¿Reemplazo demográfico en el Neolítico europeo? El punto de vista de la Genética

[ES] El trabajo realiza una aproximación a la situación actual de los estudios de ADN antiguo humano en Europa, recopilando los datos de los individuos analizados hasta 2013 (n=700), a modo de síntesis interpretativa continental y regional de los territorios para los cuales se han obtenido resultados significativos (Centroeuropa, Cornisa Cantábrica, Mediterráneo occidental, Escandinavia-Báltico-Rusia y Alpes orientales). Las hipótesis se expresan en términos de continuidad o discontinuidad genética entre los grupos humanos habitantes de un territorio, centradas en la problemática de la neolitización, en una horquilla cronocultural del Paleolítico superior a la Edad del Bronce. Los resultados se resumen en (1) una preponderancia del clado mitocondrial U para muestras preneolíticas; (2) la posibilidad de una intrusión démica en una fase inicial de la neolitización centroeuropea -tipo N1a, con pérdida posterior de ese haplogrupo mitocondrial-; (3) la evidencia del proceso neolitizador como heterogéneo y con diferente impacto a escala regional; (4) una estabilización del acervo genético europeo actual como resultado de eventos postneolíticos; y (5) las posibilidades analíticas de la genética aplicada a las poblaciones antiguas como un instrumento de gran interés, observándose la necesidad de realizar más analíticas con recorrido diacrónico.

Unveiling the factors shaping the distribution of widely distributed alpine vertebrates, using multi-scale ecological niche modelling of the bat Plecotus macrobullaris

Several alpine vertebrates share a distribution pattern that extends across the South-western Palearctic but is limited to the main mountain massifs. Although they are usually regarded as cold-adapted species, the range of many alpine vertebrates also includes relatively warm areas, suggesting that factors beyond climatic conditions may be driving their distribution. In this work we first recognize the species belonging to the mentioned biogeographic group and, based on the environmental niche analysis of Plecotus macrobullaris, we identify and characterize the environmental factors constraining their ranges. Distribution overlap analysis of 504 European vertebrates was done using the Sorensen Similarity Index, and we identified four birds and one mammal that share the distribution with P. macrobullaris. We generated 135 environmental niche models including different variable combinations and regularization values for P. macrobullaris at two different scales and resolutions. After selecting the best models, we observed that topographic variables outperformed climatic predictors, and the abruptness of the landscape showed better predictive ability than elevation. The best explanatory climatic variable was mean summer temperature, which showed that P. macrobullaris is able to cope with mean temperature ranges spanning up to 16 degrees C. The models showed that the distribution of P. macrobullaris is mainly shaped by topographic factors that provide rock-abundant and open-space habitats rather than climatic determinants, and that the species is not a cold-adapted, but rather a cold-tolerant eurithermic organism. P. macrobullaris shares its distribution pattern as well as several ecological features with five other alpine vertebrates, suggesting that the conclusions obtained from this study might be extensible to them. We concluded that rock-dwelling and open-space foraging vertebrates with broad temperature tolerance are the best candidates to show wide alpine distribution in the Western Palearctic.

Prismas do exílio : trajetória intelectual e modelagem do self em Anatol Rosenfeld e Otto maria Carpeaux

Esta tese tem por objetivo investigar as trajetórias intelectuais de Anatol Rosenfeld e Otto Maria Carpeaux. Exilados no Brasil durante a década de 30 do século passado, em função do avanço do nazifascismo na Europa, o alemão Rosenfeld e o austríaco Carpeaux souberam reinventar suas existências na nova terra, transformando-se em dois dos maiores críticos literários do país. Além de examinar os itinerários percorridos por ambos os autores, esta tese terá como foco analisar a relação entre exílio e atividade intelectual, promovendo uma reflexão a respeito do lugar das cidades de Berlim e Viena na construção do arcabouço espiritual de Rosenfeld e Carpeaux. Este estudo também tratará das suas primeiras produções em solo brasileiro, bem como da recepção que obtiveram de seus anfitriões, delineando, assim, os contornos de uma complexa atmosfera intelectual marcada por uma espécie de cordialidade literária. Como último objetivo, esta tese debaterá o processo de modelagem do self por meio do qual ambos os críticos conseguiram aprimorar a própria individualidade, tornando-se, enfim, figuras cuja memória deve ser recuperada.

