Experience, agency and the self

Wilfrid Sellars has made familiar a distinction between manifest and scientific images of man-in-the-world. The manifest image is 'a sophistication and refinement of the image in terms of which man first came to be aware of himself as man-in-the-world' ([2], p.18)/ and in its methodology 'limits itself to what correlational techniques can tell us about perceptible and introspectible events' (p.19). The scientific image, on the other hand, 'postulates imperceptible objects and events for the purpose of explaining correlations among perceptibles.' (ib.) This thesis is centred on a consideration of two difficulties facing anyone who takes the manifest image seriously as an autonomous image of man. In chapter 1 I consider the connection between perception and its objects, and argue that there is a disharmony between the manifest and scientific accounts of this connection. But I also suggest that the manifest image, which incorporates a certain Cartesianism or internalism, cannot lightly be dispensed with in our understanding of the nature of experience. Chapter 2 is a companion piece to chapter 1: in it I argue that the manifest view of experience accords a certain metaphysical priority to secondary over primary qualities in the constitution of any world capable of being experienced; I also suggest that the scientific image is dependent on the manifest image/ and so cannot subvert it. In chapter 3 I turn to the other main area of difficulty: freedom. I argue that free will as the incompatibilist contrues it is constitutive of the time-order; but that it carries with it implicit internal contradictions. The conflict here lies within the manifest image; the scientific image discerns no such freedom/ and so incurs no such problems. But if I am right that freedom constitutes time/ it will not be an option for us to disembarrass ourselves of the contradictions. I also argue that there is a relation of mutual dependence between freedom/ incompatibilistically construed/ and internalism. The manifest image as a whole - deeply problematic as it is - is therefore grounded in and entailed by something quite ineluctable/ namely the reality of the time-series. This is the principal conclusion of the thesis. If I succeed here/ I provide support for the claim that our difficulties with the manifest image cannot be solved by abandoning it: the manifest image/ problems and all/ must just be lived with. The remainder of the thesis explores topics related to this main thrust. Chapter 4 is really an appendix to chapter 3; it shows how no parallel difficulties attend the constitution of experiential space/ because space is (unlike time) not transcendental. In chapter 5 I examine the commitments of the notion of the transcendental self/ whose existence was deduced in chapter 3 as a condition of freedom. In particular, I aim to show how that self inherits some of the difficulties of its parent concept of freedom; but also how a distinction between transcendental and empirical components in the self can help us with the problem of privacy.
Mors immatura: portraits of children on Roman funerary monuments in the west

This thesis examines funerary iconography for evidence of Roman attitudes towards children, childhood and the family. Based on 690 portrait monuments drawn from select areas of the Western Empire, its central hypothesis is that the commemorations are best read as highly artificial constructs which reveal more about the social preoccupations of the commissioners than the lives of the children whom they represent.
The first of the seven chapters defines the parameters of the accompanying catalogue and discusses the benefits of studying a diverse range of monuments (rather than isolated "show-pieces"). The methodological section which follows assesses the cultural limitations and identification problems inherent to funerary material and considers how the terms "child" and "portrait" are best defined in this medium. The four subsequent chapters analyse the following key areas: the ages, genders and attributes of children; the presentation and composition of the family; the iconography of surrogate and extended relationships; and the archaeological context of funerary display. In each case any emotional interpretations which surround the material are discussed and then countered with alternative, and better supported, social readings. It is argued that previous research has been based on samples which are too limited in terms of size, genre and geographical scope and influenced too heavily by a desire to prove parental benevolence and the existence of "love" and "affection" within the Roman household. By exposing demographic biases and iconographic problems, it is shown that commissioners were actually using the image of the child for overtly social purposes, with some of the results being subject to substantial, and hitherto unacknowledged, regional variation. The conclusion then reassesses a well-known example to show that while Roman parents did attach importance to their children, funerary evidence can only prove it to be of a social, rather than an emotional, nature.

