Remote Sensing To Detect The Movement Of Wheat Curl Mites Through The Spatial Spread Of Virus Symptoms, And Identification Of Thrips As Predators Of Wheat Curl Mites, Abby R. Stilwell

Department of Entomology: Dissertations, Theses, and Student Research

The wheat curl mite (WCM), Aceria tosichella Keifer, transmits three viruses to winter wheat: wheat streak mosaic virus, High Plains virus, and Triticum mosaic virus. This virus complex causes yellowing of the foliage and stunting of plants. WCMs disperse by wind, and an increased understanding of mite movement and subsequent virus spread is necessary in determining the risk of serious virus infections in winter wheat. These risk parameters will help growers make better decisions regarding WCM management. The objectives of this study were to evaluate the capabilities of remote sensing to identify virus infected plants and to establish the potential …

Development Of The Mask Scentometer, A Comparison Of Ambient Odor Assessment Methods, And Their Application In Ground Truthing Atmospheric Dispersion Models, Christopher G. Henry

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

This dissertation is organized as four stand-alone papers. Paper No. 1 describes the development of the Mask Scentometer and reports dilution ratios measured during use by twelve different people. Dilution ratios at the Mask Scentometer’s five dilution-to-threshold (D/T) settings were found to be 0.35, 1, 2, 4.5 and 18. In Paper No.’s 2 and 4, ambient odor assessment methods were compared in both controlled laboratory conditions and in the field. Laboratory analysis of ambient air samples using dynamic triangular forced-choice olfactometry (DTFCO) did not correlate well with any of the ambient odor assessment methods. Average intensity-predicted D/T was roughly five …

Nest And Brood Survival And Habitat Selection Of Ring-Necked Pheasants And Greater Prairie-Chickens In Nebraska, Ty Matthews

School of Natural Resources: Dissertations, Theses, and Student Research

Ring-Necked Pheasant (Phasianus colchicus) and Greater Prairie-chicken (Tympanuchus cupido pinnatus) populations have declined in the Midwest since the 1960’s. Research has suggested decreased nest and brood survival are the major causes of this decline due to the lack of suitable habitat. Habitat degradation has been attributed to the shift to larger crop fields, lower diversity of crops, and more intensive pesticide and herbicide use. A primary goal of the Conservation Reserve Program (CRP) is to mitigate the loss of wildlife habitat. Early research found that CRP increased the amount of suitable nesting and brood rearing cover …

Background

High density genetic maps of plants have, nearly without exception, made use of marker datasets containing missing or questionable genotype calls derived from a variety of genic and non-genic or anonymous markers, and been presented as a single linear order of genetic loci for each linkage group. The consequences of missing or erroneous data include falsely separated markers, expansion of cM distances and incorrect marker order. These imperfections are amplified in consensus maps and problematic when fine resolution is critical including comparative genome analyses and map-based cloning. Here we provide a new paradigm, a high-density consensus genetic map of …

Patterning-Induced Surface Chirality And Modulation Of Director Twist In A Nematic Cell, Yoonseuk Choi, Timothy J. Atherton, Sameh Ferjani, Rolfe G. Petschek, Charles Rosenblatt

Faculty Scholarship

A substrate coated with a polyimide alignment layer is scribed bidirectionally with the stylus of an atomic force microscope to create an easy axis for liquid-crystal orientation. The resulting noncentrosymmetric topography breaks two-dimensional inversion symmetry and results in a spatial amplitude modulation of an imposed twisted nematic state. This is observed optically as spatially periodic light and dark stripes. When the alignment layer is scribed unidirectionally the centrosymmetric topography maintains inversion symmetry, and no stripes are observed. The appearance of the twist modulation is consistent with a chiral term in the free energy.

