ABSTRACT

Coronavirus disease 2019 (COVID-19) has seen a crucial outburst for both females and males worldwide. Automatic lung infection detection from medical imaging modalities provides high potential for increasing the treatment for patients to tackle COVID-19 disease. COVID-19 detection from lung CT images is a rapid way of diagnosing patients. However, identifying the occurrence of infectious tissues and segmenting this from CT images implies several challenges. Therefore, efficient techniques termed as Remora Namib Beetle Optimization_ Deep Quantum Neural Network (RNBO_DQNN) and RNBO_Deep Neuro Fuzzy Network (RNBO_DNFN) are introduced for the identification as well as classification of COVID-19 lung infection. Here, the pre-processing of lung CT images is performed utilizing an adaptive Wiener filter, whereas lung lobe segmentation is performed employing the Pyramid Scene Parsing Network (PSP-Net). Afterwards, feature extraction is carried out wherein features are extracted for the classification phase. In the first level of classification, DQNN is utilized, tuned by RNBO. Furthermore, RNBO is designed by merging the Remora Optimization Algorithm (ROA) and Namib Beetle Optimization (NBO). If a classified output is COVID-19, then the second-level classification is executed using DNFN for further classification. Additionally, DNFN is also trained by employing the newly proposed RNBO. Furthermore, the devised RNBO_DNFN achieved maximum testing accuracy, with TNR and TPR obtaining values of 89.4%, 89.5% and 87.5%.

ABSTRACT

The research is to see how E-banking affects the performance of a bank. As a measure of the electronic method of transactions, we used credit cards, debit cards, National Electronic Fund Transfer (NEFT), Real Time Gross Settlement (RTGS), and Point of Sale (POS), while Return on Assets (ROA) was used as a metric of profitability. The research focuses on India's top ten public sector banks, as determined by market capitalization. The findings reveal that digital payment instruments considerably influence return on assets, indicating that internet banking might help banks increase their profitability. Furthermore, the study shows that electronic banking has a significant favorable influence on bank profitability. Financial institutions were able to reduce their banking expenses after the advent of e-banking services. Furthermore, technical progress in the banking industry provides additional potential for banks to improve their interaction with customers, easier access to banking facilities by clients, and banks' market reach with e-banking.

ABSTRACT

This study examines the determinants of management confidence level of listed bank on the Indonesian Stock Exchange. The confidence level referred to confidence in deciding the deposit interest rate given to customers. The lower the interest rate compared to the other, the bank's management is more confident. This means that with lower deposit interest, management remains confident that customers remain loyal. This research used Model Panel Data to estimate determinants Banks Management Confidence Level in Indonesia moderated by Bank Scale. Banking ratio and macroeconomic data for period 2017 and 2021 become variable research in this paper. This research found that CAR and NPL has positive and significant effect on IETDR at level of Significant of 5%. Inflation and COVID have negative and significant effect on IETDR. Bank Scale or Bank Book as moderating variable could strength to IETDR for CAR and NPL.

ABSTRACT

This study aims to examine the influence of intellectual capital on the financial performance of the telecommunications industry during the COVID-19 pandemic. The population includes the telecommunications companies listed on the Indonesia Stock Exchange in 2019-2020. Moreover, the intellectual capital performance was measured by the value-added intellectual capital coefficient (VAICTM) approach while the model was developed and hypotheses tested using linear regression analysis. The results showed that intellectual capital has a positive and significant effect on return on assets and return on equity but has no influence on earning per share. Recommendations are later made for researchers and practitioners. Copyright © 2023 Inderscience Enterprises Ltd.