Multi-hop localization in cluttered environments

Range-based localization is a widely used technique for position estimation where distances are measured to anchors, nodes with known positions, and the position is analytically estimated. It offers the benefits of providing high localization accuracy and involving simple operation over multiple deployments. Examples are the Global Positioning System (GPS) and network-based cellular handset localization. Range-based localization is promising for a range of applications, such as robot deployment in emergency scenarios or monitoring industrial processes. However, the presence of clutter in some of these environments leads to a severe degradation of the localization accuracy due to non-line-of-sight (NLOS) signal propagation. Moreover, current literature in NLOS-mitigation techniques requires that the NLOS distances constitute only a minority of the total number of distances to anchors.
The key ideas proposed in the dissertation are: 1) multi-hop localization offers significant advantages over single-hop localization in NLOS-prone environments; and 2) it is possible to further reduce position errors by carefully placing intermediate nodes among the clutter to minimize multi-hop distances between the anchors and the unlocalized node. We demonstrate that shortest path distance (SPD) based multi-hop localization algorithms, namely DV-Distance and MDS-MAP, perform the best among other competing techniques in NLOS-prone settings. However, with random node placement, these algorithms require large node densities to produce high localization accuracy.
To tackle this, we show that the strategic placement of a relatively small number of nodes in the clutter can offer significant benefits. We propose two algorithms for node placement: first, the Optimal Placement for DV-Distance (OPDV) focuses on obtaining the optimal positions of the nodes for a known clutter topology; and second, the Adaptive Placement for DV-Distance (APDV) offers a distributed control technique that carefully moves nodes in the monitored area to achieve localization accuracies close to those achieved by OPDV. We evaluate both algorithms via extensive simulations, as well as demonstrate the APDV algorithm on a real robotic hardware platform.
We finally demonstrate how the characteristics of the clutter topology influence single-hop and multi-hop distance errors, which in turn, impact the performance of the proposed algorithms.

Changing pattern of household expenditure on health and the role of public health insurance schemes for the poor in India: case of Rashtriya Swasthya Bima Yojana

Background: In order to protect the poor from health shocks, the Government of India launched Rashtriya Swasthya Bima Yojna (RSBY) in 2008. The objectives of this study are: a) to assess the changes in the financial burden of health care on the poor population; b) to estimate the effects of RSBY in reducing the financial burden on the poor; and c) to examine the impact of RSBY on the labour supply of the poor.
Methods: The study is based on data from the National Sample Survey Organisation (NSSO). The sample size is between 100-125 thousand households at the all-India level. The study uses pooled cross-section regression analysis to assess the changing pattern of out-of-pocket (OOP) payments on healthcare. The impact of RSBY on financial risk protection and labour force participation rate in India were estimated using the difference-in-differences (DID) method.
Findings: My thesis consists of three papers. The findings in the first paper, changing pattern of out-of-pocket payments, reflect that the poorest 20% of households, compared to the richest 20%, realised a slower increase in out-of-pocket as a share of the household’s total expenditure (-0.5%) and catastrophic payments (-2%) during the period of 2000-2012. However, during the same period, Scheduled caste/tribe and Muslim households reported an increased burden of out-of-pocket.
The second paper finds reduction in the probability of incurring ‘any inpatient expenditure’ and ‘catastrophic inpatient expenditure’ after RSBY intervention but marginal increase in the ‘per person monthly inpatient expenditure’ and insignificant change in ‘inpatient expenditure as a share of households’ total expenditure’. The effects of the scheme on the total out-of-pocket payment are negligible and non-drug expenditure reflected significant increase.
The third paper finds that women’s labour supply increased (3% per annum) but the elderly labour supply declined (1.5%). Further, men switched from self-employment to casual work while women moved to wage-paid regular and casual jobs at the cost of being self-employed.
Discussion and conclusion: The poor and other less advantaged population groups realised an increasing OOP burden mainly on account of two factors: i) outpatient care is not covered under RSBY; and ii) the benefit package under the scheme is very modest. Women’s labour supply increased and the elderly labour supply declined in favour of leisure because of possible improvements in health. However, the overall labour supply did not change. The Indian government needs to consider broadening the benefit package and including outpatient coverage under RSBY.

