First impressions matter: Signalling as a source of policy dynamics

We first establish that policymakers on the Bank of England's Monetary PolicyCommittee choose lower interest rates with experience. We then reject increasingconfidence in private information or learning about the structure of the macroeconomy as explanations for this shift. Instead, a model in which voters signal theirhawkishness to observers better fits the data. The motivation for signalling is consistent with wanting to control inflation expectations, but not career concerns orpleasing colleagues. There is also no evidence of capture by industry. The papersuggests that policy-motivated reputation building may be important for explainingdynamics in experts' policy choices.

Descrição da larva de Popanomyia femoralis Kertész, 1909 e do pupário de Engicerus major Lindner, 1964 (Diptera, Stratiomyidae)

The larva of Popanomyia femoralis and puparium of Engicerus major are described. The larvae were collected under the bark of fallen trees in an area near the tropical rain forest at Ilha da Marambaia (23º 04'15''S-43º53'59''W-sea level) and Cabo Frio (22º52'46''S-42º01'07''W-4 m), State of Rio de Janeiro, Brazil. Biological notes are presented. The larva of Popanomyia femoralis and puparium of Engicerus major are compared with those of Chalcidomorphina aurata Enderlein, Cosmariomyia argyrosticta Kertész, Dactylodeictes lopesi Lindner and Vittiger schnusei Kertész, other species of the same subfamily.

Discrete devaluations and multiple equilibria in a first generation model of currency crises

The first generation models of currency crises have often been criticized because they predict that, in the absence of very large triggering shocks, currency attacks should be predictable and lead to small devaluations. This paper shows that these features of first generation models are not robust to the inclusion of private information. In particular, this paper analyzes a generalization of the Krugman-Flood-Garber (KFG) model, which relaxes the assumption that all consumers are perfectly informed about the level of fundamentals. In this environment, the KFG equilibrium of zero devaluation is only one of many possible equilibria. In all the other equilibria, the lack of perfect information delays the attack on the currency past the point at which the shadow exchange rate equals the peg, giving rise to unpredictable and discrete devaluations.

Abcès du sein: privilégier la ponction-aspiration échoguidée [Ultrasonography-guided drainage should be considered as the first-line approach for breast abscesses treatment].

The abscesses of the breast are puerperal or non puerperal. The Staphylococcus aureus is the most common germ. The diagnosis is based on clinical criterias and confirmed by the ultrasonography. The percutaneous ultrasonography-guided drainage must be proposed in first intent to treat. Surgical treatment is still valid with a relapsing or chronic abscess, or after the non operative processes have failed.

Description of the larva and pupa of the papaw borer weevil Pseudopiazurus papayanus (Marshall) (Coleoptera, Curculionidae, Piazurini)

Larvae, pupae and adults of the piazurine weevil Pseudopiazurus papayanus (Marshall, 1922) are associated with Carica papaya Linnaeus,1753 (Caricaceae). The larval and pupal stages are described and illustrated. The sexual differences in the last abdominal segments of the pupae are also illustrated.

Immatures of Heterispa vinula (Erichson) and Physocoryna scabra Guérin-Méneville (Coleoptera, Chrysomelidae, Cassidinae, Chalepini)

Larva and pupa of Heterispa vinula (Erichson, 1847) and larva of Physocorina scabra Guérin-Méneville, 1844 are described and illustrated. The material of H. vinula was collected feeding on Sida carpinifolia (L.f.) K. Schum (Malvaceae) in the city of São Paulo (Ipiranga and Mooca districts), and of P. scabra on acerola (Malpighia glabra L.) (Malpighiacea) in Cruz das Almas, Bahia. Larvae of genus Physocorina are described for the first time.

First records of Collembola (Ellipura) from the State of Paraíba, Northeastern Brazil

This paper presents the first records of the Collembola fauna in four localities of State of Paraíba, Northeastern Brazil. These records represent the first list of species of Collembola for the State of Paraíba. The research adds new records for Brazil of six genera and one species. Furthermore, thirteen undescribed species are presented.

A new spermophagous species of Heilipus Germar from the Amazonian Region (Coleoptera, Curculionidae, Molytinae)

Heilipus odoratus sp. nov. (type locality: Brazil, Amazonas, Manaus) is described based on adults reared from seeds of Aniba rosaeodora Ducke (Lauraceae), popularly called "pau-rosa". The species is spermophagous and develops from egg to adult inside the seeds. The new taxon is compared with the similar Heilipus draco (Fabricius, 1801). Illustrations of larva, pupa, adult and of important structures for species identification are given, including the male and female genitalia, figured for the first time for a species of Heilipus.

Sclérose en plaques: au-delà des traitements de première ligne [Multiple sclerosis: beyong first line therapies].

We are currently experiencing a key period in the management of patients with relapsing remitting multiple sclerosis. The application of new criteria allows early diagnosis, thus at a stage when the available immune treatments are the most likely to show a good efficacy. The therapeutic offer is expanding but its complexity too. It is thus important, for a given patient, to assess as precisely as possible the degree of severity of his/her disease, in order to give the drug with the optimal risk/benefit ratio.

High prevalence of major cardiovascular risk factors in first-degree relatives of individuals with familial premature coronary artery disease--the GENECARD project.

BACKGROUND: Hypertension, hypercholesterolemia, obesity and smoking are highly prevalent among patients with familial premature coronary artery disease (FP-CAD). Whether these risk factors equally affect other family members remains unknown. METHODS: We examined 222 FP-CAD patients, 158 unaffected sibs, 197 offspring and 94 spouses in 108 FP-CAD families (> or = 2 sibs having survived CAD diagnosed before age 51 (M)/56 (F)), and compared them to population controls. RESULTS: Unaffected sibs had a higher prevalence of hypertension (49% versus 24%, p<0.001), hypercholesterolemia (47% versus 34%, p=0.002), abdominal obesity (35% versus 24%, p=0.006) and smoking (39% versus 24%, p=0.001) than population controls. Offspring had a higher prevalence of hypertension (females), hypercholesterolemia and abdominal obesity than population controls. No difference was observed between spouses and controls. Compared to unaffected sibs, FP-CAD affected sibs had a similar risk factor profile, except for smoking, which was more prevalent (76% versus 39%, p=0.008). CONCLUSIONS: Hypertension, obesity and hypercholesterolemia are highly prevalent among first-degree relatives, but not spouses, of patients with FP-CAD. These persons deserve special medical attention due to their familial/genetic susceptibility to atherogenic metabolic abnormalities. In these families, smoking may be the trigger for FP-CAD.
