Revision of Sarcocornia (Chenopodiaceae) in South Africa, Namibia and Mozambique

2010

Abstract Sarcocornia comprises ca. 20–24 perennial, halophytic herb and shrub species. The genus is distinct from other genera in the Salicornioideae in having flowers that are more or less equal in size, arranged in a row, and with seeds that have a membranous hairy testa and lack perisperm. Sarcocornia is distributed worldwide, mainly in regions characterized by warm-temperate and, to a lesser extent, subtropical climates. The representatives of this genus are found in habitats such as estuarine salt marshes, tidal mud flats, coastal cliffs, inland salt pans, and salt-laden alluvia of intermittent semi-desert and desert streams. Some South African taxa also occur in inland (semi-desert) q…

Geomorphological evolution of the River Loukkos estuary around the Phoenician city of Lixus on the Atlantic Littoral of Morocco

2009

The ancient city of Lixus, today situated on a hill on the right bank of the River Loukkos, 4km from the coast, was founded on the shore of a brackish lagoon that was sheltered from Atlantic storms. This geographical context provided the city with one of the best Phoenician harbors and abundant fishing resources, and allowed access to the Gharb cattle farming resources and cereal production systems. In this study, the historical evolution of the Loukkos estuarine environment is reconstructed through geomorphological and sedimentological analyses, combined with cartographic, archaeological, and geographical data. The outcomes reveal the progressive infilling of the estuarine lagoon of Lixus …

La critica di Piero Sraffa alla teoria marshalliana del valore negli anni venti. Una prospettiva metodologica

1998

Il saggio intende ricostruire la logica della ricerca scientifica del giovane Sraffa così come essa emerge dall'analisi degli articoli del 1925-26. I risultati che emergono si possono così riassumere. La critica di Sraffa alla teoria marshalliana del valore non è una critica di tipo logico in senso stretto: il che muove Sraffa non è quello di mettere in luce l'esistenza di alcuni non sequitur all'interno della costruzione teorica marshalliana; bensì di dimostrare che la portata empirica del modello marshalliano, una volta ricostruito in modo logicamente coerente, è ben più ristretta diquanto generalmente ammesso.

Soil chemical and biochemical properties of a salt-marsh alluvial Spanish area after long-term reclamation

2009

Marisma, one of the largest salt-marsh alluvial areas in SW Spain, has been reclaimed since 1970 by artificial drainage and amendment with phosphogypsum (PG) so as to reduce Na+ saturation. Within the reclaimed area, two 250- × 20-m plots were treated as follows: (1) amendment with 25 Mg/ha of PG every 2 to 3 years between 1979 and 2003 (plot PY); (2) like PY but PG treatment stopped after 1997 (plot DR). A contiguous virgin Marisma salt-marsh plot (MV), neither drained nor amended, was the control. In MV, soil microbial biomass C, most enzyme activities and total organic C content were much greater than in PY and DR soils, despite the salinity stress. The decrease in soil organic matter co…

Method and analysis in Piero Sraffa's 1925 critique of Marshallian economics

2000

This paper provides an analysis of the logical structure and analytical content of Piero Sraffa's 1925 Italian paper, ‘Sulle relazioni fra costo e quantita prodotta’. It shows that Sraffa's criticism of the supply side of Marshall's theory of value in a competitive partial equilibrium model involves analytical and methodological issues. Endorsing an agressive methodology Sraffa logically reconstructs Marshall's model on variable returns to determine its empirical domain. He demonstrates that the latter encompasses only the empirically irrelevant cases of specific factor industries and specific external economies industries and that it cannot be generalized to non-specific factor industries …

Les minières de silex néolithiques des marais de Saint-Gond (Marne)

2014

In the southern and eastern area of the Côte d’Île-de-France, north of the marshes of Saint-Gond (Marne, France), research incorporating a great deal of unpublished documentation, and the results of pedestrian and aerial surveys, has highlighted five flint mines. For various reasons, the many indications of mining activity in this region have never been considered sufficient to consider it a mining area, however, the combination of a series of objective observations suggests the existence of five flint mines.In several sites, flint mining was conducted from shafts several metres deep, sometimes connected by galleries. As many archaeological discoveries made during the earlier excavations ha…
