Seasonality is defined as a change in mood and behavior with the seasons. Research shows there is a possible connection between vitamin D levels and mood (Murphy & Wagner, 2008; Lansdowne & Provost, 1998). Given that vitamin D is produced when skin is exposed to sunlight and varies with sun...

Seasonality is defined as a change in mood and behavior with the seasons. Research shows there is a possible connection between vitamin D levels and mood (Murphy & Wagner, 2008; Lansdowne & Provost, 1998). Given that vitamin D is produced when skin is exposed to sunlight and varies with sun...
A distinguishing feature of elite cross-country (xc) skiers is their superlative upper body power (UBP). Race points/rankings are highly correlated to UBP, thus it appears that UIBP training is an integral component to the success of xc ski racers. Recently, roller board training was shown to be superior for improving...
The purpose of this capstone is to provide a reassessment of the emergence of biophilia in interpretive programs conducted in California State Parks. More specifically, this project examines what effect natural resource interpretive programming has on the emergence of biophilia practices and if participants are more likely to be more...
The High Plains Aquifer, a natural resource critical to the United States economic, energy and food security, faces significant sustainability challenges in the coming years. This case study aims to identify the main causes and consequences of unsustainable use of the High Plains Aquifer. The agriculture industry plays the largest...
Through comparison and analysis of selected holidays in countries with significantly different features (Kyrgyzstan, Russia, and the United States), this study aims to gauge the impact of holiday celebrations in influencing cultural values in those countries studied. K. Zygulski’s classification system for holidays was applied to divide the holidays of...

Contemporary fire effects are raising concerns about the resistance and resilience of dry mixed-conifer forests to large wildfires. Fire refugia – unburned or low-severity patches within fire perimeters – are understudied components of post-fire mosaics that may be key drivers of forest recovery following high-severity fire. Little is known about...
The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) times periodic signals from pulsars as a method of detecting gravitational waves. NANOGrav detects waves emitted in the nanohertz frequency range, a range lower than those previously explored by other organizations. This allows for the study of rarely observed sources such...
