Targeting for rare observables, the CBM experiment will operate at high interaction rates of up to 10 MHz, which is unprecedented in heavy-ion experiments so far. It requires a novel free-streaming readout system and a new concept of data processing. The huge data rates of the CBM experiment will be reduced online to the recordable rate before saving the data to the mass storage. Full collision reconstruction and selection will be performed online in a dedicated processor farm. In order to make an efficient event selection online a clean sample of particles has to be provided by the reconstruction package called First Level Event Selection (FLES).
The FLES reconstruction and selection package consists of several modules: track finding, track fitting, event building, short-lived particles finding, and event selection. Since detector measurements contain also time information, the event building is done at all stages of the reconstruction process. The input data are distributed within the FLES farm in a form of time-slices. A time-slice is reconstructed in parallel between processor cores. After all tracks of the whole time-slice are found and fitted, they are collected into clusters of tracks originated from common primary vertices, which then are fitted, thus identifying the interaction points. Secondary tracks are associated with primary vertices according to their estimated production time. After that short-lived particles are found and the full event building process is finished. The last stage of the FLES package is a selection of events according to the requested trigger signatures. The event reconstruction procedure and the results of its application to simulated collisions in the CBM detector setup are presented and discussed in detail.
The standard implementation of the HRG model has been shown to be unable to describe all the available data on QCD matter. Here we show the balance of repulsive and attractive hadronic interactions on QCD thermodynamics through observables both calculated by lattice simulations and measured in experiment. Attractive interactions are mediated by resonance formation, which are here implemented through extra states predicted by the Quark Model, while repulsive interactions are modelled by means of Excluded Volume (EV) effects. Informations on flavour dependent effective sizes are extracted. It is found that EV effects are present in lattice QCD thermodynamics, and are essential for a comprehensive description of higher order fluctuations of conserved charges.
Die Tagung rief dazu auf, die Verbindlichkeit von Versprechen als allgemeines Phänomen zu untersuchen, also zu ergründen, inwiefern man unabhängig von ihrer Ausgestaltung in konkreten Rechtsordnungen oder anderen Normensystemen von einer "vor-rechtlichen" Verbindlichkeit sprechen kann. Literarische Texte aller Zeiten bis hin zu den Mythen bezeugen die Bindung an das Wort als Urerfahrung, die von jeder gesellschaftlichen Konvention unabhängig erscheint. Ebenso kennen sie aber Verrat und offenen oder verdeckten Wortbruch, deren Folgen sie thematisieren. Strukturelle Verwandtschaften einerseits und gegenseitige Beeinflussung andererseits der literarischen und der rechtlichen Auseinandersetzung mit dem Versprechen sollten untersucht werden.
We show the first results for parton distribution functions within the proton at the physical pion mass, employing the method of quasi-distributions. In particular, we present the matrix elements for the iso-vector combination of the unpolarized, helicity and transversity quasi-distributions, obtained with Nf = 2 twisted mass cloverimproved fermions and a proton boosted with momentum = 0.83 GeV. The momentum smearing technique has been applied to improve the overlap with the proton boosted state. Moreover, we present the renormalized helicity matrix elements in the RI’ scheme, following the non-perturbative renormalization prescription recently developed by our group.
We discuss the current developments by the European Twisted Mass Collaboration in extracting parton distribution functions from the quasi-PDF approach. We concentrate on the non-perturbative renormalization prescription recently developed by us, using the RI′ scheme. We show results for the renormalization functions of matrix elements needed for the computation of quasi-PDFs, including the conversion to the MS scheme, and for renormalized matrix elements. We discuss the systematic effects present in the Z-factors and the possible ways of addressing them in the future.
Challenges of FAIR phase 0
(2018)
After two-year's shutdown, the GSI accelerators plus the latest addition of storage ring CRYRING, will be back into operation in 2018 as the FAIR phase 0 with the goal to fulfill the needs of scientific community and the FAIR accelerators and detector development. Even though GSI has been well known for its operation of a variety of ion beams ranging from proton up to uranium for multi research areas such as nuclear physics, astrophysics, biophysics, material science, the upcoming beam time faces a number of challenges in re-commissioning its existing circular accelerators with brand new control system and upgrade of beam instrumentations, as well as in rising failures of dated components and systems. The cycling synchrotron SIS18 has been undergoing a set of upgrade measures for fulfilling future FAIR operation, among which many measures will also be commissioned during the upcoming beam time. This paper presents the highlights of the challenges such as re-establishing the high intensity heavy ion operation as well as parallel operation mode for serving multi users. The status of preparation including commissioning results will also be reported.
