Optimal policy and inconsistent preferences: behavioural policymaking and self-control
Keywords: habits
willpower
intertemporal choice
policy design
self-control
consumption
preferences

This thesis takes three different perspectives, using theoretical and experimental techniques, on time-inconsistent preferences and how the existence of multiple selves can affect both consumer behaviour and policy design. Across domains such as retirement saving, health, and educational achievement, intertemporal choice presents a challenge for both individuals and policymakers.
The first paper, 'Choosing When to Nudge: Designing Behavioural Policy around Decision-Making Costs,' considers how behavioural policy, which has proven increasingly popular with policymakers, affects welfare. I find that for present-biased consumers, behavioural policies help some consumers but can inefficiently discourage others from optimizing. Such policies therefore have an ambiguous effect on welfare, and similar to traditional policies, can impose equity-efficiency tradeoffs. Monopolies may increase welfare given their incentive to simplify consumer decisions instead of exploit switching costs.
The second paper, 'Virtue and Vice with Endogenous Preferences,' considers behaviour when preferences are affected by consumer decisions. I introduce agents whose temptation to consume in the present is affected by how much they choose to save for the future. I find that differences between agents can trap them in divergent paths of self-improvement -- saving more, they value the future more, making saving optimal -- or binging -- consuming more makes them indifferent to future costs, making consumption optimal. At the extreme, it is frequently an optimum for a consumer to consume their entire wealth.
The final paper, 'Bet You Can't Eat Just One: Consumption Complementarity and 'Self'-Control' considers an intrapersonal game between a moderate cold self and a hot self that wants to indulge. In equilibrium, sophisticated selves best respond to each other's behaviour: the cold self over-abstains and the hot self over-indulges to avoid inducing the other state. I test these ideas in the lab, and find that subjects on a diet who were induced to consume a piece of chocolate before the experiment indulge more in chocolate during the experiment, even when the initial indulgence was imposed by the experimenter. Eating a piece of chocolate, this suggests, can induce a period during which chocolate is more appealing.

This thesis aims to engage with the poetry of Scotland and Greek-speaking Cyprus, and examine the relationship between poetry defined as high culture and articulations of national identity in the two places. Scotland and Cyprus share characteristics that make the establishment of a single, coherent national identity with the appearance of permanence challenging, including their relationships with culturally dominant neighbours, competition between local and official languages, and the insecurity of their status as nations.
Both Scotland and Cyprus have historically had hybrid identities; in Scotland, British identity is made problematic by England's cultural dominance, while in Cyprus Greek-speakers have a conflicted relationship with Greece. This is made more complex by the fact that Scotland's political union with England may be ending, while Cyprus is divided in half as a result of tensions between Christian and Muslim populations and the unsubtle past involvement of Greece and Turkey in the island's affairs. This thesis aims to locate trends of national identity through the analysis of poetry and its reception in three distinct contexts. Part 1 analyses the evolution of Scottish and Greek-speaking Cypriot 'national character' through the poetry of national poets Robert Burns and Vasilis Michailidis, and the poets Walter Scott and Dimitris Lipertis.
Part 2 explores the effects of modernity on the expression of national identities in literature through the lens of the Modernist movement, and how this was adopted and modified in Scotland and Cyprus. This is discussed with reference to three poets, Hugh MacDiarmid, Kostas Montis and Edwin Morgan, and their treatment of the national past and search for a national literary language. Finally, Part 3 analyses deliberate engagements of poets with national identity and issues of national importance, using Seamus Heaney's idea of 'adequate' poetry as a guide. Two functions of poetry are considered: the role it can play in transforming the landscape into the national homeland, and its potential to address communal trauma, and transform it into a unifying experience.
Biophysical studies of membrane protein structure and function

