Study on the Significance of Reduction to the Equator (RTE), Reduction to the Pole (RTP), and Pseudogravity in Magnetic Data Interpretation
Authors: Rusman Mira Nailufar , Alawiyah Susanti , Gunawan Indra
Published: August 2023

Interpretation of geomagnetic anomaly data is challenging, due to the influence of the Earth's dipole magnetic field. In this study, we investigate the significance of employing methods to transform dipole anomalies into monopoles, aiming to enhance the interpretability of the data. Four methods were examined: Reduce to Pole (RTP), Reduce to Equator (RTE), and Pseudo-Gravity. The RTP method was implemented using general equations for RTP, Pseudo-inclination (PI), and Nonlinear thresholding (NTRTP). The computation programs for RTP and RTE were developed using the Matlab programming language. Synthetic models were constructed to investigate the effects of inclination values, object dimensions, and positions on the resulting magnetic anomaly response. The result shows that NTRTP methods give the best result with coefficient correlation >0.9. It can be used in every condition (low or high inclination). The implementation was conducted utilizing magnetic data in the Gunung Pandan geothermal area. The application of the reduced to the pole (RTP) technique on the field data successfully remove the dipole effects, and make interpretation process easier. Based on RTP map, the range of anomaly values spanning from -800 nT to 1000 nT. High anomalies were observed at the Gunung Pandan site, indicative of a probable intrusion of andesitic igneous rock.
Identification Of Liquefaction-Potential Zones Using The Gravity Method In Lolu Village, Central Sulawesi
Authors: Silalahi Meschac T. , Dahrin Darharta , Abdurrahman Dadi , Tohari Adrin
Published: August 2023

A seismic event of magnitude 7.5 struck the Palu region in Central Sulawesi on September 28, 2018, precipitating a subsequent calamity in the form of a tsunami measuring 4-7 meters in height. This catastrophe was further compounded by the occurrence of liquefaction, leading to extensive devastation and a significant loss of life. In order to identify areas susceptible to liquefaction, it is anticipated that the employment of the gravity method, renowned for its capacity to discern density fluctuations associated with the mass of voluminous materials over a considerable detection range, will prove instrumental. The investigation of parameters and the characterization of liquefaction phenomena in regions previously afflicted by liquefaction disasters can be instrumental in devising strategies for mapping zones that are predisposed to such occurrences. The present study seeks to employ geophysical methods, specifically the gravity method, to delineate zones with the potential for liquefaction within the Lolu Village at Palu City, Central Sulawesi. Through the application of techniques designed to isolate regional and residual anomalies, it is envisaged that a clearer understanding of anomalies situated in shallower regions can be attained, with a specific focus on residential areas. Notably, due to liquefaction, approximately half of the residential areas have shifted a considerable distance of around 132 meters from their original positions. To facilitate the interpretation of subsurface layers, two-dimensional cross-sections are modeled to intersect the displaced and stationary areas. The residual map reveals discernible variations in anomaly values, with lower values observed in the areas that experienced liquefaction-induced movement. Subsurface modeling further demonstrates the presence of three distinct rock layers, namely a sandy layer, a gravel layer, and a rock layer. Additionally, the modeling depicts the formation of canals composed of hard rock, exhibiting varying thicknesses within the surface layer as a consequence of the liquefaction event in 2018. The existence of these canals serves as an indicator that when the sandy layer becomes saturated with water, it will flow along the topographical gradient, following the path of the subterranean canals that have formed.