Delayed-onset muscle soreness (DOMS) is a common symptom in people participating in exercise, sport, or recreational physical activities. Several remedies have been proposed to prevent and alleviate DOMS. In 2008 and 2015, two studies have been conducted to investigate the effects of acupuncture on symptoms and muscle function in eccentric exercise-induced DOMS of the biceps brachii muscle. In 2008 a prospective, randomized, controlled, observer and subject-blinded trial was undertaken with 22 healthy subjects (22–30 years; 12 females) being randomly assigned to three treatment groups: real acupuncture (deep needling at classic acupuncture points and tender points; n = 7), sham-acupuncture (superficial needling at non-acupuncture points; n = 8), and control (n = 7). In 2015, a five-arm randomized controlled study was conducted with 60 subjects (22 females, 23.6 ± 2.8 years). Participants were randomly allocated to needle, laser, sham needle, sham laser acupuncture, and no intervention.
In both cases treatment was applied immediately, 24 and 48 hours after DOMS induction.
The outcome measures included pain perception (visual analogue scale; VAS), mechanical pain threshold (MPT), maximum isometric voluntary force (MIVF) and pressure pain threshold (PPT).
Results: In 2008, following nonparametric testing, there were no significant differences between groups in outcome measures at baseline. After 72 hours, pain perception (VAS) was significantly lower in the acupuncture group compared to the sham acupuncture and control subjects. However, the mean MPT and MIVF scores were not significantly different between groups. This lead to the conclusion, that acupuncture seemed to have no effects on MPT and muscle function, but reduced perceived pain arising from exercise-induced DOMS.
The more recent results from 2015 indicated that neither verum nor sham interventions significantly improved outcomes within 72 hours when compared with the no treatment control (P > 0.05).
This paper traces the military role of Tibnīn and its rulers in the Latin East against the Muslims until 1187/ 583. Tibnīn played a key role in overcoming the Muslims in Tyre and controlled it in 1124. It also played a vital role in the conflict between Damascus and the Kingdom of Jerusalem. Tibnīn participated in defending Antioch, Banyas, Hebron and Transjordan several times. Furthermore, its soldiers and Knights joined the army of the Kingdom of Jerusalem to capture Ascalon in 1153, and joined the campaigns of Amaury I, King of Jerusalem, against Egypt from 1164 to1169. The military situation of Tibnīn under the rule of the royal house until its fall to the Muslims in 1187/ 583 will be studied as well
We study tetraquark resonances with lattice QCD potentials computed for two static quarks and two dynamical quarks, the Born-Oppenheimer approximation and the emergent wave method of scattering theory. As a proof of concept we focus on systems with isospin I = 0, but consider different relative angular momenta l of the heavy b quarks. We compute the phase shifts and search for S and T matrix poles in the second Riemann sheet. We predict a new tetraquark resonance for l = 1, decaying into two B mesons, with quantum numbers I(JP) = 0(1−), mass MeV and decay width MeV.
We investigate the properties of QCD at finite isospin chemical potential at zero and non-zero temperatures. This theory is not affected by the sign problem and can be simulated using Monte-Carlo techniques. With increasing isospin chemical potential and temperatures below the deconfinement transition the system changes into a phase where charged pions condense, accompanied by an accumulation of low modes of the Dirac operator. The simulations are enabled by the introduction of a pionic source into the action, acting as an infrared regulator for the theory, and physical results are obtained by removing the regulator via an extrapolation. We present an update of our study concerning the associated phase diagram using 2+1 flavours of staggered fermions with physical quark masses and the comparison to Taylor expansion. We also present first results for our determination of the equation of state at finite isospin chemical potential and give an example for a cosmological application. The results can also be used to gain information about QCD at small baryon chemical potentials using reweighting with respect to the pionic source parameter and the chemical potential and we present first steps in this direction.
We will discuss the issue of Landau levels of quarks in lattice QCD in an external magnetic field. We will show that in the two-dimensional case the lowest Landau level can be identified unambiguously even if the strong interactions are turned on. Starting from this observation, we will then show how one can define a “plowest Landau level” in the four-dimensional case, and discuss how much of the observed effects of a magnetic field can be explained in terms of it. Our results can be used to test the validity of low-energy models of QCD that make use of the lowest-Landau-level approximation.
n this contribution we lay down a lattice setup that allows for the nonperturbative study of a field theoretical model where a SU(2) fermion doublet, subjected to non-Abelian gauge interactions, is also coupled to a complex scalar field doublet via a Yukawa and an “irrelevant” Wilson-like term. Using naive fermions in quenched approximation and based on the renormalizedWard identities induced by purely fermionic chiral transformations, lattice observables are discussed that enable: a) in theWigner phase, the determinations of the critical Yukawa coupling value where the purely fermionic chiral transformation become a symmetry up to lattice artifacts; b) in the Nambu-Goldstone phase of the resulting critical theory, a stringent test of the actual generation of a fermion mass term of non-perturbative origin. A soft twisted fermion mass term is introduced to circumvent the problem of exceptional configurations, and observables are then calculated in the limit of vanishing twisted mass.