Novos olhares sobre Viena: um estudo sobre o recente trabalho de reavaliação do positivismo lógico

A pesquisa que ora se apresenta consiste em uma investigação sobre o recente trabalho de reavaliação das obras de membros do chamado Círculo de Viena, que foi o primeiro e principal grupo representativo da perspectiva filosófica conhecida como positivismo lógico. Nossa pesquisa compreende três partes: a primeira parte voltada para a reconstrução histórico-conceitual do período entre o alvorecer das idéias neopositivistas e os primeiros momentos posteriores à recepção norte-americana da imigração intelectual vienense; na segunda parte do trabalho, por sua vez, lançaremos luz propriamente à natureza de tal perspectiva contemporânea, a partir de uma descrição sobre o método e o escopo temático de tal projeto revisionista; à terceira parte, por fim, além de tecer uma avaliação geral sobre o que foi feito nas duas partes que a antecedem, coube conjecturar as possibilidades de se encontrar em tal trabalho uma agenda filosófica e política própria.

A fábrica de peles: Hundertwasser e o caminhar contemporâneo

Por convergência teórica, esta tese de dissertação é estruturada em quatro capítulos, retomando a teoria das cinco peles de Hundertwaser. O artista austríaco, filho de mãe judia e pai ariano, realizou em Paris sua primeira exposição no ano de 1954 e desde então, não cessou mais de trabalhar, aglutinando os exercícios de arquiteto, ambientalista, naturista e higienista moral, assim como as atividades de pintor e gravador, todos efetivados nos múltiplos diálogos estabelecidos por cada pele. As cinco peles de Hundertwasser acredita o homem como um ser de camadas, que se desenrolam por uma espiral concêntrica, que parte do eu-profundo para o mundo exterior, operada por osmose, nas cadeias sucessivas dos níveis de consciência do indivíduo. as cinco peles de Hundertwasser são um plano de vida - e mais: uma reflexão profunda do ser e estar sobre a terra, colocado em prática ao longo de sua jornada artística. A abordagem pretende desdobrar tal teoria - o que cada pele me suscita - no corpo fabril da minha produção em relação a de outros artistas e teóricos. A transmissão das cinco peles de Hunderwasser desenvolve-se em situações de alargamento das peles. Uma apropriação que re contextualiza, revela novos posicionamentos no caminhar da arte contemporânea

Enhanced infrared emission from colloidal HgTe nanocrystal quantum dots on silicon-on-insulator photonic crystals

A two dimensional silicon-on-insulator based photonic crystal structure is used to enhance the emission from colloidal HgTe nanocrystal quantum dots embedded in a thin polymer film. The enhancement is resonant to the leaky eigenmodes of the photonic crystals due to coherent scattering effects. Transmittance and photoluminescence experiments are presented to map the leaky mode dispersion and the angle dependence of the emission enhancement factor, which reaches values up to 80 (650) for vertical (oblique) emission in the telecommunication wavelength range.

Extreme weathering/erosion during the Miocene Climatic Optimum: Evidence from sediment record in the South China Sea

Investigating the interplay between continental weathering and erosion, climate, and atmospheric CO2 concentrations is significant in understanding the mechanisms that force the Cenozoic global cooling and predicting the future climatic and environmental response to increasing temperature and CO2 levels. The Miocene represents an ideal test case as it encompasses two distinct extreme climate periods, the Miocene Climatic Optimum (MCO) with the warmest time since 35 Ma in Earth's history and the transition to the Late Cenozoic icehouse mode with the establishment of the east Antarctic ice sheet. However the precise role of continental weathering during this period of major climate change is poorly understood. Here we show changes in the rates of Miocene continental chemical weathering and physical erosion, which we tracked using the chemical index of alteration ( CIA) and mass accumulation rate ( MAR) respectively from Ocean Drilling Program (ODP) Site 1146 and 1148 in the South China Sea. We found significantly increased CIA values and terrigenous MARs during the MCO (ca. 17-15 Ma) compared to earlier and later periods suggests extreme continental weathering and erosion at that time. Similar high rates were revealed in the early-middle Miocene of Asia, the European Alps, and offshore Angola. This suggests that rapid sedimentation during the MCO was a global erosion event triggered by climate rather than regional tectonic activity. The close coherence of our records with high temperature, strong precipitation, increased burial of organic carbon and elevated atmospheric CO2 concentration during the MCO argues for long-term, close coupling between continental silicate weathering, erosion, climate and atmospheric CO2 during the Miocene.

