I present a model that can transform discounts on closed-end mutual funds into a measure of investor sentiment about the ability of fund managers to beat the market. It is demonstrated that this measure of sentiment varies positively with capital flows into open-end mutual funds, which are actively managed, and negatively with capital flows into index funds, which are passively managed. This is...

Abstr act This paper reports the participation of the Spanish Distance Learning University (UNED) in the First Answer Validation Exercise (AVE) celebrated within the Cross Language Evaluation Forum (CLEF) 2006 edition. The system works for the Spanish language. It is based on a Support Vector Machine (SVM) classification of the pairs given by the organization. This classifica...

The usual supermembrane solution ofD = 11 supergravity interpolates between R11 and AdS4× round S7, has symmetry P3×SO(8) and preserves 1/2 of the spacetime supersymmetries for either orientation of the round S7. Here we show that more general supermembrane solutions may be obtained by replacing the round S7 by any seven-dimensional Einstein space M7. These have symmetry P3 × G, where G is the ...

Textual Entailment Recognition (RTE) is a recently proposed task, aiming at capturing the means through which textual inferences can be made. Moreover, using such a module is meant to contribute to the increase in performance of many NLP applications, such as Summarization, Information Retrieval or Question Answering, both for answer ranking as well as for answer validation. This article presen...

Organohalide respiration is an anaerobic bacterial respiratory process that uses halogenated hydrocarbons as terminal electron acceptors during electron transport-based energy conservation. This dechlorination process has triggered considerable interest for detoxification of anthropogenic groundwater contaminants. Organohalide-respiring bacteria have been identified from multiple bacterial phyl...

Beam-driven plasma wakefield acceleration using low-ionization-threshold gas such as Li is combined with laser-controlled electron injection via ionization of high-ionization-threshold gas such as He. The He electrons are released with low transverse momentum in the focus of the copropagating, nonrelativistic-intensity laser pulse directly inside the accelerating or focusing phase of the Li blo...
