Intra-European migration and identity : the case study of Germans living in the South-East of England.
Creators: name: Wlasny, Miriam
Publisher: name: University of Surrey
Year: 2020

description: Capturing a snapshot of around the time of the 2015 general election, this research explored the motivations, experiences and thoughts of Germans living in the South-East of England regarding their decision to migrate and settle in the country. As lifestyle migrants, their motivations for moving to the UK – rather than being predominantly economic – are constitutive of an individualised pursuit of ‘a better life’. Employment and education related reasons were as common among participants as personal life motivations like being with a loved one, and, likewise, a desire to experience life in a different culture. Their accounts of settling in the new environment are largely absent of serious difficulties, which is mostly due the cultural proximity of country of origin and destination, as well as the relatively high level of secondary (and in some cases tertiary) education they benefitted from before embarking on their migratory journey to the UK. Respondents displayed a strong desire to learn the ‘British way of life’ and blend in as much as they could by letting go of German habits and by purposefully not seeking out or associating with co-ethnics. Their ability to do so is attributed to their white, Western European privilege that provided them with the ‘capital’ to be able to visually blend in and have the necessary language skills not to depend on co-ethnics. Due to a perceived stigmatised national identity and a strong sense of unease regarding the ‘slippery slope’ of patriotism, most respondents identified more with transnational and local sources of identity rather than national ones. While this tendency is likely to stem from their nation’s Nazi-past, their thoughts, convictions and self-reported behaviours suggest that they can be understood as part of a (possibly) relatively small, but symbolically significant emerging European civic culture facilitated by the European project of integration.

description: Mid-infrared (MIR) spectroscopy is widely recognized as a powerful, non-distractive method for chemical analysis. However, its utility is constrained by a micrometer-scale spatial resolution imposed by the long-wavelength MIR diffraction limit. This limitation has been recently overcome by MIR photothermal (MIP) imaging, which detects photothermal effects induced in the vicinity of MIR absorbers using a visible-light microscope. Despite its promise, the full potential of its spatial resolving power has not been realized. Here, we present an optimal implementation of wide-field MIP imaging to achieve high spatial resolution. This is accomplished by employing single-objective synthetic-aperture quantitative phase imaging (SOSA-QPI) with synchronized sub-nanosecond MIR and visible light sources, effectively suppressing the resolution-degradation effect caused by photothermal heat diffusion. We demonstrate far-field MIR spectroscopic imaging with a spatial resolution limited by the visible diffraction, down to 125 nm, in the MIR region of 3.12-3.85 um (2,600-3,200 cm-1). This technique, through the use of a shorter visible wavelength and/or a higher objective numerical aperture, holds the potential to achieve a spatial resolution of less than 100 nm, thus paving the way for MIR wide-field nanoscopy.
La reconnaissance des musulmans en contexte de laïcité : médiation et dialogue chez Mohammed Arkoun et Tariq Ramadan

