Comparative Analysis Of Healthcare Expenditure In The United States And Canada, Chris N. Anazia

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Total healthcare expenditures and expenditures as a percentage of GDP have been substantially higher in the U.S. than in Canada between 1975 – 2008. Hospitalcare, physician and clinical services, and drug prescription expenditures have been the principal components contributing to growth in healthcare expenditures in the U.S. compared to Canada. This study reviews the literature on increasing healthcare costs and establishes some comparative and descriptive analysis for high healthcare costs in the two countries during this time period. The study also analyses and compares the growth of healthcare costs.

Nanotherapies For Treating Prostate Cancer, Michael Danquah

Theses and Dissertations (ETD)

Current prostate cancer treatment remains ineffective primarily due to ineffectual therapeutic strategies and numerous tumor-associated physiological barriers which hinder efficacy of anticancer agents. Therefore, the focus of this study was to investigate a new combination therapy approach for treating prostate cancer and develop polymeric nanocarriers to facilitate anticancer drug and nucleic acid delivery.

It was hypothesized that simultaneously targeting androgen-androgen receptor (AR) and X-linked inhibitor of apoptosis protein (XIAP) signaling pathways would be effective in treating prostate cancer. The effect of bicalutamide (antiandrogen) and embelin (XIAP inhibitor) on the growth of prostate cancer cells in vitro and in vivo was …

Leveraging Whole Life Cycle Costs When Utilising Building Information Modelling Technologies, Barry Mcauley, Dernot Kehily

Conference papers

Building Information Modelling (BIM) is now being increasingly used as a technology tool to assist design professions in conceiving, designing, constructing and operating the built environment in many countries. The BIM model provides design professions with the framework to perform exercises in design, programming, cost and value management and concept energy analysis, in order to achieve the most economical and sustainable building solution. The BIM model though sophisticated is not extensively used to provide estimation software with the data requirements for Life Cycle Costing (LCC), such as, escalation of future expenditure and/or present value costs, discount rates and study periods. …

Agent-Based Virtual Humans In Co-Space: An Evaluative Study, Yilin Kang, Ah Hwee Tan, Fiona Fui-Hoon Nah

Business and Information Technology Faculty Research & Creative Works

Co-Space refers to interactive virtual environment modelled after the real world in terms of look-and-feel, functionalities and services. We have developed a 3D virtual world named Nan yang Technological University (NTU) Co-Space populated with virtual human characters. Three key requirements of realistic virtual humans in the virtual world have been identified, namely (1) autonomy: Agents can function on their own, (2) interactivity: Agents can interact naturally with players, and (3) personality: Agents can exhibit human traits and characteristics. Working towards these challenges, we propose a brain-inspired agent architecture that integrates goal-directed autonomy, natural language interaction and human-like personality. We conducted …

Effect Of Nitrogen On Safflower Physiology And Productivity, Sj Mohamed, Aj Jellings, Mp Fuller

School of Biological and Marine Sciences

Safflower (Carthamus tinctorius L.) is an oil-crop suitable for semi-arid agriculture, but its physiological response to agronomic inputs has yet to be fully evaluated. The effect of fertiliser on the physiology and production of safflower grown in pots filled with standard grade perlite inside a semi-controlled glass house was studied. Plants were initially irrigated with 20-100 ml standard hydroponic solution and then one month after germination plants were irrigated using 50-200 ml complete Hoagland’s solution, supplemented with one of eight levels of nitrogen (0, 25, 50, 75, 100, 125, 150, 175 kg N ha-1) in the form of ammonium nitrate. …

Incentive Based Approach To Find Selfish Nodes In Mobile P2p Networks, Hemanth Meka, Sanjay K. Madria, Mark Linderman

Computer Science Faculty Research & Creative Works

In a Mobile P2P (M-P2P) network, selfish nodes can drop packets to affect the efficiency of the whole network. Therefore, we propose a simple and efficient mechanism using virtual currency to identify selfish nodes in the network. Each node issues a receipt to its broker to prove that it has provided a forwarding service. based on receipts received each broker provides well-behaved nodes some virtual currency whereas selfish nodes are punished on dropping packets to make the network more efficient. When compared to other known approaches, our scheme provides real-time detection of selfish nodes and does not require/assume the presence …