A full session was organized in memory of Helmut Oeschler during the 2017 edition of the Strangeness in Quark Matter Conference. It was heart-warming to discuss with the audience his main achievements and share anecdotes about this exceptionally praised and appreciated colleague, who was also a great friend for many at the conference. A brief summary of the session is provided with these proceedings.
We report on the status of ongoing investigations aiming at locating the deconfinement critical point with standard Wilson fermions and Nf = 2 flavors towards the continuum limit (standard Columbia plot); locating the tricritical masses at imaginary chemical potential with unimproved staggered fermions at Nf = 2 (extended Columbia plot); identifying the order of the chiral phase transition at μ = 0 for Nf = 2 via extrapolation from non integer Nf (alternative Columbia plot).
An automated beam-setting optimization application has been implemented on top of FAIR’s control system software stack based on CERN’s LSA framework. The optimization functionality is built using the Jenetics software library implemented in Java. Tests of the software with beam have been performed at the CRYRING@ESR ion storage ring.
We study the properties of the survival probability of an unstable quantum state described by a Lee Hamiltonian. This theoretical approach resembles closely Quantum Field Theory (QFT): one can introduce in a rather simple framework the concept of propagator and Feynman rules, Within this context, we re-derive (in a detailed and didactical way) the well-known result according to which the amplitude of the survival probability is the Fourier transform of the energy distribution (or spectral function) of the unstable state (in turn, the energy distribution is proportional to the imaginary part of the propagator of the unstable state). Typically, the survival probability amplitude is the starting point of many studies of non-exponential decays. This work represents a further step toward the evaluation of the survival probability amplitude in genuine relativistic QFT. However, although many similarities exist, QFT presents some differences w.r.t. the Lee Hamiltonian which should be studied in the future.
Observations of long rang azimuthal correlations in small collision systems (p+p/A) have triggered an enormous excitement in the heavy-ion community. However, it is presently unclear to what extent the experimentally observed correlations should be attributed to initial state momentum correlations and/or the final state response to the initial state geometry. We discuss how a consistent theoretical description of the nonequilibrium dynamics is important to address both effects within a unified framework and present first results from weakly coupled non-equilibrium simulations in [1] to quantify the relative importance of initial state and final state effects based on theoretical calculations.
Augmented reality (AR) gained much public attention since the success of Pok´emon Go in 2016. Technology companies like Apple or Google are currently focusing primarily on mobile AR (MAR) technologies, i.e. applications on mobile devices, like smartphones or tablets. Associated privacy issues have to be investigated early to foster market adoption. This is especially relevant since past research found several threats associated with the use of smartphone applications. Thus, we investigate two of the main privacy risks for MAR application users based on a sample of 19 of the most downloaded MAR applications for Android. First, we assess threats arising from bad privacy policies based on a machine-learning approach. Second, we investigate which smartphone data resources are accessed by the MAR applications. Third, we combine both approaches to evaluate whether privacy policies cover certain data accesses or not. We provide theoretical and practical implications and recommendations based on our results.
We investigate privacy concerns and the privacy behavior of users of the AR smartphone game Pokémon Go. Pokémon Go accesses several functionalities of the smartphone and, in turn, collects a plethora of data of its users. For assessing the privacy concerns, we conduct an online study in Germany with 683 users of the game. The results indicate that the majority of the active players are concerned about the privacy practices of companies. This result hints towards the existence of a cognitive dissonance, i.e. the privacy paradox. Since this result is common in the privacy literature, we complement the first study with a second one with 199 users, which aims to assess the behavior of users with regard to which measures they undertake for protecting their privacy. The results are highly mixed and dependent on the measure, i.e. relatively many participants use privacy-preserving measures when interacting with their smartphone. This implies that many users know about risks and might take actions to protect their privacy, but deliberately trade-off their information privacy for the utility generated by playing the game.
Professor Walter Greiner, our mentor, colleague, and friend, passed away in the age of eighty. During his lifetime, the search for elements beyond uranium started and elements up to the so far heaviest one with atomic number 118 were discovered. In this talk I will present a short history from early searches for ‘trans-uraniums’ up to the production and safe identification of shell-stabilized ‘Super-Heavy Nuclei’ (SHN). The nuclear shell model reveals that these nuclei should be located in a region with closed shells for the protons at Z = 114, 120 or 126 and for the neutrons at N = 184. The outstanding aim of experimental investigations is the exploration of this region of spherical SHN. Systematic studies of heavy ion reactions for the synthesis of SHN revealed production cross-sections which reached values down to one picobarn and even below for the heaviest species. The systematics of measured cross-sections can be understood only on the basis of relatively high fission barriers as predicted for nuclei in and around the island of SHN. A key role in answering some of the open questions plays the synthesis of isotopes of element 120. Attempts aiming for synthesizing this element at the velocity filter SHIP will be reported.
