Intelligent transportation systems; Air quality; Air--Pollution
Environmental or air quality impacts of Intelligent Transportation Systems (ITS)
are very difficult to measure. Some researchers have attempted to quantify the effects of
individual ITS application on emissions; yet, the effects of ITS as a whole...
Xenoestrogens are spread throughout the environment affecting our daily
lives and may produce potential toxic effects on human health. The purpose of
this study was to develop a mechanistically reliable model capable of identifying
xenoestrogens....
Hemolysis (red cells lysis) caused by fluid stresses in flows within hypodermic needles, blood pumps, artificial hearts and other cardiovascular devices, is one of the major concerns during the design and use of cardiovascular or blood-processing...
Ground-level ozone forecast models were developed for the following middle and small metropolitan areas in Kentucky: Ashland, Bowling Green, Owensboro, and Paducah. These models were nonlinear regression models, based on models previously developed...
Congenital stationary night blindness 1 (CSNBl) is a genetic disorder characterized in humans by night blindness, low visual acuity and myopia. CSNB 1 is caused by defects in genes that are involved in signaling between photoreceptors and...
There has been an increasing use of Unconventional Therapies in the past decade. These refer to healthcare interventions representing either a compliment or alternative to traditional medicine to which many people have turned in hope of attaining a...
An ensemble consists of a set of individual predictors whose predictions are combined. Generally, different classification and regression models tend to work well for different types of data and also, it is usually not know which algorithm will be...
This study compared brief, single sessions of physical activity (PA, self-paced treadmill walking) and relaxation/meditation (R/M, the "Body Scan") on positive and negative affect and anxiety measures in female undergraduates. Both were...
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...
African American children--Psychology; African American families; Developmental psychology--Social aspects; Parenting--Psychological aspects
The role of risk and protective factors in the family system on toddlers' social-emotional outcomes was examined by exploring the impact of depression and parenting strategies reported by female primary caregivers on toddlers' social-emotional...
The current study examined how Disclosure, Stereotype Disconfirming Information, and Stereotype Disconfirming Information and Disclosure Combined) influences an individual's stigma (stereotype endorsement, emotional reactions, and discrimination)...
Data from the Health and Retirement Study (HRS) were used to examine factors that influence emotional distress in older adults with cancer, arid to learn whether these distress trajectories are different from older adults without cancer. The model...
Cynicism--Kentucky--Louisville; Public opinion--Kentucky--Louisville; Metropolitan government--Kentucky--Louisville
The government's ability to gain and hold a high proportion of citizens' trust is essential to the functioning of an efficient and successful administration at the federal, state, and local levels. This thesis is a quantitative study aimed at...
Liver--Diseases--Genetic aspects; Liver--Effect of arsenic on; Arsenic--Toxicology
Arsenic exposure in drinking-water is a significant worldwide health problem. It causes adverse human health effects, such as cancer, increases the risks for others such as cardiovascular disease, and accelerates atherosclerosis. In this study, we...
The current study investigated narrative comprehension ability in children from low-income families by examining the contributions of temperament, attention skills, and cognitive engagement. Research has identified narrative comprehension skills as...
Equations of state attempt to describe the relationship between temperature (T), pressure (P), and molar volume (v) for a given substance or mixture of substances. The ideal gas law is the simplest form of an equation of state. An ideal gas can be...
African American families--Mental health; Parenting--Psychological aspects; Anxiety
To investigate the effects of anxiety and ethnicity on parental control as well as the effects ethnicity, anxiety, and parental control have on child diagnostic severity, anxious African American and Caucasian families were compared. Sixty-nine...
Mixed-effects model is an efficient tool for analyzing longitudinal data. The random effects in mixed-effects model can be used to capture the correlations among repeated measurements within a subject. The time points are not fixed and all...
