title: The Trickster Methodology: Describing the creative process of fiction writers
Creators: name: East, Tara

Subjects: classificationCode: 360201
subject: Creative writing (incl. scriptwriting)

description: This thesis focuses on a creative writing research investigation that examines creative practice and how it led to a written product (a novel) as well as an exegesis that offers a unique methodology for describing the creative process. The trickster methodology combines elements of practice-led research with trickster qualities (slippery, subversive, disruptive, unstable, creative, destructive, ambiguous) by identifying four qualities that are particularly relevant to creative writers: shapeshifting, play, chance, and order. The theoretical frameworks that underpin this methodology include Mikhail Bakhtin’s concept of the carnivalesque and Sara Ahmed’s notion of willfulness. The trickster methodology is distinct from existing research frameworks and models of creativity as it reflects the fluidity of the writing process and the ways in which writers embody that fluidity. In this way, it extends upon our current understanding of practice-led research, offering a model of clearly defined traits that remain malleable and flexible enough for individual use while providing a way to describe the creative process that leads to a written product. This research investigation draws upon a series of interviews conducted with career authors, which were mapped against scholarly materials, as well as my own creative practice, to identify trickster traits within the creative processes of fiction writers, and to identify how creative practitioners can intentionally engage with these qualities as a way to challenge themselves to do or make differently. The creative artefact is the product of this methodology. The creative work and the trickster methodology were developed simultaneously. Insights gained while writing shaped the methodology, and my figurative and metaphorical understanding of the trickster figure informed the narrative. The trickster methodology challenged and changed my creative process, resulting in an innovative novel, which I could not have written prior to this investigation. Together, the two works explore through critical and creative voices and strategies a fresh way to approach and articulate the creative process. This dissertation is a multi-bodied and multivocal trickster whose liminal perspective supports practitioners in exploring the range of possibilities within their creative work while also accounting for the continuing and evolving process that is creativity.

description: Background: Australian harm reduction services are provided via a mix of modalities, including fixed-site needle and syringe programmes (NSP) and syringe-dispensing machines (SDMs). SDMs are cost-effective and provide 24-h anonymous access to needles/syringes, often to underserved geographic areas, and can attract clientele who may choose not to use NSPs. The introduction of COVID-19 control measures saw disruptions and adaptations to the provision of harm reduction services. It is possible that SDMs filled the gap in otherwise disrupted harm reduction services in Melbourne. In this paper, we use data from four SDMs and an NSP to explore changes to harm reduction usage during periods of COVID-19 lockdowns in Melbourne, Australia, in 2020. Methods: Our data span September 2017–December 2020. We analysed daily counts of SDM use and monthly counts of NSP use, according to unique presentations to both. Auto-regressive integrated moving average (ARIMA) time-series models were fitted to the data with the effects of lockdowns estimated via a step function. Results: Across the study period, we estimated 85,851 SDM presentations and 29,051 NSP presentations. Usage across both the SDMs and the NSP declined during the COVID-19 lockdowns, but only the decline in SDM usage was significant in ARIMA analysis. Conclusions: The slight, but significant decline in SDM use suggests barriers to access, though this may have been mitigated by SDM users acquiring needles/syringes from other sources. The decline, however, may be a concern if it led to lowered needle/syringe coverage and a subsequent increase in injecting risk. Further work is needed to properly explore potential changes in preference for needle/syringe acquisition site and associated barriers. Importantly, this work adds to the body of literature around the impacts of COVID-19 on harm reduction provision and potential areas of improvement.
Electrosynthesis of Designer Electrocatalytic High-Entropy Nanoparticles & Studying the Effect of Polishing to Develop Designer Polishing Nanoparticles

