Keystone sector methodology applied to Portugal
actors not including the actor i. In other words, if actor i wants to contact actor j, actor k
must be used as an intermediary, which gives him a certain responsibility to actors i and
j. If we count all the minimum paths, which pass through k, we have the measure of his
power in the network. To test these positions we applied both the Closeness and
Betweeness UCINET calculations. The results are showed in Table 4:

* Slightly less than the 1Std+mean value.
Bold for ‘at least 2 top places in all’.
The higher the value of Closeness, the shortest is the path from the entity to
connect other entities in the community. In the present case we can say that the Private
Construction Firm reaches the most other agents with the fewest steps in the Money
matrix (more than 1Std higher than the mean). This result is consistent with the
hypothesis of the huge increase in construction activity and the housing boom over the
last decade.
The higher the value of Betweeness, the more potential an actor has to control
third-party relationships. Again, the Private Construction Firm in Money matrix, but
also the Local Authority in Information and the Public Health Center for Organization
matrices.
