The Welfare and Public Health of the Population of Russia: Adaptation To Economic Volatility
In the article, the results of the research of correlation of welfare and public health of the population of Russia in the conditions of economic instability are presented. The review of performance indicators of development of public sentiments of society applied both in Russian and foreign practice is submitted. The concept content of the “social and psychological potential of a region” as an indicator of public health of the population is opened. On the basis of this concept, the potential pattern is created. The evaluation method of social and psychological potential of a region is developed, its main idea is an integrated assessment of both the potential of a region in general and its separate components. The assessment of the condition of potential in territorial subjects of the Russian Federation is given. Character and power of correlation between indicators of welfare and level of social and psychological potential of territorial subjects of the Russian Federation on the basis of development of correlation matrixes are revealed, also, the regional consistent patterns and tendencies are determined.The study was funded by a grant from the Russian Science Foundation (project No. 14-18-00574, “Anti-crisis”, an Information Analysis System “: Diagnostics of the Regions, Estimation of Threats and Scenario Forecasting in Order to Maintain and Reinforce Economic Security and Enhance the Well-Being of Russia)
Comparison of the Efficiency of Budget Financing and the Social Security of a Region
The article deals with theoretical and economic aspects of the “security” category and draws a distinction between philosophical, sociological, and economic approaches to the concept of social security. From the perspective of a system approach, the authors define the place of the region’s social security in ensuring national security. The article describes the theoretical content of the «social security» category and provides the authors’ specification for such terms as «social risks,» «danger,» and «threat.» The authors offer methodological tools to evaluate the region’s social security based on a complex assessment of the region’s socioeconomic and budget-financing indicators to identify the risks (deviations) and factors of inefficient financing. The proposed methodological approach is based on identifying the dependencies between the social and financial security of the region. The following indicators reflecting the social security level in the territory of residence were selected as estimated indicators: the region’s consolidated budget income and expenses, gross domestic product growth rates, natural population growth ratio, unemployment level, the share of the population with income below the subsistence minimum. This approach was tested by the example of the Perm Territory and Sverdlovsk Region revealing the regularities as well as favorable and unfavorable periods for the region’s social security. The obtained estimated indicators are ranked depending on the growth (fall) time lag, resilience, and sensitivity to budget financing. The assessment results show that the Perm Territory has been entering a deep recession in terms of national security since 2012. Similar tendencies are demonstrated by the Sverdlovsk Region; however, in view of the apparent diversity and dominant influence of the Perm Territory and the Sverdlovsk Region on the socioeconomic development of the Privolzhsky and Ural Federal Districts, respectively, the provided comparison is of scientific and practical interest.The research has been supported by the Grant of the Russian Science Foundation (the Project № 14–18–00574 "Anticrisis Information Analysis System: Diagnostics of Regions, Threat Assessment, and Scenario Forecasting to Maintain and Strengthen the Economic Security and Welfare of Russia")
Economic tomography: the possibility to anticipate and respond to socio-economic crises
The article discusses an approach based on an original hypothesis related to the peculiarities of Russia’s development (on the one hand, its scale, the Russian mentality and a certain closeness of the economy; on the other hand, a significant dominant resource and human potential, and, as a consequence, a genuine role in the global economic community), the diagnosis of which (at the level of the well-being of individuals and inhabited areas) can be used to identify crises, provide an early assessment of threats to socio-economic development of regions as well as help to evaluate the state of the region over a 3 to 5 year period. In other words, in order to ensure that executives have enough time to mount a sufficiently rapid response to the crises and administrative errors and to reduce the impact of emerging threats. The aim of this paper is to present theoretical and methodological tools for the recognition of the early stages of emerging threats, allowing fewer losses to be experienced during the crisis period. Simulation experiments were carried out for the purpose of classifying previously occurring social and economic crises (9 possible variants were reviewed) and mathematically processed trajectories of change in the main indicators for the well-being of individuals and inhabited areas, taking the influence of various factors into account. On the basis of the authors’ proposed approach (referred to as economic tomography) an attempt is made to comprehensively assess the state of sample representative regions of Russia.The research has been supported by the Russian Science Foundation (project № 14–18–00574 'Information-analytical system "Anticrisis:" diagnostics of the regions, threat assessment and scenario forecasting for the preservation and strengthening of economic security and well-being of Russia')
Compact Precomputed Voxelized Shadows Construction on GPU
We consider the problem of producing high-quality shadows in real-time for 3D computer graphics software. In [1, 4] authors have proposed new data structure for object geometry representation by binary voxel grid. This binary data was packed to directed acyclic graph — traditional sparse voxel octree with merged identical subtrees. This approach has been extended to shadowing by voxelizing shadow volumes instead of object geometry [2, 3]. Obtained structure enables high-quality filtered shadows to be reconstructed for any point in the scene in real-time. In [1–4] authors have used CPU-based bottom-up algorithm that reduces sparse voxel octree to minimal directed acyclic graph. In the present paper we construct new parallel algorithm for such reduction that runs entirely on GPU
Pattern Transitions in Unstable Viscous Convective Medium
Convection in a thin layer of liquid (gas) with temperature dependent
viscosity between poorly heat conducting boundaries is studied within framework
of the Proctor-Sivashinsky model. This model is examined in order to study both
the flow pattern formation and the second-order structural phase transitions as
between patterns with translational invariance as well as between structures
with broken translational invariance but keeping a long-range order. The
spatial spectrum of arising patterns and estimation of their visual
defectiveness are analyzed. The relation between the density of pattern defects
and spectral characteristics of the pattern is found. We also discuss the noise
effects on the formation of pattern defects. The influence of temperature
dependence of viscosity on the process of pattern formation and structure
transformations is also discussed. It is shown that the temperature dependence
of viscosity inhibits structural transition from regular rolls to square cells
