1. what is the widower effect?

2. what are the two things christakis discovered about how social networks work?

3. what is a cluster? what conclusions did christakis come to using clusters regarding obesity?

4. what are the reasons behind this clustering of obesity?

5. what other phenomena besides obesity can be attributed to social network clusters?

6. can clustering be attributed to emotions? what implication does this hold for humanity?

7. what other factors might impact how effective a social network can be?

8. explain what super organisms are and provide an example.

9. according to christakis, why do we form social networks?

1.While the “caregiver burden,” or the health effect on a partner when a spouse becomes ill, and the “widower effect” – the chances a survivor will die after a spouse's death – have each been studied separately, the new study is the first to examine them together
2.Harvard professor and sociologist Nicholas Christakis has shown that there's more to think about regarding social networks such as Facebook, MySpace, Flickr, and Twitter than considerations of In our empirical work on obesity, we found two lines of suggestive evidence for a spread of norms.
3.We confirmed Christakis and Fowler's basic finding that BMI and obesity do indeed cluster socially, but we found that body size norms accounted for only a small portion of this effect (at most 20%) and only via 1 of the 3 pathways. Conclusions.
4.The heritability of weight is known to be high, with strong intergenerational transmission of obesity.3,4 We were surprised that the authors did not mention genetic factors as a possible cause of the family-based social patterning of obesit
5.As diverse phenomena can spread in social networks, we investigated whether happiness also does so. The association between the happiness of individuals connected to each other, and the clustering within the network, could be attributed to at least three processes: induction, whereby 
6.Each of these four attributes of human thought has been the subject of much controversy, but at this point in our history, one is unlikely to find much Such considerations imply either thatemotion does not cause behavior or that some part of emotion other than conscious feelings can cause behavior.
7.The best that anyone can hope for is an influencer in a specific domain of knowledge b. Bandwidth: The influencer's ability to transmit his expert knowledge through a social media channel. Please note: Active influencers in one channel may not even be present on another channel
8.The term superorganism is used most often to describe a social unit of eusocial animals, where division of labour is highly specialised and where individuals are not able to survive by themselves for extended periods. Ants are the best-known example of such a superorganism
9.We're all embedded in massive social networks that have massive influences on our well-being,” claims Dr. Nicholas Christakis, a professor from Harvard University. In a recent TEDX talk, Dr.Christakis, argues that because people are inter-connected, their health must be interconnected as well. 

The answer is c because the law is facts
