o estudo da relação entre a complexidade do conhecimento e sua construção no ambiente escolar apóia-se na Epistemologia Genética e no paradigma da complexidade. A investigação se delineou como um estudo qualitativo, inspirado na metodologia de Estudo de Caso. O problema de pesquisa procurou indagar a repercussão da fragmentação dos conteúdos programáticos em disciplinas nos anos finais do Ensino Fundamental. Os dados foram coletados através de múltiplas fontes de evidência. Realizaram-se entrevistas, inspiradas na abordagem clínica piagetiana, com alunos e professores; - observações diretas do tipo participante como observador e análise documental. Os dados coletados indicam que as práticas escolares apresentam pressupostos epistemológicos e paradigmáticos que se apóiam no senso comum e estendem-se em métodos empiristas/aprioristas e reducionistas. O pensamento do aluno é manipulado de forma a se enquadrar ao modelo escolar. A fala é reduzida a uma mera ação prática, pois, embora exercida, o professor desconsidera a importância do diálogo. Por sua vez, os exercícios apresentam-se como dois lados de uma mesma moeda. Podem manifestar-se como promotores de técnicas empiristas, quando colocados sob a forma de repetição para a memorização. Todavia, podem se revelar como um recurso extremamente valioso quando colocam um problema, apresentam desafios e permitem a testagem de hipóteses do sujeito. Já os conteúdos programáticos visam a uma eterna diferenciação do objeto de estudo, a qual se configura como uma simples fragmentação capaz de eliminar qualquer dimensão do conhecimento enquanto totalidade. O tempo da aprendizagem acaba por se igualar com aquele que o professor gasta para expor a informação ao aluno. Isso o relega a uma posição passiva que retira o caráter de equilíbrio dinâmico do conhecimento, pois esse sempre se apresenta como um produto pronto e acabado. A escola, então, tem um desconhecimento do próprio conhecimento e o senso comum, que é empirista/apriorista no campo epistemológico, é reducionista em sua dimensão paradigmática.

The present study has the objective to analyze with teachers from Elementary School the knowledge mobilized in the organization of the teaching-learning process, and its implications in the exploitation of that process. The investigation was developed with two teachers from the first years of the Elementary School, from a public school in Pau dos Ferros-RN. It adopts as basis the notion of knowledge as a set of individual and social relations that the individuals maintain with the world and with themselves, in the teaching and learning relation. (CHARLOT, 2000). It considers yet that the knowledges are immediate processes, reconstructed and mobilized by the practice of reflection, in dialogical and interactional contexts in contact with others. (BAKHTIN, 2002, 2003; VYGOTSKY, 1991, 2004, 2005). The collaborative approach was the theoretical and methodological background that oriented the investigative-educative process. By choosing a collaborative research as basis of the investigative pathway, it starts from the knowledge that the critical and collaborative reflection developed with the teachers from the first years of the Elementary School contribute to explicitate and resignify the meanings assigned to the knowledges that these teachers mobilize in the organization of the teaching-learning and its implications in this process. The results of the reflexive and investigative process developed with the teachers demonstrate that the familiar, scholastic, academic, professional, and the work knowledges lived, constitute the consciousness of being a teacher, and that these knowledges implicate in the dynamics of the process of teaching-learning, but not always the teachers take consciousness about these knowledges. The critical and collaborative reflection, mediated by the actions of describing, announcing, facing and reconstructing allowed to the participants of the research to realize the knowledges of themselves and of the other, the difficulties and possibilities in the organization of the teaching-learning process

Fundamental Sounds was a live, intercultural and multidisciplinary concert that presented a new synthesis of music, performance & visual arts addressing the imperative of sustainability in a new and evocative form. The outcome was a ninety-minute concert, performed at a major concert hall venue, involving four live musicians, numerous performers & large-scale projections. The images and the concert were scripted in three key phases that spoke to three epochs of human evolution identified by ontological designer and futurist Tony Fry - ‘Pre-Settlement’, ‘Settlement’ and the era that he suggests that we have now entered – ‘Unsettlement’ (in mind body and spirit). The entire work was professionally recorded for presentation on DVD and audio CD.----- Fundamental Sounds achieved a new synthesis between quality performance forms and cogent critical ideas, engendering an increasingly reflective position for audiences around today’s “era of unsettlement” – an epoch Fry has recognized that we must now move to quickly displace through adopting fundamentally sustainable modes of being and becoming.----- The concert was well attended and evoked a range of strong, reflective reactions from its audiences who were also invited to join and participate within a subsequent ‘community of change’ initiated at that time.

