This thesis addresses spatial interpolation and temporal prediction using air pollution data by several space-time modelling approaches. Firstly, we implement the dynamic linear modelling (DLM) approach in spatial interpolation and find various potential problems with that approach. We develop software to implement our approach. Secondly, we implement a Bayesian spatial prediction (BSP) approach to model spatio-temporal ground-level ozone fields and compare the accuracy of that approach with that of the DLM. Thirdly, we develop a Bayesian version empirical orthogonal function (EOF) method to incorporate the uncertainties due to temporally varying spatial process, and the spatial variations at broad- and fine- scale. Finally, we extend the BSP into the DLM framework to develop a unified Bayesian spatio-temporal model for univariate and multivariate responses. The result generalizes a number of current approaches in this field. / Science, Faculty of / Statistics, Department of / Graduate

The specific instances of R.H.W. Shepherd and H.I.E. Dhlomo are used in this thesis to investigate some of the many factors that influence the formation of a colonial literature, such as politics, social structures and personal ideals. By isolating the Lovedale Mission Press ~s a "contact zone" - a·place where the cultures of the colonizer and the colonized come into direct contact with each other - it is possible to trace how the interaction between these cultures shaped the writing of a particular African writer, H.I.E. Dhlomo. This is done through an analysis of historical factors that shaped the policy of the Lovedale Mission Press in the twentieth century: the development of liberalism in South Africa, the·role of the missionary in African education, the function ofa liberal magazine such as The South African Outlook and the appointment of an ambitious missionary, R.I.W. Shepherd, to the position of Director of Publications. This necessarily included a study of Shepherd's vision of African literature. On the other hand, this study takes cognisance of the factors that shaped Herbert Dhlomo's vision of literature: the development of African nationalism, the entrenchment of segregation as a politial doctrine, and most importantly, his struggle to have his creative writing published by the Lovedale Press. It is shown how Shepherd's vision of what African literature should entail contrasted with Dhlomo's, and how, as a result, Dhlomo deliberately structured his critical writing as a response to Shepherd's Eurocentric approach to African literature.

The decades before the Scottish Reformation Parliament of 1560 witnessed the unprecedented use of a range of different media to disseminate the Protestant message and to shape beliefs and attitudes. By placing these works within their historical context, this thesis explores the ways in which various media – academic discourse, courtly entertainments, printed poetry, public performances, preaching and pedagogical tools – were employed by evangelical and Protestant reformers to persuade and/or educate different audiences within sixteenth-century Scottish society. The thematic approach examines not only how the reformist message was packaged, but how the movement itself and its persuasive agenda developed, revealing the ways in which it appealed to ever broader circles of Scottish society. In their efforts to bring about religious change, the reformers capitalised on a number of traditional media, while using different media to address different audiences. Hoping to initiate reform from within Church institutions, the reformers first addressed their appeals to the kingdom's educated elite. When their attempts at reasoned academic discourse met with resistance, they turned their attention to the monarch, James V, and the royal court. Reformers within the court utilised courtly entertainments intended to amuse the royal circle and to influence the young king to oversee the reformation of religion within his realm. When, following James's untimely death in 1542, the throne passed to his infant daughter, the reformers took advantage of the period of uncertainty that accompanied the minority. Through the relatively new technology of print, David Lindsay's poetry and English propaganda presented the reformist message to audiences beyond the kingdom's elite. Lindsay and other reformers also exploited the oral media of religious theatre in public spaces, while preaching was one of the most theologically significant, though under-researched, means of disseminating the reformist message. In addition to works intended to convert, the reformers also recognised the need for literature to edify the already converted. To this end, they produced pedagogical tools for use in individual and group devotions. Through the examination of these various media of persuasion, this study contributes to our understanding of the means by which reformed ideas were disseminated in Scotland, as well as the development of the reformist movement before 1560.
