In a much-cited recent article, Obermeyer, Murray, and Gakidou (2008a) examine estimates of wartime fatalities from injuries for thirteen countries. Their analysis poses a major challenge to the battle-death estimating methodology widely used by conflict researchers, engages with the controversy over whether war deaths have been increasing or decreasing in recent decades, and takes the debate o...

Reasoning on the properties of computer systems can often be reduced to deciding the winner of a game played on a finite graph. In this paper, we introduce GAVS, an open-source tool for the visualization of some of the most fundamental games on finite graphs used in theoretical computer science, including, e.g., reachability games and parity games. The main purpose of GAVS is educational, a fac...

Geometric alterations to the boundaries of a virtual environment were used to investigate the representations underlying human spatial memory. Subjects encountered a cue object in a simple rectangular enclosure, with distant landmarks for orientation. After a brief delay, during which they were removed from the arena, subjects were returned to it at a new location and orientation and asked to m...

Wheeler’s Superspace is the arena in which Geometrodynamics takes place. I review some aspects of its geometrical and topological structure that Wheeler urged us to take seriously in the context of canonical quantum gravity. PACS 04.60.-m · 04.60.Ds · 02.40.-k Mathematics Subject Classification (2000) 83C45 · 57N10 · 53D20 “The stage on which the space of the Universe moves is certainly not spa...

Arena is a software package intended to help e-commerce strategy researchers and designers test buying and selling strategies under different scenarios. It implements and adheres to a set of design criteria intended to ensure its simulation ability as well as prolonging its usable lifetime. The process of implementing Arena involved conducting background research into current strategies and the...

Robotics was introduced by Danbury Pharmacal, Inc. in 1987 in order to improve laboratory throughput for several new products. The author uses Danbury Pharmacal's experience to give an overview of various issues, such as acceptance by senior management and chemists, political confrontation, validation and product throughput.

European Journal of Information Systems (2011) 20, 251–254. doi:10.1057/ejis.2011.8; published online 22 March 2011 Evolution is what happens when you are not watching. An example is the personal computer. Computing for many individual persons has evolved from the ‘standalone desktop PC’ to a ‘networked PC’ to a ‘network of a PC and a laptop’ to a ‘network of PCs, laptops, printers, smartphones...

This paper argues that anticipatory standardization can be viewed as an arena for open innovation and shows this through two cases from mobile telecommunication standardization. One case is the Android initiative by Google and the Open Handset Alliance, while the second case is the general standardization work of the Open Mobile Alliance. The paper shows how anticipatory standardization intenti...

In last years all the activities developed in the cultural heritage field have shown the necessity to integrate different analytical methodologies and technologies to obtain a cognitive apparatus of our architectural monuments, both from geometric and materical-

The development of targeted gene repair is under way and, despite some setbacks, shows promise as an alternative form of gene therapy. This approach uses synthetic DNA molecules to activate and direct the cell's inherent DNA repair systems to correct inborn errors. The progress of this technique and its therapeutic potential are discussed in relation to the treatment of genetic diseases.
