The Triple Discrimination of Indigenous Mayan Women Today
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.
Religion in Young Adult Contemporary Realistic Fiction
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.
A Tide Just West: An Artist Book of Ecriture Féminine, Photography, and New Narrative
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.
Hysteresis and Motor Planning in Children with Autism Spectrum Disorder
Daisha L. Cummins, Kodey Meyers, and Breanna E. Studenka, Utah State University Health Children with Autism Spectrum Disorder (ASD) exhibit rigidity of motor plans and difficulties planning and executing movements (Eigsti et al., 2013). Those with ASD may also have difficulty formulating new or switching between different motor plans. In typically developing individuals, sequential actions exhibit hysteresis, a phenomenon where a specific motor plan is influenced by recent, similar motor actions. We sought to determine if hysteresis was stronger in children with ASD. A rotation motor task measured the rigidity of motor planning (hysteresis) of five ASD children, and 5 control participants. A stick was placed in one of 24 different orientations around a circle. The researcher moved the stick counterclockwise or clockwise in subsequent trials. A participant grasped the stick and returned it to the home position. Researchers measured the position at which the child switched from a thumb up to a thumb down grasp in each direction. The peak counterclockwise switch occurred later for children with ASD. The grasp also changed less frequently for the ASD than for the control group. Our results suggest that changing a grasp was more costly than being comfortable, and that hysteresis was more prevalent in children with ASD than in the control group.

The Effects of Sexual Assault on Memory and Consciousness: A Retrospective Chart Review
John Rossi, Julie Valentine, Leslie Miles, Linda Maybe, and Julie Melini, Brigham Young University Health The purpose of this study is to explore the effects of sexual assault on memory and consciousness in 314 victims in a Mountain West community using retrospective chart review. Altered mental awareness and/or loss of consciousness during a sexual assault are widely unexplored phenomena. A majority of assaulted individuals experience a varying degree of loss of consciousness during an assault – resulting in memory loss and conflicting evidentiary reports creating challenges during an investigation and prosecution. Statements written by a forensic nurse based on patients’ telling of the sexual assault (analyzed in Nvivo10) were placed within the following categories: memory loss; decreased feelings of mental alertness or awareness; symptoms of tonic immobility; detachment from self, environments and/or situation; reports full loss of consciousness; and/or awoke to assault. Quantitative data from patients’ answers to questions related to their memory of the nature of the assault was analyzed through descriptive statistics in SPSS, resulting in the following statistics: 58.3% reported having a loss of consciousness or awareness, 54.2% reported “unknown” to 1 or more questions about the nature of the assault, 37.8% reported “unknown” to 4 or more questions, 17.3% reported “unknown” to all questions. Additionally, a Chi square test for independence found patients with memory loss/altered consciousness were associated with the following variables: patients with mental illness and/ or use of psychotropic medications (p=0.025) and use of alcohol prior to assault (p=0.000). Medical teams, law enforcement, and judicial representatives must understand the impediments associated with a victim suffering from altered mental status caused by neurobiological and psychophysical effects of sexual trauma; thus, creating an atmosphere that avoids re- traumatizing a patient and providing for optimal care. This research will supplement other studies focusing on neurobiology/sexual assault trauma and foster greater understanding of the effects of sexual assault on memory and consciousness.
Learning History: Understanding Organizational Learning in a Hospital
Kalene Mears, Brigham Young University Health The purpose of this project is to compile a learning history for a hospital unit, documenting patterns of past adaptation within a clinical microsystem that can be magnified to help the system continue to improve. The goal in healthcare is to create an adaptable system, where changes are continuously made as problems are identified to prevent harm from care. Through a learning history, a hospital unit can identify how they have already solved problems in the past and identify patterns of adaptation that can be replicated to increase reliability within the organization. This project has the potential to help a hospital unit improve its reliability in providing quality patient care and reduce preventable patient harm. To obtain the information about the unit’s history, key team members will be interviewed using an appreciative approach to identify strengths and patterns of successful adaptation. Interviews will highlight positive features of this team to foster feelings of success and achievement, promoting desire to continue improvement. Clinical data will supplement the interviews to show a full picture of how the unit adapted to its situation. The transcribed interviews will then be distilled to highlight the critical, meaningful points in the plot line where learning and adaptation took place. This resulting manuscript is the tangible learning history. Internal dissemination will involve sharing the learning history with the organization and facilitating group discussions about the findings with members of the organization. Through this process, we anticipate the unit will be able to promote more effective interventions to improve patient care.