Flexoelectric and dielectric phenomena in helicoidal liquid crystals

The unique features of flexoelectric and dielectric effects are investigated, and exploited for a variety of functions, in a wide range of helicoidal liquid crystal systems, including non-chiral, cholesteric and blue phases.
Electrooptic techniques are developed to measure flexoelectric parameters in non-chiral and cholesteric liquid crystals using twisted nematic and Grandjean geometries respectively. A crystal rotation method, and using a lock-in amplifier, is used to enable the measurement of a very small e/K of 0.011 C/N-1m-1.
Enhancement in chiral-flexoelectric switching is demonstrated theoretically in liquid crystals with negative dielectric anisotropy and in systems in which the pitch is constrained to be other than the natural pitch.
A methodological framework for inducing stable Uniform Lying Helix alignment is developed based on weak homeotropic alignment conditions and a method to bias the helicoidal axis orientation; a series of approaches within this framework are demonstrated, including nano-grooved interfaces, periodic boundaries conditions, in-plane fields, and mould-templated micro-channels. The latter approach is potentially commercially viable for sub-millisecond electrooptic technology.
The contribution to a cholesteric material's effective dielectric permittivity of flexoelectric polarization is formulated, and an ability to switch a cholesteric between Grandjean and lying-helix configurations based on the dispersion in the flexoelectric polarization and resultant relaxation in dielectric properties is demonstrated. The flexoelectric contribution to dielectric permittivity is exploited to enable switching in bistable reflective displays and alignment of the Uniform Lying Helix.
The existence of a flexoelectric contribution to Kerr switching in blue phases is demonstrated, and a semi-empirical model for the effect is developed. The effect is the first known example of a non-polar flexoelectrooptic effect. Independent flexoelectric and dielectric contributions to Kerr switching in blue phases are measured experimentally by measuring the induced birefringence as a function of driving frequency in flexoelectric- and dielectric-dominated wide-temperature-range blue phase materials.

Eugenics and Christian mission. Charitable welfare in transition: London and New York, c. 1865–1940.

In this thesis it is argued that a full and complete understanding of the eugenics movement may only be gained by examining those who were implicated in its criticisms.
Using the example of three Christian missionary organisations that worked amongst largely poor and immigrant communities in London and New York, it is demonstrated that eugenics was a pervasive ideology outside its 'official' societies.
Moving away from an understanding grounded in ideas of conflict and concession, it will be demonstrated that those whose work was challenged by eugenic claims were able to interpret the ideology according to their existing reformist agendas. Hereditarian ideas did not sound the death knell for reformers, and these organisations demonstrated both the willingness and capacity to shape eugenic ideas within and outside their organisations.
From these examples it is argued there is a need to move beyond definitions of eugenics that limit the movement to a small subset of its methods. Far from being a peripheral aspect to the history of eugenics, it will be seen that these missionary agencies occupied a position at the centre of eugenicists' concerns. As prominent providers of charity, a work charged by eugenicists with unnaturally hindering the natural laws of selection, religious communities were, in part, one of the reasons that eugenics was deemed necessary in the first place.
This picture is confirmed by an examination of two eugenics societies, one on each side of the Atlantic, where the impact of religious sentiment and ideas exerted a dramatic effect upon policies and propaganda work.
There was no one-way flow of ideology from eugenicists towards reformers, but rather a two-way dialogue which created a marked impression on both groups.

On-line nuclear orientation studies of neutron deficient Te, I and Cs isotopes

On-line nuclear orientation at low temperature has become an important technique for the study of nuclei far from stability, through measurements of nuclear moments and other quantities of spectroscopic interest.
The theory of low temperature nuclear orientation and its application to the study of nuclear structure are reviewed. Of particular importance to the on-line measurement, in which a wide range of short-lived nuclei are available for study, is the question of how fast these nuclei can be cooled to the lattice temperature, and thus oriented. To address this, the theory of nuclear spin-lattice relaxation, relevant to the online technique, is outlined. In particular, quantitative methods to deal with cases in which the spin-lattice relaxation time is comparable with the isotope half-life have been developed and applied.
One of the major current interests in nuclear structure physics is to investigate how the neutron-proton interaction influences the structure of nuclei that are transitional, between well established regions of spherical and deformed nuclei. In such nuclei, intruder excitations, which signal the onset of deformation, are observed low in energy. Using the Daresbury on-line isotope separator, an extensive study of the decay of 118I to 118Te has been performed using nuclear orientation techniques, combined with γ - γ and conversion electron spectroscopy measurements. Interpretation of the results obtained for 118Te within the framework of IBM-2, gives strong evidence for the existence of such an ,em>intruder
configuration in this nucleus.
On-line experiments have also been performed in which a range of neutrondeficient Cs nuclei has been oriented for the first time. In these measurements the hyperfine field of CsFe has been determined as (+)40.8(7) T, and also the Korringa constant for the system 121CsmFe has been measured (using a new technique) to be Ck = 0.059(l6)sK. These results have been applied to the case of 118Csm, for which the magnetic moment has been measured to be 5.4(1.1)nm. This large value clearly indicates the presence of the [404]9/2 orbital, which provides further evidence for the existence of intruder states in this region.

