  • Declarative and real perception of friendship by DSTU students Part II

    The work consists of two parts and is devoted to a comparative analysis of the declared cognitive and actually perceived affective relations to friendship. In the second part, the distribution functions for the entire hierarchical system of factors identified in the first part and reflecting the structure of the cognitive perception of friendship by DSTU students are presented. It was found that the overall cognitive attitude of the group is positive. For two indicators of the second level and the integral factor of all cognitive perception, about 80% of all respondents are characterized by positive values of these indicators. For the third factor of the second level, the subgroup with a positive perception (60%) is also larger than with a negative one (40%), but not so much. The affective component of students ' attitudes towards friendship gives a completely different picture. Here, 57% of respondents are characterized by an almost neutral emotional attitude to it, while only 29% are positive. All this suggests that in the group as a whole, students position a more positive relationship to friendship on a cognitive level than they actually feel emotionally. We associate this with the influence of society (both the immediate environment in direct communication, and through literature, art, mass media, etc.). The paper also analyzes the relationship between cognitive and affective attitudes to friendship at the individual level. In General, there is no such connection for the studied audience, even statistically (the correlation coefficient is only 0.17). But if we divide the entire audience into two subgroups, characterized by both the excess of cognitive perception over affective, and with the opposite ratio, then for them separately there is already a positive statistical relationship.

  • Declarative and real perception of friendship by DSTU students Part I

    The work consists of two parts and is devoted to a comparative analysis of the declared cognitive and actually perceived affective relations to friendship. It is based on the results of a pilot survey conducted at DSTU at the end of 2019, in order to comprehensively measure the two components of students ' friendly attitudes. In the first part of the work, the rationale for the need for such complex measurements is given, and the method used to identify the cognitive component that we associate with the declared attitude is briefly shown. The results of the hierarchy of factors that describe various aspects of the structure of the cognitive perception of friendship are presented. It is found that the primary 11 characteristics that were used for the survey in the questionnaire are statistically dependent, and at the next level they are reduced to three indicators: moral relationships in friendship, interpersonal interaction in friendship, and the impact of friendship on life in General. At the higher level, these factors, in turn, are reduced to one integral indicator of the cognitive perception of friendship. The distribution functions by respondents for all these factors are given in the next part of the paper. Where they are used for comparative analysis.

  • The perception of the phenomenon of friendship students DGTU: the affective aspect of

    The work is devoted to the development of experimental research technology for the emotional component of students ' attitudes towards friendship. Using a concrete example, it is shown that the previously developed method of measuring the affective component of various social attitudes makes it possible to identify the levels of emotional perception of both real and virtual friendship. It was found that just over half of the studied audience (57-59%) showed an almost neutral emotional attitude to both real and virtual friendships. Only about 29% perceive real friendship positively, and even less – 19% - virtual friendship. On the contrary, virtual friendship is negatively evaluated by 22% , while real friendship is only 14%. Thus, in the group as a whole, the attitude to real friendship is more positive than to virtual one. It is shown that this pattern is observed not only at the group level, but also at the individual level. But in the form of a trend. The results confirm the decrease in the importance of friendship noted in the literature (compared to the last century), and the emerging increase in the role of virtual interpersonal relationships.

  • Spectrum density of the first zone of linear coupled oscillators Part II

    The aim of this work is to estimate the density of the electron spectrum of objects with a dispersion bond, such as liquid helium, for example. The interest in its electronic properties is caused by the recently discovered dynamic polarization in the second sound wave, which made the study of its zone structure relevant. In this paper, the objects under study are modeled after born by a linear chain of coupled oscillators. The dispersion bond is considered on the basis of the quasi-classical London approximation, which takes into account the correlations of the oscillating dipole moments of atoms. The first part of the work is preparatory. A brief review of the new experimental data for helium II is given, and the problem statement is formulated. On simple examples (lines of two and three coupled oscillators) the research methodology is worked out. This section is of independent importance for rapid estimates of the density of the electron spectrum in dispersion coupling, and identifies trends in the change of spectrum parameters with an increase in the number of structural units. It is obtained, in particular, that the band width increases and the specific binding energy decreases slightly. In the second part, a long chain of coupled oscillators is investigated on the basis of the developed techniques. The density of the electron spectrum is calculated both for specific chains and in the thermodynamic limit. The results obtained in this work are planned to be used in the future for the development of dynamic polarization models for helium II