Introduction: Ferroptosis has recently been identified as a form of programmed cell death caused by an accumulation of lipid reactive oxygen species (ROS). However, little is yet known about the role in hepatocellular carcinoma (HCC) and its signalling mechanism as well the modulation of ROS.
Material and methods: Human HCC cell lines were treated with different concentrations of ROS modulators (Auranofin, Erastin, BSO). Cell death was determined by analysis of PI-stained nuclei using flow cytometry. ROS production and lipid peroxidation were analysed at early time points before cell death starts. For mechanistic studies we performed Western Blot and a Proteome array. Different inhibitors of cell death target proteins, ROS-scavengers as well as lipoxygenase inhibitors were used. To investigate the functional relevance of NAPDH oxidases (NOX) 1 and 4 for ROS modulation and ferroptosis we genetically silenced its genes using three distinct siRNAs and we used the NOX1/4-inhibitor GKT137831.
Results and discussions: Compared to the single treatment, Auranofin/BSO-cotreatment as well as Erastin/BSO-cotreatment acted in concert to trigger cell death and to reduce cell viability of HCC cells in a dose- and time-dependent manner. Furthermore, both cotreatments induce ROS production, lipid peroxidation and ferroptotic cell death, which could be inhibited by the use of Ferrostatin-1 (inhibitor of lipid peroxidation) and Liproxstatin-1 (specific inhibitor of ferroptosis). The broad-range caspase inhibitor zVAD.fmk failed to rescue cells from Auranofin/BSO- or Erastin/BSO-cotreatment induced cell death. No activation of caspases-3 could be seen in the proteome profiler apoptosis assay. Importantly, the selective lipoxygenase (LOX) inhibitor Baicalain and the pan-LOX inhibitor NDGA protect HCC cells from Auranofin/BSO- and Erastin/BSO-cotreatment stimulated lipid peroxidation, ROS generation and cell death, indication that the induction of ferroptosis may bypass apoptosis resistance of HCC cells. Mechanistic studies showed that Auranofin/BSO-cotreatment decreased TrxR-activity, led to Nrf2 accumulation and promoted the activation of HO-1. In contrast, NOX 1 and 4 were involved in Erastin/BSO-mediated cell death and the use of the NOX1/4-inhibitor GKT137831 rescued HCC cells from the Erastin/BSO-induced cell death.
Conclusion: By providing new insights into the molecular regulation of ROS and ferroptosis, our study contributes to the development of novel treatment strategies to reactivate programmed cell death in HCC cells.
Im Zeitraum vom 7. bis zum 9. Dezember 2017 fand an der Universität Breslau (Wrocław) in Kooperation mit der Ruhr-Universität Bochum die Winterschool "Europa: Poetik und Politik" statt. Die gut zwanzig Teilnehmerinnen und Teilnehmer – darunter Professor*innen, wissenschaftliche Mitarbeiter*innen und Studierende beider Universitäten – diskutierten die neuere Geschichte von Europa-Diskursen von der Romantik bis in die Gegenwart. Ausgangspunkt der Tagung war die gegenwärtige Krise der Europäischen Union, die – so zeigte sich im Verlauf der Tagung – als Fortführung der leitmotivischen 'Schwellensituationen' zu verstehen ist, die als das Gemeinsame der diskutierten Texte und somit in gewisser Weise als konstitutiv für den Europa-Diskurs erkannt wurden.
This paper provides an assessment framework for privacy policies of Internet of Things Services which is based on particular GDPR requirements. The objective of the framework is to serve as supportive tool for users to take privacy-related informed decisions. For example when buying a new fitness tracker, users could compare different models in respect to privacy friendliness or more particular aspects of the framework such as if data is given to a third party. The framework consists of 16 parameters with one to four yes-or-no-questions each and allows the users to bring in their own weights for the different parameters. We assessed 110 devices which had 94 different policies. Furthermore, we did a legal assessment for the parameters to deal with the case that there is no statement at all regarding a certain parameter. The results of this comparative study show that most of the examined privacy policies of IoT devices/services are insufficient to address particular GDPR requirements and beyond. We also found a correlation between the length of the policy and the privacy transparency score, respectively.
