Microfluidic Electrical Impedance Spectroscopy, John J. Foley

Master's Theses

The goal of this study is to design and manufacture a microfluidic device capable of measuring changes in impedance valuesof microfluidic cell cultures. Tocharacterize this, an interdigitated array of electrodes was patterned over glass, where it was then bonded to a series of fluidic networks created in PDMS via soft lithography. The device measured ethanol impedance initially to show that values remain consistent over time. Impedance values of water and 1% wt. saltwater were compared to show that the device is able to detect changes in impedance, with up to a 60% reduction in electrical impedance in saltwater. Cells were …

The Impact Of Cleft Lip And Palate Repair Surgery On Cognitive And Academic Outcomes For Teens In India, R Jeremiah Maller

Master's Theses

India has a backlog of nearly one million patients in need of cleft lip and palate repair. Unrepaired cleft results in social stigma and diminished health, psychological wellbeing, and academic functioning. Cleft repair surgery has the potential to restore functioning in these domains. However, the magnitude of the social, educational, and economic impact of cleft repair surgery has not been evaluated using statistically rigorous methods. An estimation of the academic and educational impact of cleft repair has implications for the appropriate allocation of public health resources. We analyze original data gathered from teenagers in West Bengal, India using the difference-in-differences …

The Effects Of Poor Maternal Nutrition On Offspring Muscle Metabolism, Dominique Martin

Master's Theses

Poor maternal nutrition during gestation alters offspring muscle composition, fiber number, postnatal growth, and stem cell function. Additionally, poor maternal nutrition impacts offspring whole body and stem cell metabolism. We hypothesized that over- or restricted-feeding during gestation would alter muscle myoblast metabolism as well as offspring Longissimus dorsi muscle (LD) metabolome. Pregnant Western White-faced ewes (n = 47) were individually fed 60% (RES), 100% (CON), or 140% (OVER) of NRC requirements starting at d 30.2 ± 0.2 of gestation. At d 90 and 135 of gestation, ewes were euthanized for fetal muscle collection. Another group of ewes were allowed to …

Substance Use, Hiv Serostatus Disclosure, And Sexual Risk Behavior In People Living With Hiv: An Event-Level Analysis, Matthew Sullivan

Master's Theses

Objective. Sexually active people living with HIV (PLWH) face difficult decisions about disclosing their HIV status to sexual partners. Alcohol and other drug use are prevalent in medically engaged PLWH, and could impact these decision-making processes. We sought to examine the event-level relationships between substance use, HIV disclosure, and condom use in PLWH.

Method. Adult PLWH were recruited from care settings in a southeastern US city. Participants reported psychosocial and health information at baseline, and reported their sexual behavior for 28 consecutive days via text message prompts. Multi-level modeling was employed to examine event-level associations between substance use, HIV disclosure, …

A Semi-Supervised Feature Engineering Method For Effective Outlier Detection In Mixed Attribute Data Sets, Girish Srivatsa Rentala

Master's Theses

Outlier detection is one of the crucial tasks in data mining which can lead to the finding of valuable and meaningful information within the data. An outlier is a data point that is notably dissimilar from other data points in the data set. As such, the methods for outlier detection play an important role in identifying and removing the outliers, thereby increasing the performance and accuracy of the prediction systems. Outlier detection is used in many areas like financial fraud detection, disease prediction, and network intrusion detection.

Traditional outlier detection methods are founded on the use of different distance measures …

Improving Communication: Huddling For Change, Harnoor Chahal

Master's Theses

The purpose of this communication improvement project is to incorporate huddles between interdisciplinary departments within a microsystem in order to improve customer satisfaction by decreasing the number of grievances. Based on the increasing number of grievances due to delayed hospital discharge, which results from a lack of communication between team members, there is an increased need for communication between the microsystem. By implementing weekly huddles between the Inpatient and Outpatient nurses, not only will there be increased care-coordination, but there will also be a decreased delay in discharge from the hospital caused by missed or no communication. Evidence-based practice indicates …

