Social Vulnerability Index

description: The Social Vulnerability Index (SoVI) has served the hazards community well for more than a decade, but it is based on linear statistical methods. Using Utah as a test case, a state with a population exposed to a variety of hazards, this study sought to build upon the SoVI approach by augmenting it with a nonlinear Artificial Neural Network (ANN).  A SoVI was created for the state of Utah at the census block group level using five-year data (2008-2012) from the American Community Survey. The SoVI provided a dataset from which to train a neural network. The ANN was then used to classify a subset of the state to determine if it could provide a comparable classification of vulnerability. The ANN produced a vulnerability classification that was approximately 26% consistent with the SoVI created using the traditional approach. The differences in classifications were assessed using radar plots of block group variable averages to explore how the variables were handled in each classification. The results of this study warrant further investigation of the capabilities of an ANN-enhanced SoVI.

Behaviors Among Latino Migrant and Seasonal Farmworkers
Creators: name: Walton, AnnMarie Lee
Publisher: name: University of Utah
Year: 2016

description: Exposure to pesticides presents health risks for farmworkers. Pesticide protective behaviors (PPBs), including clothing and washing behaviors, reduce exposures. The Worker Protection Standard (WPS) mandates that PPBs be taught to farmworkers. PPB adherence and barriers must be understood to shape meaningful health policy, enact effective educational requirements, and test interventions that decrease pesticide exposure, minimizing adverse health outcomes for farmworkers. Using the Health Belief Model as a guide, this study explored farmworkers' adherence to WPS standards; their perceptions of threat of illness and cancer from pesticides; and their beliefs about benefits, facilitators, barriers, and strategies to mitigate barriers to PPB use. Seventy-two Latino farmworkers and three growers in North Carolina working on tobacco farms were enrolled. A prospective field observation and self-report design was utilized. Farmworkers were observed using more clothing than previously reported (90%-99% pants/long sleeves/closed shoes; 39% gloves), but had low rates of washing behaviors (0%-17%), even when supplies were available. Farmworkers' reported use of long pants and closed shoes was consistent with field observation; however, the use of long sleeves and gloves was more than was observed (97% vs. 90%, p = .028 and 83% vs. 39%, p = .000), and washing behaviors were markedly over-reported (43%-91% vs. 0%-10%, p = .000-.058). Farmworkers perceived pesticide exposure as an illness and cancer threat. iv They strongly endorsed the efficacy of clothing in minimizing those threats. While threat perception was not correlated with protective behaviors, findings suggest that protective clothing declined with greater agricultural experience. Farmworkers described wetness as the major obstacle to PPBs and reported concern for green tobacco sickness (GTS). They utilized hats and water-resistant outerwear, whose efficacy in minimizing pesticide exposure is unknown. Given higher rates of reported behaviors than observed, self-report should not be a proxy for actual behavior. Public health implications include increased emphasis on washing behaviors in training, and the potential benefit of moderately experienced farmworkers rather than more experienced farmworkers in reinforcing PPBs. For tobacco farmworkers in particular, pairing concerns about GTS and pesticide safety in training may improve adoption of protective behaviors.
Predictors of Malaria Prevention and Case Management Among Children Under Five in Three African Countries: Analysis of Demographic Health Surveys (DHS) Malaria Indicator Surveys
Creators: name: Adams, Megan Duncan
Publisher: name: University of Utah

description: The focus of this dissertation is threefold: conduct a systematic review to identify literature regarding the use of malaria control methods, identify rates of control method use, and identify predictors associated with the combined use of control methods among African children under age five through Demographic and Health Surveys (DHS). A systematic review identified literature regarding malaria control methods utilizing DHS surveys. Sixtyfive articles met the review criteria and were evaluated for insecticide treated nets (ITN) use, indoor residual spray (IRS), and prompt/appropriate treatment. While DHS datasets are a rich source to identify malaria practices in African children, additional research considering the combined use of malaria control methods is needed. DHS surveys from three countries at two separate time points were then analyzed to identify rates of children under five who reported fever and utilized one or more malaria control methods (ITNs, IRS, and/or prompt/appropriate treatment). Independent use of ITNs ranged from 30% to 75%, IRS from 1% to 18%, and prompt/appropriate treatment from 3% to 25%. Combined use of all control methods ranged between <1% to 3%. Within this descriptive analysis, while some improvements to using control methods were noted over time, independent and combined use of these methods are inadequate. Within the predictor analysis, using univariate, multivariate, and multinomial regression analysis, variables such as child age, maternal education, wealth index, and residence location were evaluated as possible predictors of the independent or combined use of these control methods. Higher maternal education and iv wealth were found to be significant predictors of using one malaria control method among some of the populations. The sample sizes for using two and three methods were extremely small and significant associations among the variables were few and sporadic. In summary, there were no predictors that remained consistent across all surveys. This final analysis demonstrates the necessity for further evaluation of availability, access, and effective dissemination of these control methods both singularly and in combination to improve the transmission and impact of malaria in these endemic populations.

