Perception of climate change impacts and adaptive capacity in organic agriculture
Říhová, Jana ; Vačkářová, Davina Elena (advisor) ; Pražan, Jaroslav (referee)
This thesis deals with the perception of climate change issue and adaptive capacity of organic farming systems in the Czech Republic. The aim of this thesis it to investigate organic farmers' attitudes toward climate change and their willingness to adopt adaptation practices. The method used in this thesis is based on questionnaires that were distributed among organic farmers in the period of January-March 2015; 52 questionnaires were subsequently analysed. The results indicate that the majority of organic farmers surveyed believed that the global climate change is occurring, expected negative climate change effects and observed higher frequency of extreme weather events. Most of the respondents also acknowledge the importance of adaptation practices and their own responsibility in adaptation. The statistical analysis revealed that both the belief about climate change and perception of associated threats may serve as predictors of the willingness to implement adaptation measures.

The impact of dividend policy on firm value
Říhová, Jana ; Dědek, Oldřich (advisor) ; Janda, Karel (referee)
This thesis is focused on the dividend policy in the Czech Republic. We describe the basic about dividends as types of dividends, process of declaration and payments, dividend-paying methods, determinants which can influence the dividends and so on. The main part is devoted to the issue of dividend policy in the Czech Republic and its impact on the firm value. We use the event studies, based on observing the abnormal returns to shareholders around the record date. Then we apply regression of abnormal returns on relevant explanatory variables. And we also make an analysis of some of explanatory variables, as volume and dividend yield. Finally, we also shortly mention the share repurchase, the alternative to the dividend payout.

Legionella Becoming a Mutualist: Adaptive Processes Shaping the Genome of Symbiont in the Louse Polyplax serrata
ŘÍHOVÁ, Jana
Genomic modifications coupled with the first known transition of a Legionella bacterium to symbiosis with insects (louse Polyplax serrata). Apart from characteristics typical for other obligatory symbionts in insect (genome reduction), the main innovation of the genome consists in horizontal acquisition of complete biotin operon. Comparative genomic analysis with free living legionellae and other symbiotic bacteria demonstrates convergent evolution of several phylogenetically unrelated louse symbionts.

Evoluce genomu bakteriálních symbiontů vši \kur{Polyplax serrata} (Phthiraptera, Anoplura)
ŘÍHOVÁ, Jana
Blood-sucking louse Polyplax serrata harbor two phylogenetically distinct symbiotic bacteria from the orders Legionellales (Gammaproteobacteria) and Neisseriales (Betaproteobacteria). Based on rigorous phylogenetic analyses, the first bacteria was confirmed as member of genus Legionella, and the name Candidatus Legionella polyplacis, sp. n. was proposed. Vertical transgeneration transmission was proved by visualisation of the symbiont in host tissues. Improved genome of latter symbiont is considerably larger and possesses more metabolic functions. In the genome, I found horizontally transferred operon, which encode synthesis of enzymes involved in urea cleavage.

Kateřina Hradecká of Montfort (1556-1631)
ŘÍHOVÁ, Jana
The presented diploma thesis is dealing with the life of Katerina Hradecká of Montfort, noble foreigner, married to Adam II. of Hradec. The author is using older as well as more recent literature, written, tangible and iconographic sources to analyze, based on historical-anthropological methods, transformation of the inner world of the noblewoman. She is firstly introduced as a maid of honor in the hofstadt of archduchess Maria of Bavaria in Graz. Author also looks into her marriage to Adam II. of Hradec, investigating it within political and religious context of that period, as it was associated with the connections of the lords of Hradec to the House of Habsburg. Author also pays attention to the noblewoman as a wife, a mother, a Jesuit confidant, a widow and a strict catholic, that had a substantial influence on the social life of Hradec and its surroundings due to her religious views. Author does not omit the tangible cultural aspects connected with the activities of Katerina Hradecka of Montfort and her impact on the ecclesiastical and secular architecture in Jindřichův Hradec.

Work – life balance of students
Fesslová, Tereza Anežka ; Legnerová, Kateřina (advisor) ; Říhová, Jana (referee)
This bachelor thesis is focused on the importance of work-life balance, which means balance between work and life. The aim of this thesis is to find out current status of satisfaction with work-life balance for students of universities. In the theoretical part is explained the concept of work-life balance and another concepts related to this topic. The focus is drawn on four individual parts of human life, where people must be able to allocate their time. The practical part is devoted to characteristics of current students in general. Then a research is conducted on survey. The respondents are the current students of universities in Czech republic. Based on the research an evaluation of results is find out and a solution is proposed in order to further adjust the conditions for improvement of work, life and study balance for these students.

Long-term population trends of birds in North America and Europe: a metaanalysis of existing studies
Říhová, Jana ; Reif, Jiří (advisor) ; Voříšek, Petr (referee)
Since the beginning of the last century there have been significant changes in the environment, farming and the landscape structure. Because birds are one of the longest- studied groups of organisms and are considered to be good indicators of environmental quality, it is advisable to relate environmental changes to changes in bird abundance. Understanding these relationships enables better and more accurate formulation of conservation plans and priorities, and therefore a large number of studies were dedicated to them. Although these studies achieved great progress in the knowledge of the most important factors that affect bird populations, their findings remained somewhat incomplete and fragmentary due to their limited temporal and/or spatial coverage. Therefore, it was not entirely clear which patterns are general and which are confined to some specific regional conditions. The fill this knowledge gap, I collected all studies on long-term trends in bird abundance in Europe and North America, which I was aware of, and made a meta-analysis of their results. Using linear mixed-effects models, I found a significant decrease in open-habitat species, probably as a result of agricultural intensification and abandonment of agricultural land. This pattern was consistent regardless of region or time period...
