agencies and considerations for organizational design
Rayleigh-Brillouin scattering of carbon dioxide
The spectral lineshape of spontaneous Rayleigh-Brillouin scattering in CO2 is
studied in a range of pressures. The spectrum is influenced by the bulk
viscosity, which is a relaxation phenomenon involving the internal degrees of
freedom of the molecule. The associated relaxation rates can be compared to the
frequency shift of the scattered light, which demands precise measurements of
the spectral lineshape. We find the value of the bulk viscosity around 5.7 X
10^{-6} kg/(ms) for the range of pressures p= 2-4 bar and for conditions of
room temperature
Administering Health Insurance Mandates
Provides an overview of health insurance mandates and administrative considerations. Based on a review of existing and proposed employer and individual mandates, outlines ways to structure them to be administered fairly and effectively
Governance Issues for Health Insurance Exchanges
Outlines considerations for states in deciding how to structure a health insurance exchange, as well as issues of funding sources, operational flexibility, political independence and accountability, management structure, and sub-state dimensions
B_K in Staggered Chiral Perturbation Theory
We calculate the kaon B-parameter, B_K, to next-to-leading order in staggered
chiral perturbation theory. We find expressions for partially quenched QCD with
three sea quarks, quenched QCD, and full QCD with m_u = m_d but not equal to
m_s. We extend the usual power counting to include the effects of using
perturbative (rather than non-perturbative) matching factors. Taste breaking
enters through the O(a^2) terms in the effective action, through O(a^2) terms
from the discretization of operators, and through the truncation of matching
factors. These effects cause mixing with several additional operators,
complicating the chiral and continuum extrapolations. In addition to the
staggered expressions, we present B_K at next-to-leading order in continuum
partially quenched chiral perturbation theory for N_f=3 sea quarks with m_u =
m_d but not equal to m_s.Comment: 56 pages, 3 figures (v3: Corrected normalization error in Eq.(4) and
