Frondizi y Eisenhower : ¿relación amistosa o incierta?

Resumen: El acceso al Centro de Estudios Nacionales (CEN), archivo personal de Arturo Frondizi, provee nueva documentación sobre su presidencia (1958-1962) de gran relevancia, considerando que el Archivo del Ministerio de Relaciones Exteriores argentino permanece cerrado. Hemos estudiado las relaciones con Estados Unidos durante la presidencia de Eisenhower. El artículo examina el cambio en política exterior que Frondizi implementó para fortalecer la posición argentina en el campo internacional. El país participaba de los valores de Occidente, promovía el multilateralismo y cultivaba buenas relaciones con Estados Unidos. El subyacente y principal objetivo de esta política exterior fue lograr el desarrollo nacional. El artículo se centra en la visita de Frondizi a Estados Unidos –la primera de un presidente argentino– y la de Eisenhower a la Argentina en su viaje a América latina.

The impact of the great recession on employment polarization in Spain

This article analyzes changes in the occupational employment share in Spain for the period 1997-2012 and the way particular sociodemographic groups adapt to those changes. There seems to be clear evidence of employment polarization between 1997 and 2012 that accelerates over the recession. Changes in the composition of the labour supply cannot explain the increase in the share of occupations at the low end of the wage distribution. Sector reallocation may have partially contributed to explain the polarization process in Spain during the years of expansion (1997-2007) but it is a minor factor during the recession. The polarization of occupations within sectors observed, especially during the recession, appears to be related to a decline in routine tasks which is compensated by an increase in occupations with non-routine service contents, which are found both in the low and high end of the wage distribution. Instead, jobs with a higher degree of abstract contents do not appear to increase their share in total employment during these 15 years. The paper finds that this process has affected males more strongly than females because of their higher concentration in occupations more focused on routine tasks. Among males, for workers under 30 years old, we find a decrease in the share of occupations with more routine tasks which turns into increases in those with more abstract content and particularly with more non-routine service content. Instead, male workers over 30 years old seem to remain in declining occupations to a greater extent. Females of different ages are not affected by the abovementioned changes.

鸟类宏观分类和区系地理学研究概述

据Dickinson，E．C．，主编，2003年出版的“m Howard and Moore Gomplete Q蛐ofthe Birds of the World'’一书和2000。2008年的有关文献的记载，在1958～2008年的50年期间，全世界所描述发表鸟类的新种，计 有171种。以每10年中所发表的新种数进行统计比较，以1997～2007年期间所发表的新种为最多；按发现新种所属 目级分类阶元的统计比较，以雀形目发现的新种为最多；按地区进行统计比较，以南美洲发现的新种数为最多，非洲中南部地区和太平洋诸岛为次；在中国境内描记的新种有台湾短翅莺西哟脚嬲旋渤删、峨嵋柳莺场皿瞰灿mzden面、海南柳莺崩砌蚴‰肠砌船、峨嵋鹪莺岛匆船硎豳面、淡尾鹅莺崩锄船．．toror、弄岗穗鹛＆叻帕御赠删、 四川旋木雀眺砌婶删等7种，其中由中国鸟类学者描记的有四川旋木雀和弄岗穗鹛两种。这说明鸟类的宏 观分类研究，时至今日仍有研究的必要和发展空间。种下分类，是探讨同一个物种，随着分布区域的扩大，自然地 理环境条件的变化，而产生地区性分布种群的变异，以致新物种形成的途径，是宏观分类学研究一个物种的演化发 展。所以是当今鸟类分类研究的热点之一。据统计，1958—2008年的50年间，新描述发表的亚种数，约为1 129亚 种。繁殖区域分布较为广泛的种类，所描记的亚种较多。如岛鸫Turd．sp，hbcephaha分化有5l亚种之多。中国鸟类的 分类与区系地理学研究，大致可分为起步时期(1949年以前)、新中国建立之后的考察及宏观分类研究的总结整理 时期(1950—2005)和宏观与微观相结合的发展研究时期(1999年以后)等3个时期。郑作新所出版的《中国鸟类 分布名录》和《中国鸟类区系纲要》等专著，是中国鸟类宏观分类和区系地理学研究较为翔实的阶段性总结，为进 一步研究奠定了坚实的基础。

