Computer Science and Information Systems Breast cancer is the leading cancer killer among women in the state of Utah. According to the Center for Disease Control (CDC’s) Behavioral Risk Factor Surveillance System (BRFSS), Utah has the second lowest mammogram rate in the nation. Mammograms reduce breast cancer mortality rates by increasing early detection of the disease when it is still curable. A quick binary logistic regression of the data completed for this presentation suggests that there at least three factors that are statistically significant for not receiving a mammogram: lack of a health plan, infrequent dentist visits, and age. Some counties including Millard, Summit, Tooele, Sanpete, and Uintah appear to be statistically significant factors. Other counties have low mammography rates, but too little data to be statistically significant including Beaver, Wayne Garfield, Paiute, Daggett, and Rich. By identifying patterns and analyzing correlations between variables, we may begin to understand why Utah women are not taking advantage of early detection in the form of mammography screenings. Our research has the potential to improve the attitude with which the topic of mammography is approached, and in doing so, save lives.

Jenna Jackson, Brigham Young University Psychology We examined the effect of social separation stress and serotonin transporter genotype (5HTT) on behavior during mother-infant (MI) reunions using infant rhesus macaques. Based on previous studies, we predicted that infants and mothers who posses the less efficient short (s) allele would display more anxious and aggressive behaviors in both their relationship and also within the larger social group. MI behaviors were recorded during a reunion period after being separated for five days from their mothers. Subjects were 140 rhesus macaques that were tested in one of two separation conditions: mother removed from the social group with the infant left behind, or the mother and infant were each housed alone in single cages. Time spent in behaviors that characterize MI and peer relationships were recorded as dependent variables, while genotype was used as the independent variable. Results showed that MI interactions were especially affected if both the mother and the infant possessed the Ls genotype. Moreover, infants with the Ls genotype also displayed less social contact with other group members, and higher rates of aggression with their peers. Our findings suggest that when both the mother and the infant possess the 5HTT short allele, the MI relationship is strained, showing higher levels of stress and that peer bonds are also affected negatively by the Ls genotype. To the extent that our findings generalize to the human condition, they suggest that the 5HTT genotype influences environmental conditions to influence the mother-infant bond and other social interactions.

Paul Chidsey, Brigham Young University Chemistry and Biochemistry It has been reported that an estimated 11% of women in the population have undiagnosed endometriosis, emphasizing the need for early detection tests and treatment options. Diagnosis is typically determined through an analysis of symptoms, including painful menstrual cycles, pain in the lower abdomen, and prolonged menstrual cramping. Diagnosis is further confirmed through invasive procedures such as transvaginal ultrasound and pelvic laparoscopy. Serum proteomic studies in which small biomolecules and peptides are analyzed for biological significance in endometriosis cases and controls can lead to the discovery of novel methods whereby the disease is detected and eventually treated earlier in development without the need of invasive procedures. Comparative analysis of cases and controls through mass spectroscopy has led to the discovery of novel biomarkers capable of correctly identifying individuals with endometriosis. Further pursuing this study will allow for a greater understanding of the genesis of the disease, eventually uncovering the mechanism whereby endometriosis develops.

Devon Blake, Brigham Young University Chemistry and Biochemistry G proteins play a vital role in cellular signaling. It has recently been shown that the nascent G polypeptide requires the assistance of phosducin-like protein 1 (PhLP1) for proper folding and formation of the G beta gamma dimer. This mechanism is derived from cell culture experiments and structural data, but until now had yet to be tested in vivo. We tested PhLP1 function in vivo using retinal rod photoreceptor-specific PhLP1 conditional knockout mice. Electroretinogram analyses of these mice showed a dramatic decrease in light sensitivity of rod photoreceptors. Consistent with this finding, the expression of all subunits of the photoreceptor G protein was reduced by 80%. This decrease was reflected in a similar decrease in the amount of G beta gamma dimers. All of these in vivo results are consistent with the hypothesis that PhLP1 is required for G beta gamma assembly and G protein signaling.

Brennan Young, Utah State University Geology Thermal springs in northern Utah and southeastern Idaho mostly lie near active or inactive Basin-and-Range normal faults. They are dynamic systems, and the character of some has changed drastically since work as early as the 1980’s (Blackett and Wakefield, 2002; IDWR, 2001). We examined and sampled 60 thermal springs and most samples met criteria for cation geothermometers, or mathematical-geochemical tools used to estimate the maximum temperature of hydrothermal reservoirs. Of the 60 springs, 51 met criteria for the Na-K-Ca geothermometer and the remaining nine springs did not meet the criteria for the K-Mg, Na-K, Na-K-Ca, or Na-K-Ca-Mg cation geothermometers used in this project (Fournier and Truesdell, 1973; Fournier and Potter, 1979; Giggenbach, 1988). Of those 51 springs, only one is considered to be in partial equilibrium with the thermal reservoir, and estimates a reservoir temperature of 79°C (Giggenbach, 1988). Though the majority of springs exhibit a chemical signature of having mixed with shallow groundwater (Giggenbach, 1988), the Na-K-Ca geothermometer gives the most reliable results for springs in northern Utah and southeastern Idaho, but only for springs with surface temperatures exceeding 30°C and with greater than 1000 ppm total dissolved solids (TDS). Geothermometer results for these springs yield reservoir temperature estimates between 193 and 249°C.

Daniel Gray, Utah Valley University Physics Mini black holes (BH) of various mass could be left over in space from the early expansion Big Bang phase (so called primordial BHs). As a result of interaction of those BHs with interstellar hydrogen they could form a bound system with an electron or a proton (or both). What would such system look like? Would it be stable, metastable, or would BH quickly consume the orbiting particle? How much is life time of such “gravitational atom”? If such system is stable then what is the size of it; how much is the bonding energy of its ground state (=ionization potential energy) and how much are the energies of its exited states? Are those atoms “gravitational atoms” observable? What other properties do they have? Based on known physics we try to analyze the behavior of such exotic systems and answer the above questions for black holes of various masses.

Ryan Smith, Brigham Young University Geological Sciences Bhutan, a remote country in the Himalayas, has an underdeveloped economy that relies heavily on hydro-electric power and agriculture. Glacial lake outburst floods, or GLOFs, threaten both of these sectors of their economy. More importantly, they threaten human lives. In this study, I will estimate the increase in volume of the most rapidly growing glacial lakes in the Bhutanese Himalayas and investigate potential causes of their growth. In addition, I will develop a simple model to simulate the flooding effects of a GLOF on downstream cropland and villages.

