Teacher knowledge, child interest and parent expectation: Factors influencing multicultural programs in an early childhood setting

© 2015, Early Childhood Australia Inc. All rights reserved. MULTICULTURAL CURRICULA/PROGRAMS assume an important role within a cultural approach to learning and teaching in early childhood education in New Zealand. Te Whariki, the national early childhood curriculum framework of New Zealand, is an emancipatory and socially constructive document that emphasises equity, social justice and the important position of culture in children's learning and development. In practice this means developing early childhood programs that are sensitive and responsive to the needs and interests of children and families of minority cultures. Drawing on a critical social constructivist framework, this study of one early childhood centre in New Zealand identifies the features of its multicultural curriculum. The paper argues that a devotion to supporting children of minority cultures has persisted in the curriculum, but there is a reliance on mainstream pedagogy focused on children's learning within the centre environment and teachers' subjective knowledge about children's needs.

Investigating the effects of personality traits on pair programming in a higher education setting through a family of experiments

Evidence from our systematic literature review revealed numerous inconsistencies in findings from the Pair Programming (PP) literature regarding the effects of personality on PP's effectiveness as a pedagogical tool. In particular: i) the effect of differing personality traits of pairs on the successful implementation of pair-programming (PP) within a higher education setting is still unclear, and ii) the personality instrument most often used had been Myers-Briggs Type Indicator (MBTI), despite being an indicator criticized by personality psychologists as unreliable in measuring an individual's personality traits. These issues motivated the research described in this paper. We conducted a series of five formal experiments (one of which was a replicated experiment), between 2009 and 2010, at the University of Auckland, to investigate the effects of personality composition on PP's effectiveness. Each experiment looked at a particular personality trait of the Five-Factor personality framework. This framework comprises five broad traits (Openness to experience, Conscientiousness, Extraversion, Agreeableness, and Neuroticism), and our experiments focused on three of these - Conscientiousness, Neuroticism, and Openness. A total of 594 undergraduate students participated as subjects. Overall, our findings for all five experiments, including the replication, showed that Conscientiousness and Neuroticism did not present a statistically significant effect upon paired students' academic performance. However, Openness played a significant role in differentiating paired students' academic performance. Participants' survey results also indicated that PP not only caused an increase in satisfaction and confidence levels but also brought enjoyment to the tutorial classes and enhanced students' motivation.

Price setting and macroeconomic variables: evidence from Brazilian CPI

Esta tese investiga as estratégias de precificação em ambientes macroeconômicos distintos, utilizando uma base de dados única para o IPC da Fundação Getulio Vargas. A base de dados primária consiste em um painel de dados individuais para bens e serviços representando 100% do IPC para o período de 1996 a 2008. Durante este período, diversos eventos produziram uma variabilidade macroeconômica substancial no Brasil: duas crises em países emergentes, uma mudança de regime cambial e monetário, racionamento de energia, uma crise de expectativas eleitorais e um processo de desinflação. Como consequência, a inflação, a incerteza macroeconômica, a taxa de câmbio e o produto exibiram uma variação considerável no período. No primeiro capítulo, nós descrevemos a base de dados e apresentamos as principais estatísticas de price-setting para o Brasil. Em seguida, nos capítulos 2 e 3, nos construímos as séries de tempo destas estatísticas e das estatísticas de promoções, e as relacionamos com as variáveis macroeconômicas utilizando análises de regressões. Os resultados indicam que há uma relação substancial entre as estatísticas de price-setting e o ambiente macroeconômico para a economia brasileira.

Exploratory semiparametric analysis of two-dimensional diffusions in finance

We examine bivariate extensions of Aït-Sahalia’s approach to the estimation of univariate diffusions. Our message is that extending his idea to a bivariate setting is not straightforward. In higher dimensions, as opposed to the univariate case, the elements of the Itô and Fokker-Planck representations do not coincide; and, even imposing sensible assumptions on the marginal drifts and volatilities is not sufficient to obtain direct generalisations. We develop exploratory estimation and testing procedures, by parametrizing the drifts of both component processes and setting restrictions on the terms of either the Itô or the Fokker-Planck covariance matrices. This may lead to highly nonlinear ordinary differential equations, where the definition of boundary conditions is crucial. For the methods developed, the Fokker-Planck representation seems more tractable than the Itô’s. Questions for further research include the design of regularity conditions on the time series dependence in the data, the kernels actually used and the bandwidths, to obtain asymptotic properties for the estimators proposed. A particular case seems promising: “causal bivariate models” in which only one of the diffusions contributes to the volatility of the other. Hedging strategies which estimate separately the univariate diffusions at stake may thus be improved.

