Consulta Araucanía: el uso oportunista de los mecanismos de democracia directa
Authors: Corvalan Alejandro , Durán Micco Elisa
Published: January 2023

Los mecanismos de democracia directa han aumentado su presencia en todo el mundo. Junto a los beneficios que conlleva la participación ciudadana,  estos mecanismos han reabierto la posibilidad de usar elecciones con propósitos movilizadores. Este artículo revisa el uso oportunista de la Consulta Araucanía, llevada a cabo en el sur de Chile el año 2021. Esta consulta ciudadana preguntó acerca de una posible extensión de la militarización en el contexto del conflicto entre el Estado chileno y el pueblo mapuche. A partir del análisis estadístico, nuestro trabajo muestra que la consulta no representó las preferencias de la región, sino que movilizó a una parte de ella en función de un objetivo particular. Sus resultados, no obstante, fueron interpretados desde la retórica de la representación con fines políticos.
Policía militarizada en Chile: claves para comprender la violencia policial estatal en la relación al conflicto mapuche
Authors: Luneke Reyes Alejandra , Risør Helene , Martínez Wladimir
Published: January 2023

La decisión de militarizar la Araucanía chilena, esto es, llamar a las fuerzas armadas para el control policial en la zona, ha producido un amplio debate nacional y un escalamiento de la violencia en la zona. Y es que, como muestran distintos estudios, la explicación del llamado «conflicto mapuche» y de la violencia (estatal y aquella ejercida por grupos radicalizados) se ha centrado en el déficit político que ha tenido la solución al problema versus la criminalización de la respuesta por parte del Estado chileno. Una arista poco problematizada en este debate refiere a la estructura institucional y el carácter militar de Carabineros. En este artículo planteamos que la labor policial descansa sobre una tradición militarizada en la institución y esta herencia dificulta una relación protectora con la ciudadanía y también la solución al conflicto desde una perspectiva intercultural.
La dedicatoria a la Victoria de la sacerdotisa Vibia Modesta: una nueva propuesta de lectura ¿Una inscripción restituida?
Authors: Sabaté Morales Albert
Published: January 2023

Ofrecemos en el presente trabajo una nueva propuesta de lectura y edición para la inscripción italicense promovida por la flamínica Modesta. Recogemos las reflexiones concernientes a este epígrafe y aportamos nuevos argumentos con relación al significado semántico, contexto y datación de la pieza, con tal de generar nuevo conocimiento para actualizar el debate sobre algunas de las problemáticas que han surgido en los análisis de este texto lapídeo. Asimismo, analizamos la fenomenología con la que se relaciona el acto votivo: el protagonismo público de las sacerdotisas; la religión de las matronae; la movilidad geográfica de las mujeres aristócratas; la orientalización religiosa del Occidente latino. Presentamos también la hipótesis según la cual consideramos, a tenor de la información reunida, que la inscripción podría tratarse de una restitución realizada tras la afectación de la pieza original debido al terreno inestable sobre el cual se asentaba la colonia, cosa que explicaría las llamativas peculiaridades del texto.

El papel de la protección virreinal en Hispanoamérica para los letrados: propuesta para una nueva valoración (1690-1705)
Authors: Laske Trilce
Published: January 2023

Este artículo trata de la protección de los letrados en las Indias por parte de los virreyes a finales del siglo xvii. Pretende discutir la lectura historiográfica clásica que atribuye a los virreyes indianos un poder de protección menor respecto a la gente de saber. Por ello, recurre a dos figuras destacadas, procedentes tanto de Nueva España como de Perú, cuyas trayectorias fueron afectadas favorablemente por su cercanía y trato con dos virreyes.
Haberes militares: pago por deudas de guerra en la independencia de Venezuela, siglo XIX
Authors: Gonzalez Segovia Armando Jose , Chirinos José Daniel
Published: January 2023

