On the distributive impact of unconventional monetary policy

Logo após à crise financeira de 2007-08 o Federal Reserve interveio para tentar controlar a recessão. No entanto, ele não apenas baixou os juros, como também adotou políticas não-convencionais, incluindo o empréstimo direto para empresas em mercados de crédito de alto nível. Estas novas medidas foram controversas e alguns opositores protestaram porque elas estariam ajudando disproporcionalmente aquelas pessoas ligadas ao sistema financeiro que já eram ricas. Nós utilizamos um modelo DSGE para a análise de políticas monetária não convencional e introduzimos dois tipos distintos de agentes, capitalistas e trabalhadores, para investigar o seu impacto distributivo. Nós encontramos que a política de crédito to Fed foi bem sucedida no mercado de trabalho, o que ajuda mais os trabalhadores, e introduziu um novo competidor no mercado bancário, o governo, o que prejudica mais os capitalistas. Logo, nós encontramos que a política de crédito diminuiu a desigualdade nos EUA.

Determinação de parâmetros de qualidade para formas farmacêuticas homeopáticas

All medicine, whether allopathic or homeopathic, must go through strict quality control, which must ratify their characteristics throughout the period of validity. During the time of preparation and storage, solutions of the drugs are in permanent contact with packaging materials that can release undesirable substances to the solution. Several factors may influence the release of packing materials, and factorial design (FD) is a useful tool for analyzing the phenomenon. The aim of this study was the determination of quality parameters for Homeopathic solid (globules) and liquid (drops) dosage forms. It was carried out analysis in homeopathic globules for weight variation, mechanical strength, and moisture content uniformity. For liquid preparations, standard solutions were prepared from natural rubber bulbs, which were subjected to exhaustive extraction with two ethanol solutions (30 and 70%) in the ultrasonic bath for 20 minutes at 25°C and 50°C in three successive cycles. Studies of transfer have been made within five days, by spectrophotometric analysis in the UV region at 312 nm with λmáx and 323 nm for samples in 70% ethanol and 30% respectively. PH values were analyzed. We also conducted two FD studies, where the first, the three-level variables were solvent (chloroform, ethanol and nhexane), sample mass (30, 60 and 90mg), particle size (large disk, small disk and powder sample). In the second study, the solvent level variables were different ethanolic degrees (EtOH 30%, 70% and pure). The percentage of lending in the solutions was 5.5%, 12.4%, 24.2% and 41% of the total estimated in the reference solution. The values of rate constants of transfer were determined in the order of 0.0134 days-1 and 0.0232 days-1 in absorbance values, the solutions in ethanol at 30% and 70% respectively. These results suggest that the speed of transfer of materials from rubber is affected both by the nature of the vehicle as by the temperature

Medicina filosófica: as relações entre medicina e filosofia na Grécia antiga e em Kant

This work deals with the relationship between medicine and philosophy, which has existed since Antiquity, and will also be discussed here from Kant s perspective. It presents the historical context formed by reciprocal influences of common notions regarding health/disease, balance/justice, and just measure, which are present in the medical discourse as much as in the philosophical one. It considers that Hippocratic medicine emerges from concerns about dietetics, thus creating the link between philosophy and medicine, which is important for our analysis on Kant s contributions to Hippocratic legacy. Taking into account these considerations, the work distinguishes between two aspects which are associated within the dietetics presented by Kant in his work The conflict of the faculties, studied here in the light of his Doctrine of virtue, particularly the duties to oneself in regard the care of one s body and the teleological conception. In this sense, the work indicates the role of Kantian thinking not only to enrich medical dietetics, by lending to it moral value, but also to enrich philosophy by highlighting its therapeutic effects

Distribuição dos recursos do FNE para o setor turístico entre os estados nordestinos, no período de 1998/2004

The work aims to analyze the criteria that supported the geographic distribution of credit with FNE funds for the private tourism sector in the period 1998-2004 the Northeast, which is the maturing of a significant part of investments in the region I PRODETUR . The working hypothesis is that the credit allocation for the tourism industry, with FNE funds among the Northeastern states during the period analyzed broke with the trend towards concentration of credit in the richer economies of the region. The investigation concluded that there is enough evidence to enhance the degree of confidence in that hypothesis. However, the allocation criteria do not only benefited the poorest economies, nor directed lending while building on the weight that the tourism sector held in state economies

Mutational analyses of human eIF5A-1-identification of amino acid residues critical for eIF5A activity and hypusine modification

The eukaryotic translation initiation factor 5A (eIF5A) is the only protein that contains hypusine [N-epsilon-(4-amino-2-hydroxybutyl)lysine], which is required for its activity. Hypusine is formed by post-translational modification of one specific lysine (Lys50 for human eIF5A) by deoxyhypusine synthase and deoxyhypusine hydroxylase. To investigate the features of eIF5A required for its activity, we generated 49 mutations in human eIF5A-1, with a single amino acid substitution at the highly conserved residues or with N-terminal or C-terminal truncations, and tested mutant proteins in complementing the growth of a Saccharomyces cerevisiae eIF5A null strain. Growth-supporting activity was abolished in only a few mutant eIF5As (K47D, G49A, K50A, K50D, K50I, K50R, G52A and K55A), with substitutions at or near the hypusine modification site or with truncation of 21 amino acids from either the N-terminus or C-terminus. The inactivity of the Lys50 substitution proteins is obviously due to lack of deoxyhypusine modification. In contrast, K47D and G49A were effective substrates for deoxyhypusine synthase, yet failed to support growth, suggesting critical roles of Lys47 and Gly49 in eIF5A activity, possibly in its interaction with effector(s). By use of a UBHY-R strain harboring genetically engineered unstable eIF5A, we present evidence for the primary function of eIF5A in protein synthesis. When selected eIF5A mutant proteins were tested for their activity in protein synthesis, a close correlation was observed between their ability to enhance protein synthesis and growth, lending further support for a central role of eIF5A in translation.