Are We as Healthy as We Should Be? A Comparison of Income and Diseases of Affluence
Cody Craig and Charles Yeager, Snow College Health Logically, a rise in income should lead to a healthier population. Diseases like malaria, cholera, and HIV/AIDS are associated with poverty, low rates of education, and poor infrastructure in many parts of the world. In populations with higher per capita income (or “wealth”), these diseases are not as common. However, while our higher socioeconomic classes have fewer poverty linked diseases, is the overall health of people across Utah as high as we might expect it to be? Diseases like obesity, heart disease, and diabetes (known as diseases of affluence) are becoming more and more common, even though advanced health technology and healthcare availability increase. This project will examine the relationship between income level, diseases of poverty, and diseases of affluence. Data will be aggregated from a number of sources and mapped using a geographic information system. A regression analysis will be conducted to determine if variables are positively or negatively correlated with diseases of poverty and affluence in Utah.

The Contribution of Patient Size and Backscatter to Dose in Diagnostic Imaging
Delena Hanson, Dixie State University Health Debate in diagnostic imaging over the effectiveness of shielding the patient from the incident (primary) beam compared to shielding from the scattering beam once it has hit the image receptor is ongoing. Because radiation in any amount can cause long term effects, it is the ethical obligation of those in the profession to keep the dose of radiation to the patient as low as reasonably achievable. Backscatter is radiation that goes through the patient, contributes to the diagnostic image, then still has enough energy to hit the image receptor and scatter back toward the patient. While previous studies indicate that dose to the gonads from the primary beam during chest x-ray exams are low, this additional research assesses the amount of backscatter that happens during a chest x-ray to determine at what point patient size is a factor that increases patient dose. As more technique must be used for larger patients, increased interactions will occur and therefore present a higher probability of backscatter that can add to the patient’s gonadal dose. This research quantifies whether and at what point placing a lead shield between the patient and the image receptor will reduce dose to the patient by measuring the thickness of a patient receiving chest x-ray and using a pocket dosimeter to measure the amount of radiation scattering back from the patient to compare with data from the incident beam.
Blood Lines: Flash Narrativ e Technique and Creative Nonfiction
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.
Culture, tourism, and economics: An analysis of tribal lands in Utah
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.
The Desert as an Objectiv e Correlative: A Creative Writer’s Perspective
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.
Traumatic Brain Injury: An Argument for Awareness
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.
Investigating the Bilingual Advantage in the Discrimination of Thai Stops
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.
Blood and Ink
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.
Ho Chi Minh Friend or Foe? New Revelations from the Pentagon Papers
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.
Beneficial Medical Service and Surveys in Nicaragua
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.
To Kill a Rooster
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.

The Treacherous Narrator of Henry James’ Washington Square
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.
Yellow Monster in the Heart of Dinétah: Uranium Profiteering and the Poisoning of the Navajo Homeland
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.
Profiting from the Middle Passage
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.
Kalashnikov Enculturation: The Soviet Contribution to Small Arms Proliferation and the Disintegration of the Non-State Threshold
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.
How Video Games Revolutionize Storytelling: The Uniqueness of Gaming Mechanics, Buttons, and Ana-log Sticks
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.

Attribution-based Training for Evidence-based Practices: Reducin g Recidivism through Organizational Change
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.
Attitudes Towards Cross-caste Marriage in Visakhapatnam, India
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.
An Improbable Inn: Texts and Traditions Surrounding Luke 2:7
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.
Incorrect Perception of Crime on Campus as a Result of Cell Phone Use
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.
International Teaching Assistant Accent Adaptation Study
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.
The ‘B’ in LGBTQ
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.
Electronic Cigarettes
Jamie Slade, Utah Valley University Health Electronic cigarettes (e-cigarettes) are gaining in popularity. Unfortunately, this increase is occurring at a time when we lack a definitive understanding of the health hazards. It is important for professionals to understand e-cigarette users’ experiences and satisfaction with the devices in order to determine what may entice users to begin and continue using these devices.
