À la veille d'une journée de "deuil absolu" pour l'anniversaire des attentats tragiques de Madrid du 11 mars 2004, afin de lutter contre le terrorisme, l'ancien secrétaire général de l'ONU, Kofi Annan, a proposé une stratégie globale respectueuse des droits de l'homme et de la primauté du droit. Cependant, la stratégie prévue par l'ONU ne semble s'adresser qu’aux pays dans lesquels l'arsenal juridique contient déjà une protection des droits de l'homme, car toutes les résolutions adoptées appellent les États à ne pas restreindre les droits de l'homme au nom de la lutte contre le terrorisme. Le problème en Irak est cependant beaucoup plus grave. En effet, la protection des droits fondamentaux y est encore lacunaire du fait de la genèse d’un système démocratique naissant et ajouté à cela, la dangerosité du terrorisme le plus brutal. L'importance croissante de la protection des droits de l'homme dans ce pays tient au fait que celle-ci représente un havre de paix pour calmer la brouille qui nourrit le terrorisme entre les diverses communautés de ce pays. Il s’agit essentiellement d’instaurer un climat favorable à une conciliation nationale. La lutte contre le terrorisme en Irak ne peut ainsi porter ses fruits sans l’adoption d’un État de droit et d’une loi qui affronte ce phénomène tout en conservant les droits fondamentaux. De même, depuis 2003, en dépit du fait que l’ONU et les nouveaux dirigeants s’efforcent d’ancrer les notions des droits de l’homme dans la société irakienne, leur tâche semble encore très difficile. En effet, l’échec continu de la communauté internationale dans ses diverses tentatives destinées à formuler une définition unanime du terrorisme s’est reflété négativement sur l’Irak. Le manque d’une définition juridique a permis à certaines puissances mondiales d’en donner une définition politique afin de servir leurs propres intérêts dans le cas irakien, ce qui a provoqué des violations des droits de l’homme au nom de la lutte contre le terrorisme en Irak, en entravant les étapes vers une considération efficace des droits fondamentaux. / On the eve of a day of ‘absolute mourning’ for the anniversary of the tragic attacks in Madrid on March 11th, 2004, in order to fight against terrorism, former UN Secretary General Kofi Annan proposed a comprehensive strategy respectful of human rights and the rule of law. However, the UN strategy seems to be addressed solely to countries in which the legal arsenal already contains a protection against human rights, as all the adopted resolutions call on states not to restrict human rights in the name of the fight against terrorism.The problem in Iraq is however much more serious. Indeed, the protection of fundamental rights in this country is still incomplete due to the genesis of a nascent democratic system, as well as to the dangerousness of the most brutal terrorism. The growing importance of the protection of human rights in this country is that the latter represents a haven of peace to calm the quarrel upon which terrorism thrives, between the different communities of this country. It is essentially a question of enabling a positive climate for a national conciliation.The fight against terrorism in Iraq cannot therefore bear fruit without a rule of law and a law which confront this phenomenon while maintaining fundamental rights. Similarly, since 2003, despite the fact that the UN and the new leaders have been striving to give a foothold to the concepts of human rights in the Iraqi society, the task still seems very difficult. Indeed, the continued failure of the international community in its various attempts to formulate a unanimous definition of terrorism was reflected negatively on Iraq. The lack of a legal definition allowed some world powers to establish a political definition in order to serve their own interests in the Iraqi case, which has caused violations of human rights in the name of the fight against terrorism in Iraq, by impeding the steps towards effective respect for fundamental rights.

The Alexander romance—a heroic narrative loosely based on the life of Alexander the Great—was one of the most widely copied texts throughout premodern Europe and the Islamic world. In premodern Persian histories and literature, Alexander was an archetypal Persian king, who conquered the world and united "East and West." Four Persian Alexander epics were composed between 1000 and 1500 CE by some of the most famous authors of the Persian literary tradition: Firdausi (d.1020), Nizami (d.1209), Amir Khusrau (d.1325) and Jami (d.1492). Despite the importance of these epics to premodern Persian literature, this dissertation is the first monograph in any European language to compare all four canonical versions of the Persian Alexander epic in depth. My analysis focuses on the ways in which Persian Alexander epic tradition provides insight into the development of the Persian cosmopolis, a trans-regional cultural phenomenon extending from the Balkans to the Bay of Bengal.

