Because query evaluation in this scheme is in general a hard computational problem, we seek tractable instances of query evaluation.
Accordingly, instances of diverging evaluations of risk are frequently justified by the same evidence.
In instances of an equivocal evaluation, silver-enhanced in situ hybridisation was performed as previously described [ 32].
It was interesting to note that in a number of instances process evaluation publications did not provide additional information on actual implementation during the trial or associated measures.
For instance, an evaluation of the uptake of the checklist after a period of time post-implementation may allow for identification of areas in need of further development.
Performance-based indices measure the success of a grasp after its execution by lifting the object or by applying some small perturbation to it, which allows, for instance, the evaluation of the actual robustness of each grasp to store the results in a database that can be used in future grasp applications.
This is termed the 'weight of evidence' approach and used in different areas of evaluation (see for instance [ 21]).
There are still a number of significant constraints to programme implementation, including; late funding, capacity of partners, lack of a common understanding on roles and responsibilities, inadequate consultations, lack of monitoring and evaluation and instances of resistance to the programme.
Data on the performance and efficacy of the HT GMP under field conditions, for instance an evaluation of whether GMHT maize would require different herbicide regimes at different times and the consequences of that for the flora and fauna in agroecosystems, were not submitted.
For instance, the evaluation of such differing properties on the transcription of responsive genes using ChIP experiments was hindered by the deficiency of cells exhibiting the same genotypic background and properties but expressing only one of the ERs.
