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.

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.

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.

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.

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.

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.

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.

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.

Jay Winters, Brigham Young University Social and Behavioral Science The common stereotype of feminism has a negative connotation implying that feminist’s are simply radical women’s rights activists. The reality is that feminism is hard to define given its complexity and the range of issues it encompasses. A scale was developed in 1994 called the Attitudes Toward Feminism and the Women’s Movement (FWM), which sought to predict attitudes toward feminism (Fassinger, 1994). Many social psychologists see it as an effective way of predicting attitudes despite its age or lack of an emotional component. Our Assessment of Feminist Attitudes (AFA) scale was developed to include an emotional response component as well as provide a contemporary view of the ever-changing feminist movement. Our study is in the process of being assessed for statistically significant data. The effectiveness of the AFA in measuring feminist attitudes will be known in the coming weeks.

Madeleine Ary, Brigham Young University Social and Behavioral Sciences In 2010 I conducted research in the city of Cambridge England on the relationship between the Muslims of Cambridge and the police of the same city. I conducted this research primarily through single interviews and data analysis from the United Kingdom in general and England specifically. From this research I discovered that the relationship between these two groups was maintained by frequent, mutual contact and trust. England at the time was experiencing a summer of rioting, much of which revolved around Islam. This may have increased the difficulty in such a faith group, authority relationship, however their efforts to maintain a positive relationship only intensified and there was little to no real disruption within the Cambridge Muslim community. My research demonstrates how such relationships can be effectively conducted even in otherwise tumultuous circumstances.

Clinton Hardy, University of Utah Social and Behavioral Sciences Coercive treatment practices, while controversial, are commonly employed (by mental health professionals and parents) when admitting adolescents into outdoor behavioral healthcare (OBH; e.g., outdoor/wilderness therapy) and residential-based treatment settings. While coercive practices have been investigated in various adult treatment contexts, to my knowledge no study has examined coercive practices or pressures among adolescent treatments. As the first of its kind, my report investigates the relationship between adolescent-perceived coercive treatment pressures (i.e., negative pressures) and their affective reactions reported when entering OBH treatment. Negative pressures, or the perceptions of “threat” and “force” during admissions, are measured via the Negative Pressures Subscale (NPS) of the MacArthur Admission Experience Survey (AES). Affective reactions to entering treatment are measured via the Positive and Negative Affect Schedule – Expanded Form (PANAS-X). Although this study is still taking place, my interim analysis (N = 36, age range: 14-17) has so far demonstrated the following predicted relationships between negative pressures and affective reactions in OBH treatment admissions: An adolescent’s increased perception of negative pressures significantly correlates with (a) increased affective distress (r = .377, p = .037), (b) decreased affective positivity (r = -.61, p < .001), and (c) increased affective hostility (r = .464, p = .003). Therefore, significant medium to large correlational effect sizes are reasoned to be imminent. In recognizing that negative pressures might not only relate to an aversive admissions experience, but also negatively impact or delay positive treatment outcomes, future research is concluded to be essential.

Daniel Cardoza, Brigham Young University Social and Behavioral Sciences This paper aims to offer an introductory platform to the correlation between Russian fatalistic tendencies and conversion to Protestantism. It argues that fatalism is a central aspect of the Russian collective conscious, something that is fundamentally at odds with the Protestant temperament as outlined by Max Weber in his book, The Protestant Ethic and The Spirit of Capitalism. What happens when a Russian converts to a Protestant religion? This paper specifically focuses on conversion to one religion, The Church of Jesus Christ of Latter-day Saints (LDS). Analysis of data gathered through ethnographic interviewing and participant observation shows that a correlation might exist between belief in LDS doctrines and a reduction of fatalistic tendencies. This paper serves an introductory basis for future research on this topic. As such, the paper also presents recommendations for further research.

