A brief theoretical derivation is presented for the effective conductivity and dielectric constant of a homogeneous medium loaded with a uniform distribution of spherical conducting particles. To account for the effect of induced polarization, the particles are taken to have a concentric membrane or film which has a blocking action to the current flow into the particle. The characteristics of this phenomenological model are very similar to the experimentally observed features of induced polarization in a block of compacted andesite particles which contains a dissemination of small metal particles and is partially saturated with a weak electrolyte.The theory is then extended to a two-layer medium where the lower region is polarizable. The results explain, at least in a qualitative way, the observed features of induced electrical polarization in rocks, soils, and clay.

Development Analysis

The presented study examines methods for analyzing and managing sustainable economic development of Russian regions and possible criteria for assessing and improving sustainability.Aim. The study aims to provide a theoretical and empirical justification for the use of regional competitive attractiveness assessment to manage economic development and improve its sustainability.Tasks. Based on the measurement and analysis of economic competitive attractiveness indicators and their mathematical treatment, the authors assess the sustainability of development of Russian regions in 2013–2017 and the causes of deviations from progressive growth.Methods. This study proposes a mathematical tool for measuring the sustainability of Russian regions by assessing their competitive attractiveness and develops a typology of sustainability in the mathematical space of two variables.Results. Methods for analyzing and managing the sustainability of economic development of Russian regions under the influence of political and economic challenges and risks are proposed. The level and dynamics of regional competitive attractiveness are taken as a criterion of sustainability of economic development. The authors provide methods and indicators for assessing economic competitive attractiveness and criteria for measuring the sustainability of development, which allow them to draw conclusions about the reaction of different regions to the challenges and risks of development in 2013–2017. The study proposes a management scheme for sustainable regional development with a focus on the comprehensive improvement of regional economic competitive attractiveness and potential ways to improve it, including training of municipal and regional managers in crisis management associated with economic and political challenges and risks.Conclusions. Based on the proposed criterion of economic development sustainability and assessment of the competitive attractiveness of regions and their rankings, it is shown that in 2013–2017 45 out of 83 regions were developing sustainably; by 2017, 19 regions out of the 32 that suffered losses in the competitive attractiveness level and rankings in 2015–2016 have managed to restore the sustainability of economic development and their rankings. This study proves that regions with a high level of economic competitive attractiveness show increased sustainability of development.

Dialectic Of Enlightenment

The article analyzes methodological errors Theodore Adorno and Max Horkheimer’s Dialectic of Enlightenment, particularly their incorrect use of the concepts of mimicry and mimesis. The author of the article maintains that the leaders of the Frankfurt School made a mistake that threatens to undermine their argument when they juxtaposed mimesis and the attraction to death, which has led philosophers to trace back to mimesis the desire for destruction that is found in a civilization constructed by instrumental reasoning. The author reviews the arguments of the Dialectic of Enlightenment and emphasizes the unsuccessful attempt to fuse Freudian and Hegelian methods, which exposes the instability of opposing scientific reasoning to “living” nature. Some amusing quotations from Roger Caillois, who refused to think of mimesis as something entirely rational, are also brought to bear. As Brassier gradually unfolds Adorno and Horkheimer’s thesis, he indicates the consequences of their mistake, which confined thinkers to the bucolic dungeon of “remembering” the authentic nature that they cannot abandon because they have denied themselves access to both reductionist psychological models and to phenomenological theory as such. Brassier delineates the boundaries of this trap and notes the excessive attachment of the Dialectic of Enlightenment to the human. Brassier goes on to describe the prospects for a civilization of enlightenment: a mimesis of death in both senses (death imitates and is imitated) finds its highest expression in the technological automation of the intellect, which for Adorno and Horkheimer means the final implementation of the self-destructive mind. However, for Brassier it means the rewriting of the history of reason in space. This topological rewriting of history, carried out through an enlightenment, reestablishes the dynamics of horror more than mythical temporality: it will become clear that the human mind appears as the dream of a mimetic insect.
