Authors: Fang Hanzhen , Ren Yi , Yang Shi , Tan Qiuting , Gao Tao , Bao Anhong , Hu Man
Published: December 2023

The problems of large deformations, failures, and fractures that agricultural tillage tools may encounter during the cultivation process has long been a concern in the field of agricultural machinery design and manufacturing. It is important to establish a more accurate numerical model to effectively predict tools’ plastic deformation failures and ductile fracture failures. This research develops a numerical model for predicting the plastic deformation failure and ductile fracture failure of agricultural tillage tools using the smoothed particle hydrodynamics (SPH) method and the Johnson–Cook constitutive model. The model uses the Drucker–Prager criterion to describe the elastic–plastic constitutive behavior of the soil, the von Mises criterion to describe the Johnson–Cook constitutive model of the tool, and the coupling condition with the Lennard-Jones repulsive force to describe the interaction between the tool and soil. The numerical results show that the proposed model can effectively simulate the interaction between the tool and soil, as well as the tool’s plastic deformation failure and ductile fracture failure during the agricultural cultivation process. It can also predict the variation trend of the cutting force of the tool. This helps to provide a new approach for the numerical simulation of such problems.
Syncretism Narrative and the Use of Material Objects within Some Neo-Pentecostal Circles in Contemporary South Africa
Authors: Shingange Themba
Published: December 2023

African Pentecostal Christianity presents interconnectedness with African cultures, spiritualities, and religiosity in many ways. Among many other practices that demonstrate this interconnectedness is the use of material objects common within some African Pentecostal Christian spaces, African cultures, spiritualities, and religions. The advent of neo-Pentecostalism in South Africa has brought some controversies in the use of material objects within the broader African Pentecostalism. This has led to the outright demonization and to the conclusion that this practice was fundamentally syncretistic. This article investigated the syncretism narrative given the use of material objects within some neo-Pentecostal spaces in contemporary South Africa. It scrutinized the syncretism narrative and problematized it as the continuation of the missionary-colonial project that demonized African religious and cultural practices. It was argued that this constitutes coloniality that uses a “cultural bomb” that seeks to eradicate African customs, cultures, religions, and practices including the use of material objects. The study was conducted through the desktop research methodology focusing on secondary literature on African Pentecostalism, African neo-Pentecostalism, and syncretism. The findings indicated that the syncretism narrative is often applied to African Pentecostalism and seldom used with other Christian traditions, especially those of Western descent. Again, when the term is used, non-syncretistic elements are often not acknowledged. Thus, the need to transform the current narrative was highlighted.
Identifying Old-Growth Forests in Complex Landscapes: A New LiDAR-Based Estimation Framework and Conservation Implications

Published: December 2023

Old-growth forests provide many ecosystem services and benefits. However, they are becoming increasingly rare and thus are an urgent priority for conservation. Accurately mapping old-growth forests is a critical step in this process. Here, we used LiDAR, an improved individual tree crown delineation algorithm for broadleaved forests, Gaussian mixture modelling, and a rule-based classification key to map the extent and location of old-growth forests across a topographically and ecologically complex landscape of 337,548 ha in southeastern Australia. We found that variation in old growth extent was largely driven by the old growth definition, which is a human construct, rather than by uncertainty in the technical aspect of the work. Current regulations define a stand as old growth if it was recruited prior to 1900 (i.e., >120 years old) and is undisturbed (i.e., <10% regrowth canopy cover and no visible disturbance traces). Only 2.7% (95% confidence intervals ranging from 1.4 to 4.9%) of the forests in the study landscape met these criteria. However, this definition is overly restrictive as it leaves many multi-aged stands with ecologically mature elements (e.g., one or more legacy trees amid regrowth) unprotected. Removing the regrowth filter, an indicator of past disturbances, increased the proportion of old-growth forests from 2.7% to 15% of the landscape. Our analyses also revealed that 60% of giant trees (>250 cm in diameter at breast height) were located within 50 m of cool temperate rainforests and cool temperate mixed forests (i.e., streamlines). We discuss the implication of our findings for the conservation and management of high-conservation-value forests in the region.

Published: December 2023

Chinese calligraphy, revered globally for its therapeutic and mindfulness benefits, encompasses styles such as regular (Kai Shu), running (Xing Shu), official (Li Shu), and cursive (Cao Shu) scripts. Beginners often start with the regular script, advancing to more intricate styles like cursive. Each style, marked by unique historical calligraphy contributions, requires learners to discern distinct nuances. The integration of AI in calligraphy analysis, collection, recognition, and classification is pivotal. This study introduces an innovative convolutional neural network (CNN) architecture, pioneering the application of CNN in the classification of Chinese calligraphy. Focusing on the four principal calligraphy styles from the Tang dynasty (690–907 A.D.), this research spotlights the era when the traditional regular script font (Kai Shu) was refined. A comprehensive dataset of 8282 samples from these calligraphers, representing the zenith of regular style, was compiled for CNN training and testing. The model distinguishes personal styles for classification, showing superior performance over existing networks. Achieving 89.5–96.2% accuracy in calligraphy classification, our approach underscores the significance of CNN in the categorization of both font and artistic styles. This research paves the way for advanced studies in Chinese calligraphy and its cultural implications.

