Elections and Democracy in Brazil: Victor Nunes Leal and the 1945 Transition

This article discusses the necessary conditions for a democratic government to prevail, with the study Coronelismo: the Municipality and Representative Government in Brazil as the point of departure. The article seeks to identify the book's causal explanations for the emergence of democracy, and more precisely for regimes in which governments lose elections. Why were elections not truly competitive over the course of the Empire and the First Republic? Why did they change after the fall of the Estado Novo? Nunes Leal was one of the few Brazilian authors to explicitly tackle this challenge.

The State as Part of the Republic

The State as Part of the Republic The main objective of this article is to analyze an ideal of civic life, the Republic, based on the form of the sovereign state. Historically, the convergence between Republic and sovereign state has been truncated by the former's commitment to the thesis of royal absolutism. However, as the democratic issue (translated in the values of equality and pluralism) was absorbed by sovereignism, such convergence became more plausible. As viewed in this article, the theoretical bridge of that passage is the concept of political representation. The issue is thus to show in what way a certain vision of the political form (that of the state) can fit into a theory of political representation that contemplates the above-mentioned values.

Internacionalização pelo envolvimento de atores externos no conflito colombiano: atuação da OEA na desmobilização de grupos paramilitares na Colômbia

This paper discusses the effects of the internationalization of the Colombian armed conflict, understood as the participation of foreign actors in programs regarding the resolution of the conflict. Through an analysis of the involvement of multilateral and state actors, the authors argue that this process involved the dilemma between unilateralism and multilateralism. The empirical analysis is centered on the intervention of conflict mediation mechanisms from the Organization of American States (OAS), specifically the Mission to Support the Peace Process (MAPP/OAS), whose scope is aimed at demobilizing paramilitary groups in Colombia.

Heuristic algorithms for the Capacitated Location-Routing Problem and the Multi-Depot Vehicle Routing Problem

The Capacitated Location-Routing Problem (CLRP) is a NP-hard problem since it generalizes two well known NP-hard problems: the Capacitated Facility Location Problem (CFLP) and the Capacitated Vehicle Routing Problem (CVRP). The Multi-Depot Vehicle Routing Problem (MDVRP) is known to be a NP-hard since it is a generalization of the well known Vehicle Routing Problem (VRP), arising with one depot. This thesis addresses heuristics algorithms based on the well-know granular search idea introduced by Toth and Vigo (2003) to solve the CLRP and the MDVRP. Extensive computational experiments on benchmark instances for both problems have been performed to determine the effectiveness of the proposed algorithms. This work is organized as follows: Chapter 1 describes a detailed overview and a methodological review of the literature for the the Capacitated Location-Routing Problem (CLRP) and the Multi-Depot Vehicle Routing Problem (MDVRP). Chapter 2 describes a two-phase hybrid heuristic algorithm to solve the CLRP. Chapter 3 shows a computational comparison of heuristic algorithms for the CLRP. Chapter 4 presents a hybrid granular tabu search approach for solving the MDVRP.

Sympatric colour polymorphisms associated with nonrandom gene flow in cichlid fish of Lake Victoria

Colour polymorphisms have fascinated evolutionary ecologists for a long time. Yet, knowledge on the mechanisms that allow their persistence is restricted to a handful of well-studied cases. We studied two species of Lake Victoria cichlid fish, Neochromis omnicaeruleus and Neochromis greenwoodi, exhibiting very similar sex-linked colour polymorphisms. The ecology and behaviour of one of these species is well studied, with colour-based mating and aggression preferences. Here, we ask whether the selection potentially resulting from female and male mating preferences and aggression biases reduces gene flow between the colour morphs and permits differentiation in traits other than colour. Over the past 14 years, the frequencies of colour morphs have somewhat oscillated, but there is no evidence for directional change, suggesting the colour polymorphism is persistent on an ecological timescale. We find limited evidence of ecomorphological differentiation between sympatric ancestral (plain) and derived (blotched) colour morphs. We also find significantly nonrandom genotypic assignment and an excess of linkage disequilibrium in the plain morph, which together with previous information on mating preferences suggests nonrandom mating between colour morphs. This, together with negative frequency-dependent sexual selection, found in previous studies, may facilitate maintenance of these polymorphisms in sympatry

Obras para piano de Honorio Siccardi : música argentina del siglo XX

Honorio Siccardi (1897-1963) es una figura destacada en el mundo musical argentino y latinoamericano por su múltiple actividad como docente y compositor. Se publica el Catálogo General de sus obras en 1993. Primer trabajo que nos da la posibilidad de conocer su producción artística, la cual consta de 270 obras de diversos géneros musicales y trabajos musicológicos. En el 2002-2004, se desarrolla el proyecto de investigación “Música argentina del siglo XX. Obras para piano de Honorio Siccardi.", subsidiado por Secretaría de Ciencia, Técnica y Posgrado de la UNCuyo, obteniendo como resultado un catálogo de obras para piano, documentación fehaciente que las contextualiza y análisis estilístico de obras seleccionadas, lo que nos permite demostrar la hipótesis propuesta: “Honorio Siccardi(1897-1963), compositor argentino del Siglo XX, desarrolla su estilo vanguardista en sus obras para piano". La publicación total de las obras para piano de Siccardi en: “Obras para piano de Honorio Siccardi. Música argentina del siglo XX" y la grabación de las mismas se concreta con la presentación del CD. “Honorio Siccardi. Obra integral para piano" 2007. Lo importante del enfoque y de los resultados esperados de este trabajo es el rescate, preservación, edición, grabación y difusión de las obras para piano.
