Estimating the prerequisite structure of skills is a crucial issue in domain modeling. Students usually learn skills in sequence since the preliminary skills need to be learned prior to the complex skills. The prerequisite relations between skills underlie the design of learning sequence and adaptation strategies for tutoring systems. The prerequisite structures of skills are usually studied by...

Domestic dogs are unusually skilled at reading human social and communicative behavior--even more so than our nearest primate relatives. For example, they use human social and communicative behavior (e.g. a pointing gesture) to find hidden food, and they know what the human can and cannot see in various situations. Recent comparisons between canid species suggest that these unusual social skill...

Human development and economic development are intrinsically linked. Guided by human capital theory, economists are increasingly recognizing the importance of a range of other skills – in addition to intelligence and technical skills – for economic success. Until fairly recently, years of education completed, literacy, numeracy and IQ – often used as proxies for cognitive ability – were the mai...

This paper presents a general approach to the acquisition of sensor-based robot skills from human demonstrations. Since human-generated examples cannot be assumed to be optimal with respect to the robot, adaptation of the initially acquired skill is explicitly considered. Results for acquiring and reening manipulation skills for a Puma 260 manipulator are given.

When established communication systems cannot be used, people rapidly create novel systems to modify the mental state of another agent according to their intentions. However, there are dramatic inter-individual differences in the implementation of this human competence for communicative innovation. Here we characterize psychological sources of inter-individual variability in the ability to buil...

Communication skills tend to decline with time unless they are regularly recalled and practiced. However, most medical schools still deliver clinical communication training only during pre-clinical years although the clinical environment is considered to be ideal for acquiring and teaching clinical communication. The aim of this article is to review the barriers that prevent communication skill...

in postpartum departments the skills and experience of doctors and midwives will overlap together but it is not sufficiently recognized . little importance to the ability of midwives will reduce the scope of their responsibilities and decision-making power will be taken from them , also this will result in demoralization and decreasing job satisfaction. in this situation work load of new physic...
