This study is about refugee integration: how refugees become citizens, and more generally how outsiders become insiders. More specifically, it is about an appropriate conceptual framework for studying and understanding refugee integration processes. I propose that refugee integration be understood as local politics, and that, therefore, refugees and hosts negotiate their relationships with each other based on their respective interests and using a series of material and symbolic exchanges. While this conceptual approach to integration seems self- evident, this empirical, process-oriented, and spatially and temporally specific approach radically departs from the predominant normative assumptions in the policy and academic literature. The thesis sets out and develops how this simple framework, consistently applied, carries analytical correlates which stand in marked contrast to most analyses of refugee integration processes. My argument is supported empirically with a detailed case study of villages in a rural border area of South Africa where many (former) Mozambican refugees are settled since the 1980s. I spent four years (2002-2006) living and conducting field work in this area. The thesis by published (and publishable) works includes five articles covering different aspects of refugee integration as political negotiation. These include: 1) analysing the conceptual dangers and empirical fallacies of approaches to local integration which frame it as a ‘solution’ within the international refugee assistance and protection regime; 2) illustrating how common conceptual and methodological approaches to studying refugees tend to hide the presence of integrated refugees; 3) applying the political negotiation approach across time periods by comparing the integration processes of two ‘waves’ of Mozambicans fleeing conflict into South Africa in the mid-1800s and the 1980s; 4) showing how integration processes, including those related to legal status, often function according to very different logics than intended by national or international legal frameworks and policies targeting refugees; and 5) looking at processes of negotiated integration at the level of the village and how they are spatialised.

The research question that this thesis seeks to address is how contemporary liberal states, that are characterised by cultural diversity, should respond to cultural heritage. The argument of this thesis is that liberal states are fundamentally obliged to ensure that individuals have the greatest freedom possible to engage with their own cultural heritages. Cultural heritage and practices play a crucial role in the construction and maintenance of individual and group identity, and thus a response of non-intervention in cultural heritage provides the best means of respecting this significance. Although a government may not be sympathetic to certain ideas and ways of living, this does not give it a right to destroy or damage any cultural artifacts and objects, unless these objects or practices actively incite violence or harm to others, because doing so would necessarily violate the liberal proviso to abstain for interfering in conceptions of the good. Liberal states do not have an obligation to preserve a national heritage, nor do they have a duty to preserve a diversity of (minority) cultural heritages. However, contemporary nation-states – liberal and otherwise – will necessarily possess certain attributes of cultural heritage, such as a national flag, language, symbols etc., that are likely to reflect the experiences of a dominant, national group. While this acknowledgement entails a diversion from ideal liberal theory and poses problems for the cultural neutrality of the liberal state, I argue that it is in the liberal states’ interest to maintain some objects of cultural heritage as these have instrumental value in fostering an understanding of the shared political community and respect for liberal values. However, liberal governments are obliged to ensure that existing public heritage does not unduly discriminate against minority cultural groups; thus sustaining political neutrality. The liberal response that I have outlined thus attempts to sustain liberal values whilst remaining mindful of contextual issues such as power relations between and within groups, and the necessary constraints of contemporary statehood.

In contrast to orthodox presentations of 'long distance nationalism' as an abstract politics without accountability or responsibility by theorists like Benedict Anderson, I argue that it is essential in the case of conflict diasporas to conceptualize the nature of diaspora support for homeland insurgencies as a contingent product of lived experience, perception, culture and history. Based on qualitative, ethnographic fieldwork, including an analysis of in-depth personal narratives from within the London Tamil diaspora, I attempt to describe the (trans) formative effects of violence, loss and displacement. I contend that the resulting viewpoints and aspirations carry the imprint of the de-territorialised ‘imagining’ of relationships, belonging and moral community which define the content of long distance nationalism. Using inter-disciplinary ideas from a range of theorists including Arjun Appadurai, I focus on a ‘process of becoming’ by which a specific transnational consciousness is engendered. The idea that conflict diaspora identity is defined by a complex interplay between a contextual and subjective understanding of political discourse; as well as the intellectual, moral, psychological and existential experience of being in diaspora is developed and held up against the current literature. Rather than seeing such displaced communities through the prism of a society in conflict in a distant homeland, I argue that we should consider how conflict has produced a particular epistemology of diasporic space and identity. I conclude by arguing that diaspora identity has its roots not only in a distant homeland but also in the hearts, minds and imagination of diaspora Tamils, where the complex obligations of being human in a time of conflict, override that of being a citizen, physically emplaced within a particular territory. I contend that such a perspective is both essential and yet often overlooked when seeking to interrogate the content of long distance nationalism in the dominant literature.

