Solvation!
This dissertation consists of two closely related parts: theory development and coding of correlation effects in a model potential for solvation, and study of solvent effects on chemical reactions and processes. The effective fragment potential (EFP) method has been re-parameterized, using density functional theory (DFT), more specifically, the B3LYP functional. The DFT based EFP method includes short-range correlation effects; hence it is a first step in incorporating the treatment of correlation in the EFP solvation model. In addition, the gradient of the charge penetration term in the EFP model was derived and coded. The new method has been implemented in the electronic structure code GAMESS and is in use. Formulas for the dynamic dipole polarizability, C{sub 6} dispersion coefficient and dispersion energy were derived and coded as a part of a treatment of the dispersion interactions in the general solvation model, EFP2. Preliminary results are in good agreement with experimental and other theoretical data. The DFT based EFP (EFP1/DFT) method was used in the study of microsolvation effects on the S{sub N}2 substitution reaction, between chloride and methyl bromide. Changes in the central barrier, for several lowest lying isomers of the systems with one, two, three and four waters, were …

Question of Honor
My thesis, Question of Honor, addresses the premise of women's lack of choice in relation to men's honor, and vengeance; concepts that are closely connected to the oppressive world of women in Pakistan. These works deal with concepts of purity and minor transgressions that have an impact on the lives of women in relation to family names and the associative feelings of humiliation linked to men. The subtle nuances of women and their reactions to oppression give a strong emotive content to the work.

Pseudoscalar Semileptonic Decays of the D0 Meson
The FOCUS experiment is designed to investigate charm particle decays. These charm particles are produced by the interaction of a photon beam with an average energy of 175 GeV on a BeO target and travel an average of few millimeters before decaying in the spectrometer. By reconstructing the daughters from the decay, we can infer properties of the charm particles. Semileptonic decays have been used to measure many CKM matrix elements. These decays are interesting due to the simplicity of their theoretical description but they are experimentally challenging due to the fact that a neutrino is not detected. Analysis of semileptonic decays in the charm sector are of great interest because they provide an excellent environment to test and to calibrate theoretical calculation that can be implemented in the determination of poorly known matrix elements such as V{sub ub}. In this thesis we report an analysis of the decays D{sup 0} {yields} {pi}{sup -}{mu}{sup +}{nu} and D{sup 0} {yields} K{sup -} {mu}{sup +}{nu}. We measure the relative branching ratio as well as the ratio of the form factors f{sub +}{sup {pi}}(0)/f{sub +}{sup K}(0). Using a weighting technique, we further report a parametric analysis of the q{sup 2} dependence for both …

The Effect of Individual Versus Collective Creative Problem Solving Experiences on Fourth- and Fifth-grade Students' Compositional Products.
The purpose of the study was to explore the effects that individual vs. collective structured creative musical problem solving tasks had on students' compositional products. Subjects in a convenience sample of 32 fourth-graders and 32 fifth-graders were randomly assigned to either the individual or collective condition. The 3 treatment sessions were characterized by an open-ended creative problem solving task, which included questions intended to guide subjects through 3 stages of the creative problem solving process: Understanding the Problem, Generating Ideas, and Planning for Action. Subjects participated in the pre- and posttest individually. Three experienced music educators assessed the compositional products in terms of pattern use, cohesiveness, and creativity. The originally intended MANCOVAs could not be carried out because the data did not meet the necessary assumptions. Pretest and posttest scores were explored with individual ANOVAs. The Bonferroni technique was used to adjust the alpha level. The statistical analyses showed that subjects exposed to the individual condition obtained higher scores than subjects exposed to the collective condition on six of the eight explored subtests, but these differences were not significant. The level of interjudge reliability decreased at each of the three measurements of the study: pilot test, pretest, and posttest. The …

Baeyer-Villiger oxidation of 1,9-dibromopentacyclo[5.4.0.02,6.03,10.05,9]undecane-8,11-dione (1,9-dibromo-PCU-8,11-dione) was performed by using an excess amount of m-chloroperbenzoic acid (3 equivalents) and resulted in the formation of the corresponding monolactone. The reaction would not proceed to the dilactone stage. The structure of the reaction product was established unequivocally via single crystal X-ray diffraction. Baeyer-Villiger oxidation of 1,9-dibromo-PCU-8,11-dione using ceric ammonium nitrate (CAN) was also performed and afforded a mixture of lactones. Only one of these lactones, which also contained an alkene functionality, could be isolated and characterized. 1,7-dibromo-PCU-8,11-dione was also reacted with CAN, yielding the mono-lactone, which has also been characterized.

