Studies To Further Evaluate Reoviruses As An Indicator Of Enteric Virus Pollution, Dennis Jack Adams

Biology

A protamine sulfate precipitation procedure capable of concentrating IV/PIV reovirus and rotavirus particles from large volumes of diverse waters was developed. This procedure can be used effectively with rapid immunofluorescent cell assay techniques. Protamine precipitation of both reovirus and rotavirus particles recovered 88 to 100 percent of the viruses added to water, 79 to 100 percent from secondary sewage effluent without suspended solids, 79 to 95 percent from secondary effluent with suspended solids and 82 to 100 percent from raw sewage. Twenty-two precipitations of naturally occuring reovirus particles recovered an average of 5.0 x 104/l from raw sewage. This study …

The Effect Of Trypsin On Polypeptide Composition And Infectivity Of Bovine, Simian, And Porcine Rotaviruses, John C. Roth

Biology

Bovine, simian, porcine, and human rotaviruses exhibited 8.0, 10.3, 35.4 and 3.2 fold infectivity enhancement in the presence of trypsin although optimal conditions of treatment varied between strains. Infectious titers of bovine and simian rotavirus preparations treated with 10 μg/ml trypsin decreased substantially over a one hour incubation period at 37° C. Serial passage of rotaviruses in cells without trypsin enhancement resulted in significant losses of infectivity with each passage until no infectious virus could be detected. A specific, trypsin-mediated cleavage of rotavirus structural polypeptide P3, which was consistent between rotavirus strains, resulted in the formation of two major cleavage …

The Inhibition Of Reoviruses, Rotaviruses And Orbiviruses By Selected Antiviral Substances, Donald Frederick Smee

Biology

Known RNA virus inhibitors were evaluated in vitro and in vivo to determine if any had specific inhibitory effects on reo-, rota- and orbivirus infections. Test compounds included 1-ß-D-ribofuranosyl-1,2,4-triazole-3-carboxamide (ribavirin), 3-deazaguanine (3-DG), 3-deazauridine (3-DU), and 9-(S)-(2,3-dihydroxypropyl) adenine ([S]-DHPA). Certain selected studies were also run with the following ribavirin derivatives: ribavirin 2' ,3' ,5'-triacetate, ribavirin 5'-monophosphate and ribavirin 5'-triphosphate. Viruses included types 1, 2, and 3 reovirus; bovine, porcine and simian rotaviruses; and bluetongue and Colorado tick fever orbiviruses. Results of the in vitro antiviral studies indicated ribavirin to be the most potent anti-reovirus agent, and 3-DG the strongest rota- and …

Stream Insect Production As A Function Of Alkalinity And Detritus Processing, Thomas G. Osborn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The study was conducted to determine if aquatic insect production was significantly different between high and low alkalinity mountain streams and if any differences were associated with food availability factors. The major objectives included determining: (1) if annual production differences occur between high and low alkalinity streams; (2) if processing rates of terrestrial detritus differs between high and low alkalinity streams; (3) if detrital processing rates are related to stream insect productivities; (4) if primary productivity varies between high and low alkalinity streams; (5) if toxic effects or micronutrient limitations exist in high or low alkalinity streams that could limit …

Biofeedback: A Possible Substitute For Smoking, Earl Eugene Griffith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Numerous agencies have accumulated evidence since 1964 which implicates habitual cigarette smoking as a causal or facilitating factor in the development of many circulatory and respiratory diseases. This study sought to identify those psychological variables which possibly contribute to the maintenance of cigarette smoking and therefore, had two main purposes. First, this study investigated the individual and simultaneous physiological changes, i.e., Electroencephalography, Electromyography, Heart Rate, Blood Pressure and Skin Temperature that occurred during and immediately after the smoking of one cigarette. Second, the study investigated the hypothesis that smoking frequency would decrease when individuals were trained via biofeedback procedures to …

Objective Indices Of Disaster-Related Stress: The Mount St. Helens' Ashfall, Paul R. Adams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

On May 18, 1980, the town of Othello, Washington was covered with volcanic ash from the Mount St. Helens eruption. Disaster research suggested that a natural disaster acted on impacted populations as a major stressor and could result in such stress-related symptoms/problems as anxiety, depression, alcohol abuse, family problems, etc. It was hypothesized that there would be an increase in the incidence of such symptoms/problems following the ashfall. Most previous research has relied on subjective accounts of victims, but data for this study came from selected objective indices such as mental health caseloads, welfare assistance grants, hospital admissions, police records, …

