A strong defensive alliance in a graph G = (V, E) is a set of vertices A ⊆ V , for which every vertex v ∈ A has at least as many neighbors in A as in V − A. We call a partition A, B of vertices to be an alliance-free partition, if neither A nor B contains a strong defensive alliance as a subset. We prove that a connected graph G has an alliance-free partition exactly when G has a block that is ...

The Grand Alliance HDTV System has been designed for the needs and requirements of North America. The system has a great deal of flexibility to facilitate inter-operability and is heavily based on international standards. The Grand Alliance and the FCC Advisory Committee on Advanced Television Service have been working together to complete the design of the Grand Alliance HDTV System. When a te...

This paper presents a formal analysis of FIDO, a protocol developed by the FIDO Alliance project, and which aims to provide either a passwordless experience or an extra security layer for user authentication over the Internet. We model the protocol using the applied pi-calculus and run our analysis using ProVerif. Our analysis shows that ignoring some optional steps of the standard could lead t...

Stephen Schiffer 2003 presents six arguments against the Fregean model of propositions, according to which propositions are (a) the referents of that-clauses and (b) structured entities made out of concepts. Schiffer advances an alternative view: propositions are unstructured pleonastic entities. My purpose is to argue in favour of the main tenets of the Fregean model by countering each of Schi...

Alliances are increasingly becoming common in all business relationships. In particular, alliances that facilitate the sharing of information between alliance partners as a result of collaborative experience is increasing in importance. Market orientation is a construct that can mediate the relationship between a firm’s collaborative experience and their alliance performance. This paper examine...

This meta-analysis synthesizes research on the relation between patient adult attachment style and patient-rated working alliance. A random-effects model was used to calculate the mean weighted product-moment correlation (r) for 24 studies (12 published in peer-reviewed journals and 12 unpublished doctoral dissertations) of individual outpatient therapy with adults. The mean weighted r for atta...

W investigate whether partners in a brand alliance should be similar or dissimilar in brand image to foster favorable perceptions of brand fit. Using a Bayesian nonlinear structural equation model and evaluations of 1,200 brand alliances, we find that the conceptual coherence in brand personality profiles predicts attitudes towards a brand alliance. More specifically, we find that similarity in...

The present review is a comprehensive examination of the therapist's personal attributes and in-session activities that positively influence the therapeutic alliance from a broad range of psychotherapy perspectives. Therapist's personal attributes such as being flexible, honest, respectful, trustworthy, confident, warm, interested, and open were found to contribute positively to the alliance. T...

The aim of this paper is to deal with the problem of coordination for online markets where a seller registers to an online market to sell an item. The seller and the owner of the market then form an alliance to generate revenue through online sales. However, the efficiency and stability of the alliance highly relies on the contract that specifies the way to split the revenue and costs over the ...

Let Γ = (V,E) be a simple graph. For a nonempty set X ⊆ V , and a vertex v ∈ V , δX(v) denotes the number of neighbors v has in X. A nonempty set S ⊆ V is a defensive k-alliance in Γ = (V,E) if δS(v) ≥ δS̄(v)+k, ∀v ∈ S. A defensive k-alliance S is called global if it forms a dominating set. The global defensive k-alliance number of Γ, denoted by γ k(Γ), is the minimum cardinality of a defensive ...
