Los indios de Riobamba y la revolución de Quito, 1757-1814 (Debates)

Este estudio analiza las diversas posiciones asumidas por los indígenas frente a la Revolución de Quito de 1809. Siguiendo a dos personajes clave del Corregimiento de Riobamba, un cacique y un indio, busca las causas de la adhesión o del rechazo. Con ese propósito se estudian varias coyunturas que empiezan a mediados del siglo XVIII, desde las peticiones caciquiles y el posterior reacomodo de las autoridades indígenas efectuadas por los reformistas borbónicos, las continuas imposiciones tributarias y el terremoto de 1797, que desembocan en el levantamiento indígena de 1803. El artículo muestra una ruptura radical entre los indios del común y el pensamiento criollo fundador de la nación.

El legado de Cádiz: ciudadanía y cultura política en la Gobernación de Cuenca, 1812-1814 (Estudios)

Este trabajo analiza el legado de las Cortes de Cádiz y de la Constitución de 1812 en Cuenca entre 1812 y 1814. Estudia los principales cambios políticos relacionados con los derechos de diversos actores sociales, así como el rompimiento de antiguas formas de relación social. Los cambios políticos se relacionaron con la introducción de nuevos conceptos y prácticas como ciudadanía, soberanía, elección y representación, tanto en el mundo criollomestizo como en el indígena (población cañari) de la provincia. Se analiza la abolición del tributo indígena, el servicio personal y la mita, además se estudian algunos cambios administrativopolíticos como la creación de los ayuntamientos constitucionales, las diputaciones provinciales y nacionales.

Las Guyanas holandesas en América Latina (1600-1814) [Estudios]

This article starts by considering the fact that the Guyanas can be understood as an atypical region in the Latin-American context. The lapse of analysis of this study is from 1600 to 1814, period of development of Dutch Guyanas, which was the base of the Surinam Republic and the Co-operative Republic of Guyana. These are highlighted for being the unique Latin-American entities that were not colonized by the Catholics Monarchies, for the absence of missionary activities until 1735, and also for the absence of private action. These colonies offer an interesting study field about comparative development with other South American regions.

Rotational spectra induced by vibrations

Mizushima and Venkateswarlu showed in 1953 that certain molecules have the property that excited vibrational states may possess rotational spectra even when the rotational spectrum of the ground vibrational state is forbidden by symmetry. We call such a spectrum a vibrationally induced rotational spectrum, and have made a systematic examination of the point groups which permit such behaviour. We also give formulae for the approximate line frequencies and intensities in these spectra, and discuss some of the problems involved in observing them. The spectra can only arise from degenerate vibrational states, and are of three possible types: i) symmetric top perpendicular spectra, shown by molecules belonging to the point groups Dnh, Dn and Cnh, where n is odd; (ii) symmetric top parallel spectra, shown by molecules belonging to Dnd and S2n, where n is even; and (iii) spherical top spectra, shown by molecules belonging to T or Td. Excited vibrational states of polar molecules of point groups Cnv or Cn, where n is odd, may also possess vibrationally induced perpendicular components of type (i), in addition to their ordinary parallel spectra. In addition to the above limitations on the point groups there are, in general, limitations on the symmetry species of the degenerate vibrational states.

An application of the DEA double bootstrap to examine sources of efficiency in Bangladesh rice farming

In this article we examine sources of technical efficiency for rice farming in Bangladesh. The motivation for the analysis is the need to close the rice yield gap to enable food security. We employ the DEA double bootstrap of Simar and Wilson (2007) to estimate and explain technical efficiency. This technique overcomes severe limitations inherent in using the two-stage DEA approach commonly employed in the efficiency literature. From a policy perspective our results show that potential efficiency gains to reduce the yield gap are greater than previously found. Statistically positive influences on technical efficiency are education, extension and credit, with age being a negative influence.
