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.

Cow Insurance Vs. Human Insurance: A Comparison Study, Corlan Fawcett

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This paper will compare the premiums to insure cows and humans for n-year term, n-year endowment, and whole life insurance. It will go into more depth for whole life premium s that would be charged, such that the insurance company is 95 percent confident that they will not lose money. In particular the paper will look at how the variance affects the premiums for an insurance company insuring 100 cows.

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

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 …

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 …

All U.S. Government Documents (Utah Regional Depository)

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.
