Elimination of Singulariries in Causal Green Functions for Generalized Klein-Gordon and Dirac Equations on Light Cone
Authors: Kulish Yu. V.
Published: December 2023

Klein-Gordon and Dirac equations are generalized to eliminate divergences in the integrals for Green functions of these equations. The generalized equations are presented as products of the operators for the Klein-Gordon equation with different masses and similarly for the operators of the Dirac equation. The homogeneous solutions of derived equations are sums of fields, corresponding to particles with the same values of the spin, the electric charge, the parities, but with different masses. Such particles are grouped into the kinds (families, dynasties) with members which are the particle generations. The Green functions of derived equations can be presented as sums of the products of Green functions for the Klein-Gordon equation (the Dirac equation) and the definite coefficients. The sums of these coefficients equal zero. The sums of the products of these coefficients and the particle masses to some powers equal zero too, i.e. for these coefficients some relations exist. In consequence of these relations the singularities in Green functions can be eliminated. It is shown that causal Green functions of derived equations сan be finite in all the space-time. This is possible if minimal quantities of the generations Nb and Nf for the bosons and the fermions equal 3 and 6, respectively. An absence of singularities in the Green functions on light cone is related to an attenuation of particle interactions on short distances. It is shown explicitly for the generalization of the Yukawa potential.
About the Values of the Stray Environment Fields-to-Toroidal-Coil Magnetic Field Ratio in the Uragan-2M Torsatron
Authors: Lesnyakov G. G. , Shapoval A. N.
Published: December 2023

The values of stray environment magnetic fields of the Uragan-2M torsatron have been determined using local magnetic sensors, and also, the electron beam injection in the additional toroidal magnetic field (16 coils, making up 60% to 76% of the total toroidal field). In the stationary toroidal magnetic field, the turns of the electron beam have been visualized by scanning the poloidal vacuum chamber cross-section with a luminescent rod. The measurements have made it possible to determine a decrease in the ratio of stray environment vertical magnetic fields to toroidal-coil magnetic field down to z/BT ≈ 1×10-3 at magnetic fields ВТ = 0.0225 - 0.15 T, and also, to estimate the prospect of the ratio decrease to z/BT ≈ 1×10-4 as the toroidal magnetic field increases up to ВТ ≥ 0.45 Т.

Published: December 2023

In this paper, we aim to describe the cosmic late-time acceleration of the Universe in f(R,Lm) gravity framework proposed by Harko (2010) with the help of an equation of state for strange quark matter. To achieve this, we adopt a specific form of f(R,Lm) gravity as f(R,Lm) =R/2}+ Lnm, where n is arbitrary constants. Here we utilize a hybrid scale factor to resolve the modified field equations in the context of f(R,Lm) gravity for an isotropic and homogeneous Friedmann–Lemaître–Robertson–Walker (FLRW) metric in presence of strange quark matter (SQM). Also,  we analyze the dynamics of energy density, pressure and the state finder parameters and explained the distinctions between our model and the current dark energy models in the presence of SQM. We observed a transition from an accelerating to a decelerating phase in the Universe, followed by a return to an accelerating phase at late times. Also, we analyzed the state finder diagnostic as well equation of state parameter and found that the model exhibited quintessence-like behavior. The conclusion drawn from our investigation was that the proposed f(R, Lm) cosmological model aligns well with recent observational studies and effectively describes the cosmic acceleration observed during late times.

Published: December 2023

The present work aims to study the previously unstudied Ultraluminous X-ray sources (ULXs) in the galaxy NGC 3585 at its various epochs of Chandra observation. We report here the detection of two new ULXs viz. CXOUJ111306.0-264825 (X-1) and CXOUJ111325.3-264732 (X-2) with their bolometric luminosity > 1039erg s−1 in its various Chandra observations. X-1 was found to be a spectrally hard ULX in both the epochs where it was detected. However in the ULX, X-2, a slight hardening of the spectra was observed within a period of 17 years. Assuming isotropic emission and explained by disk blackbody model, the spectrally softer epoch of X-2 with an inner disk temperature, kTin ∼ 0.79 keV and bolometric luminosity ∼ 2.51 × 1039erg s−1 implies for X-2 to be powered by a compact object, necessarily a black hole of mass, MBH ∼ 44.85+82.11−25.92M⊙ accreting at ∼ 0.42 times the Eddington limit. The Lightcurve of X-1 and X-2 binned at 500s, 1ks, 2ks and 4ks has shown no signature of short-term variability in both the ULXs in kilo-seconds time scales. Overall, both the detected ULXs seem to be almost static sources both in long-term (years) as well as short-term (kilo-seconds) time scales with the presently available Chandra Observations.

