Die vorliegenden Texte sind die verschriftlichten und redigierten Beiträge eines internationalen Kolloquiums, das – organisiert von der École Pratique des Hautes Études, PSL, Paris, vom Institut für Kunstgeschichte der Universität Würzburg und der Universität Jaén – vom 1. bis 4. Juni 2022 in Paris stattfand und finanziell von der Deutsch-Französischen Hochschule unterstützt wurde.
Einer der neueren Trends in der Vor- und Frühgeschichtlichen Archäologie ist die Beschäftigung mit prähistorischen Konflikten. Zumeist beschränkt sich diese sogenannte Konfliktforschung jedoch auf eine bloße Gewaltforschung unter Vernachlässigung der Frage, was Konflikte als Konflikte eigentlich ausmacht und wie sie vermieden oder geregelt beigelegt werden können. Vor diesem Hintergrund verstehen sich die Beiträge in diesem Band als Theorieangebote an die Archäologie: Aus der Perspektive ihrer jeweiligen Disziplinen – Soziologie, Philosophie, Ethnologie, Archäologie, Geschichts- und Politikwissenschaften – gehen die Autorinnen und Autoren den Fragen nach, wie sich in Gesellschaften ohne (oder mit nur eingeschränkter) Zentralgewalt Dynamiken negativer Reziprozität darstellen und wie sie sich beenden lassen, welche Rolle dritte Parteien oder Instanzen dabei spielen können und welche Bedeutung der materiellen Kultur im Kontext dieser Prozesse zukommt.
Fostering Teacher Educators’ Intercultural Media-Related Competencies Using a Social VR Environment
(2023)
Recent studies suggest that teacher educators require intercultural media-related educational competencies to respond to contemporary and future educational needs. However, necessary professional development concepts, which are aimed at fostering these competencies, are underrepresented in current teacher education research. This study reports on the results of a case study within a Design-Based-Research project aimed at designing, implementing and evaluating a professional development concept to foster teacher educators’ intercultural media-related competencies. A remote workshop using a Social VR environment was conducted with a convenience sample of 10 teacher educators. Data collected through a qualitative pre-post survey and a focus group was interpreted through qualitative content analysis. Findings showed intercultural aspects were addressed in several domains as well as an increased ability to evaluate potentials and risks related to interculturally focused teaching and learning with Social VR.
Given the growing interest of corporate stakeholders in Metaverse applications, there is a need to understand accessibility of these technologies for marginalized populations such as people living with dementia to ensure inclusive design of Metaverse applications. We assessed the accessibility of extended reality technology for people living with mild cognitive impairment and dementia to develop accessibility guidelines for these technologies. We used four strategies to synthesize evidence for barriers and facilitators of accessibility: (1) Findings from a non-systematic literature review, (2) guidelines from well-researched technology, (3) exploration of selected mixed reality technologies, and (4) observations from four sessions and video data of people living with dementia using mixed reality technologies. We utilized template analysis to develop codes and themes towards accessibility guidelines. Future work can validate our preliminary findings by applying them on video recordings or testing them in experiments.
Digitalization is one of the global challenges for justice and This volume documents the presentations of a multilingual online conference on "Digitalization as a challenge for justice and administration" held in March 2022. The contributions of the international team of authors provide insights into central issues of this highly relevant subject from African, Japanese, U.S., Swiss, Latin American and German perspectives. The result is a multifaceted picture of digitalization in the context of public, private and even criminal law.

Fertilität und Macht: Die Reproduktionspflicht mittelalterlicher Herrscherinnen und Herrscher
(2021)
Fertility was a key theme of medieval rulership. To conceive and give birth to sons – and thus to ensure the succession to the throne – was one of the foremost duties of medieval kings and queens. But what happened when a male child died in infancy, no male child was born, or no pregnancy ever came about? Barrenness could have dramatic consequences in the Middle Ages, for example expulsion, divorce or conflicts over royal succession. Against this historical background, it seems logical that the fate of the childless ruler would be recounted in the form of a ‘Passion narrative’. In the German literature of the Middle Ages, however, there are also interpretative models of a contrary vein to be found. In the year 1220, for instance, Ebernand of Erfurt construed the wedded life of the imperial couple Henry and Kunigunde as a tale of resistance against the royal obligation to reproduce. In his versified legend, composed in the vernacular, the couple secretly agrees not to fulfil society’s expectations, but to lead a chaste marriage. Yet above and beyond legend, childless rulers were also subject to the impact of multifarious legal, religious, medical, narrative and discursive factors. Taking Michel Foucault as a point of departure, this contribution shows how fertility became a field of power on which hierarchies between rulers and subjects, men and women were negotiated, while also shedding light on how religious and secular ideals clashed in the assessment of infertility.
The combination of globalization and digitalization emphasizes the importance of media-related and intercultural competencies of teacher educators and preservice teachers. This article reports on the initial prototypical implementation of a pedagogical concept to foster such competencies of preservice teachers. The proposed pedagogical concept utilizes a social virtual reality (VR) framework since related work on the characteristics of VR has indicated that this medium is particularly well suited for intercultural professional development processes. The development is integrated into a larger design-based research approach that develops a theory-guided and empirically grounded professional development concept for teacher educators with a special focus on teacher educator technology competencies (TETC8). TETCs provide a suitable competence framework capable of aligning requirements for both media-related and intercultural competencies. In an exploratory study with student teachers, we designed, implemented, and evaluated a pedagogical concept. Reflection reports were qualitatively analyzed to gain insights into factors that facilitate or hinder the implementation of the immersive learning scenario as well as into the participants’ evaluation of their learning experience. The results show that our proposed pedagogical concept is particularly suitable for promoting the experience of social presence, agency, and empathy in the group.
