Publisher: name: Zenodo

Subjects: Sound Event Detection; Data Augmentation; DCASE

description: Everyday environments are overflowed with a wide variety of acoustic events, either produced by humans, animals, or objects. The identification of the class of a sound and its relative persistency time boundaries can open several opportunities and applications in different fields such as smart homes, autonomous cars, smart cities, industrial fault detection, surveillance systems, and healthcare. Therefore, Sound Event Detection (SED) systems have gained great attention in the past few years, especially driven by the new opportunities coming from the application of different types of Neural Networks (NNs) to the SED task. The performances of these systems can heavily depend on the availability of a large amount of strongly labeled data especially for model training. Gathering or retrieving this data is often difficult and costly. Synthetic data frequently offer a solution to increase the availability of information but they can lead the model to face overfitting problems. The objective of this work is to explore, combine and compare different data augmentation (DA) techniques to balance out the lack of strongly labeled data and to mitigate the possible overfitting scenario introduced by the use of synthetic data. For the aim of this investigation, the Detection and Classification of Acoustic Scenes and Events (DCASE) Challenge 2022 has been chosen as a laboratory for DA methods exploration. As an additional contribution, the best result has been submitted to the Task4 of the challenge.
 The first part of the manuscript provides a brief introduction followed by an overview of the state-of-art of the SED systems and their relative data augmentation techniques. Secondly, the experiment strategy and methodology are presented. Finally, all results are reported and documented introducing the possible future contributions.
Austenite Formation in Low Carbon Microalloyed Pipeline Steels
Creators: Hintze Cesaro, Alejandro
Publisher: name: University of Alberta Library
Year: 2022

A study of the kinetic and microstructural aspects of austenite formation in

low carbon pipeline steels during continuous heating and a model capable to

predict the interface velocity are presented in this study. The overall goal of

this work is to increase the level of understanding concerning the austenite

reversion in low carbon pipeline steels. This work builds on top of the theory

of solute drag and a Gibbs energy balance approach, and expands this theory

to account for the effect of Mn redistribution at slow heating rates.

Due to the unique characteristics of commercial pipeline steels, given by

a refined chemical composition and tailored steel processing conditions, the

initial microstructure previous to the austenite transformation was carefully

studied to ponder all the relevant transformation conditions during continuous heating. Dilatometry experiments were employed to construct a continuous heating transformation (CHT) diagrams and study the kinetics and

microstructural aspects of two commercial X80 pipeline steels.

Experimental results suggested that orthoequilibrium calculations are

poor predictor of the transformation temperatures and that the mechanisms

controlling the transformation kinetics are susceptible to the heating rate. To

obtain a better understanding of the transformation kinetics, a Gibbs free

energy balance across the interface was employed to calculate the boundary

migration rate as a function of the available driving force. This energetic approach was supported by an original methodology to calculate the chemical

driving force under paraequilibrium conditions coupled with a modification

of the solute drag model. The calculation was applied for continuous heating

transformation at 1 ◦C/s and 200 ◦C/s.

The results of this work serve to bring a deeper understanding on how

austenite is formed during continuous heating. In particular to highlight the

differences between slow (conventional heat treatments) and fast (welding)

heating rates.

description: Este artigo trata da qualidade do atendimento público, com foco na atuação dos servidores sob a perspectiva da qualidade e eficiência para os cidadãos-usuários. Nesse sentido, o propósito do estudo foi analisar a consolidação das políticas de atendimento em uma universidade pública na cidade de Barreiras, Bahia, e, com esse objetivo, desdobrou-se em objetivos específicos: avaliar o nível de satisfação dos cidadãos-usuários com o atendimento prestado na instituição; conhecer as estratégias de melhoria no atendimento adotadas pela instituição de ensino; verificar a efetivação das leis e normas de atendimento aos cidadãos na instituição. Para subsidiar as discussões e análises dos dados, a fundamentação teórica baseou-se na Constituição Federal do Brasil de 1988, no Decreto nº 1.171/1994, no Código de Ética Profissional do Servidor Público Civil do Poder Executivo Federal, na Lei nº 8.429/1992 - Improbidade Administrativa, na Lei nº 8.112/1990 - Regime Jurídico dos Servidores Públicos Civis da União, além das obras de Silva (2021), Moscovici (1999) e Bonifácio (2023), para abordar tanto a trajetória da administração pública quanto a oferta do serviço público, avaliação, estratégias e a qualidade no atendimento. A metodologia adotada incluiu pesquisa exploratória, com abordagem bibliográfica e pesquisa documental, utilizando um questionário de opinião. Nessa perspectiva, a pesquisa a partir do questionário permitiu uma visão específica sobre o atendimento na instituição pública. Os resultados apontaram a importância da comunicação entre os cidadãos/usuários e a administração para melhorar o serviço na instituição, a subjetividade nas respostas dos pesquisados, o desconhecimento das leis que regem o serviço público e dos instrumentos de avaliação da instituição, bem como a satisfação dos usuários/cidadãos com o serviço prestado. Na análise dos dados, percebe-se o quanto é relevante agregar valores estratégicos e de avaliação, assim como a formação dos agentes públicos. Ademais, destaca-se a relevância deste estudo, dada a amplitude e a complexidade do tema. Acredita-se também que a administração pública precisa entender as questões coletivas e encontrar estratégias que legalmente garantam os direitos dos cidadãos.
A hybrid method of generating spin-squeezed states for quantum-enhanced atom interferometry

