We investigated cross-cultural differences in the factor structure and psychometric properties of the 75-item Young Schema Questionnaire-Short Form (YSQ-SF). Participants were 833 South Korean and 271 Australian undergraduate students. The South Korean sample was randomly divided into two sub-samples. Sample A was used for Exploratory Factor Analysis (EFA) and sample B was used for Confirmatory Factor Analysis (CFA). EFA for the South Korean sample revealed a 13-factor solution to be the best fit for the data, and CFA on the data from sample B confirmed this result. CFA on the data from the Australian sample also revealed a 13-factor solution. The overall scale of the YSQ-SF demonstrated a high level of internal consistency in the South Korean and Australian groups. Furthermore, adequate internal consistencies for all subscales in the South Korean and Australian samples were demonstrated. In conclusion, the results showed that YSQ-SF with 13 factors has good psychometric properties and reliability for South Korean and Australian University students. Korean samples had significantly higher YSD scores on most of the 13 subscales than the Australian sample. However, limitations of the current study preclude the generalisability of the findings to beyond undergraduate student populations. (c) 2006 Elsevier B.V. All rights reserved.

O tema desta pesquisa é a formação do discurso da responsabilidade social empresarial por meio da revista especializada publicada pelo Conselho Empresarial Brasileiro para o Desenvolvimento Sustentável (CEBDS), a Brasil Sustentável. A análise de um veículo de comunicação especializado no tema da responsabilidade social tem o objetivo de definir características que concorram para a elaboração de um discurso que ganha divulgação e relevância na sociedade, e assim contribuir para uma melhor compreensão desse fenômeno. Levando-se em conta um cenário de transformações do capitalismo no pós-moderno, o trabalho vai investigar como ocorre o processo de ressignificação do papel da empresa privada para uma nova inserção na agenda política de debates. O trabalho será desenvolvido com a base teórica das formulações da análise do discurso (AD), utilizando-se seus conceitos e ferramentas para um estudo do discurso da responsabilidade social empresarial inscrito num quadro social e histórico ampliado.(AU)

Resiliência é um termo relativamente novo no campo da psicologia e nos debates acadêmicos e que tem suscitado muito interesse por parte dos pesquisadores, em especial os do campo da Psicologia da Saúde, pois se trata de um conceito que carrega grande potencial em termos de prevenção de doenças e promoção da saúde, seja focado no plano social, comunitário ou individual. Em resumo, resiliência consiste na capacidade dos seres humanos de superarem as adversidades da vida e, além disso, saírem fortalecidos após uma situação problema. Estudos têm mostrado que pessoas consideradas resilientes possuem atributos pessoais que as ajudam a obter êxito diante das adversidades. No entanto, as medidas do construto não representam essa abrangência. Por isso, o objetivo deste estudo foi construir e validar uma escala que avalie as características pessoais mais referenciadas na literatura. No total, foram identificados 15 atributos pessoais da resiliência mencionados por mais de cinco autores. Com base neles foi construída a Escala dos Pilares da Resiliência (EPR) com 150 itens. Participaram da coleta de dados 833 estudantes e trabalhadores do Estado de São Paulo e Santa Catarina, com idade média de 30,70 (DP= 10,58), sendo a maioria do gênero feminino (70,5%) e solteiros(as) (59,8%) com escolaridade de ensino fundamental até pós-graduação. Por meio de um questionário coletaram-se dados sociodemográficos dos participantes. Foram calculadas estatísticas descritivas, análise fatorial, correlação item-total e alfa de Cronbach. Os resultados revelaram um modelo de 11 fatores que reuniram 90 itens com boas cargas fatoriais. As correlações item-total tiveram valores considerados satisfatórios e os fatores apresentaram bons índices de precisão. A EPR reuniu o maior número de atributos pessoais da resiliência dentre os instrumentos encontrados na revisão deste trabalho. A escala pode ser utilizada em novos estudos e será normatizada em futuro próximo.

The objective of this work has been to study the behaviour and performance of a batch chromatographic column under simultaneous bioreaction and separation conditions for several carbohydrate feedstocks. Four bioreactions were chosen, namely the hydrolysis of sucrose to glucose and fructose using the enzyme invertase, the hydrolysis of inulin to fructose and glucose using inulinase, the hydrolysis of lactose to glucose and galactose using lactase and the isomerization of glucose to fructose using glucose isomerase. The chromatographic columns employed were jacketed glass columns ranging from 1 m to 2 m long and the internal diameter ranging from 0.97 cm to 1.97 cm. The stationary phase used was a cation exchange resin (PUROLITE PCR-833) in the Ca2+ form for the hydrolysis and the Mg2+ form for the isomerization reactions. The mobile phase used was a diluted enzyme solution which was continuously pumped through the chromatographic bed. The substrate was injected at the top of the bed as a pulse. The effect of the parameters pulse size, the amount of substrate solution introduced into the system corresponding to a percentage of the total empty column volume (% TECV), pulse concentration, eluent flowrate and the enzyme activity of the eluent were investigated. For the system sucrose-invertase complete conversions of substrate were achieved for pulse sizes and pulse concentrations of up to 20% TECV and 60% w/v, respectively. Products with purity above 90% were obtained. The enzyme consumption was 45% of the amount theoretically required to produce the same amount of product as in a conventional batch reactor. A value of 27 kg sucrose/m3 resin/h for the throughput of the system was achieved. The systematic investigation of the factors affecting the performance of the batch chromatographic bioreactor-separator was carried out by employing a factorial experimental procedure. The main factors affecting the performance of the system were the flowrate and enzyme activity. For the system inulin-inulinase total conversions were also obtained for pulses sizes of up to 20 % TECV and a pulse concentration of 10 % w/v. Fructose rich fractions with 100 % purity and representing up to 99.4 % of the total fructose generated were obtained with an enzyme consumption of 32 % of the amount theoretically required to produce the same amount of product in a conventional batch reactor. The hydrolysis of lactose by lactase was studied in the glass columns and also in an SCCR-S unit adapted for batch operation, in co-operation with Dr. Shieh, a fellow researcher in the Chemical Engineering and Applied Chemistry Department at Aston University. By operating at up to 30 % w/v lactose feed concentrations complete conversions were obtained and the purities of the products generated were above 90%. An enzyme consumption of 48 % of the amount theoretically required to produce the same amount of product in a conventional batch reactor was achieved. On working with the system glucose-glucose isomerase, which is a reversible reaction, the separation obtained with the stationary phase conditioned in the magnesium form was very poor although the conversion obtained was compatible with those for conventional batch reactors. By working with a mixed pulse of enzyme and substrate, up to 82.5 % of the fructose generated with a purity of 100 % was obtained. The mathematical modelling and computer simulation of the batch chromatographic bioreaction-separation has been performed on a personal computer. A finite difference method was used to solve the partial differential equations and the simulation results showed good agreement with the experimental results.
