Prediction of Educational Outcome After Pediatric Traumatic Brain Injury.

Objective: Evaluation of the predictive value of neuropsychological test scores with respect to special education placement following pediatric traumatic brain injury (TBI). Study Design: Longitudinal follow-up and hierarchical logistic regression analyses. Setting: Regional rehabilitation center. Participants: Consecutive series of referrals, including 58 children with TBI and no confounding premorbid histories or other complicating factors. Main Outcome Measures: Special education placement at, respectively, 12 and 24 months postinjury. Results: Children who obtained a composite T score of less than 45 on the California Verbal Learning Test--Children's Version during initial postinjury neuropsychological assessment were 8-13 times more likely to be placed in special education 12-24 months later compared with children who obtained higher scores. Conclusions: Neuropsychological test scores are not only sensitive to acute injury severity but also explain a substantial proportion of the variance in educational outcome after pediatric TBI, above and beyond that accounted for by demographic and medical variables.

From psychophysics to the clinic: missteps and advances

People live in different oral sensory worlds. This variation affects health and quality of life. The need to make valid comparisons across individuals/groups to reveal this variation highlighted invalid use of conventional labeled scales (e.g., visual analogue, category scales). Valid comparisons can be made with magnitude matching and the general Labeled Magnitude Scale (gLMS) employing multiple standards (real and remembered), thus permitting associations between oral sensation, preferences, intake (e.g., fats, vegetables), and health outcomes (e.g., cancer, phantoms, burning mouth syndrome). These measurement insights broadly apply to sensory/hedonic assessment of differences across groups in many different fields. As an illustration, we assess differences across groups experiencing different types of pain.     

Metaphor-based meaning excavation

Excavating the meaning of a target term is a challenge facing information sciences and various applications of Web 3.0. In this paper, we present a novel method for excavating the meaning of a target term by analyzing metaphors in which the term is embedded. More specifically, we (1) review some of the basic theoretical difficulties associated with the dominant cognitive theories of metaphor; (2) outline a mathematical model of metaphor that addresses some of these difficulties; (3) introduce a novel method for excavating metaphor-based meaning; and (4) illustrate the relevance of the methodology and the potential applications of the model with a concrete example.     

Categorical proof theory of classical propositional calculus

We investigate semantics for classical proof based on the sequent calculus. We show that the propositional connectives are not quite well-behaved from a traditional categorical perspective, and give a more refined, but necessarily complex, analysis of how connectives may be characterised abstractly. Finally we explain the consequences of insisting on more familiar categorical behaviour.

Visualizing large-scale human collaboration in Wikipedia

Volunteer-driven large-scale human-to-human collaboration has become common in the Web 2.0 era. Wikipedia is one of the foremost examples of such large-scale collaboration, involving millions of authors writing millions of articles on a wide range of subjects. The collaboration on some popular articles numbers hundreds or even thousands of co-authors. We have analyzed the co-authoring across entire Wikipedias in different languages and have found it to follow a geometric distribution in all the language editions we studied. In order to better understand the distribution of co-author counts across different topics, we have aggregated content by category and visualized it in a form resembling a geographic map. The visualizations produced show that there are significant differences of co-author counts across different topics in all the Wikipedia language editions we visualized. In this article we describe our analysis and visualization method and present the results of applying our method to the English, German, Chinese, Swedish and Danish Wikipedias. We have evaluated our visualization against textual data and found it to be superior in usability, accuracy, speed and user preference.
