Seven-Period Asteroseismic Fit of the Kepler DBV
We present a new, better-constrained asteroseismic analysis of the
helium-atmosphere (DB) white dwarf discovered in the field of view of the
original Kepler mission. Observations obtained over the course of two years
yield at least seven independent modes, two more than were found in the
discovery paper for the object. With several triplets and doublets, we are able
to fix the and identification of several modes before
performing the fitting, greatly reducing the number of assumptions we must make
about mode identification. We find a very thin helium layer for this relatively
hot DB, which adds evidence to the hypothesis that helium diffuses outward
during DB cooling. At least a few of the modes appear to be stable on
evolutionary timescales and could allow us to obtain a measurement of the rate
of cooling with monitoring of the star over the course of the next few years
with ground-based follow-up.Comment: 24 pages, 4 figures. 2 tables. Published fall 2014 in the

Paying primary health care centers for performance in Rwanda
Paying for performance (P4P) provides financial incentives for providers to increase the use and quality of care. P4P can affect health care by providing incentives for providers to put more effort into specific activities, and by increasing the amount of resources available to finance the delivery of services. This paper evaluates the impact of P4P on the use and quality of prenatal, institutional delivery, and child preventive care using data produced from a prospective quasi-experimental evaluation nested into the national rollout of P4P in Rwanda. Treatment facilities were enrolled in the P4P scheme in 2006 and comparison facilities were enrolled two years later. The incentive effect is isolated from the resource effect by increasing comparison facilities'input-based budgets by the average P4P payments to the treatment facilities. The data were collected from 166 facilities and a random sample of 2158 households. P4P had a large and significant positive impact on institutional deliveries and preventive care visits by young children, and improved quality of prenatal care. The authors find no effect on the number of prenatal care visits or on immunization rates. P4P had the greatest effect on those services that had the highest payment rates and needed the lowest provider effort. P4P financial performance incentives can improve both the use of and the quality of health services. Because the analysis isolates the incentive effect from the resource effect in P4P, the results indicate that an equal amount of financial resources without the incentives would not have achieved the same gain in outcomes.Health Monitoring&Evaluation,Population Policies,Health Systems Development&Reform,Disease Control&Prevention,Adolescent Health
Formulary status of cephalosporins
The primary purpose of this study is to analyze the formulary status of cephalosporins among a representative sample of hospitals in the United States. In addition, the research design attempts to determine the ranking of cephalsoporins in terms of acceptance to the hospitals\u27 formulary and actual stocking of the cephaosoporin products. The study will attempt to ascertain the reasons for these rankings and the influence of DRG implementation, teaching status and hospital bed size on number of cephalosporins on formulary and in stock. This may yield insight into the strategies that hospitals are currently using to contain a significant proportion of their budget for pharmaceutical product

Photoproduction with a mini-jet model and Cosmic Ray showers
We present post-LHC updates of estimates of the total photo-production cross
section in a mini-jet model with infrared soft gluon resummation, and apply the
model to study Cosmic Ray shower development, comparing the results with those
obtained from other existing models.Comment: 7 pages, 5 figures, presented at Photon 2017, 22-26 May 2017 CER
