O químico e naturalista luso-brasileiro Alexandre Antonio Vandelli

Alexandre Vandelli was the heir of two illustrious scientific traditions in the Luso-Brazilian world of the late eighteenth and early nineteenth centuries, that of his father, the celebrated Italian-Portuguese naturalist and chemist Domingos (Domenico) Vandelli, and that of his father-in-law, that protean figure in several scientific specialties as well as in politics, José Bonifácio de Andrada e Silva, who in later life was of paramount importance in the process of Brazilian independence from Portugal. The younger Vandelli followed their footsteps but soon engaged in a multiple career, at first in Portugal and later in Brazil, of which little is known and is here presented for the first time.

How effective is dog culling in controlling zoonotic visceral leishmaniasis? a critical evaluation of the science, politics and ethics behind this public health policy

INTRODUCTION: Zoonotic kala-azar, a lethal disease caused by protozoa of the genus Leishmania is considered out of control in parts of the world, particularly in Brazil, where transmission has spread to cities throughout most of the territory and mortality presents an increasing trend. Although a highly debatable measure, the Brazilian government regularly culls seropositive dogs to control the disease. Since control is failing, critical analysis concerning the actions focused on the canine reservoir was conducted. METHODS: In a review of the literature, a historical perspective focusing mainly on comparisons between the successful Chinese and Soviet strategies and the Brazilian approach is presented. In addition, analyses of the principal studies regarding the role of dogs as risk factors to humans and of the main intervention studies regarding the efficacy of the dog killing strategy were undertaken. Brazilian political reaction to a recently published systematic review that concluded that the dog culling program lacked efficiency and its effect on public policy were also reviewed. RESULTS: No firm evidence of the risk conferred by the presence of dogs to humans was verified; on the contrary, a lack of scientific support for the policy of killing dogs was confirmed. A bias for distorting scientific data towards maintaining the policy of culling animals was observed. CONCLUSIONS: Since there is no evidence that dog culling diminishes visceral leishmaniasis transmission, it should be abandoned as a control measure. Ethical considerations have been raised regarding distorting scientific results and the killing of animals despite minimal or absent scientific evidence

The concept of emerging power in international politics and economy

ABSTRACT This paper aims to analyze the concept of emerging power established to the understanding of international affairs. The work observes that the use of the lexicon emerging - regarding to markets, countries or powers - as qualifier for a range of international relations phenomena became a constituent part of the matter. In spite of that, the empirical denotation of the predicate is ahead of the amount of efforts on its theoretical contextualization. Our methodological hypothesis is that the rational denial of the concepts prevailing connotative spectrum by acknowledging the embedded wisdom about cognate phenomena synthesizes a theoretical framework on its accurate use.

Razão e democracia: uso público da razão e política deliberativa em Habermas[ign] [title language="en"]Reason and democracy[ign]: [subtitle]Public use of reason and deliberative politics in Habermas

O objetivo do artigo é examinar como Habermas, orientado pela intuição normativa do uso público da razão, reconstrói uma concepção procedimental de democracia deliberativa, que, sem desconsiderar da dimensão estratégica e instrumental da esfera pública e da política, reformula a dimensão epistêmica da democracia: a aceitabilidade racional dos acordos políticos. Inicialmente, apresento brevemente a análise sociológica e histórica do conceito de esfera pública crítica, realizada em Mudança Estrutural da Esfera Pública (1962), para, em seguida, expor duas linhas de argumentação sobre o conceito de esfera pública e de política deliberativa, em Direito e Democracia (1992): a que se refere ao princípio de legitimação baseado na razão pública como uma reconstrução intersubjetiva e política do conceito kantiano de autonomia; e a que concerne aos aspectos essenciais da teoria crítica da sociedade fundada na distinção entre mundo da vida e sistema e a "tradução" sociológica e institucional do uso público da razão, nos conceitos de sociedade civil e esfera pública.
