(Wydawnictwo Uniwersytetu Rzeszowskiego, 2021) Kozicki, Bartosz; Britchenko, Igor; Ovsepyan, Arsen; Grabowska, Sabina
The purpose of the study is to forecast the number of passengers transported by air in the United States for 2021-2022. The forecast is preceded by a multidimensional comparative analysis of the number of passengers transported by air in the United States from 1 January 2019 to 2 November 2021. To achieve this goal, the research data were grouped as dependent variables: years, months-years. The observed similarities, the analysis and evaluation of the literature as well as our own experience made it possible to forecast primary data for the future. The obtained results show a growing trend in the number of passengers transported by air in the United States. The forecast for 3 November 2021 to 31 December 2022 is 837,459, 877 prospective air passengers in the United States. The standard deviation of the obtained forecast was 255,680,3, the arithmetic mean was 1,975,141 passengers, and the median was 1,998,478 passengers. The observed similar trends in the identical months of July-October in 2019 and 2021 as well as the analysis of the literature and the own experience allowed for the selection of a method for the forecasting of the number of passengers transported by air in the United States for the future. The detected regularities as recurring trends in the number of air passengers transported in the United States on a dynamic basis may be used to forecast them for the future.

(Wydawnictwo Uniwersytetu Rzeszowskiego, 2024-03) Kozicki, Bartosz; Sowa, Bogdan; Tomaszewski, Jarosław
The multidimensional comparative analysis of factors influencing the change in the human population in selected European countries in terms of social security in Poland was conducted in the study., the highest population growth between 2013-2022 out of 31 European countries analyzed was recorded in Germany (2 713 378), France (2 271 575) and Sweden (896 433). During that period, a decrease of 408 288 people was recorded in Poland. The main factors influencing changes, especially population declines, include the negative difference between human births and deaths. Another factor was the increase in the arithmetic mean of age of women at the birth of their first child. However, the development of social security in Poland has been influenced by the migration of refugees from Ukraine to Poland since 2022.

(Wydawnictwo Uniwersytetu Rzeszowskiego, 2023-03) Latosiewicz, Dariusz; Kozicki, Bartosz; Magniszewski, Marek; Tołwiński, Maciej
The article presents research on the impact of the financial crisis between 2007-2009 and the COVID-19 pandemic in 2020 on the freight and passenger rail transport sector. Multidimensional comparative analyses were used in the study. The data obtained for the research were grouped. They were, then, compiled on categorized line and bar charts. The research shows that during the financial crisis between 2007-2009, a decrease in the number of transported goods by 48 488 thousand tons was observed. During the COVID-19 pandemic between 2019 and 2020, a decrease in the number of goods was also visible - by 15,363 tones. However, when considering the number of passengers transported, during the financial crisis between 2007-2009 in Poland there was an increase by 1,928 people and in the period of impact of COVID-19 in 2020 compared to 2019 a decrease by 130,270 passengers. When examining the rail passenger transport sector in Poland, a decrease in the number of employees by 385 was observed in the years 2003-2021. During the financial crisis between 2007-2009, the number of employees increased by 5,745 people, while during the COVID-19 pandemic in 2020, compared to 2019, it decreased by 109. In the case of the rail passenger transport sector in Poland, the number of employees oscillated around the arithmetic mean of 23,914 employees. Between 2003-2007, a downward trend can be observed, followed by a visible increase in 2008 and a downward trend in subsequent years.
