Natasha Mickelson, Brigham Young University Humanities Young adult contemporary realistic fiction is a genre which attempts to portray real life. Young adult readers of these novels should be able to find themselves in the characters and relate to their backgrounds, experiences, and perspectives on life. While many young adult novels deal with controversial topics such as sexuality, drug use, physical abuse, suicide, and other difficult subjects in an attempt to be realistic, one aspect of life still largely considered a literary “taboo” is religion.Through examining studies done and looking at a sample of novels in the young adult contemporary realistic fiction genre I found that most of these books mention nothing about the religious beliefs or backgrounds of their characters. In the few novels which do bring up religion, Christian beliefs and characters are more common than minority religions. However, those novels depicting Christian characters are more likely to show them in a negative light. These novels frequently portray religious characters (especially leaders) as bigoted, fanatical, or gullible. Often the main adolescent character is trying to break free from cultish groups, and their eventual loss of faith is celebrated. Since contemporary realistic fiction attempts to portray the real world and real teenagers, I researched recent studies surveying American teenagers’ views on and involvement with religion. The results of these studies show that most teenagers identify with and willingly participate in religious groups and practices. In my research I found that this disparity between real life and realistic YA fiction exists due to the aversion of writers and publishers to possible censorship issues and alienating potential readership. However, scholars agree that both the lack of religion and the negative religious stereotypes in these novels can leave teenage readers incorrectly feeling as though their beliefs in or questions about God and religion are uncommon or wrong.

Thomas Aguila, University of Utah Humanities “A Tide Just West” is a book arts project that conceptually adopts the theories of Hélène Cixous– and to an extent Julia Kristeva and Luce Irigaray– and concerns itself with investigating narratological schemas, as the book experimentally utilizes photographic imagery (alongside the text) to constitute a story of écriture féminine. Ecriture féminine, translated from French as “woman’s writing,” is a type of writing characterized by its tendency to subvert the narrative conventions and the pragmatism within books, poetry, language, and the genres in between. Hélène Cixous used this conceptual term in her 1975 essay, “The Laugh of Medusa,” and considered the difficulty of definitively putting into words such a category: “It is impossible to define a feminine practice of writing, and that impossibility will remain, for this practice can never be theorized, enclosed, coded.” In this project, écriture féminine takes form– and subverts form– through the book’s incorporation of photographic images. The narrative’s images act as areas that are not reliant on words but visual experiences that contradict, unify, and break apart the text alongside it. Such visual components allow new narratives to form. Instead of illustrations, the visual images act as indefinite, experiential moments for the reader to expand upon (to pass through), as the reader’s literal relationship to the characters, scenarios, and overall thematics of the book turns more toward conflicting, potent, and vague contradictions. The images fracture and destabilize the logocentrism of the book, destabilizing that expectation and faith upon the written word; they act as an in-definitude to the text, the narrative, the body, and the metaphors between the three.

Amanda Salgado, Weber State University Humanities In 1983, Rigoberta Menchu, the first indigenous Mayan-Quiche Nobel Peace Prize recipient, shared the terror and the abuse that she and millions of other indigenous people in Guatemala were experiencing during the country’s 36-year Internal Armed Conflict. In her book Me llamo Rigoberta Menchu y así me nació la conciencia, she discusses how the indigenous population was frequently viewed and treated as inferior by the Ladinos (those of mixed indigenous and European heritage), and was therefore subjected to a great deal of discrimination, which was reflective of the legacy of the country’s colonial past. The purpose of this research was to examine within a Postcolonial framework, if postcolonial structures were still in force in Guatemala, and if and how they continued to affect the indigenous population, particularly Mayan women living in rural areas. Methodology included analysis of newspaper articles, journals and documents, as well as a two-week field experience, talking to Mayan women. The result shows that while the political situation of Guatemala has improved since the time of the publication of Menchu’s book, many of the conditions and practices that promote discrimination against the indigenous population have continued and are still visible today, reflective of a Postcolonial society that values European descendants more than their neighbors. For instance, the educational system now takes into account indigenous languages, and Mayan spirituality is not persecuted, a first since the Spanish Conquest. Nevertheless, indigenous women continue to experience a triple discrimination because based on their sex, social status, and ethnicity. The goal of this research is to promote greater awareness of these issues.

Matthew Dye, Snow College Humanities Many Native American reservations in the United States are increasingly relying on casinos and other forms of gambling to bolster local economies. However, since the state of Utah does not allow gambling on tribal lands, Native Americans in Utah must rely on other activities to bring tourism to their communities. Many resources that are available to tribes across Utah, including pow wows and other cultural events, have become central economic activities and means for increasing tourism to tribal lands. These cultural events serve two purposes, as they serve as a means of cultural education to the larger public, in addition to providing a mechanism for increasing tourism. For this project, I will focus on how the different Native American tribes in Utah use their own unique cultures to attract tourism, and its accompanying economic benefits, to their communities.

Miranda Roland, Southern Utah University Humanities Voluntourism (volunteer tourism) is the action of using personal vacation time to assist in volunteer service usually in foreign countries. Voluntourism has recently received negative connotation as research has deemed them “non-beneficial” or even “harmful” due to the short duration spent and overall adverse effect caused unintentionally by the project. This research was conducted to determine what participants of the temporary medical clinics hosted by the Global Medical Training program really think of the provided service. This information can deem if the alternative breaks taken by pre-medical and medical volunteers are beneficial to the areas they serve and if future breaks should be considered, if not strongly encouraged. The surveys were completed verbally to the patient with the aid of a Spanish translator. Surveys contained questions that addressed the influence of how they receive medical attention due to these clinics and satisfaction of attention received during the clinic. All of the surveys (100%) signified that these Global Medical Training clinics do influence how they receive medical care with additional comments of “beneficial to the low class economy”, “traveling to us is very helpful”, and “appreciate the advice given”. 98.08% signified that they are satisfied with the medical attention received through the clinics. As demonstrated through these results many communities are satisfied with the service provided and they wish to see more clinics of this set-up as it relieves the cost financially and time-wise of traveling to the nearby medical center. Upon conclusion, the trips taken by pre-medical and medical students through the Global Medical Training program are deemed beneficial to both the volunteers and the recipients of their service. These trips should not be demoted by the negative connotation of voluntourism but instead should be strongly encouraged if a volunteer desires.

Rachel Sharich, Dixie State University Humanities Non-traditional students face innumerable challenges during the course of their studies but can find a successful balance if they have the proper tools and a determined mindset. Going back to school after a decade or more is a daunting task when considering work and bills, kids and dinner, laundry and car repairs. In 2007, I attempted to describe my city-girlturned- agrarian-survivalist efforts in self-reliance after gutting my extra rooster and cooking him for dinner. Then, my life changed. I became a full-time college student and after a few semesters, I realized that my knowledge of grammar and punctuation had grown significantly since my rooster-killing musings. I re- learned comma rules, proper use of semi-colons, and the difference between a dash and a hyphen. Although storytelling is a personal strong suit, I now see many flagrant errors in my past writing. Comma splices are scattered throughout email, journal entries, and even handwritten notes. I overburdened any sense of idiosyncratic expression with abundant stylistic fragments. I attach my success or failure as a human being to the letters on my report card; I have always been an ‘A’ student. College cannot be the top priority for most non-traditional students. I strive for some sense of lop-sided equilibrium each day and encourage other potential students to realize their own dream of earning a college degree, no matter their circumstances. I enjoy assisting other students in correcting their own writing errors. I am content with any passing grade because I am seeing my work, and my life, change for the better.

