description: A single field matter bounce with an exponential potential is numerically studied. The quantum bounce prescribed when the kinetic term dominates the evolution of the background were already demonstrated in the literature. To form a com- plete background, the quantum bounce is matched with the classical exponential- potential-driven evolution, which presents a past matter attractor. This configu- ration allows two possible mutually excluding scenarios: case A, in which a Dark Energy (DE) epoch is present in the contraction phase and case B, in which DE is present in the expansion phase. The latter is used as the background to study the cosmological perturbations. The evolution of the primordial scalar and tensor modes from vacuum initial condi- tions shows a consistent power spectra with the right amplitudes, tensor-to-scalar ratio and spectral index.
 Since bounce cosmologies suffers from the growth of anisotropy during contrac- tion phase, a matter bounce driven by a Galileon scalar field with an ekpyrotic potential is studied. Previous studies with this model claims that the final back- ground dynamics suppresses the anisotropy growth. In the last part of this work, numerical solutions are calculated and reveal a richer dynamic for the background, which contains one, two or even three bounce depending on the initial conditions and in the amount of anisotropy.

description: This study examines rape myths and the attribution of blame in instances of rape. This research builds upon previous studies that examined attribution of blame based the effects of gender, attitudes toward rape victims, and race. This study explores the impact of the seriousness of the attack on attributions of blame. It also examines the influence of the level of similarity between the respondent and the victim on attributions of blame. Data was obtained from 408 undergraduate respondents enrolled at a university. Respondents completed an online survey that included the Attitudes Towards Rape Victims Scale and a vignette of a hypothetical rape scenario, with questions following the vignette. This study found that respondents who scored higher on the Attitudes Towards Rape Victims Scale attributed more blame to a victim of rape. Respondent gender was a significant predictor of victim blame at the bivariate level, but not within the multivariate analysis. Whether or not the victim in the vignette had to go to the hospital as a result of the attack, the racial similarity of respondents to the victims, and the social class of the respondents did not significantly influence the attributions of blame. These findings are not consistent with prior research. A discussion of the findings and suggestions for future research are provided.

description: We study the dynamics of an Unruh-DeWitt detector interacting with a massless scalar field in an arbitrary static spherically symmetric spacetimes whose metric is characterised by a single metric function $f(r)$. In order to obtain clean physical insights, we employ the derivative coupling variant of the Unruh-DeWitt model in (1+1) dimensions where powerful conformal techniques enable closed-form expressions for the vacuum two-point functions. Due to the generality of the formalism, we will be able to study a very general class of static spherically symmetric (SSS) background. We pick three examples to illustrate our method: (1) non-singular Hayward black holes, (2) the recently discovered $D\to 4$ limit of Gauss-Bonnet black holes, and (3) the "black bounce" metric that interpolates Schwarzschild black holes and traversable wormholes. We also show that the derivative coupling Wightman function associated with the generalized Hartle-Hawking vacuum satisfies the KMS property with the well-known temperature $f'(r_\text{H})/(4π)$, where $r_\text{H}$ is the horizon radius.

description: We demonstrate a new approach for directly measuring the ultrafast energy transfer between elec- trons and magnons, enabling us to track spin dynamics in an antiferromagnet (AFM). In multiferroic HoMnO3, optical photoexcitation creates hot electrons, after which changes in the spin order are probed with a THz pulse tuned to a magnon resonance. This reveals a photoinduced transparency, which builds up over several picoseconds as the spins heat up due to energy transfer from hot elec- trons via phonons. This spin-lattice thermalization time is ?10 times faster than that of typical ferromagnetic (FM) manganites. We qualitatively explain the fundamental differences in spin-lattice thermalization between FM and AFM systems and apply a Boltzmann equation model for treating AFMs. Our work gives new insight into spin-lattice thermalization in AFMs and demonstrates a new approach for directly monitoring the ultrafast dynamics of spin order in these systems.