Both research and policy indicate the importance of considering ICT-related and intercultural competence development in education together. Teacher educators play a significant role in the development of these related competencies. The aim of this study is to analyze ICT- related competence frameworks addressing teacher educators, focusing on how they incorporate intercultural considerations. We analyze four internationally recognized models—Teacher Educator Technology Competencies (TETCs), DigCompEdu, Jisc Digital Capabilities, and Media Didactica—showing that with the TETCs important steps have been taken to integrate both discourses, while the other frameworks treat aspects related to culture as isolated phenomena. In TETC 8, the global dimension is represented by a specific competency, which is also differentiated into specific areas of competence. This offers a strong starting point for further international discourse, in terms of both the diversification of underlying theoretical concepts and approaches to culturally responsive education. Further research is needed to investigate how professional development can meet the needs of teacher educators in a global context.

Natural walking in virtual reality games is constrained by the physical boundaries defined by the size of the player’s tracking space. Impossible spaces, a redirected walking technique, enlarge the virtual environment by creating overlapping architecture and letting multiple locations occupy the same physical space. Within certain thresholds, this is subtle to the player. In this paper, we present our approach to implement such impossible spaces and describe how we handled challenges like objects with simulated physics or precomputed global illumination.
In this paper, we bridge the gap between procedural content generation (PCG) and user-generated content (UGC) by proposing and demonstrating an interactive agent-based model of self-assembling ensembles that can be directed though user input. We motivate these efforts by considering the opportunities technology provides to pursue game designs based on according game design frameworks. We present three different use cases of the proposed model that emphasize its potential to (1) self-assemble into predefined 3D graphical assets, (2) define new structures in the context of virtual environments by self-assembling layers on the surfaces of arbitrary 3D objects, and (3) allow novel structures to self-assemble only considering the model’s configuration and no external dependencies. To address the performance restrictions in computer games, we realized the prototypical model implementation by means of an efficient entity component system (ECS). We conclude the paper with an outlook on future steps to further explore novel interactive, dynamic PCG mechanics and to ensure their efficiency.
Immersive virtual environments provide users with the opportunity to escape from the real world, but scripted dialogues can disrupt the presence within the world the user is trying to escape within. Both Non-Playable Character (NPC) to Player and NPC to NPC dialogue can be non-natural and the reliance on responding with pre-defined dialogue does not always meet the players emotional expectations or provide responses appropriate to the given context or world states. This paper investigates the application of Artificial Intelligence (AI) and Natural Language Processing to generate dynamic human-like responses within a themed virtual world. Each thematic has been analysed against humangenerated responses for the same seed and demonstrates invariance of rating across a range of model sizes, but shows an effect of theme and the size of the corpus used for fine-tuning the context for the game world.
Modern immersive multimodal technologies enable the learners to completely get immersed in various learning situations in a way that feels like experiencing an authentic learning environment. These environments also allow the collection of multimodal data, which can be used with artificial intelligence to further improve the immersion and learning outcomes. The use of artificial intelligence has been widely explored for the interpretation of multimodal data collected from multiple sensors, thus giving insights to support learners’ performance by providing personalised feedback. In this paper, we present a conceptual approach for creating immersive learning environments, integrated with multi-sensor setup to help learners improve their psychomotor skills in a remote setting.
Immersive, sensor-enabled technologies such as augmented and virtual reality expand the way human beings interact with computers significantly. While these technologies are widely explored in entertainment games, they also offer possibilities for educational use. However,their uptake in education is so far very limited. Within the ImTech4Ed project, we aim at systematically exploring the power of interdisciplinary, international hackathons as a novel method to create immersive educational game prototypes and as a means to transfer these innovative technical prototypes into educational use. To achieve this, we bring together game design and development, where immersive and interactive solutions are designed and developed; computer science, where the technological foundations for immersive technologies and for scalable architectures for these are created; and teacher education, where future teachers are educated. This article reports on the concept and design of these hackathons.
As part of the Clash of Realities International Conference on the Technology and Theory of Digital Games, the Game Technology Summit is a premium venue to bring together experts from academia and industry to disseminate state-of-the-art research on trending technology topics in digital games. In this first iteration of the Game Technology Summit, we specifically paid attention on how the successes in AI in Natural User Interfaces have been impacting the games industry (industry track) and which scientific, state-of-the-art ideas and approaches are currently pursued (scientific track).
Vom 16. bis 18. November 2018 fand im Kloster Windberg bei Straubing zum dritten Mal nach 2014 eine Tagung unter dem Titel "Neue Materialien des Bayerischen Neolithikums" statt. Dabei wurden neue, bislang unpublizierte Fundkomplexe vorgestellt und diskutiert, die alle Phasen der Jungsteinzeit vom Altneolithikum bis zum Endneolithikum abdeckten und die aus verschiedenen Landesteilen des Freistaats Bayern stammen. Mit einer diachronen und Regionen übergreifenden Betrachtung charakteristischer Inventare aus den verschiedenen Landschaftsräumen und Zeitabschnitten wurde das Ziel verfolgt, neues Material zu erschließen und damit die archäologische Quellenbasis zu erweitern und der Neolithforschung in Bayern neue Impulse zu geben. Im vorliegenden Band werden sieben der Vorträge dieser Tagung sowie drei Beiträge der vorangegangenen Arbeitstreffen zusammengestellt.
Texts, Animals, Environments. Zoopoetics and Ecopoetics probes the multiple links between ecocriticism and animal studies, assessing the relations between animals, environments and poetics. While ecocriticism usually relies on a relational approach to explore phenomena related to the environment or ecology more broadly, animal studies tends to examine individual or species-specific aspects. As a consequence, ecocriticism concentrates on ecopoetical, animal studies on zoopoetical elements and modes of representation in literature (and the arts more generally). Bringing key concepts of ecocriticism and animal studies into dialogue, the volume explores new ways of thinking about and reading texts, animals, and environments – not as separate entities but as part of the same collective.
