Explication et préceptorat, à propos d'une étude de cas dans TéléCabri
Après avoir présenté un cadre d’étude des processus explicatifs, nous présentons l’analyse didactique d’une interaction téléprésente entre un précepteur humain et son élève. Nous montrons comment l’explication n’est pas une propriété intrinsèque du discours mais un attribut, résultat d’une construction de signification pendant l’interaction du précepteur avec son élève.
Academic Use of Digital Resources: Disciplinary Differences and the Issue of Progression
This paper examines the use of digital resources by academics in UK Higher education. The explosive growth of the Internet and in particular the Web has led to a growth in speculation about networked and e-learning (Steeples and Jones 2003, Brown and Duguid 2000). Increasingly researchers have become aware of the ways the university resists such changes and provides a 'resourceful constraint' to the changes surrounding the introduction of networked learning (Brown and Duguid 2000, Cornford 2002)
An Advanced E-learning Community Proposal Using MS Sharepoint Portal Server
In order to implement e-learning, quite often simple Internet technologies are used, usually without any clear pedagogical approach. Unfortunately this is not quite effective, it restricts learners' exchanges, while influence the quality of resulted knowledge construction. More sophisticated environments are needed when we vision e-learning as taken place in a rich and flexible Learning Community context, for young students or even for adults and professionals. Our proposal consists of an Electr

Charles E. Diehl Statue, Rhodes College, Memphis, Tennessee
Color postcard with divided back,This statue by Edwin Rust is of Charles E. Diehl who was president of the College from 1917 until 1948. It is 9 feet tall and in bronze. It was sculpted by Edwin Rust and stands in front the Burrow Building at Rhodes College.
Interview with Professor Christoph von Fürer-Haimendorf
Professor Christoph von Fürer-Haimendorf was one of the grandfathers of Himalayan anthropology. Alan Macfarlane, one of his last PhD students at the School of Oriental and African Studies and now himself Professor of Anthropological Science at the Univesity of Cambridge, interviewed Christoph von Fürer-Haimendorf in his house in Lode, near Cambridge, in June 1983. The interview was filmed on Sony U-Matic, a large format video tape, which is now obsolete but which has been digitised to DVCam, a
Novel associated PVA/PVP hydrogels for nucleus pulposus replacement
Degenerative disc disease in the lumbar spine is marked by a dehydration of theintervertebral disc and loss of biomechanical function of the spinal unit. Since thecurrent surgical procedures are ineffective in restoring natural biomechanical functionback to the diseased disc, researchers have looked to replace the intervertebral disc.These designs are flawed in that they either donâ t restore natural movement back to thespinal unit, require surgeries that are highly invasive, or they further p
Scaling relations from scale model experiments on equilibrium accretionary beach profiles
Movable bed, scale model experiments were conducted at three length scales, 1/8.5, 1/10 and 1/11, in a 90 ft-long wave tank to study scale effect and equilibrium profile characteristics under sinusoidal, accreting wave action. Geometric similarity, deep water wave steepness, wave Froude number, densimetric Froude number, and particle Reynolds number were preserved by selecting the same sediment and fluid in the model and prototype. Wave height was measured with parallel-wire resistance gauges wh
Novel organic-inorganic hybrid mesoporous materials and nanocomposites
Organic-inorganic hybrid mesoporous materials have been prepared successfully via the nonsurfactant templated sol-gel pathway using dibenzoyl-L-tartaric acid (DBTA) as the templating compound. Styrene and methyl methacrylate polymers have been incorporated into the mesoporous silica matrix on the molecular level. The synthetic conditions have been systematically studied and optimized. Titania based mesoporous materials have also been made using nonionic polyethylene glycol surfactant as the pore
In-vitro tiered approach alternative to live animal testing for determination of ocular or dermal ir
There is a continual need for information concerning the potential for chemicals, if inadvertently splashed into the eyes, to cause effects from irritation to total blindness. This information is currently generated by exposing the eyes of live rabbits to the chemical. As can be imagined, this often results in severe distress to the animal while generating information that we have shown to be discernable without putting any animals at risk. This may be accomplished by replacing the live animal t
Comprehension of emotion in neurodegenerative disorders
Recent evidence indicates that the posterior corpus callosum is smaller in patients with Alzheimer's disease (AD). Conversely, it has been demonstrated that patients with frontal systems deficits also have degradation of the anterior corpus callosum. Although these investigations indicate possible morphological relationships between the corpus callosum and cortical structures in neurodegenerative disorders, the relationship between specific neuropsychological measure of cognitive functioning and
Reconfigurable control of Aircraft undergoing Sensor and Actuator Failure
Significant number of fatal aircraft accidents in recent years have been linked to component failures. With the predicted increase in air traffic these numbers are likely to increase. With reduction of fatal accidents as motivation, this dissertation investigates design of fault tolerant control systems for aircrafts undergoing sensor and/or actuator failures. Given that the nominal controller may perform inadequately in the event of sensors and/or actuator failure, the feasible approach for suc
The United States Postal Service: A Case Study of Large Scale Government Transformation
The challenge of replacing the baby-boomer generation of employees is beginning in government agencies as they face a “tsunami” of retirements. This generation forms the core of middle managers or supervisors who are essential to providing the continuity in government organizations that serve the needs of citizens on a daily basis, or most critically in times of crisis.
This same generation of government employees worked through decades of change in public administration. The 1980s privat

Overlapping worlds: an examination of macroregional archaeology
Archaeologists have long recognized the fact that long distance relationships existed in prehistoric societies. There have been many efforts to develop models for a satisfactory explanation for interactions and social change among groups. World Systems Theory, developed by Immanuel Wallerstein, is one such effort to examine mechanisms of inter-societal relationships and a determination of units of analysis for Pre-Columbian societies. To utilize this theory, archaeologists have made modification
Evaluation of springback prediction capability using uniform pure bending
The aim of this study is to develop uniform pure bending as an objective test for determining the accuracy of springback prediction by employing different FEA techniques. A complete theoretical solution for the bending moment and change in sheet thickness is available only for uniform pure bending of perfectly plastic sheets. However, plastic hinging develops naturally in simulations of bending perfectly plastic sheets. We have developed a method to prevent plastic hinging and achieve uniform pu
Providing for the Buddha: monastic centres in Eastern India (audio)
This paper attempts to address one of the issues of the series, viz. patronage, not just the relationship between Buddhist monastic centres and kings, but more significantly the lay community and its continuing support of monks and nuns and sponsorship of ritual activities, as well as maintenance of monastic structures. Eastern India is here defined as the state of Orissa, but includes contiguous coastal regions. The time period covered ranges from the 4th-3rd centuries BC when the earliest