Published: December 2023

To address the challenges of balancing accuracy and speed, as well as the parameters and FLOPs in current insulator defect detection, we propose an enhanced insulator defect detection algorithm, ML-YOLOv5, based on the YOLOv5 network. The backbone module incorporates depthwise separable convolution, and the feature fusion C3 module is replaced with the improved C2f_DG module. Furthermore, we enhance the feature pyramid network (MFPN) and employ knowledge distillation using YOLOv5m as the teacher model. Experimental results demonstrate that this approach achieved a 46.9% reduction in parameter count and a 43.0% reduction in FLOPs, while maintaining an FPS of 63.6. It exhibited good accuracy and detection speed on both the CPLID and IDID datasets, making it suitable for real-time inspection of high-altitude insulator defects.
Fully Convolutional Neural Network for Vehicle Speed and Emergency-Brake Prediction
Authors: Itu Razvan , Danescu Radu
Published: December 2023

Ego-vehicle state prediction represents a complex and challenging problem for self-driving and autonomous vehicles. Sensorial information and on-board cameras are used in perception-based solutions in order to understand the state of the vehicle and the surrounding traffic conditions. Monocular camera-based methods are becoming increasingly popular for driver assistance, with precise predictions of vehicle speed and emergency braking being important for road safety enhancement, especially in the prevention of speed-related accidents. In this research paper, we introduce the implementation of a convolutional neural network (CNN) model tailored for the prediction of vehicle velocity, braking events, and emergency braking, employing sequential image sequences and velocity data as inputs. The CNN model is trained on a dataset featuring sequences of 20 consecutive images and corresponding velocity values, all obtained from a moving vehicle navigating through road-traffic scenarios. The model’s primary objective is to predict the current vehicle speed, braking actions, and the occurrence of an emergency-brake situation using the information encoded in the preceding 20 frames. We subject our proposed model to an evaluation on a dataset using regression and classification metrics, and comparative analysis with existing published work based on recurrent neural networks (RNNs). Through our efforts to improve the prediction accuracy for velocity, braking behavior, and emergency-brake events, we make a substantial contribution to improving road safety and offer valuable insights for the development of perception-based techniques in the field of autonomous vehicles.
Inhibitory Effect of Mistletoe Ointment on DNCB-Induced Atopic Dermatitis in BALB/c Mice
Authors: Hong Chang-Eui , Lyu Su-Yun
Published: December 2023

Atopic dermatitis (AD) is increasingly prevalent globally. However, the frequent and prolonged use of corticosteroids, which are commonly employed for AD treatment, carries potential side effects. Korean mistletoe (Viscum album L. var. coloratum), a perennial parasitic plant, has demonstrated various biological effects. In this study, we conducted in vivo investigations to determine whether Korean mistletoe possesses anti-inflammatory effects that play pivotal roles in regulating the pathological mechanisms of AD. BALB/c mice with AD-like skin lesions induced by 2,4-dinitrochlorobenzene (DNCB) were utilized to explore the therapeutic effects of 1% and 2% Korean mistletoe extract (KME) ointments. The KME ointment was topically applied to the dorsal surface of the BALB/c mice, and they were categorized into four distinct groups: normal, DNCB-induced, DNCB-induced with 1% KME ointment, and DNCB-induced with 2% KME ointment. Each assessment parameter employed to evaluate the curative impact of the KME ointment displayed improvement with the application of the 1% KME ointment. While the effects observed were less pronounced than those of the 1% KME ointment, the overall therapeutic outcomes were also evident with the utilization of the 2% KME ointment. The results suggest the potential of Korean mistletoe as a viable therapeutic agent for AD. Further investigations are warranted to elucidate the underlying mechanisms of action.

Published: December 2023

Background: this observational and cross-sectional study aimed to describe training, pharmacological ergogenic aids, dehydration, and nutrition strategies during a peak week in competitive bodybuilders and monitor changes that occurred across this period. Methods: Ten amateur bodybuilders were followed during a peak week phase and one day post-contest. Training, diet, dehydration protocol, anabolic steroid use, and nonsteroidal agents were recorded, prescribed, and supervised by the same coach in charge. Body composition, resting metabolic rate, and circumferences were assessed by the research team. Results: Overall, during the peak week phase, the use of anabolic steroids, diuretics, and other pharmacological aids was high among athletes, and the dose and frequency were similar between competitors. Despite the use of supraphysiological doses of drugs, bodybuilders displayed a statistical reduction of lean mass markers, resting metabolic rate, and fat mass markers, possibly influenced by the performance of high volumes of aerobic exercise combined with dietary energy restriction. Conclusions: The main findings of this study display that the coach in charge of Brazilian bodybuilders applied the same anabolic steroid, diuretic, and other pharmacological protocols for all competitors. Moreover, the protocols employed by bodybuilders did not fully attenuate the loss of lean mass during the peak week period.

