Typical variations in the channel width, height, and undercut that may occur with manufactured metal plates are studied. These sample-to-sample variations and distributions are studied and compared with laboratory-scale graphite plates. The goal of the work is to …

Literacy Crisis, Technology, And The Radical Reversal Of Power, Erin Michelle Cromer

Theses and Dissertations

As new media is changing the way individuals communicate, efforts have already been made within universities to, once again, construct new literacy standards in the digital age, producing the appearance of a literacy crisis. I argue that rather than producing another literacy crisis, the fundamental reversal of the power structure concerning who dominates standard literacy places greater expectations on composition scholars and practitioners--rather than students--ultimately providing the conditions of possibility for using power productively to imagine a new pedagogy of rhetorical dexterity that reverses the role of expectations from standards to invention. Such a pedagogy offers rhetoric and composition a …

A Veterinary Science Initiative: An Analysis Of Impact And Future Directions For Humane Education And Collaborative Partnerships, Brittany Watson Tisa

Theses and Dissertations

Humane education research is limited in its scope and structure and this has led to its inability to find a place in standard curriculum. As resources become scarcer for school districts and shelters, proving efficacy of programs is essential for successful partnerships and program achievements. VSI: Veterinary Science Initiative is a program developed by the education team at the Charleston Animal Society as a model for cooperative education between shelters, veterinarians, and other private organizations to collaborate with local school districts, while also conducting research about how this curriculum benefits student knowledge, organizational awareness, and community engagement.

Public Intellectuals: Styles, Publics, And Possibilities, Matthew David Kay

Theses and Dissertations

The status of the public intellectual is debated continuously in the United States, but what is not up for debate or theoretical examination is how public intellectual practice is mediated between style and publics. To that end, this study examines three public intellectual figures: Saul Alinsky, Noam Chomsky, and Robert Reich. Each examination analyzes and describes particular public intellectual styles — performances of culture — which trace three dominant public intellectual practices. These styles contain, invite, and deploy certain publics to engage with the public intellectual and vice versa. First, the study is a theoretical engagement with public intellectual practice …

"The Hollow Men": Divorce And Manhood In The Novels Of Howells, James, And Wharton, Melissa Pluta Parker

Theses and Dissertations

This project examines the relationship between divorce and masculinity as presented in several realist novels written around the turn of the century, including A Modern Instance by William Dean Howells, What Maisie Knew by Henry James, and The Custom of the Country by Edith Wharton. It looks closely at how divorce, which saw a dramatic rise between the years 1880 and 1920, seemingly threatened an elite version of manhood that was already on the decline at this time, a version of manhood increasingly viewed within society as weak and effeminate and one represented in each of these novels by a …

This collection consists of five sections, submitted in partial fulfillment of University of South Carolina's Master of Fine Arts degree in Creative Writing.

Dislocation Reduction In Silicon Doped High Aluminum Content Algan Layers For Deep Uv Optoelectronic Devices, Hung-Chi Chen

Theses and Dissertations

III-Nitride based deep ultraviolet (UV) light emitting diodes (LEDs) are prospective candidates to replace the conventional bulky, expensive and environmentally harmful mercury lamp as new UV light sources, used in the applications of water and air purification, germicidal and biomedical instrumentation systems, etc. Due to the lack of native substrates and poor carrier injection, AlGaN-based deep UV LED is suffering from low optical power and low overall efficiency, which prevents the availability of low cost, high efficiency deep UV LED on the market.

This dissertation is focused on improving the efficiency of deep UV LEDs, by improving the base template …

Iii-V Nitride Micro- And Nano-Scale Cantilevers For Multimodal Sensing Applications, Ehtesham Bin Quddus

Theses and Dissertations

Recent research trends in chemical and biological sensing have been geared toward developing molecular sensor devices that are fast, label free, miniaturized and portable. The performance of these devices can be dramatically improved by utilizing multimodal detection techniques, new materials and micro-/nanofabrication technologies. This is especially true for micro-/nanoscale cantilever sensors, which undergo changes in mechanical or electrical properties upon the specific binding of molecules. To develop the sensor devices with the above attributes, we utilized III-V nitride materials: InN nanowires for realizing nanoscale cantilevers and AlGaN/GaN heterostuctures with or without embedded HFETs, for developing microcantilevers. There are mainly two …

Biomechanics Of Porcine Renal Artery And The Development Of A Replacment Vessel, Mohamed Gabr

