Relationships Between Prior Experiences, Current Teaching Contexts, And Novice Teachers' Use Of Concrete Representation For Mathematics Instruction, Elizabeth Lee Johnson Dec 2014

Relationships Between Prior Experiences, Current Teaching Contexts, And Novice Teachers' Use Of Concrete Representation For Mathematics Instruction, Elizabeth Lee Johnson

Theses and Dissertations

This case study documents the perceived influences on three novice elementary teachers’ use of concrete representations for teaching mathematics. In order to develop mathematical proficiency, students need access to a variety of representations (i.e. pictures, words, symbols, concrete materials, and real world contexts) to make sense of mathematical ideas. Three sources of data were collected: video-recorded lessons, interviews, and a focus group. Analyses indicated that although concrete representations were accessible to all three teachers, they were least used among the available representations. Verbal expression was most prominent, followed closely by abstract written symbols. Technology, which was not one of the …

A Legal Analysis Of Court Cases And Administrative Investigations Related To Violations Of The Clery Act: Getting Good From The Bad And The Ugly, Tiffany Nichole Richardson Dec 2014

A Legal Analysis Of Court Cases And Administrative Investigations Related To Violations Of The Clery Act: Getting Good From The Bad And The Ugly, Tiffany Nichole Richardson

Theses and Dissertations

College brochures paint pictures of beautiful campuses, diverse student populations, renowned professors, and the best educational programs. What colleges never include in those brochures are the ugly crime statistics. In 2012, higher education institutions reported 41,708 liquor arrests, 20,486 burglaries, 4,837 forcible sex offenses, 951 hate crimes, and 31 murders. The reporting requirement, along with other regulations, has been required of institutions of higher education since 1990 under the Jeanne Clery Disclosure of Campus Security Policy and Campus Crime Statistics Act, yet so many colleges and universities are facing lawsuits, investigations, settlements, and fines for failing to comply. This legal …

Toward The Combinatorial Development Of Hydrophobic-Tagged Antifolate-Directed Degradation Of Human Thymidylate Synthase, Daniel J. Menasco Dec 2014

Toward The Combinatorial Development Of Hydrophobic-Tagged Antifolate-Directed Degradation Of Human Thymidylate Synthase, Daniel J. Menasco

Theses and Dissertations

Direct post-translational control over a protein of interest (POI) can be exploited by manipulating the cells protein quality-control systems responsible for either intracellular turnover through ubiquitination (POI half-life) or repairing and degrading misfolded proteins.1 In an effort to target and degrade a high value POI we selected the enzyme human thymidylate synthase (TS) for post-translational degradation through ligand-directed ubiquitination and hydrophobic tagging. Thymidylate synthase catalyzes the reductive methylation of 2’-deoxyuridine monophosphate (dUMP) to 2’-deoxythymidine monophosphate (dTMP). As the de novo source of dTMP the regulation of intracellular TS is strictly controlled by ubiquitinindependent proteasomal degradation mediated by an internal TS-degron …

Grand Prix: A Trainer's Guide To Show Ring Success, Lauren Rebecca Allen

Theses and Dissertations

This is a memoir of my experiences as a horse lover and professional horse trainer, and the startling parallels I discovered in the Los Angeles equestrian and entertainment industries. Both worlds revolve around commodifying something that is rooted in beauty but somehow gets bruised in the process of spinning art into business. I found that my taste for romance and adventure spurred me to new heights and simultaneously crashed against reality. In pursuit of the big prizes, I was willing to slowly sell off the things I cared about most to get what I wanted, until I woke up to …

Determinants Of Product Upgrading In The Argentine Wine Industry, Lucas Marc Cyr Dec 2014

Determinants Of Product Upgrading In The Argentine Wine Industry, Lucas Marc Cyr

Theses and Dissertations

In this thesis, I examine the impact that a firm's connections and internal resources has on the firm's ability to develop new products. The capability to make improvements to products is crucial to the long term success and growth of a firm. By using structural equation modeling, I take a different approach to network analysis to analyze data from the Argentine wine industry. While I did not find strong evidence to support the hypothesis that the combination of external networks and internal knowledge are key drivers to product upgrading, there was strong evidence to support each individual determinant’s impact on …

Defining And Supporting Organizational Readiness In The Interactive Systems Framework For Dissemination And Implementaion, Jonathan Peter Scaccia Dec 2014

