An inside look at compelling research being conducted by SSU faculty and their students is on view at the 18th Annual Faculty Research Exposition from 3:30-5:30 p.m. on Wednesday, April 2 in the Student Center Ballroom B and C.
This year's participants are involved in projects that provide a wide-ranging look at research and grant activity that is crucial to an active and productive SSU community. Student involvement in research activities is also a key element to any undergraduate experience.
Faculty and staff members throughout the campus are involved in vital, creative and significant projects, funded through CSU, state, federal and private sources. This annual event provides an opportunity for researchers to share their work with the rest of the campus community.
The event is hosted annually by the Office of Research and Sponsored Programs (ORSP) and Faculty Subcommittee on Sponsored Programs (FSSP). It is supported by John and Katharyn Crabbe through their donations to the John and Katharyn Crabbe Faculty Development Fund.
Projects on display by faculty, in their own words, include:
Collaborative Autism Training & Support Program (CATS)
Lorna Catford -- Psychology
Stacey Cranfil, Robert Wyckoff (SSU Students)
Since 2005, the CATS Program has grown from a one-semester course where 20 students provided 1,000 hours of free direct interventions and support to 20 children on the autism spectrum, to an award-winning program with 36 community partners and a 2-semester Service-Learning course. This year 86 students are providing almost 4,500 hours to about 86 children. Students from many majors participate and over 50% become employed in the field. They also take on leadership roles in the program, which is supported by Instructionally Related Activity funding.
Mapping of San Francisco Bay Area Land Cover with Hyperspectral imagery
Matthew Clark -- Geography & Global Studies
Land-cover mapping over broad spatial scales is typically accomplished by automated processing of multi-spectral (i.e., a few spectral regions) images from existing satellites. NASA has plans to develop a "hyperspectral" sensor, called HyspIRI, that will provide imagery with measurements of energy from hundreds of spectral wavelengths. Dr. Clark will present his NASA-funded research that uses simulated HyspIRI images for improved mapping of land cover in the San Francisco Bay Area.
Education and Public Outreach at Sonoma State University
Lynn Cominsky - Physics & Astronomy
Dr. Kevin McLin, Aurore Simonnet, Kevin John, Dr. Carolyn Peruta, Laura Chase
SSU's Education and Public Outreach group supports four NASA high-energy astrophysics missions: the Fermi Gamma-ray Space Telescope, the Swift Gamma-ray Burst Explorer , the XMM-Newton mission and NuSTAR. These missions detect x-ray or gamma-ray light, observing the most exotic and extreme objects in the Universe: blazing galaxies, intense stellar explosions and super-massive black holes. Our mission is to develop exciting formal and informal educational materials to inspire students in grades 5-14 to pursue STEM careers, to train teachers nation-wide in the classroom use of these materials, and to enhance science literacy for the general public. Our newest project, "Learning by Making" has been funded by the Department of Education and is being done in collaboration with SSU's Early Academic Outreach program, led by Susan Wandling.
Developing A High-Precision Real-Time Movement Monitoring System for Treatment Evaluation of Parkinson Disease
Farid Farahmand -- Engineering Science
Jorge Cabrera (Graduate, Engineering), Janene Grippi (Undergraduate, Kinesiology), Campbell Smith (Undergraduate, Engineering)
In this work, we report on our progress in studying the tremor model to track the advancement of the Parkinson's disease (PD). We have developed a wireless wearable multi-sensor prototype that can integrate measurement of movement disorders, such as tremor, with physiological parameters (e.g., body temperature, pulse, and blood pressure) of the patient. Thus, through a network of multiple wearable sensors we can quantify hand tremor in terms of its severity, patterns, and behavior during ON and OFF medication periods under free-living environment. We believe quantifying PD attributes can result in optimizing patient-specific therapy and consequently, improvement of patient care and quality of life.
