The Ethics Of Representation: Muslim Women Reenacting And Resisting Whiteness, Haneen Al Ghabra Jan 2017

The Ethics Of Representation: Muslim Women Reenacting And Resisting Whiteness, Haneen Al Ghabra

Electronic Theses and Dissertations

This study examines Muslim women's performances and embodiment of White femininity. It addresses invisibility/visibility and problematic rhetorical constructs for re-securing and replicating White femininity, which in turn reasserts White masculinity as the dominant ideological structure in service of Whiteness. To be exact, the aim is to specifically focus on how Whiteness travels globally through Muslim bodies and subjects who speak the language of the imperialist and not the vernacular. This language of the imperialist is also the language of heteronormativity, class, and educational privilege. These intersections are not stand-alone categories but instead seep into one another in the service of …

Developing A Parameterization Approach For Soil Erodibility For The Rangeland Hydrology And Erosion Model (Rhem), Osama Z. Al-Hamdan, Frederick B. Pierson, Mark A. Nearing, Christopher Jason Williams, Mariano Hernandez, Jan Boll, Sayjro K. Nouwakpo, Mark A. Weltz, Kenneth Spaeth Jan 2017

Developing A Parameterization Approach For Soil Erodibility For The Rangeland Hydrology And Erosion Model (Rhem), Osama Z. Al-Hamdan, Frederick B. Pierson, Mark A. Nearing, Christopher Jason Williams, Mariano Hernandez, Jan Boll, Sayjro K. Nouwakpo, Mark A. Weltz, Kenneth Spaeth

Articles

Soil erodibility is a key factor for estimating soil erosion using physically based models. In this study, a new parameterization approach for estimating erodibility was developed for the Rangeland Hydrology and Erosion Model (RHEM). The approach uses empirical equations that were developed by applying piecewise regression analysis to predict the differences of erodibility before and after disturbance (i.e., wildfire, prescribed fire, and tree encroachment) and across a wide range of soil textures as a function of vegetation cover and surface slope angle. The approach combines rain splash, sheet flow, and concentrated flow erodibilities into a single parameter for modeling erodibility …

Determination Of Novel Metabolites Of Therapeutic Agents Used In The Treatment Of Castration-Resistant Prostate Cancer, Mohammad Alyamani Jan 2017

Determination Of Novel Metabolites Of Therapeutic Agents Used In The Treatment Of Castration-Resistant Prostate Cancer, Mohammad Alyamani

ETD Archive

Despite an array of improved treatment options over the past decade, prostate cancer remains the second leading cause of cancer mortality for men in the United States. Abiraterone and galeterone are oral steroidal compounds that are used to treat metastatic castration-resistant prostate cancer (CRPC). Abiraterone blocks 17a-hydroxylase/17,20-lyase (CYP17A1), an enzyme required for androgen synthesis. Galeteron inhibits CYP17A1, blocks the androgen receptor (AR), and decreases AR protein levels. Both drugs share the same structure with endogenous androgens such as dehydroepiandrosterone, which are substrates for the enzyme, 3ß-hydroxysteroid dehydrogenase (3ßHSD). Metabolites of 3ßHSD undergo further metabolism to produce the AR ligand, testosterone …

The Effect Of Site Characteristics On The Reproductive Output Of Lesser Celandine (Ranunculus Ficaria), Justin P. Kermack Jan 2017

The Effect Of Site Characteristics On The Reproductive Output Of Lesser Celandine (Ranunculus Ficaria), Justin P. Kermack

ETD Archive

Ranunculus ficaria L., an ephemeral perennial invasive plant brought over from Europe, is becoming widespread throughout the Northeastern United States. This herbaceous buttercup is able to create extensive dense mats that limit native species growth. Taking advantage of an early growing season and rapid reproduction rates, this species can create dense monocultures, which threatens native communities and ecosystems. Elimination of native spring ephemerals results in decreased biodiversity. A better understanding of how R. ficaria responds to site characteristics is needed to prioritize management efforts toward high-risk sites.

Ranunculus ficaria abundance and reproductive output (seed, bulbil and tuber production rates) were …

Piv Analysis Of Wake Structure Of Real Elephant Seal Whiskers, Joseph Antun Bunjevac Jan 2017

Piv Analysis Of Wake Structure Of Real Elephant Seal Whiskers, Joseph Antun Bunjevac

ETD Archive

Seals are able to accurately detect minute disturbances in the ambient flow
environment using their whiskers, which is attributed to the exceptional capability of
their whiskers to suppress vortex-induced vibrations in the wake. To explore potential applications for designing smart flow devices, such as high-sensitivity underwater
flow sensors and drag reduction components, researchers have studied how the role
of some key parameters of whisker-like morphology affect the wake structure. Due to
the naturally presented variation in size and curvature along the length of whiskers,
it is not well understood how a real whisker changes the surrounding flow and the
vortex …