ABSTRACT

Purpose: The seepage of companies' capital accommodated by weak country-level institutions is inconducive to building sustainable businesses. Companies' performance on environmental, social and governance (ESG) issues is still a challenging question. This study aims to test the predictability of ESG on the performance of the health-care industry from a global perspective, while accounting for the country disclosure and director liability indices and performing robustness tests. Design/methodology/approach: This study relies on panel data of 912 companies operating in 38 different countries for 2012–2020. This study controls for firm-level variables (leverage, size and loss), macroeconomic variables (COVID, gross domestic product and inflation) and institutional variables. Findings: Findings indicate that countries with different levels of disclosure exhibit different patterns. Distinctly, the environmental pillar has a concave impact on return on assets, and the role of the disclosure index greatly manifests with the environmental pillar. Practical implications: This study ponders the impact of country disclosure on sustainability practices from a global health-care perspective. Originality/value: This paper is original, as it addresses the relationship between ESG performance and financial performance while accounting for the impact of institutional factors such as the business disclosure and director liability indices. © 2022, Emerald Publishing Limited.

ABSTRACT

The COVID-19 pandemic and the implementation of Large-Scale Social Restrictions that occurred in Indonesia resulted in an economic slowdown. Then the problem that is present in the banking sector is the difficulty of debtors in fulfilling their financing obligations. The purpose of this study is to analyze the differences in the performance of the National Sharia BPR before the covid 19 pandemic and during the covid 19 pandemic for the period June 2018 -September 2021. In this study, performance was measured by the asset return ratio (ROA), capital adequacy ratio (CAR), ratio of nonperforming financing (NPF), operating expenses to operating income (BOPO), and the ratio of financing to deposit (FDR). The research is included in quantitative research with a comparative type. The data used is secondary data in the form of the financial statements of the National Sharia BPR obtained from www.ojk.co.id. Data analysis in this study used paired sample t-test analysis with the help of the SPSS version 25 program. The results showed that only CAR and NPF had significant differences before and during the COVID19 pandemic. While ROA, BOPO, and FDR had no significant differences. before and during the covid 19 pandemic.

ABSTRACT

In the context of the economic uncertainty generated at the national level and caused not only by the COVID-19 pandemic, for a healthy evolution of business relations in the competitive environment, for resilience and survival in this context of the pandemic and efforts to counteract possible financial losses, optimal risk management plays a key role in the banking system to avoid excessive exposure with a negative impact on financial performance. The present research aimed to provide an analysis of the potential relationship between the competition presented on the example of the Romanian banking market ( before the onset of the COVID-19 pandemic and after its start), risk management in terms of risk-weighted assets (credit risk, market risk and operational risk), on one hand, and the profitability of the banking system measured by the ROA (return on assets) indicator, on the other. In order to test the formulated hypotheses, the authors used a predominantly quantitative research methodology based on a statistically deductive analysis with a series of testing objectives and potential cause- effect links. The results of this study indicate, before the onset of the COVID-19 pandemic, the existence of a significant intensity correlation between the banks' exposure to the total risk ( RWA) (risk-weighted assets) and the market share (as dependent variables) and the banking performance indicator (ROA) (as an independent variable) and, after the onset of the COVID 19 pandemic, banks' exposure to the credit risk, together with the position on the banking market.

ABSTRACT

An uphill question of whether Environmental, Social, and Governance (ESG) directly impact firms' financial performance (FP) continues to vacillate between two opponent streams. In the present study, we argue that COVID-19 is an extreme event where the effect of ESG sharply manifests. We rely on cross-sectional data in the context of G20 countries for the year 2020. To avoid biased results due to governments support, we integrate four novel metrics provided by the Oxford Coronavirus Government Response Tracker (OxCGRT). We run sequential regressions (OLS; and quartiles to account for the Ingrained Income Bias (IIB) and ESG scores). We also perform robustness tests and account for the interaction between ESG and cash level. Our models were subsequently replicated for each ESG pillar. Findings indicate that ESG is beneficial during COVID-19, but the reward appears to be closely tied up to specific aspects of ESG, income level, and firm-specific variables. Results contribute to the burgeoning literature on ESG during COVID-19 by reflecting on firms' key attributes and the preponderance of government support.

