SAMPLE ASSIGNMENT

The first unit of Global Gender Issues examines the impact of the HIV/AIDS pandemic on young women in
Kenya and on adult men in Uganda. As expected, significant gender and age-related differences
characterize the experiences of these two groups. At the same time, these different experiences are often
the result of common sociocultural factors such as transactional sex relationships, masculine sexual
privilege, and desire for a modern lifestyle. This essay asks you to compare and contrast the way these
factors play out in the lives of young Kenyan women and adult Ugandan men.
Sociocultural factors have played a central role in putting young women and adult men at risk for
HIV/AIDS in Kenya and Uganda:
First: explain the importance of accounting for sociocultural factors in assessing populations at
risk for HIV/AIDS.
Second: compare and contrast the way that transactional sex relationships put young
Kenyan women and adult Ugandan men at risk for HIV/AIDS.
Third: compare and contrast the way masculine sexual privilege puts young Kenyan women
and adult Ugandan men at risk for HIV/AIDS.
Fourth: compare and contrast the way desire for a ‘modern’ lifestyle puts young Kenyan
women and adult Ugandan men at risk for HIV/AIDS (Be sure to discuss changing ideas
about both consumption and interpersonal relationships).