description: Bankruptcy prediction of loan applicants is a process of utmost importance for the successful development of financial institutions. The need for managing credit risk has led to the application of many machine learning techniques and classifiers to effectively separate creditworthy from high-risk applicants. However, the large number of proposed models creates a difficulty in choosing the best model. The aforementioned difficulty created the need for model comparison. In the current study, we investigate an alternative approach of model benchmarking. More specifically, we propose the utilization of a multivariate statistical method, known as Archetypal Analysis (AA), which provides an appealing and intuitive approach for the identification of certain reference models and the subsequent benchmarking of all the competitors.

description: For every odd integer $n \geq 3$, we prove that there exist infinitely many number fields of degree $n$ and associated Galois group $S_n$ whose class number is odd. To do so, we study the class groups of families of number fields of degree $n$ whose rings of integers arise as the coordinate rings of the subschemes of $\mathbb{P}^1$ cut out by integral binary $n$-ic forms. By obtaining upper bounds on the mean number of $2$-torsion elements in the class groups of fields in these families, we prove that a positive proportion (tending to $1$ as $n$ tends to $\infty$) of such fields have trivial $2$-torsion subgroup in their class groups and narrow class groups. Conditional on a tail estimate, we also prove the corresponding lower bounds and obtain the exact values of these averages, which are consistent with the heuristics of Cohen-Lenstra-Martinet-Malle and Dummit-Voight. Additionally, for any order $\mathcal{O}_f$ of degree $n$ arising from an integral binary $n$-ic form $f$, we compare the sizes of $\mathrm{Cl}_2(\mathcal{O}_f)$, the $2$-torsion subgroup of ideal classes in $\mathcal{O}_f$, and $\mathcal{I}_2(\mathcal{O}_f)$, the $2$-torsion subgroup of ideals in $\mathcal{O}_f$. For the family of orders arising from integral binary $n$-ic forms and contained in fields with fixed signature $(r_1,r_2)$, we prove that the mean value of the difference $|\mathrm{Cl}_2(\mathcal{O}_f)| - {2^{1-r_1-r_2}}|\mathcal{I}_2(\mathcal{O}_f)|$ is equal to $1$, generalizing a result of Bhargava and the third-named author for cubic fields. Conditional on certain tail estimates, we also prove that the mean value of $|\mathrm{Cl}_2(\mathcal{O}_f)| - {2^{1-r_1-r_2}}|\mathcal{I}_2(\mathcal{O}_f)|$ remains $1$ for certain families obtained by imposing local splitting and maximality conditions.

description: We investigate the structure of metastable states in self-generated Coulomb glasses. In dramatic contrast to disordered electron glasses, we find that these states lack marginal stability. Such absence of marginal stability is reflected by the suppression of the single-particle density of states into an exponentially soft gap of the form $g(ε) \sim e^{-V / ξ|ε|}$. To analytically explain this behavior, we extend the stability criterion of Efros and Shklovskii to incorporate local charge correlations, in qualitative agreement with our numerical findings. Our work suggests the existence of a new class of self-generated glasses dominated by strong geometric frustration.

Cooperation in the Informal Economy: A Study of Day Laborers in North Carolina

Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: The growing number of day labor markets in the United States has provided important insights regarding the inner-workings of the informal economy and lives of thousands of immigrant day laborers. In this paper, I address how social norms emerging from day laborers' interactions and personal beliefs pose challenges to our traditional understanding of competition, which is assumed to shape informal social arenas. Empirical foundations stem from two years of community work, multiple observations, and 20 in-depth interviews with Latino immigrant men at an informal labor-hiring site in Central North Carolina. I use snowball and convenience sampling techniques to select immigrant workers who had been at the site at least three years. Findings illustrate complex human relationships emerging from day laborers' social fabric stemming from economic solidarity, mentorships, wage rigidity, community building, and cultural values, such as luck, which challenge conventional neoclassical economic assumptions related to competition at informal labor markets.