Von der Gruppenarbeit zum Community Building - der "Digital Creative Space" der SUB Göttingen
(2018)
Die Förderung der digitalen Kompetenzen von Studierenden und die Entwicklung adaptiver, interaktiver und multimedialer (digitaler), diversitätsorientierter Lernumgebungen sind Schwerpunkte der Digitalen Hochschulbildung. Dies hat auch erheblichen Einfluss auf die konzeptionelle Planung und Gestaltung von physischen Lernraumangeboten wissenschaftlicher Bibliotheken. Ein deutliches Desiderat ist dabei die Bereitstellung niedrigschwelliger, kollaborativ nutzbarer Lernumgebungen, in denen Studierende (und auch Lehrende) gemeinsam digitale Kenntnisse erwerben, explorativ erproben und stärken können, um den Anforderungen sowohl im Studium als auch im späteren Berufsleben gerecht werden zu können. Gemeinsam mit dem Service für Digitales Lernen und Lehren und der Abteilung IT der Universität Göttingen hat die Benutzungsabteilung der SUB Göttingen ein Raumkonzept für ein "Digital Creative Space" erarbeitet, das in gemeinsamen Workshops mit Studierenden und Lehrenden des Göttinger Campus weiterentwickelt wurde. Sein Start in der hochfrequentierten Zentralbibliothek ist für 2018 geplant. Das Ergebnis dieses Prozesses ist eine Bündelung interdisziplinärer Labs verschiedenster technischer Ausstattung und interdisziplinärer Gruppenarbeit - das "Digital Creative Space". Ziel ist, den Nutzenden das eigenständige Entwickeln digitaler Kompetenzen zu ermöglichen und kreative Prozesse zu unterstützen - und dabei "communities of practice" zu initiieren oder zu befördern. Das Konzept, seine Entwicklungs- und weiteren Umsetzungsschritte einschließlich der Darstellung des partizipativen Prozesses sind Inhalt dieses Vortrags.
We compute hybrid static potentials in SU(3) lattice gauge theory. We present a method to automatically generate a large set of suitable creation operators with defined quantum numbers from elementary building blocks. We show preliminary results for several channels and discuss, which structures of the gluonic flux tube seem to be realized by the ground states in these channels.
Einstein’s theory of general relativity is often regarded as the best theory of gravity that we know. Yet, this theory often manifests itself under conditions where no symmetry is present and nonlinear dynamics dominates. I will discuss how these conditions are systematically accompanied by the restoration of some degree of symmetry. Hence, despite gravity appearing often under conditions devoid of symmetry, asymptotic solutions tend to restore symmetry.
A 3d regional density-driven flow model of a heterogeneous aquifer system at the German North Sea Coast is set up within the joint project NAWAK (“Development of sustainable adaption strategies for the water supply and distribution infrastructure on condition of climatic and demographic change”). The development of the freshwater-saltwater interface is simulated for three climate and demographic scenarios.
Groundwater flow simulations are performed with the finite volume code d3f++ (distributed density driven flow) that has been developed with a view to the modelling of large, complex, strongly density-influenced aquifer systems over long time periods.
The High-Acceptance DiElectron Spectrometer (HADES) operates in the 1 - 2A GeV energy regime in fixed target experiments to explore baryon-rich strongly interacting matter in heavy-ion collisions at moderate temperatures with rare and penetrating probes. We present results on the production of strange hadrons below their respective NN threshold energy in Au+Au collisions at 1.23A GeV ( = 2.4 GeV). Special emphasis is put on the enhanced feed-down contribution of ϕ mesons to the inclusive yield of K- and its implication on the measured spectral shape of K-. Furthermore, we investigate global properties of the system, confronting the measured hadron yields and transverse mass spectra with a Statistical Hadronization Model (SHM) and a blastwave parameterization, respectively. These supplement the world data of the chemical and kinetic freeze-out temperatures.
This lecture is about the history of the "Naier idisher teater" in Riga, the construction process of the building since 1913, the people and organisations that were involved, the theatre opening, playing schedules, companies, cooperation and actors as well as about the intercultural, economic and social environments and activities around the theatre until it was closed forcibly by the German troupes in 1941.
In this talk we discuss the effects of the hadronic rescattering on final state observables in high energy nuclear collisions. We do so by employing the UrQMD transport model for a realistic description of the hadronic decoupling process. The rescattering of hadrons modifies every hadronic bulk observable. For example apparent multiplicity of resonances is suppressed as compared to a chemical equilibrium freeze-out model. Stable and unstable particles change their momentum distribution by more than 30% through rescattering. The hadronic rescattering also leads to a substantial decorrelation of the conserved charge distributions. These findings show that it is all but trivial to conclude from the final state observables on the properties of the system at an earlier time where it may have been in or close to local equilibrium.
We describe two independent frameworks which provide unambiguous determinations of the deconfinement and the decoupling conditions of a relativistic gas at finite temperature. First, we use the Polyakov-Nambu-Jona–Lasinio model to compute meson and baryon masses at finite temperature and determine their melting temperature as a function of their strangeness content. Second, we analyze a simple expanding gas within a Friedmann-Robertson-Walker metric, which admits a well-defined decoupling mechanism. We examine the decoupling time as a function of the particle mass and cross section. We find evidences of an inherent dependence of the hadronization and freeze-out conditions on flavor, and on mass and cross section, respectively.
