The truth about freedom of choi

El presente es un análisis de los principales rasgos y tendencias que caracterizan hoy a la triada Sociedad-Estado-Mercado. Hace énfasis en la hegemonía del mercado y ofrece un recuento analítico de los hechos que la acompañan como son: la transnacionalización de la cadena de valor, el ascenso de la sociedad del conocimiento, el protagonismo oligopólico de la empresa transnacional, la nueva división social transnacional del trabajo, el proceso de reconfiguración cultural, la exclusión social y la subordinación del Estado, entre otros. El planteamiento que subyace a estas consideraciones es lo que acá se denomina “la verdad sobre la libertad de elegir”, con lo cual se quiere hacer referencia al hecho de que las relaciones Sociedad-Estado se encuentran hoy mediatizadas por el mercado, arrojando, como consecuencia, una involución heterónoma de la Sociedad y del mismo Estado liberal.The actual is an academic analysis of the main features on the day has the triad Society, State and Market. It emphasizes the market hegemony and offers an analytical recount of the facts that go with, as the value chain internationalization, the knowledge society rise, the translational enterprise powerful mark up, the new international social labour division, the cultural reshape process, the social exclusion, the State subordination, among others. The underlying outlining these issues is what the author calls “The truth under the free to choose”, as a reference to the fact that the relationships between the Society and the State are hindered by the Market with a heteronomous society involution as consequence

Energy prices in Europe. Evidence of persistence across markets

This paper deals with the behavior of energy price changes and how their shocks exert an impact on suppliers and consumers in different markets. For this purpose, a fractional integration model is used to evaluate the persistence and mean reversion in prices across the major European markets (Germany, France, Italy, UK, Spain). We compare the results with other major players as the US and Japan, to understand, first, if the European behavior is different, and second, if geopolitical shocks that are affecting this market are expected to be permanent. Empirical results show evidence of mean reversion properties in European prices, though some minor differences arise from market to market that apparently, are not associated with the energy generation strategies followed by each country. Thus, it will likely be expected following the current energy shocks the series will recover due to natural market forces, without the need for additional policies

Quasars Clustering at z approx 3 on Scales less sim 10 h^{-1} Mpc

We test the hypothesis whether high redshift QSOs would preferentially appear in small groups or pairs, and if they are associated with massive, young clusters. We carried out a photometric search for \Ly emitters on scales $\lesssim 10 h^{-1}$ Mpc, in the fields of a sample of 47 $z\approx3$ known QSOs. Wide and narrow band filter color-magnitude diagrams were generated for each of the $6'.6\times6'.6$ fields. A total of 13 non resolved objects with a significant color excess were detected as QSO candidates at a redshift similar to that of the target. All the candidates are significantly fainter than the reference QSOs, with only 2 of them within 2 magnitudes of the central object. Follow-up spectroscopic observations have shown that 5, i.e., about 40% of the candidates, are QSOs at the same redshift of the target; 4 are QSOs at different z (two of them probably being a lensed pair at z = 1.47); 2 candidates are unresolved HII galaxies at z$\sim$0.3; one unclassified and one candidate turned out to be a CCD flaw. These data indicate that at least 10% of the QSOs at z$\sim$3 do have companions. We have also detected a number of resolved, rather bright \Ly Emitter Candidates. Most probably a large fraction of them might be bright galaxies with [OII] emission, at z$\approx$ 0.3. The fainter population of our candidates corresponds to the current expectations. Thus, there are no strong indication for the existence of an overdensity of \Ly galaxies brighter than m $\approx$ 25 around QSOs at $z\approx$ 3.Comment: 29 pages, 8 figures, tar gzip LaTex file, accepted to appear in Ap

Situacion del cultivo de frijol en America Latina

L.A. is the largest producer of field beans in the world (34 percent - av. of 3.85 million t/yr from 1968-71), Brazil alone accounting for more than 50 percent. Productivity is low, ranging from 330-1164 kg/ha (av 600 kg). Most of the beans are grown on small farms, often in association with other crops, especially maize. Cultural practices in the different countries are summarized. Tables show the frequency of diseases, pests (grouped according to type of damage caused) and weeds in the different L.A. countries and several regions of Brazil. Other important problems are poor rainfall distribution, the inefficiency of the marketing system and the lack of price controls. Research allocations are few and seed production policy does not have sufficient impact. Restructuration of national programs, training of research personnel and obtention of capital for greater credit facilities are recommended. On-farm studies should be conducted to determine the participation of beans as a source of income, nutrition and employment. (CIAT
