ЗООГЕОГРАФІЧНА ХАРАКТЕРИСТИКА НАПІВТВЕРДОКРИЛИХ (HEMIPTERA: HETEROPTERA) УРБОЦЕНОЗІВ МІСТА ХАРКІВ
Authors: Fedyay I. O. , Markina T. Yu.
Published: January 2022

Наведено зоогеографічну характеристику напівтвердокрилих урбоценозів м. Харків (Україна), що демонструє досить велику роздрібненість типів ареалів клопів на території міста. Це може бути пов’язано з мозаїчністю умов існування комах в різних біотопах, що сприяє підвищенню різноманіття видів клопів з різних зоогеографічних груп (підгруп). Загалом виділено 20 типів видових ареалів, об’єднаних в 12 секторних груп. Найбільшими (як за кількістю видів, так і за чисельністю) виявились представники транспалеарктичної (64 види), західно-палеарктичної (62), європейської (20) та голарктичної (18) груп ареалів. Інші групи включали від одного до трьох видів. Чотири види клопів мають позапалеарктичний тип поширення з космополітним, неарктичним (по одному виду) та субкосмополітним (два види) ареалами.

Influence of potential nanopollutant fullerene C60 on physiological and biochemical responses in mammals
Authors: Nedzvetsky V. S. , Gasso V. Y. , Yermolenko S. V. , Hasso I. A.
Published: January 2022

The progressive development of technologies in the manufacture and application of nanomaterials in almost all spheres of human life causes penetration in an organism and accumulation of nanoparticles in its cells. Determinations of the risk of using nanomaterials and mechanisms of their cytotoxicity are extremely relevant current problems that should be studied. Fullerene C60 is the most widespread nanomaterial proposed to use inhibition of tumour growth, microbial infections, and purposeful drug delivery. However, there are contradictory data on cytotoxic and/or cytoprotective effects of this fullerene. In the present paper, the action of fullerene C60 on glucose metabolism, the composition of the intestinal microbiota, and an acid-reducing balance were studied in rats. It is shown that fullerene C60 dissolved in olive oil (2 mg/kg/day) induces insulin resistance, activates the peroxidation of lipids in the brain of animals, but not in the liver, under conditions of chronic influence. In addition, fullerene C60 induced changes in the composition of the intestinal microbiota in rats. Determined disorders may be a cause of insulin production, as an adaptive response to the needs of metabolic energy under local oxidative stress in the nerve tissue. At the same time, the growth of insulin resistance can be induced by nonspecific molecular damage in biomembranes and macromolecules, including insulin receptors. In this regard, the explanation of the molecular mechanisms of insulin resistance induced by fullerene C60 together with the effect of fullerene dose will be of particular interest in further studies.
Influence of pyrethroid and neonicotinoid insecticides on lizards (Reptilia, Squamata) (a review)
Authors: Yermolenko S. V. , Gasso V. Y. , Spirina V. A. , Huslystyi A. O.
Published: January 2022

Pyrethroid and neonicotinoid pesticides are synthetic substances that are distributed in different economic activity spheres and until recent times were considered one of the safe types of insecticides. It is known that the use of pyrethroid and neonicotinoid insecticides have certain environmental risks for animal populations. Reptiles manifest a significant sensitivity to this family of insecticides. Lizards (Lacertilia) is a numerous group of animals, a large number of species of which is associated with biotopes located in the landscapes influenced by pesticides. Features of toxic effects of pyrethroid and neonicotinoid insecticides are investigated on a small number of Lacertilia species and mainly on small lizards. An analysis of previous studies allowed identifying certain features of the toxic effect of pyrethroids and neonicotinoids on the lizards. Affecting this group of insecticides in lizards may increase mortality and neurological deviations, whose symptoms may reduce over time. Laboratory studies indicate that these substances can lead to increased lizard lethality and to hormonal, biochemical, and neuralgic deviations. The conducted studies indicate that these insecticides have an antiandrogenic effect that may decrease the reproductive success of lizards. The metabolism of insecticides in the lizard organism causes the formation of toxic metabolites, which may be accompanied by a greater poisoning of the lizard body than detoxification. Enantiomers of the investigated insecticides, exhibit a different degree of toxicity. A number of parameters of toxic effects are proposed as biomarkers of intoxication with pyrethroid and neonicotinoid insecticides. Lizards can be used for bioindication of synthetic insecticides, but the research activities on this issue began to grow in recent decades.