Los haberes militares es un tema que ha sido referido en diversos contextos de la historiografía venezolana. La función del haber militar fue saldar la deuda del Estado nacional con los soldados y la oficialidad por servicios de guerra. Sin embargo, conforman un corpus teórico repetido, superficial y fraccionado. La idea de este texto es realizar una síntesis que permita abordar las diversas facetas de esta institución gubernativa para proponer una perspectiva de conjunto y amplia sobre el tema, en sus inicios como república de Colombia, y una vez desintegrada esta como Venezuela, desde la perspectiva que sirvió para el incentivo a la alta oficialidad y las fuerzas extranjeras a la guerra, a través del pago con bienes muebles e inmuebles y efectivo provenientes de bienes secuestrados como de los propios de la naciente república.

Sound Art and the Ecosophical Object: Some Aesthetico-Ontological Remarks on Machinic Productivity
Authors: Rodríguez-Mouriño Matías
Published: January 2023

When confronted with the problem of chaos and meaning in the context of the production of subjectivity, sound art emerges time and again as a privileged space for the rearrangement and production of new subjective consistencies. Faced with the processes of increasing subjective homogenization of late capitalism, the sonic imagination, in the centre of an ontological tension between the dissolution of meaning and its structural and phantasmatic redundancy, allows us to carry on “turning over the ground”. We have thus tried to explore sound art as collective enunciation, as a form of excess that goes well beyond the human realm and into the machinic plane of consistency, and we have done this through the prism of a-signifying semiotics. The conclusion we have reached is that of the need for a non-humanist, trans-species, machinic comprehension of sound art and its collective assemblage.
Subversiones sexoafectivas a través de lo grotesco en “La región Salvaje” de Amat Escalante
Authors: Alarcón Zayas Violeta
Published: January 2023

El presente artículo supone una aproximación a lo “grotesco” como dispositivo subversivo y crítico en la película mexicana La región salvaje (Escalante, 2016).  El concepto de grotesco, resulta de gran interés, pese a haber sido escasamente estudiado en general y aún menos en el cine (Connelly, 2015). Lo grotesco resulta un vehículo propicio para la crítica sociopolítica y la reflexión ética al diluir la demarcación tajante entre las antinomias, y desenmascarar, desde lo excluido, lo oprimido y/o censurado las realidades que subyacen a los esquemas de pensamiento y conducta hegemónicos, respondiendo a “los intereses fundamentales del debate humanista actual, que incluyen las representaciones de raza y género, la abyección y el otro, globalización y apropiación” (Connelly, 2017: 44).

Procederemos mediante un análisis discursivo del funcionamiento de lo grotesco, en concreto de lo traumático monstruoso, como dispositivo crítico de los modelos hegemónicos de sexualidad, así como para cuestionar los roles de género heteronormativos. Por tanto, aplicando este concepto, analizaremos cómo lo monstruoso desenmascara a nivel estético-discursivo, la opresión sexual y de género que sufren las mujeres en el México actual.

En el análisis se comprueba cómo lo grotesco funciona como un dispositivo rizomático (Guattari, Deleuze, 1980) en tanto que lo grotesco en sí, no es una esencia, es un hacer, una relación dinámica, un desequilibrio y desestabilización que crea un significado (Connelly, 2015). Es decir, lo metamórfico, lo intersticial, aquello que se escurre y escapa de las categorías, funciona en el movimiento, en las relaciones, en el proceso mismo de mutación.

The experience of noise in communication-intense workplaces: A qualitative study
Authors: Gyllensten Kristina , Fredriksson Sofie , Widen Stephen , Persson Waye Kerstin
Published: January 2023

Objective

The aim of the study was to explore and describe how workers in communication-intense workplaces in health care and preschools experience the sound environment. The dependence on vocal communication and social interaction poses a challenge using hearing protection in these working environments.

Method

A qualitative method was used, more specifically inductive thematic analysis was used, as this approach was deemed suitable to explore the staff’s experiences of the sound environment. Data were collected by interviews and to increase trustworthiness, several researchers were involved in the data collection and analysis.