Ion Acceleration from the Interaction of Ultra-Intense Lasers with Solid Foils
The discovery that ultra-intense laser pulses (I > 10{sup 18} W/cm{sup 2}) can produce short pulse, high energy proton beams has renewed interest in the fundamental mechanisms that govern particle acceleration from laser-solid interactions. Experiments have shown that protons present as hydrocarbon contaminants on laser targets can be accelerated up to energies > 50 MeV. Different theoretical models that explain the observed results have been proposed. One model describes a front-surface acceleration mechanism based on the ponderomotive potential of the laser pulse. At high intensities (I > 10{sup 18} W/cm{sup 2}), the quiver energy of an electron oscillating in the electric field of the laser pulse exceeds the electron rest mass, requiring the consideration of relativistic effects. The relativistically correct ponderomotive potential is given by U{sub p} = ([1 + I{lambda}{sup 2}/1.3 x 10{sup 18}]{sup 1/2} - 1) m{sub o}c{sup 2}, where I{lambda}{sup 2} is the irradiance in W {micro}m{sup 2}/cm{sup 2} and m{sub o}c{sup 2} is the electron rest mass. At laser irradiance of I{lambda}{sup 2} {approx} 10{sup 20} W {micro}m{sup 2}/cm{sup 2}, the ponderomotive potential can be of order several MeV. A few recent experiments--discussed in Chapter 3 of this thesis--consider this ponderomotive potential sufficiently strong to accelerate …

From inside the Arab family: What literacy practices occur when raising bilingual and biliterate children?
Living in the United States creates unique challenges in biliteracy and bilingualism for the Arab family. While extant literature provides insight into the literacy interactions and experiences of families from many other cultures now living in the U.S. , there is next to nothing regarding the Arab family literacy experience. Thus, knowledge about the literacy activities Arab families engage in as they gain access to and knowledge of a new culture and language is important. The purpose of this study was to investigate and describe the literacy practices of the Arab families raising bilingual and biliterate children in the U.S. This study , using methodology based on ethnographic approaches, investigated the literacy events, behaviors and interactions which occurred within one Arab family over a 16-week period. A second group of participants were 5 other Arab families living in the U.S. Data sources included video and audio recordings, field notes, observations, journals, informal interviews, and artifacts of children's literacy. The researcher and the participants engaged as co-participants in the research. Findings showed that driving factors behind home literacy practices were religious beliefs and the imminence of return to the home country. Arab mothers were found to yield a heavy influence on …

Electromagnetic and mechanical design of gridded radio-frequency cavity windows
Electromagnetic, thermal and structural analyses of radio-frequency (RF) cavities were performed as part of a developmental RF cavity program for muon cooling. RF cavities are necessary to provide longitudinal focusing of the muons and to compensate for their energy loss. Closing the cavity ends by electrically conducting windows reduces the power requirement and increases the on-axis electric field for a given maximum surface electric field. Many factors must be considered in the design of RF cavity windows. RF heating can cause the windows to deform in the axial direction of the cavity. The resulting thermal stresses in the window must be maintained below the yield stress of the window material. The out-of-plane deflection must be small enough so that the consequent frequency shift is tolerable. For example, for an 805 MHz cavity, the out-of-plane deflection must be kept below 25 microns to prevent the frequency of the cavity from shifting more than 10 kHz. In addition, the window design should yield smooth electric and magnetic fields, terminate field leakage beyond the window, and minimize beam scattering. In the present thesis, gridded-tube window designs were considered because of their high structural integrity. As a starting point in the analysis, a cylindrical …

