Recent studies show that humans engage in multitasking information behaviors, often in libraries, as they seek and search for information on more than one information task. Multitasking information behaviors may consist of library search and use behaviors, or database or Web search sessions on multiple information tasks. However, few human information behavior models of seeking, searching or us...

These studies are part of a project aiming to reveal relevant aspects of human-dog interactions, which could serve as a model to design successful human-robot interactions. Presently there are no successfully commercialized assistance robots, however, assistance dogs work efficiently as partners for persons with disabilities. In Study 1, we analyzed the cooperation of 32 assistance dog-owner dy...

While it is universally acknowledged that both bottom up and top down factors contribute to allocation of gaze, we currently have limited understanding of how top-down factors determine gaze choices in the context of ongoing natural behavior. One purely top-down model by Sprague, Ballard, and Robinson (2007) suggests that natural behaviors can be understood in terms of simple component behavior...

The primary purpose of this research paper is to present an empirical study framed by the theory that task-oriented and relations-oriented leadership behaviors are positively related to the employees’ perceptions of organizational climate. The study examined the following research question: Are task-oriented and relations-oriented leadership behaviors related to different dimensions of organiza...

We developed a system learning behaviors represented as sets of fuzzy rules for autonomous agents. In the past, we adopted our approach to learn successfully simple reactive behaviors, also in those cases when the evaluation function used in our reinforcement learning schema judges unevenly the different situations the autonomous agents operate on. In this paper we present a new version of our ...

| New reactive behaviors that implement formations in multi-robot teams are presented and evaluated. The formation behaviors are integrated with other navi-gational behaviors to enable a robotic team to reach nav-igational goals, avoid hazards and simultaneously remain in formation. The behaviors are implemented in simulation , on robots in the laboratory and aboard DARPA's HMMWV-based Unmanned...

This paper discusses the difficulties of analyzing and synthesizing intelligent collective behaviors for a collection of mobile robots. It reviews available approaches and presents a bottom-up experimental alternative consisting of a set of robust global behaviors based on simple local rules. These basic behaviors are designed to be sufficient and additive, in order to be combined into more com...

ITS authoring frameworks are useful to reduce the efforts needed to create tutors, but the resulting tutors are usually more limited than domainspecific ones. The sophistication of the pedagogical behaviors they can produce depends on the knowledge components available to model a task domain. In this paper, we present research focused on integrating sophisticated domainindependent pedagogical b...

The computational representation and classification of behaviors is a task of growing interest in the field of Behavior Informatics, being series of data a common way of describing those behaviors. However, as these data are often imperfect, new representation models are required in order to effectively handle imperfection in this context. This work presents a new approach, Frequent Correlated ...

Employee commitment is an indispensible cog in an organization's growth and motivation influences talent to drive this growth. Employees exhibit certain behaviors by going beyond the normal call of duty. These behaviors are called Organizational Citizenship Behaviors (OCB) and they contribute significantly to an organization's growth. Job characteristics like Skill Variety, Task Identity, Task ...
