Background and Aims: Calcium-containing phosphate binders have been shown to increase the progression of vascular calcification in hemodialysis patients. This is a prospective study that compares the effects of calcium acetate and sevelamer on coronary calcification (CAC) and bone histology. Methods: 101 hemodialysis patients were randomized for each phosphate binder and submitted to multislice coronary tomographies and bone biopsies at entry and 12 months. Results: The 71 patients who concluded the study had similar baseline characteristics. On follow-up, the sevelamer group had higher levels of intact parathyroid hormone (498 +/- 352 vs. 326 +/- 236 pg/ml, p = 0.017), bone alkaline phosphatase (38 +/- 24 vs. 28 +/- 15 U/l, p = 0.03) and deoxypyridinoline (135 +/- 107 vs. 89 +/- 71 nmol/l, p = 0.03) and lower LDL cholesterol (74 +/- 21 vs. 91 +/- 28 mg/dl, p = 0.015). Phosphorus (5.8 +/- 1.0 vs. 6 +/- 1.0 mg/dl, p = 0.47) and calcium (1.27 +/- 0.07 vs. 1.23 +/- 0.08 mmol/l, p = 0.68) levels did not differ between groups. CAC progression (35 vs. 24%, p = 0.94) and bone histological diagnosis at baseline and 12 months were similar in both groups. Patients of the sevelamer group with a high turnover at baseline had an increase in bone resorption (eroded surface, ES/BS = 9.0 +/- 5.9 vs. 13.1 +/- 9.5%, p = 0.05), whereas patients of both groups with low turnover at baseline had an improvement in bone formation rate (BFR/BS = 0.015 +/- 0.016 vs. 0.062 +/- 0.078, p = 0.003 for calcium and 0.017 +/- 0.016 vs. 0.071 +/- 0.084 mu m(3)/mu m(2)/day, p = 0.010 for sevelamer). Conclusions: There was no difference in CAC progression or changes in bone remodeling between the calcium and the sevelamer groups. Copyright (C) 2008 S. Karger AG, Basel

As opções de política externa do Brasil são limitadas, tendo em conta os recursos materiais superiores das grandes potências establecidas. Soft balancing envolve estratégias institucionais, tais como a formação de coalizões ou ententes diplomáticas limitadas, como BRIC, para restringir o poder das grandes potências estabelecidas. Os países BRIC tinham constado dentre os precursores mais fortes de mudança da diplomacia mundial e por sua vez se beneficiam mais destas mudanças de poder global. Dentro da ordem global modelada pelas grandes potências por meio de instituições internacionais, aqueles jogadores que operam efetivamente dentro destas como inovadores, formadores de alianças e porta-vozes, e que ao mesmo tempo conservam soberania e independência têm o potencial de influir sustancialmente os resultados de políticas futuras.

ABSTRACTThe Copula Theory was used to analyze contagion among the BRIC (Brazil, Russia, India and China) and European Union stock markets with the U.S. Equity Market. The market indexes used for the period between January 01, 2005 and February 27, 2010 are: MXBRIC (BRIC), MXEU (European Union) and MXUS (United States). This article evaluated the adequacy of the main copulas found in the financial literature using log-likelihood, Akaike information and Bayesian information criteria. This article provides a groundbreaking study in the area of contagion due to the use of conditional copulas, allowing to calculate the correlation increase between indexes with non-parametric approach. The conditional Symmetrized Joe-Clayton copula was the one that fitted better to the considered pairs of returns. Results indicate evidence of contagion effect in both markets, European Union and BRIC members, with a 5% significance level. Furthermore, there is also evidence that the contagion of U.S. financial crisis was more pronounced in the European Union than in the BRIC markets, with a 5% significance level. Therefore, stock portfolios formed by equities from the BRIC countries were able to offer greater protection during the subprime crisis. The results are aligned with recent papers that present an increase in correlation between stock markets, especially in bear markets.

The aim of this study is to investigate volatility spillover-effect and market integration between BRIC countries. Motivated by existing literature of market integration between developed and emerging markets, we will investigate market linkages using multivariate asymmetric GARCH BEKK model. The increasing globalization of the financial markets and consequent higher volatility transfer between markets makes it more important to understand market integration between BRIC countries. We investigate the stock market integration and volatility transfer between the BRIC countries form 1998 to 2007, using daily data. The empirical results show that there are international diversification benefits among Brazil, Russia, China and India. U.S. influence to these countries has been week, even though U.S. economy has been leading the global financial markets. From Finnish point of view, diversification benefits are robust but we find some correlation with Russia and China.

Based on Science, Technology & Innovation (ST&I) indicators, Brazil is a competitive and interesting country from the point of view of technological foreign investment. However, it is still incipient with regard to national investments, production of technological knowledge, inbound mobility of scientists and technology transfer to the productive sector. Among many other factors, global patent production is considered as an important indicator of innovation. Likewise, the balance between revenue and expenses obtained through royalties and licensing fees of technologies is also critical in mapping the diffusion and absorption of knowledge. The understanding of intellectual property and its strategic management brings a significant advantage to the economic and technological development of nations, especially in the field of chemistry, which greatly contributes to biotechnology, new materials and microelectronics - three fundamental areas for innovation in developed countries. Therefore, this article aims to map out competencies in chemistry in Brazil and evaluate science, technology and innovation indicators in the country, comparing this dynamic to the one of other BRIC members (Russia, India and China). Chemistry is the fourth biggest field of interest in Brazil based on the number of researchers registered at the governmental platform for researchers, Plataforma Lattes/CNPq, and is preceded by education, medicine and agronomy. The majority of research groups are registered in the area of materials, followed by macromolecules and polymers, pharmaceutical products and basic materials chemistry. These groups represent approximately 77% of research groups analyzed, therefore, indicating a tendency in the country. The analyses of patents in different sub-areas of chemistry reveal that non-residents file most deposits in the country, a probable reflection of the low internal intellectual property culture. Pharmaceutics and Fine Chemistry are prominent areas in the country, in line with the global trend. Among BRIC countries, China has the highest number of patents and of requests for protection in international offices. On the other hand, Brazil has the lowest number of chemical patents published at USPTO, EPO and JPO. An analysis of the transfer of technology data indicates an increase in this activity in various sub-areas of chemistry in the country. Despite the great efforts made by the country to consolidate its national innovation system, more needs to be done to put Brazil in a competitive position. In a globalized world dominated by large players, Brazil needs a lot of progress on ownership and generation of chemistry technologies to strengthen its national sovereignty. It is essential to strengthen chemical research at all levels, from elementary school to university, as an inexhaustible source of knowledge and technology that, when properly protected, may generate real public achievement and social return.

