Three studies of collaborative activity were conducted as part of research in developing multimedia technology to support collaboration. One study surveyed users’ opinions of their use of video conference rooms. Users indicated that the availability of the video conference rooms was too limited, audio quality needed improvement, and a shared drawing space was needed. A second study analyzed vid...

BACKGROUND The objective of this study was to develop and assess the reliability of a modified scoring system for evaluating the function of the two pelvic limbs separately, in ambulatory thoracolumbar myelopathy dogs. A previously established neurologic score scale for dogs with T3-L3 lesions was modified in order to provide a separate score for each pelvic limb. RESULTS Seventeen ambulatory...

BACKGROUND Co-occurring disorders present a challenge for providers who often fail to diagnose them with accuracy. This study explores the assessment process of co-occurring depressive and substance use disorders in community health clinics serving ethnically diverse patients. The goals are to identify how symptoms discussed in intake, as well as patient and provider characteristics, are associ...

The purpose of this study was to explore the use of cognitive task analysis to inform the teaching of psychomotor skills and cognitive strategies in clinical tasks in dental education. Methods used were observing and videotaping an expert at one dental school thinking aloud while performing a specific preclinical task (in a simulated environment), interviewing the expert to probe deeper into hi...

Using a referent detection paradigm, we examined whether listeners can determine the object speakers are referring to by using the temporal alignment between the motion speakers impose on objects and their labeling utterances. Stimuli were created by videotaping speakers labeling a novel creature. Without being explicitly instructed to do so, speakers moved the creature during labeling. Traject...

Aggression is an innate behavior that has likely evolved in the framework of defending or obtaining resources. This complex social behavior is influenced by genetic, hormonal, and environmental factors. In many organisms, aggression is critical to survival, but the ability to control and suppress aggression in distinct contexts also is necessary. Invertebrate organisms, with their relatively si...

BACKGROUND Tics are involuntary, brief, stereotyped motor and vocal behaviors often associated with irresistible urges. They are a defining symptom of the classic neuropsychiatric disorder, Tourette syndrome (TS), and constitute an example of disordered human volition. The neural correlates of tics are not well understood and have not been imaged selectively. METHODS Event-related [(15)O]H(2)...

Purpose Fatigue is an important problem in children receiving intensive chemotherapy and hematopoietic stem cell transplantation (HSCT). Exercise may be an effective intervention for fatigue. Individualized yoga represents an ideal intervention because it can be tailored according to an individual child's needs. Little is known about how to structure a standardized yoga program for intensivelyt...

During swallowing, airway protection is achieved in part by laryngeal elevation. Although multiple muscles are normally active during laryngeal elevation, neuromuscular stimulation of select muscles was evaluated to determine which single muscle or muscle pair best elevates the larynx and should be considered during future studies of neuromuscular stimulation in dysphagic patients. Hooked-wire ...

Algorithm visualization (AV) software graphically illustrates how algorithms work. Traditionally, computer science instructors have used the software as a visual aid in lectures, or as the basis for interactive laboratories. An alternative approach, inspired by Social Constructivist learning theory, is to have students construct and present their own visualizations. Notice that, in this alterna...
