Analysing company's behaviour and communication on social networks
Němec, Milan ; Molnár, Zdeněk (advisor) ; Jelínek, Ivan (referee)
This thesis focuses on measuring company´s communication and behaviour on social networks. To capture the interaction between the company and its users the thesis uses web analytics tools. Therefore, the main objective of the thesis is analysis of these tools. To achieve this goal, the thesis characterizes social networks and their marketing opportunities for business promotion. Thanks to this, needs of using these tools is identified. The needs are: competitive analysis, optimizing communication, measuring achievement of objectives or detection competitive viral content. Research questions were determined and then analysis tools found answers to research questions. It was found that the tools provide various views of data and create a complete system for measuring and analysing behaviour and communication companies on social networks. The results were validated in a case study focused on the Facebook profile of the University of Economics in Prague. The study analysed the interaction profile of the school and its users and compared with others schools. In the results the analysis tools are validated and it is designed recommendation for improve engagement. This thesis revealed strengths and weaknesses of tools for measuring company´s communication and behaviour on social networks. It was found that these tools have wide range of use. They can be used for understanding the company's profile, its users, for purposes of competitive analysis, monitor corporate goals and optimize communications on social networks.

The Conclusion of a Contract under the United Nations Convention on Contracts for the International Sale of Goods in Comparison with Czech National Legislation
Krčálová, Kristýna ; Boháček, Martin (advisor) ; Levý, Jan (referee)
This Master's thesis focuses on the United Nations Convention on Contracts for the International Sale of Goods (CISG), better known as the Vienna Convention. The main purpose of this thesis is to evaluate conditions for application of this international treaty and to assess the contracting process under the CISG including the similarities and differences with the Czech national legislation. Finally, it seeks an answer to the question, which of these rules (international or national) are more advantageous for a Czech contractual party with respect to concluding a contract. The thesis is divided into five parts. The first one represents an introduction to the CISG, its origin and the Czech Republic's attitude to it. The second part identifies the conditions for application of the CISG and therefore defines a subject and an object of an international contract of sale under the CISG. Both third and fourth parts gradually introduce two phases of the contracting process (offer and acceptance) including the relevant case-law. The last chapter strives to complete the contracting process with an analysis of the exact moment, when a contract is concluded, as well as with an analysis of a potential battle of the forms and its impact on a contract conclusion.

Travel Behaviour of the Prague Suburb Population
Pergl, Ondřej ; Novák, Jakub (advisor) ; Marada, Miroslav (referee)
Travel behavior of Prague suburb population Abstract The hinterland of Prague is formed by the process of suburbanization, which influences the spatial structure of whole region. Changed spatial structure puts greater demand on the mobility of the population. The main aim of this work is the research of travel behavior of the Prague suburb population, who makes his movements primarily by the car. The work focuses on the factors influencing travel behavior, which are discussed in theoretical section. The next section discusses the measures against individual transport. The empirical part presents the results of survey in Prague southeast hinterland. Travel behavior is examined in terms of modal split and trip purpose. Further investagation is focused on citizens' satisfaction with the traffic situation in their municipality and reveals their sensitivity to various measures against car use. Key words: mobility, travel behavior, suburbanization, car use limiting, Prague

