SOCIO-PROFESSIONAL ADAPTATION OF REPRESENTATIVES OF DIFFERENT ETHNIC GROUPS: SOCIOLOGICAL ANALYSIS (ON THE EXAMPLE OF YOUNG TEACHERS IN AKTAU)
Authors:   Yessenov University, Kayupova Farida
Published: July 2022

Abstract. The problematic field of scientific work focuses on the professional adaptation of ethnic groups to socio-economic transformations in the educational environment and the integration of society. The research question within the framework of this work is to find out the influence of belonging to ethnic groups on the process of professional adaptation in the educational environment. To date, there are quite a lot of publications on the problem of social and professional adaptation. However, the issue of adaptation of ethnic groups has not been sufficiently developed. Psychological and pedagogical studies of this problem prevail, while sociological analysis makes it possible to reveal the essential features of these processes. This article was written on the basis of the results of a sociological study on the topic "Professional adaptation of young teachers." The purpose of this study was to study the characteristics of professional adaptation of representatives of various ethnic groups. In the research work, the concept of "adaptation" as a sociological category was considered and classical and modern approaches to understanding the essence and mechanisms of professional adaptation were analyzed. The study of scientific literature, revealing the topic of the study, allows us to distinguish several groups of works. The first group of works is devoted to the study of social adaptation, which analyzes various approaches: a systematic approach, an informational approach, a phenomenological theory, a normative approach (E. Durkheim, T. Parsons, etc.), an activity approach and an interpretive approach (M. Weber). The second group of works is devoted to the study of social and professional adaptation in line with the study of social and labor processes. These are the works of M. Weber, A.B. Georgievsky, T. Parsons, and others. Labor adaptation in the process of vocational training and formation was considered by N.V. Polyakova, K.U. Chembelenge and others. The third group of works is devoted to a comprehensive study of the essence, goals, content of pedagogical activity. For example, the works of S.V. Kondratieva, and others. In the second part of the work, the main factors influencing the social and professional adaptation of representatives of various ethnic groups were analyzed. A comparative analysis of sociological studies on socio-professional adaptation was also carried out. The final part of this article presents the results of the study, reflecting the features of the professional adaptation of representatives of various ethnic groups in the educational environment. Keywords: adaptation, young teachers, socio-economic development, factors of professional adaptation, Kazakhstan, ethnic groups, integration of Kazakhstani society, education, professional activity, interethnic interaction, motivation of professional activity.

Abstract. Kazakhstan is one of the world's largest oil-producing regions. Among the explored and exploited deposits, the largest are Tengiz, Zhanazhol, Karachaganak, Uzen, Zhetybay, Kalamkas, Kumkol and a number of others. The extracted oils are very diverse in terms of their physical and chemical properties, the content of asphaltenes, resins and paraffins. Many of them contain significant amounts of carbon dioxide, sulfur and its compounds. Kazakhstan has extensive experience in the development, development and operation of such deposits and monitoring the associated environmental impact. It can be generalized and used in the further development of the industry. The composition of the products of all deposits is unique and is the determining element in the choice of technological schemes for its collection and preparation. Methods for increasing the depth of preparation, efficiency and reliability have been sufficiently studied, but due to changing requirements and existing achievements, the arrangement work is always creative in nature, and the technological solutions made are becoming more perfect. Water is the only component of well production that has natural contact with oil and must be returned to the natural environment. Waste waters include formation waters that are separated at almost all stages of oil treatment, and flushing waters introduced for desalting and final dehydration of oil. Before injection into the absorbing reservoir, they must be cleaned. To prevent the formation of stable emulsions, solid deposits and suspensions, a system of preliminary water discharge at the fields has been proposed. To intensify the processes of separating gas, water and mechanical impurities and gas from drained water, preserve the light, most valuable hydrocarbon components of oil, prevent oil and gas losses and environmental pollution, it is proposed to introduce a three-product multihydrocyclone into the system of preliminary formation water discharge at the fields. To intensify the processes of separating gas, water and mechanical impurities and gas from drained water, preserve the light, most valuable hydrocarbon components of oil, prevent oil and gas losses and environmental pollution, it is proposed to introduce a three-product multihydrocyclone into the system of preliminary formation water discharge at the fields. At the same time, the water quality improves to values suitable for injection into injection wells without additional treatment.. Keywords: oil and gas condensate field, reservoir water, emulsion, demulsifier, three-product multi-hydrocyclone, oil, gas, intensification, mechanical impurities, centrifugal pumps, water discharge, gravitational forces, desalination, dehydration, oil treatment.
Was Kant a Methodological Interpretationist?
Authors: Lenk Hans
Published: July 2022