Authors: Artika Wiwit , Rosemary Rizanna
Published: August 2023

The environmental STEM (E-STEM) approach helps students to understand problems related to the environment and solutions to overcome the issues. Many studies show how applying the E-STEM approach in education increase students' awareness of protecting the environment and being adaptive and resilient to the impact of climate change. This paper explains the findings of E-STEM learning activities and outcomes in a school setting (grade XI) in Aceh. Qualitative approach with Focus Group Discussion (FGD) with 11 senior high school students taught about the environmental issue using the E-STEM. Students have low environmental awareness of the impact of climate change. Furthermore, students' unwise behavior in using electricity and transportation and lack of waste management indicate a gap in implementing the E-STEM approach within the current National Independent Learning Curriculum. Despite the shortcoming of the learning activities and outcomes, the study highlights the importance of introducing natural connectedness through E-STEM learning at an early age to be adaptive and resilient to the impact of climate change
Prospective Coronavirus Liver Effects: Available Knowledge
Authors: Avishek Mandal
Published: August 2023

The global pandemic COVID-19, caused by SARS-CoV-2, affected millions of people. COVID-19 is known for its respiratory symptoms, but new research reveals it may also affect other organ systems, including the liver. This abstract reviews COVID-19 and liver function. The virus enters host cells through liver-expressed angiotensin-converting enzyme 2 (ACE2) receptors. Thus, viral infection and replication may target the liver. Virus-induced inflammation and cytokine production may also harm the liver. ALT and AST elevations are the most prevalent liver abnormalities in COVID-19 patients. Liver function test abnormalities frequently indicate serious illness and poor clinical outcomes. COVID-19 may worsen pre-existing liver diseases such as NAFLD and chronic viral hepatitis. Drug-induced liver damage (DILI) from COVID-19 therapies including antivirals and corticosteroids complicates liver complications care. Recent investigations have also shown that COVID-19 may cause long-term liver damage. In conclusion, COVID-19 infection, immune-mediated damage, and treatment problems may severely compromise liver function. Optimizing patient treatment and discovering targeted medicines requires understanding COVID-19's liver role. To reduce the effects of COVID-19 on liver function, further study is required to understand the mechanisms and long-term effects.
Synergistic Approach: Photobiomodulation, Neuromodulation, and Drug Therapy in Neuropsychiatry. A Promising Strategy to Enhance PBM Adoption and Neurotherapy Efficacy
Authors: Farzan Vahedifard
Published: August 2023

Photobiomodulation (PBM) is an effective method for treating neuropsychiatric diseases, yet its universal acceptance and utilization remain constrained. In this Letter to the Editor/Expert Opinion, we address the challenges confronting PBM researchers and pioneers, striving to establish universal confidence in its exclusive application for neuropsychiatric patient care. Despite encouraging animal experiments and selecting positive human clinical trial outcomes, PBM’s widespread acceptance of PBM is hindered by factors including limited clinical studies and clashes with established therapies, such as drug therapy and psychotherapy. To overcome these obstacles and broaden PBM’s adoption and application of PBM in neuropsychiatry, we propose a combinatorial therapy approach. By integrating PBM with interventions such as Cognitive Behavioral Therapy (CBT) or drug therapy, a cumulative effect can be attained, benefiting both patients and therapists. Patients gain access to diverse treatment options and experience synergistic effects of combined therapies, thereby enhancing outcomes. Therapists benefit from expanded intervention choices and improved quality of patient care. This study introduces a novel strategy of amalgamating PBM with recognized interventions, such as CBT and drug therapy, to address existing challenges. This combined approach offers a practical solution to augment PBM acceptance and usage in the realm of neuropsychiatry. To endorse this strategy, a shift in the research direction is imperative. Future studies should investigate the amalgamated use of PBM with other neurointerventions, such as CBT or drug therapy. Robust clinical trials contrasting groups like “PBM + CBT” and “PBM (sham) + rTMS” are vital to persuade clinicians and patients toward embracing combined PBM therapies. Although PBM’s eventual autonomy as a neuropsychiatric treatment is an overarching goal, the present combination therapy approach proves practical, inevitable, and mutually beneficial. By bridging conventional therapies with PBM, this strategy may facilitate wider acceptance and utilization in neuropsychiatry.

