Technological Diffusion
Fashion/beauty
Explanation:
A Diffusion is the way that a new idea, innovation or management scheme permeates a society no matter the socio-economic status.
Technological diffusion has been a large impact on the food choices we make now since food can be easily ordered via APPs on smart phones. The cleaver way of tracking customers makes it easy for companies to send adds specific to that person's choice based on the websites that they have visited.
The fashion and beauty industry has also experience a diffusion by making products and techniques more affordable and by engaging their audience using persons other than celebrities. This makes the products seem reachable by everyone who willingly engages. Wanting to be beautiful, fit, etc has encouraged individuals to alter the food they eat with the hopes of becoming, healthier, thinner or having more muscle mass etc.
This is how two types of diffusion change the way people eat.
The African Americans in the roaring 20s were treated unfairly and badly. Slavery was a problem in the 20s and African Americans were kicked out of their homes and lost jobs. Many African Americans worked on plantations and were living in harsh conditions. Immigrants also worked on plantations and were refused many jobs due to their background. Many immigrants had a hard time finding jobs and being able to support their family. The stock market crash made it harder for immigrants and African Americans to live. More people were kicked out of their homes due to the stock market crash and many people lost their lives because they were poor and did not have the funds to support their families.
