This master’s thesis studies stock returns forecasting power of microeconomic and macroeconomic variables for European listed companies. Listed companies are divided into six industries and we conduct an in-sample estimation with the Lasso and Elastic Net regression for α=0.5 and α=0.25 in order to compare the selection and the in-sample performance for the models built with the two regularization techniques. In a second step, we study the out-of-sample accuracy of the created models with several statistical tools with two time periods: one including the Covid-19 pandemic period and the other one without this time period. The results showed an insignificant relationship between stock returns and the predictive variables for both the training and testing data. Two possible explanations are either there a linear regression cannot forecast stock return as it is too volatile, or it is due to the huge number of outliers in our dataset. In conclusion, the return on equity, return on assets, net profit margin, debt-equity, earnings per share, price-to-earnings, earnings yield, dividend yield, dividend payout, book-to-market, inventory turnover, quick ratio, current ratio, inflation, long term yield and the GDP growth rate do not have prediction power on stock returns for European listed companies in the last decade.

This reprint is dedicated to the study of brain activity related to emotional and attentional involvement as measured by Brain–computer interface (BCI) systems designed for different purposes. A BCI system can translate brain signals (e.g., electric or hemodynamic brain activity indicators) into a command to execute an action in the BCI application (e.g., a wheelchair, the cursor on the screen, a spelling device or a game). These tools have the advantage of having real-time access to the ongoing brain activity of the individual, which can provide insight into the user’s emotional and attentional states by training a classification algorithm to recognize mental states. The success of BCI systems in contemporary neuroscientific research relies on the fact that they allow one to “think outside the lab”. The integration of technological solutions, artificial intelligence and cognitive science allowed and will allow researchers to envision more and more applications for the future. The clinical and everyday uses are described with the aim to invite readers to open their minds to imagine potential further developments.

Effective environmental decision-making is often challenging and complex, where final solutions frequently possess inherently subjective political and socio-economic components. Consequently, complex sustainability applications in the “real world” frequently employ computational decision-making approaches to construct solutions to problems containing numerous quantitative dimensions and considerable sources of uncertainty. This volume includes a number of such applied computational analytics papers that either create new decision-making methods or provide innovative implementations of existing methods for addressing a wide spectrum of sustainability applications, broadly defined. The disparate contributions all emphasize novel approaches of computational analytics as applied to environmental decision-making and sustainability analysis – be this on the side of optimization, simulation, modelling, computational solution procedures, visual analytics, and/or information technologies.