The Río Verde Early Agricultural Landscape Project (Project RVEAL)
Michelle Goman -- Geography
Grace Lock, Daniel Viera, Nick Darst (2013), Carissa Green (2012), Jeremey Sullivan (2013), visiting Scholar Victor Salazar
Paleoenvironmental and geoarchaeological research in the Lower Río Verde Valley, Oaxaca, indicates that humans were directly affected by significant environmental changes that caused shifts in depositional dynamics which affected flood plain and coastal landforms. Sediment cores collected from a spatially intense network of lacustrine sites within the floodplain and coastal region are enhancing our understanding of human ecology. These cores were analyzed for a suite of biological proxies, including pollen, charcoal, and carbon isotopes, which provide information on vegetation change. The Paleoenvironmental data coupled with the archaeological record offer insights into human land use dynamics over the past 3000 years.
Co-teaching: A Promising Reform in Teacher Education
Karen Grady - Curriculum Studies and Secondary Education
This qualitative study investigated the implementation of a co-teaching model of student teaching in which teacher candidates teamed with their school-based mentor teachers, doing far less solo teaching than often occurs. The extended apprenticeship stands in stark contrast to the "sink or swim" model of student teaching widely implemented for the past 80 years in teacher education. The results of the study indicate that teacher candidates found the experience worthwhile, inspiring, and effective in their development as beginning teachers. Limited data from secondary students also point to how co-teaching positively contributes to their learning.
Systems Theory and Practice
Debora Hammond - Hutchins School of Liberal Studies - Organizational Development
Building on 20 years of research into the history, philosophy and social implications of systems thinking, my research during my Fall 2013 sabbatical focused on exploring the various lineages of applied systems theory. The thesis of my dissertation, later published as The Science of Synthesis, that systems orientations support more inclusive, participatory and collaborative approaches to decision making in organizations, provided the focus for most of my research in the intervening years. My current research is focused on the models and methodologies used in applied systems theory.
Applied Ethological Research in the Sonoma State University Primate Ethology Research Lab: Improving Exotic Animal Welfare and Enhancing Student Academic Experiences
Karin Enstam Jaffe -- Anthropology
Applied ethology (aka: animal behavior) is often associated with improving the health, safety and well-being of companion, laboratory and/or farm animals. However, ethological research can also help zoos and aquariums improve the welfare and management of captive exotic animals. In Fall 2012, I received a Faculty Mini-Grant to support the development of research collaborations with the San Francisco Zoo and Safari West and expansion of student participation in animal behavior research. My poster will describe 1) the research projects undertaken by the SSUPER Lab since receiving the Mini-Grant, 2) the nature of student involvement in these projects, and 3) the incorporation of applied ethology into the anthropology curriculum.
Thinking like a Social Scientist: An Experimental Assessment of the School of Social Sciences Sophomore Seminar (part of the Sophomore Year Experience Program)
Michelle Jolly -- History
Laura Watt, David McCuan, Jeff Baldwin, Paula Hammett, Heather Smith (SSU Faculty)
In Fall 2013, the School of Social Sciences piloted SSCI 299, "How to Think Like a Social Scientist," the core academic component of a broader Sophomore Year Experience (SYE) program. As part of the pilot, students, who were randomly assigned either to a waitlist or one of 3 seminars, answered questions about their SSU experience and social science knowledge and also submitted writing samples. Seminar participation influenced students' knowledge, performance and interest in staying at SSU in both expected and unexpected ways.
SAR Reduction in Telemedicine Systems
Haider Khaleel -- Engineering Science
Telemedicine is becoming increasingly utilized by health care providers due to the growing demand for remote monitoring of human vital signs. Telemedicine applications include but not limited to monitoring of seniors, recovery tracking of patients, monitoring the health parameters of astronauts and athletes, and E-psychiatry. In this project, a flexible, compact antenna system intended for telemedicine applications is proposed. The design is based on a printed monopole antenna operating in the Industrial, Scientific, and Medical (ISM) 2.45 GHz band integrated with a miniaturized Artificial Magnetic Conductor (AMC) ground plane. The AMC ground plane is utilized to isolate the user's body from undesired electromagnetic radiation in addition to minimizing the antenna's impedance mismatch caused by the proximity to human tissues.