Perceptions and attributions of child, spousal, and elder abuse.
Although researchers have studied perceptions regarding sexually abused children, little was known about how other types of abusive events were perceived. This study examined 480 college students' abuse history and perceptions of child, spousal, and elder abuse by varying the respondent, victim, and perpetrator genders. Physical abuse, psychological abuse, and neglect were investigated. Perceptions of abusiveness, seriousness, harm, and responsibility were examined, along with the extent of identification with the victims/perpetrators. Participants viewed spousal abuse as less serious and harmful than other abuse types, especially when perpetrated against a male or by a female. Although able to recognize psychological abuse, students did not fully understand what other abuse types entailed. Individuals also showed a considerable amount of blame toward victims. Results further demonstrated important findings about how ethnic identity/orientation, religious affiliation, and history of abuse related to perceptions of abusive events.

Nitric Acid Dehydration Using Perfluoro Carboxylate and Mixed Sulfonate/Carboxylate Membranes
Perfluoro ionomer membranes are tetrafluoro ethylene-based materials with microheterogeneous structures consisting of a hydrophobic polymer backbone and a hydrophilic side-chain cluster region. Due to the ionomer cluster morphology, these films exhibit unique transport properties. Recent investigations with perfluoro sulfonate and perfluoro sulfonate/carboxylate composite polymers have demonstrated their value in the dehydration of nitric acid and they show potential as an alternative to conventional, energy intensive unit operations in the concentration of acid feeds. As a result, investigations were conducted to determine the feasibility of using pure perfluoro carboxylate and mixed perfluoro sulfonate/carboxylate films for the dehydration of nitric acid because of the speculation of improved water selectivity of the carboxylate pendant chain. During the first phase of these investigations the effort was focused on generating a thin, solution cast perfluoro carboxylate ionomer film, to evaluate the general, chemical and physical characteristics of the polymer, and to assess the material's aqueous transport performance (flux and nitrate separation efficiencies) in pervaporation and high-pressure environments. Results demonstrated that generating robust solution-cast films was difficult yet a number of membranes survived high trans-membrane pressures up to 700 psig. General characterization of the solution cast product showed reduced ion exchange capacities when compared with thicker, …

Evaluation of virulence in wild type and pyrimidine auxotrophs of Pseudomonas aeruginosa using the eukaryotic model system Caenorhabditis elegans.
Access:
Use of this item is restricted to the UNT Community
The human opportunistic pathogen, Pseudomonas aeruginosa PAO1, has been shown to kill the nematode Caenorhabditis elegans. C. elegans has been a valuable model for the study of bacterial pathogenesis, and has reinforced the notion that common virulence and host defense mechanisms exist. Recently, the pyrimidine pathway was shown to regulate virulence levels. Therefore, mutations in the pyrimidine pathway of PAO1 showed decrease virulence in the nematode. When starving the nematode, bacterial resistance was also shown to increase. It was hypothesized that starvation induced the DAF pathway, which regulates the transcription of genes involved with the antibacterial defense mechanism. Further research will be conducted to test this theory by performing RNAi experiments for the genes functioning in the antibacterial defense mechanism.

Non-Poissonian statistics, aging and "blinking'" quantum dots.
This dissertation addresses the delicate problem of aging in complex systems characterized by non-Poissonian statistics. With reference to a generic two-states system interacting with a bath it is shown that to properly describe the evolution of such a system within the formalism of the continuous time random walk (CTRW), it has to be taken into account that, if the system is prepared at time t=0 and the observation of the system starts at a later time ta>0, the distribution of the first sojourn times in each of the two states depends on ta, the age of the system. It is shown that this aging property in the fractional derivative formalism forces to introduce a fractional index depending on time. It is shown also that, when a stationary condition exists, the Onsager regression principle is fulfilled only if the system is aged and consequently if an infinitely aged distribution for the first sojourn times is adopted in the CTRW formalism used to describe the system itself. This dissertation, as final result, shows how to extend to the non-Poisson case the Kubo Anderson (KA) lineshape theory, so as to turn it into a theoretical tool adequate to describe the time evolution of …

An Analysis of Adler's Theory and the Female Criminal
This research paper addressed the following question: Do select case studies conform to Dr. Freda Adler's theory regarding socio-economic influences on female criminal behavior or dispute her theory? My research involved three female criminals: Karla Faye Tucker, Andrea Yates, and Susan Smith. I addressed Adler's theory in detail, other theories, the makeup of the female criminal and various female crimes. This study provided evidence that all three case studies conform to Adler's theory. nIn accordance with Adler's theory, each of these three females committed crimes of accessibility. None of the three individuals sought to commit a premeditated act or to murder unknown victims. They were motivated by emotions arising at a point in time when access/opportunity presented itself.

