Репресії у промисловому секторі міжвоєнної Катеринославщини – Дніпропетровщини (1920-30-ті рр.)
Authors: Іваненко Валентин
Published: September 2022

Актуальність даної теми зумовлюється потребою розширення та поглиблення існуючих знань про масштаби і специфіку радянсько-російського державного терору в одному з найбільших регіонів  УСРР окресленої доби, особливо у контексті сучасної повномасштабної війни Росії проти України. Метою статті є спроба структурувати і узагальнити основні напрямки та особливості репресивної політики тогочасного правлячого режиму у промисловому секторі Катеринославщини-Дніпропетровщини.

Методи дослідження: проблемно-хронологічний, компаративний, описовий. Основні результати. На значному фактичному матеріалі показано, що з приходом до влади більшовиків в умовах активного спротиву з боку освіченої частини суспільства, його інтелектуального, заможного ядра, насильство, репресії швидко були зведені в ранг державної політики й стали мало не нормою соціальної практики в ході започаткованих радикальних перетворень; акцентовано, що вони захопили буквально всі сфери життєдіяльності країни та верстви населення, включаючи базові опори нової влади – індустрію і робітничий клас як ключового «гравця» у ленінській формулі «диктатура пролетаріату»; встановлено, що саме представники робітництва, керівного та інженерно-технічного корпусу промислових підприємств займали провідне місце (майже 43 відсотка) у фаховій структурі репресованих в ті часи мешканців краю. Авторські тези та версії проілюстровані на прикладах конкретних «замовних» справ чи «напрацювань» спецслужб по лінії протидії страйковому руху на початку 1920-х рр., нейтралізації осередків, керівників і учасників політичної опозиції, «економічної і націоналістичної контрреволюції», а також окремих особистостей.

Зроблено загальний висновок про те, що внаслідок терористичної політики і практики Кремля з піком масового беззаконня та свавілля середини 1930-х рр. із виробничої сфери вилучалася, по суті, еліта, найпродуктивніша частина людського капіталу промисловості Дніпропетровщини. Оригінальність і наукова новизна статті полягає насамперед у постановці та розгляді теми як самостійного об’єкта дослідження, актуалізації, систематизації і оприлюдненні відповідного конкретно-історичного матеріалу. Тип статті: оглядова.
Міжнародні телекомунікаційні зв'язки Азербайджанської республіки (1991-2001 рр.)
Authors: Карімлі Самір Салім оглу
Published: September 2022

Акт про суверенітет, прийнятий азербайджанським парламентом 18 жовтня 1991 року, відкрив нову сторінку в історії нашого народу. Відновлення державної незалежності Азербайджану призвело до фундаментальних змін у всіх сферах. Одним із важливих завдань нашої країни була перебудова економіки, управління, інфраструктури, а також зв'язку, успадкованих з радянського періоду. Протягом перших десяти років незалежності - 1991-2001 рр., радикальні реформи, проведені в країні відповідно до вимог нової епохи, спонукали до розвитку комунікації, яка була одним із національних стратегічних напрямів держави. У той час роль комунікації була незамінною через розширення приватного сектора, організацію спільних підприємств, щороку збільшуючи інвестиційні надходження до державного бюджету. Тому комунікація відігравала важливу роль у розвитку економіки країни та відродженні економіки.

Комунікація відіграла незамінну роль у встановленні міжнародних відносин з різними країнами світу, поряд із зміцненням державної незалежності. Протягом досліджуваного періоду Азербайджанська Республіка була членом міжнародних організацій зв'язку, а також підписала двосторонні угоди з іншими країнами в галузі зв'язку, у 1992 році приєдналася до Міжнародного союзу електрозв'язку та в наступні роки до інших організацій зв'язку. Рівень обслуговування у сфері міжнародного зв'язку з кожним роком підвищувався, були запущені телефонні та супутникові телефонні канали, а Азербайджан приєднався до Трансазіатсько-європейської волоконно-оптичної кабельної лінії, міжнародного комунікаційного проекту під назвою «Контракт cтоліття». Маючи стратегічно вигідне положення, Азербайджанська Республіка створила умови для транзиту телефонного трафіку в ряд країн світу, а також для отримання додаткового фінансування країни.
Основні особливості позитивістського, психоаналітичного і соціологічного підходів до визначення поняття “політична пропаганда”
Authors: Герасименко Олександр
Published: September 2022

В політичній науці і науці загалом термін “пропаганда” використовується дуже широко. Це явище може стосуватись будь-якої сфери суспільного життя. Також, дане поняття широко вживане і на рівні звичайних громадян, а не лише в науковому дискурсі. Такий стан речей навколо поняття “пропаганди” спричинений особливостями історичного, суспільного і політичного минулого України, Європи і світу.