Cognitive dysfunction is a core characteristic of schizophrenia, which can often persist when other symptoms, particularly positive symptoms, may be improved with drug treatment. The non-competitive NMDA receptor antagonist, phencyclidine (PCP), is a psychomotor stimulant drug that has been shown to induce symptoms characteristic of schizophrenia in humans and animals. The aim of these studies was to use the sub-chronic PCP model in rats to investigate cognitive dysfunction in behavioural tests which have been highlighted as relevance by the MATRICS initiative (MATRICS.ucla.edu). The main tests used were attentional set-shifting, operant reversal learning, and novel object recognition tasks. The pharmacology of antipsychotics was studied in the reversal learning task using receptor selective compounds. Following this, experiments were carried out using in vitro electrophysiology and in vivo microdialysis in an attempt to investigate the mechanisms underpinning the PCP-induced cognitive deficits. The attentional set-shifting task is a test of executive function, the extra-dimensional shift (EDS) phase relates to the ability to shift attention to a different stimulus dimension; this is impaired in patients with schizophrenia. The studies presented in chapter 2 showed that sub-chronic PCP administration impaired attentional set-shifting performance selectively in the EDS phase, a deficit which was significantly attenuated by sub-chronic administration of clozapine and risperidone, but not haloperidol. The effect of PCP was also shown to be more robust in female rats compared to males. A deficit in set-shifting ability was also observed in isolation reared rats. However, the deficits produced by PCP were more robust than the deficit produced by isolation rearing. The reversal learning task is another test of executive function. Chapter 3 reported that sub-chronic PCP administration impairs reversal learning ability in an operant task, as demonstrated by reduced percent correct responding in the reversal phase of the reversal learning task. It was found that a D1 agonist (SKF-38398), a 5-HT1A partial agonist (buspirone), a 5-HT2C antagonist (SB-243213A) and an agonist and positive allosteric modulator of the alpha 7 nACh receptor (PNU-282987 and PheTQS respectively) are able to reverse the sub-chronic PCP-induced deficit in reversal learning. Although many antipsychotics have affinity for muscarinic M1 and histamine H1 receptors, selective agents at these receptors were not able to improve the PCP-induced deficit. In chapter 4, the atypical antipsychotics, clozapine and risperidone, when given alone to naïve rats had no effect on reversal learning. Haloperidol when given to naïve rats impaired performance at the highest dose. Sub-chronic PCP was again found to impair reversal learning performance. Investigative experiments revealed that the 2 min time-out could be important as a cue. Following a double reversal, olanzapine-treated rats lost the ability to switch between the rules, whereas clozapine and risperidone-treated rats could perform the double reversal. Experiments with the extended (15 min) reversal phase could allow the investigation of the time-course effects of antipsychotics or selective compounds. The studies presented in chapter 5 found a reduction in gamma oscillations in the CA3 region of the hippocampus, following sub-chronic PCP treatment (2-5 weeks post treatment) that was paralleled by a deficit in parvalbumin immunoreactive (IR) cell density, at a similar time point (2 weeks post treatment). In contrast, a time-dependent increase in gamma oscillations was observed (6-8 weeks post treatment), at which point parvalbumin IR cell density was unchanged (8 weeks post treatment). Gamma oscillations were unchanged in the prefrontal cortex (PFC) following the PCP treatment regime. Locomotor activity tests were also carried out to ensure that the sub-chronic PCP treatment was successful. In-vivo microdialysis revealed that vehicle-treated rats show an increase in dopamine in the PFC which is selective for the retention trial of the novel object recognition task. PCP-treated rats were unable to distinguish between the novel and familiar objects and the increase in dopamine observed in vehicle rats was absent. As a control experiment it was also shown that sub-chronic PCP did not induce anxiety-like symptoms in the elevated plus maze and open field tests. These studies suggest that sub-chronic PCP induces cognitive deficits in behavioural tasks, and these deficits may be due to GABAergic mediated processes in the hippocampus and dopaminergic dysfunction in the PFC. These behavioural and neurochemical results are concurrent to findings observed in schizophrenia.