description: Certaines demandes de reconnaissance formulées par les musulmans sont parfois perçues comme autant de potentielles atteintes à la neutralité des États qui se veulent laïcs. Face à une population de plus en plus diversifiée sur les plans religieux et culturels, ces États doivent-ils repenser la place à aménager à cette diversité grandissante et parfois déconcertante? La religion musulmane encourage-t-elle une confusion des pouvoirs temporels et spirituels au point qu’il serait impossible pour un musulman de pratiquer son culte dans un contexte laïc? Rejetant cette dernière hypothèse, qu’il attribue à une interprétation désuète de l’islam, Tariq Ramadan affirme qu'il est tout à fait possible d'être à la fois un musulman fidèle et un bon citoyen européen ou nord américain. De son côté, Mohammed Arkoun (2007) considère que cette confusion n’est pas de nature théologique, elle est plutôt le résultat du travail de l’histoire. Ramadan et Arkoun proposent chacun une pensée reliant islam et laïcité. Quelle est la contribution de ces penseurs dans le cadre des conflits entourant les demandes de reconnaissance des musulmans dans un contexte laïc? Afin de penser le dialogue démocratique dans des sociétés contemporaines de plus en plus caractérisées par une « étrange multiplicité », James Tully (1999) s’inspire de L’Esprit de Haïda Gwaii, une œuvre du sculpteur haïda Bill Reid. Au milieu d’un canot, avec à son bord un équipage hétéroclite, se trouve le Chef (conçu comme un médiateur) qui prête une oreille attentive aux perspectives des uns et des autres. Par le biais de cette métaphore, Tully suggère un type d’accord constitutionnel respectueux des aspirations de chacun, tant à la liberté critique qu’à l’appartenance. Inspirée par le travail de Tully et guidée par des principes herméneutiques tirés de la pensée de Gadamer, cette thèse propose d’approfondir l’analyse du rôle et de la contribution du médiateur. Ainsi, ce travail s’articule autour de l’hypothèse suivante : Soucieux d’apaiser ces conflits, le médiateur agit comme un critique social. Il propose de repenser le rapport entre islam et laïcité et cherche à faciliter le dialogue entre les parties en conflit. Dans ces circonstances, les notions de « subversion » et de « réforme » respectives à Arkoun et Ramadan incarnent toutes deux une pensée de la médiation. Cependant, la réforme de Ramadan s’appuie davantage sur la dimension de l’appartenance (médiation identitaire), tandis que la subversion chez Arkoun fait davantage appel à la liberté critique (médiation critique).

description: Anisotropy plays a key role in science and engineering. However, the interplay between the material and engineered photonic anisotropies has hardly been explored due to the vastly different length scales. Here we demonstrate a matter-light hybrid system, exciton-polaritons in a 2D antiferromagnet, CrSBr, coupled with an anisotropic photonic crystal (PC) cavity, where the spin, atomic lattice, and photonic lattices anisotropies are strongly correlated, giving rise to unusual properties of the hybrid system and new possibilities of tuning. We show exceptionally strong coupling between engineered anisotropic optical modes and anisotropic excitons in CrSBr, which is stable against excitation densities a few orders of magnitude higher than polaritons in isotropic materials. Moreover, the polaritons feature a highly anisotropic polarization tunable by tens of degrees by controlling the matter-light coupling via, for instance, spatial alignment between the material and photonic lattices, magnetic field, temperature, cavity detuning and cavity quality-factors. The demonstrated system provides a prototype where atomic- and photonic-scale orders strongly couple, opening opportunities of photonic engineering of quantum materials and novel photonic devices, such as compact, on-chip polarized light source and polariton laser.

description: Mining operations in remote locations rely heavily on diesel fuel for the electricity, haulage and heating demands. Such significant diesel dependency imposes large carbon footprints to these mines. Consequently, mining companies are looking for better energy strategies to lower their carbon footprints. Renewable energies can relieve this over-reliance on fossil fuels. Yet, in spite of their many advantages, renewable systems deployment on a large scale has been very limited, mainly due to the high battery storage system. Using hydrogen for energy storage purposes due to its relatively cheaper technology can facilitate the application of renewable energies in the mining industry. Such cost-prohibitive issues prevent achieving 100% penetration rate of renewables in mining applications. This paper offers a novel integrated renewable–multi-storage (wind turbine/battery/fuel cell/thermal storage) solution with six different configurations to secure 100% off-grid mining power supply as a stand-alone system. A detailed comparison between the proposed configurations is presented with recommendations for implementation. A parametric study is also performed, identifying the effect of different parameters (i.e., wind speed, battery market price, and fuel cell market price) on economics of the system. The result of the present study reveals that standalone renewable energy deployment in mine settings is technically and economically feasible with the current market prices, depending on the average wind speed at the mine location.

