Identity And Language: Roxy In Mark Twain's Pudd'nhead Wilson, Mary Frances Johnson

Theses and Dissertations

The literary dialect of Mark Twain's Pudd'nhead Wilson goes relatively unnoticed by scholars since it does not seem as interesting as the literary dialect of his masterpiece Huckleberry Finn, There seem to be only two distinct dialects in Pudd ' nhead W1.1 son (as compared to Huckleberry Finn's seven to nine); one spoken by the whites and one spoken by the blacks. Almost all of the black dialect is spoken by one character, Roxy, the slave woman who is legally black but white in appearance. A closer look at Roxy's dialect can determine language characteristics, along with important matters of …

The Effects Of Religious Affiliation And Attendance On Illicit Sexual Behavior And Substance Abuse, Thomas W. Zane

Theses and Dissertations

A sample of 7724 college students in Washington and Utah was selected to study the relationships of religious activity and religious affiliation to illicit sexual behaviors, use of marijuana, and getting drunk. For all religious affiliations (except for the Jews), there were significant correlations between church activity and the measured illicit behaviors. LDS rates of behavior were significantly lower at <.001 for the five illicit behaviors. Two factor analyses were calculated to determine which sexual behaviors would load on a single factor and which substances would load on another factor. Extramarital coitus, heavy petting, and passionate kissing formed the first "sexual" factor. The use of beer, liquor, and marijuana combined with the behavior getting drunk to form the "substance-abuse" factor. A canonical analysis reported a moderate relationship with a canonical coefficient of .534 between the two factors. A discriminant analysis based on each subjects' religious affiliation and activity level yielded a 70-80 percent correct classification percentage.

Designing A Relational Data Base For A Problem Solving Environment, Kathryn S. Dawson

Theses and Dissertations

When choosing a system design in which to solve a recurring problem which depends on interrelated data a relational data base environment should be considered. The original problem can be solved through this design and by allowing users to view the data in the relational constructs the data can be easily used in numerous other applications. Theoretical support insures the design is sound avoiding inaccurate results. Independence between the logical and physical views of the data enables the data base administrator to adjust the physical data structures in order to optimize system performance without affecting existing user applications.

The chemical properties of these molybdenum complexes are compared with those which possess tridentate (ONO) Schiff base ligands. Cyclic voltammetry was used to obtain cathodic reduction potentials (E_PC) for the quasi-reversible reduction of the cis-dioxomolybdenum (VI) complexes. Although the reductions are quasi-reversible, trends are observed in E_PC both within series and when different series are …

A Descriptive Study Of The Relationship Of Teaching Level And Subject Area Assignment To Teachers' Attitudes Toward Critical Thinking, Patricia Barnes Walker

Theses and Dissertations

This study describes teachers' attitudes toward critical thinking: their definitions of critical thinking, the importance of critical thinking in their daily lives, how important it is to them that their students use critical thinking in class, whose responsibility it is to teach critical thinking, and who or what has influenced their attitudes about critical thinking. Each of these aspects of critical thinking was analyzed by teaching level (elementary, middle, or high school) and by subject area assignment (English, social studies, mathematics, science, and "other") to determine if relationships exist between these attributes and attitudes toward critical thinking.

Alterations In Blood-Brain Barrier Function Following Acute Hypertension: Comparison Of The Blood-To-Brain Transfer Of Horseradish Peroxidase With That Of Alpha-Aminoisobutyric Acid, Mary Draper Bennett Ellison

Theses and Dissertations

The blood-brain barrier (BBB) selectively restricts the blood-to-brain passage of many solutes owing to unique properties of cerebrovascular endothelial cell membranes. This selective blood/brain interface participates in the maintenance of brain homeostasis by controlling nutrient, gas, and fluid exchange necessary for brain function. Normal BBB function can be altered under various pathological and experimental conditions, allowing the transfer into brain parenchyma of blood-borne solutes normally excluded. To date, experimental study of the BBB has been accomplished primarily through the use of two different methodological approaches. Some investigators have focused on the barrier's morphological correlates and its morphopathological alteration under various …

Middle And Late Wisconsinan (Pleistocene) Insect Assemblages From Illinois, Kristine D. Carter

Theses and Dissertations

Two highly organic sediment sequences from central and western Illinois (the Athens North Quarry and Biggsville sites, respectively) of Middle and Late Wisconsinan age were studied to gain knowledge about the environment and climate of this area during the time immediately prior to the maximum extent of the last glaciation. Paleoenvironmental and paleoclimatic inferences are based principally upon knowledge of the habitat preferences and geographic distributions of extant species of beetles that are represented as fossils. These data are supplemented by information from sedimentological and taphonomic studies and from previously published palynological and plant-macrofossil studies.

