Authors: Druzhinina I. E.
Published: April 2024

The article aims to study partially or completely lost industrial facilities designed by Nikolay Boykov and built in the 1920s in the Irkutsk Region that represent historical, cultural, and architectural value. In the work, such methods as retrospective analysis, historical reconstruction, and cluster analysis were used. The retrospective analysis was applied to study the territories of industrial facilities, which were occupied by some structures prior to Nikolay Boykov’s involvement; the architect’s contribution to the construction of new buildings and reconstruction of existing structures was ascertained; the design and construction time frames of Nikolay Boykov’s projects were revised. The cluster analysis revealed some quantitative and qualitative characteristics of three main industrial facilities that were designed by the architect under the conditions of modernization and new construction. The study of the years of Boykov’s activity revealed stages in the construction and reconstruction of industrial facilities (“Sibiromongol” leather factory, CPS-2, and Khaitinsky porcelain factory), and identified buildings that were most likely to have been designed with his involvement. The present author used archival documents and open sources to reconstruct and prepare layout plans of workshops at the “Sibiromongol” leather factory and Khaitinsky porcelain factory during the years of Boykov’s activity. The study of these facilities showed the value of the considered projects, the necessity of preserving the deteriorating structures that constitute a stratum of cultural, architectural, and historical development of industrial facilities from the early 20th century in Russia.

Authors: Alekseenko V. V. , Gonzhitov A. B. , Bugdaev S. P.
Published: April 2024

The present article aims to create polyvinyl chloride composites used in polymer hoses, to study their composition, as well as physical and mechanical characteristics. Polyvinyl chloride is a waterinsoluble material, resistant to weak acids, alkalis, alcohols, and mineral oils. The main characteristics limiting the use of flexible polymer hoses include elasticity at low temperatures and bending resistance at positive temperatures. Hose flexibility is determined by the properties of plasticized polyvinyl chloride together with its ultimate elongation at break and thickness. To study the properties of modified polyvinyl chloride, a MiniTPA-100 extruder was used to create test samples. The samples were cooled in a special refrigeration chamber. Elasticity measurements were performed employing a standard tensile testing scheme on an Instron 5980 testing machine. The measurements were taken at 20 °C, -40 °C, and -50 °C. The investigation of the compositions of polymer composites was conducted using extraction methods with various solvents. These studies enable one to evaluate the properties of polymer composites. Before testing, the samples were held at specified temperatures. The strain rate equaled 3 mm/sec for all samples. The proposed laboratory techniques give an opportunity to evaluate most of the performance characteristics of polyvinyl chloride composites. The obtained results indicate that the performance characteristics of flexible polymer hoses can be fully predicted based on laboratory testing of the materials composing the hose. The results also confirm the potential of work on polyvinyl chloride modification using thermoplastic elastomers.

Effect of Technical Safety Regulations on Form-Making in Russian Architecture on the Example of the Mountain Dwellings by BIG in Denmark
Authors: Khadeev M. B.
Published: April 2024

The article assesses the effect of technical regulations on form-making in Russian architecture. The first part describes an outstanding architectural object, the Mountain Dwellings in Copenhagen. It consists of a housing block and parking spaces located both under the residential part and on the same level as apartments. This arrangement is unusual and spectacular, while the apartments are comfortable. In Denmark, this solution is recognized as safe and environmentally friendly. The second part of this article considers this project from the perspective of Russian building codes and regulations. Certain fire and sanitary regulations are shown to make such an architectural approach impossible or, to be more precise, dictate only standard design solutions. The Russian construction industry is over-regulated, restricting architects from creating new design solutions that are acceptable in Denmark. In addition, a large number of architectural solutions used in global construction cannot be realized or are difficult to implement under our conditions. Russian architects are denied many of the tools to create expressive space and form. It seems necessary to involve architects in the validity analysis and development of building codes.

