Heroic transformation : restorying gender in My Hero Academia fanfiction
Creators: name: Kato-Hopkins, Minori
Publisher: name: University of British Columbia
Year: 2023

description: In 1993, Henry Jenkins wrote that slash fanfiction reveals “aspects of traditional masculinity which prevent emotional expressiveness of physical intimacy between men” in the ways that it allows one to “imagine what a new kind of male friendship might look like” (Jenkins, 1993, as cited in Green et al. 2006). But what male friendships are portrayed in fanfiction outside of slash, that is, in non-romantic contexts? Furthermore, what might those friendships look like in fanfictions of the shōnen manga genre, which traditionally reproduces Toxic Masculine attitudes regarding male gender expression? Building on an interdisciplinary foundation of gender studies, fandom and affinity space studies, education, and children’s literature, this thesis investigates Kohei Horikoshi’s My Hero Academia (MHA) (2014-) and its most popular work of fanfiction on Archive of Our Own, PitViperofDoom’s Yesterday Upon The Stair (YUTS) (2016-2019). Using a mixed-methods approach that combines close-reading and data-driven analyses, I compare the selected texts for their respective depictions of crying and the attitudes surrounding such expressions of emotional vulnerability by male characters. Through this analysis, I explore how fanfiction narratives such as YUTS represent fan intentions to critique and challenge the gendered tropes of the popular shōnen manga, My Hero Academia, as well as how YUTS’ restorying (Thomas & Stornaiuolo, 2016) serves as a counter-narrative against gendered assumptions in the shōnen manga tradition and its fandom activity more broadly. The findings show that YUTS provides an alternative approach to shōnen narratives that preserve the genre’s narrative structure while overtly challenging its attitudes regarding masculinity. YUTS’ in-narrative discussion of the sexualization of characters and their relationships speak directly to the fanfiction reader, posing questions about what attitudes regarding gender are perpetuated in fandom activity and in their official, “canon” counterparts. This thesis concludes with a discussion of the limitations and implications of this study, and a call to action for fandom members, academics, and the YA industry to challenge its approaches to masculinity in young adult media.
Session-Typed Concurrent Contracts

description: Multi-process systems control the behavior of everything from datacenters storing our information to banking systems managing money. Each one of these processes has a prescribed role, their contract, that governs their behavior during the joint computation. When a single process violates their communication contract, the impact of this misbehavior can rapidly propagate through the system. This thesisdevelops techniques for dynamically monitoring expressive classes of concurrent contracts. We provide multiple mechanisms to monitor contracts of increasing complexity.In order to model message-passing concurrent computation, we use a session type system. First, we present a method for dynamic monitoring and blame assignment where communication contracts are expressed using session types. Second, we describe contract-checking processes that handle stateful contracts that cannot be expressed with a session type. These contract-checking processes are also able to encode type refinements. Third, we encode dependent types in our system which allow us to monitor complex invariants. Finally, we survey a number of other monitoring extensions including a mechanism to monitor deadlock.

description: Oblivious transfer (OT) is an important cryptographic primitive. Any multi-party computation can be realised with OT as building block. XOR oblivious transfer (XOT) is a variant where the sender Alice has two bits, and a receiver Bob obtains either the first bit, the second bit, or their XOR. Bob should not learn anything more than this, and Alice should not learn what Bob has learnt. Perfect quantum OT with information-theoretic security is known to be impossible. We determine the smallest possible cheating probabilities for unrestricted dishonest parties in non-interactive quantum XOT protocols using symmetric pure states, and present an optimal protocol, which outperforms classical protocols. We also "reverse" this protocol, so that Bob becomes sender of a quantum state and Alice the receiver who measures it, while still implementing oblivious transfer from Alice to Bob. Cheating probabilities for both parties stay the same as for the unreversed protocol. We optically implemented both the unreversed and the reversed protocols, and cheating strategies, noting that the reversed protocol is easier to implement.

