¿Hacia una teoría de la administración en América Latina?
Authors: BALLINA RIOS FRANCISCO
Published: December 2021

El objetivo de este artículo es indagar qué tanto ha evolucionado la disciplina administrativa como técnica o como episteme, en el contexto latinoamericano. Se plantea que la teoría latinoamericana de la administración enfrenta una doble problemática: la epistemológica, por su falta de consistencia y coherencia interna, y la sociológica, debido a que su aparato conceptual está constituido de enfoques técnicos, ligados a procesos de producción a nivel mundial de corte pragmático-racionalistas; esta teoría administrativa, se fundamenta en el liberalismo económico, en modelos gerenciales provenientes en forma dominante de Europa y Estados Unidos, así como Japón. Asimismo, se busca describir sintéticamente hacia dónde se dirigen las agendas alternativas de investigación en administración para superar este escollo, mediante una conceptualización del papel que en nuestras sociedades   juegan las empresas y las organizaciones.
La transformación de valores en precios de producción: una contrastación empírica para el sistema capitalista
Authors: Maito Esteban Ezequiel
Published: December 2021

El objetivo del artículo es realizar una contrastación empírica global del llamado problema de la transformación a partir de los aportes recientes de Moseley. En función de ello, en la primera parte se realiza un desarrollo teórico inicial del valor y el precio de producción en consonancia con los desarrollos secuenciales y derivados que Marx realiza en El Capital. En la segunda parte, se realiza una contrastación empírica global tomando las diecisiete economías nacionales de mayor tamaño y 54 ramas de producción. Los resultados muestran que, al nivel de abstracción del valor, la tasa de ganancia desciende conforme la composición orgánica se incrementa y el nivel de la tasa de plusvalía no se relaciona con el nivel de la composición. En términos de precios de mercado vigentes en la realidad concreta —por el contrario—, la tasa de ganancia carece de asociación con la composición orgánica, nivelándose en torno a la tendencia establecida por los precios de producción marxianos mediante una fuerte correlación positiva entre tasa de plusvalía a precios de mercado y composición orgánica tal como lo establece la teoría marxiana.

“A Conviction about What is Moral or Lawful” Carl Schmitt on humanitarianism, the humanum, and the possibility of a “universal jus commune”
Authors: Hiromura Nicholas
Published: December 2021

Carl Schmitt (1888-1985) spent much of his life arguing against human rights. While this may not come as a surprise, a closer examination of The Concept of the Political reveals that Schmitt’s critique of Liberal humanitarianism is itself rooted in a concept of the humanum as a sphere of substantive moral and political conflict. As an analysis of Schmitt’s concept of the enemy shows, this humanum serves as an argument for the necessity of a juristic distinction between enemy and foe. For, only by distinguishing between the relativized enemy and the absolute foe, Schmitt argues, will we be able to distinguish create a space for particularly political action. Having revealed the framework of mediated moral conflict, in which Schmitt conceives of political action, I then turn to consider Schmitt’s minimalist proposal for a positive definition of a “universal jus commune” and assess its significance for a discussion of human rights.
Moore against the sceptics
Authors: Azzouni Jody
Published: December 2021

Moore’s “Proof of an external world” and his “Four forms of scepticism” have long puzzled commentators. How are these adequate responses to sceptics? How, for that matter, is the so-called proof of an external world even pertinent to the challenge of scepticism? The notion of relativized burdens of proof is introduced: this is a burden of proof vis-à-vis one’s opponent that one takes on when trying to convince that someone of something. The relativized burden of proof is a making explicit (in the topic of rational discourse) the truism that if you argue with someone with the intent of trying to convince that someone of something, and if you fail to, you have not met your own conversational goal. Assuming Moore is implicitly relying on the notion of relativized burdens of proof illuminates his approach in these papers.
Neo-Pyrrhonism, Empiricism, and Scientific Activity
Authors: Bueno Otávio
Published: December 2021