description: We introduce a new spin-squeezing technique that is a hybrid of two well established spin-squeezing techniques, quantum nondemolition measurement (QND) and one-axis twisting (OAT). This hybrid method aims to improve spin-squeezing over what is currently achievable using QND and OAT. In practical situations, the strength of both the QND and OAT interactions is limited. We found that in these situations, the hybrid scheme performed considerably better than either OAT or QND used in isolation. As QND and OAT have both been realised experimentally, this technique could be implemented in current atom interferometry setups with only minor modifications to the experiment.

description: In this paper, we extend purely non-local Hamiltonian formalism to a class of Riemannian F-manifolds, without assumptions on the semisimplicity of the product $\circ$ or on the flatness of the connection $\nabla$. In the flat case we show that the recurrence relations for the principal hierarchy can be re-interpreted using a local and purely non-local Hamiltonian operators and in this case they split into two Lenard-Magri chains, one involving the even terms, the other involving the odd terms. Furthermore, we give an elementary proof that the Kohno property and the $\vee$-system condition are equivalent under suitable conditions and we show how to associate a purely non-local Hamiltonian structure to any $\vee$-system, including degenerate ones.

Recursive Session Types Revisited

Publisher: name: arXiv
Year: 2014
Subjects: subject: Programming Languages (cs.PL)
subject: FOS: Computer and information sciences

description: Session types model structured communication-based programming. In particular, binary session types for the pi-calculus describe communication between exactly two participants in a distributed scenario. Adding sessions to the pi-calculus means augmenting it with type and term constructs. In a previous paper, we tried to understand to which extent the session constructs are more complex and expressive than the standard pi-calculus constructs. Thus, we presented an encoding of binary session pi-calculus to the standard typed pi-calculus by adopting linear and variant types and the continuation-passing principle. In the present paper, we focus on recursive session types and we present an encoding into recursive linear pi-calculus. This encoding is a conservative extension of the former in that it preserves the results therein obtained. Most importantly, it adopts a new treatment of the duality relation, which in the presence of recursive types has been proven to be quite challenging.

description: This paper outlines a provisional impact model for the social integration of young refugees in German sports clubs through sports programmes. The questions ‘what works, under what circumstances, and for whom?’ are explored based on a Realist Evaluation of these pro-grammes’ integration goals. For this purpose, the sports programmes for refugees of se-lected sports clubs were examined by considering: (1) the available requests for funding and reports produced by the clubs; (2) guideline-based interviews with the clubs’ contact persons; and (3) participant observations of selected programmes. The resulting data (documents, transcriptions and observation protocols) were analysed qualitatively and in-terpreted using Esser’s conceptualisation of integration. The impact model shows that inte-grative processes were observable within the sports programmes examined. To facilitate these processes, sport must ‘show its best side’, which cannot be taken for granted. More-over, the relevance of sport as a means of integration could not be weighed, because the in-fluencing factors are numerous, complex and interrelated. Hence, what is portrayed as the integrative power could be the result of more complex psychosocial processes that manifest themselves in sport. Theory-guided and empirically-based evaluations may contribute to the development of a more objective reflection on integration in/through sport.
Direct photon production as a probe of quarks chromoelectric and chromomagnetic dipole moments at the LHC

