A technique for acquiring spectral line data using a multi-aperture telescope is described. The multi-aperture principle and the criteria which led to the selection of a dispersive spectrometer are discussed. The problem of linking telescope and spectrometer has been solved by incorporating low loss optical fibres and this is also discussed. The problems of automatic data collection, its manipulation, display and storage presented a major research effort which were largely overcome by the use of cheap, digital micro-computers. To achieve rapid and flexible data handling the i.E.E.E. bus was used as the communication medium between control and data collecting micro-computers. In particular a non-standard approach was adopted when implementing specialised interrupt handling routines to deal with data communication, an aspect which forms the central theme of this thesis and is described in chapters three to five inclusive. A discussion relating to data obtained using the system in single fibre mode and to RPCS data obtained at intermediate resolution is presented in chapters six and seven respectively. The former permitted a preliminary determination to be made of both system resolution and the approximate integration times required to undertake a program of stellar emission line work. This is complimentary to that described in the final chapter which discusses the spectra of emission line stars, some of which are accompanied by circumstellar 'shells'. For pre-main sequence stars these shells may ultimately provide conditions favourable for the formation of planetary systems. There are examples of these types of stars to be found in the Northern hemisphere and which are within the detection limit of the system described in this thesis.

This thesis describes a study of power and power relations, which is developed through an exploration of the literature and professional discourse in an abductive research strategy The focus is provided by services for people with learning disabilities within one English County and the relationships that are produced within the processes that surround care planning. The study sets out to describe and to provide evidence for the proposition that welfare professionals and the organisations in which they are embedded set out to manufacture trust. This trust has a particular quality as it is impersonal and therefore does not require knowledge of any individual involved. At the same time this trust serves as a commodity within the competitive environment of welfare and it is contested - hence the politics of trust. The study defines trust as the reduction of complexity and the management of expectations. It uses a framework developed from the work of Michel Foucault and his followers’ relating to the relationship between power and discourse and the concept of governmentality. The study describes the local relations of power within which both organisations and the people to whom they provide services become fixed. At the same time it links a developing discourse of citizenship concerning people with learning disabilities with a discourse of trust that is articulated by professionals within organisations. However, organisations tend to promote sets of relationships between the individual and the community, which produce differing forms of citizenship dependent upon the discursive structure of the organisation. The existence of differing discursive structures between organisations is linked with Foucault’s description of the ‘orders of discourse’ that is then used to produce an organisational typology of three broad forms into which the range of organisations involved in the study are be placed. These are described as New Wave, Pragmat

In August 2018, the Georgetown University Center on Education and the Workforce (Georgetown Center) published a new report examining college students who work while enrolled. This report "explores the impact of hours worked, types of work, and completion rates by education level between low-income and higher-income working learners" and was written by Anthony P. Carnevale, Director of the Georgetown Center, and Nicole Smith, Chief Economist of the Georgetown Center. The researchers found that low-income students, who make up 43 percent of the working student body nationwide, tend to work more hours and have jobs unrelated to their studies and "as a result, are less likely than their higher-income peers to get good grades and attain bachelor's degrees or any credential at all." By contrast, higher-income working college students tend to work fewer hours and have better access to resume-building positions like internships while enrolled. Interested readers can download the full 40-page report or its 12-page executive summary as PDFs, and they can also view a PowerPoint presentation and a brief video summarizing the report.

Out-of-sample forecasting tests of DSGE models against time-series benchmarks such as an unrestricted VAR are increasingly used to check a) the specification b) the forecasting capacity of these models. We carry out a Monte Carlo experiment on a widely-used DSGE model to investigate the power of these tests. We find that in specification testing they have weak power relative to an in-sample indirect inference test; this implies that a DSGE model may be badly mis-specified and still improve forecasts from an unrestricted VAR. In testing forecasting capacity they also have quite weak power, particularly on the lefthand tail. By contrast a model that passes an indirect inference test of specification will almost definitely also improve on VAR forecasts.

European economic and monetary union is driven by politics, but the economic costs and benefits of Britain's membership can and should be assessed, argues Professor Patrick Minford in this careful and succinct analysis of the cases for and against Britain adopting the euro. The core argument in favour is the reduction of exchange-rate risk, but because the euro is a regional currency that has fluctuated considerably against the dollar, exchange-rate variability might not be less under the euro and could even increase. In any case, financial markets can diversify away such risks. Minford sees substantial costs of membership: increased variability of UK output, employment and prices in response to shocks; damaging harmonisation of tax rates, social support and regulation; and the possibility that British taxpayers will have to meet some of the costs of big projected state pension deficits in Germany, France and Italy. He concludes that EMU, 'as it is constituted and planned would be strongly against British interests to join'.

The thesis takes Mandeville's medical works at Leiden as a starting point. Translations of his first three works - all originally published in Latin - lay the foundation for a consideration of his approach to medicine, medical discourse and the contemporary seventeenth-century debates on Cartesian thought. From this basis, Mandeville's early English works are examined in detail. His fables are seen to develop the first stages of a complex theory of imitation which is closely related to his medical ideas on digestion. Mandeville elaborated this theory in three major works - The Virgin Unmask'd (1709), A Treatise of the Hypochondriack and Hysterick Passions (1711) and The Fable of the Bees (1714). Each of these works is examined in the context of contemporary texts and ideas. Taken as a trilogy, the works are shown to explore the problems of the individual in a rapidly changing society. The thesis argues that in The Virgin Unmask'd Mandeville considers the nature of seual identity and the various ways in which the new consumer society could operate to determine that identity. In A Treatise of the Hypochondriack and Hysterick Passions, it is shown that Mandeville continues his exploration of the effects of consumerism on the individual. In this text, however, he is concerned with consumption in both its literal and metaphorical dimensions as he fully develops the medical theories on digestion which he had begun to consider as a student in Leiden. Finally, Mandeville's first edition of The Fable of the Bees is examined in the light of his medical works and his interest in the nature of consumerism. Through the readings of each of these texts it is shown how Mandeville uses both the dialogue form and the `Remarks' of The Fable of the Bees to equip the reader with a set of interpretative tools. By using his chosen literary forms to question the notions of `knowledge' and `ignorance', he offers a perspective from which to `anatomize' the structures of power that were begin
