TL;DR: This paper characterizes the feasible solutions of P1, shows that P1 is equivalent to a problem of minimizing a concave quadratic objective function over a convex set, and applies a method developed by Tul to solve such a problem to yield a procedure for the zero-one integer programming problem.
Abstract: Consider the zero-one integer programming problem P1i:minimize Z = c'x subject to Ax ≦ b, 0 ≦ xi ≦ 1, xj = 0 or 1, j = 1, 2, ', n, where A is an m × n matrix, c' = c1, ', cn, x' = x1, ', xn, and b is an m × 1 vector with b' = b1, ', bm. Assume the elements of A, b, c are all rational. This paper characterizes the feasible solutions of P1, shows that P1 is equivalent to a problem of minimizing a concave quadratic objective function over a convex set, and applies a method developed by Tul to solve such a problem to yield a procedure for the zero-one integer programming problem.

TL;DR: This paper found that there was a curvilinear relationship between communication discrepancy and immediately measured opinion change, and that with delayed measurement retention of the changed opinion would dissipate over time.
Abstract: 106 Ss made judgments of numerosity after they were exposed to the judgments of male confederates. There was a curvilinear relationship between communication discrepancy and immediately measured opinion change. The prediction that with delayed measurement retention of the changed opinion would dissipate over time was not significantly supported. A significant linear trend interacted with the curvilinear trend in the immediate measurement condition. These results were interpreted as being consistent with the sleeper-effect phenomenon.