Descriptions of Protospathidium serpens (Kahl, 1930) and P-fraterculum n. sp (Ciliophora, Haptoria), two species based on different resting cyst morphology

Protospathidium serpens (Kahl, 1930) is frequent in semiterrestrial and terrestrial habitats worldwide. Conventionally, all populations are considered as conspecific because they have very similar overall morphologies and morphometrics. We studied in detail not only the morphology of the vegetative cells but also the resting cysts using live observation, protargol impregnation, and scanning electron microscopy. These revealed a cryptic diversity and biogeographic pattern in details of the dorsal brush and cyst wall morphology. The cyst wall is spiny in the Austrian specimens, while smooth in the South African and Antarctic populations. Accordingly, P. serpens consists of at least two species: P. serpens (with spiny cyst wall) and P. fraterculum n. sp. (with smooth cyst wall); the latter is probably composed of two distinct taxa differing by the absence (South African)/presence (Antarctic) of a monokinetidal bristle tail in brush row 3, the number of dikinetids comprising brush row 1 (seven versus three), and the total number of brush dikinetids (29 versus 17). Protospathidium serpens is neotypitied with the new population from Austria. The significance of resting cyst morphology is discussed with respect to alpha-taxonomy and overall ciliate diversity.

Produkcja w spadkowej fazie cyklu koniunkturalnego w Polsce

Opracowanie ma charakter teoretyczno-empiryczny. Jego głównym celem jest weryfikacja dwóch zasadniczych dla austriackiej teorii cyklu koniunkturalnego hipotez. Pierwsza hipoteza mówi, że restrykcyjna polityka pieniężna powoduje skracanie struktury produkcji, druga ¬– że podwyżki stóp prowadzą do względnych różnic w spadku produkcji branż wytwarzających dobra w różnych odległościach od konsumenta. Przeprowadzona w opracowaniu analiza, oparta na przyjętych wskaźnikach, pozwala pozytywnie zweryfikować obie hipotezy. Podwyżki stóp procentowych dokonane przez Narodowy Bank Polski prowadziły do powstawania spadkowych faz cyklu. W tym okresie w polskiej gospodarce zmniejszał się czas produkcji dóbr finalnych oraz występowały względne różnice w spadkach produkcji w branżach oddalonych w różnym stopniu od ostatecznego odbiorcy.

Three Voices in the Wilderness: Foote, Bloch, and Korngold in the Early Twentieth-Century America

Barbara Hanning points out in her book Concise History of Western Music, that "Twentieth-century American music was in large measure an extension of European music" (Hanning 1998, 515). My dissertation/perforrnance project features cello works written by three contemporary composers who lived in America but were connected to the European heritage in different ways; each contributed significantly to the development of American classical concert life, music education, and even popular culture. Programs of my performances are intended to illustrate their unique compositional styles. The first recital consists of five cello compositions of Massachusetts-born Arthur Foote (1853 - 1937): Drei Stucke fur Pianoforte und Violoncello, Op. 1; Scherzo, Op.22; Romanza, Op.33; Aubade, Op.77; and Sonata for Violoncello and Piano, Op.78. Foote was influenced by the German-trained John Knowles Paine at Harvard University; he composed music famous for its extensive chromaticism in both harmony and melodic line, and for clearly-defined formal structure. The second recital explores the music of Swiss-American composer Ernest Bloch (1880-1959): a short Meditation Hebraique, a Suite No. I for Violoncello Solo and the famous rhapsody Schelomo. Born in Geneva, Switzerland, and settling in the United States in 1916, Bloch is a composer deeply influenced by the European late-Romantic tradition and is also well-known for employing "Hebraic" elements into his works. The final performance comprises two other of Bloch's cello works and one cello concerto by the Austrian-American composer, Erich Wolfgang Korngold (1897- 1957). Bloch's Voice in the Wilderness is a symphonic poem for orchestra and cello (accompanied by piano in this performance), consisting of six movements performed without pause. His Suite No.3 for Cello Solo is shorter and has a simpler style than the first Suite. Korngold was recognized as a child prodigy in his native Austria. After a Nazi-induced exile, he immigrated to America and became a film music composer in Hollywood. The Cello Concerto was used in the movie "Deception" (1 946), for which Korngold provided the film score. The impassioned harmonic language and lavish melodic lines inherited from the high-romanticism make this work one of comparative discordant beauty among other compositions of his time.
