Two Southern Women Writers: The Civil War Journals Of Emily Jane Liles Harris And Mary Boykin Chesnut, Robert L. Wilson Dec 2017

Two Southern Women Writers: The Civil War Journals Of Emily Jane Liles Harris And Mary Boykin Chesnut, Robert L. Wilson

Graduate Theses

Through the examination of primary texts, along with appropriate secondary criticism, I argue that Southern women during the Civil War were not the mythological “Southern Belle” that they have often been portrayed as, but that they were intelligent, strong, and passionate writers. I examine the farm journal of Emily Jane Liles Harris and contrast it to the private journal kept by Mary Boykin Chesnut, to explore the role that education and literacy, writing, and authorial voice played in women’s lives during the War. Close attention to the role education and background played in the lives of these women, the uniqueness …

Preoperative mapping of language areas using fMRI greatly depends on the paradigms used, as different tasks harness distinct capabilities to activate speech processing areas. In this study, we compared the ability of 3 covert speech paradigms: Silent Sentence Completion (SSC), category naming (CAT) and verbal fluency (FAS), in localizing the Wernicke's area and studied the association between genomic markers and functional activation. Fifteen right-handed healthy volunteers and 35 mixed-handed patients were included. We focused on the anatomical areas of posterosuperior, middle temporal and angular gyri corresponding to Wernicke's area. Activity was deemed significant in a region of interest if P < 0.05. Association between fMRI activation and genomic mutation status was obtained. Results demonstrated SSC's superiority at localizing Wernicke's area. SSC demonstrated functional activity in 100% of cancer patients and healthy volunteers; which was significantly higher than those for FAS and CAT. Patients with 1p/19q non-co-deleted had higher extent of activation on SSC (P < 0.02). Those with IDH-1 wild-type were more likely to show no activity on CAT (P < 0.05). SSC is a robust paradigm for localizing Wernicke's area, making it an important clinical tool for function-preserving surgeries. We also found a correlation between tumor genomics and functional activation, which deserves more comprehensive study.

Unregulated Space: Text-Messaging Habits As A Predictor Of Punctuation Errors In The Academic Writing Of College Students, Robert Ryan Achuff Dec 2017

Unregulated Space: Text-Messaging Habits As A Predictor Of Punctuation Errors In The Academic Writing Of College Students, Robert Ryan Achuff

Doctoral Dissertations and Projects

Most college-aged students use text messaging to communicate with others (Smith, 2011). Text messaging, though it requires a writer to be concise, makes allowances for “textese,” an informal register of English. At the same time, college students and college graduates are expected to be proficient in writing. Using a theoretical framework influenced by self-regulation (Bandura, 1986), memory (Bartholomae, 1980; Flower & Hayes, 1981; Hayes, 1996; Hayes & Chenoweth, 2006; Kellogg, 2006), and transfer (Perkins & Salomon, 1992; Salomon & Perkins, 1989), a correlational study was conducted to compare the participants’ text messaging habits to participants’ frequency of punctuation errors in …

The Impact Of Financial Aid On Graduation Rates For First-Year Developmental Community College Students In North Carolina, Eric Douglas Barnes Dec 2017

The Impact Of Financial Aid On Graduation Rates For First-Year Developmental Community College Students In North Carolina, Eric Douglas Barnes

Doctoral Dissertations and Projects

One of the most significant issues in post-secondary education is persistence. In community colleges, retention and graduation rates are very low. This is especially true for students enrolled in developmental English, reading, and/or math courses. The low cost of community college tuition and fees combined with financial need-based programs in the form of Pell Grants, give all students, including students academically unprepared who require developmental courses, access to a college education and the means to persist and complete a degree program. However, despite the financial resources, these students are not persisting and completing a degree program. This study will be …

The Public’S Perception Of Humanlike Robots: Online Social Commentary Reflects An Appearance-Based Uncanny Valley, A General Fear Of A “Technology Takeover”, And The Unabashed Sexualization Of Female-Gendered Robots, Megan K. Strait, Cynthia Aguillon, Virginia Contreras, Noemi Garcia Dec 2017

