For a fixed pattern graph H , let H -CONTRACTIBILITY denote the problem of deciding whether a given input graph is contractible to H . This article is part II of our study on the computational complexity of the H -CONTRACTIBILITY problem. In the first article we pinpointed the complexity for all pattern graphswith five vertices except for two pattern graphs H . Here, we present polynomial time ...
We investigate how the contractibility of actions affecting the value of an asset affects asset ownership. We examine this by testing how on-board computer (OBC) adoption affects truck ownership. We develop and test the proposition that adoption should lead to less ownership by drivers, particularly for hauls where drivers have the greatest incentive to drive in non-optimal ways or engage in re...
One of the main themes in current management control literature is study systems practices. While several studies have examined pairwise (‘dyadic’) complementarities practices to investigate whether a system exists, may also be comprised more than two (‘nondyadic systems’). We examine organizations use complementary three performance measurement uses mitigate problem effort direction. illustrat...
