Human Identity as Freedom Statement in the Philosophy of Child Education

The purpose of this article is to reveal the specific features of personality-oriented education and to consider how a person, being in dialogue with another person, can declare freedom only by an act of own free will. To achieve the goal set, the authors have used a set of theoretical and empirical methods of analysis, description, comparison, extrapolation, synthesis, hermeneutic methodology, and a method of implication. Cross-sectional studies and case studies have also been used at the intersection of philosophy and psychology. It is emphasized that in the Ukrainian framework of the representation, this problem demonstrates the following – the “old” system of education, formed on the principle of necessity, has demonstrated its inef- fective mechanism of action through a system of prohibitions and oppression. The “new” system of educa- tion, built on the principle of freedom, relies on its effectiveness, rejecting necessity and eliminating com- pulsion. However, the methodological error of creating something new by destroying the old and ineffi- cient is becoming more and more evident.

Analysis of temperature measuring error in high-temperature ceramic samples with various methods of thermocouple fixing

The evaluation of methodological errors in measuring the temperature of nitride ceramics under unilateral heating by high-intensity heat flow was carried out. Simulation of thermal processes in the temperature sensor — sample system was performed using the Siemens PLMNX program. Various methods of fixing platinum-rhodium thermocouples with a diameter of 0.1 mm on the surface and inside the samples have been investigated. The regularities of the influence of the size of the hot junction, the presence of thermal cement, the shape of the grooves for fixing thermocouples on the methodological error of temperature measurement were investigated. Significant errors were revealed when installing thermocouples on the surface of the sample without violating its integrity. Recommendations for the installation of thermocouples were given. The results of the paper can be useful in the preparation of experimental samples for thermal tests on radiation heating stands.

Prediction or causality? A scoping review of their conflation within current observational research

Etiological research aims to uncover causal effects, whilst prediction research aims to forecast an outcome with the best accuracy. Causal and prediction research usually require different methods, and yet their findings may get conflated when reported and interpreted. The aim of the current study is to quantify the frequency of conflation between etiological and prediction research, to discuss common underlying mistakes and provide recommendations on how to avoid these. Observational cohort studies published in January 2018 in the top-ranked journals of six distinct medical fields (Cardiology, Clinical Epidemiology, Clinical Neurology, General and Internal Medicine, Nephrology and Surgery) were included for the current scoping review. Data on conflation was extracted through signaling questions. In total, 180 studies were included. Overall, 26% (n = 46) contained conflation between etiology and prediction. The frequency of conflation varied across medical field and journal impact factor. From the causal studies 22% was conflated, mainly due to the selection of covariates based on their ability to predict without taking the causal structure into account. Within prediction studies 38% was conflated, the most frequent reason was a causal interpretation of covariates included in a prediction model. Conflation of etiology and prediction is a common methodological error in observational medical research and more frequent in prediction studies. As this may lead to biased estimations and erroneous conclusions, researchers must be careful when designing, interpreting and disseminating their research to ensure this conflation is avoided.

Improving the estimation of methodological errors in reproducing the volumetric air flow rate by reference critical nozzle

In the development of the previously obtained results a more accurate estimate of the methodological error in reproducing the volumetric air flow rate by reference critical nozzle is given, associated with the choice of the gas flow model and due to taking into account the initial kinetic energy of the flow at the nozzle inlet. Based on improved flow model an analytical evaluation of the methodological error in reproducing the volumetric air flow rate by reference critical nozzle, which is due to a change in the humidity of the working air, has been carried out. It is shown that the methodological error in reproducing the volumetric air flow rate by reference critical nozzle, associated with a change in the air humidity, as well as the analogies methodical error caused by the existence of the initial kinetic energy of the flow, must be taken part in accuracy characteristics at the real operating conditions of the standard volumetric air flow rate using critical nozzles.

Reconstructed evolutionary patterns for crocodile-line archosaurs demonstrate impact of failure to log-transform body size data

Pseudosuchia includes crocodylians, plus all extinct species more closely related to them than to birds. They appeared around 250 million years ago and have a rich fossil history, showing extinct diversity that exceeds that of their living members1-4. Recently, Stockdale & Benton5 presented analyses of a new dataset of body size estimates spanning the entire evolutionary history of this group. They quantified patterns of average body size, body size disparity through time, and rates of evolution along phylogenetic lineages. Their results suggest that pseudosuchians exhibited considerable variation in rates of body size evolution, for which they provided various group-specific explanations and asserted the importance of climatic drivers. This differs from two recent studies that analysed a substantial portion of pseudosuchian body size evolution and proposed that adaptation to aquatic life, a biological innovation of some subgroups, was the main driver of body size evolution, with patterns of disparity also being influenced by size-dependent extinction risk6,7. Here we show that the analytical results of Stockdale & Benton5 are strongly influenced by a methodological error in their body size index. Specifically, that they chose not to log-transform measurement data prior to analyses.