description: The aim of the study was to identify the different types of insertion of the fibular collateral ligament and the biceps femoris muscle into the fibula head, based on the examination of a large number of patients using MRI specific sequences. We searched anatomical and imaging studies into the literature, related to the anatomy of the examined anatomical structures. We referred to the presence of five different subtypes of insertion of the fibular collateral ligament and of the two heads of biceps femoris muscle into the fibular head, as distinct from previous studies, which supported the presence of one common conjoined tendon. We also found out that the predominant type was the presence of the fibular collateral ligament between the anterior and the direct arm of the biceps femoris muscle, with attachment between the ligament and the anterior arm. Furthermore, the type of the common conjoined tendon was the second most common type. The great progress in the image and the quality of MRI, using thin slices, enables anymore the detailed imaging of the subtypes of insertion of the fibular collateral ligament and the biceps femoris muscle, aiming to the early diagnose of confusing old injuries of lateral knee capsular ligaments.

description: Thermal noise generally greatly exceeds quantum noise in optomechanical devices unless the mechanical frequency is very high or the thermodynamic temperature is very low. This paper addresses the design concept for a novel optomechanical device capable of ultrahigh quality factors in the audio frequency band with negligible thermal noise. The proposed system consists of a minimally supported millimeter scale pendulum mounted in a Double End-Mirror Sloshing (DEMS) cavity that is topologically equivalent to a Membrane-in-the-Middle (MIM) cavity. The radiation pressure inside the high-finesse cavity allows for high optical stiffness, cancellation of terms which lead to unwanted negative damping and suppression of quantum radiation pressure noise. We solve for the optical spring dynamics of the system using the Hamiltonian, find the noise spectral density and show that stable optical trapping is possible. We also assess various loss mechanisms, one of the most important being the acceleration loss due to the optical spring. We show that practical devices, starting from a centre-of-mass pendulum frequency of 0.1 Hz, could achieve a maximum quality factor of $10^{14}$ with optical spring stiffened frequency 1-10 kHz. Small resonators of mass 1 $μ$g or less could achieve a Q-factor of $10^{11}$ at a frequency of 100 kHz. Applications for such devices include white light cavities for improvement of gravitational wave detectors, or sensors able to operate near the quantum limit.

description: Intraductal papillary mucinous neoplasms (IPMNs) of the pancreas are cystic tumours located in a central or peripheral position and are in direct communication with the main pancreatic duct or its branches. Indication for surgical treatment is the presence of dysplasia or malignancy. Overall survival depends on the stage they are diagnosed. The surgical treatment consists of either partial or total pancreatectomy, dependant on the location or the presence of malignancy. The type of pancreatectomy should be selected with specific criteria, as it is a procedure of high morbidity and mortality. The oncological outcome should be the main reason for selecting the kind of operation. Although complete pancreatectomy is a satisfactory surgical solution, it impacts the patient’s quality of life. The purpose of this dissertation is the study of indications for surgical treatment of IPMNs in accordance with international guidelines. In addition, presurgical management for detection of possible dysplasia or malignancy, postsurgical outcomes, adjuvant treatments and patient overall survival are studied as well.

description: Quantum criticality is a fundamental organizing principle for studying strongly correlated systems. Nevertheless, understanding quantum critical dynamics at nonzero temperatures is a major challenge of condensed matter physics due to the intricate interplay between quantum and thermal fluctuations. The recent experiments in the quantum spin dimer material TlCuCl$_3$ provide an unprecedented opportunity to test the theories of quantum criticality. We investigate the nonzero temperature quantum critical spin dynamics by employing an effective $O(N)$ field theory. The on-shell mass and the damping rate of quantum critical spin excitations as functions of temperature are calculated based on the renormalized coupling strength, which are in excellent agreements with experiment observations. Their $T\ln T$ dependence is predicted to be dominant at very low temperatures, which is to be tested in future experiments. Our work provides confidence that quantum criticality as a theoretical framework, being considered in so many different contexts of condensed matter physics and beyond, is indeed grounded in materials and experiments accurately. It is also expected to motivate further experimental investigations on the applicability of the field theory to related quantum critical systems.

