Data Note: Relationship Between Integrated Employment and State Unemployment Rates for MR/DD Consumers

State mental retardation/developmental disability (MR/DD) agencies provided day and employment supports to over 466,500 people in 2001. Approximately 23% of individuals supported by MR/DD agencies nationwide were employed in integrated employment settings, with individual state outcomes ranging from 2% to 56%

Data Note: Relationship Between SSI Recipients Who Work and State Unemployment Rate

The Supplemental Security Income program (SSI) administered by the Social Security Administration provides cash assistance to low-income individuals who are seniors, blind, or have a disability

Data Note: Relationship Between MR/DD Consumers in Integrated Employment and Working SSI Recipients

State mental retardation/developmental disability (MR/DD) agencies provided day and employment supports to over 466,500 people in 2001. Of these, 108,981 individuals were supported in integrated employment settings. The percentage of individuals working in integrated employment varied widely by state, from 56% in Washington to only 2% in Alabama

Data Note: SSA Work Incentives Enrollment, 1990-2004

To encourage employment for individuals with disabilities, the Social Security Administration (SSA) offers special provisions that limit the impact of work on Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI) benefits. These provisions are called work incentives and include the Plan to Achieve Self-Support (PASS), Impairment-Related Work Expenses (IRWE), and Blind Work Expenses (BWE)

Research to Practice: Trends and Emerging Issues Regarding SSA/VR Reimbursements for SSI/SSDI Recipients

This brief discusses the declining amount of reimbursement paid to public VR agencies from federal fiscal year (FFY) 2002 to FFY 2005 by considering the impact that fewer claims submitted and a rising SGA level may have on the amount of reimbursement paid

Data and industrial stormwater general permit benchmarks; what we know

The Port of Tacoma and the Northwest Seaport Alliance are subject to three types of general stormwater management permits. In our quest for improving the water quality of the discharges from our properties, we have collected a large amount of water quality data. We use that data to inform source control and treatment technologies we deploy on our sites. We also share our data and results with tenants to help inform them of their source control and treatment choices based on the actual stormwater chemistry generated by site activities. We also use the data to customize treatment media recipes

Analytic many-body potential for GaAs(001) homoepitaxy: Bulk and surface properties

We employ atomic-scale simulation methods to investigate bulk and surface properties of an analytic Tersoff- Abell type potential for describing interatomic interactions in GaAs. The potential is a modified form of that proposed by Albe and colleagues [Phys. Rev. B 66, 035205 (2002)] in which the cut-off parameters for the As-As interaction have been shortened.With this modification, many bulk properties predicted by the potential for solid GaAs are the same as those in the original potential, but properties of the GaAs(001) surface better match results from first-principles calculations with density-functional theory (DFT). We tested the ability of the potential to reproduce the phonon dispersion and heat capacity of bulk solid GaAs by comparing it to experiment and the overall agreement is good. In the modified potential, the GaAs(001) β2(2 × 4) reconstruction is favored under As-rich growth conditions in agreement with DFT calculations. Additionally, the binding energies and diffusion barriers for a Ga adatom on the β2(2 × 4) reconstruction generally match results from DFT calculations. These studies indicate that the potential is suitable for investigating aspects of GaAs(001) homoepitaxy

Interactions Mediated by Surface States: From Pairs and Trios to Adchains and Ordered Overlayers

Since metallic surface states on (111) noble metals are free-electron like, their propagators can be evaluated analytically. Since they are well-screened, one can use simple tight-binding formalism to study their effects. The needed phase shifts can be extracted from experiment. Hence, one can now make quantitative predictions of these slowly-decaying, oscillatory indirect interactions. For the (isotropic!) pair interactions (which decay as the inverse square of adatom-adatom separation), remarkable agreement has been obtained with experiments by two groups. We have extended the formalism to consider the full indirect ("triple") interaction of 3 adsorbates, which is the sum of the 3 constituent pair interactions plus the non-pairwise "trio" contribution, which tends to decay with the 5/2 power of perimeter. Here, we concentrate on interactions due to ordered overlayers and to linear defects, relating the latter to the interactions of (nx1) ordered overlayers and to the constituent pair interactions. We compare with experimental studies of interactions of adatoms with adchains and of consequent 1D motion of adatoms trapped between two such parallel chains. We discuss implications for step-step interactions (on vicinal surfaces), with attention to the modification of the surface state itself for small terrace widths.Comment: 4 pages, Proceedings of 14th International Conference on Crystal Growth, Grenoble, France, 9-13 August 2004; to be published in J.
