Le Roman de la Rose (premier tiers du XIIIe siècle), véritable somme du code amoureux chevaleresque et de son imaginaire érotique, montre une femme idéalisée, mais soumise au désir masculin. La rose, métaphore du corps féminin, n’est-elle pas choisie et convoitée par le héros, mais aussi emprisonnée et défendue au nom de la vertu ? Il faut attendre le XVIe siècle et une femme aussi émancipée que Louise Labé, par exemple, pour voir mis en vers dans ses sonnets les émotions et désirs amoureux féminins, aussi ardents et assoiffés de liberté que ceux de l’autre sexe.

I will discuss the crystallization process in suspensions of hard particles far from equilibrium. The suspensions of hard particles, iniitially prepared in an equilibrium fluid state, are subjected to a time dependent over-compression protocol. During this process formation of crystallites and dynamic arrest take place. \\ This solidification process will be investigated in the framework of non-equilibrium fluctuation relations. For a given system driven far from equilibrium these relations state symmetries of the distribution of dissipated heat or mechanical work and ultimately relate to equilibrium free energy differences. The distribution of mechanical work, also experimentally accessible, contains important information about the evolution of crystallites and disorder in the system. Therefore, studying the distribution of mechanical work will offer new insights to the dynamical properties of the crystallization process and relate structural changes to dissipated energy far from equilibrium. \\ This presentation is based on ongoing research in the Theoretical Softmatter group at the University of Luxembourg.

New media have become an essential part of everyday life and regular users are labeled as ‘(inter)net generation’ (Tapscott, 1998; Buckingham, 2007; Montgomery, 2007; Beetham & Sharpe, 2007) or ‘digital natives’ (Prensky, 2001, 2009, 2010; Benett et al., 2008; Helsper et al., 2010). Interactive new media (Manovich, 2003; Crook, 2008; Redecker et al., 2009) and the social web (Bevan, 2010) are blurring the boundaries between learning and social or leisure activities. By transforming conventional media monologues into social media dialogues, they are expanding opportunities of collaborative authoring and peer exchange within communities of prod-users (Bruns, 2008; Rheingold, 2008). They generate a high growth of social interactions and mutual exchanges among members (Ito et al., 2009; Kirschner & Karpinski, 2010; Eynon & Malmberg, 2011). Participants feel some degree of social connection with one another, mutually value contributions and support less competent members through tutoring practices. On the basis of this “participatory culture” (Jenkins et al., 2007) radical new learning opportunities (Ala-Mutka, 2010) take shape. The participatory and active role, which these tools allow users to take, make them interesting for learner-centred approaches in higher education. The regular use of ICT and web technologies (Anderson, 2007) in educational institutions is far from common and rarely goes beyond rudimentary functions or the use of limited resources (Cox et al., 2003a, 2003b; Cuban, 2003). The present contribution discusses results achieved by students using web 2.0 applications within academic programs such as blogs, video sharing tools and social net working sites. They evidence beneficial effects on processes of learning, socialisation and conviviality (Caire 2010) and skills such as critical thinking, problem solving, communication, and collaboration as emphasised by 21st century frameworks (Voogt & Pareja Roblin, 2012) . Furthermore, the contribution will raise questions about barriers and strategies for integrating learning 2.0 effectively into higher educational contexts. It emphasises the systemic tensions to overcome, pedagogical practices to promote and conviviality potentials (Caire, 2010) to stimulate by fair digital participations, collaborations and interactions in highly multilingual and multicultural contexts.

This presentation explores constructions of 'female' spaces in literary texts of the turn of the 19th century in relation to the amalgamation of gender, desire and biological sex in the medical discourses of the period. Rereading 'The Yellow Wallpaper' involves reading it alongside other texts that draw on the notion of entrapment to articulate the difficulties faced by female artists of the late nineteenth century.

Wir gehen davon aus, dass Kinder eine Sprache lernen, wenn sie diese in unterschiedlichen Situationen und mit unterschiedlichen Personen benutzen, um etwas mitzuteilen, was ihnen wichtig ist. Zuhören, Kollaboration, Autonomie und Respekt sind wichtige Kompetenzen, die man in der Schule entwickeln muss. Da diverse (neue) Medien zum soziokulturellen Alltag der Kinder gehören, sollen sie auch im Sprachunterricht eingesetzt werden. Die Arbeit mit den Kindern in der Schreibwerkstatt und mit der iPad App iTEO (traitement de texte oral) basierten und basieren auf soziokonstruktivistischen Prinzipien. Die Ergebnisse unserer Studien zeigen, dass Kinder, die gemeinsam mit Kameraden Geschichten erzählten, ihre Sprache entwickelten (z.B. Wortschatz, Grammatik, diskursive Kompetenzen), sich metalinguistisches Wissen aneigneten und Lernstrategien erwarben. Das Ziel dieses Workshops ist es, die Konzepte 'Storying' und Schreibwerkstatt vorzustellen, das Programm iTEO auszuprobieren und mündliche und schriftliche Textproduktionen von Kindern zu analysieren.

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 ▲]

In the context of the transformation process currently taking place in the energy production sector, energy gained from renewable power sources shall replace the present mixture, which mostly relies on fossil burnings. Therefore, in the future most of the energy shall be gained by harvesting power from sun, wind or water, geothermal heat or biomass. In case of converting energy from wind into electrical power wind turbines are used in general, while hydropower turbines are the state-of-the-art machinery to derive energy from running water. In order to convert the potential energy from running water as well water wheels pose the method of choice. Turbines in air or water represent mechanically a two-field system, in which the structure of the turbine is surrounded by a streaming fluid. Due to the elasticity of the rotor blades the stresses of the fluid onto the structure deform the blades, which in return yield a time-dependent flow domain. Therefore turbines in a streaming fluid represent a typical example of fluid-structure interaction. Furthermore, in case of water wheels the surrounding air as third field and additional fluid phase comes into play introducing a free surface. In this contribution the governing equations of incompressible fluid flow are presented using primal variables and discretised via the space-time finite element method [3]. The discretised model equations of the fluid are stabilised using an 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. Due to the moving rotor blades a mesh moving technique needs to be incorporated into the computational set-up. Considering the occurring large but regular displacements of the flow boundary arising from the rotating rotor blades the shear-slip mesh update method (SSMUM) [1] as discontinuous mesh moving technique is applied. In case of water wheels the free surface is described implicitly via a Level-Set function [2] yielding a single fluid phase with almost discontinuous density and viscosity. The verification and validation of the developed numerical scheme is carried out with the help of computing classical benchmark problems as well as via a comparison to existing experimental data.

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 ▲]