Authors: Borah Keshab , Konch Jadav , Chakraborty Shyamanta
Published: December 2023

A numerical study of the heat and mass transfer of a micropolar nanofluid flow over a stretching sheet embedded in a porous medium is carried out in this investigation. The main objective of this work is to investigate the influence of Arrhenius activation energy, heat source and viscous dissipation on the fluid velocity, microrotation, temperature, and concentration distribution. The equations governing the flow are transformed into ordinary differential equations using appropriate similarity transformations and solved numerically using bvp4c solver in MATLAB. Graphs are plotted to study the influences of important parameters such as magnetic parameter, porosity parameter, thermophoresis parameter, Brownian motion parameter, activation energy parameter and Lewis number on velocity, microrotation, temperature and concentration distribution. The graphical representation explores that the velocity of the liquid diminishes for increasing values of magnetic parameter, whereas the angular velocity increases with it. This study also reports that an enhancement of temperature and concentration distribution is observed for the higher values of activation energy parameter, whereas the Lewis number shows the opposite behavior. The effects of various pertinent parameters are exposed realistically on skin friction coefficient, Nusselt and Sherwood numbers via tables. A comparison with previous work is conducted, and the results show good agreement.

Authors: Senini Lina Wafaa Belhadj , Boussoufi Mustpaha , Sabeur Amina
Published: December 2023

The objective of this study is to investigate, through numerical simulations, the flow and heat transfer characteristics of Al2O3, Cu, TiO2, and SiC water-based nanofluids flowing over micro-cylinder groups arranged in an inline configuration. The simulations were carried out under laminar flow conditions, and the analysis considered seven different low values of the Reynolds number, with a constant volume fraction of 2%. The aim of this investigation was to determine how nanofluids, i.e., suspensions of nanoparticles in water as the base fluid, can affect the pressure drop and heat transfer performance in micro-cylinder groups. To accomplish this, the finite volume method was employed to evaluate the impact of the nanofluids on pressure drop and heat transfer characteristics in the micro-cylinder groups. The study results demonstrate that, for all the nanofluids studied, the pressure drop and friction factor of the micro-cylinder groups increased with increasing Reynolds number. This behavior can be attributed to the interaction between the nanoparticles and the wall, which results in an increase in friction. Furthermore, the Nusselt number was found to increase with increasing Reynolds number. The SiC/Water nanofluid exhibited the highest Nusselt numbers among the four nanofluids tested, indicating that it provides better heat transfer performance than the other nanofluids. These results are consistent with experimental findings, indicating that the numerical simulations were accurate and reliable.

Published: December 2023

The article is devoted to nonlinear effects in lithium niobate crystals. The possibility of using digital holographic interferograms obtained with the help of laser radiation of different duration at different moments of time for the reconstruction of dynamic phase changes is shown. Holograms were recorded on lithium niobate crystals doped with iron ions in various concentrations using He-Ne and He-Cd lasers, and the diffraction efficiency was calculated. Also, the effect of gamma radiation on the optical properties of LiNbO3 and LiNbO3:Fe crystals was studied. At the same time, it was determined that the band gap of the samples decreases, as a result of which the refractive index, absorption coefficient and photorefractive sensitivity increase several times.

Authors: Kukurudziak Mykola S. , Lipka Volodymyr M.
Published: December 2023

The paper investigates the influence of the electrophysical characteristics of silicon on the final parameters of photoelectronic elements using p-i-n photodiodes as an example. It has been found that photodiode samples made on the basis of silicon with a higher resistivity are more prone to the formation of inversion channels at the oxide-semiconductor interface. Also, the dark current and responsivity of such photodiodes reach saturation at a lower voltage. It has also been shown that silicon-based photodiodes with a longer lifetime of non-basic charge carriers have lower dark current values. It has been shown that products with crystallographic orientation [111] have a much lower density of surface dislocations after technological operations than in the case of silicon with orientation [100]. It was also found that materials with different crystallographic orientations have different phosphorus diffusion coefficients. It has been experimentally established that a silicon oxide film grows faster on the surface of crystallographic orientation silicon [111] than on the surface of crystallographic orientation silicon [100]. This is due to the difference in the surface density of silicon atoms inherent in different crystallographic planes.

