Published: January 2025

In this paper, we studied the effect of strontium doping on the structural, microstructural, dielectric, and electrical properties of Ba1-xSrxTiO3 (BSxT) ceramics prepared via the sol-gel method, with x = 0.00 to 0.15. The results obtained from the X-ray diffraction spectrum confirmed the creation of the pure perovskite structure, with the diffraction peaks of the BSxT shifting toward the bigger 2θ with increasing Sr content. Scanning electron microscopy images show that the grain size of the BSxT ceramics decreases with increasing Sr content. An increase in Sr content appears to lower the activation energy by the factor of 0.16 meV/mol% and to decrease Curie temperature by the factor of 3.34 °C/mol%. Furthermore, in case of 15 mol% of Sr addition, the dielectric constant value is increased about twice. Moreover, the relationship between grain sizes and dielectric properties was also investigated. Using the frequency measurement method (up to 2 MHz in a step of 1 kHz), we are able to determine the temperature of transition without using the conventional method.

Over the last several decades, advancements in industry have facilitated the absorption of harmful gases into the bloodstream or lungs via dermal absorption or inhalation. This process may elicit diverse cellular responses, potentially leading to adverse health effects. Consequently, air pollution has emerged as a significant worldwide issue. Hence, developing a device capable of monitoring air pollution and detecting these chemicals in the surrounding environment became imperative. Gas sensors are instruments used for regulating industrial emissions, surveillance of environmental contaminants, and identification of pollutants and hazardous gases. Semiconductor gas sensors have garnered significant recognition owing to their several advantageous characteristics, including simplified production processes, compact dimensions, and low-cost. Some of its drawbacks include limited selectivity and high operating temperatures. This review discusses the most often used semiconducting materials in gas sensing, as well as the methods used to synthesize them, and the reduction and oxidation processes that happen between metal oxides and analyte gas. Furthermore, the various strategies employed to increase the gas-sensing response are explored, such as doping with noble metals and the formation of heterostructures.
Chemical Profiling Ethyl Acetate Extract of Basilicum polystachyon Leaves and Exploration of Anticancer SIRT1 Inhibitors Using In Silico Approach
Authors: Tukiran Tukiran , Raihan Muhammad
Published: January 2025

Cancer significantly increases prevalence and mortality rate making it a serious health concern currently, including breast cancer. The development of new drugs is a major effort to solve the cancer problems. Natural products are the primary source of medicinal compounds believed to have lower toxicity and side effects than synthetic drugs. This research aimed to reveal the chemical profile of the ethyl acetate extract of Basilicum polystachyon leaves. Through an in silico approach, this research studied the anticancer mechanism against the sirtuin1 (SIRT1) at the molecular level. Molecular docking simulations were performed to understand the interaction behavior of potential compounds as SIRT1 inhibitors. Based on these results, 117 individual compounds were successfully identified in the ethyl acetate extract. Molecular docking simulation revealed that ten compounds could inhibit SIRT1 better than the control inhibitor, indicating that these compounds have potential as anticancer agents. The prediction of these compounds' physicochemical properties and pharmacokinetics showed promising results and fulfilled the medicinal compound's criteria. These findings can be the basis for the application of phytochemical compounds as anticancer drugs, specifically potential compounds in B. polystachyon leaves.
A Palimpsestic Narrative Of The Chinese Settlement In Calcutta
Authors: Aby Athulya
Published: January 2025

