  • REPRODUCTIVE HEALTHCARE NEEDS IN HOMELESS YOUNG WOMEN: A LITERATURE REVIEW

    Parker, Sheila Hill; Tagaban, Alexa Queenie (The University of Arizona., 2019-05)
    This thesis examines the impact of unsafe sexual practices, social isolation, and lack of access to menstrual products in homeless women. A literature review was chosen to identify and summarize findings related to the reproductive healthcare needs in the homeless women population. The literature reviewed in this paper consisted of reports and studies available from academic, and government sources. The review was conducted primarily through searches in online databases, publications, and other industry resources. The primary focus of this review was to further understand the complications of unmet subsistence needs and effect on high prevalence rates of infections in homeless women. By identifying the factors that increase infection rates, it is the goal of this thesis that future programs and interventions can focus more on what homeless women specifically need.
  • ARE THERE NICOTINIC ACETYLCHOLINE RECEPTORS ON PHRENIC MOTOR NEURONS?

    Fregosi, Ralph F.; Henderson, Kimberly (The University of Arizona., 2019-08)
    Nicotinic acetylcholine receptors (nAChRs) are expressed throughout the central nervous system, including on neuron populations that control breathing. The specific locations of nAChRs on respiratory related neurons are relatively unknown and their presence on phrenic motor neurons (PMNs) could indicate a point at which developmental nicotine exposure may impact breathing. We hypothesize that application of nicotine to the PMNs will elicit changes in amplitude and area of respiratory motor bursting recorded from cervical 3-5 ventral roots due to the presence of nAChRs on PMNs. A brainstem spinal cord split-bath preparation was used to separately perfuse brainstem and spinal cord chambers with artificial cerebrospinal fluid (aCSF), and nicotinic aCSF was added to the spinal cord chamber. Burst amplitude and area under the curve were measured at baseline and during application of three different nicotine concentrations (400nM, 4M, 40M). Our results show that while 400nM nicotinic aCSF did not significantly affect the amplitude or area of bursts, both 4M and 40  nicotinic aCSF caused an initial increase in amplitude and area of the bursts, indicating nAChR activation, followed by a decrease in these parameters, indicating nAChR desensitization. These findings indicate the presence of nAChR on PMNs or neurons that synapse with PMNs.
  • The Role Of Performance Events In The Creation And Sustainability Of A Bicultural Society: A Case Study Of Maori Kapa Haka

    Blake, Emma; Leibrandt, Allison Marie (The University of Arizona., 2019-08)
    This thesis will examine how the structure of a singular competitive event can be used as a platform to create and sustain integrated biculturalism. It looks at the background forces behind the premier kapa haka event, Te Matatini, that allows it the perform this bicultural labor, in addition to looking at concrete ways in which it could improve its effectiveness. These forces stem from the connection between sport and national identity and how sporting events act as a conductor for national affiliation. Te Matatini employs most of the structural components of sports: being competitive, organized and regulated, and regularly scheduled. Changes to the experience of a spectators could be useful in broadening participation with the event, currently predominately attended by Māori, to support an integrated form of biculturalism that is often lacking in New Zealand. Some of these changes include: providing translations of events, integrating new technology for more interaction online and off, and possibly forming a competition group of Pākehā specifically.
  • READING PAINTINGS: THE INSCRIPTIONS IN THE PAINTED IN MEXICO, 1700-1790: PINXIT MEXICI EXHIBITION ANALYZED THROUGH THE LENS OF MIECZYSŁAW WALLIS

    Widdifield, Stacie; Hormel, Ana Lucia (The University of Arizona., 2019-08)
    The acclaimed 2017-2018 Painted in Mexico, 1700-1790: Pinxit Mexici Exhibition and its corresponding catalogue reintroduced the world to the paintings of eighteenth-century Mexico. Presented alongside each other, the over one hundred paintings in the collection are frequently distinguished by one element: text. This paper takes into account this unique element and examines the applicability of the typology outlined by art historian Mieczsław Wallis in “Inscriptions in Paintings,” a seminal article on the topic of painting inscriptions. Wallis defines four categories of painting inscription based on function: identification, statement, invocation, and artist statement. Analysis of the 95 inscribed paintings in the catalogue reveals that over 52% of inscriptions functioned as forms of identification, over 8% functioned as statements, over 2% functioned as invocations, and over 35% functioned as artist statements. Three conclusions can be drawn from this research: first, Wallis’ typology generally applies; second, the outliers which the typology struggles to categorize indicate refinements can be made; and third, a fifth category could be added to class didactic statements.
  • A Socio-Economic Comparative Policy Study Of Women's Access To Oral Contraceptives In The United States