Russian Student Nurses Collaboration: A Learning Adventure
Abigail Harris, Brigham Young University Health Purpose:
HiFidelity Simulation in Nursing Lab
Tianne Pierce, Utah Valley University Health Since Mario and Zelda (Nintendo video games), video interactive games have been a favorite babysitter for the past two generations of children, simulation is no stranger to this population. Portions of this population became nursing students. Simulation in health care is second to none in the ‘hands on’ teaching of skills; thus, it would be the natural order of things to include interactive figures and scenario during teaching and learning in nursing. Utah Valley University’s nursing department employs the use of human simulators in the delivery of content to the students. It is no surprise that these students relate well to simulation in the classrooms. The purpose of the research study will be to compare students’ responses to learning in a teaching environment void of simulation vs. a teaching environment which uses simulation. Although simulation has long been used in aviation and the military, it has become more integrated in the health care profession over the last 20 years. These study results were congruent with national and international landmark studies where the use of simulation in nursing has been supported by the world of healthcare.

A Pollution Solution: Indoor Air Quality of St. George, Utah
Whittni O’Brien, Dixie State University Health St. George residents are currently at risk from poor indoor air quality. The objective of this study was to provide citizens with simple solutions to purify their indoor air and avoid the side effects of pollution. The rising threats include benzene, formaldehyde and trichloroethylene. These carcinogens are directly linked to heart disease, birth defects, asthma and premature deaths in individuals. The study was conducted to see just what could be done to combat these hazards and provide the necessary information to resolve the levels of indoor air pollution to residents. A standardized questionnaire was issued to find out how educated locals were about the pollution levels and air quality within the community. Questions covered a variety of aspects including exactly what the threats were to specific methods of indoor air purification. To reduce the number of carcinogenic related health issues, participants were provided with a pamphlet including easy to follow steps to cleaner indoor air and outdoor air pollution. The objective result yielded plants to be the best solution. Aloe vera plants are not only grown locally, but are easy to propagate. These plants are known for their ability to remove formaldehyde from the air and therefore an inexpensive and readily available resource that will assist residents. Other solutions found included greenery such as moth orchids, snake plants and the ficus tree. All of these plants are easy to maintain with local climate conditions. By providing residents with the proper education and resources, the overall health of the population will rise. The conclusion of the study offers vital knowledge to the community and a progressive approach to cleaner indoor air for a healthier living space.
Understanding the Importance of Intraosseous Therapy
Erika Brown and Stacie Hunsaker, Brigham Young University Health Health care professionals are often challenged with starting an intravenous (IV) line in patients who are dehydrated, have suffered trauma, or are in shock. Nurses and physicians can become frustrated by the multiple attempts and patients can lose valuable time. An alternative route to deliver the needed fluids and medications to these critical patients can be achieved by accessing the blood supply inside the bone. Intraosseous (IO) access is a safe, rapid, and an effective alternative method to deliver medications and fluids to these critical patients (Hunsaker and Hillis, 2013). I was mentored in the practice of qualitative research and interview process in a study related to difficult IV access. A qualitative research study was performed at Hospital Luis Vernaza in Guayaquil, Ecuador, to determine the complications faced in providing timely care to critical patients, and to assess their knowledge and use of IO therapy. Interviews were performed, and, because of my fluency in the Spanish language, I was the primary interviewer. These interviews were analyzed to assess the need of interventional IO therapy. Through the interviews, preliminary results demonstrated a need for an organized IV algorithm in this large hospital. The difficult IV algorithm has been developed and will be presented to the health care professionals at Hospital Luis Vernaza in the spring of 2015 on a Brigham Young University College of Nursing Global Health stay in Guayaquil, Ecuador.
