Efeito do alerta e valência emocional nos componentes de lembrança e familiaridade da memória episódica

The episodic memory system allows us to retrieve information about events, including its contextual aspects. It has been suggested that episodic memory is composed by two independent components: recollection and familiarity. Recollection is related to the vivid e detailed retrieval of item and contextual information, while familiarity is the capability to recognize items previously seen as familiars. Despite the fact that emotion is one of the most influent process on memory, only a few studies have investigated its effect on recollection and familiarity. Another limitation of studies about the effect of emotion on memory is that the majority of them have not adequately considered the differential effects of arousal and positive/negative valence. The main purpose of the current work is to investigate the independent effect of emotional valence and arousal on recollection and familiarity, as well as to test some hypothesis that have been suggested about the effect of emotion on episodic memory. The participants of the research performed a recognition task for three lists of emotional pictures: high arousal negative, high arousal positive and low arousal positive. At the test session, participants also rated the confidence level of their responses. The confidence ratings were used to plot ROC curves and estimate the contributions of recollection and familiarity of recognition performance. As the main results, we found that negative valence enhanced the component of recollection without any effect on familiarity or recognition accuracy. Arousal did not affect recognition performance or their components, but high arousal was associated with a higher proportion of false memories. This work highlight the importance of to consider both the emotional dimensions and episodic memory components in the study of emotion effect on episodic memory, since they interact in complex and independent way

Produção, qualidade dos frutos e estado nutricional da laranja valência sob fertirrigação e adubação convencional

O objetivo deste trabalho foi comparar os efeitos de doses de nitrogênio, fósforo e potássio aplicadas via água de irrigação em comparação à aplicação convencional de fertilizantes, com irrigação e sem irrigação. O experimento foi conduzido em um pomar de laranja 'Valência' (Citrus sinensis Osbeck) localizado em Pratânia - SP, durante três anos consecutivos, e analisados os dados do último ano de observação. As diferentes formas de aplicação dos fertilizantes e a redução das doses fornecidas via água de irrigação não resultaram em diferenças significativas sobre o número médio de frutos e produtividade. Também não foram constatadas diferenças estatísticas dos tratamentos sobre a qualidade do suco e o estado nutricional das plantas, com exceção do teor de fósforo.

Valência do nome deverbal e nominalidade prototípica

O objetivo deste trabalho é mostrar que os nomes deverbais preservam a estrutura argumental do verbo input correspondente e que a especificação ou não dos argumentos no interior do termo nominal depende de um conjunto de fatores pragmáticos, especialmente relacionados a informação de curto termo compartilhada pelos participantes da interação. Como implicação teórica, a análise preserva a idéia de que há um processo gradual de descategorização verbal, que se reflete nos diferentes tipos de marcação gramatical. Conforme o predicado verbal ganha estatuto nominal, as marcações tipicamente oracionais dão lugar a outros mecanismos, como marcação argumental por preposição, modificação por adjetivo, uso de pronomes possessivos, que acompanham apropriadamente um núcleo nominal.

Época de sobressemeadura de gramíneas anuais de inverno e de verão no capim-Tifton 85: produção e composição botânica

The experiment was conducted at UNESP-Jaboticabal during the 2001-2002 winter-spring-summer periods to evaluate the herbage mass, botanical composition, dry matter production of mix pastures, and leaf: sheat-stem ration of Tifton 85 or overseeding with annual winter or summer species. The treatments were: pearl millet (Pennisetum americanum (L.) Leeke) plus bristeal oat (Avena strigosa Schreb); sorghum sudan grass (Sorghum bicolor (L.) Moench x Sorghum sudanense (Piper) Stapf) (SS AG2501 C) plus bristeal oat, overseeded on Tifton 85 area on 06/19/02/04, or 07/02/02, and Tifton 85, conducted in a randomized block design. The AG2501 contributed with a small participation in the botanical composition and the presence of millet in the experiment was not observed. Highest herbage mass at first and second evaluations related to first seeding time was 63% higher compared to the second seeding time. The herbage mass were similar he production in the other evaluations were similar. on the second seeding time, it was observed highest oat species in relation to the first seeding time. The leaf: sheat-stem ration decreased during the experiment due to the pasture botanical composition changes.

Taxonomic comments and an identification key to species for the Smooth-hound sharks genus Mustelus Link, 1790 (Chondrichthyes: Triakidae) from the Western South Atlantic.

Five species of smooth-hound sharks genus Mustelus (Family Triakidae) are know in the western South Atlantic, as follows: Mustelus canis (Mitchell 1815); Mustelus fasciatus (Garman 1913); Mustelus higmani Springer & Lowe 1963; Mustelus norrisi Springer 1939; and Mustelus schmitti Springer 1939. In the present paper, new data on the anatomy, morphometrics and meristic characters are given. Taxonomic aspects and comparison between the species are discussed. Most general body morphologic measurements and proportions are useless as a tool for species identification, since many of them show remarkable intraspecific variations. Head proportions and structures related seem to be a more adequate procedure to identify the species of Mustelus. The labial folds proportions, internasal distance and orbit diameter were the most useful character to separate the western South Atlantic species. The buccopharingeal pattern of denticles as well as tooth counts not was useful to distinguish the Mustelus species from western South Atlantic adequately, due great intraspecific variation.

Caracterização silvicultural, botânica e avaliação da variabilidade genética por meio do marcador molecular RAPD em um teste de progênies de Eucalyptus urophylla S. T. Blake

Molecular markers have recently been incorporated into genetic improvement programs. They are already considered as powerful tools with several different uses, for instance the monitoring of genetic variability in tree populations. The main objectives of this study were to evaluate genetic variability in Eucalyptus urophylla progenies and together with silvicultural and botanical information, provide assistance to the improvement program. The Eucalypts population is located at the Experimental Forestry Sciences Station, Anhembi, SP, which belongs to the College of Agriculture Luiz de Queiroz. Sixty-nine progenies were analysed representing one individual by family in open pollinated Eucalyptus urophylla trees. The RAPD technique allowed the identification of 72 loci that were analysed using Jaccard's Coefficient generating a genetic similarity matrix to permit estimation of genetic distances. The results obtained showed genetic distance between individuals of 0.40 with 12 groups of genetic variability using a standardised distance of 40%. The progenies showed different bark patterns, allowing the establishment of bark groups. The groups formed based on genetic distances obtained using DNA analysis did not correspond to those based on bark pattern. Genetic selection was simulated in which silvicultural and genetic variability data were linked, thus avoiding excessive variability losses. The simulation of controlled crossings allowed the maximum genetic difference to be obtained linked with height and individual bark roughness.

Avaliação dos teores nutricionais em laranjeira 'Valência', sob fertirrigação

This work aimed to compare fertigation to conventional fertilization in a five-year-old 'Valência' orange orchard, irrigated by microsprinklers. The conventional fertilization, using the recommended dosage for the crop, was parceled out in three during the year. In the fertigation treatments a complete dose, 1/2 and 1/3 of the conventional fertilization dose, parceled out in ten in a year, were used. Trunk circumference and leaf volume, leaf chlorophyll content and fruit yield and quality were measured. For the first year, significant differences among the treatments for the evaluated parameters were not observed; however, it was noticed that fertigation treatments caused less nutritional unbalance, obtained by DRIS. The fertigation treatment using half dosage showed the best result regarding to fruit yield and quality.