description: In this paper we show that the $γ+$jet invariant mass distribution in proton-proton collisions at the LHC is significantly sensitive to the quarks chromoelectric ($κ$) and chromomagnetic ($\tildeκ$) dipole moments. It is shown that the presence of $κ$ or $\tildeκ$ leads to an increment of the cross section of $γ+$jet process in particular in the tail of $γ+$jet invariant mass distribution. Using the measured $γ+$jet invariant mass distribution by the CMS experiment at the center-of-mass energy of 8 TeV, we derive bounds on the quarks chromoelectric and chromomagnetic dipole moments. In extraction of the limits, we consider both theoretical and systematic uncertainties. The uncertainties originating from variation of the renomalization/factorization scales and the choice of proton parton distribution functions are taken into account as a function of the $γ+$jet invariant mass. We exclude $κ$ or $\tildeκ$ above $10^{-5}$ at 95$\%$ confidence level. This is the most stringent direct upper limit on $κ$ or $\tildeκ$.

A Comparative Study On Improving Sound Similarity Maps With Semantic Metadata

Subjects: Sound similarity maps; Dimensionality reduction; Sample browsing

description: Searching and browsing appropriate sounds within large collections of audio samples can be challenging for musicians and sound designers. Most commonly, list-based search approaches are being used for displaying content for music production, however,
 several attempts have been made to improve user experience by projecting sounds on a two-dimensional map. These maps usually rely on dimensionality reduction methods like PCA, UMAP, or t-SNE to translate an audio embedding or another high dimensional feature representation into a low dimensional latent space, which typically involves a trade-off between the preservation of the global and local structure of the data. Providing metadata or custom distance measures to the algorithms can improve the clustering but requires correct labels and a solid feature representation. In this work, we address this issue by including user metadata for
 classification refinement of the audio to achieve an improved label description and post-process the point positions of the projection with the help of class probabilities. We conducted a comparative study of different map layouts to understand the usefulness of the aforementioned method to improve sound similarity projections. In our study, we found that hierarchically adding semantics and having a more concise local structure benefits both sound searching and explorational browsing.
 The methods presented in this thesis have potential applicability in other research domains involving classification and projection tasks.

description: The Taub-NUT geometry corresponds to the Kaluza-Klein monopole solution of M-theory and on dimension reduction along the Taub-NUT circle direction it becomes the D6 brane of type IIA string theory. We show that the Taub-NUT geometry can be realised as a coherent state, or more appropriately as a Glauber-Sudarshan state in M-theory, once we take the underlying resurgence structure carefully. Using the duality chain it in turn implies that all D-branes as well as NS5-branes can be realised as Glauber-Sudarshan states in string theory. Our analysis also leads to an intriguing possibility of realizing the gravity duals of certain non-conformal minimally-supersymmetric gauge theories by deforming a class of Glauber-Sudarshan states.

Memory Enhancement via Mnemonic Scaffolds
Creators: Kluger, Felicitas E.
Publisher: name: University of Alberta Library
Year: 2022

Mnemonic techniques can enable learners to memorize vast amounts of information at first

encounter. The most effective mnemonic techniques harness mnemonic scaffolds, memory

structures of prior knowledge, to which new information is associated. As impressively

demonstrated by memory athletes, training in mnemonic scaffolds can lead to superior memory

performance and greatly exceed untrained levels of human memory. Importantly, memory

athletes neither have extraordinary brain anatomy nor innate memory capacity— their

superior memory is attributed to skilled use of mnemonic scaffolds.

Here, we investigate mnemonic scaffolds in novice learners. Our studies include four

novel mnemonic scaffolds consisting of different types of prior knowledge and the renowned

Method of Loci. Our participants generated their own scaffolds and used them to study

word lists in serial order. In addition to the serial recall task, they performed a scaffold-cued

recall task, in which they were shown parts of their scaffold as cues to verify whether they

used their scaffolds as instructed.

In Chapter 2, we introduce the Autobiographical Story Scaffold. In Chapter 3, we compare

autobiographical to fictional stories as mnemonic scaffolds for lists of fifteen words.

In Chapter 4, we compare the Body Scaffold, Autobiographical Story Scaffold, and Routine

Activity Scaffold to the Method of Loci and ask whether individual differences in visual

imagery and body responsiveness contribute to their effectiveness. We also ask whether

different levels of engagement of the body predict the success of the Body Scaffold.

