Este estudo investiga evidências da influência de uma intervenção psicomotora lúdica na construção do pensamento operatório concreto e desempenho neuromotor de alunos com dificuldade de aprendizagem da 2ª série do ensino fundamental, de escola pública do Estado de São Paulo. Utiliza-se de método experimental. Manipula a intervenção psicomotora lúdica, (Variável Independente-VI), com o objetivo de verificar a sua possível influência no desempenho cognitivo relativo a noções de Conservação, Classificação, Seriação e Aritmética, assim como no neuromotor relativo a Agilidade e Orientação Direita-Esquerda (Variáveis Dependentes - VDs) - totalizando 6 VDs. A amostra compõe-se por 18 escolares, na faixa etária de 7 a 11 anos, de ambos os sexos, organizados em dois grupos: experimental (N=9) e controle (N=9). O procedimento experimental desenvolve-se em 16 sessões, constando de três etapas. Aos dois grupos são aplicados, individualmente, pré-teste (1ª etapa) e pós-teste (3ª etapa), constando de duas sessões individuais em cada etapa, com a utilização dos seguintes instrumentos: Provas Operatórias de Piaget, teste Piaget-Head de Orientação Direita-Esquerda e subteste de Aritmética do teste de Desempenho Escolar de Stein, teste de Shuttle Run . A 2ª etapa, exclusiva do grupo experimental, consta da intervenção psicomotora lúdica, em 12 sessões grupais de 50 minutos cada. Utilizou-se da prova de Wilcoxon, para comparação dos resultados entre os grupos. Os resultados referentes às noções de Classificação ( p=0,010), Seriação (p=0,034), Aritmética (p=0,157) e Orientação Direita- Esquerda (p=0,007), indicam que ocorreu uma diferença significativa estatisticamente, considerando-se que os participantes apresentaram desempenho superior nos pós-testes. Nas demais provas, foi observado melhor desempenho nos dois grupos, o que, portanto, não pode ser atribuído à intervenção. Conclui-se que o objetivo do trabalho foi atingido, visto que o programa mostrou-se eficiente para desenvolver o pensamento operatório e o neuromotor em relação a Orientação Direita-Esquerda dos participantes.(AU)

The estrogen receptor locus is associated with a major gene influencing litter size in pigs.

Identification of individual major genes affecting quantitative traits in livestock species has been limited to date. By using a candidate gene approach and a divergent breed cross involving the Chinese Meishan pig, we have shown that a specific allele of the estrogen receptor (ER) locus is associated with increased litter size. Female pigs from synthetic lines with a 50% Meishan background that were homozygous for this beneficial allele produced 2.3 more pigs in first parities and 1.5 more pigs averaged over all parities than females from the same synthetic lines and homozygous for the undesirable allele. This beneficial ER allele was also found in pigs with Large White breed ancestory. Analysis of females with Large White breed background showed an advantage for females homozygous for the beneficial allele as compared to females homozygous for the other allele of more than 1 total pig born. Analyses of growth performance test records detected no significant unfavorable associations of the beneficial allele with growth and developmental traits. Mapping of the ER gene demonstrated that the closest known genes or markers were 3 centimorgans from ER. To our knowledge, one of these, superoxide dismutase gene (SOD2), was mapped for the first time in the pig. Analysis of ER and these linked markers indicated that ER is the best predictor of litter size differences. Introgression of the beneficial allele into commercial pig breeding lines, in which the allele was not present, and marker-assisted selection for the beneficial allele in lines with Meishan and Large White background have begun.

Caracterização geométrica e mecânica de macrofibras poliméricas.

