For any simple connected graph $G=(V,E)$, a defensive alliance is a subset $S$ of $V$ satisfying the condition that every vertex $vin S$ has at most one more neighbour in $V-S$ than it has in $S$. The minimum cardinality of any defensive alliance in $G$ is called the alliance number of $G$, denoted $a(G)$. In this paper, we introduce a new type of alliance number called $k$-strong alliance numb...

A defensive alliance in a graph is a set $S$ of vertices with the property that every vertex in $S$ has at most one moreneighbor outside of $S$ than it has inside of $S$. A defensive alliance $S$ is called global if it forms a dominating set. The global defensive alliance number of a graph $G$ is the minimum cardinality of a global defensive alliance in $G$. In this article we study the global ...

Nevertheless, despite the government and the Ministry of Industry's emphasis as well as the efforts of Iranian companies to attract foreign partners, this is less common in Iranian home appliance industry, which indicates the risks for foreign investors.

Alliance raises many knowledge transfer and interfirm learning issues that have implications for how the alliance partners manage their cooperative learning activities in the alliance system. Many of these implications are grounded in the assumption that partners in the alliances have routines for transferring knowledge, learning, gaining management efficiencies. Thus organisations can support ...

There are two main streams of research related to alliance performance. From economic sociology perspective, relational capital is the dyadic factor determines alliance performance. Strong relational capital leads to good alliance performance. From organizational learning theory or competence-based theory perspective, alliance capability is the firm’s ability to achieve good alliance performanc...

The therapeutic alliance has been found to predict psychotherapy outcome in numerous studies. However, critics maintain that the therapeutic alliance is a by-product of prior symptomatic improvements. Moreover, almost all alliance research to date has used differences between patients in alliance as predictor of outcome, and results of such analyses do not necessarily mean that improving the al...

concerns the working alliance, commonly defined as the emotional bond established in the therapeutic dyad, and the agreement between client and therapist concerning the goals of therapy and the tasks required to achieve them (Bordin 1979; Hatcher and Barends 2006). The strength of the working alliance is a consistent predictor of outcome in psychotherapy, with stronger alliance predicting bette...
