The story behind the cinematic true crime documentary: working towards a typology

ABSTRACT Historically, documentaries have employed cinematic techniques, but since the 1990s there has been a pronounced application of such devices for theatrical appeal. This trend, amplified by digital streaming platforms, raises concerns about representations of reality. To understand the scope of such concerns, a key question arises: what constitutes some of these ‘cinematic’ techniques used within documentaries? Despite claims that appealing documentaries often employ Hollywood storytelling strategies, there is limited understanding of how the genre adopts specific devices for cinematic entertainment. This article examines true crime documentary The Imposter, analysing its use of cinematic screenwriting and story devices, specifically dramatic structure. An analytical model is synthesised through genre theory (thriller) with Lucy V. Hay's understanding of the Three-Act-Structure, underpinned by relevant literature. This examination reveals how the documentary employs ‘cinematic’ aesthetics and thriller conventions to engage audiences. Drawing on Murray Smith’s ‘Structure of Sympathy’, the article explores the filmmaker's application of these storytelling techniques, shedding light on their potential capacity to shape audience appraisal of real-world events and subjects in true crime documentaries. The analysis aims to identify and unpack these specific storytelling devices, contributing to a deeper understanding of the impact of cinematic techniques in nonfiction filmmaking for representing reality.

Investigating immersion and migration decisions for agent-based modelling: Acautionary tale.

Agent-based modelling provides an appealing methodological choice for simulating human behaviour and decisions. The currently dominant approaches based on static transition rates or unverified assumptions are restrictive, and could be enhanced with insights from cognitive experiments on actual decision making. Here, one common concern is that standard surveys or experiments may lack ecological validity, limiting the extent to which research findings can be generalised to real-life settings. For complex, highly emotive decision-making scenarios, such as those related to irregular migration, the typically used short, methodical survey questions may not appropriately map onto complex real-world decisions of interest. Immersive contexts may offer more accurate representations of reality, potentially enhancing the usefulness of experimental information in multi-disciplinary modelling endeavours. This preregistered study, aimed directly at examining the effect of immersion on risk-taking in the context of migration decisions, and indirectly at informing a multi-disciplinary construction of an agent-based model of migration, presents a choice-based interactive fiction game in which players make migration decisions to advance through a story. (N = 1000 Prolific users) took part in one of four experimental conditions, three involving different renditions of the game attempting to create immersion, with the last condition presenting the decisions in standard survey format. Although addressing the lack of ecological validity in survey data is important for improving agent-based modelling methodology, the experimental design used to tackle this issue, while responding directly to modelling needs, proved too complex. The created experimental conditions ended up too distinct from each other, involving stimuli that differed in quantity and content. This introduced several unintended and uncontrolled confounds, making it impossible to meaningfully interpret the results of this experiment on its own. Our results act as a cautionary tale for agent-based modellers, highlighting that the modelling needs should not override the principles of experimental design, and provide motivation for more rigorous research on this topic.

A novel device for electrocardiographic imaging

Abstract Background Electrocardiographic imaging (ECGi) is a non-invasive imaging tool that allows 3D visualization and characterization of the electrical activity of the heart from measurements on the body surface by solving the so called "inverse problem of electrocardiography". This method helps overcome the limitations of the conventional12-lead ECG in diagnosing and locating heart arrythmias. We developed a textile 34-electrode imageless device (with no need for MRI or CT-scan). Purpose We aim to evaluate the feasibility and safety of the use of a novel textile imageless 34-electrode device for recording ECGi for identification of electrical activity of the heart. Methods and results The performance of a prototype data acquisition system (DAS) was evaluated in 158 individuals. Tests were conducted in three hospitals. The mean age was 43.32 years old (±17.44); mean height 167.31cm (±18.33); mean weight 70kg (±15.68). Almost 88% of the patients were in sinus rhythm. The relative frequencies of the targeted pathologies are listed in Figure 1. The collection of cardiac signals and posterior representation in virtual reality of a stereoscopic, holographic 3D-360º map, was achieved in 100% of the patients. Figure 2 shows the textile hardware with the silver dry electrodes and a screenshot of the software with an example of a voltage map in a patient in sinus rhythm. There were no adverse effects reported. The DAS is composed of 34 electrodes, being their distribution representative of the electrical activity on the torso. Several studies have discussed the minimum number of electrodes on the torso of the patient required to characterize the heart potentials from the electrical potentials on the torso surface through the inverse problem (1,2). We highlight that the representativeness condition of the electrical activity on the torso is crucial to appropriately estimate cardiac activity with the minimum number of leads on the DAS. Conclusion The use of a novel textile imageless 34-electrode device for recording ECGi for identification of electrical activity of the heart is feasible and safe.Targeted rhythmHardware and software