The Anatomy of Academic Dishonesty: Cognitive Development, Self-Concept, Neutralization Techniques, and Attitudes Toward Cheating
This study explored the relationship between cheating among university students and their cognitive developmental levels, use of neutralization techniques, self-concept as a multifaceted cognitive construct, and attitude toward cheating. The purposes of this study were to investigate: (1) The relationships between academic dishonesty and each of the following overall independent variables: cognitive development, use of neutralization techniques, self-concept as a multifaceted cognitive construct, and attitude toward cheating, and (2) the reasons behind college student academic cheating behaviors. The study used data from anonymous, self-report surveys administered to undergraduate students in-class and at supplemental sessions. Student participation was voluntary. The study was correlational. The five hypotheses were: (1) Self-concept is significantly and negatively related to academic dishonesty; (2) Cognitive development is significantly and negatively related to academic dishonesty; (3) Attitude toward cheating is significantly and negatively related to academic dishonesty; (4) The use of neutralization techniques is significantly and positively related to academic dishonesty; (5) Cognitive development, self-concept, and attitude toward cheating will make significant contributions to the regression model for the dependent variables of academic dishonesty. The data supported the first, third, and fourth hypotheses. However, the second and fifth hypotheses were supported under certain conditions. The roles of cognitive …

Soft X-ray emission spectroscopy of liquids and lithium batterymaterials
Lithium ion insertion into electrode materials is commonly used in rechargeable battery technology. The insertion implies changes in both the crystal structure and the electronic structure of the electrode material. Side-reactions may occur on the surface of the electrode which is exposed to the electrolyte and form a solid electrolyte interface (SEI). The understanding of these processes is of great importance for improving battery performance. The chemical and physical properties of water and alcohols are complicated by the presence of strong hydrogen bonding. Various experimental techniques have been used to study geometrical structures and different models have been proposed to view the details of how these liquids are geometrically organized by hydrogen bonding. However, very little is known about the electronic structure of these liquids, mainly due to the lack of suitable experimental tools. In this thesis examples of studies of lithium battery electrodes and liquid systems using soft x-ray emission spectroscopy will be presented. Monochromatized synchrotron radiation has been used to accomplish selective excitation, in terms of energy and polarization. The electronic structure of graphite electrodes has been studied, before and after lithium intercalation. Changes in the electronic structure upon lithiation due to transfer of electrons into the graphite …

Aspects of the SrO-CuO-TiO2 Ternary System Related to the Deposition of SrTiO3 and Copper-Doped SrTiO3 Thin-Film Buffer Layers
YBa{sub 2}Cu{sub 3}O{sub 7-{delta}} (YBCO) coated conductors are promising materials for large-scale superconductivity applications. One version of a YBCO coated conductor is based on ion beam assisted deposition (IBAD) of magnesium oxide (MgO) onto polycrystalline metal substrates. SrTiO{sub 3} (STO) is often deposited by physical vapor deposition (PVD) methods as a buffer layer between the YBCO and IBAD MgO due to its chemical stability and lattice mismatch of only {approx}1.5% with YBCO. In this work, some aspects of the stability of STO with respect to copper (Cu) and chemical solution deposition of STO on IBAD MgO templates were examined. Solubility limits of Cu in STO were established by processing Cu-doped STO powders by conventional bulk preparation techniques. The maximum solubility of Cu in STO was {approx}1% as determined by transmission electron microscopy (TEM) and Rietveld refinements of x-ray diffraction (XRD) data. XRD analysis, performed in collaboration with NIST, on powder compositions on the STO/SrCuO{sub 2} tie line did not identify any ternary phases. SrCu{sub 0.10}Ti{sub 0.90}O{sub y} buffer layers were prepared by pulsed laser deposition (PLD) and CSD on IBAD MgO flexible metallic textured tapes.

