Leveraging a Two-Level Attention Mechanism for Deep Face Recognition with Siamese One-Shot Learning
Authors: Albayati Arkan Mahmood , Chtourou Wael , Zarai Faouzi
Published: March 2024

Discriminative feature embedding is used for largescale facial recognition. Many image-based facial recognition networks use CNNs like ResNets and VGG-nets. Humans prioritise different elements, but CNNs treat all facial pictures equally. NLP and computer vision use attention to learn the most important part of an input signal. The inter-channel and inter-spatial attention mechanism is used to assess face image component significance in this study. Channel scalars are calculated using Global Average Pooling in face recognition channel attention. A recent study found that GAP encodes low-frequency channel information first. We compressed channels using discrete cosine transform (DCT) instead of scalar representation to evaluate information at frequencies other than the lowest frequency for the channel attention mechanism. Later layers can acquire the feature map after spatial attention. Channel and spatial attention increase CNN facial recognition feature extraction. Channel-only, spatial-only, parallel, sequential, or channel-after-spatial attention blocks exist. Current face recognition attention approaches may be outperformed on public datasets (Labelled Faces in the Wild).

Authors: Fazilat Mehdi , Zioui Nadjet
Published: March 2024

This research investigates the impact of model simplification on the dynamic performance of an ABB IRB-140 six-jointed industrial robotic arm, concentrating on torque prediction and energy consumption. The entire mathematical model of forward, reverse, differential kinematics, and dynamic model proposed based on the technical specifications of the arm, and to obtain the center of the mass and inertia matrices, which are essential components of the dynamic model, Utilizing Solidworks, we developed three CAD/CAM models representing the manipulator with varying detail levels, such as simplified, semi-detailed, and detailed. Our findings indicate minor differences in the model's torque and energy consumption graphs. The semi-detailed model consumed the most energy, except for joint 1, with the detailed model showing a 0.53% reduction and the simplified model a 6.8% reduction in energy consumption. Despite these variations, all models proved effective in predicting the robot's performance during a standard 30-second task, demonstrating their adequacy for various industrial applications. This research highlights the balance between computational efficiency and accuracy in model selection. While the detailed model offers the highest precision, it demands more computational resources, which is suitable for high-precision tasks. In discrepancy, simplified, less precise models offer computational efficiency, making them adequate for specific scenarios. Our study provides critical insights into selecting dynamic models in industrial robotics. It guides the optimization of performance and energy efficiency based on the required task precision and available computational resources. This comprehensive comparison of dynamic models underscores their applicability and effectiveness in diverse industrial settings.
EI-FRI: Extended Incircle Fuzzy Rule Interpolation for Multidimensional Antecedents, Multiple Fuzzy Rules, and Extrapolation Using Total Weight Measurement and Shift Ratio
Authors: Alzubi Maen , Almseidin Mohammad , Kovacs Szilveszter , Al-Sawwa Jamil , Alkasassbeh Mouhammd
Published: March 2024

Traditional fuzzy reasoning techniques demand a condensed fuzzy rule base to conclude a result. Still, due to incomplete data or a deficiency of expertise and knowledge, dense rule bases are not always available. Fuzzy interpolation methods have been widely explored to reasonably allow the interpolation of a fuzzy result using the closest current rules. Fuzzy rule interpolation is a type of fuzzy inference system in which conclusions can be obtained even with a few fuzzy rules. This benefit could be used to adapt the FRI to different application areas that suffer from a lack of knowledge. Alzubi et al. [17] offered a novel interpolative method that uses a weighted average based on the center point of the Incircle of the fuzzy sets. Nevertheless, the interpolated observation does not completely define the actual observation that is provided. In our offered extension to this method, a modification weight measure calculation and a shift technique are included to guarantee that the center point of the observation and the interpolated observation are mapped together. This weight measure calculation and shift technique enabled the capability of extrapolation to be conducted implicitly, which is also improves the performance results of the algorithm in the presence of multiple fuzzy rules and multidimensional priors.
Addressing Challenges in Dynamic Modeling of Stewart Platform using Reinforcement Learning-Based Control Approach
Authors: Yadavari Hadi , Aghaei Vahid Tavakol , İkizoğlu Serhat
Published: March 2024

