Client Preferences For Counselor Characteristics: Attitudes Towards Handicapped, Benjamin D. Ewing

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The objective of this research was to constructively replicate the research of Brabham and Thoreson (1973) and Mitchell and Frederickson (1975) that led to the conclusion that handicapped counselors are preferred.

Subjects were 337 male and female volunteers enrolled in psychology 101 which was taught during the Fall Quarter, 1984, at Utah State University. All subjects were asked to indicate their preference when considering 20 hypothetical problem situations for one counselor from among six photographs of handicapped and non-handicapped counselors. The 20 situations consisted of three types (personal, vocational, and educational). Each subject's score was the total number of times …

The Effects Of Fluoride On Chloroplast And Tonoplast Biochemical Functions, John L. Giannini

Biology

The exposure of isolated chloroplast and tonoplast vesicles to solutions containing soluble fluoride compounds results in reduced rates of photochemical activity. These reductions can be related to fluoride's effects on the chemistry of these structures. In the chloroplast, photophosphorylation was inhibited. This inhibition was due to binding of fluoride to the chloroplast ATPase (CF₁). Other major functions (Calvin cycle, PSI, PSII, NADP+ reductase) were not affected. The tonoplast was inhibited in two ways. The tonoplast ATPase shows decreases in activity at high fluoride concentrations above 30 mM. At concentrations lower than 30 mM the ATPase is not affected …

Wireworms (Coleoptera:Elateridae) Affecting Wheat And Barley In Cache County, Utah, Alexander Gordon Liki

Biology

Elaterid, or wireworm, larvae occur commonly in farms around Logan, Cache County, Utah. Farmers have reported damage to crops such as wheat, barley, corn and vegetables. Field observations have verified the presence of wireworms on many crops. Wirewarms affecting wheat and barley were studied during two seasons. The major wireworm activity occurred during May and June. Wireworms occurring in wheat and barley fields were sampled and evaluated during 1981 and 1982. Nearly all species were Aeolus mellillus or Limonius infuscatus. Larger larvae of both these species inflicted damage to crops, mostly during May. Aeolus mellillus larvae predominated in wheat …

The Water Economy Of Nestling Swainson's Hawks (Buteo Swainsoni), John S. Kirkley

Biology

The six major components of the water economy of nestling Swainson's Hawks (Buteo swainsoni) were quantified and incorporated into water budget scenarios demonstrating the effects of heat stress and dietary composition on water balance. Four consecutive 1-week food trials were conducted on each of 16 nestlings to measure rates of food consumption, growth, energy utilization, excrement production and pellet production. Rates of evaporative water loss and CO2 production were measured gravimetrically on 28 nestlings under 4 thermal conditions (25°C, 35°C, 42°C, and 30°C plus sunlight) using an open flow indirect calorimetry system. Water utilization components ( i.e., water …

The Relationship Between Therapist Approach Postures, Avoidance Postures And Posture Sharing, And Subjects' Experience Of Rapport, Lawrence A. Carcelli

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relationship between approach, avoidance and congruent postures and the experience of rapport was investigated. Sixty undergraduate college students (30 male, 30 female) were interviewed by a therapist who displayed either approach postures, avoidance postures or who posture shared. The degree of rapport experienced by the 20 subjects in the three groups was compared. In addition, the subjects' behaviors were divided into four groups (n = 11, or 19) along two orthogonal dimensions (high and low congruency and immediacy) and the degree of rapport experienced by the four groups compared. No statistically significant results were found in either analysis. An …

Brownian Motion Applied To Partial Differential Equations, Steven M. Mckay

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This work is a study of the relationship between Brownian motion and elementary, linear partial differential equations. In the text, I have shown that Brownian motion is a Markov process, and that Brownian motion itself, and certain Stochastic processes involving Brownian motion are also martingales. In particular, Dynkin's formula for Brownian motion was shown. Using Dynkin's formula and Brownian motion, I then constructed solutions for the classical Dirichlet problem and the heat equation, given by Δu=0 and u_t= 1/2Δu+g, respectively. I have shown that the bounded solution is unique if Brownian motion will always exit the domain of …

Habit Reversal Treatment Of Bulimia Nervosa, Ken Small

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Although several writers have emphasized the habit-like characteristics of bulimia nervosa, no study has investigated the extent to which bulimia responds to treatment specifically for habit disorders. Habit reversal is a general treatment plan which teaches individuals to regain lost awareness of all aspects of a habit. The habit is then interrupted at the earliest movement in the chain by a physically competing response. Habit reversal (Azrin & Nunn, 1973) has been effective in treating other habits (e.g., stuttering, tics, bruxism). In the present study, habit reversal was adapted for the treatment of bulimia.

In response to newspaper advertisements, ten …

The Welfare Impacts Of Environmental Regulation In An Open Economy, Nicole Glineur

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The major theoretical and practical economic issues on pollution have apparently been sorted out. However, the bulk of the literature in environmental economics shares a shortcoming: the disregard of the welfare implications and consequences of pollution control.