Published: April 2024

The present work is aimed at analyzing the heating system operation in academic building No. 7 and developing measures to modernize this system with an evaluation of economic efficiency. The analysis involved a thermal analysis of exterior wall envelopes, an on-site inspection of the heating system, as well as measurements of internal microclimate parameters and thermal imaging. Heat losses in rooms were calculated, and a verification hydraulic analysis of the heating system was performed. The inspection revealed deficiencies in the operation of the existing heating system, and two options for modernization measures were developed to address these deficiencies. The first option consists in adjusting the system (removing and adding sections; replacing window seals; replacing piping with that of a different diameter; installing manual balancing valves on risers and branches; installing a pump on the return piping; installing closing sections). The second option involves major repairs and includes additional measures (in addition to those specified above) to insulate the attic flooring and end walls of the building, which can reduce heat losses by 25 %. For both options, automated heating substation equipment was selected. In addition, costs were estimated, economic efficiency was evaluated, and payback periods for each measure were determined. The on-site inspection of exterior wall envelopes and the heating system, as well as measurement of microclimate parameters, provided a means to develop measures to modernize the heating system of academic building No. 7 and evaluate economic efficiency.

Authors: Baranova A. A. , Egorov E. V.
Published: April 2024

The study aims to determine the compressive strength, as well as linear and volumetric deformations of autoclaved aerated concrete with an average density of 600 kg/m3 after holding at temperatures in the range of 100–800 °C. The compressive strength of test samples was determined using an IP-100 hydraulic press in accordance with the state standard GOST 10180 “Concretes. Methods for determining the strength of control samples” State Standard. It was experimentally established that after holding aerated concrete samples at a temperature of 100 ºС, its compressive strength increased by 6.2 %, which is associated with the loss of an excess moisture during heating. A further increase in the temperature to 600 ºС insignificantly affects its strength characteristics. At an increase in the test temperature to 800 ºС, the residual compressive strength of samples averaged 62.6 % of the control sample strength. Linear dimensions of samples begin to vary at a temperature of 300 ºC and do not exceed 1.56 % of initial values up to a temperature of 600 ºC. A further increase in the temperature to 800 ºС reduces the linear dimensions of aerated concrete samples by 15.15 %. Volumetric deformations of autoclaved aerated concrete samples in the temperature range of 300–600 ºС are less than 5 %, while, for the temperature of 700–800 °С, they range from 25 % to 38.9 %. The studied aerated concrete can withstand high temperatures up to 600 °C without significant variations in its physical and mechanical characteristics.

Authors: Prodous O. A. , Shlychkov D. I. , Chelonenko A. G.
Published: April 2024

The article aims to classify the condition of sewerage systems made of different materials and having different diameters with a build-up of deposits in the bench part; this analysis is based on their televising and analyzing the values of hydraulic characteristics. The analysis of televising data and the hydraulic potential of pipes establishes the class of a pipeline having internal deposits, which is used to decide on the continuation of operation, the need for preventive measures, including mechanical or hydrodynamic cleaning of the system, or the method of its reconstruction. Noteworthy is that by determining the hydraulic efficiency factor of sewerage systems with different deposit layer thicknesses in the bench part of pipes, a range of this coefficient can be established (in tabular form), which, regardless of the diameter and type of pipe materials, can be used to make a decision on continuing further operation, carrying out preventive measures (mechanical or hydrodynamic cleaning), or removing it from service for reconstruction. Also, recommendations are provided on the possibility of continuing or discontinuing the operation of wastewater pipelines with internal deposits. It is proposed to classify the operating condition of sewer pipelines with deposits in the bench part to make decisions on the need for restoring the throughput capacity, reconstruction, or replacement of pipes.

