Temporal interval production and short-term memory

Interference with time estimation from concurrent nontemporal processing has been shown to depend on the short-term memory requirements of the concurrent task (Fortin Breton, 1995; Fortin, Rousseau, Bourque, & Kirouac, 1993). In particular, it has been claimed that active processing of information in short-term memory produces interference, whereas simply maintaining information does not. Here, four experiments are reported in which subjects were trained to produce a 2,500-msec interval and then perform concurrent memory tasks. Interference with timing was demonstrated for concurrent memory tasks involving only maintenance. In one experiment, increasing set size in a pitch memory task systematically lengthened temporal production. Two further experiments suggested that this was due to a specific interaction between the short-term memory requirements of the pitch task and those of temporal production. In the final experiment, subjects performed temporal production while concurrently remembering the durations of a set of tones. Interference with interval production was comparable to that produced by the pitch memory task. Results are discussed in terms of a pacemaker-counter model of temporal processing, in which the counter component is supported by short-term memory.

Natural effusions: Mrs J. Howorth’s English translation of Albrecht von Haller’s Die Alpen

Albrecht von Haller's Die Alpen [The Alps] was an immensely popular piece of early eighteenth-century poetry, yet it took more than half a century to be translated into English. In this article I examine Mrs J. Howorth's prose rendering of it in her translated collection The Poems of Baron Haller (1794) and analyse how the translation itself reflects late-eighteenth-century scientific, political and aesthetic concerns, notably through the influence of Linnaeus and Jean-Jacques Rousseau. Secondly, I explore how Howorth constructed a public image of herself as a female consumer and producer of botanical literature, and argue that her translation constitutes an early example of British women's increasing engagement in science through the activity of translation.

Dietary factors impact on the association between CTSS variants and obesity related traits

BACKGROUND/AIMS: Cathepsin S, a protein coded by the CTSS gene, is implicated in adipose tissue biology--this protein enhances adipose tissue development. Our hypothesis is that common variants in CTSS play a role in body weight regulation and in the development of obesity and that these effects are influenced by dietary factors--increased by high protein, glycemic index and energy diets. METHODS: Four tag SNPs (rs7511673, rs11576175, rs10888390 and rs1136774) were selected to capture all common variation in the CTSS region. Association between these four SNPs and several adiposity measurements (BMI, waist circumference, waist for given BMI and being a weight gainer-experiencing the greatest degree of unexplained annual weight gain during follow-up or not) given, where applicable, both as baseline values and gain during the study period (6-8 years) were tested in 11,091 European individuals (linear or logistic regression models). We also examined the interaction between the CTSS variants and dietary factors--energy density, protein content (in grams or in % of total energy intake) and glycemic index--on these four adiposity phenotypes. RESULTS: We found several associations between CTSS polymorphisms and anthropometric traits including baseline BMI (rs11576175 (SNP N°2), p = 0.02, β = -0.2446), and waist change over time (rs7511673 (SNP N°1), p = 0.01, β = -0.0433 and rs10888390 (SNP N°3), p = 0.04, β = -0.0342). In interaction with the percentage of proteins contained in the diet, rs11576175 (SNP N°2) was also associated with the risk of being a weight gainer (p(interaction) = 0.01, OR = 1.0526)--the risk of being a weight gainer increased with the percentage of proteins contained in the diet. CONCLUSION: CTSS variants seem to be nominally associated to obesity related traits and this association may be modified by dietary protein intake.

CLUSTER MODEL FOR REACTIONS INDUCED BY WEAKLY BOUND AND/OR EXOTIC HALO NUCLEI WITH MEDIUM-MASS TARGETS

An experimental overview of reactions induced by the stable, but weakly-bound nuclei (6)Li, (7)Li and (9)Be, and by the exotic, halo nuclei (6)He, (8)B, (11)Be and (17)F On medium-mass targets, such as (58)Ni, (59)Co or (64)Zn, is presented. Existing data on elastic scattering, total reaction cross sections, fusion, breakup and transfer channels are discussed in the framework of a CDCC approach taking into account the breakup degree of freedom.

Women of Substance : The Aspect of Education, Career and Female Identity in Pride and Prejudice and Bridget Jones's Diary

Although two hundred years separate Jane Austen and Helen Fielding and, subsequently, also their portrayals of society, the similarities outweigh the differences. When juxtaposing Pride and Prejudice and Bridget Jones’s Diary in the light of feminism it is evident that both books provide clear examples of the prevailing situation of women in each time and place. The aspects of the study, which are especially important today, show both the development and some degree of stagnation of women’s rights and identities.

