Many practical problems in engineering consist of a structure surrounded by a fluid. These are all from the theoretical point of view fluid-structure interaction problems, in which the movement of the structure influences the flow field of the fluid and vice versa. In this contribution the structure is described in a total Lagrangian representation based on velocities and the 2nd Piola-Kirchhoff stress state as primal variables in a hybrid-mixed formulation, while the fluid is modelled via the incompressible Navier-Stokes equations with velocities and pressure as unknowns. The governing equations of fluid and structural dynamics are uniformly discretised using space-time finite elements [1]. The discretised model equations of the fluid are stabilised using a SUPG/PSPG approach. Shape and test functions are continuous within the space-time slabs, while across the space- time slabs the shape and test functions are continuous only in space, but discontinuous in time yielding a time-discontinuous Galerkin approach. The space-time discretisation of the coupled system with velocities and pressure as remaining unknowns lays the basis for a mathematically profound analysis due to its methodical uniformity. During the mesh generation of the fluid-structure problem a fitting mesh at the conjoint interface of fluid and structure is generated ensuring natively the geometric continuity. In the discretised flow domain, which model equations are formulated in the Eulerian framework, a mesh-moving scheme needs to be applied to avoid severe mesh distortions. In case of large but regular structural displacements a discontinuous mesh-moving scheme like the Shear-Slip Mesh Update Method (SSMUM) is applicable [2]. In order to increase robustness and conservation behaviour of the classical SSMUM a modification based on the space-time discretisation of the problem described above is investigated. In the Space- Time SSMUM (ST-SSMUM) the alteration of the spatial connectivity takes place continuously in the space-time domain. By avoiding sudden changes in the spatial connectivity between two adjacent space-time slabs any difficulty in evaluating the jump term is circumvented. The properties of the introduced ST-SSMUM is shown by a computation of the flow field of a rotating impeller, which can be interpreted as a simplified water turbine or blood pump. [less ▲]

Integrating migrants into national labour markets is arguably of perennial concern for governments across Europe. Self-employment or entrepreneurship has been identified as a possible route to active professional participation (Light & Gold 2001, Leicht et al. 2012). Studies of immigrant businesses identified multilingual language proficiency as an important aspect of their success (Light 2007). On the one hand, heritage language proficiency may provide the means to maintain advantageous social network ties to coethnic business partners (Aldrich & Waldinger 1990). On the other, sustainable growth is apparently directly related to certain levels of proficiency of the main language of the economy (Nekvapil 2009, Kloosterman 2010). While studies in applied linguistics have stressed the pragmatic impact of multilingualism in service encounters in entrepreneurial contexts (e.g. Leung 2009, Collier 2006, 2010, 2011), I believe that more work needs to be done in accounting for the value of multilingualism across the whole range of linguistic practices that self employment requires. The aim of this presentation is to take a first step into this direction by investigating the ways immigrant business owners navigate professional practices linguistically. For this presentation I intend to examine autobiographic narratives of five successful female business owners with Asian roots who have set up businesses in the borderlands of Germany, Luxemburg and France, so as to reconstruct the ways these individuals employ and develop their linguistic repertoires in connection to their workplace practices. The paper shall thus shed some empirical light on commonly held assumptions about heritage language use as an asset and majority language(s) use as a problem in such professional settings. [less ▲]