Uma grande diversidade de macrofibras poliméricas para reforço de concreto se encontram disponibilizadas hoje em dia. Por natureza estas fibras apresentam grande diversidade de características e propriedades. Estas variações afetam sua atuação como reforço no concreto. No entanto, não há normas brasileiras sobre o assunto e as metodologias de caracterização de normas estrangeiras apresentam divergências. Algumas normas definem que a caracterização do comportamento mecânico deva ser feita nos fios originais e outras que se devam utilizar métodos definidos para caracterização de materiais metálicos. A norma EN14889-2:2006 apresenta maior abrangência, mas deixa dúvidas quanto à adequação dos critérios de caracterização geométrica das fibras e não define um método de ensaio específico para sua caracterização mecânica. Assim, há a necessidade de estabelecimento de uma metodologia que permita a realização de um programa de controle de qualidade da fibra nas condições de emprego. Esta metodologia também proporcionaria uma forma de caracterização do material para estudos experimentais, o que permitiria maior fundamentação científica desses trabalhos que, frequentemente, fundamentam-se apenas em dados dos fabricantes. Assim, foi desenvolvido um estudo experimental focando a caracterização de duas macrofibras poliméricas disponíveis no mercado brasileiro. Focou-se o estudo na determinação dos parâmetros geométricos e na caracterização mecânica através da determinação da resistência à tração e avaliação do módulo de elasticidade. Na caracterização geométrica foi adotada como referência a norma europeia EN14889-2:2006. As medições do comprimento se efetuaram por dois métodos: o método do paquímetro e o método de análise de imagens digitais, empregando um software para processamento das imagens. Para a medição do diâmetro, além das metodologias mencionadas, foi usado o método da densidade. Conclui-se que o método do paquímetro, com o cuidado de esticar previamente as macrofibras, e o método das imagens digitais podem ser igualmente utilizados para medir o comprimento. Já parar determinar o diâmetro, recomenda-se o método da densidade. Quanto à caracterização mecânica, foi desenvolvida uma metodologia própria a partir de informações obtidas de outros ensaios. Assim, efetuaram-se ensaios de tração direta nas macrofibras coladas em molduras de tecido têxtil. Complementarmente, foi avaliado também o efeito do contato abrasivo das macrofibras com os agregados durante a mistura em betoneira no comportamento mecânico do material. Também se avaliou o efeito do método de determinação da área da seção transversal nos resultados medidos no ensaio de tração da fibra. Conclui-se que o método proposto para o ensaio de tração direta da fibra é viável, especialmente para a determinação da resistência à tração. O valor do módulo de elasticidade, por sua vez, acaba sendo subestimado. A determinação da área da seção da fibra através do método da densidade forneceu também os melhores resultados. Além disso, comprovou-se que o atrito das fibras com o agregado durante a mistura compromete o comportamento mecânico, reduzindo tanto a resistência quanto o módulo de elasticidade. Assim, pode-se afirmar que a metodologia proposta para o controle geométrico e mecânico das macrofibras poliméricas é adequada para a caracterização do material.

Imperial legacy? The EU's Developmental Model and the Crisis of the European Periphery. CES Papers - Open Forum #19, 2013-2014

The high hopes for rapid convergence of Eastern and Southern EU member states are increasingly being disappointed. With the onset of the Eurocrisis convergence has given way to divergence in the southern members, and many Eastern members have made little headway in closing the development gap. The EU´s performance compares unfavourably with East Asian success cases as well as with Western Europe´s own rapid catch-up to the USA after 1945. Historical experience indicates that successful catch up requires that less-developed economies to some extent are allowed to free-ride on an open international economic order. However, the EU´s model is based on the principle of a level-playing field, which militates against such a form of economic integration. The EU´s developmental model thus contrasts with the various strategies that have enabled successful catch up of industrial latecomers. Instead the EU´s current approach is more and more reminiscent of the relations between the pre-1945 European empires and their dependent territories. One reason for this unfortunate historical continuity is that the EU appears to have become entangled in its own myths. In the EU´s own interpretation, European integration is a peace project designed to overcome the almost continuous warfare that characterised the Westphalian system. As the sovereign state is identified as the root cause of all evil, any project to curtail its room of manoeuvre must ultimately benefit the common good. Yet, the existence of a Westphalian system of nation states is a myth. Empires and not states were the dominant actors in the international system for at least the last three centuries. If anything, the dawn of the age of the sovereign state in Western Europe occurred after 1945 with the disintegration of the colonial empires and thus historically coincided with the birth of European integration.

A new confirmatory Neisseria gonorrhoeae real-time PCR assay targeting the porA pseudogene