This paper examines Kant’s interpretive role of categories (Verstandesbegriffe) on the basis of his assertion in the Prolegomena § 30, where Kant claims that the role of categories is to spell out appearances in order to read them as experience. Kant’s metaphor of “spelling” or even “reading” is just a colloquial expression for the complexities of interpreting reality. The explanatory models that result from the relationship of the categories to the world of experience are conditions of our understanding and cognition of reality. I think we cannot simply hypostatize structures within a reality per se, but we should more sophisticatedly speak only of the hypothetical basic constitution of reality. Indeed, reality as such can only be conceived interpretatively, and the particular epistemological model itself can only be articulated from a higher meta-level of interpretation. We could also say that Kant is concerned with interpretations in the sense of applying given schematic forms or schemata in our use of language, i.e., that he is concerned with scheme-interpretation or schema-impregnation, insofar as the activity of the understanding consists essentially in interpreting experience by means of given schemata. In this paper, Kant’s theory of experience interpretation is supplemented by a more sophisticated distinction of different levels of interpretation and presented in the form of diagrams.

Published: July 2022

Background: Regardless of the cause, pulmonary hypertension can increase patient complications and mortality. This study compared the effect of nebulized versus intravenous (IV) milrinone on reducing pulmonary arterial pressure in patients with pulmonary hypertension candidates for open-cardiac surgery. Methods: This double-blind, randomized clinical trial was performed on 32 patients undergoing elective on-pump cardiac surgery during January 2021-January 2022 in the Cardiac Operating Room of Golestan Hospital, Ahvaz, Iran. Patients were randomly divided into test groups nebulize milrinone (N = 16) and IV milrinone (N = 16). The medication was administered after the cross-clamp of the aorta opening. The outcome variables included hemodynamic data, cardiac output, cardiac index, stroke volume, mean arterial pressure (MAP), central venous pressure, mean pulmonary artery pressure (mPAP), systemic vascular resistance, pulmonary vascular resistance, MAP/mPAP ratio, time until extubation, duration of hospitalization in the Intensive Care Unit (ICU), and duration of hospital stay. Results: In the nebulized group, MAP and MAP/mPAP were significantly higher than in the IV milrinone group (P = 0.09 and P < 0.0001, respectively). The time of extubation (P = 0.001), duration of hospitalization in the ICU (P = 0.009), and duration of hospital stay (P = 0.026) in the nebulized milrinone group were significantly shorter than in the IV milrinone group. Conclusions: Nebulized milrinone administration before weaning off cardiopulmonary bypass (CPB) can be accelerated and facilitate weaning off CPB. Moreover, despite maintaining MAP, nebulized milrinone significantly reduces mPAP. According to the results of this study, nebulized milrinone is recommended in patients undergoing cardiac surgery with pulmonary hypertension.
Group Excuse from Blameless Ignorance
Authors: Brown Jessica ,   University of Arkansas Press
Published: July 2022

We routinely treat groups, such as governments and corporations, as agents with beliefs and aims who are morally responsible for their actions. For instance, we might blame the government for its response to the coronavirus pandemic. If groups are morally responsible agents, then it’s plausible that they can have an excuse for wrongdoing from ignorance in just the way individuals can. For instance, a government might attempt to excuse its performance in the coronavirus pandemic by saying that it didn’t know how infectious the new variant was. In this paper, I assume that groups are morally responsible agents to develop an account of what it is for a group to have an excuse from blameless ignorance.
Epistemic Norms for Waiting (and Suspension)
Authors: McGrath Matthew ,   University of Arkansas Press
Published: July 2022