Unlike previous studies, including a formal scaffold-generation phase and a scaffold-cued

recall task in all our experiments ensures that success with the strategy can be attributed

to participants actually implementing the strategy as instructed. In addition, ours is the first within-experiment comparison that has revealed differences between different kinds of

scaffolds, suggesting that the scaffolds, themselves, could be optimized.

Across all our experiments we have found that not all scaffolds are equally effective, and

that the Body Scaffold is on par with the Method of Loci. The ability to form individual

scaffold-word associations is a driving factor behind the successful use of mnemonic scaffolds.

Embodied cognition, imagined navigation, and visual imagery aptitude may not contribute to

their effectiveness. With further fine-tuning of the scaffolds and the way they are instructed,

mnemonic scaffolds can be used to greatly boost learning performance.
The role of Receptor Interacting Serine/Threonine Kinase 2 (RIPK2) in inflammatory breast cancer (IBC)
Creators: Zare, Alaa
Publisher: name: University of Alberta Library
Year: 2022

Inflammatory breast cancer (IBC) is a rare but aggressive type of breast cancer characterized by early and rapid metastasis leading to poor clinical outcomes. The tumor microenvironment (TME), including immune cells, fibroblasts and endothelial cells, has emerged as a major regulator of IBC aggressiveness, however little is known about how IBC cells may orchestrate this pro-tumorigenic milieu. This work helps us understand the importance of TME in promoting IBC metastatic behavior. Recent studies indicated that inflammatory pathways such as NF-κB concomitant with the secretion of cytokines are key elements in nurturing the IBC TME. Although NF-κB and its target genes are known to be upregulated in IBC tumor samples, its direct effect has never been studied. Herein, I show for the first time how NF-κB activation through the receptor tyrosine kinase RIPK2 can contribute to IBC progression by promoting metastatic phenotypes in cancer cells. Specifically, RIPK2 was shown to promote an inflammatory transcriptome in IBC cells leading to the secretion of factors such as IL-8, IL-6 and Activin-A.  As a corollary, RIPK2 enhanced key IBC phenotypes, including angiogenic potential and metastatic growth in the lung.  I also demonstrate the status of RIPK2 activity in IBC tumor samples using a special monoclonal antibody directed against the phosphorylation site Y474 utilizing IBC cell models and patient tumor samples. Elevated levels of RIPK2 phosphorylation were present in IBC samples collected at the time of diagnosis. However, chemotherapy did cause an increase in RIPK2 activity, suggesting its role in augmenting inflammation in breast tissue, which subsequently can lead to treatment resistance. Further, RIPK2 activity correlated with tumor, metastasis, and overall group stage, as well as body mass index (BMI), to indicate that RIPK2 might be a useful prognostic marker for IBC. In addition, I help identify a robust gene signature able to differentiate IBC samples from non-IBC. We report a novel IBC-specific gene signature (59 genes; G59) that achieves 100% accuracy in discovery and validation samples and remarkably only misclassified one sample in an independent dataset. G59 is independent of ER/HER2 status, molecular subtypes and is specific to untreated IBC samples, with most of the genes being enriched for plasma membrane cellular component proteins, interleukin (IL), and chemokine signaling pathways. Our finding suggests the existence of an IBC-specific molecular signature, paving the way for the identification and validation of targetable genomic drivers of IBC.In conclusion, this thesis has revealed, for the first time, a critical role for RIPK2 in the regulation of IBC phenotypes. These results suggest that RIPK2 may be an attractive target for this poorly managed disease.
Monitoring Airborne Inoculum of Sclerotinia sclerotiorum at Canola Flowering and Relationships to Weather Conditions and Disease Incidence and Severity
Creators: McBain, Eleanor
Publisher: name: University of Alberta Library
Year: 2022

