The Invention Of Oz, Janet Faye Daley Lysengen

Theses and Dissertations

Since L. Frank Baum published his first Oz book in 1900, Oz has become an integral part of American society; yet, only recently have his books begun to receive critical attention. Critics seem most interested in dealing with them in terms of sociology, popular culture, and psychology, but a few have recognized Baum's contributions to the birth of science fiction, to the depiction of a female hero in Dorothy, and to Baum's imaginative and perceptive examination of what separates humans from machines. This thesis will analyze the literary dimension of the Oz series. The goal will be to perceive the …

The Effects Of Keyguard Use And Pelvic Position On Speed And Accuracy Of Typing For A Physically Handicapped Child: A Case Study, Diane J. Berg

Theses and Dissertations

A single case study was designed to explore the effects that two pelvic positions and the use of a keyguard have on a physically handicapped child's speed and accuracy in typing. The subject, an 8-year-old male with cerebral palsy, was positioned in four combinations of keyguard versus non-keyguard use and neutral versus posterior pelvic positions during eight typing sessions over a time period of one month. A two way analysis of variance by regression using a linear model was performed on speed and accuracy. The results indicated that the use of the keyguard increased accuracy (p < .01) and decreased speed (p < .01). Pelvic positioning did not appear to have a major effect on either speed or accuracy. Informal observations indicated that typing alone did not have a significant effect on spelling skills. Recommendations for further studies are addressed.

Free-Form Deformations In A Constructive Solid Geometry Modeling System, Scott R. Parry

Theses and Dissertations

No one will question that computers are revolutionizing the design industry. It is pointed out in [Bezier84] that before CAD/CAM, a surface was defined by tracing cross sections on a drawing and then carving these sections in wood, plastic or metal. The final model was determined by someone interpolating between the sections. This labor intensive art is being replaced by techniques of computer aided geometric design.

Serotonergic Mediation In The Activity Of Anticonvulsant Compounds (Neurotransmitter, Diazepam, Phenytoin)., Larry Marvin Leadbetter

Theses and Dissertations

The role of the central nervous system neurotransmitter serotonin was evaluated on the anticonvulsant activity of various compounds. Serotonin (5-hydroxytryptamine) is known to have an inhibitory role in central nervous system activity. A facilitation of the anticonvulsant activity of benzodiazepines has previously been attributed to increased serotonin activity.Male white mice of the ICR strain were administered varying doses of phenytoin, 5-ethyl, 5-methylhydantoin (EMH) and JAW-669, then challenged with maximal electroshock. The occurrence of seizures was used to evaluate the degree of protection provided by a given dose of anticonvulsant.The role of serotonin on the anticonvulsant activity of these compounds was …

One questionnaire was sent to all 278 North Dakota schools having secondary business education programs, and the other to 1,000 randomly selected North Dakota businesses. Education respondents were asked to identify which applications they taught and the amount of time (emphasis) placed on teaching each. Business respondents were …

Effects Of Zinc Deficiency On Sertoli Cell Number And Ultrastructure: An In Vivo And In Vitro Study., Gro Thorne-Tjomsland

Theses and Dissertations

Hypogonadism in the male is a well known clinical symptom of zinc deficiency. The testicular lesions have been primarily attributed to the effects of decreased zinc on germ cells. This study assessed possible effects of zinc deficiency on Sertoli cell number and ultrastructure.Long-Evans dams and their newborn litters were placed on zinc deficient (ZD), pair-fed or ad libitum fed (AL) diets. All dams received a 20% egg white based diet containing less than one ppm zinc. ZD dams received distilled, deionized water (<1 ppm ZN), while PF and AL dams received the above water fortified with 25 ppm zinc. Male pups were sacrificed day 10 and their testes were processed for light (LM) and transmission electron microscopy (TEM).LM cell counts were performed on one (mu)m sections. Average number of germ cells on the basement membrane (BM) (=GC2) per tubular cross-section was reducted by two-thirds in ZD and PF compared to AL animals (p < 0.0001). Average number of germ cells not on the BM (=GC1) and average number of Sertoli cells per tubular cross-section were not statistically different in the three diet groups.Volume fractions of TEM subcompartments/total cytoplasm were determined by morphometric methods. The lysosome-like fraction was doubled in ZD and PF compared to AL animals (p < 0.05). Endoplasmic reticulum, Golgi and mitochondrial fractions were not statistically different in the three diet groups.Five day old Sertoli cell cultures derived from ZD, PF and AL pups were volumetrically analyzed as in vivo. The endoplasmic reticulum fraction was approximately 100% lower in ZD- than in AL-derived cultures (p < 0.01). Golgi, mitochondrial, dense body and inclusion body fractions were similar in ZD-, PF- and AL-derived cultures.These data suggest that Sertoli cells, although not significantly reduced in number in ZD and PF animals, were affected ultrastructurally by dietary treatment. The volumetric increase in lysosome-like bodies in vivo suggested that Sertoli cells participate in phagocytosis of germ cells degenerating as a result of dietary treatment. The decreased ER volume fraction of ZD-derived tissue cultured Sertoli cells suggested that Sertoli cell secretory potential may be altered as a result of zinc deficiency.