A Method for Assessing the State of the Snow and Ice Cover by the Brewster Angle

Introduction. Landing is the most challenging and dangerous part of the helicopter flight. The development of systems facilitating safe landing is a priority task for both Russian and foreign engineering companies. Landing on unprepared sites covered with snow and ice may be determined by the need to deliver cargo and ammunition in combat conditions, during search and rescue operations, evacuations of victims, etc.Aim. Development of a method for remote assessment of the snow and ice cover based on the results of oblique sensing of the underlying surface with a radio signal with vertical polarization.Materials and methods. In the MatLab environment, the authors conducted numerical simulations of Fresnel reflection coefficients of echo signals with vertical polarization in the 40–90 degree sensing range in the operating frequency range when solving the direct and inverse problem of reconstruction of the parameters of snow and ice layers.Results. Intervals of the Brewster angle values were obtained at which the value of the Fresnel reflection coefficient from the boundaries of the snow and ice cover takes minimal. Thus, was found to be – 47...55°, – 55...58° and – 58...61° for dry snow, dry firn and dry ice, respectively. The depth resolution when using an ultra-wideband LFM signal with a frequency from 2 to 8 GHz is about 4 cm. The methodological error in determining the dielectric permittivity of layers by the Brewster angle comprises not more than 3 %.Conclusion. The error in determining the relative permittivity and the depth of k layers under an increase in the RMS values of the noise level from 3.8 to 4.8 with a step of 0.1 for 100 implementations of each with a probability of 0.95 does not exceed 10 %, which confirms the validity of this method. The implementation of which allows you to automate the process of evaluating the possibility of a safe landing, thereby reducing the decision-making time and increasing the level of safety.

IMPROVING THE ACCOUNTING OF ADMINISTRATIVE EXPENSES OF COMPANIES ENGAGED IN MULTIPLE ACTIVITIES

Production costs and costs of selling products (works, services) are the main objects of on-farm control. Any change in them when a company conducts several activities leads to an incorrect determination of profit for each of the activities. Thus, the risk of material misstatement of production costs and sales costs increases, and hence the adoption on their basis of incorrect decisions on the future economic activities of the company. Organizationally and methodically correctly organized accounting of general business costs makes it possible to provide reliable information on the formation of the actual cost of finished products and goods. The paper analyzes unified approaches to the application of the Chart of Accounts for the financial and economic activities of organizations and the reflection of the facts of economic activity on the accounts of accounting, enshrined in the instructions for using the chart of accounts for the financial and economic activities of organizations. The analysis made it possible to identify a methodological error in the accounting of administrative and managerial expenses that arises when combining types of production activities with types of trading activities. An assessment of the information that the instructions on the use of the chart of accounts of the financial and economic activities of organizations on account 26 «General business expenses» and the actual data of the current accounting of a number of organizations that simultaneously carry out production and trade types of activities are recommended to summarize. The obtained result confirmed the overestimation of general business expenses while underestimating the costs of selling such economic entities. We see the prospect of further investigation of the problem in the elimination of the identified methodological error in accounting for administrative and management expenses with the introduction of adjustments to the instructions for using the chart of accounts of financial and economic activities of organizations.

Analysis of automotive electronic systems encoders metodological errors

Various types of encoding transducers (encoders) are used in modern technics widely to measuring the characteristics of mechanical motion which is predetermined by their reliability, operation stability and some other positive qualities. At the same time the basic operation principle of this measuring transducers type determines the presence of irremovable methodological errors in the measurements results obtained with their help. These errors reduce the efficiency of target systems. Their accounting and further compensation are possible in the presence of the mathematical apparatus for simulation of the measurement results. In this article substantiation and synthesis of this apparatus which includes the main encoder’s parameters are carried out. The generated mathematical model can be used for the selection or design of encoding transducers to electronic monitoring and control systems for automobiles, tractors as well as other self-moving machines and technical objects at all.