The Public’S Perception Of Humanlike Robots: Online Social Commentary Reflects An Appearance-Based Uncanny Valley, A General Fear Of A “Technology Takeover”, And The Unabashed Sexualization Of Female-Gendered Robots, Megan K. Strait, Cynthia Aguillon, Virginia Contreras, Noemi Garcia

Computer Science Faculty Publications

Towards understanding the public’s perception of humanlike robots, we examined commentary on 24 YouTube videos depicting social robots ranging in human similarity – from Honda’s Asimo to Hiroshi Ishiguro’s Geminoids. In particular, we investigated how people have responded to the emergence of highly humanlike robots (e.g., Bina48) in contrast to those with more prototypically-“robotic” appearances (e.g., Asimo), coding the frequency at which the uncanny valley versus fears of replacement and/or a “technology takeover” arise in online discourse based on the robot’s appearance. Here we found that, consistent with Masahiro Mori’s theory of the uncanny valley, people’s commentary reflected an aversion …

Adaptive Mating Memory: Attractiveness And Contextual Effect On The Remembering And Misremembering Of Potential Mates’ Faces, Peter Kay Chai Tay Dec 2017

Adaptive Mating Memory: Attractiveness And Contextual Effect On The Remembering And Misremembering Of Potential Mates’ Faces, Peter Kay Chai Tay

Dissertations and Theses Collection (Open Access)

Research on adaptive memory demonstrates that words and objects are remembered better if they are evaluated in relation to their survival or reproductive fitness value. Using the error management theory as a framework to elucidate memory biases emerging from adaptive costs and benefits, the present research examined if memory is enhanced for faces of potential mates (i.e., opposite sex individuals) in an ancestral context when the facial attractiveness and the observer’s short-term mating motive were also considered (i.e., Adaptive mating memory). In two studies, participant read scenarios depicting survival threats, mating, or modern environment, and were told to rate a …

Effect Of Explosive Charge Geometry On Shockwave Propagation, Catherine E. Johnson, Phillip R. Mulligan, Kelly Williams, Martin Langenderfer, Jeffrey Heniff Dec 2017

Effect Of Explosive Charge Geometry On Shockwave Propagation, Catherine E. Johnson, Phillip R. Mulligan, Kelly Williams, Martin Langenderfer, Jeffrey Heniff

Mining Engineering Faculty Research & Creative Works

With advancements in the 3D printing of explosives, the understanding how the shape of an explosive charge influences the energy expansion and subsequently the focusing of energy is becoming increasingly more important. Theoretically, explosive charges could be printed to focus the energy on targets of interest or to synthesize nanomaterials. The first step to quantifying the energy expansion and shock wave convergences for a 3D printed charge is to examine simple geometries of traditional explosive charges (non-3D printed). Detonation of 15 PETN-based primasheet charges in the spherical, cubic, cylindrical, and tetrahedral configurations have been examined in this study. Qualitative data …

Long-Range Interactions For Hydrogen: 6p-1s And 6p-2s Systems, Ulrich D. Jentschura, Chandra M. Adhikari Dec 2017

Long-Range Interactions For Hydrogen: 6p-1s And 6p-2s Systems, Ulrich D. Jentschura, Chandra M. Adhikari

Physics Faculty Research & Creative Works

The collisional shift of a transition constitutes an important systematic effect in highprecision spectroscopy. Accurate values for van der Waals interaction coefficients are required in order to evaluate the distance-dependent frequency shift. We here consider the interaction of excited hydrogen 6P atoms with metastable atoms (in the 2S state), in order to explore the influence of quasi-degenerate 2P and 6S states on the dipole-dipole interaction. The motivation for the calculation is given by planned high-precision measurements of the transition. Due to the presence of quasi-degenerate levels, one can use the non-retarded approximation for the interaction terms over wide distance ranges.

