Freshman Orientation And Career Articulation With A Rational Value Decision-Making Model, Bud W. Stephenson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The role identity of the college and university counseling center has been in a state of evolution for the past few years and a reconceptualized role for the college and university counselor is beginning to emerge. This evolution is the result of rapid change taking place within society and in higher education. In recent research such authors as Morrill and Oetting (1970) have noted that the programs of counseling centers in the colleges and universities are not changing along with the rest of the college environment today and programs are thus becoming more and more outdated and irrelevant. Along with …

Internal Water Potential Of An Engelmann Spruce Stand In Relation To Soil And Atmospheric Factors, Richard L. Meyn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The primary objective of this study was to determine the degree of correlation between internal water potential of Engelmann spruce trees and selected environmental factors. The secondary objective of the study was to determine the effect of summer precipitation, both in meadow and forested sites, on the soil drying cycle.

Four study plots (each roughly 154 square meters) under spruce cover and two study plots (100 square meters) in a small meadow were established. At each spruce plot, a thermocouple psychrometer was installed at one meter above the ground on the north side of three selected, mature Engelmann spruce trees. …

Trout Movements In A Small Mountain Stream, Thomas Mark Twedt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Five groups of 400 hatchery rainbow trout, (Salmo gairdneri), were stocked in a small, mountain stream at 3-week intervals from June to September, 1972. A fish trap captured any fish moving out of a 500 m study section.

Fish began moving at high levels during the first day of each stocking and continued at high rates for 5-8 days (Early Phase), after which movement decreased to low levels for 6-9 days (Late Phase). Early Phase fish moved primarily at night, possibly due to their disoriented state and high subjectivity to stream conditions. Fish moving during Late Phase did …

Mineral And Chemical Content Of The Deep-Water Sediment Sequences Of Bear Lake, Utah-Idaho, James C. Biesinger

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Twenty-five piston cores 6 to 12 feet long were obtained from the deepwater sediments of Bear Lake, Utah-Idaho. Analyses of these cores revealed that the deep-water sediments of the lake are divided into two major sequences: a younger sequence rich in carbonate minerals, here called the carbonate sequence, and an older sequence rich in silicate minerals, referred to in this paper as the silt sequence. The carbonate sequence is composed of clay-sized quartz, aragonite, calcite, dolomite, montmorillonite, illite, kaolinite, chlorite, and amorphous material. The silt sequence consists of both silt- sized and claysized particles of quartz, calcite, dolomite, montmorillonite, illite, …

A History Of Brigham Young College, Logan, Utah, Arnold K. Garr

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Before Brigham Young College was founded in 1877, a variety of schools existed in Utah. The Mormons at first, and later the Protestants and Catholics made significant contributions to education in the territory.

Education has always played an important role in the philosophy of the Mormon church. In the early days of church history, the Mormons founded schools in the places they settled. This policy continued when they settled in Utah.

The Economic Efficiency Of Inter-Basin Transfers Of Agricultural Water In Utah: A Mathematical Programming Approach, John Keith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The economic efficiency of water development in Utah, including transfer systems, has seldom been examined, nor has the costs of public policies which result in deviations from efficient allocations. In order that public officials be better informed about water allocations, the present effort examines the efficient allocation of water in time frames up to 2020 under several alternative assumptions and calculates the cost of alternative policies.

Using mathematical programming techniques, a computer mode l is developed to determine the supply (marginal cost) and demand (value of marginal product) relationships for agricultural water, given depletions for municipal and industrial (M & …

The Foods And Feeding Habits Of Botulism Intoxicated And Healthy Waterbirds On The Bear River Refuge, Utah With Emphasis On The American Avocet And Blacknecked Stilt, George W. Wilson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Primary objectives of this study were: (1) to compare the food habits of healthy and botulism intoxicated American avocets and blacknecked stilts for qualitative and quantitative differences, (2) to determine which invertebrates found in the tracts of intoxicated and healthy birds contained type C toxin, and (3) to explain apparent susceptibilities among different sexes, ages and species of birds.

