Origin of a restraining bend in an evolving strike-slip system: The Cenozoic As Pontes basin (NW Spain)

The As Pontes basin (12 km2), NW Iberian Peninsula, is bounded by a double restraining bend of a dextral strike-slip fault, which is related to the western onshore end of the Pyrenean belt. Surface and subsurface data obtained from intensive coal exploration and mining in the basin since the 1960s together with additional structural and stratigraphic sequence analysis allowed us to determine the geometric relationships between tectonic structures and stratigraphic markers. The small size of the basin and the large amount of quality data make the As Pontes basin a unique natural laboratory for improving our understanding of the origin and evolution of restraining bends. The double restraining bend is the end stage of the structural evolution of a compressive underlapping stepover, where the basin was formed. During the first stage (stepover stage), which began ca. 30 Ma ago (latest Rupelian) and lasted 3.4 My, two small isolated basins bounded by thrusts and normal faults were formed. For 1.3 My, the strike-slip faults, which defined the stepover, grew towards each other until joining and forming the double restraining bend, which bounds one large As Pontes basin (transition stage). The history of the basin was controlled by the activity of the double restraining bend for a further 3.4 My (restraining bend stage) and ended in mid-Aquitanian times (ca. 22 Ma).

Foreign trade traps in the european periphery: Spain, 1870-1913

In this article we research into the difficulties that foreign trade imposed onSpanish process of integration into the international economy in the years priorto the First World War. We start out by examining some features of the foreigntrade structure of the country. By means of an econometric analysis of importand export series, it is possible to observe the presence of a trend towards tradedeficit, which was in force when Spain grew at a rate similar to that of itstrading partners. We also check that, in the absence of these compensatorymechanisms, adjustment in foreign payments could be reached by means ofprotective measures and the exchange rate.

Were Spanish migrants attracted by industrial agglomerations?: an analysis for the interwar years in the light of the new economic geography

In this paper we examine whether access to markets had a significant influence onmigration choices of Spanish internal migrants in the inter-war years. We perform astructural contrast of a New Economic Geography model that focus on the forwardlinkage that links workers location choice with the geography of industrial production,one of the centripetal forces that drive agglomeration in the NEG models. The resultshighlight the presence of this forward linkage in the Spanish economy of the inter-warperiod. That is, we prove the existence of a direct relation between workers¿ localizationdecisions and the market potential of the host regions. In addition, the direct estimationof the values associated with key parameters in the NEG model allows us to simulatethe migratory flows derived from different scenarios of the relative size of regions andthe distances between them. We show that in Spain the power of attraction of theagglomerations grew as they increased in size, but the high elasticity estimated for themigration costs reduced the intensity of the migratory flows. This could help to explainthe apparently low intensity of internal migrations in Spain until its upsurge during the1920s. This also explains the geography of migrations in Spain during this period,which hardly affected the regions furthest from the large industrial agglomerations (i.e.,regions such as Andalusia, Estremadura and Castile-La Mancha) but had an intenseeffect on the provinces nearest to the principal centres of industrial development.

Selenium uptake by edible plants from enriched peat.

As a constituent of selenoproteins, selenium (Se) is considered an essential element for human health.The main way that Se enters the body is via the consumption of vegetables, whose concentration of thiselement depends on soil Se content. We grew cabbage, lettuce, chard and parsley, in peat enriched in Seby means of the additive Selcote Ultra®and Na2SeO3and Na2SeO4. Total Se in plants was determinedby acidic digestion and Se speciation by an enzymatic extraction. Both were measured by ICP/MS. Theconcentration ranges were between 0.1 mg Se kg−1and 30 mg Se kg−1for plants grown in Selcote Ultra®media, and between 0.4 mg Se kg−1and 1606 mg Se kg−1for those grown in peat enriched with Se sodiumsalts. We found Se (IV), Se (VI) and SeMet in all the extracts. Peat fortified with Selcote Ultra®gave slightlyhigher Se concentration than natural content values. For plants grown with selenium sodium salts, Secontent increases with the Se added and part of the inorganic Se was converted mainly to SeMet. A highSe fortification can damage or inhibit plant growth. Cabbage showed the greatest tolerance to Se.

Gifts of Mars: Warfare and Europe's early rise to riches

Today, per capita income differences around the globe are large ? varying by as much as a factor of 35 across countries (Hall and Jones 1999). These differentials mostly reflect the "Great Divergence" (Sam Huntingon) ? the fact that Western Europe and former European colonies grew rapidly after 1800, while other countries grew much later or stagnated. What is less well-known is that a "First Divergence" preceded the Great Divergence: Western Europe surged ahead of the rest of the world long before technological growth became rapid. Europe in 1500 was already twice as rich on a per capita basis as Africa, and one-third richer than most of Asia (Maddison 2007). In this essay, we explain how Europe's tumultuous politics and deadly penchant for warfare translated into a sustained advantage in per capita incomes.

