Opis:
Personnel selection is a strategic decision in knowledge-intense enterprises. Choosing the right qualified labor is crucial for IT companies. While evaluating the possible candidates for required positions, many aspects should be considered, such as technical skills, individual skills, etc. Multi-criteria decision making methods give supportive solutions for problems involving multi-dimensional human judgment. Human decisions mostly exhibit gradual judgment, vagueness and imprecision. Fuzzy set theory is a fundamental tool to develop models with uncertainty and relativity. This study aims to build a fuzzy analytical hierarchy process method for personnel selection in IT companies. A case study in a spin-off IT company in Sakarya University, Technology Development Zone was conducted to acquire empirical evidence. Furthermore the proposed study provides a decision support system for human resource departments to relax personnel selection problem.

Opis:
In an emergency situation, imitation of strategies of neighbours can lead to an order-disorder phase transition, where spatial clusters of pedestrians adopt the same strategy. We assume that there are two strategies, cooperating and competitive, which correspond to a smaller or larger desired velocity. The results of our simulations within the Social Force Model indicate that the ordered phase can be detected as an increase of spatial order of positions of the pedestrians in the crowd.

Opis:
The 19c. physics is a cognitive archetype of contemporary economics, where static, linear, closed systems that head for thermodynamic equilibrium were of great importance. In this standard of scientific knowledge were included selfish aspirations of agents, which served to prove stability of market equilibrium. The strive of entrepreneurs after profit maximization brings economic systems to a stable Cournot-Nash state of equilibrium, which is determined by the point of crossing of reaction curves. This type of reasoning still sets standards for education of microeconomics. Meanwhile, numerical explorations of simple, standard, nonlinear models of oligopoly prove that Cournot-Nash points are stable only over shortest periods. These are periods in which variables are changing (production values), and parameters (marginal costs) remain constant. According to a convention adopted in economics, in short periods various kinds of costs can change, including marginal costs. The only unchanging category in these periods are fixed costs. The postulate of profit maximization induces entrepreneurs to lower marginal costs. It provokes drifting of markets along short-term equilibrium states towards states of higher complexity. States far from equilibrium are natural market states. It contradicts the basics of traditional microeconomics. Selfish aspirations of agents do not guarantee stability of market equilibrium.

Opis:
Cooperation is essential to biological organizations and human society. In this paper, the conditions of dilemmas resolving by quantum strategies in the three games, Prisoners' Dilemma, Chicken Game and Stag Hunt, are presented. The rule for the evolution of cooperation in general quantum games, b/c > $coth^{2}γ$, is put forward. The formation of the rule is similar to those of the five rules in the classical game theory summarized by Nowak. b/c is still the benefit-to-cost ratio of the altruistic act, while γ is a measure for the game's entanglement. The rule is the prerequisite for the realization of cooperation in quantum games.
