The authors present here a list of 32 mosses belonging to 15 families: Brachytheciaceae, Cryphaeaceae, Entodontaceae, Hedwigiaceae, Hypnaceae, Leptodontaceae, Meteoriaceae, Neckeraceae, Pilotrichaceae, Polytrichaceae, Pterobryaceae, Racopilaceae, Rigodiaceae, Stereophyllaceae, and Trachypodaceae, all collected in the mountainous forests of the Yungas of the NW of the Argentina (Jujuy, Salta, Catamarca and Tucumán provinces), and also in the rainforests from the NE of the country (Misiones province). Eight species: Atrichum polycarpum, Chrysohypnum elegantulum, Pilosium chlorophyllum, Pilotrichella flexilis, Porotrichodendron lindigii, Pseudotrachypus martinicensis, Steerecleus scariosus, and Thamnobryum fasciculatum are new records for the bryologic flora from Argentina. Braunia imberbis and Squamidium brasiliense are two new records for the bryophytic flora of the Catamarca province; Porotrichodendron superbum is new for the Salta province, while Forsstroemia coronata is the first record for the Catamarca and Jujuy provinces. Aerolindigia capillacea, Braunia reflexifolia, Chryso-hypnum diminutivum, Meteorium deppei and Meteoridium remotifolium are five new citations for the Jujuy province, and Schoenobryum concavifolium is new for the bryophytic flora of the Misiones province. Many studied species occur more frequently in the Yungas than in the NE rainforests; others show separated distribution but live in both areas, the Yungas and Paranaense area, and others are more or less restricted to the Paranaense rainforest of the NE of Argentina. The taxonomy of species is updated, and comments are included on bibliographical precedents, ecology and chorology of each taxon.

Canna tandilensis is proposed as a species new to science. Plants grow wild terrestrial, in rocky places exposed to solar radiation forming dense colonies whose individuals of small to medium length, produce reduced inflorescences with large and few yellow to bright orange flowers and narrow and reflexed staminodes. The specific epithet refers to the city of Tandil at the south of Buenos Aires Province where the holotype comes from. It is related to other species having reduced inflorescences, narrow leaves and staminodes, and nectar guides in androecium pieces such as C. lineata. A detailed description of the new species is given, along with a study of the morphological vegetative and floral characters. These characters were compared with those from two other species C. glauca and C. lineata. According to these new evidences two groups of similar species of the genus are suggested. The number of species surveyed until now in Argentina rises to sixteen.

The transition from a positivist matrix to an idealistic one in Argentinean academic philosophy can be read as a result of a gradual and problematic pollution. It was, also, heavily traversed by considerations that exceeded the theoretical aspects. Based on the willingness to explore this transit, the article pays attention to one of the episodes of this contamination: how the Revista de Filosofía reads Croce and Gentile’s philosophy. Observing there some possibility of dialogue between positivist assumptions, with which the journal takes a position, and the idealism the article analyze how this dialogue and its limits were given from a political consideration. If the idealism was condemned, it is centrally owed to its performance during the first years of the government of Mussolini. If, meanwhile, it was some to rescue of that philosophy, it was that it contributed to think the revolutionary change.

The aim of this article is to analyze the social policy in Latin America in a context of emerging welfare states. To understand the changes one takes into consideration the theories about institutional reform and the transformations produced in the XX century and the beginning of the XXI to substitute a social security regime mainly based on segmentation of benefi ts and on programs to fi ght poverty by another with an institutional and redistributive nature. The paper pays attention in particular to the path of the most developed welfare states of Latin America: Costa Rica, Chile, Argentina, Brasil y Uruguay.

Los indicadores de sostenibilidad conforman herramientas útiles para la toma de decisiones. Las ciudades latinoamericanas, y especialmente las áreas de expansión sin planificación adecuada, enfrentan desafíos cada vez mayores para revertir problemáticas que amenazan su sostenibilidad. El presente trabajo evalúa de manera preliminar, la sostenibilidad ambiental del periurbano de Mar del Plata (Argentina) tomando como referencia algunos de los indicadores propuestos por el modelo del Banco Interamericano de Desarrollo en la Iniciativa Ciudades Emergentes y Sostenibles. Se construyó un índice sintético (Índice de Sostenibilidad Ambiental, ISA) que integra trece indicadores agrupados en ocho temas. Las situaciones más críticas (ISA: 0,45-0,558) se identifican fundamentalmente en zonas en las que se desarrollan actividades rurales y en las que se localizan asentamientos de carácter precario. El estudio realizado profundiza en el conocimiento de la dimensión ambiental de la sostenibilidad, enfatizando en el análisis de los contrastes internos del periurbano marplatense.

