Ler e usar a literatura: alguns artifícios para o envolvimento do leitor

Nesta dissertação investigamos como a ficção envolve o leitor. Para isso, partimos da rejeição a Homero declarada por Calímaco, observando que a suposta diferença entre a literatura preferida pelo público e a literatura preferida pela crítica depende de dois fatores distintos. O primeiro é o simples fato de a crítica ler profissionalmente e o público ler por prazer. O segundo está relacionado à distinção entre recepção e uso da literatura proposta por C.S. Lewis. Na recepção, a obra tende a ser admirada por si; no uso, tende a ser instrumentalizada como suporte para um devaneio em que os desejos do próprio leitor são vicariamente satisfeitos. Observamos que essa devaneio, que Lewis chama de construção egoísta de castelos, e que inclui uma variante mórbida, tem um paralelo na noção girardiana do duplo angélico. Contudo, o devaneio depende da simpatia como definida por Adam Smith, a qual por sua vez depende de certa aprovação moral. Investigamos portanto o tipo de personagem que conquista a aprovação moral do leitor, contrastando os heróis homéricos com os cavaleiros cristãos a fim de verificar como o cristianismo dirige a aprovação moral para as vítimas, fazendo com que os heróis da ficção sejam pessoas perseguidas ou marginalizadas.

Historical evidence of abrupt coastal climatic change in Southern California, 1790-1880

Historical sources of the late-18th and 19th centuries were searched for information on coastal weather conditions in Southern California. Relatively calm winters until 1828 were followed by unusually stormy winters from about 1829 to 1839. Later periods were again predominantly calm, with notable exceptions related to the ENSO events of 1845 and 1878. Following decreases through the stormy 1830s, sizes of kelp forests appear to have rebounded in the 1840s. ENSO occurrences and eruption of the volcano Cosiguina in 1835 are likely causes for changing wind patterns. Our results link the unique AD 1840 Macoma leptonoidea pelecypod shell layer in laminated Santa Barbara Basin sediment ("Macoma event") to abruptly changing oceanographic and weather patterns.

Analysis of multivariable Smith predictors using MATLAB Containers

Containers are structured m-files which allow `data' and `methods' to be stored persistently. Containers have a user-defined class structure, so that one can have several Containers of the same class, all structurally similar, and there is a mechanism for interaction with Containers in the style of database transactions. The use of MATLAB Containers to analyze multivariable Smith predictors is discussed.

Vespid chemotactic peptide precursor from the wasp, Vespa magnifica (Smith)

Despite the evolutional distance between wasp and amphibian, vespid chemotactic peptide (VCP), an important component of wasp venom, are found sharing remarkable similarities with the temporin antimicrobial peptides (AMPs) from Ranid frog, Amolops loloens

A phospholipase A1 platelet activator from the wasp venom of Vespa magnifica (Smith)

Wasp is an impor tant venomous animal that can induce human fatalities. Aortic thrombosis and cerebral infarction are major clinical symptoms after massive wasp stings but the reason leading to the envenomation manifestation is still not known. In this paper, a toxin protein is purified and characterized by Sephadex G-75 gel filtration, CM-Sephadex C-25 cationic exchange and fast protein liquid chromatography (FPLC) from the venom of the wasp, Vespa magnifica (Smith). This protein, named magnifin, contains phospholipase-like activity and induces platelet aggregation. The cDNA encoding magnifin is cloned from the venom sac cDNA library of the wasp. The predicted protein was deduced from the cDNA with a sequence composed of 337 amino acid residues. Magnifin is very similar to other phospholipase A(1) (PLA(1)), especially to other wasp allergen PLA(1). Magnifin can activate platelet aggregation and induce thrombosis in vivo. The current results proved that PLA(1) in wasp venom could be contributable to aortic thrombosis after massive wasp stings. (c) 2007 Elsevier Ltd. All rights reserved.

On the little known species of threadfin breams Nemipterus mesoprion (Bleeker) and Nemipterus delagoae (Smith)

Among the fish species of the family Nemipteridae, the two little known species, namely, Nemipterus mesoprion (Bleeker) and Nemipterus delagoae (Smith) are recorded from the Cochin waters. Nemipterus mesoprion is a new distributional record from the west coast of India. N. delagoae is described with adequate numbers of specimen for the first time from Indian waters. Moreover, the results of the present study show that the colour of the viscera, the number of pyloric caeca and the gill rakers can also be used for the diagnosis of the species of the genus Nemipterus. The affinity of the above species with other related species of the genus Nemipterus and their geographical distribution are presented.

Two new species of the sisorid genus Oreoglanis Smith from Yunnan, China (Teleostei : Sisoridae)

Two new species of the genus Oreoglanis, O. jingdongensis and O. immaculatus are described from the Mekong and Salween River basins, respectively, of Yunnan Province, China. Oreoglanis jingdongensis can be distinguished from other Oreoglanis species by th