Pyrrhonism involves the inability to defend claims about the unobservable world, or, more generally, about what is really going on beyond the phenomena (SEXTUS EMPIRICUS, 1994). As a result, the Pyrrhonist is not engaged in developing a philosophical doctrine, at least in the sense of defending a view about the underlying features of reality. The issue then arises as to whether the Pyrrhonist also has something positive to say about our knowledge of the world, while still keeping Pyrrhonism. In this paper, I develop a positive neo-Pyrrhonist attitude, indicating that we can use this attitude to make sense of important aspects of science and empirical knowledge. To do that, I explore the connection between this revived form of Pyrrhonism and contemporary versions of empiricism, in particular constructive empiricism (VAN FRAASSEN, 1980, 1989, 2002, 2008). Although constructive empiricism is not a form of skepticism, there are important elements in common between constructive empiricism and Pyrrhonism. The resulting form of Pyrrhonism suggests that there is something right about the original stance articulated by Sextus Empiricus, and that suitably formulated it provides an insightful approach to think about empirical knowledge (PORCHAT PEREIRA, 2006, for the original inspiration behind neoPyrrhonism).
Dogmatism and Ampliative Inference
Authors: Brogaard Berit
Published: December 2021

The evidential role of experience in justifying beliefs has been at the center of debate in philosophy in recent years. One view is that experience, or seeming, can confer immediate (defeasible) justification on belief in virtue of its representational phenomenology. Call this view “representational dogmatism.” Another view is that experience confers immediate justification on belief in virtue of its relational phenomenology. Call this view “relational dogmatism.” The goal of this paper is to pit these two versions of dogmatism against each other in terms of their ability to account for ampliative, or non-deductive, inferential justification. I will argue that only the representational view can provide a plausible account of this type of justification.

This study is devoted to the problem of numerical modeling of the conjugate heat transfer in a closed-type power installation. The working elements of that are ribbed bimetallic tubes using the openFoam toolbox. The heat transfer process modeling in bimetallic tubes is associated with solving the problem of determining the value of the contact thermal resistance at the metal / metal interface. Considered design of a bimetallic tube involves crimping copper washers on the surface of an aluminum cylindrical tube. Hence, the contact surface of the tube is not isotropic in its properties. A mathematical model of conjugate heat transfer for air / bimetal / coolant medium is proposed. The features of the organization of thermophysical processes at the metal contact interface and at the metal / air and metal / coolant medium are shown. A qualitative comparison of the obtained results with the famous experimental data is carried out. Generalized temperature profiles in the rib longitudinal section are obtained by mathematical modeling. The given distributions of temperature and heat flux make it possible to estimate the contribution of each individual rib to the investigated heat removal process from the air environment. The efficiency of the considered technology of manufacturing a bimetallic finned tube is shown.

Authors: Ilmiani Aulia Mustika , Wahdah Nurul , Mubarak Mahfuz Rizqi
Published: December 2021

Albert Bandura's social cognitive theory is a theory that connects behaviorist and cognitive learning theory. This theory assumes that people can pay attention to others through observation, reinforcement, and modeling to learn new information and behavior. Based on this principle, the Arabic Language Education study program lecturer at IAIN Palangka Raya started learning maharah kalam by inviting students to review videos as a pilot, to be imitated and practiced. The purpose of this study is to describe the learning process of Mahārah Kalam using social cognitive theory. Using descriptive qualitative methods, research data is generated through the process of observation, interviews and documentation. The results showed that there were four basic activities of learning maharah kalam using social cognitive theory. First, observing the pronunciation of a conversational sentence from a learning video. Second, remembering the pronunciation of the sentence either in the form of vocabulary or the question word used. Third, replicating pronunciation by imitating conversational sentences according to the learning video. Fourth, showing abilities by exploring conversations, as well as the pronunciation learned

The issues of long-lasting violations of physical and mental health among employees of Children’s City Outpatient’s Clinic №133 of Moscow City Health Department after COVID-19, as well as they effect on work quality and efficacy, and in some cases loss of any interest to work got us thinking about the features of post-COVID-19 syndrome and and forced us to analyze the prevalence and duration of various symptoms in employees. The protocol for this observational study was approved by the Moscow City Independent Ethics Committee. Developed questionnaires with questions both on the course of COVID-19 and on the postcovid period have fully revealed the picture of psychological, cognitive and asthenovegetative disorders in employees. Healthcare professionals of our clinic were interested in studying this issue as many symptoms of the disease have significantly affected the working capacity of several people. The study involved 68 volunteers. Interesting data and correlations were obtained and they have confirmed the fact of cognitive and memory decline in some employees of Children’s City Outpatient’s Clinic №133 who underwent COVID-19 and the effect of these disorders on working capacity. Study results have shown that 47.5% of doctors and 50% of nurses feel disability of varying degrees after COVID-19. The major task of the head of the facility in such situation is to implement long, comprehensive and effective rehabilitation for employees in order to maintain the capacity of medical workers.

