Indium tin oxide (ITO) is a material belonging to the group of transparent conductive oxides, which are widely used in many fields of technology including optoelectronics and photovoltaics. However, the properties of ITO thin films depend on many factors. Therefore, the aim of the study was thorough investigation of the properties of sputtered ITO thin films of various thicknesses.

ITO coatings were deposited by magnetron sputtering in pure argon atmosphere using ceramic ITO target. Various deposition times resulted in obtaining thin films with different thickness, which had significant influence on the optoelectronic properties of deposited coatings. In this work the results of investigation of structural, surface, optical and electrical properties were presented.

Increase of the coating thickness caused change of the microstructure from amorphous to nanocrystalline and occurrence of grains with a size of 40 to 60 nm on their surface. Moreover, the fundamental absorption edge was red-shifted, whereas the average transmission in the visible wavelength range remained similar. Increase of the thickness caused considerable decrease of the sheet resistance and resistivity. It was found that even thin films with a thickness of 10 nm had antistatic properties.

The novelty and originality of presented work consists in, among other, determination of antistatic properties of ITO thin films with various sheet resistances that are in the range typical for dielectric and semiconducting material. To date, there are no reports on such investigations in the literature. Reported findings might be very helpful in the case of, for example, construction of transparent antireflective and antistatic multilayers.

The purpose of this paper is to examine the impact of the COVID-19 pandemic on the traditional hotel industry and Airbnb in nine major European cities. The author examines differences between the two business models and analyses various strategies of Airbnb hosts to cope with the crisis.

A detailed empirical analysis is presented based on data from STR and Inside Airbnb for the period January 2018–September 2020. To assess the impact of the pandemic on the hotel industry, year-to-year changes in various performance metrics are presented. The author also investigates the impact of the pandemic on Airbnb prices with panel data regression analysis. Using text-mining methods, signs for new use-cases are explored, including renting flats for home-office or quarantine.

The results support that Airbnb supply is more flexible. While hotel supply quickly returned to a level close to 2019, the average number of Airbnb listings was lower by more than 15%. Furthermore, the price analysis showed that Airbnb rates decreased more moderately than hotel prices. These findings suggest that a significant share of hosts pivoted from short-term accommodation provision and used their property differently, e.g. rented on a long-term basis. The analysis of listing characteristics revealed that the role of longer stays increased; however, the results do not support a shift towards advertising listings for home-office or quarantine purposes.

This paper presents the impact of the pandemic on the hospitality sector in a wide sample of European cities, explores the adjustment of hotels and Airbnb and provides new evidence on the differences between the business models.

The paper surveys selected standpoints in the Polish humanities that are visibly critical toward neoliberal assumptions and claims of economics. The resources used in the text are: Andrzej Szahaj’s philosophical postulates and assertions; Tadeusz Kowalik’s view; criticism and postulates of social economics articulated by the quarterly magazine Nowy Obywatel (The New Citizen). The purpose of this paper is to construct a possibly cohesive picture of this type of criticism by indicating important similarities between the approaches mentioned above, its strongest arguments, philosophical premises and political inclinations.

A conceptual synthesis and interpretation of theoretical standpoints and its philosophical premises, a comparative analysis of the text/content of the magazine (The New Citizen).

Each of the three standpoints discussed in the paper proves to be an interesting example of social economics. It is also symptomatic that they share a similar, critical attitude toward the way in which the transformation of the Polish economy from a socialist to a capitalist system had been carried out. The transformation is thereby interpreted as a process that is not accomplished at all from the point of view of the ideals of social justice and integrity.

The popularization of Polish normative views of economics taking into account the problem of social justice, and the possible transformation of the way in which economic problems are publicly understood in Poland.

The discussion of non-standard interpretations of Polish transformation and its effects that undermine and challenge neoliberal ideology in economics.