Exploring Compile Time Caching Of Explicit Queries In Programming Codes, Venkata Krishna Suhas Nerella, Sanjay Madria, Thomas Weigert

Computer Science Faculty Research & Creative Works

Object oriented programming languages raised the level of abstraction by incorporating first class query constructs explicitly in the program codes. These query constructs allow programmers to express operations over collections as object queries and also provide optimal query execution utilizing query optimization strategies from domain of databases. However, when a query is repeated in the program, it is executed afresh. This paper presents an approach to reduce the run time execution of programs involving explicit queries by caching the results of repeated queries and incrementally maintaining the cached results. We propose determination of cache entries at compile time by performing …

Switchgrass Potential On Reclaimed Surface Mines For Biofuel Production In West Virginia, Michael A. Marra

Graduate Theses, Dissertations, and Problem Reports (ETD)

The high cost and environmental risks associated with non-renewable energy sources has caused an increased interest in, and development of renewable biofuels. Switchgrass (Panicum virgatum L.), a warm season perennial grass, has been investigated as a source of biofuel feedstock due to its high biomass production on marginal soils, its tolerance of harsh growing conditions, and its ability to provide habitat for wildlife and soil conservation cover. West Virginia contains vast expanses of reclaimed surface mine lands and could potentially benefit from the production of switchgrass as a biofuel feedstock. Furthermore, switchgrass production could satisfy Surface Mining Reclamation and Control …

Graduate Theses, Dissertations, and Problem Reports (ETD)

The objective of this dissertation is to design decentralized controllers to enhance the transient stability of power systems. Due to the nonlinearities and complexities of the system, nonlinear control design techniques are required to improve its dynamic performance. In this dissertation a synergetic control technique is being proposed to design supplementary controller that is added to the exciter of the generation unit of the system. Although this method has been previously applied to a Single Infinite Machine Bus (SMIB) system with high degree of success, it has not been employed to systems with multi machine. Also, the method has good …

Impulsivity And Suicidal Ideation Or Attempt In Younger And Older Adults, Elizabeth C. Price

Graduate Theses, Dissertations, and Problem Reports (ETD)

Rates of suicidal behaviors vary over the lifespan, but little research has focused on developmental aspects of suicidal behaviors and associated risk factors. Previous studies suggest that young people who attempt or die by suicide are likely to be generally impulsive. 108 community-dwelling older adults age 60 and older and 498 undergraduate students ages 18-30 completed the Center for Epidemiological Studies -- Depression Scale, the Barratt Impulsivity Scale, and the Suicidal Behaviors Scale -- Revised. The hypothesis was that the relation between impulsivity and suicidal ideation or attempt, in the context of depressive symptoms, would be stronger in younger adults …

This thesis work examines similar reservoirs at a depth of around 5 km resembling the geology of West Virginia, USA. The temperature gradients used are in accordance with the SMU study.;In order to …

Near Boundary Turbulence Characteristics Among Stream Restorations Of Varying Intensity, Sean M. Abel

Graduate Theses, Dissertations, and Problem Reports (ETD)

Stream restoration is estimated to be a multi-billion dollar industry and includes techniques such as planting vegetation, modifying channel form, and installing in-stream structures. These techniques potentially alter the velocity field and flow complexity. The specific objective of this research was to characterize near-boundary flow within the three restored reaches of varying intensities located in the Stream Research, Education, and Management (StREAM) Laboratory at Virginia Tech. Three restoration techniques were applied in 2009-10 to consecutive reaches of Stroubles Creek: 1) cattle restriction only (0.5 km); 2) cattle restriction, banks reshaped to 3:1 slope and re-vegetated (0.6 km); and, 3) designed …