Authors: Vashakmadze Nato D. , Kostik Mikhail M. , Zhurkova Nataliya V. , Buchinskaia Nataliya V. , Zakharova Ekaterina Yu. , Soloshenko Margarita A.
Published: December 2021

Background. Mucopolysaccharidosis type I is disease from the group of lysosomal storage disease developing due to mutations in the IDUA gene. It leads to the accumulation of glycosaminoglycans (GAGs) in organs and tissues. Joints damage in this disease is systemic and progressive.

Objective. The aim of the study. Nowadays, relevant issue is to investigate the effects of various types of pathogenetic therapy on the state of the osteoarticular system in patients with severe and mild phenotypes of MPS I to prevent further progression of joint pathology.

Methods. The study included 46 patients diagnosed with “mucopolysaccharidosis type I”. 35 children had severe phenotype (Hurler syndrome) and 11 — with mild phenotypes (Hurler-Scheie and Scheie syndromes). The onset age of clinical manifestations in osteoarticular system, the state of large and small joints, and the presence of cervical stenosis according to the therapy were evaluated in these patients.

Results. The osteoarticular system pathology can be usually revealed in all patients with MPS I, in both mild and severe phenotypes. The contractures of shoulder, ulnar, wrist, and small hand joints have been revealed in most patients with Hurler syndrome, regardless of the administered therapy. Hip joints pathology was observed in children who was administered with: enzyme replacement therapy (ERT) — in 46.7% of cases, hematopoietic stem cell transplantation (HSCT) in combination with ERT — in 34.4% of cases. Patients with Hurler syndrome administered with HSCT in combination with ERT had cervical stenosis statistically significantly more rarely (p = 0.018) compared to patients treated with ERT only. Patients with Hurler syndrome who were on ERT had statistically significantly lower growth rates than patients after HSCT in combination with ERT. Lesions in ulnar, wrist, knee and small hand joints were the most common in children with mild phenotypes (in 90% of cases).

Conclusion. Combined therapy (HSCT and ERT) in patients with Hurler syndrome reduces severe manifestations in osteoarticular system, including children with a pathogenic nucleotide variant c.208C>T in a homozygous state.
The small bowel microbiome changes significantly with age and aspects of the ageing process
Authors: Leite Gabriela , Pimentel Mark , Barlow Gillian M. , Mathur Ruchi
Published: December 2021

Gut microbiome changes have been associated with human ageing and implicated in age-related diseases including Alzheimer’s disease and Parkinson’s disease. However, studies to date have used stool samples, which do not represent the entire gut. Although more challenging to access, the small intestine plays critical roles in host metabolism and immune function. In this paper (Leite et al. (2021), Cell Reports, doi: 10.1016/j.celrep.2021.109765), we demonstrate significant differences in the small intestinal microbiome in older subjects, using duodenal aspirates from 251 subjects aged 18-80 years. Differences included significantly decreased microbial diversity in older subjects, driven by increased relative abundance of phylum Proteobacteria, particularly family Enterobacteriaceae and coliform genera Escherichia and Klebsiella. Moreover, while this decreased diversity was associated with the ‘ageing process’ (comprising chronologic age, number of medications, and number of concomitant diseases), changes in certain taxa were found to be associated with number of medications alone (Klebsiella), number of diseases alone (Clostridium, Bilophila), or chronologic age alone (Escherichia, Lactobacillus, Enterococcus). Lastly, many taxa associated with increasing chronologic age were anaerobes. These changes may contribute to changes in human health that occur during the ageing process.
Laughter as a Semiotic Problem
Authors: Vershyna V. A. , Mykhailiuk O. V.
Published: December 2021