Infection risks of nursers at the inpatient wards
KUČÍRKOVÁ, Alena
Theoretical backround Working as a nurse is one the most human jobs, by serving to people, taking care and preserve health of a human, which is considered to be the highest value of human life for centuries. The aim of nurses is to take care of a human, to mitigate his or her symptoms and to comfort the life till its end if there is no possibility for full recovery. While they do previously described most of them are not aware of a need to take into account also their own health and especially protection against all dangerous microbes. In my bachelor thesis I analyse infection diseases sometimes also called occupational infections which are the most dangerous for nurses. All occupational infections are stated here together with their descriptions. In following parts of this thesis there are hygiene requirements on the workspace and finally in the last section hygienic-epidemic actions in a health care system are described. Objectives of this thesis Objective 1 Determine whether nurses comply with preventive actions against risks of infections. Objective 2 Determine whether nurses know risks of infections at patients departments. Objective 3 Determine whether nurses know how to defend their spread. Research questions Research Question 1: How do nurses protect themselves against risks of infections? Research Question 2: What information do nurses have about risks of infections in health care system? Research Question 3: In which way do nurses prevent the spread of infection to a de- partment? Methodology The bachelor thesis presents a qualitative research. Methods and techniques of a data collection, which we used in the work were participant observation and semi-structured interviews. The survey was carried out with 6 respondents in anesthesiology and resuscitation departments, surgical and internal intensive care units and intermediate care unit at Nemocnice České Budějvice a.s. The research method of an active observation was used during the survey. We observed certain facts that were recorded during the observation to a observation sheet (Appendix 4) and then transcribed and analysed. Data were collected using semi-structured interviews. The interview was conducted with the same respondents who were observed and recorded in a written form and then overwritten (Appendix 6). Results The results of the observations in the research study showed that nurses unfortunately do not comply with barrier nursing techniques as much as they should. The only thing that they fully comply with the overall finish, wear prescribed clothing and collection of biological material according to hygienic principles. Worse situation was in the using of protective equipment, disinfection and hand washing and eating food, where it did not comply 100%. In the next part of the research we focused on interviews with the observed respondents, the purpose was to find things that could not be identified by the only observing. The results showed that nurses do not even have much theoretical knowledge as regards to a occupational infection, or an injury treatment procedure when infected by an object. Conclusion The survey showed that while most nurses have a clue about good practices and knowledge of the occupational infections and hygienic-epidemiological measures ,but unfortunately theory is different from practice in which these things too oblivious. It emerged that unfortunately practice is different than the theory that we learn at universities and colleges.

Effect of snowpack on runoff generation during rain on snow event.
Juras, Roman ; Máca, Petr (advisor) ; Ladislav , Ladislav (referee)
During a winter season, when snow covers the watershed, the frequency of rain-on-snow (ROS) events is still raising. ROS can cause severe natural hazards like floods or wet avalanches. Prediction of ROS effects is linked to better understanding of snowpack runoff dynamics and its composition. Deploying rainfall simulation together with hydrological tracers was tested as a convenient tool for this purpose. Overall 18 sprinkling experiments were conducted on snow featuring different initial conditions in mountainous regions over middle and western Europe. Dye tracer brilliant blue (FCF) was used for flow regime determination, because it enables to visualise preferential paths and layers interface. Snowpack runoff composition was assessed by hydrograph separation method, which provided appropriate results with acceptable uncertainty. It was not possible to use concurrently these two techniques because of technical reasons, however it would extend our gained knowledge. Snowmelt water amount in the snowpack runoff was estimated by energy balance (EB) equation, which is very efficient but quality inputs demanding. This was also the reason, why EB was deployed within only single experiment. Timing of snowpack runoff onset decrease mainly with the rain intensity. Initial snowpack properties like bulk density or wetness are less important for time of runoff generation compared to the rain intensity. On the other het when same rain intensity was applied, non-ripe snowpack featuring less bulk density created runoff faster than the ripe snowpack featuring higher bulk density. Snowpack runoff magnitude mainly depends on the snowpack initial saturation. Ripe snowpack with higher saturation enabled to generate higher cumulative runoff where contributed by max 50 %. In contrary, rainwater travelled through the non-ripe snowpack relatively fast and contributed runoff by approx. 80 %. Runoff prediction was tested by deploying Richards equation included in SNOWPACK model. The model was modified using a dual-domain approach to better simulate snowpack runoff under preferential flow conditions. Presented approach demonstrated an improvement in all simulated aspects compared to the more traditional method when only matrix flow is considered.

