The impacts of TTIP on Brazil

The objective of this project is to analyze the effects for Brazil of the conclusion of TTIP. This is approached under different hypotheses: considering the effects on Brazil of a TTIP with the reduction of only tariff barriers between US and EU; introducing a partial reduction of non-tariff barriers; and, at last, with a complete reduction of these barriers. To finalize, an audacious alternative is assumed: a hypothetical participation of Brazil in the TTIP under a partial reduction of agricultural tariffs by the US and EU markets, and under a full liberalization of their agricultural markets. The methodology used to estimate non-tariff barriers was presented in the Ecorys Project (2009) developed by Berden e Francois to the European Commission.

Exchange rate misalignments and international trade policy: impacts on tariffs

The debate on “exchange wars and trade wars” is raising the attention of experts on international trade and economics. The main purpose of this paper is to analyze the impacts of exchange rate misalignments on one of the most traditional trade policy instruments – tariffs, as defined by the WTO – World Trade Organization. It is divided into three sections: the first one examines the effects of exchange rate variations on tariffs and its consequences for the multilateral trade system; the second explains the methodology used to determine exchange rate misalignments and also presents its results for Brazil, US and China; and the third summarizes the methodology applied to calculate the impacts of exchange rate misalignments on the level of tariff protection through an exercise of “misalignment tariffication”

EU-Mercosur trade relations: impacts of exchange rate misalignments on tariffs

The issue of “trade and exchange rate misalignments” is being discussed at the G20, IMF and WTO, following an initiative by Brazil. The main purpose of this paper is to apply the methodology developed by the authors to exam the impacts of misalignment on tariffs in order to analyse the impacts of misalignments on the trade relations between two customs unions – the EU and Mercosur, as well as to explain how tariff barriers are affected. It is divided into several sections: the first summarises the debate on exchange rates at the WTO; the second explains the methodology used to determine exchange rate misalignments; the third and fourth summarises the methodology applied to calculate the impacts of exchange rate misalignments on the level of tariff protection through an exercise of ‘misalignment tariffication’; the fifth reviews the effects of exchange rate misalignments on tariffs and its consequences for the trade negotiations between the two areas; and the last concludes and suggests a way to move the debate forward in the context of regional arrangements

Financial governance: the Brazilian experience on prudential regulation and its impacts on the effects of the 2008 financial crisis

The Brazilian economy was severely hit by the 2008 crisis. In the beginning of the crisis, the vast majorities of the economic agents and authorities thought that Brazil could face some sort of decoupling since some macroeconomic fundamentals were very good. What we saw, however, was that the Brazilian economy was not decoupled, and expectations faced a huge deterioration soon after the bankruptcy of Lehman Brothers in September 15th. Two aspects regarding the impact of crisis in Brazil, however, deserve a great deal of attention: (a) although deep, the impact did not last for a long time. Actually, the GDP growth experienced a good recovery in the second quarter of 2009, showing that the health of the Brazilian economy was good; (b) the Brazilian banking system performed very well during the crisis, although we cannot say the system was not in danger in the worst time of the crisis. In spite of the confidence crisis faced by the banking system 1, it showed a great deal of resilience. In this aspect, we argue that the restructure faced by the banking system in the aftermath of the Real Plan, as well as the development of a solid supervision regulation helped a lot the system to avoid the systemic crisis that was an open possibility to the Brazilian banking system in the end of 2008. These notes, thus, discusse why the Brazilian banking system performed pretty well in the 2008 financial crisis and how the Brazilian banking (and prudential) regulation can be taken as responsible for this good performance. More specifically, the paper back to the middle of the 1990s, when the Real Plan was implemented, in order to understand the role played by the restructuring of the Brazilian financial system in helping to pave the way to the great resilience experienced by the Brazilian banking system during the 2008 crisis. More specifically, the prudential regulation that was implemented in Brazil in the aftermath of the Real Plan seems to play a decisive role in the resilience of the system nowadays.

Natural disasters and their impacts on supply chains

This research aimed to understand how Brazilian organizations, located in areas affected by natural disasters were impacted in their operations and the impacts to their whole supply chain. Based on documentary analysis, the study identified the major events that happened in Brazil between 2003 and 2012 and the most affected supply chains, as well as key players during the disaster and the greatest impacts on economic activities. The results suggest that natural disasters are still not considered in the risk management by companies, despite the effects on their activities

Impacts of limestone and nitrogen top dressing application on the potassium content in the soil profile and marandu-grass leaf concentration

Objetivou-se avaliar os efeitos de nitrogênio (0, 100, 200, 300 e 400 kg/ha.ano), com ou sem aplicação de calcário dolomítico em cobertura, sobre o teor de potássio (K) do solo nas profundidades de 0 a 5; 5 a 10; e 10 a 20 cm e a concentração de potássio na planta. O experimento foi realizado em Latossolo Vermelho distroférrico de relevo suavemente ondulado, disposto em esquema fatorial 5 × 2, em blocos casualizados, com quatro repetições. A adubação nitrogenada promoveu aumento linear na concentração de potássio na planta e no teor desse mineral na camada de 0 a 5 cm do solo. Ocorreu efeito de inibição competitiva entre a absorção de potássio e cálcio e entre potássio e magnésio. Embora uma fração significativa de potássio retorne à camada superficial do solo pelo resíduo de forragem, em decorrência da maior produção de massa, o aumento da concentração de potássio na planta nas mais altas doses de nitrogênio comprova a importância do suprimento de potássio para a planta, por intensificar a massa de forragem.