Published: December 2023

In the market-shaping literature, markets are viewed as the results of intentional and planned acts. Market shapers do not often create technology themselves despite the fact that technical advancements can hasten changes in smart sustainable marketing. This study assessed the development of emerging technologies in business informatics with a focus on smart sustainable marketing and its relevant emerging technologies. Data were collected using an online questionnaire from 320 marketing professionals in Greece. The study revealed that emerging technologies have a significant relationship with smart sustainable marketing. Drivers of smart sustainable marketing positively enhance the effectiveness of smart sustainable marketing, and innovations in business informatics have a positive effect on smart sustainable marketing. It is clear from our results that the area of emerging technologies and smart sustainable marketing has not received much attention since such developments depend on complementary technologies that make it possible for emerging methods or technologies to integrate resources and co-create value. This study conceptually distinguishes between technology as a market offering and technology as a business platform for market shaping and innovation. Managers in the business industry and elsewhere are urged by this research to more closely examine the development of ancillary technologies, which could serve as platforms for market innovation and market shaping. Discovering and taking advantage of these opportunities is crucial for success in smart sustainable marketing. This study also presents a significant addition to the academic community because of the empirical evidence on the relationships between business informatics, smart sustainable marketing, and new technology. In terms of technology, it expands the theoretical framework of market dynamics and offers a novel perspective on the ways in which technology influences the structure and sustainability of markets.

The presence of unsaturated soil is critical in geotechnical engineering since the matric suction may aid in accommodating the pile shaft capacity. The design of piles can be optimized by incorporating unsaturated soil mechanics principles. Hence, the amount of waste materials can be reduced, the duration of pile installation can be expedited, and the amount of energy used for casting the pile can be optimized, resulting in more sustainable design and construction of piles. Conventional α, β, and λ methods and modified α, β, and λ methods are the common models that are used for calculating the shaft capacity by incorporating soil–water characteristic curves (SWCCs). However, in our opinion, we feel that the investigation of the influence of seepage infiltration due to rainfall on the shaft capacity of piles, calculated using both analytical means and numerical analysis, has been dealt with inadequately in past studies. The objective of this study is to investigate changes in the shaft pile capacity according to suction changes due to rainwater infiltration for the greater reliability of the pile design, using both analytical and numerical studies with the finite element method (FEM). Sand and kaolin, which are typical components of coarse-grained and fine-grained soil, are used in this study. The laboratory results were incorporated into PLAXIS 3D (Version 22), and a coupled analysis was carried out, utilizing the meteorological conditions in Astana. The results showed that the decreases in matric suction in sand and kaolin are similar after their subjection to rainfall, yet sand produces a higher shaft capacity compared to kaolin. The modified β method offers a higher shaft capacity compared to the other methods due to the effective stress factors being taken into account. The modified α and λ methods are recommended for short piles because they are more sustainable, whilst the modified β method is preferable for long piles. Overall, unsaturated soil conditions should be applied to optimize the foundation design since they generate a higher shaft capacity.
Turning the Tide: An Analysis of Factors Influencing the Adoption of Biodiversity-Enhancing Measures on Agricultural Land at the German Baltic Coast

Published: December 2023

The agricultural sector plays a major role in turning the tide of biodiversity loss. In the European Union, land use decisions and biodiversity are strongly influenced by the Common Agricultural Policy (CAP). Despite massive investment in subsidies to incentivize environmentally friendly farming practices, the CAP has so far failed to preserve the biodiversity of Europe’s farmland. A simplistic understanding of farmers’ motivations, dominated by rational, economic cost–benefit considerations, is one of the reasons for this failure. Our study contributes to this discussion through the identification of factors influencing the decision making of farmers. Through a case study approach in a biodiversity-rich region on the German Baltic coast—the so-called hotspot 29—we classify a number of personal, social/group, and external factors relevant to the implementation of biodiversity-enhancing measures on agricultural land. Applying a model of pro-environmental behavior, we illustrate the interlinkages between factors and outline potential solutions to support biodiversity-enhancing behavior.
Symmetry-Breaking-Induced Internal Mixing Enhancement of Droplet Collision
Authors: Leng Yupeng , He Chengming , Wang Qian , He Zhixia , Simms Nigel , Zhang Peng
Published: December 2023

