In this paper, the stability of a cubic functional equation in the setting of intuitionistic random normed spaces is proved. We first introduce the notation of intuitionistic random normed spaces. Then, by virtue of this notation, we study the stability of a cubic functional equation in the setting of these spaces under arbitrary triangle norms. Furthermore, we present the interdisciplinary relation among the theory of random spaces, the theory of intuitionistic spaces, and the theory of functional equations.

The paper presents theoretical reflection upon international marketing strategy in the framework of internationalization and globalization of the market. It consists of four parts. The first one debates the nature and reasons for corporate internationalization. The second part shows an international marketing strategy in the concept of corporate expansion. The strategy consists of two elements： the basic dimensions of foreign market entry modes （part 3） and business presence strategies in overseas markets （part 4）. This paper proposes a theoretical framework for research conducted by Department of Marketing of the cracow university of Economics. The research has been conducted as a part of grant received by Polish National Centre of Science.

An important feature of local self-government which differs from other public authorities should be the independence of its organs from the government system of administration. The empowerment of local communities, which takes place in all democratic states, has been achieved by giving the guarantee of autonomy to local self-government, including financial autonomy. These are fundamental assumptions of local self-government functioning. The subject of this paper is to present self-government, in the field of shaping the basic sources of public tasks. issues relating to the financial autonomy of loca of its financial supply in cash, enabling the performance