Based on percent utilization and occurrence of food items in the esophagus, the diets of healthy and intoxicated birds were similar. However, intoxicated avocets consumed higher proportions of Gastropoda and intoxicated stilts more Hydrophilidae larvae than did healthy birds. Because of …

Habitat Selection By Large Wild Ungulates And Some Aspects Of The Energy Flow In A Sub-Tropical African Savanna Woodland Ecosystem, Stanley M. Hirst

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study of habitat selection by large wild ungulates was carried out on a 50 cm² area in the sub-tropical Lowveld region of eastern Transvaal province, South Africa. Estimations were made of herbaceous forage net productivity and ungulate secondary productivity on the same area.

Fourteen vegetation types, varying in composition and structure from open savanna to dense woodland, were delineated by association analysis. Structural and vegetational characteristics which were considered to influence ungulate distribution were measured within each vegetation type.

The study area supported resident populations of seven ungulate species during the wet season; drv season densities were higher …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two perennial species of wild geranium (Geranium nervosum Rydb. and G. richardsonii Fisch, and Trautv, [Geraniaceae]) which grow throughout the mountainous regions of western North America were studied to determine the factors influencing the life stage development and distribution of these plants. Attempts were also made to provide some information to assist in the taxonomy of this genus.

Geranium richardsonii is found in wet meadows and along streambanks throughout its distribution. Geranium nervosum frequents rocky hillsides and drier meadows throughout its range.

Seeds of G. nervosum had 65%, germination in the stratification pretreatment. Geranium richardsonii seeds required scarification to …

Effects Of Exercise On Serum Lactate Dehydrogenase Activity Of Catchable-Size Hatchery Rainbow Trout, Salmo Gairdneri, Gerlad T. Klar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Effects of exercise and the relative condition of exercised fish were viii evaluated for two strains of rainbow trout. Circular tanks fitted with a paddle were used to continuously exercise the fish and a stamina tunnel was used to evaluate the condition of exercised trout. Trout were exercised continuously at one fish-length per second and one-half fish length per second. Serum LDH activity in Shephard-of-the-Hills (Missouri) rainbow trout acclimated to 10 C increased two fold during the first four days of exercise. Serum LDH activity returned to control levels by the tenth day of exercise. Serum LDH activity in Shephard-of-the-Hills …

Bromegrass Productivity In Relation To Precipitation, Shrub Canopy Cover And Soil Nitrogen Content, Lawrence G. Kline

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In seasons of above normal precipitation, populations of annual weedy species increase in great abundance in semi-arid desert plant communities. These increases in biomass tie up a considerable portion of the available nitrogen of such ecosystems and may depress subsequent annual grass germination.

A big sagebrush-annual bromegrass plant community was irrigated to simulate a spring growth period of abundant precipitation amenable to annual bromegras s productivity. Productivity and nitrogen content parameters were monitored throughout the spring and summer to evaluate the short and potential long term effects of this seasonal increase in "precipitation".

Irrigation increased annual bromegrass productivity almost 50 …

A Comparison Of Consumer's Surplus And Monopoly Revenue Estimates Of Recreational Value For Two Utah Waterfowl Marshes, C. Holden Brink

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Demand curves were estimated for waterfowl hunting and nonconsumptive recreational use from use rate and variable expenditure data collected at the Bear River Migratory Bird Refuge and the Farmington Bay Waterfowl Management Area during fiscal 1969. Consumer's surplus and monopoly revenue estimates were then derived from the demand functions. Adjusted estimates of consumer's surplus for waterfowl hunting amounted to $7,260 per year at Bear River and $11,400 per year at Farmington Bay. For nonconsumptive recreation annual consumer's surplus was estimated to be $18,700 at Bear River and $3,760 at Farmington Bay. Monopoly revenue estimates were between one-half and one-fourth the …

