Boffin's Books And Darwin's Finches: Victorian Cultures Of Collecting, Michael W. Hancock '89 Dec 2006

Boffin's Books And Darwin's Finches: Victorian Cultures Of Collecting, Michael W. Hancock '89

Doctoral Dissertations

Although wealthy continental virtuosos had passionately and selectively accumulated a variety of natural and artificial objects from the Renaissance onwards, not until the nineteenth century did collecting become a conspicuous national pastime among all classes in Britain. As industry and empire made available many new and exotic goods for acquisition and display, the collection as a cultural form offered the Victorians a popular strategy of self-fashioning that was often represented in the literature of the age as a source of prestige and social legitimation. Through interdisciplinary readings of Victorian fiction, narrative nonfiction, and poetry, my study examines how textual representations ...

Instructional Leadership And Academic Performance In Tennessee High Schools, Denise Minton Johnson Dec 2006

Instructional Leadership And Academic Performance In Tennessee High Schools, Denise Minton Johnson

Doctoral Dissertations

During this era of high academic accountability, principals are expected to be learning leaders and to orchestrate their schools' academic improvement. Despite these high expectations, few studies have linked principal instructional leadership behavior with student academic achievement. The purpose of this study was to determine if differences in instructional leadership behavior existed between principals of high-achieving, high-performing, low-achieving, and low-performing schools.

The population of this study was public high school principals in Tennessee. Two hundred seventy-six (276) principals whose schools' State of Tennessee Report Cards contained three years of academic achievement and academic performance data were surveyed using the Principal ...

Hydrodynamic Wave Contributions To Combustion Instability In Rockets, Esam M. T. Abu-Irshaid Dec 2006

Hydrodynamic Wave Contributions To Combustion Instability In Rockets, Esam M. T. Abu-Irshaid

Doctoral Dissertations

Experimental measurements suggest that a new source of instability in rocket motors is due to hydrodynamic disturbances. These disturbances, if ignored, could impact our assessment of rocket motor performance. In this work, the corresponding problem of hydrodynamic instability is considered. A mathematical model for these disturbances is carried out by perturbing the continuity and momentum equations. A one dimensional model which represents the wave disturbances in time and space is implemented to quantify the amplification rate, in time or space, and the wave amplitude. The only available measurements of these disturbances arise in cold flow experiments that simulate the gas ...


The Effects Of Fast Secondary Electrons On Low Voltage Electron Beam Lithography, Mehdi Bolorizadeh Dec 2006

The Effects Of Fast Secondary Electrons On Low Voltage Electron Beam Lithography, Mehdi Bolorizadeh

Doctoral Dissertations

In 1981 Prof. Sir Alec Broers suggested that the spatial limit of direct writing electron beam lithography (DWEBL) would be limited to ~10 nm by the laterally scattered fast secondary electrons (FSE) even in atomically thin resist. Experiments and simulations have been carried out to quantify the contribution of FSE to the energy deposition that results in exposure of the resist over high beam energies. One possible solution to this restriction would be to use low energy electrons.

To examine Broers' hypothesis in low voltage electron beam lithography (EBL), studies in the low energy range on the effects of FSE ...


Weaving The Threads Of Relational Connectedness Between Women: Exploring How Women Make Meaning In Their Lives Through Relationships With Other Women, Lee Ann Alley Jolley Dec 2006

Weaving The Threads Of Relational Connectedness Between Women: Exploring How Women Make Meaning In Their Lives Through Relationships With Other Women, Lee Ann Alley Jolley

Doctoral Dissertations

The dearth of research on women's female friendships might suggest that a woman's relationships with her girlfriends are less important than her relationships with her partner, children, or parents. Few researchers have focused on the closeness of female friendships despite the fact that those studies that have been conducted have found those friendships to be significant, and over the course of a woman's life, of great importance to her growth and development.

This study took a phenomenological approach in order to understand the lived experiences of women regarding their female friendships, focusing on how women make meaning ...


Not So Immaculately Conceived: Imagining The Protestant Madonna 1850-1910, Deborah Ann Scaperoth Dec 2006

Not So Immaculately Conceived: Imagining The Protestant Madonna 1850-1910, Deborah Ann Scaperoth

Doctoral Dissertations

Pius IX in the 1854 Bull Ineffabilis Deus defined the dogma of the Immaculate Conception as the belief that Mary; mother of Jesus, was from the moment of her conception free from the "stain of original sin." This idea was a part of ecclesiastical tradition, but prior to this time, the church had not officially defined Mary's sinless nature in writing. The publication of this definition, along with published accounts of Marian sightings, contributed to an already heightened awareness of her in a literate, culturally aware public. As a result, Protestant writers who sought to invoke her image interpreted ...


An Investigation Of Automaticity In Learning Disabled (Ld) And Non-Clinical Adults, Kerry Towler Dec 2006

An Investigation Of Automaticity In Learning Disabled (Ld) And Non-Clinical Adults, Kerry Towler

Doctoral Dissertations

Dyslexia research has implicated phonetic dysfunction in the phoneme-grapheme associations which underlie reading skills. Expert readers of normal developmental etiology have required less mental effort, faster processing speed, and reduced focal attention when applying reading subskills. Readers with dysphonia and poorly automatized reading subskills have required more time, mental effort, and attention. Dyslexia automaticity deficit has been attributed to left hemisphere neuro-cortical disruptions of the underlying neurological substrata that support developmental acquisition of reading subskills. Effects of inefficiently automatized phoneme-grapheme skills accumulate over time resulting in poor reading skills that are detrimental to academic achievement.

