The article considers the issue of performance of male weightlifters at the World Championships, which took place in Pattaya, Thailand on September 18, 2019. The level of competition depending on the category, the density of sports results in the top ten athletes in percent and kilograms are analyzed. It was found that the highest density was observed in the category up to 89 kg, where the difference between tenth and first place was 17 kilograms. The lowest density of results was observed in the category 109+ kg, where the difference between the first and tenth place was 64 kg. In percent, t he highest density was observed again in the category up to 89 kg - 5%. The next category - up to 67 kg, where the first place by 7% with a better result than the tenth. Categories up to 73 kg, up to 81 kg, up to 102 kg have the same figure - 8%. The largest difference in the results in percentage in the category up to 55 kg - 18%. There is a gradual increase in results, with an increase in weight categories. However, in medium weight categories, the rate of increase in results is not as rapid as in light and heavy weight categories.

Abstract Introduction. The snatch technique is a discipline in Olympic weightlifting. The lifter has to raise the barbell from the platform directly above their head in one movement. While reviewing the literature on biomechanical analysis of the techniques of weightlifting, one can find positions on the analysis of parameters, such as barbell track, horizontal displacement, and angular positions of the joints in the individual phases of the lifter's movement. Many texts concern female and male lifters taking part in World or European Championships. The parameters of the best competitors are outlined - mostly those who finish in the top five places in competition. Mostly these are parameters regarding male lifters, and less frequently those of female lifters. In the literature review, an overlooked aspect is that of the definition of the diversity of indicators as regards the snatch technique practiced by female lifters depending on score. Material and methods. In the research, registered snatch attempts during the World Championship were used. Videos were used by judges to establish a maximum weight limit for female lifters. The attempts were registered by two cameras and were later digitally processed by the APAS 2000 system. Barbell parameters, maximum speed, average of the bar, and the parameters of the lifter-bar collocation (horizontal displacement of barbell weights and height elevation) were assessed. Results. The analysed attempts show the margin of error for measurement of the average speed of the barbell as 0.03 m/s. The difference in maximum speed of analysed attempts is 15%. The height of clearance of the first-placed female lifter's barbell was 12.7 cm, 30 cm for the last-placed. Conclusions. The sporting level of weightlifting by female lifters influences the analysed biomechanical indicators of the snatch. Those indicators, which are similar in the case of both the World Championship winner and the female lifter who came last, may be described as the average speeds of the barbell. The high sporting level of female lifters performing heavy lifting is characterized by the clearance of the barbell.