The goal of my research project is to analyse processes of (re)productions of regions within the biogas sector and illustrate different development paths. The case study is located in the border area of Luxembourg and Germany. The application of renewable energies in decentralised ways is considered being the ultimate chance for a long lasting prosperous and environmentally sound regional development, since they trigger various positive effects (e. g. regional value added, less power loss, lower susceptibility to discrepancies, substitution of energy imports, job creation etc.). To effectively and efficiently implement decentralised renewables, such as bioenergy, photovoltaics or wind power, the interaction and collaboration of various regional and sub-/supra-regional actors is necessary. They all – at least slightly - differ in their perspectives on challenges for energy supply as well as on the region itself. Hence, questions of space and scale arise: If the transition to renewable energies can be achieved by a decentralised utilisation, where does this take place, what is the region for implementing them? Or vice versa – my core research question: Which processes of regionalisations are initiated through the utilisation of renewable energies, especially biogas production? To address this question, I apply a multi-theory and multi-method approach. In theoretic terms, I put on two “glasses”. On the one hand, I analyse institutional and structural conditions that frame processes of regionalisations in the biogas economy and how these conditions relate to socio-technical developments. My theoretical approach is based on evolutionary institutionalism and socio-technical transition studies. Therefor, industrial networks and strategic games, techno-scientific knowledge, cultural and symbolic meanings, sectorial policies, as well as markets and user practices are important elements of analysis. It is important to be aware of the dynamic dimension of frameworks (development and change / evolution), the concurrence of political, social, economic and technical processes, the long lasting transformations, and the spatial differences (context) (cf. Boschma/Frenken, 2006; Glückler, 2007; Hayter, 2004; Jones/Murphy, 2010; Truffer, 2008) – that are typical not only for decentralised technologies. My focuses of investigation from this perspective are threefold. First, I explore the legal framework, contractual agreements and association/group structures that relate to biogas production. Second, I study the political, social, and economic developments in the biogas sector and their effects on technological developments. And third, I analyse the alignments of institutional structures and individual decision making with new biogas technologies. I apply a retrospective perspective, looking back at the period from the mid-1990s (liberalisation of EU energy market, upcoming of bioenergy) till today. On the other hand, I shift the focus to economic practices and everyday actions of actors in the biogas economy (e.g. operators, investors). The main goals are to analyse the economic utilisation of spatial categories and contexts, and to uncover the relationship of economy, action and spatial references. In which ways do everyday actions constitute, reproduce and transform scale and space metaphors („regions“)? Which action responses do they trigger? Which external regionalisations influence the actors’ decisions – regionalisations “done” by non-economic actors (e.g. planners, politicians, NGOs, media)? How do biogas producers perceive external regionalisations? I focus on processes of constitution and reproduction of different types of energy regions and the modes and patterns, in which practices influence the processes of regionalisations – following Benno Werlen’s theory of everyday regionalisations (Werlen, 1999; 2007; 2010). In terms of methodology I am currently using two different concepts. Since I apply, on the one hand, an action oriented approach to regionalisations, I conduct interviews with actors in the biogas economy to investigate elements such as perceptions, performances, patterns, power relations, or intensions. I will set these elements in the context of scale and space metaphors: doings and sayings with spatial references or connotations – whether explicit or implicit. On the other hand I apply document analysis for extracting different “regions” that are expressed, for example, in strategy papers, business reports, official statements, laws, directives, planning documents, or media coverage. I will, in another step, confront experts with the findings from the second data source to examine, how they – if at all – perceive them and how they incorporate them into their practices. The findings and theoretical thoughts shall lead to a better understanding of processes of regionalisations and different concepts or connotations of the region, for theoretical purposes as well as to inform policy making. Furthermore, I aim at enriching or even opening the floor for two discussions. At the one hand, how theories of economic practice might enrich evolutionary approaches to understand economic processes. At the other hand – and in the context of a energy / bioenergy debate – how a new perspective on the relations between economy and environment can help us to conceptualise an Environmental Economic Geography that takes Economic/Corporate Greening, Environmental Governance, Facets of North-South-Relations and other Greening Contexts serious.

Les sites principaux d’un constructeur aéronautique européen sont implantés en Allemagne et en France. Cependant, comme le stipulent certains documents internes l’anglais est la langue officielle de l’entreprise. Les déclarations des salariés deviennent plus flottantes quand on en vient au fonctionnement par département. L’équipe de travail est présentée par les personnes interviewées comme une zone à part par ses propres règles linguistiques. Nous avons analysé les tensions entre le prescrit et l’observable notamment grâce à l’étude du « mais » des entretiens. Lorsqu’ils abordent le sujet de la dimension personnelle, les salariés sont souvent tentés de se justifier de certains choix qui sont faits pour accomplir leurs tâches de travail au mieux. Ces choix dépendent de la compétence plurilingue et sont parfois mal assumés si cette dernière est limitée. Cette constatation nous invite à repenser les schémas de formations encore employés aujourd’hui. [less ▲]

In the wake of globalization, technological and infrastructural changes have substantially increased the mobility of migrants all over the world. Across Europe these developments have added more variety to migration populations, a fact that has been identified as super-diversity (Vertovec 2007, 2009). Studying linguistic diversity and variation, sociolinguists have begun the examination of language in super-diverse settings, in order to describe the interweaving and meshing of languages, identities, and language practices (Creese & Blackledge 2010, Blommaert & Rampton 2011). One particularly interesting field within which migrants make use of these transnational and ethnic resources is self-employment (Light & Gold 2000). In this professional domain the knowledge of (multiple) languages and ways of communicating has been presented as an asset and a challenge. To date studies that investigate the linguistic life worlds of migrant entrepreneurs in detail are only few in number. Focusing on the border region between Germany and Luxembourg, this paper aims to explore two aspects of the link between language use and self-employment among non-EU migrants. Firstly, I intend to understand the entrepreneurs’ linguistic trajectories into self-employment. Another aim is to explore how the professional endeavour has shaped each migrant’s linguistic repertoire. The analysis is part of a dissertation research project investigating the language practices of non-EU ethnic entrepreneurs. Following the approach of linguistic ethnography (Creese 2008), oral narrative interviews were part of the data generation. The analysis was informed by the study of language biographies as described by Franceschini (2002) with the aim of focusing on the entrepreneurs’ everyday reasons and experiences using and learning languages at and for their professional practices. The results show that for these migrant entrepreneurs the workplace becomes a site of informal acquisition of the majority languages. On the other hand language practices linked to business activities are sites of language maintenance of heritage languages. The data thus reveals patterns of language diversity management that is directly connected to the entrepreneur’s practical, occupational needs. Moreover, it shows the usefulness of employing language biographies as one of the methods to explore language use and learning in super-diverse workplace settings. [less ▲]