Palynology Of The Hagel Lignite Bed And Associated Strata, Sentinel Butte Formation (Paleocene), In Central North Dakota, Edward N. Steadman

Theses and Dissertations

The Hagel bed is an economically important lignite and is the lowest named lignite in the Sentinel Butte Formation, Fort Union Group. The Hagel bed extends throughout the Knife River Basin coal-mining area of central North Dakota. Stratigraphic sections of the Hagel bed, including intercalated clastic rocks, were measured in the highwalls of the Center mine, Glenharold mine, and Falkirk mine.

Samples from the stratigraphic sections were described and analyzed, using standard palynological techniques, for their palynomorph content. Palynomorphs proved to be well preserved and abundant. Maceration of Hagel bed samples yielded a diverse collection of palynomorphs. A total of …

Petrology Of The Beulah-Zap Lignite Bed, Sentinel Butte Formation (Paleocene), Mercer County, North Dakota, David R. Kleesattel

Theses and Dissertations

The Beulah-Zap lignite bed is one of several economically important lignites in the Sentinel Butte Formation (Paleocene). This lignite occurs as a subsurface unit in the Knife River Basin of Mercer and I Oliver counties of North Dakota. The Beulah-Zap lignite is a heterogeneous carbonaceous rock unit composed of megascopic and microscopic I components, which are lithotypes and macerals, respectively. Relationships between the maceral contents of the lithotypes follow patterns similar to those of bituminous coals. Coal petrology, the study of maceral and lithotype occurrence and I distribution, was applied to determine: 1) mode of coalification, and 2) depositional environment …

The Geology And Hydrocarbon Potential Of The Dawson Bay Formation Carbonate Unit (Middle Devonian), Williston Basin, North Dakota, Wayne R. Pound

Theses and Dissertations

The Middle Devonian Dawson Bay Formation carbonate unit is present in the subsurface of North Dakota except where truncated by post-depositional erosion. The carbonate unit thickens from the erosional limit to a maximum thickness of 47.5 m (156 ft.) in Renville County and reaches a maximum depth of 3798 m (12, 432 ft.) below the surface in McKenzie County. In North Dakota, a submarine hardground separates the carbonate unit from the underlying “Second Red Bed member” of the Dawson Bay Formation. The upper contact with the Souris River Formation is conformable except in those areas where the Dawson Bay Formation …

Petrology Of The Sentinel Butte Formation (Paleocene), North Dakota, Nels F. Forsman

Theses and Dissertations

Sedimentary materials of the Sentinel Butte Formation have been petrographically examined using optical and scanning electron micro scope/microprobe techniques. The formation consists of fine-grained materials which generally are classified mineralogically as volcanic litharenites or feldspathic litharenites. Most rock units in the formation are siltstones and mudstones. Multiple source rock types, including volcanic, metamorphic, and sedimentary, are represented by mineralogic constituents, but volcanic rock fragments are most abundant. Petrographic distinctions between basal and uppermost sandstone units suggest that a change in sediment supply took place near the end of Sentinel Butte time. Authigenic cement development appears concentrated in more porous and …

A Quantitative Analysis Of Shoreline Erosion Processes, Lake Sakakawea, North Dakota, Mark D. Millsop

Theses and Dissertations

Shoreline erosion is a problem at Lake Sakakawea and Lake Audubon, North Dakota. Land is lost, water quality is adversely affected, and reservoir storage capacity is decreased.

Instrumentation of the eastern shores of both lakes began in 1983 to quantify bank erosion by process (e.g., wave erosion, rainsplash and runoff, and frost-thaw failure). Other data gathered included: pool level fluctuations; wind velocity, direction, and duration; precipita tion; soil moisture; frost penetration; freeze-thaw cycles; and geology (e.g., texture, clay mineralogy and structure).

The magnitude of shoreline erosion is highly variable, especially within Lake Sakakawea. For the interval of May 1983 through …

Late Quaternary Environmental And Climatic History Of The Southern Chilean Lake Region Interpreted From Coleopteran (Beetle) Assemblages, John W. Hoganson

Theses and Dissertations

A diverse Coleoptera fauna of 462 species in 48 families was collected from 41 locations in the Parque Nacional de Puyehue and adjacent parts of the Lake Region of southern Chile. The sample locations ranged from rain forest habitats at sea-level to Andean tundra habitats at 1500 m msl. Cluster analysis of a Dice similarity coefficient matrix revealed a broad pattern of bioassociations within the large data base, Boundaries between the bioassociations correspond largely with those of the major vegetation zones implying that the distribution of the fauna is strongly influenced by the distribution of plants. Evidence from fossils indicates …
