Spectroscopic And Spectro-Astrometric Analysis Of T Tauri Stars, Logan Ryan Brown

Dissertations

To understand our own solar origins, we must investigate the composition of the protoplanetary disk from which the solar system formed. To infer this, we study analogs to the early solar system called T Tauri stars. These objects are low-mass, pre-main sequence stars surrounded by circumstellar disks of material from which planets are believed to form. We present high-resolution, near-infrared spectroscopic data for the T Tauri stars DR Tau and AA Tau using NIRSPEC at the Keck II telescope. For DR Tau, a spectro-astrometric analysis was performed, obtaining sub-seeing spatial information on water emission. Alongside a disk model, we constrained …

I identified pathogens in rodent blood samples by …

Synthetic Ion Channels: A New Class Of Membrane Disruptor And Efflux Pump Inhibitor For The Recovery Of Antibiotic Potency, Mohit Bharatkumar Patel

Dissertations

Antibiotic resistance has become a world-wide health care crisis. In 2013 there were 50,000 deaths in U.S. and EU, associated with hospital acquired bacterial infections. This problem is exacerbated by the lack of new antibiotics in development. Here, we report that synthetic amphiphiles represent a new class of adjuvants that rescue antibiotic potency against multidrug resistant bacteria. Hydraphiles are amphiphiles, designed and synthesized in Gokel lab, that show many of the same properties as protein ion channels. Hydraphiles were previously shown to have antimicrobial activity against Escherichia coli, Bacillus subtilis and Saccharomyces cerevisiae. Here, we report that hydraphiles recover the …

Endogenous Small Interfering Rna: Insights Into Esirna Biogenesis And Their Precursors, Andrew White Harrington

Dissertations

Rarely in research is the path to an answer straightforward. Initial questions lead to more questions, many times doubling back to allow for greater insight into the original question. For example, discovery of interactions between previously unrelated pathways can lead to breakthroughs with regard to understanding of gene regulation. One such novel interaction and the subsequent discoveries this interaction spurred are discussed herein. Transposons, or “Jumping Genes” are mobile genetic elements found throughout all three major domains of life. Transposons comprise 44% of the human genome and possess the ability to move within the genome. This ability makes them an …

Implementation Of Sleep Assessment Questionnaire In College Health And Counseling Visits: A Quality Improvement Pilot, Sarah Ruth Jackson

Dissertations

Sleep deprivation or sub-optimal sleep hygiene in college students has profound implications. Decreased cognitive performance, increased depression or mood concerns, higher rates of usage of alcohol or marijuana to compensate for poor sleep are all interconnected. The American College Health Survey (2011) results indicated that students do not receive support or education on the importance of sleep habits from their schools or medical providers. This DNP project explored two areas of interest. The first was a change in patient interview protocol as a quality improvement project in UMSL University Health, Wellness, Counseling & Disability Access Services (UHWC&DAS). The second area …

Synthesis Of Optimization And Simulation For Multi-Period Supply Chain Planning With Consideration Of Risks, Liang Xu

Dissertations

Solutions to deterministic optimizing models for supply chains can be very sensitive to the formulation of the objective function and the choice of planning horizon. We illustrate how multi-period optimizing models may be counterproductive if traditional accounting of revenue and costs is performed and planning occurs with too short a planning horizon. We propose a “value added” complement to traditional financial accounting that allows planning to occur with shorter horizons than previously thought necessary. This dissertation presents a simulation model with an embedded optimizer that can help organizations develop strategies that minimize expected costs or maximize expected contributions to profit …

Online writing consultation continues to advance from mere asynchronous email systems to more technologically rich synchronous venues. Technologies, such as chat rooms and video conferencing software, to even more immersive and interactive virtual environments, have created complex and rewarding spaces for writing consultations to take place. However, most professional conversation, training, and research for online writing consultation focuses on two aspects of online writing consultation—technological knowledge, often fixated on learning to use a technology to teach, and pedagogical knowledge, knowledge about writing and tutoring practices, which are often based in traditional face-to-face tutoring processes. This study looks at how writing …

Impact Of A Growth Mindset Intervention On Academic Performance Of Students At Two Urban High Schools, Lisa Brougham

Dissertations

Urban high school students have greater challenges with respect to retention and graduation rates than their non-urban peers (Farrington et al., 2012). Many academic initiatives have attempted to resolve the problems of retention and poor academic performance with little sustained success. For this study, the empirical literature was reviewed to identify a remedy for poor academic performance that may be implemented by school counselors. Focusing on non-cognitive skills, specifically developing a growth mindset, has shown promising results (Aronson, Fried, & Good, 2002; Blackwell, Trzesniewski, & Dweck, 2007; Yeager & Dweck, 2012). The underlying theoretical framework for this study is Dweck’s …
