Authors: Voytkiv S. V.
Published: August 2023

Purpose. The main objective of the work is to develop and analyze the optimal layout of an articulated two-section tramcar for the creation of promising competitive models of cars of a significantly higher technical level, as well as to assess the prospects for their mass production provided that the maximum passenger capacity is ensured. Methodology. Based on the analysis of the regulated technical requirements for the dimensional parameters of tramcars, maneuverability parameters and permissible loads on their wheeled bogies, as well as on the analysis of the main technical parameters of existing models of single and two-section tramcars equipped with two biaxial wheeled bogies - body length and curb weight - the permissible length of their bodies and the estimated weight in the equipped state were determined. Two biaxial wheeled bogies were replaced by four uniaxial bogies. Findings. An innovative layout of an articulated two-section tramcar based on the use of four single-axle wheeled bogies and minimization of overhangs of body sections was proposed and developed, provided that the maximum length of a single tramcar and the track of wheeled bogies and the width of the car were preserved. A methodology has been developed for assessing the effectiveness of the proposed design solutions and the comfort of passenger transportation by single and two-section tramcars with two biaxial and four single-axial wheeled bogies, the preliminary designs of which have been developed according to three different layout schemes. Originality. For the first time, a layout of an articulated two-section tramcar is proposed based on an innovative solution - the use of four uniaxial wheeled bogies instead of two biaxial ones. A methodology for analyzing and evaluating the feasibility of using the proposed layout for creating promising models of a two-section tramcar has been developed. Practical value. The choice of an optimal innovative layout scheme with four uniaxial wheeled bogies for the creation of promising competitive models of articulated two-section tramcars with optimized parameters of their body length and nominal passenger capacity with higher passenger comfort compared to existing analog tramcars has been substantiated at the stage of developing draft proposals.

Purpose. The main purpose of this work is to substantiate the design features of sandwich panels for the manufacture of container walls of size 1SS. Methodology. To ensure the strength of the container walls, it is proposed to use sandwich panels as their components. This involves the manufacture of a sandwich panel from two metal sheets, between which a material with energy-absorbing properties is placed. This solution helps to improve the strength of the container by reducing its load. To determine the thickness of the panel sheet, the corresponding calculations were performed using the Bubnov-Galerkin method. It is taken into account that the sheet is a thin-walled plate subjected to an evenly distributed load. To improve the stiffness of the sheet, it is proposed to make it corrugated. The analysis of the corrugations has led to the conclusion that it is most appropriate to use corrugations with a rectangular configuration. Findings. The strength of the sandwich panel was calculated. The spatial model of the sandwich panel was created in the SolidWorks software package, and the strength calculation was performed in SolidWorks Simulation, which implements the finite element method. The calculations took into account the most unfavorable loading mode of the container during rail transportation - shunting impact. The calculation was performed on the example of the container's end wall, since it is the wall that is subjected to the highest loads in the event of a shunting collision with a platform car. The strength calculations showed that the maximum stresses in the sandwich panel made of corrugated sheets are about 258 MPa, which is 16% lower than the permissible stresses. The maximum displacements in the sandwich panel assemblies occur in its middle part and are equal to 3.1 mm. Originality. The design of the sandwich panels that form the end walls of the container is scientifically substantiated. The rational configuration of the corrugations of the sandwich panel sheets is determined. Practical value. The study will contribute to the development of recommendations for the design of modern modular-type vehicle structures and improve the efficiency of the transport industry.