Upregulation of Innate Immunity in the Tumour Microenvironment of Oesophageal Adenocarcinoma

Publisher: name: University of Surrey
Year: 2023

description: Oesophageal cancer – of which adenocarcinoma (OAC) is the predominant type in the UK - is a highly aggressive malignancy, with 5-year survival rates of approximately 15%. Surgically resectable disease is treated with perioperative chemo+/-radiotherapy. Neoadjuvant chemoradiotherapy is known to improve survival, mechanistically this may occur through the induction of an anti-tumour immune response within the tumour microenvironment (TME). While chemoradiotherapy may modulate the TME towards tumour rejection, they are unselective treatments with significant systemic toxicity. Hence novel approaches to the treatment of OAC are required. Immunotherapy has achieved more precise immunomodulation with delivery of biological agents in several cancers including OAC. Most immunotherapy trials in OAC have looked at utilising immune checkpoint blockade (ICB), alone or in combination with standard treatments. Intratumoural delivery of immunotherapy provides an innovative option in the treatment paradigm, using the cancer as a vaccine against itself. The ideal combination intratumoural immunotherapy starts with a stress on the tumour, such as an oncolytic virus (OV) that triggers immunogenic cell death (ICD) followed by secondary agents that enhance antigen presentation and the activation of effector immune cells.

description:

description: This Medical Research Council funded PhD has used bioinformatic analysis of the TCGA-ESCA database in combination with nine-colour multispectral immunohistochemistry, performed on a local cohort of treatment naïve OAC tumours, to gain insights into the immune tumour microenvironment of OAC, with a specific focus on the activity of natural killer and dendritic cells. Then using two 3D ex vivo tumour modelling techniques, organotypic slice culture and tumour organoids, the ability for an oncolytic HSV-1 to selectively infect, replicate within and then kill tumour tissue has been assessed. Following this the development of a novel subcutaneous immunocompetent mouse model of OAC has been successfully achieved, allowing for assessment of our combination of oncolytic virus and immunotherapies in vivo.

description: We present the Simple Intensity Map Producer for Line Emission (SIMPLE), a public code for quickly simulating mock line-intensity maps, and an analytical framework for modeling intensity maps including observational effects. SIMPLE can be applied to any spectral line sourced by galaxies. The SIMPLE code is based on lognormal mock catalogs of galaxies including positions and velocities and assigns luminosities following the luminosity function. After applying a selection function to distinguish between detected and undetected galaxies, the code generates an intensity map, which can be modified with anisotropic smoothing, noise, a mask, and sky subtraction, and calculates the power spectrum multipoles. We show that the intensity autopower spectrum and the galaxy-intensity cross-power spectrum agree well with the analytical estimates in real space. We derive and show that the sky subtraction suppresses the intensity autopower spectrum and the cross-power spectrum on scales larger than the size of an individual observation. As an example application, we make forecasts for the sensitivity of an intensity mapping experiment similar to the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) to the cross-power spectrum of Ly$α$-emitting galaxies and the Ly$α$ intensity. We predict that HETDEX will detect the galaxy-intensity cross-power spectrum on scales of $0.04\, h\,\mathrm{Mpc}^{-1} < k < 1\, h\,\mathrm{Mpc}^{-1}$.

description: Two-dimensional van der Waals materials have recently been established experimentally as a highly-tunable condensed matter platform, facilitating the controlled manipulation of band structures and interactions. In several of these materials, Dirac cones are present in the low-energy regime near the Fermi level. Thus, fermionic excitations emerging in these materials close to the Dirac cones have a linear dispersion relation near the Fermi surface as massless relativistic Dirac fermions. Here, we study low-energy fermionic excitations of such Dirac materials in the presence of a mass gap that may be generated by symmetry breaking. Introducing a dynamical Fermi velocity and/or time-dependent mass gap for the Dirac quasiparticles, we exhibit the emergence of an analog of cosmological fermion pair production in terms of observables such as the expected occupation number or two-point correlation functions. We find that it is necessary and sufficient for quasiparticle production that only the ratio between the mass gap and the Fermi velocity is time-dependent. In this way, we establish that highly-tunable Dirac materials can serve as analog models for cosmological spacetime geometries, in particular, for Friedmann-Lemaître-Robertson-Walker expanding cosmologies. We briefly discuss possibilities for experimental realization

description: In recent years, the number of asylum seekers and refugees in the UK has been increasing. Given the nature of their forced migration and current hostile policies inimical to their wellbeing, a proportion of these individuals will require support from statutory mental health services, including but not limited to psychological intervention. Asylum seekers and refugees may present with a number of complex needs to services, although services may struggle to engage with these needs or fully understand them. Consequently, this doctoral thesis aimed to add to the literature around issues of both understanding and engaging refugee and asylum seeker clients.

