The thesis is concerned with parochial patronage, recruitment of beneficed and unbeneficed secular clergy, and the quality of pastoral provision during the thirteenth century, with reference to the dioceses of Worcester and Hereford.
Chapter one examines the main characteristics of the dioceses and the ways in which these affected religious life, concentrating on the parish structure and the impact of war.
Chapter two concerns parochial patronage as a property right, tracing the distribution of advowson ownership and examining how patronage was viewed by patrons themselves. Amongst laymen there survived anachronistic attitudes reminiscent of proprietary right; while for monasteries the financial advantages of appropriation were generally as important as the actual right of presentation.
Chapter three examines the exercise of parochial patronage by the different advowson-owning groups. Although the composition of the beneficed clergy reflected the pressure to provide for relatives and retainers, the quality of pastoral provision was not affected by the type of patronage; while much influence was exercised by and between all patronage groups. Poorer churches and vicarages were often held by obscure clerks, possibly promoted through merit.
Chapter four concerns the origins, recruitment and employment of unbeneficed clergy. Most apparently found employment within the parish structure or in private service, the process being partially discernible in the granting of titles by potential (and usually local) employers. Some possessed their own lands, though most probably did not.
Chapter five examines the secular clergy in local society and their relations with the laity. Their incomes generally set them apart from the lesser peasantry, although as those of unbeneficed clerks were largely unregulated the vicarage system remained undermined. In other respects attempts to reform the clergy were generally successful, although the laity continued to exert much influence on religious life and even on recruitment of assistant clergy.

To thrive in an ever-changing world, animals must rapidly and flexibly adapt their behaviour according to their needs. Some problems require an initial period of learning through trial and error; others can be quickly solved by generalising and integrating information from previous experiences. In this thesis, I explore anatomical and functional features of the brain system that support these learning and decision-making processes. In particular, I focus on the role of the orbitofrontal cortex (OFC) and midbrain dopaminergic projections which play a critical role in sustaining flexible behaviour. Behavioural research suggests the OFC is functionally heterogeneous along its medial–lateral and anterior–posterior axes. In Chapter 3, I investigated whether this functional heterogeneity is underpinned by differences in anatomical connectivity by simultaneously characterising the input patterns into the anterior lateral, posterior lateral, and posterior ventral portions of the rat OFC. The results show that these OFC subdivisions receive distinct and topographically organised inputs from various thalamic nuclei, basolateral amygdala, and various cortical areas. Learning and behavioural adaptation are particularly important when expectations are not met, eliciting reward prediction errors (RPEs) –the difference between expected and actual outcomes. In the brain, the encoding of these teaching signals has long been linked with the activity of dopamine neurons. However, there has been no direct demonstration between the behaviourally derived haemodynamic signatures of RPEs measured with functional magnetic resonance imaging (fMRI) and dopamine release. Thus, to establish the contribution of dopamine to haemodynamic signatures of RPEs encoding, Chapter 4 combined recordings of haemodynamic signals in the OFC and nucleus accumbens (NAc) with lesioning of NAc dopaminergic inputs. OFC responses were surprisingly larger after lesioning of dopaminergic inputs to NAc, suggesting a potential balance between the activity of the two regions. Dopaminergic signalling dysregulation is thought to drive the neuronal mechanisms underlying psychotic symptoms such as delusions through disruption of RPEs encoding in frontostriatal circuits. Chapter 5 shows that maladaptive behaviour during amphetamine-induced hyperdopaminergic states is linked to disruption of NAc haemodynamic responses. Then, in Chapter 6, I describe the development of a novel rodent behavioural paradigm in which rats must develop a model of the world to maximise reward, for investigating how the brain encodes information during generalisation. Chapter 7 summarises the findings from the previous chapters and discusses their implications for our understanding of how the brain encodes information for supporting flexible behaviour.
Classical and quantum structures in computation
Keywords: sheaf theory
contextuality
quantum computing
categorical quantum mechanics
category theory

