Resource Competition Among the Uinta Basin Fremont
Archaeologists describe the Uinta Fremont (A.D. 0 – 1300) as a mixed foraging-farming society that underwent a dramatic social change from A.D. 700 – 1000. Researchers observe through different architectural styles and subsistence activity a change from large, aggregated settlements to more dispersed and defensively oriented villages and hamlets. The Ideal Free Distribution (IFD) model provides an explanatory framework through which to interpret these changes. IFD predicts the order in which people or animals will occupy habitats based on a habitat’s relative suitability and suggests hypothetical behaviors that people or animals might engage in to improve or maintain the relative suitability of a habitat. One prediction of IFD is that behaviors indicating resource competition will become more frequent when population density increases. I test whether this hypothesis explains changes in storage features by considering storage behavior as a manifestation of resource competition, and I investigate whether storage feature frequency correlates with periods of Fremont population increases and paleoenvironmental degradation.
These tests explain aspects of Fremont culture change and suggest future research possibilities. Storage feature frequency, representing resource competition, remains low from A.D. 0 – 700, suggesting that the habitats could absorb growing Fremont populations. After A.D. 700, however, resource competition rose and remained high, a condition that likely spurred the defensive architecture and dispersed settlements that became increasingly common after A.D. 1000. The successes and limitations of applying IFD to the archaeological record point the way toward future uses of the model to investigate settlement spacing and reaffirm the use of radiocarbon data in archaeological science
The spatial ecology of free-ranging domestic pigs (Sus scrofa) in western Kenya
Background
In many parts of the developing world, pigs are kept under low-input systems where they roam freely to scavenge food. These systems allow poor farmers the opportunity to enter into livestock keeping without large capital investments. This, combined with a growing demand for pork, especially in urban areas, has led to an increase in the number of small-holder farmers keeping free range pigs as a commercial enterprise. Despite the benefits which pig production can bring to a household, keeping pigs under a free range system increases the risk of the pig acquiring diseases, either production-limiting or zoonotic in nature. This study used Global Positioning System (GPS) technology to track free range domestic pigs in rural western Kenya, in order to understand their movement patterns and interactions with elements of the peri-domestic environment.
Results
We found that these pigs travel an average of 4,340 m in a 12 hr period and had a mean home range of 10,343 m2 (range 2,937–32,759 m2) within which the core utilisation distribution was found to be 964 m2 (range 246–3,289 m2) with pigs spending on average 47% of their time outside their homestead of origin.
Conclusion
These are the first data available on the home range of domestic pigs kept under a free range system: the data show that pigs in these systems spend much of their time scavenging outside their homesteads, suggesting that these pigs may be exposed to infectious agents over a wide area. Control policies for diseases such as Taenia solium, Trypanosomiasis, Trichinellosis, Toxoplasmosis or African Swine Fever therefore require a community-wide focus and pig farmers require education on the inherent risks of keeping pigs under a free range system. The work presented here will enable future research to incorporate movement data into studies of disease transmission, for example for the understanding of transmission of African Swine Fever between individuals, or in relation to the life-cycle of parasites including Taenia solium
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
Energy Insecurity is a Major Threat to Child Health
With the recession and this winter's harsh weather, many families are facing a choice between eating and heating. Research by Children's HealthWatch shows that young children whose families struggle to pay their utility bills ('energy insecure' families) are more likely to suffer a host of problems including food insecurity, poor health, hospitalizations and developmental delays.The Low Income Home Energy Assistance Program (LIHEAP), which provides low-income households with assistance in paying their utility bills, is effective at shielding young children from the harmful effects of energy insecurity.According to research by Children's HealthWatch, young children whose families received LIHEAP were less likely to be at risk for growth problems and had healthier weights for their age.By appropriating the maximum authorized funding for LIHEAP and ensuring that climate change legislation buffers vulnerable families and children from the harmful effects of higher energy prices, Congress will be taking important steps to protect children's health
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
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
Mass transit
The most embarrassing secrets are usually the most boring. I might, for instance, tell you that I am 39 and like to hum show tunes in the shower and wear briefs and not boxers, but I would never tell you that every Thursday, at precisely seven a.m., I step on to the Number 7 bus at the 100th Street stop and do not get off for hours
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