description: Electrodes are valuable instruments in a wide variety of research fields such as chemistry, biology, and psychology. On a microscopic scale, the geometry of the electrode influences the kinetics of the reaction taking place. Polishing is a universal technique to obtain an electrode surface free of defects thereby making the in-depth study of the effects of polishing on the electrode surface an important understanding. The use of sandpaper and alumina slurry is a common method to mechanically polish electrodes of a variety of sizes. However, advances in technology have allowed for the development and use of ultramicro- and nano-electrodes where the dimensions are on the same order of magnitude as the polishing method. Other techniques to polish an electrode such as electrochemical cycling of the electrode surface, chemical treatment, and FIB milling exist for electrodes of a variety of sizes; however, these techniques are often restrictive and complex. Additionally, some degree of mechanical polishing may be necessary in conjunction with alternate methods. Here, we present an electrochemical analysis of the effect of polishing particle size on the electrode surface to observe a mathematical relationship between particle size and expected electrode roughness factor and the existence of a linear region of efficient polishing. By using cyclic voltammetry to observe the steady-state current of a platinum microelectrode (r=5 µm) of the reduction of ferrocene methanol and the double-layer capacitance of a non-faradaic region, we calculate the change in roughness factor as a function of polishing particle size. Furthermore, the study of using fullerene (r=550 pm) as an alternative mechanical polishing method is presented.

description: We describe a conjectural construction (in the spirit of Hilbert's 12th problem) of units in abelian extensions of certain base fields which are neither totally real nor CM. These base fields are quadratic extensions with exactly one complex place of a totally real number field F, and are referred to as Almost Totally real (ATR) extensions. Our construction involves certain null-homologous topological cycles on the Hilbert modular variety attached to F. The special units are the images of these cycles under a map defined by integration of weight two Eisenstein series on GL_2(F). This map is formally analogous to the higher Abel-Jacobi maps that arise in the theory of algebraic cycles. We show that our conjecture is compatible with Stark's conjecture for ATR extensions; it is, however, a genuine strengthening of Stark's conjecture in this context since it gives an analytic formula for the arguments of the Stark units and not just for their absolute values. The last section provides numerical evidences for our conjecture.

description: Ekbom syndrome or delusional parasitosis is a psychotic disorder characterized by the delusion belief that the skin is infested by parasites, such as insect or worms, that move on or in it. This belief is accompanied by tactile hallucinations and pruritus, which is intense itching that causes the desire to scratch. It leads to people who suffer from this syndrome have skin lesions caused by compulsive scratching, and sometimes they bring samples of what they think are parasites but are actually remains of skin or hair.Treatment often includes antipsychotic drugs, with the goal of reducing hallucinations, and improving patients' quality of life.
Examining Effects of Membrane Tension on Exocytic Mode and Neuronal Development
Creators: name: Wolfgram, Emily
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Exocytosis, a process where intracellular vesicles fuse and secrete lumenal cargo, is fundamental to eukaryotes. Exocytosis requires sufficient energy present in order for SNARE proteins on the vesicle and plasma membrane pull the membrane apart to form a fusion pore. Two modes of exocytosis are described at the synapse of mature neurons: full vesicle fusion (FVF) and kiss-n-run (KNR). During FVF, the entire vesicle incorporates into the plasma membrane. During KNR, the fusion pore only opens transiently, and the vesicle membrane is not added to the plasma membrane. Membrane tension can contribute to the amount of energy required for FVF and KNR events to occur. In developing neurons FVF is critical for growth, and we presume that more membrane tension is also necessary to aid in the energy requirement for FVF events. We hypothesize that the rate and mode of exocytosis is sensitive to local membrane tension at the site of exocytosis. To test this hypothesis, we alter membrane composition as a proxy for membrane tension by using Methyl-β- cyclodextrin (MβCD) and propylene glycol/vegetable glycerin (PG/VG). In looking at immediate exposure to these compounds, we analyze the effect of treatment on the rate and mode of exocytosis using live-cell imaging. To examine how this alters axon length and other parameters of neuronal morphology, we use immunocytochemistry in chronically treated neurons. Our studies suggest that altering membrane tension affects the frequency and mode of exocytosis. Understanding neuronal morphology and plasma membrane composition are critical for future studies on neuron interactions in the brain.

description: Predicting the popularity of items in rating networks is an interesting but challenging problem. This is especially so when an item has first appeared and has received very few ratings. In this paper, we propose a novel approach to predicting the future popularity of new items in rating networks, defining a new bipartite clustering coefficient to predict the popularity of movies and stories in the MovieLens and Digg networks respectively. We show that the clustering behaviour of the first user who rates a new item gives insight into the future popularity of that item. Our method predicts, with a success rate of over 65% for the MovieLens network and over 50% for the Digg network, the future popularity of an item. This is a major improvement on current results.