Study sample

Workers from two preschools, one obstetrics ward and one intensive care unit took part in the study.

Results

Four main themes emerged from the thematic analysis: A challenging and harmful sound environment; Health-related effects of a challenging and harmful sound environment; A good sound environment is not prioritised; and Resourceful and motivated staff.

Conclusions

Workers in communication-intense workplaces in preschools, obstetrics care and intensive care reported that there was a relationship between the sound environment and negative health effects. In addition, the results suggests that the high motivation for change among staff should be utilised together with an increased prioritization from the management to reach innovative context specific improvements to the sound environment in communication intense working environments.
Validation of the efficacy of air purifiers using molecular techniques
Authors: Rausch Finja , Tanneberger Franziska , Abd El Wahed Ahmed , Truyen Uwe
Published: January 2023

The importance of air purifiers has increased in recent years, especially with the “coronavirus disease 2019” pandemic. The efficacy of air purifiers is usually determined under laboratory conditions before widespread application. The standard procedure for testing depends on virus cultivation and titration on cell culture. This, however, requires several days to deliver results. The aim of this study was to establish a rapid molecular assay which can differentiate between intact infectious and distorted non-infectious virus particles. Feline Coronavirus was selected as model for screening. First the samples were pretreated with enzymes (universal nuclease and RNase cocktail enzyme mixture) or viability dye (propidium monoazide) to eliminate any free nucleic acids. The ribonucleic acid (RNA) from intact virus was released via magnetic beads-based extraction, then the amount of the RNA was determined using real-time reverse transcription polymerase chain reaction (RT-PCR) or reverse transcription recombinase-aided amplification (RT-RAA). All results were compared to the infectivity assay based on the calculation of the 50% tissue culture infectious dose (TCID50). The nuclease has eliminated 100% of the free Feline Coronavirus RNA, while propidium monoazide underperformed (2.3-fold decrease in free RNA). Both RT-RAA and real-time RT-PCR produced similar results to the infectivity assay on cell culture with limit of detection of 102 TCID50/mL. Two UV-C air purifiers with prosperities of 100% inactivation of the viruses were used to validate the established procedure. Both real-time RT-PCR and RT-RAA were able to differentiate between intact virus particles and free RNA. To conclude, this study revealed a promising rapid method to validate the efficacy of air purifiers by combining enzymatic pretreatment and molecular assays.
‘Forbidden Dance’: A film treatment by Tonino Guerra
Authors: Hough-Dugdale Amy
Published: January 2023

Amidst a suffocating drought, a young, cloistered nun, Angela, experiences desires that draw her out of her convent to adventures, including a tarantella and collective sexual experience of dubious consent, that unsettle her and seem to reorient her relationship to Christ, direct her attention to the Madonna and ask the latter to end the drought in a prayer that is apparently answered.
Reflections on ‘Danza proibita’
Authors: Hough-Dugdale Amy
Published: January 2023

One of the first critical approaches to a text upon which Tonino Guerra was working until days before his death in 2012, this commentary addresses the poetic dimension of Guerra’s film treatment, his ethical and ecological concerns, the sacred role of rain and water, the importance of interconnectedness and (non-institutional) spirituality and a rape scene that raises significant issues in terms of gender and women’s agency.
Where art and cinema converge: An interview with Massimiliano Siccardi
Authors: Bellacosa Juliette
Published: January 2023

In the course of a one-hour interview that took place in July 2021, Italian multimedia artist Massimiliano Siccardi, the creative mind behind the 2021 Immersive Van Gogh exhibit, discusses the ideas behind the exhibit as well as his vision for the future of immersive art. The former dancer and choreographer explores the possibilities for immersive techniques to revolutionize the concept of spectatorship as a collaboration between artist and viewer. The driving force behind Siccardi’s work is a commitment to the notion that art needs to be experienced, though the nature of that experience remains highly subjective. His work at Carrières de Lumières, and in 2021 with Lighthouse Immersive, exploit the merger of sound and image to create innovative immersive experiences that are intended to inspire the viewer’s appreciation and heighten interest in the works of art at the heart of the exhibit.

