Smells Like Generosity

This academic paper, “Oxytocin Increases Generosity in Humans,” details the study of the effect on material generosity from greater-than-normal doses of a hormone in a small sample of test subjects. The game used during the experiment is a variation of the money-splitting game we considered as part of our exploration of network exchange theory.

Information Cascade in Dietary Research

http://www.nytimes.com/2007/10/09/science/09tier.html
http://tierneylab.blogs.nytimes.com/2007/10/09/how-the-low-fat-low-fact-cascade-just-keeps-rolling-along/
The article that I’ve chosen for this post (first link) is about how the medical world was duped into the cascading idea that a low-fat diet would lower the risk of heart disease. John Tierney, a science columnist for The New York Times, cites Gary Taubes’ book, Good Calories, Bad Calories to explain the steps […]

“The coevolution of choosiness and cooperation” from Nature magazine
http://en.wikipedia.org/wiki/Evolutionarily_stable_strategy
Supplementary Wikipedia article: “Evolutionarily Stable Strategy”
The motivation for analyzing choosiness and cooperation between individuals is to seek a better understanding of biological systems and human societies. The interaction that occurs specifically between non-relatives is what the article focuses on.
The way choosiness and cooperation relate to the […]

Hardy-Weinberg/ Nash Equilibrium

http://findarticles.com/p/articles/mi_qa3659/is_200606/ai_n17175649/pg_3
In looking into the Hardy-Weinberg equilibrium, this principle helps explain the frequencies of alleles and genotypes in a population that remains constant from generation to generation. This of course occurs only when certain factors are kept constant. This principle works hand in hand with Mendelian segregation and recombinations of alleles. The five factors include random […]

Bring Out Your Dead: Epidemiology, Transportation Networks and Migration Patterns

Watching Monty Python the other day, I found my thoughts wandering once again back to Networks 204 and Gladwell’s description of a syphilis epidemic in Baltimore: how it spread from the projects along local highways during summer months and contracted during the winter. Explicitly drawing a connection between contagious viral diseases and transportation networks […]

Networks of Science and Art

Throughout the course, I have enjoyed the fact that our social networks are compared to “harder” sciences (potential energy of an auction or the current of the “water cycle” of PageRank). As a biologist, I am more familiar with the concepts of physics and math than I am with those of economics or sociology, […]

Word Networks in the Human Brain

In a study at Kansas University conducted by Michael Vitevich, an attempt is made to map out the words of our vocabulary as they are represented in the human brain. What Vitevich hopes to learn from charting out our vocabularies in the brain is how victims of brain trauma regain their language skills, but […]