Published: December 2023

Capacitance spectroscopy was used to study the capacitive-voltage characteristics of multilayer structures with a Si-SiO2 transition layer in Al-SiO2-n-Si type samples fabricated by the thermal oxidation of a semiconductor. It is shown that the inhomogeneous distribution of the density of surface states is a localized electroactive center at the very semiconductor-dielectric interface, due to over-barrier charge emission or thermal ionization of impurity centers.

Due to the necessity of reducing the reliance on fossil fuels, several systems are considered to be alternative and/or additional support for the existing battery material. In this report, structural and electronic properties of aluminium oxide (Al2O3) and aluminium sulfide (Al2S3) with hexagonal symmetry (α-phase), are investigated by utilizing density functional theory technique based on r++SCAN functional. The calculated lattice parameter and insulating gap for both systems are well matched with previous experimental studies and display higher accuracy compared to the results from local density approximation (LDA) and generalized gradient approximation (GGA) studies. The calculated insulating gap values are 10.3 eV and 4.1 eV for α-Al2O3 and α-Al2S3 respectively. For α-Al2O3 system, we observed hybridized s-p-d orbital of Al-O in the conduction states, consistent with the interpretation of past X-ray Absorption Near Edge Structure (XANES) data. Finally, the bulk and young modulus for α-Al2O3 are determined to be 251 GPa and 423 GPa which is very close to the known experimental values of 280 GPa and 451 GPa.

In this work, defect absorption spectra for defects characteristic of hydrogenated amorphous silicon are theoretically studied. It is shown that in order to determine defect absorption spectra using the Kubo-Greenwood formula, the indefinite integral in this formula must be written in a certain form. It was discovered that electronic transitions involving defect states are divided into two parts depending on the energy of absorbed photons. The values of the partial defect absorption spectrum at low energies of absorbed photons have almost no effect on the overall defect absorption spectrum. It has been established that the main role in determining the defect absorption spectrum is played by partial spectra determined by optical transitions of electrons between allowed bands and defects. It is shown that with a power-law distribution of the density of electronic states in allowed bands, the spectra of optical transitions between them and defects do not depend on the value of this power.

Published: December 2023

The effect of thermal treatment on the behavior of samarium atoms introduced into silicon during the growth process was studied using the method of transient capacitive deep-level spectroscopy (DLTS). It has been shown that various high-temperature treatments lead to the activation of samarium atoms in the bulk of n-Si and the formation of deep levels. The energy spectrum of deep levels arising during heat treatments has been determined. The dependence of the efficiency of formation of these levels in n‑Si on the processing temperature has been studied. It was found that the higher the content of samarium atoms in the bulk of silicon at the same high-temperature treatment temperature, the higher the concentration of the deep level EC–0.39 eV. From this, we can conclude that the EC–0.39 eV level is associated with the activation of samarium atoms in the n-Si volume.

Published: December 2023

The article presents the results of the theoretical study of the plasma density axial distribution in a stationary gas discharge sustained by the eigen dipolar wave that propagates in a long cylindrical plasma-metal structure. The discharge structure consists of a column of magnetized non-uniform plasma placed in the metal waveguide of variable radius. The study of the gas discharge is carried out within the framework of the electrodynamic model, in which the main attention is paid to the electrodynamic part of the model. To describe the processes that take place in plasma, the model equations are used. The influence of the metal waveguide inhomogeneity along the structure and the plasma density radial non-uniformity on the phase characteristics of the dipolar wave, its spatial attenuation, the field components radial distribution, the axial distribution of the plasma density sustained by this mode are determined. It is also analysed the condition for the discharge stability and find the regions, where dipolar mode can sustain the stable discharge. The obtained results can be useful for various technological applications.

Two series of multilayer coatings with different numbers of bilayers (268 and 536, respectively) were synthesised using the cathodic vacuum-arc deposition (CVAD) with the simultaneous sputtering of two different cathodes. The first cathode was made of the multicomponent TiZrSiY material, and the second one was made of technical niobium. The coatings were condensed in a nitrogen atmosphere at a constant negative bias potential applied to the substrate. The resulting coatings have a distinct periodic structure composed of individual layers of (TiZrSiY)N and NbN with the thicknesses determined by the deposition interval (10 or 20 s, respectively). The total thicknesses of the coatings determined by the number of bilayers were 11 and 9 microns, respectively. The formation of polycrystalline TiN and NbN phases with grain size comparable to the size of the layers has been identified for both series of coatings. The layers exhibit a columnar structure growth with a predominant orientation (111). The hardness of the experimental coatings depends on the thickness of the layers and reaches 39.7 GPa for the coating with the smallest layer thickness. The friction coefficient of the obtained coatings varies from 0.512 to 0.498 and also depends on the thickness of the layers. A relatively large value of the friction coefficient is due to high roughness and the presence of a droplet fraction on the surface as well as in the volume of the coatings.