Although belief formation is sometimes automatic, there are occasions in which we have the power to put it off, to wait on belief-formation. Waiting in this sense seems assessable by epistemic norms. This paper explores what form such norms might take: the nature and their content. A key question is how these norms relate to epistemic norms on belief-formation: could we have cases in which one ought to believe that p but also ought to wait on forming a belief on whether p? Plausibly not. But if not, how can we explain this impossibility? I suggest that the best resolution is to view the traditional core norms on belief as themselves conditional in a certain sense, one that I think has independent plausibility. The results of this investigation may also tell us something about epistemic norms on suspension, on the assumption, which I defend elsewhere, that suspension is waiting.
Does Being Rational Require Being Ideally Rational? ‘Rational’ as a Relative and an Absolute Term
Authors: Siscoe Robert Weston ,   University of Arkansas Press
Published: July 2022

A number of formal epistemologists have argued that perfect rationality requires probabilistic coherence, a requirement that they often claim applies only to ideal agents. However, in “Rationality as an Absolute Concept,” Roy Sorensen contends that ‘rational’ is an absolute term. Just as Peter Unger argued that being flat requires that a surface be completely free of bumps and blemishes, Sorensen claims that being rational requires being perfectly rational. When we combine these two views, though, they lead to counterintuitive results. If being rational requires being perfectly rational, and only the probabilistically coherent are perfectly rational, then this indicts all ordinary agents as irrational. In this paper, I will attempt to resolve this conflict by arguing that Sorensen is only partly correct. One important sense of ‘rational’, the sanctioning sense of ‘rational’, is an absolute term, but another important sense of ‘rational’, the sense in which someone can have rational capacities, is not. I will, then, show that this distinction has important consequences for theorizing about ideal rationality, developing an account of the relationship between ordinary and ideal rationality. Because the sanctioning sense of ‘rational’ is absolute, it is rationally required to adopt the most rational attitude available, but which attitude is most rational can change depending on whether we are dealing with ideal agents or people more like ourselves.

Published: July 2022

This study aims to assess the Travel Time Reliability (TTR) in urban areas in Irbid city, Jordan, using a mobile application (Ultra GPS Logger), which retains the current location, speed, and time every three seconds. The study evaluated the TTR at the Origin-Destination (OD) level and the segment level. Each OD was divided into several segments with different interruption types to determine which segments have the lowest reliability and the most extended delay. The evaluation was based on several measures according to the Federal Highway Administration (FHWA), such as the buffer time, Buffer Index (BI), Travel Time Index (TTI), 95th percentile, standard deviation, and Coefficient of Variation. Chi-Square test for independence was carried to study the association between the period during the day, day of the week, and section type with the BI Level, and other combinations. Results showed that the normal sections, without traffic signals and roundabouts, had a significant effect on TTR compared with 3-Leg intersections, 4-Leg intersections, and roundabouts. Results also confirmed that trips reliability does not mean there is no delay or congestion, but there is some certainty in travel time prediction for a specific route and journey.
Procedure for Conducting a Towing Tank Test of a Waterjet Propelled Craft using Laser Doppler Velocimetery to Determine the Momentum and Energy Flux
Authors: Scherer Otto , Mutnick Ian , Lanni Frank
Published: July 2022

This paper describes the towing tank test procedure used for conducting propulsion tests of the Rolls-Royce Naval Marine (previously Bird-Johnson Co.) Advanced Waterjet 21 (AWJ-21™) propulsor. The tests were conducted on hull model 5565-1, an existing 22.5 scale model of a hull form representative of a future tumblehome naval destroyer. AII the test work described here took place at the Naval Surface Warfare Center, Carderock Divisions, David Taylor Model Basin. Design of the waterjet was carried out by Rolls-Royce Naval Marine in 1999 and the towing tank experiments were conducted in October 2000 and February 2001.

