Essays in empirical and theoretical labor market models
Keywords: Labor market model
Unemployment insurance
Banking models

Financial frictions
SVAR

This DPhil thesis is a collection of three theoretical and empirical papers studying labor markets in several advanced economies. Two chapters examine the relationship between the banking sector and the labor market in the US and the UK, while one evaluates a policy that has been proposed to help labor markets in the Euro Area adjust to economic shocks. In the first chapter, I develop a New Keynesian DSGE model that integrates a banking sector subject to moral hazard with a standard random search model of the labor market. I estimate the model using US data and study the role of the banking sector in determining labor market fluctuations. In the second chapter, I estimate a structural VAR model of the UK and US economies and identify bank lending shocks using a mix of sign and short-run exclusion restrictions. Consistent with the predictions of the DSGE model, an expansionary loan supply shock decreases job-destruction and increases job-creation, reducing the unemployment rate persistently. Bank lending shocks are also important drivers of labor market fluctuations, particularly during the Great Recession. Lastly, in the third chapter, I calibrate to the Euro Area a currency union DSGE model to evaluate the aggregate properties of European Unemployment Insurance (EUI). I find that EUI cannot contemporaneously stabilize the monetary union and achieve convergence in regional unemployment and inflation rates.
A high-fidelity microwave driven two-qubit quantum logic gate in 43Ca+
Keywords: two-qubit gate

Quantum computers offer great potential for significant speedup in executing certain algorithms compared to their classical counterparts. One of the most promising physical systems in which implementing such a device seems viable are trapped atomic ions. All of the fundamental operations needed for quantum information processing have already been experimentally demonstrated in trapped ion systems. Today, the remaining two obstacles are to improve the fidelities of these operations up to the point where quantum error correction techniques can be successfully applied, as well as to scale up the present systems to a higher number of quantum bits (qubits).
This thesis addresses both issues. On the one hand, it decribes the experimental implementation of a high-fidelity two-qubit quantum logic gate, which is the most technically demanding fundamental operation to realise in practice. On the other hand, the presented work is carried out in a microfabricated surface ion trap – an architecture that holds the promise of scalability.
The gate is applied directly to hyperfine "atomic clock" qubits in 43Ca+ ions using the near-field microwave magnetic field gradient produced by an integrated trap electrode. To protect the gate against fluctuating energy shifts of the qubit states, as well as to avoid the need to null the microwave field at the position of the ions, a dynamically decoupled Mølmer-Sørensen scheme is employed. After accounting for state preparation and measurement errors, the achieved gate fidelity is 99.7(1)%. In previous work, the same apparatus has been used to demonstrate coherence times of T&ast;2 ≈ 50 s and all single-qubit operations with fidelity > 99.95%.
To gain access to the "atomic clock" qubit transition in 43Ca+, a static magnetic field of 146G is applied. The resulting energy level Zeeman-structure is spread over many times the linewidth of the atomic transition used for Doppler cooling. This thesis presents a simple and robust method for Doppler cooling and obtaining high fluorescence from this qubit in spite of the complicated level structure. A temperature of 0.3mK, slightly below the Doppler limit, is reached.
Robert Jenson's Trinitarian reconstitution of metaphysics
Keywords: Metaphysics
Robert Jenson
Trinity
Time
Ontology

This thesis provides a critical examination of Robert Jenson’s doctrine of the Trinity, and the ways in which Jenson’s development of this doctrine corrects central aspects of contemporary metaphysics. Jenson's doctrine of the Trinity develops from his belief in the significance of the narrative form of Scripture, and the way in which the Christian Gospel addresses human religiosity. In order to explain this development, the thesis addresses some topics not addressed in scholarship on Jenson, especially his understanding of theological language and his approach to religious epistemology. It also describes the ways in which Jenson's theological project coheres with the task and method of contemporary metaphysics.
After describing Jenson's doctrine of the Trinity, the thesis moves on to address substantial critiques from George Hunsinger, David Bentley Hart, and Oliver Crisp. Hunsinger critiques Jenson on the ground of orthodoxy. He claims that Jenson’s views commit him to a number of heresies, both ancient and modern. David Bentley Hart also critiques Jenson for his perceived unorthodoxy, arguing that Jenson makes the world necessary for God, and makes God responsible for evil in a way which is at odds with the Christian faith. Oliver Crisp critiques Jenson's metaphysics on the grounds of coherence. The thesis provides responses to all of these critiques.
Following these critiques, the thesis describes the ways in which Jenson’s Trinitarianism reconstitutes certain central aspects of contemporary metaphysics, especially in the philosophy of time and fundamental metaphysics. Jenson argues on Trinitarian grounds that Christians ought to hold something akin to a moving spotlight view of time. He also argues that Christians ought to deny the category of substance and hold 'event' to be the primary category of metaphysics.
The thesis also highlights several weaknesses in Jenson's thought: he has no clear epistemology, his response to the problem of evil is inconsistent, and his work on 'being' is misdirected. None of these weaknesses are found to be fatal to Jenson's project, and the thesis offers suggestions for how each in turn could be corrected.
New approaches to the investigation of the interactions between enhancers and promoters during haemopoiesis
Keywords: Chromatin Conformation Capture