“Self-imposed invisibility is the distinct characteristic of Kolkata's Old Chinatown today” (Bose, 2016). Yet, their presence in the city is strongly felt through the Chinese breakfast street of Tiretta bazaar, hand-made leather shoe-shops in Bentick Street, Chinese owned beauty parlours and laundromats, and the week long festivities of the Chinese New Year. Though the diaspora has maintained a cultural specificity by means of temples, clubs, schools and newspaper presses, their aspiration to assimilate is evident in their built environment. In Calcutta, the often-overlooked stories of the Chinese settlements highlight a hidden side of the city's architecture. Through the spatial study of the two Chinatowns – Cheenapara, within the CBD, and Tangra, on the outskirts – this study explores the indicators of assimilation and assertion of identity of the Chinese diaspora in the city.
It delves into the hidden, yet pivotal spatial practices that reveal a complex interplay of inclusion, exclusion, and displacement—factors often overshadowed by the physicality of architecture. The essay is the result of the research conducted during my master's program in Architectural History and Theory from CEPT University, India, under the guidance of Dr. Sonal Mittal. The research foregrounds the intangible heritage of the Chinese in Calcutta, through a meticulous exploration of archival documents and histographical maps. By transcending the traditional architectural narrative that prioritizes tangible outcomes, this paper argues for a recognition of the invisible actants—stories, myths, and archived narratives—that mold the unseen architecture of community identity and memory. Through this lens, the paper contributes to an understanding of architecture not merely as a physical artifact but as a repository of underrepresented narratives and contested heritage, challenging the borders of conventional architectural discourse and advocating for a broader, more inclusive historiography that recognises forgotten labours and decolonial approaches.
Fundamental charges for dual-unitary circuits
Authors: Holden-Dye Tom , Masanes Lluis , Pal Arijeet
Published: January 2025

Dual-unitary quantum circuits have recently attracted attention as an analytically tractable model of many-body quantum dynamics. Consisting of a 1+1D lattice of 2-qudit gates arranged in a 'brickwork' pattern, these models are defined by the constraint that each gate must remain unitary under swapping the roles of space and time. This dual-unitarity restricts the dynamics of local operators in these circuits: the support of any such operator must grow at the effective speed of light of the system, along one or both of the edges of a causal light cone set by the geometry of the circuit. Using this property, it is shown here that for 1+1D dual-unitary circuits the set of width-w conserved densities (constructed from operators supported over w consecutive sites) is in one-to-one correspondence with the set of width-w solitons – operators which, up to a multiplicative phase, are simply spatially translated at the effective speed of light by the dual-unitary dynamics. A number of ways to construct these many-body solitons (explicitly in the case where the local Hilbert space dimension d=2) are then demonstrated: firstly, via a simple construction involving products of smaller, constituent solitons; and secondly, via a construction which cannot be understood as simply in terms of products of smaller solitons, but which does have a neat interpretation in terms of products of fermions under a Jordan-Wigner transformation. This provides partial progress towards a characterisation of the microscopic structure of complex many-body solitons (in dual-unitary circuits on qubits), whilst also establishing a link between fermionic models and dual-unitary circuits, advancing our understanding of what kinds of physics can be explored in this framework.

The Focus Group method is one of the few traditional methods used in qualitative research. There has been much debate
in scientific circles about its suitability and the validity of the
data it produces. This method was often seen as more of a
complementary one. Currently, according to Miovský (2006),
this research method is used in sociology and marketing research. The popularity of this method has increased in recent
years, and when chosen for the right purpose, it can also bring
good results.

Are Regular Aerobic Exercisers With Type 1 Diabetes Following Current Physical Activity Self-Management Guidelines? Insights From an Online Survey
Authors: Henske Joseph , Albashaireh Arwa , Turner Lauren V. , Beach Gavin , Riddell Michael C.
Published: January 2025

This study surveyed 102 adults with type 1 diabetes who were a part of online communities for regular exercisers with type 1 diabetes. These individuals, who met or exceeded aerobic exercise guidelines, were evaluated via self-report for their adherence to recommended glucose management strategies before, during, and after physical activity. Although most reported using diabetes-related technologies, 86% of respondents reported having frequent activity-related hypoglycemia. Eighty percent reported using trial-and-error strategies, and only 32% identified their health care professionals as a key source of exercise self-management education. Few followed consensus-based guidelines such as reducing insulin doses before exercise and refraining from exercising within 24 hours after a severe hypoglycemic event.

INTRODUCTION: Pelizeaus–Merzbacher disease is an orphan disorder caused by a mutation in the PLP1 gene, linked with X chromosome. Its incidence is 1.4–1.9 per 100 thousand people in the general population. The disease is a hereditary leukodystrophy which predominantly affects the central nervous system (CNS) and is characterized by a sharp decrease or absence of myelin sheaths in the white matter areas of the CNS. Impaired neuromuscular conduction, reduced muscle tone may lead to scoliotic spinal deformation including that of a very severe degree.
The article describes methodical approaches to surgical correction, anesthetic support and postoperative management of a patient with Pelizeaus–Merzbacher disease taking into account the pathogenetic features of a rare nosological form.
CONCLUSION. The presented clinical case demonstrates the possibility of successful provision of anesthetic support and early postoperative management of a patient with a rare severe pathology. A thorough preoperative examination including spirometry and echocardiography, permitted to identify potential problems in the postoperative period and prevent them. The use of modern blood conservation methods and online monitoring of hemoglobin level provided stable hemodynamics and tissue oxygenation throughout the entire intervention.