In order to systematically study the secondary metabolites, the solid-state fermented rice culture of three species of Chaetomium and two of Aspergillus were chemically studied. By the means of chromatograhy and spectroscopy, 55 compounds were isolated and identified, among of them 23 were new ones. The biological activities of some compounds were investigated. 1. From the fungus C. cochliodes, three new epipolythiodioxopiperazines, chaetocochins A-C (1-3) were isolated, together with 8 known ones (4-11). Compounds 1, 3 and 4 showed growth inhibitory effects against cancer cell lines Bre-04, Lu-04 and N-04 with GI50 values from 0.05 to 7.0 μg/mL. 2. Three novel isoquinolines Chaetoindicins A-C (12-14) were isolated and identified from the fungus C. indicum. Chaetoindicin A, Chaetoindicins B-C represented two classes of novel carbon skeletons. 3. Three new compounds, Mollicellins I-J (15-16), and 2-hydroxymethyl-6-methylmethyleugenin (19), were isolated from C. brasiliense.

Brevianamides K-N (40-43), Averins A-C (44-46), and Glyanphenines A-B (47-48) represented three classes of alkaloids. 6. New sesterterpenes and their bioactivities reported from 1997 to 2007 were summarized.

Aspectos de las negociaciones agrícolas, reformas y su impacto interno en los agroalimentos en Japón y región Asia

En general, tanto a nivel empresarial y por parte del Ministerio de Relaciones Exteriores de Japón, existe la tendencia de avanzar con los Acuerdos de Asociación Económica2 (AAEs) en particular en la región Asia-Pacífico; pero ciertos sectores agrícolas y del Ministerio de Agricultura, Forestación y Pesca (MAFF) son más resistentes en hacer avances significativos, para evitar cualquier impacto significativo sobre su agricultura doméstica. Por más de cincuenta años las cooperativas agrícolas han usado su influencia política, apoyada por las comunidades rurales, para bloquear cualquier cambio de reforma. La agricultura japonesa ha disminuido mucho en los últimos 20 años. Las tierras abandonadas3 totalizan actualmente las 400 mil hectáreas. El promedio de edad de los agricultores es de 66 años; el número de productores ha caído a la mitad con 2,6 millones. Existe la predicción de que 1 millón de agricultores dejarán el sector en los próximos 10 años, y el deterioro de las comunidades rurales sigue creciendo. Incluso si Japón adhiere a algunos Acuerdos, la industria agrícola seguirá declinando. En la próxima década se pronostica que la población en Asia se incrementará en 400 millones, por lo que el gobierno japonés no quiere perder más tiempo en trazar sus nuevas estrategias sobre la región. Nunca Japón hizo un planeamiento tan profundo sobre los nuevos lineamientos de la agricultura, que se adoptó como primera prioridad estratégica a nivel nacional, basada sobre todo en la importancia y responsabilidad nacional en tener un suministro seguro de alimentos (incluso los importados) para sus ciudadanos y para la región.

Opportunity cost based analysis of corporate eco-efficiency: A methodology and its application to the CO2-efficiency of German companies

In this paper, we propose the return-to-cost-ratio (RCR) as an alternative approach to the analysis of operational eco-efficiency of companies based on the notion of opportunity costs. RCR helps to overcome two fundamental deficits of existing approaches to eco-efficiency. (1) It translates eco-efficiency into managerial terms by applying the well-established notion of opportunity costs to eco-efficiency analysis. (2) RCR allows to identify and quantify the drivers behind changes in corporate eco-efficiency. RCR is applied to the analysis of the CO2-efficiency of German companies in order to illustrate its usefulness for a detailed analysis of changes in corporate eco-efficiency as well as for the development of effective environmental strategies.

Residential consumption of gas and electricity in the U.S.: The role of prices and income

We study the residential demand for electricity and gas, working with nationwide household-level data that cover recent years, namely 1997-2007. Our dataset is a mixed panel/multi-year cross-sections of dwellings/households in the 50 largest metropolitan areas in the United States as of 2008. We estimate static and dynamic models of electricity and gas demand. We find strong household response to energy prices, both in the short and long term. From the static models, we get estimates of the own price elasticity of electricity demand in the -0.860 to -0.667 range, while the own price elasticity of gas demand is -0.693 to -0.566. These results are robust to a variety of checks. Contrary to earlier literature (Metcalf and Hassett, 1999; Reiss and White, 2005), we find no evidence of significantly different elasticities across households with electric and gas heat. The price elasticity of electricity demand declines with income, but the magnitude of this effect is small. These results are in sharp contrast to much of the literature on residential energy consumption in the United States, and with the figures used in current government agency practice. Our results suggest that there might be greater potential for policies which affect energy price than may have been previously appreciated. (C) 2011 Elsevier B.V. All rights reserved.

