Application of Synthetic Peptides as Substrates for Reversible Phosphorylation

Description: Two highly homologous synthetic peptides MLC(3-13) (K-R-A-K-A-K-T-TK-K-R-G) and MLC(5-13) (A-K-A-K-T-T-K-K-R-G) corresponding to the amino terminal amino acid sequence of smooth muscle myosin light chain were utilized as substrates for protein kinase C purified from murine lymphosarcoma tumors to determine the role of the primary amino acid sequence of protein kinase C substrates in defining the lipid (phosphatidyl serine and diacylglycerol) requirements for the activation of the enzyme. Removal of the basic residues lysine and arginine from the amino terminus of MLC(3-13) did not have a significant effect on the Ka value of diacylglycerol. The binding of effector to calcium-protein kinase C appears to be random since binding of one effector did not block the binding of the other.

An Ethnographic Study of Outstanding, Veteran Elementary Teachers

Description: The purpose of this study was to describe outstanding, veteran elementary teachers using an ethnographic approach. This qualitative study was conducted in a suburban independent school district in northeast Texas serving approximately 17,000 students. The data collected focused on five outstanding, veteran elementary teachers who had at least twenty years of uninterrupted teaching service. Data were collected through interviews, classroom observations, and the administration of the Mind Styles (Gregorc,1982) inventory. The findings of this research were as follows. This study found that many factors were responsible for retaining outstanding, veteran elementary teachers in the work force. These included adequate preparation, a strong personal commitment, a successful initial teaching assignment, a development of skills and abilities inside and outside the teaching field, and professional accomplishments throughout the teaching career.

T. S. Eliot's Ash Wednesday: a Philosophical Approach to Empowering the Feminine

Description: In his 1916 dissertation, Eliot asserted that individuals were locked into finite centers and that all knowledge was epistemologically relative, but he also believed that finite centers could be transcended through language. In the essay "Lancelot Andrewes,'" Eliot identified Andrewes's "relevant intensity," a method very close to nonsensical verse. Eliot used Andrewes's Word and the impersonality of nonsense verse in Ash Wednesday. The Word, God's logos, embodied the Virgin Mary as its source, and allowed Eliot to transcend the finite center through language. Ultimately, Eliot philosophically empowered the feminine as the source of the Word. Though failing to fully empower the earthly Lady in part II of Ash Wednesday, Eliot did present a philosophical plan for transcending the finite center through language.

Alcoholism and the Family: The Destructive Forces in Hardy's Tess of the D'urbervilles

Description: This study examines the forces which shaped the main character--Tess Durbeyfield--in Hardy's novel in terms of the effects which her alcoholic family had upon her mental and emotional potential and which ultimately become the determining factors in her self-destruction. Using the elements and patterns set forth in the literature regarding the dynamics of the alcoholic family, I attempt to show that Hardy's novel may best be understood as the story of a woman whose life and destiny are controlled by the consequences of her father's alcoholism. This interpretation seems to account best for many elements of the novel, such as Tess's destruction, and provides a rich appreciation of Hardy's technique and vision.

The Rise and Fall of Military Regimes in the Sudan, 1956-1989

Description: This study attempts to explore the factors that contributed to the rise and fall of military regimes in the Sudan from independence in 1956 to 1989. Further, the study tries to identify the factors that led to the collapse of either or both civilian and military regimes. Most of the studies on military politics have focused their research on either military coups or, more recently, on military withdrawal from politics. This work tries to synthesize the study of military coups and military withdrawal from politics into a single theoretical framework.

Interpersonal Perception and Communication within Marital Dyads

Description: The present study examined the relationships among similarity, interpersonal perception and communicative behaviors in marriage. It was hypothesized that greater understanding, feelings of being understood, and realization of understanding would be associated with greater self-disclosure, use of more direct person control strategies, and use of less attention control strategies. It was further hypothesized that measuring feelings of being understood and realization of understanding, in addition to measuring understanding, would improve prediction of behavior. Finally, it was hypothesized that the contextual measure of understanding would better predict self-disclosure and interpersonal control than would global measures of understanding.

