Description
As a historical event and a much-loved subject of ancient literature, the Trojan War gave birth to many well-known stories, such as The Iliad, which continue to be enjoyed today. Among these is the lesser known work of Geoffrey Chaucer, titled Troilus and Criseyde. It follows the story of Prince Troilus, youngest son of King Priam and a character who is not seen in literature as often as his brothers Hector and Paris. In the 10th year of the Trojan War, Troilus meets the main protagonist, Criseyde, and falls madly in love. Criseyde herself is not in a position to love, but throughout the pages finds herself warming to the prince's favor. Through a beautifully crafted story, Chaucer evokes themes such as loyalty, selfishness, history, physical love versus spiritual love, and the role of women in society. Although it is a lesser known work of Chaucer's, in his day, Troilus and Criseyde was considered his masterpiece. My spring 2016 creative project is a novel retelling of this story entitled In Loving Criseyda. Following the plot of Chaucer's original, In Loving Criseyda is told from the perspective of an additional character: Criseyda's serving maid, Nadia. Nadia serves as the narrator and follows the plot points of the original story, offering her unique perspective on the events. Although Criseyda and Nadia come from opposite ends of society, the two find similarities in their situation and soon become friends. In befriending Criseyda, Nadia's world opens up as she begins to see the world in a new way. The novel becomes a coming of age story for Nadia in the time of the Trojan War, and her journey through love and loss.

Description
The purpose of this project was to identify proteins associated with the migration and invasion of non-transformed MCF10A mammary epithelial cells with ectopically expressed missense mutations in p53. Because of the prevalence of TP53 missense mutations in basal-like and triple-negative breast cancer tumors, understanding the effect of TP53 mutations on the phenotypic expression of human mammary epithelial cells may offer new therapeutic targets for those currently lacking in treatment options. As such, MCF10A mammary epithelial cells ectopically overexpressing structural mutations (G245S, H179R, R175H, Y163C, Y220C, and Y234C) and DNA-binding mutations (R248Q, R248W, R273C, and R273H) in the DNA-binding domain were selected for use in this project. Overexpression of p53 in the mutant cell lines was confirmed by western blot and q-PCR analysis targeting the V5 epitope tag present in the pLenti4 vector used to transduce TP53 into the mutant cell lines. Characterization of the invasion and migration phenotypes resulting from the overexpression of p53 in the mutant cell lines was achieved using transwell invasion and migration assays with Boyden chambers. Statistical analysis showed that three cell lines—DNA-contact mutants R248W and R273C and structural mutant Y220C—were consistently more migratory and invasive and demonstrated a relationship between the migration and invasion properties of the mutant cell lines. Two families of proteins were then explored: those involved in the Epithelial-Mesenchymal Transition (EMT) and matrix metalloproteinases (MMPs). Results of q-PCR and immunofluorescence analysis of epithelial marker E-cadherin and mesenchymal proteins Slug and Vimentin did not show a clear relationship between mRNA and protein expression levels with the migration and invasiveness phenotypes observed in the transwell studies. Results of western blotting, q-PCR, and zymography of MMP-2 and MMP-9 also did not show any consistent results indicating a definite relationship between MMPs and the overall invasiveness of the cells. Finally, two drugs were tested as possible treatments inhibiting invasiveness: ebselen and SBI-183. These drugs were tested on only the most invasive of the MCF10A p53 mutant cell lines (R248W, R273C, and Y220C). Results of invasion assay following 30 μM treatment with ebselen and SBI-183 showed that ebselen does not inhibit invasiveness; SBI-183, however, did inhibit invasiveness in all three cell lines tested. As such, SBI-183 will be an important compound to study in the future as a treatment that could potentially serve to benefit triple-negative or basal-like breast cancer patients who currently lack therapeutic treatment options.

Description
Today's prison industrial complex in the United States often dehumanizes inmates simply because they are criminals. Members of the free society are generally too far removed from the inside of prisons that most people do not see the harsh and cruel conditions for and treatment of prisoners. As a Dance and Justice Studies major at Arizona State University, I was curious about how to intertwine my interests in dance and justice. This paper chronicles my exploration of adding a human rights issue to my dance practice through choreographing a solo dance performance based on Cleve Foster's unusual experience on death row. Research on theories of prison and punishment in American society combined with physical research in the dance studio enabled me to create a solo performance that shed light on the inhumane conditions for and treatment of prison inmates in today's society. Through the process, I found that some elements of my dance practice stayed the same, while others changed. This informed me of what continuously remains important to me, while allowing me to expand my personal dance practice. I ultimately discovered a bridge between my two passions, dance and justice, and learned a meaningful way to convey a contemporary social justice issue to the general public.

