Mechanisms Of Tolerance To The Effects Of Clozapine And Pimozide On A Multiple Fixed Interval 60-Second Fixed Ratio-30 Food Reinforcement Schedule In Rats, Heidi Freese Villanueva

Theses and Dissertations

This study examined the behavioral and biochemical effects of two neuroleptic drugs. Clozapine (10 mg/kg), an atypical neuroleptic, and pimozide (1 mg/kg), a typical neuroleptic, were administered acutely, chronically (10 days), or in a behavioral tolerance paradigm (9 days of post-session administration followed by 10 days of presession administration) in order to assess the mechanisms of tolerance. Behavioral Effects were measured on a multiple FI 60-second FR-30 operant response schedule; HPLC was used to measure the biochemical effects of clozapine in the blood plasma, frontal cortex and striatum.

Presession administration of clozapine and pimozide both produced initial disruptions of response …

Modeling The Determinants Of Hospital Mortality, Abdolmohsin S. Al-Haider

Theses and Dissertations

This study examined hospital characteristics that affected the differential in hospital mortality, while controlling for the effect of community attributes. Analytical models for the determinants of hospital mortality were formulated and validated through an empirical examination of 243 hospitals that had higher or lower mortality rates than expected for Medicare beneficiaries. The dependent variable for this study was death rates for 1984 Medicare patients in united states hospitals released in 1986 by the Health Care Financing Administration.

Structural equation models that portray the causal relation between organizational constructs and hospital mortality rate were formulated. This causal model was empirically validated. …

Federal Narcotic Violators And The Dispositions Received Through The Courts With An Emphasis On Cocaine Offenders, Phyllis Rena Baker

Theses and Dissertations

The United states has been plagued with the problem of illicit drug use for many years. Drug abuse has continued to increase and is prevalent among all races and social classes of people. The question is what efforts have been or are being made in order to deter the influx of drugs into the country along with stopping the suppliers of these drugs and what has hindered the effectiveness of these efforts.

The theory of deterrence was applied to this problem because the model presumes that the punishment of criminal acts could deter potential offenders by making the negative consequences …

Perceived Stressors Of Hospitalized Antepartal Adolescents, Rita Murphy Ciavarelli

Theses and Dissertations

The purpose of this study was to explore and describe adolescents' perception of stress during antepartal hospitalization. The research questions answered in this study were: 1. What are the perceived stressors of hospitalized antepartum adolescents? 2. Are there differences in the perceived stressors among early, middle, and late adolescents?

The study was conducted in a teaching hospital in the southeastern United States. A convenience sample of 14 adolescents participated in this study. The ages of the subjects ranged from 14 to 19 years old, with the majority of the subjects 16-19 years old. The subjects were all unmarried and had …

Glucocorticoid-Responsive Hepatic Cytochromes P-450 In The Rat: Multiplicity And Differential Regulation, Keith Alan Hostetler

Theses and Dissertations

The multiplicity of glucocorticoid-responsive hepatic cytochromes P-450 in the rat was investigated by developing a series of monoclonal antibody probes directed against purified steroid-inducible isozymes from the rat (P-450p) and man (HLp). Two antibodies, termed 1G8 and 13-7-10, showed unique specificity for purified cytochromes P-450 upon immunoblot analyses. These antibodies were further characterized in terms of their reactivity toward proteins in liver microsomes from untreated and xenobiotic-treated rats. Three P-450p-related proteins were identified using 1G8 and 13-7-10 to monitor the expression of P-450p family subtypes. In untreated rats, members of this family exhibited sex-specific expression. Treatment with various chemicals resulted …

The Effect Of Pre-Emergence Gastric Aspiration On Postoperative Nausea And Vomiting Following Abdominal Surgery, Marc Alan Friedberg

Theses and Dissertations

An investigation was undertaken to determine the effect of pre-emergence gastric aspiration on the incidence of postoperative nausea and vomiting in abdominal surgery patients. Thirty female ASA I and ASA II patients were randomly assigned to either a control group (n = 16) or a treatment group (n = 14). Those patients in the treatment group received pre-emergence gastric aspiration with a suction catheter; those patients in the control group did not. The incidence of postoperative nausea and vomiting was determined at various time intervals. Data were analyzed using Student's t test and the Chi-square statistic. Results indicated that there …

The Relationship Between Position And Incidence Of Spinal Headache Following Spinal Anesthesia In The Young Adult Female, Royce A. Fishell

Theses and Dissertations

This investigation determined the difference in the incidence of spinal headache in 33 patients placed in 30 degrees (°) head-up position versus 33 patients who remained flat for four hours following the administration of spinal anesthesia. An experimental design was used. The two randomly assigned groups presented for elective postpartum tubal ligation under spinal anesthesia. Group A was placed flat and group B had the head of their beds elevated 30° postoperatively. Strict procedural protocol was adhered to prior to and during the administration of the spinal anesthetic. To determine if the patients had any symptoms consistent with spinal headache, …

Sociometric Categorization Of Children: An Empirically Based Method, Robert S. Falk

Theses and Dissertations

The use of sociometric assessment as a method for investigating the social competence of children and the prediction of future adjustment difficulties was reviewed. Recent methods used to form up to five sociometric groups (Popular, Average, Rejected, Neglected, and Controversial) were surveyed.