This study presents the results of some options to restore pastures with low productivity in the arid steppes of the Kostanay region of northern Kazakhstan, describing the effects associated with grass-legume mixtures. The effects of grass-legume mixtures, contribution to the preservation and maintenance of pasture forage crops, and the productivity of pastures were discussed. Mixtures of grasses and legumes were selected that are promising crops for arid regions.The plant density and its condition were determined based on test plots of adjacent rows of 0.5 m each, followed by counting. The plant height was determined before the yield of green mass by measuring 25 plants of each species. The yield of green mass in the maturity phase of the grass was determined by mowing and weighing the green mass in the plots, followed by the analysis of the species composition in the grass mixture and drying until air dry. The density of plants, the height of the plants, and the safety of the forage plants according to the sowing method were the data collected. In addition, the effect of grass mixtures on the productivity of forage crops to improve pastures was compared. According to these results, the highest productivity under experimental conditions was found in the wheat grassalfalfa-bromegrass variant. This information can contribute to the improvement of the state of the pastures since it is complete and inexpensive food for farm animals.

Published: January 2022

Theobroma cacao is the main raw material to produce chocolate, as well as for use in the food, cosmetic, and pharmaceutical industries. However, Moniliophthora roreri is one of the most destructive fungal diseases and the main limiting of cacao production worldwide. Thus, this work aimed to assess the inhibitory effect of extracts of Zingiber officinale (T1) and Aloe vera (T2), and Trichoderma harzianum + Bacillus subtillis. (T3) on Moniliophthora roreri infection in Theobroma cacao; in addition, a control (T4) was also evaluated. Each treatment was applied to six plants of cacao. Incidence of monilia infection and fruit weight were monitored every 15 days (in total four periods) after the application of the treatment by spray. Significant differences (P<0.05) were found among treatments for incidence. It was observed that spraying entire cacao trees after two times (approximately 30 days) showed a reduction of monilia infection. After all periods, T1, T2, and T3 showed an incidence of monilia infection by 20.5, 17.7, and 14.9% respectively, compared to cultural control of 41.1%. This reduction of moniliasis infection translates into an increase in fruit weight average for T3 (8.4 kg), T2 (7.3 kg), and T1 (6.9 kg). In contrast, in the control (T3), the fruit weight average decreased by 5.3 kg. Biological control showed efficient management of pathogens as M. roreri. It is recommended to use such antifungal (Aloe vera) spray over at least 120 days which would decrease infection incidence even more.

Published: January 2022

Due to the wide applicability of separation techniques that rely on the property of differential migration in pharmaceutical formulations analysis, different analytical strategies have been proposed to resolve mixtures of multi-components pharmaceuticals. Three separation methods were developed and validated for the simultaneous determination of Paracetamol (PAR), Pseudoephedrine HCl (PSE) and Chlorpheniramine maleate (CHP). The first method is a thin-layer chromatographic (TLC) separation, followed by densitometric measurement. The separation was carried out on aluminium sheet of silica gel 60 F254 using ethanol:chloroform:ammonia (1:7:0.4, by volume) as the mobile phase. Determination of PAR, PSE and CHP was successfully applied over the concentration ranges of 3–25 µg/band, 0.5–10 µg/band and 0.1–6 µg/band, respectively. The second method is HPLC separation that was achieved on C18 column using the mobile phase acetonitrile:phosphate buffer pH 5 (10:90, v/v) at a flow rate 1 mL min−1. PAR, PSE and CHP were determined by HPLC in concentration ranges of 5–400 μg mL−1, 2–40 μg mL−1 and 0.5–16 μg mL−1, respectively. The third method is a capillary electrophoresis (CE) separation. The electrophoretic separation was achieved using 20 mM phosphate buffer (pH 6.5) at 20 kV. The linearity was reached over concentration ranges of 30–250 μg mL−1, 5–50 μg mL−1 and 0.8–20 μg mL−1 for PAR, PSE and CHP, respectively. The developed methods were validated with respect to linearity, precision, accuracy and system suitability. The proposed methods were successfully applied for bulk powder and dosage form analysis with RSD of precision <2%. Moreover, statistical comparison with the official methods confirms the methods' validity.