Sclerotinia stem rot, caused by Sclerotinia sclerotiorum, is an important disease of canola (Brassica napus). Disease development is highly dependent on weather conditions and is initiated by infection of the petals by airborne ascospores, followed by mycelial progression into leaf and stem tissues. Improved stem rot forecasts would facilitate improved fungicide application decisions, reducing costs and enhancing disease control. Various methods to monitor airborne inoculum of S. sclerotiorum were compared and related to stem rot incidence and severity. These included a passive spore trap (Spornado) and petal test kits from private seed testing laboratories, as well as a GRIPST-2009 rotation impact sampler (rotorod). Canola petal samples were also tested for S. sclerotiorum infection by the Plant Health Lab, Alberta Agriculture, Forestry and Rural Economic Development. Petal infestation levels (coupled with weather variables) provided the strongest linear relationship to disease incidence (R2 = 86%) and severity (R2 = 87%) during early-mid flowering, when fungicide application decisions are made. However, the strength of the relationship varied during the flowering period. The airborne spore traps did not show as strong of a relationship to stem rot levels as the petal tests, with the Spornado accounting for 48% and 40% of the variation in disease incidence and severity, respectively, and the rotorod accounting for 52% and 50% of the variation. Significance testing of petal, Spornado and rotorod samples taken from five different locations within a field did not show different population means, suggesting that one sample per field may be sufficient for monitoring purposes; however, more testing is required, especially across fields of different sizes. Quantification of S. sclerotiorum DNA on petal and rotorod samples by quantitative PCR indicated that 1.0 × 10-4 ng DNA per canola petal or per cubic meter of air per hour during early flowering would result in a disease incidence >15%, the level at which fungicide application is generally recommended. Given the wide range of variables affecting Sclerotinia stem rot development, an integrated disease forecasting approach, which includes monitoring of ambient weather conditions and an inoculum detection method, should be employed to determine the optimal timing of fungicide applications.
Embracing the Friction: Towards a computationally aware approach to humanistic data interfaces
Creators: Sollazzo, Anna
Publisher: name: University of Alberta Library
Year: 2022

Inherent to interdisciplinary work is the negotiation of two or more sets of—often contradictory—domain epistemologies and methodologies. In the context of the Digital Humanities, the friction between its composite domains is particularly strong with respect to data processing and display, where the ambiguity, complexity, and nuance that characterise humanities data stand in opposition to the binary and discrete representations required by computationally compatible encodings. Digital Humanities data interfaces have historically submitted to the simplification and categorisation imposed by prevalent forms of scientific visualisation, and previous work imagining interfaces better suited to humanistic inquiry has largely focused on augmenting these standards. In this thesis I explore the potential of instead stripping away layers of abstraction to expose, centre, and challenge the principles and assumptions underpinning them. This work is built around a proof of concept of interface in this alternative style that is modelled after natural language database query systems, but which atypically exposes each step and difficulty of the question to query translation. I argue that an approach that forefronts human to machine conceptual mapping both addresses key humanistic concerns such data trajectory and user positionality, and also has an important capacity to engage with questions of computational possibility and limits. The theoretical grounding implied in the latter is essential to the elaboration of novel and critically conscious technologies that embody humanistic principles.

Wetting is the process where solid surfaces attempt to create a common interface when they come in contact with the liquid droplets. To characterize the wetting and spreading between a liquid droplet and a solid surface, various techniques have been established. The most common technique have been used past over two decades is the measurement of contact angle, defined as the angle formed at the interface where all three phases (solid, liquid, surrounding medium) meet. Although contact angle measurements have been studied for over 200 years, the authentic procedure or guidelines to measure contact angle is still in debate. Some authors prefer to quantify surface wettability using dynamic contact angles, whereas some authors report static contact angles measured between a liquid drop sitting on a solid surface. This study discusses the alternative and reliable method for quantification of wettability and adhesion, \textit{i.e,} adhesion force-based measurements using a micro-electronic mechanical balance system. In this technique, a drop holder is suspended and a liquid drop of the desired volume is generated at the tip of the holder facing toward the characterizing substrate. A series of commands has been initialized such as interaction and formation of solid-liquid interface, compression, retraction, and drop detachment, while continuously recording the interactive vertical forces, experienced by the force sensor. There are various parameters/variables involved in this study, which resulted in the variation of droplet base diameter and eventually affect adhesion force. These parameters such as drop volume, retracting speed, and compression allow to maneuver the adhesion force to obtain the required adherence or attachment between two surfaces. After establishing the guidelines to record reproducible and repeatable ( R \& R) results and studying the effect of these commonly operating parameters on adhesion force, we have also discussed the effect of the surrounding medium and performed experiments in the liquid medium. Unlike the air medium, we observed that the force sensor experienced other forces as well along with interactive forces underwater. Forces such as buoyancy and hydrostatic pressure must be subtracted from total vertical force to get absolute adhesion force. Lastly, components of adhesion force; surface tension, and Laplace pressure force are also critically analyzed with respect to drop volume and compression. This study also introduces the normalization of total adhesion force and its components to negate the influence of varied droplet base diameter.