Various combinations of raw scores, standard deviation units, standardized scores, and binomial probability scores have been used in classification procedures. lnclusion/exclusion criteria, or cutoff scores, have been based on arbitrary statistical decisions regarding the ”extremeness" of children’s statements (positive and negative nominations) regarding their peers. These aspects of sociometric categorization result in limitations on the validity and generalizability …

Pressure-Solution Features Of The Birdbear Formation (Devonian), Williston Basin, North Dakota, James C. Collier

Theses and Dissertations

Pressure-solution features of the Birdbear Formation (Devonian), Williston Basin, North Dakota were the subject of this study. In the area studied, the Birdbear Formation is primarily a limestone with mud-rich textures. The investigation contained three principal phases: 1) a study of the parameters influencing the size and shape of the pressure-solution response, 2) the process of reactate dolomite formation and its relation to calcite neornorphism, and 3) the relation of neomorphism to pressure solution.

The principal pressure-solution response types are stylolites and solution seams. Stylolites are pressuresolution seams with a tooth-and-socket, serrated shape. Pressure-solution seams are gently undulating to smooth …

Thermal History Model Of The Williston Basin, Yue-Chain Huang

Theses and Dissertations

The factors that affect the subsurface temperature of a sedimentary basin were investigated by empirical and analytical methods. A review of thermal-mechanical models suggests that the Williston Basin was formed by more than one mechanism. The Williston Basin may have been initiated by a thermal event followed by thermo-flexural or phase transition subsidence.

The heat that initiated the formation of the Basin was significant to the thermal history of the Basin at its very beginning stage. However, most of the anomalous heat would have dissipated before the deposition of Bakken Formation 363 Ma ago. The heat flow history of the …

Proterozoic Structures In North-Central North Dakota: A Gravity Study, Kathryn C. Luther

Theses and Dissertations

The purpose of this study was to determine the structure of the contact between the Superior Craton and the Trans-Hudson orogenic belt in north-central North Dakota between latitude 48 and 49 degrees north and longitude 100 and 102 degrees west, using gravity modeling. Major structural and geochronologic boundaries beneath the eastern flank of the Williston Basin in North Dakota and southern Canada appear as coherent patterns on a Bouguer gravity map.

The contribution of the Phanerozoic overburden (density assumed to be 2 . 48 g cm- 3 ) to the gravity signal, was removed, leaving residual gravity anomalies due to …

Sedimentology And Stratigraphy Of Glacial Lake Souris, North Dakota: Effects Of A Glacial-Lake Outburst, Mark L. Lord

Theses and Dissertations

Glacial-lake outbursts commonly occurred along the southern margin of the Laurentide Ice Sheet as ice-marginal lakes suddenly drained. These outbursts released huge volumes of water with tremendous erosive potential, forming large trench-shape channels. Although glacial-lake spillways have been studied in detail, the effects of outbursts on downstream lakes have not. The purpose of this study was to demonstrate the effects of the Glacial Lake Regina outburst on the lake that received the flows, Glacial Lake Souris.

Glacial Lake Souris, located in what is now North Dakota, was inundated by about 74 km3 of water carrying 25 km3 of sediment from …

Deposition And Diagenesis Of A Portion Of The Frobisher-Alida Interval (Mississippian Madison Group), Wiley Field, North Dakota, Mark R. Luther

Theses and Dissertations

This study focused on the Frobisher-Alida interval, in particular, the Glenburn bed or the Mississippian Mission canyon Formation. Wireline logs and cores from closely spaced wells in, and adjacent to, the Wiley Field, Williston Basin, North Dakota were examined. Information derived from the wireline logs was used to construct several maps which show that there was little or no topographic relief or slope in the study area during deposition or the Glenburn bed. In addition, the maps show that structural derormation occurred subsequent to deposition or the Frobisher-Alida interval.