Purpose. This article is aimed at analyzing the wear process of locomotive wheelset and rail bands in curved sections of the rail track using the formalization of the ridge wear indicator for the wheelset slippage cycle. Methodology. In the process of developing a model for the wear of a locomotive wheelset, the phenomenon of slippage during the realization of traction torque was considered and the sliding speed functions at the point of contact between the wheel and the rail were determined. On the basis of the obtained functions, an analytical expression for determining the wear factor of the rims and ridges is proposed. To simplify practical calculations, the concept of the relative wear rate of the wheel ridge is introduced and an analytical expression for its determination is proposed. Findings. Our studies show that the slippage of locomotive wheelsets during the realization of traction torque is one of the decisive factors that determines the wear of the ridges. A significant reduction in the resulting ridge slip during slippage can be achieved by reducing the response time of anti-skid devices. It should also be noted that the resulting slip decreases to a greater extent than the speed of the snowplow protection increases. Originality. In this study, for the first time, a model of the wear process of wheel set tires and rims during locomotive slippage is proposed in a curve, where the wheel rim wear factor is represented as the total work of friction forces per slippage cycle. Practical value. The proposed analytical model can be used to predict the service life of locomotive wheel sets and to standardize train weights on railroad sections with a complex track plan and profile.

Authors: Novodvorskyi V. V. , Ivanitsky G. K.
Published: August 2023

Purpose. Polymer products are used in industry due to their performance properties. The homogeneity of the melt is essential for the quality of the final product. Uniform distribution of components and properties ensures homogeneity of the product's physical and mechanical characteristics. Insufficient homogeneity can lead to defects in the product. The homogenization zone plays an important role in ensuring a homogeneous melt. In a disc extruder, the homogenization zone consists of four consecutive channels. In order to describe the flow for the entire homogenization zone, it is necessary to model the first channel first. Therefore, the main purpose of this work is to model hydrodynamic and thermal processes during the flow of a non-Newtonian fluid in a straight annular channel in a non-isothermal regime, as well as to create a general procedure for further calculations for other channels. Methodology. The analysis of publications was carried out. The procedure for calculating the velocity and shear rate of the longitudinal and tangential melt flow, the effective melt viscosity, and the calculation of the melt temperature change along the length of the annular gap in an analytical form was developed. Findings. In accordance with the developed procedure, the values of tangential and longitudinal velocities and shear rates were calculated. The graphical dependences of the distribution of tangential and longitudinal velocities and shear velocities of the melt flow along the width of the annular channel, the distribution of pressure and the temperature of the polymer melt averaged over the width of the gap along the length of the annular channel are presented. Originality. In this work, a stationary flow in a straight annular channel was modeled for LDPE of the 15803-020 grade in a non-isothermal regime. A general procedure for further calculations for other channels of the homogenization zone has been developed. Practical value. The given calculation procedure can be applied to the following channels of the homogenization zone, which allows describing the melt flow for the entire homogenization zone.

Purpose. Increasing the operational indicators of suburban transportation on railways electrified by alternating current due to the modernization of traction static converters of ER9M electric trains. Methodology. The methodological basis of the study is the general theoretical provisions and principles of the system approach of theoretical electrical engineering, the theory of power converters. The main principles of construction of traction static converters of electric rolling stock of railways are used. Findings. The analysis of the basic rectification schemes of alternating current electric trains was performed. As an alternative scheme, it is proposed to introduce a controlled rectification scheme based on a four-zone rectification scheme, which is similar to electric locomotives, which allows using most of the known advantages of non-contact traction electric drive control systems. Some energy figures are calculated for the fully controlled and semi-controlled circuit. As a result of the comparison, the modernization option based on a semi-controlled rectification scheme was selected. The required values of starting power of the transformer and power factors for schemes with uncontrolled, fully controlled and semi-controlled rectifiers are determined. A selection of modern semiconductor elements is offered for the configuration of converters. It was shown that in the case of modernization of the rectifier scheme, there is no need for significant capital investments due to the preservation of the main traction transformer and traction motors of the electric train. Practical value. The obtained results can be used by enterprises that carry out major repairs of alternating current electric trains.