Published: January 2022

A systematic DoE and Analytical Quality by Design (AQbD) approach was utilized for the development and validation of a novel stability indicating high-performance thin–layer chromatographic (HPTLC) method for Rivaroxaban (RBN) estimation in bulk and marketed formulation. A D-optimal design was used to screen the effect of solvents, volume of solvents, time from spotting to development and time for development to scanning. ANOVA results and Pareto chart revealed that toluene, methanol, water and saturation time had an impact on retention time. The critical method and material attributes were further screened by Box-Behnken design (BBD) to achieve optimal chromatographic condition. A stress degradation study was carried out and structure of major alkaline degradant was elaborated. According to the design space, a control strategy was used with toluene: methanol: water (6:2:2) and the saturation time was 15 min. A retention factor (RF) of 0.59 ± 0.05 was achieved for RBN using chromatographic plate precoated with silica gel at detection wavelength 282 nm with optimized conditions. The linear calibration curve was achieved in the concentration range of 200–1,200 ng/band with r2 > 0.998 suggesting good coordination between analyte concentration and peak areas. The quadratic model was demonstrated as the best fit model and no interaction was noted between CMAs. The optimized HPTLC method was validated critically as stated in International Conference on Harmonization (ICH) Q2 (R1) guideline and implemented successfully for stress degradation study of RBN. The developed HPTLC method obtained through AQbD application was potentially able to resolve all degradants of RBN achieved through forced degradation study. The obtained results demonstrate that a scientific AQbD approach implementation in HPTLC method development and stress degradation study drastically minimizes the number of trials in experiments, ultimately time and cost of analysis could be minimized.
Alternative news on social media in Norway
Authors: Wold Thomas
Published: January 2022

Alternative news media in Norway have become visible in public debates. Partly because of news sharing on social media. Social media has become an arena for news, information, and public debate, and has also become a place to fight for the news agenda. The present study examines news sharing in social media in Norway and how right-wing alternative news outlets use social media to impact the news agenda. These are small organizations with only a handful of employees, but they have very proactive readers and feature a considerable amount of user-generated content. They are critical of immigration, particularly from Muslim countries, and of the political elite. They mimic traditional media in the way they organize and label their content, but their reporting is more subjective. The present study uses quantitative content analysis to reveal which topics are the most shared on social media, and from which news type of news organizations they come. It also looks at how news sharing differed in the days following a series of terrorist attacks and how the pattern changed during the course of a normal day. This leads to a discussion on participatory journalism and how news sharing can be seen as a part of the public debate.
Analysis of COVID-19 news coverage by Televisión Española (TVE1)
Authors: Rosique-Cedillo Gloria , Crisóstomo-Flores Paz-Andrea
Published: January 2022