Twenty-four pairs of children in the first through fourth grades were compared. The achievement scores of the second and fourth grade student pairs were compared for the current academic year and for the previous academic year. A two-way analysis of Variance was used to compare the achievement scores from the Iowa Test of Basic Skills of the two groups. The results indicated statistical significance on some subtests of the first and fourth grade …

The Effect Of Support Groups In Reducing Stresses During The Transition To Parenthood, Lynne Wilson Myers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Forty-two couples expecting their first child volunteered to participate in a study of the transition to parenthood. Personal well-being, self-esteem, marital satisfaction, and parenting competence of the couples were assessed during pregnancy, and then again when babies were six weeks and fifteen weeks old. Parents were asked to report how much support they had received from their doctors, churches, family, and friends, and other sources, after their baby was born. Personal well-being and parenting competence increased for women after they became mothers. Personal well-being decreased and parenting competence increased for new fathers. Marital satisfaction decreased significantly after couples had their …

Temperamental Characteristics Of Sociometrically Identified Preschool Children, Melinda M. Toney

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This research investigates the relationship between temperament and sociometric status utilizing a sociometric picture technique and the Parent Temperament Questionnaire for Children 3-7 Years of Age, a measurement instrument from the New York Longitudinal Study. The study population consists of sixty-one preschool age children. In the final stage a discriminant function analysis was employed to determine if there was a relationship between the measures of temperament and sociometric status. Although no significant functions emerged, two functions approached significance. The results indicate that popular and amiable children score higher on adaptability and approachability than isolated and rejected children. Also, distractibility appeared …

Psychosocial Maturity In 4-H And Non 4-H Youth, Robert Leon Young

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was undertaken to add to the knowledge of the psychosocial effects of the 4-H program upon its members. The objectives were to determine if 4-H involvement is associated with the psychological and social maturation of adolescent members, and to investigate how several variables such as age, urban/rural residence, and S. E. S. may help explain this relationship or lack of relationship.

To accomplish these objectives 165 youths (103 4-H, 62 non 4-H) and one parent of each youth, responded to mail-out questionnaires, answering questions of biographical content, and items from the Psychosocial Maturity inventory. Responses were compiled and …

Diagnostic Considerations In The Identification Of The Hyperactive Child, Barbara Jagoda Draheim

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

The hyperactive disorder of childhood and the enumeration of its features were described in two papers published in the mid-1950's, by Laufer and his colleagues (Laufer, 1957; Laufer, Denhoff & Solomons, 1956). It was a list that has since become familiar; short attention span, impulsivity, irritability, low frustration tolerance, poor academic achievement, and visual-motor difficulties. Like many who have since searched for definers of the syndrome, Laufer and his colleagues remarked upon the perplexing variability displayed by these children, and they noted that no single symptom could be considered diagnostic. They described the development of "secondary psychological difficulties" due to …

Approaches To Adult Probationary Supervision: A Positive Perspective, Douglas Wilson

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

The field of probationary supervision today is marked by division and confusion. The probation officer who attempts to define the most effective approach to supervision is confronted with conflicting advice or, perhaps even worse, no advice at all. As Allen, Carlson, and Parks (1979) point out:

• In summary, if we ask which caseload management strategies have been shown to be the more effective or efficient, we must answer that too little research has been done in this area to come to any definitive conclusion. (p. 67)

In spite of the lack of research to provide a "definitive conclusion," the literature …

Single...Chance Or Choice, Karen Robinson

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

"It is said to be the largest unrecognized minority group in America, but it has no lobbying efforts, central organization or focus. The group is singles - divorced, widowed or never married - and there is an estimated l 190,000 of them in Kansas City Area." One out of every three adults in the United States is single. That is 43 million. Yet in spite of their great numbers, single people find that social pressures still call for "settling down" and raising a family.

The Effects Of Psychodiagnostic Information And Therapist Accountability On Psychotherapeutic Outcome, Alan Leonard Zohner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to determine the effects of psychodiagnostic information provided by the Symptom Checklist-90-Revised (SCL-90-R) and the Hopkins Psychiatric Rating Scale (HPRS), and therapist accountability on the psychotherapeutic outcome measures of goal attainment scaling (GAS), number of client-therapist sessions, length of treatment, therapist ratings of client improvement, and type and frequency of client termination. The subjects of this study were 72 persons who sought services at Bear River Community Mental Health Center, Logan, Utah, and who, subsequently, were assigned to one of eight participating therapists at this center. These clients were divided into three treatment groups …

Examination Of The Effect Of Physical Exercise On Metabolic Control In Type I Insulin-Dependent Youth With Diabetes Mellitus, Gayle Ann Brazzi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There is evidence for the importance of physical exercise balanced with diet and insulin therapy in the treatment and control of Type I insulin-dependent diabetes mellitus. Recent attention in the literature has focused on the once neglected component of treatment--exercise. A well-controlled exercise state is generally believed to be beneficial for the individual with diabetes. Limited studies are available on the effect of exercise on long-term metabolic control. Before exercise levels can be professionally prescribed for a given population of youth with diabetes, current exercise patterns should be evaluated as to the effect on long-term metabolic control.

