This study was designed to assess the effects of symmetry and plane of presentation on the determination of the perceptual center of flat figures. Experiment 1 demonstrates the existence of effects in improving center determination, both in the number of sides of the shape and in rotational and reflective symmetry (confounded in the experiment). Experiment 2 shows that the presentation plane has no effect on center determination. In Experiment 3, we divide the effects of the two symmetry types, showing that rotational symmetry alone is as effective as the presence of both symmetry types--that is, the presence of symmetry axes is not very useful in finding perceived centers.
Paper-based medical record systems are becoming obsolete with the advent of electronic medical record (EMR) systems. With EMRs, patient data can be accessed instantly, patients can be tracked intelligently, and safeguards can help prevent medical errors. By integrating a universal nursing language, such as the Perioperative Nursing Data Set (PNDS), into EMR systems, nurses can document the nursing care they give to patients. This allows nurses to show the value of their role in the OR, promote nursing, and explain how their actions help meet National Patient Safety Goals. The transition to an EMR system for Jackson Health System, Miami, is discussed, including integration of the PNDS into the EMR system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
