    Purpose. The research is aimed at determining the influence of negative ethical emotions on social life and the activity of the individual, which involves solving the following problems: a) to find out approaches to the typology of ethical emotions, b) to highlight individual negative ethical emotions and to determine their ability to influence human behaviour. Theoretical basis. The theoretical and methodological basis of the research is the recognition of the significant influence of negative emotions on human activity in society. In this regard, it is proposed to consider them as a complex multidisciplinary phenomenon, which is predetermined by both social and personal factors of origin and has a certain specificity of objectification. Originality. The authors determined that in addition to destructive effects on a person of negative emotions, they can also have a constructive effect on person’s behaviour, due primarily to the fact that a person does not want to experience these emotions and therefore tries to avoid situations they cause. Conclusions. The ethical emotions of guilt, embarrassment, anger, disgust and contempt can affect, through the cognitive aspect of the emotional process, the decision-making process of people when they predict situations in which they risk to feel such emotions. So the emotion of guilt creates a constructive setup aimed at correcting inappropriate social norms of human behaviour. The emotion of embarrassment motivates a person to behave more benevolently in society in order to integrate in it and get its approval, thus encouraging the person to adhere to social and moral agreements and norms. The emotion of anger motivates a person to act to eliminate injustice, herewith not only in relation to himself, but also in relation to others. Rejecting those people who cause moral and social aversion, society creates a system of punishments and rewards that acts as a strong deterrent to the socio-cultural behaviour. The emotion of contempt performs the function of preventing punishment in relation to the despised individual

    Mathematical modeling of thermal stabilization of vertical wells on high performance computing systems

    Temperature stabilization of oil and gas wells is used to ensure stability and prevent deformation of a subgrade estuary zone. In this work, we consider the numerical simulation of thermal stabilization using vertical seasonal freezing columns. A mathematical model of such problems is described by a time-dependent temperature equation with phase transitions from water to ice. The resulting equation is a standard nonlinear parabolic equation. Numerical implementation is based on the finite element method using the package Fenics. After standard purely implicit approximation in time and simple linearization, we obtain a system of linear algebraic equations. Because the size of freezing columns are substantially less than the size of the modeled area, we obtain mesh refinement near columns. Due to this, we get a large system of equations which are solved using high performance computing systems.Comment: 9 pages, 5 figure

    Perception of Dynamic Social and Non-social Stimuli in Preterm and Full-term Children: Neurocognitive Correlates in Early Childhood

    Get PDF
    Preterm birth is the leading cause of newborn deaths in almost all countries around the world. Whilst survivors encounter severe motor, cognitive and behavioral impairments during infancy or later in their lives, the studies of the recent years have demonstrated that the social development serving a basis for learning and cognition of the environment in human infants can be severely affected even in normally developing preterm born children (gestational age < 37 weeks). The current article presents a discussion on the behavioral as well as the neuroimaging aspects of the social maturation in preterm and full-term children, depicting complexity of theimpairments and focusing on the involved brain structures. Further, authors perform the design of the longitudinal study of social and non-social perception in early childhood, implemented on the base of the Laboratory for Brain and Neurocognitive Development (Ural Federal University). Keywords: prematurity, social development, early childhood, neurocognitive correlate

    The oxygen-atom transfer reaction from the bis(µ-oxo)dicopper(III) complex [CuIII2(µ-O)2(L)2]2+1, where L =N,N,N,N -tetraethylethylenediamine, to PPh3 has been studied by UV-vis, EPR, 1H NMR and Cu K-edge X-ray absorption spectroscopy in parallel at low temperatures (193 K) and above. Under aerobic conditions (excess dioxygen), 1 reacted with PPh3, giving OPPh3 and a diamagnetic species that has been assigned to an oxo-bridged dicopper(II) complex on the basis of EPR and Cu K-edge X-ray absorption spectroscopic data. Isotope-labeling experiments (18O2) established that the oxygen atom incorporated into the triphenylphosphine oxide came from both complex 1 and exogenous dioxygen. Detailed kinetic studies revealed that the process is a third-order reaction; the rate law is first order in both complex 1 and triphenylphosphine, as well as in dioxygen. At temperatures above 233 K, reaction of 1 with PPh3 was accompanied by ligand degradation, leading to oxidative N-dealkylation of one of the ethyl groups. By contrast, when the reaction was performed in the absence of excess dioxygen, negligible substrate (PPh3) oxidation was observed. Instead, highly symmetrical copper complexes with a characteristic isotropic EPR signal at g= 2.11 were formed. These results are discussed in terms of parallel reaction channels that are activated under various conditions of temperature and dioxygen
