For instance, the minority leader is sometimes statutorily authorized to appoint individuals to certain federal entities; he or she and the majority leader each name three
Members to serve as Private Calendar objectors; he or she is consulted with respect to reconvening the House
per the usual formulation of conditional concurrent adjournment resolutions; he or she is a traditional
member of the House Office Building Commission; he or she is a
member of the United States Capitol Preservation Commission; and he or she may, after consultation with the Speaker, convene an early
organizational party caucus or conference.
The multiple linkages model asserts a prominent role for «situational variables» — the size of the work group,
organizational policies and procedures, the prior training and experience of
members — which mediate what the leader is able to do.131 For example, the size of the school will have a significant effect on how well teachers know other teachers; it also will affect the way in which teachers form workgroups or departments to talk about their work.132 The fragmented nature of professional communities, rather than size
per se, becomes a constraint on how principals try to organize professional communities to focus on instruction and student learning.