Ryan Hill, Brigham Young University Social and Behavioral Sciences We analyze the presence of two types of framing bias in ballot wordings that affect election outcomes: status quo bias and agent-external loss aversion. Both of these biases are studied extensively in behavioral economics and likely have salient impacts on initiative or proposition measures in state elections. Status quo bias is the tendency of a voter to be more likely to maintain a currently enacted policy rather than passing a new law. Agent-external loss aversion is the tendency for a voter to be more likely to grant a right to a minority population rather than vote to restrict a right. Both of these biases have had important impacts on the outcome of recent ballot initiatives especially on California Proposition 8 that failed to legalize the right of marriage for same-sex couples. We test the salience of these framing biases by conducting a nationwide survey experiment that randomly assigns different ballot wordings for the same policies across different survey respondents. The survey mimics a real voting situation and the randomization of questions ensures that we can identify the specific effect of each bias on the voting outcome. We analyze the treatment effects using difference of means and ordinary least squares analysis. We also extend our analysis to examine whether moderating variables such as political knowledge or opinion have an impact on the magnitude or direction of the bias effects.

Peter Busche, Brigham Young University Social and Behavioral Sciences An undergraduate study on young people in the Channel Islands (near England and France. Such questions will be addressed, such as: What makes growing up in a tiny Island community unique? How does leaving the Island for the outside world affect the young peoples’ transition into adulthood? This project consists of a descriptive outline based on 2 months of ethnographic research, as part of a 10,000 word senior thesis. Current anthropological and psychological theories are part of the overall construction of the data.

Ashley Jolin, University of Utah Social and Behavioral Sciences This paper analyzes the essentiality of creating a just European Union banking union between member states of the eurozone, in response to the European debt crisis. In 1992, the Maastricht Treaty established strict financial criteria for member states to follow, ensuring a strong economic environment to support the new currency union. However, numerous member states did not abide by these limits, and countries with weaker economic stability such as Greece and Ireland began to accumulate huge public deficits. As a response to this debt crisis, in June 2012 the key institutions and leaders of the EU proposed working towards a genuine Economic and Monetary Union, a banking union serving as the keystone of this project. I argue it is imperative that this banking union is designed to be successful at dissolving the current economic crisis and anticipating future problems, as the existence of the eurozone is contingent upon it.

Heather White, Brigham Young University Social and Behavioral Sciences The purpose of this poster is to illustrate the use of storyboards in visually evaluating exhibits and the visitor experience in a narrative museum. Storyboards, a key tool used to develop a visual story, can be used in museums to provide unique insights into the dynamic experience of visitors as they move through exhibits. This poster focuses on how storyboards can be used post-installation to evaluate how visual elements and space effect the visitor’s engagement and experience within exhibits. This poster will present storyboards for three exhibits and the resulting analysis. I analyzed the storyboards by examining artistic elements (line, color, shape, space, etc.) and design principles (unity, balance, scale, proportion, etc.) as they are formed and reformed throughout the storyboard. These changes are only noticeable because of the temporal aspect of sequenced storyboard images. The results show how the visual and spatial visitor experience encourages or discourages engagement with the exhibits. These results can be used, in addition to written and oral evaluation methods, to critique and improve exhibitions to be more accessible and engaging for future visitors.

Mason Bennett, Brigham Young University Social and Behavioral Sciences In the natural environment, rhesus macaques (Macaca mulatta) acquire social dominance rank through matrilineal family (mothers’) inheritance. It is unknown as to how high ranking matrilines initially become high in social dominance. Serotonin (5HT) has been linked to social dominance rank. Central Nervous System 5HT is modulated by both the serotonin transporter (5HTT) and MAO and both have been linked to social dominance rank. MAOa and the 5HTT are the two main variables controlling central serotonin. To assess the effects of genetic and temperamental variables on matrilineal rank and potentially the effects of rank on behavior and temperament, we examined: the serotonin transporter genotype and MAOa genotypes. Because low or unstable social dominance rank is stressful, leading to chronic hypercortisolemia we also measured stress-induced cortisol levels. Lastly we examined infant temperament ratings taken from a Bio-Behavioral Assessment (BBA) pioneered by John Capitanio. This test is performed over a 24 hour period when infants are 6 months of age, and includes a bio-behavioral battery of tests designed to measure temperament. Dominance was measured by wins/losses during head-to-head competition between all possible pairs in a group. Subjects included 2300 rhesus macaques raised at the California National Primate Research Center between the years of 2001-2012. Results showed that matrilines high in social dominance exhibited a significantly high rate of both the long allele of the serotonin transporter genotype, and for males a high frequency of MAOa allele 6. As infants, subjects from matrilines low in social dominance rank exhibited high cortisol, hypervigilance, low activity ratings, and high emotionality. This study is the first of its kind to suggest that the acquisition of dominance by a matriline is modulated by genetic influences and that it is likely that the serotonin system plays a role in this process.

