A brief Multiple Stimulus Without Replacement (MSWO) of videos of toys was used to teach a selection response by systematically fading the participants' access to toys during the preference assessment. Once the selection response was successfully taught with the toys, it was assessed with videos of social interactions. A progressive ratio (PR) schedule and concurrent operant reinforcer assessment were then conducted to determine the reinforcing effectiveness of the highest and lowest preferred social interactions from a brief MSWO for each of the participants. The selection response was successfully taught to both participants and mixed results were found from both reinforcer assessments for both participants."--Page ii.

High resolutions of 3D quantitative and qualitative data can represent such phenomena as objects or fields. The data can be grouped to reveal representations of contiguous regions of spatial and thematic homogeneity. My thesis is concerned with finding groups of 3D points with similar locations, spatial relationships, and thematic values of spectral reflectance. To accomplish this successfully, I synthesized elements of two geographic theories: point aggregation from cartographic generalization and hierarchical geographic ontology. My experimental design used synthetic 3D point data with spectral values. I employed the multi-dimensional Mean Shift clustering technique from the discipline of Computer Vision, and adapted a 3D range image segmentation accuracy assessment technique. I also contributed new techniques for segmentation quality assessment including two area under the curve indices and the development of new segmentation surface plots. Experimental evaluations included comparisons of the Mean Shift results with K-means clustering results, spatial resolution results, noise evaluation results, and the results of an alternative color configuration. I modified the variable sets to address uneven lighting conditions and employed the experimental methods to grouping real-world terrestrial LiDAR scan data. Though my new spatial relationship variable needs improvement, the methods yielded groups of points representing features in the LiDAR data and provided evidence of the potential for grouping richly attributed 3D points that represent geographic features.

Participants took part in three separate multiple stimulus without replacement (MSWO) preference assessments. One preference assessment contained all leisure stimuli, another all edible stimuli, and a final preference assessment that contained the top selected stimuli from the edible and leisure assessments. Their study found that 12 of the 14 participants selected edible stimuli over leisure stimuli in a combined preference assessment. Another recent study, Conine and Vollmer (2019) found similar results. However, our findings were different. Our results indicated that 11 participants selected edible stimuli as their most preferred stimulus and 14 selected leisure as their most preferred stimulus. This study also evaluated the effects of preference displacement in a combined preference assessment. The implication of our results suggest that preference is based on the individual and may be influenced by age, setting, and disability."--Page ii.

"When black beans are processed for consumption, they can lose their dark coloration due to the leaching of water-soluble pigments called anthocyanins. After hydrothermal processing, beans are commonly a faded brown color instead of the dark black color typical of the dry seed.

After hydrothermal processing, beans are commonly a faded brown color instead of the dark black color typical of the dry seed. The aim of this research was to develop mapping populations with different genetic sources of color retention in order to identify regions of the dry bean genome associated with canning quality traits. To this end, two half-sibling black bean recombinant inbred line (RIL) populations segregating for post-processing color retention were developed. These RIL populations were phenotyped for canning quality over two years and genotyped using the BARCBean6k_3 BeadChip. A novel phenotyping method using digital image analysis was shown to outperform current methods of quantitative color measurement. QTL for post-processing color retention were detected on six chromosomes, with QTL on Pv03, Pv08, and Pv11 being the most notable for their co-localization with QTL for quantitative measurements of color. In particular, QTL associated with color retention on Pv11 mapped to a very small physical interval and were consistent across years, populations, and phenotyping methodologies. Color retention QTL on Pv08 and Pv11 are good candidates for development of molecular markers that may be used in marker assisted selection (MAS) or early-generation screening to improve post-processing color retention in black beans."--Page ii.

An adhesively bonded Pi-/T-joint is a common ‘out-of-plane’ structural joint that connects a vertical (web) and a horizontal (base) load bearing substrates using an adhesive and a 3D-braided π (pi) preform. The stress-transfer between the substrates and the preform occurs through the adhesive bond-line via complex mechanisms that are governed by the loading condition and material properties of the substrates and the adhesive.

