Designing a good customer relationship is important for a company to function and trust plays a major role when building customer relationships. The importance of this becomes more highlighted in the context of non- testable, non-testable products online since the customer cannot evaluate anything physically beforehand. Here trust is the mediator for a successful customer relationship within online shopping. The purpose of this study was to explain the impact of Source of Information and Credibility of Information on online consumer trust in the setting of non-testable, non-returnable products online. With a deductive approach to this quantitative research, the methodology of operationalization was used to measure the theoretical framework and to derive two hypotheses to be rejected or accepted based on the results of an online self-completion questionnaire. The questionnaire got a total of 74 answers that were analyzed by running a multiple regression analysis. The result of this study is that one hypothesis is accepted, the Credibility of Information has a positive relation to Trust when shopping non-testable, non- returnable products online, based on the positive relationship found. By accepting only one hypothesis, this resulted in a modified research model visually presenting the outcome. Which can be concluded that Credibility of Information has a positive relationship with Trust in the context of non- testable, non-returnable products online. Which implies that companies within this area should increase credibility in order to increase customer online trust.

The main purpose of the present study was to explore the effects of characteristics of information given in a job advertisement (amount of information and the specificity of the information) on the potential applicants&rsquo / willingness to apply to the job opening with the mediating roles of credibility of and satisfaction from the information, and attraction to the organization. In addition to that, the factors affecting the decision of the applicants to apply for the job posted such as application modes (internet, by hand in the same city the applicant lives, by hand in a different city than the applicant lives), different selection methods (interview, personality test, knowledge test), and personality characteristics (goal orientation and self-efficacy) were investigated. The study was conducted in three phases. In the first phase, one hundred and seven Middle East Technical University (METU) students were used to decide between two alternatives of goal orientation and two self-efficacy scales, which were translated into Turkish and adapted for the current study, to be used in the main study by determining the validity and reliabilities of the scales. The second phase was the manipulation check, conducted to test the clarity and meaningfulness of the newly developed job advertisements and questions related to the research hypotheses. Thirty-two METU students were used for the second phase. The final phase was the main study. One hundred and fifty four METU students from Electrical and Electronics Department were used to examine the hypotheses of the study.The students were randomly assigned to the three different versions of job advertisement. Additionally, a questionnaire package was given to each participant. The results supported most of the main hypotheses and the proposed model except for the mediating effect of satisfaction. Advertisement type affected the willingness to apply to the job of potential applicant and this relation was mediated by credibility and credibility was mediated by attractiveness to the organization. A main effect of application mode was found for change in application decision, but no interaction was found between application mode and different attraction levels. Goal orientation found to be affecting applicants&rsquo / decision change for different selection methods. Self-efficacy failed to predict decision change for application for different selection methods. Results are discussed along with the strengths and limitations of the study and suggestions for future research.

This work describes the problem of information credibility in state institutions with the help of using various methods (deduction, induction and synthesis). Work describes mainly theory but also some existing approaches in real work of this institutions. The work describes the problem beginning from collecting information, verifying information and information sources, related credibility, concepts, typologies and so on. Then, it describes the phenomenon of misinformation (or disinformation) and clarifies if this phenomenon is a part of real daily work of certain state institutions. Then in work is described the Ministry of Foreign Affairs of the Czech Republic and their approach to information (typology of information, resources, verifying information, actors which collect information). In addition, work presents such institution as the Office for Foreign Relations and Information, which is also a state institution and is a leading supplier of information to the MFA. Understanding the issue of such a sensitive topic in such closed institutions is based on publicly published sources. In work are also described methodologies of verifying information and procedures of risk management used in the situation of obtaining false information. At the same time, work contains a few of author's solutions for some parts of the work.
