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.

Narrative methods in literary reportages of Wojciech Tochman
Beshirová Idris, Esther ; Hájek, Roman (advisor) ; Čeňková, Jana (referee)
In this thesis I deal with three literary reportages from the collection Pánbůh zaplať by the Polish journalist and writer Wojciech Tochman who represents the Polish School of Reportage. These are the reportages Člověk, který vstal z kolejí, Vzteklý pes and Mojžíšův keř. I focus on what kind of narrative techniques Tochman uses in the process of writing reportages, what kind of function they have and if the usage of these narrative techniques influences the trustworthiness of a literary reportage. In the case studies I analyze every reportage with the help of a one chosen narrative technique. In the reportage Člověk, který vstal z kolejí I focus on the narrative gaps, in Vzteklý pes I deal with the usage of focalisation and in Mojžíšův keř is the main focus the storytelling through characters. Literary analyses show that the narrative techniques are used for better coherence and impresivness of Tochman's texts. These techniques help to express experiences of described characters and allow an independent interpretation to the reader. They are also used as references to important social phenomenona which enable to Tochman to bring universal testimony about the subjects of literary reportages. The thesis also deals with the problem of the trusthworthiness of literary reportages which leads to an...

Gottstein, Yuliya ; Reifová, Irena (advisor) ; Vochocová, Lenka (referee)
This master's thesis focuses on the credibility of social media as news sources in journalistic practices in the Czech Republic. The paper is based on the sociological conceptualization of trust put forward by Niklas Luhmann and Piotr Sztompka and its modern adaptation by media scholars, e.g. Thorsten Quandt. The aim of this work has been to find out through thirteen substantive, one- on-one interviews with readers of the print and online media editions of Krkonošský deník how the credibility of news stories depend on the information sources used. The thesis includes the theoretical part that is based on the theoretical conceptualization of trust: from the main concepts and conflict topics to the journalistic practices that should ensure trustworthiness and audiences' perceptions of trustworthiness. The Methodology section describes the area of qualitative research and related procedures, which include a detailed description of the data collection method, which is a semi-structured, in-depth interview, and the characteristics of the research sample. In findings the results of the research from the data obtained through interviews conducted with respondents are interpreted. The conclusion of the thesis is dedicated to summarizing the research results.

Monitoring the social impact as a tool to increase the credibility of non-profit organizations
Nejedlá, Barbora ; Vrzáček, Petr (advisor) ; Komberec Novosadova, Barbora (referee)
This diploma thesis combines the method of monitoring the social impact with the phenomenon of the credibility of non-profit organizations. According to the results of public opinion polls in the Czech Republic, confidence in non-profit organizations has been low for a long time. Lack of transparency and low awareness of the activities and principles of non- profit organizations can be reasons for distrust in non-profit organizations. This thesis aims to present a method of monitoring the impact of those who do not yet know it using a manual based on the results of action research and thus contribute to greater transparency and better presentation of results and later greater credibility of organizations. The theoretical part of the thesis deals with trust and credibility, the method of monitoring the impact and the introduction of the non-profit sector of the Czech Republic. Emphasis is placed on a multi-sided view, practical examples, and data support. The empirical part of this work uses action research and human-centerd design to connect trust and credibility with the method of monitoring the impact in the sphere of non-profit organizations. The result of action research is that the implementation of the impact monitoring method brings with it many changes, which can be distinguished into...
