2014 Abstracts

Ty Martin, Utah Valley University Social and Behavioral Sciences The purpose of this study was to explore the marital and personal life outcome of couples who either had in-law troubles or did not. Using Gottman’s (1999) core principles, this study explored the complex challenges young married couples faced when trying to turn toward their spouse while problematic relationships with their spouse’s parents created a wedge. Data was obtained via a random sample of 3,000 current and 7,000 former UVU students. Of the 11 percent who responded, 488 were in their first marriage. Two types of statistical analysis were used to explore the relationship between the married student’s relationship to their in-laws and other personal and marital factors.

Steven Clements, Utah Valley University Social and Behavioral Sciences The purpose of this study was to test the impact of having been on a dangerous call to EMS employee’s well-being. Two hypotheses were tested: First, suffering psychological symptoms from a dangerous call had no impact on their well-being; and second, suffering physical symptoms from a dangerous call had no impact on their well-being. In 2010, 7,000 state EMS employees were surveyed, yielding 668 completed surveys for this study.

Bryson Pope, Brigham Young University Social and Behavioral Sciences Purpose of the Project:

Chelsea Pineda Davey, Brigham Young University Social and Behavioral Sciences Sense of community on the island of Guernsey is a cross between organic and mechanical solidarity. I argue that this sense of community is built and maintained through the island’s voluntary sector. The charities and volunteers help to preserve Guernsey’s sense of community and hold the society together. As I do this I use Durkheim and Mauss’s theories along with the McMillan/Chavis definition of sense of community to support my findings.

Chantelle Fitting, Brigham Young University Social and Behavioral Sciences Rebelliousness is often the product of an effort to express individualism and is an outlet for uniqueness (Imhoff & Erb, 2009); however, it can have very detrimental consequences. When a person strives to not conform to his or her family’s beliefs and values, familial relationships become strained, and the potential arises for the family to be torn apart. This nonconformity manifests itself through the beliefs a person has and the actions they take that are markedly different from those chosen by family members. The Nonconformist Assessment Scale (NCAS) is a ten question survey that is used to measure an individual’s inclination to rebel against his or her family unit. With the NCAS, we seek to discover indications of early rebelliousness, which are manifested through a person’s deviation from the family in areas such as weekly activities and personal interests. By detecting the seeds of nonconformity that arise in early life within the family, family therapists can intervene before more severe rebelliousness such as illegal activity, abandonment of core family values, or other dangerous behaviors emerge. Cronbach’s Alpha of the NCAS was found to be .7195, giving the test acceptable reliability. The Pearson bivariate correlation indicated that every item except item nine correlated positively with at least seven other items. The items loaded onto a single factor, and the variance explained by this factor was .7019. Thus the NCAS is a good indicator of nonconformity to familial values. However, the domains of actions and beliefs were not discernible as the items loaded only onto a single factor, so further research could be conducted that includes items where these domains are more easily separated from each other.

Joshua Matyi, University of Utah Social and Behavioral Sciences The Neural Efficiency Hypothesis (NEH) states that individuals with higher measured intelligence exhibit less neural activation on relatively simple tasks compared to those with lower intelligence (Haier et al., 1988). While the current NEH literature regarding electroencephalography (EEG) primarily focuses on amplitude measures, differences in peak latency relative to task demands could also indicate processing efficiency. The current study examined the relationship between intelligence and event-related EEG amplitudes and latencies during the third of three task conditions, a visual repetition paradigm. Full Scale IQ (FSIQ) scores from the Wechsler Adult Intelligence Scale III (WAIS-III; Wechsler, 1997) were collected on 30 participants, 18 of whom had sufficient numbers of EEG trials for further analysis (FSIQ: M = 111.56, SD = 13.28, range = 91 to 131). During EEG recording, participants were asked to respond to randomized line drawings representing one of three stimulus conditions from the previous two tasks: Repeated stimuli, Once-viewed, and Novel stimuli. Time-frequency analyses were conducted to identify peak phase-locked activity in the theta (4-7 Hz) and alpha (8-12 Hz) bands between 0 and 500 milliseconds post-stimulus. Results demonstrated no significant effects of IQ or stimulus condition on peak theta and alpha amplitudes. However, difference scores between Novel and Once-viewed conditions in peak theta latency showed a strong positive correlation with IQ (r[16] = .712, p < .01). These findings appear consistent with the NEH in suggesting that higher IQ individuals may process previously seen stimuli more efficiently than lower IQ individuals, as evidenced by shorter peak latencies relative to stimulus onset. A direction of future research could involve manipulating visual stimulus complexity, in order to isolate the effects of task complexity on peak latency, and potential interactions with IQ.

Katherine Abarca, Westminster College Social and Behavioral Sciences The Hunger Games series has sold 50 million copies of the three books as of July 2012, has an impressive fandom, and has significant influence on popular culture. One of the many reasons for the success of the series is that its shocking story is set in a society eerily similar to the United States. The fictional country of Panem and its similarities to the United has caused it to gain interest in academia. Utilizing textual analysis, I examine how the fictional country of Panem is similar to present day United States in its inequality between classes and use of mechanisms of control. I also discuss how this cultural artifact affects our understanding of our society and how our society is reflected in the books. This research will expand the limited academic literature analyzing the Hunger Games. In addition, this research will focus on the different mechanisms of control in how they maintain inequalities between classes rather than stopping at analyzing the mechanisms themselves.