description: The generalized Rosenzweig-Porter model with real (GOE) off-diagonal entries arguably constitutes the simplest random matrix ensemble displaying a phase with fractal eigenstates, which we characterize here by using replica methods. We first derive analytical expressions for the average spectral density in the limit in which the size $N$ of the matrix is large but finite. We then focus on the number of eigenvalues in a finite interval and compute its cumulant generating function as well as the level compressibility, i.e., the ratio of the first two cumulants: these are useful tools to describe the local level statistics. In particular, the level compressibility is shown to be described by a universal scaling function, which we compute explicitly, when the system is probed over scales of the order of the Thouless energy. Interestingly, the same scaling function is found to describe the level compressibility of the complex (GUE) Rosenzweig-Porter model in this regime. We confirm our results with numerical tests.

description: An autistic body is a threat to the functioning of a neoliberal state. And as Israeli border police demonstrated on 30 May 2020, such a ‘late’ body with its impaired communication and social skills, is only fit to die. Eyad Al-Hallaq was not just ‘disabled’ by his autistic body but also by his racialised body. The ruthless Israeli border police therefore had no second thoughts before emptying out a bevy of bullets into this doubly disabled body of a 32-year-old Palestinian man.

description: Objective: Murmurs are abnormal heart sounds, identified by experts through cardiac auscultation. The murmur grade, a quantitative measure of the murmur intensity, is strongly correlated with the patient's clinical condition. This work aims to estimate each patient's murmur grade (i.e., absent, soft, loud) from multiple auscultation location phonocardiograms (PCGs) of a large population of pediatric patients from a low-resource rural area. Methods: The Mel spectrogram representation of each PCG recording is given to an ensemble of 15 convolutional residual neural networks with channel-wise attention mechanisms to classify each PCG recording. The final murmur grade for each patient is derived based on the proposed decision rule and considering all estimated labels for available recordings. The proposed method is cross-validated on a dataset consisting of 3456 PCG recordings from 1007 patients using a stratified ten-fold cross-validation. Additionally, the method was tested on a hidden test set comprised of 1538 PCG recordings from 442 patients. Results: The overall cross-validation performances for patient-level murmur gradings are 86.3% and 81.6% in terms of the unweighted average of sensitivities and F1-scores, respectively. The sensitivities (and F1-scores) for absent, soft, and loud murmurs are 90.7% (93.6%), 75.8% (66.8%), and 92.3% (84.2%), respectively. On the test set, the algorithm achieves an unweighted average of sensitivities of 80.4% and an F1-score of 75.8%. Conclusions: This study provides a potential approach for algorithmic pre-screening in low-resource settings with relatively high expert screening costs. Significance: The proposed method represents a significant step beyond detection of murmurs, providing characterization of intensity which may provide a enhanced classification of clinical outcomes.

description: The outcome of vertebroplasty is hard to predict due to its dependence on complex factors like bone cement and marrow rheologies. Cement leakage could occur if the procedure is done incorrectly, potentially causing adverse complications. A reliable simulation could predict the patient-specific outcome preoperatively and avoid the risk of cement leakage. Therefore, the aim of this work was to introduce a computationally feasible and experimentally validated model for simulating vertebroplasty. The developed model is a multiphase continuum-mechanical macro-scale model based on the Theory of Porous Media. The related governing equations were discretized using a combined Finite Element - Finite Volume approach by the so-called Box discretization. Three different rheological upscaling methods were used to compare and determine the most suitable approach for this application. For validation, a benchmark experiment was set up and simulated using the model. The influence of bone marrow and parameters like permeability, porosity, etc., was investigated to study the effect of varying conditions on vertebroplasty. The presented model could realistically simulate the injection of bone cement in porous materials when used with the correct rheological upscaling models, of which the semi-analytical averaging of the viscosity gave the best results. The marrow viscosity is identified as the crucial reference to categorize bone cements as high- or low- viscosity in the context of vertebroplasty. It is confirmed that a cement with higher viscosity than the marrow ensures stable development of the injection and a proper cement interdigitation inside the vertebra.