INTRODUCTION: Catheter radiofrequency or cryoablation operations in accordance with the existing recommendations are one of the main methods of treatment for atrial fibrillation (AF). However, in some cases, pulmonary vein isolation is not sufficient to effectively control arrhythmia, and linear ablations are required in the left atrium during the operation. Despite increased effectiveness of such ablations to prevent AF recurrences, a significant problem in this group of patients is incisional atrial flutter. The critical zone for incisional left-atrial arrhythmias in the vast majority of patients is the mitral isthmus due to its anatomical and electrophysiological features. At the same time, mitral isthmus ablation is associated with technical difficulties due to thickness of the myocardium in this zone, complex anatomical structure of this region and a cooling effect of blood flow in the circumflex branch of the left coronary artery with the probability of reaching the conduction block in 40%–80% of cases.
The operation of alcohol ablation of the mitral isthmus proposed by M. Valdebarano, et al. is an effective additional tool for treating the perimitral atrial flutter and achieving the conduction block in it. The clinical case presented by us shows the effective use of this operation in a patient after several cryo and radiofrequency ablation procedures AF for the treatment of perimitral atrial flutter refractory to other methods.
CONCLUSION: Alcohol ablation of the vein of Marshall can be an effective tool for the treatment of perimitral atrial flutter in patients with several past cryo and radiofrequency ablations in the left atrium.
Estimated cumulative incidence of intervention by children's social care services to age 18: a whole-of-England administrative data cohort study using the child in need census
Authors: Jay Matthew A , Troncoso Patricio , Bilson Andy , Thomson Dave , Dorsett Richard , Pearson Rachel , De Stavola Bianca , Gilbert Ruth
Published: January 2025

IntroductionEach year, children's social care (CSC) recognises around 3% of all children as children in need (CiN) of intervention, including those who receive a child protection plan due to risks of substantial harm and those who become looked after in state care. A previous cumulative estimate of the incidence of becoming CiN of 14% to age 5 indicates that the childhood lifetime incidence is likely very high.
ObjectivesWe aimed to estimate the cumulative incidence of referrals, social work assessments, being recognised as a CiN or made subject to a child protection plan (CPP) before age 18 in England.
MethodsThe annual CiN census contains all-of-England longitudinal records of CSC referrals. Data collection began in 2008, meaning there is no cohort that can be followed up from birth to age 17 (i.e., before 18th birthday). Analyses revealed data quality issues before 2011/12. We estimated the above cumulative incidences in three cohorts and combined them, adjusting numerators to account for left-censoring. The three cohorts were children born in: (a) 2012/13, followed to age 5; (b) 2005/06, followed from age 6 age to 12; and (c) 2000/01, followed from age 13 to 17. We carried out sensitivity analyses to address possible bias induced by linkage error using one of two encrypted identifiers in the dataset.
ResultsOf all children living in England, before turning 18, 35.4% were referred, 32.3% were assessed, 25.3% were recorded as CiN and 6.9% were subject to a CPP (37.5%, 34.6%, 26.0% and 7.1%, respectively, in sensitivity analyses).
ConclusionsBy age 18, an estimated 1 in 4 children are identified by CSC as needing support at some point. Government should monitor the cumulative incidence of ever receiving CSC support with a view to addressing upstream health and social determinants.
Holography and Dualities in Quantum Field Theories
Authors:   , Stuardo Ricardo
Published: January 2025

The strong coupling regime of Quantum Field theories is studied by using two different frameworks in String Theory. First, by using brane configurations and studying its dynamics, we propose an electric-magnetic duality for three dimensional Yang-Mills Chern-Simons with and without SUSY. By analising the infrared structure we check the validity of this duality. Then, using the Gauge/Gravity correspondance, we study the strong coupling regime of SQFT in different dimensions, which may or not be conformal. We compute some observables and propose that the theories confine.

