Identification of potentially suitable habitats for occurrence of European Ground Squirrel (Spermophilus citellus) using remote sensing
Kadeřábková, Tereza ; Kupková, Lucie (advisor) ; Hais, Martin (referee)
The aim of the thesis was to evaluate the possibilities of remote sensing (RS) data with different spatial resolution (UAV data with 5cm resolution, RapidEye satellite data with 5m resolution and Sentinel-2A data with 10m resolution) and of remote sensing methods (unsupervised and supervised classifications, vegetation indices NDVI and TVI) to identify potentially suitable habitats for European ground squirrel. The analyses were first carried out in Velké Pavlovice small area of interest and consequently in a broader area of interest comprised of five regions of Moravia and Slovakia. Data form mapping of biotopes and squirrels' burrows collected within a project "Sysli pro krajinu, krajina pro sysly" (European ground squirrels for landscape, landscape for European ground squirrels) were also used for the analyses. Remote sensing methods were first tested in Velké Pavlovice area using RapidEye data. The method providing the best results in the detection of European ground squirrel burrows was then used for a burrows detection in the broader area of interest (five regions) using Sentinel-2A data. The accuracy of results was defined as a proportion of the burrows detected by the resulting layer derived from RS data to the overall number of burrows mapped in the field. Best results were obtained for...

Advertising impact of influencers as perceived by the young online users
Kadeřábková, Tereza ; Supa, Markéta (advisor) ; Reifová, Irena (referee)
This work titled Advertising impact of influencers as perceived by the young online users defines the term influencer in its theoretical part, offering several perspectives through which this phenomen can be viewed. For example, the number of followers on influencers' profiles, the interaction between these two sides, or the characteristic features of influential figures, such as their behaviour on the Internet. Furthermore, this work deals with influencer marketing, some types of collaboration between influencers and companies within social media, and the issue of tagging the sponsored commercial content. Also, one of the chapters summarizes some of the findings from several relevant studies, creating an initial insight into the topic. The research part of this work explores the issue as perceived by the young online users, using the research sample comprising 179 respondents in the range of 16-26 years old. The data collected through the electronic standardized questionnaire revealed, for example, that respondents require tagging sponsored posts on influencers' profiles, even though they trust these commercial posts less. Also, the pattern of behaviour hinting some verifying information before immediate tasting influencers' recommendations was indicated. The analyzed answers also point to the...

Adolescent's relation to traditional TV brodcasting in the Internet era
Kadeřábková, Tereza ; Zezulková, Markéta (advisor) ; Lütke Notarp, Ulrike (referee)
The work titled Adolescents' relation to traditional TV broadcasting in the Internet era deals in its first chapter of the theoretical part with the origin and changes of traditional TV broadcasting in our country from the beginning to the present. It creates the historical context of the issue discussed in the following chapters; so it describes what changes TV has gone through in its functioning, social status and role. The second chapter serves as an insight into the adolescents' relation to TV broadcasting, TV content and selected media in an era when the Internet has an increasing potential to take over the role of traditional media. Thematic research and studies conducted in the past are used for the description. In the practical part of the work the questionnaire survey focusing on young people aged 15-18 is used. The aim of quantitative research is to find out the respondents' relation to traditional TV broadcasting and some television content, and also marginally includes an influence of selected media on respondents' TV viewing. The sample is composed of 96 respondents meeting the required age range. For example, it has been found that most respondents are watching traditional TV broadcasting for 1-2 hours a day, but the time spent on this activity differs depending on whether it is a...