  • Emotional attitudes of the students of Grozny: affective component

    The paper presents the results of measuring the overall emotional state of students in Grozny at the beginning of 2016. This characteristic is one of the indicators of social health of the study group, in particular, in relation to the political field. It is based on a pilot survey conducted among 141 students of the Grozny state oil technical University. By gender and national composition, the sample was approximately the same as in the entire educational institution. To measure the affective component of the emotional state, the method of the semantic differential of CH. Osgood was used. The interpretation of the results obtained was based on the Coombs ideal point theory, based on the proximity in the semantic space of the image of a real object from the images of ideal constructs. The distribution functions of the affective level of the emotional state are calculated in a linear approximation, as well as in the framework of the previously developed stochastic nonlinear psychosemantic phenomenological model. It was found that 14 % of respondents are characterized by a neutral emotional state, and 55% - positive. Of these, 33% reported their condition as slightly positive (a level of 0.1 to 0.3 on a scale of -1 to +1), and 22 % reported a steady positive (a level of 0.4 to 1). Negative emotional state was observed in 31 % of the respondents, of which 20 % - slightly negative (level from -0.1 to -0.3), and 11 % - stable negative (level -0.4 and below). The latter are the subgroup of risk in which social and political tensions can develop. The core of this subgroup is formed by 5 % of respondents who showed an extremely negative emotional state, with a level of -1. The results obtained differ slightly from similar data measured among students in Rostov-on-don around the same time period. For students of Grozny, the group of respondents with a positive emotional state is 10% more than for Rostov residents.

  • Internal structure of cognitive component of students ' perception of propaganda

    The work is based on experimental data obtained during the pilot survey of students of DSTU at the end of 2018. Cognitive components of perception of propaganda were revealed by direct survey, students were asked to characterize the fairness of the policy pursued by the state and the reliability of both Pro-government and opposition political propaganda in General. At the same time, domestic and foreign policies were considered separately. The correlation analysis carried out on these six indicators showed their significant mutual influence. To identify the integral characteristics behind this correlation, we used the method of hierarchy analysis, previously proposed by us such a variety as hierarchical factor analysis. It was found that at the second level, the primary six indicators are reduced to two factors, the indices of perception of missile defense and illegal propaganda. At the third level, the latter two form an integral factor characterizing the cognitive component as a whole. For each level, the priorities of the underlying indicators relative to the upper one are calculated, and the matrices of paired comparisons, both primary characteristics and intermediate ones, are restored. In addition to the internal structure indicators, the paper presents external ones, such as the distribution of the obtained factors of the second and third levels by respondents.

  • Global and local public perception of propaganda

    The probabilistic model of perception of concrete propaganda information is presented. Previously, such a model was developed by us for subjects with a neutral attitude to propaganda in General. Now it is generalized to the case of arbitrary relation. In the model, the perception of a particular news is stochastic in nature, and in the limit goes to the levels of complete reliability or complete unreliability. At the same time, there is a connection between the level of global perception of propaganda as a whole and the levels of local perceptions averaged over the entire previous ensemble of specific news . On a concrete example it is shown that the offered model allows to restore for any investigated group dynamics of local perception of concrete information on known functions of distribution of global perception. This information is important to identify the features of perception, depending on the external and internal characteristics of the study group. In addition, the model presented in this article is the basic one. One of its purposes is to serve as a basis for further expansion along the way of taking into account the impact of the social environment. That is supposed to hold in the future.

