The Effects Of Conceptual Factors On Visual Masking, Damon G. Labarbera

Theses and Dissertations

Potter (1975, 1976) has shown that visual masks can exert effects both at the level of the icon and at higher levels of processing. Her methodology involved presenting pictures in a sequence at very fast rates, in order to mimic naturalistic saccadic viewing. The present study used similar methodology in order to investigate whether a picture which violates an expectation about pictures in that series exerts more of a masking effect than a picture which coincides with the expectation.

Each of 38 subjects was shown 36 sequences of eight pictures. In nine trials, every picture in the trial was drawn …

Teacher Attitudes Toward The Gifted: A Survey Of Grand Forks Elementary Schools, Carol Senger Korynta

Theses and Dissertations

This research was designed to explore the perceptions of educators in regard to the gifted. Research indicates that there are often misconceptions toward the gifted and a fear of elitism. There is an attitude that a specially gifted child can succeed without special services. However, research shows that one out of five high school dropouts are gifted indicating that the gifted do not succeed on their own. These children's needs can be nurtured through accurate identification and the provision of proper environments organized by knowledgeable educators.

A survey, Teacher Attitude Toward Gifted Education, was constructed specifically for use in this …

The Effects Of Desmopressin Acetate (Ddavp) On The Learning Of A Brightness Discrimination In Rats, Deborah Iilene Couk

Theses and Dissertations

Sixty male albino rats received DDAVP, a placebo, or control treatment and were tested on a brightness discrimination task. Three groups (DDAVP, placebo, and control) were tested in the morning and three groups were tested in the evening for possible diurnal influences of DDAVP. The acquisition and reversal of the brightness discrimination, along with the retention of the reversal problem after a five- day retention interval were analyzed. Inspection of forward and backward learning curves plotted for each task revealed facilitated acquisition along with an initial impairment of reversal learning in those animals treated with DDAVP. These results were consistent …

Use Of Indirect Services By Speech/Language Pathologists In Manitoba Public Schools, Deborah Elaine Partridge

Theses and Dissertations

Speech/language pathologists in Manitoba public schools have expressed concern about their large caseloads and their frustrations in dealing with time restrictions. Indirect services have been suggested as a means of coping with these concerns. Research has shown that indirect services such as home programs and use of paraprofessionals, volunteers, and classroom and resource teachers have proven to be especially effective.

The purpose of this study was to compile information from speech/language pathologists in Manitoba public schools concerning use of indirect services and to use this information to compare service models used by subjects working in urban and rural areas of …

Arts Education In A Teacher Education Curriculum: A Model Based On Comparative Analysis Of Arts Education Theories, Jean A. L. Olson

Theses and Dissertations

In this study the historical role of the arts in America was briefly traced as well as the history of federal interest in the arts and arts education. The importance of arts education for the individual, the school, and society was stated. Four basic tenets of arts education were derived from research and literature which provided criteria for effective arts activities and strategies. These tenets suggest that arts education (1) should be based on experiential, discovery-based, process-oriented approaches; (2) should be viewed as a developmental activity; (3) should focus on the cognitive, affective, and psychomotor domains of learning; and (4) …

Arsenic: An Analytical Procedure To Determine Its Total Content In Biological Samples And Signs Of Its Deprivation In Rats And Chicks., Eric Oliver Uthus

Theses and Dissertations

The first section of this dissertation deals with the development of a procedure for the determination of total arsenic in biological samples. Arsine generated from arsenic in dry combusted biological samples was measured by using an atomic absorption spectrophotometer equipped with a graphite furnace. Innovations of the method included the introduction of arsine into the interior of the graphite tube via one internal purge gas port only, the use of three traps to remove water from generated arsine, and the use of Erlenmeyer flasks in the generation of arsine. EDTA was added to the sample mixture to prevent interference from …

Articulation Practices In Nabte Member Institutions Regarding Shorthand And Typewriting Courses Completed In High Schools And Noncollegiate Post-Secondary Schools., Mary Hill Turner

Theses and Dissertations

The problem of this study was to identify the articulation practices in effect in NABTE (National Association of Business Teacher Education) member colleges and universities regarding students who had completed shorthand and/or typewriting courses in high schools and noncollegiate post-secondary schools before entering the teacher education program.A total of 296 questionnaires were mailed and a total of 224 usable returns were included in this study.Significant differences were found in articulation practices based on financial support, regional accreditation and AACSB/NCATE membership.While there was little evidence of the existence of statewide articulation programs, public institutions were less likely to be involved. Public …

Health Risk Appraisal And Health Promotion Behavior In Young Adults, Diane L. Hanna

Theses and Dissertations

Health Risk Appriaisal (HRA) is gaining widespread popularity as a health promotion strategy. Yet there are limited studies to date to assess the impact of HRA on health behavior, particularly among young populations. The purpose of this investigation was to determine the effectiveness of individual HRA results as a stimulus for young adults to pursue health promoting behavior. It was hypothesized that young adults exposed to the results of their personal HRA would demonstrate a significantly higher health habits change score than would young adults given the HRA, but not exposed to its results.

A pretest-posttest, control group design was …

Nuclear Envelope Proteins: Chemical Characteristics And Molecular Interactions Of The Lamins, David Lee Cochran

Theses and Dissertations

The lamins are a group of proteins in a residual nuclear envelope fraction derived from the nuclear lamina. The absence of specific functional assays for the two predominant species, lamin A and lamin B, has complicated their biochemical characterization. Initial studies reported in this work involved the enzymic cleavage of isolated lamins A and B and another lamina protein with a molecular weight of 61,000-daltons. The results obtained with each of three enzymes indicated strong similarities between the three nuclear envelope proteins.

