LaAlO3-based topcoats for novel thermal barrier coatings deposited by means solution precursor thermal spraying

In this study we present the development of LaAlO3 coatings for TBC applications, by means of SPTS. LaAlO3 precursor solutions have been synthesized followed the in situ polymerization with citric acid [16-17]. The details of the solution synthesis, and deposition method, along with characterization of the deposits by means of Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD) analysis, and microhardness measurements is reported. The effect of critical plasma spray deposition parameters on the resulting microstructural characteristics and phase composition of the developed coatings is discussed

Development of electric resistance sintering process for the fabrication of hard metals: Processing, microstructure and mechanical properties

This work presents the development of the Electrical Resistance Sintering (ERS) process for the fabrication of hard metals. The compositions of the materials produced were WC with 6 and 10 wt% of Co. In addition to the specific characteristics of the technology, the characterization of the produced parts is presented and compared to materials obtained by conventional processes. The parts produced by ERS present densities comparable to the ones obtained by conventional methods. The microstructural comparison shows a considerable grain size reduction in the ERS materials which consequently brings a hardness increase. ERS materials show similar fracture toughness to conventional ones. The very fast sintering allows performing the process without any protective atmosphere, therefore making this process very attractive for the production of materials that need to be sintered under non-oxidising environments. The total duration of the cycle, including heating, holding time and cooling is few seconds. Finally, some considerations about the scale up and possible industrialization of the technology are explained.This work is financially supported by the Seventh Framework Program of the Commission of the European Communities under project EFFIPRO contract no.

Everyday cosmopolitanism in representations of Europe among young Romanians in Britain

The paper presents an analysis of everyday cosmopolitanism in constructions of Europe among young Romanian nationals living in Britain. Adopting a social representations approach, cosmopolitanism is understood as a cultural symbolic resource that is part of everyday knowledge. Through a discursively-oriented analysis of focus group data, we explore the ways in which notions of cosmopolitanism intersect with images of Europeanness in the accounts of participants. We show that, for our participants, representations of Europe are anchored in an Orientalist schema of West-vs.-East, whereby the West is seen as epitomising European values of modernity and progress, while the East is seen as backward and traditional. Our findings further show that representations of cosmopolitanism reinforce this East/West dichotomy, within a discourse of ‘Occidental cosmopolitanism’. The paper concludes with a critical discussion of the diverse and complex ideological foundations of these constructions of European cosmopolitanism and their implications

Social representations and the politics of participation

Recent work has called for the integration of different perspectives into the field of political psychology (Haste, 2012). This chapter suggests that one possible direction that such efforts can take is studying the role that social representations theory (SRT) can play in understanding political participation and social change. Social representations are systems of common-sense knowledge and social practice; they provide the lens through which to view and create social and political realities, mediate people's relations with these sociopolitical worlds and defend cultural and political identities. Social representations are therefore key for conceptualising participation as the activity that locates individuals and social groups in their sociopolitical world. Political participation is generally seen as conditional to membership of sociopolitical groups and therefore is often linked to citizenship. To be a citizen of a society or a member of any social group one has to participate as such. Often political participation is defined as the ability to communicate one's views to the political elite or to the political establishment (Uhlaner, 2001), or simply explicit involvement in politics and electoral processes (Milbrath, 1965). However, following scholars on ideology (Eagleton, 1991; Thompson, 1990) and social knowledge (Jovchelovitch, 2007), we extend our understanding of political participation to all social relations and also develop a more agentic model where individuals and groups construct, develop and resist their own views, ideas and beliefs. We thus adopt a broader approach to participation in comparison to other political-psychological approaches, such as personality approaches (e.g. Mondak and Halperin, 2008) and cognitive approaches or, more recently, neuropsychological approaches (Hatemi and McDermott, 2012). We move away from a focus on the individual's political behaviour and its antecedents and outline an approach that focuses on the interaction between psychological and political phenomena (Deutsch and Kinnvall, 2002) through examining the politics of social knowledge

