Once a city of two million people, and the centre of US car manufacture, Detroit's fortunes have been in steady decline since the mid twentieth century, when the industry that built it began to downsize and relocate production away from the United States. Decades of disinvestment and racial division left a city with central neighbourhoods sparsely populated and crumbling, while resources and services were concentrated in wealthier suburbs. In recent years, the city's landscape has come to be emblematic of post-industrial decline, urban blight and civic abandonment. My research adopts a mixed-methods ethnographic approach to argue that this framing of the city is in fact a deeply ideological one, with constructions of Detroit as empty and chaotic serving to lay the groundwork for a large-scale project of re-colonisation, which draws simultaneously on discourses of greening and redemption. Narratives of abandonment and the re-emergence of urban 'nature' work together to reclaim the city in the interests of a mobile elite whose 'white flight', widely cited as the source of Detroit's problems, never flew much further than the suburbs. Drawing on news media, documentary film, television, photography, semi-structured interviews and extended periods of participant observation in Detroit between 2012 and 2014, I show how constructions of emptiness, a wilful fictionalisation of Detroit's recent history, narratives of greening and a pervasive investment in structures of white supremacy serve to create a Detroit in which wholesale gentrification may be put forward as a social good.

This thesis is an ethnographic study of an area in Manchester known as the 'Gay Village'. It explores the history and changes in the meaning of this term for the people who live and work in the Village, as well as for those who visit it for leisure. The Village was originally created by gay activists who emphasised being gay as the basis for having a separate gay community. However, since being incorporated into Manchester City Council's culture-led regeneration strategy the area now attracts large numbers of heterosexual male and female users. For many heterosexual Village users being gay attaches as much to 'things' that they feel able to engage with in the making of themselves, as much as what it attaches to persons through the way they define their sexuality. Within the Village previous assumptions about the authenticity of the categories 'gay' and 'straight' have been subjected to much debate. The aim of the thesis is therefore to subject current understandings of contemporary gay and straight sexuality to critical analysis and to explore how ideas about sexual identity may be changing in Britain in the first decade of the 21St century.
