Drawing tests, as a model of hierarchical interrelations and inversions in the psychic structure, are an important object of philosophical research. By means of this model, we can learn a lot about hierarchical systems. The author relied on the presence of a hierarchical system in human activity stated by the great ...

• Distribution of NQR relaxation times in the rotating frame of reference in micro-sized crystallites

  ... study into the effect of powder crystallite size on spin-lattice relaxation times in a rotating frame for 35Cl NQR in potassium chlorate, as well as the nutation interferograms. To obtain the distribution of relaxation times, a multi-exponential decay inversion of the longitudinal component of the nuclear magnetization in a rotating frame was used. The multimodal nature of distributions is explained by the influence of surface irregularities and impurities. 1. Slichter C. P. Principles of Magnetic ...

At the same time, the specific features of the region’s geoeconomic position magnify the ‘inherited’ ad acquired effects of focal industrialization and space polarization, which creates additional prerequisites for the inversion of the Russian economic space — ‘Russia of the physical space’ and ‘the economic space of Russia’. The study uses traditional methodology of economic geography (the territorial, cluster, and spatial approaches) and the geoeconomic ...

• The antinomy of political reason. Some deliberations on Kant’s “Answer-ing the Question: What is Enlightenment?”

  ... when the interests of government and citizen coincides. Russian history is addressed to illustrate that even “common interests” of the ruler and the citizen leave room for a conflict between them. The author analyses Kant’s paradox stating an inversely proportional connection between the level of civil liberties and that of spiritual freedom. The article proposes a hypothesis about the dissident movement as a possible political form of implementingthis paradox. This dilemma helps to formulate ...

• The coastalisation of population in today’s Russia: A sociogeographical explication

  ... to demonstrate that, during the post-Soviet period, coastalisation has become city-centred and regionally/locally selective with a focus on the agglomerations of the Baltic, Caspian, and partly Azov- Black Sea coasts. The multi-scale phenomena of ‘inverse coastalisation’ and ‘quasicoastalisation’ are analysed and relevant cases are considered. The author identifies numerous factors and explores prospects of the further coastalisation of population in the Kaliningrad and Leningrad regions ...
