The Effect Of Right-To-Work Laws On Unionization In The United States, H. Craig Petersen, Keith Lumsden

Economics and Finance Faculty Publications

State right-to-work laws, the subject of considerable controversy in the industrial relations field, typically state that no person will be required to become a union member or, conversely, be required to abstain from union membership as a condition of obtaining or retaining employment. Little hard evidence exists on the effect of right-to-work laws. Meyers (1955) concludes that in Texas the law does not appear to have had a noticeable impact on union strength. Kuhlman (1955) finds that the Virginia law has caused little change in hiring practices, and he cites lack of enforcement as a major cause. Novit (1969), in …

Auroral Energy Input From Energetic Electrons And Joule Heating At Chatanika, Vincent B. Wickwar, M J. Baron, R D. Sears

All Physics Faculty Publications

With the incoherent scatter radar at Chatanika, Alaska, a wide variety of measurements can be made related to the ionosphere, magnetosphere, and neutral atmosphere. A significant parameter is the amount of energy transferred from the magnetosphere into the ionosphere and neutral atmosphere during periods of auroral activity. In this report we examine a procedure whereby the incident energy flux of auroral electrons is ascertained from radar measurements. As part of the process we compare radar-determined fluxes with those ascertained from simultaneous photometric observations at 4278 Å. The fluxes obtained by both techniques had similar magnitudes and time variations. If we …

Food And Distribution Of Underyearling Brook And Rainbow Trout In Castle Lake, California, Wayne A. Wurtsbaugh, R. Brocksen, C. Goldman

Watershed Sciences Faculty Publications

A difference was found in the summer distribution of underyearling brook trout, Salvelinus fontinalis (Mitchill), and planted rainbow trout, Salmo gairdneri Richardson, in Castle Lake, California. Brook trout underyearlings oriented to the bottom and were found primarily in shallow water on the eastern shore of the lake near springs. The rainbow trout underyearlings were more pelagic and were found in the littoral areas along the entire shoreline. Gravimetrically, the food eaten during the summer by brook trout underyearlings was 13% terrestrial, 11% limnetic, and 76% benthic. Rainbow trout ate 15% terrestrial, 15% limnetic, and 70% benthic food. In summer, rainbow …

A Field Technique Measuring Virus Decay And Potential Aerosol Hazard From Wastewater Sprinkler Irrigation, Michael F. Torpy, Robert A. Gearheart, J. Clifton Spendlove, Rex S. Spendlove

Reports

The increased use of domestic wastewater for irrigation purposes has stimulated a growing practice of sprinkler irrigating from oxidation ponds and other domestic wastewaters. Aerosols generated from these sprinkler irrigation systems may contain potentially hazardous pathogens. Subsequently, the aerosols can contain infective viruses which can be carried through the air to surrounding populations. Thus, a public health hazard can be created by sprinkler irrigating domestic wastewater. This study is an investigation of a means by which the virus decay rate of viruses in aerosols and the potentials hazard of sprinkler irrigation aerosol clouds may be examined. A means of injection …

Regional Development: An Econometric Study Of The Role Of Water Development In Effectuating Population And Income Changes, Herbert H. Fullerton, Chris W. Lewis, Jay C. Andersen, John E. Keith, Reed Willis

Reports

Twelve measures of regional economic growth, including populations and three measures of income were compared for areas with and without water investment in 246 counties and 42 water resources subareas in the states of Utah, Colorado, New Mexico, Montana, Wyoming, Idaho, and Nevada. Simple mean omparisons for these measures compiled for the decades of 1940-1950, 1950-1960, and 1960-1970 failed to support the hypothesis that economic growth of those counties and subareas receiving water investment was significantly highter than in those areas which did not, with the possible exception of the 1940-1950 decade. This result is obciously tempered by the fact …

The Computation Of Eigenvalues And Eigenvectors Of An Nxn Real General Matrix, Yeh-Hao Ma

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

The eigenvalues of the matrix eigenproblem Ax = λx are computed by the QR double-step method and the eigenvectors by inverse power method.

The matrix A is preliminarily scaled by the equilibration and normalization procedure. The scaled matrix is then reduced to an upper-Hessenberg form by Householder's method. The QR double-step iteration is performed on the upper-Hessenberg matrix. After all the eigenvalues are found, the inverse power method is performed on the upper-Hessenberg matrix to obtain the corresponding eigenvectors.

The program consists of five subroutines which is able to find real and/or complex eigen value/vector of an nxn real matrix.

An Investigation Of Oral Stereognosis And Articulation In Sighted And Blind Children, Mariette Johnson Milbrandt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this investigation was to determine if a significant difference exists between oral stereognosis skills of blind and sighted children. The possibility of a relationship between oral stereognosis and articulation was also explored in both the sighted and blind populations. A group of twenty-four blind and a group of twenty-four sighted subjects between the ages of seven and twenty were divided into subgroups of those having normal speech and those with defective articulation. There were twelve subjects in each subgroup. A 20-item test of oral stereognosis (NIDR forms) was administered to each subject and error scores taken.

An Analysis Of Participation And Leadership In A College Seminar, Hugh J. Phillips

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The task of this research was to describe the rates and patterns of verbal behavior emitted in a college seminar, under two leadership conditions, teacher leadership and student leadership. The subjects were 12 college students and the course's associate professor. The data were gathered by using R. F. Bale's interaction process analysis. Results indicate that rates of verbal behavior and numbers and rates of paired student-to-student interaction were higher under student leadership than under teacher leadership. In addition, there was a more equitable distribution of responses under student leadership than under teacher leadership.

