Validation, research

A discussion of test methodology is beyond the scope of the present paper. However, the fact that established tests do not accurately reflect the behavior of materials in fires has been widely recognized (9), and the search for more meaningful techniques for the evaluation of engineering materials has continued to be a valid research objective. The development of the cone calorimeter, a bench-scale tool for the evaluation of fire properties of materials (10a) at NBS, is of particular significance in this context. 

Many of the risks and constraints affecting commercial organic agriculture can be removed by objectively validated research and development, as well as policy activities, such as. the improvement of infrastructure and the establishment of certification bodies in African countries. Other constraints, such as long distances to markets can only be removed by the establishment of new markets for organic products in Africa, or nearer locations like the middle East. 

Looking back, these remarks set the stage for subsequent construct validation research (Cronbach Meehl 1955) the phrase independent estimate anticipated external validation, whereas most instructive depicts an empirically based form of competitive support. To Galton (1890), like subsequent participants of the mental measurement movement, scientific measures were not all seen as equally important (Lubinski 1996). Importance was to be calibrated against the breadth... 

Are my sources reporting valid research Is your source the original researcher or is he or she reporting someone else s study If the information is being reported secondhand, has your source been accurate and clear Is the original source named or referenced in some way so that the information could be checked ...

Internal validity is the validity of a particular study and its claims. It is a cause-effect phenomenon. To assure internal validity, researchers are strongly advised to include a reference or control arm when evaluating a test condition. A reference arm is a treatment or condition in which the researcher has a priori knowledge of the outcome. For example, if a bacterial strain of Staphylococcus aureus, when exposed to a 4% chlorhexidine gluconate (CHG) product, is generally observed to xmdergo a 2 logio reduction in population after 30 sec... 

The da Vincian and Renaissance-era concept of dimostrazione represents a fundamental departure from the purely abstract and faith-driven scholarship that was prevalent in the Middle Ages. During that time period, only consistency with religious doctrine was required to validate research results. Dimostrazione for da Vinci and for us today means direct feedback between research and the world and between processes of knowledge acquisition and verification.

This is the most scientifically valid research. With extraneous variables kept under control, matched groups are subjected to different treatments, and observed response differences are checked for statistical significance. The aim is to capture cause-and-effect relationships by eliminating competing explanations of the observed findings. 

Furthermore, findings from the on-going stability investigation are a part of the product validation. This research may, for example, show that a solution would be better stored in a glass or plastic bottle. Information that is obtained during the validation research can later be used for the assessment of deviations during routine productions. 

Unlike HPLC, TLC is an off-line technique sample application, chromatographic development, and detection are separated in time and space. The validation procedure itself and the significance of the various analytical performance parameters during validation research are different depending on the degree of instrumentation (see data in Table 5). 

With these obstacles in mind, the role of highway safety researchers and highway safety program specialists is to find the ways to implement valid research findings without compromising various other social values.
