Authors: Н.И. Дикарев , Б.М. Шабанов , А.С. Шмелёв
Published: November 2024

Принцип работы процессора с архитектурой управления потоком данных (потокового процессора) позволяет достичь значительно более высокой производительности за счет децентрализованной схемы управления и поиска готовых к выполнению команд в окне из десятков тысяч команд, а не из 200 ко-манд, как в лучших современных процессорах. Однако известные проекты разработки потокового процессора не смогли составить конкуренцию процессорам традиционной архитектуры из-за сложности работы с масси-вами данных и необходимости вести ассоциативный поиск в памяти большой ёмкости. Показано, что в разра-батываемом векторном потоковом процессоре за счет использования оригинального метода хранения масси-вов можно значительно уменьшить требуемую ёмкость ассоциативной памяти и достичь более высокой про-изводительности одного процессорного ядра. Приводятся результаты моделирования программы перемноже-ния матриц на одном процессоре и её ускорение в системе из нескольких ядер разрабатываемого процессора с общей памятью.

Dataflow processor can offer significantly higher performance in comparison with conventional processor due to decentralized control and searching for ready instructions in a much wider window. However, the well-known projects of dataflow processor failed to compete with von-Neumann processor because of array process-ing complexity and the need to perform associative searсh in large capacity memory. In this paper we show that the developing Vector Dataflow Processor (VDP) is able to significantly reduce capacity requirements of associative memory due to original method of storing arrays and to achieve higher performance of a single processor core. The results of matrix multiplication program simulation on a single core VDP and its acceleration on a shared memory multicore VDP are presented.

Published: November 2024

Существует класс задач, работающих в жестком реальном времени, для которых оперативная память является лимитированным ресурсом. Разработка методов со-кращения объёма памяти, используемой ОСРВ, предполагает наличие отладочного стенда и инструментальных средств количественной оценки объема памяти, требуемой для вы-полнения полученного образа. Всю память, требуемую выполняемому образу, можно ус-ловно разбить на статическую и динамическую. Под статической памятью понимается па-мять, требуемая программному коду и сегментам данных образа. Для оценки объема тре-буемой статической памяти предлагается использовать специально разработанную утили-ту, которая выполняется на инструментальной ЭВМ, и позволяет оценить сколько стати-ческой памяти требуется всего, и сколько памяти требуется отдельным частям образа. К динамической памяти относится память, которая выделяется программе уже при ее вы-полнении. Для оценки требуемого объема динамической памяти разработана соответст-вующая функция и указаны точки ее применения. Описан отладочный стенд, созданный специально для разработки компактной операционной системы

There is a class of hard real-time tasks for which RAM is a limited resource. The development of methods for reducing the amount of memory required for the RTOS implies the presence of a testing stand and tools for evaluating the amount of memory required to run the re-sulting image. All the memory required by the executable image can be divided into static and dynamic. Static memory is the memory required for the program code and image data sections. To estimate the amount of static memory required, it is proposed to use a specially designed utili-ty that runs on an instrumental computer and allows to estimate how much static memory is re-quired and how much memory is required for every part of the image. Dynamic memory refers to the memory that is allocated to the program at runtime. To estimate the required amount of dy-namic memory, an appropriate function has been developed and points of its application are indi-cated. A testing stand designed specially for the development of a compact operating system is described

Authors: В. Г. Редько
Published: November 2024

В статье анализируются процессы эволюции в популяциях конкурирующих автономных агентов. Проанализированы три типа моделей. В первой компьютерной модели эволюции рассматривается популяция агентов, которые могут вести борьбу между собой. Причем в процессе мутаций могут исчезать и появляться отдельные сенсоры и эффекторы в нейросетевой системе управления агентов. Показано, что в этой модели «гены агрессивности», ответственные за борьбу между агентами, могут вымирать в процессе эволюционной самоорганизации. Во второй модели рассматривалась эволюция популяций агентов, которые могли как кооперироваться, так и вести борьбу между собой. Проанализированы формы кооперации между агентами в этой модели. В третьей модели рассматривается экономическое сообщество агентов (производителей и инвесторов), которые могут открыто обмениваться информацией между собой. Такой открытый обмен информацией приводит к эффективному сотрудничеству в сообществе агентов

