Interesse, ideologia & incompetência: a guerra do Iraque e o segundo consenso de Washington

Este projeto continua a avançar o programa de pesquisa que relaciona desenvolvimento econômico e democracia: pretende-se neste projeto dar um passo adiante e examinar como a democracia, uma vez consolidada como fruto do desenvolvimento capitalista, se torna ela própria um fator de desenvolvimento, particularmente quando ela deixa de ser uma mera democracia de elites para se tornar uma democracia de sociedade civil, na qual o debate público passa a ser um elemento central.

How the full opening of the capital account to highly liquid financial markets led Latin America to two and a half cycles of ‘mania, panic and crash’

Latin America has recently experienced three cycles of capital inflows, the first two ending in major financial crises. The first took place between 1973 and the 1982 ‘debt-crisis’. The second took place between the 1989 ‘Brady bonds’ agreement (and the beginning of the economic reforms and financial liberalisation that followed) and the Argentinian 2001/2002 crisis, and ended up with four major crises (as well as the 1997 one in East Asia) — Mexico (1994), Brazil (1999), and two in Argentina (1995 and 2001/2). Finally, the third inflow-cycle began in 2003 as soon as international financial markets felt reassured by the surprisingly neo-liberal orientation of President Lula’s government; this cycle intensified in 2004 with the beginning of a (purely speculative) commodity price-boom, and actually strengthened after a brief interlude following the 2008 global financial crash — and at the time of writing (mid-2011) this cycle is still unfolding, although already showing considerable signs of distress. The main aim of this paper is to analyse the financial crises resulting from this second cycle (both in LA and in East Asia) from the perspective of Keynesian/ Minskyian/ Kindlebergian financial economics. I will attempt to show that no matter how diversely these newly financially liberalised Developing Countries tried to deal with the absorption problem created by the subsequent surges of inflow (and they did follow different routes), they invariably ended up in a major crisis. As a result (and despite the insistence of mainstream analysis), these financial crises took place mostly due to factors that were intrinsic (or inherent) to the workings of over-liquid and under-regulated financial markets — and as such, they were both fully deserved and fairly predictable. Furthermore, these crises point not just to major market failures, but to a systemic market failure: evidence suggests that these crises were the spontaneous outcome of actions by utility-maximising agents, freely operating in friendly (‘light-touch’) regulated, over-liquid financial markets. That is, these crises are clear examples that financial markets can be driven by buyers who take little notice of underlying values — i.e., by investors who have incentives to interpret information in a biased fashion in a systematic way. Thus, ‘fat tails’ also occurred because under these circumstances there is a high likelihood of self-made disastrous events. In other words, markets are not always right — indeed, in the case of financial markets they can be seriously wrong as a whole. Also, as the recent collapse of ‘MF Global’ indicates, the capacity of ‘utility-maximising’ agents operating in (excessively) ‘friendly-regulated’ and over-liquid financial market to learn from previous mistakes seems rather limited.

Opening ILT blackbox: Exploring recognition-based leadership perceptions with conjoint analysis

Although research on Implicit Leadership Theories (ILT) has put great effort on determining what attributes define a leader prototype, little attention has been given to understanding the relative importance of each of these attributes in the categorization process by followers. Knowing that recognition-based leadership perceptions are the result of the match between followers’ ILTs and the perceived attributes in their actual leaders, understanding how specific prototypical leader attributes impact this impression formation process is particularly relevant. In this study, we draw upon socio-cognitive theories to explore how followers cognitively process the information about a leader’s attributes. By using Conjoint Analysis (CA), a technique that allows us to measure an individual’s trade-offs when making choices about multi-attributed options, we conducted a series of 4 studies with a total of 879 participants. Our results demonstrate that attributes’ importance for individuals’ leadership perceptions formation is rather heterogeneous, and that some attributes can enhance or spoil the importance of other prototypical attributes. Finally, by manipulating the leadership domain, we show that the weighting pattern of attributes is context dependent, as suggested by the connectionist approach to leadership categorization. Our findings also demonstrate that Conjoint Analysis can be a valuable tool for ILT research.

Chemical and microbiological changes and aerobic stability of marandu grass silages after silo opening

Esta pesquisa foi realizada com os objetivos de caracterizar a microbiologia e avaliar a estabilidade aeróbia de silagens de capim-marandu contendo polpa cítrica peletizada (PCP). A forragem colhida foi submetida aos seguintes tratamentos: silagem de capim-marandu; silagem de capim-marandu + 5% PCP e silagem do capim-marandu + 10% de PCP com base na matéria natural. As alterações químicas e microbiológicas foram feitas aos 0, 2, 4 e 6 dias após a abertura dos silos (tambores de metal com 80 cm de altura e 50 cm de diâmetro). Na avaliação da estabilidade aeróbia por meio da alteração da temperatura, 3 kg de silagem foram colocados em caixas de isopor, que foram armazenadas em câmara climática. Nos dois ensaios realizados, utilizou-se delineamento inteiramente ao acaso com cinco repetições, em esquema de parcelas subdivididas, de modo que os níveis de PCP na silagem corresponderam às parcelas e o tempo, às subparcelas. As silagens sem polpa apresentaram desenvolvimento de bacilos e enterobactérias e aumento do pH no decorrer do desabastecimento dos silos. A presença de leveduras foi detectada nas silagens contendo o aditivo e aumentou do primeiro ao sexto dia de aeração. A digestibilidade in vitro da matéria seca (DIVMS) reduziu com o aumento dos tempos de aeração. A temperatura nas silagens com 10% de PCP aumentou durante a aerobiose. Com a abertura dos silos, as silagens apresentaram-se instáveis, seja pelo desenvolvimento de bactérias seja pelo desenvolvimento de leveduras, o que reduziu seu valor nutritivo.