Six distinct lithoracies were recognized in cores or the Glenburn bed …

Characterization And Utilization Of High- And Low-Sodium Lignite Of The Beulah-Zap Bed (Paleocene), Indian Head Mine, Southwestern North Dakota, Gale G. Mayer

Theses and Dissertations

A study of high- and low-sodium lignite of the Beulah-Zap bed sampled at the Indian Head Mine, Pit 11 and 12, respectively, in Mercer County, North Dakota and fly ash derived from utilization tests on the lignite, indicates the fly-ash composition and related utilization potential can be correlated to coal geochemistry.

Average lithotype abundances for each of the sampling sites were estimated to be vitrain 50%, attritus 45%, and fusain 5%. Attritus occurs more frequently in the upper part and vitrain in the middle and lower parts of the seam. Maceral groups, identified microscopically, were (in order of decreasing abundance): …

Macropaleontology Of The Gunn Member, Stony Mountain Formation (Upper Ordovician), Manitoba And North Dakota, Frederick K. Lobdell

Theses and Dissertations

The Gunn Member of the Stony Mountain Formation has long been known to contain an abundant and diverse fauna. This study was undertaken to identify and describe the macrofauna of the Gunn Member in the subsurface of North Dakota, previously neglected.

As a necessary first step, collections of fossils from outcrop were examined and identified. With the outcrop fauna serving as a reference collection, twenty cores from the North Dakota subsurface were examined, described, and their fossils sampled. Fossil and sediment samples were washed and sieved and the residues were picked for microscopic representatives of phyla usually considered to be …

Stratigraphy And Depositional History Of The Deadwood Formation (Upper Cambrian And Lower Ordovician), Williston Basin, North Dakota, Douglas B. Anderson

Theses and Dissertations

Based on gamma-ray characteristics, the Deadwood Formation is divided into six informal, attribute-defined units, members A through F. Members A and Bare Late Cambrian in age; members C through Fare Early Ordovician in age. The type section of the Deadwood, in the northern Black Hills, is dominated by Upper Cambrian strata. Much thicker Lower Ordovician rocks occur in the deeper portion of the Williston Basin.

The Deadwood comprises the Sauk sequence and represents the initial Paleozoic transgression or the seas on the North American craton. Eight smaller-scale transgressive-regressive events occurred on the craton during the Late Cambrian and the Early …

The Effect Of Man On The Landscape And The Effect Of Land On The Manscape: Or Contingent Plans For Knowing A Mountain, Taylor Scott Baldwin

Theses and Dissertations

In my artistic practice, I emphasize personal and pan-cultural anxieties regarding civilization and the environment as an impetus for work in sculpture, video, and drawing. By locating marginal microcosmic subject matter that tellingly exhibits macrocosmic global dread, I seek to capture and distill our overwhelming eco-socio-political anxiety into a portrait of a society at a point in its history when the specter of nameless impending disaster weighs pressingly on the collective psyche. This thesis is supplementary to my work of sculpture in the Graduate School of the Arts Thesis Exhibition at the Anderson Gallery opening on April 27th, 2007. The …

Work Energy And The Character Of Organizations: An Orgonomic Framework For Organization Development, Martin D. Goldberg

Theses and Dissertations

To date, the field of organization development (OD) has lacked the kind of unifying approach to theory and practice that would enable it to be considered a discipline. The present study, in conception and methodology, commences building a unified framework for OD based on the work of psychiatrist and natural scientist Wilhelm Reich (1897-1957). By conceptually merging the field of OD with the science of orgonomy, that body of knowledge based on Reich's discoveries, this project lays the foundations for a comprehensive theory that can lead to greater understanding of the nature, development, and functioning of organizations, a theory with …

Cohesion In A Utah Sample Of Latter-Day Saint Couples, Joe Edgar Glenn

Theses and Dissertations

It was hypothesized by Olson and his colleagues (Olson, et al., 1983) that "Mormons" were more likely to be enmeshed than many other cultural/religious groups. The purpose of this study was to determine if individuals affiliated with the Church of Jesus Christ of Latter-day Saints (Mormon) scored significantly more often in the enmeshed category of the cohesion dimension of the Circumplex Model, using FACES III data, than the norming sample for the FACES III instrument. The study also examined the level of satisfaction that the Mormon sample expressed for their level of cohesion. Data from 61 L.D.S. married couples living …

The Test Of English As A Foreign Language Sample Test As A Measure Of Adolescent Language Ability, Paul Gardiner Osborn

Theses and Dissertations

Relative performance on the Test of English as a Foreign Language Sample Test (TOEFL-ST) was explored in sixty native English speaking high school students. Subjects also were administered the Fullerton Language Test for Adolescents and the Peabody Picture Vocabulary Test Revised. The TOEFL-ST was not difficult for this population, indicating that TOEFL tests taken by foreign speaking college students probably assess a level of native English competency well below the high school level. The three tests, including subtests, appear to measure a wide array of subdomains of language competency. The data do not support the conclusion that any of these …