Kent Hinkson, Utah Valley University Social and Behavioral Sciences PTSD has become increasingly more concerning to the mental health world over the past few decades. A plethora of events (both acute and chronic) that serve as a triggering moment in the lives of those afflicted by this potentially debilitating condition are beginning to be identified more consistently. Yet, it continues to remain an area of concern because of the manner in which it affects nearly every aspect of its victim’s life.

Derek Oliver, Dixie State University Social and Behavioral Sciences The use of birth interventions has been steadily increasing over the past several decades based on largely non-medical factors. It is thought that the various birth interventions (i.e. forceps, vacuum extraction, epidural, etc.), pitocin use, the mother’s attachment and psychological constructs during pregnancy are related to the incidences of neurodevelopmental disorders. Thus, the current study attempts to understand the association between birth intervention and the development of neurodevelopmental disorders. Three hundred mothers of children between one and five years of age were recruited using social media, flyers and phone calls. Mothers provided access to their medical records of the birth of their child as well as incidences of neurodevelopmental disorders in their children. Mother’s hospital records were obtained to determine length of pregnancy, duration of labor and rate and duration of pitocin use. It is expected that there will be a significant correlation between developmental disorders and interventions broadly. Further, it is expected that pitocin use will be positively correlated with incidences of autism.

Rebecca Holland, Brigham Young University Social and Behavioral Sciences Dialectical Quichua throughout Ecuador faces disappearance through the development of Quichua Unificado, a standardized form of Quichua used the bilingual school system. This form of Quichua was created in hopes that introducing a standardized orthography would help bilingual schools effectively address the Quichua language loss that is pervasive throughout the country. However, as the language steps beyond its intended bounds of being a written language and moves toward replacing dialectical Quichua as a spoken language, it is evident that this revitalization movement is progressing at a great cost. Original ethnographic research in the Napo Valley of Ecuador asserts that this movement is ineffectual at reversing the Quichua language loss in this area, and may in fact prove fatal to the future of spoken dialectical Quichua.

Lyndsey Craig, Dixie State University Social and Behavioral Sciences The ability for caregivers to read infant cues accurately is important for the development of infant regulatory capacities and attachment formation. Caregivers with insecure attachment representations may misinterpret infant cues and respond inappropriately. Anxious-ambivalent and avoidant attachment representations were examined with accuracy of interpreting infant engagement and disengagement cues. In an online survey, 112 college students completed the Experiences in Close Relationships-Revised scale and interpreted images of infants’ engagement and disengagement cues. Anxious-ambivalent attachment was negatively correlated with accuracy of interpreting engagement cues. Caregivers with anxious-ambivalent attachment representations may respond inconsistently to their infants and promote the intergenerational transmission of insecure attachment. These results suggest a potential target for education efforts for new parents.

Brandon Hansen, Utah Valley University Social and Behavioral Sciences Measuring eye movements during reading is an effective and ecologically valid way to investigate dynamic changes in human cognition. The boundary technique (Rayner, 1975) is often employed during experimental reading research by changing text in real-time between eye movements—permitting subtle manipulations which are not obvious to the reader. Frequently, these manipulations include the replacement of a target word (beach) by words that are homophones (beech), semantically related (shore), orthographically related (bench), or by random letter masks (hxnzt). Understanding the differences between text in which the target word is available (beach) and denied (hxnzt) allows a deeper understanding of dynamic cognitive processes. In a real-world sense, such investigations yield findings that assists doctors, clinicians, and educators as they create interventions for those, for example, with learning disabilities such as dyslexia.

Brendan Willis, University of Utah Social and Behavioral Sciences Most people at some point in their lives will encounter a situation where they witness, perpetrate, or fail to stop an action that seriously violates their moral beliefs, events that have recently been termed moral injuries. Litz and colleagues (2009) proposed a theoretical framework that suggests such moral injuries may interact with various protective and risk factors in order to result in either positive or negative outcomes. Negative outcomes could include feelings of guilt, shame, self-condemnation, and alienation. Positive outcomes could include individuals realizing that they have done something wrong, but accepting that they are not bad or evil and resolving to become a better person. A vital part of this framework is the concept of meaning making, the process by which individuals grapple with understanding and constructing meaning regarding their participation in events that violate their moral beliefs. The degree to which an individual is able to adaptively make meaning of a potentially morally injurious event is believed to serve as a mediator in the association between experiencing such an event and developing negative consequences. Specifically, the more adaptively an individual can make meaning of a morally injurious event, the less negative will be the outcomes. However, this mediational role of meaning making in the association between moral injury and psychological distress is a proposition of the theory that to date has not been empirically tested. Given its importance in the moral injury model, the purpose of this study is to empirically test whether or not this association exists. Understanding meaning making’s role in the moral injury model will help form a foundation of empirical work on which future research can build.

