Abstract Konferenz 200 Jahre Wiener Kongress Martin Uhrmacher Neue Staaten – neue Grenzen. Die Großregion zwischen den Grenzbereinigungen des Ancien Régime und der Neuordnung durch den Wiener Kongress (1779 – 1816). Der Vortrag untersucht die Veränderung von Grenzen und Ihre Entwicklung von sich teils überlagernden und durch Enklaven und Gemeinsherrschaften durchsetzten historisch gewachsenen Grenzsäumen hin zu begradigten, fest definierten und teils naturräumlichen Scheidelinien folgenden Staatsgrenzen. In der heutigen Großregion vollzog sich dieser fundamentale Wandel in nur drei Jahrzehnten: Er gliederte die Region vollkommen neu. Zunächst waren es 1779 mit dem Brüsseler Vertrag nach jahrzehntelangen Verhandlungen endlich zu einem Ausgleich zwischen Österreich und Frankreich gekommen, der die Grenzstreitigkeiten beseitigte und neue, begradigte Grenzen exakt festlegte. Ein ähnlicher Vertrag wurde auch zwischen Österreich und Kurtrier abgeschlossen. Doch die als endgültig geplanten Regelungen bestanden nur wenige Jahre: Infolge der französischen Revolution annektierte die französische Republik am 1. Oktober 1795 die österreichischen Niederlande mit dem Herzogtum Luxemburg und kurz darauf auch Kurtrier und die anderen linksrheinischen Territorien. Alle Staaten wurden aufgelöst und gehörten nun zum französischen Staatsgebiet; Teile der alten Grenzen bestanden als Départementsgrenzen weiter. Nach der Absetzung Napoleons beschloss der Wiener Kongress 1815 eine Neuordnung Europas. Doch im Maas-Moselraum blieben mit Ausnahme Frankreichs alle Territorien und Landesherrschaften, die hier seit dem Früh- und Hochmittelalter bestanden hatten verschwunden. Sie wurden ersetzt durch das neu gegründete Großherzogtum Luxemburg und das ebenfalls neu gegründete Königreich der Vereinigten Niederlande sowie durch die preußische Rheinprovinz, die den gesamten östlichen Teil umfasste. Bei der territorialen Neugliederung griff man in Teilen auf die bis 1795 bestehenden Grenzen des alten Herzogtums zurück. In der Schlussakte des Wiener Kongresses behandeln die Artikel 66 bis 69 das Großherzogtum Luxemburg. Hier werden die Grenzen des neuen Staates allerdings nur grob umrissen; detaillierte Regelungen blieben späteren Verträgen vorbehalten. Unstrittig war die Süd- und Westgrenze mit Frankreich; sie entsprach der 1769/79 festgesetzten und bis 1795 gültigen Linie mit Ausnahme des ehemaligen Herzogtums Bouillon als Zugewinn. Vollkommen neu festgelegt wurde jedoch die Ostgrenze: Mit der Schlussakte des Wiener Kongresses waren alle hier an Luxemburg angrenzenden Gebiete an das Königreich Preußen gefallen. In den Verträgen von Aachen (26. Juni 1816) und Kleve (7. Oktober 1816) einigten sich die niederländische und die preußische Seite darauf, dass die Flussläufe von Mosel, Sauer und Our zukünftig die gemeinsame Grenze bildeten. Hier offenbart sich ein grundlegender Wandel im Verständnis und der Genese von Grenzen: Bisher waren territoriale Veränderungen auf Grundlage historisch gewachsener Herrschaftsstrukturen vorgenommen worden. So konnten kleinere Herrschaften aber auch größere Gebietskonglomerate zwar durch Tausch, Verkauf, Abtretung oder - wie durch Frankreich praktiziert - als „Reunionen“ die territoriale Zugehörigkeit wechseln. Dabei wurden jedoch die historisch gewachsenen Grenzen beachtet, sogar noch bei der Einrichtung der französischen Départements 1795. Mit der Wahl des Flußverlaufs von Sauer und Our als Grenze zwischen Luxemburg und Preußen wurde dieses Prinzip durchbrochen und ein naturräumliches Gliederungselement als neu geschaffene Grenze gewählt.

