We study the role of imitation within a model of economics with adaptive agents. The basic ingredients are those of the Minority Game. We add the possibility of local information exchange and imitation of the neighbour’s strategy. Imitators should pay a fee to the imitated. Connected groups are formed, which act as if they were single players. Coherent spatial areas of rich and poor agents resu...

Voice imitation is one of the potential threats to security systems that use automatic speaker recognition. Since prosodic features have been considered for state-of-the-art recognition systems in recent years, the question arises as to how vulnerable these features are to voice mimicking. In this study, two experiments are conducted for twelve individual features in order to determine how a pr...

In this paper we describe an experiment aimed at determining the most effective and natural orientation of a virtual guide that gives route directions in a 3D virtual environment. We hypothesized that, due to the presence of mirrored gestures, having the route provider directly face the route seeker would result in a less effective and less natural route description than having the route provid...

Erythema multiforme (EM) is an uncommon, immune-mediated disorder that presents with cutaneous or mucosal lesions or both. In herpes simplex virus (HSV)-associated EM, the findings are thought to result from cell-mediated immune reaction against viral antigen-positive cells that contain the HSV DNA polymerase gene (pol). The target lesion, with concentric zones of color change, represents the c...

While millions of users feel pity for the removal of Flappy Bird, many Flappy Bird copycats are flowing into the mobile app stores and even rocket up the top rank charts. In the highly competitive mobile app stores, imitating the names of “superstar” apps is a tactic shared by developers. In this paper, we examine the effects of this strategy – how and to what extent it influences the imitator ...

Problem-Based Learning (PBL) is a popular approach to instruction that supports students get hands-on training by solving problems. Question Pool websites (QPs) such as LeetCode, Code Chef, and Math Playground help PBL supplying authentic, diverse, contextualized questions students. Nonetheless, empirical findings suggest 40% 80% of registered in QPs drop out less than two months. This research...

In this paper we study the adaptive behavior of rms which repeatedly have to make strategic production decisions. In a single good market the rms use own experience as well as information gathered by observing competitors to iteratively choose a technology out of a given set. The adaptive learning of the rms is analyzed in a dynamic model formally resembling the so called 'Ant System'. In sever...
