A Venn diagram is simple if at most two curves intersect at any given point. A recent paper of Griggs, Killian, and Savage [Elec. J. Combinatorics, Research Paper 2, 2004] shows how to construct rotationally symmetric Venn diagrams for any prime number of curves. However, the resulting diagrams contain only n n/2 intersection points, whereas a simple Venn(More)

The effectiveness of male circumcision in preventing transmission of HIV from females to males has been established. Those who are now advocating its widespread use face many challenges in convincing policy-makers and the public of circumcision's value. We suggest that frames are a useful lens for communicating public health messages that may help promote(More)
We establish a new lower bound for the number of sides required for the component curves of simple Venn diagrams made from polygons. Speciically, for any n-Venn diagram of convex k-gons, we prove that k (2 n 2 n)=(n(n 2)). In the process we prove that Venn diagrams of seven curves, simple or not, cannot be formed from triangles. We then give an example(More)
Now that male circumcision has been shown to have a protective effect for men against HIV infection when engaging in vaginal intercourse with HIV-infected women, the research focus needs to shift towards the operational studies that can pave the way for effective implementation of circumcision programs. Behavioral research is needed to find out how people(More)
BACKGROUND Nutrition is the intake of food in relation to the body's dietary needs. Malnutrition results from the intake of inadequate or excess food. This can lead to reduced immunity, increased susceptibility to disease, impaired physical and mental development, and reduced productivity. OBJECTIVE To perform a systematic review to assess research(More)
<i>Water Columns</i> consists of three extremely lightweight, passively actuated kinetic sculptures that take advantage of the relative tendency of wood to absorb moisture from the atmosphere to create passive engines for actuation of a long array of bi-laminate filaments. The sculptures change shape over the course of the day as relative humidity rises and(More)
