The UC Davis Campus Travel Survey is an annual survey led by Transportation Services (TS)—formerly known as Transportation and Parking Services (TAPS)—and the National Center for Sustainable Transportation, part of the Institute of Transportation Studies at UC Davis. It collects a rich set of data about travel to the UC Davis campus, demographics, and attitudes toward travel.

The 2020-2021 survey collected data from 3,291 people affiliated with UC Davis about their travel to campus during a single week in October 2020. It used a stratified random sampling method with the intent to gather a representative sample of the campus population. About 18 percent of those invited responded to this year’s survey. For the statistics presented throughout this report, we weight the responses by campus role (freshman, sophomore, junior, senior, Master’s, PhD, faculty, and staff) and gender so that the proportion of respondents in each group reflects their representation in the campus population.

The 2021–22 survey collected data from 4,265 people affiliated with UC Davis about their travel to campus during a single week in October 2021. It used a stratified random sampling method with the intent to gather a representative sample of the campus population. About 21 percent of those invited responded to this year’s survey.

This dissertation work studies the effects of climate-driven flood and wildfire events throughout the American West, with a particular focus on the 2018 Camp Fire in Paradise, California. It brings together an interdisciplinary literature primarily from the fields of hazards geography, economics, planning, and environmental management in order to better understand the economic and social factors associated with recovery from climate-driven disasters. The flood component of this work draws on established theories around price discounting and flood awareness and tests them empirically across three case study counties in the United States. The fire component of this dissertation uses household-level consumer data to map population displacement in the wake of a major wildfire disaster. It also contributes by sharing the first comprehensive survey of wildfire survivors to better understand relocation desires and preferences, adding to a disaster displacement literature that has up to now neglected the category of wildfire hazards.Findings suggest that in regard to flooding, real-estate markets continue to behave different across contexts based on the perception of the flood event as expected or a “freak event.” In the context of wildfire displacement and particularly the case of the 2018 wildfire, the disaster caused a diaspora of thousands of households to relocate across the United States. Social factors were found to be correlated with relocation and relocation distance, with older and wealthier households relocating farther from the fire footprint. Survey findings from this population revealed that above 40% of displaced residents would not prefer to return to the fire-affected area even under “ideal circumstances,” and that measures of place attachment and risk perception supplement social factors as predictive of relocation distance. Taken together, analysis of these wildfire survivors suggests that local and regional planners should think regionally about post-disaster housing and recovery needs. It also spotlights the role that housing affordability plays in hazard vulnerability in California, where the populations that inhabit wildlands tend to be highly socially stratified between those who choose to live in exurban forested environments as a preference, versus those marginalized to these areas by virtue of housing affordability. Future research should continue to focus on the experiences of climate-driven disaster survivors, and interrogate the root causes of vulnerability these hazards.

Wild pigs cause around $1 billion of damage to agriculture in the United States each year — foraging on crops, breaking branches and vines, and damaging irrigation lines and fences — but little is known about how and when they access agricultural fields. We used wildlife camera traps to document and describe wild pig access to two fenced southern San Joaquin Valley farms. Pigs breached fences around agricultural fields, especially during the harvest period when crops were ripe, and almost exclusively at night, outside of the regulated, daytime recreational pig hunting period. GPS data from an adult boar revealed that pigs may travel long distances from wildlands to reach crops. The results of our case study suggest that increasing monitoring and maintenance of fences during the harvest season and removing pigs that have learned to access farms may help reduce pig damage to agricultural fields. The results also suggest a formal scientific investigation of risk factors and strategies to reduce wild pig damage is warranted.

Introduction: Over the past decade, medical students have witnessed a decline in the opportunities to perform technical skills during their clinical years. Ultrasound-guided central venous access (USG-CVA) is a critical procedure commonly performed by emergency medicine, anesthesia, and general surgery residents, often during their first month of residency. However, the acquisition of skills required to safely perform this procedure is often deficient upon graduation from medical school. To ameliorate this lack of technical proficiency, ultrasound simulation models have been introduced into undergraduate medical education to train venous access skills. Criticisms of simulation models are the innate lack of realistic tactile qualities, as well as the lack of anatomical variances when compared to living patients. The purpose of our investigation was to design and evaluate a life-like and reproducible training model for USG-CVA using a fresh cadaver.

Methods: This was a cross-sectional study at an urban academic medical center. An 18-point procedural knowledge tool and an 18-point procedural skill evaluation tool were administered during a cadaver lab at the beginning and end of the surgical clerkship. During the fresh cadaver lab, procedure naïve third-year medical students were trained on how to perform ultrasound-guided central venous access of the femoral and internal jugular vessels. Preparation of the fresh cadaver model involved placement of a thin-walled latex tubing in the anatomic location of the femoral and internal jugular vein respectively.

Results: Fifty-six third-year medical students participated in this study during their surgical clerkship. The fresh cadaver model provided high quality and lifelike ultrasound images despite numerous cannulation attempts. Technical skill scores improved from an average score of 3 to 12 (p<0.001) and procedural knowledge scores improved from an average score of 4 to 8 (p<0.001).

Conclusion: The use of this novel cadaver model prevented extravasation of fluid, maintained ultrasound-imaging quality, and proved to be an effective educational model allowing third-year medical students to improve and maintain their technical skills.
