OBJECTIVE The internal construct validity of the School Function Assessment (SFA) was determined by examining its unidimensionality and hierarchical structure. METHOD The SFA was completed for 64 elementary school children (35 with disabilities, 29 without disabilities). Data were examined through Rasch analysis. RESULTS The majority of test items (252 of 266) within the Activity Performanc...

We compute the skewness t3 and the corresponding hierarchical amplitude T3 of the divergence of the velocity field for arbitrary non-Gaussian initial conditions. We find that T3 qualitatively resembles the corresponding hierarchical amplitude for the density field, S3, in that it contains a term proportional to the initial skewness, which decays inversely as the linear growth factor, plus a con...

We propose iterative proportional scaling (IPS) via decomposable submodels for maximizing likelihood function of a hierarchical model for contingency tables. In ordinary IPS the proportional scaling is performed by cycling through the members of the generating class of a hierarchical model. We propose to adjust more marginals at each step. This is accomplished by expressing the generating class...

Abstract Purpose of this paper: The objectives of this paper are two folds: (1) utilizing hierarchical fuzzy technique for order preference by similarity to ideal solution (TOPSIS) approach to evaluate the most suitable RFID-based systems decision, and (2) to highlight key risks and benefits of radio frequency identification technology in healthcare industry. Design/methodology/approach: R...

High street decline is a topic that has received great deal of political and media attention within the last decade in UK. External factors, such as growth online retail changing economic conditions, have contributed to shift consumer needs expectations, while many high streets struggled sustain pace change. The sustainability influenced by range complex economic, environmental social factors. ...