The study examined the effect of language and presentation mode on numerical processing skills in German-French bilinguals. This bilingual combination is particularly interesting because the order of two digit number words is inversed in both languages: decade-unit in French but unit-decade in German. Further, previous studies used written number word presentations as verbal notation to activate language, which are, however, rarely used in everyday life. The present study therefore tackled the question whether two-digit magnitude judgments are affected by the presentation mode (visual Arabic vs. auditory words) and the language (German vs. French)? Data stem from proficient German-French bilinguals (mean age: 25,3 years. The within-subject design involved two-digit number pair comparisons presented visually and auditory in German and in French. In line with previous studies, participants responded faster and more accurately on compatible than on incompatible trials in the visual Arabic presentation mode in both languages (compatibility effect): In compatible number pairs, the decades and units concord to the same magnitude decision (e.g. 23_57; decade: 2<5 and unit:3<7) whereas decade and units discord (47_82; decade: 4<8 but 7>2) for incompatible number pairs. In the auditory mode, the results showed a tendency for a regular compatibility effect in German and an inverse compatibility effect in French with participants responding faster on incompatible trials suggesting that bilinguals process numerical tasks in the language of presentation similar to monolinguals using the same language. Conclusively, the results imply differential numerical processing according to the presentation mode (visual Arabic vs. auditory words) and the language (German vs. French). [less ▲]

How do number-space interactions develop from childhood to adulthood? The SNARC effect (Spatial Numerical Association of Response Codes) reflects the finding that participants respond faster to small numbers with their left hand and to large numbers with their right hand during a number classification task. Typically assessed through magnitude-independent parity judgment tasks, the SNARC effect is thought to show the automaticity of the number-space link. Using a parity task on children Berch et al. (1999) found a SNARC effect no earlier than from 9.2 years onwards. However, we hypothesise that parity judgments might be inappropriate to assess younger children. Therefore a more age-apropriate colour judgment task (implicit) and a magnitude judgement task (explicit) were designed and tested on 363 children from kindergarten to Grade 6 (5.8-12 years). The experimental tasks were complemented by a brief assessment of arithmetic skills. The results revealed overall significant SNARC effects [colour task t(355)=2.6, p<0.01; magnitude task t(340)=4.7, p<0.001], which interacted with grade [colour task F(6,355)=2.18; p<0.05; magnitude task F(6,340)=2.09; p=0.05]. Most interestingly, even the kindergartners already display both effects [colour task t(28)=1.96; p<0.05; magnitude task t(24)=1.7; p=0.05]. These results show explicit and implicit access to numerical magnitude in children as young as 5.8 years. [less ▲]

Number processing interacts with space encoding in a wide variety of experimental paradigms. Most intriguingly, the passive viewing of uninformative number symbols can shift visuo-spatial attention to different target locations according to the number magnitude, i.e. small/large numbers facilitate processing of left/right targets, respectively. The brain architecture dedicated to these attention shifts associated with numbers currently remains unknown. Evoked potential recordings indicate that both early and late stages are involved in this spatio-numerical interaction, but the neuro-functional anatomy needs to be specified. Here we use, for the first time, functional magnetic resonance imaging (fMRI) to investigate attentional orienting following uninformative Arabic digits. We show that BOLD response in occipital visual regions was modulated by the congruency between digit magnitude (small/large) and target side (left/right). Additionally, we report higher BOLD responses following large (8, 9) compared to small (1, 2) digits in two bilateral parietal regions, yielding a significant effect of digit magnitude. We propose and discuss the view that automatic encoding of semantic representations related to number symbols in parietal cortex lead to shifts in visuo-spatial attention and enhanced visual processing in the occipital cortex according to number-space congruency rules.