Через існування тоталітарних держав нацистської Німеччини і СРСР, і використання ними пропагандистського впливу, дане поняття закарбувалось у пам’яті пересічно людини саме як синонім до чогось брехливого, негативного і злочинного. Ситуація ускладнювалась також відсутність в даний історичний період засобів ефективних і незалежних масової комунікації. Тому, поняття “пропаганди” існує також у форматі міфу у свідомості більшої частки людей.

Метою статті є розгляд основних характеристик політичної пропаганди і її відмінностей від суто пропаганди, а також виокремлення основних особливостей вказаних підходів до її визначення.

Актуальність даного дослідженням зумовлена необхідністю формулювання чіткого розмежування “пропаганди” і “політичної пропаганди”, а також розкриття змісту основних підходів до її визначення.

Методами дослідження є: компаративний метод, метод аналізу першоджерел, історичний метод.

У статті розглянуто та проаналізовано основні особливості підходів до визначення поняття “політична пропаганда”, зокрема позитивістського, психоаналітичного і соціологічного, а також їх вплив на сучасну політичну науку.

Authors: Dogea Ramona , Yan Xiu T. , Millar Richard
Published: September 2022

Aluminium alloys (AA) are ubiquitous materials in manufacturing used in powder bed fusion (PBF) processes due to light weight, high strength and corrosion resistance. Current research focuses on other materials whilst additively manufactured AA 7050 remains unexplored. This paper examines the formability of AA 7050-T7451 powder for the Selective Laser Melting (SLM) process. To define this material in Simufact AdditiveTM the creep behaviour required flow curves obtained by writing a MATLAB® script to calculate the true stress–strain behaviour depending on strain rate and temperature. The results of the mechanical calibration for aluminium alloy are presented to obtain its inherent strains.

Authors: Moral Luis , Latorre Sara , Toral Teresa , Marco Nuria , Canals Francisco , Forniés María José , González María Cristina , García-Avilés Belén
Published: September 2022

Background: Drug provocation tests (DPTs) are considered the gold standard for diagnosing beta-lactam allergy. However, positive results tend to be mild and difficult to interpret. This study aimed to describe pediatric patients with a presumedly positive or inconclusive DPT, assess the decision to repeat the DPT, and describe its outcome.
Methods: Retrospective review of all presumedly positive or inconclusive DPTs performed in six pediatric allergy clinics from 2017 to 2019. We describe the interpretation of results, focusing on the decision to repeat the DPT and its outcome.
Results: Of 439 children challenged with a beta-lactam, 26 (5.9%) with a presumedly positive or inconclusive result were included in this study. Most were girls (n = 16, 61.5%), and the median age was 5 years (range 1–13). The initial DPT used amoxicillin (n = 13, 50.0%), amoxicillin-clavulanic acid (n = 12, 46.2%), or cefadroxil (n = 1, 3.8%). Reactions were early (n = 11, 42.3 %), delayed (n = 14, 53.8 %), or not registered (n = 1, 3.8 %), but mild in all cases. A second confirmatory DPT was proposed in 19 patients (73.1%) and performed in 17 patients (65.4%). Nine DPTs were performed from 1 day to 4 months after the first DPT, and the remaining eight took place 6 months to 2 years later. Fifteen children tolerated the drug in the second DPT: 88.2% of those reevaluated and 57.5% of the whole study group.
Conclusion: The positive predictive value of DPT may be lower than expected. Given the mildness of observed reactions, a second confirmatory DPT is warranted within a few weeks or months.
THE STRENGTH OF UNDERGROUND HORIZONTAL WORKINGS OF ELLIPTICAL CROSS-SECTION SHAPE SUBJECTED TO ALL-ROUND UNIFORM PRESSURE
Authors: Bogomolov A. N , Ushakov A. N , Bogomolova O. A
Published: September 2022