In my doctoral dissertation I explore the key role played by the eighteenth-century enlightened narrative of civilisation in the shaping of a Eurocentric/racist construction of the world. I do this by analysing how, in sources from the realms of moral philosophy and natural history, the intertwining discourses of luxury, sensibility, taste and climate that fuelled the narrative of civilisation created an understanding of human nature that made eighteenth-century scientific racism possible. The entire non-European world (the East, Africa and America) was presented as a space inhabited by unnatural bodies. Although Europe itself was not characterised as monolithic, (these writers saw a clear boundary between Northern and Southern Europe), the joint efforts of both moral philosophers and natural historians clearly distinguished Europe and the European body from the rest of the world. The Eurocentric/racist eighteenth-century construction of the world was so powerful in naturalising the European human and national prototype as a universal normative standard that it even found agents in other continents who were willing to argue that they too belonged to the European civilisation. Even those whom Europeans explicitly cast as inhabiting spaces unfit for the unfolding of civilisation, and thus as spaces where the European human prototype inevitably degenerated, might insist that they too conformed to the European human and national prototype. The idea of Europe as the centre of the world would not have triumphed had agents outside Europe not participated in its making. This was the case of the New Granadan Creoles, the founding fathers of the Colombian nation, who far from questioning the Eurocentric racist/lens of civilisation whereby European savants had dismissed the non-European world as inferior, instead reinforced it.

The objective of this study is to shed more light on the electrochemical interface of HTPEM fuel cell. More specifically, to understand and improve the electrochemical interface of both the anodic and cathodic electrode in HTPEM fuel cells, as well as optimize the catalyst layer structure for operation under various challenging conditions. For that reason the effect of the PA amount in the catalyst layer and the effect of the catalyst’s substrate on the fuel cell’s performance were investigated. Initially the poisoning effect of PA on the anodic electrode was investigated. The PA amount was altered in the anodic catalyst layer and its effect on the ECSA and the anode’s performance were evaluated. It was observed that the reversible performance loss of the anodic electrode was a function of the PA amount in the catalyst layer. More specifically, under low PA loading (<3 gPA/gPt) on the anodic electrode, < 10% of the Pt active surface is electrochemically active under fuel cell operating conditions. This was attributed to the blockage of the Pt surface by pyrophosphoric acid or poly-phosphates, H2 reduced polyphosphoric acid species and the shrinkage of the interface due to the displacement of the H3PO4 by the adsorbed H2 species. High PA loadings reduced the poisoning effect of these reduced PA species ( >3 gPA/gPt). It was found that the controlled and increased PA content within the catalytic layer can result even up to the tenfold decrease in the Pt loading when the anode operates under H2 rich conditions. In order to increase the fuel cell performance and increase the three phase boundary, a newly synthesized electrocatalyst was evaluated, and compared to the commercial 30wt%Pt/C. The new catalyst is based on pyridine functionalized carbon nanotubes ,30wt%Pt/oxMWCNT-Py. Pyridine groups are known to interact with PA and thus it is expected to increase the TPB and lower the Pt loading. CL employing the new catalyst were formulated and tested at the anodes. It was found that the presence of pyridine groups homogeneously distributed PA in the catalyst layer, resulting in high ECSA values, 40m2/gPt. As a result the MEA employing 30wt% Pt oxMWCNT-Py showed the same performance as the 30%Pt/C (having 1.3mgPt/cm2), for Pt loading loadings