With the ongoing loss of global biodiversity, long-term recordings of species distribution patterns are increasingly becoming important to investigate the causes and consequences for their change. Therefore, the digitization of scientific literature, both modern and historical, has been attracting growing attention in recent years. To meet this growing demand the Specialised Information Service for Biodiversity Research (BIOfid) was launched in 2017 with the aim of increasing the availability and accessibility of biodiversity information. Closely tied to the research community the interdisciplinary BIOfid team is digitizing data sources of biodiversity related research and provides a modern and professional infrastructure for hosting and sharing them. As a pilot project, German publications on the distribution and ecology of vascular plants, birds, moths and butterflies covering the past 250 years are prioritized. Large parts of the text corpus defined in accordance with the needs of the relevant German research community have already been transferred to a machine-readable format and will be publicly accessible soon. Software tools for text mining, semantic annotation and analysis with respect to the current trends in machine learning are developed to maximize bioscientific data output through user-specific queries that can be created via the BIOfid web portal (https://www.biofid.de/). To boost knowledge discovery, specific ontologies focusing on morphological traits and taxonomy are being prepared and will continuously be extended to keep up with an ever-expanding volume of literature sources.
In this proceeding we review our recent work using supervised learning with a deep convolutional neural network (CNN) to identify the QCD equation of state (EoS) employed in hydrodynamic modeling of heavy-ion collisions given only final-state particle spectra ρ(pT, Ф). We showed that there is a traceable encoder of the dynamical information from phase structure (EoS) that survives the evolution and exists in the final snapshot, which enables the trained CNN to act as an effective “EoS-meter” in detecting the nature of the QCD transition.

Welches Wissen schafft Praxis? Wie hängen Forschung, Theorie und Praxis zusammen? Wie kann die Friedens- und Konfliktforschung hier eine Brücke sein? Wie kann Forschung in und mit der Praxis gemeinsam stattfinden?
Mit diesen Fragen beschäftigt sich der Workshop, der auf Erfahrungen des Praxis<->Forschungsseminars basiert, das 2017/2018 im Marburger M.A. Friedens- und Konfliktforschung als einjähriges Forschungsseminar stattfindet und Studierenden die Möglichkeit bietet, ihre Praxiserfahrungen forschend zu begleiten.
Im Workshop werden wir einen Einblick in unsere Erfahrungen mit dem Seminarprozess geben, indem wir unser Seminarkonzept vorstellen und einzelne Methoden gemeinsam anwenden, um das Verhältnis von Wissenschaft und Praxis zu erkunden. Wir wollen einen Reflexions- und Diskussionsraum für die Frage anbieten, welche Rolle dieses Spannungsfeld im Studium der Friedens- und Konfliktforschung einnehmen sollte.
Gemeinsam mit den Teilnehmenden des Workshops wollen wir Perspektiven für diese Form der Praxisforschung diskutieren und in die Zukunft einer stärkeren Integration von Praxiserfahrungen im Studium blicken. Wir freuen uns, wenn Teilnehmende ihre eigenen Fragen und Erfahrungen an und mit Praxisforschung(slehre) mitbringen.
Zur Tagungsbegleitung und als virtueller Abstractroom stehen auf dem Bretterblog nun die Beiträge der Jungen AFK-Konferenz „Welches Wissen(-)schafft Praxis?“ bereit, um sie im Vorfeld, parallel und im Nachhinein zu diskutieren und barrierefrei über die Tagungsgrenzen hinaus, thematische Anregungen zu liefern.

Welches Wissen schafft Forschung? Wie wird dieses Wissen geschaffen und wie verhält es sich zur Praxis? In welcher Beziehung stehen dabei Forscher*innen und Beforschte, speziell Forscher*innen oder Student*innen aus der Universität und Praktiker*innen, Aktivist*innen aus sozialen Bewegungen und/oder marginalisierte Personen?
Diesen Fragen wollen wir uns widmen, um daran anschließend über Macht und Herrschaft in Forschungsprojekten zu diskutieren und nach Möglichkeiten zu suchen, damit bewusst und solidarisch umzugehen. Ein Versuch, dem zu begegnen, bietet für uns die Wahl eines aktivistisch-partizipativen Methodenansatzes. Diesen möchten wir in seinen Grundlagen theoretisch erläutern und mit euch Potentiale, aber auch Herausforderungen und Grenzen thematisieren.
Vor allem mit Blick auf schon realisierte oder potentielle Forschungsprojekte mit „der Praxis“ erörtern wir so in diesem Workshop die Frage, ob ein aktivistisch-partizipativer Ansatz als ethisch-methodisches und erkenntnistheoretisches Korrektiv der Friedens- und Konfliktforschung dienen kann.
