Organizational politics is an important determinant in the pay systems based on performance evaluation as both supervisors and subordinates have a possibility to affect the results of the appraisal process. Sometimes supervisors might be tempted to manipulate ratings in order to influence the behavior of their subordinates or even to affect their own position in the organization. The main chara...

The efficiency of service discovery in distributed systems relies on the collaboration of the agents and the structure of the relations established among them. Structural relations cannot be static, agents should be able to adapt their links as the domain conditions and their interests change. This self-organization considerably improves the performance of the service discovery process. We pres...

Patients are entitled to know about their dental and oral health, and practitioners have an ethical duty to inform them on an honest and factual basis. If this can be done without denigrating one's colleagues in any way, both patients and practitioners can benefit. As professionals, our first obligation is to place the well-being of our patients ahead of our own interests. First and foremost an...

One of the long-term goals of artificial life research is to create autonomous, self-motivated, and intelligent animats. We study an intrinsic motivation system for behavioral self-exploration based on the maximization of the predictive information using the Stumpy robot, which is the first evaluation of the algorithm on a real robot. The control is organized in a closed-loop fashion with a rea...

In this paper, we develop a Bayesian evidence maximization framework to solve the sparse non-negative least squares problem (S-NNLS). We introduce a family of scale mixtures referred as to Rectified Gaussian Scale Mixture (RGSM) to model the sparsity enforcing prior distribution for the signal of interest. Through proper choice of the mixing density, the R-GSM prior encompasses a wide variety o...
