Very large scale systems of autonomous concurrent objects (Actors) require coordination models to meet two competing goals. On the one hand, the coordination models must allow Actors to dynamically modify protocols in order to adapt to requirement changes over the, likely extensive, lifetime of the system. On the other hand, the coordination models must enforce protocols on potentially uncooper...

We studied perception of affordances for the actions of other persons (actors) from kinematic displays. Observers judged the maximum and preferred sitting heights of tall and short actors. Judgments were scaled in centimeters, as a proportion of the observer’s leg length, and as a proportion of each actor’s leg length. Only when judgments were scaled by actor leg length did they reflect the act...

This article discusses the cognitive plausibility of actors or agents within transaction cost economics (TCE). Our main thesis is that, although the actors within TCE are not based on cognitive functions, a simulation model can be built in which the cognition of the actors is accounted for. In this article we want to discuss four things. In the first place we describe TCE and its actors in whic...

New technologies and systems are greatly impacting people’s lives. However, innovation has the potential to bring benefits as well as threats. In this world of technical revolution we argue that in order to arrive at proper systems requirements, one should examine and understand the relationships among social actors. Rather than focusing of behavioral properties of the software, we should ask h...

Wireless sensor and actor networks (WSANs) consist of powerful actors and resource constraint sensors that are linked together in wireless networks. They mostly rely on actors to make proper decisions and perform desired coordination to achieve the goals of the entire network. They are usually deployed in critical applications and actor-actor network connectivity is thus vital to their effectiv...

This paper presents techniques and tools for creating and animating virtual actors in real scenes. Several problems are explained: real objects hidden by virtual actors and virtual actors hidden by real objects, collision detection between the virtual actor and the real environment, correspondence between the real and the virtual cameras, casting shadows of the virtual actors on the real world....

the present research aims to investigate and rank which affect and re affected by employees’ psychological empowerment in order to help organizations and their employees to be more committed to their jobs by accessing resources and feeling control and ownership and use initiative in their works in order to do works well so that their effectiveness and efficiency within organization will be impr...

This paper presents the use of Virtual Reality (VR) for movie actors rehearsal of VFX-enhanced scenes. The impediment behind VFX scenes is that actors must be filmed in front of monochromatic green or blue screens with hardly any cue to the digital scenery that is supposed to surround them. The problem is worsens when the scene includes interaction with digital partners. The actors must pretend...

Political actors sometimes make public commitments not to negotiate with other actors whom they label as being beneath diplomacy. Interestingly, such commitments are sometimes made even as they are being broken. Why do actors sometimes publicly denounce adversaries with whom they intend to negotiate? What factors influence actors’ incentives to label adversaries in one way as opposed to another...
