El Crecimiento en el Paraguay: ¿favorable a los pobres?

En aquest treball es revisen els principals corrents teòrics dins de la literatura del "creixement favorable als pobres" ("pro-poor growth"). L'objectiu és analitzar el patró del creixement a Paraguai durant la dècada 1997-2007. S'analitza si el creixement de l'economia paraguaiana ha estat, o no, favorable als pobres. Els resultats, a partir d'enquestes de llars, llancen un panorama descoratjador. En les recessions, el creixement és favorable als pobres però en termes relatius i no en termes absoluts, el que impedeix reduir la pobresa. En les expansions, el creixement els resulta directament desfavorable.

The political ecology of Jatropha plantations for biodiesel in Tamil Nadu, India

Jatropha curcas is promoted internationally for its presumed agronomic viability in marginal lands, economic returns for small farmers, and lack of competition with food crops. However, empirical results from a study in southern India revealed that Jatropha cultivation, even on agricultural lands, is neither profitable, nor pro-poor. We use a political ecology framework to analyze both the discourse promoting Jatropha cultivation and its empirical consequences. We deconstruct the shaky premises of the dominant discourse of Jatropha as a “pro-poor” and “pro-wasteland” development crop, a discourse that paints a win-win picture between poverty alleviation, natural resource regeneration, and energy security goals. We then draw from field-work on Jatropha plantations in the state of Tamil Nadu to show how Jatropha cultivation favors resource-rich farmers, while possibly reinforcing existing processes of marginalization of small and marginal farmers.

"Pro crosis argenti". La plata al comtat de les Muntanyes de Prades: explotació, gestió i rendiment de les mines de Falset durant la baixa edat mitjana

L’objectiu de la recerca que s’ha dut a terme durant el període 2004-2007 ha estat analitzar les característiques territorials, senyorials i jurisdiccionals del domini format pel comtat de les Muntanyes de Prades i la baronia d’Entença i, a partir d’aquí, aprofundir en un aspecte concret d’aquesta senyoria: l’explotació minera de l’argent durant els segles XIV i XV. En aquest sentit, la recerca s’ha fonamentat en l’estudi de la documentació relacionada amb aquesta qüestió que hi ha dipositada a l’Arxiu Ducal de Medinaceli; la qual, però, s’ha pogut buidar i analitzar a través de la consulta de les còpies microfilmades que se’n conserven al Monestir de Poblet. Com a resultats principals s’ha aconseguit delimitar territorialment el comtat de les Muntanyes de Prades i baronia d’Entença i determinar-ne la titularitat jurisdiccional a mitjan segle XIV. A més, s’han establert els paràmetres que marquen i expliquen l’evolució de la normativa que regulava l’explotació minera de l’argent. I, finalment, s’ha pogut determinar que, segurament, la major part de l’argent produït a mitjan segle XIV es va obtenir a partir de minerals d’argent i argent natiu.

Generation of cardiomyocytes from new human embrionic stem cell lines derived from poor-quanlity blastocysts

Human embryonic stem (hES) cells represent a potential source for cell replacement therapy of many degenerative diseases. Most frequently, hES cell lines are derived from surplus embryos from assisted reproduction cycles, independent of their quality or morphology. Here, we show that hES cell lines can be obtained from poor-quality blastocysts with the same efficiency as that obtained from good- or intermediate-quality blastocysts. Furthermore, we show that the self-renewal, pluripotency, and differentiation ability of hES cell lines derived from either source are comparable. Finally, we present a simple and reproducible embryoid body-based protocol for the differentiation of hES cells into functional cardiomyocytes. The five new hES cell lines derived here should widen the spectrum of available resources for investigating the biology of hES cells and advancing toward efficient strategies of regenerative medicine.

Aplicación de recomendaciones en pro de la alineación entre competencias-metodología-evaluación en asignaturas de ingeniería telemática.

Este trabajo recoge la experiencia llevada a cabo en tres asignaturas en cuanto a la aplicación de recomendaciones (acciones) dirigidas a la mejora de la alineación entre las competencias planteadas en los respectivos planes docentes, la metodología para trabajarlas y evaluación de las mismas. Concretamente las asignaturas que han puesto en marcha estas recomendaciones pertenecen a la Universidad Pompeu Fabra (una asignatura) y a la Universidad de Valladolid (las otras dos) todas pertenecientes al área de Ingeniería Telemática. Además de incluir una breve descripción de las recomendaciones aplicadas se presenta el contexto de cada caso (características básicas de las asignaturas), el proceso seguido durante su aplicación así como la evaluación llevada a cabo (tanto durante el proceso de aplicacióncomo al finalizar) para conocer el nivel de satisfacción tanto del colectivo discente como del docente. Finalmente se incluyen las reflexiones realizadas en forma de conclusiones que giran entorno a dos ejes: el primero de ellos es el impacto de la aplicación de las recomendaciones en la calidad de la función docente y el segundo hace referencia al aumento de la visibilidad de esta relación desde la perspectiva discente y las repercusiones en su proceso de aprendizaje.