Reference in Perpetual Beta: The Sonoma State University Experience
Nicole Lawson and Megan Kinney -- University Library
Over the past several years reference service at the SSU Library has transitioned from a traditional reference desk, to co-locating with circulation, to what is now an on-call/roving service. Faced with staffing multiple service points and too few people to support them, the Public Services Librarian began an assessment of existing workflows and two pilot studies in Spring 2012. Based on the results of the pilots and input from Library faculty and staff, the service became on-call in Fall 2012 and roving became more robust in Fall 2013. This tiered public services system is more seamless and creates a more flexible workflow. Assistance is always available, reference interactions have become more satisfying, and patrons receive help at the moment it is needed.
Determination of the IC50s for Wild-Type and Fragmented Antimicrobial Peptides
Jennifer Whiles Lillig -- Chemistry
Agya Karki, Kelsey Goldbeck (SSU Students)
Class II a bacteriocins are known for their ability to inhibit growth of Listeria monocytogenes. However, it is unknown which domains of the peptide are important in its activity. Therefore, to study the role of each domain, our lab has measured toxicity of the wild type, N-terminal, and C-terminal domains of pisciocin V1a from Carnobacteria piscicola. The N-terminus of V1a was synthesized using solid phase peptide synthesis. De-protection of each amino acid was visualized as a decrease in absorbance at 290nm. Peptide was purified through HPLC which resulted in a peak at 35 minutes. Toxicity assays showed a decrease in OD600nm indicating bacteriocin activity. The IC50 values were (greatest to least): 0.02µM (wild-type), 10µM (C-term), and 44.69µM (N-term). This is the first time a C-terminal fragment has shown activity.
A Low-Cost PCB Fabrication Process
Jack Ou -- Engineering Science
Alberto Maldonado and Chio Saephan (Engineering Science students)
This project investigates the resolution of a low-cost printed circuit board (PCB) fabrication process. A set of frequently used footprints is fabricated on a PCB and examined under a digital microscope. The results indicate that using the process described in this paper, a thin wire with a 0.38 mm (14.96 mils) width can be fabricated. The process described in this paper is useful for educators who wish to fabricate a fine structure on a PCB, but do not have access to a milling machine. It is also useful for researchers who wish to quickly build an inexpensive prototype before sending out the final design to a commercial venue.
Measurement of Organic Pollutants on the SSU Campus
Mark Perri -- Chemistry
Ben Diamond, Michael Haggmark, Erin Ballantyne (SSU Students)
Solid Phase Microextraction (SPME) is a relatively new technique that is used to separate organic compounds from water so that they can be analyzed by gas chromatography / mass spectroscopy. We have analyzed samples from various parts of campus and identified organic compounds, including organophosphate pesticides. We are currently working on quantifying the organic pesticides.
Interpretive Research Design: Model for Community-Based Bioarchaeology
Adrian Praetzellis -- Anthropology and ASC
Whitney McClellan, Anthropological Studies Center (ASC)
Human remains and associated artifacts of CA-MRN-27 have been inventoried in compliance with NAGPRA. While the individuals and artifacts await reburial by the Federated Indians of Graton Rancheria (FIGR), they present an opportunity to implement community-based bioarchaeological research in conjunction with the tribe. The development of this research model will shift the emphasis of study away from FIGR as research subjects, to instead working with the tribe as equal partners. This study aims to collaboratively create a research design, methodological criteria and final interpretations that are relevant to the indigenous, archaeological, and bioarchaeological communities involved while adhering to NAGPRA guidelines.