Quantum mechanics exhibits many counter-intuitive features, which challenge our classical understanding of the world. This makes the theory simultaneously difficult to grasp, and a source of great potential for new technologies.
We study various characteristics of classical and quantum mechanics and their respective roles in computation. This is interesting from a philosophical perspective, as it brings us a small step closer to understanding the nature of quantum mechanics. Furthermore, it leads us to discover scenarios where quantum resources provide a genuine advantage over classical resources, as well as more intuitive ways to model quantum protocols.
Firstly, we explore the concept of quantum contextuality, which distinguishes uniquely-quantum experimental outcomes from outcomes that can be realised classically. In pursuit of a universal theory of contextuality, we unify two abstract frameworks: the sheaf-theoretic approach to contextuality by Abramsky and Brandenburger and the equivalence-based approach by Spekkens.
We apply the sheaf-theoretic formalism to the field of communication complexity. We derive a bound on the success probability of a communication complexity protocol, based on the amount of contextuality present in its quantum resource. We provide a set of necessary conditions for distributed functions that allow a contextual advantage.
Secondly, we consider a family of bicategorical models to describe the interaction of classical and quantum information in quantum protocols. We prove that this family is symmetric monoidal, and therefore suitable for describing compound and parallel protocols. This family serves as a mathematical foundation for the planar language for quantum protocols by Vi- cary. Important examples of this family are the bicategories 2Hilb and 2Vect. Additionally, we introduce the structure 2[CP∗[FHilb]], which contains a symmetric monoidal bicategory of mixed states and completely positive maps. This allows a unified description of quantum teleportation and classical encryption in a single 2-category, as well as a universal security proof applicable simultaneously to both scenarios.
As part of the process, we develop extensive categorical machinery for constructing symmetric monoidal structures of bicategories, pseudo functors, pseudo transformations and modifications. We consider a method of constructing symmetric monoidal bicategories from symmetric monoidal double categories. We show that this method can be generalised to a functor from the locally cubical bicategory of monoidal double categories to the locally cubical bicategory of monoidal bicategories.

La vida es sueño

Research on the comedia in performance has partially ignored the actor’s role in establishing aesthetic and ideological meanings in early modern and (post)modern stagings. This study addresses this gap by employing four performances of La vida es sueño as case studies: the 1632-1636 première (Chapter I) and three CNTC productions from 1996 (Chapter II), 2000 (Chapter III), and 2012 (Chapter IV). Its objective is to answer the following questions: what is the players’ role in conveying dramatic features (characterisation and conflict)? What resources –such as paralinguistic features, gestures, and use of space– do they employ to achieve this? How do they articulate aspects from their socio-political context onto the stage? As these issues are examined, this thesis discusses (a) the adaptations’ level of (un)faithfulness to the play-text/première and (b) their (lack of) relevance vis-à-vis their aesthetic and ideological environment.
To do so, it introduces two dichotomies: the fundamentalist/reformist approach –which evaluates (a)– and the dry/wet perspective –which considers (b). Methodologically, the acting is analysed through “thick” description (specific scenes reveal generalities about the productions) and a particularised framework for each mise-en-scène. The comparison shows that there are two perspectives in the (post)modern staging of La vida es sueño/the comedia: (1) The conservative one –catalogued as dry and fundamentalist– is illustrated by the 1996 and 2012 productions. This perspective fails to engage with the play’s most contemporary themes (e.g., violence), while respecting the script/première (e.g., introducing few extra-textual scenes). (2) The radical one –catalogued as wet and reformist– is exemplified by the 2000 version. This approach engages with political criticism (e.g., the spectator’s problematic attitudes towards cruelty/suffering) and transgresses Calderón’s play-text (e.g., by introducing references to fascism). The main contribution of this study is that it questions and reinstates the relevance of the performance of Calderón’s play and the comedia today.
What is known about climate change? A knowledge graph approach

The latest findings from the Intergovernmental Panel on Climate Change Sixth Assessment Report retells a story already told in 1979 in greater detail --- that climate change is happening because of human causes. However, the progress on addressing the climate crisis hardly corresponds to the media's nearly 40 years of news coverage. A widely cited barrier to progress is the lack of knowledge to comprehend the various interacting aspects of climate change. As a dynamic complex system, climate change is a deeply relational systems-level problem that requires communication and mental models capable of communicating system complexities. To establish the extent of relations and knowledge formations by past communications, this paper offers a methodological innovation enabling network analysis of unstructured texts. This research developed a reproducible automated semantic network approach using natural language processing and open information extraction tools to construct knowledge graphs (KGs) on climate change news coverage in 5 countries using news articles (N=19,684) from 1990 to 2020. Country comparisons were carried out cross-sectionally and longitudinally. The findings show that the KGs are structurally similar while static but differed substantially in longitudinal patterns. Countries performing better in climate commitments saw a uniform increase in the salience and embedded of concepts, while in those less progressive countries, concepts become salient sporadically. The study concludes by recommending a concerted communication model that gives equal and parallel issue-attention to the causal, action, and physical characteristic and consequence frames of climate change to facilitate understanding of the system complexity of climate change.
Cardiovascular disease under the lens of automated 3D analysis of the heart
Keywords: cardiac function

