Abstract: Student data-to-insight-to-action-to-learning analytics system and method use an evidence-based action knowledge database to compute student success predictions, student engagement predictions, and student impact predictions to interventions. The evidence-based action knowledge database is updated by executing a multi-tier impact analysis on impact results of applied interventions. The multi-tier impact analysis includes using changes in key performance indicators (KPIs) for pilot students after each applied intervention and dynamic matching of the pilot students exposed to the appropriate interventions to other students who were not exposed to the appropriate interventions.

Abstract: A method to detect invalid polygons that are inputted by users using a graphical user-interface is presented. The method selects pairs of lines that are used to define the polygon and tests to determine if the lines crossover. If there are no crossovers, then the polygon is a valid polygon. If there is a pair of lines that do crossover one another, then the polygon is an invalid polygon. Such a method is useful in teaching polygons and their properties to novices and students.

Abstract: The present invention is directed to methods of preventing, inhibiting, reversing and/or ameliorating complications in those having or at risk for systemic inflammatory response syndrome, e.g., sepsis, including multiple organ dysfunction syndrome, pancreatitis, burns, trauma, and complications of sepsis such as bacteremia, pneumonia, urinary tract infections, wound infections, and drug reactions. The methods comprise administration of an effective amount of at least one of a selective inhibitor of cyclooxygenase-2, a drug which stimulates one or more PGE2 receptors or a drug which interferes with binding of PGE2 to one of more PGE2 receptors.

Abstract: It has been found that arginine serves to increase the receptivity of cells to lymphokines such as interleukin-2 and interferon. An improved method for treating a mammal with one or more lymphokines is disclosed wherein said improvement comprises administering said one or more lymphokines to said mammal in combination with an amount of arginine effective to increase the receptivity of cells of said mammal to said one or more lymphokines.