The article analyzes the evolutionary processes in populations of competing autonomous agents. Three types of models have been analyzed. The first computer model of evolution considers a population of agents that can fight among themselves. In this model, the individual sensors and effectors could disappear and appear during mutations. It is shown that in this model the “genes of aggressiveness” responsible for the struggle between agents can die out in the process of evolutionary self-organization. In the second model, the evolution of populations of agents that could cooperate and fight with each other was considered. The forms of cooperation between agents have been analyzed in this model. The third model considers the economic community of agents (producers and investors), which can exchange information between themselves. It is shown that open exchange of information between agents can lead to effective cooperation in the community of agents

This paper deals with the challenge to create virtual models of quadcopter and its remote controller for virtual environment systems. For this, a technology to develop a 3D model of aerial vehicle in 3ds Max system using the constructor comprised of the set of basic elements is proposed. By means of the approach proposed, the geometric model of the quadcopter is com-plemented by new objects, such as rotors and sensors, for which own parameters can be set. In turn, to create a virtual remote controller the developed editor is utilized, where every control (button, joystick, toggle switch, and etc.) is corresponded with its own virtual element with the ability to specify its visual representation and a set of parameters. Using the test control schemes, quadcopter and remote controller models created were approbated in virtual environment com-plex, developed in SRISA RAS

Authors: В.Г. Редько
Published: November 2024

В статье построена модель формирования чувства причинности. Рассмотрена модель двух типов автономных агентов: 1) с чувством причинности и 2) без такого чувства. Агенты с чувством причинности запоминают связи между текущими ситуациями, своими действиями и результатами действий. На основе запомненной информации эти агенты строят базы знаний, характеризующие такие связи, а затем используют эти базы знаний при выборе действий в своем поведении. Агенты без чувства причинности выбирают действия случайным образом. Модель проанализирована путем компьютерного моделирования при целенаправленном поведении агентов. Показано, что агенты с чувством причинности находят цель значительно быстрее, чем агенты без чувства причинности.

Unveiling CO2 reactivity with data-driven methods
Authors: Eckhoff Maike , Bublitz Kerstin L. , Proppe Jonny
Published: November 2024

Carbon dioxide is a versatile C1 building block in organic synthesis. Understanding its reactivity is crucial for predicting reaction outcomes and identifying suitable substrates for the creation of value-added chemicals and drugs. A recent study [Li et al., J. Am. Chem. Soc., 2020, 142, 8383] estimated the reactivity of CO2 in the form of Mayr's electrophilicity parameter E on the basis of a single carboxylation reaction. The disagreement between experiment (E = –16.3) and computation (E = –11.4) corresponds to a deviation of up to ten orders of magnitude in bimolecular rate constants of carboxylation reactions. Here, we introduce a data-driven approach incorporating supervised learning, quantum chemistry, and uncertainty quantification to resolve this discrepancy. The dataset used for reducing the uncertainty in E(CO2) represents 15 carboxylation reactions in DMSO. However, experimental data is only available for one of these reactions. To ensure reliable predictions, we selected a training set composed of this and 19 additional reactions comprising heteroallenes other than CO2 for which experimental data is available. With the new data-driven protocol, we can narrow down the electrophilicity of carbon dioxide to E = –14.6(5) with 95 % confidence.
Accurate Ring Strain Energy Predictions with Machine Learning and Application in Strain-Promoted Reactions
Authors: Liu Zhen , Vinskus Jessica , Fu Yue , Liu Peng , Noonan Kevin , Isayev Olexandr
Published: November 2024

Ring strain energy (RSE) is crucial for understanding molecular reactivity. However, quantitatively determining RSE through experiments or quantum mechanics is resource-intensive, limiting its application on a large scale. We developed a physics-based workflow and a data-driven graph neural network (GNN) capable of reliably predicting RSE in minutes or milliseconds, respectively. For each molecule, the workflow first identifies low-energy conformers, then computes the RSE using the AIMNet2 machine learning interatomic potentials. We validated the approach both computationally and experimentally. Compared to the ωB97M-D4/Def2-TZVPP method, the workflow achieved an R² value of 0.997 and a mean absolute error (MAE) of 0.896 kcal/mol. Using this workflow, we distinguished reactive from non-reactive molecules in copper-free click chemistry and ring-opening metathesis polymerization, demonstrating the workflow's generalizability to diverse molecules. Furthermore, we compiled "RSE Atlas," a computational database of 16,905 single-ring molecules, providing a rich resource for examining factors influencing RSE. Employing this dataset, we trained a GNN that predicts RSE in milliseconds using only 2D molecular information. Our methods render RSE a readily computable property for on-the-fly applications in experimental and computational work.
Pseudo-Lithium Vacancies in Hydrogen Rich Li3OCl
Authors: Williamson Benjamin , Eggestad Kristoffer , Selbach Sverre
Published: November 2024

