Dario Floreano’s review of Robot Shaping: An Experiment in Behavior Engineering is very stimulating, and would deserve a long answer. However, we do not want to abuse our right to the last word which the editor of this special issue accorded to us. Therefore, we shall limit our reply to a few points: (i) the relatively high learning time required by our system, (ii) the urge for more sophistica...

In this study, we examine how business units of multidivisional (M-form) firms adapt their activities in response to poor performance at the corporate and business unit levels. By linking performance feedback theory with theories of attention and M-form organizations, we show that corporate structure influences the relationship between performance below aspirations and business unit adaptation....

In this paper we name some of the advantages of virtual laboratories; and propose that a Behaviours Virtual Laboratory should be useful for both biologists and AI researchers, offering a new perspective for understanding adaptive behaviour. We present our development of a Behaviours Virtual Laboratory, which at this stage is focused in action selection, and show some experiments to illustrate t...

We study the adaptive behavior of a computational ecosystem in the presence of time-periodic resource utilities as seen, for example, in the day–night load variations of computer use and in the price fluctuations of seasonal products. We do so within the context of the Huberman-Hogg model of such systems. The dynamics is studied for the cases of competitive and cooperative payoff functions with...

Dexterous action, as conceptualized by Bernstein in his influential ecological analysis of human behavior, is revealed in the ability to flexibly generate behaviors that are adaptively tailored to the demands of the context in which they are embedded. Conceived as complex adaptive behavior, dexterity depends upon the qualities of robustness and degeneracy, and is supported by the functional com...

Background: Diabetes is a stressful condition, which affects identity and psychosocial dimensions in adolescent then they need to be adapted. This study was conducted to investigate the effect of spiritual care on adolescents' adjustment with Type 1 diabetes. Materials and Methods: This randomized controlled clinical trial study was performed on 52 adolescents with Type 1 diabetes mellitus memb...

In this paper, we introduce a new hyperchaotic complex T-system. This system has complex nonlinear behavior which we study its dynamical properties including invariance, equilibria and their stability, Lyapunov exponents, bifurcation, chaotic behavior and chaotic attractors as well as necessary conditions for this system to generate chaos. We discuss the synchronization with certain and uncerta...

Dynamically Adaptive Systems (DASs) adjust their behaviour at runtime to tolerate changes in context. With potentially incomplete or inaccurate knowledge of an operating environment, tailoring specific behavioural adjustments to individual contextual changes is a time-consuming and errorprone process. i* models of a DAS' behavioural adjustments can aid understanding, and can form part of the sp...

Web portals contain large amount of information. Users could really benefit from it if personalized presentation is used. For this to be accomplished the website needs to “know” its users. When surfing the Web users leave digital footprints in the form of navigational paths and actions taken. We present a method for adaptive navigation support and link recommendation. The method is based on an ...
