Please remember that my lectures and course materials are protected by U.S. copyright law and by University policy.
I am the exclusive owner of the copyright in those materials I create. You may take notes and make copies of course
materials for your own use. You may also share those materials with another student who is enrolled in or auditing
this course. You may not reproduce, distribute or display (post/upload) lecture notes or recordings or course materials
in any other way - whether or not a fee is charged - without my express prior written consent.
You also may not allow others to do so. If you do so, you may be subject to student conduct proceedings under
the UC Davis Code of Academic Conduct.
Code of Academic Conduct
The Code of Academic Conduct exists to support high standards of behavior and to ensure fair evaluation of student learning. Students who violate the Code of Academic Conduct are subject to disciplinary sanctions that include censure, probation, suspension, deferred separation or dismissal from the University of California.
The code can be found at this link , or
Cheating will be taken extremely seriously, and will be referred to Student Judicial Affairs.
In particular, it is OK to discuss homework problems with others, but you have to write the solutions in
your own words . You cannot copy solutions from other students, books or the Internet.
For the midterms and the final, you are not allowed to discuss problems with anyone else or search the Internet.
It follows exactly the same rules as the in class exam. If we observe that your solutions match someone else's or
some Internet resource, your exam grade will be annuled.
Academic Participation Requirements
The campus requires students to verify that they have begun each course for which they are registered via the Academic Participation program. This program also encourages students to acknowledge their responsibilities regarding academic integrity and the Code of Academic Conduct, reinforcing our campus culture of honesty.
MyUCDavis will notify students online and through email on the first day of instruction to complete their Academic Participation verification no later than the quarter add deadline. Failing to verify academic participation by this deadline may result in a reduction of the financial aid award.
Please see more details by this link .