Chad Clayton, Brigham Young University Social and Biological Sciences Great Britain declared war on Nazi Germany in September 1939, alongside France. Within a year, France would fall to the German Blitzkrieg and England would stand alone in Europe against the Third Reich. Winston Churchill, the British Prime Minister, in a radio broadcast on June 18, 1940, told the British people that, despite significant military losses in the Battle of France, “there are good and reasonable hopes of victory” upon which they must resolve to carry on. With France already conquered and The Soviet Union out of the picture, the British must have known how big of a risk they were taking. What motivated the British to face down such a foe? By examining the archival reports of the British Joint Intelligence Committee at the time, this study seeks to evaluate the British perception of German military strength in 1940 when the war began, and to see how their assessments of Germany’s military capability and plans factored into British military and political actions.

Chelsea Romney, Brigham Young University Social and Behavioral Sciences Getting adequate sleep is essential for optimal daytime functioning and has implications for both physical and mental health. There are several reasons to believe that social support may influence sleep outcomes. Although certain relationships (e.g., married versus unmarried) have been tied to sleep disturbances, little is known about the association between the quality of one’s overall social network and sleep. Thus, in the present study, we examined how the amount of supportive relationships in an individual’s social network is associated with sleep outcomes.

Jarrett Webster, Dixie State University Social and Biological Sciences This study sought to determine what type of influences a British accent has on Americans. It was predicted that American listeners would rate a British voice higher than an American voice across four traits: physical attraction, social attraction, credibility, and overall favorability. Participants were 197 undergraduate students from Dixie State University (68 men, 129 women). Participants were offered extra credit in return for participation and ranged in age from 17-60. Participants were randomly assigned to one of two groups. The experiment was designed as a between-subjects experiment. The control group heard an American voice and saw a picture of a man. The experiment group heard a British voice and saw a picture of the same man. Both groups were asked to answer questions that measured the four dependent variable traits. A multivariate analysis of variance was used to calculate results. The hypothesis was confirmed for all of the traits except credibility. These findings have ramifications in interpersonal relationships in business, educational, and social settings.

Chase Jenson, Utah Valley University Social and Behavioral Sciences In May of 1940 Britain demilitarized the island of Guernsey which created the opportunity for German occupation. Some of the citizens left the island, but those that remained became imprisoned for the next five years. While there is a significant amount of research that is done on the topic of extreme circumstances during World War 2, the archived data of the events and social interactions of the people of Guernsey remains unexplored despite being the only part of Britain under German rule. To address this, final stages of conducting an exploratory study are in progress to discover reasons for resistance and collaboration of the imprisoned island inhabitants by content analysis of secondary data including government records, interviews, and journals.

Tanner Mortimer, Utah Valley University Social and Behavioral Sciences Surveys show that nearly half of all Americans reject evolution as an explanation of the origin and diversity of life on Earth, especially when concerning human evolution. (Gallup 2007). Furthermore, there is a correlation between the rejections of evolutionary science with a belief in a Christian God-creator (Gallup 2007).

Natalie Blanton, University of Utah Social and Behavioral Sciences The rates of women interacting with the criminal justice system are increasing steadily—yet little is known about the experiences of these women with/within the system as well as the latent effects that follow them throughout their lives. With a sociological perspective, one comes to understand the immense impact of experiences, inequities, and health/wellness/opportunity disparities in individual’s lives—especially within the criminal justice system. This project takes a multi-pronged feminist perspective/approach to women’s interaction with such.

Michael Christensen, Brigham Young University Social and Behavioral Sciences Suicide is a major problem for students in Utah middle and high schools. Since adolescents spend a large portion of their time on social media like Facebook and Twitter, there is a wealth of information we can learn about their personalities, moods, and interests by exploring their online interactions with others and specifically the statuses and messages they post publicly. We have created a Facebook app to mine this data and report the mood of a logged-in user’s entire network based on the individual classification of community members’ posts. We contribute to the Public Health field by aggregating suicide-risk factors and facilitating intervention, the motivation being to help others better identify and help those who are at-risk for suicide based on their online behavior. We contribute to the Computer Science field by creating a machine learning algorithm that can classify text into one of several fine-grained mood categories, learning to identify more than just positive or negative sentiment. In addition, our algorithm has the ability to update online by receiving feedback from the users on how well or poorly it classified the text of their friends’ posts. We describe our algorithm and report on preliminary results about its performance on real-world data.

Zack Bjerregaard, Weber State University Social and Behavioral Sciences The research presented here will lay the groundwork for a larger project as part of iUTAH that will examine the interrelationships and feedbacks among hydroclimate and the ecological and human aspects of urban and montane landscapes in the Wasatch Range Metropolitan Area (WRMA). To assess how human systems and urban development patterns influence water sustainability, we developed a typology of neighborhoods in the WRMA based on sociodemographic and climate variables and built environment characteristics that previously have been found to affect water system dynamics. Using GIS and statistical analysis programs, variables were aggregated to census block groups (CBGs), which we determined were a satisfactory proxy for neighborhoods in most urban areas. Previous studies show that neighborhoods are an important level of measurement because of their influence on individuals’ behaviors. Only CBGs that had a recalculated population density of at least 50 people per square mile after subtracting areas of water and/or federally-owned land were included. A statistical factor/cluster analysis was performed on these variables, which returned a typology of neighborhoods and their spatial distribution based on water usage. The typology will be used by other members of the project to target a select number of each neighborhood type, where instrumentation and further data collection will be implemented to examine the impacts of urban development patterns on water sustainability and the wider ecological and physical hydroclimate.

