Adolescent Initiation And Maintenance: An Analysis Of The Roles Of Self-Efficacy, Sensation Seeking, Parents, And Peers, Benjamin Bullock

Perspectives

Alcohol use among adolescents is a public health concern. Research of the predictors of adolescent alcohol initiation and use are necessary to better combat the negative impacts associated with alcohol use by youth. Due to social influences, adolescents develop a sense of self-efficacy and sensation seeking, which can guide them to get involved in early alcohol use. Both parents and peers have a great deal of authority to push one to have certain beliefs about drinking alcohol. The goal of this literature review is to better understand how the personality characteristics of self-efficacy and sensation seeking influence alcohol initiation and …

The Role Of String Similarity Metrics In Ontology Alignment, Michelle Cheatham, Pascal Hitzler

Computer Science and Engineering Faculty Publications

Tim Berners-Lee originally envisioned a much different world wide web than the one we have today - one that computers as well as humans could search for the information they need [3]. There are currently a wide variety of research efforts towards achieving this goal, one of which is ontology alignment.

Intracellular Delivery Of Nanoparticles And Dnas By Ir9 Cell-Penetrating Peptides, Betty Revon Liu, Ji-Sing Liou, Yue-Wern Huang, Robert Aronstam, Han-Jung Lee

Biological Sciences Faculty Research & Creative Works

Cell-penetrating peptides (CPPs) comprised of basic amino residues are able to cross cytoplasmic membranes and are able to deliver biologically active molecules inside cells. However, CPP/cargo entrapment in endosome limits biomedical utility as cargoes are destroyed in the acidic environment. In this study, we demonstrate protein transduction of a novel CPP comprised of an INF7 fusion peptide and nona-arginine (designated IR9). IR9 noncovalently interacts with quantum dots (QDs) and DNAs to form stable IR9/QD and IR9/DNA complexes which are capable of entering human A549 cells. Zeta-potentials were a better predictor of transduction efficiency than gel shift analysis, emphasizing the importance …

Factors Influencing Nest Site Selection By Wood Turtles (Glyptemys Insculpta) In An Altered Forest Landscape, Ellery Ruther

Theses & Honors Papers

There have been many studies concerning wood turtle (Glyptemys insculpta) nest site selection, including studies that evaluate nest site conditions when stream sand banks are not available. However, because of the unique landscape at our study site (high gradient, first order streams) and rapidly diminishing wood turtle populations in Virginia, I am evaluating wood turtle nest site selection. Nine physiographic and vegetative characteristics from nest, positive, negative-one and negative-two control locations were evaluated using binomial generalized linear models and then best fit models were chosen using Akaike's Information Criterion (AIC). It was found that in lieu of typical stream …

Improving Bioactivity And The Anti-Bacterial Properties Of Two-Solution Bone Cement Containing Cross-Linked Polymethylmethacrylate (Pmma) Nanospheres (Η-Tsbc), Shailly Jariwala

Biomedical and Chemical Engineering - Dissertations

The high viscosity standard two-solution bone cements (STSBC) developed in our laboratory exhibits several advantages over other commercial powder-liquid cement formulations. However, the high monomer concentration, viscosity, and exothermal temperature are considered a major limitation to the use of this material. Modified two-solution cements containing cross-linked polymethylmethacrylate (PMMA) nanospheres (η-TSBC), as part of the polymer phase, were fabricated as the first step for optimization of cement viscosity for application of the material in the treatment of vertebral compression fractures using vertebroplasty (VP) and kyphoplasty (KP). The η-TSBC exhibited reduced viscosity, lower polymerization exotherm, and residual monomer in comparison to STSBC. …

Jailbreakers, Villains, And Vampires: Representations Of Criminality In Early-Victorian Popular Texts, Elizabeth Fay Stearns

English - Dissertations

In Jailbreakers, Villains, and Vampires: Representations of Criminality in Early-Victorian Popular Texts, I analyze moments of discursive dissonance that emerge through the juxtaposition of early-Victorian theories of criminality and representations of criminals in popular culture. In the 1830s and 1840s in England, methods for managing criminals underwent a series of revisions that corresponded to shifts in prevailing theories about the nature and course of criminal behavior. Assumptions that criminality was volitional, or that it originated in an individual's deficient self-discipline, gradually shifted into perceptions that criminality was pathological, and that malefactors were naturally brutish and incorrigible. Predominant conceptions of …

A Springtime Source Of Toxic Pseudo-Nitzschia Cells On Razor Clam Beaches In The Pacific Northwest, Barbara Hickey, Vera Trainer, P. Kosro, Nicolaus Adams, Thomas Connolly, Nancy Kachel, Susan Geier