Revisiting The Personal Influence Model As An Ethical Standard In Public Relations Theory And Practice, Rita Somfai

Theses and Dissertations

This thesis attempts to better understand the importance and application of the personal influence model in relationship building between organizations and public decision makers. The personal influence model was added by Sriramesh and Grunig (1992) as a potential fifth model to Grunig and Hunt's (1984) four models of public relations practice (as cited by Grunig in Heath, 2007); however, this essential relationship building approach has not been examined in the public relations literature as it could have been. Scholarly research since the addition of the personal influence model has mostly occurred in Asia and India. Studies on the topic have …

Constructing Data Curation Profiles, Michael Witt, Jacob R. Carlson, Melissa Cragin, D. Scott Brandt

Libraries Research Publications

This paper presents a brief literature review and then introduces the methods, design, and construction of the Data Curation Profile, an instrument that can be used to provide detailed information on particular data forms that might be curated by an academic library. These data forms are presented in the context of the related sub-disciplinary research area, and they provide the flow of the research process from which these data are generated. The profiles also represent the needs for data curation from the perspective of the data producers, using their own language. As such, they support the exploration of data curation …

The International Trade Commission: Potential Bias, Hold-Up, And The Need For Reform, William Dolan

Duke Law & Technology Review

The International Trade Commission (ITC) is an alternate venue for holders of U.S. patents to pursue litigation against infringing products produced abroad and imported to the United States. Because the ITC may only grant injunctive relief, it has awarded injunctions in situations where there may have been better and more efficient remedies to the infringement available through litigation in federal district court. The increased likelihood of injunctive relief bolsters the position of patent holders against a wide range of producers in royalty negotiations and can harm the end consumers through a process known as "patent hold-up." There are currently sweeping …

Safety Rituals: How Women Cope With The Fear Of Sexual Violence, Luciana C. Silva, David W. Wright

The Qualitative Report

In this study we focus on how women's fear of sexual violence shapes their views on sexual assault and influences their use of safety strategies as well as how those safety strategies may restrict their use of time and space. Semi-structured interviews were conducted with 5 participants who also journaled for one week on the topic of sexual violence. Data were analyzed through an inductive analysis approach. These women think about sexual violence as a widespread problem that affects them disproportionately more than it affects men; they engage in precautionary behaviors in a ritualistic manner; and their fear of sexual …

An Adaptive Bayesian Approach To Dose-Response Modeling, Thomas J. Leininger

Theses and Dissertations

Clinical drug trials are costly and time-consuming. Bayesian methods alleviate the inefficiencies in the testing process while providing user-friendly probabilistic inference and predictions from the sampled posterior distributions, saving resources, time, and money. We propose a dynamic linear model to estimate the mean response at each dose level, borrowing strength across dose levels. Our model permits nonmonotonicity of the dose-response relationship, facilitating precise modeling of a wider array of dose-response relationships (including the possibility of toxicity). In addition, we incorporate an adaptive approach to the design of the clinical trial, which allows for interim decisions and assignment to doses based …

Transcription Analysis Of The Chlorovirus Paramecium Bursaria Chlorella Virus-1, Giane M. Yanai

School of Biological Sciences: Dissertations, Theses, and Student Research

Paramecium bursaria chlorella virus (PBCV-1), a member of the family Phycodnaviridae, is a large dsDNA, plaque-forming virus that infects the unicellular green alga Chlorella NC64A. The 331 kb PBCV-1 genome is predicted to encode 365 proteins and 11 tRNAs. To follow global transcription during PBCV-1 replication, a microarray containing 50-mer probes to the PBCV-1 365 protein-encoding genes (CDS) was constructed. Competitive hybridization experiments were conducted employing cDNAs from poly A-containing RNAs obtained from cells at seven time points after virus infection. The results led to the following conclusions: i) the PBCV-1 replication cycle is temporally programmed and regulated; ii) 360 …

Wim Based Live Load Model For Bridge Reliability, Marek Kozikowski

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Development of a valid live load model is essential for assessment of serviceability and safety of highway bridges. The current HL-93 load model is based on the Ontario truck measurements performed in 1975. Since that time truck loads have changed significantly. Therefore, the goal of this study is to analyze 2005-2007 Weigh-In-Motion (WIM) data and develop a new statistical live load model.