The paper presents the results of a study to determine the stress state on the contours of underground workings, the cross-section of which has the form of an ellipse with a fixed value of the large semi-axis. For workings of this type, at different values of the ellipse parameter, the permissible depths of laying and the values of uniform pressure at the points of their contours are determined, at which normal tangential stresses do not exceed the tensile and compressive strength limits of the host rock. Based on the strength condition used in the work, the values of the permissible depths of the workings are calculated for varying values of uniform pressure applied at the points of the workings contours and the specified values of the lateral expansion coefficient of the rock. The permissible values of the stretching uniform pressure at the points of the contours of the elliptical shape of the cross-section with a change in the depth of laying, the specified values of the lateral expansion coefficient of the rock and the ellipse parameter are given. In addition, the paper presents formulas on the basis of which the problem of stress distribution at the points of contours whose cross-section has the shape of an ellipse with a fixed value of the large semi-axis is considered. It is established that when the intensity of the stretching uniform pressure applied at the points of the contours of the workings of an elliptical cross-section shape changes, and the specified values of the ellipse parameter, the depth of the workings and the magnitude of the lateral expansion coefficient of the host rock, sections of the contours on which tensile and compressive stresses act are highlighted. When changing the depths of the workings of the elliptical cross-section shape, sections of contours are identified on which tensile and compressive stresses act at given values of the ellipse parameter, the intensity of the stretching uniform pressure applied to the points of the contours, and the values of the lateral expansion coefficient of the rock.
Assessment of seismic resistance of multi-storey buildings under seismic impacts on weak subsidence soils
Authors: Zainulabidova Kh. R
Published: September 2022

Under the influence of dynamic and static loads, the volumes of weak soils in the base change due to a decrease in porosity. In this regard, studies of the stability of the building under seismic influences, the bases of which are elastic-plastic layers, have been carried out. As a result of the research carried out in this paper, an equation of ground motion was obtained to determine the general angle of inclination of the building, taking into account the seismic impact characteristic of the construction site and the characteristics of the building itself. An increase in the risk due to the loss of stability of the base due to the possible slope of the building is shown. The mechanism of soil weakening, which leads to the overturning of buildings, is analyzed and justified. The parameters affecting the kinematic characteristics of buildings and structures are shown. It is determined that an elastic system consisting of a building and a base has one-way connections between the foundation and the base, which are removed under the influence of seismic forces in certain areas of the foundation sole, where the static load is insignificant. Removing the links causes a change in the rigidity of the system. The center of gravity and the center of mass are shifted by a certain distance, therefore, there are changing fluctuations. The range of vibrations in this case depends on the ratio of the natural frequencies of buildings and seismic waves. It is known that when a building under the influence of external forces receives a certain slope relative to the vertical axis, then there is a decrease in the load, a dependence is obtained to determine the load reduction coefficient. The paper considers a practical solution to the problem of stability on the example of a 50-meter building. Based on the general principles of earthquake-resistant construction in the calculation of overturning, several calculations of buildings were carried out using the initial data for frequent and weak impacts, moderate strength and rare strong impacts. The results of the research can be applied to the calculations of multi-storey and high-rise buildings built on weak deformable soils, along with other calculations that allow increasing seismic resistance.
Formation of the "Self-Made-Man" Idea in the Worldview of the Renaissance and Reformation
Authors: Korkh O. M , Antonova V. Y
Published: September 2022

The purpose of this study is the reflection on ways of philosophical legitimation for the "Self-made-man" idea in the worldview of the Renaissance and Reformation. Theoretical basis. Historical, comparative, and hermeneutic methods became the basis for this. The study is based on the works of Nicholas of Cusa, G. Pico della Mirandola, N. Machiavelli, M. Montaigne, E. Roterodamus, M. Luther, J. Calvin together with modern researchers of this period. Originality. The analysis allows us to come to the conclusion that casts doubt on the still widespread belief according to which the emergence of the "Self-made-man" idea is localized by the process of forming the American cultural code and the ideological heritage of Benjamin Franklin. It is highlighted that the formation of this idea is the result of a long process that originated in the ancient world and gains a special impetus in the Renaissance and Reformation. Precisely in the cultural context of the latter, the ancient intention to recognize the individual’s right to self-determination and self-government, which in the depths of Christian theology acquires only a potentially universal character, becomes not only acceptable but also, in the context of Protestantism worldview, the only admissible, in fact, individual’s obligatory life guidelines. Conclusions. Humanistic and reformation thoughts quite naturally led to further ideological legitimation of the person’s idea of who is creating oneself. This legitimation was during the complex interaction of numerous factors of culture in the Late Middle Ages, as well as ideas and intentions inherited from Antiquity. Key among them was the gradual formation of a new social order, in essence, indifferent to paternalistic rudiments, together with the ethics of Protestantism corresponding to it. The latter does not only legalize but, de facto, sacralizes the individual’s reorientation from hopes for the synergy of God’s grace and own free will in personal salvation, toward the self-reliance and personal efforts, awareness of personal responsibility for the own fate as key principles of the "Self-made-man" concept.
The Spirituality of Hryhorii Skovoroda’s Work in Taras Zakydalsky’s Research
Authors: Alchuk M. P , Pavlyshyn A. D
Published: September 2022

