The Economic Effects of Improving Investor Rights in Portugal

The Portuguese economy has performed remarkably well since joining the EU in 1986. Output per worker grew at an annual rate of 2.25%. The relative price of investment has declined. Real investment has increased compared to output, in part fuelled by an increase in capital inflows. At the same time, resource allocation seems to have improved as well: firm-level data shows a significant decline in the dispersion of labor productivity and size across firms. This paper argues that improvements in outside investor rights that have taken place since Portugal joined the EU is a prime candidate to explain this set of facts.

Studies on arbuscular mycorrhiza (AM) in the Alentejo (Portugal) using pea mutants resistant to AM fungi as a control tool for field conditions

The utilization and management of arbuscular mycorrhiza (AM) symbiosis may improve production and sustainability of the cropping system. For this purpose, native AM fungi (AMF) were sought and tested for their efficiency to increase plant growth by enhanced P uptake and by alleviation of drought stress. Pot experiments with safflower (Carthamus tinctorius) and pea (Pisum sativum) in five soils (mostly sandy loamy Luvisols) and field experiments with peas were carried out during three years at four different sites. Host plants were grown in heated soils inoculated with AMF or the respective heat sterilized inoculum. In the case of peas, mutants resistant to AMF colonization were used as non-mycorrhizal controls. The mycorrhizal impact on yields and its components, transpiration, and P and N uptake was studied in several experiments, partly under varying P and N levels and water supply. Screening of native AMF by most probable number bioassays was not very meaningful. Soil monoliths were placed in the open to simulate field conditions. Inoculation with a native AMF mix improved grain yield, shoot and leaf growth variables as compared to control. Exposed to drought, higher soil water depletion of mycorrhizal plants resulted in a haying-off effect. The growth response to this inoculum could not be significantly reproduced in a subsequent open air pot experiment at two levels of irrigation and P fertilization, however, safflower grew better at higher P and water supply by multiples. The water use efficiency concerning biomass was improved by the AMF inoculum in the two experiments. Transpiration rates were not significantly affected by AM but as a tendency were higher in non-mycorrhizal safflower. A fundamental methodological problem in mycorrhiza field research is providing an appropriate (negative) control for the experimental factor arbuscular mycorrhiza. Soil sterilization or fungicide treatment have undesirable side effects in field and greenhouse settings. Furthermore, artificial rooting, temperature and light conditions in pot experiments may interfere with the interpretation of mycorrhiza effects. Therefore, the myc- pea mutant P2 was tested as a non-mycorrhizal control in a bioassay to evaluate AMF under field conditions in comparison to the symbiotic isogenetic wild type of var. FRISSON as a new integrative approach. However, mutant P2 is also of nod- phenotype and therefore unable to fix N2. A 3-factorial experiment was carried out in a climate chamber at high NPK fertilization to examine the two isolines under non-symbiotic and symbiotic conditions. P2 achieved the same (or higher) biomass as wild type both under good and poor water supply. However, inoculation with the AMF Glomus manihot did not improve plant growth. Differences of grain and straw yields in field trials were large (up to 80 per cent) between those isogenetic pea lines mainly due to higher P uptake under P and water limited conditions. The lacking N2 fixation in mutants was compensated for by high mineral N supply as indicated by the high N status of the pea mutant plants. This finding was corroborated by the results of a major field experiment at three sites with two levels of N fertilization. The higher N rate did not affect grain or straw yields of the non-fixing mutants. Very efficient AMF were detected in a Ferric Luvisol on pasture land as revealed by yield levels of the evaluation crop and by functional vital staining of highly colonized roots. Generally, levels of grain yield were low, at between 40 and 980 kg ha-1. An additional pot trial was carried out to elucidate the strong mycorrhizal effect in the Ferric Luvisol. A triplication of the plant equivalent field P fertilization was necessary to compensate for the mycorrhizal benefit which was with five times higher grain yield very similar to that found in the field experiment. However, the yield differences between the two isolines were not always plausible as the evaluation variable because they were also found in (small) field test trials with apparently sufficient P and N supply and in a soil of almost no AMF potential. This similarly occurred for pea lines of var. SPARKLE and its non-fixing mycorrhizal (E135) and non-symbiotic (R25) isomutants, which were tested in order to exclude experimentally undesirable benefits by N2 fixation. In contrast to var. FRISSON, SPARKLE was not a suitable variety for Mediterranean field conditions. This raises suspicion putative genetic defects other than symbiotic ones may be effective under field conditions, which would conflict with the concept of an appropriate control. It was concluded that AMF resistant plants may help to overcome fundamental problems of present research on arbuscular mycorrhiza, but may create new ones.

Algunas reflexiones para una caracterización de los bomberos profesionales del distrito de Coimbra (Portugal): identidad, riesgos y prácticas operacionales

En la nueva era del riesgo emergente el desafío que afrontan las sociedades es saber contornear las incertidumbres. ¿Cómo actúan los estados nacionales considerados semi-periféricos,1 como el portugués, frente a este nuevo orden? Cuando restringimos los riesgos solo a los naturales y tecnológicos, necesariamente, en Portugal, debemos hablar de responsabilidad pública. En lo que concierne a su Estado, es su misión, a través de las figuras jurídicamente creadas para el efecto (las instituciones en el ámbito de la protección civil) asegurar la protección y socorro de las personas y bienes. Verificamos en los últimos años una sucesión de documentos legales que reglamentan el sistema de protección civil, lo que nos coloca sobre el cuadro investigativo de intentar conocer cómo es que en una sociedad semiperiférica, uno de sus “sujetos” garantes de la protección y socorro, los bomberos profesionales del distrito de Coimbra (Portugal), se posiciona operacionalmente en presencia de las disposiciones legales, teniendo en cuenta los contornos híbridos de la sociedad del riesgo. ¿Quiénes son?, ¿cuáles sus prácticas operacionales?, ¿cómo se integran con las poblaciones? Estas son algunas de las cuestiones a responder en la investigación en curso para una disertación de maestría en la Universidad de Coimbra.

Perfil logístico de Portugal

El presente documento ofrece un estudio del perfil logístico de Portugal, abarcando diferentes aspectos que afectan la competitividad y el desempeño de la cadena logística de un país, con la finalidad de conocer a uno de los socios comerciales con los cuáles Colombia se encuentra negociando, en este caso Portugal, uno de los 28 países que hace parte del reciente tratado de libre comercio aprobado con la Unión Europea, es preciso estudiar las ventajas competitivas que poseen dichos socios, a las cuales el país se enfrenta en un mundo globalizado. Para el desarrollo de este trabajo se determinaron a partir de un análisis competitivo del país; las principales ciudades y puertos; logrando establecer un completo panorama de la situación logística en Portugal.
