Democracy promotion in a post-political world
Creators: name: Schmidt, Jessica
Publisher: name: University of Westminster
Year: 2013

description: This thesis is concerned with democracy promotion’s unexpected and often unheralded new role and trajectory. While having retreated from the limelight cast on democracy promotion in the early 1990s, the thesis argues that democracy promotion demonstrated considerable staying power in coming to work silently but vigorously across, and even through, other international policy areas. The thesis traces and conceptualises the trajectory of democracy promotion from an independent policy to its generalisation and resurfacing in conflict management, statebuilding and climate change policy discourses. In its methodological approach this study draws on critical realism and adopts a genealogical ethos for ordering and interpreting the textual and programmatic material. The trajectory and displacement of democracy promotion are analysed and conceptualised by inferring from the work of Michel Foucault and Hannah Arendt. In supplementing Foucault’s work on forms of governing, power and subjectivity with aspects of Arendt’s work on the human condition and politics, the thesis takes a different analytical approach than the common liberal framing. Rather than investigating democracy promotion as part of (neo)liberal governmentality it explores the discourse through the prism of the social. In doing so, the radically reworked meaning of democracy and its role for international policymaking can be captured. The rise of the social and its impact on the understanding of democracy and the modality of its promotion has been largely missed in existing literature and remains under-theorised. This thesis argues that while once democracy promotion was concerned with elections and institutions in the formal political sphere of constituted power, democracy now has a new lease of life in a different sphere of problem-solving and governing: the sphere of the governance of the self. The sphere of self-governance unfolds not in terms of the autonomous human subject but rather emerges as a sphere permeated by relationships into which the human subject is embedded and through which it is enabled to govern itself.

description: In recent years, the pharmaceutical industry has embarked on an extensive program to modernize its manufacturing resources. Recognizing the limitations of traditional mass manufacturing, the industry is now focused on developing new production systems that can deliver high-quality medicines with enhanced efficiency, flexibility, agility, and reliability. To realize this vision, innovations in three key areas are being pursued: continuous processing, personalized medicine, and Industry 4.0. This thesis contributes towards the industry’s goal by focusing on the development of an advanced system to manufacture solid oral drug products. This system is centered around a pharmaceutical additive manufacturing technology called drop on demand (DoD) printing. This technology is highly effective in making personalized drug products, which allow for customizing dose attributes such as drug loading, release behavior, formulation type, and dosage form, based on patient requirements. To develop the DoD printer into an advanced production system, technologies such as end-to-end continuous processing, real time quality assurance, and automated operation need to be incorporated into it. The studies presented in this thesis implement different aspects of these technologies in the printer. To enable end to end operation, a novel solvent switch process called three phase settling is developed to integrate the DoD system with upstream steps for synthesizing the active ingredient. To facilitate automated processing of formulations with different active ingredients, excipients, and particle concentrations, a model framework is developed to recommend operating conditions for the DoD platform that can deliver on-spec printer operation. To expand the range of personalized dosage forms offered by the system, the manufacturing of a new category of drug products, called mini-tablets, is demonstrated. To provide reconfigurability and quality assurance capabilities in the platform, modular design and process monitoring tools are implemented. To aid optimization and control of drug production processes, a digital twin is developed by combining the models developed for DoD, solvent switch, synthesis, and crystallization operations. The research presented in this thesis lays the foundation for developing the next generation of manufacturing systems for drug products. Incorporation of scalability, autonomous operation, and real time release prediction are critical steps in facilitating the next phase of its development – deployment in real-world manufacturing scenarios.

description: When conducting a Bell test, it is normal to assume that the preparation of the quantum state is independent of the measurements performed on it. Remarkably, the violation of local realism by entangled quantum systems can be certified even if this assumption is partially relaxed. Here, we allow such measurement dependence to correlate multiple runs of the experiment, going beyond previous studies that considered independent and identically distributed (i.i.d.) runs. To do so, we study the polytope that defines block-i.i.d. measurement-dependent local models. We prove that non-i.i.d. models are strictly more powerful than i.i.d. ones, and comment on the relevance of this work for the study of randomness amplification in simple Bell scenarios with suitably optimised inequalities.
title: Extracting likely scenarios from ensemble forecasts in real-time
Creators: name: Boykin, Kristine Adelaide
Publisher: name: University of Reading
Year: 2023

