Evaluating the impact of National Park Service landscape preservation policies on archaeological site formation : archaeology of the Nevada Camp (42WS4484)

Between 1927 and 1930 the Nevada Contracting Company of Fallon, Nevada constructed the Zion Tunnel and a portion of the Zion-Mt. Carmel Highway in Zion National Park, Utah. During the construction approximately 200 workers lived at the contractor's camp, known today as the Nevada Camp. This camp, a temporary work camp, was dismantled upon completion of the construction project and the site was cleaned to the National Park Service landscape preservation standards. Rules and standards set forth by the National Park Service subjected the Nevada Camp site to a substantial cultural transformation process. Research conducted at the Nevada Camp (site number 42WS4484) determined whether identifiable behavioral patterns existed archaeologically in temporary work camps that have been modified by such a substantial cultural transformation processes and provide a base for evaluating the impact of activities such as site dismantling

"The Dust Was Long In Settling": Human Capital and the Lasting Impact of the American Dust Bowl

I find that childhood exposure to the Dust Bowl, an environmental shock to health and income, adversely impacted later-life human capital—especially when exposure was in utero—increasing poverty and disability rates, and decreasing fertility and college completion rates. The event’s devastation of agriculture, however, had the beneficial effect of increasing high school completion, likely by pushing children who otherwise might have worked on the farm into secondary schooling. Lastly, New Deal spending helped remediate Dust Bowl damage, suggesting that timely and substantial policy interventions can aid in human recovery from natural disasters

Energy transfer reactions in electron beam excited mixtures of xenon and argon gases

The time dependence of the vacuum ultraviolet emissions from mixtures of xenon and argon gases is measured following excitation by a low intensity electron beam. The xenon concentration is varied from 8.4 x 113 cm-3 to 2.76 x 1 cm while the argon density is varied between 5.1 x 1 cm and 2.9 x 1 cm . The second molecular continuum of argon is observed to be quenched in electronic excitation transfer to xenon atoms forming the xenon state with a rate constant of (4.39 - .5) x 1 cm /sec. At the higher xenon concentrations the second molecular continuum of xenon is formed by destruction of xenon atoms in collisions with a ground state xenon atom and a ground state argon atom at the rate of (2.15 -+. 25)-x312 cm /sec. The first molecular continuum of xenon is observed to be collision induced radiation from the xenon P level as well as radiation from high vibrational levels of the Ou molecule of xenon. The collision induced radiation rate constant is found to be (3.2-.7) x 1 cm/sec. The rate of formation of xenon molecules radiating in the first continuum is (2.1+- .2) x 1-31c m6 /sec. Collisional de-excitation of the xenon P^ level occurs with a rate constant of (1.5 +- . 3)-x114 c3m /sec