    Frank, Franziska; Gallo, Jillian Frances (The University of Arizona., 2019-06)
    Aims and Objectives (i) To better understand women’s current access to oral contraceptive in the United States. (ii) Explore how women’s social and economic status can be improved with better access to oral contraceptives. (iii) Provide a policy suggestion as to how women’s access to oral contraceptives can be improved. Background This paper first provides a literature review of oral contraceptives, including the history and current regulations of oral contraceptives. A quantitative and qualitative study based off of a survey of adult women who currently use, have used, or would like to use oral contraceptives provides more empirical evidence as to why improved access to oral contraceptives is needed and what are the appropriate policy changes to be made. Design and Methods This study reports the survey responses of 93 adult women who use, have used, or would like to use oral contraceptives in the United States. Data were collected from the anonymous, consenting survey participants. All data and the analysis are backed by integrity. Results Access to oral contraceptives varies across the United States. Survey results find that women believe oral contraceptives should be easily accessible to all women either for free or at a reasonable cost. Insurance coverage and location play a role in the accessibility of birth control pills. Conclusion Oral contraceptive pills are not accessible and affordable for all women in the United States. Policy changes to consider include authorizing pharmacists to prescribe, increasing amount of pills dispensed at a single time, and making pills available over-the-counter.
  • The Exploration and Clinical Implications of Using Liquid Biopsy for Cancer Detection

    Nelson, Mark A.; Wilkins, DeAnthoni (The University of Arizona., 2019)
    Cancer is a disease the humans has been trying to eradicate for hundred of years. This disease, caused by the abnormal replication of various cells in our body, can cause a multitude of complications ranging anywhere from hormone imbalances all the way to physical obstructions of organs and organ systems. As technology begins to advance and the methods which determine how we detect, treat, and prevent cancer advance with it, it becomes possible to specify what kind of tumor the screening is being done for (benign versus cancerous) and the specific type of tumor it is in relation to its location and stage of maturation. One of the techniques which is making this degree of specificity possible is liquid biopsy which, if perfected, will provide a number of other innovate benefits for patients looking for tumor biopsies, specifically within the context of pancreatic cancer. If liquid biopsy were able to be used reliably in a clinical setting, patients would no longer have to undergo invasive procedures like surgical biopsy, and their progress through treatment would be more closely monitored and more accurate than ever before.
  • THE ROLE OF PHYSALIN F IN REVERSING EXPERIMENTAL NEUROPATHIC PAIN

    Khanna, Rajesh; Thomas, Ann Mary (The University of Arizona., 2019-05)
    Chronic pain continues to be an insurmountable issue in recent times, particularly due to the lack of adequate knowledge as well as the unavailability of appropriate therapeutics that target it. The increasingly common prescription of opioids as medication to treat chronic pain has ultimately contributed to a national opioid epidemic. In response to this, several strides have been made by the Center for Disease Control and Prevention (CDC) to revise guidelines pertaining to opioid prescription for chronic pain. This project specifically focuses on identifying the mechanism of action of Physalin F, a natural compound isolated from the Physalis acutifolia (family: Solanaceae) herb, and previously demonstrated to exhibit antinociceptive effects in models of inflammatory pain, consistent with earlier reports of its anti-inflammatory and immunomodulatory activities. Through the use of calcium imaging, it was revealed that Physalin F had a significant inhibitory effect on voltage-gated calcium channels in dorsal root ganglion. In order to replicate these findings in-vivo, Physalin F was found to reverse mechanical allodynia in both paclitaxel-induced and spinal nerve ligation-induced neuropathic pain models, further elucidating its antinociceptive behavior. Experimentation results provided a better scope on Physalin F mechanism of action as well as grounds for further investigation.
  • A PRELIMINARY ASSESSMENT OF WATER QUALITY AT THE RAINWATER-HARVESTING BASIN LEVEL IN AN URBAN SEMI-ARID ENVIRONMENT

