Sleep apnoea and its impact on public health

In 1997 we published a systematic review on the health effects of obstructive sleep apnoea and the effectiveness of treatment with CPAP. This generated much controversy and considerable correspondence. About half the letters received by the authors suggested that the paper was just stating the obvious, the other half that the paper was completely inaccurate. To help clarify our findings this paper will discuss the public health impact of sleep apnoea and the rationale behind systematic reviews

Social Security Disability Insurance, Medicare And Work: A Review of the SSDI and Medicare Rules Related to Work Activity. Guidelines for Proactively Using the SSDI and Medicare Work Incentives to Help Individuals with Disabilities Maximize Independence Through Work

This policy-to-practice brief will focus on issues related to benefits and work for the SSDI beneficiary. After first explaining what SSDI is and the differences between SSDI and SSI, we will explain two historical work disincentives: the substantial gainful activity (SGA) rule and the continuing disability review (CDR). We will then explore a number of work incentives or special rules that seek to encourage work by either allowing benefits to continue for limited periods while working (trial work period (TWP), extended period of eligibility (EPE)), or allow individuals to quickly return to benefits status when a work effort stops or wage levels dip below the SGA level (expedited reinstatement). We will also explain special rules for either ignoring some short-term employment efforts (unsuccessful work attempts) or reducing countable monthly wages to be measured against the SGA amount for the year in question (impairment related work expenses, subsidies, paid time off)

The Medicaid Buy-In for Working People With Disabilities: Individuals With Disabilities Can Earn Significant Wages and Qualify for This Important Health Care Benefit

This policy-to-practice brief provides an in-depth illustrated description of the Plan for Achieving Self-Support (PASS) work incentives. This brief reviews how the PASS can be used to promote a work goal; the criteria for approving a PASS; and how the PASS can be used in conjunction with other programs to promote and achieve vocational success. Throughout the brief, examples are used to illustrate principles and provide an example in the appendices to show how to propose a PASS that meets all of SSA’s criteria for approval. Extensive citations to law, regulation, and policy appear in footnotes to maximize the usefulness of this publication to benefits planners who are engaged in writing PASS proposals for individuals

WORKING: The Newsletter of the New York Makes Work Pay Initiative

WELCOME to the inaugural issue of Working, a print and elec¬tronic newsletter produced by the New York Makes Work Pay Initiative. This Initiative is a Comprehensive Employment Ser¬vices Medicaid Infrastructure Grant funded by the U.S. Department of Health and Human Services, Centers for Medicare and Medicaid Services (CMS) to the New York State Office of Mental Health (OMH) and its management partners the Burton Blatt Institute (BBI) at Syra¬cuse University and the Employment and Disability Institute (EDI) at Cornell University. The New York Makes Work Pay Initiative is currently funded for calendar years 2009 and 2010 and will provide an array of services to individuals with disabilities, the agencies and advocates that serve them, and employers, helping to remove obstacles to work and pave the way to self-supporting employment

T-Branes and Geometry

T-branes are a non-abelian generalization of intersecting branes in which the matrix of normal deformations is nilpotent along some subspace. In this paper we study the geometric remnant of this open string data for six-dimensional F-theory vacua. We show that in the dual M-theory / IIA compactification on a smooth Calabi-Yau threefold X, the geometric remnant of T-brane data translates to periods of the three-form potential valued in the intermediate Jacobian of X. Starting from a smoothing of a singular Calabi-Yau, we show how to track this data in singular limits using the theory of limiting mixed Hodge structures, which in turn directly points to an emergent Hitchin-like system coupled to defects. We argue that the physical data of an F-theory compactification on a singular threefold involves specifying both a geometry as well as the remnant of three-form potential moduli and flux which is localized on the discriminant. We give examples of T-branes in compact F-theory models with heterotic duals, and comment on the extension of our results to four-dimensional vacua.Comment: v2: 80 pages, 2 figures, clarifications and references added, typos correcte

Launching Literacy in After-School Programs: Early Lessons from the CORAL Initiative

The James Irvine Foundation launched the Communities Organizing Resources to Advance Learning (CORAL) initiative in 1999 with the goal of improving the academic achievement of children in the lowest-performing schools in five California cities. In 2004, CORAL adopted a more targeted approach toward reaching this goal by integrating a regular schedule of literacy instruction into its after-school programs. This interim report, based on research conducted between Fall 2004 and Summer 2005, documents CORALs progress toward implementing high-quality and consistent literacy programming. The report presents early results in terms of youths positive reading gains and describes the program components that appear to have contributed to these gains. It also identifies challenges CORAL sites faced and successful strategies for addressing those challenges

Effects of Velocity-Dependent Dark Matter Annihilation on the Energy Spectrum of the Extragalactic Gamma-ray Background

We calculate the effects of velocity-dependent dark matter annihilation cross sections on the intensity of the extragalactic gamma-ray background. Our formalism does not assume a locally thermal distribution of dark matter particles in phase space, and is valid for arbitrary velocity-dependent annihilation. As concrete examples, we calculate the effects of p-wave annihilation (with the $v$-weighted cross section of $\sigma v=a+bv^2$) on the mean intensity of extragalactic gamma rays produced in cosmological dark matter halos. This velocity variation makes the shape of the energy spectrum harder, but this change in the shape is too small to see unless b/a\agt 10^6. While we find no such models in the parameter space of the Minimal Supersymmetric Standard Model (MSSM), we show that it is possible to find b/a\agt 10^6 in the extension MSSM$\otimes U(1)_{B-L}$. However, we find that the most dominant effect of the p-wave annihilation is the suppression of the amplitude of the gamma-ray background. A non-zero $b$ at the dark matter freeze-out epoch requires a smaller value of $a$ in order for the relic density constraint to be satisfied, suppressing the amplitude by a factor as low as $10^{-6}$ for a thermal relic. Non-thermal relics will have weaker amplitude suppression. As another velocity-dependent effect, we calculate the spectrum for s-wave annihilation into fermions enhanced by the attractive Sommerfeld effect. Resonances associated with this effect result in significantly enhanced intensities, with a slightly softer energy spectrum.Comment: 18 pages, 10 figure