description: Transport in strongly interacting Fermi gases provides a window into the non-equilibrium behavior of strongly correlated fermions. In particular, the interface between a strongly polarized normal gas and a weakly polarized superfluid at finite temperature presents a model for understanding transport at normal-superfluid and normal-superconductor interfaces. An excess of polarization in the normal phase or a deficit of polarization in the superfluid brings the system out of equilibrium, leading to transport currents across the interface. We implement a phenomenological mean-field model of the unitary Fermi gas, and investigate the transport of spin and mass under non-equilibrium conditions. We consider independently prepared normal and superfluid regions brought into contact, and calculate the instantaneous spin and mass currents across the normal-superfluid (NS) interface. For an unpolarized superfluid, we find that spin current is suppressed below a threshold value in the driving chemical potential differences, while the threshold nearly vanishes for a critically polarized superfluid. The mass current can exhibit a threshold in cases where Andreev reflection vanishes, while in general Andreev reflection prevents the occurrence of a threshold in the mass current. Our results provide guidance to future experiments aiming to characterize spin and mass transport across NS interfaces.

description: Parameter estimation is of foundational importance for various model-based battery management tasks, including charging control, state-of-charge estimation and aging assessment. However, it remains a challenging issue as the existing methods generally depend on cumbersome and time-consuming procedures to extract battery parameters from data. Departing from the literature, this paper sets the unique aim of identifying all the parameters offline in a one-shot procedure, including the resistance and capacitance parameters and the parameters in the parameterized function mapping from the state-of-charge to the open-circuit voltage. Considering the well-known Thevenin's battery model, the study begins with the parameter identifiability analysis, showing that all the parameters are locally identifiable. Then, it formulates the parameter identification problem in a prediction-error-minimization framework. As the non-convexity intrinsic to the problem may lead to physically meaningless estimates, two methods are developed to overcome this issue. The first one is to constrain the parameter search within a reasonable space by setting parameter bounds, and the other adopts regularization of the cost function using prior parameter guess. The proposed identifiability analysis and identification methods are extensively validated through simulations and experiments.

description: More than a century has passed since van't Hoff and Arrhenius formulated their celebrated rate theories, but there are still elusive aspects in the temperature-dependent phase transition kinetics of molecular systems. Here I present a theory based on microcanonical thermostatistics that establishes a simple and direct temperature dependence for all rate constants, including the forward and the reverse rate constants, the equilibrium constant, and the nucleation rate. By considering a generic model that mimic the microcanonical temperature of molecular systems in a region close to a first-order phase transition, I obtain shape-free relations between kinetics and thermodynamics physical quantities which are validated through stochastic simulations. Additionally, the rate theory is applied to results obtained from protein folding and ice nucleation experiments, demonstrating that the expressions derived here can be used to describe the experimental data of a wide range of molecular systems.

description: We investigate the effect of a non-Markovian, structured reservoir on an open Heisenberg spin chain. We establish a coherent self-feedback mechanism as the reservoir couples frequency-dependent to the spin chain. Thus, loss and driving take place due to the interaction of the spin chain with its own past. This new paradigm of non-Markovian imposed boundary-driving allows to discuss a new kind of non-equilibrium steady-state. We show that for certain parameters even in the long-time limit persistent oscillations occur within the chain. Moreover, we demonstrate that the conditions for these oscillations and excitation trapping depend on the characteristics of the chain, thus making it possible to characterize a chain by detection of its emitted signal under influence of self-feedback.