The Roche Cobas Amplicor system is widely used for the detection of Neisseria gonorrhoeae but is known to cross react with some commensal Neisseria spp. Therefore, a confirmatory test is required. The most common target for confirmatory tests is the cppB gene of N. gonorrhoeae. However, the cppB gene is also present in other Neisseria spp. and is absent in some N. gonorrhoeae isolates. As a result, laboratories targeting this gene run the risk of obtaining both false-positive and false-negative results. In the study presented here, a newly developed N. gonorrhoeae LightCycler assay (NGpapLC) targeting the N. gonorrhoeae porA pseudogene was tested. The NGpapLC assay was used to test 282 clinical samples, and the results were compared to those obtained using a testing algorithm combining the Cobas Amplicor System (Roche Diagnostics, Sydney, Australia) and an in-house LightCycler assay targeting the cppB gene (cppB-LC). In addition, the specificity of the NGpapLC assay was investigated by testing a broad panel of bacteria including isolates of several Neisseria spp. The NGpapLC assay proved to have comparable clinical sensitivity to the cppB-LC assay. In addition; testing of the bacterial panel showed the NGpapLC assay to be highly specific for N. gonorrhoeae DNA. The results of this study show the NGpapLC assay is a suitable alternative to the cppB-LC assay for confirmation of N. gonorrhoeae-positive results obtained with Cobas Amplicor.

The rapid screen of concussion: An evaluation of the non-word repetition test for use in mTBI research

Primary objectives: (1) To investigate the Nonword Repetition test (NWR) as an index of sub-vocal rehearsal deficits after mild traumatic brain injury (mTBI); (2) to assess the reliability, validity and sensitivity of the NWR; and (3) to compare the NWR to more sensitive tests of verbal memory. Research design: An independent groups design. Methods and procedures: Study 1 administered the NWR to 46 mTBI and 61 uninjured controls with the Rapid Screen of Concussion (RSC). Study 2 compared mTBI, orthopaedic and uninjured participants on the NWR and the Hopkins Verbal Learning Test (HVLT-R). Main outcomes and results: The NWR did not improve the diagnostic accuracy of the RSC. However, it is reliable and indexes sub-vocal rehearsal speed. These findings provide evidence that although the current form of the NWR lacks sensitivity to the impact of mTBI, the development of a more sensitive test of sub-vocal rehearsal deficits following mTBI is warranted.

Contrast discrimination and pattern masking: contrast gain control with fixed additive noise

We studied the visual mechanisms that serve to encode spatial contrast at threshold and supra-threshold levels. In a 2AFC contrast-discrimination task, observers had to detect the presence of a vertical 1 cycle deg-1 test grating (of contrast dc) that was superimposed on a similar vertical 1 cycle deg-1 pedestal grating, whereas in pattern masking the test grating was accompanied by a very different masking grating (horizontal 1 cycle deg-1, or oblique 3 cycles deg-1). When expressed as threshold contrast (dc at 75% correct) versus mask contrast (c) our results confirm previous ones in showing a characteristic 'dipper function' for contrast discrimination but a smoothly increasing threshold for pattern masking. However, fresh insight is gained by analysing and modelling performance (p; percent correct) as a joint function of (c, dc) - the performance surface. In contrast discrimination, psychometric functions (p versus logdc) are markedly less steep when c is above threshold, but in pattern masking this reduction of slope did not occur. We explored a standard gain-control model with six free parameters. Three parameters control the contrast response of the detection mechanism and one parameter weights the mask contrast in the cross-channel suppression effect. We assume that signal-detection performance (d') is limited by additive noise of constant variance. Noise level and lapse rate are also fitted parameters of the model. We show that this model accounts very accurately for the whole performance surface in both types of masking, and thus explains the threshold functions and the pattern of variation in psychometric slopes. The cross-channel weight is about 0.20. The model shows that the mechanism response to contrast increment (dc) is linearised by the presence of pedestal contrasts but remains nonlinear in pattern masking.

Regulatory price performance, excess cost indexes and profitability:how effective is price cap regulation in the water industry?

In this study we apply an index number approach to allow for cross sectional comparisons of relative profitability, productivity and price performance of the regulated Water and Sewerage companies (WaSCs) in England and Wales during the years 1991-2008. In order to better analyse the impact of regulation on WaSC performance, we decompose actual economic profits into spatial multilateral Fisher productivity (TFP) index, the inverse of which is demonstrated to be a regulatory excess cost index that measures the deviation of a firm’s actual costs from benchmark costs, and a newly developed regulatory total price performance (TPP) index, which measures the excess of regulated revenues relative to benchmark costs. Increases (decreases) in regulatory price performance are indicative of the loosening (tightening) of price cap regulation. Moreover, we also show that the relationship between actual economic profitability, regulatory excess costs and regulatory price performance indices can be used to categorize regulatory price caps as “weak”, “powerful” or “catch-up promoting”. The results indicated that throughout the entire 1991-2008 period, price caps were never “powerful”, in the sense that they required less productive firms to immediately and fully catch-up to the most productive firm to regain economic profitability. More specifically, during the years 1991-2000 price caps were “weak” as prices were high enough for the firms to achieve economic profits despite their low productivity levels. However, after 2001 prices became “catch up promoting” as they required less productive companies to eliminate at least some excess costs in order to eliminate economic losses. Finally, we emphasize that as our results also clearly demonstrated a much closer alignment between allowed revenues and benchmark costs after 2001, Ofwat’s approach during this period was not only appropriate, but should also be continued in the 2009 price review.