Gas Sensors Based on Ceramic p-n Heterocontacts
Ceramic p-n heterocontacts based on CuO/ZnO were successfully synthesized and a systematic study of their hydrogen sensitivity was conducted. The sensitivity and response rates of CuO/ZnO sensors were studied utilizing current-voltage, current-time, and impedance spectroscopy measurements. The heterocontacts showed well-defined rectifying characteristics and were observed to detect hydrogen via both dc and ac measurements. Surface coverage data were derived from current-time measurements which were then fit to a two-site Langmuir adsorption model quite satisfactorily. The fit suggested that there should be two energetically different adsorption sites in the system. The heterocontacts were doped in an attempt to increase the sensitivity and the response rate of the sensor. First, the effects of doping the p-type (CuO) on the sensor characteristics were investigated. Doping the p-type CuO with both acceptor and isovalent dopants greatly improved the hydrogen sensitivity. The sensitivity of pure heterocontact observed via I-V measurements was increased from {approx}2.3 to {approx}9.4 with Ni doping. Dopants also enhanced the rectifying characteristics of the heterocontacts. Small amounts of Li addition were shown to decrease the reverse bias (saturation) current to 0.2 mA at a bias level of -5V. No unambiguous trends were observed between the sensitivity, the conductivity, and the density of …

A Measurement of the production cross section of top-antitop pairs in proton-antiproton collisions at a center of mass of 1.96 TeV using secondary vertex b-tagging.
A measurement of the t{bar t} pair production cross section is presented using 162 pb{sup -1} of data collected by the CDF experiment during Run II at the Tevatron. t{bar t} events in the lepton+jets channel are isolated by identifying electrons and muons, reconstructing jets and transverse missing energy, and identifying b jets with a secondary vertex tagging algorithm. The efficiency of the algorithm is measured in a control sample using a novel technique that is less dependent on the simulation. For a top quark mass of 175 GeV/c{sup 2}, a cross section of {sigma}{sub t{bar t}} = 5.6{sub -1.1}{sup +1.2}(stat.){sub -0.6}{sup +0.9}(syst.)pb is measured.

Dallas as Region: Mark Lemmon's Gothic Revival Highland Park Presbyterian Church
Informed by the methodology utilized in Peter Williams's Houses of God: Region, Religion, and Architecture in the United States (1997), the thesis examines Mark Lemmon's Gothic Revival design for the Highland Park Presbyterian Church (1941) with special attention to the denomination and social class of the congregation and the architectural style of the church. Beginning with the notion that Lemmon's church is more complex than an expression of the Southern cultural region defined by Williams, the thesis presents the opportunity to examine the church in the context of the unique cultural region of the city of Dallas. Church archival material supports the argument that the congregation deliberately sought to identify with both the forms and ideology of the late nineteenth-century Gothic Revival in the northeastern United States, a result of the influence of Dallas's cultural region.

The Snare Drum as a Solo Concert Instrument: An In-Depth Study of Works by Milton Babbitt, John Cage, Dan Senn, and Stuart Saunders Smith, Together with Three Recitals of Selected Works by Keiko Abe, Daniel Levitan, Askell Masson, Karlheinz Stockhausen, and Others
This dissertation discusses the potential of the snare drum as a solo concert instrument. Four pieces from a collection entitled The Noble Snare are used for demonstration ("Homily" by Milton Babbitt, "Composed Improvisation for Snare Drum" by John Cage, "Peeping Tom" by Dan Senn, and "The Noble Snare" by Stuart Saunders Smith). In the absence of many traditional musical devices (i.e. melody and harmony), alternative means of expression are used by the composer. Each piece is discussed with regard to its distinctive compositional approach and inherent performance issues. Information is also given pertaining to the background of the Noble Snare series. This includes: the inspiration for the project, editorial issues, and its influence on snare drum performance. Much of this research was completed through interviews by with author with Sylvia Smith, publisher of The Noble Snare and owner of Smith Publications.
