ASM catalyzes the breakdown of the abundant membrane lipid sphingomyelin to the lipid messenger ceramide. This ASM-induced lipid modification induces a local shift in membrane properties, which influences receptor clustering and downstream signaling. Canonical transient receptor potential channels 6 (TRPC6) are non-selective cation channels located in the cell membrane that play an important role in dendritic growth, synaptic plasticity and cognition in the brain. They can be activated by hyperforin, an ingredient of the herbal remedy St. John's wort for treatment of depression disorders. Because of their role in the context of major depression, we investigated the crosstalk between the ASM/ceramide system and TRPC6 ion channels in a pheochromocytoma cell line 12 neuronal cell model (PC12 rat pheochromocytoma cell line). Ca2+ imaging experiments indicated that hyperforin-induced Ca2+ influx through TRPC6 channels is modulated by ASM activity. While antidepressants, known as functional inhibitors of ASM activity, reduced TRPC6-mediated Ca2+ influx, extracellular application of bacterial sphingomyelinase rebalanced TRPC6 activity in a concentration-related way. This effect was confirmed in whole-cell patch clamp electrophysiology recordings. Lipidomic analyses revealed a decrease in very long chain ceramide/sphingomyelin molar ratio after ASM inhibition, which was connected with changes in the abundance of TRPC6 channels in flotillin-1-positive lipid rafts as visualized by western blotting. Our data provide evidence that the ASM/ceramide system regulates TRPC6 channels likely by controlling their recruitment to specific lipid subdomains and thereby fine-tuning their physical properties.}, language = {en} } @article{MientusWulffNowaketal.2023, author = {Mientus, Lukas and Wulff, Peter and Nowak, Anna and Borowski, Andreas}, title = {Algorithmen als Dozierende?}, series = {PSI-Potsdam: Ergebnisbericht zu den Aktivit{\"a}ten im Rahmen der Qualit{\"a}tsoffensive Lehrerbildung (2019-2023) (Potsdamer Beitr{\"a}ge zur Lehrerbildung und Bildungsforschung ; 3)}, journal = {PSI-Potsdam: Ergebnisbericht zu den Aktivit{\"a}ten im Rahmen der Qualit{\"a}tsoffensive Lehrerbildung (2019-2023) (Potsdamer Beitr{\"a}ge zur Lehrerbildung und Bildungsforschung ; 3)}, number = {3}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-568-2}, issn = {2626-3556}, doi = {10.25932/publishup-61640}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-616407}, pages = {117 -- 129}, year = {2023}, abstract = {Auf maschinellem Lernen basierende Tools haben schon l{\"a}ngst Einzug in unseren Alltag gefunden und so konnten auch in der Lehrkr{\"a}ftebildung erste Anwendungen entwickelt, erprobt und evaluiert werden.

