An offensive alliance in a graph Γ = (V,E) is a set of vertices S ⊂ V where for every vertex v in its boundary it holds that the majority of vertices in v’s closed neighborhood are in S. In the case of strong offensive alliance, strict majority is required. An alliance S is called global if it affects every vertex in V \S, that is, S is a dominating set of Γ. The offensive alliance number ao(Γ)...

This study examined relationships among maltreatment experience, therapeutic alliance formation, and treatment outcome in a sample of 38 psychiatrically hospitalized adolescents. It was hypothesized that the experience of maltreatment would interfere with alliance formation, thereby compromising the effectiveness of therapy. Results indicated that maltreatment, multiplicity of maltreatment, and...

A global o ensive alliance in a graph G = (V; E) is a subset S of V such that for every vertex v not in S at least half of the vertices in the closed neighborhood of v are in S. The cardinality of a minimum size global o ensive alliance in G is called the global o ensive alliance number of G. We give an upper bound on the global (strong) o ensive alliance number of a graph in terms of its degre...

This paper studies a contest in which players with unobservable types may form an alliance in a pre-stage of the game to join their forces and compete for a prize. We characterize the pure strategy equilibria of this game of incomplete information. We show that if the formation of an alliance is voluntary, players do not reveal private information in the process of alliance formation in any equ...

For a graph G = (V,E), a non-empty set S ⊆ V is a global offensive alliance if for every v ∈ V − S, at least half of the vertices from the closed neighborhood of v are in S. A set S ⊆ V is a global strong offensive alliance if for each vertex v ∈ V −S, a strict majority of the vertices of the closed neighborhood of v are in S. The cardinality of a minimum global (strong) offensive alliance of a...

Clinicians routinely note the challenges involved in psychotherapy with individuals with BPD, yet little research exists on the therapeutic alliance with this population. An important question is, what patient factors contribute to a disturbed alliance with individuals with BPD? Executive attention has been identified as a mechanism of BPD, and mental state vacillations (e.g., idealization/deni...

Empirical research on strategic alliances has been limited because previous studies examined alliance outcomes, and the factors associated with them, from a single partner in a manufacturing alliance. Furthermore, many of these studies have been done from a transaction cost perspective and researchers have inferred opportunistic behavior, rather than directly measuring it and observing its actu...

This study presents an interactive airline network design procedure to facilitate bargaining interactions necessitated by international code-share alliance agreements. Code sharing involves partner airlines individually maximizing their own profits, while mutually considering overall profitability, traffic gains, and quality benefits for the markets in which they cooperate with their partners. ...

OBJECTIVE The ability of alliance to predict outcome has been widely demonstrated, but less is known about the effect of the level of congruence between patient and therapist alliance ratings on outcome. In the current study we examined whether the degree of congruence between patient and therapist alliance ratings can predict symptomatic levels 1 month later in treatment. METHOD The sample c...
