The Covid-19 pandemic that began in the city of Wuhan in China has caused a huge number of deaths worldwide. Countries have introduced spatial restrictions on movement and social distancing in response to the rapid rate of SARS-Cov-2 transmission among its populations. Research originality lies in the taken global perspective revealing indication of significant relationships between changes in mobility and the number of Covid-19 cases. The study uncovers a time offset between the two applied databases, Google Mobility and John Hopkins University, influencing correlations between mobility and pandemic development. Analyses reveals a link between the introduction of lockdown and the number of new Covid-19 cases. Types of mobility with the most significant impact on the development of the pandemic are “retail and recreation areas", "transit stations", "workplaces" "groceries and pharmacies”. The difference in the correlation between the lockdown introduced and the number of SARS-COV-2 cases is 81%, when using a 14-day weighted average compared to the 7-day average. Moreover, the study reveals a strong geographical diversity in human mobility and its impact on the number of new Covid-19 cases.

The outbreak of the COVID-19 pandemic in Wuhan, China, disrupted international trade and changed the global food supply chain. Disruptions affected all food supply chains, including those critical to national security. To the best of our knowledge, this study is the first to reveal the impact of the pandemic on the military food supply chain in Poland. In the analysed single case study, we used process mapping to show the diversity of the types of military food supply chains operating in military units. The attention was focused on the internal and external food supply chains in the context of the disruptions and dysfunctions that appeared in the sphere of management. The contribution of the article is twofold. First, we used a situational crisis management approach to isolate four types of internal military food supply chains. Practical guidance concerns showing actions influencing the modification of system solutions in the military sphere in peacetime in connection with the pandemic. As a member of the North Atlantic Treaty Organization (NATO), Poland applies system solutions similar to those in place in other allied countries. The results of our research can be used as recommendations for solving problems in the military food supply chain in other countries within NATO.

Inventory control is one of the key areas of research in logistics. Using the SCOPUS database, we have processed 9,829 articles on inventory control using triangulation of statistical methods and machine learning. We have proven the usefulness of the proposed statistical method and Graph Attention Network (GAT) architecture for determining trend-setting keywords in inventory control research. We have demonstrated the changes in the research conducted between 1950 and 2021 by presenting the evolution of keywords in articles. A novelty of our research is the applied approach to bibliometric analysis using unsupervised deep learning. It allows to identify the keywords that determined the high citation rate of the article. The theoretical framework for the intellectual structure of research proposed in the studies on inventory control is general and can be applied to any area of knowledge.

Polish border guards can’t stop a few dozen fast-wheeled APCs and IFVs. If such a force would cross through any road at the eastern border of Poland, it would pass almost intact. Afterward, it would be an easy target, but only before it could hide in a dense urban area. Is eastern Poland prepared for such a surprise attack of under a hundred vehicles that could arrive in many city centres within an hour after the border crossing? If a Russian force arrives at even a medium-sized city centre, they could occupy and hold such a position for weeks and use local civilians as human shields. They could force political negotiations holding also precious city infrastructure hostage. Lack of fast and decisive decision-making which is highly likely (because any bombardment will mean a loss of life of civilians) will only make any attempt to regain the city more difficult.