description: Ammonium persulfate is a mild oxidant capable of oxidizing the selenium-selenium bond through thermal activation or under drastic acid catalysis. In this paper we highlight that this reaction can be activated photochemically, starting from diphenyl diselenide in the absence of any organic or and/or metallic photocatalyst or additive. The protocol was applied to a well-known panel of selenoalkoxylation reactions and the obtained results clearly indicate the involvement of an electrophilic selenium reagent.

description: It is known that the spectrum of quasi-normal modes of potential barriers is related to the spectrum of bound states of the corresponding potential wells. This property has been widely used to compute black hole quasi-normal modes, but it is limited to a few "approximate" potentials with certain transformation properties for which the spectrum of bound states must be known analytically. In this work we circumvent this limitation by proposing an approach that allows one to make use of potentials with similar transformation properties, but where the spectrum of bound states can also be computed numerically. Because the numerical calculation of bound states is usually more stable than the direct computation of the corresponding quasi-normal modes, the new approach is also interesting from a technical point of view. We apply the method to different potentials, including the Pöschl-Teller potential for which all steps can be understood analytically, as well as potentials for which we are not aware of analytic results but provide independent numerical results for comparison. As a canonical test, all potentials are chosen to match the Regge-Wheeler potential of axial perturbations of the Schwarzschild black hole. We find that the new approximate potentials are more suitable to approximate the exact quasi-normal modes than the Pöschl-Teller potential, particularly for the first overtone. We hope this work opens new perspectives to the computation of quasi-normal modes and finds further improvements and generalizations in the future.

description: The excessive and irrational use of organophosphate insecticides in our lives has resulted in a serious environmental problem, necessitating the proposal of novel and cost-effective plans to remove these organophosphate insecticides from agricultural or industrial wastewater. In this approach, we investigated the use of phyllosilicate clay as a low-cost and environmentally friendly adsorbent to eliminate an organophosphate insecticide (Diazinon DZN) from an aqueous medium. To achieve an adequate elimination of this insecticide from contaminated water, three main parameters including clay dose (Dc) (0.1–1.5 g L−1), medium pH (5–9), and initial DZN concentrations (CDZN) (55–40 mg L−1) were optimized using a multivariable optimization based on Box-Behnken Design (BBD). The response surface method (RSM) and composite desirability function technique were used to find the ideal conditions for the three input variables and the adsorption amount (Qe) was selected as the output variable. The higher adsorption amount (Qmax) was achieved with an adsorbent amount of 1.5 g L−1 in an acidic medium (pH = 5) at room temperature and a Diazinon initial dose of 25.85 mg L−1, with a maximum adsorbent loading of 12.20 mg g−1. The nonlinear modeling study showed that the adsorption kinetics of Diazinon follows the pseudo-second-order model. The thermodynamic study shows that the DZN removal process is exothermic, spontaneous, and of a stable configuration.
Computationally efficient geometric methods for optimization and inference in machine learning

