This exploratory study is concerned with the performance of Egyptian children with Down syndrome on counting and error detection tasks and investigates how these children acquire counting. Observations and interviews were carried out to collect further information about their performance in a class context. Qualitative and quantitative analysis suggested a notable deficit in counting in Egyptian children with Down syndrome with none of the children able to recite the number string up to ten or count a set of five objects correctly. They performed less well on tasks which added more load on memory. The tentative finding of this exploratory study supported previous research findings that children with Down syndrome acquire counting by rote and links this with their learning experiences.

Duplication at the Xq28 band including the MECP2 gene is one of the most common genomic rearrangements identified in neurodevelopmentally delayed males. Such duplications are non-recurrent and can be generated by a non-homologous end joining (NHEJ) mechanism. We investigated the potential mechanisms for MECP2 duplication and examined whether genomic architectural features may play a role in their origin using a custom designed 4-Mb tiling-path oligonucleotide array CGH assay. Each of the 30 patients analyzed showed a unique duplication varying in size from similar to 250 kb to similar to 2.6 Mb. Interestingly, in 77% of these non-recurrent duplications, the distal breakpoints grouped within a 215 kb genomic interval, located 47 kb telomeric to the MECP2 gene. The genomic architecture of this region contains both direct and inverted low-copy repeat (LCR) sequences; this same region undergoes polymorphic structural variation in the general population. Array CGH revealed complex rearrangements in eight patients; in six patients the duplication contained an embedded triplicated segment, and in the other two, stretches of non-duplicated sequences occurred within the duplicated region. Breakpoint junction sequencing was achieved in four duplications and identified an inversion in one patient, demonstrating further complexity. We propose that the presence of LCRs in the vicinity of the MECP2 gene may generate an unstable DNA structure that can induce DNA strand lesions, such as a collapsed fork, and facilitate a Fork Stalling and Template Switching event producing the complex rearrangements involving MECP2.

Running hydrodynamic models interactively allows both visual exploration and change of model state during simulation. One of the main characteristics of an interactive model is that it should provide immediate feedback to the user, for example respond to changes in model state or view settings. For this reason, such features are usually only available for models with a relatively small number of computational cells, which are used mainly for demonstration and educational purposes. It would be useful if interactive modeling would also work for models typically used in consultancy projects involving large scale simulations. This results in a number of technical challenges related to the combination of the model itself and the visualisation tools (scalability, implementation of an appropriate API for control and access to the internal state). While model parallelisation is increasingly addressed by the environmental modeling community, little effort has been spent on developing a high-performance interactive environment. What can we learn from other high-end visualisation domains such as 3D animation, gaming, virtual globes (Autodesk 3ds Max, Second Life, Google Earth) that also focus on efficient interaction with 3D environments? In these domains high efficiency is usually achieved by the use of computer graphics algorithms such as surface simplification depending on current view, distance to objects, and efficient caching of the aggregated representation of object meshes. We investigate how these algorithms can be re-used in the context of interactive hydrodynamic modeling without significant changes to the model code and allowing model operation on both multi-core CPU personal computers and high-performance computer clusters.

Este estudo tem a finalidade de analisar experiências de interação Universidade – Empresa, em projetos do Instituto de Biotecnologia - ( IB ) da Universidade de Caxias do Sul – ( UCS ), a qual, como Instituição produtora e disseminadora de conhecimentos, busca atuar ativamente na transformação tecnológica da Região Nordeste do Estado do RS. Procura-se analisar as experiências de interação entre os pesquisadores da área de biotecnologia da UCS, as empresas do setor produtivo e a comunidade, identificando possíveis mecanismos e problemas. O IB foi criado para que, através dos resultados de suas pesquisas, possa contribuir efetivamente com os anseios da Comunidade a qual está inserida. Este estudo se constitui na análise de múltiplos casos de interação em oito projetos desenvolvidos no IB. Os dados foram coletados através de entrevistas com os coordenadores dos projetos no IB e com os responsáveis pela interação nas organizações parceiras, num total de 16 entrevistas.O estudo evidencia que as interações ocorrem a partir de contatos informais, baseadas na amizade entre os parceiros e oriundas, principalmente, do esforço do pesquisador. Os entrevistados acentuam a necessidade de uso de mecanismos formais de interação para agilizar e viabilizar projetos conjuntos do IB com empresas do setor produtivo e a comunidade, através de parcerias consolidadas. Finalmente, considera-se que, para assegurar o crescimento da interação com a comunidade, é urgente possibilitar, através de mecanismos formais, que a pesquisa científica desenvolvida no Instituto de biotecnologia da UCS volte-se prioritariamente para a identificação de problemas regionais, buscando as respectivas soluções, na perspectiva do desenvolvimento integrado da Região.