Published: August 2023

Purpose. The study of the real state of master plans of existing industrial enterprises in our country indicates that today the planning decisions of some industrial enterprises, especially metallurgical ones, which were built in the twentieth century, to a large extent do not correspond to the classical principles of designing master plans. Achieving the economic effect of production at the enterprise depends on the enterprise’s logistics. Therefore, the purpose of the work is to study the problem of the influence of existing master plans on the way to improve the transport service of the enterprise’s workshops and the efficiency of the industrial enterprise logistics as a whole. Research methods The study used methods of analysis and synthesis to study the issue, as well as analysed the main scientific publications on the impact of existing master plans on the industrial enterprise’s logistics. Results. In the work, using the experimental method of data analysis of the implemented enterprises’ master plans, a study was made of existing master plans’ influence on improving the workshop transport service of the enterprise and the efficiency of the industrial enterprise logistics as a whole, which indicate the need for new effective methods and proposals that take into account the transport functioning peculiarities. The scientific novelty lies in the development of a general method for the impact determining of existing schemes of master plans on transport costs and emergency occurrence. The main direction of improving the transport services efficiency for an industrial enterprise and logistics, in general, is a comprehensive reconstruction of the enterprise territory, taking into account the performance of transport and storage works in order to increase the efficiency of the territories using, reduction of auxiliary production, re-profiling, placing adjacent or other non-production functions, solving environmental problems based on the best domestic and foreign scientific developments.

JUSTIFICATION OF APPROACHES BEFORE PLACEMENT OF PASSENGER VESSELS IN THE DIRECTIONS OF THEIR WORK AND IMPROVING THE WORK PLANNING OF THE SHIPPING COMPANY’S FLEET
Authors: MYKHAILOVA IU.
Published: August 2023

Abstract. The purpose of the article is to solve the task of arranging the passenger fleet and improving the planning of the fleet of the shipping company. To achieve the goal, the possible operating conditions of the passenger fleet were studied; developed approaches that will allow, taking into account different types of sailing, different directions of work, sizes of ships, as well as the possibility of replenishment of the fleet, to obtain the maximum value of the financial result when deploying the passenger fleet of the shipping company, which made it possible to improve the planning of the passenger fleet of the shipping company. The process of managing a shipping enterprise is a continuous development of management decisions, which largely depends on the final result of the work of any company. This is especially important for shipping, which functions in conditions of significant dynamics of both the external environment and the direct production of transport processes. The proposed solution will allow the shipping company to effectively locate its fleet, obtain the maximum financial result, taking into account the conditions of transportation and operation of vessels of various types of navigation, forms of organization of transportation, various types of vessels, routes, and also takes into account the possibility of replenishing the fleet of the shipping company in the event that its potential freight capacity does not exceed the amount of transport work. One of the most important areas of the shipping company’s work is planning and optimizing the use of the company’s resources. The shipping company strives for the maximum financial result from the work performed. If we consider the "external environment" as a management subject that also makes decisions corresponding to the options of the possible structure of passenger flows, then this kind of task can be formalized and presented in the form of a matrix game. A characteristic condition is that each party has no information about the decision of the other. Thus, the maximin (minimax) principle is implemented in a conflict situation. The value of the game determines the mathematical expectation of winning the first player, that is, the value of the financial result, which should be taken as planned. As a result, the forecast of the results of the shipping company will reflect the production capabilities of the "external environment" (the second player) and the conditions in which it will have to work. The proposed approach can also be used to determine the values of the planned indicators of other maritime transport enterprises - ports, ship repair plants, as well as standards of transport work; development of the replenishment (write-off) program of the shipping company’s fleet; determining the tariff policy related to the transportation of passengers in the shipping company’s region.

