O Modelo Grupo Prático de Deslocamentos em Psicologia e Epistemologia Genéticas e sua Formalização

In this article, we aim to describe and explain what is the model “practical group of displacements”, introduced in 1937 by Piaget’s work La construction du reel chez l’enfant (Neuchâtel, Paris: Delachaux et Niestlé), essential to comprehension of the construction of space. To this end, we introduce the mathematical notation to describe it, we give the meaning of this notation in the child’s behavior and explains the mathematical structure of group underlying the model.

Estudo sobre o acento secundário e a tonicidade dos monossílabos em português arcaico por meio da música e da métrica das Cantigas de Santa Maria

This paper aims to make a study on secondary stress and stress of monosyllabic words in Archaic Portuguese. With regard to secondary stress, our intention is to demonstrate its limits of occurrence. And about monosyllabic words, the aim is to analyse its stress attribution and the possibility of those words assume prominences in the linguistic level demonstrating or not its prosodic independence. The data will be collected by means of a new methodology in the study of the prosody of dead language. This methodology is based on the observation of coincidences and non-coincidences of musical prominences of poetic texts with musical notation, and linguistic prominences.

Músicas populares urbanas, relaciones de género y persistencia de prejuicios: datos brasileños y españoles a partir de la escucha de cuatro canciones.

Las músicas populares urbanas participan en la construcción, transmisión y deconstrucción de las imágenes de género. Es trascendental comprender su influencia entre los oyentes. Para ello, realizamos una investigación basada en encuestas a jóvenes universitarios que mostró la permanencia de prejuicios y una escasa capacidad crítica, lo que refuerza algunas de las hipótesis de la sociología de la música de T. W. Adorno y plantea cuestiones importantes para la musicología feminista. Es necesario tener conciencia de la existencia de estos prejuicios si pretendemos una educación emancipatoria.

O acento secundário no português arcaico

This paper aimsto study secondary stressinArchaic Portuguese demonstrating its limits of occurrence and its behavior through the Metrical Theory by Hayes (1995). The data was collected by means of a new methodology in the study of the prosody of ancient periods of the language. This methodology is based on the observation of matching and mismatching of musical and linguistic prominences of poetic texts with musical notation.

Proparoxítonas no português arcaico: uma análise por meio da música e do texto das Cantigas de Santa Maria

This paper aims to conduct a study on proparoxytones in Medieval Portuguese through an innovative methodology based on the observation of coincidences and no-coincidences of musical and linguistic prominences of poetic texts with musical notation.. This methodology allowed us to verify the existence of a hundred and thirteen proparoxytones words in a corpus constituted by the first hundred Cantigas de Santa Maria. It was possible to locate the stressed syllable in 92,93% of the found words.

Orthogonality relations and supercharacter formulas of U(m vertical bar n) representations

In this paper we obtain the orthogonality relations for the supergroup U(m|n), which are remarkably different from the ones for the U(N) case. We extend our results for ordinary representations, obtained some time ago, to the case of complex conjugated and mixed representations. Our results are expressed in terms of the Young tableaux notation for irreducible representations. We use the supersymmetric Harish-Chandra-Itzykson-Zuber integral and the character expansion technique as mathematical tools for deriving these relations. As a byproduct we also obtain closed expressions for the supercharacters and dimensions of some particular irreducible U(m|n) representations. A new way of labeling the U(m|n) irreducible representations in terms of m + n numbers is proposed. Finally, as a corollary of our results, new identities among the dimensions of the irreducible representations of the unitary group U(N) are presented. © 1997 American Institute of Physics.

O desafio de desenvolver artistas criativos no mundo das mídias digitais

From the second half of the twentieth century, with the proposal of working active listening, exploring sounds, the experience, the search for new forms of contemporary music notation, improvisation and experimental music composition, arise music educators Paynter Schafer and Koellreutter, known by the active method of second generation who contributed greatly to the development of creative processes in the classroom. Also arises, in the same period, the encounter between art and technology, expanding opportunities through digital media, open, participatory and interactive works such as Video art, Web art, Nanoarte and Locative Art, augmented, not only against the art with the public, through connections mediated by digital interfaces, providing new learning situations attractive for the development of creativity and artistic production as challenges in contemporary.

Accounting for uncertainty in ecological analysis: the strengths and limitations of hierarchical statistical modeling

Analyses of ecological data should account for the uncertainty in the process(es) that generated the data. However, accounting for these uncertainties is a difficult task, since ecology is known for its complexity. Measurement and/or process errors are often the only sources of uncertainty modeled when addressing complex ecological problems, yet analyses should also account for uncertainty in sampling design, in model specification, in parameters governing the specified model, and in initial and boundary conditions. Only then can we be confident in the scientific inferences and forecasts made from an analysis. Probability and statistics provide a framework that accounts for multiple sources of uncertainty. Given the complexities of ecological studies, the hierarchical statistical model is an invaluable tool. This approach is not new in ecology, and there are many examples (both Bayesian and non-Bayesian) in the literature illustrating the benefits of this approach. In this article, we provide a baseline for concepts, notation, and methods, from which discussion on hierarchical statistical modeling in ecology can proceed. We have also planted some seeds for discussion and tried to show where the practical difficulties lie. Our thesis is that hierarchical statistical modeling is a powerful way of approaching ecological analysis in the presence of inevitable but quantifiable uncertainties, even if practical issues sometimes require pragmatic compromises.

Interpolation estimate for a finite-element space with embedded discontinuities

We consider a recently proposed finite-element space that consists of piecewise affine functions with discontinuities across a smooth given interface Γ (a curve in two dimensions, a surface in three dimensions). Contrary to existing extended finite element methodologies, the space is a variant of the standard conforming Formula space that can be implemented element by element. Further, it neither introduces new unknowns nor deteriorates the sparsity structure. It is proved that, for u arbitrary in Formula, the interpolant Formula defined by this new space satisfies Graphic where h is the mesh size, Formula is the domain, Formula, Formula, Formula and standard notation has been adopted for the function spaces. This result proves the good approximation properties of the finite-element space as compared to any space consisting of functions that are continuous across Γ, which would yield an error in the Formula-norm of order Graphic. These properties make this space especially attractive for approximating the pressure in problems with surface tension or other immersed interfaces that lead to discontinuities in the pressure field. Furthermore, the result still holds for interfaces that end within the domain, as happens for example in cracked domains.

PERFORMANCE EVALUATION OF RESOURCE-AWARE BUSINESS PROCESSES USING STOCHASTIC AUTOMATA NETWORKS

In this work, we study the performance evaluation of resource-aware business process models. We define a new framework that allows the generation of analytical models for performance evaluation from business process models annotated with resource management information. This framework is composed of a new notation that allows the specification of resource management constraints and a method to convert a business process specification and its resource constraints into Stochastic Automata Networks (SANs). We show that the analysis of the generated SAN model provides several performance indices, such as average throughput of the system, average waiting time, average queues size, and utilization rate of resources. Using the BP2SAN tool - our implementation of the proposed framework - and a SAN solver (such as the PEPS tool) we show through a simple use-case how a business specialist with no skills in stochastic modeling can easily obtain performance indices that, in turn, can help to identify bottlenecks on the model, to perform workload characterization, to define the provisioning of resources, and to study other performance related aspects of the business process.
