  • The family in forming values of trust among the youth of the modern Russian city

    Family is the most important actor in cultivating values of trust in the youth environment, however, the effectiveness of implementing this feature of the Russian family is limited to the trends occurring on the macro level and marked by a lack of trust in society, both at the macro and micro levels. Very clearly a crisis of confidence manifests itself in the urban environment of Russian society. Eventually, trust transforms into a family value that identifies the microcosm of the family interactions. The reality of the external world to the world of the family, urban youth perceive as socially unjust and full of distrust, determines, in the end, and the low trust rating in the system of values of young Russians.

  • Security: destabilization and modelling processes of peace-making of society in gender research field

    This article is devoted to the problems of destabilization, conflict and problem areas in contemporary gender and family relations, mostly in the system of social roles realization. Selected problem areas promote not only destructive forms of relationships within the family unit and cause individual deep sense of dissatisfaction with life, but destabilize society on the whole, destroying peace and tranquillity both locally and globally. It is known that some contemporary types of gender and marital-family problems are very destructive to the existence of the whole social system. Such, in particular, can be called the imbalance of roles and inadequacy of prestige of the spouse/partner. Due to the urgency of the identified problems there increases the need for modeling the processes of peacemaking in the society, where the main actors can certainly become women. Female gender sub-group played a prominent role in peacemaking, in particular, during WW II , performing a variety of social roles.

  • Calculation of the effect size when using nonparametric tests for comparing samples in psychological research using the R software

    The limitations of statistical significance in psychological research become more and more obvious. On the contrary the effect size reporting in scientific papers is now a common practice as it shows the practical significance of the research. Various methods of computing the effect size exist, but many of them are not represented in popular statistical software. The using of the R statistical software for educational and scientific purposes is suggested, as it is free and open-source, and user functions for different purposes can easily be written. Four R functions for computing the effect size for rank comparison tests of samples are proposed.

    In this article we consider technique of determination of degree of homogeneity of heterogeneous mixtures by using tool contactless method. This method uses optoleptical information of mixture surface. This method can be used in automatic control systems. An optoleptical information may be obtained using standard devices of photosensitive scanning. The value of entropy of otptoleptical information is used to estimate the degree of mixture homogenization. Operations of component mixing are widely used in technological processes. The degree of homogenization of mixture is the one of quality indicators of mixing process. The degree of homogenization is usually determined by laboratory method, which requires additional time for analysis. The degree of homogenization can also be determined by using the senses. In this case, the results of determination depends on the experience of the expert. In this article we looked at an example for the paint industry.

  • "Mathematical modeling and computer graphics of kinematical ruled surfaces on the base of interior revolving one axoid by another in the pairs of contacted cylinders and cones "

    On the base of geometrical model of interior revolving one axoid by another for the pairs of contacted cylinders and cones analytical representations, and computer visualization of the new constructed kinematical surfaces is developed in this research. The described geometrical model corresponds to the case when one axoid is located in the interior of another axoid. As this takes place, there are two possible variants of mutual arrangement of moving and fixed axoids. In the first variant, the moving axoid is located in the interior of the fixed axoid. In the second variant, the fixed axoid is located in the interior of the moving axoid. In the first variant, the outside surface of the moving axoid revolves around the interior surface of the fixed axoid. In the second variant, the interior surface of the moving axoid revolves around the outside surface of the fixed axoid. For pairs of axoids “cylinder – cylinder” or “cone – cone” both variants of geometrical model for constructing kinematical ruled surfaces are considered on the base of rolling one axoid along another one. As a result of the moving one axoid along another the kinematical ruled surface is generated by one of the generating lines of moving axoid. Computer graphics of the new constructed kinematical ruled surfaces based on the proposed geometrical models has been accomplished by the previously developed software application “ArtMathGraph”.
