The main aim of this paper is to forecast gold and silver daily returns with advanced regression analysis using various linear and non-linear models. ARMA models are used as a linear benchmark for comparison purposes with established non-linear models such as Nearest Neighbours and MultiLayer Perceptron (MLP), and Higher Order Neural Networks (HONN) whose application to financial markets is quite new. All models are assessed using statistical criteria such as correct directional change as well as financial criteria such as risk adjusted return. The main aim is to find which of these models generate the best returns and if nonlinear models can be used for generating excess returns in the precious metals market. This is achieved by implementing a trading simulation where the forecast is t...

A central argument of new institutionalism is that organizational success depends not only on efficient coordination and control of productive activities, but on conforming to institutionalized expectations. There is a dearth of empirical studies which analyze the effects of the adoption of institutionalized elements. In our study, we examine the effect of ISO 9000 certification on resource inflow of German mechanical engineering firms. Our findings suggest that organizations are actually rewarded for complying with institutionalized expectations and implementing ISO 9000 standards. Our findings also show that the readiness to comply with institutionalized norms led to different economic consequences in East and West Germany.

This paper describes an implementation of the Kurtosis and InfoMax algorithms for an independent components analysis in mixed-signal CMOS. Our design uses on-chip calibration techniques and local adaptation to compensate for the effect of device mismatch in arithmetic blocks and analog memory cells. We use our design to perform two-input blind source-separation on mixtures of audio signals and mixtures of EEG signals. Our experiments show that the hardware implementation of InfoMax consistently separates the signals within a normalized reconstruction error of less than 10%, while the reconstruction error of Kurtosis varies between 25% and 60%, due to its higher sensitivity to device mismatch and input statistics. Each circuit has a settling time of 8 µs, occupies a die area of 0.016-0.0...
