Base price determination for IPL mega auctions: A player performance-based approach
Authors: Chittibabu Vaseekaran , Sundararaman Malolan
Published: February 2023

Indian Premier League (IPL) is the most popular T20 domestic league in the world. An essential aspect of this league is the “Mega-Auction”, which is of focus in this study. The mega auction occurs once every three years, and it is found that the auction process is inefficient as the time taken is long (∼2 days). This is because players specify their base price. Thus, this study focuses on the efficiency of the auction process and addresses it by prescribing the base price for players. The base prices are prescribed such that they are as close to the actual auction price of a player. Accordingly, in the past, only two mega auctions occurred in 2014 and 2018, and both are considered in this work. Here, a two-stage algorithm to determine the base prices of players is proposed. In the first stage, K-Means clustering is used to group players. The base price for players allocated to a cluster is proposed using a developed assignment logic in the second stage. An empirical demonstration of the proposed algorithm indicates that the auction process has been made efficient as the time taken decreases by ∼17.6% and ∼31.1% for Indian and foreign players, respectively.
LOGICAL DIMENSIONS OF THE GLOBAL ECONOMIC WORLD
Authors:   Taras Shevchenko National University of Kyiv, Filipenko Anton S.
Published: February 2023

The article addresses logical approaches to explaining the economic world. The introductory part reveals the general prerequisites for the logical analysis of large systems. The rest of the study is devoted to the logical structure of economic worlds: at micro-, macro- and mega-levels. The logical dimensions of the economic world are based mainly on deterministic logic, grounded in Antiquity, Modern era and institutional logic of the late XIX and XX centuries. The dynamics and structure of the micro level (enterprise, firm, MNE) is explained by the institutional logic based on the American school (R. Coase, O. Williamson, etc.). Institutional logic in a broad sense includes values, norms, customs that people use in their daily activities on the scale of a certain space and time. Economic institutions have a long history, accompanying socio-economic development from the Neolithic era to the modern one. Their logic was shaped by the level of social, economic, technological, cultural development of various human communities of the ecumene. The macro-level of economics, on the one hand, is defined by deterministic (Laplace’s) logic. Its essence is to take into account the whole set of possible factors (economic and non-economic ones) that affect the course of economic dynamics. Individual needs, preferences, productive capacity, interaction of individuals create the layout of neoclassical model of economy. Keynesian deterministic logic is structural in nature, when the behaviour of individuals is determined by the general state of the economy as a whole. The logic of Marxist economic analysis, also known as overdeterminism, is derived from dialectics. On the other hand, the works of T. Veblen, the old American school of institutionalism and modern representatives (D. North, R. Nelson, J. Winter) are of paramount importance. The tools of logical analysis of the mega-level are mostly reflected in the works of G. Leibniz, I. Kant, R. Carnap and in modern institutional logic. The logic of globalisation, its historical phases can be traced according to different types of globalisation in four spatio-temporal dimensions: extensiveness, intensity, velocity and reciprocity and three deterministic logics: technical (technological), economic and political.

The purpose of the conducted research is to develop indicators of the structure of the share capital of joint-stock companies and methods of their quantitative determination, as well as to explore the impact of the distribution of shares on the distribution of the management resource of the company among the owners of shares. In modern studies, much attention is paid to the issues of quite complex interaction of different groups of shareholders in the process of creating and running a relevant business. The article proves that the nature of these relationships, their effectiveness and features of corporate management of the enterprise are largely defined by the structure of shares distribution in the company. A group of indicators is proposed for characterizing the structure of shares distribution in a jointstock company: concentration, dispersion and differentiation of share capital. A methodology of their quantitative calculation has been developed. The indicator of share capital concentration shows the degree of concentration of share capital among the company’s participants, which makes it possible to accurately determine whether a particular joint-stock company belongs to a certain model of corporate governance. The indicator of share capital differentiation shows the extent to which packages of shares within a jointstock company differ in volume and, accordingly, in the management resources of their owners. The concept of collective and individual management resources in a joint-stock company has been introduced. The article reports a methodology for calculating the management resource of each package of shares, which allows to determine more accurately and quantitatively the available opportunities for managerial influence of their owners on the enterprise’s activity compared with the use of nominal indicators of the size of the share packages. It has been revealed that the deviation of the values of the shareholders’ management resources from the indicators of the relative sizes of their packages of shares occurs as a result of the differentiation of the share capital. The specified dependence is proportional – the higher the capital differentiation is, the more significantly the available management resource of shareholder deviates from the nominal value of his package of shares, and vice versa. The indicator of share capital dispersion characterizes the degree (depth) of the division of the statutory share capital into separate parts (packages of shares). It has been found that this indicator by itself does not affect the implementation of the management function, i.e. it is indifferent (insensitive) to the parameters of establishing the management control in the company.