Quinn Linford, Utah Valley University Social and Behavioral Sciences Background: Mt. Timpanogos has been an attraction for the residents of Utah Valley and has become a center of recreation for much of Utah. For many years Mt. Timpanogos was the home of an annual hike hosting a daily crowd of approximately 18,000 people. After being designated a wilderness area in 1984, the annual hike was banned. However, the mountain remains an attraction for many residents of the surrounding valleys and visitors from around the world. Currently one- to two-thousand people hike the mountain on mid-summer weekends. This concentration continues to push the limits of the mountain’s ability to accommodate while balancing the opportunities for solitude and unconfined recreation.

Brooke Bradford, Utah Valley University Social and Behavioral Sciences Research in the area of sexuality indicates that females tend to be more flexible in their sexual behaviors than males.(Baumeister, 2000) Studies also seem to indicate that there is a more permissive and accepting attitude towards women’s bisexual behaviors than towards men’s bisexual behaviors(Lippa, 2006; Savin-Williams, 2006) The present experiment was created in order to measure the perceptions of bisexual behavior held by Utah Valley University students. One hundred students were asked to read brief descriptions of similar sexual behaviors participated in by men and women. Participants were asked to rate these sexual behaviors on a scale and indicate if they perceive the behavior as heterosexual, questioning, bi-curious, bisexual or homosexual. The participants were then asked to rate behaviors on a scale of acceptability as well as a scale of commonality. The questions consist of similar behaviors being engaged in by males and females in order to test for changes in perceptions of the sexual activity occur based on the gender of the actor in the scenario. It is hypothesized that the results of these surveys will support current research in this area and confirm that the scenarios featuring females will be rated as more acceptable, common and placed in the bisexual categories.

Chauntelle Gates, Dixie State University Social and Behavioral Sciences Prenatal maternal stress (PNMS) can affect the brain development of the fetus and we know early experiences, even during gestation, shape the way our brain is developed. Since the brain growth of the fetus is rapid, any stressful situation can alter the rate at which the brain develops resulting in an under developed brain at the time of birth. This paper focuses on potential risks associated with prenatal maternal stress to the developing brain throughout gestation and preventive measures to reduce risk. Prenatal care is used throughout the world in a preventive manner to ensure optimum health and welfare of the mother and her baby, throughout gestation. Prenatal care is imperative and should take place during the first trimester to prevent potential risks to the fetus. It detects early signs of abnormalities in the infant, benefiting the mothers’ overall health. Mothers who take advantage of prenatal care, especially when PNMS occurs, have better birth outcomes and overall the brain development of the fetus is less effected. Other life situations could affect the brain development of the fetus but this paper will only focus on the effects PNMS has on the brain.

Jenna Deelstra, Weber State University Social and Behavioral Sciences The purpose of the present study was to explore the impact of facilitative mental imagery training on distance runners. Female (n=20) and male (n=11) athletes, separated by skill level classifications: Collegiate (n=19) and recreational (n=12) completed the Motivational Imagery Ability Measure for Sport (MIAMS) before and after 21 days of mental imagery training. Included in the training were relaxation and breathing techniques followed by guided imagery related to distance running training and competition. Physiological data including galvanic skin response (GSR), skin temperature, and breathing rate were also measured while participants took the MIAMS survey, which asked them to imagine and experience a competition. A One-way Analysis of variance (ANOVA) examining the effects of the imagery training on MIAMS survey responses between collegiate and recreational athletes for motivational general-mastery imagery (MG-M) and arousal imagery (MG-A) was employed. Significance was found in the emotional response evoked and the ease of producing imagery between the two groups. Post-training skin temperature and galvanic skin response (GSR) between the two groups was also significant. These findings support previous research indicating that imagery is both a talent and a skill that can lead to better emotional control in competitive athletes. More research must be done to better understand the effects of mental imagery training on male and female distance athletes.

Tyler Moore, Brigham Young University Social and Behavioral Sciences A fundamental concept in behavioral economics is that of loss-aversion, that is, the differentially greater effect of loss when compared to gain. The law of relative effect (also known as the matching law) provides the framework for precise behavioral measurement of that differential in a hedonic scale. We recently developed a video game by which to achieve that measurement. Participants will be invited to play the game during a series of sessions in which gain and loss contingencies are varied–sometimes the participant will gain points and sometimes lose them. In addition to varying the relative frequencies of gains and losses in order to measure their relative effects on behavioral choice, we will measure the effects of an additional variable by means of a different group of participants. This second group will win or lose points in one condition of the experiment and, in the other condition, win or lose actual money. It is our prediction that the group experiencing the loss of money rather than points will demonstrate behaviors indicative of a greater aversion to loss than their counterparts, who will merely lose points.