description: The United States Army Special Forces is an unconventional warfare organization of the United States Army with roots in World War II. Soldiers and civilian policymakers who participated in guerilla warfare during that war saw unconventional warfare as a way to further American interests in situations where a conventional army could not operate effectively. In the postwar national security policy battles, these soldiers and government officials fought for a permanent unconventional warfare unit in the US Army. By 1951 They had successfully argued for the establishment of Army Special Forces Groups utilizing guerilla warfare to fight Soviet Communism in the event of a general war. The problems of understanding and defining unconventional warfare, however, crippled the ability of Army Special Forces to instigate guerilla warfare against the Soviet Union wherever and whenever needed.

description: A three-dimensional numerical simulation is conducted for a complex process in a laser-material system, which involves heat and mass transfer in a compressible gaseous phase and chemical reaction during laser irradiation on a urethane paint coated on a stainless steel substrate. A finite volume method (FVM) with a co-located grid mesh that discretizes the entire computational domain is employed to simulate the heating process. The results show that when the top surface of the paint reaches a threshold temperature of 560 K, the polyurethane starts to decompose through chemical reaction. As a result, combustion products CO2, H2O and NO2 are produced and chromium (III) oxide, which serves as pigment in the paint, is ejected as solid parcels from the paint into the gaseous domain. Variations of temperature, density and velocity at the center of the laser irradiation spot, and the concentrations of reaction reactant/products in the gaseous phase are presented and discussed, by comparing six scenarios with different laser powers ranging from 2.5 kW to 15 kW with an increment of 2.5 kW.

Στο πλαίσιο αυτό προσεγγίσαμε θεωρητικά την προστασία του καταναλωτή στη βάση του εθνικού και ενωσιακού δικαίου. Ειδικότερα, μέσα από τις διατάξεις της νομοθεσίας, μεταξύ άλλων, περιλάβαμε ορισμούς, αποσαφηνίσαμε τα δικαιώματα και τις υποχρεώσεις των αντισυμβαλλόμενων μερών, παραθέσαμε εργαλεία-μέσα που έχει στη διάθεσή του ο καταναλωτής στην περίπτωση που προκύπτει διαφορά με τον προμηθευτή, καθώς και τροποποιήσεις που επέφερε η Οδηγία 2019/2161/ΕΕ για την ενίσχυση της επιβολής της νομοθεσίας της Ευρωπαϊκής Ένωσης και τον εκσυγχρονισμό των ενωσιακών κανόνων για την προστασία των καταναλωτών ενόψει των εξελίξεων της αγοράς.
description: The aim of the present thesis was the study of the consumer protection rules as they have been formed after the New Deal for Consumers. We focused on Consumer Law exclusively in distance contracts, where the use of digital media today, especially due to the emergence of the coronavirus pandemic, has become almost a unique option, which has as a result that the consumers-users of these media face new challenges about their rights and obligations. In this context, we approached theoretically consumer protection on the basis of national and European Union law. In particular, through the provisions of the legislation, among other things, we included definitions, we clarified the rights and obligations of the contracting parties, we mentioned tools-means that are available to the consumers in case of a dispute with the supplier, as well as amendments brought by the Directive 2019/2161/EU about strengthening enforcement of the European Union law and modernizing EU consumer protection rules in view of market developments.

description: We study the supersymmetric partition function of 4d supersymmetric gauge theories with a U(1) R-symmetry on Euclidean $S^3\times S_β^1$, with $S^3$ the unit-radius squashed three-sphere, and $β$ the circumference of the circle. For superconformal theories, this partition function coincides (up to a Casimir energy factor) with the 4d superconformal index. The partition function can be computed exactly using supersymmetric localization of the gauge theory path-integral. It takes the form of an elliptic hypergeometric integral, which may be viewed as a matrix-integral over the moduli space of the holonomies of the gauge fields around $S_β^1$. At high temperatures ($β\to 0$, corresponding to the hyperbolic limit of the elliptic hypergeometric integral) we obtain from the matrix-integral a quantum effective potential for the holonomies. The effective potential is proportional to the temperature. Therefore the high-temperature limit further localizes the matrix-integral to the locus of the minima of the potential. If the effective potential is positive semi-definite, the leading high-temperature asymptotics of the partition function is given by the formula of Di Pietro and Komargodski, and the subleading asymptotics is connected to the Coulomb branch dynamics on $R^3\times S^1$. In theories where the effective potential is not positive semi-definite, the Di Pietro-Komargodski formula needs to be modified. In particular, this modification occurs in the SU(2) theory of Intriligator-Seiberg-Shenker, and the SO(N) theory of Brodie-Cho-Intriligator, both believed to exhibit "misleading" anomaly matchings, and both believed to yield interacting superconformal field theories with $c