as low as 0.2mgPt/cm2. The performance of the anodic electrode was also found to be largely depended on the PA amount imbedded in the CL, when low Pt loading were used. The latter was an effect of the shrinkage of the ECSA as a result of the formation of PA poisoning species, as also mentioned in the previous paragraph. Since 30wt% Pt/oxMWCNT-Py exhibited very promising results and high ECSA values, its performance under harsh synthetic reformate gas was also evaluated. The synthetic reformate gas that was used comprised of 50.7kPa of H2, 2 kPa of CO and 33.5kPa of H2O balanced with Ar. It was found that the 30wt%Pt/oxMWCNT-Py electrocatalyst are ideal candidates for operation under those harsh reformates conditions, as they exhibited smaller voltage losses and higher stability under these conditions. The interaction of pyridine groups with phosphoric acid not only promotes its uniform distribution on the CL but also stabilizes the EI under high partial pressure of water. Additionally, the use of pyridine functionalized MWCNT based electrocatalyst gives the opportunity of lowering the Pt loading in the electrodes without sacrificing the overall cell’s performance under reformate conditions. The observed voltage loss under synthetic reformate gas rich in CO and steam was found to be a multi-step process and a function of the hydrophobicity of catalyst substrate, the PA loading in the CL as well as the water and CO molar fraction in the reformate gas. In order to optimize the cathodic catalyst layer, CL were formulated using the newly synthesized electrocatalyst (30wt%Pt/oxMWCNT-Py) and compared to the commercial 30wt%Pt/C. A full parametric analysis with respect to catalyst type, PA loading and Pt loading was conducted. It was found that the presence of pyridine groups homogeneously distributes PA in the catalyst layer minimizing the blockage of the pores of the catalyst layer and increase the three phase boundary. As a result the MEA employing 30wt% Pt oxMWCNT-Py showed the same performance as the 30%Pt/C for half the Pt loading. Despite the hard operating conditions the Pt particles attached to the ox.MWCNT-Py substrate exhibit the same stability as the commercial catalyst and the pyridine groups were found to be stable, at least for short term operation at the cathodic and anodic electrode. Also optimization of the ECSA evaluation procedure at the cathodic electrode, using CO as a probe molecule, without damaging the Pt distribution was found. It is clear that the use of this newly synthesized electrocatalyts 30wt%Pt/oxMWCNT-Py , at both electrodes, has major advantages as it increase the catalyst utilization and there is no need to use a polymer-binder inside the catalytic layer. Thus avoiding problems of inhomogeneous binder distribution and/or electronic insulation of catalyst nanoparticles. Using 30wt%Pt/oxMWCNT-Py electrocatalyst opens the possibility of significant reduction of the amount of Pt on both electrodes, under various operation conditions, without sacrificing the performance and stability of the fuel cell. / Στο πλαίσιο της παρούσας διδακτορικής διατριβής έγινε σύνθεση ενός νέου βελτιωμένου ηλεκτροκαταλύτη Pt για χρήση σε κελιά καυσίμου πολυμερικής μεμβράνης υψηλών θερμοκρασιών (HTPEM), με σκοπό την αύξηση της ηλεκτροχημικά ενεργού επιφάνειας τόσο του ανοδικού όσο του καθοδικού ηλεκτροδίου. Ο καταλύτης αυτός αποτελείται από 30 % κ.β. Pt σε φορέα τροποποιημένους πολυ-φλοιϊκούς νανοσωλήνες άνθρακα (MWCNT). Οι νανοσωλήνες άνθρακα τροποποιήθηκαν σταδιακά, σε ένα πρώτο βήμα με ομάδες οξυγόνου (ox.MWCNT) και στη συνέχεια με ομάδες πυριδίνης (ox.MWCNT-Py) που προσαρτήθηκαν μέσω ομοιοπολικών δεσμών στο εξωτερικό τοίχωμά τους, ώστε να επιτευχθεί ομοιόμορφη κατανομή τους στο καταλυτικό στρώμα. Επειδή οι ομάδες πυριδίνης (Py) δεσμεύουν το φωσφορικό οξύ, το οποίο χρησιμοποιείται ως ιοντικός αγωγός, δημιουργείται ένας ιοντικά αγώγιμος δρόμος κατά μήκος του καταλυτικού στρώματος, με συνακόλουθη αύξηση της ηλεκτροχημικά ενεργού επιφάνειας, η οποία επέτρεψε τη σημαντική μείωση της ποσότητας Pt στα ηλεκτρόδια, χωρίς μείωση της απόδοσης και σταθερότητας