This article analyzes the news coverage of the COVID-19 health crisis by Televisión Española (TVE1), to determine if this media reported the news with rigor and in accordance with journalism professional codes and best practice guidelines. For this purpose, content analysis was conducted on the universe of news stories (n=1,449) in the TVE1 daily newscast, starting with the first outbreak of the pandemic on the Iberian Peninsula on February 26, 2020, until the end of the first state of emergency on June 21, 2020. Our categories of analysis were: information sources, news frames, predominant topics, resources used for dramatic effects, and breaches of journalism ethics in reporting news. In general, TVE1 did not engage in sensationalized or dramatized news coverage, but instead attempted to transmit a message that was educational and instructional. Its policy was to provide information on measures adopted by authorities to help prevent the spread of the pandemic. Nevertheless, TVE’s benevolent attitude towards the government and its policies can be observed in its news reporting, revealing a lack of impartiality and editorial independence by this media. Despite the importance of specialized and expert information in times of a pandemic, eyewitness sources were those most used in reporting news, even in economic news framing. Furthermore, these latter sources were employed instead of expert ones, which were in fact the least used, and whose presence progressively declined during the analyzed period.
Derivational networks of Onomatopoeia
Authors:   Pavol Jozef Šafarik University of Košice, Slovakia, Andrej Ľubomír
Published: January 2022

This paper presents research on the word-formation properties of onomatopoeia, or words imitating natural sounds. The research is conducted with the model of derivational networks, a relatively new approach to the theory of derivational paradigms, introduced for the first time in the book Derivational Networks Across Languages. The main aim of the analysis is to discover whether onomatopoeia can become a productive word-formation bases, and if so, how productive, and what kind of derivatives can be created. The research also compares English and Slovak onomatopoeia. The paper is divided into three main sections: part 2 introduces the concept of derivational networks and discusses its evolution through the works of Czech and Slovak linguists. Part 3 discusses the notion of onomatopoeia, what it is, and how it is understood and defined for the purpose of this research. Finally, part 4 presents the research itself, including the methodology, results, and discussion.

In the subsequent research part, the reported data formed the basis for conclusions supported by two-year observation and interviews of 4 Spanish-English bilinguals. The case studies allowed to gather information regarding their linguistic and cultural behaviour and how they identify themselves both linguistically and culturally. Each case study is discussed and conclusions on parallel points along with dissimilarities between accounts of the linguistic and cultural reality experienced in both languages are outlined.
People in aviation – a linguists’ insight into history
Authors:   University of Rzeszow, Poland, Kopecka Beata
Published: January 2022

History can be studied from a number of angles and on the basis of a variety of sources. Researchers interested in the history of aviation typically focus on the development of subsequent types of flying machines. This study relates to the history of aviation, but, due to its linguistic bias it concentrates on the semantic field . The structure of this field is analysed on the basis of a collection of nouns that form the relating lexical fields. In detail the study is aimed to cast some light on the history of modern aviation, i.e. aviation that started with the 1903 flight made by the Wright Brothers in an engine-driven machine, and has been continued up to now. Importantly, in 1911, soon after the first flight took place, the first dictionary of aviation was published. This specialized dictionary served as an inspiration for an attempt to draw a linguistic picture of the discipline at the beginning of the 20th century, and later to contrast it with a linguistic picture of the discipline as emerging from modern specialized dictionaries of aviation one century later. Additionally, the analysis of particular nouns, including the study of their morphological structure and semantics leads to some interesting observations relating to the history of modern aviation.

Published: January 2022

We study the class of order weakly compact operators on locally solid Riesz spaces and the introduced class of generalized $b$-weakly compact operators on locally convex-solid Riesz spaces. We prove as a consequence that some well-known results on $b$-weakly compact operators on a Banach lattice extend in an improved version to generalized $b$-weakly compact operators on a Fréchet lattice.
Subdirectly irreducible semilattices with endomorphism
Authors: FANG Jie
Published: January 2022

In this paper we initiate an investigation into the class of meet semilattices endowed with an endomorphism. A consideration of the subdirectly irreducible algebras leads to a description of a subclass of those algebras (S;∧,k)(S;∧,k) in which (S;∧)(S;∧) is a meet semilattice and kk is an endomorphism on SS characterised by the property k⩾idSk⩾idS. We particularly show that such an algebra is subdirectly irreducible if and only if it is a chain with one of the following forms ⋯<aj<aj−1<⋯<a0⋯<aj<aj−1<⋯<a0;0⋯<aj<aj−1<⋯<a00⋯<aj<aj−1<⋯<a0 in which k(aj)=aj−1k(aj)=aj−1 for j⩾1j⩾1, k(0)=0k(0)=0 and k(a0)=a0k(a0)=a0.