Purpose: to analyze the indicators of the competitive activity of judokas in light weight categories during the World Championship among adults in 2021. Material and methods. During the work, the following research methods were used: analysis and generalization of scientific and methodological literature; timing; analysis of protocols and video recordings of fights of highly qualified judokas in weight categories up to 60 and 66 kg, methods of mathematical statistics. 49 fights of judoists in the weight category up to 60 kg and 61 fights in the weight category up to 66 kg during the World Judo Championship among adults 2021 (Hungary, Budapest) were analyzed. Results: the analysis of the received comments of highly qualified judokas of light weight categories shows that most of the comments were received by the athletes for not wrestling (up to 60 kg – 35 %; up to 66 kg – 36 %), for avoiding capture (up to 60 kg – 21 %, up to 66 kg – 27 %), the use of false attacks (up to 60 kg – 16 %, up to 66 kg – 13 %) and for fighting in a defensive position (up to 60 kg – 4 %, up to 66 kg – 6 %). The analysis of technical actions of highly qualified judokas of light weight categories made it possible to reveal the total number of effective actions. So, in the weight category up to 60 kg, athletes performed 59 effective technical actions, including 48 (81 %) in a standing position and 11 (19 %) in a parterre and lying position. Moreover, in the stand, 36 (75 %) actions were assessed by the judges for «Vasari», and 12 (25 %) for «Ippon». In the parterre and lying position - 3 (27 %) for «Vasari», 8 (73 %) for «Ippon». In the weight category up to 66 kg, athletes performed 57 effective technical actions, including 50 (87 %) in a standing position and 7 (13%) in a parterre and lying position. 38 (76 %) actions in a standing position were assessed by the judges for «Vasari», 12 (24 %) for «Ippon». In the parterre and lying position - 1 (14 %) for «Vasari», 6 (86 %) for «Ippon». Also, the main effective technical actions were identified, which are most often used by athletes in a standing position, a parterre position and lying down. So, for athletes in the weight category up to 60 kg, these are: throw over the back from their knees (19 %), grab (11 %), grab from the inside (11 %), unbalance by pushing back (11 %), elbow lever (46 %), hold on top (36 %), hold across (18 %). In the weight category up to 66 kg, the most often performed such effective technical actions were pick-up from the inside (14 %), unbalance with a push back (12 %), throw over the back from the knees, through the chest with a deflection (8 %), hold across, hold from the side heads (29 %). Conclusions. It has been established that athletes of light weight categories in most cases conduct reconnaissance battles, use defensive positions, false attacks in order to catch an opponent on a mistake. When conducting fights in this manner, they most often receive comments on not fighting, avoiding capture, using false attacks and for fighting in a defensive position. It was revealed that the struggle of athletes of light weight categories mainly takes place in the standing position. Technical actions in the parterre position and lying are more effective. Sportsmen of two weight categories used the following technical actions in a standing position more: throws over the back (from the knees, grabbing an arm on the shoulder), grabs, holds, unbalance by pushing back. In the parterre position and lying position, athletes of two weight categories used different types of holdings and the elbow lever more. Keywords: judo, athletes, competitive activity, indicators, highly qualified, light weight categories.

Aims: It is known that along with the traditionally considered amplitudes and durations of ground vibrations, the rate of increase in the intensity of ground vibrations in time can also affect the level of macroseismic effects caused by earthquakes. According to the previously obtained correlations, the differences between the observed macroseismic effects during earthquakes with slow and fast increases in the amplitude level of oscillations can reach one point of the macroseismic scale. The purpose of these study is to obtain, on the basis of a significantly (almost 9 times) larger than before, the volume of initial data (in combination with a more effective method of analysis) new and more accurate quantitative estimates of the studied dependences, as well as their possible interpretation. Background: The work continues the research began in 1985-1989. A representative statistical material was used, including 1250 accelerograms of earthquakes that occurred in different regions of the world, with magnitudes M = 2.5-7.7, distances of 5-230 km and independent estimates of macroseismic intensities I = 3-10 points by the MSK or MMI. Objective: Correlations between the absolute and relative rates of increase of ground vibration accelerations during earthquakes with different magnitudes and distances, on the one hand, and macroseismic effects caused by these vibrations, on the other, are considered. Methods: The study was carried out in the form of a direct statistical comparison of the parameters describing the form of ground vibrations during earthquakes with the characteristics of variations in macroseismic effects caused by these vibrations. A sample was formed and analyzed, including 1250 accelerograms of sensible and strong earthquakes recorded in various regions of the world and having independent estimates of the macroseismic intensity of shaking at instrumental registration sites. Results: It is shown that the macroseismic intensity of shaking can depend on the relative rate of increase of acceleration amplitudes in the general wavetrain of ground vibrations. An increase in the macroseismic intensity of shaking was observed with an increase in the relative rate of increase of the amplitudes and, conversely, it decreases with a slowdown in the rate of increase of the acceleration intensity. Similar constructions, made according to the data of the Time-Frequency Signal Analysis (TFSA) of 50 accelerograms of earthquakes with M = 3.3-6.2, a distance of 7-139 km and a macroseismic intensity of 4-7 MMI points, showed the same dependence, but clearer and with large coefficients of regression and correlation. The difference between earthquakes with “fast” and “slow” accelerations in the intensity I can reach one MSK point. Conclusion: The results of this study indicate that the rate of increase in the acceleration of ground vibrations during earthquakes can in a certain way affect the macroseismic effects. Earthquakes with slowly increasing amplitudes of ground vibration accelerations form average less macroseismic effects than those with rapidly growing accelerations. Variations in the shaking intensity, at the same time, are quite significant and can be compared with variations associated with differences in soil-geomorphological conditions, focal mechanisms, general seismotectonic conditions and other factors that are traditionally taken into account in detailed assessments of seismic hazard. Therefore, this factor should also be taken into account when conducting such studies.

