Gini coefficient of national income distribution around the world. This is based on 1989 to 2009 data, estimated by the CIA. Some are pre-tax, others post-tax income. The Gini coefficient (also known as the Gini index or Gini ratio ) is a measure of statistical dispersion developed by the Italian statistician and sociologist Corrado Gini and published in his 1912 paper "Variability and Mutability" ( Italian : Variabilità e mutabilità ). [ 1 ] [ 2 ] The Gini coefficient measures the inequality among values of a frequency distribution (for example levels of income ). A Gini coefficient of zero expresses perfect equality, where all values are the same (for example, where everyone has an exactly equal income).
Art by Laetitzia As we all know, communication is essential in society. Advancements in technology have transformed the way that we correspond with others in the modern world. We live in an era when launching apps, using an online QR code generator for immediate information, following turn-by-turn map navigation on our phones, and microblogging with tweets and instant photos have become the norm. Because of the constant buzz in our technological world, it's easy to forget how important communicating face-to-face is. When conversing old-school style, it's not only speech we verbalize that matters, but what our nonverbal gestures articulate as well. Body language is truly a language of its own.
Dec. 30, 2009 — 2009 may well be remembered for its scandal-ridden headlines, from admissions of extramarital affairs by governors and senators, to corporate executives flying private jets while cutting employee benefits, and most recently, to a mysterious early morning car crash in Florida. The past year has been marked by a series of moral transgressions by powerful figures in political, business and celebrity circles. New research from the Kellogg School of Management at Northwestern University explores why powerful people - many of whom take a moral high ground - don't practice what they preach. Researchers sought to determine whether power inspires hypocrisy, the tendency to hold high standards for others while performing morally suspect behaviors oneself. The research finds that power makes people stricter in moral judgment of others - while being less strict of their own behavior.