Historical Architecture and BIM Modelling: Between Representation of Reality and Conceptual Abstraction

The essay aims to explore the applications of BIM to design regarding historic buildings, which will become mandatory in Italy from 2025 for public works above €1 million. Despite the advantages in coordinated data management and information sharing among the actors involved in contracts, problems related to the geometric representation and semantic definition of the virtual entities that populate the models have been recognized by the scientific community. Critical issues that have emerged from the study of significant experiences can be traced back to the difficulty of adapting tools designed for the projects of new buildings to the characteristics of the cultural heritage. In particular, the complexity of proposing congruent categorisations and parameterisations seems related to only partial correspondence between historical building components, IFC classes and BIM software categories. These limitations often lead to the identification of contingent solutions and expedients, which solve only the problems of geometric representation. In contrast, the ability to adequately share information stored in databases, interoperable through the IFC format, is conveyed by an appropriate semantic description. Formal representation in the BIM environment effectively refers to standardized industrial production, reproducibility of building elements and, more generally, to the goals of globalisation. Thus, the proposed reflections aim to encourage a conscious use of these tools and to outline implementation perspectives useful to bring the digital environment closer to the concrete reality of historical architecture, unique and irreproducible in origin and transformation, often realized through artisanal processes and anchored to specific contexts in multiple aspects.

ETHNOCULTURAL VOCABULARY AS A SOURCE OF ETHNICAL INFORMATION IN BRITISH LITERATURE

This article analyses S. Maugham’s and N. Hornby’s works, exploring how national values and ethno-culture are reflected in their writing. The study focuses on their works, one classic and the other modern, revealing the peculiarities of their styles, language. The article examines the role of phraseological units in creating character images in works of art, based on Hornby's modern English novel ‘About a boy’ and 'The Razor's Edge' by S. Maugham. Phraseology plays a crucial role in language as it helps to convey the author's true intentions. By updating the usual and occasional meanings in context, phraseological units allow readers to understand the depth and versatility of artistic images created by writers. The idiomatic and phraseological units employed by writers can be used to construct a cultural picture of nation and country. Therefore, studying the works of classic and modern writers is a significant objective in itself. The employed methods, namely comparative, cultural-historical and stylistic analysis of the collected data, contributed to the revelation of the principal approaches of the two writers in their representation of reality. The results of the study reflect the linguistic features of the prose of the two writers, including stylistic devices, fixed expressions and idioms. This enables a linguistic and literary analysis and interpretation of the British works, thus conferring practical significance upon the study. It is concluded that both writers use phrases related to their national mentality and historical periods.

Chronotopes of home and dislocation: recognising the lived experiences of refugees

ABSTRACT Forced migrants are often presented in public and private discourse from a reductive perspective focusing solely on their vulnerability and their status as refugees, without acknowledging other aspects of their identity and life history. This article investigates how refugee-background participants in qualitative research interviews drew on the chronotopes of home to construct a narrative of origin that foregrounded diverse aspects of their identity and emphasised their lived experiences in a fuller sense. In their narratives, participants contested representations of their home countries and of historical events, as well as representations of themselves, to challenge reductive identity constructions. Further, the narratives suggested that while widely known, mass-mediated chronotopes may assist in initial orientation to a location and event or time period, these generally provide a limited, and sometimes a highly contestable, representation of reality.

