The COVID19 pandemic, a unique and devastating respiratory disease outbreak, has affected global populations as the disease spreads rapidly. Recent Deep Learning breakthroughs may improve COVID19 prediction and forecasting as a tool of precise and fast detection, however, current methods are still being examined to achieve higher accuracy and precision. This study analyzed the collection contained 8055 CT image samples, 5427 of which were COVID cases and 2628 non COVID. The 9544 Xray samples included 4044 COVID patients and 5500 non COVID cases. The most accurate models are MobileNet V3 (97.872 percent), DenseNet201 (97.567 percent), and GoogleNet Inception V1 (97.643 percent). High accuracy indicates that these models can make many accurate predictions, as well as others, are also high for MobileNetV3 and DenseNet201. An extensive evaluation using accuracy, precision, and recall allows a comprehensive comparison to improve predictive models by combining loss optimization with scalable batch normalization in this study. Our analysis shows that these tactics improve model performance and resilience for advancing COVID19 prediction and detection and shows how Deep Learning can improve disease handling. The methods we suggest would strengthen healthcare systems, policymakers, and researchers to make educated decisions to reduce COVID19 and other contagious diseases.
Africa was the last region to witness significant spread of the COVID-19. Nonetheless, it was expected that the continent would be hardest hit due to the fragility of its health and social infrastructure as well as the vulnerability of its economies. While the rates of infection and death were initially relatively low and contained economically, the continent was hard hit early on. Cuts in credit and trade services by international banks, along with a decline in export earnings, tourism receipts, and inward remittances, have severely constrained the ability of African countries to finance imports of essential goods and to service maturing debt obligations.
However, Africa has over time created mechanisms and institutions to help cushion its economies from the adverse consequences of global shocks. Among these institutions is Afreximbank, which emerged out of the debt crisis of the 1980s. This paper presents an overview of the Bank’s support to African countries in dealing with two major derivatives of the COVID-19 pandemic: the trade finance challenges resulting from cuts in international financial flows to the continent, and the health consequences of the pandemic.
The coronavirus affects the strongly export-oriented Swiss economy in a situation where political and economic developments are already making the cross-border exchange of goods and services difficult. For this reason, the question arises of how Switzerland can maintain or strengthen its position in global competition in the export business during an unprecedented period of crisis such as the current one.
In order to find an answer to this question, this paper critically examines the existing government support measures for Swiss exporters in times of COVID-19. The fact that Switzerland has so far not taken any specific support measures for exporters raises the actual research question of whether there is a specific necessity and demand for a special export promotion. To answer this research question, various expert opinions are compared and overall conclusions are drawn. By rapidly introducing and adapting the already existing instruments – liquidity assistance and an expansion of short-time work benefits – the federal government was able to ensure the survival of many companies. According to the authors of this paper, this focus of government support in times of crisis is just right for a small national economy in the short term and therefore preferable to a specific support of exporters. Nevertheless, given the high relative importance of foreign trade for Switzerland’s overall economic performance, there can be no recovery of national economy without a recovery of foreign trade.
Supporting the COVID-19 response in Asia and the Pacific—The role of the Asian Development Bank.
(2020)
The COVID-19 pandemic has affected all countries of the Asia Pacific region over the last few months with far reaching economic, health and social consequences. To counter the impact, governments have accelerated their health spending and announced large macroeconomic stabilization and stimulus policy packages. As with past disasters and crises in the region, the Asian Development Bank has reacted with a number of targeted support interventions since the very early stages of the outbreak. In mid- April 2020, the Bank then put forward a comprehensive COVID-19 Response Package totalling $20 billion to support its member countries which rests on four pillars.
The last few months have proven that multilateral development banks like the Asian Development Bank have the ability to respond quickly and to mobilize significant resources for a global emergency like COVID-19. Whilst this financial supported is urgently needed at this point, attention will need to be paid on how debt sustainability for low- and middle-income countries can be ensured in the coming years. Given the unprecedented scale of and uncertainty around the COVID-19 pandemic, it may offer a window of opportunity to redesign the way developmental finance is coordinated and the way it is delivered. This also includes a chance to “build back better” and to focus on a sustainable, resilient and green recovery.
