Purpose: This study aimed to develop a stroke effectiveness test in table tennis based on the temporal game structure to assess the ball speed and ball placement of the players, with a purpose to analyze its reproducibility and validity. Methods: Nineteen male table tennis players participated in this study. The test was performed twice during the first session and once during the second session to assess the intrasession and intersession reproducibility, respectively. Moreover, the test was examined on its ability to (...) discriminate between regional and local performance-level players and on the relationship between the test results and the table tennis performance to assess the discriminant and concurrent validity, respectively. In general, the test consisted of 11 simulated rallies of 2–5 balls with the effort and rest ratio of 0.5, and focused on attack with offensive strokes at defensive balls delivered by a robot randomly between the left and right positions on the table. Results: Ball speed, ball placement, and ball speed-ball placement index showed satisfactory reliability and agreement outcomes. Additionally, the Bland-Altman plots show the systematic error of the analyses closer to 0, and that most values were within the limits of agreements. Concerning validity analyses, regional players had higher scores of ball placement and ball speed-ball placement index as well as made fewer errors than local players. Moreover, ball placement, ball speed-ball placement index, and percentage error presented a strong and significant correlation with table tennis performance. However, ball speed was slightly different between the regional than local players and this variable was not related to table tennis performance. Conclusion: Our findings show evidences that the test is reproducible. Moreover, discriminant and concurrent validity are confirmed for ball placement and ball speed-ball placement index. (shrink)

This paper is focused on the ways of expressing trust and distrust in financial institutions represented in the language and speech culture of the population of the Lipetsk region. Based on 55 semi-structured interviews of three generations (centennials, millennials, elder generations) living in rural and urban settlements, issues of understanding and interpretation of financial institutions, features of trust, positive and negative experiences of interaction with various financial institutions were analyzed. The use of the constructivism made it possible to interpret trust (...) as an internal component of the practices of an agent involved in the current financial situation. The study showed that in regions with an average standard of living, an average level of financial culture and the dominance of a conservative model of financial behaviour, the difference between generations is less noticeable against the backdrop of a significant difference between residents of rural and urban settlements. The analysis of interviews with three generations of residents of the region showed that the conservative model of financial behaviour continues to be reproduced in the speech culture of the informants, where banks and insurance organizations remain the most trustworthy. The images of financial institutions, represented in the language of the interviews, revealed a high level of resentment associated with the experience of past events (the collapse of the USSR, privatization). The content analysis revealed the image of the state as a “collector of payments”, and to a lesser extent, a “helper” supporting a person in his relationship with financial institutions. (shrink)

The use of the capacity method of rare events analysis [1,2] for the historical events analysis is demonstrated using the example of the Russian-Turkish wars. Modeling rare events as events of overflow of a certain capacity, for example, a cup of patience, it turns out to recover from these rare events the resulting function of the difference between incoming and outgoing disturbance flows. For different variants of representing the effect of an event, different functions were obtained, which were given an (...) interesting interpretation, as example the speed of preparation for the next war.