Authors:   Yanbu Industrial College, Yanbu Industrial City, Alfazzi Faiz
Published: February 2023

SMEcos (Small and Medium Ecopreneurs) are critical players in the circular economy and achieving the goal of sustainable development. This is especially true because SMEcos have long been the backbone of economic progress, and entrepreneurs make a significant contribution to the sustainable use of natural resources and the reduction of development problems. Therefore, this research looks at the problems and opportunities faced by small and medium-sized ecopreneurs. The terms “sustainable development”, “circular economy”, and “ecopreneurship” have been discussed in the research. It also considers how SMEcos might contribute to the development of a circular economy. As a theoretical framework, the survey is based on sustainability theory. To conduct thorough study, relevant and accurate learning theory and reports have been employed. Entrepreneurs face four major challenges: financial availability and accessibility; a lack of planning, competent labor, and appropriate management skills; a lack of competitiveness, technical innovation, and consumer loyalty; and a lack of legal and regulatory framework as well as social considerations. The SMEs offers significant potential for entrepreneurial development, according to the results. New entrepreneurs are frequently confronted with rivalry, unforeseen business obstacles, and other reasons when faced with external hurdles. In addition, the results of the study have revealed a number of concepts that can help entrepreneurs overcome difficulties, such as being optimistic in the face of difficulties, spreading an idea and vision to potential investors, etc.

The main research objective is to analyze behavioral styles of members of the enterprise development project team in conflict situations using the Thomas-Kilmann method and graphic techniques to show the importance and value of such analysis for preventive conflict management in business entities. The work has been performed in the following logical sequence: characteristics of behavior styles; survey of members of the project management team using the Thomas-Kilmann method; description of data using graphic techniques; context diagram of the process of analyzing the behavior styles of project team members in a conflict situation. According to the results of the survey of the project team members on the manifestations of a particular behavioral style in a conflict situation based on the Thomas-Kilmann method, diagrams and analysis (“petal” and “bubble”) have been presented. The diagrams allowed: to compare scores of the project team members demonstrating different behavioral styles in a conflict situation; to evaluate the ratio of project team members behavioral styles, identify the dominant style; with the help of visual aids to find out which group includes a particular behavioral style in terms of the level of its manifestation (weak, medium and strong. The obtained results indicate the feasibility of testing employees to determine the prevailing behavioral styles in a conflict situation for further consideration of data in the personnel management process. A matrix of project team members behavioral styles in a conflict situation and their characteristics in terms of cooperation and assertiveness have been presented. Radar charts, scatter plots and comparative histograms of the behavioral styles of the project team members in a conflict situation have been designed. The contextual diagram with the analysis of the behavioral styles of the project team members in a conflict situation has been given. This study has been conducted in the specific Ukrainian cultural and organizational context. The results of the research can be useful for Ukrainian industrial enterprises in order to achieve projects results for enterprise development.
DETERMINANTS OF ECONOMIC AID OF EU MEMBER COUNTRIES TO UKRAINE IN THE CONDITIONS OF THE RUSSIAN-UKRAINIAN WAR