Authors: Dyvnych Hanna
Published: August 2023

The purpose of the paper is to study the institutional strategies of higher education institutions for the development of social entrepreneurship and the existing formal structures aimed at supporting this activity, as well as to outline the directions of university activities implemented according to the strategies. Methodology. The research is based on the collection and analysis of data from the official websites of 10 universities from different countries of Europe and America, which either clearly state efforts to develop social entrepreneurship, or have entrepreneurship development together with a focus on the third mission of the university. The empirical data are combined with the outlines of modern scientific research of Ukrainian and foreign scientists on the topics of social entrepreneurship and the third mission of universities. The results of the study show that universities around the world are paying more and more attention to the importance of their third mission and see themselves at the heart of community development in all its diversity of needs and activities. At the same time, very few define the development of social entrepreneurship as one of their objectives, and most work on entrepreneurship development in general, pointing to the importance of directing university education and research towards tackling social challenges. Practical implications. As many universities already have administrative support and a range of activities for the development of entrepreneurship education and youth start-ups, together with a focus on the third mission of universities, a favourable environment is being created to introduce the development of social entrepreneurship as one of the strategic goals of modern higher education institutions under the conditions of modern global issues. Value/оriginality. The study was carried out as part of a young researchers' project on the development of social entrepreneurship centres at Ukrainian universities for the post-war development of the country.

Published: August 2023

Background: The choice of reperfusion therapy in STEMI patients with COVID-19 is unclear. CRP to Albumin ratio (CAR) found to be a predictor of thrombus burden. This study was to determine the relationship and predictive value of CAR to in-hospital and long-term outcome of STEMI patients with COVID-19 treated with fibrinolytic.
Methods: 297 COVID-19 patients with STEMI underwent fibrinolytic were enrolled. In-hospital outcomes were in-hospital mortality due to cardiovascular death which was divided into mortality <48 hours and >48 hours, fibrinolytic failure, and cardiogenic shock. The presence of reinfarction post fibrinolytic and mortality after the patient discharged was assessed as the long-term outcome.
Results: During follow-up, 19.8% experienced in-hospital mortality and 16.1% had reinfarction. In the in-hospital outcome, patients with in-hospital death, failed fibrinolytic and cardiogenic shock had higher CAR (6.7+2.4 vs 4.7+1.9; 6.3+1.9 vs 2.1+1.6; 5.5+2.1vs1.8+1.5) with all p-value <0.05. CAR with an optimal cut-off >4.46 can be a predictor of fibrinolytic failure with sensitivity of 86.7% and specificity of 93.6% (PR19.82; 95%CI 10.32-38.06) and predictor of in-hospital death <48 hours with sensitivity of 84.6% and specificity of 82.7% (PR5.02; 95%CI 3.20-7.90). In the long-term outcome, patients who experienced reinfarction and out-hospital death had higher CAR (5.1+1.2vs2.5+2.4; 5.2+1.3vs2.6+2.4) than those who did not experience the event respectively with all p-value <0.05. CAR with an optimal cut-off >3.67 can be predictor of reinfarction with sensitivity of 87.5% and specificity of 73.5% (PR12.250; 95%CI 5.38-27.87). The Cox regression model showing CAR >3.67 was also associated with higher reinfarction event (p=0.001).
Conclusion: CAR has the potential to be a predictor of in-hospital and long-term outcomes for STEMI patients with COVID-19 which can help determine which patients need more invasive strategy to prevent mortality and morbidity.

Authors: Asrial An Aldia , Pudjiastuti Anggit
Published: August 2023

Background

Zwolle, TIMI, and GRACE risk scores have been proven to predict mayor adverse cardiovascular events (MACE) in STEMI patients undergoing primary percutaneous coronary intervention (PCI). However, they were developed over a long time ago which many advances have been made in the cardiovascular field today. The scores were also developed in the non-Asian majority population and their accuracy for Indonesian population remains unknown. We aimed to validate and compare these scores for Indonesian population.

Methods

An analytical observational study was conducted on 193 patients undergoing primary PCI. The Zwolle, GRACE, and TIMI risk scores were calculated for each patient. Then, the risk score validation was carried out with the calibration test using Hosmer Lemeshow test and discrimination test using the AUC ROC. Furthermore, the comparisons between the risk scores were carried out using the DeLong test.

