Prediction of Petrophysical Properties using Post Stack Seismic Inversion and Geostatistical Techniques over F-3 Block, Netherlands - A Comparative Study
Authors: Kushwaha Prabodh K. , Singh Raghav , Maurya Satya P. , Rai Piyush
Published: September 2023

To estimate petrophysical parameters, seismic inversion techniques have been frequently used for estimating attributes like P-impedance, elastic impedance, S-impedance, density, Vp / Vs ratio, and gamma-ray logs from seismic and well-log data. These characteristics enable us to comprehend subsurface lithology for geo-seismic analysis, including its extent and shape. Four different post-stack inversion techniques, including bandlimited inversion (BLI), colored inversion (CI), maximum likelihood sparse spike inversion (MLSSI), and model-based inversion (MBI), have been applied to the post-stack seismic data from the F3 block in the Netherlands in this study. The objective is to compare the efficacy of these inversion methods over F3 block seismic data. For post-stack inversion, the data was inverted into a very high-resolution P-impedance volume. The analysis depicts that all four inversion methods provide mutually consistent subsurface information with marginally better MBI results. Furthermore, geostatistical techniques have been used intensively for further testifying the results obtained from post-stack inversion methods. The geostatistical techniques use seismic data-derived attributes and inverted impedance-derived attributes as input to estimate P-wave velocity, porosity, and density away from the boreholes. Two geostatistical methods namely probabilistic neural network (PNN) and multilayer feed-forward neural network (MLFN) are used for the analysis. Porosity, density, and P-wave velocity have been predicted using both techniques which highlighted different characteristics of the subsurface with very detailed information. The derived results show that reservoir properties have been better estimated with the combination of MBI and PNN techniques for F3 block data over the other methods used in this study.
test de Turing y la filosofía de la inteligencia artificial
Authors: Ríos Rubén H.
Published: September 2023

Este artículo, en términos generales, es una respuesta a la pregunta que formula Alan Turing en un célebre artículo de 1950 acerca de si las máquinas digitales piensan. Con lo que se suma, en el marco de lo que se ha denominado “dataísmo”, a uno de los debates centrales de la filosofía de la inteligencia artificial. De allí que revisa sumariamente la historia de esta última, en la cual el momento de la cibernética adquiere cierto valor de hito, así como los aportes de Turing en la concepción de lo computable y la relación del test que propuso con el razonamiento algorítmico.
reciprocidad al centro: economía y Antropoceno desde el Económico de Jenofonte

Este artículo examina cómo, en el Económico, Jenofonte pone la reciprocidad en el centro de las relaciones económicas entre los seres humanos y la Tierra, y entre los seres humanos mismos en sus intercambios. Invita a reflexionar sobre un modelo económico que permita hacer del planeta no un mero recurso, sino el lugar de una forma de justicia global.
Platón frente al comercio marítimo. Elementos para una interpretación del Antropoceno
Authors: Montoya María Del Pilar
Published: September 2023

A través del estudio de algunos pasajes que Platón consagra al análisis de las repercusiones psicológicas, políticas y económicas de las actividades en torno a las cuales gira la economía de las ciudades empíricas, pretendemos mostrar que el pensamiento económico de Platón, fundamentalmente sus consideraciones sobre el comercio de importación y exportación que se realiza por vía marítima, ofrece elementos de inestimable valor para pensar la relación de las dinámicas de consumo y de producción promovidas por la globalización con la actitud del ser humano frente a la Tierra y las consecuencias que sedesprenden de ella.
«El mundo es un animal perfecto». Política y biología en los estoicos
Authors: Nava Contreras Mariano
Published: September 2023

Este estudio intenta revisar la concepción estoica del universo como un inmenso animal sensible provisto de pensamiento y perfecto en grado sumo, tal y como se encuentra formulada por Sexto Empírico en Adv. Math. IX 88 = SVF I 529. Esta idea hunde sus raíces en el biologicismo y el naturalismo aristotélico, si bien fueron los estoicos los que la desarrollaron como parte de su pensamiento político, con importantes connotaciones no sólo para la política y la biología, sino también para su sistema ético, físico y cosmológico. Esta concepción constituye uno de los primeros intentos de establecer una relación entre políticay biología en el pensamiento griego.

Sobre derechos humanos en el pensamiento de Helio Gallardo: praxis de liberación, tramas sociales y multi-garantías
Authors: Sánchez Rubio David
Published: September 2023

En este trabajo se analizan algunos de los aportes del pensamiento de Helio Gallardo en materia de derechos humanos.Partiendo del problema fundamental que presentan los derechos humanos, referido a la distancia y el abismo que existe entre sus discursos, sus teorías y sus prácticas, entre lo que se dice y lo que se hace, se reflexiona sobre su propuesta socia-materialista basada en los procesos de lucha y las experiencias de contrastes de las organizaciones sociales modernas y sus movimientos sociales frente a las deficiencias y los sistemas de dominación del orden burgués y capitalista.