Jordan Kerns, Dixie State University Humanities In my creative compilation, I explore four different classifications of the word blood in four flash non-fiction pieces. I utilize the writing technique of compression, so none of my stories exceed 400 words. Flash pieces give information to the reader through the techniques of inference and understatement. Throughout my stories, I show readers my relationships with other people, my thoughts about myself, and my opinions about certain possessions through the use of flash methods and with an underlying theme of blood. The first story, “Cremation,” illustrates my relationship with my brother through a cryptic conversation we had about death—its tie to the theme being our blood relation. The next piece, “Blood Lines,” describes a pair of sweatpants I stole from my father with subtle clues that hint at the bad blood left between him and my mother and my mother and me. The third flash, “Blood and Frosting,” is a second-person narrative about the process the narrator takes to make red velvet cupcakes for her friends and family. The last work, “Syrup and Sky,” is another descriptive paragraph about a picture I drew in high school of a poorly-drawn wolverine covered in the blood of his kill. I aim to connect with my readers through these simple moments of life, make them feel either happy or sad or anything in-between, and make them see the beauty and complexity in mundane things.

Conor Hilton, Brigham Young University Humanities The narrator of Washington Square strongly colors the account of events that we receive. However, this information is tainted by the narrator’s treacherous behavior, seeming to be very polite, but hiding a heavy dose of irony and distaste behind the polite exterior. It is difficult to fully understand and interpret the events of the novel given the narrator’s heavy involvement in relaying the events of Catherine and Dr. Sloper’s interactions. The text must be interrogated, questioning the motives of the narrator and the reliability of the narrative that he presents. If the narrator is a friend to Catherine, then he likely is undermining Dr. Sloper. Yet, if the narrator is a friend of Dr. Sloper’s, as his intimate knowledge of the Doctor’s past and perspective suggests, then it seems unlikely that he is also a friend of Catherine’s. Perhaps the narrator is unsympathetic towards all of the characters, seeking to undermine their actions and words regardless of who they are or what they are striving to do. The narrator hides his biting asides behind a mask of the most formal politeness, but upon reading between the lines the narrator’s kindness and friendship for each of the characters is called into question. Understanding that the narrator is no friend to the characters in the story he is telling, the reader must question all interpretive comments made regarding the events of the novel. Stripping away the bias of the narrator is also essential to understanding the true nature of the characters of James’ novel, primarily Catherine and Dr. Sloper.

Marcos Camargo, Dixie State University Humanities Since Europeans began to settle in the Western Hemisphere, Native-Americans faced a prolonged and painful voyage of dispossession. Traditionally historians look at the cultural, demographic, and political losses faced by Native Americans, rarely addressing the geographic aspect of the loss of natural resources. In the early period of the Cold War, uranium because a very precious commodity for both Americans and Soviets in the production of nuclear weapons. Since the best sources for uranium in North America were located primarily on Navajo lands in Utah, Arizona, and Colorado, the US Federal Government was forced to form a new relationship with Navajo leaders. These political advances undercut egalitarian traditions in Navajo governance, facilitating a new hierarchical structure where individual tribal members could exploit the American demand for uranium for their own personal profit. Through institutions like the Bureau of Indian Affairs, the US government did their best to hand-pick tribal officials who would acquiesce to their intensified desire for Navajo resources. This paper will investigate tribal reactions to the Navajo leadership’s complicity with US uranium policy and corporate profiteering. Only when the tribal government acted in the interests of the tribal community as a whole, through regulations that protected the Navajo homeland, were the wrongs perpetrated by outside forces able to be mended.

Michael Jurgensmeier, Dixie State University Humanities The voyage of slaves from Africa to the Americas is a part of Atlantic World history that is infamous for its brutal treatment of human cargo. The recorded history of men, women and children placed in cargo ships, chained together, lying in the same spot, often for months at a time without seeing the light of day, has been met with a mix of horror and shock. The specific details of the slave trade have been well recorded and the role of the human cargo has been emphasized in the majority of records that fill history books. What about the role of the slave trader? When a person takes into account all the added stress and special-needs of carrying a ship filled with human cargo, one can’t help but ask, from an economic perspective, was it worth it? Was it exceptionally profitable? In answering that question perhaps a light will be shed on the motivation of one of history’s iniquitous periods. This paper will give a few, short examples of what slave traders had to consider and the types of problems they may have had to overcome in order to be successful.

Missy Jessop, Dixie State University Humanities I moved from the suburbs of Salt Lake City to southern Utah just about four years ago, and the land continues to evoke fear and reverence in me as it did when I first arrived. Moreover, the desert has worked itself into my writing. Not only do my conflicted feelings about this place surface in both my prose and my poetry, but images of the landscape, as well as its animals and climate, appear over and over. The desert, I would argue, functions as an objective correlative, directly complementing and indirectly commenting upon the actions, images, people and scenarios that comprise this work. As such, I have begun to agree with Wordsworth’s observation that “a large portion of every good poem…must necessarily, except with reference to the metre, in no respect differ from that of good prose.” In this presentation, I plan to share “flash” works of prose and poetry that problematize the alleged divisions between different literary forms. In support of my findings, I will draw upon the ideas of such writers and critics as David Lee, Sarah Kay, and W.B. Yeats. It is my hope that the audience will be reminded of the connection between nature, landscape, and artistic expression, and how this connection can be tangibly observed by individuals in their own creative lives.

Samantha Falde, University of Utah Humanities The purpose of this paper is to closely examine the legacy of the policies and actions taken by the Soviet Union during the Cold War in order to determine its contributions to current levels of small arms and light weapons (SALW) proliferation around the globe. This examination confirms as reality the perception of the Soviet Union as the primary propagator of indiscriminate small arms proliferation in the post-Cold War era. As such, the Soviet Union was a chief contributor to the current situation of global insecurity perpetuated by the creation of extensively armed and violent societies known commonly as Kalashnikov Cultures. In examining the impact of Soviet policies on SALW proliferation, this paper utilizes the concept of the ‘‘Non-State Threshold’’ at which, when intact, small arms and light weapons are effectively segregated between legitimate state and illegitimate non-state actors, and when breached, indiscriminate spread occurs. The Non- State Threshold will be applied to the years during and immediately following the Cold War to determine under which conditions indiscriminate SALW proliferation occurred, and to facilitate a clearer understanding of how Soviet policies and actions allowed for the permeation of the Threshold by increasing the availability, ease of acquisition, and appeal of SALW to non-state actors and illegitimate groups. This paper demonstrates how the legacy of Soviet policies has facilitated the creation of dangerously armed, rogue societies, supporting the claim that it is the actions of the Soviet Union specifically that have disproportionately contributed to the creation of Kalashnikov Cultures.

Wendy Stabler, Dixie State University Humanities Injuries to the brain, scalp, and skull are considered to be head injuries. In recent years, Traumatic Brain Injury (TBI) has become the “silent epidemic,” leaving survivors to fend for themselves in most aspect of their lives. A massive lack of knowledge and understanding with regard to TBI besets the community and Dixie State University (DSU) in particular. As a result TBI students do not receive the services, resources, and empathy they need for scholastic success. In order to ensure that TBI students can thrive on campus, DSU’s Disability Resource Center, administrators, and instructors need to implement new programs that support TBI students and educate the general campus population about the effects and learning styles associated with TBI. Some of these new programs (i.e., better accommodations, a TBI support group, DSU training on TBI) may be extensive and difficult to incorporate at the University, but they are critical for TBI students. Drawing upon published data and statements provided by TBI students and educators, with this paper, an exercise in rhetoric, I will demonstrate how more knowledge and information on this campus will empower instructors as well as TBI students, potentially yielding higher graduation rates for TBI students. Once the recommendations are implemented, DSU will in turn be a leading university in TBI student support. The hope is that these findings and arguments can be used to help TBI student communities in other higher-education settings.