Viable human buccal mucosa cells do not yield typical nucleoids: Impacts on the single-cell gel electrophoresis/comet assay

Buccal mucosa (BM) cells have been used in human biomonitoring studies for detecting DNA adducts and chromosomal damage in an epithelial cell population. In the present study, we have investigated if human BM cells are suitable for use in the single-cell gel electrophoresis (SCGE)/Comet assay as an approach for estimating the exposure of epithelial cells to DNA-damaging agents. Our results indicate that only a few cells from BM cell samples yield comets that can be analyzed by current methods, and that the yield of cells with comets is independent of the percentage of viable BM cells in the sample. Data generated after enzymatic enrichment of viable cells and immunomagnetic separation of epithelial cells suggest that most of the BM cells that do form comets are probably leukocytes. Moreover, by reevaluating specific cells after running the Comet assay, we found that viable epithelial BM cells give rise to atypical comets that are not included in the analysis. Comparing DNA migration patterns between small groups of smokers and nonsmokers indicated that long-term smoking had no effect on the subpopulation of cells that yield typical comets. Our results indicate that the SCGE assay, as it is commonly performed, may not be useful for genotoxicity monitoring in human epithelial BM cells.

Mutagenic and carcinogenic potential of a textile azo dye processing plant effluent that impacts a drinking water source

Recently a textile azo dye processing plant effluent was identified as one of the sources of mutagenic activity detected in the Cristais River, a drinking water source in Brazil [G.A. Umbuzeiro, D.A. Roubicek, C.M. Rech, M.I.Z. Sato, L.D. Claxton, Investigating the sources of the mutagenic activity found in a river using the Salmonella assay and different water extraction procedures, Chemosphere 54 (2004) 1589-1597]. Besides presenting high mutagenic activity in the Salmonella/microsome assay, the mutagenic nitro-aminoazobenzenes dyes CI Disperse Blue 373, Cl Disperse Violet 93, and CI Disperse Orange 37 [G.A. Umbuzeiro, H.S. Freeman, S.H. Warren, D.P Oliveira, Y. Terao, T. Watanabe, L.D. Claxton, the contribution of azo dyes in the mutagenic activity of the Cristais river, Chemosphere 60 (2005) 55-64] as well as benzidine, a known carcinogenic compound [T.M. Mazzo, A.A. Saczk, G.A. Umbuzeiro, M.V.B. Zanoni, Analysis of aromatic amines in surface waters receiving wastewater from textile industry by liquid chromatographic with eletrochemical detection, Anal. Lett., in press] were found in this effluent. After similar to 6 km from the discharge of this effluent, a drinking water treatment plant treats and distributes the water to a population of approximate 60,000. As shown previously, the mutagens in the DWTP intake water are not completely removed by the treatment. The water used for human consumption presented mutagenic activity related to nitro-aromatics and aromatic amines compounds probably derived from the cited textile processing plant effluent discharge [G.A. Umbuzeiro, D.A. Roubicek, C.M. Rech, M.I.Z.. Sato, L.D. Claxton, Investigating the sources of the mutagenic activity found in a river using the Salmonella assay and different water extraction procedures, Chemosphere 54 (2004) 1589-1597; G.A. Umbuzeiro, H.S. Freeman, S.H. Warren, D.P. Oliveira, Y. Terao, T. Watanabe, L.D. Claxton, the contribution of azo dyes in the multagenic activity of the Cristais river, Chemosphere 60 (2005) 55-64]. Therefore, it is important to evaluate the possible risks involved in the human consumption of this contaminated water. With that objective, one sample of the cited industrial effluent was tested for carcinogenicity in the aberrant crypt foci medium-term assay in colon of Wistar rats. The rats received the effluent in natura through drinking water at concentrations of 0.1%, 1%, and 10%. The effluent mutagenicity was also confirmed in the Salmonella/microsome assay with the strains TA98 and YG1041. There was an increased number of preneoplastic lesions in the colon of rats exposed to concentrations of 1% and 10% of the effluent, and a positive response for both Salmonella strains tested. These results indicate that the discharge of the effluent should be avoided in waters used for human consumption and show the sensitivity of the ACF crypt foci assay as an important tool to evaluate the carcinogenic potential of environmental complex mixtures.

Evaluating distributed generation impacts with a multiobjective index

Evaluating the technical impacts associated with connecting distributed generation to distribution networks is a complex activity requiring a wide range of network operational and security effects to be qualified and quantified. One means of dealing with such complexity is through the use of indices that indicate the benefit or otherwise of connections at a given location and which could be used to shape the nature of the contract between the utility and distributed generator. This paper presents a multiobjective performance index for distribution networks with distributed generation which considers a wide range of technical issues. Distributed generation is extensively located and sized within the IEEE-34 test feeder, wherein the multiobjective performance index is computed for each configuration. The results are presented and discussed.