Authors: Montero Sol
Published: April 2024

El ascenso de Javier Milei en Argentina se produce en una sociedad políticamente polarizada y afectada por emociones negativas. Este trabajo propone explorar el modo en que los afectos se movilizan y se ponen en escena en las redes sociales de Milei. A partir de un trabajo de campo que recogió más de mil publicaciones en las cuentas oficiales de X, Instagram y TikTok durante la campaña presidencial (entre agosto y noviembre de 2023), se intenta caracterizar el dispositivo emocional desplegado por las cuentas de Milei en sus redes. Se examina la movilización de dos emociones: por un lado, el resentimiento (asociado al asco y a la humillación) desplegado en las interpelaciones, menciones y citas en X (exTwitter); por otro, una serie de emociones positivas que contribuyen a la identificación y a la construcción de un “nosotros”, movilizadas por la iconografía audiovisual en Instagram.
Calibration of intermittent water supply systems hydraulic models under data scarcity
Authors: Leinæs Ane , Simukonda Kondwani , Farmani Raziyeh
Published: April 2024

Intermittent water supply systems (IWSSs) are unable to meet customer demands due to water scarcity from the sources or due to economic or/and technical scarcity. Conversion to continuous water supply as a means of tackling IWSSs’ inherent problems of inequitable water distribution, limited water supply hours, high non-revenue water, system operation and maintenance costs, and poor water quality is essential for sustainable water supply. Modelling and optimisation techniques have been used to aid the conversion process, optimisation of the operation of these systems, and guiding leakage reduction actions. However, modelling IWSSs have several challenges. These include the lack of accepted existing modelling techniques that include leakage modelling and the lack of comprehensive methodology for calibrating IWSS hydraulic models under limited calibration data. This study proposes a methodology for calibrating IWSS hydraulic models that include leakage modelling. The proposed methodology involves distinct steps to mitigate the problem of data scarcity, it eliminates the trial-and-error procedure of determining the leakage emitters' coefficients by using optimisation and it presents an approach for estimating the lower and upper bounds of the emitters' coefficients. The methodology was applied to a case study in Zambia. The calibration procedure gave accurate results given the limitation of data.

Published: April 2024

Mempawah River Basin (DAS) is a water resource for the people of Mempawah and Landak Regencies. The community uses the Mempawah River as the main medium for agricultural needs, plantations, and the rearing of fish for consumption. Awareness of health that comes from water with its various uses, there has been consumer anxiety when consuming air along with agricultural and fishery products that are relevant to water use in the Mempawah watershed. This phenomenon occurs because the water resources of this watershed area have been polluted by mercury as a result of unlicensed gold mining activities in its spatial extent. This research was conducted to analyze the level of mercury pollution in the river basin, due to illegal gold mining activities. The method applied was purposive sampling, through 29 water sample points located in the upstream, middle and downstream. The sample results were explained using the Atomic Absorption Spectroscopy (AAS) tool. Then, from a spatial perspective, the location of PETI activities was analyzed spatially using Spatial Dynamic Modeling Geographical Information System software with kriging interpolation techniques, to predict the distribution of mercury pollution. The results of the research show that in the middle part of the Mempawah watershed, there is mercury pollution from 0.0023mg/lt to 0.0083 mg/l and has exceeded the threshold determined by PP No. 22 of 2021. The upstream and downstream parts of the Mempawah watershed are not polluted by mercury, because the PETI activity point is only in the middle part of the Mempawah watershed. These findings provide suggestions that the allocation of Mempawah River water as the sole raw material for corporate entities and its use for growing fish communities should be more closely monitored, to avoid danger, due to the chain of heavy metal contamination in the form of Mercury.

Authors: Karamysheva N. S. , Milovanov A. S. , Mitrokhin M. A. , Zinkin S. A.
Published: April 2024

Purpose of research. The purpose of the work is to develop recommendations for the software implementation of cognitive agent-based systems that ensure interoperability in the interaction of software cognitive agents with different properties. A software implementation that determines semantic proximity based on machine learning can automatically and quickly highlight important key concepts and find associations, simplifying and speeding up the process of working with text data during a dialogue between agents, one of which is a human. The proposed approach is based on the assumption that computer systems can perform some “anthropomorphic” functions, similar to human ability to think.

