De l’expressió de la percepció sensorial auditiva a l’expressió del discurs reportat. El verb sentir en català medieval (s. XIII–XVI)

This study analyzes the process of semantic change by which the Old Catalan verb sentir developed from a meaning based on general perception to one implying auditory perception. In particular, the article shows that by the end of the 13th century the verb sentir had only semanticized the perception of non-linguistic auditory stimuli and had not fused completely with the meaning of the verb oir, as was the case with the evolution of SĔNTĪRE in other Romance languages (such as Peninsular Spanish). Our study has been based on data analysis of an electronic linguistic corpus using the concepts of E. C. Traugott’s Invited Inferencing Theory of Semantic Change (IITSC) (2012) and the concept of evidentiality.

As teorias da visão no Ocidente medieval até ao século XII: o comentário de Calcídio ao Timeu de Platão e a obra de Adelardo de Bath

A tradução do Timeu de Platão por Calcídio e respectivo Comentário, no século IV, encetou uma longa tradição no estudo da óptica durante a Idade Média, tradição esta que irá dominar até ao século XIII. O século XII, no entanto, irá ser marcado por um novo olhar neste campo, situação a que não é alheia a influência árabe que, pela mão de tradutores cristãos do ocidente, trouxe novas aportações científicas que vieram a contribuir para o desenvolvimento das correntes filosóficas sobre a matéria. Um desses tradutores foi Adelardo de Bath que, em pleno século XII, quer traduzindo obras árabes até aí desconhecidas do ocidente cristão, quer através da sua produção própria, lavrará o terreno adequado para o advento das sucessivas revoluções que a partir do século XIII surgiram neste campo.

O imaginário das ilhas atlânticas no universo medieval islâmico-cristão

O pensamento cultural medieval aparece-nos como herdeiro da Antiguidade Clássica, da sua filosofia, ciência, arte e mitos. Todos estes conceitos traduzem-se com facilidade para as elites intelectuais cristãs e muçulmanas, que os conservam e integram em elementos da sua própria cultura. A ideia do mar, em especial o mar dito ‘aberto’ como o Oceano Atlântico, é marcada pelo maravilhoso. Em plena Idade Média o Oceano Atlântico surge como território de Caos, envolto em mistério. O Oceano Atlântico é local das mais variadas manifestações do fantástico. Desta forma, as ilhas atlânticas, contidas neste vasto oceano, são elas próprias impregnadas de um carácter maravilhoso. Tentaremos, ao longo desta dissertação de mestrado, abordar a questão das ilhas atlânticas e das suas características a nível de imaginário. Este exercício será feito, sempre que possível, fazendo o cruzamento de fontes de origem islâmica e de origem cristã. Desta maneira, surgirá uma imagem comum em relação ao imaginário do Oceano Atlântico e, em especial, das ilhas neste contidas. O objetivo principal deste trabalho é verdadeiramente demonstrar pontos de aproximação entre relatos e mapas, de origem cristã e islâmica, ligados a ilhas fantásticas e, ao mesmo tempo, reais. Veremos que as duas categorias, do real e do imaginário, sobrepõem-se diversas vezes, sendo que não se conseguem muitas vezes distinguir a nível das fontes. Desta forma, relatos de navegações atlânticas como a de São Brandão (de origem celto-cristã) ou a dos Aventureiros de Lisboa (originária no al-Andalus,) são reveladoras das atitudes e ideias na Idade Média em relação ao Atlântico e às suas ilhas.

Unconfirmed but still feared: the tidal wave of Bulgarians and Romanians one year later. EPC Commentary, 15 January 2015

This time last year politicians and media were stoking fears over the massive floods of Romanians and Bulgarians who were about to invade the UK (but not only) as the employment restrictions for these EU citizens were being lifted in nine remaining EU Member States. These fears have proven to be unfounded. Nevertheless, major national and EU developments will continue to feed this debate.

(Table 1) Age determination of sediment core SO147_106KL

Here we present a high-resolution marine sediment record from the El Niño region off the coast of Peru spanning the last 20,000 years. Sea surface temperature, photosynthetic pigments, and a lithic proxy for El Niño flood events on the continent are used as paleo-El Niño-Southern Oscillation proxy data. The onset of stronger El Niño activity in Peru started around 17,000 calibrated years before the present, which is later than modeling experiments show but contemporaneous with the Heinrich event 1. Maximum El Niño activity occurred during the early and late Holocene, especially during the second and third millennium B.P. The recurrence period of very strong El Niño events is 60-80 years. El Niño events were weak before and during the beginning of the Younger Dryas, during the middle of the Holocene, and during medieval times. The strength of El Niño flood events during the last millennium has positive and negative relationships to global and Northern Hemisphere temperature reconstructions.

Mid-to Late Holocene flood frequency in the northeastern Alps as recorded in varved sediments of Lake Mondsee

Annually laminated (varved) lake sediments with intercalated detrital layers resulting from sedimentary input by runoff events are ideal archives to establish precisely dated records of past extreme runoff events. In this study, the mid- to late Holocene varved sediments of Lake Mondsee (Upper Austria) were analysed by combining sedimentological, geophysical and geochemical methods. This approach allows to distinguish two types of detrital layers related to different types of extreme runoff events (floods and debris flows) and to detect changes in flood activity during the last 7100 years. In total, 271 flood and 47 debris flow layers, deposited during spring and summer, were identified, which cluster in 18 main flood episodes (FE 1-18) with durations of 30-50 years each. These main flood periods occurred during the Late Neolithic (7100-7050 vyr BP and 6470-4450 vyr BP), the late Bronze Age and the early Iron Age (3300-3250 and 2800-2750 vyr BP), the late Iron Age (2050-2000 vyr BP), throughout the Dark Ages Cold Period (1500-1200 vyr BP), and at the end of the Medieval Warm Period and the Little Ice Age (810-430 vyr BP). Summer flood episodes in Lake Mondsee are generally more abundant during the last 1500 years, often coinciding with major advances of alpine glaciers. Prior to 1500 vyr BP, spring/summer floods and debris flows are generally less frequent, indicating a lower number of intense rainfall events that triggered erosion. In comparison with the increase of late Holocene flood activity in western and northwestern (NW) Europe, commencing already as early as 2800 yr BP, the hydro-meteorological shift in the Lake Mondsee region occurred much later. These time lags in the onset of increased hydrological activity might be either due to regional differences in atmospheric circulation pattern or to the sensitivity of the individual flood archives. The Lake Mondsee sediments represent the first precisely dated and several millennia long summer flood record for the northeastern (NE) Alps, a key region at the climatic boundary of Atlantic, Mediterranean and East European air masses aiding a better understanding of regional and seasonal peculiarities of flood occurrence under changing climate conditions.