The phenomenon of economic growth is studied by economists and statisticians in various aspects for a long time. Economic theory is devoted to assessing factors of growth in the tradition of R. Solow, R. Barrow, W. Easterly and others. During the last quarter of the century, however, the institutionalists, namely D. North, D. Wallis, B. Weingast as well as D. Acemoglu and J. Robinson, have shown the complexity of the problem of development on the part of socioeconomic and political institutions. As a result, solving the problem of how economic growth affects inequality between countries has proved extremely difficult. The modern world is very diverse in terms of development level, and the article offers a new approach to the formation of the idea of stylized facts using cluster analysis. The existing statistics allows to estimate on a unified basis the level of GDP production by 174 countries of the world for 1992—2016. The article presents a structured picture of the world: the distribution of countries in seven clusters, different in levels of development. During the period under review, there was a strong per capita GDP growth in PPP in the middle of the distribution, poverty in various countries declined markedly. At the same time, in 1992—2016, the difference increased not only between rich and poor groups of countries, but also between clusters.

A human-centred approach to the environment is leading to ecological collapse. One of the ways that speculative realism challenges anthropomorphism is by taking non-human things to be as valid objects of investivation as humans, allowing a more responsible and truthful view of the world to take place. Brian Willems uses a range of science fiction literature that questions anthropomorphism both to develop and challenge this philosophical position. He looks at how nonsense and sense exist together in science fiction, the way in which language is not a guarantee of personhood, the role of vision in relation to identity formation, the difference between metamorphosis and modulation, representations of non-human deaths and the function of plasticity within the Anthropocene. Willems considers the works of Cormac McCarthy, Paolo Bacigalupi, Neil Gaiman, China Miéville, Doris Lessing and Kim Stanley Robinson are considered alongside some of the main figures of speculative materialism including Graham Harman, Quentin Meillassoux and Jane Bennett.

High culture is a collection of ideologies, beliefs, thoughts, trends, practices and works-- intellectual or creative-- that is intended for refined, cultured and educated elite people. Low culture is the culture of the common people and the mass. Popular culture is something that is always, most importantly, related to everyday average people and their experiences of the world; it is urban, changing and consumeristic in nature. Folk culture is the culture of preindustrial (premarket, precommodity) communities.

International potential and consequent greater competition in belt wrestling increase the significance of assessing quantitative and qualitative indicators of competitive activity of the strongest wrestlers in the world. It is important to identify the sport development trends and to search for effective ways and tools for achievement of the sport excellence. Purpose: to reveal the features of efficient competitive activities of the world leading wrestlers on the basis of analysis of group differences in technical and tactical excellence indicators. Materials and methods of research. We analyzed videos of 285 events with participation of 197 wrestlers competing at the Belt Wrestling World Championship 2019 in Kazan. We registered the following indicators of competitive activity: the total and average number of fighting techniques, including techniques executed to the right and to the left side within 4 minutes of combat; number and types of technical actions of competition winners among men and women. Research results and discussion. The paper focuses on the comparative analysis of technical and tactical skills of men and women, the winners of the Belt Wrestling World Championship. The research revealed distinguishing features of the winner’s technical toolkit including the diversity of technical and tactical actions, a balance in the knowledge of the right and left-handed techniques. At the same time, the analysis of technical and tactical actions in women wrestling shows the backlog of female athletes in these components of technical fitness.


Dreyfus argues that there is a basic methodological difference between the natural sciences and the social sciences, a difference that derives from the different goals and practices of each. He goes on to argue that being a realist about natural entities is compatible with pluralism or, as he calls it, “plural realism.” If intelligibility is always grounded in our practices, Dreyfus points out, then there is no point of view from which one can ask about or provide an answer to the one true nature of ultimate reality. But that is consistent with believing that the natural sciences can still reveal the way the world is independent of our theories and practices.
