On the forecast accuracy and consistency of exchange rate expectations: The Spanish PwC Survey.

We examine the predictive ability and consistency properties of exchange rate expectations for the dollar/euro using a survey conducted in Spain by PwC among a panel of experts and entrepreneurs. Our results suggest that the PwC panel have some forecasting ability for time horizons from 3 to 9 months, although only for the 3-month ahead expectations we obtain marginal evidence of unbiasedness and efficiency in the forecasts. As for the consistency properties of the exchange rate expectations formation process, we find that survey participants form stabilising expectations in the short-run and destabilising expectations in the long- run and that the expectation formation process is closer to fundamentalists than chartists.

Private (Brown) Eyes: Ethnicity, Genre and Gender in Crime Fiction in the Gloria Damasco novels and the Chicanos Comic Series

The representation of women in crime fiction has traditionally been a complicated one. Consistently forced into secondary characters (assistants, girlfriends, or damsels in distress) the most active role a female character could aspire to was that of the femme fatale, a pit of perdition, an unwelcome distraction for a man looking for truth and justice. This traditional approach to the genre has been challenged in the last decades by women acting as detectives, trusted with solving their cases in a hostile male world. Similarly, the traditional white male protagonist has been contested by fictions where ethnic minorities are not just consigned to the criminal world, but where detectives are members of ethnic groups, and can use their knowledge of the community to solve the case. This essay focuses on the crossroads of ethnic and women’s detective fiction, specifically the Gloria Damasco series by Chicana writer Lucha Corpi and the graphic novel Chicanos (Trillo and Risso, 1996). Both protagonists (Gloria Damasco, a Chicana clairvoyant detective, and “poor, ugly, and a detective” Alejandrina Yolanda Jalisco) must face both the dangers of investigating criminal cases and discrimination in their professional surroundings due to their gender and ethnicity. By contrasting these texts, the essay elucidates the importance of specific cultural products, their connection to (and defiance of) canonical forms of the genre, and their rejection of generic and gender expectations.

Search for first harmonic modulation in the right ascension distribution of cosmic rays detected at the Pierre Auger Observatory

We present the results of searches for dipolar-type anisotropies in different energy ranges above 2.5 x 10(17) eV with the surface detector array of the Pierre Auger Observatory, reporting on both the phase and the amplitude measurements of the first harmonic modulation in the right-ascension distribution. Upper limits on the amplitudes are obtained, which provide the most stringent bounds at present, being below 2% at 99% C.L. for EeV energies. We also compare our results to those of previous experiments as well as with some theoretical expectations. (C) 2011 Elsevier B.V. All rights reserved.

Dynamical generation of a gauge symmetry in the double-exchange model

It is shown that a bosonic formulation of the double-exchange model, one of the classical models for magnetism, generates dynamically a gauge-invariant phase in a finite region of the phase diagram. We use analytical methods, Monte Carlo simulations and finite-size scaling analysis. We study the transition line between that region and the paramagnetic phase. The numerical results show that this transition line belongs to the universality class of the antiferromagnetic RP^(2) model. The fact that one can define a universality class for the antiferromagnetic RP^(2) model, different from the one of the O(N) models, is puzzling and somehow contradicts naive expectations about universality.