του κελιού καυσίμου. Πλεονέκτημα αυτής της προσέγγισης για αύξηση της απόδοσης του ηλεκτροκαταλύτη Pt είναι το ότι αποφεύγεται η χρήση ενός ιονομερούς στο εσωτερικό του καταλυτικού στρώματος και τα προβλήματα που σχετίζονται με την ανομοιογενή κατανομή του. Εξετάστηκαν επίσης η επίδραση στην απόδοση του ανοδικού ηλεκτροδίου της παρουσίας CO και υψηλής μερικής πίεσης υδρατμού στην τροφοδοσία της ανόδου, στη περίπτωση χρήσης αερίου αναμόρφωσης ως καυσίμου. Για διερεύνηση του μηχανισμού ανάπτυξης υπέρτασης (ενεργειακής απώλειας σε όρους δυναμικού) στη περίπτωση αυτή και βελτιστοποίηση της λειτουργίας του κελιού καυσίμου, παρασκευάστηκαν ηλεκτρόδια με χρήση τριών διαφορετικών καταλυτών Pt, συγκεκριμένα των καταλυτών 30% κ.β. Pt/C, 30% κ.β. /oxMWCNT και 30wt%Pt/oxMWCNT-Py. Τα ηλεκτρόδια αυτά διέφεραν επίσης όσον αφορά στη ποσότητα καταλύτη ανά μονάδα επιφάνειας ηλεκτροδίου και στη ποσότητα φωσφορικού οξέος (PA) στο καταλυτικό στρώμα ανά μονάδα μάζας Pt (0.5 gPA/gPt και 2 gPA/gPt). Η ανάπτυξη υπέρτασης στις αναφερθείσες συνθήκες λειτουργίας αποδόθηκε σε ένα μηχανισμό πολλών σταδίων, ο οποίος βασίζεται στη μείωση της ηλεκτροχημικά ενεργού επιφάνειας λόγω της εκτόπισης του φωσφορικού οξέος από την ηλεκτροχημική διεπιφάνεια. Παρότι το φωσφορικό οξύ αποτελεί ιδανικό αγωγό ιόντων για τα κελιά καυσίμου υψηλών θερμοκρασιών τύπου PEM, παρουσιάζει διάφορους περιορισμούς, όπως το φαινόμενο δηλητηρίασης του ανοδικού ηλεκτροδίου εξαιτίας του, το οποίο επίσης μελετήθηκε στη διατριβή αυτή. Διαπιστώθηκε ότι η αναστρέψιμη απώλεια της απόδοσης του ανοδικού ηλεκτροδίου ήταν συνάρτηση της ποσότητας του H3PO4 στο καταλυτικό στρώμα.

This study investigates the interplay of linguistic practices, linguistic representations, language ideologies and social inclusion between students in three related research sites in south west Wales;a designated English medium school,a designated Bilingual school and a Youth Club,as a point of contact between students from both schools. It identifies how students experience and interpret the language ideological content of their education. The following questions underpin the current research: 1. How are the institutional arrangements within this community(or locality)understood by the students? Do school students see themselves operating within language ideological structures?!Do students resist or affirm school based ideologies and school based practice? 2. How do students understand, interpret and live out what language policy and planning documents in Wales refer to as ‘true bilingualism’? Is ‘choice’ experienced as such at institutional, individual and community levels? 3. Is the Welsh language accounted to be an obstacle to social integration for young people within the ‘community’ and into the school environment, or a positive resource? Ethnographic research as been carried out in both schools and at the Youth Club,with three principle methods characterising this research; ethnographic observational fieldwork, ethnographic chats, and audio recordings of spontaneous interaction. vi This study sets out to investigate how the young people at two contrasting (and ideologically polarised) secondary schools in an ‘community’ traditionally thought of as a heartland area understand and orient to the language ideological content of their education. In the school based data language choice results in boundaries being put up around language and language users, both inter school and intra school, with students forming language hierarchies, positioning themselves and others as more or less Welsh, English or bilingual, ‘better’ or ‘worse’ at speaking Welsh and/or English, and more or less authentically Welsh. Schools serve to reinforce and reproduce social divisions, leading to issues of social exclusion. Contrastingly,the Youth Club data highlights that,when freed from the ideological constraints of the school, the young people reflect, sometimes critically, on their school based practice and school based ideologies. This study adds to our knowledge about Welsh medium/bilingual education in Wales; it helps us better understand ‘multilingual’Wales.

