Abstract: Extracting trading information from the stock market to construct accurate forecasting models that filter signals and noise is a challenge. This research employs big data analytics to construct a computation platform for stock selection and trading strategies. It adopts elite particle swarm optimization (EPSO) to elucidate optimal trading opportunities and combines growing hierarchical self-organizing map (GHSOM) and EPSO in its stock selection strategy. EPSO–GHSOM distinguishes companies’ operating profitability, identifies price signals, and sets decision rules for buying and selling.

Abstract: The goal of this research was to examine information needs of students in democratic society with the emphasis on their perception and use of the public library in satisfying democratic and civil rights. In the research were used quantitative methodology (printed questionnaires) and participants were students of information sciences in Osijek (Croatia). Although research results showed that students mostly never (41%) or rarely (40%) searched for the information regarding their civil and democratic rights, they found that these rights were mostly important to them (mean 3.28). Less than a half of the respondents had information needs for democratic and civil rights in the area of education (42%). As expected more than a half of the respondents informed themselves about civil and democratic rights over the Internet (57%), while only 6% of them looked for that information in public libraries. Students mainly agreed that public libraries should provide access to the civil and democratic rights information (mean 4.13) by preparing public lectures, discussions, workshops or appropriate materials such as brochures (63%). Research data can be useful for public libraries in organizing collections and services for the support of democracy and civil rights.
