To this end, we investigate the narratives of Canadian learners, studying abroad in Germany, in relation to discourses of language learning, culture, and identity, using a Critical Discourse Analysis approach. Our data, which we gained from semi-structured interviews and e-journals, shows that learners’ perceptions of pronunciation are closely linked to their views of the native-speaker ideal, impacting their self-constructions and interpretations of learning experience.

In an age of smart products and smart data, we can, however, expect that many of future service innovations need to be based on adding, transferring, dissociating, and associating existing value propositions. The purpose of this paper is to outline what properties constitute recombinant service innovation and to identify if current service engineering approaches fulfill these properties. Based on a conceptual in-depth analysis of 24 service engineering methods, we identify that most methods focus on designing value propositions instead of service systems, view service independent of physical goods, are linear or iterative, and incompletely address the mechanisms of recombinant innovation. We discuss how these deficiencies can be remedied and propose a first conceptual model of a revised se rvice system engineering approach.}}, author = {{Beverungen, Daniel and Lüttenberg, Hedda and Wolf, Verena}}, booktitle = {{Proceedings der 13.

This work is focused on epistemic uncertainties in the framework of continuum mechanics, which are taken into account by fuzzy analysis. The underlying min-max optimization problem of the extension principle is approximated by α-discretization, resulting in a separation of minimum and maximum problems. To become more universal, so-called quantities of interest are employed, which allow a general formulation for the target problem of interest. In this way, the relation to parameter identification problems based on least-squares functions is highlighted. The solutions of the related optimization problems with simple constraints are obtained with a gradient-based scheme, which is derived from a sensitvity analysis for the target problem by means of a variational formulation. Two numerical examples for the fuzzy analysis of material parameters are concerned with a necking problem at large strain elastoplasticity and a perforated strip at large strain hyperelasticity to demonstrate the versatility of the proposed variational formulation. }}, author = {{Mahnken, Rolf}}, issn = {{ 2325-3444}}, journal = {{Mathematics and Mechanics of complex systems}}, keywords = {{fuzzy analysis, α-level optimization, quantities of interest, optimization with simple constraints, large strain elasticity, large strain elastoplasticity}}, number = {{3-4}}, title = {{{"A variational formulation for fuzzy analysis in continuum mechanics"}}}, volume = {{5}}, year = {{2017}}, } @article{45946, author = {{Kovács, Balázs and Power Guerra, Christian Andreas}}, issn = {{0749-159X}}, journal = {{Numerical Methods for Partial Differential Equations}}, keywords = {{Applied Mathematics, Computational Mathematics, Numerical Analysis, Analysis}}, number = {{2}}, pages = {{518--554}}, publisher = {{Wiley}}, title = {{{Maximum norm stability and error estimates for the evolving surface finite element method}}}, doi = {{10.1002/num.22212}}, volume = {{34}}, year = {{2017}}, } @article{45945, author = {{Kovács, Balázs and Power Guerra, Christian Andreas}}, issn = {{0749-159X}}, journal = {{Numerical Methods for Partial Differential Equations}}, keywords = {{Applied Mathematics, Computational Mathematics, Numerical Analysis, Analysis}}, number = {{2}}, pages = {{518--554}}, publisher = {{Wiley}}, title = {{{Maximum norm stability and error estimates for the evolving surface finite element method}}}, doi = {{10.1002/num.22212}}, volume = {{34}}, year = {{2017}}, } @article{32020, author = {{Küster, Benjamin}}, issn = {{0232-704X}}, journal = {{Annals of Global Analysis and Geometry}}, keywords = {{Geometry and Topology, Analysis}}, number = {{1}}, pages = {{57--97}}, publisher = {{Springer Science and Business Media LLC}}, title = {{{On the semiclassical functional calculus for h-dependent functions}}}, doi = {{10.1007/s10455-017-9549-1}}, volume = {{52}}, year = {{2017}}, } @article{32022, author = {{Küster, Benjamin and Ramacher, Pablo}}, issn = {{0022-1236}}, journal = {{Journal of Functional Analysis}}, keywords = {{Analysis}}, number = {{1}}, pages = {{41--124}}, publisher = {{Elsevier BV}}, title = {{{Quantum ergodicity and symmetry reduction}}}, doi = {{10.1016/j.jfa.2017.02.013}}, volume = {{273}}, year = {{2017}}, } @inbook{48411, author = {{Wessel, Lena}}, booktitle = {{Proceedings of the Tenth Congress of the European Society for Research in Mathematics Education (CERME10, February 1 – 5, 2017)}}, editor = {{Dooley, T. and Gueudet, G.}}, keywords = {{Academic language, relative frequency, scaffolding, design research, trace analysis}}, pages = {{1388--1395}}, publisher = {{DCU Institute of Education and ERME.}}, title = {{{How do students develop lexical means for understanding the concept of relative frequency?