Reciprocal Regulation of Microtubule Affinity-Regulating Kinase 2 and CREB-Binding Protein
Creators: name: Tabassum, Zarin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Tau is a neuronal microtubule-binding protein that forms characteristic neurofibrillary tangles (NFT), upon hyperphosphorylation, hyperacetylation, and aggregation, which are hallmark biomarkers for Alzheimer’s disease (AD). The pathophysiological conversion of tau still remains unclear, but the regulation and synergy of tau’s post-translational modifications (PTMs) by certain enzymes can be monitored. This study investigates the interactions between two enzymes involved in regulating tau’s PTMs: the microtubule affinity-regulating kinase (MARK2) and the acetyltransferase CREB-binding protein (CBP). We performed a series of biochemical analyses, which uncovered that CBP-mediated acetylation was increased in the absence of MARK2, indicating a possible negative feedback loop, in which MARK2 is phosphorylating and thereby inhibiting CBP. Further investigation of the protein-protein interactions revealed increased acetylation of an inactive MARK2 mutant compared to wild-type MARK2 in the presence of CBP. This finding supports the idea that active MARK2 may be involved in decreasing CBP-mediated acetylation. Although the exact mechanism of this interaction and its role in tau dysfunction have yet to be determined, we have uncovered a new signaling pathway in which two enzymes may regulate each other.

description: The main objective of this study was to measure the nutritional status of iron and vitamin D in varsity female athletes from the University of Ottawa and the possible relationship with their dietary patterns (mixed diet or plant-based diet). Among 63 athletes interested in participating, 17 completed the study. Nutritional intakes were assessed during sports season using two 24-hour recalls with the self-administered dietary assessment tool (ASA24). A blood sample was taken to measure indicators of iron and vitamin D status. The results revealed that 5% of the athletes suffered from vitamin D deficiency and as much as 47% had suboptimal vitamin D levels. No athletes suffered from iron deficiency anemia (IDA), but 26% had iron deficiency (ID). The vitamin D intake for 94% of athletes was below the estimated average requirements (EAR) and the use of supplements helped athletes attain the EAR. In contrast, 94% of athletes were able to meet the EAR for iron and the use of supplements caused athletes to exceed upper limits (UL). Lastly, due to the small number of plant-based athletes recruited, it was not possible to establish any relationships with this dietary pattern.

Taking into account that not all the autonomous communities have these consultations implemented in the health system, we consider that this service is essential to implement and develop it in the rest of the communities, to offer the patient better care primary.
Internalised Weight Stigma Mediates Relationships Between Perceived Weight Stigma and Psychosocial Correlates in Individuals Seeking Bariatric Surgery: a Cross-sectional Study

description: Purpose: Research suggests that internalised weight stigma may explain the relationship between perceived weight stigma and adverse psychological correlates (e.g. depression, disordered eating, body image disturbances). However, few studies have assessed this mechanism in individuals seeking bariatric surgery, even though depression and disordered eating are more common in this group than the general population. Materials and Methods: We used data from a cross-sectional study with individuals seeking bariatric surgery (n = 217; 73.6% female) from Melbourne, Australia. Participants (Mage = 44.1 years, SD = 11.9; MBMI = 43.1, SD = 7.9) completed a battery of self-report measures on weight stigma and biopsychosocial variables, prior to their procedures. Bias-corrected bootstrapped mediations were used to test the mediating role of internalised weight stigma. Significance thresholds were statistically corrected to reduce the risk of Type I error due to the large number of mediation tests conducted. Results: Controlling for BMI, internalised weight stigma mediated the relationship between perceived weight stigma and psychological quality of life, symptoms of depression and anxiety, stress, adverse coping behaviours, self-esteem, exercise avoidance, some disordered eating measures and body image subscales, but not physical quality of life or pain. Conclusion: Although the findings are cross-sectional, they are mostly consistent with previous research in other cohorts and provide partial support for theoretical models of weight stigma. Interventions addressing internalised weight stigma may be a useful tool for clinicians to reduce the negative correlates associated with weight stigma.