ABSTRACT

The study aims to determine the impact of Capital Adequacy Ratio, Credit Losses Ratio and Efficiency Ratio on the two significant profitability ratios, namely Return on Assets (ROA) and Return on Equity (ROE), during the pandemic. Panel Data Regression is used to model the effects of Capital Adequacy, Credit Losses and Efficiency Ratio on Return on Assets and Return on Equity of Indian banks. A suitable model has been developed by analyzing the results of the Hausman test and the p-values. It has been found that Capital Adequacy Ratio (CAR) with coefficient value of –0.664, CET1 with coefficient value of 1.83 and efficiency ratio with coefficient value of 1.825 have significantly affected the return on assets as their p-values are less than 0.05. However, the accepted relationship between CAR and ROA, efficiency ratio and ROA were inverse, but their coefficients were significant. The provision for credit losses (PCL) was not affecting the ROA significantly during the pandemic and hence was not considered while framing the model. Again, the dependent variable is the return on equity, except CAR. Other ratios, i.e., CET1, efficiency ratio, and PCL ratio have unacceptable correlations and are even non-significant as their p-values are less than 0.05. © The author(s) 2022.

ABSTRACT

The condition of manufacturing companies that experienced a bad impact due to the weak value of operational activities resulted in a decrease in company profits so that the impact on the portion of corporate social responsibility disclosure was reduced. The Covid-19 pandemic has caused several manufacturing companies to be unable to generate profits that have been determined at the General Meeting of Shareholders (GMS) so that the return on investment is lower. This study aims to examine in depth the systematic risk that will affect stock returns in changing the relationship between investor sentiment, trading activity, market factors and stock return responses during the Covid 19 Pandemic. The population used in this study are manufacturing companies listed on the Indonesia Stock Exchange. as many as 169 companies. Of the 169 companies listed on the Indonesia Stock Exchange, there were 39 companies that were delisted during 2020 and 45 companies that did not have complete data on the required research variables, so the number of sample companies used was 85 companies. The data analysis technique uses Structural Equation Modeling (SEM) analysis with PLS smart software. The results of the study show that CSR has a negative effect on ROA with a significance level of 0.000. CSR has a positive effect on stock returns with a significance level of 0.000. ROA has a positive effect on Stock Return with a significance level of 0.000.

ABSTRACT

Companies in the energy sector, due to their important role in the economy and the specificity of energy sources, are exposed to many types of risk, ranging from the risk associated with the company’s operations and the global economic and political situation in the world. Energy companies are usually large capital companies whose shares are listed on the stock market. The mentioned risk factors may shape the risk level of these companies. The study aims to examine the relationship between market and accounting risk measures for Polish energy companies listed on the Warsaw Stock Exchange. This paper uses market and accounting betas in the conventional and downside approach. In addition to market measures of total risk, it also examines the variability of ROA for energy companies. The study of the relationship between market risk measures and accounting risk measures was based on Pearson’s correlation coefficient, standard linear regression, and quantile regression. The relationship between market and accounting measures of total and systematic risk was identified. Moreover, quantile regressions revealed that the slope for accounting variables varies across the quantiles. Our research shows that for energy companies not listed on the capital markets, for which no market risk measures can be derived, accounting betas and downside accounting can be useful tools in risk analysis. The contribution of the article to the risk analysis of energy companies is the use of unpopular accounting beta factors and a new modification of these coefficients for downside risk.

ABSTRACT

This study discusses the impact of COVID-19 on the biotech industry vs. TSEC Taiwan 50 Components stocks. We found that the price of stocks in the biotech sector in Taiwan increased due to the COVID-19 pandemic. The financial leverage ratio did not significantly affect the stock price of biotech companies during the COVID-19 pandemic. The number of confirmed diagnosed cases in Taiwan decreases the stock price of biotech companies, for high ROA. In contrast, the number of confirmed diagnosed cases in Taiwan increases the stock price of biotech companies, for high ROE. Investors have more confidence in the biotech firms with shareholder returns during the COVID-19 pandemic.
