The United States is struggling to provide health care in the face of ever increasing demand. As medical students continue their decades long march toward specialization, questions of how to provide generalist care become quickly intertwined with that of who…

In this thesis we develop and test methods for numerically evolving hydrodynamics coupled to the Einstein field equations, and then apply them to several problems in gravitational physics and astrophysics. The hydrodynamics scheme utilizes high-resolution shock-capturing techniques with flux corrections…

Single-particle reconstruction of vitrified samples (cryogenic electron microscopy, or









cryo-EM) provides structural information for a large variety of biological molecules,









ranging from…

Machine learning is the science of discovering knowledge from data and making decisions based on this learnt structure. It has grown into a broad discipline that has established many statistical and computational learning principles. We are surrounded by the applications…

The aim of this thesis is to develop methods for variable selection and statistical prediction for high dimensional statistical problems. Along with proposing new and innovative procedures, this thesis also focuses on the theoretical properties of the proposed methods and…

It was hypothesized that children with physical disabilities would show a deficit in procedural and declarative knowledge of ball catching compared to age-matched non-disabled children. The first group of children consisted of sixteen children with physical disabilities, three girls and…

The high rate of sexually transmitted diseases and teen pregnancies among the Cree adolescents indicate that this population frequently engages in unprotected sexual activities. AIDS is a critical health problem worldwide and AIDS contamination within a Cree community could be…

The main objective of the present work is to investigate the nature of the cognitive processes responsible for the problem-solving operations of novices, intermediates, and experts in a semantically rich and complex domain, i.e. electronics trouble shooting, in relation to…