Programas de Fundos Competitivos para financiamento da pesquisa agrícola há muito estão sendo implementados nos países desenvolvidos. Entretanto, somente a partir da década de 1990 a adoção desse mecanismo se intensificou nos países em desenvolvimento, especialmente na América Latina. Isso ocorreu em razão da redução dos recursos do governo federal para a pesquisa agrícola, o que levou as instituições de pesquisa a buscar fontes alternativas para o financiamento de sua programação. A partir desse cenário, o presente trabalho analisa e discute a importância dos Fundos Competitivos como alternativa criativa e inovadora na captação de recursos para o financiamento da pesquisa agrícola no Brasil. A análise é feita a partir de estudo teórico sobre esse mecanismo de financiamento e com base em um estudo de caso do Sistema Competitivo do PRODETAB, implementado e coordenado pela Embrapa. O objetivo foi o de avaliar a importância e a contribuição dos fundos competitivos para o aumento da eficiência na alocação dos recursos públicos para a pesquisa agrícola e para a melhoria da qualidade dos projetos de pesquisa e desenvolvimento

The theory contemporary in the field of early children education, as well the legal discourse and official texts valid in our country point to the need for systematization of proposals pedagogic / curriculum in institutions, built and carried out by subjects that act as factor of assurance care quality. Quest us about what knowledge are required to teachers in developing a proposed curriculum for children education. Defined as an object of study, the knowledge teachers necessary for the development of a proposed curriculum for children education. As goals, assume: investigate teachers knowledge necessary for the development of a proposed curriculum in a Public Institution for children education and contribute to the (new) meaning on the part of teachers, knowledge needed to build a proposed curriculum for children education. Assuming the principles of the paradigm of qualitative research, we have developed a research institution of a children education Network Public Hall of Ceará-Mirim-RN, which serves children of four and five years old (preschool) with the participation of 17 teachers and two supervisory (teachers) that institution - subject of our research. Therefore, we have adopted the principles of action research, according to which the knowledge gained through research should build so shared / dialogue in the relationship between researcher and participants, what is the implementation of an effective action formative. As the search procedures developed observations no-teaching participants in the meetings and activities of the classroom; semi-structured interviews (individual and collective) with teachers and supervisors; analysis of school documents and participant observation in the seminars of studies reflective. The latter is implemented as key moments of speech and thought, and finally to (new) meaning of knowledge, the subject of the research-action. For these knowledge, the systematization of the register built was developed based on the principles of analysis of Content that guided us to the definition of two categories 1) knowledge teachers concerning conceptions of curriculum / proposed curriculum and 2) knowledge teachers concerning specifics of children education. From these were built subs representing thematings more specific and significant, among the many that emerged in the analysis: 1.1) Definitions of curriculum and curriculum proposal; 1.2) The subjects makers / implementing a curriculum / proposed curriculum; 1.3) elements constituting a curriculum / proposed curriculum for children education and 2.1) Functions of children education and conception of child; 2.2) The space of the play in the organization of routine. Under the intervention could significant advances with regard to (new) meaning of such knowledge from the subjects, with major disruptions to their original designs. These are presented and reflected in this work. In front of this movement, transformation, made the need for a permanent work in the context of the institution of in-service training, or mediated by pedagogical coordinator or other to assume this role with teachers, in order to provide the development and effectiveness of proposed curriculum consistent and contextualized in practice effective with the children concrete envisage the service to their specificities and a quality education

In the last decades, studies on early intervention involving children with autism have suggested that there is no single intervention model capable of addressing the needs of all individuals in the spectrum. The role of parents as active intervention agents is, however, highly recommended. The More Than Words-HANEN Program has been specifically created for parents of children, under five years of age, who are in the autism spectrum. This intervention aims at improving the social competence and language comprehension of the child, as well as their parents empowerment. Until now only three studies have been performed in order to evaluate the effectiveness of the HMTW program. The purpose of this investigation is to evaluate the effects of an early intervention program inspired on HMTW model on the level of caregiver responsiveness and child communication skills. The present study adds to the existing research literature on family-centered early intervention that uses a developmental paradigm. A two year boy in risk for autism, his mother and nanny took part in this investigation, which was carried out in the child´s home in Mossoró, Rio Grande do Norte. The caretakers were given one fifty-two hours of training, divided into thirteen weekly meetings. A quasi-experimental A-B-C design (baselineintervention- follow-up) showed improvement in the caretakers level of responsiveness and meaningful social-communicative gains in the child´s response
