Studies of the related IL-6 receptor complex support the contention that preformed inactive dimers of receptor subunits exist in cell membranes [28], [55], [56].
However, high levels of morphological variation among populations due to its polymorphic nature and plasticity make it difficult to clearly delimit taxonomic boundaries (Hayashi, 1978; Takasu, 1978; Kawano, 1988), and thus the taxonomic treatment of this species complex is still in contention (Kadota, 2008; Semple, 2013).

It is our contention that approaching complex policy problems as knowledge problems is thus an incomplete approach, as challenges are not always possible to reduce to a knowledge deficit, whether normative or empirical.
Similarly, population-specific differences in the allele distributions within both Class I and II major histocompatibility complex (MHC) loci support the contention that the two populations have distinct genetic characteristics [ 9, 10].
One area of contention when evaluating new complex interventions or processes of care is how to define the comparison (control) group.
Her contentions are set against a complex backdrop: spiraling health care costs and debates about Medicare.
Other critics, however, have renewed the Shelleyan and Coleridgean contention that literary experience involves a complex and profound form of knowing.
