Dialogkonferansen – arena for kollektiv utvikling i skolen

The purpose of this chapter is to examine dialogue conference as a space for collective school improvement. The article employs the theory of action research in general and the methodology of dialogue conferences in particular as lenses to explore and discuss challenges in using dialogue conferences as tools for school improvement. Two examples from different action research studies using dialogue conference show different ways of doing the conferences with the aim of improving educational practices. Findings from these studies suggest that we need to find new ways to handle the representative problem in action research projects in networks. That is when we use groups from schools as participants in action research studies as opposed to full participation. Findings also show there might be challenges for schools to export ideas from the dialogue conference to the practice in classrooms. This problem relates to a possible distance between the discursive arena and educational practice. The article also concludes that we need to use different kinds of dialogue conferences, depending on what intentions and aims for school improvement we are looking for.

POLIMEDIA: UNA VÍA PARA LA DIFUSIÓN DEL LENGUAJE MUSICAL

RESUMEN La investigación tiene como objetivo desarrollar polimedias para la cátedra de Lenguaje Musical en el nivel básico medio de educación en Ecuador. El trabajo investigativo evidencia como problema más representativo que la asignatura no cuenta con suficientes recursos didácticos sin recibir la influencia de nuevas técnicas y la aplicación de la tecnología. Se utilizó métodos que sustenten los elementos teóricos y las herramientas tecnológicas más idóneas en la preparación de la polimedia acorde al tipo de temática educativa; así como, la herramienta SocialBlade para medir y evaluar las polimedias del canal en YouTube. Entre los resultados se encuentra el procedimiento para crear una polimedia y la difusión del contenido en un canal de video en YouTube y la medición cuantitativa del número de visualizaciones, me gusta y no me gusta de las polimedias subidas al canal social; reflejándose la importancia de utilizar recursos tecnológicos en el proceso de enseñanza – aprendizaje. PALABRAS CLAVE: audiovisual; lenguaje musical; polimedia; videos educativos. POLIMEDIA: A WAY FOR THE DIFFUSION OF MUSICAL LANGUAGE ABSTRACT The objective of the research is to develop polimedias for the Chair of Musical Language at the basic level of education in Ecuador. The investigative work shows as a more representative problem that the subject does not have enough didactic resources without being influenced by new techniques and the application of technology. We used methods that support the theoretical elements and the most suitable technological tools in the preparation of the polimedia according to the type of educational theme; as well as, the tool SocialBlade to measure and evaluate the polimedias of the channel on YouTube. Among the results is the process to create a polimedia and the diffusion of the content in a YouTube video channel and its subsequent measurement.

Application Integration within the Enterprise Context

The application software life cycle considers the functionality of a given collection of components within the context of a consumer’s requirements definition. One set of requirements that are frequently overlooked are the requirements for application integration within the context of the enterprise environment. If an application creates vulnerabilities for other applications, is an administrative nightmare to maintain, or does not consider the security context required for execution; the application may not fulfill the intended requirements. This chapter addresses the question of the consideration of the enterprise information system’s administrative and execution context as a component of the application software development process. The potential impact these considerations have on the acceptance of an application by the application’s user community is presented, with illustrations of some representative problem areas for the reader’s consideration.

Stability of a Time-Delayed System With Parametric Excitation

This paper investigates two different temporal finite element techniques, a multiple element (h-version) and single element (p-version) method, to analyze the stability of a system with a time-periodic coefficient and a time delay. The representative problem, known as the delayed damped Mathieu equation, is chosen to illustrate the combined effect of a time delay and parametric excitation on stability. A discrete linear map is obtained by approximating the exact solution with a series expansion of orthogonal polynomials constrained at intermittent nodes. Characteristic multipliers of the map are used to determine the unstable parameter domains. Additionally, the described analysis provides a new approach to extract the Floquet transition matrix of time periodic systems without a delay.

NUMERICAL ANALYSIS OF SOME DECOUPLING TECHNIQUES FOR THE APPROXIMATION OF THE UNSTEADY FLUID STRUCTURE INTERACTION

This paper deals with the numerical analysis of some algorithms for the simulation of the interaction between a fluid and a structure in the case where the deformation of the structure induces an evolution in the fluid domain. This is a highly nonlinear problem and the algorithms of time decoupling are very numerous and not completely well understood. We study three of them for a one-dimensional representative problem. We prove that the considered algorithms are stable and we also prove that one of them is convergent.

The Use of Neural Networks and Genetic Algorithms for Design of Groundwater Remediation Schemes

The increasing incidence of groundwater pollution has led to recognition of a need to develop objective techniques for designing reniediation schemes. This paper outlines one such possibility for determining how many abstraction/injection wells are required, where they should be located etc., having regard to minimising the overall cost. To that end, an artificial neural network is used in association with a 2-D or 3-D groundwater simulation model to determine the performance of different combinations of abstraction/injection wells. Thereafter, a genetic algorithm is used to identify which of these combinations offers the least-cost solution to achieve the prescribed residual levels of pollutant within whatever timescale is specified. The resultant hybrid algorithm has been shown to be effective for a simplified but nevertheless representative problem; based on the results presented, it is expected the methodology developed will be equally applicable to large-scale, real-world situations.

Numerical Simulation of Transient Finite Deformations of Thin Beams

The formulation of the problem of finite elastic-viscoplastic deformation of thin beams is described. The finite element analysis of a representative problem is presented and various solution methods are surveyed.