description: With the development of ensemble forecasting, operational meteorologists are faced with large amounts of constantly updating complex information which they must quickly interpret to issue forecasts and warnings. In this thesis a novel clustering technique is introduced that reduces ensemble forecasts to a few representative forecast trajectories. Clustering is performed using k-medoids with the distance metric defined by the Fractions Skill Score (FSS) of the gradient in 850hPa wet-bulb potential temperature to group ensemble members with similar frontal features. The number of clusters is selected using lead-time-coherence of the clusters over a window of interest when clustering is most distinct. Members nearest to the centre of each cluster during this window of interest are chosen as representative members to be viewed by forecasters. Clustering is found to be more coherent during low predictability events when ensemble spread is large. The clustering method was compared to an alternative that uses the FSS of large-scale rain rate and it was found that while similar, results are not interchangeable. The gradient of wet-bulb potential temperature had higher time-coherence and therefore was judged preferable. The method was evaluated during the Met Office winter testbed of 2021-22, and representative members found were found to correspond well to forecasters judgement of the distinct scenarios in the ensemble, hence providing a useful reduction in the data that needs to be considered in issuing forecasts. The method draws attention to low predictability events that appear across several forecasts. While this method has been created to fill a need with ensemble forecasting, it is anticipated that it can be used in many other areas of research such as identifying circulation patterns, seasonal and climate forecast trajectories, and exploring different meteorological phenomena by modifying variable choice and other parameters. The method is also planned for use at the Met Office.
Towards formalisation of situation-specific computationsin pervasive computing environments
Creators: name: Shojanoori, Reza
Publisher: name: University of Westminster
Year: 2013

description: We have categorised the characteristics and the content of pervasive computing environments (PCEs), and demonstrated why a non-dynamic approach to knowledge conceptualisation in PCEs does not fulfil the expectations we may have from them. Consequently, we have proposed a formalised computational model, the FCM, for knowledge representation and reasoning in PCEs which, secures the delivery of situation and domain specific services to their users. The proposed model is a user centric model, materialised as a software engineering solution, which uses the computations generated from the FCM, stores them within software architectural components, which in turn can be deployed using modern software technologies. The model has also been inspired by the Semantic Web (SW) vision and provision of SW technologies. Therefore, the FCM creates a semantically rich situation-specific PCE based on SWRL-enabled OWL ontologies that allows reasoning about the situation in a PCE and delivers situation specific service. The proposed FCM model has been illustrated through the example of remote patient monitoring in the healthcare domain. Numerous software applications generated from the FCM have been deployed using Integrated Development Environments and OWL-API.
A combinatorial Hopf algebra for the boson normal ordering problem

description: In the aim to understand the generalization of Stirling numbers occurring in the bosonic normal ordering problem, several combinatorial models have been proposed. In particular, Blasiak \emph{et al.} defined combinatorial objects allowing to interpret the number of $S_{\bf{r,s}}(k)$ appearing in the identity $(a^†)^{r_n}a^{s_n}\cdots(a^†)^{r_1}a^{s_1}=(a^†)^α\displaystyle\sum S_{\bf{r,s}}(k)(a^†)^k a^k$, where $α$ is assumed to be non-negative. These objects are used to define a combinatorial Hopf algebra which specializes to the enveloping algebra of the Heisenberg Lie algebra. Here, we propose a new variant of this construction which admits a realization with variables. This means that we construct our algebra from a free algebra $\mathbb{C}\langle A \rangle$ using quotient and shifted product. The combinatorial objects (B-diagrams) are slightly different from those proposed by Blasiak \emph{et al.}, but give also a combinatorial interpretation of the generalized Stirling numbers together with a combinatorial Hopf algebra related to Heisenberg Lie algebra. The main difference comes from the fact that the B-diagrams have the same number of inputs and outputs. After studying the combinatorics and the enumeration of B-diagrams, we propose two constructions of algebras called Fusion algebra $\mathcal{F}$, defined using formal variable and another algebra $\mathcal{B}$ constructed directly from the B-diagrams. We show the connection between these two algebras and that $\mathcal{B}$ can be endowed with a Hopf structure. We recognize two already known combinatorial Hopf subalgebras of $\mathcal{B}$ : $\mathrm{WSym}$ the algebra of word symmetric functions indexed by set partitions and $\mathrm{BWSym}$ the algebra of biword symmetric functions indexed by set partitions into lists.

