The intra-Traveller debate on ‘Traveller ethnicity’ in the Republic of Ireland. A critical discourse analysis

This dissertation assesses from an under-explored angle the enduring contention over Travellers’ ethnic recognition in the Republic of Ireland, particularly over the last decade. The novelty of this study concerns not only its specific focus on and engagement with the debate on ‘Traveller ethnicity’ among Traveller activists. It also pertains to the examination of Travellers’ arguments for and against ethnicity in light of critical theorisations as well as insights from identity politics. Furthermore, the adoption of a Critical Discourse Analytical framework offers new perspectives to this controversy and its potential implications. Finally, this thesis’ relevance extends beyond the contention on ‘Traveller ethnicity’ in itself. It also draws attention to the complex dynamics of colonisation and appropriation between the global and the local. Particularly, it points to the interplay between international human rights discourses and the local ones, formulated by NGOs struggling for equality. In this way it sheds light on more general issues such as the dialectical potential of human rights discourses: the benefits and pitfalls of framing recognition claims in the legalistic terms of human rights. In this study it is argued that the contention on ‘Traveller ethnicity’ defies a simplistic polarisation between Irish Travellers and the Irish State since it has been simultaneously played out within the Travelling community. Specifically, this study explores how ‘Traveller ethnicity’ has been introduced, embraced, promoted and contested within Traveller politics to the point of becoming a hotly debated and divisive issue among Traveller activists and at the heart of the community itself. Putting Traveller activists centre-stage, their discourses for and against ‘Traveller ethnicity’ are examined and assessed against one another and their potential implications for Traveller politics, policies and identities are pointed out. Contending discourses are historically contextualised as the product of specific structural, material and discursive configurations of power and socio-economic relations within Irish society. Discourses for and against ‘Traveller ethnicity’ are assessed as being significant beyond the representational level. They are regarded as contributing to dialectically constitute Travellers’ ways of being, representing and acting. Furthermore these discourses are considered as sites and means of power struggles, whose stakes are not only words, but relate to issues of power and leadership within the Travelling community; adjudications over material resources; the adoption of certain policy approaches over others; and, finally, the consolidation of certain subject positions over others for Travellers to draw upon and relate to mainstream society. This study highlights an ongoing ideological struggle for the naturalisation of ‘Traveller ethnicity’ as a self-evident ‘fact’, which involves no active choice by Travellers themselves. Overall, ‘Traveller ethnicity’ appears to constitute an enduring source of dilemmas for the Travelling community. These revolve around the contradictory potential of ethnicity claims-making —both its perils and advantages— and its status as a potent political strategic resource that can both challenge and reinforce existing power relations, policies and identities.

People and place in the new frontier: an examination of Han and Uyghur ethnic identities

This thesis demonstrates how Han and Uyghur ethnic identities are constructed in urban Xinjiang, how they have evolved over time and how both identities gain their meaning largely from a process of interaction with the ‘other’. It shows that the boundaries that exist between Uyghur and Han hugely influence the identity content of both. Based on over 120 interviews carried out over 3 years, it brings a clear analytical framework and conceptual clarity to the questions of how ethnic identities are constructed and maintained in Xinjiang

New phosphorescence based probes and techniques for the analysis of cellular oxygen and respiration

Real time monitoring of oxygenation and respiration is on the cutting edge of bioanalysis, including studies of cell metabolism, bioenergetics, mitochondrial function and drug toxicity. This thesis presents the development and evaluation of new luminescent probes and techniques for intracellular O2 sensing and imaging. A new oxygen consumption rate (OCR) platform based on the commercial microfluidic perfusion channel μ-slides compatible with extra- and intracellular O2 sensitive probes, different cell lines and measurement conditions was developed. The design of semi-closed channels allowed cell treatments, multiplexing with other assays and two-fold higher sensitivity to compare with microtiter plate. We compared three common OCR platforms: hermetically sealed quartz cuvettes for absolute OCRs, partially sealed with mineral oil 96-WPs for relative OCRs, and open 96-WPs for local cell oxygenation. Both 96-WP platforms were calibrated against absolute OCR platform with MEF cell line, phosphorescent O2 probe MitoXpress-Intra and time-resolved fluorescence reader. Found correlations allow tracing of cell respiration over time in a high throughput format with the possibility of cell stimulation and of changing measurement conditions. A new multimodal intracellular O2 probe, based on the phosphorescent reporter dye PtTFPP, fluorescent FRET donor and two-photon antennae PFO and cationic nanoparticles RL-100 was described. This probe, called MM2, possesses high brightness, photo- and chemical stability, low toxicity, efficient cell staining and high-resolution intracellular O2 imaging with 2D and 3D cell cultures in intensity, ratiometric and lifetime-based modalities with luminescence readers and FLIM microscopes. Extended range of O2 sensitive probes was designed and studied in order to optimize their spectral characteristics and intracellular targeting, using different NPs materials, delivery vectors, ratiometric pairs and IR dyes. The presented improvements provide useful tool for high sensitive monitoring and imaging of intracellular O2 in different measurement formats with wide range of physiological applications.

Problems with drawing lines: Theo-geographies of the Catholic parish in Ireland

While people in Catholic parishes in Ireland appear keenly aware of parish boundaries, these understandings are more often oral than cartographic. There is no digital map of all of the Catholic parishes in Ireland. However, the institutional Catholic Church insists that no square kilometre can exist outside of a parish boundary. In this paper, I explain a process whereby the Catholic parishes of Ireland were produced digitally. I will outline some of the technical challenges of digitizing such boundaries. In making these maps, it is not only a question of drawing lines but mapping people’s understanding of their locality. Through an example of one part of the digitisation project, I want to talk about how verifying maps with local people often complicates something which may have at first sight seemed simple. The paper ends on a comparison with how other communities of interest are territorialised in Ireland and elsewhere to draw out some broader theoretical and theological issues of concern.