The Effects of RaLight on Stress
Paydon Newman and Joseph Rebman, Dixie State University Health Several studies (Shepley, 2012; Sherman-Bien, 2011; Walch, 2010) have found that sunlight has a stress-reducing effect on those who are exposed to it. An innovative new design of artificial lighting known as RaLight is proposed to reflect light with a color rendering index nearly identical to natural sunlight. This study will examine the relationship between exposure to RaLight (as a substitute for sunlight) and levels of stress. RaLight is predicted to decrease levels of stress in test subjects. In a commercial call center setting, test subjects will consist of an estimated 50 employees both male and female with ages ranging from 18 to 30 years. This research is designed as a single subject experiment (ABA). The initial control condition will be the common indoor environment which exposes patients to standard fluorescent lighting. Replacing light fixtures with RaLight will then establish both the second phase of the experiment and the independent variable. A follow up re-installment of the initial fluorescent lighting will be conducted post-RaLight phase. Throughout each phase, questionnaires regarding the overall well-being of employees will be completed.
Economical Rapid Production of Therapeutic Proteins using Cell -free Protein Synthesis
Hayley Ford, Kristen Wilding and Matt Schinn, Brigham Young University Engineering Therapeutic proteins are specially engineered proteins used to treat many large profile diseases. Such diseases include cancer, diabetes, hepatitis B/C, hemophilia, multiple sclerosis, and anemia. The use of these proteins is specific and highly successful and the demand for these proteins in rapidly increasing. One of the largest problems with the use of therapeutic proteins is the cost of making them. The cost of producing these proteins amounts to hundreds of billions of US dollars every year. There is a growing need to find better, faster, and cheaper ways to create them. As specific therapeutic proteins are coming off patent, research labs are able to explore the processes of making these drugs that have become such a large part of the pharmaceutical industry. Here we report the use of cell-free synthesis as a more cost-effective way to produce these therapeutic proteins. Cell-free protein synthesis is faster and allows for direct manipulation and control of the protein creating environment. Cell-free synthesis can produce proteins in a matter of days as opposed to the weeks it takes to produce them in vivo. The increased manipulation and control of the environment that comes with cell-free synthesis allows improved accuracy in creating the desired proteins and is more adaptable to changes if they need to be made.
Characterization of the Role of Oxytocin in Larval Zebrafish Behavior
James Newton, Scott Anjewierden, and Sasha Luks-Morgan, University of Utah Engineering Oxytocin (OXT), a neuromodulatory peptide produced by the hypothalamus, is involved in a variety of physiological and behavioral phenomena. Exogenous OXT and drugs that mimic OXT signaling are potential treatments of a number of neurological disorders. The canonical mechanisms of OXT function are neuroendocrine in nature, as the peptide is released into circulation through the neurohypophysis. However, OXT has also been shown to exert some of its effects through direct synaptic release within the central nervous system. Using the larval zebrafish as a model, we seek to identify targets of these directly projecting OXT neurons and study what role they play in the modulation of behavior. Critical to this analysis are computer programs which enable precise quantification of anxiety, social behavior, and reward learning. Our custom-written software automatically identifies and tracks free- swimming fish, using measured positions over time to evaluate behavior in a variety of paradigms. In combination with molecular, cellular, and optogenetic manipulation of OXT networks, this project will allow a fuller understanding of the relationship between these neurons and behavior.

Methods for Simulating SAED and Kikuchi Diffraction Patterns in Atomistic Structures
Adam Herron, Jared Thomas, Shawn Coleman, Douglas Spearot, and Eric Homer, Brigham Young University Engineering For many years, x-ray diffraction and electron diffraction have served as effective means to understand and classify the molecular structure of many materials. Diffraction, as a physical phenomenon, is well known and theoretical diffraction simulation is relatively simple for perfect crystalline structures of known orientation. Prior methods of diffraction simulation, however, are insufficient to predict experimental diffraction patterns of unknown crystal structures or of crystal structures with high defect density. Recent advancements in computing capability and development of atomistic simulation software have greatly enhanced our ability to predict material properties and behaviors under various conditions. Atomistic simulation has become an extremely useful tool in the analysis of dynamic chemical and mechanical systems. It can only be truly effective, however, when it models a real-world application, can be interpreted coherently, and can accurately predict future conditions. Thus, we are developing new tools that bridge the gap between electron diffraction through real materials and simulated diffraction through atomistic simulations. We present a method of generating Kikuchi Diffraction Patterns from atomistic simulation data with no a priori knowledge of the crystal structure or crystallographic orientation. Our research was inspired by the recent work of Coleman et. al. 2013 and builds on their methods of calculating diffraction intensity at discrete locations in the reciprocal domain. We improve on their method by introducing an integration of the structure factor to ensure complete capture of diffraction intensity peaks while maintaining a relatively low density of sample points. This allows us to significantly reduce the required computation time on the analysis of atomistic simulation data. We use this diffraction data to generate simulated Kikuchi Diffraction Patterns.