Faculty Publications

Concentrations of domoic acid (DA) above the regulatory limit in Washington coast razor clams are usually higher on northern beaches from summer to fall. Recent field studies have confirmed that the primary source of toxic Pseudo-nitzschia (PN) cells in those seasons is a semi-retentive topographically trapped seasonal eddy located offshore and north of the clamming beaches. Another semi-retentive coastal feature, Heceta Bank, that has been shown to support toxic PN cells in summer, is located south of Washington’s clamming beaches. In this paper we present evidence to demonstrate that Heceta Bank, although not a likely source of toxic cells to …

Behavioral, Biochemical, And Molecular Indices Of Stress Are Enhanced In Female Versus Male Rats Experiencing Nicotine Withdrawal, Laura O'Dell

Selected Works Temporary Series

Stress is a major factor that promotes tobacco use and relapse during withdrawal. Although women are more vulnerable to tobacco use than men, the manner in which stress contributes to tobacco use in women versus men is unclear.Thus, the goal of this study was to compare behavioral and biological indices of stress in male and female rats during nicotine withdrawal. Since the effects of nicotine withdrawal are age-dependent, this study also included adolescent rats. An initial study was conducted to provide comparable nicotine doses across age and sex during nicotine exposure and withdrawal. Rats received sham surgery or an osmotic …

Actants, Agents, And Assemblages: Delivery And Writing In An Age Of New Media, Steven Holmes

All Dissertations

This dissertation redefines the rhetorical canon of delivery by drawing on interdisciplinary theories of technology and materiality, including hardware and software studies, assemblage theory, and actor-network theory. Rhetorical theorists and composition scholars have correctly equated the technological medium with delivery, but also have focused exclusively on the circulation of symbolic forces rather than the persuasive agency of technology itself, thus eliding the affordances and constraints posed by technological actors at the non-symbolic levels of hardware, software, protocol, and algorithms. I establish a historical precedent in classical theorists such as Demosthenes, Cicero, and Quintilian that acknowledges their understanding of the role …

Overcoming Barriers To Teaching Action-Based Environmental Education: A Multiple Case Study Of Teachers In The Public School Classroom, Terry Rachael Adams

Masters Theses & Specialist Projects

As the human population increases, it becomes increasingly more important for society to understand the impact of humans on the environment. Preserving fixed resources by engaging in sustainable practices is necessary to ensure those resources are available for future generations. Since the early 1960s, policy makers and educators alike have sought to ensure that students graduate environmentally literate. Previous research has identified a multitude of barriers that limit classroom teacher’s ability to integrate environmental education into their curriculum. The purpose of this study was to investigate how teachers overcome those barriers that restrict the integration of action based environmental education …

Using Optimal Control Theory To Optimize The Use Of Oxygen Therapy In Chronic Wound Healing, Donna Lynn Daulton

Masters Theses & Specialist Projects

Approximately 2 to 3 million people in the United States suffer from chronic wounds, which are defined as wounds that do not heal in 30 days time; an estimated $25 billion per year is spent on their treatment in the United States. In our work, we focused on treating chronic wounds with bacterial infections using hyperbaric and topical oxygen therapies.

We used a mathematical model describing the interaction between bacteria, neutrophils and oxygen. Optimal control theory was then employed to study oxygen treatment strategies with the mathematical model. Existence of a solution was shown for both therapies. Uniqueness was also …

Synthesis Of Rhenium And Manganese Pyridazoal Complexes, Jesse Evans

Masters Theses & Specialist Projects

Pyridazines are a heterocyclic aromatic compound containing a characteristic N-N bond that are utilized in many fields, including medicine and electronics. It is this latter field that Dr. Snyder's research group is focused upon. Organometallic compounds are a better conducting material than the current inorganic compounds used in electronics due to better conductance of electricity, lower production cost, and the ability to be formed into thin films. With this in mind, Dr. Snyder's research group has set out to synthesize organometallic compounds for this purpose. Following procedures set forth by Snyder etc, and altered to form an off-metal route, we …

Hybrid Methods For Feature Selection, Iunniang Cheng

Masters Theses & Specialist Projects

Feature selection is one of the important data preprocessing steps in data mining. The feature selection problem involves finding a feature subset such that a classification model built only with this subset would have better predictive accuracy than model built with a complete set of features. In this study, we propose two hybrid methods for feature selection. The best features are selected through either the hybrid methods or existing feature selection methods. Next, the reduced dataset is used to build classification models using five classifiers. The classification accuracy was evaluated in terms of the area under the Receiver Operating Characteristic …

