Regional population expenditure for foodstuffs in the Russian Federation: componential and cluster analyses

The article describes the solving of the problem of conducting the component and cluster analyses of population expenditure on food as one of the most important components of the standard of living. The purpose of the analysis is to develop the regional clusters of the Russian Federation, which vary in the structure of household expenditure for foodstuffs. The foodstuffs are presented in absolute units taking into integral account the standard of living index. The methods of intellectual analysis such as component and cluster analyses are applied as the research methods. The procedure for the data intellectual analysis based on the interconnected performance of component and cluster analyses is proposed. The procedure of the data intellectual analysis considers the interrelation between the results received by different methods, and also the possibility to return to the previous method for the purpose of repeating the analysis to specify consistently the clusters composition. Few clusters of the wealthy regions characterized by the high and average levels of expenditure for foodstuffs are revealed as well as the quite many clusters of not enough wealthy and not wealthy regions characterized by the low level of expenditure for foodstuffs. It is shown that the growth of standard of living characterized by the size of a gross regional product per capita is followed by the growth of the Gini coefficient, which indicates both the inequality of income distribution and reduction in expenditure for low-value foodstuffs. The results of the analysis can be applied to the development of the decision-making support system intended for the analysis of the scenarios of macroeconomic regulation in the eld of income policy for the purpose of increasing the standard of living of population. The analysis of the population expenditure for foodstuffs has allowed to reveal the cluster structure of the regions of the Russian Federation, to show it according to the generalized indications, to formulate the specific characteristics of the clusters of the regions and important management decisions

The significance of late anthropological collections

Late medieval anthropological materials are rarely subjected to scientific research. The authors of this work attempt to demonsrate the importance of such investigations. Despite a rather large number of writen sources, late anthropological materials can significantly extend the collection of sources related to the specified period. In order to illustrate this concept the authors conducted an analysis of paleoanthropological materials from the island town of Sviyazhsk dating back to 16th-17th centuries. The materials have been discovered at excavations of parish Orthodox burial grounds. All the burial grounds date back to the same period, which allowed the reearchers to incorporate the materials into a single series. The investigation was conducted in accordance with a standard program adopted in the Russian Federation: determination of gender and age; subdivision of the collection into two series on the basis of gender; intragroup and intergroup aalysis of the series. This article features a analysis of the male portion of the collection, as investigations of male collections is more widely used in palaeoanthropology, and much more reference material is available for their execution. The analyzed material was subdivided into the following two series: the first one comprised materials from a monastery burial ground, and the second – parish necropoleis of the town. An intergroup comparison was conducted with the application of canonical analysis. A dendrogram was plotted in order to visualize the acquired data. As a result of conducted invesigation the authors established that both monastery and parish series from the island town of Sviyazsk subjected to intragroup analysis demonstrate their correspondence to the Eu Caucasian group with a Mongoloid component of local Ural origin in the morphology of sculls from the parish series. An intergroup aalysis revealed a morphological similarity of the parish series with the Russian series from Moscow governorate illustrating the local colonization routes. Thus, as a result of investigation the authors acquired new information on the history of the Middle Volga region providing an insight into the origination of the anthropological appearance of local peoples.peer-reviewe

Zonal Velocity Bands and the Solar Activity Cycle

We compare the zonal flow pattern in subsurface layers of the Sun with the distribution of surface magnetic features like sunspots and polar faculae. We demonstrate that in the activity belt, the butterfly pattern of sunspots coincides with the fast stream of zonal flows, although part of the sunspot distribution does spill over to the slow stream. At high latitudes, the polar faculae and zonal flow bands have similar distributions in the spatial and temporal domains.Comment: To appear in Solar Physic

Methodological Approach to Measure the Quality of Life of the Region’s Population

The article is devoted to the urgent problem of the regional development, i.e. to the development of methodological tools to evaluate the quality of life of the population in the region. The article considers the concept of “quality of life”, and the terms related thereto; and substantiate the author’s position with respect to the concept. The existing domestic and foreign approaches to evaluate the quality of life of the population were analyzed, and the application of the comprehensive approach was reasoned within this study. The criteria for evaluation of the quality of life of the population were distinguished. The authors proposed the methodological approach that considers not only objective indicators of the quality of life presented in the statistical reports of the Russian Federal State Statistics Service, but also employs subjective evaluations of the local population enabling more appropriate evaluation of the quality of life in the region. The methodological tools of the research include mathematical methods of statistical data processing and online survey of the population about the level of satisfaction with various aspects of their life. The methodological tools were tested using the example of the Sverdlovsk Region that is characterized both by the steady improvement of statistical indicators of the quality of life and by low satisfaction of population with certain aspects of the quality of life, which generally decreases the integrated indicator of the quality of life despite positive dynamics of social and economic development of the region and vigorous social policy of the regional authorities. The proposed methodology was used in the evaluation of the quality of life of the Sverdlovsk Region population as part of the development of the Concept of comprehensive regional program “New quality of life of Ural residents” (Decree of the Governor of the Sverdlovsk Region No. 45-UG dated January 29, 2014 “On the Concept of the life quality improvement for the Sverdlovsk Region population before 2030 year — “New quality of life of Ural residents”).The article has been prepared with the support of the grant of the Russian Foundation for Basic Research (RFBR) No. 15-06-09169 “Development of methodical measurement tools and evaluation of the impact of social, economic, medical and demographic factors on mortality rates of working-age population”

The 35S U5 snRNP is generated from the activated spliceosome during In vitro splicing

Primary gene transcripts of eukaryotes contain introns, which are removed during processing by splicing machinery. Biochemical studies In vitro have identified a specific pathway in which introns are recognised and spliced out. This occurs by progressive formation of spliceosomal complexes designated as E, A, B, and C. The composition and structure of these spliceosomal conformations have been characterised in many detail. In contrast, transitions between the complexes and the intermediates of these reactions are currently less clear. We have previously isolated a novel 35S U5 snRNP from HeLa nuclear extracts. The protein composition of this particle differed from the canonical 20S U5 snRNPs but was remarkably similar to the activated B* spliceosomes. Based on this observation we have proposed a hypothesis that 35S U5 snRNPs represent a dissociation product of the spliceosome after both transesterification reactions are completed. Here we provide experimental evidence that 35S U5 snRNPs are generated from the activated B* spliceosomes during In vitro splicing

The professional transspective of the students in the conflicting realities of the post-industrial society

The topicality of the issue under investigation is determined by the rising demand of the Russian society in the mastering and controlling conflicting realities that are capable of changing the integral notional structure of an individual, leading to the evolution or degradation of such individual’s social and professional life activity. The purpose of the article is to identify the professional positions and views of the modern students in conditions of affecting their internalities, motives, and values of the conflicting realities, defining methods of negotiation of the latter. The leading methods of the research of this problem are the art technology that consists of the representation of the personal professional path in future, the postpictural interview, the questionnaire method, qualitative data analysis, allowing to identify the features of the professional transspective of the students in the conflicting realities. The following results have been achieved: the analysis of the professional transspective of the students, whose self-realization occurs in the post-industrial society, was provided, the reasons (conflicting realities) of the obtained data were found, the methods to overcome the impact of the conflicting realities on the personality were proposed. The research materials may be useful for the psychologists of the professional education, the teachers of the vocational training in the organization of accompaniment and rendering assistance in the professional self-realization of young people in realities of the post-industrial society. © 2016 Zinnatova, Konovalova and Makarova