The article examines the issue of economic assistance from EU member states to Ukraine to overcome the negative consequences of the Russian Federation’s military aggression against Ukraine. In the economic literature, the issue of Russia’s military aggression against Ukraine is focused mainly on the analysis of sanctions and other measures aimed at increasing pressure on the Russian economy and reducing its potential for military aggression. Less attention in the literature has been paid to the supportive measures for countries that have suffered from external military aggression. Therefore, the analysis of systematic data on the economic aid of the EU countries to Ukraine will provide an opportunity to identify factors of the economic aid from the Western countries, namely the EU and its sectoral distribution. The article proves that the issue of maintaining macroeconomic stability becomes fundamentally important for Ukraine on the back of an increase of its military expenditures, a substantial decrease in budget revenues, the need to maintain a certain level of social expenditures, a significant decrease in export potential and a partial Russian infrastructure blockade. That is why the EU’s financial support for Ukraine looks more important than ever. The article proposes economic-mathematical models based on the regression-correlation method for determining the determinants of EU economic aid to Ukraine. The results of the analysis show that total aid to Ukraine is significantly correlated with the donor country’s trade relations with Ukraine, the presence of a common border with the Russian Federation, and is inversely proportional to the size of the donor country’s economy. Countries with a larger share of migrants from Ukraine are the largest providers of financial aid to Ukraine. Humanitarian aid significantly correlates only with imports to Ukraine. Military aid depends on the size of the donor’s economy and the presence of a common border with the Russian Federation. No evidence was found of the influence of the following indicators on aid to Ukraine: direct investment in Ukraine, distance from Ukraine, total development aid to the countries of the world. The research allows to conclude that among the EU member states the main donors during the Russian-Ukrainian war were Germany, Poland and France and in relative terms – the Baltic states and Poland. The future development of the Ukrainian economy and foreign trade in general and in particular with EU member states will largely depend on the restoration of the country’s destroyed export structure and access to the seas.

The grain industry occupies a leading position in the domestic agricultural market, and today, under the conditions of the 2022 war, the effective functioning of the grain market is extremely important to solve the problem of ensuring food and national security not only in Ukraine, but also in many other countries of the world. The purpose of the research is to conduct a correlation-regression analysis of the profitability of grain production in Ukraine, to single out the main influencing factors, to build a linear regression model based on the factors identified. Previous studies devoted to this topic (conducted by scientists from Ukraine, Great Britain, Egypt, Bangladesh, Iran, Niger, Nigeria, Zimbabwe and China) cover a wide range of factors influencing the profitability of grain production. However, the authors assume that to the greatest extent the studied indicator is influenced by precisely those factors that come from the essence of the definition of the profitability indicator. In order to test this hypothesis, the method of correlation-regression analysis was used, which allowed to identify factors that significantly impact the profitability of grain production in Ukraine. Model building and calculation of the regression coefficients were conducted using the software package STATISTICA. It was found that the most significant variables are yield, sales prices, costs of production and sales, on the basis of which a linear regression model was built, that reflects the dependence of the profitability of grain production in Ukraine on the above-mentioned indicators ( ). With an increase in yield per unit, profitability increases by 1.27 units. With an increase in the selling price per unit, the profitability increases by 0.0242. If the cost per unit of production increases, then the profitability of cereals will decrease by 0.0007. The distribution of the residuals of the model obtained by the authors is close to the normal distribution, and the histogram of the distribution of residuals is close to the graph of the normal distribution, therefore, we can conclude that this model is adequate. Based on the analysis of the distribution of residues, the model can be considered satisfactory. The analysis revealed a negative scale effect in the grain industry, which can be avoided if agricultural land is used effectively. The cancellation of the moratorium on the sale of land opens the way for the transfer of land to more efficient users, which will have a positive effect on the profitability of production.

