Lord Byron's Interest in British Politics

Lord Byron's Interest in British Politics

Date: August 1963
Creator: Krukowski, John D.
Description: The purpose of this thesis is to examine the politics of Byron as they are related to his age. Necessarily, a part of this work will deal with ideas that are somewhat conjectural, largely because of the limitations of time and space as well as the lack of accurate information--particularly that which concerns Byron and the Whig circle.

Do American Adults Know How to Exercise for a Health Benefit?

Do American Adults Know How to Exercise for a Health Benefit?

Date: December 1998
Creator: Krzewinski-Malone, Jeanette A. (Jeanette Aileen)
Description: Approximately 950,000 Americans die annually from cardiovascular disease. Physical activity is a major risk factor for the development of CVD and a risk factor for stroke. The purpose of this research was to determine whether American adults know how to exercise to achieve health benefits and whether this knowledge is a function of demographics. Items included knowledge of exercise guidelines and knowledge of traditional and non-traditional exercise activities. This information was obtained from 22 questions that were a part of a larger national survey of 2,002 American households. Statistical analyses of this sample, indicate American adults have knowledge which varies by demographic groups. Data revealed that overall the 61+, Less than High School, African-American, Hispanic-American, and Male groups have the least amount of knowledge about exercise. These data can provide health educators with important aspects of exercise knowledge for future health promotions/interventions.

X, An Analytical Approach to John Chowning's Phoné

X, An Analytical Approach to John Chowning's Phoné

Date: May 2010
Creator: Krämer, Reiner
Description: The analysis of computer music presents new challenges to the field of music theory. This study examines the fixed media composition Phoné by John Chowning from its aesthetic perspective, compositional theory and computer sound synthesis techniques. Fast Fourier Transform analyses are used to create spectrograms. The findings from the spectrograms are juxtaposed with compositional philosophies of John Chowning, Jean-Claude Risset, Pierre Schaeffer and Arnold Schoenberg and the techniques are represented via PureData patches.

Provincial Heroism: Hunanese Audiences and Sylvester Stallone

Provincial Heroism: Hunanese Audiences and Sylvester Stallone

Date: August 2012
Creator: Kuang, Jun
Description: The thesis focuses on analyzing and discussing Hunanese audience members’ receptions of three of his films – Rocky IV (1985), Cliffhanger (1993) and The Expendables (2010) to reveal the audiences’ motivations of admiring him and his movies. The analysis is based on Hunanese male characteristics because Hunanese culture is a male centric culture. In the Rocky IV film, Hunanese fans like his manhood, nature of soldier, and determination. In the response to Cliffhanger, some audience members appreciate his manhood, family value. Some members think his character is a coward, some of them even support the bad guys. In the audience’s reception of The Expendables, audiences have different opinions for different action actors. For example, Barney Ross (Stallone) was perceived as an extraordinary military leader. The thesis is divided into six chapters, and conducted upon Stuart Hall’s Encoding & Decoding theory.

Assessing the stimulus control of observers.

Assessing the stimulus control of observers.

Date: December 2009
Creator: Kuhn, Robin Merritt
Description: The science of behavior analysis relies heavily on direct observation. Human observers are typically used to measure behavior in applied settings. Although the use of human observers is beneficial in many regards, it also presents challenges. Of primary concern is the extent to which the data generated by observers actually corresponds to the behavioral events of interest, and the implications this may have in terms of replication. This study assessed the effects that labels, definitions, and examples and non-examples of two different modalities had on observer accuracy, consistency, and agreement. Results showed that current practices in observer training may require refinement to ensure high observer accuracy, consistency, and agreement. Suggestions for how to improve the desired stimulus control of observers are provided.

