College cheating is prevalent, with rates ranging widely from 9 to 95% (Whitley, 1998). Research has been exclusively conducted with enrolled college students. This study examined the prevalence of cheating in a sample of college alumni, who risk less in disclosing academic dishonesty than current students. A total of 273 alumni reported on their prevalence and perceived severity of 19 cheating behaviors. The vast majority of participants (81.7%) report having engaged in some form of cheating during their undergraduate career. The (...) most common forms of cheating were “copying from another student's assignment” and “allowing others to copy from your assignment.” More students reported cheating in classes for their major than other classes. Males and females cheated at the same rates in classes for their major, and males reported higher rates of cheating than females in nonmajor classes. Respondents reported that their top reasons for cheating were “lack of time” and “to help a friend.”. (shrink)

Ontology languages for the Semantic Web have their strengths and weaknesses, in particular in the light of deploying them for biological and medical information systems. We survey and compare the Description Logics-based OWL languages, and the DL-Lite and DLR families of languages. Language choices that an ontology developer has to make are, among others, expressivity with n-ary relations (where n > 2) and more role properties versus ontology usage for data-intensive tasks. Guidelines are suggested to facilitate choosing the language best (...) fitted for a task. (shrink)
