The Brazilian monetary and fiscal policies from 2011 to 2017: conventions and crisis

Post Keynesians define conventions as creeds shared by individuals who use them to ground their expectations. Economic policymaking plays a major role in the development of conventions. Thus, this article analyses Brazil’s fiscal and monetary policies over 2011-2017. First, it shows how the monetary policy over 2011-2014 wasted the opportunity to establish a lower base rate in Brazil, what we call ‘the mistakes of the past’. Second, it argues that the austerity policy implemented after 2015 formed the convention that public investments are not needed to boost private investments; this is what we call ‘the loss of future opportunities’

New insights into the distribution and conservation status of the Golden-White Tassel-Ear Marmoset Mico chrysoleucos (Primates, Callitrichidae)

Among the 13 Mico species recognized by the IUCN Red List of Threatened Species, six are listed as "Data Deficient". The geographic range of most of the Mico species has been estimated from only a few records. We report new localities and the geographic extension of Mico chrysoleucos. In addition, we confirmed the presence of the species in two distinct protected areas. We modeled the habitat suitability of M. chrysoleucos using the maximum entropy method and including new records obtained by the authors in the state of Amazonas, Brazil. From the total area of occurrence calculated for the species, 22.8% is covered by protected areas and indigenous lands. The annual mean deforestation rate estimated between 2000 and 2015 was 2.95%, and the total area deforested by 2015 was 3354 km2 or 8.6% of the total distribution limits of the species. The habitat lost between 2000 and 2015 was 3.2% (1131 km2 ) of the total potential distribution, while the habitat loss area legally protected was 31 km2, and the habitat loss in settlements was equal to 691 km2. Our results extend the geographic distribution of the species about 100 km farther south, with the Maracanã River being a possible geographic barrier for the species. The significantly low rate of habitat loss inside protected areas and indigenous land, when compared to unprotected areas, points out the importance of these areas to M. chrysoleucos conservation. The species is relatively wide-ranging, legally protected, and resilient to regional anthropic threats. However, the hydroelectric schemes and the improvement of the road system in southern Amazonia pose an imminent threat to the species

Oxpentifylline versus placebo in the treatment of erythropoietin-resistant anaemia: a randomized controlled trial

Background: The main hypothesis of this study is that Oxpentifylline administration will effectively treat erythropoietin-or darbepoietin-resistant anaemia in chronic kidney disease patients

Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

This paper presents measurements of the $W^+ \rightarrow \mu^+\nu$ and $W^- \rightarrow \mu^-\nu$ cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.

Search for chargino-neutralino production with mass splittings near the electroweak scale in three-lepton final states in √s=13 TeV pp collisions with the ATLAS detector

A search for supersymmetry through the pair production of electroweakinos with mass splittings near the electroweak scale and decaying via on-shell W and Z bosons is presented for a three-lepton final state. The analyzed proton-proton collision data taken at a center-of-mass energy of √s=13  TeV were collected between 2015 and 2018 by the ATLAS experiment at the Large Hadron Collider, corresponding to an integrated luminosity of 139  fb−1. A search, emulating the recursive jigsaw reconstruction technique with easily reproducible laboratory-frame variables, is performed. The two excesses observed in the 2015–2016 data recursive jigsaw analysis in the low-mass three-lepton phase space are reproduced. Results with the full data set are in agreement with the Standard Model expectations. They are interpreted to set exclusion limits at the 95% confidence level on simplified models of chargino-neutralino pair production for masses up to 345 GeV

Abundância e sazonalidade de cigarrinhas (Hemiptera, Cicadellidae, Cicadellinae) em vegetação herbácea de pomar de laranja doce, no município de Montenegro, Estado do Rio Grande do Sul, Brasil.

O presente estudo teve por objetivo conhecer a flutuação populacional e a constância de cicadelíneos presentes na vegetação herbácea de um pomar de laranja doce (Citrus sinensis (L.) Osbeck), variedade Valência, em Montenegro, RS. O levantamento foi realizado com a metodologia da rede-de-varredura, tendo início em fevereiro de 2001 e finalizando-se em janeiro de 2002. Mensalmente foram coletadas dez amostras, sendo cada uma destas composta por 50 golpes de rede em movimento de avanço sobre a vegetação herbácea e cultura intercalar nas entrelinhas do pomar (n = 500 golpes/ocasião de coleta). No total foram coletados 928 cicadelíneos,pertencentes a nove espécies: Bucephalogonia xanthophis (Berg, 1879), Diedrocephala variegata(Fabricius, 1775), Hortensia similis(Walker, 1851), Macugonalia leucomelas (Walker, 1851), Parathona gratiosa (Blanchard, 1840), Plesiommata corniculata Young,1977, Sibovia sagata (Signoret, 1854), Sonesimia grossa (Signoret, 1854) e Tapajosa rubromarginata (Signoret, 1855). O período de maior abundância da comunidade de cicadelíneos foi durante a primavera e o verão. Hortensia similis e M. leucomelas foram as únicas espécies consideradas constantes durante o levantamento. A menor abundância dos cicadelíneos em abril e dezembro provavelmente devese a efeitos causados por fatores abióticos (pluviosidade) e aqueles relativos à estrutura da vegetação (altura das plantas) sobre a comunidade
