A hierarchical knowledge structure was characterised as "a coherent, explicit and systematically principled structure, hierarchically organised" which "attempts to create very general propositions and theories, which integrate knowledge at lower levels, and in this way shows underlying uniformities across an expanding range of apparently different phenomena" (1999a: 162, 162).
Seemingly straightforward averaging approaches may be heavily biased by an underlying non-uniformity in the distribution of the data.
Yet this activity would be no more than the compiling of a catalog of facts unless an underlying recognition of uniformities and correlations enabled the investigator to choose what to measure out of an infinite range of choices available.
In this study, a modified analytic induction technique based on the accounts described by Johnson [ 19] and Bondas [ 20] was used to compare informants' accounts so as to identify similarities and differences, thereby constructing the uniformities underlying and defining the emergent themes/categories.
One factor underlying this lack of uniformity in immune response may be the stochastic nature of genetic drift acting on regulatory regions or functional genes associated with immunity.
Our results indicate that the underlying fiber architecture, fiber density, and uniformity of nerve fiber direction affect anisotropy values of the various structures.
Subsequently, CdS, ZnO and ITO layers are orderly deposited on the Mo/CIS wire, and each upper layer ensures full contact with the underlying layer, resulting in an excellent structural uniformity along circumference of the FSC.
Therefore, the roughness, uniformity, and flatness of the substrate or the underlying film and the gap between the blade and the substrate determine the quality and thickness of the deposited film.
Accordingly, such thin PR thickness in turn limits the process capability of dry etcher and may bring a lot of problems including accurate size control, LER, and etch uniformity when the PR patterns are transferred to underlying substrate materials.
Hence, when discussing the validity of VIA as a screening method for cervical cancer there is concern about a lack of standardized test definition, differences in test providers skills, underlying prevalence of other sexually transmitted infections and lack of uniformity in the application of gold standard for disease definition [ 17].