Kathi Beckett, Brigham Young University Social and Behavioral Sciences The Kallari Association, a group of self-governed organic cocoa producers located in the Napo Province of the Ecuadorian Amazon, is creating sustainable income through cacao farming and the production of organic chocolate bars in Ecuador. Using interviews and participant observation, I conducted fieldwork with six different Kichwa cacao farmers from five different communities in the Amazon area of Ecuador during the summer of 2013. In my research, I focused on the farmer’s reasons for involvement in the Kallari Association, the local community cooperative. These farmers expressed that they were driven by a desire for an increase in profits, agricultural knowledge, and education. At the same time, their involvement in the cooperative seems to have created a dilemma for them. On one hand their participation strengthened the teaching of Kichwa cultural traditions, and increased their access to food and educational opportunities, while on the other hand, the increased educational opportunities appears to have contributed to a loss of Kichwa cultural traditions.

Pratik Raghu, Westminster College Social and Behavioral Sciences Divided between India and Pakistan in multiple senses, Kashmir is home to the one of the world’s oldest yet least discussed civil conflicts. India and Pakistan continue to defend their claims to Kashmiri land, but most political thinkers agree that establishing an independent democratic state is the only way to ensure long term politico-economic stability in South Asia. However, what should this democracy look like?

Mary Barnewitz, University of Utah Social and Behavioral Sciences Analysis of archaeofaunal remains aids in the understanding of the ecological effects of past human prey-species exploitation. Sea otters (Enhydra lutris), in particular, were intermediate-return prey for late Holocene human populations along the California coastline. At the Yerba Buena Shellmound, on the San Francisco Peninsula, there is significant evidence of sea otter use by the local human inhabitants from 1950-1000 14C YBP. This study aims to investigate the use of sea otters at this site in order to address the implications of human subsistence patterns and the use of natural resources during this time period. The study will examine sea otter epiphyseal fusion and tooth crown height as measures of age, as well as comparative indices with other larger and smaller prey animals, in order to determine the age structure and abundance of this prey species over the time of site occupation. Given the breeding ecology of the sea otter, prey depression is often signaled by an increase in mean age over time. Prey resource depression is also signaled by decreases in the use of large-prey animals, and an increase in the lower return, small prey. Comparing the sea otter remains in the site to other taxa will provide more information regarding the significance of sea otters as prey. In general, a mean age increase in sea otters is indicated by the Yerba Buena sea otter tooth remains, but to a much lesser extent by the fused and unfused sea otter bone specimens. The interpretations of the comparative indices are still in progress. Nevertheless, the preliminary results support other evidence revealing over-exploitation of local resources in the San Francisco Bay area. Understanding the effect of past human behavior and subsistence patterns on local ecology is an important pursuit as it can help guide our management of future ecological resources.

Andrew Broadbent, Utah Valley University Social and Behavioral Sciences Introduction: Timpanogos is the second highest peak in Utah County, and has the highest visitation in the state, despite having no stand-out features such as being the highest or most technical. Over the years Mt. Timpanogos has been valuable go-to wilderness area for recreating Utahns. It also has developed a unique sense of place in the way that famous locations like Yosemite and Yellowstone have. Now Timpanogos has exceptionally high visitation and trail use relative to other recreation areas in the US. One purpose of this research is to explain what makes this peak special to visitors and what can be done to improve the visitor experience in areas such as littering, trail cutting, and overcrowding.

Andrew Fletcher, Utah Valley University Physical Sciences Springville, Utah, is known for its high water table and many freshwater wetlands and springs, which gave rise to the name of the city. Flooding of barns is a common problem among farmers in western Springville, which is just east of Utah Lake. These frequent barn floods are anecdotally linked to high-intensity precipitation events and the common use of flood irrigation. The objective of this study is to determine the cause of barn flooding and to make recommendations for mitigation of barn flooding for individual farmers with whom we are working in this area. The objective is being addressed first by using ArcGIS to determine the watershed of each barn and the NRCS (Natural Resource Conservation Service) Web Soil Survey to map hydrologic soil groups within each watershed. Results from the larger-scale Web Soil Survey will be supplemented with measurements of soil hydraulic conductivity using the SoilMoisture Equipment Model 2800K1 Guelph Permeameter. The above data will be used in the NRCS Curve Number Method to estimate the volume of surface runoff expected in a 100-year 24-hour precipitation event. The objective is also being addressed by installing shallow, hand-augured wells for monitoring the depth to the water table during high-intensity precipitation events and flood irrigation events. The results will be used to develop recommendations for a combination of (1) installation of French drains for diversion of stormwater (2) modification of current irrigation methods (3) pumping and diversion of groundwater. Results and specific recommendations for individual farmers will be presented at the meeting.