Poor, Hungry and Stupid: Numeracy and the Impact of High Food Prices in Industrializing Britain, 1780-1850

This paper argues that low levels of nutrition impaired cognitive development in industrializing England, and that welfare transfers mitigated the adverse effects of high food prices. Age heaping is used as an indicator of numeracy, as derived from census data. For the cohorts from 1780-1850, we analyse the effect of high grain prices during the Napoleonic Wars. We show that numeracy declined markedly for those born during the war years, especially when wheat was dear. Crucially, where the Old Poor Law provided for generous relief payments, the adverse impact of high prices for foodstuffs was mitigated. Finally, we show some tentative evidence that Englishmen born in areas with low income support selected into occupations with lower cognitive requirements.

Common law and civil law as pro-market adaptations

We argue that in the development of the Western legal system, cognitive departures are themain determinant of the optimal degree of judicial rule-making. Judicial discretion, seen here as the main distinguishing feature between both legal systems, is introduced in civil law jurisdictions to protect, rather than to limit, freedom of contract against potential judicial backlash. Such protection was unnecessary in common law countries, where free-market relations enjoyed safer judicial ground mainly due to their relatively gradual evolution, their reliance on practitioners as judges, and the earlier development of institutional checks and balances that supported private property rights. In our framework, differences in costs and benefits associated with self-interest and lack of information require a cognitive failure to be active.

The effects of poor financial information systems on the long term sustainability of local public services. Empirical evidence from the Catalan Municipalities

In this paper we describe the existence of financial illusion in public accountingand we comment on its effects for the future sustainability of local publicservices. We relate these features to the lack of incentives amongst publicmanagers for improving the financial reporting and thus management of publicassets. Financial illusion pays off for politicians and managers since it allowsfor larger public expenditure increases and managerial slack, these beingarguments in their utility functions. This preference is strengthen by the shorttime perspective of politically appointed public managers. Both factors runagainst public accountability. This hypothesis is tested for Spain by using anunique sample. We take data from around forty Catalan local authorities withpopulation above 20,000 for the financial years 1993-98. We build this databasis from the Catalan Auditing Office Reports in a way that it can be linkedto some other local social and economic variables in order to test ourassumptions. The results confirm that there is a statistical relationship between the financialillusion index (FI as constructed in the paper) and higher current expenditure.This reflects on important overruns and increases of the delay in payingsuppliers, as well as on a higher difficulties to face capital finance. Mechanismsfor FI creation have to do among other factors, with delays in paying suppliers(and thereafter higher future financial costs per unit of service), no adequateprovision for bad debts and lack of appropriate capital funding either forreposition or for new equipments. For this, it is crucial to monitor the way inwhich capital transfers are accounted in local public sheet balances. As a result,for most of the Municipalities we analyse, the funds for guaranteeing continuityand sustainability of public services provision are today at risk.Given managerial incentives at present in public institutions, we conclude thatpublic regulation recently enforced for assuring better information systems inlocal public management may not be enough to change the current state of affairs.

The poor stay poor: Non-convergence across countries and regions

We study the issue of income convergence across countries and regions witha Bayesian estimator which allows us to use information in an efficient andflexible way. We argue that the very slow convergence rates to a commonlevel of per-capita income found, e.g., by Barro and Xavier Sala-i-Martin,is due to a 'fixed effect bias' that their cross-sectional analysisintroduces in the results. Our approach permits the estimation of differentconvergence rates to different steady states for each cross sectional unit.When this diversity is allowed, we find that convergence of each unit to(its own) steady state income level is much faster than previously estimatedbut that cross sectional differences persist: inequalities will only bereduced by a small amount by the passage of time. The cross countrydistribution of the steady state is largely explained by the cross countrydistribution of initial conditions.

Poor, hungry and ignorant: Numeracy and the impact of high food prices in industrializing Britain, 1780-1850

This paper uses the ability to recall one s age correctly as an indicator of numeracy.We show that low levels of nutrition impaired numeracy in industrializing England, 1780-1850.Numeracy declined markedly among those born during the war years, especially where wheatwas dear. England s nascent welfare state mitigated the negative effect of high food prices oncognitive skills. Nutrition during early development mattered for labor market outcomes:individuals born in periods or countries with high age heaping were more likely to sort intooccupations with limited intellectual requirements.

Do interregional transfers improve the economic performance of poor regions? The case of Spain

The 17 regional governments of Spain receive grants from both thecentral government and the European Union. The grants are generallyredistributive and are intended to stimulate economic activity inthe poorer regions. We evaluate the effectiveness of the grants bycomparing the economic performance of the regions before and afterthe implementation of the grant programs using a differences--in--differences approach. We find that these policies have not beeneffective at stimulating private investment or improving the overalleconomies of the poorer regions.
