„Nesthäkchens Backfischzeit“ autorstwa ELSE URY a niemiecka rewolucja 1918/1919

Untersucht wird, wie der um 1920 erschienene fünfte Band der Nesthäkchen-Serie von ELSE URY typische Elemente des Backfischromans mit der Thematisierung der deutschen Revolution von 1918/1919 zu einer teils heterogenen, teils stimmigen Erzählung verbindet. Dazu wird das Konzept der Serie erläutert und als Teil der Modernisierung und Politisierung des Mädchenbuchs im späten Kaiserreich beschrieben. Die textnahe Lektüre konzentriert sich auf die bürgerliche Sicht der Revolution, den Klassenkonflikt und die Debatte um Schülerräte als den wichtigsten Aspekten dieses ‚Revolutionsromans für junge Mädchen‘.The fifth volume of ELSE URY’S Nesthäkchen series, published around 1920, combines typical elements of the “Backfischroman” (teenage girl novel) with motifs of the German Revolution of 1918/1919 and creates a partially heterogenic and partially homogenic narrative. In this context the idea behind the entire series is presented and the way in which the series became part of the process of modernization and politicization of books for girls in the late Empire is discussed. The analysis shows how the text focuses on the revolution, class conflict, and debates on student councils from a bourgeois perspective, foregrounding them as the most important aspects of the “revolutionary novel for young girls”.Przedmiotem artykułu jest zbadanie, w jaki sposób opublikowany około 1920 roku piąty tom serii Nesthäkchen ELSE URY łączy typowe elementy Backfischroman (powieści dla dorastających dziewcząt) z tematem rewolucji niemieckiej 1918/1919, tworząc częściowo heterogeniczną, częściowo jednolitą narrację. W tym kontekście przedstawiono koncepcję serii i pokazano, w jaki sposób wpisywała się ona w proces modernizacji i upolitycznienia książek dla dziewcząt u schyłku Cesarstwa Niemieckiego. Analiza samego tekstu skupia się na burżuazyjnym spojrzeniu na rewolucję, konflikcie klasowym i debacie wokół rad uczniowskich jako najważniejszych aspektach tej ,powieści rewolucyjnej dla młodych dziewcząt’

A new interaction force decomposition maximizing compensating forces under physical work constraints

Decomposition of interaction forces in manipulation tasks has a long research tradition. Interaction forces are often split into robustness-reflective and accelerating forces. While this decomposition is typically performed for the synthesis of interaction forces to be applied for example in the context of robotic grasping, less attention has been paid to the analysis of measured, human interaction forces. Here we present a new decomposition approach for interaction force analysis. It extends the intuitive solution known in literature for the two finger grasp and combines it with a physically motivated bounding constraint, which allows the maximization of robustness reflective forces. Advantages of our approach are illustrated with an example and are compared to existing decomposition approaches. In contrast to existing approaches the new approach is not limited in the number of interaction points and incorporates forces which are physically possible only

Towards Tracking Data Flows in Cloud Architectures

As cloud services become central in an increasing number of applications, they process and store more personal and business-critical data. At the same time, privacy and compliance regulations such as GDPR, the EU ePrivacy regulation, PCI, and the upcoming EU Cybersecurity Act raise the bar for secure processing and traceability of critical data. Especially the demand to provide information about existing data records of an individual and the ability to delete them on demand is central in privacy regulations. Common to these requirements is that cloud providers must be able to track data as it flows across the different services to ensure that it never moves outside of the legitimate realm, and it is known at all times where a specific copy of a record that belongs to a specific individual or business process is located. However, current cloud architectures do neither provide the means to holistically track data flows across different services nor to enforce policies on data flows. In this paper, we point out the deficits in the data flow tracking functionalities of major cloud providers by means of a set of practical experiments. We then generalize from these experiments introducing a generic architecture that aims at solving the problem of cloud-wide data flow tracking and show how it can be built in a Kubernetes-based prototype implementation.Comment: 11 pages, 5 figures, 2020 IEEE 13th International Conference on Cloud Computing (CLOUD

Poster: Patient Community -- A Test Bed For Privacy Threat Analysis

Research and development of privacy analysis tools currently suffers from a lack of test beds for evaluation and comparison of such tools. In this work, we propose a benchmark application that implements an extensive list of privacy weaknesses based on the LINDDUN methodology. It represents a social network for patients whose architecture has first been described in an example analysis conducted by one of the LINDDUN authors. We have implemented this architecture and extended it with more privacy threats to build a test bed that enables comprehensive and independent testing of analysis tools.Comment: 3 pages, 1 figur

Experiment Preparation and Performance for the Electromagnetic Levitator (EML) Onboard the International Space Station

The electromagnetic levitation (EML) facility on board the ISS is a powerful tool for investigation of solidification phenomena of metallic melts and precise measurement of thermophysical properties of the liquid. Containerless processing enables deep undercoolings prior to solidification and the analysis of crystal nucleation and growth phenomena. The microgravity environment allows studying these processes under reduced fluid flow and moreover under different levels of melt convection by systematic variation of electromagnetic stirring. Material properties like density, specific heat, surface tension, viscosity, thermal and electrical conductivity of liquid metals and semiconductors are determined in the absence of disturbances caused by container walls and gravity forces. Scientists are supported by facility and mission specialists for preparation and performance, which is decisive for successful operation on orbit. User support comprises the determination of material data, development of experiment procedure, parameter sets and their validation in the ground model as well as the conduction of space experiments by real-time monitoring and control. The comprehensive support program for the entire life cycle of science project from experiment definition to its operation ensures high-quality data and an optimum of scientific results

Acidic Environment Leads to ROS-Induced MAPK Signaling in Cancer Cells

Tumor micromilieu often shows pronounced acidosis forcing cells to adapt their phenotype towards enhanced tumorigenesis induced by altered cellular signalling and transcriptional regulation. In the presents study mechanisms and potential consequences of the crosstalk between extra- and intracellular pH (pHe, pHi) and mitogen-activated-protein-kinases (ERK1/2, p38) was analyzed. Data were obtained mainly in AT1 R-3327 prostate carcinoma cells, but the principle importance was confirmed in 5 other cell types. Extracellular acidosis leads to a rapid and sustained decrease of pHi in parallel to p38 phosphorylation in all cell types and to ERK1/2 phosphorylation in 3 of 6 cell types. Furthermore, p38 phosphorylation was elicited by sole intracellular lactacidosis at normal pHe. Inhibition of ERK1/2 phosphorylation during acidosis led to necrotic cell death. No evidence for the involvement of the kinases c-SRC, PKC, PKA, PI3K or EGFR nor changes in cell volume in acidosis-induced MAPK activation was obtained. However, our data reveal that acidosis enhances the formation of reactive oxygen species (ROS), probably originating from mitochondria, which subsequently trigger MAPK phosphorylation. Scavenging of ROS prevented acidosis-induced MAPK phosphorylation whereas addition of H2O2 enhanced it. Finally, acidosis increased phosphorylation of the transcription factor CREB via p38, leading to increased transcriptional activity of a CRE-reporter even 24 h after switching the cells back to a normal environmental milieu. Thus, an acidic tumor microenvironment can induce a longer lasting p38-CREB-medited change in the transcriptional program, which may maintain the altered phenotype even when the cells leave the tumor environment
