This study examined the antecedents and outcomes of interaction in asynchronous online learning courses. The research model was tested by using a Partial Least Squares analysis on the survey data. A total of 397 valid unduplicated responses from students who have completed at least one online course at a university in the Midwest were used to examine the structural model. All hypotheses except ...

This paper presents an approach based on cooperative selforganization for arti cial systems, in order to tackle openness and dynamics. We propose to use cooperation as a local criterion enabling parts of the system the cooperative agents to reorganize as to modify their interactions and then the global function. We underline the di culty of de ning cooperation and the means to reestablish a coo...

A distributed constraint satisfaction problem can formalize various application problems in MAS, and several algorithms for solving this problem have been developed. One limitation of these algorithms is that they assume each agent has only one local variable. Although simple modifications enable these algorithms to handle multiple local variables, obtained algorithms are neither efficient nor ...

this study investigates the relationship between meaningfulness of life and hope, happiness, depression and life satisfaction. participants consist of 382 women who work in schools and other educational organizations in shiraz. the techniques used include life regard index (lri), depression- happiness scale (dhs), satisfaction with life scale (swls), and adults dispositional hope scale (adhs). ...

The feature recognition problem is formulated as a geometric constraint satisfaction problem (GCSP), in which variables are the faces in the delta volume, the possible feature classiications determine values for the variables, and the constraints are the geometric and topological properties between the variables. A novel representation language is proposed to encode more, and somewhat redundant...

This paper presents a constraint-based methodology for product design with advanced virtual reality technologies. A hierarchically structured and constraintbased data model is developed to support product design from features to parts and further to assemblies in a VR environment. Product design in the VR environment is performed in an intuitive manner through precise constraint-based manipulat...

Several variants of the Constraint Satisfaction Problem have been proposed and investigated in the literature for modelling those scenarios where solutions are associated with some given costs. Within these frameworks computing an optimal solution is an NP-hard problem in general; yet, when restricted over classes of instances whose constraint interactions can be modelled via (nearly-)acyclic g...

This study analyzed patients’ perceptions of their nurses’ willingness to engage in interaction and patients’ satisfaction in communication about health with their nurses (N = 270). Results indicated that a strong and significant positive correlation exists between patients’ perceptions of their nurse’s interaction engagement and their satisfaction with their relationship with their nurse (r = ...

This study analyzed patients’ perceptions of their physicians’ willingness to engage in interaction and be open, and patients’ satisfaction in communication about health with their physicians (N=322). Results indicated that a moderate to strong and significant positive correlation exists between patients’ perceptions of their physician’s interaction involvement and their satisfaction with their...

In this study, the authors proposed and tested a 3-way interaction among positive affectivity (PA), job satisfaction, and tenure in predicting negative employee outcomes. Specifically, the authors predicted that the relationship between job satisfaction and negative outcomes would be stronger for high PAs and that this relationship would be more pronounced for longer tenured employees. Results ...