The antiperovskite Li3OCl is a Li-ion solid electrolyte that has shown a wide variety of properties over a large range of temperatures. Previous reports align Li3OCl as a superionic conductor, however reproducibility has been poor due to its hygroscopic nature suggesting that reports are in fact, Li3 – xOHxCl. Most studies in the literature focus on pure Li3OCl however, and do not take into account the role of hydrogen in the material. Here, we develop a full defect model of H-doped Li3OCl, showing that the nominal Schottky disorder diminishes with hydrogen incorporation. Additionally, H helps to facilitate Li-ion mobility in Li3OCl by ﬁrstly introducing rotatable OH species as well as forming HLi which relaxes oﬀ site to form what we deﬁne as a “pseudo-VLi” enhancing the ionic conductivity in line with experimentally observed values. Intentional hydrogen doping of hygroscopic materials constitute an underexplored strategy for enhancing ionic transport properties.
Glutathione in the noncanonical biosynthesis of teredinibactins
Authors: Sung Youjung , Miller Bailey , Schmidt Eric
Published: November 2024

Teredinibactins are ß-resorcyclic thiazoline dipeptides synthesized by Teredinibacter turnerae T7901, a bacterial symbiont of shipworms in the sea. Through feeding studies, we show that the thiazoline moiety is made from glutathione and its me-tabolites in a noncanonical peptide azoline pathway. Mimicking the biosynthetic reaction, we synthesized both natural and unnatural teredinibactins. The results expand the scope of biological and chemical approaches to aromatic azoline conjugates.

Published: November 2024

Spin conversion in molecular excited states is crucial for the development of next-generation optoelectronic devices. However, optimizing molecular structures for rapid spin conversion has relied on time-consuming experimental trial-and-error, which limits the elucidation of the structure-property relationships. Here, we report a Bayesian molecular optimization approach that accelerates virtual screening for rapid triplet-to-singlet reverse intersystem crossing (RISC). One the molecules identified through this virtual screening exhibits a fast RISC rate constant of 1.3 × 108 s–1 and a high external electroluminescence quantum efficiency of 25.7%, which remains as high as 22.8% even at a practical luminance of 5,000 cd m–2 in organic light-emitting diodes. Post-hoc analysis of the trained machine learning model reveals the impact of molecular structural features on spin conversion, paving the way for informed and precise materials development.
Solution and solid-state structures of dibenzylamino calix[4]arene with complexed solvent molecules
Authors: Cardoso Matteo , Beauchemin-Ratté Jacques , Schaper Frank
Published: November 2024

The solution and solid state structures of 1,3-dibenzylamino calix[4]arene were investigated via NMR and X-ray crystallography for MeCN, ethanol, hexane, THF, chloroform and toluene solvents. Analysis of the obtained structures show a symmetric flattening/pinching of the calixarene for solvents with a roughly cylindrical shape (MeCN, ethanol, hexane) and an asymmetrical flattening of the cone for more anisotropic, flat solvents, such as THF or toluene. Due to the deviation from planarity of the N2O2 fragment in the latter case, these solvents might be best suited for the preparation of octahedral or tetrahedral metal complexes, while the former would be more suitable for the preparation of square-planar complexes.

Authors:   Department of Botany, Faculty of Science, University of Zawia, Zawia, Libya, Alboueishi Fathi A , Suaiee Abdalhalim M ,   Department of Statistics, Faculty of Science, University of Zawia, Zawia, Libya
Published: November 2024

The research explores the use of path analysis to predict the effect of brome grass (Bromus rigidus Roth) density on wheat (Triticum aestivum L.) yield loss. It also studies the relationship between weed density and wheat productivity. The research was conducted during the fall 2020 and spring 2021 seasons. Data were collected from experiments conducted under different densities of weeds and wheat. The statistical analysis program SPSS was used to determine the effect of competition on the amount of loss in wheat and brome productivity, using the Cousens equation and to calculate the competition coefficient between species using the Steward equation. Then, path analysis was used to predict the effect of internal and external variables on plant traits, biomass, and productivity. The results showed that increasing grass density led to a decrease in wheat productivity. The study emphasizes the importance of taking physiological factors into account in crop productivity. Recommendations include implementing measures to control weed density, adjusting wheat planting density to compete effectively with weeds, using weed-resistant wheat varieties, adopting comprehensive farm management practices, and conducting further research to enhance understanding of the interaction between wheat and weeds.