Investigations were conducted during the rabi (November–April), 2021–22 and 2022–23 at the Bio-control Laboratory, Department of Plant Pathology, SVPUAT, Meerut, Uttar Pradesh, India to assess the effects of micronutrients, botanicals, bioagents and fungitoxicants against Bipolaris sorokiniana causing spot blotch disease in wheat. Using the poison food technique; 7 micronutrients (manganese sulphate, zinc sulphate, ferrous sulphate, boron, sulphur, molybdenum, and calcium chloride), 4 botanicals (extracts of garlic clove, tulsi leaf, neem leaf, and mentha leaf), 4 bioagents (Pseudomonas fluorescens and three strains: SV-7, SV-28, and IRRI-1 of Trichoderma harzianum) and 6 fungitoxicants (azoxystrobin, difenoconazole, propiconazole, tebuconazole, azoxystrobin+tebuconazole, carbendazim+mancozeb) were assessed. The inoculation plates were incubated at 25±1 0C until the fungus covered the control plate completely. After incubation, the colony’s radial growth was measured at regular intervals for one week at 3, 4, and 7 days. The percentage inhibition of each treatment was then computed after the seventh day of incubation. The study revealed that the mycelial growth of Bipolaris sorokiniana was significantly inhibited by the following: botanicals (garlic clove and neem leaf extracts), bioagents (Trichoderma harzianum: Strain- IRRI-1 and SV-7), micronutrients (ferrous sulphate, zinc sulphate, and boron), and fungitoxicants (propiconazole and tebuconazole). Based on the findings mentioned above, and the final recommendation given to the farmers; these potential elements can be assessed for the effectiveness of their individual and combined application against spot blotch disease of wheat under field conditions.

The present experiment was conducted during January, 2022 to December, 2023 in Mulugu,  Warangal and Hanmakonda districts of Telangana state, India to study on the generation of self-employment, provide supplementary income, and ensure access to protein food at a low cost. Backyard Poultry (BYP) was introduced by Krishi Vigyan Kendra Mamnoor as a livelihood initiative to improve the socio-economic conditions of Scheduled Caste and Scheduled Tribe communities. In 2022 and 2023, over 9,870 vaccinated Rajasri birds were distributed to 987 beneficiaries across the 11 villages under the Scheduled Caste and Tribal Sub Plan programs. Each farmer received a unit of 10 Rajasri birds, valued at ` 1000, along with supplementary medicines and vaccines. The study found that Rajasri birds attained sexual maturity at 165 days, with an average body weight of 1200–1300 g under scavenging conditions. They produced an average of 1200–1300 eggs per unit over 52 weeks, with each egg weighing 45–50 g. This generated a net average annual income of `Rs. 7,930.27 from the sale of eggs and male birds through Backyard Poultry. There was also a notable increase in egg and meat consumption among SC/ST families. On average, each unit of Backyard Poultry produced 933 eggs annually. The per capita egg consumption in the villages increased effectively along with supplementary income, chicken meat, and eggs as well as poultry manure for enhancing soil fertility.

Published: January 2025

The study was conducted at the Division of Veterinary Anatomy from 2021–2022 to understand the functional aspect of reticular groove and scarcity of literature in sheep. Reticular groove was characterized by floor and two muscular lips extending from the cardia to the level of reticulo-omasal opening. Both the lips were prominent and more developed in the aboral part than in the oral part. The left lip was cranial whereas the right lip was more caudal in position. The width was maximum in middle. Papillae resembling the claws of a small bird.were seen towards reticulo-omasal opening. Histologically, reticular groove was lined by stratified squamous keratinized epithelium. Incomplete lamina muscularis mucosae was seen mainly in the lips. Lamina propria blended with tunica submucosa. In the floor of groove, mainly transverse smooth muscle fibers were seen whereas lips contained thick longitudinal smooth muscle fibers. The epithelium and keratin layer were thicker at lips. Lamina propria submucosa was thicker at floor. Histochemically, strong positive PAS reaction was seen in the stratum corneum whereas basement membrane showed moderate PAS reaction. Cells of stratum granulosum showed strong reaction for Alcian Blue (pH 2.5) whereas other layers showed moderate reaction for Acid mucopolysaccharides with Alcian Blue (pH 2.5). Glycogen was moderately observed in the lamina epithelialis except stratum corneum. Layers of lamina epithelialis and tunica muscularis showed strong reaction for basic proteins. Stratum corneum showed strong reaction for lipids whereas other layers were weak to moderately positive.