The article is devoted to solving the problem of improving the efficiency of the adaptive management system of an agricultural enterprise on the basis of controlling. The necessity of introducing a management system aimed at ensuring a phased management of enterprise processes, taking into account the specifics of functioning with a high level of efficiency, flexibility and efficiency, has been substantiated. A retrospective analysis of the formation and development of the control system in industrialized countries has bee carried out. The results of the analysis made it possible to highlight the main concepts of controlling in accordance with their orientation. The peculiarities of the organization of the controlling system at agricultural enterprises of Ukraine in the conditions of seasonal market fluctuations have beenare determined. Growing crops, unlike the production of products in other industries, has such a feature as seasonality. The seasonal nature of production of agricultural enterprises determines the parameters of the activities of industries that produce and maintain agricultural products, harvest, preserve, process and sell agricultural products. Seasonal fluctuations have a direct impact on the intensity of the use of financial, material and technical, labor, energy and other types of resources of agricultural enterprises in certain periods of time during the calendar year. Thus, they impede the effective planning of the financial and economic activities of agricultural enterprises. This requires the improvement of the management system of an agricultural enterprise based on controlling to balance financial flows between all links of the agroindustrial complex. A mathematical model describing time parameters has been presented. Within the framework of the presented model, controlling actions aimed at ensuring the basic conditions for the functioning of an agricultural enterprise and preventing the phenomenon of shortage of funds during the “low” market period have been proposed. The basis for the construction of the model is the structure and objective proportions that determine the ratio between monetary funds and flows of funds of the enterprise of certain periods of its production and sales activities in the short term. The model allows timely detection of problems and making appropriate corrections in management decisions in order to minimize the destabilizing influence of environmental factors and eliminate unwanted deviations. Controlling actions are formed in the form of reports for the purpose of further use in the process of implementing the developed business processes.

Published: February 2023

Este trabalho teve como objetivo realizar um levantamento com profissionais que lidam diretamente com pescado (pescadores e peixeiros) sobre a percepção deles em relação à ocorrência de parasitos nos peixes marinhos comercializados em Piúma, ES. Foram entrevistados 49 participantes (30 pescadores e 19 peixeiros), dos quais 75% disseram já ter visto algum tipo de parasito em peixes, sendo que 21% relataram ter observado endoparasitos, 33% ectoparasitos e 46% ambos os tipos. Os sítios de parasitismo mais relatados foram: brânquias, cavidade celomática, pele, intestinos, musculatura, olhos e cabeça. Os principais peixes citados como hospedeiros de parasitos foram: corvina (Micropogonias sp.), cação caçonete (Rhizoprionodonporosus), peroá-branca/peixe-porco (Balistes capriscus), xaréu (Caranx lugubris) e dourado (Coryphaena hippurus). Os parasitos mais frequentemente observados foram ectoparasitos, que são mais fáceis de serem percebidos, em função do seu tamanho e localização do hospedeiro. Os ectoparasitos mais observados pelos entrevistados foram os crustáceos pertencentes aos gêneros Eurydice, Nerocila e Rocinela. Os entrevistados detinham algum conhecimento empírico que os possibilitou reconhecer que o parasitismo é algo comum e frequente no pescado. Porém, com relação às zoonoses que podem ser causadas por parasitos, eles desconheciam o assunto, o que é preocupante do ponto de vista da saúde pública.

Published: February 2023

O objetivo deste estudo foi testar a viabilidade de agentes curtentes vegetais em peles de pescado de água doce para elaboração de couro de peixe em três municípios da Baixada Maranhense. Foram realizados treinamentos e oficinas sobre Boas Práticas de Manipulação (BPM) de pescado e aproveitamento de resíduos com a produção de couro de peixe. Foram utilizadas peles de tambatinga e tambacu, submetidas ao processo de curtimento utilizando como fonte de tanino vegetal a romã (Punica granatum L.) e aroeira (Schinus terebinthifolius). A análise de coloração do couro foi realizada através da leitura dos padrões de cromas RGB (Red, Green, Blue) por registro fotográfico com imagens de alta nitidez e avaliada pelo Software de edição de cores Paint. A análise da variação de coloração do couro de peixe curtumizado obteve um nível de significância de p < 0,05. O treinamento sobre BPM e as oficinas para a produção do couro de peixe despertaram grande interesse nas comunidades, e a utilização de romã e aroeira como agentes curtentes foi considerada eficiente ao converter a pele em couro, transformando-a em um produto estável e imputrescível, e o desenho exótico formado pelas lamélulas foi mantido. Os couros obtidos apresentaram coloração diferenciada entre o vermelho e o verde, podendo ser utilizados em peças artesanais. O curtimento tem grande importância ambiental, social e internacional, diminuindo a geração de resíduos, obtendo um produto de baixo custo e podendo ser comercializado e agregado valor à renda familiar.

