Defensive drive
Zapletalová, Kateřina ; Tylšar, Vladimír (referee) ; Semela, Marek (advisor)
The diploma thesis deals with the issue of driver education and practice safe, dangerous and aggressive driving. The aim is to map the issue of safe and defensive driving and define the principles of defensive driving. The first part deals with the theory of defensive driving, which analyzes psychologically and legally sides of that problem. Another part deals with road safety, which is described in the context of direct and indirect indicators of road safety. The research then analyzes in detail the specific situation on the road that leads to accidents. This analysis is performed on based data of real accidents. Of particular situations accidents are then defined the principles of defensive driving.

Verbal aggressiveness in discussion on the webside iDNES.cz
WAGNEROVÁ, Hana
This thesis deals with verbal aggressiveness in internet discussions on the website iDNES.cz. It researches the course of communication between the participants of the discussions and it analyses their contribution from the stylistic and lexical point of view. The aim of this thesis is to find out in what manner the aggressiveness is expressed, what language devices the speakers use and where the aggressive behaviour and expressions occur most often. The study attempts to determine the reasons for this demeanour and whether it could be prevented. In its first part, the paper analyses internet discussions as a type of a communication process, studies its character and its relation to other kinds of communication. In its second part, it explores specific language devices that can be found in the discussions. The material used for the analysis is derived from the reporting section on the website iDNES.cz.

Diversity of Neofabraea species causing bull's eye rot in the Czech Republic
Pešicová, Kamila ; Novotný, David (advisor) ; Mazáková, Jana (referee)
Neofabraea is a genus of an important plant pathogenic fungi having worldwide appearance. Four Neofabraea species are responsible for bull's eye rot of pome fruits. The aim of this thesis was to investigate which of these species occur in the Czech Republic. 81 isolates were collected during a two- year period and they were identified using PCR fingerprinting (primers ERIC 1R and M13-core) and DNA sequencing (ITS, mtSSU and tub2). The results showed that species N. alba, N. perennans and Cryptosporiopsis kienholzii occur in the Czech Republic. According to available information, this is the second record of C. kienholzii in Europe. One isolate (KP4) failed to be identified as any of the species. KP4 is very close to C. kienholzii, but it can be distinguished both biologically and genetically. Furthermore, the aggressiveness of individual species was compared.N. perennans and strain KP4 proved to be most aggressive, the least aggressive is C. kienholzii. Two N. alba strains (KP36 and KP37) isolated from healthy apple fruit and leaf are pathogenic for apple fruits. Keywords: aggressiveness, Cryptosporiopsis kienholzii, Dermateaceae, Helotiales, apple tree, Malus, PCR fingerprinting, postharvest diseases Powered by TCPDF (www.tcpdf.org)

A traffic flow with a bottelneck
Kovařík, Adam ; Janovský, Vladimír (advisor) ; Vejchodský, Tomáš (referee)
Title: A traffic flow with a bottelneck Author: Adam Kovařík Department: Department of Numerical Mathematics Supervisor: prof. RNDr. Vladimír Janovský, DrSc. Supervisor's e-mail address: janovsky@karlin.mff.cuni.cz Abstract: In this paper we study a microscopic follow-the-leader traffic model on a circu- lar road with a bottleneck. We assume that all drivers are identical and overtaking is not permitted. We sketch a small part of the rich dynamics of the model including Hopf and Neimark-Sacker bifurcations. We introduce so called POM and quasi-POM solutions and an algorithm how to search them. The main goal of this work is to investigate how the optimal velocity model with a bottleneck deals with so called aggressive behavior of dri- vers. The effect of variable reaction time and a combination of both named factors is also tested. Using numerical simulations we'll find out that aggressiveness and faster reactions have positive effect on traffic flow. In the end we discuss models with two bottlenecks and with one extraordinary driver. Keywords: dynamical systems, ODEs, traffic flow, bottleneck, aggressiveness. 1

Influence of Computer Games on Aggressive Behaviour of the Pupils of the Older School Age
Zavadilová, Petra ; Kučírek, Jiří (advisor) ; Hanušová, Jaroslava (referee)
The diploma work focuses on a topic which is often discussed in the Czech Republic as well as worldwide. The topic in question is the influence of computer games with elements of aggression and violence on aggressive behaviour of teenagers. The work consists of two parts - a theoretical and an empirical one. The theoretical part has four chapters dealing with theoretical knowledge on the subject. In the empirical part the qualitative research strategy was used - questionnaire method and semi structured interview. The research sample consisted of five pupils from the 9th grade of an elementary school. The main aim of the diploma work will be to establish the subjective perception of the influence of computer games with elements of aggression and violence on aggressive behaviour of pupils of older school age. The secondary aim will be establishing the attitudes of the pupils of older school age to violent and aggressive scenes in computer games and mapping the intrusion of computer games into everyday life of pupils from the point of view of computer games preferences and the time they spend playing computer games during the day. Qualitative research showed that four out of five respondents really subjectively feel that computer games with elements of violence and aggression strengthen their...

Bullying in the Intensive Care Units
Samcová, Olga ; Mellanová, Alena (advisor) ; Hladíková, Lenka (referee)
Bullying in the intensive care units. The main mission of this thesis is to describe an issue called mobbing. The primary target is to get information about rate of bullying in the intensive care units in south Bohemia, especially in Prachatice and Strakonice city and to know how many percent of employees / paramedics of the intensive care units were already touched by bullying. This kind of information we got by anonymous questionnaires, set up from 23 questions with open and closed form. In theoretical part I deal with actual status, explaining term of mobbing, bossing, causes of bullying, characteristic of the participants, bullying in the health service in the Czech republic. In the conclusion I show prevention and tolerance of mobbing and bossing. In practical part I point on assesment of hypothesis and evaluation of the target of my thesis. I suppose that the chicane show up in small measure on the workplace of the intensive care units. From my point of view I think that women working in the intensive care units are getting in a touch of bullying much more than men. In this part I want to show a methodology of research, parameter of complex and evaluation of research. In conclusion I get back to evaluation of research and starting a discussion. Key words: mobbing, bullying, bossing, conflict,...
