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 …

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 …

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.

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 …

Grounded in relational dialectical theory, transcripts from interviews of five non-residential stepfamily couples were analyzed using qualitative content analysis to search for and identify autonomy-connection and openness-closedness dialectical tensions and coping strategies utilized by the participants. These relational dialectical tensions were illustrated in every interview. Tensions were present not only between the relationship partners, but also in regard to the non-residential children. Participants utilized a variety of coping strategies to deal with the relationship tensions experienced in their marriage within …

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 …

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 …

Facilitating The Generalization Of Social Skills With Bibliotherapy And Positive Peer Reporting, Angelina C. Krieger

Theses and Dissertations

Social competence is needed for interaction among peers, teachers, and families in order for children to be successful in school. Children enter school with various levels of social competence. Social skills training is an effective method for building social skills; however, many programs fail to generalize these skills across settings and time. This study investigated the effects of a social skills training intervention for first and second grade students with emotional and behavioral problems. The intervention blended direct instruction, role-plays, and children's literature, with peers supporting both the acquisition and generalization of the social skills through positive peer reporting (PPR) …

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), …

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 …

Genetic Variations In Three Interacting Single Nucleotide Polymorphisms And The Risk Of Preterm Birth In Black Families, Margaret Steinbach

Open Access Dissertations

Preterm birth, defined as birth prior to 37 completed weeks gestation, is a serious health concern. Despite advances in health care screening and interventions, the rate of preterm birth in the United States has risen more than 30 percent since 1981. In 2006, Menon and associates reported the first multilocus genetic interaction in three single nucleotide polymorphisms predictive of spontaneous preterm birth in a population of White mothers. A gene association study using a case-control design was conducted to determine whether the results of the Menon study were also true for Black women and their infants. The case group included …
