Use Of A Dynamic Balance System To Quantify Postural Steadiness And Stability Of Individuals With Lower-Limb Amputation: A Pilot Study, M. Barbara Silver-Thorn Phd, Joel Kempfer, Alyssa J. Schnorenberg, Brooke Slavens

Biomedical Engineering Faculty Research and Publications

Introduction Despite rehabilitation and gait training, the gait of individuals with lower-limb amputation is often asymmetric and falls and/or fear of falling are common. Clinical assessments of balance and stability include the Berg BalanceScale and the Dynamic Gait Index. Biomechanical assessments, conducted largely in research laboratories, are more objective, quantitative, and may provide greater resolution. These biomechanical measures include postural sway during both unilateral and bilateral standing tasks and the dynamic postural response to applied or volitional perturbations. The objective of this study was to investigate the utility of a dynamic balance system, a relatively new clinical tool incorporating dual …

Real Time Evaluation Of Tissue Optical Properties During Thermal Ablation Of Ex Vivo Liver Tissues, Vivek K. Nagarajan, Venkateswara R. Gogineni, Sarah B. White, Bing Yu

Biomedical Engineering Faculty Research and Publications

Complete ablation of liver tumors is vital for minimizing the risk of local tumor recurrence. Accurately identifying the hallmarks of tissue necrosis during thermal ablative therapies may significantly increase the efficacy of ablation, while minimizing unnecessary damage to the surrounding normal tissues or critical structures. Light propagation in biological tissues is sensitive to the tissue microstructure and chromophore concentrations. In our previous studies, we found that the wavelength (λ) averaged liver tissue absorption coefficient μ_a and reduced scattering coefficient μ_s’ change significantly upon heating which may be used for assessment of tissue damage during thermal …

Affective Risk Perception In Automotive Environments, Dane Atkins

Dissertations and Theses @ UNI

Traversing the automotive environment exposes drivers to a risk of property damage, injury, and death. This risk varies across the road network. This research questions whether drivers are capable of accurately perceiving their own exposure to risk in this environment. Analysis begins with an assessment of risk exposure at roadway intersections (as measured in terms of crash frequency, severity, and mixed-weighting methods). This assessment provides risk indices for a cross-section of road intersections across an urban Iowa community. These indices are then used in the development of an experimental visual cognition survey used to record risk perceptions of roadway sites …

Health Sciences Program Student Theses, Dissertations and Capstones

Affordable Care Act (ACA) was passed and implemented to expand insurance coverage, reduce health care cost, and improve the quality of care. The purpose of this dissertation study was to investigate whether the ACA insurance expansion correlates with the number of visits made to emergency departments (EDs). The quasi-experimental design interrupted time series was utilized in the analysis. The ED visits were compared using MANOVA to determine the relationship between ED visits and ACA and canonical correlation analysis to assess the strength of the relationship and the extent to which independent variables could predict the dependent variable. The hypothesis was …

Paper-Based Analytical Device For Determination Of Triglycerides, Yolthida Kantapa

Chulalongkorn University Theses and Dissertations (Chula ETD)

In this work, a paper-based analytical device (PAD) together with enzymatic reactions was developed for determination of triglycerides using colorimetric detection. The method was based on the enzymatic reactions between triglycerides and enzymes (lipase, glycerol kinase and glycerol-3-phosphate oxidase). Hydrogen peroxide which was generated from the enzymatic reactions is reduced by chromogenic substrates which were 3-methyl-2-benzothiazolinone hydrazone (MBTH) and 3-(dimethylamino)benzoic acid (DMAB) in the presence of peroxidase to produce an indamine dye. The blue color intensity of indamine dye is directly proportional to triglycerides concentration. For quantitative analysis, the interfering effect of ascorbic acid in real samples was eliminated using …

Positively Charged Particles From Amphiphilic Chitosan For Plasmid Dna Delivery, Tinnakorn Phuangkaew

Chulalongkorn University Theses and Dissertations (Chula ETD)

Amphiphilic chitosan derivatives have been well regarded as potential non-viral vectors for gene delivery. Their hydrophobic entities could promote cell permeability whereas their hydrophilic entities especially those carrying positive charges can interact with the negatively charged phosphate groups of DNA. Here in this research, a series of amphiphilic chitosan derivatives were synthesized. Linear hydrocarbon of two different chain length: hexyl (C6) and dodecyl (C12) were substituted at amino groups of chitosan via reductive alkylation with hexanal and dodecanal and yielded two hydrophobized chitosan derivatiives, hexyl chitosan (HCS) and dodecyl chitosan (DCS), respectively. Phthaloyl chitosan (PhCS) was also prepared as another …

Image Super-Resolution Technique Using Deep Inception Based Residual Networks, Wazir Muhammad

Chulalongkorn University Theses and Dissertations (Chula ETD)

