Show moreUrban development poses multiple problems, including environmental pollution, a reduction in biodiversity, and the disappearance of the natural environment. Man-made environments and structures consume a large amount of limited natural resources through their extensive use of energy and materials. This research explored the use of vegetation in building facades as a potential solution to the problems of urban ecology and the excessive energy consumption in buildings. Vegetated facades have the ability to reduce building energy use, reduce the urban heat island effect, improve air quality, and increase the biodiversity of plants and animals in cities. The goal of this research was to evaluate the effects of plants on thermal performance and energy consumption of buildings by developing a thermal model of a building facade covered with a layer of plants. The developed mathematical model accounts for thermal physical processes in a vegetated exterior wall, including solar radiation, infrared radiative exchange between the facade and sky, the facade and ground, the facade and vegetation layer, convection to and from the facade, evapotranspiration from the plant layer, heat storage in the facade material, and heat conduction through the facade. The model calculates vegetated facade surface temperature and heat flux through the facade for multiple weather conditions, plant physiological characteristics, and facade properties. The model was validated with the results of a week-long experiment measuring the thermal properties of bare and vegetated facades on a building at the Illinois Institute of Technology campus. The experiment and subsequent sensitivity analysis demonstrated that a plant layer can effectively reduce the facade exterior surface temperature, daily temperature x viii fluctuations, exterior wall temperature gradient, and, as a result, provide as much additional thermal insulation to the facade as a 2.5 cm layer of expanded polystyrene insulation, depending on a range of plant parameters. The vegetated facade model was also used to analyze the reduction in energy consumption in generic office and residential thermal zones for multiple parameters. The simulations showed that energy reduction could be as high as 6.2% of annual total energy use and 34.6% of cooling energy use in residential thermal zones, depending on building characteristics, plant parameters, and climate zone. Overall, the vegetated wall model developed and validated herein provides a new tool for evaluating the impact of plant layers on facade thermal performance in existing buildings retrofitted with green walls and for designing green walls for optimal energy efficiency in new construction.

Show moreThe current study reports the findings from a Monte Carlo investigation examining the potential impact on the organizational utility of two independent factors, socially desirable responding (faking) and a curvilinear relationship between personality and job performance, for organizations choosing to use personality tests in a selection setting. This study explores the impact of faking on the observed predictive validity (𝑜𝑏𝑠𝑟𝑥𝑦) and utility of the test, as well as the impact on the composition and job performance of the selected group (𝑧𝑠𝑒𝑙) when using non-faked scores as opposed to faked scores. In addition, this study hypothesizes a curvilinear relationship between personality and performance, and examines the impact of this non-linear relationship on 𝑜𝑏𝑠𝑟𝑥𝑦, utility and 𝑧𝑠𝑒𝑙 . The study simulates several variables that are likely to differ across selection scenarios, including the true predictive validity of the test (𝑟𝑥𝑦 ), the correlation between faking and job performance (𝑟𝑧𝑦), selection ratio (𝑠𝑟), average tenure (T) and various levels of the standard deviation of performance in dollars (𝑆𝐷𝑦). Consistent with previous research, results show a relatively minor impact on 𝑜𝑏𝑠𝑟𝑥𝑦 caused by faking, though more significant changes in utility and 𝑧𝑠𝑒𝑙 . This relationship is greatly impacted by the correlation between faking and performance (𝑟𝑧𝑦), where results show a detrimental impact on the outcome variables when this relationship is negative. However, when this relationship is positive, faking serves to augment the quality of selection systems. Results also indicate that a curvilinear relationship between personality and performance results in much more significant changes to 𝑜𝑏𝑠𝑟𝑥𝑦, utility and the 𝑧𝑠𝑒𝑙 . Implications and directions for future research are also discussed.

