Arab, Arab-American, American: Hegemonic and Contrapuntal Representations, explores the US mainstream discourse on the Arabs in the 1990s in different cultural texts: academic, popular and media, including Hollywood. The project investigates how these representational practices participate in the reconfiguration of American public opinion vis-à-vis the Arabs. It also focuses on the ways in which the various discourses that produce or even invent the "Other" are undeniably linked to the local and global power relations associated with their specific locations. Inspired by Edward Said's contrapuntal methodology, Gayatri Spivak's anti-essentialist postcolonial critique, and Ella Shohat and Robert Stam's polycentric multiculturalism, the book also makes space to examine counter-narratives and Arab perspectives. Arab, Arab-American, American´s analysis of the representation of Arabs in the US dominant media and Hollywood unravels the limits of liberalism and the "vestigial thinking" of Eurocentrism, at the heart of which demonizing or patronizing Arabs is still the norm. The book also offers a rigourous analysis of US foreign policy in the Arab world and addresses both the reality of imperialism in relation to its enablers, and the economic terrorism of neoliberalism in its various linkages with Islamic fundamentalism.

Trotz ihrer zunehmenden wissenschaftlichen und praktischen Bedeutung sind die Zusammenhänge zwischen Umwelt und Friedenskonsolidierung (engl. peacebuilding) noch wenig erforscht. Während in der Forschungsliteratur mehrere Möglichkeiten identifiziert werden, wie gemeinsam genutzte natürliche Ressourcen als Katalysatoren für den Frieden zwischen Konfliktparteien fungieren können, gibt es kaum empirische Belege für eine direkte Verbindung zwischen Umweltkooperation und nachhaltigem Frieden. Diese Dissertation untersucht umweltbezogene Friedenskonsolidierung (engl. environmental peacebuilding) und vertieft das theoretische Verständnis des Phänomens durch eine systematische Übersicht des Forschungsstands sowie zwei empirische Fallstudien. Auf diese Weise trägt die vorliegende Arbeit zur dringend benötigten konzeptionellen Schärfung und gleichzeitig zu einem empirisch fundierten Verständnis von Environmental Peacebuilding bei. Die Dissertation ist kumulativ aufgebaut und besteht aus drei Forschungsarbeiten. Das erste Paper befasst sich mit den Bausteinen des Environmental Peacebuilding und nimmt eine Bestandsaufnahme des Phänomens vor. Es schlägt Wege und Möglichkeiten vor, wie der Fokus von Umweltkonflikten auf Umweltkooperation und Frieden verlagert werden kann. Die beiden Fallstudien basieren auf qualitativen Methoden und untersuchen, wie Environmental Peacebuilding in zwei unterschiedlichen Kontexten, dem Nahen Osten und Westafrika, abläuft. Mit diesen beiden Arbeiten leistet die Dissertation einen empirischen Beitrag zur Environmental-Peacebuilding-Forschung und schließt eklatante Forschungslücken insbesondere hinsichtlich der Rolle von lokalen Gemeinschaften und privaten Akteuren im Environmental Peacebuilding. / Despite their increasing prominence in both research and practice, the interlinkages between the biophysical environment and peacebuilding remain under-researched. While the literature identifies several mechanisms through which shared natural resources can function as catalysts for peace between conflicting parties, empirical evidence asserting a direct link between environmental cooperation and sustainable peace remains scarce. This dissertation examines environmental peacebuilding. It does so by providing a better theoretical understanding of the phenomenon through a literature review and two empirical case studies. In so doing, this dissertation provides much needed conceptual clarity as well as empirical evidence on environmental peacebuilding. This dissertation is cumulative and consists of three research papers. The first paper deals with the building blocks of environmental peacebuilding and takes stock of the phenomenon. It proposes a coherent framework through which focus can be shifted from environmental conflicts to environmental cooperation and peace thereby also adding to the ‘how’ of environmental peacebuilding. The two case studies are based on qualitative methods. They explore how environmental peacebuilding unrolls in two different contexts, the Middle East and West Africa. With these two papers, this dissertation contributes empirical evidence to the environmental peacebuilding literature and fills gaps in the research, especially concerning the role of local communities and private actors in environmental peacebuilding processes.

Heuristics are mental shortcuts applied, consciously, subconsciously or both, to save time and efforts at the expense of risking the accuracy of the outcome. Therefore, one might argue that it is just an accuracy-effort trade-off. Nonetheless, we ought to recognize the distinction between the circumstances of risk, where all choices, outcomes, and probabilities might be generally known, and the circumstances of uncertainty, where, at least some, are not. Traditional models like the Subjective Expected Utility (SEU) work best for decisions under risk but not under uncertainty, which portrays most situations people need to tackle. Uncertainty requires simple heuristics that are sufficient instead of perfect. In this dissertation, the notion of heuristics was researched through a comprehensive historical review that unfolded the heuristics-linked ideas of significant scholars. An explicit distinction between the deliberate and the automatic heuristics was stated with chronological categories of pre and post-introduction of the SEU theory; providing a new perspective and opening a discussion for future research to consider. Additionally, qualitative and quantitative studies were applied that produced an unsophisticated heuristic set that was used by entrepreneurs in the Middle East and Germany. Perhaps entrepreneurs, and people in general, do not always know or acknowledge their use of heuristics. But still, they use it extensively and may exchange heuristics among others. That may lead us to think that in a world where uncertainty prevails, the Homo heuristicus might become a real threat to the Homo economicus.

