Get PDFCommunity Partner: South Cumberland Health Network
The public health team partnered with the South Cumberland Health Network to create a reliable resource to analyze health disparities in the region.
Problem: A wide range of Tennessee health-related information is dispersed across the internet and not organized into one location. Due to the unorganized nature of the health-related information, some hospitals have become overwhelmed with patients due to lack of access.
Solution: The team collected and consolidated the data from various sources into a database which analyzes trends and presents its findings in an online interactive dashboard.
Impact: This project brought together Tennessee health information into one centralized location that will allow for problems to be identified and solutions to be created in response to the findings.South Cumberland Health Networ
Acute exposure of Roundup is sufficient to induce behavioral changes in larval stream salamanders
Get PDFGlyphosate is a commonly used agricultural pesticide that can have non-target effects on a wide range of organisms. Although directly applied to agricultural fields, runoff during rainfall introduces the chemical into surrounding water bodies. In lotic systems, glyphosate accumulates and negatively affects the physiology, development, and behavior of amphibians. However, these known effects stem from chronic exposure relative to acute exposure experienced by amphibians inhabiting adjacent streams. Previous studies demonstrated a dose-dependent decrease in burst distance associated with glyphosate exposure in stream salamanders, but it is unclear whether and how long it might take for individuals to recover from acute exposure. Our objective was to describe the recovery of stream salamander larvae, Eurycea wilderae, to short-term exposure of glyphosate. We observed that exposed individuals recovered from glyphosate exposure between 2 and 4 hours post-exposure. Length of exposure did not affect responses by stream salamander larvae. Concurrently, we also observed decreased burst responses by unexposed animals that could be due to habituation or exhaustion during our trials, and we recommend that future trials minimize the frequency of sampling. Because burst distance is associated with swimming ability, impairment could temporarily increase predation risk, or more significantly, contribute to downstream displacement of larval individuals inhabiting streams in agricultural areas
The Non-Kenotic Christology of William Porcher Dubose: A Response to Francis J. Hall
No full textIn the late nineteenth century, General Theological Seminary professor Francis J. Hall claimed that University of the South professor and fellow Anglican, William Porcher DuBose, subscribed to a kenotic Christology. The goal of this thesis is to evaluate whether this characterization of DuBose’s incarnational theology is warranted. The thesis begins with an exploration of DuBose’s Christology with its personalistic, progressive, and Spirit-based Incarnation. Next Hall’s traditional understanding of the Incarnation, with a Christological union that safeguards attributes of both the divine and human natures, is examined, along with an overview of Hall’s anti-kenotic arguments. Because the Christology of German theologian Isaak August Dorner is the model for DuBose’s theology, and given that Dorner himself was avidly anti-kenotic, a survey of Dorner’s theology follows in the hope that it may illumine elements in DuBose’s Christology that point away from Kenoticism.Circling back to Hall’s claim that DuBose embraces a kenotic Christology, each feature in his theology that resonates with Kenoticism is considered. The conclusion is reached that DuBose’s incarnational theology, with its personalistic view of reality and the gradual union of human and divine natures in Christ, does not fulfill the essential feature of a kenotic Christology – the abandonment or suspension of some attributes of the Logos during the Incarnation. Finally, DuBose’s underlying theological motivation – to articulate an ethical Christological union rooted in mutuality, self-consciousness, and freedom – is presented as an expression of Christian mysticism, although the Personalist worldview that forms the basis of this divine-human union is incongruous with his sympathy for the Confederate South.Benjamin Kin
Tunnel Diode Oscillators for Measuring the Critical Temperature of Superconductors
Get PDFTunnel diode oscillators can be used to measure the critical temperature of a superconductor by monitoring the frequency of oscillation. In my experiment I have constructed an LC to be used in conjunction with a tunnel diode for a stable oscillation. The tunnel diode keeps the oscillation from damping because of its unique characteristic of negative resistance at certain voltages. In order to use the tunnel diode for this purpose, I first measured its IV curve to determine at what voltage it needs to operate. Once this is done, it can be used in the oscillator circuit and set up with the superconductor. The critical temperature of the superconductor is seen as a sudden drop in the graph of frequency of the oscillator as a function of temperature.Department of Physics and Astronom

Get PDFCommunity Partner: 1. Haiti Institute and 2. Ancient Art Archive
Collaborating with the Haiti Institute and the Ancient Art Archive, the Sewanee DataLab photos team applied machine learning techniques to curate photographic evidence of the impact of Sewanee’s work in Haiti.
Problem:
No conclusions or insights have been drawn from the files of photos from Haiti.
Rock art is continuously threatened by people and the environment, and as the rock art disappears so do the stories behind them.
Solution:
Convolutional neural networks were used to quantify objects and humans in the photos, drawing necessary conclusions and insights from the images.
Convolutional neural networks were used to label and digitize rock art objects, allowing the rock art and its stories to be safely stored.
Impact:
The work from the summer measured economic development and informed conversations about development in the community.
The work also created statistical tools for research and preservation of heritage sites.Haiti Institute and Ancient Art Archiv
Silicon Photomultiplier as an Alternative to Traditional PMT
No full textSilicon photomultiplier is a cheaper and more efficient alternative to traditional PMTs. Advantages include low operating voltage, insensitivity to magnetic field and high photon sensitivity. We have used an SiPM coupled with an inch long scintillation crystal. A pre-amp and amplifier circuits were built onsite to interface the signal from the detector to a multi-channel analyzer. Two of these detectors were used as a muon telescope and the result from the telescope was used to confirm the well-known correlation between the zenith angle and distribution of cosmic muons. In a separate experiment, an SiPM and a NaI detector without magnetic shielding were used to collect gamma spectra from Cs-137 and Na-22 sources. The spectroscopy for the SiPM detector was significantly better than the NaI detector

Teaching Wesleyan Grace in a Fractured Post-Modern Church in Central Appalachia
No full textThe United Methodist church in Central Appalachia--Holston Annual Conference in particular-- is a fractured, multi-cultural, multi-theological entity. This project is an effort to recognize the disparate ideologies involved and educate and unite them toward healing and witness based on the understood theology of our founder John Wesley. This educational model is an attempt at healing an abusive past within the congregations of Central Appalachia. It is based primarily on John Wesley's understanding of Grace as a unifying force that develops and grows over time. With the 1968 Uniting Conference, Methodism appears to have lost a large part of its distinctive expression of Grace and has become enmeshed or enculturated to American religious culture, a culture which, since the "Great Awakening" finds its strength in Calvinist theology. I am proposing an educational model with a pastoral approach to educate, or perhaps re-educate, from the top down to the local church level, Wesley's distinctive idea of Grace as it came to him through Arminius. From both his own writings and current modern scholarship on the Wesleyan theology of Grace, I give a brief outline of how he came to believe and live this theology. Then I
develop a brief educational model whose structure is similar to the Wesley small group or society model