The test procedure follow the guidelines for the "momentum flux" method as described in Appendix A of the 21st International Towing Tank Conference (ITTC) Waterjet Group Report (1996] and reproduced in the Quality Manual of the 22nd ITTC Special Committee on Waterjets Report [1999]. However, the ITTC procedure does not address the methods for obtaining the required data and does not provide guidance for scaling the model data to the full size ship. The paper deals with these issues and some of the measurement procedures that are specific to the AWJ-21™ test program. In particular, an accurate survey of the inflow and discharge velocity distribution is required to obtain the mass flow and head rise through the propulsor. In the present case, a Laser Doppler Velocimeter (LDV) is used to carry out these surveys.

Because conducting LDV surveys is very time-consuming, it is not practical to determine the mass flow and head rise at every test speed by this method. In our case, the LDV surveys were conducted at only two speeds. · These data · are then used. to characterize the flow non-uniformity and to correlate with pitot-static probes located in the inlet and discharge of the jet system. With this correlation, the pitot-static probes are used to obtain the performance over the entire speed range.

While a Laser Doppler Velocimeter provides a very accurate means of obtaining velocity, it does not provide the required static pressure in the flow. It was found that by locating the inlet and discharge survey planes properly, the variation in static pressure over the survey area is small compared to the dynamic pressure and can be neglected. This permits the single static tap on the pitot-static probe to provide the required mean pressure. This paper describes the procedure for using the LDV survey to obtain the waterjet performance.
Development of New Standard Manoeuvring Test Methodology at the Institute for Marine Dynamics
Authors: Waclawek P. , Cumming O. , Earle G.
Published: July 2022

For standard maneuvering experiments, the Institute for Marine Dynamics (IMO) has traditionally used the classic approach - deploying free running models executing standard maneuvers such as turning circles and zig zags in an ocean basin environment. The primary disadvantage of using free-running models is the large planar area required for experiments. Often this limits the model size to a scale not deemed suitable for resistance/propulsion experiments and in many cases resulted in the requirement for two physical models when carrying out a full experimental program for a new hull form. In 1991, the effective working area of IMD's Ocean Engineering Basin (OEB) was reduced due to the installation of wavemakers and beaches. Free running ship maneuvering experiments are now impractical except for very small models.

This paper describes a new approach for carrying out standard maneuvering experiments under development by IMO that involves the derivation of hydrodynamic coefficients from Planar Motion Mechanism (PMM) experiments for input to a numerical simulation routine capable of generating standard ship maneuvers. An extensive experimental program was carried out to verify possible options in using PMM efficiently and to verify various testing configurations. The effort underway to build the analysis procedures into a compact site package, evaluate the methodology and develop a versatile on-line stand-alone analysis tool enabling immediate data verification and for complete on-line analysis is defined. Plans for validation the entire procedure against full-scale data are also described.
The Development of an archive of Naval Architecture and Ocean Engineering Laboratory Experiments
Authors: Waters Jennifer K. , White Gregory J.
Published: July 2022

Physical model tests are an invaluable asset to naval architecture and ocean engineering research, development, and education. However, the actual value of laboratory testing depends not only on the physical plant and technology available but also on the experience and expertise of the users. Recognizing this, the authors have undertaken a three-year effort to develop a high-quality record of numerous laboratory experiments performed within several naval architecture and ocean engineering courses at the U.S. Naval Academy (USNA).

The archive includes more than a dozen experiments performed in the Hydromechanics Laboratory (Hydro Lab) at USNA, ranging from ship maneuvering to. sediment transport studies. Each experiment record includes background information, experimental setup descriptions, and details, data records with analyses, as well as high-quality photos and video recordings of the experiments underway. An archive of this depth and quality has never been assimilated and it is anticipated that the naval architecture and ocean engineering community both inside and outside USNA will be able to reap many benefits from it. In order to provide the widest and easiest access to the work, a website is being created so as to make all of the products accessible via the Internet. This paper discusses the project, its development, and some of the details of the results obtained.
Statistical Prediction of Interference Effects on Resistance in High-Speed Trimarans
Authors: Slutsky Jonathan , Metcalf Bryson
Published: July 2022

This report considers the analytically predicted interference effects in a methodical series of 378 trimarans based on Series 64 hull forms. Wave interaction effects on drag were evaluated statistically to obtain a series of algebraic expressions for interference prediction based on form-related parameters and known resistance characteristics of the component monohulls. This technique could be used in early-stage design to predict the calm water resistance of an arbitrary set of component hulls in a trimaran configuration based on their known individual monohull resistance characteristics.

