This knowledge can provide a basis for selecting insecticides and for ascertaining continued susceptibility to insecticides already in use.
Furthermore, we used prospectively recorded data for diagnosis, for construction of family relationships and for ascertaining socioeconomic information, thus minimising recall bias and other errors associated with self-reporting.
These data are critical for evaluating the molecular similarity of the Hawaiian red algal collections to those in other locations and for ascertaining the number of distinct genetic lineages of each species in the Hawaiian Islands.
Oikopleura and Ciona therefore provide us with a model for investigating the role of mechanisms such as co-option and divergence in notochord evolution and for ascertaining the extent of modifications that its genetic toolkit can sustain without major morphogenetic changes.
As with most studies based on SEER-Medicare, Medicare claims, or other sources of administrative and claims data, we did not include a "true gold standard" with perfect sensitivity and specificity for ascertaining the prevalences and incidences of the conditions.
Total 21 samples were collected and analyzed for various physical and chemical parameters, like pH, electrical conductivity, Total dissolved solids, total hardness, total alkalinity, calcium, magnesium, sodium and potassium, and anions, such as chloride, bicarbonate, sulphate, and nitrate, for ascertaining the potability of water.
Second, associations between pre-transport variables and adverse outcomes could not be determined, both because pre-transport status was poorly documented, and because studies lacked standard definitions and methods for ascertaining adverse events.
Zhu's ultimate purpose was pragmatic rather than epistemic; that is, he was laying out the concepts, framework, and practices that he deemed most conducive to self-cultivation, self-realization, and ethical practice, rather than formulating objectively accurate concepts, systems, and methods for ascertaining objective truths about the world.
The validation studies conducted to date suggest that administrative data are generally sensitive and specific for ascertaining cases of hip fracture [ 12], although this will vary with the type of hip fracture [ 13].
These belief systems clearly extend to various degrees across many cultures, and the VA protocol and other requirements for ascertaining cause of death need to embed approaches to managing these belief systems within the process of data collection.
Okura et al. [ 8] observed good agreement between survey and administrative data for ascertaining cases of diabetes, hypertension, myocardial infarction, and stroke.