description: Part one of this portfolio aims to synthesise a variety of literature concerning unaccompanied asylum-seeking children (UASC) to better understand their needs. The paper uses the power threat meaning framework (PTMF) to do this and argues for its utility in providing integrative and holistic understanding of these vulnerable young people as a helpful alternative to psychiatric diagnosis. Paper two presents a qualitative empirical paper that investigated the experiences of practitioner psychologists in building trusting therapeutic relationships with asylum-seekers and refugees. Using interpretative phenomenological analysis, the findings suggested that psychologists were required to engage in various types of extra-therapeutic work, both inside and outside the therapy room, to differentiate themselves from their clients’ negative experiences of the past. However, the degree to which these tasks could be performed were limited by the service structures they worked within.

description: Based on a hybrid light-matter unitary transformation for cavity quantum electrodynamics, we investigate the spectral shift of an atom induced by quantum fluctuations in a chiral vacuum cavity. Remarkably, we find an intriguing angular momentum-dependent shift in the spectra of bound states. Our approach shows promise in going beyond traditional perturbative methods and demonstrates effectiveness even in the strong-coupling limit, as evidenced by our numerical benchmarks in the case of a two-dimensional quantum harmonic oscillator. In addition, we establish a cavity-interaction picture for calculating the chiral vacuum Rabi oscillation in the strong-coupling limit for a generic central potential. The anomalous spectral shift revealed in this study possesses both fundamental and practical significance and could be readily observed in experiments.

Discrimination et reconnaissance des expressions faciales émotionnelles chez l’enfant

description: Les expressions de peur et de dégoût sont reconnues plus tardivement et avec plus de difficulté que les autres expressions émotionnelles. Bien que plusieurs auteurs se soient penchés sur la reconnaissance des expressions faciales, peu d’études ont examiné spécifiquement le décodage de ces expressions. Dans le cadre de cette thèse, nous nous sommes intéressés au développement du décodage de ces expressions, en considérant deux aspects complémentaires: la discrimination visuelle et la reconnaissance. Ces derniers furent évalués à l’aide d’une série de trois études, utilisant des représentations photographiques d’expressions faciales ainsi que des méthodes sollicitant peu les habiletés verbales. Nos résultats de la première étude indiquent que les enfants de 10 ans reconnaissent mieux les expressions faciales de peur et de dégoût que ceux de cinq ans. Toutefois, cette différence se limitait à des contrastes spécifiques : dégoût-colère, peur-surprise et peur-tristesse. Les résultats de la seconde étude montrent que les expressions de peur et de dégoût sont très bien discriminées sur le plan visuel des autres expressions dès l’âge de 5 ans. Certains gains de performance furent observés entre cinq et 10 ans, mais ils étaient modestes comparativement à ceux de la première étude. Les enfants avaient plus de difficulté à distinguer entre les expressions de dégoût et de colère qu’entre les expressions de dégoût et celles de tristesse, peur et surprise Les résultats de la troisième étude indiquent que, dès 5 ans, les enfants sont capables de reconnaître la peur à partir de combinaisons d’unités d’action localisées dans la région des yeux ou de la bouche. De plus, ils montrent qu’ils parvenaient à reconnaître le dégoût à partir d’une seule unité d’action située dans la partie centrale du visage (nose wrinkler). Les combinaisons d’unités d’actions de la peur qui étaient situées dans la région des yeux avaient plus tendance à être confondues avec celles de surprise, comparativement à celle situées dans la région de la bouche.

