REVIVAL OF PRESTIGE OF MANY CHILDREN FAMILY BY MEANS OF A STATE SUPPORT

abstract 1221608053 issue 122 pp. 757 – 772 31.10.2016 ru 783
In this article, a family is considered as a basis of modern society. As a result of the theoretical and methodological analysis, there was determined that a family is a form of a social system of a state making impact on the personality from birth to death, by means of formation and change of social, psychological, cultural, ethical bases, differing by means of united economic space, moral communications, interrelationships. Owing to social and economic, political, psychological changes of the country, the life of the population and the model of a family were changed, so the economy of family business turned into individual economy of societies that led to the development of a consumer relation of a society, economic recession, deterioration of ecological situation of environment. Proceeding from selective inspection of budgets of households, there was revealed that the more children in a family, the worse it’s standard of living, so in full families at the appearance of one child the standard of living decreases by 16%, the second child – for 30%, the third – for 50%. According to Rosstat, there was defined that the living conditions also depend on a number of children in a family. On average, better living conditions are at the citizens living lonely with 34 sq. m of living space, the share on a family from three people – 11 sq.m of living space on the person. Different forms of support are given for improvement of life quality of large families by the state. In the article, there was considered one of the key forms of the state support – improvement of living conditions of families having three and more children, namely granting of free of charge land plots in property and providing them with necessary infrastructure. There was offered the alternative mechanism of the solution of housing problems of large families which realization will allow to reduce a social inequality of different segments of the population, will provide the rejuvenation of the nation, both in demographic, and in socio-cultural value

THE ROLE OF LAND, WATER AND MINERAL RESOURCES IN THE CONFLICTS IN AFRICA AND THE WAY FORWARD

abstract 1221608020 issue 122 pp. 278 – 291 31.10.2016 ru 1010
The scarcity of natural resources has become a serious problem in terms of security in the world. This article examines the role of the limited resources in conflicts in Africa. The main source of conflict is the issue of control of resources and the right to a healthy environment. Here we consider the case of the regional conflicts in the African context. A large number of major rivers in Africa also have been the cause of conflicts between the riparian countries. However, most of these problems have been successfully solved, and in many cases, this process led to the formation of regional blocs for economic and diplomatic cooperation in the region. In addition to inter-State disputes, there are also internal disputes among regions or states within the same country for the control of resources. However, in some cases these regions have developed wellcoordinated approaches to resolving the disputes: either by judicial apportionment, congressional action or based on negotiated compacts. In general, we believe that a careful application of equitable resource-sharing formula to volatile areas is a basic condition for peace and stability in Africa

THE SHORTAGE OF WINTER WHEAT GRAIN CAUSED by P. triticina

abstract 1221608085 issue 122 pp. 1284 – 1293 31.10.2016 ru 484
The article studies the influence of the interaction of two technologies of plant protection: breeding- immunological and chemical. The studies were conducted on the varieties and lines of soft winter, durum wheat and triticale, established in Krasnodar research institute named after P. P. Lukyanenko, and also, on varieties of an alien and foreign selection. When considering the correlations in the group of genotypes, forming a necrotic type of reaction to the introduction of the pathogen (the first group of varieties), the significant negative correlation (r - 0,76) between the change in the mass of 1000 grains and the number of unproductive stems formed by one plan was established. The model of the severity of brown rust pathogen in sparse crops of wheat has been collaborated. According to the model, the development of the pathogen in the tissues of the leaves of the host plant leads initially to a change in the relations of the productive and unproductive stems. The change of these parameters significantly affects on the variability of indicators such as the mass of grains from one ear, number of grains per ear and 1000 grain weight. Negligible volatility of weight for 1000 grains suggests that the major losses of productivity in the flowering stage are due to abortive flowers. This model can explain the increase in the mass of 1000 grains in some varieties for tolerance change experiments with the defeat of plants of P. Triticina on micro-plots

QUANTIFICATION OF THE DEGREE OF MANIPULATION OF THE H-INDEX AND ITS MODIFICATION RESISTANT TO MANIPULATION

abstract 1211607005 issue 121 pp. 202 – 234 30.09.2016 ru 1010
In the USSR higher attestation Commission from 1975 to the collapse of the USSR was subordinated not to the Ministry of education and science, but to the Council of Ministers of the USSR directly. However, since then there is a steady trend of gradual reduction of the status of the Commission. Today it is not just included in the Ministry of education, it is just one of the units of one of its structures: the Rosobrnadzor. Reduced status of the HAC inevitably leads to a decline in the status and in the adequacy of scientific degrees assigned as well as scientific ranks. This process of devaluation of traditional academic degrees and titles assigned to the HAC, has reached the point when a few years ago there were abolished salary increments for them. Now, instead of that, every university and research institutes have developed their local, i.e. non-comparable with each other scientometric methods of evaluation of the results of scientific and teaching activities. Despite the diversity of these techniques, there is a common thing among all of them, which is the disproportionate role of the h-index. The value of the Hirsch index starts to play an important role in the protection, when considering competitive cases for positions, as well as in determining the monthly rewards for the results of scientific and teaching activities. By itself, this index is well founded, theoretically. However, in connection with the practice of its application in our conditions, in the collective consciousness of the scientific community there was a kind of mania, which the authors call the "Hirschmania". This mania is characterized by elevated unhealthy interest to the value of the Hirsch index, as well as incorrect manipulation of its value, i.e. inadequate artificial exaggeration of this value, as well as a number of negative consequences of that interest. In this study we have made an attempt to construct a quantitative measure for assessing the extent of improper manipulation of the value of the Hirsch index, and offered a science-based modification of the h-index, insensitive (resistant) to the manipulation. The article presents a technique for all the numerical calculations, which is simple enough for any author to use

