Persuasión retórica en el discurso de las influencers en YouTube: recursos de intensificación elogiosa

Authors: Martínez Ezquerro Aurora
Published: February 2025

Young people use audiovisual content platforms and the field of social networks as common means of communication in which they publicly express their experiences or interests. Discursive practices–previously only reserved for professionals or qualified people– have become widespread in these new media, which constitute an interesting field of formative linguistic study. In this context, the hyper-connected generation Z brings together a large group of communicators or influencers who express their tastes by sharing «content» with their followers. In this research we analyze the discourse of young Spanish women of that generation through their fashion videos; they are short and spontaneous recordings that use strategies of rhetorical persuasion. The message of the products described by these stations is manifested with a constant attitude of praiseworthy intensification, and for this purpose they use morphological and lexical-semantic resources that emphasize their discourse.

On the issue of the qualification of the legalization (laundering) of funds or other property acquired by criminal means
Authors: Lubentseva Kristina Aleksandrovna , Yakovleva Elena Olegovna , Ivanov Pavel Ivanovich
Published: February 2025

In the modern criminal law system, the fight against the laundering of illegal income and criminally acquired property occupies a key position. By legalizing illegally obtained funds, criminals significantly complicate the work of law enforcement agencies in detecting and investigating primary crimes. At the same time, a number of problems, especially in the field of criminal legislation, hinder the effective opposition to this type of criminal activity. The subject of the research is the criminal law aspects of money laundering. The purpose of the work is to analyze the current state of legislation in the field of countering legalization (laundering), identify problems of law enforcement and develop proposals for improving criminal legislation. The research paper considers: statistics of those convicted under Articles 174 and 174.1 of the Criminal Code of the Russian Federation and the identification of discrepancies between the number of crimes and the number of persons brought to justice; problems in qualifying the actions of those accused of legalizing criminal funds and property; the need to prove the specific purpose of the offender; gaps in legislation regarding criminal prosecution for laundering criminally obtained funds abroad. The methodological basis of this work is the following methods: dialectics, induction, deduction, as well as statistical, formal and logical, as well as the method of regulatory analysis, which allow a deeper understanding of the problems of money laundering qualification. Results of the work – specific measures have been proposed to improve criminal legislation. Scope of application – the results can be used to improve the regulatory framework, as well as in scientific research in the field of criminal law. The scientific novelty of the study is expressed in the identification of problematic aspects and the need for amendments to Articles 174 and 174.1 of the Criminal Code of the Russian Federation, including the introduction of a minimum threshold for the amount of legalized funds and the establishment of administrative responsibility for laundering small amounts. It is also proposed to supplement the legislation with a provision on criminal liability for the legalization in Russia of proceeds from crimes committed in other countries. The conclusions that were formulated in the work emphasize that the existing legislation in the field of combating money laundering has a number of disadvantages that lead to low effectiveness in combating this type of crime.

A methodological approach to assessing the risk of fire hazard in large cities is considered. The problem is caused by the restriction of the intra-house territories of residential areas and the emergence of secondary problems in the form of the inability to reach the accident site of large-sized fire vehicles in case of an emergency. A systematic approach to improving the operational suitability of a residential area in the event of an emergency is presented. The main goal is to ensure the safety and patency of large-sized models of fire equipment. The use of a digital model is proposed to ensure the safety of the urban agglomeration. The results obtained using this methodology can be implemented into navigation applications for the fire service and ensure safety in modern agglomerations. Specific ways are presented by which the entire system can be modified to be able to intuitively change and select individual access routes in real time based on the current situation.