description: We used the Revised Flat Galaxy Catalog (RFGC) to create a sample of ultra-flat galaxies (UFG) covering the whole northern and southern sky apart from the Milky Way zone. It contains 817 spiral galaxies seen edge-on, selected into the UFG sample according to their apparent axial ratios $(a/b)_B\geq10.0$ and $(a/b)_R\geq8.53$ in the blue and red bands, respectively. Within this basic sample we fixed an exemplary sample of 441 UFG galaxies having the radial velocities of $V_{LG} < 10000$ km s$^{-1}$, Galactic latitude of $\mid b\mid>10^{\circ}$ and the blue angular diameter of $a_B > 1.0^{\prime}$. According to the Schmidt test the exemplary sample of 441 galaxies is characterized by about (80-90)% completeness, what is quite enough to study different properties of the ultra-flat galaxies. We found that more than 3/4 of UFGs have the morphological types within the narrow range of $T= 7\pm1$, i.e. the thinnest stellar disks occur among the Scd, Sd, and Sdm types. The average surface brightness of UFG galaxies tends to diminish towards the flattest bulge-less galaxies. Regularly shaped disks without signs of asymmetry make up about 2/3 both among all the RFGC galaxies, and the UFG sample objects. About 60% of ultra-flat galaxies can be referred to dynamically isolated objects, while 30% of them probably belong to the scattered associations (filaments, walls), and only about 10% of them are dynamically dominating galaxies with respect to their neighbours.

description: We investigate the asymptotic structure of the three dimensional warped anti de sitter black holes in the Bergshoeff, Hohm and Townsend massive gravity using the canonical Hamiltonian formalism. We define the canonical asymptotic guage generators, which produce the conserved charges and the asymptotic symmetry group for the warped anti de sitter black holes. The attained symmetry group is described by a semi direct sum of a Virasoro and a KacMoody algebra. Using the Sugawara construction, we obtain a direct sum of two Virasoro algebras. We show that not only the asymptotic conserved charges satisfy the first law of black hole thermodynamics, but also they lead to the expected Smarr formula for the warped anti de sitter black holes. We also show that the black hole entropy obeys the Cardy formula of the dual conformal field theory .

description: We use a high resolution cosmological zoom simulation of a Milky Way-sized halo to study the observable features in velocity and metallicity space associated with the dynamical influence of spiral arms. For the first time, we demonstrate that spiral arms, that form in a disc in a fully cosmological environment with realistic galaxy formation physics, drive large-scale systematic streaming motions. In particular, on the trailing edge of the spiral arms the peculiar galacto-centric radial and azimuthal velocity field is directed radially outward and azimuthally backward, whereas it is radially inward and azimuthally forward on the leading edge. Owing to the negative radial metallicity gradient, this systematic motion drives, at a given radius, an azimuthal variation in the residual metallicity that is characterised by a metal rich trailing edge and a metal poor leading edge. We show that these signatures are theoretically observable in external galaxies with Integral Field Unit instruments such as VLT/MUSE, and if detected, would provide evidence for large-scale systematic radial migration driven by spiral arms.

Creators: name: Marozzi, Armando
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2022

description: This thesis studies the communication of the European Central Bank (ECB) from different angles. In particular, the first essay analyses the effects of the ECB’s fiscal communication on the macroeconomy of the euro area. The findings are threefold: first, a fiscally hawkish communication significantly lowers output and inflation; second, industrial production and price levels would have been higher during the Great Recession and the sovereign-debt crisis had the ECB held constant its fiscal communication; third, government bond purchases are inversely related to the ECB’s “fiscal stance”, that is, the ECB becomes more fiscally hawkish after a monetary policy easing. The second essay proposes to nowcast the ECB’s press conferences exploiting the flow of conventional and textual data that become available between two consecutive press conferences. In out-of-sample nowcasting experiments, the model provides an accurate tracking of the ECB monetary policy stance and decisions. The inclusion of textual variables contributes significantly to the gradual improvement of the model performance. The third essay investigates the effectiveness of monetary policy conditional on the level of agreement in the ECB Governing Council. The results illustrate significant asymmetry: while expansionary monetary policy propagates as documented in the literature in the scenario of high agreement, the effects of monetary policy accommodation vanish when disagreement is high.

