Traditional negotiation, conducted face-to-face and via mail or telephone, is often difficult to manage, prone to misunderstanding, and time consuming. Automated negotiation promises a higher level of process efficiency, and more importantly, a faster emergence and a higher quality of agreements. The potential monetary impact has led to an increasing demand for systems composed of software agen...

The emergence of computer and multimedia technology change the forms of instructional materials and instructional design plays an important role on student learning outcome in multimedia learning. Research has found that using advance organizers has the potential for achieving learning objectives. Thus, this study investigated how using different forms (oral narration/onscreen text) of advance ...

The paper provides an explanation for altruistic behavior based on the matching and learning technology in the population. In a in®nite structured population, in which individuals meet and interact with their neighbors, individuals learn by imitating their more successful neighbors. We ask which strategies are robust against invasion of mutants: A strategy is unbeatable if when all play it and ...

It is well known that food stress resulting from density-dependent factors affects the mutation rate and hence promotes diversity. It is also known that in bacterial cultures the quality and composition of the growing media conditions the emergence of different spatial patterns. We would like to address the following question: how will the different spatial regions with well defined geometrical...

In this multi-method study, we investigated the strategies used by members who emerged as leaders in organizations communicating primarily via e-mail communication. We hypothesized and found that members who emerged as leaders tended to rely on soft influence tactics, were consistent in their usage of a certain influence tactic, and participated in e-mail exchanges more than other members. Addi...

seedling characteristics of different sunflower (helianthus annus l.) cultivars under drought stress and inoculation with the azospirillum lipoferum in a spilt-factorial layout based on randomized complete block design with three replications were evaluated. treatments included dehydration stress (seed produced on maternal plants which irrigated after 60 (desirable irrigation), 120 (medium stre...

Results from initial experiments in western Nebraska suggest that opportunity exists to decrease seeding rates of pea (Pisum sativum L.) optimize yield while maintaining partial net return. Refined planting recommendations, especially time, are still largely unknown for Nebraska. This experiment evaluated the effects and dates on emergence, grain yield, components. Two locations were 2018 2019....

We study a general predator–prey system in a spatially heterogeneous environment. The predation process, which occurs on a behavioural time-scale, is much faster than the other processes (reproduction, natural mortality and migrations) occurring on the population dynamics time-scale. We show that, taking account of this difference in time-scales, and assuming that the prey have a refuge, the dy...
