Abstract Even if the people density, habits and displacements probably represent the most important causes of the SARS-Cov-2 virus propagation, the role of the atmospheric aerosol needs to be investigated. Therefore, we aimed to study if the aerosol properties related to the different sources and meteorological conditions we can observe in urbanized areas can have an influence on in the atmospheric transport of the SARS-Cov-2 virus. This paper focuses on the lockdown period to reduce the differences in the social behavior. As an example, we investigated the contamination cases during March 2020 in two specific French areas located in both continental and coastal areas with regard to the meteorological conditions and the corresponding aerosol properties. To this end, we used both the optical depth (AOD) and the Angstrom exponent provided by the AERONET network. The results show that the analysis of aerosol ground-based data can be of interest to assess a virus survey. In particular, our data show that moderate to strong onshore winds occurring in coastal regions, which allow large sea-spray production episodes, deal with smaller COVID-19 contamination rates. This is probably due to the fact that the coagulation of SARS-Cov-2 particles with hygroscopic salty sea-spray aerosols would tend to inhibit its viral infectivity via possible reaction with NaCl, especially in high relative humidity environments. In contrast, out results confirm that the atmospheric transport of the SARS-Cov-2 can be favored by its coagulation with anthropogenic aerosols, which protects the virus particle from ambient humidity and preserves its infectivity.Capsule: Our results suggest that maritime air-masses limit the SARS-Cov-2 impact via the role of the sea-spray.

Abstract Background: Even if the people density, habits and displacements probably represent the most important causes of the SARS-Cov-2 virus propagation, the role of the atmospheric aerosol needs to be investigated. Therefore, we aimed to study if the aerosol properties related to the different sources and meteorological conditions we can observe in urbanized areas can have an influence on in the atmospheric transport of the SARS-Cov-2 virus. This study focuses on the lockdown period to reduce the differences in the social behavior.Methods: We have investigated the contamination cases of four specific geographic areas, two in France and two in Italy, located in both continental and coastal areas with regard to the meteorological conditions and the corresponding air mass properties. To this end, we used a survey of meteorological conditions and aerosol properties via both the optical depth (AOD) and Angstrom exponent retrievals for these locations during March 2020. Results: The results show that the analysis of aerosol ground-based data can be of interest to assess a virus survey. In particular, our data show that moderate to strong onshore winds occurring in coastal regions, which allow large sea-spray production episodes deal with smaller COVID-19 contamination rates. One possible reason is the coagulation of SARS-Cov-2 particles with hygroscopic salty sea-spray aerosols that would tend to inhibit its viral infectivity in environments with high relative humidity via possible reaction with NaCl. Conclusions: In this paper, we hypothesize that marine atmosphere conditions tend to decrease virus infectivity. In contrast, the atmospheric transport of the SARS-Cov-2 can be favored by its coagulation with anthropogenic aerosols, which protects the virus particle from ambient humidity and preserves its infectivity.

Aerosol Properties

Human behaviors probably represent the most important causes of the SARS-Cov-2 virus propagation. However, the role of virus transport by aerosols—and therefore the influence of atmospheric conditions (temperature, humidity, type and concentration of aerosols)—on the spread of the epidemic remains an open and still debated question. This work aims to study whether or not the meteorological conditions related to the different aerosol properties in continental and coastal urbanized areas might influence the atmospheric transport of the SARS-Cov-2 virus. Our analysis focuses on the lockdown period to reduce the differences in the social behavior and highlight those of the weather conditions. As an example, we investigated the contamination cases during March 2020 in two specific French areas located in both continental and coastal areas with regard to the meteorological conditions and the corresponding aerosol properties, the optical depth (AOD) and the Angstrom exponent provided by the AERONET network. The results show that the analysis of aerosol ground-based data can be of interest to assess a virus survey. We found that moderate to strong onshore winds occurring in coastal regions and inducing humid environment and large sea-spray production episodes coincides with smaller COVID-19 contamination rates. We assume that the coagulation of SARS-Cov-2 viral particles with hygroscopic salty sea-spray aerosols might tend to inhibit its viral infectivity via possible reaction with NaCl, especially in high relative humidity environments typical of maritime sites.