Tras una descripción de sus análisis de las luchas sociales y la praxis de liberación, se propone un sistema multi-garantista de derechos humanos que gira en torno a las prácticas y acciones individuales y colectivas que despliegan una realidad de los mismos basados en una cultura que los concibe multidimensionalmente a tiempo completo y en todo lugar.
The “School Meals Market” in Hungary — Typical Characteristics of Demand and Supply
Authors: Kelemen Katalin
Published: September 2023

The present study examines the Hungarian practice of public catering for children from an economic perspective, bearing in mind that the production and consumption of food is, at the same time, an economic activity. Taking this approach, we focus on which institutions contribute to or hinder efficiency, by which we mean the efforts of economic agents to generate maximum welfare from the available (meager) resources. For social reasons, the supply of public catering for children is a statutory obligation on the part of local authorities, where efficiency must be combined with social considerations. The study reviews the rationing mechanism of school meals catering as a public service, looking first at the main factors determining the level of demand for public catering for children, and then at the main factors that influence supply.
Wybrane zagadnienia handlu ludźmi i zagrożonymi gatunkami roślin i zwierząt
Authors:   Uniwersytet RzeszowskiJoanna, Uliasz Joanna ,   Uniwersytet Rzeszowski
Published: September 2023

Handel ludźmi oraz zagrożonymi gatunkami roślin i zwierząt to zjawisko znane od zarania dziejów. Wydawać by się mogło, że należy już wyłącznie do zamierzchłej przeszłości. Nic bardziej mylnego. Ta niechlubna karta historii ma swoją współczesną smutną kontynuację. Według dostępnych statystyk handel ludźmi stanowi jedno z najpoważniejszych zagrożeń XXI wieku. Pod względem wielkości dochodów ten nielegalny biznes zajmuje trzecie miejsce zaraz po handlu bronią i narkotykami, generując zysk w wysokości 32 mld dolarów rocznie. Zdecydowana większość osób, które padają ofiarą wspomnianego procederu, jest zmuszana do prostytucji bądź pracy przymusowej. W ciągu ostatniej dekady zmieniło się tylko jedno – statystyka ta niestety nieubłaganie wzrosła. W dużej mierze zjawiska, o których mowa w książce, są wynikiem dynamiki stosunków społecznych, globalizacji i możliwości właściwie nieskrępowanego przemieszczania się, co sprawia, że w dzisiejszym świecie migracja zarobkowa jest zjawiskiem powszechnym i jako taka niejednokrotnie kończy się handlem ludźmi i pracą niewolniczą. Inną kwestią, o której nie można zapominać, jest fakt, że w niektórych rejonach świata, w tym Ameryce Południowej, w Afryce czy Azji, zjawisko handlu ludźmi jest społecznie akceptowane i wręcz naturalne. Świat przestępczy, upatrując w handlu ludźmi źródła potężnych zysków, działa niezwykle prężnie i niestety skutecznie. W procederze handlu ludźmi biorą udział doskonale zorganizowane i wyspecjalizowane grupy przestępcze, których obszar aktywności obejmuje kilkadziesiąt krajów. To niewątpliwe wpływa na skalę zjawiska. Podobnie wygląda sytuacja w przypadku handlu zagrożonymi gatunkami. Swoista moda na hodowlę egzotycznych roślin czy zwierząt, organizowanie polowań na rzadkie zwierzęta dla zdobycia trofeów czy w celu produkcji medykamentów z nich sprawia, że liczba przestępstw w tym obszarze wzrasta, co powoduje, że wiele gatunków roślin i zwierząt jest zagrożonych wyginięciem lub ginie. Te złożone, niezwykle ważne, ale i dynamicznie zmieniające się zjawiska dały impuls do rozważań prowadzonych na kartach niniejszej książki. Problem handlu ludźmi i zagrożonymi gatunkami roślin i zwierząt ujęty został w szerokiej, różnorodnej perspektywie zaprezentowanej przez autorów opracowania, co stanowi o wartości lektury.