Aaron E. Palmer, Dixie State University Humanities While traditional storytelling revolves around the story and setting, video game mechanics include all game rules and options for interaction in and with a game. Due to this, a pair of critical questions arises: how do video game mechanics— such as functions on a controller—influence the production of meaning within video game narratives, and have these mechanics progressed or expanded upon the ways stories can be told? I argue that mechanical elements have expanded, enriched, and altered storytelling. Using N. Katherine Hayles’ Writing Machines as a guide, I compare conventional literary artifacts, such as novels, to video games vis-à-vis Hayles’ theories regarding “Literary texts … [as having] bodies, an actuality necessitating that their materialities and meanings are deeply interwoven into each other.” My research reasons that playing narrative-driven games is creative rather than solely reactive. The following video games are included in my research: Brothers: A Tale of Two Sons, The Elder Scrolls: Skyrim, and The Legend of Zelda: Majora’s Mask. For millennia, humans have painted caves, etched steles, and carved hieroglyphs onto walls in order to communicate important stories. The evolution of media from stone to parchment to newer media such as computers exposes the role that gaming mechanics play in contemporary storytelling.

Matthew Halverson, University of Utah Humanities Adults learning second languages typically exhibit a great deal of difficulty discriminating the sounds of the new language. For example, the English R and L sounds (as in ‘lead’ vs. ‘read’) are difficult for native speakers of Japanese to discriminate because there is no such sound contrast in Japanese. Despite these difficulties, some research indicates that there are cognitive benefits of being bilingual. For example, Bialystock et al. (2003) found that bilingual children performed more accurately on tasks testing phonological awareness (a measure of sound-related skills) in English when compared to monolingual English speakers. Antoniou, Best, and Tyler (2013) found that Greek-English bilinguals were better at discriminating contrastive word-initial consonants in the language Ma’di than English monolinguals—but that they performed worse than Greek monolinguals. We thus see that the apparent bilingual advantage may be confounded with the particular language backgrounds of participants in these studies. The present study attempts to tease apart the contributions of language background and bilingualism. Spanish-English bilinguals were compared to English monolinguals in their ability to discriminate Thai sounds. The predictions were that if Spanish-English bilinguals performed better than English monolinguals, it would indicate that bilingualism was responsible for the advantage. On the other hand, if there was not a significant difference or the Spanish-English bilinguals performed worse than English monolinguals, the results could be attributed to language background. We found that there was not a significant difference between how the Spanish- English bilinguals performed compared to English speakers. We note that the study, however, is limited due to a lack of a Spanish monolingual group, thus we were unable account for a possible effect of language background.

Ashley Smith, Brigham Young University Humanities The author argues that attitudes towards cross-caste marriage in Visakhapatnam, India are changing due to women who have attained a degree in higher education. Attitudes towards cross-caste marriage in India have always brought about turmoil for families whose children decided to marry someone outside of their caste. While cross-caste marriages are now legally allowed in India, it is still so socially taboo that even those that do participate in cross-caste marriage do not like to tell others that they are part of a cross- caste marriage. But times are continuing to change. The author’s research in Visakhapatnam, India concerning cross-caste marriages, and marriages in general, have brought to light data that may show that attitudes towards cross-caste marriage are changing in the light of higher education. Those interviewed by the author who were willing to talk about their own cross-caste marriage, or their son’s or daughter’s cross-caste marriage, have stated that or made mention to the fact that those who were well-educated were more willing to participate in cross-caste marriage as well as speak of being in a cross-caste marriage. It’s how people speak of it though that makes the author’s research interesting. They speak of their cross- caste marriage through education. It was either their mothers or themselves that mentioned that they have had higher education, usually at a university that the attitudes they grew up with about cross-caste marriage are softened.

Andy Mickelson, Brigham Young University Humanities The infancy narrative in the Gospel of Luke is one of the most popular passages of Christian scripture: the story of Jesus’ birth has been recited and depicted in Christmas celebrations for centuries. Yet modern readers are far removed in time, language, and culture from the first-century world in which Luke was composed. Because of this distance, our traditional understanding of this text may differ from what Luke intended to convey. One particular misunderstanding of the text centers on an ambiguous Greek term used in Luke 2:7. Most English translations of this verse state that Mary, after delivering Jesus, “laid him in a manger, because there was no room for them in the inn.” However, the term translated as “inn” in this passage—κατάλυμα—had a wide variety of meanings in Hellenistic Greek. Even within Luke itself the term is translated differently: the “upper room” in which Jesus shares his last meal with his disciples is, in Greek, a κατάλυμα (Luke 22:11). Properly understanding κατάλυμα profoundly impacts how we read Luke’s infancy narrative: were Mary and Joseph turned away from a crowded inn on the eve of her delivery? Or does a nuanced translation of κατάλυμα change the circumstances of Jesus’ birth?This paper philologically examines how κατάλυμα is used by other Hellenistic Greek authors: Xenophon, Polybius, Diodorus Siculus, and others. Their writings created the literary milieu in which the Gospel of Luke was composed; their use of this term may have influenced Luke as he crafted his account. Based on this philological context, κατάλυμα here most likely means “guest room,” and infers that Joseph and Mary were staying with another family (possibly relatives) in Bethlehem. This reading, though nontraditional, brings us closer to approaching the text as Luke’s original audience would have understood it.

Latrisa Garcia, Dixie State University Humanities Statistics show that in 2013, the US population was 313.9 million people, while the number of active cell phone subscriptions was 345.2 million, which translates to 110% of the US population having active cell phones. As more people connect to the world through cell phones they become less aware of the physical world which surrounds them, known as Inattentional Blindness. This paper asks the question: Does the increased use of cell phones impair college students’ perceptions about the actual amounts of crime that occurs on campus, and if so are students under or over estimating the amounts of crime? It is hypothesized that the majority of students will under estimate the amount of crime that occurs on a college campus because of their reduced awareness of the real world. This study uses a convenience sample acquired through a web based survey conducted on a college campus of approximately 10,000 students in the southwest region of the United States. Study results will be finalized in the coming weeks. Early results suggest that cell phone use and inattentional blindness may not be as prevalent on campus as originally hypothesized.

Savannè Bohnet, University of Utah Humanities The University of Utah attracts students from all over the world. Many international students serve as graduate teaching assistants, and in doing so, contribute to the teaching mission of the University. International Teaching Assistants (ITAs) experience a number of challenges associated with their teaching duties, most noticeably communication difficulties that are typically attributed to their non-native accents. In recent studies on accent adaptation we have seen that native English speakers are in fact able to quickly and accurately adapt to unfamiliar or new accents; however, most of these studies have been conducted in highly- controlled laboratory contexts. In the present work, we have examined the ability of actual University of Utah undergraduate students to adapt to the speech of actual ITAs, with the goal of understanding how to harness this accent adaptation ability to improve communication and learning in the classroom. As a starting point in achieving this long-term goal, we are investigating how individual students vary with respect to this adaptation ability. We conducted an experiment where native English-speaking University of Utah students were asked to listen to recordings of ITAs producing running speech during an adaptation phase. Following the adaptation phase, these students were asked to perform a transcription task with individual words produced by the same ITAs. More accurate performance on the transcription task is interpreted as greater adaptation to the ITAs’ speech. We found not only that different ITAs exhibited different levels of intelligibility to students, but also that individual students varied widely in their adaptation ability, which means that the intelligibility of non-native speech depends on characteristics of the listener.

Kelsey Jetter, Dixie State University Humanities Thousands of advertising messages that are created by the media bombard the general public on a daily basis. An aspect of media that is seldom recognized is how sexuality is represented. The fight for sexual equality has been progressing over the last few years, the LGBTQ (Lesbian, Gay, Bisexual, Trans*, and Queer) community has been fighting for equality in marriage, housing, and employment—successfully utilizing many forms of media such as news networking and social media. Though successful, the community’s fight fails to recognize bisexuality as its own form of sexuality. Bisexuality is misinterpreted, misunderstood, and discriminated against in heteronormative and homosexual media—bisexuality’s representation is skewed and perpetrates the myths that are assumed about bisexuality. Some of the myths including that bisexual people are confused, unnatural, and promiscuous. Through the analysis of how bisexuality is both negatively and positively reflected in media such as the music by Frank Ocean, the television show Doctor Who, and the political figure Kyrsten Sinema, this piece finds how the media represents bisexuality, people who identify as bisexual, and how it is reported to the public.