    Whitaker, Martha P.L.; Solis Arroyo, Sheila Sarai (The University of Arizona., 2019)
    One of the anticipated benefits of green infrastructure is the capture in curb-cut basins of stormwater runoff that has accumulated urban contaminants as it runs over asphalt and pavement. These contaminants may include motor oil, pathogens, and sediments. The desert tolerant vegetation and soils within these residential rainwater-harvesting basins are expected to improve water quality by capturing these contaminants that would have otherwise flowed into local washes and recharged into the groundwater. This project reports on a preliminary comparative study of stormwater runoff quality in two Tucson washes (High School Wash and Bronx Wash) that receive runoff from neighborhoods containing rainwater-harvesting basins. The primary goal of this research project was to design a water-sampling device and protocol that accounts for variability in basins’ soil composition, successfully filters debris and soil, and collects enough sample size for water quality analysis. The secondary research goal was to conduct a preliminary comparative assessment at the neighborhood wash scales to quantify the effects of green infrastructure basins in urban areas.
  • HEALTHCARE FINANCIAL HARDSHIP AND HABITUAL SLEEP DURATION, IMPACT ON SLEEP DISPARITIES, AND IMPACT ON THE SLEEP-OBESITY RELATIONSHIP

    Grandner, Michael A.; Liang, Olivia (The University of Arizona., 2019-05)
    Introduction: Sleep is related to socioeconomics and can impact health. This study evaluated whether foregoing medical care due to cost impacts sleep and plays a role in sleep disparities and the sleep-obesity relationship. Methods: Data were obtained from the 2017 Behavioral Risk Factor Surveillance System (N=39,267 from 7 states provided complete data on all variables). Sleep duration was assessed as hours/day. Participants were asked, “Was there a time in the past 12 months when you needed to see a doctor but could not because of cost?” They were also asked for information about age, sex, race/ethnicity, education, income, employment, overall health, and access to health insurance. They were also asked for height/weight, which was used to compute body mass index (BMI). Results: Access to health insurance was not associated with habitual sleep duration. However, foregoing medical care was associated with less sleep on average (B=-0.26,95%CI[-0.35, 0.17],p<0.0005). There was an interaction with race/ethnicity, such that compared to non Hispanic Whites, the effect was 115% larger among Blacks/African-Americans, 13% larger in Hispanics/Latinos, 101% larger and in the opposite direction for Asians, and non-significant for Multiracial. Race/ethnicity relationships to sleep duration were stratified by foregoing care. Among those who did not (90%), typical relationships were seen, with both high and low sleep duration being more likely among Blacks/African-Americans and other minority groups. Among those who did forego care (10%), these effects were dramatically reduced. Further, when sleep duration was evaluated as a predictor of obesity, this relationship was only seen among those who did not forego care. Conclusion: Foregoing medical care due to cost is an independent risk factor for insufficient sleep, irrespective of income, employment, and access to insurance. It disproportionately affects Blacks/African-Americans and may represent part of the reason why these disparities exist even after adjustment for most socioeconomic indices. Further, foregoing medical care may present such health risks that this subsumes the relationship between sleep and obesity.
  • APPLICATIONS OF P-ADIC NUMBERS

    Cais, Bryden; Letizia, William Aaron (The University of Arizona., 2019-05)
    The p-adic numbers give a new technique to answer questions about the integers and rational numbers. While they are typically used in a more abstract setting, I will present two concrete applications of p-adic numbers. The major results that I will prove in this paper are that any finite subgroup of GLn(Q) must divide 24 and that the set of zeros of any integer linear recurrence sequence is the union of a finite number of finite sets and a finite number of arithmetic progressions. The latter result is better known as the Skolem-Mahler-Lech Theorem.
  • BEST PRACTICE RECOMMENDATIONS TO SUPPORT THE PSYCHOLOGICAL WELL-BEING OF INTENSIVE CARE UNIT NURSES