Nowadays, human trafficking is considered to be a modern form of slavery. Even though many laws were adopted, the problem is still challenging to eliminte. Practically everyone can become a victim of this crime. This applies especially to the minors. International law includes regulations that concern specific definition of this term and the protection of victims. If the matter is defined correctly there is a foundation to create a detailed regulation. Then it is easier to convict the offender on the basis of human trafficing. Some problems occur when the victim of human trafficing becomes a criminal. It happens due to special circumtances, when the person acts under duress. The European Parliament and the Council of the European Union adopted a directive on preventing and combating trafficking in human beings and protecting its victims. According to its article 8, competent national authorities are entitled not to prosecute or impose penalties on victims of trafficking in human beings for their involvement in criminal activities which they have been compelled to commit as a direct consequence of being subjected to any of the acts referred to in Article 2 (of this directive). However, the situation is completely different in the US law system. It has been a common practice to treat minors involved in prostitution as offenders. Discussion around a couple of cases led politicians to pass the law that treats these minors as victims, not criminals. Implemented solutions improve their situation indeed.

This paper analyzes the impact of non-compliance on distribution of government support to SMMEs in the King Cetshwayo district in South Africa during the Covid 19 lockdown. We use qualitative data from semi-structured interviews and thematic content analysis to analyze the experiences and perceptions of government employees and political representatives who were involved in distributing the goods or services. Our findings show that compliance and negative attitudes towards compliance requirements were a hindrance to government interventions to ameliorate the Covid 19 pandemic induced recession. The top-down structure of the compliance system also contributed to challenges as local, national, and regional regulators were not coordinated with each other. We therefore recommend alignment of compliance requirements across the distinct levels of government (regulators), and improvement in efficiency of the regulatory system. A complete online system can be used and made accessible to local regulators to improve service delivery. In addition, compliance requirements can be relaxed during times of crises to enable access to government support by SMMEs.
xecutive Pay Cuts during Covid: Yielding to Pressure or Potential for Real Change?
Authors:   AFG College with the University of Aberdeen, Qatar, Meier Florian
Published: September 2023

Executive compensation has been the subject of longstanding criticisms for possibly setting wrong incentives or for being excessive. In the Covid pandemic in 2020/2021, numerous CEOs worldwide decided to temporarily forgo part of their compensation in response to calls for solidarity with stakeholders who had to make financial or other sacrifices. While there have been suggestions that these concessions might be the starting point for wider reforms of executive compensation to address some of the criticisms, pay has quickly returned to pre-Covid levels and reached new record highs. This article examines whether the executive pay concessions made during Covid should be considered a temporary phenomenon, or whether they might indeed have the potential to start a larger process of reassessing and reforming executive compensation. The analysis explored three angles: First, the cuts to compensation themselves were examined to understand the type of compensation affected and their magnitude. Second, reasons and pressures that led firms to adjust pay during the onset of the crisis were explored, and whether they can be considered temporary or more fundamental. Third, the theoretical angle used legitimacy theory, institutional theory, and resource dependence theory to assess the intention and longevity of measures undertaken. Taken together, the analysis suggests the actions on pay were a temporary reaction to a specific situation, and do not seem to be intended nor contain potential for longer lasting, widespread changes.
Enhancing Foreign Currency Allocation for Private Sector Development – Case of the Reserve Bank of Zimbabwe Forex Auction System
Authors:   North-West University, South Africa, Pasara Michael Takudzwa , Nyajeka Nigel ,   George Washington University, USA, Dunga Steven Henry ,   North-West University, South Africa
Published: September 2023

Foreign currency shortages remain a perennial challenge in Zimbabwe leading to several spillover effects such as shortages in electricity, raw materials, fuel, inflation among other market distortions. The central bank introduced the Dutch Auction system in an attempt to address forex shortages but the effectiveness of this approach has been questioned. This study employed the Vector Autoregressive (VAR) and error corrected (VECM) models in order to empirically determine how the Reserve Bank of Zimbabwe can efficiently allocate foreign currency in a manner which supports private sector development. In the short run, the auction is an effective tool to promote private sector development. However, long run analysis presents a deletions effect. This is due to a rise in round-tripping from market participants to leverage and perform arbitrage on different rates (auction and parallel), increased backlog reflecting shortages in allotments and high incidences of corruption. All this leads to a significant decrease in the confidence levels of the economy among private stakeholders. The study recommends monitoring of authorized auction dealers, improve public confidence by minimizing rent-seeking behavior, re-model exporters participation in the auction system or abandoning the auction system altogether.
Gymnasieelevers erfarenheter av särskilt stöd
Authors: Öhman Anna
Published: September 2023