This essay deals with the Spanish economy and especially with the Spanish governmental measures for SME exporters in times of COVID-19. The focus was set on SMEs, as they are an essential part of trade for the government and are particularly affected by the pandemic. Since the financial crisis, the Spanish economy has become highly diversified, with a greater focus on exports. Competitiveness, productivity and efficiency have increased significantly. The Spanish government measures largely affect the areas liquidity and financing, taxes and protection of the employment. One of the most important measures is the 100-billion-euro credit line and the policies on unemployment. The Spanish government is dependent on further aid packages and is criticized for the measures.
The COVID-19 pandemic has led to an economic downturn in the Slovak Republic. To bridge corporate liquidity problems the Slovakian Government has introduced several support measures. The investigation discusses the effectiveness of the measures imposed. Based on theoretical foundations, the research question is empirically examined by using a qualitative expert survey. As the automotive industry plays a leading role in Slovakia, the research conducted is oriented towards the financing phases, a typical automotive exporter is undergoing. As a result of the research, bridging loans and government grants were identified as the most important measures. Additionally, tendencies towards political recommendations for action were identified. The research explored, that the Slovakian Government should focus on meeting the short-term liquidity needs, boosting exports and promoting innovation as well as considering a support package for the automotive industry.
Background: Many countries have restricted public life in order to contain the spread of the novel coronavirus (SARS-CoV2). As a side effect of related measures, physical activity (PA) levels may have decreased.
Objective: We aimed (1) to quantify changes in PA and (2) to identify variables potentially predicting PA reductions.
Methods: A systematic review with random-effects multilevel meta-analysis was performed, pooling the standardized mean differences in PA measures before and during public life restrictions.
Results: A total of 173 trials with moderate methodological quality (modified Downs and Black checklist) were identified. Compared to pre-pandemic, total PA (SMD − 0.65, 95% CI − 1.10 to − 0.21) and walking (SMD − 0.52, 95% CI − 0.29 to − 0.76) decreased while sedentary behavior increased (SMD 0.91, 95% CI: 0.17 to 1.65). Reductions in PA affected all intensities (light: SMD − 0.35, 95% CI − 0.09 to − 0.61, p = .013; moderate: SMD − 0.33, 95% CI − 0.02 to − 0.6; vigorous: SMD − 0.33, − 0.08 to − 0.58, 95% CI − 0.08 to − 0.58) to a similar degree. Moderator analyses revealed no influence of variables such as sex, age, body mass index, or health status. However, the only continent without a PA reduction was Australia and cross-sectional trials yielded higher effect sizes (p < .05).
Conclusion: Public life restrictions associated with the COVID-19 pandemic resulted in moderate reductions in PA levels and large increases in sedentary behavior. Health professionals and policy makers should therefore join forces to develop strategies counteracting the adverse effects of inactivity.
The aim of this essay is to analyse and evaluate the Italian government measures for exporters in response to COVID-19. The unexpected, rapid and hardly predictable consequences of the pandemic paralyzed the entire globe. For a long time, Italy was the epicentre of the virus, which caused severe damage in the Italian export economy dropping temporarily more than 40%. The Italian government reacted exemplary fast and took multiple countermeasures of high extent especially through the Italian export credit agency SACE. On the one hand, the internationally compared broad structure of SACE was a huge advantage, which allowed to release quickly numerous measures. On the other hand, there is room for improvement regarding the accessibility of measure-related information, which has been partially only available in Italian. Furthermore, there is a remarkable risk resulting from the combination of the high monetary effort to enable the numerous measures, the difficult financial situation of the Italian government and the unpredictability of the COVID-19 consequences.
The aim of this essay is to point out the challenges and opportunities of government export credits and insurance in Europe. The Covid-19 pandemic confronted the entire world with new challenges. This also applied to the export financing and insurance market. Furthermore, there are also challenges that play a major role for ECAs regardless of the pandemic. However, the risks are also offset by opportunities that may enable European export credit agencies to prevail against international competition.
The focus of this essay is on the export credit agencies from Finland (Finnvera), Sweden (EKN) and Portugal (COSEC). As part of the European Union (EU) and the Organisation for Economic Co-operation and Development (OECD) the three ECAs share many fundamental similarities but in some points they may also distinguish from each other.