Published: August 2023

The purpose of the study is to develop appropriate algorithms and procedures used in simulating the movement of a model car along adjacent tracks. These algorithms will automate the process of calculating the position of the boundary column between adjacent tracks of different designs with a given accuracy and compliance with traffic safety requirements. Scientific methods. In the course of the study, simulation methods were used to model the movement of the design car along the adjacent tracks. Analytical geometry methods were used to determine the main geometric characteristics of the car in terms of its relative position relative to the track axis. Results. The following conclusions were obtained as a result of the research. The multivariability of the design of adjacent tracks in the plan does not make it possible to create a universal analytical expression for determining the position of the boundary column. Existing methods for calculating the position of the boundary post provide for the maximum spread of the dimension in curved sections, which results in an excessive distance between the boundary post and the switch and inefficient use of the useful track length. The developed algorithms and procedures for determining the position of the boundary column are universal and allow automating the process of calculating the position of the boundary column between adjacent tracks of different designs in the plan, even when technical standards or parameters of the design cars change. In this case, only the initial data for the calculation need to be changed. Scientific novelty. The scientific novelty lies in the development of algorithms and procedures for formalizing the design of adjacent tracks and simulating the movement of design rolling stock on them. Practical significance. The developed algorithms and procedures can be implemented in the form of a software package for automated calculation of the position of the boundary column with high accuracy. Also, the obtained results of calculations can be used in the analysis and creation of an analytical description of the position of the boundary column for complex structures of adjacent tracks.

Objetivo: Este artículo pretende destacar, en diálogo con los supuestos marxistas, los matices de la precariedad del trabajo docente en Brasil, engrosando y problematizando la llamada educación remota como estrategia adoptada en tiempos de pandemia de covid-19. Metodología: En las concepciones teóricas y metodológicas del materialismo histórico dialéctico, se buscaron vías para una reflexión crítica sobre el tema, desde una perspectiva coyuntural, con respecto a las influencias ideológicas, económicas y políticas y los ataques a la labor docente. Los análisis son referenciados en ofensivas capitalistas y neoliberales que consuelan las condiciones materiales y simbólicas del trabajo de los docentes. Resultados: Los resultados, en busca de una discusión original, revelaron que algunos procedimientos prescritos para el trabajo docente pueden ser leídos y entendidos como (re)actualizaciones del trabajo precario. Conclusiones  y  discusiones: Como conclusiones, a la luz de los supuestos marxistas. señalamos que la precariedad docente se refiere a proyectos conservadores y reaccionarios en disputa por la hegemonía en contextos sociales, mediáticos y políticos, que ya se habían practicado antes de la pandemia, y que, antes de ella, ha demostrado ser una poderosa iminencia de mercantilización de la educación y el vaciamiento del sentido político y ontológico del acto de educar.

Particle paths beneath small amplitude periodic forced waves in a shallow water channel are investigated. The problem is formulated in the forced Korteweg-de Vries equation framework which allows to approximate the velocity field in the bulk fluid. We show that the flow can have zero, one or three stagnation points. Besides, differently from the unforced problem, stagnation points can arise for small values of the vorticity as long as the moving disturbance travels sufficiently fast.

Published: August 2023

The presence of drugs in the environment, such as ibuprofen, has raised concern due to their persistence and high-risk potential to local biota and health of exposed population. Thus, removal methods, such as biochars adsorption, gained notoriety for their high efficiencies and reduced production cost. Therefore, the present study developed a systematic literature review regarding the advance of low-cost adsorbents for ibuprofen removal from aqueous media. It was possible to observe certain increase in the production of studies within this subject, with preference of agricultural residues as precursor materials. Pyrolysis temperatures on literature ranged from 200 to 900 °C, depending on the process. Note that two substances (H3PO4 and NaOH) are used with more frequency, for chemical activation and superheated vapors in physical activation processes. Regarding chemical adsorption process, the pH was one of the most relevant factors for adsorption process and, also, most of the authors reported better fit to the pseudo-second order kinetic model; that is, adsorption process generally happening by chemisorption.
Mapping of scientific research on ecotoxicological analysis with zebrafish (Danio rerio) in textile effluents between 2011 and 2021
Authors: Raíza Alves Cavalcante Paula , Cândido Passos da Silva Rodrigo , Gonçalves Cadena Pabyton , Gomes Tavares Rosângela
Published: August 2023