Desde tiempos de José Carlos Mariátegui, la crítica literaria indigenista viene articulando un discurso etnocentrista cuyo eje de producción se sitúa en Perú y los países vecinos, pero rara vez se ha mencionado una obra argentina que trate sobre las desigualdades que sufren los indígenas de ese país. Ni siquiera la academia argentina ha analizado ninguna novela desde la óptica indigenista.En un país cuyos gobiernos, desde el siglo XIX, han tratado de borrar cualquier traza de sangre indígena en su población, ya sea mediante la asimilación, exterminio o invisibilidad, y cuyas zonas de mayor asentamiento indígena se encuentran lejos del hegemónico Buenos Aires, las narraciones de problemas sociales ajenos quedaban encajonadas en el recóndito mundo de la literatura regional.Sin embargo, durante los años de eclosión del movimiento indigenista, escritores argentinos se hicieron eco de los sufrimientos y demandas de sus compatriotas indígenas por medio de novelas que sobrepasaron el peyorativo epíteto regionalista y que incomprensiblemente, han sido olvidadas.En este artículo, que forma parte de un estudio más amplio, se aborda el silencio crítico, se contextualiza la producción indigenista de la época y se analizan brevemente algunas de las obras.

This article analyzes how Lorca develops the concept of ‘duende’, finding a crucial missing link in the Elogio de Antonia Mercé, ‘la Argentina (1930). ‘Duende’ crystallizes around 1929/1930 when the poet explicitly takes into account the art of the dancer in performance. Three aspects of performance are singled out and systematically traced through Lorca's evolving reflections on popular art and the struggle of the modern artist to create the new – from his first lecture on the cante jondo in 1922 to the Arquitectura del cante jondo (1930) and finally Juego y teoría del duende (1933). The conclusion is drawn that it is in the performance and reception of a text – whether it is heard or read – that the artist's agonistic stand between tradition and modernity, repetition and singularity, is played out, in an invitation to the listener or reader to celebrate his or her mortality.

Inventories and vertical distribution of (137)Cs were determined in La Plata region undisturbed soils, Argentina. A mean inventory value of 891 ± 220 Bq/m(2) was established, which is compatible with the values expected from atmospheric weapon tests fallout. The study was complemented with pH, organic carbon fraction, texture and mineralogical soil analyses. Putting together Southern Hemisphere (137)Cs inventory data, it is possible to correlate these data with the mean annual precipitations. The large differences in (137)Cs concentration profiles were attributed to soil properties, especially the clay content and the pH values. A convection-dispersion model with irreversible retention was used to fit the activity concentration profiles. The obtained effective diffusion coefficient and effective convection velocity parameters values were in the range from 0.2 cm(2)/y to 0.4 cm(2)/y and from 0.23 cm/y to 0.43 cm/y, respectively. These data are in agreement with values reported in literature. In general, with the growth of clay content in the soil, there was an increase in the transfer rate from free to bound state. Finally, the highest transfer rate from free to bound state was obtained for soil pH value equal to 8.

A vaga de democratizações que teve lugar na América Latina na década de 1980 e 1990 alterou profundamente a paisagem política do Cone Sul, pondo fim a diversos regimes autoritários naquela região. O Chile, dirigido de forma autoritária pelo general Augusto Pinochet desde 1973, foi um dos últimos países onde a transição democrática aconteceu. O processo que teve início com o plebiscito de 1988 culminou com a eleição de Patricio Aylwin, a 11 de Março de 1990 e não foi resultado apenas de esforços internos. Este estudo centra-se na dimensão internacional desse processo. Uma vez que as escassas investigações sobre esta vertente se focam no papel de grandes potências, como os Estados Unidos, e considerando a relação histórica entre Argentina e Chile, por questões também de proximidade fronteiriça, optámos por analisar, nesta dissertação, o papel da Argentina na mudança de regime no Chile. Não se trata apenas de compreender a influência argentina no processo, mas também analisar o impacto da própria democratização no país num processo semelhante no Chile. É, também, por este motivo que este estudo abarca um período temporal que se inicia em 1983 (democratização da Argentina) e termina em 1990 (ano em que o Chile muda de regime, deixando para trás o autoritarismo). Tendo por base o modelo de Levitsky & Way e os conceitos desenvolvidos por Whitehead & Schmitter, esta dissertação baseia-se num quadro analítico que parte do trabalho destes quatro autores. De Levitsky & Way, bebe duas noções-chave: o conceito de leverage (grau de vulnerabilidade de um país à influência externa) e linkage (densidade de laços transfronteiriços). De Whitehead & Schmitter recorre a três conceitos (contágio, consentimento e condicionalidade) que permitem caracterizar, de certo modo, o tipo de influência externa. Além da operacionalização do modelo, este trabalho inclui, também, um capítulo mais descritivo sobre a democratização chilena e os seus antecedentes e uma parte, também ela de cariz mais descritivo, dedicada à dimensão internacional do processo. Este estudo procura, assim, mostrar a importância do contexto internacional na democratização do Chile, alertando para a necessidade de não centrar o estudo das democratizações apenas em factores de ordem interna.
