Quasi-Einstein metrics on hypersurface families

We construct quasi-Einstein metrics on some hypersurface families. The hypersurfaces are circle bundles over the product of Fano, K\"ahler-Einstein manifolds. The quasi-Einstein metrics are related to various gradient K\"ahler-Ricci solitons constructed by Dancer and Wang and some Hermitian, non-K\"ahler, Einstein metrics constructed by Wang and Wang on the same manifolds.Comment: 11 pages, v2 expanded and references added.

The Out-Front Western Region: An Overview

This report is part of a series of 21 state and regional studies examining the rollout of the ACA. The national network ---- with 36 states and 61 researchers ---- is led by the Rockefeller Institute of Government, the public policy research arm of the State University of New York, the Brookings Institution, and the Fels Institute of Government at the University of Pennsylvania.This first "Special Analysis Report" focuses on the Western region, which has the largest number of states -- six out of thirteen -- that are affirmatively implementing the Affordable Care Act. That is, they have state-administered health insurance exchanges and have expanded Medicaid as authorized under the law. Altogether, there are eleven states in the Western region of the contiguous states, and nine of them are in our sample. This report describes the policy setting and goal alignment of all nine Western sample states, with emphasis on five states -- California, Oregon, Washington, Colorado, and Nevada -- that are clearly out front as ACA-affirming states. New Mexico is also an affirming ACA state, although its exchange will not be state run until 2014. Arizona and Idaho occupy an "In-Between" category; that is, in between affirming and oppositional. Arizona rejected the state-run exchange option but accepted Medicaid expansion. Idaho so far has done the opposite, accepting the state-run exchange option while tabling Medicaid expansion. Utah is the one fully oppositional state in our sample, choosing in 2013 not to run its exchange or expand Medicaid

On the linear stability of K\"ahler-Ricci solitons

This is a short note proving that K\"ahler-Ricci solitons with $\dim H^{(1,1)}(M)\ge 2$ are linearly unstable. This extends the results of Cao-Hamilton-Ilmanen in the K\"ahler-Einstein case.Comment: 11 pages; typos corrected, presentation improved and references added in v.

Arizona: Round 1 - State-Level Field Network Study of the Implementation of the Affordable Care Act

This report is part of a series of 21 state and regional studies examining the rollout of the ACA. The national network -- with 36 states and 61 researchers -- is led by the Rockefeller Institute of Government, the public policy research arm of the State University of New York, the Brookings Institution, and the Fels Institute of Government at the University of Pennsylvania.A number of decisions helped set the stage for Arizona's implementation of the Affordable Care Act (ACA). These decisions and the dynamics that led to them reflect a complex mix of intergovernmental political calculation and pragmatic public policy, past and present, which frame the state's capacity for implementing ACA in Arizona

Releasing wind farm equity via post-construction yield analysis

During pre-construction yield analysis, an extrapolated site wind regime is applied to a site model in order to produce estimated yield figures. However, once the site has been operational, many of the uncertainties involved in this modelling, such as electrical losses, wake losses, turbulence and power performance, may be resolved into measured operational parameters. This means that off-site anemometry may be directly related to power production on the site. In a post-construction yield analysis, the pre-construction figures are refined using actual operational data. This allows: a) The initial yield report figures to be reassessed in the light of wind farm performance, and b) The uncertainties associated with annual yield figures to be reduced and understood more fully. This increasing reduction in uncertainty allows improvements in financial modelling to take place over the operational life of the wind farm, releasing equity from the wind farm investmen