    Goldsmith, Melissa; Waisath, Courtney Lee (The University of Arizona., 2019-12)
    This paper will identify best-practice recommendations to help nurses better cope with demands of the field, an implementation plan, and an evaluation of the implementation process. This paper explores whether or not nurses working in the intensive care unit (ICU) experience reduced psychological well-being due to aspects of their job such as high mortality rates, ethical dilemmas, and stress. In the world of healthcare, the demand for nurses is at an all time high. However, retention rates of bedside nurses are a direct threat to this demand. The low retention rate of newly licensed registered nurses remains an ongoing challenge not only for the institution but for the quality of care provided to the patients. In 2017, the turnover rate for bedside registered nurses ranged from 6.6% to 28.7%, with a turnover rate for critical care nurses in 2017 of 16.4% (Colosi, 2018). The articles presented in this paper examine the psychological well being of ICU nurses regarding levels of compassion fatigue and burnout and further discuss the effect that high incidences of stress, high mortality rates, ethical dilemmas, and pressure on the nurses to provide their best care have on the nurse’s well-being.
  • PRECIOUS MANGROVE: AN ETHNOGRAPHY OF ENVIRONMENTAL RESILIENCE

    Sheridan, Thomas E.; Sauer, Christopher Peter (The University of Arizona., 2019-05)
    The Seri indigenous people of Mexico have been living in the desert along the Sea of Cortés for thousands of years. Their territory includes the northern most mixed mangrove estuary in Mexico. After reviewing previous literature about the Seri and the estuary, I developed a set of questions and visited their villages for interviews and a field trip. The interview topics included how their family groups are defined, what the name was of the group that used to live near the estuary, the status of who is allowed to perform songs and explain traditions, and what environmental changes they have seen at the estuary. Theories about the connection between oral history, oral tradition, and historical events, provided a framework to examine what they told me. To provide another view of this estuary, I created a Normalized Data Vegetation Index using satellite imagery from the years 2000 to 2018 that provides information about the mangrove vegetation. Instead of only being research subjects, the communities in which anthropologists engage can be considered partners. Since some of the Seri are trained paraecologists, this vegetation index will be presented to them to help in their environmental observations.
  • SEX DIFFERENCES IN MICROGLIA MORPHOLOGY IN RESPONSE TO ISCHEMIC STROKE

    Morrison, Helena; Sarinana, Victoria Cienna (The University of Arizona., 2019-12)
    In this study we assessed microglia morphology in male, pre-menopausal female, and post menopausal female mice (Male n = 5-6; Pre M n = 6; PM n = 8) following 8 hours of reperfusion, as a measurable response to injury. We hypothesized that because the size of infarct is decreased in pre-menopause female versus post-menopause female and male mice, that changes in microglia morphology post stroke will vary according to sex group. Using skeletal and fractal analysis, we found that ramified morphology is decreased in proximity to injury (endpoints/cell region main effect: F (3,68) = 20.71, p < 0.0001; process length/cell region main effect: F (3,68) = 11.63, p < 0.0001); however there are no differences among sex groups for the endpoints/cell variable (F (2,68) = 0.6, p < 0.55). In addition, fractal dimension decreased in proximity to the ischemic region with significant differences according to sex group (two-way ANOVA: region: F (3,57) = 36.80, p < 0.0001; sex group: F (2,19) = 7.5, p < 0.01). The focus of this study is on the basic discovery of microglia morphological response that can be used to develop treatments that have minimal variability among sex groups.
  • USING RESILIENCE AND INTERVENTION TO UNDERSTAND BPD AND CREATE BETTER TREATMENT METHODS: A LITERATURE REVIEW

    Perkins, Andrew; Rybarcyk, Emily Marie (The University of Arizona., 2019-12)
    Current research on Borderline Personality Disorder (BPD) focuses on risk factors and the effectiveness of dialectical behavior therapy (DBT) as a treatment method. However, little has been researched or written about resilience, intervention, or prevention. This review discusses 11 studies pertaining to resilience, intervention, and DBT. Factors that play into someone being resilient, as well as elements of intervention methods that are related to improvement in symptoms, are also explored. These factors are then compared with the techniques used in DBT to see if there is any overlap. By identifying patterns and finding any overlap, factors that have been shown to have a positive effect on reducing someone’s susceptibility or symptoms can then be implemented into prevention and treatment efforts.
  • CONTENT ANALYSIS OF NEWS ARTICLES ON MEXICAN MIGRATION