A study was conducted during October, 2022 to June, 2023 at National Dairy Research Institute, Karnal, Haryana, India to evaluate the thermal performance and melting behaviour and the effect of different container materials on energy storage efficiency of phase change materials (PCMs). Paraffin wax, Beeswax and Palm oil was selected for this study and for the container material stainless steel (SS) and polyethylene terephthalate (PET) was selected.  The results indicated that PET containers, although slower to heat (100 min), provide a prolonged cooling period (240 min), making them ideal for applications that require delayed heat release. Among the PCMs, Paraffin wax, with a melting temperature of 59.3°C and a melting time of 36 min, was found to be the most suitable for solar thermal applications. Beeswax, while viable, had a higher melting temperature (68.1°C) and a longer melting time (48 min). Palm oil, with a melting temperature of 43°C, was deemed unsuitable. Image analysis confirmed these findings, showing that palm oil had the highest reduction rate in area and perimeter, while all three PCMs displayed favourable roundness values. Based on the results, Paraffin wax in PET containers was identified as the optimal combination for efficient solar energy storage.

The investigation was conducted during the year 2019–2021 at College of Horticulture, UHS, Bagalkot in acid lime [Citrus aurantifolia (Christm.) Swingle] cv. Kagzi lime to ascertain influence of strength of tissue and propagation conditions on ability of rooting. The treatments included three types of cuttings (shoot tip, semi-hardwood and hardwood cuttings) and three propagation conditions (shade net, poly house and mist house). Coco peat filled portrays was used as the standard rooting media and container. The experiment was laid out in two factorial completely randomised design (FCRD) with three replications. There was significant influence of both strength of tissue and propagation conditions on shoot and root parameters. Combination of these two factors too had significant influence. Further, among the interactions, hardwood cutting+shade net had given maximum sprouting percentage (66.66%), number of sprouts at 30 DAP (3.67), length of shoots at 30 DAP (3.42 cm), fresh weight and dry weight (7.40 and 4.52 g), length of longest root (11.38 cm) and rooting percentage (64.81%). The interaction of hardwood cutting+mist house had produced maximum length of shoot at 60 and 90 DAP (5.46 and 9.15 cm), whereas, the minimum number of days taken for sprouting was recorded in the interaction of shoot-tip cuttings+shade net with 22.95 days. It also implied that the hardwood cuttings in combination with shade net were better to induce more shooting and rooting parameters under hot and dry weather conditions.

A field experiment was carried out during the year summer seasons (February to May) of 2019–2021 in at Horticulture Instructional Farm, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar Gujarat (385 506), India to study the effect of GA3 on growth, sex expression and yield of watermelon (Citrullus lanatus Thunb.). Plant growth regulators in cucurbits have shown promise in improving crop growth and productivity by affecting several physiological and developmental processes. The experiment was laid out under randomized block design with three replications and eleven treatments namely T1 (GA3 10 ppm), T2 (GA3 20 ppm), T3 (GA3 30 ppm), T4 (GA3 40 ppm), T5 (GA3 50 ppm), T6 (GA3 60 ppm), T7 (GA3 70 ppm), T8 (GA3 80 ppm), T9 (GA3 90 ppm), T10 (GA3 100 ppm) and T11 (Control). The variety sugar baby is tested under the experiment. The results revealed that length of the main vine (219.91 cm), number of days to first male flower (50.98), sex ratio (8.01), number of fruit vine-1 (2.99), fruit yield vine-1 (5.04 kg) and fruit yield ha-1 (33.25 tone) were highest in treatment T8 (GA3 @ 80 ppm). Thus, foliar application of GA3 80 ppm twice at 2–4 leaf stages and at flowering stage found effective in enhancing the growth, sex expression and yield attributes of watermelon. These findings provide valuable insights into optimizing agricultural practices through the integration of PGRs, improving productivity and profitability, and supporting sustainable watermelon cultivation.