Refined one-dimensional modeling and experimental validation of scroll compressor with vapor injection for electric vehicles

Vapor injection technology represents a highly promising avenue for enhancing the efficiency of heat pump systems within electric vehicles, especially in challenging cold ambient conditions. Although a simplified isentropic process is commonly employed to assess the thermodynamic functioning of scroll compressors with vapor injection (SCVI), it diverges significantly from actual operational dynamics. This study introduces a sophisticated 1D mathematical model that incorporates key factors such as internal leakage and thermal losses, thereby providing a more accurate representation of SCVI's operational realities. The research includes comprehensive performance evaluations of a short wrap profile SCVI, with a specific focus on low-temperature ambient conditions, supported by rigorous experimental validation. Comparative analyses against non-injection scenarios reveal notable enhancements, including a maximum 17.2 % increase in mass flow, a 10.5 % rise in heating capacity, and a 2.15 % improvement in heating COP. Both the simplified isentropic process calculation model and the enhanced 1D mathematical model are utilized to analyze compressor operations. The integration of internal leakage and heat loss considerations significantly narrows the gap between calculated and experimental results for heating capacity and discharge temperature, reducing discrepancies from nearly 20 % to a mere 4 %. This refined mathematical model demonstrates a high level of alignment with experimental data, achieving an accuracy within 5 % when assessing the compressor's real-world operational dynamics.

Gobernanza ambiental, agua, saneamiento y residuos sólidos: ¿qué piensa al respecto la población costarricense?

[Objective] The objective of this study was to collect the perception of Costa Ricans on environmental issues in order to generate information to influence decision-makers. [Methodology] A descriptive-quantitative research was conducted from June 13th to 17th and June 20th, 22nd, and 23rd, 2022 through a telephone poll of 702 people, using a sampling of active cellphone banks in the country. [Results] Opinion polls provide elements of the population's sentiments and help measure actions developed in different areas; therefore, this study is relevant to show what the population thinks about environmental matters. For example, six out of ten people consider that the country's international prestige on environmental matters is an accurate representation of reality, but it is evident that 67.8% of the people polled think the government is not clear on environmental policies. However, the government must address 11 environmental issues as a priority. Furthermore, interviewees agree with the statements in the Escazú Agreement, as an instrument of international regulations regarding the right to citizen participation and information on environmental issues. On another issue, seven out of ten people indicate that the country's wastewater is dumped into the rivers, thus contaminating water sources. Regarding solid waste management, little progress is perceived regarding solutions to this problem. [Conclusions] Finally, there is evidence of knowledge about environmental issues and an expectation for the government to solve the problems identified as priorities.

Gender Aspect of Media Discourse in Socialist Yugoslavia – Representation of Gender in the Women's Magazine "Bazar"