Introduction. Study of diverse problems coming from the theory and practice of economic competition and competitiveness of an enterprise (institution) is the subject of scientific knowledge. The topicality of the subject is assured sufficiently with existence of market economic relations. The goal of the research is a conceptual formulation and presentation of author`s understanding of the methodology of comprehensive analysis for building the competitiveness of an enterprise (institution). The objectives: 1) to describe the stages of comprehensive analysis for building the competitiveness of an enterprise  (institution); 2) to define the  logical and functional interrelationships between the stages of comprehensive analysis for building the competitiveness of an enterprise  (institution); 3) graphically present the stages of carrying out a comprehensive analysis for building the competitiveness of an enterprise  (institution). Methods and technics. The research is implemented within systems and dialectic methodology. Monographic analysis is the major research method, resulted in the synthesis of author’s presumptions and propositions. Interpretation of results and analysis. The analysis for building the competitiveness of an enterprise (institution) should include a  more extensive research programme, that could be named “comprehensive analysis for building the competitiveness of an enterprise  (institution)”. As indicated in this article, it integrates various techniques, joint and consistent  under general logical and functional interrelationships, use of which enables (to a high degree of accuracy and relevance) a guarantee of knowledge about the peculiarities for building the competitiveness of an enterprise  (institution)  in diverse fields (economic activities). Conclusions. Against the background of objective multiparadigmatism in social sciences as a whole and in the economy in particular, it is obvious that the offered programme of comprehensive analysis for building the competitiveness of an enterprise (institution) should not be considered as a completely finished methodological concept. Development of economic science and changes in economic practices leave open the possibilities for transformation and enhancement of any programme for study the  economic entities and processes.

Introduction. In various areas of human activities (medicine, technology, etc.), there are quasiperiodic processes. Their study and analysis require adequate statistical simulation models. The properties of theoretical models, for instance, the typical Gaussian random process, usually do not fit the processes in question. Thus, it is imperative to build models by the observed implementations of the processes. The aim of the research was to study the possibilities of application of Markov model for modeling differential rhythmogram. It seems rather promising to apply simple Markov model of a random process, which transition probability matrix contains a large number of parameters that can be estimated by the received process implementations. Conclusions. The model allows to display a variety of statistical and correlation properties. It is enabled to integrate estimates of the transition probabilities of the model by the onetype implementations of the random processes. Markov model can be employed in problems of classification of random processes by observed implementations. Analysis of the time properties (rhythmograms) of quasiperiodic processes and their modeling is conveniently carried out with the use of differences of adjoint periods (differential rhythmograms).

В КВ-диапазоне на работу различных радиотехнических систем негативное влияние оказывают сосредоточенные и флуктуационные помехи, фильтрация которых необходима при организации оптимального приёма. Повышение эффективности работы систем требует развития алгоритмов автоматического обнаружения сигнала. Обычно фильтрация помех при приёме осуществляется после демодуляции. Однако преддемодуляционная фильтрация имеет свои преимущества, особенно в случае применения сигналов с расширенным спектром. В этой связи в работе представлены новые алгоритмы фильтрации помех, способствующие увеличению энергетического выигрыша при приёме широкополосных сигналов. Представлены результаты проведённых натурных экспериментов по верификации данных алгоритмов при зондировании трассы о. Кипр г. Йошкар-Ола.

Introduction. Currently, image processing for getting additional information on the object in question is topical for research. In particular, there is a problem of extracting information on parameters of multiple ionospheric HF radio channels from ionograms, obtained by ionosphere sounding. The problem is that the images are corrupted with noise, because a sounder receiver encounters interference signals of different physical origin. It shall be noted that quite a lot of research into the ionograms processing were carried out. In our studies we proposed to apply methods of computer filtration of images. The aim of the research was the development and study of the algorithms of interferences filtration at the wideband signals reception in systems of diagnosing ionospheric HF communication links with the use of SDR technology. Findings. Paper presents the scientific justification of the algorithm of adaptive whitening of noise in HF band at the LFMCW signal reception. Software implementation of the developed complex algorithm of ionogram image processing is presented. Full-scale experiments were carried with the use of the developed facility with the LFMCW signal based on the software-defined radio technology. In further research, it is planned to perform experiments on studying the efficiency of whitening in the case of high levels of the LFMCW signal.

