Information received via friends tends to be trusted, and online social networks allow individuals to transmit information to many friends at once. By referencing known rumors from Snopes.com, a popular website documenting memes and urban legends, we track the propagation of thousands of rumors appearing on Facebook. From th...

Turbulent cascades

Turbulent cascades at high Reynolds numbers are explained briefly in terms of multipliers and multiplier distributions. Two properties of the multipliers ensure the existence of power laws for locally averaged energy dissipation rate: (a) the existence of a multiplier probability density function that is independent of the level of the cascade, and (b) the statistical independence of multiplier...

Expenditure Cascades

Evaluative judgments are known to depend heavily on context. For example, the same car that would have been experienced as having brisk acceleration in 1950 would seem sluggish to most drivers today. Similarly, a house of given size is more likely to be viewed as adequate the larger it is relative to other houses in the same local environment. And an effective interview suit is one that compare...
