Abstract

The first observations of UV global radiation in Chile with a portable multichannel radiometer are reported. Four UV wavelengths are included: 305, 320, 340 and 380 nm. Observation latitudes spanning from 18 degrees to 53 degrees S allow an estimation of latitudinal variations in daily maxima for both summer and winter. Measurements over Santiago deviate from a smooth latitudinal profile, probably as a consequence of urban air pollution. The main effect of this is to prevent UV solar radiation from reaching the ground, especially during winter. Altitudinal increments in UV radiation are estimated by comparing observations along the coast and valleys with others on the Andes and one isolated summit. Diurnal variations in the height increment support an increase from morning to evening. The results indicate that in rural areas the altitudinal increment is lower (4%-10% per kilometre) than that reported for Europe, reaching very low magnitudes (2% or less) in the Andean summits of desert regions.

Resource exploitation and cross-region growth trajectories: nonparametric estimates for Chile.

As a sector of primary concern for national development strategies, mining keeps stimulating an intensive debate in Chile, regarding its role for long-term growth. Partly drawn on theoretical contributions to growth and mineral resource accounting, this analysis assesses patterns of economic growth across Chilean regions. The theoretical and methodological rationale for focusing on weak sustainability, by testing convergence across regions in a distribution dynamics perspective, is first discussed. This is followed by a brief review of policy issues and previous empirical findings of concern to Chile's mining and regional growth. Panel data over the period 1960-2001 are analysed, with growth measured in terms of both income per capita as such, and sustainable measures of this variable. Kernel density and quantile regression estimates indicate persistent bimodal (if not possibly trimodal) distribution of nationally standardised regional incomes per capita, whereby conditions for cross-region convergence are matched only within the inner range of this distribution.

[What determines the time-lag for publications in Revista Médica de Chile?].

The number of manuscripts submitted for publication in Revista Médica de Chile has increased steadily. Consequently, the number of external experts that generously contribute in the peer review process has also been enlarged. When the manuscripts return to the authors with specific requests to be improved, according to the criticisms raised by their reviewers or the editors, more time is added until a corrected version is received and accepted. After acceptance, the manuscripts are programmed by the editors to be included in future monthly issues of the Revista. The number of manuscripts that can be included in an issue is limited by the number of pages accorded between the publishers and the owner institution. Therefore, an additional time-lag occurs: research articles and case reports may be published 6-8 months after they were finally accepted, while reviews and special articles have to wait even more. As experienced in prestigious journals worldwide, a computational program to handle the editorial process through the Internet is needed, but it is not yet available in Spanish language. Although it should fasten communications and facilitate the authors a rapid insight in the stages of the editorial process where their manuscripts are, the increasing number of submissions, the current acceptance rate and the limitation in space will still retard the publications once they are accepted.