3D shape computational models

Improving healthcare systems mandates a shift towards personalised and preventive medicine, especially in the management of cardiovascular diseases, the world leading cause of death. The anatomy and function of the heart can be accurately and non-invasively assessed using cardiac magnetic resonance. Nevertheless, it is not yet fully understood how their interplay modulates disease outcomes. In this regard, this Thesis (1) reviews the crucial role of computational modelling towards precision cardiology, by building the ‘digital twin’ of a patient; (2) develops a fully automated pipeline to construct 3D computational models of human left ventricle from 2D cardiac magnetic images, using state-of-art deep learning approaches; and (3) proposes an enhanced structural and functional analysis to disentangle how adverse outcomes are modulated in cardiovascular disease. This is showcased in acute myocardial infarction, the deadliest cardiovascular disease not only on first manifestation, but on reoccurrence and secondary adverse outputs. In this scenario, the approach introduced in this Thesis is shown to provide additional prognostic information towards a better post-infarction management. Moreover, it identifies 3D shape and contraction patterns that are related to adverse outcomes, building a more profound understanding of remodelling after infarction. Furthermore, the automation of the analysis removes the burden of manual annotations and intra- and inter-observer variability, as confounders of prognosis. All this argues for the clinical impact of this Thesis. Ultimately, the Thesis evidences the potential of 3D computational models for cardiovascular disease management, towards personalised and preventive care.
"And now on BBC Radio 4…": imaginative geographies of forced migration and refugee settlement in Europe on the airwaves

imaginative geographies

Geographers have examined the history, materiality, and geopolitical power of radio, but there has been little interest in contemporary radio journalism and its capacity to shape geographical imaginations. This thesis addresses this research gap by exploring how imaginative geographies of forced migration and refugee settlement in Europe were constructed on BBC Radio 4 between January 2014 and March 2019, and by examining how broadcasts were produced by journalists and are heard and imagined by listeners. The protracted Syrian conflict, recent drownings in the Mediterranean, and rise of populism in Europe raise important questions about media representations as an act of power with the potential to regulate imagined communities of belonging and condition a sense of responsibility and care for others. By focusing on BBC Radio 4 and the audible spectacle of Europe’s migration ‘crisis’, the thesis seeks to further understandings of the journalistic storytelling of migration that to date have focused almost exclusively on print and photographic journalism, and develop theorisations of the ear and mind’s eye in radio geography by revealing the affective and experiential power of broadcasts. The thesis is organised around three empirical chapters: Chapter 4 draws on a thematic analysis of 172 broadcasts across a range of programme genres and identifies two contrasting imaginative geographies of migration that reveal Radio 4 to be a disparate and, at times, contradictory site of representation; Chapter 5 analyses 17 semi-structured interviews conducted with BBC journalists, editors, producers, and senior leaders to reveal the organisational structures and journalistic practices that shape the production of broadcasts; and Chapter 6 draws on 51 listener diaries written in response to a digital playlist of 12 selected broadcasts to reveal how stories and imaginaries of migration, articulated through sounds and voices, are heard, imagined, and felt. The thesis responds to calls in cultural and political geography for analyses of radio that attend to the discursive and affective impacts of listening, and for research on representations of migration in alternative media to print journalism.
The Perugian nobility c. 1200-1430
Keywords: Italy
Perugian
nobility
Perugia

Besides seeking to outline social changes over two centuries in a medium-sized Italian town very different from the greater centres of Northern and Central Italy, this study aims chiefly at defining the concept of nobility as it appeared at Perugia, tracing changes in its meaning and investigating its relationship to knighthood, so important a feature in the definition of nobility in areas of Northern Europe, and to the Italian anti-magnate legislation.
Attention has thus been directed towards the changing patterns in social vocabulary of honour and distinction as well as to a prosopographical analysis of those families who, by 1333, were classified as noble in the Perugian magnate lists. Their overwhelmingly rural base has been noted. The ancient territorial aristocracy continued both independent and strong, although newer families had emerged c.1200 upon old lay and ecclesiastical lands.
Perugian political history has been re-evaluated; special consideration has been given to the actual powers of the popolo during the period of its apparent predominance, c.1260-1400, to the complex interaction between town and countryside, to the persistence of private jurisdictions and to the degree to which the rural nobility was attracted to urban life. Finally, from 1370, the gradual assimilation of members of the mercantile classes to the ranks of the nobility has been traced, together with the formation of an urban oligarchy. In this way, both noble and civic consciousness in Perugia at the close of the Middle Ages were considerably modified.
Essays in comparative political economy: bureaucracy and participation in policymaking
Keywords: Regulatory politics
comparative political economy
participatory development