Authors: Nazarchuk Oleksandr
Published: November 2024

The article analyzes the mechanisms of interaction between political elites and state institutions in the process of forming and implementing sustainable development policy in Ukraine. The role of civil society and business in supporting sustainable development is explored, as well as the importance of involving broad segments of the population in decision-making. The transition to sustainable development is a process of changing the value orientations of many people. It was found that close cooperation between representatives of the political elite, state institutions, the public sector and business is necessary to achieve the strategic goals of sustainable development. The priority areas of Ukraine’s sustainable development are environmental safety, energy efficiency, infrastructure development and ensuring social justice. Public administration plays an important role in the implementation of the main principles of sustainable development. Political elites, in turn, are the ones who determine the general strategic vision and make decisions on the implementation of reforms aimed at creating a socio-economic system that meets the principles of sustainable development. The main mechanisms of interaction between the political elite and state institutions in the context of the sustainable development of Ukraine are the development and implementation of the National Strategy for Sustainable Development until 2030, the creation of a system for monitoring and assessing the state of the environment, supporting the development of ecologically clean production, conducting an information and educational campaign on sustainable development, decentralization of power. An important aspect of the interaction between political elites and state institutions is the provision of a comprehensive approach to the implementation of reforms aimed at sustainable development. The effectiveness of the interaction between political elites and state institutions depends on many factors, including the presence of broad public support, the availability of necessary resources, and institutional capacity.

Authors: Djouadi Issam , Rahmane Amal , Abdelaoui Okba , Touati Hichem
Published: November 2024

Objective: This study aims to measure the impact of environmental standards and requirements on trade liberalization in the OECD countries from 1990 to 2021.
 
Theoretical Framework: The study utilizes economic and environmental theories to examine the relationship between regulatory policies and trade liberalization, utilizing key frameworks such as environmental economics, the Kuznets curve, and global trade models to analyze this interaction.
 
Method: We used unconditional quantile regression methods to examine the relationship between environmental regulations and trade liberalization. The model includes variables such as environmental policy stringency, environmental taxes, carbon emissions, and renewable energy production.
 
Results and Discussion: The study concluded that stringent environmental policies increased freedom of trade at different levels of trade liberalization. The results also confirm that environmental tax policies are particularly effective in promoting trade liberalization in countries with weak or low levels of trade liberalization. The results further suggest that in the case of countries where trade liberalization is weak or below average, carbon emissions are associated with increased trade liberalization. Furthermore, renewable energies contribute to deepening levels of trade liberalization in countries characterized by higher-than-average levels of trade liberalization.
 
Research Implications: This study provides insights into how environmental policies can be strategically used to promote trade liberalization. The findings may influence policy-making in areas such as environmental taxation, energy transition, and international trade.
 
Originality/Value: This study explores the impact of environmental regulations on trade liberalization, highlighting how different policies can either promote or hinder trade freedom, especially in economies at different stages of liberalization.

Published: November 2024

Living organisms produce reactive oxygen species (ROS) during the oxygen processing. ROS damage biomolecules and causes oxidative stress. Antioxidants prevent cellular damage against these harmful effects of ROS by neutralizing free radicals. Medicinal plants provide a rich source of antioxidants to reduce oxidative stress and play an important role in the treatment of diseases. Bioactive compounds, especially polyphenols and flavonoids, protect cells against oxidative damage by neutralizing free radicals. Bryophytes, especially mosses, are one of the plant groups that attract attention in this area. Mosses show biologically active properties with secondary metabolites such as terpenes and flavonoids they contain. In this study, extraction of Homalothecium philippeanum moss with ethanol, methanol, and n-hexane solvents was carried out and the biochemical content analysis of the extracts was investigated. 1,2-Benzenedicarboxylic acid, bis(2-methylpropyl) ester was detected as the major component in the ethanol and methanol extracts of the H. philippeanum. Biologically active alkanes such as Tetradecane and Hexadecane were found in the n-hexane extract. The antioxidant activity of moss ethanol extract was investigated using the DPPH method and the EC50 value was determined as 7.084 mg/ml.
Acceptance Factors of Generative AI in EFL Teaching: A Pedagogical Perspective
Authors: Alasmari Talal
Published: November 2024