The purpose of the article is to introduce into scientific circulation works by Ukrainian scholar Taras Zakydalsky on the philosophy of Hryhorii Skovoroda. Taras Zakydalsky is a representative of the Ukrainian diaspora, philosopher, and member of Canadian NTSh (Shevchenko Scientific Society of Canada). Theoretical basis. We consider the uniqueness of H. Skovoroda’s philosophy, which stimulates not only intellectually but also spiritually enlightens the reader. The reasons for the complex perception and interpretation of Hryhorii Skovoroda’s philosophy are highlighted. We have verified the main methods of its interpretation given in the works by Dmytro Chyzhevskyi. The influence of philosophical thought of thinkers of Antiquity and the Middle Ages: Aristotle, Epicurus, the Church Fathers, and Tertullian has been studied. We have comprehended H. Skovoroda’s interpretation of the Bible as a two-layer existence, the symbolic world that makes the foundation of his philosophy. The peculiarity of the thinker’s division of the heart into "internal" and "external" is analyzed. Hryhorii Skovoroda’s position on the Good and the evil is stated. The Good is identified with God, and the evil – with the real world, the man can choose between the two. Much attention is paid to the understanding of man as a microcosm – rational thinking, and thought is the fundamental cause of human activity, which generates all existence. Hryhorii Skovoroda’s philosophy of metaphysics as the existence of three worlds is highlighted: the first is the macrocosm (the whole surrounding world), the second is the microcosm (the man), and the third is the symbolic world (the Bible). "Monodualism" as a characteristic feature of H. Skovoroda’s work is analyzed. We have highlighted H. Skovoroda’s attitude to the transcendence of God, which is not separated from the world but is present in it directly. The understanding of faith as a forced act of self-love is analyzed because by loving ourselves we love God. The criteria for true and false faith have been clarified. The significance of H. Skovoroda’s aphorism that what is necessary is useful, and not useful is unnecessary is considered. Examples of ethical principles in H. Skovoroda’s philosophy are considered. Peculiarities of the concept HAPPINESS are revealed. This concept is a universal means of existence of the Good, its source is gratitude to God. Originality of the article is in the systematic presentation of the philosophy of the heart by Hryhorii Skovoroda and the analysis of the integrity of the "inner man", the true meaning of life as interpreted by Taras Zakydalsky. Conclusions summarize the "anthropological pragmatism" of the philosopher, whose main idea is to apply practical skills for the benefit of society.

Published: September 2022

Purpose. The aim of the work is to substantiate the technological parameters of effective use of reinforced soil-cement piles obtained by jet mixing technology. Such studies are needed to determine the possibility of increasing the bearing capacity of pile foundations in the body of earthen structures of buildings and roads. Methodology. Determination of bearing capacity of reinforced soil-cement piles was carried out by reasonable choice of structure, soil base, material, depth of piles in accordance with engineering and geological conditions, structural scheme of the structure and method of their arrangement. Findings. Significant differences in soil engineering and geological elements in plan and depth necessitated an in-depth study of soil characteristics, so it was decided to determine their strength and deformability based on static probing of reinforced piles. Analysis of the results of static studies showed that the soil-cement pile, reinforced with a reinforcing frame, has a higher bearing capacity in soil and material, and the unloading branch confirms the fact that in specific conditions the soil and piles work in elastic mode. Originality. It consists of the obtained dependences of the change of vertical loads on the reinforced soil-cement pile, created on the basis of brown mixing technology. Graphs of the dependence of the values of deformations occurring during the action on the reinforced soil-cement pile under static loading and unloading are obtained. Practical value. In practical conditions, the solution for the manufacture and testing of static load of the experimental reinforced soil-cement pile was implemented at the construction site. The manufacturing technology is designed so that the spatial frames of the soil-cement element with a length of 5…7 meters are immersed under their own weight, and the frames of 12 and more meters are lowered with a vibrator.