Die folgende Arbeit ist Teil des multidisziplinären Projektes DESERT (DEad SEa Rift Transect), welches seit dem Jahr 2000 im Nahen Osten durchgeführt wird. Dabei geht es primär um die Struktur der südlichen Dead Sea Transform (DST; Tote-Meer-Transformstörung), Plattengrenze zwischen Afrika (Sinai) und der Arabischen Mikroplatte. Seit dem Miozän beträgt der sinistrale Versatz an dieser bedeutenden aktiven Blattverschiebung mehr als 100 km. Das steilwinkelseismische (NVR) Experiment von DESERT querte die DST im Arava Tal zwischen Rotem Meer und Totem Meer, wo die Hauptstörung auch Arava Fault genannt wird. Das 100 km lange Profil erstreckte sich von Sede Boqer/Israel im Nordwesten nach Ma'an/Jordanien im Südosten und fällt mit dem zentralen Teil einer weitwinkelseismischen Profillinie zusammen. <br><br> Steilwinkelseismische Messungen stellen bei der Bestimmung der Krustenstruktur bis zur Krusten/Mantel-Grenze ein wichtiges Instrument dar. Obwohl es kaum möglich ist, steilstehende Störungszonen direkt abzubilden, geben abrupte Veränderungen des Reflektivitätsmuster oder plötzlich endende Reflektoren indirekte Hinweise auf Transformbewegung. Da bis zum DESERT Experiment keine anderen reflexionsseismischen Messungen über die DST ausgeführt worden waren, waren wichtige Aspekte dieser Transform-Plattengrenze und der damit verbundenen Krustenstruktur nicht bekannt. Mit dem Projekt sollte deshalb untersucht werden, wie sich die DST sowohl in der oberen als auch in der unteren Kruste manifestiert. Zu den Fragestellungen gehörte unter anderem, ob sich die DST bis in den Mantel fortsetzt und ob ein Versatz der Krusten/Mantel-Grenze beobachtet werden kann. So ein Versatz ist von anderen großen Transformstörungen bekannt. <br><br> In der vorliegenden Arbeit werden zunächst die Methode der Steilwinkelseismik und die Datenverarbeitung kurz erläutert, bevor die Daten geologisch interpretiert werden. Bei der Interpetation werden die Ergebnisse anderer relevanter Studien berücksichtigt. Geologische Geländearbeiten im Gebiet des NVR Profiles ergaben, dass die Arava Fault zum Teil charakterisiert ist durch niedrige Steilstufen in den neogenen Sedimenten, durch kleine Druckrücken oder Rhomb-Gräben. Ein typischer Aufbau der Störungszone mit einem Störungskern, einer störungsbezogenen Deformationszone und einem undeformierten Ausgangsgestein, wie er von anderen großen Störungszonen beschrieben worden ist, konnte nicht gefunden werden. Deshalb wurden zur Ergänzung der Reflexionsseismik, welche vor allem die tieferen Krustenstrukturen abbildet, ASTER (Advanced Spacebourne Thermal Emission and Reflection Radiometer) Satellitendaten herangezogen, um oberflächennahe Deformation und neotektonische Aktivität zu bestimmen. / Following work is embedded in the multidisciplinary study DESERT (DEad SEa Rift Transect) that has been carried out in the Middle East since the beginning of the year 2000. It focuses on the structure of the southern Dead Sea Transform (DST), the transform plate boundary between Africa (Sinai) and the Arabian microplate. The left-lateral displacement along this major active strike-slip fault amounts to more than 100 km since Miocene times. The DESERT near-vertical seismic reflection (NVR) experiment crossed the DST in the Arava Valley between Red Sea and Dead Sea, where its main fault is called Arava Fault. The 100 km long profile extends in a NW&mdash;SE direction from Sede Boqer/Israel to Ma'an/Jordan and coincides with the central part of a wide-angle seismic refraction/reflection line. <br><br> Near-vertical seismic reflection studies are powerful tools to study the crustal architecture down to the crust/mantle boundary. Although they cannot directly image steeply dipping fault zones, they can give indirect evidence for transform motion by offset reflectors or an abrupt change in reflectivity pattern. Since no seismic reflection profile had crossed the DST before DESERT, important aspects of this transform plate boundary and related crustal structures were not known. Thus this study aimed to resolve the DST's manifestation in both the upper and the lower crust. It was to show, whether the DST penetrates into the mantle and whether it is associated with an offset of the crust/mantle boundary, which is observed at other large strike-slip zones. <br><br> In this work a short description of the seismic reflection method and the various processing steps is followed by a geological interpretation of the seismic data, taking into account relevant information from other studies. Geological investigations in the area of the NVR profile showed, that the Arava Fault can partly be recognized in the field by small scarps in the Neogene sediments, small pressure ridges or rhomb-shaped grabens. A typical fault zone architecture with a fault gauge, fault-related damage zone, and undeformed host rock, that has been reported from other large fault zones, could not be found. Therefore, as a complementary part to the NVR experiment, which was designed to resolve deeper crustal structures, ASTER (Advanced Spacebourne Thermal Emission and Reflection Radiometer) satellite images were used to analyze surface deformation and determine neotectonic activity.
