Essays On Human Capital And Social Network Effects, Mahjuja M. Taznin

All Dissertations

The first chapter of this dissertation looks at the relationship between parental investment in daughters' human capital and marital transfers in India. I evaluate the existence, nature, and magnitude of a causal relationship between a daughter's education level and the price her family pays for a groom in India using nationally representative data and a two stage least squares instrumental variable estimation methodology. I construct a policy instrument using an Indian national school-latrine-construction initiative to estimate the effect of an exogenous increase in a woman's years of education on the groom price that her parents pay. My OLS estimates show …

Acceleration Of High-Fidelity Wireless Network Simulations, Madhabi Manandhar

All Dissertations

Network simulation with bit-accurate modeling of modulation, coding and channel properties is typically computationally intensive. Simple link-layer models that are frequently used in network simulations sacrifice accuracy to decrease simulation time. We investigate the performance and simulation time of link models that use analytical bounds on link performance and bit-accurate link models executed in Graphical Processing Units (GPUs). We show that properly chosen analytical bounds on link performance can result in simulation results close to those using bit-level simulation while providing a significant reduction in simulation time. We also show that bit-accurate decoding in link models can be expedited using …

A Comprehensive Framework For White-Box Damage Detection In Structural Systems Based On Extended Constitutive Relation Error Method, Xiaoyu Hu

All Dissertations

Early detection of the deterioration and degradation in civil infrastructure is critical for structural engineers and infrastructure managers to develop rehabilitation and maintenance plans. In the field of structural health monitoring, numerous techniques have been developed to detect and localize damage by examining changes in measured vibration response. Among vibration-based damage detection techniques, model-based approach has been widely used as its damage detection process incorporates the geometric configuration, physical properties, and behavioral characteristics of the structural system. However, the model-based approaches depend on a model calibration procedure that is based only on the outputs of numerical models without explicitly taking …

Trace Plutonium Geochemistry In Hydrogeological Systems Containing Natural Organic Matter, Nathan Alec Conroy

All Dissertations

Plutonium (Pu) mobility through the subsurface is dependent on the chemical composition of the source-term and biogeochemical conditions that impact its speciation. Regardless of future decision making, existing stockpiles of Pu need to be isolated from the biosphere. Therefore, understanding the speciation of trace Pu is essential for assessing and mitigating any risk of Pu transport from the source-term to a human or environmental receptor. After a brief introduction (Chapter One) and statement of research objectives (Chapter Two), this dissertation investigated Pu speciation under saturated conditions and in the presence of natural organic matter (NOM) and pure synthesized mineral phases. …

Putting Your Best Face Forward: The Influence Of Facial Cosmetics On Structured Employment Interview Ratings, Skye K. Gillispie

All Dissertations

Employment interviews are ubiquitous in modern selection systems. Although interviews are extremely common, there is evidence that interview ratings are subject to rating errors and biases. For example, previous research has found that higher physical attractiveness of the candidate is linked to increased interview ratings. Physical attractiveness is largely considered to be a fixed characteristic that cannot be controlled, however this may not be entirely true as research has consistently linked women's use of facial cosmetics to increased ratings of physical attractiveness. An experimental three (no cosmetics, low cosmetics, high cosmetics) by three (low performance, intermediate performance, high performance) design …

Targeting The Major Regulator Of Mitosis., J. Mason Hoffman

Electronic Theses and Dissertations

Mitosis-inhibiting chemotherapeutics (e.g. taxanes) are frequently used to treat multiple cancer types. Recently, there has been much concern about the limited success of these drugs due to resistance and a lack of molecular targets. Thus, there is high demand for new drugs with diverse cellular targets. Targeting the regulators of mitosis is a promising approach. The anaphase promoting complex/cyclosome (APC/C) is an E3 ubiquitin ligase that controls cell cycle progression at multiple points. The interaction of ANAPC2 and ANAPC11, catalytic core subunits, is necessary for APC/C function. An in silico approach was used to identify compounds predicted to prevent assembly …

Revenue Sharing And Player Salaries In Major League Baseball, James Richard Hill, Nicholas A. Jolly

Economics Faculty Research and Publications

This article analyzes how changes made to the revenue sharing agreement in the 2007 Major League Baseball collective bargaining agreement influenced the salaries of position players and pitchers. The tax rates associated with revenue sharing decreased following ratification of the 2007 agreement. Theoretically, these changes should increase players’ marginal revenue product and, therefore, salaries. Results indicate that position players experienced an increase in salary following the 2007 agreement. Pitchers’ salaries also increased, but by a smaller amount. The effect of the 2007 agreement was different throughout the salary distribution for position players, but uniform throughout the distribution for pitchers.