A Cluster Analytic Study In Intercultural Communication Of Rokeach's Intrumental Values Among Lds Returned Missionaries, Lisa Bradford

Theses and Dissertations

Although much has been done in the study of values several important questions relative to the study of values remain. This thesis discusses the questions of what happens to the value systems of those who leave their culture for extended periods of time, do the perceptions of value systems become more accurate after exposure, and how does religiosity affect value systems.

The study was based on the idea that each of the cultures being tested (Latin and United States) had a distinct, general value system which differentiated it from the other and yet unified the individuals within it. In this …

Judicial Prosecution Of Prisoners For Lds Plural Marriage: Prison Sentences, 1884-1895, Rosa Mae Mcclellan Evans

Theses and Dissertations

The practice of polygamy among the Mormons during the nineteenth century was vigorously prosecuted by the federal government in response to the demands of those whose political and economic goals could best be served through exploitation of the national attitude toward polygamy. Hundreds of men served prison terms for practicing what they believed was their religious obligation. This study of the sentences from the prison admission records has focused on the comparative severity of the judges, examines age as an influencing factor in sentencing, and compares the sentences of the polygamists with those for crimes against person and property.

The Effects Of War As A Basis To Consider Six Novels By Ernest Hemingway And F. Scott Fitzgerald, Nancy Weston Noel

Theses and Dissertations

Curiously, the issue of war has never been considered a solid basis for examining the works of Ernest Hemingway and F. Scott Fitzgerald. Yet one common thread running through the body of their work is war. A study of the authors’ attitudes toward war and their characters’ responses to war in Hemingway’s A Farewell to Arms (1929), For Whom the Bell Tolls (1940), The Sun Also Rises (1926), and Fitzgerald’s This Side of Paradise (1920), The Great Gatsby (1925), and Tender Is the Night (1934), yields several conclusions. Hemingway’s and Fitzgerald’s works reveal two different types of human responses to …

The Synthesis And Characterization Of Some Thermally Stable Polypyrazoles And Acetylene Terminated Aspartimides, John W. Connell

Theses and Dissertations

Reactions involving the nucleophilic addition cyclization to activated acetylenes have been employed as a novel route to moderate to high molecular weight polymers. Polypyrazoles (PI to P12) have been prepared from the Michael-type addition cyclization of various aromatic dihydrazines to aromatic dipropynones in m-cresol. The aromatic dihydrazines employed were 4, 4'-dihydrazinodiphenyl ether (4,4' -DHDPE), 4,4 '-dihydrazinodiphenylmethane (4, 4'-DHDPM), and 4, 4' -dihydrazinodiphenyl sulfone (4,4'-DHDPS). The dipropynone sutilized were 1,1’- (1,4-phenylene) bis (3-phenyl- 2-propyn-l-one), (l,4 -PPPO), 1,1’ - (1, 3-phenylene) bis (3 -phenyl- 2 -propyn-l-one), (1,3-PPPO), 1,1 '-(1,4 -phenylene) bis (2 -propyn- l-one), (1,4 -PPO), and 1,1’- (1,3 -phenylene) bis (2 …

Origin And Stratigraphy Of Holocene Sediments, Souris And Des Lacs Glacial-Lake Spillways, North-Central North Dakota, William M. Boettger

Theses and Dissertations

In the past few years, a new interpretation of the formation of the Souris and Des Lacs glacial-lake spillways has been proposed. Now, based on geomorphological evidence, it is concluded that the Souris and Des Lacs Valleys were formed by massive glacial-lake outburst floods at the end of the late Wisconsinan deglaciation. Five phases of drainage have been recognized with the first forming the Des Lacs Valley and the other four associated with drainage in the Souris Valley from different proglacial lakes in Canada. The last of these floods down the Souris Valley was the most erosive.