Show moreDr3OR2.1 olfactory receptor is located in the zebrafish chromosome 2. It is initially reported as the only member presented in zebrafish olfactory receptor genes θ group. The functional study of Dr3OR2.1 is lacking. In order to find out the ligands that might activate Dr3OR2.1, a preliminary chemical screening was conducted in this study. Dr3OR2.1 was cloned from zebrafish cDNA library and inserted into pCI mammalian expression vectors with Rho-tag and without tag. The Dr3OR2.1 was transfected into Hana3A cells and tested for its cell-surface expression by immunocytochemistry. Ten amino acids and four bile acids were tested on Rho tagged and no tag Dr3OR2.1 transfected Hana3A cells. The result indicated that the presence of N terminal Rho-tag may cause the differences between the odorant response profile of these two Dr3OR2.1 constructs. In addition, Dr3OR2.1 is probably an amino acid olfactory receptor rather than a bile acid olfactory receptor.

Show moreCreativity researchers continue to debate whether the phenomenon of creativity is a uniform construct regardless of context, or if creativity differs characteristically across domains. The present research contributes to this debate by way of an analysis of creative work. It was hypothesized that a comprehensive analysis of creative work would reflect a four-factor structure that is often used to organize the creativity research literature. Additionally, differences in both the level and nature of creativity were expected to emerge from incumbent data across occupational domains. An eight-factor, rather than four-factor structure of creative work was observed. Incumbent ratings from seven distinct job families were different in nature but not level of creative work.

Show moreThe modern conceptualization of delusional ideation is that it is a multidimensional construct that lies on a continuum with normality. Higher levels of delusional ideation have been associated with lower levels of quality of life. In contrast, higher levels of mindfulness have been related to higher levels of quality of life. This study examined the associations among delusional ideation, mindfulness, and quality of life in a community sample (N = 493). Correlation and mediation analyses were conducted to examine 1) the association between delusional ideation and mindfulness, 2) the association between .mindfulness and quality of life, and 3) whether the association between delusional ideation and quality of life was mediated by mindfulness. Results supported study hypotheses, indicating that delusional ideation was negatively associated with mindfulness and quality of life and that mindfulness was positively associated with quality of life. In addition, mindfulness mediated the relation between delusional ideation and quality of life. Findings have important implications for treatment and prevention efforts. Mindfulness may be an important goal for intervention in order to lessen the impact of delusional ideation in reducing quality of life.

Show moreOlfactory imprinting is the process of producing life-long changes through neural modification that is independent of associative learning. Here, I provide data to demonstrate that olfactory imprinting in zebrafish leads to neurobiological and behavioral changes. I treated zebrafish with an amino acid (AA) or a bile acid (BA) mixture from 4 days post-fertilization (dpf) to 40 dpf. Behavior studies showed that fish treated with odorants for 40 days exhibited preferential responses to treated odorants, which was different from the controls. These behavioral changes were retained 3 months after the odor treatment was ceased. Whole-mount immunohistochemistry was conducted using antibodies for parvalbumin (PV) and OTX. We discovered that treated fish had increased PV and OTX expression in the olfactory epithelium (OE) at 7 dpf and increased PV expression in the olfactory bulb (OB) at 12 dpf. Detailed analysis indicated that increased PV expression was observed in the OE apical region of treated groups while OTX was increased in both the apical and basal regions of the OE. In three regions of the OB analyzed, BA treated fish showed a doubling in PV expression in all regions while doubling was in two regions in AA treated fish. Increased OTX expression was in the three regions of AA treated fish but not in BA treated fish. These data demonstrate that exposure to AA or BA during zebrafish development leads to long-lasting physiological and behavioral changes. The report also includes a study of embryonic zebrafish treated with SP600125 (anthrapyrazolone), an inhibitor of the c-Jun N-terminal kinase (JNK) signaling pathway. Zebrafish embryos were treated with 1.25 μM, 5 μM, or 12.5 μM of SP600125 from 18 to 48 hours post-fertilization (hpf) followed by evaluation at 120 hpf. Zebrafish treated at 1.25 μM were not affected developmentally while embryos treated at xv 5 μM and higher displayed numerous morphological defects including edemas, eye malformations and reduction in olfactory organ size. Overall, it was observed that treatment at 5 μM, SP600125 caused severe developmental defects and that these defects worsened with increasing concentrations. Taken together, these data indicate that the environment has a profound influence on zebrafish development.