Mineralisation, Greisenisation and kaolinisation at Goonbarrow china clay pit, Cornwall, U.K

Goonbarrow, a China Clay pit situated within the St. Austell granite China Clay region, is the subject of a varied geochemical and isotopic study to determine the mode of genesis of the kaolinite and associated tin/tungsten mineralisation. Detailed geological mapping in conjunction with a geochemical study of the micas indicated that Goonbarrow is situated at the junction of the petrographically distinct phases of the St. Austell granite. An unusual assymmetric curved-feldspar-crystal pegmatite is found at the junction. Elvans at Goonbarrow and three other locations within the St. Austell granite are shown to be intruded during hydrothermal activity and in some cases after major vein formation. Three main types of vein were recognised in Goonbarrow, the major ones being spatially associated with zones of kaolinised granite. A potassium/ argon age study showed that the granites, pegmatite and greisens (and by inference tin/tungsten mineralisation) were formed at about 280 ±10 m.y. Four elvans, including Goonbarrow, were dated at around 272 m.y. Three of these elvans crosscut major vein, swarms. Age determinations on fine grained muscovite produced predominantly during kaolinisation and several kaolinised potassium feldspars also gave Hercynian eges. Scanning electron microscopy studies on daughter minerals in fluid inclusions indicated the presence of Al, As, Ca, Cl, Cu, Fe, K, Kg, Mn, Na, S, Sn and Zn although many of these elements were not present in minerals in the pit. Temperatures, pressures and salinities of vein fluids were determined by conventional fluid inclusion studies, which also indicated that the veins vere boiling. Hydrogen and oxygen isotope studies on vein quartz and greisen muscovites coupled with a re-interpretation of previous work and the fluid inclusion study produced a new model for the genesis of Cornish China Clay. Kaolinite genesis from the vapour phase of hot boiling fluids intimately associated with greisen bordered quartz/tourmaline veins of Hercynian age is favoured.

Light scattering from ultracold atomic gases

Systems of ultracold atoms in optical potentials have taken a place at the forefront of research into many-body atomic systems because of the clean experimental environment they exist in and the tunability of the system parameters. In this thesis we study how light scattered from these ultracold atomic gases reveals information about the state of the atomic gas and also leads to changes in that state.
We begin by investigating the angular dependence of light scattered from atoms in optical lattices at finite temperature. We demonstrate how correlations in the superfluid and Mott insulator states affect the scattering pattern, and we show that temperature affects the number of photons scattered. This effect could be used to measure the temperature of the gas, however, we show that when the lattice band structure is taken into account the efficiency of this temperature measurement is reduced.
We then investigate light scattering from small optical lattices where the Bose-Hubbard Hamiltonian can be solved exactly. For small lattices, scattering a photon from the atomic system significantly perturbs the atomic system. We develop a model of the evolution of the many-body state that results from the consecutive scattering and detection of photons. This model shows that light scattering pushes the system towards eigenstates of the light scattering measurement process, in some cases leading to a superposition of atomic states.
In the second half of this thesis we study light scattering that depends on the internal hyperfine spin state of the atoms, in which case the scattered light can form images of the spatial atomic spin distribution. We demonstrate how scattering spatially correlated light from the atoms can result in spin state images with enhanced spatial resolution. We also show how using spatially correlated light can lead to direct measurement of the spatial correlations of the atomic spin distribution.
We then apply this theory of spin-dependent light scattering to the detection of different spin states of ultracold gases in synthetic magnetic fields. We show that it is possible to distinguish between ground states in the quantum Hall regime using light scattering. Moreover, we show how noise correlation analysis of the spin state images can be used to identify the correlations between atoms and how a variant on phase-contrast imaging can reveal the relationship between the atomic spins.