In this paper, we consider a time-space fractional diffusion equation of distributed order (TSFDEDO). The TSFDEDO is obtained from the standard advection-dispersion equation by replacing the first-order time derivative by the Caputo fractional derivative of order α∈(0,1], the first-order and second-order space derivatives by the Riesz fractional derivatives of orders β 1∈(0,1) and β 2∈(1,2], respectively. We derive the fundamental solution for the TSFDEDO with an initial condition (TSFDEDO-IC). The fundamental solution can be interpreted as a spatial probability density function evolving in time. We also investigate a discrete random walk model based on an explicit finite difference approximation for the TSFDEDO-IC.

Facebook has clocked up some 400 million registered users worldwide; Twitter has just reached the 100 million mark. Within these communities, Australians appear to be particularly active: we lead the world by spending nearly eight hours per month using social media. These figures highlight the fact that for most businesses, social media are now important for engaging with customers.

The practice of robotics and computer vision each involve the application of computational algorithms to data. The research community has developed a very large body of algorithms but for a newcomer to the field this can be quite daunting. For more than 10 years the author has maintained two open-source MATLAB® Toolboxes, one for robotics and one for vision. They provide implementations of many important algorithms and allow users to work with real problems, not just trivial examples. This new book makes the fundamental algorithms of robotics, vision and control accessible to all. It weaves together theory, algorithms and examples in a narrative that covers robotics and computer vision separately and together. Using the latest versions of the Toolboxes the author shows how complex problems can be decomposed and solved using just a few simple lines of code. The topics covered are guided by real problems observed by the author over many years as a practitioner of both robotics and computer vision. It is written in a light but informative style, it is easy to read and absorb, and includes over 1000 MATLAB® and Simulink® examples and figures. The book is a real walk through the fundamentals of mobile robots, navigation, localization, arm-robot kinematics, dynamics and joint level control, then camera models, image processing, feature extraction and multi-view geometry, and finally bringing it all together with an extensive discussion of visual servo systems.

Decades of intervention have made variable impact on the inequality between indigenous and non-indigenous well-being across the world. Unacceptable differences in life expectancy alone mark indigenous need as an area where greater understanding of public and private funding approaches and their interaction may deliver real benefits. Both the public and the third sector have been active in trying to address the disadvantage experienced by Australia’s indigenous people. The interaction between the indigenous cause philanthropy system and the wider geopolitical landscape in Australia is revealing barriers and insights that may apply in other challenging policy terrain. The research reported here draws upon two empirical studies aimed at understanding the issues facing philanthropy in Australia,including the impact of government agency both independently and as it contrasts with philanthropy. The two different cultures are evident and two levers (greater system flexibility and closer engagement) are suggested as important in moving forward the philanthropy/government relationship in this area.

This paper describes the formulation for the free vibration of joined conical-cylindrical shells with uniform thickness using the transfer of influence coefficient for identification of structural characteristics. These characteristics are importance for structural health monitoring to develop model. This method was developed based on successive transmission of dynamic influence coefficients, which were defined as the relationships between the displacement and the force vectors at arbitrary nodal circles of the system. The two edges of the shell having arbitrary boundary conditions are supported by several elastic springs with meridional/axial, circumferential, radial and rotational stiffness, respectively. The governing equations of vibration of a conical shell, including a cylindrical shell, are written as a coupled set of first order differential equations by using the transfer matrix of the shell. Once the transfer matrix of a single component has been determined, the entire structure matrix is obtained by the product of each component matrix and the joining matrix. The natural frequencies and the modes of vibration were calculated numerically for joined conical-cylindrical shells. The validity of the present method is demonstrated through simple numerical examples, and through comparison with the results of previous researchers.