Results

The three scores have good results in the Hosmer Lemeshow calibration test (p > 0.05). The discrimination test also indicated good results with AUC ROC Zwolle, TIMI and GRACE risk scores respectively 0.776; 0.782; 0.831 (p<0.05). There was no significant difference in the prediction accuracy of the three risk scores in the DeLong test.

 

 

Conclusions

The Zwolle, TIMI, and GRACE risk scores had good validity for predicting major adverse cardiovascular events in STEMI patients undergoing primary PCI. There was no significant difference in the prediction accuracy of the three risk scores.

The Importance of Hyperthyroid Screening in Acute Decompensated Heart Failure with Persistent Tachycardia Despite Optimal Decongestion: A Case Report
Authors: Wijayanto Matthew Aldo , Myrtha Risalina , Prabowo Nurhasan Agung
Published: August 2023

Background: Hyperthyroid has various effects on the cardiovascular system. Cardiac arrhythmias ranging from sinus tachycardia to atrial fibrillation and low/high cardiac output state to congestive heart failure are observed in patients with hyperthyroidism. If hyperthyroidism is recognized and treated early, the cardiac dysfunction could be corrected. This case presentation will discuss the importance of thyroid function screening.

Case Illustration and Discussion: A man was admitted to the emergency department with signs and symptoms of acute decompensated heart failure. Further examination was performed to confirm the diagnosis, namely ECG, laboratory examination including thyroid function test, and echocardiography. During hospitalization, heart failure medication was given and up titrated. The patient was still tachycardia until hyperthyroid was corrected with anti-thyroid medicines.

Conclusion: Hyperthyroidism can cause or worsen left ventricular dysfunction, especially in individuals with a history of cardiovascular disease. Thus, thyroid function tests should be assessed during initial laboratory examination, especially on patients with acute decompensated heart failure.
Management of Decongestion in Acute Heart Failure: Time for a New Approach?
Authors: Pramudyo Miftah
Published: August 2023

As the primary cause of hospitalization in acute heart failure (AHF) patients, congestion was responsible for a higher risk of mortality, rehospitalization, and renal dysfunction in AHF patients. Although loop diuretic was routinely used as the mainstay of AHF therapy, it is still ineffective to obtain the euvolemic state in most hospitalized AHF patients. Therefore, a higher loop diuretic dose was often required to increase the decongestion effect. However, consequently, it can cause several detrimental complications, including renal dysfunction, neurohormonal activation, hyponatremia, hypokalaemia, and reduced blood pressure, which eventually result in poor prognosis. Hence, the new approach may be proposed to optimize decongestion in acute phase, including the use of arginine vasopressin V2 receptor antagonist – Tolvaptan. As an additive therapy to loop diuretic in AHF patients, it can be considered due to its several beneficial effects, including greater decongestion effect, lowered worsening renal function incidence, counteract neurohormonal activation, neutralized hyponatraemic state, no alteration of potassium metabolism, stabilize the blood pressure, and reduced requirement of a higher dose of loop diuretic to achieve an equal or even greater decongestion effect compared to a high dose of loop diuretic alone. Tolvaptan provided favourable outcomes in several specific populations and was considered safe with several mild adverse effects. Several guidelines across countries have approved the use of Tolvaptan in AHF patients with or without hyponatremia. The initial dose of Tolvaptan was 7.5 to 15 mg and can be titrated up to 30 mg. However, further studies were still required to determine the timing dose and optimal dose of Tolvaptan in general and elderly populations with AHF, respectively.
Identification of seropositive wild boars in Eurasia as a sign of possible formation of African swine fever-endemic areas (review)
Authors: Bespalova T. Yu. , Glazunova A. A.
Published: August 2023

The continued spread of African swine fever (ASF) in Eurasia remains a global problem for the world pig industry. The disease is characterized by high mortality (up to 100 %) and acute course - domestic and wild animals die within the first two weeks after infection. However, active surveillance on ASF in Eastern Europe had been showing regular detection of seropositive susceptible animals, especially among wild boar populations which may indicate chronic, asymptomatic infection and even the survival of individual animals. At the same time, the persistence of the virus in the wild boar population creates constant risks of sporadic outbreaks of ASF in infected areas, and the infection can become endemic.

