Web-based distance learning provides a flexible environment for students, but there is a lack of interaction between students and the instructor. To overcome this drawback, we propose a systematic assessment mechanism to enhance interaction between both sides and to maximize student learning performance. This mechanism is presented by means of a new courseware diagrams, which combines useful to...

Motivated by a desire to extend the Social Influence Model of Technology Use, this paper empirically examines the impact of normative social influence on group media preference patterns and group meeting outcomes in a setting where established groups voluntarily used various communication media over a three-month software development project period. The overall results suggest that conformity t...

This paper presents a pedagogical agent designed to support students in an embodied, discovery-based learning environment. Discovery-based learning guides students through a set of activities designed to foster particular insights. In this case, the animated agent explains how to use the Mathematical Imagery Trainer for Proportionality, provides performance feedback, leads students to have diff...

American college students’ and children’s scores on two measures of the need for social approval closely follow changes in the state of the larger society, decreasing signiWcantly from 1958 to 1980 and leveling oV between 1980 and 2001 (total nD 36,004 across 203 samples of college students responding to the Marlowe–Crowne Social Desirability scale; total nD 4741 across 38 samples of children r...

This document defines new Dynamic Host Configuration Protocol (DHCPv4 and DHCPv6) options that contain a list of IP addresses and a list of domain names that can be mapped to servers providing IEEE 802.21 type of Mobility Service (MoS) (see RFC 5677). These Mobility Services are used to assist a mobile node (MN) in handover preparation (network discovery) and handover decision (network selectio...

This paper deals with the representation and solution of asymmetric Bayesian decision problems. We present a formal framework, termed asymmetric influence diagrams, that is based on the influence diagram and al­ lows an efficient representation of asymmet­ ric decision problems. As opposed to exist­ ing frameworks, the asymmetric influence di­ agram primarily encodes asymmetry at the qualitativ...

conclusions the findings of this review showed that many factors can influence the body image of women suffering from breast cancer. these factors were predictors of patients’ inter-personal and intra-personal relationships with their partners and others who influenced various other aspects of their lives, possibly leading to many life’s issues. these factors must be identified and considered t...

according to its superficial anatomical location, the thyroid gland is easily accessible by sonography. sonography allows an exact documentation of the size and thyroid volume. the relationship between thyroid volume and anthropometric characteristics is a matter of controversy. the aim of this study was to investigate thyroid volume and its determinants in healthy adult. a cross-sectional stud...

Even though the interaction of intrinsic motivation and concerns for social approval has important implications both for crowding out of intrinsic motivation through incentives and for producer choices, little is known about this interaction empirically. We present a laboratory experiment that provides evidence of a relevant interaction effect in the context of ethical consumption. We elicit a ...