description: Optimization and inference are essential ingredients of machine learning (ML). Many optimization and inference problems can be formulated from a probabilistic perspective to exploit the Fisher-Rao geometric structure of a probability family. By leveraging the structure, optimization and inference methods can improve their performance. A classic approach to exploiting the Fisher-Rao structure is natural-gradient descent (NGD). However, implementing NGD remains computationally intensive. When a parameter space is constrained, it can also be non-trivial to perform NGD while taking the constraint into consideration. It is even more challenging to perform NGD in structured parameter spaces. This work pushes the boundary of the theory and practice of NGD. We first establish a connection among NGD, mirror descent (MD), and Riemannian gradient descent (RGD). Thanks to this connection, we consider various approaches to better exploit underlying geometric and algebraic structures of NGD resulting in computationally efficient and practically useful methods for inference and optimization problems in ML. In the first part of this work, we reduce the computational cost of NGD for exponential family approximations in variational inference. To do so, we exploit a convex duality in MD by viewing NGD as a MD update. Secondly, we extend the scope of NGD and develop efficient methods by exploiting a similar duality for mixtures of exponential family approximations. Mixtures are more powerful than the exponential family to model complex distributions. We introduce a new Fisher-Rao metric for a mixture since the original Fisher-Rao metric becomes singular in mixture cases. The third part of this work addresses the constraint issue in NGD by proposing a new efficient update scheme inspired by RGD. We focus on performing NGD updates in positive-definite constrained parameter spaces as these spaces appear in exponential family distributions and their mixtures. Finally, we enable a practical usage of NGD methods in structured and constrained parameter spaces by using tools from Riemannian geometry. We propose a structure-preserving NGD update scheme by using matrix Lie groups and moving coordinates. Thanks to our approach, we also develop novel structured second-order methods for unconstrained optimization and adaptive gradient-based methods for deep learning.

description: A leading direction in the hunt for axion dark matter is to search for its influence on nuclear spins. The detection scheme involves polarizing a sample of nuclei within a strong static magnetic field and then looking for a spin precession induced by the oscillating axion field. We study the axion signal and background contributions that arise in such experiments (a prominent example being CASPEr), finding key differences with the existing literature. Most importantly, in the limit where the transverse spin-relaxation time of the material is the largest timescale of the problem, we show that the induced signal continues to grow even beyond the coherence time of the axion field. As a result, we find that spin-precession instruments are much more sensitive than what has been previously estimated in a sizable range of axion masses, with sensitivity improvement of up to a factor of 100 at an axion mass of 100 neV using a Xenon-129 sample. This improves the detection prospects for the QCD axion, and we estimate the experimental requirements to reach this motivated target. Our results apply to both the axion electric and magnetic dipole moment operators.

description: This paper proposes to generalize linear subdivision schemes to nonlinear subdivision schemes for curve and surface modeling by refining vertex positions together with refinement of unit control normals at the vertices. For each round of subdivision, new control normals are obtained by projections of linearly subdivided normals onto unit circle or sphere while new vertex positions are obtained by updating linearly subdivided vertices along the directions of the newly subdivided normals. Particularly, the new position of each linearly subdivided vertex is computed by weighted averages of end points of circular or helical arcs that interpolate the positions and normals at the old vertices at one ends and the newly subdivided normal at the other ends. The main features of the proposed subdivision schemes are three folds: (1) The point-normal (PN) subdivision schemes can reproduce circles, circular cylinders and spheres using control points and control normals; (2) PN subdivision schemes generalized from convergent linear subdivision schemes converge and can have the same smoothness orders as the linear schemes; (3) PN $C^2$ subdivision schemes generalizing linear subdivision schemes that generate $C^2$ subdivision surfaces with flat extraordinary points can generate visually $C^2$ subdivision surfaces with non-flat extraordinary points. Experimental examples have been given to show the effectiveness of the proposed techniques for curve and surface modeling.