Introduction. Currently, the stage of development and testing of special-purpose antennas often poses a necessity to control their aperture distributions with the use of the general-purpose equipment. Despite the significant achievements in this area, antenna diagnosing is still topical, especially due to the use of hybrid-mirror antennas in state-of-the-art active antenna arrays (AAAs). For these purposes, a large number of different techniques have been proposed, developed, and are being used. First of all, these are direct measurements of amplitude-phase distributions (AFD) in the antenna aperture. There are a large number of methods for measuring these values and devices for their implementation. Carrying out the indicated measurements directly in the aperture or at least at a small distance from the antenna is technically impossible in some cases that are important for practice. For these cases, there were proposed methods that are based on measuring the parameters of the electromagnetic field of the antenna in the near field zone with the subsequent measuring the desired AFD by the appropriate data processing. Currently, not only are developed methods for measuring radiation patterns in the far field zone, but also the relevant software and hardware. The aim of the research is to improve the algorithm for reconstructing the AFD of the antenna with the use of the measurements in the near field zone. The modification of the restoration method consists in the fact that previously there was used a model representation of the sensor radiation pattern (a virtual array element) in the form of the function as well as there were proposed recommendations on choosing the step, electric dimensions and focal length of the virtual array to minimize the deviation of the measured AFD from real one. In fact, the sensor radiation pattern (typically, the open end of a standard waveguide is used) is somewhat different from the model. Findings. It is shown that the use of a model of radiation pattern reduces the quality of reconstruction by the focusing method. The difference between the reconstruction results using the model and the real RP decreases with the increase in the relative focal length z0/Lап and becomes negligible at z0/Lап 0.50.75. Conclusion. So, measurements of asymmetric AFD, as well as at small focal lengths, require the use of as accurate as possible sensor RPs, that are measured experimentally or calculated with the use of reliable electrodynamic modeling procedures.

Introduction. In the processing of dynamically changing data, for instance radar data, the presentation of various data arrays containing information on the routes and signs of air objects is crucial. In the practical implementation of the computational process, it seemed natural that finding the necessary information on a specific airborne object, updating and processing into data arrays was traditionally carried out by the element-by-element search method. At the same time, the representation of data arrays in the form of matrices and the use of matrix algebra provide a good opportunity to form the optimal calculations in tertiary processing. Theoretically, calculations with data arrays represented by matrices allow to eliminate element-by-element enumeration of data and yield output data immediately in the form of array. The formation of matrices and actions with them require a significant computational resources, therefore, one can assume a certain gain in computation time if there is a large amount of data in arrays, at least several thousands. The aim of the research was the development of algorithms for replacing dynamically changing data in arrays based on the mathematical apparatus of matrix algebra and the study of their application limits. A certain example of a tertiary network processing algorithm for radar information shows the sequence of the most frequently repeated operations, such as searching and replacing an array element.

Introduction. The existing methods for calculating thin-film interference filters are based on the priori known data on the thickness and refractive index values for each layer. The increasingly widespread method of magnetron sputtering for producing thin-film interference filters exhibits a number of features - one of them is that the refractive index of a thin film can vary within a fairly wide range. Thus, the aim of the research, which is to experimentally measure the optical transmission spectra of graphite, aluminum nitride and copper oxide films of various thicknesses, produced by magnetron sputtering, is topical. To achieve the aim, a number of tasks were posed: 1) Studying transmission spectra of thin films of aluminum nitride (AlN), copper oxide (CuO) and graphite (C) of various thicknesses, produced by magnetron sputtering; 2) Measuring thickness and surface structure of the thin films with the use of atomic force microscopy; 3) Studying transmission spectra of combinations of the produced films. Experimental technique. AlN, CuO, C thin films of various thicknesses were produced on K-8 glass substrates by magnetron sputtering. The transmission spectra of the thin films were recorded with the use of the SF-2000 spectrophotometer. Findings. Studies showed that graphite films change their optical characteristics, in particular, the short-wavelength boundary of the transmission spectrum at 218 nm, depending on the thickness in the range from 125 to 350 nm. These changes can be caused by the change in their crystal structure during growth. On the other hand, in AlN and CuO films produced by the method of reactive magnetron sputtering, this tendency was not observed, despite the fact that the range of thicknesses of these films overlaps the range of thicknesses of carbon films. These films are characterized only by a decrease in the transmittance with an increase in their thickness. The obtained transmission spectrum for combinations of aluminum nitride and copper oxide with graphite films allows to shift the transmission boundaries in the short-wavelength and long-wavelength parts of the spectrum and, due to this, increase the selectivity of the spectra of these thin-film structures.

