Reducciones Jesuiticas en el Chaco, Noroeste y Sur Argentino. Emplazamiento Territorial. Desarrollo Urbano y Arquitectónico entre los siglos XVII y XVIII. Evolución, Funciones y Tipologías. Reductions in the Chaco, Argentine Northwest and South. Territorial emplazan. Architectural and Urban Development between the seventeenth and eighteenth centuries. Evolution, Functions and Typologies.

Las reducciones jesuíticas en Argentina reconocen generalmente un único aporte en la región guaraní. Pero lo cierto es que una cantidad importante de reducciones, equivalente en número con las anteriormente mencionadas, se desarrollaron en el interior del país, fundamentalmente en las regiones del Chaco, noroeste y sur argentino. Muchas de ellas reconocen hoy su continuidad en centros urbanos y otras tan sólo, y en el mejor de los casos, en vestigios arqueológicos. Se propone el análisis de este conjunto desde las primeras incursiones en "misiones volantes" en el siglo XVII hasta la expulsión de los jesuitas en 1767. También se abordarán las modalidades y procesos generadores de centros reduccionales en estas regiones y sus interrelaciones territoriales. Además se pretende analizar sus funciones y morfologías originales, su evolución, traslados y posibles transformaciones posteriores, en las etapas previas al impacto originado ante la ausencia de la Compañía de Jesús. Los resultados incluirán la interpretación de los procesos formativos, con su diversidad de casos, en escalas regionales y locales, la recopilación de cartografía regional y urbana, y la determinación de series tipológicas de formas de trazados y organizaciones de tejidos, tanto en las demarcaciones de origen como en sus remodelaciones y ensanches cuando así correspondiere.

Domesticación y conservación de plantas nativas del centro de Argentina con potencial de usos múltiples. Domestication and conservation of native plants from central Argentine with multiple potential uses.

Con el retroceso de los bosques nativos se pierden hábitats y recursos fitogenéticos. Existen investigaciones científicas, técnicas y rescate de saberes populares sobre el aprovechamiento de especies autóctonas, búsqueda de productos derivados y servicios ambientales. Entre ellos se destacan estudios locales sobre principios activos con actividad pesticida y medicinal y el uso en paisajismo, mejoramiento ambiental y remediación de paisajes degradados. La información para propagar muchas especies nativas cuyo uso se promueve, no existe o no está calibrada para escala de cultivos intensivos. Este proyecto se enfoca sobre cuatro especies endémicas o nativas de Espinal y Chaco, que tienen gran valor de conservación y son promisorias por su potencial simultáneo de aplicación paisajística y para elaboración de pesticidas. La meta es promover la conservación regional de flora nativa a través del uso, con estrategias in situex situ en áreas urbanas, industriales y rurales. Los objetivos específicos son a-Conservar y caracterizar muestras de las especies Flourensia oolepis, Dolichandra cynanchoides, Lepechinia floribunda y Achyrocline satureioides en el Banco Activo de Germoplasma del Jardín Botánico Gaspar Xuárez sj de la UCC; b-Estudiar la propagación y cultivo de dichas especies y c- Transferir información y capacitar recursos humanos en técnicas de cultivo intensivo ambientalmente sustentable. La metodología contempla: a- Recolección georreferenciada de germoplasma a campo, que se conservará acondicionado en el Banco; b- Caracterización y evaluación de calidad de semillas en laboratorio siguiendo normas internacionales ISTA (peso de mil semillas, poder germinativo y viabilidad) y c- Calibración de protocolos de propagación sexual y cultivo en vivero (variables de supervivencia, sustratos, inóculos). La capacitación de recursos humanos se hará mediante pasantías y talleres de capacitación en el marco del Jardín Botánico y transferencia de información a viveristas, emprendedores y paisajistas. Como productos se esperan 40 nuevas accesiones al Banco y su correspondiente evaluación de calidad de semillas, protocolos de métodos de propagación y cultivo, la realización de un taller de capacitación y una pasantía al año y la publicación de resultados. La pertinencia de estudiar la domesticación de estas especies surge frente a su potencial de uso para múltiples fines y frente al poco desarrollo que aún presenta el sector de producción intensiva de especies nativas. Se espera que la información generada sirva de base, tanto para aportar materias primas y avanzar regionalmente en el desarrollo agroindustrial de pesticidas naturales, como para la provisión de ejemplares cultivados con técnicas conservativas de variabilidad y viabilidad genética para intervenciones paisajistas en áreas urbanas y remediación de paisajes, evitando la extracción directa del recurso.