In Vitro Cell-Free Synthetic Biology Techniques for Optimizing Protein Yields
Conner Earl, Brigham Young University Engineering The emerging field of Cell-free protein synthesis enables the efficient production of complex proteins for a number of exciting applications such as medicines that better interact with the body, vaccines, antibodies, and renewable, sustainable biocatalysts. However, progress is hampered by high costs and low yields of necessary proteins. This project is designed to improve protein yields and drive down costs by studying techniques of optimization of protein yields in Cell-Free protein synthesis. Our main area of focus is the inhibition of naturally occurring ribonucleases (RNAses) which are enzymes that degrade essential elements for protein synthesis- specifically, the mRNA used to transcribe protien. One of the techniques we intend to use for inhibition of these RNAses is by complexing the RNAse with an appropriate RNAse inhibitor protein thus limiting or eliminating its function of degrading mRNA. The aims of this research project is to: (1) Identify appropriate RNAse inhibitors (2) Design and synthesize inhibitor genes (3) Express, purify and assay RNAse inhibitors (4) Improve Cell-free protein synthesis yields utilizing RNAse inhibitors for analysis of activity and effectiveness as well as the enhancement of cell-free protein synthesis yields. Accomplishing these goals will result in more efficient systems and more accurate analysis that may lead to cheaper, more readily available vaccines and pharmaceuticals produced through Cell-free protein synthesis.
Retinal Regeneration: Implications of Müller Cell Dedifferentiation
Theo Stoddard-Bennett and Steven Christiansen, Brigham Young University Engineering Damage to the human retina is often irreversible and so currently there are no established treatments of diseases such as dry age related macular degeneration (AMD). Dry AMD results in a loss of sight because of cell death in the macula, a centralized part of the retina which contains a high concentration of photoreceptor cells. One possible treatment would be to limit the rate of cell death within the macula, however this is not a comprehensive solution. Rather, regeneration of the photoreceptors within the retina is necessary to restore sight. In current research, Müller glia cells, a major glial component of the retina, can potentially be used as sources for photoreceptor regeneration in order to combat dry AMD due to their homeostatic regulation of retinal injury. Directed reprogramming would occur through a five step process. The Müller glia would need to undergo de-differentiation to Müller glia-derived progenitor cells (MGPCs), proliferation of MGPCs, migration of MGPCs, neuronal differentiation, and integration in order to generate retinal neurons. Müller cells can be isolated and cultured by dissociating retinal tissue in optimal media. Here we present the dissection and dissociation of rat retinal tissue to obtain purified proliferating Müller cell cultures. Our lab has tracked and modelled the rates of proliferation and phenotypically characterized the stages of proliferation. Using immunofluorescence and PCR tests to confirm purity, we will then expect to run a series of assays to identify growth factors, Wnt signals and cytokines to test the effects of retinal extracellular matrix proteins on Müller cell de-differentiation to MGPCs. The focus of our current research is the identification of reprogramming mechanisms that may possess beneficial data leading to both unique strategies for promoting retinal regeneration in mammals and clinical applications for those living with dry AMD.
Modeling Shale Oil Pyrolysis: Semi-empirical Approach
Dan Barfuss, Brigham Young University Engineering Shale oil has long been seen as a source of energy that can be incorporated into existing infrastructure. It consists of kerogen (or organic matrix) bound to inorganic rock. This kerogen can be released as an oil-like substance by heating it up to high temperatures without the presence of oxygen (i.e., pyrolysis). Due to advances in NMR (Nuclear Magnetic Resonance) we were able to make an accurate structural based model that can predict the relative tar and light gas yields[1]. We modified the Chemical Percolation Devolatilization Model (CPD) of coal to fit with the more aliphatic nature of oil shale. The CPD model describes the aromatic regions as clusters and aliphatic regions as bridges. As these bridges are broken the model releases groups of clusters that will form tar. In coal the bridge breaking gives off light gases, whereas in shale oil the bridges are much heavier and mostly form tar. We built two models that accounted for this. We also used the composition of the tar and the gas found by Fletcher et. al. [2] to predict what elements would be left and the aromaticity of the carbons. We found that throughout the reaction new aromatic regions were formed. With information from this model,- we are able to better predict the products of oil shale pyrolysis, and describe what happens chemically.
