A Symbolic-Numeric Software Package for the Computation of the GCD of Several Polynomials

This survey is intended to present a package of algorithms for the computation of exact or approximate GCDs of sets of several polynomials and the evaluation of the quality of the produced solutions. These algorithms are designed to operate in symbolic-numeric computational environments. The key of their effectiveness is the appropriate selection of the right type of operations (symbolic or numeric) for the individual parts of the algorithms. Symbolic processing is used to improve on the conditioning of the input data and handle an ill-conditioned sub-problem and numeric tools are used in accelerating certain parts of an algorithm. A sort description of the basic algorithms of the package is presented by using the symbolic-numeric programming code of Maple

The Euclidean Division as an Iterative ERES-based Process

Considering the Euclidean division of two real polynomials, we present an iterative process based on the ERES method to compute the remainder of the division and we represent it using a simple matrix form

East European migrant women in Greece: intergenerational cultural knowledge transfer and adaptation in a context of crisis

This paper draws on a larger oral history project entitled ‘Gendered Histories of Resilience and Resistance: Eastern European Women’s Narratives of Mobility and Survival’, a narrative ethnography of Albanian, Bulgarian, Romanian, and Polish immigrant women living in Greece. The paper explores intergenerational cultural knowledge transfer and adaptation in a context of crisis with an analysis contextualised within the current crisis in Greece. We consider here the degree of uncertainty and the emotional challenges and constraints, but consider also the creativity and agency that participants display. Following on from that we aim to unravel the impact of ‘family and cultural values’ on migrants’ everyday lives in the diaspora

Diasporic youth identities of uncertainty and hope: second-generation Albanian experiences of transnational mobility in an era of economic crisis in Greece

This paper explores various dimensions of ‘gender’ and ‘mobility’ among immigrant youth from a transnational perspective in an era of economic crisis. The extent and parameters of continuity, contestation and change in migrant youth identities are analysed and we suggest that neither gender nor identity are stable categories but are embedded in sociocultural particularities both in the country of residence (Greece) but also in the country of origin (Albania). Through in-depth interviews with 52 participants, all second-generation Albanian immigrants in Greece born to two Albanian parents, the paper addresses youth identification in relation to gendered representations of belonging. The narrative accounts that we have selected and analysed reflect the emotional challenges, constraints and creativity of Albanian youth

Theorizing black (African) transnational masculinities

Just as masculinity is crucial in the construction of nationhood, masculinity is also significant in the making and unmaking of transnational communities. This article focuses on how black African men negotiate and perform respectable masculinity in transnational settings such as the workplace, community and family. Moving away from conceptualizations of black transnational forms of masculinities as in perpetual crisis and drawing on qualitative data collected from members of the new African diaspora in London, the article explores the diverse ways notions of masculinity and gender identities are being challenged, re-affirmed and reconfigured. The article argues that men experience a loss of status as breadwinners and a rupture of their sense of masculine identity in the reconstruction of life in the diaspora. Conditions in the hostland, in particular, women's breadwinner status and the changing gender relations, threaten men’s ‘hegemonic masculinity’ and consequently force men to negotiate respectable forms of masculinity

Youth mobilities, crisis, and agency in Greece: second generation lives in liminal spaces and austere times

This paper explores various dimensions of “mobility” and “agency” among second-generation immigrants in Greece who have experienced the economic crisis throughout their studies at Higher Education Institutions. Following their studies in Greece, second-generation youth migrants graduated at a time when the crisis had already been leading hundreds of thousands of mostly highly skilled Greeks to emigration, resulting in a severe “brain drain” for Greece. First-generation immigrants’ investment in their children’s education has been vital as an integration strategy and as a means of achieving social mobility. It has also been an asset during crisis times when the prospect of re-migration seems more than a possible option setting new challenges for youth mobility on a local, global, and transnational level. Nevertheless, the vast majority of our participants manifest their will to remain in Greece and struggle for their future in the host country. Through in-depth interviews with 130 participants, all second-generation Albanian, Bulgarian, and Romanian immigrants in Greece, 30 born in the host country and the rest in the country of origin, the paper addresses youth agency in relation to geographical mobility, education, and personal development

Post-socialist narratives of being, belonging and becoming: Eastern European women migrants and transformative politics in an era of European crises

This paper draws from an oral history project on ‘Gendered Histories of Resilience and Resistance: Eastern European Women’s Narratives of Mobility and Survival’, which is a narrative ethnography of Albanian, Bulgarian, Romanian and Polish migrant women living in Greece. The paper explores these women’s life stories, memories and experiences, in both their ancestral homelands as well as country of settlement, in order to examine the intersections of gender and identity in how the recollection of socialist pasts informs the understanding of living present and future capitalist lives. The diverse, compelling but also competing accounts of women’s childhood and early adult lives in socialist times in their Eastern European countries of origin is an intriguing way to explore issues of being, belonging and becoming. Discussions on feminism and identity are also revealing as they highlight the discourses and political projects at the intersections of personal experiences with broader socio-cultural and economic fields, in particular as regards the context of migration and the current crisis in Greece

'A window to knowledge is a window to the world': socio-aesthetics, ethics and pedagogic migrant youth journeys in crisis-shaped educational settings in Greece

This paper explores the processes, tensions, opportunities and constraints that migrant youth in Greek higher educational institutions experience at the present time which are characterised by social crises, economic austerity and political instability. In doing so, we also put forward an agenda of critical and feminist pedagogies in developing inclusive spaces of educational citizenship and social justice. Building on a larger collaborative study on youth and migration, this paper draws on a sample of 130 interviews with women and men second generation migrants who are currently, or have been in the past, university students at various institutions in Greece. Migrant youth expanding on their aspirations and capacities harness a developmental pathway of cosmopolitan pedagogies which alter their circumstances and social possibilities. The paper advances alternative discourses in crafting spaces of anti-oppression in the academy through a feminist lens which will cultivate learning communities of equity, justice and reflexivity

'Diverse mobilities': second-generation Greek-Germans engage with the homeland as children and as adults

This paper is about the children of Greek labour migrants in Germany. We focus on two life-stages of ‘return’ for this second generation: as young children brought to Greece on holidays or sent back for longer periods, and as young adults exercising an independent ‘return’ migration. We draw both on literature and on our own field interviews with 50 first- and second-generation Greek-Germans. We find the practise of sending young children back to Greece to have been surprisingly widespread yet little documented. Adult relocation to the parental homeland takes place for five reasons: (i) a ‘search for self’; (ii) attraction of the Greek way of life; (iii) the actualisation of the ‘family narrative of return’ by the second, rather than the first, generation; (iv) life-stage events such as going to university or marrying a Greek; (v) escape from a traumatic event or oppressive family situation. Yet the return often brings difficulties, disillusionment, identity reappraisal, and a re-evaluation of the German context
