Time synthesis of sensorimotor action is reviewed as a process of a coherence setting action duration (expected duration), time sequence of required operations and significant changes in conditions. Aim: to experimentally set up the connection of time synthesis success and efficiency of realization sensorimotor action in changeable conditions. Hypothesis: successful time synthesis of the setting duration and the temporal sequence of operations in the mental organization of sensorimotor action in changing conditions is realized in accordance with the corresponding operational meaning and is allowed by anticipatory effects and an increase in the effectiveness of the action, materials and methods. An experimental study involved 152 male and female students. Participants of the investigation solved experimental tasks, implemented in a computer version, according to schemes of a simple visual-motor reaction and a choice reaction (separately and in combination), according to a scheme of sensorimotor action with a warning signal when the apperceptive scheme, setting duration and sequence of required operations were changed promptly. Results were reviewed in the aspect of disclosing the features of the subject's elimination of the uncertainty of the moment of achieving the goal in the future and the construction of a sequence of operations of sensorimotor actions in a connection with changes in external conditions, typical for the time deficit regime. The conditionality of the time synthesis of sensorimotor action by the actual operational meaning was established revealing that the successful temporal synthesis of sensorimotor action in changing conditions is associated with the fastest acceptance of an adequate apperceptive scheme, with effective anticipation of the moment of achieving the goal and the formation of a detailed setting duration of action, with the formation of a temporal sequence of required operations. Conclusions. The levels of success of the time synthesis of sensorimotor action in changing conditions are highlighted: “quite successful; moderately successful; unsuccessful.”

Abstract. The success of students' adaptation to the educational process depends on individual psychophysiological features, which are manifested in the behavioral strategy. Materials and methods. The study involved 76 young males and 132 females, the average age was 21.6 ± 0.2 years. Evaluation of the behavioral strategy in conflict interaction was carried out using the method of K. Thomas; the structure of aggression was studied with the help of the A. Buss and A. Durkee hostility inventory; the level of reactive and personal anxiety was measured with Spielberger state trait anxiety inventory (Spilberger-Khanin test). The neurodynamic properties were evaluated using the results obtained in the “Simple visual-motor reaction” and “Choice reaction” test. Mathematical processing of the results was carried out using Statistiсa 6.0. The compliance of the data with the normal distribution was checked by the Kolmogorov-Smirnov criterion. Differences were considered significant at p ≤ 0.05. Results. Tuvan students revealed gender differences in behavior in conflict situations: female students mostly demonstrated an effective behavioral strategy, while male students were characterized by an ineffective behavioral strategy. Female students with a neutral behavioral strategy (16.7%) were characterized by high indices of aggressiveness and hostility and low values of reactive anxiety. A high level of personal anxiety was found in all female students regardless of their behavioral strategy. Male students with high values of aggressiveness, reactive and personal anxiety were identified in isolated cases in a group with an effective behavioral strategy. In female students, the latent period of a simple visual-motor reaction was associated with a behavioral strategy. In male students, differences in the latent period of a simple visual-motor reaction were not detected regardless of the strategies of behavior. The functional level of the central nervous system of all the students studied, regardless of the strategy of behavior, was characterized as "slightly reduced." According to the data obtained for the “stability of the nervous reaction” and “level of functionality”, gender differences were revealed. Conclusion. Neurodynamic features, the prevailing effective strategy of behavior in a conflict situation, and the structure of aggression of Tuvan female students indicate an adequate reactivity of the body, which is confirmed by a “slightly reduced” level of performance. This, probably, provides a more successful adaptation to the educational process compared to male students.

The Revolution

In 1792, the French Revolution became a thing in itself, an uncontrollable force that might eventually spend itself but which no one could direct or guide. The governments set up in Paris in the following years all faced the problem of holding together against forces more revolutionary than themselves. This chapter distinguishes two such forces for analytical purposes. There was a popular upheaval, an upsurge from below, sans-culottisme, which occurred only in France. Second, there was the “international” revolutionary agitation, which was not international in any strict sense, but only concurrent within the boundaries of various states as then organized. From the French point of view these were the “foreign” revolutionaries or sympathizers. The most radical of the “foreign” revolutionaries were seldom more than advanced political democrats. Repeatedly, however, from 1792 to 1799, these two forces tended to converge into one force in opposition to the French government of the moment.

