OBJECTIVE Existing reports suggest that males significantly outperform females in navigating 3-D virtual environments. Although researchers have recognized that this may be attributable to males and females possessing different spatial abilities, most work has attempted to reduce the gender gap by providing more training for females. In this paper, we explore using large displays to narrow the ...

O n-line literature searches of bibliographic databases such as PubMed (www.ncbi.nlm.nih.gov/entrez/query.fcgi) are now integral to the lives of clinicians. A huge amount of knowledge can be gleaned from even a basic PubMed search, while the use of advanced functions can add speed and focus. The 11 million or so abstracts that constitute PubMed undoubtedly make it one of the most significant ba...

We present a literature review that identifies a gap in business intelligence knowledge regarding the fit between technology and the tasks solved using the technology. We propose a model that frames the fit between task characteristics and the use of business intelligence. The model represents task, system, and information quality as independent constructs with task compatibility as the depende...

In this paper we present our advances in a data structure, the Gap Navigation Tree (GNT), useful for solving different visibility-based robotic tasks in unknown planar environments. We present its use for optimal robot navigation in simply-connected environments, locally optimal navigation in multiply-connected environments, pursuit-evasion, and robot localization. The guiding philosophy of thi...

In the past few years, volunteers have produced geographic information of different kinds, using a variety of different crowdsourcing platforms, within a broad range of contexts. However, there is still a lack of clarity about the specific types of tasks that volunteers can perform for deriving geographic information from remotely sensed imagery, and how the quality of the produced information ...

Gap and overlap tasks are widely used to promote automatic versus controlled saccades. This study examines the hypothesis that the right posterior parietal cortex (PPC) is differently involved in the two tasks. Twelve healthy students participated in the experiment. We used double-pulse transcranial magnetic stimulation (dTMS) on the right PPC, the first pulse delivered at the target onset and ...

temporomandibular joint ankylosis causes limitation in mouth opening and establishes severe deformity and asymmetry in patient’s face, especially in children. surgery is the only treatment. this study was conducted to compare the effect of two surgical approaches, gap arthropasty and interpositional gap arthroplasty, on rate of maximum interincisal opening in temporomandibular joint ankylosis. ...

Throughout the history of human being, the generations' inter-relations were of special concern. The social sciences researchers have always  tried to introduce the changing patterns of relations between the elder and the youth groups, they  presented two consensus and conflict  theories regarding different historical periods. One important matter in humans' life is always communication. Young ...

The design and evaluation of most current information visualization systems descend from an emphasis on a user’s ability to “unpack” the representations of data of interest and operate on them independently. Too often, successful decision-making and analysis are more a matter of serendipity and user experience than of intentional design and specific support for such tasks; although humans have ...
