The menu-dependent nature of regret-minimization creates subtleties in applying regret-minimization to dynamic decision problems. Firstly, it is not clear whether forgone opportunities should be included in the menu. We explain commonly observed behavioral patterns as minimizing regret when forgone opportunities are present, and also show how the treatment of forgone opportunities affects behav...

In scenarios where a set of independent business partners engage in complex conversations, global interaction models are a means to specify the allowed interaction behavior from a global perspective. In these models atomic interactions serve as basic building blocks and behavioral dependencies are defined between them. Global interaction models might not be locally enforceable, i.e. they specif...

We present a system for testing turn-taking strategies in a simulation environment, in which artificial dialogue participants exchange audio streams in real time – unlike earlier turn-taking simulations, which interchanged unambiguous symbolic messages. Dialogue participants autonomously determine their turn-taking behaviour, based on their analysis of the incoming audio. We use machine-learnin...

Learning in the laboratory is a discovery process where students learn by physically manipulating the laboratory apparatus and collaborating with team members. However, the development of new information technology makes new types of labs available but also presents a paradox. Advocates and detractors of different lab modalities can be found. A full-text review of sixty articles indicates that ...

We are interested in how the posters in the hacker community contribute and exchange information. Text-mining techniques have been used to learn about the quality nature of the posts. We found that the knowledge exchanges in the hacker community are both interesting and complex. We uncover some interesting knowledge exchange behavioral patterns between initial post contributor and post repliers...

Human life is based on social interactions. These interactions are dictated by the attitudes and beliefs people have. Personal attitudes and beliefs are not constant over time but are influenced on an individual level. The interactions with friends, coworkers and others can influence one?s opinion. Such an attitude change can occur during discussions. It is hypothesised that these changes are s...

Knowing the locations and spatio-temporal paths of individual mice is an essential prerequisite for behavioral analysis of large groups of laboratory mice. Traditional observations have been carried out by trained humans who are able to distinguish more than fifty behavioral patterns. This is a tedious labor limited with respect to observation length. In this paper we propose a tracking solutio...

Up until now, most approaches to Online Dispute Resolution focused on "traditional" problems such as the generation of solutions, the support to negotiation or the definition of strategies. Although these problems are evidently valid and important ones, research should also start to consider new potential issues that arise from technological evolution. In this paper we analyse the new challenge...

Project-based learning using online learning environments is becoming increasingly popular. To in-depth explore the behavioural patterns and limitations faced by students in project-based learning where online forums are used. This study conducted an empirical case study of an online project-based learning activity in a management course, in which 70 college students participated. The study int...

The aggressive online solicitation of youth by online sexual predators has been established as an unintended consequence of the connectedness afforded individuals through social media. Computer science research that has focused on the detection of online sexual predators is scant and absent behavioral theory. We address this gap through examining what behavioral patterns emerge regarding how on...
