Shakespearean Histories and Greek History: Henry V and Richard II at the Greek National Theatre (1941, 1947)

Henry V and Richard II made their first and only appearance on the Greek stage in the turbulent 1940s. The first was performed in March 1941, just before the arrival of the German nazis, and the second in November 1947, a year after the problematic referendum on the future of the Greek monarchy and in the midst of the Greek civil war. The producer in both times was the state-funded National Theatre of Greece. The article argues that the national stage appropriated these plays in order to influence public sentiment about current historical events (World War II and restoration of monarchy), but it failed to make an impact in either case. The reasons for the failure are traced in the interrelationship of historical context, staging style, and audience needs

Online privacy: towards informational self-determination on the internet : report from Dagstuhl Perspectives Workshop 11061

The Dagstuhl Perspectives Workshop "Online Privacy: Towards Informational Self-Determination on the Internet" (11061) has been held in February 6-11, 2011 at Schloss Dagstuhl. 30 participants from academia, public sector, and industry have identified the current status-of-the-art of and challenges for online privacy as well as derived recommendations for improving online privacy. Whereas the Dagstuhl Manifesto of this workshop concludes the results of the working groups and panel discussions, this article presents the talks of this workshop by their abstracts

Intrusion Prevention and Detection in Wireless Sensor Networks

The broadcast nature of the transmission medium in wireless sensor networks makes information more vulnerable than in wired applications. In this dissertation we first propose a distributed, deterministic key management protocol designed to satisfy authentication and confidentiality, without the need of a key distribution center. Next we propose Scatter, a secure code authentication scheme for efficient reprogramming sensor networks. Scatter avoids the use of Elliptic Key Cryptography and manages to surpass all previous attempts for secure code dissemination in terms of energy consumption and time efficiency. Next we introduce the problem of intrusion detection in sensor networks. We define the problem formally based on a generic system model and we prove a necessary and sufficient condition for successful detection of the attacker. Finally we present the architecture and implementation of an intrusion detection system which is based on a distributed architecture and it is lightweight enough to run on the nodes

Evolutionary Signatures of Common Human Cis-Regulatory Haplotypes

Variation in gene expression may give rise to a significant fraction of inter-individual phenotypic variation. Studies searching for the underlying genetic controls for such variation have been conducted in model organisms and humans in recent years. In our previous effort of assessing conserved underlying haplotype patterns across ethnic populations, we constructed common haplotypes using SNPs having conserved linkage disequilibrium (LD) across ethnic populations. These common haplotypes cluster into a simple evolutionary structure based on their frequencies, defining only up to three conserved clusters termed ‘haplotype frameworks’. One intriguing preliminary finding was that a significant portion of reported variants strongly associated with cis-regulation tags these globally conserved haplotype frameworks. Here we expand the investigation by collecting genes showing stringently determined cis-association between genotypes and expression phenotypes from major studies. We conducted phylogenetic analysis of current major haplotypes along with the corresponding haplotypes derived from chimpanzee reference sequences. Our analysis reveals that, for the vast majority of such cis-regulatory genes, the tagging SNPs showing the strongest association also tag the haplotype lineages directly separated from ancestry, inferred from either chimpanzee reference sequences or the allele frequency-derived haplotype frameworks, suggesting that the differentially expressed phenotypes were evolved relatively early in human history. Such evolutionary signatures provide keys for a more effective identification of globally-conserved candidate regulatory haplotypes across human genes in future epidemiologic and pharmacogenetic studies
