with the basic mission of education, the transfer of knowledge, by allowing students to get by without having to master the knowledge. Furthermore, academic dishonesty creates an atmosphere that is not conducive to the learning process, which affects honest students as well. When honest students see cheaters escape detection, it can discourage student morale, as they see the rewards for their work cheapened. Cheating also undermines academia when students steal ideas. Ideas are a professional author's "capital and identity", and if a person's ideas are stolen it retards the pursuit of knowledge. If never formally retracted, fraudulent publications can remain an issue for many years as articles and books remain on shelves and continue to be cited. The case of S. Walter Poulshock, a 1960s early-career historian whose work was found to contain wholly fabricated material, was exposed in 1966 with the American Historical Review providing a warning on the topic. Nonetheless, his book was never removed from the shelves of many university libraries and (together with his related thesis) was still being cited in 2013, 47 years after it was intended to have been withdrawn by its publisher. Deterrence It used to be that in college the professor acted in loco parentis and was able to regulate student behavior as a parent. Honor codes First at the College of William and Mary in 1779, and then followed by schools like the University of Virginia in the 1850s and Wesleyan University in 1893, the students, with the agreement of faculty who declared themselves dedicated to ideals of democracy and human character, created honor codes. B. Melendez of Harvard University defined an honor code as a code of academic conduct that includes a written pledge of honesty that students sign, a student controlled judiciary that hears alleged violations, unproctored examinations, and an obligation for all students help enforce the code. Mixed judicial boards However, many people doubted the advisability of relying on an abstract notion of honor to prevent academic dishonesty. This doubt has perhaps led to the reality that no more than a quarter of American universities have adopted honor codes. Moreover, many professors could not envisage a student run trial process that treated faculty accusers fairly. In response to these concerns, in the middle of the twentieth century, many schools devised mixed judicial panels composed of both students and faculty. This type of academic integrity system was similar to