Nils Otterstrom, Brigham Young University Physical Sciences Filtered photodiodes show potential as inexpensive laser wavelength meter. Photocurrents are measured digitally. The photocurrent is digitized using externally controlled integration times to achieve the highest precision possible from the digital to analog converters on the photosensor chip. Using an algorithm we’ve developed and calibrated intensity curves, we can precisely calculate wavelength from the output of the different photodiodes. Limitations due to etaloning from reflections off of the surfaces of the filters were analyzed and effectively mitigated, allowing the device to achieve high precision with a stability of 0.102 nm over several hours.

Brittney Thaxton, University of Utah Physical Sciences There are many undocumented shorelines seen in Utah. As many as 30+ shorelines have been identified along the edges of the basin throughout the state. The purpose of this study is to characterize undocumented shorelines and identify potential evidence for tsunamis that might have occurred in Lake Bonneville thousands of years ago in areas such as Little Mountain, Stansbury Island, and Promontory Point, Utah. Lake Bonneville existed 32-10K years ago and was influenced by the Wasatch fault which was active as early as the Miocene. Scarps of this age are common and range between 15-20 feet in height (Machette, Personius, Nelson, Schwartz, Lund 1991; Dinter, Pechman, 2004a and 2004b). Several faults beneath Lake Bonneville could have produced tsunamis. The more water that is displaced the greater the tsunami will become and leave a greater impact onshore (Dutykh and Dias 2009). The East Great Salt Lake fault cuts NS across Bear River Bay east of Promontory Range. This fault line is an excellent candidate for causing a tsunami during the Lake Bonneville highstand because it is beneath the Great Salt Lake meaning it would have uplifted the entire water column of Lake Bonneville and since it is also close to the Promontory Range, it is likely it would leave tsunamite evidence along the shore. The fault rupture interval is between 3,000 and 3,500 years meaning fault ruptures could produce a tsunami during the lake’s high stand. Tsunamite is the term used for deposits related to tsunamis. The tsunamite features found along the shorelines will be similar to sedimentary features such as normally graded sand, mudstone clasts, and other gravel deposits that are out of place with the known shorelines (Shanmugam 2006). This is a unique opportunity to discover ancient tsunami evidence in Utah, a topic that has yet to be pursued.

Nicholas Labrum, Utah State University Physical Sciences Increasing concerns on the anthropogenic climate change, rising global energy demands, and diminishing fossil fuels have urged the search of alternative carbon-neutral and sustainable energy resources, among which solar energy stands out as the most promising target since it is the largest exploitable resource. However, its nature of diurnal variation, intermittence, and unequal distribution requires efficient and cost-effective capture, conversion, and storage. Generation of chemical fuels, such as hydrogen, from solar energy input represents an appealing approach to meet this goal. An ideal scheme would tap hydrogen from the splitting of water with concomitant evolution of oxygen. Due to the nature of the four-proton and four-electron process, water oxidation is the bottle neck of the overall water splitting process. Nature catalyzes water oxidation using an oxygen evolving complex (OEC) in photosystem II. This project aims at mimicking the OEC to prepare and investigate bimetallic Mn-Ca catalysts for water oxidation catalysis. Calcium has been reported to be critical in water oxidation by OEC, however its functional role has not been well studied. By positioning a calcium atom in the second coordination sphere of manganese in molecular scaffolds, we are able to systematically study the functional role of calcium at the molecular level. Our project will prompt the development of water oxidation catalysis and benefit artificial photosynthesis at large.

Greg Carling, Brigham Young University Physical Sciences Wyoming the second most glaciated state in the lower 48 United States has seen drastic changes in the size of its glaciers. Glaciers in high elevation ecosystems of Grand Teton National Park are not anywhere near to the size that they were 100 years ago. The glaciers continue to decrease in size every day. As the environment changes the glaciers change in size and can be affected by many factors in the environment. Deposition of particulate matter from the atmosphere into the glaciers occurs as pollution is becoming worse and more common. Studies done throughout the world have shown that glaciers can act as a source for mercury and other trace metal elements in high elevation ecosystems. Through the assistance of the UW-NPS Research Station Dr. Greg Carling of BYU and his team of graduate and undergraduate assistants retrieved 100 glacial melt water samples from the Middle Teton, and Teepee Glaciers and stream sites in Garnet Canyon, and from the Teton Glacier in the Glacier Gulch area. In the data analysis completed up until this point, concentrations of various trace elements have found in sample sites in close proximity to the Middle and Teton glaciers on the glacial moraine. We hypothesize that these glaciers act as a source for mercury and trace elements that can then be transported to lower elevation ecosystems within the Greater Yellowstone Ecosystem.

Tucker Chapman, Brigham Young University Physical Sciences The Provo River provides the opportunity to study three systems from low to high anthropogenic activity. Its headwaters are in an undeveloped area of the Uinta Mountains. The river then moves into a valley that is developing from an agricultural to an urban system. The lower portion of the river moves into the urbanized Utah Valley. These systems give the ability to study the changes in trace element chemistry from a variety of sources. Trace element data were collected during the 2013 water year including the spring snow melt. Correlation was analyzed among the different trace elements using multivariate statistics in order to discover trace element sources. The element loads were calculated using USGS Load Estimator (LOADEST) software. The study has implications involving the drinking water of >2 million people in the Utah and Salt Lake valleys and the changes that the shift from agriculture to urban is causing.