description: Over-the-Air (OTA) computation is the problem of computing functions of distributed data without transmitting the entirety of the data to a central point. By avoiding such costly transmissions, OTA computation schemes can achieve a better-than-linear (depending on the function, often logarithmic or even constant) scaling of the communication cost as the number of transmitters grows. Among the most common functions computed OTA are linear functions such as weighted sums. In this work, we propose and analyze an analog OTA computation scheme for a class of functions that contains linear functions as well as some nonlinear functions such as $p$-norms of vectors. We prove error bound guarantees that are valid for fast-fading channels and all distributions of fading and noise contained in the class of sub-Gaussian distributions. This class includes Gaussian distributions, but also many other practically relevant cases such as Class A Middleton noise and fading with dominant line-of-sight components. In addition, there can be correlations in the fading and noise so that the presented results also apply to, for example, block fading channels and channels with bursty interference. We do not rely on any stochastic characterization of the distributed arguments of the OTA computed function; in particular, there is no assumption that these arguments are drawn from identical or independent probability distributions. Our analysis is nonasymptotic and therefore provides error bounds that are valid for a finite number of channel uses. OTA computation has a huge potential for reducing communication cost in applications such as Machine Learning (ML)-based distributed anomaly detection in large wireless sensor networks. We illustrate this potential through extensive numerical simulations.

description: In this paper, we analyze the effects of expansion on large scale structure formation in our Universe. We do that by incorporating a cosmological constant term in the gravitational partition function. This gravitational partition function with a cosmological constant is used for analyzing the thermodynamics of this system. We analyze the virial expansion for this system, and obtain its equation of state. It is observed that the generalization of this equation of state is like the Van der Waals equation. We also analyze a gravitational phase transition in this system using the mean field theory. We construct the cosmic energy equation for this system of galaxies, and discuss its consequences. We obtain and analyze the distribution function for this system, using the gravitational partition function. We also compare the results obtained in this paper with the observational data.

description: We study interference patterns and Friedel oscillations (FO) due to scattering from two or more localized impurities and scattering from extended inhomogeneities in the two-dimensional lattice systems of interacting fermions. Correlations between particles are accounted for by using an approximate method based on the real-space dynamical mean-field theory and a homogeneous self-energy approximation (HSEA), where the site-dependent part of the self-energy is neglected. We find that the interference maxima and minima change systematically as we vary the relative distance between the two impurities. At the same time, the increase of the interaction does not shift the position of interference fringes but only reduces their intensities. A comparison with the single impurity cases clearly shows complex patterns in FO fringes induced by additional multiple scattering processes. In the case of an extended step like potential the system becomes more homogeneous when the interaction increases. FO and interference patterns are not present in the Mott insulating phase in both single and many impurity models.

description: We study the non-equilibrium response of a 4x3 Hubbard model at U=8 under the influence of a short electric field pulse, with the main focus on multiple photon excitations and on the change of double occupancy after the pulse. The behavior mainly depends on the driving frequency of the electric field. The largest change of double occupancy occurs during the pulse. For frequencies below the Mott gap, we observe multiphoton excitations at large field intensities. For frequencies beyond the gap energy, there is a region where Auger recombination reduces the double occupancy after the pulse. Impact ionization (Multi Exciton Generation), namely a growing double occupancy after the pulse, occurs for frequencies larger than twice the Mott gap. From the Loschmidt amplitude we compute the eigenstate spectrum of the quantum state after the pulse, observing multiple distinct photon excitation peaks, in line with expectations from a quasiparticle picture. We introduce a technique with which we analyze the time evolution of double occupancy in each peak individually. The long-term behavior of the double occupancy almost only depends on the absorbed energy, and we explore the connection of this property to the Eigenstate Thermalization Hypothesis.