Binary droplet collision is a basic fluid phenomenon for many spray processes in nature and industry involving lots of discrete droplets. It exists an inherent mirror symmetry between two colliding droplets. For specific cases of the collision between two identical droplets, the head-on collision and the off-center collision, respectively, show the axisymmetric and rotational symmetry characteristics, which is useful for the simplification of droplet collision modeling. However, for more general cases of the collision between two droplets involving the disparities of size ratio, surface tension, viscosity, and self-spin motions, the axisymmetric and rotational symmetry droplet deformation and inner flow tend to be broken, leading to many distinct phenomena that cannot occur for the collision between two identical droplets owing to the mirror symmetry. This review focused on interpreting the asymmetric droplet deformation and the collision-induced internal mixing that was affected by those symmetry breaking factors, such as size ratio effects, Marangoni Effects, non-Newtonian effects, and droplet self-spin motion. It helps to understand the droplet internal mixing for hypergolic propellants in the rocket engineering and microscale droplet reactors in the biological engineering, and the modeling of droplet collision in real combustion spray processes.
Geometric Origin of the Galaxies’ Dark Side
Authors: Modesto Leonardo , Zhou Tian , Li Qiang
Published: December 2023

We show that Einstein’s conformal gravity can explain, simply, and on the geometric ground, galactic rotation curves, without the need to introduce any modification in both the gravitational as well as in the matter sector of the theory. The geometry of each galaxy is described by a metric obtained, making a singular rescaling of Schwarzschild’s spacetime. The new exact solution, asymptotically anti-de Sitter, manifests an unattainable singularity at infinity that cannot be reached in finite proper time; namely, the spacetime is geodetically complete. It deserves to be noticed that, in this paper, we have a different opinion from the usual one. Indeed, instead of making the metric singularity-free, we make it apparently but harmlessly even more singular than Schwarzschild’s. Finally, it is crucial to point out that Weyl’s conformal symmetry is spontaneously broken into the new singular vacuum rather than the asymptotically flat Schwarzschild’s one. The metric is unique according to the null energy condition, the zero acceleration for photons in the Newtonian regime, and the homogeneity of the Universe at large scales. Once the matter is conformally coupled to gravity, the orbital velocity for a probe star in the galaxy turns out to be asymptotically constant consistent with the observations and the Tully–Fisher relation. Therefore, we compare our model with a sample of 175 galaxies and show that our velocity profile very well interpolates the galactic rotation curves after a proper choice of the only free parameter in the metric. The mass-to-luminosity ratios of galaxies turn out to be close to 1, consistent with the absence of dark matter.
EcoHIV-Infected Mice Show No Signs of Platelet Activation

Published: December 2023

Platelets express several surface receptors that could interact with different viruses. To understand the mechanisms of HIV-1′s interaction with platelets, we chose the EcoHIV model. While EcoHIV is an established model for neuroAIDS, its effects on platelets are ill-defined. Our results indicate that EcoHIV behaves differently from HIV-1 and is cleared from circulation after 48 h post-infection. The EcoHIV course of infection resembles an HIV-1 infection under the effects of combined antiretroviral therapy (cART) since infected mice stayed immunocompetent and the virus was readily detected in the spleen. EcoHIV-infected mice failed to become thrombocytopenic and showed no signs of platelet activation. One explanation is that mouse platelets lack the EcoHIV receptor, murine Cationic Amino acid Transporter-1 (mCAT-1). No mCAT-1 was detected on their surface, nor was any mCAT-1 mRNA detected. Thus, mouse platelets would not bind or become activated by EcoHIV. However, impure virus preparations, generated by Polyethylene Glycol (PEG) precipitation, do activate platelets, suggesting that nonspecific PEG-precipitates may contain other platelet activators (e.g., histones and cell debris). Our data do not support the concept that platelets, through general surface proteins such as DC-SIGN or CLEC-2, have a wide recognition for different viruses and suggest that direct platelet/pathogen interactions are receptor/ligand specific.
Enhancing TB Vaccine Efficacy: Current Progress on Vaccines, Adjuvants and Immunization Strategies

Published: December 2023

Tuberculosis (TB) remains a global infectious disease primarily transmitted via respiratory tract infection. Presently, vaccination stands as the primary method for TB prevention, predominantly reliant on the Bacillus Calmette–Guérin (BCG) vaccine. Although it is effective in preventing disseminated diseases in children, its impact on adults is limited. To broaden vaccine protection, efforts are underway to accelerate the development of new TB vaccines. However, challenges arise due to the limited immunogenicity and safety of these vaccines, necessitating adjuvants to bolster their ability to elicit a robust immune response for improved and safer immunization. These adjuvants function by augmenting cellular and humoral immunity against M. tuberculosis antigens via different delivery systems, ultimately enhancing vaccine efficacy. Therefore, this paper reviews and summarizes the current research progress on M. tuberculosis vaccines and their associated adjuvants, aiming to provide a valuable reference for the development of novel TB vaccines and the screening of adjuvants.
A Novel Cellular Automata Framework for Modeling Depth-Averaged Solute Transport during Pluvial and Fluvial Floods
Authors: Wang Chia-Ho , Yu Hsiang-Lin , Chang Tsang-Jung
Published: December 2023

