Schools and teachers have been subject to a number of debates and often face contradictory demands. In this study we analyse radio interviews with three Czech experts on education. Building on ethnomethodology, namely conversation analysis and membership categorisation analysis, the study was guided by two research questions: (1) What practices and membership categorisation devices do the experts employ when speaking of Czech education and schools? and (2) How do the experts relate to teacher professionalism when characterising Czech education? The analysis shows how the expert’s credibility is negotiated, how they problematise gaining fundamental knowledge and skills at schools and situate the learning of “important things” outside school, and how they claim that Czech teachers teach badly while downgrading positive results of Czech schooling. This way the experts cast doubt on basic characteristics of teacher professionalism and thus undermine trust in the professional project in teaching. Školy a učitelé jsou předmětem množství debat a často čelí rozporuplným požadavkům. V této studii analyzujeme rozhlasové rozhovory se třemi českými odborníky na vzdělávání. Za využití etnometodologie, zejména konverzační analýzy a členské kategorizační analýzy, studie odpovídá na dvě výzkumné otázky: (1) Jaké praktiky a inventáře sociálních kategorií používají odborníci, když mluví o českém vzdělávání a školách? (2) Jak se odborníci vztahují k profesionalismu učitelů, když charakterizují české vzdělávání? Analýza ukazuje, jak je důvěryhodnost odborníků v rozhovorech vyjednávána, jak experti problematizují získávání základních znalostí a dovedností ve škole a situují učení se "důležitých věcí" mimo školu a jak tvrdí, že čeští učitelé vyučují špatně, a současně bagatelizují pozitivní výsledky českého vzdělávání. Tímto způsobem odborníci zpochybňují základní charakteristiky profesionalismu učitelů, a tak podrývají důvěru v profesionální projekt v učitelství.

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.

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...

V oblasti automatického rozpoznávání obličejů (AFR) byla vyvinuta celá řada metod, které dosahují vynikající úspěšnosti v případě kontrolovaných podmínek. Pokud podmínky nejsou kontrolované nebo jsou kontrolované jen v omezené míře, je úspěšnost významně snížena. Poskytnutí informace indikující pravděpodobnost, jestli je výsledek rozpoznání správný, je tedy velmi žádoucí. Tato práce se zabývá použitím konformního prediktoru (CP), který umožní k výstupu AFR metod přidat dobře kalibrované míry důvěry. CP je kombinován s klasifikátory založenými na deskriptorech POEM a SIFT. Dále je použita vážená kombinace obou klasifikátorů. Porovnáváme úspěšnost pěti způsobů výpočtu míry nonkonformity. Many Automatic face recognition (AFR) methods achieve a high recognition accuracy when the environment is well-controlled. In the case of moderately controlled or fully uncontrolled environments however, the performance of most techniques is dramatically reduced. As a result, the provision of some kind of indication of the likelihood of a recognition being correct is a desirable property of AFR techniques. This work investigates the application of the conformal prediction (CP) framework for extending the output of AFR techniques with well-calibrated measures of confidence. In particular we combine CP with one classifier based on POEM descriptors, one classifier based on SIFT descriptors, and a weighted combination of the similarities computed by the two. We examine and compare the performance of five nonconformity measures.

This work studies factors of e-shops credibility on the field B2C. The aim of the work was to work out a summary of recommendations for businessmen, who deal with or consider internet marketing, and to introduce particular suggestions for a specific e-shop.

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...

The credibility of a grey literature digital repository can be supported by a specialized audit. An audit of credibility declares that the digital repository is not only a safe place for storage, providing access and migrating to new versions of document formats, it also asserts the care components required of a digital repository environment, including the mandate, typology, policy, team, etc. This audit is very important in showcasing to participants and users the quality and safety of the data process. This paper will present DRAMBORA (Digital Repository Audit Method Based on Risk Assessment), a methodology and tool for auditing a trustworthy digital repository of grey literature. DRAMBORA is an online instrument which helps organizations develop documentation and identify the risks of a digital repository. DRAMBORA is accessible from http://www.repositoryaudit.eu. The paper will also summarize prevailing advantages and disadvantages of DRAMBORA. The second part of this paper will describe the audit of the National Repository of Grey Literature (NRGL) as a trustworthy digital repository using DRAMBORA as part of creating a digital repository of grey literature in the National Technical Library (NTK). The most important outcome of the audit was represented by the identified risks connected to the repository and potentially endangering its operation, quality, image, and other features. The main principle of the DRAMBORA audit and, at the same time, its main contribution, is its iteration (i.e. its repetition after a certain time period in new conditions when the original risks are reassessed; the measurements adopted for solution are assessed and new risks are identified).
