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. Remova… more

Corporate Christians and Terrible Turks: Economics, Aesthetics, and the Representation of Empire in the Early British Travel Narrative, 1630 - 1780

Description: This dissertation examines the evolution of the early English travel narrative as it relates to the development and application of mercantilist economic practices, theories of aesthetic representation, and discourses of gender and narrative authority. I attempt to redress an imbalance in critical work on pre-colonialism and colonialism, which has tended to focus either on the Renaissance, as exemplified by the works of critics such as Stephen Greenblatt and John Gillies, or on the later eightee… more

Studies on the Mechanism of Protection by Carotenoids Against Photodynamic Killing in Curtobacterium Flaccumfaciens Pathover Poinsettiae

Description: The mechanism of protection by carotenoids against photodynamic killing in Curtobacterium flaccumfaciens pathover poinsettiae (C. poinsettiae) was studied using pigment mutants isolated by treatment with nitrosoguanidine and DNA gyrase inhibitors. Growth rates, pigment composition, pigment levels and the ultrastructure of the wild-type streptomycin resistant strain of G. poinsettiae (wt-str) and all mutants were compared. One mutant, NTG-1, lacked colored carotenoids, and another, NTG-2, was a … more

Exploratory Analysis of Social E-health Behavior

Description: Extant literature has documented well that people seek health information via the internet as patients and consumers. Much less, however, is known about interaction and creation behaviors in the development of new online health information and knowledge. More specifically, generalizable sociodemographic data on who engages in this online health behavior via social media is lacking in the sociological literature. The term “social e-health” is introduced to emphasize the difference between seekin… more

Cognitive Congruence and Interactional Behavior of Cotherapists

Description: Proponents of the use of cotherapists have stressed the importance of compatibility for effective cotherapy teams; however, the nature of compatibility has received little attention in experimental literature. This study investigated the nature of an effective cotherapy relationship through use of concepts espoused by George Kelly in his personal construct theory. Based on the results of the study, it was recommended that cotherapists be paired on the basis of their cognitive congruence. It was… more

Haves, Halves, and Have-Nots: School Libraries and Student Achievement in California

Description: This descriptive, non-experimental study examines the strength of the relationship between California school library media programs and student achievement, using data from California criterion-referenced state-wide tests, publically available school and community demographic data, and a state survey of school library programs. Results indicate a substantial discrepancy in library staffing levels from the elementary grades through the high schools. Nevertheless, statistically significant corre… more

Victorian Ideology and British Children's Literature 1830-1914

Description: This dissertation shows the ideas of Victorian England, 1850-1914, as reflected in Victorian children's literature. To establish the validity of studying children's literature as a guide to the Victorian age, it was necessary first to show that children's literature in those years reflected and promoted adult ideals. Sources used include not only works by established authors but also children's periodicals and transient writings like "penny dreadfuls." There are four background chapters: an int… more

A Study to Determine the Relationship of Versatile Behavior to Individual Demographics, Job Characteristics, Organizational Climate Performance Feedback and Job Satisfaction

Description: The behavioral characteristics of leaders have been subjects of study for centuries. The scope of these studies has grown to encompass task analysis, follower needs and situational requirements. Current leadership theories consistently recognize the need for a successful leader to adjust behavior to meet the needs of the task, followers and situation. The problem of this research is to define this ability to modify one's behavior, measure it and test its relationship to demographic and job char… more

DNA-DNA Hybridization of Methane Oxidizing Bacteria

Description: Bacteria classified in the family Methylomonadaceae must derive their carbon from one-carbon compounds. They are characterized by the possession of internal membranes of two types. Type I membranes are layered and fill the middle of the cells while type II membranes form concentric layers around the periphery of the cells. Also, there are two metabolic pathways by which the methylobacteria assimilate one-carbon compounds. Further evidence of this dichotomy was sought by DNA-DNA saturation hybri… more

Perceived Effect of the Quarter System on the Programs of Selected Middle Schools in the State of Texas

Description: The problem of this study was to analyze the effect that a legislature-mandated quarter system was having on certain selected middle schools in the State of Texas, Some educators have claimed that the quarter system makes it possible to add flexibility to school programs. This study, therefore, was an attempt to find out if local school districts were taking advantage of this opportunity. A second goal of the study was to determine how principals, teachers, and curriculum directors felt about t… more

Vibrational Spectra and Potential Function of Tetrachlorocyclopropene

Description: The laser Raman spectra of tetrachlorocyclopropene in the liquid and solid phases have been recorded and vibrational assignments are presented. These results along with root mean squared vibrational amplitudes from electron diffraction data have been employed in a normal coordinate analysis in which a 19 parameter potential function is refined. This potential function, originally expressed in terms of compliance constants, is then used to derive the corresponding conventional and relaxed force … more

Joint Schemes for Physical Layer Security and Error Correction

Description: The major challenges facing resource constraint wireless devices are error resilience, security and speed. Three joint schemes are presented in this research which could be broadly divided into error correction based and cipher based. The error correction based ciphers take advantage of the properties of LDPC codes and Nordstrom Robinson code. A cipher-based cryptosystem is also presented in this research. The complexity of this scheme is reduced compared to conventional schemes. The securities… more

VLSI Architecture and FPGA Prototyping of a Secure Digital Camera for Biometric Application

Description: This thesis presents a secure digital camera (SDC) that inserts biometric data into images found in forms of identification such as the newly proposed electronic passport. However, putting biometric data in passports makes the data vulnerable for theft, causing privacy related issues. An effective solution to combating unauthorized access such as skimming (obtaining data from the passport's owner who did not willingly submit the data) or eavesdropping (intercepting information as it moves from… more

Someone to Talk to: Conversations Between Friends in a Junior High Lunch Room

Description: Quantitative studies dominate early adolescence research, a field which also lacks an understanding of communication behaviors between early adolescents. This study uses the qualitative methods of participant observation and informal interviews to observe conversations between girls in a junior high lunch room. Friendship characteristics and group socialization are discussed as they emerged from the field data. First, friendship hierarchies (best friend, close friend, and friend) may be adult-i… more