In the digital humanities, there is a constant need to turn images and PDF files into plain text to apply analyses such as topic modelling, named entity recognition, and other techniques. However, although there exist different solutions to extract text embedded in PDF files or run OCR on images, they typically require additional training (for example, scholars have to learn how to use the command line) or are difficult to automate without programming skills. The Giles Ecosystem is a distributed system based on Apache Kafka that allows users to upload documents for text and image extraction. The system components are implemented using Java and the Spring Framework and are available under an Open Source license on GitHub (https://github.com/diging/).

Description
This paper examines creative process and performance as a method of research for understanding self-in-context through the lens of my own artistic research for “Dress in Something Plain and Dark,” a project exploring my relationship as a woman to Mennonite religious and cultural identity, spirituality, and dance. Situating my artistic work in relationship to the fields of creative autoethnography, queer and transborder performance art, and somatic dance practice, I discuss the distinctions and commonalities of approach, methods, and practice of artists working in these fields, and the shared challenges of marginalization, translation, and contextualization. In response to these challenges, and the inadequacy of linear, Western, individualistic and mechanistic frameworks to address them, I draw from the ethnographic work of de la Garza, (formerly González, 2000) to seek a “creation-centered” ontological framework that the artist-researcher-performer may use to understand and contextualize their work. I offer the tree as an ontology to understand the organic, emergent nature of creative process, the stages of growth and seasonal cycles, and the structural parts that make up the creative and performative processes, and illustrate this model through a discussion of the growth of “Dress in Something Plain and Dark,” as it has emerged over two cyclical “seasons” of maturation.
Note: This work of creative scholarship is rooted in collaboration between three female artist-scholars: Carly Bates, Raji Ganesan, and Allyson Yoder. Working from a common intersectional, feminist framework, we served as artistic co-directors of each other’s solo pieces and co-producers of Negotiations, in which we share these pieces alongside each other. Negotiations is not a showcase of three individual works, but a conversation among three voices. As collaborators, we have been uncompromising in the pursuit of our own unique inquiries and voices and each of our works of creative scholarship stand alone. However, we believe that all of the parts are best understood in relationship to each other and to the whole. For this reason, we have chosen to cross-reference our thesis documents here, and we encourage readers to view the performance of Negotiations in its entirety.

Description
Background
The purpose of this study is to determine the feasibility of three widely used wearable sensors in research settings for 24 h monitoring of sleep, sedentary, and active behaviors in middle-aged women.
Methods
Participants were 21 inactive, overweight (M Body Mass Index (BMI) = 29.27 ± 7.43) women, 30 to 64 years (M = 45.31 ± 9.67). Women were instructed to wear each sensor on the non-dominant hip (ActiGraph GT3X+), wrist (GENEActiv), or upper arm (BodyMedia SenseWear Mini) for 24 h/day and record daily wake and bed times for one week over the course of three consecutive weeks. Women received feedback about their daily physical activity and sleep behaviors. Feasibility (i.e., acceptability and demand) was measured using surveys, interviews, and wear time.
Results
Women felt the GENEActiv (94.7 %) and SenseWear Mini (90.0 %) were easier to wear and preferred the placement (68.4, 80 % respectively) as compared to the ActiGraph (42.9, 47.6 % respectively). Mean wear time on valid days was similar across sensors (ActiGraph: M = 918.8 ± 115.0 min; GENEActiv: M = 949.3 ± 86.6; SenseWear: M = 928.0 ± 101.8) and well above other studies using wake time only protocols. Informational feedback was the biggest motivator, while appearance, comfort, and inconvenience were the biggest barriers to wearing sensors. Wear time was valid on 93.9 % (ActiGraph), 100 % (GENEActiv), and 95.2 % (SenseWear) of eligible days. 61.9, 95.2, and 71.4 % of participants had seven valid days of data for the ActiGraph, GENEActiv, and SenseWear, respectively.
Conclusion
Twenty-four hour monitoring over seven consecutive days is a feasible approach in middle-aged women. Researchers should consider participant acceptability and demand, in addition to validity and reliability, when choosing a wearable sensor. More research is needed across populations and study designs.

Description
The membrane proximal region (MPR, residues 649–683) and transmembrane domain (TMD, residues 684–705) of the gp41 subunit of HIV-1’s envelope protein are highly conserved and are important in viral mucosal transmission, virus attachment and membrane fusion with target cells. Several structures of the trimeric membrane proximal external region (residues 662–683) of MPR have been reported at the atomic level; however, the atomic structure of the TMD still remains unknown. To elucidate the structure of both MPR and TMD, we expressed the region spanning both domains, MPR-TM (residues 649–705), in Escherichia coli as a fusion protein with maltose binding protein (MBP). MPR-TM was initially fused to the C-terminus of MBP via a 42 aa-long linker containing a TEV protease recognition site (MBP-linker-MPR-TM).
Biophysical characterization indicated that the purified MBP-linker-MPR-TM protein was a monodisperse and stable candidate for crystallization. However, crystals of the MBP-linker-MPR-TM protein could not be obtained in extensive crystallization screens. It is possible that the 42 residue-long linker between MBP and MPR-TM was interfering with crystal formation. To test this hypothesis, the 42 residue-long linker was replaced with three alanine residues. The fusion protein, MBP-AAA-MPR-TM, was similarly purified and characterized. Significantly, both the MBP-linker-MPR-TM and MBP-AAA-MPR-TM proteins strongly interacted with broadly neutralizing monoclonal antibodies 2F5 and 4E10. With epitopes accessible to the broadly neutralizing antibodies, these MBP/MPR-TM recombinant proteins may be in immunologically relevant conformations that mimic a pre-hairpin intermediate of gp41.