Teacher Motivation Matters: An Hlm Approach To Understanding Motivation Towards The International Baccalaureate Middle Years Programme, John Murphy Moore Jan 2017

Teacher Motivation Matters: An Hlm Approach To Understanding Motivation Towards The International Baccalaureate Middle Years Programme, John Murphy Moore

ETD Archive

The International Baccalaureate Organization’s Middle Years Programme (IBMYP) has experienced explosive growth in the United States since its early stages in 1994. Despite its aggressive expansion, little research has explored the relationship between teachers and the program, ignoring the role of motivation in the ways in which the external standards and practices of the program are internalized and enacted. External regulation threatens teachers’ autonomous motivation and is thus associated with compliance attitudes, increased burnout, and less autonomy-support in the classroom. Conversely, teachers who experience more autonomous motivation are generally more creative, resist burnout, and inspire lifelong learning in students.

Using Nucleotide Analogs As Biochemical Probes To Evaluate The Mechanisms Involved In Translesion Replication By A High Fidelity Dna Polymerase, Anvesh Dasari Jan 2017

Using Nucleotide Analogs As Biochemical Probes To Evaluate The Mechanisms Involved In Translesion Replication By A High Fidelity Dna Polymerase, Anvesh Dasari

ETD Archive

Translesion DNA synthesis (TLS) allows DNA polymerases to incorporate nucleotides opposite and beyond damaged DNA. This activity is an important risk factor for the initiation and progression of genetic diseases including cancer. My study evaluates the ability of a high-fidelity DNA polymerase to perform TLS with 8-oxo-guanine, a pro-mutagenic DNA lesion formed by reactive oxygen species. Using modified purine and non-natural indole analogs as biochemical probes, I have evaluated the influence of desolvation, hydrogen bonding interactions, and shape complementarity towards nucleotide binding and incorporation opposite the miscoding lesion 8-oxo-guanine by the high fidelity gp43exo- DNA polymerase. In Chapter II, I …

Evaluation Of A Microfluidic Mixer Utilizing Staggered Herringbone Channels: A Computational Fluid Dynamics Approach, Brian Hama Jan 2017

Evaluation Of A Microfluidic Mixer Utilizing Staggered Herringbone Channels: A Computational Fluid Dynamics Approach, Brian Hama

ETD Archive

Microfluidic platforms offer a variety of advantages including improved heat transfer, low working volumes, ease of scale-up, and strong user control on parameters. However, flow within microfluidic channels occurs at low Reynolds numbers, which makes mixing difficult to accomplish. Adding V-shaped ridges to channel walls, a pattern called the staggered herringbone design (SHB), might alleviate this problem by introducing transverse flow patterns that enable enhanced mixing. However, certain factors affecting the SHB mixer’s performance remain largely unexplored.

In this work, a microfluidic mixer utilizing the SHB geometry was developed and characterized using computational fluid dynamics based simulations and complimentary experiments. …

Eldritch Horrors: The Modernist Liminality Of H.P. Lovecraft's Weird Fiction, Dale Allen Crowley Jan 2017

Eldritch Horrors: The Modernist Liminality Of H.P. Lovecraft's Weird Fiction, Dale Allen Crowley

ETD Archive

In the early part of the twentieth century, the Modernist literary movement was moving into what was arguably its peak, and authors we would now unquestioningly consider part of the Western literary canon were creating some of their greatest works. Coinciding with the more mainstream Modernist movement, there emerged a unique sub- genre of fiction on the pages of magazines with titles like Weird Tales and Astounding Stories. While modernist writers; including Marcel Proust, Virginia Woolf, Ernest Hemingway, D.H. Lawrence, James Joyce, Ezra Pound, William Faulkner, and T.S. Elliot – among others – were achieving acclaim for their works; in …

Developmental Disabilities And Family Dynamics, Meghan Murray Jan 2017

Developmental Disabilities And Family Dynamics, Meghan Murray

ETD Archive

Typically developing (TD) siblings of children with an Intellectual or Developmental Disability (IDD) are among those most influenced by their sibling’s diagnosis. Factors such as increased family stress, lack of family communication, and negative sibling perception can play a role in leading to internalizing and externalizing problems from the TD child. A limit to the existing sibling relationship literature is that the relationships in families with a child with IDD have only been collected via self-report measures through which respondents have been found to fake their responses to avoid being perceived in certain ways. Conversely, implicit measures, such as the …

Cathepsin K Targeting Matrix Regenerative Nanoparticles For Small Abdominal Aortic Aneurysm Repair, Jonathan M. Fox Jan 2017

Cathepsin K Targeting Matrix Regenerative Nanoparticles For Small Abdominal Aortic Aneurysm Repair, Jonathan M. Fox