More recently, open-ended, constructed response items were used to combine both approaches and advance assessment of complex science-related skills and competencies. For example, research in assessing science teachers' noticing and attention to classroom events benefitted from more open-ended response formats because teachers can present their own accounts. Then, open-ended responses are typically analyzed with some form of content analysis. However, language is noisy, ambiguous, and unsegmented and thus open-ended, constructed responses are complex to analyze. Uncovering patterns in these responses would benefit from more principled and systematic analysis tools. Consequently, computer-based methods with the help of machine learning and natural language processing were argued to be promising means to enhance assessment of noticing skills with constructed response formats. In particular, pretrained language models recently advanced the study of linguistic phenomena and thus could well advance assessment of complex constructs through constructed response items. This study examines potentials and challenges of a pretrained language model-based clustering approach to assess preservice physics teachers' attention to classroom events as elicited through open-ended written descriptions. It was examined to what extent the clustering approach could identify meaningful patterns in the constructed responses, and in what ways textual organization of the responses could be analyzed with the clusters. Preservice physics teachers (N = 75) were instructed to describe a standardized, video-recorded teaching situation in physics. The clustering approach was used to group related sentences. Results indicate that the pretrained language model-based clustering approach yields well-interpretable, specific, and robust clusters, which could be mapped to physics-specific and more general contents. Furthermore, the clusters facilitate advanced analysis of the textual organization of the constructed responses. Hence, we argue that machine learning and natural language processing provide science education researchers means to combine exploratory capabilities of qualitative research methods with the systematicity of quantitative methods.}, language = {en} } @article{WulffBuschhueterWestphaletal.2020, author = {Wulff, Peter and Buschh{\"u}ter, David and Westphal, Andrea and Nowak, Anna and Becker, Lisa and Robalino, Hugo and Stede, Manfred and Borowski, Andreas}, title = {Computer-based classification of preservice physics teachers' written reflections}, series = {Journal of science education and technology}, volume = {30}, journal = {Journal of science education and technology}, number = {1}, publisher = {Springer}, address = {Dordrecht}, issn = {1059-0145}, doi = {10.1007/s10956-020-09865-1}, pages = {1 -- 15}, year = {2020}, abstract = {Reflecting in written form on one's teaching enactments has been considered a facilitator for teachers' professional growth in university-based preservice teacher education. Writing a structured reflection can be facilitated through external feedback. However, researchers noted that feedback in preservice teacher education often relies on holistic, rather than more content-based, analytic feedback because educators oftentimes lack resources (e.g., time) to provide more analytic feedback. To overcome this impediment to feedback for written reflection, advances in computer technology can be of use. Hence, this study sought to utilize techniques of natural language processing and machine learning to train a computer-based classifier that classifies preservice physics teachers' written reflections on their teaching enactments in a German university teacher education program. To do so, a reflection model was adapted to physics education. It was then tested to what extent the computer-based classifier could accurately classify the elements of the reflection model in segments of preservice physics teachers' written reflections. Multinomial logistic regression using word count as a predictor was found to yield acceptable average human-computer agreement (F1-score on held-out test dataset of 0.56) so that it might fuel further development towards an automated feedback tool that supplements existing holistic feedback for written reflections with data-based, analytic feedback.}, language = {en} } @article{ActisAgnettaAharonianetal.2011, author = {Actis, M. and Agnetta, G. and Aharonian, Felix A. and Akhperjanian, A.

Direct effects of parental education on growth that were not transmitted via nutrition were shown in Indian datasets using network analysis and novel statistical methods (St. Nicolas House Analysis) that translate correlation matrices into network graphs. Data on Polish children suggest significant impact of socioeconomic sensitivity on child growth, with no effect of maternal money satisfaction. Height and maturation tempo affect the position of a child among its peers. Correlations also exist between mood disorders and height. Secular changes in height and weight varied across decades independent of population size. Historic and recent Russian data showed that height of persons whose fathers performed manual work were on average four cm shorter than persons whose fathers were high-degree specialists. Body height, menarcheal age, and body proportions are sensitive to socioeconomic variables.

CTA has ambitions science goals, for which it is necessary to achieve full-sky coverage, to improve the sensitivity by about an order of magnitude, to span about four decades of energy, from a few tens of GeV to above 100 TeV with enhanced angular and energy resolutions over existing VHE gamma-ray observatories. An international collaboration has formed with more than 1000 members from 27 countries in Europe, Asia, Africa and North and South America.

