From the Aramaic raḥmānāʾ to raḥmānān and al-raḥmān
Authors: Gorea Maria
Published: November 2023

The oldest record of the notion of “mercy”, raḥmān, in Aramaic is known from a bilingual text in which the word is the translation of the Akkadian rēmēnû. The latter is used in Mesopotamian onomastics, hymns and prayers, which delivered the oldest formulae of calls for the mercy of gods, especially in a recurrent expression: “the merciful god, that is good to pray,” translated verbatim in the Aramaic text of the statue of Tell Fekheryeh. Almost a thousand years later, the same wording has been inherited unchanged in Palmyrene Aramaic. Nevertheless, the Palmyrene interest on the divine epithet raḥmān and its revival in Palmyrene epigraphy may be explained by the influence of the new Roman concept of clementia. Meanwhile, this contribution proposes to outline a chronology of the Aramaic inscriptions from Syria and Palestine, in which raḥmānāʾ is either the main substitute for the divine name, or a major divine epithet. As the Akkadian phonetic assimilates the consonant <ḥ> to the laryngeal <ʾ> but preserves the velar <ḫ>, the supposed East Semitic root was rḥm, not rḫm. On the contrary, in the Arabian Peninsula, the earliest attested root is rḫm, as evidenced by South Arabic onomastics or toponymy. A late use of rḥm in South Arabic as a verb or noun is the result of a loan from Aramaic and does not appear until the fifth century AD. The first South Arabian inscriptions naming the monotheistic god raḥmānn are preceded by the Palmyrene inscriptions by almost two centuries and are contemporary with the Jewish-Aramaic inscriptions in the Palestinian synagogues, which call the God Raḥmānāʾ. Late, the Aramaic epithet was transferred to the Arabic al-raḥmān, through South Arabian.
The Impact of Mobile Phones on Change in Employment Status in South Africa
Authors: Grzybowski Lukasz , Patel Zubair Maghmood
Published: November 2023

In this paper we analyse whether having a mobile phone impacts chances of getting employed. We use five waves of panel data from the National Income Dynamic Survey (NIDS), which was conducted in South Africa between years 2008 and 2017. In the estimation we include a vector of observable individual and household characteristics and account for unobserved heterogeneity amongst individuals. The estimation results suggest that mobile phone ownership has a positive impact on the change in employment status from unemployed to employed. On the other hand, ownership of a computer by a household and computer literacy do not increase the likelihood of getting employed. The average probability of becoming employed increases from 54.2 % when no one among unemployed adults has a mobile phone to 57.4 % when all of them have a mobile phone, which is an increase of 5.9 %.

Time to Document
Authors: Vesey Alyxandra
Published: November 2023

In recent years, Björk has defied pop music criticism’s persistent myth of male genius by asserting her authorship as a singer, songwriter, composer, and producer. She expressed these concerns during a 2015 Pitchfork interview with Jessica Hopper by reflecting on the press’s minimization of her production work throughout her career and her desire to reclaim her creative authority as a model for younger female-identified artists. During this portion of the conversation, she mused, “I’ve sometimes thought about releasing a map of all my albums and just making it clear who did what.” Her impulse to challenge masculinist creation myths through documentation became the catalyst for Björk: Sonic Symbolism, a 2022 podcast miniseries sponsored by Mailchimp in which she discussed her albums’ creative processes with friends Oddný Eir and Ásmundur Jónson in a series of interviews. The title, which Björk defines as “a visual shortcut to describe sound,” provides the podcast’s framework for her articulation of authorial control, which she examines through album art that illustrates each cover’s mood and character; poetic synopses of each album’s unique audiovisual language; and references to her various studio, video, and stage collaborators. By using close listening to examine Björk’s conversations with Eir and Jónson and the episodes’ illustrative song segments, this article posits that Björk’s engagement with podcasting as an audio storytelling medium allows her to foreground her distinct speaking and singing voice as both a feminist intervention upon the recording industry and as a sonic metaphor for authorial control.
Podcasting Taylor
Authors: Galloway Kate
Published: November 2023