Isaac Allred, Utah State University Physical Sciences We examine the number and location of Class II wells in the central U.S. to constrain future work on the potential for induced seismicity. The EPA, state oil & gas commissions, scientific papers, and media stories frequently state that there are ~140-160 k Class II wells. Excluding California, we expected to find approximately 120 k wells; but instead found ~ 82 k active injectors in the available databases. State datasets vary in accessibility, availability, and content of well data. Lack of digitized well data also limited our online search, and several states require FOIA requests to be filed. State databases with poor searching and sorting functions further complicated data mining, requiring a well-by-well search, and for several states, well locations and injections were difficult to determine. Common discrepancies between EPA well totals and state database totals appear to be due to counting of plugged and abandoned wells, and wells that are permitted but not in use. No data has been retrieved for about 1,600 wells on tribal lands and Indian Country, and several states would not provide “confidential” well data. Of the active injectors, at least 55 k wells inject into producing, pressure-depleting oil and gas formations and are less likely to generate damaging earthquakes. Of the ~ 16 k non-EOR wells, we found 3,400 wells that inject at depths > 1.8 km, where most M > 3.0 midcontinent earthquakes occur. We will present examples of data from several states, that show the locations and depths of injectors, earthquakes, depth to basement, and we will provide an overview of the public file sharing system of the data. We will search for correlations between the depth of injection, the number of injection wells, recent seismic activity, the nature of the subsurface geology, and regional stresses.

Adam Blair, University of Utah Physical Sciences Objectives: Histone covalent modifications influence regulation of gene expression. Changes in histone covalent modifications are triggered by abrupt changes in environment, such as preterm birth followed by mechanical ventilation (MV). Whether histone modifications also occur in the kidney of chronically ventilated preterm lambs is not known. We hypothesized that ventilation of preterm lambs affects histone modification in kidneys.

Christopher Clements, Utah Valley University Physical Sciences DWR operates the Springville Fish Hatchery raises rainbow trout for stocking lakes and ponds. Since February 2011 the hatchery has observed excessive physical activity among the trout, including jumping out of raceways onto the concrete walkways. Excessive physical activity can result from free carbon dioxide levels above 10 ppm and free carbon dioxide levels in the hatchery water have been measured as high as 17 ppm. They have added some treatment processes before it enters the hatchery and greatly reduced the food intake of the trout, which increase costs and reduce production. This has reduced free carbon dioxide levels to only 15 ppm. The objective of this study is to determine the source of elevated free carbon dioxide and recommend solutions for the problem. The water source for the hatchery is a shallow pond, which is fed by 16 springs, both warm and cold. The objective is being addressed by measuring discharge from each spring and collecting water samples for measurement of free carbon dioxide in addition to other common stressors of rainbow trout. Free carbon dioxide, temperature, pH, electrical conductivity and dissolved oxygen are being measured on-site, while hardness, nitrite, ammonia, copper, iron and zinc are being measured. Free carbon dioxide levels at some warm springs have been measured as high as 25 ppm. Mixing calculations will be carried out to determine whether the discharge and water quality of each spring is consistent with the water quality currently entering the hatchery and whether the removal of one or more springs would result in sufficient water within the acceptable ranges for rainbow trout. If calculations estimate free carbon dioxide significantly lower than the measured free carbon dioxide in the water entering the hatchery, it is possible that additional elevated free carbon dioxide results from the decay of organic matter.

Joshua Wallace, University of Utah Physical Sciences We study the effect of the circum-galactic gas environment on the observed Lyman-alpha emission from Lyman-alpha emitting galaxies. These galaxies are primarily high-redshift star-forming galaxies that are important in understanding both galaxy and universe evolution. The Lyman-alpha photons emitted from these galaxies should hold valuable clues about the general environmental properties (such as gas velocity, density, and distribution) around galaxies, since the photons can be strongly affected and scattered by the neutral hydrogen atoms that make up the majority of the gas. However, explaining exactly how a galaxy’s environment affects its Lyman-alpha emission is very complex and currently cannot be predicted with complete certainty — every time a Lyman-alpha photon interacts with a hydrogen atom, its direction and frequency are changed, which in turn affects how far it will travel before the next interaction. We study the environmental effects on Lyman-alpha emission properties by applying Monte Carlo Lyman-alpha radiative transfer modeling to simple analytic models and find an important role of the anisotropic distribution of gas in determining the observed photometric and spectral properties of Lyman-alpha emission. We further perform a detailed investigation by applying the radiative transfer modeling to realistic star-forming galaxies in high-resolution cosmological galaxy formation simulation. From our analysis so far, we find the Lyman-alpha emission from the models shows a strong dependence on viewing angle, as well as correlations between observed spectral features and environmental conditions. We plan to model and analyze a large sample of simulated galaxies to better describe and statistically quantify the above dependence and correlations. Our study will lead to a better understanding of the effects galaxy environment on the observed Lyman-alpha emission and in turn provide a theoretical guide on how to use observed Lyman-alpha emission to learn about the environments of star-forming galaxies and hence galaxy formation and evolution.