title: Explorative Untersuchung der Wirksamkeit des Eltern Stärken Programms
Creators: name: Chabbouh, Mona
Year: 2022

description: Die Bedeutung der Erziehungskompetenz der Eltern für die Entwicklung der Kinder ist unbestritten. Dabei stellt der Begriff Erziehungskompetenz ein multidimensionales Konstrukt dar, das in der vorliegenden Untersuchung sowohl konkretes dysfunktionales Erziehungsverhalten als auch Aspekte der Wahrnehmung in der Elternrolle einschließt. Vor dem Hintergrund der spezifischen Belastungen von Familien mit Flucht- und Migrationshintergrund kommt der kultursensiblen Förderung der Erziehungskompetenz eine besondere Bedeutung zu. Im Rahmen einer Anwendungsforschung wurde das Eltern Stärken Programm des Vereins AFYA erforscht: Effekte der Teilnahme an diesem Programm wurden explorativ untersucht. Insgesamt nahmen zehn Teilnehmer*innen zu drei Zeitpunkten an der Erhebung teil: direkt vor Beginn des Programms, nach Ende des Programms, und 2 bis 8 Wochen nach Ende des Programms. Außerdem widmete sich eine Nebenuntersuchung der Informationsgewinnung zur Umsetzung des Programms. Diese wurde mittels Expert*innen-Interviews mit vier Trainer*innen des Programms durchgeführt. Trotz erheblicher Limitationen wurden Hypothesen zur Wirksamkeit des Programms formuliert. Praxisnahe Empfehlungen für eine weitere Evaluation dieses gesellschaftlich relevante Programm wurden eingeführt.
title: Wenn sich die Eltern erwachsener Kinder scheiden lassen
Creators: name: Loibel, Laura
Year: 2022

description: In der vorliegenden Masterarbeit wurde das Erleben einer Trennung oder Scheidung der Eltern im Erwachsenenalter untersucht. Das Forschungsinteresse lag zudem auf den entwickelten Handlungsstrategien der erwachsenen Kinder im Umgang mit der elterlichen Trennung oder Scheidung. Dazu wurden zehn problemzentrierte Interviews mit Personen geführt, die eine Trennung oder Scheidung der Eltern in den letzten ein bis fünf Jahren, als sie bereits 18 Jahre oder älter waren und nicht mehr mit ihren Eltern im selben Haushalt wohnten, erlebt haben. Die Interviews wurden mithilfe des Kodierverfahrens der Grounded Theory ausgewertet. Als theoretische Grundlage dienten die Divorce-Stress-Adjustment Perspektive, sowie die Uncertainty Management Theorie und das Divorce-Disclosure Modell. Die Ergebnisse zeigen, dass erwachsene Kinder durch eine elterliche Trennung oder Scheidung mit Herausforderungen konfrontiert sind. Die Befragten erlebten durch die Auflösung der Ehe oder Partnerschaft der Eltern Veränderungen bekannter Strukturen, die Anpassungsleistungen von ihnen erforderten. Beim Erleben der elterlichen Trennung legten die Befragten einen Fokus auf das Wohlbefinden ihrer Familienmitglieder. Von Bedeutung für das Erleben der Kinder war außerdem das Verhalten ihrer Eltern im Umgang mit der elterlichen Trennung. Die Kommunikation und Information über die Trennung oder Scheidung stellte sich als relevant heraus und konnte sich vor allem negativ auf ihr Erleben der elterlichen Trennung auswirken. Die Befragten sahen trotz damit einhergehender Herausforderungen auch positive Aspekte der elterlichen Trennung oder Scheidung und empfanden sie daher grundsätzlich nicht negativ. Die von den Befragten entwickelten Handlungsstrategien (1) das Positive sehen, (2) Abstand suchen, (3) Unterstützung suchen, annehmen und anbieten, (4) Konfrontation und Grenzen aufzeigen, (5) Neutralität und (6) Akzeptanz, Gewöhnung und Anpassung, ermöglichten den Befragten einen besseren Umgang mit der elterlichen Trennung.