Music podcasts use a variety of listening modes to draw non-musically trained listeners into close readings of songwriting, production, and reception. Taylor Swift has attracted the attention of music podcasters who have devoted individual episodes and entire serial podcast to topics ranging from her celebrity feuds and well-publicized relationships, her autobiographical and deeply referential song texts, her savvy branding strategies and relationships with fans, and her public rejoinders to music industry inequities, such as her Taylor’s Version re-recordings. In the case of several Swift podcasts, these expert listeners are also avid fans, challenge the stereotype that avid pop fans are only amateur listeners. Her fans, notably those who self-identify as Swifties, are also active podcasters. This article is about listening to the sonic environments of fan-driven podcasting and the sonic spaces of fandom through music podcasting. This article engages with the sound and content of fan-driven music podcasting and the listening techniques used by hosts to listen to both the music of the artist where their fandom is centered, as well as the paramusical elements of their star persona and sonic strategies used by hosts to shape a virtual sonic environment where listeners listen with and through the hosts’ embodied listening. Through two case studies, The Swift Talk and Switched on Pop, I demonstrate how fan-driven Swift podcasting is sonically constructed and approaches listening as an inclusive social, analytic, and embodied practice of communicating fan musical knowledge to produce new insights into how listening, songwriting, star persona, and fandom are articulated in fan podcasting.

Gallagher has written the unofficial novelizations of FF7, and Pat Holleman has analysed the development and design of FF7 in his book Reverse Design: Final Fantasy VII. In this conversation, we examine narrative meaning within the soundtrack, compositional techniques within the Compilation of Final Fantasy VII, and RPGs more broadly, music’s relation to lore within FFVII, as well as musical diegesis within the game world.
Emissions and combustion characteristics of torrefied wood pellets
Authors: Fuwape Joseph Adeola , Opara Emmanuel Uchechukwu
Published: November 2023

The influence of torrefaction temperature on the durability, combustion characteristics, and emissions of CO, CO2, NOX, and particulate matter (PM) from biomass pellets was studied. The pellets were torrefied under inert conditions at 225, 250, and 300 °C for 60 min. Physical properties, such as weight loss, fines percentage, pellet durability index (PDI), and water absorption, were evaluated using ISO standards. The weight loss increased with higher torrefaction temperatures. Torrefied pellets had lower water absorption than untreated pellets. Fines percentage increased with torrefaction temperature while PDI decreased. Torrefied pellets at 300 °C had the lowest PDI (82.7%), while 225 °C had the highest (98.0%). The energy density and heating values increased with torrefaction temperature from 22.0 MJ/kg at 225 °C to 29.9 MJ/kg at 300 °C compared to 18.9 MJ/kg for untorrefied pellets. There were reductions in CO, CO2, and NOX emissions with an increase in torrefaction temperature while PM slightly reduced. This study found that torrefied biomass pellets had lower CO2 emissions than raw pellets.
Proanthocyanidin-rich extract from Pinus radiata bark: Mild-alkaline extraction and characterization
Authors: Mun Sung Phil
Published: November 2023