The average pair-wise correlation of these alphas is low, 15.9%. The returns are strongly correlated with volatility, but have no significant dependence on turnover, directly confirming an earlier result based on a more indirect empirical analysis. We further find empirically that turnover has poor explanatory power for alpha correlations.

Considering a coupled nonlinear system with fractional Laplacian, we first establish a decay at infinity principle and a narrow region principle. Using these principles, we obtain two radial symmetry results for the decaying solutions of the fractional Laplacian systems. Our method can be applied to fractional Schrödinger systems and fractional Hénon systems.

description: We assess the impact of cell cycle noise on gene circuit dynamics. For bistable genetic switches and excitable circuits, we find that transitions between metastable states most likely occur just after cell division and that this concentration effect intensifies in the presence of transcriptional delay. We explain this concentration effect with a 3-states stochastic model. For genetic oscillators, we quantify the temporal correlations between daughter cells induced by cell division. Temporal correlations must be captured properly in order to accurately quantify noise sources within gene networks.

description: This study demonstrates the significant effect of the recoil pressure and Marangoni convection in laser powder bed fusion (L-PBF) of 316L stainless steel. A three-dimensional high fidelity powder-scale model reveals how the strong dynamical melt flow generates pore defects, material spattering (sparking), and denudation zones. The melt track is divided into three sections: a topological depression, a transition and a tail region, each being the location of specific physical effects. The inclusion of laser ray-tracing energy deposition in the powder-scale model improves over traditional volumetric energy deposition. It enables partial particle melting, which impacts pore defects in the denudation zone. Different pore formation mechanisms are observed at the edge of a scan track, at the melt pool bottom (during collapse of the pool depression), and at the end of the melt track (during laser power ramp down). Remedies to these undesirable pores are discussed. The results are validated against the experiments and the sensitivity to laser absorptivity is discussed.
Ostrogradsky in Theories with Multiple Fields

description: We review how the (absence of) Ostrogradsky instability manifests itself in theories with multiple fields. It has recently been appreciated that when multiple fields are present, the existence of higher derivatives may not automatically imply the existence of ghosts. We discuss the connection with gravitational theories like massive gravity and beyond Horndeski which manifest higher derivatives in some formulations and yet are free of Ostrogradsky ghost. We also examine an interesting new class of Extended Scalar-Tensor Theories of gravity which has been recently proposed. We show that for a subclass of these theories, the tensor modes are either not dynamical or are infinitely strongly coupled. Among the remaining theories for which the tensor modes are well-defined one counts one new model that is not field-redefinable to Horndeski via a conformal and disformal transformation but that does require the vacuum to break Lorentz invariance. We discuss the implications for the effective field theory of dark energy and the stability of the theory.

description: Recent observation of some luminous transient sources with low color temperatures suggests that the emission is dominated by optically thick winds driven by super-Eddington accretion. We present a general analytical theory of the dynamics of radiation pressure-driven, optically thick winds. Unlike the classical adiabatic stellar wind solution whose dynamics are solely determined by the sonic radius, here the loss of the radiation pressure due to photon diffusion also plays an important role. We identify two high mass loss rate regimes ($\dot{M} > L_{\rm Edd\,}/c^2$). In the large total luminosity regime the solution resembles an adiabatic wind solution. Both the radiative luminosity, $L$, and the kinetic luminosity, $L_k$, are super-Eddington with $L < L_k$ and $L \propto L_k^{1/3}$. In the lower total luminosity regime most of the energy is carried out by the radiation with $L_k < L \approx L_{\rm Edd\,}$. In a third, low mass loss regime ($\dot{M} < L_{\rm Edd\,}/c^2$), the wind becomes optically thin early on and, unless gas pressure is important at this stage, the solution is very different from the adiabatic one. The results are independent from the energy generation mechanism at the foot of the wind, therefore they are applicable to a wide range of mass ejection systems, from black hole accretion, to planetary nebulae, and to classical novae.