description: The discrete tori are graph analogues of the real tori, which are defined by the Cayley graphs of a finite product of finite cyclic groups. In this paper, using the theory of the heat kernel on the discrete tori established by Chinta, Jorgenson and Karlsson, we derive an explicit prime geodesic theorem for the discrete tori, which is not an asymptotic formula. To describe the formula, we need generalizations of the classical Jacobi polynomials, which are defined by the Lauricella multivariable hypergeometric function of type C.

PROBABILISTIC HURRICANE TRACK GENERATION FOR STORM SURGE PREDICTION
Creators: name: Smith, Jessica

description: Storm surge is a major source of devastation from hurricane events, and as such it is important to understand the uncertainty associated with storm surge forecasting. Uncertainty in predicted storm surge can be quantified by synthesizing a suite of probable storm tracks that are based on errors in predictions of previous hurricanes and computing storm surge with a suitable model. Davis et al. (2010) developed an approach to track generation based on cross-track errors in the official National Hurricane Center (NHC) forecast tracks. In this work their methods are extended to include along-track and maximum wind speed errors. Errors in the NHC forecasts are used to compute probability distributions that are sampled to generate synthetic tracks on either side of the official forecast track, with each track having an equal likelihood of occurrence. Storm surge for each track is then computed with the ADCIRC model (Westerink et al., 2008) to generate probability of exceedance maps and worst-case potential storm surge (maximum of maximums). The ideal error distribution sampling number for the forecast experiments used in this study for each dimension are 27 in the cross-track dimension, 9 in the along-track dimension, and 9 in the intensity dimension.
An Intersectional Decolonial Feminist Critique of Kant

Publisher: name: University of Illinois at Chicago

description: In this dissertation, I put forth a critique of Kant’s account of womanhood to show the morally significant exclusions and erasures of non-white women in his moral theory. In Chapter 1, I argue that we need new methodological approaches to tackle the issues of racism and sexism in Kant. Following Dilek Huseyinzadegan, I lay out my methodology of constructive complicity which entails taking all of Kant’s works as relevant to our scholarship and our lives, placing Kant in the dark side of the Enlightenment, borrowing tools from US based Black feminists and Decolonial feminists, and grounding my orientation towards Kant in these traditions (their commitments and values). In Chapter 2, I review some of the literature on Kant’s racism, sexism, and heterosexism. I show that the pervasive lack of intersectional analyses and the prioritization of Kant’s ideal theory over his non-ideal theory has prevented us from seeing the depth and complexity of racist and sexist exclusions in Kant’s moral theory. In Chapter 3, I ask bell hooks’ question “Which women?” and trace the metalanguage of race (Evelyn Brooks Higginbotham) in Kant’s discussion of womanhood and civilization. I argue that Kant’s account of womanhood is implicitly white and that it renders non-white women (and their kin) incapable of participating in moral development. Lastly, I argue that we need Kant’s racist-sexist anthropological account to determine whom the Categorical Imperative’s Formula of Humanity applies to, showing that the former cannot be neatly excised from the latter. In Chapter 4, I argue that the mainstream approach to teaching Kant’s moral theory results in epistemic harms whereby minoritized students are asked to disembody and abandon their racialized, gendered, and sexualized positionalities and see themselves as unproblematically included in Kant’s moral theory. I suggest that we need to teach Kant in radically different ways to reduce or avoid these harms, and I offer Maria Lugones’ decolonial feminist account of ‘world’-travel as a promising approach