Arctic tundra dendrochronology
Lehejček, Jiří ; Svoboda, Miroslav (advisor) ; Monika, Monika (referee)
Historically unprecedented environmental change in the Arctic ecosystems is often given into the context of its past and possible future development. In the region where instrumental meteorological observations are scarce archives need to be investigated in order to address this issues. The comprehensive synthesis one of the archives: long-live circumpolar evergreen Juniperus communis L. shrub is presented here. 20 individuals from southwest Greenland were investigated at the cell anatomy level to understand the ecology of the species and unhide its potential for environmental and climate reconstructions. The findings are as follows: i) Stop of exponential cross-sectional conduit-lumen widening with increasing age is in contrast with conduit-lumen nature of trees. This indicates that shrubs do not need to saturate their water and nutrient demands via traits of classical hydraulic conductivity law but rather developed different mechanisms. Extreme weather conditions result in prostrate growth form. However, different weather factors probably influence shrub growth differently: While snow and wind act mechanically (a), temperature influences the form of growth physiologically (b). a) So long as the young shrub stem has high resilience to bend back to an upright position after snow melt and so long as it can withstand the wind during the vegetation season it most likely grows upright and the conduit-lumens widen. b) Temperature, resp. freeze-thaw events are responsible for the shrubs preference of safety (finite size of conduit-lumens) over hydraulic efficiency, thus not allowing for more primary growth. All of these (and other) factors are apparently working together and the transition of vertical to more horizontal growth is gradual. As a consequence, the conduit-lumen sizes may not have to be further increased (due to ecophysiological restrictions possibly also must not) because water is no longer transported against gravity. ii) Observed age/growth trend has to be taken into consideration for further employment of the wood anatomical parameter in paleoenvironmental studies. That is, shrub cell parameters can only be used for this purposes if correctly detrended. This allows for more accurate as well as longer reconstructions because youth trend was often neglected in reconstructions based on shrub annual-rings. iii) The south-western Greenland Ice-Sheet (GrIS) melt rates reconstruction is presented for the whole 20th century. This part of GrIS is considered as the most active. According to the presented reconstruction current GrIS melt rates are not uncommon for the last century being comparable to first decades of 20th century. This finding is particularly important contribution to the debate on Atlantic meridional overturning circulation (AMOC). Too high fresh water inputs into the Northern Atlantic from GrIS melting may slow down or even stop the AMOC which would result in more continental climate in Europe. Presented results indicate that this threshold lies higher than observed current melt rates of GrIS. Fascinating Juniperus comunnis species has shown to be able to address many ecological as well as environmental open questions and due to its longevity and abundant distribution has a great potential to become an important player in the Arctic research.

Predicting asp and pikeperch recruitment in a riverine redervoir.
BLABOLIL, Petr
Recruitment of two species, asp (Leuciscus aspius) and pikeperch (Sander lucioperca), in a riverine reservoir was studied using a novel statistical approach. Both species are piscivorous and are stocked into reservoirs for biomanipulative purposes to reduce planktivore species. Long-term data series were used, but the number of potential predictors was high. Therefore, a novel informative statistical approach based on dimension reduction methods was applied. Quality of outputs was driven by sampling methods. Main factors affecting asp recruitment were zooplankton abundance, predator density and temperature. In terms of pikeperch fry measured with seine and trawls, the number of predators was the only important factor. Gillnets underestimate small fish and the data were unsuitable for statistical modelling.

Café - an architectural phenomena of the First Czechoslovak Republic´s society
PFEFEROVÁ, Dita
This bachelor thesis deals with restored cafés in Brno and Prague that were established in the First Czechoslovak Republic. In the case of Brno´s coffee houses it is mostly emphasized their origin, historical context, history of coffee making and how the coffee houses returned to their former look and function. The author deals with the analysis of coffee houses and the purposes and goals of their restoration. The author focuses on Zeman´s café by the architect Bohuslav Fuchs and it´s replica from 1995 and on ERA coffee house by Josef Kranz. Then the focus is shifted to an elegant coffee house Savoy owned by Jan Nekvapil and designed by Jindřich Kumpošt and to a pastry shop and coffee house Kolbaba designed by Jan Víšek. To compare evolution of the coffee houses in Brno the author chose unique cubist coffee house Grand Café Orient in Prague located in Dům U Černé Matky Boží by the architect Josef Gočár. The thesis summarizes the circumstances of the formation of coffee houses during the First Czechoslovak Republic in Prague and Brno and examines different conditions for its development. It also looks into the circumstances of restoration and today´s activity of these coffee houses and evaluates its success rate.