Influence Of Transplanter Modification And Previous Crop On The Production Of No-Till Dark Tobacco, William Frazier Penick

Masters Theses & Specialist Projects

Dark tobacco (Nicotiana tabacum L.) has historically been produced using
conventional tillage practices. Soil is cultivated multiple times throughout a growing season leading to an increased incidence of soil erosion. No-till systems have been growing in popularity with the advent of new technology that has enabled the practice to be performed effectively and efficiently. With the recent expansion of no-till practices throughout the agricultural community, many crops have had success in producing comparable yields while reducing input costs and saving soil resources. For this experiment, a traditional tobacco transplanter was modified for use in a no-till environment. All modifications were …

When God Dies: Deconversion From Theism As Analogous To The Experience Of Death, William David Simpson

Masters Theses & Specialist Projects

In this thesis, I explore the psychological and experiential aspects of the shift from a supernatural theistic worldview (specifically born-again Christianity) to a
philosophically naturalistic and atheistic worldview in the context of the religious
landscape in the U.S. I posit that certain features of this transition, which is known as "deconversion,” can be thought of as potentially analogous, both psychologically and subjectively, to the experience of another's death as an objective environmental change. I provide anthropological and psychological evidence that believers often experience the God of born-again Christianity as an independently existing and active agent in the world. The similarities …

Reactions Of Platinum(Ii) Compounds With Selenium Containing Amino Acids, Stephanie Robey

Masters Theses & Specialist Projects

Platinum(II) anticancer medications essentially react with DNA forming kinks in
the double helix of DNA and causing apoptosis. It has also been noted that these
anticancer medications react with methionine and cysteine in the body. With the new discoveries of selenium containing amino acids including selenomethionine and selenocysteine, new research is ongoing to see what types of products can be formed from these amino acids. Our research reacts [Pt(Met-S,N)Cl₂] ²⁺ with selenomethionine to determine what types of products are produced. Monochelates including [Pt(SeMet-Se,N)Cl₂] ²⁺ have formed two isomers, …

Intrinsic And Extrinsic Motivation: Abraham Lincoln As An Adult Learner, Warren Greer

Masters Theses & Specialist Projects

Over the last two decades, research has identified factors that foster versus undermine human motivation and well being with important implications for learning and performance. Much of the research is concerned with intrinsic versus extrinsic motivation and autonomous versus non-autonomous learning environments. The data suggests that learning and performance are often significantly enhanced in autonomy-supportive environments that foster intrinsic motivational perspectives. This study examines the lived experience of Abraham Lincoln in the context of his adult learning motivation, forming a qualitative narrative around his adult educational experiences. It was hypothesized that Abraham Lincoln benefited from learning experiences with high levels …

Mice Lacking Pten In Osteoblasts Have Improved Intramembranous And Late Endochondral Fracture Healing, Travis A. Burgers, Martin F. Hoffmann, Caitlyn J. Collins, Juraj Zahatnansky, Martin A. Alvarado, Michael R. Morris, Debra L. Sletsema, James J. Mason, Clifford B. Jones, Heidi L. Ploeg, Bart O. Williams

Mechanical Engineering Faculty Publications

The failure of an osseous fracture to heal (development of a non-union) is a common and debilitating clinical problem. Mice lacking the tumor suppressor Pten in osteoblasts have dramatic and progressive increases in bone volume and density throughout life. Since fracture healing is a recapitulation of bone development, we investigated the process of fracture healing in mice lacking Pten in osteoblasts (Ocn-cretg/+; Ptenflox/flox). Mid-diaphyseal femoral fractures induced in wild-type and Ocn-cretg/+; Ptenflox/flox mice were studied via micro-computed tomography (mCT) scans, biomechanical testing, histological and histomorphometric analysis, and protein expression analysis. Ocn-cretg/+; Ptenflox/flox mice had significantly stiffer and stronger intact bones …

Effect Of Coconut Oil On Ulcerative Colitis In The Mouse Model, Pranav Chandra Alok

Masters Theses & Specialist Projects

Ulcerative colitis (UC) is a chronic disease of the colon or large intestine that causes inflammation and ulceration of the inner lining of the colon and rectum. In patients with ulcerative colitis, the body’s immune system overreacts and the body mistakes food, bacteria or other internal materials in the colon for an invading substance. The immune system attacks the material, thus irritating the colon. Limited knowledge of inflammatory conditions coupled with a narrow range of therapeutic options necessitates investigating the role of natural products. This study describes the effect of natural coconut oil on chemically-induced acute and chronic disease in …
