A Promessa de Papert: Tecnologias Digitais, Inovação e Práticas Educativas
Authors: Soffner Renato 
Published: December 2021

Este trabalho tem por objetivo analisar o emprego das tecnologias digitais nos processos educativos a partir da proposta de Seymour Papert, pioneiro no uso de computadores na educação, que buscava a inovação em práticas educativas. Pelo método da pesquisa bibliográfica a partir de fontes primárias e secundárias relativas ao trabalho de Papert, busca-se verificar se sua proposta original foi, de fato, implementada, ou se houve uma distorção de entendimento e de prática. Justifica-se o trabalho pelo interesse que o tema da tecnologia aplicada aos processos educacionais apresenta, após décadas de teoria e prática. Os resultados da pesquisa permitem concluir que a promessa de Papert, para o emprego das tecnologias digitais em práticas educativas, se perdeu - muitas vezes, na confusão entre meios e fins, e na falta de clareza sobre o real papel epistemológico das tecnologias digitais, embora seja sua proposta dotada de fundamentos sólidos para que a inovação educativa seja realizada.

EJA e a negação ao direito dos bens culturais em territórios pobres
Authors: Costa Adriana Alves Fernandes , Alcoforado Luís , Nivia Maria Vieira Costa  
Published: December 2021

O artigo objetivou problematizar a escassez e o não acesso aos bens culturais vivenciados pela população da Educação de Jovens e Adultos (EJA) que vive em um dos munícipios que compõem a região metropolitana do estado do Rio de Janeiro. A pesquisa abordada, predominantemente qualitativa, produziu dados através dos seguintes instrumentos: entrevista e questionário, ambos semiestruturados. Os participantes constituíram uma amostra de 66 estudantes que compreendia o alunado das sete escolas do segmento do Ensino Fundamental II, da referida modalidade. O fenômeno de retração das matrículas foi identificado pelo estudo como a negação e/ou restrição de alcance ao bem cultural, denominado escola. Os demais espaços, a saber: museus, teatros, cinemas e bibliotecas públicas, também foram retratados como bens culturais, aos quais o referido público é privado ao direito, em especial nos territórios pobres ou vulneráveis. Os dados, analisados via software MAXQDA e à luz do Paradigma Indiciário de Análise, evidenciaram a escola como constitutiva de acesso a culturas, não unicamente aquelas que se fazem em seu interior, mas no caso da população jovem, adulta e idosa é, principalmente, por meio dela que acontece o acesso aos outros espaços. Os resultados desenvolvidos indicaram que a redução de matrículas na modalidade denota impactos de negação de direitos aos bens culturais.

Rurification of Religion. Foci and Suggrundaria at the Roman Vicus of Falacrinae (Cittareale, Rieti, Italy)
Authors: Gasparini Valentino 
Published: December 2021

The results of the archaeological exploration of the Roman vicus of Falacrinae, placed in the Upper Sabina 78 miles north-east of Rome, represent excellent first-hand material for testing the concept of “rurification” of religion. The frequentation of the area goes back over time at least to the late Neolithic, but it is only in the Archaic period that a temple was built, soon converting itself into a sort of pole of attraction of the local community. After the Roman conquest (290 BCE), an entire village gradually arose around the monument. 129 sacrificial foci, dated between the late 3rd and the second half of the 1st cent. BCE (probably linked with the festivals of the Feriae Sementivae, Paganalia or Compitalia), and few burials (suggrundaria) belonging to perinatal foetuses of 30/40 weeks of gestation, dated during the 2nd and the first half of the 1st cent. BCE, are the most intriguing ritual practices that the excavations have been able to identify. The analysis of these practices encourages to conclude that the local rural communities: 1) adopted group-styles of religious grouping significantly different from those taking place in urban contexts; 2) could strongly modify hierarchies and rituals performed in the cities; 3) cannot necessarily be considered as “deviant” from the normative point of view; 4) could easily negotiate between local religious traditions and urban patterns.
Desigualdades y discriminaciones de las trabajadoras sexuales migrantes
Authors: González Fernández Tamara 
Published: December 2021

Ser migrante en situación administrativa irregular implica no ser considerada/o ciudadana/o, no tener derecho a tener derechos. Si además estás ocupado en alguna forma de economía informal mediante una actividad no reconocida tampoco puedes acceder a la ciudadanía a través del trabajo. Esta es la realidad las trabajadoras sexuales migrantes en España quienes sufren múltiples discriminaciones derivadas de la intersección entre las políticas de intervención abolicionistas y la política migratoria europea. Desde la epistemología feminista y la perspectiva de los derechos humanos, se recogen en este trabajo una aproximación al estatuto jurídico de estas mujeres desde sus experiencias y sus reclamaciones.

