Understanding Persistent Food Insecurity: A Paradox of Place and Circumstance

Survey data from a USDA-funded multi-state longitudinal project revealed a paradox where rural low-income families from states considered prosperous were persistently more food insecure than similar families from less prosperous states. An examination of quantitative and qualitative data found that families in the food insecure states were more likely to experience greater material hardship and incur greater housing costs than families in the food secure states. Families in the food insecure states, however, did not have lower per capita median incomes or lower life satisfaction than those in the food secure states. A wide range of strategies to cope with food insecurity reported by families in both food insecure and food secure states was examined using the Family Ecological Systems Theory. Families in the food insecure states used several risky consumption reduction strategies such as curbing their appetite and using triage. Families in the food secure states, on the other hand, employed positive techniques involving their human capital.persistent food insecurity, rural low-income families, food coping strategies, Family Ecological systems, material hardship

Comparison of flight-measured and calculated temperatures on the space shuttle orbiter

Structural temperatures and thermal protection system surface temperatures were measured on the space shuttle during the flight of STS 5. The measured data are compared with values calculated at wing stations 134, 240, and 328 and at fuselage station 877. The theoretical temperatures were calculated using the structural performance and resizing finite element thermal analysis program. The comparisons show that the calculated temperatures are, generally, in good agreement with the measured data

A Technique for Transient Thermal Testing of Thick Structures

A new open-loop heat flux control technique has been developed to conduct transient thermal testing of thick, thermally-conductive aerospace structures. This technique uses calibration of the radiant heater system power level as a function of heat flux, predicted aerodynamic heat flux, and the properties of an instrumented test article. An iterative process was used to generate open-loop heater power profiles prior to each transient thermal test. Differences between the measured and predicted surface temperatures were used to refine the heater power level command profiles through the iteration process. This iteration process has reduced the effects of environmental and test system design factors, which are normally compensated for by closed-loop temperature control, to acceptable levels. The final revised heater power profiles resulted in measured temperature time histories which deviated less than 25 F from the predicted surface temperatures

An Efficient Paradigm for Genetic Epidemiology Cohort Creation

Development of novel methodologies to efficiently create large genetic epidemiology cohorts is needed. Here we describe a rapid, precise and cost-efficient method for collection of DNA from cases previously experiencing an osteoporotic fracture by identifying cases using and administrative health-care databases. Over the course of 14 months we collected DNA from 1,130 women experiencing an osteoporotic fracture, at a cost of $54 per sample. This cohort is among the larger DNA osteoporotic fracture collections in the world. The novel method described addresses a major unmet health care research need and is widely applicable to any disease that can be identified accurately through administrative data

MOBILITY21: Strategic Investments for Transportation Infrastructure & Technology

America's transportation infrastructure is the backbone of our economy. A strong infrastructure means a strong America - an America that competes globally, supports local and regional economic development, and creates jobs. Strategic investments in our transportation infrastructure are vital to our national security, economic growth, transportation safety and our technology leadership. This document outlines critical needs for our transportation infrastructure, identifies new technology drivers and proposes strategic investments for safe and efficient air, ground, rail and marine mobility of people and goods.Comment: A Computing Community Consortium (CCC) white paper, 4 page

Washington Legislation—1941

In undertaking to survey the work of the 1941 legislature the aim has not been to attain complete coverage. Space limitations and the time factor have dictated that only certain phases be considered and that brevity rather than complete analysis be the guide. In selecting topics for discussion the aim has been to give attention to those statutes which are likely to be of greatest concern to practicing lawyers. At the outset this meant that virtually all of the largest group of statutes, those dealing with the powers of governmental units, be eliminated. Of the remaining statutes all could not be discussed, or even mentioned, and while the selection has been arbitrary the attempt has been to focus upon those which appear to be of the most general interest. Special regard has been had for statutes affecting judicial procedure, to those of a regulatory character and to social legislation. Because of space and time limitations consideration of some material has necessarily been postponed until the next issue of the Review. Among the statutes which will be discussed in the later issue are those dealing with agriculture, banking, small loans, taxation, trusts, and workmen\u27s compensation. The survey has been a cooperative enterprise by the members of the law faculty of the University of Washington, with the valuable help of members of the student editorial board of the Review. In particular, Dean Falknor was assisted by Mr. Arthur Quigley. Mr. Robert Buck aided Professor O\u27Bryan. Professor Shattuck had the assistance of Mr. Herbert Droker, and Professor Sholley, of Mr. Snyder Jed King and Mr. Bayard Crutcher

The SAMI Galaxy Survey: Unveiling the nature of kinematically offset active galactic nuclei

We have observed two kinematically offset active galactic nuclei (AGN), whose ionised gas is at a different line-of-sight velocity to their host galaxies, with the SAMI integral field spectrograph (IFS). One of the galaxies shows gas kinematics very different to the stellar kinematics, indicating a recent merger or accretion event. We demonstrate that the star formation associated with this event was triggered within the last 100 Myr. The other galaxy shows simple disc rotation in both gas and stellar kinematics, aligned with each other, but in the central region has signatures of an outflow driven by the AGN. Other than the outflow, neither galaxy shows any discontinuity in the ionised gas kinematics at the galaxy's centre. We conclude that in these two cases there is no direct evidence of the AGN being in a supermassive black hole binary system. Our study demonstrates that selecting kinematically offset AGN from single-fibre spectroscopy provides, by definition, samples of kinematically peculiar objects, but IFS or other data are required to determine their true nature.Comment: MNRAS accepted. 14 pages, 11 figure

Perceptions about prenatal care: views of urban vulnerable groups

BACKGROUND: In the United States, infant mortality rates remain more than twice as high for African Americans as compared to other racial groups. Lack of adherence to prenatal care schedules in vulnerable, hard to reach, urban, poor women is associated with high infant mortality, particularly for women who abuse substances, are homeless, or live in communities having high poverty and high infant mortality. This issue is of concern to the women, their partners, and members of their communities. Because they are not part of the system, these womens' views are often not included in other studies. METHODS: This qualitative study used focus groups with four distinct categories of people, to collect observations about prenatal care from various perspectives. The 169 subjects included homeless women; women with current or history of substance abuse; significant others of homeless women; and residents of a community with high infant mortality and poverty indices, and low incidence of adequate prenatal care. A process of coding and recoding using Ethnograph and counting ensured reliability and validity of the process of theme identification. RESULTS: Barriers and motivators to prenatal care were identified in focus groups. Pervasive issues identified were drug lifestyle, negative attitudes of health care providers and staff, and non-inclusion of male partners in the prenatal experience. CONCLUSIONS: Designing prenatal care relevant to vulnerable women in urban communities takes creativity, thoughtfulness, and sensitivity. System changes recommended include increased attention to substance abuse treatment/prenatal care interaction, focus on provider/staff attitudes, and commitment to inclusion of male partners