description: With the prevalence of publicly available source code repositories to train deep neural network models, neural program models can do well in source code analysis tasks such as predicting method names in given programs that cannot be easily done by traditional program analysis techniques. Although such neural program models have been tested on various existing datasets, the extent to which they generalize to unforeseen source code is largely unknown. Since it is very challenging to test neural program models on all unforeseen programs, in this paper, we propose to evaluate the generalizability of neural program models with respect to semantic-preserving transformations: a generalizable neural program model should perform equally well on programs that are of the same semantics but of different lexical appearances and syntactical structures. We compare the results of various neural program models for the method name prediction task on programs before and after automated semantic-preserving transformations. We use three Java datasets of different sizes and three state-of-the-art neural network models for code, namely code2vec, code2seq, and GGNN, to build nine such neural program models for evaluation. Our results show that even with small semantically preserving changes to the programs, these neural program models often fail to generalize their performance. Our results also suggest that neural program models based on data and control dependencies in programs generalize better than neural program models based only on abstract syntax trees. On the positive side, we observe that as the size of the training dataset grows and diversifies the generalizability of correct predictions produced by the neural program models can be improved too. Our results on the generalizability of neural program models provide insights to measure their limitations and provide a stepping stone for their improvement.

description: The recent development of energy-resolving scintillation crystals opens the way to new types of applications and imaging systems. In the context of computerized tomography (CT), it enables to use the energy as a dimension of information supplementing the source and detector positions. It is then crucial to relate the energy measurements to the properties of Compton scattering, the dominant interaction between photons and matter. An appropriate model of the spectral data leads to the concept of Compton scattering tomography (CST). Multiple-order scattering constitutes the major difficulty of CST. It is, in general, impossible to know how many times a photon was scattered before being measured. In the literature, this nature of the spectral data has often been eluded by considering only the first-order scattering in models of the spectral data. This consideration, however, does not represent the reality as second- and higher-order scattering are a substantial part of the spectral measurement. In this work, we propose to tackle this difficulty by an analysis of the spectral data in terms of modeling and mapping properties. Due to the complexity of the multiple order scattering, we model and study the second-order scattering and extend the results to the higher orders by conjecture. The study ends up with a general reconstruction strategy based on the variations of the spectral data which is illustrated by simulations on a joint CST-CT fan beam scanner. We further show how the method can be extended to high energetic polychromatic radiation sources.

description: Network pruning has been known to produce compact models without much accuracy degradation. However, how the pruning process affects a network's robustness and the working mechanism behind remain unresolved. In this work, we theoretically prove that the sparsity of network weights is closely associated with model robustness. Through experiments on a variety of adversarial pruning methods, we find that weights sparsity will not hurt but improve robustness, where both weights inheritance from the lottery ticket and adversarial training improve model robustness in network pruning. Based on these findings, we propose a novel adversarial training method called inverse weights inheritance, which imposes sparse weights distribution on a large network by inheriting weights from a small network, thereby improving the robustness of the large network.

The influence of caring, curiosity, and knowledge on  visitors' conservation intentions: an exploratory investigation  at the Tracy Aviary

description: Rapid development and population growth challenges society to adopt behaviors that help conserve vital environmental resources. Zoos play an important role in this challenge because they receive millions of visitors annually and have opportunities to influence visitors' willingness to conserve important resources. Previous research in visitor outcomes has shown that after a zoo visit, people express intentions to engage in conservation actions, at least in the short term. I used Tracy Aviary's mission, "inspire curiosity and caring for birds and nature through education and conservation" to explore different variables that may influence visitors' conservation intentions. These variables were level of engagement, knowledge (objective and subjective), past visitation, curiosity, and conservation caring. Through three research questions, I sought to understand relationships among these variables, as well as identify the strongest predictor(s) for visitors' conservation intentions. I administered questionnaires to a sample of 609 visitors between June and July, 2015. Results indicate that caring was the strongest single predictor for visitors' conservation intentions (predicting 53% of the variance) and caring scores increased as a result of a single visit. Subjective knowledge (what people think they know) influenced curiosity and caring more than objective knowledge (what they actually know). Curiosity had the highest values pre- and postvisit among all predictors, but was not a strong predictor of visitors' conservation intentions. Overall, these results provide points for discussion and can inform conservation education messaging, visitor outreach, and programming.