Next generation sequencing based methods allow us to identify active genes and potential regulatory elements rapidly across the genome, but an outstanding challenge is to unravel which regulatory elements control which genes. This is problematic because regulatory elements control genes over huge distances (over 1 million base pairs) and they have an unpredictable distribution around the genes they influence. In order to enhance transcription the protein complexes at distal regulatory elements make physical contact with the promoter. These interactions can be detected using Chromosome Conformation Capture (3C) technology and the position of regulatory elements can be deduced from these data. However, these methods are either low throughput or low resolution and they are prone to bias. In this 3C techniques were specifically developed to determine the interactions between regulatory elements and gene promoters promoter. The focus has been the development of Next Generation Capture-C, which allows many genetic loci and samples to be analysed simultaneously, with greater sensitivity and accuracy than has previously been possible. High resolution data can be produced from as few as 100,000 cells, and single-nucleotide polymorphisms can be used to generate allele-specific tracks. Nanostring technology has also been developed for analysis of 3C libraries, as this allows interaction profiles to be determined without PCR or sequencing bias. The Nanostring data show remarkable correlation with the interaction profiles generated by NG Capture-C.
A theology of disagreement
Keywords: Disagreement
Christian ethics
New Testament
Ethics
Biblical ethics
Ecclesiology
Church unity
Richard Hays
Moral theology

Even the most casual contemporary observer of Christianity must recognise that the notion of Christian community being identifiable through the mutual love of its members (John 13:35) is difficult to reconcile with the schismatic reality of current ecclesial life, dominated in the public sphere by divisive debates on matters such as gender or sexuality. Given the constant presence of disagreement throughout the church’s history, it remains an ethical subject neglected by scholars.
This study examines how New Testament texts might inform Christian approaches to disagreement. It is the first systematic consideration of disagreement as a New Testament theme; it follows, and critiques, the methodological approach of Richard Hays in The Moral Vision of the New Testament. The context is public disagreement among Christians: how the church speaks in public when facing its inevitable disagreements, and what theological and ethical concerns might inform how this speech proceeds.
The thesis is in three parts. Part One is an examination of the New Testament in relation to disagreement, following Hays' 'descriptive task'. In Part Two, the 'synthetic' and 'hermeneutical' tasks of Hays' methodology are critiqued and some modifications are proposed; a theology of disagreement that emerges from the New Testament is outlined.
Part Three considers some ecclesiological implications of this theology of disagreement. Following Hays' 'pragmatic task', it examines how moral theological insights from the New Testament interact with the life of the contemporary church. Illustrative examples consider the church's public theological witness, its pneumatology, and its liturgy, to demonstrate the need for a Christian ethic to engage with extra-Biblical authority with greater enthusiasm than Hays. The thesis concludes by affirming the particular value of reading the New Testament in pursuit of ethical wisdom, but without excluding insights from tradition, reason and experience. The challenge for the church is identified as a move Towards Loving Disagreement; an integral part of its mission is to disagree Christianly.

