Tráfico de internet y desempeño de las empresas en sectores de alto costo: hay dos caras de la moneda

En el contexto de la digitalización de la economía ha aumentado la importancia de los sitios web de las empresas, bien establecidos y fáciles de usar. La pandemia de COVID-19 se ha convertido en un nuevo motor para el desarrollo de las comunicaciones por internet entre fabricantes y consumidores. Este artículo explora la relación entre el tráfico de internet de los sitios web de las empresas y sus volúmenes de ventas y rentabilidad. Aplicamos el análisis de regresión de datos de panel y modelo de regresión de Prais-Winsten con ajuste de error estándar de panel, que proporciona estimaciones conservadoras y confiables. Sobre la muestra de 268 observaciones extraídas de 67 empresas rusas que operan en las industrias de gran valor de la fabricación de automóviles y el desarrollo inmobiliario durante el período 2017-2022 caracterizado por un gran impacto exógeno, demostramos que el tráfico de internet ejerce un efecto positivo en la empresa. Al mismo tiempo, este efecto positivo sobre las ventas va acompañado de un efecto negativo del tráfico de internet sobre la rentabilidad de la empresa. El efecto negativo sobre la rentabilidad es particularmente pronunciado para las empresas más jóvenes que probablemente enfrenten severas limitaciones de recursos y, por lo tanto, puede decirse que sacrifican la rentabilidad para asegurar las ventas. En esta situación, la aplicación de estrategias rentables puede ser fundamental para las empresas más jóvenes. Las empresas más jóvenes deben prestar especial atención a los contenidos de sus sitios web para asegurarse de que proporcionen suficiente información adecuada que ayude a ganar la confianza de nuevos clientes.//The importance of well-established and customer-friendly firms’ websites has increased in the context of the digitalization of the economy. The COVID-19 pandemic has become a new driver for the development of Internet communications between manufacturers and consumers. This article explores the relationship between the Internet traffic of companies’ websites of and their sales volumes and profitability. We apply panel data regression analysis and model of Prais–Winsten regression with panel standard error adjustment, which provides conservative and reliable estimates. In the sample of 268 observations drawn from 67 Russian firms operating in the big-ticket industries of car manufacturing and real estate development during the period of 2017- 2022 characterized by a major exogenous shock, we demonstrate that internet traffic exerts a positive effect on firm sales. At the same time, this positive effect on sales is accompanied by a negative effect of internet traffic on firm profitability. The negative effect on profitability is particularly pronounced for younger firms that are likely to face severe resource constraints and can thus be said to sacrifice profitability to ensure sales. In such situation, application of cost-effective strategies may be critical for younger firms. Younger firms should pay particular attention to the contents of their websites to ensure that they provide enough adequate information that will help win the trust of new customers

Neural network analysis of electroencephalograms based on their graphical representation

The article is devoted to the problem of recognition of motor imagery based on electroencephalogram (EEG) signals, which is associated with many difficulties, such as the physical and mental state of a person, measurement accuracy, etc. Artificial neural networks are a good tool in solving this class of problems. Electroencephalograms are time signals, Gramian Angular Fields (GAF) and Markov Transition Field (MTF) transformations are used to represent time series as images. The paper shows the possibility of using GAF and MTF EEG signal transforms for recognizing motor patterns, which is further applicable, for example, in building a brain-computer interface

Main problems caused by inconsistency of the education system and labor market needs were revealed. The study of the educational expectations and needs of graduates and students (using questionnaires) was made herein. Labor market analysis wad done to show the main negative and positive aspects of its development. Market industry forecast trends and the education market tendency for the next few years were built to reveal disproportion of the industry needs and educational system outcomes

Well-Being Indices Comparative Analysis: Russia And Foreign Countries

Using the OECD’s data, we study well-being indices comparison main areas for Russia and economically developed countries. The tendency of unleading countries to find mechanisms of economic growth by the welfare various aspects impact is noted. We used the method of complex efficiency estimation to solve the problem of economic well-being analysis. We assessed the effectiveness and optimality of economic well-being of the population. The effectiveness assessment of economic well-being in Russia revealed a significant gap from foreign countries by most indices. The optimality assessment of economic well-being did not reveal any major differences in values between men and women both in Russia and in foreign countries, but allowed to establish a greater gap between the values of indicators of leading and lagging groups in Russia than in other countries. Indicators ratio of lagging groups in Russia with foreign countries was worse than the ratio of indicators at the entire population level. The results of the economic well-being analysis are advisable to consider in the process of state regulation in Russia. State support of social services should be a priority of social and economic policy on the federal and regional authorities. Our analysis justifies the recommendation to reduce the gap between rich and poor groups of Russia's population by using various regulatory tools, including a progressive scale for a number of taxes

The peripheral hemodynamics of the lower extremities of powerlifters

Objective: to study the features of peripheral hemodynamics of the lower extremities of powerlifters depending on their experience and qualification. Materials and methods: the study of cardiovascular systemwas conducted in 38 men aged from 18 to 25 years engaged in powerlifting. 20 participants had sports categories (1-3) and 18 participantswere candidates or masters of sports. To study the regional blood flow in the areas of «foot», «calf» and «hip» the hardware and software complex «Reo-Spectrum-3» of «Neuro-Soft» were used. Results: significant decrease in the amplitude of the systolic wave, the arterial wave, the maximum systolic value of the venous component of the hip of powerlifters was revealed in comparison with the control group. A significant decrease in the amplitude-frequency index of powerlifters was also revealed. The index of fast filling was significantly lower in powerlifters. The values of the «inflow-outflow»ratio pointed at the change of the tonus of vessel wall in powerlifters. The average speed of slow filling indicated a decrease in the tonus of small and medium arteries in powerlifters. The change in vascular tone in powerlifters indirectly indicated a shift in the autonomic balance towards the predominance of sympathetic influences.All parameters showed an increased stress of the mechanisms of regulation of cardiac activity. Conclusions: the nature of blood circulation shifts includes changes in both the arterial and venous parts of the blood stream. The most pronounced changes in peripheral blood circulation were found in the areas of «calf» and «foot». With the growth of sports skills, the nature and degree of vascular changes increases, which indicates a decrease in the adaptive capacity of the vascular system of the lower extremities to intense physical activity
