Analysis of Fiscal Policy and Monetary Policy during Covid-19 Crisis---an Australian perspective

The outbreak of new coronavirus pneumonia in 2020 has emerged as a significant global epidemic, representing a profound disaster. All nations encounter a shift towards crisis management frameworks, exhibiting variable levels of success in limiting the spread of the virus and mitigating economic repercussions. This is by far the most far-reaching public health event of the 21st century on a global scale, with immeasurable research significance from immunological, economic, and sociological perspectives. For the continent of Australia, which is alone in the ocean, the Australian community could not carry the blow once the epidemic exploded across the country. So, as early as the 20th of March, Australia quickly declared a "border closure", banning all non-Australian citizens and non-permanent residents from entering the country. Moreover, with regard to the movement of persons, production activities and control of cases and close contacts in the region, each oblast has adopted restrictive measures of varying degrees, depending on the severity and development of the outbreak. The special geographical conditions and the policy of a completely closed borderline allow us to value the effectiveness of the Australian government's and banks' response to the stimulus provided by the COVID-19 policy directly by removing most of the external conditions from the equation.

Integrated management is effective in the prevention and control of COVID-19 in the blood purification center: joint efforts from multiple departments

BackgroundDuring the outbreak of new coronavirus pneumonia, many hospitals in China became the designated hospitals for the treatment of new coronavirus pneumonia. The goal was to develop rapid and effective prevention and control methods for blood purification centers.Research design and methodsThe medical department, hospital department, nursing department, and blood purification center jointly set up a multi-department integrated COVID-19 prevention and control management team to manage the blood purification center. The efforts included the establishment of the continuous renal replacement therapy (CRRT) team for COVID-19, the integrated training and assessment of medical personnel, the integrated education of patients and their families, and the integrated management of the workflow of the hemodialysis room.ResultsNo infected persons, including medical staff, patients, and their families, have been found in the dialysis center. After multi-departmental integrated training, the theoretical performance of medical staff in our dialysis center has increased from 82.36 ± 8.10 to 95.29 ± 4.95 (p < 0.05), and the unqualified rate dropped from 23.21 to 1.78% (p < 0.05). In addition, the three operational skills evaluation scores have also been significantly improved, from 86.00 ± 4.02, 88.01 ± 6.20, 92.01 ± 2.46 to 95.90 ± 0.30, 97.21 ± 0.87, 96.00 ± 1.00 (p < 0.01), and the passing rate from 80.36 to 100% (p < 0.05).ConclusionMedical staff’s knowledge of novel coronavirus pneumonia prevention and control can be improved by multi-sectoral integrated management, and CRRT treatment of COVID-19 patients is effective.

Observation on the Efficacy of Autologous Blood Transfusion Combined with Controlled Hypotension in Patients with Spinal Internal Fixation during the Outbreak of New Coronavirus Pneumonia in Western Guangxi (in Guixi)

Objective: To explore the therapeutic effect of autologous blood reinfusion combined with controlled hypotension in surgical spinal fixation during the outbreak of COVID-19. Methods: 30 patients with spinal internal fixation autologous blood transfusion combined with controlled hypotension were selected as the subjects during the epidemic period from December 2019 to June 2020 in our hospital and during the operation, on the basis of routine blood pressure reduction, the American Haemonetice Corporation autologous blood continuous reinfusion system was used to infuse the blood recovered during the operation to the patient through filtration and other procedures. Results: 30 patients had no complications such as fever and hemolysis; And after the operation, the tube was dialed according to the drainage volume, the cervical thoracic and lumbar brace was customized, and the patient walked on the ground for one week; After no abnormalities, the patient was discharged. Intraoperative comparison of white blood cells (WBC), red blood cells (RBC), red blood cell pressure (HCT), hemoglobin (HGB), and coagulation time (PT) of patients with autologous blood before and after transfusion showed statistically significant differences before and after surgery (P < 0.001). Conclusion: During the new coronavirus pneumonia epidemic, the internal fixation of spinal surgery used a recovery machine to collect intraoperative blood for reinfusion. Intraoperative antihypertensive drugs were used to control blood pressure within a certain safe range. The postoperative clinical observation effect was significant and safe; especially at present the clinical significance during the epidemic was significant.

Relative Performance Concern on DC Pension Plan under Heston Model with Inflation Risk

With the global outbreak of new coronavirus pneumonia, more and more countries have entered the state of sealing off cities. After the epidemic, with the shortage of some materials, the economy is very likely to enter the state of inflation. Thereby, it is necessary and urgent for us to reconsider investment problems involving inflation risk. In this paper, we mainly study the optimal investment strategy of two defined contribution (DC) pension managers with strategy interaction under inflation risk. The traditional portfolio literatures mainly focus on DC pension plan and try to maximize the expected utility of terminal nominal wealth. In this paper, we consider the more complicated situation that pension managers have, both concerns on relative wealth and relative risk aversion. Then, the objective function is constructed to satisfy these two concerns. The dynamic programming principle method is employed to solve the above problems, and a series of analytical solutions to this problem are obtained. Finally, some numerical examples are discussed for the economic implications to support our theoretical results.

Fighting against COVID-19: preparedness and implications on clinical practice in primary care in Shenzhen, China

BackgroundThe new coronavirus pneumonia (NCP) caused by COVID-19 has affected more than 46 million people worldwide. In China, primary care has played a vital role during the COVID-19 outbreak, and it is important to examine the challenges faced by general practitioners (GPs). This study investigated the roles, preparedness and training needs of GPs in China in managing the NCP outbreak. Based on the outcomes of the study, we hope to take lessons and identify how GPs could be supported in delivering their gatekeeping roles and clinical duties in times of infectious disease outbreak.MethodsAn online survey on the official website of Shenzhen Continuing Education Center. It included questions on GPs’ demographics, their awareness of COVID-19 and their preparedness in managing suspected cases of NCP, as well as referrals and their training needs. Conditional multi-variate logistic models were used to investigate the relationships between GPs’ preparedness, situational confidence and anxiety.ResultsGPs’ clinical practice was significantly affected. GPs endeavoured to answer a flood of COVID-19-related enquiries, while undertaking community preventive tasks. In addition to in-person consultations, GP promoted COVID-19 awareness and education through telephone consultations, physical posters and social media. Overall GPs in Shenzhen felt well supported with adequate Personal Protective Equipment (PPE) and resources from secondary care services. Higher levels of self-perceived preparedness (OR = 2.19; 95%CI, 1.04–4.61), lower level of anxiety (OR = 0.56; 95%CI, 0.29–1.09) and fewer perceived family worries (OR = 0.37; 95%CI, 0.12–1.12) were associated with better confidence in coping at work.ConclusionsTraining and supporting GPs while reducing their (and their families’) anxiety increase their confidence in delivering the important roles of gatekeeping in face of major disease outbreaks.

Risk Analysis and Crisis Management of Novel Coronavirus COVID-19

After the outbreak of new coronavirus pneumonia, all regions have responded to take measures. Emergency decision-making plays an important role, directly related to the safety of the people, and more deeply will affect the future of the country. In this paper, we try to use the wisdom of large groups which are distributed in the social network to deal with the relevant indicators of the group big data decision-making model under the maximum likelihood estimation of the complementary judgment matrix, to establish the epidemic risk assessment system of infectious diseases, and to realize the group decision-making and risk analysis based on the big data.