Using neuropsychological methodology, adults with ...

Cross-Species Comparison Of Spermatocyte Responses To Induced Dna Damage: The Laboratory Mouse And Drosophila Melanogaster, Shannon Marie Matulis Dec 2006

Cross-Species Comparison Of Spermatocyte Responses To Induced Dna Damage: The Laboratory Mouse And Drosophila Melanogaster, Shannon Marie Matulis

Doctoral Dissertations

Maintenance of genomic stability is of crucial importance for all organisms. Cells are continually exposed to exogenous and endogenous agents that can damage DNA. Of special interest is the manner in which male germ cells respond to and repair induced DNA double strand breaks (DSBs), as the propagation of cells carrying damaged DNA can lead to the production of heritable mutations, genetic diseases, and sterility. In addition, treatment of male germ cells with DNA damaging agents, such as many chemotherapeutic drugs, can ultimately result in infertility. This research focused on investigating the mechanisms by which male germ cells, specifically those ...


The Effect Of Mobile Phase Composition And Temperature On The Adsorption Behavior Of Tryptophan, Tarab Jamil Ahmad Dec 2006

The Effect Of Mobile Phase Composition And Temperature On The Adsorption Behavior Of Tryptophan, Tarab Jamil Ahmad

Doctoral Dissertations

Single-component adsorption isotherm data were acquired by frontal analysis for tryptophan on a C18-Kromasil packed column, using acetonitrile-water solutions of various compositions (2.5, 5, and 7.5% ACN + 1% ACOH). These isotherms have a complex behavior, exhibiting at least one clear inflection point at an intermediate concentration and, possibly, another such point, close to the origin. The isotherm for 2.5 % ACN has the strongest curvature. At high concentrations, all these isotherms tend toward a limit, showing that the adsorbent has a finite saturation capacity. At low concentrations, these isotherms seem to exhibit langmuirian behavior. The isotherm ...

The branch of analytical chemistry known as separations has continued to grow and expand ever since its beginnings a century ago. With all the technological advances occurring to make separations a more powerful technique, the main goal continues to be the desired separation of the compounds of interest in a mixture. Although a desired separation may be achieved, there can always be room for improvement with regards to the time necessary for the separation as well as better resolution of closely-related species as well as enantiomers of the same analyte.

In this work, a variety of separation methods and variations ...


Measurement Of The 32S(P,D)31S Reaction And Its Astrophysical Implications, Zhanwen Ma Dec 2006

Measurement Of The 32S(P,D)31S Reaction And Its Astrophysical Implications, Zhanwen Ma

Doctoral Dissertations

The 30P(p,γ)31S reaction plays a crucial role in the synthesis of heavier nuclear species, from Si to Ca, in nova outbursts on ONe White Dwarfs [26, 28, 35]. However, its rate is very uncertain as a result of the lack of spectroscopic information on the levels above proton threshold in 31S. The currently adopted rate of this reaction, based on statistical Hauser-Feshbach calculations [36], could have an uncertainty as much as a factor of 100 higher or lower under nova conditions [26].

To reduce these uncertainties, we have measured differential cross sections for the ...


Characterization Of Aβ Aggregates Using Hydrogen/Deuterium Exchange Mass Spectrometry, Maolian Chen Dec 2006

Characterization Of Aβ Aggregates Using Hydrogen/Deuterium Exchange Mass Spectrometry, Maolian Chen

Doctoral Dissertations

The work presented in this dissertation aimed to localize the hydrogen-bonding interaction sites within Aβ aggregates associated with Alzheimer’s disease using hydrogen/deuterium exchange mass spectrometry (HDX-MS) coupled with proteolysis. Toward this end, an on-line digestion system utilizing a triaxial electrospray probe as the front end to MS was developed. Using this approach, regions of Aβ(1-40) fibrils and protofibrils that are protected from HDX have been identified. The HDX data show that the C-terminal segment 35-40 and the N-terminal segment 1-19 are highly exposed to exchange in both fibrils and protofibrils, while the internal fragment 20-34 is highly ...


Studies Of The Mechanism Of Electron Beam Induced Deposition (Ebid), Young Ryong Choi Dec 2006

Studies Of The Mechanism Of Electron Beam Induced Deposition (Ebid), Young Ryong Choi

Doctoral Dissertations

The controlled deposition of metals resulting from the passage of an ion beam through an atmosphere of a suitable precursor gas is a well-established procedure for micro scale materials manipulation. While the ion beam technique is rapid and reliable it has the disadvantage that the beam itself can ablate and contaminate the target with Gallium or other materials, and the fact that ion optics are less widely accessible than electron optical columns. We have therefore been investigating the theory and practice of depositing metal using an electron beam and variety of precursor gases. The aim of this work is to ...