Cultural Resources Research at Fairfield Osborn Preserve
Adrian Praetzellis -- Anthropology and ASC
Kyle Rabellino - ASC
For 40 years the 411-acre Fairfield Osborn Preserve (FOP) has been the location for various types of scientific studies, including botanical, hydrologic, climatic, and zoological. Recently, the FOP has been the subject of archaeological and historical investigation in the form of a cultural resources inventory and oral history project. We will highlight FOP's environmental setting, prehistoric and historic-era cultural contexts and resources, and our research methods and results. The goal is to create a cultural resources management plan for the FOP.
Lands End Public Interpretation
Adrian Praetzellis -- Anthropology and ASC
Sandra Massey, Dana Shew - ASC
ASC conducted archaeological excavations at Merrie Way, the site of a historic amusement park, prior to the construction of Lands End Visitor's Center. Lands End is an appropriately literal and figurative designation for San Francisco's westernmost edge. Situated at the mouth of the vast Pacific Ocean, Lands End is a uniquely remote and mysterious place that has drawn people to its shores for centuries. Lands End stretches from China Beach to Ocean Beach and includes iconic places such as the Cliff House and Sutro Baths ruins. For the Center's opening, ASC created two public products: Lands End Times--a newspaper--and Vestiges of Lands End--a website.
S3: STEPping up STEM at SSU
Jeremy Qualls -- Physics & Astronomy
S3: STEPping Up STEM at SSU is an NSF funded project that uses a three-pronged strategy to increase retention and graduation of STEM students. The primary element of this strategy has been to develop an interdisciplinary STEM First Year Experience program (SCI 120) investigating environmental sustainability in the local watershed. External assessment based on a matched cohort model and propensity score method indicate that SCI 120 students are three times as likely to continue in STEM.
Design and Analysis of Algorithms for Combinatorial Problems
Bala Ravikumar -- Computer Science
Design and analysis of algorithms for combinatorial problems is at the heart of computer science research. In this paper, two natural variations of a fundamental problem (called binary search) will be studied and a new, faster algorithm will be presented. While some advanced calculus and discrete mathematics will be used to develop the solution, we also use a fast search on the computer to find the best way to search when the game reaches the final stage. We also develop lower-bound technique that places a limit on how fast the problem can be solved.
Classification of Supercomputing Applications by Power Consumption
Suzanne Rivoire -- Computer Science
Jolie Nazor, Rachelle Thysell, Jacob Combs, Fabian Santiago, Lowell Olson (SSU Students)
Power consumption in large-scale computing facilities is a major problem. Our goal is to characterize power usage of supercomputing applications in order to improve energy efficiency. We focus on identifying applications by their power consumption patterns, irrespective of their input data and the hardware on which they run. In this work, we summarize 225 power traces taken from 13 supercomputing applications using statistical feature vectors. We show that applications can be identified based on these features with over 90% accuracy, even across hardware platforms. These results indicate that application-specific power management is a promising approach.
Contested Spaces: Islamic Monuments in 20th Century Cordoba, Spain
Jennifer Roberson -- Art History
Cordoba, Spain, was once home to numerous mosques built during its Islamic period (8th - 13th centuries). When Christian leaders took control, all mosques were torn down or converted to churches. By the 20th century, Catholicism was the majority religion and under Francisco Franco the state religion. Following Franco's death in 1975, a new constitution established religious freedom. During this era of change, Cordoba's Islamic monuments became sites of debate. When confronted with a growing Muslim community, an uneasiness with Cordoba's Islamic past emerged. This project examines the controversies that arose in the post-Franco era regarding Cordoba's Islamic monuments.
Assembly and First Light of the KAPAO Adaptive Optics System
Scott Severson -- Physics & Astronomy
Katherine Badham (Physics 2013)
We have built a system to dramatically improve the sharpness of astronomical images at the Table Mountain Observatory one-meter telescope. This technique is called "Adaptive Optics" (AO) and works at the physical limit of our ability to image. The KAPAO project is a collaboration between Sonoma State University, Pomona College, Harvey Mudd College and the California Institute of Technology. We present the design of our completed system and results from student analysis of our early images. This material is based upon work supported by the National Science Foundation.
