Recently, many researchers are working on semantics preserving model transformation. In the field of graph transformation one can think of translating graph grammars written in one approach to a behaviourally equivalent graph grammar in another approach. In this paper we translate graph grammars developed with the GROOVE tool to AGG graph grammars by first investigating the set of core graph transformation concepts supported by both tools. Then, we define what it means for two graph grammars to be behaviourally equivalent, and for the regar/ded approaches we actually show how to handle different definitions of both - application conditions and graph structures. The translation itself is explained by means of intuitive examples. [less ▲]

We produce and investigate liquid crystal shells with hybrid alignment—planar at one boundary, homeotropic at the other—undergoing a transition between the nematic (N) and smectic-A (SmA) phases. The shells display a dynamic sequence of patterns, the details depending on the alignment agents and on the diameter and thickness of the shell. In shells of sufficient diameter we typically find a transient striped texture near the N–SmA transition, stabilising into a pattern of tiled, more or less regularly spaced focal conic domains in the SmA phase. The domain size and spacing decrease with reduced shell thickness. In case of strong homeotropic anchoring at one boundary and small shell size, however, the increased curvature favors homeotropic against planar alignment in the smectic phase, and the shell then tends to adapt to complete homeotropic alignment at the final stage of the transition. This is the first study of hybrid-aligned smectic shells and the results constitute a beautiful demonstration of the capacity for dynamic structure formation and reformation via self-assembly in soft matter. The new patterns extend the range of arrays of topological defects that can be realised with liquid crystals in spherical morphology and the correlation between the feature arrangements and the variable parameters of the shell and its environment opens a route towards tunability. However, the observed strong impact from increasing curvature, even for these rather large shells, indicates that the choice of alignment agents inducing planar or homeotropic alignment with varying strength will become critical when targeting the most attractive colloidal size scale of about a micron or smaller.

We demonstrate how micromagnetic simulations can be employed in order to characterize and analyze the magnetic microstructure of nanocomposites. For the example of nanocrystalline Nd-Fe-B, which is a potential material for future permanent-magnet applications, we have compared three different models for the micromagnetic analysis of this material class: (i) a description of the nanocomposite microstructure in terms of Stoner-Wohlfarth particles with and without the magnetodipolar interaction; (ii) a model based on the core-shell representation of the nanograins; (iii) the latter model including a contribution of superparamagnetic clusters. The relevant parameter spaces have been systematically scanned with the aim to establish which micromagnetic approach can most adequately describe experimental data for this material. According to our results, only the last, most sophisticated model is able to provide an excellent agreement with the measured hysteresis loop. The presented methodology is generally applicable to multiphase magnetic nanocomposites and it highligths the complex interrelationship between the microstructure, magnetic interactions, and the macroscopic magnetic properties.

Previous research has shown that normative appeals to engage in environmentally friendly behavior were most effective when they were accompanied by a provincial norm (e.g., when norms matched individuals’ immediate situational circumstances). Analyzing hotel guests’ towel-use during their stay, the current study tests whether messages employing provincial norms were more effective in reducing towel-use than standard environmental messages. In line with previous findings, guests of two hotels used significantly fewer towels when provincial normative appeals—rather than standard environmental messages—were communicated. These findings corroborate to the body of research demonstrating the power of social norms on environmental behavior. [less ▲]

Anyone involved in entrepreneurial learning, teaching and research will be aware of the power of a good story about business venturing. The continuous supply of personal stories and accounts of business venturing in bookshops, airport lounges, the business press, television dramas or documentary programmes is evidence of the popular readership of entrepreneurial topics sometimes inspiring people to ‘have a go’ for themselves. But narrative accounts are often maligned in entrepreneurship studies for their anecdotal character and inability to say anything significant beyond the person telling their personal story. In this article, the benefits of a narrative style of inquiry for entrepreneurship studies are considered. This is done with reference to the Marvel Mustang account of business venturing. By relating to narrative and reader response theory, consideration is given to the function that the (Marvel Mustang) text has for the reader and how the reader (and not the text) is the key source of meaning about the practices we associate with entrepreneurship. In taking this emphasis, it is possible to understand the processes that facilitate the ‘stretching away’ of little entrepreneurial stories into transforming relations that go beyond the producer of the story and which ‘pull in’ or connect other people that are unrelated to the story. Narrative analysis helps inquirers to move beyond the ‘what’ and the ‘how’ of entrepreneurship and to be able to answer theoretically ‘why’ such processes migrate and stretch across different cultures and contexts.

Si l’on admet que la littérature migrante transcrit la mondialisation et l’interpénétration des langues et des cultures par le biais de figures identitaires et esthétiques inédites, il y a lieu de s’interroger de plus près sur les pratiques scripturales qui lui sont propres. Dans cet article, nous nous proposons d’analyser la poétique de l’effaçonnement, soutènement de l’écriture de l’écrivain luxembourgeois d’origine italienne Jean Portante. Avec des textes choisis à l’appui, notamment des essais et le roman autofictionnel Mrs Haroy ou la mémoire de la baleine (1993), différents aspects de cette poétique seront examinés, à commencer par son rôle dans l’appréhension que ce poète-écrivain peut avoir de sa langue d’expression littéraire étrangère. Nous procédons ensuite à l’étude du roman autofictionnel pour la voir à l’œuvre dans la narrativisation de la mémoire dans le récit de soi. Les pratiques scripturales employées par Portante pour mettre en texte la mémoire interculturelle du migrant feront l’objet de notre conclusion. [less ▲]

The trace or the 0th Hochschild–Mitchell homology of a linear category C may be regarded as a kind of decategorification of C. We compute the traces of the two versions U˙ and U∗ of categorified quantum sl2 introduced by the third author. The trace of U is isomorphic to the split Grothendieck group K_0(U˙), and the higher Hochschild–Mitchell homology of U˙ is zero. The trace of U∗ is isomorphic to the idempotented integral form of the current algebra U(sl2[t]). [less ▲]

Our work aims to rationalize Enterprise Architectures (EA) by providing the reasoning behind the designs, in terms of selection criteria, design alternatives and more. Its major contribution is a formal metamodel that captures the reasoning and the inter-relationships of design decisions. This paper extends our approach in order to provide an explicit bridging between the Problem space that is defined by the different requirements and the Solution space that is described by specific design decisions. In doing so, EA Anamnesis also supports traceability from specific design decisions to the given requirements. [less ▲]

This chapter presents research conducted in early childhood classrooms in Luxembourg, a European country with a complex multilingual situation. A multi-layered corpus of classroom interactions, consisting of photos, videos and audio recordings, was collected over a period of 6 months and then classified, annotated and partially transcribed. Drawing from this corpus, this study sheds light on the discursive practices of 6-12 year old children and examines the co-construction of the children’s growing understandings of science in collaborative inquiries. Arguing from a context-sensitive perspective, our research approaches the learning of science as an interactional achievement in situ, one that encompasses the enactment of science as shared discourse and therefore as a cultural accomplishment.