Adult women and ADHD: on the temporal dimensions of ADHD identities

This paper uses conceptual resources drawn psychosocial process thinking (Stenner, 2017, Brown and Reavey, 2015, Brown and Stenner, 2009) and from G.H. Mead in particular, to contribute to an emerging body of work on the experiences of adult women with ADHD (Singh, 2002, Waite and Ivey, 2009, Quinn and Madhoo, 2014, Horton-Salway and Davies, 2018). It has a particular focus on how ADHD features in the construction of women’s identities and life-stories and it draws upon findings from a qualitative investigation of adult women diagnosed or self-diagnosed with Attention Deficit Hyperactivity Disorder (ADHD). A theoretically informed ‘thematic decomposition’ of 16 depth interviews reveals how complex processes of identity transformation are mediated by the social category of ADHD. Through this process, pasts are reconstructed from the perspective of an ‘emergent’ identity that offers participants the potential for a more enabling and positive future

Exploring the Demands of Assimilation among White Ethnic Majorities in Western Europe

This article was published in the journal, Journal of Ethnic and Migration Studies [© Routledge (Taylor & Francis)] and the definitive version is available at: http://dx.doi.org/10.1080/1369183X.2012.640015Since the mid-1990s, assimilation has gradually regained momentum as both a normative and an analytical concept for understanding the ways in which migrants are incorporated into societies at large. Although scholars have investigated various dimensions of this process, they have tended to privilege the experience of migrants themselves. Comparatively little attention has been dedicated to the perspective of the dominant groups, particularly in relation to what ethnic majority people demand that migrants do in order to be accepted. This article explores these demands of assimilation through qualitative data collected among white local elites in four regional case-studies in Western Europe. The analysis reveals a different picture from the one usually portrayed by 'new assimilation theory'. Accordingly, I suggest rethinking assimilation in ways which incorporate more fully the plurality of demands put forward by dominant ethnic groups. © 2012 Copyright Taylor and Francis Group, LLC

International migration and the rise of the ‘civil’ nation

This is an Accepted Manuscript of an article published in Journal of Ethnic and Migration Studies on 2 March 2016, available online: http://www.tandfonline.com/10.1080/1369183X.2016.1155980Scholars largely agree that immigration policies in Western Europe have switched to a liberal, civic model. Labelled as ‘civic turn’, ‘civic integration’ or ‘liberal convergence’, this model is not identically applied across countries, since national institutions, traditions and identifications still matter. Even so, the main focus is on processes which allow or prevent migrants to be incorporated into nations usually taken for granted in their meanings. Moving from policies to discourses, this article aims to interrogate what kind of nation is behind these policies as a way to further scrutinise the ‘civic turn’. Exploring how the term ‘civility’ and its adjectivisations are discursively deployed in Italian parliamentary debates on immigration and integration issues, the article points to two opposite narratives of nation. While one mobilises civility in order to rewrite the nation in terms of a common, inclusive, civic ‘we’, the other uses civility to reaffirm the conflation between national identity and the identity of the ethno-cultural majority. These findings suggest the importance of exploring the ‘civic turn’ not only across countries, but also across political parties within the same country to capture the ways in which a liberal, civic convergence in political discourses might hide divergent national boundary mechanisms

Comparing children's care work across majority and minority worlds

Comparative qualitative methodologies that investigate children's lives in sharply contrasting socio-economic, political and welfare contexts are relatively unusual. Yet within an increasingly interdependent globalised world, comparative research and dialogue across binaries seems ever more important. In this chapter, we critically reflect on global conceptualisations of young caregiving and discuss the methodological and ethical challenges that arose in our comparative study of children caring for a parent/relative living with HIV in Tanzania and the UK. We discuss the potential problems and benefits of using the term "young carer" and suggest that levels of support and recognition of children's caring roles in particular countries do not follow a simple Majority/Minority world binary, but rather reveal a more complex picture. We argue that developing global perspectives that work across geographical, linguistic and disciplinary boundaries can facilitate greater understanding of the commonalities and diversities of children's caring lives globally

Empowerment of intergroup harmony and equity

The impact of empowerment interventions is often short-lived because they are not anchored in changes in the wider social and structural context. This chapter draws its inspiration from social representation theory and social identity theory. Several theoretical propositions are derived from these theories that bear on the effectiveness of empowerment interventions. Drawing on field experiences with Roma communities and young unemployed people in Hungary and Italy, we demonstrate how a focus on intergroup interactions, between minority and majority group members, is central to the empowerment process. In addition, we address the role of power and the means by which power can be dissembled and more equitably shared. Finally, we discuss the importance of placing contextual factors at the center of our analysis and enacting changes in context in order to arrive at empowerment interventions that produce sustainable changes in intergroup harmony and equity
