A Qualitative And Evaluative Study On Recruiting And Retaining Students In College Computer Science Programs, Matthew Gardner
A Qualitative And Evaluative Study On Recruiting And Retaining Students In College Computer Science Programs, Matthew Gardner
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Computer science is a discipline that is increasing in importance and value in our society, yet we are still failing to graduate a sufficient number of students to keep up with the demand required in the United States economy. We research several ways to retain students. We also discuss ways to increase students’ interest in the major, i.e., those who normally would not know about computer science. We discuss ways to increase female participation as well as overall participation in the major.

Heritability Of Cognition And Memory Loss In The Cache County Memory Study Cohort, Cassidy P. Allen
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
The Cache County Memory Study (CCMS) is a longitudinal study of the elderly in Cache County, Utah, that was initiated over twelve years ago to explore the role of APOE genotype and other environmental factors in dementia risk and cognitive function. Collaboration between the CCMS and investigators with the Utah Population Database (UPDB) at the University of Utah has revealed a significant number of sibships among the original 5,092 CCMS participants, along with complex pedigrees that include additional thousands of ancestors and relatives not enrolled in the Cache Study. Information about these families and pedigrees raises the potential for studies …
Secondary Electron Emission Study Of Annealed Graphitic Amorphous Carbon, Jodie Corbridge
Secondary Electron Emission Study Of Annealed Graphitic Amorphous Carbon, Jodie Corbridge
Senior Theses and Projects
In the 1880s a curious phenomena was observed: when a ray of light, no matter how weak, hit certain metals; electrons were emitted from the surface. Called the “photoelectric effect”, this puzzle was never explained until much later. In 1905, Albert Einstein put forth one possible explanation, which is currently accepted as correct. Einstein proposed that light propagated in discrete energy packets rather than as a continuous wave. While most scientists disbelieved Einstein theory, it was later proved in detail by Robert Milikan.1 Rays of light traveling in discrete packets hit metal surfaces, depositing energy. If the energy is high …

One of the responsibilities of the National Park Service is to identify nationally significant natural, cultural, and recreational resources and assist in their preservation both inside and outside the national park system. The areas managed by the National Park Service are only one part of a national inventory of special and protected areas managed by innumerable federal, state, and local agencies and the private sector. Consequently, addition to the national park system is only one of many alternatives for ensuring the preservation of significant national resources for public enjoyment and benefit. As such, the purpose of this study is to …

Ab Initio Study Of Intermolecular Potential Of H2o Trimer, G. Chalasinski, M. M. Szczesniak, P. Cieplak, Steve Scheiner
Ab Initio Study Of Intermolecular Potential Of H2o Trimer, G. Chalasinski, M. M. Szczesniak, P. Cieplak, Steve Scheiner
Steve Scheiner
Nonadditive contribution to the interaction energy in water trimer is analyzed in terms of Heitler–London exchange, SCF deformation, induction and dispersion nonadditivities. Nonadditivity originates mainly from the SCF deformation effect which is due to electric polarization. However, polarization does not serve as a universal mechanism for nonadditivity in water. In the double‐donor configuration, for example, the Heitler–London exchange contribution is the most important and polarization yields the wrong sign. Correlation effects do not contribute significantly to the nonadditivity. A detailed analysis of the pair potential is also provided. The present two‐body potential and its components are compared to the existing …

The recommendation for this WSA is to designate 17,150 acres of BLM land and 1,390 acres of State land as wilderness. This alternative is considered to be the environmentally preferable alternative as it would result in the least change in the natural environment over the long term. The entire 17,150 acres of federal land and 1,390 acres of state land within the WSA are recommended for wilderness designation and are shown on the Bobcat Draw Badlands WSA map. The state lands would be recommended for acquisition to enhance the manageability of the area as wilderness.

A Microsystem Sediment-Water Simulation Study For The Proposed Jordanelle Reservoir, Heber City, Utah, United States Department Of The Interior, Bureau Of Reclamation
Water
The technique of microsystem sediment-water simulation was used to predict water quality data for the proposed Jordanelle Reservoir, Heber City, Utah. Simulation microsystems were prepared for four sites located in the north arm of the reservoir basin including two sites located in an abandoned acid mine tailings pond. Data obtained from the tailings pond microsystems indicated that low pH water and high trace metal concentrations will exist in the north arm of the reservoir. These data suggested that some kind of membrane or compacted earth lining will be necessary to seal and contain the mine spoilage. Other sites in the …
