Test the binary relations on S for reflexivity, symmetry ,antisymmetry, and transitivity

A)
S = Q
X p Y <-> ABS(X) <= ABS(Y)

B)
S = Z
X p Y <-> x -y is an integral multiple of 3

C)
S = N
X P Y <-> X is odd

D)
S = Set of all squares in the place
S1 p S2 <-> length of side of S1 = length of side S2

E)
S = set of finite-length strings of characters
X p Y <-> number of characters in x = number of characters in y

Global Public Relation Trends

I need to prepare a 1800-2100 word paper that addresses the following questions:
a. What are the key global Public Relations trends?
b. What are the differences in publicity and advertising in terms of their impact on publics?
c. When do you need proactive Public Relations planning? And, when do you utilize reactive crisis management?

In addition, synthesize the Public Relation concepts learning by describing the impact of positive and negative Public Relations in a daily personal life and provide two examples of each in the paper.

Please provide ideas to help start the paper.
