STEM PIPELINE FOR STUDENTS WITH DISABILITIES: FROM HIGH SCHOOL TO INTENTIONS TO MAJOR IN STEM

This dissertation examined the science, technology, engineering, and math (STEM) major declaration intentions of students with disabilities as they graduated high school and entered college. I used data from the High School Longitudinal Study of 2009 (HSLS:09) because data collection began in high school and followed students into college, facilitating research focusing on access. Before investigating major declaration intentions, I critiqued the definition and measurement of disability in the HSLS:09, drawing from survey research methods literature. The two subsequent analyses focused on psychological and structural components, respectively. My focus on psychological components drew from Eccles and colleagues’ (1983) expectancy-value framework. This framework tapped into the valuation that students placed on math- and science-related concepts and their expectations to succeed in those fields. Structural components explored in the final analysis drew from human, cultural, and social capital theories. These three theories were at the core of Perna’s (2006) model of college choice, which I adapted to predict majoring in STEM. Both analyses utilized multiple logistic regression to create prediction models. Findings suggested that college-bound students with ADHD have higher odds of intending to pursue STEM majors, compared to students experiencing other forms of disability. Psychological and structural measures were also positively related with odds of pursuing these majors. Implications highlight avenues for enhancing STEM participation for students with disabilities, offer suggestions for improvements to future data collection efforts, and lend guidance for future researchers looking to study disability using the HSLS:09 or other secondary data

Simulation and Analysis of Stream-Aquifer Systems

As defined for this study, a stream-aquifer system is a hydrologic system in which there is an intimate hydraulic interrelationship between one or more aquifers and a perennial stream. The objectives of this study are to better understand the response behavior of typical stream-aquifer systems, to look at the response behavior as influenced by water management practices, and to consider the problems and possibilities of integrated management of groundwater and surface water supplies within stream-aquifer systems. A brief history of water development practices and policy, particularly in the Western United States, indicates that the tendency over the years has been to attempt to improve efficiency of use and increase water availability by means of coordinated management of sources and uses of water within hydrologic units. This tendency is manifested by the concepts of basin planning, multiple purpose projects, and comprehensive planning. Also, history shows that surface and groundwater have typically been developed separately with little regard for the interrelationships between the two. Through the cooperation of the U.S. Geological Survey, major stream-aquifer systems in the Western United States have been identified. The Soil Conservation Service provided information on water management problems, causes, and needs found within the major stream-aquifer systems. Components of stream-aquifer systems are classified into (1) input variables, (2) system parameters, (3) output or system responses. Techniques for modeling stream-aquifer systems are discussed, and the mathematical model technique used is presented. Over 160 stream-aquifer systems were simulated, utilizing mathematical models and digital computer solutions. The response behavior was measured in terms of the change of groundwater levels and the pattern of outflow to the stream. The latter system response is emphasized because of the effect upon other water users which is often not considered when changes are made in water management practices. The influence of such variables and parameters as (1) the total water added to the aquifer, (2) the time distribution of the water added, (3) the areal distribution of the water added, (4) the aquifer hydraulic characteristics, (5) the geometric characteristics of the aquifer, and (6) the initial configuration of the water table surtace are discussed with results presented in tabular and graphical form. The effect of common water management practices (drainage, phreatophyte control, improvement of irrigation efficiency, and lining of canals), along with further water management practices desirable in a fully integrated streamaquifer system are discussed

A Hydrologic Analysis of Government Island, Oregon

Government Island, located in the Columbia River approximately 16 km (10 mi) upstream of the confluence with the Willamette River, is a wetland mitigation site prompted by expansion of the southwest quadrant of Portland International Airport. The purpose of the study is to predict water levels in two enclosed lowland areas, Jewit Lake and Southeast Pond, based on levels of the Columbia River, precipitation, and evapotranspiration. Mitigation is intended to convert 1.13 km2 (237 acres) of seasonally flooded wetland to 1.27 km2 (267 acres) of semi-permanently flooded wetland and seasonally flooded wetland. Flooding of the wetland is most likely to occur December through January and May through early June when Columbia River water levels at Government Island exceed 3.6 m (12 ft) m.s.l. Flooding of Jewit Lake occurs through a channel connecting the wetland to the Columbia River. A groundwater model (MODFLOW) was parameterized to simulate the hydrology of the wetland. Observations of the subsurface stratigraphy in 25 soil pits, bucket auger cores, and during installation of water monitoring devices were used to estimate thickness and lateral extent of a confining unit that overlies an aquifer. Climatological data for 1994 and water levels were entered into MODFLOW to calibrate rates of water movement through the subsurface. Periods of drying for Jewit Lake and Southeast Pond were predicted based on precipitation and actual evapotranspiration rates expected to be present in the study area between June and December. Results of groundwater modeling show that Jewit Lake will maintain surface water above 3.6 m (12 ft) in most years. Southeast Pond is expected to dry annually as mitigation is unlikely to change the hydrology of Southeast Pond. Groundwater modeling predicted the types of wetlands present at different elevations by evaluating periods of drying within the wetland using the U.S. Fish and Wildlife Service classification of wetlands method. Results suggest that Jewit Lake will be converted to semipermanently flooded wetland below 3.6 m (12 ft) in elevation. Southeast Pond will remain a seasonally flooded wetland as a result of mitigation