This study assessed the efficacy of mild-alkaline extraction from P. radiata bark in obtaining proanthocyanidin (PA)-rich extracts. When the bark was treated with three types of bases—Na2CO3, NaHCO3, and NaOH—at varying concentrations, the extract yields increased with higher concentrations. When the pH of the extracts exceeded 7, the PA content and antioxidant activity were remarkably reduced. This result suggests that the pH holds a greater effect in the alkaline extraction of the bark rather than the type of base used. Among the bases used, NaHCO3 was selected and the extraction conditions of pine bark were examined at a concentration where the pH of the extract did not exceed 7. The extraction time during mild-alkaline extraction using 0.2% NaHCO3 was reduced compared to water-only extraction at the same temperature. Moreover, the extract yields were over 10% higher than those of water extraction, and the dried extracts exhibited good solubility in water. The mild-alkaline extracts were characterized using FT-IR and 13C NMR spectroscopic techniques, and acidic alcoholysis. Analyses of the spectra of the mild-alkaline extracts showed similarities to that of pure PA and hot water extract. This result indicated that PA in the bark was not significantly affected during mild-alkaline extraction.
Thermal Effects of Alternative Environmentally Friendly Material Instead of Silicone in Battery Modules
Authors: Gökmen Yiğitalp , Gediz Ilis Gamze
Published: November 2023

Nowadays, the demand for electric vehicles is increasing rapidly. One of the most important components of electric vehicles is the battery pack. The reduction of their carbon footprint and recyclability is getting more important. For that reason, the usage of environmentally friendly materials or production methods in their production should be studied. This paper aims to investigate an alternative material for silicone which is used to avoid vibration of the battery cells inside of the battery module. Synthesized Hydrogel, which is not hazardous to the environment, is suggested instead of silicone. Besides its environmentally friendly property, Hydrogel does not use any other curing process like silicone and thus reduces the curing process time and energy that is spent for the application of the silicone which is 100 oC and 5 hours. The heat generation of the battery cells inside of the battery module is also numerically analyzed with electrochemical thermal modeling and the comparison of the silicone and suggested Hydrogel material instead of silicone is performed. The results showed that Hydrogel can be used instead of silicone and this material can remove the curing process during the production of the module and can reduce the carbon footprint of the battery module.

Maintenance of Plan Libraries for Case-Based Planning: Offline and Online Policies
Authors: Gerevini Alfonso Emilio , Saetti Alessandro , Serina Ivan , Loreggia Andrea , Putelli Luca , Roubickova Anna
Published: November 2023

Case-based planning is an approach to planning where previous planning experience provides guidance to solving new problems. Such a guidance can be extremely useful, or even necessary, when the new problem is very hard to solve, or the stored previous experience is highly valuable, because, e.g., it was provided or validated by human experts, and the system should try to reuse it as much as possible. To do so, a case-based planning system stores in a library previous planning experience in the form of already encountered problems and their solutions.
The quality of such a plan library critically influences the performance of the planner, and therefore it needs to be carefully designed and created. For this reason, it is also important to update the library during the lifetime of the system, as the type of problems being addressed may evolve or differ from the ones the library was originally designed for. Moreover, like in general case-based reasoning, the library needs to be maintained at a manageable size, otherwise the computational cost of querying it grows excessively, making the entire approach ineffective.
In this paper, we formally define the problem of maintaining a library of cases, discuss which criteria should drive the maintenance, study the computational complexity of the maintenance problem, and propose offline techniques to reduce an oversized library that optimize different criteria. Moreover, we introduce a complementary online approach that attempts to limit the growth of the library, and we consider the combination of offline and online techniques to ensure the best performance of the case-based planner. Finally, we experimentally show the practical effectiveness of the offline and online methods for reducing the library.
Maximisation of Admissible Multi-Objective Heuristics
Authors: Haslum Patrik , Wang Ryan Xiao
Published: November 2023

In multi-objective (MO) heuristic search, solution costs, as well as heuristic values, are sets of multi-dimensional cost vectors, representing possible non-dominated trade-offs between objectives. The maximum of two or more such vector sets, which is an important operation in creating informative admissible MO heuristics, can be defined in several ways: Geißer et al. recently proposed two MO maximum operators, the component-wise maximum (comax) and the anti-dominance maximum (admax), which represent different trade-offs between informativeness and computational cost. We show that the anti-dominance maximum is not admissibility-preserving, and propose an alternative, the “select one” maximum (somax). We also show that the comax operator is the greatest admissibility-preserving MO maximum, and briefly investigate its efficient implementation. The conclusion of our experimental results is that somax achieves a trade-off similar to that intended with admax – cheaper to compute but less informed – also when compared to an improved comax implementation.
Study on performance of geocell-reinforced red clay subgrade
Authors: Luo X. W. , Lu Z. , Zhang J. B. , Yao H. L.
Published: November 2023

