Soil fungal community composition does not alter along a latitudinal gradient through the maritime and sub-Antarctic

2012

We investigated the relationships between fungal community composition, latitude and a range of physicochemical parameters in 58 soils sampled from a 2370 km latitudinal gradient between South Georgia (54 S, 38 W) in the sub-Antarctic and Mars Oasis (72 S, 68 W) on Alexander Island in the southern maritime Antarctic. Our study, which is based on approximately ten times the number of samples used in previous similar studies, indicates that latitude and its associated environmental parameters are not related to fungal community composition. Significant changes in the composition of soil fungal communities were observed in relation to gradients of the ratio of total organic carbon to nitrogen,…

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…

Translation and terminology. Apropos of two Spanish versions of Dumarsais’ Logique (Madrid, 1800)

2013

Framed in the field of philosophical translation (lato sensu), this article deals with two different versions of Dumarsais’ Logique ([1769] 1797, Paris), both published in Madrid in 1800. We argue that these two Lógicas, which were translated by two different persons, had distinct purposes. This is evidenced by their respective bibliographical contexts and metatexts and by their translators’ use of different sets of Spanish terminological equivalents for the concepts that, as set out in the first few pages of his Logique, are key in Dumarsais’ theory of knowledge. In the first of these translations, which envisions logic as having an introductory role in the acquisition of scientific knowle…

Traduction et terminologie. A propos de deux versions espagnoles (Madrid, 1800) de la Logique de Dumarsais

2013

Cette étude qui relève du domaine de la traduction philosophique (lato sensu) a pour objet deux versions de la Logique de Dumarsais ([1769]1797) éditées en Espagne (1800). Nous montrons que ces deux Lógicas, oeuvres de deux traducteurs différents, qui eurent chacun des fins également différentes, comme le prouvent le contexte bibliographique et les métatextes respectifs, manifestent la présence d’une terminologie espagnole divergente pour les termes clé de la théorie de la connaissance que l’auteur français exposa dans les pages initiales de sa Logique. La première de ces traductions, qui attribue à la logique un rôle d’introduction aux sciences, choisit des termes systématiquement calqués …

Ontological representation of texts, and its applicationsin text analysis

2003

Masteroppgave i informasjons- og kommunikasjonsteknologi 2003 - Høgskolen i Agder, Grimstad For the management of a company, the need to know what people think of their products or services is becoming increasingly important in an increasingly competitive market. As the Internet can nearly be described as a digital mirror of events in the ”real“ world, being able to make sense of the semi structured nature of natural language texts published in this ubiquitous medium has received growing interest. The approach proposed in the thesis combines natural language processing and ontologies to represent elements in texts and relations between them. These relations are used to determine what terms …

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 …
