The Core ideas and axioms of classical fascism (1919-1945)

This article presents and explores the axioms and core ideas, or idées-force, of the Fascist ideologies of the first third of the twentieth century. The aim is to identify the features that define the term “Classical Fascism” as a conceptual category in the study of politics and to uncover the core ideas of its political theory. This analysis requires an appraisal of both the idées-force themselves and the political use that is made of them. If these appreciations are correct, Classical Fascism is characterized by a set of ideological and political aims and methods in which ideas, attitudes and behaviours are determined by an anti-democratic palingenetic ultranationalism underpinned by a sacralized ideology; the quest for a united, indissoluble society as apolitical system and, at the same time, the collective myth that mobilizes and redeems the nation; and third, violence as a political vehicle applied unchecked against internal opposition and against external enemies who challenge the nation´s progression towards the dream of rebirth and the culmination of this progression in the form of an empire.

Sapromyza lopesi sp. n. from Brazil: a species related to S. duodecimvittata (Frey, 1919) (Diptera: Lauxaniidae)

A new species, Sapromyza lopesi, is described from Brazil, and compared with its closest relative, S. duodecimvittata (Frey). Some remarks are made on the generic classification of South American Lauxaniidae as it affects these and other species.

Jaume Brossa (1868-1919) regeneracionista i revolucionari

Treball de recerca realitzat per una alumna d'ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l'any 2009. El present treball és un estudi de la personalitat humana, literària i filosòfica de Jaume Brossa així com un anàlisi del medi sociohistòric que li va tocar viure. El mètode utilitzat ha estat, en primer lloc, un rastreig de material original, articles publicats entre els anys 1892 i 1902 en diversos òrgans de premsa de Barcelona i Madrid. Una vegada obtingut el material requerit, s’ha sondejat per dins de les seves línies fins a trobar quin era el seu pensament en molts aspectes, a saber: el seu posicionament entorn els grans centres d’atenció del seu temps: el nacionalisme, el moviment obrer, l’estètica modernista en les seves parcel•les de música, literatura, teatre etc., tots aquests camps, tractats des de la base de la seva actitud regeneracionista i revolucionària. L’estudi s’ha realitzat des d’un enfocament crític: intentar esbrinar quines han estat les causes per les quals un autor certament notable de les nostres lletres ha estat marginat o, si més no, minimitzat en el seu abast intel•lectual. I, tal com es planteja al començament del treball, aquest consta d’una recerca de causes, implicacions, contextos etc. que ens permetin esbrinar per què Jaume Brossa ha estat desacreditat.

Les premiers lecteurs de Walras en Russie (1890-1919)

Cet article offre la première chronologie des lecteurs de Walras en Russie, entre 1890 et 1919. Ce panorama de la pensée économique russe est le résultat de recherches originales effectuées dans des bibliothèques en Russie, ainsi que quelques fonds d'archives. La plupart de ces informations sont en soi inédites. Elles ne constituent toutefois que des matériaux pour de subséquentes recherches, qui sont esquissées dans le commentaire final de cet article.

Distribuição Geográfica e Dispersão Alti-latitudinal de Alguns Gêneros e Espécies da Tribo Triatomini Jeannel, 1919 (Hemiptera, Reduviidae, Triatominae)

Geographical Distribution and Alti-latitudinal Dispersion of Some Genera and Species of the Tribe Triatomini Jeannel, 1919 (Hemiptera, Reduviidae, Triatominae) - With the currently known distribution of genera and species of the tribe Triatomini Jeannel, 1919, maps and diagrams were prepared, showing the geographical area occupied by the species and their respective dispersion in grades of latitude and altitude. Two genera are not treated: Panstrongylus Berg, 1879, already published and Triatoma Laporte, 1832, that is being published partially in several articles. Genus Eratyrus Stal, 1859, has two species, while Dipetalogaster Usinger, 1939, Mepraia Mazza, Gajardo & Joerg, 1940, Paratriatoma Barber, 1938 and recently created genus Hermanlentia Jurberg & Galvão, 1997, have only one each. The study of these maps and diagrams permits a better knowledge about some ecological requirements of Chagas' disease vectors and detects gaps in the geographical distribution, where the species were not found but probably they could be prevalent

Ciclo biológico em laboratório de Rhodnius brethesi Matta, 1919 (Hemiptera, Reduviidae, Triatominae), potencial vetor silvestre da doença de Chagas na Amazônia

R. brethesi is a sylvatic species from the Amazon region; it has been incriminated as responsible for the transmission of Chagas disease in collectors of piaçaba in this region. The aim of present study was to investigate the efficiency of these insects as potential vectors of Trypanosoma cruzi. Aspects related with feeding and defecation patterns, life time, and mortality had been observed in each instar of R. brethesi. We use 5th instar nymphs to get adults virgins, after the moulting 3 groups with 6 females and 2 males each were created to obtain eggs. After hatching, 1st instar nymphs had been weighed and kept in bottles until the next moult. Insects were fed once a week in mice. Results showed that the average period of incubation was 17 days, the number of blood meal was increasing from the 1st to the 5th instar nymph with 7 (average) to become adult, a significative numbers of the defecations occurring immediately after the bloodmeals. The total percentual of mortality was 16%. This results suggests that this species presents a good exploitation of blood meals and a brief nymphal development in laboratory conditions reflecting its behavior in sylvatic environments.

Morphobiological aspects of Rhodnius brethesi Matta, 1919 (Hemiptera:Reduviidae) from the Upper and Middle Negro River, Amazon region of Brazil: I - scanning electron microscopy

The occurrence of autochthonous cases of Chagas disease in the Amazon region of Brazil over recent decades has motivated an intensification of studies in this area. Different species of triatomines have been identified, and ten of these have be proven to be carriers of the parasite Trypanosoma cruzi or " cruzi-like " parasites. Studies conducted in the municipalities of Santa Isabel do Rio Negro and Barcelos, located on the Upper and Middle of the Negro River, microregion of Negro River, state of Amazonas have confirmed not only that Rhodnius brethesi is present in the palm tree Leopoldinia piassaba, but also that this insect was recognized by palm fiber collectors. A morphological study of eyes, inter-ocular and inter-ocellar regions, antennae, buccula, labrum, rostrum, stridulatory sulcus and feet, including the apex of the tibia, spongy fossette and ctenidium was conducted by scanning electron microscopy. The buccula and the stridulatory sulcus presented notable differences in specimens of different genera and also of different species. These data make it possible to suggest that the details presented in these structures can be included as diagnostic characteristics to be used in new dichotomous keys, thereby contributing towards studies of taxonomy and systematics and furnishing backing for comparative analysis of specimens collected from different localities.