Evaluation of Diet, Water, and Culture Size for Ceriodaphnia Dubia Laboratory Culturing

Description: Six reagent waters, eleven diets, and two culture sizes were evaluated for culturing C. dubia. Different filtration techniques were used to prepare the reagent waters. The eleven diets were comprised of two algae augmented with eight supplements. Reproduction and growth were assessed to discern differences among C. dubia raised in mass cultures and cultured in individual cups, during which, bacterial population densities, lipid, protein, and carbohydrate concentrations of the diets were measured. Results showed that a glass-distilled, carbon filtered, deionized reagent water and a Selenastrum capricornutum- Cerophyl® diet were optimum for culturing. Mass culturing supported the highest reproduction and growth, while no correlation was found between nutritional measurements and production.

Aortic Baroreceptor Reflex Control of Blood Pressure: Effect of Fitness

Description: Aortic baroreflex (ABR) control of blood pressure was examined in 7 untrained (UT) and 8 endurance exercise trained (EET) young men. ABR control of blood pressure was determined during a steady state phenylephrine infusion to increase mean arterial pressure 10-15 mmHg, combined with positive neck pressure to counteract the increased carotid sinus transmural pressure, and low levels of lower body negative pressure to counteract the increased central venous pressure. Functioning alone, the ABR was functionally adequate to control blood pressure. However, ABR control of HR was significantly diminished in the EET subjects due solely to the decrease in the ABR sensitivity. The persistent strain from an increased stroke volume resulting from endurance exercise training could be the responsible mechanism.

Progressivism/prohibition and war: Texas, 1914-1918

Description: This thesis focuses upon the impact of war upon the progressive movement in Texas during 1914-1918. Chapter I defines progressivism in Texas and presents an overview of the political situation in the state as relating to the period. Chapter II discusses the negative impact that the first two years of World War I had upon the reform movement. Chapter III examines the revival of the Anti-Saloon League and the 1916 Democratic state convention. Chapter IV covers the war between James E. Ferguson and the University of Texas. Chapter V tells how the European war became a catalyst for the reform movement in Texas following America's entry, and its subsequent influence upon the election of 1918. Chapter VI concludes that James E. Ferguson's war with the University of Texas as well as World War I were responsible for the prohibitionist victory in the election of 1918.

Nucleotide Sequence Determination, Subcloning, Expression and Characterization of the xy1LT Region of the Pseudomonas putida TOL Plasmid pDK1

Description: The complete nucleotide sequence of the region encoding the DHCDH function of the pDK1 lower operon was determined. DNA analysis has shown the presence of two open reading frames, one gene consisting of 777 nucleotides encoding a polypeptide of 27.85 kDa and another gene of 303 nucleotides encoding a polypeptide of 11.13 kDa. The results of enzymatic expression studies suggest that DHCDH activity is associated only with xy1L. However although the addition of xy1T cell-free extracts to xy1L cell-free extracts does not produce an increase in DHCDH activity, subclones carrying both xy1L and xy1T exhibit 300- 400% more DHCDH activity than subclones carrying only xy1L.

The Effectiveness of an Exercise Intervention Program in Reducing Cardiovascular Risk Among Employees in a University Setting

Description: Nine physiological measures were evaluated pre- to post-intervention on subjects participating in a university health promotion program over a seven-month period. Frequency of program attendance and choice of activity were also assessed. Of the 88 employees initially screened, most of the subjects were staff members (n=82, 93%),with a majority being female (n=68, 77%). Significant differences in physiological measures were found pre- to post-intervention between "higher" and "lower" cardiovascular risk participants, primarily due to the type of activity chosen. .The results indicate that health promotion programs at a university are an effective way to have an impact on employees in reducing their cardiovascular risk factors.