Social Organization Of The Cassin's Finch In Northern Utah, Fred Burton Samson

Biology

Cassin's Finch populations were studied in northern Utah during three breeding seasons and three winters to determine patterns of breeding, factors limiting breeding population size, social dominance and individual survival in winter flocks, and interrelationships of social systems between the seasons. Population levels on the breeding area, Beaver Mountain, Cache County, exhibited marked fluctuations from year to year; and males significantly outnumbered females in these populations. Cassin's Finches nested in colonies that varied in size from 9 to 20 nests. Adult males in reddish plumage predominated in breeding; but, if lost from the population or experimentally removed by shooting, they …

Characteristics And Genesis Of The Parleys And Mendon Soils Series In Northern Utah, Khalid I. Al-Amin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The study was designed to test the genetic theory of soil development of two soils derived from different geological material, but developed under conditions of similar climate, topography, biological activity, and age. An attempt was made to relate the soils characteristics to their present classification. Parleys and Mendon series which developed from Bonneville and Salt Lake Formation, respectively, were selected for that purpose. Along the east side of Cache valley, two pedons representing each of the studied series were selected to have similar soil formers except for their parent material.

Evidently, these studied soils have been developed from different heterogenous …

The effect of compensatory education was studied as it influences school readiness in preschool children. The research was conducted in the Logan and Providence areas of Cache County, Utah, with 44 children who had completed the kindergarten year of school. Twenty-two of the children had participated in the compensatory educational experience of Head Start prior to their kindergarten experience. It was found that there was not a significant difference between the Head Start children and their neighbors in terms of their performance on the Boehm Test of Basic Concepts. Therefore, in terms of school preparedness, the Head Start children seem …

Vocalizations In A Population Of Green-Tailed Towhees (Chlorura Chlorura), Timothy Andrus Burr

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Studies of vocalizations in a montane population of Green-Tailed Towhees were conducted during the summer months of 1971 and 1972 in Cache County, Utah. The song and call repertoiries of 10 breeding pairs were recorded and analyzed on a sound spectograph.

Males averaged 8.7 different song and 18.2 different not types. Song variation on the population level is high (58 different songs) but the sharing of these songs among the males is low (22.4). Populational note structure is equally diverse but reveals a greater degree of sharing (75%).

Both males and females used three calls, the meow, tick, …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study of the Merriam's wild turkey was conducted March 1972 to August 1973 in southwestern Utah to determine the life history and habitat utilization. Using transects, bio-telemetry, and observational techniques, information on flocking, hen:poult and sex ratios, and approximate dates for spring dispersal, nesting, and hatching was obtained. Turkey observations in relation to habitat variables were used to determine habitat utilization.

Except during the spring mating season, male flocks remained apart from other turkeys. Hen flocks in fall and winter consisted of adult hens and juveniles of both sexes. Males dispersed from winter flocks in March, and those that …

Characterization Of Selected Bacteria From The North Arm Of The Great Salt Lake, John L. Crane Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Thirteen bacterial cultures were isolated from the North arm of Great Salt Lake during the months of January and February of 1973. Eleven isolates were gram-negative pleomorphic rods which lysed in hypotonic solution. The remaining two were gram-positive cocci. All isolates and one known strain of Halobacterium salinarium were subjected to examination of morphological, cultural, physiological, and biochemical characteristics. A numerical taxonomic analysis was applied to the compiled characters to compute a coefficient of similarity for each individual isolate as compared to all other isolates. A comparative analysis was included in the similarity computation using characters assembled from those reported …

Intraregional Efficiency Of Production Decisions And Interregional Efficiency Of Input Use In Bolivian Agriculture, Stephen C. Hammond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The main objectives of this study were to analyze the efficiency with which Bolivian farmers utilize productive resources as they combine them in crop production and to examine the possibility of interregional resource immobility in the production of agricultural products.

Bolivia was divided into seven distinct production regions called departments. A linear program maximizing model was generated for the major crops produced in each department. Land, labor, irrigation, and capital were the input coefficients used in the models. They produced a net return to management, land, and fixed costs associated with land. The linear program using these coefficients generated the …

The basal contact of the Nounan Formation is sharp, but dolomite extends irregularly downward into limestones of the Bloomington Formation as much as 6 feet.

The Nounan Formation is divided into three members based on lithologic characters: (1) a lower member composed of dark, medium-crystalline dolomite; (2) a middle member composed of white, coarse-crystalline dolomite with tongues of dark dolomite; and (3) an upper …

The Dynamics Of Root Growth And The Partitioning Of Photosynthates In Cool Desert Shrubs, Osvaldo Alberto Fernandez

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study addresses the nature of physiological and phenological evolutionary strategies of root growth dynamics and energy allocation followed by Atriplex confertifolia, Ceratoides lanata, and Artemisia tridentata growing in their natural cool desert environment.

Root observation chambers with inclined Plexiglass windows were installed in monospecific desert communities of Atriplex confertifolia, Ceratoides lanata and Artemisia tridentata. Soil temperature and water potential measurements taken immediately adjacent to the observation windows indicated a minimal disturbance was caused by the presence of these chambers. For the three species initiation of root growth was observed before initiation of shoot activity, furthermore, active root growth extended …
