This study compared the effects of problem-focused and solution-focused coaching questions on positive and negative affect, self-efficacy, goal approach, and action planning. A total of 225 participants were randomly assigned to either a problem-focused or solution-focused coaching condition. All participants described a real-life problem that they wanted to solve and set a goal to solve that p...

The problem of radio channel assignments with multiple levels of interference depending on distance can be modeled using graph theory. The authors previously introduced a model of labeling by real numbers. Given a graph G, possibly infinite, and real numbers k1, k2, . . . , kp ≥ 0, a L(k1, k2, . . . , kp)-labeling of G assigns real numbers f(x) ≥ 0 to the vertices x, such that the labels of ver...