Five variables: side hull length, longitudinal position, transverse position, and the displacement to length ratio of the center and side component hulls (expressed in English units as D/(.01L)3), each having between two and seven values were used to define a family of 378 trimarans based on Series 64 parent hulls. Resistance for each configuration was calculated using the Total Ship Drag program developed at Naval Surface Warfare Center Carderock.

Interaction effects wer examined both qualitatively and through a multiple linear regression statistical treatment. The results of the regression were used to develop a method for predicting the calm water resistance of a trimaran composed of arbitrarily chose component hulls with known resistance characteristics.
Open Water Testing to Determine the Feasibility of Stereolithography as a Method for Propeller Model Construction
Authors: Brown Candace
Published: July 2022

Testing in the Robinson Model Basin (RMB) has long been a supplement to Webb Institute’s academic program, providing students with a comprehensive education in naval architecture. Since the theory and design of propellers is an integral part of an education in naval architecture, utilization of the RMB testing facilities should naturally accompany traditional classroom propeller theory. Having recently been provided an apparatus for the testing of propellers, students now need an adequate source of propeller models.

The typical cost to have a specially designed propeller model manufactured for testing either for a thesis project or for classroom study is well beyond the financial means of Webb Institute. Previously, Webb has relied upon the generosity of other institutions with established propeller testing facilities, such as the University of Michigan and the Naval Surface Warfare Center, Carderock Division (also referred to as David Taylor Model Basin, or DTMB), for the loan of propeller models. While these borrowed propellers have served their purpose in demonstrating classroom theory, there have been limitations in the applications for which the borrowed propellers could be used. An opportunity for students to see a propeller advance from design to production had yet to be established.
Measurement Techniques for Full Scale Test of a Submersible Walking Dredger/ Miner
Authors: Sarkar Sritama , Bose Neil , Sarkar Mridul
Published: July 2022

The use of surface floating dredgers in deep inland reservoirs, shelf areas and tidal inlets is limited by several operational restrictions and mobilization problems. Deployment of small, modular, autonomous to semi-autonomous submersible dredgers/ miners in these areas is expected to reduce the operational and mobilization constraints. Most of the existing submersible dredgers/ miners use tracks for locomotion on submerged ground. Legged locomotion is however favored in these natural unstructured terrains. A small, modular, walking submersible dredger/ miner is designed and a prototype is under construction. Prediction of the major design parameters of such a system requires a mathematical model integrating the processes of excavation, transportation of the excavated material and locomotion of the vehicle while moving on submerged ground. This paper gives a brief overview of the full scale tests to be performed with the prototype for validation of part of the mathematical model.
Ventilation effects on Cavitating Wedges and Struts
Authors: Gowing S. , Shen Y.
Published: July 2022

Reduction of ship hull skin friction can represent significant drag reduction for high-speed ships, especially those designed for low wave drag or using catamaran-type hull designs. A method is proposed to reduce this friction by shielding the side portions of the hull from the water using ventilated cavities created with protruding wedges. These wedges create low-pressure regions in their wake that naturally ingest air at the surface, reducing the drag of the wedge while lengthening their trailing cavities. The proposed scheme takes advantage of the natural combination of high speeds and low pressures that exist at the waterline of a high-speed ship without requiring auxiliary pumps or machinery. As a first step for engineering estimates of drag reduction, preliminary experiments are presented that use two-dimensional wedges and similarly shaped struts to validate theoretical ventilated-cavity predictions. Tests are conducted on parabolic and wedge-shaped sections and struts in a closed-jet water tunnel at 20 and 30 knots, using a pipe to ventilate behind the strut using natural suction. The wedge drag and back pressure and resulting cavity lengths are measured over a range of ventilation flows. The two-dimensional wedge drag shows fair agreement with linearized theory predictions at low cavitation numbers, and this drag can be reduced over 50% from its fully wetted value using natural ventilation. The change in drag is attributed mostly to the change in the pressure on the back of the wedge caused by the ventilation. The measured ventilated cavity lengths are close to linear theory models using a double spiral vortex for cavity closure conditions. For the range of ventilated conditions tested, the air flow rates required for ventilation are only a few percent of the equivalent flow rate swept out by the passage of the strut through the water. These flowrates could become much greater at lower pressures representative of shallower depths.