Authors: POPOVICH M. M. , KLIUCHNYK S. V.
Published: September 2022

Purpose. The aim of this work is to construct an approximate solution of stationary oscillations of a nonlinear equation with a cubic characteristic. The design scheme under consideration best corresponds to the operating conditions of the girder structure in the event of defects of the supporting parts. In this case, longitudinal forces may appear in the girder of the girder structure. Methods. The paper investigates nonlinear oscillations of girder structures of small bridges. The undamped oscillations of the beam resting on hinged fixed support parts on both sides from the action of periodic unilateral impulse loading are considered. The design scheme differs from the statically defined beam scheme, which takes into account defective support parts. In the article, the possible transition to the beam system on moving support parts is considered. To solve the nonlinear equation of the second order of a single-span beam taking into account the longitudinal force, a method of variable time scale used, developed by Academician of the Academy of Sciences of the USSR, professor Bondar M. G. The method of variable scale gives fairly approximate solutions to this class of problems. Results. An approximate analytical solution is performed by the method of variable time scale of stationary nonlinear oscillations of the girder structure taking into account the longitudinal force caused by one-sided pulses that are periodically repeated. According to the obtained formulas of the solution of the nonlinear equation with cubic characteristic it is easy to construct amplitude-frequency characteristics and forms of oscillations. Originality. For the first time the solution of the equation of oscillations of a beam taking into account longitudinal force is executed. The criteria of impact resonance for the system without friction, as well as taking into account the viscous friction. An expression for the amplitude-frequency characteristic of the system under consideration is obtained. Practical meaning. Studies of beam structure oscillations taking into account the longitudinal force gave practical value in the possibility of analytical calculation of oscillation forms, shock resonance criteria and amplitude-frequency characteristics of the system from the action of periodic unilateral impulse loads. The system of girder beams takes into account defective supporting parts (jamming of movable supporting parts) of girder structures of small and medium railway bridgesd.
OPTIMISATION MODEL’S CONCEPTUAL FORMS FOR THE CONSTRUCTION PRODUCTION SYSTEM OF CONTRACTING COMPANIES ON THE EVOLUTIONARY COMPUTATION PLATFORM
Authors: SAIKOV D. V.
Published: September 2022

Purpose. The study consists in development and implementation in the latest construction practice of scientific and methodological approaches to differentiation and planning of the construction organisational processes for contracting companies at the stage of initiating the project implementation with deterministic financing conditions. Identification of optimisation’s conceptual foundations takes into account the current situation in the domestic market of construction services, the economic conditions of contracting companies. Methodology. The choice of theoretical and methodological tools for optimising the contractor’s organisational processes is based on an analysis of the company's available material and technical resources, comparing them with the distribution value of construction works within the framework of the development and financing contractor’s strategy, increasing its competitiveness. The methodology for modeling the system of organisational processes is created on the platform of the construction works’ evolutionary strategy, that is, on the basis of optimal trajectories’ set for regulating processes, evolutionary strategies are created taking into account the standard operators of evolutionary computation. Results. Using of the operator of randomly determined exchange (crossing), corresponding to the inheritance’s natural process, shows the transfer of properties to new evolutionary strategies (descendants). After the crossing stage’s end, operators of random change in evolutionary strategies (mutations) are executed. The above operators are used repeatedly, which in turn leads to a gradual change in the original population. The generation process lasts until a deterministic level of convergence is reached, i.e. the resulting population reaches a given fitness-function (objective function of task optimisation). If the stopping criterion is the population’s quality, the speed of the method is estimated by the time it takes to reach this property. Originality. Genetic algorithms show significant implementation characteristics of solving problems of the organisational processes optimising for construction, in particular calendar and business planning. The methodological foundations of evolutionary computation, including the use of computers, greatly simplify operational tasks and contribute to obtaining the desired result. Practical value. Population structuring makes it possible to increase the efficiency of the search algorithm for optimal management of organisational processes. Evolutionary computation gains legitimacy in the interactive construction production regulating of contracting companies. Their use is justified especially in those cases when the exact optimum is not required in the management of construction processes – any value that is better than the directive or standard value can be considered a solution.

