El teatre a les societats particulars de Barcelona durant els anys de la Primera Guerra Mundial (1914-1918). El CADCI i l’Ateneu Obrer del districte II

Aquest treball és una primera aproximació al magmàtic món del teatre societari barceloní de principis de segle XX. Vol ser una radiografia, primer, en forma d’estat de la qüestió general, i després, en forma d’anàlisi de dos casos concrets, el CADCI i l’Ateneu Obrer del districte II, de tots els aspectes que engloba el fet teatral en aquests espais: des dels repertoris al funcionament de les companyies, passant per la recepció, el paper del públic o la importància del teatre com a eina política i de transmissió generacional del coneixement. Tot això en el context d’uns anys de crisi del món teatral, en general, i del teatre català, en particular.

The role of Mexico in the first oil shortage: 1918-1922, an international perspective

In 1921 Mexico produced a quarter of world s petroleum, making the country the secondlargest producer in the world, but by 1930 it only accounted for 3 per cent of world sproduction. To date the discussion has mostly relied on events taking place in Mexico forexplaining the decline of the industry. Very little attention has been placed todevelopments in petroleum industry elsewhere, except Venezuela. Practically noattention has been paid to the reasons for the rise of oil output in Mexico. This neglectsthe massive changes taking place in the petroleum industry worldwide during the GreatWar years and its aftermath, and overall ignores the shortage of oil that occurred in theworld s markets between 1918-1921. These are crucial events in order to understand theearly rise of the Mexican oil industry and set the basis for a better understanding of thesubsequent sudden decline.

Morphometric relationhip in the Chaetognath Sagitta setosa Muller 1847: within population versus between population variability.

Sagitta setosa is a neritic Chaetognath exhibiting a discontinuous geographic distribution. To assess the influence of its discontinuous geographic distribution on morphometric variability between isolated populations, we conducted a biometric study of S. setosa from three different locations: Goteborg and Plymouth (North Atlantic) and Barcelona ( Western Mediterranean). Out results do indicate some disparity between the populations that is reflected not in size differences, largely determined by water temperature, but in shape (body proportions).
