Strengths and weaknesses of global health networks

Posted: 26 Apr 2016 12:30 PM PDT

Tuberculosis, childhood pneumonia, maternal death in childbirth, tobacco-related illnesses: how do global health networks select issues and seek to address these public health challenges that affect the world's poorest countries? How do these networks arise and garner resources? How adaptable are they to changing conditions, national governments, and shifting coalitions and interests? Why are some conditions targeted while others, equally widespread and serious, are not? And finally, are global networks useful at all?

Women who are cheated on 'win' in the long run; new women 'lose'

Posted: 26 Apr 2016 09:01 AM PDT

Women who lose their unfaithful mate to another woman actually win in the long run, according to new research.'Our thesis is that the woman who 'loses' her mate to another woman will go through a period of post-relationship grief and betrayal, but come out of the experience with higher mating intelligence that allows her to better detect cues in future mates that may indicate low mate value. Hence, in the long-term, she 'wins."