The high load of pollutants in textile industrial effluents makes it necessary to carry out an ecotoxicological analysis. Mapping these analyses in animal models can help clarify the possible toxicity that these textile effluents have. Thus, the present study aimed to map the evolution of scientific publications regarding the use of zebrafish (Danio rerio) as a bioindicator animal model for environmental quality analysis in the ecotoxicological analysis of textile effluents over a ten-year horizon (2011 to 2021). Three methodological steps were established: a sampling of articles, scientometric and bibliometric analyses, and a systematic literature review. It was observed in twelve documents that ecotoxicological studies of textile effluents using zebrafish are a recent and understudied but promising trend. Among the works, those originating from the Asian continent stood out. The Environmental Science and Pollution Research journal had only two publications. The similarity analysis generated a word tree with seven groups (halos). It was understood that industrial textile effluents have a direct connection with toxicity caused by dyes, and this toxicity can be detected by analysis carried out with the zebrafish bioindicator. It was observed that ecotoxicological assessments with zebrafish could be carried out through different methodologies. However, some proved more complex and presented more robust results, such as embryonic and larval analyses. These analyses were considered beneficial compared to other animal models because they are low cost, require a short period, and comply with an internationally imposed standard (OECD 236). Therefore, it concluded that zebrafish is a promising model for ecotoxicological analysis of textile effluents.

Published: August 2023

Professional development of university instructors has always been an important aspect of the educational environment, which requires appropriate methodological support. It is aimed at creating conditions for improving educational activities and transforming it in accordance with advanced achievements in scientific, practical, and innovative fields. This is necessary to improve the quality of professional training of teaching staff. The content of methodological support is considered in several directions, including active use of innovative technologies in the educational process, development of theoretical foundations for forming creative potential of teaching staff, and assistance in mastering competencies in accordance with the Federal State Educational Standards. This study focuses on the discipline of Academic Writing and creating conditions for professional development of instructors who teach this discipline, since organizing conferences, seminars, and workshops for academic writing instructors and providing opportunities for professional development in this area do not always meet the demand and growing interest in this aspect. The experience of creating and participating in a reading group for one year is presented. The main goal of the group was to develop participants understanding of the concept of academic writing as well as to discuss effective teaching methods for this discipline in higher education institutions. Various pedagogical theories and concepts of academic writing, a critical evaluation of existing writing teaching practices in Russian universities were also considered. The process of the group work, its results, and the advantages and disadvantages of this form of interaction for professional development were described. In conclusion, the reading group is proposed as an opportunity for foreign language instructors not only as a form of methodological support for continuous professional development but also as an opportunity for collaboration in the educational environment of the university.

The paper proposes to pay attention to the study of speech situation of apology by foreign students on the example of modern fiction text analysis. Since reading as a kind of speech activity is connected with the cognitive function of the language, the proper selection of texts in the classes of Russian as a foreign language contributes to the application of the factual information contained in them in practice, as well as increasing linguocountryological competence of students. The research updates the role of speech etiquette in the aspect of linguo-country studies and raises the problem of finding relevant and communicatively valuable material for teaching, the selection of such texts that would be available for intercultural discussion. Choosing the story Sorry, Fool by the childrens writer Asya Petrova, the authors describe the advantage of modern childrens literature over other sources and aim to create productive intercultural communication in the classroom. Analyzing the situation of an apology at advanced levels of language proficiency, the authors consider an apology as a communicatively defined event that takes into account contemporary realities and extra-linguistic factors. A system of exercises and questions, including the traditional complex of text tasks: pre-textual, by-textual and post-textual exercises aimed at the formation of the behavior culture and the development of oral speech, is proposed for the formation of students communicative skills. The research resulted in the testing of the presented work in practical classes with foreign students on topics related to speech etiquette and human speech culture. The authors note that the affective reading on the example of Asya Petrovas story Sorry, Fool proved to be effective in practice, contributed to the creation of a situation of success in the organization of international communication and allowed to implement the participants intentional promotion of the principles and values of their culture in the class.