The Influence Of Self-Reported Family Functioning On Depression Symptom Severity And Psychological Well-Being In Treatment-Seeking Older Adults, Patricia M. Bamonti

Graduate Theses, Dissertations, and Problem Reports (ETD)

Among treatment-seeking older adults, positive social ties are related to depression outcomes prospectively. Less is known regarding the role of negative social ties in relation to depression and well-being outcomes among patients in treatment. The current study adds to this literature through the cross-sectional and prospective examination of patients' appraisal of family members perceived criticism in relation to self-reported depressive symptom severity and psychological well-being In addition, potential moderators of these relations were examined, including personality variables (Neuroticism and Conscientiousness), cognitive functioning, and living status. adults 60 years of age and older newly (< 1 month after intake session) receiving treatment for depressive or anxious symptomatology at a university-affiliated outpatient clinic as part of an on-going study that assessed depression and decision-making in late life. Results demonstrated that individuals with increased perceived criticism also had greater depressive symptom severity, at least measured at one point in time. Perceived criticism failed to predict change in depression symptom severity in the prospective analyses. Similarly, perceived criticism was associated with lower psychological well-being in the cross-sectional analyses; however, perceived criticism failed to predict change in psychological well-being in prospective analyses. No significant interactions were found with perceived criticism, suggesting at least in the current study, personality variables, cognitive functioning, and living status did not qualify the relation between perceived criticism and depression symptom severity or change in depression symptom severity over time. EI was not significantly associated with depression symptom severity and psychological well-being cross-sectionally and prospectively, after controlling for perceived criticism and perceived social support from family. Implications, limitations, and future directions are discussed.

Public Land Management Values: A Delphi Study Of Austrian And Pacific Northwest United States Recreation Resource Managers, Jessie Meybin

Graduate Theses, Dissertations, and Problem Reports (ETD)

There is a continuing global increase in recreational visitor use of public land. This rise in visitation can be a good thing if a proactive management plan utilizing strong methodology to anticipate impacts to an area and sustain its natural and social resources is in place. Although a wide spectrum of issues is presented to each management, few of the concepts are new to any of the administrators. With increasing duties, newly emerging concerns, and decreasing time, there is little room or patience for error concerning the implementation of any management derivatives or techniques. If the existing research on all …

Psychosocial Concerns In Pediatric Obstetric Brachial Plexus Injury Patients, Janelle M. Mentrikoski

Graduate Theses, Dissertations, and Problem Reports (ETD)

Obstetric brachial plexus injuries (OBPI) occur during childbirth when the child's shoulder blade gets stuck on the mother's pubic bone, resulting in damage to nerves in the child's shoulder. Due to the possible visible nature (e.g., injured arm may be shorter than the non-injured arm) and mobility limitations (e.g., difficulties in raising the injured arm to brush one's teeth) associated with these injuries, youth with OBPI may experience psychosocial difficulties. However, little research has examined the psychosocial functioning in this population. The current study sought to investigate possible predictors of social functioning and self-concept in youth with OBPI. This study …

Riparian Ecological Community Assessment With An Emphasis On Wood Turtles (Glyptemys Insculpta) In The Cacapon River Watershed, West Virginia, Kathryn R. P. Mccoard

Graduate Theses, Dissertations, and Problem Reports (ETD)

Riparian zones serve to maintain high water quality, low water temperatures, and structural complexity in aquatic and terrestrial environments, among other beneficial services. Riparian buffers provide habitat and corridors linking forest patches for terrestrial wildlife. High riparian vegetative structure and complexity attract a high diversity of wildlife, including birds, herpetofauna, and small mammals. Devegetated riparian zones, often a result of developmental and agricultural practices, lose their beneficial functions and require restorative actions to regain them. The Cacapon River watershed in West Virginia is agriculturally-dominated with many areas of riparian zone degradation. A section of the Cacapon River was selected for …

A Comparison Of Testosterone With Prostate Specific Antigen And Prostatic Acid Phosphatase For The Serodiagnosis Of Prostate Cancer In Adult Males, Annie Chu