The aim of this thesis is to examine stock returns as predictive indicators to macroeconomic variables in BRIC-countries, Japan, USA and euro area. We picked to represent macroeconomic variables interest rate, inflation, currency, gross domestic product and industrial production. For the beginning we examined previous studies and theory about the subject. Hypothesis of this thesis were derived from the previous studies. To conduct the results we used tests such augmented Dickey-Fuller, Engle-Granger co-integration, Granger causality and lagged distribution model. According to results stock returns do predictive macroeconomic variables and specifically changes of GDP and industrial production. There were few evidences of stock returns predictive power of inflation.

The objective of this paper is to analyze the relationship between exchange rate regime, capital account convertibility and economic growth in 1990-2007 period within the emerging countries that constitute what has been called BRIC - Brazil, Russia, India and China. Our hypothesis is that economic performance of these countries is the result, at least partially, of the quality of the macroeconomic policy management adopted in each country, in which exchange rate policy, capital account convertibility and the degree of external vulnerability plays a key role.

El siguiente documento da a conocer el comportamiento de la Inversión Extranjera Directa (IED) de los países denominados BRIC (Brasil, Rusia, India y China) en Colombia. De acuerdo a lo anterior, en el presente trabajo, se realizó un análisis general de la IED entrante en el país suramericano que buscaba establecer los principales inversores; además de determinar los sectores más atractivos. Posteriormente, se observó la magnitud de la inversión que realizan los países BRIC en Colombia y en el mundo, con el fin de efectuar una comparación que permitiera determinar que tan significativa es la inversión que se realiza en el Estado Colombiano frente a la que es efectuada por estas naciones a nivel global. Igualmente, se consideró las industrias a las que la IED está dirigida, el grado de beneficio que representa para la población y si existe la posibilidad de enfocarla hacia otros sectores estratégicos o si se recomienda encauzarla hacia aquellos que hoy en día son el principal foco de inversión.

Esta dissertação procurou identificar o papel dos governos na internacionalização produtiva de empresas dos países BRIC. Por meio de uma análise comparativa do comportamento dos investimentos diretos no exterior (IDE) destes países e dos mecanismos existentes de suporte à internacionalização das empresas, foi possível identificar as diferentes maneiras de envolvimento desses governos na internacionalização produtiva de suas empresas e apontar lacunas de políticas públicas nestes países. Destarte, esta dissertação contribui à compreensão inicial sobre como e por que os governos destes países têm promovido o desenvolvimento de multinacionais. A rápida ascensão das multinacionais dos países BRIC é um fenômeno recente. Apesar de terem investido no exterior anteriormente, apenas a partir do início dos anos 2000 que o IDE de empresas destes países tornou-se significativo. Desde então, as multinacionais dos países BRIC estão se tornando importantes players em diversas indústrias, adquirindo competidores de países desenvolvidos e em desenvolvimento, e redesenhando a concorrência em muitas indústrias globais. Neste processo, os governos dos países BRIC têm desempenhado um papel importante. Até o início dos anos 1990, o IDE era restringido porque era associado a efeitos negativos sobre as economias domésticas (como por exemplo, à redução de investimentos no país de origem, à exportação de empregos, e a problemas na balança de pagamentos). Desde o início dos anos 2000, entretanto, os governos dos países BRIC mudaram de percepção e passaram a adotar políticas favoráveis à internacionalização produtiva de empresas domésticas. Eles perceberam a importância da internacionalização para a manutenção ou expansão da competitividade das empresas domésticas em um mundo globalizado. A China, e em menor grau a Índia, estão um passo adiante, tendo já posto em prática um conjunto de instrumentos específicos que facilitam a internacionalização de suas empresas. O Brasil e a Rússia ainda têm de tomar novas medidas para criar um ambiente propício para que suas empresas possam mais facilmente explorar as vantagens da expansão global.

This Master s Thesis aims to use the theoretical models of growth with restricted balance of payments, specifically Kaldor (1970) and Thirlwall (1979) models, to analyze the behavior and the pattern of specialization of Brazilian exports and imports in the last years. It is observed that, in some periods, the pattern of specialization has contributed in restricting long-term growth of the Brazilian economy. It has been hypothesized that overall this is due to lack of structural transformation policies. To achieve this goal, it analyzed the performance of Brazilian exports and imports disaggregating them according to their technological content. The basis for comparison was a group of countries to which Brazil is inserted in, the BRIC. In this regard, the work is a comparative analysis by using descriptive statistics. It is concluded that the low rate of GDP growth experienced by Brazil since the 1980s can be explained in part by the decoupling of the Brazilian National Innovation System (NIS) and the Brazilian productive structure. This would be reducing the income elasticity of exports and raising imports, causing a pattern of specialization intensive primary commodities and labor and low-skill labor
