We tested the hypothesis that engagement in a few, brief writing assignments in a nonmajors science course can improve student ability to convey critical thought about science. A sample of three papers written by students (n = 30) was coded for presence and accuracy of elements related to scientific writing. Scores for different aspects of scientific writing were significantly correlated, sugge...

Constraint Handling Rules (CHR) is a high-level language commonly used to write constraint solvers. Most CHR programs depend on the refined operational semantics, resulting in an obfuscated logical reading and potential misbehavior under the theoretical operational semantics. We introduce two source to source transformations: guard simplification and occurrence subsumption. By removing redundan...

The mechanisms that underlie the ability to read and write music remain largely unclear compared to those involved in reading and writing language. We had the extremely rare opportunity to study the cerebral localization of the center for reading and writing music in the case of a professional trombonist. During rehearsal immediately before a concert, he suffered a hemorrhage that was localized...

Constraint Handling Rules (CHR) is a high-level language commonly used to write constraint solvers. Most CHR programs depend on the refined operational semantics, resulting in an obfuscated logical reading and non-termination or worse under the theoretical operational semantics. We introduce a source to source transformation called guard simplification which allows CHR programmers to write self...