RUSSIAN SCIENTIFIC SCHOOL IN THE ECONOMETRICS FIELD

abstract 1211607006 issue 121 pp. 235 – 261 30.09.2016 ru 622
We have considered the formation of the Russian scientific school in the field of econometrics, obtained its obtained scientific results, the possibilities of their use in solving problems of the economy, the organization of production and controlling of industrial companies and organizations, as well as in teaching. As econometrics we consider a scientific and an academic discipline devoted to the development and application of statistical methods to study economic phenomena and processes, in short, statistical methods in economics. Therefore, we can say that a lot of domestic books and articles, in particular, the works by the author of this publication from the beginning of the 70s, are the parts of econometrics. However, in this article we consider only the works, in the titles of which we can see the word of "econometrics". In our country the term "econometrics" has become popular since the mid 90s. However, many publications and training courses are still developed in the western outdated paradigm. They do not conform to the new paradigm of mathematical methods of economics, the new paradigm of applied statistics and mathematical statistics, mathematical methods of research. Russian science school in the field of econometrics operates within the scientific school in the field of probability theory and mathematical statistics based by A.N. Kolmogorov. Russian science school is developed in accordance with the new paradigm of mathematical methods. It is necessary to examine the main results of Russian scientific schools in the field of econometrics. We present the information on the institutional design of national scientific schools in econometrics, in particular, on the activities of the Institute of High Technologies statistics and econometrics

CLARIFICATION OF A MODEL OF A BALANCING ROBOT BY LOGICAL AND EMPIRICAL METHODS

abstract 1211607011 issue 121 pp. 336 – 356 30.09.2016 ru 664
This work studies the mathematical model of the object “inverted pendulum” on the example of the unstable electromechanical devices which is balancing robot on wheel couple. Unfortunately, many details of object model are unknown. Logical and empirical method offers hypotheses about the difference between the actual object model from its mathematical approximation based on logical analysis with subsequent refinement of this model and testing of the hypothesis with modeling of the systems with the updated model. As a result, the amendments to the model have been found containing nonlinear components. With the help of these amendments, the dynamic characteristics of the actuator, filters, friction and the tendency of the object to fluctuations are better taken into account

TO THE RESEARCH METHODS OF FAULTS UNDER THE VIBRATION IMPACTS

abstract 1211607033 issue 121 pp. 647 – 659 30.09.2016 ru 444
We propose an approach to the modeling of stressstrain state of lithospheric structures near faults by modeling them as Kirchhoff plates on threedimensional elastic foundation. We describe an efficient method of solving problems for plates with rectilinear fractures, based on the transformation of the differential operator, which allows us to analyze the solutions obtained for different contact conditions in the area of the fracture. The method is presented on the example of the vibration problem of two elongated plates on the surface of the elastic layer under the effect of concentrated surface load. The results of numerical implementation of the developed algorithm make it possible to identify the influence of the substrate properties, characteristics of the plates and the nature of their border interactions on the picture of wave process in the test structure. At the same time obtained configurations of the harmonic signal passage through the fracture can serve as an indicator of its type. The proposed approach should be used to determine the presence and type of fractures based on measurements of signals from vibration sources in cases when geophysical environment can be modeled by the previously described structure. The problems of studying objects we reviewed in this paper also occur in various areas of technology, and, therefore we can apply the proposed method for their solution

SIMULATION MODELING OF DISTRIBUTION OF EPIDEMICS ON THE BASIS OF AGENT APPROACH

abstract 1211607085 issue 121 pp. 1369 – 1379 30.09.2016 ru 778
Today, infectious diseases remain a leading cause of premature deaths in the world. Agent-based modeling can play an important role in predicting the spread of disease and to assess the containment measures. The aim is to construct a multi-agent simulation model for the formation of epidemic measures to reduce effectively their incidence. Using the multi-agent simulation approach to modeling of epidemics due to the fact that the approach allows us to consider a number of factors influencing the epidemic process, makes it possible to carry out numerical experiments. The processes of the spatial distribution and temporal variation of these two groups of epidemics of infectious the author calls dynamics. Usually hard-implemented spatial components of the dynamics in the proposed model can be substituted by predfractal topology of the graph, which is built up by voluminous graphs - primers, and the dynamics of compounding prefractal graph, called its recognition, is responsible for the timing of the process component. Under the term of agent, we consider an elementary study participant. An agent is active; it is in a state that may change under the influence of factors. The properties of the agent are attributed characteristics that form the level of immunity: height, weight, gender, income, marital status, education, geography

PARTICLE COLLISIONS IN THE RICCI FLOW

abstract 1211607111 issue 121 pp. 1787 – 1808 30.09.2016 ru 527
In this work, we investigate the problem of collisions of particles linked to the singularities of the gravitational field in the Ricci flow. A system of non-linear parabolic equations describing the evolution of the axially symmetric metrics proposed. We consider the metric having axial symmetry and comprising two singularities simulating particles of finite mass. There was numerically investigated the change of the metric in the collision of particles. Two formulations of the problem have been considered, one of which scatter particles after the collision, and the other as a result of the merger of two particles, a new stable static system, which can be interpreted as a new particle. The initial and boundary conditions using the exact solution of the static problem, so the collision persist particularly metrics caused by the presence of particles. In numerical experiments determined that the collision of the particles in the Ricci flow leads to the formation of gravitational waves, similar in structure to the waves, registered in the LIGO experiment. Consequently, we can assume that the observed gravity waves caused mainly by transients associated with the change in the metric system. A model describing the emission of gravitational waves in the collision of particles in the Ricci flow proposed. The influence of the parameters of the problem - the speed and mass of the particles, on the amplitude and intensity of the emission of gravitational waves was numerically simulated
