Rozwój miast, a zwłaszcza rozwój metropolitalny powoduje powstawanie barier mobilności. W szczególności konieczne jest równoważenie mobilności z wykorzystaniem niskoemisyjnych podsystemów transportowych. Równoważenie mobilności wymaga podejścia systemowego i stosowania różnych instrumentów. Jednym z nich jest cena usług publicznego transportu zbiorowego, w tym dyskutowana żywo propozycja wprowadzania bezpłatnego transportu zbiorowego w miastach. W Polsce zamiar wprowadzania bezpłatnego transportu zbiorowego zgłaszają coraz szerzej władze kolejnych miast uzasadniając to chęcią ograniczenia ruchu samochodów i tym samym zrównoważenia mobilności. Jednak skutki takich decyzji są wielokierunkowe i długookresowe, tymczasem argumenty uzasadniające efektywność bezpłatnego transportu miejskiego w równoważeniu mobilności nie znajdują jednoznacznego potwierdzenia w badaniach naukowych.

The development of the modern economy depends on the efficiency of complex global logistics chains. Logistics employs modern management and telematic technologies, whereas knowledge management is the basis for growth of efficiency and effectiveness of logistics chains. A particular role is played by the universities which educate the future workforce for the Transport-Forwarding-Logistics (TFL) sector. Based on the data from the POLON system, it may be concluded that logistics education is common, especially at the economic and technical universities. According to the Polish statistical data, the graduates find jobs very quickly, whereas their remunerations are higher than the average. The activity of universities in respect of research and education for the purpose of logistics is a factor in the growth of competitiveness of this economy sector. However, it is necessary to improve the study programs, using knowledge of practitioners and results of scientific research.

Preventing sudden cardiac death (SCD) in athletes is a primary duty of sports cardiologists. Current recommendations for detecting high-risk cardiovascular conditions (hr-CVCs) are history and physical examination (H&P)-based. We discuss the effectiveness of H&P-based screening versus more-modern and accurate methods. In this position paper, we review current authoritative statements and suggest a novel alternative: screening MRI (s-MRI), supported by evidence from a preliminary population-based study (completed in 2018), and a prospective, controlled study in military recruits (in development). We present: 1. Literature-Based Comparisons (for diagnosing hr-CVCs): Two recent studies using traditional methods to identify hr-CVCs in >3,000 young athletes are compared with our s-MRI-based study of 5,169 adolescents. 2. Critical Review of Previous Results: The reported incidence of SCD in athletes is presently based on retrospective, observational, and incomplete studies. H&P's screening value seems minimal for structural heart disease, versus echocardiography (which improves diagnosis for high-risk cardiomyopathies) and s-MRI (which also identifies high-risk coronary artery anomalies). Electrocardiography is valuable in screening for potentially high-risk electrophysiological anomalies. 3. Proposed Project : We propose a prospective, controlled study (2 comparable large cohorts: one historical, one prospective) to compare: (1) diagnostic accuracy and resulting mortality-prevention performance of traditional screening methods versus questionnaire/electrocardiography/s-MRI, during 2-month periods of intense, structured exercise (in military recruits, in advanced state of preparation); (2) global costs and cost/efficiency between these two methods. This study should contribute significantly toward a comprehensive understanding of the incidence and causes of exercise-related mortality (including establishing a definition of hr-CVCs) while aiming to reduce mortality.