Published: July 2022

O retrato de Bethencourt da Silva é uma complexa composição do artista catarinense Sebastião Vieira Fernandes. O personagem central dessa obra, Bethencourt da Silva, é o idealizador e mantenedor do Liceu de Artes e Ofícios, local onde Sebastião Fernandes teve formação e atuou como professor até seus últimos dias. A composição criada para homenagear Bethencourt celebra também o aniversário de fundação do Liceu, que, ao lado da Academia Imperial de Belas Artes, foi um dos principais centros de ensino de artes no Brasil. Através da leitura detalhada dos elementos figurativos e da estrutura compositiva, procura-se entender um pouco mais do caráter do retratado tal como apresentado pelo pintor, e, por conseguinte, reconhecer também um pouco da linguagem poética do artista. Da mesma forma, é perceptível que a conexão entre artista e retratado desenvolvida pelo vínculo destes com o Liceu se materializa nas cores e formas desta pintura.

Dolgoročni potek in izid bolezni pri bolnikih z intermediarnim uveitisom s spremljanjem vsaj 20 let

Izhodišča: Intermediarni uveitis (IU) je kronična vnetna očesna bolezen z glavnino vnetja v steklovini. Gre za redko bolezen s kroničnim potekom, ki prizadene predvsem delovno aktivno populacijo in lahko povzroči začasno ali trajno izgubo vida. Namen naše študije je preučiti dolgoročni potek IU pri bolnikih z vsaj 20-letnim spremljanjem.

Metode: Gre za retrospektivno presečno študijo dolgoročnega poteka IU pri bolnikih z vsaj 20-letnim spremljanjem. V študijo so bili vključeni vsi bolniki z IU z začetkom spremljanja v uveitični ambulanti Očesne klinike med letoma 1985 in 1995. Študija je zastavljena kot nadaljevanje že objavljene študije Vidovič Valentinčič in sodelavcev z 10-letnim spremljanjem iste kohorte bolnikov.

Rezultati: Iz začetne kohorte 29 bolnikov z IU smo 20 bolnikov spremljali vsaj 20 let s povprečnim časom spremljanja 25,3 let (95% IZ 23,2–27,4). Po 20 ali več letih spremljanja je remisijo doseglo 17/20 bolnikov s povprečnim časom do remisije 11,14 let (95% IZ 7,94– 14,34). Do ponovnega zagona bolezni je po povprečno 8,2 letih (95% IZ 2,8–13,6) prišlo pri 6/17 bolnikov z remisijo. Odstotek slepih in slabovidnih oči je postopoma naraščal do 10 let, nato pa se je stabiliziral. Po 20 ali več letih je bilo slepih ali slabovidnih 28,2 % oči. Glavni vzrok za izgubo vida je bil cistoidni makularni edem (CME) z razvojem makularne atrofije.

Zaključek: IU je kronična bolezen z dolgotrajnim potekom, pogostimi zapleti, ki lahko povzročijo trajno izgubo vida, in ponovnimi zagoni, zaradi česar je potrebno dolgoročno vodenje bolnikov z IU, zgodnje diagnosticiranje in intenzivno zdravljenje CME.
Nosotras también estuvimos (2021) y el punto ciego de la masculinidad en guerra
Authors: Ehrmantraut Paola
Published: July 2022

El documental argentino Nosotras también estuvimos, estrenado el 1 de abril de 2021 y dirigido por Federico Strifezzo propone un recorrido por la memoria de tres mujeres que se desempeñaron como enfermeras de campaña durante la guerra de Malvinas. El documental da testimonio de sus vivencias durante la guerra cuando atendieron con profesionalismo a los conscriptos heridos. La memoria se va dibujando como un ejercicio político que culmina en un acto transgresor: las enfermeras ubican una placa recordatoria en un monumento a los veteranos de Malvinas cerca de donde se desempeñaron como enfermeras, monumento en el que no estaban representadas. En este trabajo propongo una lectura desde los estudios de la masculinidad para analizar el efecto de este acto que a pesar de su carga transgresora termina por reafirmar una organización patriarcal de género.

