Expectativas y producción industrial en el Uruguay: interdependencia sectorial y tendencias comunes

Se explora la interdependencia entre las expectativas y el crecimiento en un análisis aplicado a la industria manufacturera uruguaya, que se considera desagregada en cuatro grupos industriales diferenciados por su inserción comercial y especialización productiva. La investigación muestra que entre las expectativas de los empresarios y el crecimiento de la producción existe una relación de equilibrio a nivel de cada grupo industrial. En los grupos de perfil más transable esta relación es de predeterminación, denotando la utilidad de las expectativas para anticipar el crecimiento sectorial. Se prueba que las expectativas de los cuatro grupos industriales presentan una tendencia común en el largo plazo, que se identifica con aquella que guía a la del grupo exportador. Las simulaciones de impulso-respuesta derivadas del modelo de autorregresión vectorial var multisectorial reafirman la importancia de las industrias más expuestas a la competencia internacional en la propagación de los shocks de más corto plazo.

Inversión extranjera directa y desigualdad de los ingresos en América Latina. Un análisis sectorial

En este trabajo se analiza la relación entre la inversión extranjera directa (ied) y la desigualdad de los ingresos en América Latina. En particular, se estima el efecto de la ied desde una perspectiva sectorial y se identifican tres grandes sectores: primario, industria manufacturera y servicios. Mediante un panel de datos para 13 economías en el período 1980-2009, se encontró evidencia empírica de un efecto positivo de la ied en la desigualdad de los ingresos provocada por aquellas inversiones localizadas en los sectores de servicios e industria manufacturera.

Cortical representation of the horizon in V1 and peripheral scaling in mammals with lateral eyes

In the present investigation we mapped the primary visual area of the South American diurnal rodent, Dasyprocta aguti, by standardized electrophysiological mapping techniques. In particular, we performed a series of mapping experiments of the visual streak in the primary visual cortex. We found that the representation of the visual streak in V1 is greatly expanded, the nasal 10 degrees of the visual streak representation occupies ten times more cortical area than equivalent areas in the central or temporal representation. Comparison of these data with those on the density of ganglion cells in the retina at corresponding locations in the visual field reveal a significant mismatch between these two variables. The nasal representation is greatly expanded along the horizontal meridian in V1 as compared to the central and temporal regions whereas the density of ganglion cells decreases with progression along the visual streak from central region towards the nasal or temporal visual field. A review of the available data reveals that all lateral-eyed mammals exhibit a similar mismatch between the retinal and cortical representation of the visual field, and this mismatches is greater in those species with well defined visual streaks such as rabbit and agouti.

Multilatinas na global economy. historical characterization, sectorial and space

The successive crises for which has passed in the world economy since the years 1970, together with the United States 'hegemonic crisis, have created the conditions for the reordering and the construction of a multipolar world, with the increasing importance of some peripheral countries into the world economy, particularly with regard to capital flows. This article represents an effort to bring to light the analysis on the decrease of importance of developed countries in world investment flows and corresponding increase in the relevance of some peripheral countries. The objective underlying the text is understanding the expansion of space circuits of production of multinational companies in Latin America (Multilatinas) at different spatial scales, by means of an analysis of the temporal, spatial and sectoral dimensions of the investments. The methodological procedures adopted covered survey, selection and bibliographic data compilation, reading in international organizations (UNCTAD and ECLAC), systematization of data, analysis of data in the light of the theoretical reflections.

Challenges of Knowledge Representation in Contemporary Archival Science

Since its emergence as a discipline, in the nineteenth century (1889), the theory and practice of Archival Science have focused on the arrangement and description of archival materials as complementary and inseparable nuclear processes that aim to classify, to order, to describe and to give access to records. These processes have their specific goals sharing one in common: the representation of archival knowledge. In the late 1980 a paradigm shift was announced in Archival Science, especially after the appearance of the new forms of document production and information technologies. The discipline was then invited to rethink its theoretical and methodological bases founded in the nineteenth century so it could handle the contemporary archival knowledge production, organization and representation. In this sense, the present paper aims to discuss, under a theoretical perspective, the archival representation, more specifically the archival description facing these changes and proposals, in order to illustrate the challenges faced by Contemporary Archival Science in a new context of production, organization and representation of archival knowledge.

On the equivalence between the wave-packet phase space representation (WPPSR) and the phase space generated by the squeezed states

We show that the parametrized Wave-Packet Phase Space representation, which has been studied earlier by one of the authors, is equivalent to a Squeezed States Phase Space Representation of quantum mechanics. © 1988.

A squeezed state holomorphic phase space representation of equations of motion

A mapping scheme is presented which takes quantum operators associated to bosonic degrees of freedom into complex phase space integral kernel representatives. The procedure consists of using the Schrödinger squeezed state as the starting point for the construction of the integral mapping kernel which, due to its inherent structure, is suited for the description of second quantized operators. Products and commutators of operators have their representatives explicitly written which reveal new details when compared to the usual q-p phase space description. The classical limit of the equations of motion for the canonical pair q-p is discussed in connection with the effect of squeezing the quantum phase space cellular structure. © 1993.

Representation of transmission lines: comparison of models and parameters distributed discrete parameters

A transmission line is characterized by the fact that its parameters are distributed along its length. This fact makes the voltages and currents along the line to behave like waves and these are described by differential equations. In general, the differential equations mentioned are difficult to solve in the time domain, due to the convolution integral, but in the frequency domain these equations become simpler and their solutions are known. The transmission line can be represented by a cascade of π circuits. This model has the advantage of being developed directly in the time domain, but there is a need to apply numerical integration methods. In this work a comparison of the model that considers the fact that the parameters are distributed (Universal Line Model) and the fact that the parameters considered concentrated along the line (π circuit model) using the trapezoidal integration method, and Simpson's rule Runge-Kutta in a single-phase transmission line length of 100 km subjected to an operation power. © 2003-2012 IEEE.