Published: February 2023

A espécie Laeonereis acuta é um nereidídeo detritívoro encontrado em regiões estuarinas com sedimentos arenolodosos. Ocorre na costa atlântica do continente americano, desde Recife (Brasil) até a península de Valdez (Argentina). Além do papel ecológico, os poliquetas são utilizados em estudos ecotoxicológigos, como iscas na pesca e como alimento de organismos aquáticos. Nesse sentido, o objetivo foi analisar o perfil nutricional do poliqueta L. acuta coletado em ambiente natural e avaliar seu potencial como alimento na aquicultura. A coleta das amostras de poliquetas (200 g) foi realizada em regiões entremarés da Lagoa Santo Antônio dos Anjos, em Laguna (Santa Catarina, Brasil), entre os meses de fevereiro e junho de 2018. A composição centesimal da L. acuta demonstrou uma porcentagem de proteína (67,5%) superior ao encontrado em diversas espécies de poliquetas. Com relação aos lipídeos totais, a porcentagem de 6,6% do presente estudo foi similar aos valores mínimos (6,6%) encontrados em estudos com poliqueta selvagem. No entanto, ainda são necessários mais estudos a respeito do perfil nutricional de diferentes populações dessa espécie e em outras condições ambientais. De modo geral, recomenda-se utilizar a L. acuta como uma fonte complementar a uma dieta equilibrada, visando atender os requisitos nutricionais de espécies aquícolas.

Published: February 2023

The aim of the research was to compare the yields of house fly larvae using different proportions of wheat bran and swine feces as larval development medium, in a randomized block experimental design with five replications: A-100 % wheat bran; B- 50% wheat bran and 50% swine feces; C- 100% swine feces. Measurements of the temperature of the substrates, as well as the temperature and relative humidity of the place where the flies were developing were made every 24 hours. The larval yield per m2 and kg of substrate, (including the water used to moisten the larval media) were also registered. The wheat bran substrate presented the highest temperature values (36.78 oC), with values above the ambient temperature. The relative humidity varied between 44 and 68%. The amount of water used per square meter was 28.75; 27.72 and 28.87 L for A, B and C treatments, respectively. The highest yield for all substrates was obtained during the first harvest after six days with the highest values for treatment B with 2869.11 g m²-1 and 181.16 g kg-1, respectively. The transformation of the crude protein of the substrates by the fly larvae was between 28.0 and 41.0%, with the highest value for treatment B with 2869,11 g m² -1  and 181,16 g kg2-1 . No presence of pathogenic agents was observed in the harvested larvae.

Three corn genotypes (hard, semi-hard and semindented) ground in a 10 mm diameter sieve and separated into four particle sizes (greater than 1400 µm; between 1400 and 850 µm; between 850 and 420 µm; and smaller than 420 µm) were evaluated. Starch degradation was verified after incubations in the rumen of cattle, at times of 3, 6, 9, 15, 24 and 48 hours. Corn genotypes with lower vitreousness showed higher solubility, rumen passage rate and rumen degradation. Genotypes in smaller particles showed higher degradations than larger particles. Corn with low vitreousness associated with finer grinding showed better ruminal starch fermentation.
Secure Cloud-based IoT Water Quality Gathering for Analysis and Visualization
Authors: Traore Soin Abdoul Kassif Baba , Valero Maria , Gruss Amy
Published: February 2023