Samuel Leventhal, University of Utah Physics The uncertainty existing within the scientific community as to why quantum mechanics (QM) behaves as it does comes from the fact there exists no mathematically sound approach for deriving the postulates of QM. It is the purpose of our research to present a derivation for the postulates of QM through the theory of Scale Relativity (SR), followed by a search for physical signatures of SR in the mechanics of celestial bodies. The construction of SR is based on an extension of the relativity principle to scale transformations coupled with a loss of differentiability. Our first paper presents the derivation of QM through scale relativity. During the SR derivation we also show fundamental qualities of QM, such as the presence of complex numbers in state functions. Lastly, the seemingly unrelated behaviors between relativity and quantum phenomena are shown a single mathematical formulation, only to change form due to scale. The new resolution variable within the adapted Schrodinger equation allows it to become applicable to macroscopic scales allowing us to look at large scale mechanics for signs of SR. Gravitation being scale invariant leads it to be a perfect candidate for experimental purposes. Our second paper investigates whether or not celestial bodies, formed by chaotic gravitational structuring, obey the properties of a Schrodinger equation dependent on the Keplerian potential. If so SR implies solar systems would form along probability distributions predicted by the square magnitude of the Schrodinger-Keplerian wave equation. In theory a planets probability distribution would depend on discrete variables, denoted orbital rank, n=n. In search for SR it is sufficient to see if planets tend to have orbital ranks near integer values. We start by calculating the orbital ranks within various solar systems, followed by testing whether the accumulation of planets’ rank near integer values is a probable event. To test this we take the squared difference between the calculated rank and the nearest integer. As a result we are able to test how likely orbital structuring will be discrete. Our results show a strong certainty that orbital rank is likely to accumulate near integer values.

Sally Hansen, Utah Valley University Chemistry Cytochrome c oxidase (CcO) or complex IV is the terminal component of the electron transport chain. In eukaryotic organisms, CcO is composed of 12-13 subunits. The core of eukaryotic CcO contains three mitochondrially encoded subunits that comprise the catalytic core of the complex and several gene products encoded for by the nucleus (1). Essential to the redox function of CcO are several critical cofactors: two hemes and two copper centers (2). The crystal structure of CcO has led us to several insights about its structural components and catalytic activity (3). However, a large set of nuclear gene products are essential for CcO activity that are not part of the structural machinery of the complex (4,5). These components have been implicated in various stages of CcO assembly including, heme processing and insertion (6), CuA and CuB site delivery and insertion (7), subunit processing and subunit assembly (8,9). Among them are well characterized CcO assembly factors that involve the biogenesis of the CuA and CuB sites in CcO. Sco I, Cox17, Cox 11 and Cox23 are all essential to CcO activity and have properties that appear to be critical to the maturation of the CuA and CuB sites(10-13). Cmc4 appears to be involved in cytochrome c oxidase biogenesis. Peroxide phenotypes have been linked to cytochrome c oxidase assembly (14). Saccharomyces cerevisiae strains lacking CMC4 were found to exhibit peroxide resistance when compared wild type parental stains. Resistance was seen in liquid culture and in media containing glucose and glycerol. These results may indicate that cytochrome c oxidase assembly is altered in CMC4 deletion stains.

Natascha Knowlton, University of Utah Chemistry The chemical derivatization of oxide surfaces (silica, alumina, glass) is critical to the development of separation media, sensing surfaces, or biocompatible interfaces. Presently, there are few analytical methods that allow the detection and characterization of functionalized monolayers on these surfaces. Raman scattering spectroscopy can provide useful structural information in the form of vibrational spectra of molecules of interest, and it is compatible with oxide substrates. Raman scattering, however, is a very weak effect so that its application to detecting monolayers is challenging. In this work, two approaches to detecting and characterizing molecular layers on oxide surfaces with Raman spectroscopy are compared. First, gold colloidal nanoparticles are deposited onto the surface of interest, which enhance the Raman scattering near the gold surface by surface-plasmon resonance. This technique is suitable for ex situ analysis of monolayers on planar surfaces. Secondly, monomolecular layers can also be detected by Raman scattering on porous oxide supports such as alumina or silica without any optical enhancement due to the very high surface area of these materials. Detection in porous particles is compatible with in situ monitoring of surface derivatization reactions. These two methods are compared for monitoring of reactions of silane-coupling agents and their subsequent functional group transformations on glass and silica surfaces.

Alyssa Brown, Southern Utah University Physical Science Coal Creek is a perennial stream that runs through Cedar City, Utah and drains into Rush Lake. The basin is a closed basin, meaning that most of the surface water will eventually become ground water, the main source of drinking water for Cedar City. Because of the increase of urbanization of this region in par- ticular, there is a higher probability of pollutants entering the water source and greatly affecting the quality of the drinking water. Most pollutants are characterized as nonpoint source pollution, which is defined by the Environmental Protection Agency (EPA) as, “land runoff, precipitation, atmospheric deposition, drainage, seepage or hydrologic modification” and is the leading cause of water quality problems (Environmental Protection Agency, 2012). Common sources of land runoff, as defined by the EPA, include septic waste, lawn and garden fertilizers, improperly disposed chemicals, automobile fluids, vehicle emissions, and road deicers (Environmental Protection Agency, 2012). In order to characterize the pollutants found in samples and determine the concentration of ions of interest, ion chromatography was used. By determining the identity and concentrations of particular ions, the presence of nonpoint pollution, and the source, may be determined. This study may lead to better indications of where major sources of drinking water pollutants are originating, illustrating the effect that urbanization and rapid population growth have on the quality of both surface and ground water. This will allow better characterization of pollutants and pollution sources in the future.

Joshua Jeffs, Utah Valley University Chemistry The electron transport chain (ETC) is a system within a cell that couples electron transfer between a donor and a receptor. The ETC is made up of several components, specifically: complexes one through four, a coenzyme Q, and a cytochrome complex. Cytochrome C oxidase (CcO), also known as complex IV, uses electrons and H_ ions to reduce molecular oxygen to water. CcO is made up of several subunits or proteins that are responsible for the function of CcO. The creation of CcO involves multiple steps that include many different gene products or proteins. (3) Of these proteins several are from a specific type of family called cysteine-X _-cysteine motifs (twin CX_C). The cysteine residues in the cysteine pairs are each spaced by nine residues. The best characterized protein of this group is Cox17, a copper-binding protein that plays a role in copper transfer to CcO. There are 14 potential proteins that are twin-Cx_C motifs (1). There were four knock out strains that showed resistance when plated on YPD with varying concentrations of hydrogen peroxide: 0.010%, 0.014%, 0.018%, and 0.022%. Strains lacking CMC4, MIC14, MIC17, and PET191 all showed resistance to hydrogen peroxide compared to the parental strain. Strains lacking MDM35 and COX23 showed sensitivity to hydrogen peroxide. These result may indicate a tie to impaired or incomplete cytochrome c oxidase assembly.