Published: December 2023

Now, in difficult economic conditions in Ukraine, the issue of effective cost management is becoming relevant for enterprises, taking into account the opportunities to stimulate resource savings, forecasting and controlling costs according to the “Expenses-output-profit” system.

Now in our country there is a question of ensuring the stable development of enterprises. First of all, this is due to the military aggression against Ukraine. Business has to resist internal and external negative processes taking place both in the state and outside it.

Entrepreneurs are increasingly in need of support and assistance from economically stable partners. The ability of an enterprise to effectively conduct economic activities is marked by the level of its costs and prime cost, which characterize its ability to provide such a level of financial stability sufficient to avoid the risks of bankruptcy and unprofitability of economic activity.

The above gives an opportunity for stable and dynamic development of Ukrainian enterprises. It is the choice of optimal aspects and methods of cost management that creates the basis for economic stability and competitiveness of enterprises in the world market. Market conditions are increasingly increasing the requirements for the efficient conduct of business activities and maximization of income. This can be achieved in two ways. The first is by increasing income (increase in product prices). The second is the cost optimization method.

It should be noted that in the context of automating the activities of enterprises in the world, the cost optimization procedure based on business process modeling is of particular importance. The issue of cost management in this context still needs a detailed study. Reliable cost estimates are essential for making the right decisions and taking the best action. Therefore, this task requires highly qualified employees of the company to master the techniques and methods of applying certain elements of the cost management structure to solve certain situations. Modern Ukrainian enterprises still need such employees.

In difficult economic conditions for our state, the introduction of more adapted to domestic conditions and the specifics of doing business is important methodologically, due to the need for uninterrupted monitoring of costs and support for the competitiveness of the enterprise.
Investigating SHP and PCSK9 Interactions in Cholesterol-Mediated Cardiovascular Diseases: A Research Protocol
Authors: Bae Moon Young , Kim Rachel , Wang Judy
Published: December 2023

Introduction: Improper cholesterol metabolism results in accumulation of low-density lipoproteins (LDL). High levels of LDL cholesterol deposits in blood vessels, forming plaques and contributing to various cardiovascular diseases (CVD). The nuclear farnesoid X receptor (FXR) regulates the transcription of genes involved in cholesterol metabolism and is a therapeutic target for cholesterol dysregulation. Studies conducted on immortalized human hepatocytes demonstrate FXR signaling-induced downregulation of proprotein convertase subtilisin/kexin type 9 (PCSK9) expression. PCSK9 is an LDL receptor-degrading enzyme whose upregulation is implicated in cholesterol-mediated diseases. Specifically, the FXR target gene SHP (small heterodimer partner) is a transcriptional regulator that has been implicated in an inverse relationship with PCSK9 expression. The biomolecular mechanism mediating this relationship has not been explored, meriting investigation into a potential novel axis of cholesterol metabolism. We hypothesize that SHP is a direct repressor of PCSK9 transcription. Methods: To investigate, we will knock out SHP expression in the liver hepatocyte cell line AML12 using small interfering RNAs (siRNAs). To confirm SHP knockout on transcriptomic and proteomic levels, reverse transcription quantitative PCR (RT-qPCR) and Western blotting will be performed. To assess SHP binding to the promoter region of PCSK9, an electrophoretic mobility supershift (EMSA) assay will be performed on unstimulated or chenodeoxycolic acid (CDCA)-stimulated AML12 cells that have undergone SHP or control knockouts. Western blotting will quantitate PCSK9 protein expression following SHP knockout in CDCA-stimulated and unstimulated conditions. Results: Results from EMSA are expected to demonstrate SHP binding to the promoter region of PCSK9 in a transcription factor complex to repress transcription. SHP knockout models are expected to show upregulated PCSK9 expression at transcriptomic and proteomic levels. Discussion: If successful, our study presents a novel perspective on cholesterol metabolism by characterizing the inhibitory effect of SHP on PCSK9 expression. This underlines the critical role of FXR signaling in PCSK9 regulation, and knockout models and assay techniques provide valuable evidence of this regulatory role. Conclusion: This study will establish an enhanced understanding of the SHP/PCSK9 pathway within broader pathways of cholesterol metabolism. Further research may explore therapies targeting the SHP/PCSK9 pathway to manage CVD downstream of cholesterol dysregulation.