A comparison between accelerated hypofractionation and stereotactic ablative radiotherapy (SABR) for early-stage non-small cell lung cancer (NSCLC): Results of a propensity score-matched analysis

BACKGROUND AND PURPOSE: Stereotactic ablative radiotherapy (SABR) has become standard for inoperable early-stage non-small cell lung cancer (NSCLC). However, there is no randomized evidence demonstrating benefit over more fractionated radiotherapy. We compared accelerated hypofractionation (AH) and SABR using a propensity score-matched analysis.

MATERIALS AND METHODS: From 1997-2007, 119 patients (T1-3N0M0 NSCLC) were treated with AH (48-60Gy, 12-15 fractions). Prior to SABR, this represented our institutional standard. From 2008-2012, 192 patients (T1-3N0M0 NSCLC) were treated with SABR (48-52Gy, 4-5 fractions). A total of 114 patients (57 per cohort) were matched (1:1 ratio, caliper: 0.10) using propensity scores.

RESULTS: Median follow-up (range) for the AH cohort was 36.3 (2.5-109.1) months, while that for the SABR group was 32.5 (0.3-62.6)months. Three-year overall survival (OS) and local control (LC) rates were 49.5% vs. 72.4% [p=0.024; hazard ratio (HR): 2.33 (1.28, 4.23), p=0.006] and 71.9% vs. 89.3% [p=0.077; HR: 5.56 (1.53, 20.2), p=0.009], respectively. On multivariable analysis, tumour diameter and PET staging were predictive for OS, while the only predictive factor for LC was treatment cohort.

CONCLUSIONS: OS and LC were improved with SABR, although OS is more closely related to non-treatment factors. This represents one of the few studies comparing AH to SABR for early-stage lung cancer.

Arqueologia das aprendizagens de âmbito profissional no concelho de Alandroal

Esta dissertação enquadra-se no âmbito do projeto de investigação “Arqueologia das Aprendizagens no Concelho de Alandroal”1, promovido pelo Centro de Investigação em Educação e Psicologia da Universidade de Évora. Este projeto visa apurar quais as aprendizagens disponíveis neste concelho entre 1997 e 2007, bem como determinar o que foi aprendido pela população em contextos formais e não-formais. É também objetivo deste projeto descobrir o que mudou na vidas das pessoas e da comunidade, ou seja verificar qual o impacto das aprendizagens e dos investimentos realizados num território que apresenta uma das mais elevadas taxas de analfabetismo e uma baixa taxa de qualificação. A presente dissertação partilha destes objetivos mas centra-se na dimensão das aprendizagens de âmbito profissional. O principal contributo deste trabalho de investigação é a apresentação do estudo relativo às aprendizagens de âmbito profissional concretizadas pela população do Alandroal, no período 1997-2007 e respetivas consequências a nível das trajetórias pessoais e profissionais. Este estudo é completado pela apresentação de importantes conclusões, retiradas da análise dos dados que foram recolhidos durante a realização do projeto “Arqueologia das Aprendizagens no Concelho de Alandroal”; ABSTRACT:This thesis is included in the research project, with the title: “Learning Arqueology in Alandroal”2, promoted by the Centre for Research in Education and Psychology of the University of Évora, in Portugal. That project targets the identification of which learning processes were available in Alandroal, during the period between 1997 and 2007, and to determine what has been learned by the population in formal and non-formal contexts. Also, that study aims to discover, what were the changes, in persons ‘lives and within the community. In summary, the project aims to verify the impact of the learning processes, as well as the impact of the investments made, on a territory that presents one of the highest levels of illiteracy, followed by a low qualification level. Now, the research work here presented, shares those same objectives, but it’s focused on the professional education. The main contribute of this research study, is to present the consequences of those professional’s learning, developed by the population of Alandroal, for the personal and professional choices and trajectories of that same population, between the years of 1997 and 2007. This study is also completed with the presentation of important conclusions, inferred from the analysis of data collected throughout the realization of the “Learning Arqueology in Alandroal” project.