After the defeat of the Greek forces in the Lamian War the Athenians agreed to Antipater's demand for unconditional surrender. As result of the terms the Macedonian general demanded Phocion became pre-eminent in Athens for a few years from 322/1 to 319/8 B.C. It is my belief that, although he did not seek to become leader in Athens, Phocion none-the-less accepted his new role out of a sense of duty and a firm belief that he was the only person suited for the job. Here was a man whose logical, pragmatic and unemotional attitude to political and world affairs enabled him to rise above what he believed to be the short-sightedness of his contemporaries and accurately assess the future for Athens and the city-state's place in the new world order. Of course our picture of Phocion is taken, mainly, from Plutarch's encomiastic Life of Phocion. According to his account the Athenian general and statesman did not want war but peace and prosperity. He did not believe the Athenians capable of defeating Macedonia. Instead, he felt that the people should accept their new position in the world and make the best of the situation. It should not be forgotten, however, that Plutarch was writing at a time when Europe was under the yoke of the new superpower: Rome. He saw the benefits of living in Greece at a time when the city-states were no longer continually involved in internecine warfare. It was, perhaps, this appreciation of the state of his own world, gained with the benefit of hindsight, that gave rise to his admiration of (what he perceived to be) Phocion's foresight. Phocion appeared to understand, as Plutarch did, that there was no reason why Athens could not still be prosperous. Plutarch's Phocion saw the city-state's future as no longer being primarily reliant on military preparedness but rather on trade and sound economic policy. With the protection of the powerful Macedonian overlord Athens would be free to enjoy life in relative peace and prosperity. Ultimately, Plutarch has had a significant influence on our understanding and appreciation of Phocion the general, statesman and man. The aim of this paper then is, with the use of other primary and secondary sources, to look beyond Plutarch's encomium and attempt to find the real Phocion. In particular, I will be examining the aging general's role in Athenian affairs after the Lamian War. This pivotal time in Athenian history has received too little attention. Life in Athens changed dramatically after Antipater defeated the Greek forces at the Battle of Crannon. The Athenians lost their freedom and autonomy and were fated never to regain the hegemony of the Greeks. Moreover, they had failed to live up to the glorious deeds of their ancestors. It was Phocion's task to help his people to come to terms with this new state of affairs and to find a place for Athens in the new world order. And so, political life in Athens was turned upside down as democracy was changed to oligarchy.

Dreidimensionale Informationsvisualisierungen fördern durch den geringen Grad an Abstraktion die Bildung eines präzisen mentalen Modells und können daher multidimensionale räumliche Beziehungen greifbar kommunizieren. Gleichzeitig eröffnet die aktuelle Generation von Augmented Reality Head-Mounted Displays (AR-HMDs) neuartige Möglichkeiten zur Exploration von 3D-InfoVis und ist befähigt virtuelle Objekte glaubwürdig und immersiv in die physische Umgebung eines Nutzers zu integrieren. Dennoch unterliegt die Interaktion in AR-Umgebungen einer Vielzahl von Herausforderungen, da die signifikante Mehrheit der Applikationen lediglich Blick-, Freihandgesten- oder Sprachsteuerung als Eingabemodalität in Betracht ziehen. Durch Kombination von interaktiven Oberflächen wie Tabletops mit AR-HMDs können diese Nachteile effizient adressiert werden, indem direkte und natürliche Manipulation in Form von Multi-Touch, Tangible- oder Stift-Eingabe ermöglicht wird. Im Rahmen dieser Thesis wird untersucht, wie die Analyse von 3D-InfoVis bei Kombination interaktiver Oberflächen mit AR-HMDs unterstützt werden kann. Hierfür wird der aktuelle Stand der Forschung in themennahen Domänen erfasst und folgend Konzepte zur Unterstützung analytischer Prozesse in zuvor erläuterter Systemkonstellation entwickelt. Die resultierenden Konzepte adressieren dabei Limitationen, die bei Darstellung und Interaktion von und mit 3D-InfoVis in konventionellen Systemen bestehen und im Rahmen der Kombination interaktiver Oberflächen mit AR-HMDs gelöst oder wesentlich angereichert werden können. Ausgewählte Features wurden in einer prototypischen Implementierung realisiert und getestet. / Three-dimensional information visualizations aid precise mental models and are able to communicate multidimensional-spatial relations due too their low level of abstraction. Simultaneously the current generation of Augmented Reality head-mounted displays (AR-HMDs) are offering novel chances for the exploration of 3D-InfoVis and are capable of immersively integrating virtual object into the physical environment of a user. Nevertheless, interaction in AR-environments is still posing a major challenge due to most applications only considering gaze, freehand gesture or speech as input modalities. By combining AR-HMDs with interactive surfaces these limitations can be addressed and direct and natural interaction in the form of multi-touch-, tangible- or pen-input can be enabled. In the scope of this thesis it will be examined how the analysis of 3D-InfoVis can be supported in the context of combining interactive surfaces with AR-HMDs. Therefor the current state of research in associated domains is being summarized and based on that concepts for supporting analytical processes in aforementioned system constellation are being developed. The resulting concepts help addressing limitations, that exist in the representation and interaction of and with 3D-InfoVis in conventional systems in the scope of combining interactive surfaces with AR-HMDs in order to overcome them or reduce their effects. Selected features were implemented and tested in a prototype.

Projektet har till syfte att undersöka den revolutionerande tekniken bakom IP-telefoni. Eftersom tekniken är relativt ung så finns det fortfarande mycket att lära om hur det fungerar och hur den används. Projektet behandlar fördelar och nackdelar samt vilka hot som finns och hur man kan känna sig säker när man använder IP-telefoni till vardags. Det primära objektivet med projektet är att få en helhetsbild och förstå hur tekniken verkligen fungerar. Vidare behandlas telefonens historia då det är viktigt att se var tekniken har sina rötter och hur den utvecklats sedan dess. Som en röd tråd från telefonens teknologi och det publika telefonnätets rötter görs en jämförelse mellan de två teknologierna för att se skillanderna och förmodade fördelar och nackdelar med de båda systemen. Olika sorters protokoll som har ett nära förhållande till IP-telefoni så som SIP, RTP, UDP och IP behandlas. För att få en sanningsenlig bild över hur vardagliga användare upplever IP-telefoni så har en enkätundersökning angående vanor och möjliga problem gjorts hos de anställda på Region Skåne.