Membrane proteins play a key role in numerous physiological processes such as transport, energy transduction in respiratory and photosynthetic systems, and signal transduction, and are of great pharmaceutical interest, comprising more than 60% of known drug targets. However, crystallisation of membrane proteins, and G protein-coupled receptors (GPCRs) in particular, still relies heavily on the use of protein engineering strategies, which have been shown to hamper protein activity. Here, a range of biophysical methods were used to study the structure and function of two membrane proteins, a prokaryotic peptide transporter, PepTSo and a GPCR, neurotensin receptor 1 (NTS1), using different membrane reconstitution methods to study the proteins in a native-like environment. Firstly, using the pulsed electron paramagnetic resonance (EPR) method of double electron-electron resonance (DEER) the conformation of PepTSo reconstituted into lipid bilayers was assessed and compared to previous structural data obtained from crystallography and modelling. The influence of the membrane potential and the presence of substrate on the conformational heterogeneity of this proton-coupled transporter were investigated. Secondly, NTS1 purification was optimized for biophysical study. Cysteine mutants were created and a labelling protocol was developed and optimized for fluorophore and nitroxide labelling studies. NTS1 was then studied by continuous-wave EPR, to assess the influence of ligand on local protein dynamics, and to assess the structure of a receptor segment known as helix 8, that was proposed to be an α-helix, but was only observed to be helical in one of the NTS1 crystallographic studies. Ensemble and single-molecule Förster resonance energy transfer (FRET), and DEER were combined to study the dimerisation behaviour of NTS1, showing novel dynamics of the interfacial associations. Finally, the signalling mechanism of NTS1 was also investigated using microscale thermophoresis (MST) to assess the affinity of the receptor for G protein in vitro in the absence of ligand, or in the presence of agonist or antagonist. MST measurements were performed in detergent and in nanodiscs of different lipid compositions, to assess the influence of the lipid environment on receptor function. In summary, this thesis demonstrates the potential of biophysical techniques to study various aspects of membrane protein structure and function in native-like lipid systems, complementing e.g. structural data obtained from crystallographic studies with functional data for membrane proteins in more native environments, as well as shedding light on protein dynamics. The work presented here provides novel insights into PepTSo transport, and in particular into NTS1 structure, signalling, and oligomerisation, opening up several avenues for future research.
Penelope: a study in the manipulation of myth
Keywords: Penelope
Hellenistic poetry
Greek tragedy
Augustan poetry
Homer

Mythological figures play a number of roles in literature: they may, of course, appear in person as developed characters, but they may also contribute more indirectly, as part of the substratum from which rhetorical argument or literary characterisation are constructed, or as a background against which other literary strategies (for example, the rewriting of epic or the appropriation of Greek culture by the Romans) can be marked out. This thesis sets out to examine the way in which the figure of Penelope emerges from unknown origins, acquires portrayal in almost canonical form in Homer's Odyssey, and then takes part in the subsequent interplay of Homeric and other literary allusions throughout later Classical literature (with chapters focusing particularly on fifth-century Greek tragedy, Hellenistic poetry, and Augustan poetry). In particular, it focuses on the manner in which, despite the potential complexities of the character and the possible variants in her story, she became quintessentially a stereotypical figure. In addition to considering example where Penelope is evoked by name, a case is also made for the thesis that allusion, or intertextual reference, could also evoke Penelope for an ancient audience. A central point of discussion is what perception of Penelope would be called to mind by intertextual reference. The importance of approaching relationships between ancient texts in intertextual terms rather terms of strict "allusion" is thus demonstrated. The formation of the simplified picture is considered in the light of folk-tale motifs, rhetorical simplification of myth, and favoured story patterns. The appendices include a summary of the myth of Penelope with all attested variants, and a comprehensive list of explicit references to her in classical literature.
Under Mount Roraima: the revitalization of a shamanic landscape and practice
Keywords: Guyana
shamanism
Amerindian
spiritual ecology

Humans have unique capacities to enhance and degrade landscapes. Many indigenous peoples embody conceptual systems that perceive, value and interact within landscapes differently than capitalist models of conservation and development. This thesis examines the spiritual ecology of the circum-Roraima landscape atop the Guiana Shield in South America. An extensive interdisciplinary literature review contextualizes primary data collected during 15 months of multi-sited ethnogeographic fieldwork among Pemon and Ka'pon members of the Carib linguistic family. Data in the form of narratives are interpreted within the theoretical framework of landscape that links subfields of historical, spiritual and political ecology. A detailed research program designed to collect qualitative emic data draws methods from ethnography, ethnoecology, historical ecology, grounded theory and decolonizing methodologies. An analysis of the adaptive capacities of situated spiritual ecological knowledge and practices is an important component of this research, since this dimension of landscape is often neglected in conservation and development studies. Ultimately, the project documents and analyzes endangered knowledge systems, reveals new historical details of the syncretic Areruya highland revitalization movement and articulates a shamanic land ethic.
Modelling the transition from channel-veins to PSBs in the early stage of fatigue tests
Keywords: fatigue
plasticity
multi-scale analysis
persistent slip bands
dislocations