Rachel Nydegger, Utah State University Physics Multi-messenger astronomy employs both electromagnetic and gravitational-wave detectors to paint a richer picture of celestial objects, providing more depth and information. The interferometers utilized for gravitational-wave observations receive input from very broad fields of view on the sky, typically a few square degrees. To have simultaneous electromagnetic observations (typically less than one square degree) requires innovative techniques for the telescopes to find the origin of radiation. One idea is to “tile” the view of the interferometer, using multiple telescopes to simultaneously point at different areas of the field to observe the source. One difficulty of this observing paradigm is distinguishing random electromagnetic variable sources from a gravitational-wave counterpart. To better understand this problem, this project repeatedly observes a single field on the sky. Each observation is analyzed to count the number of sources that appear in the field as a function of brightness. Repeating this process over time will yield the frequency of random optical transients, as well as characterize the population and brightness distribution of variables in the field. Future work will extend this observation campaign to cover different galactic latitudes.

Kelby Peterson, Utah State University Physics The State of Utah Space Environment & Contamination Study (SUSpECS) experiment flown on the Materials International Space Station Experiment 6 (MISSE-6) was an experiment designed to examine the consequences of the space environment on various materials used in space-component design. SUSpECS was comprised of approximately 180 samples that were suspended from the side of the International Space Station (ISS) for 18 months and returned to allow for pre- and post-flight comparisons. The sample with the most evident changes was a thin film of polyethylene terephthalate (PET) MylarTM coated with Vapor Deposited Aluminum (VDA). The post-flight analysis showed evidence of atomic oxygen erosion of the VDA layer, UV-induced discoloration of the polymer, and a crater created by a micrometeoroid impact. This presentation focuses on the UV-induced discoloration and laboratory tests to simulate these effects. The UV tests expose similar polymers to varying intensities of vacuum UV radiation from deuterium lamps over a condensed time span and quantify the discoloration of the polymers through comparison of the UV/Vis/NIR reflection spectra. The results from the UV simulation are used to determine the approximate time period of the UV exposure for the SUSpECS sample and in turn the erosion rate of the VDA layer.

Cathy Crawford, Utah State University Chemistry and Biochemistry In the spirit of many chemistry instructors’ longstanding interest in making teaching labs less “cookbook-like” and more research-driven, we recently restructured our second-semester sophomore organic chemistry lab to include a synthesis project that was chosen, designed, and carried out by students. Students were given the incentive of co-authorship on any publications resulting from their work. This led to the development of total syntheses of JBIR-94 and JBIR-125, new antioxidative/anticancer compounds with radical-scavenging potencies comparable to those of a-tocopherol, the active constituent in Vitamin E. Our presentation will summarize our progress and findings, and includes our progress on bioactivity studies conducted on the JBIR’s and their synthetic precursors.

Alyssa Brown, Southern Utah University Physical Science It has been long debated whether early astronomers could truly see any detail during their first observation and rough sketches of the satellites of Jupiter. Many have argued against the accuracy and validity of such drawings, claiming the lack of technological advance led to rough hewn and mediocre drawings with little evidence of these individuals having truly seen these satellites. Through our research, we hope to prove validity in those early sketches based on current knowledge. By converting the dates and times each early sketch was created into Julian Calendar days, then using the date obtained to calculate the position of each individual satellite of Jupiter, as well as the face that was approximately facing Earth at the time the sketch was made, we can compare current images to those previously obtained sketches. By analyzing the sketches for determining features as well as the relative location of those features in relation to their approximate location on the satellite face the astronomer was most likely observing, we can either validate or disclaim these early sketches. This experiment will provide beneficial insight into the accuracy of primitive sketches made centuries before more detailed information was discovered about the celestial bodies that continue to fascinate us. The information gained from this experiment may even lend a greater knowledge and understanding of how to study these celestial bodies, since if the information presented by these early sketches were accurate, we could potentially reevaluate the manner in which we currently conduct our present observation.

David Pease, Utah Valley University Physics Transition regions to higher resonant modes of a bottle-shaped thermoacoustic prime mover (neck: 5.39 cm long, 1.91 cm ID; variable cavity with a sliding piston: up to 38 cm long, 4.76 ID) were studied. As the piston is extended, lengthening the cavity, starting from the neck, a transition of the dominant frequency from the fundamental to the first overtone occurs. However, when the length is then shortened, transition back to the first mode does occur at the same piston position, revealing hysteresis. Within the window of hysteresis for the cavity length, either state of the fundamental or first overtone is possible. Transition regions to higher modes continue as the length of the cavity is increased. The position and width of the hysteresis was studied for the first two transition regions as a function of input power and stack volume filling factor. Input powers studied were between 12.0 and 16.5 W and volume filling factors for the stack were about 3.0, 3.7 and 4.9%. The transition regions occurred with cavity lengths between 12.6 and 14.0 cm for the first transition and between 25.0 and 27.8 cm for the second transition. Preliminary results indicate that the transition region occurs shallower in the cavity and the hysteresis widens as the input power is increased. The hysteresis is wider for the second transition region. Decreasing the stack mass causes an increase of the hysteresis width, but has no strong effect on the hysteresis depth.

Ben LaRiviere, Utah State University Geology The DOE-funded HotSpot Project out of Utah State University has collected a more than mile-deep core from the central Snake River Plain, Idaho, to study the geologic history of the area. The core consists mostly of volcanic basalt, however 16 sediment layers have been identified and sampled between the basalt-flow layers. These layers of sediment are the key to understanding environmental conditions on the Snake River Plain between basalt flows. The sediment was sampled in 25cm increments and the grain size of the sediments were examined in a laser particle size analyzer to better understand depositional conditions on the snake river during the past 5 million years. The analysis revealed that the majority of the sediment was deposited as windblown silt with several fluvial deposits.

Lisa Heppler, Brigham Young University Chemistry and Biochemistry Solid breast tumors contain heterogenous microenvironments where tumor cells are often exposed to metabolic stress (e.g., hypoxia due to poor blood supply). Such environments select for tumor cells that can adapt metabolically to survive, while other cells fail to adapt and undergo cell death. The survival of cells through periods of hypoxia can promote chemoresistance and metastasis (1). Thus, it is critical that we develop therapeutic strategies to enhance metabolic-stress-induced tumor cell death. One promising strategy is the modulation of lysine acetylation pathways by HDAC inhibitors that potently pro- mote cell death in response to various stimuli, including hypoxia/glucose withdrawal. Given the relatively non-specific nature of chemical HDAC inhibitors, the precise acetylation-regulating enzymes and pathways that govern cell death in these settings have yet to be fully elucidated. Our goal is to identify the cellular factors that link acetylation to cell death in response to hypoxia and other metabolic stresses, with the hope that such factors could be exploited therapeutically in cancer. Previous studies have implicated protein lysine acetylation in the coordination of cellular metabolism to the available nutrient supply (2). In line with this idea, our preliminary data suggest that lysine acetylation pathways dictate whether breast tumor cells survive (through metabolic adaptation) or die in response to hypoxia and glucose deprivation. Moreover, we have observed that general increases in protein lysine acetylation precede the activation of pro-apoptotic caspases in response to these stresses. In addition, our proteomics efforts have shown that breast tumors that are sensitive to hypoxia/glucose withdrawal exhibit significant increases in acetylation across the proteome, whereas resistant cells show very little change. Together, our data suggest that lysine acetylation pathways play a role in metabolic adaption and survival under conditions of hypoxia/glucose withdrawal. We are currently using an RNAi approach to target all known deacetylases, acetyl-transferases, and metabolic enzymes that modulate acetylation (e.g., acetyl-CoA synthetase) in order to identify the specific acetylation-regulating factors that govern tumor cell susceptibility to metabolic stress.