Published: January 2025

Agroforestry is a transformative land-use strategy that integrates trees, crops, and livestock into cohesive systems, promoting sustainability through enhanced environmental, economic, and social outcomes. By blending diverse plant and animal species, agroforestry systems foster ecological balance and resilience, supporting biodiversity, soil health, and water conservation. Proper management of these resources, particularly soil, water, and biodiversity, is crucial for maximizing both ecological and economic benefits. Effective soil management enhances nutrient cycling and improves soil structure, ensuring long-term productivity. Integrated Nutrient Management (INM) combines organic and inorganic fertilizers to boost soil fertility and plant health, promoting growth while maintaining environmental integrity. The success of INM relies on factors such as soil characteristics, climate, and plant species, all influencing its effectiveness in agroforestry systems. These variables impact nutrient dynamics, necessitating adaptive management practices. Moreover, socio-economic factors such as land tenure, farmer knowledge, and market access influence the adoption and success of INM practices. Therefore, understanding the local context and incorporating these elements into agroforestry planning is essential for maximizing its benefits. The integration of efficient resource management with INM in agroforestry systems is vital for achieving long-term sustainability, ensuring food security, and promoting environmental conservation. Agroforestry optimizes nutrient use and promotes plant synergy, offering sustainable solutions to global challenges like climate change and food security.

Published: January 2025

The experiment was conducted in 2022 (July to December) at J.N.K.V.V., Jabalpur, Madhya Pradesh, India to explore the efficacy of new combo agrochemicals against soil borne phytopathogenic fungi,i.e. Rhizoctonia solani and Macrophomina phaseolina. The pathogens were isolated from infected soybean plants and identified based on cultural and morphological characteristics. Five combo fungicides/ agrochemicals were tested based on their active ingredients at 50 and 100 ppm in four replications. The mycelial development of R. solani was significantly inhibited by penflufen 13.28%+trifloxystrobin 13.28% FS (100%) and thiophanate methyl 45%+pyraclostrobin 5% FS (100%), carboxin 37.5%+thiram 37.5% DS (88.33%) and carbendazim 12%+mancozeb 63% WP (80.55%) at 100 ppm. Whereas mycelial development of M. phaseolina was entirely inhibited by penflufen13.28%+trifloxystrobin 13.28% FS, thiophanate methyl 45%+pyraclostrobin 5% FS and carboxin 37.5%+thiram 37.5% DS at 100 ppm. Penflufen 13.28%+trifloxystrobin 13.28% FS completely checked both pathogen’s mycelial development even at 50 ppm. The significant lowest growth inhibition of R. solani (45.83%) and M. phaseolina (50.27%) was recorded by azoxystrobin 2.5%+thiophanate methyl 11.25%+thiamethoxam 25% FS at 50 ppm. Efficient combo fungicides in the present investigation could be tested against other fungal pathogens and applied as a seed treatment to reduce the fungal infection in the early stages of crops.

Mulher negra, filha de pai branco e mãe negra, a musicista popularmente conhecida como Chiquinha Gonzaga foi incontestavelmente abre alas com sua postura na vida. A difícil encruzilhada raça e gênero não a impediu de confrontar as regras da sociedade de seu tempo. Como operária da música, Chiquinha Gonzaga se sustentou e destinou parte da receita obtida da venda de partituras de suas composições, realizadas de porta em porta, à compra de alforrias de seus irmãos negros. A história dessa mulher negra e suas contribuições para a recepção de ritmos afro-brasileiros para além das classes populares, sua presença na luta abolicionista e sua ação na organização coletiva dos operários da música e do teatro de revista, é o que nos propomos a negritar.
Clóvis Moura e Cedric Robinson: diálogos sobre a Tradição Radical Negra
Authors: Nogueira Fábio
Published: January 2025

Este artigo tem como objetivo estabelecer um diálogo entre o pensamento de Clóvis Moura, em sua obra O negro: de bom escravo a mau cidadão?, de 1977, e o conceito de “tradição radical negra” do afro-norte-americano Cedric Robinson, presente em seu livro Marxismo negro: a invenção da tradição radical negra, de 1983. O presente artigo busca identificar as convergências e divergências entre as ideias de Moura e Robinson, destacando a importância da luta e resistência dos negros na formação de uma tradição radical própria e sua relevância para uma ciência social que supere a sua tendência de “racionalização” das desigualdades raciais.
Clóvis Moura como intérprete marxista da América Latina: notas aproximativas
Authors: Oliveira Patrick
Published: January 2025

