Interrelationships Between Sensation Seeking And Psychopathy, Casey S. Iwai

Psychology Theses & Dissertations

Psychopathic and sensation seeking traits are often correlated; however, sensation seeking alone is not inherently pathological. This study seeks to investigate possible moderating variables between individuals who are high on sensation seeking but low on measures of psychopathic or antisocial traits. Specifically, a positive family environment is hypothesized to be a moderating variable in the development of psychopathic traits among high sensation seekers. A college student sample assessed for psychopathy, sensation seeking, and family functioning is used to test this hypothesis. Significant relationships between all three constructs were found. Similar to previous data, sensation seeking was found to correlate with …

Organic Copper Binding Ligands And Thiol Compounds Produced By Bacteria And In The Elizabeth River, Virginia, Christina Louise Dryden

OES Theses and Dissertations

This dissertation presents work focusing on copper and organic copper binding ligands in laboratory cultures and the Elizabeth River, Virginia. Laboratory cultures of the marine bacterium Vibrio parahaemolyticus were used to demonstrate the influence of elevated copper concentrations on copper-complexing ligand and thiol production. Copper-complexing ligands similar in binding strength to the strongest natural ligands were detected in V. parahaemolyticus cultures (log K′_CuL = 11.8–13.2). A strong correlation (r² = 0.973) was found between total thiol and copper-complexing ligand concentrations at all copper concentrations examined.

A yearlong seasonal study was undertaken in a heavily polluted estuary to ascertain …

Feasibility Of Mainstream Nitrite Oxidizing Bacteria Out-Selection And Anammox Polishing For Enhanced Nitrogen Removal, Pusker Raj Regmi

Civil & Environmental Engineering Theses & Dissertations

Short-cut nitrogen removal avoids nitrite oxidation to nitrate by nitrite oxidizing bacteria (NOB) and allows a) reduction of formed nitrite to nitrogen gas via heterotrophic denitrification and/or b) oxidation of remaining ammonia with formed nitrite to nitrogen gas via anaerobic ammonia oxidation (anammox). The precondition for achieving shortcut nitrogen removal is suppression of NOB, which is favored by warm and high ammonia strength conditions found in internally generated ammonia-rich waste streams through anaerobic digestion of waste solids referred to as sidestreams or reject water. The discovery of anammox bacteria in the mid-1990s, which are capable of transforming NH₄+ …

Experimental And Computational Analysis Of The Synucleins, Agatha Munyanyi

Theses and Dissertations in Biomedical Sciences

The synuclein proteins α, β and γ which are located in the brain, have been a subject of intense research. Of particular interest is α-synuclein, which is found in misfolded forms in Lewy bodies that are associated with Parkinson's disease. Despite the efforts of researchers across the world, the physiological structure and function of the synucleins remains elusive. In recent years, highly controversial reports by some investigators indicate that in its natural form, α-synuclein exists as a tetramer instead of as an intrinsically unstructured monomer. This dissertation presents results of the experimental and computational analysis of the synucleins. First, we …

Density Functional Theory Modeling Of It-Stacking And Electrophilic Donor-Acceptor Interactions With Application To Therapeutic Targeting Of Zinc-Finger Proteins, Patricia Beall Lutz

Chemistry & Biochemistry Theses & Dissertations

Several viruses, including viruses that cause cancer, contain conserved zinc finger (ZF) proteins that are essential for viral reproduction, making them attractive drug targets for cancer and viral treatment. ZFs are small protein domains that have Zn²⁺ tetrahedrally coordinated to at least 2 Cys and His. They form three classes of ZFs depending on the amino acid ligands, CCHH, CCCH, and CCCC. Zn²⁺ is stable towards redox reactions; however, the Cys thiolates are redox active. Oxidation of the Cys thiolates release Zn²⁺, and the ZF loses its tertiary structure and can no longer bind DNA or …

A Cross-National Analysis Of The Impact Of Conscription On Crime Rates, Nicolette G. Rose

Implications Of Climate Change For Cyanobacteria Over The Western Florida Shelf In The Gulf Of Mexico, Ivy Mara Ozmon

OES Theses and Dissertations

Concentrations of atmospheric CO₂ are expected to double by year 2100 as a result of anthropogenic activities. Under elevated CO₂ conditions, cyanobacteria may reallocate energy from active accumulation and transport of dissolved inorganic carbon (C) required for photosynthesis to other growth processes. Stimulation of cyanobacterial production on the Western Florida Shelf in the Gulf of Mexico (GOM) could lead to improved nutritional status for the toxic, mixotrophic dinoflagellate Karenia brevis that utilizes newly fixed N₂ from co-occurring diazotrophic cyanobacteria and consumes unicellular cyanobacteria via grazing for growth. Culture studies performed by other researchers on the climate induced …