Kent Hartley, Utah State University Physics Faraday cups provide a simple and efficient apparatus to measure the absolute magnitude of charge particle fluxes, and with the addition of a retarding field analyzer and defining apertures the capability to determine the energy and angular distributions of the fluxes. Through careful design of the electron optics, a Faraday cup can be tailored to meet specific requirements for detector size, minimum detectable flux, collection efficiency, absolute accuracy, energy discrimination, and angular resolution. This work explores design concepts through electric field and charged particle trajectory simulations, theoretical analysis, and evaluation of experimental prototypes to develop compact, high efficiency Faraday cups capable of a range of energy and angular resolutions. The designs rely on high efficiency Faraday cups coupled with grid-free Einzel lens energy analyzers for nearly energy-independent determination of absolute fluxes. We also review specific designs and applications of these Faraday cup detectors to electron emission and transport studies, spacecraft charging applications, and electron beam characterization measurements done in conjunction with various projects conducted by the Materials Physics Group.

Beau Hilton, Brigham Young University Physics/Acoustics The Udu drum, sometimes called the water pot drum, is a traditional Nigerian instrument. Musicians who play the Udu exploit its aerophone and idiophone resonances. This paper will discuss an electrical equivalent circuit model for the Udu Utar, a specific type of Udu, to predict the low frequency aerophone resonances and scanning laser vibrometer measurements to determine the mode shapes of the dominant idiophone resonances. These analyses not only provide an understanding of the unique sound of the Udu instrument but may also be used by instrument designers to create instruments with resonance frequencies at traditional musical intervals for the various tones produced and to create musical harmonic ratios.

Joseph Jensen, Utah State University Physics The earths ionosphere is very important in our everyday life. During large solar flares the ionosphere expands to the point of disrupting communications from GPS, military, and commercial communications satellites, and even radio blackouts can occur. The EVE instrument on the SDO satellite has given unprecedented spectral resolution for the Extreme Ultraviolet (EUV) spectrum with a time cadence of 10 seconds. This has made it possible to analyze flare spectra as never before. Using the Time Dependant Ionospheric Model (TDIM) we have input this new spectral data for large solar flares and analyzed the effect on the ionosphere. We take as a test case the X1.6 flare on March 9, 2011. Even this minor X-class provides insight into how the ionospheric layers respond differently to solar flares.

Jacob Wright, Utah Valley University Physics Dissonant overtones of closed bottle-shaped thermoacoustic prime movers are discussed. The resonator consists of two concentric cylinders with differing cross-sectional areas, closed at the outer ends. The condition for resonance results in a transcendental equation, which is solved numerically. The neck and cavity behave as coupled resonators, where the neck is a quarter-wave resonator and the cavity is a half-wave resonator. A variable cylindrical cavity with a sliding piston was constructed to study the nature of the device as the cavity length is varied. The stack is located in the neck region and the length and inner diameter of the neck are 5.39 and 1.91 cm, respectively. The inner diameter of the cavity is 4.76 cm and has a maximum length of 38 cm. The dominant mode of operation depends on the length of the cavity, favoring successively higher modes as the cavity length increases. The volume filling factor of the stack material was varied from 2 to 5% to determine whether the amount of stack material affects the transitions. These filling factors were selected to yield hydraulic radii comparable to the thermal penetration depth for the highest and lowest possible fundamental frequencies of the system. The transition to higher modes occurs roughly where the higher mode overlaps with the fundamental frequency of the neck region, and is independent of the stack filling factor. With the given dimensions, three transitions to higher modes were observed, with frequencies consistent with the model.

Michael Strange, Utah State University Geology For the past century, the standard technique used to interpret soft-tissue preservation in the fossil record has been the camera lucida drawing. A new technique called False Color Treatment (FCT), which uses digital photography and photo manipulation, shows an increased ability to not only interpret soft-tissue features but also identify trace amounts. Hyolithids from the Cambrian of northern Utah were used to test the capabilities of FCT. Results were then compared to camera lucida drawings of the same specimens. Comparisons show the camera lucida drawings missed areas of soft-tissue that FCT found. Depending on the specimen, and the type of preservation, this disparity in interpretations can increase or decrease. Hyolithid specimens from the Spence Shale show an odd form of Burgess Shale Type (BST) preservation which makes them particularly well suited for FCT manipulation. Overall, False Color Treatment provides an informative and aesthetic method for interpreting soft-tissue fossils with BST-like preservation.

Carolina Silva, Jasmin Alves, Katrina England, Courtney Hammond, and Ethel Tackle-Yarbol; Westminster College Psychology Bullying among adolescents is a common problem that deserves attention. Youth City, a multi-site after school youth program in the Salt Lake City area catering to youths ages 8-13, expressed an interest in learning more about bullying experiences in their attendees with the aim of developing a program for intervention and prevention. We partnered with Youth City to develop the current project, the goals of which were twofold: (1) to measure the prevalence and types of bullying experienced by 53 youths attending one Youth City site (our participants) and, (2) to work with the youth and the site coordinator to develop a bullying intervention and prevention program. Participants completed a modified version of the Olweus Bully Victim Questionnaire, in which 31 behaviors of bullying were assessed. Behaviors included examples of physical bullying, relational bullying, cyber bullying, and bullying due to one’s ethnicity or sexuality. Participants were asked to report whether each behavior had ever been done to them (victim role), done by them to another (bully role), or witnessed by them in the role of bystander. Results showed that the participants had experienced many of the behaviors as either victims, bullies, or bystanders. The second step was to conduct focus groups in which participants were asked more about their bullying experiences and what they felt could be done to more effectively intervene and prevent bullying. Transcripts from the focus groups were analyzed for emergent themes. These themes, combined with input from staff and information gleaned from research into other programs, were used to draft a bullying intervention and prevention plan to be implemented at one Youth City site in the coming school year.