It is the …

Bioavailability Of Calcium, Fluoride And Iron In Mechanically-Deboned Beef Fed To Growing Rats, Kathryn Mclaughlin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Weanling rats were fed diets containing raw lyophylized hand-deboned shank beef (HDS) supplemented with CaCO₃, retorted lyophylized mechanically deboned shank beef (MDS), or raw lyophylized MDS. Ca in the latter two diets originated from bone during the mechanical deboning process. Ca absorption, Ca retention, bone weight, and bone breaking strength were similar for comparative dietary levels of Ca regardless of the source. Bone ash and Ca content was significantly higher (P < .05) in the MDS 393 (3.93 g Ca/kg diet) diet and in the retorted MDS 460 diet compared with the HDS 488 diet. Relative biological values for the MDS diets calculated relative to the HDS diets ranged from 102 to 132 when the linear regression of Ca consumed, Ca retained, or dietary Ca level vs bone ash or bone Ca content was obtained. The retorted MDS 460 diet contained the highest Fe level and exhibited a lower percent absorption, terminal hemoglobin level, and liver Fe storage. Humerus F content increased as dietary F (also present from bone) level increased. Dietary F level did not determine humerus breaking strength.

The Effects Of Myoglobin, Nitrosylmyoglobin, And Free Iron On The Growth Of Clostridium Botulinum In Cured Meat, Susan K. Fortier Collinge

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Although nitrite is a known inhibitor of Clostridium botulinum in cured meats, the mechanism of inhibition is not understood. The observation has been made that iron is required for growth of C. botulinum and that the role of nitrite may be to alter the pathway of iron uptake by these organisms. Since the color change in cured meats is due to the binding of nitrite to the heme group of meat pigments, it was hypothesized that nitrite may also be tying up an essential iron source, heme. This experiment was an investigation of the possibility that myoglobin added to a …

Vitamin A And Vitamin E Status Of Persons On Hemodialysis, Kathleen S. Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The study was designed to assess the vitamin A and vitamin E status of persons receiving maintenance hemodialysis. Blood samples from thirty persons receiving hemodialysis, as well as age and sex-matched controls, were analyzed for vitamin A, vitamin E, and carotene using a spectrofluorometric assay for vitamins A and E, and a spectrophotometric assay for carotene. Dietary intakes of vitamins A and E were estimated via verbal questioning. Samples of dialysate were also studied. Results of the investigation showed significantly elevated vitamin A, normal vitamin E, and decreased carotene levels in persons with renal failure receiving maintenance hemodialysis, when compared …

The Effect Of Parent Involvement In A Nutrition Education Program For Primary Grade Pupils, Barbara A. Kirks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three schools were matched for socioeconomic data, location, and quality. Students in kindergarten through grade three in two schools received nutrition education; the third school was the control. Of the two treatment schools, one was randomly assigned to receive parent as well as student education in nutrition. Three-hundred and seventy cognitive scores, 168 affective scores, and 100 plate-waste analyses were collected in both pretest and posttest phases. At the end of the four-month treatment period, 24-hour food frequency recalls were collected for 151 children.

Students at the school where both parents and their children were involved had higher dietary quality …

Economic Analysis Of Long-Term Management Strategies For Two Sizes Of Utah Cattle Ranches, Roger E. Banner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah cattle ranchers realize relatively little profit from ranch ownership and management. This study represents an attempt to identify ranch management strategies that produce more profit over time than do conventional strategies.

To identify optimum management strategies for the long term, analyses of ranches under both normal and adverse ranch operation conditions using the COPLAN linear programming model were made for strategy comparison. To depict these ranch business environmental conditions, production levels were estimated from available biological data and price levels were estimated by indexing 1977 ranch product prices (the most current budget data available for Utah). The variability of …

Lifestyle As A Determinant Of Participation Among Dispersed Forest Recreationists, John R. Butler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study assesses the usefulness of lifestyle as a determinant of outdoor recreation behavior. Two objectives of the study are: (1) develop an operationalized concept of lifestyle that is based on theory, and (2) apply this concept in a model which uses lifestyle as a variable influencing recreation behavior.

