More than 375 graduate and undergraduate SDSU students across 80 undergraduate majors, and disciplines will showcase their original research, scholarships, projects on 3/7 and 3/8 in Love Library.
This is the 7th year that SDSU’s University Research Council’s Student Research Committee has held the campus-wide event. All current SDSU students from every major and program are invited to present their research or scholarship at the event.
The student Research Symposium is a two-day event to recognize the outstanding scholarly accomplishments of SDSU students. The SRS provides a public forum where SDSU students present their research, scholarship, or creative activities. The event is completely open to the public. Attendees can choose to listen to 10 minute presentations on a variety of topics grouped in themes that include “Evolutionary Biology," "Research in Biotechnology," "Social Justice Themes in the Arts," "Philosophy and Ethics” and “Sustainability” among others. Attendees may enjoy interacting with SDSU faculty, students, and staff while watching presentations like, “Something Old, Something New, Something Swimming in the Blue: A Total Evidence Phylogenetic Analysis of an Extinct Pinniped” or “White Privilege, White Guilt, at the Same Time: The Social Consciousness of Macklemore.”
This symposium represents a chance for the community to see the kind of fascinating and high level work that SDSU students and faculty are collaborating on. Presentations, oral or poster, are organized by academic disciplines with divisions for undergraduate, master’s, and doctoral students. Ten presidential awards ($500) will be made to recognize outstanding achievement in original scholarship. These graduate and undergraduate students will go on to represent SDSU at the CSU Student Research Competition in May 2014. Student presenters will have the opportunity to win other cash awards for recognition of excellence in different categories.
The Student Research Symposium is made possible through the generous support of the President’s Leadership Fund, Aztec Parents Fund, Academic Deans, Aztec Shops, Division of Undergraduate Studies, Graduate and Research Affairs, Office of the Provost, Honors Council, SDSU Research Foundation, University Advancement and Instructional Technology Services.

We have received many amazing gifts during the past year – beginning with the Edward Marsh Golden Age of Science Fiction collection. Here are three stories about additional exciting donations that enrich learning opportunities for our students and faculty.
Librarians keep on giving
Recently retired librarians, Anne Turhollow and Michael Perkins donated $50,000 to endow a Library fund for expenses associated with professional development or research to benefit library operations. Their generosity and love for the Library, as well as their understanding of budget procedures, are reflected in this wonderful gift. Their fund will be used for training costs, guest lecturer and focus group moderator fees, software and incentives for research projects, and will even allow us to provide refreshments -- something the Library had little or no funding for in the past.
We are deeply touched and grateful that after contributing nearly 60 years of service between them, Anne and Mike continue to give to the Library.
Anonymous couple fund library travel expenses and more ...
A $200,000 pledge made by an anonymous couple will fund professional development opportunities (including travel) for Library faculty and staff. Their generosity will also support Library instruction activities and the purchase of materials.
This couple has strong ties to the Library and decided to make a bequest to the Library. Working with SDSU's Planned Giving department, they created an estate gift for the Library and stipulated how their endowment will support Library operations. This enduring legacy demonstrates their connection to the SDSU Library and provides a perpetual stream of benefits.
Old Globe Digitization: Ecke gift unveils a lost collection
Long time Library supporter, Elisabeth (Jinx) Ecke has made a $15,000 multi-year pledge towards the processing of the Old Globe Theatre collection. The Ecke family has a long-standing tradition of generosity in San Diego and to the Library; Jinx is a former member of the Friends of the Library Board. Development Director Alan Andrade guided the process which brought together the Ecke's legacy of philanthropy and Jinx's love of the theater.
The extensive Old Globe archives were gifted to SDSU beginning in 1984, but have been largely unprocessed and therefore hidden for most of that time. In 2010, fellow board member Pam Wagner generously supported the digitization of the Old Globe Theatre Photograph Collection, and Darlene Davies supported the processing of her related archives, The Darlene Gould Davies Old Globe Theater Special Collection. This was a first step in bringing to light the Library's hidden treasure of materials on San Diego's theater history. Now Jinx Ecke's gift will accelerate processing of these materials, providing rich resources for scholars.

As a part of the campus Arts Visibility Project from the University’s Strategic Plan, the Library is collaborating with the College of Professional Studies and Fine Arts to integrate visual and performance arts in the Library.
“Art Under The Dome” will begin this semester with a series of short performances. The arts can inspire creativity and enhance the student learning experience and the Library is contributing to student success through this collaboration. Watch for performances of music ensembles, theater, and art exhibits.
The first of this series will occur in the Dome, this Friday, November 8th, at 12:15pm. Come and listen to the performances of two SDSU student chamber music ensembles—a string quintet and harp and violin duo--sponsored by the School of Music and Dance. Each performance will last approx. 10 minutes and will give us just a small sample of the music quality that exists here on our campus. These groups will be performing pieces they plan to perform in concert later in the semester, so you will have another opportunity to hear our talented students. Please stop by and enjoy this wonderful listening experience.