Authors: Southall Emma , Lukashuk Liliana
Published: January 2022

The deployment of hydrogen as an infrastructure fuel and an energy vector across a range of industries is expected to aid with meeting decarbonisation goals and achieving net zero emissions. For the transition towards a low carbon hydrogen economy, not only the production of hydrogen needs to be addressed, but also its transportation and storage. Liquid organic hydrogen carriers (LOHCs) are an attractive solution for the storage and transportation of hydrogen to allow a reliable and on-demand hydrogen supply, enabling industrial decarbonisation. This work describes the potential deployment and integration of LOHCs within different industries. These include: the transportation sector; steel and cement industries; the use of stored hydrogen to produce fuels and chemicals from flue gases and a system integration of fuel cells and LOHCs for energy storage.
Analysis of Liquid Organic Hydrogen Carrier Systems
Authors: Southall Emma , Lukashuk Liliana
Published: January 2022

Liquid organic hydrogen carriers (LOHCs) provide attractive opportunities for hydrogen storage and transportation. In this study, a detailed examination of the most prominent LOHCs is performed, with a focus on their properties and scope for successful process implementation, as well as catalytic materials used for the hydrogenation and dehydrogenation steps. Different properties of each potential LOHC offer significant flexibility within the technology, allowing bespoke hydrogen storage and transportation solutions to be provided. Among different LOHC systems, dibenzyltoluene/perhydro-dibenzyltoluene has been identified as one of the most promising candidates for future deployment in commercial LOHC-based hydrogen storage and transport settings, based on its physical and toxicological properties, process conditions requirements, availability and its moderate cost. Platinum group metal (pgm)-based catalysts have been proven to catalyse both the hydrogenation and dehydrogenation steps for various LOHC systems, though base metal catalysts might have a potential for the technology.
Day‐ahead forecasting of losses in the distribution network
Authors: Dalal Nisha , Mølnå Martin , Herrem Mette , Røen Magne , Gundersen Odd Erik
Published: January 2022

Utility companies in the Nordics have to nominate how much electricity is expected to be lost in their power grid the next day. We present a commercially deployed machine learning system that automates this day‐ahead nomination of the expected grid loss. It meets several practical constraints and issues related to, among other things, delayed, missing and incorrect data and a small data set. The system incorporates a total of 24 different models that performs forecasts for three sub‐grids. Each day one model is selected for making the hourly day‐ahead forecasts for each sub‐grid. The deployed system reduced the mean average percentage error (MAPE) with 40% from 12.17 to 7.26 per hour from mid‐July to mid‐October, 2019. It is robust, flexible and reduces manual work. Recently, the system was deployed to forecast and nominate grid losses for two new grids belonging to a new customer. As the presented system is modular and adaptive, the integration was quick and needed minimal work. We have shared the grid loss data‐set on Kaggle.
Considerations on creating conversational agents for multiple environments and users
Authors: Cebrián Javier , Martínez Ramón , Rodríguez Natalia , D'Haro Luis Fernando
Published: January 2022

Advances in artificial intelligence algorithms and expansion of straightforward cloud‐based platforms have enabled the adoption of conversational assistants by both, medium and large companies, to facilitate interaction between clients and employees. The interactions are possible through the use of ubiquitous devices (e.g., Amazon Echo, Apple HomePod, Google Nest), virtual assistants (e.g., Apple Siri, Google Assistant, Samsung Bixby, or Microsoft Cortana), chat windows on the corporate website, or social network applications (e.g. Facebook Messenger, Telegram, Slack, WeChat).

Creating a useful, personalized conversational agent that is also robust and popular is nonetheless challenging work. It requires picking the right algorithm, framework, and/or communication channel, but perhaps more importantly, consideration of the specific task, user needs, environment, available training data, budget, and a thoughtful design.