Three comparative treatment plans are used to study the effect of red clay subgrade reinforced with geocell. Multiple subgrade test methods including Benkelman beam, portable falling weight deflectometer, dynamic cone penetrometer and standard vehicle load tests are adopted in the field tests. Test results show that the application of geocell in red clay subgrade can enhance the overall stiffness and strength of the subgrade. The mechanism of geocell in the subgrade is studied. Geocell can provide added confinement to the subgrade soil. Compared with the red clay subgrade without geocell reinforcement, for the red clay subgrade reinforced with 0.1 m-high geocell and 0.05 m-high geocell, the rebound modulus increases by 65% and 33%, the dynamic modulus increases by 69% and 38% and the penetration decreases by 51.7% and 40.4%, respectively. A hard shell layer is formed in the subgrade when it is reinforced with geocell. The geocell-reinforced layer mainly plays the role of stress diffusion. It not only can reduce the additional stress in the subgrade but can also diminish the influence of the depth of the vehicle load.

Published: November 2023

The development of modern technological processes for processing natural hydrocarbon raw materials and the optimal operation of existing production facilities is impossible without the use of modeling programs that have a high accuracy in describing the parameters of technological processes and allow studying these processes without significant material and time costs. Such model studies are of great importance not only for the design, but for the functioning of existing industries, as they allow us to take into account the influence of external factors on the performance of existing industries. Currently, a large number of software tools for modeling chemical technological processes are available to process engineers. When designing process flow diagrams for oil refineries and petrochemical plants, different departments of design institutes perform different types of work, using different software. The same applies to the so-called BIM - technologies implemented by installation and technological departments and the subsequent use of constructed installation diagrams in the existing production. Thus, this article discusses the problem of transferring data from the UniSim Design technological process modeling program to the AVEVA Everything3D computer-aided design systems for further use in the design process of the obtained design data of selected technological equipment. The technological process of steam generation was simulated in the UniSim Design program. An original module for transferring data to AVEVA Everything3D has been developed. The article presents the results of the module.

Published: November 2023

The choice of hard-to-recover reservoir (HRR) engineering technologies is one of the actual problems facing oil companies in the Russian Federation and the World. In order to increase the efficiency of the development of such fields various methods for production intensification are used to obtain an economically profitable industrial oil inflow. It is possible to use surfactant flooding to solve this problem. The surfactant efficacy results from the fact that aqueous surfactants solutions even at low concentrations dramatically decrease the oil/water/rock interfacial tension that results to changing wettability, allowing to increase the oil inflow.The purpose of this work is to study an alternative method of testing the effect of surfactant solutions on oil recovery. The method consists in mass testing using a laboratory petrophysical centrifuge to identify the most promising solutions, followed by the classical filtration method. The method of centrifugation is based on the substitution of one fluid in the pores of the core sample by another, occurring at a pressure difference at the boundary of the two phases under the action of centrifugal force. The suggested method will allow massively and in a short time to identify the most effective solutions for specific geological conditions.To carry out this work, three surfactant solutions were selected that were tested for resistance to mineral aggression and temperature, surface tensions and phase behaviors were determined. The object of the study was the core material of the formations of the AS, BS and YuS groups of one of the deposits of Western Siberia. Two series of experiments were carried out: classical filtration tests and centrifugation of core samples under conditions of initial and residual oil saturation.The results of the experiments have shown the effectiveness and prospects of using the centrifugation method for mass testing of surfactant solutions as displacing agents. The described method is express and cannot completely replace the classical filtration experiment due to non-compliance with an important criterion – the thermobaric conditions of the reservoir.