title: CEO-board dynamics in UK-based social enterprises and its influence on value delivery
Creators: name: Linden, Nitzan
Publisher: name: University of Reading
Year: 2022

description: This exploratory, qualitative study utilises twenty-eight interviews with Chief Executive Officers (CEOs), board members and chairs of UK-based social enterprises (SEs) to explore governance dynamics and its influence on value delivery and organisational performance. The thematic analysis undertaken in this study uses the stewardship theory to identify the CEO–board dynamics, the unique nature and roles of CEOs and boards in an SE context, as well as complexities and tensions that impact the value that is delivered. The findings of this thesis advance the knowledge of how CEO– board dynamics in SEs influence value delivery, making important contributions to both stewardship theory and SEs’ governance literature. The findings emphasise the importance of the role of the CEO and board in SEs, the type of relationship they establish from the very beginning, their collaboration, and how critical their partnership is, as it has a major impact on value delivery and performance. Moreover, this thesis finds no empirical support for the idea of major governance tensions in SEs, which can be seen in other types of organisations. Instead, evidence suggests that the little tensions that were reported in this thesis are mostly healthy and lead to growth or are being solved quickly by the relevant people. Finally, this thesis contributes to practice by providing an emerging model that is based on stewardship theory and emphasises the importance of positive CEO–board dynamics in order to increase organisational performance and deliver value in SEs.

description: Variability studies hold information on otherwise unresolvable regions in Active Galactic Nuclei (AGN). Population studies of large samples likewise have been very productive for our understanding of AGN. These two themes are coming together in the idea of systematic variability studies of large samples - with SDSS, PanSTARRS, and soon, LSST. I summarise what we have learned about the optical and UV variability of AGN, and what it tells us about accretion discs and the BLR. The most exciting recent results have focused on rare large-scale outbursts and collapses - Tidal Disruption Events, changing-look AGN, and large amplitude microlensing. All of these promise to give us new insight into AGN physics.

Schreiben im Sprachmarkt
Creators: name: Miglar, Katrin
Publisher: name: Medienimpulse
Year: 2022

description: In diesem Essay wird das Schreiben von wissenschaftlichen Abschlussarbeiten nach Pierre Bourdieu im Kontext eines Sprachmarktes gedeutet. Ziel dieser Textproduktion ist es, einen Bildungsabschluss zu erwerben und langfristig (kulturelles) Kapitel zu generieren. Doch, was bedeutet das für Mitarbeitende und/oder Peer-Tutor:innen an Lese- und Schreibeinrichtungen, die Studierende in Form von Schreibberatungen begleiten? Sind Schreibberatungen eine Bildungsinvestition? Anhand von Bourdieus Theorien erfolgt eine Reflexion des Berufs-, Aufgaben- und Tätigkeitsprofils von Schreibberatenden. Der Essay schließt mit der Conclusio, dass Schreibberatungen den Hochschulen, die nach Marktlogiken funktionieren, eine soziale und humanistische Komponente zurückgeben, dabei aber den Mechanismen des Sprachmarktes genauso verhaftet bleiben.

description: Consider the class RBLie of Lie algebras equipped with a Rota---Baxter operator. Then the forgetful functor RBLie --> Lie has a left adjoint one denoted by $U_{RB}(\cdot)$. We prove an "operator" analogue of the Poincare---Birkhoff---Witt theorem for $U_{RB}(L)$, where $L$ is an arbitrary Lie algebra, by means of Gröbner---Shirshov bases theory for Lie algebras with an additional operator.

Au-delà des chiffres : la christianisation à contretemps du Soudan du Sud
Creators: name: Pérouse de Montclos, Marc-Antoine
Publisher: name: Ceped
Year: 2024

description: Peu étudié en France, le Soudan du Sud a accédé à l’indépendance en 2011 et s’apprête à tenir des élections d’ici la fin 2024. Bien qu’il continue de connaître de fortes tensions, il retient d’autant moins l’attention que les feux de l’actualité sont plutôt braqués sur la guerre au Soudan, au nord. La trajectoire politique du Soudan du Sud mérite pourtant d’être analysée au prisme d’une christianisation très rapide qui peut tout à la fois se lire comme une réponse aux défis de la modernité, une affirmation identitaire et un acte de résistance contre la junte islamiste autrefois au pouvoir à Khartoum. Cette étude revient ainsi sur les succès d’une évangélisation à contretemps dont les représentations font appel à des registres de compréhension assez différents au niveau local, national et global.
