DIGITAL CAPACITY OF RUSSIAN TOURIST TERRITORIES

Digitalization has affected the economies and the everyday life of the population all around the globe. Industries are going digital with the Industry 4.0 mode changing the conventional practices of doing business. People spend a significant amount of time online shifting their daily routines to electronic format. The wide dissemination and adoption of ICTs place mutual expectations from the population to have competence in using modern digital technologies and from firms and public institutions to provide their services online. Not surprisingly there is a strong digital divide between territories in their digital capacity – the ability of a territory to generate digital content. This study is aimed at evaluating the digital capacity of cities and municipalities in Russia by measuring their digital footprint in the tourism industry. Tourism is found to be an information - intensive economy sector with a large volume of consumer-generated content making it ideal for measuring the digital capacity of territories. The research design is based on geotagged hashtags sourced from Instagram – one of the most popular social networks worldwide. The geographical scope of research covers 205 cities in 10 regions of Russia – Arkhangelsk region (14 municipalities), the Republic of Crimea and Sevastopol (19 municipalities), Kaliningrad region (28 municipalities), Krasnodar region (26 municipalities), Leningrad region (69 municipalities), Murmansk region (16 municipalities), and Rostov region (23 municipalities). All of the regions are located in the European part of the country but differ in environmental, socio-economic, and geopolitical parameters. In order to focus on the tourism sector, the dataset on tourist accommodation establishments and bed places is collected in addition to population statistics. The analyzed data is mapped, and a series of figures present the re search findings. The research results suggest that consumer-generated content with place-related hashtags in Instagram is applicable for tracking the tourism sector development and the tourism-related digital capacity of a territory. However, a number of limitations are identified in using user-generated digital content in social media. This includes overrepresentation of large cities over smaller settlements despite not being the direct location of reference; ‘noisy data’ featuring additional meaningless information due to ambiguous hashtags; an increasing volume of commercial posts from bloggers, self-employed, and business.

Transmission Control of Cross-Regional Heterogeneous Networks for Direct Position Determination

In direct position determination (DPD), a large number of observation data need to be integrated and transmitted, which creates higher requirements for the transmission performance of the network. To alleviate the problem of performance degradation in a large number of data transmissions, this paper proposes a heterogeneous network architecture and transmission control algorithm for cross-regional heterogeneous networks. Through the heterogeneous integration of satellite and multihop networks, a transmission control model suitable for the long delay and high bit error rate environments is established, the congestion window of each stage of network transmission is analyzed, and the efficiency and accuracy of the algorithm are verified by experiments. The results show that a large amount of data can be transmitted in a heterogeneous network. When dealing with direct location, the algorithm can effectively transmit a large number of observation data for cross-regional heterogeneous networks. This simple and applicable transmission control algorithm can improve the satellite link throughput and reduce the download response time compared with the traditional transmission algorithm. These studies provide a reference for a large number of data transmissions in direct position determination.

COVID-19 in New York state: Effects of demographics and air quality on infection and fatality

ABSTRACTThe coronavirus disease 2019 (COVID-19) has had a global impact that has been unevenly distributed amongst and, even within countries. Multiple demographic and environmental factors have been associated with the risk of COVID-19 spread and fatality, including age, gender, ethnicity, poverty, and air quality among others. However, specific contributions of these factors are yet to be understood. Here, we attempted to explain the variability in infection, death, and fatality rates by understanding the contributions of a few selected factors. We compared the incidence of COVID-19 in New York State (NYS) counties during the first wave of infection and analyzed how different demographic and environmental variables associate with the variation observed across the counties. We observed that the two important COVID-19 metrics of infection rates and death rates to be well correlated, and both metrics being highest in counties located near New York City, considered one of the epicenters of the infection in the US. In contrast, disease fatality was found to be highest in a different set of counties despite registering a low infection rate. To investigate this apparent discrepancy, we divided the counties into three clusters based on COVID-19 infection, death rate, or fatality, and compared the differences in the demographic and environmental variables such as ethnicity, age, population density, poverty, temperature, and air quality in each of these clusters. Furthermore, a regression model built on this data reveals PM2.5 and distance from the epicenter are significant risk factors for high infection rate, while disease fatality has a strong association with age and PM2.5. Our results demonstrate, for the NYS, distinct contributions of old age, PM2.5, ethnicity these factors to the overall COVID-19 burden and highlight the detrimental impact of poor air quality. These results could help design and direct location-specific control and mitigation strategies.

Erotic Barbarity: Othon

This chapter introduces the specificities and hallmarks of Straub and Huillet’s films through a close study of their 1969 film Eyes Do Not Want to Close at All Times or Perhaps One Day Rome Will Allow Herself to Choose in Her Turn, adapted from Pierre Corneille’s play Othon: literary works adapted to the letter, their use of cinematic composition and space, and direct location sound. Finally, it introduces the troubadour Arnaut Daniel and his complex, subtle poetic structures, later picked up by Louis Zukofsky, which echo the cinematic structures of Straub and Huillet’s films.

Fractions of heavy metals in the soil of the urban agglomeration with increased traffic

The paper presents the results of research on the content of selected heavy metals (Cu, Pb, Zn, Ni) depending on pH, organic carbon content and soil sorption in the direct location of busy streets around the campus of the Kielce University of Technology. Based on the conducted studies of the sequential fractionation of metals by the BCR method was found that the highest content of nickel fraction FI (exchangeable) was 142.75 mg/kg. However, the total nickel concentration in all research areas exceeded the value specified in the Journal of Laws approx. 2 times. The lowest content from the analyzed metals in the surface layer of soil was found for zinc, the content of which was 1.5% in relation to the standard. The average percentage share of the analyzed metals in the separated fractions, in relation to the total content, was in decreasing series for Ni: FIII > FI> FII> FIV; for Pb: FII > FI > FIV > FIII; for Cu: FII > FI > FIII > FIV and for Zn: FII > FIII > FI > FIV. The studied soils are characterized by a varied granulometric composition of sand fraction, from very thick (1000 μm–2000 μm) to very fine 2 μm–50 μm). Statistical calculations showed that the pH, Corg content and sorptivity of the studied soil correlate with each other.

High-Speed Rail, Corporate Real Estate and Firm Location in the Central Business District: The Results from Two Surveys (2008; 2014) in Reims

The arrival of High Speed Rail (HSR) often gives rise to a development of office and corporate real estate programs around the central station where firms are expected to locate. But the question is to know if HSR is, in itself, a location factor or if it induces an indirect effect by triggering a supply of business real estate, which then explains the location of firms. The aim of this paper is to identify the exact role of HSR in firms’ choice of location, and on real estate supply, at the time of opening of HSR services and during their development.We analyzed the case of Reims, a city served since 2007 by the Eastern Europe High Speed Line. Its district near the central station has been transformed into a so-called business district. Two surveys interviewing firms were conducted in 2008 and 2014 respectively. The results of the first survey clearly show that use of HSR does not directly explain the location, but the image effect it generates real estate investments. Such programs quickly find real estate buyers and tenants, mainly local ones, but less from companies outside the city. The second survey makes it possible to identify whether the dynamics noticed in the short term, where strong expectations existed, are still relevant seven years later. Interviews with developers and investors make it possible to identify the reasons why they have invested in this district. This last survey shows the importance of local developers, local public stakeholders and of land availability, but also that HSR becomes, for some firms, a direct location factor.