Sexualized female confidence: A new gender display in over 50 years of Italian fashion advertisements
Authors: Panarese Paola
Published: January 2023

This article examines the evolution of female images in Vogue Italia’s fashion advertisements over more than five decades. The aims of the article were to reconstruct the evolution of female representations over time, to detect the persistence of gender displays in women’s portrayals and to ascertain the existence, in the 2000s, of the visual regime of confident appearing. To achieve these aims, a longitudinal quantitative and qualitative content analysis was carried out on 1963 ads and 2568 male and female models. The research found an evolution of women’s images over time, the decline of some traditional genderisms and a resexualization of the female portrayals in the 2000s, interlaced with the confident-appearing visual regime. What emerged was a new gender display – a sexualized confidence – that does not eliminate gender differences or their structure of power but concentrates them in portraits of assertive and narcissistic women.
Women scientists in Italian media in times of coronavirus: Between low recognition and success as experts
Authors: Capecchi Saveria
Published: January 2023

During the months of lockdown due to the COVID-19 pandemic, Italian media helped provide an unprecedented degree of exposure for women scientists. The essay highlights the results of a quantitative and qualitative study on the portrayal and self-portrayal of Italian women scientists based on the digital editions of eight daily national newspapers and ten talk shows on the main national television channels from February to May 2020. The aim of the study is to show if and how those women scientists were valued as ‘experts’ or, alternatively, discredited professionally. The picture that emerges is ambivalent: on the one hand, most journalists of both sexes minimize the role of women scientists, and on the other hand, their ability to appear as authoritative in science as their male colleagues makes us optimistic about the role they can hypothetically play in convincing the new generation of Italian women to study STEM subjects.
Radio programming by and for women in Italy in the 1970s: The case of Noi, voi, loro donna
Authors: Natale Anna Lucia
Published: January 2023

This article explores the medium of radio as a vehicle for female empowerment from a cultural-historical perspective. It focuses on programmes by and for women on Italian public radio in the 1970s, at the height of second-wave feminism. In keeping with a constructionist approach that enhances the innovative potential of media, and recognizing radio as a source for women’s history, the article aims to identify the ways and goals by which radio speaks about women and addresses women. Following a case study methodology that focuses on the programme Noi, voi, loro donna (‘We, you, they woman’) (1978–82, Radio Tre), the article highlights the radio’s commitment for women’s rights: it offered a space for women-led discussion on women’s issues; it spread knowledge, reflections and analyses about gender inequalities and feminism; and thereby it provided women with the cognitive tools to acquire self-awareness, become familiar with new ideas and behaviours and redefine their identities.
Italian cinema and media: Past and present, continuity and change, expectations for the future: Journal of Italian Cinema & Media Studies – Third International Conference, American University of Rome, 16–18 June 2022

Ethnic mobilities and representations in Rose-Marie on stage and screen
Authors: Everett William A.
Published: January 2023

This article interrogates representations of ethnicity in the long-lived musical play Rose-Marie from 1924, with music by Rudolf Friml and Herbert Stothart, book by Otto Harbach, and lyrics by Harbach and Oscar Hammerstein II, and its subsequent MGM film adaptations in 1936 and 1954. The story is set in Canada, and images of Indigenous people include white-created tropes of children of nature, vicious savages and drunkards. These views are manifested aurally through Indianist musical tropes of the time, and are especially evident in ‘Indian Love Call’ and ‘Totem-Tom-Tom’. Whiteness is performed opposite portrayals of Indigenous people that range from the ‘noble savage’ of the famous ‘Indian Love Call’ to Wanda, a First Nations woman characterized as violent and over-sexualized in the 1924 and 1954 versions. Friml’s multifarious score includes recognizable Indianist tropes of the time as well as quintessential operetta and musical comedy fare, thus musicalizing cultural differences through established Eurocentric means. In Rose-Marie, the title character’s mobile ethnicity shifts from being presumably French-born French Canadian in the original to English Canadian in the 1936 film (starring Jeanette MacDonald) and French Canadian in the 1954 version (starring Ann Blyth). Although Rose-Marie and Wanda behave in similar ways, Rose-Marie’s singing whiteness allows her to become a romantic lead, whereas Wanda, whose dance-dominated performance mode emphasizes a sensual physicality, is vilified because of her ethnic heritage.
Le seul, le vrai, le paradis: Cultural mobility and French musical films (1930–50)
Authors: Kollinger Franziska
Published: January 2023

