Why do People Share Misinformation during the COVID-19 Pandemic?

The World Health Organization have emphasised that misinformation - spreading rapidly through social media - poses a serious threat to the COVID-19 response. Drawing from theories of health perception and cognitive load, we develop and test a research model hypothesizing why people share unverified COVID-19 information through social media. Our findings suggest a person's trust in online information and perceived information overload are strong predictors of unverified information sharing. Furthermore, these factors, along with a person's perceived COVID-19 severity and vulnerability influence cyberchondria. Females were significantly more likely to suffer from cyberchondria, however, males were more likely to share news without fact checking their source. Our findings suggest that to mitigate the spread of COVID-19 misinformation and cyberchondria, measures should be taken to enhance a healthy skepticism of health news while simultaneously guarding against information overload

A Systematic Review of the Digital Interventions for Fighting COVID-19: The Bangladesh Perspective

The objective of this paper is to synthesize the digital interventions initiatives to fight against COVID-19 in Bangladesh and compare with other countries. In order to obtain our research objective, we conducted a systematic review of the online content. We first reviewed the digital interventions that have been used to fight against COVID-19 across the globe. We then reviewed the initiatives that have been taken place in Bangladesh. Thereafter, we present a comparative analysis between the initiatives taken in Bangladesh and the other countries. Our findings show that while Bangladesh is capable to take benefits of the digital intervention approaches, tighter cooperation between government and private organizations as well as universities would be needed to get the most benefits. Furthermore, the government needs to make sure that the privacy of its citizens are protected

Semi-monthly effect in stock returns: new evidence from Bombay Stock Exchange

Semi-monthly effect is a kind of calendar anomalies which is less explored in the financial literature. The main objective of this paper to investigate the presence of semi-monthly effect in selected sectoral indices of Bombay Stock Exchange (BSE). The study uses the daily stock returns of five sectoral indices viz S&P BSE Auto Index, S&P BSE Bankex, S&P BSE Consumer Durables Index, S&P BSE FMCG Index and S&P BSE Health Care Index for the period of 10 years starting from 1st April 2007 to 31st March 2017. The data were analyzed using two approaches namely calendar days approach and trading days approach. To test the equality of mean returns for the two halves of the month, Mann-Whitney U test is used. The empirical results of the study did not provide any evidence for the presence of semi-monthly effect in the selected sectoral indices. Nevertheless, BSE Auto Index showed significant difference in the mean returns of first half and second half of trading month during the study period

China’s trade in climate smart goods: an analysis of trends and trading patterns

Trade and investment have positive effects on economic growth and development, especially for developing countries, where trade openness could play a crucial role to eliminate poverty. But in the same way trade and investment can also harm the environment by producing GHG, pollutions and other environmental negative externalities. Since economic development, trade and environment are elaborately interconnected, it is indispensable to amalgamate environmentally affiliated issues on the development agenda. With expansion of economic activities and trade on the one hand and consequent threats to the environment on the other, the question of environment-friendly trade has emerged as a serious policy agenda in recent years. In that context, trade in climate smart goods (CSGs) is assumed to play a significant role in promoting sustainable development pathway. Given that China’s global trade is expanding at an unprecedented scale, the present paper is designed to analyze the trends and trading patterns of China’s trade in CSGs with the rest of the world. Based on the collected data covering the period of 1992 to 2016 from UN Comtrade, the analyses indicate that total trade in CSGs by China has been increasing, but its share in total trade volume is still very low. It is understood that China’s exports and imports of CSGs are dominated by a few products, namely photosensitive semiconductor devices (854,140), static converters (850,440), articles of plastic and arts of other material (392,690), photovoltaic system controller (853,710), discharge lamps, fluorescent (853,931), parts of electric motors, generators, generating sets and rotary converters (850,300), machine and mechanical appliance (847,989), other lead-acid accumulators (850,720), prism, mirrors and other optical elements unmounted (900,190), cooking appliances and plate warmers (732,111), gears and gearing, other than toothed wheels (848,340), other machinery, plant and equipment (841,989), filtering or purifying machinery and apparatus for gases (842,139), etc. While the major trading partners of China for CSGs are the USA, Japan, India, Malaysia, Germany, Korea Republic, Singapore, Thailand, Vietnam, the Netherlands, Hong Kong, Russia, Brazil, Australia, Pakistan, Israel, among others

Evaluating Web and Mobile User Interfaces With Semiotics: An Empirical Study

Computer interface signs, such as navigational links, thumbnails, small images, command buttons, symbols, icons, etc., which serve as communication artifacts between designers/systems and users, constitute an under-researched area. To design and evaluate intuitive interface signs, the Semiotic Interface Sign Design and Evaluation (SIDE) framework was developed. The aim of this study is to test the framework & x2019;s applicability to evaluate web and mobile user interfaces. To that end, two empirical user studies were conducted among a total of 86 practitioners (n1 & x003D; 58, n2 & x003D; 28). The results show that the SIDE framework helps identify unique usability problems, such as the intuitiveness of interface signs in terms of their referential meaning, which would not have been detected with traditional heuristic evaluation methods. The paper increases our understanding of the intuitive nature of interface signs of web and mobile interfaces, and of the practical use of intuitive signs

Financing profitability optimization: case study on sharia business unit of regional development banks in Indonesia

The study aims to examine the financing profitability optimization as recorded by Sharia Business Unit of Regional Development Banks (RDBs) in Indonesia. The profitability measured by Net Operating Margin (NOM) and predicted variables were tested with the ratio of Operational Cost to Operational Income (BOPO), Non-Performing Financing (NPF) and Profit Sharing Financing (PSF). On the basis of the literature review conducted, the study proposed five path coefficients to impact NOM, of which the constructed direct path to NOM was three and two for indirect paths. Time series data used were obtained from annual reports and publication reports. Using Pearson Correlation and Path Analysis, the study has found that BOPO, PSF, and NPF contributed to impact to NOM directly, and PSF impacted NOM indirectly through BOPO. Interestingly, PSF recorded a negative impact on NOM, suggesting inefficiency matters faced by SBU of RDBs not contributed from PSF. Another interesting finding, NPF was found insignificant to BOPO, indicating loan default is not a major matter for inefficiency issue, but could be a tight financing policy
