Role of microbes in the decomposition in headwater streams.
Kociánová, Petra ; Kopalová, Kateřina (advisor) ; Tátosová, Jolana (referee)
The decomposition of organic matter in headwater streams is a key process in stream ecology and an important component of the global carbon cycle. Decomposition rates depend on both abiotic and biotic factors, the former including temperature, discharge, and nutrient chemistry, and the latter including stream community structure and activity, trophic interactions, biodiversity, and productivity. Of the stream community, microbial decomposers play a particularly important role in decomposition by chemically degrading compounds and transferring nutrients and energy to higher trophic levels. These processes are prone to change due to current and future global warming which will affect both decomposer communities and associated decomposition rates. This thesis provides a short overview of the main factors that control stream decomposition rates, including biological factors like microbial activity, abiotic factors such as water temperature and nutrient availability, and how these factors may be altered in the future under a warmer climate. Specifically, I predict that climate change will increase microbial activity and decomposition in headwater streams due to increased water temperatures, changes in surrounding vegetation, and shifts in the hydrological regime due to global warming. .

Innovation Culture in small and medium-sized Enterprises: the Importance of Soft Factors in early Stages of the Innovation Process
Kociánová, Petra ; Jaklová, Martina L. (advisor) ; Ulsamer, Frank (referee)
The study at hand investigates innovation systems at small and medium enterprises (SMEs) focusing on innovation culture, organization and company goals at the early stages of innovation process. Past research studies suggest the early stages of innovation process are critical for the overall innovation ability, however, there is a lack of literature on the specifics of innovation systems at SMEs. Case studies of 3 companies provide an overview of characteristics of innovation systems at a typical SME as well as a solid basis for drawing business implications relevant for establishing or improving its innovation system. Furthermore, the findings reveal that people management at the early stages of innovation process is missing, and that a foreign subsidiary of an international SME is relevant for an effective corporate innovation process. Implications for further research on the topic are also discussed.

Postavení cestovního ruchu v ekonomice Číny
Kociánová, Petra ; Kašpar, Václav (advisor) ; Vošta, Milan (referee)
Bakalářská práce analyzuje postavení aktivního a pasivního cestovního ruchu v ekonomice Číny a jeho dopady na platební bilanci. Podrobně jsou popsány vlivy dynamického rozvoje cestovního ruchu na rozvoj dopravní, technické a urbanistické infrastruktury. Důraz je kladen na potenciál odvětví cestovního ruchu v Číně v nadcházejících letech.