In this paper, we will consider the elements necessary to create a conversational agent for different types of users, environments, and tasks. The elements will account for the limited amount of data available for specific tasks within a company and for non‐English languages. We are confident that we can provide a useful resource for the new practitioner developing an agent. We can point out novice problems/traps to avoid, create consciousness that the development of the technology is achievable despite comprehensive and significant challenges, and raise awareness about different ethical issues that may be associated with this technology. We have compiled our experience with deploying conversational systems for daily use in multicultural, multilingual, and intergenerational settings. Additionally, we will give insight on how to scale the proposed solutions.
Computation of local permeability in gap-graded granular soils
Authors: Annapareddy V. S. R. , Sufian A. , Bore T. , Bajodek M. , Scheuermann A.
Published: January 2022

This paper proposes semi-analytical methods to obtain the local permeability for granular soils based on indirect measurements of the local porosity profile in a large coaxial cell permeameter using spatial time-domain reflectometry. The porosity profile is used to obtain the local permeability using the modified Kozeny–Carman and Katz–Thompson equations, which incorporated an effective particle diameter that accounted for particle migration within the permeameter. The profiles of the local permeability obtained from the proposed methods are compared with experimentally obtained permeability distributions using pressure measurements and flow rate. The permeabilities obtained with the proposed methods are comparable with the experimentally obtained permeabilities and are within one order of magnitude deviation, which is an acceptable range for practical applications.

In this study, ceramic coatings were prepared on the surface of TC4 titanium (Ti) alloy by micro-arc oxidation (MAO). The morphology, element distribution and phase composition of MAO coatings were analyzed by scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction and other analytical methods. The effect of hexagonal boron nitride (h-BN) doping on the wear resistance and corrosion resistance of the MAO layer was studied. The results showed that the coating was mainly composed of rutile titanium dioxide (TiO2), anatase titanium dioxide and a small amount of h-BN. Furthermore, the composite coating containing h-BN was less porous than the particle-free coating. The test results showed that h-BN doping slightly affected the hardness of the MAO coating, and it was helpful in improving the thickness, corrosion resistance and wear resistance of the coatings. When the amount of h-BN was 3 g/l, the corrosion current density of the coating was the smallest. When the addition of h-BN was 1.5 g/l, the friction coefficient of the coating was the smallest. The wear mechanism was adhesive wear, accompanied by slight abrasive wear.

The aim of this paper is to present an outline of the history of physical culture in the Stanisławowski province (an area that is currently within the borders of Ukraine) in the period 1920-1939 in the times of the Second Polish Republic. In the inter-war period the development of physical culture took place in the Stanisławowski province. In the period of the 1920s and 1930s there was a development of sports infrastructure. Social and sports associations were established, while also sports clubs, as well as the fact that sports organizations were reactivated that had operated in the period prior to the outbreak of the First World War among the Polish, Ukrainian and Jewish communities. Organizational structures of sporting movements were established, among others, Stanisławowski District Football Association, as well as structures at a sub-district level. The development of sporting competition took place. The most popular sporting discipline was football; while also gymnastics, horse riding, cycling, athletics, shooting, skiing, table tennis.

Construction companies face barriers and challenges in adopting BIM, as there are no guidelines or best practices they could study and use in their activities. One of the most difficult and time-consu­ming tasks in designing construction projects is calculating the volume of earthworks, which sometimes has to be done in difficult climatic conditions. The article presents a study of using BIM technology and the development of a script in the visual programming environment «Dynamo», which will simplify this labour intensive process without losing its quality and saving time for other design tasks. The deve­loped script can be used when calculating earthworks and studying their fill diagram in order to cut costs of performing initial construction works by designing marks on the Earth’s surface. It can be used in road building when plotting the most economically feasible route in terms of construction costs. The use of the developed script will significantly reduce the time of performing a big amount of same type repetitive operations when developing representative units or creating complex parametric geometry.
Adapting Income Taxation to the Labor Market Changes
Authors: Kireenko Anna , Sodnomova Svetlana
Published: January 2022

