State and Local Prevalence of Firearms Ownership: Measurement, Structure, and Trends

Of the readily computed proxies for the prevalence of gun ownership, one, the percentage of suicides committed with a gun, performs consistently better than the others in cross-section comparisons. It is readily computed for states and counties and has a high degree of validity when tested against survey-based estimates. It also appears valid as a proxy for changes over time in gun prevalence, at least at the regional level. Our analysis of this proxy measure for the period 1979-1997 demonstrates that the geographic structure of gun ownership has been highly stable. That structure is closely linked to rural tradition. There is, however, some tendency toward homogenization over this period, with high-prevalence states trending down and low-prevalence states trending up.

Child Care Feeding Programs Support Young Children's Healthy Development

New research by Children's HealthWatch shows that toddlers from low-income families who receive meals from their child care provider - those likely to be receiving CACFP - are in better health, have decreased risk for hospitalization, and are at healthier heights and weights for their age than those whose have to bring meals from home. As the nation's only nutrition program for young children in child care, CACFP is a critical component of a comprehensive approach to child nutrition.Changes to CACFP that expand access, reduce barriers and ensure that child care providers have the resources they need to provide healthy meals are beneficial for young children's health, growth and development

Boost to SNAP Benefits Protected Young Children's Health

The Great Recession has taken a significant toll on America's children. In 2010, 25 percent of children under age six were living in poverty, up from 21 percent in 2007

LIHEAP Stabilizes Family Housing and Protects Children's Health

The heating and cooling season presents special challenges for our nation's low-income families. With limited resources, many are challenged to manage the seasonal spike in utility expenses, facing decisions about whether to pay the rent, keep the lights and heat on, or buy enough groceries to get through the end of the month. We know that each of these decisions will have significant implications for the health of their youngest children. Unfortunately, these tough choices are all too common this winter as the nation experiences increases in energy prices, unusually cold weather, and continued high unemployment

Too Many Hurdles: Barriers to Receiving SNAP Put Childrens Health at Risk

Summary of Findings

Earning More, Receiving Less: Loss of Benefits and Child Hunger

New research from Children's HealthWatch shows that increases in income that trigger loss of public assistance benefits can leave young children without enough food to eat. Families hat have been cut off from SNAP or TANF when their income exceeds eligibility limits are more likely to experience levels of food insecurity that require reducing the size or frequency of children's meals compared to those currently receiving benefits. Previous research has demonstrated that both SNAP and TANF reduce the likelihood of food insecurity. Income eligibility guidelines should be re-examined to ensure that a modest increase in income does not disqulaify a family from the benefits they need to keep their children healthy and well-fed. Families that successfully increase their earnings should not find themselves worse off due to a resulting loss of benefits

Children of Immigrants: Healthy Beginnings Derailed by Food Insecurity

Children of immigrants are the fastest growing child population in the United States. More than 20 percent of children under age six have immigrant parents; approximately 93 percent of these children are American citizens.Of the children who are non-citizens, two-thirds will grow up to become citizens, playing a critical role in our nation's future

Ray Casting Architectures for Volume Visualization

Real-time visualization of large volume datasets demands high performance computation, pushing the storage, processing, and data communication requirements to the limits of current technology. General purpose parallel processors have been used to visualize moderate size datasets at interactive frame rates; however, the cost and size of these supercomputers inhibits the widespread use for real-time visualization. This paper surveys several special purpose architectures that seek to render volumes at interactive rates. These specialized visualization accelerators have cost, performance, and size advantages over parallel processors. All architectures implement ray casting using parallel and pipelined hardware. We introduce a new metric that normalizes performance to compare these architectures. The architectures included in this survey are VOGUE, VIRIM, Array Based Ray Casting, EM-Cube, and VIZARD II. We also discuss future applications of special purpose accelerators.Engineering and Applied Science

Predictors and outcomes of sustained, intermittent or never achieving remission in patients with recent onset inflammatory polyarthritis:Results from the Norfolk Arthritis Register

Objectives: Early remission is the current treatment strategy for patients with inflammatory polyarthritis (IP) and RA. Our objective was to identify baseline factors associated with achieving remission: sustained (SR), intermittent (IR) or never (NR) over a 5-year period in patients with early IP.  Methods: Clinical and demographic data of patients with IP recruited to the Norfolk Arthritis Register (NOAR) were obtained at baseline and years 1, 2, 3 and 5. Remission was defined as no tender or swollen joints (out of 51). Patients were classified as NR or PR, respectively, if they were in remission at: no assessment or ⩾3 consecutive assessments after baseline, and IR otherwise. Ordinal regression and a random effects model, respectively, were used to examine the association between baseline factors, remission group and HAQ scores over time.  Results: A total of 868 patients (66% female) were included. Of these, 54%, 34% and 12% achieved NR, IR and SR, respectively. In multivariate analysis, female sex (odds ratio, OR 0.47, 95% CI: 0.35, 0.63), higher tender joint count (OR = 0.94, 95% CI: 0.93, 0.96), higher HAQ (OR = 0.59, 95% CI: 0.48, 0.74), being obese (OR = 0.70, 95% CI: 0.50, 0.99), hypertensive (OR = 0.67, 95% CI: 0.50, 0.90) or depressed (OR = 0.74, 95% CI: 0.55, 1.00) at baseline were independent predictors of being in a lower remission group. IR and SR were associated with lower HAQ scores over time and lower DAS28 at year 5.  Conclusion: Women with higher tender joint count and disability at baseline, depression, obesity and hypertension were less likely to achieve remission. This information could help when stratifying patients for more aggressive therapy

WIC Improves Child Health and School Readiness

New research by Children's HealthWatch demonstrates that young children who participate in the Special Supplemental Nutrition program for Women, Infants, and Children (WIC) are more likely to be in excellent or good health and have a reduced risk of developmental delay. Investing in WIC supports the nutritional and health needs of young children during a critical window of brain and body growth.Progam improvements that decrease access barriers, provide the full amount of fruits and vegetables recommended by the Institute of Medicine, and accommodate working parents' schedules will help young children reach their full potential