Show moreAn adhesively bonded Pi-/T-joint is a common ‘out-of-plane’ structural joint that connects a vertical (web) and a horizontal (base) load bearing substrates using an adhesive and a 3D-braided π (pi) preform. The stress-transfer between the substrates and the preform occurs through the adhesive bond-line via complex mechanisms that are governed by the loading condition and material properties of the substrates and the adhesive. Resistance strain gages and fiber optic sensors can only provide local/single-point measurement. Moreover, embedding them in the adhesive bond-line is impractical as they act as stress-concentrators and sites for the onset of failure. Optical techniques, especially the photoelasticity coating method, enables the full-field visualization of stress/strain fields. In this work, the Pi-/T-joints were made with aluminum substrates (both web and base) and a carbon fiber pi-preform using SC-15 resin as an adhesive. The joints were manufactured using the liquid resin transfer molding technique. The photoelasticity coating method was used to visualize and measure plane strains and stress directly on the joint using polarized light. The joints were experimentally tested in ‘out-of-plane’ (web pull-out) configuration until failure, and the isochromatic photoelasticity fringes or strain field images from the surface of the specimen were recorded. Force-displacement data were also characterized. Numerical models were developed using commercially available software ABAQUS®. Results show reasonably good agreement between the strain maps from photoelasticity and numerical simulations for similar load levels. Improvements in technique and modeling are suggested in order to improve agreement and to gain added insight into the complex behavior of these joints.

Olfaction impairment (OI) is a very common, but underreported, sensory deficiency among older adults that can lead to a host of adverse health conditions, quality of life issues, and is a predictor of 5-year mortality. Similarly, body composition and weight are driving factors of poor health among older populations, with malign effects including decreased mobility and sarcopenia. We theorize that older adults with OI both weigh less, and lose weight faster than those with without any...
Show moreOlfaction impairment (OI) is a very common, but underreported, sensory deficiency among older adults that can lead to a host of adverse health conditions, quality of life issues, and is a predictor of 5-year mortality. Similarly, body composition and weight are driving factors of poor health among older populations, with malign effects including decreased mobility and sarcopenia. We theorize that older adults with OI both weigh less, and lose weight faster than those with without any impairment. Our goal is to examine how OI associated with weight and weight loss two ways: 1) cross-sectional, where we assess the association during the year sense of smell was tested; and 2) longitudinally, where we inspect whether OI indicates more rapid weight loss over a seven-year period. The outcome variables of interest were total mass, total lean mass, total bone-free lean mass and total fat mass. Analyses were also performed in race-specific populations and in sex-specific populations. Data were obtained from the Health, Aging and Body Composition Study. The study found in the cross-sectional analysis that those with poor olfaction has significantly less total mass (-1.48 kg) and fat mass (-1.05 kg) than those with good olfaction. Longitudinally, those with poor olfaction showed a significantly faster decrease in total mass (-245.7 g/year), lean mass (-171.4 g/year) and bone free mass (-164.7 g/year) but not fat mass. Differing results were found in race-specific analyses but not in sex-specific analyses, with the decrease in weight appearing in whites but not blacks.

During the 2010 Deepwater Horizon oil spill, nearly 800 million liters of oil were released into the Gulf of Mexico polluting the deep ocean and more than 1600 km of the Gulf’s shoreline. A large amount (7 million liters) of oil dispersant, Corexit EC 9500A, was applied to the spill; as a result, the oil was emulsified into microdroplets that remained suspended in the water column. Even though small droplets biodegrade faster, they can pose significant environmental risks. Microfiltration is...
Show moreDuring the 2010 Deepwater Horizon oil spill, nearly 800 million liters of oil were released into the Gulf of Mexico polluting the deep ocean and more than 1600 km of the Gulf’s shoreline. A large amount (7 million liters) of oil dispersant, Corexit EC 9500A, was applied to the spill; as a result, the oil was emulsified into microdroplets that remained suspended in the water column. Even though small droplets biodegrade faster, they can pose significant environmental risks. Microfiltration is the one of the most cost-effective remediation technologies that can remove emulsified oil. The present work is the first study of membrane filtration of Corexit-stabilized crude oil emulsions where properties and filterability of the emulsions in aqueous solutions of different salinities are evaluated. Salinity of the continuous phase was altered by adding MgSO4, NaCl, or a synthetic sea salt mixture. Emulsions were characterized in terms of their droplet size distribution, interfacial tension, and zeta potential. Corexit altered both emulsion stability and the wetting properties of the membranes. Emulsion characterization and constant pressure stirred dead-end filtration tests revealed that salinity affects the stability of emulsions and can enhance microfiltration performance. Almost compete rejection of oil was achieved but was accompanied by a precipitous flux decline. The low values of the steady state permeate flux indicate that microfiltration is suitable as a polishing step that follows an extensive pretreatment by large throughput deoiling unit processes such as hydrocyclonic separation or flotation.