La trampa de Rousseau. O com es pot saltar del convencionalisme al civisme

En aquest text es presenta una lectura de Rousseau des de la seva dimensió política i sota una perspectiva d’actualitat. Amb una aproximació a la concepció i l’argumentació dels elements que conformen el projecte polític en l’obra El contracte social —això és, justícia, moral i raó— les autores pensen a fons la modernitat des de l’assumpció del convencionalisme cívic liberal. L’espai públic és, doncs, l’eix que permet desgranar els arguments que condicionen un ésser humà que es desplega molt més enllà de la naturalesa i que donen sentit a una educació conscient d’una de les seves finalitats intrínseques més rellevants.

Per un patrimoni conceptual de J.-J. Rousseau

Més enllà de les controvèrsies sobre l’obra de Jean-Jacques Rousseau, el cert és que la seva obra i la mitologia que al seu entorn s’ha construït formen part del que podríem anomenar el patrimoni conceptual de la pedagogia.1 Escrits i idees, matèria i pensament, però també proposta i resposta, formarien, per tant, l’elenc dels elements a l’entorn de la seva figura als quals s’ha atorgat valor. Tres elements que, en si mateixos, representen una aportació a la pedagogia, tant per allò que s’esdevingué com per les reaccions que provocà. De tal manera que bé podem afirmar que aquest autor esdevé com un dels fonaments de la memòria pedagògica. En aquest sentit, no és estrany que, en ocasió del tricentenari del seu naixement, hagin estat diverses les iniciatives per a la difusió de la seva biografia, del seu pensament i, també, del deixant que les seves propostes han tingut.

Presència de Rousseau a Catalunya: entre el mite i la realitat

En aquest article s’ofereix un perfil del pensament de Rousseau a partir de la seva relació amb la filosofia estoica i la seva dependència respecte de les idees de Montaigne, alhora que es remarca —atenint-se a la Professió de fe del vicari savoià— la dimensió religiosa i espiritual de la seva cosmovisió. Sobre la base d’aquests supòsits es revisa l’impacte de les idees de Rousseau en el Romanticisme del segle xix, sense perdre de vista les crítiques que la seva pedagogia va merèixer dels ideòlegs del Noucentisme (Eugeni d’Ors, Joaquim Xirau). Finalment, es conclou que la presència de la pedagogia de Rousseau en el Moviment de Renovació Pedagògica, viscut durant les primeres dècades del segle xx a Catalunya, constitueix més un horitzó que no pas una realitat bastida sistemàticament i sòlidament.

Sectoral and occupational employment growth in Spain 1995-2005

Between 1995 and 2005, the Spanish economy grew at an annual average rate higher than 3,5%. Total employment increased by more than 4.9 millions. Most of this growth was in occupations related with university degrees (more than 890,000, 18% of the total employment increase) and vocational qualifications (more than 855,000, 17.5% of the total employment increase). From a sectoral perspective, the main part of this increase took place in “Real estate, renting and business activities” (K sector in NACE rev.1), “Construction” (F sector) and “Health and social sector” (N sector). This paper analyses this employment growth in an Input-output framework, by means of a structural decomposition analysis (SDA). Two kinds of results have been obtained. From a sectoral perspective we decompose employment growth into Labour requirements change, technical change and demand change. From an occupational perspective, we decompose the employment growth in substitutions effect, labour productivity effect and demand effect. The results show that, in aggregated terms, the main part of this growth is attributable to demand growth, with a small technical improvement. But the results also show that this aggregated behaviour hides important sectoral and occupational variation. The purpose of this paper is to contribute to the ongoing debate over productivity growth and what has been called the “growth model” for the Spanish economy.

Gone with the Wind and the Southern Way of Life: the Civil War as described in Margaret Mitchell’s Novel

This essay examines the American Civil War of 1861 – 1865, which is also known as the bloodiest war that the United States has ever experienced. The pretext for the war was the abolition of slavery in the South, and after many battles the Southern states lost: as a consequence, they experienced major changes in their economic and social life. This interesting piece from American history can be traced out throughout the characters’ lives in the novel Gone with the Wind which has been thoroughly analyzed in order to draw nearer and to comprehend the changes in the Southern way of life before and after the war. The author, Margaret Mitchell, was born in Atlanta, Georgia, and grew up with the stories about the war. As a result, Gone with the Wind studies not only its causes, but also the years after its end – a period which is not generally a subject of history and receives little attention – and the effects that such reversals have on former planters and slaves. From the position of contemporaneity, the reader can see that such changes in a society do not end with the laying down of an act, or in this case the end of the war, but they continue during many years; thus, the modern world can draw conclusions and lessons for events that are happening at the moment.
