Efectos fiscales de los asentamientos hidroeléctricos: el caso de la cuenca de los Ríos Negro y Nare en Colombia

Con la presencia de asentamientos hidroeléctricos en su territorio, los municipios del oriente y nordeste antioqueño han visto afectada su estructura tributaria y territorial, a pesar de la reglamentación compen­satoria del sector eléctrico. Este artículo, analiza los efectos tributarios generados por la compensación del impuesto predial. Para lograrlo se revisan los montos recibidos por los municipios de las empresas generadoras y se realiza una indagación empírica del impuesto bajo los escenarios con y sin asenta­mientos hidroeléctricos. De esta forma se determina el diferencial tributario. Se concluye que, además de la insuficiencia de las transferencias para compensar la pérdida del capital natural de las cuencas hidroeléctricas, la expansión del sector eléctrico genera regresividad tributaria, por causa de privilegios y exenciones concebidos por las Leyes.

Exporting the racial republic: African colonization, national citizenship, and the transformation of U.S. expansion, 1776-1864

The effort to create a colony of African Americans on the west coast of Africa was one of the most celebrated and influential movements in the United States during the first half of the 19th century. While historians have often viewed African colonization through the lens of domestic anti-slavery politics, colonization grew from an imperial impulse which promised to transform the identities of black colonists and indigenous Africans by helping them to build a democratic nation from the foundation of a settler colony. By proposing that persons of African descent could eventually become self-governing subjects, the liberal framework behind colonization offered the possibility of black citizenship rights, but only within racially homogenous nation-states, which some proponents of colonization imagined might lead to a “United States of Africa.” This dissertation examines how the notion of expanding democratic ideals through the export of racial nationhood was crucial to the appeal of colonization. It reveals how colonization surfaced in several crucial debates about race, citizenship, and empire in the antebellum United States by examining discussions about African Americans’ revolutionary claims to political rights, the bounds of US territorial expansion, the removal of native populations in North America, and the racialization of national citizenship, both at home and abroad. By examining African colonization from these perspectives, this dissertation argues that the United States’ efforts to construct a liberal democracy defined by white racial identity were directly connected to the nation’s emerging identity as a defender and exporter of political liberty throughout the world.

Proposta de uma matriz de decisão em energia hidrelétrica com o uso do método multicritério, para formulação de políticas públicas no estado do Paraná

Brazil is internationally acknowledged for its renewable sources, most notably, hydroelectric power plant projects which correspond to 65% of electricity production supply to the National Interconnected System. The main question behind this research is: what are the weights and the relative importance of the variables which have influence on the decision making process for the expansion of hydroelectric generation projects in Parana? The main objective is to propose a multi-criteria decision procedure, in association with water sources options that take into consideration the weight and relative importance of the alternatives having influence on the decision by enterprises in the generation of electricity in the state of Paraná. As far as the approach to the problem is concerned, this research can be classified as having mixed methodologies, applying Content Analysis, Delphi technique and the Analytic Hierarchy Process. Following Delphi methodology, a group of 21 was selected for data collection, all of those linked to Paranaense hydroelectricity market. And the main result was the construction of a decision tree in which it was possible to identify the importance and relative weight of the elements associated with the four dimensions of energy. In environmental dimension, the highest relative weight was placed on the loading capacity of Parana system; the economic dimension, the amortization of investment; in social dimension, the generation of direct work places and in institutional dimension, the availability of suitable sources of financing. Policy makers and business managers make their decisions based on specific criteria related to the organization segment, market information, economic and political behavior among other indicators that guide them in dealing with the typical tradeoffs of projects in hydropower area. The results obtained in the decision tree show that the economic bias is still the main factor in making investment decisions. However, environmental impacts on the State loading capacity, income generation, providing opportunities for direct as well as indirect jobs. And at an institutional level, the absence of funding sources show that the perception of experts is focused on other issues beyond the logic behind development per se. The order of priority of variables in this study indicates that in the current environment of uncertainty in the Brazilian economy as many variables must be analyzed and compared in order to optimize the scarce resources available to expand local development in relation to Paranaense water matrix.