Iglesia argentina y memoria de las víctimas de la última dictadura militar. Revisión del discurso y de la praxis eclesial de reconciliación, a partir de determinados aportes de la Escuela de Frankfurt y de la Nueva Teología Política. Argentine Church and Memory of the Victims of the Military Dictatorship. Review of the Ecclesiastic Discourse and Praxis of Reconciliation.

En el marco de la recuperación de la memoria en relación con los hechos de la última dictadura militar es importante determinar los motivos ideológico-teológicos y prácticos que dificultaron una oposición significativa por parte de la jerarquía de la iglesia a la violación de los derechos humanos, e individualizar los argumentos que impulsaron un discurso y una praxis de reconciliación que privilegió el olvido de las víctimas y apoyó acríticamente los «proyectos de olvido», como la ley de punto final, entre otros. Para analizar dichos discursos y praxis se recurre principalmente a Johann Metz, quien, vinculado a la Escuela de Frankfurt, propone una razón anamnética del sufrimiento ajeno. La originalidad del proyecto es doble, por su contenido y por su enfoque: la confrontación del «servicio de reconciliación» eclesial con la «memoria de las víctimas». Hipótesis de trabajo: el discurso y la praxis eclesial en relación al «servicio de reconciliación» realizado por el Episcopado argentino a partir de 1981, pone de manifiesto: primero, que siguieron vinculados a la idea de "nación católica" (Zanatta 1996, Dri 1997, Esquivel 2004), lo que dificultó, junto a otros factores, la visibilización de las víctimas; segundo, a su vez, analizados a la luz de los aportes filosófico-teológicos mencionados, muestran una notable carencia en la valoración de la memoria de las víctimas, esperable en una reconciliación. Objetivo general: realizar un análisis crítico de los discursos y prácticas institucionales oficiales de la Iglesia católica en Argentina en relación con la memoria de las víctimas de la última dictadura militar. Objetivos específicos: confrontar las experiencias eclesiales argentinas recientes, y sus conceptualizaciones y tipos de argumentación, con una tradición de pensamiento que en relación al acontecimiento del Holocausto sitúa en el centro de la reflexión temas como el de la memoria, el sufrimiento de las víctimas, y un modo peculiar de tratamiento de los hechos históricos; además, individualizar y analizar los argumentos que dificultaron la búsqueda de la justicia y la memoria de las víctimas. Metodología y etapas. 1° Etapa: analizar y sistematizar algunos aspectos de las teorías del conocimiento histórico y de la razón comunicativa en determinadas obras de Benjamin, Bloch y Habermas; posteriormente, precisar la apropiación conceptual de las categorías histórico-filosóficas de dichas corrientes llevada a cabo por Metz para elaborar su «memoria de las víctimas». 2° Etapa: revisar el discurso y la praxis eclesial a partir de 1981 a la luz del marco teórico ya estudiado. Será necesario, por una parte, detenerse en las declaraciones eclesiales oficiales referidas al retorno de la democracia, a las leyes de punto final y obediencia debida, como así también, en el reconocimiento y pedido de perdón por las culpas del pasado.

Regímenes Internacionales y Derechos Humanos. La incidencia del sistema interamericano de protección en la legislación y jurisprudencia argentinas. International Regimes and Human Rights. The incidence of inter-American system in Argentine law and jurisprudence.

