This article questions the preconceived notions that participants in virtual worlds are essentially consumers. Building on the existing scholarship around virtual worlds and notwithstanding the current character of virtual worlds, this paper explores aspects of End User Licence Agreements and notes the unfairness of their provisions, particularly the imbalance between user and developer interests governed by such contracts. It argues that the contracts cannot be regulated with consumer protection legislation, as interests such as property or intellectual property are beyond the scope of consumer protection regimes. Finally, recognising the phenomenon of constitutionalisation of virtual worlds, the article argues for stronger regulatory solutions in this domain, in order to strike a more appropriate balance between competing interests in virtual worlds.

It is well known that the process of tuning a fuzzy logic controller is almost always a very complex task, which is time consuming, very laborious and often requires expert knowledge of the controlled system. Mapping of fuzzy logic controller's parameters (rule base and membership functions of input(s) and output(s)) into a performance measure in a closed analytical form is near impossible to get, and thus the use of any classical optimization method is automatically ruled out. Knowing this, genetic algorithms with a fitness function in a form of cumulative response error represent a good choice of the optimization method. This approach enables the use of offline optimization of membership functions' parameters (which are being coded into chromosomes). Sugeno-Takagi fuzzy logic controllers with a proportional and a derivative component, and also with a fixed rule base are used in this approach. Experimental results of both simulations and validations on real systems are given in this paper and they show the good performance of this approach.

The main purpose of this paper is to present the finding of a research into modern management tools usage in companies in Bosnia and Herzegovina, in the climate of economic downturn. In trying to reduce uncertainty of business conditions in recession, and to create a sustainable competitive advantage, the necessity of an adequate response to changes and challenges for companies through the usage of management tools is gaining momentum. In this paper, we have presented research results of modern management tools usage and the level of satisfaction for companies that are operating in Bosnia and Herzegovina, in the context of financial crisis and economic downturn, and against the backdrop of the set targets of these companies. Results stem from a survey conducted among 46 executives in companies of all sizes, sectors, forms of organization and ownership. Regarding practical implications, the paper points to the usage of modern management tools in companies, following the global trends of tried-and-true management tools, positively correlated with the satisfaction coming from their implementation. We must emphasize that companies in Bosnia and Herzegovina are focusing more on usage of management tools that are promoting improved customer relationship management and customer segmentation, in the climate of persistent economic downturn. We believe that building stronger management capacities is under way for companies doing business in Bosnia and Herzegovina, as well as the implementation of some new data management tools. In this process of implementing new tools, additional managerial training of the staff is needed, which is supported by our survey findings.