description: The recent discovery of the Weyl semimetal CeAlSi with simultaneous breaking of inversion and time-reversal symmetries has opened up new avenues for research into the interaction between light and topologically protected bands. In this work, we present a comprehensive examination of the shift current and injection current responsible for the circular photogalvanic effect in CeAlSi using first-principles calculations. Our investigation identifies a significant injection current of 4 mA/V$^2$ over a broad range in the near-infrared region of the electromagnetic spectrum, exceeding previously reported findings. In addition, we explored several externally controllable parameters to further enhance the photocurrent. A substantial boost in the injection current is observed when applying uniaxial strain along the $c$ axis of the crystal: a 5% strain results in a remarkable 64% increment. The exceptional photocurrent response in CeAlSi suggests that magnetic non-centrosymmetric Weyl semimetals may provide promising opportunities for novel photogalvanic applications.

description: We study the determination of functions in Fock space from samples of their absolute value, known as the phase retrieval problem in Fock space. An important finding in this research field asserts that phaseless sampling on lattices of arbitrary density renders the problem unsolvable. The present study establishes solvability when using irregular sampling sets of the form $A \cup B \cup C$, where $A, B,$ and $C$ constitute perturbations of a Liouville set, i.e., a set with the property that all functions in Fock space bounded on the set are constant. The sets $A, B,$ and $C$ adhere to specific geometrical conditions of closeness and noncollinearity. We show that these conditions are sufficiently generic so as to allow the perturbations to be chosen also at random. By proving that Liouville sets occupy an intermediate position between sets of stable sampling and sets of uniqueness, we obtain the first construction of uniqueness sets for the phase retrieval problem in Fock space having a finite density. The established results apply to the Gabor phase retrieval problem in subspaces of $L^2(\mathbb{R})$, where we derive additional reductions of the size of uniqueness sets: for the class of real-valued functions, uniqueness is achieved from two perturbed lattices; for the class of even real-valued functions, a single perturbation suffices, resulting in a separated set.

Reproductive function in women aged 18-45 years following Bariatric Surgery
Creators: name: Attersley-Smith, Stephanie Harriet
Publisher: name: University of Surrey
Year: 2023

description: Obesity has a negative impact on multiple aspects of female reproductive function. Bariatric surgery is increasingly being used to address obesity and its health sequelae that do not respond to diet and lifestyle modification. Women of reproductive age comprise a large proportion of those undergoing surgery. The impact of bariatric surgery on female reproductive function (i.e. both implied fertility potential and demonstrated fertility through pregnancy rates) has yet to be conclusively established.

description:

description: This study aims to address this gap in the knowledge base by recruiting women aged between 18-45 years prior to bariatric surgery and following their progress for twenty-four months after surgery to observe any improvements in reproductive function. Multiple methods were used to assess the various aspects of reproductive function; questionnaires captured data on menstrual frequency, clinical hirsutism, contraception use, pregnancy rates and sexual quality of life, biochemical testing measured sex hormone binding globulin, total testosterone (allowing free androgen index to be calculated) and anti-mullerian hormone (a marker of ovarian reserve) and ultrasound was used for ovarian imaging. Any changes in these components of reproductive function were then correlated with the type of surgery and degree of weight loss/normalisation. A separate control group of women living with obesity who continued to have obesity during follow-up was included for anti-mullerian hormone.

description:

description: All aspects of reproductive function measured within the study showed improvements post-surgery. The burden of polycyclic ovarian syndrome reduced from 35% (n=35) of the surgical cohort at baseline to 7% (n=3) at twenty-four months follow-up. Improvements in androgen profile and menstrual frequency were observed in all women irrespective of diagnosis of polycystic ovarian syndrome. Ovarian volume significantly reduced following surgery in the subgroup of women with polycystic ovarian syndrome. Over the course of follow-up anti-mullerian hormone remained stable in the control and surgical group without polycystic ovarian syndrome, but fell in the surgical group with this diagnosis (likely reflecting the improvement in/resolution of the condition). Sexual quality of life showed a modest sustained improvement in the surgical cohort at twenty-four months. None of the changes observed were related to procedure type.

description: Although uncertainties persist, this study supports that weight loss secondary to bariatric surgery can provide improvements in a wide range of elements of female reproductive function.

