Dear Members of the USC Community:

It is my pleasure to welcome you to USC’s 18th Annual Undergraduate Symposium for Scholarly and Creative Work. The Symposium is designed to provide USC undergraduates with the unique opportunity to exhibit and share examples of their significant research, scholarly and creative work with the university community. Although the Symposium is modeled on a professional conference poster session, students may exhibit their work in a variety of ways, such as through posters, art exhibits, and electronic media. All undergraduates are encouraged to participate. An award ceremony recognizing the most outstanding works will take place at the end of the Symposium and includes First Prize awards of $1000 and Second Prize awards of $500 in each of the following categories.

 Arts  Humanities  Social Sciences  Life Sciences  Physical Sciences, Math & Engineering

A panel of distinguished faculty will judge submissions in each category. After the judging, you are cordially invited to attend the Award Ceremony in Town & Gown at 6:00 p.m. where the winners will be announced.

We hope you enjoy USC’s Undergraduate Symposium, which promises to be a highlight of the semester this year and in many years to come.

Sincerely,

Michael Quick Provost and Senior Vice President for Academic Affairs

The USC Undergraduate Symposium for Creative and Scholarly Work provides undergraduates with the unique opportunity to exhibit and share examples of their

significant research and creativity with the university community. This year, we have

received 155 submissions with participation from nearly 210 students. Students present

work in a variety of ways, such as through poster/panel sessions, art exhibits, and

electronic media. All undergraduates are encouraged to participate. For some students, the symposium serves as a culmination of work they have produced in partial fulfillment of a senior honors project, or a research project with faculty, both individually and as part of a program.

ACKNOWLEDGEMENTS

On behalf of the Office of Undergraduate Programs and the Office of the Provost, we graciously thank USC faculty and graduate judges for volunteering their time. The success of the undergraduate symposium is largely due to the contribution of their expertise in the judging process. We would like to give special thanks to the USC

Helenes and the for their faithful service. Also, we would like to give a warm thanks to the faculty advisors who have sponsored students in this year’s

Symposium. Your dedication to embrace teaching through inquiry-based learning has

made this event as successful as it has been. And finally, we would like to express our

gratitude to the USC Schwarzenegger Institute for State and Global Policy for their time,

effort and commitment to this extraordinary event.

THANK YOU!!!

There is a clear partitioning of resources by these mammals. Foxes are opportunistic generalists, and both deer and bison are more specialized.

Further data was collected by interviewing the offspring of those with dementia in order to detail each participant’s disease symptomology and progression, as well as to update the family tree. Additionally information was collected also collected pertinent to possible environmental risk factors, including the participant’s general personal history, residential history, and exposure to stressful environmental and life events.

The findings of this survey suggest significant variations in disease development even within a single family, suggesting notable external factors in determining AD symptomology. The hypothesis that exposures related to the pineapple industry might explain the cluster was generally not supported. The hypothesis that the family carries a gene predisposing to AD cannot be definitively addressed in the absence of DNA testing, although given age of onset, it is unlikely that the family is affected by one of the known causative genes. A more likely explanation is that the family carries a genetic predisposition that increases individuals’ vulnerability to external variables that may affect brain health in later age. §§§§
