Published: June 2022

The purpose of the study – to describe the peculiarities of the formation of motor skills in athletes in bullet shooting at the initial stage of training.

Materials and methods. The following research methods were used to solve the tasks: analysis and generalization of scientific and methodological literature, pedagogical observations, processing of results. The analysis of the scientific and methodological literature made it possible to establish that in the technical training of young shooters the available general information is given without specifying the use of tools and methods for learning motor skills. The pedagogical observation was used to study the peculiarities of learning the technique of performing bullet shooting elements, as well as mastering motor skills.

Results. The analysis of educational and training activities allowed to determine that learning to master the technical elements of shooting athletes at the stage of initial training requires the use of modern methods and tools. A number of educational and methodological documents were analyzed: the curriculum for the training of archery for children and youth sports schools, specialized children and youth schools of the Olympic reserve, schools of higher sportsmanship and educational institutions of sports profile; specialized literature on shooter training. In the process of analysis it was determined that the technical training of athletes occupies a significant share of the duration of the training process, and requires the use of an increased arsenal of additional tools for the effective study of shooting techniques.

Conclusions. A detailed analysis of the specialized educational and methodological literature for the training of shooters revealed that in the group of initial training technical training is characterized by studying the basics of elements of shooting techniques, namely: racks for shooting, aiming, breathing, finger pressure on the trigger. Mastering these basics of the elements of shooting technique directly depends on quality and well-formed motor skills, which in the future will allow the athlete to achieve a high sports result.

Published: June 2022

Background: The current study aimed to examine the effects of combat exposure and killing on mental and subjective physical health later in life among Korean Vietnam War veterans.Methods: The data were collected from 342 male veterans with a mean age of 72 years (SD=2.57). Veterans were divided based on their histories into three groups: no experience (Group 1), combat exposure only (Group 2), and both killing and combat exposure (Group 3). Analyses of variance (ANOVAs) examined group differences in post-traumatic stress disorder (PTSD) symptoms, anxiety symptoms, hostility, and perceived physical health.Results: The ANOVAs showed that PTSD, anxiety symptoms and hostility were most prevalent among the veterans in Group 3 (both killing and combat exposure). No significant differences were found between Groups 1 and 2. Perceived physical health was highest among the veterans in Group 1 (no experience). There were no differences between Groups 2 and 3. Even after controlling for the impacts of optimism and social support after homecoming, these results were similar.Conclusions: The findings indicate that killing experience and combat exposure should be considered in designing interventions for veterans deployed into active combat zones.

EU Public Procurement Policy During Covid-19: A Turning Point for Legitimate EU Governance?
Authors: Pircher Brigitte
Published: June 2022

Public procurement is a policy area located between two contradictory tendencies. On the one hand, the European Commission strives for greater competition to widen procurement markets. On the other hand, the boosting of competition encounters resistance among the member states. This article investigates how these colliding tendencies played out during the initial stages of the Covid-19 crisis and, more specifically, how changes in the field of procurement affected legitimate governance in the EU. Based on institutionalist and EU governance theories, the study contributes to the literature with three principal findings. First, it demonstrates that the pandemic enabled exogenously driven changes in the field of public procurement with new policies and guidelines, while the EU’s overall aims in this field were upheld. Second, the study demonstrates that the Commission was the main driver of change and that it enhanced the harmonisation of procurement rules and supranational integration despite the crisis. Third, while these changes strengthened the role of supranational actors, the study demonstrates that the changes introduced allow member states increased flexibility when it comes to the implementation. In practice, however, this flexibility has the potential to undermine the EU’s initial aims, thereby jeopardising the EU’s legitimacy.