Water quality refers to measurable water characteristics, including chemical, biological, physical, and radiological characteristics usually relative to human needs. Dumping waste and untreated sewage is the reason for water pollution and several diseases to the living hood. The quality of water can also have a significant impact on animals and plant ecosystems. Therefore, keeping track of water quality is a substantial national interest. Much research has been done for measuring water quality using sensors to prevent water pollution. In summary, those systems are built based on online and reagent-free water monitoring SCADA systems in wired networks. However, centralized servers, transmission protocols, and data access can present challenges and disadvantages for those systems. This paper proposes a secure Cloud-based IoT water quality gathering architecture for water quality analysis and visualization to address the limitations of the current systems. The proposed architecture will send, analyze and visualize water quality data in the Cloud by utilizing specialized sensors and IoT-based gateways to capture water measurements (Dioxygen concentration, and temperature, among others). Then, they communicate securely to the Cloud-based server through a high-speed wireless network. We evaluated the performance of the proposed framework on a process-oriented approach to success metrics for cyberinfrastructures. The experiments were conducted in a laboratory and focused on network security and resiliency, the IoT prototype performance in dropping real-time data transmission, and remote access. The results demonstrate higher data collection and transmission effectiveness with minimal data loss and low energy usage over time. The accompanying cloud-based platform provided the flexibility needed for water quality monitoring and laboratory studies.
Social Media Platforms and Responsibility for Disinformation

Researchers are paying closer attention to the rise of disinformation on social media platforms and what responsibility, if any, the companies that control these platforms have for false information being spread on their websites. In this paper, we highlight the recent growth in concern regarding online disinformation, discuss other works regarding the use of social media as a tool for spreading disinformation, and discuss how coordinated disinformation campaigns on social media platforms are used to spread propaganda and lies about current political events. We also evaluate the reactions of social media platforms in combatting disinformation and the difficulty in policing it. Finally, we argue the point that governments should not have the power to regulate the content of social media platforms except in cases where said content is actively illegal or could be categorized as a type of speech that is not protected by the First Amendment.

Authors: Tozetto David José Oliveira , Botelho Nara Macedo
Published: February 2023

O ensino médico, após inúmeras mudanças, tem, hoje, o aluno como sujeito ativo na construção do raciocínio clínico, do diagnóstico assertivo e das condutas adequadas. Assim, este trabalho tem como questão norteadora: de que forma a simulação realística em urgência e emergência pode contribuir para identificar as principais dificuldades de aprendizado dos alunos de um curso de medicina? O objetivo deste trabalho está pautado em identificar dificuldades de aprendizado dos alunos de um curso de medicina durante treinamento em atendimentos simulados em situações de urgência e emergência. Sobre a metodologia, trata-se de um estudo transversal, descritivo, com abordagem qualitativa, com amostra constituída por 29 alunos matriculados na disciplina de Urgência e Emergência em Clínica Médica do internato do curso de Medicina de Marabá da Universidade do Estado do Pará (UEPA). Foram realizados treinamento teórico e estações de simulação realística em atendimentos de pacientes em Parada Cardiorrespiratória (PCR), Dor Torácica Aguda (DTA) e Acidente Vascular Encefálico (AVE), com gravações e sessões de debriefing após cada estação prática. Para a coleta de dados, foram utilizados questionários/checklists de avaliação para cada sessão/atendimento, respondidos pelos alunos e pelo professor/avaliador nas 3 situações citadas (PCR/DTA/AVE). Os estudantes também puderam fazer sugestões para melhorar o treinamento simulado nos questionários por eles respondidos. Os dados coletados mostraram uma avaliação positiva do método por parte dos alunos, e o melhor desempenho dos participantes ocorreu nas sessões de treinamento sobre atendimento à PCR (72% dos alunos acertaram mais que 80% das questões) e à AVE (75% dos alunos acertaram mais que 80% das questões). Entre as dificuldades encontradas estão a falta de checklists em locais de fácil visualização durante os atendimentos, a falta de elaboração dos resumos (“flashcards”) para consulta rápida em cada cenário específico, a não utilização de simulação com pacientes atores (podendo-se utilizar, inclusive, os próprios alunos nesses papéis) e a necessidade de maior diversificação dos casos clínicos. Essas sugestões foram importantes, e seriam de fácil implementação durante os cenários citados neste trabalho. Como conclusão, foi possível observar que a simulação realística em urgência e emergência deve ter um lugar de destaque no treinamento de estudantes de medicina. Ressalta-se, porém, que dificuldades são encontradas, e as sugestões e o constante feedback de quem está sendo treinado torna-se muito importante para o aprimoramento contínuo deste método.