description: For a rotating black hole to be nonsingular, it means that there are no spacetime singularities at its center. The destruction of the event horizon of such a rotating black hole is not constrained by the weak cosmic censorship conjecture, which may provide possibilities to understand the internal structure of black hole event horizons. In this paper, we employ test particles with large angular momentum and a scalar field with large angular momentum to investigate the potential of destroying the event horizon of rotating Black-Bounce black holes. Additionally, we investigate the possibility of destroying the event horizon of a rotating Black-Bounce black hole by considering test particles with large angular momentum and scalar fields with large angular momentum, covering the entire range of the rotating Black-Bounce black hole. We analyze the influence of the parameter m on the possibility of destroying the event horizon in this spacetime. Our analysis reveals that under extreme or near-extreme conditions, the event horizon of this spacetime can potentially be destroyed after the absorption of particles energy and angular momentum, as well as the scattering of scalar fields. Additionally, we find that as the parameter m increases, the event horizon of this spacetime model becomes more susceptible to destruction after the injection of test particles or the scattering of scalar fields.

The Econometrics of Hope
Creators: Chorieva, Nargiza
Publisher: name: University of Alberta Library
Year: 2022

We rarely think of hope as a determinant of economic outcomes. Yet it has been shown to be a motivator of human behavior in the fields of psychology and anthropology. Recent studies have incorporated the longstanding psychological concept of hope into economics, but have failed to pay sufficient attention to measurement and statistical considerations that are required to operationalize hope within empirical econometric frameworks. This study applies advanced measurement techniques on hope survey data to derive hope measures that are meaningful for economic analysis. Our first objective is to ascertain the efficacy of standard survey measures of hope used commonly in the psychology literature. Our second objective is to assess possible sources of heterogeneity between individuals with different demographic characteristics and access to public services. To meet our objectives, we rely on a set of primary data collected in two rural regions of Tanzania with a wealth of mindset questions (e.g., hope, aspirations, self-efficacy, social cohesion). We address our first objective using Item Response Theory (IRT) methods. We find clear evidence that respondents perceive positive and negative questions differently. The former performs well at discriminating people with low levels of hope, while the latter are useful for identifying individuals with high levels of hope. With regards to our second objective, which we address using Differential Item Functioning (DIF) methods, we find significant evidence of heterogeneity. For example, we found high DIF in the responses of adults and adolescents. For instance, if DIF is ignored, adolescents will be erroneously scored as less hopeful than adults. These findings help us understand psychological differences that underpin subgroup responses and allow us to consider them while making causal analyses.

description: In the setting of session behaviours, we study an extension of the concept of compliance when a disciplined form of backtracking is present. After adding checkpoints to the syntax of session behaviours, we formalise the operational semantics via a LTS, and define a natural notion of checkpoint compliance. We then obtain a co-inductive characterisation of such compliance relation, and an axiomatic presentation that is proved to be sound and complete. As a byproduct we get a decision procedure for the new compliance, being the axiomatic system algorithmic.

Edu-Crafting Teacher Identities: Diffractive Auto/ethnography through Cartomancy
Creators: Hostetler, Angela
Publisher: name: University of Alberta Library
Year: 2022

“Teacher identity” is a popular topic for discussion and reflection in teacher education programs. We ask pre-service teachers to consider pervasive cultural and personal images of teachers (as expert, caregiver, authoritarian, and so on) in order to accept or resist these images as they contribute to the construction of their own teacher identity. Discussed in theory and aspirational language, teacher identity appears to behave in a reasonably orderly fashion; however, once the novice teacher is introduced to the dynamic world of teaching, teacher identity can become an absolute mess to untangle. As an approach to research, posthumanism offers us a chance to see this mess as beautiful in its lively, evolving, and relational condition. This posthumanist project takes to heart that in order to understand concepts such as identity differently, we must also look differently. After Taylor (2018), who describes posthumanist research as “allowing oneself to be lured by curiosity, surprise, and wonder” (p. 377), I conduct a diffractive auto/ethnographic study to find out what happens if I take seriously the value of play in research, wondering what can be gained, in terms of understandings of teacher identities, through cartomancy (i.e., tarot readings) as a potential source of knowledge. This unconventional approach to research allows me to give generous attention to these teachers’ identities by acknowledging their connections to other selves, other humans, non-humans, and more-than-humans. Through this project, I find an expanded sense of self-perception and an increased recognition of a teacher’s multiple, connected, changing, and changeable identities.