Currently, for modeling two-dimensional (2D) solute transport during pluvial and fluvial floods, the finite volume (FV) models are widely used because of their strong ability to handle steep concentration and velocity gradients from the flow advection term. However, heavy computational requirements are subsequently introduced which limit the numerical efficiency. To further increase numerical efficiency but keep the required accuracy, this study proposes a novel Solute Transport Modeling based on Cellular Automata framework (STMCA) to simulate solute transport due to the flow advection, turbulent diffusion, and material decay mechanisms in several sets of explicit algebraic equations. Four studied cases involving steep gradients of solute concentration and velocities in steady/unsteady violent flow conditions are used to compare the accuracy of the STMCA approach with a Godunov-type FV solute transport approach with a total variation diminishing (TVD) scheme. Then, the performances of the two approaches on water quality modeling are assessed through the E. Coli transport modeling during pluvial/fluvial floods on a real-scale terrain. The proposed STMCA approach is found to achieve almost the same accuracy as the FV approach. As to the numerical efficiency, the STMCA approach is faster than the FV approach by 289.6–328.6%. Hence, the proposed STMCA approach is proven to be an effective tool for simulating solute transport.
Research on Downstream Safety Risk Warning Model for Small Reservoirs Based on Granger Probabilistic Radial Basis Function Neural Network

Published: December 2023

Early warning of safety risks downstream of small reservoirs is directly related to the safety of people’s lives and property and the economic and social development of the region. The lack of data and low collaboration in downstream safety management of small reservoirs makes the existing safety risk warning methods for small reservoirs no longer fully applicable. The data from flood control and drought relief departments, small reservoir operation and management departments, etc., are used comprehensively. A machine learning model suitable for a large number of samples, a small amount of data, and the condition of incomplete information is applied and innovated, and from the holistic perspective of ‘upstream reservoir—downstream region’, the safety risk factors of the upstream reservoir are identified with the help of the Granger causality test. The risk losses of the disaster behavior are predicted with the three-dimensional k~ε two-equation model coupled with the VOF (Volume of fluid) method and the neural network model. The safety risk dynamics prediction, the prediction of the disaster-causing environment, and the prediction of the risk losses are integrated to construct the early warning method of the downstream safety risk of small reservoirs, and the simulation effect is verified with the example of the J Reservoir. The results show that the model can clarify the causal relationships and time lag dependencies between hydro-meteorological factors and the water level of small reservoirs, and calculate the inundation depth, inundation range, and flood velocity downstream of small reservoirs. The downstream safety warning model of small reservoirs constructed in this article can effectively integrate upstream and downstream information, further improve the timeliness and accuracy of warning, and provide a reference for downstream safety risk management of small reservoirs.

Large-scale particle image velocimetry (LSPIV) is a computer vision-based technique renowned for its precise and efficient measurement of river surface velocity. However, a crucial prerequisite for utilizing LSPIV involves camera calibration. Conventional techniques rely on ground control points, thus restricting their scope of application. This study introduced a near-field remote-sensing measurement system based on LSPIV, capable of accurately measuring river surface velocity sans reliance on ground control points. The system acquires gravity-acceleration data using a triaxial accelerometer and converts this data into a camera pose, thereby facilitating swift camera calibration. This study validates the system through method verification and field measurements. The method verification results indicate that the system’s method for retroactively deriving ground control-point coordinates achieves an accuracy exceeding 90%. Then, field measurements were performed five times to assess the surface velocity of the Datong River. These measured results were analyzed and compared with data collected from the radar wave velocity meter (RWCM) and the LS1206B velocity meter. Finally, a comprehensive sensitivity analysis of each parameter was conducted to identify those significantly impacting the river’s surface velocity. The findings revealed that this system achieved an accuracy exceeding 92% for all river surface velocities measured.
ПРИМЕНЕНИЕ КРЕЗАЦИНА ПРИ СИНХРОНИЗАЦИИ ПОЛОВОЙ ОХОТЫ ТЕЛОК КАЗАХСКОЙ БЕЛОГОЛОВОЙ ПОРОДЫ

