This thesis paper examines the effects of increased standing and light physical activity in the workplace on postprandial glucose. Sedentary behavior is detrimental to our health, affecting metabolic risk factors. An easy way to implement change is by decreasing sedentary time in workplaces where sitting is common, such as office workspaces. To consider how postprandial glucose is affected by decreasing sedentary time, participants ate a standardized meal for lunch and were asked to decrease their sitting time by replacing it with standing and light physical activity.

Oral Microbiome Analysis Reveals Potential for Streamlining Diagnosis of Rheumatoid Arthritis

Description

Rheumatoid Arthritis (RA) is an autoimmune disorder where the body mistakenly attacks healthy joints. This in turn causes inflammation resulting in pain and swelling. It is very important to get RA accurately diagnosed and treated as early as possible. Similarly,

Rheumatoid Arthritis (RA) is an autoimmune disorder where the body mistakenly attacks healthy joints. This in turn causes inflammation resulting in pain and swelling. It is very important to get RA accurately diagnosed and treated as early as possible. Similarly, with any disease: the longer it is left untreated, the more damage it can cause. RA can cause irreversible joint damage leading to disability. The purpose of this study is to determine if oral microbiome can be used as an additional criterion to aid in diagnosing RA. Several oral microbes have already been identified as biomarkers for RA in saliva. In this study, 10 participants were recruited: 6 diagnosed with RA and 4 Healthy as a control. Two subgroups of RA were done within this study; those diagnose with a positive Rheumatoid Factor (RF) and those diagnose with a negative RF. These subgroups were then compared in order to determine the validity of using certain microbes as biomarkers for RA even when different diagnostic criteria were met. The microbe Parahaemolyticus had the largest measure of effect, showing the greatest potential for statistically significant results with a larger sample size. If we can work narrow to down specific microbes to be undoubtedly higher in abundance with already diagnosed RA patients when comparing to healthy participants, this will be a gamechanger. Not only could we give a higher sense of confidence with the diagnosis of RA, but this could streamline RA diagnosis.

Kinematics of Soccer Players During a 5-10-5 Agility Drill

Description

Purpose: The purpose of this study was to observe similarities and differences within soccer players during a 5-10-5 agility drill between the first and second change of direction. Overall body mechanics and center of mass position relative to the feet

Purpose: The purpose of this study was to observe similarities and differences within soccer players during a 5-10-5 agility drill between the first and second change of direction. Overall body mechanics and center of mass position relative to the feet were assessed within players. Methods: A total of 6 soccer players participated in the study. Each player ran through the 5-10-5 agility drill 10 times. All trials were video recorded and oriented to include the whole drill. Data was assessed using the program Kinovea (open-source) for 5 out of the 6 players. One player was excluded due to not meeting the inclusion criteria. The metrics assessed were total time to complete the task, the change of direction time, the time it took for the lag leg to stop moving laterally to the planting of the lead leg, and the leg angle. All tasks, except for total task time, were assessed for both the first and second change of direction. An individual analysis was performed for each player in order to obtain observational differences between the first and second change of direction for players. Results: The total task time determined the order of the players, thus the fastest player became player 1 and the slowest player 5. Players 1, 2, 4, and 5 were all found to have a statistical significance in change of direction time. When statistically significant the change of direction time was faster for the second change of direction. The slower players, player 4 and 5, had a statistically significant difference in leg angle, with the leg angle being larger for the first change of direction. Player 3 had no significant differences between any of the metrics. When looking closer at the faster players an observable difference in center of mass position relative to the feet was observed. The second change of direction showed the center of mass being positioned further anterior to the feet, and better mechanics were used to slow down and prepare to change direction. Discussion: The center of mass position relative to the feet could likely explain why the second change of direction was faster for 4 out of the 5 players. With the current information from the present study it could be adapted to help coaches instruct players to incorporate better mechanics into their change of direction tasks, and possibly improve their agility. This study could be improved by using multiple camera angles, high definition cameras, body markers, and force plates. By using these tools information could be obtained about variables that impact change of direction tasks but were not measured in the current study.

Does chronic unpredictable restraint produce dendritic retraction in long-shaft CA3 hippocampal neurons?