In this paper, we focus on enhancing the performance of the controller utilized in the Stewart platform by investigating the dynamics of the platform. Dynamic modeling is crucial for control and simulation, yet challenging for parallel robots like the Stewart platform due to closed-loop kinematics. We explore classical methods to solve its inverse dynamical model, but conventional approaches face difficulties, often resulting in simplified and inaccurate models. To overcome this limitation, we propose a novel approach by replacing the classical feedforward inverse dynamic block with a reinforcement learning (RL) agent, which, to our knowledge, has not been tried yet in the context of the Stewart platform control. Our proposed methodology utilizes a hybrid control topology that combines RL with existing classical control topologies and inverse kinematic modeling. We leverage three deep reinforcement learning (DRL) algorithms and two model-based RL algorithms to achieve improved control performance, highlighting the versatility of the proposed approach. By incorporating the learned feedforward control topology into the existing PID controller, we demonstrate enhancements in the overall control performance of the Stewart platform. Notably, our approach eliminates the need for explicit derivation and solving of the inverse dynamic model, overcoming the drawbacks associated with inaccurate and simplified models. Through several simulations and experiments, we validate the effectiveness of our reinforcement learning-based control approach for the dynamic modeling of the Stewart platform. The results highlight the potential of RL techniques in overcoming the challenges associated with dynamic modeling in parallel robot systems, promising improved control performance. This enhances accuracy and reduces the development time of control algorithms in real-world applications. Nonetheless, it requires a simulation step before practical implementations.

Functional electrical stimulation (FES) is a medical device that delivers electrical pulses to the muscle, allowing patients with spinal cord injuries to perform activities such as walking, cycling, and grasping. It is critical for the FES to generate stimuli with the appropriate controller so that the desired movements can be precisely tracked. By considering the repetitive nature of the movements, the learning-based control algorithms are utilized for regulating the FES. Iterative learning control (ILC) and repetitive control (RC) are two learning algorithms that can be used to accomplish accurate repetitive motions. This study investigates a variety of ILC and RC designs with distinct learning functions; this constitutes our contribution to the field. The FES model of ankle angle, which is in a class of discrete-time linear systems is considered in this study. Two learning functions, i.e., proportional, and zero-phase learning functions, are simulated for the second-order FES model running at a sampling time of 0.1 s. The results indicate the superior performance of the ILC and RC in terms of convergence rate using the zero-phase learning function. ILC and RC with a zero-phase learning function can reach a zero root-mean-square error in two iterations if the model of the plant is correct. This is faster than proportional-based ILC and RC, which takes about 40 iterations. This indicates that the zero-phase learning function requires two iterations to ensure that the patient's ankle angle precisely tracks the intended trajectory. However, the tracking performance is degraded for both control methods, especially when the model is subject to uncertainties. This specific problem can lead to future research directions.

Authors: Kumari Priyanka , Swati  , Kumar Ashutosh , Gunjan Gunjan
Published: March 2024

Background: Eclampsia, characterized by seizures in women with preeclampsia, is a leading cause of mother and neonatal illness and death globally. Despite advancements in obstetric care, eclampsia remains a significant concern, especially in nations with poor and medium incomes. The aim of the study is to comprehensively assess the maternal and perinatal outcomes associated with eclampsia cases treated at a tertiary healthcare centre with the goal of improving understanding and management strategies for this serious medical condition.
Methods: This retrospective observational study was conducted over 12 months. Data were collected from 200 eclampsia cases, focusing on demographic information, obstetric history, clinical characteristics, obstetric interventions, maternal complications, and perinatal outcomes. Statistical analysis was accomplished using SPSS version 21.
Results: The mean age of patients was 28.5 years, with a majority (65%) being multiparous. Antepartum eclampsia was the most common clinical type (60%). Emergency caesarean section was performed in 70% of cases. Maternal complications included pulmonary edema (45%) and renal failure (25%), with a maternal mortality rate of 5%. Pre-term births occurred in 40% of cases, with an average gestational age at birth of 32 weeks. Additionally, 35% of newborns were low birth weight, and the perinatal mortality rate was 15%.
Conclusions: This study highlights the substantial burden of neonatal and mother morbidity and death related with eclampsia in Bihar, India. Effective management strategies, including timely diagnosis, obstetric interventions, and preventive measures, are crucial in mitigating the adverse outcomes of eclampsia. Improving access to antenatal care, early detection of pre-eclampsia, and enhancing obstetric care services are essential in reducing the impact of eclampsia. Furthermore, continuous medical education programs for healthcare providers can enhance their knowledge and skills in managing eclampsia cases effectively.