Исследована возможность повышения эффективности фронтального осеменения телок при включении крезацина в схему синхронизации половой охоты. Для эксперимента сформировали 2 группы телок случного возраста казахской белоголовой породы по 40 голов в каждой. В обеих группах провели синхронизацию половой охоты по схеме Ovsynch. В опытной группе одновременно с гормональными препаратами телкам инъецировали раствор крезацина. При изучении динамики гормонов выявлено: в контрольной группе уровень прогестерона к 8-му дню опыта достоверно повысился на 32,7% по сравнению с исходным, а к 11-му — понизился на 82,2%. Уровень лютеинизирующего гормона (ЛГ), наоборот, к 8-му дню опыта снизился на 21,7%, а к 11-му (время осеменения) — повысился на 38,5%. В опытной группе динамика гормонов была аналогичной, однако значения изменений содержания гормонов были выше: к 11-му дню уровень прогестерона понизился на 87,1%, а уровень ЛГ повысился на 43,3%. Содержание свободного эстриола к моменту осеменения возросло в контрольной группе на 19,5%, а в опытной — на 61,9% (P<0,01). Следовательно, к 11-му дню от начала синхронизации в организме телок формируется наиболее благоприятное для овуляции сочетание прогестерона, эстрогенов и гонадотропинов. У телок опытной группы, получавших крезацин, положительные изменения уровня половых гормонов более выражены. В результате в опытной группе телок, получавших крезацин, оплодотворяемость от фронтального осеменения была на 10,0% выше. Это позволяет предположить участие крезацина в синтезе стероидных гормонов, регулирующих половой цикл у крупного рогатого скота.

Introducción al dossier: Reflexiones sobre la Modernidad política europea a partir del diálogo entre Antiguos y Modernos (ss. XVI-XVIII)
Authors: Saracino Maria Agostina , Vidal Silvina
Published: December 2023

El presente dossier se originó en la mesa temática “Reflexiones sobre la modernidad política europea y sus imperios: tradiciones, lenguajes e identidades (ss. XVI-XVIII)” que se desarrolló en el II Congreso de Ciencias Humanas de la Escuela de Humanidades de la Universidad Nacional de San Martín durante noviembre de 2022. Allí se dieron cita investigadores que, desde distintos ámbitos disciplinares (historia, ciencias políticas, filosofía y literatura), estudian los entramados conceptuales y los lenguajes que estructuran el espacio político euroamericano entre los siglos XVI y XVIII. Las cinco contribuciones reunidas aquí constituyen aproximaciones al estudio de las culturas políticas de la Europa temprano-moderna, a partir tanto del análisis de conceptos y prácticas considerados clave en la conformación de un espacio político euroamericano, como del impacto que tuvieron los procesos de recepción y reapropiación de los Antiguos ̶ en particular de las tradiciones grecorromana, hebrea y cristiana ̶ en la conformación de entramados conceptuales y lenguajes políticos
Infiltraciones de lo poético en la trilogía Whitelaw: Not I, Footfalls y Rockaby
Authors: Ferreira Fabio
Published: December 2023

En la Trilogía Whitelaw, compuesta por las obras Not I, Footfalls y Rockaby, se pueden identificar diversas manifestaciones líricas que se infiltran en las textualidades. Estas obras, dedicadas a las voces femeninas y en honor a la actriz Billie Whitelaw, muestran la génesis de los textos a través de la investigación de borradores y versiones iniciales disponibles en Beckett Achieves in Reading.
Se analizan las soluciones de autotraducción empleadas por Beckett, quien originalmente escribió los textos en inglés y luego los tradujo al francés. Las diferencias en la textualidad de los tres minidramas revelan posibles referencias a tradiciones y corrientes modernas, desde el epodo horaciano hasta la prosa poética de Octavio Paz, pasando por las páginas de Mallarmé, el verso libre surrealista y la prosa sonora de Louis Ferdinand Celine.
La transversalidad de géneros y las hibridaciones se acentúan en los textos finales, sellando definitivamente la presencia de la poesía a lo largo de la obra de Beckett, aunque esta faceta sea menos conocida en su rol como poeta.

Este trabajo tiene el objetivo de analizar cómo se producen y cambian el movimiento y el espacio en la poesía de Samuel Beckett, considerando las referencias a lugares y paseos específicos en los poemas de la primera fase de su producción en comparación con la creciente ausencia de esta movilidad y de las alusiones en los poemas posteriores a 1945. Además, se pretende observar la forma con que el movimiento se incorpora al lenguaje, a la construcción y a la forma en esos textos. Así, el análisis de poemas puede contribuir a la percepción de los contrastes entre el mundo exterior y el mundo interior en la obra. La discusión será guiada por la perspectiva de Theodor Adorno sobre las fases del modernismo. Entre los aspectos que se pueden leer en la producción de Beckett después de la Segunda Guerra Mundial, se destaca el tema de la inmovilidad y de la condenación al encierro en el espacio del cráneo, en el mundo interior, atravesado por la incertidumbre y la imprecisión de las palabras. Entonces se revela una faz distópica en la poesía final del autor – la desestabilización de las categorías de sujeto y sociedad, también expresa en la expropiación de la voz poética en su relación con el espacio. Esto culmina en una experiencia centrada en la mediación de los sentidos, las pulsiones y el lenguaje.
El Cantar de Mio Cid en la tradición de la Estoria de España: sobre la llamada Interpolación cidiana
Authors: Bautista Francisco
Published: December 2023

