Dynamic connectedness among climate change index, green financial assets and renewable energy markets: Novel evidence from sustainable development perspective

This paper investigates the connectedness among the climate change index, green financial assets, renewable energy markets, and geopolitical risk index from June 1, 2012 to June 13, 2022, using Quantile Vector Autoregressive (QVAR) and wavelet coherence (WC). The Total connectedness index (TCI) varies as long as the highest TCI originates in the upper quantile. We also note that the higher TCI decreases after the second wave of COVID19 and increases during the first 100 days of the Russia-Ukraine conflict. Moreover, the results show that Geopolitical risk (GPR) is a net transmitter of the climate change index during the Russian invasion of Ukraine. The green bond and clean energy markets are negatively connected to the GPR at extreme 10 th and 90 th quantiles. The wavelet coherence confirms the QVAR results that the climate change market can be a safe haven against GPR during the Russian invasion. The climate change index, green financial assets, and clean energy are strong influencers in the financial markets and are vital to international peace, reducing geopolitical risk. The study reports a few novel conclusions and implications from a sustainable development perspective.

Social Media Technologies Used for Education: An Empirical Study on TAM Model During the COVID-19 Pandemic

The study's major goal was to figure out what factors impact university students' behavior and intentions to use social media to boost their academic performance during the COVID-19 Pandemic. Given the context-dependent nature of online learning, the Technology Acceptance Model (TAM) was adopted and supplemented with components largely relevant to harnessing social media for collaborative learning and engagement. Collaborative learning, student participation, and a social media mindset are just a few of the new features. The enlarged model was validated using empirical data from an online survey questionnaire filled by a sample of 409 Saudi Arabia higher education students, which assesses students' social media usage intentions and academic performance during the COVID-19 Pandemic. AMOS-SEM was used to analyze the model's various assumptions (Analysis of Moment Structures- Structural Equation Modeling). The findings revealed that: (1) utilizing social media for collaborative learning and student engagement has a direct positive impact on perceived usefulness, ease of use, and enjoyment;(2) perceived usefulness, ease of use, and enjoyment has a direct positive impact on attitude to use social media;and (3) the link between TAM characteristics "usefulness, ease of use, and pleasure" and behavior intention to use social media is mediated by attitude to use social media. (4) Students' attitudes and behavior intentions on social media have a direct positive influence on their academic performance during the COVID-19 Pandemic. Academics, higher education institutions, and educational technology application providers will benefit greatly from the conclusions of this study, both theoretically and practically.

The purchasing managers' index as a predictor of the economic situation during COVID-19 and its relevance for decision making

The economic crisis of the coronavirus differs from all previous ones because of its particularities. There is a simultaneous destruction of demand and supply. It is difficult to know the real impact that the COVID-19 crisis has had on international trade, as it is not usually visible in the short term in most data. However, from indicators such as the purchasing managers' index (PMI) we can get to know the extent of the global slowdown that is taking place. This paper tries to determine the information capacity of the PMI and its importance in previous decision making. To this end, we have analysed the correlation between the PMI and GDP in the European Union, one of the areas that is being most affected by the COVID-19. In addition, some of the possible economic measures by public authorities to reduce the impact of the pandemic are analysed. Copyright © 2021 Inderscience Enterprises Ltd.

SITUATION OF EUROPEAN AIRLINES CAUSED BY COVID-19: RESTRICTIONS, GOVERNMENT SUBSIDIES AND FUTURE PROSPECTS

The COVID-19 pandemic has been an unprecedented crisis, severely affecting the economy and many sectors, including the airline industry. This paper reviews this situation to see how airlines have acted since the beginning of COVID-19. The airline industry is dependent on financial support and subsidies to cope with the massive drop in air travel due to the coronavirus. The support received by the major airlines has been examined. In addition, a comparison has been made of all the aviation restrictions that have been implemented by different European governments. Travellers from countries with a higher incidence of cases, or with a growing rate of cases, have the most restrictions on travel to other countries. Furthermore, the strategies and protocols being implemented by certain airlines following the lifting of some of the restrictions on passenger air traffic are analysed. 'Ibis paper will provide an insight into how airlines are coping with this unfavourable environment, as well as some of the future prospects and strategies of the aviation sector.

Cross-cultural impacts of COVID-19 on higher education learning and teaching practices in Spain, Oman, Nigeria and Cambodia: A cross-cultural study

Adapting new learning and teaching practices during COVID-19 pandemic has impacted students' learning in higher education. Using a cross-sectional research methodology, the study attempted to understand the cross-cultural impacts of COVID-19 on higher education students in Cambodia, Nigeria, Oman and Spain to determine the changes that COVID-19 has brought about in higher education students;examine how students' learning behaviour and attitudes have changed during COVID-19;identify the challenges they have experienced;and identify the changes that have taken place in learning and teaching in the selected countries. A total sample of 242 students was randomly selected from four higher education institutions in each of the selected countries. The study provided a cross-cultural understanding of how COVID-19 has affected students' well-being, behaviors and learning. The results show that COVID-19 had adverse effects on the well-being of students in the four countries. Students received inadequate social support and security protection from others and instructors when they needed it. Omani students received less social support compared with the other three countries. COVID-19 had the worse effect on students' employment in the four countries. The effect pressed much concern on Nigerian students who experience a great job loss. Students from the four countries were required to put a lot of effort and energy to fulfil the requirements in the program.

COVID-19 and infodemics: How to solve this problem

COVID-19 has not only caused an unprecedented health crisis;it has also caused an infodemic with the spread of false news. The role of the media is crucial in trying to reduce the spread of these hoaxes. Infodemics can cause citizens and political institutions to make bad decisions. Some of the fake news that authorities are most concerned about are those related to remedies to prevent contagion or cure symptoms, as these deceptions can lead to increased contagion or worsening of the disease by coronavirus. The media can play a positive role during the Covid-19 pandemic by promoting effective strategies to help people prevent the spread of the pandemic. They have the ability to convey a sense of unity by reaching large numbers of people, but can also provide grounds for misinformation and discrimination. This article reviews some of the major hoaxes that have spread during the coronavirus crisis, and provides guidelines for citizens to detect the false information that is being disseminated. In addition, useful recommendations are established for content creators and information disseminators, with the aim of promoting effective and truthful communication during this crisis.
