The Roles Of Inhibition In C. Elegans Locomotion, Lan Deng

Dissertations

Inhibition plays important roles in modulating neural activities at different levels from small synapses to brain regions, and different systems from sensory to motor. To achieve translocation, locomotor systems produce alternation of antagonist muscles, including axial posture and limb movement and alternation. In the nematode C. elegans, a cross-inhibition circuit, involving excitatory cholinergic and inhibitory GABAergic motoneurons, is believed to generate the dorsoventral alternation of body-wall muscles that supports backward undulatory locomotion. This dissertation challenges this prevalent hypothesis, delves into studying different roles of inhibition, and depicts the expression pattern and functional role of ionotropic GABAA receptor, UNC-49, in motoneurons …

Schwann Cells In Combination With Gag-Mimetic Scaffolds For Spinal Cord Repair, Sharareh Hashemi

Dissertations

Spinal cord injury (SCI) being a devastating neurological dysfunction can cause extensive irreversible neuronal loss and axonal damage. Fifty-four cases of spinal cord injury per million people occur annually in the United States. Due to the loss of glial cells and demyelination of axons, the neuronal function of surviving neurons is disrupted leading to permanent loss of sensory and motor functions. The glial scar formed by astrogliosis at the chronic stage protects undamaged tissues, but it is known to be a major barrier for axonal regeneration. The limited regeneration capacity of spinal cord makes it challenging to successfully treat the …

Dissertations

Soldiers are often exposed to more than one traumatic brain injury (TBI) event over the course of their service. In recent years, more attention has been drawn to the increased risk of neurological deficits caused by the 'blast plus' polytrauma, which typically is a blast trauma combined with other forms of TBI. The objective of this dissertation is to investigate if exposure to a blast TBI predisposes the brain to increased neurological deficits when followed with a second blunt head trauma. The behavioral and neuronal deficits resulting from a blast plus injury involving a mild-moderate blast followed by a mild …

Impact Of Nurse-Initiated Intentional Rounding On Patient Satisfaction Scores On A Surgical Unit, Tina Eslinger-Vaughn

Dissertations

This project focused on nurse-initiated intentional rounding (NIIR) as a new nursing approach to patient care. NIIR anticipates the needs of patients as nurses perform hourly checks on their patients, thereby improving the overall patient experience, and increasing patient satisfaction. This DNP project included a summative program evaluation of the use of NIIR on a 33-bed surgical unit (N = 629 patients), guided by the John Hopkins Nursing Evidence-Based Model and Guidelines (JHNEBP). The program evaluation included comparisons of mean patient satisfaction scores 3 months prior to implementation of NIIR, and 3 months after implementation.

Traditional students are defined by the following characteristics: earns a high school diploma, enrolls full time immediately after finishing high school, are financially dependent on parents, and either do not work during the school year or works part-time (the exception to the rule) (Choy, 2002). A non-traditional nursing student is defined as students who …

Chemoenzymatic Study Of Coa-Linked Rna In Bacteria, Krishna Sapkota

Dissertations

The ability of RNA to store genetic information and to catalyze biochemical transformations led to the speculation of the existence of RNA world before the evolution of contemporary ribonucleoprotein (RNP) world. Recent discovery of RNA molecules containing metabolic cofactors including coenzyme A and its various thioesters at their 5’ end further supported the RNA world hypothesis as these CoA-linked RNA molecules could be the molecular fossils with very ancient origin. As both RNA and Coenzyme A are believed to have co-existed since last universal common ancestor (LUCA) or even before, the CoA-RNA conjugates in current biology may reveal fundamental molecular …

Turtles are among one of the most imperiled vertebrate groups on the planet with more than half of all species worldwide listed as threatened, endangered or extinct by the International Union of the Conservation of Nature. The Southeastern United States is a global biodiversity hotspot for turtles, and it likely represents the last area on the planet of both high diversity and high abundance of turtle species. In the past century, there has been an exponential increase in the number of publications on turtles in the United States and Canada, however a recent review of the literature suggests that this …

A View From Above: Alternative Perspectives On Smallholder Livelihoods And Agrobiodiversity Conservation In Northern Ecuador, Chris Hair

Dissertations

Food security and deintensification of agriculture are serious concerns in Latin America. Agriculture, especially at small-scale subsistence levels, is hard work, and comes with some economic and physical risk. Transitions from traditional multi-cropping to mono-cropping systems introduce two particular risks that are new to most smallholders: (1) the loss of agricultural diversity and (2) the potential for widespread failure when focusing on the cultivation of a single crop. This research explores how Small Unmanned Aerial Systems (sUAS), or drones, can be used for rapid inventories of crop diversity and to enhance crop management techniques on small-scale farms. In the community …

Collective Protesting As Existential Communication: A Phenomenology Of Risk, Responsibility, And Ethical Attendance, L. Shelley Rawlins

Dissertations

This dissertation explores the experience of participating in collective protest. I performed an existential-phenomenological analysis of five participants’ in-depth accounts of their involvements participating in collective protest. I considered my interviewees’ discourse to be reflective of their lived, embodied experiences of being in protest with others. Participants each described distinct protesting experiences. I explored their accounts in relation to six basic aspects of existence: self, other, embodiment, time, space, and choice/freedom. From within these existential realms, participants’ accounts revealed five key existential themes of participating in collective protest: (1) Existential Crises and Activation; (2) Existential Magnification; (3) Existential Horizons; (4) …

“From Behind The Plow”: Agrarianism And Racial Uplift In African American Literature, 1881-1917, James O'Donoghue

Dissertations

My study challenges our current valorization of movement and flow in readings of African American literature. I do so through an exploration of the representations of the black agrarian masses who either choose to remain or could not afford the spectacular forms of escape to urban life which many essentialized as freedom. In the dramatic and pivotal decades following emancipation, African American leaders attempted to check the growing apartheid by the “combination” of diverse African American communities: North and South, professional and working class. This required that they move beyond the question of whether one was free or slave to …