Defining And Supporting Organizational Readiness In The Interactive Systems Framework For Dissemination And Implementaion, Jonathan Peter Scaccia

Theses and Dissertations

Introduction. In the implementation literature, organizational readiness is associated with an increased likelihood of achieving innovation outcomes. Organizational readiness consists of organizational capacity (general and innovation-specific) and organization motivation. Organizations who wish to get results from their innovations have an interest in making sure that certain factors and subcomponents are in place. However, having awareness that certain capacities and factors that influence motivation are linked to improved innovation outcomes does not necessarily help organizations to get “more ready.” There is a need for organizations to know if and how they can effectively put these factors and subcomponents into place. This …

Universal Two-Electron Correlation Operator On Excited States, Bryan Thomas Nichols Dec 2014

Universal Two-Electron Correlation Operator On Excited States, Bryan Thomas Nichols

Theses and Dissertations

Excited states of chemical systems are extremely important in understanding spectra, chemical phenomena, as well as how a particular compound behaves in reactions. Computationally, excited states are normally very expensive to calculate. The difficulty in calculating these states with wavefunction based methods can be mainly attributed to the calculation of large multi-determinant wavefunctions. One reason to use a complicated multi-determinant wavefunction is to include some of the effects of correlation energy. The quantity of correlation energy can most simply be defined as the reduction in energy caused by any two or more electrons trying to avoid each other. The most …

Advanced Digital Signal Processing Based Redefined Power Quality Indices, And Their Applications To Wind Power, Md Moinul Islam Dec 2014

Advanced Digital Signal Processing Based Redefined Power Quality Indices, And Their Applications To Wind Power, Md Moinul Islam

Theses and Dissertations

This dissertation proposes a time-frequency distribution (TFD) based new method to redefine the power quality (PQ) indices for the assessment of PQ disturbances typically present in electric power systems. The redefined PQ indices are applied to various types of synthetic and real-world PQ disturbances in order to verify the efficacy and applicability of the proposed method. The case studies show that the proposed method provides actual results with respect to the existing TFD-based transient PQ indices, and provides much more accurate results than the traditional fast Fourier transform (FFT) based PQ indices under stationary and nonstationary PQ disturbances. In addition, …

The Role Of Lis1 In Adult Mammalian System, Xu Gao Dec 2014

The Role Of Lis1 In Adult Mammalian System, Xu Gao

Theses and Dissertations

Lis1 haploinsufficiency in humans results in a “smooth brain” phenotype called lissencephaly, and also causes severe cognitive and motor impairments and epilepsy. Seizure severity and frequency typically worsens with time; patients often die within the first decade due to seizure-induced aspiration and pneumonia. Various mouse models have been used to examine the role of Lis1 during brain development, and it is clear that Lis1 regulates a microtubule motor, cytoplasmic dynein. Intriguingly, Lis1 expression remains high in adult brains indicating that it plays a role in mature systems. Indeed, our group found that Lis1 and several related proteins regulate dynein-dependent axon …

Hope Chest: A Memoir Of Home, Marriage, And Objects, Emilie L. Duck Dec 2014

Hope Chest: A Memoir Of Home, Marriage, And Objects, Emilie L. Duck

Theses and Dissertations

As a child, Emilie often imagined what her future home would look like. As she wandered through flea markets with her mother, she would envision the pieces she found there in a home of her own, building spacious libraries, comfortable bedrooms, and well-appointed kitchens in her imagination with the same passion that other children built models out of Legos. Although the houses always changed, there was an underlying certainty that she would eventually have one house—a certainty that could not be realized once she got married, and committed to living wherever the Army stationed her husband. In this memoir, Emilie …

Single Nucleotide Polymorphisms In Dna Repair And Oxidative Stress Genes, And Their Interaction With Antioxidants On Prostate Cancer Aggressiveness, Samuel Antwi Dec 2014

Single Nucleotide Polymorphisms In Dna Repair And Oxidative Stress Genes, And Their Interaction With Antioxidants On Prostate Cancer Aggressiveness, Samuel Antwi