Formation of the Relationship between the Exchange Rate and the Investment Yield of Pension Assets in Kazakhstan: Causes and Consequences
Authors: Dodonov V. Yu.
Published: December 2023

The efficiency of pension asset management, reflected in their performance, determines the stability of the funded pension system of Kazakhstan, and also has the potential to significantly affect the budget process, since the state guarantees recipients a positive real return on their pension savings and compensates from the budget for losses incurred during periods when inflation exceeds the nominal rate of return. The need to ensure a positive real return on pension assets managed by the National Bank of Kazakhstan determines not only the high relevance of the issue of investment management itself, but also other aspects that affect the return, including changes in the exchange rate of the Kazakhstani tenge. The subject of the article is the impact of the tenge exchange rate on the profitability of pension assets, which can be very significant, since it forms one of the main components of investment income — income from foreign currency revaluation. This influence can also act as a factor in the formation of the tenge exchange rate during periods when the real return of pension assets decreases due to the negative situation in the financial markets and high inflation, and this thesis reflects the scientific novelty of the article. The assessment of the hypothesis about the formation of the relationship between the exchange rate of the Kazakhstani currency and the investment yield of pension assets is the aim of this work, and the identification of the main causes and consequences of this phenomenon is its task. Comparative and correlation analysis of indicators of investment return of pension assets, changes in the exchange rate of the Kazakhstani currency, parameters of the external sector and others were used as research methods. The results of the analysis confirm the existence of a relationship between the indicators of profitability of pension assets and the tenge exchange rate, and allow us draw the conclusion that this profitability has an indirect impact on the formation of the Kazakhstani currency exchange rate over the past few years, which has been characterized by non-standard dynamics in the context of a significant improvement in the external economic environment.

Authors: Dash A.S. , Mishra U.
Published: December 2023

Due to new technical advances, the machine can think as a person-investor and express its reaction to readily available financial information. Forecasting models for the Indian stock market can be developed based on the analysis of these sentiments. The purpose of the study is to identify gaps in existing approaches to the analysis of sentiments and models of forecasting trends in the Indian stock market, which can improve the accuracy of the prediction of the dynamics of Indian stocks. The paper presents an overview of the literature on the analysis of sentiments of financial information using lexical methods, machine learning methods and forecasting for the Indian stock market based on sentiment analysis data. The scientific works, conference reports, dissertations, books and articles published by scientists for the period from 2015 to 2021 are considered. The datasets published in Indian Stock Exchanges suggest increasing participation of retail investors in the Indian Stock market in recent times. To help investors in decisionmaking, various prediction models are available based on the financial information. The results of the survey showed that investors’ attitudes based on the microeconomic and macroeconomic information associated with stocks influence the movement of the stock price. Therefore, forecasting a future trend or price requires a sentiments analysis based on available financial information. It was concluded that using machine learning to extract sentiment from financial data allows for more accurate forecasts than sentiment analysis based on vocabulary. The results of this study can be useful for students and new professionals in the field of financial information data analysis and stock market predictions who want to get connected with this area, identify problem concerns, and develop models for predicting decision-making.
Current Waste Management in Banks from 11 Asian Countries vs Sberbank ESG Reporting
Authors: An J. , Mikhaylov A. Yu.
Published: December 2023

The relevance of the topic lies in the fact that the level of competitiveness of a bank in waste management will have an increasing impact on its ESG ratings in the future. The purpose of this paper is to improve waste management in a bank (mainly faulty office equipment and paper waste). However, not all banks use active management methods in waste management, so this article offers recommendations for the successful management of key indicators. The article uses data on waste from banks in Bangladesh, China, Indonesia, Kuwait, India, Malaysia, Nepal, Pakistan, Sri Lanka, the UAE, and Vietnam. The objectives of the study include: identification of the essence of the competitiveness of waste management in a bank; consideration of the types of competitiveness of waste management; assessment of the impact of blockchain technology on the competitiveness of waste management; assessment of minimizing waste management costs in a bank. A method for waste composition and waste export based on statistical analysis and a regression model. It used data about the current waste management activities of a bank. This study uses data from an annual time series covering the period from 2013 to 2021. The results of the study confirm that the problem of electronic waste of banks in Asia can be solved by increasing financing and a complete analysis of bank waste. There are points of novelty in the article: (1) the essence of the competitiveness of waste management in a bank is determined, which consists in the recycling of most waste and not in their disposal; (2) the ideas of the competitiveness of waste management are considered in Sberbank; (3) the impact of blockchain technology on the competitiveness of waste management in banks is assessed; (4) an assessment of the competitiveness of waste management in a commercial bank is given. In order to better understand the factors influencing the production of e-waste in the region, the study focuses on the significance of addressing the rising problem of e-waste in Asia and the need for better collection and analysis of waste data in a bank. The main conclusion is the need to recycle waste and increase recycling costs in the future, which is the most environmentally friendly option compared to incineration.
Treatment of Missing Market Data: Case of bond Yield Curve Estimation
Authors: Makushkin M. S. , Lapshin V. A.
Published: December 2023