Description

Major Depressive Disorder (MDD) is a widespread mood disorder that affects more than 300 million people worldwide and yet, high relapse rates persist. This current study aimed to use an animal model for depression, unpredictable intermittent restraint (UIR), to investigate

Major Depressive Disorder (MDD) is a widespread mood disorder that affects more than 300 million people worldwide and yet, high relapse rates persist. This current study aimed to use an animal model for depression, unpredictable intermittent restraint (UIR), to investigate changes in a subset of neurons within the hippocampus, a region of high susceptibility in MDD. Adult male and female Sprague-Dawley rats were randomly assigned to four treatment groups based on sex (n = 48, n = 12/group). Half of the rats underwent UIR that involved restraint with orbital shaking (30 min or 1 h) for 2-6 consecutive days, followed by one or two days of no stressors; the other half of the rats were undisturbed (CON). UIR rats were stressed for 28 days (21 days of actual stressors) before behavioral testing began with UIR continuing between testing days for nearly 70 days. Rats were then euthanized between 9 and 11 days after the last UIR session. Brains were processed for Golgi stain and long-shaft (LS) neurons within the hippocampal CA3a and CA3b regions were quantified for dendritic complexity using a Camera Lucida attachment. Our findings failed to support our hypothesis that UIR would produce apical dendritic retraction in CA3 hippocampal LS neurons in both males and females. Given that UIR failed to produce CA3 apical dendritic retraction in males, which is commonly observed in the literature, we discuss several reasons for these findings including, time from the end of UIR to when brains were sampled, and the effects of repeated cognitive testing. Given our published findings that UIR impaired spatial ability in males, but not females, we believe that UIR holds validity as a chronic stress paradigm, as UIR attenuated body weight gain in both males and females and produced reductions in thymus gland weight in UIR males. These findings corroborate UIR as an effective stressor in males and warrant further research into the timing of UIR-induced changes in hippocampal CA3 apical dendritic morphology.

Rainbow Rhetoric: LGBTQ+ Media Discourse and Implications

Description

Aside from uplifting and tearing down the mood of a young LGBTQ+ kid, journalistic media has the potential to alter the way audiences understand and react to individuals of the LGBTQ+ community. Looking at the rhetorical approaches, frameworks, and expanded

Aside from uplifting and tearing down the mood of a young LGBTQ+ kid, journalistic media has the potential to alter the way audiences understand and react to individuals of the LGBTQ+ community. Looking at the rhetorical approaches, frameworks, and expanded narratives of news sources, this project engages with the concepts of same-sex marriage, lifestyles, bans, and children in education in order to attain an understanding of what media messages are being shared, how they are being communicated, and what the implications of such rhetoric are. Summary of the findings:
• Same-sex marriage as the win that cannot be repeated.
Infamously known as the central legal battle for the LGBTQ+ community, same-sex marriage finds itself in many political speeches, campaigns, and social commentaries. Interestingly, after being legalized through a Supreme Court decision in the United States, Same-Sex Marriage finds itself framed as the social inevitability that should not be repeated in politics or any legal shift. In other words, “the gays have won this battle, but not the war.”
• There are risks around the “LGBTQ+ lifestyle” and its careful catering to an elite minority and the mediation through bans.
The risks of the LGBTQ+ “lifestyle” date back far, with many connotations being attached to being LGBTQ+ (AIDS epidemics, etc.). In modern journalism, many media outlets portray LGBTQ+ individuals to be a tiny minority (.001% according to some) that demands the whole society to adhere to their requests. This framework portrays the LGBTQ+ community as oppressors and obsessed advocates that can never “seem to get enough” (ex: more than just marriage). The bans are framed as the neutralizing factor to the catering.
• LGBTQ+ children and topics in academic and social spaces are the extreme degree.
When it comes to LGBTQ+ issues and conversations as they revolve around children, media outlets have some of the most passionate opinions about them. Often portrayed as “the line that shouldn’t be crossed,” LGBTQ+ issues, as they find themselves in schools and other spaces, are thus portrayed as bearable to a certain degree, never completely. Claims of indoctrination are also presented prominently even when institutional efforts are to protect LGBTQ+ kids.