Targeted Delivery of Antioxidant Nanoparticles to Inhibit Restenosis
Creators: name: Maydew, Rachel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Cardiovascular disease is the leading cause of death globally, often resulting from the development of atherosclerosis. Common surgical interventions, such as balloon angioplasty, repeatedly fail due to the re-narrowing of an artery over time, a process called restenosis. Neointimal hyperplasia, the proliferation and migration of cells that leads to restenosis, is driven by reactive oxygen species (ROS). In natural response to injury, macrophages target inflammation in the vasculature. This response provides a strategy for targeted delivery of therapeutics, but it is unknown whether macrophages can deliver antioxidant enzymes to sites of arterial injury. We hypothesize that macrophages can be loaded with antioxidant enzyme nanoparticles (NPs) to deliver enzymatically active catalase (CAT) or superoxide dismutase (SOD) in order to decrease ROS and hence, inhibit neointimal hyperplasia. Using dynamic light scattering (DLS) and nanoparticle tracking analysis (NTA), catalase NPs and SOD NPs size and dispersity were characterized. Encapsulated enzymes were enzymatically active and stable for 7 days, indicating that nanoparticles do not inhibit enzymatic activity. Macrophage uptake of enzyme-loaded NPs was assessed using fluorescence microscopy. Uptake by murine macrophages (RAW 264.7) peaked at 2 hours with macrophages engulfing more fluorescently-labeled enzyme-loaded NPs than free enzyme. Using macrophages with antioxidant enzyme-loaded nanoparticles is a viable approach to deliver active catalase or SOD, resulting in a targeted delivery system for sites of restenosis. This strategy would present a great advantage to the medical world, as preparation of targeted drug therapy could be executed ex vivo with the potential to be implemented back into the patient.

description: In light of new results, the one-dimensional mean-field dynamo model of Brandenburg & Kapyla (2007) with dynamical quenching and a nonlocal Babcock-Leighton alpha effect is re-examined for the solar dynamo. We extend the one-dimensional model to include the effects of turbulent downward pumping (Kitchatinov & Olemskoy 2011), and to combine dynamical quenching with shear. We use both the conventional dynamical quenching model of Kleeorin & Ruzmaikin (1982) and the alternate one of Hubbard & Brandenburg (2011), and confirm that with varying levels of non-locality in the alpha effect, and possibly shear as well, the saturation field strength can be independent of the magnetic Reynolds number.

Ο λόγος ο οποίος την καθιστά τόσο βασική διαδικασία είναι ότι η ποικιλία των προϊόντων της έχουν χρήσεις που εκτείνονται από τη λειτουργία και την αναβάθμιση μηχανημάτων μίας παραγωγής έως και στους επεξεργαστές που χρησιμοποιούνται εντός των ηλεκτρονικών υπολογιστών. Η διαδικασία αυτή έχει πολλές υποκατηγορίες που οι διαφορές τους κυμαίνονται από τον τρόπο που γίνεται η μορφοποίηση του μετάλλου έως και τη θερμοκρασία που λαμβάνει μέρος κατά τη μορφοποίηση ή και την έκταση της πραγματοποιούμενης παραμόρφωσης. Κύριος στόχος αυτής της διπλωματικής εργασίας είναι η προσομοίωση της διαδικασίας μορφοποίησης σωλήνων από ράβδους μεταλλεύματος, η οποία είναι μία διαδικασία ψυχρής έλασης.