Estimating The Contribution Of Dynamical Ejecta In The Kilonova Associated With Gw170817, Benjamin P. Abbott, Marco Cavaglia, For Full List Of Authors, See Publisher's Website. Dec 2017

Estimating The Contribution Of Dynamical Ejecta In The Kilonova Associated With Gw170817, Benjamin P. Abbott, Marco Cavaglia, For Full List Of Authors, See Publisher's Website.

Physics Faculty Research & Creative Works

The source of the gravitational-wave (GW) signal GW170817, very likely a binary neutron star merger, was also observed electromagnetically, providing the first multi-messenger observations of this type. The two-week-long electromagnetic (EM) counterpart had a signature indicative of an r-process-induced optical transient known as a kilonova. This Letter examines how the mass of the dynamical ejecta can be estimated without a direct electromagnetic observation of the kilonova, using GW measurements and a phenomenological model calibrated to numerical simulations of mergers with dynamical ejecta. Specifically, we apply the model to the binary masses inferred from the GW measurements, and use the …

We report results of a deep all-sky search for periodic gravitational waves from isolated neutron stars in data from the first Advanced LIGO observing run. This search investigates the low frequency range of Advanced LIGO data, between 20 and 100 Hz, much of which was not explored in initial LIGO. The search was made possible by the computing power provided by the volunteers of the Einstein@Home project. We find no significant signal candidate and set the most stringent upper limits to date on the amplitude of gravitational wave signals from the target population, corresponding to a sensitivity depth of 48.7 …

First Narrow-Band Search For Continuous Gravitational Waves From Known Pulsars In Advanced Detector Data, Benjamin P. Abbott, Marco Cavaglia, For Full List Of Authors, See Publisher's Website.

Physics Faculty Research & Creative Works

Spinning neutron stars asymmetric with respect to their rotation axis are potential sources of continuous gravitational waves for ground-based interferometric detectors. In the case of known pulsars a fully coherent search, based on matched filtering, which uses the position and rotational parameters obtained from electromagnetic observations, can be carried out. Matched filtering maximizes the signal-to-noise (SNR) ratio, but a large sensitivity loss is expected in case of even a very small mismatch between the assumed and the true signal parameters. For this reason, narrow-band analysis methods have been developed, allowing a fully coherent search for gravitational waves from known pulsars …

Physics Faculty Research & Creative Works

On 2017 June 8 at 02:01:16.49 UTC, a gravitational-wave (GW) signal from the merger of two stellar-mass blackholes was observed by the two Advanced Laser Interferometer Gravitational-Wave Observatory detectors with a network signal-to-noise ratio of 13. This system is the lightest black hole binary so far observed, with component masses of 12+7 -2M⊙+2-2M⊙ (90% credible intervals). These lie in the range of measured black hole masses in low-mass X-ray binaries, thus allowing us to compare black holes detected through GWs with electromagnetic observations. The source's luminosity distance is 340+140 -140 corresponding to redshift -0.07 …

On 2017 August 17 the merger of two compact objects with masses consistent with two neutron stars was discovered through gravitational-wave (GW170817), gamma-ray (GRB 170817A), and optical (SSS17a/AT 2017gfo) observations. The optical source was associated with the early-type galaxy NGC 4993 at a distance of just ∼40 Mpc, consistent with the gravitational-wave measurement, and the merger was localized to be at a projected distance of ∼2 kpc away from the galaxy's center. We use this minimal set of facts and the mass posteriors of the two neutron stars to derive the first constraints on the progenitor of GW170817 at the …

A nematic topological superconductor has an order parameter symmetry, which spontaneously breaks the crystalline symmetry in its superconducting state. This state can be observed, for example, by thermodynamic or upper critical field experiments in which a magnetic field is rotated with respect to the crystalline axes. The corresponding physical quantity then directly reflects the symmetry of the order parameter. We present a study on the superconducting upper critical field of the Nb-doped topological insulator NbxBi2Se3 for various magnetic field orientations parallel and perpendicular to the basal plane of the Bi2Se3 layers.
