Bagging is a procedure averaging estimators trained on bootstrap samples. Numerous experiments have shown that bagged estimates often yield better results than the original predictor, and several explanations have been given to account for this gain. However, six years from its introduction, bagging is still not fully understood. Most explanations given until now are based on global properties ...

Digital inequality, or the unequal access and use of information communication technologies, inhibits under-privileged people from opportunities in the digital world. Although government and private organizations have devoted considerable resources to address this inequality, issues remain unsolved. A theory-based investigation of the phenomenon is essential for effective policy-making and inte...

This article describes the process by which one study utilized qualitative methods to create items for a multi dimensional scale to measure twelve step program affiliation. The process included interviewing fourteen addicted persons while in twelve step focused treatment about specific “pros” (things they like or would miss out on by not being involved in twelve-step programs) and “cons” (thing...

Foresight is currently perceived as a critical activity in the development of innovation policies and corporate strategies. While there are many descriptions of the benefits of foresight, there is little research into how these benefits are created. In addition, although the view of innovations has shifted towards a systems understanding, the same has not happened with foresight, which is large...

In this paper we propose a method to robustly estimate linear regression quantiles with censored data. We adjust the estimator recently developed by Portnoy by replacing the Koenker-Bassett regression quantiles with the regression depth quantiles. The resulting optimization problem is solved iteratively over a set of grid points. We show on some examples that, contrary to the Koenker-Bassett ap...

Protein phosphorylation plays a fundamental role in the biology and invasion strategies of apicomplexan parasites. Many apicomplexan protein kinases are substantially different from their mammalian orthologues, and thus constitute a landscape of potential drug targets. Here, we integrate genomic, biochemical, genetic and evolutionary information to provide an integrated and up-to-date analysis ...

The present study investigates fundamental frequency as a potential basis for segmentation in models of infant speech segmentation. Pairs of segments that were similar either in terms of fundamental frequency envelop or in terms of transcribed content were found in three different speech styles: speech directed to three-month-olds, speech directed to twelve-montholds and speech directed to adul...

We present a zero dimensional matrix model based on U Sp(2k) with supermultiplets in symmetric, antisymmetric and fundamental representations. The four dimensional compactification of this model naturally captures the exact results of Sen [1] in F theory. Naive counting tells that the model describes twelve spacetime dimensions. Eight dynamical and eight kinematical supercharges are found, whic...

On 21 June 2011, the DSM Science & Technology Awards recognized and rewarded outstanding innovative young scientists active in fundamental and applied research. As in previous years, an international judging committee honored creative and groundbreaking PhD research. Twelve finalists, the top candidates from Switzerland, Austria, France and southern Germany, were invited for the final competiti...

Twelve years ago I introduced a B course at Ensimag, a wellknown french Mathematics and Computer Science engineer school. In this paper I describe this experiment and the evolution of the contents of this course. In particular I present a set of fundamental concepts that can be easily illustrated with the help of the B framework. I also present some unpublished examples and theoretical results.
