10-14岁超常儿童的亲社会行为特点及影响因素

Is prosocial behavior of supernormal children distinguished from normal children? Is there any difference between the supernormal children’s prosocial behavior from different educational placement? What are the mechanisms underlying the difference? The aim of this study was to examine these issues. With multiple methods of prosocial behavior, including other-rating, self-rating and hypothetical dilemma, we investigated the 10 to 14 year-old children. Firstly, the development of prosocial behavior and its relationship with prosocial behavior was examined. Secondly, we investigated the features of supernormal children’s prosocial behavior and analysed its difference with normal children. Finally, we tried to find the difference of supernormal children’s prosocial behaviour from different educational placement, and the mechanisms underlying the difference, such as social value orientation and peer relation. The results are as follows: 1)The altruistic and compliant prosocial tendency of 14 year-old children was obviously lower than those younger children. Intelligence was positively related with altruistic and emotional prosocial tendency for 10 year-olds, and with prosocial behaviour of peer nominated for 12 year-olds. 2)There was no significant difference of prosocial behaviour between supernormal and normal children. The peer nominated prosocial behaviour of 12 year-old supernormal children was higher than of 11 and 13 years old supernormal children. In addition, girls’ other-rating prosocial behaviour was significantly higher than boys’, but no gender difference was detected in the prosocial behaviour of self-rating and hypothetical dilemma. 3)With regard to the supernormal children’s prosocial behaviour in different educational placement, we found that the prosocial degree of the supernormal children of homogeneous groups was higher than that of heterogeneous groups in the role-change of ultimatum game. 4)The supernormal children from different educational placement had different social value orientation. More supernormal children of homogeneous groups belonged to the type of group enhancement, while more supernormal children of heterogeneous groups belonged to the type of equality. The types of social value orientation did not have impact on the supernormal children’s prosocial behaviour from different educational placement. 5)Peer relation moderated the impact of different educational placement on supernormal children’s prosocial behaviour.

Uma ferramenta para o cadastro e gestão de metadados de obras de infraestrutura e imagens de satélite do projeto PAC 10.

O Programa de Aceleração do Crescimento do Governo Federal (PAC) é baseado no conceito de investimentos em infraestrutura que, aliados a medidas econômicas, visam estimular os setores produtivos e, ao mesmo tempo, levar benefícios sociais para todas as regiões do Brasil. A Casa Civil e o Gabinete de Segurança Institucional da Presidência da República, a Secretaria de Planejamento e Investimentos Estratégicos (SPI) do Ministério do Planejamento, Orçamento e Gestão, e a Empresa Brasileira de Pesquisa Agropecuária (Embrapa) do Ministério da Agricultura, Pecuária e Abastecimento são parceiros no Projeto 10 do PAC Embrapa (PAC 10) ? ?Monitoramento orbital das obras do PAC e avaliação dos seus impactos?, executado pela equipe da Gestão Territorial Estratégica (GTE) da área técnica da Embrapa Monitoramento por Satélite. Devido à variedade de obras, diversas são as informações necessárias para o seu acompanhamento. Para organizar todas as informações, foi criado um banco de metadados digital.

Prediction of GC retention values under various column temperature conditions from temperature programmed data

A numerical approach has been developed for the correlation of retention limes (total retention lime) with temperature in gas chromatography, which allows the calculation of retention parameters including retention index from data acquired under two or more different temperature program conditions. By using this procedure the optimization of temperature condition can be further achieved, especially when a temperature-programmed run is the most suitable mode in the preliminary development of an analytical method for the analysis of an unknown sample.

An empirical equation for the calculation of retention time with extrapolation of temperature in gas chromatography

An empirical equation is proposed to accurately correlate isothermal data over a wide range of temperature With the equation ln k = A* + B*/T-lambda the retention times of different solutes tested on OV-101, SE-54 and PEG 20M capillary columns have been achieved even when lambda is assigned a constant value of 1.7 Comparison with ln k = A + B/T and in k = c + d/T+ h/T-2, shows that the proposed equation is of higher accuracy and is applicable to extrapolation calculation, especially from data at high temperature to those at low temperature. Parameters A* and B* as well as A and B are also discussed. The linear correlation of A* and B* is weaker than that of A and B.