Scott Ploharz, Weber State University Psychology A pilot study conducted in spring of 2012 by the same researchers, suggested that sexting, or the sending of text or picture messages containing sexual content is common among young adults ages 18-30. This pilot research suggests that there were differences in personality and relationship satisfaction among those who engaged in sexting and those who did not. This current study further examines the effect of sexting on individuals and their relationships, as well as the reasons individuals may choose to engage in sexting. This study examines personality traits that may be related to engaging in sexting using both the Big 5 personality inventory and the Narcissistic Personality Inventory (NPI). The relationship between engaging sexting and relationship satisfaction is measured using the Revised Dyadic Assessment Scale(RDAS). To measure the effect on the individual, along with providing a possible explanation for sexting, self-esteem will be measured using Rosenberg’s RSE. Previous research suggests adult attachment style as a possible method of explanation as to who engages in sexting and the reasons for the behavior. Attachment style is measured using the Experiences in Close Relationships Revised (ECR-R) and the Experiences in Close Relationships Revised Structures (ECR-RS). Analysis of the data is expected to be completed by January 31st 2013. Results are expected to show that those with an Anxious or Anxious/Avoidant attachment style are more likely to sext. It is also expected that there will be a small positive correlation between the personality trait extroversion and sexting. It is also expected that specific domains of narcissism and lower self-esteem scores, will relate to engaging in sexting. There is also expected to be a negative correlation between sexting and relationship satisfaction.

Scott Ploharz and Britaini Delbo, Weber State University Psychology Youth or Peer Courts are diversionary programs designed to lower recidivism and re-offense rates among youth offenders. These programs focus on lowering risk factors and enhancing protective factors among the youth they serve. This study will look specifically at the Youth Court based in Layton Utah. Using a projected sample of 280 youth offenders over a 4 year period, the efficacy of this program will be evaluated. Efficacy will be measured by the rate of re-offense compared to youth in the traditional juvenile justice systems who have committed similar offenses. Analysis will also be performed using participant surveys, to determine which risk and protective factors are associated with re-offending. We anticipate completing this project by January 1st 2013.

Dexter Thomas, Westminster College Psychology When someone is the victim of a beating, rape, or murder, one might expect that most individuals would recognize the innocence of the victim. Surprisingly, research suggests many people assign blame to innocent victims (Dalbert, 2009; Lerner & Simmons, 1966). The “Just World” hypothesis proposes a possible explanation for this puzzling phenomenon. Belief in a Just World implies that good things happen to good people and bad things happen to bad people. Previous research has found a relationship between belief in a just world, victim blaming, and other beliefs such as homophobia (Glennon & Joseph, 1993; Anderson, 1992). The present experiment extends upon this area of research. We examine transphobia, belief in a just world, and victim blaming. Three hundred and forty-two participants ages 18-72 were recruited from within the United States. Participants read a scenario in which an individual was the innocent victim of a beating. Participants were randomly assigned to one of two conditions; in one condition, the victim was transgender, in the other condition, the victim was not. Participants then completed questionnaires measuring victim blame, transphobia, and belief in a just world. Results showed that transphobia positively correlated with belief in a just world. Additionally, a positive correlation was found between victim blaming and transphobia for all victims, transgender and non-transgender. However, when controlling for levels of transphobia, belief in a just world was no longer correlated with victim blaming. These results suggest that transphobia is related to belief in a just world and that transphobia, separate from belief in a just world, is related to increased victim blaming even for victims who are not transgender.

Antoinette Kingsford, Weber State University Psychology The type of professor a student selects for a college course can impact the quality of learning and success in the course. Information about the traits and qualities of professors is limited to word of mouth and Internet sites that allow for biased ratings of professors. The validity and quality of information obtained via online professor rating websites, like RateMyProfessor.com (RMP), is often called into question in academia. A study to assess the validity of RMP was conducted with 127 Weber State University students from introductory psychology classes. The participants completed an online survey using the RMP rating scale for professors, and they also completed the College of Social Sciences professor evaluation survey. They were also asked questions regarding RMP usage, professor traits, and sources they used to find information about professors. The findings of the study indicated that students were using RMP more frequently than word of mouth from friends to obtain useful information about professors. The most meaningful traits in professor selection were Clarity and Overall Quality, not necessarily Easiness and Attractiveness. Also, there were no significant differences between gender and professor trait importance, and the validity of RMP was highly correlated to the Student Evaluation of Weber State Psych 1010 Professors.

Trevor Hicks-Collins, Weber State University Psychology Austistic Spectrum Disorder (ASD) is an increasingly prevalent disorder, with approximately 1 of every 88 children in the United States diagnosed with the disorder. Several factors can exacerbate autistic symptoms in ASD children, including environment, diet, and sleep. Sleep problems in children with ASD’s occur more frequently than in non-ASD children, and their effects could be even more detrimental. The sleep literature in non-ASD children is clear about how sleep deficits adversely affect behavior and cognition, but there is little research to indicate the effects of sleep deficits on ASD children. This study was designed to assess the effect of sleep quality and quantity on ASD symptoms. The participants were children, ages 5-8, who were rated on the autistic spectrum. The children’s sleep was assessed using Actigraph monitors, which provided an objective measure of sleep quality and quantity. The children wore the monitors each night for one week. Also, parents and teachers kept daily records of the children’s sleep quantity and autistic behaviors, reporting both good and bad behaviors. A MANOVA was used to assess the effect of REM sleep, duration of sleep, and number of interruptions on autistic symptoms reported by parents and teachers. Results indicate that the amount and quality of REM sleep (both short-term and long-term) affects the frequency of autistic symptomology in children. In addition, results demonstrate that parents’ perceptions of sleep duration in their children is greatly distorted. Parents believe that their children are getting much more sleep than they actually are. Helping parents and teachers understand how important sleep is in affecting autistic symptomology can help modify behaviors. Studies like this are instrumental to providing us with information to better understand one of the fastest growing disorders affecting children today.

Nicholas Gailey, Westminster College Psychology For over seven decades organizational scientists have extensively studied the happy-productive worker thesis, which assumes that a happy worker is a productive worker. Previous research in the field has focused on the relationship of a worker’s own happiness with their productivity. However, uncertainty remains today as to the link between managerial psychological well-being and their employees’ productivity. The purpose of the current study is to find a correlation between managerial psychological well-being and employee productivity. Thirty managers from two manufacturing facilities participated in the study and responded to two different measures of psychological well-being. Productivity data from one hundred employees underneath the managers were also collected daily over a period of three weeks. Results, strengths, and limitations of the study will be discussed along with its implication for future research and practice in the field of industrial/organizational psychology.

Eric McKinney, Weber State University Mathematics We consider a list of properties of isomorphic simple graphs and the use of these properties as quick tests to show nonisomorphic relationships. We compare advantages of tests, and list these in order of efficiency. We consider a nonisomorphic test using cospectral graphs with its drawbacks. And lastly, we observe an algorithmic approach showing two graphs are isomorphic through efficient adjacency matrix reordering techniques.