Intercultural training for international placements

Despite its increasing popularity, much intercultural training is not developed with the same level of rigour as training in other areas. Further, research on intercultural training has brought inconsistent results about the effectiveness of such training. This PhD thesis develops a rigorous model of intercultural training and applies it to the preparation of British students going on work/study placements in France and Germany. It investigates the reasons for inconsistent training success by looking at the cognitive learning processes in intercultural training, relating them to training goals, and by examining the short- and long-term transfer of intercultural training into real-life encounters with people from other cultures. Two cognitive trainings based on critical incidents were designed for online delivery. The training content relied on cultural practice dimensions from the GWBE study (House, Hanges, Javidan, Dorfman & Gupta, 2004). Of the two trainings, the 'singlemode training' aimed to develop declarative knowledge, which is necessary to analyse and understand other cultures. The 'concurrent training' aimed to develop declarative and procedural knowledge, which is needed to develop skills for dealing with difficult situations in a culturally appropriate way. Participants (N-48) were randomly assigned to one of the two training conditions. Declarative learning appeared as a process of steady knowledge increase, while procedural learning involved cognitive re-categorisation rather than knowledge increase. In a negotiation role play with host-country nationals directly after the online training, participants of the concurrent training exhibited a more initiative negotiation style than participants of the single-mode training. Comparing cultural adjustment and performance of training participants during their time abroad with an untrained control group, participants of the concurrent training showed the qualitatively best development in adjustment and performance. Besides intercultural training, multicultural personality traits were assessed and proved to be a powerful predictor of adjustment and, indirectly, of performance abroad.

Impact of high-performance work systems on individual- and branch-level performance:test of a multilevel model of intermediate linkages

We proposed and tested a multilevel model, underpinned by empowerment theory, that examines the processes linking high-performance work systems (HPWS) and performance outcomes at the individual and organizational levels of analyses. Data were obtained from 37 branches of 2 banking institutions in Ghana. Results of hierarchical regression analysis revealed that branch-level HPWS relates to empowerment climate. Additionally, results of hierarchical linear modeling that examined the hypothesized cross-level relationships revealed 3 salient findings. First, experienced HPWS and empowerment climate partially mediate the influence of branch-level HPWS on psychological empowerment. Second, psychological empowerment partially mediates the influence of empowerment climate and experienced HPWS on service performance. Third, service orientation moderates the psychological empowerment-service performance relationship such that the relationship is stronger for those high rather than low in service orientation. Last, ordinary least squares regression results revealed that branch-level HPWS influences branch-level market performance through cross-level and individual-level influences on service performance that emerges at the branch level as aggregated service performance. © 2011 American Psychological Association.

Performance management of event processing systems

This thesis is a study of performance management of Complex Event Processing (CEP) systems. Since CEP systems have distinct characteristics from other well-studied computer systems such as batch and online transaction processing systems and database-centric applications, these characteristics introduce new challenges and opportunities to the performance management for CEP systems. Methodologies used in benchmarking CEP systems in many performance studies focus on scaling the load injection, but not considering the impact of the functional capabilities of CEP systems. This thesis proposes the approach of evaluating the performance of CEP engines’ functional behaviours on events and develops a benchmark platform for CEP systems: CEPBen. The CEPBen benchmark platform is developed to explore the fundamental functional performance of event processing systems: filtering, transformation and event pattern detection. It is also designed to provide a flexible environment for exploring new metrics and influential factors for CEP systems and evaluating the performance of CEP systems. Studies on factors and new metrics are carried out using the CEPBen benchmark platform on Esper. Different measurement points of response time in performance management of CEP systems are discussed and response time of targeted event is proposed to be used as a metric for quality of service evaluation combining with the traditional response time in CEP systems. Maximum query load as a capacity indicator regarding to the complexity of queries and number of live objects in memory as a performance indicator regarding to the memory management are proposed in performance management of CEP systems. Query depth is studied as a performance factor that influences CEP system performance.