Die Auswertung von Unterrichtsreflexionen und eine entsprechende R{\"u}ckmeldung stellt Forschende und Dozierende allerdings vor praktische wie theoretische Herausforderungen. Im Kontext der Forschung zu K{\"u}nstlicher Intelligenz (KI) entwickelte Methoden bieten hier neue Potenziale. Der Beitrag stellt {\"u}berblicksartig zwei Teilstudien vor, die mit Hilfe von KI-Methoden wie dem maschinellen Lernen untersuchen, inwieweit eine Auswertung von Unterrichtsreflexionen angehender Physiklehrkr{\"a}fte auf Basis eines theoretisch abgeleiteten Reflexionsmodells und die automatisierte R{\"u}ckmeldung hierzu m{\"o}glich sind. Dabei wurden unterschiedliche Ans{\"a}tze des maschinellen Lernens verwendet, um modellbasierte Klassifikation und Exploration von Themen in Unterrichtsreflexionen umzusetzen. Die Genauigkeit der Ergebnisse wurde vor allem durch sog. Große Sprachmodelle gesteigert, die auch den Transfer auf andere Standorte und F{\"a}cher erm{\"o}glichen. F{\"u}r die fachdidaktische Forschung bedeuten sie jedoch wiederum neue Herausforderungen, wie etwa systematische Verzerrungen und Intransparenz von Entscheidungen. Dennoch empfehlen wir, die Potenziale der KI-basierten Methoden gr{\"u}ndlicher zu erforschen und konsequent in der Praxis (etwa in Form von Webanwendungen) zu implementieren.}, language = {de} } @book{AckermannAhlgrimmApelojgetal.2018, author = {Ackermann, Peter and Ahlgrimm, Frederik and Apelojg, Benjamin and B{\"o}rnert-Ringleb, Moritz and Borowski, Andreas and Ehlert, Antje and Eichler, Constanze and Frohn, Julia and Gehrmann, Marie-Luise and Gerlach, Erin and Goetz, Ilka and Goral, Johanna and Gronostaj, Anna and Grubert, Jana and G{\"u}lery{\"u}z, Burak and Hacke, Alexander and Heck, Sebastian and Hermanns, Jolanda and Hochmuth, J{\"o}rg and Jennek, Julia and Jostes, Brigitte and Jurczok, Anne and Kleemann, Katrin and Kortenkamp, Ulrich and Krauskopf, Karsten and K{\"u}choll, Denise and Kulawiak, Pawel R. and Lauterbach, Wolfgang and Lazarides, Rebecca and Linka, Tim and L{\"o}weke, Sebastian and Lohse-Bossenz, Hendrik and Maar, Verena and Nowak, Anna and Ratzlaff, Olaf and Reitz-Koncebovski, Karen and Rother, Stefanie and Scherreiks, Lynn and Schroeder, Christoph and Schwalbe, Anja and Schwill, Andreas and Tosch, Frank and Vock, Miriam and Wagner, Luisa and Westphal, Andrea and Wilbert, J{\"u}rgen}, title = {PSI-Potsdam}, series = {Potsdamer Beitr{\"a}ge zur Lehrerbildung und Bildungsforschung}, journal = {Potsdamer Beitr{\"a}ge zur Lehrerbildung und Bildungsforschung}, number = {1}, editor = {Borowski, Andreas and Ehlert, Antje and Prechtl, Helmut}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-442-5}, issn = {2626-3556}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-414542}, publisher = {Universit{\"a}t Potsdam}, pages = {354}, year = {2018}, abstract = {In Brandenburg kommt der Universit{\"a}t Potsdam eine besondere Rolle zu: Sie ist die einzige, an der zuk{\"u}nftige Lehrerinnen und Lehrer die erste Phase ihres Werdegangs - das Lehramtsstudium - absolvieren k{\"o}nnen. Vor diesem Hintergrund wurde bereits kurz nach der Gr{\"u}ndung im Jahr 1991 das „Potsdamer Modell der Lehrerbildung" entwickelt. Dieses Modell strebt fortlaufend eine enge Verzahnung von Theorie und Praxis {\"u}ber das gesamte Studium hinweg an und bindet hierf{\"u}r die schulpraktischen Studienanteile in besonderer Weise ein. Eine erneute St{\"a}rkung erfuhr die Lehrerbildung im Dezember 2014 mit der Gr{\"u}ndung des Zentrums f{\"u}r Lehrerbildung und Bildungsforschung (ZeLB). Aus der koordinierenden Arbeit des Zentrums entstand das fakult{\"a}ts{\"u}bergreifende Projekt „Professionalisierung - Schulpraktische Studien - Inklusion" (PSI-Potsdam) das im Rahmen der Qualit{\"a}tsoffensive Lehrerbildung des Bundesministeriums f{\"u}r Bildung und Forschung erfolgreich gef{\"o}rdert wurde (2015-2018) und dessen Verl{\"a}ngerung (2019-2023) bewilligt ist.

Algorithms and technologies in the domain of research related to artificial intelligence have been found to be useful in many tasks related to reflective writing analytics such as classification of text segments. However, mostly shallow learning algorithms have been employed so far. This study explores to what extent deep learning approaches can improve classification performance for segments of written reflections. To do so, a pretrained language model (BERT) was utilized to classify segments of preservice physics teachers' written reflections according to elements in a reflection-supporting model. Since BERT has been found to advance performance in many tasks, it was hypothesized to enhance classification performance for written reflections as well. We also compared the performance of BERT with other deep learning architectures and examined conditions for best performance. We found that BERT outperformed the other deep learning architectures and previously reported performances with shallow learning algorithms for classification of segments of reflective writing. BERT starts to outperform the other models when trained on about 20 to 30\% of the training data. Furthermore, attribution analyses for inputs yielded insights into important features for BERT's classification decisions. Our study indicates that pretrained language models such as BERT can boost performance for language-related tasks in educational contexts such as classification.}, language = {en} }
