The term 'alpha female' originated in my field of animal behavior, but has acquired new meaning. It refers to women who are in charge, for example, by flirting and dating on their own terms. It is also used maliciously for a loud-mouthed, controlling woman who has no patience with deviating opinions.
I think Yandex is something in between two different cultures. One originated from the old Soviet culture of the scientific institute. It was a free atmosphere of scientists, maybe too free because nobody cared about making money. Another origin is something close to what you usually see in California startups.
