Regalías y desequilibrios territoriales en Colombia: una brecha que no se cierra

Este artículo analiza el impacto de las regalías como una de las contraprestaciones de mayor relevancia que perciben los territorios colombianos para el desarrollo territorial, dadas las múltiples controversias que se han suscitado durante los últimos 25 años sobre la pertinencia y modalidades de aplicación de estos recursos por parte de las entidades territoriales, en tanto que motores de compensación de la disparidad regional.

ACE research vignette 012 : woman entrepreneurs

This series of research vignettes is aimed at sharing current and interesting research findings from our team and other international Entrepreneurship researchers. In this vignette, Associate Professor, Dr Michael Stuetzer and Professor Per Davidsson investigate where Australia ranks on the world stage in terms of female entrepreneurship, and discover that Australia is in a very healthy position.

A Tradable Permit System in an Intertemporal Economy

It is known that in an intertemporal competitive economy, a tradable permit system may not achieve efficiency without setting appropriate permit interest rates (i.e., rewards for holding permits). To find the rates, however, we need to know in advance the path of efficient permit prices, which is difficult to obtain. This study intends to solve this problem in two ways. First, we analyze a special case in which the permit interest rates are given by a simple rule. For example, if the marginal abatement cost of pollution emission is constant, then the appropriate rate is to equal the monetary interest rate. As is the case for global warming, if the damage is caused in the future far beyond the planning period of the environmental program, the appropriate rate coincides with the marginal self-recovery of environmental stock under certain conditions. As a second approach, we propose a tradable permit system with a permit bank, as a mechanism by which the permit interest rates are generated endogenously without governmental intervention other than the issuance of permits. However, we also show that this approach raises the problem of indeterminacy of the equilibrium. © 2013 Springer Science+Business Media Dordrecht.

Diário da Constituinte [gravação de vídeo] : [programa n. 012]

Marco Maciel (PFL-PE), Ministro Chefe da Casa Civil, comparece à Subcomissão do Poder Executivo da Assembleia Nacional Constituinte (ANC) e defende a permanência do presidencialismo com a mesma divisão de poderes, mas com o fortalecimento do Legislativo e do Judiciário. O Senador José Fogaça (PMDB-RS), relator da Subcomissão, expõe que, após consulta aos parlamentares e outros setores da sociedade, não acredita na permanência do presidencialismo. Marco Marciel defende a permanência do mandato do Presidente Sarney (PMDB-MA) em seis anos. O Deputado Vivaldo Barbosa (PDT-RJ), 1º vice-presidente da Subcomissão do Poder Executivo, se posiciona contra o mandato de seis anos do Presidente José Sarney.

Diário da Constituinte [gravação de vídeo] : [programa n. 336]

O Congresso pode ser reunir para votar o pacote fiscal. A ideia de convocação extraordinária para votar a reforma tributária do governo é do Constituinte Carlos Chiarelli. Constituintes buscam acordos e negociações para mudança no regimento interno da Constituinte.

Liquid-liquid extraction of Pa-233(V) with Aliquat 336

The extraction of protactinium with Aliquat 336 (methyl-tri-caprylyl ammonium chloride) in toluene, cyclohexane and chloroform from HCl, HNO3, H2SO4, HClO4, HF and mixed HCl-HF media was investigated by radioactive tracer technique. Distribution ratios of protactinium between the aqueous solution and the organic phase were determined as a function of shaking time, concentrations of acid in aqueous solution phase, extractant concentration and type of diluents in the organic phase. Aliquat 336 can almost quantitatively extract protactinium from strong HCl solution. At the same time, small amounts of HF in HCl solutions have a strong effect on Pa distribution.

Heat capacity and thermochemical study of trifluoroacetamide (C2H2F3NO)

The low-temperature heat capacities of trifluoroacetamide were precisely determined with a small sample precision automated adiabatic calorimeter over the temperature range from 78 to 404 K. A solid-to-solid phase transition, a fusion and a phase transition from a liquid crystalline phase to fully liquid phase have been observed at the temperatures of 336.911+/-0.102, 347.622+/-0.094 and 388.896+/-0.160 K, respectively. The molar enthalpies of these phase transitions as well as the chemical purity of the substance were determined to be 5.576+/-0.004, 11.496+/-0.007, 1.340+/-0.005 kJ mol(-1) and 99.30 mol%, respectively, on the basis of the heat capacity measurements. The molar entropies of the three phase transitions were calculated to be 16.550+/-0.012, 33.071+/-0.029 and 3.447+/-0.027 J mol(-1) K-1, respectively. Further researches of the thermochemical properties for this compound have been carried out by means of TG and DSC techniques. (C) 2000 Elsevier Science B.V. All rights reserved.