Methods. Domain knowledge is determined by training an artificial neural network. To indicate the semantics of remarks and other information, it is proposed to use tagging and determining the semantic proximity of key phrases from speeches presented in written form.

Results. The system was implemented in the Python programming language. The Word2Vec model with Skip-gram architecture was used as a neural network model for text vectorization. For training, two text sets with information about computer science and zoology were used. Based on the results of comparing texts on two topics, one can judge the performance of the system to determine the semantic proximity of textual information.

Conclusion. The subsystem for determining the semantic proximity of text information based on machine learning technologies, which forms the basis for the software implementation of cognitive interoperable agent-based systems, will improve the efficiency of existing or developed applications that involve a large amount of text information.

Published: April 2024

Рurpose of this work was to optimize the process of obtaining powder materials for the production of carbide cutting tools by electrodispersing metal waste of TN20 alloy in water.

Methods. To carry out the planned studies, waste of sintered tungsten-free hard alloy of the TN20 brand was selected. Distilled water was used as the working fluid. On an experimental patented installation for the production of powders from conductive materials, waste of a tungsten-free hard alloy TN20 was dispersed in distilled water with a loading weight of 500 g. The following electrical parameters of the installation were used: capacitance of capacitors 60.0...62.5 UF; voltage at the electrodes from 120...140 V; pulse repetition frequency 120...140 Hz. The study of the shape and morphology of the surface of particles obtained by EED of waste of a tungsten-free hard alloy TN20 was carried out on an electron-ion scanning (scanning) microscope with field emission of electrons "QUANTA 600 FEG" (the Netherlands). The average particle size of titanium powder was studied using the Analysette 22 NanoTec laser particle size analyzer (Germany). Optimization of the processes of dispersion of waste of tungsten-free hard alloy TN20 was carried out by setting up a complete factorial experiment on the average particle size of the resulting erosive particles according to block diagrams.

Results. Analysis of the particle shape parameters of the carbide powder from images from a scanning microscope suggests that the electroerosive particles are mainly spherical in shape and agglomerates. It has been experimentally established that the average particle size of a carbide powder of 24.4 microns is obtained with a discharge capacitor capacity of 63 UF, an electrode voltage of 200 V, and a pulse repetition frequency of 200 Hz.

Conclusion. Carrying out the planned measures will solve the problem of recycling waste from TN20 alloy and their reuse in the production of cutting tools.

Authors: Kitaev D. N. , Bohan A. R.
Published: April 2024

Purpose of research. For settlements located in the permafrost zone on the territory of the Russian Federation, obtain the values of average annual water temperatures in heating networks of centralized heating systems separately for the supply and return mains using design water temperatures in the range from 95 to 150 ° C, taking into account modern climatic data and the indicators of the heating systems used devices.

Methods. To achieve the set goals, methods of central high-quality regulation of the load of the thermal energy consumer were used, based on the heat balance equation. To find the temperatures at the break point of the temperature graph, numerical methods for solving equations were used. To obtain an equation for the dependence of the average annual water temperature in the supply main of the heating network, methods of the theory of approximation of functions by algebraic polynomials were used. To cluster settlements according to the criterion of being in the permafrost zone and the possibility of using centralized heat supply, methods of analysis and synthesis were used.

Results. Average annual water temperatures for the supply and return lines of heating networks were obtained using central quality control schedules with design temperatures from 95 to 150°C, taking into account the values of average monthly outdoor air temperatures for settlements in the permafrost zone of the Russian Federation.

Conclusion. The values of annual water temperatures recommended by modern standards for the supply main of heating networks may differ significantly from the calculated values obtained taking into account the design water temperatures, climatic characteristics of the design area, and features of the organization of a closed heat supply system in order to ensure standard hot water supply temperatures. A quadratic equation has been obtained that makes it possible to calculate with high accuracy the design annual temperature of the coolant for the supply pipeline depending on the temperature schedule implemented in the heat supply system for settlements located in the permafrost zone.