Begun in Berlin, completed in exile in Paris, and premiered on both sides of the Atlantic, Kurt Weill's Symphony No. 2 sets up the symphony circa 1933 as both resolutely international and messily interdisciplinary, and spotlights how fundamentally a transnational approach is needed in order more comprehensively to understand both the genre and the localised political and social issues shaping symphonic discourse at this time. Taking the issues raised by Weill’s symphony as a starting point, and borrowing fine-grained, historically synchronic approaches from year studies, this thesis examines the symphonic genre in 1933 through four other case-study works composed or premiered in that year. I thus position the symphony as a site of cultural exchange between and within the major contexts traversed by Weill and his work: Berlin, Paris, and a messier U.S. East-Coast nexus that centres on New York and Boston, via Mexico City, looking in detail at Hans Pfitzner's Symphony in C-sharp minor, Roy Harris's Symphony 1933, Aaron Copland's Short Symphony, and Arthur Honegger's Mouvement Symphonique nr. 3.
The Germanic genre has long been associated with nationalism, monumentality, and power display, wedded to Germanic Enlightenment philosophical discourses about universalised selfhood and its relationship to society. 1933, the year in which Hitler took power and the Great Depression reached its peak, was politically and economically fraught, concentrating social questions that intersect with symphonic issues about power, selfhood, space, and mass audiences. It is also a neglected year within symphonic surveys. The thesis combines archival work and hermeneutic perspectives to foreground those social and political discourses historically associated with the genre. I argue for the significance of their differing legacies in co-existent contexts, for the complicity of the genre in establishing and perpetuating political and colonial hegemonies, and for the urgency of rethinking the symphony as an international phenomenon.
Literature, language, and the human: a theoretical enquiry, with special reference to the work of F.R. Leavis
Keywords: Literature
Peter Lamarque
Martha Nussbaum
Human living
Charles Taylor
F.R. Leavis

This thesis proposes a theory of literature's human relevance in literary terms, developing hints in the critical practice of twentieth century literary critic F.R. Leavis. It examines how literary texts can be humanly relevant in a manner that depends on their literary merit, and does so in three stages, interrogating: the way literary texts operate; the role literary language plays in thinking; and the interaction of literature and morality. The thesis has two, related, aims: to reconceptualise literature's relation to human living, and to offer a recharacterisation of Leavis's literary criticism, with the investigation of aspects of Leavis's practice forming part of the more fundamental enquiry regarding the nature of literature's human significance. In the first stage, the thesis argues that Leavis's critical practice in his works of the 1930s (his first major decade of critical output) provides fruitful ways for conceptualising the interaction between form and meaning in literature, with important consequences for present-day understandings of how literature functions and how it matters. It focuses on an untheorised (by him or others) achievement in Leavis's criticism, the introduction of the term ‘attitude' into literary analysis and judgement, and argues that the term enables a different mode of attention to the question of how literature relates to the human world. The second stage first interrogates the role that language in general plays in understanding, constructing a hypothesis from arguments by philosophers R.G. Collingwood and Charles Taylor, and then turns to literary language, arguing that it enables a mode of relating to experience not otherwise possible, and forms a process of thinking, for reader and writer alike. The final stage focuses on arguments in aesthetics against literature's cognitive value, and in moral philosophy for its empathic and moral value. Building on earlier arguments about the operation of literary language and language's relation to thought, the thesis claims that literary language is humanly meaningful in a way that is both cognitively and morally significant. Throughout, the thesis argues for the inescapable link between well-written literature and the morally resonant, such that good literature forms what Taylor calls ‘moral sources'. The crucial query is how literature functions, which will help us better to answer why it is humanly important. This thesis engages with literary criticism, philosophical aesthetics and moral philosophy, as well as offering close readings of literature itself.
Novel device architectures for perovskite solar cells
Keywords: Device architecture
Perovskite
Energy yield

The aim of the work presented in this thesis is to study the opto-electronic properties of semi-conducting perovskite materials when being used in unconventional solar cell device configurations. Being a young technology, perovskites as solar cell materials have seen an unparalleled rise in the research community which has driven the fastest performance inflation to power conversion efficiencies competing with the ones of long established single crystalline technologies. The ability to process perovskites inexpensively makes them the new hope in the fight against climate change. Herein device architectures were developed with a special focus on potential commercial applications.
Initially the work in this thesis has been motivated by the interest in crystal growth and morphology of perovskite thin-films, which has led to the study of confined crystal growth within microstructures. Controlling the crystal domain geometry enabled the fabrication of enhanced semi-transparent devices. More efforts were directed into the improvement of specifically neutral colour semi-transparent devices, which could be improved via a simple treatment of selectively attaching shunt-blocking layers. Furthermore, a back-contacted perovskite device design was introduced, which allows not only for the fabrication of a new type of perovskite solar cell, but also represent a great material testing platform to study perovskite and electrode characteristics. This led to the discovery of charge transport distances, that exceed those of other thin-film devices.
Finally, perovskite-on-silicon tandem solar cell designs were analysed through a rigorous optical model to estimate the expected real world energy yield from such systems. Important implications include the fact that two terminal tandem solar cells come close to four-terminal configurations and can overall compete, in relative terms, well with established single junction silicon cells.
The social functions of intergroup schadenfreude
Keywords: Intergroup Relations
Schadenfreude
Social Psychology
Emotion

