This work is the first systematic investigation of initiative in human-human tutorial dialogue. We studied initiative management in two dialogue strategies: didactic tutoring and Socratic tutoring. We hypothesized that didactic tutoring would be mostly tutor-initiative while Socratic tutoring would be mixedinitiative, and that more student initiative would lead to more learning (i.e., task succ...

This communication describes the theoretical and practical tools that permit the automatic construction of a verbal lexicon in view of a didactic utilisation by linguists and an automatic treatment of written texts. Firstly we present the taken theoretical choices for the representation of the verbal polysemy in view of a practical utilisation; and secondly we present some elements of a semi-au...

This paper discusses the feasibility and effectiveness of using vectors of the current dipoles representing local electric activity inside the atrial myocardium during atrial fibrillation. The application relates to the search for improving the performance of electric signals observed on the body surface in the diagnoses of this life-threatening arrhythmia. The topics addressed include some his...

Families of 54 behaviorally disturbed preschool-aged children (3 to 5 years) were randomly assigned to 1 of 3 treatment conditions: standard parent-child interaction therapy (PCIT; STD); modified PCIT that used didactic videotapes, telephone consultations, and face-to-face sessions to abbreviate treatment; and a no-treatment waitlist control group (WL). Twenty-one nondisturbed preschoolers were...

This will enable an evaluation of the Return On Investment (ROI) using the new concept of Yield Index “e-lYI” (e-learning Yield Index), introduced in this study. The Yield Index “e-lYI” suggests an original way to evaluate the implementation of e-learning methodologies into campus based environments; still, the new index will help professionals involved in the management of the transition from ...

While the effectiveness of one-on-one human tutoring has been well established, a great deal of controversy surrounds the issue of which features of tutorial dialogue separate effective uses of dialogue in tutoring from those that are less effective. In this paper we present a formal comparison of Socratic versus Didactic style tutoring that argues in favor of the Socratic tutoring style.

This study evaluated physical education knowledge according to gender, secondary school programme, year of study and type of knowledge. The results of multivariate analysis of variance show that the programme of study had the highest impact (20.2% of the variance) on both dependent variables (conceptual and specific knowledge), the impact of gender was about half as high (11.7% of the variance)...

A health record database contains structured data fields that identify the patient, such as patient ID, patient name, e-mail and phone number. These data are fairly easy to de-identify, that is, replace with other identifiers. However, these data also occur in fields with doctors' free-text notes written in an abbreviated style that cannot be analyzed grammatically. If we replace a word that lo...
