Bayesian Item Response Theory: Statistical Inference And Power Analysis, Jason W. Bodnar Jan 2011

Bayesian Item Response Theory: Statistical Inference And Power Analysis, Jason W. Bodnar

Dissertations

The regulatory pharmaceutical approval process is flawed in that industry clinical trials (ICTs) are always powered for efficacy and rarely powered for safety. The key safety parameter is the adverse event (AE). This practice may result in efficacious products with confounded safety. An ICT’s ability to be powered for detecting AE trends may improve patient safety. Therefore, this dissertation’s purpose was to determine if power analysis resulted in feasible sample sizes for substantiating AE hypotheses. AEs were modeled with three Bayesian 2PL IRT models. The unidimensional latent trait, transfusion-related AE, was modeled as a patient predisposition for experiencing ...

How Politics, Economics, And Technology Influence Evaluation Requirements For Federally Funded Projects: A Historical Study Of The Elementary And Secondary Education Act From 1965 To 2005, Maxine R. Eversley-Gilling Jan 2011

How Politics, Economics, And Technology Influence Evaluation Requirements For Federally Funded Projects: A Historical Study Of The Elementary And Secondary Education Act From 1965 To 2005, Maxine R. Eversley-Gilling

Dissertations

Program evaluation does not take place in a vacuum. Its context is the interaction of political, economic, and technological developments that influenced the formation of federal policies for mandated evaluation requirements. The Elementary and Secondary Education Act (ESEA) of 1965 established policies to provide “financial assistance to local educational agencies serving areas with concentrations of children from low-income families to expand and improve their educational program” (Public Law 89-10—Apr. 11, 1965). This legislation also had another consequence: it helped drive the establishment of educational program evaluation and the field of evaluation as a profession.

The purpose of this study ...