Keiran Presland, Dixie State University Humanities A nonfiction narrative essay, “Blood and Ink” chronicles a moment during which I experienced a rite of passage. I had a quill pen wrought on my forearm to remind me every day that the act of writing is an essential and permanent component of my life and my identity. This essay employs structural and thematic principles articulated by theorists like Vivian Gornick and Dinty W. Moore. In addition, it reveals the stylistic influence of the essayists E. B. White and Annie Dillard. With “Blood and Ink,” in short, I exploit my past and utilize my intellectual training to produce a work that at once is deeply personal and technically sound.

Jacob Oscarson, Dixie State University Humanities In 1971 the New York Times printed sections of a classified Department of Defense report known at the Pentagon Papers. The papers were a detailed history of the Vietnam War from its very beginning in the 1940s when Ho Chi Minh and the Vietminh were officially considered US Allies against Japan. One phenomenon that the papers reveal quite clearly is that while President Roosevelt was dedicated to a policy of support for national liberation movements, that others within his administration did not hold the same view. This is clearly portrayed in the discrepancy between internal documents of the US Secretary of State in August, 1940 that are in clear contradiction to the Atlantic Charter that President Roosevelt promoted one year later. Throughout the history of the Vietnam War, such discrepancies between internal views and public statements were quite common. In the final days of President Johnson’s administration, he had Daniel Ellsberg collect a detailed report on all aspects of the conflict in order to shape a better policy. When the Nixon administration ignored Ellsberg’s expertise, he leaked partial elements of the documents to the New York Times. In the last decade, the US Government has now released the full details of the report for the general public. This paper will discuss the beginnings of the war during the Roosevelt and Truman administrations in regards to new information provided in the complete Pentagon Papers report.

Daniel Cox, Dixie State University Humanities Community correctional professionals stand between offenders and their potential relapse into criminal behavior, i.e., recidivism. These officers are expected to monitor conduct and use evidence-based practices for rehabilitation. However, this important dual-role is too often distorted. Researchers have noted that training for officers about the use of evidence- based practices filters through officers’ attributions (their values and professional orientation), thereby impeding implementation of these practices (Whetzel et al. 2011). In this presentation, I argue that training of this sort often fails apparently because its delivery does not address officers’ attributions, especially regarding stereotypes of psychology and organizational support. I plan to suggest that recidivism, as well, will drop when training accounts for how and to what extent attribution biases interact with efforts to implement evidence-based practices. These preliminary findings are drawn from a study I am leading that assesses 50 officers throughout the State of Utah, utilizing surveys provided by researchers Mario Paparozzi (University of North Carolina– Pembroke) and Jennifer Skeem (University of California– Berkeley), about their attributions prior to and after training to measure for positive change in using evidence-based practices. The study also evaluates officers’ use of evidence-based practices during interactions with offenders with evaluation tools provided by researchers Peter Raynor (Swansea University) and Faye Taxman (George Mason University). The intent of the study, ultimately, is to determine if and to what extent attribution-based training for evidence-based practices will cause positive organizational change, the outcome of which is likely not only to influence the manner in which correctional professionals are trained but also the manner in which their training manuals are written.

Shireen Partovi, Utah Valley University Physical Sciences The normal flora of microbiota that resides in our gastrointestinal tract acts as a community and provides a number of functions such as assisting with the breakdown of waste, protecting our tissues and organs from invading species, and playing a role in the immune response. These microorganisms may also play a role in altering our brain chemistry and changing our psychology and behavior. This mechanism is considered to be due to their ability to produce neurochemicals that mimic those produced by our own bodies. Therefore, it is possible that antibiotics may have a detrimental effect on our gut flora, thereby inducing a host of undesired side effects. These described side effects may include changes in normal psychological behavior, such as the presentation of anxiety or depression. This hypothesis is increasingly relevant as antibiotic resistance is rising due to poor education regarding bacterial infections and as the appeasement of insistent patients continues. This research aims to illustrate the harm that over-medicating may have on our behavior as a result of afflicted gut microbiota. This research will use peer reviewed journal articles that include studies and experiments to determine the influence of gut microbiota on brain chemistry and therefore psychology and behavior. Specifically, the exact implications of consistent antibiotic use and the impact on gut microbiota will be examined and a correlation will be presented. Therefore, the purpose of this research is to illustrate this problem in regards to the healthcare industry and the over-medication of patient.

Ashleigh Wilson, Utah Valley University Physical Sciences At many institutions, the algebra-based introductory physics courses are populated with students specializing in biological fields such as preparation for medical or dental schools. While the main focus on the course is to provide the students with a solid conceptual understanding and solving problem skills in physics, the students often see little application towards their fields. This is particularly true in the traditional introductory physics laboratory experiments and demonstrations, which often focus on basic applications and offer no direct relation towards the medical fields. As part of a summer research project, we explored the possibility of developing a low-cost NIR imaging system, which could be used in demonstrations, laboratory exercises, as well as student research projects. The use of infrared imaging in medical physics is an emerging technology with promising prospects, including thermography, biometry, and phlebotomy. For example, when using near infrared (NIR) light (700-1100 nm), vein imaging and mapping is possible. Due to the deoxidized nature of hemoglobin in veins, it exhibits strong absorption at a certain wavelength (~730 nm). The surrounding tissue and arteries, however, allow the radiation to pass through. Utilizing an array of different NIR wavelengths and a modified web camera with a combined cost of $150, we successfully created a low-cost NIR imaging system capable of mapping out veins. This poster will present the instrument setup as well as show the preliminary results. Further potential use of this system will also be presented.

Ashley Ostraff, Utah Valley University Physical Sciences Utah Lake has a long history of being impacted by anthropogenic activities like, mining, agriculture, and surrounding industry. All of these activities have contributed to the runoff that feeds the lake, increasing the likelihood that this area contains high levels of trace metals, nitrogen, andphosphorus. Utah Lake contains two subspecies of phragmites, a wetland reed, one native (P. americanus) and one non-native (P. australis). P. australis is replacing the native species at an alarming rate. P. australis is known to have a deeper root system than the native subspecies, because of this we suspect that this allow access to a less competitive soil level giving this subspecies greater opportunity for nutrient and trace metal uptake. By comparing the root zone soils of both subspecies we hope to gather results that support this hypothesis. Examination of the roots will also showthe potential influence the soil conditions have on their growth and development. This study will compare nutrient and trace metal uptake of each subspecies to determine impact. Other factors that will be assessed include plant physiology, carbon to nitrogen ratio (C:N), bioconcentration factor (BCF) and total trace metal content in tissues of both species. Samples of P. americanus and P. australis will be collected at 9 locations in Utah Lake. Soil samples at the root zone of each plant will also be evaluated. Each sampl e will be digested in the Microwave Accelerated Reaction System and analyzed in the Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) for C, N, P, K, Ag, Al, As, Ca, Cd, Cr, Cu, Fe, Hg, K, Mn, Na, Ni, P, Pb, Ti, and Zn. Results from this study will contribute valuable data to future efforts being used to preserve the biodiversity of the plants and animals that live in and around Utah Lake. The end goal of this student project is to be submitted to peer-reviewed scientific journals for publication and to be presented at academic and scientific conferences.