Este artigo é uma primeira aproximação ao estudo da obra moureana em relação à América Latina. O objetivo maior da pesquisa é localizar as contribuições (tendências e possibilidades) e os limites de Clóvis Moura diante do que entendemos por história do pensamento marxista sobre a escravidão, que abrange autores como Caio Prado Jr., Jacob Gorender, Florestan Fernandes, Eric Williams, Dale Tomich, Angela Davis, Walter Rodney, C.L.R. James, Robin Blackburn etc. O estudo da América Latina pelo autor é um capítulo dessa agenda marxista. A metodologia do trabalho é revisar escritos de Moura sobre o continente, pelo prisma de três categorias importantes: mercado mundial, desenvolvimento desigual e práxis. A conclusão do texto é que o autor interpreta a América Latina a partir de uma relação dialética entre a luta política dos “de baixo” e o desenvolvimento capitalista dependente.
Sociologia, Antropologia e raça em Clóvis Moura
Authors: Monteiro João Pedro
Published: January 2025

Neste artigo busca-se compreender o procedimento metodológico e analítico envolvido na crítica da noção de raça na obra de Clóvis Moura. Para isso, delineia-se o modo como o autor compreende a formação histórica da Sociologia através de seu traumatismo de nascimento, isto é, sua particularidade histórica, as revoluções burguesas e como sua lógica influenciou na formação da antropologia. A antropologia se distingue da sociologia pelo seu traumatismo de nascimento, o colonialismo, que necessitou da construção do conceito de raça, de raiz metafísica e não sociológica, para produzir sua fundamentação imobilista. Assim, ao produzir a crítica do modo como este conceito se forma e atua no interior da Antropologia, é possível compreender o seu conteúdo de verdade, a dinâmica social efervescente que se esconde debaixo da conceituação imobilizadora.

A quilombagem e a práxis negra: a relação entre as categorias de Clóvis Moura e a revolta da balaiada (1838-1841)
Authors: Peres Ilson de Souza
Published: January 2025

O presente trabalho aborda a escravização negra no Brasil durante o período que pode ser denominado como a era das revoltas no Brasil, para ser mais especifico, o regencial, compreendido entre 1831 a 1840. Neste sentido, objetiva-se neste trabalho, analisar a relação entre as categorias mouriana práxis negra e quilombagem e a Revolta da Balaiada, ocorrida na província do Maranhão, em 1938-1841, considerada a maior revolta oitocentista. Aborda-se o tema a partir de uma perspectiva que critica a historiografia oficial que objetificou os/as negros/as e de igual modo, também critica o método histórico cultural que interpretou a escravidão como um componente suplementar à realidade, e assim mistificou-se a resistência negra ao escravismo, bem como sua contribuição para o desgaste desse sistema, social e economicamente.
Breve ensaio sobre grupos específicos negros, consciência e luta de classes no Brasil
Authors: Silva Sandra Regina Vaz da
Published: January 2025

“Grupos específicos e diferenciados” é uma categoria de análise utilizada por Clóvis Moura para tratar dos grupos específicos negros no Brasil, a partir da concepção marxiana de classe em si e classe para si. Este ensaio procura apresentar a análise do autor, consoante ao protagonismo das lutas negras na particularidade da formação social brasileira, suas incidências e importância no processo de consciência antirracista e anticapitalista. O texto se fundamenta em estudos bibliográficos, documentos, debates e reflexões em grupo de estudos. Está estruturado em dois momentos, sendo o primeiro a análise da categoria grupos específicos e diferenciados e o segundo, uma articulação do debate sobre racismo e capitalismo no Brasil, que elucida a necessária vinculação entre anticapitalismo e antirracismo como tarefa histórica da classe trabalhadora brasileira.
Clóvis Moura: política cultural e programa de estudos (1950-1955)
Authors: Rocha Gabriel dos Santos
Published: January 2025

Neste artigo trataremos das atividades de Clóvis Moura no âmbito da política cultural do então Partido Comunista do Brasil (PCB) em São Paulo nos anos 1950. Para tanto, abordaremos a inserção do autor em Fundamentos: revista de cultura moderna (1948-1955), periódico do partido dedicado a temas artísticos, científicos, políticos e econômicos. A participação de Moura nos revela sua sociabilidade intelectual e militante – sobretudo através da produção literária – no período que antecede a publicação de Rebeliões da Senzala (1959), sua relação com as diretrizes culturais pecebistas, e traz algumas pistas de seu programa de estudos de História e Sociologia Intelectual que resultaria em seu segundo livro no campo das ciências humanas, Introdução ao pensamento de Euclides da Cunha (1964).