The paper revises the gender aspect of media discourse in socialist Yugoslavia on the example of one of the oldest and most popular Yugoslav women's magazine "Bazar." An analysis of the textual and visual content of the 1973 edition (issues 208–233) reaffirmed the assumption that the mass media – including The Women's Press – actively participate in the construction and reproduction of both "femininity" and "masculinity", and in the depiction of desirable/expected gender relations in a certain socio-historical moment (Yugoslav socialism). In addition to the main female character – a beautiful, young, modern and well-groomed woman who is successful in all fields (at work, at home, as a wife, mother, sister, friend, worker...) – there is also an equally caring and dedicated husband and father, a modern man, successful in his field of expertise. In other words, of all the roles that Yugoslav society has assigned to women/men, the following seem to be dominant: She is primarily 1) a wife, mother and housewife, 2) a hard worker, and 3) a woman who is clearly positioned in the new consumer society, while He is 1) Pater Familias, 2) a successful businessman, and 3) a modern man who keeps up with the times. The research has shown that these (and such) "Bazar" images of a woman / man are highly harmonized with the official representation of gender in the socialist Yugoslav society – She is the embodiment of the socialist "super-woman", while He is depicted as part of the hegemonic model of masculinity. The female-male relationship is presented in the experimental media discourse in two ways. The first (socialist) model of gender polarity – the one that is in the central media plan / easily observable / clearly legible – is placed in the official narrative framework of socialism as an ideology that follows the principle of equality as the dominant matrix in social/gender/economic/family relations. In the second narrative plan, there is a traditional model of gender polarity, which is based on binary oppositions – weak-strong, gentle-rough, subordinate-dominant, dependent-independent, right-wrong – performed by the female-male couple. By analyzing the media discourse of the experimental socialist periodical, it has also been established that the narrative of one of the most popular Yugoslav women's magazines contains all three key terms (for gender reading or in the media text) – these are power, gender (in)equality and representation of meaning. Interpreting textual and visual content as a system of representation (and not presentation) of reality, it becomes obvious that despite the change in social paradigm in the years after World War II, the policy of gender representation in the context of power relations (man over woman) continued, which Yugoslav socialism – as a doctrine of equality – clearly could not (or did not want to) eradicate in practice.

Technoscientific speculations: the anti-mimeticism of Japanese science fiction in the literary context of the late Meiji period

This article proposes that Japanese science fiction emerged as an escape from the limits of the realistic representation of the world proposed by Naturalism. It reads three science fiction short stories published in the magazines Tanken sekai (World of Exploration) and Bōken sekai (World of Adventure) between 1907 and 1910 to discuss early science fiction in which authors utilised technoscientific discourse. Engaging in a set of textual practices centred on developments of modern science and technology, these authors developed one of science fiction’s distinctive features: anti-mimeticism, a literary mode focused on the depiction of anything that cannot happen in real life. This article focuses on the modalities by which these stories—Tenkūkaikatsu Dōjin’s ‘Gessekai shinkon ryokō’ (Lunar Honeymoon), Ishii Kendō’s ‘Gessekai dokuryoku tanken’ (Self-made Exploration to the Moon), and Hakui Michihito’s ‘Yukai to benri wo kiwametaru ōgon jidai no tokai seikatsu’ (The Extremely Amusing and Comfortable Golden Age of Urban Life) 1 —employ a rationalistic view of the phenomenal realm to generate fictional worlds that relinquish the dominance of a mimetic representation of reality. An analysis of early Japanese science fiction from the late Meiji period reveals two elements that eschewed the realistic literature such as Naturalism: objective narration and an anti-mimetic base for the fictional world.

Artistic Autoethnography in Human Resource Development: Deepening Empathy and Affective Understanding to Forward Diversity, Equity, Inclusion, and Social Justice in the Workplace

Artistic ethnography is growing in prevalence across the social sciences and has been used to explore daily lived experiences with marginalization powerfully. This approach, however, has received very little attention in Adult Education and HRD literature. Artistic approaches to autoethnography engage with aesthetics, feelings, and embodied experiences while pushing researchers to consider ways they can work outside of standard social scientific prose style writing and numerical abstraction when creating representations of lived reality. Artistic approaches to autoethnography can enhance all areas of HRD research and practice but hold salience for critical HRD, as its leading proponents have called for an emphasis on “relating,” engagement with the affective domain of workplace injustice, and “radical vulnerability” as we work to imagine and create more just organizations. The purpose of this article is to explore how artistic autoethnography can advance the critical work of HRD by carving out a nurturing space where those living with the daily discomfort of marginalization can finally share their feelings and explore insights that stretch beyond the limitations of standard academic prose.