Vom 18. bis 20. November 2016 fand im Kloster Windberg bei Straubing zum zweiten Mal nach 2014 eine Tagung unter dem Titel "Neue Materialien des Bayerischen Neolithikums" statt. Dabei wurden neue, bislang unpublizierte Fundkomplexe vorgestellt und diskutiert, die alle Phasen der Jungsteinzeit vom Altneolithikum bis zum Endneolithikum abdeckten und die aus verschiedenen Landesteilen des Freistaats Bayern sowie aus dem benachbarten Oberschwaben stammten. Mit einer diachronen und Regionen übergreifenden Betrachtung charakteristischer Inventare aus den verschiedenen Landschaftsräumen und Zeitabschnitten wurde das Ziel verfolgt, neues Material zu erschließen und damit die archäologische Quellenbasis zu erweitern und der Neolithforschung in Bayern neue Impulse zu geben. Im vorliegenden Band sind acht der Vorträge dieser Tagung zusammen gestellt.
Introduction: The prognosis of medullary thyroid carcinoma (MTC) is poor using common chemotherapeutic approaches. However, during the last years encouraging results of recently introduced tyrosine kinase inhibitors (TKI) such as vandetanib have been published. In this study we aimed to correlate the results of \(^{18}\)F-fluorodeoxyglucose ([\(^{18}\)F]FDG) positron emission tomography (PET) imaging with treatment outcome.
Methods: Eighteen patients after thyroidectomy with recurrent/advanced MTC lesions receiving vandetanib (300 mg orally/day) could be analysed. A baseline \(^{18}\)F-FDG PET prior to and a follow-up \(^{18}\)F-FDG PET 3 months after TKI initiation were performed. During follow-up, tumor progression was assessed every 3 months including computed tomography according to RECIST. Progression-free survival (PFS) was correlated with the maximum standardized uptake value of \(^{18}\)F-FDG in lymph nodes (SUV(LN)max) or visceral metastases (SUV(MTS)max) as well as with clinical parameters using ROC analysis.
Results: Within median 3.6 years of follow-up, 9 patients showed disease progression at median 8.5 months after TKI initiation. An elevated glucose consumption assessed by baseline \(^{18}\)F-FDG PET (SUV(LN)max > 7.25) could predict a shorter PFS (2 y) with an accuracy of 76.5% (SUV(LN)max <7.25, 4.3 y; p=0.03). Accordingly, preserved tumor metabolism in the follow-up PET (SUV(MTS)max >2.7) also demonstrated an unfavorable prognosis (accuracy, 85.7%). On the other hand, none of the clinical parameters reached significance in response prediction.
Conclusions: In patients with advanced and progressive MTC, tumors with higher metabolic activity at baseline are more aggressive and more prone to progression as reflected by a shorter PFS; they should be monitored more closely. Preserved glucose consumption 3 months after treatment initiation was also related to poorer prognosis.
Einleitung: Die linksventrikuläre diastolische Dysfunktion (LVDD) ist bei Diabetikern noch vor Entwicklung einer klinisch apparenten Herzinsuffizienz eines der ersten Anzeichen einer kardialen Beteiligung. Daher soll in dieser Studie untersucht werden, ob die LVDD mit ECG-gated F-18-FDG PET in einem Diabetes-Rattenmodell dargestellt werden kann.
Methodik: Es wurden F-18-FDG PET Scans in einem Typ-2-Diabetes Rattenmodell (ZDF fa/fa, n=6) und in ZL Kontrollen (n=6) vorgenommen (Alter, jeweils 13 Wochen). Unter Hyperinsulinemic-Euglycemic Clamp-Technik wurden 37 MBq 18F-FDG über die Schwanzvene appliziert. 15-35 Minuten nach Tracergabe wurden mittels eines Kleintier-PET-Scanners sowie unter EKG-Ableitung PET Scans angefertigt (16 frames/cardiac cycle). Die linksventrikuläre Ejektionsfraktion (EF) und die Peak Füllrate (PFR) wurden mittels einer geeigneten Software (Heart Function View) gemessen, wobei die Software an die Größe des Rattenherzes angepasst wurde.
Ergebnisse: Im Alter von 13 Wochen entwickeln ZDF Diabetes-Ratten eine im Vergleich zu Kontrolltieren eine signifikante myokardiale Hypertrophie, bestätigt durch post-mortem Analyse des Herzgewichtes (994±78mg vs. 871±44mg in ZDF Diabetes-Ratten vs. ZL Kontrollen, p<0.01). ECG-gated PET zeigte eine signifikante Abnahme der LV diastolischen PFR (10.4±0.5 vs. 11.8±0.4 EDV/sec in ZDF Diabetes-Ratten vs. ZL Kontrollen, p<0.001), jedoch zeigte sich kein signifikanter Unterschied zwischen LVEF und der Herzfrequenz in den untersuchten ZDF Diabetes-Ratten und Kontrollen (LVEF: 60.0±4.5 vs. 63.7±4.1%, n.s. und HR: 305±25 vs. 323±24 bpm, n.s.).
Schlussfolgerung: Im Diabetes-Ratten-Modell kann unter Verwendung eines ECG-gated FDG-PET Protokolls die diastolische Dysfunktion als Parameter der frühen diabetischen Kardiomyopathie nachgewiesen werden.
T-pattern analysis supports studies of various aspects of human or animal behavior as well as interaction between human subjects and animal or artificial agents. The following proceedings give an overiew on the application of T-pattern analysis in different research fields like media, gaming, human behaviour, social and organisational interaction as well as sports and health.