Purification of Air Using Molecular Modeling and Photocatalytic Nano-Materials
Nandini Deo, University of Utah Engineering Air quality in the United States has come under scrutiny in recent years. Many pollutants are trapped in the air we breathe in the form of photochemical smog. The aim of this research is to aid the breakdown of these pollutants. Peroxyacetyl Nitrate (PAN) is a predominant smog species; the research conducted aims to decompose this molecule and capture the resulting particles using the photocatalytic properties of Titanium Dioxide Nano tubes. The research conducted thus far has focused on the following questions:What molecules does the thermal decomposition of PAN produce? Is there a metal substrate to attach to TiO2 Nano-materials that aids the breakdown of PAN and its decomposition products? Can a sustainable process/device be identified to functionalize these materials? Literature research shows that PAN thermally decomposes into CO_2, NO_2, methyl nitrate, and formaldehyde. Methyl Nitrate and CO_2 may be eliminated using specific experimental conditions. Hence, it can be determined that the substrate attached to TiO2 must decompose PAN, NO_2 and formaldehyde. Using the molecular modeling programs Avogadro and MOPAC, 50 metals were optimized in relation to Formaldehyde, NO_2, and PAN. To find each metal’s reactivity to each target compound, HOMO/LUMO (Highest Occupied Molecular Orbital/Lowest Occupied Molecular Orbital) energies were calculated and used to find the common reactive metals between the target compounds: Cobalt, Silver, Iridium, and Niobium. To test whether the most complex product of the PAN decomposition (Formaldehyde) will break down, a device was created using a 3-D printer and Cobalt functionalized nanotubes. Pure formaldehyde, a blank sample (no tubes), and a sample with functionalized tubes were run through the device in the form of vapor, in front of a solar simulator. The captured vapor’s GC/MS results show an almost complete breakdown of Formaldehyde with the use of the device containing the functionalized tubes.
Manufacture of Hemocompatible Coronary Stents
Takami Kowalski, Warren Robison, Anton Bowden, and Brian Jensen, Brigham Young University Engineering Using a coronary stent to expand a blocked blood vessel as a way to treat coronary heart disease has proved effective in the past. However, there are risks, such as thrombosis, that are a natural side effect of inserting a foreign object into the body. Creating a stent out of a hemocompatible material such as carbon-infiltrated carbon nanotubes could potentially resolve these issues and also make unnecessary treatments such as dual antiplatelet therapy as a way of decreasing the risk of adverse side effects. Previous research done in this lab has shown that carbon-infiltrated carbon nanotubes can be grown in a pattern defined by photolithography on a planar surface. The present work demonstrates preliminary results from patterning a flat, flexible substrate and rolling it into a cylindrical shape before growing carbon-infiltrated carbon nanotubes as a way to fabricate cylindrical stents, fulfilling all necessary specifications for a stent with the added benefit of hemocompatibility. We also demonstrate growth on curved substrates and explore process parameters for achieving good-quality CNT forests.
A Feasibility Study for Implementing a System of Electric Vehicles into Urban Environments
Carlton Reininger and John Salmon, Brigham Young University Engineering Electric Vehicles (EV) are a rising alternative to standard combustion vehicles because of their energy cost savings and reduced carbon emissions. However, EVs come with limitations such as limited driving range and potentially long recharge times. The purpose of this study is to determine the feasibility of implementing an electric vehicle system into an urban environment. Using data provided by the New York City Taxi and Limousine Commission, models are developed and generated to simulate driver shifts and analyze system level impacts from EVs on driver behavior. The models evaluate the number of charge events over the course of a shift and calculate the potential revenue lost to missed fares during charge intervals. Across the system, the results indicate that for a majority of NYC taxi drivers, EVs can be implemented without significant changes in driver behavior, while providing an economic and environmental advantage over current combustion vehicles. These preliminary findings can be used to support implementing such a system in urban environments and these models could be used as a template toward analyzing EV taxi potential in other cities.