Theses and Dissertations

Mechanical characterization of biological soft tissues is essential in the field of biomedical engineering. In this study several loading experiments have been performed to efficiently characterize the passive mechanical response of both native porcine renal arteries and newly developed tissue constructs. The first aim of these studies is to determine whether there is a difference in mechanical response between the main renal artery and its first branch. After fitting the bi-axial data to a Holzapfel-type constitutive model, the results show that there is no statistical difference between the model parameters for renal artery and the first branch. The only significant …

Teacher Silence In South Carolina Public Schools, Daniel Crockett

Theses and Dissertations

This quantitative study of South Carolina public school teachers investigated how comfortable educators are raising problems or concerns to their administration. Five variables, including years of experience, trust in administration, mobility aspirations, relationship with principal, and content of message were examined to see their influence on teachers' comfort levels when voicing such problems or concerns. In addition, teachers were asked to identify the reasons for being hesitant about raising organizational concerns. The study concluded by determining if comfort level varied in different public school settings (elementary, middle, and high).

The sample consisted of 595 South Carolina public school teachers and …

Quantifying The Effects Of Antibiotics Upon Benthic Diatoms And Marine Benthic Algal Communities, Isaac M. Hagenbuch

Theses and Dissertations

Antibiotics are a cornerstone of modern medicine. Their ability to impair prokaryotic metabolism has saved the lives of many millions of humans in the decades since wide antibiotic usage began. Antibiotic compounds are also widely used in the husbandry of animals that are used for food but, unfortunately, much of the antibiotic mass that goes into humans and animals is excreted unchanged. Those excretions go, directly or indirectly, into aquatic ecosystems. The discovery of this fact has led to a growing global concern about the fate of antibiotics in the environment. This concern is driven by no fewer than three …

Nanoparticle Self-Assembly And Ultrafast Nanomagnet Switching Dynamics, Longfei Ye

Theses and Dissertations

A novel manufacturing technology that offers a low-cost alternative for creating more complex optical materials that are assembled with single-nanometer precision is demonstrated. Using the enormous magnetic field gradients present near the surface of magnetic recording media, colloidally suspended superparamagnetic nanopartilces are self-assembled into patterned microstructures.

The position and shape of these microstructures are precisely controlled by magnetic patterns on the template. The template that can be reprogrammed and reused is magnetically recorded using commercial magnetic recording technology. These microstructures consisting entirely of self-assembled magnetic nanoparticles are then transferred to flexible polymer thin films with patterns maintained. In particular, all-nanoparticle …

Promoting Early Childhood Development Through Community Health Worker Interventions: Implementation And Measurement Issues In Rural Pakistan, Zaeem Haq

Theses and Dissertations

Appropriate nutrition and psychosocial stimulation during the first three years of life can have long-lasting effects on a child's health and development. However, not all children in the world receive adequate nutrition and psychosocial stimulation during this period. There has been enormous interest in developing the evidence on the most effective ways of implementing and assessing early childhood development (ECD) promotion interventions in resource poor settings. Despite the interest, the integration of ECD interventions into pre-existing public health programs, and assessment of these interventions in extended family, rural household environment have not been addressed.

The dissertation research presented here was …

Fishing And Fish Consumption Patterns In The Gullah/Geechee Sea Island Population, Jamelle Heyward Ellis

Theses and Dissertations

The Gullah/Geechee (G/G) people are descendants of West African slaves who remained in seclusion on the Sea Islands of South Carolina, North Carolina, Georgia, and Florida until the end of the Civil War in 1865. In addition to retaining their unique cultural language, they also remain largely a fishing subsistence population. Decades of urban development have reduced the G/G population's access to traditional fishing locations and have increased exposures to environmental contaminants in some bodies of water that are frequently fished by the G/G. Approximately 98.4% of SC rivers and streams and 77.6% of lakes have been assessed for aquatic …

Theses and Dissertations

This study investigates chamber music performances outside of traditional concert venues in the 21st-century U.S. The literature review traces the use of non-traditional venues throughout history from Bach's coffee house concerts to the gallery and loft concerts, which first emerged in the 1950s and 60s. The literature review will also look at the business of classical music established in the 20th century.