The modeling showed how aperture size, tilt angle, absorption coefficient and bottom distance have a significant effect, and also revealed a linear relationship between the error coefficients affecting the displacement.

Conclusion.Amplitude-frequency offset studies showed that this phenomenon has a significant impact on the accuracy of Doppler lag measurements. Phased array instruments showed advantages within the long term accuracy framework. Comparison of the amplitude-frequency offset with experimental data revealed good agreement, which confirms the adequacy of the developed model. However, additional modeling is required to verify the influence of other error sources, such as territorial, side lobe coupling, beam alignment, etc., and to study in more detail the influence of roll on measurement accuracy.

Authors: Bondar O. G. , Brezhneva E. O. , Botikov K. A.
Published: April 2024

Purpose: study of a method for measuring temperature with a two-wire connection of a resistance thermometer (RT) using its mathematical model.

For a given range of measured temperatures, determine the type and parameters of the adaptive measurement algorithm model.

Methods: methods of mathematical modeling, numerical methods. When developing a mathematical model of the method, the theory of electrical circuits was used, in particular, the analysis of transient processes. When analyzing the proposed solutions, the impact of electromagnetic interference and quantization effects was taken into account, and the effectiveness was assessed by the relative error () of measuring the resistance of the vehicle and comparison with analogues. The simulation was carried out in the MATLAB environment.

Results: a mathematical model of an integrating method for measuring temperature using a TS was developed, the optimal value of the shunt capacitance was selected for the range of measured temperatures 0 ... 660 °C, providing within the range the calculated value of the root-mean-square error (RMS) of 0.02% -0.04%, the optimal value was determined first integration interval (4 ms). It is shown that for the adaptive measurement algorithm it is possible to select a linear model. The effectiveness of the method was assessed in comparison with the method of determining the resistance of the vehicle using two readings of the transient process.

Conclusion: The results of mathematical modeling of a method for measuring temperature based on estimating the resistance value of a vehicle based on the results of numerical integration of the transient discharge process of a capacitor connected in parallel with a resistor are presented, making it possible to optimize the algorithms underlying its operation, as well as to judge the effectiveness of the proposed solution. The two-wire method, based on determining the resistance of the vehicle based on the results of integrating the transient process when the power of the measuring circuit is turned off, makes it possible to increase the accuracy of temperature measurement comparable to the accuracy of three and four-wire circuits, eliminating the disadvantages associated with their complexity and high cost.
Multi-Objective Optimization of Active Hybrid Fluid Film Bearings Using Heuristic Algorithms
Authors: Fetisov A. S. , Litovchenko M. G. , Shutin D. V.
Published: April 2024

Purpose of research. The design of sliding bearings, especially for heavily loaded rotary machines, is a laborious task. The implementation of control systems for the movement parameters of the rotor further increases the complexity of a design procedure. The study shows a developed approach to the optimal design of active rotor bearings using heuristic optimization algorithms. The approach allows to obtain a set of optimal Pareto solutions and determine the only configuration of the reference node that best meets the given criteria.

Methods. The problem of optimal parametric synthesis of an active fluid friction bearing was solved using a numerical model coupled with the model of rotor movement in the support. For the given design problem, objective functions were formulated, design variables were determined, and the necessary restrictions were imposed. Using multicriteria versions of the genetic algorithm and the particle swarm algorithm, procedures for the optimal synthesis of reference nodes were carried out. The solutions obtained by different methods are compared and analyzed based on the results of model tests.