Maurice Chevalier, Juliette Gréco, Yves Montand, Édith Piaf, Charles Trenet – all these names refer to the close connection between French chanson and French cinema of the first half of the twentieth century. This article examines two dimensions of cultural mobility that align through a differentiated understanding of the artistic liaison between the popular music genre of French chanson and French musical films during the first decades of cinematic sound. First, the significant role and excessive use of the chanson will be examined along the parameters of cultural integration, distribution and transfer, all of which are inseparably linked to questions of cultural and social identity in the French musical of the 1930s and 1940s. Second, the formation, establishment and impact of the singer–actor as a professional field within the cinematic sphere will be discussed from the perspectives of mobility and migration. The methodologically areal term ‘space’ will be enhanced by notions of social and cultural mobility recently brought forth by the cultural disciplines. This article helps to decipher aspects of cultural mobility in French musical films and sheds light on the potential for the cinema in increasing music’s mobility.

La Filosofía como disciplina "non grata" para la institución escolar moderna
Authors: Gili Gal Edgar
Published: January 2023

El propósito de este artículo es ofrecer una explicación, una entre otras igualmente posibles, que permita entender por qué la filosofía, ya sea en tanto que materia de enseñanza, ya sea en tanto que teoría de la educación, ha sido con frecuencia para la escuela moderna (s. XVI-XXI) una suerte de disciplina non grata, esto es, una disciplina que se acepta al tiempo que se margina.
Como se verá, una explicación de esta ambigüedad de la relación de la escuela con la filosofía puede encontrarse en un análisis genealógico de la escuela de corte foucaultiano, es decir, que puede encontrarse en un estudio de las condiciones históricas de emergencia y desarrollo de la escuela en la Modernidad. En concreto, se ha prestado atención a cuatro acontecimientos mayores: el gran cisma religioso del cristianismo, el nacimiento del capitalismo y de la razón de Estado, la irrupción del humanismo renacentista y el desarrollo de las ciencias humanas.
De este modo, se muestra que la escuela parece estar animada desde sus orígenes por intereses que son mayoritariamente contrarios o ajenos a la filosofía, pero se muestra asimismo que, aunque sea en menor medida, la escuela también parece estar animada desde el principio por intereses que son para la filosofía más bien favorables. Si todo esto fuera cierto, entonces se entendería por qué la filosofía ostenta un estatuto más bien ambiguo en su relación con la escuela.
A partir de aquí, es posible que también haya que considerar que una inserción plena de la filosofía en la escuela no puede lograrse solamente por medio de una reivindicación de sus bondades, sino que tal vez sea preciso que, además, se reclame que la escuela responda a intereses que sean para la filosofía más propicios.

integração da América Latina como instrumento para recuperação econômica pós-pandemia
Authors: Oliveira Alessandra Cavalcante de
Published: January 2023