Authors: Polikarpova Aleksandra , Lau Ngee-Soon , Coker David J.
Published: March 2024

Spontaneous pneumomediastinum (SPM) is a condition characterised by presence of air in the mediastinum that is not iatrogenic or secondary to trauma. We conducted a retrospective review of 4 cases, treated at our hospital for SPM in 2023. The mean age of the patients was 35 years (range, 28-58 years), with 3 male (75%). Only one of the patients (25%) had precipitating projectile vomiting followed by hematemesis. Chest pain was by far the most common symptom (75%). One patient presented with haematemesis, raised inflammatory markers and fever. Pneumomediastinum was diagnosed by plain chest radiography in all cases. In all cases a computed tomography (CT) scan of the chest with on table contrast was performed with half of the patients needing fluoroscopy swallow later in the admission. Half of the patients were treated for suspected oesophageal perforation and received antibiotics and kept nil by mouth, the other two patients only required supportive care. The mean length of hospital stay was 3.4 days (range, 1.2-4.7 days). SPM is a benign process primarily affecting young otherwise healthy males. There is a growing body of evidence to suggest that CT of the chest with on table contrast should be reserved for patients presenting with red flags such as abdominal pain, hematemesis, fever and raised inflammatory markers.

Aim of this study is to analyse the prevalence and pattern of cutaneous manifestations among type 1 and type 2 DM correlating it with the mean duration of diabetes.

This was an observational study conducted on 200 consecutive patients with DM attending dermatology department. Apart from detailed history, thorough clinical examination and relevant investigations were done. Skin biopsy were done in cases with diagnostic ambiguity.

Cutaneous infections occurred in majority (70.5%). Among fungal infections (59.5%) candidiasis was the most common (28%). Pruritus and neuropathy were observed in 37% and 33% respectively and was more common in type 1 DM. Leg ulcer was observed in 8.5%. Vitiligo, oral lichen planus, granuloma annulare were seen common among type 1 DM. Psoriasis, acrochordon, acanthosis nigricans, cutaneous amyloidosis, bullous pemphigoid and diabetic bulla were common in Type 2 DM. Mucor mycosis, scleredema diabeticorum, cheiroarthropathy and perforating dermatoses were uniquely observed among prolonged uncontrolled diabetics.

Candidiasis was found to be an early manifestation of diabetes. Poor glycemic control and longer duration of diabetes were associated with an increased frequency and number of skin disorders. Skin manifestations are more common among undiagnosed and uncontrolled diabetics..

Antibiotics are the crucial drugs of choice, and they are the greatest contributors to the treatment of bacterial skin diseases. The objective of the present study is to assess the drug usage patterns of antibiotics in the Department of Dermatology, Venereology, & Leprosy (DVL).

A Cross-Sectional Study was conducted with ethical approval for a period of 6 calendar months. Patients were recruited according to the eligibility criteria. Relevant details were collected according to the objectives and analyzed using Microsoft Excel.

During the study period, 200 patients were recruited, of which 64% were male. Most patients were in the age group of 21-40 (36%). The most commonly reported disease during our study was secondary pyoderma occurring over eczema (29.5%), followed by Psoriasis (9.5%). Penicillin (32%) and Cephalosporin (32%) were the most prescribed categories. Mainly, a duration of less than or equal to 1 week was recommended. A total of 680 drugs were prescribed, and the average number of drugs per encounter with an antibiotic was 4.50%. The percentage of encounters with injections was 12%, and the percentage of medicine from the Essential Medicine List (EML) was 43%. Most drugs were prescribed from the access groups according to the World Health Organization (WHO) AWARE (Access, Watch, Reserve) classification.

According to the AWARE classification, drugs with lower resistance potential were commonly practiced here. This reflects good prescribing practice. The findings provide insight that, during our study period, the burden of bacterial skin diseases is lower in this locality when compared with other skin diseases.

The rationality of using ash and slag waste from coal-fired TPP to obtain high-quality iron-containing concentrate (FC) is demonstrated. Using the method of wet magnetic separation of ash and slag waste from TPP, FC is extracted with Fe2O3 content of 59.2 %. It has been established that the method of chemical enrichment with ammonium hydrofluoride can increase the Fe2O3 content in FC to 79 %; a by-product of the reaction between FC and NH4F•HF is high-quality amorphous silica (white soot). The effect of process temperature on the composition of the resulting FC has been studied, at that the phase composition of iron oxides remains virtually unchanged. Optimal modes of the process are proposed.