Honors Theses

Prostate cancer is the second most common cause of death from cancer in men. The American Cancer Society has estimated that there were 240,890 newly diagnosed cases in 2011 and 33,720 deaths from prostate cancer. Diagnosis of this disease has traditionally been done by measuring prostate specific antigen (PSA) levels through sero-chemical testing. The purpose of this study is to compare serum testosterone levels to PSA levels and Prostatic Acid Phosphatase (PAP) levels in the search for new and more accurate technology. This study shows that testosterone was not efficient in correctly diagnosing those with prostate cancer. It had a …

South Mississippi High School Seniors’ Perceptions Of Civic Duties And Responsibilities, Chelsea L. Lewis

Honors Theses

Former United States Representative Lee Hamilton once explained what it takes to be a citizen of the United Stated. He stated, “Citizenship requires both knowledge about government and the ability to be involved in governance. It means knowing how to identify and inform oneself about issues, explore and evaluate possible solutions, and then act to resolve problems. It demands that you know how to interact respectfully with others. And it asks that you accept responsibility for meeting your community’s and the nation’s challenges.” (Hamilton, 1) This quote comes from a well-known civics program used in American high schools today called …

EIA is a prevalent disorder affecting collegiate athletes. Non-pharmacological evidence-based practices can be used by EIA athletes to minimize asthma symptoms. Modifications to the athlete’s breathing techniques, diet, and warm-up protocol can be implemented to reduce asthma symptoms. To determine if athletes at USM are using these practices, a survey questioning their education and implementation of these practices was administered to all the USM athletes. Of the 331 …

Parenting Styles, Peer Pressure, And The Formation Of Antisocial Behavior, Erinisha L. Johnson

Honors Theses

The current study examined the relationship between antisocial behavior, negative parenting, and peer pressure. It was predicted that peer pressure and negative parenting would be positively correlated with antisocial behavior, but that negative parenting would be more statistically significant. There were 177 male and female college students who completed the Subtypes of Antisocial Behavior questionnaire, the Measurement of Parenting Style, the Peer Pressure and Popularity questionnaire, and a short demographics survey. Results indicated that negative parenting and peer pressure were both related to antisocial behavior (p< .001). However, the final hypothesis was rejected because the results indicated that peer pressure (p < .001) and not negative parenting (p<.05), showed to be more statistically significant. It may be suggested that peer pressure may overpower parenting, after a certain age.

English Identity In The Writings Of John Milton, Hannah E. Ryan

Honors Theses

John Milton is an essential writer to the English canon. Understanding his life and thought is necessary to understanding his corpus. This thesis will examine Milton’s nationalism in several major and minor poems as well as in some of Milton’s prose.

Effect Of Msa On Antibiotic Resistance And Allelic Replacement Of Pkor1 In Staphylococcus Aureus, Jordan M. Towne

Honors Theses

Staphylococcus aureus is an important human pathogen that causes hospital and community-acquired infections (52). These infections are difficult to treat due to resistance to a wide range of antibiotics and spread of antibiotic-resistant strains (13, 52). S. aureus causes infection by regulation of accessory genes encoding for expression of factors contributing to virulence (9, 11, 12, 29, 34, 43, 45), including severe infection, biofilm formation, autolysis, and antibiotic resistance (4, 5, 7, 27, 56). Actually, extracellular DNA and nutrient release during autolysis has been shown to contribute to the ability of bacteria to form and maintain a biofilm as well …

The Homeless Perception Of Services, Alexander K. Pickle

Honors Theses

This study, recognizing a lack of academic research into the homeless population’s needs, approaches the problem of needs assessment of the homeless through the context of customer service. The literature points to a discontentment with the classic shelter model, and potential positives in newer, emerging alternatives. Using the “Gap Model of Service Quality”, qualitative interviews were structured and scheduled with the homeless individuals in Hattiesburg, Mississippi. The study encountered many obstacles, including lack of participation. Due to these complications, it could not come to any meaningful conclusions; however, there are multiple avenues for further research that developed through the process.