description: Cost-efficient and easily integrable broadband mid-infrared (mid-IR) sources would significantly enhance the application space of photonic integrated circuits (PICs). Thermal incandescent sources are superior to other common mid-IR emitters based on semiconductor materials in terms of PIC compatibility, manufacturing costs, and bandwidth. Ideal thermal emitters would radiate directly into the desired modes of the PIC waveguides via near-field coupling and would be stable at very high temperatures. Graphene is a semi-metallic two-dimensional material with comparable emissivity to thin metallic thermal emitters. It allows maximum coupling into waveguides by placing it directly into their evanescent fields. Here, we demonstrate graphene mid-IR emitters integrated with photonic waveguides that couple directly into the fundamental mode of silicon waveguides designed for a wavelength of 4,2 μm relevant for CO${_2}$ sensing. High broadband emission intensity is observed at the waveguide-integrated graphene emitter. The emission at the output grating couplers confirms successful coupling into the waveguide mode. Thermal simulations predict emitter temperatures up to 1000°C, where the blackbody radiation covers the mid-IR region. A coupling efficiency η, defined as the light emitted into the waveguide divided by the total emission, of up to 68% is estimated, superior to data published for other waveguide-integrated emitters.

description: Safety is major concern for organisations, and research has shown that individual differences have important roles in determining safety related behaviours. However, there are still substantial gaps in the literature that could further understanding of why individuals behave unsafely. Research in the safety literature has been constricted by the conceptualisation of personality as a stable construct and by research methods that usually measure personality and safety behaviours in their broad forms. Furthermore, there is little research on other influential individual differences, such as intentions and decision-making processes, that may affect the relationship between personality and safety behaviours.
description: This thesis by publication aims to fill these gaps with three research papers on how personality and decision-making affects safety related behaviours. The first paper is a meta- analysis that examines relationships between the Big Five traits and specific safety related behaviours, such as rule violations, aggressive acts and compliance. It also examines personality facets, and traits not classified in the Big Five, and their effect on unsafe behaviour. Two observations were made during data collection of the meta-analysis: there were very few studies that researched the effect of decision-making processes on safety behaviours and no safety studies conceptualised personality as changeable, dynamic and reactive to workplace situations. Thus, the second paper constructed a safety decision making scale to make it possible for future researchers to test for relationships between safety decision making and behaviours. Finally, the third paper is a conceptual review that transfers knowledge of personality dynamics to the safety literature, to explain why individuals vary in their risk taking across different domains of risk, such as safety. The overall thesis contributes to the safety literature by providing depth in the exploration of personality and safety relationships, and by applying different perspectives of personality and decision making to explain safety related behaviours.

description: We study the determination of a holomorphic function from its absolute value. Given a parameter $θ\in \mathbb{R}$, we derive the following characterization of uniqueness in terms of rigidity of a set $Λ\subseteq \mathbb{R}$: if $\mathcal{F}$ is a vector space of entire functions containing all exponentials $e^{ξz}, \, ξ\in \mathbb{C} \setminus \{ 0 \}$, then every $F \in \mathcal{F}$ is uniquely determined up to a unimodular phase factor by $\{|F(z)| : z \in e^{iθ}(\mathbb{R} + iΛ)\}$ if and only if $Λ$ is not contained in an arithmetic progression $a\mathbb{Z}+b$. Leveraging this insight, we establish a series of consequences for Gabor phase retrieval and Pauli-type uniqueness problems. For instance, $\mathbb{Z} \times \tilde{\mathbb{Z}}$ is a uniqueness set for the Gabor phase retrieval problem in $L^2(\mathbb{R}_+)$, provided that $\tilde{\mathbb{Z}}$ is a suitable perturbation of the integers.

description: Surface plasmon biosensors have raised much interest over the past few decades for their potential in biosensing applications. This thesis investigates the plasmon-polariton Bragg grating, which is a novel structure that supports surface plasmon modes. Plasmon-polariton Bragg gratings PPBGs consist of metal stripes embedded in Cytop. A number of designs were investigated to evaluate the biosensing capabilities of the device. The biosensing performance was studied for both bulk and surface sensitivities via wavelength interrogation. The biosensing study was conducted by observing changes in the effective refractive indices of the supported modes by changing the index of the sensing solution for bulk sensitivity, and by changing the thickness of the adlayer that represents the binding of the target analyte to the sensing surface for surface sensitivity. A theoretical assessment of the achievable sensitivity and detection limit for PPBGs is conducted via two approaches, wavelength and output power interrogation.