The article is concerned with the analysis of the labor market changes, requiring the personal income tax reform. Methods of comparative and statistical analysis are applied. Rating and analytical agencies data, statistics from the OECD, Eurofond and Eurostat used as the empirical base of the study. Three labor market trends requiring appropriate changes in taxation were identified. The first trend is the change in the demand for work skills, which requires a more flexible approach to educational tax deductions and tax incentives for training in high-demand digital professions. The second trend is digital platforms and the gig economy that enhance income differentiation, which inevitably raises the question of progressive income taxation. The third trend is an increase in non-standard employment. The article analyzes such forms of non-standard employment as work on the basis of vouchers, platform work, joint employment, casual labour which are associated with the ambiguous status of employment and require changes in tax policy to regulate them.
A Comparative Analysis of the Social Well-Being of a Person in the Conditions of Freedom and Isolation
Authors: Telegina Elena , Nesterenko Irina
Published: January 2022

The authors examine a complex of methods for identifying the emotional-evaluative attitude of individuals to the social reality and their place in it in the conditions of freedom and isolation. Using the research results and the analysis of practical experience, they describe psychological-pedagogical means and methods that improve the reserve resources of the human body, which leads to positive changes in forming a favorable social well-being and correction of inmates in the conditions of isolation. Special attention is paid to the interactions of employees of the departments of social educational work and psychological labs with inmates in correctional institutions. The authors single out the following methods leading to favorable results in the work of the abovementioned departments: individual and group discussions, doll therapy, use of metaphor (association) cards, psychocorrection, Rokic’s methodology, constitutive method in the form of testing for suicidal tendencies. An important component in the work with the suspects, the accused, and the convicted persons is changing their moral orientations, development of a law-abiding mindset and orientation towards correction (rehabilitation). Criminals can be broken into three groups. The first group is comprised of those who can be successfully rehabilitated, it includes persons with views and convictions which agree with the norms of social community who committed crimes though negligence. The second group includes those who can be rehabilitated, these are individuals with essentially unstable views and convictions. The third group is made up of inmates whose rehabilitation is hardly possible. In this case, the main task of the social education worker consists in using the positive qualities of the convict’s personality to provoke a conflict between the positive and the negative, and the task of the psychologists is to provide psychological support for the person.
Criminological Aspects of Sport Policy
Authors: Kleymenov Mikhail , Kleymenov Ivan
Published: January 2022

Sport policy is a purposeful activity of various subjects connected with organizing and holding sports competitions. Such activity may be state-organized, administrative, financial, commercial, engineering and construction-related, military, security, professional, corporate, training, entertainment, relatively mass-scale, agent, referee, qualifying, and others. It should be taken into account that, besides officially recognized sports, there are also illegal competitions. Criminological aspects, connected with the possibility of crime, can be found everywhere. All of these leads to the necessity of establishing and developing sport criminology as a component of sport policy. Criminological aspects of sport policy are especially evident in the market conditions. Their analysis is necessary for the optimization of preventive work in the most important areas. The authors single out three such areas: criminal law prevention of crime in sports, enforcement of prevention policy for criminal and criminogenic sports, and counteracting sport extremism. The effectiveness of work in the first area is close to zero because special «sport» criminal law norms are not and will not be enforced. The analysis of the second area leads the authors to the conclusion that it is necessary to intensify the counteraction to criminal sports, primarily, dog fighting and street racing. As for the criminogenic sports, they can be conditionally broken into two categories: those promoting violence and cruelty, and those equipping athletes with the skills interesting for the criminal community (organized criminal groups). The first category includes MMA-type female fights. This disgusting spectacle, broadcast on TV, is absolutely contrary both to the female nature and to the traditional values of peoples of Russia. Such fights should be prohibited in the Russian Federation. The third area requires monitoring to prevent fans’ movements from turning into extremist organizations. The promotion of patriotic feelings among fans should be recognized as a strategic direction in the prevention of sport extremism.