A person’s life can be compared to a book: It’s a story that unfolds as each page is turned, with major events, revelations, and transitions occurring at the end of a chapter. Two long-time faculty of the San Diego State University Library are completing their decades-long career chapters at the end of June 2013 and beginning a new chapter in their lives: retirement.
Anne Turhollow received her bachelor of science degree from Loyola Marymount, a master of biological science degree from Stanford, and her master of library and information science degree from the University of California, Berkeley. Anne was hired by SDSU as a science reference librarian in 1982, initially serving the departments of biology and mathematics. Over the years, the biological science, mathematics and statistics, chemistry and biochemistry, and the School of Exercise and Nutritional Sciences were also placed under her guidance.
Anne has served as the coordinator for the Computer Search Service and later Electronic Reference Services. She helped to implement the library’s CD-ROM network, the online catalog, the Website, and other projects. Anne has headed both the library’s Science Division and its Reference Services Division. She ends her SDSU career on a high note: she has served as interim associate dean since 2011.
Robert Carande received his master of library science degree in 1985 from the State University of New York at Buffalo, which is where he also received a bachelor of arts degree in philosophy. He also holds a master of arts degree in philosophy from SUNY Stony Brook. Robert moved to San Diego in 1986 and initially found employment with Sociological Abstracts, Chula Vista Public Library, and General Dynamics. A year later, he accepted a position as science librarian at San Diego State with subject responsibilities in physics and astronomy. Over time, Robert added geology, engineering, art, philosophy, and religious studies, to name a few, under his aegis, and he served as head of the library’s Sciences Division, a responsibility he later shared with Anne Turhollow. During his time at SDSU, Robert published a dozen peer-reviewed articles and two books: Automation in Reference Services and Information Resources in Virtual Reality.
Fortunately, Robert will return to the library on a part-time basis beginning August 19 as part of the Faculty Early Retirement Program (FERP), which will enable him to work approximately six months per year. This schedule will allow him plenty of time to indulge in his passion for photography and art and “finally find the time to learn Photoshop.”

Testing the Role of Physical Acceptance in the Exercise and Self-Esteem Model in College Students
Kayli Dalton, Exercise Physiology & Nutritional Sciences (Masters Student)
Objective: To examine the proposed mediating relationships of the exercise and self-esteem model (EXSEM) over time and the role of physical acceptance in the college population.
Participants: Eight-five freshmen undergraduate male (n = 25; M age = 18.0 years; SD = 0.5) and female (n = 60; M age = 17.8 years; SD = 0.4) students.
Methods: Participants completed valid and reliable self-report measures of exercise self-efficacy, physical competence, physical acceptance, and global self-esteem pre and-post an 8-week time period.
Results: Regression analyses supported the proposed mediating relationships of the EXSEM. An additional relationship was found to exist where physical acceptance mediated the influence of exercise self-efficacy on global self-esteem. Together, change in exercise self-efficacy and physical acceptance explained 23% of the variability in global
self-esteem. Conclusions: These findings support the inclusion of physical acceptance and its importance in the exercise and self esteem relationship in college students. Additional relationships than those first proposed within the EXSEM were found. Further study is needed to examine these additional relationships, as well as how exercise contributes to improvement in physical self-perceptions, especially in the college-aged population.
Is X-ray Florescence Imaging, a Valid Measure in Examining Differences in the Metal Concentrations of Postmortem and Resected Brain Tissue?
Laura Frutos, Psychology (Undergraduate)
The human brain is abundant in metals, which are essential for healthy cognitive function. Changes to the levels of metals may result in neurological conditions as seen in various disruptions to the central nervous system. In this project, Synchrotron x-ray fluorescence (SXRF) imaging was used to examine the metal concentration of postmortem and surgically resected brain tissue. The postmortem tissue was donated by individuals with Williams Syndrome (WS) and the resected tissue samples were obtained from individuals undergoing surgical resections to control pharmacoresistant epilepsy. SXRF imaging was conducted at the Stanford Synchrotron Radiation Lightsource. The technique has previously been used to study other human brain conditions including Parkinson’s and Alzheimer disease. This is the first study to examine WS and resected epilepsy tissue. We have previously shown that SXRF is a sufficiently sensitive technique to distinguish concentrations and co-localization of metals in brain structures. However, the method is still under development and additional studies are necessary to further validate its usage as a quantitative method that can be applied to a larger spectrum of brain conditions and tissue preparations. To this end, we analyzed
the concentration and distribution of metals in tissue samples over multiple trials to test whether the detection of metal levels is altered as a result of repeated exposure to the high energy x-rays used in the technique. We hypothesized that there will be no significant difference between the concentration of metals during trial runs when examined over a short period of time. Qualitative review of brain scans showed no marked differences and the quantification of endogenous metals using standards calibration is under investigation. The additional validation of this technique will enable us to better describe potential differences in metal concentrations in brain structures (e.g., frontal lobe, amygdala, hippocampus) associated with Williams Syndrome and epilepsy. The results could aid in identifying novel markers of pathology and provide insight into the relation between metals and brain structures in cognitive function. The research also aims at finding alternative, less invasive, and greener forms of identifying etiology of neurological conditions.
