the “Separate Spheres” theory was still applied to how women and men were supposed to act in society. The theory is that women should remain at home‚ because they are “delicate‚ fragile creatures” who shouldn’t be out in a “man’s world”. Men should be masculine and tough; they should be in charge of financially supporting his family and be in the “dangerous business world”. That left the women at home to take care of the household and children. The logic behind “Separate Spheres” was that “women

The Evolution of Public Relations Introduction In order for us to understand how public relations have evolved through history‚ we must first understand what public relations are. Public relations as defined by (Wilcox and Cameron 2004) that Professors Long and Hazelton believe it to be‚ “ a communication function of management through which organizations adapt to alter‚ or to maintain their environment for the purpose of achieving organizational goals”(p.5). With that said we could now go back

c/a c a = 8 3 = 1.633 2 2. Show that the atomic packing factor for HCP is 0.74. This problem calls for a demonstration that the APF for HCP is 0.74. Again‚ the APF is the ratio of the total sphere volume‚ VS‚ to the unit cell volume‚ VC. For HCP‚ there are the equivalent of six spheres per unit cell‚ and thus ⎛4πR3⎞ VS = 6⎜ 3 ⎟ = 8πR3 ⎝ ⎠ Now‚ the unit cell volume is the product of the base area times the cell height‚ c. The base area can be calculated as follows. The following
