Cultures that often create systems of formal rules as a way to provide more security
and reduce risk are called high-uncertainty-avoidance cultures.

Answers

Answer: True

Explanation:

Uncertainty avoidance refers to the difference in cultures based on the tolerance level that they have when it comes to unpredictability.

People in cultures that has high uncertainty avoidance minimize unforeseen or unknown circumstances and have rules in place which will help in mitigating the risks. On the other hand, low uncertainty avoidance cultures are quick to accept changes and have few rules.

Answers

Answer:

Explanation:

the author name is Vera Tripodi (u got an extra l in there) n paper is "The Value of Diversity and Inclusiveness in Philosophy. An Overview." the main theme is that individuals are marginalized in study of philosophy due to the big gender gap.

philosophy is highly subjective n its study is heavily influenced by its scholars. its well known among academia that there is a gender gap - most professors and researchers are men with very few women. while that may not be significant in experiment-based subjects like science and engineering, that is not the case for many humanity studies. philosophy is particularly personal and the perspective of a male scholar can be very different from that of a female colleague. this leads to the conclusions drawn from such studies may be biased or even discriminated female population.

Answer:

Explanation:

The argument was that study of philosophy was biased and treated women different from men. The author cited one of the earliest philosopher:  Aristotle. His "notions of “form” and “matter” reflect sexual differences: the former is intrinsically linked to “being male” and latter to “being feminine”. This gender association poses a problem for feminists: Aristotelian matter and form are not treated as equal and the form has priority over the matter." Her conclusion is that "the sexism of the distinction between form and matter is inherent to Aristotle’s metaphysic."