Digital Media Audiences and Generations – Theories, Trends and Challenges

The digital age has brought several changes in the understanding of the former mass media and the way of distributing different media contents, but also in the ways of media audience involvement in mass communication processes. Due to the large amount of information and the channels through which it is disseminated and the increasingly fragmented media audiences, the influence of the media on contemporary democratic societies has changed significantly compared to the influence of the mass media in the 20th century. Differences in media representations of social reality, the dispersion of their authors, the number of publications and their reach, as well as the conditioned interpretations of media audiences, have led to the so-called post-truth media constructions of reality, also one of the key features of the 21st century. In this paper, the authors provide an overview of theories about media audiences and generations that have been developed within the communication sciences. They specifically focus on the contemporary trends that have affected the disappearance of the mass audience due to its intense fragmentation as a result of the technology change, and at the end of the paper, they highlight the social changes that arise as a result of the aforementioned processes.

Evaluation of precipitation products in a Brazilian watershed: Tocantins-Araguaia watershed case study

Precipitation plays a vital role in various fields, including hydroclimatic modeling, climate change studies, agricultural optimization, and water resources management. Precipitation data can be obtained through observational measurements using the rain gauge approach or as Gridded precipitation products (GPP) derived from satellites or atmospheric models. GPPs provide optimized global estimates of climate data without spatial or temporal gaps, making them a valuable solution for areas with sparse or nonexistent rain gauges. However, it is essential to assess their reliability and limitations across different time scales and regions before usage. This study aims to evaluate the accuracy of two specific GPP datasets, ERA5 and MERRA-2, in comparison with two observational datasets, focusing on the Tocantins-Araguaia watershed and Pará river estuary in Brazil. The results show that both GPPs, ERA5 and MERRA-2, captured the overall precipitation regime for the analyzed period. However, discrepancies emerged, particularly at the daily and annual scales, with better agreement observed at monthly and climatology scales when compared to observational datasets. ERA5 demonstrated a higher number of acceptable stations compared to MERRA-2. Although both reanalysis products showed good agreement in climatological analysis, a more detailed evaluation revealed shortcomings in simulating precipitation during the dry season. While GPPs offer consistent time series with higher temporal and spatial resolutions, the observational precipitation data is deemed the most suitable input for hydrological-hydrodynamic modeling in the Tocantins-Araguaia watershed. Its widespread coverage, numerous rain gauges, and accurate representation of reality make it an ideal choice for hydrological modeling in the region.

Self-assessment criteria as projected realities: a social cognitive study on student experience in postgraduate thesis writing

While research on postgraduate thesis writing has investigated how students cope with institutional assessment criteria, this study explores how students form their own criteria for self-assessment through the writing process, aiming to account for the development of their independent thinking in academic socialisation. Based on in-depth interviews with 10 Chinese master’s students, the study found that their self-assessment criteria not only represented solutions to problems identified by their supervisors and examiners, but also embodied aims established by students themselves. Those criteria were not fixed textual properties of a ‘good’ thesis, but were dynamic representations of textual and social realities constituting students’ lifeworlds. Viewed from this perspective, self-assessment is a situated process whereby students re-experience and re-interpret multiple sets of realities juxtaposed against their writing. Pedagogically, the study implies that postgraduate thesis supervision could facilitate the expansion of students’ self-assessment criteria to develop their capacity for making independent judgements.

A Comparative Study Between a Large Screen and an HMD Using Wind Representations in Virtual Reality.

In this article, we investigated the representation of wind in urban spaces through computational fluid dynamics simulations in virtual environments (VE). We compared wind perception (force and direction) as well as the sense of presence and embodiment in VE using different display technologies: head-mounted displays (HMD) and large screens, with or without an avatar. The tactile display was found to be most effective for detecting wind characteristics and enhancing presence and embodiment in virtual scenes, regardless of display type. Wind force and overall presence showed no significant differences between projection methods, but the perception of wind direction varied, which can be attributed to the head tracking of the HMD. In addition, gender differences emerged: females had a 7.42% higher presence on large screens, while males had a 23.13% higher presence with HMD (avatar present). These results highlight nuances in wind perception, the influence of technology, and gender differences in VE.