This DPhil project addresses three distinct, yet interrelated, questions with respect to the nature of contemporary digital capitalism and participatory governance. Closely following standard comparative political economy research practices, I test several established theories about bureaucratic influence and participatory benefits on contemporary policymaking cases across capitalist democracies (Paper 1 and Paper 2). I also develop a somewhat more original theoretical proposition on the strategic use of participatory tools in the last paper (Paper 3). The primary goal of this doctoral project is to theoretically explain and empirically validate the overlooked – yet consequential – role of bureaucracy and participation in contemporary policymaking. Through my findings from the three papers, I emphasize that bureaucratic structures and participatory governance can often act as significant catalysing forces, which delimit some policy paths, while nurturing others.
Tales of instability and decay: an integrable perspective

out-of-equilibrium dynamics

This thesis presents theoretical groundwork for the investigation of particular phenomena of instability and decay in out-of-equilibrium many body systems. By employing mathematical methods of integrability, we succeed in gaining new insights into problems not traditionally associated with an integrable realm.
The family of homogeneous sine-Gordon models provides a rare example of an integrable quantum field theory where both stable and unstable excitations are present in the spectrum. We studied the effect of unstable particles in different out-of-equilibrium settings and have shown that their presence is associated with specific signatures in many quantities of physical interest. Adopting the generalized hydrodynamic approach, we investigated the non-equilibrium dynamics following a quench and observed hallmarks of the creation and decay of unstable particles. Furthermore, we explored in considerable detail their quantitative and qualitative dependence on the parameters of the problem.
Decay processes due to environmental interactions are an experimentally relevant problem, yet the theory of open systems is substantially less developed than for their closed counterparts. We concentrate on Markovian open quantum systems described by a Lindblad time evolution equation and design a framework for analytic investigation of Lindblad dynamics via establishing a connection with integrability. We identify a number of Lindblad equations that can be mapped onto non-Hermitian interacting Yang-Baxter integrable models. The key ingredient of the proposed map is the structural similarity between the operators considered. We present examples of mappings between integrable Hamiltonians and Lindblad generators and underline several models of physical interest which can be investigated within this framework. By employing Bethe ansatz techniques, we study the dynamics of some of these models.
Political championship: understanding African state effectiveness and Sino-African infrastructure development

Keywords: Belt and Road Initiative

Why do Chinese-funded and -constructed projects that are similar in nature develop starkly different trajectories in different African states? This question sheds light on the varying state effectiveness in Sub-Saharan Africa. Diverging from existing structural explanations that stress the external agency and institutional argument that emphasizes bureaucratic capacity, I propose a political championship theory to explain variances in African states’ effectiveness to deliver functional infrastructure and policies. I argue that perceived threats from electoral competition generate strong political commitment from the state’s leadership, i.e. a political champion. When a political champion has high authority, their intervention in project implementation generates motivations for bureaucrats and tempers resistance, leading to higher project functionality. To empirically examine the political championship theory and two competing theories: the external agency and the bureaucratic capacity arguments, I trace the process of three Chinese-funded and -constructed railway projects: the Standard Gauge Railway in Kenya, the Addis-Djibouti Railway in Ethiopia, and the Caminho de Ferro de Benguela in Angola. I rely on 250 interviews conducted during 40 weeks of field research from 2017-2019 in Kenya, Ethiopia, Angola, and China. This research contributes to the theoretical debate on state effectiveness by emphasizing individual agency within structural and institutional constraints, a previously understudied area in state effectiveness. This research also challenges the conventional belief and shows that short-term electoral institutions can be as effective as long-term centralized ones in generating leadership commitment to developmental projects or policies. The thorough documentation of three Chinese-sponsored projects in Africa also fills the research gap of Chinese infrastructure projects in developing countries in general—despite its practical significance, limited empirical research studies have explored this subject due to the hard-to-access nature of Chinese actors and projects.