Este trabajo aborda el análisis de una de las piezas más enigmáticas de la tradición de la Estoria de España, conocida como Interpolación cidiana. Se trata del texto redactado para cubrir una laguna textual presente en el arquetipo de una importante familia de textos, que incluye la Versión amplificada, la Crónica manuelina y la Crónica de Castilla. Este texto abarca la parte final de la biografía cidiana, desde la conquista de Valencia, y presenta una redacción muy diferente de la redacción alfonsí de la Estoria de España, es decir, la Versión crítica. Se analiza aquí en particular el relato vinculado a la segunda parte del Cantar de Mio Cid, y trata de demostrar que depende de un poema similar al transmitido por el Códice de Vivar, probablemente a partir de la prosificación llevada a cabo en el taller de Alfonso X. A continuación, se estudia la sección correspondiente al Cantar de Corpes, que en este caso todo apunta a que depende de una refundición del poema conservado. Se plantea cuál pudo ser la fuente inmediata de esta parte y su inserción dentro del cuadro de la literatura cidiana de la segunda mitad del siglo XIII.

Diálogos interhistóricos: el Meister Eckhart de Michel Henry
Authors: Castello Sofia
Published: December 2023

Michel Henry ofrece un análisis de la propuesta metafísica de Meister Eckhart en los parágrafos §§39, 40 y 49 de su La esencia de la manifestación. Partiendo de los temas propuestos por M. Henry, el presente trabajo tiene como objetivo ampliar las consideraciones sobre estos al interior de la obra misma de Meister Eckhart. De esta forma, se puede apreciar el movimiento de recepción que el autor francés realizó: la construcción de una imagen de Eckhart que, aunque no se aleja demasiado de los puntos centrales de su teoría, con todo presenta ciertas omisiones que pueden hacer perder el carácter histórico del pensador alemán. Observar aquellos aspectos teóricos que Michel Henry decidió recuperar y los que decidió evitar es útil, a nivel de los diálogos interhistóricos, para observar qué elementos del neoplatonismo cristiano de Eckhart consideró aptos para incorporar a su sistema y cuáles, por el contrario, no encajaban en él.

En este artículo nos proponemos reflexionar sobre algunas de las experiencias concretas del Programa de Extensión Universitaria “Entramando Saberes” a la hora de comunicar públicamente conocimiento científico. Para eso, partiremos del caso de una producción audiovisual propia, siguiendo el camino que llevó a su realización, difusión y múltiples presentaciones al público. En este recorrido, nos referiremos a las producciones del equipo, a la articulación con otros grupos, a la incorporación de nuevos saberes y a las estrategias que desplegamos en función de los formatos y les participantes. Como argumento central, sostenemos que, lejos de ser prácticas disociadas, la investigación, la extensión y la docencia están en un continuum cuando se trata de producir y comunicar conocimiento científico.
Política lingüística poscolonial en África: el caso de Guinea Ecuatorial
Authors: Doppelbauer Max , Schlumpf Sandra
Published: December 2023

Este artículo presenta la historia de la política lingüística de Guinea Ecuatorial desde su independencia en 1968 hasta la actualidad. No solo en este campo nos encontramos con una complejidad difícil de explicar racionalmente. Las distintas constituciones de la Guinea Ecuatorial independiente no hacen sino revelar diferentes orientaciones dentro de la política lingüística, que a veces parecen oponerse entre sí. Una demarcación históricamente arbitraria, una sociedad multiétnica y un régimen intelectualmente desinteresado aumentan el grado de ingobernabilidad lingüística.
A Construção do ridículo político
Authors: Rodrigues Muniz Cellina
Published: December 2023

Em outubro de 2022, realizaram-se, em dois turnos, as eleições para presidente do Brasil. Em contexto de polarização política (KAKUTANI, 2018; KLEIN, 2021), os candidatos Jair Bolsonaro (PL) e Luís Inácio Lula da Silva (PT) disputaram o cargo em campanha que culminou com a vitória de Lula, representante da ala partidária e ideológica à esquerda, oposição ao governo de extrema-direita de Bolsonaro. Com a derrota, apoiadores de Bolsonaro, organizaram-se em atos que questionavam o resultado do pleito e exigiam anulação das eleições, acampando diante de quartéis das Forças Armadas. Surgem então textos humorísticos rebaixando esses atos e seus manifestantes, explorando aquilo que a filósofa Marcia Tiburi (2017) designa como ridículo político. São analisados três textos os quais, por meio de diferentes procedimentos humorísticos (POSSENTI, 1998), ilustram como suas cenografias enunciativas (MAINGUENEAU, 2006) apelam para um riso de zombaria (PROPP, 1992), principal elemento dessa construção discursiva do ridículo.
Dime de qué ríes y te diré quién eres
Authors: Fraticelli Damián
Published: December 2023