Missing observations in market data is a frequent problem in financial studies. The problem of missing data is often overlooked in practice. Missing data is mostly treated using ad hoc methods or just ignored. Our goal is to develop practical recommendations for treatment of missing observations in financial data. We illustrate the issue with an example of yield curve estimation on Russian bond market. We compare three methods of missing data imputation — last observation carried forward, Kalman filtering and EM–algorithm — with a simple strategy of ignoring missing observations. We conclude that the impact of data imputation on the quality of yield curve estimation depends on model sensitivity to the market data. For non-sensitive models, such as Nelson-Siegel yield curve model, final effect is insignificant. For more sensitive models, such as bootstrapping, missing data imputation allows to increase the quality of yield curve estimation. However, the result does not depend on the chosen data imputation method. Both simple last observation carried forward method and more advanced EM–algorithm lead to similar final results. Therefore, when estimating yield curves on the illiquid markets with missing market data, we recommend to use either simple non-sensitive to the data parametric models of yield curve or to impute missing data before using more advanced and sensitive yield curve models.
Effect of Underwriter’s Reputation on Performance of small business IPOs
Authors: Siwach P. , Kumar P. R. , Gupta V.
Published: December 2023

The purpose of the study is to determine the impact of the underwriter’s reputation on shaping the short- and long-term IPO success of small businesses. The paper uses IPO data from 2012 to 2020, three reputable proxy and event-time methodologies to analyze the company’s performance through market-adjusted excess returns, cumulative abnormal returns and buy & hold returns. Similarly, to mitigate common predispositions, use the calendar-time methodology, Fama-French three-factor model and Carhart four-factor model with high and low reputational groups. The study revealed a significant positive impact of underwriters’ reputations on first-day returns and long-term performance. Overall, the results indicate that, in the longterm, IPOs of Indian small and medium-sized enterprises are over efficient with regard to reputation signals. On the contrary, the calendar-time method and multifactor model indicate the low long-term IPO effectiveness of the SME. According to the authors’ conclusion, this is the first study to assess the impact of underwriter reputation on business performance using several reputation indicators, the calendar time methodology, and the multi-factor model on the ICP’s Indian IPO platform.
Impact of Institutional Environment on Banks’ Non-Performing Loans: Evidence from BRICS Countries

Published: December 2023

The drivers of non-performing loans (NPL) and the possible effects of the institutional and business environments on the credit risk exposure of banks in the panel of BRICS countries and segregated models are analyzed in this paper. The purpose of the study is to identify the relationship between banking, macroeconomic and institutional factors of non-performing loans of banks at the BRICS level for the period 1996–2020. The panel ARDL approach is used for this purpose. The Panel Granger causality test is applied to verify the hypothesis of the relationship between economic development and NPLs. Panel co-integration tests examine the existence of a long-term link between the same two variables. The results of the study demonstrated that a decrease in the proportion of NPLs results from boosting performance metrics like the Z-score. Because the banking industry has more resources as a result of higher financial development and/or financial intermediation, the amount of NPLs is reduced. Finally, our study demonstrates how important the institutional environment is for raising the quality of bank credit. It was concluded that the low level of NPLs in BRICS countries was largely linked to more effective anti-corruption management, robust regulatory standards, increased application of the rule of law, freedom of speech and accountability.
Colaboração no âmbito educacional

Published: December 2023

O artigo visa esclarecer a dinâmica de colaboração entre os entes federativos na implementação da política de creches, com ênfase nas relações entre estados e municípios. A oferta de vagas de creche é responsabilidade do município, devendo ser executada com a cooperação técnica e financeira de União e estados. A falta de clareza da Constituição Federal de 1988 e normatizações resulta em compreensões divergentes sobre a atuação dos estados, fazendo com que apenas 12 cooperem com os municípios nessa política e que, mesmo nos estados que atuam sistematicamente, como Ceará e São Paulo, as políticas sejam bastante distintas entre si.