This thesis examined the early labour market experiences of graduates from different class backgrounds at three differentially ranked universities. It finds that outcomes are more than the sum of credentials and hard work. Access to social, economic and non-academic forms of cultural capital is found to be important and graduates from middle class backgrounds are more likely than graduates from working class backgrounds to access the forms of capital recognised by the graduate labour market. This leads to observable differences in graduate labour market outcomes. However, the complex relationship between higher education and the graduate labour market means that class differences are not simply reproduced. In the first instance, patterns in graduate labour market outcomes are a product of the academic requirements demanded by certain occupations. These academic barriers are tangible and affect all graduates regardless of background. Graduates with more prestigious credentials are more likely to access professional or managerial occupations and are more likely to find traditional graduate employment: the proportion of middle class graduates employed in professional or managerial occupations was 100% at the Elite University, 79% at the Russell Group University and 69% at the Post-1992 University. This compares with figures of 100%, 56% and 31%, respectively, for working class graduates. However, labour market success is also predicated upon exhibiting the ‘right’ combination of competencies and experiences, privileging middle class graduates. Middle class graduates have greater access to economic capital, are able to leverage their social networks to augment their employability, and are more likely to exhibit ways of being and doing associated with professional and managerial competence. As such, intra-university comparisons find that middle class graduates are more likely to access graduate employment (79% of Russell Group University middle class graduates were in graduate employment compared to 22% of working class graduates) and work in professional or managerial occupations (see figures above). These observations can be attributed to significant differences in economic, social and cultural capital. However, such comparisons conceal subtle in-group differences. This thesis identified distinct class fractions within both the middle and working class groups. An interesting distinction within the middle classes was that between middle class graduates with parents employed in the public/third sectors and those with parents employed in the private sector. For instance, 80% of graduates in the public sector had one or more parents employed by the public sector and almost 60% had both parents employed by the public sector, which constituted all of those with both parents employed by the public sector. All of the graduates in the private sector had at least one parent employed by the sector and 74% had both parents employed by the sector, constituting 85% of graduates with both parents employed in the private sector. The same pattern did not emerge for working class graduates. The sector of parental employment is significant because it reflects systematic differences in social and political orientation, which for graduates give rise to discernible differences in their inherited labour market orientation, social networks and cultural capital. The graduate labour market outcomes of working class graduates are acutely tied to the institutions they attend and their experiences therein. Unlike many middle class graduates, working class graduates do not inherit forms of social and cultural capital that can be easily realised in the graduate labour market. As such, differences between working class fractions can be traced to differences in educational achievement and trajectory. Through the acculturation of middle class behaviours and alignment of practices, working class graduates benefit from the institutional proximity to middle class peers and become caught in their ‘slip stream’. The benefits are clear to see: 65% of elite trajectory graduates were in traditional graduate employment and 94% were in professional or managerial occupations. For modal trajectory graduates mediocre credentials and low levels of inherited social and cultural capital are compounded by socially segregated institutional experiences. Consequently, they were found in the least competitive regions of the graduate labour market, typically in non-graduate employment and in occupations that did not require a degree-level education. These findings add to our understanding of how class background, higher education and the graduate labour market interact. They raise some important questions for the academic field but also for public policy, particularly around the role of higher education in promoting social mobility and its relationship with the (graduate) labour market.