Dislocation channel-veins and persistent slip bands (PSBs) are characteristic dislocation configurations that are of interest to both industry and academia. However, existing mathematical models are not adequate to describe the mechanism of the transition between these two states. In this thesis, a series of models are proposed to give a quantitative description to such a transition. The full problem has been considered from two angles.
Firstly, the general motion and instabilities of arbitrary curved dislocations have been studied both analytically and numerically. Then the law of motion and local expansions are used to track the shapes of screw segments moving through channels, which are believed to induce dislocation multiplication by cross-slip.
The second approach has been to investigate the collective behavior of a large number of dislocations, both geometrically necessary and otherwise. The traditional method of multiple scales does not apply well to describe the pile-up of two arrays of dislocations of opposite signs on a pair of neighbouring glide planes in two dimensional space. Certain quantities have to be more accurately defined under the multiple-scale coordinates to capture the much more localised resultant stress caused by these dislocation pairs. Through detailed calculations, one-dimensional dipoles can be homogenised to obtain some insightful results both on a local scale where the dipole pattern is the key diagnostic and on a macroscopic scale on which density variations are of most interest. Equilibria of dislocation dipoles in a two-dimensional regular lattice have been also studied. Some natural transitions between different patterns can be found as a result of geometrical instabilities.
Music, dances, and videos: identity making and the cosmopolitan imagination in the southern Philippines

This ethnography examines the processes in which rooted but overlapping forms of cosmopolitan engagements implicate the Tausug imagination of collectivity. It investigates Tausug expression of connection and belonging as they find themselves entangled into global cultural flow and caught up in the state and secessionist politics of attachment. Utilising methodological and theoretical approaches engendered by visual and material anthropology, the ethnography locates rooted cosmopolitan imagination in the works and lives of creative but marginalised and often silenced Tausug cultural agents engaged in street-based production, circulation, and consumption of popular music and dance videos on compact discs. The ethnography follows these cosmopolitan expressions as they are being imagined, embodied, reproduced, and shared by and across Tausug communities in the Zamboanga peninsula, the Sulu archipelago, and beyond through the digital spaces of the internet and cross-border flow of the videos. How the translocality of imaginaries reflected on the videos play out in everyday life and the broader politics of representation are demonstrated here as vital to the understanding of Tausug imagined community as an open, flexible, and dynamically engaging Muslim society despite long-standing political turbulence and economic uncertainty in their midst. Saliently, the thesis argues that Tausug cosmopolitanism cannot be reduced into a phenomenon driven by the expansive currents of Western-led globalisation. Rather, Tausug cosmopolitanism constitutes both continuity of and departure from past forms of translocal connections of Zamboanga and Sulu, which as a region was once integrated to a pre-colonial Southeast Asian emporium and continually through varying ways of connectedness. Old and new global processes come into play in shaping the everyday production of Tausug imaginaries inevitably rendering Tausug identity formation as a trajectory rather than an unchanging fact of being. Drawing from the Tausug ethnographic experience, the thesis contends that rooted cosmopolitanism does not necessarily constitute a singular condition but rather a contested and distinctively multifaceted phenomenon.