Authors: Shcherbakova Alexandra I.
Published: June 2022

The paper presents a study of the process of forming and instilling economic culture in cadets of higher military and technical educational institutions of the Russian Federation in conditions of uncertainty. The relevance of scientific research in this area is justified, confirmed by the results of surveys, as well as research in the implementation of educational programs in the discipline Economics. The contradictions that justify the need to apply new slants in the formation of economic culture, a significant component of the culture of the individual, are revealed. The analysis of scientific sources on this subject is made, which allowed us to characterize the main structural elements of the economic culture of the individual, to form a conceptual apparatus, to study the interpretation of the main terminology in foreign and domestic literature. The application of innovative methods in the field of teaching the discipline, such as a personalized approach, is proposed, which can be used together with basic educational technologies in the process of training in a military educational institution. The article describes the variable resolution of problems and contradictions of a methodological and organizational nature. The use of the proposed options will create a cluster model of the gradual formation of economic culture. The paper presents the pedagogical conditions for the successful implementation of the developed model of instilling economic culture in cadets of higher military educational institutions, allowing to take into account the degree of preparedness of various groups of students, directing them to the assimilation of motivational attitudes of self-development and self-realization. The aspects of using a personalized approach in the process of forming the economic culture of cadets of a special faculty are considered. The results of the application of this approach, while providing the educational process at the special faculty of the Mikhailovsky Military Artillery Academy (St. Petersburg), are presented. Possible directions and ways of solving the identified problems are proposed, which will allow raising the content aspect of educational programs to a higher level and, as a result, the level of knowledge, skills, attainments and competencies of this area, as well as the process of forming an economic culture.
Purposefulness and spontaneity as properties of self-organization of thinking
Authors: Dautov Denis F. , Belousova Alla K.
Published: June 2022

The paper describes thinking as a complex self-organizing system that simultaneously demonstrates such properties as spontaneity and purposefulness. Such an idea of thinking allows us to consider the specific components of thinking involved in its self-organization when processing arrays of information. This is of particular interest for improving tactical and strategic training methods. The main theories of self-organization are described and analyzed. Among the presented theories devoted to the problem of self-organization, special attention is paid to the theory of complex thinking and the theory of autopoiesis, the cybernetic and synergetic approach, the theory of dissipative structures. The description of thinking and related phenomena was based on the theory of cognitive structures, mental models and the theory of double coding. The features characteristic of theories postulating the spontaneous or purposeful nature of complex self-organizing systems are generalized. It is proposed to use a number of general provisions of self-organization theories to describe the processes and structures of thinking. Attention is drawn to the role of verbal and nonverbal components of thinking in its self-organization when working with information. The features of processing symbolic and figurative information at the verbal and non-verbal level are considered. Attention is drawn to the correlation of the conscious and unconscious in the human psyche, with the manifestations of verbal and nonverbal components of thinking. An assumption is made about the features of information processing of the verbal and nonverbal components of thinking. The analysis of their connection with the conscious and unconscious areas of the psyche is carried out. The possible procedural and structural aspects of self-organization of thinking, implemented on the basis of verbal and nonverbal thinking, are determined. The assumption is made about the use of the obtained results in training to improve the efficiency of information assimilation.

Published: June 2022

The modern information and digital society is radically changing the conditions of life and the ways of social interaction. Intelligent systems are replacing human potential. The replacement of human resources with intelligent systems is happening rapidly and at the same time imperceptibly. Cognitive abilities of students are natural evolutionary-embedded data. The scientific problem of the research consists in the complexity of the phenomenology of the study of unconscious cognitive processes. The purpose of this study is to analyze cognitive abilities and develop a barcode card as a method of a unified measurement system. The Tape line converter was used in the study, which converts qualitative immeasurable indicators into quantitative ones. The results of the study clearly demonstrate the quantitative characteristics of the range of cognitive abilities available to students. The research contribution consists in several directions: an individual characteristic of each function of cognitive abilities has been developed; in the near digital future, intelligent systems that are able to calculate the amount of functionality of cognitive abilities with the help of a CbS barcode card will hire specialists for work. The value of research work consists in a new way of revealing the inner evolutionary inherent in nature and improved by experience and skills of the range of qualities of cognitive abilities. The practical significance of the results of the work can be implemented as a pilot project in the search system for employees for a certain position.

Authors:   Texas Tech University, Kakar Ashish
Published: June 2022

Social media has had a huge impact on how we live and interact as a society. Yet, research literature is sparse on the psychology of users who participate enthusiastically in the social media. In this exploratory study with 222 student users we apply the theory of fundamental human needs to predict and assess the psychological profile of users who actively engage in social media. Overall the finding of the study support our hypothesis but with a few unexpected findings. Need of relationship, self-esteem and popularity-influence were found to positively impact the behavioral intention, frequency and time users spent on social media. The findings have useful practical implications for product/ project managers in understanding what motivates users to engage in social media and how social media can be designed to further enhance user participation.
Changing Product Perceptions: A Pre-COVID-19 and Post-COVID-19 Survey of Software Products
Authors:   Alabama State University, Kakar Adarsh
Published: June 2022