El artículo tiene por objetivo describir dos procedimientos del Humor Hipermediático en la generación y activación cotidiana de colectivos identitarios. Llamamos Humor Hipermediático a lo reidero producido en la interacción entre los medios de comunicación masiva y los medios con base en Internet y la telefonía (Fraticelli, 2023). El trabajo parte del abordaje semiótico del concepto de colectivo identitario de Verón (2013, 2012, 1997, 1994, 1987b) y su periodización del vínculo entre la conformación de colectivos y la mediatización. Luego, se hace foco en los cambios que trae el nuevo sistema mediático a la generación de colectivos, entre los que se encuentra la acción del Humor Hipermediático. De ella, nos concentramos en dos procedimientos básicos de la vida cotidiana: la producción de publicaciones risibles en las redes y la regulación de su circulación. Ambos producen la pertenencia a colectivos de identificación. Las maneras en que operan las describimos analizando dos casos. El primero es la producción de humor político hipermediatizado del primer discurso de apertura de las sesiones legislativas del presidente Alberto Fernández y del debate en el senado de la Ley de Interrupción Voluntaria del Embarazo. Y, el segundo es la regulación de la generación reidera del que fuera presidente de ArteBA, Juan Lynch, en la que actuaron distintos enunciadores hipermediáticos del mundo del arte y los medios informativos.
Desenmascaramiento y disolución del relato binario. La reescritura de "El matadero" y "La cautiva" de Esteban Echeverría en el teatro contemporáneo
Authors: Barbieri Analia
Published: December 2023

Las dramaturgias contemporáneas que reescriben a Echeverría retoman el relato binario de civilización/barbarie implícito en la cosmovisión de la juventud letrada rioplatense del siglo XIX. En el caso de Las cautivas, Mariano Tenconi Blanco narra una historia de amor entre dos mujeres que representan y problematizan dicha polarización, no sólo la de civilización/barbarie sino también el de género. Por otro lado, en la obra de Martínez Bel y Finamore, Olvidate del matadero, quien protagoniza la obra - un criado de la estancia de don Esteban- presencia la apertura del matadero al pueblo luego de una gran inundación. El relato pone en tela de juicio la dicotomía civilización/barbarie sugerida en la obra de Echeverría, y el conocimiento experiencial del nuevo narrador es legitimado como cultura popular.
Trabajar con lo que queda
Authors: Pellegrini Ana Lucía
Published: December 2023

En el presente trabajo propongo un análisis acerca del proceso creativo de la obra Nunca quise renunciar a mi carne (2020), dirigida junto a Sofía Rypka cuyo disparador gira alrededor del repertorio acumulado en los cuerpos y el concepto de “reconstrucción” llevado al recorrido individual de cada intérprete. La pregunta originaria de la obra que organizó tanto el proceso creativo como las diferentes temporadas y reposiciones de la obra estuvo dirigida entonces a aquello que conservaba cada intérprete de su propio recorrido y, a su vez, a aquello propio imposible de rastrear. Recurrimos a la propia memoria de los sucesivos procesos creativos acumulada en nuestros cuerpos con el objetivo de generar una mirada retrospectiva y crítica sobre este conjunto de experiencias pasadas, en diálogo con el análisis de una bibliografía alrededor de los conceptos de “archivo”, “repertorio”, “recreación” y “reconstrucción” que pusimos a prueba y deformamos para investigar nuestros propios lenguajes en la creación de una nueva pieza.  

A continuación describo las etapas del proceso creativo en diálogo con diversos autores, propongo una serie de reflexiones en el diálogo entre la investigación teórica y la práctica coreográfica y finalmente abro las claves para continuar en los próximos escritos.
Formas del docudrama en la ciudad de Córdoba
Authors: Brignone Germán
Published: December 2023

En la ciudad de Córdoba, un número significativo de espectáculos teatrales observados desde los primeros años del siglo XXI hasta la actualidad reformulan y actualizan de diversas formas el interés por la vinculación del teatro con lo real a partir de una investigación documental pre-dramática. El drama Mi nombre es Eva Duarte (M. Belén Pistone, 2019) se inscribe de manera destacada dentro de estas búsquedas, exhibiendo dichas tensiones a partir de la coincidencia de un nombre y de su carga simbólica en una vida, desnudando una historia que se imbrica con la Historia y se vuelve el reflejo de una búsqueda de lo identitario que trasciende la escena.