  • A new type of vortex-free flows of helium II in a rotating cylinder

    Within the framework of the two-fluid Landau theory, flows into helium II inside a rotating cylinder are investigated. Special attention is paid to the analysis of excitation by centrifugal forces of counter-current (by super-fluid and normal components) flows. In the approximation of incompressible fluid, an analytical solution of the equations of motion, vortex-free for both components is obtained. The tangential velocities for it are the same as those of a rotating solid body, with the normal and superfluid components moving in opposite directions, with different angular velocities. It's resulting vorticity is compensated by a spiraled counter-current radical movements. Such solution has no axial symmetry and has a tangential gap along the radius. Despite its instability, it is of some interest. First, it can be corrected by stabilizing deformations. In addition, it shows the paths of loss of stability of high-symmetric States. In particular, in our opinion, this type of disturbance are intermediate flow from Landau (superfluid component is at rest) one to the rotation of the Feynman type (in the superfluid part of a system of vortices).

  • Cognitive components of attitudes of students of DSTU in relation to the promotion

    At the end of 2018, a pilot survey of DSTU students was conducted to identify their perception of propaganda in General. In total 169 respondents of 1 - 4 courses, age from 17 to 37 years were interviewed. Of these, 96 people were technical specialties, 73 were humanitarian. The paper presents the results obtained by the cognitive block of the questionnaire. It asked students to describe the fairness of the policy pursued by the state and the credibility of both government and opposition political propaganda in General. At the same time, domestic and foreign policy were considered separately. Diagrams of the distribution of these six values by respondents are given. It is received that in General on the investigated group the assessment of justice of policy of the state can be called rather negative. For domestic policy, 70% of respondents indicated a level of justice below the average, 36% of them consider it completely unfair. For foreign policy, these figures are 10% better. Approximately the same regularities are observed for assessing the reliability of political propaganda, both Pro-government and opposition. At the same time, about 10% consider opposition propaganda to be more reliable.

  • A simulation model of the perception of propaganda

    This study examines the dynamics of the perception of individual segments of the advocacy news. A probabilistic-stochastic approach for simulation is proposed. As the main actor describing the situation, the probability of a positive assessment of the veracity of the new information by a separate subject is taken. For the description of the process of forming the relation to it the discrete-event paradigm is chosen. The change in the level of evaluation occurs under the influence of random perturbations of the individual's opinion, experienced at discrete moments of time. An intuitive recalculation after this perception of the news is modeled based on Bayes ' theory of decision making. Mathematically, this approach fully coincides with the previously used by us in the numerical analysis of the resolution of intrapersonal conflicts. The results revealed at that time were adapted to study the dynamics of the perception of propaganda news by a neutral part of the population. Which is made by the individuals estimating truthfulness of propaganda activity as a whole neutrally, at the level of ½ (on a scale from 0 to +1). It is found that when assessing specific news such neutrality is violated, in the end, the individual believes the news is either completely true or false. But it is already being restored at the level of the ensemble of all news. About half of them are considered by the individual to be true, half – false. The time before the formation of the final perception of a particular news depends on the degree of its importance for the subject, and the minimum is observed at the level of significance slightly below the maximum. The model of taking into account the social environment in the resolution of intrapersonal conflicts has also been adapted for the analysis of the perception of propaganda information. While the assessments of the credibility of the individual stories of neighbors are correlated. Over time, clusters with the same perception are formed in society. Ideally, in the absence of other influences, eventually one opinion is formed in the whole study group. Here again, for some propaganda news, the neutrality of perception is broken, but it is restored at the level of the ensemble of all news. The proposed models can be used to study not only the neutral part of the population, but also groups with any level of assessment of the truthfulness of propaganda in General, both homogeneous and heterogeneous in this parameter. In addition, the proposed approach can serve as a basis for the study of the impact of agents of influence (in the information space) and the development of advocacy strategies.

  • Counter-current flows in rotating helium II

    The paper discusses the flow induced by centrifugal forces in helium II on the outside of the rotating cylinder. The analysis was carried out in the framework of Landau's two-fluid theory, in the approximation of a plane incompressible fluid. A two-parameter family of solutions of the equations of motion is revealed, in which the centrifugal forces for the normal component are fully compensated by counter-current (normal and super-fluid components) flows. According to preliminary estimates, the most stable of them is the flow, in which the pressure forces in the superconducting part are also compensated, The results show that in the analysis of helium II rotations it is necessary to take into account countercurrent instabilities.