Published: January 2025

Desenvolvido por meio da pesquisa qualitativa, com a entrevista via telefone como ferramenta de produção de dados, e dialogando com referenciais de perspectiva crítica sobre o trabalho, este artigo se voltou para a seguinte pergunta: a pandemia decorrente do COVID-19 está contribuindo para que as pessoas que trabalham em serviços de entrega de alimentos por aplicativo, em Natal-RN e região metropolitana, se insiram mais fortemente no precariado? Os dados produzidos apontam para um cenário em que o caráter precário do trabalho dessas pessoas é agudizado pela pandemia.

Lima Barreto e as dinâmicas raciais no romance 'Clara dos Anjos'
Authors: Carvalho Samara dos Santos
Published: January 2025

Lima Barreto foi o mais proeminente, entre os autores brasileiros do século XX, a manifestar o ponto de vista dos negros sobre o preconceito racial. Em 1922, meses antes de seu falecimento publica seu último romance, Clara dos Anjos, que narra uma história de sedução e abandono vivenciada pela personagem-título, uma jovem mestiça de origem humilde. No romance, o autor esmiúça a complexidade das dinâmicas sócio-históricas ambientadas pelas camadas populares no período da Primeira República.

Autogestão e controle operário: semântica e política na experiência argentina
Authors: Pinheiro Jair , Nemirovsky Gabriel Gualhanone
Published: January 2025

O presente artigo tem a intenção de colocar em tela o problema relativo ao efeito negativo que a separação político-semântica entre os termos “autogestão” e “controle operário”, promovida pela prática concreta das Empresas recuperadas por Seus Trabalhadores (ERTs) argentinas, exerce tanto sobre a forma como estas se relacionam com o Estado burguês quanto sobre como essa relação passa a ser interpretada academicamente. Para tanto, lança-se mão da contribuição do pensador marxista Nicos Poulantzas para articular as noções de Estado, seus aparelhos e a reprodução das relações sociais de produção sob o modo social de produção capitalista. Em conclusão, considera-se que as demandas sociais levantadas pelos trabalhadores de ERTs tendem a não avançarem se não se inserirem numa reflexão sobre a concepção de Estado burguês, dos fundamentos de seu ordenamento jurídico e das alternativas estruturalmente viáveis.
Junho de 2013: um balanço dez anos depois
Authors: Firmino Gustavo Casasanta
Published: January 2025

O artigo estabelece alguns paralelos entre as manifestações de junho de 2013 e aquelas que ocorreram durante o biênio 2015-2016, nas quais exigia-se o impeachment da então presidente da República, Dilma Rousseff (PT). Três eixos de análise organizam o texto: 1) a discussão sobre o perfil socioeconômico do público presente em ambos os blocos de manifestações; 2) as principais bandeiras e reivindicações apresentadas em cada ocasião; 3) o perfil político-ideológico dos movimentos convocantes e/ou dirigentes dos protestos. Cada um desses eixos converge para uma discussão de fundo concernente ao papel desempenhado por segmentos das classes médias nas conjunturas em tela. Cientes da impossibilidade de esgotar todas as questões suscitadas, buscamos argumentar, com base em pesquisa empírica, que os protestos de junho viriam a inaugurar um novo ciclo político no Brasil, marcado pela ofensiva liberal-conservadora aos governos do PT.
Da ruptura metabólica à regeneração: a produção de mudas nativas como ferramenta de transformação
Authors: Pagotto Claudete
Published: January 2025

Este artigo analisa a relação entre o processo de produção de mudas nativas no viveiro florestal e o programa de educação ambiental da Associação Ambientalista Copaíba (AACopaíba), em Socorro-SP. Por meio de uma abordagem qualitativa, que inclui a observação participante, são discutidas as práticas de restauração ecológica na Mata Atlântica, fundamentadas na ecologia marxista e na noção de ruptura metabólica. A análise enfatiza a lógica predatória do capitalismo e seus impactos ambientais, e a educação ambiental crítica como uma estratégia para superar as crises ambientais contemporâneas.
