Archaeological inquiry into the landscapes produced by free Black Americans has greatly contributed to understandings of how spatial use continued to reflect resistance to racial subjugation during the Reconstruction and Jim Crow eras. In this article, I discuss the community of Antioch Colony, a freedmen’s community located in central Texas, to consider the remaking of Black community in the rural countryside between the years of 1870 and 1954. Using oral histories, historic aerial photography, and historic maps, I examine the ways residents of Antioch Colony adapted their landscape over time to create an empowering environment suitable for their needs in the post-bellum period. Through my analysis, I find that the landscape created reinforced a sense of belonging by allowing people to freely congregate and move through space.

Wildland and wildland/urban interface fires are a serious problem in many areas of the world. It is expected that with global warming the wildfire and wildland/urban interface fire problem will only intensify. The ignition of natural combustible material by hot metal particles or embers is an important fire ignition pathway by which wildland and urban spot fires are started. There are numerous cases reported of wild fires started by hot metal particles from clashing power lines, or from sparks generated by machines or engines. Similarly there are many cases reported of industrial fires caused by grinding and welding sparks. Despite the importance of the subject, the topic remains relatively unstudied. The senior author of this article and his collaborators have been working for the past few years on this problem. In this article, we provide a comprehensive summary of that work to date. The work includes experimental and theoretical modeling of the ability of hot metal particles and embers to cause the ign...

Study objective. To compare the amount of segmental vertebral motion produced with the lateral recovery position and the HAINES technique when performed on cadavers with destabilized cervical spines. Methods. The cervical spines of 10 cadavers were surgically destabilized at the C5–C6 vertebral segment. Sensors from an electromagnetic tracking device were affixed to the vertebrae in question to monitor the amount of anterior/posterior, medial/lateral, and distraction/compression linear motion produced during the application of the two study techniques. Results. The statistical analysis of linear motion data did not reveal any significant differences between the two recovery positions. Conclusion. At this time, no single version of the recovery position can be endorsed for the spine-injured trauma patient. More research is needed to fully ascertain the safety of commonly used recovery positions.

The American Academy of Pediatrics and the American Academy of Family Physicians believe that infants, children, and adolescents benefit from having a medical home, characterized by accessible, continuous, comprehensive, family-centered, coordinated, compassionate, and culturally effective care. Several studies suggest that patients with asthma benefit from having a medical home. However, no national study has been conducted examining the relationships between having a medical home and asthma control in school-aged children with asthma. The purpose of this study was to examine the hypothesis that having an adequate medical home is protective against uncontrolled asthma in children.To test this hypothesis, cross-sectional data from the 2003-2004 National Survey of Children's Health were analyzed. Analyses entailed creating the variables "medical home" as well as "uncontrolled asthma" from multiple variables. Multivariate analysis was performed using children with uncontrolled asthma as the dependent variable.The logistic regression model performed yielded that school-aged children with uncontrolled asthma were more likely to: speak a primary language other than English (OR, 1.069; 95% CI, 1.045-1.093); live in households with incomes100% of the federal poverty level (FPL) (OR, 1.826; 95% CI, 1.810-1.842); not have health insurance (OR, 2.296; 95% CI, 2.263-2.330); live in rural rather than metropolitan areas (OR, 1.275; 95% CI, 1.262-1.287); and be non-Caucasian (OR, 2.067; 95% CI, 2.050-2.085). Multivariate analysis also yielded that children with uncontrolled asthma were more likely to have a medical home (OR, 1.138; 95% CI, 1.128-1.148).After controlling for possible confounding variables, this study did not detect an association between having a medical home and asthma control for children with asthma aged 5 to 17 years. Additional research should examine the relationship between variables, such as poverty, place of residence, health insurance status, and the medical home, not only in the instance of uncontrolled asthma, but for other childhood health conditions.