Introduction. Currently, systems with dynamical chaos are used to describe nonlinear processes in various fields of physics, biology, engineering, and radioelectronics. Generation of pseudorandom sequences based on the chaotic system is topical for state-of-the-art data transfer systems. The aim of the research is to analyze the relation between the high order Lyapunov exponent and the statistical characteristics of binary pseudo-random signals formed on the basis of dynamical Lorentz and Chua systems under conditions of quasi-resonant effects on the time grid parameters. Findings of the mathematical modeling. The statistical characteristics of pseudo-random signals which are generated on the basis of dynamical Lorentz and Chua systems with quasi-resonant effect were analyzed. The high order Lyapunov exponent for different variations of the modulation depth was estimated. The probabilities of passing the FIPS 140-2 tests were calculated. Conclusions. As a result of the work, there was established a qualitative relation between the high order Lyapunov exponent of the dynamical systems of Lorenz and Chua and the statistical characteristics of binary pseudo-random signals formed on their basis under conditions of quasi-resonant influences on the time grid parameters.

Problem statement. Protection against interferences is one of the main problems of radio engineering, radio physics, various communication systems and other technical areas of data transmission and reception. Various organizational and technical measures have been developed to reduce the harmful effect of interferences. However, the rapid increase in the number of communication systems and especially in the presence of a cluster of interferences, including deliberate ones (radio jamming), have boosted the urgency of the problem. The aim of the work is to show that digital communication systems open up new opportunities towards the high noise immunity of useful signal reception: in particular, the use of nonlinear processing of a signal and noise mixture in a demodulator, followed by narrowband filtration at the second harmonic of the carrier of the useful signal. Findings.There is carried out an analysis of the noise immunity of a communication system with binary amplitude-shift keying (BASK) during the tuning to the second harmonic of the useful signal before the detection of an additive mixture of signal, Gaussian noise and narrowband interference. The results of computer simulation are presented. It is shown that tuning to the second harmonic significantly improves the noise immunity. Practical significance. The proposed method for processing a useful signal in the presence of a cluster of interferences can be used as a basis for the development of promising systems for data transmission and reception.

Introduction: Alongside the development of the Internet, network security has become a crucial requirement. Bugs in software and operating systems result in an increasing number of previously unknown intrusions discovered every day. The harm caused by these intrusions is becoming more and more dangerous. Firewalls can't ensure a complete protection of the network, because they prevent external threats and don't maintain internal attacks. Intrusion detection systems (IDS) solve this problem. The aim of the research is to develop a model of a hybrid intrusion detection system that will use a combination of improved detection methods based on anomalous and signature approach to increase detection accuracy and reduce the level of false alarms. Tasks: development of an improvement for the signature detection method, development of a unique anomaly detection method, development of a unique hybrid model of the intrusion detection system. Methods. To improve the signature detection method, we used machine learning, in particular the C5 algorithm, as well as decision trees. In addition to this, there are presented: storing signature rules with their partial structure in the MongoDB database, the process of clustering rules, building and detecting with the use of a decision tree. There are presented a unique method for detecting anomalies in network traffic with the use of machine learning methods and the theory of finite automata. Besides, there are shown: the detection process with the use of the sliding window technique, machine learning and time automaton; storage of trained models in the MongoDB database, the process of loading anomalies into the signature database with the use of RabbitMQ. Findings. The hybrid IDS with increased detection accuracy and reduced false alarm rate was developed. The developed system was compared with the well-known open-source solutions Snort and Suricata. The signature detection method was improved with machine learning and decision trees, and a unique anomaly detection method that uses machine learning and a time automaton was presented. It allows to detect previously unknown attacks. The practical significance of the work is the partial implementation of the developed system for the Infologistik24 LLC company.