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

Jason Lefrandt, Brigham Young University Social and Behavioral Sciences Dominant behaviors frequently occur in both human and non-human primates. In the non-human primate world, high and low dominance rankings are rated through interactions recorded within the group, specifically, aggressive and submissive behaviors. Dominance within Rhesus macaques (Macaca mulatta) also tends to be governed by a matrilineal effect: meaning that if two monkeys are in the same family, than both monkeys will show similar rankings within the group. This current study looks into how genotypic variables correlate with overall behavioral expression in dominance. Utilizing archived dominance and genetic data from the National Institute of Health including serotonin, MAO-A, and rearing, we analyzed the correlations with social dominance rankings of rhesus macaques. In order to control for matrilineal effects within established groups, all subjects were placed in smaller, newly formed social groups. This was done in order to facilitate great analyses of genetic influences on dominant behavior. Our original hypothesis was that macaques with long homozygote serotonin for the long allele; were mother-reared; and have the MAO-A gene will have high social dominant rankings. On the contrary, our preliminary findings have shown that subjects who were reared by mothers who were not genetically their own tend to show more dominant related behaviors, and are subsequently rated much higher than those subjects who were mother-reared or peer-reared.

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.

Jolysa Sedgwick, Brigham Young University Social and Behavioral Sciences Traditionally the Hmong in Thailand have made their living through subsistence farming and poppy cultivation. This arrangement had placed familial ties and religious influences at the center of Hmong cultural identity. Today, however, increased globalization has also meant a shift in cultural identity and priorities for the rising Hmong generation. This change is clearly seen in Nan Province where the decision to migrate or relocate to urban centers (such as Chiang Mai) for work is frequent. In the past, cultural identity and life decisions were heavily tied to kinship and religious influences. However, with the onset of globalization, the Thai State and current popular culture are becoming increasingly important to Hmong cultural identity and are becoming increasingly higher priorities in the lives of the Hmong who leave their childhood villages to pursue economic advancement and other activities in urban centers. In order to investigate this cultural shift, I conducted an ethnographic field study among Hmong living in three rural villages in Nan Province and among Hmong individuals in Chiang Mai. Using ethnographic field methods, I collected and analyzed the stories of those who decided or are in the process of deciding to relocate to Chiang Mai. In this paper, I present findings that support a shift in cultural priorities for those participating in urban migration and how that shift is influenced by increased global technology and connectivity. I explain that this shift is integral to understanding what the future will hold for the minority Hmong population in Thailand.

Kent Hinkson, Utah Valley University Social and Behavioral Sciences Post-traumatic stress disorder (PTSD) and depression both have individually strong relationships with academic performance and achievement. However, when considered together, the combination is associated with worse measures than either condition alone. Recently it has been suggested that student veterans may have elevated rates of PTSD and depression, which makes these conditions points of particular interest when looking factors that affect achievement and performance in school.

Lindsey Fields, Brigham Young University Social and Behavioral Sciences For my senior thesis in anthropology, I conducted fieldwork in a small Hmong village in northern Thailand studying the process of religion conversion. Traditionally, Hmong people practice a mixture of spirit rituals and ancestral worship known as Dab Qhuas and classified as shamanism. Within the past fifty or so years, other religious groups have emerged in the village both Christian sects and Hmong messianic groups. Though many in the discipline of anthropology argue that conversion is a break from traditions of the past, I observe that Hmong of this village in Thailand undergo a much more syncretic type of conversion. Though they identify as either Christian or of a Messianic sect, much of their practices and ideology retain elements of their shamanist past. Though they stress their differences in doctrine and practice, much of the ontology permeating shamanism and Hmong culture is still very much present. In order to better examine this phenomenon, I will focus the beliefs and practices in both Is Nbis and Christianity that take on slightly different forms in each religious practice, yet, still maintain some of the same ideologies. Rituals merely shift in order to fulfill the same metaphysical needs. By studying new practices that retain much of the feel of old culture rituals, I hope to illustrate that these Hmong are not as far removed from their traditional roots as they imagine themselves to be.