Mobilidades Urbanas - Brevíssimas notas sobre o projeto 'Emerging Middle Classes and Low Carbon Mobilities: Setting long term foundations for transnational research'

Em uma conjuntura de expansão urbana, intensificação do consumo, mudança climática e escassez de petróleo, o tema das mobilidades assume inquestionável importância econômica, social e ambiental. O seminário internacional "Mobilidades Urbanas: Alicerces para Pesquisas Transnacionais" volta-se, por um lado, para a fomentação do debate em torno do paradigma das novas mobilidades - envolvendo mobilidade espacial e socioeconômica, entre outras - e de sua aplicabilidade no contexto brasileiro; por outro, para a capacitação de pesquisadores cujas investigações tematizam os processos de mobilidade social e espacial a partir de perspectivas comparativas e transnacionais.

Projeto de transposição de águas do Rio São Francisco: uma análise à luz do processo de agenda-setting

Quais condições permitiram que o Projeto de Transposição de Águas do Rio São Francisco deixasse de figurar no imaginário daqueles que o defendiam, como o vinha sendo desde os idos do período imperial, e, começasse a ser efetivamente implementado somente em 2007? Responder a esta questão corresponde ao objetivo principal deste estudo. Para tal, o Projeto São Francisco, como também é conhecido, foi analisado à luz do modelo de multiple streams, concebido por John Kingdon (2003), orientado para a compreensão sobre como algumas questões passam a fazer parte da agenda de governo, recebendo atenção dos formuladores de políticas públicas, enquanto outras são ignoradas. Por meio do modelo de multiple streams, foi possível apontar os principais diagnósticos e alternativas historicamente apresentados para a região do semiárido brasileiro, frente à questão dramática das secas recorrentes. Além disso, foi estruturado o complexo jogo político da transposição, caracterizado pelo conflito entre coalizões atuantes em múltiplas arenas decisórias. A partir do mapeamento da forma como os atores políticos se apropriaram dos diagnósticos e alternativas apresentados para a região, com o intuito de impor aos demais as suas crenças sobre qual deve ser o melhor caminho para o desenvolvimento do semiárido, foram identificadas as janelas de oportunidades (policy windows) que tornaram viáveis a execução do projeto de transposição.

Acompanhamento terapêutico como dispositivo da reforma psiquiátrica : considerações sobre o setting

Este trabalho estuda uma modalidade de atenção em saúde denominada acompanhamento terapêutico, que é importante ferramenta para o tratamento de sujeitos psicóticos e útil para a Reforma Psiquiátrica. Estuda-se o setting do AT, a fim de estabelecer uma relação possível entre os conceitos psicanalíticos e as singularidades que esta modalidade propõe, problematizando-as através dos seguintes conceitos: dispositivo, acaso/acontecimento e cidade. Busca-se algumas respostas às seguintes questões: Como se estabelece uma relação que propicie o surgimento de um encontro entre acompanhante e acompanhado? No acompanhamento terapêutico como poderíamos pensar um início de tratamento? O que de fato ocorre ou precisa acontecer? O que significa isto do ponto de vista da psicanálise e considerando que estamos trabalhando com sujeitos psicóticos? Qual o espaço de trabalho, ou melhor dizendo, o setting do AT? Que conceitos estão em jogo nesse setting. Podemos nos apoiar nas descobertas freudianas ainda que o setting seja sabidamente diferente? Que problemas isso acarreta desde o ponto de vista técnico? A metodologia é o estudo de caso único. Utiliza-se como fonte os registros de um atendimento, entrevistas e o material escrito produzido pelo próprio sujeito acompanhado. Escolheu-se cenas ilustrativas do caso atendido vinculando-as à teorização apresentada. Entende-se o acompanhamento terapêutico como importante dispositivo clínico e político do processo da Reforma Psiquiátrica. O acompanhante terapêutico é um agente que transita entre os espaços de tratamento (o dentro) e os demais espaços sociais (o fora) com uma visão desinstitucionalizante e com o objetivo de auxiliar os sujeitos a ressignificarem seu lugar social.

