The Union, The Nation, and the Talking Crow: The ideology and tactics of the Independent ICU in East London

African Studies Seminar series. Paper presented March,1985In January 1930 a meeting was held at Headman Koliwe's location in Kentani district, Transkei. It was addressed by Elias Mabodla (or Agitator No. 53 as he was identified in a police report) who had come "to preach ICU amongst you people". He recounted how nine trade union leaders had been arrested in East London where they had called a strike. Their plight evoked strong sympathy in Kentani, especially as one of those arrested was a local man, Dorrington Mqayi. Headman Nkonki summed up the mood of the meeting: "It is for us to see into this matter as our blood is amongst those people in the gaol at East London." Fifty years later, during our research on rural popular movements we encountered Mqayi in his identity as an ICU "agitator" in Kentani. We then retraced his footsteps. In an archival echo of his journeys between the Transkei and the harbour city, we moved from the boxes holding the records of the Kentani magistracy to those of the East London Town Clerk. We had no way of knowing whether Mqayi would resurface in the East London documents, but began our search for him in speculative optimism. We did meet Mqayi again - but not him alone. Mqayi in East London was not the leading actor that he might have been on the smaller stage of Kentani; rather, he had a modest speaking part in a vibrant urban drama - a drama recorded in the vivid and detailed police records* of ICU activity in the Town Clerk's files

Opening Our Eyes : How film contributes to the culture of the UK

Opening our eyes looks at how films are consumed and the factors which affect people’s viewing choices. It also covers the relationships audiences report between film and other activities. It goes on to explore the sorts of effects which film has upon people, their sense of identity and relationship with the world. Finally it looks at the various effects which individual films have had on those surveyed and reaches a number of conclusions.Final Published versio

Ciliate Endosymbiont Imaging Methodology

Ciliates, a phylum of diverse microbial eukaryotes, are found in a wide range of environments, including anoxia. Anaerobic ciliates host intracellular methanogenic archaea – a unique type of symbiosis. Despite their importance, anaerobic ciliates and their symbiotic relationships remain understudied. Included in this is the ability to image and quantify the intracellular methanogenic symbionts in a precise, timely and replicable procedure. This project aimed to improve the current fluorescence microscopy methodology used for endosymbiont quantification. The proposed method is intended for use with the Opera Phenix, a high throughput spinning disk confocal microscope which can count large amounts of individual cells automatically. Cells obtained from anaerobic cell cultures were fixed in paraformaldehyde, washed, and filtered before imaging. The findings of the study indicate that the method developed has potential. A challenge that remains is removing fine debris from the sample that interfere with automatic cell counting, while ensuring high ciliate concentrations that can be quantified. Once this challenge is addressed, the method developed could aid in gaining new insights into the complex relationship between ciliates and their endosymbionts

Production, Labour Migrancy and the Chieftancy: Aspects of the Political Economy of Pondoland, ca. 1860-1930.

This thesis is a contribution towards the study of the transformation of African society in South Africa under the impact of colonisation and capitalist development. It is a case study of political and economic change in one African chiefdom, the Mpondo, before and after the society was annexed by the Cape Colony in 1894. In the first chapter, an attempt is made to analyse the nature of the economy of the chiefdom prior to colonial rule, to discuss the relationship between chiefs and people, and to assess the effects of the penetration of colonial traders into the area. The second chapter, dealing with the response of the Mpondo chiefs to economic change, argues that the political conflict between the chiefs and colonial powers in the late nineteenth century must be located in the struggle for control over trade. Responses to Rinderpest (1897), the opening of colonial markets for Mpondo grain and attempts to mobilise a migrant labour force from Pondoland are analysed in chapter three. It is sug-gested that the simultaneous increase in grain production and migrancy can only be explained if the particular form of early migrancy and the structure of Mpondo homesteads is understood. Chapter four illustrates the effects of state intervention in Pondoland after Union (1910). While the Mpondo were blocked from markets for much of their produce and more deeply incorporated into the capitalist economy as migrant labourers, changes in patterns of cropping and family structure enabled output to be maintained. In chapter five, it is argued that the Cape and Union governments, after attempting, initially, to destroy the chieftaincy, allowed the chiefs some leeway in order to maintain control in Pondoland. The survival of chiefly authority, especially insofar as it included control over the distribution of land, had important implications for the nature of production and stratification in the area. Rural differentiation, emerging rural class divisions, and conflicts and alliances in rural politics are discussed in chapter six