The first objective was approached through an integrative review of the literature. Lifestyle was set in context of cultural theory. The basic postulate of the proposed theory of lifestyle is: If an individual's lifestyle is similar to that of another, certain social psychological processes are similar. Therefore, their patterns of needs, …

Allegory And Nietzschean Values In Kafka, Camus, And Kazantzakis, Paul Kenneth Naylor

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this these is to explore Nietzschean values as they appear in three modern allegories: Franz Kafka's The Castle, Albert Camus' The Plague, and Nikos Kazantzakis' Zorba the Greek. The intent is to illustrate Friedrich Nietzsche's three stages of the overman as they apply to Kafka, Camus, and Kazantzakis.

Locus Of Control: Effects On The Reported Gains Made In Assertion Training, Eugene Earl Campbell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Forty-nine Cache Valley residents, between the ages of 18 and 45, who volunteered to participate in an assertion training class were assigned to one of seven groups. Subjects were administered pre- and posttests and a two month follow-up evaluation. Measures included Rotter's Internal-External Locus of Control Scale, the Rathus Assertive Scale, and the Berger Self-Acceptance Scale. The results obtained indicate that self-acceptance and assertiveness changed as a result of assertion training and that these changes were maintained at follow-up. No difference between internals and externals was observed as a result of semi-structured assertion training.

Ego Strengthening Hypnotic Suggestions Versus Specific Hypnotic Suggestions In The Treatment Of Obesity, Richard A. Hutchison

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A comparison was made of two types of hypnotic suggestions. Twenty seven subjects in two groups participated in eight weekly one-hour group hypnotic sessions. All subjects were given the Minnesota Multiphasic Personality Inventory, the Tennessee Self-Concept Scale, and were weighed pre, post and at four month follow-up. Both types of hypnotic suggestions were equally effective in helping individuals lose weight. The average weight loss was 10 pounds at follow up. Both groups showed improvement on the personality tests. Those who received the ego-strengthening hypnotic suggestions showed more improvement and more long lasting improvement than did those who received the specific …

Cause And Perceived Seriousness Of Deviant Behavior And Attribution Of Responsibility, Mary Kathryn Morris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to investigate the relationship between differing stated causes of deviant behavior which is commonly labelled mental illness, and the perceived seriousness of these behaviors in determining judgments of the degree of responsibility attributed to described deviant individuals. This was accomplished by having subjects rate four different vignettes as to degree of perceived seriousness and degree of responsibility for behavior.

The subjects were 76 undergraduate students enrolled in either introductory psychology and/or introductory anthropology. The subjects were divided into four groups. Each group of 19 subjects received the same four vignettes. Each vignette gave a …

Marital Roles And Their Relationship To Marital Happiness And Self Concept, Gary L. Devries

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Marital roles have become a subject of major concern in recent years. Many critiques consider traditional marriage roles to be responsible for hindering appropriate social-emotional development of the wife, in particular, and also the husband. Past research in assessing the relationship between marital roles and the happiness and well-being of husbands and wives is limited in quantity and generally is inconclusive or controversial. This study was designed to clarify the relationship between marriage roles and two dependent variables, marital happiness and self concept.

The sample population consisted of 124 volunteer couples selected from the teaching staffs of eight school districts …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to determine the factors which affected the decision of students not to return to Utah State University after completion of the previous quarter. The factors were determined by a mailed questionnaire which was a modification of the Withdrawing/Nonreturning Student Survey developed by American College Testing (ACT).

One hundred twenty-two former Utah State University students who had attended fall quarter, 1979 but failed to register for winter quarter were randomly chosen for the study. The students were asked to complete the questionnaire and return it to Utah State University. The return rate through the mail …

A Peer-Managed Self-Control Program For Reduction Of Alcohol Consumption In High School Students, Richard Allan Carpenter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three treatments designed to reduce the consumption of alcohol by native American high school students were assessed and compared. Self-referred and staff-referred clients were randomly assigned to three treatment groups: (1) alcohol education and a peer-assisted self-control procedure, (2) a peer-assisted self-control procedure, and (3) a self-monitoring only procedure. All three treatments were conducted by trained peer counselors for 14 weeks. The alcohol education and peer-assisted self-control and the peer-assisted self-control demonstrated reductions in peak blood alcohol concentration, frequency of drinking incidents, and alcohol consumption. The self-monitoring only group demonstrated changes only in frequency of drinking incidents. No significant differences …