Published: January 2022

Este artículo presenta una experiencia educativa de docencia universitaria a través de la cultura visual, la música, la ciencia, la tecnología y las matemáticas en el plan de formación de sesenta futuros diseñadores digitales. El objetivo de este estudio de caso es mostrar el aprendizaje de contenidos curriculares —como el concepto matemático de simetría cuatro π— a través de la alfabetidad visual, las manifestaciones artísticas y, en concreto, musicales como el Canon nº 5 de Johann Sebastian Bach de las Variaciones de Goldberg - BWV 1087. Para ello, se han utilizado marcos conceptuales basados en la pedagogía crítica, la transversalidad, la teoría del andamiaje, la gamificación y el conflicto cognitivo. La investigación fue analizada a partir de la triangulación entre los cuestionarios del alumnado, sus producciones artísticas y sus diarios de investigación, y fueron analizados a través del software ATLAS.ti (versión 7). Los resultados señalan el uso de la alfabetidad visual como generador de situaciones de aprendizaje creativas y disruptivas, posibilitando una mejora formativa en los estudiantes. Se concluye que este enfoque metodológico puede crear puentes entre disciplinas, capacitando a los estudiantes a abordar un pensamiento divergente e inclusivo en sus prácticas profesionales y en sus cotidianidades.

Introduction. COVID-19 affects the hematologic system. We evaluate the impact of hematologic involvement of different blood cell line parameters of white blood cells including absolute neutrophil count (ANC), hemoglobin, and platelets in COVID-19 patients and their association with hospital mortality and length of stay (LOS). 
Methods. This is a retrospective study of 475 patients with confirmed positive COVID-19 infection and hematologic abnormalities in the metropolitan New York City area.
Results. Increased (ANC) (OR:1.20; 95% CI:1.02-1.42, p<0.05) increased days to hematologic involvement (OR:4.44, 95% CI:1.42-13.90; p<0.05), and persistence of hematologic involvement at discharge (OR:2.87, 95% CI:1.20, 6.90, p<0.05) were associated with higher mortality. Higher hemoglobin at admission (OR:0.77, 95% CI:0.60-0.98, p<0.001) and platelets peak (OR:0.995, 95% CI 95%:0.992-0.997, p<0.001) were associated with decreased mortality. Patients with higher white blood cell peak (B=0.46, SE=0.07, p<0.001) and higher hemoglobin at admission (B=0.05, SE=0.01, p<0.001) were associated with higher LOS. Those with higher hemoglobin nadir (B=-0.06, SE=0.01, p<0.001), higher platelets nadir (B=-0.001, SE=<0.001, p<0.001), and hematologic involvement at discharge/death (B=-0.06, SE=0.03, p<0.05) were associated with lower LOS.
Conclusions. These findings can be used by clinicians to better risk-stratify patients with hematologic involvement in COVID-19 and tailor therapies to potentially improve patient outcomes.

Introduction. Poor mental health is associated with worse outcomes for chronic diseases. It is unclear whether mental illness predisposes to difficulties with healthcare access.
Methods. Using a combined dataset of the 2016-2019 behavioral risk factor surveillance system, we included individuals who reported a chronic cardiovascular condition. Weighted multivariable logistic regression analyses were used to explore the association between domains of mental health and measures of healthcare access including delaying medical care, > 1 year since last routine checkup, lack of a primary care physician (PCP), and cost-related medication nonadherence (CRMNA).
Results. Among 1,747, 397 participants, 27% had a chronic cardiovascular condition, 12% had clinical depression, and 12% had poor mental health. Those with poor mental health (OR 3.20 [3.08 – 3.33]) and clinical depression (OR 2.43 [2.35 – 2.52]) were more likely to report delays in medical care.  Those with greater stress frequency (OR 8.47 [6.84 -10.49] stressed all of the time), lower levels of emotional support received (OR 3.07 [2.21 – 4.26] rarely get needed emotional support), and greater life dissatisfaction (6.66 [4.14 – 10.70] very dissatisfied) reported greater delays in medical care.
Conclusions. Individuals with poor mental health have greater difficulty accessing medical care independent of socioeconomic variables.