Eine wichtige Grundlage für die quantitative Analyse von Erzähltexten, etwa eine Netzwerkanalyse der Figurenkonstellation, ist die automatische Erkennung von Referenzen auf Figuren in Erzähltexten, ein Sonderfall des generischen NLP-Problems der Named Entity Recognition. Bestehende, auf Zeitungstexten trainierte Modelle sind für literarische Texte nur eingeschränkt brauchbar, da die Einbeziehung von Appellativen in die Named Entity-Definition und deren häufige Verwendung in Romantexten zu einem schlechten Ergebnis führt. Dieses Paper stellt eine anhand eines manuell annotierten Korpus auf deutschsprachige Romane des 19. Jahrhunderts angepasste NER-Komponente vor.
Unter dem Titel "Neue Materialien des Bayerischen Neolithikums" fand vom 21. bis 23. November 2014 im Kloster Windberg bei Straubing eine Tagung statt, bei der neue, bislang unpublizierte jung-steinzeitliche Fundkomplexe vorgestellt und diskutiert wurden, die aus allen Landesteilen des Freistaats Bayern stammten und zeitlich den Bogen von der Linienbandkeramik bis zu den Becherkulturen spannten. Mit einer diachronen und Regionen übergreifenden Betrachtung charakteristischer Inventare aus den verschiedenen Landschaftsräumen und Zeitabschnitten wurde das Ziel verfolgt, neues Material zu erschließen und damit die Quellenbasis für die archäologische Forschung zu erweitern sowie der Neolithforschung in Bayern neue Impulse zu geben. Im vorliegenden Band sind neun der Vorträge dieser Tagung zusammen gestellt.
Der Band versammelt aktuelle Beiträge, die der sprachwissenschaftlichen Erforschung der Kodifizierung der Sprache, insbesondere des Deutschen, gewidmet sind. Es finden sich sowohl historisch als auch gegenwartssprachlich, sowohl theoretisch als auch empirisch-exemplarisch orientierte Untersuchungen, Stellungnahmen und Ausblicke. Sprach-systematisch stehen phonetische, graphematische, syntaktische sowie soziolinguistische Blickrichtungen im Vordergrund. Darüber hinaus werden verschiedentlich die methodologischen Probleme reflektiert, die mit der Annahme eines Sprachkodex, seiner Formulierung und seiner möglichen Wirkung auf die Sprachentwicklung verbunden sind. Die meisten Aufsätze gehen auf eine entsprechende Tagung zurück, die im Februar 2015 am Institut für deutsche Philologie der Universität Würzburg stattfand.
Im Fokus der Tagung standen verschiedene Formen der Gewalt in ihrer Bindung an soziale Strukturen von der Steinzeit bis in das frühe Mittelalter. Die Beiträge blieben nicht auf das Thema Krieg beschränkt, das auch bereits Gegenstand einiger anderer Symposien war, sondern versuchten vielmehr, unterschiedliche Gewaltformen und Ebenen in ihrem gesellschaftlichen und kulturgeschichtlichen Kontext zu differenzieren. Da die meisten bisherigen Untersuchungen zu Gewalt und Krieg auf einzelne Epochen und Regionen bezogen sind, war ein Ziel der Tagung, eine diachrone und überregionale Betrachtungsweise anzuregen. Ein weiteres Hauptanliegen war die Förderung des interdisziplinären Dialogs zwischen Archäologie und Anthropologie.
In vielen Beiträgen wurde die nach wie vor häufig anzutreffende Gleichsetzung von Gewalt und Krieg kritisch hinterfragt und stattdessen deutlich gemacht, dass Gewalt in vielfältiger Form auch außerhalb des Kontexts kriegerischer Handlungen in mehr oder weniger „alltäglichen“ Situationen auftritt. Problematisch stellten sich dabei zunächst die verschiedenen divergierenden Definitionen des Gewaltbegriffs in unterschiedlichen Forschungstraditionen dar, ihre Gegenüberstellung führte aber schließlich zu einer ausgesprochen fruchtbaren Diskussion.
Ein wichtiges Fazit der Tagung ist, dass lineare Modelle zur Entwicklung der Gewalt in der Menschheitsgeschichte viel zu vereinfachend sind und einer differenzierten Betrachtung der Quellen weichen müssen. Gewalt fügt sich in kein einfaches evolutives Schema, sondern ist als kulturelles Phänomen Bestandteil gesellschaftlicher Prozesse. Sie muss in ihrem jeweiligen kulturhistorischen Kontext betrachtet und verstanden werden. Die im Rahmen des Symposiums präsentierten Fallbeispiele zeigten vielversprechende Ansätze hierzu auf. Eine Herausforderung für die Archäologie wird es jedoch sein, ein differenzierteres Bild der Vergangenheit auch interdisziplinär zu kommunizieren und gegen die nach wie vor dominanten, zur Übersimplifizierung neigenden Modelle im sozial- und kulturwissenschaftlichen Diskurs zu positionieren. Die Tagung „Gewalt und Gesellschaft“ versteht sich als Beitrag zur Weiterentwicklung tragfähiger archäologischer und anthropologischer Grundlagen für einen zukünftigen fundierten Dialog.
The International Symposium on Phytochemicals in Medicine and Food (ISPMF2015), organized by the Phytochemical Society of Europe (PSE) and the Phytochemical Society of Asia (PSA), was held June 26-29, 2015, in Shanghai of China. This was the first time that a PSE meeting has been held in Asia and a PSE-PSA joint symposium provided an opportunity for communication between scientists from Europe and Asia and other continents. ISPMF2015 has been jointly sponsored by Fujian Agriculture and Forestry University, Guizhou Medical University, Shanghai Normal University, Yancheng Institute of Technology, Beijing Normal University, and Fudan University. More than 270 scientists from 48 countries attended this meeting and presented their research and opinions on phytochemistry, phytomedicine and phytoneering. The international organizing committee and scientific advisory board of ISPMF 2015 comprised of outstanding scientists from around the globe. Dr. Jianbo Xiao was the chairman of the International Organizing Committee of ISPMF2015 and moderated the open address on June 26.