Authors: Yue Yanfeng
Published: August 2023

To match the teaching demands of STEM talents with global competence, an innovative intralinguodidactic methodological approach has been designed and experimented in curricular constructions of STEM English education. In this research project, the construction of English reading course is focused on achieving the training aim of global competence. The aim of this paper is to develop a practical curricular framework of Scientific Literature Reading on the methodological base of intralinguodidactics. The object of this paper is to evaluate the intralinguodidactic curricular framework of STEM English course. The subject is to examine the effectiveness of employing intralinguodidactics as a methodological basis for curricular design. The relevance of this project has been proven by the teaching practice in three aspects: interconnection, decentration, and compatibility. The teaching practice proves that global competence is a set of knowledge, skills, competencies and personal qualities allowing STEM talents to develop communicative competence of a foreign language. And global competence is shaped by future careers of a graduate. Hence, the educational process of STEM English acquires a new meaning, that is, it becomes a process of the autonomous cognition and digestion of English information literacy materials entertaining professional and sociocultural significance.
Unsuccessful pedagogical situations
Authors: Dobrova Victoria V.
Published: August 2023

On the basis of the previous theoretical and practical research conducted by the author, in this paper the concept of pedagogical situation is studied. The suggested classification of pedagogical situations is based on the ability of a pedagogical situation to solve pedagogical tasks, reach pedagogical problems, achieve a pedagogical effect and thus to become a pedagogical event. On these basis as well as on the logic and practice of a teacher's everyday work, the three types of situations were previously identified. One type of these situations is described in this paper. The goal of such situations is unachievable, which means that the situation can not change from a potential situation to an actual situation. The goal-oriented principle of analysis opens up the prospect of establishing relationships between all the parameters of the situation and the personal characteristics of its participants. The scheme for describing pedagogical situations logically includes the following components: participants (teachers and students a potential pedagogical agent), goal/task, conditions (locus).
Role of information and communication technologies in the development of listening skills of non-linguistic students at a technical university
Authors: Shvaikina Nina S. , Popel Alexander A.
Published: August 2023

This paper focuses on a particular type of modern technologies, i.e. information and communication technology which has emerged as part of digital didactics. These technologies have brought about dramatic changes in all walks of life as well as in our expectations of what students should learn to survive in a new technological world. In their future work students will have to deal with large volumes of information obtained digitally, to use digital tools to work not only in Russian, but also in a foreign language (English). Consequently, it is necessary to teach them how to operate digital tools while teaching them the language. Among the most challenging speech activities, it is listening comprehension that challenges learning the most and requires longer time to develop at technical university due to insufficient number of hours given to the discipline called Foreign (English) Language in engineering faculties. Thus, the object of the research is the process of developing listening skills of nonlinguistic students in foreign (English) language classes. The subject of the research is interactive tasks based on web-services, aimed at developing their listening skills. The aim of the research is to create and test listening comprehension tasks on the platform of web services during lessons of foreign (English) language for students of non-language direction at technical university. To follow up listening skills and search for new audio texts the authors suggest using Randall's ESL Cyber Listening Lab resource and AI-based Andy application which simulates native speech. Based on a four-month (one semester) experiential study these resources have proven themselves effective.
Supremum Distribution of Weighted Sum of Random Processes from Orlicz Spaces of Exponential Type with Continuous Deviation
Authors: Tykhonenko Dmytro , Yamnenko Rostyslav
Published: August 2023