Pensar la Guerra de Malvinas desde la lente del teatro: Piedras dentro de la piedra (2012), de Mariana Mazover
Authors: Dubatti Ricardo
Published: July 2022

Cuarenta años han transcurrido desde la Guerra de Malvinas (2 de abril – 14 de junio de 1982). Sin embargo, su persistencia como acontecimiento histórico (Badiou, 2015) hace que al día de la fecha siga marcando unos de los sucesos de mayor impacto para la Argentina del siglo XX. Esto se refleja en manifestaciones no solo sociales o políticas, sino también culturales, signadas por la presencia de imaginarios recurrentes. El presente trabajo busca ofrecer algunas líneas teóricas en torno a cómo el teatro ha producido representaciones singulares de la guerra, tomando como referencia el caso de Piedras dentro de la piedra (2012), de Mariana Mazover, espectáculo inspirado de forma libre sobre la novela Los pichiciegos (publicada originalmente en 1983), de Rodolfo Fogwill.

Peasant farms of Western Siberia on the way to commodity-market relations: factor analysis of data from the Tomsk Provincial Agricultural Census of 1901
Authors: Antonova Evgeniia Konstantinovna , Zinov'ev Vasilii Pavlovich
Published: July 2022

The article considers the application of factor analysis in the study of peasant farms of the Oyashinsky volost of the Tomsk province on the materials of the Tomsk provincial agricultural Census of 1901. The analysis of the primary materials of the agricultural census of 1901 was carried out on the basis of factor analysis, namely, the method of main components, which provides "compression" of information, explaining the many available features through a small number of generalized factors, which allowed us to consider the internal structure of the peasant economy of the agricultural and livestock specialization of the Oyashinsky parish, and also compare the results obtained with the results of factor analysis According to the census of 1901, the analysis of the socio-economic structure of peasant farms of agricultural and livestock specialization of the transition zone showed that the entrepreneurial way of life was leading in all peasant farms, but the general small-scale farms reduced the level of their involvement in capitalist relations. Peasant agricultural farms and livestock specialization of the transition zone of the Tomsk province at the beginning of the XX century never joined the developed capitalist relations. The materials of the 1901 census make it possible to analyze in detail the influence of various factors on the state of the peasant economy of Siberia at the turn of the XIX–XX centuries. These materials are suitable as a mass source for studying the peasantry of Siberia and for local research.
Historical network analysis: to the fifth anniversary of the profile international journal
Authors: Borodkin Leonid , Gasanov Arsenii Alanovich , Danilov Evgenii  Vladimirovich
Published: July 2022

This article is a review of materials published in the international journal Journal of Historical Network Research (JHNR), which has been in existence since 2017 and reflects the main approaches in the development of historical network research. This is a relatively new direction in historical science, reflecting the growing interest in the study of interactions, relationships in historical societies of various epochs and localizations. The methodological basis of historical network analysis is the methods of graph theory. A big role in these studies is given to the visualization of the results of the analysis of social networks with the help of special software actively used in the publications of the journal JHNR.   Some issues of the journal are thematic – for example, reflecting the experience of using network analysis methods in the study of antiquity or the history of China. JHNR magazine is an online publication with open access, which creates a number of advantages for researchers of social networks. Thus, network illustrations are not subject to restrictions on the size or nature of the visualization. The article analyzes the experience of using network methods in the study of informal communications in the elites of Ancient Rome, relationships during coastal trade in Tudor England, network communications in the opposition community of the late GDR, as well as the network structure of the conspiracy of July 20, 1944.
