âThe International Teacher Leadership project,â a case of international action research.
Copyright CARNThe paper arises from the International Teacher Leadership project, a research and development project involving researchers and practitioners in 14 European countries. The paper provides a conceptual exploration of the idea of teacher leadership and its role in educational reform, central to which is the idea that teachers, regardless of their level of power and organisational position, can engage in the leadership of enquiry-based development activity aimed at influencing their colleagues and embedding improved practices in their schools. The paper provides an outline of the projectâs methodology which builds on that used in the Carpe Vitam Leadership for Learning project (Frost, 2008a). It is a form of collaborative
action research which is highly developmental and discursive. It seeks to identify principles, strategies and tools that can be applied in a range of cultural settings. The paper includes a thematic analysis of the cultural contexts and policy environments of the participating countries in order to identify the obstacles to teacher leadership and to inform the nature of the support strategies employed

The benefits of long range ultrasonic sensors for the efficient InLine inspection and corrosion monitoring of previously Non-piggable or hard to reach pipelines
One third of all pipelines worldwide are considered un-piggable by the widely used existing Smart pigs. The vast majority of buried oil pipelines in Europe carry hazardous fluids at high pressure and temperature. While the most common type of InLine Inspection (ILI) pigs use magnetic flux leakage (MFL) techniques. Several limitations of this approach have been identified such as its effectiveness in distinguishing acceptable anomalies from defects, or determining whether the indication is on the external surface or internal as well as the signal reading when the pipe is encased by steel conduits, which is often the case through road and rail crossings. The other common technique used for the purpose is that of Ultrasonic inspection pigs. In this case the process of covering the whole pipeline length with Ultrasonic scan inspection would be both exhaustively time-consuming as well as impractical in sheer data volume to analyse and interpret even at the age of the IOT. iPIM research program is bringing the idea of using Long Range Ultrasonic Guided Waves for a pigging system that is a permanent, reliable, manageable and energy efficient solution to pipeline monitoring. A permanent network of novel low profile Long Range Ultrasonic (LRU) sensors will incorporate on-board signal processing capabilities
3D multi-agent models for protein release from PLGA spherical particles with complex inner morphologies
In order to better understand and predict the release of proteins from bioerodible micro- or nanospheres, it is important to know the influences of different initial factors on the release mechanisms. Often though it is difficult to assess what exactly is at the origin of a certain dissolution profile. We propose here a new class of fine-grained multi-agent models built to incorporate
increasing complexity, permitting the exploration of the role of different parameters, especially that of the internal morphology of the spheres, in the exhibited release profile. This approach, based on Monte-Carlo (MC) and Cellular Automata (CA) techniques, has permitted the testing of various assumptions and hypotheses about several experimental systems of nanospheres encapsulating proteins. Results have confirmed that this modelling approach
has increased the resolution over the complexity involved, opening promising perspectives for future developments, especially complementing in vitro experimentation
A duality of generalized metric spaces
AbstractWe develop a duality theory for LawvereÊŒs generalized metric spaces that extends the Lawson duality for continuous dcpos and open filter reflecting maps: we prove that the category of relatively cocomplete and continuous [0,â]-categories considered with open filter reflecting maps is self-dual
Modeling outcomes of soccer matches
We compare various extensions of the BradleyâTerry model and a hierarchical Poisson log-linear model in terms of their performance in predicting the outcome of soccer matches (win, draw, or loss). The parameters of the BradleyâTerry extensions are estimated by maximizing the log-likelihood, or an appropriately penalized version of it, while the posterior densities of the parameters of the hierarchical Poisson log-linear model are approximated using integrated nested Laplace approximations. The prediction performance of the various modeling approaches is assessed using a novel, context-specific framework for temporal validation that is found to deliver accurate estimates of the test error. The direct modeling of outcomes via the various BradleyâTerry extensions and the modeling of match scores using the hierarchical Poisson log-linear model demonstrate similar behavior in terms of predictive performance