Can You See Me?: Stories to Fight Erasure

Description

There has been a recent push for queer fiction, especially in the young adult genre, whose focus is gay and lesbian relationships. This growth is much needed in terms of visibility and the furthering of acceptance, but there are still

There has been a recent push for queer fiction, especially in the young adult genre, whose focus is gay and lesbian relationships. This growth is much needed in terms of visibility and the furthering of acceptance, but there are still subjects within the LGBTQ+ community that need to be addressed, including bisexual, asexual, and non-binary erasure. There are many people who claim that these identities do not exist, are labels used as a stepping stone on one's journey to discovering that they are homosexual, or are invented excuses for overtly promiscuous or prudish behavior. The existence of negative stereotypes, particularly those of non-binary individuals, is largely due to a lack of visibility and respectful representation within media and popular culture. However, there is still a dearth of non-binary content in popular literature outside of young adult fiction. Can You See Me? aims to fill the gap in bisexual, asexual, and non-binary representation in adult literature. Each of the four stories that make up this collection deals with an aspect of gender and/or sexuality that has been erased, ignored, or denied visibility in American popular culture. The first story, "We'll Grow Lemon Trees," examines bisexual erasure through the lens of sociolinguistics. A bisexual Romanian woman emigrates to Los Angeles in 1989 and must navigate a new culture, learn new languages, and try to move on from her past life under a dictatorship where speaking up could mean imprisonment or death. The second story "Up, Down, All Around," is about a young genderqueer child and their parents dealing with microaggressions, examining gender norms, and exploring personal identity through imaginary scenarios, each involving an encounter with an unknown entity and a colander. The third story, "Aces High," follows two asexual characters from the day they're born to when they are 28 years old, as they find themselves in pop culture. The two endure identity crises, gender discrimination, erasure, individual obsessions, and prejudice as they learn to accept themselves and embrace who they are. In the fourth and final story, "Mile Marker 72," a gay Mexican man must hide in plain sight as he deals with the death of his partner and coming out to his best friend, whose brother is his partner's murderer.

This creative project centers on creating evaluative writing about film, in the form of a film review blog. Preliminary writing was done, in which the distinction was made between critical film writing and movie reviewing, as well as an analysis of how film critics have honed in their criticism and what makes their content effective for their audience. The rest of the writing for this project consists of a total of 15 reviews for 15 different movies released in 2017 and 2018. In these reviews, there is a brief introduction of the plot and context in which the film is made, followed by an evaluative analysis of what made the film effective or ineffective in achieving its artistic goals. The reviews involve an amalgamation of the content and topics taught in the Film and Media Studies program at Arizona State University, from screenwriting to cinematography. This process of writing reviews and being edited by the Director and Second Reader allows for the opportunity to find a unique writing voice and create content that is accessible for the wide audience that would be reading the work. All of the writing completed for this project (except for the "My Favorite Film Critics" piece) is compiled together in a WordPress blog, in an easily readable and accessible format. The blog itself serves as a way to reach the desired audience, as well as entice them to engage with the writing and the films being written about. This includes providing images and trailers for each respective film, to add a visual component to the writing. The final product is a unique way to engage with the content taught in the Film and Media Studies program, while simultaneously building a portfolio of writing that will be expanded upon and continued in the future.

"After Papa Died": A Mexican-American Autobiography Annotated and Edited by Shea Van Slyke

Description

Zoraida Ladrón de Guevarra was born in 1936 in Coyula, Mexico, a small village in the state of Oaxaca. Her father’s passing required Zoraida to find a job at age fourteen to support her family. Her story, a 200-page memoir

