Parasites in sympatric populations of native and invasive freshwater bivalves
2021
An increasing threat to local, native freshwater mussels (Unionida)—an ecologically important but globally alarmingly declining group— is the invasion by exotic bivalves. The Enemy Release Hypothesis predicts that introduced species should benefit from enemy-mediated competition because they are less likely to be harmed by natural enemies, such as parasites, than their native competitors. We investigated within-site differences in parasitism between sympatric native (tot. five spp.) and invasive (tot. three spp.) bivalves in eight northern European waterbodies, which harboured totally 15 parasite taxa. In paired comparisons using within-site averages, the mean number of parasite species in …
Toxicity assessment and biodegradation potential of water-soluble sludge containing 2,4,6-trinitrotoluen
2013
The water-soluble phase of trinitrotoluene-containing sludge (SLP) was characterized with regard to trinitrotoluene (TNT) concentration, ecotoxicity, and a model biodegradation experiment as evaluation criteria for further development of appropriate treatment technologies. SLP contained 67.8 mg TNT/l. The results of germination and root-elongation tests indicated that SLP had a species-specific phytotoxic effect. The results of a 21 day degradation experiment demonstrated TNT conversion to 4-amino-2,6-DNT and 2-amino-4,6-DNT, with a simultaneous reduction in the total concentration of nitroaromatics. Addition of inoculum stimulated the TNT degradation process. The presence of the sludge sol…
Uso della moneta presso gli Indigeni della Sicilia centro-meridionale
2011
The study of the coins found in the indigenous settlements of Caltanissetta province and the analysis of the related contexts of provenance, have highlighted that in these centers, still in the 4th century BC, the coin was considered a worthless piece of metal and that other bronze objects were used as medium of exchange. It is remarkable the discovery in this territory of three “mixed” hoards, including not only coins, but also of bronze scraps and small fragmentary objects. In this regard, the presence in this area of the so-called "monetary barbarizations" is interesting. They are rare specimens whose stylistic aspect, typological association, technical and, sometimes, even weight elemen…
The conservation of the environment in Ecuador's constitution
2017
The 2008 Ecuadorian Constitution is often presented as building on the local traditions of indigenous peoples in order to propose a non-anthropocentric approach to the conservation of the environment, based on the concept of buen vivir. After providing a short introduction on anthropocentric and non-anthropo-centric approaches to the environment, with attention to indigenous worldviews, this article attempts to: analyse the concept of buen vivir, appearing to have unclear boundaries; understand whether or not it is a concept derived from indigenous worldviews; and explore the innovative non-anthropocentric feature of the recognition of rights to the environment. Finally, the article uses th…

La maitrise du français écrit par les primo-arrivants : : une analyse des performances productives par frontière stochastique
2014
International audience; Cet article vise à déterminer les facteurs susceptibles d'expliquer le niveau de maîtrise du français écrit par les primo-arrivants en âge de travailler, sachant que peu de recherches ont été réalisées en France à ce sujet. L'originalité de cet article réside dans l'estimation d'une frontière stochastique de production afin d'expliquer les scores en français écrit des primo-arrivants (considérés comme producteurs de leurs propres compétences) et leurs performances productives. Les principaux résultats mettent en avant que la langue maternelle, l'âge au moment de l'immigration, le diplôme de la mère et la vie sociale sont des éléments qui influencent l'efficacité de c…
Wordarrows: El poder representativo del lenguaje en la obra de no ficción de N. Scott Momaday
2012
This article focuses on two non-fiction works by Native American author N. Scott Momaday: his 1969 historical memoir The Way to Rainy Mountain and his essay collection The Man Made of Words. It specifically tackles performative conceptions of language in the Kiowa storytelling tradition, where words are experienced as speech acts that have the power to intervene in surrounding realities. Taking into account 20th century ethno-cultural and linguistic policies in the United States, the article also reflects on the role indigenous languages may play in contemporary Native American Literature, which has most often been written in English.
Coinage and Indigenous Populations in Central Sicily
2015
The study of the coins found in the indigenous settlements of Caltanissetta province and the analysis of the related contexts of provenance, have highlighted that in these centers, still in the 4th century BC, the coin was considered a worthless piece of metal and that other bronze objects were used as medium of exchange. It is remarkable the discovery in this territory of three “mixed” hoards, including not only coins, but also of bronze scraps and small fragmentary objects. These elements seem to show a late achievement, among those communities, of an economy based on the exclusive use of coins, that was a peculiar expression of the Greek culture
Gli Indigeni e la moneta. Rinvenimenti monetali e associazioni contestuali dai centri dell’entroterra siciliano
2012
The Sicilian hinterland and, in particular, the territory of the current province of Caltanissetta, during the archaeological investigations of the last sixty years, has returned a substantial monetary documentation. The analysis of these coins, conducted in parallel with that of the materials found in the relative archaeological contexts, has allowed us to draw significant considerations on the "monetary uses" of the anellenic populations of this part of Sicily. Despite, starting from the last twenty-five years of the fifth century a. C., coins spread more and more in this territory, it seems that these communities never fully understood the original structure of this exchange instrument a…