Usulism

This thesis delineates the transformation of Iran’s so-called post-revolutionary ‘religious intellectuals’ (rowshanfekran-e dini) from ideological legitimators within the political class of the newly-established theocratic-populist regime to internal critics whose revised vision for the politico-religious order coalesced and converged with the growing disillusionment and frustration of the ‘Islamic left’, a constellation of political forces within the governing elite of the Islamic Republic, that following the death of Ayatollah Khomeini increasingly felt itself marginalised and on the outskirts of power.
The historical evolution of this complex, quasi-institutionalised and routinized network, encompassing theologians, jurists, political strategists and journalists, which rose to prominence in the course of the 1990s, and its critical engagement with the ruling political theology of the ‘guardianship of the jurist’, the supremacy of Islamic jurisprudence, political Islamism and all forms of ‘revolutionary’ and ‘utopian’ political and social transformation, are scrutinised in detail. In this vein, the thesis examines the various issues provoked by the rowshanfekran-e dini’s strategic deployment and translation of the concepts and ideas of a number of Western thinkers, several of which played a pivotal role in the assault on the ideological foundations of Soviet-style communism in the 1950s and 1960s.
It then moves to show how this network of intellectuals and politicos following the election of Mohammad Khatami to the presidency in May 1997 sought to disseminate their ideas at the popular level by means of the press and numerous party and political periodicals, and thereby achieve ideological and political hegemony. The thesis proceeds to demonstrate the intimate connection between the project of ‘religious intellectualism’ and elite-defined notions of ‘democracy’, ‘electoral participation’, ‘reform’ and ‘political development’ as part of an effort to accumulate symbolic capital and assert their intellectual and moral leadership of the polity.
European gender equality under and after State Socialism: legal treatment of prostitution in the Czech Republic
Keywords: post-communism
post-socialist transition
gender equality
prostitution

The thesis looks at the legal responses to prostitution in Czechoslovakia and the Czech Republic under State Socialism and in Transition, and the understanding of gender equality therein. It argues that both, the legal regimes and the understandings of prostitution, varied between these periods. Under State Socialism, professional prostitutes were criminally liable under provisions on parasitism. In Transition, the ‘boom’ of prostitution after 1989 lead to the adoption of containment provisions, the violation of which results in fines for prostitutes. While being repressive toward prostitute as a work-shirker, the Socialist State, inspired by Marxist ideology, had aspirations to eliminate prostitution, which it saw as exploitation of women. Policy influencing actors in Transition, on the other hand, have become resigned to its existence. Prostitution has been seen as pathological but inevitable. As prostitutes have been mostly considered agents making free choice, they have been treated as legitimate objects of containment, state regulation and control. Gender equality, it is argued, was insufficiently considered during both periods. Because feminists (the sex-work and the sexual domination positions) fundamentally disagree about the best legislative regime, the thesis chose to work with the standard of ‘well-being of the prostitute’. At least, this requires for prostitutes not to be treated worse than procurers or clients, for example with regards to administrative, health or criminal obligations and liability. The thesis argues that State Socialism as well as Transition failed this minimal test – both regimes are marked by an absence of feminist analysis of the phenomenon of prostitution and a legal conceptualization of it as a gender equality issue.
Physics of microorganism behaviour: motility, synchronisation, run-and-tumble, phototaxis.
Keywords: Hydrodynamics
synchronisation
microorganism motility

Microorganisms have evolved in a low Reynolds number environment and have adapted their behaviour to its viscosity. Here, we consider some features of behaviour observed in microorganisms and use hydrodynamic models to show that these behaviours emerge from physical interactions, including hydrodynamic friction, hydrodynamic interactions and mechanical constraints.
Swimming behaviour is affected by surfaces and observations of Vibrio cholerae show that it swims near a surface with two distinct motility modes. We develop a model which shows that friction between pili and the surface gives the two motility modes. The model is extended to study the behaviour of bacteria which are partially attached to a surface. Observations of Shewanella constrained by a surface show several different behaviours. The model shows that different degrees of surface constraint lead to different types of behaviour; the flexibility of the flagellar hook and the torque exerted by the flagellar motor also cause different behaviours. Near surface behaviour is important for understanding the initial stages of biofilm formation.
Chlamydomonas swims using synchronous beating of its two flagella. A simple model of Chlamydomonas is developed to study motility and synchronisation. This model shows that the stability of synchronisation is sensitive to the beat pattern. Run-and-tumble behaviour emerges when we include intrinsic noise, without the need for biochemical signalling. The model is also used to show how observed responses of the flagella to light stimuli produce phototaxis. Finally we study hydrodynamic synchronisation of many cilia and consider the stability of metachronal waves in arrays of hydrodynamically coupled cilia.
This thesis shows that physical interactions are responsible for many behavioural features and that physical models provide a useful technique for exploring open questions in biology.
