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...
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...
New firms face financial constraints that could hinder firm performance. Yet founders exhibit persistence and resourcefulness in building their new ventures and finding solutions to their financial constraints. The use of financial theories that...
The phase II clinical trial is a critical step in the drug development process. In the oncology setting, phase II studies typically evaluate one primary endpoint, which is efficacy. In practice, a binary measurement representing the response to the...
This project examines the Conservation in Action series, twelve texts produced by the United States Fish and Wildlife Service (USFWS) from 1947-1957 and developed and written by Rachel Carson and other agency employees. She developed the series to...
Pattern perception--Data processing; Pattern recognition systems; Land mines--Detection; Data mining
For complex detection and classification problems, involving data with large intra-class variations and noisy inputs, no single source of information can provide a satisfactory solution. As a result, combination of multiple classifiers is playing...
Pattern recognition systems; Land mines--Detection; Pattern perception--Data processing; Data mining
Traditional machine learning and pattern recognition systems use a feature descriptor to describe the sensor data and a particular classifier (also called "expert" or "learner") to determine the true class of a given pattern....
Children with disabilities--Education (Secondary); Vocabulary--Study and teaching (Secondary); Mathematics--Study and teaching (Secondary)
Constant Time Delay (CST) has been used extensively as a procedure to teach children with disabilities a variety of skills. There is a preponderance of evidence that this instructional strategy is a highly effective (Handen & Zane, 1987;...
Learning and scholarship--Outlines, syllabi, etc.; English language--Rhetoric-- Outlines, syllabi, etc.; Education, Higher--Curricula; Instructional systems--Design
This dissertation is an investigation of composition's disciplinary conceptions of the course syllabus, from its often-relegated position as textual object to a more interactive and complex subject of our discipline. The course syllabus is an...
Current high-throughput gene expression experiments have a straightforward design of examining
the gene expression of one group or condition relative to that of another. The data is typically
analyzed as if they represent strictly intracellular...
Student counselors--Kentucky--Attitudes; Student counselors--Training of
This study addressed the administrative task of recruiting school counselors in the largest school district of Kentucky, a state undergoing systemic school reform. The participants (N = 553) were elementary (n = 162), middle (n = 113), and high (n...
The concept of quality of life (QOL) has been the topic of many research projects, yet several clinically relevant aspects of this concept have been overlooked. Specifically, few studies have addressed the impact of such demographic variables as...
College dropouts--Prevention; Social work education--Kentucky--Louisville; Social workers--Training of--Kentucky--Louisville; Academic achievement--Kentucky--Louisville
This study tested a hypothetical model for predicting both graduate GPA and graduation of University of Louisville Kent School of Social Work Master of Science in Social Work (MSSW) students entering the program during the 2001-2005 school years....
Children's literature in mathematics education; Mathematics--Study and teaching (Elementary); Problem youth--Education (Elementary); Mathematics--Remedial teaching
Nationally, there are increasing numbers of students who are at-risk for academic and/or social failure (U.S. Department of Education, 2009). In an attempt to address this trend, the 2004 reauthorization of the Individuals with Disabilities...
G-quadruplexes are thought to have biological importance, with studies based on small molecule interactions and quadruplex-interactive antibodies demonstrating their potential for formation in vivo. One potential biological function of quadruplex...
Critical thinking--Study and teaching (Higher); Critical thinking--Ability testing; Social work education
This study utilized the standardized California Critical Thinking Skills Test (CCTST) Form 2000 to measure students' pretest and post test critical thinking abilities prior to and upon completion of a critical thinking infused curriculum. In...
Medical records--Data processing; Data mining; Databases--Design
A major problem with integrating information from multiple databases is that the same data objects can exist in inconsistent data formats across databases and a variety of attribute variations, making it difficult to identify matching objects using...
For complex classification systems, data is usually gathered from multiple sources of information that have varying degree of reliability. In fact, assuming that the different sources have the same relevance in describing all the data might lead to...
African American men--Employment; African American men--Attitudes; Mentoring in business; Job satisfaction
This dissertation is a correlational designed study that examined the strength and direction of the relationship between mentoring, job satisfaction, and organizational commitment, of African American men, exclusively in a business setting (N =...
