Let G = ( V, E ) be a simple graph. A non-empty set D ⊆ V is called global offensive alliance if dominating and for every vertex ν in − , | N [ν] ∩ |≥| |. The number the minimum cardinality of . In this paper, we give constructive characterization trees having unique alliance.

Departing from prior work that demonstrates the stickiness and stability of alliance networks resulting from embeddedness, we extend matching theory to study firms’ withdrawal from alliances. Viewing alliance withdrawal as a result of firms’ pursuit of more promising alternative partners – outside options – rather than failures in collaboration, we predict that a firm is more likely to withdraw...

The therapeutic alliance is considered as one of the active relational factors to improve the outcome of patients engaged in a psychotherapeutic process. Our objective was to examine the role played by the therapeutic alliance in psychodynamic versus supportive psychotherapy. We examined data from a previously published randomized controlled study. Outpatients suffering from depression (n=74) r...

The Global Alliance for Genomics & Health (GA4GH) held its first partner meeting in March 2014 in London. Now numbering more than 176 organizations from 25 countries, the GA4GH is working to make it possible to share genomes responsibly. Harold Varmus, Director of the National Cancer Institute, began the meeting by asking a deceptively simple question, ‘‘Are we really ready to share data?’’ Alt...