Understanding Shared Demand: A Quantitative Investigation Into The Changing Modal Landscape Of New York City, Raymond Gerte

Master's Theses

The concept of shared travel, or making trips with other users via a common vehicle, is far from novel. However, recent technological advances have paved the way for new mobility alternatives within established transportation networks; including on-demand ride hailing/sharing/networking (e.g. Uber, Lyft) and citywide bike sharing systems. This shared concept has flourished and is being hailed as a potential option for autonomous vehicle operation moving forward. However, substantial investigation into how shared mode offerings impact travel behaviors and integrate into existing transportation networks is lacking. To address this, this research explores two main investigations. First, understand the demand for one …

Educational Prevention Program Of Surgical Site Infections (Ssi) At A Metropolitan Pediatric, Daniel Chavez

Master's Theses

Surgical Site Infections are a common hospital acquired disease. The prevention of Surgical Site Infection at a metropolitan pediatric hospital was lacking thorough education on how to prevent Surgical Site Infections. Literature was used to support this educational program with evidence based practices. To further reduce Surgical Site Infections education played a key role. Most importantly the distribution of education is what this educational program aimed toward supporting. In order to optimize patient outcomes through the use of our educational program literacy requirements must be me. Using this information our team constructed educational pamphlets that would help empower patients so …

Educational Prevention Program Of Surgical Site Infections At A Metropolitan Pediatric Hospital, Myra Hasan

Master's Theses

Surgical site infections (SSI) are a common cause of healthcare-associated infections (HAI). They remain a significant problem, as they are associated with increased morbidity and mortality and cause an increase in demand for several healthcare resources. In order to address this problem, hospitals have implemented several protocols and polices that are aimed to reduce these infections. However, the rates of SSIs continue to rise. Healthcare team members have found that while it is their responsibility to enforce preventative measures to the patient in the preoperative and surgical room, patient compliance to preventive measures at home also plays a role.

An Improved Probabilistic Simulation Framework For Gene Family Evolution, Soumya Kundu

Master's Theses

Gene and sub-gene family evolution is usually represented in a framework where domain trees evolve inside one or more gene trees, each of which evolves inside a species tree. The Duplication-Transfer-Loss (DTL) reconciliation and the Domain-Gene-Species (DGS) reconciliation algorithms allow us to infer the evolutionary histories of a given set of species, genes, and protein domains. However, in the absence of biological data regarding the true evolutionary histories of these species, genes, and domains, we must rely on simulated data to validate the accuracy of these methods. Although numerous probabilistic simulation frameworks exist for gene family evolution, none of them …

Iris Biometric Identification Using Artificial Neural Networks, Kevin Joseph Haskett

Master's Theses

A biometric method is a more secure way of personal identification than passwords. This thesis examines the iris as a personal identifier with the use of neural networks as the classifier. A comparison of different feature extraction methods that include the Fourier transform, discrete cosine transform, the eigen analysis method, and the wavelet transform, is performed. The robustness of each method, with respect to distortion and noise, is also studied.

Detecting A Probiotic Product Within The Gut Of Broiler Chickens, Anneka Pisula

Master's Theses

As of January 2017, the U.S. poultry industry banned the use of antibiotics and now relies on alternatives such as probiotics to help protect animal health. Although probiotic use is not a new concept in the poultry industry, identifying the best combination of bacterial strains to generate an effective probiotic formula requires further investigation. This study aimed to detect a probiotic product of four bacterial strains (Pedioccoccus acidilactici, Pediococcus pentosaceus, Lactobacillus plantarum, and Bacillus subtilis) in a feeding trial with broiler chickens. Birds given the probiotic were predicted to show an improved growth performance with …

Quantifying The Environmental Performance Of A Stream Habitat Improvement Project, Cody Morse