Theses and Dissertations

Prostate cancer is the leading invasive malignancy and the second most common cause of cancer death among American men. Despite compelling evidence that oxidative stress, ineffective DNA damage repair, and habitually low antioxidants intake may act in tandem to influence prostate carcinogenesis, few studies have examined gene-diet interactions involving these risk factors. Even fewer studies have examined such interactions in relation to prostate cancer aggressiveness. This study investigated whether single nucleotide polymorphisms (SNPs) in DNA repair- and oxidative stress-related genes modulated associations between antioxidant intake and prostate cancer aggressiveness. We utilized data from the North Carolina-Louisiana Prostate Cancer Project (PCaP) …

Low Reynolds Number Turbulence: Mechanisms And Applications, Wei Zhao Dec 2014

Low Reynolds Number Turbulence: Mechanisms And Applications, Wei Zhao

Theses and Dissertations

Turbulence, as one of "the most important unsolved classical problem in physics" (R. Feynman, 1932), has been investigated for more than 130 years. Conventionally, turbulence is believed to be a phenomenon of high Reynolds numbers (Re). However, we find that turbulence can also be achieved at low Re by proper external forcing, either in macroflows or in microflows. In macroflows, the characteristics of high Re turbulence can be achieved in confined flows, when the bulk flow Re is around 400, by external forcing at its optimal frequency (Wang 2003; Wang 2006). Interestingly, the optimal narrow band of frequency is fixed …

Surface Modification Of Nanoplatelets In Polymer Nanocomposites, Shailesh K. Shori Dec 2014

Surface Modification Of Nanoplatelets In Polymer Nanocomposites, Shailesh K. Shori

Theses and Dissertations

In polymer nanocomposites (PNCs), it is very important that the nanofiller (typically an inorganic) is well-dispersed in an organic polymer matrix. Optimal compatibility results in end-use products such as packaging materials with enhanced properties. In practice, however, this is challenging to achieve because “ideal” dispersions require the complete uniform separation, termed exfoliation, of the nanofiller within the matrix. As a result, different nanofillers including calcium niobate (CN) and montmorillonite (MMT) are first studied for their ability to exfoliate in aqueous suspensions by measuring the organic cation uptake. The cation exchange capacity, or CEC, determined that CN needs further work before …

Applications Of Advanced Imaging Methods: Macro-Scale Studies Of Woven Composites And Micro-Scale Measurements On Heated Ic Packages, Siming Guo Dec 2014

Applications Of Advanced Imaging Methods: Macro-Scale Studies Of Woven Composites And Micro-Scale Measurements On Heated Ic Packages, Siming Guo

Theses and Dissertations

As a representative advanced imaging technique, the digital image correlation (DIC) method has been well established and widely used for deformation measurements in experimental mechanics. This methodology, both 2D and 3D, provides qualitative and quantitative information regarding the specimen’s non-uniform deformation response. Its full-field capabilities and non-contacting approach are especially advantageous when applied to heterogeneous material systems such as fiber-reinforced composites and integrated chip (IC) packages. To increase understanding of damage evolution in advanced composite material systems, a series of large deflection bending-compression experiments and model predictions have been performed for a woven glass-epoxy composite material system. Stereo digital image …

Diversity, Genetics, And Health Benefits Of Sorghum Grain, Davina Rhodes Dec 2014

Diversity, Genetics, And Health Benefits Of Sorghum Grain, Davina Rhodes

Theses and Dissertations

Staple cereal crops provide the majority of nutrients to the world's population, and thus, can significantly impact human nutrition and health. Phenotypic and genetic diversity within a crop can be useful for biofortification and crop improvement, but quantitative phenotyping is needed to identify varieties with high or low concentrations of a nutrient of interest, and to identify alleles responsible for quantitative trait variation of the nutrient. Sorghum [Sorghum bicolor (L.) Moench] is a diverse and widely adapted cereal crop that provides food for more than 500 million people in sub-Saharan Africa and Asia, and is becoming increasingly popular in specialty …

Thermal Ecology And Physiology Of An Intertidal Predator-Prey System: Pisaster Ochraceus And Mytilus Californianus, Cristian J. Monaco Dec 2014

Thermal Ecology And Physiology Of An Intertidal Predator-Prey System: Pisaster Ochraceus And Mytilus Californianus, Cristian J. Monaco

Theses and Dissertations

Untangling natural systems’ complexity requires understanding the mechanisms responsible for organisms’ responses to environmental change. Recently, significant advances have been made by recognizing the relevance of direct and indirect effects, which take place when multiple biotic and abiotic factors influence each other. I examined potential direct effects of environmental variables on a predator-prey interaction, as well as potential indirect effects of these variables on the interaction itself. I placed emphasis on behavioral and physiological adaptations, which would potentially contribute/modify these effects. My study system was comprised of a rocky intertidal keystone predator, the sea star Pisaster ochraceus, and its main …