Description
Because collective cognition emerges from local signaling among group members, deciphering communication systems is crucial to understanding the underlying mechanisms. Alarm signals are widespread in the social insects and can elicit a variety of behavioral responses to danger, but the functional plasticity of these signals has not been well studied. Here we report an alarm pheromone in the ant Temnothorax rugatulus that elicits two different behaviors depending on context. When an ant was tethered inside an unfamiliar nest site and unable to move freely, she released a pheromone from her mandibular gland that signaled other ants to reject this nest as a potential new home, presumably to avoid potential danger. When the same pheromone was presented near the ants' home nest, they were instead attracted to it, presumably to respond to a threat to the colony. We used coupled gas chromatography/mass spectrometry to identify candidate compounds from the mandibular gland and tested each one in a nest choice bioassay. We found that 2,5-dimethylpyrazine was sufficient to induce rejection of a marked new nest and also to attract ants when released at the home nest. This is the first detailed investigation of chemical communication in the leptothoracine ants. We discuss the possibility that this pheromone's deterrent function can improve an emigrating colony's nest site selection performance.

Description
The number of cancer survivors in the United States is growing rapidly and it is expected to double by 2040. Arizona is nationally ranked with the 14th highest number of survivors, many of which experience a wide range of persisting medical complications that result from the cancer and associated treatment. Consequently, there is an increased need for services tailored to the health and wellness of survivors. Studies have shown that exercise rehabilitation is effective in improving the physical and mental health of this patient population. This project aimed to investigate the status of medically-based exercise rehabilitation for cancer survivors in Arizona. It focused on services offered by cancer treatment centers and cardiac rehabilitation clinics, with cardiac rehabilitation providing a possible delivery method for future cancer exercise rehabilitation. A directory of resources was compiled based on responses to structured telephone interviews with the cancer treatment centers (n=32) and cardiac rehabilitation clinics (n=34) within the state. The directory will serve as a resource for both patients and clinicians by identifying statewide related services that are available at the medical institutions and within the community. Results showed that 42.9% and 39.4% of the cancer treatment centers and cardiac rehabilitation clinics, respectively, offered exercise related services for cancer survivors. 78.6% of cancer centers stated that they refer cancer survivors to physical therapy, while only 35.7% refer survivors to community-based programs. Only 2 cardiac rehabilitation clinics, or 6%, offered preventative cardiology exercise consultations to cancer survivors. In conclusion, rehabilitative exercise resources for cancer survivors in Arizona were limited. Additional cancer rehabilitation efficacy studies are needed to further clarify evidence-based practice guidelines and provide direction for optimal methods of healthcare delivery. It is recommended that this directory remains current with routine updates in an effort to increase patient accessibility to care.

Description
The purpose of this thesis creative project was to create an educational video to present research findings on the increasingly important issue of human biospecimen preanalytic variables. When a human biospecimen, such as blood, urine, or tissue, is removed from the body, it is subjected to a plethora of variables that are not recorded or regulated in a vast majority of cases. Frequently, these samples arrive at the research or pathology lab with an unknown history, then undergo analysis for translational research purposes, or to guide clinical management decisions. Thus, compromised specimen quality caused by preanalytic variables has substantial, and potentially devastating, downstream effects. To identify the preanalytic variables with the greatest impact on blood and tissue specimen quality, 45 articles were gathered using PubMed and Google Scholar databases and cited. Based on the articles, the top five variables with the most detrimental effects were identified for both blood and tissue samples. Multiple sets of parameters ensuring specimen fitness were compared for each of the five variables for each specimen type. Then, specific parameters guaranteeing the fitness of the greatest number of analytes were verified. To present the research findings in greater detail, a paper was written that focused on identifying the top variables and key parameters to ensure analyte fitness. To present the overall issue in an easy-to-digest format, a storyboard and script were created as a guideline for a final video project. Ultimately, two alternate versions of the video were created to pertain to the audience of choice (one version for patients, one version for professionals). It is the hope that these videos will be used as educational tools to continue efforts to standardize and enforce human biospecimen preanalytic variable parameters. This is a necessary step to improve the accuracy of our biomedical research data and the healthcare of patients worldwide.