A América Latina sofreu fortemente com os efeitos negativos gerados pelas medidas adotadas para evitar o alastramento do contágio da Covid-19.  Na região, observou-se a redução da produção, do comércio internacional, entre outras consequências que levaram à recessão econômica. Para reverter tal cenário, os governos adotaram diversas medidas econômicas anticíclicas. Entretanto, indaga-se: se os países se unissem para enfrentar a crise com a adoção de ações conjuntas seria possível acelerar o processo de recuperação econômica na região? Esse artigo procura mostrar que o aprofundamento da integração regional pode ser uma medida eficaz para acelerar o processo de recuperação da atividade econômica. Isso porque o comércio intrarregional tem um grande destaque para manufaturas, que garantem um maior efeito de transbordamento sobre a economia. Para a análise, parte-se de uma análise quantitativa de dados econômicos e qualitativa sobre cadeias globais de valor para compreender como a integração pode contribuir para a recuperação econômica. O artigo é apresentado em três partes. A primeira seção apresenta os efeitos provocados pela crise sanitária na economia. A segunda parte discute sobre os benefícios que a integração pode trazer. Na terceira seção, são mostradas as ações a serem implementadas para o aprofundamento da integração. O estudo revela a existência de obstáculos possíveis de serem superados desde que haja vontade política. Por esse motivo, mostra-se a urgência de os governos se mobilizem em prol de um projeto regional que poderá beneficiar toda a América Latina.

Published: January 2023

We studied the duration of hospitalization and clinical outcome of patients with an uncomplicated STEMI (ST-elevation myocardial infarction) treated with primary percutaneous coronary intervention (PCI) in New York State between 2007 and 2009. Among the 4,939 such patients, 1,818 were discharged after 2 nights, and 1,922 were discharged after 3 nights. There were no deaths on the day after discharge among patients discharged after 2 nights. There was also no significant difference in 30-day mortality or readmission between patients discharged after 2 and 3 nights. In conclusion, 24-hour mortality was very low in patients with an uncomplicated STEMI discharged after 2 nights in the hospital, based on physician judgment. Thirty-day mortality is also low and similar to that of patients discharged after 3 nights in the hospital.
PREDICTION OF TRACK STRUCTURE DEFECTS BY MACHINE LEARNING METHODS
Authors: Platonov E. N. , Prosvirin K. V.
Published: January 2023

This paper proposes methods of defect prediction for railroad track superstructure objects using machine learning methods. In the railroad sector, most maintenance work is performed on a schedule, which can lead to system failure between two adjacent checks. In recent years, much attention has been paid to new technologies and “smart” approaches based on machine learning techniques, to build a predictive maintenance system. The problem of defect detection from a machine learning perspective is a classification problem with two classes. The initial observation data for the state of the superstructure of the railway track of the problem are unbalanced. This is due to the fact that one of the classes, on the objects of which a track structure defect has been registered, occurs much less frequently. Therefore, when solving the problem, an important parameter is the binarization threshold for machine learning algorithm responses. Modern methods for solving classification problems for tabular data were used to solve the problem. In addition to classical machine learning methods, such as gradient boosting, recurrent neural networks of different architectures were used. The results suggest that a practical threshold has been reached for the accuracy of model predictions, taking into account the noisiness of the input data. The practical significance of this work is that the proposed set of methods can be considered as part of a track maintenance decision-making system. It can be easily adapted for online operation and integrated with an automated measuring system based on a track geometry “recording” car.
AGGREGATION OPERATORS VISUALIZATION USING 3D COGNITIVE GRAPHICS
Authors: Sakulin S. A.
Published: January 2023

To solve social dilemmas in multi-agent reinforcement learning it is necessary to formalize the corresponding reward functions in the form of aggregation operators. Such formalization encounters difficulties associated with the lack of an intuitive vision of the aggregation process among many practitioners. Various visualization methods have been proposed to overcome these difficulties. The proposed methods have disadvantages that prevent their wide application. The method proposed in the article differs from the existing ones by the use of a three-dimensional cognitive image which corresponds to a physical object with a well-developed intuitive spatial and physical perception. This method is based on the use of 3D cognitive graphics. The properties of the aggregation operator are directly related to the properties of the physical object which has a well-developed intuitive representation. An absolutely solid plane fixed on the support line by springs acts as such an object. The result of aggregation corresponds to the angle of deviation of the plane from the horizon. By placing loads that meet the criteria and indices of their interaction on this plane it is possible to simulate the corresponding operator including by means of virtual reality. A preliminary asessment of the formal properties of the proposed method was carried out in comparison with existing visualization methods using the example of the Choquet integral of the 2nd order. Based on the results of this assessment conclusions were drawn about the advantages of a three-dimensional balance model over existing visualization methods and the feasibility of continuing work in this direction.
AUTOMATION CHOICE OF THE SOLUTIONS WITH PRECEDENTS USING BASED ON THE ALTERNATIVES FROM PARETO SET
Authors: Kazakov P. V.
Published: January 2023