Methodological Aspects

The article deals with methodological aspects of the development of ecological culture of schoolchildren in a multicultural educational environment. The authors identify two acute problems in modern society – multiculturalism and ecology. The Russian Federation is a multicultural country. Multicultural education is aimed at preserving the diversity of Russian society, carries the potential and tool for protecting ethnic and national communities in a multi-ethnic Russia, promotes the integration of all territorial-economic, political and national-cultural communities into a single Russian nation, allows a person to adapt to a multicultural world, helps a person understand himself and the people around him and promote the social role of a cultural person in society. The authors consider the relationship between multiculturalism and ethnopedagogy, identify the main pedagogical approaches and principles of development of multicultural education. The article notes the importance of integration of two significant areas in education and in the world - ethnology and ecology. Together they make an ethno-cultural module and an eco-cultural module which form the values for the society sustainable development. The possibility of using the technology of project activity through the implementation of ethno-ecological projects of students is considered. The authors note that ethnoecological projects on the dominant activity of students can be of different directions: research, educational, creative or practical ones. The most effective way to work on projects is through the implementation of a system of eco-oriented multicultural project weeks. Authors pay an important attention to the projects aimed at studying the ethnoecological traditions of the native land, the peculiarities of its geography, climate, natural landscape, flora and fauna, reflected in folklore, folk crafts, cults, rituals, holidays, legends, myths, etc.

The present paper aims to explain crime by investigating various theoretical approaches and to show that from the classic era to the recent postmodern theories, a slow but steady cycle of discourse concerning crime has been occurring. In the classic times, the criminal is assumed to be a sane person with sound will who commits crime with an individualistic choice and due to incorrect decisions; In the positivism approach, the theorists' concern is directed at recognizing criminals and clarifying more fundamental biological aspects and psychological performance and they seek to explain the phenomenon of crime by dividing the people of the society into normal and abnormal people; In the modern theories the social factors causing the appearance of crime are at the focal point while critical theories greatly emphasize on the role of the society in the criminal phenomenon and its definition, finally postmodern theories consider crime totally as constructed by mindset, language and power and question its existential reality.

New Perspective

AbstractNW by Zadie Smith opens with a multicultural and multiracial scene and revolves around the crises in the lives of four people with longstanding connection to Northwest London. The Northwest London in NW is a besieged city, and the people therein could not see any possibility of getting out because the gate has been latched with the concept of social class. In NW, the social class is materialized as space, economic position and race. Geographically NW features the main areas of London, and considers the role of that city in shaping the consciousness of the major characters, a partly spatial configuring of identity. In addition, the major characters in NW also suffer from occupational exclusion and economic exploitation, which then lead to their lower-class position since social class is constructed in such a way that agents are distributed according to their positions in the statistical distribution based on the economic and cultural capital. Finally the racial discrimination encountered by the characters in NW shows that class relations shape the form that racial oppression takes. The racialization of class issues becomes a politically effective tool for the wealthy to divide and rule the lower classes. In NW, Smith thus has adopted a more political attitude than in her previous books, so the relatively new perspective of her fiction might be the attention she draws to the persistent obstacles to class crossing and the acknowledgment of the rigid lines that still define the social classes.

This chapter analyzes the first wave of the revolution against Hosni Mubarak. Refuting arguments that focus on the role of the social media, or divisions among the elite, and the alleged neutrality of the Egyptian military, the chapter illustrates that it was a revolutionary coalition of the middle and lower classes that created a breaking point for the regime. Key features of this mass mobilization included the refusal of protesters to be cowed by state violence, the creation of “liberated zones” occupied by the people, “popular security” organizations that replaced the repressive security apparatus of the state, and strikes that crippled the economy in the final days of the Mubarak era. Key moments during the 18 days are described with ethnographic detail, including the unfiltered reactions of protesters to the deployment of soldiers on January 28. The revolutionary nature of the uprising is that people demanded more than just the ouster of Mubarak—they wanted to topple “the regime” by naming the names of a slew of Mubarak’s cronies to remove them from power.