Introduction. Current experience in the synthesis of nanotubes and the study of their electronic properties, as well as successful implementation of nanoelectronic elements based on them, have risen the necesity to select nanotubes of the required structure to supply appropriate enterprises; the selection is made according to the diffraction patterns of nanotubes in the field of an electron microscope. The most important structural parameter of a nanotube, which determines the nature of its diffraction pattern, is the polytype modification, which depends on the mutual packing of the layers. Meanwhile, the available descriptions of coaxial cylindrical gratings are fragmentary and unsystematic, and there is no complete nomenclature of their polytypes. The aim of the research was to develop a concept for constructing polytype modifications of ordered coaxial nanotubes based on their unfolding with the use of the approach of traditional crystallography of flat layered crystals. Thus, the objectives of the study were to identify the nomenclature of possible polytypes, their correct crystallographic determination, and to obtain the cylindrical coordinates of atoms. An analysis of the problem allowed us to distinguish three groups of polytype modifications of right-handed and left-handed multilayer cylindrical gratings: chiral, shear, and radial. We obtained cylindrical coordinates of atoms of the indicated polytype modifications of the coaxial nanotube. Conclusions. Three groups of T-layer polytype modifications of ordered coaxial nanotubes have been identified: chiral, shear, and radial; their unambiguous crystallographic definition and cylindrical coordinates of atoms have been obtained. Research findings allowed to select nanotubes of the required structure, where the chiral polytype determines, among other things, the types of conductivity of the tube layers, the shear polytype determines the spatial symmetry group, that is, the nature of the electronic spectrum, and the radial polytype determines, among other things, the band gap.

В статье предложена экспериментальная схема применения квантового ключа в традиционной системе видео-конференц-связи. В соответствии с этой схемой, в традиционную систему видео-конференц-связи был встроен квантовый шлюз. Благодаря этому данные, передаваемые через систему видео-конференц-связи, могут быть зашифрованы квантовым ключом, генерируемым таким шлюзом. Небольшая скорость генерации квантового ключа компенсируется применением процедуры его расширения, что позволяет сохранять нормальное качество видеоизображений.

Introduction. Ensuring the security of video conferencing (VC) against various forms of attacks is crucial. Utilizing quantum communication for generating encryption keys presents a potential solution for enhancing the security of video conferencing. This research aims at developing a comprehensive design for a secure video conferencing system that incorporates both classical and quantum communication. The primary objectives involve designing a classical video conferencingsetup, integrating tools for establishing a quantum data transmission channel, selecting an efficient and versatile quantum key distribution (QKD) protocol, and addressing the challenges of matching data transfer rates and encryption key generation while maintaining video quality. Methodology. The adoption of QKD technology is proposed to achieve secure video conferencing due to its inherent data transmission security. A dedicated key generation algorithm is proposed for this technology. Results. The creation of a simple video conferencing topology involved the integration of a three-node quantum communication network with a classical network. In the context of a video conferencing system, a "one-time pad" mechanism was proposed for implementing quantum keys. An evaluation of the key consumption volume for video conferencing revealed an insufficiency in key generation volume. To address this limitation, a key expansion procedure based on the "sliding window" principle was introduced to meet system's requirements. The algorithm's efficacy in video data transmission was assessed by analyzing the impact of the quantum key error rate on the quality of video image transmission. The quality of video images was measured using the peak signal-to-noise ratio (PSNR) for both the original and decoded images. The findings showed that the quality of video images remained acceptable before and after encryption and decryption. Conclusion. The feasibility of utilizing a quantum key within video conferencing systems has been successfully demonstrated. This serves as a foundational concept for establishing more intricate video conferencing systems incorporating quantum key encryption.

Целью исследований являлось определение оптимальных способов предпосевной обработки семян сосны обыкновенной и повышения плодородия почвы в лесном питомнике Северного филиала Республиканского лесного селекционного центра, расположенного в Акмолинской области. При изучении качества семян выявлено, что они давали дружные всходы и энергия прорастания практически не отличалась от всхожести. Первые ранги по всем изученным показателям роста сеянцев заняли варианты опытов с поливом почвы Гуматофосфатом и ЭридГроу, и посевом сухих семян. Определено, что повышение плодородия почвы путём внесения ростовых веществ больше влияет на рост сеянцев, чем только замачивание семян в стимуляторах в ходе предпосевной обработки, хотя неплохие результаты показывают и данные варианты.