Purpose. The article is aimed to substantiate the view on the phenomenon of laughter as a subject of semiotic analysis, which leads to the following tasks: to reveal the possibilities of semiotics application in the study of laughter nature; to analyze the phenomenon of laughter as a cultural and natural phenomenon, as a sign and as an attribute; to consider the place of laughter in culture, which is understood as a sign system. Theoretical basis. The semiotic approach proceeds from the fact that human lives in the world of signs, all the surrounding reality can be interpreted as a sign system. The basic concept of semiotics is the concept of a sign. The theoretical basis of the article is understanding the culture as a sign-symbolic system. Laughter is considered as a phenomenon ontologically rooted in human culture. At the same time, laughter is on the edge of culture. The research is based on the work of semiotic authors, cultural researchers, and the researchers of laughter. Originality. The originality lies in the application of the semiotic method to the research of laughter phenomenon, consideration of the dialectics of natural and cultural, signedness and non-signedness, manifested in the phenomenon of laughter. Conclusions. Laughter is considered as a psychophysiological phenomenon (attribute) and as a cultural phenomenon (sign). Laughter acts as an emotional manifestation, a physiological reaction, but socially and culturally mediated. In any case, laughter indicates an emotional or cognitive state of a human. Laughter acts as a process and result of the interpretation of a sign, a reaction to a sign. Laughter is a form and a means of communication. Being a natural phenomenon, in the process of social evolution, laughter acquires signedness, is integrated by culture as a sign system, and, at the same time, maintains a connection with nature. Thus, laughter occupies an ambivalent position between nature and culture. In the phenomenon of laughter, the dual state of human is revealed. In laughter, boundaries are blurred, the unity and opposition of natural and cultural, biological and social, soul and body, thought and feeling, sign and attribute are manifested.

An adaptive approach to the calculation of the required power of the 1st and 2nd brake positions on the descent part of the sorting slides is proposed. The condition of technological reliability and "survivability" of the system of control of speeds of movement of couplings at rolling down from a sorting hill is checked taking into account action of probabilistic factors. The economic effect of reducing the need for car decelerators for the braking positions of the slides, as well as energy efficiency of sorting complexes. Practical value. The obtained important scientific and practical results to substantiate the reduction of energy consumption and increase the energy efficiency of sorting stations can be used to develop new projects and to survey the parameters of existing sorting complexes, including non-mechanized slides.
OPTIMIZATION OF CUT BRAKING MODES ON THE GRAVITY HUMP
Authors: DOROSH A.
Published: December 2021

Purpose. At the stage of development of modern information systems for controlling the process of breaking up trains on the humps, the main task is to determine such conditions for cuts' rolling, under which the established safety requirements for breaking up, as well as the requirements for the safety of wagons and cargo in them, are fulfilled. The determination of such rolling modes is undoubtedly a rather complex optimization problem, the solution of which is being addressed by a large number of scientists. In this regard, it can be considered that this problem remains relevant, therefore, the purpose of this research work is to determine such modes of braking of cuts of the train, which ensure their reliable separation when rolling from the top of the hill to the sorting tracks. Methodology. To carry out research on the process of dismantling trains on the hump, the method of simulation was used, and to search for the braking modes of the cuts of the calculation group, the Box complex method was used. Findings. The conditions for separating cuts of the calculated group of the train were investigated, and an iterative procedure was developed to optimize the braking modes of all the cuts of the train, which makes it possible to ensure the maximum value of the minimum interval in the calculated group. In this case, the specified procedure takes into account the intervals between the cuts, both on the arrows and on the retarders of the brake positions of the downhill part of the hill. Originality. It has been established in the work that when determining the modes of braking the cuts of the train, it is necessary to take into account the possible separation of the cuts on all elements of the downhill part of the hill - arrows and retarders. The problem of finding the optimal braking modes for all cuts of the train has been formalized and solved, which, in turn, allow providing reliable conditions for separating adjacent cuts at the turnouts and brake positions of the downhill part of the hill.  Practical value. The developed method can be used in the study of the sorting process, as well as in the automation systems for disbanding trains on the hump when determining the braking modes of the cuts.

SCIENTIFIC AND EDUCATIONAL ACTIVITY OF LIBRARIES AS A CRITERION OF LIBRARY REFORM
Authors: FIHEL Olena M.
Published: December 2021

Objective. The article examines the legislation of Ukraine in the framework of library reform. It is noted that in the presence of all changes and additions, the wording of the Law of Ukraine "On Libraries and Library Affairs" of 2021 regulates the activities of mostly public libraries. The peculiarities of the activity of libraries of higher educational institutions (HEI) are not reflected in the law. Methods. The methodological basis of the study were: general methods of thinking; general scientific and interdisciplinary methods. We can also distinguish: analysis and synthesis, abstraction, formalization and dialectical, as a general scientific method of cognition. Results. An example of a legal conflict regarding the legitimacy to use the status of a research and educational worker by the director of a University library is analyzed in detail. The study proves that libraries of higher education institutions are not obliged to conduct research and educational activities. However, in the absence of scientific lectures, workshops, and research, the library is reduced to the level of a subdivision of the HEI, whose activities are aimed only at providing information on scientific and educational activities of teachers and students. Conclusions. On the example of the Scientific Library of Ivan Franko National University of Lviv, known in Ukraine and abroad for its scientific lectures, art projects, research and explorations, the relevance and importance of conducting scientific and educational activities by Scientific Libraries of the HEI is shown.
ON THE FULL-FLEDGED MISSION STATEMENT OF THE UNIVERSITY SCIENTIFIC LIBRARY
Authors: LAZAREV Vladimir S. , YURIK Inna V.
Published: December 2021