Zoraida Ladrón de Guevarra was born in 1936 in Coyula, Mexico, a small village in the state of Oaxaca. Her father’s passing required Zoraida to find a job at age fourteen to support her family. Her story, a 200-page memoir entitled “After Papa Died,” follows Zoraida’s time as a servant and eventual nanny in Veracruz. Flashing back to memories of her hometown and the people living in it, the story ends before she enters America first as a visitor in 1954, and later on a working Visa in 1957—the first woman in her village to leave to the United States. Hers is a story relevant today, evident with the paradoxes explored between poverty and riches, patriarchy and matriarchy, freedom and captivity. Assimilation impacts the reading of this memoir, as Zoraida began writing the memoir in her 80s (around fifty years after gaining American citizenship). This detailed family history is about the nature of memory, community, and in particular, the experience of being an immigrant. This thesis project centers on this text and includes three components: an edited memoir, informational interviews, and an introduction. Beginning as a diary steeped in the tradition of oral history, the memoir required a “translation” into a written form; chapters and chronological continuity helped with organization. Topics of interest from the story, such as identity, domestic violence, and religion, are further explored in a series of interviews with Zoraida. The inclusion of an introduction to the text contextualizes the stories documented in the memoir with supplemental information. The contents of the project are housed on a website: alongwaybabyproject.net.

This project consists of five short stories in varying genres, all leaning towards the fantastic. "Wood Devils" (Honorable Mention in the 2018 Swarthout Awards in Writing) attempts to explore the absurdity and pain in long-running family conflicts, as well as the sense of isolation that comes from living in hard-to-reach places. "The Green Man's Daughter" investigates the boundary between the fantastical and the everyday by using the Other as a viewpoint, and underscores the importance of speaking out in a confusing and sometimes frightening world. "Maleficis ex Machina" attempts to look at community violence, mishandled technology, and intergenerational conflict by taking the collision between the fantastic and suburban to an even greater degree than the previous piece. "Probation" sits at a crossroads between bureaucracy and corporatization, and looks at the benefits of finding a middle ground between Heaven and Hell. "For a Crown" dramatizes the only partially-successful attempt in history at stealing the crown jewels from the Tower of London, and Charles II's inexplicable pardoning of the thief. Although the stories do not intersect (shared names and an abundance of cats notwithstanding), they all focus on the barrier between the mundane and the extraordinary. Just how porous that boundary may be is, as always, uncertain.

Occurrence of a Pathogenic Fungus in Captive Arizona Amphibians

Description

Amphibians have been experiencing a worldwide decline that is in part caused by an infectious disease, chytridiomycosis, specific to frogs and salamanders. Globally many species have declined or gone extinct because of the pathogenic fungus Batrachochytrium dendrobatidis, also known as

Amphibians have been experiencing a worldwide decline that is in part caused by an infectious disease, chytridiomycosis, specific to frogs and salamanders. Globally many species have declined or gone extinct because of the pathogenic fungus Batrachochytrium dendrobatidis, also known as the amphibian chytrid or Bd. By the time Bd was discovered it was too late to stop the spread and it has now been found on almost every continent. The trade of captive amphibians, used as pets, bait, and educational animals provides an opportunity to spread Bd. Because some amphibians can carry Bd without experiencing symptoms, it is possible for even healthy looking amphibians to spread the amphibian chytrid if they are moved from one location to another. Recently, a new species Batrachochytrium salamandrivorans (Bsal) was found on salamanders. Bsal was identified before it reached the United States, prompting concern regarding its spread and a call for regulation regarding the trade of captive amphibians. There are some regulations in place controlling the trade of amphibians, but they are insufficient to stop the spread of amphibian chytrid in captive populations. A 2016 law prohibits the importation of 201 salamander species. However, there is no central organization to sample or certify if amphibians are free from Bd or Bsal. Although some stores say they test for these pathogens the tests are unregulated and not reported to any central body. If the captive amphibian trade is to go disease free, there would need to be a significant push to coordinate testing efforts. To estimate Bd's prevalence in Arizona captive amphibian populations, I contacted pet stores, bait stores, and sanctuary or educational organizations to ask if I could sample their amphibian collections. My research built on the 2008 work of Angela Picco, who sampled for the amphibian chytrid in Arizona bait shops. I found that amphibian owners were often hesitant and unwilling to participate in this research opportunity. There are multiple reasons for this hesitancy including a fear of increased regulation, the potential for reporting to a government agency (USDA), or the eventual cessation of amphibian trade. The lack of willing participants suggests there may be difficulties in coordinating future sampling efforts for Bd and Bsal.