description: The metal forming process has established itself as one of the fundamental processes in both heavy machinery component production and the manufacturing of small everyday use devices. The reason it is such a crucial process is that the range of its products spans from enhancing and upgrading production machinery to processors used in electronic computers. This process has several subcategories, differing in how the metal is shaped, the temperature at which it occurs, or the extent of deformation taking place. The primary goal of this thesis is to simulate the cold forming process of tubes from metal rods. This specific process involves reducing the cross-section of a metal rod through the use of a die without increasing its temperature. The study of this process within a simulation environment will be conducted using finite elements and the theory of plasticity. It will be examined in two stages, initially in a static loading environment and subsequently in a semi-static loading environment. The results of this study will be used to optimize the final product of the process and, at the same time, reduce energy costs. Additionally, it will enable the prediction of potential failures attributed to fractures, folds, and other imperfections.

description: Graphical models are widely used to study biological networks. Interventions on network nodes are an important feature of many experimental designs for the study of biological networks. In this paper we put forward a causal variant of dynamic Bayesian networks (DBNs) for the purpose of modeling time-course data with interventions. The models inherit the simplicity and computational efficiency of DBNs but allow interventional data to be integrated into network inference. We show empirical results, on both simulated and experimental data, that demonstrate the need to appropriately handle interventions when interventions form part of the design.

description: We show that several diffusion-based approximations (classical diffusion or SP1, SP2, SP3) to the linear Boltzmann equation can (for an infinite, homogeneous medium) be represented exactly by a non-classical transport equation. As a consequence, we indicate a method to solve diffusion-based approximations to the Boltzmann equation via Monte Carlo, with only statistical errors - no truncation errors.

Mutagenic Compounds as Broad Spectrum Antivirals
Creators: name: Hill, Collin S.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

Subjects: Antiviral nucleosides

description: Most RNA viruses utilize RNA-dependent RNA polymerases for viral genome replication and synthesis of mRNAs, making them prime targets for mutagenic compounds to be utilized as broad-spectrum antivirals. Primer ID with next-generation sequencing (NGS) allows for accurate and deep characterization of viral populations, which provides for the ideal tool for screening mutagenic compounds and their effects on RNA viruses. In this study, we used this approach to study three potential mutagenic compounds (N4-beta-hydrocytidine, Favipiravir, and Ribavirin) on a panel of RNA viruses, including MERS coronavirus (MERS-CoV), Zika virus (ZIKV), and La Crosse virus (LACV). We hypothesize that these compounds exhibit antiviral effects by inducing lethal mutations in the viral genomes. We used a cell culture model where we grew the viruses in cell culture in the presence and absence of drugs, determined viral titers using plaque assays, and sequenced viruses at different time points to compare sequence differences by using primer ID and NGS. Using this data from the in vitro experiments, we developed a model to predict the percentage of defective viral genomes after treatment with mutagenic compounds. We also used an in vivo mice-MERS coronavirus model to study the antiviral effects and short-term toxicity of NHC. To study the long term toxicity of all three compounds, we used an 8E5 cell model, harboring a single HIV provirus per cell, to monitor the effects of these compounds on DNA dependent RNA polymerase (transcription) and DNA polymerase (DNA replication). The viral titers in the cell culture model showed that 10 μM of NHC had significant inhibition of MERS-CoV and LACV and moderate inhibition of ZIKV, which correlated strongly with an increase of cytosine (C) to uridine (U) transversion mutations, suggesting its mechanism for its antiviral activity is lethal mutagenesis. Both Favipiravir and Ribavirin exhibited no antiviral effects on MERS-CoV or ZIKV but had some antiviral effects on LACV. The In vivo mouse model showed that NHC had great inhibition in MERS-CoV with no significant observed mutations in the mice mRNA. The 8E5 cell model showed that neither Ribavirin or Favipiravir increased the mutation rate, but found that NHC caused an increase in the C to U mutations, suggesting there may be some long term effects of the drug. With the broad-spectrum antiviral effects of these compounds, they could potentially be able to be used to treat a wide variety of viral infections in humans, including newly emerged viruses that lack other forms of treatment.

