Der Beitrag erinnert an das wechselvolle Leben des Friedensnobelpreisträgers Henry Dunant, sucht nach biografischen Wurzeln seines von Menschlichkeit und Würde getragenen Verhaltens und macht auf seine Leistungen aufmerksam. Er will aber auch die Frage nach der Bedeutung des humanitären Völkerrechts im Verhältnis von Krieg und Frieden nicht außer Acht lassen.
Deductive databases need general formulas in rule bodies, not only conjuctions of literals. This is well known since the work of Lloyd and Topor about extended logic programming. Of course, formulas must be restricted in such a way that they can be effectively evaluated in finite time, and produce only a finite number of new tuples (in each iteration of the TP-operator: the fixpoint can still be infinite). It is also necessary to respect binding restrictions of built-in predicates: many of these predicates can be executed only when certain arguments are ground. Whereas for standard logic programming rules, questions of safety, allowedness, and range-restriction are relatively easy and well understood, the situation for general formulas is a bit more complicated. We give a syntactic analysis of formulas that guarantees the necessary properties.
This paper is a critical examination of the relationship between reality and simulation. After a brief theoretical introduction, it unfolds its argument on an empirical level, using a thick game playing description of GRAND THEFT AUTO IV. This in-game experience serves as material for the subsequent analysis, in the course of which defining characteristics of computer game playing are formulated. Finally, on the basis of this analysis, the paper postulates the hypothesis that playing computer games like GTA IV promotes competency in deconstructing simulations and implements a cyclic logic of recreation.
Because software development is increasingly expensive and timeconsuming, software reuse gains importance. Aspect-oriented software development modularizes crosscutting concerns which enables their systematic reuse. Literature provides a number of AOP patterns and best practices for developing reusable aspects based on compelling examples for concerns like tracing, transactions and persistence. However, such best practices are lacking for systematically reusing invasive aspects. In this paper, we present the ‘callback mismatch problem’. This problem arises in the context of abstraction mismatch, in which the aspect is required to issue a callback to the base application. As a consequence, the composition of invasive aspects is cumbersome to implement, difficult to maintain and impossible to reuse. We motivate this problem in a real-world example, show that it persists in the current state-of-the-art, and outline the need for advanced aspectual composition mechanisms to deal with this.
In this paper we consider a simple syntactic extension of Answer Set Programming (ASP) for dealing with (nested) existential quantifiers and double negation in the rule bodies, in a close way to the recent proposal RASPL-1. The semantics for this extension just resorts to Equilibrium Logic (or, equivalently, to the General Theory of Stable Models), which provides a logic-programming interpretation for any arbitrary theory in the syntax of Predicate Calculus. We present a translation of this syntactic class into standard logic programs with variables (either disjunctive or normal, depending on the input rule heads), as those allowed by current ASP solvers. The translation relies on the introduction of auxiliary predicates and the main result shows that it preserves strong equivalence modulo the original signature.
Communication, simulation, interactive narrative and ubiquitous computing are widely accepted as perspectives in humancomputer interaction. This paper proposes play as another possible perspective. Everyday uses of the computer increasingly show signs of similarity to play. This is not discussed with regard to the so-called media society, the playful society, the growing cultural acceptance of the computer, the spread of computer games or a new version of Windows, but in view of the playful character of interaction with the computer that has always been part of it. The exploratory learning process involved with new software and the creative tasks that are often undertaken when using the computer may support this argument. Together with its high level of interactivity, these observations point to a sense of security, autonomy and freedom of the user that produce play and are, in turn, produced by play. This notion of play refers not to the playing of computer games, but to an implicit, abstract (or symbolic) process based on a certain attitude, the play spirit. This attitude is discussed regarding everyday computer use and related to the other mentioned perspectives.

The issue of determining the time, when the Judaic communities have settled on Romanian land, is one of the most interesting and most delicate details that can be mentioned when talking about this ethnic group. The presence of the first Jewish communities in ancient times on this land was a “taboo” subject during many historical periods until 1989, but even after this year, studies oriented in this direction were more than sketchy. The article does not only bring a surplus of information in this domain, but manages to concentrate – almost didactically – the information and the archaeological proofs known and reknown to the present time. There are depicted material evidences as well as linguistic ones, toponymical and even religious. Also, the author tries to draw a parallel between some layouts of the Dacian state and Dacia Felix, conquered by the Romans, and the presence of some Judaic communities, not very numerous, made out of Judaic population who came together with the Roman conqueror.

Die sich zunächst um Griechenland rankende Krise wurde zu einer europäischen, die den Euro bedroht. Allenthalben wird die Frage gestellt: Wer ist schuld? In deutschen Groß-Medien wird auf das Zögern der derzeitigen Bundesregierung verwiesen. Der Euro rutschte in die Gefahrenzone. Aber ist der Verweis auf falsche Politik die Antwort auf die Frage nach dem erneuten Aufbrechen der Finanzkrise?