Results. As part of the study, algorithmic and software tools were developed for solving problems of optimal parametric synthesis of active hybrid fluid friction bearings. The applied objective functions are conflicting, so the primary result of the solution is a 3D Pareto front. The tested heuristic algorithms showed qualitatively similar solutions, but the genetic algorithm covers a larger range of them. On the whole, the final decisions meet the criteria, but the methods for making final decisions require additional elaboration.

Conclusion. The study presents an approach to the automated design of sliding bearings, which allows you to simultaneously take into account the tribological, dynamic aspects of the behavior of the rotary bearing system, as well as ensure readiness for the use of control systems in bearing nodes. The tested heuristic algorithms give comparable solutions to the optimization problem in comparable time as well. Further improvement of the method of parametric synthesis of such supports should be carried out in the direction of decision-making algorithms, refinement of objective functions, as well as acceleration of the applied calculation models.
Associative Field as a Model of Mental Representation: Cognitive, Emotive and Linguistic Aspects
Authors: Stepykin N. I.
Published: April 2024

Purpose of research. Modeling of the associative field in order to reflect the nature of the predication of speech action, represented by the cue – target pair, as well as to identify the dominant mental supports.

Methods. The construction of the associative field is based on the data of free association tests presented in the Russian associative thesaurus and the University of South Florida Free Association Norms. Modeling of the associative field involves the distribution of associates by the nature of predication to identify conceptual reactions, associates-representations, emotional and evaluative, and operational reactions. The established correlation of the types of associates makes it possible to identify the dominance of cognitive, emotive or linguistic guidelines in the production of speech action.

Results. Due to psycholinguistic modeling of the associative fields uchitel and teacher ethnocultural difference in the nature of the predication of speech actions was established. Reactions-representations dominate among American respondents, operational associates prevail among Russian ones. Russian speakers rely more on language norms, while Americans rely on cognitive guidelines. Emotive guidelines take an intermediate place between cognitive and linguistic ones. Associative field uchitel has 12% more emotional and evaluative reactions in comparison with the field teacher. The close distance of the psychological meaning of the words teacher and student is stipulated by the overlapping associations, such as school, professor, class and book. The associative fields uchitel and student do not have overlapping associates, which emphasizes the lack of common psychological meaning.

Conclusion. The conducted research made it possible to demonstrate the effectiveness and prospects of the psycholinguistic model of mental representation. It has been determined that the proposed model reveals the nature of predication in the cue – target relationship, as well as the prevailing guidelines of the internal lexicon and signs on the basis of which psychological predication is carried out.

Published: April 2024

Background

Evidence-based medicine (EBM) has the potential to improve health outcomes, but EBM has not been widely integrated into the systems used for research or clinical decision-making. There has not been a scalable and reusable computer-readable standard for distributing research results and synthesized evidence among creators, implementers, and the ultimate users of that evidence. Evidence that is more rapidly updated, synthesized, disseminated, and implemented would improve both the delivery of EBM and evidence-based health care policy.

Objective

This study aimed to introduce the EBM on Fast Healthcare Interoperability Resources (FHIR) project (EBMonFHIR), which is extending the methods and infrastructure of Health Level Seven (HL7) FHIR to provide an interoperability standard for the electronic exchange of health-related scientific knowledge.

Methods

As an ongoing process, the project creates and refines FHIR resources to represent evidence from clinical studies and syntheses of those studies and develops tools to assist with the creation and visualization of FHIR resources.

Results

The EBMonFHIR project created FHIR resources (ie, ArtifactAssessment, Citation, Evidence, EvidenceReport, and EvidenceVariable) for representing evidence. The COVID-19 Knowledge Accelerator (COKA) project, now Health Evidence Knowledge Accelerator (HEvKA), took this work further and created FHIR resources that express EvidenceReport, Citation, and ArtifactAssessment concepts. The group is (1) continually refining FHIR resources to support the representation of EBM; (2) developing controlled terminology related to EBM (ie, study design, statistic type, statistical model, and risk of bias); and (3) developing tools to facilitate the visualization and data entry of EBM information into FHIR resources, including human-readable interfaces and JSON viewers.