description: A batch reactor device utilizing photocatalysis and a flow reactor combining photocatalysis and photoelectrocatalysis were developed for bacterial disinfection in lab-synthesized and natural waters. The batch reactor provided a 90% decrease in initial concentration (~1 x 103 CFU/mL) after 60 minutes when subjected to incident light at 100 mW/cm2 and continuous mixing via aeration. A combination of photocatalysis and photoelectrocatalysis in the flow reactor provided complete inactivation of contaminated waters with flow rates of 50 mL/min. Both devices consisted of immobilized titanium dioxide nanotube arrays as the catalyzing medium. The flow reactor used an applied bias of up to 6 V without noticeable water splitting. Light intensity, applied voltage, and background electrolytes and concentration were all found to impact the device performance. Complete inactivation of E. coli W3110 (800 CFU/mL) occurred in 15 seconds in the flow reactor irradiated at 25 mW/cm2 with an applied voltage of 4 V in a 100 ppm NaCl solution. Disinfection in natural water was inhibited by the presence of inorganic ions and other constituents that are commonly found in natural water. To simulate natural scenarios in which a point-of-use device might be employed, testing was conducted in a natural environment using source water from Emigration Creek in Salt Lake City, Utah. A higher voltage of 6 V was required to reach 100% inactivation in natural surface water. The nanotube flow through disinfection chamber shows promise as a personal point-of use device for E. coli inactivation.
Evaluating the environmental impact of woody biomass removal for biofuel production

description: Bioenergy is necessary to meet future world-wide energy demands while helping to offset the global impacts of increased carbon dioxide from traditional fossil fuels. Options for producing bioenergy without adversely impacting food, water, and other environmental resources are currently being explored including using woody biomass as feedstock. Key issues among stakeholders include soil and water quality and loss of biodiversity as collecting small-diameter woody biomass may significantly alter post-timber harvesting landscapes. Linkages between land use changes and runoff, erosion, and sedimentation processes in river basins are known to exist but little is known about how land use changes impact the entire ecological function of the watershed. The objectives of this study were to explore using changes in microbial soil populations as a function of woody biomass removal treatment scenarios to determine potential changes in long-term water export and nutrient ecology, measuring changes in sediment erosion and collecting data to measure changes in infiltration/evaporation. This will help us understand the environmental impacts of biomass removal in the production of jet fuel and will be the start of holistic river basin management strategies focused on hydrologic implications of the entire food web. Microbial population data were collected from 28 one-acre plots subject to different land treatments and analyzed statistically to evaluate a null hypothesis that changes in biomass removal do not impact subsurface environment. Finger printing analysis and bio diversity index were calculated to understand the impact from a biological point of view. Sediment erosion was estimated using the WEPP model and then we tried to compare the model result with observed result. Results indicate that significant removal of biomass is possible without statistically altering the microbial food web, and the sites possessed such unique characteristics for which parameterization of the WEPP model for the whole Pacific Northwest is not possible using the data of these sites. Longer term analysis of soil infiltration and site runoff are needed to quantify the role of climate condition on these findings.

description: The Einstein-Podolsky-Rosen (EPR) paradox plays a fundamental role in our understanding of quantum mechanics, and is associated with the possibility of predicting the results of non-commuting measurements with a precision that seems to violate the uncertainty principle. This apparent contradiction to complementarity is made possible by nonclassical correlations stronger than entanglement, called steering. Quantum information recognises steering as an essential resource for a number of tasks but, contrary to entanglement, its role for metrology has so far remained unclear. Here, we formulate the EPR paradox in the framework of quantum metrology, showing that it enables the precise estimation of a local phase shift and of its generating observable. Employing a stricter formulation of quantum complementarity, we derive a criterion based on the quantum Fisher information that detects steering in a larger class of states than well-known uncertainty-based criteria. Our result identifies useful steering for quantum-enhanced precision measurements and allows one to uncover steering of non-Gaussian states in state-of-the-art experiments.

description: Recently we developed a noniterative real-time image reconstruction algorithm for real-time magnetic resonance imagining, in which the k-space is undersampled.  The developed algorithm was in the form of filtered backprojection (FBP) and was able to minimize a quadratic constrained objective function.  This thesis investigates the possibility to extend this FBP-MAP (Filtered Backprojection, Maximum a Posteriori) algorithm by introducing more controlling parameters.  Thus, our original FBP-MAP algorithm became a special case of the extended FBP-MAP algorithm.  A cardiac patient data set is used in this thesis to evaluate the extended FBP-MAP algorithm, and the result from a well-established iterative algorithm is used as the gold standard.  If the parameters are selected properly, the extended FBP-MAP algorithm can outperform the original FBP-MAP algorithm.