The mission statement of an organization compiled in accordance with the definition of the term “mission” of the dictionary of the ISO 9000 quality management systems standard cannot be recognized as an effective management tool, since the ISO requirements for this document are too generic and vague. The objectives of this work were to clarify the functions of the mission statement of the university library as a management document, to develop a definition of the mission statement, consisting mainly of a list of its functions, and to develop a full-fledged mission statement of the Scientific Library of the Belarusian National Technical University based on the developed functional definition. Accordingly, the methods of work were the retrieval and interpretation of relevant scientific literature and the synthesis of data obtained from it for the development of new documents, viz. the definition of the mission statement and the mission statement of our library based on it. As a result, the intended functional definition of a university library mission statement as a full-fledged effective management document has been given and the mission statement of the Scientific Library of the Belarusian National Technical University has been crafted. The aspects of improving the efficiency of the library after the adoption of the new mission statement are briefly discussed.

Objective. This exploratory literature review seeks to identify both emergent consensus areas and research gaps in recent scholarly literature on Open Educational Resources (OERs). Despite the perception of OERs as universally available, these involve persistent barriers. The presence of institutional policies, adequate incentives and support frameworks for the use and sharing of OERs as well as raising awareness about their availability is likely to be critical for their successful deployment. Methods. This study made use of the case study method to arrive at its conclusions. As part of this, secondary data were collected from relevant article searches conducted in Google Scholar and at the Harvard Open Access Tagging Project website. Only papers published in the last five years, e.g., in the years 2016-2021, were taken into consideration. Given that this study has applied the methodology of qualitative comparison and case study construction, this limits the validity of its conclusions to the settings from which the original primary findings were obtained or for which OER recommendations were produced. Results. As part of this research, 16 scholarly articles and research reports were identified as being of relevance for this study. The research questions this study has sought to answer are as follows: How OERs have developed in recent years? What was the impact of the pandemic period on OER use? What are the key barriers for OER deployment? What are the facilitating factors for OER implementation at libraries, colleges and universities? What are the effects of OERs? Conclusions. Recent reports indicate that the pandemic period has both increased the awareness of OERs among education institutions and provided an impetus for capacity building efforts in this domain. Yet, OER effectiveness continues to be under-researched, despite a tentative consensus in scholarly literature concerning the critical role for OER efficacy of institutional support and collaboration frameworks.
Oxidative destruction of anionite AV-17×8 using the Fenton reaction
Authors: Kozlova M. M. , Markov V. F. , Maskaeva L. N.
Published: December 2021

The kinetic studies of AV-17×8 strongly basic anionite’s oxidative destruction using the Fenton reaction have been carried out. The effect of the process’s temperature and the concentration of catalysts of iron(II) sulfate or copper(II) sulfate on the oxidation of anion-exchange resin with hydrogen peroxide is estimated. With an increase in temperature in the range of 323–348 K, a regular increase in the effective rate constant of oxidative anionite destruction is observed when using iron(II) sulfate by 1.5 times, and when using copper(II) sulfate – by 22 times. It was found that the obtained values of the activation energy of the anion exchanger’s oxidation with the addition of copper(II) sulfate are 124.3–115.7 kJ/mol and are characteristic of the process proceeding in the kinetic region. The nature of the change in the surface morphology of the anionite granules in the process of oxidative decomposition has been revealed.