Vad har stödinsatser för betydelse ur elevers perspektiv? Den här artikeln utgår från en intervjustudie med gymnasieelever om deras erfarenheter av särskilt stöd. Delar av det empiriska materialet har analyserats utifrån en narrativ ansats och teoretiska perspektiv kopplade till makt och identitet. Föreställningar om och innebörd av särskilda behov är komplexa och mångdimensionella. Ur analysen av två elevers berättelser framträder relationella aspekter som trygghet och delaktighet som betydelsefulla för eleverna. Analysen ger också en bild av hur särskilda behov och särskilt stöd är inbäddade i olika former för maktstrukturer där erfarenheter av att vara inkluderad eller exkluderad skapar olika identiteter. Vikten av att bemöta varje elev i behov av särskilt stöd som en unik individ är central i berättelserna. En slutsats som kan dras från resultaten är att en pedagogik som både är relationell och kunskapsutvecklande visar sig vara viktigt för elever i behov av särskilt stöd. Det konceptualiseras med det reciproka begreppsparet tillhörighet och tillblivelse, där inkludering förstås som något långt mer än skolplacering.
Praktikutvecklande samtal på vetenskaplig grund
Authors: Gradén Mattias , Irisdotter Aldenmyr Sara
Published: September 2023

Enligt Skollagen ska skolans verksamhet vila på vetenskaplig grund. I denna studie intresserar vi oss för hur verksamma lärare läser och tolkar befintlig forskning. En utvecklingsgrupp på en skola, bestående av tre lärare och två skolledare, samlades utifrån sitt uppdrag att driva skolutveckling på sin egen skola. Vi valde som forskare ut fem olika vetenskapliga texter på temat skolutveckling, och observerade de samtal som utvecklingsgruppen förde sinsemellan runt dessa fem texter, i förhållande till deras egna utmaningar. Det huvudsakliga syftet med studien är att bidra med fördjupad kunskap om mötet mellan lärares praktik och olika typer av innehåll i vetenskapligt texter. För att uppnå detta syfte utarbetar vi en metod för att identifiera intertextuella möten mellan forskningstext och erfarenheter från skolpraktik, det vill säga tillfällen då komponenter ur forskningstext möter praktikförankrade referenser i samtal. Vi intresserar oss särskilt för potential till praktikutveckling på vetenskaplig grund. Resultatet visar att den vanligast förekommande intertextuella aktiviteten var att deltagarna tog fasta på texternas framskrivna resultat och lät dessa berika deras eget professionsspråk. Ett berikat professionsspråk är den praktikorienterade samtalsaktivitet som är mest framträdande i alla samtal. Deltagarna använder nya begrepp eller får fördjupad förståelse för sådant som de redan har erfarenheter av.
Liberalization of Сurrency Regulation in Russia in the Context of Sanctions
Authors:   Financial Research Institute of the Ministry of Finance of the Russian Federation, Ershov Dmitry
Published: September 2023

The purpose of the work is to analyze the transformation of the regime of monetary and financial regulation in Russia in the context of international sanctions in 2022. The course towards the liberalization of foreign exchange regulation in Russia has been temporarily changed in order to reduce capital outflow, protect the interests of Russian companies, and maintain the stability of the monetary and financial systems. The main measure was a temporary return to the requirements for the repatriation of foreign exchange earnings by exporters. After the measures took effect, the process of gradual abandonment of the imposed restrictions began. It is concluded that with the abolition of the requirement for the repatriation of foreign exchange earnings, the previously taken course towards the liberalization of foreign exchange regulation has generally recovered and is being maintained despite an unfavorable change in foreign economic and foreign policy conditions. Since the decisions on the introduction of currency restrictions and subsequent decisions on their abolition were taken as temporary measures, they need to be legislated. An analysis of some possible ways of further developing the liberalization of foreign exchange regulation in Russia is presented. It can be aimed at reducing the overall regulatory burden on businesses, promoting the development of non-commodity exports, de-dollarizing trade and investment, reorienting to the most promising foreign economic partners, and expanding international cooperation within the Multilateral Competent Authority Agreement on Automatic Exchange of Financial Account Information.
Financial Break-Even Point and Indicator of Devaluation of Own Capital of Agro-Industrial Complex Enterprises
Authors:   Volgograd State Agricultural University, Morhachov Illia
Published: September 2023

The agro-industrial complex of the Russian Federation occupies a special place in ensuring the food security of the country, which makes it relevant to study the issues of a real increase in the equity capital of the relevant enterprises. As an indicator of its depreciation, the indicator of return on equity is considered, the value of which must be compared with the parameters of factors that reduce the real value of such capital: inflation, devaluation of the national currency, opportunity costs (losses) from choosing the worst use case, and income tax at a conditionally zero level of real profitability. The financial break-even point is proposed to be considered as such a volume of activity in which the value of return on equity shows the feasibility of business, taking into account inflation and devaluation of the national currency, as well as possible alternatives for the use of capital. The impossibility of achieving it in the long term makes investment in the business inappropriate. It has been determined that over the past 22 years, the average statistical losses from inflation and income tax at a conditionally zero real level of return on equity corresponded to a value of 11.69%. To ensure the preservation of the real value of such capital, its profitability at the enterprises of the agro-industrial complex had to exceed the specified value. Over the specified period of time, the inflation rate in the country exceeded the rate of devaluation of the national currency, which makes it possible to use inflation as a benchmark for the depreciation of equity capital. An analysis of the actual value of the return on equity for the period 2017–2021 for agribusiness enterprises showed that, in general, this indicator exceeded the value of 11.69%. Thus, over a long period of time, the main activity of enterprises in the agro-industrial complex provided their owners with a real increase in capital. It is possible that such a level of profitability was provided at the expense of financial state assistance to the considered sector.