THE ROLE OF RAILWAY TRANSPORT IN THE EVACUATION OF THE POPULATION DURING HOSTILITIES IN UKRAINE
Authors: PAVLENKO O. , PAVLENKO I.
Published: September 2022

In the extremely difficult time of aggression by the Russian Federation, the first and most important task for Ukraine's railway transport is to provide logistics for the transportation of humanitarian and military aid, as well as internal movement (evacuation) of the population. The state transport is covered by 2-5 times increased van traffic and passenger traffic. In such a situation it is necessary to control the number of passengers at the stations, to provide them with assistance and advice. The volunteer movement is one of the important conditions for the functioning of the state in wartime. Volunteers at the stations ensure the distribution of passenger flows in individual directions and provide advice on the schedule of trains. Humanitarian aid is now arriving in large quantities and needs to be delivered as soon as possible to places where it is most needed, to cities where active hostilities are taking place and to cities where the flow of internally displaced persons is concentrated. The logic of the movement of passengers must be clearly formed, because in a difficult emotional and physical state, people have a hard time understanding the course of action and the requirements for the carriage of passengers. After analyzing the formed passenger flows in the first days of evacuation, the main directions of movement of citizens were determined. The analysis revealed that the number of passengers in evacuation trains heading west to the country could cause overcrowding in the receiving cities and cause a collapse in urban transport, settlements and food supply. These are the main issues facing the government and the logistics system for moving people and goods across the country. The solution to the acute problem was the possibility of simplifying passenger transportation and the organization of international trains with allied countries, where there is the possibility of transportation without changing the rolling stock through different track widths. The development of such routes has made it possible to simplify the logistics of population movement and reduce the burden on the border service of Ukraine. To reduce the crowds after crossing the borders of Ukraine, a schedule of trains from the nearest railway stations of neighboring countries was developed together with the neighboring states, which facilitates the movement of migrants within the routes of passengers. The second problem is the overcrowding of trains and the complexity of their equipment for flights, as well as the establishment of a system to provide them with drinking water on the routes. Due to sufficient technical equipment, coordinated work of railway transport workers, and their high executive discipline, this chain has been successfully implemented.

The purpose. Sorting wagons on slide devices is one of the most responsible and dangerous processes. Risks arising in the process of disbanding trains can lead to railway accidents with serious consequences. One of the operations of the process of sorting wagons is their braking during rolling, which is a complex operational task with many criteria, and shoe braking is also related to the presence of people in a dangerous zone. Therefore, the goal of the research is to increase the safety of the technological process of breaking up cars on the sorting chute by assessing the risks of the speed controllers and determining the priority measures to minimize them. The Methodology. The system analysis procedure for identifying potential failure modes, their causes and consequences for the operation of FMEA and the analysis of the types, consequences and criticality of FMECA failures with means of ranking the severity of failure modes were chosen as research methods. The results of the survey of two professional groups were chosen as the initial data. The results. A statistically established list of railway accidents and accidents for the profession of train speed controller was offered to two groups of specialists, 10 people in each group, to assess the severity, probability and possibility of prevention in the form of questionnaires. Using the FMEA method, the three components of the RPN risk priority number for each type of hazard are established and the dangerous cases that can happen to the rail speed regulators are placed in descending order. The obtained final ranks showed the consistency of opinions on certain characteristics within the group and their practical uniformity for the two professional groups. Risks with the highest priority and risks with low estimates of the probability of occurrence and prevention of the event, but with high estimates of consequences, have been established. Practical significance. For all components of the RPN – S, O, D, the agreement of opinions is sufficient and the evaluations of two groups of experts can be used for further research. the priority of which is the highest according to the results of the performed studies.

The Design Process and the Building Site: Leonardo da Vinci at Milan Cathedral as a case study
Authors: Ceriani Sebregondi Giulia
Published: September 2022

