Estimation Of Water Surface Elevation Probabilities And Associated Damages For The Great Salt Lake, L. Douglas James, David S. Bowles, W. Robert James, Ronald V. Canfield

Reports

Rising water surface elevations in perennial terminal lakes threaten major damages to shoreline industrial plants, transportation routs, and wetlands. Falling elevations increase pumping costs for industries extracting minerals from the lake water and reduce the quality of shoreline recreation. The managers of these properties need information on future lake level probabilities for planning, and public agencies need information on both probabilities and damages to determine whether lake level control is justified. Standard methods for estimating flood frequency and damages in riverine areas do not work well for terminal lakes because of the interdependency in annual peaks and the long advanced …

An Economic Evaluation Of The Salinity Impacts From Energy Development: The Case Of The Upper Colorado River Basin, Rangesan Narayanan, Sumol Padungchai, A. Bruce Bishop

Reports

To analyze the effect of potential energy development on water allocation and water quality in the Upper Colorado River Basin, a linear programming model is formulated. Using the model, changes in salinity are predicted. Further, least-cost strategies to maintain the established numeric salinity criteria through both structural and nonstructural alternatives are developed. The effectiveness of alternative control measures are examined within given institutional constraints. Based on cost-benefit analysis, optimal salinity levels over time are proposed. The economic feasibility of presently planned strucutral measures to reduce salinity is investigated and contrasted with nonstructural alternatives.

Since nearly every water resource managment choice has two or more sides, differences must be resolved in decision making. Equitable resolution requires an understanding of the reasons for the differences. These reasons originate in the implemented plans have physical-environmental, economic, social, cultural, and political impacts at levels ranging from local to national or international in scope. Decisions are made by individuals and groups impacted in all of these dimensions and at all of these levels; the decisions generate additional impacts; and the entire interactive process changes water management practice in ways outside the control of any one decision point or …

Erosion Control During Highway Construction: Volume 1, Calvin G. Clyde, C. Earl Israelsen, Paul E. Packer

Reports

Summary: Highway constuction as we know it today is a high-risk activity with respect to engendering soil erosion. In earlier days of road building, when rights-of-way were generally narrow and excavations mostly shollow, erosion was rarely a serious problem. Only occasionally was it considered necessary to design and apply specific measures for erosion control. With the advent of the superhighway involving far greater widths of right-of-way, and much deeper disturbance of the natural ground to affort the horizontal and vertical highway geometry necessary for high-speed travel, came a several fold increase in erosion potential and a direct need for specific …

Local Consequences Of Reclamation Overkill, Allen Lebaron, Keith Wilde

Economic Research Institute Study Papers

A nine-year intermittent study of promotion grouf records, planning and operational documents, plus dozens of conversations with "watermen" familiar with the Weber Basin Project, Utah, has led us to conclude that considerable mis-allocation of scarce resources has occurred. Expensive, planned reclamation features have been a complete failure; a great regional imbalance in benefits and costs exists; development of a continuously recharged under ground aquifer could have been made at a fraction of the surface feature cost. The fact that the project is in no financial difficulty is beside the point, the truth is that a lot of unnecessary costs must …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Conflicting data have been reported concerning the effects of reinforcement procedures on the intelligence test-taking behavior of normal children. Additionally, no adequately designed study to date has examined the possibility that sex may be a variable in determining childrens' response to intelligence tests administered under reinforcement conditions. The present study was designed to determine if the scores of children administered two tests, the Wechsler Intelligence vi Scale for Children (WISC) and the Peabody Picture Vocabulary Test (PPVT), would be differentially affected by reinforcement procedures incorporated into the administration procedures. Additionally, it was designed to determine if sex of the children …

A Discriminant Function Model Of Gray-Headed Junco Habitat, Andrew R. Grainger

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This paper presents a description of gray-headed junco habitat in the form of a model based on discriminant function analysis. Junco nests were found by searching randomly located grids on a 7.8 km² study area in central Utah. Vegetation data was gathered on 500 m² circular plots surrounding nests and contrasted with similar data from searched grids where nests were not found. The model explains 28 percent of the between-groups variance and correctly classifies 68 percent of the plots.