The organizing committee of ISPMF2015 assembled an exciting and diverse program, featuring 16 sessions including 12 plenary lectures, 20 invited talks, 55 short oral presentations, and more than 130 posters, which were dedicated to creating a podium for exchanging the latest research results in the phytochemicals for food and human health.
Das Programmheft zur Tagung zum Thema "Museum und Inklusion" enthält neben den abstracts aller ReferentInnen den Beitrag "Inklusionschancen und -grenzen taktiler Medien in der Kunstvermittlung" (Bastian Schlang und Jan Soldin unter Mitarbeit von Helen-Sophie Mayr und Maxim Reichow), eine "Auswahlbibliographie" (Simone Doll-Gerstendörfer unter Mitarbeit von Veronika Leikauf) sowie Informationen zu den Veranstaltern (Bayerische Museumsakademie, Bezirk Unterfranken, Museum am Dom, Professur für Museologie).
A simple test setup has been developed at Institute of Aerospace Information Technology, University of Würzburg, Germany to realize basic functionalities for formation flight of quadrocopters. The test environment is planned to be utilized for developing and validating the algorithms for formation flying capability in real environment as well as for education purpose. An already existing test bed for single quadrocopter was extended with necessary inter-communication and distributed control mechanism to test the algorithms for formation flights in 2 degrees of freedom (roll / pitch). This study encompasses the domain of communication, control engineering and embedded systems programming. Bluetooth protocol has been used for inter-communication between two quadrocopters. A simple approach of PID control in combination with Kalman filter has been exploited. MATLAB Instrument Control Toolbox has been used for data display, plotting and analysis. Plots can be drawn in real-time and received information can also be stored in the form of files for later use and analysis. The test setup has been developed indigenously and at considerably low cost. Emphasis has been placed on simplicity to facilitate students learning process. Several lessons have been learnt during the course of development of this setup. Proposed setup is quite flexible that can be modified as per changing requirements.
Based on the results of a 3-day workshop at the Brown University (2012) this white paper tries to sum up important topics and problems which came up in the presentations and discussions and to outline some general aspects of data modeling in digital humanities. Starting with an attempt to define data modeling it introduces distinctions like curation-driven vs. research-driven for a more general description of data modeling. The second part discusses specific problems and challenges of data modeling in the Humanities, while the third part outlines practical aspects, like the creation of data models or their evaluation.
Zhao Ji (1082-1135), better known as Emperor Huizong (r. 1100-1126) of the Southern Song Dynasty (960-1127) gained a reputation as supreme perfectionist as artist, art collector and connoisseur, a ruler devoted to the faith of Daoism, squandering a fortune on building palaces and halls and on landscape gardening. A famous example of his costly ‘folie de grandeur’ is the Sacred Northeast Mountain Peak Genyue, a gigantic rock garden in the northeast part of the Old City of the capital Kaifeng. The garden is described in sources such as the Huayanggong jishi (Description of the Florescent Solitary Palace) by the Buddhist monk Zu Xiu from 1127 and Zhang Hao’s (ca. 1180-1250) Genyue ji (Record of the Northeast Marchmount). The project in search of auspicious blessing started in 1118, having originated in the emperor’s conviction that the Daoist Immortals would descend to this exquisite paradise situated in the centre of the world, his capital. In his conviction the landscape garden that exceeded nature’s beauty would prolong and glorify his rule for ten thousand years. The Genyue was completed in January 1123, and thus became part of Emperor Huizong’s Divine Empyrean Daoist ideology of statecraft. Contrary to all auspicious symbolism, the Song’s emblematic demonstrations of power, and the necessity to meet political expectations, Emperor Huizong proved incapable of finding a solution to the disastrous situation at the northern frontier with Jin troupes moving onto his capital. Completed in 1123 the Genyue Marchmount was destroyed in the cold winter of 1126/1127 by the inhabitants of Kaifeng in their desperate struggle for survival in their besieged town.
Despite the internet's dynamic and collaborative nature, scientists continue to produce grant proposals, lab notebooks, data files, conclusions etc. that stay in static formats or are not published online and therefore not always easily accessible to the interested public. Because of limited adoption of tools that seamlessly integrate all aspects of a research project (conception, data generation, data evaluation, peerreviewing and publishing of conclusions), much effort is later spent on reproducing or reformatting individual entities before they can be repurposed independently or as parts of articles.
We propose that workflows - performed both individually and collaboratively - could potentially become more efficient if all steps of the research cycle were coherently represented online and the underlying data were formatted, annotated and licensed for reuse. Such a system would accelerate the process of taking projects from conception to publication stages and allow for continuous updating of the data sets and their interpretation as well as their integration into other independent projects.
A major advantage of such work ows is the increased transparency, both with respect to the scientific process as to the contribution of each participant. The latter point is important from a perspective of motivation, as it enables the allocation of reputation, which creates incentives for scientists to contribute to projects. Such work ow platforms offering possibilities to fine-tune the accessibility of their content could gradually pave the path from the current static mode of research presentation into a more coherent practice of open science.