The involvement of Leonardo da Vinci (1452-1519) in the competition for the design of the dome of Milan Cathedral in 1487 offers a window onto many aspects of architectural practice and management in the early modern period. It allows us to investigate several features of the building site administration, the design process, and the complex decision-making processes of several large Italian building projects. Many written sources document the construction of the dome of Milan Cathedral, primarily administrative notes and book accounts. Only through a detailed aggregation and analysis of those data, given the long history of the building, can those aspects be philologically reconstructed. Up to now, the sources related to Leonardo’s involvement with the Milan dome have been analysed mainly for his ideas on architecture and to exalt his exceptionality, which has isolated the artist from his own time and his project from its background. This article re-reads this case study of the 1487 competition for the dome in the context of the cathedral's entire building history, to point out different aspects of architectural and management habits of early modern building projects, together with aspects of Leonardo’s design process.
Desigualdades en la escuela secundaria argentina: recorridos escolares y proyecciones educativas
Authors: Santos-Sharpe Andrés , Núñez Pedro
Published: September 2022

Este artículo versa sobre las formas de subjetivación de la desigualdad social en estudiantes del último año de la secundaria, en la Ciudad Autónoma de Buenos Aires, Argentina. Se plantea una línea teórica útil para analizar la desigualdad educativa y pensar su configuración en el contexto de la pandemia provocada por la covid-19. Con este trabajo se exploran las lógicas desde las cuales las y los jóvenes proyectan sus trayectorias educativas o laborales postescolares. En este sentido, se recuperan las discusiones sobre cómo caracterizar la educación secundaria y los procesos de socialización entre sectores similares. La propuesta principal del artículo consiste en retomar la siguiente pregunta: ¿cómo se sedimentó la desigualdad social en las experiencias estudiantiles? A partir de tal interrogante se profundiza en el análisis de los tipos de recorridos y las expectativas que las y los estudiantes del nivel secundario construyen en su experiencia educativa para entender el procesamiento subjetivo de la desigualdad. Al concluir, se muestra la expresión actual de las tensiones y complejidades a la par de la expansión en la cobertura de la escuela secundaria y las nuevas líneas de diferenciación que se conforman. Así se evidencia la importancia de prestar atención a la interrelación entre aquello que las instituciones creen ofrecer desde su propuesta escolar y las expectativas del alumnado acerca del futuro.

Published: September 2022

En este artículo, se presentan los resultados de investigación, referidos a la percepción de un grupo de estudiantes chilenos de educación secundaria sobre la convivencia escolar, los cuales son pertenecientes a establecimientos de alta vulnerabilidad. Este ejercicio se desarrolló comparando la percepción de aquellos que presentan necesidades educativas especiales de tipo transitorio (n = 47) y permanente (n = 24), respecto de aquellos con desarrollo típico (n = 546). Se analizó entonces, el grado de predictibilidad que podría tener la convivencia escolar percibida respecto de su desempeño académico. Los análisis constatan que los estudiantes con Necesidades Específicas de Apoyo Educativo tienen una percepción más desfavorable en casi todas las dimensiones analizadas. Un análisis de regresión lineal muestra que el 26.2% de la varianza de su desempeño académico puede ser explicada por las variables incorporadas en el modelo, destacando el rol importante y positivo de la asistencia a clases y el peso negativo de las situaciones de indisciplina percibidas al interior del aula.
Intentionality and Dualism: Does the Idea that Intentionality Is the MOM Necessarily Entail Dualism?
Authors: Tortoreto Andrea
Published: September 2022

It is well known that Franz Brentano was the first to suggest intentionality, the property of being about something, as a criterion for demarcating the domain of the mental. He suggested that intentionality is a necessary and sufficient condition for something to qualify as a mental event. It is important, for the purposes of this paper, to pay attention to the fact that Brentano’s theory came from within a broader philosophical outlook that was thoroughly dualistic. He sought a total separation of the mental from the physical, and his appeal to intentionality as a defining criterion for the mental is in the service of producing such a separation. In Brentano’s view, only mental events have intentionality, and it is in virtue of this feature that they differ from the events of the physical world. The aim of this paper is to explore whether Brentano’s intentionality criterion for defining the domain of the mental is committed to the broader dualism from which it originated.
Is Presence Perceptual?
Authors: Minden Ribeiro Max
Published: September 2022

Perceptual experience and visual imagination both offer a first-person perspective on visible objects. But these perspectives are strikingly different. For it is distinctive of ordinary perceptual intentionality that objects seem to be present to the perceiver. I term this phenomenal property of experience ‘presence’. This paper introduces a positive definition of presence. Dokic and Martin (2017) argue that presence is not a genuine property of perceptual experience, appealing to empirical research on derealisation disorders, Parkinson’s disease, virtual reality and hallucination. I demonstrate that their arguments fall short of establishing that presence is not perceptual.
