    Purpose: The theoretical purpose of this study was to determine the essence of smart specialisation in local administrative units, together with the identification of its impact on the level of entrepreneurship and socio-economic development of spatial units. The empirical purpose was to indicate the relationship between the level of development of intelligent organisations (IO) in counties and the degree of entrepreneurship intensity. Design/Methodology/Approach: The paper uses the method of literature studies, the standardised sums method, the weighted correlation method and cartographic analysis. Findings: Intelligent specialisation in a local administrative unit (LAU) can contribute to the development of entrepreneurship and accelerate the socio-economic development of the area. Investment attractiveness is more important for stimulating the development of entrepreneurship than intelligent organisation in local administrative units at the county level in Poland. Practical Implications: Results of the research can be used by local administrative units to shape the development strategy of an intelligent organization as well as of a smart specialisation. They can provide valuable practical guidance and synergies. Originality/Value: The paper identifies key features of the smart specialization strategy. The paper defines the intelligent organizations development level index in local administrative units of the county level in Poland in 2018 based on a set of variables. A method of constructing typologies of local administrative units is based on indices determining the level of intelligent organization, investment attractiveness and entrepreneurship. The methodological concept can be used to assess the level of development of IOs in taxonomic units of different levels in different countries.peer-reviewe

    Updates in Management of SARS-CoV-2 Infection

    Severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) has spread worldwide from the beginning of 2020. The infection is mostly asymptomatic but some patients may develop COVID‑19 (coronavirus disease 2019) with a severe or critical course leading to pneumonia, acute respiratory distress syndrome, and multiorgan failure. Apart from the virus‑related damage of the lungs, pathomechanism of the disease seems to be linked to thromboembolism and inflammation accompanied by overproduction of proinflammatory cytokines, termed a cytokine storm, responsible for multiorgan damage and death. Since the development of a new therapeutic molecule, dedicated strictly to a particular virus is time‑consuming, physicians and scientists have started to test and repurpose old medications. Unfortunately, after one year of pandemics, there is still a lack of optimal therapy and no clear indicators of recovery. A major issue is also insufficient knowledge on predictors of the severe or deadly course of the disease, which could also help to switch from one therapeutic option to another. Due to many gaps still existing in the management of COVID-19, there is a need for the accumulation of new data particularly from real-world experience, which could be applicable to practice guidelines. The objective of this special issue of the Journal of Clinical Medicine is to provide an update on the mangement for the diagnostic workup and pharmacotherapy of SARS‑CoV‑2 infection

    Radicalism and Terrorism in the 21st Century

    Get PDF
    This book addresses the issues of radicalism and terrorism, which are of exceptional importance and relevance in contemporary society. Each of the two phenomena are analyzed from a multidisciplinary perspective. The book contains articles which explore legal, political, psychological, economic and social aspects of radicalism and terrorism. A portion of the contributions are of a theoretical nature, they constitute an attempt at constructing analytical frameworks for studies on the two phenomena. There are also studies of particular cases, such as radicalism in Poland and in Spain, as well as within the European Union as a whole. This collective work is a response to the need for analyses of two issues which are increasingly responsible for determining the level of security which characterizes the contemporary world