The paper introduces the approach to automation of Pareto set reduction and solutions selection using precedents. In multi-objective optimization process the problem to select Pareto-optimal solutions emerges very frequently. Such a choice is possible not based only on the expert’s preference scheme but with precedents using. They reflect the accumulated experience in decision making on the similar problems solving. The generating of these precedents based on the alternatives from Pareto set is suggested. The procedures for automation of the precedents base creating and precedents matching for new solutions analysis are offered also. In this approach the precedent is an aggregate of some obtained Pareto-optimal solution and their fitness rating for expert. Such fitness value may be assigned directly by him or determined by results of clusterization, so that the solutions from same cluster have been got the equal fitness values. Further the fitness value estimate of new solution of multi-objective optimization problem may be performed with machine learning methods using such as decision trees, artificial neural network without calling expert. The series of experiments for accuracy testing on fitness assessment of new solutions were conducted for a multi-objective optimization test problem. The high accuracy was achieved for a compact base of the precedents with a decision trees method using and neural networks using for relatively large base of the precedents were more effectively.

The article discusses modern approaches to modeling socio-economic systems and methods of modeling information flows that determine systems functioning in the information environment. Principles of modeling socio-economic systems are proposed based on considering the system as a fragment of the information network formed by a set of open interacting socio-economic systems. The properties of the socio-economic system are considered from the point of view of its inclusion in the network. The considered properties are associated not with the system name in the set, but with the functions that the system is endowed with in relation to other systems as elements of the network, which makes it possible to define such a network as a space. The concepts of a system neighborhood, which defines its near environment, and a contour as a chain of information flows, which determine the system inclusion in the information space, have been introduced. A model of digital information space is built as a system of neighborhoods that determines the topology in space. It is shown that the representation of the network as a topological space makes it possible to find for each socio-economic system such contours that determine the mission of the system in society. In this context, the task of management in the socio-economic system is formulated as maintaining its inclusion in these contours, which determines the place and importance of the system in meeting the needs of society, anticipating the emergence of new needs and inclusion in new contours to meet these needs.
SOFTWARE COMPLEX FOR THE ANALYSIS OF THE STOCHASTIC PROGRAMMING PROBLEMS WITH PROBABILITY CRITERION
Authors: Torishnyi R. O.
Published: January 2023

This paper describes the software complex for the construction of a smooth approximation of the probability function and its derivatives. The structural parts of the complex, its functionality and mathematical background are described. The software complex constructs an approximation of the probability that some loss function does not exceed a certain level of loss. The program supports lossfunctions defined in a LaTeX format and contains predefined standard functions, variables and mathematical signs. The software supports different variable types, such as constants, control variables, stochastic variables with known distribution and parameters and samples of stochastic variables with unknown distribution. The software complex supports a variety of predefined random distributions and allows to tune the result by setting other service parameters. The implemented approximation is based on the replacement of the Heaviside function inside the probability function expression with the sigmoid function. Next, the approximated probability function and its derivatives are represented as volume integrals. These integrals can be calculated numerically using the Monte-Carlo method. This approach provides a relatively quick and universal method of approximate calculation of the probability function and its derivatives. The software complex has a graphical user interface and produces a graphical representation of approximated functions along with their points data. The program also supports the construction of the surface approximations for the case of the loss function having two control variables. Obtained graphical and point data can be used in the solution of stochastic programming problems with probability criteria. Examples using the software complex as a tool for analyzing stochastic programming problems are given.

