Trees in cities--Kentucky--Louisville; Urban forestry--Kentucky--Louisville; Louisville (Ky.)--Environmental conditions
Trees in urban residential neighborhoods provide valuable ecosystem services. Urban trees also face threats from disturbances, such as storms. In 2008, the Urban Forest Effects model was used to estimate abundance and species composition of...
Premenopausal women have fewer and less severe strokes when compared to postmenopausal females and aged matched males. The most obvious factor that could account for the observed difference is the physiological activity of Estrogen. Numerous...
Clustered longitudinal data is often collected as repeated measurements on subjects over time arising in the clusters. Examples include longitudinal community intervention studies, or family studies with repeated measures on each member. Meanwhile,...
Voting research; Press and politics--United States--History--21st century; Mass media--Political aspects--United States--History--20th century; Presidents--United States--Election--2000; Presidents--United States--Election--2004
Scholars have long considered the role media play in shaping levels of political knowledge and voting behavior. The specific context of this study is the 2000 and 2004 presidential elections. It examines the influence of newspaper reading,...
In this dissertation research, we aim to solve problems of two types of survival data, clustered survival data with potentially informative cluster size and sojourn time data. The methods for these two types of data are different. However, both...
The complexity of high-dimensional data creates a number of concerns when trying to analyze it. This data often consists of a response or survival time and potentially thousands of predictors. These predictors can be highly correlated, and the...
RNA--Analysis; Probability measures; Genetics--Research--Methodology
The present experimental designs have unique challenges in the analysis of microRNA
expression intensity levels. In this project, various Normalization techniques were
discussed with different statistical techniques and their application in an...
This work develops a method of estimating peak daily streamflow, Qpeak, for Kentucky streams using daily average streamflow, Qave, data from the United States Geological Survey's (USGS) National Water Information System (NWIS) website. The purpose...
Medical appointments and schedules; Simulation methods
Healthy for Life is a relatively new University of Louisville medical clinic which attempts to stem the epidemic of childhood obesity. This program offers a range of face-to-face services for overweight children. The main problem addressed by this...
A quarter of a century ago, Abraham Epworth Rounds, aged forty-five, came shambling out of mountainous Eastern Tennessee to one of our Kentucky cities. He was intent on making a living in easier fashion than scratching it from the lean soil of the...
Heart--Hypertrophy; Hydrogen sulfide--Therapeutic use
Background: Although matrix metalloproteinase (MMPs) and tissue inhibitor of metalloproteinase (TIMPs) play a vital role in tumor angiogenesis and TIMP-3 causes apoptosis, their role in cardiac angiogenesis is unknown. Interestingly, a disruption...
In submitting this thesis, the writer does not pretend to have made even an approximation of exhaustive study of the Hecyra: this thesis is merely a study of the play from certain viewpoints which also make no claim to completeness. No originality...
This research was performed to establish the feasibility of using Direct Metal Deposition (DMD) technology to deposit nickel powder to a nickel substrate. The substrate is electrodeposited pure nickel, and the material to be deposited is Metco...
In the year 1573 when Shakespeare and Marlowe were already boys of nine, Chapman in adolescence, Spenser, Lyly and Richard Hooker men of twenty, John Donne, then important to only a few but destined to the company of royalty, was born. Walton...
Freshwater zooplankton; Global warming; Nitrogen--Environmental aspects
Aquatic ecosystems face major transformations as humans increasingly alter their environment by introducing exotic species and changing the temperature regime and nutrient availability of freshwater systems. The impacts of such alterations of...
The objective of my dissertation research was to determine the role of chemical signals in conveying information regarding an individual's health status and suitability as a mate in humans and to examine the role that commensal microflora play in...
Thirty smokers were solicited from the Wichita, Kansas community via the newspaper and broadcast media for a stop-smoking project. The volunteers were assigned to one of two treatments: double smoking or a modification of Von Dedenroth's (1964)...
Item response theory; Goodness-of-fit tests; Monte Carlo method
Item response theory (IRT) is expanding to diverse research settings, without accompanying access to easily implemented model fit methods. One simple model fit approach involves x2/df ratios. However, its utility is not known across several...
Soon after the atomic theory was established, it was found that the plant uses as sources of food not only the air and water, but also different constituents of the soil, dissolved in the soil moisture—the mineral nutrients. Ashes of different...
Missing data is very common in survey research. However, currently few guidelines exist with regard to the diagnosis and remedy to missing data in survey research. The goal of this thesis was to investigate properties and effects of three selected...