The paper studies distribution of sum of random processes from Orlicz spaces of exponential type weighted by continuous functions, in particular, processes from spaces Subϕ (Ω), SSubϕ (Ω) and class V (ϕ, ψ) are considered. Such spaces and classes of random variables and corresponding stochastic processes provide generalizations of Gaussian and sub-Gaussian random variables and processes and are important for various applications, for example, in queuing theory and financial mathematics. We derive the estimates for the distribution of supremum of weighted sum of such processes deviated by a continuous monotone function using the entropy method. As examples, weighted sum of Wiener and weighted sum of fractional Brownian motion processes with different Hurst indices from classes V (ϕ, ψ) are considered. Corresponding estimates of the probability of exceeding by trajectories of such weighted sums a positive level determined by a linear function are obtained. In the insurance risk theory, such aproblem arises during estimating a ruin probability of the corresponding risk process with a constant premium income, and in the communications theory, it appears for the buffer overflow probability for a single server with a constant service rate.

O objetivo do estudo foi investigar o desenvolvimento profissional de uma treinadora brasileira expert de taekwondo. Com base na literatura, foi elaborada uma entrevista semiestruturada sobre desenvolvimento de treinadores(as) para a coleta dos dados, os quais foram analisados de acordo com o método de análise de conteúdo utilizando-se a abordagem dedutiva. Além disso, outros temas pertinentes sobre o desenvolvimento da treinadora emergiram de forma indutiva durante a análise dos dados. Os resultados demonstraram que diferentes variáveis contribuíram para o desenvolvimento da treinadora expert de taekwondo, como características pessoais da treinadora, situações de aprendizagem em contexto formal, não-formal e informal e apoio positivo de familiares e amigos(as). Entre os resultados, destaca-se a influência da carreira como atleta de alto rendimento, assim como o conhecimento do idioma inglês, este contribuindo e facilitando a atuação da treinadora durante competições internacionais. Em conclusão, o presente estudo fornece informações valiosas sobre a escassez de treinadoras experts no taekwondo brasileiro, o que pode ter implicações significativas para o desenvolvimento da modalidade e para a promoção da igualdade de gênero no esporte.
Estado e Sociedade Civil no Processo de Migração Venezuelana

O presente artigo apresenta uma síntese dos resultados da pesquisa desenvolvida nos marcos do pós-doutoramento no Programa de Pós-Graduação em Sociedade e Fronteiras, com bolsa da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), na Universidade Federal de Roraima, entre 2018 e 2020. Tem como objetivo analisar o papel exercido pelas organizações/entidades da sociedade civil atuantes na questão migratória na época da pesquisa que se engajaram na Operação Acolhida. Os dados obtidos pela pesquisa de campo, através de entrevistas semiestruturadas (abertas) com interlocutores-chaves e da observação participante nos diferentes espaços de atuação dessas entidades/organizações, evidenciaram um intenso protagonismo desses atores no enfrentamento de situações de precariedade, de violação de direitos, de hostilização contra os migrantes, além de intensa pressão política por resposta governamental. Não obstante, após o estabelecimento da Resposta Humanitária oficial em 2018 e, portanto, da inserção das entidades como colaboradoras na Operação Acolhida, a atuação desses atores foi se reconfigurando. As ações de assistência, consideradas emergenciais, prevaleceram sobre as ações de incidência política. Na ausência de pressão social por uma política pública efetiva, a gestão migratória mantém-se há cinco anos pautada em um modelo de emergência permanente. Tal processo sugere a importância de (re)pensar criticamente o modelo vigente, os interesses que o atual modelo atende e o papel da sociedade civil organizada na transformação da ajuda humanitária emergencial em política migratória.

Governments employ public policies to intervene in the agricultural sector of their respective countries. The AGRIMONITOR initiative carries out different Agricultural Policy Indicators for the analysis of the agricultural sector at a regional level. This infographic illustrates the level of support provided to the agricultural sector as a whole through services such as research, development, training, inspection, marketing, and promotion. The indicator used is the General Service Support Estimate (GSSE), which is expressed as a percentage of the Total Support Estimate (TSE).
