The majority of the research thus far has focused on validating the automated scoring tools by comparing the electronic scores to human scores of writing or other measures of writing skills, and exploring the predictive validity of the automated scores. However, very little research has investigated possible effects of the essay prompts. This study endeavoured to do so by exploring test scores for three different prompts for the ACCUPLACER®WritePlacer®Plus test which is scored by the IntelliMetric® automated scoring system. The results indicated that there was no significant difference among the prompts overall; among males, between males and females, by native language or in comparison to scores generated by human raters. However, there was a significant difference in mean scores by topic for females.KeywordsElectronic scoring; Essays; Topic effect; ACCUPLACER®; Writing assessmentCindy L.

Pediatric Minor Traumatic Brain InjuryKevin E. Gordon, MD, MS,Department of Pediatrics, Division of Pediatric Neurology, Dalhousie University and IWK Health Centre, Halifax, Nova Scotia, Canada.The literature surrounding minor traumatic brain injury is complex, methodologically challenging, and controversial. Although we lack a consistent standardized definition, the annual rate is likely in excess of 200 per 100,000 children. The proportion of children with minor traumatic brain injury who will require neurosurgery is certainly <1%. Several studies are underway that have thepotential to significantly advance our understanding of the specific risk factors for intracranial injury and more specifically neurosurgical injury. The mortality within children is very low, with estimates of 0% to 0.25%. V irtually all studies of the prognosis of minor brain injury in children have reported no long-term behavioral or cognitive sequelae as a specific result of the brain injury. Symptoms fall in 4 domains: somatic, cognitive, sleep/fatigue, and affective. Limited pediatric studies are available to assist clinicians in the prognosis or in optimizing recovery. Until further studies are available, a conservative approach is recommended. Children with suspected concussions should be removed from activity and observed. Children with symptomatic concussions must be limited to no physical activity. Adolescents and families need to self-monitor symptoms and limit environments or circumstances that exacerbate any symptoms. When symptoms resolve, a gradual progressive return to play is currently recommended. The recurrence risk for subsequent concussions is elevated, but there is limited documentation of the effectiveness of preventative efforts. Much remains to be learned.Keywordshead injuries; brain concussion; review; tomography; x-ray computed; prognosis; diagnosis; preventionProceedings of SPIE - The International Society for Optical Engineering, v 7980, 20113.