   The aim of the study was a systematic review of the available data on seroprevalence among wild boars in relation to the possible establishment of ASF endemicity in Eurasia.

   In these animals, there was a change in the dynamics of the disease, which is manifested by self-sustaining cycles of infection. Seropositive wild boars are being found in the Baltic countries, Hungary, Poland, Romania, Slovakia, and Russia. Seroprevalence rates among wild boars hunted in ASF-infected areas of European countries range from 0.3 to 3.8 %. In the Baltic countries, the number of seropositive samples from wild boars exceeds the number of samples positive for ASF virus in polymer chain reaction (PCR). A similar trend persists in those regions where the ASF virus has been present for a long time (Poland, Lithuania, Latvia, Estonia), which may indicate the endemic nature of ASF. In the Russian Federation, ASF-endemic territories in the wild have not yet been registered, although isolated cases of seropositive wild boars have been detected in some regions since 2013. In the future, in order to understand the dynamics of the disease in the wild, it is necessary to conduct a comprehensive diagnosis of the ASF virus genome and antibodies in wild boar samples, which eventually will allow choosing the right strategy to combat ASF.

Published: August 2023

The purpose of the research is a comprehensive assessment of the main breeding valuable traits and properties of a new fiber flax variety Strizh on the basis of breeding variety testing.

   The studies were carried out on sod-weakly podzolic well-cultivated soil in the conditions of the North-West of Russia (Pskov region) in 2018-2020. The most favorable hydrothermal conditions of the growing season for the growth and development of fiber flax were in 2019 (HTC = 1.53; Ij = +1.57), unfavorable – in 2018 (HTC = 0.95; Ij = -0.80). The Strizh variety is a high-yielding in flax fiber early-ripening type (the growing season is 69 days) matures 2-3 days earlier than Dobrynya standard variety. The average yield of flax fiber over the years of the research is 18.6 c/ha, which significantly exceeds the standard variety by 2.3 c/ha or 14.1 % (LSD05 - 0.90 c/ha), maximum yield is 20.3 c/ha. In terms of seed yield, it was inferior to the standard (9.9 c/ha) by 1.8 c/ha or 18.2 %. The new variety is highly resistant to lodging (5 points) and fusarium wilt (85 %). It has a very high flax fiber content in the stems (40.0...40.6 %), which is 3.1...4.8 % (abs.) higher than the standard, and its better quality (strength and flexibility). In production conditions, it provided the production of 19.5 c/ha of flax fiber, that is 2.3 c/ha or 13.4 % higher than the standard (LSD05 = 0.96 c/ha). It has the highest yield under contrasting conditions (genetic flexibility) – 19.3 c/ha and higher stress resistance (-2.0). The Strizh variety and the standard are characterized by low variability of fiber flax yield (CV = 9.8-9.6 %), they are also distinguished by high plasticity (bi = 1.12-1.17), which indicates a good responsiveness of these varieties to improved environmental conditions. The Strizh variety has been in the state variety testing since 2021.

