Concept of species in bears (Ursidae): practical, historical, and theoretical viewpoint
Wagner, Jan ; Fejfar, Oldřich (advisor) ; Sabol, Martin (referee) ; Musil, Rudolf (referee)
The present thesis surveys topic of taxonomic diversity and phylogeny of bears (Mammalia, Ursidae) and aspects of its contextual setting under effects of changing conceptual and methodological viewpoints. This problem is studied from several perspectives. The historical perspective is represented by a critical overview of the history of specific and infraspecific classification of bears with special respect to mutual influences of this classification and theoretical concepts of species accepted in particular periods. The perspective of material approach is exemplified by a material-based study of taxonomical and phyletic status of selected Pliocene to Middle Pleistocene ursine taxa. Along with deconstruction of some traditional hypotheses this produced a model explaining species diversification in ursine bears and its discussion in terms of factual relevance of included background concepts. In the pre-evolutionary period the bear species were usually understood broadly, as incipient immanent entities, yet exhibiting obvious certain infraspecific variability. This was established using definitions of varieties (mostly not identifiable with present subspecies or infraspecific taxa) considered as unstable modes of particular species. Although, in the post-Darwinian period, the concept and taxonomic...

Possibilities of using social networks to promote RunCzech running league
Fejfar, Ondřej ; Molnár, Zdeněk (advisor) ; Černý, Jan (referee)
This thesis deals with the issue of social networks in terms of business support and their use for commercial purposes. Based on long-term statistics from the most widely used social networks in the Czech Republic, this thesis describes the main principles of using these social networks as a means of increasing profit or turnover. Particular attention is paid to Facebook, the leading social network in the online world. This study concerns the combination of marketing and the IT world, which nowadays has a key role in the sale of products and services. This study should show the importance of the combination of these two worlds. The practical part of the study is the analysis of the communication of the RunCzech Running League (formerly the Prague International Marathon), including a detailed analysis of one their competitors on the market. For the analysis appropriate metrics were selected, which were measured using special tools. The conclusion includes a comprehensive evaluation and presents suggestions for more effective future communication of the RunCzech running leagues in the field of social networking.