A Measure Of The Amount Of Phosphate Adsorption And The Rate Of Release Of Indigenous Phosphate From A Desert Soil, Robert Lindsey Evans

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The capacity of a calcareous desert soil, Thiokol silt loam, to retain natural, as well as added, orthophosphate-P was measured by equilibrium adsorption employing a batch technique and evaluated using the two-slope Langmuir adsorption isotherm. From these data, corrected to account for indigenous soil P, a hypothesis was formulated as to the nature of retention of P by the soil, including the identification of two interfacial reactions involving P, and a value calculated for the adsorption maximum as defined by the Langmuir isotherm equation for P with soil at each of two soil depths and three constant temperatures within the …

Subjects from the experimental group found to be non-conservers on the Conservation pretest were taught conservation principles using sever al different tasks …

Mesoscale Atmospheric Circulation And Diffusion Characteristics, Ronan I. Ellis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Constant volume superpressure pillow balloons were flown over a mountain valley downwind from a sharp ridge line. Balloon trajectories revealed and atmospheric soundings confirmed a persistent turbulently mixed adiabatic layer over the valley at approximately ridge top height except in the immediate lee of the ridge where strong vertical motions were observed. Temporary stationarity of the relative mesoscale turbulence was found to exist on a time scale exceeding 4 hours. Power spectrum analysis of component relative velocities showed greater variance in lower wave numbers and anisotropy in mesoscale turbulence. Eddy diffusivity coefficients for turbulence above the ridge height were K …

An Intensive Edaphological Characterization Of The Soils Of Malambito Experimental Station And Its Implications In Future Agricultural Research, William L. Rubink

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Malambito Experiment Station, in the Atlántico III project area, Department of Atlántico, Colombia, had almost no quantitative edaphological data on which to base agricultural research. Unexplainably low general yields as well as problem areas of deficient plant growth only confounded the results of field plot experiments. Intensive soil sampling and subsequent measurements of pH, EC_e of the saturation extract, and the four major cations disproved the previous suggestions that the crop growth problems were related to saline, sodic, or degraded soil conditions. The Ca/Mg+K+Na ratio, although significant when correlated with plant height, was sufficient explanation for only a small …

A Relativistic One Pion Exchange Model Of Proton-Neutron Electron-Positron Pair Production, William A. Peterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Proton-neutron electron-positron pair production cross sections are calculated in the framework of the pseudoscalar one-pion exchange model in a fully relativistic manner.

A computer program has been developed to evaluate invariants and Dirac traces for a given data point.

The sections for symmetric coplanar events for laboratory kinetic energies of 10 to 250 MeV were calculated for pair angles of 20° to 120°.

Frequency distributions were also calculated, at a laboratory energy of 200 MeV, using a random number generator to select data points. The frequency distributions are illustrated by curves.

It was noted that the inclusion of heavier bosons …

A Hydrologic Model Of The Provo River Basin, Utah, Craig T. Jones

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this paper is to develop a general hydrologic model for use on a digital computer and prove its validity by applying it to a management study of the Provo River Basin. Hydrologic equations have been proposed for each major hydrologic occurrence within a river basin. By linking these equations through restrictions on continuity of mass, a general hydrologic model can be obtained. Such a model becomes the basic tool for studying the management of the river basin hydrology. The paper describes the model components, parameter identification program, and the river basin management program.

This study investigated the validity of excusing students from composition courses based upon an objective examination.

Utah State University (USU) students who had taken freshman composition courses during the 1970-71 school year when these courses were required of all entering freshman students were divided into two groups: one group was composed of those who had received an "A" or "B" for three freshman composition courses, while the other group had received a- "C" or "D" for the same courses. USU students who had been excused from taking freshman composition courses based on the CLEP General Examination in English Composition (CLEP) …

An Investigation Of Cluster Analysis, John C. Klingel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three cluster analysis programs were used to group the same 64 individuals, generated so as to represent eight populations of eight individuals each. Each individual had quantitative values for seven attributes. All eight populations shared a common attribute variance-covariance matrix.