The article shows the results of a multi-environment trial which was conducted in 2022 to determine the adaptability of corn hybrids and identify genotypes which are better to choose for a short growing season. Ten new early-maturing (FAO 130-150) corn hybrids were studied in 6 plant breeding organisations – ecological sites in 4 soil-climatic zones of Russia such as the Central Black Earth region, North Caucasus, Urals, West Siberia. The corn hybrids were evaluated by plasticity (bi), stability (σd2) and selection indices: the breeding value of the cultivar (Svc), the selection index (Si) and the selection value index of the cultivar (Ssvi). Nalchik (Ij = +1.51), Belgorod (Ij = +0.18) and Voronezh (Ij = +0.04) had favourable environmental conditions, unfavourable environments were in Chelyabinsk (Ij = -1.09), Omsk (Ij = -0.56) and Pyatigorsk (Ij = -0.08). Hybrid 140/26 had the highest grain yield (6.50 t/ha) on average, it exceeded the best standard by 1.15 t/ha. The hybrids 140-28 had the highest mean yield (7.66 t/ha) and 140/24 (7.65 t/ha) under favourable conditions, hybrid 100/28 was the best (5.42 t/ha) in unfavourable environments. Hybrids 100/24 (18.7 %), 140/25 (19.0 %), 100/27 (20.5 %) had the lowest grain moisture at harvest. Hybrids 140/24 (bi = 1.82, σd2 = 0.08), 140/28 (bi = 1.54, σd2 = 0.09), 100/26 (bi = 1.45, σd2 = 0.17) with high ecological plasticity and stability were recommended to grow under intensive growing conditions. It was shown that the application of the technique for evaluating corn hybrids by selection indices makes it possible to identify regionally oriented genotypes. It is better to grow hybrids 100/28 (Svic = 8.44) и 100/27 (Svic = 8.26), which had an optimal balance of environmental stability, grain yield and grain moisture at harvest, in unfavourable conditions with a short growing season.
Estimating splitting capability of modified flax fiber during quality control

The existing problem of cotton import substitution ensures the relevance of modified flax fiber production. Modified flax fiber has potential uses in textile manufacturing when mixed with cotton or similar fibers in order to produce non-woven textile materials, as well as armature for biocomposite materials. As such, it is necessary to alter the existing methods of determining modified flax fiber quality in order to pick new quality metrics corresponding to the changes to fiber's structure during processing. In particular, average thickness and length of the modified flax fiber suffer a degree of reduction during fiber's preparation for spinning, which needs to be measured and taken into account. As the result of the research there was proposed the way to estimate the fractioning quotient of modified flax fiber via sliding bending against rounded edges imitating the effects of actual fiber processing. When working parameters and edge geometry are constant, fiber thickness is reduced by ∆ = Torig - Tres. For fiber with thickness Torig in range of 0.109 to 0.135 micrometers the value of ∆ differes from approximately 0.010 to 0.098 micrometers. It was suggested to estimate the fractioning quotient according to value of D = 100·∆ / Torig. During experimental testing of this method using various quality fiber produced in Tver region and Udmurtia Republic the value of D was varying from 0.10...0.15 % to 7.3...7.7 %. It has been established that the suggested method with the use of standard indicator «fiber thickness» enables to take into account the strength of inter-fiber connections according to the currently accepted theory of their formation. Applying this method makes it possible to differentiate full-scale shipments of modified flax fiber using sliding bending stress performed under identical conditions.

Authors: Kazakevich P. P. , Komlach D. I. , Yurin A. N.
Published: August 2023

This article describes the process of creating a training sample of an artificial neural network (hereinafter – ANN) of a vision system. Training the ANN was carried out on the basis of annotated images of real apples containing a description of various defects in the form of separate polygons using the LabelMe program. On the image of the fruit, the apple itself and its pomological features, such as receptacle, stalk and leaf, were marked, as well as 10 different fruit defects, each of which was given an appropriate name: mesh, pressure, cut, rot, scab, hailstone, etc. The obtained labeled images of fetuses with defects formed a reference training set for the ANN. The performance of the ANN was tested by evaluating the correctness of recognition of fetal images when comparing them with reference images. Training the ANN for each of the defects in apples was stopped when 95 % of the probability of correct assessment of the defect was reached. The ANN trained on the created training sample was used in the vision system of the LSP-4 production line, which sorted apples into three commercial varieties by size and defects from mechanical damage, diseases, and pests. The accuracy of sorting by size was 75.4 %, and by the presence of defects – 73.1 %.