Es wird argumentiert, daß bei der Prüfung der Homgenität von Zentren in mehrfaktoriellen Multicenter-Studien vor allem entscheidend ist, daß sich die Zentren in den faktoriellen Variablen nicht unterscheiden, deren Effekte in der späteren Auswertung interpretiert werden sollen. Dazu wird folgendes Procedere vorgeschlagen: (1) überprüfe, ob in allen Zentren die Randomisierungsbedingungen eingehalten wurden, (2) überprüfe, ob die Zentren homogen bezogen auf die eingebrachten Schichtvariablen (z.B. Geschlecht, Indikation) sind und (3) überprüfe, ob die Zentren homogen sind bezogen auf die Wechselwirkungen zwischen den eingebrachten faktoriellen Variablen. Es wird gezeigt, daß vor allem Forderung (3) für die Interpretationsfähigkeit der Ergebnisse von entscheidender Bedeutung ist. Möglichkeiten der statistischen Prüfung dieser Voraussetzungen werden an einem Beispiel aus der klinischen Prüfung eines Psychopharmakons vorgestellt.

K-Ar dating on hornblendes and micas from the TepläDomazlice zone revealed a pattern of dates which significantly deviates from the mid-Carboniferous to early Permian one that is found in the adjacent low-pressure metamorphic Moldanubian and Saxothuringian. Especially for the Mariänske Läzne metabasic complex, confirming early Czech determinations, the dates resemble the early Devonian pattern determined for the Münchberg Gneiss Massif and the Erbendorf-Vohenstrauß zone of northeastern Bavaria. This supports the idea that all three units are remnants of a huge complex which suffered a metamorphic overprint under medium-pressure conditions, probably in the early Devonian. Streng rejuvenation is found in the southern part of the Teplä-Domailice zone by which micas and even two hornblendes were reset to mid-Carboniferous ages. According to the geological setting, part of the apparently preDevonian dates may be explained by inherited argon from earlier metamorphic and magmatic events, e.g. the high-pressure metamorphism documented in eclogitic relics. However, excess argon, caused by the mid-Carboniferous overprint cannot be excluded.
Various amphibolites, metagabbros and eclogitic relics of the Mariänske Läzne complex, and amphibolites from the Cernä Hora Massif exhibit an uniform geochemical character which compares weil with modern mid-ocean ridge basalts. Geochemically these metabasites are similar to the amphibolites of the Myto area and to schistose, partly striped amphibolites of the neighbouring Tirschenreuth-Mähring Zone and the Erbendorf-Vohenstrauss Zone (Bavaria). Greenschists and amphibolites from the Domazlice metamorphic complex show an alkaline-basaltic tendency conforming to modern within-plate basalts or basalts from anomalaus midocean ridge segments. In their chemical character, these metabasites compare weil with the flaseramphibolites of the Erbendorf-Vohenstrauss Zone. Fine-grained amphibolites in the Warzenrieth area and (gabbro-) amphibolites in the Blätterberg-Hoher Bogen area show normal MORB character. The metamorphosed gabbroic rocks in the southern part of the Neukirchen-Kdyne (meta-) igneous complex are subalkaline - tholeiitic and exhibit a magmatic differentiation trend. They differ from the neighbouring amphibolites by generally lower contents of incompatible elements.

To study the activation of HIV by human spumaretrovirus (HSRV) the long terminal repeats (LTRs) of HSRV, HIVl and HIV2 were examined with respect to their ability to function as transcriptional promoters in virus infected and uninfected cells. Transient transfections using plasmids in which the L TRs of the three viruses were coupled to the bacterial chloramphenicol acetyltransferase (CA T) gene revealed (i) the level of cat gene expression directed by the HSRV LTR was markedly increased in HSRV infected cells compared to uninfected cells, (ii) cat gene expression driven by the HIV1 LTR, but not by the HIV2 LTR could be enhanced upon HSRV infection, whereas (iii) neither in HIV1 nor in HIV2 infected cells an effect on HSRV LTR driven cat geneexpression was detected.
Neoplasia in Xiphophorus can be classified into: a) a Jarge group triggered by carcinogens; b) a large group triggered by promoters; and c) a small group that develops "spontaneously" according to Mendelian Jaw. The process leading to susceptibility for neoplasia is represented by the disintegration of gene systems that normally protect the fish from neoplasia. Interpopulational arid interracial hybridization is the most effective process that Ieads to disintegration of the protective gene systems. Environmental factors may complete disintegration in somatic cells and thus may trigger neoplasia. The applications of the findings on Xiphophorus to humans are discussed.
The capacity of Xiphophorus to develop neoplasia can be formally assigned to a "tumor gene" (Tu), which appears to be a normal part of the genome of all individuals. The wild fish have evolved population-specific and cell type-specific systems of regulatory genes (R) for Tu that protect the fish from neoplasia. Hybridization of members of different wild populations in the laborstory followed by treatment of the hybrids with carcinogens led to disintegration of the R systems permitting excessive expression of Tu and thus resulting in neoplasia. Certain hybrids developed neoplasia even spontaneously. Observations on the genuine phenotypic effect of the derepressed Tu in the early embryo indicated an essential normal function of this oncogene in cell differentiation, proliferation and cell-cell communication. Tu appeared to be indispensable in the genome but may also be present in accessory copics. Recently, c-src, the cellular homolog of the Rous sarcoma virus oncogene v-src, was detected in Xiphophorus. The protein product of c-src, pp60c-src, was identified and then examined by its associated kinase activity. This pp60c-src was found in all individuals tested, but, depending on the genotype, its kinase activity was different. The genetic characters of c-src, such as linkage relations, dosage relations, expression, etc., correspond to those of Tu. From a systematic study which showed that pp60c-src was present in all metazoa tested ranging from mammals down to sponges, we concluded that c-src has evolved with the multicellular organization of animals. Neoplasia of animals and humans is a characteristic closely related to this evolution. Our data showed that small aquariurn fish, besides being used successfully because they are time-, space-, and money-saving systems for carcinogenicity testing, are also highly suitable for basic studies on neoplasia at the populational, morphological, developmental, cell biological, and molecular levels.