This study is …

The purposes of this study were (1) to determine parental attitudes concerning education vouchers and the Minnesota Postsecondary Enrollment Options Act, and (2) to examine evidence concerning the impact the Minnesota Postsecondary Enrollment Options Act will make on educational choices for parents.A random sampling of participating and nonparticipating eleventh- and twelfth-grade public school parents from twelve northwestern Minnesota counties were mailed a questionnaire which had been developed to elicit answers relating to the Minnesota Postsecondary Enrollment Options Act. The data …

Antifreeze Production And Cold-Tolerance In Overwintering Purple Martin Fleas, Ceratophyllus Idius Jordan And Rothschild (Cryo-Protectants, Hardiness)., Douglas P. Schelhaas

Theses and Dissertations

Ceratophyllus idius is an ectoparasite of purple martins (Progne subis) and commonly inhabits the nest material of these birds. In the Upper Midwest, purple martins migrate in late August and return in mid- or late April. Despite the host's absence and harsh northern winters, a portion of the adult flea population survives to reinfest returning birds. This study was designed to: (1) examine the possible roles of sorbitol and trehalose as biological antifreezes; (2) confirm the role of glycerol as an antifreeze; (3) monitor glycogen and glycerol levels and supercooling points from autumn until spring; (4) determine the temperature stimulus …

Children's Perceptions Of Social Studies: A Descriptive Study Of The Social Studies Experiences Of Selected Fifth And Sixth-Grade Students., Stephen Ellis Hornstein

Theses and Dissertations

Although there is much research on classroom practices in social studies there is little if any research which describes day-to-day life in social studies classrooms and none at all which describes it from students' perspectives. The intent of this study is to describe social studies instruction from students' perspectives, to document students' attitudes about social studies instruction and to formulate hypotheses about the causes of student attitudes based on children's descriptions and reported attitudes.Thirty-six fifth and sixth grade students were interviewed for the study. The interview consisted of eleven open ended questions designed to elicit descriptions of social studies instruction …

Vasopressin Analogues And Their Effects Upon Arousal, Attention And Memory., Deborah Iilene Couk

Theses and Dissertations

The effects of two vasopressin analogues, arginine vasopressin (AVP) and desmopressin acetate (DDAVP), upon various aspects of arousal, attention and memory were examined in this study. Sixty-two male college students were treated intranasally with either AVP (24 IU), DDAVP (24 IU), or saline. Arousal, attention and memory measures included: the Thayer Activation-Deactivation Adjective Check List (AD-ACL), the Eysenck Personality Inventory Introversion-Extraversion scale, diastolic and systolic blood pressure, pulse rate, respiration rate, digit span, a Sternberg Item Recognition Task, immediate free-recall, delayed free-recall, and recognition. Treatment with vasopressin affected AD-ACL scores, pulse rate, rate of respiration, and motor-responsivity, all of which …

Deflation Basin Stratigraphy: Southwestern North Dakota, Robert E. Seidel

Theses and Dissertations

The goal of this study was the determination of a similar depositional sequence for sediments from a number of shallow basins in southwestern North Dakota and the comparison of this sequence with other work either in the area or in similar geographic environments.

Samples were obtained by augering, coring, and trenching selected basins. They were analyzed by means of: core description; detailed texture analyses on selected cores by sieve, pipette, and SediGraph techniques; and mineralogy by x-ray diffraction. Computer analyses were used to characterize grain-size distributions and to correlate texture and mineralogy by cross-association.

The results of the study verified …

Contaminant Migration Of Oil-And-Gas Drilling Fluids Within The Glaciated Sediments Of North-Central North Dakota, William A. Beal

Theses and Dissertations

A common practice during oil and gas well-site reclamation in North Dakota is to bury the drilling muds in shallow trenches near the borehole. These muds are saltwater based (between 100,000 and 300,000 mg/L of NaCl) and can contain high concentrations of chromium, lead, and other. toxic trace metals.

Two reclaimed oil and gas well sites were chosen for study in north-central North Dakota: the Winderl site in southeastern Renville County, and the Fossum site in west-central Bottineau County. The Winderl oil well was drilled in 1959, and the drilling fluids were disposed of in a shallow pit excavated in …