Growth and Characterization of Al-doped ZnO (AZO) via Electrochemical Deposition: An Exploration of Optoelectronic Applications
Hongtao Shi -- Physics & Astronomy
Stephan Jackowski (SSU Student)
The electrochemical solution approach we used is appealing for the growth of Al-doped ZnO (AZO) because of its low growth temperature, low cost, ease of operation, and good potential for scale-up. Using the facilities in the Keck Microanalysis laboratory, we demonstrated that AZO films can be successfully grown on silicon wafers. The morphology of the samples can change from one dimensional nanometer scaled wires to two dimensional flakey films. Ultraviolet light emission from these samples can be significantly enhanced after certain annealing process. While as-grown ZnO is often an insulator, AZO films could have tunable conductivity for different optoelectronic applications.
Does University Identification Lead to University Engagement? An Experimental Test
Heather Smith -- Psychology
Desiree Ryan, Alexandria Jaurique, Brian Johnson and Jack Hyer (SSU Students)
Are students who feel warmly connected to their university community more motivated to excel in the classroom? To test this question, we randomly assigned 85 university undergraduates to a 2 [low vs. high university identification] x 3 [focus on university competence, sociability or integrity] between subjects experimental design in which participants wrote about a time that they felt connected or not connected with Sonoma State University. Students' willingness to engage in various university activities (presented as part of a separate questionnaire) depended upon the type of university identification that we primed.
Reconstructing the Eocene Nevadaplano using Geochronology and Basin Analysis
Michael Smith -- Geology
Approximately 45 million years ago, the state of Nevada resembled the Andes of western South America, the Earth's second highest mountain range. Since then, this high area has collapsed and spread out into a series of smaller ranges separated by low elevation basins. During the initial phases of this collapse, a large lake (or series of smaller lakes) formed in what is now a very dry desert, similar to Lake Titiqaqa in Bolivia and Peru. The deposits of this lake and the rivers that flowed into it contain important clues about the evolution of the area, and undergraduate researchers from SSU are currently analyzing volcanic ash samples that will assign to them high-resolution age control.

Bulent Sokmen -- Kinesiology
Wesley Martin, Sabrina Hrabe, Lauren Fryer, Kate McFarland, Olivia Colombo, Dang Le, Alyssa Bernat, Sylvia Lewis (SSU Students), and Daniel Grubb (SHIP intern)
This study examines the effects of acute caffeine intake on cycling efficiency through physiological and metabolic responses during intermittent cycling and following time trials in trained males and females. Using a double blind, randomized, crossover experimental design, 8 male and female competitive cyclists completed two experimental trials: one caffeine and one placebo, separated by at least one week. Subjects performed 120 minutes of intermittent cycling on a stationary ergometer, alternating three min at 30% and one min at 100% VO2max, prior to cycling to fatigue at 90% of VO2max. Perceptual, physiological, and metabolic responses were collected at min 0, 30, 60, 90, 120 and at the end of time to fatigue.
Promoting Diversity through Psychological Research Contributions of Undergraduate Researchers
Elisa Velasquez-Andrade -- Psychology
Study 1: Paul Martinez, Lawrence Ricardo, Stephanie Young, Anacarmina Mariategue. Study 2: Peyton Bloemker, tori Bohnet, Rachel Folmer, Cole Goetzl, Selena Gonzalez, Rocky Nash, Ryohei (Leo) Ozawa, Rachel Porter, Blake Ratto, Angela Sierra, Danielle Zimme
This poster describes two studies focused on diversity and implemented by undergraduate students in the psychology department. Study 1, reports the impact of inter-group diversity dialogues on participants' levels of racial and ethnic prejudice. Study 2, identifies racism and micro-aggression experienced by African-American students and their coping mechanisms. We report the impact of racism across racial groups, effects on campus climate, and quality of education. We will distribute a report with recommendations to address issues of racism on campus. An Action Research approach contributes to the SSU diversity mission and provides an atmosphere for undergraduate students to develop research skills.