Characterization of the env gene and of two novel coding regions of the human spumaretrovirus
(1988)
Recombinant clones harboring retroviral DNA were established. The nucleotide sequence of the central and 3' region of the genome of the human spumaretrovirus was determined. The 5' end of the deduced protein sequence was homologaus to the endonuclease domain of retroviral reverse transcriptases. A small intergenic region is followed by a lang open reading frame of 985 aminoacid residues that according to its genomic location and structural features is a typical retroviral env gene. Surprisingly, the postenv region contains two open reading frames that encodes two novel retroviral genes, termed bel-l and bel-2. The 3' LTR is 963 nucleotides lang and contains the signal sequences characteristic for transcriptional regulation of retrovirus genomes.
The psychological and physiological effects of a socially oriented sensitivity training were evaluated. It is shown that decreased physical distance as well as increased intimacy yields high activation, both in psychological measures (experienced stress) and in pulse frequences. One result (highly significant and replicated in other experiments) was paradoxical: when Ss had to caress the face of a heterosexual vis-a-vis, they reported high experienced stress, but pulse frequences dropped rapidely below the resting pulse. Some suggestions are made to explain these findings. The question arises whether an autonomic somatic process, induced by social Stimulation, but independent of the cognitive coping is responsible for these results.
Summary (Social Situations as Experimental Conditions in Psychopharmacology): To reduce a great variability of drug effects in healthy subjects, stress conditions are used often in pharmacopsychology. However, empirical results show that the desired stress effects are failing. This paper suggests to realize social stress Situations as interactions between subjects, expecting higher challenging effects than experimentator-subject-interactions, usually used in experimental designs. Two experimental studies are reported: the call-upsituation and the group-therapy situation. The experimental effects were measured by changes of pulse-frequencies. The results indicate that in the two situations high and low dosages of tranquilizing drugs lead to comparable (and so predictable) effects only, if a Situation is high challenging for the experimental subjects. The call-up situation, which proves performance, challenges male subjects highly. The emotional or social competence demanding group-therapy situation is a high challenging situation for warnen. It is concluded that no situation is stressing a person generally. Depending from personality characteristics, differential stressor effects appear. Consequences for experiments in pharmacopsychology are discussed.

Melanotic melanoma (MM) of Xiphophorus (Teleostei: Poeciliidae) was studied by conventional preparations and freeze-etch preparations for electron microscopy. MM of Xiphophorus exhibits tightly packed pigment cells with prominent dendritic processes and interdigitations of their plasma membranes. The most impressive feature of MM cells is the occurrence of Iarge lobulated nuclei with numerous nuclear pores and some nuclear pockets. Abundant spheroidal or ellipsoidal melanosomes (diameter 200-650 nm) and vesicular structures are distributed throughout the cellular dendrites, whereas the perinucJear cytoplasm is free of melanosomes.
A further characteristic feature of melanoma cells in fish is the occurrence of melanosome complexes (i.e., "compound melanosomes"). These melanosome complexes consist of a few to numerous melanosomes, which are enveloped by a separate rnembrane. Pinocytotic vesicles couJd be demonstrated with distinct differences in frequency and distribution patterns, indicating differences in the metabolic activities of the cells in the same melanoma. Intercellular junctions are lacking in the MM cells.
The conventional TEM technique showed clear advantages in the demonstration of intemal architecture of organelles, whereas FE bad considerable potential in respect to the visualization of membrane surface specializations.
Neoplasia in Xiphophorus can be classified into a) a large group that is triggered by carcinogens; b) a large group triggered by promoters; c) a small group that develops "spontaneously" following interpopulational and interracial hybridizations; and d) a small group that develops "spontaneously" following germ line mutation. The process leading to susceptibility for neoplasia is represented by the disintegration of gene systems that normally protect the fish from neoplasia. Hybridization is the most effective process that leads to disintegration of the protection gene systems. Environmental factors may complete disintegration and thus may trigger neoplasia. It is discussed whether the findings on Xiphophorus may also apply to humans.

The binding of tritiated benzo(a)pyrene (BP) to liver DNA of 25 adult male rats (SIV 50) has been determined 50 h after a single intraperitoneal injection of doses between 40 ug/kg and 4; mg/kg. The dose-response relations~ ip is linear up to i mg/kg, shows a sigmoid step towards 2 mg/kg and a shallow linear. slope above that value. TlJe 0 bserved bin ding ranges from 1.7 to 180 nmoles BP per mole DNA phosphate. The non-linearity between 1 and 2 mg/kg could be explained 0):1 the basis of an induction of metabolizing enzymes. A pure1y mathematical extrapolation of therumour incidence from a carcinogenic dose (1 x 40mg/kg for a 20% hepatoma incidence in newborn mice) to human exposure levels (aboilt 0.1 ug/kg per day) would never have followed a step like the on~ found in our experiments. Our dose-effect study therefore shows how carcinogenitity data could be extrapolated in a biologically founded way to low doses.
The influence of microsomal (mAHH) and nuclear (nAHH) aryl hydrocarbon hydroxylase activity on the covalent binding of t:titiated benzo(a)pyrene to rat liver DNA was evaluated in vivo. Induction ofmAHH was obtained after phenobarbitone treatment (180% of control), which increased DNA binding to 210%, but left the nAHH unchanged. mAHH and nAHH were slightly indilced with dieldrin (130% and 120%), but the binding remairred unchanged. The increasing effect of mAHlt as weil as the possibly decreasing effect of nAHH induction on the binding became obvious when the data of 11 individual rats were used to solve the equation Binding = aX(mAHH) + bX(nAHH) + c. Multiple linear regression analysis resulted in positive values for a and c, a negative value for b, and a multiple correlation coefficient R = 0.82. An influence of other enzymes involved in the metabolism of benzo(a)pyrene cannot be excluded. The Study shows clearly that the binding of a foreign compound to DNA in vivo is not only dependent on microsomal enzyme activities but also on nuclear activities even if the latter are considerably lower than those of mic'rosomes.