Malicious users can attack Web applications by exploiting injection vulnerabilities in the source code. This work addresses the challenge of detecting injection vulnerabilities in the server-side code of Java Web applications in a scalable and effective way. We propose an integrated approach that seamlessly combines security slicing with hybrid constraint solving; the latter orchestrates automata-based solving with meta-heuristic search. We use static analysis to extract minimal program slices relevant to security from Web programs and to generate attack conditions. We then apply hybrid constraint solving to determine the satisfiability of attack conditions and thus detect vulnerabilities. The experimental results, using a benchmark comprising a set of diverse and representative Web applications/services as well as security benchmark applications, show that our approach (implemented in the JOACO tool) is significantly more effective at detecting injection vulnerabilities than state-of-the-art approaches, achieving 98% recall, without producing any false alarm. We also compared the constraint solving module of our approach with state-of-the-art constraint solvers, using six different benchmark suites; our approach correctly solved the highest number of constraints (665 out of 672), without producing any incorrect result, and was the one with the least number of time-out/failing cases. In both scenarios, the execution time was practically acceptable, given the offline nature of vulnerability detection. [less ▲]

In this chapter, I discuss the interplay of urban theory and practice in the context of the science-policy interface: a space of mutual engagement of research and related practices in the urban arena. My case study analyses the work of the German Advisory Council on Global Change (Wissenschaftlicher Beirat der Bundesregierung Globale Umweltveränderungen, WBGU), most notably its 2016 report on global urbanisation (WBGU 2016). By presenting the big narrative of the planet becoming entirely urbanised, there is a certain positivism and essentialism underlying this report that fails to acknowledge political conflict and what went wrong in the past. This contradicts the lofty political ambitions of the advisory council. I conclude that the WGBU’s policy advice and consultation is limited because it does not consider the murky and messy nature of politics and, thus, does not provide sufficient orientation for practice. This case study therefore illustrates the difficulties and problems when research and practice interact. [less ▲]

This paper aims to design joint precoding and onboard beamforming of a multiple gateway multibeam satellite system, either in a hybrid space-ground mode, or in a totally on-board one. In such an architecture, with employing high throughput full frequency reuse pattern over both user and feeder links, each gateway serves a cluster of adjacent beams such that the adjacent clusters are served through a set of gateways that are located at different geographical areas. However, such a system brings in two challenges to overcome. First, the interference in both user and feeder links is the bottleneck of the whole system and applying interference mitigation techniques becomes necessary. Second, as the data demand increases, the ground and space segments should employ extensive bandwidth resources in the feeder link accordingly. This entails embedding an extra number of gateways aiming to support a fair balance between the increasing demand and the corresponding required feeder link resources. To solve these problems, this study investigates the impact of employing a joint multiple gateway architecture and on-board beamforming scheme. It is shown that by properly designing the on-board beamforming scheme, the number of gateways can be kept affordable even if the data demand increases. Moreover, Zero Forcing (ZF) precoding techniques are considered to cope with the interference in both user and feeder links which embed in the following premises: (i) each gateway constructs a part of block ZF precoding matrix, (ii) the satellite and gateways perform the precoding scheme, and (iii) a joint design of ZF precoding and on-board beamforming at the payload of the satellite so that no signal processing scheme is conceived at the gateways. The provided simulation results depict the performance gain obtained by our proposed schemes. [less ▲]

Attention plays a pivotal role in the experience of pain and its impact upon daily activities. Accordingly, research on the interplay between attention and pain has a long scientific history. Within this chapter, we discuss the theoretical frameworks that aim to explain the relationship between attention and pain. We argue for a motivational perspective on pain that highlights the critical role of cognitive, affective and contextual factors in explaining the interplay between attention and pain. To substantiate this argument, we provide an overview of available research addressing the bottom-up capture of attention by pain and the top-down modulation (both inhibition and facilitation) of attention for pain. We conclude this chapter with guidelines and suggestions for future research and discuss clinical implications of adopting a motivational perspective on pain. [less ▲]

Although student self-assessment is positively related to achievement, skepticism about the accuracy of students’ self-assessments remains. A few studies have shown that even elementary school students are able to provide accurate self-assessments when certain conditions are met. We developed an innovative tablet-computer-based tool for capturing self-assessments of mathematics and reading comprehension. This tool integrates the conditions required for accurate self-assessment: (1) a non-competitive setting, (2) items formulated on the task level, and (3) limited reading and no verbalization required. The innovation consists of using illustrations and a language-reduced rating scale. The correlations between students’ self-assessment scores and their standardized test scores were moderate to large. Independent of their proficiency level, students’ confidence in completing a task decreased as task difficulty increased, but these findings were more consistent in mathematics than in reading comprehension. We conclude that third- and fourth-graders have the ability to provide accurate self-assessments of their competencies, particularly in mathematics, when provided with an adequate self-assessment tool.