Junge AFK Workshop 2: Revolution – nicht nur im Ausstellungstitel, auch in der Wissenschaftspraxis?!
(2018)
Workshopleitung: Stella Kneifel und Sophie Bischoff
Wie kann universitäres Wissen alternativ vermittelt und auf unterschiedlichen Darstellungsebenen gezeigt werden? Wie können verschiedene Adressaten der Gesellschaft eingebunden, neue Perspektiven geschaffen und ein Lernen voneinander gefördert werden? Welche Chancen ergeben sich durch alternative Formate für die Friedens- und Konfliktforschung? Anhand des Praxisbeispiels der Fotoausstellung „Repression – Protest – Revolution“ gibt der Workshop Einblick in diese FrageDie Fotoausstellung wurde im Rahmen eines Seminars der Universität Erfurt von Studierenden und Geflüchteten erarbeitet. Das Konzept hierfür wurde von Mitarbeiterinnen der Professur Geschichte Westasiens und Masterstudierenden entworfen und danach in die Praxis umgesetzt. Im Workshop möchten zwei der Verantwortlichen ihre Erfahrungen mit der alternativen Methode universitären Lehrens teilen. Da die in Erfurt erarbeitete Ausstellung „Repression – Protest – Revolution“ auf der Konferenz zu sehen sein wird, ist es möglich, auf diese als Praxisbeispiel zurückzugreifen und einen praxisnahen Diskussionsraum zu schaffen.
Die Einführung soll dazu dienen, alternative Wissensformate für die universitäre Praxis im Allgemeinen und für Seminare im Speziellen vorzustellen. Dabei wird die Ausstellung als ein Beispiel herausgestellt und Möglichkeiten und Grenzen dieser aufgezeigt.
Anschließend soll, erstens, die Planung, die am Anfang jedes Projektes steht, diskutiert werden. Dazu gehört u.a. das Formulieren konkreter inhaltlicher und ästhetischer Ziele, das Erstellen eines Zeitplanes, aber auch das Heraussuchen geeigneter Arbeitsmaterialien.
Darüber hinaus wird es, zweitens, um die Durchführung in einem universitären Seminar gehen. Dabei geht es u.a. um die Motivation der Teilnehmenden, die sinnvolle Anwendung von Methoden der Wissensgenerierung oder auch die Art der Zusammenarbeit.
Drittens soll diskutiert werden, welche Chancen und Risiken alternative Darstellungsformen in der universitären Praxis haben. Dabei können die Seminarleiterinnen aus ihren eigenen Erfahrungen theoretische sowie praktische Tipps geben. Daran schließt sich die Frage an, welche Möglichkeiten alternative Wissensformate, wie eine Ausstellung, für die Friedens- und Konfliktforschung bieten.

Die Idee: Welchen Feminismus brauchen, wollen, leben wir? Unter dieser breiten Fragestellung möchten wir uns mit Teilnehmer*innen darüber austauschen, was Feminismus für uns nicht nur in der Wissenschaft und unserer wissenschaftlichen Praxis bedeutet.
Wie halten wir es eigentlich in unserem Alltag mit dem Feminismus? Wie und wann brauchen, wollen, leben wir Feminismus als Berufstätige, Selbstständige, Erwerbsarbeitssuchende, Elternteile, Alleinerziehende, Feldforschende, Kinderlose, Aktivist*innen und/oder vieles mehr? Fordern wir die Perspektiven und Rechte, die wir grundsätzlich vertreten, auch für uns selbst und für andere in unserem direkten Umfeld ein? Werden wir ihnen gerecht? Geht es uns vielleicht sogar um grundlegende, sozusagen revolutionäre Veränderungen der Herrschaftsverhältnisse? (Ver-)Zweifeln wir in bestimmten Situationen auch an feministischen Perspektiven und den Forderungen nach Frauenrechten?
Über diese und andere Fragen möchten wir sprechen und diskutieren. Wir wünschen uns einen ehrlichen, nachdenklichen und hoffentlich auch befreienden Austausch, der gerne auch wissenschaftlich inspirieren darf.
Das Akademiejahr 2018 hatte neben den beiden Schülerakademien für die Mittelstufe und die Oberstufe noch einen weiteren Höhepunkt: das Symposium "Kulturelle Bildung auf dem Weg" (vom 2. bis 4. März 2018, ausgerichtet von Burg Fürsteneck gemeinsam mit dem Schulentwicklungsprogramm KulturSchule des Hessischen Kultusministeriums und dem Weiterbildungsmaster Kulturelle Bildung an Schulen der Uni Marburg). Es wurde von unserem Schirmherrn, Kultusminister Prof. Dr. R. Alexander Lorz, eröffnet und hatte unter anderem das Ziel, in der Begegnung von Bildungsexpert*innen und -praktiker*innen eine Fachdebatte über "Qualitätsbedingungen in der Kulturellen Bildung am Beispiel der Schülerakademien und der Kulturschulen in Hessen" anzustoßen.
