War is theoretically subject to the laws of armed conflict but, in practice, it brings in its wake war crimes, crimes against humanity, genocide, and the crime of aggression. The parties to an armed conflict are unable and/or unwilling to hold the perpetrators of these crimes (oftentimes their own citizens) to account. Part of the rationale for establishment of the International Criminal Court was to offer a way forward in this regard. Yet the suspected war criminal – even the political leader of the aggressor state – must be apprehended and brought to The Hague so that he may face the Court. This is no easy task, thwarted by a variety of formal, factual, and political obstacles; all too often, the idea of a supranational justice system presided over by the International Criminal Court proves illusory, if not fictitious. In this article, these points are discussed in reference to the crimes being committed against the Ukrainian population by the Russian aggressors.

The study focuses on the generalization of the methodology of transport planning with the use of the LOGFAS IT system. The main activities that must be performed in order to plan the transport correctly in the IT software were presented. This process requires a lot of experience and work in many program modules and the implementation of a lot of different information without which planning is impossible.

The article presents a multidimensional comparative analysis of the number of passengers transported by air in Europe between 2019-2022 in terms of economic security. Data for the study was taken from Eurostat and categorized line and bar graphs were used. The conducted research shows that in 2021, in each of the considered European countries, an average of 138% of the number of passengers of 2020 were transported by air. In 2022, an increase to 230% of the number of passengers of 2021 was observed. The forecasting of the number of passengers conducted by air transport for 2023 in 29 European countries under consideration was made. A naive method was used for the forecasting. In 2023, the largest number of passengers will be transported in Spain, followed by Germany in the second place and France as third. The sum of the forecast of the number of passengers transported for 2023 in 29 European countries under consideration will equal 1 401 839 218 people and will be higher than in 2022 by 296 222 604 people.

The article presents a multidimensional comparative analysis of the impact of crude oil and liquefied petroleum gasses (LPG) prices on the housing price index in 28 European countries. Research shows that the COVID-19 pandemic and the attack of Russia on Ukraine have led to similar large fluctuations in crude oil and LPG prices. This, in turn, contributed to an increase in inflation and house price indices in the 28 analyzed European countries. Such an increase was driven by higher total construction costs, including higher prices for materials, energy and charges for building services. Housing prices in respective European countries vary. The study examines the dynamics of their changes and compares them with the use of ranking.

A multidimensional analysis of one of main macroeconomic indicators, specifically, unemployment, in the United States was conducted and presented in the article. The research covered several groups of dependent variables, such as: the number of unemployed people in total in the United States monthly, along with unemployment rates, CPI indices, and unemployment in respective US states. The evaluation of the conducted research is that from January 2020 to October 2023 there had been a visible decrease in unemployment rates, and their level is similar to the values recorded from January 2018 to January 2020, which clearly proves that the crisis caused by the COVID-19 pandemic has been averted. The analysis method was used in the study, i.e. distribution of variables into prime factors and comparison dynamically in order to detect the regularities occurring in them.

The study presents a multidimensional comparative analysis of two dependent variables: the number of passengers transported by air in 28 European countries and the price of one barrel of crude oil in dollars. The conducted analysis shows that in the historical data concerning the identical periods (months) in both tested series, dependencies can be found. This allowed for the construction of a zero-one multiple regression model in order to confirm the impact of the number of passengers travelling by air on the price of one barrel of crude oil and describe this phenomenon with an analytical function.

The multidimensional comparative analyzes of transportation of people by rail were used in the article. The time series was analyzed and evaluated in order to detect the following phenomena: trend, seasonality and random factor. The initial time series was divided into parts in order to remove data that, due to the impact of a random phenomenon such as the COVID-19 pandemic, lost trends visible in the past (from January 2012 to December 2019). The Winters’ exponential smoothing method was used for the forecasting. The obtained forecast for 2024 is 390 380 000 passengers transported by rail in Poland. The mean absolute forecast error is 2,18.

The article presents a multidimensional comparative analysis of the number of employees in the enterprise sector in Poland on a quarterly basis between 2010-2021 and new and withdrawn jobs dynamically in terms of economic security. The volume of employment and salary for work in Poland in the enterprise sector by type of activity was analyzed. The last stage of the research was the analysis and evaluation of the time series of salaries in Poland and its forecasting for the future.

The study attempts to forecast the total costs of a company in Poland. The first stage of the research was analyzing and evaluating the time series of total costs. It detected: trends, seasonality and a random factor. This became a premise for the application of two methods for forecasting: Holt-Winters’ multiplicative and additive. The research shows that the Holt-Winters’ multiplicative model proved to be better in forecasting total costs in the research subject. The forecasted total costs from July to December 2022 will reach PLN 45 395 685, while from January to December 2023, their value will amount to PLN 85 948 927.

Human resource management is an essential element in shaping a safe working environment. How the company manages human resources will determine the level of achieved goals. The study analyses the quality of occupational security of people deprived of their liberty in Poland. The obtained findings can be instrumental for constructing better-tackled policies.