Conclusions

EBMonFHIR resources in conjunction with other FHIR resources can support relaying EBM components in a manner that is interoperable and consumable by downstream tools and health information technology systems to support the users of evidence.
focusing on diversity in a Multicultural employee group—The case of an Engineering Consultancy in London
Authors: Xanthakis Georgios
Published: April 2024

Despite the increasing research on work diversity, diversity itself remains an ambivalent term due to the various and in some cases even conflicting ways in which scholars conceptualize its nature (Janssens & Zanoni, 2005). A Literature Review of the relevant literature illustrates four main streams. The first one considers diversity as a concept with static nature and treats it as a measurable variable (Cox, 1993) while the second addresses the dynamic, socially constructed nature of diversity (Barinaga, 2007). A third stream of research explores both the dynamic and multiple nature of workgroup diversity while the last school acknowledges the dynamic, shifting relationship between the diversity categories focusing on issues of inequality and discrimination (Holvino, 2010).The aim of this study is to contribute to the current diversity research by exploring from an a posteriori direction how the employees in a multicultural group perceive their group diversity during their everyday working life. In doing so, a research is conducted in engineering consultancy, to explore how the employees actively construct their workgroup diversity. Above research, drawing on the assumption that reality is social construction (Berger & Luckmann, 1966) shows diversity and identity as socially constructed concepts that should be identified from an a posteriori direction. The research questions guiding the narrative analysis shows that members’ differentiation is dynamic and changes over time during their everyday project group life.

Energy resources play an important role in the process of organizing the national security of a state, which is why establishing control over them is one of the most important goals. That is why the countries of the Persian Gulf are the subject of interest of the leading states of the world, the epicenter of the struggle to secure control over the natural resources of the region. The Persian Gulf is an area of special interest in this direction because it is where the largest reserves of hydrocarbon resources in the world are located today.The Persian Gulf region includes eight states, of which, except for Iran, all countries are Arab (Iraq, Bahrain, Qatar, the United Arab Emirates, Kuwait, Saudi Arabia, and Oman). The vast majority of them have the largest deposits of hydrocarbon resources, which determines the great interest in them in the world.Since oil and natural gas have an important place in the modern world economy, the role of countries with these natural resources in world politics is also great. Since the countries of the Persian Gulf have the largest reserves of natural gas and oil in the world, it can be said that the strategic importance of this region will increase in the coming decades.The relevance of the research is also determined by the fact that the successful pursuit of the above-mentioned states' own strategic interests is facilitated by systematic intelligence activities. Along with this, the relevance of the research is defined by the fact that on the international level from a military-political point of view, the region is important due to the possibilities of deployment of military bases in the target states, including through intelligence activities, and to identify the threats expected from them.
De la cancelación al hipertexto: publicaciones periódicas culturales en la Cuba de entre siglos (1990-2010)
Authors: Rodríguez Reyes Roberto
Published: April 2024

Este artículo busca caracterizar el comportamiento de las publicaciones periódicas culturales en Cuba, entre 1990 y 2010, a la luz de la crisis que trajo consigo la disolución de la Unión Soviética. Partiendo del principio de que dichas publicaciones reflejan, en todos los aspectos que garantizan su existencia, las dinámicas, tendencias y fenómenos del acontecer socio-histórico-cultural, el trabajo explora y analiza la secuencia de cancelaciones, cierres, intermitencias y estrategias de resiliencia usadas por las revistas, tabloides, boletines y anuarios culturales en correlación con aspectos de orden económico, logístico, ideológico, social y estético. Basado en el examen de fuentes primarias y documentales, el estudio revela los procesos que llevaron a la diversificación de fórmulas y alternativas de gestión, la implementación de soluciones locales sobre las estatales, la emergencia de grupos literarios ajenos a instituciones oficiales, o el empleo del medio digital como nuevo soporte.
