data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Let G be a bipartite graph with bicoloration {A, B}, |A| = |B|, and let w : E(G) -» K where K is a finite abelian group with k elements. For a subset S c E(G) let w(S) = IIeE s (e).A Perfect matching M c E(G) is a w-matching if w(M) = 1. A characterization is given for all w's for which every perfect matching is a w-matching. It is shown that if G = Kk+1,k+1 then either G has no w-matchings or ...
Let G be a bipartite graph with a bicoloration {A, B}, |A| = |B|, and let w : E(G) → K where K is a finite abelian group with k elements. For a subset S ⊆ E(G) let w(S) = ∏e∈S w(e). A perfect matching M ⊆ E(G) is a w-matching if w(M) = 1. It is shown that if deg(a) ≥ d for all a ∈ A, then either G has no w-matchings, or G has at least (d − k + 1)! w-matchings.
this study investigated how group formation method, namely student-selected vs. teacher-assigned, influences the results of the community model of teaching creative writing; i.e., group dynamics and group outcome (the quality of performance). the study adopted an experimental comparison group and microgenetic research design to observe the change process over a relatively short period of time. ...
