Beneficios y desventajas para la industria textil colombiana, específicamente en el sub sector de algodón, ante la eventual firma y ratificación de un tratado de libre comercio entre Colombia e India

Este proyecto realiza un estudio sobre las principales características de los sub sectores de producción de algodón en India y en Colombia. Ello, debido a que a pesar de no existir ningún acuerdo comercial en la materia entre ambos países, la hipótesis de que este llegase a presentarse resulta atractiva. En este sentido, las características del cultivo, producción y comercialización tanto de India como de Colombia, ofrecen un panorama que invita a reflexionar sobre los beneficios y desventajas para el sub sector de algodón, frente a la eventual firma de un Tratado de Libre Comercio. En este orden de ideas, en este trabajo se observan elementos tales como los distintos pormenores de cada proceso de producción, además de las estrategias de comercialización y las políticas gubernamentales de cada país con relación al cultivo de algodón. Asimismo, se da una mirada a la actualidad del sub sector de algodón en Colombia e India a través la balanza comercial de estos países. De este modo, se proponen una serie de estrategias para contrarrestar las desventajas que podrían presentarse, como a su vez plantear los beneficios que también tendrían lugar y las políticas a implementar.

This paper reviews a study to analyze the number of times alphabet symbols occur in three commonly used basal reader series.

The roadmap to banking union: a call for consistency. CEPS Commentary, 30 August 2012

The proposal to move to a full banking union in the eurozone means a radical regime shift for the EU, since the European Central Bank will supervise the eurozone banks and effectively end ‘home country rule’. But how this is implemented raises a number of questions and needs close monitoring, explains CEPS CEO Karel Lannoo in this new Commentary.

Assessment of the consistency of near-infrared water vapor line intensities using high-spectral-resolution ground-based Fourier transform measurements of solar radiation

Calculations of the absorption of solar radiation by atmospheric gases, and water vapor in particular, are dependent on the quality of databases of spectral line parameters. There has been increasing scrutiny of databases such as HITRAN in recent years, but this has mostly been performed on a band-by-band basis. We report nine high-spectral-resolution (0.03 cm(-1)) measurements of the solar radiation reaching the surface in southern England over the wave number range 2000 to 12,500 cm(-1) (0.8 to 5 mm) that allow a unique assessment of the consistency of the spectral line databases over this entire spectral region. The data are assessed in terms of the modeled water vapor column that is required to bring calculations and observations into agreement; for an entirely consistent database, this water vapor column should be constant with frequency. For the HITRAN01 database, the spread in water vapor column is about 11%, with distinct shifts between different spectral regions. The HITRAN04 database is in significantly better agreement (about 5% spread) in the completely updated 3000 to 8000 cm(-1) spectral region, but inconsistencies between individual spectral regions remain: for example, in the 8000 to 9500 cm(-1) spectral region, the results indicate an 18% (+/- 1%) underestimate in line intensities with respect to the 3000 to 8000 cm(-1) region. These measurements also indicate the impact of isotopic fractionation of water vapor in the 2500 to 2900 cm(-1) range, where HDO lines dominate over the lines of the most abundant isotope of H2O.

Minimising the latency induced by consistency control, within a large scale multi-user distributed virtual reality system

Where users are interacting in a distributed virtual environment, the actions of each user must be observed by peers with sufficient consistency and within a limited delay so as not to be detrimental to the interaction. The consistency control issue may be split into three parts: update control; consistent enactment and evolution of events; and causal consistency. The delay in the presentation of events, termed latency, is primarily dependent on the network propagation delay and the consistency control algorithms. The latency induced by the consistency control algorithm, in particular causal ordering, is proportional to the number of participants. This paper describes how the effect of network delays may be reduced and introduces a scalable solution that provides sufficient consistency control while minimising its effect on latency. The principles described have been developed at Reading over the past five years. Similar principles are now emerging in the simulation community through the HLA standard. This paper attempts to validate the suggested principles within the schema of distributed simulation and virtual environments and to compare and contrast with those described by the HLA definition documents.

The consistency of private and public real estate within mixed-asset portfolios

This study considers the consistency of the role of both the private and public real estate markets within a mixed-asset context. While a vast literature has developed that has examined the potential role of both the private and public real estate markets, most studies have largely relied on both single time horizons and single sample periods. This paper builds upon the analysis of Lee and Stevenson (2005) who examined the consistency of REITs in a US capital market portfolio. The current paper extends that by also analyzing the role of the private market. To address the question, the allocation of both the private and traded markets is evaluated over different holding periods varying from 5- to 20-years. In general the results show that optimum mixed-asset portfolios already containing private real estate have little place for public real estate securities, especially in low risk portfolios and for longer investment horizons. Additionally, mixed-asset portfolios with public real estate either see the allocations to REITs diminished or eliminated if private real estate is also considered. The results demonstrate that there is a still a strong case for private real estate in the mixed-asset portfolio on the basis of an increase in risk-adjusted performance, even if the investor is already holding REITs, but that the reverse is not always the case.