The term corpus linguistics is now very popular. The compilation of a corpus of language texts is included among the priority areas of work of the academies. In paremes formed on the basis of the name “insect,” homonymy is observed between words that resemble the name of the insect and units that are homophones with the lexeme denoting the name of the insect. Direct homonymy is expressed by the lexemes mole, worm, donkey (dial. scorpion), and “burga” - “burgan” act as homophones. The creation of text corpora is considered by a number of scientists as the most important humanitarian task of linguistics. This article explains the concept of corpus linguistics and discusses its theoretical foundations.

Published: November 2023

Cholesterol is a sterol, synthesized by animal cells and vital lipid molecule for human cells (animal) and is also a component of the diet, being present in food of animal origin. Its main function is to maintain the integrity and fluidity of cell membranes and to serve as a precursor for the synthesis of substance that are vital for the organism including steroid hormones, bile acids and vitamin D. animal cells acquire cholesterol from extracellular lipoprotein and form new synthesis of cells. Dietary cholesterol comes exclusively from animal sources, it is naturally present in our diet and tissues. Cholesterol is synthesized in the human body in order to maintain a stable peel when dietary intake is low, given the necessity for cholesterol, very effective intestinal uptake mechanisms bile acid and cholesterol reabsorption cycles exist1. Conversely carbohydrates are poorly absorbed and indeed rapidly excreted. Dietary cholesterol content does not significantly influence cholesterol value, which are regulated by various nutritional. Factors that influence cholesterol absorption (or) synthesis. Recent study data do not support a link between dietary cholesterol and cardio vascular diseases2.

Authors: Fathurrahman Andiyoga  , Agus Joko Susanto  , Arifin
Published: November 2023

Background: Human Immunodeficiency Virus (HIV) is a retrovirus subgroup of lentivirus family that has RNA genetic characteristics that attack the body's immune system, especially infecting Cluster Differential Four (CD4) lymphocytes and replicating according to the host's DNA. Vitamin D is important in stimulating innate immunity. Availability of vitamin D has an important role to improve the nutritional status of HIV/AIDS patients, improve the immune system, and improve prognosis. Research Objectives: To assess the effect of administration of vitamin D3 tablet therapy on serum vitamin D 25-OH levels, hemoglobin levels, body mass index (BMI), and CD4/CD8 ratio in HIV/AIDS infected patients who have been treated with antiretrovirals (ARV). Methods: This study was a cross-sectional study using 40 samples of HIV patients who were routinely controlled at the VCT polyclinic at Dr. Moewardi who received regular antiretrovirals. The inclusion and exclusion criteria are intended to obtain samples that are currently in HIV stages I and II so that it is expected to reduce other factors that cause bias levels of vitamin D apart from the chronic inflammatory process that occurs in HIV-infected patients. Patients who have come informed their consent to take blood samples during one of their visits to the VCT poly to check BMI, serum vitamin D (25-(OH)), and routine blood to determine the value of hemoglobin and the CD4/CD8 ratio. The statistical test uses an analysis of the difference in the average of the two groups. Results: The results of testing the mean difference between the two groups of serum levels of vitamin D 25-OH in the Vitamin D3 treatment and control groups showed a value of Z = -2.277 (p = 0.023). The results of the different test mean that the two groups of hemoglobin in the Vitamin D3 treatment group and the control showed a value of Z = -3.484 (p = 0.001). The results of different tests mean that the two BMI groups in the Vitamin D3 treatment group and the control group show a value of t = -5.098 (p = 0.001). The results of the mean difference test of the two CD4/CD8 ratio groups in the Vitamin D3 treatment group and the control group showed a value of t = -6.203 (p = 0.001). Conclusion: Administration of 2000 IU vitamin D3 tablets can increase serum vitamin D 25-OH levels, hemoglobin, BMI, and CD4/CD8 ratio in HIV/AIDS-infected patients treated with antiretroviral (ARV).