The actual study of ethnic identity is conditioned by the previous socio-political context. In the West, attention to ethnic identity is a marker of post-colonial studies, while in Russia it is a departure from the formation of a new historical community "Soviet people". Accordingly, the cognitive goals of studying ethnic identity also differ from the manipulation of ethnic identities, leading to the split in a previously unified society, to identifying factors that contribute to the preservation of ethnic minority cultures. Defining the content of ethnic identity as consisting of cognitive and behavioral components makes it possible to use the concepts of "ethnic identity" and "ethnicity" as synonyms. The instrumentalist approach combining the ideas of primordial and constructivist concepts was used in a concrete sociological study of the ethnic identity of the aboriginal people. The hypothesis put forward by the study about the threat to the ethnic identity of the minorities from the processes of globalization was confirmed, but required clarification. The influence of globalization on ethnic identity is indirect; the dominant national culture acts as a buffer between them.
The image of the “alien” in the infrastructure of the Russian city (the example of Chelyabinsk region)
Authors:   South Ural State University (National Research University), Salganova Elena I.
Published: March 2024

The article aims to identify the criteria of the "image" of a migrant and "migrant" infrastructure, to describe the problems of interethnic relations, integration of migrants from Central Asia in a Russian city (using the examples of cities in Chelyabinsk region). The author relies on 540 interviews with the local population of six cities of the region (Chelyabinsk, Kopeysk, Magnitogorsk, Miass, Zlatoust, Troitsk), as well as the results of observations, content analysis of mass media and Internet resources. The quantitative and qualitative characteristics revealed in the course of the research allowed us to characterise the image of the "alien", the structure of urban space in the dichotomy "native"-"alien", to identify the problems of interethnic relations, to describe which objects are given the status of "migrant" and through what markers this happens. Particular attention is paid to the image of the "alien" in the media and various Internet resources, which largely shape public attitudes towards migrants and where the latter are most often endowed with negative characteristics (settling by large families and thus "taking over" entire city districts, illegally occupying jobs and entire spheres of the regional economy). It is concluded that the image of the "alien" and "migrant" infrastructure in the media is formed under the influence of national, ethnic and class stereotyping, a limited set of life contexts, impersonality and passivity of migrants. It was revealed that a significant part of negative attitudes of the local population towards migrants is projected onto quite specific objects of urban infrastructure (markets, educational and medical institutions, "dangerous" neighbourhoods, etc.) and the spheres of activity (shuttle buses, trade, construction, etc.).

The content of the political image of one of the regional Russian leaders during the electoral period (elections of heads of Russian constituent entities in 2023) is studied in the article. The purpose of the paper is to identify the features of the symbolic and semantic content of the network image of a regional political leader during the pre-election period. Fulfillment of the set research goal is carried out using the concept of the image-role construct and methods of content analysis (qualitative-quantitative type) and comparative analysis. The information array is consisted of text records posted on the official website of the Governor of the Nizhny Novgorod Region G. S. Nikitin on “VKontakte” and in his Telegram-channel, for the period from May to September 2023. Based on the results of the study, it was revealed that the most popular image-role construct on both Internet platforms was “economic manager”. Next in frequency of occurrence are such constructs as “team player”, “a leader who is aware of various details of current problems» and «a leader looking to the future”. The conclusion was made about the closeness of the occurrence frequency indicators of different symbolic and semantic constructs within the image of a leader presented within the two indicated network communication channels (on the official page on “VKontakte” and in the Telegram-channel).

Covid Collective Learning Report
Authors: Taylor Joe , Taylor Peter , Clark Louise
Published: March 2024

This report provides an overview the Covid Collective research platform, how it was operationalised, and the learning which emerged from the three-year programme. The foundation of the Covid Collective’s theory of change was the network and relationships that were established and developed to harness collaboration and sharing of knowledge across a platform of global research partners. We acknowledged the critical role knowledge sharing, learning and engagement played in creating a culture that could enable and catalyse evidence-based, transformative action in response to Covid-19. The network that was developed in forming the Covid Collective could then facilitate comparative learning and collective action, and generate new insights and knowledge on the factors that support more or less effective responses to Covid-19 and help to build resilience to address future global development challenges.
Comparative decay resistance of plantation-grown and naturally-grown teak wood (Tectona grandis L.f.)
Authors: YAMAMOTO Koichi
Published: March 2024