description: Reaction of Cy2NH with CS2 in NaOH/H2O, followed by oxidation with I2, yields a complex mixture that includes the tetracyclohexylthiuram disulfide, Cy2NC(S)SSC(S)NCy2, in mixture with S8 and the tetrasulfide Cy2NC(S)SSSSC(S)NCy2. Direct reaction of 2 eq of Cy2NH with CS2 in EtOH, followed by I2 oxidation, does not yield isolable Cy2NC(S)SSC(S)NCy2, even though other tetraalkylthiuram disulfides are effectively produced by this protocol. Deprotonation of Cy2NH with tBuLi, followed by treatment with CS2 and then oxidative coupling with I2 yields Cy2NC(S)SSC(S)NCy2 in ∼74% yield, suggesting secondary amines that are branched at the α carbon may generally require this lattermost approach to the corresponding tetraalkylthiuram disulfide. Evaporation of an Et2O solution of the crude product mixture obtained from the CS2/NaOH/H2O reaction yielded a triclinic form of Cy2NC(S)SSC(S)NCy2, which contained two independent molecules in its asymmetric unit with opposite C2 handedness. This same product mixture contained Cy2NC(S)SSSSC(S)NCy2, which was identified crystallographically in monoclinic C2/c and is the first such tetrasulfide to be characterized by X-ray diffraction. A second polymorph of Cy2NC(S)SSC(S)NCy2, obtained by evaporation of an acetone solution, is disordered across a mirror plane in monoclinic P21/m. This monoclinic polymorph of Cy2NC(S)SSC(S)NCy2 is the only tetraalkylthiuram disulfide found to crystallize on a mirror plane.

description: A crude morpholine enamine of acetone treated with Lawesson’s reagent unexpectedly yielded a six-membered thiaphosphinane-4-one. This compound is the first example of a new class of heterocycles. It has been proven that it is formed from 4-methyl-2-morpholino-1,3-pentadiene which is usually present in crude morpholine enamine batches. A mechanism of this regioselective reaction was postulated and a characteristic chair-like conformation of the product was examined in detail. Additionally, some unusual primary fragmentations of the product with the loss of H2S and isobutylene were observed for positive and negative ESI ionization mode, respectively.

description: The performance of machine learning based network intrusion detection systems (NIDSs) severely degrades when deployed on a network with significantly different feature distributions from the ones of the training dataset. In various applications, such as computer vision, domain adaptation techniques have been successful in mitigating the gap between the distributions of the training and test data. In the case of network intrusion detection however, the state-of-the-art domain adaptation approaches have had limited success. According to recent studies, as well as our own results, the performance of an NIDS considerably deteriorates when the `unseen' test dataset does not follow the training dataset distribution. In some cases, swapping the train and test datasets makes this even more severe. In order to enhance the generalisibility of machine learning based network intrusion detection systems, we propose to extract domain invariant features using adversarial domain adaptation from multiple network domains, and then apply an unsupervised technique for recognising abnormalities, i.e., intrusions. More specifically, we train a domain adversarial neural network on labelled source domains, extract the domain invariant features, and train a One-Class SVM (OSVM) model to detect anomalies. At test time, we feedforward the unlabeled test data to the feature extractor network to project it into a domain invariant space, and then apply OSVM on the extracted features to achieve our final goal of detecting intrusions. Our extensive experiments on the NIDS benchmark datasets of NFv2-CIC-2018 and NFv2-UNSW-NB15 show that our proposed setup demonstrates superior cross-domain performance in comparison to the previous approaches.

description: Carbonyl dichloride (COCl2), also known as phosgene, is a highly toxic gas, whose exposure or acute inhalation causes severe respiratory complications, such as pulmonary edema, pulmonary emphysema, and even death. In this study, we theoretically investigated the complexes formed by the interaction between the COCl2 (phosgene) and OCY molecules (Y = S, Se, and Te). Complex geometry optimization yielded three distinct types of conformations. Conformation-I complexes were stabilized by two concurring chalcogen-bonding interactions (i.e. O⋯Y and Cl⋯Y) by forming a ring structure. However, only a single linear interaction (O⋯C) or (O⋯Cl) occurred in conformation-II and III complexes, forming complexes with the nature of tetrel and halogen bonds, respectively. According to the results of the molecular electrostatic potential (MEP), interaction energy (ΔET), natural bond orbital (NBO), and so on, the σ-hole of the Y atom in the OCY molecule exhibited higher acidic strength and formed more stable complexes than those resulting from the σ- and π-holes of the COCl2 molecule.

