Preliminary Study of the Homeless in Omaha-Douglas County

Homelessness is not a new phenomenon. The period between the Civil War and World War I, for example, witnessed a large increase in predominantly male transients who followed an active labor market and formed a highly visible subcommunity called skid row. Today\u27s homeless population, however, includes more women, children, and minorities and fewer single men and drifters than previous populations. In addition to changes in the demographic composition of the homeless population, most experts agree that the problem of homelessness is increasing

Nebraska Policy Choices: 1986

The purpose of the Nebraska Policy Choices series is to improve the basis for making state policy choices. This series tries to enhance Nebraskans\u27 awareness of their many alternatives for steering Nebraska into the future. Each annual volume in the series will provide a forum for considering the major issues facing the state and for identifying the various policy options or choices available to Nebraskans. The goals are to broaden public understanding and to promote informed and responsible choices among alternative policies

Management Training Needs Assessment United Methodist Community Centers

This report outlines a management training plan for the United Methodist Community Centers, Inc. (UMCC). UMCC is a community service agency which focuses on bringing positive change for minorities and other disadvantaged people in the Omaha community. UMCC is one of Omaha\u27s major community service agencies and has two locations, the Wesley House in north Omaha and the Woodson Center in south Omaha. A broad range of community programs are coordinated and managed from these two centers, including, for example: family enhancement programs, a woman\u27s resource center, sweat equity housing development, senior meals programs, pre-school and after-school learning programs, and a variety of other youth activities

Development of a Robust and Efficient Parallel Solver for Unsteady Turbomachinery Flows

The traditional design and analysis practice for advanced propulsion systems relies heavily on expensive full-scale prototype development and testing. Over the past decade, use of high-fidelity analysis and design tools such as CFD early in the product development cycle has been identified as one way to alleviate testing costs and to develop these devices better, faster and cheaper. In the design of advanced propulsion systems, CFD plays a major role in defining the required performance over the entire flight regime, as well as in testing the sensitivity of the design to the different modes of operation. Increased emphasis is being placed on developing and applying CFD models to simulate the flow field environments and performance of advanced propulsion systems. This necessitates the development of next generation computational tools which can be used effectively and reliably in a design environment. The turbomachinery simulation capability presented here is being developed in a computational tool called Loci-STREAM [1]. It integrates proven numerical methods for generalized grids and state-of-the-art physical models in a novel rule-based programming framework called Loci [2] which allows: (a) seamless integration of multidisciplinary physics in a unified manner, and (b) automatic handling of massively parallel computing. The objective is to be able to routinely simulate problems involving complex geometries requiring large unstructured grids and complex multidisciplinary physics. An immediate application of interest is simulation of unsteady flows in rocket turbopumps, particularly in cryogenic liquid rocket engines. The key components of the overall methodology presented in this paper are the following: (a) high fidelity unsteady simulation capability based on Detached Eddy Simulation (DES) in conjunction with second-order temporal discretization, (b) compliance with Geometric Conservation Law (GCL) in order to maintain conservative property on moving meshes for second-order time-stepping scheme, (c) a novel cloud-of-points interpolation method (based on a fast parallel kd-tree search algorithm) for interfaces between turbomachinery components in relative motion which is demonstrated to be highly scalable, and (d) demonstrated accuracy and parallel scalability on large grids (approx 250 million cells) in full turbomachinery geometries

Health Care for the Poor in Omaha-Douglas County: Problems and Policy Options

The health-care system in Omaha-Douglas County is on the verge of dramatic changes because of federal cutbacks, expanding cost-containment efforts, and an increasingly competitive medical market. As a result, problems are now arising because of increasing difficulties in providing health care to the poor

PROMIS Physical Function Scale Bookmarking and Validation

• Quick, valid and responsive outcome measure are critical for physical therapists • The NIH’s Patient Reported Outcomes Measurement Information System (PROMIS) is a universal, 124 item, computer adapted system (CAT) that evaluates various health domains including physical function without a ceiling or floor effect. • PROMIS demonstrates good convergent validity with the Health Assessment Questionnaire Disability Index (HAQ-DI) and Short-form 36 (SF-36) physical function subscale1 and also with ‘gold standard\u27 International Knee Documentation Committee (IKDC) scale. PROMIS score can also predict poor outcomes at various follow-up lengths ranging from 3-52 weeks2. • The modified physical performance test (mPPT) is a performance-based test containing several functional tasks and is used to assess physical frailty in older individuals3. • Patient reported outcomes (PRO) require less time and equipment compared to performance based measures. • Purpose: To evaluate the relationship between scores on mPPT and PROMIS. Additionally, to map-out the scoring system of the PROMIS, to allow therapists to utilize it’s T-score in clinical practice

Optimization of a continuous hot embossing process for fabrication of micropyramid structures in thermoplastic sheets

Reported is the manufacture and optimization of inverted micropyramid cavity structures into thermoplastic sheets using roll-to-roll (R2R) embossing. To manufacture the master, an ultraprecision diamond machining method was applied to create seamless surface structures into a copper-coated hot embossing roller. Using the hot embossing process, the roller features were successfully transferred to 2 mm thick polymethyl methacrylate (PMMA) sheets. Optimization of the R2R control process variables was conducted using Taguchi's numerical methods, which showed the importance of the roller temperature for a successful pattern transfer. The work presents a novel fabrication technique that allows microstructures to be manufactured into thick PMMA sheets in a continuous process
