Sprache, Identität, Politik und Schule stehen bekanntlich in enger Verbindung (Bourdieu und Passeron 1970). Ein besonders eindrucksvolles Beispiel für die enge Vernetzung dieser gesellschaftlichen Bereiche stellt das Großherzogtum Luxemburg dar. Seit dem Mittelalter werden auf dem Territorium des heutigen Luxemburg verschiedene Sprachen verwendet, vor allem Deutsch, Französisch und dialektale Varietäten des Luxemburgischen, das 1984 zu einer eigenständigen Nationalsprache erklärt wurde.

Seit nunmehr 100 Jahren ist das heutige Ostbelgien Teil des Belgischen Königreichs. Diesen Jahrestag haben die beiden Historiker Christoph Brüll und Andreas Fickers zum Anlass genommen, gemeinsam mit dem BRF in 8 Radioessays in die ostbelgische Vergangenheit hineinzuhorchen. Die bislang kaum erforschten Tonarchive des BRF haben sich als herausragende Quelle erwiesen, um Zwischentöne hörbar zu machen und so Stimmen und Stimmungen aus der bewegten ostbelgischen Vergangenheit wieder zu beleben. Die in diesem Band versammelten Sendemanuskripte bieten keine ostbelgische Chronik. Vielmehr sollen sie zum Nachdenken über Geschichte anregen, darüber, wie historische Deutungen entstehen und auch, warum es sich lohnt, sich mit der Geschichte des ostbelgischen Zwischenraums als europäische Geschichte en miniature zu beschäftigen.

In recent years, smart contracts have suffered major exploits, cost- ing millions of dollars. Unlike traditional programs, smart contracts are deployed on a blockchain. As such, they cannot be modified once deployed. Though various tools have been proposed to detect vulnerable smart contracts, the majority fails to protect vulnera- ble contracts that have already been deployed on the blockchain. Only very few solutions have been proposed so far to tackle the issue of post-deployment. However, these solutions suffer from low precision and are not generic enough to prevent any type of attack. In this work, we introduce ÆGIS, a dynamic analysis tool that protects smart contracts from being exploited during runtime. Its capability of detecting new vulnerabilities can easily be extended through so-called attack patterns. These patterns are written in a domain-specific language that is tailored to the execution model of Ethereum smart contracts. The language enables the description of malicious control and data flows. In addition, we propose a novel mechanism to streamline and speed up the process of managing attack patterns. Patterns are voted upon and stored via a smart contract, thus leveraging the benefits of tamper-resistance and transparency provided by the blockchain. We compare ÆGIS to current state-of-the-art tools and demonstrate that our solution achieves higher precision in detecting attacks. Finally, we perform a large-scale analysis on the first 4.5 million blocks of the Ethereum blockchain, thereby confirming the occurrences of well reported and yet unreported attacks in the wild.

In recent years, smart contracts have suffered major exploits, losing millions of dollars. Unlike traditional programs, smart contracts cannot be updated once deployed. Though various tools were pro- posed to detect vulnerable smart contracts, they all fail to protect contracts that have already been deployed on the blockchain. More- over, they focus on vulnerabilities, but do not address scams (e.g., honeypots). In this work, we introduce ÆGIS, a tool that shields smart contracts and users on the blockchain from being exploited. To this end, ÆGIS reverts transactions in real-time based on pat- tern matching. These patterns encode the detection of malicious transactions that trigger exploits or scams. New patterns are voted upon and stored via a smart contract, thus leveraging the benefits of tamper-resistance and transparency provided by blockchain. By allowing its protection to be updated, the smart contract acts as a smart shield. [less ▲]

Hannsjörg Voth produces with the evident necessity of high physical endurance art projects with mythical and utopian contents. The creations of the artist touch so many artistic domains that it is not possible to attach him to a single typology of art expression. The present research features an analyze and an interpretation of Voths’ artwork in the setting of his personal artistic evolution. In his creative approach, the methodical progress to accomplish what is called in this research an art project, is studied in all its sequences in order to define in a more clear way this new artistic expression. It tries not only to overcome the traditional supports but also includes modern medias, so as photos and videos as integral and essential parts of the artists’ works. A confrontation with the art of the past and simultaneously contemporary creative expressions allows to better define the art coordinates of Voth and to give an evaluation of originality and artistic quality in the context of countless aesthetic forms that represent visual arts at the end of the XXth century.

Parkinson’s disease (PD) comprises a spectrum of disorders with differing subtypes, the vast majority of which share Lewy bodies (LB) as a characteristic pathological hallmark. The process(es) underlying LB generation and its causal trigger molecules are not yet fully understood. α-Synuclein (α-syn) is a major component of LB and SNCA gene missense mutations or duplications/triplications are causal for rare hereditary forms of PD. As typical sporadic PD is associated with LB pathology, a factor of major importance is the study of the α-syn protein and its pathology. α-Syn pathology is, however, also evident in multiple system atrophy (MSA) and Lewy body disease (LBD), making it non-specific for PD. In addition, there is an overlap of these α-synucleinopathies with other protein-misfolding diseases. It has been proven that α-syn, phosphorylated tau protein (pτ), amyloid beta (Aβ) and other proteins show synergistic effects in the underlying pathogenic mechanisms. Multiple cell death mechanisms can induce pathological protein-cascades, but this can also be a reverse process. This holds true for the early phases of the disease process and especially for the progression of PD. In conclusion, while rare SNCA gene mutations are causal for a minority of familial PD patients, in sporadic PD (where common SNCA polymorphisms are the most consistent genetic risk factor across populations worldwide, accounting for 95% of PD patients) α-syn pathology is an important feature. Conversely, with regard to the etiopathogenesis of α-synucleinopathies PD, MSA and LBD, α-syn is rather a bystander contributing to multiple neurodegenerative processes, which overlap in their composition and individual strength. Therapeutic developments aiming to impact on α-syn pathology should take this fact into consideration. [less ▲]