Відносини між Туреччиною і СРСР в епоху правління президента Тургут Озала
Authors: Курбан В. , Джафаров Н. , Асланлі А. 
Published: December 2021

Відносини між Туреччиною і СРСР в епоху правління президента Тургута Озала є останнім етапом взаємодії між двома країнами (1923–1991 рр.). У її розвитку в 1983–1991 рр. особливе місце посідає історичне тло, створене російсько-турецькими відносинами, які почали формуватися з XV ст., і турецько-радянськими відносинами в ХХ ст. У період правління Т. Озала (1983–1991 рр.) міжнародною обстановкою, в якій взаємодіяли Туреччина й СРСР, була система холодної війни (1945–1991 рр.), головною особливістю котрої була конфронтація між Західним і Східним блоками в ідеологічних, політичних, військових та економічних напрямах.
Відносини між Туреччиною і СРСР загалом також значною мірою визначалися багатоплановою боротьбою між Західним і Східним блоками та їхнім курсом. Коли конфлікт пом’якшав, це поліпшило відносини між Туреччиною та СРСР, але коли він загострився, це негативно вплинуло на відносини між цими країнами. Справді, ситуація позначилася на курсі відносин між Туреччиною і СРСР у період президентства Т. Озала. Пом’якшення і навіть співпраця набрали обертів, коли Генеральним секретарем Комуністичної партії СРСР став Михайло Горбачов. Спроби М. Горбачова реформувати радянську систему у відносно ліберальному напрямку та його зовнішньополітичні підходи започаткували трансформацію відносин із Західним блоком від конкуренції до співпраці.
Міжнародна система в період головування Т. Озала, динаміка взаємин, внутрішня динаміка обох країн та їхній вплив на зовнішню політику зумовили необхідність розвитку багатопланових відносин і забезпечення співпраці між Туреччиною і СРСР.
У цій статті дається оцінка відносин між Туреччиною і СРСР у період правління Т. Озала через теоретичні та практичні виміри, засновані на підході ліберальної теорії в міжнародних відносинах.

ASSESSMENT OF THE IMPACT OF TECHNOLOGICAL HEREDITY ON INDICATORS OF RELIABILITY, DURABILITY AND ENVIRONMENTAL SAFETY OF ELEMENTS OF GAS TRANSMISSION SYSTEMS
Authors: Kotukh Volodymyr , Kaptsova Natalia , Donskoy Dmitry , Paleyeva Kateryna 
Published: December 2021

Modern gas transmission systems are power facilities based on a main pipeline, which is a continuous pipe, along which devices are placed that provide gas pumping at predetermined parameters. Unlike other linear structures, such as roads, railways, the main pipeline throughout the entire period of operation is in a complex stress state under the influence of the internal pressure of the pumped product and functions as a pressure vessel. The operational reliability, durability and environmental safety of gas transmission systems are ensured by various control devices and pipe fittings.
The article discusses issues related to predicting the operation of pipe fittings during the operation of the gas transmission system, while ensuring the required reliability, durability and environmental safety. An analysis of the phenomena of technical heredity is given, with the help of which it is possible to determine the causes of deviations in the output parameters of pipe fittings in the process of their manufacture or repair. It has been proved that the main feature of technological heredity is the transfer of a certain technological property from the previous technological operation to subsequent ones, characterized by the transfer coefficient of technological heredity. An indispensable condition for the monotonicity of changes in the transmission coefficient of technological heredity in order to ensure the required quality of manufacture or repair of pipe fittings is revealed. The economic principle of predicting the quality of manufacturing or repair of products is proposed for use, a relationship is found between the initial and output technological properties of pipe fittings, a route is chosen to achieve the required quality of its manufacture or repair, including procurement and finishing technological operations.