Porang rice is made from porang tubers (Amorphopallus oncophyllus) and waxy cassava and has a high glucomannan content and has a low glycemic index (<55). Porang rice has a slightly brownish white color and has a shape like grains of rice and contains fiber which can help the digestive process in the body. Provision of porang rice against diabetic can improve blood profile. This study aims to determine the effect of giving rice from porang tubers pn the blood profile of diabetic mice. The experiment was arranged in a completely randomized design (CRD) with the treatment of observing blood profiles. The study consisted of 4 treatments with 6 replications. The data obtained was tested for uniformity using the Bartlett test and the additional data was tested with the Tuckey test. Furthermore, the data were anlyzed using variance to obtain an estimator of the varience and determine the effect of the treatment, then the data were analyzed using the BNT test at the 5% level.  The results showed that the effect of giving porang rice on the blood profile of alloxan-induced mice gave values for the number of erythrocytes (7,48 million/mm3), leukocytes (5,55 thousand/mm3), hemoglobin (15,14 g/dL), hematocrit (32,28%).

A vuelo de pájaro. Aves en el registro arqueológico, etnográfico y etnohistórico de Mendoza y San Juan (Centro Oeste argentino)

Si bien, existen menciones en trabajos etnohistóricos, etnográficos y arqueológicos, no se ha ponderado, salvo excepciones, el rol que tuvieron las aves en la vida humana en el Centro Oeste argentino. A partir del relevamiento de información arqueológica, histórica y etnográfica, se evidencia que, en una historia de larga duración, en los diversos contextos sociales y culturales que se desarrollaron en el área, las aves no limitaron su aporte a la subsistencia, sino que participaron dentro de sistemas de representación visual que suponen iconografías y usos derivados de sistemas de creencias, rituales y símbolos de poder. Se propone que la presencia de las aves fue constante y significativa en los contextos arqueológicos y no se limitó solo a la evidencia osteoarqueológica ya que se halla representada en una gran variedad de soportes, además de su mención en relatos etnográficos y documentales. Desde esta perspectiva, se plantea que es un registro que debe insertarse con mayor énfasis en la agenda de investigaciones futuras en la región.
Adopción y justicia en la historia argentina. Córdoba en los años sesenta
Authors: Gentili Agostina
Published: August 2023

En este artículo analizo el papel del poder judicial en una etapa temprana del proceso de legalización de la adopción, los años sesenta, momento en que era una figura jurídica reciente pero llevaba siglos de existencia entre los repertorios de conformación de una familia. A partir de una reconsideración y síntesis de trabajos previos basados en el análisis de expedientes de los juzgados de menores Córdoba, sostengo que en esa etapa temprana de la institucionalización de la adopción, las prácticas formales e informales convivían y se retroalimentaban en los procesos legales. Las realidades de la adopción eran diversas y el poder judicial adoptó una actitud flexible y tolerante ante esa diversidad. Al mismo tiempo, construyó en torno a ellas una narrativa que exaltó aquellos rasgos que más se acercaban a los anhelos normativos en materia de familia, suavizó los que los contradecían y ocultó los que podían develar las ficciones de clase en las que esos anhelos se asentaban.
Entre trámites y esperas: reflexiones sobre trabajo de campo etnográfico en una administración municipal (Córdoba, Argentina)
Authors: Tamagnini María Lucía
Published: August 2023

El siguiente artículo presenta una reflexión en torno al estudio etnográfico de prácticas burocráticas en administraciones estatales. Para ello, recupera parte de una investigación sobre la gestión municipal de la diversión nocturna en la ciudad de Córdoba, desarrollada entre 2011 y 2015. Dicha pesquisa propuso indagar procesos de formación del estado municipal a partir de una etnografía de determinados ejercicios de poder para ordenar la noche. Aquí, se presentan unas situaciones etnográficas que (se) configuraron (en) aquel trabajo para elaborar reflexiones situadas en torno a las modalidades del estar allí, el desafío de etnografiar prácticas de poder y la producción de conocimiento socioantropológico sobre el proceso continuo de formación estatal. Con ello, se busca aportar a las discusiones referidas al hacer etnográfico en relación con instancias de poder, los posicionamientos que como etnógrafas podemos ocupar durante el trabajo de campo y las posibles modalidades de acompañar el cotidiano de una administración municipal en pos de aprehender ejercicios de poder a través de los cuales se (re)producen jerarquías sociales, y el estado extiende su presencia ante las y los sujetas/os.