Formation of conceptual representations of reality on the basis of reflective practice (research experience)

Introduction. The transition from ordinary perceptions of reality to conceptualized ones is a significant problem of philosophical education. The aim of this article is to identify the ways of this transition in the course of doctoral students' work with modern philosophical literature, to substantiate ontological and epistemological principles of understanding reality, and to summarize modern approaches to solving this problem. Materials and Methods. On the basis of teaching practice, which goes back to Socrates' Maieutic method, the principle of “pro et contra”, and substantially determined by the discussions of realists and anti-realists about the nature of reality, the ways of strengthening the discipline of judgment, improving the reflexive culture, clarifying the bases of one's own ideas about the world and formalizing them in a thoughtful system of judgments are revealed. The method of research into the formation of conceptual representations of reality involves analyzing the ways of transition from unconsidered opinions through the recognition of their insufficiency and unsatisfactoriness to such knowledge, which Plato called ‘theory’ (θεωρία), i.e. rationally constructed principles of analytics. In this methodological approach (communicative-competence - in the modern formulation), the very sequence of cognitive acts is important: from ordinary ‘naïve’ perceptions - to a clear understanding of the complexity of the problem - then to the formation of questions in the audience that lead beyond a surface view of reality - and to the possible conceptual coherence and validity of perceptions of reality. Results. In the course of History and Philosophy of Science for doctoral students, the author proposed and justified the use of a three-level construct of moving from everyday representations of reality to conceptually meaningful ones. At the first level it was proposed to give an intuitive definition of the concept of ‘reality’; at the second level to analyze it, relying on sources from among those recommended by the lecturer or chosen independently, then briefly formulate the essence of realistic and anti-realistic approaches and identify the logic of one of them, and at the third level to move to the opposite position and present the relevant arguments. The author summarized the results of this procedure, which includes critical overcoming of ordinary statements about the nature of reality and dialogue between opposite conceptual solutions to the problem, and substantiated that such practice gives the effect of “awakened consciousness” and becomes the basis for readiness to conduct an internal dialogue on complex philosophical problems. Conclusions. The skills of reality analysis presented in the article develop and improve the reflexive practice of young researchers, clarify the basis of their own perceptions of the world, formalize them in a reasoned and critically elaborated system of judgments, and form their readiness to solve complex problems in science and philosophy.

REALISM AND COMPOSITIONAL REPRESENTATION OF REALITY : AN ANALYSIS OF THE MANIPURI DOCUMENTARY FILM “FRIED FISH CHICKEN SOUP AND A PREMIERE SHOW”

The debate around realism in documentary cinema has evolved significantly over the years reflecting broader shift in filmmaking techniques, compositional forms, audience expectation, cultural and political contexts. The realms of realism and compositional documentary have been in a constant state of flux, each genre pushing the boundaries of what is considered truth, authenticity, and artistic expression thereby blurring the lines between reality and fiction, and challenging the traditional notions of documentary filmmaking. Several Manipuri documentary films have made endeavors of recreating the reality through their representation on cinematic canvas. Depicting Manipur’s cinematic journey and its socio-political context in a compositional form, the documentary film “Fried Fish, Chicken Soup, and a Premier Show” (2012) relies heavily on editing with found footage and presents an even greater challenge with the inclusion of historical narratives. It intricately combines observational account of a film crew at work during the filming of the Manaobi MM’s Manipuri feature film “21st Century Gee Kunti” (2010) with intertitles, archival footage etc. to depict the history of Manipur. This paper explores the realism and compositional representation of reality in the film which skillfully blends diverse elements to document the trend of change and transformation within the cinematic landscape and the lived reality of Manipuri society in transition.