Sean Groathouse, Westminster College Mathematics Strategies for the Colonel Blotto game common in human play are generalized and compared through computer simulation. Furthermore, a variation on the game where the opponent’s resources are unknown is introduced, and differences between the variation and the classic game are explored with simulations on the common human strategies. Another variation on the scoring of the game is introduced and analyzed through simulations and a partial solution to the Nash equilibria in the two-front case.

Mimi Marstaller, University of Utah Economics During the Progressive Era that stretched roughly from 18771928, the United States faced the rising costs of industrialism. As corporate capitalism expanded and a national market replaced local economies, the role of the federal government changed to include mitigating collective costs by providing public goods. The Progressive Era represents the U.S.’ first national discussion on the role of the state in an industrialized nation. The nation, newly linked by economic ties, faced a collective action problem. I use this historical backdrop to examine economic theories on how societies manage the costs of capitalism. I look at scholarship on collective action, spontaneous order, self-regulation and enforcement within economic systems, and explore how the Progressive Era exemplify or refute the theories on social and economic behavior. I trace the emergence of a national market from pre-industrial, local economies, and examine how in the national context citizenship, the newly powerful nation state and standardized treatment of collective costs played an essential role in establishing the market as the central motivating factor of 20th century American culture. The institutions supporting citizenship and facilitating market participation bolstered capitalism but also required significant oversight by the regulatory bureaucracy established during the Progressive Era. While mainstream economic theory minimizes the role of class interests and power dynamics by assuming freedom of contract and costless enforcement of property rights, recent work in economics invokes sociology and history to understand the barriers to collective action. Today’s most illuminating theories revive the thought processes of the early, classical political economists, and I use the Progressive Era to explore the extent to which their theories on collective cost management describe the case of U.S. industrialization.

Joshua Blume, Utah State University Economics and Finance Studies of expatriates in a number of industries have suggested that acculturation plays a role in how individuals re-adapt to their home country after working abroad. This study applies acculturation and repatriation frameworks to returned Mormon Missionaries (who have also spent significant time away from home and family). Qualitative and quantitative results suggest that re-adaptation to home, family and school are affected in part by cultural components of the mission experience. Recommendations are made to assist “expatriate missionaries” in the re-acclimation process.

Andy Thompson, Utah Valley University Academic Affairs The effectiveness of relationship education, especially among predominately young college students, has been a topic of great interest. Given the diversity of family outcomes, more young individuals seek out help for their relationships. Past studies involving relationship education programs have showed that such programs are beneficial (e.g., Halford, et al., 2003). Improvement in couple communication skills was one effect of couples participating in these programs, and even increased relationship satisfaction in some instances (Halford, et al., 2003).

Whitney Evans, Brigham Young University Communications The United States adopted a freedom of information law earlier than the United Kingdom, but the latter has surged ahead with its adoption of an Information Commissioner’s Office, well equipped to handle complaints and mediate in complex situations. This article delves into the attitudes of those who are intimately involved with freedom of information laws: journalists, lobbyists, campaigners, advocates and government officials. This qualitative research showed a similar attitude at a government level in both countries, namely, a hesitance of government officials to warm up to the law. The Information Commissioner in the United Kingdom and the Office of Government Information Services in the United States are essentially limited to recommendation and mediation services. The United States, initially progressive in its open government laws, has lagged behind many other nations in terms of disclosure. Because the law is nearly 50 years old, the Freedom of Information Act here is often taken for granted. Complacence, rather than outright defiance, obstructs successful implementation of this law. The United Kingdom has the lingering legacy of an Official Secrets Act obstructing what would otherwise be a clean slate on which to build their government disclosure laws. The key to successful utilization of freedom of information laws in both countries lies in a shift in each country’s culture, instigated by a marked change in the stories being told.

Michael Alexander, Utah Valley University Academic Affairs The Tintic Mining District is located in central Utah on the eastern edge of the Basin and Range Province. This area experienced significant hydrothermal alteration associated with volcanism in the early Cenozoic Era. This hydrothermal alteration was productive of sulfide ore deposition along fissure veins, including ores of copper, gold and silver. Previous aeromagnetic surveys showed that porphyry copper assemblages are associated with mappable anomalies in the Earth’s total magnetic field. The magnetic anomalies were interpreted as resulting from buried intrusive igneous rocks associated with the porphyry copper assemblages. The objective of this research is to map buried fissure veins on property owned by NorthStar Mine using a ground-based survey of anomalies in the Earth’s total magnetic field. This study will be the first geophysical mapping of fissure veins in this area. Previous work by the author and other Utah Valley University students showed that total magnetic field anomalies could be used to map halloysite clay deposits, the copper sulfide deposits associated with buried basaltic dikes, and a wide variety of igneous rock bodies including buried bodies of quartz monzonite, rhyolite and tuff. Because the igneous rocks are considered to be the source of hydrothermal fluids, further mapping of the distribution of igneous rocks could give some insight into the migration of fluids that deposited ore in fissure veins. The ground-based magnetic survey will be carried out using the Geometrics G-856 Proton Precession Magnetometer. Magnetic susceptibilities of outcrops will be measured using the handheld SM-10 Magnetic Susceptibility Meter. Rock samples will also be collected for crushing and more precise measurement of magnetic susceptibility in the lab using the Bartington MS3 Magnetic Susceptibility Meter. Mapped magnetic anomalies will be compared with possible subsurface rock bodies using the IX2D Magnetic Interpretation Software. All necessary equipment is currently owned by the Department of Earth Science. This research is being carried out in cooperation with NorthStar Mine. Results will be reported at the meeting.

Alex Dutson, Utah Valley University Academic Affairs Introduction:

John Maynes, Utah State University Elementary Education Research on gifted education has shown that expertise development requires learning very basic skills to a high level (Bloom 1986). As a university education is meant to provide students with opportunities to develop expertise in a given field, it is imperative that universities provide learners with opportunities to learn very basic skills to a high level. However, do students receive adequate opportunities to learn the skills necessary to develop expertise? Do some students receive more opportunities than others? This study seeks to answer these questions by surveying honors and non-honors students to determine their perceptions respectively of opportunities to develop expertise in their chosen field of study. By matching each honors student with a non-honors student in the same class, the survey aims to evaluate the difference between the perceptions of honors students and non-honors students in the same class. Scager, et al indicate that honors students are more likely to develop expertise than non-honors students at a university (2011). Thus the hypothesis of this study is honors students receive more opportunities for expertise development than non-honors students.