Kimberly Lowder, Weber State University Physical Sciences The herbicide Roundup and its active ingredient, Glyphosate, are widely used for weed control. These chemicals end up into streams and lakes, including the Great Salt Lake where it adversely affects wildlife. The goals of this project are a) to assess the mortality rate of Artemia larvae exposed to various concentrations of Roundup concentrate after a short exposure (48h) or a long-chronic exposure (7 days), b) to assess the effect of chronic on survival, maturation and fertility and c) to quantify the stress response of the shrimp on the heat-shock proteins 90 and 70. Materials and Methods: For the acute exposure, Artemia larval mortality was calculated in larvae exposed to Roundup concentrations ranging from 10-3 to 10-10 ml/l of Roundup concentrate for 48 h. For the chronic exposure, larvae were raised in the above Roundup concentrations. Mortality, maturation and fertility rates were calculated. The response to stress was assessed by quantifying the up-regulation of stress proteins hsp90 and 70 using western blots. Results: All larvae were killed after exposure at 10-4 g/l or greater of Roundup concentrate. Most larvae survived at Roundup concentrations of 10-6 ml/l or less. While chronic exposure to lower Roundup concentrations did not seem to affect survival or maturation rate, it did affect larval development. Larvae developing in 10-7 ml/l or more Roundup had about a 20% risk of not hatching or dying shortly after hatching. Hsp70 western blots showed an upregulation of this heat-shock protein at 10-5 ml/l or higher Roundup concentrations.

David Sutterfield, Utah Valley University Physical Sciences When sulfide-bearing rocks are exposed to oxidizing conditions, they become destabilized, leaving behind a framework of leached, altered, and replaced host rock called a gossan. Many of these gossans form by the oxidation of ore minerals and have been known since antiquity to be associated with ore deposits. However, the extent and quality of ore mineralization beneath a given gossan cannot readily be determined through surface sampling of minerals. Work conducted by mineral exploration professionals (in Africa, Australia, India, and the Middle East) has indicated that geomagnetic and geoelectric surveys of a gossan can be useful for constraining the shape, size, and economic potential of an associated ore deposit. Although gossans are found in Utah, there have been no published studies of these rock units either in terms of their economic potential or geophysical signature. The objective of this study was to carry out geomagnetic and geoelectric surveys to determine the geophysical signature of gossans exposed about 10 miles northwest of Vernal, Utah, on the southeastern margin of the Uinta Mountains, for the purpose of estimating the grade and depth of possible sulfide mineralization. The gossans overlie a heavily brecciated wedge of Mississippian Madison Limestone and are structurally bounded by the South Flank Fault, which forms the boundary between the Permian Weber Sandstone to the south and the Neoproterozoic Uinta Mountain Group metaquartzites to the north. Geoelectric measurements with an Iris Instruments Syscal Junior Resistivity System and inversion of a portion of the resistivity and chargeability data with the Interpex IX1D Sounding Inversion software shows a resistivity low (~200 Ω·m) and a chargeability high (~7 ms) below 23 m depth. Measurements of total magnetic field using a Geometrics G-856 Proton Precession Magnetometer were modeled with Interpex IX2D-GM Magnetic Interpretation Software and constrained with magnetic susceptibilities of exposed rocks measured in the field using a SM-20 Magnetic Susceptibility Meter. Models based upon a portion of the data show anomalies of amplitude about 100 nT and wavelength about 50 m, suggesting isolated bodies of elevated magnetic susceptibility (~0.08 SI units) with upper surfaces 20-30 m below the surface. Since, based upon the topography, the depth to the water table is also 20-30 m, the geophysical measurements are consistent with the presence of reduced sulfide bodies below this depth. Further work will include interpretation of remaining data and possible drilling for improved calibration of geophysical models.

Kevin Jackman, Utah Valley University Physical Sciences Phragmites australis is a non-native subspecies of wetland reed that was introduced to Utah Lake from Europe during early exploratory settlements and is now outcompeting native flora in the lake’s wetland ecosystem. Utah Lake is a repository for toxic heavy metals from diverse mining operations and industrial operations proximal to the water. International studies have shown Phragmites to have strong potential as a phytoremediator and a reliable biomonitoring species of polluted water and soil, yet no work in this regard has ever been performed in the state of Utah or on Utah Lake. It is by measuring the concentrations of arsenic, lead, and 12 other trace metals within the root and rhizome system of these plants that a measurement of the contamination of the lake can be made, and to determine a quantitative concentration and severity of contamination with regards to public health and safety. If these trace metals are present in excess in the lake and its soils, toxic, and harmful conditions are present and are an issue of health to the natural ecosystem of the lake, as well as the citizens recreating and working throughout the lake on a regular basis. Determination of atomic content evaluation will be performed by the Induced Coupled Plasma Optical Emission Spectrometer. Future work can then be proposed to remediate the lake, in an effort to improve the human and environmental condition of the area. This project has the interest of the Utah Department of Environmental Quality and relationships have been established for current and future cooperation. The aim of this project is to be published and presented on a peer-reviewed level in scientific journals and at conferences.

Brandon Davies, Utah Valley University Physical Sciences Epithelial ovarian carcinoma (EOC) is the sixth most common cancer in US women. The long-term cure rates are low due to the lack of reliable biomarkers for early disease detection, resulting in advanced stage diagnosis. Approximately 75%-80% of ovarian cancers are diagnosed at stages IIIV with a 10% 5-year survival rate despite aggressive treatments. Claudin proteins are being studied as possible biomarkers as they are aberrantly overexpressed in EOC tumors. The Claudin family of proteins are a main component of tight junctions in the upper region of epithelial cells that act as gateways for the exchange of water and solutes while also helping determine the cell’s polarity and function. Changes in these proteins cause changes in phenotype and function of normal epithelial cells, such as proliferation control, trans-epithelial resistance, polarity, and solute transport. Claudin-16 is often aberrantly expressed in breast and ovarian cancer, while Claudins 3- and 4 are highly overexpressed in EOC. The location of these proteins is also correlated with oncogenic transformations and cell proliferation. Determining the specific characteristics of these Claudin proteins can prove to be of incredible benefit in cancer treatments. As these proteins are targeted during these therapies, these tight junctions may then send normal signals, which in turn can regulate the cell normally. The C-termini of the Claudins, which are cytoplasmically located, contain a known PDZ-binding motif and may interact with other junction proteins or with proteins involved in interesting signaling pathways. To identify these interacting proteins, we will use the Expresso T7 Cloning System (Lucigen Corp., Middleton, WI) to purify the Claudin-16, -3, and -4 C-terminal tails to use in pull-down assays. This process includes using affinity tags to capture the Claudin tails by FPLC, which can then be analyzed by SDS-PAGE and, ultimately, the corresponding genes cloned and sequenced. This study can potentially provide crucial information in relation to how members of the Claudin family interact with other proteins that are commonly found in tissues that are misregulated in cancer. With this data treatments can be improved to increase the responsiveness of ovarian cancer patients.

Robyn Omer, Utah Valley University Physical Sciences Removal of all malignant tissue during lumpectomy is critical for preventing local recurrence of the breast cancer. Failure to remove all cancer results in 20-40% of lumpectomy patients returning for additional surgery. At Utah Valley University, a method is being developed to detect cancer during the initial surgery to ensure all of the cancer has been removed. Peak density, which is the number of peaks and valleys in a specified spectral range of a high-frequency (HF) ultrasound signal, correlates to breast pathology in lumpectomy specimens. The objective of this study was to determine if the histograms of peak density versus the number of measurements provide information on corresponding breast tissue pathology. High-frequency ultrasonic data were obtained from a blind study of surgical specimens obtained from 73 lumpectomy patients at the Huntsman Cancer Institute in Salt Lake City, Utah, and South Jordan, Utah. The data were normalized to remove bias between patients. The ultrasonic signals were converted to spectra using a Fourier transform. Peak densities were calculated from the spectra by counting the number of peaks and valleys in the 20-80 MHz range. This was achieved by counting where the slopes of the spectra (their derivatives) crossed zero. A histogram was created by assigning each peak density value to a bin, and then counting the number of measurements that fell within that bin. The histogram of the peak densities produced an asymmetric Gaussian-type distribution with a range of peak density values from 0 to 27 and a mode of 5. Using threshold values determined from a pilot study for differentiating pathology with peak density, it was determined that the peak of the distribution (5-6) corresponded to normal tissue pathology, the shoulders of the distribution (0-4 and 7-10) corresponded to abnormal pathologies, and the tail of the distribution (11-27) corresponded to malignant tissue types. These correlations matched the types of specimens tested, specifically tumors, margins, and lymph nodes. The correlations also provide a measure of the success of removing malignant tissue and achieving negative margins during lumpectomy procedures. Using histograms to analyze the data not only provides a new approach for differentiating tissue pathology, but also provides a statistical measure of the success of lumpectomy procedures performed by a specific surgeon or at a specific institution.