Impact Of Terminology Mapping On Population Health Cohorts Impact, Barbara A. Berkovich

Dissertations and Theses (Open Access)

Background and Objectives: The population health care delivery model uses phenotype algorithms in the electronic health record (EHR) system to identify patient cohorts targeted for clinical interventions such as laboratory tests, and procedures. The standard terminology used to identify disease cohorts may contribute to significant variation in error rates for patient inclusion or exclusion. The United States requires EHR systems to support two diagnosis terminologies, the International Classification of Disease (ICD) and the Systematized Nomenclature of Medicine (SNOMED). Terminology mapping enables the retrieval of diagnosis data using either terminology. There are no standards of practice by which to evaluate and …

Bayesian Model For Detection Of Outliers In Linear Regression With Application To Longitudinal Data, Zahraa Al-Sharea

Graduate Theses and Dissertations

Outlier detection is one of the most important challenges with many present-day applications. Outliers can occur due to uncertainty in data generating mechanisms or due to an error in data recording/processing. Outliers can drastically change the study's results and make predictions less reliable. Detecting outliers in longitudinal studies is quite challenging because this kind of study is working with observations that change over time. Therefore, the same subject can produce an outlier at one point in time produce regular observations at all other time points. A Bayesian hierarchical modeling assigns parameters that can quantify whether each observation is an outlier …

Validation & Optimization Of Capture™: Rapid Diagnosis Of Pathogens Causing Urinary Tract Infections, Elizabeth Gates

Perpetua: The Journal of Undergraduate Research at UAH

The number of bacterial strains resistant to antibiotics is growing exponentially. Antibiotics are often prescribed more than needed due to the delay period in diagnosing the pathogen and giving treatment. This delay often pushes prescribers to give a broad-spectrum antibiotic or pushes them to make the patient wait for the proper treatment, in turn allowing the bacterium to potentially mutate. This creates a need for a more rapid, easily used, and cost effective method of identifying pathogens. The objective of this study is to validate the CAPTURE™ method and its ability to identify pathogens, reduce the mechanical processing time, and …

Portraits, Preservation & Pedigrees: An Introduction To Photographic Portraiture, Photographs As A Means Of Genealogical Research, And A Preservation Case Study Of The Howard D. Beach Studio Collection Of Glass Plate Negatives, Kirsten Feigel

Museum Studies Theses

Photography is an established art form that combines the knowledge of chemistry, light, and optics to render an image. Initially, the image is captured on a flat surface coated with emulsion and combined with an exposure to sunlight or another illuminating source. Today, images are captured by digital methods. Artistically, the photograph may reveal sceneries of landscapes, of treasured belongings and of people, as they are seen to the human eye. Photographic portraiture is the oldest style of photography next to landscape imagery, due to commercial photographers setting up studios and experimenting with photography’s many cameras, plates, and emulsions. In …

"We Heard Canada Was A Free Country": African American Migration In The Great Plains, 1890-1911, Rachel M. Wolters

Dissertations

This study uses a transnational lens to examine the migration of Black Americans from Oklahoma to Canada in the early 20th century. Although scholars have documented this movement, they have not fully explored the vital and durable transnational connections among African American immigrants themselves. The use of family histories, newspaper articles, and immigration files show how black migrants searched for land and equality in Canada and attempted to build all black communities. Encouraged by the promises of Canadian immigration recruiters, black migrants left their homes and Jim Crowism in Oklahoma to settle in a “free country” and to realize the …

Clinical Predictors Of Movement Patterns In Patients With Chronic Ankle Instability, Seong Jun Son

Theses and Dissertations

BACKGROUND: Chronic ankle instability (CAI) patients have varying levels of mechanical and sensorimotor impairments that may lead to disparate functional movement patterns. Current literature on landing biomechanics in a CAI population, however, considers all patients as a homogeneous group. In our prior work, we identified 6 subgroups of movement patterns using lower extremity kinematics during a landing/cutting task and that showed promise in furthering understanding of movement patterns in a laboratory-based environment. To increase the utility of this methodology in clinical settings, there is a need to find easily administered clinical tests that can help identify multiple subgroups of movement …