Recently, deep Convolutional Neural Networks (CNN) have achieved exceptional performance over the past few years, in the area of image processing and computer vision task, especially on single image super-resolution (SISR). It is an immensely challenging task and has multiple practical applications, such as medical image processing, satellite imaging, facial image enhancement, and compressed image improvement. However, the majority of the existing image super-resolution CNN-based methods have been developed by stacking an innumerable number of layers and blindly increasing the size of the network architecture. Conversely, this leads to an increase in the model sizes and higher computational complexities. Furthermore, …

Of Brutal Murder And Transcendental Sovereignty: The Meaning Of Vested Private Rights, Adam J. Macleod

Scholarly Articles

The idea of vested private rights is divisive; it divides those who practice law from those who teach and think about law. On one side of the divide, practicing lawyers act as though (at least some) rights exist and exert binding obligations upon private persons and government officials, such that once vested the rights cannot be taken away or retrospectively altered.1 Lawyers convey estates in property, negotiate contracts, and write and send demand letters on the supposition that they are specifying and vindicating rights, which are rights not as a result of a judgment by a court in a subsequent …

Hyperfunding: Regulating Financial Innovations, Seth C. Oranburg

Scholarly Articles

Innovations in corporate finance are driven by frustrations with present regulations and fueled by the internet and social media. Hyperfunding is one such example: Tesla paved the way for an electric vehicle revolution by preselling hundreds of thousands of its Model 3 EV direct to consumers. Unwary consumers may not have realized that they were underwriting Tesla's bold strategy to transform multiple product markets. Risks were not disclosed. Rewards proved illusory. Investors would have been entitled to disclosures and colorable claims of fraud when Tesla missed milestones and deadlines. But consumers can only get their $1000 deposit back, without interest, …

Effects Of Traffic Incidents On Adjacent Facilities And Alternative Re-Routing Strategies, Alican Karaer

UNF Graduate Theses and Dissertations

This study presents an analysis of detour operations as a concept of congestion management. Since a large portion of traffic delay emanates from traffic incidents, the goal of the study was to alleviate incident-induced impacts on freeways by diverting congested traffic on to adjacent roadway facilities. To balance the demand between freeway and arterial systems, optimization was required through Integrated Corridor Management (ICM). This thesis examines the justification and optimization of dynamic traffic routing strategies.

Previous studies have justified detour operations based solely on traffic simulation results. This study quantifies the impacts from freeway incidents on a parallel arterial roadway …

The Role Of Wave Self-Similarity In Nearshore Wave Spectra, Morgan M. Smith

UNF Graduate Theses and Dissertations

Nonlinear wave-wave interactions and wave breaking contribute to nearshore wave energy dissipation. These factors can be analyzed by the principles of wave self-similarity. The equilibrium range can be shown in wind-driven wave spectra that exist in the form ( ) and However, the appropriate methods used to determine this loss of energy are controversial. This study examines an approach that reinvestigates the self-similarity principles. Wave spectra with lower peak periods are dominated by nonlinear wave-wave interactions which produce a scaling in shallow water. This thesis investigates the relative role of spectral similarity in different conditions in the nearshore region of …

Evaluation Of Traffic Incident Timeline To Quantify The Performance Of Incident Management Strategies, Henrick Joseph Haule

UNF Graduate Theses and Dissertations

Transportation agencies are introducing new strategies and techniques that will improve traffic incident management. Apart from other indicators, agencies measure the performance of the strategies by evaluating the incidents timeline. An effective strategy has to reduce the length of the incident timeline. An incident timeline comprises various stages in the incident management procedure, starting when the incident was detected, and ending when there is the recovery of normal traffic conditions. This thesis addresses three issues that are related to the traffic incident timeline and the incident management strategies.

First, co-location of responding agencies has not been investigated as other incident …

Get Legitimate: Achievements Promote Recovery From Addiction Via Non-Addict Identity, Daniel Crutchfield

UNF Graduate Theses and Dissertations

Abstract

Despite decades of research, over 400 million people around the globe suffer from substance abuse and only 10% to 43% maintain abstinence after treatment. Social support, spirituality, self-regulation, and locus of control have all been examined for their efficacy and relationship with successful abstinence outcomes. Conceptually, educational/vocational achievement is believed to contribute to reforming an identity divorced from the previous lifestyle of active addiction. Educational and Vocational achievements as proxies for non-addict identity have only been investigated sporadically. The present study seeks to establish a quantitative link between successful long-term recovery and these types of goal-oriented achievements. A survey …

Particle Filters For State Estimation Of Confined Aquifers, Graeme Field

UNF Graduate Theses and Dissertations

Mathematical models are used in engineering and the sciences to estimate properties of systems of interest, increasing our understanding of the surrounding world and driving technological innovation. Unfortunately, as the systems of interest grow in complexity, so to do the models necessary to accurately describe them. Analytic solutions for problems with such models are provably intractable, motivating the use of approximate yet still accurate estimation techniques. Particle filtering methods have emerged as a popular tool in the presence of such models, spreading from its origins in signal processing to a diverse set of fields throughout engineering and the sciences including …

"Contra Haereticos Accingantur": The Union Of Crusading And Anti-Heresy Propaganda, Bryan E. Peterson

