This paper presents some forecasting techniques for energy demand and price prediction, one day ahead. These techniques combine wavelet transform (WT) with fixed and adaptive machine learning/time series models (multi-layer perceptron (MLP), radial basis functions, linear regression, or GARCH)....

This article presents a framework for thinking about the fundamental activities of inference--data analysis and interpretation--by researchers using qualitative data. I contrast these two activities. For analysis I describe seven operations: categorization, abstraction, comparison,...

We report results from an Ultimatum Game experiment with and without pre-play communication, conducted both in a real-world experimental laboratory and in the virtual world Second Life. In the laboratory, we replicate previous results that communication increases offers and agreement rates...