description: The exponentially growing number of scientific papers stimulates a discussion on the interplay between quantity and quality in science. In particular, one may wonder which publication strategy may offer more chances of success: publishing lots of papers, producing a few hit papers, or something in between. Here we tackle this question by studying the scientific portfolios of Nobel Prize laureates. A comparative analysis of different citation-based indicators of individual impact suggests that the best path to success may rely on consistently producing high-quality work. Such a pattern is especially rewarded by a new metric, the $E$-index, which identifies excellence better than state-of-the-art measures.

title: The interplay between foreign direct investment, security and European integration by comparing Poland and Romania
Creators: name: Stoian, Carmen R.

description: This work investigates the factors that have led to Poland and Romania's different evolutionary paths during the process of accession to the EU, placing an emphasis on security concerns, foreign direct investment and the interplay between the two. We identify two sets of determinants of the accession process, one in the political sphere and one in the economic sphere. Each set of determinants, be it in the political or economic sphere, has the potential to constitute a vicious or a virtuous circle which includes the prospect of EU membership itself. Furthermore, each of these circles is self reinforcing and can reinforce the corresponding circle in the other sphere. Finally, political and economic elements of the circles considered here can constitute security concerns for each of the countries analysed, while FDI represents a main element of the economic circle. We find that until 1996 Romania has been trapped in a combination of two vicious circles in both the political and economic spheres, while Poland has benefited from a combination of two virtuous circles since 1993. We test the hypothesis that, by changing perceptions of security and enhancing FDI, the prospect of EU membership can break the vicious economic circle of high perceptions of insecurity, low FDI, slow reforms, poor prospects for EU integration and hence high perceptions of insecurity in which Romania has been trapped. This is achieved firstly by a qualitative comparative analysis between Poland and Romania with regard to the determinants of FDI and the nature of their security concerns. Secondly, an econometric model assesses the determinants of FDI in ten transition countries candidates for EU membership and in particular the role of security and European integration variables. Our results support the hypothesis that, by creating positive perceptions of security of the candidate countries (especially of poor reformers), the prospect of EU membership may enhance FDI, thus speeding up economic reforms, leading to full membership of the Union and hence positive perceptions of security.It also appears that the prospect of EU membership can lead to a virtuous circle in the economic sphere through providing motivation for economic reforms and through financial aid and its impact on foreign direct investment and economic reforms.

description: Die politische Rolle der Markgräfin Wilhelmine ist insbesondere von der borussischen Forschung nicht zuletzt durch systematische Aussparung ganzer Briefe oder Briefpassagen in ihrer Korrespondenz mit König Friedrich II. minimiert worden. Wie aktiv sie tatsächlich an der Seite ihres Gemahls Friedrich III. von Bayreuth diese Rolle gespielt hat, zeigen die beiden Subsidienverträge, die das fränkische Markgraftum in den Jahren 1751 und 1757 mit Frankreich abgeschlossen hat: An der Ausgestaltung des ersten Vertrags wirkte sie durch hartnäckiges Feilschen um möglichst günstige Bedingungen in etlichen Schreiben an König Friedrich als Garanten des Vertrags mit. Den zweiten, explizit gegen England und Preußen gerichteten Vertrag, der hier erstmals publiziert wird, sicherte sie gegenüber dem königlichen Bruder durch Ablenkungs- und Verschleierungsmanöver in Form von Informationen über politisch-militärische Operationen seiner Gegner in der Anfangszeit des Siebenjährigen Krieges ab.

description: The paper proposes a novel, integrated approach to the identification and quantification of the organic binders, mainly proteinaceous, as the “invisible” component of polychrome layers in artifacts belonging to movable and immovable cultural heritage. The analytical methodology discussed here will demonstrate the significance and efficiency of biochemical assays for the detection of organic binders and how these tests can improve/complement the already existing techniques, while considering also the costs and time of analysis that commonly limit their application in the current laboratory practice for artworks diagnosis.