Michelle Hammon, Dixie State University Social and Behavioral Sciences A caregiver’s ability to meet their infant’s physical and emotional needs is important to development. Infants who are unable to get their needs met are at risk of developing an insecure attachment with their caregiver. The ability of the caregiver to empathize with and appropriately respond to the needs of their infant is dependent on the caregiver’s attachment representation. An online survey collected data from 112 college students. Participants completed the Experiences in Close Relationships-Revised (ECR-R) scale and the Interpersonal Reactivity Index (IRI). Insecure attachment representations were associated with the ability to empathize. Anxious-ambivalent attachment was positively associated with concern and distress and avoidant attachment were negatively associated with distress. These results suggest that attachment representations are important for the development of empathy.

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.

Patrick O’Connell, Brigham Young University Social and Behavioral Sciences Studies show that the CRH gene has several variants that are associated with psychopathological disorders and dysregulation of the HPA system, including a single nucleotide polymorphism (SNP) located on the promotor region (201 C/T). In rhesus macaques there is a orthologous SNP in the promoter region of the corticotrophin releasing hormone gene, CRH-248 C/T, that up-regulates the production of corticotrophin releasing hormone (CRH), inhibits the down-regulation of CRH expression in the presence of glucocorticoids, and is related to stress-induced alcohol consumption (Barr 2009). HPA Axis differences due to genotype will manifest initially in CRH concentrations, affecting the hypothalamic pituitary adrenal stress response (HPA axis). This effect translates peripherally in the form of plasma ACTH concentrations and subsequently in concentrations of plasma cortisol. 180 rhesus monkey subjects reared either with their mothers or in adult-absent, peer-only groups were genotyped and underwent a series of social separations from their attachment source. Blood samples were obtained one and two hours following separation to assay for ACTH and cortisol. Our analyses showed a significant effect of the orthologous CRH-248 genotype on plasma ACTH concentrations following repeated experimentally induced stress. Further analyses showed that this genotypic difference was only found however in the peer-reared subjects. Interestingly, analyses showed no effect of genotype on plasma cortisol levels. This finding suggests while negative feedback at the level of CRH is disrupted leading to pituitary hypersecretion of ACTH, intact negative feedback at the level of the adrenal cortex may moderate this dysfunction. Additionally, genotypic effects were only different after prolonged, chronic stress, as measured separations three and four. We suggest a GxE effect with CRH genotype effects only present after deleterious rearing experiences and chronic or repeated stressful situations.

William Ng, Utah Valley University Social and Behavioral Sciences This paper draws on leadership and behavioral theory in a public context to ascertain the full necessity of the sustainability officer to engender, sustain, and develop sustainability movements in higher education institutions and municipalities. As sustainability rises in awareness and demand from university and municipal stakeholders — influenced by political and educational discourse, the sustainability officer plays a vital role in conceptualizing, interpreting, and manifesting the abstract principles that stems from sustainability movements. Specifically, this study looks at the emergence of the sustainability officer, who they are, where they come from, what they do, and the outlook of future trends. Moreover, this paper looks at the structural positions of where sustainability officers fit in the organizational hierarchy and question whether they fall in line with contemporary political theory of public organizations. Furthermore, through interviews with Sustainability Managers/Coordinators/Directors, an intimate look into where they have been effective, where they could progress, and what they envision for themselves in the future has been garnished. Finally, these interviews manifest the establishment of the pragmatic connection between organizational theory and practice, allowing an exposition of the evolution of centralized sustainability leadership.