Authors:   Volgograd State University, Ivanov Alexey , Klenova Tatiana ,   Volgograd State University, Koneva Daria ,   Volgograd State University
Published: September 2023

The article examines the current conditions for the formation and implementation of industrial policy in the Russian economy and the experience of European countries in modernizing the goals, as well as the instruments of industrial policy in the context of increasing crisis trends. Attention is focused on changes in specific economic and institutional conditions for the implementation of industrial policy and on the impact of structural, financial, and political shocks on the choice of its goals and priorities at the meso- and macro-levels. There is a great role of variability and inconsistency among factors influencing industrial policy: environmental, energy, infrastructural, and institutional. The experience of foreign countries in the resuscitation of industrial structures is considered. The necessity of choosing the goals and mechanisms of industrial development with maximum reference to internal resources, creating closed value chains, choosing an acceptable balance between infrastructure development and solving the problems of ensuring national economic security, and overcoming the trends of capital leaching from industrial sectors is emphasized. The high importance of the state’s influence on the corporate policy of the largest companies, increasing the role of the state in financing investments, and strengthening the economic sovereignty of the country are pointed out. The importance of applying new mechanisms for adaptation of the domestic industrial complex to new, changing political and economic conditions of development is emphasized.
Features of operational risk management
Authors: Indarbaev Shamilʹ , Kapustina Nadezhda
Published: September 2023

In this paper, the author considers aspects of operational risk management, which are understood as the process of identifying, assessing, managing and controlling operational risks in an organization. It includes the development of policies, procedures and controls that enable an organization to minimize the potential harm from operational risks. One of the key aspects of operational risk management is risk assessment. It allows you to determine the likelihood of operational risks, their potential damage and the resources needed to manage them. Risk assessment can be performed using various methods such as data analysis, risk modeling and expert judgment. Another important aspect of operational risk management is the development and implementation of controls. They allow you to minimize risks and reduce potential damage from operational risks. Control measures may include automated control systems, checks and balances, personnel training and other measures. In addition, the author notes that operational risk management also includes monitoring and analysis of operational risks. It allows the organization to quickly respond to possible problems and take timely action to eliminate them. Monitoring and analysis of operational risks can be carried out using various tools such as reports, statistics and regular reviews. The author also considers it important that operational risk management should be integrated into the overall risk management strategy of the organization. At the same time, it must be flexible and adaptive in order to respond to changes in the external environment and changes in the organization itself. In general, according to the author, operational risk management is an integral part of risk management in an organization. Its main goal is to minimize potential losses from operational risks in order to ensure the long-term sustainability and success of the organization
Isolation, molecular identification, and in vitro control of Campomanesia rufa (O. Berg) Nied. endogenous bacteria
Authors: Mosqueira Judith Georgette Alcalde , Paiva Renato , Rivas Eliana Borges , Harakava Ricardo , Souza-Dias Maria Aparecida Gomes , Reis Michele Valquíria dos
Published: September 2023

ABSTRACT Campomanesia rufa (O. Berg) Nied. is a Myrtaceae species native to the Brazilian Cerrado. As C. rufa is considered endangered, in vitro propagation is an alternative for its conservation. However, the lack of effective disinfection protocols for endophytic microorganisms naturally present in plant tissues hinders the success of micropropagation. In this context, the objective of this study was to isolate, molecular identify, and control endogenous occurring bacteria of C. rufa propagated in vitro. Purified PCR products of bacterial isolates were sequenced by the Sanger method and aligned with homologous sequences using the Basic Local Alignment Search Tool (BLAST) available in National Centre for Biotechnology Information (NCBI) database. MEGA7 software was used to align all sequences and to draw phylogenetic trees. Survival, shoot height, and efficiency of antibiotics (streptomycin, ampicillin, and chloramphenicol) at different concentrations in the culture medium were evaluated. Different Bacillus sp. strains were observed in the plant tissues. When testing the control of Bacillus sp. with antibiotics, 32 mg L-1 ampicillin caused a significant reduction in bacterial contamination with no effect on explant survival. On the other hand, 256 mg L-1 streptomycin caused the greatest reduction in contamination but was lethal to over 90% of the explants. This study is the first report on the occurrence of endogenous bacteria and their control in the context of in vitro native species conservation.
Hegemonic masculinities as counter resistance in the university context
Authors: BARBOSA ALINE DOS SANTOS , ROMANI-DIAS MARCELLO , BERLATO HELIANI
Published: September 2023