Traditionally software products have been classified as utilitarian or hedonic based on the value they provide to the users. In this cross-disciplinary study, we introduce another category of software products called social products i.e., those which provide symbolic value to its users. However, we also suggest these three types of software products are ideal types. In reality, most software products are likely hybrid. They provide differing magnitude of all three values: Utilitarian, Hedonic and Social. We use the different levels (high, medium, and low) of these three values to classify products as predominantly Utilitarian, predominantly Hedonic, predominantly Social and five types of Hybrids. This classification of products offers a fresh perspective into how users view different products in terms of the value they provide to them. The insights from the study can be used to assess software product positioning and to develop suitable product development strategies.
The Persistent Digital Divide: The Case Study of a Minority Serving Institution
Authors:   North Carolina A&T State University, Phillips Brandis , Shipps Belinda
Published: June 2022

The COVID-19 pandemic has laid bare the persistent digital divide between those that have access to technology and those that do not. As such, we conducted a case study that consisted of interviews and a survey of students along with interviews of administrators and faculty at a minority serving institution. The institution is used along with resources and appropriations theory as a lens to further understand the digital divide and how technology access and use have manifested during the pandemic. The results suggest that students perceived difficulty with access to and use of information communication technologies (such as hardware and software), which interfered with their engagement with learning. At the institution under investigation, the pre-pandemic lack of access to technological resources was eliminated during the pandemic thanks to additional funding. Nevertheless, the communication problems between the administration and students limited students’ access to the resources available.

Published: June 2022

This study utilizes an explanatory sequential mixed-methods design to examine the impact of COVID-19 on the career trajectories of information technology (I.T.) graduate students and professionals of color. Building on individual differences theory in the initial quantitative phase, data from a national survey of 356 STEM graduate students and professionals of color (Black, Indigenous, and Latino) were analyzed to investigate intersectional differences among I.T. and non-I.T. STEM graduate students and professionals by race/ethnicity, gender, and socio-economic characteristics. Findings suggest differential impacts of COVID-19 on I.T. graduate students and I.T. professionals. Among STEM graduate students, financial strain significantly affected their career plans, whereas among professionals, gender was a significant predictor. Qualitative evidence from I.T. respondents clarified quantitative findings. I.T. graduate students (n=239) were more concerned about research setbacks and career instability, while I.T. professionals (n=117) were concerned with setbacks in professional roles and networks, work/life stability, and increased desires for entrepreneurship.

Published: June 2022

With the declaration of COVID-19 as a pandemic by the World Health Organization and associated public health concerns and emergency measures, the lives of many came to a grinding halt. Whether due to stay-at-home orders and lockdowns, or quarantines, many were required to change their day-to-day way of life overnight. This not only changed the mechanical activities performed daily, such as driving to the office, going out to a restaurant, or attending a party, but this also changed the resultant implications of the utility we received from those activities. Utility theory posits that individuals choose what activities to perform based on some utility function, where the utility satisfies some need. As these activities to meet existing needs were disrupted, we seek to use this as an opportunity to explore how contribution in open-source communities changed, specifically the English Wikipedia. We utilize a natural experiment methodology, centered around the COVID-19 pandemic, and explore contribution patterns before and after the pandemic. Our project will contribute to the understanding of IS during unusual times, specifically in the context of open-source communities that rely on volunteer time and effort.

Proposed below is a mathematical model for reception and processing of spurious (“uncontrolled” radiation) from constantly operating units of the special complex installed onboard a spacecraft. This model makes it possible to implement a new technique for identification of such radiation thus improving the capabilities of the space monitoring. At the same time creation of stand-alone radio systems solely for identification of the spacecrafts based on the proposed mathematic model would require significant expenses therefore it is worthwhile to add new identification hardware to the existing ground-based radio systems used for space flight control. Identifying features in the proposed mathematical model are the parameters of signals of the uncontrolled radiation from constantly operating units installed onboard spacecrafts that “leak” through antenna systems (master generators, heterodyne oscillators in the spacecraft radio receivers). Identification of spacecrafts by uncontrolled radiation from the receiving master generators and heterodyne oscillators involves keeping track of the behavior of oscillation parameters as well as identifying signs that distinguish the oscillations of one generator from another. Since the uncontrolled radiation from heterodyne oscillators is a harmonic oscillation, it features such parameters as amplitude, frequency and initial phase. It is impossible to use the amplitude and initial phase of the signal for identification purposes because the propagation medium strongly affects these parameters. The most informative for identification purposes is the frequency of oscillations, or rather, the behavior of the frequency changes over time. These changes are due to the frequency instability of the onboard master generators. The behavior of the frequency change depends on the characteristics of each onboard generator, which serves as a basis for identification. It should be noted that the identification process can be conditionally divided into two stages: the first stage includes validation of models and processing (evaluation) algorithms while the second stage involves classification of the results of processing (evaluation).

