However, learning seems slow, it is said, because the environment (context) in which it occurs is complex and constantly changing.
For example, it is well known that tumor hypoxia negatively impacts clinical outcomes, but the actual mechanism by which this occurs is complex and may include radiation resistance, increased tumor invasion, migration, increased survival and decreased drug sensitivities [37].
While our data are consistent with the model that Int6 reduction can induce MMT, the molecular mechanism for how this occurs is complex and not resolved in this study.
Humanitarian responses and the environments in which they occur are complex, and overlap with many large fields (eg. global health, medicine, urban planning, engineering, gender studies, or military operations).
The concentration of this HIV epidemic in Henan Province is striking and the reasons for why this occurred are complex.
The mechanisms by which intergenerational adverse effects occur are complex.
Interpretation for data in the second shell where multiple scattering effects can occur is complex, particularly in multiple cation systems.
Two of these species, known currently as Mediterranean (MED) and Middle East-Asia Minor 1 (MEAM1), until formal revised description of the complex occurs, are considerable pests of agriculture and have been spread globally through trade in ornamental species [ 13, 14].
On the other hand, how evolution occurs is a complex matter subject to theory.
The contexts in which training evaluations occur are extremely complex.