Zachary Coffman, Utah Valley University Physical Sciences Breast density describes the proportion of connective tissue versus the fat tissue in the breast. Studies have shown that women with higher breast density are four to five times more likely to develop breast cancer than women with lower breast densities, (www.women.org/BreastCancer). Higher breast densities have proven to make current breast cancer imaging and detection more difficult. A pilot study done at the Huntsman Cancer institute showed that the ultrasonic parameter peak density, generated by high-frequency (HF) ultrasound (20-80 MHz), was sensitive to breast tissue pathology. The objective of this study was to determine the effect of breast density on ultrasound wave propagation from high frequency ultrasound using phantoms that mimic the histology of breast tissues. Phantoms were created from a mixture of distilled water, agarose powder, and 10X TBE stock solution. In order to simulate breast tissue histology and breast density, polyethylene microspheres were embedded into the phantoms in layers, totaling 4 layers per phantom. The polyethylene microsphere size (90-106 μm diameter) was kept constant within each phantom while the weight percent concentration of the microspheres varied (0.00g to 0.06g). Pitch-catch and pulse-echo measurements were acquired using 50-MHz transducers (Olympus NDT, V358-SU, 50 MHz, 0.635-cm diameter active element), a HF pulser-receiver (UTEX, UT340), and a 1-GHz digital oscilloscope (Agilent DSOX3104A). Glycerol (Genesis Scientific) was used as a coupling agent between the transducers and the phantoms. Spectra were derived from the data, giving peak density (the number of peaks and valleys in a specified spectral range), velocity, and attenuation values. The results showed that peak density did not start to show a trend until phantoms of 0.03g concentrations, where it increased from a value of 14.0 peaks (0.03g) to 18.7 peaks (0.06g). Velocity showed a statistically significant increase with greater polyethylene microsphere concentration, from 1508 m/s for 0.00g to 1536 m/s for 0.06g. No trends were observed for attenuation. These results indicate that higher levels of scattering centers in dense breast tissues will be detectable with high frequency ultrasound. This additionally shows that high frequency ultrasound may also be sensitive to greater amounts of connective tissue present in dense breast pathologies. High frequency ultrasound is sensitive to the weight percent of polyethylene microspheres. Future research is planned to further understand this relationship, including repeat studies and studies of phantoms containing chopped polyethylene fibers and triple the polyethylene microsphere concentrations to more closely simulate dense breast tissues.

According to the 2010 US Census, the Hispanic population in Ogden City, Utah has grown by over 36%. This influx of population of Hispanic descent has influenced local businesses to begin advertising in Spanish through multiple mediums. To determine what factors influence a business’s decision to advertise in Spanish, locations of all print advertising in Ogden were determined through personal investigation. Second, neighborhoods and areas were divided according to census divisions that appear on the official website and median household income as well as the population of Hispanic people was recorded to determine if socioeconomic bias was present in the selection of where to advertise in Spanish. A linear regression comparing the total number of Spanish advertisements found in each geographical area was compared first to income, and then to total Hispanic population. The results of the regression illustrate a potential bias based on financial circumstances rather than ethnicity. Further study is needed to determine if this use of Spanish-advertising in the low-income areas affects Spanish-speakers’ access to healthy foods, housing, or other critical aspects of quotidian life.

Jeremiah Rundall, Utah Valley University Physical Sciences The practice in hydrology is to deduce stream discharge from stream stage by creating a rating curve for each stream site from simultaneous measurements of stage and discharge. If a river could be assigned a generic rating curve with a small number of parameters, the cost of developing rating curves could be reduced. The first step has been to classify rivers according to whether there is a unique relationship between stage and discharge. The USGS National Water Information System database of about 3.8 million simultaneous measurements of stage and discharge at15,345 active and historic stream gaging sites was imported into a Python-driven data manipulation script. Linear relationships between z-scores of the logarithms of stage and discharge were developed for each site. A frequency spectrum of the slopes of the linear relationships was created by summing the normal distributions for each site with mean equal to slope and standard deviation equal to uncertainty in slope. There were no stream gaging sites at which discharge changed without a change in stage. At about 70% of stream gaging sites, over 90% of the variation in stage corresponded to a variation in discharge. At the remaining sites, significant variation in stage occurred without a variation in discharge. Current research involves identifying the characteristics of stream sites that lack a unique stage-discharge relationship and creating classes of generic rating curves by considering more complex functional fits.

Amy Fair Brother, Utah Valley University Physical Sciences Results from a 2010 pilot study indicated that multiple parameters in high-frequency (HF) ultrasound spectra (20-80 MHz) correlate to a range of tissue pathologies in surgical margins from breast conservation surgery (BCS). One of these parameters, peak density, was particularly effective at discriminating between normal, atypical, and malignant patholUtah Conference on Undergraduate Research 2015 100 ogies. Subsequently, Utah Valley University and the Huntsman Cancer Institute initiated a follow-up study to further investigate this approach. Objectives: The purpose of this study was to determine the sensitivity and specificity of HF ultrasound for differentiating malignant tissue from normal tissue in BCS surgical margins. Methods: A 73-patient blind study was conducted with conventional pathology used as the gold standard for assessing the HF ultrasound method. Specimens were delivered by the surgeon’s team immediately following resection and ultrasonically tested outside the surgical suite. The margins were approximately 3x20x20 mm, and were oriented using a small staple inserted by the surgeon in one corner and a stitch on one side. The margin was tested at 2-5 locations on the specimens using our methodology and then sent to pathology for their analysis. 498 specimens were tested from 73 patients. That corresponded to 1112 positions collected from the margins. The data was then analyzed for malignancy using peak density, and then correlated with the traditional pathology. Results: Results from the current study indicate that peak density can differentiate between malignant and nonmalignant pathologies with an accuracy of 73.8%. The correlation between pathology and peak density has a high level of statistical significance compared to random chance, with p = 0.000078 (Fisher’s Exact test). The results also provide data for improving the technique. For example, approximately 3 times more false positives were observed than false negatives, indicating the peak density threshold used for identifying malignant pathology is most likely too low and should be adjusted to a higher value. Conclusions: Results from this study showed that HF ultrasound has the potential to provide rapid, intraoperative evaluation of surgical margins, thereby decreasing the number of additional surgeries for patients and thus increasing the quality and efficacy of surgical treatment for breast cancer.