Teak (Tectona grandis L.f.) is one of the most popular tropical timber species for its natural durability. The sapwood, the outer, middle, and inner heartwood, and the pith of plantation-grown teak in Indonesia and naturally grown teak in Myanmar were tested for decay resistance (a major component of natural durability), applying an accelerated decay test according to JIS Z 2101 (1994), and using a white rot fungus (Trametes versicolor) and a brown rot fungus (Fomitopsis palustris). Wood blocks 20 × 20 × 10 mm in size were cut from discs across the radius of the stem. The percentage mass loss in each block caused by decay was obtained after 12 weeks of incubation with these fungi. Mean mass losses due to T. versicolor were respectively as follows for plantation-grown, naturally-grown (No. 1), and naturally-grown (No. 2) teak: sapwood 21.4%, 7.1%, “no data”; outer heartwood 0.6%, 3.6%, 6.6%; middle heartwood 2.3%, 6.5%, 5.7%; inner heartwood 10.3%, 9.6%, 6.0%; pith 13.0%, 15.3%, 8.2%. Losses due to F. palustris were, respectively: sapwood 7.5%, 3.0%, 7.5%; outer heartwood 0.0%, 2.5%, 2.7%; middle heartwood 0.0%, 2.2%, 2.3%; inner heartwood 4.9%, 2.0%, 3.4%; pith 13.6%, 8.4%, 8.0%. Durability was classified with reference to Osborne (1970), based on the mean percentage weight loss of heartwood caused by fungal decay. Only the outer and middle heartwood were generally durable in both plantation-grown and naturally grown teak specimens. The inner heartwood was moderately durable, but pith durability was low. No clear differences in decay resistance were found between plantation-grown and naturally-grown teak.

Understanding Spontaneous Symbolism in Psychotherapy Using Embodied Thought
Authors: Goodwyn Erik D
Published: March 2024

Spontaneous, unwilled subjective imagery and symbols often emerge in psychotherapy that can appear baffling and confound interpretation. Moreover, early psychoanalytic theories seemed to diverge as often as they agreed on the meaning of such content. Nevertheless, reviewing key findings in the empirical science of spontaneous thought, as well as insights gleaned from neurosciences and especially embodied cognition, it is now possible to construct a more coherent theory of interpretation that is clinically useful. Given that thought is so thoroughly embodied, it is possible to demonstrate that universalities in human physiology yield universalities in thought. Such universalities can then be demonstrated to form a kind of biologically directed universal “code” for understanding spontaneous symbolic expressions that emerge in psychotherapy. An example is given that illustrates how this can be applied to clinical encounters.
A Demand-Side Response Optimization Method for Flexible Loads Considering the Benefits of Peak-to-Valley Smoothing
Authors: Shi Sichen , Wang Peiyi , Zheng Zixuan , Zhang Shu
Published: March 2024

To satisfy the interests of multiple agents and those of comprehensive indicators such as peak-to-valley differences and load fluctuations occurring on the network side, this paper presents a flexible load demand-side response optimization method that considers the benefits of peak-to-valley smoothing. First, load aggregation modelling of air conditioning and electric vehicles was conducted, and the complementarity of the power consumption behaviour of different types of flexible loads was used to improve the responsiveness of the load aggregator. Second, considering demand-side responses and taking into account the interests of both supply and demand, the load fluctuation and peak-to-valley difference on the network side are reduced, and a flexible load double-layer optimization model incorporating the peak-to-valley smoothing benefit is established. Finally, the effectiveness of the proposed optimization model is verified by using the KKT condition and the big M method to evaluate this two-layer optimization problem as a single-layer optimization problem. Comparative examples demonstrate that the proposed two-layer optimization method can improve the revenue of the distribution network operators and the load aggregators by using the complementary nature of the load response characteristics of electric vehicles and air conditioners. Moreover, the proposed method can effectively reduce the load peak-to-valley difference and load fluctuation of the distribution network by introducing the peak-to-valley smoothing benefit model.
No Evidence Of Sensory Neuropathy In A Traditional Mouse Model Of Idiopathic Parkinson’s Disease
Authors: Faisal Mahvish , Rusetskaya Anna , Vali Liis , Taba Pille , Minajeva Ave , Hickey Miriam A
Published: March 2024

