1. Is there a difference between cultural diffusion due to globalization vs. cultural diffusion due to amalgamation? 2. Cultural transmission vs. diffusion TPR says this: "a meme is an element of culture that spreads from person to person; cultural transmission is concerned with how this occurs" Isn't this cultural DIFFUSION? Cultural transmission is strictly "vertical" exchange of culture - i.e. between generations; whereas I see cultural diffusion as strictly horizontal exchange - i.e. between different social groups. If not, how do you distinguish between transmission and diffusion?