Eric Johnson, University of Utah Physical Sciences The ability to reduce O2 in mild conditions holds many important implications such as: use as an economical fuel cell, pharmaceutical synthesis, biomass degradation and conversion of small molecules to fuels. We are building the [M(μ-OH) (oxapyme)M(H2O)]+ molecules and symmetrical counterparts for use in O2 reduction reactions (M = Cobalt, Nickel, Iron). The precursors to the [M(μ-OH)(oxapyme)M(H2O)]+ have been synthesized as follows. 2-[5-(2-Nitro-phnyl)-[1,3,4]oxadiazol- 2-yl]-phenylamine serves as the backbone of the complex, allowing for two distinct ligands to be attached to each side. Initial yields for this synthesis averaged at 6%. To be able to complete the synthesis this needed to be significantly raised. The literature procedure was modified in various ways until new reaction conditions were found that allowed for 40% yield. Other precursors include 2,2’-(1,3,4)Oxadiazole-2,5-diyl-bis-aniline which also serves as a ligand backbone but differs in that it allows for preparation of a symmetrical ligand have been synthesized with a 51% yield. The first ligand Bis-pyridine-2-ylmethyl-amino has been produced with a 60% yield. The second ligand Methyl-pyridine-2-ylmethyl-amino has been synthesized with an approximate yield of 75%. These yields are high enough to finish the synthesis of the ligand and subsequently coordinate the metals. Upon completion, the electrochemical properties of the compounds that differ in the metal composition and the ligand (symmetrical versus asymmetrical) will be determined using studies such as cyclic voltammetry. Once the metal and ligand that are most apt at oxygen reduction is determined, more advanced studies will be undertaken to identify the reaction mechanism and intermediates.

Paul Robertson, Utah Valley University Physical Sciences Evaluation of Utah Valley University’s stormwater plan reveals a simple system meant to collect stormwater into the city storm drains as quickly as possible. It is, however, vastly underdeveloped and many unspectacular summer and springtime storms have resulted in property damage, including those of nearby residents. The stormwater runoff has also collected concentrated amounts of hydrocarbons, nitrogen and heavy metals which are being fed directly into Utah Lake, acting as a significant source of pollution for the lake environment. The intentions of this project are to design a stormwater management plan that can withstand a 100 year, 24 hour event and prevent pollutants from entering the Utah Lake system. Mapping and modeling of the University’s storm drains will be accomplished using GIS as well as modeling for efficient retention sites on campus. Captured stormwater will then be used for a variety of functions here on campus and runoff into the adjacent lake will be reduced to insignificant values. Decisions regarding the ultimate implementation of this project will work in concordance with the University’s master plan of future development in order to realistically secure a reliable, low-maintenance system.

Madeline Parson, Travis Bulloch, and Tyler Argyle, Southern Utah University Physical Sciences Lipid bilayers have many important purposes in living cells. A lipid bilayer forms a barrier which separates the fluid inside the cell from the fluid surrounding the cell. The arrangement of components within cell membranes can be extremely important, particularly in cell communications. For example, when our immune system attacks certain pathogens, it recognizes them by specific proteins in the inner and outer regions. This can be thought of as forming a “bull’s-eye” shape. The ability to generate such patterns in bilayers might see applications in many areas of biology. Our goal is to take an initially un-patterned supported lipid bilayer (model cell membrane) and use magnetic tweezers as a delivery system to generate patterns. We hope to show pattern formation using fluorescent-labeled lipids within our bilayer. In the past, we have used streptavidin and biotinylated lipids with Oregon Green. Currently, we are pursuing a fluorescein/anti-fluorescein system that has been yielding much more promising results. We are currently using a fluorescent microscope to confirm that patterns are forming within the bilayer.

Henintsoa Rakotoarisaona, Utah Valley University Physical Sciences The Jordan River is the only outlet of Utah Lake. Historically, this area has been impacted by urbanization, long term mining operations, industrial and agricultural activities resulting in potentially high levels of trace metal pollutants at the headwaters of the Jordan River. Since trace metals are known to be toxic at elevated levels, it is important to evaluate their concentration, distribution and mobility in this sensitive area in order to determine risk to wildlife, humans and downstream users of the Jordan River. Three core samples from 0 cm to 95 cm in depth were collected at the east (industrialized area), west (newly developed area) and north (an island barrier) sides of the outlet of Utah Lake. Each sample was digested in triplicates in the Microwave Accelerated Reaction System (MARS) using US Environmental Protection Agency Method 3052 and analyzed in the Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) for As, Cd, Cr, Mn, Pb, Cu, Zn, Co, and Ni. A multivariate analysis of variance (MANOVA) was used to analyze the data, with a boneferroni adjustment made for multiple comparisons. The results indicated that the East and North sediments of the Jordan River were significantly (P < 0.5) more heavily impacted by trace metal pollutants than the West side, with the North area accumulating higher levels of the majority of the trace metals or metalloid evaluated. Enrichment of Co, Cr, Pb and Zn was observed on the East sediment at concentrations reaching 10,821, 4.07, 13.7, 12.7, 119.4 mg kg-1, respectively. The most substantial elevation in the concentration of trace metals occurred with Cu in the North section of the lake, increasing from 349 mg kg-1 at 0-15 cm to 1383 mg kg-1 cm depth, showing high mobility, followed by Zn which increased from 46.7 mg kg-1 at 0-15 cm to 592 mg kg-1 30-45 cm depths. The enrichment of these trace metals in the East and North sediments at the outlet of Utah Lake pose a health risk to animals and humans who use these areas for recreational or agricultural purposes.

Benjamin Finch, Utah Valley University Physical Sciences The Breast Cancer Research Laboratory at Utah Valley University has been using high-frequency ultrasound to test the pathology of surgical margins from breast cancer conservation surgery. Their studies have shown that high-frequency ultrasound may be sensitive to a range of breast pathologies. The ultrasonic parameter that has been shown to be the most sensitive to pathology is the number of peaks (peak density) in the frequency spectra from the captured waveforms. During testing, the ultrasonic transducers apply an amount of force to the tissues that can vary depending on the researcher. The central question of this study was to determine the effect that the applied force has on the final peak density reading, and therefore the reliability of the results. In order to determine the correlation of force and peak density, an experiment was designed to measure the force applied to tissue by the ultrasonic transducer during testing and to simultaneously measure the applied force while collecting ultrasonic waveforms. An Arduino Uno R3 instrument was obtained as well as an Interlink Electronics FSR 406 force sensor pad. The Arduino was programmed to read the voltage from the FSR sensor and use that information to provide force (N) and pressure (N/cm2) data from the stage. Peak density readings from bovine mammary tissue (very similar to human breast tissue) were acquired using varying amounts of force. The results obtained exhibited significant changes in peak density with applied force. The results showed that if the applied force is under 1.18N, the peak density will fluctuate significantly and will therefore give inconsistent results. However, if the force applied is greater than 1.18N, the peak densities will maintain a relatively consistent form. In conclusion, if the force applied during testing is above 1.18N, the waveforms captured from high-frequency ultrasound testing on breast cancer tissues will provide consistent and reliable results, thus improving the quality of the data and accuracy of diagnosis.

Cameran Mecham, Utah Valley University Physical Sciences Introduction:

Michaelle Cadet, Utah Valley University Physical Sciences Breast cancer is the most common cancer among women in the United States. Tumor angiogenesis and its inhibition is an important aspect of oncology and the treatment of cancer. High-frequency ultrasound (10-100 MHz) is particularly sensitive to small vascular structures that are close in size to the ultrasound wavelength (15-150 _m). The ability to rapidly determine the degree of vascularization in small animals in vivo would provide a useful characterization tool for breast cancer studies. The objective of this study was to determine if direct ultrasonic measurements in the 10-100 MHz range could be used as a vascularization assay for breast tumors and other tissues. To accomplish this, six mice from the Huntsman Cancer Institute (Salt Lake City, Utah) with grafted breast cancer tumors (three control and three treated with an angiogenesis inhibitor called Avastin) were tested in vivo using through-transmission ultrasonic measurements. A second study was also performed at the Ludwig Boltzmann Institute for Experimental and Clinical Traumatology (Vienna, Austria), where the femoral artery in one hind leg of each of sixteen mice was ligated and tested over the time period of eight days. Eight of the ligated limbs were treated with vascular endothelial growth factor (VEGF) while the remaining eight ligated limbs were allowed to grow ischemic. The unligated limbs were controls. Results from the Huntsman Cancer Institute study indicated that breast tumors in Avastin-treated mice showed higher ultrasound velocities than control tumors. This can be ascribed to the vasculature in the nontreated tumors creating greater wave scattering in the tissue, thus decreasing the velocity. Results from the Boltzmann Institute study indicated that in mice with ligated femoral arteries, ultrasonic signals from ischemic limbs displayed a decrease in wave velocity over the test period as compared to the VEGF-treated limbs. However, both the ischemic and VEGF-treated limbs showed decreases in ultrasonic attenuation during the entire test period. Results from Avastin-treated mouse tumors and mouse limbs with ligated femoral arteries revealed that high-frequency ultrasound holds potential for measuring angiogenesis in vivo.