Hydrogeology Of The Hillsboro Landfill, Hillsboro, North Dakota, Jeffrey D. Maletzke

Theses and Dissertations

Landfills are the primary means for land disposal of solid wastes, and as such, they represent potential sources of groundwater contamination. This potential for contamination is exemplified by the Hillsboro landfill, which was emplaced above the Hillsboro aquifer, within permeable surface materials, and under shallow water-table conditions. Burial of refuse in trenches 15-feet (4.57 m) deep ensure that at least portions of the refuse are below the water table, which varied from 5.4 to 13.2 feet (1.7 to 4.0 m) below the surface. Concern over these factors led to the present study.

Subsurface conditions were investigated by electrical, earth-resistivity surveying. …

A History Of The Men's Intramural Program At Brigham Young University, David A. Brown

Theses and Dissertations

The purpose of this study was to compile and present an organized and complete history of the Men's Intramural Program at Brigham Young University.

The Brigham Young University Intramural Program had its beginning early in Brigham Young Academy history. The intramural program originated as an outgrowth of the physical education instructional program. Prior to 1954 the intramural program was part of the Physical Education Department and the Chairman of that department gave leadership to the intramural program by assigning part-time directors and student managers to organize sporting events. Since 1954 a full-time director has been employed as Intramural Director. The …

A Demographic Examination Of Household Heads In Salt Lake City, Utah, 1850-1870, Larry W. Draper

Theses and Dissertations

This study examines the demographic characteristics of household heads in Salt Lake City, Utah at three points in its history: 1850, 1860, and 1870. Data was compiled on population growth, nativity, sex, age, occupation, wealth, and persistence from the United States Census for those years.

The data shows that between 1850 and 1870 the makeup of Salt Lake City household heads changed dramatically from predominately American-born to predominately foreign-born. This change in the nativity of household heads over time significantly influenced several demographic characteristics including the location of immigrant settlement, occupational tendencies, and a high level of stratification of real …

Couple Cohesion: Differences Between Clinical And Non-Clinical Mormon Couples, Colleen Margaret Peterson

Theses and Dissertations

This thesis examined the differences between 30 clinical and 30 non-clinical Mormon married couples on the perceived and ideal cohesion scores on the FACES III family typology instrument. Two three-way analyses of variance were done to examine these differences. the results provided evidence that there were significant differences between cohesion scores in clinical and non-clinical couples Both the clinical and non-clinical ideal scores fell close to the enmeshed end of the cohesion dimension of the Circumplex Model. The mean perceived cohesion scores, however, showed a difference between the clinical and non-clinical couples. The clinical couple mean scores fell in the …

County-Level Land Use Planning Policies And Regulations Impacting The Pattern Of Settlement In Utah County, Utah, Erik A. Johnson

Theses and Dissertations

Utah County has the second largest county population in the State of Utah and ranks 16th out of 29 in total land area. Over 90% of the County's quarter of a million residents live in the area known as Utah Valley, a relatively narrow strip of land situated between the Wasatch Mountains and Utah Lake. In addition to a large population, most of which was realized during the 1970s, Utah Valley also contains the bulk of the County's important agricultural land. Not surprisingly, the expanding population in Utah Valley has created competition between agricultural and urban uses for limited land …

The First London Mormons: 1840-1845: "What Am I And My Brethren Here For?", Lynne Watkins Jorgensen

Theses and Dissertations

Historians have determined that the visit to London by the early missionary-apostles of the Church of Jesus Christ of Latter-day Saints was the greatest disappointment of their proselyting careers. This thesis shows that, though the mission to London was not numerically successful considering the potential conversion, it appealed to the dynamic, energetic, "middling-class" religious seeker who was produced by the strong nonconformist movement indigenous to London. A specific nonconformist group is identified as responding to the preaching of the early apostles. This thesis demonstrates that those few converts kept the Church alive in London during difficult years. It also shows …

The Convert As A Social Type: A Critical Assessment Of The Snow-Machalek Conversion Typology As Applied To British Mormon Converts, Joy A. O'Banion

Theses and Dissertations

The study was designed to be a critical assessment of the Snow-Machalek Conversion Typology. Data were collected from Mormon converts in the British Isles, and an attempt was made to apply the typology to these converts. It was assumed that if the typology could be effectively applied to Mormon converts, strong correlations would be found between its dimensions and quantitative measures of conversion. It was also assumed that social integration of converts would play an important part in the conversion process.

The application of the typology proved to be very difficult; however, some dimensions seemed to be more useful than …