Traditionally, pollution is viewed as a joint product. In this study, the issue of trade and environmental regulations is cast as a problem of input regulation, and the subsequent welfare implications of input regulation are then derived. The purpose of the present research is to emphasize the welfare consequences of pollution control in the context of international or interregional trade. The Batra and …

Chemical Weathering Of Pyrite In Soils, Aaron D. Brown

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The products of pyrite oxidation, including solution phase Fe²⁺, Fe³⁺, S₂O₃^2-, S₄O₆^2-, SO₃^2- and SO₄^2- and solid phase Fe(OH)₃, were measured under controlled conditions in order to investigate the behavior of pyrite in calcareous and alkaline soils.

The distribution of sulfur oxidation products is pH dependent and can be interpreted in terms of metastable equilibrium among thiosulfate, disulfane disulfonate and sulfite. Thiosulfate and sulfite predominate in the pH range greater than about pH 7 or 8. Sulfane disulfonates are more …

Factors Affecting Feeding Injury To Grasses By Adult Billbugs (Coleoptera: Curculionidae), Dale C. Nielson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Factors associated with feeding injury to grass plants by two species of adult billbugs, Sphenophorus gentilis and S. parvulus, were evaluated. Early season tests utilized adult bluegrass billbugs while later studies involved wildrye billbugs. Types of feeding injury were determined and preferred feeding locations on host plants were identified for each billbug species. Greenhouse and field studies compared different species of grasses, individual plants within a species, and plants from different locations, for billbug susceptibility. The effect of grass plant age and stem size were also tested using bluegrass billbugs.

Using analysis of variance and multiple comparison tests, significant …

Self Esteem And Adolescent Sexual Attitudes And Behavior, Roger B. Christensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was designed to determine; (1) if adolescent self esteem is related to premarital sexual attitudes and intercourse behavior; (2) if religious affiliation and church attendance affect the relationship between adolescent self esteem and premarital sexual attitudes and behavior. Approximately 2400 adolescents residing in California, New Mexico, and Utah comprised the sample.

Adolescents who attended church services more often reported less sexually permissive attitudes and behavior than those who attended church less often. Similarly, Mormons' premarital sexual attitudes and behavior was more conservative than was the case for non-Mormon adolescents. Findings indicated that the nature of the relationship between …

A Comparison Of Traditional Preschool And Computer Play From A Social/Cognitive Perspective, Jeanne M. Hoover

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Twenty females and twenty-three males from the Utah State University Children's House participated in this study which compared traditional preschool play with computer play. The Parten/Smilansky nested social/cognitive play hierarchy was used. Sociometric and cognitive assessments were incorporated in order to more clearly define behaviors. Five types of play were observed: computer, art, locks, manipulative toys, and the dramatic area.

No gender differences were found in terms of the amount of time or type of play at the computer. However, sociometric status did influence computer play. Children who engaged in more positive social interactions used the computer constructively, while those …

Beta-Endorphin And Running Addiction: Use In The Treatment Of Schizophrenia, Mania, Depression, And Anxiety, James Glenn Rogers

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

Neither Glasser's (1976) survey data nor popular magazine articles (which seldom cite references) have provided conclusive evidence regarding the existence of running addiction or established causality between this addiction and Beta-endorphin. An integration and summarization of research on the effects of opiates, Beta-endorphin and running will answer the following question, or indicate where evidence is insufficient and explore avenues that require further research.

• Question 1: Is distance running addictive and if so, what is the role of Beta-endorphin in this addiction?

Secondly, prior reviews of research of the effects of opiates and Beta-endorphin on psychopathological illnesses will be combined with …

Factors Which Influence The Development Of Bloom (Redness) In Dark Colored Muscle, William Russell Egbert

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effects of acidification, low temperature, high oxygen concentration, and rotenone on the color of dark colored beef muscle were determined by use of the Hunter color difference meter. Pre-rigor and dark cutting muscle homogenates bloomed (turned bright red) in the presence of low pH or rotenone. Dark cutting homogenates also bloomed at low temperature. Pre-rigor and dark cutting muscle slices turned bright red at low temperature in an oxygen atmosphere. In dark cutting beef muscle however, low temperature was sufficient to cause the development of bloom. Factors which inhibit mitochondrial respiration influence the development of bloom in dark colored …

Effect Of Iron On Residual Nitrite Level In Ground Pork And Model Systems, Changmin Kim

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effects of iron, temperature, and presence of botulinal spores or sodium ascorbate on depletion of nitrite level were determined in meat and model systems. Higher temperature and presence of botulinal spores definitely increased nitrite depletion in a meat system. Added hemoglobin also significantly increased nitrite depletion, while ferrous iron and ferric iron did not significantly decrease nitrite level in a meat system. High temperature and presence of sodium ascorbate increased nitrite depletion in a model system. Only ferrous iron significantly decreased nitrite level in the absence of ascorbate, while ferric iron, heme iron, and ferritin iron did not decrease …
