First, among many privacy-preserving methodologies, as a group of popular techniques for achieving a balance between data utility and information privacy, a class of data perturbation methods add a noise signal, following a statistical distribution, to an original numerical matrix. With the help …

A Network Path Advising Service, Xiongqi Wu

Theses and Dissertations--Computer Science

A common feature of emerging future Internet architectures is the ability for applications to select the path, or paths, their packets take between a source and destination. Unlike the current Internet architecture where routing protocols find a single (best) path between a source and destination, future Internet routing protocols will present applications with a set of paths and allow them to select the most appropriate path. Although this enables applications to be actively involved in the selection of the paths their packets travel, the huge number of potential paths and the need to know the current network conditions of each …

Establishment Of Biotrophy By The Maize Anthracnose Pathogen Colletotrichum Graminicola: Use Of Bioinformatics And Transcriptomics To Address The Potential Roles Of Secretion, Stress Response, And Secreted Proteins, Ester Alvarenga Santos Buiate

Theses and Dissertations--Plant Pathology

Colletotrichum graminicola is a hemibiotrophic pathogen of maize that causes anthracnose leaf and stalk rot diseases. The pathogen penetrates the host and initially establishes an intracellular biotrophic infection, in which the hyphae are separated from the living host cell by a membrane that is elaborated by the host, apparently in response to pathogen signals. A nonpathogenic mutant (MT) of C. graminicola was generated that germinates and penetrates the host normally, but is incapable of establishing a normal biotrophic infection. The mutated gene is Cpr1, conserved in eukaryotes and predicted to encode a component of the signal peptidase complex. How …

What Do Auditors Promise Their Governmental Audit Clients? What Do Governmental Audit Clients Want? Audit Proposal Evidence From Governmental Audit Procurement Processes, Yu-Tzu Chang

Theses and Dissertations--Accountancy

This dissertation, consisting of two studies, analyzes a dataset of audit proposals to investigate auditors’ impression management strategies and audit procurement quality in the public sector. Text based analytic methods are employed to examine the content of audit proposals, which were submitted for government audit engagements in fifteen states.

The first study investigates auditors' marketing language and hypothesizes that CPA firms will project a cooperative, non-independent image in audit proposals to impress potential clients. The results suggest that CPA firms, especially larger ones, project a persona of a cooperative and trustworthy service provider than to present themselves as independent auditors. …

Exploring Bisexual-Identified Persons Experiences Of Belonging, David Pascale-Hague

Theses and Dissertations--Educational, School, and Counseling Psychology

Belonging is a basic and fundamental human need (Baumeister, & Leary, 1995) that is associated with psychosocial health (Cohen, 2004). Unfortunately, community belonging is a challenge for those with a bisexual identity. Binegativity, minority stress, and the invisibility of bisexual-identities may interfere with attempts to develop a sense of community belonging (Bradford, 2004). Little systematic research has examined bisexual-identified people’s perceptions and experiences of belonging to a community. This project addressed the question, “What are bisexual individuals’ experiences of community belonging/social exclusion?” Semi-structured interviews were conducted with a sample of 12 bisexual-identified persons. Interview transcripts were analyzed using a constructivist …

Each participant provided demographic information and then answered a series of questions, using a hedonic rating scale or by composing a written response. Participants also provided qualitative data about what influenced their preference between the test and control. The experiment confirmed the hypothesis was correct: Millennials prefer waffle fries over potato wedges. It also confirms that Millennials prefer a unique, crunchy, crispy, and decreased potato filled product. Millennial consumers reported significant preference of the …

Surface Functionalized Magnetic Nanoparticles For Cancer Therapy Applications, Robert J. Wydra

Theses and Dissertations--Chemical and Materials Engineering

Despite recent advances, cancer remains the second leading cause of deaths in the United States. Magnetic nanoparticles have found various applications in cancer research as drug delivery platforms, enhanced contrast agents for improved diagnostic imaging, and the delivery of thermal energy as standalone therapy. Iron oxide nanoparticles absorb the energy from an alternating magnetic field and convert it into heat through Brownian and Neel relaxations. To better utilize magnetic nanoparticles for cancer therapy, surface functionalization is essential for such factors as decreasing cytotoxicity of healthy tissue, extending circulation time, specific targeting of cancer cells, and manage the controlled delivery of …

Noncontact Diffuse Correlation Tomography Of Breast Tumor, Lian He

Theses and Dissertations--Biomedical Engineering

Since aggressive cancers are frequently hypermetabolic with angiogenic vessels, quantification of blood flow (BF) can be vital for cancer diagnosis. Our laboratory has developed a noncontact diffuse correlation tomography (ncDCT) system for 3-D imaging of BF distribution in deep tissues (up to centimeters). The ncDCT system employs two sets of optical lenses to project source and detector fibers respectively onto the tissue surface, and applies finite element framework to model light transportation in complex tissue geometries. This thesis reports our first step to adapt the ncDCT system for 3-D imaging of BF contrasts in human breast tumors. A commercial 3-D …

The Universality Of Medicaid At Fifty, Nicole Huberfeld

Law Faculty Scholarly Articles

This essay explores how the law of Medicaid after fifty years creates a meaningful principle of universalism by shifting from fragmentation and exclusivity to universality and inclusivity. The universality principle provides a new trajectory for all of American health care, one that is not based on individual qualities that are unrelated to medical care but rather grounded in non-judgmental principles of unification and equalization (if not outright solidarity). To that end, this Essay first will study the legislative reformation that led to universality and its quantifiable effects. The Essay then will assess and evaluate Medicaid’s new universality across four dimensions, …

