University of Missouri-Columbia 2005.Dissertations, Academic -- University of Missouri--Columbia -- Rural sociology.This research has argued that large scale social forces can influence individual level decisions, such as the decision to leave high school before graduating. The influence of Globalization, via economic restructuring, as measured by the transition from a manufacturing based economy to an economy of services and information, was found to influence students' decisions to drop out. Structural equation models were used to analyze the rural trends taking place from a rural-regional state-wide level. Findings indicated that increases in symbolic analyst and in-person service employment decreased high school dropout rates and the increase in routine production employment increased the dropout rate. Changes in all three occupation categories affected student family characteristics during the 1980s. Increases in in-person service employment had the greatest influence on family structure characteristics. Findings regarding student perceptions of education that resulted in increases in school commitment contributed to decline in high school dropout rates while increases in the number of hours students spent working at a part-time job increased the high school dropout rate

Biases in Reanalysis Snowfall Found by Comparing the JULES Land Surface Model to GlobSnow

Snow exerts a strong influence on weather and climate. Accurate representation of snow processes within models is needed to ensure accurate predictions. Snow processes are known to be a weakness of land surface models (LSMs), and studies suggest that more complex snow physics is needed to avoid early melt. In this study the European Space Agency (ESA)'s Global Snow Monitoring for Climate Research (GlobSnow) snow water equivalent and NASA's MOD10C1 snow cover products are used to assess the accuracy of snow processes within the Joint U.K. Land Environment Simulator (JULES). JULES is run offline from a general circulation model and so is driven by meteorological reanalysis datasets: Princeton, Water and Global Change-Global Precipitation Climatology Centre (WATCH-GPCC), and WATCH-Climatic Research Unit (CRU). This reveals that when the model achieves the correct peak accumulation, snow does not melt early. However, generally snow does melt early because peak accumulation is too low. Examination of the meteorological reanalysis data shows that not enough snow falls to achieve observed peak accumulations. Thus, the earlier studies' conclusions may be as a result of weaknesses in the driving data, rather than in model snow processes. These reanalysis products bias correct precipitation using observed gauge data with an undercatch correction, overriding the benefit of any other datasets used in their creation. This paper argues that using gauge data to bias-correct reanalysis data is not appropriate for snow-affected regions during winter and can lead to confusion when evaluating model processes

‘It’s not about disability, I want to win as many medals as possible’: The social construction of disability in high-performance coaching.

This article draws on the theoretical concepts of Pierre Bourdieu to provide a critical analysis of the social construction of disability in high-performance sport coaching. Data were generated using a qualitative cross-case comparative methodology, comprising 18 months of ethnographic fieldwork in high-performance disability sport, and interviews with coaches and athletes from a cross-section of Paralympic sports. We discuss how in both cases ‘disability’ was assimilated into the ‘performance logic’ of the sporting field as a means of maximising symbolic capital. Furthermore, coaches were socialised into a prevailing legitimate culture in elite disability sport that was reflective of ableist, performance-focused and normative ideologies about disability. In this article we unpack the assumptions that underpin coaching in disability sport, and by extension use sport as a lens to problematise the construction of disability in specific social formations across coaching cultures. In so doing, we raise critical questions about the interrelation of disability and sport

Geologic and mineral and water resources investigations in western Colorado, using Skylab EREP data

The author has identified the following significant results. Skylab photographs are superior to ERTS images for photogeologic interpretation, primarily because of improved resolution. Lithologic contacts can be detected consistently better on Skylab S190A photos than on ERTS images. Color photos are best; red and green band photos are somewhat better than color-infrared photos; infrared band photos are worst. All major geologic structures can be recognized on Skylab imagery. Large folds, even those with very gentle flexures, can be mapped accurately and with confidence. Bedding attitudes of only a few degrees are recognized; vertical exaggeration factor is about 2.5X. Mineral deposits in central Colorado may be indicated on Skylab photos by lineaments and color anomalies, but positive identification of these features is not possible. S190A stereo color photography is adequate for defining drainage divides that in turn define the boundaries and distribution of ground water recharge and discharge areas within a basin

Wingless Flight: The Lifting Body Story

Wingless Flight tells the story of the most unusual flying machines ever flown, the lifting bodies. It is my story about my friends and colleagues who committed a significant part of their lives in the 1960s and 1970s to prove that the concept was a viable one for use in spacecraft of the future. This story, filled with drama and adventure, is about the twelve-year period from 1963 to 1975 in which eight different lifting-body configurations flew. It is appropriate for me to write the story, since I was the engineer who first presented the idea of flight-testing the concept to others at the NASA Flight Research Center. Over those twelve years, I experienced the story as it unfolded day by day at that remote NASA facility northeast of los Angeles in the bleak Mojave Desert. Benefits from this effort immediately influenced the design and operational concepts of the winged NASA Shuttle Orbiter. However, the full benefits would not be realized until the 1990s when new spacecraft such as the X-33 and X-38 would fully employ the lifting-body concept. A lifting body is basically a wingless vehicle that flies due to the lift generated by the shape of its fuselage. Although both a lifting reentry vehicle and a ballistic capsule had been considered as options during the early stages of NASA's space program, NASA initially opted to go with the capsule. A number of individuals were not content to close the book on the lifting-body concept. Researchers including Alfred Eggers at the NASA Ames Research Center conducted early wind-tunnel experiments, finding that half of a rounded nose-cone shape that was flat on top and rounded on the bottom could generate a lift-to-drag ratio of about 1.5 to 1. Eggers' preliminary design sketch later resembled the basic M2 lifting-body design. At the NASA Langley Research Center, other researchers toyed with their own lifting-body shapes. Meanwhile, some of us aircraft-oriented researchers at the, NASA Flight Research Center at Edwards Air Force Base (AFB) in California were experiencing our own fascination with the lifting-body concept. A model-aircraft builder and private pilot on my own time, I found the lifting-body idea intriguing. I built a model based on Eggers' design, tested it repeatedly, made modifications in its control and balance characteristics along the way, then eventually presented the concept to others at the Center, using a film of its flights that my wife, Donna and I had made with our 8-mm home camera