Nicole Cowan, Utah Valley University Physical Sciences Breast cancer is the second most prevalent cancer among women, affecting one out of eight women in their lifetime. The ability to differentiate between malignant and normal tissues during breast cancer surgery would enable the surgeon to remove all of the cancer from the affected region in the breast, thereby reducing the risk of recurrence and the need for subsequent surgeries. A pilot study conducted at the Huntsman Cancer Institute showed that high-frequency ultrasound (20-80 MHz), and in particular the ultrasonic parameter peak density, was sensitive to breast tissue pathology. The objective of this study was to determine the effect of tissue microstructure on peak density using phantoms that mimic the histology of breast tissue. Phantoms were created from a mixture of distilled water, Knox gelatin, and Metamucil fiber. In order to simulate breast tissue histology and terminal ductal lobular units, polyethylene microspheres were embedded into the phantoms in layers, totaling 4 layers per phantom. The volume percent of polyethylene microspheres was kept constant in each phantom while varying microsphere sizes (58-925 μm diameter). Pitch-catch and pulse-echo measurements were acquired using 50-MHz transducers (Olympus NDT, V358-SU, 50 MHz, 0.635-cm diameter active element), a HF pulsar-receiver (UTEX, UT340), and a 1-GHz digital oscilloscope (Agilent DSOX3104A). Glycerol (Genesis Scientific) was used as a coupling agent between the transducers and the phantoms. Spectra were derived from the data, giving peak density (the number of peaks and valleys in a specified spectral range) and attenuation values. In a previous study, histology- mimicking phantoms were fabricated where the weight percent of polyethylene microspheres was kept constant, but the microsphere diameter was varied. The former study showed a clear trend of higher peak density values for smaller diameters, but no trend for attenuation. In contrast, the phantoms from this study showed no trend in peak density, but a clear trend of higher attenuation values for larger microspheres. The results show that specific changes in tissue microstructure affect the parameters of peak density and attenuation differently. Changes in the number of scatterers and in their size, as in the previous study, affected peak density most significantly. In contrast, changes solely in the size of the scatterers, but not in their number, affected attenuation most significantly. These results are consistent with attenuation results for lobular carcinoma in the pilot study. These results show that peak density and attenuation are complementary parameters, and could be used together to characterize a variety of tissue pathologies

Jennifer Melvin and Wendy Schatzberg, Dixie State University Physical Sciences The general chemistry laboratory can be a dangerous place, and the possible danger is amplified by the fact that general chemistry is frequently a student’s first chemistry laboratory experience. College students come from a variety of backgrounds with only some having had chemistry in high school, and therefore many students will not know beforehand what kind of precautions to take or what kind of action to take in case of an accident in the lab. Safety information is given briefly at the beginning of the semester, but the efficacy of this is uncertain. An online survey was conducted to gauge first- and second-semester general chemistry students’ knowledge about chemistry laboratory safety and the data gathered was analyzed. This survey was conducted at two secondary schools in two different countries. Statistical analysis will be presented. Results will allow discernment of misconceptions held by students over two semesters and between countries, and conclusions can be made about the effectiveness of current laboratory safety instruction methods.

Brett Barton, Dixie State University Physical Sciences Dissolution using ionic liquids has been shown to be an efficient analytical method of dissolving keratin fibers. Using wool and hoof material from livestock, chloride-based ionic liquids were used to break down the hydrogen bonds important for keratin structure, making the extraction of constituent material much easier. Efficient methods of extraction allow for small samples to be analyzed while still providing high yields; efficient dissolution of keratin in a small sample size will be utilized to prevent any harmful effects on the animals. Ionic liquids are nondestructive solvents which allow for the safe extraction of organic substances. Denaturing keratin would help in the process of identifying any constituent radioactive materials. Efficient identification of radioactive material in livestock is crucial for maintaining health and quality of life.

Tim Beach, Utah State University Physical Sciences Successful management of the arid West requires a basic knowledge of available water resources, withdrawals, and existing management efforts. Utah, the second driest state in the country, is continuing its efforts to restore impaired water systems and teach the next generation to conserve water. Because of a fast-growing population, the diversity of Utah’s landscape, and strict regulations that govern water throughout the state, understanding the region’s current water condition can be difficult. Historically, the majority of this information has been stored in databases, represented by only numbers and statistics. In an effort to better conceptualize this data and increase the spatial understanding of Utah’s water, a set of maps have been produced. These maps were created using ESRI’s ArcMap software and Adobe Illustrator. Included are major lakes and rivers, average annual precipitation, average annual streamflow, total urban withdrawals per county, total agricultural withdrawals per county, and water management. Viewing visual representations of this information in multiple maps can aid in creating spatial inferences, and raise additional questions regarding aquatic restoration and management throughout the state. This set of maps can also be used to supplement physical science education at all school levels. Future work includes distributing these maps as posters to schools and water managers, as well making it a resource for teachers via websites and fact sheets.

Melinda Hurlbut, Dixie State University Physical Sciences A newly discovered plant fossil locality in the Chinle Formation (Upper Triassic) in Washington County broadens the distribution of known Late Triassic plant fossil localities to include southwestern Utah. Previously reported plant localities in the Chinle Formation are known from southeastern Utah, Arizona, New Mexico, and equivalent strata from the Dockum Group in Texas. The majority of the known plant fossil localities are from higher stratigraphic units of the Chinle Formation. However, the new Washington County locality is from the older, basal unit, the Shinarump Member. The plant fossils identified from the new locality include fronds of the fern Phlebopteris sp., fertile leaves of the fern Cynepteris sp., and leaves of the bennettitalean Zamites sp. Undetermined species of conifers are represented by a partial branch and a three- dimensionally preserved cone containing well preserved seeds. The diversity of species found at the Washington County plant fossil locality correlates with other known floral assemblages from the Chinle Formation, suggesting general homogeneity of Chinle Formation floras. These plant fossil assemblages support interpretations of basal Chinle Formation paleoclimates as humid and warm.

Kyle Marcus, Cami McKellar, Riley Pearce, Shay Beck, and Zenja Draca, Dixie State University Physical Sciences Invasive marine and freshwater species have a detrimental impact on aquatic ecosystems and are easily transferred between bodies of water as a result of unregulated settlement and attachment to commercial and recreational watercraft. This results in infestation of waterways and disruption of native organisms throughout an ecosystem. The quagga mussel (Dreissena rostriformis bugensis) is one example of such invasive species that has called for a focus on cross-contamination prevention. The goal is to use aquatic paint suitable for watercraft that prevents the settlement and/or attachment of various aquatic species such as algae, snails (Physa sp.), anemones (Aiptasia sp.), and quagga mussels. The paint is integrated with newly developed surfactants that act as an inhibitor to the adherence ability of invasive aquatic species. The surfactants are added to provide a barrier between the paint surface and the organisms creating an undesirable surface area for the organisms to attach. This barrier disrupts the specific naturally occurring chemical and physical processes that allow organisms to adhere to surfaces. The most innovative characteristic of the surfactant-based paint is its effectiveness on adherence inhibition without degradation, dissociation, or toxicity to the environment. Preventing adherence of invasive organisms to surfaces could have significant positive effects on the efficiency and cost of operations in marine environments and waterways.