A brief description of the radar CAD software modules responsible for this functionality is given. The module of engineering calculations and simulations allows you to set the scenario of the interference-target situation and conduct a complete, close to reality, simulation of the behavior of the radar in combat conditions. The visual functional editor provides the ability to create a radar simulation model in the form of a graph of streaming calculations from interconnected parameterizable blocks. The library of parameterizable modeling blocks contains modeling blocks designed for calculations and modeling of structural and functional parts of developed radar stations, complexes, systems. Simulation model of an active single-position pulse-Doppler sector-observation radar with electronic beam scanning was created. The following algorithms are implemented in the model: the sum-difference monopulse direction finding algorithm, the MUSIC superresolution direction finding algorithm, and the projection adaptive spatial filtering algorithm. A simulation experiment was carried out with a radar model in three scenarios of an interference-target environment, which differ in the presence of interfering signals. Analysis of the results of the simulation experiment shows that the operation of the algorithms corresponds to the theoretical prediction. The abilities of radar CAD presented in this article can be used by specialists in radar and signal processing.

On the basis of nonlinear systems with dynamic chaos, discrete chaotic signals with high information capacity have been developed and studied. The influence of the main parameters of a generating chaotic algorithm with delay on the statistical, correlation, structural and fractal characteristics of non-periodic pseudo-random integer and binary sequences generated by the algorithm is analyzed by numerical methods. It is shown that non-periodic pseudo-random sequences (PRS) generated by a chaotic algorithm with delay, for all values of the main parameters, have good statistical, correlation, structural and fractal characteristics, close to random sequences of independent trials. It is shown that these characteristics are provided on a long PRS cycle in a multidimensional phase space for all the main parameters of the chaotic algorithm and an arbitrary choice of initial conditions. Such binary PRSs can be quite effectively used in telecommunication systems using streaming coding of large blocks of information messages from the point of view of secrecy, noise immunity and cryptographic stability of the communication channel.

Published: June 2022

The aim of the work is to consider the problems of numerical simulation of seismic safety of a console and a ten-storey building with a base in the form of an elastic half-plane under non-stationary wave influences. Modeling of tasks of the transition period is an actual fundamental and applied scientific task. Methodology. To solve a two-dimensional plane dynamic problem of elasticity theory with initial and boundary conditions, the finite element method in displacements is used. Based on the finite element method in displacements, an algorithm and a set of programs have been developed for solving linear planar two-dimensional problems that allow solving problems with non-stationary wave effects on complex systems. The algorithmic language Fortran-90 was used in the development of the software package. Результаты. Results. The problem of the effect of a plane longitudinal wave in an elastic half-plane in the form of four trapezoids and in the form of two half-periods of a sinusoid is considered to assess the physical reliability and mathematical accuracy. A system of equations consisting of 8016008 unknowns is solved. The problem of the effect of a plane longitudinal elastic wave in the form of a Heaviside function on a console with a base (the ratio of width to height is one to ten) is considered. A system of equations consisting of 16016084 unknowns is solved. The problem of the effect of a plane longitudinal elastic wave in the form of a Heaviside function on a ten-storey building with a base in the form of a half-plane is considered. A system of equations consisting of 16202276 unknowns is solved. Contour stresses and components of the stress tensor are obtained in the characteristic areas of the problem under study. Based on the conducted research, the following conclusions can be drawn. Elastic contour stress on the sides of the console and a ten-story building are almost a mirror image of each other, that is, antisymmetric. The console and supporting structures of the building work like a beam during seismic action, that is, if there are tensile stresses on one side, then compressive stresses on the other. Bending waves mainly prevail on the contours of the console and supporting structures of the building under seismic influence.