Vilhelm Ekelund och den fransk-italienska kultursfären : Några nedslag i de tidiga prosaverken - från Antikt ideal (1909) till Attiskt i fågelperspektiv (1919)

Vilhelm Ekelund och den fransk-italienska kultursfären: Några nedslag i de tidiga prosaverken – från Antikt ideal (1909) till Attiskt i fågelperspektiv (1919). (Vilhelm Ekelund and the French and Italian cultural heritage: A study of his early prose – from Antikt ideal (1909) to Attiskt i fågelperspektiv (1919)). The Swedish poet, essayist and aphorist Vilhelm Ekelund was not only influenced by German literature and philosophy, he also wrote extensive literary criticism on the subject of Romance language authors. This article discusses Ekelund’s relationship to some of the most influential French and Italian writers – as it can be seen in his work during the period 1909-1919. This relationship was ambiguous: he paid homage to French authors such as Montaigne, Montesquieu, Stendhal and Comte – as well as to the Italian poet and philosopher Leopardi – but he also severely criticized such distinguished writers as Baudelaire, Rousseau and Maupassant. One conclusion of this article is that the authors praised by Ekelund all venerate the Greek and Roman cultural heritage, whereas the despised novelists and poets were, in his opinion, either too “modern” or too “feminine” – both highly pejorative adjectives in the author’s terminology. It is also noted that Ekelund’s most ferocious attacks date from the first part of the decade, before he entered a more harmonic period with the works Metron (1918) and Attiskt i fågelperspektiv (1919).

O Brasil visto verticalmente : uma constelação chamada Monteiro Lobato

Abordamos, nesta tese, quatro perfis do escritor paulista Monteiro Lobato (1882-1948). Primeiro, seu lado visionário, que redundou na criação de uma extensa obra voltada para a infância e, paralelamente, em uma grande investida no mundo empresarial. É a utopia escrita e passada ao ato. Para levar a cabo seu trabalho hercúleo, Lobato sorveu da filosofia de Nietzsche o quantum satis para lhe redobrar a ímpeto intelectual. Este é o segundo ponto discutido aqui. Fazendo tabula rasa dos ideais educacionais de seu tempo, Lobato criou personagens paradigmáticos para povoar sua Utopia, calcados no pensamento de Rousseau (Emílio x Emília) e nos ideais do Iluminismo. É a matéria do terceiro capítulo. Para fechar o círculo, no quarto capítulo, examinamos os vínculos do autor com a sociedade norte-americana do início do século XX, que lhe forneceu o modelo de uma comunidade próspera e feliz, que o escritor sonhava implantar no Brasil.

Mídia, racionalidade e formação : uma abordagem filosófica

Esta pesquisa busca compreender o potencial de influência da mídia no processo formativo do ser humano na sociedade contemporânea. A abordagem é filosófica e, por isso, o enfoque priorizado na análise é o estudo da racionalidade nos diferentes períodos analisados. O ponto de partida foi buscar em Platão e Aristóteles a compreensão de Paidéia, pela qual se da a formação humana e do cidadão. Assim, mesmo acontecendo uma distinção entre as esferas pública e privada, a idéia formativa é extensiva aos dois âmbitos, principalmente a pública. No pensamento moderno, especialmente em Rousseau e Kant, a intenção é formar um homem virtuoso que seja ético para a sociedade. A vivência de sua cidadania funda-se em princípios racionais que, assim, exigem o exercício de posturas públicas e coletivas. Na contemporaneidade, a partir de Adorno e Horkheimer, a mídia é o novo elemento de forte influência no processo formativo das pessoas. Assim, racionalidade e mídia passam a se inter-relacionar simbioticamente e, por isso, necessitam ser analisados conjuntamente. Tal simbiose foi avaliada como sendo negativa para o esclarecimento do homem, tanto que a denúncia de Adorno e Horkheimer na Dialética do Esclarecimento apontou de que a racionalidade que sustenta a mídia é a mesma que restringe a ação do ser humano na sociedade. Nesse sentido, a racionalidade transforma-se num instrumento que serve ao interesse do mercado econômico, levando, o homem à barbárie ao invés de conduzi-lo a um estado de humanidade. Habermas avança na reflexão sobre a racionalidade, abandona a filosofia centrada no sujeito e desenvolve uma racionalidade comunicativa, a partir de uma filosofia da linguagem. O caráter discursivo dado à razão clarifica a influência da mídia na medida em que ele desenvolve, na sua teoria, as diferentes formas da racionalidade acontecer na sociedade contemporânea: a estratégica, normativa, dramatúrgica e a comunicativa que leva ao entendimento. São explicitações importantes que ajudam a compreender o potencial formativo da mídia e a dinâmica de como ela se alicerça na sociedade. Assim, a racionalidade estratégica e a comunicativa que leva ao entendimento apresentam-se no mundo do sistema e no mundo da vida, respectivamente. A partir desse fundamento teórico habermasiano pode-se compreender o processo midiático como acontecendo na esfera pública em forma de visibilidade e discursividade. Concretamente isso significa ter um instrumental de análise que possibilita compreender com mais lucidez os diferentes diálogos que resultam da inter-relação entre mídia e sociedade. Compreender a mídia na sua expressão em forma de visibilidade e discursividade possibilita uma reflexão mais ampla, profunda e lúcida em torno do papel que essa instituição desempenha na contemporaneidade ocidental e principalmente brasileira no processo formativo.

