Monotowns: A New Take on the Old Problem
... They identify key reasons behind monotown vulnerability and systematize stakeholders’ risks. The authors then posit that a study of monotown- related issues would be incomplete without accounting for stakeholders’ interests and relations. Monotown problems become apparent in the context of institutional agreements carried out with high transition costs and increased risks of opportunistic behaviour encountered by the institutional agreement stakeholders. Solving these problems through the methods ...
The research of the collective activity to overcome a diagnostic problem
... from the position of a council of physicians of the same (rarely) or different specialization is growing. Convening a council is often difficult or it is necessary to wait for a long time. Therefore, modeling mechanisms for solving of a diagnostic problems and its and cognitive visualization is relevant. The latter is also due to the fact that the safety of the made decisions depends on the speed of the doctor's response to the emerging problematic diagnostic situation. The paper is dedicated ...
Analytic Work on Kant — Idealism, Things in Themselves, and the Object of Knowledge

Within this interpretation, this paper considers the problem of differences between the ontological aspects of Immanuel Kant’s critical philosophy and Edmund Husserl’s phenomenology, since most interpreters consider these two thinkers the most prominent exponents of transcendental philosophy. The differences ...

The introduction of the concept of appearance allows Kant to solve the semantic problem of the conformity of the representation to the object. In this case, appearance is not an object, but just a designation of the object (KrV, B 235). Thus, appearance cannot be understood ontologically as a physical object or a relation. At the ...

The authors emphasise the importance of public-private partnership (PPP) in minimising such risks in order to enhance the region’s attractiveness and to solve development problems. PPP has never been studied as a means to minimise regional investment risks in current conditions. This accounts for the scientific novelty of examining investment risks minimisation through proving the essentiality of developing PPP mechanisms ...
The problem of meaning in Social Semiotics: Max Weber today

Based on the Weber’s definitions and their possible modification, we suggest the transdisciplinary synthesis around the study of the problem of meanings and their manifestation. Meaning production is understood as a result of the conjunction of linguistic and extralinguistic systems in the process of social interaction and communication. This allows to convert actional meanings into ...