Abstract This study analyzed the facets of the exercise of hegemonic masculinities as a means of counter-resistance of young men in the face of the rise of female groups in the university context. A longitudinal, qualitative, and interpretive study was developed based on multiple data sources, such as interviews, documents, and organizational artifacts, which were analyzed inductively based on open, axial, and selective coding. As main results of the triangulation of the data, the following stand out: (i) hegemonic masculinities are characterized by leadership in student groups, exaltation of masculinity, and classification of women as subordinate to boys’ interests; (ii) there is a resistance of a feminist collective, marked by the fight against situations of machismo in the university context; (iii) there is a male counter-resistance, with the intensification of actions against women, through harassment, aggression, vandalism, and compositions of sexist songs. The article contributes to the discussion about gender and resistance, especially in the organizational context.
Favela venceu! - Resistência veiculada em videoclipes de bregafunk
Authors: SOUZA-LEÃO ANDRÉ LUIZ MARANHÃO DE , LOPES MARIANA ALMEIDA DE SOUZA
Published: September 2023

Resumo A produção musical é responsável pela veiculação de ideologias, uma vez que gêneros se encontram intrinsicamente atrelados a discursos políticos. Na cena musical recifense, o bregafunk cumpre esse papel, retratando, em sua produção de videoclipes, a periferia como um espaço de sociabilidades e afetividades, bem como de ambição por melhores condições sociais e econômicas. Com base na teoria foucaultiana, consideramos a favela um exemplo emblemático de resistência. Com base nisso, a presente investigação se orienta pela seguinte questão de pesquisa: como a produção de videoclipes de bregafunk evidencia uma resistência da favela? Para tal, realizamos uma Análise de Discurso Foucaultiana de 777 videoclipes de bregafunk postados no Youtube entre setembro de 2012 e setembro de 2020. Os resultados evidenciam uma formação discursiva que alude a uma maior representação da favela na sociedade. Por um lado, essa formação discursiva é caracterizada pela busca de empoderamento de minorias e pelo próprio cidadão da periferia; e, por outro, pela valorização da favela. Esses achados evidenciam uma resistência da favela por meio da representação de identidades políticas circunscritas nesse espaço social. Esse processo revela um ethos particular, que, ao ser alternativo e resistente ao status quo, revela uma sublevação, ao sustentar discursos políticos a partir de atos de contra conduta ao que costuma ser considerado socialmente normal.
Gestão social sob o crivo da linguagem do direito na mediação entre mundo-da-vida e sistema
Authors: CAMPOS MARILENE DE SOUZA , PEREIRA JOSÉ ROBERTO
Published: September 2023

Resumo O objetivo deste trabalho é compreender como a linguagem do direito mediatiza as relações entre mundo-da-vida e sistema, fundamentando teoricamente a gestão social ao colocar a sociedade como protagonista das ações públicas. Consideramos, nesse aspecto, a gestão social como manifestação de um interesse público não-estatal no âmbito das relações complexas entre Estado, Mercado e Sociedade, cuja linguagem do direito socializa e integra, faz interagir organizações, instituições e afeta a autonomia pública e privada dos indivíduos. Para solucionar os problemas relativos à tensão entre mundo-da-vida e sistema, Habermas dedicou-se a detalhar sua teoria política juntamente com o direito, articulando republicanismo e liberalismo, autonomia pública e privada, facticidade e validade. O emprego do conceito de gestão social, em sua vertente habermasiana, suscita questões relativas ao direito, as quais receberam pouca atenção dos teóricos, apesar da centralidade que assumiram nas obras do autor. Destacam-se as transformações que a compreensão do direito sofre nas seguintes obras de Habermas: Teoria do agir comunicativo e Direito e democracia. As tensões que ameaçam a solidariedade e o entendimento e que resultam na colonização do mundo-da-vida pelos subsistemas funcionais, o direito transita da condição primeira de juridicialização das relações sociais para a posição mediadora entre o mundo-da-vida e o sistema, de conversão do poder comunicativo em poder administrativo. A gestão social como expressão da tensão e mediação entre mundo-da-vida e sistema é também expressão da tensão entre facticidade e validade do direito, entre autonomia pública e autonomia privada, entre liberalismo e republicanismo.
The process of construction of social values: revisiting the concept of social value from the point of view of the symbolic interactionism tradition
Authors: PIGA TALITA RAVAGNÃ , DOMENICO SILVIA MARCIA RUSSI DE
Published: September 2023