Parkinson’s disease (PD) is the second-most common neurodegenerative disorder worldwide and is diagnosed based upon motor impairments. Non-motor symptoms are well-recognized in PD, and peripheral neuropathy is a frequent but poorly appreciated non-motor sign. Study of how the central and peripheral sensory systems are affected can contribute to the development of targeted therapies and deepen the understanding of the pathophysiology of PD. Although the cause of sporadic PD is unknown, chronic exposure to the pesticide rotenone in humans increases the risk of development of PD. Here, we aimed to investigate whether peripheral neuropathy is present in a traditional model of PD. Mice receiving intrastriatal rotenone showed greatly reduced dopamine terminals in the striatum and reduction in tyrosine hydroxylase-positive neurons in the Substantia nigra pars compacta and developed progressive motor impairments in hindlimb stepping and rotarod but no change in spontaneous activity. Interestingly, repeated testing using gold-standard protocols showed no change in gut motility, a well-known non-motor symptom of PD. Importantly, we did not observe any change in heat, cold, or touch sensitivity, again based upon repeated testing with well-validated protocols that were statistically well-powered. Therefore, this traditional model fails to replicate PD, and our data again reiterate the importance of the periphery to the disorder that is PD.
PARP-Targeted Radiotheranostics with Auger Electrons: an Updated Overview
Authors: Filippi Luca , Urso Luca , Evangelista Laura
Published: March 2024

Auger electrons (AEs) represent an intriguing topic in the field of radionuclide therapy. They are emitted by several radionuclides commonly used in nuclear medicine (indium-111, iodine-123, iodine-125), allowing for highly localized energy deposition and thus exerting a radiotoxic effect on specific cellular and sub-cellular targets. However, due to their short range in matter, AEs have had limited use in therapeutic applications so far. In recent years, the synthesis of various radiopharmaceuticals capable of binding to the enzyme poly(ADP-ribose) polymerase 1 has reignited interest in this type of therapy, laying the groundwork for a theranostic approach based on radionuclides emitting AEs. The enzyme PARP-1 operates enzymatically in close proximity to DNA that represents the prime target of radionuclide therapies. Following this trend, several PARP-targeted radiopharmaceuticals for AE-based theranostics have been developed. We provide an updated overview of preclinical studies focused on the applications of this new theranostic approach in glioblastoma, breast, prostate and ovarian carcinoma, and pancreatic adenocarcinoma.

El duelo de la crisis sanitaria
Authors: Estrada Álvarez Carlos Mario
Published: March 2024

El presente documento se elabora con la finalidad de crear una reflexión sobre la situación actual de la pandemia ocasionada por el Covid-19 siendo esta fenómeno que permite estudiarlo a partir de la teoría del Duelo de Elizabeth Kübler- Ross. Se revisaron fuentes bibliográficas como libros y sitios Web que permitieran desarrollar un sustento teórico sobre el estado actual de la pandemia y el proceso de duelo que de este se desprende. En este trabajo se puede comparar que actualmente vivimos un estado de crisis que nos lleva a elaborar un duelo de forma personal o colectivo sobre la situación que vivimos dia a dia. Se necesita ser más empáticos y entender que posiblemente no todos nos encontremos en el mismo fase de duelo, unos en sus inicios y otros aceptando la situación, sin embargo no deja de ser un problema que nos afecta a la mayor parte de las personas en todo el mundo.
La Cruel Pedagogía del Virus
Authors: Suárez Elías Mariano
Published: March 2024

La Cruel Pedagogía del Virus forma parte de una nueva colección de textos breves editada por CLACSO y orientada a dar respuestas a problemas de nuestro tiempo. El libro, que sale a la luz en mayo de 2020, es escrito por uno de los autores más influyentes de la teoría crítica contemporánea, el portugués Boaventura de Sousa Santos. Pese a que la idea central es que el virus enseña de manera cruel, se podría decir que la interpretación de lo que está sucediendo es también un terreno de lucha en donde los movimientos sociales y partidos de izquierda deben participar activamente disputando la interpretación a las visiones conservadoras. En ese sentido, este libro debe ser leído como una contribución que se hace en plena pandemia a la interpretación de las implicancias sociales de lo que está sucediendo y las posibilidades de acción transformadora que se abren a partir de ello.