One of the risks of information security of companies is the risk of information leakage through the screen photography. Often this happens using a mobile device. In view of this, it is worth the task of automated detection of this fact of violation of the security protocol. Classically, the phone search method in the frame is to consistently study the entire frame area. However, the specifics of the phone search in this task lies in the partial overlap of the brush with a brush, which makes the phone to be small among other background objects in the frame. Therefore, a combined algorithm is proposed, combining both the hand detection method, and the method of finding the phone. Issues of using hand detection methods are given in the image, as well as methods for finding rectangular areas. Finding on the image of the hand allows you to narrow the search area of the phone. For this, the boundaries of the rectangular search area, the coordinates of which depend on the coordinates of the keypoints of the hand are determined. Further phone search is made only in this area. This allows to increase the accuracy of the detection of the phone in the frame. The article provides an assessment of the results of the proposed algorithm. To do this, a comparison of the accuracy and speed of the proposed combined algorithm with existing ones. The results of the comparison are reduced to the table. The assessment showed that the use of a combined algorithm allows to improve the accuracy of the detection of the phone with a small loss of speed of processing of the entire frame.

The article explores phenomenon of engagement as a socio-psychological category that determines physical, emotional and intellectual state of a person involved in any activity. Further, engagement is considered as one of the factors that significantly affects the effectiveness and success of a person's professional activity. Methods for assessing engagement, distinguished by the types of data collected and approaches for their collection, processing and interpretation in the context of engagement, are analyzed. Existing software tools for assessing engagement based on self-assessment and systems for automatic assessment of engagement based on computer vision and machine learning methods are described. The concept of software user engagement as a user's reaction to interaction with this software is considered. The possibilities of using the results of user engagement assessment to assess the activities of people directly related to the use of the software are shown. Various factors that determine the interaction of the user with the software and affect his engagement are analyzed. The possibilities of using user engagement to assess competitiveness, usability, popularity and the overall quality of the software itself with which the user interacts are considered. Approaches to using the results of the user engagement assessment for adapting the learning process in learning systems are considered. The method of combined online assessment of engagement is described, in which engagement is considered as an indirect assessment of the success of the user's learning process and the results of the analysis of engagement are used to adapt the learning process to this user. The results of the study are represented as a mental map with the categorization of the concept of engagement. Directions for further research are described related to the development of an intelligent support system for assessing user engagement, based on the analysis of observed heterogeneous data on the current state of the user and behavioral metrics collected in the process of user interaction with the software and a combination of methods for their processing.
MARKOV REGIME-SWITCHING MODEL DEVELOPMENT FOR NUMBER OF DEFAULTS OF INVESTMENT AND SPECULATIVE GRADE ANALYSIS
Authors: Glushenko A. A. , Kulikov A. V.
Published: January 2023

In this paper the Markov regime-switching model was constructed for the main classes of credit ratings – speculative and investment. Estimates of the model parameters were obtained based on statistics on credit ratings and the number of defaults from the annual reports of S&P Global. The VIX volatility index was taken into account for a more accurate prediction of the probability of default. A similar model was constructed for the average annual value of VIX. Also a combined regime-switching model was considered, taking into account both statistics on the number of defaults of the speculative and investment grade and statistics on the average annual value of the VIX index for the period from 1990 to 2019. 10 parameters were estimated using the maximum likelihood method: the probability of the onset of a crisis and the probability of overcoming it; the probability of default in a crisis and non-crisis year for counterparties of the investment and speculative rating classes; the mathematical expectation and standard deviation of the VIX value in a crisis and non-crisis year. Two-stage backtesting of these models was carried out based on the obtained values of the parameter estimates. The first step was to check if the number of defaults falls between the quantiles of a mixed distribution consisting of a mixture of two binomials for the number of defaults and a mixture of two Gaussians for the VIX value. The second step was to check whether the number of misses in the first step falls within the two-sided confidence intervals of the binomial distribution. Finally, the number of defaults in 2020 and 2021 was forecasted and a comparison was made of the forecast for 2020 with the real numbers of defaults from the S&P Global report 2020.