Funcionamiento familiar y adicción a redes sociales en estudiantes del nivel secundario
Authors: Lachuma Huansi Ursula Rosali
Published: December 2021

La presente investigación[1] tuvo como objetivo estudiar la asociación que existe entre funcionamiento familiar y adicción a redes sociales en estudiantes del nivel secundario de una institución educativa pública de Lima Este. Es de diseño no experimental, de corte transversal y de alcance correlacional. La muestra estuvo conformada por 603 estudiantes, de entre 12 a 18 años de edad. Los resultados de acuerdo a la muestra de investigación analizada, revela que existe una asociación altamente significativa entre funcionamiento familiar y adicción a redes sociales. Asimismo, en relación a las dimensiones del funcionamiento familiar, se encontró asociación altamente significativa entre cohesión familiar y adicción a redes sociales (X2 = 33, 236; p = ,000). De la misma forma, se halló asociación altamente significativa entre adaptabilidad familiar y adicción a redes sociales (X2 = 40, 318; p = ,000). Cabe destacar, que en esta investigación los adolescentes con familias con un nivel de cohesión y adaptabilidad alto, mostraron menor riesgo de presentar una adicción a redes sociales.

Creencias y prácticas de docentes universitarios respecto a la integración de tecnología digital para el desarrollo de competencias genéricas
Authors: Vera Fernando , García-Martínez Salvador
Published: December 2021

Este artículo de investigación pretende indagar en las creencias y prácticas del profesorado en torno a la integración de tecnología digital para el desarrollo de competencias genéricas en estudiantes de grado universitario, en el contexto de un proyecto de innovación curricular, bajo el modelo de aula inversa, en una universidad privada chilena. Para ello se optó por un enfoque cualitativo y etnografía virtual, analizándose la narrativa de 45 docentes en los foros registrados en un entorno virtual. Los resultados muestran que la mayoría de docentes utiliza presentaciones PowerPoint y el correo electrónico, como recursos tecnológicos en su praxis (84,44 % y 77,77 %, respectivamente). En cuanto al estilo de enseñanza, sigue predominando la clase expositiva. De esta investigación, se concluye que existe una relación directa entre las creencias docentes y la integración de tecnología digital en el currículo educativo.
Videojuegos y preadolescencia. Uso, hábitos e implicaciones socioeducativas en función del género

Los videojuegos constituyen en la actualidad una forma de entretenimiento muy extendida entre los jóvenes preadolescentes, pero también pueden convertirse en herramientas poderosas para la gamificación en las aulas y para la mejora de los procesos de enseñanza/aprendizaje. Además, facilitan el aprendizaje en diversos ámbitos del conocimiento y benefician el desarrollo de habilidades múltiples desde lo lúdico y lo creativo, pero también pueden provocar efectos negativos como adicciones, sedentarismo, disminución del rendimiento académico o problemas de sociabilidad. El objetivo del artículo de investigación es conocer los hábitos de consumo de videojuegos en la preadolescencia y sus implicaciones socioeducativas, en función del género de los participantes. La muestra está compuesta por 825 estudiantes de diversos centros educativos públicos de Andalucía (España), con edades comprendidas entre los 9 y 14 años. La investigación se desarrolla desde un enfoque metodológico cuantitativo, descriptivo, ex post facto, transversal y correlacional, utilizando el instrumento “Cuestionario sobre hábitos de consumo de los videojuegos” (López, 2012) para la recolección de información. Los resultados indican una clara diferenciación en las respuestas emitidas en función del género, indicando que los chicos se interesan más por los videojuegos, conocen un mayor número de ellos y los usan con mayor frecuencia que las chicas. Además, son ellos quienes demuestran tener una actitud más competitiva cuando los juegan.

El crecimiento en el uso de las tecnologías ha marcado una evolución evidente en los varios escenarios de la sociedad, y la educación es uno de los más impactados. Gracias a la incursión de la tecnología se ha propuesto el uso de herramientas como estrategias de enseñanza/aprendizaje, una de estas corresponde a los videojuegos que se han posicionado como un ámbito de notable y de creciente interés investigativo. El propósito de este artículo es realizar una revisión bibliométrica de los artículos científicos asociados a la temática videojuegos/educación. Para esta revisión se utilizó la base de datos Scopus®, con una ventana de análisis entre 2010 y 2020. Se procedió a realizar un análisis descriptivo para determinar las tendencias temáticas, los retos y desafíos principales en el área de los videojuegos; además, se miden los niveles de productividad, cantidad y calidad de los artículos. Los resultados muestran que la mayoría de los artículos se encuentran afiliados a instituciones ubicadas en España, Países Bajos y ee. uu.; que se presenta un creciente interés en el uso de las tic y los videojuegos en el marco de la pandemia ocasionada por el nuevo coronavirus (covid-19); que la mayoría de los manuscritos son de carácter reflexivo, pocos de ellos con propuestas efectivas o aplicadas.