This thesis examines how discourses are utilised by media and political elites to construct, propagate, and alter national and ethnic identities. It uses Latvia as a case study, focusing on the construction of ‘Russian-speaking’ identity from the late Soviet period to the present. A central aim of this research is to study how discursive constructions of identity are created, and to what extent media and politicians are able to influence such constructions. In order to meaningfully assess the extent of multiple influences over discursive production and consumption this research employs a triangulated approach, using data from focus groups, elite interviews with Latvian politicians, survey data, and discourse analysis of the Latvian press. This has allowed for a fuller examination and assessment of top-down and bottom-up influences and pressures on identity creation and how these are interrelated. Previously conducted research on ethnopolitical identities in Latvia has revealed how collective memories, interpretations of the Soviet past, post-Soviet state-building policies, and issues surrounding language usage are all heavily politicised and used to demarcate the boundaries between the ‘core nation’ (Latvians) on the one hand, and ‘Russian-speakers’ on the other. Accordingly, this research explores how the constructions of these positions are negotiated, propagated, intensified, or mitigated through discursive practices, as manifested in media, political, or personal discourses. This research is concerned with the temporally contingent nature of discourses and as such, considers multiple eras, rather than a single de-contextualised and static time period, to investigate how discourses have evolved in the Latvian context. By comparing discursive productions from the late Soviet period with those of the present, it has been possible to examine how certain discursive positions have become meaningfully embedded within popularly conceived notions of identity. It has also facilitated a study of discursive strategies by people who attempt to represent Russian-speakers in the media and political spaces. This research argues that discourses are firmly rooted in the past, even if their contemporary form differs greatly from that of the past.

Prehistoric Sardinia is best known for its Bronze Age Nuragic culture which lasted from the mid-2nd millennium until the early 1st millennium. The Iron Age and later prehistory of the island are often subsumed into discourses that emphasise the colonising Phoenicians (8th-6th centuries BC) and Carthaginians (6th-2nd centuries BC). In the north of the island the local communities, being neither part of the Bronze Age Nuragic culture nor of the colonized world of the south, are seen in relation to foreign communities rather than from local perspectives. This thesis uses postcolonial theoretical frameworks of island identity, consumption and materiality to examine the local/foreign interactions that take place in north Sardinia in the period between 900 – 200 BC. The main focus is to set the interrelationships between the local Sardinian communities and the Phoenician, Etruscan, Greek and Carthaginian traders and settlers who frequented the shores in a context that emphasises local and indigenous agency. At the same time this topic provides an opportunity to re-examine the scholarship that has led to north Sardinia being overlooked. This thesis covers a long time period and the project is divided geographically between three different zones of north Sardinia (the north-west, the central-east and the Olbia area) and chronologically between the 9th- 7th centuries, the 7th – 5th centuries and the 4th-2nd centuries BC. The data set includes the archaeological material from 51 north Sardinian sites that contain evidence of local/foreign interactions during these periods. Using this data a few well excavated sites are studied in greater detail to examine and question the models of acculturation and resistance that form the traditional perspectives of scholars working in the north. For example, the presence or lack of foreign material culture on indigenous sites has often been understood from the perspective that desire for foreign goods was natural. This approach overemphasises the role that foreign communities had in contact situations and at the same time underemphasises the agency and choices of the local inhabitants. Indeed an examination of the data shows how local practices continued and that the foreign presence had a limited impact. One of my aims in this thesis is to avoid a dualistic position which sets the local communities against foreign ones; in fact local/foreign interactions can result in the creation of ‘hybrid’ products, practices and communities and I explore how far we can see the hybridization of north Sardinian communities in the different phases of the 1st millennium through the material culture that informed their actions. A second aim is to explore what types of changes took place in north Sardinian identities through the types of objects they consumed. Some of the larger Iron Age sites were sanctuaries and thus I examine how far local communities used ritual as a way of mediating the exchanges between them and foreign people through their selection of the material culture. Thirdly, this thesis approaches the social identities of the Sardinians using a bottom-up approach to the interactions. This allows me to compare the different ways in which local communities experienced foreign contacts and culture over a broad period and the evidence illuminates the variety of ways that island identities were developed in the various regions of north Sardinia.
