The new coronavirus (COVID-19) is caused by the acute respiratory syndrome 2. The disease was first diagnosed in December 2019 in Hubei Province, Wuhan City, China. On March 11, the World Health Organization declared the virus an epidemic. Until Mid-February, 2021, about 112 million people worldwide have been infected with the virus, of which about 2.500.000 people have lost their lives, according to the latest global statistics from the Worldometer database. The economic shock of the coronavirus outbreak has also led to negative economic impacts, including declining sales of many related businesses. In this paper, the effects of coronavirus on the Iranian economy are examined with a systems dynamics approach. First, the relationships of important variables affecting GDP in SPSS software are obtained and then the data is analyzed using Vensim software. In the following, by analyzing the sensitivity and providing recommendations, the impact of managerial insights to control the conditions of this new crisis will be examined. The results show that the correct use of the mask and the observance of social distance as well as air flow in spaces and avoidance of closed spaces have a significant effect on reducing the spread of this disease and reducing mortality.
The work considers current methodological issues of innovative potential of a small enterprise organized based on a Russian University. The paper contains an analysis of approaches to the concept of "innovative potential", "innovative potential of a small innovative enterprise organized on the basis of a University". The article developed and proposed the author's model, which includes 12 blocks and a scheme for defining the concept of "innovative potential" of the company. In it, taking into account our suggestions, the points of view to its definition were generalized, and a new block was added to the scheme, that will allow small enterprises to develop dynamically in the field of innovation based on higher educational institutions.
The results of the authors' research in the direction of innovative potential of small innovative enterprises organized on the basis of the University may be of interest to other universities as a learning experience, as well as Russian and foreign organizations.
The COVID-19 pandemic has plunged the world into a health and economic crisis never seen before since the Spanish flu pandemic in 1918. The closure of schools and universities, the banning of rallies, and other social distancing in countries have been done to disrupt the transmission of the virus. Governments have planned to reduce restrictions on corona management by implementing vaccination programs. This research aims to better understand the Coronavirus disease’s behavior, identify the prevalent factors, and adopt effective policies to control the pandemic. This study examines the different scenarios of releasing the constraints and returning to normal conditions before Corona to analyze the results of different scenarios to prevent the occurrence of subsequent peaks. The system dynamics approach is an effective means of studying COVID-19’s behavioral characteristics. The factors that affect Coronavirus disease outbreak and control by expanding the basic SEIR model, interventions, and policies, such as vaccination, were investigated in this research. Based on the obtained results, the most critical factor in reducing the prevalence of the disease is reducing the behavioral risks of people and increasing the vaccination process. Observance of hygienic principles leads to disruption of the transmission chain, and vaccination increases the immunity of individuals against the acute type of infection. In addition, the closure of businesses and educational centers, along with government support for incomes, effectively controls and reduces the pandemic, which requires cooperation between the people and the government. In a situation where a new type of corona has spread, if the implementation of the policy of reducing restrictions and reopening schools and universities is done without planning, it will cause a lot of people to suffer.
