The credibility of news in the world of data journalism
Pilná, Barbora ; Jirák, Jan (advisor) ; Jirků, Jan (referee)
The term crisis of journalism is widely discussed nowadays. This paper examines whether journalism is in crisis, or whether it is a development caused by changes in the digital world. It also examines possible causes of this crisis and transformation in the digital world. One of the main causes of this is a perceived loss of credibility of the information given to the public. Therefore, there is a deeper interpretation of what trust and trustworthiness is and what can dis/trust cause in the society. In the context of the changes which journalism faces today, it describes the transformation of the role of the audience to active self-editor and outlines how the audience must orientate in the news itself. Otherwise, the media focused on earnings will continue to thrive on sensationalism and moral panics that will negatively effect social reality. In the empirical part this paper deals with the case of Břeclav in 2012, which is an exemplary example of moral panic with consequences.

Comprehensive Web Audit Methodology
Sekulová, Kateřina ; Vlasák, Rudolf (advisor) ; Očko, Petr (referee)
A web site is often the first point of contact between the user and another person or company or organization, so that in the electronic world, a web site is like a calling card. Ideally therefore, a web site should load relatively quickly to prevent the user from looking elsewhere even before the web site has opened. Also, the web site should have a pleasant design to make it user-friendly, it should display helpful content, be widely accessible and, last but not least, fulfil the aims for which it was created. It is the responsibility of web site designers, programmers and creators to ensure that web sites fulfil their function. A web site audit - either during or after its construction - is the best way of checking that all factors relating to access, use, technical processes and other criteria function correctly. There are many audit companies on the market today, each of them offering the customer its own particular perspective, evaluation according to different criteria and audit conducted using various methods. Therefore, the first part of this work contains an overview of different perspectives used to assess the quality of web sites, as well as designers and the specific methodology they apply during web site audits. The theoretical part of this methodology ends with a way how the success and...

Disruption of movement or cohesion of groups through individuals
Vejmola, Jiří ; Neruda, Roman (advisor) ; Děchtěrenko, Filip (referee)
Title: Disruption of movement or cohesion of groups through individuals Author: Jiří Vejmola Department: Department of Theoretical Computer Science and Mathematical Logic Supervisor of the master thesis: Mgr. Roman Neruda, CSc., Institute of Computer Science of the ASCR, v. v. i. Abstract: Just a few of informed and like-minded individuals, guides, are needed to lead otherwise naive group. We look at some of the possible changes that can be caused by the presence of another informed individual with different intentions, an intruder. It is implied that he cannot cause anything significant under normal circumstances. To counter that and to increase his chances of success we intruduce a new parameter - credibility. We explore how it changes the overall behaviour. We show that by applying it to the intruder his influence over others increases. This in turn makes naive individuals more willing to follow him. We show that if the right conditions are met he can eventually become the one who leads the group. Keywords: multi-agent system, swarm intelligence, emergence, credibility

The Change of the Image of Photojournalism in Digital Era
Novák, Vojtěch ; Kera, Denisa (advisor) ; Vilgus, Petr (referee)
We will discuss here the issue of manipulation in the digital era of photojournalism. At first we will describe the relation between photography and its referent inculding its ability to represent the reality. Depicting the contrast between analogue and digital photography we will point out the independent position of digital photography from its referent, which is creating better possibilities for manipulation and decreasing the credibility of photography. Then we will analyze the text The Dusk of Photojournalism? that is reflecting these perspective and offering the solution increasing the position of the relation between photography and its referent. By contrast we will analyze the text called Photojournalism is dead, long live photojournalism. Why digitization can increase the credibility of journalistic photography? which considers this perspective as obsolete and offers us the new perspective of the relation between photography and its viewers, that could increase the credibility of photography in photojournalism. According to these two major perspectives we will point out whether it is possible to consider this option of photography - viewers relation as a relevant alternative. Based on these conclusions we will point out the major point of credibility of journalistic photography and imply...

Assessed psychological characteristics of human face in depedence on socio-economical status
Linke, Lenka ; Kleisner, Karel (advisor) ; Pivoňková, Věra (referee)
Human face is a complex semantic organ, which among others reflects also human individuality due to the high variance of facial morphologies. This study examines the relationship between psychological characteristics and social status. Moreover, we have analyzed variability in facial form and its relation to a particular social rank. The study was performed on a set of photographs containing 55 pictures of men in a management position. These photographs were evaluated by 47 male (average age - 22 years) and 77 female (average age 21,6 years) respondents. The data were analyzed by means of classical methods of statistical testing as well as geometric morphometrics methods. This study tests whether there is a relation between three psychological characteristics - dominance, attractiveness, trustworthiness - and social status. The effect of perceived dominance and attractiveness on social status were not significant. Nevertheless, we found statistically significant relationship between perceived trustworthiness and social rank. We were not able to detect morphological facial structures, which would distinguish the heads of department from the chief executive directors. However the parametric tests discovered statistically significant differences between the facial morphology of a trustworthy and...

Differences in perception of the human face is caused by variability in facial features, which stands in the face properties, such as attractiveness, dominance and trustworthiness. This literature review focuses on the perception of trustworthiness and its impact to social interactions. The attention is also paid to possible evolutionary mechanisms such as sexual selection. Moreover, this work deals with the neurohormonal causes in the perception of trustworthiness, wherein the subcortical brain region called the amygdala plays the main role.

Analysis of the relationship between media popularit y and perceiving their credibility
Mičánek, Pavel ; Jirák, Jan (advisor) ; Wolák, Radim (referee)
The goal of our thesis was to study the relation between trust and media. Therefore, we have introduced some selected theoretical approaches of trust in relation to society and we have also formulated our own theoretical implications on the basis of this review which we have later used in our research of trust in media. In the theoretical part we have defined the concept of trust in terms of two key principals of trust based on the rational and intuitive understanding of trust. We have described hierarchical levels of trust in society and then we have focused on interpersonal and system level. We have reviewed selected theoretical approaches to trust and we have outlined the development of trust within sociology. We have explained the function of media in society and pointed out the reasons of the interest in studying trust in media together with the review of the concepts of media effects. Then we have briefly summarized the empirical research and mentioned the situation in the Czech Republic. Finally we have suggested some phenomenons that may cause the decrease in trust are named. In the research part we have concerned with the analysis between media source popularity operetionalised as a frequency of using of the media source and its credibility perceived by recipients. Another research goal...