Plant cover types are good predictors of areas where gray-headed juncos nest, while plant community type descriptions do not …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Natural hazards have been an increasing problem in wildland recreation areas. This study attempted to identify factors affecting park visitor perception of and preparedness for hazards.

A model was formulated incorporating three major independent variables which might affect park visitor responses to hazards. These were: (1) previous experience, (2) information about hazards provided by the park administration (such as warnings located on signs or in brochures), and (3) visitor perception of whether responsibility for hazards rests with the individual or with an outside authority such as government or God. Trip length and knowledge of hazards were also thought to be …

Linguistic Surface Structure In Family Interaction, Thomas D. Macroy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this dissertation was to determine the usefulness of the linguistic processes of Distortion, Deletion, Generalization, and Semantic Ill-Formedness as constructs which differentiate the verbal communication of families who express dissatisfaction with their current intrafamilial relationships from families expressing satisfaction with their current relationships. Specifically, it was hypothesized that dissatisfied families would use these linguistic structures to a greater extent in their interaction than would satisfied families.

Thirty-one family triads (father, mother, and child) were obtained by asking families randomly selected from the local high school student directory to participate. The families were given a Revealed Differences questionnaire …

Coordination Chemistry Of Bidentate Difluorophosphines, Darrell Lynn Gallup

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The reactions of 1, 2–bis(difluorophosphino)cyclohexane, PF₂C₆H₁₀PF₂, with hexacarbonyls of Cr(O), Mo(O), and W(O) have been extensively investigated. The hexacarbonyls react, either under photolytic or thermolytic conditions, to produce carbon monoxide and oily mixtures of products of the general formulations, [M(CO)₄(PF₂C₆H₁₀PF₂C)]_x, where x varies apparently from 1 – 4. The higher values of x, corresponding to species involving bridging ligands, are more common to the photolysis rather than the thermolysis reactions. Photolysis reactions of Mo(Co)₆ with increasing amounts of the …

Multicollinearity And The Estimation Of Regression Coefficients, John Charles Teed

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The precision of the estimates of the regression coefficients in a regression analysis is affected by multicollinearity. The effect of certain factors on multicollinearity and the estimates was studied. The response variables were the standard error of the regression coefficients and a standarized statistic that measures the deviation of the regression coefficient from the population parameter.

The estimates are not influenced by any one factor in particular, but rather some combination of factors. The larger the sample size, the better the precision of the estimates no matter how "bad" the other factors may be.

The standard error of the regression …

Magnesium Deficiency And Excitability In The Rat: An Examination Of Selected Biochemical And Physiological Events Relating Magnesium Status To Behavior, Douglas Robinson Buck

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effect of Mg status on the behavior of rats, as determined by nonspecific excitability level and audiogenic seizure susceptibility, was investigated. Also, selected biochemical and neurological mechanisms mediating the chain of events from dietary magnesium deficit to the hyperexcitability symptoms were examined. Weanling rats fed a low magnesium (10 ppm) diet for 14 days had reduced serum, cerebrospinal fluid and brain magnesium concentrations, and increased brain (Na⁺ K⁺) -ATPase activity. They exhibited increased NEL and became highly susceptible to audiogenic seizures. Through dietary manipulation and intraperitoneal and cerebral intraventricular injections, it was possible selectively to alter …

Quantitation Of Formaldehyde Resulting From Oxidative Deterioration Of Unsaturated Fatty Acids, Stanley J. Andrews

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Derivatives of 3-methyl-1-2-benzothiazolinone hydrazone were formed from the oxidation products of three oxidized unsaturated fatty acids. Aeration with oxygen and heat (65C) was used as a means of accelerating deterioration of lipid samples. Formaldehyde was recovered from oxidized pure standards of oleic, linoleic and linolenic acid methyl esters, and identified using gas chromatography. Formaldehyde was also recovered from oxidized lipid extracts of mechanic ally deboned turkey meat and turkey cluster fat. Gas chromatography was used to measure concentrations of unsaturated fatty acids during the oxidation of extracted lipids. Linoleic and linolenic fatty acids significantly decreased (p < .005) in oxidized lipid extracts from turkey cluster fat stored frozen for six months.