El nuevo escenario internacional produce lo que se ha dado en caracterizar como la globalización del derecho, especialmente en el ámbito de los derechos humanos. En este contexto se analiza la incidencia del Sistema Interamericano de protección de los Derechos Humanos con especial énfasis en el derecho de la información, desde la optica del derecho interno. Nos preguntamos acerca de cómo se presenta la tensión entre la lógica estatal con su rasgo de afirmación en la soberanía y monopolio en la creación de la jurisdicción doméstica, con la doctrina del derecho internacional de los derechos humanos, que consecuentemente conduce hacia una globalización jurídica de estos temas. Esto refleja un debilitamiento en el monopolio de creación y aplicación del derecho por parte de los Estados. A partir de este dato del escenario internacional buscamos determinar la incidencia de los informes de la Comisión Interamericana de Derechos Humanos y los pronunciamientos de la Corte Interamericana en materia de derecho de la información y su influencia en la jurisprudencia y creación de legislación en nuestro país. The new internacional scenario produces wtah has come to be characterized as the globalization of law, especially in the field of the human rights. In this context we analyze the impact of the Inter-American system of human Rights, whit particular emphasis on media law in domestic law

What value can be attached to a concept of mystery and has it a place in contemporary Western culture?

The idea for this thesis arose from a chain of reactions first set in motion by a particular experience. In keeping with the contemporary need to deconstruct every phenomenon it seemed important to analyse this experience in the hope of a satisfactory explanation. The experience referred to is the aesthetic experience provoked by works of art. The plan for the thesis involved trying to establish whether the aesthetic experience is unique and individual, or whether it is one that is experienced universally. Each question that arises in the course of this exploration promotes a dialectical reaction. I rely on the history of aesthetics as a philosophical discipline to supply the answers. This study concentrates on the efforts by philosophers and critical theorists to understand the tensions between the empirical and the emotional, the individual and the universal responses to the sociological, political and material conditions that prevail and are expressed through the medium of art. What I found is that the history of aesthetics is full of contradictory evidence and cannot provide a dogmatic solution to the questions posed. In fact what is indicated is that the mystery that attaches to the aesthetic experience is one that can also apply to the spiritual or transcendent experience. The aim of this thesis is to support the contribution of visual art in the spiritual well being of human development and supports the uniqueness of the evaluation and aesthetic judgement by the individual of a work of art. I suggest that mystery will continue to be of value in the holistic development of human beings and this mystery can be expressed through visual art. Furthermore, this thesis might suggest that what could be looked at is whether a work of art may be redemptive in its affect and offset the current decline in affective religious practice.

