I examine how firms use alliances to respond to the alliance networks of their rivals, by either allying with their rivals’ partners or by building countervailing alliances.

Cospecialized alliances by rivals may involve exclusivity, precluding alliances with the rival...

We investigated the drawing signs in 200 schizophrenic and 200 normal individuals on Draw A Person test in Pakistan. The sample consisted of men and women between ages of 20 to 50 years in two provinces (Punjab and Khyber Pakhtun-Khwa) of Pakistan. We used Koppitz (1971) method to administer and score the test and selected 40 Emotional Indicators (EIs) from the literature and found 26whichsigni...

Positivity reduces substantially the allowed domain for spin observables. We briefly recall some methods used to determine these domains and give some typical examples for exclusive and inclusive spin-dependent reactions.