A Comprehensive Evaluation Of C25 Highly Branched Isoprenoid Alkenes Of Marine Diatoms As Proxies For Sea Ice Extent In The Arctic Ocean, Tetiana Muniak

OES Theses and Dissertations

Sea Ice extent is one of the major factors regulating carbon cycling and ecosystem function in the modern Arctic Ocean. It is an essential component of climate models and is crucial for the evaluation of various oceanographic processes that influence a particular region. Yet it is also one of the most difficult attributes of the ocean with respect to our ability for its accurate reconstruction from paleo records. The lack of the detailed records prior to satellite information has encouraged the development of new proxy records for the reconstruction of past

sea ice conditions. In recent years, a new monounsaturated …

The Ecological Impact Of Casitas On Caribbean Spiny Lobster (Panulirus Argus) Populations In The Florida Keys, Fl, (Usa), Benjamin C. Gutzler

Biological Sciences Theses & Dissertations

Casitas are artificial structures placed on the seabed by fishermen to aggregate Caribbean spiny lobsters (Panulirus argus) for ease of capture. Some researchers suggest that they may also enhance lobster populations in shelter-limited environments. Conversely, aggregation of lobsters within casitas may be detrimental to the population if the nutritional condition or mortality of lobsters is poorer in casitas than in natural shelters. Small juvenile lobsters may be at particular risk because their foraging range is smaller and they are more readily preyed upon than larger lobsters. If so, then casitas placed in lobster nurseries may function as "ecological traps"; wherein …

Evaluation Of The Epa Swmm Model To Simulate Low Impact Development Features In An Urban Stormwater Environment, Holly Ann Carpenter

Civil & Environmental Engineering Theses & Dissertations

This research thesis explores the use of the Environmental Protection Agency's (EPA) Stormwater Water Management Model (SWMM) to model an urban watershed with a developed stormwater management system and test the SWMM model's ability to simulate Low Impact Development (LID) features by proposing typical LID features that can be retrofitted to the developed study area. The SWMM model is established with an existing survey of the study area's stormwater management system, and due to the lack of field data for the study area, the model developed in this research thesis is calibrated with the consideration of a published stormwater model …

Screening Out Innovation: The Merits Of Meritless Litigation, Alexander A. Reinert

Articles

Courts and legislatures often conflate merit-less and frivolous cases when balancing the desire to keep courthouse doors open to novel or unlikely claims against the concern that entertaining ultimately unsuccessful litigation will prove too costly for courts and defendants. Recently, significant procedural and substantive barriers to civil litigation have been informed by judicial and legislative assumptions about the costs of entertaining merit-less and frivolous litigation. The prevailing wisdom is that eliminating merit-less and frivolous claims as early in a case’s trajectory as possible will focus scarce resources on the truly meritorious cases, thereby ensuring that available remedies are properly distributed …

The Experiences Of School Counselors With Court Involvement Related To Child Custody, Crystal E. Hatton

Counseling & Human Services Theses & Dissertations

Professional school counselors are often confronted with a myriad of legal and ethical challenges when working with students and their families. While school counselors are discouraged from becoming involved in child custody matters, many are unable to avoid the process for a variety of reasons. This qualitative phenomenological research inquiry explored professional school counselors' experiences with court involvement in child custody matters and sought to understand how such experiences may have affected how they perceive their role in assisting children and families who are undergoing divorce, separation, or child custody disputes. A series of semi-structured interview questions and a written …

Student-Directed Blended Learning With Facebook Groups And Streaming Media: Media In Asia At Furman University, Tami Blumenfield

Asian Studies Publications

Furman University prizes itself on being an engaged learning, liberal arts institution with extensive faculty-student interaction. 96% of students live on campus, leading some to question whether reducing face-to-face instructional time makes any sense pedagogically. Coming from a different institution that encouraged faculty to create hybrid courses, and seeing the creativity and freedom that offered, I wanted to experiment with the format in this new institutional environment. Would it still be effective? What adaptations would be necessary, and how would students react to this different course format?

In Fall 2013, I taught a carefully designed blended learning course that met …

Modulating Notochordal Differentiation Of Human Induced Pluripotent Stem Cells Using Natural Nucleus Pulposus Tissue Matrix, Yongxing Liu, M. N. Rahaman, B. Sonny Bal

Materials Science and Engineering Faculty Research & Creative Works

Human induced pluripotent stem cells (hiPSCs) can differentiate into notochordal cell (NC)-like cells when cultured in the presence of natural porcine nucleus pulposus (NP) tissue matrix. The method promises massive production of high-quality, functional cells to treat degenerative intervertebral discs (IVDs). Based on our previous work, we further examined the effect of cell-NP matrix contact and culture medium on the differentiation, and further assessed the functional differentiation ability of the generated NC-like. The study showed that direct contact between hiPSCs and NP matrix can promote the differentiation yield, whilst both the contact and non-contact cultures can generate functional NC-like cells. …
