General notes:

  1. the Syllabus for this course will be maintained on the instructor's website at www.berghel.net.
  2. the assigned readings will come from online resources.  URLs for the readings will be listed in the syllabus under "reading assignments." Note that reading assignments are for the current syllabus entry (i.e., read the assignment for the next class ahead of class)
  3. Tests and presentations will be posted on this online syllabus at least 10 days before the date. Homework may be periodically assigned, the value of which will be clearly indicated on the assignment.
  4. The current UNLV policies that govern instruction are posted on the website of the The Office of the Executive Vice President and Provost at http://provost.unlv.edu/policies.html. Pay special attention to the semester memo under "S".
  5. In addition, please familiarize yourself with the following:
    1. Writing Center Statement
    2. Tutoring Availability
    3. UNLV Rebel email account (note: UNLV recommends that you use this in all UNLV email communication!)
    4. Most recent UNLV campus police report
  6. UNLV Institutional Metrics @ December, 2016
  7. For homework purposes, relevant published online or offline resources are acceptable references. Quotation according to the principles of "fair use" under the U.S. Copyright laws apply. i.e., quoting and identifying a source is acceptable, plagiarizing a source is not. Any student found to have plagiarized will receive an "F" for the assignment in the first occurrence, and will receive an "F" in the course on the second occurrence. If you have any questions about this policy, consult with the instructor.
  8. I change the syllabus frequently (sometimes daily) based on the feedback on, and pace of, the lectures. As a result, the syllabus will typically lead the lectures by at most 2-3 class periods. An exception to this will be the three class periods prior to an exam. In this case, the class content will be frozen well in advance so that you know what material will be covered on the test.
  9. Grading will be on a standard "university scale," i.e., 90-100=A; 80-89=B; etc. I curve the exams so that the mean is always at least 75%. The contribution of exams, homework, projects, etc. will vary but will be explained in the syllabus at the time of assignment.
  10. There will most likely be two in class exams and a final exam. Your grade will be based on these exams with the caveat in note 11., below.
  11. All Exams will be "closed everything": e.g., "closed book," "closed notes," PDAs and computers turned off, cell phones off, etc. Any student caught with an active mobile device during an exam will receive a grade of F for the exam. Any student caught with an active mobile device during an exam for a second time will receive a grade of F for the course.
  12. Attendance may be taken. More than three unexcused absences will result in a 5% penalty on your final grade)

  13. In addition to any exams, homework, and quizzes that may be assigned, students registering for CS648 will be required to complete a semester project the details of which must be agreed upon no later than class time, Monday, on the 4th week of term. You may submit a proposal via email or meet in person to discuss, as you choose.

    (As a general goal, assume 3,500 word report with complete references in whatever standard format you choose (Chicago, APA, MLA, etc. This report is due at the start of the final exam period.)

ACM Code of ethics:

Students must also agree to abide by the Association for Computing Machinery's "Code of Ethics and Professional Conduct" for computing professionals ( http://www.acm.org/about/code-of-ethics ).