The goal of the research.The purpose of the studies was to determine the optimal methods of presowing processing of the seeds of Pinussylvestris L. and to increase the fertility of the soil in the forest nursery. Objects Oneyearold see dlings of Pinussylvestris L. grown from the improved selective seeds in the nursery of Northern branch of Republican Forest Selection Centre, located in Akmola region, were the object of the studies. Results. When studying the quality of the seeds it was revealed that they gave quickly developing plantlets and the energy ofintergrowth almost did not differ from the germinating ability. The variants with steeping of the seeds in Humatophosphate Trichocyne for 122 hours (93), Humate 7 for 6 hours (91), in Baikal Trichocyne (1 2 hours) (90) and Humate 7 Trichocyne (62 hours) (90) hadthe maximal laboratory germinating ability. The variants of the experiment, having high laboratorygerminating ability of the seeds, also differed by big indices of the height of the seeds. It indicates a prolonged effect of presowing cultivation of the seeds including on the growth of the seedlings. The variants of experiments with watering of the soil byHumatophosphate and AridGrow and sowing of dry seeds took the first ranks on all the studied indices of growth of the seedlings. The seedlings which were grown from the seeds steeped in Baikal (1.5 hours), Zircon (3 hours), Zircon Trichocyne (62 hours) andHumatophosphate (12 hours) had bigger values of height, length and mass of stipes and roots. Conclusions. It was determined that the increase of fertility of the soil by means of application of growth substances influenced more upon the growth of the seedlings than only steeping of the seeds in stimulants in the course of presowing processing, although these variants showed quite good results.

Приведены данные лабораторных исследований по поиску растительных препаратов, обладающих антибактериальным действием. Обнаружено наличие высокой чувствительности четырёх видов бактерий (Escherichia coli C 600, Pseudomonasae ruginosa, Salmonella, Bacillus cereus) к водному раствору спиртового экстракта коры осины (Populus tremula L.), который можно рекомендовать в качестве перспективного источника биологически активных веществ. Установлены значения минимальной подавляющей концентрации (МПК) препарата для всех исследованных микроорганизмов.

Introduction. The work was aimed at studying the antimicrobial activity of aspen extract, which has an antibacterial effect depending on the boundary values (herbal medicinal raw materials taken from four test areas in relation to the cardinal directions). The problem of the influence of secondary metabolites in relation to the sides of the tree trunk light on the antimicrobial activity of the Populus Tremula is not touched upon. The aim of the study is to compare the antimicrobial activity in the extract of the aspen bark (Populus tremula) with respect to the cardinal directions for further rational harvesting of bark with a high content. Materials and methods. As the object of study, samples of aspen bark of Populus tremula, harvested by hand from different sides of the tree trunk in AugustOctober 2016 in the Shulka forest area of the Orsha district of the Republic of Mari El, were used. Results. The study revealed the effect of aspen bark extract on the growth of strains of microorganisms (gramnegative bacteria Escherichia coli C600, Pseudomonasae ruginosa, Salmonella and grampositive Bacillus cereus), which increased in proportion to the concentration of rutin in the cells. Significant antimicrobial activity of the extract is due to its high content of phenolic compounds such as rutin. In the studied aspen bark, taken from the North side, the content of flavonoids in terms of rutin was 0.196 , which in relation to other parts of the plant bark, is higher. It can be assumed that the flavonoids that make up the extract of aspen, determine its significant antimicrobial properties. The least inhibitory effect on the growth of strains of microorganisms was observed in the extract of aspen bark collected from middleaged plants (trial area 2), which suppressed the growth of microorganisms only at a high concentration of 6. Conclusion. It is of interest to further study the mechanism and spectrum of antimicrobial action of aspen bark extract, as well as the direction of selection of extraction conditions under which the sum of the isolated substances will have maximum antimicrobial activity. Aspen bark extract can be recommended as a promising source of biologically active substances with antimicrobial activity, which can be used as a prevention of infectious diseases, both animals and humans.
