“…Another community to the top right of the network is formed at the central keyword measures, which is heavily linked to the cluster's response, travel-related, considerations, and social-distancing, among others. The interpretation here is that the researchers focused their search on spread due to travel-related cases and assessed the imposed measures on social-distancing protocols and their respective public response ( Gómez-Ríos, Ramirez-Malule, & Ramirez-Malule, 2020 ; Mogaji, 2020 ). In addition to that, a community at the center of the network represented by the keywords travel, US, travel-restrictions, infections shows that further considerable research is done on spreading due to traveling ( Niehus et al, 2020 ).…”

“…Barro et al [ 34 ] found that the coronavirus pandemic and Spanish flu increase mortality and economic contraction, mostly low real returns on stocks and short-term government bills. Gómez-Ríos et al [ 35 ] concluded that the coronavirus pandemic was mainly out of control due to the imported number of cases from uncontrolled air travellers. Social distancing avoids massive gatherings and restricts international travelling to maintain the decreasing trend in the infections trend.…”

The service industry provides distributive services, producer services, personal services, and social services. These services largely breakdowns due to restrictions on border movements, confined travel and transportation services, a decline in international tourists’ visitation, nationwide lockdowns, and maintaining social distancing in the population. Although these measures are highly needed to contain coronavirus, it decreases economic and financial activities in a country, which requires smart solutions to globally subsidize the services sector. The study used different COVID-19 measures, and its resulting impact on the services industry by using world aggregated data from 1975 through 2020. The study benefited from the Keynesian theory of aggregate demand that remains provided a solution to minimize economic shocks through stringent or liberalizing economic policies. The COVID-19 pandemic is more severe than the financial shocks of 2018 that affected almost all sectors of the globalized world, particularly the services sector, which has been severally affected by COVID-19; it is a high time to revisit economic policies to control pandemic recession. The study used quantiles regression and innovation accounting matrix to obtain ex-ante and ex-post analysis. The quantile regression estimates show that causes of death by communicable diseases, including COVID-19, mainly decline the share of services value added to the global GDP at different quantiles distribution. In contrast, word-of-mouth helps to prevent it from the transmission channel of coronavirus plague through information sharing among the general masses. The control of food prices and managing physical distancing reduces suspected coronavirus cases; however, it negatively affects the services sector’s value share. The smart lockdown and sound economic activities do not decrease coronavirus cases, while they support increasing the percentage of the services sector to the global GDP. The innovation accounting matrix suggested that smart lockdown, managing physical distancing, effective price control, and sound financial activities will help to reduce coronavirus cases that will further translate into increased services value-added for the next ten years. The social distancing will exert a more considerable variance error shock to the services industry, which indicates the viability of these measures to contained novel coronavirus over a time horizon. The study used the number of proxies to the COVID-19 measures on the service sector that can be continued with real-time variables to obtain more inferences.

“…A broad range of subjects related to social distancing have been addressed in the scientific literature such as: political, economic, social and religious challenges ( Yezli and Khan, 2020 ), adolescents' motivations to engage in social distancing ( Oosterhoff et al, 2020 ), sexual activity ( Jacob et al, 2020 ), the relation with telework implementation ( Kawashima et al, 2020 ), the impact on crime ( Mohler et al, 2020 ), personal wellbeing ( Nyenhuis et al, 2020 ), social and ethical basis for social distancing ( Lewnard and Lo, 2020 ), etc., while in the area of travel and human mobility the primary research areas focused on: travel behavior ( De Vos, 2020 ), uncontrolled travelers effect on the spread of the coronavirus ( Gómez-Ríos et al, 2020 ), airline employment evolution ( Sobieralski, 2020 ), estimating and projecting air passenger traffic ( Iacus et al, 2020 ), and comparing classical airplane boarding methods while considering social distancing rules ( Cotfas et al, 2020 ).…”

This paper addresses the airplane passengers’ seat assignment problem while practicing social distancing among passengers. We proposed a mixed integer programming model to assign passengers to seats on an airplane in a manner that will respect two types of social distancing. One type of social distancing refers to passengers being seated far enough away from each other. The metric for this type of social distancing is how many passengers are seated so close to each other as to increase the risk of infection. The other type of social distancing refers to the distance between seat assignments and the aisle. That distance influences the health risk involved in passengers and crew members walking down the aisle. Corresponding metrics for both health risks are included in the objective function. To conduct simulation experiments, we define different scenarios distinguishing between the relative level of significance of each type of social distancing. The results suggest the seating assignments that best serve the intention of the scenarios. We also reformulate the initial model to determine seat assignments that maximize the number of passengers boarding an airplane while practicing social distancing among passengers. In the last part of this study, we compare the proposed scenarios with the recommended middle-seat blocking policy presently used by some airlines to keep social distancing among passengers. The results show that the proposed scenarios can provide social distancing among seated passengers similar to the middle-seat blocking policy, while reducing the number of passengers seated close to the aisle of an airplane.
