The Problem of Spelling Reform

Description: Spelling is a tool by which one records his thoughts and ideas; therefore it is a vital part of life. To fulfill its task successfully, spelling must be accurate. Spelling is that tool by which the happenings of the past are revealed to the present and are preserved for the future. For any individual who attempts to transfer his thoughts and words by symbols onto paper, correct spelling is a prime essential. It follows, then, that to develop perfect habits of spelling in order that perfect tran… more

A Study of Lean Body Mass in Estimating Basal Metabolic Rate

Description: The primary purpose of the study was to determine if measured LBM could be used as a more powerful predictor of BMR than could surface area (SA) as calculated by the formula of DuBois and DuBois (1916). It was also of interest to develop a prediction equation for BMR using multiple regression analysis. Data from 82 women and 76 men were included in the study. Pearson product-moment correlations indicated that LBM was a better predictor for BMR than SA on either of the principal SA prediction eq… more

Topical, Conceptual, and Theoretical Diversity in American Sociological Sovietology

Description: Sociology has remained for years on the fringe of Sovietological pursuits, both quantitatively and qualitatively. Yet, few have made a serious effort to systematically examine sociological Sovietology. To partially compensate for such neglect, this study begins to explore the diversity of what sociology has studied and how it has gone about studying it. Of the fourteen topic areas pursued, only four inspired disagreement and variation. Most sociology has studied the Soviet Union non-comparative… more

Dostoyevsky's American Reputation to 1930

Description: Undoubtedly, Dostoyevsky's influence upon the novel is great, but, even yet, few concrete studies have been made and no full-length study has been published. It is hoped that this account of Dostoyevsky's reputation in America during the 1920's will be of assistance in the greater task of tracing Dostoyevsky's influence.

The Student Nonviolent Coordinating Committee and Racial Dynamics: The Importance of SNCC's Arkansas Project, 1962-1966

Description: In this thesis I look at the Arkansas Project and more specifically the racial dynamics within the project and the surrounding communities in Arkansas where SNCC engaged to assist the residents fight for their civil rights. In addition, I analyze how the differences in the urban and rural communities were affected by the racial dynamics of the project's leadership. The Arkansas project was led by William Hansen, a white man, which made him and the project unique from not only other SNCC project… more

A Method of Analyzing Linear Perspective for Presentation to Junior and Senior High School Students

Description: The general purpose of this study is to develop a series of peep shows, or visual models, which will enable the young student to understand what the laws of perspective are, how they were found, and why his drawings will appear to have three dimensions if he follows the rules. The study is based upon a widely accepted idea--that it is much easier for most people to understand and remember a principle when they can actually see how it works. When rules are merely memorized, one is not assisted b… more

Glucose and Altered Ceramide Biosynthesis Impact the Transcriptome and the Lipidome of Caenorhabditis elegans

Description: The worldwide rise of diabetes and obesity has spurred research investigating the molecular mechanisms that mediate the deleterious effects associated with these diseases. Individuals with diabetes and/or obesity are at increased risk from a variety of health consequences, including heart attack, stroke and peripheral vascular disease; all of these complications have oxygen deprivation as the central component of their pathology. The nematode Caenorhabditis elegans has been established as a mod… more

An Evaluation of the Firo-B Scale with Hospitalized Psychiatric Patients

Description: Concerning the present study, if in the test result of psychotic patients there is some distortion of reality concepts, as is generally expected, then their scores on any personality scale should vary considerably from norms established on the same test by "normal" subjects.

The Use of Instructive Feedback to Promote Emergent Verbal Responses: A Replication

Description: Previous research has incorporated instructive feedback (IF) within mastered listener-by-name trials with two children diagnosed with autism spectrum disorder (ASD). Participants in a previous study acquired the secondary targets and also demonstrated emergent responding (i.e., listener-by-feature, tact-by-feature, intraverbal, and reverse intraverbal). The current study replicated a previous study on IF with two children with ASD. Therapists conducted a series of three sessions of mastered lis… more

Deposition and Characterization of Thin Metal Oxide Heterostructures for Electronic and Magnetic Device Applications

Description: The first study investigated the deposition and characterization of the CoO and Co3O4 phases of cobalt oxide. It was determined that both phases can be easily distinguishable by XPS, LEED and EELS and grown by only altering the oxygen partial pressure during MBE deposition. This fundamental knowledge gives a foundation for further experiments involving graphene growth on cobalt oxides. The second study focused on the layer-by-layer growth of graphene on another metal oxide, MgO. Past research g… more

Kinetics and Mechanisms of Metal Carbonyls

Description: Pulsed laser flash photolysis with both visible and infrared detection has been applied to the study of the displacement of weakly coordinating ligands (Lw) by strongly "trapping" nucleophiles (Ls) containing either an olefinic functionality (Ls = 1-hexene, 1-decene, 1-tetradecene) or nitrogen (Ls = acetonitrile, hydrocinnamonitrile) from the photogenerated 16 electron pentacarbonylchromium (0) intermediate. 5-Chloropent-l-ene (Cl-ol), a potentially bidentate ligand, has been shown to form (ol-… more

Metabolic Engineering in Plants to Control Source/sink Relationship and Biomass Distribution

Description: Traditional methods like pruning and breeding have historically been used in crop production to divert photoassimilates to harvested organs, but molecular biotechnology is now poised to significantly increase yield by manipulating resource partitioning. It was hypothesized that metabolic engineering in targeted sink tissues can favor resource partitioning to increase harvest. Raffinose Family Oligosaccharides (RFOs) are naturally occurring oligosaccharides that are widespread in plants and are … more

The Organizational Socialization of a Dynamic Workforce: A Focus on Employee and Contract Worker Knowledge Transfer

Description: Within the last decade, more organizations are utilizing a non-traditional workforce. Specifically, these organizations are utilizing contract workers as resources to provide services and manufacture products. While this change in workforce provides benefits to organizations, the change also presents numerous challenges such as turnover. The turnover involved in such a relationship along with the addition of newcomers translates into an organizational socialization and knowledge transfer (KT) i… more

Fumarate Activation and Kinetic Solvent Isotope Effects as Probes of the NAD-Malic Enzyme Reaction

Description: The kinetic mechanism of activation of the NAD-malic enzyme by fumarate and the transition state structure for the oxidation malate for the NAD-malic enzyme reaction have been studied. Fumarate exerts its activating effect by decreasing the off-rate for malate from the E:Mg:malate and E:Mg:NAD:malate complexes. The activation by fumarate results in a decrease in K_imalate and an increase in V/K_malate by about 2-fold, while the maximum velocity remains constant. A discrimination exists between … more

Design and Synthesis of Novel Cage-Functionalized Crown Ethers: A New Class of Ag Complexants.

Description: Three different types of cage crown ethers have been prepared and their complexation properties with Ag(I) have been studied. Atomic absorption, fluorescence quenching, and UV absorption have been used to study the interaction between the hosts (cage crown ethers) and guests (Ag+). For the cage-annulated crown ethers that contain aromatic rings, cation-π and π-π interactions may contribute significantly to the overall complexation ability of the host system. Piperazine groups may cooperate, and… more