description: This study presents a thorough analysis of an eco-epidemiological model that integrates infectious diseases in prey, prey aggregation, and the dual fear effect induced by predators. We establish criteria for determining the existence of equilibrium points, which carry substantial biological significance. We establish the conditions for the occurrence of Hopf, saddle-node, and transcritical bifurcations by employing fear parameters as key bifurcation parameters. Furthermore, through numerical simulations, we demonstrate the occurrence of multiple zero-Hopf (ZH) and saddle-node transcritical (SNTC) bifurcations around the endemic steady states by varying specific key parameters across the two-parametric plane. We demonstrate that the introduction of predator-induced fear, which hinders the growth rate of susceptible prey, can lead to the finite time extinction of an initially stable susceptible prey population. Finally, we discuss management strategies aimed at regulating disease transmission, focusing on fear-based interventions and selective predation via predator attack rate on infectious prey.

description: Nul doute qu’Andréa de Nerciat promeut un joyeux libertinage. Cette qualité, constamment mise de l’avant, atteste de l’exemplarité de son œuvre dans la tradition du libertinage solaire. Aussi notre thèse veut-elle montrer comment l’écriture de Nerciat propose la vision d’une sexualité solaire. L’étude systématique et détaillée des neuf œuvres suivantes tentera de cerner la rhétorique hédoniste de ce joyeux libertinage : Félicia ou mes fredaines (1775), Contes nouveaux (1777), La matinée libertine (1787), Le doctorat impromptu (1788), Monrose ou le libertin par fatalité (1792), Mon Noviciat ou les joies de Lolotte (1792), Les Aphrodites, fragments thali-priapiques pour servir à l’histoire du plaisir (1793) et Les contes polissons (saugrenus) (1799). La rhétorique pragmatique, instrument d’analyse contemporain, constitue le cœur de notre approche théorique puisqu’elle sert à montrer comment l’érographie de Nerciat fait naître, encore à notre époque, le désir et la jouissance grâce à des procédés de renouvellement du plaisir intégrés dans sa rhétorique hédoniste. Elle permet donc de mettre en lumière la façon dont Nerciat manie, avec efficacité et souvent avec originalité, les procédés littéraires et langagiers. De même, elle met en valeur les enjeux du récit érographique, qui tend à être performant, autant du point de vue de la narration, de l’intrigue et de la mise en scène. La rhétorique solaire de Nerciat est également promue par les personnages de son œuvre qui sont, en grande majorité, des êtres désirants et consentants. De différentes classes sociales, ils participent de manière conviviale aux aventures érotiques. De plus, Nerciat réserve un rôle original aux personnages féminins qui, en plus d’être majoritaires dans son œuvre, incarnent des héroïnes volontaires et maîtresses de leurs plaisirs sexuels. La rhétorique pragmatique participe également à l’érotisation de l’atmosphère qui entoure les personnages dans le but d’intensifier le désir et ainsi de créer des ambiances et des espaces variés favorables à l’épanouissement d’une sexualité que Nerciat veut solaire.

description: This paper explores the potential impacts of large language models (LLMs) on the Chinese labor market. We analyze occupational exposure to LLM capabilities by incorporating human expertise and LLM classifications, following the methodology of Eloundou et al. (2023). The results indicate a positive correlation between occupational exposure and both wage levels and experience premiums at the occupation level. This suggests that higher-paying and experience-intensive jobs may face greater exposure risks from LLM-powered software. We then aggregate occupational exposure at the industry level to obtain industrial exposure scores. Both occupational and industrial exposure scores align with expert assessments. Our empirical analysis also demonstrates a distinct impact of LLMs, which deviates from the routinization hypothesis. We present a stylized theoretical framework to better understand this deviation from previous digital technologies. By incorporating entropy-based information theory into the task-based framework, we propose an AI learning theory that reveals a different pattern of LLM impacts compared to the routinization hypothesis.