The emergence of generative artificial intelligence (GenAI) has brought abundant potentials and challenges to the educational sector. This study explores the acceptance and adoption of GenAI in English language and its pedagogical affordability for EFL instructors in tertiary level institutions in the Kingdom of Saudi Arabia. An exploratory sequential mixed method was utilized in this study to gain in-depth insights into the quantitative findings. The first quantitative phase recruited 256 EFL instructors in Saudi Arabia while the follow-up qualitative phase incorporated 17 interviewees. The findings of this study indicate that anthropomorphism, trust, ethics and regulations, and pedagogical affordability are significant determinants of instructors’ acceptance  of GenAI. Conversely, instructors’ acceptance was not significantly influenced by communication capability of GenAI. Yet, there was no evidence of significant differences in GenAI acceptance or adoption due to demographic variables such as gender, age, and degree. The pedagogical affordances of GenAI appears to be the most acceptance factor specifically the productivity and efficiency that GenAI afford for instructors. The study recommends establishing ethical guidelines and embracing transparency and accountability to maintain academic integrity.
From Panthers to Political Dalits: Revisiting the Legacy of Dalit Panthers in India
Authors: Wankhede Harish S.
Published: November 2024

The Panthers had created a rupture from the earlier pattern that Ambedkar has strategized to integrate the Dalits as one of the important political subjects of the modern nation state. The Panthers deviated and invested in two radical ideological traits; the Civil Right Movement in the US (including the Black Panthers’ Party) and radical Marxism (Indian Naxalite movement) to transform Ambedkar’s social theory into an aggressive brand of transformative politics. The Panthers showed open discomfort with the given liberal model of democratic politics and attempted to shift the traditional Dalit political ideology into a revolutionary force. Though the Panthers’ innovations have impressed the urban Dalit youths and intelligentsia, it failed miserably in forming a concrete political alternative at the regional or the national level. I have concluded that, with the rise of Bahujan Samaj Party (BSP), the Dalits were introduced to an improvised liberal political agenda, different from the earlier variants of Ambedkar’s participatory politics and the Panthers’ militant rhetoric. It shows that the Dalits are more convinced and engaged with the liberal-democratic model and consciously refute the militant and radical methods for political actions.

This study compares various categorization methods to assign land use and land cover (LULC) classes. Using Geographic Information Systems (GIS) and Remote Sensing (RS) to leverage the dynamic and complex area of LULC, this study examines the potential of different machine learning classification methods. Precise differentiation and classification of various land cover categories, such as green vegetation, urban areas, water bodies, dark green vegetation, and bare terrain, are made possible by the great spatial and spectral resolution of Landsat imagery. For efficient land management and planning, the integration of Landsat data with GIS and RS approaches provides insightful information about the distribution and temporal changes in LULC. This study uses four classifiers to explore the principles of supervised machine learning techniques and identify their drawbacks and advantages. Testing results show that the Support Vector Machine with four kernel linear-99.17%, radial basis (RBF)-99.11%, Sigmoid-99.11% and Polynomial-99.11% is a reliable option for LULC classification, outperforming than other classifiers in terms of accuracy, including the Minimum Distance Classifier (MD-93.47%), Maximum Likelihood Classifier (MLC- 98.98%), and Mahalanobis Distance Classifier (MH-97.83%). Among the tested classifiers, SVM with four kernels notably shows the highest accuracy. With their essential insights for well-informed decision-making towards sustainable development and resource utilization, our findings add to a thorough understanding of LULC dynamics. For accurate mapping and long-term monitoring of deviations in land cover (LC), the study emphasizes the value of using front-line classification systems in remote sensing applications
MONTE CARLO METHOD FOR CALCULATING LIGHT FIELDS CHARACTERISTICS IN SEAWATER
Authors: Glukhovets D. I.
Published: November 2024