Lucas Brook, Brigham Young University Social and Behavioral Sciences Present day Peru finds itself in the midst of an interesting transition. Government decentralization is creating increased levels of political participation among the historically skeptical citizenry (Crabtree 2011). While some Peruvians participate through established institutional channels such as voting, campaigning or contacting political leaders, many others choose to engage in community improvement activities, private organization undertakings, or public protests as their avenue of political participation (Booth and Seligson 2009). What causes some Peruvians to participate in these extra-governmental activities while others use established government institutions? Although the causes of political participation are vast, this study focuses on political knowledge (both actual and perceived) as the independent variable. I hypothesize that Peruvians with less political knowledge (actual or perceived) understand (or at least perceive that they understand) less about Peru’s democratic institutions. Therefore, they will forgo participation through these established government institutions and employ extra-governmental means when participating politically. This hypothesis will be tested through the performing of regression analysis using data from Vanderbilt University’s AmericasBarometer survey project conducted in Peru in 2012. The results of this research will illustrate the effects that citizen’s political knowledge have on their participation in extra-governmental activism.

Lucas Lloyd, Utah Valley University Physical Sciences The high cost of air quality monitoring stations makes it difficult for citizens or local governments to monitor air quality in their own neighborhoods. For example, Utah County, Utah, with an area of 2141 mi2, has only four air-quality monitoring stations: (1) north Provo close to both Provo High School and Brigham Young University (2) Spanish Fork Airport (3) near State Street in Lindon (4) just south of SR-92 on 6000 W in Highland. The air-quality stations monitor levels of CO, NO2, O3, PM-2.5 (particulate matter smaller than 2.5 microns), and PM-10. The objective of this study is to find a much cheaper method of measuring air quality. The objective was addressed by measuring the magnetic susceptibilities of 10 replicates each of the leaves of 12 species of trees (cypress, crab apple, elm, flowering pear, green ash, honey locust, linden, Norway maple, pine, red maple, Russian olive, spruce) collected within a two-mile radius of each of the four air-quality monitoring stations in Utah County. After air-drying and crushing the samples, both low-frequency (0.46 kHz) and high-frequency (4.6 kHz) magnetic susceptibilities were measured with the Bartington MS3 Magnetic Susceptibility Meter. The best correlations between tree leaf magnetic susceptibilities and air-quality parameters were between the three-year average of PM-2.5 and the high-frequency magnetic susceptibility of leaves of pine (Pinus aristata) (R2 = 0.87) and Norway maple (Acer platanoides) (R2 = 0.86). The correlation was used with measured high-frequency magnetic susceptibilities of pine to estimate PM-2.5 in two unmonitored locations heavily impacted by highway traffic (corner of 800 N and I-15 and corner of University Parkway and I-15, both in Orem, Utah) on one day in August 2013. It was found that estimated levels of PM-2.5 were 9.5 µg/cm3 and 8.9 µg/cm3, respectively, which were within the EPA PM-2.5 Standard of 12.0 µg/cm3.

Frederickk Sudbury, University of Utah Physical Sciences Triphenylphosphine stabilized gold nanoparticles were synthesized using a method developed previously by the Jennifer Shumaker-Parry group. Aminated silica colloids were obtained from the Ilya Zharov group. The gold nanoparticles were adhered to the silica colloids using a method developed for another purpose by the Zharov group. The presence of the particles on the silica colloids was confirmed using both scanning and transmission electron microscopy. The catalytic activity of the gold nanoparticles both with and without adhesion was investigated. It was found that free nanoparticles had significant catalytic activity, in agreement with previous research. Gold nanoparticles attached to silica colloids do not seem to exhibit the same level of catalytic activity as the free particles. It was also found that not all the gold nanoparticles adhered to the surface of the silica particles. Experiments were conducted to determine if there was a critical concentration of silica colloids that would allow for high levels of adhesion of the gold nanoparticles. It was found that only by adding a significant excess of silica colloids to the solution can all the gold nanoparticles be removed from the solution. It was also found that the silica can be saturated with gold nanoparticles by including a small amount of them in a very concentrated gold nanoparticle solution. Further studies for functionalization of the silica colloids and the ability to physically isolate the silica with gold nanoparticles from free nanoparticles are currently in progress.

