  • Happy childhood as the basis for the social health of young generations: sociological indicators of measurement

    Presented by the authors in the article an analysis is made of the safe childhood and the authors, on the basis of the concept of research, offer safe to consider childhood as a social phenomenon that characterizes the process of socialization and maturation of the personality from the standpoint of the creation of all necessary conditions for the formation of its physical and social health. Under the social health of the young generation authors is understood as a state of well-being considered from the perspective of primary family socialization, parent-child relations, the system of socialization of family values and preferences, ethical and moral norms of family society, a reflection of the attitude of parents to their children. The main conclusion by the authors, is that childhood in modern Russia is gradually losing safe features that, in turn, defines a deep interest in the issue of childhood in Russia and the need for timely diagnosis and sociological well-being/ill-being of childhood as an indicator of future social, spiritual and physical condition of Russian youth.

    This article describes electronic design software tools OrCAD implementation for the quadrature MSK-signals (minimum shift keying) modulator creation. Emulation results are presented: digital and analog signals, the output spectrum. The model is designed to generate MSK-signal and study their changes in various RF paths, using all possible analog-digital circuit simulation of OrCAD. The presented model is parametrized. The determinative model parameters are MSK-signal central frequency and pulse duration of modulation sequence. The input sequence - unipolar digital signal is read from an external text file. Realization of a parametric model of the MSK-signal modulator in OrCAD allows the researcher to quickly and easily change the parameters of the signal and to carry out research directly into the package without resorting to third-party software tools, thereby reducing the complexity and development time. The model can also be used in the study subjects issues concerning digital data transmission.

  • A multilevel model of latent conflict potential student RGSU (by mid 2014)

    It is given the interpretation of the primary parameters of conflict obtained by survey (137 people). The studied audience was typical for undergraduate students on basic social characteristics. In the questionnaire the various parties to the cognitive perception of the political order were identified by direct survey. And the emotional relationship to local and Central government were obtained on the technology of semantic differential. The model is based on the results of the parallel hierarchical factorization cognitive components. On the first level 14 of the primary signs reduced to five factors. They characterize the socio-political expectations, declared and real political activity, evaluating the legitimacy of authorities and political situation. These indexes, in turn, on the second level are combined into two independent factors: General cognitive activity and perception of political orders. In the model the indices of the affective perception of these orders (calculated on the basis of the affective section of the questionnaire) were added to them. Two-dimensional histogram of the distribution component matrix for the respondents shows that the subgroup with both highly negative emotional perception and political activity is low (for example, a value of the first parameter -0.4 and below, and the second 0.4 and above is characterized by only 4% of respondents). These respondents represent a risk for the possibility of forming protests.

  • A learning efficiency assessment in case of complex open ended assignments using expert methods

    It is necessary to get a complex integral assessment in object control in different domains. The complex integral assessment is an indicator of problem presence or problem absence in work of control object. It is necessary to get the integral assessment in training control too when there are complex open ended assignments in a training course. In the paper a learning efficiency assessment technique in case of complex open ended assignments is described. It is based on integral indicator assessment using expert methods. The technique was used in the education process in Ufa state aviation technical university during the performance of term papers on the subject «High-level programming». The technique allowed to assess the training course and identified the need for its updating to improve learning efficiency.

This is connected with not comprehensive complex open ended assignment statistics and difficulties during the problem analysis. In the paper a complex open ended assignments-specific technique is suggested. The technique allows an instructor to analyze problems of training course and their sources conveniently and in detail and correct training model using learning results. The technique and a tool based on it were used in the education process in Ufa state aviation technical university during the performance of term papers on the subject “Design of automated system of data processing and control”. The learning efficiency increased by 14% as a result of using the technique.

  • Problems of readiness of contemporary Russian youth for family formation: ideal and real behavior models

    Readiness of contemporary youth for formation of stable marriage-family relations is a necessary factor forming stable functioning of a society and also a determining factor of social and national security, which is very essential nowadays in the conditions of non-stability, various challenges and risks. Compatibility/non-compatibility of ideal behavior models of the contemporary youth with the real models in the chosen aspect represents itself as an important criterion of determination of readiness/not readiness of youth for family formation. Today there have been distinguished the factors influencing the formation of an ideal partner of other gender, these are family (parents, relatives), referent groups, first experience of communication with other gender, mass media, etc.

  • The internal structure of political attitudes by students of Grozny (according 2015)

    The work was performed on the experimental data obtained by questionnaires in mid-2015 among the students of the Grozny state oil technical University. All were interviewed 107 people. This sample was typical for the University on basic social indicators. The questionnaire consisted of two blocks, "of cognitive" and "affective" characters. The parameters of the perception of power, the level of protest, involvement in political processes (a total of 14 signs) were identified by a direct survey In the first part. Parallel hierarchical factor analysis conducted on these grounds. On the first level five independent parameters are identified. They are indices of socio-political expectations, the legitimacy of power, declared and observed political activities and assessment of the political situation. On the second level all of them are reduced to two factors. They define the General political activity and cognitive component perception of political power. The work gives the distribution function, all identified factors that characterize the structure of the cognitive components of political attitudes. On the second level indexes of emotional perception of local and Central political orders received in the affective section of the questionnaire are added to them. All the set of factors of the first and second level fully describes the various aspects of conflict, as reflected in the questionnaire.

  • Arch designs demanded by the time in building sciences and architecture

    The article presents a review of recent projects of arch designs, work on their research. Arch structures are widely used in construction since ancient times. The Romans were the first to use the arch of considerable size, and some of them survived until our days. One of the examples of arch structures in Roman architecture is the Roman aqueduct of Pont du Gard. Accident arched constructions mostly occur due to buckling of the entire structure. Risk of accident from loss of stability is especially great because buckling can occur suddenly. The loss of stability as possible out of plane and in plane. Flat design farm, arches, frame resistance to bending in the plane of the structures than from the plane. Cases of accidents of industrial and civil constructions, which occurred from buckling lateral torsional buckling is little known. Buckling lateral torsional buckling of structures, working in transverse bending, is given little attention, as it is believed that if and has in some cases place, it would not lead to accident due to their shared relationship of beams with other designs.