The analyzed WIM data includes 47,000,000 records obtained from different states. A special program was developed to calculate the maximum live load effect. Comparison of the old and new truck data showed that on average Ontario trucks are …

Introduction: Obesity is one of the most important medical problems in the U.S. and is considered to be an epidemic with over 30% of the population being obese. Obesity is associated with increased risk of hypertension, diabetes, cardiovascular diseases, certain cancers and a shorter life expectancy. Recent studies have shown that higher BMI levels are also significantly associated with several lifetime mental disorders such as major depressive disorder, anxiety disorders as well as panic attacks and panic disorders. Purpose: The purpose of this study was to quantify the extent to which higher BMI increased the likelihood of Depression, Anxiety Disorder …

Enhanced Environmental Detection Of Uranyl Compounds Based On Luminescence Characterization, Jean Nelson

Theses and Dissertations

Uranium (U) contamination can be introduced to the environment as a result of mining and manufacturing activities related to nuclear power, detonation of U-containing munitions (DoD), or nuclear weapons production/processing (DOE facilities). In oxidizing environments such as surface soils, U predominantly exists as U(VI), which is highly water soluble and very mobile in soils. U(VI) compounds typically contain the UO22+ group (uranyl compounds). The uniquely structured and long-lived green luminescence (fluorescence) of the uranyl ion (under UV radiation) has been studied and remained a strong topic of interest for two centuries. The presented research is distinct in its objective of …

Intimate Partner Violence And Pregnancy: Data From The Chicago Women's Health Risk Study, Anne Zehner

Theses and Dissertations

Background: Intimate partner violence (IPV) during pregnancy increases the risks of adverse outcomes for both mothers and their unborn children, including maternal and fetal death. However, more research is needed to determine if IPV increases in frequency or severity during pregnancy and to determine what the risk factors are for IPV during pregnancy. Objectives: To use data from the Chicago Women’s Health Risk Study to determine (1) if abuse is more prevalent during the pregnancy period, 2) if abuse during the pregnancy period increases in frequency or severity, 3) if pregnant women who are abused are at increased risk for …

Experimental And Numerical Investigation On Pyroelectric Energy Scavenging, Jingsi Xie

Theses and Dissertations

Pyroelectric energy scavenging is the process of converting wasted energy from a system to power another one, based on the pyroelectric effect of piezoelectric materials. Pyroelectrically generated power is a function of the surface of material, the pyroelectric coefficient, and the temporal temperature gradient. In the current project, a simple model is developed to predict the power generation based on the temporal change in temperature of material. In addition, a model is validated with experimental measurements from several piezoelectric materials. It is shown that energy generation can be enhanced by using piezoelectric materials with significantly higher pyroelectric coefficients such as …

Zooplankton Abundance, Community Composition And Grazing In The James River Estuary (Virginia, Usa), Laura E. Barry

Theses and Dissertations

This study examined the extent to which zooplankton in the James River Estuary (Virginia, USA) exploit the available algal-food resources. Zooplankton abundance, community composition and grazing rates were assessed at three locations which included a site with high algal production (near the VCU Rice Center) and two sites where algal production was lower. Grazing rates were measured by determining the rate of phytoplankton decline (as chlorophyll a) during 48-hour incubation experiments in the presence and absence of zooplankton. Significant differences in zooplankton abundance were observed among the three sites, with the greatest average zooplankton density (434 ± 69 ind/L) occurring …

Mindfulness, Health, Well-Being, And Patient Care Of Oncologists, Amanda Kracen

Theses and Dissertations

Demands on physicians in the workplace are growing, as are the occupational and psychosocial stressors they encounter. However, there is scant research regarding physicians, their patient care, and strategies that enhance their well-being. Mindfulness, the ability to be present in the moment, is increasingly being encouraged among healthcare workers for personal benefits and possible positive effects for patients. Thus, the present study examined (a) the health, well-being, and patient care practices of oncologists, (b) the relationship between oncologists’ mindfulness and health indicators (general health and sleep problems) with three outcomes (satisfaction with life [SWL], job satisfaction, and suboptimal patient care), …