Abstract In the second decade of the 21st century, great issues that challenge humanity, from wars to climate change, have been growing. The consequence of climate change, such as natural disasters, water scarcity, and pandemics, has deepened social inequalities. Many problems have persisted despite the technological, economic and social progress achieved in the last two centuries and make us reflect on how we ended up in this situation. After all, what makes sense and matters to the groups and societies that inhabit this planet? To address this issue, we chose, within American pragmatism, the symbolic interactionism tradition and the concept of social value, based on the sociological approach of social psychology, aiming to explain how the process of construction of this type of value occurs. We revisited, from the three versions of symbolic interactionism (traditional, contemporary, and structural), the concept set forth by Thomas and Znaniecki (1927, 2006). Through this theoretical integration, we propose a contemporary conceptual definition of what social value is in order to continue with the formulation of a theoretical model regarding the process of construction of social values, paving the way to understand the dynamics between the different social structures (macro) and the agency of human beings (micro) in the signification, resignification, and even abandonment of such values.
A new approach to endodontic access in anterior teeth - a pilot study
Authors: FERREIRA Maria Luisa Gomes , MENDONÇA Thamiris , VICTORINO Maria Luiza Zamparoni , SERON Marcelo Augusto , VICTORINO Fausto Rodrigo
Published: September 2023

Abstract Introduction The coronal opening is essential, during endodontic treatment, for direct access to the root canals. Usually, in the anterior teeth, endodontic access is achieved on the palatal/lingual surface, more specifically in the cingulum region. However, the lack of observation for dental positioning can lead to some accidents and complications, such as buccal perforations, causing esthetic damage and compromising the treatment. Objective To evaluate the applicability of a new approach for performing coronal opening in anterior teeth, regarding the wear caused on the tooth crown, and to evaluate the ease of performing the new technique to minimize the risk of perforation. Material and method Ten students (n=10) from the Improvement in Endodontics program participated in the present study. Twenty artificial teeth were used, which were upper, central incisors. Each participant performed two coronal openings. First, with no guidance (Group A - Conventional Technique) and afterward, a new opening, but with guidance with the spherical diamond tip placed parallel to the long axis of the tooth (Group B - Modified Technique). Result The results showed that 90% of the participants considered the Modified Technique as having lower risk of accidents, as well as being easier for locating the pulp chamber. There was a statistical difference both in the measurement of the total area of wear and in the width, while there was no statistical difference in the height. Conclusion Preliminary data collected with the survey were satisfactory for the Modified Technique. Statistically, it showed a favorable difference in relation to the area of wear and the width. However, in height there was no statistical difference.
A dozen fish: some exotic invasive species found in Brazilian waters and their impacts

Published: September 2023

Abstract The introduction of invasive alien species (IAS) is among the leading causes of biodiversity loss in the world. The arrival of these species causes several imbalances in the natural environment. The establishment of these species depends on their transport, entry, adaptive success, and interactions in the environment. This work aims to present 12 species of exotic invasive fish that occur in natural environments in Brazil in the form of a booklet and to discuss some aspects inherent to legislation changes related to the cultivation of these species. The target audience of this study is mainly fish farmers, fishermen, riverside dwellers, assistance technicians, schools, environmental departments, and rural communities. The list had as a criterion the selection of species that are raised in fish farming stations and that already have records of occurrence in natural ecosystems in the country. These are exotic species introduced (from other countries) and with high invasive potential in Brazilian continental waters. To compose the list of these species, national and international studies that discuss the subject were sought, the following species being selected: Ctenopharyngodon idella, Hypophthalmichthys molitrix, Hypophthalmichthys nobilis, Cyprinus carpio, Oreochromis niloticus, Coptodon Rendalli, Oreochromis mossambicus, Oreochromis macrochir, Clarias gariepinus, Ictalurus punctatus, Oncorhynchus mykiss, Micropterus salmoides. In addition to presenting the impacts of invasive alien species on native ichthyofauna, this material will help disseminate technical information and may also be an aid to guide public policy decision making and awareness.
Feminismos interseccionais: problematizando o sujeito do feminismo
Authors: Formiga Giceli Carvalho Batista , Feldens Dinamara Garcia , Arditti Roberta Gusmão
Published: September 2023

RESUMO A compreensão do conceito de interseccionalidade, por vezes, é aprisionada a interpretações identitárias que desconfiguram a sua relevância. Este ensaio pretende apresentar a emergência histórica da noção de interseccionalidade e, para isso, problematiza o conceito de gênero nos estudos feministas desde a abordagem relacional, evidenciando o gênero enquanto categoria, à crítica radical pós-estruturalista, que questiona a substancialidade do gênero e, portanto, evidencia a importância da compreensão interseccional das relações de gênero em seu movimento de produção, de controle e exclusão de subjetividades dissidentes da norma branca cisheteropatriarcal. Sendo assim, destaca-se, neste ensaio, a importância histórica do movimento feminista negro na luta contra os processos de exclusão e silenciamento, propondo uma leitura interseccional e rompendo com a proposta identitária e substancialista do conceito de gênero.