Master's Theses

River restoration projects are being installed worldwide to rehabilitate degraded river habitat. Many of these projects focus on stream habitat improvement (SHI), and an estimated 60%of the 37,000 projects listed in the National River Restoration Science Synthesis Program focus on SHI for salmon and trout species. These projects frequently lack a sufficient monitoring program or account for the environmental costs associated with SHI. The present study used life cycle assessment (LCA) techniques and topographic effectiveness monitoring to quantify environmental costs on the basis of geomorphic change. This methodology was a novel approach to assessing the cost-benefit relationship of SHI. To …

Enzymatic Activation Of Cannabinoid Pro-Drugs, Anna Theresa Margiotta

Master's Theses

Cannabinoids have been used throughout history as medical treatments spanning from menstrual cramps in ancient China to enhancing appetite in patients with AIDS or cancer in the modern day. Currently there is research indicating that cannabinoids also have anti-proliferative and pro-apoptotic effects on several strains of cancer cells (Carchman, Harris, & Munson, 1976; Glodde, Jakobs, Bald, Tüting, & Gaffal, 2015; McKallip et al., 2002; Preet, Ganju, & Groopman, 2008; Sánchez, Galve-Roperh, Canova, Brachet, & Guzmán, 1998). The traditional methods for administration of cannabinoids are inhalation or oral; however, for some cannabinoids these may result in undesirable psychoactive side effects. Cell-in-a-Box® …

Mississippi’S First Statewide Teachers’ Strike, Emily Doyne Smith

Master's Theses

This thesis argues that the Education Reform Act of 1982 (ERA) inadvertently led to Mississippi’s first statewide teachers’ strike in 1985 because of the Southeastern pay average clause recommending that the teachers’ pay should reach the average of the southeastern states, if possible. The teachers’ associations in Mississippi used this clause to lobby and promote teachers’ pay to that average. However, after two years of stagnated pay raises, the teachers’ associations led a state statewide teachers’ strike. The strike successfully raised the teachers’ salaries and moved state legislators to consider the teachers’ pay issue carefully afterwards. However, the pay raise …

Cornerstone Of Union Victory: Officer Partnerships In Joint Operations In The West, Aderian Partain

Master's Theses

The American Civil War included one of the pivotal naval contests of the nineteenth century. A topic of considerable importance is the joint operations on the western waters that brought about a string of crucial victories in the conflict for the Union. The effective cooperation of the naval river fleet and the western armies was a major cornerstone of Union victory. Scholars have written biographies of the more noted admirals and narratives of the flotilla have been detailed. What has not been accomplished is an exploration of the Union officers’ professional partnerships between the Mississippi Squadron commanders and their corresponding …

A Content Analysis Of Section 1983 Litigation Against Reserve Police Officers, Michael Ryan Broadus

Master's Theses

Police studies have well developed a demonstrative framework for detailing risks which generate financially-detrimental civil litigation – particularly regarding 42 U.S.C. §1983. Conversely, though, police studies have given little attention to the often-used but differentially-trained reserve police officer. Primarily replicating the methodologies of Kappeler, Kappeler, and del Carmen (1993) and Ross (2000), this descriptive study sought to fill this void via a manifest content approach to purposively select a sample of Section 1983 cases decided by U.S. District Courts over a 16-year period (2001-2016) to determine: (1) if significant liability was generated by reserve officers, (2) the main basis for …

Sequence Stratigraphy Of Campanian-Maastrichtian Strata In Eastern Alabama, David Simmons

Master's Theses

Eastern Alabama is an area of interest due to the transition from the Gulf Coastal Plain to the Atlantic Coastal Plain. Coastal Plain investigations have been sparse compared to research conducted in the oil rich areas down dip in the Gulf of Mexico. A sequence stratigraphic framework using the T-R cycle methodology of Embry (2002) has been established by integrating surface and subsurface lithologic data with biostratigraphic zonations into Petra ®. High sedimentation from the ancestral Chattahoochee River and lower relative sea-level formed an additional depositional sequence within the Santonian-Campanian aged Blufftown Formation in eastern Alabama. The sequence is approximately …

Coastal Wetland Dynamics Under Sea-Level Rise And Wetland Restoration In The Northern Gulf Of Mexico Using Bayesian Multilevel Models And A Web Tool, Tyler Hardy