Benjamin Pound, Utah State University Physical Sciences Carbon Nanotube (CNT) Forests are vertically grown carbon nanotubes. They can be as tall as millimeters, with radii from less than one nanometer (single-walled) to tens of nanometers (multi-walled). Their high surface area to volume ratio provides a unique material system for biosensor applications. However, the CNT surface does not provide covalent bonding sites to many antibodies of interest. One approach is to attach linker molecules with aromatic rings via π-stacking to the CNT surface and activating the linker molecules to bind covalently to specific antibody molecules. Unfortunately, the conventional solution-based functionalization approach often leads to collapse of the CNT forest and hence a significant loss of binding sites. In this presentation we demonstrate that CNTs can be lithographically defined to form various structures that are resistant to liquid-induced collapse. We show that the CNT forest can be functionalized with 1,5-diaminonaphthalene as a linker molecule and its coverage can be characterized by fluorescence spectroscopy.

Alexandra Kent, University of Utah Physical Sciences Prescription drug overdose and abuse is a leading cause of death in the United States. It is a serious issue and has become increasingly problematic as opioids are being prescribed at a higher frequency. For this reason, fast, accurate detection of small drug molecules is crucial. The current standard for use in clinical drug detection is an enzyme-linked immunosorbent assay (ELISA) that uses a series of antibodies to bind to the target drug and enable quantification via a colorimetric output. However, the antibodies used in an ELISA often cannot distinguish between similar molecules. Aptamers are short sequences of DNA that have emerged as a promising alternative to antibodies, as they are generated in vitro, where negative selections can be used to increase target selectivity. These aptamers can be cleaved to make split aptamers that only assemble in the presence of the target small molecule. One inherent problem of this system is the need for split aptamers that are selective for their small molecule targets. While there are many known aptamers, there are only a few known split aptamers that bind small molecules. Separating aptamers with a privileged, three-way-junction structure provides a reliable method to generate new split aptamers.

Jazmin Myres, Brigham Young University Physical Sciences In scan-based array measurements, stationary reference sensors are needed to temporally correlate the different measurement scans and produce coherent complex pressure fields. Because the number of references required increases with the number of subsources contributing to the sound field, an extended, partially correlated source comprising many ill-defined sources can result in significantly increased measurement complexity. A different approach to creating spatiotemporally coherent pressures is demonstrated here. Scan based measurements of a partially coherent line source have been taken in an anechoic chamber. This experimental data has been used to explore “stitching” together a complex pressure field by spatially overlapping measurement scans instead of using separate reference channels. Various methods of stitching have been explored and the most robust method identified. Unwrapping of intrascan phases is first accomplished with a two-dimensional phase unwrapping algorithm. Individual scan positions are then stitched together using median phase differences between multiple adjacent scans to create coherent planes of data. Amplitude-stitching is done by averaging across scans and preserving the integrated squared pressure across the overall aperture. This method has been verified using reference microphones. This stitching method has been applied to scan based measurements of a military aircraft, exhibiting its effectiveness dealing with a partially correlated complicated source. This method works well for low-frequency jet data, where there is not a ground-based interference null creating a physical phase discontinuity. This technique provides direction for efficient experimental design for scan-based array measurements of extended sources. [Work sponsored by ONR.]

Buchanan Kerswell, Utah Valley University Physical Sciences This project is designed to investigate anthropogenic impacts on the geochemistry and physical characteristics of Utah Lake-Jordan River transition zone, in Utah Valley, Utah. The zone has experienced dramatic, multifaceted shifts since European settlement in 1847, especially in recent decades. Our chosen study location is uniquely situated to capture changes recorded in the sediment cores due to land use, nutrient enrichment, vegetation shifts and river dynamics since pre-settlement.