Завданням дослідження є розвиток та удосконалення методичних підходів до формування системи управління структурою капіталу підприємства в системі фінансового менеджменту з урахуванням впливу факторів зовнішнього середовища для забезпечення стабільного функціонування та сталого розвитку підприємства. В роботі доведено, що ефективно функціонуюча система управління структурою капіталу підприємства є однією з ключових, оскільки забезпечує підвищення рентабельності власного капіталу з одночасним забезпеченням фінансової стійкості підприємства. Встановлено, що особливим елементом в системі управління структурою джерел фінансування активів підприємства належить аналізу ситуації на конкурентному ринку та доведено необхідність проведення оцінки впливу факторів макросередовища на систему управління структурою капіталу підприємства. Для оцінки впливу факторів макросередовища автором запропоновано використання факторного аналізу, який дозволяє визначити стійкі закономірності та обґрунтувати вплив обраних факторів на систему управління структурою капіталу підприємства.

A QUESTÃO NACIONAL ANTE O ELÃ PÓS-MODERNO: CAPITALISMO DEPENDENTE, SUPEREXPLORAÇÃO DA FORÇA DE TRABALHO E LUTA DE CLASSES NO BRASIL
Authors: Oliveira André Luis Amorim , Santos Thiago Araújo
Published: February 2023

Resumo: O estudo da questão nacional articula uma dupla perspectiva. Por um lado, envolve o diagnóstico sobre o caráter do desenvolvimento capitalista numa dada formação econômico-social; e, por outro, associa-se ao projeto estratégico de superação do capitalismo (ou acomodação neste) com base no diagnóstico assumido. Neste artigo, retomamos criticamente o tema à luz da Teoria Marxista da Dependência (TMD), posicionando a luta de classes e a superexploração da força de trabalho no Brasil como eixos de análise. O estudo foi realizado por meio de coleta e análise documental de notícias sobre reivindicações salariais e por melhores condições de trabalho no setor da silvicultura em Três Lagoas-MS. A natureza e recorrência das reivindicações, ainda que episódicas e fragmentárias, sugerem que a “velha” contradição de classes segue vigente no capitalismo dependente brasileiro.  Palavras-chave: questão nacional; capitalismo dependente; superexploração da força de trabalho; Três Lagoas.
Turkey’s Syrian Refugees Dilemma between the Triangle of Violence
Authors: Şahin Devrim , Kocadayı Safiye
Published: February 2023

This paper studies the worsening relations between the Syrian refugees and the citizens of Turkey and argues that the current state of relations can be understood as an example of the renowned pacifist Johann Galtung’s negative peace concept. While no military dispute exists in Turkey, the relationship between refugees and the people of Turkey lacks the behaviour, institutions, and organizations sine qua non (essential) to make and survive the peace that Galtung identifies as positive peace. Turkey is not a kind of advanced democracy with cosmopolitan culture. Maintaining this kind of all-embracing peace in Turkey requires a comprehensive settlement including efforts to get the international community to be involved more, avoiding political rhetoric that securitizes the issue, furthering training and education programs for the orientation of the refugees, clarifying the statute of the refugees and preparing the ground for the return of refugees to their country, if possible.
