Another of Hofstede's categories has to do with the way national cultures relate to uncertainty and ambiguity, and therefore, how well they may adapt to change. Generally, countries that show the most discomfort with ambiguity and uncertainty include Arab, Muslim, and traditional African countries, where high value is placed on conformity and safety, risk avoidance, and reliance on formal rules and rituals. Trust tends to be vested only in close family and friends. It may be difficult for outsider negotiators to establish relationships of confidence and trust with members of these national cultures.
Longer essays may also contain an introductory page that defines words and phrases of the essay's topic. Most academic institutions require that all substantial facts, quotations, and other porting material in an essay be referenced in a bibliography or works cited page at the end of the text. This scholarly convention helps others (whether teachers or fellow scholars) to understand the basis of facts and quotations the author uses to support the essay's argument and helps readers evaluate to what extent the argument is supported by evidence, and to evaluate the quality of that evidence. The academic essay tests the student's ability to present their thoughts in an organized way and is designed to test their intellectual capabilities.
