Invariance of brain-wave representations of simple visual images and their names

In two experiments, electric brain waves of 14 subjects were recorded under several different conditions to study the invariance of brain-wave representations of simple patches of colors and simple visual shapes and their names, the words blue, circle, etc. As in our earlier work, the analysis consisted of averaging over trials to create prototypes and test samples, to both of which Fourier transforms were applied, followed by filtering and an inverse transformation to the time domain. A least-squares criterion of fit between prototypes and test samples was used for classification. The most significant results were these. By averaging over different subjects, as well as trials, we created prototypes from brain waves evoked by simple visual images and test samples from brain waves evoked by auditory or visual words naming the visual images. We correctly recognized from 60% to 75% of the test-sample brain waves. The general conclusion is that simple shapes such as circles and single-color displays generate brain waves surprisingly similar to those generated by their verbal names. These results, taken together with extensive psychological studies of auditory and visual memory, strongly support the solution proposed for visual shapes, by Bishop Berkeley and David Hume in the 18th century, to the long-standing problem of how the mind represents simple abstract ideas.

Erasmus Darwin e os seres vivos: concepções de \'evolução\' e herança

Erasmus Darwin (1731-1802) apresentou suas ideias evolutivas principalmente no fim do século XVIII. No entanto, elas não foram consideradas na época. Seu neto, Charles Darwin (1809-1882), na 6ª edição do Origin of species as avaliou de modo negativo, comparando-as às concepções equivocadas de Lamarck. O objetivo desta dissertação é inicialmente, descrever as concepções de hereditariedade e evolução de Erasmus, considerando o contexto de sua época. Além disso, procura esclarecer se o tratamento recebido se deveu a uma proposta fraca ou se ela mereceria uma maior consideração. Esta dissertação contém uma Introdução e quatro capítulos. O Capítulo 1 discute a vida, trabalhos e contexto em que Erasmus apresentou suas ideias. O Capítulo 2 lida com as concepções de herança e evolução presentes em Zoonomia. O Capítulo 3 discute sobre as concepções de Erasmus sobre a transformação das espécies nas plantas. O Capítulo 4 compara as concepções evolutivas de Erasmus com as de Lamarck. O Capítulo 5 procura responder às perguntas colocadas no início desta pesquisa e apresenta algumas considerações finais sobre o assunto discutido. Esta pesquisa leva à conclusão de que a transmutação das espécies não era o principal interesse de Erasmus. Ele não ofereceu uma fundamentação empírica para suas ideias. Este fato, juntamente com a situação sócio-político-religiosa da época, muito provavelmente contribuiu para a recepção sofrida. Além disso, embora existam algumas semelhanças entre as propostas de Erasmus e Lamarck, existem também grandes diferenças tais como a abrangência da pesquisa, o espaço dedicado à discussão das ideias, a fundamentação oferecida, dentre outras. Erasmus não propôs uma teoria coerente lidando com desde a origem da vida até o aparecimento do homem como Lamarck. Ele somente apresentou algumas ideias a esse respeito em obras dedicadas a outros assuntos.

The American portrait tradition : Cephas Thompson 1775-1856

"The purpose of this study is to reveal the work of Cephas Thompson in the context of the American Portrait Tradition as it existed in America from 1775 to 1856. European historic and artistic background serves as the foundation. A critical analysis of the most relevant American portraitists from the seventeenth to the midnineteenth centuries is provided to relate them aesthetically and ideologically with the work of Cephas Thompson and to provide insight into the artistic trends prevalent in Europe and America"

El papel del clero en la expulsión de los jesuitas decretada por Carlos III en 1767

El presente trabajo trata sobre la reacción del clero secular y regular ante la expulsión de los jesuitas de la monarquía hispánica en 1767. Veremos las opiniones de algunos de los obispos favorables a la política regalista de Carlos III, y cómo actuaron antes la operación mejor diseñada y más eficaz contra la Compañía de Jesús en los amplios territorios del monarca Borbón. Al mismo tiempo, analizaremos los comentarios de los propios expulsos sobre el clero español y las consecuencias que tuvieron ambas reacciones.

Restoration of religious temples: intervention in the church “Nuestra Señora de Belén” in Crevillente (Alicante)

Heritage conservation has raised historical problems usually centered in defects resulting from water leaks. Thus, any intervention is presented as a difficult task, both due to building techniques to be used and the lack of economic resources in many cases. In relation to the temples existing in Alicante (Spain), water drainage is solved with pitched roofs on slope formation (in vaulted naves) or directly supported on the vaulted elements (in the domes). Since those construction systems are composed by brick and plaster, the presence of moisture is problematic, and represents a risk of losing the strength capacity and therefore the stability of the dome. An example of this problem is the dome of the church “Nuestra Señora de Belén” in Crevillente, built with solid bricks, it has the highest diameter of the province (18th century). This historic building has been restored on several occasions in the recent years due to moisture, cracks or fissures. The study of these works give an idea of the difficulties of maintenance, conservation and proper restoration of such kind of buildings as unique and valued constructions in our heritage.