Institucionalização, expansão e consolidação da escola na Europa

A tendência geral da educação ocidental no período do século XVI ao XIX é a construção e a consolidação da escola estado, ou seja, a escola pública para todos. No século XVI temos o reaparecimento da escola de estado formulada por Aristóteles na antiguidade grega. No entanto, cumpre acrescentar que ela aparece em outras bases, em outro contexto e de formas diferentes. É nesse século que nascem duas concepções que irão vigorar no século XVII: a concepção que nasceu da reforma protestante defendida principalmente por Lutero e a concepção da própria igreja católica. De um lado tínhamos Lutero defendendo uma escola para todas as crianças e afirmando que o dever de manter essa escola é uma obrigação da autoridade política. Do outro lado estava a igreja católica que não aceitava essa nova concepção. O século marca a expansão da educação na Europa e isso se dá por causa das reformas religiosas. Um nome que merece destaque na pedagogia moderna é Comenius que com a sua didática magna. No século XVIII surge uma nova concepção de educação que enfatiza a necessidade de uma escola para os cidadãos. Rousseau é quem cria essa nova concepção sobre a criança e como essa deve ser tratada pela escola e pela família. Com a revolução industrial houve diversas mudanças sociais que refletiram no ensino. Cumpre ressaltar que a tônica principal desse século são os sistemas nacionais de educação.

Gestão democrática: autonomia e participação na Escola Estadual 11 de Agosto Umarizal/RN

The object of analysis of this work is the implementation of the election of director in the State School August 11, situated in the city of Umarizal, State of Rio Grande do Norte, period 2005-2008. The understanding of the politics concerning the school democratization, triggered in Brazilian society in the 1990s, requires taking into consideration the changes occurring in recent decades in the national and international, which impressed significant changes in the role and functions of the state. The election of a director is part of the policy of administrative decentralization and educational reform that focuses on the democratization of the management of public education with the involvement of social actors in decisions within the educational institutions as a way to address the problems that hinder the actions management education, especially school management. To better understand this process of political democratization of school management developed our analysis seeking to answer the following questions: implementation of direct election for a director ensures democratic management in schools? What are the ramifications for the school, caused by direct election on the school autonomy and participation of the subjects in school processes? From these questions, we set as standard for analysis of democratic management in schools of two dimensions: participation and autonomy within the school. For this we take as a theoretical and methodological literature: Pateman (1992); Rousseau (2010); Bourdieu (2007), Castoriadis (1991); Macpherson (1978); Marx; Engels (2007), among others dealing with participation, autonomy, decision power and election of director, and guidelines dealing with the democratization of school management. As data collection procedure, we use the semi-structured interviews and analysis of meeting minutes of the School Council and the Minutes of the final results of elections, to understand the empirical aspects of the implementation of the election of a director. The survey results indicate some progress and setbacks regarding the participation of subjects from issues relating to the school's educational project. Also underline the political interference as a factor crystallizer the centralization of power in the figure of the director as well as the advancement of the spaces that nurture the mobilization of political debate on the democratization of management. About the extent of autonomy observed that social actors to relate predominantly to the power of decision and the involvement of subjects in the school's actions