The development of numerical methods for solving the integro-differential radiation transfer equation remains a relevant task. Among them, we can highlight the Monte Carlo method, which is in demand in various niches of modern ocean optics. The purpose of this work is a clear and concise presentation of the basics of the forward Monte Carlo method of light fields modeling in seawater, accompanied by a detailed description of its software implementation. The basics of the method are described, the procedures for choosing the type of interaction, the mean free path and the direction of photon motion are described. A simple case is considered, corresponding to an infinitely distant point source of unpolarized light, the absence of atmospheric influence, a smooth air-seawater interface, and the absence of stratification of inherent optical properties. In this case, realistic values of the absorption and scattering coefficients were used, calculated in accordance with the Case 1 model for a chlorophyll concentration of 1 μg/L, and a strongly elongated Henyey-Greenstein phase function with the parameter g = 0.95. The Fresnel reflection of light from the air-seawater interface was taken into account. The relative errors in the values of the diffuse attenuation coefficient for downward irradiance K d and the diffuse reflectance R, calculated in the spectral range of 400–700 nm using 106 photons, in comparison with the HydroLight results were 1.5 % and 0.4 %, respectively. Spectral calculation on one core of a 2017 Intel Core i5-8250U mobile processor in MATLAB takes 6 minutes. An assessment of the choice of the optimal number of photons required to obtain the desired quantities with a given accuracy was made. The implemented method is useful for becoming familiar with the basic principles used to numerically solve the radiative transfer equation in seawater using statistical methods and is used in the “Ocean Optics” course, taught by the author to 4th year students of the Department of Thermohydromechanics of the Ocean at MIPT.
THE EFFECT OF THE TIDE ON WATER EXCHANGE THROUGH THE LA PEROUSE STRAIT
Authors: Shevchenko G. V. , Maryzhikhin V. E.
Published: November 2024

Based on the analysis of oceanographic survey materials on the standard section S1 and satellite information, important features of the influence of tidal currents on the formation of hydrological conditions in the La Perouse Strait and adjacent waters have been identified. It was revealed that in the warm season, when the seasonal flow is directed from the Sea of Japan to the Sea of Okhotsk (Soya Warm Current), at the high tide in the northern part of S1 section the cold water with low salinity is observed in the surface layer (the temperature may differ from the southern stations by 3 times, and the salinity by 2 psu). At low tide in the northern part of S1 the water is also cold, but with high salinity, which indicates the inflow of water from the West Sakhalin current into the Sea of Okhotsk. The temperature contrasts between the northern and southern parts of the Strait are also confirmed by satellite observations. During the cold season in the northern part of the strait, there is a flow of colder and less salty Okhotsk Sea water into the southeastern part of the Tatar Strait. It is wider and more developed in depth compared to the summer season. At low tide, when the tidal current is directed to the east, this flow narrows noticeably.
Participación política, estereotipos y redes de apoyo entre personas mayores migrantes
Authors: Manjarrés Ramos Elízabeth
Published: November 2024

Aunque hay avances respecto al estudio de la participación política en la vejez, falta conocimiento sobre la participación de personas migrantes mayores en protestas. El propósito del presente estudio etnográfico fue el de conocer el papel de adultos mayores migrantes en las protestas por el pago de pensiones organizadas por venezolanos en España, desde la perspectiva subjetiva de los propios actores. Se realizaron entrevistas a 22 manifestantes, complementadas con revisión documental y observación participante. Los hallazgos refutan la idea de disminución de la participación política en la vejez, cuestionando estereotipos como la pasividad y vulnerabilidad. Además, las protestas se presentan como formas de agencia y resistencia identitaria transnacional que desafían e instrumentalizan estigmas relacionados con la vejez. En conclusión, este estudio contribuye a comprender la participación política de los mayores migrantes, subrayando su papel significativo en la acción colectiva y cuestionando estereotipos edadistas.

Le corps de Keetje, malmené dans la fiction et dans sa traduction ?
Authors: Fortunati Marie
Published: November 2024

L’écrivaine belge Neel Doff (1858-1942) a rédigé toute son œuvre en français alors que ce n’était pas sa langue maternelle. Sa trilogie autobiographique met le « féminin » et le « corps » au cœur de la thématique à travers l’obscène, le traumatisme pubertaire et la prostitution.
Le corps est un « texte signifiant à déchiffrer 1  » et nous tâcherons d’en découvrir davantage en comparant l’œuvre de Doff avec ses traductions en langue néerlandaise et allemande. L’un des objectifs est de déterminer dans quelle mesure les « erreurs » de traduction, ayant trait au corps, ouvrent d’autres fenêtres d’interprétation.
Afin de mieux comprendre l’origine de ces « déviations », les extraits seront d’abord analysés selon les théories de dépaysement et domestication (Venuti, 2007) et de retraduction (Berman, 1990). Nous émettons l’hypothèse selon laquelle la vie (Delisle, 2002) et le genre (Von Flotow, 1991) de la personne qui traduit influencent les choix traductifs. Autre hypothèse, les stratégies de traduction féministe, objet de nombreuses polémiques, n’éviteraient-elles pas l’effacement que subit le corps de Keetje ?