Jonathan Hilbert, Utah Valley University Academic Affairs The Jordan River in Utah has been highly regulated for many years through intense irrigation, channelization, and managed releases from Utah Lake. As the only outlet of Utah Lake flowing north into the Great Salt Lake, it is important to the riparian ecosystem and the surrounding human population as well. The river has a long history of mixed-uses, but it is emerging as a popular recreation site for the numerous adjacent communities. Human interaction on the individual and commercial scale influences the river through development and urbanization. The physical characteristics of the river and its riparian zone can be monitored to understand how the landscape is changing over time. In this study we focus on land cover changes in the riparian zone of the upper one-third of the river flowing out of Utah Lake to what is called “the point of the mountain”. This is the portion of the river that flows in Utah County. From aerial imagery and field observations, we noted alterations in the vegetation within the riparian zone from channelization, riprap, invasive species, or removal for a variety of reasons. We use GIS and aerial imagery to evaluate the land cover change on the Jordan River in Utah County between 1992-2011. Using Anderson’s classification system of land cover, specifically Urban or Built-Up Land, Agriculture, Vegetation, and Barren Earth, we quantified the changes in vegetation within a 100 meter buffer of the river’s wetted channel. While there are areas where little change is observed, areas of greatest change occurred downstream of the outlet, where a number of new communities have been developed in the last decade. As a subset of Vegetation we mapped changed in invasive species, tamarisk and reed canary grass, along the same section of the river within the riparian zone. Urban planning and invasive species removal along the river needs to be further considered as potential future recreation and restoration efforts are advanced on the river.

Andres Chavez, Brigham Young University Education The purpose of this research is to explore the current status and condition of the public and private education k-12 in Ecuador and analyze the implications that recent policy changes made by the Ecuadorian Ministry of Education hold for the future role of K-12 schools in the country. In order to do this, I first met with the Minister of Education and received information regarding national test scores of schools in six provinces, the provinces being Guayas, Santa Elena, El Oro, Manabí, Azuay, and Pichincha. I then visited four different types of schools in each of those provinces, the types being public, municipal, fiscomisional, and private. In each of these schools, I held an interview with the principal as well as a few selected teachers, and observed the general condition of the school grounds and facilities. I found that the majority of the public schools are overpopulated, while the private schools for the poor are disappearing due to the diminishing number of students who are enrolling in their programs. I propose that the reforms that the Ministry of Education has put in place will be more effective in improving education if the number of students in each public classroom is reduced to a manageable amount. This can be achieved by the government providing subsidies and financial aid for more students to attend private schools.

Licia Kim, Utah Valley University Academic Affairs Utah is a state that was largely settled by immigrants, and among those immigrants were hundreds of Chinese people. For over 70 years, Salt Lake City was home to one of the most prominent Chinatowns in the Intermountain West. Today, Utah is home to over 10,000 Chinese people, but there is no Chinatown in Utah. If the average Utahan is asked “Whatever happened to Salt Lake’s Chinatown?” the answer will invariably be a variation of “Salt Lake had/has a Chinatown?” Yes, Salt Lake City had a Chinatown and this research project answers the question of what happened to it. By exploring existing scholarly works, oral interviews and newspaper articles from the years that Plum Alley, Salt Lake City’s Chinatown, existed, I examined the creation, heyday, decline and eventual demise of Utah’s largest Chinatown. According to my research, the Plum Alley Chinatown disappeared because of a combination of cultural/religious differences, economic pressures, racial issues, and political/legal restrictions. As the significance of China, both to Utah and the United States as a whole, increases, an opportunity is created to increase public awareness of the Chinese experience in Utah’s history. Once this history is known, Plum Alley’s location, in a familiar, near-by location, will provide students in Chinese immersion classes (and their parents) with an opportunity to form a more immediate connection with these distant people. The goal of this research is therefore twofold: 1) to create a research article suitable for publication in a scholarly journal, and 2) to create a PowerPoint presentation and/or traveling historical exhibit on Plum Alley suitable for display at schools, public libraries and other community centers (such as the new South Salt Lake Chinatown shopping center). Simple entrance and exit surveys will allow me to track the effectiveness of the presentation/exhibit to increase visitor awareness of this little known chapter in Utah history.

Brandon Dollar, Utah Valley University College Success Studies Student retention and persistence to graduation are two issues that receive significant attention and allocation of financial and human resources in higher education. A recent study (Creighton, Creighton, & Parks, 2010) stated that 26% of new freshmen do not matriculate their sophomore year. Consequently, many institutions within higher education have placed emphasis on the first-year experience (FYE). In response to the issues that lead freshmen to dropout, FYE program outcomes generally include student self-awareness (Krause & Coates, 2008), learning academic skills and strategies (Crisp & Cruz, 2010; Schrader & Brown, 2008), connecting students to campus (Zhao & Kuh, 2004; Bell, 2012) and social support (Tinto, 2009; Wilcox, Winn & Fyvie-Gauld, 2005). However, research shows that most institutions approach FYE programming with a “piecemeal approach” (Krause, Hartly, James, & McInnis, 2005) and do not take a “whole-of-institution” approach (Kift, Nelson, & Clark, 2010) where student retention and persistence are part of the fabric of the entire institution. One of the aspects of FYE programming is peer mentoring. Peer mentoring emerged within the FYE programs to facilitate these program outcomes and ultimately, student retention. In fact, an early literature review (Jacobi, 1991) on mentoring revealed four identifiable outcomes of mentoring, three of which claimed to be applicable to peer mentoring and successful fulfillment of FYE outcomes. Some peer mentoring programs emerge from student affairs (Lopez, Johnson & Black, 2010) while other programs originate from academic affairs (Colvin & Ashman, 2010). Aside from the differing origins of peer mentoring programs, research identifies six types of mentoring programs, five of which claim to be applicable to peer mentoring (Karcher, Kuperminc, Portwood, Sipe, & Taylor, 2006). However, there still appears to be no universal approach to peer mentoring in higher education. Specifically, research has yet to reveal a peer mentoring program that comprehensively synthesizes the great foundational work of Jacobi (1991) and Karcher and his colleagues (2006) and maintains the necessary theoretical alignment proposed in recent literature (Hall & Jaugietis, 2011; Crisp & Cruz, 2010) within a holistic and integrated institutional approach to student success and retention.

