The focus of the paper is to present an evaluation of a proposed decision-making model concept. The concept takes into account the quality of a currently used information system’s subsystem (the Business Intelligence subsystem in our case), as it is perceived by its current users. The Analytic Hierarchy Process (AHP) multi-criteria decision making method is used to support the concept with a hierarchical decision criteria structuring framework. A selected part of the DeLone and McLean’s (D&M) information system success assessment model is used for the determination of appropriate criteria (success factors). The D&M model is composed of information system quality assessment dimensions. These dimensions represent a solid base for surveying information system’s users according to their perception of key information system performance aspects. The presented model helps to combine opinions of the management and users successfully when carrying out important information system related decision. The results also illustrate the possibility of using the D&M model in a novel application together with the AHP method.

Psychology of Colors and its application in software is a part of a wider research related to Software Ergonomics. Nowadays, software tends to be faster, clever and even more complex. On the other side, the amount of applications, which people has to manage increases. However, user interface and all the communication between a man and a machine needs simplifying. One way how to do that is to dig into the knowledge and conventions, which users already have. Software needs to be brought near to the users maybe using the associations of the particular use-cases in the application with colors, which users already know and which are common to them. The research tries to find these associations, describe them and define the steps for the future research.

The aim of this paper is to introduce a summary and current state of the issue of predatory open access publishers and to critically discuss general predatory behaviour and related topics in the Czech and international context. The article summarizes outputs of the first foreign studies dealing with predatory publishers and journals. We find that although in the past three years, the issue of predation is actively addressed in foreign countries, the Czech higher education institutions are not prepared for this new phenomenon as well as most of academics and researchers do not know about it at all. The text highlights the threats with which the scientific community (science and education in general) is confronted and proposes countermeasures from the view of an individual and higher education institutions. At the end of the article, there are mentioned trends in the behaviour of predatory publishers and dilemmas which non-predatory journal publishers and international indexing databases are faced with.
