Rising Brazil: Implications for the United States

Foreign policy commentator Matias Spektor explains that "Brazil and the US are not natural allies — shared interests on their own do not automatically produce alliances." That is why "A working partnership, if it is to exist at all, must be engineered."

A influência do processo de escolha dos ministros da Suprema Corte na judicialização da política: uma análise empírica do procedimento da sabatina dos indicados para o Supremo Tribunal Federal

No presente trabalho discorremos sobre o fenômeno que o mundo tem testemunhado nas últimas décadas, a judicialização da política, em que as cortes têm, cada vez mais, fortalecido o seu poder. Nesse novo cenário, a judicialização vem sendo acompanhada pelo constitucionalismo e pelo “judicial review”. As abordagens teóricas sobre o tema, por sua vez, não estão aptas a servir como modelo de justificativa para toda e qualquer judicialização, mas cada uma delas serve para explicar de que maneira ela vem acontecendo em um determinado país. Aqui no Brasil, um importante termo para designar tal ascensão do Judiciário é conhecido como supremocracia e uma das abordagens teóricas relaciona-se justamente a sua origem, qual seja, ao processo de entrada dos Ministros na mais alta corte, o STF, por meio do processo de sabatina, realizada pela Comissão de Constituição, Justiça e Cidadania. É na análise desse processo empírico que se detém o presente estudo, a fim de verificar a dinâmica política e jurídica do recrutamento dos Ministros para a nossa corte superior.

Bright minds, big rent: gentrification and the rising returns to skill

In 1980, housing prices in the main US cities rose with distance to the city center. By 2010, that relationship had reversed. We propose that this development can be traced to greater labor supply of high-income households through reduced tolerance for commuting. In a tract-level data set covering the 27 largest US cities, years 1980-2010, we employ a city-level Bartik demand shifter for skilled labor and find support for our hypothesis: full-time skilled workers favor proximity to the city center and their increased presence can account for the observed price changes, notably the rising price premium commanded by centrality.

Rising Publication Delays Inflate Journal Impact Factors

Journal impact factors have become an important criterion to judge the quality of scientific publications over the years, influencing the evaluation of institutions and individual researchers worldwide. However, they are also subject to a number of criticisms. Here we point out that the calculation of a journal’s impact factor is mainly based on the date of publication of its articles in print form, despite the fact that most journals now make their articles available online before that date. We analyze 61 neuroscience journals and show that delays between online and print publication of articles increased steadily over the last decade. Importantly, such a practice varies widely among journals, as some of them have no delays, while for others this period is longer than a year. Using a modified impact factor based on online rather than print publication dates, we demonstrate that online-to-print delays can artificially raise a journal’s impact factor, and that this inflation is greater for longer publication lags. We also show that correcting the effect of publication delay on impact factors changes journal rankings based on this metric. We thus suggest that indexing of articles in citation databases and calculation of citation metrics should be based on the date of an article’s online appearance, rather than on that of its publication in print.

Multidimensional polynomial powers of sigmoid (PPS) Wavelet neural networks

Wavelet functions have been used as the activation function in feedforward neural networks. An abundance of R&D has been produced on wavelet neural network area. Some successful algorithms and applications in wavelet neural network have been developed and reported in the literature. However, most of the aforementioned reports impose many restrictions in the classical backpropagation algorithm, such as low dimensionality, tensor product of wavelets, parameters initialization, and, in general, the output is one dimensional, etc. In order to remove some of these restrictions, a family of polynomial wavelets generated from powers of sigmoid functions is presented. We described how a multidimensional wavelet neural networks based on these functions can be constructed, trained and applied in pattern recognition tasks. As an example of application for the method proposed, it is studied the exclusive-or (XOR) problem.

Human face verification based on multidimensional Polynomial Powers of Sigmoid (PPS)

In this paper, we described how a multidimensional wavelet neural networks based on Polynomial Powers of Sigmoid (PPS) can be constructed, trained and applied in image processing tasks. In this sense, a novel and uniform framework for face verification is presented. The framework is based on a family of PPS wavelets,generated from linear combination of the sigmoid functions, and can be considered appearance based in that features are extracted from the face image. The feature vectors are then subjected to subspace projection of PPS-wavelet. The design of PPS-wavelet neural networks is also discussed, which is seldom reported in the literature. The Stirling Universitys face database were used to generate the results. Our method has achieved 92 % of correct detection and 5 % of false detection rate on the database.

Synthesis and thermal characterization of luminescent powers of terbium(III) with mixed ligands

This work deals with the synthesis and thermal decomposition of complexes of general formula: Ln(beta-dik)(3)L (where Ln=Tb(+3), beta-dik=4,4,4-trifluoro-1-phenyl-1,3butanedione(btfa) and L=1,10-fenantroline(phen) or 2,2-bipiridine(bipy). The powders were characterized by melting point, FTIR spectroscopy, LTV-visible, elemental analysis, scanning differential calorimeter(DSC) and thermogravimetry(TG). The TG/DSC curves were obtained simultaneously in a system DSC-TGA, under nitrogen atmosphere. The experimental conditions were: 0.83 ml.s(-1) carrier gas flow, 2.0 +/- 0.5 mg samples and 10 degrees C.min(-1) heating rate. The CHN elemental analysis of the Tb(btfa)(3)bipy and Tb(btfa)(3)phen complexes, are in good agreement with the expected values. The IR spectra evinced that the metal ion is coordinated to the ligands via C=O and C-N groups. The TG/DTG/DSC curves of the complexes show that they decompose before melting. The profiles of the thermal decomposition of the Tb(btfa)3phen and Tb(btfa)3bipy showed six and five decomposition stages, respectively. Our data suggests that the thermal stability of the complexes under investigation followed the order: Tb(btfa)(3)phen < Tb(btfa)(3)bipy.

Shipping costs: a rising challenge to the region's competitive development

This issue of the FAL Bulletin examines the impact of shipping costs on the exports of five Latin American and Caribbean countries by analysing the difference between the unit value of goods at the port of origin and at the port of destination, in three of the region's main external markets.

Rising concentration in Asia-Latin American value chains: Can small firms turn the tide?

Dynamic Asia has overtaken the European Union as Latin America and the Caribbean’s second largest export market, after the United States. However, the region’s exports to Asia remain concentrated in few commodities involving a small number of large firms. This book explores the present and future scope for the participation of small and medium-sized enterprises (SMEs) in biregional trade and value chains and the measures that can be taken to make those chains more inclusive and sustainable. SMEs have a low direct presence in the region’s export flows and their participation in the supplier networks of multinational companies is weak. This volume reviews several supplier development programmes (SDPs) adopted in various countries in Asia and Latin America to increase SME linkages with multinational firms. These programmes, many of which are public-private initiatives, aim to boost SME productivity and enhance their participation in value chains.

Emerging powers, humanitarian assistance and foreign policy: the case of Brazil during the earthquake crisis in Haiti

During the management of the crisis after the earthquake occurred in Haiti in 12 January 2010, Brazil played an important role on the efforts of humanitarian assistance. Based on bibliography and documents the paper presents the role played by Brazil with the focus on the humanitarian assistance as part of country’ foreign policy as an emerging power to increase the presence into the international system. To achieve this goal the article presents some considerations about emerging powers, foreign policy and theoretical concepts about humanitarian assistance and international relations, the extension of the earthquake in Haiti and the actions performed by Brazil during the response phase of the crisis management.