Backflow: A Collection

Backflow: A Collection

Date: May 2011
Creator: Kullberg, Adam
Description: This collection consists of a critical preface and nine essays. The preface analyzes, first, how the imagination influences the personal journey of a writer, and second, the techniques authors use, mainly form, time, and space, to enact the imagination and propel the reader into an imagined narrative. The essays explore themes of loss, mental illness, the rift between the “real” and the “imagined” life, and the intangibility of memory itself. Collection includes the essays “Into the Snow,” “No Longer a Part,” “Borderland,” “Still Wounds,” “What Stays in Las Vegas,” “Remnants,” “The Root,” “Your Father,” and “The Land Lord.”

Structure-Function Studies on Aspartate Transcarbamoylase and Regulation of Pyrimidine Biosynthesis by a Positive Activator Protein, PyrR in Pseudomonas putida

Structure-Function Studies on Aspartate Transcarbamoylase and Regulation of Pyrimidine Biosynthesis by a Positive Activator Protein, PyrR in Pseudomonas putida

Access: Use of this item is restricted to the UNT Community.
Date: December 2003
Creator: Kumar, Alan P.
Description: The regulation of pyrimidine biosynthesis was studied in Pseudomonas putida. The biosynthetic and salvage pathways provide pyrimidine nucleotides for RNA, DNA, cell membrane and cell wall biosynthesis. Pyrimidine metabolism is intensely studied because many of its enzymes are targets for chemotheraphy. Four aspects of pyrimidine regulation are described in this dissertation. Chapter I compares the salvage pathways of Escherichia coli and P. putida. Surprisingly, P. putida lacks several salvage enzymes including nucleoside kinases, uridine phosphorylase and cytidine deaminase. Without a functional nucleoside kinase, it was impossible to feed exogenous uridine to P. putida. To obviate this problem, uridine kinase was transferred to P. putida from E. coli and shown to function in this heterologous host. Chapter II details the enzymology of Pseudomonas aspartate transcarbamoylase (ATCase), its allosteric regulation and how it is assembled. The E. coli ATCase is a dodecamer of two different polypeptides, encoded by pyrBI. Six regulatory (PyrI) and six catalytic (PyrB) polypeptides assemble from two preformed trimers (B3) and three preformed regulatory dimers (I2) in the conserved 2B3:3I2 molecular structure. The Pseudomonas ATCase also assembles from two different polypeptides encoded by pyrBC'. However, a PyrB polypeptide combines with a PyrC. polypeptide to form a PyrB:PyrC. protomer; six ...

Substituent Effects: A Computational Study on Stabilities of Cumulenes and Low Barrier Hydrogen Bonds

Substituent Effects: A Computational Study on Stabilities of Cumulenes and Low Barrier Hydrogen Bonds

Access: Use of this item is restricted to the UNT Community.
Date: August 2000
Creator: Kumar, Ganesh Angusamy
Description: The effect of substituents on the stabilities of cumulenes-ketenes, allenes, diazomethanes and isocyanates and related systems-alkynes, nitriles and nitrile oxides is studied using the density functional theory (B3LYP, SVWN and BP86) and ab initio (HF, MP2) calculations at the 6-31G* basis set level. Using isodesmic reactions, correlation between stabilization energies of cumulenes and substituent group electronegativities (c BE) is established and the results from DFT and MP2 methods are compared with the earlier HF calculations. Calculations revealed that the density functional methods can be used to study the effect of substituents on the stabilities of cumulenes. It is observed that the cumulenes are stabilized by electropositive substituent groups from s -electron donation and p -electron withdrawal and are destabilized by electronegative substituent groups from n-p donation. The calculated geometries of the cumulenes are compared with the available experimental data.High level ab initio and density functional theory calculations have been used to study the energetics of low-barrier hydrogen bond (LBHB) systems. Using substituted formic acid-formate anion complexes as model LBHB systems, hydrogen bond strength is correlated to the pKa mismatch between the hydrogen bond donor and the hydrogen bond acceptor. LBHB model systems are characterized by the 1H-NMR chemical shift calculations. ...