    Sallaz, Jeffrey J.; Ross, Taylor Meridian (The University of Arizona., 2019)
    This paper examines the changes in the language used to describe migrants in News articles regarding Mexican migration into the United States. This report analyzes the frequency of words used to describe migrants in 98 online articles from 9 news outlets of varying political leanings from the year 2008-2019. Mexican migration into the United States as well as the tensions surrounding it has been on the rise. Changing sentiments regarding migration are often reflected in the kinds of words used to describe the people migrating across the southern Mexican border. How and where this discourse is happening is important because it matters not just that events are reported accurately, but in a nonbiased manor. While a certain bias even when unintentional is almost unavoidable. This means that the words used to describe certain people and events can give insight into the sentiments of the author as well as potentially the opinions of the average reader. Trends of how news is reported, whether with an active or passive tone, with sympathetic or negative descriptors, and with what key words can indicate shifts in public opinion as well as their correlation to world events that may not be otherwise apparent.
  • THE PERSPECTIVE OF INNOCENCE: A VOICE RECITAL FROM THE POINT OF VIEW OF CHILDREN AND OTHER CHARACTERS WHO DID NOT FULLY UNDERSTAND THEIR SITUATION

    Dauphinais, Kristin; Sova, Ashley Nicole (The University of Arizona., 2019-12)
    This thesis was a culminating recital in accordance with a music degree. It consisted of a one hour solo voice performance that was accompanied by Bonnie Bird on piano. In addition, there were three duets with singers Sebastian Alameda, Brianna Barnhart, and Jacob Walters which required additional planning. For this recital, there are program notes which include background information about the pieces and the structure of the recital, information about the composers, and text and translations of foreign texts. The recital was themed around the innocence of children, and consisted of music in the four themes of children’s songs, dreams, the breaking of innocence, and young love. These themes center around different points of innocence or loss of innocence, and create a cohesive recital reflecting on the desire of humans to relive childhood moments.
  • THE EXPERT AS CHARACTER IN THE WORK OF LE FANU AND LOVECRAFT: SPIRITUALITY, EMPIRICISM, AND RATIONALITY

    Hurh, Paul; Stephens, Joshua Earl (The University of Arizona., 2019-12)
    Sheridan Le Fanu, operating within the Gothic genre, was instrumental in the development of the weird tale. Much of the criticism surrounding his work centers on the social anxiety created during the decline of the Protestant Ascendency in Ireland during the 19th century. This thesis includes the historical context of Le Fanu’s period, as well as a brief section containing an overview of the critical context this thesis seeks to add to. This work argues that Le Fanu’s output, particularly “Green Tea” and Uncle Silas, can be understood when examined from the perspective of the expert as character. It includes a discussion of the interaction between spirituality, empiricism, and rationality in his work. It seeks to explain how the supernatural elements within the narratives can be better understood by inspecting the interchange between the three. It also includes an examination of Le Fanu’s discrete impact on the weird tale genre by exploring the later representation of the expert in the descendent work of H.P. Lovecraft’s The Whisperer in Darkness. The way that the expert functions in the narratives is then an indication of the gradual evolution of the Gothic genre and the emergence and continuation of the weird tale.
  • MUSIC THERAPY FOR PATIENTS WITH DEMENTIA: EVIDENCE INFORMED RECOMMENDATIONS

    Goldsmith, Melissa; Toomey, Nicole (The University of Arizona., 2019-12)
    This thesis will explore the research on implementing music therapy into the care of patients with dementia to decrease anxiety, agitation, and depression. Dementia is a term to describe symptoms secondary to certain medical conditions, such as Alzheimer’s disease, Parkinson’s disease, or a traumatic brain injury. Symptoms of dementia include memory loss, decreased reasoning and judgement, and a decline in language function. Some of the symptoms associated with dementia are a decreased quality of life, depression, anxiety, and agitation. The literature review explores the integrative intervention of music therapy and whether it is beneficial at addressing both symptoms of dementia, and symptoms associated with dementia. Additionally, which forms of music therapy are most effective, and how they can be implemented into the care of patients with dementia successfully are addressed. While the review of the current literature is located in chapter two of this paper, the paper will also identify the best practice recommendations, a proposed plan of implementation, and a proposed evaluation of the implementation plan.