En México, las Redes de Tutoría surgieron en los 90s como respuesta a la necesidad de impulsar el aprendizaje autodirigido en comunidades marginadas. Estas redes, ancladas en el diálogo equitativo, conectan los intereses de los estudiantes con las habilidades de los tutores. En las telesecundarias, esta metodología se expandió, logrando notables mejoras en competencias de español y matemáticas. Con el liderazgo del Dr. Gabriel Cámara durante más de 25 años, estas redes evolucionaron y se ampliaron. Este documento traza la historia, la estrategia, la implementación y el crecimiento de las redes de tutoría desde sus inicios hasta la actualidad.
Droughts, Women and Indigenous People in Chile: Assessing the Impacts on Income and Employment

Climate change is a pressing issue, affecting the lives of all people across the world. However, poorer and excluded communities are usually more affected, especially in low-income countries. Among them, women but particularly indigenous groups in rural areas seem to bear the bulk of the impacts produced by climate change and its many manifestations. We study the relationship between droughts and incomes and labor market outcomes in Chile over the period 1990-2017, focusing in particular on indigenous women. Our results show that overall indigenous women are the group most severely affected by droughts, decreasing their income, their probability of working in agriculture, and increasing their likelihood of working as an unpaid family worker or being out of the labor force. Results are robust to the use of different variables to measure droughts and to different econometric specifications. Our study corroborates the existence of marked heterogenous effects of climate change on different population groups and the vulnerability of indigenous communities to these shocks.
Magnesium at physiological pregnancy and at its complications

Published: November 2023

Sources of literature on the role of the trace element magnesium and the assosiation with calcium in physiological processes in the body of reproductive aged women and pregnant women, the importance of its main functions and role in preventing the main pregnancy complications were analyzed.

Magnesium is the fourth most important extracellular cation after sodium, potassium and calcium and the second intracellular cation in importance after potassium. Many researchers have proven the participation of magnesium in almost everyone important functions in the body. Magnesium performs the following functions which are closely interconnected: metabolic, energetic, enzymatic, cardiovascular, antithrombotic, vascular, neuroprotective, structural, is an antagonist of calcium and an agonist of NMDA receptors. Magnesium realizes its functions in close interaction with cations of sodium, potassium and calcium. It acts as a calcium antagonist. It should be noted attention to the understanding of the interaction of divalent cations-competitors of magnesium and calcium. Calcium has complex influences on interaction of magnesium with blood proteins, reduces its concentration, which can affect physiological processes during pregnancy and in non-pregnant women.

Today, magnesium is used only for prevention and treatment of eclampsia, in which anticonvulsants are commonly used ineffective. It can be assumed that different convulsive states have different intracellularly or extracellularly magnesium concentration is important in the pathogenesis and occurrence of eclampsia. Determination of magnesium concentration never was indicated in the recommendations for the management of preeclampsia. Magnesium use is insufficiently substantiated in cases of uterus contraction activity in any conditions (threat of abortion, premature birth) and prevention of pathological blood clot formation (as causes of multiple complications of pregnancy), neuroprotective effect on a child.

The role of magnesium in the production of steroid hormones has been proven. However, this effect remains unrealized in obstetrics and gynecology practice.

Data from literature sources given in the article help justify the use of magnesium and analyze its interaction with calcium during pregnancy.

