arose naturally is: Is the bi diam always bounded by O(D 2) for graphs with diameter D ? A negative answer could imply a better lower bound. However, we have recently shown ((EMZ]) that bi diam(G) = (D 2 G), where G is any 2-edge connected graph, and thus the answer to the question is positive (this result was independently proved by D]). It implies that, using the same technique we used, one c...

Focusing on the working relationship between Marketing Managers and Sales Managers, our study examines two dimensions of interpersonal conflict: dysfunctional conflict and functional conflict. Drawing on relevant theory, we include three communication variables – frequency, bidirectionality, and quality – as antecedents in our structural model. Using these explanatory variables we predict the t...

BACKGROUND Unhealthy alcohol use includes the spectrum of alcohol consumption from risky drinking to alcohol use disorders. Routine alcohol screening, brief intervention (BI) and referral to treatment (RT) are commonly endorsed for improving the identification and management of unhealthy alcohol use in outpatient settings. However, factors which might impact screening, BI, and RT implementation...

We propose to model breast tissue in mammograms covering both density and tissue patterns. The breast tissue density modelling is based on the global density distribution of the breast region. We segment the whole breast region into a number of uniform density sub-regions and construct an overall density model of the breast using the relative proportions of these sub-regions. The breast tissue ...