ABSTRACT The Analysis of the Movement of Senses is described as a theoretical and methodological fundamentals for research in education. Initially, the context and the bases are described, to subsequently describe procedures and phases of application of Analysis of the Movement of Senses . In this path, the dialectic perspective, the notions of movement and meaning, always in relation to discourse, are highlighted. For the elaboration of the text, as a kind of metalanguage, the Analysis of the Movement of Senses was applied, producing data through bibliographic research and systematizing them in the meanings that compose the arguments. As every sense is always in motion, the final considerations reiterate the need to understand that, in research in education, there is no absolute end, but a continuous movement of meanings and renewed demands for study.
Conhecimentos da Matemática Incorporada ao Currículo revelados por um grupo de professores
Authors: Soares Marilene Caitano Reis Almeida , Januario Gilberto , Santos Francely Aparecida dos
Published: September 2023

RESUMO O artigo é orientado pelo objetivo de discutir como ideias matemáticas subjacentes aos recursos dos materiais curriculares são percebidas e interpretadas por professores. O quadro teórico remete-se a categorias de conhecimento profissional docente, como o modelo do Conhecimento da Matemática Incorporada ao Currículo para se referir ao conhecimento matemático ativado por professores ao ler e interpretar tarefas matemáticas. Três professores analisaram um material sobre grandezas e medidas para turmas de 6° ano. As entrevistas foram processadas no Interface de R pour les Analyses Multidimensionnelles de Textes et de Questionnaires, gerando gráficos de similitude que contribuíram com a análise. À luz do modelo Conhecimento da Matemática Incorporada ao Currículo constatamos que os professores pouco identificaram conceitos e propriedades que justifiquem procedimentos a serem utilizados pelos estudantes nas resoluções dos problemas, baseando seu ensino em técnicas, em detrimento de explicações que explorem estruturas matemáticas.
Breve ensaio sobre a cidadania em tempos de pandemia: cidadão neurótico ou inconformado?
Authors: Ribeiro Norberto
Published: September 2023

RESUMO O presente ensaio explora o conceito de neurotic citizen para analisar o tipo de cidadania que parece estar a ser promovido na gestão da pandemia provocada pela covid-19. Da reflexão realizada, emerge a proposta de uma “cidadania inconformada” como alternativa viável a uma “cidadania neurótica”, por esta pressupor o empobrecimento da qualidade democrática das sociedades. Releva-se o papel crucial da educação na promoção de uma cidadania crítica e inconformada, que permita aos indivíduos terem consciência das suas neuroses e de agirem em conformidade com os valores democráticos.
O jogo teatral e a construção do conhecimento simbólico: do jogar à experiência significativa
Authors: Tagliari Mariana , Camargo Robson Corrêa de
Published: September 2023

Resumo Este artigo tem por objetivo analisar a prática do jogo teatral de Viola Spolin (1906-1994) em sua construção do simbólico e como propulsor da experiência significativa (Dewey 1859-1952). A definição de simbólico será pautada nos escritos do filósofo Ernst Cassirer (1874-1945) e da filósofa e educadora Susana Langer (1895-1985). Nesses pensadores, o simbólico se apresenta como elemento fundamental de conhecimento e estruturação da cultura humana, no mito, na religião, na linguagem, na história e na arte. O problema central desta pesquisa baseia-se em estudos teatro-educativos vivenciados pelos autores, tomando-se as práticas do jogo teatral como forma de ampliação do conhecimento para uma integralização do ser, como ser cultural, social, simbólico, na construção das práticas de atos significativos no mundo. Para tanto, a metodologia utilizada é a revisão bibliográfica dos conceitos fundantes dos jogos teatrais em correlação com a construção do conhecimento simbólico. Visamos compreender a arte na produção do contexto simbólico para então fundamentarmos a corporificação como símbolo. Tais estudos objetivam a promoção da experiência consumatória dos praticantes do jogo no contexto teatro-educativo, respaldados no princípio de que a experiência estética jogada possibilitará a ampliação da vivência do jogador, de modo que ele possa ressignificar o seu mundo, construindo-se autonomia e conhecimento da/na experiência estética em constante processo de vivência e aprendizagem, forjado nas teias da cultura.