Ben White, University of Utah Physical Sciences We evaluated the ambient noise wavefield of select arches in the Moab area as a means to assess changes in their structural health over time. Our measurements revealed that the fundamental frequency of vibration at Mesa Arch and Corona Arch are both in the range of 3 Hz, while other spectral peaks are likely related to higher-order vibrational modes. We use numerical modeling for modal analysis in an attempt to predict and visualize the various modes of vibration and their frequency Resonant frequencies are projected to change with snow or rain loading or after a strong earthquake. By monitoring resonant frequencies over time and under various environmental conditions, our goal is to detect reversible and/or irreversible changes that may accompany damage of these arches.

Enoch Lambert, Brigham Young University Physical Sciences Extended-cavity diode lasers are important tools in scientific research. Current extended-cavity diode laser systems will change frequency unpredictably while operating, requiring extensive effort to tune them back to the right frequency. We seek to implement a novel method of extended-cavity diode laser control that adds an extra control system to prevent these unpredictable changes.

Jeff Selck, Utah Valley University Physical Sciences Stream discharge through narrow, deep slot canyons can be a major source of groundwater recharge in the arid Southwest. Various state and federal agencies use the empirical Manning Equation to predict the discharge through artificial slots created for diversion of rivers around coal mines. However, it is not obvious that the Manning Equation could be applied to slot canyons or artificial slots as the data base used for development of the Manning Equation did not include either natural streams or artificial structures for which most of the friction occurs along the sides of the channel. The objective of this research is to develop an empirical formula for estimating the Manning roughness coefficient for flow through narrow, deep slots. The objective is being addressed by measuring stream discharge through natural slot canyons in southern Utah that are fed by perennial streams, springs or dam outlets. Based on measurements at ten sites along eight streams, the best estimate for the Manning roughness coefficient is n = 0.873nJ exp(5.108A/w2) where A is stream cross-sectional area, w is stream width, and nJ = 0.39S0.38R-0.16 is the roughness coefficient estimated by Jarrett (1984) for high-gradient streams, in which S is slope of the stream bed and R is hydraulic radius (ft). The new formula estimates stream discharge with a mean accuracy of 44%. On the other hand, Jarrett’s (1984) formula underestimates stream discharge by 1-2 orders of magnitude for aspect ratios A/w2 in the range 0.6-0.7. The new formula will be refined by additional measurements on slot canyons, artificial diversions, and a laboratory hydraulics bench. It is hoped that the new formula will lead to a more realistic design for artificial slot diversions.

Jared Weaver, Southern Utah University Physical Sciences Organoarsenic are compounds containing carbon and arsenic. These compounds have been shown to have biological activity and pharmaceutical properties, and some organoarsenic compounds have even displayed potential for aiding in current medical problems up to and including possibilities as anticancer agents. Currently relatively little research is being done on organoarsenic compounds by the pharmaceutical community due to current views from the media based largely upon the toxicity of their inorganic arsenic counterparts (inorganic compounds are compounds not containing carbon), organoarsenic compounds however have significantly toxicity. Also, like with any medicine, toxicity depends predominately upon concentration, and given a high enough concentration organoarsenic compounds would logically follow the same trend. Synthesis of a large variety of novel organoarsenic compounds has been found via a reaction involving a variety of aldehydes or ketones and 2-(Dichloroarsino)benzaminium chloride. Research will focus on synthesis, isolation, and characterization of a library of organoarsenic compounds and then determine their respective biological activities. Synthesis will determine mechanistic requirements of said reaction and will be done to produce a diverse selection of organoarsenic compounds. Compounds will be isolated through precipitation of product and vacuum filtration of formed product. Structure will be determined through IR, NMR, and Gas Chromatography/ Mass Spectrometry, and through X-ray crystallography. Biological activity is suspected with potential for testing via a Kirby-Bauer Disc treatment. It is hypothesized that novel organoarsenic products will be formed by reaction of 2-(Dichloroarsino)benzaminium chloride with all carbonyl compounds containing an alpha carbon with at least one proton used, and that compounds synthesized will inhibit bacterial growth.

Kelly Hoerger, University of Utah Physical Science Implant devices such as orthopedic, dental, and cochlear implants are commonly utilized as part of many medical treatments. However, these foreign objects are susceptible to bacterial contamination, thereby putting the host at risk of an infection that is challenging to eliminate due to biofilm formation. Biofilms are formed when a bacterial cell adheres to and colonizes such metal or plastic surfaces. The cells aggregate to form and embed themselves in a thick and protective polysaccharide matrix, making biofilms resistant to many antibiotic treatments.

Adam Kingsley, Brigham Young University Physical Sciences In the construction of various sensors in the lab, highly accurate integration times are required. It is advantageous to have a precise external timer to run the circuitry contained in the sensor. By taking a signal in the range of megahertz down to hertz or milihertz range, it is possible to control the start and stop times for circuits. Overall this means that every time a measurement is taken it represents the same length of time.