Balancing construction and operational carbon emissions: Evaluating neighbourhood renovation strategies

Compliance with the global decarbonisation commitments set out in Horizon 2050 undoubtedly involves optimising the conditions of the housing stock. In this respect, the massive energy renovation of obsolete housing blocks in southern EU countries holds the key for the achievement of such compliance.This research strives to demonstrate the suitability of intervention strategies at district scale. For this purpose, an innovative methodology that combines open data, Geographic Information Systems (GIS), Urban Energy Modelling (UBEM), and Life Cycle Assessment (LCA) is proposed and tested in a case study, whilst considering several renovation and new-building hypotheses.As an innovative approach, this study concurrently analyses greenhouse gas emissions arising from both use-related energy consumption (operational carbon footprint) and the construction process (embodied carbon footprint). This dual perspective provides added value to the results obtained, since it offers a more comprehensive representation of reality. Based on the results from the LCA and UBEM models, this study unveils the entire impact of residential energy use combined with either the carbon footprint of energy renovation or that of new buildings.The case study analysis reveals that total emissions, encompassing both embodied and operational aspects, are lower for retrofitting existing buildings when compared to new construction, up to Horizon 2050. Remarkably, this preference for renovation persists even as far as 2100. The study underscores the critical importance of upgrading the existing residential stock in order to achieve the ambitious goal of net-zero greenhouse gas emissions by 2050.

The influence of Survivor stories and a virtual reality representation of a residential school on reconciliation in Canada

Indigenous Peoples in Canada have endured many genocidal efforts, such as residential schools. Across the country, initiatives to promote critical historical education about residential schools are underway, ranging in duration, content, and immersion. In this study, we tested whether a promising high-immersion approach, a virtual reality residential school, could improve non-Indigenous participants' attitudes and feelings toward Indigenous people. We compared the effects of the virtual residential school to a transcript condition, in which participants read the transcripts of the narration that accompanied the virtual residential school, and an empty control condition. The study had three time points: Baseline (N = 241), intervention (N = 241), and follow-up (N = 132). Immediately following the intervention, what participants learned about the residential school, both through virtual reality and reading the transcripts, increased non-Indigenous participants' empathy, political solidarity, and outgroup warmth for Indigenous people, relative to the control. The virtual reality school, but not transcripts, also increased privity relative to the control. These effects decreased over time. In summary, though both written and virtual reality forms of critical historical education were effective in the short term, to maintain the long-term effects of critical historical education, ongoing or recurring education is likely necessary. These results extend the virtual reality literature to unstudied concepts (political solidarity, privity) and critical historical education literature to a new form of media (virtual reality). We discuss the findings in relation to literature on critical historical education and virtual reality as well as outline future directions.

МАТЕМАТИЧЕСКАЯ МОДЕЛЬ ОРГАНИЗАЦИИ ТЕХНИЧЕСКОГО СЕРВИСА

A wide range of agricultural machinery in need of high-quality maintenance throughout the entire operational period to ensure uninterrupted and efficient operation is one of the most important links in the agro-industrial complex. (Research purpose) The research purpose is developing a mathematical model showing the relationship between the conduct of maintenance activities and the unit of equipment of the agricultural fleet; within the framework of the obtained mathematical model, deriving a criterion assessment of the quantitative conduct of maintenance. (Materials and methods) Indicated that such estimates can be obtained by applying mathematical modeling. A mathematical model was constructed using a visual diagram reflecting the relationship between the machines of the agricultural park, types of maintenance, elements of set theory and mathematical analysis. We used the theory of sets, which allowed us to move from the units of equipment of the fleet of agricultural machines to an analytical representation of realities and derive a constant that gives an assessment of maintenance depending on the number of activities carried out during the time interval under consideration. (Results and discussion) It was noted that it is necessary to improve the quality of maintenance by improving the control of its implementation in real conditions. The novelty of this work consists in the originality of the obtained scheme linking the types of maintenance and the machines of the agricultural fleet, without being tied to the number of units of equipment; in the development of a mathematical model that allows, using theoretical calculations, contributing to improving the control of maintenance activities by obtaining a universal constant that quantifies for any type of equipment and maintenance. The theoretical results were tested using the Kirovets-739 tractor as an example. (Conclusions) We obtained a schematic representation of the relationship between the components of the machine and tractor fleet and a numerical estimate reflecting the number of completed scheduled maintenance steps during the time period under study when using mathematical methods in the organization and conduct of maintenance.