Revising For Genre: Mary Robinson's Poetry From Newspaper Verse To Lyrical Tales, Shelley Aj Jones Dec 2014

Revising For Genre: Mary Robinson's Poetry From Newspaper Verse To Lyrical Tales, Shelley Aj Jones

Theses and Dissertations

This dissertation focuses on Mary Robinson’s Lyrical Tales, not as the culminating point to which her writing inevitably led, as is frequently imagined in accounts of her life and work, but, instead, as the product of an intricate process of revision that highlights her investment in genre. Versions of many of the poems that Robinson included in Lyrical Tales originally were published in newspapers and periodicals. Rather than seeing the changes as a move toward a best or most mature or inspired version, I argue that Robinson revised to meet the requirements of her new genre, the lyrical tale. I …

A Three-Dimensional-Engineered Matrix To Study The Microenvironment Of Cancer Stem Cells, Samaneh Kamali Sarvestani Dec 2014

A Three-Dimensional-Engineered Matrix To Study The Microenvironment Of Cancer Stem Cells, Samaneh Kamali Sarvestani

Theses and Dissertations

Maintenance of cancer stem cells (CSCs) is regulated by their microenvironment. As cancer cells are affected by many factors in their microenvironment, a major challenge is to isolate the effect of a specific factor on CSCs while keeping other factors unchanged. We developed a synthetic inert 3D Poly Ethylene Glycol Di-Acrylate (PEGDA) gel culture system as a unique tool to study the effect of microenvironmental factors on CSCs response. Synthetic hydrogels provide the flexibility to design three-dimensional (3D) matrices to isolate and study individual factors in the tumor microenvironment. The first objective of this work was to investigate the effect …

Experimental And Theoretical Studies Of Native And Engineered Vascular Tissue Mechanics, Boran Zhou Dec 2014

Experimental And Theoretical Studies Of Native And Engineered Vascular Tissue Mechanics, Boran Zhou

Theses and Dissertations

Background: Implantation of vascular grafts provides a means to restore blood flow in compromised regions of the circulatory system, and thus is used to treat a wide range of cardiovascular diseases. Despite significant advancements in autologous grafting strategies as well as the engineering of synthetic alternatives, mechanical, structural, and compositional incongruities between the graft and the host artery remain as contributing factors to graft failure. The typical failure modality manifests as proximal anastomotic intimal hyperplasia, which places restrictions on the host vessel size currently treated with grafting strategies (> 5 mm internal diameter). In order to improve long-term clinical outcomes, …

Bio-Active Degradable Micellar Hydrogels For Osteogenic Differentiation Of Mesenchymal Stem Cells, Seyedsina Moeinzadeh Dec 2014

Bio-Active Degradable Micellar Hydrogels For Osteogenic Differentiation Of Mesenchymal Stem Cells, Seyedsina Moeinzadeh

Theses and Dissertations

A feasible approach to the restoration of injured bone tissue is the use of tissue engineering strategies to deliver mesenchymal stem cells (MSCs) to the site of regenration in degradable, in-situ gelling, bio-active hydrogels. Although inert Polyethylene glycol (PEG) hydrogels provide flexibility in controlling the cell microenvironment, their use for in vivo applications in tissue regeneration is limited by their persistence (nondegradability) in the site of regeneration. In an attempt to produce inert hydrolytically degradable matrices for encapsulation of MSCs, hydrogels based on star PEG macromonomers chain-extended with short hydroxy acid (HA) segments (SPEXA) were synthesized and characterized with respect …

Perception Of Police In Public Housing Communities, Taylor Brickley Dec 2014

Perception Of Police In Public Housing Communities, Taylor Brickley

Theses and Dissertations

Research on the relationship between police and citizens consistently finds that attitudes toward police (ATP) are least positive among black citizens in areas of concentrated disadvantage. While much of the research in this area focuses specifically on ATP among young black males in low-income communities because they have the most contact with police, there has been relatively little research that has included older and/or female residents. Additionally, research has yet to examine ATP in racial and economic enclaves that may have different social and environmental characteristics than the surrounding community. This study utilizes in-depth interviews with 60 residents of two …