Many mutagens and carcinogens act via covalent interaction of metabolic intermediates with DNA in the target cell. This report groups those structural elements which are often found to form the basis for a metabolism to such chemically reactive metabolites. ~mpounds which are chemically reactive per se and which do not require metabolic activation form group 1. Group 2 compri~es of olefins and aromatic hydrocarbons where the oxidation via an epoxide can be responsible for the generation of reactive species. Aromatic amines, hydrazines, and nitrosamirres form group 3 requiring an oxidation of a nitrogen atom or of a carbon atom in alpha position to a nitrosated amine. Group 4 compounds are halogenated hydrocarbons which can either give rise to radicals or can form an ·olefin (group 2) upon dehydrohalogenation. Group 5 compounds depend upon some preceding enzymatic activity either not available in the target cell or acting on positions in the molecule which are not directly involved in the subsequent formation of electrophilic atoms. Examples for each group are taken from the "List of Chemieals and Irrdustrial Processes Associated with Cancer in Humans" as compiled by the International Agency for the Research on Cancer, and it is shown that 91% of the organic carcinogens would have been detected on the basis of structural elements characteristic for group 1-5. As opposed to this very high sensitivity, the specificity ( the true negative fraction) of using this approach as a short-term test for carcinogenicity is shown to be bad because detoxification pathways have so far not been taken into account. These competing processes are so complex, however, that either only very extensive knowledge about pharmacokinetics, stability, and reactivity will be required or that in vivo systems have to be used to predict, on a quantitative basis, the darnage expected on the DNA. DNA-binding experiments in vivo are presented with benzene and toluene to demonstrate one possible way for an experimental assessment and it is shown that the detoxification reaction at the methyl group available only in toluene gives rise to a reduction by at least a factor of forty for the binding to rat liver DNA. This quantitative approach available with DNA-binding tests in vivo, also allows evaluation as to whether reactive metabolites and their DNA binding are always the most important single activities contributing to the overall carcinogenicity of a chemical. With the example of the livertumor inducing hexachlorocyclohexane isomers it is shown that situations will be found where reactive metabolites are formed and DNA binding in vivo is measurable but where this activity cannot be the decisive mode of carcinogenic action. It is concluded that the lack of structural elements known to become potentially reactive does not guarantee the lack of a carcinogenic potential.

Follow-ups across discourse domains: A cross-cultural exploration of their forms and functions
(2012)
The edited volume documents the proceedings of the ESF workshop "Follow-ups across discourse domains: a cross-cultural exploration of their forms and functions". It examines the forms and functions of the dialogue act of a follow-up, viz. accepting or challenging a prior communicative act, in political discourse across spoken and written dialogic genres. Specifically, it considers (1) the discourse domains of political interviews, editorials, op-eds and discussion forums, (2) their sequential organization as regards the status of initial (or 1st order) follow-up, a follow-up of a prior follow-up (2nd order follow-up), or nth-order follow-up, and (3) their discursive realization as regards degrees of indirectness and responsiveness which are conceptualized as a continuum along the lines of degrees of explicitness and degrees of responsiveness. The chapters come from the fields of linguistics, discourse analysis, socio-pragmatics, communication, political science and psychology, examining the heterogeneous field of political discourse and its manifestation in diverse discourse genres with respect to evasiveness, indirectness and redundancy in mediated political discourse, professional discourse, discourse identity and doing politics, to name but the most prominent questions.

Viele Studierende der Geschichte und anderer Geisteswissenschaften streben das Lehramt an. Darin Fuß zu fassen, wird in den kommenden Jahren immer schwieriger. Andere Studierende haben sogar überhaupt keine Vorstellungen von ihrer beruflichen Zukunft. Dieser Leitfaden möchte Orientierung bei der Berufswahl vermitteln und mit Hilfe von Experten Perspektiven eröffnen.
For the EU “effective multilateralism” in, with and within international organisations is the foundation of a system of global governance, so is laid down in the ESS. Therefore the term is used to label the EU’s activities in the UN-family and to characterise the relations with the UN in the wider context of global governance. It is the political argument for the EU’s commitment in military crisis management, side by side with UN peacekeepers. The UN in turn speaks of multilateralism to call for the EU’s loyalty and partnership. Both organisations build their partnership on the common normative ground of multilateralism. The paper questions these rhetorical denominations critically. It goes beyond the political declarations to analyse the degree and quality of “effective multilateralism” in reality in and with international organisations, using the example of UN-EU-relations in military crisis management. The theoretical approach of multilateralism serves as the starting point of the analysis and theoretical basis of the paper (Chapter 1). The special EU-touch in “effective multilateralism” in comparison to the “UN-touch” is subject of Chapter 2. This analysis is necessary due to the meanwhile inflationary use of the term “effective multilateralism” in almost every CSFP context. Are the institutional steps to a partnership in crisis management as well as the operational collaboration in DR Congo (2003/2006/2009) and Chad/CAR (2008/2009) in line with “multilateralism”? is the question that is answered in the paper (Chapter 3).
Fulgurites (= natural glasses formed by lightning strikes to the ground) are indicators of thunderstorms (e.g. Julien 1901). The distribution pattern of fulgurites in the study area (Grand Erg de Bilma and Erg de Tenere between 11.5°E and 16.5° and 18.5°N) shows decreasing fulgurite concentration from south to north. The fulgurite sites are concentrated in the area of fossil dune complexes, where they occur topographically above palaeolimnic deposits in mid-slope position of interdune depressions.