ETD Archive

Abdominal aortic aneurysms (AAAs) are characterized by the loss of elasticity in the aorta wall leading to a chronic increase in diameter and resulting in rupture. This is due to the lack of regeneration of elastic fibers and chronic proteolytic breakdown of elastic fibers within the aorta mediated by matrix metalloproteinases (MMPs), specifically MMP-2 and -9. Previous studies in our lab have shown cationic amphiphile-surface functionalized poly(lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) loaded with doxycycline (DOX) to inhibit MMP activity and stimulate elastic matrix synthesis, effects we attributed to both low doses (< 10 mg/ml) of DOX released and independent effects of cationic amphiphile pendant groups on the NP surface. This promises application of these NPs to arrest or regress AAA growth since high oral DOX dosing inhibits new elastic matrix formation in the AAA wall and has undesirable side effects. In this study, we investigated feasibility of antibody-based active targeting of intravenously infused NPs to the AAA wall. Cathepsin K, a cysteine protease, is a biomarker for AAA and overexpressed in abdominal aortic aneurysm tissue making it an ideal target moiety. We have shown using a covalent conjugation method of modifying the surface of the NPs with a cathepsin K antibody resulted in a more robust antibody attachment which did not affect the DOX release profile. Cathepsin K expression was confirmed to be localized on the cell surface and utilizing cathepsin K Ab-conjugated NPs, we demonstrated an increased NP localization to the cathepsin K overexpressing cells in vitro and ex vivo. Importantly, the DOX-loaded NPs demonstrated pro-elastogenic and anti-proteolytic effects in aneurysmal smooth muscle cells supporting their use as regenerative therapies to arrest and regress AAA growth. Preliminary data has been collected indicating cathepsin K Ab-conjugated NP targeting to AAAs in elastase-injured rat models. The study outcomes support the feasibility of using cathepsin K Ab-conjugated NPs as a targeted therapy for elastic matrix regeneration in AAA tissue and will serve as a basis for already initiated follow up studies to assess NP biodistribution, in situ retention in the AAA wall, and safety as a function of time.

Therapeutic Potential Of Rhtrail For Malignant Melanoma, Katherine Ann Turner Jan 2017

Therapeutic Potential Of Rhtrail For Malignant Melanoma, Katherine Ann Turner

ETD Archive

The application of recombinant human Tumor Necrosis Factor-Related Apoptosis-Inducing Ligand (rhTRAIL) for the treatment of cancer holds great promise due to its ability to selectively induce apoptosis in cancer cells while not harming normal healthy cells. This is evident by the robust levels of apoptosis induced in malignant melanoma cells while no event of apoptosis was observed in the non-transformed counterpart of melanomas, melanocytes. However, the clinical utility of rhTRAIL is limited due to the heterogeneity seen in rhTRAIL-sensitivity among cancers. rhTRAIL-resistance is especially prevalent in cases of malignant melanoma. Melanoma rhTRAIL-resistance can be attributed to a number of different …

Age And Sex-Specific Effect Of Caloric Restriction On Circadian Clock And Longevity-Associated Gene Expression, Arten Andreyevich Astafev Jan 2017

Age And Sex-Specific Effect Of Caloric Restriction On Circadian Clock And Longevity-Associated Gene Expression, Arten Andreyevich Astafev

ETD Archive

The rhythms in the expression of circadian clock genes are affected by calorie restriction (CR), a dietary paradigm known to increase lifespan. In our current study, we show that circadian rhythms are influenced by sex and the effects of CR are different between males and females. In particular, we found a group of clock genes which showed a sex-dependent difference in expression, as well as in response to CR (Rev-Erb α, Ror γ and both Cryptochromes: Cry1 and Cry2 genes). Two clock genes showed no difference in expression but their response to CR showed sexual dimorphism (Ror α and Rev-Erb …

I Hate It, But I Can't Stop: The Romanticization Of Intimate Partner Abuse In Young Adult Retellings Of Wuthering Heights, Brianna R. Zgodinski Jan 2017

I Hate It, But I Can't Stop: The Romanticization Of Intimate Partner Abuse In Young Adult Retellings Of Wuthering Heights, Brianna R. Zgodinski

ETD Archive

In recent years, there has been a trend in young adult adaptations of Wuthering Heights to amend the plot so that Catherine Earnshaw chooses to have a romantic relationship with Heathcliff, when in Bronte’s novel she decides against it. In the following study, I trace the factors that contribute to Catherine’s rejection of Heathcliff as a romantic partner in the original text. Many critics have argued that her motives are primarily Machiavellian since she chooses a suitor with more wealth and familial connections than Heathcliff. These are indeed factors; however, by engaging with contemporary research on adolescent development, I show …
