A contemporary school of thought, called inclusive legal positivism, endorses the Social Thesis, namely, that the basic conditions of legal validity derive from social facts, such as social rules or conventions which happen to prevail in a given community.
A summary of the internal reliability (inter-item consistency) and convergent validity derived from the CFA of the constructs can be found in Table 4. Values of composite reliability greater than 0.7 for established scales and 0.6 for new scales are indicative of internal consistency.
Within this narrative, quality is conceptualised in relation to theoretical constructs such as validity or rigour, derived from the positivist paradigm, and is demonstrated by the inclusion of certain recommended methodological techniques.
Validity often derives from whether things "work" in a particular environment.
For social validity, the model is also compared with 27 previous delegation models with respect to socio-technical validity parameters derived from social principles already accepted in the human society.
The solution approach is based on Lagrangian relaxation, improved with validity constraints derived from the finite set of all possible combinations of mean demand and variance.
The items 5a c concerning external validity were derived from Mazaheri et al. (2012).
Unless the used outcome measures have established reliability and validity, data derived from them are subject to bias.
It is important that only validated questionnaires are employed; otherwise, the outcome measures used have less established reliability and validity, data derived from them are subject to bias, and comparisons between the results of different studies are problematic.
According to O'Sullivan and Weir (2011, pp.21 22) the type of consequential validity is essentially derived from successful realization of construct validity.