You can look but don’t touch: the real-time dynamics between infant visual and haptic behavior
Kristi Hendrickson, Speech, Language, and Hearing
The application of looking- and reaching-based measures as proxies for underlying cognitive abilities has a rich history in infant development research, and perhaps none more so than studies of early vocabulary comprehension. Both visual and haptic measures have long-term predictive value, though it remains unclear whether they are analogous and substitutable measures of lexical knowledge (Charles & Rivera, 2009). Additionally those who implement haptic methods are confronted with the challenge of interpreting the difference, if one exists, between representations that drive incorrect versus absent responses. Analyzing looking behavior concurrently with haptic response creates a ground for
determining differences between these two response types.
We investigated the real-time dynamics between two measures of word comprehension: one visually-based (Fernald et al. 2001, 2008), and one haptically-based (Friend et al., 2003, 2008, 2012). Fifty 16-18-month-old infants were seated in front of a touch sensitive screen and prompted to touch one of two images (target). Videos of infants’ looking and haptic responses were synced and coded frame-by-frame. Visual reaction time was operationalized as mean latency to shift to the target image. Haptic response was operationalized as number of target touches.
Reaction time significantly predicted haptic response, F(1,49) = 7.299, p < .009 accounting for ~13% of the variance. To further investigate this relation, we divided trials into three haptic types (target, distractor, and no touch). There was a significant effect of trial type, F(2,43) = 11.98, p < .001 such that mean reaction time for no touch trials (M = 1134.5, SD = 465.3) was significantly greater than for target (M = 742.8, SD = 324.0) and distractor touch trials (M = 903.1, SD = 309.6). However reaction times for target and distractor touch trials did not differ significantly.
In the current study we found that visual reaction time and haptic response are significantly related. Moreover, reaction time changes as a function of where and whether infants execute a haptic response suggesting that distractor touches reflect partial knowledge, whereas failure to touch appears to reflect an absence of knowledge. This research will help bridge the gap between different assessment approaches to measuring early language.
Synthesis and Toxicity of Silver Nanoparticles with Different Capping Agents and Shapes
Alyssa Deline, Chemistry (Undergraduate)
Silver nanoparticles (AgNPs) are primarily exploited for their antimicrobial properties, and their increased use in consumer products has raised serious concerns over their potential impact to sensitive bacteria commonly found in wastewater treatment plants (WWTPs). AgNPs contain a capping agent (e.g. citrate, polyvinyl-pyrrolidone (PVP) or tannic acid) to prevent aggregation and come in a variety of shapes (e.g. spherical to triangular platelet). Each of these factors may greatly influence the toxicity of the AgNPs. We investigated the toxicity of AgNPs synthesized with various capping agents and shapes to Nitrosomonas europaea, a model ammonia oxidizing bacteria commonly found in WWTPs that is responsible for the conversion of ammonia (NH3) to nitrite (NO2- ).
Spherical AgNPs were synthesized through the reduction of silver nitrate with sodium borohydride in the presence of a capping agent. To create triangular shaped AgNPs, citrate-capped AgNPs were exposed to either a blue light (420 nm), green light (522 nm), or red light (690 nm) for a period of two weeks with daily addition of additional citrate. The size and shape of AgNPs were confirmed with transmission electron microscopy (TEM). The influence of AgNP capping agents (e.g. citrate, PVP, and tannic acid), and shape (e.g. spherical vs. triangular) on the toxicity to N. europaea was determined by monitoring their nitrification activity during 3-hour batch bioreactor experiments. During these experiments, N. europaea was exposed to the various AgNPs and the NO2- production was measured colorimetrically every 45 minutes over the course of 3-hours.
Synthesis of triangular silver platelets ranging from 50-300 nm and pentagonal AgNPs ranging from 40-60nm were confirmed by TEM imaging after two weeks of exposure to red light (690 nm) and blue light (420 nm), respectively. Green light (522 nm) did not elicit noticeable changes in shape when compared to spherical AgNPs not exposed to light. The results from the toxicity experiments suggest that the capping agents (i.e. citrate, PVP and tannic acid) did not influence the toxicity of the AgNPs towards N. europaea. Further work is needed to size fractionate and purify the triangular AgNPs for future toxicity studies.
