Embedding knowledge in the design of an orthopaedic surgery learning
environment
This paper deals with an ongoing work involving surgeons, didacticians and computer
scientists. The objective is to design a computer based environment for learning screw
placement in orthopaedic surgery on the basis of a computer assisted surgical (CAS) tool. We
describe our methodology to create a didactical plug-in component for the CAS system. The
created system will consider the user's knowledge employed for the task to provide linked and
relevant feedback.
Cosmic Rhythm
Students write poems using rhyme and meter as they come to understand the mechanical concept of rhythm, based on the principle of oscillation, in a broader biological and cultural context, as seen in dance and sports, poetry and other literary forms, and communication in general. Note: The literacy activities for the Mechanics unit are based on physical themes that have broad application to our experience in the world — concepts of rhythm, balance, spin, gravity, levity, inertia, momentum, fri
Networked Learning, a relational approach weak and strong ties.
In this paper, we explore the idea of weak ties in networked learning. We go back to the original conception of
the strength of weak ties (Granovetter 1973) and relate this to a dialogic understanding of networked learning
(Koschmann 1999, Dysthe 2002). These theoretical ideas are applied to the examination of two networked
settings in which educational leaders exchange ideas and have the potential to create knowledge. We examine
these networks from the point of view of the overall pattern of in
It’s all In the Package
In this activity, students explore the concept of “reducing” solid waste and how it relates to product packaging and engineering advancements in packaging materials. Students read about and evaluate the highly publicized packaging decisions of two major U.S. corporations. They will evaluate different ways to package items in order to minimize the environmental impact, while considering issues such as cost, availability, product attractiveness, etc. Students will explore “hydrapulping” an
Computational Representation of Collaborative Learning Flow Patterns Using IMS Learning Desing
The identification and integration of reusable and customizable CSCL (Computer Supported Collaborative Learning) may benefit from the capture of best practices in collaborative learning structuring. The authors have proposed CLFPs (Collaborative Learning Flow Patterns) as a way of collecting these best practices. To facilitate the process of CLFPs by software systems, the paper proposes to specify these patterns using IMS Learning Design (IMS-LD). Thus, teachers without technical knowledge can p

Social Justice and Sustainability: arguments from political theory
Three distinguished political philosophers examine and discuss how theories of social justice and sustainability can be related to each other.
L’accompagnement des entreprises lorraines : Mécanismes fiscaux incitatifs
Les premières ”Rencontres lorraines de la propriété intellectuelle” tenues à Metz en mai 2008 avaient été consacrées à la propriété intellectuelle face au défi de la mondialisation.
L’édition 2009 de ces Rencontres, organisée le 6 octobre 2009 à Nancy, s’est concentrée sur la filière « fibres et éco-matériaux », laquelle, que ce soit à travers le bois, le textile, le papier, les composites ou encore les ma

Why are people attracted to conspiracy theories and why are those theories are so damaging? David Aaronovitch is an award-winning journalist, who has worked in radio, television and newspapers in the UK since the early 1980s. This event marks the launch of his new book Voodoo Histories: The Role of the Conspiracy Theory in Shaping Modern History.

The effect of collaborative knowledge modeling at a distance on performance and on learning
This study examines the effect of co-elaborating a knowledge model in dyads at a distance on performance and on learning. Forty-eight adults participated in the study. Participants were trained to re-represent knowledge taken from a text, using an object-typed knowledge modeling editor software tool. Knowledge modeling is similar to concept mapping, except that the former is based on a typology of knowledge objects and a typology of links, and that the structure of the knowledge representation i
4.5.1 The copolymer equation It can be shown that the rate of change of monomer concentration in any copolymerization is given by the equation where [M1] and [M2] are the concentrations of monomers 1 and 2 at any instant and r1
and r2., are reactivity ratios. The reactivity ratios represent the rate at which one type of gr
4.5 Copolymerization The alloying of metals to improve their properties is widespread and although many polymers used today are relatively pure (e.g. polystyrene, nylon), an increasing number are mixtures of two or more polymers. As with metals, one reason for doing this is to increase the range of properties. The major practical problem, however, is that homopolymers blend together with difficulty and even where blends are possible, as in some thermoplastics, phase separation can occur readily. This proble
4.4 Step growth polymerization 4.3.5 Co-ordination polymerization While most free radical and ionic polymerizations are carried out homogeneously, there is another important class of reaction which is often performed with solid catalysts. These reactions, discovered in the mid-fifties, have revolutionized polymer manufacture by permitting much less severe polymerization conditions than with other systems and by allowing a greater degree of control of polymer structure. Ziegler-Natta catalysts, as they are called, will convert vinyl and diene monomers 4.3.4 Ionic polymerization Free radicals are indiscriminate in the compounds they attack, and their non-selective nature in polymerization reactions leads to problems such as chain branching and transfer which affect the structure of the polymer produced. Anionic polymerization overcomes many of these problems. A typical commercial (but also see Box 8) anionic reaction is the polymerization of styrene using butyllithium, C4H9 4.3.3 Termination and transfer There are basically three ways in which chains terminate. The first is known as coupling and occurs when two free radicals join together. This can be represented by the general equation Such a mechanism significantly increases molecular mass, if it results in two polymer chains joining. This is the main mechanism which terminates the po