The study explores whether new venues have changed the landscape of classical music by interviewing players and concert promoters who present concerts in non-traditional venues as well as owners of popular music venues, which host classical music. Using …

"Heritage To Horizons": The History Of The 1977 International Women's Year Conference In South Carolina, Caitlin Marie Mans

Theses and Dissertations

In 1977, 800 South Carolinians came together in the state's capital of Columbia for a meeting called 'South Carolina Woman: Heritage to Horizons.' It was one of fifty-six state and territorial meetings held as part of the United States' celebration of International Women's Year (IWY.) These meetings culminated in the National Women's Conference held later that year in Houston, Texas. IWY was a federally-funded initiative to enable American women to discuss their concerns and make recommendations for national policy. It was an outgrowth of a United Nations program to advance the status of women worldwide by encouraging each nation to …

Interviews On Main, Amanda Rose Forstrom

Theses and Dissertations

Interviews On Main is the script of a one woman performance piece. It was conceived as an exploration and process of how to develop and write a working script, and later, see the piece come to fruition by producing, acting, and directing it. This solo show process has allowed me to delve into discovering my personal aesthetic in order to make a strong, individual artistic statement. Additionally, this process has helped me to learn how to be a solo creative artist, and to have cultivated individual material to perform when I am not cast professionally.

This thesis includes a table …

Using Singular Value Decomposition In Classics: Seeking Correlations In Horace, Juvenal And Persius Against The Fragments Of Lucilius, Thomas Whidden

Theses and Dissertations

For the purpose of this dissertation, the hypothesis is posited that a programmatic correlation of the poems of Lucilius and the other Satirists reveals a detailed and dense level of intertextuality, especially in those poems which scholars already understand to allude to the genre's inventor. In addition to those poems which are discussed in secondary literature, we have discovered other poems which correlate highly with the corpus of Lucilius, but have been largely ignored. To demonstrate this fact I have devised a method using Singular Value Decomposition. That method is able to discern this subtle intertextuality in both the texts …

A Constructivist Examination Of Counselors' Conceptualization Of "Sexuality": Implications For Counselor Education, Wenndy Dupkoski Mallicoat

Theses and Dissertations

Due to the dialectical dilemma between meeting the demands of the managed health care industry through the adherence to the medical model while promoting an emphasis on wellness, the counseling profession does not promote a consistent definition of sexuality. Using a qualitative, phenomenological approach from a constructivist lens, this study was conducted to examine the construct "sexuality" and "sexuality counseling" from counselors' perspectives. One synchronous online focus group and two online individual interviews were conducted with counselors predominantly in the Southeastern United States. Themes from the data include: Sexuality is multi-dimensional; sexuality is developmental; sexuality counseling is dialectical; and sexuality …

Adoptive Couple V. Baby Girl: Two-And-A-Half Ways To Destroy Indian Law, Marcia A. Yablon-Zug

Faculty Publications

On April 16th, the US Supreme court will hear arguments in the case Adoptive Couple v. Baby Girl. This case involves an Indian child whose attempted adoption by a non-Indian couple in South Carolina violated the provisions of the Indian Child Welfare Act (ICWA). Because of this violation, the family court ordered her return to her biological father. The case has received extensive media attention and has resulted in the vilification of ICWA. Nevertheless, the Court’s decision to hear the case was surprising. The issues in the case are straightforward and the lower courts’ decisions were clearly correct. Consequently, the …

The Effect Of Isostatic Pressing On The Dielectric Properties Of Screen Printed Ba0.5Sr0.5Tio3 Thick Films, Siwei Wang, Lingling Zhang, Jiwei Zhai, Fanglin Chen

Faculty Publications

Ba_0.5Sr_0.5TiO₃ thick films with B₂O₃–Li₂O glass sintering aid were prepared by the screen printing method on Al₂O₃ substrates. A 200 MPa isostatic pressure was applied to the films before sintering. After being sintered at 950^∘C, lower porosity and denser microstructure was obtained compared with the films without isostatic pressing. The dielectric constant and dielectric loss were 238 and 0.0028, respectively. A tunability of 61.7% was obtained for the isostatic pressed films, a 27.8% enhancement compared to unpressurized films. These results suggest that isostatic pressing …

Wave Propagation In Metamaterial Using Multiscale Resonators By Creating Local Anisotropy, Raiz U. Ahmed, Sourav Banerjee

Faculty Publications

Directional guiding, passing or stopping of elastic waves through engineered materials have many applications to the engineering fields. Recently, such engineered composite materials received great attention by the broader research community. In elastic waves, the longitudinal and transverse motion of material particles are coupled, which exhibits richer physics and demands greater attention than electromagnetic waves and acoustic waves in fluids. Waves in periodic media exhibit the property of Bragg scattering and create frequency band gaps in which the energy propagation is prohibited. However, in addition to the Bragg scattering, it has been found that local resonance of artificially designed resonators …