At the turn of the millennium, it was decided that Luxembourg should target four percent economic growth in order to best sustain existing quality of life standards. This target has largely been met as Luxembourg’s growth, which was mainly driven by the financial industry and a non-resident labour force, has averaged around five percent annually. Emerging out of a quasi-rural and industrial landscape, Luxembourg has come under the considerable growth pressures associated with a tertiary economy. It is thus facing particular challenges with respect to sustainable development. As a result, Luxembourg planning officials formulated spatially integrative sustainable development guidelines that postulate a polycentric growth model while targeting sufficient provision of housing, preventing sprawl, preserving green spaces, densifying growth poles, and enhancing public transportation. This research examines these strategies that are designed to manage growth and compares it with existing local land use practices. The small size of the Grand Duchy and narrow functional relationships between the capital city and the rest of the country justify treating the whole country as an integrated city region. The absence of a regional administrative level implies direct and strong policy dependencies between the national political and administrative levels. In this paper, particular attention is given to national policy mechanisms and their translation and implementation at the local level. The analysis reveals a number of challenges particularly with respect to enforcement and interpretation related to existing power relationships and different development visions adopted by the municipalities. Observations of the organization and capital flows of retail and commerce, housing and real estate development patterns, and the governance patterns that structure both illustrate how national smart growth policies of integrated smart growth can turn into grassroots sprawl or a governance of dispersal.

This paper presents progress achieved within the context of SUSTAINLUX (a research project funded by the Fonds National de la Recherche Luxembourg) and collaborative studies with the Worcester Polytechnic Institute.The research has aimed at critically examining the approach of sustainable development, in the context of Luxembourg’s urban and regional governance structures (Carr, Hesse, and Schulz 2010), that have transformed and rescaled (Brenner 1999) against tertiarization of the economy, and Europeanization of the political arena (Schulz 2009; Becker forthcoming) – processes that have had significant impact on the affordability of housing and infrastructure for mobility. To date, the research methods have included mapping the literature and actors relevant to the sustainable integrated development discourse in Luxembourg, performing interviews with practitioners in the field and exploring the role and limitations of this normative discourse in Luxembourg’s social spatial transformation (Carr 2011). Particular attention was paid to structures of decision-making and its relationship to the prevailing real estate market. In addition, comparative research was performed in collaboration with Prof. Krueger. This presentation will talk about the results and conceptualize them within the framework of policy mobility, as has been discussed in recent literature such as Ward (2006), Temenos and McCann (forthcoming), and González (2010). In this way, clear barriers to implementation to sustainable development goals can be identified. References Becker, Tom. forthcoming. “Europäisierung der Städtepolitik ?

Whereas reasons for having children, i.e. positive VOC, have been a central focus within the framework of the Value-of-Children approach, reasons for not having children, namely negative VOC, have been given less attention so far. Perceived negative aspects of parenthood may, however, be of particular importance for the individual decision of having children or not, and may be related to the actual quality of intergenerational relationships. The aim of the present study was therefore to focus explicitly on negative VOC and to examine in how far negative aspects of having children are related to further variables characterizing intergenerational relationships in three different cohorts (mothers of adolescents, mothers of small children and adolescents) living in western and eastern Germany as well as in Poland. Participants took part in the cross-cultural and interdisciplinary Value-of-Children study. The study design allowed taking into account not only generational/cohort and country effects, but also effects of social change. A comparison of the reasons for not having children (negative VOC) between the different subsamples showed that whereas roughly the same negative aspects were most prominent in all subsamples (with problems related to job being rated highest by all participants), young mothers from West Germany and mothers from Poland as well as adolescents from all three subsamples were overall more bothered about having children compared to old and young mothers from East Germany and old mothers from West Germany. Higher negative VOC went along with mothers’ reported ideal number of children or with the actual number of children in the German mother subsamples. Negative aspects of having children had also an impact on adolescents’ ideas about having children: Whereas in Germany, adolescents’ intention of having children (or not) in the future was related to the level of negative VOC, in Poland, apart from that also the intended number of future children was related to negative VOC.

I will be discussing the nucleation process in a system composed of mono-disperse hard spheres initially in an over-compressed fluid state. Molecular dynamics simulations are presented for the homogeneous system and the dynamics and structure of the forming nucleus including the corresponding nucleation rates are discussed. In comparison to the studied homogenous nucleation event we will extend this system and introduce a substrate to study its influence onto nucleation within the fluid. In this case the substrate is made up of the same type of spheres held fixed in space throughout the simulation process on a triangular lattice modeling a crystalline surface. In general heterogenous nucleation, due to surfaces, walls as well as confinement are of great importancein experiments of colloidal suspensionsbecause strong effects are observed. In our case the substrates influence is studied by varying the substrate lattice constant as well as the fluid density. We observe qualitatively different dynamical regimes that will be discussed in detail. [less ▲]