The correlation method for measuring of the coolant fl rate is used in the operation of nuclear power plants and is widespread in research practice including study of turbulent fl hydrodynamics. However the question of its applicability and possibilities in studies using the matrix conductometry method remains open. Earlier the algorithm for determining of the correlation fl rate using a conductometric measuring system was highlighted and the error of the results obtained was estimated and the dependence of the influence of noise and the time of data collection on the reliability of results was investigated. These works were carried out using two independent mesh sensors and the issue of the resolution of local velocity components was not covered. The purpose of this work was to test the correlation method for measuring velocity with temporal and spatial sampling using two-layer mesh conductometric sensors.As the result velocity cartograms were obtained over the cross-section of the experimental model with quasi-stationary mixing and the value of the average flow rate is in good agreement with the values obtained from the standard flow meters of the stand. Also measurements were carried out at a non-stationary setting of the experiment and realizations of the flow rate and velocity components of the flow at the measuring points were obtained.Analysis of the obtained values allows to conclude about the optimal data collection time for correlation measurements, as well as the reliability of results.
Sustainable Recovery: Signs of Recovery?

The 2021 SPE Annual Technical Conference and Exhibition (ATCE) was held in September as a hybrid (in-person and virtual) event in Dubai with more than 6,000 participants, with the health and safety of the participants being our highest priority. While the number of attendees is lower than in previous years, there was a general feeling that we may finally be getting out of the pandemic situation, after 18 months of a complete trans-formation of the way we work, communicate, and move.
Thanks to the Conference Chair Ali Al Jarwan, CEO of Dragon Oil; Program Committee Chair Fareed Abdulla AlHashmi, COO of Dragon Oil; and the ATCE Executive and Program committees for organizing an excellent event under the theme of “The New Oil and Gas Journey: Agility, Innovation, and Value Creation.” The conference included 80 technical sessions, six plenary and panel sessions, and eight special sessions, spanning digitalization, electrification, sustainability, and emerging themes. Our appreciation goes to the sponsors, the exhibitors, the presenters, the volunteers, and the SPE staff.
Dubai and the UAE, 1 week before the 2020 World Expo, were great hosts. Congratulations to the winners of the SPE (and AIME) International, Regional, and Student awards (https://jpt.spe.org/spe-honors-2021-international-award-recipients-during-annual-meeting). Many of them were able to travel to Dubai to receive their recognition. The Startup Village Awards, organized in collaboration with Rice University, was also well attended, and the winners were recognized (https://jpt.spe.org/2021-atce-startup-village-competition-winners-announced). The dynamism of the city of Dubai and the country of UAE and their capacity to project themselves in the future with a unique 50-year strategical timeframe that spans the period 2021–2071 never cease to amaze me.
The world, including developing economies, has expanded significantly the COVID-19 vaccination campaign, reaching more than 6 billion doses administered, and nearly half of the world has received at least one dose of vaccination as of early October. The “green list” of countries deemed safe for travel is expanding after a summer that has seen a major impact of the COVID-19 Delta variant.
Oil and gas demand is recovering for sectors such as transport and industry, even though the airlines may not see pre-pandemic levels of activity before 2025. Massive amounts of public funding injected to fuel the world’s economic recovery have been announced in Europe, the US, and Asia, adding up to trillions of dollars. However, economic recovery from the pandemic will take time, as there is a major backlog in global manufacturing activities impacting consumer markets and creating inflationary pressures.
Technology Focus: Drilling and Completion Fluids (November 2021)
Authors: Kuru Ergun 
Published: December 2021

Design and development of optimal drilling-fluid systems, as well as their proper maintenance while drilling, are essential components of any successful drilling campaign. As the oil and gas industry is drilling in more-challenging areas (e.g., unconventional shale oil/gas wells, deepwater offshore wells, and deep high-pressure/high-temperature sour gas wells), the demand for more-accurate real-time assessment of the downhole state of the drilling fluids during drilling operations increases.
Recent developments in drilling systems automation provide a multitude of opportunities to have real-time monitoring of drilling-fluid properties and early diagnosis of drilling-fluid-related complications that might arise while drilling. Coupled with closed-loop control of surface and downhole drilling-fluid properties, automated monitoring of fluid properties would allow rig personnel to make timely corrections to the drilling-fluid program, which eventually would lead to more-cost-efficient and safer drilling operations.
This feature provides examples of such new technologies that can be used as part of the automated drilling-fluid monitoring system, allowing real-time control of drilling-fluid rheological properties (i.e., density and viscosity) and management of solids content with potential benefits of real-time management of equivalent circulating density, effective hole cleaning/cuttings transport, increasing drilling rate, and reducing nonproductive time, resulting in safer wells drilled at minimum costs.