Buchanan Kerswell, Utah Valley University Academic Affairs Increase in population and wealth in Utah will likely result in increased fossil fuel consumption. Consequently it will lead to more environmental problems, especially air quality and health issues. It is essential to further the research and assessment of renewable energy sources. The objective of this research is to compile, analyze, map and assess energy data from the Utah Geological Survey, Utah Office of Energy Development and Utah Department of Environmental Protection. Our project will give public a clear picture of air quality and energy use coupling with population and economic growth. ArcGIS maps and statistical analysis will be made using the available database. Furthermore, detailed assessments on the development potentials of different renewable energy sources (e.g. solar, wind, geothermal) in Utah will be conducted using ArcGIS. Our preliminary data analysis on fossil fuels indicates that consumption and expenditures have grown over time with population growth. A notable fact is that when expenditures have risen rapidly, consumption tends to decline. The most recent evident periods are during the early 1980s and in the early 2000s, when oil prices were rapidly increasing. Furthermore, the data show that air quality is closely correlated with the quantity of fossil fuel consumed, especially given Utah’s special topography (the valley effect). The data on renewable energy sources have revealed that all renewable energy sources together provide less than 1% of energy need in Utah. Although the growth and development have varied during the last half century, there is a steady growth in geothermal, solar and wind energy over the last decade. Results from ArcGIS mapping will provide useful insights on zoning and assessing potential renewable energy sources in Utah. Renewable energy is the key to our economic growth and clean air in Utah. It is essential that the transition from a primarily carbon-based energy portfolio be to one that includes a greater mix of renewable sources. Further results, analyses and maps will be presented during the meeting.

Janeese Stiles, Utah Valley University Academic Affairs Previous studies have shown that high-frequency (HF) ultrasound is sensitive to cell properties such as stiffness and adhesion factors which are a function of protein expression. The goal of this project is to see if HF ultrasound is sensitive enough to detect and differentiate between the five molecular subtypes of breast cancer which are based on protein expression. Since genetic changes precede histological changes in the development of breast cancer, the ability to detect genetic changes (i.e., molecular subtypes) in breast tissue in real time and at the microscopic level will allow surgeons to remove all of the malignant and premalignant tissue during lumpectomies. HF ultrasound personalizes the treatment plan and will be used as a diagnostic technique for precise, image-guided breast cancer surgery. Four breast cancer cell lines with different molecular subtypes and a non-malignant breast cell line will be grown as monolayer cultures. At monolayer confluence, cell and nuclei morphologies of the cell cultures will be determined by phase-contrast microscopy. After microscopy, the monolayers will be ultrasonically tested using a HF ultrasonic test system with a single-element (50 MHz, 6.35-mm) ultrasonic immersion transducer. The resulting ultrasonic waveforms will be analyzed using computational models that simulate the ultrasonic scattering from cells and nuclei as a function of morphology, internal properties, and external properties. The protein expressions associated with the different subtypes will be researched to determine what effects each subtype will have on cell and tissue properties. This method will add a new dimension to pathology and permit more efficient surgical treatment of breast cancer.

Jared Crossley, Brigham Young University Education This research project was to make a film about Lloyd Alexander, one of America’s most influential authors of fantasy for young readers. Best known for his Chronicles of Prydain, including the 1969 Newbery Award winning “The High King”, Alexander won numerous awards and was translated into over 20 languages. This study includes interviews with his editors, close friends, and professionals in the children’s literature community as well as archival photographs from his life. The research actually culminated in two documentary films exploring the life and writings of Lloyd Alexander, one ten minutes long and the other an hour in length. These films already have created much interest in Alexander and his works, reaching long-time Alexander fans, as well as helping to establish some new readers of his work.

Tyson Jones, Utah Valley University Academic Affairs In 2008 the people of the United States and the world were awakened from a dream that huge financial gains can be made at the expense of huge public losses while everything will stay just and fair. Unfortunately, the 2008 economic crash wasn’t the result of just one idea in one sector, but rather a culture within economies; a culture that has not just investment bankers but everyday American and foreign citizens pursuing the same path. This path, that many American and foreign citizens have been enticed by, is a business structure that leaves an individual and their chances of success equal to the chances of failure of those that follow suit, namely Ponzi Schemes. The many people who follow Ponzi Schemes are looking for financial security along with promises of high earnings and early retirement, but are often met with greater debt than they had before simply due to the structure of these Ponzi schemes. For the most part Ponzi schemes have been made illegal in the United States; however, due to certain laws that have been established, Ponzi schemes have been operating under the guise of established businesses known as Multi-level Markets (MLMs). The laws in question are the DSHEA, which has aided MLMs on a national level, and Utah S.B. 0182, which created a loophole for MLMs to operate in large numbers on a State level. Thus a culture of legal positivist views allows the illegal and immoral business practices of MLMs to encourage a culture of harming many to reward a few. This conclusion about MLMs comes from contrasting the structure of MLMs with the moral theory of Immanuel Kant’s Categorical Imperative which requires that all moral actions be held as a universal maxim, and that people are not treated as merely means to an end. The purpose of this research is to assess whether the previous conclusion is in fact true of MLMs in regards to moral business practices through the Categorical Imperative. If after examination the conclusion is found to be true, the DSHEA and Utah S.B. 0182 both need to be revoked in order to begin a change in culture; else large amounts of U.S. dollars, as well as other currencies, will continue to fund illegal Ponzi schemes acting as legitimate businesses and an opportunity to take steps to change U.S. culture on the nature of wealth. In addition, a new culture that allowed for the 2008 financial crisis of large rewards for the few at huge public expenses will continue to grow.

Megan Curtis, Utah Valley University Academic Affairs Capitol Reef Field Station (CRFS) is located in south-central Utah within Capitol Reef National Park (CARE). Due to its arid climate and diverse geology, many plant species found within CARE have unique adaptations that are sensitive to disturbance. Cryptobiotic crusts, which play a vital role to the health of vegetation by stabilizing soils, cycling nutrients, and reducing erosion, are extremely sensitive to disturbance and can take many years to recover after being damaged by footprints. In addition, the spread of invasive species can harm native vegetation by competition for resources. Since CRFS’s founding in 2008, it has been frequented by visitors who come to learn about CARE’s natural and cultural history. Consequently, various trails and dirt roads surrounding CRFS may be a source of human disturbance and spread invasive species. Another source of disturbance is cattle that graze in this area on their route through CARE twice each summer. The objective of this study is to characterize the vegetation surrounding CRFS and determine the present level of human and domestic impact on this vegetation. Our specific questions were; (1) Is the level of human disturbance associated with plant community structure and proximity to CRFS, (2) Which communities have the highest levels of cattle/human disturbance?, (3) How does community structure vary by vegetation type? To address these questions, two 100-m transects with differing proximities to CRFS were established in each of four vegetative communities’ Pinyon-Juniper, Big Sagebrush, Riparian, and Grassland. Species frequency, cover, and disturbance (density of tracks within a quadrat) were recorded within each transect using a nested plot frequency design -four nested subplots ranging from 0.25 4m2. To account for seasonal variance, data were collected in four sampling periods throughout growing season. To characterize community abiotic factors, slope, aspect, and soil attributes were measured for each transect. To analyze the data, we ran multivariate analysis, including Non-metric Multidimensional Scaling (NMS), and Multi-response Permutation Procedure (MRPP). The two-dimensional NMS solution explained 80.1% of variability in community structure.