Leadership Training For A Diverse World: A Study Of The Effectiveness Of Three Interventions With Fraternity And Sorority Leaders, Kirsten A. Gonzalez

Theses and Dissertations--Educational, School, and Counseling Psychology

Lesbian and gay college students face heterosexist and homophobic attitudes and behaviors from their heterosexual peers (Burn, 2000; Fine, 2011; Franklin, 2000; Rankin, 2003; Silverschanz, Cortina, Konik, & Magley, 2008; Woodford, Howell, Silverschanz, & Yu, 2012; & Yost & Gilmore, 2011). Greek fraternity and sorority organizations can contribute to and influence the heterosexist and homophobic climate on college campuses. Greek organizations offer leadership opportunities, community engagement, and a sense of belonging, but these organizations can also perpetuate a climate of hostility and rejection of lesbian and gay peers (Case, 1996; Case, Hesp, & Eberly, 2005; DeSantis, 2007; Rankin et al., …

Its compact size and light weight will increase mobility, allowing investigators …

Sediment Organic Carbon Fate And Transport In A Fluviokarst Watershed In The Bluegrass Region, Admin Husic

Theses and Dissertations--Civil Engineering

Mature karst topography is well recognized within the hydrology and geology communities to include subterranean fluid pathways that act as turbulent conduits conveying fluid from surface stream sinks called swallets to sources called springs. However, we find that little knowledge has been reported with regards to the transport and fate of terrestrially-derived sediment organic carbon (SOC) within karst watersheds. This study investigated the hypothesis that karst pathways could act as biologically active conveyors of SOC that temporarily store sediment, turnover carbon at higher rates than otherwise considered, and recharge depleted SOC back to the surface stream within the fluvial system. …

Computational Fluid Dynamics (Cfd) Modeling And Validation Of Dust Capture By A Novel Flooded Bed Dust Scrubber Incorporated Into A Longwall Shearer Operating In A Us Coal Seam, Ashish R. Kumar

Theses and Dissertations--Mining Engineering

Dust is a detrimental, but unavoidable, consequence of any mining process. It is particularly problematic in underground coal mining, where respirable coal dust poses the potential health risk of coal workers’ pneumoconiosis (CWP). Float dust, if not adequately diluted with rock dust, also creates the potential for a dust explosion initiated by a methane ignition. Furthermore, recently promulgated dust regulations for lowering a miner’s exposure to respirable coal dust will soon call for dramatic improvements in dust suppression and capture.

Computational fluid dynamics (CFD) results are presented for a research project with the primary goal of applying a flooded-bed dust …

Examining The Neuroprotective Properties Of 3-Dimethoxybenzylidene-Anabasine (Dmxb-A) In A Third Trimester Chronic Ethanol Exposure Model In Rats, Logan J. Fields

Theses and Dissertations--Psychology

Excitotoxicity caused by ethanol (ETOH) withdrawal (EWD) is highly detrimental to the developing brain. Targeting this excitotoxicity has been shown to be a promising approach for improving outcome following developmental ETOH exposure. Activation of nicotinic acetylcholine receptors (nAChR), in the central nervous system can be protective against EWD. We examined the ability of DMXB-A, a α₇ nAChR agonist, to reduce neurotoxicity caused by EWD in the hippocampus. To test this, an organotypic hippocampal slice culture was used. Slices were exposed to ETOH (100mM) or control medium. After 10 days, the slices were treated with DMXB-A (1, 3, or 10uM) …

An Optical Sprayer Nozzle Flow Rate Sensor, Joseph S. Dvorak, Luke E. Bryant

Biosystems and Agricultural Engineering Faculty Publications

Ensuring proper flow rates from each nozzle on an agricultural sprayer has become even more important as advances continue to be made in precision application technology. In this article, we describe the structure and testing of a sensor technology based on optical cross-correlation to determine the flow rate of individual sprayer nozzles. An advantage of this technology is that it does not require that impellers or other components be placed in the flow, which could cause plugging. The only moving part in the entire system is a solenoid used to inject a tracer dye. The objective of this study was …

Participatory And Holistic Approaches With Grassland Farmers And Development Of Policies, Alain Peeters

IGC Proceedings (1977-2023)

The world is changing rapidly. Grassland farmers and ruminant livestock breeders will have to adapt to these changing environmental, social and economic conditions. Research can help them at the condition that linear ‘top-down’ technology transfer methods are abandoned for the benefit of participatory and holistic approaches. These approaches classified in the generic term of ‘Farming System Research’ consider farmers as real research partners, and they merge farmer’s and scientist’s ideas with those of other stakeholder types. They combine scientist’s and farmer’s knowledge for creating fast innovations, easily adopted by farmers since farmers themselves contribute to their design and their development. …

Recycling Of Lignite Coal Fly Ash By Its Conversion Into Zeolites, Silviya Boycheva, Denitza Zgureva, Annie Shoumkova

Coal Combustion and Gasification Products Journal Archive

The present study emphasized the conversion of fly ash from lignite coals into zeolites by a double-stage fusion-hydrothermal synthesis. The raw and the converted fly ashes were characterized with respect to their morphology, composition, and crystallinity. The effects of process parameters such as fusion temperature, concentration of the alkaline activator, and the duration of the hydrothermal incubation on the zeolitization process were studied. The experimental results indicate that the fusion temperature does not influence the process mechanism in the range 550–850uC, but it has an acceleration effect. The elevation of the sodium hydroxide/fly ash ratio from 1.6 to 2.0 enhances …