Fundamental Collision Dynamics of Asymmetric Nanoentities Revealed by Correlated Electrochemistry and Optical Microscopy
Creators: name: Andrew D. Pendergast
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: The electrochemical characterization of complex populations by colliding single entities one-by-one often reveals heterogeneity in physical and chemical properties at the nanoscale. Collision electrochemistry has emerged as a powerful tool to probe these heterogeneities by directly measuring members of a population one-by-one. Classically, this technique has been limited to spherical and symmetric objects (ie. metal nanoparticle, polystyrene beads, and cells) that provide monotonic increases or decreases in a transient current measurement. However, asymmetric geometry populations introduce additional heterogeneity in terms of size and morphology, thereby complicating characterization from electrochemistry alone. Here, we report a correlated electrochemical and optical microscopy technique to study the collision dynamics of asymmetric, quasi-two-dimensional graphene nanoplatelets (GNPs) to decouple the effects of entity size, morphology, location, and orientation during the collision event. Upon collision with an electrode surface in the presence of ferrocenemethanol, an outer sphere redox mediator, graphene nanoplatelets generate a rich population of unique current transient responses that are not observed for symmetric objects. From these measurements, changes in the steady state current for the oxidation of ferrocenemethanol can be directly related to changes in the electrode surface area upon GNP collision, providing insight on the geometry of the single-entity | electrode interface that would be otherwise inaccessible without the two combined techniques. Additionally, this correlated technique permits deconvolution of complex current responses, revealing coupled transient events in the range of tens of seconds. This correlated technique is extended to blip-type transient responses associated with dynamic collisions on the order of hundreds of milliseconds. From correlated dark-field microscopy during the collision event, these nanoplatelets are not always observed to leave the electrode surface after colliding, however, the current response returns to a pre-collision baseline on the order of hundreds of milliseconds.  By coupling amperometric detection, optical microscopy, and finite element modelling, the transient behavior of single colliding GNPs can be deconvoluted in terms of the size and morphology of the colliding GNP, the location of the collision, and the angle of collision. This analysis can be extrapolated to a wide range of spherically asymmetric single entities including nanorods, planar nanoflakes, and nanoparticle clusters for robust and unambiguous determination of collision dynamics one-entity-at-a-time.

description: Ovarian cancer is a highly aggressive disease accounting for the majority of deaths from gynecological malignancies. Investigating the molecular mechanisms driving disease development and progression can improve early detection and drive the introduction of novel treatment strategies to ameliorate patient outcomes. Enhancing the accuracy and efficiency of ovarian cancer surgeries by introducing molecular information to rapidly assess tissue samples and guide cancer excision could also offer significant benefits to the management of ovarian cancer. Ambient ionization mass spectrometry (MS) methods are capable of obtaining biomolecule information directly from tissue samples with minimal sample preparation requirements and experimental simplicity, providing a suitable platform to conduct these investigations. Desorption electrospray ionization (DESI) was introduced in 2004 as the first ambient ionization MS technique and has been widely applied to investigate healthy and cancerous human tissue sections towards identifying potential cancer molecular markers and developing predictive statistical models towards improved cancer diagnosis. Alternative ambient ionization methods utilizing direct liquid extraction-based mechanisms have also been developed to improve the analytical capabilities of ambient ionization MS and expand applications in tissue analysis and cancer diagnosis. Overall, this dissertation presents the application and development of ambient ionization MS methods for ovarian cancer research and improved diagnostics. First, the use of DESI-MS to distinguish between malignant and borderline ovarian tumors, as well as determine metabolic markers associated with disease aggressiveness is described. Going beyond cancer diagnosis, we next apply DESI-MS to identify trends in metabolic composition resulting from the expression of the fatty acid binding protein (FABP4) gene, a molecular determinant of ovarian cancer metastasis and residual disease post-surgery. An alternative liquid extraction-based ambient ionization MS approach is also described in this dissertation to improve spatial control in MS imaging and profiling applications from biological tissue sections. The capabilities of this method are tested with various biological samples, including ovarian cancer tissue. Finally, we discuss the development of an ambient MS technology, the MasSpec Pen, envisioned for nondestructive, rapid, ex vivo and in vivo assessment of surgical specimens. We demonstrate the capabilities of this system to provide accurate diagnoses from ovarian fresh-frozen specimens ex vivo across different sample sets, utilizing various healthy and ovarian cancer tissue types and mass spectrometry platforms.