Acoplador e linha de lâmina unilateral e bilateral com substrato fotônico

The aim of this work is to characterize and use the characteristic parameters of the planar structures constructed with fin lines looking for their applications in devices, using PBG Photonic Band Gap photonic materials as substrate, operating in the millimeter and optic wave bands.The PBG theory will be applied for the relative permittivity attainment for the PBG photonic substrate s and p polarizations. The parameters considered in the structures characterization are the complex propagation constant and the characteristic impedance of unilateral and bilateral fin lines that were obtained by the use of the TTL Transverse Transmission Line Method, together with the Method of the Moments. The final part of this work comprises studies related to the behavior of the asymmetric unilateral fin line coupler with photonic substrate. This research opens perspectives for new works in this modern area. Numerical results are shown by means of bi-dimensional and three-dimensional graphics. Conclusions and suggestions for future works are also presented

An Anisotropic Model of Damage and Unilateral Effect for Brittle Materials

This work deals with the initial applications and formulation of an aniscitropic plastic-damage constitutive model proposed for non-linear analysis of reinforced concrete structures submitted to a loading with change of the sign. The original constitutive model is based on the fundamental hypothesis of energy equivalence between real and continuous medium following the concepts of the Continuum Damage Mechanics. The concrete is assumed as an initial elastic isotropic medium presenting anisotropy, permanent strains and bimodularity (distinct elastic responses whether traction or compression stress states prevail) induced by damage evolution. In order to take into account the bimodularity, two damage tensors governing the rigidity in tension or compression regimes are introduced. Then, some conditions are introduced in the original version of the model in order to simulate the damage unilateral effect. The three-dimensional version of the proposed model is analyzed in order to validate its formulation when compared to micromechanical theory. The one-dimensional version of the model is applied in the analyses of a reinforced concrete beam submitted to a loading with change of the sign. Despite the parametric identification problems, the initial applications show the good performance of the model.

Estudo comparativo do bloqueio combinado femoral-isquiático, por punção em sítio único, com anestesia subaracnóidea para cirurgia unilateral do membro inferior

JUSTIFICATIVA E OBJETIVOS: A raquianestesia unilateral pode apresentar vantagens em pacientes ambulatoriais. O objetivo deste trabalho foi comparar a raquianestesia unilateral com o bloqueio combinado femoral-isquiático em cirurgias ortopédicas unilaterais e ambulatoriais. MÉTODO: Sessenta pacientes foram aleatoriamente separados em dois grupos para receber 6 mg de bupivacaína hiperbárica ou hipobárica (grupo RQ) em decúbito lateral esquerdo ou 800 mg de lidocaína 1,6% com epinefrina nos nervos femoral e isquiático (grupo CFI) em decúbito dorsal. O bloqueio dos nervos foi realizado com agulha de 150 mm conectada a um neuroestimulador e inserida no ponto médio entre as duas abordagens clássicas, sendo injetados 15 mL no nervo femoral e 35 mL no nervo isquiático. Avaliados o tempo para realização dos bloqueios e sua duração. Vinte minutos após, os pacientes foram avaliados em relação aos bloqueios sensitivo e motor. RESULTADOS: O tempo para a realização da raquianestesia foi significativamente menor do que o bloqueio combinado femoral-isquiático. O bloqueio unilateral foi obtido em 90% dos pacientes no grupo RQ e 100% no grupo CFI. O tempo para recuperação do bloqueio sensitivo e motor foi significativamente maior no grupo CFI. Não houve bradicardia ou hipotensão. CONCLUSÕES: Este estudo conclui que é tecnicamente fácil realizar bloqueio anterior combinado femoral-isquiático e pode ser uma alternativa para o bloqueio unilateral do membro inferior. A raquianestesia unilateral com baixas doses de bupivacaína resultou em menor tempo para realização, menor número de tentativas e recuperação mais precoce do bloqueio combinado femoral-isquiático, porém com mesma efetividade.

Unilateral Facial Paralysis Caused by Ramsay Hunt Syndrome

The Ramsay Hunt syndrome is a rare disease caused by an infection of the geniculate ganglion by the varicella-zoster virus. The main clinical features of the syndrome are as follows: Bell palsy unilateral or bilateral, vesicular eruptions on the ears, ear pain, dizziness, preauricular swelling, tingling, tearing, loss of taste sensation, and nystagmus. We describe a 23-year-old white woman, who presented with facial paralysis on the left side of the face, pain, fever, ear pain, and swelling in the neck and auricular region on the left side. She received appropriate treatment with acyclovir, vitamin B complex, and CMP nucleus. After 30 days after presentation, the patient did not show any signs or symptoms of the syndrome. At follow-up at 1 year, she showed no relapse of the syndrome.