description: Sunquakes are the surface signatures of acoustic waves in the Sun's interior that are produced by some but not all flares and coronal mass ejections (CMEs). This paper explores a mechanism for sunquake generation by the magnetic field changes that occur during flares and CMEs, using MHD simulations with a semiempirical FAL-C atmosphere to demonstrate the generation of acoustic waves in the interior in response to changing magnetic tilt in the corona. We find that Alfven-sound resonance combined with the ponderomotive force produces acoustic waves in the interior with sufficient energy to match sunquake observations when the magnetic field angle changes by the order of 10 degrees in a region where the coronal field strength is a few hundred gauss or more. The most energetic sunquakes are produced when the coronal field is strong, while the variation of magnetic field strength with height and the time scale of the tilt change are of secondary importance.

description: [Français] Ce travail s’inscrit dans la continuité de la recherche commencé lors de mon année de Master 1, qui portait sur l’intégration des pratiques et espaces de jeux d’argent au monde urbain, à travers l’étude de cas du VIIe arrondissement de Paris. Au cours de ce travail au cœur d’un des arrondissements les plus huppés de la capitale, j’ai pu comme d’autre avant moi constater que les jeux d'argent et de hasard attirent une importante clientèle d’origine étrangère (Mangel, 2006 ; Marsaud, 2004 ; Martignoni-Hutin & Henriot, 1993) et ainsi m’interroger sur le lien entre les populations immigrés et les jeux d’argent. Ce précédent travail m’a aussi amené à me questionner sur le rôle et l’impact des lieux de jeux d’argent, tels que les points de ventes de la Française des jeux (FDJ) et du Pari mutuel urbain (PMU) sur les dynamiques urbaines. Comme le montre de récent travaux en géographie (Berroir et al., 2015 ; Fleury & Fol, 2018 ; Fleury & Mayadoux, 2019 ; Gholami Saba & Fleury, 2020), le tissu commercial d’un quartier ou d’une localité et son évolution dans le temps donnent à voir les dynamiques urbaines en cours au cœur de ces quartiers en lien avec les politiques urbaines mises en place par les pouvoirs publics à différentes échelles. Dans ce présent travail de recherche, nous chercherons ainsi à déterminer comment la pratique des jeux d’argent peut être révélatrice de processus urbain à l’œuvre à Aubervilliers. [English] This project is a continuation of the research I started during my first year of the Master's programme, which focused on the integration of gambling practices and spaces in the urban world, through the case study of the 7th arrondissement of Paris. During this research in the heart of one of the capital's most exclusive districts, I was able to observe, as others have done, that gambling attracts a large foreign clientele (Mangel, 2006; Marsaud, 2004; Martignoni-Hutin & Henriot, 1993) and thus to question the link between immigrant populations and gambling. This previous work also led me to question the role and impact of gambling venues, such as FDJ and PMU sales outlets, on urban dynamics. As recent research in geography has shown (Berroir et al., 2015; Fleury & Fol, 2018; Fleury & Mayadoux, 2019; Gholami Saba & Fleury, 2020), the commercial environment of a district or locality and its evolution over time reveal the urban dynamics at the heart of these districts in relation to the urban policies put in place by the public authorities at different levels. In this research, we will try to determine how the practice of gambling can be indicative of the urban process at work in Aubervilliers.

description: This paper is a creative text based on intensive ethnographic fieldwork and critical ideas encountered in secondary research. It tells the story of an elderly widow, Sandy Edgerly, through her objects. It focuses on four objects that each represents a moment of transformation in Sandy's life. Through these four objects a biography materializes that can be seen as an epitome of how individuals map and navigate life through stories attached to transitional moments. This work is located at the intersection where material culture, ethnography, and performance theory meet to explore the question of identity.