Die Erfahrung, "…dass alles auch ganz anders sein könnte" ist die wohl wichtigste Erfahrung in Bildungsprozessen. Die Entdeckung von Möglichkeiten, Perspektivwechseln und transformatorischen Selbst-Bildungsprozessen ist zentral für eine gelungene kulturelle Bildungssituation. (Birgit Mandel, 2005).
Die Hessischen Schülerakademien zur Förderung besonders engagierter und begabter junger Menschen wurden bewusst als ein Unterfangen des Forschenden Lernens gegründet und fühlen sich diesem Leitgedanken im Kontext kultureller Bildung verpflichtet. Dieser Satz klingt zunächst einmal gut und zeitgemäß. Doch was steckt genau dahinter?

„Welches Wissen(-)schafft Praxis?“. Diese Frage wollen wir zum Anlass nehmen, um über die komplexen Zusammenhänge von Wissenschaft und Praxis in der Friedensbewegung nachzudenken. Denn die sowohl begrüßte wie kritisierte Trennung von Wissenschaft und Aktivismus nehmen auch wir, die wir Berührungspunkte in beide Szenen haben, wahr, wollen in unserem Beitrag jedoch versuchen, sie differenzierter zu diskutieren. Zwei überspitzte Bilder kursieren in den Diskussionen: Auf der einen Seite der 60-jährige, bildungsbürgerliche, friedensbewegte Aktivist in seiner Jeansjacke, der die theoretischen Diskussionen bis höchstens in die 90er Jahre verfolgt hat. Auf der anderen Seite die Theoretiker*innen in ihren Elfenbeintürmen - unpolitisch, abgehoben und realitätsfern. Diese weit verbreiteten Narrationen greifen jedoch zu kurz und versperren den Blick auf die deutlich komplexeren Verhältnisse von Theorie, Wissen und Praxis.
Im Anschluss an wissenssoziologische Überlegungen wollen wir nachzeichnen, welche Zusammenhänge zwischen Wissen und Handeln von Praktikerinnen in der Friedensbewegung selbst hergestellt werden. Welche Deutungsmuster bezüglich der Friedens- und Konfliktforschung werden in der deutschen Friedensbewegung geteilt? Wie werden Theorien der Friedens- und Konfliktforschung in der Friedensbewegung rezipiert und wahrgenommen? An welchen Stellen verstehen sich Aktivistinnen selbst als Theoretikerinnen und welches Selbstverständnis haben sie von sich selbst als Praktikerinnen im Gegensatz zu Forschenden? Wo lassen sich Verbindungslinien zwischen Aktivistinnen und Wissenschaftlerinnen ausmachen? Und welche Erwartungen an die Friedens- und Konfliktforschung haben Menschen in der Friedensbewegung? Anhand von neu arrangierten Ergebnissen von Leitfadeninterviews mit hauptberuflichen Akteur*innen der deutschen Friedensbewegung werden wir verschiedene Arten des Bezuges auf Praxiswissen und akademisches Wissen aufzeigen. Zu vermuten ist, dass Theoriegenerierung, wie sie in der Friedens- und Konfliktforschung stattfindet, und die Produktion von Erfahrungswissen in der Bewegung nicht als zwei gegensätzliche Pole zu verstehen sind. Vielmehr, so unsere These, müssen Theorie- und Praxiswissen in einem ambivalenten Verhältnis gedacht werden. Ein solches Denken erlaubt, Differenzen zwischen Forschung und Praxis in ihrer Vielschichtigkeit anzuerkennen, aber als gesellschaftlich hergestellt zu reflektieren. Darüber hinaus wird der Blick auf die wechselseitige Hervorbringung und die Gleichzeitigkeit verschiedener Wissensbestände gerichtet. Ein solches relationales Verständnis von Forschung_Praxis_Bewegung ermöglicht, die Trennungslinien - zumindest an einzelnen Stellen - produktiv aufzulösen.
Der Workshop ist im ersten Teil als Lesung konzipiert, in der wir Interviewausschnitte neu arrangieren und so die Ansichten "der Friedensbewegung", die unsere Interviewpartnerinnen vertreten, zum Sprechen zu bringen. In der anschließenden Diskussion wollen wir mit den Teilnehmenden die Ergebnisse der Interviews und die Erfahrungen der Teilnehmenden gemeinsam reflektieren. Die Praktikerinnen im Dialog mit sich, mit uns und mit dem Publikum erlauben es, Theorie in Bewegung und Bewegung in die Theorie zu bringen.
