In May 2014, a Language Centre has been established at the University of Luxembourg, which aims to support academic language skills in the three official university languages English, French and German. Shortly after its foundation, the Language Centre conducted a university-wide needs analysis, to establish the needs for language support. This paper presents findings of this investigation that report on the role German language plays at the University of Luxembourg. Moreover, it will discuss measures and strategies to support German language acquisition within the scope of the university’s multilingual orientation. [less ▲]

Die Stellung des Deutschen an der mehrsprachigen Universität Luxemburg Mehrsprachigkeit ist ein Identitätsmerkmal der Universität Luxemburg, das sich sowohl im beruflichen Alltag der Universität als auch in ihren zahlreichen mehrsprachigen Studiengängen wiederspiegelt. Um die mehrsprachigen Kompetenzen von MitarbeiterInnen und Studierenden zu fördern, wurde im Mai 2014 das Sprachenzentrum der Universität Luxemburg gegründet. Ein Fokus des Zentrums liegt auf der Unterstützung wissenschaftlicher und berufsspezifischer Sprachkompetenzen in den Universitätssprachen Englisch, Französisch und Deutsch sowie auf dem Ausbau mehrsprachiger Kompetenzen. Zusätzlich werden allgemeinsprachliche Kurse für die eben genannten Sprachen sowie für Luxemburgisch angeboten. Im Wintersemester 2014/15 hat das Sprachenzentrum eine umfangreiche und differenzierte Befragung durchgeführt, um den Bedarf für Sprachunterstützung an der Universität abzuschätzen. In der Studie wurden einerseits 24 teilstrukturierte Interviews mit den Studien¬programm¬¬direktorInnen der Fakultäten durchgeführt und andererseits mittels Online-Fragebogen alle MitarbeiterInnen und alle Studierenden der Universität befragt. In diesem Vortrag werden Ergebnisse aus dieser Bedarfserhebung präsentiert, die Aufschluss über die Stellung des Deutschen an der Universität Luxemburg geben. Während im Französischen durchaus mehrere Sprachniveaus zu finden sind und das Englische hauptsächlich auf mittlerem und hohem Sprachniveaus vertreten ist, beherrschen MitarbeiterInnen und Studierende Deutsch entweder auf sehr hohem Niveau oder haben keine oder nur geringe Deutschkenntnisse. Studierende (37%) sind gegenüber MitarbeiterInnen (29%) eher dazu bereit, Deutsch zu lernen, wobei beide Gruppen tendenziell eher ihre mündlichen als ihre schriftsprachlichen Kompetenzen verbessern wollen. Deutsch ist in den Studienprogrammen die am wenigsten etablierte Sprache, wobei große Unterschiede zwischen den drei Fakultäten bestehen. In den beiden Fakultäten, in denen Deutsch als Wissenschaftssprache kaum vertreten ist, wird die Notwendigkeit, dass Studierende Deutschkenntnisse erwerben, von Lehrenden und Studierenden allerdings sehr unterschiedlich eingeschätzt.

Breast cancer stem cells (CSCs) are thought to drive recurrence and metastasis. Their identity has been linked to the epithelial to mesenchymal transition (EMT) but remains highly controversial since-depending on the cell-line studied-either epithelial (E) or mesenchymal (M) markers, alone or together have been associated with stemness. Using distinct transcript expression signatures characterizing the three different E, M and hybrid E/M cell-types, our data support a novel model that links a mixed EM signature with stemness in 1) individual cells, 2) luminal and basal cell lines, 3) in vivo xenograft mouse models, and 4) in all breast cancer subtypes. In particular, we found that co-expression of E and M signatures was associated with poorest outcome in luminal and basal breast cancer patients as well as with enrichment for stem-like cells in both E and M breast cell-lines. This link between a mixed EM expression signature and stemness was explained by two findings: first, mixed cultures of E and M cells showed increased cooperation in mammosphere formation (indicative of stemness) compared to the more differentiated E and M cell-types. Second, single-cell qPCR analysis revealed that E and M genes could be co-expressed in the same cell. These hybrid E/M cells were generated by both E or M cells and had a combination of several stem-like traits since they displayed increased plasticity, self-renewal, mammosphere formation, and produced ALDH1+ progenies, while more differentiated M cells showed less plasticity and E cells showed less self-renewal. Thus, the hybrid E/M state reflecting stemness and its promotion by E-M cooperation offers a dual biological rationale for the robust association of the mixed EM signature with poor prognosis, independent of cellular origin. Together, our model explains previous paradoxical findings that breast CSCs appear to be M in luminal cell-lines but E in basal breast cancer cell-lines. Our results suggest that targeting E/M heterogeneity by eliminating hybrid E/M cells and cooperation between E and M cell-types could improve breast cancer patient survival independent of breast cancer-subtype.

Design fixation is a phenomenon that negatively impacts design outcomes, especially when it occurs during the ideation stage of a design process. This study expands our understanding of design fixation by presenting a review of de-fixation approaches, as well as metrics employed to understand and account for design fixation. The study then explores the relevant ideation approach of Design-by-Analogy (DbA) to overcome design fixation, with a fixation experiment of 73 knowledge-domain experts. The study provides a design fixation framework and constitutes a genuine contribution to effectively identify approaches to mitigate design fixation in a wide range of design problems. [less ▲]

Scanning tunneling microscopy is used to quantify step-edge sputtering of Pt(111) at 550 K by grazing incidence ion bombardment with 5 keV Ar(+) ions. For bombardment conditions causing negligible erosion on terraces, damage features associated with step bombardment allow us to visualize step retraction and thus to quantify the step-edge sputtering yield. An alternative method for step-edge yield determination, which is applicable under more general conditions, is the analysis of the concentration of ascending steps together with the removed amount as a function of ion fluence. Interestingly, the azimuthal direction of the impinging ions with respect to the surface significantly changes the sputtering yield at step edges. This change is attributed to the orientation dependence of subsurface channeling. Atomistic insight into step-edge sputtering and its azimuthal dependence is given by molecular dynamics simulations of ion impacts at 0 and 550 K. The simulations also demonstrate a strong dependence of the step-edge sputtering yield on temperature. [less ▲]

The study of how molecules adsorb, diffuse, interact, and desorb from imperfect surfaces is essential for a complete understanding of elementary surface processes under relevant pressure and temperature conditions. Here we use first-principles calculations to study the adsorption of benzene and naphthalene on a vicinal Cu(443) surface with the aim to gain insight into the behavior of aromatic hydrocarbons on realistic surfaces at a finite temperature. Upon strong adsorption at step edges at a low temperature, the molecules then migrate from the step to the (111) terraces, where they can freely diffuse parallel to the step edge. This migration happens at temperatures well below the onset of desorption, suggesting a more complex dynamical picture than previously proposed from temperature-programed desorption studies. The increase of the adsorption strength observed in experiments for Cu(443) when compared to Cu(111) is explained by a stronger long-range van der Waals attraction between the hydrocarbons and the step edges of the Cu(443) surface. Our calculations highlight the need for time-resolved experimental studies to fully understand the dynamics of molecular layers on surfaces. © 2015 American Physical Society. [less ▲]
