Defining the Problem and Searching for Solutions: Insurers, Employers, and State Government
Panel discussion: Some solutions to the uninsured problem happening right here in Cleveland. The Health Policy Coalition is a group which presents health insurance reform ideas to Congress. Charles Weller talked about the Coalition. Powell Woods described the Cleveland Health Quality Choice Program as follows: Cleveland Health Quality Choice is based upon the principle that if we figure out a way to reward high quality and cost efficiency as the twin lynch pins of reimbursement in our health purchasing system, we can drive both quality and efficiency gains in the system which can help produce savings which will in turn help underwrite the problem of coverage for the uninsured. E. John Polk discussed employee health insurance programs offered by the Council of Smaller Enterprises (COSE). Kenneth Seminatore represented Blue Cross and Blue Shield of Ohio. He proposed that the price escalation problem be solved by well-managed competition, such as that created by the 1987 of Senate Bill 124, the Health Insurance Reform Act. Mr. Seminatore also mentioned the problem of mandated benefits, stating, A study by Dr. John Goodman of Dallas indicates that perhaps 20 percent of the uninsured nationally are uninsured because they\u27re priced out of the market by mandated benefits they neither want, their insurance companies don\u27t want to offer, and they can\u27t afford. He also proposed Medicaid buy-in for the working poor

Structural, electronic, and dynamical properties of amorphous gallium arsenide: a comparison between two topological models
We present a detailed study of the effect of local chemical ordering on the
structural, electronic, and dynamical properties of amorphous gallium arsenide.
Using the recently-proposed ``activation-relaxation technique'' and empirical
potentials, we have constructed two 216-atom tetrahedral continuous random
networks with different topological properties, which were further relaxed
using tight-binding molecular dynamics. The first network corresponds to the
traditional, amorphous, Polk-type, network, randomly decorated with Ga and As
atoms. The second is an amorphous structure with a minimum of wrong (homopolar)
bonds, and therefore a minimum of odd-membered atomic rings, and thus
corresponds to the Connell-Temkin model. By comparing the structural,
electronic, and dynamical properties of these two models, we show that the
Connell-Temkin network is energetically favored over Polk, but that most
properties are little affected by the differences in topology. We conclude that
most indirect experimental evidence for the presence (or absence) of wrong
bonds is much weaker than previously believed and that only direct structural
measurements, i.e., of such quantities as partial radial distribution
functions, can provide quantitative information on these defects in a-GaAs.Comment: 10 pages, 7 ps figures with eps
Fast DNA translocation through a solid-state nanopore
We report translocation experiments on double-strand DNA through a silicon
oxide nanopore. Samples containing DNA fragments with seven different lengths
between 2000 to 96000 basepairs have been electrophoretically driven through a
10 nm pore. We find a power-law scaling of the translocation time versus
length, with an exponent of 1.26 0.07. This behavior is qualitatively
different from the linear behavior observed in similar experiments performed
with protein pores. We address the observed nonlinear scaling in a theoretical
model that describes experiments where hydrodynamic drag on the section of the
polymer outside the pore is the dominant force counteracting the driving. We
show that this is the case in our experiments and derive a power-law scaling
with an exponent of 1.18, in excellent agreement with our data.Comment: 5 pages, 2 figures. Submitted to PR
Use of ultrasound by emergency medical services: a review
Prehospital ultrasound has been deployed in certain areas of the USA and Europe. Physicians, emergency medical technicians, and flight nurses have utilized a variety of medical and trauma ultrasound assessments to impact patient care in the field. The goal of this review is to summarize the literature on emergency medical services (EMS) use of ultrasound to more clearly define the potential utility of this technology for prehospital providers