Schadenfreude is a German word, which describes the pleasure that people take in someone else’s misfortune. The aim of the present research was to investigate the social functions of intergroup schadenfreude. Chapter 2 presents Studies 1 – 3, focusing on the social functions of experiencing intergroup schadenfreude in the context of football tournaments, using both concurrent and retrospective methods. Study 1 did not find any relation between change in perceived relative status and intergroup schadenfreude, possibly because of the sample’s low domain interest and identification. However, schadenfreude was positively associated with change in status in Study 2 and with change in performance evaluation in Study 3 as expected. Also, across all three studies, intergroup schadenfreude was associated with consequences corresponding to its social distancing (e.g., distance from or dislike of the outgroup and intention to humiliate its members) and social affiliation functions (e.g., intention to celebrate with ingroup members). Importantly, schadenfreude mediated the effects of change in status (Study 2) and performance evaluation (Study 3) on these consequences. Chapter 3 presents Studies 4 and 5, which investigated whether social status is specifically associated with intergroup schadenfreude, and examined whether this social concern helps to differentiate intergroup schadenfreude from victorious joy (i.e., happiness about a third-party’s victory). I developed a new experimental paradigm to manipulate participants’ concern for status to elicit feelings of intergroup schadenfreude. I also manipulated participants’ concern for external rewards associated with the third-party’s victory to prompt victorious joy. However, in both studies, the concern for external rewards was the main influence on both intergroup schadenfreude and victorious joy, although a multivariate interaction between the two motives affected these emotions in Study 4. Hence, these studies suggest that status may be only one of the many motives underlying intergroup schadenfreude. Chapter 4 presents Study 6, which was a vignette-based study investigating the social affiliation functions of sharing intergroup schadenfreude as a function of ingroup identification. Participants read tweets from an ingroup member expressing either intergroup schadenfreude or victorious joy. Identification was also manipulated. However, results showed that recipients of intergroup schadenfreude messages formed more negative impressions of the tweeter and intended to distance themselves from him/her more than recipients of victorious joy messages. Chapter 5 provides an overview of the findings, contributions, and limitations of these six studies and discusses directions for future research. Overall, this thesis went beyond the current focus on the antecedents of schadenfreude and took steps towards the development of a social-functional account of intergroup schadenfreude.
The spatial organization of the epidermal growth factor receptor on the surface of colorectal carcinoma cells
Keywords: total internal reflection fluorescence microscopy

The discovery of the existence of the cell membrane has led to a search for its organization on a molecular scale. The advent of artificial lipid bilayers and the development of electron microscopy in the 1930’s provided direct visual evidence for the existence of the cell membrane and drove forward models of membrane structure based its known composition of proteins, lipids and carbohydrates. The fluid mosaic model of membrane structure, based on thermo- dynamics and newly developed protein structural studies of the time, placed integral globular membrane proteins within a fluid phospholipid bilayer. This model allowed for the association of proteins into groups and the possible mobility of proteins within the lipid bilayer. At the the same time fluorescence microscopy demonstrated movement of proteins in the plane of the lipid bilayer. Since then experimental techniques have been developed that show protein complexes of varying sizes do exist and so this gives us the opportunity to ask how receptor proteins fit into the molecular organization of the cell membrane.
This thesis presents an investigation into how the epidermal growth factor receptor (EGFR) organizes in the cell membrane of colorectal carcinoma cells. First a new cell line for studying the receptor by stably expressing the epidermal growth factor receptor conjugated to enhanced green fluorescent protein (EGFR-eGFP) in SW620 cells was developed. This is an interest- ing cell line because it originates from a colonic adenocarcinoma that during the process of metastasis has lost the ability to express the EGFR. It therefore provided an environment for the expression of the fluorescent form of the receptor more in keeping with its natural environment.
The technique of total internal reflection fluorescence (TIRF) microscopy was used to visualize the fluorescently tagged receptor in the cell membrane. This technique uses the principles of total internal reflection to excite fluorescence in molecules located only 100 nm into the cell. Because sources of fluorescence from outside the illuminated area are minimized individual fluorescent molecules can be imaged. The spots in the images, produced by the fluorophores, were detected using a single molecule detection and tracking algorithm. The intensities of these detected spots were analysed and compared with that from a single molecule of enhanced green fluorescent protein (eGFP). This gave an estimate of the number of receptors contained within each receptor complex.
Before ligand binding most of the receptors were found to be located in complexes containing up to eight molecules and most frequently they were found in complexes of two molecules. Larger complexes of receptors were found to have formed after activation of the receptor by its ligand.