Show moreThis work describes the Very Energetic Radiation Imaging Telescope Array Systems (VERITAS) observations of the starburst galaxy M82 by documenting the analysis of 231 quality-selected hours of observational data taken between 2008 and 2014. The prototypical starburst galaxy, M82’s high supernova (SN) rate and dense central accumulation of molecular gas make it a promising candidate for studying cosmic ray (CR) acceleration and propagation with the detection of di↵use very high energy (VHE; approximately 100 GeV-100 TeV) !-ray emission. This di↵use emission is predicted to result from proton-proton interactions within the galaxy’s core that produce VHE !-rays through neutral pion decay. This work confirms the results of the initial VERITAS publication covering 137 hours of M82 observations between January 2008 and April 2009, yielding a total of 103.5 excess !-ray-like events (0.007 !/min, 5.7 pre-trial statistical significance) from a deeper exposure of 231 hours of observation. The spectral properties found are in agreement with the original detection within errors ("=2.85 ± 0.39). These results are consistent with paradigms that describe the production of CRs via the conversion of mechanical energy generated in supernovae (SNe). These findings will improve current di↵use emission models by better constraining galaxy parameters and by providing insight into CR proton loss processes and timescales, with further understanding to be gained with the introduction of the Cherenkov Telescope Array (CTA). xiiThis work describes the Very Energetic Radiation Imaging Telescope Array Systems (VERITAS) observations of the starburst galaxy M82 by documenting the analysis of 231 quality-selected hours of observational data taken between 2008 and 2014.

Show moreAccurate and sensitive discrimination of cancerous tissue from the healthy tissue has been a difficult problem to deal with, resulting in the incomplete resection of cancerous tissue and giving rise to ‘call-back’ surgery. Fluorescence guided surgery, which employs a fluorescent imaging agent to highlight key molecular differences between cancerous and healthy tissue is a promising approach for improving cancer discrimination during tumor resection surgery. However, conventional fluorescence guided surgery methods have not been optimized in terms of maximizing the contrast of cancer to healthy tissue and nonspecific sources of contrast in images can potentially obfuscate the reliability of such approaches, typically owing to variable vascular permeability and retention kinetics of fluorescent imaging agents in cancerous tissues. Paired-agent approaches have been proposed to account for these nonspecific factors. The approaches employ co-administration of a control (untargeted) imaging agent with a cancer targeted imaging agents, the measured signal of which is used to “normalize” out nonspecific components of targeted agent distribution so that the highest possible contrast between cancer and healthy tissue can be realized. This thesis explores how tumor contrast can be optimized by a ratiometric application of paired-agent imaging approach depending on pharmacokinetic characteristics of the targeted and control imaging-agents used. Overall, two parameters were found to be of upmost importance: 1) the plasma elimination half-life of the imaging agents should be long or large compared to the tissue efflux rate, k2, ideally > 10 h for typical k2 levels; 2) the efflux rate of the imaging agents from the extracellular space to the intravascular space needs to be relatively high in the range of 0.05-0.13 min-1. This thesis also highlights the importance of the appropriate imaging time while quantifying the cell surface receptors. With the use of simulations and animal models this thesis identifies the use of kinetic parameters playing a role in the paired-agent imaging approach. By making use of the paired-agent imaging approach in the fluorescence guided surgery it would be possible to accurately quantify the cancer cell surface receptors to optimize identification of the cancerous tissue from the healthy tissue.

Show moreSimulation fidelity refers to the level of realism with which the simulation is presented, as well as the method in which applicants can respond. Work simulations have been shown in previous literature to be beneficial selection tools. However, the research is less concrete with regard to the effects of various levels of fidelity (specifically, high fidelity virtual environments) on important organizational outcomes. In the current study, a model of fidelity is presented and 322 participants completed one of four simulation conditions (high fidelity, low fidelity/no branching, low fidelity/branching, zero fidelity). Face validity, applicant reaction, presence/immersion/engagement, predictive validity, and reliability were measured as outcomes of interest from the model. The findings indicated that the high fidelity condition and the low fidelity conditions had increased fidelity, fairness, face validity, and presence/immersion/ engagement compared to the zero fidelity condition. However, the addition of branching to the low fidelity simulation did not impact the hypotheses in the expected direction. The hypothesis regarding predictive validity was not supported, and the hypothesis regarding reliability was partially supported. Implications of the findings, limitations, and recommendations for future research are presented.
