3h-weekly meetings, including (i) lectures by instructor, (ii) student presentations, and (iii) class discussions.

Students will be assigned readings, and will make presentations about the assigned readings. They will also have individual term paper projects, which they will have the opportunity to develop throughout the term, and present before the term ends.

Reading/Presentations: (30%)

Each student will have to make 3 presentations throughout the term. For each presentation, each student will have one review + one research papers to read and present. The student should present the research paper, but must use the review paper to introduce the audience to concepts, terminology, or recent findings. Each presentation is worth 10%.

Participation to class discussion: (10%)

Participation to class discussion will be marked.

Term paper project: (20%)

Every student will choose a subject from a list proposed by the instructor, gather the appropriate literature on the subject, and write a term review paper (10%).

Before the end of the term, each student will have the opportunity to make a presentation of their paper in front of an audience (10%).

Mid-term written exam: (25%)

Final oral exam: (15%)

Assignments that are submitted after the stated deadline will be deducted 5 % a day of the grade up to the end of the first week and 25 % thereafter for each week the assignment is late.

Please refer to the University of Manitoba General Calendar for regulations regarding plagiarism and cheating and examination impersonation.

Please note that assignments, reports, or exams which are illegible or poorly written may be subject to refusal or deduction of the final grade.

Term papers will be assigned to each student. Information should be gathered from research/review papers and summarized into a short report. The length of each report and the quantity of references to be used will be discussed in class.

The list of topics will be provided in class.
