These three constructs are derived from behavioral, normative and control beliefs.
Several rules that describe the coordination between legs were derived from behavioral experiments on forward walking stick insects (Cruse 1990) and have been implemented by Dean 1991a, b, 1992a, b; Calvitti and Beer 2000).
A priori themes were derived from behavioral change of professionals [ 25], team functioning [ 26, 27], structural capabilities at the organizational level [ 14, 28], and cultural context and competence [ 29- 32].
These categories were derived from core behavioral features of ASD (social interactions & communications, repetitive behavior), together with auxiliary features of autism (seizure, mental retardation, motor phenotype, sleep pattern) observed in humans.
Importantly, these coordinates were derived from 3D behavioral recordings, where the explained variance originated from untrained variations in behavior (Keith et al. 2009; DeSouza et al. 2011).
The paper shows how a functional model can be derived from a behavioral model produced according to the stochastic approach.
The screening data was derived from the 2008 Behavioral Risk Factor Surveillance System, a telephone survey administered to 201,157 Americans aged 50 to 75.
The conceptual framework for studying the relationships between user (child and family) and system characteristics, primary healthcare utilisation (healthcare pathways), and outcomes (appropriateness of referral to a specialised orthopaedic clinic) is derived from Andersen's Behavioral Model of Health Services Use [ 23– 25] and is presented in Fig. 1.
The variables for behavioral outcomes were derived from existing, validated instruments, including the Behavioral Risk Factor Surveillance Survey (BRFSS) and National Health and Nutritional Examination Survey NHANESS).
Physical activity questions were derived from the Youth Risk Behavioral Surveillance System questionnaire (9).
