All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
On March 25, 1999, the National Marine Fisheries Service (NMFS) listed the anadromous Oncorhynchus mykiss (O. mykiss), or steelhead, population in the Middle Columbia Evolutionarily Significant Unit (ESU) as threatened under the Endangered Species Act, and deemed that the federal Columbia River Hydropower System (FCRPS) posed jeopardy to this ESU. To mitigate for the impacts of the dams, the FCRPS Biological Opinion issued by NMFS, emphasized improving spawning and juvenile rearing habitat in the tributaries to achieve recovery of the population.

Obesity is typically defined using body mass index (BMI) and its established cut-off. However, some studies have highlighted the importance of developing racial/ethnic-specific classifications of obesity that reflect different body compositions and fat distributions. Using National Health and Nutrition Examination Survey (NHANES) data and Random Forest classification, this paper attempts to identify important body measures and cut-offs for predicting obesity-related health risks among White, Hispanic and Black male populations in the U.S. In particular, this paper compares the performance of three Random Forest-based methods for dealing with class imbalance: weighted Random Forest (WRF), Random Forest with down-sampling (DS), and Random …