Estudos experimentais sôbre a origem do milho

1) It may seem rather strange that, in spite of the efforts of a considerable number of scientists, the problem of the origin of indian corn or maize still has remained an open question. There are no fossil remains or archaeological relics except those which are quite identical with types still existing. (Fig. 1). The main difficulty in finding the wild ancestor- which may still exist - results from the fact that it has been somewhat difficult to decide what it should be like and also where to look for it. 2) There is no need to discuss the literature since an excellent review has recently been published by MANGELSDORF and REEVES (1939). It may be sufficient to state that there are basically two hypotheses, that of ST. HILAIRE (1829) who considered Brazilian pod corn as the nearest relative of wild corn still existing, and that of ASCHERSON (1875) who considered Euchlaena from Central America as the wild ancestor of corn. Later hypotheses represent or variants of these two hypotheses or of other concepts, howewer generally with neither disproving their predecessors nor showing why the new hypotheses were better than the older ones. Since nearly all possible combinations of ideas have thus been put forward, it har- dly seems possible to find something theoretically new, while it is essential first to produce new facts. 3) The studies about the origin of maize received a new impulse from MANGELSDORF and REEVES'S experimental work on both Zea-Tripsacum and Zea-Euchlaena hybrids. Independently I started experiments in 1937 with the hope that new results might be obtained when using South American material. Having lost priority in some respects I decided to withold publication untill now, when I can put forward more concise ideas about the origin of maize, based on a new experimental reconstruction of the "wild type". 4) The two main aspects of MANGELSDORF and REEVES hypothesis are discussed. We agree with the authors that ST. HILAIRE's theory is probably correct in so far as the tunicata gene is a wild type relic gene, but cannot accept the reconstruction of wild corn as a homozygous pod corn with a hermaphroditic tassel. As shown experimentally (Fig. 2-3) these tassels have their central spike transformed into a terminal, many rowed ear with a flexible rachis, while possessing at the same time the lateral ear. Thus no explanation is given of the origin of the corn ear, which is the main feature of cultivated corn (BRIEGER, 1943). The second part of the hypothesis referring to the origin of Euchlaena from corn, inverting thus ASCHERSON's theory, cannot be accepted for several reasons, stated in some detail. The data at hand justify only the conclusion that both genera, Euchlaena and Zea, are related, and there is as little proof for considering the former as ancestor of the latter as there is for the new inverse theory. 5) The analysis of indigenous corn, which will be published in detail by BRIEGER and CUTLER, showed several very primitive characters, but no type was found which was in all characters sufficiently primitive. A genetical analysis of Paulista Pod Corn showed that it contains the same gene as other tunicates, in the IV chromosome, the segregation being complicated by a new gametophyte factor Ga3. The full results of this analysis shall be published elsewhere. (BRIEGER). Selection experiments with Paulista Pod Corn showed that no approximation to a wild ancestor may be obtained when limiting the studies to pure corn. Thus it seemed necessary to substitute "domesticated" by "wild type" modifiers, and the only means for achieving this substitution are hybridizations with Euchlaena. These hybrids have now been analysed init fourth generation, including backcrosses, and, again, the full data will be published elsewhere, by BRIEGER and ADDISON. In one present publication three forms obtained will be described only, which represent an approximation to wild type corn. 6) Before entering howewer into detail, some arguments against ST. HILAIRE's theory must be mentioned. The premendelian argument, referring to the instability of this character, is explained by the fact that all fertile pod corn plants are heterozygous for the dominant Tu factor. But the sterility of the homozygous TuTu, which phenotypically cannot be identified, is still unexplained. The most important argument against the acceptance of the Tunicata faetor as wild type relic gene was removed recently by CUTLER (not yet published) who showed that this type has been preserved for centuries by the Bolivian indians as a mystical "medicine". 7) The main botanical requirements for transforming the corn ear into a wild type structure are stated, and alternative solutions given. One series of these characters are found in Tripsacum and Euchlaena : 2 rows on opposite sides of the rachis, protection of the grains by scales, fragility of the rachis. There remains the other alternative : 4 rows, possibly forming double rows of female and male spikelets, protection of kernels by their glumes, separation of grains at their base from the cob which is thin and flexible. 8) Three successive stages in the reconstruction of wild corn, obtained experimentally, are discussed and illustrated, all characterized by the presence of the Tu gene. a) The structure of the Fl hybrids has already been described in 1943. The main features of the Tunicata hybrids (Fig. -8), when compared with non-tunicate hybrids (Fig. 5-6), consist in the absence of scaly protections, the fragility of the rachis and finally the differentiation of the double rows into one male and one female spikelet. As has been pointed out, these characters represent new phenotypic effects of the tunicate factor which do not appear in the presence of pure maize modifiers. b) The next step was observed among the first backcross to teosinte (Fig. 9). As shown in the photography, Fig. 9D, the features are essencially those of the Fl plants, except that the rachis is more teosinte like, with longer internodes, irregular four-row-arrangement and a complete fragility on the nodes. c) In the next generation a completely new type appeared (Fig. 