Metamorphism In The Eastern Lac Seul Region Of The English River Subprovince, Ontario, Steve J. Chipera

Theses and Dissertations

The English River subprovince of the Superior Province, Canada, is a linear, east-west trending high-grade metamorphic belt which extends from Lake Winnipeg in the west, to the James Bay lowlands in the east. It is composed of two prominent lithologic domains: a northern sedimentary gneiss-migmatite domain, and a southern plutonic domain. The northern domain consists primarily of alternating migmatized layers of garnet-biotite "wacke" and garnet-cordierite-biotite "pelitic" metasediments. The southern domain is composed mainly of intermediate granitic to trondhjemitic plutons. Bordering to the north and south are the lower grade Uchi and Wabigoon greenstone belts. Metamorphism and migmatization occurred during the …

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 …

Theses and Dissertations

The Frobisher-Alida interval is a subsurface, marker-defined unit, one of several units designated for rocks of the Madison Group (Mississippian) in the Williston Basin of North Dakota. The Frobisher Alida conformably overlies the Tilston interval and is conformably overlain by the Ratcliffe interval. 1t attains a maximum thickness of a little over 400 feet (123 m) and thins to an erosional edge along the eastern margin of the Basin.

The Frobisher-Alida is composed of limestones, dolomitic limestones, and dolostones of the Mission Canyon Formation and anhydrites of the overlying Charles Formation which exist in a complex facies relationship within the …

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 …

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 …

Macrofossils And Biostratigraphy Of The Bakken Formation (Devonian And Mississippian) In Western North Dakota, Lawrence C. Thrasher

Theses and Dissertations

The Bakken Formation, up to 145 feet thick in North Dakota, is a subsurface formation in the Williston Basin that typically consists of two black shale members separated by a middle member of predominantly gray siltstone or silty limestone up to 85 feet thick.

The survey responses showed no significant problem with students transferring within the state. Responses also showed that a majority of either the curriculum directors or science teachers preferred a more specific description of the State Basic Curriculum Content. The survey indicated that Life Science is taught the most often in the seventh grade …

The Relationship Between Environmental Awareness And Academic Achievement In Elementary School Children, Earl T. Leindecker

Theses and Dissertations

One hundred and seventy two sixth grade public school students were surveyed to investigate the possibility of a relationship between the children's perception of the cleanliness of the academic environment and the students' level of academic achievement. Utilizing a Pearson product-moment coefficient, student responses on a researcher-prepared Likert-type scale were correlated with the Normal Curve Equivalency Score for the reading portion of the Stanford Achievement Test. Analysis of the statistical data revealed a negative .139 correlation. The positive directional hypotheses cannot be accepted. However, the null hypothesis must be retained because of the negative .139 correlation at the .05 level …

The Ever Present Past: Thoreau's Perception And Use Of History In Walden, Kathleen Tracy Alonzo Fineran

Theses and Dissertations

The purpose of this project was to explore Thoreau's historical perspective and to examine how his perception of history is reflected in his major work Walden. Regarding the scope of the project, three dimensions of Thoreau's perception and use of history were treated: his belief in a historical continuity of experience; his belief in historical truth as myth; and his quest for the American past. Regarding the limitations of the project, Thoreau's thought and other works were only drawn upon as they served to provide a context for discussion and no effort was made to reconcile any ambiguities in Thoreau's …

An Analysis Of The Black Image In Children's Literature In Terms Of Characterizations, Illustrations, And Language, Joan Smith Dickson

Theses and Dissertations

This descriptive study analyzed two samples of children's literature to determine the frequency, if any, of negativism toward black people in terms of characterizations, illustrations, and/or language. One sample consisted of eighteen (18) books published prior to 1965 which had been removed from elementary school libraries because they were "outdated and portrayed black characters in a demeaning, stereotyped manner" (Lisby, Note 1). The second sample of twenty-five (25) books published since 1965, depicting at least one major black character, was randomly selected from elementary school libraries. The two samples of books were read and analyzed using a checklist instrument to …

The Image Of Southern Americans In Selected High School Anthologies, Betty Jenkins Aiken

Theses and Dissertations

This study was a descriptive investigation of the allocation of space to Southern writers and of the image of Southern Americans in selected high school anthologies. The materials analyzed were sixteen high school anthologies used in grades nine, ten, and eleven during the 1984-1985 school year by eight high schools operating in a system of approximately 25,000 students in the southern region of the United States. The instrument used to measure allocation of space was a simple mathematical procedure. To measure the directionality of content, frequency counts were used. The results revealed both positive and negative aspects of the textbooks …

The Effects Of Head Start On Cognitive Development, Gloria Toelle

Theses and Dissertations

The purpose of this study was to compare Head Start students with non-Head Start students in first grade to see if there were significant differences in cognitive achievement. A posttest only design was used, and a factorial analysis of variance was used as the statistical analysis at the .05 level of significance. Both sex and Head Start comparisons were made, but no significant findings were found. However, it was noted that boys who went to Head Start were able to achieve as much as the girls who did not. Since boys are usually less ready for school, the conclusion from …

"Do What The Spirit Say Do": John Beecher And His Poetry (Social Protest, Political Poetry, Alabama), James Alfred Helten

Theses and Dissertations

John Beecher lived for nearly half of the twentieth century in the vanguard of social protest in the United States. His personal protest manifested itself primarily in two arenas which are often considered to be mutually exclusive, art and politics. In neither arena was he an organization man, but rather a "free radical." He belonged to no particular school of poets, and he espoused racial equality and freedom of ideology at times when neither of those issues was popular. Beecher felt no reticence about conjoining poetry and politics, confident of the benefits that might more than offset the detrimental effects. …

Teachers' personal recollections clustered around the …

Individual Differences In Prose Memory Recall And Eeg Activation As A Function Of Personality (Arousal, Laterality, Attention), Rodney Allen Swenson

Theses and Dissertations

The present study investigated a theoretical model of neuroattentional self-control systems postulated by Tucker and Williamson (1984) by examining how the systems they outline present themselves behaviorally. One system, the Activation system, was described as functionally important for preparing the organism for maintaining a tonic, motoric readiness for action. It is complemented by an Arousal system, whose main function was to perceptually orient the central nervous system to novelty in the stimulus array. The former was postulated to be left-lateralized while the latter was said to be right-lateralized, in terms of hemispheric specialization. To examine this model, 40 subjects (20 …

High Temperature Reactions Of Bibenzyl With Elemental Sulfur And Hydrogen Sulfide In The Presence And Absence Of Hydrogen And Carbon Monoxide (Coal Model Compounds, Organosulfur Chemistry, Ipso Substitution, Hydrocracking, Pyrolysis), Robert Dale Hei

Theses and Dissertations

High temperature reactions were done with bibenzyl and related compounds to study C-C bond cleavage under coal liquefaction conditions. Reactions were run in 12-ml stainless steel, 3.7-ml glass, and 8.0-ml aluminum autoclaves designed in our laboratory. The range of temperatures studied was 250-515(DEGREES)C and that of pressure was 0-1800 psi (initial).Mechanisms for the cleavage of the aromatic-aliphatic C-C bonds ((alpha)-cleavage) and the aliphatic-aliphatic C-C bond ((beta)-cleavage) have been postulated. The two sets of conditions studied were: (i) those which included some form of sulfur, and those which excluded sulfur.With H(,2)S present, the (beta)-cleavage to toluene was extensively promoted. The rate …