The first program, from F. J. Rohlf's MINT package, implemented single linkage. Correlation was used as the basis for similarity. The results were not satisfactory, and the further use of correlation is in question.

The second program, MDISP, bases similarity on Euclidean distance. It was found to give excellent results, in that it clustered individuals into the exact populations from …

The Seasonal Pattern Of Cavitation In Five Species Of Trees, Herond R. Hoyt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Five species of trees were studied: Acer glabrum (Hook.) Dippel, maple; Betula fontinalis Sarg., birch; Fraxinus pennsylvanica Marsh., ash; Populus tremuloides Michx., aspen; Pseudotsuga menziesii Britton, Douglas Fir. The trees were taken from naturally growing stands, between 20 and 40 years old, and about 7 m tall. The trees were cut down at eight study dates extending over 18 months. A 1.5 m section of stem and a branch from the upper and lower part of the tree were taken to the laboratory. Small pieces were then cut from these large pieces and were subsequently sliced into sections 200 microns …

Operations Research Model For Competitive Bidding, Harold Kerzner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this paper is to demonstrate a model for competitive bidding. The model is based upon a thorough knowledge of the competitors. The model is designed to optimize a solution, given the desired profit and the minimum probability of success. Various cases are considered showing how the quantitative and qualitative nature of the competitors' bidding history may influence the final optimized solution.

In order to optimize a solution, a reduction in total manhours is usually needed. The reduction in manhours increases the risk of a cost overrun upon job completion. The magnitude of the risk, as well as …

Infinite Product Spaces Under The Tychonoff And Goofynoff Topologies, James A. Capps

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The only topology considered for the infinite product of topological spaces in most current topology texts and research papers is the Tychonoff topology. Yet there is another topology which seems to be a much more topologically natural generalization of the usual "box" topology of finite products. We call this natural generalization the Goofynoff topology and exploit its properties. The use of the word "Goofynoff" (pronounced Goof'-n-off) is not universal and does not refer to any person of that name. In the few references to this topology that can be found, it is usually called simply the Box Topology. None of …

An Approach To Range Inventory For The Annual Range Type Of The Arid And Semi-Arid Regions Of The Sudan, Farid D. Iskander

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Range inventory, by definition, is the evaluation of the range resources to determine a proper and safe level of stocking and to provide a record of vegetation and vegetation changes (Stoddart and Smith, 1955). Range survey is defined by the Range Conservation Glossary, Soil Conservation Service (1944) as "a systematic and comprehensive inventory and analysis of the range resources and related management problems of a range area for the purpose of developing plans of management therefrom." Accordingly, range inventory is the quest for basic information about rangelands and the development of guides and procedures for their management, improvement and efficient …

A Linear Programming Decision Model For Elk And Deer Management On The Logan Peak Winter Range Area, Ronald P. Grove

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

One consequence of our surging human population is the corresponding increased level of resource consumption. This occurrence renders it imperative that resource managers intensify their management of the world's natural resources. Failure to improve management techniques involving the use of these resources will result in premature depletion of non-renewable commodities and severe checks on the vigor of renewable resources.

Management is faced with the difficult task of searching for astute means of allocating natural resources. Because of the tremendous size and complexity of the natural world, the problem can be extremely complicated.

Mathematical techniques have proved useful in providing natural …

The Supreme Organ Of The Mind's Self-Ordering Growth, T. Y. Booth

Faculty Honor Lectures

As is true of other organs, when language is functioning well, we pay little or no attention to it or its complexities. Part of the difficulty, in fact, of doing justice to the problems of expression and interpretation that Richards asks us to deal with is that routine language experience occurs so effortlessly, so unconcernedly, so second-natured naturally, that when we do run into difficulties we do not always recognize them as difficulties of our developing language. Or, what can be even worse, we think of the language difficulties as if they were separable, as if the thought would be …
