In this paper we obtain several tight bounds on different types of alliance numbers of a graph, namely (global) defensive alliance number, global offensive alliance number and global dual alliance number. In particular, we investigate the relationship between the alliance numbers of a graph and its algebraic connectivity, its spectral radius, and its Laplacian spectral radius.

BACKGROUND Research has shown that the therapeutic alliance plays an important role in enhancing treatment outcome among individuals with a variety of disorders, including posttraumatic stress disorder (PTSD). However, the therapeutic alliance and treatment outcome has not yet been studied in dissociative disorders (DD). OBJECTIVES The current study sought to investigate the impact of allianc...

We examined the therapeutic alliance in evidence-based treatment for children (N=97, 24 girls and 73 boys, ages 6-13 years) referred clinically for oppositional, aggressive, and antisocial behavior. We predicted that the quality of the child-therapist alliance would be related to therapeutic improvements in the children at the end of treatment and that the alliance would be predicted by allianc...

Let G = (V, E) be a graph and let W:V→N be a non-negative integer weighting of the vertices in V. A nonempty set of vertices S ⊆ V is called a weighted defensive alliance if ∀v ∈ S ,∑u∈N[v]∩S w(u) ≥ ∑x∈N(v)−S w(x). A non-empty set S ⊆ V is a weighted offensive alliance if ∀v ∈ δS ,∑u∈N(v)∩S w(u) ≥ ∑x∈N[v]−S w(x). A weighted alliance which is both defensive and offensive is called a weighted pow...

This research focuses on services based on alliance and devises a novel concept called service alliance. Service alliance uses service as the unit that companies can exchange, furnish, and share services in the alliance. Service alliance emphasizes on the representation and exchange for value of single service from an individual company. This research utilizes game theory to discuss the best ac...

The determinants of strategic alliance performance have not been explored adequately in the literature. Empirical studies abound with numerous kinds of performance measures but, thus far, there is no coherent theoretical basis for the determinants of alliance performance. In this article we present a theoretical framework for understanding alliance performance in terms of its key antecedents. W...

We model the two-Wrm alliance as an iterated prisoners’ dilemma game with an exit option and test several theoretical predictions over two experimental studies. A new major eVect on alliance performance arises by including the exit option (i.e., the option to end the alliance and receive a Wxed payoV that is less than the payoV for mutual cooperation but greater than the payoV for mutual defect...

Most of the literature on the alliance-outcome association is based exclusively on differences between patient reports on alliance. Much less is known about the unique contribution of the therapist's report to this association across treatment, that is, the association between therapist-reported alliance and outcome over the course of treatment, after controlling for the patient's contribution....

where, according to Schiffer, the concept of an F is pleonastic just in case the concept itself licenses entailments of the form: S ⇒ ∃xFx. These are what he calls "somethingfrom-nothing" entailments and the various practices in which such entailments are made are what he calls "hypostatisizing practices" (p.57). The concept of a proposition is pleonastic, according to this definition, because ...

This paper describes several Jet Propulsion Laboratory research efforts being conducted to support Mars sample return in the coming decade. After describing the 2003/05 mission scenario, we provide an overview of new technologies emerging from three complimentary research efforts: Long Range Science Rover, Sample Return Rover, and FIDO Rover. The results show improvements in planning, navigatio...