The Moment

This theoretical paper considers the morality of machine learning algorithms and systems in the light of the biases that ground their correctness. It begins by presenting biases not as a priori negative entities but as contingent external referents—often gathered in benchmarked repositories called ground-truth datasets—that define what needs to be learned and allow for performance measures. I then argue that ground-truth datasets and their concomitant practices—that fundamentally involve establishing biases to enable learning procedures—can be described by their respective morality, here defined as the more or less accounted experience of hesitation when faced with what pragmatist philosopher William James called “genuine options”—that is, choices to be made in the heat of the moment that engage different possible futures. I then stress three constitutive dimensions of this pragmatist morality, as far as ground-truthing practices are concerned: (I) the definition of the problem to be solved (problematization), (II) the identification of the data to be collected and set up (databasing), and (III) the qualification of the targets to be learned (labeling). I finally suggest that this three-dimensional conceptual space can be used to map machine learning algorithmic projects in terms of the morality of their respective and constitutive ground-truthing practices. Such techno-moral graphs may, in turn, serve as equipment for greater governance of machine learning algorithms and systems.

In the article there are presented the results of physiological and hygienic evaluation of studies in kindergarten with the use of educational games on an electronic PC tablet. The study involved 44 foster-children. In one of the groups children in the classroom used the interactive game software on electronic PC tablets «Samsung», the same time while working with the PC tablet did not exceed 10 minutes, in the other - the classes were held traditionally. There were investigated the state of health, psychosomatic and psycho-emotional state of children, determined their functional readiness for systematic training in school, mental performance, the functional state of the central nervous system (CNS) by simple visual-motor reaction (SVMR) and reactions to a moving object (RDO). Developing of game sessions with the use of electronic PC tablets for 10 minutes were established to contribute to the activation of the central nervous system and increase in children resistance to the development of fatigue.

Although from the moment the Film Council was set up, it was clear that the intention was to found an organisation focused on bringing ‘sustainability’ to the British film industry, the Council gradually retreated from this term in favour of a wider set of priorities and the way in which it articulated its mission also gradually shifted. Drawing on a wealth of original interviews with senior politicians, film executives, independent producers, industry experts and leading filmmakers, this chapter examines the key players, forces and assumptions which drove the Film Council’s agenda, how the weighting of priorities shifted over time and why the Council’s sense of mission changed over its lifetime.

Dairy products are of great socio-economic importance in Romania today. These products have both nutritional and economic importance. The market is the economic category of commodity production in which it expresses the totality of the sale-purchase acts viewed in an organic unit with the relations it generates and in connection with the space in which it takes place. The market originated a long time ago, being related to the moment when, in order to satisfy their existential needs, "discovered" and increasingly "conscious", the people exchanged between them, respectively collectivities, the surpluses held by each individual - individually or collectively. The exchange, set up as a means of realizing its own interests, has seen various forms and has evolved continuously, being still the foundation of all the economies of the world. The market has grown based on the amplification and diversification of human needs. The satisfaction of these needs is given by the close link between producers and consumers.

The need for centimetric accuracies set by the application of the VLBI technique to geodesy implies a considerable computational effort, because of the intrinsic complexity of the model and because there is an increasingly large number of calibrations and corrections which can be accounted for only via software. The program VLBI 3 (Robertson, 1975) has been developed for the geodetic and astrometric analysis of VLBI data. It includes an accurate theoretical model of the observables and is supported by a number of routines for parameter fitting and input/output operations with data and results. The original VAX version of VLBI 3, due to N. Bartel and M.I. Ratner, runs in batch mode and requires routines which are in general unavailable in standard VAX systems. We have prepared (Caporali and Sylos Labini, 1982) a modified VAX version of VLBI 3. This version runs on our standard VAX/VMS computers and contains a number of changes in the FORTRAN source which allow to the user a real time interaction with the program. In addition, having a Tektronix graphic station at our disposal, we decided to replace the existing plot package - which used the line printer - with a “ad hoc” graphic program which permits interactive display of the results of each run of VLBI 3. Our work was mostly concerned with the input/output sections of VLBI 3. The theorical model of the VLBI observables has, for the moment, been left unchanged. We have, however, noticed that the theorical model could be updated and made more precise, e.g. in the computation of the nutation terms and of the aberration. This updating and a more extensive geodetic and astrometric analysis of VLBI data are planned to be done next.
