@article{50008, abstract = {{While referencing is an important feature of academic writing, many students struggle with using sources. This struggle seems to be due, in part, to the tension students experience when advised to cite sources (i.e., others’ voices) on the one hand, and to demonstrate their own disciplinary voice on the other hand. The aim of this article is to contribute to the understanding of source use, presenting a figure that illustrates gradients of students’ engagement with sources in various sections of their bachelor’s theses. Based on Bakhtin’s idea that a writer’s voice gradually emerges out of others’ words, and the terms knowledge telling and knowledge transforming, we developed a continuum that might help to understand the complexity of source use. We arrived at this continuum through the qualitative exploration of students’ use of sources in 15 bachelor’s theses from the humanities in one Norwegian university. In this article, we illustrate the continuum through extracts from the students’ theses, showing how issues of voice are intertwined with students’ engagement with sources. We propose that understanding the various functions of sources as they are typically used in the disciplines will help students to develop and demonstrate their disciplinary voices. Moreover, the continuum provides a foundation for fruitful discussions of writing practices that raise critical awareness about implicit expectations concerning source use and issues of voice in academic writing.  }}, author = {{Stock, Ingrid and Karsten, Andrea and Eik-Nes, Nancy Lea}}, issn = {{1891-5108}}, journal = {{Sakprosa}}, keywords = {{Automotive Engineering}}, number = {{2}}, publisher = {{University of Oslo Library}}, title = {{{Emerging disciplinary voices}}}, doi = {{10.5617/sakprosa.10185}}, volume = {{15}}, year = {{2023}}, } @inproceedings{51218, abstract = {{Polymer composites represent the industry standard in injection molding for the production of plastic components with increased requirements in terms of heat resistance and stiffness.

Here, the resulting properties from two different powder production methods are compared. One filled powder is produced by dry blending and the other powder with the same filler and filling ratio is produced by encapsulating the filler particles inside the polymer particles within the dissolution-precipitation process. It was found that encapsulating the filler particles can provide certain benefits for the processability, for example an improved powder flowability or better filler dispersion. However, encapsulating the filler also alters the thermal properties of the precipitated powder. }}, author = {{Kletetzka, Ivo and Neitzel, Fabian and Schmid, Hans-Joachim}}, booktitle = {{Proceedings of the 34th Annual International Solid Freeform Fabrication Symposium}}, editor = {{Beaman, Joseph}}, keywords = {{Additive Manufacturing, Laser Sintering, Filled Materials, Composites, Polyamide 613}}, location = {{Austin}}, title = {{{Assessing the Impact of the Powder Production Method on Ceramic-filled Polyamide Composites made by Laser Sintering}}}, doi = {{https://doi.org/10.26153/tsw/50931}}, year = {{2023}}, } @inproceedings{46862, abstract = {{The high flammability of components manufactured by laser sintering (LS) using standard polyamide 12 (PA12) powder still severely restricts their use in industries such as electronics, aviation, and transportation.

We theoretically and experimentally reveal that when the structural symmetry of the meta-atom is incompatible with the lattice symmetry of an array, some generalized nonlinear geometric phases appear, which offers new possibilities for harmonic generation control beyond the accessible symmetries governed by the selection rule. The underlying mechanism is attributed to the modified rotation of the effective principal axis of a dense meta-atom array, where the strong coupling among the units gives rise to a generalized linear geometric phase modulation of the pump light. Therefore, nonlinear geometric phases carried by third-harmonic emissions are the natural result of the wave-mixing process among the modes excited at the fundamental frequency.

For two different downstream tasks, we use data reported to be gender biased and aggregate it with annotations. First, we propose a new approach to aspect-based sentiment analysis that allows identifying, extracting, and classifying implicit and explicit aspect phrases and their polarity within a single model. The second task we present is grade prediction, where we predict the overall grade of a review on the basis of the review text. For both tasks, we train numerous transformer models and evaluate their performance. The aggregation of sensitive attributes, such as a physician’s gender and migration background, with individual text reviews allows us to measure the performance of the models with respect to these sensitive groups. These group-wise performance measures act as extrinsic bias measures for our downstream tasks. In addition, we translate several gender-specific templates of the intrinsic bias metrics into the German language and evaluate our fine-tuned models. Based on this set of tasks, fine-tuned models, and intrinsic and extrinsic bias measures, we perform correlation analyses between intrinsic and extrinsic bias measures. In terms of sensitive groups and effect sizes, our bias measure results show different directions. Furthermore, correlations between measures of intrinsic and extrinsic bias can be observed in different directions. This leads us to conclude that gender-biased data does not inherently lead to biased models. Other variables, such as template dependency for intrinsic measures and label distribution in the data, must be taken into account as they strongly influence the metric results. Therefore, we suggest that metrics and templates should be chosen according to the given task and the biases to be assessed. }}, author = {{Kersting, Joschka and Maoro, Falk and Geierhos, Michaela}}, issn = {{0169-023X}}, journal = {{Data & Knowledge Engineering}}, keywords = {{Language model fairness, Aspect phrase classification, Grade prediction, Physician reviews}}, publisher = {{Elsevier}}, title = {{{Towards comparable ratings: Exploring bias in German physician reviews}}}, doi = {{10.1016/j.datak.2023.102235}}, volume = {{148}}, year = {{2023}}, } @inbook{45888, author = {{Wehrheim, Heike and Platzner, Marco and Bodden, Eric and Schubert, Philipp and Pauck, Felix and Jakobs, Marie-Christine}}, booktitle = {{On-The-Fly Computing -- Individualized IT-services in dynamic markets}}, editor = {{Haake, Claus-Jochen and Meyer auf der Heide, Friedhelm and Platzner, Marco and Wachsmuth, Henning and Wehrheim, Heike}}, pages = {{125--144}}, publisher = {{Heinz Nixdorf Institut, Universität Paderborn}}, title = {{{Verifying Software and Reconfigurable Hardware Services}}}, doi = {{10.5281/zenodo.8068583}}, volume = {{412}}, year = {{2023}}, } @inbook{45893, author = {{Hansmeier, Tim and Kenter, Tobias and Meyer, Marius and Riebler, Heinrich and Platzner, Marco and Plessl, Christian}}, booktitle = {{On-The-Fly Computing -- Individualized IT-services in dynamic markets}}, editor = {{Haake, Claus-Jochen and Meyer auf der Heide, Friedhelm and Platzner, Marco and Wachsmuth, Henning and Wehrheim, Heike}}, pages = {{165--182}}, publisher = {{Heinz Nixdorf Institut, Universität Paderborn}}, title = {{{Compute Centers I: Heterogeneous Execution Environments}}}, doi = {{10.5281/zenodo.8068642}}, volume = {{412}}, year = {{2023}}, } @inbook{45899, author = {{Boschmann, Alexander and Clausing, Lennart and Jentzsch, Felix and Ghasemzadeh Mohammadi, Hassan and Platzner, Marco}}, booktitle = {{On-The-Fly Computing -- Individualized IT-services in dynamic markets}}, editor = {{Haake, Claus-Jochen and Meyer auf der Heide, Friedhelm and Platzner, Marco and Wachsmuth, Henning and Wehrheim, Heike}}, pages = {{225--236}}, publisher = {{Heinz Nixdorf Institut, Universität Paderborn}}, title = {{{Flexible Industrial Analytics on Reconfigurable Systems-On-Chip}}}, doi = {{10.5281/zenodo.8068713}}, volume = {{412}}, year = {{2023}}, } @article{49306, author = {{Herdramm, Henrike}}, journal = {{BloKK.