Phillip Lundgreen, Utah State University Physical Sciences By developing a low-noise, high-voltage battery power supply, system noise has been reduced, increasing accuracy of conductivity measurements of highly disordered insulating materials. The method involves a simple parallel plate capacitor setup with the sample sandwiched between electrodes, a voltage potential applied to one electrode, and a measurement device applied to the back electrode measuring current. Previous methods involved use of a commercial power supply with a claimed low noise and high linearity, but with a low AC output ripple. At high voltages (1000 V), however, the noise became apparent in the readings and an unacceptable uncertainty was introduced in our precision conductivity measurements. Through the use of a stable dc battery high-voltage power supply, we were able to reduce noise in current measurements and achieve a more accurate measurement of conductivity for various samples.

Nathaniel Wells, Utah Valley University Physical Sciences Previous research with bottle-shaped thermoacoustic prime movers has revealed hysteresis with transitions to higher modes as the cavity length is varied. A string with an abrupt change in mass density was studied to investigate potentially similar behavior. Three base guitar strings were studied at three different tensions with weights of 25, 30, and 35 lbs. Each string consisted of a “thin side” that was stripped to the stainless steel core and a “thick side” with an outer wrapping of nickel around the core. The strings studied had diameters of 0.65, 0.45, and 0.50 mm on the thin side and 2.14, 1.31, and 1.24 mm on the thick side, respectively. An anchor was attached on one end of a short board with a pulley at the other for hanging the weight. The end of the thick side of the string was attached to the anchor, and the string was guided over the pulley, with the change in mass density occurring approximately 12 cm from the pulley. Measurements were taken after placing a glass jar under the thick end of the string, between 42 cm and the position of the change in mass density, in 3-cm steps. The string was plucked and the dominant frequency was recorded with a microphone at each location. Frequency data is generally consistent with a solution to a 1D wave equation. Preliminary results indicate mode transitions occurring for all strings, with several hysteresis region candidates.

Zachary Anderson, Brigham Young University Physical Sciences Correlation analysis is useful in extracting spatiotemporal relationships between signals and can be used to examine features of near-field jet noise for source properties. Characteristic correlation envelopes determined by Harker et al. [JASA 133, EL458 (2013)] can be used to relate correlation lengths to fine and large-scale turbulent structures. As an extension, cross-correlation shows spatial variation in jet noise and further reveals the transition between short (fine-scale) and long (large-scale) correlation lengths. These analyses are applied to a military jet dataset of a ground based linear microphone array positioned 11.6 m from the jet axis. Correlation analyses over multiple engine conditions and observation directions are reported. In particular, a maximum correlation coefficient greater than 0.5 exists over a range spanning multiple wavelengths in the region of greatest overall sound pressure level at military power.

Mallory Millington, University of Utah Physical Sciences Groundwater in the western United States is a limited and important resource for agriculture, industry, and residents alike. Knowing the movement of groundwater is critical to understanding the potential of groundwater contamination from human activities. While groundwater flow is difficult to quantify, it typically recharges in high elevation and discharges towards lower elevation. The first commercially-approved tar sands mine in eastern Utah is located on a ridgetop in the PR Spring area within the high plateaus on the south rim of the Uinta Basin. To evaluate the potential of groundwater contamination due to tar sands mining a study was conducted to understand groundwater flow in the PR Spring area, specifically the canyon directly south of the tar sands mine called Main Canyon. Water samples were taken from four groundwater springs at elevations ranging from 7040 to 8040 ft in or near Main Canyon. Water quality measurements taken in the field showed that the lower springs exhibited higher conductivity (900 vs. 636 μS/cm) and lower dissolved oxygen (30% vs. 88% saturation) than the higher elevation springs. This suggests that the lower springs have had a greater amount of water-rock interaction and so are chemically more evolved than the springs at higher elevations. SF6 age dating indicated that the high elevation springs are younger than the lower elevation springs, 5.5 vs. 16.0 years since recharge respectively. The field parameters and SF6 age data all indicate that higher elevation springs are younger and less chemically evolved than the water at lower elevations. This indicates that the springs in Main Canyon are sourced from local recharge at the ridgetops. Given these findings the tar sands mine should consider taking preventative measures to protect groundwater resources.