A clinical case of the course of pregnancy by trimesters of gestation, childbirth, postpartum (early, late) in a woman with anemia and helicobacteriosis is described. The materials of the medical documentation were analyzed, the peculiarities of the course of pregnancy, childbirth, the postpartum period, laboratory indicators, echography, fibrogastroduodenoscopy were determined.A 32-year-old pregnant woman was hospitalized at 33вЂ“34 weeksвЂ™ gestation, IV pregnancy. According to the clinical and laboratory examination, B12-folate-iron-deficiency anemia was diagnosed against the background of Helicobacter pylori (Hp) infection (titers of total IgG, IgA, IgM antibodies to Hp antigens (coefficient of positivity) were 7.65). The patient received anti-anemic, nutrient therapy before and after childbirth. Childbirth was termed and physiological. The child was born with a body weight of 3000 g and an Apgar score of 8 points.The woman was examined again 2 months after labor. Anemia of II degree was diagnosed, the Hp coefficient of positivity was increased up to 14.57. It was prescribed anti-anemic therapy aimed at eradicating Hp in accordance with the Maastricht V Consensus (2015) and stabilizing metabolic processes. Two months after treatment, the Hp coefficient of positivity decreased by 2.3 times and the levels of hemoglobin, ferritin, vitamin B12, and folic acid increased to reference values.Conclusions. It is advisable to determine the total titers of IgG, IgA, IgM antibodies to Hp antigens (coefficient of positivity) as the etiological factors of anemia in pregnant women, especially with diseases of the gastrointestinal tract, hepatobiliary system and resistance to anti-anemic therapy. Helicobacteriosis affects the exchange of iron and vitamins of group B, while anemia occurs with more severe manifestations and is resistant to anti-anemic drugs.Full treatment of pregnant women with helicobacteriosis is difficult due to the possible risk of negative effects of etiotropic drugs on the fetus. Therefore, it is important to plan a pregnancy, since timely detection of infectious factors before pregnancy and full-fledged therapy help to reduce the frequency of gestational complications.

Since the outbreak of the COVID-19 pandemic, the education sector has been seriously impacted, leading to the migration of academic offerings to online learning mode. This investigation focuses on the experiences of engineering students offering Thermodynamics as a subject at a University of Technology in South Africa, as they transition to online academic platforms. Resource availability, such as a quantitative learning platform and access to computer laboratories on campus, as well as other institutional supports, were evaluated. A total of 100 students offering the Engineering Thermodynamics module participated in the surveys and responded to the questionnaire. The study identified various constraints that affected the students' learning experience due to the online learning format, including connectivity issues, time management, inadequate university support, limited understanding of online learning platforms, and high cost of data. Various strategies were recommended to address the challenges faced by engineering students during the transition to online learning. By implementing these strategies, the online learning experience can be enhanced for students facing similar challenges in their academic pursuits.
O auxílio emergencial como política anticíclica em tempos de crise pandêmica: um estudo comparativo de Belém em relação ao Brasil a partir dos principais índices nacionais e do suporte teórico de Keynes (Paper 560)

O presente artigo procurou investigar a importância do programa governamental de transferência de renda mínima, denominado “auxílio emergencial”, que foi utilizado durante a pandemia de Covid-19, tendo como base para análise um estudo comparativo da cidade de Belém em relação ao Brasil, a partir dos principais índices nacionais e do suporte teórico do economista John Maynard Keynes. O auxílio emergencial tinha como principal objetivo mitigar os impactos sociais e econômicos causados pela crise pandêmica, isto é, prover suporte aos trabalhadores informais, pequenos empresários e contribuintes do INSS, que foram afetados durante a pandemia. Os dados da análise incluíram o Produto Interno Bruto (PIB), o Produto Nacional Bruto (PNB), a inflação, preços da cesta básica e índices de pobreza e extrema pobreza em uma pesquisa exploratória qualitativa. A principal conclusão é que o auxílio emergencial se mostrou uma política anticíclica demasiadamente importante, pois ajudou a mitigar os efeitos da inflação do período pandêmico e serviu como “colchão” de proteção social aos mais necessitados, já que o incremento na renda das classes mais humildes possibilitou um relativo aumento do poder de compra e consumo, confirmando a importância do uso e aplicação do auxílio emergencial para atenuar os efeitos da pandemia de Covid-19.Palavras-chave: Auxílio emergencial.