UNF Graduate Theses and Dissertations

This study assesses the intersection of crusading and heresy repression in the late twelfth and early thirteenth centuries. The event that encapsulates this intersection was the Albigensian Crusade, a two-decades long conflict that befell the south of France, or Occitania. The papacy, aligned with northern lords and other willing Christians, took up arms to defend the Church from the Cathar heresy’s corrupting influence. This conflict marked a new development in Christian acts of violence. While the Church had crusaded against many different enemies—even branding some as heretics—before 1209, the Church had never called a crusade for the explicit purpose of …

Associations Between Parenting, Neurobiological Variables, And Adolescent And Young Adult Risk-Taking, Sarah Meghan Mcclanahan

UNF Graduate Theses and Dissertations

Evidence suggests that adolescence and young adulthood is a transitional stage whereby unique contextual factors may increase the likelihood for certain individuals to engage in risk-taking compared to their peers. In addition to influential environmental aspects (i.e. parenting, societal affiliations, peer influence) an adolescent’s and young adult’s underdeveloped cognitive control system is unable to successfully inhibit early maturing tendencies such as sensation seeking and reward sensitivity. However, previous research indicates that certain parental mechanisms may serve as protective/promotive agents for stabilizing this neurobiological imbalance. Therefore, the focus of the current research was to examine how parenting behaviors and styles moderate …

Impressions Of A Female Political Candidate Based On Political Party Affiliation, Candice J. Veilleux

UNF Graduate Theses and Dissertations

There is a gender gap in United States politics; men are over represented, and prioritize issues/policies differently compared with women. Stereotypes may be associated depending on group memberships. Stereotypes of men (competent) are consistent and stereotypes of women (warm) are inconsistent with politicians (competent). I examined stereotypes of major/non-major political parties, and how party affiliation affects whether stereotypes about men/male politicians/women/female politicians predict female politicians’ traits. Stereotype valence ascribed to political parties is important because people vote for a positively viewed party/representative. I assessed the strength and valence of stereotypes associated with political parties, and found major parties were viewed …

Opioid Use Disorder: The Ugly Return And Treatment Effectiveness Of Heroin Use, Antwana L. Drayton

UNF Graduate Theses and Dissertations

Relationships among demographic, socioeconomic and person factors and Opioid Use Disorder diagnosis, treatment, and recidivism were explored. Data from a sample of 4,860 adults with substance use difficulties were analyzed. A program evaluation was conducted on Gateway Community Services to explore the use of Medication Assisted Treatments (MATs) and Psychosocial (PS) treatments to address Opioid Use Disorder. Using archival data, a chi-square analysis and independent sample t-test was performed. The results expressed that a relationship among race, type of substance use diagnosis, and treatment type and recidivism rate was found. While White/Non-Hispanics adults were more likely to use heroin than …

"Who Will Teach The Poor Little Ones To Say Their Prayers?" Catholics, Protestant, And Black Education In Reconstruction Era St. Augustine, Florida., Justin Stuart

UNF Graduate Theses and Dissertations

In 1968, the doors of St. Benedict the Moor’s school in St. Augustine, Florida, closed after nearly seventy years of service to members of the city’s African American community. But St. Benedict’s school represented a long tradition of black Catholic education in St. Augustine. Under Spanish rule, a boy’s school existed that offered equal education to blacks and whites. Florida’s possession by the United States complicated matters as territorial and state laws ended black education in the city, and the Catholic Church chose to side with the South over the issue of slavery in the United States. With the town’s …

Establishing Relationships Among Environmental Stressors, Host Immune Status, And Wasting Disease Susceptibility In The Dominant Seagrass Species Thalassia Testudinum, Paige Joy Duffin

UNF Graduate Theses and Dissertations

A growing body of evidence supports the observation that marine disease outbreaks, especially those caused by opportunistic pathogens, are increasing in frequency and severity. One genus of such pathogens, Labyrinthula, has been identified as the causative agent of seagrass wasting disease, an epidemic that has historically plagued seagrass beds around the world. It is suspected that pathogenicity is intimately linked to the ability of the host to initiate defense responses, but a lack of compelling evidence prevents any meaningful application of preliminary observations. This body of work investigated the roles of host genotype, host immune status, and environmental stressors …

A Consideration Of Mason’S Ethical Framework: The Importance Of Papa Factors In The 21st Century: A Seven-Year Study, Katharine Creevey Brown

UNF Graduate Theses and Dissertations

Richard Mason proposed a social framework for addressing the major ethical issues of the information age in his pivotal 1986 article “Four Ethical Issues of the Information Age.” In 2006, Alan Peslak validated the framework by measuring the current attitudes of students, IT professionals, and university faculty and staff toward the four key issues proposed by Mason: privacy, accuracy, property, and accessibility (referred to as PAPA). This study continues this inquiry into the seven-year period after Peslak’s research. Previously collected data was analyzed for 312 university computing majors taking a senior-level ethics course where Mason was taught and discussed. Demographic …
