The article consists of three integral parts. It characterises the essence of the functioning of creative clusters, the concept of open innovation and crowdsourcing strategic dimension. Considerations presented in the article are focused on the importance of crowdsourcing in the development of creative clusters. The problem of using crowdsourcing to solve complex problems can be evaluated with multiple levels and multiple perspectives. The authors emphasise that this model of communication between cluster members and external stakeholders allows the use of internal and external resources of creativity in the process of co-creation of positive changes, including innovations (e.g. entrepreneurial solutions to local and global new challenges). They indicate that the implementation of the crowdsourcing in creative clusters can have both, a commercial dimension, where new business projects are the result of the transfer of knowledge, and a non-commercial one, for instance, a wider use of this concept in the development of creative spaces. It was stressed that innovativeness is one of the attributes of entrepreneurial orientation of clusters. Moreover, the key barriers to development of open innovation within a cluster environment are different problems related to intellectual property. The article is based on theoretical research (literature review) and on desk research. Considerations contained herein are conceptual and provide a starting point for further research on the impact of crowdsourcing on the open innovation process within creative clusters.

Non-steroidal anti-inflammatory drugs (NSAID) are class of drugs with antipyretic, analgesic and antiinflammatory properties. They have also exhibited anti-tumor activity. Even though the mode of their antiinflammatory activity action is well understood, they exhibit significant adverse effects. Metal complexesation with NSAID may be a promising option for side effects reduction. The novel silver complexes with commonly used non-steroidal anti-inflammatory drugs: ibuprofen, naproxen, mefenamic acid and ketoprofen, were synthesized and characterized by elemental analysis, IR- spectroscopy and thermal decomposition techniques. Coordination of ligands to the silver ions was confirmed by IR spectroscopy. IR data clearly indicate that NSAID anions are bonded in a monodentate mode. The thermal behavior of complexes was studied by TG, DTG and DTA methods in air. Upon heating all compounds decomposed progressively to silver oxide, which was the final product of pyrolysis.

The economic costs of electricity generation in Poland differ significantly from its accounting costs. Overt and covert forms of public support and taxation obscure the picture of the relationship between the public sector and the energy industry, and give rise to speculations whether one generation technology is privileged over another, i.e. used more often than other technologies with lower economic costs. The analysis presented in this article shows that there are significant differences in terms of impact of individual electricity generation technologies on public finances in Poland.