10) which resembles neither corn nor teosinte, mainly in consequence of one character: the rachis is thin and flexible and not fragile, while the grains have an abscission layer at the base, The medium sized, pointed, brownish and hard granis are protected by their well developed corneous glumes. This last form may not yet be the nearest approach to a wild grass, and I shall try in further experiments to introduce other changes such as an increase of fertile flowers per spikelet, the reduction of difference between terminal and lateral inflorescences, etc.. But the nature of the atavistic reversion is alveadwy such that it alters considerably our expectation when looking for a still existing wild ancestor of corn. 9) The next step in our deductions must now consist in an reversion of our question. We must now explain how we may obtain domesticated corn, starting from a hypothetical wild plant, similar to type c. Of the several changes which must have been necessary to attract the attention of the Indians, the following two seem to me the most important: the disappearance of all abscission layers and the reduction of the glumes. This may have been brought about by an accumulation of mutations. But it seems much more probable to assume that some crossing with a tripsacoid grass or even with Tripsacum australe may have been responsible. In such a cross, the two types of abscission layer would be counterbalanced as shown by the Flhybrids of corn, Tripsacum and Euchlaena. Furthermore in later generations a.tu-allele of Tripsacum may become homozygous and substitute the wild tunicate factor of corn. The hypothesis of a hybrid origin of cultivated corn is not completely new, but has been discussed already by HARSHBERGER and COLLINS. Our hypothesis differs from that of MANGELSDORF and REEVES who assume that crosses with Tripsacum are responsible only for some features of Central and North American corn. 10) The following arguments give indirects evidence in support of our hypothesis: a) Several characters have been observed in indigenous corn from the central region of South America, which may be interpreted as "tripsacoid". b) Equally "zeoid" characters seem to be present in Tripsacum australe of central South-America. c) A system of unbalanced factors, combined by the in-tergeneric cross, may be responsible for the sterility of the wild type tunicata factor when homozygous, a result of the action of modifiers, brought in from Tripsacum together with the tuallele. d) The hybrid theory may explain satisfactorily the presence of so many lethals and semilethals, responsible for the phenomenon of inbreeding in cultivated corn. It must be emphasized that corn does not possess any efficient mechanism to prevent crossing and which could explain the accumulation of these mutants during the evolutionary process. Teosinte which'has about the same mechanism of sexual reproduction has not accumulated such genes, nor self-sterile plants in spite of their pronounced preference for crossing. 11) The second most important step in domestication must have consisted in transforming a four rowed ear into an ear with many rows. The fusion theory, recently revived byLANGHAM is rejected. What happened evidently, just as in succulent pXants (Cactus) or in cones os Gymnosperms, is that there has been a change in phyllotaxy and a symmetry of longitudinal rows superimposed on the original spiral arrangement. 12) The geographical distribution of indigenous corn in South America has been discussed. So far, we may distinguish three zones. The most primitive corn appears in the central lowlands of what I call the Central Triangle of South America: east of the Andies, south of the Amazone-Basin, Northwest of a line formed by the rivers São Prancisco-Paraná and including the Paraguay-Basin. The uniformity of the types found in this extremely large zone is astonishing (BRIEGER and CUTLER). To the west, there is the well known Andian region, characterized by a large number of extremely diverse types from small pop corn to large Cuszco, from soft starch to modified sweet corn, from large cylindrical ears to small round ears, etc.. The third region extends along the atlantic coast in the east, from the Caribean Sea to the Argentine, and is characterized by Cateto, an orange hard flint corn. The Andean types must have been obtained very early, and undoubtedly are the result of the intense Inca agriculture. The Cateto type may be obtained easily by crosses, for instance, of "São Paulo Pointed Pop" to some orange soft corn of the central region. The relation of these three South American zones to Central and North America are not discussed, and it seems essential first to study the intermediate region of Ecuador, Colombia and Venezuela. The geograprical distribution of chromosome knobs is rapidly discussed; but it seems that no conclusions can be drawn before a large number of Tripsacum species has been analysed.

Comparison of Contemporary Protocols for High-speed Data Transport via 10 Gbps WAN Connections

This work is dedicated to comparison of open source as well as proprietary transport protocols for highspeed data transmission via IP networks. The contemporary common TCP needs significant improvement since it was developed as general-purpose transport protocol and firstly introduced four decades ago. In nowadays networks, TCP fits not all communication needs that society has. Caused of it another transport protocols have been developed and successfully used for e.g. Big Data movement. In scope of this research the following protocols have been investigated for its efficiency on 10Gbps links: UDT, RBUDP, MTP and RWTP. The protocols were tested under different impairments such as Round Trip Time up to 400 ms and packet losses up to 2%. Investigated parameters are the data rate under different conditions of the network, the CPU load by sender andreceiver during the experiments, size of feedback data, CPU usage per Gbps and the amount of feedback data per GiByte of effectively transmitted data. The best performance and fair resources consumption was observed by RWTP. From the opensource projects, the best behavior is showed by RBUDP.