Results: Twenty-one studies were included that addressed the presence of symptoms of PTSD, anxiety, depression, fatigue in sleep disorders in COVID19 survivors. Conclusion: With this literature review, it can be concluded that PTSD, anxiety, depression, fatigue and sleep disturbances are highly prevalent symptoms in COVID-19 survivors, being persistent for up to one-year post-infection.
Las «Obras poéticas» de Ana de San Jerónimo: textos y contextos de la representación autorial
Authors: Osuna Rodríguez Inmaculada
Published: June 2022

En 1773 se publicaron póstumas en Córdoba las Obras poéticas de Ana de San Jerónimo, franciscana descalza del convento del Santo Ángel de Granada. La colección poética está precedida por una dedicatoria del anónimo compilador y editor dirigida a la abadesa y por una semblanza biográfica de la autora. Además, el primer poema presenta dos textos preliminares de esta, pensados para una hipotética difusión impresa. Paratextos, poemas y otras fuentes, textuales o documentales, permiten profundizar en la dual imagen autorial ofrecida al lector en el libro. La imagen de alta estima proveniente de la perspectiva externa que expresan los paratextos no autoriales y traslucen unos pocos versos aislados de la autora contrasta con la humilitas literaria y moral que pauta su autorrepresentación, sin que eso obste para su autoafirmación en la escritura poética y en su legitimación.
Orientalismo y perspectiva de género en el teatro ilustrado español: la tragedia «Ali-Bek» (1801) de María Rosa de Gálvez
Authors: Establier Pérez Helena
Published: June 2022

Entre las escasas tragedias originales españolas que se adscriben a la tendencia orientalista en el cambio de siglo, Ali-Bek, publicada y representada en 1801, constituye, por su autoría femenina y su perspectiva de género, un caso singular de aprovechamiento del espacio dramático para insertarse exitosamente en una parcela del campo literario de la cual las mujeres habían estado ausentes hasta entonces. En este trabajo, estudiaremos la obra de María Rosa de Gálvez en el marco del orientalismo dieciochesco y analizaremos las fuentes, las estrategias teatrales y el sustrato ideológico que le permitieron servirse del exotismo dramático para hacer de su primera tragedia un vehículo de jugosos mensajes de talante ilustrado y protofeminista.

Authors: Ozolinya Lyudmila A. , Belousova Alina O. , Useinova Sofiya E.
Published: June 2022

Currently, uterine fibroids are one of the most common gynecological diseases, with surgical treatments provided in many cases, but hormone therapy is widely used. Gynecologists must consider all aspects of the patients condition during treatment, including the blood coagulation system status. Features of hemostasis affect the disease development, features and outcomes of the operation, and the postoperative period course, as well as the possibility of carrying out the necessary drug therapy and its results. This literature review reflects the results of research by domestic and foreign authors regarding the hemostasis system status in patients with uterine fibroids, including the effect of hormonal, antioxidant, and disaggregate therapy. The studies conducted allowed the authors to predict the possibility of bleeding and thromboembolic complications in patients, as well as the growth of uterine fibroids, to timely correct hemostasis and improve the treatment results in patients with this pathology.

Optimización de los protocolos de congelación de eyaculados de oso pardo (Ursus arctos)
Authors: Álvarez Rodríguez Manuel
Published: June 2022

La situación crítica del oso pardo (Ursus arctos) en España plantea la necesidad de aplicar diferentes estrategias de conservación, dentro de las cuales tiene especial relevancia la creación de un banco de recursos genéticos. La eficacia de esta herramienta depende, entre otros factores, de la adaptación específica de los protocolos de congelación espermática ya existentes y que permitan el almacenamiento eficaz de los espermatozoides del oso pardo en un banco de germoplasma. Este trabajo nos permite concluir la utilidad de la selección entre ciclos con el fin de mejorar la calidad de los espermatozoides sometidos a recongelación

Explica su trayectoria profesional que empieza con la pesca eléctrica del Lucio. En diciembre de 1992 se aprobó en el parlamento regional la ley 6/92 de protección de los ecosistemas acuáticos y de regulación de la pesca en Castilla y León, que por primera vez contemplaba la necesidad de basar la gestión de la pesca en estudios previos que cuantificasen el recurso y asegurasen su persistencia. La administración regional decidió implantar los denominados “estudios hidrobiológicos de cuenca” como herramienta base de la planificación de la gestión de poblaciones de peces, y yo decidí dar un salto sin red y dedicarme a la realización de los mismos en ese pantanoso mundo de la “consultoría ambiental” Icthios
