A framework for measuring quality in the emergency department
There is increasing concern that medical care is of variable quality, with variable outcomes, safety, costs and experience for patients. Despite substantial efforts to improve patient safety, some studies suggest little evidence of reductions in adverse events. Furthermore, there is limited agreement about what outcomes are expected and whether increased expenditure results in a real improvement in outcome or experience. In emergency medicine, many countries have developed specific indicators to help drive improvements in patient care. Most of these are time based and there is a lack of consensus regarding which indicators are high priority and what an appropriate framework for measuring quality should look like
A parent-centered radial layout algorithm for interactive graph visualization and animation
We have developed (1) a graph visualization system that allows users to
explore graphs by viewing them as a succession of spanning trees selected
interactively, (2) a radial graph layout algorithm, and (3) an animation
algorithm that generates meaningful visualizations and smooth transitions
between graphs while minimizing edge crossings during transitions and in static
layouts.
Our system is similar to the radial layout system of Yee et al. (2001), but
differs primarily in that each node is positioned on a coordinate system
centered on its own parent rather than on a single coordinate system for all
nodes. Our system is thus easy to define recursively and lends itself to
parallelization. It also guarantees that layouts have many nice properties,
such as: it guarantees certain edges never cross during an animation.
We compared the layouts and transitions produced by our algorithms to those
produced by Yee et al. Results from several experiments indicate that our
system produces fewer edge crossings during transitions between graph drawings,
and that the transitions more often involve changes in local scaling rather
than structure.
These findings suggest the system has promise as an interactive graph
exploration tool in a variety of settings
Reply to the comment by Carmelo Anile on the paper "Complexity analysis of the cerebrospinal fluid pulse waveform during infusion studies"
Veterinary technology is an emerging profession within the veterinary and allied animal health fields in Australia and affords graduates the opportunity to contribute to the small but growing body of literature within this discipline. This study describes the introduction of a contextualised assessment task to develop students’ research capability, competence and confidence in professional writing, and to engage them with the academic publishing process. Students worked in self-selected dyads to author a scientific case report, of publishable standard, based on authentic cases from their clinical practicum. Intrinsic to the task, students attended a series of workshops that explored topics such as critiquing the literature, professional writing styles and oral presentation skills. Assessment was multi-staged with progressive feedback, including peer review, and culminated with students presenting their abstracts at a mock conference. Students reported the task to be an enjoyable and valuable learning experience which improved their competence and confidence in scientific writing; supported by a comparison of previously submitted work. Linking scientific writing skills to clinical practice experiences enhanced learning outcomes and may foster the professionalisation of students within this emerging discipline
Writing Through the Senses in the Basic Writing Classroom
This study attempts to determine the impact and effectiveness of sensory writing strategies in the initial drafting stages of narrative writing when used in the Basic Writing classroom. Inspired originally by my work with English As a Second Language (ESL) students at a middle eastern international school and the works of feminist theorists, such as Hélène Cixous and Gloria Anzaldua, students use sensory experiences as the foundation for the generation of narrative content. This early draft is then quantitatively and qualitatively compared to previous work completed by the student. I found that certain populations of students, based on gender, classroom dynamics, and writing preferences, seemed to be particularly impacted by these strategies. This includes how students were influenced affectively, but also in the style of their writing, and in the perception of their work. Also included is how a student with dyslexia was impacted by these strategies
Imaging isodensity contours of molecular states with STM
We present an improved way for imaging the local density of states with a
scanning tunneling microscope, which consists in mapping the surface topography
while keeping the differential conductance (d/d) constant. When
archetypical C molecules on Cu(111) are imaged with this method, these
so-called iso-d/d maps are in excellent agreement with theoretical
simulations of the isodensity contours of the molecular orbitals. A direct
visualization and unambiguous identification of superatomic C orbitals
and their hybridization is then possible
Electroluminescence from a polythiophene molecular wire suspended in a plasmonic scanning tunneling microscope junction
The electroluminescence of a polythiophene wire suspended between two
metallic electrodes is probed using a scanning tunneling microscope. Under
positive sample voltage, the spectral and voltage dependencies of the emitted
light are consistent with the fluorescence of the wire junction mediated by
localized plasmons. This emission is strongly attenuated for the opposite
polarity. Both emission mechanism and polarity dependence are similar to what
occurs in organic light emitting diodes (OLED) but at the level of a single
molecular wire.Comment: to be published in Physical Review Letter