Master's Theses

There is currently a lack of modeling framework to predict how relative sea-level rise (SLR), combined with restoration activities, affects landscapes of coastal wetlands with uncertainties accounted for at the entire northern Gulf of Mexico (NGOM). I developed such a modeling framework – Bayesian multi-level models to study the spatial pattern of wetland loss in the NGOM, driven by relative RSLR, vegetation productivity, tidal range, coastal slope, and wave height – all interacting with river-borne sediment availability, indicated by hydrological regimes. These interactions have not been comprehensively investigated before. I further modified this model to assess the efficacy of restoration …

Blazing Worlds, Bethany Kinney

Master's Theses

Blazing Worlds is a collection of short stories exploring themes of understanding, isolation, the world of work, and identity. These stories follow characters who are searching for connections to others, to their environments, to their work, and to themselves. The protagonists of these stories inhabit worlds that are slightly adjacent to reality, worlds cast into a near future, and worlds that operate by the logic of the campy and the fantastic. Through heightened technology, body horror, or blurred metaphysical boundaries, the residents of these blazing worlds pursue knowledge of their place in life and fight to establish and maintain their …

Asic Design Of Rf Energy Harvester Using 0.13um Cmos Technology, Jainish K. Zaveri

Master's Theses

Recent advances in wireless sensor nodes, data acquisition devices, wearable and implantable medical devices have paved way for low power (sub 50uW) devices. These devices generally use small solid state or thin film batteries for power supply which need replacement or need to be removed for charging. RF energy harvesting technology can be used to charge these batteries without the need to remove the battery from the device, thus providing a sustainable power supply. In other cases, a battery can become unnecessary altogether. This enables us to deploy wireless network nodes in places where regular physical access to the nodes …

Metabarcoding Analysis Of Prey Composition Of The Copepod Calanus Finmarchicus In Regions Of The North Atlantic Ocean, Heidi Yeh

Master's Theses

The copepod Calanus finmarchicus occupies a pivotal position in the pelagic food web of the North Atlantic Ocean. Prey choice and predator-prey dynamics at this trophic level can influence energy transfer through the ecosystem. To examine the copepod prey composition and test the hypothesis that C. finmarchicus exhibit spatial variation in diet across four basins of the North Atlantic, this study used metabarcoding analysis (high throughput sequencing of orthologous gene regions) to analyze the gut contents of C. finmarchicus. Zooplankton net samples were collected during a 2013 cruise of the R/V GO Sars in the Norwegian, Icelandic, Irminger, and Labrador …

Evaluation Of Post-Graduate Endodontic Program Clinical Experiences: A Web-Based Survey, Jonathan David Blacher

Master's Theses

Endodontic residency programs vary in exposure to procedures, protocols and equipment across the United States. Available resources for clarifying the clinical experiences of current endodontic residents are lacking. Following Institutional Review Board approval, a survey regarding the clinical experiences of current endodontic residents was electronically distributed to all current endodontic residents that maintained an email address listed in the 2016/2017 AAE Membership Directory. The number of endodontic procedures, techniques employed, and products utilized were evaluated and described. The results of the survey included a 30% completion rate (133/437). The majority of respondents indicated completing between: 150-250 non-surgical root canals (NS-RCT), …

The American Dream(Ers): Undocumented Youth’S (Re)Interpretation Of Social Movement Frames, Kevin Zevallos

Master's Theses

The dreamer narrative and its accompanying frames have become a staple of immigration debates in the United States. Dreamer narratives afford undocumented youth organizations visibility to articulate their socio-political needs. As undocumented youth make claims for legal and social recognition, they utilize dreamer frames that highlight undocumented youth as productive, patriotic, and/or deserving members of U.S. society. Based on 18 semi-structured interviews with undocumented youth and Connecticut state legislators and participant observation of undocumented youth-led rallies, lobbying campaigns and organizational meetings, I examine how undocumented youth organizers react, respond and utilize nationally derived social movement frames in a local context. …