Further chemical characterization of the lamins has been achieved. Lamins A, B and C have been separated by …

Electrochemical Determination Of The Heterogeneous Electron Transfer Kinetics Of Soluble Spinach Ferredoxin, Charlene D. Crawley

Theses and Dissertations

The application of electrochemical techniques to biological systems has become an attractive method for characterizing the redox and electron transfer behavior of biomacromolecules. This study focuses on the role of soluble spinach ferredoxin (Fd) in photosynthesis where it functions as an electron carrier to membrane bound species in the plant chloroplast. An electrochemical model is used where in Fd now serves as a soluble redox species which undergoes oxidation and reduction via electron transfer at an electrode. This type of model is significant in that both the membrane and electrode reactive sites are characterized by charged bilayer interfacial regions which …

Enflagellation Of Naegleria Fowleri, Terry Wayne Woodworth

Theses and Dissertations

Organisms of the genus Naegleria differentiate from feeding, dividing amebae into temporary swimming flagellates when deprived of nutrients. Factors critical for enflagellation of the pathogenic species, N. fowleri, were delineated and optimal conditions established for evoking reproducible conversion of N.fowleri populations. N. fowleri enflagellation differed from that of N. gruberi in its dependence upon growth phase, population density during enflagellation and in the timing and extent of the conversion. N. fowleri amebae from stationary phase cultures grown at 37°C, washed free of medium and suspended in nutrient~free ameba saline, acquired flagella and converted to mature flagellates in a synchronous manner …

Effects Of Pulsed Electric Fields On Mammalian Cell Membranes, Guy K. Smith

Theses and Dissertations

The effect of pulsed electric fields on cell membranes were studied to investigate the effects of an electric field, per se, on biological systems, without the densometric and other technical problems associated with other forms of nonionizing radiation. Exposure of mouse splenocytes to a high voltage pulse resulted in an increase in membrane permeability to K⁺ that was dependent on both the electric field strength and the pulse duration. Exposure to a 2 μsec, 3.0 kV/cm pulse elicited a 50% loss of intracellular K⁺ indicating that the critical transmembrane potential (V_m) at breakdown was 1.26 volts …

Some Developmental Components Of The Career Decision Making Process Among College Students, Glenn Thomas Gould

Theses and Dissertations

Current research suggests that there is some relationship between developmental variables, levels of career maturity and career decisions. In this study, the relationships between certain developmental factors and the degree of certainty expressed by college students about their decision to major in a field of study were explored. The variables included the student's decision making stage, decision making styles, levels of autonomy and interpersonal relationships, and degree of career maturity. The relationships between students' status as decided or undecided about a choice of major and the variables were also investigated. The participants of this study were 104 men (n=47) and …

The Atrial Response To Ventricular And Atrial Amputation In The Adult Newt, Notophthalmus Viridescens., Timothy James Mcdonnell

Theses and Dissertations

This study describes the ultrastructure of the amphibian atrium and corroborates light microscopic evidence that atrial myocytes are stimulated to proliferate after ventricular wounding. In addition, the atrial response to a direct injury is described at light and electron microscopic levels.Normal atrial tissue from adult newts was processed for TEM. Fifteen days after ventricular wounding animals were injected with ('3)H-thymidine and atrial tissue was processed for TEM autoradiography. Direct atrial injury (DAI) was achieved by removal of a piece of the atrial wall. DAI animals received a ('3)H-thymidine injection at intervals of 5, 10, 15, 20 and 25 days after …

Depositional Environments And Diagenesis Of The Ratcliffe Interval, Madison Group (Mississippian), Williston Basin, North Dakota, Diane M. Catt

Theses and Dissertations

The Ratcliffe interval in North Dakota is a log marker-defined unit in the Williston Basin. It is Mississippian in age and crosscuts the lower Charles and upper Mission Canyon Formations of the Madison Group. Study of cross-sections, well core, and thinsections show that the Ratcliffe is comprised of six major facies: 1) brachiopod-bryozoan-echinoderm wackestone/packstone, 2) peloid packstone/wackestone, 3) oolite-peloid packstone, 4) laminated mudstone, 5) quartz siltstone packstone, and 6) anhydrite-dolomite mudstone. These facies were deposited in a regressive setting.

The initial deposition consisted mainly of marine limestones. The environment gradually became more restricted and deposition of large amounts of anhydrite …

Carbonate Bodies Within The Basal Swift Formation (Jurassic) Of Northwestern North Dakota, Tina M. Langtry

Theses and Dissertations

The carbonate bodies of the basal Swift Formation (Upper Jurassic) occur as anomalous deflections on a relatively uniform mechanical well log section. The areal distribution, stratigraphic relationships, and genesis of the carbonate bodies were determined by using the gamma ray log, the spontaneous-potential log, the resistivity log suite, and megascopic and microscopic core analysis.

The carbonate bodies of the basal Swift Formation are coarsening upward sequences composed of predominantly sand-sized, recrystallized mollusk grains. These grains were transported by strong bottom cur rents across the irregular sea floor of the shallow epicontinental Jurassic sea, and were deposited under agitated water conditions …

Depositional Environment And Diagenesis, Birdbear Formation (Upper Devonian) Williston Basin, North Dakota, Peter T. Loeffler

Theses and Dissertations

The Birdbear Formation is a subsurface unit that is present throughout North Dakota except where truncated by post-depositional erosion. An angular unconformity is present between the Birdbear and younger strata in areas where the Three Forks Formation does not overlie the Birdbear. An isopach map of the Birdbear, constructed from drill-hole log data, indicates that the formation generally thickens gradually from the erosional limit to a maximum of 119 feet north of the center of the Basin. A structure map o~ the top of the Birdbear shows a basin that reaches 9000 feet below sea level.

The Birdbear is predominantly …