Ionized-air-treated curaua fibers as reinforcement for phenolic matrices

Curaua fibers were treated with ionized air to improve the fiber/phenolic matrix adhesion.The treatment with ionized air did not change the thermal stability of the fibers. The impact strength increased with increase in the fiber treatment time. SEM micrographs of the fibers showed that the ionized air treatment led to separation of the fiber bundles. Treatment for 12 h also caused a partial degradation of the fibers, which prompted the matrix to transfer the load to a poorer reinforcing agent during impact, thereby decreasing the impact strength of the related composite. The composites reinforced with fibers treated with ionized air absorbed less water than those reinforced with untreated fibers.

Genotyping of Mycobacterium tuberculosis isolates from alow-endemic setting in northwestern state of Paraná in Southern Brazil

The purpose of this study was to provide information about the genetic diversity and prevalent genotype of Mycobacterium tuberculosis in a low-endemic setting in northwestern state of Paraná in Southern Brazil. We employed spoligotyping and mycobacterial interspersed repetitive units-variable number tandem repeat (MIRU-VNTR) techniques to genotype M. tuberculosisisolates from patients with pulmonary tuberculosis (TB). The 93 isolates analyzed by spoligotyping were divided into 36 different patterns, 30 of which were described in the SITVIT database. Latin American and Mediterranean, Haarlem and T families were responsible for 26.9%, 17.2% and 11.8% of TB cases, respectively. From the 84 isolates analyzed by MIRU-VNTR, 58 shared a unique pattern and the remaining 26 belonged to nine clusters. The MIRU loci 40, 23, 10 and 16 were the most discriminatory. A combination of MIRU-VNTR and spoligotyping resulted in 85.7% discriminatory power (Hunter-Gaston index = 0.995). Thus, combining spoligotyping and MIRU-VNTR typing proved to be most useful for epidemiological study in this low-endemic setting in Southern Brazil. The current study demonstrated that there is significant diversity in circulating strains in the city of Maringá and the surrounding regions, with no single genotype of M. tuberculosispredominating.

Setting the preheating and steady-state operation of electronic ballasts, considering electrodes of hot-cathode fluorescent lamps

This paper presents a new methodology for the adjustment of the preheating process and steady-state operation of electronic ballasts intended for hot-cathode fluorescent lamps. The classical series-resonant parallel-loaded half-bridge inverter is the power stage analyzed in this paper. In addition, the preheating process is based on the imposition of a constant rms current through the electrodes, in order to provide a proper value of the R-h/R-c ratio before the lamp start. According to the proposed methodology, it is possible to set suitable operating points for, the electronic ballast, considering optimal conditions for the lamps electrodes. Therefore, the proposed methodology for setting the preheating and steady-state operation is a complete platform to the design of electronic ballasts for hot-cathode fluorescent lamps.

Single real transformation matrices applied to double three-phase transmission lines

Single real transformation matrices are tested as phase-mode transformation matrices of typical symmetrical systems with double three-phase and two parallel double three-phase transmission lines. These single real transformation matrices are achieved from eigenvector matrices of the mentioned systems and they are based on Clarke's matrix. Using linear combinations of the Clarke's matrix elements, the techniques applied to the single three-phase lines are extended to systems with 6 or 12 phase conductors. For transposed double three-phase lines, phase Z and Y matrices are changed into diagonal matrices in mode domain. Considering non-transposed cases of double three-phase lines, the results are not exact and the error analyses are performed using the exact eigenvalues. In case of two parallel double three-phase lines, the exact single real transformation matrix has not been obtained yet. Searching for this exact matrix, the analyses are based on a single homopolar reference. For all analyses in this paper, the homopolar mode is used as the only homopolar reference for all phase conductors of the studied system. (C) 2008 Elsevier B.V. All rights reserved.
